AB Avruch J, Long X, Ortiz-Vega S, Rapley J, Papageorgiou A, Dai N. Amino acid regulation of tor complex 1. Am J Physiol Endocrinol Metab 296: E592-E602, 2009. First published September 2, 2008; doi:10.1152/ajpendo.90645.2008.-TOR complex 1 (TORC1), an oligomer of the mTOR ( mammalian target of rapamycin) protein kinase, its substrate binding subunit raptor, and the polypeptide Lst8/G beta L, controls cell growth in all eukaryotes in response to nutrient availability and in metazoans to insulin and growth factors, energy status, and stress conditions. This review focuses on the biochemical mechanisms that regulate mTORC1 kinase activity, with special emphasis on mTORC1 regulation by amino acids. The dominant positive regulator of mTORC1 is the GTP-charged form of the ras-like GTPase Rheb. Insulin, growth factors, and a variety of cellular stressors regulate mTORC1 by controlling Rheb GTP charging through modulating the activity of the tuberous sclerosis complex, the Rheb GTPase activating protein. In contrast, amino acids, especially leucine, regulate mTORC1 by controlling the ability of Rheb-GTP to activate mTORC1. Rheb binds directly to mTOR, an interaction that appears to be essential for mTORC1 activation. In addition, Rheb-GTP stimulates phospholipase D1 to generate phosphatidic acid, a positive effector of mTORC1 activation, and binds to the mTOR inhibitor FKBP38, to displace it from mTOR. The contribution of Rheb's regulation of PL-D1 and FKBP38 to mTORC1 activation, relative to Rheb's direct binding to mTOR, remains to be fully defined. The rag GTPases, functioning as obligatory heterodimers, are also required for amino acid regulation of mTORC1. As with amino acid deficiency, however, the inhibitory effect of rag depletion on mTORC1 can be overcome by Rheb overexpression, whereas Rheb depletion obviates rag's ability to activate mTORC1. The rag heterodimer interacts directly with mTORC1 and may direct mTORC1 to the Rheb-containing vesicular compartment in response to amino acid sufficiency, enabling Rheb-GTP activation of mTORC1. The type III phosphatidylinositol kinase also participates in amino acid-dependent mTORC1 activation, although the site of action of its product, 3 ' OH-phosphatidylinositol, in this process is unclear.

Retinol-binding protein 4 is associated with impaired glucose tolerance but not with whole body or hepatic insulin resistance in Mexican Americans. Am J Physiol Endocrinol Metab 296: E758-E764, 2009. First published February 3, 2009; doi:10.1152/ajpendo.90737.2008.-Retinol-binding protein-4 (RBP4), a novel protein secreted mainly by adipose tissue, has been associated with insulin resistance in obese subjects and in individuals with type 2 diabetes mellitus (T2DM). We examined the relationship between plasma RBP4 levels, expression of RBP4 in skeletal muscle and adipose tissue, and insulin sensitivity in Mexican Americans with varying degrees of obesity and glucose tolerance. Seventy-two subjects [16 lean normal-glucose-tolerant (NGT), 17 obese NGT, and 39 subjects with impaired fasting glucose/impaired glucose tolerance/T2DM] received an oral glucose tolerance test (OGTT) and euglycemic-hyperinsulinemic clamp. Insulin secretion was measured as insulinogenic index during OGTT. In a subset of subjects, hepatic glucose production was measured by 3-[(3)H] glucose infusion, biopsies of the vastus lateralis muscle and subcutaneous adipose tissue were obtained under basal conditions, and quantitative RT-PCR was performed to measure the RBP4 mRNA gene expression. Plasma RBP4 was significantly elevated in impaired glucose tolerance/T2DM compared with NGT lean or obese subjects. Plasma RBP4 levels correlated with 2-h glucose, triglycerides, and hemoglobin A(1c). There was no association between RBP4 levels and whole body insulin sensitivity measured with either the euglycemic insulin clamp or OGTT, basal hepatic glucose production rates, and the hepatic insulin resistance index. There was no correlation between plasma RBP4 levels and indexes of insulin secretion. RBP4 mRNA expression in skeletal muscle was similar in lean NGT subjects, obese NGT subjects, and T2DM subjects. There was no difference in RBP4 mRNA expression in adipose tissue between lean and obese NGT subjects or between NGT and T2DM individuals. Plasma RBP4 levels are elevated in T2DM and associated with impaired glucose tolerance, but not associated with obesity or insulin resistance or impaired insulin secretion in Mexican Americans.

AB Experimental hepatopulmonary syndrome (HPS) after common bile duct ligation (CBDL) in rat is accompanied by increased lung vascular endothelial endothelin B (ET(B)) receptor expression and increased circulating levels of endothelin-1 (ET-1). The onset of HPS is hypothesized to be triggered by ET-1/ET(B) receptor activation of endothelial nitric oxide synthase (eNOS)-derived NO production in the pulmonary endothelium. However, whether functional pulmonary vascular ET(B) receptors are required for the development of experimental HPS is not defined. We evaluated the effects of vascular ET(B) receptor deficiency on the development of experimental HPS. The molecular and physiological alterations of HPS were compared in 2-wk CBDL wild-type and ET(B) receptor-deficient (transgenic sl/sl) rats. Relative to wild-type rats, basal hepatic and plasma ET-1 levels were elevated in sl/sl controls although, unlike wild-type animals circulating ET-1 levels, did not increase further after CBDL in sl/sl animals. In contrast to wild-type animals, ET(B) receptor-deficient rats did not develop increased Akt and eNOS expression and activation and did not develop gas exchange abnormalities of HPS after CBDL. There was a similar degree of pulmonary intravascular monocyte accumulation in both 2-wk CBDL sl/sl and wild-type animals. In conclusion, ET(B) receptor deficiency inhibits lung Akt/eNOS activation and prevents the onset of experimental HPS after CBDL. This effect is independent of inhibition of pulmonary intravascular monocyte accumulation. These results demonstrate that ET-1/ET(B) receptor signaling plays a key role in the initiation of experimental HPS.

Mechanical work and energetic analysis of eccentric cardiac remodeling in a volume overload heart failure in rats. Am J Physiol Heart Circ Physiol 296: H1117-H1124, 2009. First published February 6, 2009; doi:10.1152/ajpheart.01120.2008.-Eccentric cardiac remodeling seen in dilated cardiomyopathy or regurgitant valvular disease is a well-known process of heart failure progression, but its mechanoenergetic profile has not been yet established. We made a volume overload (VO) heart failure model in rats and for the first time investigated left ventricular (LV) mechanical work and energetics in cross-circulated whole heart preparations. Laparotomy was performed in 14 Wistar male rats, and abdominal aortic-inferior vena caval shunt was created in seven rats (VO group). Another seven rats underwent a sham operation without functional shunt (Sham group). LV dimensions changes were followed with weekly transthoracic echocardiography. Three months after surgery, we measured LV pressure and volume and myocardial O(2) consumption in isolated heart cross circulation. LV internal dimensions in both systolic and diastolic phases were significantly increased in the VO group versus the Sham group (P < 0.05). LV pressure was markedly decreased in the VO group versus in the Sham group (P < 0.05). LV end-systolic pressure-volume relation shifted downward, and myocardial O(2) consumption related to Ca(2+) handling significantly decreased. The contractile response to Ca(2+) infusion was attenuated. Nevertheless, the increase in Ca(2+) handling-related O(2) consumption per unit change in LV contractility in the VO group was significantly higher than that in the Sham group (P < 0.05). The levels of sarco(endo) plasmic reticulum Ca(2+)-ATPase 2a protein were reduced in the VO group (P < 0.01). In conclusion, VO failing rat hearts had a character of marked contractile dysfunction accompanied with less efficient energy utilization in the Ca(2+) handling processes. These results suggest that restoring Ca(2+) handling in excitation-contraction coupling would improve the contractility of the myocardium after eccentric cardiac remodeling.

First published February 11, 2009; doi:10.1152/ajprenal.90575.2008.-Methylglyoxal (MG), a highly reactive carbonyl compound generated by carbohydrate oxidation and glycolysis, is the major precursor of protein glycation and induces cytotoxicity leading to apoptosis. Although recent studies have emphasized that MG accumulates in not only chronic oxidative stress-related diseases but also acute hypoxic conditions, the pathogenic contribution of MG in acute diseases is unclear. MG is efficiently metabolized by the glyoxalase system, namely, glyoxalase I. We investigated the pathophysiological role of glyoxalase I as an MG detoxifier in rat renal ischemia-reperfusion (I/R) injury. I/R-induced tubulointerstitial injury was associated with a deterioration in renal glyoxalase I activity independent of its cofactor, GSH, as well as an increase in renal MG level. In in vitro studies, knockdown of glyoxalase I by small interference RNA transfection in rat tubular cells exacerbated cell death by hypoxia-reoxygenation compared with control cells. We also examined whether glyoxalase I overexpression prevented renal I/R damage in rats overexpressing human glyoxalase I with enzyme activity in the kidney 17-fold higher than in wild-type. The histological and functional manifestations of I/R in these rats were significantly ameliorated in association with a decrease in intracellular MG adduct accumulation, oxidative stress, and tubular cell apoptosis. In conclusion, glyoxalase I exerts renoprotective effects in renal I/R injury via a reduction in MG accumulation in tubular cells.

DT Article
ID POPULAR-MUSIC; BEHAVIOR; MEDIA; RISK; TELEVISION; WOMEN; INTERCOURSE;
CHILDREN; VIOLENT; SCALE
AB Background: Two thirds of all sexual references in Music are degrading in nature, yet it remains uncertain whether these references promote earlier sexual activity. The purpose of this study was to determine if exposure to lyrics describing degrading sex in popular music is independently associated with Sexual behavior in a cohort of urban adolescents.
Methods: All ninth-grade health students at three large urban high schools completed in-school surveys in 2006 and 2007. Participants' exposure to lyrics describing degrading sex was computed with overall music exposure and content analyses of their favorite artists' songs. Outcomes included sexual intercourse and progression along a noncoital sexual continuum. Multivariable regression was used to assess independent associations between exposure to lyrics describing degrading sex and outcomes.
Results: The 711 participants were exposed to 14.7 hours each week of songs with lyrics describing degrading sex (SD=17.0). Almost one third of participants (n=216) had previously been sexually active. Compared to those with the least exposure to lyrics describing degrading sex, those with the most exposure were more than twice as likely to have had sexual intercourse (OR=2.07; 95% CI=1.26, 3.41), even after adjusting for all covariates. Similarly, among those who had not had Sexual intercourse, those in the highest tertile of exposure to lyrics describing degrading sex were nearly twice as likely to have progressed along a noncoital sexual continuum (OR=1.88; 95% CI = 1.23, 2.88) compared to those ill the lowest tertile. Finally, the relationships between exposure to lyrics describing nondegrading sex and sexual outcomes were not significant.
Conclusions: This study supports all association between exposure to lyrics describing degrading sex in popular music and early sexual experience among adolescents.

AB Objectives. We examined associations between patient characteristics and self-reported difficulties in accessing mental health and general medical care services.
Methods. Patients were recruited from the Continuous Improvement for Veterans in Care-Mood Disorders study. We used multivariable logistic regression analyses to assess whether predisposing (demographic characteristics), enabling (e.g., homelessness), or need (bipolar symptoms, substance abuse) factors were associated with difficulties in obtaining care, difficulties in locating specialty providers, and forgoing care because of cost.
Results. Patients reported greater difficulty in accessing general medical services than in accessing psychiatric care. Individuals experiencing bipolar symptoms more frequently avoided psychiatric care because of cost (odds ratio (OR]=2.43) and perceived greater difficulties in accessing medical specialists (OR=2.06). Homeless individuals were more likely to report hospitalization barriers, whereas older and minority patients generally encountered fewer problems accessing treatment.
Conclusions. Need and enabling factors were most influential in predicting self-reported difficulties in accessing care, subsequently interfering with treatment dynamics and jeopardizing clinical outcomes. Efforts in the Department of Veterans Affairs to expand mental health care access should be coupled with efforts to ensure adequate access to general medical services among patients with chronic mental illnesses.

TI The Coordination of Breathing and Swallowing in Chronic Obstructive
Pulmonary Disease

ID SUBGLOTTIC AIR-PRESSURE; PASSY-MUIR VALVE; BOLUS VOLUME; NORMAL ADULTS;
RESPIRATORY PATTERNS; PHASE-RELATIONSHIPS; APNEA DURATION; SOLID FOOD;
PHARYNGEAL; ASPIRATION
AB Rationale. During deglutition, a strongly preferred exhale-swallow-exhale pattern has been shown in healthy adults. Disruption of this pattern can provoke prandial aspiration. Impaired coordination of breathing and swallowing has been measured in patients with chronic obstructive pulmonary disease (COPD) during the exacerbated state, but no reports describe the coordination of breathing and swallowing in stable patients with COPD during oral intake.
Objectives: To test the hypothesis that persons with moderate to severe COPD would show disordered coordination of breathing and swallowing during oral intake when compared with a matched, healthy control group.
Methods: This study used a prospective, repeated measures design using 25 subjects with COPD and 25 control subjects. Respiratory inductance plethysmography and nasal thermistry were used simultaneously to track respiratory signals. Submental surface EMG was used to mark the presence of each swallow within the respiratory cycle. Data were recorded while participants randomly and spontaneously swallowed solids and semi-solids.
Measurements and Main Results: Logistic regression showed that participants with COPD swallowed solid food during inhalation more frequently than normal subjects (P = 0.002) and had a significantly higher rate of inhaling after swallowing semi-solid material (P < 0.001). Subjects with COPD also swallowed pudding at low VT significantly more often than they did the cookie (P = 0.006). Conversely, the control subjects swallowed cookie at low VT significantly more often than pudding (P = 0.034). Significant differences in deglutitive apnea durations were also found.
Conclusions: Patients with COPD exhibit disrupted coordination of the respiratory cycle with deglutition. Disrupted breathing-swallowing coordination could increase the risk of aspiration in patients with advanced COPD and may contribute to exacerbations.

AB OBJECTIVE. The objective of our study was to evaluate a large cohort of patients with PET/CT to determine whether qualitative (visual) assessment, quantitative standardized uptake value (SUV), or standardized uptake ratio (SUR) techniques should be used when attempting to characterize adrenal masses in patients with cancer.
MATERIALS AND METHODS. The study group was composed of 150 consecutive patients (78 men, 72 women; mean age, 60 years; range, 24-88 years) with documented adrenal lesions. All patients were known to have an underlying primary malignancy and were referred for PET/CT to evaluate the underlying primary and metastatic tumor burden. Definitive lesion characterization was determined by evaluating all histologic adrenal specimens and all relevant prior and follow-up CT scans, including unenhanced, contrast-enhanced, and delayed contrast-enhanced washout studies.
RESULTS. Of the 139 benign lesions, 109 were considered benign by CT densitometry measurements and 135 by qualitative PET data. Qualitative PET characterized 28 of 30 benign lesions that were considered indeterminate by unenhanced CT. All 26 malignant lesions were characterized by PET: All showed qualitative and quantitative signal intensity greater than the liver. By combining unenhanced and qualitative CT data with the retrospective PET data, the analysis yielded a sensitivity of 100% for the detection of malignancy, a specificity of 99%, a positive predictive value (PPV) of 93%, a negative predictive value (NPV) of 100%, and an accuracy of 99% (Table 1). Conversely, for the detection of benignity, the sensitivity, specificity, PPV, NPV, and accuracy were 99%, 100%, 100%, 93%, and 99%, respectively.
CONCLUSION. PET/CT is a highly accurate method for differentiating benign from malignant adrenal masses particularly when using qualitative, rather than quantitative, PET data. The routine use of quantitative mean or maximal SUV or SUR data may be unnecessary. Occasional benign lesions do show mild to moderate increased FDG uptake compared with that of the liver and may mimic some malignant lesions. Without evidence that these lesions are benign by unenhanced CT densitometry or adrenal mass stability or growth from previous CT scans, we recommend that these lesions be characterized using contrast-enhanced washout tests and that if those tests are inconclusive, using percutaneous biopsy if early lesion characterization is mandatory.

TI Endoscopic Repair of Gluteus Medius Tendon Tears of the Hip

DT Article
DE gluteus medius tendon tear; abductor tendon; arthroscopy; lateral hip
pain
ID ROTATOR-CUFF TEAR; TROCHANTERIC BURSITIS; ABDUCTOR MECHANISM;
ARTHROSCOPY; PAIN
AB Background: Tears of the gluteus medius tendon at the greater trochanter have been termed "rotator cuff tears of the hip." Previous reports have described the open repair of these lesions.
Hypothesis: Endoscopic repair of gluteus medius tears results in successful clinical outcomes in the short term.
Study Design: Case series; Level of evidence, 4.
Methods: Of 482 consecutive hip arthroscopies performed by the senior author, 10 patients with gluteus medius tears repaired endoscopically were evaluated prospectively. Perioperative data were analyzed on this cohort of patients. There were 8 women and 2 men, with an average age of 50.4 years (range, 33-66 years). Patients had persistent lateral hip pain and abductor weakness despite extensive conservative measures. Diagnosis was made by physical examination and magnetic resonance imaging and was confirmed at the time of endoscopy in all cases. At the most recent follow-up, patients completed the Modified Harris Hip Score and Hip Outcomes Score surveys.
Results: At an average follow-up of 25 months (range, 19-38 months), all 10 patients had complete resolution of pain; 10 of 10 regained 5 of 5 motor strength in the hip abductors. Modified Harris Hip Scores at 1 year averaged 94 points (range, 84-100), and Hip Outcomes Scores averaged 93 points (range, 85-100). There were no adverse complications after abductor repairs. Seven of 10 patients said their hip was normal, and 3 said their hip was nearly normal.
Conclusion: With short-term follow-up, endoscopic repair of gluteus medius tendon tears of the hip appears to provide pain relief and return of strength in select patients who have failed conservative measures. Further long-term follow-up is warranted to confirm the clinical effectiveness of this procedure.

AB Endoscopic mucosal resection (EMR) is being advocated its a diagnostic, staging, and therapeutic technique for the management of Barrett esophagus (BE)-related neoplasia. With the emergence of new endoluminal therapy including EMR for the treatment of BE-related superficial adenocarcinomas, accurate staging has become crucial to select patients for different treatment arms. Intramucosal adenocarcinomas can be successfully treated by endoluminal techniques, whereas submucosal invasive tumors with a greater risk of lymph node metastasis are likely candidates for esophagectomy. Endoscopic ultrasound (EUS) is used to stage superficial BE-related neoplasms, vet endoscopic staging can be incongruent to that obtained after pathologic examination. In this Study, we Sought to determine morphologic factors, which may influence EUS staging in 35 cases with intramucosal adenocarcinoma diagnosed by subsequent EMR, focusing on tumor characteristics and structural changes associated with BE. Among the latter duplication of the muscularis mucosae, either fragmented or well-organized, was seen in 64% of 11 cases that were overstaged as having submucosal invasion by EUS, compared with 38% of those accurately staged. A greater vertical thickness of the tumor was also associated with overstaging by EUS (1.61 +/- 0.75 mm in the discordant vs. 1.16 +/- 0.67 mm in the concordant groups, P = 0.028). The results illustrate how morphologic factors may affect EUS staging of superficial esophageal adencearcinomas. EUS alone is not sufficient for staging these neoplasms precisely, and to accurately stratify patients into different treatment arms. EMR should play a role as a complementary staging modality.

AB Antiretroviral-therapy has dramatically changed the course of HIV infection and HIV-infected (HIV(+)) individuals are becoming more frequently eligible for solid-organ transplantation. However, only scarce data are available on how immunosuppressive (IS) strategies relate to transplantation outcome and immune function. We determined the impact of transplantation and immune-depleting treatment on CD4+ T-cell counts, HIV-, EBV-, and Cytomegalovirus (CMV)-viral loads and virus-specific T-cell immunity in a 1-year prospective cohort of 27 HIV(+) kidney transplant recipients. While the results show an increasing breadth and magnitude of the herpesvirus-specific cytotoxic T-cell (CTL) response over-time, they also revealed a significant depletion of polyfunctional virus-specific CTL in individuals receiving thymoglobulin as a lymphocyte-depleting treatment. The disappearance of polyfunctional CTL was accompanied by virologic EBV-reactivation events, directly linking the absence of specific polyfunctional CTL to viral reactivation. The data provide first insights into the immune-reserve in HIV+ infected transplant recipients and highlight new immunological effects of thymoglobulin treatment. Long-term studies will be needed to assess the clinical risk associated with thymoglobulin treatment, in particular with regards to EBV-associated lymphoproliferative diseases.

AB In an endemic rural area of southeast Brazil, surveys confirmed that dogs serve as peridomestic reservoirs of Leishmania infantum. It is likely that the lack of efficient control is because presently used diagnostic tests miss positive dogs. Overall, 57% of the dogs had specific antibodies, but the canine infection was not uniformly fatal and many seropositive. dogs remained asymptomatic or even spontaneously recovered. Furthermore, 42% of the human residents became leishmanin-positive reactors and 47% had positive serology at the initial survey, but our estimates also point at a high recovery rate among the infected population with time. The delayed-type hypersensitivity (DTH) reaction to Leishmania was a good indicator of resistance to infection in this particular epidemiologic situation. The lack of any significant differences in infection rates by gender or age indicate that all of the population was at an equal risk of infection and most people were infected in the peridomestic setting.

AB Klippel-Feil syndrome is a visually arresting deformity wherein severe restriction of cervical motion predicts a difficult airway. Even minor distraction of the neck risks cervical spine or neurologic injury, so regional techniques, awake fiberoptic intubation, or awake tracheostomy are recommended anesthetic approaches. We present a case of aortic dissection in a Klippel-Feil syndrome patient for whom congenital bilateral deafness, coupled with the urgency of the surgery, mitigated against the recommended first-choice techniques. Using anesthesia crisis resource management methods, a multi-member team rehearsed predefined roles and then managed the airway via inhaled induction of anesthesia, followed by flexible fiberoptic intubation.

AB Objective: Subgroups of mild cognitive impairment (MCI) have been proposed, but few studies have investigated the nonamnestic, single-domain subgroup of MCI. The goal of the study was to compare clinical and neuroimaging characteristics of two single-domain MCI subgroups: amnestic MCI and dysexecutive MCI.
Methods: We compared the cognitive, functional, behavioral, and brain imaging characteristics of patients with amnestic MCI (n = 26), patients with dysexecutive MCI (n = 32), and age- and education-matched control subjects (n = 36) using analysis of variance and X 2 tests. We used voxel-based morphometry to examine group differences in brain magnetic resonance imaging atrophy patterns.
Results: Patients with dysexecutive MCI had significantly lower scores on the majority of executive function tests, increased behavioral symptoms, and left prefrontal cortex atrophy on magnetic resonance imaging when compared with control subjects. In contrast, patients with amnestic MCI had significantly lower scores on tests of memory and a pattern of atrophy including bilateral hippocampi and entorhinal cortex, right inferior parietal cortex, and posterior cingulate gyrus when compared with control subjects.
Interpretation: Overall, the clinical and neuroimaging findings provide support for two distinct single-domain subgroups of MCI., one involving executive function and the other involving memory. The brain imaging differences suggest that the two MCI subgroups have distinct patterns of brain atrophy. Ann Neurol 2009;65:414-423

AB Objective: To examine the influence of American Society of Anesthesiologists Physical Status Classification (ASA) and preoperative Functional Health Status (FHS) variables on risk-adjusted estimates of surgical quality and to assess whether classifications are inflated at some hospitals.
Background: ASA and FHS are influential in risk-adjusted comparisons of surgical quality. However, because ASA and FHS are subjective they can be inflated, making patients appear more ill than they actually are, and crediting hospitals for a sicker patient population.
Methods: We identified 28,75 1 colorectal surgery patients at 170 hospitals participating in the American College of Surgeon's National Surgical Quality Improvement Program (ACS NSQIP) during 2006 to 2007. Logistic regression models were developed for morbidity and mortality with and without inclusion of ASA and FHS. Hospital quality rankings from the different models were compared.
Results: Morbidity and mortality rates were 24.3% and 3.9%. respectively. Percents of patients in ASA classes I through V were 3.3%, 46.4%, 41.5%. 8.3%, and 0.7% and that were independent or partially or totally dependent were 89.2%, 7.2% and 3.6%, respectively. Models that included ASA and FHS exhibited slightly better fit (Hosmer-Lemshow statistic) and discrimination (c-statistic) than models without both these variables, though magnitudes of differences were consistent with chance. There was inconsistent evidence for improper assignment of ASA and FHS.
Conclusions: The small improvements in model quality when both ASA and FHS are present versus absent, suggest that they make a unique contribution to assessing severity of preoperative risk. With little indication that these subjective variables are subject to an important level of institutional bias, it is appropriate that they be used to assess risk-adjusted surgical quality. Periodic monitoring for inappropriate inflation of ASA status is warranted.

AB Background. At our institution, coronary artery bypass grafting (CABG) operations are performed by staff surgeons or by first- or second-year cardiothoracic residents under the direct supervision of attending surgeons. We evaluated the influence of surgical seniority on outcomes.
Methods. Using prospectively collected data from our departmental database, we identified all primary, isolated CABG operations (n = 1,042) performed between July 1997 and April 2007. Operations were then stratified according to the seniority of the primary surgeon: first-year cardiothoracic resident (CT1), second-year cardiothoracic resident (CT2), or staff surgeon. Data were examined for any association between seniority and surgical outcomes.
Results. Staff, CT2, and CT1 surgeons performed 47 (4%), 610 (59%), and 385 (37%) cases, respectively. Efficiency was correlated with experience: for CT1, CT2, and staff surgeons, respectively, operative times averaged 345, 313, and 302 minutes; perfusion times averaged 118, 106, and 96 minutes; and cross-clamp times averaged 68, 58, and 57 minutes (p < 0.05 for all comparisons). The incidences of major morbidity (10.1%, 12.3%, 12.8%) and operative mortality (0.8%, 1.5%, 2.1%) were similar after operations performed by CT1, CT2, and staff surgeons, respectively (p > 0.15 for all). In univariate and multivariate analyses, the seniority of the primary surgeon did not independently predict morbidity or perioperative mortality. On follow-up (mean, 1,485 +/- 1,015 days), there was no significant difference in patient survival (log-rank, p = 0.64).
Conclusions. Lower academic seniority was associated with longer CABG operative times but did not affect outcomes. Thus, training residents to perform CABG is safe and is characterized by progressive improvement in their technical efficiency.

AB Near-infrared spectroscopy (NIRS) is a noninvasive neuroimaging tool for studying evoked hemodynamic changes within the brain. By this technique, changes in the optical absorption of light are recorded over time and are used to estimate the functionally evoked changes in cerebral oxyhemoglobin and deoxyhemoglobin concentrations that result from local cerebral vascular and oxygen metabolic effects during brain activity. Over the past three decades this technology has continued to grow, and today NIRS studies have found many niche applications in the fields of psychology, physiology, and cerebral pathology. The growing popularity of this technique is in part associated with a lower cost and increased portability of NIRS equipment when compared with other imaging modalities, such as functional magnetic resonance imaging and positron emission tomography. With this increasing number of applications, new techniques for the processing, analysis, and interpretation of NIRS data are continually being developed. We review some of the time-series and functional analysis techniques that are currently used in NIRS studies, we describe the practical implementation of various signal processing techniques for removing physiological, instrumental, and motion-artifact noise from optical data, and we discuss the unique aspects of NIRS analysis in comparison with other brain imaging modalities. These methods are described within the context of the MATLAB-based graphical user interface program, HomER, which we have developed and distributed to facilitate the processing of optical functional brain data.

AB We developed a novel imaging technique that provides real-time two-dimensional maps of the absolute partial pressure of oxygen and relative cerebral blood flow in rats by combining phosphorescence lifetime imaging with laser speckle contrast imaging. Direct measurement of blood oxygenation based on phosphorescence lifetime is not significantly affected by changes in the optical parameters of the tissue during the experiment. The potential of the system as a novel tool for quantitative analysis of the dynamic delivery of oxygen to support brain metabolism was demonstrated in rats by imaging cortical responses to forepaw stimulation and the propagation of cortical spreading depression waves. This new instrument will enable further study of neurovascular coupling in normal and diseased brain. 0 2009 Optical Society of America

AB Objective: To study the safety and efficacy of topical bevacizumab in the treatment of corneal neovascularization (NV).
Design: In a prospective, open-label, noncomparative study, 10 eyes from 10 patients with stable corneal NV were treated with topical bevacizumab, 1.0%, for 3 weeks and followed up for up to 24 weeks.
Main Outcome Measures: The primary safety variables were the occurrence of ocular and systemic adverse events throughout the course of the study. The primary efficacy variables were neovascular area, the area of the corneal vessels themselves; vessel caliber, the mean diameter of the corneal vessels; and invasion area, the fraction of the total corneal area covered by the vessels.
Results: From baseline visit to the last follow-up visit, mean reductions were 47.1% (standard deviation [SD], 36.7%) for neovascular area, 54.1% (SD, 28.1%) for vessel caliber, and 12.2% (SD, 42.0%) for invasion area. The decreases in neovascular area and vessel caliber were statistically significant (P=.001 and P <.001, respectively). However, changes in invasion area did not achieve statistical significance (P=.19). Visual acuity and central corneal thickness showed no significant changes. Topical bevacizumab was well tolerated with no adverse events.
Conclusions: Short-term topical bevacizumab therapy reduces the severity of corneal NV without local or systemic adverse effects.
Application to Clinical Practice: Topical bevacizumab provides an alternative therapy in the treatment of stable corneal NV.

AB Objective: To examine the impact of clinical predictors (pretreatment variables) and other influences (treatment and posttreatment variables) on long-term quality of life (QOL) in patients treated for squamous cell carcinoma of the upper aerodigestive tract. We hypothesized that baseline QOL and comorbidity would be predictors of QOL 1 year after treatment.
Design: Retrospective cohort study.
Setting: Academic Medical Center in Seattle, Washington.
Patients: Patients (N=173) with baseline (pretreatment) and 1-year posttreatment QOL data.
Main Outcome Measure: Head and neck-specific QOL scores at 1 year after treatment (as measured by the University of Washington Quality of Life [UW-QOL] scale).
Results: We identified strong relationships between 1-year UW-QOL scores and baseline UW-QOL scores (correlation coefficient [Pearson r]=0.58; P<.001) and pretreatment comorbidity (as measured by the Adult Comorbidity Evaluation scale) (Spearman rho=0.23; P<.001). T stage and N stage were also predictive. Although not a predictive variable, the presence of a gastrostomy tube at 1 year also strongly influenced 1-year UW-QOL scores. Patients with gastrostomy tubes had UW-QOL scores 11.5 points worse than those without (P<.001), when a 7-point difference is considered clinically significant. In predictive multivariate regression models, pretreatment QOL scores, comorbidity, and T stage had the strongest prognostic impact on 1-year UW-QOL scores.
Conclusions: In bivariate analyses, the presence of a gastrostomy tube worsens UW-QOL scores at 1 year and requires further investigation. When considering predictive variables only, baseline QOL and comorbidity appear to have strong influences on posttreatment QOL and have greater impact than treatment modality. Greater attention to these baseline predictors should be given when counseling patients about long-term function after treatment.

AB Hirsh AT, Turner AP, Elide DM, Haselkorn JK. Prevalence and impact of pain in multiple sclerosis: physical and psychologic contributors. Arch Phys Med Rehabil 2009;90: 646-51.
Objective: To characterize the prevalence and impact of pain in veterans with multiple sclerosis (MS) and to assess their association with demographic, biologic, and psychologic variables.
Design: Cross-sectional cohort study linking computerized medical record information to mailed survey data.
Setting: Veterans Health Administration (VHA).
Participants: Sixty-four percent (2994/4685) of veterans with MS who received services in VRA and also returned Survey questionnaires.
Interventions: Not applicable.
Main Outcome Measures: Items assessing pain intensity, pain interference, and physical and mental health functioning.
Results: Ninety-two percent of participants reported bodily pain within the prior 4 weeks, with 69% of the total sample indicating pain of moderate or higher intensity. Eighty-five percent indicated that pain caused functional interference during the past 4 weeks, with 71% of the total sample reporting pain-related interference that was moderate or greater. No significant sex or race differences emerged for the pain indices. A significant but modest relationship between increasing age and pain interference emerged (r=.05, P<.01); however, age was not significantly related to pain intensity. Multivariate regression analyses identified pain intensity (beta=.73), physical health functioning (beta=-07), and mental health functioning (beta=-.13) variables as significant, unique contributors to the prediction of pain interference. The interaction of pain intensity and physical functioning was also significant but of minimal effect size (beta=-.03).
Conclusions: Pain is highly prevalent and causes substantial interference in the lives of veterans with MS. The functional impact of pain in veterans with MS is influenced by pain intensity, physical health, and emotional functioning. Clinical practice should take each of these domains into consideration and reflect a biopsychosocial conceptualization.

TI Contained Anastomotic Leaks After Colorectal Surgery Are We Too Slow to
Act?
SO ARCHIVES OF SURGERY
LA English
DT Article
ID GASTROINTESTINAL ANASTOMOSIS; CURATIVE RESECTION; CANCER; SURVIVAL
AB Hypothesis: Contained and free anastomotic leaks, which occur in a small percentage of patients after colorectal surgery, are different clinical entities and consequently should be managed differently.
Design: Retrospective medical record review.
Setting: Academic medical center.
Patients: Patients who underwent colectomy with primary anastomosis (N = 4019) between January 1, 1992, and December 13, 2004, were eligible for participation in the study. Fifty-eight patients (1.5%) with an anastomotic leak demonstrated by communication between the collection and the gastrointestinal tract were identified. Twenty-eight of the patients had free leaks and 30 had contained leaks.
Main Outcome Measures: Time to presentation, symptoms at presentation, rates of reexploration, and in-hospital mortality.
Results: Baseline characteristics, presenting symptoms, physical examination findings, and laboratory values were similar between patients with contained and free leaks. Almost all patients with free leaks were taken directly to the operating room, whereas those with contained leaks were initially more likely to be treated nonoperatively. However, 24 of the 28 patients with contained leaks (86%) ultimately required surgical intervention. Inhospital mortality was the same in both groups (18% in the contained leak group and 17% in the free leak group).
Conclusions: In patients with contained leaks who have documented communication between the abscess cavity and the bowel, there is no difference in the rate of operative management or morbidity and mortality when compared with those with free leaks. This finding suggests that the categorization of leaks as free or contained may not be justified and argues for early operative intervention even in patients with contained leaks.

AB Objective. Systemic lupus erythematosus (SLE) is the prototypical systemic autoimmune disorder, with complex etiology and a strong genetic component. Recently, gene products involved in the interferon pathway have been under intense investigation in terms of the pathogenesis of SLE. STAT-1 and STAT-4 are transcription factors that play key roles in the interferon and Th1 signaling pathways, making them attractive candidates for involvement in SLE susceptibility.
Methods. Fifty-six single-nucleotide polymorphisms (SNPs) across STAT1 and STAT4 on chromosome 2 were genotyped using the Illumina platform, as part of an extensive association study in a large collection of 9,923 lupus patients and control subjects from different racial groups. DNA samples were obtained from the peripheral blood of patients with SLE and control subjects. Principal components analyses and population-based case-control association analyses were performed, and the P values, false discovery rate q values, and odds ratios with 95% confidence intervals were calculated.
Results. We observed strong genetic associations with SLE and multiple SNPs located within STAT4 in different ethnic groups (Fisher's combined P = 7.02 x 10(-25)). In addition to strongly confirming the previously reported association in the third intronic region of this gene, we identified additional haplotypic association across STAT4 and, in particular, a common risk haplotype that is found in multiple racial groups. In contrast, only a relatively weak suggestive association was observed with STAT1, probably due to its proximity to STAT4.
Conclusion. Our findings indicate that STAT4 is likely to be a crucial component in SLE pathogenesis in multiple racial groups. Knowledge of the functional effects of this association, when they are revealed, might improve our understanding of the disease and provide new therapeutic targets.

AB Introduction/objectives: Cardiovascular disease is the leading cause of death for individuals with diabetes mellitus. Controversy exists regarding the screening of asymptomatic diabetics for occult coronary artery disease (CAD). The purpose of this study is to describe the prevalence of occult CAD in a group of asymptomatic subjects with diabetes using non-invasive coronary angiography, as well as to investigate the predictive accuracy of current guidelines with regards to their recommended criteria for further cardiac diagnostic testing in this patient population.
Methods: We prospectively enrolled 217 asymptomatic Korean outpatients with type 2 diabetes who had no prior history of CAD. All underwent non-invasive coronary angiography using a 64-slice multi-detector computed tomography scanner.
Results: The mean age of the study participants was 59 +/- 8 years; 66% were men. Diabetes duration was 7 +/- 7 years, mean Framingham risk score was 13%, and mean hemoglobin A1C level was 7%. Of the 217 outpatients, 138 (64%) had occult CAD based on cardiac computed tomography angiography (CCTA) findings. Thirty-six (36/138; 26%) had a significant stenosis on CCTA. Nearly half of the individuals (62/138; 45%) had a combination of non-calcifled and calcified plaques. Only 5 out of 217 (2%) individuals with significant stenosis would have been missed using the American Diabetes Association (ADA) criteria for further cardiac testing.
Conclusion: Almost two thirds of asymptomatic diabetics have occult CAD, including obstructive disease. Based on CCTA findings, the ADA criteria for further cardiac diagnostic testing would identify most individuals who have a significant coronary stenosis.

AB Across studies, paying attention to and analyzing one's emotions has been found to be both positively and negatively correlated with depression symptoms. One way of reconciling these seemingly contradictory findings is the possibility that attending to emotions in a skillful manner may help to reduce depression whereas attending to emotions with limited skill may be counterproductive. Dialectical behavior therapy (DBT) is a clinical intervention designed to foster adaptive awareness, expression, regulation, tolerance, and acceptance of emotions. Results of the present report come from a pilot study of a 16-week DBT-based skills training group for treatment-resistant major depressive disorder (MDD) as an adjunctive treatment to pharmacotherapy. Patients were randomized to treatment or a waitlist control group. A significant interaction revealed that increases in emotional processing were associated with decreases in depression symptoms in the DBT-based skills group; however, increases in emotional processing in the waitlist condition were associated with increases in depression. Results offer preliminary support for the idea that participating in DBT-based skills training may help individuals with treatment-resistant MDD to develop skills that facilitate processing emotions in a way that helps to reduce rather than exacerbate depression symptoms.

AB Lynch syndrome/Hereditary non-polyposis colorectal cancer is caused by inherited germline mutations in mismatch repair (MMR) genes, and accounts for 2-5% of colorectal cancers (CRC). It is characterized by Young onset CRC and an increased risk for gynaecologic, Urinary tract and gastrointestinal cancers. Family history evaluation is crucial in the early identification of individuals at risk for Lynch syndrome. Individuals whose family history includes multiple relatives with cancer, two or more primary cancers, or component tumours diagnosed at a young age, should undergo genetic evaluation for Lynch syndrome. Guidelines recommend initial evaluation of the tumour with immunohistochemistry or microsatellite instability testing followed by germline testing for mutations in MMR genes in those with abnormal results. Genetic test results can guide screening recommendations for patients and their families. However, results are not always conclusive and in such cases recommendations for cancer screening Should be individualized on the basis of personal and family history. (C) 2009 Elsevier Ltd.

AB PCR is widely employed as the initial DNA amplification step for genetic testing and cancer biomarker detection. However, a key limitation of PCR-based methods, including real-time PCR, is the inability to selectively amplify low levels of variant alleles in a wild-type allele background. As a result, downstream assays are limited in their ability to identify subtle genetic changes that can have a profound impact on clinical decision-making and outcome or that can serve as cancer biomarkers. We developed COLD-PCR (co-amplification at lower denaturation temperature-PCR) [Li, Wang, Mamon, Kulke, Berbeco and Makrigiorgos (2008) Nat. Med. 14, 579-584], a novel form of PCR that amplifies minority alleles selectively from mixtures of wild-type and mutation-containing sequences irrespective of the mutation type or position on the sequence. Consequently, COLD-PCR amplification from genomic DNA yields PCR products containing high-prevalence variant alleles that can be detected. Since PCR constitutes a ubiquitous initial step for almost all genetic analysis, COLD-PCR provides a general platform to improve the sensitivity of essentially all DNA-variation detection technologies including Sanger sequencing, pyrosequencing, single molecule sequencing, mutation scanning, mutation genotyping or methylation assays. COLD-PCR combined with real-time PCR provides a new approach to boost the capabilities of existing real-time mutation detection methods. we replaced regular PCR with COLD-PCR before sequencing or real-time mutation detection assays to improve mutation detection-sensitivity by up to 100-fold and identified novel p53/Kras/EGFR (epidermal growth factor receptor) mutations in heterogeneous cancer samples that were missed by all existing methods. For clinically relevant micro-deletions, COLD-PCR enabled exclusive amplification and isolation of the mutants. COLD-PCR is expected to have diverse applications in the fields of biomarker identification and tracing, genomic instability, infectious diseases, DNA methylation testing and prenatal identification of fetal alleles in maternal blood.

AB B-Raf(V600E), an oncogenic protein kinase, is the most frequent genetic alteration in papillary thyroid carcinomas (PTC). PTC represents 80-90% of all thyroid cancers and over the past five years, more than 200 manuscripts have been published about the relationship between "B-Raf(V600E) and thyroid cancer". B-Raf(V600E) genetically arises from a transversion point mutation (valine-to-glutamate substitution at amino acid residue-600, V600E) and leads to over activation of the mitogen-activated protein kinases (MAPK) signaling pathway. The MAPK pathway is essential for transmitting proliferation signals generated by cell surface receptors and cytoplasmic signaling elements to the nucleus. In many cancers, including thyroid cancer, B-Raf(V600E) appears to play a crucial role in cell proliferation, survival and de-differentiation. In thyroid cancer, the V600E mutation occurs with greater frequently in aggressive subtypes of PTC, and in individuals that present at advanced stages of disease with extra-thyroidal extension and/or lymph node metastases. B-Raf(V600E) is considered a marker of aggressive disease in both PTC (> 1 cm) and micro-PTC (<= 1 cm), and interestingly, is associated with both loss of I-131 avidity and PTC recurrence. Though treatment of patients with thyroid cancer is usually successful and most patients are rendered disease-free, to date there are no effective therapies for patients with invasive, non-radioiodine sensitive tumors or metastatic disease. In this article we will review the relation between B-Raf(V600E) and PTC, as well as both non-selective and selective pharmacological agents currently under investigation for treatment of B-Raf(V600E) positive PTC.

AB Background: Attention-deficit/hyperactivity disorder (ADHD) is defined as the most common neurobehavioral disorder of childhood, but an objective diagnostic test is not available yet to date. Neurophychological, neuroimaging, and neurophysiological research offer ample evidence of brain and behavioral dysfunctions in ADHD, but these findings have not been useful as a diagnostic test.
Methods: Whole-head magnetoencephalographic recordings were obtained from 14 diagnosed ADHD patients and 14 healthy children during resting conditions. Lempel-Ziv complexity(LZC) values were obtained for each channel and child and averaged in five sensor groups: anterior, central, left lateral, right lateral, and posterior.
Results: Lempel-Ziv complexity scores were significantly higher in control subjects, with the maximum value in anterior region. Combining age and anterior complexity values allowed the correct classification of ADHD patients and control subjects with a 93% sensitivity and 79% specificity. Control subjects showed an age-related monotonic increase of LZC scores in all sensor groups, while children with ADHD exhibited a nonsignificant tendency toward decreased LZC scores. The age-related divergence resulted in a 100% specificity in children older than 9 years.
Conclusions: Results support the role of a frontal hypoactivity in the diagnosis of ADHD. Moreover, the age-related divergence of complexity scores between ADHD patients and control subjects might reflect distinctive developmental trajectories. This interpretation of our results is in agreement with recent investigations reporting a delay of cortical maturation in the prefrontal cortex.

In this study, we report the effects of the presence of a plasticizing agent, namely vitamin E (alpha-tocopherol), in UHMWPE during high pressure crystallization. We found that this new vitamin E-blended and high pressure crystallized UHMWPE (VEHPE) has improved fatigue strength and wear resistance compared to virgin high pressure crystallized (HP) UHMWPE. This suggested different mechanisms of wear reduction and fatigue crack propagation resistance in UHMWPE. (C) 2008 Elsevier Ltd. All rights reserved.

AB This paper presents a robust method to conduct inference in finely stratified familial studies under proband-based sampling. We assume that the interest is in both the marginal effects of subject-specific covariates on a binary response and the familial aggregation of the response, as quantified by intrafamilial pairwise odds ratios. We adopt an estimating function for proband-based family studies originally developed by Zhao and others (1998) in the context of an unstratified design and treat the stratification effects as fixed nuisance parameters. Our method requires modeling only the first 2 joint moments of the observations and reduces by 2 orders of magnitude the bias induced by fitting the stratum-specific nuisance parameters. An analytical standard error estimator for the proposed estimator is also provided. The proposed approach is applied to a matched case-control familial study of sleep apnea. A simulation study confirms the usefulness of the approach.

AB Fatty liver disease is a problem of growing clinical importance due to its association with the increasingly prevalent conditions of obesity and diabetes. While steatosis represents a reversible state of excess intrahepatic lipid, it is also associated with increased susceptibility to oxidative and cytokine stresses and progression to irreversible hepatic injury characterized by steatohepatitis, cirrhosis, and malignancy. Currently, the molecular mechanisms underlying progression of this dynamic disease remain poorly understood, particularly at the level of transcriptional regulation. We recently constructed a library of stable monoclonal green fluorescent protein (GFP) reporter cells that enable transcriptional regulation to be studied dynamically in living cells. Here, we adapt the reporter cells to create a model of steatosis that will allow investigation of transcriptional dynamics associated with the development of steatosis and the response to subsequent "second hit" stresses. The reporter model recapitulates many cellular features of the human disease, including fatty acid uptake, intracellular triglyceride accumulation, increased reactive oxygen species accumulation, decreased mitochondrial membrane potential, increased susceptibility to apoptotic cytokine stresses, and decreased proliferation. Finally, to demonstrate the utility of the reporter cells for studying transcriptional regulation, we compared the transcriptional dynamics of nuclear factor kappa B (NF kappa B), heat shock response element (HSE), and glucocorticoid response element (GRE) in response to their classical inducers under lean and fatty conditions and found that intracellular lipid accumulation was associated with dose-dependent impairment of NF kappa B and HSE but not GRE activation. Thus, steatotic reporter cells represent an efficient model for studying transcriptional responses and have the potential to provide important insights into the progression of fatty liver disease.

AB Sensory neurons that innervate the skin provide critical information about physical contact between the organism and the environment, including information about potentially-damaging stimuli that give rise to the sensation of pain. These afferents also contribute to the maintenance of tissue homeostasis, inflammation and wound healing, while sensitization of sensory afferents after injury results in painful hypersensitivity and protective behavior. In contrast to the traditional view of primary afferent terminals as the sole site of sensory transduction, recent reports have lead to the intriguing idea that cells of the skin play an active role in the transduction of sensory stimuli. The search for molecules that transduce different types of sensory stimuli (mechanical, heat, chemical) at the axon terminal has yielded a wide range of potential effectors, many of which are expressed by keratinocytes as well as neurons. Emerging evidence underscores the importance of nucleotide signaling through P2X ionotropic and P2Y metabotropic receptors in pain processing, and implicates nucleotide signaling as a critical form of communication between cells of the skin, immune cells and sensory neurons. it is of great interest to determine whether pathological changes in these mechanisms contribute to chronic pain in human disease states such as complex regional pain syndrome (CRPS). This review discusses recent advances in our understanding of communication mechanisms between cells of the skin and sensory axons in the transduction of sensory input leading to pain.

AB Background: The relationship between nail and bone may be measurable, thus making the fingernail a potentially Valuable too] for assessing bone health for women receiving treatment for breast cancer. In the BIG 1-98 Fingernail Pilot Substudy, Bone Quality Test (BQT) scores of fingernails were measured at two assessment timepoints.
Methods: Thirteen eligible patients were enrolled into the substudy during their treatment with tamoxifen (four patients) or letrozole (nine patients). Two fingernails were tested and BQT Scores averaged for two assessments six months apart.
Results: BQT scores collected six months later (second assessment) significantly decreased compared with those at first collection (p = 0.007) regardless of treatment and prior fracture.
Conclusion: The reduction of BQT scores observed in the patients of our small exploratory study during exposure to bone-altering breast cancer treatments is an incentive for larger studies using this technique. (C) 2009 Elsevier Ltd. All rights reserved.

AB Waldenstrom Macroglobulinemia (WM) is a B-cell malignancy characterized by excess bone marrow (BM) lymphoplasmacytic cells (LPC). The accumulation of LPC in WM may represent a failure of B-cells to properly differentiate into plasma cells. The present study investigated transcriptional expression of genes involved in late B-cell differentiation, including PRDM1, PAX5, XBP1 transcripts and ERN1, in BM B-cells from 31 patients with WM and six healthy donors. Real time reverse transcription polymerase chain reaction (RT-PCR) determined that approximately 80% of the patients had high XBP1 spliced mRNA expression, 80% of whom had high mRNA ERN1 alpha expression. XBP1, PRDM1 and PAX5 mRNA was present in all patients studied. Using relative quantitative RT-PCR we isolated two groups with low and high expression of XBP1, XBP1 spliced and ERN1 alpha. Sequence analysis showed germline polymorphisms in all genes studied. These data depict for the first time a heterogeneous expression pattern of the genes involved in late differentiation process of plasma cells in patients with WM and propose a role of XBP1-ERN1 alpha in WM pathogenesis.

AB BACKGROUND: Despite the rise in publicly available cancer information, little is known about the association between patient information seeking and the adoption of cancer technologies. The authors of this report investigated the relation between patient information seeking and awareness about and receipt of novel targeted therapy (TT) for colon cancer among patients for whom therapy is approved by the US Food and Drug Administration (FDA) and among patients for whom therapy is not FDA approved. METHODS: A retrospective, population-based survey of 633 colon cancer patients were identified through the Pennsylvania Cancer Registry. Outcome measures were self-reported awareness about and receipt of TT (bevacizumab and cetuximab). RESULTS: After adjusting for sociodemographic characteristics, high levels of treatment information seeking were associated strongly with hearing about TT (odds ratio [OR], 2.83; 95% confidence interval [CI], 1.49-5.38) and receiving TT (OR, 3.22; 95% Cl, 1.36-7.62). These associations were present for patients with metastatic disease, for whom the use of TT is FDA approved, and for patients with localized disease, for whom the use of TT is not FDA approved (P for interactions = .29). Internet use (OR, 2.88; 95% CI, 1.40-5,94) and newspaper/magazine use (OR, 3.44; 95% CI, 1.34-8.84) were associated with hearing about TT. Seeking information from nontreating physicians was associated with hearing about TT (OR, 1.95; 95% CI, 1.03-3.68) and receiving TT (OR, 2.64; 95% Cl, 1.16-5.97). CONCLUSIONS: Patient information seeking was related to the adoption of TT for colon cancer in both appropriate and inappropriate clinical settings. These findings emphasize the importance of exploring patient influence on physician prescribing patterns and understanding the impact of information seeking on cancer outcomes.

AB Both homoharringtonine (HHT), an alkaloid derivative from the Chinese yew tree that inhibits protein synthesis, and low-dose cytarabine have independent activity in CML and have been used in combination after failure of interferon therapy.
The CALGB performed a phase II trial of HHT (2.5 mg/m(2) per day) plus cytarabine (7.5 mg/m(2) per day), given together via continuous intravenous infusion for 7 days in previously untreated patients with Ph chromosome positive chronic phase CML. HHT/cytarabine cycles were repeated every 28 days if the blood counts were adequate. The primary endpoint was the major cytogenetic response rate after 9 months.
Forty of the 44 enrolled patients required reduction in the infusion duration during at least one cycle. Myelosuppression was common; 66% developed neutrophil count < 500/mu l, but grade 3 infections occurred in only 7%. Thirty-six of 44 patients (82%) achieved a complete hematologic remission; the median duration has not been reached. Only 4 of the 23 patients (17%) having adequate cytogenetic response assessment achieved a major response within nine cycles.
Although HHT/cytarabine was generally well tolerated, the cytogenetic response rate did not exceed the level previously seen in patients with interferon-refractory CML and was not nearly as high as associated with imatinib in newly diagnosed patients.

AB Purpose: Patients with early-onset breast and/or ovarian cancer frequently wish to know if they inherited a mutation in one of the cancer susceptibility genes, BRCA1 or BRCA2. Accurate carrier prediction models are needed to target costly testing. Two widely used models, BRCAPRO and BOADICEA, were developed using data from non-Hispanic Whites (NHW), but their accuracies have not been evaluated in other racial/ethnic populations.
Methods: We evaluated the BRCAPRO and BOADICEA models in a population-based series of African American, Hispanic, and NHW breast cancer patients tested for BRCA1 and BRCA2 mutations. We assessed model calibration by evaluating observed versus predicted mutations and attribute diagrams, and model discrimination using areas under the receiver operating characteristic curves.
Results: Both models were well-calibrated within each racial/ethnic group, with some exceptions. BOADICEA overpredicted mutations in African Americans and older NHWs, and BRCAPRO underpredicted in Hispanics. In all racial/ethnic groups, the models overpredicted in cases whose personal and family histories indicated >80% probability of carriage. The two models showed similar discrimination in each racial/ethnic group, discriminating least well in Hispanics. For example, BRCAPRO's areas under the receiver operating characteristic curves were 83% (95% confidence interval, 63-93%) for NHWs, compared with 74% (59-85%) for African Americans and 58% (45-70%) for Hispanics.
Conclusions: The poor performance of the model for Hispanics may be due to model misspecification in this racial/ethnic group. However, it may also reflect racial/ ethnic differences in the distributions of personal and family histories among breast cancer cases in the Northern California population.

AB Background: Lung cancer is the most common cause of cancer-related mortality. Smoking cessation is crucial to decrease risk, but additional prevention modalities are needed. The use of nonsteroidal anti-inflammatory drugs (NSAID) may be promising.
Methods: The study was a prospective cohort of 77,125 men and women, ages 50 to 76 years, from Washington state recruited in 2000 to 2002 (the VITamin And Lifestyle study). Lung cancer cases were identified through the Seattle-Puget Sound Surveillance, Epidemiology and End Results cancer registry during 5 years of follow-up. Hazard ratios (HR) associated with 10-year average use of total NSAIDs (excluding low-dose aspirin) and specific categories of NSAIDs were calculated for total incident lung cancer and specific morphologies.
Results: A total of 665 lung cancer cases were identified. After adjusting for smoking, age, gender, and acetaminophen use, there was a borderline-significant inverse trend with total NSAID use [>4.2 d/wk for >10 years versus none: HR, 0.82; 95% confidence interval (95% CI), 0.64-1.04; P for trend = 0.051. The association was strongest for adenocarcinoma (HR, 0.59; 95% CI, 0.37-0.94; P for trend = 0.01) and seemed to be limited to men (HR, 0.66; 95% CI, 0.47-0.92; P for trend = 0.01) and to long-term (>= 10 years) former smokers (HR, 0.65; 95% CI, 0.44-0.96; P for trend = 0.04). There were no appreciable differences by NSAID type.
Conclusions: Total NSAID use was associated with a small reduced risk of lung cancer, which was strongest for adenocarcinoma, men, and long-term former smokers. These findings are supported by known lung carcinogenesis mechanisms and suggest that NSAIDS may be useful for chemoprevention. (Cancer Epidemiol Biomarkers Prev 2009;18(4):1203-7)

TI Race and Time from Diagnosis to Radical Prostatectomy: Does Equal Access
Mean Equal Timely Access to the Operating Room?-Results from the SEARCH
Database

UNITED-STATES; HEALTH-CARE; CANCER; IMPACT; DELAY; RISK; EPIDEMIOLOGY
AB Background: African American men with prostate cancer are at higher risk for cancer-specific death than Caucasian men. We determine whether significant delays in management contribute to this disparity. We hypothesize that in an equal-access health care system, time interval from diagnosis to treatment would not differ by race.
Methods: We identified 1,532 African American and Caucasian men who underwent radical prostatectomy (RP) from 1.988 to 2007 at one of four Veterans Affairs Medical Centers that comprise the Shared Equal-Access Regional Cancer Hospital (SEARCH) database with known biopsy date. We compared time from biopsy to RP between racial groups using linear regression adjusting for demographic and clinical variables. We analyzed risk of potential clinically relevant delays by determining odds of delays >90 and >180 days.
Results: Median time interval from diagnosis to RP was 76 and 68 days for African Americans and Caucasian men, respectively (P = 0.004). After controlling for demographic and clinical variables, race was not associated with the time interval between diagnosis and RP (P = 0.09). Furthermore, race was not associated with increased risk of delays >90 (P = 0.45) or >180 days (P = 0.31).
Conclusions: In a cohort of men undergoing RP in an equal-access setting, there was no significant difference between racial groups with regard to time interval from diagnosis to RP. Thus, equal-access includes equal timely access to the operating room. Given our previous finding of poorer outcomes among African Americans, treatment delays do not seem to explain these observations. Our findings need to be confirmed in patients electing other treatment modalities and in other practice settings. (Cancer Epiderniol Biomarkers Prev 2009;18(4):1208-12)

AB Background: Direct-to-consumer (DTC) BRCA testing may expand access to genetic testing and enhance cancer prevention efforts. It is not known, however, if current DTC websites provide adequate risk information for informed medical decision making.
Methods: A total of 284 women with a personal or family history of breast/ovarian cancer were randomly assigned to view a "mock" DTC commercial website [control condition (CC); n = 93] or the same "mock" website that included information on the potential risks of obtaining genetic testing online. Risk information was framed two ways: risk information attributed to expert sources (ES; n = 98) and unattributed risk information (URI; it = 93). Participants completed an online survey. End points were intentions to get BRCA testing, testing site preference, and beliefs about DTC BRCA testing.
Results: The sample was 82% white, had a mean age of 39 years (range, 18-70 years) and had a mean education of 3 years of college. Women exposed to risk information had lower intentions to get BRCA testing than women in the CC [adjusted odds ratio (OR), 0.48; 95% confidence interval (95% CI) 0.26-0.87; P = 0.016], and less positive beliefs about online BRCA testing (adjusted OR, 0.48; 95% CI, 0.27-0.86; P = 0.014). Women in the ES condition were more likely to prefer clinic-based testing than were women in the CC (adjusted OR, 2.05; 95% CI, 1.07-3.90; P = 0.030).
Conclusion: Exposing women to information on the potential risks of online BRCA testing altered their intentions, beliefs, and preferences for BRCA testing. Policy makers may want to consider the content and framing of risk information on DTC websites as they formulate regulation for this rapidly growing industry.

AB hrR3 is an oncolytic herpes simplex virus 1 (HSV-1) mutant that replicates preferentially in tumors compared with normal tissues. Portal venous administration of hrR3 in mice bearing diffuse colorectal carcinoma liver metastases significantly reduces tumor burden and prolongs animal survival. In this study, we compared survival benefit and biodistribution of hrR3 following intravenous (i.v.) administration versus intraperitoneal (i.p.) administration in immunocompetent mice bearing colon carcinoma peritoneal metastases. Mice bearing peritoneal metastases received 1 x 10(8) plaque-forming units hrR3 or mock-infected media every other day for three doses and were randomized to have the viruses administered by either an i.p. or i.v. route. Biodistribution was assessed by PCR amplification of HSV-1-specific sequences from tumor and normal tissues including the small bowel, liver, spleen, kidney, lung, heart and brain. LD(50) for i.p. administration was compared with the LD(50) for i.v. administration. In subsequent experiments, animals were monitored for survival. The frequency of HSV-1 detection in peritoneal tumors was similar in mice randomized to either i.p. or i.v. administration. However, i.p. administration resulted in a more restricted systemic biodistribution, with a reduced frequency of virus detected in the kidney, lung and heart. The LD(50) associated with i.p. administration was higher than that with i.v. administration. Tumor burden was more effectively reduced with i.p. compared with i.v. administration. Median survival following i.p. administration was approximately twice that observed with i.v. administration. I. p. administration of an HSV-1 oncolytic mutant is associated with a more restricted biodistribution, less toxicity and greater efficacy against peritoneal metastases compared with i.v. administration.

AB TNFerade is a radioinducible adenoviral vector expressing tumor necrosis factor-alpha (TNF-alpha) (Ad.Egr-TNF) currently in a phase III trial for inoperable pancreatic cancer. We studied B16-F1 melanoma tumors in TNF receptor wild-type (C57BL/6) and deficient (TNFR1,2-/- and TNFR1-/-) mice. Ad.Egr-TNF+IR inhibited tumor growth compared with IR in C57BL/6 but not in receptor-deficient mice. Tumors resistant to TNF-alpha were also sensitive to Ad.Egr-TNF+IR in C57BL/6 mice. Ad.Egr-TNF+IR produced an increase in tumor-associated endothelial cell apoptosis not observed in receptor-deficient animals. Also, B16-F1 tumors in mice with germline deletions of TNFR1,2, TNFR1 or TNF-alpha, or in mice receiving anti-TNF-alpha exhibited radiosensitivity. These results show that tumor-associated endothelium is the principal target for Ad.Egr-TNF radiosensitization and implicate TNF-alpha signaling in tumor radiosensitivity.

AB The Adenoma Prevention with Celecoxib Trial examined the efficacy and safety of the cyclooxygenase (Cox)-2 inhibitor, celecoxib, for sporadic colorectal adenoma prevention in patients at high risk for colorectal cancer. The trial randomized 2,035 subjects to receive either placebo, celecoxib 200 mg twice daily, or celecoxib 400 mg twice daily. The primary study safety and efficacy analyses involved 3 years of treatment. The results showed significant antitumor effect but also indicated increased cardiovascular adverse events in patients treated with celecoxib compared with placebo. A total of 933 patients participated in an extension of the Adenoma Prevention with Celecoxib Trial, with a planned total treatment and surveillance duration of 5 years. Study medication was stopped early, resulting in a median treatment duration of 3.1 years for those with a year 5 colonoscopy. Patients treated on the placebo arm had a cumulative adenoma incidence of 68.4% over 5 years of observation. This figure was 59.0% (P < 0.0001) for those receiving low-dose celecoxib, and 60.1% (P < 0.0001) for those receiving high-dose celecoxib. The cumulative incidence of advanced adenomas over 5 years was 21.3% of those taking placebo, 12.5% (P < 0.0001) of those taking low dose celecoxib and 15.8% (P < 0.0001) of those taking high-dose celecoxib. Investigator reported treatment emergent adverse events were similar across all treatment groups for categories including renal and hypertensive events and gastrointestinal ulceration and hemorrhage events. For a category composed of cardiovascular and thrombotic events, the risk relative to placebo was 1.6 (95% confidence interval, 1.0, 2.5) for those using 200 mg twice daily celecoxib and 1.9 (95% confidence interval, 1.2, 3.1) for those using 400 mg twice daily celecoxib. Secondary analysis showed an interaction between a baseline history of atherosclerotic heart disease and study drug use with respect to cardiovascular and thrombotic adverse events (P = 0.004). These results confirm the inhibitory effect of celecoxib on colorectal adenoma formation, and provide additional safety data indicating an elevated risk for cardiovascular and thrombotic adverse events, particularly for patients with preexisting atherosclerotic heart disease.

AB Non-small cell lung cancer (NSCLC) has a poor prognosis, with substantial mortality rates even among patients diagnosed with early-stage disease. There are few effective measures to block the development or progression of NSCLC. Antiangiogenic drugs represent a new class of agents targeting multiple aspects of tumor progression, including cell proliferation, invasion, migration, and outgrowth of metastatic deposits. We tested the multitargeted angiogenesis inhibitor sunitinib in a novel endogenous mouse model of NSCLC, which expresses a conditional activating mutation in Kras with or without conditional deletion of Lkb1; both alterations are frequent in human NSCLC. We showed that daily treatment with sunitinib reduced tumor size, caused tumor necrosis, blocked tumor progression, and prolonged median survival in both the metastatic (Lkb1/Kras) and nonmetastatic (Kras) mouse models; median survival was not reached in the nonmetastatic model after 1 year. However, the incidence of local and distant metastases was similar in sunitinib-treated and untreated Lkb1/Kras mice, suggesting that prolonged survival with sunitinib in these mice was due to direct effects on primary tumor growth rather than to inhibition of metastatic progression. These collective results suggest that the use of angiogenesis inhibitors in early-stage disease for prevention of tumor development and growth may have major survival benefits in the setting of NSCLC.

AB Lymphatic metastasis is a critical determinant of cancer prognosis. Recently, several lymphangiogenic molecules such as vascular endothelial growth factor (VEGF)-C and VEGF-D were identified. However, the mechanistic understanding of lymphatic metastasis is still in infancy. Nitric oxide (NO) plays a crucial role in regulating blood vessel growth and function as well as lymphatic vessel function. NO synthase (NOS) expression correlates with lymphatic metastasis. However, causal relationship between NOS and lymphatic metastasis has not been documented. To this end, we first show that both VEGF receptor-2 and VEGF receptor-3 stimulation activate eNOS in lymphatic endothelial cells and that NO donors induce proliferation and/or survival of cultured lymphatic endothelial cells in a dose-dependent manner. We find that an NOS inhibitor, L-NMMA, blocked regeneration of lymphatic vessels. Using intravital microscopy that allows us to visualize the steps of lymphatic metastasis, we show that genetic deletion of eNOS as well as NOS blockade attenuates peritumor lymphatic hyperplasia of VEGF-C-overexpressing T241 fibrosarcomas and decreases the delivery of metastatic tumor cells to the draining lymph nodes. Genetic deletion of eNOS in the host also leads to a decrease in T241 tumor cell dissemination to the lymph nodes and macroscopic lymph node metastasis of B16F10 melanoma. These findings indicate that eNOS mediates VEGF-C-induced lymphangiogenesis and, consequently, plays a critical role in lymphatic metastasis. Our findings explain the correlation between NOS and lymphatic metastasis seen in a number of human tumors and open the door for potential therapies exploiting NO signaling to treat diseases of the lymphatic system.

AB The Mucin 1 (MUC1) oncoprotein is aberrantly overexpressed in diverse human malignancies including breast and lung cancer. Although MUC1 modulates the activity of several transcription factors, there is no information regarding the effects of MUC1 on global gene expression patterns and the potential role of MUC1-induced genes in predicting outcome for cancer patients. We have developed an experimental model of MUC1-induced transformation that has identified the activation of gene families involved in oncogenesis, angiogenesis, and extracellular matrix remodeling. A set of experimentally derived MUC1-induced genes associated with tumorigenesis was applied to the analysis of breast and lung adenocarcinoma cancer databases. A 35-gene MUC1-induced tumorigenesis signature predicts significant decreases in both disease-free and overall survival in patients Kith breast (n = 295) and lung (n = 442) cancers. The data show that the MUC1 oncoprotein contributes to the regulation of genes that are highly predictive of clinical outcome in breast and lung cancer patients. [Cancer Res 2009;69(7):2833-7]

AB Extracellular signal-regulated kinase (ERR)/mitogen-activated protein kinase pathway activity is regulated by the antagonist function of activating kinases and inactivating protein phosphatases. Sustained ERK pathway activity is commonly observed in human malignancies; however, the mechanisms by which the pathway is protected from phosphatase-mediated inactivation in the tumor tissue remain obscure. Here, we show that methylesterase PME-1-mediated inhibition of the protein phosphatase 2A promotes basal ERK pathway activity and is required for efficient growth factor response. Mechanistically, PME-1 is shown to support ERK pathway signaling upstream of Raf, but downstream of growth factor receptors and protein kinase C. In malignant gliomas, PME-1 expression levels correlate with both ERR activity and cell proliferation in vivo. Moreover, PME-1 expression significantly correlates with disease progression in human astrocytic gliomas (n = 222). Together, these observations identify PME-1 expression as one mechanism by which ERK pathway activity is maintained in cancer cells and suggest an important functional role for PME-1 in the disease progression of human astrocytic gliomas.

AB NOTCH signaling is deregulated in the majority of T-cell acute lymphoblastic leukemias (T-ALL) as a result of activating mutations in NOTCH1. Gamma secretase inhibitors (GSI) block proteolytic activation of NOTCH receptors and may provide a targeted therapy for T-ALL. We have investigated the mechanisms of GSI sensitivity across a panel of T-ALL cell lines, yielding an approach for patient stratification based on pathway activity and also providing a rational combination strategy for enhanced response to GSI. Whereas the NOTCH1 mutation status does not serve as a predictor of GSI sensitivity, a gene expression signature of NOTCH pathway activity does correlate with response, and may be useful in the selection of patients more likely to respond to GSI. Furthermore, inhibition of the NOTCH pathway activity signature correlates with the induction of the cyclin-dependent kinase inhibitors CDKN2D (p19(INK4d)) and CDKN1B (p27(Kip1)), leading to derepression of RB and subsequent exit from the cell cycle. Consistent with this evidence of cell cycle exit, short-term exposure of GSI resulted in sustained molecular and phenotypic effects after withdrawal of the compound. Combination treatment with GSI and a small molecule inhibitor of CDK4 produced synergistic growth inhibition, providing evidence that GSI engagement of the CDK4/RB pathway is an important mechanism of GSI action and supports further investigation of this combination for improved efficacy in treating T-ALL.

AB The androgen receptor (AR) directs diverse biological processes through interaction with coregulators such as AR trapped clone-27 (ART-27). Our results show that ART-27 is recruited to AR-binding sites by chromatin immunoprecipitation analysis. In addition, the effect of ART-27 on genome-wide transcription was examined. The studies indicate that loss of ART-27 enhances expression of many androgen-regulated genes, suggesting that ART-27 inhibits gene expression. Surprisingly, classes of genes that are up-regulated upon ART-27 depletion include regulators of DNA damage checkpoint and cell cycle progression, suggesting that ART-27 functions to keep expression levels of these genes low. Consistent with this idea, stable reduction of ART-27 by short-hairpin RNA enhances LNCaP cell proliferation compared with control cells. The effect of ART-27 loss was also examined in response to the antiandrogen bicalutamide. Unexpectedly, cells treated with ART-27 siRNA no longer exhibited gene repression in response to bicalutamide. To examine ART-27 loss in prostate cancer progression, immunohistochemistry was conducted on a tissue array containing samples from primary tumors of individuals who were clinically followed and later shown to have either recurrent or nonrecurrent disease. Comparison of ART-27 and AR staining indicated that nuclear ART-27 expression was lost in the majority of AR-positive recurrent prostate cancers. Our studies show that reduction of ART-27 protein levels in prostate cancer may facilitate antiandrogen-resistant disease. [Cancer Res 2009;69(7):3140-7]

AB Stroke remains a major health problem worldwide, and is the leading cause of serious long-term disability. Recent findings now suggest that strategies to enhance angiogenesis after focal cerebral ischemia may provide unique opportunities to improve clinical outcomes during stroke recovery. In this mini-review, we survey emerging mechanisms and potential targets for angiogenic therapies in brain after stroke. Multiple elements may be involved, including growth factors, adhesion molecules and progenitor cells. Furthermore, cross talk between angiogenesis and neurogenesis may also provide additional substrates for plasticity and remodeling in the recovering brain. A better understanding of the molecular interplay between all these complex pathways may lead to novel therapeutic avenues for tackling this difficult disease.

DE glioma; angiogenesis; anti-angiogenesis therapy; siRNA; miRNA;

AB Brain tumors exhibit marked and aberrant blood vessel formation indicating angiogenic endothelial cells as a potential target for brain tumor treatment. The brain tumor blood vessels are used for nutrient delivery, and possibly for cancer cell migration. The process of angiogenesis is complex and involves multiple players. The current angiogenesis inhibitors used in clinical trials mostly target single angiogenic proteins and so far show limited effects on tumor growth. Besides the conventional angiogenesis inhibitors, RNA-based inhibitors such as small-interfering RNAs (siRNAs) are being analyzed for their capacity to silence the message of proteins involved in neovascularization. More recently, a new family of non-coding RNAs, named angiomirs [microRNAs (miRNAs) involved in angiogenesis] has emerged. These small RNAs have the advantage over siRNAs in that they have the potential of silencing multiple messages at the same time and therefore they might become therapeutically relevant in a "one-hit multiple-target" context against brain tumor angiogenesis. In this review we will discuss the emerging technologies in anti-angiogenesis emphasizing on RNA-based therapeutics.

AB The stringent regulation of hematopoietic stem cell (HSC) quiescence versus cell cycle progression is essential for the preservation of a pool of long-term self-renewing cells and vital for sustaining an adequate supply of all blood lineages throughout life. Cell growth, the process that is mass increase, serves as a trigger for cell cycle progression and is regulated predominantly by mammalian target of rapamycin complex 1 (mTORC1) signaling. Emerging data from various mice models show deletion of several mTORC1 negative regulators, including PTEN, TSC1, PML and Fbxw7 result in similar HSC phenotypes characterized as HSC hyper-proliferation and subsequent exhaustion, and defective repopulating potential. Further pharmacological approaches show that PTEN, TSC1 and PML regulate HSC maintenance through mTORC1. mTORC1-mediated cell growth regulatory circuits thus play a critical role in the regulation of HSC quiescence.

AB IEX-1 (Immediate Early response gene X-1) is a stress-inducible gene. It suppresses production of reactive oxygen species (ROS) and protects cells from apoptosis induced by a wide range of stimuli, but the underlying mechanism is not known. This study reveals that IEX-1 targets the mitochondrial F1Fo-ATPase Inhibitor (IF1) for degradation, resulting in acceleration of ATP hydrolysis, concomitant with reduction in ROS production. A prominent role for IF1 degradation in the function of IEX-1 was corroborated by siRNA- mediated gene silencing of IF1 that recapitulated the effects of IEX-1 on ATP hydrolysis and ROS production. Moreover, progressive C-terminal truncation studies demonstrated that IEX-1 interacted with the C terminus of IF1 and the interaction might render IF1 prone to degradation by an as yet unidentified mitochondrial protease. In support of a physiological importance of IEX-1 in the modulation of IF1 expression, gene-targeted deletion of IEX-1 stabilized IF1 and reduced mitochondrial F1Fo-ATPase activity in vivo. The altered activity of the F1Fo enzyme may account for a metabolic switch from oxidative phosphorylation toward glycolysis in IEX-1 deficient cells. Thus, IEX-1 deficient cells were more susceptible to glucose deprivation than wild type counterparts and displayed increased glucose uptake and lactate production in hypoxic conditions. The cells were also relatively refractory to oligomycin-mediated inhibition of ATP production. The studies offer novel insights into the primary role of IEX-1 in regulating a balance between energy provision and ROS production.

AB The detection of cell cycle proteins in Alzheimer's disease (AD) brains may represent an early event leading to neurodegeneration. To identify cell cycle modifiers with anti-A beta properties, we assessed the effect of Differentiation-Inducing Factor-1 (DIF-1), a unique. small-molecule from Dictyostelium discoideum, on the proteolysis of the amyloid beta-protein precursor (APP) in a variety of different cell types. We show that DIF-1 slows cell cycle progression through G0/G1 that correlates with a reduction in cyclin D1 protein levels. Western blot analysis of DIF-treated cells and conditioned medium revealed decreases in the levels of secreted APP, mature APP, and C-terminal fragments. Assessment of conditioned media by sandwich ELISA showed reduced levels of A beta 40 and A beta 42, also demonstrating that treatment with DIF-1 effectively decreases the ratio of A beta 42 to A beta 40. In addition, DIF-1 significantly diminished APP phosphorylation at residue T668. Interestingly, site-directed mutagenesis of APP residue Thr668 to alanine or glutamic acid abolished the effect of DIF-1 on APP proteolysis and restored secreted levels of A beta. Finally, DIF-1 prevented the accumulation of APP C-terminal fragments induced by the proteasome inhibitor lactacystin, and calpain inhibitor N-acetyl-leucyl-leucyl-norleucinal (ALLN). Our findings suggest that DIF-1 affects G0/G1 -associated amyloidogenic processing of APP by a gamma-secretase-, proteasome- and calpain-insensitive pathway, and that this effect requires the presence of residue Thr668.

AB Experimental and imaging studies in monkeys have outlined various long association fiber bundles within the temporoparietal region. In the present study the trajectory of the middle longitudinal fascicle (MdLF) has been delineated in 4 human subjects using diffusion tensor magnetic resonance imaging segmentation and tractography. The MdLF seems to extend from the inferior parietal lobule (IPL), specifically the angular gyrus, to the temporal pole remaining within the white matter of the superior temporal gyrus (STG). Comparison of the superior longitudinal fascicle II-arcuate fascicle (SLF II-AF) with the MdLF in the same subjects revealed that MdLF is located in a medial and caudal position relative to SLF II-AF and that it extends more rostrally. Given the location of MdLF between the IPL (angular gyrus) and the STG, it is suggested that MdLF could have a role in language and attention functions.

AB The growing literature shows the pervasiveness and importance of comorbidity in youth with bipolar disorder (BPD). For instance, up to 90% of youth with BPD have been described to manifest comorbidity with attention-deficit hyperactivity disorder. Multiple anxiety, substance use, and disruptive behavior disorders are the other most commonly reported comorbidities with BPD. Moreover, important recent data highlight the importance of obsessive-compulsive and pervasive developmental illness in the context of BPD. Data suggest that not only special developmental relationships are operant in the context of comorbidity but also that the presence of comorbid disorders with BPD results in a more severe clinical condition. Moreover, the presence of comorbidity has therapeutic implications for the treatment response for both BPD and the associated comorbid disorder. Future longitudinal studies to address the relationship and the impact of comorbid disorders on course and therapeutic response over time are required in youth with BPD.

AB The risk of bipolar disorder (BPD) (15-42%) in first-degree relatives of children with BPD are consistently larger than the 8.7% estimate of recurrence risk of BPD in first-degree relatives of adult BPD cases. There have been no family linkage studies of pediatric BPD, but secondary analyses of adult linkage samples suggest that early-onset BPD both increases the strength of associations in linkage studies. Positive associations with pediatric BPD and the BDNF gene (VaII66), the GAD1 gene (4s2241165), and the dopamine transporter gene (rs41084) have been reported but none of these associations have been replicated in independent samples. The number of informative families examined so far is quite small and studies were vastly underpowered to detect small effects. An adequately powered sample will likely require collaborative ascertainment of cases and families from multiple sites using valid and accepted measures of pediatric BPD.

AB There has been growing interest in the use of complementary and alternative treatments in pediatric bipolar disorder (BPD). There are limited data, however, regarding the safety and efficacy of these treatments. This article discusses select complementary and alternative treatments that have been considered for use in pediatric BPD and/or depression, including omega-3-fatty acids, inositol, St. John's wort, SAMe, melatonin, lecithin, and acupuncture. Background information, reference to available adult and pediatric data, proposed mechanisms of action, dosing, side effects, and precautions of these treatments are included. Across the board, more research is necessary and warranted regarding the long-term safety and efficacy of available complementary and alternative treatments for the management of pediatric BPD.

TI Atrial Fibrillation Ablation Strategies for Paroxysmal Patients
Randomized Comparison Between Different Techniques
SO CIRCULATION-ARRHYTHMIA AND ELECTROPHYSIOLOGY

ID VEIN ANTRUM ISOLATION; PULMONARY VEINS; CATHETER ABLATION; INSIGHTS
AB Background-Whether different ablation strategies affect paroxysmal atrial fibrillation (AF) long-term freedom from AF/atrial tachyarrhythmia is unclear. We sought to compare the effect of 3 different ablation approaches on the long-term success in patients with paroxysmal AF
Methods and Results-One hundred three consecutive patients with paroxysmal AF scheduled for ablation and presenting in the electrophysiology laboratory in AF were selected for this study. Patients were randomized to pulmonary vein antrum isolation (PVAI; n=35) versus biatrial ablation of the complex fractionated atrial electrograms (CFEs; n=34) versus PVAI followed by CFAEs (n=34). Patients were given event recorders and followed up at 3, 6, 9, 12, and 15 months postablation. There was no statistical significant difference between the groups in term of sex, age, AF duration, left atrial size, and ejection fraction. At I year follow-up, freedom from AF/atrial tachyarrhythmia was documented in 89% of patients in the PVAI group, 91% in the PVAI plus CFAEs group, and 23% in the CFAEs group (P<0.001) after a single procedure and with antiarrhythmic drugs.
Conclusion-No difference in terms of success rate was seen between PVAI alone and PVAI associated with defragmentation. CFAEs ablation alone had the smallest impact on AF recurrences at 1-year follow-up. These results suggest that antral isolation is sufficient to treat most patients with paroxysmal AF.

AB Purpose: Although oncolytic viral vectors show promise for the treatment of various cancers, ineffective initial distribution and propagation throughout the tumor mass often limit the therapeutic response. A mathematical model is developed to describe the spread of herpes simplex virus from the initial injection site.
Experimental Design: The tumor is modeled as a sphere of radius R. The model incorporates reversible binding, interstitial diffusion, viral degradation, and internalization and physiologic parameters. Three species are considered as follows: free interstitial virus, virus bound to cell surfaces, and internalized virus.
Results: This analysis reveals that both rapid binding and internalization as well as hindered diffusion contain the virus to the initial injection volume, with negligible spread to the surrounding tissue. Unfortunately, increasing the dose to saturate receptors and promote diffusion throughout the tumor is not a viable option: the concentration necessary would likely compromise safety. However, targeted modifications to the virus that decrease the binding affinity have the potential to increase the number of infected cells by 1.5-fold or more, An increase in the effective diffusion coefficient can result in similar gains.
Conclusions: This analysis suggests criteria by which the potential response of a tumor to oncolytic herpes simplex virus therapy can be assessed. Furthermore, it reveals the potential of modifications to the vector delivery method, physicochemical properties of the virus, and tumor extracellular matrix composition to enhance efficacy.

AB Purpose: The dose-limiting toxicities, maximum tolerated dose, pharmacokinetic profile, and preliminary antitumor activity of neratinib (HKI-272), an irreversible pan ErbB inhibitor, were determined in patients with advanced solid tumors.
Experimental Design: Neratinib was administered orally as a single dose, followed by a 1-week observation period, and then once daily continuously. Planned dose escalation was 40, 80,120, 180, 240, 320, 400, and 500 mg. For pharmacokinetic analysis, timed blood samples were collected after administration of the single dose and after the first 14 days of continuous daily administration.
Results: Dose-limiting toxicity was grade 3 diarrhea, which occurred in one patient treated with 180 mg and in four patients treated with 400 mg neratinib; hence, the maximum tolerated dose was determined to be 320 mg. Other common neratinib-related toxicities included nausea, vomiting, fatigue, and anorexia. Exposure to neratinib was dose dependent, and the pharmacokinetic profile of neratinib supports a once-a-day dosing regimen. Partial response was observed for 8 (32%) of the 25 evaluable patients with breast cancer. Stable disease >= 24 weeks was observed in one evaluable breast cancer patient and 6 (43%) of the 14 evaluable non-small cell lung cancer patients.
Conclusion:The maximum tolerated dose of once-daily oral neratinib is 320 mg. The most common neratinib-related toxicity was diarrhea. Antitumor activity was observed in patients with breast cancer who had previous treatment with trastuzumab, anthracyclines, and taxanes, and tumors with a baseline ErbB-2 immunohistochemical staining intensity of 2+ or 3+. The antitumor activity, tolerable toxicity profile, and pharmacokinetic properties of neratinib warrant its further evaluation.

AB BACKGROUND: The ability to identify low-level somatic DNA mutations and minority alleles within an excess wild-type sample is becoming essential for characterizing early and posttreatment tumor status in cancer patients. Over the past 2 decades, much research has focused on improving the selectivity of PCR-based technologies for enhancing the detection of minority (mutant) alleles in clinical samples. Routine application in clinical and diagnostic settings requires that these techniques be accurate and cost-effective and require little effort to optimize, perform, and analyze.
CONTENT: Enrichment methods typically segregate by their ability to enrich for, and detect, either known or unknown mutations. Although there are several robust approaches for detecting known mutations within a high background of wild-type DNA, there are few techniques capable of enriching and detecting low-level unknown mutations. One promising development is COLD-PCR (coamplification at lower denaturation temperature), which enables enrichment of PCR amplicons containing unknown mutations at any position, such that they can be subsequently sequenced to identify the exact nucleotide change.
SUMMARY: This review summarizes technologies available for detecting minority DNA mutations, placing an emphasis on newer methods that facilitate the enrichment of unknown low-level DNA variants such that the mutation can subsequently be sequenced. The enrichment of minority alleles is imperative in clinical and diagnostic applications, especially in those related to cancer detection, and continued technology development is warranted.

AB BACKGROUND: Microarray-based genomic DNA profiling (MGDP) technologies are rapidly moving from translational research to clinical diagnostics and have revolutionized medical practices. Such technologies have shown great advantages in detecting genomic imbalances associated with genomic disorders and single-gene diseases.
CONTENT: We discuss the development and applications of the major array platforms that are being used in both academic and commercial laboratories. Although no standardized platform is expected to emerge soon, comprehensive oligonucleotide microarray platforms-both comparative genomic hybridization arrays and genotyping hybrid arrays-are rapidly becoming the methods of choice for their demonstrated analytical validity in detecting genomic imbalances, for their flexibility in incorporating customized designs and updates, and for the advantage of being easily manufactured. Copy number variants (CNVs), the form of genomic deletions/duplications detected through MGDP, are a common etiology for a variety of clinical phenotypes. The widespread distribution of CNVs poses great challenges in interpretation. A broad survey of CNVs in the healthy population, combined with the data accumulated from the patient population in clinical laboratories, will provide a better understanding of the nature of CNVs and enhance the power of identifying genetic risk factors for medical conditions.
SUMMARY: MGDP technologies for molecular diagnostics are still at an early stage but are rapidly evolving. We are in the process of extensive clinical validation and utility evaluation of different array designs and technical platforms. CNVs of currently unknown importance will be a rich source of novel discoveries. (C) 2009 American Association for Clinical Chemistry

AB BACKGROUND: DNA genotyping with mutation-specific TaqMan (R) probes (Applied Biosystems) is broadly used in detection of single-nucleotide polymorphisms but is less so for somatic mutations because of its limited selectivity for low-level mutations. We recently described coamplification at lower denaturation temperature-PCR (COLD-PCR), a method that amplifies minority alleles selectively from mixtures of wild-type and mutation-containing sequences during the PCR. We demonstrate that combining COLD-PCR with TaqMan technology provides TaqMan genotyping with the selectivity needed to detect low-level somatic mutations.
METHODS: Minor-groove binder-based or common TaqMan probes were designed to contain a nucleotide that matches the desired mutation approximately in the middle of the probe. The critical denaturation temperature (T(c)) of each amplicon was then experimentally determined. COLD-PCR/TaqMan genotyping was performed in 2 steps: denaturation at the T, followed by annealing and extension at a single temperature (fast COLD-PCR). The threshold cycle was used to identify mutations on the basis of serial dilutions of mutant DNA into wild-type DNA and to identify TP53 (tumor protein p53) and EGFR [epidermal growth factor receptor (erythroblastic leukemia viral (v-erb-b) oncogene homolog, avian)] mutations in tumors.
RESULTS: COLD-PCR/TaqMan genotyping identified G>A mutations within TP53 exon 8 (codon 273 mutation hot spot) and C>1 mutations within the EGFR gene (drug-resistance mutation T790M) with a selectivity improvement of 15- to 30-fold over regular PCR/TaqMan genotyping. A second round of COLD-PCR/TaqMan genotyping improved the selectivity by another 15- to 30-fold and enabled detection of I mutant in 2000 wild-type alleles. Use of COLD-PCR/TaqMan genotyping allowed quantitative identification of low-level TP53 and T790 mutations in colon tumor samples and in non-small-cell lung cancer cell lines treated with kinase inhibitors.
CONCLUSIONS: The major improvement in selectivity provided by COLD-PCR enables the popular TaqMan genotyping method to become a powerful tool for detecting low-level mutations in clinical samples. (C) 2008 American Association for Clinical Chemistry

AB Recent technological advances in photonics are making intravital microscopy (IVM) an increasingly powerful approach for the mechanistic exploration of biological processes in the physiological context of complex native tissue environments. Direct, dynamic and multiparametric visualization of immune cell behavior in living animals at cellular and subcellular resolution has already proved its utility in auditing basic immunological concepts established through conventional approaches and has also generated new hypotheses that can conversely be complemented and refined by traditional experimental methods. The insight that outgrowing tumors must not necessarily have evaded recognition by the adaptive immune system, but can escape rejection by actively inducing a state of immunological tolerance calls for a detailed investigation of the cellular and molecular mechanisms by which the anti-cancer response is subverted. Along with molecular imaging techniques that provide dynamic information at the population level, IVM can be expected to make a critical contribution to this effort by allowing the observation of immune cell behavior in vivo at single cell-resolution. We review here how IVM-based investigation can help to clarify the role of cytotoxic T lymphocytes (CTL) in the immune response against cancer and identify the ways by which their function might be impaired through tolerogenic mechanisms.

AB Background & Aims: Liver fibrosis is a significant concern for patients with hepatitis C virus/human immunodeficiency virus co-infection. Fibrosis staging by biopsy is accurate, but costly and invasive. Several fibrosis prediction models using noninvasive biomarkers have been developed but are suboptimal in co-infected patients. We compared results from different staging models and ordinal regression with biopsy data. Methods: Data from the Adult Acquired Immune Deficiency Syndrome Clinical Trials Group protocol A5178 were used to evaluate 5 models of fibrosis staging; areas under receiver-operator characteristic curves (AUROC) were assessed. Individual covariates were assessed with univariable regression and then entered into an ordinal logistic regression model from which a stage-wise index was developed. Results: Data from 173 patients were evaluated; 85% were on antiretroviral therapy, 31.2% had severe fibrosis (F3/F4), and 14% had cirrhosis (F4). Differences in CD4+ cell and platelets counts and international normalized ratio values were observed between those with and without F3/F4. Among existing models, the FIB-4 index ([age X AST])/[platelet count x (ALT)(1/2)]) performed best, with 88% specificity for F4 and greater than 86% negative predictive values for F3/F4, although AUROC values were low (0.56 +/- 0.03 for F3/F4). By using patients' demographic, clinical, and laboratory data, the ordinal regression model outperformed others, with an AUROC of 0.85 (standard error, 0.03) for predicting stage F3/F4 and 0.89 (standard error, 0.05) for stage 3 alone. Conclusion : Current noninvasive methods of fibrosis assessment have poor discriminatory capacity in hepatitis C virus/human immunodeficiency virus co-infected patients. Ordinal regression analysis outperformed other noninvasive fibrosis prediction models. Longitudinal studies with paired biopsies will assist in refining the Ordinal Regression Index.

AB Primary central nervous system lymphoma (PCNSL) is a rare, extranodal form of non-Hodgkin lymphoma that most commonly presents with neurologic changes. Comprehensive workup to diagnose PCNSL and rule out nodal non-Hodgkin lymphoma is critical to the development of an appropriate plan for therapy. Past PCNSL treatments have included whole-brain radiation or steroids, but high-dose methotrexate (MTX) has emerged as initial therapy. Although high-dose MTX is well tolerated, special considerations must be taken to administer the drug safely. Specific interventions include aggressive IV hydration with sodium bicarbonate fluids, monitoring blood chemistries, and the administration of leucovorin rescue. Nurses should evaluate and monitor patients closely during treatment to ensure safety and decrease drug toxicity.

AB Background and objectives: Novel individualized quality-of-life (IQOL) measures permit patients with chronic kidney disease (CKD) to nominate unique areas of their lives that contribute to their well-being. This study assessed for differences in domains nominated by patients with CKD. We also examined the strength of association between (1) multidimensional health-related quality-of-life measures and IQOL and (2) psychosocial factors and IQOL.
Design, setting, participants, & measurements: We performed a cross-sectional study of 151 patients who were undergoing peritoneal dialysis or hemodialysis or had stages 4 through 5 CKD. Patients completed the Schedule for the Evaluation of Individual Quality of Life-Direct Weighting (SEIQOL-DW), an instrument that assesses IQOL on the basis of patient-identified domains. Patients also completed health-related quality-of-life and psychosocial health measures.
Results: Patients with CKD nominated many domains on the SEIQOL-DW, but family and health were the most common for all groups. Kidney disease was listed more frequently by peritoneal dialysis compared with hemodialysis patients or patients with CKD (31 versus 14 versus 5%, respectively). There were no significant differences in SEIQOL-DW scores between subgroups. SEIQOL-DW scores correlated with mental well-being and inversely correlated with chronic stress and depression.
Conclusions: Patients with advanced CKD demonstrate compromised quality-of-life scores comparable to dialysis patients. IQOL measures provide unique information that may help guide interventions that are better tailored to address patients' concerns about their well-being. These findings also suggest that renal clinics should have staff available to address psychosocial aspects of patient well-being.

AB Background and objectives: Changes in ESRD reimbursement policy, including proposed bundled payment, have raised concern that dialysis facilities may use "cherry picking" practices to attract a healthier, better insured, or more adherent patient population.
Design, setting, participants, & measurements: As part of a national survey to measure beliefs about drivers of quality in dialysis, respondents were asked about their perceptions of cherry picking, including the frequency and effect of various cherry picking strategies on dialysis outcomes. We surveyed a random sample of 250 nurse members of the American Nephrology Nurses Association, 250 nephrologist members of the American Medical Association, 50 key opinion leaders, and 2000 physician members of the Renal Physicians Association. We tested hypothesized predictors of perception, including provider group, region, age, experience, and the main practice facility features.
Results: Three-quarters of respondents reported that cherry picking occurred "sometimes" or "frequently." There were no differences in perceptions by provider or facility characteristics, insurance status, or health status. In multivariable regression, perceived cherry picking was 2.8- and 3.5-fold higher in the northeast and Midwest, respectively, versus the west. Among various cherry picking strategies, having a "low threshold to 'fire' chronic no-shows/late arrivers," and having a "low threshold to 'fire' for noncompliance with diet and meds" had the largest perceived association with outcomes.
Conclusions: Under current reimbursement practices, dialysis caregivers perceive that cherry picking is common and important. An improved understanding of cherry picking practices, if evident, may help to protect vulnerable patients if reimbursement practices were to change.

AB Objectives: Epilepsy surgery is performed less frequently in persons over 45 years of age than in younger individuals, probably reflecting biases among patients, referring physicians and neurologists.
Methods: We report on a clinically heterogenous cohort of patients aged 45 years or older who underwent epilepsy surgery for medically intractable epilepsy.
Results: Over a 15-year period, 42 patients with a mean duration of epilepsy of 27.3 years underwent elective surgery. The mean follow-up period was 48 months. Thirty-two patients had an Engel class I outcome, of which 23 were totally seizure-free (Ia). Six patients had a class II outcome (rare disabling seizures), one had a class III outcome (worthwhile improvement), and three had a class IV outcome (no worthwhile improvement). The majority of patients reported an improved quality of life and satisfaction with the epilepsy surgery. A subjective improvement in cognition was reported in 7 patients while a decline was reported in 10 patients. New neuro psychiatric difficulties were reported in three patients while three patients reported improved anxiety after surgery. Only one patient became newly employed after surgery while 23 returned to driving. Permanent complications occurred in four patients (thalamic infarct during a Wada test (n = 1) and asymptomatic visual field defect (n = 3)).
Conclusions: We report a favorable outcome from epilepsy surgery in a large series of older adults and conclude that age per se is not a contraindication to epilepsy surgery. We emphasize the lack of correlation between outcome from surgery and pre-operative duration of epilepsy. (C) 2008 Elsevier B.V. All rights reserved.

AB Creutzfeldt-Jakob disease (CJD) is a rapidly progressive neurodegenerative disease caused by prions. Typically CJD presents with a triad of rapidly progressive dementia, abnormal movements (e.g., myoclonus) and electroencephalographic (EEG) changes. Recently, CJD has been subdivided into subtypes based on host genetic polymorphisms and the characteristics of the pathological prion protein. Different subtypes likely have different clinical and laboratory presentations. We describe a case of sporadic CJD of the VV1 subtype. We describe our patient's clinical symptoms, time course, laboratory workup, structural and functional neuroimaging data, EEG data and CJD biomarkers. Our patient presented with clinical symptoms atypical for CJD. Because of that, her clinical symptoms were initially attributed to psychiatric reasons. After extensive clinical and laboratory investigation, we concluded that the patient probably had CJD. Postmortem neuropathological results confirmed this clinical hypothesis. We compare our patient's clinical, laboratory and neuroimaging data to the data on typical CJD as well as the data on the few CJD VV1 cases described in the literature. We discuss our case's relevance to the diagnosis of CJD. (C) 2008 Elsevier B.V. All rights reserved.

AB Introduction: Effective management of major depressive disorder (MDD) continues to be a challenging task for psychiatrists and primary care physicians. This trial evaluated the efficacy and safety of adjunctive aripiprazole versus antidepressant monotherapy in patients with MDD and independently replicated the positive findings of two similar trials.,
Methods: Patients (N=1,147) with MDD experiencing a major depressive episode and a history of inadequate response to antidepressant monotherapy were enrolled (week 0); 827 received single-blind adjunctive placebo plus open-label antidepressant (escitalopram, fluoxetine, paroxetine controlled release, sertraline, or venlafaxine extended release) for 8 weeks to confirm inadequate response to antidepressants; 349 patients with inadequate response were randomized (1:1) to double-blind, adjunctive placebo (n=172) or adjunctive aripiprazole (n=177; 2-20 mg/day). Primary outcome was the mean change in Montgomery-angstrom sberg Depression Rating Scale (MADRS) Total score from baseline (week 8) to endpoint (week 14).
Results: Clinically significant improvements in depressive symptoms as assessed by decreases in the (MADRS) Total score were greater with adjunctive aripiprazole (-10.1) than placebo (-6.4; P<.001). Remission rates were greater for adjunctive aripiprazole than for adjunctive placebo (week 14, 36.8% vs 18.9%; P<.001). Completion rates with adjunctive aripiprazole and placebo were high (83% vs. 87%) and discontinuations due to adverse events were low (6.2% vs 1.7%).
Conclusion: For some patients with MDD who do not obtain adequate symptom relief with antidepressant monotherapy, adjunctive therapies can significantly improve. depressive symptoms. As reported, adjunctive aripiprazole was associated with a two-fold higher remission rate than adjunctive placebo. This, and previous studies, have shown that discontinuations due to adverse events were low and completion rates were high, and has indicated that both antidepressant and aripiprazole in combination, were relatively well-tolerated and safe. This is the third consecutive clinical trial, in the absence of a failed trial, to demonstrate that aripiprazole augmentation to antidepressants is an efficacious and well-tolerated treatment for patients with MDD who do not respond adequately to standard antidepressant monotherapy

AB Although it is well documented that individuals who have experienced traumatic events smoke cigarettes at significantly higher rates than individuals without exposure to trauma, the longitudinal relationship between smoking and trauma-related symptoms remains unclear. The present study examined this issue among 288 female veterans receiving treatment for trauma-related disorders over a period of up to 3 years. Consistent with previous cross-sectional research, across time points more symptomatology was associated with higher rates of smoking. Longitudinally, decreases in symptoms of negative affect over time were associated with decreases in smoking.

AB To determine if a delay in presentation to the emergency department (ED) after the onset of symptoms of an acute exacerbation of chronic obstructive pulmonary disease (AECOPD) increases the risk of hospital admission. A prospective cohort study utilizing data from 396 patient visits to 29 North American EDs. Inclusion criteria were age >= 55 years; a diagnosis of COPD; and presentation for treatment of AECOPD, as defined by increasing shortness of breath, worsening cough, or change in sputum production at presentation. The median age was 69 years and 54% were female. Most patients (70%) presented to the ED >24 hours after symptom onset, and most (61%) were hospitalized. On multivariate logistic regression analysis, after adjusting for 12 potential confounders (including demographics, clinical features, other diagnoses, and bronchodilator use before arrival), a delay in presentation >= 24 hours was associated with a over two-fold increase in the odds of admission (odds ratio = 2.2, 95% confidence interval 1.1-4.8). This increase in risk persisted for delay in presentation >= 12 hours in place of 24 hours, after restricting the analysis to patients admitted outside the intensive care unit, and to those reporting the ED as their usual site of care. A majority of patients delay presentation to the ED for >= 24 hours after symptom onset, and are at higher risk of hospitalization. Early presentation should be emphasized to patients and caregivers to advance efforts to decrease the morbidity, mortality, and costs of AECOPD treatment.

AB Objective: Anemia increases risk of bleeding complications in the critically ill. In primary intracerebral hemorrhage (ICH), the most fatal type of stroke, outcome is largely dependent on the volume of hemorrhage into the brain. We investigated the relationship between anemia and clinical course of acute ICH.
Methods. Six hundred ninety-four consecutive subjects were identified from an ongoing single-center prospective cohort study of nontraumatic ICH during a 6-year period. Anemia was defined according to World Health Organization criteria. Study end points were ICH volume, as measured on the baseline computed tomography scan, and 30-day mortality.
Results: Anemia was present in 177 (25.8%) patients on admission. Patients with anemia were older (p = 0.005) and more likely to have coronary artery disease (p < 0.0001). In multivariable analysis, anemia (p = 0.009), lobar location of ICH (p < 0.001), white blood cell count (p < 0.001), and admission diastolic blood pressure (p < 0.001) were associated with larger ICH volume. Although after accounting for ICH volume, none of these variables was a significant predictor of 30-day mortality in multivariable analysis, the size of the marginal reduction in the odds ratio for anemia suggests that it may have a small effect on mortality through mechanisms in addition to ICH volume.
Conclusions. Anemia is common in acute ICH and its presence at admission is an independent predictor of larger volume of ICH. Given the central role of ICH volume in outcome, clarification of the mechanisms underlying this relationship may offer novel therapeutic targets for reducing ICH morbidity and mortality.

AB Protein 4.1R (4.1R) is a multifunctional structural protein recently implicated in nuclear assembly and cell division. We earlier demonstrated that 4.1R forms a multiprotein complex with mitotic spindle and spindle pole organizing proteins, such as NuMA, dynein, and dynactin, by binding to residues 1788-1810 of NuMA through amino acids encoded by exons 20 and 21 in 24 kD domain. Employing randomand site-directed mutagenesis combined with glycine-and alanine-scanning, we have identified amino acids of 4.1R and NuMA that sustain their interaction, and have analyzed the effect of mutating the binding sites on their intracellular colocalization. We found that V762, V765, and V767 of 4.1R, and I1800, I1801, I1803, T1804, and M1805 of NuMA are necessary for their interaction. GST-fusion peptides of the 4.1R 24 kD domain bound to residues 1785-2115 of NuMA in in vitro binding assays, but the binding was inhibited by alanine substitutions of V762, V765, and V767 of 4.1R, or residues 1800-1805 of NuMA. Additionally, expression of variants of 4.1R or NuMA that inhibit their in vitro binding also abrogated nuclear localization of 4.1R and colocalization with NuMA. Our findings suggest a crucial role of 4.1R/NuMA interaction in localization and function of 4.1R in the nucleus.

AB Girls and women with type 1 diabetes have increased rates of disturbed eating behaviors and clinically significant eating disorders than their nondiabetic peers. Type 1 diabetes is strongly associated with several empirically supported eating disorder risk factors (eg, higher body mass index, increased body weight and shape dissatisfaction, low self-esteem and depression, and dietary restraint). It may be that specific aspects of diabetes treatment increase the risk for developing disordered eating. Disturbed eating behaviors and clinical eating disorders predispose women with diabetes to many complex medical risks and increase risk of morbidity and mortality. For this reason, it is critical that diabetes clinicians understand more about eating disorders to improve the likelihood of early risk detection and access to appropriate treatment. This article presents a review of the current scientific literature on eating disturbances in type 1 diabetes and synthesizes the existent findings into recommendations for screening and treatment.

AB The population is aging in the United States as well as worldwide. The prevalence of diabetes increases with increasing age. To provide optimal care to older adults with diabetes, unique psychosocial barriers need to be considered by medical providers. Unlike in younger adults, cognitive dysfunction/dementia and depressive mood disorders are common coexisting conditions in older adults with diabetes. This article reviews recent literature on epidemiology and clinical implications of cognitive and psychosocial dysfunctions in older patients with diabetes. This article focuses on cognitive dysfunctions, dementia, depression, and other psychosocial stresses, and their implications in the care of older adults with diabetes.

AB Objective: The 2007 American Thoracic Society/Infectious Diseases Society of America (ATS/IDSA) guidelines recommend that community-acquired pneumonia (CAP) patients admitted to hospital wards initially receive respiratory fluoroquinolone monotherapy or beta-lactam plus macrolide combination therapy. There is little evidence as to which regimen is preferred, or if differences in medical resource utilization exist between therapies. Thus, the authors compared length of hospital stay (LOS) and length of intravenous antibiotic therapy (LOIV) for patients who received initial levofloxacin 750 mg daily versus ceftriaxone 1000 mg plus azithromycin 500 mg daily ('combination therapy').
Research design and methods: Adult hospital CAP cases from January 2005 to December 2007 were identified by principal discharge diagnosis code. Patients with a chest infiltrate and medical notes indicative of CAP were included. Direct intensive care unit admits and healthcare-associated cases were excluded. A propensity score technique was used to balance characteristics associated with initial antimicrobial therapy using multivariable regression to derive the scores.
Propensity score categories, defined as propensity score quintiles, rather than propensity scores themselves, were used in the least squares regression model to assess the impact of LOS and LOIV.
Results: A total of 495 patients from six hospitals met study criteria. Of these, 313 (63%) received levofloxacin and 182 (37%) received combination therapy. Groups were similar with respect to age, sex, most comorbidities, presenting signs and symptoms, and Pneumonia Severity Index (PSI) risk class. Patients on combination therapy were more likely to have heart failure and receive pre-admission antibiotics. Adjusted least squares mean (+/- SE) LOS and LOIV were shorter with levofloxacin versus combination therapy: LOS, 4.6 +/- 0.17 vs. 5.4 +/- 0.22 days, p<0.01; and LOIV, 3.6 +/- 0.17 vs. 4.8 +/- 0.21 days, p<0.01. Results for PSI risk class III or IV patients were: LOS, 5.0 +/- 0.30 vs. 5.9 +/- 0.37 days, p=0.07; and LOIV, 3.7 +/- 0.33 vs. 5.2 +/- 0.39 days, p<0.01. Due to the retrospective study design, limited sample size, and scope (single health-network), the authors encourage replication of this study in other data sources.
Conclusions: Given the LOS and LOIV reductions of 0.8 and 1.2 days, respectively, utilization of levofloxacin 750 mg daily for CAP patients admitted to the medical floor has the potential to result in substantial cost savings for US hospitals.

AB Activation of the phosphoinositide-3-kinase (PI3K) signaling pathway is frequently found in common human cancers, brought about by oncogenic receptor tyrosine kinases (RTKs) acting upstream, PTEN loss, or activating mutations of PI3K itself. Recent studies have delineated distinct but overlapping functions in cell signaling and tumorigenesis for p110 alpha and p110 beta, the two major catalytic subunits of PI3K expressed in the tissues of origin for the common tumor types. In most cell types studied, p110 alpha carries the majority of the PI3K signal in classic RTK signal transcluction, while p110 beta responds to GPCRs. Both p11 alpha and p110 beta function in cellular transformation induced by alterations in components of PI3K pathway. Specifically, p110 alpha is essential for the signaling and growth of tumors driven by PIK3CA mutations and/or oncogenic RTKs/Ras, whereas p110 beta is the major isoform in mediating PTEN-deficient tumorigenesis. While pan-PI3K inhibitors are currently being tested in the clinic, p110 isoform-specific inhibition holds promise as a therapeutic strategy.

AB As an inhibitor of the tyrosine kinase activity of the BCR-Abl oncoprotein, imatinib sets a new paradigm for the treatment of cancer with molecularly targeted therapies. Subsequent structural studies have provided in depth knowledge of how this antileukaemia drug interacts with the catalytic site of the enzyme and allowed the rationalisation of mechanisms of drug-resistance which can lead to patient relapse. This understanding has facilitated the design of new inhibitors of BCR-Abl, as well as the discovery of inhibitors of many other kinases. As structural information accumulates for more of the 518 kinases encoded within the human genome, the design of many more highly selective, well-tolerated kinase inhibitors should be possible.

AB Purpose of review
To highlight recent type 2 diabetes (T2D)-associated genetic discoveries and their potential for clinical application.
Recent findings
The advent of genome-wide association screening has uncovered many loci newly associated with T2D. This review describes the techniques applied to discover novel T2D genes and compares their relative strengths, biases, and findings to date. The results of large-scale genome-wide association studies carried out since 2007 are summarized, and limitations of interpreting this preliminary data are offered. Recent studies exploring the clinical potential of these discoveries are reviewed, focusing on insights into T2D pathogenesis, risk prediction of future diabetes, and utility in guiding pharmacotherapy. The new T2D-associated loci have been implicated in beta-cell development and function, highlighting insulin secretion in the disease process. Preliminary risk prediction studies show that more loci are needed to improve T2D risk indices. Studies have also revealed that genes may play a role in the pharmacologic response to antidiabetic medications.
Summary
Since 2007, genome-wide association studies have rapidly increased the number of T2D-associated loci. This review summarizes the history of genetic association studies, the results from the new genome-wide association studies, and the clinical application of these findings.

Surgical intervention for patients with more recent diabetes onset may have higher rates of resolution than patients with longer duration disease. In addition, dyslipidemia and hypertension improve. A short-term randomized clinical trial comparing laproscopic banding with optimal medical management suggests surgery leads to more improvement in multiple metabolic measures. Perioperative risk is low and observational studies suggest long-term survival is favorable for obese patients following bariatric surgery. Metabolic risks of bariatric procedures are reviewed.
Summary
Although there are several surgical approaches for weight management, improvements in diabetes, including achievement of near normal glycemia without medication or reduced medications, are realized in many patients. Early surgical intervention for overweight type 2 diabetes may be clinically appropriate in patients for in whom operative risks are acceptable.

AB Purpose of review
During the last decade. laboratory tests for the detection of Mycobacterium tuberculosis (Mtb) have improved dramatically. Improvements in the ability to detect latent infection with Mtb. disease associated with Mtb, and strains resistant to commonly used antibiotics are reviewed.
Recent findings
Advances in the detection of Mtb include light-emitting diode fluorescence microscopy, nucleic acid amplification of Mtb and drug-resistant strains, and more rapid liquid culture with adjunct drug susceptibility testing. In the detection of latent tuberculosis infection, gamma release assays offer improved accuracy over the tuberculin skin test. interferon
Summary
The past 10 years have seen the most rapid growth in new diagnostics for Mtb in over a century. Although these tests offer improvements in the ability to detect Mtb, drug-resistant isolates. and those with latent tuberculosis infection, these improvements are counter-balanced by the need to deploy these tests in areas where Mtb burden is highest.

DE implications Istanbul Declaration; organ trafficking; transplant
tourism; transplant commercialism
AB Purpose of review
Organ trafficking, transplant tourism and transplant commercialism are now defined by the Declaration of Istanbul; the Declaration provides principles of practice based on those definitions. Organ trafficking and transplant tourism should be prohibited because they violate the principles of equity, justice and respect for human dignity.
Recent findings
This report provides a country-by-country description of current events that may effect the practice of transplantation internationally for the foreseeable future.
Summary
The implications of the Istanbul Declaration are profound. It calls for a legal and professional framework in each country to govern organ donation and transplantation activities. It calls for a transparent regulatory oversight system that ensures donor and recipient safety and enforces the prohibitions of unethical practices. Governments should ensure the provision of care and follow-up of living donors be no less than the care and attention provided for transplants recipients.

AB Purpose of review
The authors explore the literature published in the past year addressing child maltreatment issues, including sexual abuse, physical child abuse, inflicted head trauma, and child abuse prevention.
Recent findings
The body of knowledge about child abuse and its mimics continues to expand. Evident in this year's literature is the challenge which the diagnosis of child abuse creates for clinicians. Although further strides are being made toward universal education of providers, it is clear that there is still a reluctance to report abuse to child welfare agencies. The legal repercussions of diagnosing abuse can be extensive, and there has been a proliferation of medical defense experts who disagree with the commonly accepted tenets of abusive injury and who are vocal in the literature.
Summary
It remains the responsibility of pediatric providers to consider child maltreatment in the differential diagnosis of any unexplained injury or medical problem. Several studies document the high rate of spanking, slapping or shaking children, and primary care clinicians may be the first professionals in a position to begin the evaluation for possible child maltreatment. Despite the natural hesitancy to diagnose abuse, clinicians have an ethical and moral obligation to address this issue both in their practice and in their communities. The short-term and long-term costs to individuals who experience family violence have been well demonstrated and include not only emotional repercussions, but also chronic health conditions, which result in significant cost to society.

TI The Genetics of Reading Disability
SO CURRENT PSYCHIATRY REPORTS
LA English
DT Article
AB Genetic factors contribute substantially to the development of reading disability (RD). Family linkage studies have implicated many chromosomal regions containing RD susceptibility genes, of which putative loci at 1p34-p36 (DYX8), 2p (DYX3), 6p21.3 (DYX2), and 15q21 (DYX1) have been frequently replicated, whereas those at 3p12-q12 (DYX5), 6q13-q16 (DYX4), 11p15 (DYX7), 18p11 (DYX6), and Xq27 (DYX9) have less evidence. Association studies of positional candidate genes have implicated DCDC2 and KIAA0319 in DYX2, as well as C2ORF3 and MRPL19 (DYX3), whereas DYX1C1/EKN1 (DYX1) and ROBO1 (DYX5) were found to be disrupted by rare translocation breakpoints in reading-disabled individuals. Four of the candidate genes (DYX1C1, KIAA0319, DCDC2, and ROBO1) appear to function in neuronal migration and guidance, suggesting the importance of early neurodevelopmental processes in RD. Future studies to help us understand the function of these and other RD candidate genes promise to yield enormous insight into the neurobiologic mechanisms underlying the pathophysiology of this disorder.

AB Background: The phenomenon of compulsive boarding, characterized by the acquisition of and failure to discard a large number of possessions, is increasingly recognized as a significant public health burden. Despite the magnitude of the impairment associated with this condition, empirical research is still in the nascent stages and many facets of the phenomenology, underlying vulnerability and risk factors for boarding, are as of yet unknown. Method: The overall aim of the current investigation was to examine the association between boarding behaviors and two potential vulnerability factors-anxiety sensitivity (AS) and distress tolerance (DT). In addition, we investigated the robustness of these associations as well as the interaction between the two hypothesized risk factors. Three studies (total N = 745) involving independent nonclinical samples assessed hoarding, AS, DT, and relevant covariates using a range of measures. Results: Findings revealed that AS and boarding are significantly and robustly associated with one another beyond general depressive, anxiety, and nonhoarding obsessive-compulsive symptoms. Hoarding was also found to be associated with low DT Consistent with prediction, AS and DT interacted such that DT may play a less important role among individuals with low AS. By contrast, low DT appears to increase vulnerability to boarding symptoms among individuals high in AS. Results are discussed with regard to future research and treatment implications.

AB Background: The objective of this study was to compare personality traits between major depressive disorder (MDD) patients and healthy comparison subjects (HC) and examine if personality traits in patients are associated with specific clinical characteristics of the disorder. Methods: Sixty MDD patients (45 depressed, 15 remitted) were compared to 60 HC using the Temperament and Character Inventory. Analysis of covariance, with age and gender as covariates, was used to compare the mean Temperament and Character Inventory scores among the subject groups. Results: Depressed MDD patients scored significantly higher than HC on novelty seeking, harm avoidance, and self-transcendence and lower on reward dependence, self-directedness, and cooperativeness. Remitted MDD patients scored significantly lower than HC only on self-directedness. Comorbidity with anxiety disorder had a main effect only on harm avoidance. Harm avoidance was positively correlated with depression intensity and with number of episodes. Self-directedness bad an inverse correlation with depression intensity. Conclusions: MDD patients present a different personality profile from HC, and these differences are influenced by mood state and comorbid anxiety disorders. When considering patients who have been in remission for some time, the differences pertain to few personality dimensions. Cumulated number of depressive episodes may result in increased harm avoidance. Depression and Anxiety 26.382-388, 2009. (c) 2009 Wiky-Liss, Inc.

AB Adjuvant radiotherapy (ART) has been recommended for squamous cell carcinoma (SCC) with a high risk of recurrence, particularly perineurally invasive disease. The utility of ART is unknown. This study compares reported outcomes of high-risk SCC treated with surgical monotherapy (SM) with those of surgery plus ART (S+ART).
The Medline database was searched for reports of high-risk SCC treated with SM or S+ART that reported outcomes of interest: local recurrence, regional or distant metastasis, or disease-specific death.
There were no controlled trials. Of the 2,449 cases of high-risk SCC included, 91 were treated with S+ART. Tumor stage and surgical margin status before ART were generally unreported. In 74 cases of perineural invasion (PNI), outcomes were statistically similar between SM and S+ART. In 943 high-risk SCC cases in which clear surgical margins were explicitly documented, risks of local recurrence, regional metastasis, distant metastasis, and disease-specific death were 5%, 5%, 1%, and 1%, respectively.
High cure rates are achieved in high-risk cutaneous SCC when clear surgical margins are obtained. Current data are insufficient to identify high-risk features in which ART may be beneficial. In cases of PNI, the extent of nerve involvement appears to affect outcomes, with involvement of larger nerves imparting a worse prognosis.
The authors have indicated no significant interest with commercial supporters.

AB Whereas many molecules that promote cell and axonal growth cone migrations have been identified, few are known to inhibit these processes. In genetic screens designed to identify molecules that negatively regulate such migrations, we identified CRML-1, the C. elegans homolog of CARMIL. Although mammalian CARMIL acts to promote the migration of glioblastoma cells, we found that CRML-1 acts as a negative regulator of neuronal cell and axon growth cone migrations. Genetic evidence indicates that CRML-1 regulates these migrations by inhibiting the Rac GEF activity of UNC-73, a homolog of the Rac and Rho GEF Trio. The antagonistic effects of CRML-1 and UNC-73 can control the direction of growth cone migration by regulating the levels of the SAX-3 ( a Robo homolog) guidance receptor. Consistent with the hypothesis that CRML-1 negatively regulates UNC-73 activity, these two proteins form a complex in vivo. Based on these observations, we propose a role for CRML-1 as a novel regulator of cell and axon migrations that acts through inhibition of Rac signaling.

AB Trps1, the gene mutated in human Tricho-Rhino-Phalangeal syndrome, represents an atypical member of the GATA-family of transcription factors. Here we show that Trps1 interacts with Indian hedgehog (Ihh)/Gli3 signaling and regulates chondrocyte differentiation and proliferation. We demonstrate that Trps1 specifically binds to the transactivation domain of Gli3 in vitro and in vivo, whereas the repressor form of Gli3 does not interact with Trps1. A domain of 185aa within Trps1, containing three predicted zinc fingers, is sufficient for interaction with GIB. Using different mouse models we find that in distal chondrocytes Trps1 and the repressor activity of GIB are required to expand distal cells and locate the expression domain of Parathyroid hormone related peptide. In Columnar proliferating chondrocytes Trps1 and Ihh/Gli3 have an activating function. The differentiation of columnar and hypertrophic chondrocytes is Supported by TFPSI independent of Gli3. Trps1 seems thus to organize chondrocyte differentiation interacting with different subsets of co-factors in distinct cell types. (C) 2009 Elsevier Inc. All rights reserved.

RECEPTOR; OBESITY; MICE; RESISTANCE; ESTROGEN; GENDER
AB OBJECTIVE-To investigate how insulin sensitivity and glucose metabolism differ in adipocytes between different fat depots of male and female mice and how sex steroids contribute to these differences.
RESEARCH DESIGN AND METHODS-Adipocytes from intra-abdominal/perigonadal (PG) and subcutaneous (SC) adipose tissue from normal, castrated, or steroid-implanted animals were isolated and analyzed for differences in insulin sensitivity and glucose metabolism.
RESULTS-Adipocytes from both PG and SC depots of females have increased lipogenic rates compared with those from males. In females, intra-abdominal PG adipocytes are more insulin-sensitive than SC adipocytes and more insulin-sensitive than male adipocytes from either depot. When stimulated by low physiological concentrations of insulin, female PG adipocytes show a robust increase in Akt and extracellular signal-related kinase (ERK) phosphorylation and lipogenesis, whereas male adipocytes show activation only at higher insulin concentrations. Adipocytes from females have higher mRNA/protein levels of several genes involved in glucose and lipid metabolism. After castration, adipocytes of male mice showed increased insulin sensitivity and increased lipogenic rates, whereas adipocytes of females demonstrate decreased lipid production. Increasing estrogen above physiological levels, however, also reduced lipid synthesis in females, whereas increasing dihydrotestosterone in males had no effect.
CONCLUSIONS-There are major sex differences in insulin sensitivity in adipose tissue, particularly in the intra-abdominal depot, that, are regulated by physiological levels of sex steroids. The increased sensitivity to insulin and lipogenesis observed in adipocytes from females may account for their lower level of insulin resistance and diabetes risk despite similar or higher fat content than in males.

HYPERGLYCEMIA
AB OBJECTIVE-Type 2 diabetes results from a combination of insulin resistance and impaired insulin secretion. To directly address the effects of hepatic insulin resistance in adult animals, we developed an inducible liver-specific insulin receptor knockout mouse (iLIRKO).
RESEARCH DESIGN AND METHODS-Using this approach, we were able to induce variable insulin receptor (IR) deficiency in a tissue-specific manner (liver mosaicism).
RESULTS-iLIRKO mice presented progressive hepatic and extrahepatic insulin resistance without liver dysfunction. Initially, iLIRKO mice displayed hyperinsulinemia and increased beta-cell mass, the extent of which was proportional to the deletion of hepatic IR. Our studies of iLIRKO suggest a cause-and-effect relationship between progressive insulin resistance and the fold increase of plasma insulin levels and beta-cell mass. Ultimately, the beta-cells failed to secrete sufficient insulin, leading to uncontrolled diabetes. We observed that hepatic IGF-1 expression was enhanced in iLIRKO mice, resulting in an increase of circulating IGF-1. Concurrently, the IR-A isoform was upregulated in hyperplastic beta-cells of iLIRKO mice and IGF-1-induced proliferation was higher than in the controls. In mouse beta-cell lines, IR-A, but not IR-B, conferred a proliferative capacity in response to insulin or IGF-1, providing a potential explanation for the beta-cell hyperplasia induced by liver insulin resistance in iLIRKO mice.
CONCLUSIONS-Our studies of iLIRKO mice suggest a liver-pancreas endocrine axis in which IGF-1 functions as a liver-derived growth factor to promote compensatory pancreatic islet hyperplasia through IR-A. Diabetes 58:820-828, 2009

ID RAT VENTRICULAR MYOCYTES; RISK-FACTOR; WEIGHT; OBESITY; MICE;
HYPERTROPHY; INSULIN; MEN
AB OBJECTIVE - Obesity predisposes individuals to congestive heart failure (CHF) and cardiovascular disease (CVD). Leptin regulates energy homeostasis, is elevated in obesity, and influences ventricular and vascular remodeling. We tested the hypothesis that leptin levels are associated With greater risk of CHF, CVD, and mortality in elderly individuals.
RESEARCH DESIGN AND METHODS - We evaluated 818 elderly (mean age 79 years, 62% women) Framingham Study participants attending a routine examination at which plasma leptin was assayed.
RESULTS - Leptin levels were higher in women and strongly correlated with BMI (P < 0.0001). On follow-up (mean 8.0 years), 129 (of 775 free of CH F) participants developed CHF, 187 (of 532 free of CVD) experienced a first CVD event, and 391 individuals died. In multivariable Cox regression models adjusting for established risk factors, log-leptin was positively associated with incidence of CHF and CVD (hazard ratio [HR] per SD increment 1.26 [95% Cl 1.03-1.55] and 1.28 [1.09-1.50], respectively). Additional adjustment for BMI nullified the association with CHF (0.97 [0.75-1.24]) but only modestly attenuated the. relation to CVD incidence (1.23 [1.00-1.51], P = 0.052). We observed a nonlinear, U-shaped relation between log-leptin and mortality (P = 0.005 for quadratic term) with greater risk of death evident at both low and high leptin levels.
CONCLUSIONS - In our moderate-sized community-based elderly sample, higher circulating leptin levels were associated with a greater risk of CHF and CVD, but leptin did not provide incremental prognostic information beyond BMI. Additional investigations are warranted to elucidate the U-shaped relation of leptin to mortality.

ID SLEEP ONSET; NEUROPATHY; TEMPERATURE; TIME; DYSFUNCTION; DIAGNOSIS;
MELLITUS; FOOT; FEET
AB OBJECTIVE - To determine how thermoregulation of the feet is affected by diabetes and diabetic polyneuropathy in both wakefulness and sleep.
RESEARCH DESIGN AND METHODS - Normal subjects, diabetic subjects without neuropathy, diabetic subjects with small-fiber diabetic polyneuropathy, and those with advanced diabetic polyneuropathy were categorized based on neurological examination, nerve conduction studies; and quantitative sensory testing. Subjects underwent foot temperature monitoring using an iButton device attached to the foot and a second iButton for recording of ambient temperature. Socks and footwear were standardized, and subjects maintained an activity diary. Data were collected over a 32-h period and analyzed.
RESULTS - A total of 39 normal subjects, 28 patients with diabetes but without diabetic polyneuropathy, 14 patients with isolated small-fiber diabetic polyneuropathy, and 27 patients with more advanced diabetic polyneuropathy participated. No consistent differences in foot temperature regulation between the four groups were identified during wakefulness. During sleep, however, multiple metrics revealed significant abnormalities in the diabetic patients. These included reduced mean foot temperature (P < 0.001), reduced maximal temperature (P < 0.001), increased rate of cooling (P < 0.001), as well as increased frequency of variation (P = 0.005), supporting that patients with diabetic polyneuropathy and even those with out), diabetes but no diabetic polyneuropathy have impaired nocturnal thermoregulation.
CONCLUSIONS - Nocturnal foot thermoregulation is impaired in patients with diabetes and diabetic polyneuropathy. Because neurons are highly temperature sensitive and because foot warming is part of the normal biology of sleep onset and maintenance, these findings suggest new potentially treatable mechanisms of diabetes-associated nocturnal pain and sleep disturbance.

DT Article
ID INSULIN DELIVERY
AB Objectives: It has been proposed that the first step towards a closed-loop artificial pancreas might be to use a continuous glucose sensor to automatically suspend the basal insulin delivery based on projected low sensor glucose values.
Methods: We reviewed our recent experience with an artificial pancreas system, utilizing a proportional-integrative-derivative (PID) algorithm, in 17 adolescents with type 1 diabetes (T1D) to assess the safety and efficacy of this maneuver.
Results: During 34 h of closed-loop automated insulin delivery, 18 pump suspensions >= 60 min (90 +/- 18 min) occurred in eight subjects. Sensor glucose levels fell from 159 +/- 42mg/dL to a nadir of 72 +/- 13mg/dL. Corresponding plasma glucose levels fell from 168 +/- 51 to 72 +/- 16mg/dL, with values <60mg/dL recorded in only four of the 18 events.
Conclusions: These data suggest that automatic pump suspension using the PID algorithm may be an effective means to prevent hypoglycemia in youth with T1D.

TI TCF7L2 variants are associated with increased proinsulin/insulin ratios
but not obesity traits in the Framingham Heart Study

AB Common variants in the TCF7L2 gene are associated with type 2 diabetes via impaired insulin secretion. One hypothesis is that variation in TCF7L2 impairs insulin processing in the beta cell. In contrast, the association of related TCF7L2 polymorphisms with obesity is controversial in that it has only been shown in cohorts susceptible to ascertainment bias. We reproduced the association of diabetes-associated variants with proinsulin/insulin ratios, and also examined the association of a TCF7L2 haplotype with obesity in the Framingham Heart Study (FHS).
We genotyped the TCF7L2 single nucleotide polymorphisms rs7903146 and rs12255372 (previously associated with type 2 diabetes) and rs10885406 and rs7924080 (which tag haplotype A [HapA], a haplotype reported to be associated with obesity) in 2,512 FHS participants. We used age- and sex-adjusted linear mixed-effects models to test for association with glycaemic traits, proinsulin/insulin ratios and obesity measures.
As expected, the T risk allele of rs7903146 was associated with higher fasting plasma glucose (p = 0.01). T/T homozygotes had a 23.5% increase in the proinsulin/insulin ratio (p = 1 x 10(-7)) compared with C/C homozygotes. There was no association of HapA with BMI (p = 0.98), waist circumference (p = 0.89), subcutaneous adipose tissue (p = 0.32) or visceral adipose tissue (p = 0.92).
We confirmed that the risk allele of rs7903146 is associated with hyperglycaemia and a higher proinsulin/insulin ratio. We did not detect any association of the TCF7L2 HapA with adiposity measures, suggesting that this may have been a spurious association from ascertainment bias, possibly induced by the evaluation of obesity in separate groups of glycaemic cases and controls.

AB Islet amyloid in type 2 diabetes contributes to loss of beta cell mass and function. Since islets are susceptible to oxidative stress-induced toxicity, we sought to determine whether islet amyloid formation is associated with induction of oxidative stress.
Human islet amyloid polypeptide transgenic and non-transgenic mouse islets were cultured for 48 or 144 h with or without the antioxidant N-acetyl-l-cysteine (NAC) or the amyloid inhibitor Congo Red. Amyloid deposition, reactive oxygen species (ROS) production, beta cell apoptosis, and insulin secretion, content and mRNA were measured.
After 48 h, amyloid deposition was associated with increased ROS levels and increased beta cell apoptosis, but no change in insulin secretion, content or mRNA levels. Antioxidant treatment prevented the rise in ROS, but did not prevent amyloid formation or beta cell apoptosis. In contrast, inhibition of amyloid formation prevented the induction of oxidative stress and beta cell apoptosis. After 144 h, amyloid deposition was further increased and was associated with increased ROS levels, increased beta cell apoptosis and decreased insulin content. At this time-point, antioxidant treatment and inhibition of amyloid formation were effective in reducing ROS levels, amyloid formation and beta cell apoptosis. Inhibition of amyloid formation also increased insulin content.
Islet amyloid formation induces oxidative stress, which in the short term does not mediate beta cell apoptosis, but in the longer term may feed back to further exacerbate amyloid formation and contribute to beta cell apoptosis.

AB The regenerative process in the pancreas is of particular interest, since insulin-producing beta cells are lost in diabetes. Differentiation of new beta cells from pancreatic non-endocrine cells has been reported in vivo and in vitro, a finding that implies the existence of pancreatic stem/progenitor cells. However, while tissue-specific stem cells are well documented in skin, intestine and testis, pancreatic stem cells have been elusive. We hypothesised that pancreatic stem/progenitor cells within the non-endocrine fraction could be a source of new islets in vitro.
To test if there were such cells within the pancreas, we generated pancreatic cell aggregates from tissue remaining after islet isolation from mouse insulin promoter 1-green fluorescent protein (MIP-GFP) mice. To eliminate any contamination of insulin-positive cells, we deleted all GFP-positive aggregates using COPAS Select and cultured with Matrigel. Immunohistochemistry, quantitative real-time PCR and single-cell nested RT-PCR were performed to confirm formation of insulin-producing cells.
The GFP-negative cells were expanded as monolayers and then differentiated into three-dimensional cystic structures. After 1 week of culture, GFP-positive cells were found as clusters or single cells. By quantitative real-time PCR, no insulin mRNA was detected immediately after COPAS sorting, but after differentiation insulin mRNA of the whole preparation was 1.91 +/- 0.31% that of purified MIP-GFP beta cells. All GFP-positive cells expressed insulin 1; most expressed insulin 2, pancreas duodenum homeobox-1 and cytokeratin 19 by single cell nested RT-PCR.
Our data support the concept that within the exocrine (acinar and ductal) pancreas of the adult mouse there are cells that can give rise to insulin-positive cells in vitro.

AB The molecular mechanisms by which thiazolidinediones improve insulin sensitivity in type 2 diabetes are not fully understood. We hypothesised that pioglitazone would activate the adenosine 5'-monophosphate-activated protein kinase (AMPK) pathway and increase the expression of genes involved in adiponectin signalling, NEFA oxidation and mitochondrial function in human skeletal muscle.
A randomised, double-blind, parallel study was performed in 26 drug-naive type 2 diabetes patients treated with: (1) pioglitazone (n = 14) or (2) aggressive nutritional therapy (n = 12) to reduce HbA(1c) to levels observed in the pioglitazone-treated group. Participants were assigned randomly to treatment using a table of random numbers. Before and after 6 months, patients reported to the Clinical Research Center of the Texas Diabetes Institute for a vastus lateralis muscle biopsy followed by a 180 min euglycaemic-hyperinsulinaemic (80 mU m(-2) min(-1)) clamp.
All patients in the pioglitazone (n = 14) or nutritional therapy (n = 12) group were included in the analysis. Pioglitazone significantly increased plasma adiponectin concentration by 79% and reduced fasting plasma NEFA by 35% (both p < 0.01). Following pioglitazone, insulin-stimulated glucose disposal increased by 30% (p < 0.01), and muscle AMPK and acetyl-CoA carboxylase (ACC) phosphorylation increased by 38% and 53%, respectively (p < 0.05). Pioglitazone increased mRNA levels for adiponectin receptor 1 and 2 genes (ADIPOR1, ADIPOR2), peroxisome proliferator-activated receptor gamma, coactivator 1 gene (PPARGC1) and multiple genes involved in mitochondrial function and fat oxidation. Despite a similar reduction in HbA(1c) and similar improvement in insulin sensitivity with nutritional therapy, there were no significant changes in muscle AMPK and ACC phosphorylation, or the expression of ADIPOR1, ADIPOR2, PPARGC1 and genes involved in mitochondrial function and fat oxidation. No adverse (or unexpected) effects or side effects were reported from the study.
Pioglitazone increases plasma adiponectin levels, stimulates muscle AMPK signalling and increases the expression of genes involved in adiponectin signalling, mitochondrial function and fat oxidation. These changes may represent an important cellular mechanism by which thiazolidinediones improve skeletal muscle insulin sensitivity.

AB Background The management of patients with acute myocardial infarction (AMI) and upper gastrointestinal bleeding (UGIB) can present a challenge. The utility of upper endoscopy (esophagogastroduodenoscopy, EGD) and endoscopic therapy must be weighed against safety considerations. Aim To assess the utility and safety of EGD in patients with UGIB and AMI. Methods Using decision analysis, patients with UGIB and AMI were assigned to one of two strategies: (1) EGD prior to cardiac catheterization (EGD strategy) and (2) cardiac catheterization without EGD (CATH strategy). Results In patients with overt UGIB, the EGD strategy resulted in 97 deaths per 10,000 patients, compared with 600 deaths in the CATH strategy. The EGD strategy resulted in fewer non-fatal complications (1,271 vs. 6,000 per 10,000 patients). In patients with occult blood loss, the EGD strategy resulted in more deaths (59 vs. 16 per 10,000) and more non-fatal complications (888 vs. 160 per 10,000) than the CATH strategy. Conclusions Our analysis supports EGD prior to cardiac catheterization in patients with AMI and overt UGIB. This strategy results in fewer deaths and complications compared with a strategy of proceeding directly to catheterization. Our analysis does not support routine EGD prior to cardiac catheterization in patients with fecal occult blood.

AB Background: Difficulty walking is the most visible sign of disability among persons with multiple sclerosis (MS). However, little is known about mobility aid use by persons with MS living in the community.
Objectives: To explore perceptions of mobility problems related to MS and patterns of mobility aid use by persons with MS residing in communities across the United States.
Methods: We conducted a 30-minute telephone survey in mid-2007 with 703 community-dwelling, working-age adults who self-reported having MS. We identified potential survey respondents using membership lists of the National Multiple Sclerosis Society, over-sampling individuals living in zip codes with relatively high poverty rates. All analyses, including calculation of simple percentages, used sampling weights to produce population estimates. The overall response rate was 73.4%. Survey questions asked basic information about all mobility aids used by respondents and details about up to two different aids. We used multivariable polychotomous logistic regression to predict use of various mobility aids accounting for demographic and disease characteristics.
Results: In questions about the previous 2 weeks, needing to concentrate on walking because of MS was the most common problem cited (weighted percent = 79.3%), followed by MS making standing more difficult (69.9%), increased effort needed to walk (59.0%), and needing to hold onto furniture, walls, or someone's arm when walking indoors every day (40.0%). Among the 703 respondents, 434 (weighted percent = 60.5%) reported using at least one mobility aid; the majority of these individuals reported using more than one type of aid. Manual wheelchairs were the most common mobility aid (63.4%), followed by canes (56.7%), power wheelchairs (36.7%), and scooters (32.2%). Among those using three or more different types of mobility aids, the large majority used manual wheelchairs (88.2%), followed by canes (65.4%). Persons who are married or living with partners were much less likely to use powered equipment than those who were never married (adjusted odds ratio [AOR] = 0.32; 95% CI: 0.13-0.82). Women were much less likely than men to use powered equipment (AOR = 0.40; 95% CI: 0.21-0.75).
Conclusion: The vast majority of persons with MS who use at least one mobility aid own more than one type and about half own three or more different types of mobility aids. Persons with MS appear to "mix and match" different devices to suit their specific mobility needs. Given restrictive health insurance coverage policies for mobility aids, these findings raise questions about how persons acquire and pay for higher-technology mobility aids. (C) 2009 Elsevier Inc.

TI Perspectives on use of mobility aids in a diverse population of seniors:

DT Article
DE Mobility; Assistive technology; Hispanic; African American; Seniors
ID ASSISTIVE DEVICES; DISABILITY; CARE
AB Background: Many older adults who might benefit from using mobility aids do not or will not use them. Studies show that attitudes and beliefs strongly affect the decision to use mobility aids. Despite the growing diversity of the population, no prior studies have compared attitudes towards and beliefs about mobility aids by race and ethnicity.
Objective: This study aimed to explore whether and how attitudes towards and beliefs about mobility aid use vary by race and ethnicity.
Methods: We conducted 12 focus groups with 61 community dwelling persons age 65+ years from three groups: white, non-Hispanic black, and Hispanic. Data were coded and compared across groups.
Results: For all groups, perceived benefits of mobility devices in maintaining independence and control produced positive attitudes. However, the association of mobility aid use with aging and physical decline contributed to stigmatizing attitudes. Black and Hispanic participants expressed apprehension about using unsafe or inappropriate secondhand equipment, heightened concerns about mobility aid users becoming subjects of negative biases, and a preference for fashionable aids. Hispanic participants expressed a preference for human assistance. Participants of all groups perceived physicians as influencing their decisions to use aids.
Conclusion: Social pressures and perceived stigma deter mobility aid use, particularly in minority populations. Greater physician involvement, positive peer models, and affordable, safe, visually appealing devices would promote greater acceptance of mobility aids. (C) 2009 Elsevier Inc. All rights reserved.

AB PURPOSE: The objective of this study was to assess survival and prognostic factors for anal carcinoma in the population.
METHODS: Patients with squamous-cell carcinoma of the anal canal were identified from the National Cancer Data Base (1985-2000). Univariate and multivariable methods were used to assess factors associated with survival. Concordance was calculated to assess agreement between American Joint Committee on Cancer stage and actual outcome.
RESULTS: Nineteen thousand one hundred ninety-nine patients with anal carcinoma were identified (Stage I, 25.3 percent; Stage II, 51.8 percent; Stage III, 17.1 percent; Stage IV, 5.7 percent). Overall five-year survival was 58.0 percent. The American Joint Committee on Cancer (6th edition) staging system provided good survival discrimination by stage: I, 69.5 percent; II, 59.0 percent; III, 40.6 percent; and IV, 18.7 percent (concordance index, 0.663). On multivariable analysis, patients with anal carcinoma had a higher risk of death if they were male, >= 65 years old, black, living in lower median incomes areas, and had more advanced T stage tumors, nodal or distant metastases, or poorly differentiated cancers (P < 0.0001). There was not a significant difference in survival by hospital type or year of diagnosis.
CONCLUSION: Although tumor characteristics and staging affect prognosis, patient factors, such as gender, race, and socioeconomic status, are also important prognostic factors for squamous-cell carcinoma of the anal canal.

AB Studies demonstrating greater problem severity in substance abuse patients with posttraumatic stress disorder (PTSD) versus those without have rarely considered other co-occurring psychiatric disorders. This study of 466 male veterans recently admitted to outpatient substance abuse treatment attempts to identify problems associated with PTSD versus those associated with other nonsubstance use Axis I disorders. Problem severity, particularly psychiatric. was examined across four groups of patients with substance use disorders (SUDs). Those with: 1, SUDs only (SU-Only); 2, PTSD, but no other Axis I disorders (SU + PTSID): 3, PTSD and other Axis I disorders (SU + PTSD + Axis 1): and 4, no PTSD, but other Axis I disorders (SU + other Axis 1). Results suggested a hierarchy of psychiatric, and to a lesser extent, other life problem severities associated with these diagnostic groupings. The most severe group was SU + PTSD + Axis 1, followed in decreasing severity by the SU + other Axis 1, SU + PTSD, and SU-Only groups. Additional analyses comparing the SU + PTSD + Axis I patients with a subgroup of Axis I patients with more than one Axis I disorder (SU + multiple Axis 1) revealed few group differences except for more lifetime suicide attempts and psychiatric hospitalizations in the SU + PTSD + Axis I group. The findings suggest that it is not PTSD per se, but the frequent co-occurrence of PTSD and other psychopathology that largely accounts for previously reported greater problem severity of SLID patients with PTSD.

AB Diabetic retinopathy remains a major worldwide cause of preventable blindness. The isoform of protein kinase C (PKC) may play an important role in the pathogenesis of this disorder. Ruboxistaurin mesylate hydrate is an orally bioavailable, highly-specific inhibitor of PKC beta which has shown some efficacy in several large, multicenter, randomized clinical trials. The U.S. Food and Drug Administration issued an approvable letter for ruboxistaurin in 2006, but at this time the medication is not available for routine clinical use.

IMMUNIZATION
AB Alzheimer's disease is the most common form of dementia, primarily affecting individuals during or after their sixth decade of life. Despite decades of research, there are still no effective disease-modifying drugs available to treat this neurodegenerative disorder. Current FDA-approved medications primarily offer symptomatic relief and are based upon known neurotransmitter deficits. There are, however, many drugs in preclinical and clinical development which target other aspects of AD pathogenesis. Principal among these are drugs which modulate beta-amyloid, a protein that is believed to be central to the cascade which leads to the development of Alzheimer's disease. This article will outline the metabolism of P-amyloid and review a number of different strategies, including pitfalls and future directions of such methods that are directed towards the modulation of this protein. It will become clear that beta-amyloid represents a potent molecular target for pharmacological manipulation to perhaps prevent the onset and progression of Alzheimer's disease.

AB Background: The echocardiographic features of mitral valve prolapse (MVP) in Marfan syndrome have been well described, and the incidence of MVP in Marfan syndrome is reported to be 40-80%. However, most of the original research was performed in the late 1980s and early 1990s, when the diagnostic criteria for MVP were less specific. Our goal was to investigate the characteristics of MVP associated with Marfan syndrome using currently accepted diagnostic criteria for MVP. Methods: Between January 1990 and March 2004, 90 patients with definitive diagnosis of Marfan syndrome (based on standardized criteria with or without genetic testing) were referred to Massachusetts General Hospital for transthoracic echocardiography. Patients' gender, age, weight, height, and body surface area at initial examination were recorded. Mitral valve thickness and motion, the degree of mitral regurgitation and aortic regurgitation, and aortic dimensions were quantified blinded to patients' clinical information. Results: There were 25 patients (28%) with MVP, among whom 80% had symmetrical bileaflet MVP. Patients with MVP had thicker mitral leaflets (5.0 +/- 1.0 mm vs. 1.8 +/- 0.5 mm, P < 0.001), more mitral regurgitation (using a scale of 1-4, 2.2 +/- 1.0 vs. 0.90 +/- 0.60, P < 0.0001), larger LVEDD, and larger dimensions of sinus of Valsalva, sinotubular junction, aortic arch, and descending aorta indexed to square root body surface area, when compared with those without MVP. When echocardiographic features of patients younger than 18 years of age and those of patients older than 18 were compared, adult Marfan patients had larger LA dimension (indexed to square root body surface area), larger sinotubular junction (indexed to square root body surface area), and more mitral regurgitation and aortic regurgitation. Conclusions: The prevalence of MVP in Marfan syndrome is lower than previously reported. The large majority of patients with MVP have bileaflet involvement, and those with MVP have significantly larger aortic root diameters, suggesting a diffuse disease process.

EXPRESSION; MOUSE; TSH; CULTURE
AB To model the differentiation of thyroid epithelial cells, we examined embryoid bodies derived from undifferentiated murine embryonic stem cells treated with activin A to induce endoderm differentiation, the germ layer from which thyroid cells occur. The resulting endodermal cells were then further exposed to TSH and/or IGF-I for up to 21 d. Oct-4 and REX1 expression, required to sustain stem cell self-renewal and pluripotency, were appropriately down-regulated, whereas GATA-4, and alpha-fetoprotein, both endodermal-specific markers, increased as the embryonic stem cells were exposed to activin A. By d 5 culture, TSH receptor (TSHR) and sodium iodide symporter (NIS) gene and protein expression were markedly induced. Cells isolated by the fluorescence-activated cell sorter simultaneously expressed not only TSHR and NIS proteins but also PAX8 mRNA, an expression pattern unique to thyroid cells and expected in committed thyroid progenitor cells. Such expression continued until d 21 with no influence seen by the addition of TSH or IGF-I. The sequence of gene expression changes observed in these experiments demonstrated the emergence of definitive thyroid endoderm. The activin A induction of thyroid-specific markers, NIS and TSHR, occurred in the absence of TSH stimulation, and, therefore, the emergence of thyroid endoderm in vitro paralleled the emergence of thyroid cells in TSHR-knockout mice. Activin A is clearly a major regulator of thyroid endoderm. (Endocrinology 150: 1970-1975, 2009)

AB The thyroid hormone activating type 2 deiodinase (D2) is known to play a role in brown adipose tissue-mediated adaptive thermogenesis in rodents, but the finding of D2 in skeletal muscle raises the possibility of a broader metabolic role. In the current study, we examined the regulation of the D2 pathway in primary skeletal muscle myoblasts taken from both humans and mice. We found that pioglitazone treatment led to a 1.6- to 1.9-fold increase in primary human skeletal myocyte D2 activity; this effect was seen with other peroxisomal proliferator-activated receptor-gamma agonists. D2 activity in primary murine skeletal myotubes increased 2.8-fold in response to 5 mu M pioglitazone and 1.6- fold in response to 5 nM insulin and increased in a dose-dependent manner in response to lithocholic acid (maximum response at 25 mu M was similar to 3.8-fold). We compared Akt phosphorylation in primary myotubes derived from wild-type and D2 knockout (D2KO) mice: phospho-Akt was reduced by 50% in the D2KO muscle after 1 nM insulin exposure. Expression of T(3)-responsive muscle genes via quantitative RT-PCR suggests that D2KO cells have decreased thyroid hormone signaling, which could contribute to the abnormalities in insulin signaling. D2 activity in skeletal muscle fragments from both murine and human sources was low, on the order of about 0.01 fmol/min.mg of muscle protein. The phenotypic changes seen with D2KO cells support a metabolic role for D2 in muscle, hinting at a D2-mediated linkage between thyroid hormone and insulin signaling, but the low activity calls into question whether skeletal muscle D2 is a major source of plasma T(3).

AB OBJECTIVE: We previously demonstrated that exposure to polyvinyl chloride plastic medical devices containing di(2-ethylhexyl) phthalate (DEHP) was associated with higher urinary concentrations of several DEHP metabolites in 54 premature infants in two neonatal intensive care units than in the general population. For 42 of these infants, we evaluated urinary concentrations of several phenols, including bisphenol A (BPA), in association with the use of the same medical devices.
MEASUREMENTS: We measured the urinary concentrations of free and total (free plus conjugated) species of BPA, triclosan, benzophenone-3, methyl paraben, and propyl paraben.
RESULTS: The percentage of BPA present as its conjugated species was > 90% in more than three-quarters of the premature infants. Intensity of rise of products containing DEHP was strongly associated with BPA total concentrations but not with any other phenol. Adjusting for institution and sex, BPA total concentrations among infants in the group of high use of DEHP-containing products were 8.75 times as high as among infants in the low use group (p < 0.0001). Similarly, after adjusting for sex and DEHP-containing product use category, BPA total concentrations among infants in Institution A were 16.6 times as high as those among infants in Institution B (p < 0.0001).
CONCLUSION: BPA geometric mean urinary concentration (30.3 mu g/L) among premature infants undergoing intensive therapeutic medical interventions was one order of magnitude higher than that among the general population. Conjugated species were the primary urinary metabolites of BPA, suggesting that premature infants have some capacity to metabolize BPA. The differences in exposure to BPA by intensity of use of DEHP-containing medical products highlight the need for further studies to determine the specific source(s) of exposure to BPA.

AB We previously showed that Candida albicans orf19.4590, which we have renamed RFX2, expresses a protein that is reactive with antibodies in persons with candidiasis. In this study, we demonstrate that C. albicans RFX2 shares some functional redundancy with Saccharomyces cerevisiae RFX1. Complementation of an S. cerevisiae rfx1 mutant with C. albicans RFX2 partially restored UV susceptibility and the repression of DNA damage response genes. DNA damage- and UV-induced genes RAD6 and DDR48 were derepressed in a C. albicans rfx2 null mutant strain under basal conditions, and the mutant was significantly more resistant to UV irradiation, heat shock, and ethanol than wild-type strain SC5314. The rfx2 mutant was hyperfilamentous on solid media and constitutively expressed hypha-specific genes HWP1, ALS3, HYR1, ECE1, and CEK1. The mutant also demonstrated increased invasion of solid agar and significantly increased adherence to human buccal epithelial cells. During hematogenously disseminated candidiasis, mice infected with the mutant had a significantly delayed time to death compared to the wild type. During oropharyngeal candidiasis, mice infected with the mutant had significantly lower tissue burdens in the oral cavity and esophagus at 7 days and they were less likely to develop disseminated infections because of mucosal translocation. data demonstrate that C. albicans Rfx2p regulates DNA damage responses, morphogenesis, and virulence.

AB Solid-support based assays offer several advantages that are not normally available in solution. Enzymes that are anchored on gold surfaces can interact with several different molecules, opening the way to high throughput array format based assays. In this scenario, surface plasmon resonance (SPR) and mass spectrometry (MS) investigations have often been applied to analyze the interaction between immobilized enzyme and its substrate molecules in a tag-free environment. Here, we propose a SPR-MS combined experimental approach aimed at studying insulin degrading enzyme (IDE) immobilized onto gold surfaces and its ability to interact with insulin. The latter is delivered by a microfluidic system to the IDE functionalized surface and the activity of the immobilized enzyme is verified by atmospheric pressure/matrix assisted laser desorption ionization (AP/MALDI) MS analysis. The SPR experiments allow the calculation of the kinetic constants involved for the interaction between immobilized IDE and insulin molecules and evidence of IDE conformational change upon insulin binding is also obtained.

AB A recent genome-wide association study identified a haplotype block on chromosome 4q25 associated with atrial fibrillation (AF). We sought to replicate this association in four independent cohorts.
The Framingham Heart Study and Rotterdam Study are community-based longitudinal studies. The Vanderbilt AF Registry and German AF Network (AFNet) are case-control studies. Participants with AF (n = 3508) were more likely to be male and were older than referent participants (n = 12 173; Framingham 82 +/- 10 vs. 71 +/- 13 years; Rotterdam 73 +/- 8 vs. 69 +/- 9 years; Vanderbilt 54 +/- 14 vs. 57 +/- 14 years; AFNet 62 +/- 12 vs. 49 +/- 14 years). Single nucleotide polymorphism (SNP) rs2200733 was associated with AF in all four cohorts, with odds ratios (ORs) ranging from 1.37 in Rotterdam [95% confidence interval (CI) 1.18-1.59; P = 3.1 x 10(-5)] to 2.52 in AFNet (95% CI 2.22-2.8; P = 1.8 x 10(-49)). There also was a significant association between AF and rs10033464 in Framingham (OR 1.34; 95% CI 1.03-1.75; P = 0.031) and AFNet (OR 1.30; 95% CI 1.13-1.51; P = 0.0002), but not Vanderbilt (OR 1.16; 95% CI 0.86-1.56; P = 0.33). A meta-analysis of the current and prior AF studies revealed an OR of 1.90 (95% CI 1.60-2.26; P = 3.3 x 10(-13)) for rs2200733 and of 1.36 (95% CI 1.26-1.47; P = 6.7 x 10(-15)) for rs10033464.
The non-coding SNPs rs2200733 and rs10033464 are strongly associated with AF in four cohorts of European descent. These results confirm the significant relations between AF and intergenic variants on chromosome 4.

AB To determine the effects of omega-3 polyunsaturated fatty acids (omega-3 PUFAs) from fish on the incidence of recurrent ventricular arrhythmia in implantable cardioverter defibrillator (ICD) patients by combining results from published trials.
We searched in the Medline, EMBASE, and Cochrane databases and performed a meta-analysis on all three available trials on fish oil and ventricular arrhythmia. Furthermore, we pooled individual data of two of these randomized, double-blind, placebo-controlled trials (Raitt et al. Fish oil supplementation and risk of ventricular tachycardia and ventricular fibrillation in patients with implantable defibrillators: a randomized controlled trial. JAMA 2005;293:2884-2891 and Brouwer et al. Effect of fish oil on ventricular tachyarrhythmia and death in patients with implantable cardioverter defibrillators: the Study on Omega-3 Fatty Acids and Ventricular Arrhythmia (SOFA) randomized trial. JAMA 2006;295:2613-2619). The main outcome was time to first confirmed ventricular fibrillation (VF) or ventricular tachycardia (VT) combined with death for the meta-analysis, and time to first spontaneous confirmed VF or VT for the pooled analysis. The meta-analysis (n = 1148) showed no convincing protective effect of fish oil (RR 0.90; 95% CI 0.67-1.22). The hazard ratio for the subgroup of patients with coronary artery disease at baseline (0.79; 0.60-1.06) tended towards a protective effect. The pooled analysis (n = 722) showed that time to appropriate ICD intervention was similar for fish oil and placebo treatment (log-rank P = 0.79).
These findings do not support a protective effect of omega-3 PUFAs from fish oil on cardiac arrhythmia in all patients with an ICD. Current data neither prove nor disprove a beneficial or a detrimental effect for subgroups of patients with specific underlying pathologies.

AB The aim of this study was to assess whether pericardial fat, intrathoracic fat, and visceral abdominal adipose tissue (VAT) are associated with the prevalence of cardiovascular disease (CVD).
Participants from the Framingham Heart Study Offspring cohort underwent abdominal and chest multidetector computed tomography to quantify volumes of pericardial fat, intrathoracic fat, and VAT. Relations between each fat depot and CVD were assessed using logistic regression. The analysis of 1267 participants (mean age 60 years, 53.8% women, 9.7% with prevalent CVD) demonstrated that pericardial fat [odds ratio (OR) 1.32, 95% confidence interval (CI) 1.11-1.57; P = 0.002] and VAT (OR 1.35, 95% CI 1.11-1.57; P = 0.003), but not intrathoracic fat (OR 1.14, 95% CI 0.93-1.39; P = 0.22), were significantly associated with prevalent CVD in age-sex-adjusted models and after adjustment for body mass index and waist circumference. After multivariable adjustment, associations were attenuated (P > 0.14). Only pericardial fat was associated with prevalent myocardial infarction after adjusting for conventional measures of adiposity (OR 1.37, 95% CI 1.03-1.82; P = 0.03).
Pericardial fat and VAT, but not intrathoracic fat, are associated with CVD independent of traditional measures of obesity but not after further adjustment for traditional risk factor. Taken together with our prior work, these findings may support the hypothesis that pericardial fat contributes to coronary atherosclerosis.

AB We aimed to determine the relationship between body mass index (BMI) and cardiovascular events among individuals with or at-risk of atherothrombotic disease.
This was a prospective observational study of 15 532 patients enrolled in the Clopidogrel for High Atherothrombotic Risk and Ischemic Stabilization, Management, and Avoidance (CHARISMA) trial who were randomly assigned to clopidogrel or placebo, and followed-up for a median of 28 months for the occurrence of the primary endpoint (cardiovascular death, myocardial infarction, or stroke), all-cause mortality, and bleeding complications. Compared with the highest BMI quartile, the primary endpoint, cardiovascular, and all-cause mortality all occurred more frequently among patients in the lowest BMI quartile (about a third lower). The relationship between continuous BMI and adverse cardiovascular outcomes were presented as two linear spline terms with 29 kg/m(2) as the cut-point for all-cause mortality. Lower BMI was associated with an increase in moderate and severe bleeding complications, largely accounted for by those receiving dual-antiplatelet agents with the highest tertile aspirin dose.
Adverse cardiovascular events and bleeding complications occurred more frequently among individuals with or at-risk for atherothrombotic disease and low BMI. Further studies should be directed to these patients to improve outcomes.
The CHARISMA trial is registered with ClinicalTrials.gov, NCT00050817.

AB Making sense of rapidly evolving evidence on genetic associations is crucial to making genuine advances in human genomics and the eventual integration of this information in the practice of medicine and public health. Assessment of the strengths and weaknesses of this evidence, and hence the ability to synthesize it, has been limited by inadequate reporting of results. The STrengthening the REporting of Genetic Association studies (STREGA) initiative builds on the STrengthening the Reporting of OBservational Studies in Epidemiology (STROBE) Statement and provides additions to 12 of the 22 items on the STROBE checklist. The additions concern population stratification, genotyping errors, modelling haplotype variation, Hardy-Weinberg equilibrium, replication, selection of participants, rationale for choice of genes and variants, treatment effects in studying quantitative traits, statistical methods, relatedness, reporting of descriptive and outcome data and the volume of data issues that are important to consider in genetic association studies. The STREGA recommendations do not prescribe or dictate how a genetic association study should be designed, but seek to enhance the transparency of its reporting, regardless of choices made during design, conduct or analysis.

AB It is important to find a reliable and bedside method, which can estimate the cerebral blood flow (CBF) of patients in clinical settings. Estimation of CBF by calculating a blood flow index (BFI) using continuous wave near-infrared spectroscopy (CW-NIRS) and indocyanine green (ICG) as an iv tracer has been proposed to be a feasible and promising method. To validate if the BFI method can detect relative changes in CBF we compared data with the established method (133)Xenon single photon emission computer tomography ((133)Xe-SPECT).
Ten healthy subjects were investigated before and after a bolus of acetazolamide. NIRS data were obtained using a multi source detector separation configuration in order to assess a corrected BFI (BFI(corr)) value, which attempts to eliminate contamination of skin blood flow.
Data obtained showed no significant correlation between CBF changes measured by (133)Xe-SPECT and BFI(corr) (0.133, P = 0.732). After acetazolamide, a 49% increase in CBF was detected using the (133)Xe-SPECT method, whereas no changes in any ICG variables were observed after acetazolamide.
The study shows that it is not possible to obtain reliable BFI data, which reflect changes in CBF after acetazolamide infusion, using the CW-NIRS and ICG method.

AB Transforming growth factor-beta 1 (TGF-beta 1) regulates a variety of cellular responses that are dependent on the developmental stage and on the origins of the cell or the tissue. In mature tissues, and especially in tissues of epithelial origin, TGF-beta 1 is generally considered to be a growth inhibitor that may also promote apoptosis. The ameloblast cells of the enamel organ epithelium are adjacent to and responsible for the developing enamel layer on unerupted teeth. Once the enamel layer reaches its full thickness, the tall columnar secretory-stage ameloblasts shorten, and a portion of these maturation-stage ameloblasts become apoptotic. Here we investigate whether TGF-beta 1 plays a role in apoptosis of the maturation-stage ameloblasts. We demonstrate in vitro that ameloblast lineage cells are highly susceptible to TGF-beta 1-mediated growth arrest and are prone to TGF-beta 1-mediated cell death/apoptosis. We also demonstrate in vivo that TGF-beta 1 is expressed in the maturation-stage enamel organ at significantly higher levels than in the earlier secretory-stage enamel organ. This increased expression of TGF-beta 1 correlates with an increase in expression of the enamel organ immediate-early stress-response gene and with a decrease in the anti-apoptotic Bcl2 : Bax expression ratio. We conclude that TGF-beta 1 may play an important role in ameloblast apoptosis during the maturation stage of enamel development.

ID ATLANTO-OCCIPITAL DISLOCATION
AB Powers ratio, as assessed on plain radiographs or computed tomography (CT) images, appears to have clinical and prognostic value. To date, the validation of this assessment tool has been limited to a small number of observers at a single site. No study has examined the intraobserver reproducibility and interobserver reliability of the Powers ratio measurement on plain radiographs or CT images among a large cohort of spine surgeons. This type of validation is critical to allow for the broader use of the Powers ratio methodology in research studies and clinical applications. Plain radiographs and spiral CT images of the cervical spine of 32 patients were assessed, and the Powers ratio was determined by five spine surgeons. Each surgeon performed three readings, 7 months apart. In the first round of measurements, the observers used only the Powers' method of instruction. The second and third measurement sets were obtained after an interactive teaching session on the methodology. The order of the images was altered for the second and third set of measurements. The coefficient of variation (Cv) was calculated to determine the intraobserver repeatability and interobserver reliability for each imaging technique. A Bland-Altman plot was then used to assess the agreement between the two imaging techniques. For interobserver reliability, the mean Cv of the Powers ratio was 9.09 and 4.31% for plain radiographs and CT, respectively. The Cv mean value for intraobserver reproducibility averaged 4.95% (range 1.39-9.08) when CT scans were used and 14.17% (range 7.54-34.30) when plain radiographs were used. For intraobserver reproducibility, the lowest and highest Cv mean value of five raters was 1.39 and 9.08% using CT scans and 7.54 and 34.3% using plain radiographs. The Bland-Altman plot, demonstrated that the two methods were in close agreement on the -0.8 and 0.89% interval for limits of agreement (bias +/- A 1.96 sigma). The intraobserver reproducibility and interobserver reliability of Powers ratio measurement was acceptable (< 5%) with CT scans but not with plain radiographs. However, despite the statistically inferior reliability and repeatability, the Bland-Altman plot analysis showed that given the -0.8 and 0.89% limits of agreement, the two methods may be used interchangeably in clinical practice.

DT Article

ID RENAL-FAILURE; NECROSIS
AB Calciphylaxis is a poorly understood syndrome of vascular calcification and skin necrosis. It affects 1-4% of the population with end stage renal disease (ESRD). Disorders implicated in the pathogenesis of calciphylaxis include chronic renal failure, hypercalcemia, hyperphosphatemia, an elevated calcium-phosphate product, and secondary hyperparathyroidism (Essary, L.R. and Wick, M.R. (2000) Cutaneous calciphylaxis. An underrecognized clinicopathologic entity. Am. J. Clin. Pathol. 113, 280-287, Beitz, J.M. (2004) Calciphylaxis: an uncommon but potentially deadly form of skin necrosis. Am. J. Nurs. 104, 36-37.). Although these abnormalities are extremely common in-patients with ESRD, calciphylaxis is relatively rare. The mortality rate of calciphylaxis is about 60-80%. The leading cause of death is sepsis from necrotic skin lesions (Hitti, W. A., Papadimitriou, J.C., Bartlett, S. and Wali, R.K. (2007) Spontaneous cutaneous ulcers in a patient with a moderate degree of chronic kidney disease: a different spectrum of calciphylaxis. Scand. J. Urol. Nephrol. 1-3.). Here, we report a case of calciphylaxis in a 23-year-old female with past history of chronic renal failure, renal transplantation and intake of immunosuppressive drug. The relevant literature was discussed. (C) 2009 Elsevier Inc. All rights reserved.

AB The trabecular meshwork is one of the primary tissues of interest in the normal regulation and dysregulation of intraocular pressure (IOP) that is a causative risk factor for primary open-angle glaucoma. Matricellular proteins generally function to allow cells to modulate their attachments with and alter the characteristics of their surrounding extracellular matrix (ECM). In non-ocular tissues, matricellular proteins generally increase fibrosis. Since ECM turnover is very important to the outflow facility, matricellular proteins may have a significant role in the regulation of IOP. The formalized study of matricellular proteins in trabecular meshwork is in its infancy. SPARC, thrombospondins-1 and -2, and tenascins-C and -X, and osteopontin have been localized to varying areas within the trabecular meshwork. Preliminary evidence indicates that SPARC and thrombospondin-1 play a role in the regulation of IOP and possibly the pathophysiology of glaucoma. These data show promise that matricellular proteins are involved in IOP dysregulation and are potential therapeutic targets. Further study is needed to clarify these roles. (C) 2008 Elsevier Ltd.

AB Glaucoma is the major cause of irreversible blindness worldwide. Primary open-angle glaucoma (POAG), as the most prevalent form of glaucoma, is a complex inherited disorder and affects more than 2 million individuals in the United States. It has become increasingly clear that a host of genetic as well as environmental factors are likely to contribute to the phenotype. A number of chromosomal and genetic associations have been reported for POAG. This review examines what is currently known about the underlying genetic structure, what remains to be learned, and how this may affect our medical management of this major blinding disease.

AB A substantial body of evidence has accumulated over the past 35 years in support of a role for oxidative damage to the mitochondrial respiratory chain and mitochondrial DNA in the determination of mammalian lifespan. The goal of this review is to provide a concise summary of recent studies using transgenic and knockout mouse models with altered expression of mitochondrial antioxidant enzymes (MnSOD (Sod2Tg and Sod2(+/-)), thioredoxin 2 (Trx2(+/-)), mitochondrial targeted catalase (mCAT) and mutant mice models that have been genetically manipulated to increase mitochondrial deletions or mutations (Poly(D257A/D257A) mutant mice) to examine the role of mitochondrial oxidative stress in aging. The majority of studies using these strategies do not support a clear role for mitochondrial oxidative stress or a vicious cycle of oxidative damage in the determination of lifespan in mice and furthermore do not support the free radical theory of aging. However, several key questions remain to be addressed and clearly more studies are required to fully understand the role of mitochondria in age-related disease and aging. (C) 2009 Elsevier Inc.

AB The presence of high frequency discharge neurons with long periods of silence or "pauses" in the globus pallidus pars externa (GPe) is a unique identifying feature of this nucleus. Prior studies have demonstrated that pause characteristics reflect synaptic inputs into GPe. We hypothesized that GPe pause characteristics should distinguish movement disorders whose basal ganglia network abnormalities are different. We examined Pause characteristics in 224 GPe units in patients with primary generalized dystonia, Parkinson's disease (PD), and secondary dystonia, undergoing single unit microelectrode recording for DBS placement in the awake state. Pauses in neuronal discharge Were identified using the Poisson surprise method. Mean pause length in primary dystonia (606.8373.3) was higher than in PD (557.4366.6) (p < 0.05). Interpause interval (IPI) was lower in primary dystonia (2331.63874.1) than PD (3646.45894.5) (p < 0.01), and mean pause frequency was higher in primary dystonia (0.140.10) than PD (0.070.12) (p < 0.01). Comparison of pause characteristics in primary versus secondary generalized dystonia revealed a significantly longer mean pause length in primary (606.8373.3) than in secondary dystonia (495.6236.5) (p < 0.01). IPI was shorter in primary (2331.6 +/- 3874.1) than in secondary dystonia (3484.5 +/- 3981.6) (p < 0.01). The results show that pause characteristics recorded in the awake human GPe distinguish primary dystonia from Parkinson's disease and secondary dystonia. The differences may reflect increased phasic input from striatal D2 receptor positive cells in primary dystonia, and are consistent with a recent model proposing that GPe provides capacity scaling for cortical input.

AB Background: Chronic periodontitis is a widely prevalent inflammatory condition of the supporting tissues of the teeth and is characterized by loss of teeth with an associated risk of systemic complications. Regenerative therapies such as guided tissue and bone regeneration form an important armamentarium in periodontics with a high degree of outcome predictability in certain ideal clinical scenarios. Objective/methods: This review elaborates novel tissue regenerative treatment modalities based on sound understanding of developmental biology, tissue engineering, inflammation and wound healing. We focus on the role of biological mediators such as growth factors, gene-based therapy, cell therapy and pro-resolution lipid mediators in the regeneration of lost bone or periodontium. Results/conclusions: These therapies have the potential to regenerate both periodontium and bone, aiding in the treatment of even clinically challenging cases.

AB Despite advances in therapy, Waldenstrom's macroglobulinemia (WM) remains incurable. Guidelines on therapeutic alternatives in WM recommended the use of alkylating agents, rituximab, nucleoside analogues and anthracyclins either in first line or at relapse and in combination in fit patients. While the overall response rates of combination regimens reached up to 80 - 90% in some studies, the complete response rate is low, no greater than 10 - 20%; and the disease-related median survival for symptomatic patients is approximately 6 years. As such, new therapeutic agents are needed for the treatment of WM. In ongoing efforts, advances were made in the understanding of the biology of WM so as to better target therapeutics for this malignancy. Several preclinical studies have demonstrated that the NF kappa B pathway is a potential target for therapeutics in WM. Bortezomib (Velcade (R)) is the first approved proteasome inhibitor for treating relapse/refractory multiple myeloma and, among other mechanisms of action, significantly inhibits the NFkB pathway. This report provides an update on biological studies and clinical efforts to develop bortezomib as a new treatment of Waldenstrom's macroglobulinemia.

AB Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide and one of the few malignancies with an increasing incidence in the USA. While the relationship between HCC and its inciting risk factors (e.g., hepatitis B, hepatitis C and alcohol liver disease) is well defined, driving genetic alterations are still yet to be identified. Clinically, HCC tends to be hypervascular and, for that reason, transarterial chemoembolization has proven to be effective in managing many patients with localized disease. More recently, angiogenesis has been targeted effectively with pharmacologic strategies, including monoclonal antibodies against VEGF and the VEGF receptor, as well as small-molecule kinase inhibitors of the VEGF receptor. Targeting angiogenesis with these approaches has been validated in several different solid tumors since the initial approval of bevacizumab for advanced colon cancer in 2004. In HCC, only sorafenib has been shown to extend survival in patients with advanced HCC and has opened the door for other anti-angiogenic strategies. Here, we will review the data supporting the targeting of the VEGF axis in HCC and the preclinical and early clinical development of bevacizumab.

AB Glioblastomas are the most common and lethal form of malignant primary brain tumors. Although some progress has been made, the impact of recent advances in multimodality therapies on clinical outcome has been disappointing, with a median survival of less than 15 months. A major challenge in patients with glioblastomas is the propensity of the tumor to invade into adjacent brain tissue. Invasive tumor cells escape surgical removal and, because of their reduced proliferation rate and increased resistance to apoptosis, they are relatively resistant to radiation therapy and chemotherapy. Recently, there has been important progress in understanding the molecular determinants of glioma invasion and migration. This review will summarize some of the therapeutic strategies for inhibiting invasion in glioblastomas.

AB Among 2,245 women, those who experienced a chemical pregnancy that failed to progress to a clinically recognized pregnancy or a spontaneous abortion on their first IVF cycle were more likely to discontinue IVF treatment than those whose first cycle ended before embryo transfer or who did not have a positive pregnancy test after transfer. However, among women who did continue to a second IVF cycle, those who had at least a chemical pregnancy on the first cycle were more likely to have a live birth on the second attempt than those women who had failed before conception in the first cycle (34% success rate compared with 21%, respectively).

AB Background & Aims: The peroxisome proliferator-activated receptor gamma (PPARG, PPARgamma) is a nuclear receptor that regulates expression of mediators of lipid metabolism and the inflammatory response. There is controversy over the pro-oncogenic or antioncogenic effects of PPARG, and little is known about its prognostic significance in colon cancer. Methods: Among 470 patients with colorectal. cancer (stages I-M identified in 2 independent prospective cohorts, PPARG expression was detected in 102 tumors (22%) by immunohistochemistry. Cox proportional hazards models were used to compute hazard ratios (HRs) of colorectal cancer-specific and overall mortalities, adjusted for patient characteristics and molecular features including cyclo-oxygenase 2, fatty acid synthase, KRAS, BRAF, PIK3CA, p53, p21,beta-catenin, LINE-1 hypomethylation, microsatellite instability (MSI), and the CpG island methylation phenotype (CIMP). Results: Compared with patients with PPARG-negative tumors, patients with PPARG-positive tumors had significantly lower overall. mortality, determined by Kaplan-Meier analysis (P = .0047), univariate Cox regression (HR, 0.55; 95% confidence interval [CI], 0.37-0.84; P = .0053), and multivariate analysis (adjusted HR, 0.43; 95% CI, 0.27-0.69; P = .0004). Patients with PPARG-positive tumors experienced lower colorectal cancer-specific mortality (adjusted HR, 0.44; 95% CI, 0.25-0.79; P = .0054). The relationship between PPARG and lower mortality did not appear to be significantly modified by MSI, CIMP, LINE-1, or the other clinical and molecular variables examined (all P(interaction) > .05). Conclusions: Tumor expression of PPARG is independently associated with longer survival of patients. PPARG expression appears to mark an indolent subset of colorectal cancers.

AB Background & Aims: Chronic psychological stress is associated with visceral hyperalgesia. and increased expression of spinal NK1 receptors (NK1Rs). We aimed to identify the role of spinal microglia in this process. Methods: Male Wistar rats were exposed to water avoidance (WA) or sham stress 1 hour each day for 10 days and given daily injections of minocycline, the p38 inhibitor SB203580, or saline. Phosphorylation levels of the kinase p38 (P-p38), the microglia marker OX42, NK1R, and I kappa B alpha were assessed by immunoblotting and/or immunostaining of spinal samples collected at day 11. The visceromotor response to colorectal. distention at baseline and following WA were also assayed in rats given injections of minocycline, SB203580, or vehicle. The effects of fractalkine were assessed on the visceromotor response in rats exposed to minocycline or vehicle. Results: P-p38 protein levels and immunoreactivity were increased in stressed rats and colocalized with OX42-positive cells and neurons in the dorsal horn. This increase was reversed by minocycline or SB203580 exposure. Stress-induced increased NK1R expression was blocked by minocycline but not SB203580. WA-induced decreased I kappa B alpha expression was blocked by minocycline and SB203580. WA-induced hyperalgesia was blocked by minocycline and SB203580 intrathecally. Fractalkine-induced hyperalgesia was blocked by minocycline. Conclusions: This is the first demonstration that stress-induced activation of spinal microglia has a key role in visceral hyperalgesia and associated spinal NKIR up-regulation.

AB Gene delivery to stem cells holds great potential for tissue regeneration and delivery of therapeutic proteins. The major barrier is the lack of safe and efficient delivery methods. Here, we report enhanced gene delivery systems for human stem cells using biodegradable polymeric vectors. A library of poly (beta- amino esters) end-modified derivatives was developed and optimized for high transfection efficiency and low cytotoxicity for three human stem cell lines including human mesenchymal stem cells (hMSCs), human adipose-derived stem cells (hADSCs) and human embryonic stem cell-derived cells (hESCds). In the presence of 10% serum, leading end-modified C32 polymeric vectors exhibited significantly high transfection efficiency in hMSCs (27 +/- 2%), hADSCs (24 +/- 3%) and hESCds (56 +/- 11%), with high cell viability (87 - 97%) achieved in all cell types. Our results show that poly(beta-amino esters) as a class, and end-modified versions of C32 in particular, are efficient polymeric vectors for gene delivery to both adult and embryonic-derived stem cells.

AB Vibrio cholerae causes a dehydrating diarrheal illness that can be rapidly fatal in the absence of specific treatment. The organism is an historic scourge and, like similar infectious diseases, may have influenced the evolution of the human genome. We report here the results of the first candidate gene association study of cholera. In a family-based study of 76 pedigrees from Dhaka, Bangladesh, we evaluated the association between cholera and five candidate genes-the cystic fibrosis transmembrane receptor; lactoferrin; long palate, lung and nasal epithelium clone 1 (LPLUNC1); estrogen-related receptor alpha and calcium-activated chloride channel 1. We found a significant association with a marker in the promoter region of LPLUNC1 (rs11906665), a member of a family of evolutionarily conserved innate immunity proteins. An earlier microarray-based study of duodenal biopsies showed significantly increased expression of LPLUNC1 in cholera patients compared with healthy control subjects. Our results suggest that variation in host innate immune responses may influence the outcome of exposure to V. cholerae in an endemic setting.

AB Emerging molecular and clinical data suggest that ETS fusion prostate cancer represents a distinct molecular subclass, driven most commonly by a hormonally regulated promoter and characterized by an aggressive natural history. The study of the genomic landscape of prostate cancer in the light of ETS fusion events is required to understand the foundation of this molecularly and clinically distinct subtype. We performed genome-wide profiling of 49 primary prostate cancers and identified 20 recurrent chromosomal copy number aberrations, mainly occurring as genomic losses. Co-occurring events included losses at 19q13.32 and 1p22.1. We discovered three genomic events associated with ERG rearranged prostate cancer, affecting 6q, 7q, and 16q. 6q loss in nonrearranged prostate cancer is accompanied by gene expression deregulation in an independent dataset and by protein deregulation of MYO6. To analyze copy number alterations within the ETS genes, we performed a comprehensive analysis of all 27 ETS genes and of the 3 Mbp genomic area between ERG and TMPRSS2 (21q) with an unprecedented resolution (30 bp). We demonstrate that high-resolution tiling arrays can be used to pinpoint breakpoints leading to fusion events. This study provides further support to define a distinct molecular subtype of prostate cancer based on the presence of ETS gene rearrangements. (C) 2009 Wiley-Liss, lnc.

AB The last several years have seen an explosion of information relating to the transcriptional control of brown fat cell development. At the same time, new data have emerged that clearly demonstrate that adult humans do indeed have substantial amounts of functioning brown adipose tissue ( BAT). Together, these advances are stimulating a reassessment of the role of brown adipose tissue in human physiology and pathophysiology. These data have also opened up exciting new opportunities for the development of entirely novel classes of therapeutics for metabolic diseases like obesity and type 2 diabetes.

AB The small GTP-binding protein, Rho1/RhoA plays a central role in cytokinetic actomyosin ring (CAR) assembly and cytokinesis. Concentration of Rho proteins at the division site is a general feature of cytokinesis, yet the mechanisms for recruiting Rho to the division site for cytokinesis remain poorly understood. We find that budding yeast utilizes two mechanisms to concentrate Rho1 at the division site. During anaphase, the primary mechanism for recruiting Rho1 is binding to its guanine nucleotide exchange factors (GEFs). GEF-dependent recruitment requires that Rho1 has the ability to pass through its GDP or unliganded state prior to being GTP-loaded. We were able to test this model by generating viable yeast lacking all identifiable Rho1 GEFs. Later, during septation and abscission, a second GEF-independent mechanism contributes to Rho1 bud neck targeting. This GEF-independent mechanism requires the Rho1 polybasic sequence that binds to acidic phospholipids, including phosphatidylinositol 4,5-bisphosphate (PIP2). This latter mechanism is functionally important because Rho1 activation or increased cellular levels of PIP2 promote cytokinesis in the absence of a contractile ring. These findings comprehensively define the targeting mechanisms of Rho1 essential for cytokinesis in yeast, and are likely to be relevant to cytokinesis in other organisms.

AB We performed a genome-wide siRNA screen in mouse embryonic stem (ES) cells to identify genes essential for self-renewal, and found 148 genes whose down-regulation caused differentiation. Many of the identified genes function in gene regulation and/or development, and are highly expressed in ES cells and embryonic tissues. We further identified target genes of two transcription regulators Cnot3 and Trim28. We discovered that Cnot3 and Trim28 co-occupy many putative gene promoters with c-Myc and Zfx, but not other pluripotency-associated transcription factors. They form a unique module in the self-renewal transcription network, separate from the core module formed by Nanog, Oct4, and Sox2. The transcriptional targets of this module are enriched for genes involved in cell cycle, cell death, and cancer. This supports the idea that regulatory networks controlling self-renewal in stem cells may also be active in certain cancers and may represent novel anti-cancer targets. Our screen has implicated over 100 new genes in ES cell self-renewal, and illustrates the power of RNAi and forward genetics for the systematic study of self-renewal.

AB Purpose: This qualitative study explored black and white general internists' attitudes about the relevance of race in clinical care; views of the relationships among race, genetics, and disease; and expectations about the future of genetics and health. Methods: We conducted 10 racially concordant focus groups of primary care physicians in five metropolitan areas in the United States. Ninety board certified or eligible general internists (50 self-identified whites and 40 self-identified blacks) participated in the study, Analysis included a two-stage independent review and adjudication process. Results: Both black and white physicians concluded that the race of the patient is medically relevant but did not agree upon why race is important in clinical decisions. They were reticent to make connections among race, genetics, and disease and asserted that genetics has a limited role in explaining racial differences in health. However, they were enthusiastic about the future of genomic medicine, believing that the main benefit will be the potential to improve the efficacy of commonly used drugs. Conclusions: Understanding the similarities and differences between black and white physicians' attitudes and beliefs about race, health and genetics is important for the translation of genomics to clinical care.

AB Severe ocular trauma causing no light perception (NLP) typically carries a dismal prognosis, and implies no further therapeutic intervention. We have identified a cohort of patients with verified NLP following open-globe injury who have recovered vision of light perception (LP) or better. We evaluated the outcomes of vitreoretinal surgery performed on eyes that were NLP post open-globe injury.
Retrospective review of outcomes of secondary vitreoretinal surgery performed at Massachusetts Eye and Ear Infirmary from 1 January 2001 to 31 December 2006 on all cases of open-globe repair (OGR) that had NLP prior to OGR or on the first post-operative day.
A total of 648 cases of OGR were performed in the study period. Eighty-eight patients had NLP prior to OGR or on the first post-operative day after OGR. Twenty-three patients from the above group (26.1%) spontaneously recovered a vision of light perception (LP) or better. Eight of the 23 patients had a secondary vitreoretinal surgery. All eyes that did not undergo vitreoretinal surgery returned to NLP or became phthisical within 7 months. Among the eight eyes that underwent surgery, five had improvement, with vision ranging from hand motion to 20/70. Prognostic indicators for successful surgical outcome were hand motion or better vision prior to vitreoretinal surgery, recovery of vision within 5 days of OGR, and vitreoretinal intervention within 5 weeks of the initial open-globe injury.
Patients with severe open-globe injury and NLP occasionally recover LP or better vision. These patients may regain useful vision after vitreoretinal surgery if prompt referral and intervention is attempted and if the spontaneous visual recovery occurs within the first week after OGR.

ID UNINTENDED CONSEQUENCES; PERFORMANCE; IMPROVEMENT; MDS
AB The impact of quality improvement incentives on nontargeted care is unknown and some have expressed concern that such incentives may be harmful to nontargeted areas of care. Our objective is to examine the effect of publicly reporting quality information on unreported quality of care.
The nursing home Minimum Data Set from 1999 to 2005 on all postacute care admissions.
We studied 13,683 skilled nursing facilities and examined how unreported aspects of clinical care changed in response to changes in reported care after public reporting was initiated by the Centers for Medicare and Medicaid Services on their website, Nursing Home Compare, in 2002.
We find that overall both unreported and reported care improved following the launch of public reporting. Improvements in unreported care were particularly large among facilities with high scores or that significantly improved on reported measures, whereas low-scoring facilities experienced no change or worsening of their unreported quality of care.
Public reporting in the setting of postacute care had mixed effects on areas without public reporting, improving in high-ranking facilities, but worsening in low-ranking facilities. While the benefits of public reporting may extend beyond areas that are being directly measured, these initiatives may also widen the gap between high- and low-quality facilities.

ID CLUSTER-ANALYSIS; PERFORMANCE; COST
AB To develop and explore the characteristics of a novel "nearest neighbor" methodology for creating peer groups for health care facilities.
Data were obtained from the Department of Veterans Affairs (VA) databases.
Peer groups are developed by first calculating the multidimensional Euclidean distance between each of 133 VA medical centers based on 16 facility characteristics. Each medical center then serves as the center for its own peer group, and the nearest neighbor facilities in terms of Euclidean distance comprise the peer facilities. We explore the attributes and characteristics of the nearest neighbor peer groupings. In addition, we construct standard cluster analysis-derived peer groups and compare the characteristics of groupings from the two methodologies.
The novel peer group methodology presented here results in groups where each medical center is at the center of its own peer group. Possible advantages over other peer group methodologies are that facilities are never on the "edge" of a group and group size-and thus group dispersion-is determined by the researcher. Peer groups with these characteristics may be more appealing to some researchers and administrators than standard cluster analysis and may thus strengthen organizational buy-in for financial and quality comparisons.

AB Low success rates with triple therapy for Helicobacter pylori infections have prompted search for alternatives. In one, a proton-pump inhibitor (PPI) and amoxicillin was followed by the PPI plus clarithromycin and a nitroimidazole (sequential therapy); in another, these four drugs were given concomitantly (concomitant therapy).
To compare concomitant therapy with standard triple therapy for H. pylori infection.
By searching PubMed, EMBASE, the Cochrane Central Register of Controlled Trials and abstracts of major gastrointestinal meeting, two independent reviewers systemically identified randomized controlled trials (RCT) comparing concomitant quadruple to standard triple therapies as well as studies reporting eradication rates of concomitant quadruple therapy in treatment of H. pylori. Pooled eradication rates and odds ratios (OR) with 95% confidence intervals (CI) were calculated, and univariable metaregression analysis for all extracted variables was conducted.
We identified nine studies (10 treatment arms) including five qualifying RCTs (576 subjects) comparing concomitant (293 subjects, duration 3 to 5 days) and triple therapy (283 subjects, duration 5 to 10 days) and four other studies evaluating concomitant therapy (478 subjects, duration 3 to 7 days). Pooled estimates of the five RCTs showed superiority of concomitant therapy over triple therapy; with intention-to-treat) pooled OR of 2.86 (95% CI: 1.73-4.73) and per-protocol (PP) pooled OR of 3.52 (95% CI: 1.95-6.38). Considering all 10 treatment arms, the ITT eradication rate was 89.7% (95% CI: 86.8-92.1%) and PP was 92.9% (95% CI: 90.2-94.8%).
Concomitant therapy appears to be an effective alternative to triple therapy and is less complex than sequential therapy.

AB In comparison to past decades, children who have acquired aplastic anemia (AA) enjoy excellent overall survival that reflects improvements in supportive care, more accurate exclusion of children who have alternate diagnoses, and advances in transplantation and immunosuppressive therapy (IST). Matched sibling-donor hematopoietic stem cell transplants (HSCT) routinely provide long-term survival in the range of 90%, and 75% of patients respond to IST. In this latter group, the barriers to overall and complication-free survival include recurrence of AA, clonal evolution with transformation to myelodysplasia/acute myelogenous leukemia, and therapy-related toxicities. Improvements in predicting responses to IST, in alternative-donor HSCT, and in rationalizing therapy by understanding the pathophysiology in individual patients are likely to improve short- and long-term outcomes for these children.

AB Despite 100,000 ventral hernia repairs (VHR) being performed annually, no gold standard for the technique exists. Mesh has been shown to decrease recurrence rates, yet, concerns of increased complications and costs prevent its systematic use. We examined the cost-effectiveness of open suture (OS) versus open mesh (OM) in primary VHR.
A decision analysis model from the payer's perspective comparing OS to OM was constructed for calculating the total costs and cost-effectiveness. Probabilities for complications and outcomes were derived from the literature. The costs represented institutional fixed costs. The outcome measure of effectiveness was recurrence. One-way sensitivity analysis and a probabilistic analysis using Monte Carlo simulation were performed.
OS was associated with a total cost of $16,355 (+/- 6,041) per repair, while OM was $16,947 (+/- 7,252). At 3-year follow-up, OM was the more effective treatment with 73.8% being recurrence-free, compared with 56.3% in the OS group. The incremental cost to prevent one recurrence by the placement of mesh was $1,878. OM became the less effective treatment strategy when the infection rate exceeded 35%. At a willingness to pay level of $5,500, OM was the more cost-effective treatment strategy.
In subjects without contraindication to mesh placement, OM repair is the more effective surgical treatment for VHR, with a lower risk of recurrence at a small cost to the payer.

AB Although magnetoencephalography (MEG) and electroencephalograph), (EEG) have been available for decades, their relative merits are still debated. We examined regional differences in signal-to-noise-ratios (SNRs) of cortical sources in MEG and EEG. Data from four subjects were used to simulate focal and extended Sources located on the cortical surface reconstructed from high-resolution magnetic resonance images. The SNR maps for MEG and EEG were found to be complementary. The SNR of deep sources was larger in EEG than in MEG, whereas the opposite was typically the case for Superficial Sources. Overall, the SNR maps were more uniform for EEG than for MEG. When using a noise model based on Uniformly distributed random sources on the cortex, the SNR in MEG was found to be underestimated, compared with the maps obtained with noise estimated from actual recorded MEG and EEG data. With extended Sources, the total area of cortex in which the SNR was higher in EEG than in MEG was larger than with focal sources. Clinically, SNR maps in a patient explained differential sensitivity of MEG and EEG in detecting epileptic activity. Out results emphasize the benefits of recording MEG and EEG simultaneously.

AB Previously, we introduced the use of individual cortical location and orientation constraints in the spatiotemporal Bayesian dipole analysis setting proposed by Jun et al. ([2005], Neuroimage 28:84-98). However, the model's performance was limited by slow convergence and multimodality of the numerically estimated posterior distribution. In this paper, we present an intuitive way to exploit functional magnetic resonance imaging (fMRI) data in the Markov chain Monte Carlo sampling -based inverse estimation of magnetoencephalographic (MEG) data. We used Simulated MEG and fMRI data to show that the convergence and localization accuracy of the method is significantly improved with the help of fMRI-guided proposal distributions. We further demonstrate, using an identical visual stimulation paradigm in both fMRI and MEG, the usefulness of this type of automated approach when investigating activation patterns with several spatially close and temporally overlapping Sources. Theoretically, the MEG inverse estimates are not biased and should yield the same results even without fMRI information, however, in practice the multimodality of the posterior distribution causes problems due to the limited mixing properties of the sampler. On this account, the algorithm acts perhaps more as a stochastic optimizer than enables a full Bayesian posterior analysis. Hum Brain Mapp 30:1087-1099, 2009. (C) 2008 Wiley-Liss, Inc.

AB Human and animal studies suggest that acupuncture produces many beneficial effects through the central nervous system. However, the neural substrates of acupuncture actions are not completely clear to date. FMRI studies at Hegu (L14) and Zusanli (ST36) indicated that the limbic system may play an important role for acupuncture effects. To test if this finding applies to other major classical acupoints, fMRI was performed on 10 healthy adults during manual acupuncture at Taichong (LV3), Xingjian (LV2), Neiting (ST44), and a sham point on the dorsum of the left foot. Although certain differences could be observed between real and sham points, the hemodynamic response (BOLD signal changes) and psychophysical response (sensory experience) to acupuncture were generally similar for all four points. Acupuncture produced extensive deactivation of the limbic-paralimbic-neocortical System. Clusters of deactivated regions were seen in the medial prefrontal cortex (frontal pole, pregenual cingulate), the temporal lobe (amygdala, hippocampus, and parahippocampus) and the posterior medial cortex (precuneus, posterior cingulate). The sensorimotor cortices (somatosensory cortices, supplementary motor cortex), thalamus and occasional paralimbic structures Such as the insula and anterior middle cingulate cortex showed activation. Our results provide additional evidence in support of previous reports that acupuncture modulates the limbic-paralimbic-neocortical network. We hypothesize that acupuncture may mediate its antipain, antianxiety, and other therapeutic effects via this intrinsic neural circuit that plays a central role in the affective and cognitive dimensions of pain as well as in the regulation and integration of emotion, memory processing, autonomic, endocrine, immunological, and sensorimotor functions.

AB Hereditary neuralgic amyotrophy (HNA) is an autosomal dominant disorder associated with recurrent episodes of focal neuropathy primarily affecting the brachial plexus. Point mutations in the SEPT9 gene have been previously identified as the molecular basis of HNA in some pedigrees. However in many families, including those from North America demonstrating a genetic founder haplotype, no sequence mutations have been detected. We report an intragenic 38 Kb SEPT9 duplication that is linked to HNA in 12 North American families that share the common founder haplotype. Analysis of the breakpoints showed that the duplication is identical in all pedigrees, and molecular analysis revealed that the duplication includes the 645 bp exon in which previous HNA mutations were found. The SEPT9 transcript variants that span this duplication contain two in-frame repeats of this exon, and immunoblotting demonstrates larger molecular weight SEPT9 protein isoforms. This exon also encodes for a majority of the SEPT9 N-terminal proline rich region suggesting that this region plays a role in the pathogenesis of HNA.

AB Background Randomized controlled trials (RCTs) of duloxetine (DLX), an inhibitor of both norepinephrine and serotonin transporters (SNRI), have tested its efficacy in acute major depressive disorder (MDD) versus placebo (PBO) or standard serotonin-reuptake inhibitors (SRIs) and require review, comparing analytical methods.
Method Computerized searching to identify reports of RCTs of DLX in adult, acute MDD patients permitted meta-analytic pooling to estimate overall response and remission rates, to compare mixed-model, repeated measures (MMRM) versus last-observations-carried-forward (LOCF) analytical methods, and to assess relations of DLX dose to efficacy and adverse outcomes.
Results We identified 17 RCTs involving 22 comparisons (DLX versus PBO [n= 17) and DLX versus an SRI [n = 16]), based on MMRM and LOCF methods that allowed estimates of response ( >= 50% improvement of depression scores) or remission (final depression score <= 7). There was a large overall DLX/PBO contrast (LOCF, RR = 1.42 [CI: 1.31-1.53], p < 0.0001, with a success rate of 65% [11/17]), and somewhat arger effects with MMRM in both response (MMRM: RR = 1.48 [95%Cl: 1.31-1.66] versus LOCF: RR = L41 [CI: 1.28-1.56]; NNT 4.8 versus 6.5) and remission (MMRM: RR = 1.61 [CI: 1.41-1.85] versus LOCF: RR = 1.44 [CI: 1.27-1.63]; NNT = 5.9 versus 8.9). Based on LOCF methods, dropout rates were similar with DLX and PBO (RR = 1.04 [CI: 0.94-1.15]); DLX response was dose-dependent (r = +0.72. p = 0.001), and RCT-dropout rates were inversely related to DLX dose, but possibly artifactually.
Limitations RCTs involving DLX are limited, with few direct comparisons to standard antidepressants.
Conclusions DLX has good evidence of efficacy in acute, adult MDD, especially at doses of 80-120 mg/day, but remains inadequately tested against standard alternatives. MMRM analyses yielded slightly superior FLX/PBO contrasts than older LOCF methods. Copyright (C) 2009 John Wiley & Sons, Ltd.

AB Objective This study sought to examine the effect of ziprasidone on olanzapine or clozapine-associated medical morbidity such as insulin resistance, diabetes mellitus (DM) and impaired fasting glucose, obesity, and hyperlipidemia in patients with schizophrenia or schizoaffective disorder.
Method This was a 6-week, open label trial of ziprasidone 160 mg/day added to a stable dose of olanzapine or clozapine in 21 schizophrenia or schizoalfective patients with DM, impaired fasting glucose, or insulin resistance.
Results Then olanzapine-treated subjects and I I clozapine-treated subjects were enrolled in the Study. There were no significant differences between the two groups at baseline for age, gender, education, ethnicity, BMI, cholesterol levels, or fasting glucose. At week 6. there were no significant changes in weight, BMI, cholesterol levels, or fasting glucose. There was no significant difference in psychotic, negative, or depressive symptoms. QTc: significantly increased at week 2 but not at week 6.
Conclusions The addition of 160 mg/day of ziprasidone was well tolerated but did not produce significant improvement in fasting glucose, insulin resistance, hyperlipidemia or lead to weight loss in olanzapine- or clozapine-treated subjects with schizophrenia or schizoaffective disorder.

AB We previously established parthenogenetic mouse embryonic stem cells (ESCs) and this study was subsequently conducted for elucidating the influence of oocyte parthenogenesis on gene expression profile of ESCs.
Gene expression of parthenogenetic ESC (pESC)-1 or pESC-2 was separately compared with that of two normally fertilized ESC (nfESC) lines (B6D2F1 and R1 strains), and quantification of mRNA expression was conducted for validating microarray data.
In two sets of comparison, reaction of 11 347 and 15 454 gene probes were altered by parthenogenesis, while strain difference changed the expression of 15 750 and 14 944 probes. Level of correlation coefficient was higher in the comparisons between normal fertilization and parthenogenesis (0.974-0.985) than in the comparisons between strains of nfESCs (0.97-0.971). Overall, the expression of 3276-3329 genes was changed after parthenogenesis, and 88% (96/109) of major functional genes differentially (P < 0.01) expressed in one comparison set showed the same change in the other. When we monitored imprinted genes, expression of nine paternal and eight maternal genes were altered after parthenogenesis and 88% (14/16) of these was confirmed by mRNA quantification.
The change in gene expression after parthenogenesis was similar to, or less than, the change induced by a strain difference under a certain genetic background. These results may suggest the clinical feasibility of parthenogenesis-derived, pluripotent cells.

AB In this paper, we propose a novel method for the registration of volumetric images of the brain that optimizes the alignment of both cortical and subcortical structures. In order to achieve this, relevant geometrical information is extracted from a surface-based morph and diffused into the volume using the Navier operator of elasticity, resulting in a volumetric warp that aligns cortical folding patterns. This warp field is then refined with an intensity driven optical flow procedure that registers noncortical regions, while preserving the cortical alignment. The result is a combined surface and volume morph (CVS) that accurately registers both cortical and subcortical regions, establishing a single coordinate system suitable for the entire brain.

AB The electrolarynx (EL) is a common rehabilitative speech aid for individuals who have undergone total laryngectomy, but they typically lack pitch control and require the exclusive use of one hand. The viability of using neck and face surface electromyography (sEMG) to control the onset, offset, and pitch of an EMG-controlled EL (EMG-EL) was studied. Eight individuals who had undergone total laryngectomy produced serial and running speech using a typical handheld EL and the EMG-EL while attending to real-time visual sEMG biofeedback. Running speech tokens produced with the EMG-EL were examined for naturalness by 10 listeners relative to those produced with a typical EL using a visual analog scale. Serial speech performance was assessed as the percentage of words that were fully voiced and pauses that were successfully produced. Results of the visual analog scale assessment indicated that individuals were able to use the EMG-EL without training to produce running speech perceived as natural as that produced with a typical handheld EL. All participants were able to produce running and serial speech with the EMG-EL controlled by sEMG from multiple recording locations, with the superior ventral neck or submental surface locations providing at least one of the two best control locations.

ID DIVERSITY; CHANNELS
AB In this paper, a number of ultrawideband (UWB) multiple-input multiple-output ( MIMO) spatial multiplexing systems are presented and their error performance is analysed. For both model-based and measured UWB channels, the performance of various MIMO detectors is evaluated under the multiband orthogonal frequency division multiplexing (MB-OFDM) regime. Contrary to expectation, the results demonstrate that significant spatial diversity can be extracted, in addition to linear data-rate scaling, despite the large frequency diversity inherent in the UWB channel. It is shown that nonlinear detection schemes with reasonable complexity can provide considerable diversity gain, in contrast to well-known linear receivers. Thus, the proposed UWB spatial multiplexing schemes not only increase the data rate but also provide significant diversity gain and improved error rate performance.

AB Zebrafish (Danio rerio) have a number of strengths as a host model for infection, including genetic tractability, a vertebrate immune system similar to that of mammals, ease and scale of laboratory handling, which allows analysis with reasonable throughput, and transparency, which facilitates visualization of the infection. With these advantages in mind, we examined whether zebrafish could be used to study Pseudomonas aeruginosa pathogenesis and found that infection of zebrafish embryos with live P. aeruginosa (PA14 or PAO1) by microinjection results in embryonic death, unlike infection with Escherichia coli or heat-killed P. aeruginosa, which has no effect. Similar to studies with mice, P. aeruginosa mutants deficient in type three secretion (pscD) or quorum sensing (lasR and mvfR) are attenuated in zebrafish embryos infected at 50 h postfertilization (hpf), a developmental stage when both macrophages and neutrophils are present. In contrast, embryos infected at 28 hpf, when only macrophages are initially present, succumb to lethal challenge with far fewer P. aeruginosa cells than those required for embryos infected at 50 hpf, are susceptible to infection with lasR and pscD deletion mutants, and are moderately resistant to infection with an mvfR mutant. Finally, we show that we can control the outcome of infection through the use of morpholinos, which allow us to shift immune cell numbers, or small molecules (antibiotics), which rescue embryos from lethal challenge. Thus, zebrafish are a novel host model that is well suited for studying the interactions among individual pathogenic functions of P. aeruginosa, the role of individual components of host immune defense, and small-molecule modulators of infection.

AB Background: The Short Inflammatory Bowel Disease Questionnaire (SIBDQ) is it written. self-administered instrument measuring quality of life in IBD. We assessed the validity of an interactive voice response system (IVRS) as a new mode of administering the SIBDQ.
Methods: An IVRS was designed using prerecorded questions to collect data via touchtone telephone. Subjects with Crohn's disease (CD) or ulcerative colitis (UC) were randomized into 2 groups With different orders of administration: written, self-administered followed by IVRS (S-I) or IVRS followed by written, self-administered (I-S). Half of the S-I group was also randomized to receive a second IVRS. Sixty-four subjects were studied: 30 in S-I. 34 in I-S.
Results: The mean SIBDQ scores were not different between written and IVRS modes (P = 0.26) with r = 0.93. IVRS scores were lower in active than inactive CID (36.1 +/- 9.6 versus 54.7 +/- 8.6, P < 0.001) and lower in active than inactive UC (40.8 +/- 9.6 versus 59.8 +/- 10.0. P < 0.001). Mean scores correlated highly with disease activity indices, and were not different between first and second IVRS administrations (P = 0.85) with r = 0.92. IVRS had excellent internal consistency (Cronbach alpha = 0.90).
Conclusions: IVRS administration of the SIBDQ yields results similar to written self-administration, with excellent procedural validity, test-retest reliability. and internal consistency.

AB In vivo imaging reveals how proteins and cells function as part of complex regulatory networks in intact organisms, and thereby contributes to a systems-level understanding of biological processes. However, the development of novel in vivo imaging probes remains challenging. Most probes are directed against a limited number of pre-specified protein targets; cell-based screens for imaging probes have shown promise, but raise concerns over whether in vitro surrogate cell models recapitulate in vivo phenotypes. Here, we rapidly profile the in vitro binding of nanoparticle imaging probes in multiple samples of defined target vs. background cell types, using primary cell isolates. This approach selects for nanoparticles that show desired targeting effects across all tested members of a class of cells, and decreases the likelihood that an idiosyncratic cell line will unduly skew screening results. To adjust for multiple hypothesis testing, we use permutation methods to identify nanoparticles that best differentiate between the target and background cell classes. (This approach is conceptually analogous to one used for high-dimensionality datasets of genome-wide gene expression, e.g. to identify gene expression signatures that discriminate subclasses of cancer.) We apply this approach to the identification of nanoparticle imaging probes that bind endothelial cells, and validate our in vitro findings in human arterial samples, and by in vivo intravital microscopy in mice. Overall, this work presents a generalizable approach to the unbiased discovery of in vivo imaging probes, and may guide the further development of novel endothelial imaging probes.

ID PERFORMANCE
AB Background: Traditionally, specific ventilators have been manufactured to only provide neonatal mechanical ventilation. However, many of the current generation of ICU ventilators also include a neonatal mode. Methods: Using the IngMar ASL5000 lung simulator the Puritan Bennett 840, the Maquet Servo i, the Viasys AVEA, the GE Engstrom, the Drager Evita XL and Babylog 8000 Plus were evaluated during assisted ventilation in the pressure assist/control mode. Three lung mechanics were set: resistance 50 cmH(2)O/L/s, compliance 2 mL/cmH(2)O; resistance 100 cmH(2)O/L/s, compliance 1 mL/cmH(2)O; and resistance 150 cmH(2)O/L/s, compliance 0.5 mL/cmH(2)O. A maximum negative pressure drop of 4 and 7 cmH(2)O was achieved during simulated inspirations. Each ventilator was evaluated with PEEP 5 cmH(2)O, peak pressure 20 cmH(2)O and inspiratory time 0.3 s and with PEEP 10 cmH(2)O, peak pressure 30 cmH(2)O and inspiratory time 0.4 s. Each ventilator setting was then repeated with a leak of 0.3 L/min at a constant pressure of 5 cmH(2)O. Results: Overall each of the 5 ICU ventilators responded faster or greater than the Babylog with respect to: pressure to trigger (except the Servo i), time to trigger (except the Evita XL), time between trigger and return of pressure to baseline, time from start of breath to 90% of peak pressure (except the Avea) and pressure time product of breath activation. Expiratory tidal volume was also greater with all ICU ventilators except the Avea. Variation in mechanics, leak, PEEP and muscular effort had little effect on these differences. Conclusion: All ICU ventilators tested were able to at least equal the performance of the Babylog 8000 Plus on all variables evaluated.

AB Purpose: Many methods exist in the literature for identifying PEEP to set in ARDS patients following a lung recruitment maneuver (RM). We compared ten published parameters for setting PEEP following a RM. Methods: Lung injury was induced by bilateral lung lavage in 14 female Dorset sheep, yielding a PaO(2) 100-150 mmHg at F(I)O(2) 1.0 and PEEP 5 cmH(2)O. A quasi-static P-V curve was then performed using the supersyringe method; PEEP was set to 20 cmH(2)O and a RM performed with pressure control ventilation (inspiratory pressure set to 40-50 cmH(2)O), until PaO(2) + PaCO(2) > 400 mmHg. Following the RM, a decremental PEEP trial was performed. The PEEP was decreased in 1 cmH(2)O steps every 5 min until 15 cmH(2)O was reached. Parameters measured during the decremental PEEP trial were compared with parameters obtained from the P-V curve. Results: For setting PEEP, maximum dynamic tidal respiratory compliance, maximum PaO(2), maximum PaO(2) + PaCO(2), and minimum shunt calculated during the decremental PEEP trial, and the lower Pflex and point of maximal compliance increase on the inflation limb of the P-V curve (Pmci,i) were statistically indistinguishable. The PEEP value obtained using the deflation upper Pflex and the point of maximal compliance decrease on the deflation limb were significantly higher, and the true inflection point on the inflation limb and minimum PaCO(2) were significantly lower than the other variables. Conclusion: In this animal model of ARDS, dynamic tidal respiratory compliance, maximum PaO(2), maximum PaO(2) + PaCO(2), minimum shunt, inflation lower Pflex and Pmci,i yield similar values for PEEP following a recruitment maneuver.

Diabetes is an important risk factor for cardiovascular disease, which is the leading cause of death in diabetic patients, and decreasing the incidence of diabetes may potentially reduce the burden of cardiovascular disease. This article discusses the clinical trial evidence for modalities associated with a reduction in the risk of new-onset diabetes, with a focus on the role of antihypertensive agents that block the renin-angiotensin system. Lifestyle interventions and the use of antidiabetic, anti-obesity, and lipid-lowering drugs are also reviewed. An unresolved question is whether decreasing the incidence of new-onset diabetes with non-pharmacologic or pharmacologic intervention will also lower the risk of cardiovascular disease. A large ongoing study is investigating whether the treatment with an oral antidiabetic drug or an angiotensin-receptor blocker will reduce the incidence of new-onset diabetes and cardiovascular disease in patients at high risk for developing diabetes.

AB Bariatric surgery is currently the most effective method to promote major, sustained weight loss. Roux-en-Y gastric bypass (RYGB), the most commonly performed bariatric operation, ameliorates virtually all obesity-related comorbid conditions, the most impressive being a dramatic resolution of type 2 diabetes mellitus (T2DM). After RYGB, 84% of patients with T2DM experience complete remission of this disease, and virtually all have improved glycemic control. Increasing evidence indicates that the impact of RYGB on T2DM cannot be explained by the effects of weight loss and reduced energy intake alone. Weight-independent antidiabetic actions of RYGB are apparent because of the very rapid resolution of T2DM ( before weight loss occurs), the greater improvement of glucose homeostasis after RYGB than after an equivalent weight loss from other means, and the occasional development of very late-onset, pancreatic beta-cell hyperfunction. Several mechanisms probably mediate the direct antidiabetic impact of RYGB, including enhanced nutrient stimulation of L-cell peptides ( for example, GLP-1) from the lower intestine, intriguing but still uncharacterized phenomena related to exclusion of the upper intestine from contact with ingested nutrients, compromised ghrelin secretion, and very probably other effects that have yet to be discovered. Research designed to prioritize these mechanisms and identify potential additional mechanisms promises to help optimize surgical design and might also reveal novel pharmaceutical targets for diabetes treatment.

AB Purpose: Radiation has many potential long-term effects on cancer survivors. Female cancer patients may experience decreased fertility depending on the site irradiated. Oncologists should be aware of these consequences and discuss options for fertility preservation before initiating therapy.
Methods and Materials: A comprehensive review of the existing literature was conducted. Studies reporting the outcomes for female patients treated with cranio-spinal, abdominal, or pelvic radiation reporting fertility, pregnancy, or neonatal-related outcomes were reviewed.
Results: Cranio-spinal irradiation elicited significant hormonal changes in women that affected their ability to become pregnant later in life. Women treated with abdomino-pelvic radiation have an increased rate of uterine dysfunction leading to miscarriage, preterm labor, low birth weight, and placental abnormalities. Early menopause results from low-dose ovarian radiation. Ovarian transposition may decrease the rates of ovarian dysfunction.
Conclusions: There is a dose-dependent relationship between ovarian radiation therapy (RT) and premature menopause. Patients treated with RT must be aware of the impact of treatment on fertility and explore appropriate options. (C) 2009 Elsevier Inc.

AB The design hypothesis, architectures, and computational modeling of a novel peptide-based nanoactuator are presented in this paper. We engineered the alpha-helical coiled-coil portion of the yeast transcriptional activator peptide called GCN4 to obtain an environmentally responsive nanoactuator. The dimeric coiled-coil peptide consists of two identical approximately 4.5 nm long and approximately 3 nm wide polypeptide chains. The actuation mechanism depends on the modification of electrostatic charges along the peptide by varying the pH of the solution resulting in the reversible movement of helices and, therefore, creating the motion of an actuator. Using molecular dynamics simulations we showed that pH changes led to a reversible opening of up to 1.5 nm which is approximately 150% of the initial separation of the nanoactuator. We also investigated the forces generated by the nanoactuator upon pH actuation, using a new method based on a modified steered molecular dynamics technique. Owing to its open and close motion resembling that of tweezers, the new nanoactuator can potentially be used as a nanogripper in various nanomanipulation tasks such as detection and removal of heavy metal ions during nanofabrication processes or as a molecular switch.

AB PURPOSE. To evaluate the effect of pupillary dilation on electronic-ETDRS visual acuity (EVA) in diabetic subjects and to assess postdilation EVA as a surrogate for predilation VA.
METHODS. DRCR.net-protocol refraction and EVA were measured before and after dilation in diabetic subjects by independent, masked examiners.
RESULTS. In 129 eyes of 66 subjects, the median (25th, 75th percentiles) predilation EVA score was 69 (54, 86) (Snellen-equivalent 20/40(-1) [20/80(-1), 20/20(-1)]). Predilation VA was >= 20/20, <20/20 to 20/40, <20/40 to 20/80, and <20/80 in 29%, 19%, 26%, and 26% of eyes, respectively. Median EVA change postdilation was -3 letters (-7, 0). The absolute change in EVA score was >= 15 letters (>= 3 ETDRS lines) in 9% of eyes and >= 10 letters (>= 2 ETDRS lines) in 19% of eyes. Extent of change (range +12 to -25 letters) was associated with baseline VA. No relationship was identified between EVA change and gender, race, lens status, refractive error, DR severity, or primary cause of vision loss.
CONCLUSIONS. In an optimized clinical trial setting, there is a decline in best corrected EVA after dilation in diabetic subjects. The large range and magnitude of VA change preclude using postdilation EVA as a surrogate for undilated VA. (Invest Ophthalmol Vis Sci. 2009; 50: 1580-1584) DOI: 10.1167/iovs.08-2426

AB PURPOSE. In the present study, the authors developed novel models to stimulate blood vessel formation (hemangiogenesis) versus lymphatic vessel formation (lymphangiogenesis) in the cornea.
METHODS. Micropellets loaded with high-dose (80 ng) or low-dose (12.5 ng) basic fibroblast growth factor (bFGF) were placed in BALB/c corneas. Angiogenic responses were analyzed by immunohistochemistry to quantify blood neovessels (BVs) and lymphatic neovessels (LVs) to 3 weeks after implantation. Areas covered by BV and LV were calculated and expressed as a percentage of the total corneal area (percentage BV and percentage LV). Hemangiogenesis (HA) and lymphangiogenesis (LA) were also assessed after antibody blockade of VEGFR-2 or VEGFR-3
RESULTS. Although high-dose bFGF stimulation induced a more potent angiogenic response, the relative LV (RLV = percentage LV/percentage BV X 100) was nearly identical with high- and low-doses of bFGF. Delayed LA responses induced 3 weeks after implantation of high-dose bFGF resulted in a lymphatic vessel-dominant phenotype. Interestingly, the blockade of VEGFR-2 significantly suppressed BV and LV. However, the blockade of VEGFR-3 inhibited only LV (P = 0.0002) without concurrent inhibition of BV (P = 0.79), thereby resulting in a blood vessel-dominant phenotype
CONCLUSIONS. An HA-dominant corneal phenotype can be obtained in BALB/c mice 2 weeks after implantation of an 80-ng bFGF micropellet with VEGFR-3 blockade. Alternatively, an LA-dominant corneal phenotype can be obtained 3 weeks after implantation of an 80-ng bFGF micropellet without supplementary modulating agents. These models will be useful in evaluating the differential contribution of BV and LV to a variety of corneal abnormalities, including transplant rejection, wound healing and microbial keratitis.

AB PURPOSE. Interphotoreceptor retinoid-binding protein (IRBP) has been considered essential for normal rod and cone function, as it mediates the transport of retinoids between the photoreceptors and the retinal pigment epithelium. This study was performed to determine whether mutations in the IRBP gene (RBP3) are associated with photoreceptor degeneration.
METHODS. A consanguineous family was ascertained in which four children had autosomal recessive retinitis pigmentosa (RP). Homozygosity mapping performed with SNP microarrays revealed only one homozygous region shared by all four affected siblings. Sequencing of RBP3, contained in this region, was performed in this family and others with recessive RP. Screening was also performed on patients with various other forms of retinal degeneration or malfunction.
RESULTS. Sequence analysis of RBP3 revealed a homozygous missense mutation (p. Asp1080Asn) in the four affected siblings. The mutation affects a residue that is completely conserved in all four homologous modules of the IRBP protein of vertebrate species and in C-terminal-processing proteases, photosynthesis enzymes found in bacteria, algae, and plants. Based on the previously reported crystal structure of Xenopus IRBP, the authors predict that the Asp1080-mediated conserved salt bridge that appears to participate in scaffolding of the retinol-binding domain is abolished by the mutation. No RBP3 mutations were detected in 395 unrelated patients with recessive or isolate RP or in 680 patients with other forms of hereditary retinal degeneration.
CONCLUSIONS. Mutations in RBP3 are an infrequent cause of autosomal recessive RP. The mutation Asp1080Asn may alter the conformation of the IRBP protein by disrupting a conserved salt bridge. (Invest Ophthalmol Vis Sci. 2009; 50: 1864-1872) DOI: 10.1167/iovs.08-2497

AB Context The Leapfrog Hospital Survey allows hospitals to self-report the steps they have taken toward implementing the Safe Practices for Better Healthcare endorsed by the National Quality Forum. The Leapfrog Group currently ranks hospital performance on the safe practices initiative by quartiles and presents this information to the public on its Web site. It is unknown how well a hospital's resulting Safe Practices Score (SPS) correlates with outcomes such as inpatient mortality.
Objective To determine the relationship between hospitals' SPSs and risk-adjusted inpatient mortality rates.
Design, Setting, and Participants Observational analysis of discharge data for all urban US hospitals completing the 2006 safe practices initiative and identifiable in the Nationwide Inpatient Sample. Leapfrog provided an SPS for each hospital as well as 3 alternative scores based on shorter versions of the original survey. Hierarchical logistic regression was used to determine the relationship between quartiles of SPS and risk-adjusted inpatient mortality, after adjusting for hospital discharge volume and teaching status. Subgroup analyses were performed using data from patients older than 65 years and patients with 5% or greater expected mortality risk.
Main Outcome Measures Inpatient risk-adjusted mortality by quartiles of survey score.
Results Of 1075 hospitals completing the 2006 Safe Practices Survey, 155 (14%) were identifiable in the National Inpatient Sample (1 772 064 discharges). Raw observed mortality in the primary sample was 2.09%. Fully adjusted mortality rates by quartile of SPS, from lowest to highest, were 1.97% (95% confidence interval [CI], 1.78%-2.18%), 2.04% (95% CI, 1.84%-2.25%), 1.96% (95% CI, 1.77%-2.16%), and 2.00% (95% CI, 1.80%-2.22%) (P=.99 for linear trend). Results were similar in the subgroup analyses. None of the 3 alternative survey scores was associated with risk-adjusted inpatient mortality, although P values for linear trends were lower (. 80, .20, and .11).

AB Background: Sleep disturbance in bipolar disorder can be both a risk factor and symptom of mood episodes. However, the associations among sleep and clinical characteristics, function, and quality of life in bipolar disorder have not been fully investigated.
Methods: The prevalence of sleep disturbance, duration, and variability, as well as their associations with mood, function, and quality of life, was determined from 2024 bipolar patients enrolled in the National Institute of Mental Health Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD).
Results: Analyses indicated that 32% of patients were classified as short sleepers, 39% normal sleepers, and 23% long sleepers. Overall, short sleepers demonstrated greater mood elevation, earlier age at onset, and longer illness duration compared to both normal and long sleepers. Both short and long sleepers had greater depressive symptoms, poorer life functioning, and quality of life compared to nor-mal sleepers.
Discussion: Sleep duration in bipolar disorder was associated with a more severe symptom presentation, whereas both short and long sleep duration are associated with poorer function and quality of life compared to normal sleep duration. Sleep disturbance could be a trait marker of bipolar disorder, though longitudinal assessments are warranted to assess potential Causal relations and the longer-term implications of sleep disturbance in bipolar disorder.

AB Background: This report describes baseline characteristics and functional outcomes of subjects who have prospectively observed subsyndromal symptoms after a major depressive episode (MDE).
Methods: All subjects were participants in the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD). We identified subjects with at least 2 years of observation whose prior or current episode was a MDE, and who were in a stable clinical state of either recovered (no more than 2 moderate symptoms for at least 8 weeks), a MDE by DSM-IV criteria, or with continued subsyndromal symptoms. The subsyndromal group was defined a priori as 3 or more moderate affective symptoms but without meeting diagnostic criteria for major depression.
Results: The final cohort included 1094 recovered, 112 subsyndromal, and 3 10 individuals in a MDE. The average time spent in each clinical status ranged from 120 to 132 days. The subsyndromal group was most similar to those in a MDE, differing only on the intensity of depressive symptoms and the number of work days missed due to ongoing symptoms. Reported sadness, inability to feel and lassitude were each associated with multiple measures of impairment.
Limitations: This study is limited by the cross-sectional approach to defining outcomes.
Conclusions: These findings are consistent with studies in unipolar major depression that indicate that functional impairment observed in the context of subsyndromal depressive symptoms is comparable to that of a full episode. This work underscores the need to include subsyndromal symptoms in study outcomes and to target full remission in clinical practice. (c) 2008 Elsevier B.V. All rights reserved.

TI The family myth: its deconstruction and replacement with a balanced
humanized narrative
SO JOURNAL OF ANALYTICAL PSYCHOLOGY
LA English
DT Article
DE family myth; humanized narrative; puer aeternus; transference resistance
AB According to Carl Jung the mythopoeic activities of the collective unconscious contribute to the trajectory of personal individuation (Segal 1998). The 'family myth' represents an imaginal narrative that emphasizes the importance of the family's founders, its collective values, and its position with respect to 'outsiders'. Sigmund Freud identified the importance of the Oedipal myth as the basis of nuclear family dynamics (Rudnytsky 1992); however, the 'myth of the family' represents in reality a 'family of myths', each emphasizing different elements of potential interpersonal dynamics. But whereas some myths foster the child's optimal separation from parental influence and promote the process of individuation, others tend to hinder development.
One potentially deleterious form of the family myth tends to serve the narcissistic wishes of parents in their bid to maintain influence over the child by fostering the archetypal features of their role. The children who are the targets of the myth are thwarted in their psychological development by virtue of the fact that they are denied the opportunity to humanize their archetypal projections onto their parent(s). The result is a persistence of childlike attitude with respect to people and situations that they encounter outside the nuclear family. The persistent constellation of the child archetype is evidenced by features of the puer aeternus, with deficits in the ability to work, form stable adult relationships, and create a separate nuclear family. The significance of this type of family myth in the inappropriate preservation of puerile attitudes is examined and the desire of the offending parent(s) to promote their own immortality is explored. The contribution of the myth to the transference and transference resistance is explicated and suggestions are offered with respect to how to approach this critical issue in analysis.

Optic nerve sheath diameter correlates with the presence and severity of acute mountain sickness: evidence for increased intracranial pressure. J Appl Physiol 106: 1207-1211, 2009. First published December 31, 2008; doi:10.1152/japplphysiol.01188.2007.-Increased intracranial pressure is suspected in the pathogenesis of acute mountain sickness (AMS), but no studies have correlated it with the presence or severity of AMS. We sought to determine whether increased optic nerve sheath diameter, a surrogate measure of intracranial pressure, is associated with the presence and severity of AMS. We performed a cross-sectional study of travelers ascending through Pheriche, Nepal (4,240 m), from March 3 to May 14, 2006. AMS was assessed using the Lake Louise score. Optic nerve sheath diameter was measured by ultrasound. Ultrasound exams were performed and read by separate blinded observers. Two-hundred eighty seven subjects were enrolled. Ten of these underwent repeat examination. Mean optic nerve sheath diameter was 5.34 mm [95% confidence interval (CI) 5.18-5.51 mm] in the 69 subjects with AMS vs. 4.46 mm (95% CI 4.39-4.54 mm) in the 218 other subjects (P < 0.0001). There was also a positive association between optic nerve sheath diameter and total Lake Louise score (P for trend < 0.0001). In a multivariate logistic regression model of factors associated with AMS, optic nerve sheath diameter was strongly associated with AMS (odds ratio 6.3; 95% CI, 3.7-10.8; P < 0.001). In 10 subjects with repeat examinations, change in Lake Louise score had a strong positive correlation with change in optic nerve sheath diameter (R(2) = 0.84, P < 0.001). Optic nerve sheath diameter, a proxy for intracranial pressure, is associated with the presence and severity of AMS.

AB Since the early studies on the resolution and reconstitution of the oxidative phosphorylation system from animal mitochondria, coupling factor B was recognized as an essential component of the machinery responsible for energy-driven ATP synthesis. At the phenomenological level, factor B was agreed to lie at the interface of energy transfer between the respiratory chain and the ATP synthase complex. However, biochemical characterization of the factor B polypeptide has proved difficult. It was not until 1990 that the N-terminal amino acid sequence of bovine mitochondrial factor B was reported, which followed, a decade later, by the report describing the amino acid sequence of full-length human factor B and its functional characterization. The present review summarizes the recent advances in structure-functional studies of factor B, including its recently determined crystal structure at 0.96 resolution. Ectopic expression of human factor B in cultured animal cells has unexpectedly revealed its role in shaping mitochondrial morphology. The supramolecular assembly of ATP synthase as dimer ribbons at highly curved apices of the mitochondrial cristae was recently suggested to optimize ATP synthesis under proton-limited conditions. We propose that the binding of the ATP synthase dimers with factor B tetramers could be a means to enhance the efficiency of the terminal step of oxidative phosphorylation in animal mitochondria.

Methods: Two cohorts of seventy-six matched patients, one with a fracture of the ulnar styloid base and the other with no ulnar fracture, were retrospectively analyzed by examining data gathered in a prospective study of plate-and-screw fixation of distal radial fractures. Patients were matched forage, sex, AO fracture type, and injury mechanism. The two cohorts were analyzed for differences in motion, grip strength, pain, the Gartland and Werley score, the DASH (Disabilities of the Arm, Shoulder and Hand) score, and the SF-36 (Short Form-36) score at six, twelve, and twenty-four months postoperatively. In a second analysis, sixty-four patients with <2 mm of displacement of a fracture of the ulnar styloid base were compared with forty-nine patients with greater displacement. Differences between cohorts and within cohorts over time were determined with use of regression analysis and the likelihood ratio test.
Results: No significant differences were found between patients with an unrepaired fracture of the ulnar styloid base and those with no ulnar fracture at any of the follow-up intervals. However, a trend was observed toward less grip strength at six months (71% [of that on the contralateral side] compared with 79%; mean difference, -8% [95% confidence interval = -15.3% to -0.6%]; p = 0.03) and less flexion (54 degrees compared with 59 degrees; mean difference, -5 degrees [95% confidence interval = -11.7 degrees to -0.8 degrees]; p = 0.02) and ulnardeviation (32 degrees compared with 36 degrees; mean difference, -4 degrees [95% confidence interval = -70 to -0.1 degrees]; p = 0.05) at twenty-four months after surgery in patients with an untreated fracture of the ulnar styloid base. There were no significant differences with regard to any tested outcome measure between the patients with >= 2 mm of displacement of an unrepaired fracture of the ulnar styloid base and those with less displacement.
Conclusions: An unrepaired fracture of the base of the uInar styloid does not appear to influence function or outcome after treatment of a distal radial fracture with plate-and-screw fixation, even when the uInar fracture was initially displaced >= 2 mm.

TI Contemporary Cruciate-Retaining Total Knee Arthroplasty with a Pegged
Tibial Baseplate Results at a Minimum of Ten Years
SO JOURNAL OF BONE AND JOINT SURGERY-AMERICAN VOLUME
LA English
DT Article
ID FOLLOW-UP; PATELLAR COMPONENT; SURVIVORSHIP; JOINT; STEM
AB Background: A total knee arthroplasty with a four-peg tibial baseplate is an uncommonly used contemporary design. Potential advantages of this baseplate include preservation of host bone, compatibility with minimally invasive techniques, and easier removal with revision techniques. The purpose of this study was to determine the long-term results of a contemporary total knee arthroplasty that included a four-peg tibial baseplate.
Methods: From February 1995 to December 1996, 127 total knee arthroplasties were performed by one surgeon in 115 patients with an average age of seventy years. Clinical and radiographic evaluations were performed with use of the Knee Society scoring system at a minimum of ten years following replacement. Complications were identified by means of chart review and screening for readmission at surrounding institutions.
Results: At the time of follow-up, at a minimum often years after the arthroplasty, thirty patients (with thirty-three involved knees) were documented to have died and four patients (with seven involved knees) could not be located. The next-of-kin of the patients who had died directly confirmed that the knee was unrevised at the time of death. Eighty-seven knees in eighty-one patients remained available for evaluation after a minimum of ten years of follow-up. Two knees had failed: one had a late infection at three years, and one had aseptic loosening at seven years. The rate of survival free of revision at ten years was 97%. Knee Society knee and function scores averaged 94 and 75 points, respectively. None of the remaining knees had radiographic evidence of loosening.
Conclusions: This study demonstrated excellent, durable clinical and radiographic results at a minimum of ten years after replacement with this cemented, modular, fixed-bearing, cruciate-retaining total knee prosthesis with a four-peg tibial baseplate. We believe that this design is an acceptable option for total knee arthroplasty.

AB Embryonic mesenchymal stem cells (eMSCs) were first derived from human embryonic stem cells (hESCs) overexpressing green fluorescence protein (GFP). They expressed CD29, CD44, CD73, CD105, CD166 and nestin, but not CD34, CD45, CD106 SSEA-4 or Oct3/4. Twenty million eMSCs in 1 mL of phosphate-buffered saline (PBS) were injected into the femoral veins of spontaneously hypertensive rats after transient middle cerebral artery occlusion. The migration and differentiation of the eMSCs in the ischemic brain were analyzed. The results revealed that eMSCs migrated to the infarction region and differentiated into neurons, which were positive for beta-tubulin III, microtubule-associated protein 2 (MAP2), HuC, neurofilament and human nuclear antibody, and to vascular endothelial cells, which were positive for von Willebrand factor (vWF). The transplanted cells survived in the infarction region for at least 4 weeks. Adhesive removal function significantly improved in the first week after cell transplantation, and rotarod motor function significantly improved starting from the second week. The infarction volume in the eMSC group was significantly smaller than that in the PBS control group at 4 weeks after infusion. The results of this study show that when administered intravenously, eMSCs differentiated into neuronal and endothelial cells, reduced the infarction volume, and improved behavioral functional outcome significantly in transient focal cerebral ischemia.

AB Background: Youths with pervasive developmental disorders (PDDs) often have symptoms that fail to respond to selective serotonin reuptake inhibitor (SSRI) treatment. These children may be given a subsequent trial of another SSRI. This study reports on the outcome of PDD youths who received a second SSRI trial after an initial treatment failure.
Methods: Clinic charts were reviewed for 22 outpatient youths with a DSM-IV diagnosis of a PDD who were treated with an SSRI after an initial failure with a previous SSRI. Response for the second SSRI trial was determined using the Clinical Global Impressions-Improvement Scale (CGI-I). Treatment indications, symptom severity, demographic data, and side effects were recorded.
Results: For the second SSRI trial, 31.8% of the subjects were rated as much improved on the CGI-I scale and determined to be responders, with 68.2% of the subjects demonstrating activation side effects. 90% of subjects demonstrated activation side effects when data from both SSRI trials were combined. There were no statistically significant associations between outcome of the second SSRI trial and clinical/demographic variables.
Conclusions: A second trial of an SSRI after an initial SSRI treatment failure was often unsuccessful in children and adolescents with PDDs. Activation side effects were common. Because alternative treatments in this population are limited, a second trial of an SSRI may still be considered. The study was limited by its retrospective design and by its small sample size.

AB Background: In clinical practice, bone mineral density (BMD) determined by dual-energy x-ray absorptiometry is used to monitor response to osteoporosis therapy. However, 1 to 2 yr are usually required to assess patients' BMD responses. The possibility of earlier indicators of a response or nonresponse to treatment, such as changes in bone turnover markers (BTMs), is of interest to physicians and patients.
Methods: In this post hoc analysis of women treated with once-weekly bisphosphonates, we examined the association of tertile percentage change from baseline in BTMs at 3 or 6 months and association of several baseline clinical characteristics with 24-month percentage change from baseline in BMD and with percentage of patients showing BMD nonresponse ( defined as BMD loss at two or more of four sites) at 24 months. Multivariable analysis was performed to determine which factors were independently associated with BMD nonresponse.
Results: Patients in the tertile with the greatest decrease in each of the BTMs had the greatest mean increase in BMD and the lowest percentage of BMD nonresponders at 24 months. Several characteristics were independently associated with BMD nonresponse, including smaller 3-month reductions from baseline in serum C-terminal telopeptide of type 1 collagen, bone-specific alkaline phosphatase, and N-terminal propeptide of type 1 procollagen; younger age of menopause; a family history of osteoporosis; and higher baseline trochanteric BMD. Baseline BTMs were not predictive of 24-month BMD response to therapy. The strongest associations were for changes in BTMs with treatment.
Conclusion: In groups of patients, short-term changes in markers of bone turnover appear to be predictors of longer term BMD response and nonresponse to bisphosphonate therapy. (J Clin Endocrinol Metab 94: 1097-1103, 2009)

AB Context: Postmenopausal women have greater visceral adiposity compared with premenopausal women. Adipokines are associated with increased adiposity, insulin resistance, and atherosclerosis.
Objective: The objective of the study was to assess changes in adipokines and inflammatory markers through the menopausal transition and correlate them with changes in visceral adiposity.
Design and Setting: This was a prospective cohort study of women through the menopausal transition conducted at the University of Washington.
Participants: Sixty-nine healthy women were followed up longitudinally from premenopausal (aged 45-55 yr) to postmenopausal status (aged 49-60 yr).
Outcome: On premenopausal and postmenopausal visits, fasting blood was drawn for adiponectin, leptin, serum amyloid A (SAA), C-reactive protein (CRP), monocyte-chemotactic protein-1, tissue plasminogen activator antigen (tPA), IL-6, and TNF-alpha. Body composition measures were assessed by body mass index, whole-body dual x-ray absorptiometry scan, and computed tomography scan of the abdomen at the lumbar 4-5 level.
Results: Women had a statistically significant increase in SAA, tPA, monocyte-chemotactic protein-1, and adiponectin between the two measurement occasions (P = 0.04, P = 0.02, P = 0.001, and P < 0.001, respectively). The increase in intraabdominal fat was correlated positively with the change in SAA (r = 0.31, P = 0.02), CRP (r = 0.56, P < 0.001), tPA (r = 0.40, P = 0.002), and leptin (r = 0.41, P = 0.002) and negatively correlated with the change in adiponectin (r = -0.37, P = 0.005). After adjustment for change in sc abdominal fat, the correlation between change in CRP, tPA, leptin, and adiponectin remained significantly associated with change in intraabdominal fat.
Conclusions: Women going through the menopausal transition have deleterious changes in inflammatory markers and adipokines that correlate with increased visceral adiposity. (J Clin Endocrinol Metab 94: 1104 - 1110, 2009)

AB Context: Leptin deficiency is associated with dyslipidemia and insulin resistance in animals and humans with lipoatrophy; leptin replacement ameliorates these abnormalities.
Objective: The objective of the study was to evaluate the effects of leptin therapy in lipoatrophic HIV-infected patients with dyslipidemia and hypoleptinemia.
Design: This was a 6-month, open-label, proof-of-principle pilot study.
Setting: Metabolicward studies were performed before and 3 and 6 months after leptin treatment.
Participants: Participants included eight HIV-infected men with lipoatrophy, fasting triglycerides greater than 300 mg/dl, and serum leptin less than 3 ng/ml.
Intervention: Recombinant human leptin was given by sc injection (0.01 mg/kg and 0.03 mg/kg twice daily for successive 3 month periods).
Outcome Measures: Measuresincluded fat distribution by magnetic resonance imaging and dual-energy X-ray absorptiometry; fasting lipids; insulin sensitivity by euglycemic hyperinsulinemic clamp; endogenous glucose production, gluconeogenesis, glycogenolysis, and whole-body lipolysis by stable isotope tracer studies; oral glucose tolerance testing; liver fat by proton magnetic resonance spectroscopy; and safety.
Results: Visceral fat decreased by 32%(P = 0.001) with no changes in peripheral fat. There were significant decreases in fasting total (15%, P = 0.012), direct low-density lipoprotein (20%, P = 0.002), and non-high-density lipoprotein (19%, P = 0.005) cholesterol. High-density lipoprotein cholesterol increased. Triglycerides, whole-body lipolysis, and free fatty acids decreased during fasting and hyperinsulinemia. Fasting insulin decreased. Endogenous glucose production decreased during fasting and hyperinsulinemia, providing evidence of improved hepatic insulin sensitivity. Leptin was well tolerated but decreased lean mass.
Conclusions: Leptin treatment was associated with marked improvement in dyslipidemia. Hepatic insulin sensitivity improved and lipolysis decreased. Visceral fat decreased with no exacerbation of peripheral lipoatrophy. Results from this pilot study suggest that leptin warrants further study in patients with HIV-associated lipoatrophy.

AB lContext: GH secretion declines with age, possibly contributing to reduced muscle mass, strength, and function. GH secretagogues (GHS) may increase muscle mass and physical performance.
Objectives/Design: We conducted a randomized, double-masked, placebo-controlled, multicenter study to investigate the hormonal, body composition, and physical performance effects and the safety of the orally active GHS capromorelin in older adults with mild functional limitation.
Intervention/Participants: A total of 395 men and women aged 65-84 yr were randomized for an intended 2 yr of treatment to four dosing groups (10 mg three times/week, 3 mg twice a day, 10 mg each night, and 10 mg twice a day) or placebo. Although the study was terminated early according to predetermined treatment effect criteria, 315 subjects completed 6 months of treatment, and 284 completed 12 months.
Results: A sustained dose-related rise in IGF-I concentrations occurred in all active treatment groups. Each capromorelin dose prompted a rise in peak nocturnal GH, which was greatest with the least frequent dosing. At 6 months, body weight increased 1.4 kg in subjects receiving capromorelin and decreased 0.2 kg in those receiving placebo (P = 0.006). Lean body mass increased 1.4 vs. 0.3 kg (P = 0.001), and tandem walk improved by 0.9 sec (P = 0.02) in the pooled treatment vs. placebo groups. By 12 months, stair climb also improved (P = 0.04). Adverse events included fatigue, insomnia, and small increases in fasting glucose, glycosylated hemoglobin, and indices of insulin resistance.
Conclusions: In healthy older adults at risk for functional decline, administration of the oral GHS capromorelin may improve body composition and physical function. (J Clin Endocrinol Metab 94: 1198-1206, 2009)

DEHYDROEPIANDROSTERONE; SECRETION; CORTISOL
AB Context: Anorexia nervosa is characterized by hypogonadism and relative hypercortisolemia. We have demonstrated that free testosterone levels are low in women with anorexia nervosa, with the lowest levels in those receiving oral contraceptives (OCPs), and that dehydroepiandrosterone (DHEA) sulfate is reduced only in those receiving OCPs.
Objective: The aim of the study was to determine whether adrenal steroidogenesis dysregulation contributes to decreased androgen levels in anorexia nervosa.
Design and Setting: We conducted a cross-sectional study in a General Clinical Research Center.
Study Participants: We studied 20 women with anorexia nervosa [10 women with anorexia nervosa receiving OCPs (AN+E) and 10 not receiving OCPs (AN+E)] and 20 healthy controls [10 healthy controls receiving OCPs (HC+E) and 10 not receiving OCPs (HC-E)].
Main Outcome Measures: We measured DHEA and cortisol levels in response to 250-mu g cosyntropin stimulation after 1-mg overnight dexamethasone suppression.
Results: Mean basal and stimulated, peak stimulated, and area under the curve (AUC) cortisol levels were higher in AN-E than HC-E, but mean basal and stimulated, peak and AUCDHEA were comparable. Mean AUC and peak cortisol were higher and DHEA AUC was lower in AN+E than AN-E. However, after controlling for cortisol binding globulin levels, peak and AUC cortisol were comparable between AN+E and AN-E. After controlling for albumin levels, AUC DHEA was comparable between AN+E and AN-E.
Conclusions: Adrenal glucocorticoid and androgen precursor secretion are dissociated in anorexia nervosa, with relative hypercortisolemia and a preservation of DHEA secretion. Reduced DHEA response to cosyntropin in women receiving OCPs is attributable to decreased albumin levels. In the setting of relative hypercortisolemia, reduced adrenal androgen precursor secretion is not a mechanism underlying low testosterone levels in anorexia nervosa.

AB Aim: The aim of the study was to use hospitalization data for the analysis of inflammatory bowel disease time trends in the United States.
Methods: US hospital utilization data were available for individual years from 1970 to 2004 through the National Hospital Discharge Survey. Age-specific rates of hospitalization were Calculated for consecutive 5-year periods.
Results: An increase in the rates of hospitalization for Crohn's disease was most pronounced in the age group 65+ followed by the age group 45 to 64. By contradistinction, the rates in the youngest age group 0 to 44 stayed largely unchanged. In ulcerative colitis, a significant increase in hospitalization rates was limited to the oldest age group, whereas the rates in the middle and young age group remained unchanged.
Conclusions: Extrapolation of the current trends suggests that in the future the hospitalization for inflammatory bowel disease may start to level off. This may occur earlier and be more pronounced in younger age groups and patients with ulcerative colitis than Crohn's disease.

AB Schizophrenia is a severe disorder that disrupts the function of multiple brain systems, resulting in impaired social and occupational functioning. The etiology and pathogenesis of schizophrenia appear to involve the interplay of a potentially large number of genetic liabilities and adverse environmental events that disrupt brain developmental pathways. In this Review, we discuss a strategy for determining how particular common and core clinical features of the illness are associated with pathophysiology in certain circuits of the cerebral cortex. The identification of molecular alterations in these circuits is providing critical insights for the rational development of new therapeutic interventions.

AB Acute megakaryoblastic leukemia (AMKL) is a font of acute myeloid leukemia (AML) associated with a poor prognosis. The genetics and pathophysiology of AMKL are not well understood. We generated a knockin mouse model of the one twenty-two-megakaryocytic acute leukemia (OTT-MAL) fusion oncogene that results from the t(1;22)(p13;q13) translocation specifically associated with a subtype of pediatric AMKL. We report here that OTT-MAL expression deregulated transcriptional activity of the canonical Notch signaling pathway transcription factor recombination signal binding protein for immunoglobulin K J region (RBPJ) and caused abnormal fetal megakaryopoiesis. Furthermore, cooperation between OTT-MAL and an activating mutation of the thrombopoietin receptor myeloproliferative leukemia virus oncogene (MPL) efficiently induced a short-latency AMKL that recapitulated all the features of human AMKL, including megakaryoblast hyperproliferation and maturation block, thrombocytopenia, organomegaly, and extensive fibrosis. Our results establish that concomitant activation of RBPJ (Notch signaling) and MPL (cytokine signaling) transforms cells of the megakaryocytic lineage and suggest that specific targeting of these pathways could be of therapeutic value for human AMKL.

AB Elevated plasma concentrations of HDL cholesterol (HDL-C) are associated with protection from atherosclerotic cardiovascular disease. Animal models indicate that decreased expression of endothelial lipase (LIPG) is inversely associated with HDL-C levels, and genome-wide association studies have identified LIPG variants as being associated with HDL-C levels in humans. We hypothesized that loss-of-function mutations in LIPG may result in elevated HDL-C and therefore performed deep resequencing of LIPG exons in cases with elevated HDL-C levels and controls with decreased HDL-C levels. We identified a significant excess of nonsynonymous LIPG variants unique to cases with elevated HDL-C. In vitro lipase activity assays demonstrated that these variants significantly decreased endothelial lipase activity. In addition, a meta-analysis across 5 cohorts demonstrated that the low-frequency Asn396Ser variant is significantly associated with increased HDL-C, while the common Thr111Ile variant is not. Functional analysis confirmed that the Asn396Ser variant has significantly decreased lipase activity both in vitro and in vivo, while the Thr111Ile variant has normal lipase activity. Our results establish that loss-of-function mutations in LIPG lead to increased HDL-C levels and support the idea that inhibition of endothelial lipase may be an effective mechanism to raise HDL-C.

AB BACKGROUND: Aggressive treatment of low-density lipoprotein cholesterol (LDL-C) fails to prevent most cardiovascular (CV) events. Concurrent treatment of LDL-C, high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG) should be considered in patients with dyslipidemia.
OBJECTIVE: The efficacy and safety of a proprietary niacin extended-release and simvastatin (NER/S) combination were compared to atorvastatin monotherapy in a Multicenter, Prospective, Randomized (3:2), Open-label. Blinded Endpoint (PROBE) study.
METHODS: Following >= 4 weeks without lipid-modifying therapies, 193 patients with dyslipidemia were treated with NER/S (n = 114 1000/40 mg/day, weeks 1 to 4 2000/40 mg/day weeks 5 to 12) or atorvastatin (n = 79: 40 mg/day, weeks 1 to 12).
RESULTS: Compared to atorvastatin, NER/S had a larger beneficial effect oil HDL-C (primary end point: 30.1 +/- 2.3% and 9.4 +/- 2.6%, respectively P <.001), TG (P =.02) and lipoprotein(a) (Lp[a]: P <.001), and similar effects on LDL-C and non-HDL-C. Two-thirds of patients treated with NER/S concurrently attained LDL-C (CV risk-adjusted goals), HDL-C (>= 40 mg/dL), and TG (< 150 mg/dL) targets, compared to one-third of patients treated with atorvastatin (P <.001). Flushing was the most common treatment-emergent adverse event (TEAE) (67.5% NER/S and 10.1% atorvastatin P <.001). Seventy-five percent Of flushing episodes were mild to moderate. More patients treated with NER/S discontinued due to TEAEs (21.1% and 3.8%; P <.001); the most common TEAE was flushing.
CONCLUSION: Compared to atorvastatin, NER/S provided Superior improvements in HDL-C, TG. and Lp(a) and comparable improvements in non-HDL-C and LDL-C. Treatment with NER/S should be considered for patients with dyslipidemia requiring comprehensive lipid control. (c) 2009 National Lipid Association. All rights reserved.

AB Methicillin-resistant Staphylococcus aureus (MRSA) has emerged as an important cause of skin and soft-tissue infections (SSTI). The understanding of the molecular epidemiology and virulence of MRSA continues to expand. From January 2005 to December 2005, we screened soldiers for MRSA nasal colonization, administered a demographic questionnaire, and monitored them prospectively for SSTI. All MRSA isolates underwent molecular analysis, which included pulsed-filed gel electrophoresis (PFGE) and PCR for Panton-Valentine leukocidin (PVL), the arginine catabolic mobile element (ACME), and the staphylococcal cassette chromosome mec (SCCmec). Of the 3,447 soldiers screened, 134 (3.9%) had MRSA colonization. Of the 3,066 (89%) who completed the study, 39 developed culture-confirmed MRSA abscesses. Clone USA300 represented 53% of colonizing isolates but was responsible for 97% of the abscesses (P < 0.001). Unlike colonizing isolates, isolates positive for USA300, PVL, ACME, and type IV SCCmec were significantly associated with MRSA abscess isolates. As determined by multivariate analysis, risk factors for MRSA colonization were a history of SSTI and a history of hospitalization. Although various MRSA strains may colonize soldiers, USA300 is the most virulent when evaluated prospectively, and PVL, ACME, and type IV SCCmec are associated with these abscesses.

AB Purpose
To determine if maintenance rituximab (MR) after standard chemotherapy improves progression-free survival (PFS) in advanced-stage indolent lymphoma.
Patients and Methods
Patients with stage III-IV indolent lymphoma with responding or stable disease after cyclophosphamide, vincristine, and prednisone (CVP) chemotherapy were stratified by initial tumor burden, residual disease after CVP (minimal or gross), and histology, and randomly assigned to observation (OBS) or MR 375 mg/m(2) once per week for 4 weeks every 6 months for 2 years. PFS was the primary end point.
Results
Three hundred eleven (282 with follicular lymphoma) evaluable patients who received CVP were randomly assigned to OBS (n = 158) or MR (n = 153). Best response improved in 22% MR versus 7% OBS patients (P = .00006). Toxicity was minimal in both study arms. Three-year PFS after random assignment was 68% MR versus 33% OBS (hazard ratio [HR] = 0.4; P = 4.4 x 10(-1)0 [all patients]) and 64% MR v 33% OBS ( HR = 0.4; P = 9.2 x 10(-8) [patients with follicular lymphoma]). There was an advantage for MR regardless of Follicular Lymphoma International Prognostic Index score, tumor burden, residual disease, or histology. In multivariate analysis of MR patients, minimal disease after CVP was a favorable prognostic factor. OS at 3 years was 92% MR versus 86% OBS (HR = 0.6; log-rank one-sided P = .05) and, among patients with follicular lymphoma, OS was 91% MR versus 86% (HR = 0.6; log-rank one-sided P = .08). A trend favoring MR was observed among patients with high tumor burden (log-rank one-sided P = .03).
Conclusion
The E1496 study provides the first phase III data in untreated indolent lymphoma that MR after chemotherapy significantly prolongs PFS.

AB Purpose
Transplantation of hematopoietic stem cells from an unrelated donor (URD) is an option for many patients who do not have an HLA-identical sibling donor (MSD). Current criteria for the selection of URDs include consideration for HLA alleles determined by high resolution typing methods, with preference for allele-matched donors. However, the utility and outcome associated with transplants from URDs compared with those from MSDs remains undefined.
Patients and Methods
We examined clinical outcome after patients received bone marrow transplants (BMTs) from MSDs; HLA-A, -B, -C, and DRB1 allele-matched URDs (8/8); and HLA-mismatched URDs in a homogeneous population of patients with chronic myeloid leukemia (CML) in first chronic phase (CP1) where a strong allogeneic effect and hence a lower risk of relapse is anticipated. Transplantation outcomes were compared between 1,052 URD and 3,514 MSD BMT recipients with CML in CP1.
Results
Five-year overall survival and leukemia-free survival (LFS) after receipt of BMTs from 8/8 matched URDs were worse than those after receipt of BMTs from MSDs (5-year survival, 55% v 63%; RR, 1.35; 95% CI, 1.17 to 1.56; P < .001; LFS, 50% v 55%; RR, 1.21; 95% CI, 1.06 to 1.40; P = .006). Survival was progressively worse with greater degrees of mismatch. Similar and low risk of relapse were observed after receipt of transplant from either MSD or URD.
Conclusion
In this homogeneous cohort of good risk patients with CML in CP1, 5-year overall survival and LFS after receipt of transplant from 8/8 allele-matched donors were modestly though significantly worse than those after receipt of transplant from MSDs. Additive adverse effects of multilocus mismatching are not well tolerated and should be avoided if possible.

ID OPIOID-INDUCED CONSTIPATION; ORAL NALOXONE; ANALGESIA; PATIENT
AB Background: Opiates are the mainstay of analgesia in the intensive care unit (ICU). Unfortunately, constipation is a common adverse effect associated with opioid use. Naloxone is a pure opiate antagonist that is frequently utilized in practice for the prophylaxis or treatment of opiate-induced constipation in the ICU. Despite extensive first pass metabolism in the liver there remains the potential for opiate reversal after oral administration. We sought to assess the safety of enteral naloxone in the ICU for the treatment of opiate-induced constipation.
Methods: Patients who were ordered enteral naloxone while in the ICU were identified through the Pharmacy's computer system. Patients were included in the data analysis if they had received at least one dose of enteral naloxone and had received standing opiates for at least 48 h prior to the initial naloxone dose. Patients were excluded from data analysis if the Richmond agitation-sedation scale (RASS) score was not utilized, they were paralysed or the medical record indicated that extubation was planned within the following 24 h. Data points were recorder at the following times with respect to each naloxone dose administered; time -2, -1, 0, 1, 2 and 4 h. The following data points were collected before and after each naloxone dose; blood pressure, heart rate, respiratory rate, RASS score, pain assessment score (recorded as present or absent), midazolam dose, propofol dose and fentanyl dose. In order to assess for possible opiate reversal the peak fentanyl, propofol and midazolam dose, vital sign value, RASS score and pain score were compared before and after each dose of naloxone.
Results: The mean naloxone dose was 3.6 +/- 0.9 mg. There was no significant change in RASS score around the naloxone doses, -2.9 +/- 1.4 before and -2.8 +/- 1.6 after (P = 0.28). There were no significant changes in mean fentanyl, propofol or midazolam dose around naloxone administration. There were also no significant changes in heart rate, blood pressure and respiratory rate or in the presence of pain.
Conclusion: These results demonstrate that the administration of enteral naloxone to patients on intravenous opiates in the ICU setting was not associated with changes in sedation score, vital signs, fentanyl dose, midazolam dose or propofol dose.

TI Impact of Antidepressant Continuation After Acute Positive or Partial
Treatment Response for Bipolar Depression: A Blinded, Randomized Study

AB Objective: To assess long-term outcome in bipolar disorder, subjects were prospectively followed after receiving acute treatment for bipolar depression.
Method: Eighty-three outpatients with DSM-IV bipolar depression who were enrolled between March 1996 and November 2002 and were treated in a 10-week acute double-blind antidepressant treatment trial agreed to participate in a 1-year double-blind continuation of their medication. In the acute antidepressant treatment trial, subjects were treated with a mood stabilizer plus 1 of 3 randomly assigned antidepressants. Sixty-one subjects had attained an acute positive antidepressant response (50% improvement on the Inventory for Depressive Symptomatology [IDS] or 2-point improvement on the Clinical Global Impression for Bipolar Disorder [CGI-BP]) and 22 subjects achieved only acute partial improvement at the end of the 10-week acute trial. In the blinded continuation phase immediately following the acute trial, subjects continued on the same medications and were rated monthly for up to I year using the IDS, CGI-BP, and the Young Mania Rating scale.
Results: At study endpoint, 42 (69%) of the 61 acute positive responders maintained positive response and 32 (53%) achieved remission. Compared to the acute positive responders, 6 (27%) of the 22 acute partial responders had achieved positive treatment response at study endpoint (p <.001). Eight acute positive responders (13%) and 5 acute partial responders (22%) developed mania.
Conclusion: Patients who achieve a positive acute antidepressant response to 10 weeks of antidepressant treatment adjunctive to a mood stabilizer will probably maintain response with the same continued treatment. Patients who achieve only a partial acute antidepressant response are less likely to further improve when the same treatment is sustained. The switch rate into mania for patients being treated with an antidepressant adjunctive to a mood stabilizer is not higher than the reported rate for patients on mood stabilizer monotherapy.

VALIDATION; IMIPRAMINE
AB Background: Subsyndromal symptoms of depression (SSD) in older outpatients with schizophrenia are common and clinically important. While many physicians prescribe antidepressants to patients with schizophrenia and schizoaffective disorder who have SSD, evidence for their effectiveness and safety has been meager. We describe a randomized placebo-controlled trial of citalopram in 198 patients.
Method: Participants in this 2-site study, conducted from September 1, 200 1, to August 31, 2007, were men and women with DSM-IV schizophrenia or schizoaffective disorder who were 40 years of age or older and who met study criteria for SSD. Patients were randomly assigned to flexible-dose treatment with citalopram or placebo augmentation of their current antipsychotic medication. Analysis of covariance was used to compare improvement in scores on the Hamilton Rating Scale for Depression and Calgary Depression Rating Scale between treatment groups; secondary efficacy analyses compared improvement in several other dimensions of schizophrenia.
Results: Augmentation with citalopram was significantly more effective than with placebo in improving depressive (p = .002) and negative (p = .049) symptoms, mental functioning (p = .000), and quality of life (p = .046). There were no significant differences between citalopram and placebo in suicidal ideation, positive symptoms, cognition, general medical health, physical functioning, or symptoms of movement disorders. No adverse events were more frequent in participants receiving citalopram than in those receiving placebo, and only 4 participants from each treatment group terminated early because of side effects.
Conclusions: Subsyndromal symptoms of depression in middle aged and older patients with schizophrenia responded to treatment with citalopram with lessening of depressive symptoms and improved functioning and quality of life. It may be important for clinicians to identify and treat SSD in middle-aged and older patients with chronic schizophrenia.

AB Olanzapine treatment has been associated with clinically meaningful weight increases, hypertriglyceridemia, insulin resistance, and diabetes mellitus. There are few options for olanzapine responders who fail other antipsychotic agents. Aripiprazole is a potent (high-affinity) partial agonist at D(2) and 5-HT(1A) receptors and a potent antagonist at 5-HT(2A) receptor and is associated with less weight gain than olanzapine. We report the results of a 10-week placebo-controlled, double-blind crossover study that examined 15 mg/d aripiprazoles, effects on weight, lipids, glucose metabolism, and psychopathology in overweight and obese schizophrenia and schizoaffective disorder subjects treated with a stable dose of olanzapine. During the 4 weeks of aripiprazole treatment, there were significant decreases in weight (P = 0.003) and body mass index (P = 0.004) compared with placebo. Total serum cholesterol (P = 0.208), high-density lipoprotein cholesterol (HDL-C; P = 0.99), HDL-2 (P = 0.08), HDL-3 (P = 0.495), and low-density lipoprotein cholesterol (P = 0.665) did not change significantly comparing aripiprazole treatment to placebo treatment. However, total serum triglycerides (P = 0.001), total very low-density lipoprotein cholesterol (VLDL-C; P = 0.01), and VLDL-1C and VLDL-2C (P = 0.012) decreased significantly during the aripiprazole treatment phase. The VLDL-3C tended lower during aripiprazole, but the decrease was not significant (P = 0.062). There was a decrease in C-reactive protein comparing aripiprazole treatment to placebo, although it did not reach significance (P = 0.087). The addition of aripiprazole to a stable dose of olanzapine was well tolerated and resulted in significant improvements on several outcome measures that predict risk for medical morbidity.

ID ANIMAL-TYPE MELANOMA; MALIGNANT-MELANOMA; NEOPLASMS; TUMOR
AB The term 'pigmented epithelioid melanocytoma (PEM)' was recently used for borderline melanocytic tumor/low-grade melanoma including cases previously diagnosed as human animal-type melanoma and epithelioid blue nevus. No Japanese cases have been reported.
We reviewed 219 cases previously diagnosed as blue nevus in Japan. Common blue nevus was identified in 154 cases and cellular blue nevus in 65 cases.
We have found two Japanese cases of PEM previously diagnosed as cellular blue nevus. Two patients were female. The age at presentation was 32 and 28 years. Two lesions were on the buttock. Two cases fulfilled histological criteria proposed for PEM. There is no evidence of recurrence or metastases.
PEM is a distinct melanocytic tumor and the unifying diagnostic term. PEM is present in Japanese, but these cases may be previously diagnosed as cellular blue nevus. Japanese pathologists should recognize a new concept of PEM, and when they make a diagnosis of PEM, they should be recommended sentinel lymph node sampling.

AB Kallikrein-4 (KLK4) is a serine protease expressed during enamel maturation, and proteolytic processing of the enamel matrix by KLK4 is critical for proper enamel formation. KLK4 is secreted as an inactive zymogen (pro-KLK4), and identification of its activator remains elusive. Dipeptidyl peptidase I (DPPI) is a cysteine aminopeptidase that can activate several serine proteases. In this study, we sought to examine DPPI expression in mouse enamel organ and determine if DPPI could activate KLK4. Real-time PCR showed DPPI expression throughout amelogenesis, with highest expression at maturation, and immunohistochemical staining of mouse incisors confirmed DPPI expression by ameloblasts. We demonstrate in vitro that DPPI activates pro-KLK4 to cleave a fluorogenic peptide containing a KLK4 cleavage site. Examination of mature enamel from DPPI null mice by FTIR showed no significant accumulation of protein; however, microhardness testing revealed that loss of DPPI expression significantly reduced enamel hardness.

AB Transdifferentiation of cells from a patients own liver into pancreatic beta-cells could be useful for beta-cell replacement. We hypothesized that intrahepatic biliary epithelial cells (IHBECs) could become a new source of insulin-producing cells. IHBECs isolated from adult mice were expanded using our novel culture method termed, collagen-embedded floating culture method (CEFCM). With CEFCM, IHBECs formed three-dimensional ductal cysts and rapidly expanded their number by about 15-fold within 2 weeks. Over 90% of cells were positive for cytokeratin 7 and 19. At day 14, IHBECs were transfected with adenoviral (Ad)- pancreas duodenum homeobox 1 (Pdx-1), NeuroD or Pdx-1/VP16. After 7 additional days in serum- and insulin-free differentiation medium (DM), cell phenotypes were determined by RT-PCR, immunostaining and ELISA for insulin. In DM control IHBECs started to express some endocrine progenitor genes (Neurog3, NeuroD, Nkx6.1, and Pdx-1) but lacked insulin gene (Ins) mRNA. Transduced expression of PDX-1, NEUROD or PDX-1/VP16 led to expression of not only INS but also GLUT2 and prohormone convertase 1 and 2. About 3% of 4000 cells counted in PDX-1/VP16 transduced cultures stained strongly for C-peptide Suggesting that a subpopulation may have the capacity for differentiation. Transduced cells released insulin (Ad-PDX-1 0.08 +/- 0.05, Ad-NEUROD 0.33 +/- 0.09, Ad-PDX-1/VP16 0.37 +/- 0-14 ng/1 x 10(5) cells after 48 h in Culture). IHBECs can be markedly expanded, and then with molecular manipulation a subpopulation of these cells can differentiate towards a beta-cell phenotype. This approach may lead to a new source of beta-cells that can be used for transplantation in diabetes. Journal of Endocrinology (2009) 201, 37-47

AB Smoking cessation has been demonstrated to reduce the rate of loss of lung function and mortality among patients with mild to moderate chronic obstructive pulmonary disease (COPD). There is a paucity of evidence about the effects of smoking cessation on the risk of COPD exacerbations.
We sought to examine whether smoking status and the duration of abstinence from tobacco smoke is associated with a decreased risk of COPD exacerbations.
We assessed current smoking status and duration of smoking abstinence by self-report. Our primary outcome was either an inpatient or outpatient COPD exacerbation. We used Cox regression to estimate the risk of COPD exacerbation associated with smoking status and duration of smoking cessation.
We performed a cohort study of 23,971 veterans who were current and past smokers and had been seen in one of seven Department of Veterans Affairs (VA) primary care clinics throughout the US.
In comparison to current smokers, ex-smokers had a significantly reduced risk of COPD exacerbation after adjusting for age, comorbidity, markers of COPD severity and socio-economic status (adjusted HR 0.78, 95% CI 0.75-0.87). The magnitude of the reduced risk was dependent on the duration of smoking abstinence (adjusted HR: quit < 1 year, 1.04; 95% CI 0.87-1.26; 1-5 years 0.93, 95% CI 0.79-1.08; 5-10 years 0.84, 95% CI 0.70-1.00; a parts per thousand yen10 years 0.65, 95% CI 0.58-0.74; linear trend < 0.001).
Smoking cessation is associated with a reduced risk of COPD exacerbations, and the described reduction is dependent upon the duration of abstinence.

AB African Americans have higher cancer mortality rates than whites. Understanding the relative contribution of cancer incidence, stage at diagnosis and survival after diagnosis to the racial gap in life expectancy has important implications for directing future health disparity interventions toward cancer prevention, screening and treatment.
We estimated the degree to which higher cancer mortality among African Americans is due to higher incidence rates, later stage at diagnosis or worse survival after diagnosis.
Stochastic model of cancer incidence and survival after diagnosis.
Surveillance and Epidemiology End Result cancer registry and National Health Interview Survey data.
Life expectancy if African Americans had the same cancer incidence, stage and survival after diagnosis as white adults.
African-American men and women live 1.47 and 0.91 fewer years, respectively, than whites as the result of all cancers combined. Among men, racial differences in cancer incidence, stage at diagnosis and survival after diagnosis account for 1.12 (95% CI: 0.52 to 1.36), 0.17 (95% CI: -0.03 to 0.33) and 0.21 (95% CI: 0.05 to 0.34) years of the racial gap in life expectancy, respectively. Among women, incidence, stage and survival after diagnosis account for 0.41 (95% CI: -0.29 to 0.60), 0.26 (95% CI: -0.06 to 0.40) and 0.31 (95% CI: 0.05 to 0.40) years, respectively. Differences in stage had a smaller impact on the life expectancy gap compared with the impact of incidence. Differences in cancer survival after diagnosis had a significant impact for only two cancers-breast (0.14 years; 95% CI: 0.05 to 0.16) and prostate (0.05 years; 95% CI 0.01 to 0.09).
In addition to breast and colorectal cancer screening, national efforts to reduce disparities in life expectancy should also target cancer prevention, perhaps through smoking cessation, and differences in survival after diagnosis among persons with breast and prostate cancer.

TI Medical Record Documentation of Patients' Hearing Loss by Physicians
SO JOURNAL OF GENERAL INTERNAL MEDICINE
LA English
DT Article
DE hearing loss; electronic medical record; patient communication
ID HARD-OF-HEARING
AB Anecdotal evidence suggests that hearing loss, even when sufficient to prevent full access to spoken communication, often is underreported by patients and not documented by physicians. No published studies have investigated this issue quantitatively.
To assess the documentation of hearing loss in comprehensive physician notes in cases where the patients are known to have substantial binaural loss.
Electronic medical record (EMR) notes for 100 consecutive patients with substantial binaural hearing loss were reviewed retrospectively at a large academic medical center. All records reviewed were created within 2 years before the patient's audiometry. Comprehensive physician notes containing the headings "History" and "Physical Exam" were examined for documentation of hearing loss and scored as: no mention of loss; finding of loss; or hearing reported as normal.
Consecutive adult patients with substantial binaural hearing loss by audiometry who also had a comprehensive medical assessment in their electronic medical record created within 2 years before audiometry.
Thirty-six percent of EMRs had no mention of hearing loss, 28% reported some loss, and 36% percent indicated that hearing was normal.
Substantial hearing loss, sufficient to prevent effective communication in the medical setting, often is underdocumented in medical records.

AB Purpose: To evaluate the efficacy and safety of diode laser transscleral cyclophotocoagulation (DLTSC) to control intraocular pressure (IOP) in keratoprosthesis patients with uncontrolled glaucoma.
Patients and Methods: Between 1993 and 2007, 18 eyes of 18 patients underwent DLTSC, either before (n = 3), during (n = I), or after (n = 14) keratoprosthesis surgery. Keratoprosthesis type 1 was used in 72%. All but one of these patients received an Ahmed Glaucoma Valve, either with or after the keratoprosthesis placement. Best-corrected visual acuity, IOP (assessed by digital palpation), number of medications, and complications were recorded preoperatively, at day 7, at 1, 3, and 6 months then every 6 months postoperatively.
Results: Mean follow-tip was 26.6 +/- 19.6 months (mean +/- SD) and mean age was 50.1 +/- 15.6 years. Glaucoma was identified in 1 I eyes before keratoprosthesis surgery and in 7 eyes after. Mean postoperative IOP was significantly reduced at 6, 12, 24, 36, and 48 months after DLTSC. DLTSC was repeated in 6 eyes. At final visit, mean best-corrected visual acuity was not decreased and there were no statistically significant differences in the number of glaucoma medications. Two patients had complications after DLTSC: a conjunctival dehiscence and a fungal endophthalmitis.
Conclusions: DLTSC has beneficial long-term effects in the control of IOP and can be considered in the management of keratoprosthesis patients with refractory glaucoma.

AB Purpose To present the preliminary findings of distal radius fractures (DRF) treated with percutaneous cross-pin fixation and a nonbridging external fixator, the Cross-Pin Fixation (CPX) system.
Methods Thirty-five consecutive patients with 37 DRFs were selected from a series of 51 DRFs for closed reduction, percutaneous pinning, and external fixation with the CPX system. Outcome was determined by studying (1) radiological measurements of radial height, palmar tilt, radial inclination and ulnar variance (UV); (2) grip and pinch strength; (3) wrist active range of motion; and (4) patient outcome instruments-the Patient-Rated Wrist Hand Evaluation and the Disabilities of the Arm, Shoulder, and Hand.
Results We are reporting, on 21 patients, 13 females and 8 males, mean age 54 years (range, 27 to 87 y) with AO type fractures A2, B2, B3, C1, C2, and C3. Follow-up was a minimum of I year (range, 12 to 36 months). Wrist rehabilitation began at a mean of 10 days (range, 4 to 16 d) after surgery. There was no loss of reduction. Final mean grip and lateral pinch strength recovered 86% and 94%, respectively, and active range of motion increased to a minimum of 89% of the noninjured side. Disabilities of the Arm, Shoulder, and Hand showed change in functional status (minimal detectable change at 95% confidence level) at 4 and 12 weeks. The Patient-Rated Wrist Hand Evaluation results reported resumption of usual activities in the early postoperative period. One patient developed type I complex regional pain syndrome, which resolved, and one patient had residual transient mild superficial radial nerve sensitivity. There were no pin track infections, nonunions, or tendon injuries. All patients returned to their prior employment and activities.
Conclusions The CPX system is a minimally invasive technique of closed reduction and internal fixation for displaced reducible extra-articular and nondisplaced and displaced reducible intraarticular fractures of the distal radius, allowing rehabilitation of the wrist and resumption of usual activities while maintaining fracture reduction.

AB Background/Aims: The response rates of HCV infection to interferon therapy vary depending on viral and host factors. We hypothesized that key regulators of the IFN signaling pathway are predictive of treatment outcome.
Methods: We measured the expression of signal transducer and activator of transcription 1 (STAT1) and suppressor of cytokine signaling 3 (SOCS3) in pretreatment liver biopsies. Staining quantitation was compared to treatment outcomes.
Results:Forty-nine patients with HCV and 25 patients with HCV/HIV infection treated with peginterferon/ribavirin were analyzed. Pretreatment hepatic SOCS3 expression was higher in non-responders than responders. Genotype 1 responders had similar levels of SOCS3 as genotype 213 responders. African Americans (AA) had higher hepatic SOCS3 than non-AA. Pretreatment hepatic SOCS3 was the most powerful independent predictor of sustained virologic response (SVR), even more so than genotype by logistic regression analysis. Failure to achieve SVR and AA race were independently associated with high hepatic SOCS3 levels. The hepatic expression of STAT-1 did not differ between responders and non-responders.
Conclusions: Our data indicate that hepatic SOCS3 is a stronger baseline predictor of antiviral response than viral genotype. Poor response to antiviral therapy in AA may be associated with higher hepatic SOCS3 expression. (c) 2009 European Association for the Study of the Liver. Published by Elsevier B.V.

AB BACKGROUND: Slow hospital discharges reduce efficiency and compromise care for patients awaiting a bed. Although efficient discharge is a widely held goal, the natural history of the discharge process has not been well Studied.
OBJECTIVE: To describe the discharge process and identify factors associated with longer and later discharges.
DESIGN: Prospective cohort study.
SETTING: A general medicine ward without house-staff coverage, in a tertiary care hospital (The Johns Hopkins Hospital) in Baltimore, Maryland, from January 1, 2005 to April 30, 2005.
PATIENTS: Two hundred and nine consecutively discharged adult inpatients.
MEASUREMENTS: Discharge time (primary outcome) and discharge duration (secondary outcome).
RESULTS: Median discharge time was 3:09 PM (25th% to 75th%: 1:08 to 5:00 PM) In adjusted analysis, discharge time was associated with ambulance used on discharge (1.5 hours), prescriptions filled prior to discharge (1.4 hours), subspecialty Consult prior to discharge (1.2 hours), and procedure prior to discharge (1.1 hours). Median duration of the discharge process was 7 hours 34 minutes (25th% to 75th%: 4.0 to 22.0 hours). Discharge duration was associated with discharge to a location other than home (28.9 hours), and with need for consultation (14.8 hours) or a procedure (13.4 hours) prior to discharge (all P values < 0.05).
CONCLUSIONS: Discharge time and duration have wide variability Longer and later discharges were associated with procedures and Consults. Successful efforts to decrease time of discharge will require broad institutional effort to improve delivery of interdepartmental services. Journal of Hospital Medicine 2009;4:226-233.

AB Objective To evaluate the hypertensive effects of etoricoxib and diclofenac relative to baseline hypertension risk factors in arthritis patients.
Methods Multivariate analysis of data from the Multinational Etoricoxib and Diclofenac Arthritis Long-term (MEDAL) study (n = 23 504). We evaluated risk factors for change in systolic blood pressure (BP) (SBP) and diastolic BP (DBP) at 4 months versus baseline; exceeding predefined limits of change (PLoC) in BID anytime during the study; and the effect of concomitant anti hypertensive class on SBP and exceeding SBP PLoC.
Results Increased SBP was most highly associated with history of hypertension (+3.04 mmHg; P<0.0001), as were increased DBP (+1.28 mmHg; P<0.0001), and exceeding DBP PLoC [odds ratio (OR) = 1.83; P<0.0001]. Exceeding SBP PLoC (OR = 1.50; P<0.0001) was most highly associated with age at least 65 years. Etoricoxib (vs. diclofenac) was also significantly associated with increased SBP (P<0.0001), DPB (P<0.0001 to P = 0.0015), and exceeding SBP PLoC (P<0.0001 to P=0.002). Compared with no antihypertensive medication, background calcium channel blockers (CCB) were associated with a small, nonsignificant decrease in SBP (-0.60 mmHg) and no increased odds of exceeding SBP PLoC [OR = 1.00 (95% Cl 0.71, 1.42)]. All other antihypertensive classes were associated with either no change or numerically or statistically significantly increased SBP and increased odds of exceeding PLoC.
Conclusion History of hypertension and age at least 65 years were most strongly associated with increased BID. Treatment with etoricoxib vs. diclofenac was also a significant factor for increased BID. CCBs appear to maintain antihypertensive effects with concurrent NSAID therapy better than other examined anti hypertensive drug classes.

AB QT interval prolongation is associated with increased risk of sudden cardiac death at the population level. As 30-40% of the QT-interval variability is heritable, we tested the association of common LQTS and NOS1AP gene variants with QT interval in a Finnish population-based sample.
We genotyped 12 common LQTS and NOS1AP genetic variants in Health 2000, an epidemiological sample of 5043 Finnish individuals, using Sequenom MALDI-TOF mass spectrometry. ECG parameters were measured from digital 12-lead ECGs and QT intervals were adjusted for age, gender and heart rate with a nomogram (Nc) method derived from the present study population.
The KCNE1 D85N minor allele (frequency 1.4%) was associated with a 10.5 ms (SE 1.6) or 0.57 SD prolongation of the adjusted QT(Nc) interval (P = 3.6 x 10(-11)) in gender-pooled analysis. In agreement with previous studies, we replicated the association with QT(Nc) interval with minor alleles of KCNH2 intronic SNP rs3807375 [1.6 ms (SE 0.4) or 0.08 SD, P = 4.7 x 10(-5)], KCNH2 K897T [-2.6 ms (SE 0.5) or -0.14 SD, P = 2.1 x 10(-7)] and NOSA1P variants including rs2880058 [4.0 ms (SE 0.4) or 0.22 SD, P = 3.2 x 10(-24)] under additive models.
We demonstrate that each additional copy of the KCNE1 D85N minor allele is associated with a considerable 10.5 ms prolongation of the age-, gender- and heart rate-adjusted QT interval and could thus modulate repolarization-related arrhythmia susceptibility at the population level. In addition, we robustly confirm the previous findings that three independent KCNH2 and NOSA1P variants are associated with adjusted QT interval.

AB Management of large bore arterial access sites often represents a challenge during interventional procedures, and usually requires prolonged manual compression, though suture-mediated closure techniques have been described. We report our experience in using the Mynx vascular closure device to close a 14 French femoral arteriotomy in two patients undergoing percutaneous balloon aortic valvuloplasty.

AB UVB irradiation potently induces cytokines in the skin, including IL-1 alpha and tumor necrosis factor-alpha (TNF-alpha). The mechanism for TNF-alpha induction in UVB-irradiated keratinocytes is not clear. In this study, we explored the effects of UVB and cytokines, alone or in combination in human keratinocytes. Keratinocytes were sham-or UVB-irradiated with 30 mJ cm(-2), and then incubated in the absence or presence of IFN-alpha 2b, TNF-alpha, or IL-1 alpha. UVB and IL-1 alpha treatment synergistically enhanced TNF-alpha secretion and mRNA levels in human keratinocytes, similar to the findings reported previously in human fibroblasts. Exogenous recombinant TNF-alpha up-regulates its own mRNA level. However, addition of IFN-alpha 2b did not show any additive effect on TNF-alpha mRNA induction. To understand the regulation of TNF-alpha mRNA by UVB, with or without IL-1 alpha, we examined the transcription rate and half-life of TNF-alpha mRNA. Treatment of keratinocytes with IL-1 alpha or UVB alone increased TNF-alpha gene transcription 4- to 5-fold over sham treatment, and TNF-alpha gene transcription increased 11-fold in cells treated with UVB plus IL-1 alpha over sham. UVB with IL-1 alpha did not enhance the half-life of TNF-alpha mRNA over that seen with UVB alone. In conclusion, TNF-alpha expression in primary keratinocytes is upregulated transcriptionally by UVB and IL-1 alpha.

AB Agent-based modeling (ABM) is an in silico technique that is being used in a variety of research areas such as in social sciences, economics and increasingly in biomedicine as an interdisciplinary tool to study the dynamics of complex systems. Here, we describe its applicability to integrative tumor biology research by introducing a multi-scale tumor modeling platform that understands brain cancer as a complex dynamic biosystem. We summarize significant findings of this work, and discuss both challenges and future directions for ABM in the field of cancer research.

CHROMOSOME 15Q13-14; PARTIAL DUPLICATION
AB Background: Segmental duplications at breakpoints (BP4-BP5) of chromosome 15q13.2q13.3 mediate a recurrent genomic imbalance syndrome associated with mental retardation, epilepsy, and/or electroencephalogram (EEG) abnormalities.
Patients: DNA samples from 1445 unrelated patients submitted consecutively for clinical array comparative genomic hybridisation (CGH) testing at Children's Hospital Boston and DNA samples from 1441 individuals with autism from 751 families in the Autism Genetic Resource Exchange (AGRE) repository.
Results: We report the clinical features of five patients with a BP4-BP5 deletion, three with a BP4-BP5 duplication, and two with an overlapping but smaller duplication identified by whole genome high resolution oligonucleotide array CGH. These BP4-BP5 deletion cases exhibit minor dysmorphic features, significant expressive language deficits, and a spectrum of neuropsychiatric impairments that include autism spectrum disorder, attention deficit hyperactivity disorder, anxiety disorder, and mood disorder. Cognitive impairment varied from moderate mental retardation to normal IQ with learning disability. BP4-BP5 covers similar to 1.5 Mb (chr15: 28.719-30.298 Mb) and includes six reference genes and 1 miRNA gene, while the smaller duplications cover similar to 500 kb (chr15: 28.902-29.404 Mb) and contain three reference genes and one miRNA gene. The BP4-BP5 deletion and duplication events span CHRNA7, a candidate gene for seizures. However, none of these individuals reported here have epilepsy, although two have an abnormal EEG.
Conclusions: The phenotype of chromosome 15q13.2q13.3 BP4-BP5 microdeletion/duplication syndrome may include features of autism spectrum disorder, a variety of neuropsychiatric disorders, and cognitive impairment. Recognition of this broader phenotype has implications for clinical diagnostic testing and efforts to understand the underlying aetiology of this syndrome.

TI Older Patients' Enthusiasm to Use Electronic Mail to Communicate With
Their Physicians: Cross-Sectional Survey
SO JOURNAL OF MEDICAL INTERNET RESEARCH
LA English
DT Article
DE Electronic mail; doctor-patient communication; Internet; doctor-patient
relationship
ID MEDICAL ENCOUNTER; HEALTH-CARE; EMAIL; INTERNET; DIVIDE; ACCESS
AB Background: Recent evidence indicates increased access to and use of Internet and non-healthcare-related email by older patients. Because email adoption could potentially reduce some of the disparities faced by this age group, there is a need to understand factors determining older patients' enthusiasm to use email to communicate with their physicians. Electronic mail (email) represents a means of communication that, coupled with face-to-face communication, could enhance quality of care for older patients.
Objective: Testa model to determine factors associated with older patients' enthusiasm to use email to communicate with their physicians.
Methods: We conducted a secondary data analysis of survey data collected in 2003 for two large, longitudinal, randomized controlled trials. Logistic-regression models were used to model the dichotomous outcome of patient enthusiasm for using email to communicate with their physicians. Explanatory variables included demographic characteristics, health status, use of email with people other than their physician, characteristics of the physician-patient relationship, and physician enthusiasm to use email with patients.
Results: Participants included a pooled sample of 4059 patients over 65 years of age and their respective physicians (n = 181) from community-based practices in Southern California. Although only 52 (1.3%) patient respondents reported that they communicated with their physician by email, about half (49.3%) expressed enthusiasm about the possibility of using it. Odds of being enthusiastic decreased with increased age (by 0.97 for each year over 66) but were significantly higher in African Americans (OR = 2.1, CI = 1.42 - 3.06), Hispanics (OR = 1.6, CI = 1.26 - 2.14) and men (OR = 1.3, CI = 1.1 - 1.5). A perception of better communication skills of their physician, lower quality of interaction with physician in traditional face-to-face encounters, and physician enthusiasm to use email with patients were significantly associated with an enthusiasm to use email. Patients who did not use email at all were less enthusiastic compared to those who used email for other reasons. Half of the physician respondents were not enthusiastic about communicating with patients using email.
Conclusions: Despite perceived barriers such as limited access to the Internet, older patients seem to want to use email to communicate with their physicians.

AB Influenza viruses cause significant morbidity and mortality in adults each winter. At the same time, other respiratory viruses circulate and cause respiratory illness with influenza-like symptoms. Human respiratory syncytial virus (HRSV), human parainfluenza viruses (HPIV) and human metapneumovirus have all been associated with morbidity and mortality in adults, including nosocomial infections. This study evaluated 154 respiratory specimens collected from adults with influenza-like/acute respiratory illness (ILI) seen at the Edward Hines Jr VA Hospital, Hines, IL, USA, during two successive winters, 1998-1999 and 1999-2000. The samples were tested for ten viruses in two nested multiplex RT-PCRs. One to three respiratory viruses were detected in 68% of the samples. As expected, influenza A virus (FLU-A) infections were most common (50% of the samples), followed by HRSV-A (16%). Surprisingly, HPIV-4 infections (5.8%) were the third most prevalent. Mixed infections were also relatively common (11%). When present, HPIV infections were approximately three times more likely to be included in a mixed infection than FLU-A or HRSV. Mixed infections and HPIV-4 are likely to be missed using rapid diagnostic tests. This study confirms that ILI in adults and the elderly can be caused by HRSV and HPIVs, including HPIV-4, which co-circulate with FLU-A.

AB The SLC26 gene family encodes anion transporters with diverse functional attributes: (a) anion exchanger, (b) anion sensor, and (c) anion conductance (likely channel). We have cloned and studied Slc26a9, a paralogue expressed mostly in lung and stomach. Immunohistochemistry shows that Slc26a9 is present at apical and intracellular membranes of lung and stomach epithelia. Using expression in Xenopus laevis oocytes and ion-sensitive microelectrodes, we discovered that Slc26a9 has a novel function not found in any other Slc26 proteins: cation coupling. Intracellular pH and voltage measurements show that Slc26a9 is a nCl(-)-HCO (3) (-) exchanger, suggesting roles in gastric HCl secretion or pulmonary HCO (3) (-) secretion; Na+ electrodes and uptakes reveal that Slc26a9 has a cation dependence. Single-channel measurements indicate that Slc26a9 displays discrete open and closed states. These experiments show that Slc26a9 has three discrete physiological modes: nCl(-)-HCO (3) (-) exchanger, Cl- channel, and Na+-anion cotransporter. Thus, the Slc26a9 transporter channel is uniquely suited for dynamic and tissue-specific physiology or regulation in epithelial tissues.

AB Impulsivity among individuals with eating disorders (EDs) is associated with severe comorbidities and poor treatment Outcome. However, research investigating the construct of impulsivity in EDs is limited. The objectives of the present study were to characterize multiple dimensions of impulsivity in adolescents with EDs; determine if differences in impulsivity were associated with ED diagnosis and/or broader personality traits; and explore the relationship between impulsivity and etiologically significant variables. Experienced clinicians from a practice-research network provided data on ED symptoms, impulsive characteristics, personality pathology, The Diagnostic and Statistical Manual of Mental Disorders comorbidity, and family and developmental history for 120 adolescent patients with EDs. Three distinct types of impulsivity were identified: general, acting out, and aggressive/destructive. The impulsivity types showed specific relationships to ED diagnosis, broader personality factors, individual histories of adverse (traumatic) events, and family histories of externalizing disorders, supporting the importance of taking, assessing, and addressing impulsivity in ED research and treatment.

AB Recent clinical trial results suggest that anti-angiogenic therapy may be effective against recurrent malignant glioma. Though these treatments prolong progression-free survival, the extent to which they prolong overall survival is unknown. We pooled data from 34 patients treated at a single institution on phase II clinical trials of bevacizumab and cediranib, and we compared these data to 18 patients treated on clinical trials of cytotoxic chemotherapies. In univariate and multivariate analyses, treatment group was a significant predictor of progression-free but not overall survival. Median progression-free survival was 8 vs. 22 weeks in patients treated with cytotoxic as compared to anti-angiogenic therapy (P = 0.01). Median overall survival was nearly identical in the two groups (39 vs. 37 weeks). The results of this exploratory analysis suggest that anti-angiogenic therapy may fail to prolong overall survival in patients with recurrent malignant glioma. If this conclusion proves correct, progression-free survival may be an inappropriate endpoint for phase II trials of anti-angiogenic therapies.

DE Dural arteriovenous fistula; AVM; parkinsonism; reversible
ID DEMENTIA
AB The most common causes of parkinsonism are degenerative and irreversible. Structural causes of reversible parkinsonism are exceptionally rare, but have been reported in association with deep cerebral venous thrombosis and dural arteriovenous fistula (DAVF). We now report a case of parkinsonian syndrome reversed by treatment of a dural arteriovenous malformation.
Case report with retrospective review of relevant clinical, imaging, and treatment data.
A 79-year-old man presented with complaints of a slowly progressive parkinsonian syndrome and tinnitus. Brain magnetic resonance imaging (MRI) showed numerous serpiginous flow voids highly suggestive of a vascular malformation. Cerebral angiography revealed a Cognard grade IIa + b left transverse sinus DAVF. The patient underwent combined endovascular and surgical treatment in three stages over a week's time, with total obliteration of the DAVF and complete normalization of his symptoms and neurological examination.
Although rare, DAVF should always be considered as a potential cause of progressive parkinsonism. This diagnosis is of great importance because of its potential reversibility.

AB Leukoencephalopathy with cerebral calcifications and cysts (LCC) was first reported in children who developed cognitive decline and variable extrapyramidal, cerebellar, and pyramidal signs.. with or without seizures. Leukoencephalopathy with cerebral calcifications and cysts is characterized by progressive formation of brain cysts that can generate a mass effect simulating a neoplasm. Retinal changes that overlap with Coats disease, a microangiopathy with retinal telangiectasias and exudates, may also Occur. We and others have reported LCC cases in adults. Neuroimaging shows diffuse leukoencephalopathy, multifocal calcifications especially of deep gray and white matter, multifocal enhancement, and variably sized cysts that may require surgical decompression. Biopsies adjacent to cysts have shown angiomatous and/or severely hyalinized blood vessels surrounded by myelin loss and gliosis, calcifications, and Rosenthal fibers. We report 2 additional adult-onset cases of LCC. Case I is a 40-year-old mail who developed neurological symptoms and cirrhosis and died of acute gastrointestinal bleeding, fie had numerous retinal microinfarcts at autopsy. Case 2 is a 55-year-old woman who was found by chance to have LCC; one and a half years later, her Course remains benign. These cases expand the spectrum Of adult-onset LCC, the etiology of which is unknown.

First published February 4, 2009; doi:10.1152/jn.91081.2008. Electric stimulation of the retina reliably elicits light percepts in patients blinded by outer retinal diseases. However, individual percepts are highly variable and do not readily assemble into more complex visual images. As a result, the quality of visual information conveyed to patients has been quite limited. To develop more effective stimulation methods that will lead to improved psychophysical outcomes, we are studying how retinal neurons respond to electric stimulation. The situation in the retina is analogous to other neural prosthetic applications in which a better understanding of the underlying neural response may lead to improved clinical outcomes. Here, we determined which element in retinal ganglion cells has the lowest threshold for initiating action potentials. Previous studies suggest multiple possibilities, although all were within the soma/proximal axon region. To determine the actual site, we measured thresholds in a dense two-dimensional grid around the soma/proximal axon region of rabbit ganglion cells in the flat mount preparation. In directionally selective (DS) ganglion cells, the lowest thresholds were found along a small section of the axon, about 40 mu m from the soma. Immunochemical staining revealed a dense band of voltage-gated sodium channels centered at the same location, suggesting that thresholds are lowest when the stimulating electrode is closest to the sodium-channel band. The size and location of the low-threshold region was consistent within DS cells, but varied for other ganglion cell types. Analogously, the length and location of sodium channel bands also varied by cell type. Consistent with the differences in band properties, we found that the absolute (lowest) thresholds were also different for different cell types. Taken together, our results suggest that the sodium-channel band is the site that is most responsive to electric stimulation and that differences in the bands underlie the threshold differences we observed.

TI JNK-Induced MCP-1 Production in Spinal Cord Astrocytes Contributes to

AB Our previous study showed that activation of c-jun-N-terminal kinase (JNK) in spinal astrocytes plays an important role in neuropathic pain sensitization. We further investigated how JNK regulates neuropathic pain. In cultured astrocytes, tumor necrosis factor alpha(TNF-alpha) transiently activated JNK via TNF receptor-1. Cytokine array indicated that the chemokine CCL2/MCP-1 (monocyte chemoattractant protein-1) was strongly induced by the TNF-alpha/JNK pathway. MCP-1 upregulation by TNF-alpha was dose dependently inhibited by the JNK inhibitors SP600125 (anthra[1,9-cd] pyrazol-6(2H)-one) and D-JNKI-1. Spinal injection of TNF-alpha produced JNK-dependent pain hypersensitivity and MCP-1 upregulation in the spinal cord. Furthermore, spinal nerve ligation (SNL) induced persistent neuropathic pain and MCP-1 upregulation in the spinal cord, and both were suppressed by D-JNKI-1. Remarkably, MCP-1 was primarily induced in spinal cord astrocytes after SNL. Spinal administration of MCP-1 neutralizing antibody attenuated neuropathic pain. Conversely, spinal application of MCP-1 induced heat hyperalgesia and phosphorylation of extracellular signal-regulated kinase in superficial spinal cord dorsal horn neurons, indicative of central sensitization (hyperactivity of dorsal horn neurons). Patch-clamp recordings in lamina II neurons of isolated spinal cord slices showed that MCP-1 not only enhanced spontaneous EPSCs but also potentiated NMDA- and AMPA-induced currents. Finally, the MCP-1 receptor CCR2 was expressed in neurons and some non-neuronal cells in the spinal cord. Together, we have revealed a previously unknown mechanism of MCP-1 induction and action. MCP-1 induction in astrocytes after JNK activation contributes to central sensitization and neuropathic pain facilitation by enhancing excitatory synaptic transmission. Inhibition of the JNK/MCP-1 pathway may provide a new therapy for neuropathic pain management.

AB The transcriptional corepressor SnoN is a critical regulator of axonal morphogenesis, but how SnoN drives axonal growth is unknown. Here, we report that gene-profiling analyses in cerebellar granule neurons reveal that the large majority of genes altered upon SnoN knockdown are surprisingly downregulated, suggesting that SnoN may activate transcription in neurons. Accordingly, we find that the transcriptional coactivator p300 interacts with SnoN, and p300 plays a critical role in SnoN-induced axon growth. We also identify the gene encoding the signaling scaffold protein Ccd1 as a critical target of SnoN in neurons. Ccd1 localizes to the actin cytoskeleton, is enriched at axon terminals in neurons, and activates the axon growth-promoting kinase JNK (c-Jun N-terminal protein kinase). Knockdown of Ccd1 in neurons reduces axonal length and suppresses the ability of SnoN to promote axonal growth. Importantly, Ccd1 knockdown in rat pups profoundly impairs the formation of granule neuron parallel fiber axons in the rat cerebellar cortex in vivo. These findings define a novel SnoN-Ccd1 link that promotes axonal growth in the mammalian brain, with important implications for axonal development and regeneration.

AB Clinical and radiographic evidence of subarachnoid hemorrhage (SAH)-related vasospasm is rare in children and has not been reported in infants. In this report the authors present the case of a 22-month-old child who developed clinically symptomatic, radiographically identifiable vasospasm after traumatic SAH. To the authors' knowledge, this is the first report of vasospasm associated with SAH in a child this young. This 22-month-old boy fell and had a dense SAH. He had a history of surgically corrected craniosynostosis and nonsymptomatic ventriculomegaly. The boy was evaluated for occult vascular lesions using imaging; none were found and normal vessel caliber was noted. Ten days later, the child developed left-sided weakness and a right middle cerebral artery infarct was identified. Evaluation disclosed significant intracranial vasospasm. This diagnosis was supported by findings on CT angiography, transcranial Doppler ultrasonography, MR imaging, and conventional angiography. The child was treated using intraarterial verapamil with a good result, as well as with conventional intensive care measures to reduce vasospasm. This report documents the first known case of intracranial vasospasm with stroke after SAH in a patient under the age of 2 years. This finding is important because it demonstrates that the entity of SAH-associated vasospasni can affect the very young, widening the spectrum of ages susceptible to this condition. This case is also important because it demonstrates that even very young children can respond to conventional therapeutic interventions such as intraarterial verapamil. Thus,, clinicians need to be alert to the possibility of vasospasm as a potential diagnosis when evaluating Young children with SAH. (DOI: 10.3171/2008.12.PEDS08206)

AB Chronic pain patients who are treated with opioid therapy represent a significant challenge to medical professionals. When. pain recurs in the face of a, previously effective opioid regimen, treatment options include (lose escalation., opioid rotation, drug holidays, and the addition Of adjuvants. Some experts advocate the use of N-methyl-D-aspartate receptor (NMDA-R) antagonists to combat tolerance. Recently the use of an, intravenous (i.v.) ketamine infusion to Predict the response to a dextromethorphan (DX) treatment trial has been described. In this study, 56 opioid-exposed patients with recurrent pain were treated with a low-dose (0.1 mg/kg) i.v. ketamine test followed by a DX treatment course. Using previously designated cutoff values for a positive response to ketamine (67% or more pain relief) and DX (50% or more pain relief), the sensitivity, specificity, positive predictive value, and negative Predictive value for an i.v. ketamine infusion to predict subsequent response to DX treatment were 72%, 68%, 52%, and 85%, respectively. The observed agreement between. an.,algesic responses was 78%, indicating a highly significant correlation (r = 0.54, P = 0.0001). Subgroup classification in the response to either ketamine or DX classification revealed no significant differences treatment, based on pain classification (i.e., nociceptive, neuropathic, or mixed) or placebo response. In contrast, a weaker correlation between ketamine and DX response was found in subjects requiring high-dose rather than low-dose opioid therapy. A significant correlation also was noted between. the development of side effects for the two NMDA-R antagonists. Based on These results, we conclude that an i.v. ketamine test may be a valuable toot in predicting subsequent response to DX treatment in opioid-exposed patients. with Persistent pain, J Pain Symptom Manage 2009;37:698-708.

TI Safety of Frequent Venous Blood Sampling in a Pediatric Research
Population
SO JOURNAL OF PEDIATRICS
LA English
DT Article
ID ERYTHROPOIESIS
AB Objective To monitor hematological indices in otherwise healthy children with central precocious puberty who underwent frequent venous sampling as part of a longitudinal clinical research study.
Study design Thirty-four female subjects underwent frequent venous sampling (every 10-20 minutes for 8-16 hours) every 6 months for >= 3 years during and after their treatment with a gonadotropin-releasing hormone analogue. Hemoglobin (Hgb), mean corpuscular volume, and ferritin levels were measured before and after each phlebotomy session.
Results At baseline, the average Hgb level was 12.5 +/- 0.7 g/L. At the conclusion of the first sampling session, the Hgb level fell 1.2 +/- 0.1 g/L, remaining within the reference range for age. At the 3-month follow-up, there was complete recovery of Hgb (12.6 +/- 0.2 g/L). Longitudinal evaluation every 6 months for as long as 3 years showed no significant differences in Hgb, mean corpuscular volume, or ferritin levels from baseline. No clinically significant adverse effects attributable to phlebotomy were reported.
Conclusion When appropriate safety guidelines were followed, both acute and long-term frequent venous sampling in a pediatric population was safe. Guidelines include monitoring of hematological indices, phlebotomy volume < 10 mL/kg/24 hours, and iron replacement. (J Pediatr 2009;154:578-81)

AB G alpha(s) and extra-large G alpha(s) (XL alpha(s)) can both transduce receptor activation into intracellular cAMP generation. It is unknown, however, whether these two GNAS-locus products display distinct properties with respect to receptor coupling. Here, we show that XL alpha(s) couples to the beta 2-adrenoceptor more efficiently than G alpha(s). In transfected human embryonic kidney 293 cells and mouse embryonic fibroblasts null for both G alpha(s) and XL alpha(s) (2B2 cells), basal cAMP accumulation mediated by XL alpha(s) was higher than that mediated by G alpha(s). Inverse agonist treatment reduced G alpha(s)-mediated basal activity, whereas its effect was markedly blunted on XL alpha(s)-mediated basal activity. Rank order of ligand efficacies regarding cAMP accumulation was the same when the receptor was coupled to XL alpha(s) or G alpha(s). However, ligand-induced and XL alpha(s)-mediated cAMP generation was higher than that mediated by G alpha(s). The relatively high efficiency of XL alpha(s)-mediated cAMP generation was conditional, disappearing with increased level of receptor expression or increased efficacy of ligand. Full-agonist responses in XL alpha(s)- and G alpha(s)-expressing cells were comparable even at low receptor levels, whereas partial agonist responses became comparable only when the receptor expression was increased (>3 pmol/mg). Radioligand binding studies showed that the high-affinity component in agonist binding to beta 2-adrenoceptor was more pronounced in cells expressing XL alpha(s) than those expressing G alpha(s). We discuss these findings in the framework of current receptor-G protein activation models and offer an extended ternary complex model that can fully explain our observations.

AB Buprenorphine is an effective long-term opioid agonist treatment. As the only pharmacological treatment for opioid dependence readily available in office-based settings, buprenorphine may facilitate a historic shift in addiction treatment from treatment facilities to general medical practices. Although many patients have benefited from the availability of buprenorphine in the United States, almost half of current prescribers are addiction specialists suggesting that buprenorphine treatment has not yet fully penetrated general practice settings. We examined factors affecting willingness to offer buprenorphine treatment among physicians with different levels of prescribing experience. Based on their prescribing practices, physicians were classified as experienced, novice, or as a nonprescriber and asked to assess the extent to which a list of factors impacted their prescription of buprenorphine. Several factors affected willingness to prescribe buprenorphine for all physicians: staff training; access to counseling and alternate treatment; visit tune; buprenorphine availability; and pain medications concerns. Compared with other physicians, experienced prescribers were less concerned about induction logistics and access to expert consultation, clinical guidelines, and mental health services. They were more concerned with reimbursement. These data provide important insight into physician concerns about buprenorphine and have implications for practice, education, and policy change that may effectively support widespread adoption of buprenorphine.

AB This study examined the patient- and facility-level associations between the continuity of care performance measure adopted by the Department of Veterans Affairs (VA) and improvements in self-administered Addiction Severity Index (ASI) composites and other indicators of problematic substance use. Up to 50 patients from each of a nationally representative sample of 109 VA substance use disorder (SUD) treatment programs at 73 VA facilities were assessed at intake and posttreatment. The continuity of care performance measure specifies that patients should receive at least two SUD outpatient visits in each of the three consecutive 30-day periods after they qualify as new SUD patients. In analyses adjusting for baseline characteristics, meeting the continuity of care performance measure was not associated with patient-level improvements in the ASI alcohol or drug composites, days of alcohol intoxication, or days of substance-related problems. Facility-level rates of continuity of care were negatively associated with improvements in ASI alcohol and drug composites. The continuity of care performance measure derived from prior patient-level evidence did not discriminate facility-level performance as predicted. Translating research into process-of-care quality measures requires postconstruction validation. Published by Elsevier Inc.

AB The purpose of this article is to evaluate the contributions of diabetic complications to depression beyond the contributions of demographic characteristics in patients with type 2 diabetes. Further, this article evaluates the contributions of diabetic complications, depression, and quality of life to A1C (also know as HbA1c) beyond the contributions of demographic characteristics in individuals with type 2 diabetes.
A cross-sectional survey of 55 individuals with type 2 diabetes attending an inner city diabetes specialty clinic. Patients completed the Beck Depression Inventory - II, the Inventory of Depressive Symptomatology Self-Report, the Medical Outcome Study Short Form-36, and a demographic questionnaire. A1C and diabetes-related comorbidities were obtained from the patients' medical records.
Being younger and female were associated with depression in individuals with type 2 diabetes. After controlling for age and gender, neuropathy tended to add to the prediction of depression; other comorbidities did not. Being black was associated with poor diabetic control (A1C > 7). After controlling for race, neuropathy and retinopathy predicted poor diabetes control and depression tended to predict poor diabetes control.
Given the high prevalence of depression, the relationship of depression with poor diabetic self-care and medication adherence, and the increased cost of treatment for patients with depression among individuals with type 2 diabetes, assessment of depression is crucial. Further research is needed to establish effective treatment of depression and its effect on glycemic control in patients with type 2 diabetes.

AB Acromioclavicular joint injuries represent nearly half of all athletic shoulder injuries, often resulting from a fall onto the tip of the shoulder with the arm in adduction. Stability of this joint depends on the integrity of the acromioclavicular ligaments and capsule as well as the coracoclavicular ligaments and the trapezius and deltoid muscles. Along with clinical examination for tenderness and instability, radiographic examination is critical in the evaluation of acromioclavicular joint injuries. Nonsurgical treatment is indicated for type I and II injuries; surgery is almost always recommended for type IV, V, and VI injuries. Management of type III injuries remains controversial, with nonsurgical treatment favored in most instances and reconstruction of the acromioclavicular joint reserved for symptomatic instability. Recommended techniques for stabilization in cases of acute and late symptomatic instability include screw fixation of the coracoid process to the clavicle, coracoacromial ligament transfer, and coracoclavicular ligament reconstruction. Biomechanical studies have demonstrated that anatomic acromioclavicular joint reconstruction is the most effective treatment for persistent instability.

AB Microgel particles capable of bulk degradation have been synthesized from a solution of diacrylated triblock copolymer composed of poly(ethylene glycol) and poly(lactic acid) in a microfluidic device using stop-flow lithography (SFL). It has been previously demonstrated that SFL can be used to fabricate particles with precise control over particle size and shape. Here, we have fabricated hydrogel particles of varying size and shape and examined their mass-loss and swelling behavior histologically and mechanically. We report that these features, as well as degradation behavior of the hydrogel particles may be tailored with SFL. By reducing the applied UV dose during fabrication, hydrogel particles can be made to exhibit a distinct deviation from the classical erosion profiles of bulk-degrading hydrogels. At higher UV doses, a saturation in cross-linking density occurs and bulk-degrading behavior is observed. Finally, we synthesized multifunctional composite particles, providing unique features not found in homogeneous hydrogels.

AB Objective: Evidence from observational studies has suggested that carbohydrate quality rather than absolute intake is associated with greater risk of chronic diseases. The aim of this study was to examine the relationship between carbohydrate intake and dietary glycemic index and several cardiovascular disease risk factors.
Methods: We examined cross-sectional associations between total carbohydrate and dietary glycemic index (GI) intakes and several cardiovascular disease risk factors (CVD) in a sample of 2,941 Framingham Offspring Participants. CVD risk factors included waist, blood pressure, lipids, fasting insulin, fasting glucose, and the insulin sensitivity index (ISI(0.120)). Dietary intake was assessed by a food frequency questionnaire (FFQ) and categorized by quintiles of dietary intake.
Results: After adjustment for potential confounding factors, dietary GI was positively associated with fasting triglycerides (mean: 115mg/dL in the lowest and 127 mg/dL in the highest quintile of intake; P for trend < 0.001), fasting insulin (26.8 and 28.9 mu u/mL, respectively, P for trend < 0.0001), and inversely associated with HDL cholesterol (49 and 47 mg/dL, respectively, P for trend 0.003) and ISI(0.120) (26.8 and 25.1, P for trend <0.001). There was no significant relationship between dietary GI and waist circumference, total cholesterol, LDL cholesterol and fasting glucose. Intakes of total carbohydrate were inversely associated with waist circumference and HDL cholesterol, and positively associated with fasting triglycerides.
Conclusion: These cross-sectional findings support the hypothesis that a high GI diet unfavorably affects CVD risk factors and therefore, substitution of high with low GI dietary carbohydrates may have reduce the risk of CVD.

ID MANAGEMENT
AB To determine the prevalence of constipation symptoms and the effects of a brief toileting assistance trial on constipation in a sample of fecally incontinent nursing home (NH) residents.
Observational study.
Five NHs.
One hundred eleven fecally incontinent NH residents.
Research staff measured bowel movement frequency every 2 hours for 10 days. The following week, residents were offered toileting assistance every 2 hours for 2 days to determine resident straining, time required for a bowel movement, and resident perceptions of feeling empty after a bowel movement. Constipation data were abstracted from the medical record.
The frequency of bowel movements during usual NH care was low (mean=0.32 per person per day), and most episodes were incontinent. The frequency of bowel movements increased significantly, to 0.82 per person per day, and most episodes were continent during the 2 days that research staff provided toileting assistance. Eleven percent of residents showed evidence of straining, and 21% of the time after a continent bowel movement, residents reported not feeling empty. Five percent of participants had medical record or Minimum Data Set documentation indicative of constipation symptoms.
Low rates of bowel movements during the day that are potentially indicative of constipation were immediately improved during a 2-day trial of toileting assistance in approximately 68% of the residents, although other symptoms of constipation remained in a subset of residents who increased toileting frequency.

AB To examine "real world" treatments for patients with mild cognitive impairment (MCI).
Cross-sectional.
California Department of Public Health Alzheimer's Disease (AD) Research Centers of California.
Five hundred seventy-eight patients diagnosed with MCI.
All patients underwent comprehensive neurological and neuropsychological evaluations. Logistic regression models were used to determine patient characteristics associated with use of anti-AD medications, statins, antioxidants, and folic acid.
One hundred sixty-six patients (28.7%) were taking anti-AD medications; use was associated with greater functional impairment, higher education, MCI subtype, and older age (P <.05 for all). Two hundred fifty-two patients (43.6%) were taking statins; use was associated with diabetes mellitus, hypertension, myocardial infarct, male sex, and MCI subtype (P <.05 for all). One hundred fifteen patients (19.9%) were taking antioxidants; use was associated with higher education and diabetes mellitus and varied according to site (P <.05 for all). Thirty-seven patients (6.4%) were taking folic acid; use was associated with nonwhite race, male sex, and greater functional impairment (P <.05 for all).
This study suggests that patients with MCI are frequently being treated with "off label" cholinesterase inhibitors and memantine, as well as other possible cognition-enhancing drugs. Further investigation of the effect of treatment patterns on the clinical course of MCI is needed.

ATTACHMENT DISORGANIZATION; IMPULSIVE AGGRESSION
AB As advances in neuroscience have furthered our understanding of the role of brain circuitry, genetics, stress, and neuromodulators in the regulation of normal behavior and in the pathogenesis of psychopathology, an increasing appreciation of the role of neurobiology in individual differences in personality and their pathology in personality disorders has emerged. Individual differences in the regulation and organization of cognitive processes, affective reactivity, impulse/action patterns, and anxiety may in the extreme provide susceptibilities to personality disorders such as borderline and schizotypal personality disorder. A low threshold for impulsive aggression, as observed in borderline and antisocial personality disorders, may be related to excessive amygdala reactivity, reduced prefrontal inhibition, and diminished serotonergic facilitation of prefrontal controls. Affective instability may be mediated by excessive limbic reactivity in gabaminergic/glutamatergic/cholinergic circuits, resulting in an increased sensitivity or reactivity to environmental emotional stimuli as in borderline personality disorder and other cluster B personality disorders. Disturbances in cognitive organization and information processing may contribute to the detachment, desynchrony with the environment, and cognitive/perceptional distortions of cluster A or schizophrenia spectrum personality disorders. A low threshold for anxiety may contribute to the avoidant, dependent, and compulsive behaviors observed in cluster C personality disorders. These alterations in critical regulatory domains will influence how representations of self and others are internalized. Aspects of neurobiological functioning themselves become cognized through the medium of figurative language into an ongoing narrative of the self, one that can be transformed through the analytic process, allowing for the modulation of genetic/biological thresholds.

Ventricular to Right Atrial Shunt (Gerbode Defect)

LA English
DT Article
DE Aortic valve replacement; Gerbode defect; Three-dimensional
echocardiography
AB A 60-year-old man was readmitted 1 year after bioprosthetic aortic valve replacement for recurrent endocarditis. Transthoracic 2-dimensional color Doppler revealed a novel finding of a left-to-right shunt from the left ventricular outflow tract to the right atrium immediately superior to the septal leaflet of the tricuspid valve consistent with an acquired Gerbode defect. Real-time 3-dimensional echocardiography was used to accurately delineate the course of the shunt. To avoid overestimating right ventricular systolic pressure by mistaking such a shunt for an eccentric jet of tricuspid regurgitation, it is important to accurately differentiate the two. Real-time 3-dimensional echocardiography now provides rapid, detailed 3-dimensional appreciation of the origin and course of such shunts with easy facility of orienting views to the flows of interest by cropping. Such information can help design optimal surgical or catheter-based therapy. (J Am Soc Echocardiogr 2009;22:435.e1-e3.)

AB Many prescribe anticoagulants and antiplatelet medications to prevent thromboembolic events and access thrombosis in dialysis patients despite limited evidence of their efficacy in this population. This retrospective cohort study examined whether use of warfarin, clopidogrel, and/or aspirin affected survival in 41,425 incident hemodialysis patients during 5 yr of follow-up. The prescription frequencies for warfarin, clopidogrel, and aspirin were 8.3, 10.0, and 30.4%, respectively, during the first 90 d of initiating chronic hemodialysis. Compared with the 24,740 patients receiving none of these medications, Cox proportional hazards analysis suggested that exposure to these medications was associated with increased risk for mortality (warfarin hazard ratio [HR] 1.27 [95% confidence interval (CI) 1.18 to 1.37]; clopidogrel HR 1.24 [95% CI 1.13 to 1.35]; and aspirin HR 1.06 [95% CI 1.01 to 1.11]). The increased mortality associated with warfarin or clopidogrel use remained in stratified analyses. A covariate- and propensity-adjusted time-varying analysis, which accounted for longitudinal changes in prescription, produced similar results. In addition, matching for treatment facility and attending physician revealed similar associations between prescription and mortality. We conclude that warfarin, aspirin, or clopidogrel prescription is associated with higher mortality among hemodialysis patients. Given the possibility of confounding by indication, randomized trials are needed to determine definitively the risk and benefit of these medications.

AB Overexpression of the fatty acid synthase (FASN) gene has been implicated in prostate carcinogenesis. We sought to directly assess the oncogenic potential of FASN.
We used immortalized human prostate epithelial cells (iPrECs), androgen receptor-overexpressing iPrECs (AR-iPrEC), and human prostate adenocarcinoma LNCaP cells that stably overexpressed FASN for cell proliferation assays, soft agar assays, and tests of tumor formation in immunodeficient mice. Transgenic mice expressing FASN in the prostate were generated to assess the effects of FASN on prostate histology. Apoptosis was evaluated by Hoechst 33342 staining and by fluorescence-activated cell sorting in iPrEC-FASN cells treated with stimulators of the intrinsic and extrinsic pathways of apoptosis (ie, camptothecin and anti-Fas antibody, respectively) or with a small interfering RNA (siRNA) targeting FASN. FASN expression was compared with the apoptotic index assessed by the terminal deoxynucleotidyltransferase-mediated UTP end-labeling method in 745 human prostate cancer samples by using the least squares means procedure. All statistical tests were two-sided.
Forced expression of FASN in iPrECs, AR-iPrECs, and LNCaP cells increased cell proliferation and soft agar growth. iPrECs that expressed both FASN and androgen receptor (AR) formed invasive adenocarcinomas in immunodeficient mice (12 of 14 mice injected formed tumors vs 0 of 14 mice injected with AR-iPrEC expressing empty vector (P < .001, Fisher exact test); however, iPrECs that expressed only FASN did not. Transgenic expression of FASN in mice resulted in prostate intraepithelial neoplasia, the incidence of which increased from 10% in 8- to 16-week-old mice to 44% in mice aged 7 months or more (P = .0028, Fisher exact test), but not in invasive tumors. In LNCaP cells, siRNA-mediated silencing of FASN resulted in apoptosis. FASN overexpression protected iPrECs from apoptosis induced by camptothecin but did not protect iPrECs from Fas receptor-induced apoptosis. In human prostate cancer specimens, FASN expression was inversely associated with the apoptotic rate (mean percentage of apoptotic cells, lowest vs highest quartile of FASN expression: 2.76 vs 1.34, difference = 1.41, 95% confidence interval = 0.45 to 2.39, P(trend) = .0046).
These observations suggest that FASN can act as a prostate cancer oncogene in the presence of AR and that FASN exerts its oncogenic effect by inhibiting the intrinsic pathway of apoptosis.

AB Oncologists frequently approach patients to discuss difficult topics, such as bad news about cancer progression and referrals to palliative care and hospice. To communicate effectively in these difficult situations, it is helpful to assess what the patient knows and wants to know about their disease in general and, specifically, their prognosis. Although some patients fully accept the diagnosis of cancer and cope well, most patients struggle with how best to cope. This struggle often manifests itself with the patient vacillating between unrealistic hopes for longevity while also indicating prognostic awareness by talking about funeral plans. Although this coping is normal, it is difficult for most clinicians to interpret. This article presents a framework for understanding normal patient coping and gives specific examples of how to talk with these patients during difficult transitions, such as times of disease progression, and about referral to hospice and palliative care.

AB Background: Many patients are active smokers at the time of a diagnosis Of Surgically resectable lung cancer. Perioperative smoking cessation is associated with improved survival, but the cost-effectiveness of a smoking cessation program initiated immediately before surgery is unknown.
Methods: We developed a decision analytic Markov model to evaluate the incremental cost-effectiveness of a formal smoking cessation program. The parameter estimates were taken from the available literature. The model included the cost and effectiveness of the smoking cessation program, cost and incidence of perioperative complications, postoperative mortality, and utility measured in quality adjusted life years (QALY). Dollars per QALY and life year were calculated and one-way sensitivity analyses were performed.
Results: The cost/QALY and cost/life year were $16,415 and $45,629 at 1 year after surgery and $2609 and $2703 at 5 years, respectively. Most sensitivity analyses showed the 1 year postsurgery cost/QALY estimates were less than $50,000, and all were less than $12,000 at 5 years. Cost-effectiveness estimates were most sensitive to the frequency of perioperative complications and the estimated short-term utility estimates.
Conclusion: A smoking cessation program initiated before Surgical lung resection is cost-effective at both I and 5 years postsurgery. Providers should encourage patients who are still smoking to engage in formal smoking cessation programs.

AB Introduction: To determine the 1-year survival, response rate, and toxicity for patients with limited stage small cell lung cancer treated with the combination of cisplatin plus etoposide plus paclitaxel with delayed concurrent (starting with cycle 3) high dose thoracic radiotherapy.
Patients and Methods: Patients with previously untreated limited stage small cell lung cancer, Easter Cooperative Oncology Group performance status of 0-2 and adequate organ function were eligible. Cycles I and 2 of chemotherapy consisted of paclitaxel 170 mg/m(2) intravenous day 1, etoposide 80 mg/m(2) intravenous days I to 3, and cisplatin 60 mg/m(2) intravenous clay 1 followed by filgrastim 5 mu g/kg Subcutaneously days 4 to 13. Cycles 3 and 4 of chemotherapy consisted of a reduced close of paclitaxel 135 mg/m(2) intravenous day 1, and the same dose of etoposide and cisplatin with concurrent thoracic radiation therapy 1.8 Gy in 35 fractions (total 63 Gy) administered over 7 weeks.
Results: Sixty-three patients were entered, 61 patients were eligible. The most common grade 4 toxicity seen was granulocytopenia (62%). Nonhematologic toxicities included febrile neutropenia in 19% of patients, grade 3 and 4 esophagitis in 32% of patients, and grade 3 peripheral neuropathy in 14% of patients. Two patients suffered lethal toxicities. The overall response rate was 79%. The 1-year Survival rate was 64%. The median overall survival was 15.7 months, and the median progression-free survival was 8.6 months.
Conclusions: The combination of cisplatin plus etoposide plus paclitaxel chemotherapy and concurrent delayed thoracic radiotherapy as administered in this trial provide no apparent advantage with respect to response, local control, or Survival compared with historical controls.

ID LETHAL GROIN INJURY; HEMORRHAGE MODEL; LIVER-INJURY; BLOOD-LOSS; SWINE;
AGENT; DRESSINGS; SURVIVAL; BANDAGE
AB Background: Prehospital management of exsanguinating extremity injuries (EEI) includes direct compression or tourniquets or both. Direct compression may be ineffective in deep wounds and requires a person committed to compressing. Tourniquets may cause severe ischemic damage and may be ineffective in proximal wounds. This study aims to examine a new self-expanding hemostatic polymer (SEHP) for control of EEI. In contact with blood, the polymer absorbs the aqueous component of blood and exerts a tamponade effect by expanding against the walls of the wound cavity.
Methods: Twenty-one pigs were subjected to a validated and reproducible model of lethal proximal extremity injury by transecting soft tissues and the femoral vessels. The pigs were left to bleed uncontrollably for 3 minutes and then randomized to receive either a standard compression dressing (Control group, N = 10) or SEHP (SEHP group, N = 11). After 5 minutes of manual compression, the dressing or SEHP were left in the wound and the animals resuscitated more than 2 hours. One animal in each group died soon after the injury before application of the dressings and was removed from final analysis.
Results: SEHP animals had lower blood loss (1358 mL +/- 97 mL) than the Control animals (2028 mL +/- 177 mL, p = 0.006). The mortality was 55% in the Control group and 0% in the SEHP group (p = 0.006).
Conclusion: SEHP is a novel, light, and portable material to control EEI effectively. It does not require another person for compression nor does it compromise the circulation. As EEI occurs with alarming g frequency in the battlefield, SEHP may not only present an optimal hemostatic method for military applications but also be useful in the civilian prehospital setting.

TI Early Magnetic Resonance Imaging Is Unnecessary In Patients With
Traumatic Brain Injury
SO JOURNAL OF TRAUMA-INJURY INFECTION AND CRITICAL CARE

DT Article
DE Magnetic resonance imaging; Traumatic brain injury; head CT scan
ID MINOR HEAD-INJURY; COMPUTED-TOMOGRAPHY
AB Introduction: Computed tomography (CT) is routinely performed in traumatic brain injury (TBI). Magnetic resonance imaging (MRI) is considered more sensitive than CT for subtle abnormalities. Because CT does not always explain the posttraumatic neurologic examination, MRI is being performed with increasing frequency. Although MRI at a later stage may be of significant prognostic value, the role of early MRI is questionable. Our objective was to evaluate the role of early MRI in the initial management of patients with TBI.
Methods: This is a 3-year prospective study (January 2005-December 2007) of adult patients with TBI who, in addition to CT, had MRI of the head within 48 hours of admission to the hospital. The findings from the two imaging studies were compared. The outcome was any change in management based on MRI findings.
Results: We identified 123 trauma patients who had MRI within 18 hours +/- 14.5 hours of CT (median: 12 hours). In 82 (67%) patients, the findings of CT and MRI were identical. In the remaining 41 patients there were discrepancies between CT and MRI 35 patients had slight differences in the location or size of the lesions found and six had minor brain lesion detected by MRI and not CT. Compared with patients who had identical CT and MRI, those who showed differences in the two tests had higher severity of head in-jury, lower initial blood pressure, and a higher rate of intubation. Based on CT findings, 78 (63%) patients received TBI-related interventions: 8 craniotomies, 12 intracranial pressure monitoring catheters, 14 mannitol infusions, and 72 antiepileptic medications. There was no change in treatment because of MRI.
Conclusion: Early MRI may be superior to CT in describing subtle TBI findings, but this information does not affect management. Head CT is the only imaging test necessary in the first 48 hours after TBI.

AB Background: The mechanisms by which androgens ameliorate glucocorticoid-induced muscle wasting are still under investigation. In the present study, we tested the hypothesis that androgen's effects in reversing muscle wasting are related to activating the signaling pathways downstream of insulin-like growth factor-1 (IGF-I)/insulin.
Methods: Forty female Sprague-Dawley rats were randomly divided into four groups: control group, dexamethasone (DEX) group, testosterone (TES) group, and TES + DEX group. Each group was injected with saline or DEX (0.1 mg/100 g/d) for 10 days and sesame oil or TES (0.5 mg/100 g/d) for 13 days. Several downstream targets of IGF-I/insulin in skeletal muscle including protein kinase B (Akt), p70 ribosomal protein S6 kinase (p70S6K), and glycogen synthase kinase-3 beta (GSK-3 beta) that are associated with protein synthesis were examined. Two proteolysis-related ubiquitin E3-ligases, muscle atrophy F-box, and muscle RING finger-1 that are also regulated by IGF-I/insulin were also assessed.
Results: TES attenuated gastrocnemius muscle atrophy induced by DEX. TES prevented the DEX-induced decrease of IGF-I expression in gastrocnemius muscle, but not in serum. TES ameliorated DEX-induced dephosphorylation of Akt and p70S6K and promoted the phosphorylation of GSK-3 beta in gastrocnemius muscle. The total amount of Akt, p70S6K, or GSK-3 beta proteins was not changed among these groups. TES did not show any effects on the DEX-induced upregulation of muscle atrophy F-box, and muscle RING finger-I mRNA in gastrocnemius muscle.
Conclusion: This findings suggest that the effects of TES in reversing DEX-induced muscle atrophy are related to signaling pathways downstream of IGF-I/insulin that are associated with protein synthesis.

ID UNENHANCED HELICAL CT; INTRAVENOUS UROGRAPHY; URETERAL CALCULI; PASSAGE
AB Purpose: We determined the most accurate method of measuring urinary stones on computerized tomography.
Materials and Methods: For the in vitro portion of the study 24 calculi, including 12 calcium oxalate monohydrate and 12 uric acid stones, that had been previously collected at our clinic were measured manually with hand calipers as the gold standard measurement. The calculi were then embedded into human kidney-sized potatoes and scanned using 64-slice multidetector computerized tomography. Computerized tomography measurements were performed at 4 window settings, including standard soft tissue windows (window width-320 and window length-50), standard bone windows (window width-1120 and window length-300), 5.13x magnified soft tissue windows and 5.13x magnified bone windows. Maximum stone dimensions were recorded. For the in vivo portion of the study 41 patients with distal ureteral stones who underwent noncontrast computerized tomography and subsequently spontaneously passed the stones were analyzed. All analyzed stones were 100% calcium oxalate monochydrate or mixed, calcium based stones. Stones were prospectively collected at the clinic and the largest diameter was measured with digital calipers as the gold standard. This was compared to computerized tomography measurements using 4.0x magnified soft tissue windows and 4.0x magnified bone windows. Statistical comparisons were performed using Pearson's correlation and paired t test.
Results: In the in vitro portion of the study the most accurate measurements were obtained using 5.13x magnified bone windows with a mean 0.13 mm difference from caliper measurement (p = 0.6). Measurements performed in the soft tissue window with and without magnification, and in the bone window without magnification were significantly different from hand caliper measurements (mean difference 1.2, 1.9 and 1.4 mm, p = 0.003, <0.001 and 0.0002, respectively). When comparing measurement errors between stones of different composition in vitro, the error for calcium oxalate calculi was significantly different from the gold standard for all methods except bone window settings with magnification. For uric acid calculi the measurement error was observed only in standard soft tissue window settings. In vivo 4.0x magnified bone windows was superior to 4.0x magnified soft tissue windows in measurement accuracy. Magnified bone window measurements were not statistically different from digital caliper measurements (mean underestimation vs digital caliper 0.3 mm, p = 0.4), while magnified soft tissue windows were statistically distinct (mean underestimation 1.4 mm, p = 0.001).
Conclusions: In this study magnified bone windows were the most accurate method of stone measurements in vitro and in vivo. Therefore, we recommend the routine use of magnified bone windows for computerized tomography measurement of stones. In vitro the measurement error in calcium oxalate stones was greater than that in uric acid stones, suggesting that stone composition may be responsible for measurement inaccuracies.

AB Percutaneous acetabuloplasty (PA) is a promising treatment for painful metastatic lesions of the acetabulum. Four patients were treated with injection of the bone cement polymethylmethacrylate directly into the lesion. After the procedure, all four patients had improvement or relief of their pain and were able to resume weight-bearing activities. The procedure was well tolerated by each patient without morbidity. PA appears to be a reasonable palliative procedure for painful and fragile hips associated with metastatic bone disease.

AB Important questions remain on the role of T cells in progression of hepatitis virus-mediated liver pathogenesis: are T cells 'Good or Bad'? How could one maintain a beneficial balance, in which regulatory T-cell (Treg) populations might play an important role? Treg are a heterogeneous population of cells, including the classical CD4+CD25+ subset expressing the transcription factor Foxp3, CD4 T cells secreting IL-10 (Tr1) or TGF-beta (Th3), but also some CD8 T cells, double negative T cells and gamma delta T cells. The role of Treg in viral hepatitis, particularly HBV and HCV, seems to range from suppressing T-cell responses directed against hepatitis viruses to down-regulating the immune responses causing the liver damage. Questions also remain unresolved on which Treg populations are important and how to establish a beneficial balance, mostly due to the difficulties in studying the heterogeneous Treg populations but also due to the problem accessing liver, the principal target of hepatitis viruses. Here, we will review progress to date on understanding Treg populations in regard to viral hepatitis.

AB The HEK293T human embryonic kidney cells have been used widely as a packaging host for transfection-based production of recombinant lentiviruses. The present study describes advantages of using COS-1 African green monkey kidney cells versus HEK293T cells as a packaging host for small-volume production of high-quality recombinant lentiviruses. The particle performance index, defined as the ratio of infection-competent viral particles to the total number of particles, was three- to four-fold greater in transfection supernatants generated using COS-1 cells than that generated using HEK293T cells. Adhesion of HEK293T cells to the cell culture-treated plastic surface was weak, causing significant HEK293T cell contamination in the transfection supernatants produced by laboratory automation using the 96-well cell culture plates. In contrast, COS-1 cells adhered strongly to the plastic surface, and cell contamination was not detected in the transfection supernatants. These results suggest that COS-1 cells may be a useful alternative packaging host for use for automated generation of large numbers of high-quality lentivirus reagents, particularly because they eliminate the need for additional purification steps to remove viral particles from cell culture supernatant.

AB Defining the antiviral efficacy of CD8 T cells is important for immunogen design, and yet most current assays do not measure the ability of responses to neutralize infectious virus. Here we show that human immunodeficiency virus (HIV)-specific cytotoxic T-lymphocyte (CTL) clones and cell lines derived from infected persons and targeting diverse epitopes differ by over 1,000-fold in their ability to retard infectious virus replication in autologous CD4 T cells during a 7-day period in vitro, despite comparable activity as assessed by gamma interferon (IFN-gamma) enzyme-linked immunospot (ELISPOT) assay. Cell lines derived from peripheral blood mononuclear cells stimulated in vitro with peptides representing targeted Gag epitopes consistently neutralized HIV better than Env-specific lines from the same person, although ineffective inhibition of virus replication is not a universal characteristic of Env-specific responses at the clonal level. Gag-specific cell lines were of higher avidity than Env-specific lines, although avidity did not correlate with the ability of Gag- or Env-specific lines to contain HIV replication. The greatest inhibition was observed with cell lines restricted by the protective HLA alleles B*27 and B*57, but stimulation with targeted Gag epitopes resulted in greater inhibition than did stimulation with targeted Env epitopes even in non-B*27/B*57 subjects. These results assessing functional virus neutralization by HIV-specific CD8 T cells indicate that there are marked epitope- and allele-specific differences in virus neutralization by in vitro-expanded CD8 T cells, a finding not revealed by standard IFN-gamma ELISPOT assay currently in use in vaccine trials, which may be of critical importance in immunogen design and testing of candidate AIDS vaccines.

AB Elite controllers (EC) of human immunodeficiency virus type 1 (HIV-1) maintain viremia below the limit of detection without antiretroviral treatment. Virus-specific cytotoxic CD8(+) T lymphocytes are believed to play a crucial role in viral containment, but the degree of immune imprinting and compensatory mutations in EC is unclear. We obtained plasma gag, pol, and nef sequences from HLA-diverse subjects and found that 30 to 40% of the predefined HLA-associated polymorphic sites show evidence of immune selection pressure in EC, compared to approximately 50% of the sites in chronic progressors. These data indicate ongoing viral replication and escape from cytotoxic T lymphocytes are present even in strictly controlled HIV-1 infection.

AB Objective: The objective was to describe the healthcare and information-seeking behavior of women with self-reported sexual problems and accompanying sexually related personal distress identified from a large, population-based U. S. survey.
Methods: Women (n = 3,239) aged >= 18 years with self-reported sexual problems of desire, arousal, and/or orgasm accompanied by sexually related personal distress were identified from a cross-sectional mailed survey of 50,002 U. S. households sampled from a national research panel. Healthcare and information-seeking behavior was examined as four ordered categories: sought formal medical advice, sought informal advice, sought information from anonymous sources, and did not seek help or information. Correlates of help seeking for each type of distressing sexual problem were modeled with multivariable proportional odds regression.
Results: Just over a third of women with any distressing sexual problems had sought formal care, most often from a gynecologist or primary care physician; about 80% of the time, the woman, rather than the physician, initiated the conversation. Only 6% of women who sought medical advice scheduled a visit specifically for a sexual problem. Factors related to help seeking were having a current partner and interacting with the heathcare system. Barriers were poor self-perceived health and embarrassment about discussing sexual topics with a physician.
Conclusions: Our results suggest inadequacies in the U. S. medical care system in addressing sexual problems in women. Gynecologists and primary care physicians, by including discussions about sexual health during routine visits, can increase the likelihood that adequate care can be offered.

AB Few studies have examined the risk of multiple or high doses of combined central nervous system (CNS) medication use for recurrent falls in the elderly. The study objective was to evaluate whether multiple- or high-dose CNS medication use in older adults was associated with a higher risk of recurrent (>= 2) falls.
This longitudinal cohort study included 3,055 participants from the Health, Aging and Body Composition study who were well functioning at baseline. CNS medication use (benzodiazepine and opioid receptor agonists, antipsychotics, antidepressants) was determined annually (except Year 4) during in-person interviews. The number and summated standard daily doses (SDDs; low, medium, and high) of CNS medications were computed. Falls 1 year later were ascertained annually for 5 years.
For a period of 5 years, as many as 24.1% of CNS medication users took 2+ agents annually, whereas as no more than 18.9% of CNS medication users took high doses annually (3+ SDDs). Yearly, as many as 9.7% of participants reported recurrent falls. Multivariable Generalized Estimating Equation analyses showed that multiple CNS medication users compared with never users had an increased risk of sustaining 2+ falls (adjusted odds ratio [OR] 1.95; 95% confidence interval [CI] 1.35-2.81). Those taking high (3+) CNS SDDs also exhibited an increased risk of 2+ falls (adjusted OR 2.89; 95% CI 1.96-4.25).
Higher total daily doses of CNS medications were associated with recurrent falls. Further studies are needed to determine the impact of reducing the number of CNS medications and/or dosage on recurrent falls.

AB Background Most patients admitted for acute heart failure have normal or increase blood pressure. Relaxin is a natural human peptide that affects multiple vascular control pathways, suggesting potential mechanisms of benefit for such patients. We assessed the dose response of relaxin's effect on symptom relief, other clinical outcomes, and safety.
Methods In a placebo-controlled, parallel-group, dose-ranging study, 234 patients with acute heart failure, dyspnoea, congestion on chest radiograph, and increased brain natriuretic peptide (BNP) or N-terminal prohormone of BNP, mild-to-moderate renal insufficiency, and systolic blood pressure greater than 125 mm Hg were recruited from 54 sites in eight countries and enrolled within 16 h of presentation. Patients were randomly assigned, in a double-blind manner via a telephone-based interactive voice response system, to standard care plus 48-h intravenous infusion Of placebo (n=62) or relaxin 10 mu g/kg (n=40), 30 mu g/kg (n=43), 100 mu g/kg (n=39), or 250 mu g/kg (n=50) per day. Several clinical endpoints were explored to assess whether intravenous relaxin should be pursued in larger studies of acute heart failure, to identify an optimum dose, and to help to assess endpoint selection and power calculations. Analysis was by modified intention to treat. This study is registered with ClinicalTrials.gov, number NCT00520806.
Findings In the modified intention-to-treat population, 61 patients were assessed in the placebo group, 40 in the relaxin 10 mu g/kg per day group, 42 in the relaxin 30 mu g/kg per day group, 37 in the relaxin 100 mu g/kg per day group, and 49 in the relaxin 250 mu g/kg per day group. Dyspnoea improved with relaxin 30 mu g/kg compared with placebo, as assessed by Likert scale (17 of 42 patients [40%] moderately or markedly improved at 6 h, 12 h, and 24 h vs 14 of 61 [23%]; p=0.044) and visual analogue scale through day 14 (8214 mmxh [SD 87121 vs 4622 mmxh [90031; p=0.053). Length of stay was 10.2 days (SD 6.1) for relaxin-treated patients versus 12.0 days (7.3) for those given placebo, and days alive out of hospital were 47.9 (10.1) versus 44.2 (14.2). Cardiovascular death or readmission due to heart or renal failure at day 60 was reduced with relaxin (2.6% [95% Cl 0.4-16.8] vs 17.2% [9.6-29.6]; p=0.053). The number of serious adverse events was similar between groups.
Interpretation When given to patients with acute heart failure and normal-to-increased blood pressure, relaxin was associated with favourable relief of dyspnoea and other clinical outcomes, with acceptable safety.

AB Objectives/Hypothesis: Determine the incidence and characterize perioperative airway complications in patients who have undergone medialization thyroplasty (MT) and subsequently undergo procedures requiring anesthesia.
Study Design: Retrospective review of post-MT anesthesia encounters in a large academic hospital.
Methods: A series of post-MT patients was reviewed, identifying anesthesia encounters undergoing endotracheal intubation (ETI) or laryngeal mask airway (LMA) placement. Details on the perioperative course of each encounter were extracted and examined for evidence of airway complications. The incidence of airway obstruction and need for airway intervention were determined and compared to those of control patients matched for type of procedure. Relationships between complications and perioperative management were analyzed.
Results: A total of 74 anesthesia encounters were identified among 219 post-MT patients. Perioperative airway complications among post-MT patients arose in five procedures (6.8%; 95% CI: 1.0-12.4%). Stridor in the operating or recovery room was exhibited three times, with all episodes requiring nebulized racemic epinephrine and intravenous steroids for resolution of symptoms. One patient underwent an urgent tracheotomy for severe stridor leading to airway compromise in the recovery room. Immediately after induction with an LMA, one patient failed to maintain oxygen saturations above 90% and consequently required conversion to ETI. Among 79 matched controls without prior MT, no perioperative complications (0%) occurred (P = .027).
Conclusions: The incidence of perioperative airway complications in post-MT patients is non-neglible and may be serious. Surgical, anesthesia, and recovery room staff should be made aware of the significantly increased risk of airway complications in post-MT patients.

AB Objectives/Hypothesis: To explore adipose-derived stem cell/fibroblast interactions as a potential remodeling pathway for vocal fold scar.
Study Design: Fibroblasts and adipose-derived stem/stromal cells (ASCs) were cultured alone and in combination in a cell-contact-independent paracrine system. Analyses of cell proliferation, and the production of hyaluronic acid (HA) and collagen were performed on samples collected on days 1, 3, and 7.
Methods: Normal fibroblasts (NFs) were isolated bilaterally from the subepithelial lamina propria of two normal ferret vocal folds. Scar fibroblasts (SFs) were isolated from vocal folds that were electrocauterized 2 weeks before harvest. ASCs were isolated from lipoaspirated subcutaneous abdominal fat of two ferrets. A transwell cell-contact-independent cell communication culturing system was used for coculture experiments. Cells were seeded at 50,000/well in both monoculture and coculture experiments.
Results: In monoculture, SFs proliferated faster and produced less HA and more collagen than NFs at day 7 (P < .05). In SF/ASC coculture, SF proliferation was diminished and collagen production at day 7 decreased (P < .05). HA production did not differ between monoculture and coculture conditions.
Conclusions: Normal and scar-tissue-derived vocal fold fibroblasts maintain phenotypic differences in culture, thus validating this in vitro scar model. In between SFs and ASCa, leading to less collagen secretion. The data support the hypothesis that ASCs can induce favorable remodeling of scarred vocal folds in vivo by their interactions with endogenous fibroblasts.

AB Background and Objective: Low level light therapy (LLLT) is being evaluated for treating chronic and acute pain associated with rheumatoid arthritis (RA) and other inflammatory diseases. The mechanisms underlying the effectiveness of LLLT for pain relief in RA are not clear. The objectives of this study were to determine whether LLLT decreased production of pro-inflammatory cytokines by cells from RA joints, and, if so, to identify cellular mechanisms.
Study Design/Materials and Methods: Synoviocytes from RA patients were treated with 810 nm radiation before or after addition of tumor necrosis factor-alpha (TNF-alpha). mRNA for TNF-alpha, interleukin (IL)-1 beta, IL-6, and IL-8 was measured after 30, 60, and 180 minutes using RT-PCR. Intracellular and extracellular protein levels for 12 cytokines/chemokines were measured at 4, 8, and 24 hours using multiplexed ELISA. NF-kappa B activation was detected using Western blotting to follow degradation of I kappa B alpha and nuclear localization of the p65 subunit of NF-kappa B.
Results: Radiation at 810 nm (5 J/cm(2)) given before or after TNF-alpha decreases the mRNA level of TNF-alpha and IL-1 beta in RA synoviocytes. This treatment using 25 J/cm2 also decreases the intracellular levels of TNF-alpha, IL-1 beta, and IL-8 protein but did not affect the levels of seven other cytokines/ chemokines. TNF-alpha-induced activation of NF-kappa B is not altered by 810 nm radiation using 25 J/cm(2).
Conclusions: The mechanism for relieving joint pain in RA by LLLT may involve reducing the level of proinflammatory cytokines/chemokines produced by synoviocytes. This mechanism may be more general and underlie the beneficial effects of LLLT on other inflammatory conditions. Lasers Surg. Med. 41:282-290, 2009. (C) 2009 Wiley-Liss, Inc.

AB We propose a model for HCMV infection in healthy and immunosuppressed patients. First, we present the biological model and formulate a system of ordinary differential equations to describe the pathogenesis of primary HCMV infection in immunocompetent and immunosuppressed individuals. We then investigate how clinical data can be applied to this model. Approximate parameter values for the model are derived from data available in the literature and from mathematical and physiological considerations. Simulations with the approximated parameter values demonstrates that the model is capable of describing primary, latent, and secondary (reactivated) HCMV infection. Reactivation simulations with this model provide a window into the dynamics of HCMV infection in (D-R+) transplant situations, where latently-infected recipients (R+) receive transplant tissue from HCMV-naive donors (D-).

AB TNF-alpha-mediated apoptosis is enhanced in aged rodent muscles, suggesting that this pathway may be involved in sarcopenia. Interleukin-15 (IL-15), a muscle-derived anabolic cytokine, mitigates muscle wasting and apoptosis in cachectic rats. This effect is thought to occur through inhibition of TNF-alpha-triggered apoptosis. We investigated IL-15 signaling and the TNF-a-mediated pathway of apoptosis in the gastrocnemius muscle of Fischer344xBrown Norway rats across the ages of 8, 18, 29 and 37 months, in relation to life-long calorie restriction (CR, 40% calorie intake reduction). Aging caused loss of muscle mass and increased apoptotic DNA fragmentation, which were mitigated by CR. Protein levels of IL-15 and mRNA abundance of IL-15 receptor a-chain decreased in senescent ad libitum (AL) fed rats, but were maintained in CR rodents. Elevations of TNF-alpha, TNF-receptor 1, cleaved caspase-8 and -3 were observed at advanced age in AL rats. These changes were prevented or mitigated by CR. Our results indicate that aging is associated with decreased IL-15 signaling in rat gastrocnemius muscle, which may contribute to sarcopenia partly through enhanced TNF-a-mediated apoptosis. Preservation of IL-15 signaling by CR may therefore represent a further mechanism contributing to the anti-aging effect of this dietary intervention in skeletal muscle.

AB Objectives: To examine factors associated with oversupply and undersupply of antihypertensive medication, and examine evidence for medication acquisition as distinct from self-reported adherence.
Research Design: Analysis of pharmacy refill records, medical charts, and in-person interviews.
Subjects: Five hundred sixty-two male veterans with hypertension enrolled in a randomized controlled trial to improve BP control.
Measures: Patients were classified as having undersupply (<0.80), appropriate supply (>= 0.80 and <= 1.20), or oversupply (>1.20) of antihypertensive medication in the 90 days before trial enrollment based on the ReComp algorithm. Determination of BP control was based on clinic measurements at enrollment. Demographic, clinical, psychosocial, and behavioral factors relevant to medication-taking behavior and BP were assessed at enrollment.
Results: Twenty-three percent of the patients had undersupply, 47% had appropriate Supply, and 30% had oversupply of antihypertensive medication. Multinomial logistic regression revealed that using fewer classes of antihypertensive medications and greater perceived adherence barriers were independently associated with greater likelihood of undersupply. Current employment was associated with decreased likelihood of oversupply, and greater comorbidity and being married were associated with increased likelihood of oversupply. Agreement between ReComp and self-reported adherence was poor (kappa = 0.19 P < 0.001). Undersupply, oversupply, and self-reported nonadherence were all independently associated with decreased likelihood of BP control after adjusting for each other and patient factors.
Conclusions: Antihypertensive oversupply was common and may arise front different circumstances than Undersupply. Measures of medication acquisition and self-reported adherence appear to provide distinct, complementary information about patients' medication-taking behavior.

AB As health care systems seek to provide patient-centered care as a cornerstone of quality, how to measure this aspect of quality has become a concern. Previous development of quality indicators for treating individual chronic disease has rarely included patient perspectives on quality of care. Using epilepsy as an exemplar, the authors sought to develop an approach to measuring patient-centered quality of care. They conducted six focus groups with adults with epilepsy. Using qualitative methods, the authors initially identified 10 patient-generated quality indicators, 5 of which were subsequently rated, along with literature-based quality indicators, by an expert panel using a modified RAND appropriateness methodology. The authors discuss similarities and differences in aspects of care patients and providers value as essential for good quality. The process presented in this article may serve as a model for incorporating patient perceptions of quality into the future development of quality indicators for chronic diseases.

AB Surface imaging is in use in radiotherapy clinical practice for patient setup optimization and monitoring. Breast alignment is accomplished by searching for a tentative spatial correspondence between the reference and daily surface shape models. In this study, the authors quantify whole breast shape alignment by relying on texture features digitized on 3D surface models. Texture feature localization was validated through repeated measurements in a silicone breast phantom, mounted on a high precision mechanical stage. Clinical investigations on breast shape alignment included 133 fractions in 18 patients treated with accelerated partial breast irradiation. The breast shape was detected with a 3D video based surface imaging system so that breathing was compensated. An in-house algorithm for breast alignment, based on surface fitting constrained by nipple matching (constrained surface fitting), was applied. Results were compared with a commercial software where no constraints are utilized (unconstrained surface fitting). Texture feature localization was validated within 2 mm in each anatomical direction. Clinical data show that unconstrained surface fitting achieves adequate accuracy in most cases, though nipple mismatch is considerably higher than residual surface distances (3.9 mm vs 0.6 mm on average). Outliers beyond 1 cm can be experienced as the result of a degenerate surface fit, where unconstrained surface fitting is not sufficient to establish spatial correspondence. In the constrained surface fitting algorithm, average surface mismatch within 1 mm was obtained when nipple position was forced to match in the [1.5; 5] mm range. In conclusion, optimal results can be obtained by trading off the desired overall surface congruence vs matching of selected landmarks (constraint). Constrained surface fitting is put forward to represent an improvement in setup accuracy for those applications where whole breast positional reproducibility is an issue.

AB Background: The use of chromium-containing dietary supplements is widespread among patients with type 2 diabetes. Chromium's effects in patients at high risk for developing diabetes, especially those with metabolic syndrome, is unknown. The objective of this study was to determine the effects of chromium picolinate (CrPic) on glucose metabolism in patients with metabolic syndrome.
Method: A double-blind, placebo-controlled, randomized trial was conducted at a U. S. academic medical center. Sixty three patients with National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III)-defined metabolic syndrome were included. The primary end point was a change in the insulin sensitivity index derived from a frequently sampled intravenous glucose tolerance test. Prespecified secondary end points included changes in other measurements of glucose metabolism, oxidative stress, fasting serum lipids, and high sensitivity C-reactive protein.
Results: After 16 weeks of CrPic treatment, there was no significant change in insulin sensitivity index between groups (P = 0.14). However, CrPic increased acute insulin response to glucose (P = 0.02). CrPic had no significant effect on other measures of glucose metabolism, body weight, serum lipids, or measures of inflammation and oxidative stress.
Conclusion: CrPic at 1000 mu g/day does not improve key features of the metabolic syndrome in obese nondiabetic patients.

AB Recent studies have demonstrated an association between retinol-binding protein (RBP4) and insulin resistance. Retinol-binding protein is decreased in women and elevated in polycystic ovary syndrome. However, prior studies have not investigated the relationship between RBP4, gonadal steroids, and gonadotropins in healthy women. The aim of this study was to determine the RBP4 levels in a cohort of healthy women with a range of body mass indices and glucose tolerances to investigate the relationship between RBP4, gonadotropin levels, and menopausal status. Serum RBP4 levels were measured by enzyme-linked immunosorbent assay and quantitative Western blot in 88 healthy women (aged 24-59 years) from the general community in a cross-sectional study. Retinol-binding protein was higher in postmenopausal compared with premenopausal women (26.1 +/- 2.1 vs 19.3 +/- 0.5 mu g/mL, P = .001). In univariate analysis, RBP4 was associated with follicle-stimulating hormone (r = 0.37, P = .0004), luteinizing hormone (r = 0.3, P = .005), and sex hormone-binding globulin (r = 0.24, P = .03) and trended to significance with estradiol (P = .09) but not with free testosterone or dehydroepiandrosterone sulfate. Retinol-binding protein was also associated with insulin at 2 hours during an oral glucose tolerance test (r = 0.24, P = .03) and the area under the curve for insulin during the oral glucose tolerance test (r = 0.26, P = .02). In multivariate regression modeling, both follicle-stimulating hormone (P = .03) and luteinizing lion-none (P = .04) remained significantly associated with RBP4 after controlling for estradiol, sex hormone-binding globulin, insulin area under the curve, cholesterol, triglycerides, waist-to-hip ratio, and tumor necrosis factor a. Retinol-binding protein was not associated with inflammatory markers or with carotid intima-media thickness. Therefore, RBP4 is higher in postmenopausal women and is associated with gonadotropin concentrations in healthy women. (C) 2009 Elsevier Inc. All rights reserved.

AB A prospective interventional study of pulsatile intravenous insulin infusion therapy has demonstrated reduction of left ventricular mass and blunting of progression of diabetic nephropathy. We anticipated that improvements in objective parameters would be associated with similar improvement measurable by the self-administered Diabetes Impact Management Scale (DIMS). The DIMS was administered at baseline and 12 months for 19 participants randomized to receive either standard insulin treatment of 3 to 4 injections of insulin daily or insulin treatment plus an additional day per week of 3 intravenous pulses over an 8 hour period. For standard vs pulsed intravenous insulin therapy, mean baseline scores were similar for the 12 total questions as well as the groups of 7 questions with emotional content and 5 with physical (neurologic) content. Mean study group scores at 1 year and changes over 1 year were not significantly different for the 7 questions with emotional content (P = .3143, .7574). Score results for the 5 questions related to neurologic status at 1 year and changes over 1 year were significantly different between patients with standard and with pulsed insulin therapy (P = .0144, 0.0004). Pulsatile intravenous insulin, when added to standard multiple-dose insulin therapy, was demonstrated to improve subjective perception of neurologic disability on repeated use of an abbreviated form of the DIMS.

AB A prospective study involving the use of the Diabetes Impact Management Scale (DIMS) in individuals with diabetic nephropathy as part of an interventional study of pulsatile intravenous insulin infusion therapy is used to define the utility of repeated subjective DIMS testing. We hypothesized that repeated use of such an evaluation would correlate well with other objective end points. The DIMS was administered at baseline and 12 months for 19 participants randomized to receive either standard insulin treatment of 3 to 4 injections of insulin daily or standard insulin treatment plus an additional day per week of 3 intravenous pulses over an 8-hour period. Measures of glycemic control, renal function, hemostatic factors, hemodynamics, left ventricular mass, and function were assessed at baseline and 12 months. Of 44 questions on impact of diabetes management, only 12(5 reflecting physical and 7 reflecting emotional status) showed significant change from baseline to 1 year. Changes in the 5 physical questions related to neurologic status correlated with stable creatinine (P = .0001). stable creatinine clearance (P = .0001), and decrease in left ventricular hypertrophy (P = .0117). Repeated use of an abbreviated, standardized subjective instrument uncovered changes in quality of life that correlated with differences in renal function and left ventricular mass over 12 months. Further use of such and instrument may help us focus treatment for maximum impact. (C) 2009 Elsevier Inc. All rights reserved.

AB Apolipoprotein As (APOA5) is expressed primarily in the liver and modulates plasma triglyceride levels in mice and humans. Mice overexpressing APOA5 exhibit reduced plasma trigglyceride levels. Because there is a tight association between plasma triglyceride concentration and traits of the metabolic syndrome, we used transgenic mice overexprcssing human APOA5 to test the concept that these Mice would be protected from diet-induced obesity and insulin resistance. Male and female transgenic and wild-type mice on the FVB/N genetic background were fed standard rodent chow or a diet rich in fat and sucrose for 18 weeks, during which time clinical phenotypes associated with obesity and glucose homeostasis were measured. We found that APOA5 transgenic (A5tg) mice were resistant to diet-induced changes in plasma triglyceride but not total cholesterol levels. Body weights were similar between the genotypes for females and males, although male A5tg mice showed a modest but significant increase in the relative size of inguinal fat pads. Although male A5tg mice showed a significantly increased ratio of plasma glucose to insulin, profiles Of glucose clearance as evaluated after injections of glucose or insulin failed to reveal any differences between genotypes, Overall, our data showed that there was no advantage to responses to diet-induced obesity with chronic reduction of plasma triglyceride levels as mediated by overexpression of APOA5.

AB Significant advances have transpired in the human immunodeficiency Virus type I (HIV-1) integration field in recent years. Considering its essential nature, integrase has long been a target of interest for antiviral drug development. The most significant advance was the approval of the Merck compound raltegravir, the first licensed integrase inhibitor, in October 2007. Another milestone was the identification and characterization of specific nucleoprotein complexes that mediate integrase 3' processing and DNA strand transfer activities in vitro. Genome-wide distribution analyses have furthermore revealed that different retroviruses differentially target distinctive regions of chromatin during integration. For examples, lentiviruses favor actively transcribed genes whereas gammaretroviruses Such as Moloney murine leukemia virus prefer transcriptional start sites. Though the underlying mechanisms are unknown for most retroviruses, the lentiviral preference is in large part guided through the interaction with the integrase binding protein lens epithelium-derived growth factor (LEDGF)/p75. Experimental methods that formed the foundations for each of these advances, as well as other techniques topical to the study of HIV-1 integration, are described in this issue of Methods.

AB Transfer of antigen-specific T cells into antigen-expressing lymphopenic recipients leads to the sequential generation of Th1 and Th17 effector and protective CD25(+)FoxP3(+) regulatory cells in the periphery with surprisingly different kinetics. Such an experimental model is potentially valuable for defining the stimuli that regulate lineage decision and plasticity of various T cell effectors and peripheral regulatory T cells. Our studies have shown that IL-17 production occurs rapidly and declines within the first week with the appearance of IFN-gamma producing T cells. Regulatory T cells appear during the recovery phase of the disease. The factors that mediate this complex differentiation originating from a starting naive T cell population remain to be defined.

AB The histological features of atypical hidradenoma are worrisome for increased risk of recurrence and possible malignant potential; however, earlier studies with immunohistochemistry or patient follow-up have not been reported. In addition, immunohistochemical analysis of hidradenocarcinoma exists in the literature mainly as case reports and as a single series of six cases. We compare the histological features and Ki-67, phosphorylated histone H3, epidermal growth factor receptor, and Her2/neu expression profiles of 15 atypical and 15 malignant hidradenomas with those of benign hidradenoma and metastasizing adnexal carcinomas. Infiltrative growth pattern, deep extension, necrosis, nuclear pleomorphism, and >= 4 mitoses per 10 high-power fields are specific features of hidradenocarcinomas. Significant difference in mean Ki-67% was observed between benign and malignant hidradenomas (P < 0.001), benign and metastasizing adnexal carcinomas (0.002), atypical and malignant hidradenomas (P < 0.001), and between atypical hidradenomas and metastasizing adnexal carcinomas ( 0.002). Significant difference in mean phosphorylated histone H3% was observed between benign and malignant hidradenomas (P < 0.001), benign and metastasizing adnexal carcinomas (0.003), atypical and malignant hidradenomas (P < 0.001), and between atypical hidradenomas and metastasizing adnexal carcinomas (P < 0.001). Mean epidermal growth factor receptor total score was significantly different in benign and atypical hidradenoma when compared with that in metastasizing adnexal carcinoma (P=0.014 and 0.019, respectively). Equivocal or 2+ Her2/neu positivity was observed in one hidradenocarcinoma and in two metastasizing adnexal carcinomas. Receiver operating characteristic curve analysis for Ki-67 and phosphorylated histone H3% positivity reveals statistically significant criterion values of > 11.425 and > 0.7, respectively, for distinguishing malignant hidradenomas from atypical hidradenomas. Despite the presence of some worrisome histological features, the significantly different immunoprofile from the malignant counterpart suggests that atypical hidradenomas are likely to recur but are unlikely to metastasize. A tumor with Ki-67 > 11% and/or phosphorylated histone H3 > 0.7% would likely be a malignant rather than an atypical hidradenoma. The infrequent Her2/neu overexpression in hidradenocarcinoma suggests its limited therapeutic role.

AB Membrane type-1 matrix metalloproteinase (MT1-MMP) supports tumor cell invasion through extracellular matrix barriers containing fibrin, collagen, fibronectin, and other proteins. Here, we show that simultaneous knockdown of two or three members of the tetraspanin family (CD9, CD81, and TSPAN12) markedly decreases MT1-MMP proteolytic functions in cancer cells. Affected functions include fibronectin proteolysis, invasion and growth in three-dimensional fibrin and collagen gels, and MMP-2 activation. Tetraspanin proteins (CD9, CD81, and TSPAN2) selectively coimmunoprecipitate and colocalize with MT1-MMP. Although tetraspanins do not affect the initial biosynthesis of MT1-MMP, they do protect the newly synthesized protein from lysosomal degradation and support its delivery to the cell surface. Interfering with MT1-MMP-tetraspanin collaboration may be a useful therapeutic approach to limit cancer cell invasion and metastasis.

AB Both the Ku subunit of the DNA-dependent protein kinase (DNA-PK) and the facilitator of chromatin transcription (FACT) complex reportedly bind cisplatin-DNA adducts. For this study, we developed an immunocytochemical assay based on detergent extraction allowing unveiling nucleolar subpopulations of proteins present in both the nucleoplasm and the nucleolus. Immunofluorescence analysis in various human cancer cell lines and immunoblotting of isolated nucleoli show that DNA-PK catalytic subunit (DNA-PKcs), Ku86, the Werner syndrome protein (WRN), and the structure-specific recognition protein 1 (SSRP1) subunit of FACT colocalize in the nucleolus and exit the nucleolus after cisplatin treatment. Nucleolar localization of Ku is also lost after y or UV irradiation and exposure to DNA-damaging drugs, such as actinomycin D, mitomycin C, hydroxyurea, and doxorubicin. Ku86 and WRN leave the nucleolus after exposure to low (>1 mu g/mL) doses of cisplatin. In contrast, the SSRP1 association with the nucleolus was disrupted only by high (50-100 mu g/mL) doses of cisplatin. Both cisplatin-induced loss of nucleolar SSRP1 and DNA-PK activation are suppressed by pretreatment of the cells with wortmannin or the DNA-PK inhibitor NU7026 but not by the phosphatidylinositol 3-kinase inhibitor LY294002. In the same conditions, kinase inhibitors did not alter the exit of DNA-PKcs and WRN, suggesting that different mechanisms regulate the exit of DNA-PK/WRN and FACT from the nucleolus. Furthermore, RNA silencing of DNA-PKcs blocked the cisplatin-induced exit of nucleolar SSRP1. Finally, silencing of DNA-PKcs or SSRP1 by short hairpin RNA significantly increased the sensitivity of cancer cells to cisplatin. (Mol Cancer Res 2009;7(4):581-91)

AB The impact of disease-causing defects is often not limited to the products of a mutated gene but, thanks to interactions between the molecular components, may also affect other cellular functions, resulting in potential comorbidity effects. By combining information on cellular interactions, disease-gene associations, and population-level disease patterns extracted from Medicare data, we find statistically significant correlations between the underlying structure of cellular networks and disease comorbidity patterns in the human population. Our results indicate that such a combination of population-level data and cellular network information could help build novel hypotheses about disease mechanisms.

AB Mutational heterogeneity represents one of the greatest barriers impeding the progress toward the clinic of gene therapies for many dominantly inherited disorders. A general strategy of gene suppression in conjunction with replacement has been proposed to overcome this mutational heterogeneity. In the current study, various aspects of this strategy are explored for a dominant form of the retinal degeneration, retinitis pigmentosa (RP), caused by mutations in the rhodopsin gene (RHO-adRP). While >200 mutations have been identified in rhodopsin ( RHO), in principle, suppression and replacement may be employed to provide a single mutation-independent therapeutic for this form of the disorder. In the study we demonstrate in a transgenic mouse simulating human RHO-adRP that RNA interference-based suppression, together with gene replacement utilizing the endogenous mouse gene as the replacement, provides significant benefit as evaluated by electroretinography (ERG). Moreover, this is mirrored histologically by preservation of photoreceptors. AAV-based vectors were utilized for in vivo delivery of the therapy to the target cell type, the photoreceptors. The results demonstrate that RNAi-based mutation-independent suppression and replacement can provide benefit for RHO-adRP and promote the therapeutic approach as potentially beneficial for other autosomal dominantly inherited disorders.

AB Current DNA methylation assays are limited in the flexibility and efficiency of characterizing a large number of genomic targets. We report a method to specifically capture an arbitrary subset of genomic targets for single-molecule bisulfite sequencing for digital quantification of DNA methylation at single-nucleotide resolution. A set of similar to 30,000 padlock probes was designed to assess methylation of similar to 66,000 CpG sites within 2,020 CpG islands on human chromosome 12, chromosome 20, and 34 selected regions. To investigate epigenetic differences associated with dedifferentiation, we compared methylation in three human fibroblast lines and eight human pluripotent stem cell lines. Chromosome-wide methylation patterns were similar among all lines studied, but cytosine methylation was slightly more prevalent in the pluripotent cells than in the fibroblasts. Induced pluripotent stem (iPS) cells appeared to display more methylation than embryonic stem cells. We found 288 regions methylated differently in fibroblasts and pluripotent cells. This targeted approach should be particularly useful for analyzing DNA methylation in large genomes.

AB Studies of epigenetic modifications would benefit from improved methods for high-throughput methylation profiling. We introduce two complementary approaches that use next-generation sequencing technology to detect cytosine methylation. In the first method, we designed similar to 10,000 bisulfite padlock probes to profile similar to 7,000 CpG locations distributed over the ENCODE pilot project regions and applied them to human B-lymphocytes, fibroblasts and induced pluripotent stem cells. This unbiased choice of targets takes advantage of existing expression and chromatin immunoprecipitation data and enabled us to observe a pattern of low promoter methylation and high gene-body methylation in highly expressed genes. The second method, methyl-sensitive cut counting, generated nontargeted genome-scale data for similar to 1.4 million HpaII sites in the DNA of B-lymphocytes and confirmed that gene-body methylation in highly expressed genes is a consistent phenomenon throughout the human genome. Our observations highlight the usefulness of techniques that are not inherently or intentionally biased towards particular subsets like CpG islands or promoter regions.

AB Depletion of Ca(2+) from the endoplasmic reticulum ( ER) results in activation of plasma membrane Ca(2+) entry channels. This 'store-operated' process requires translocation of a transmembrane ER Ca(2+) sensor protein, stromal interaction molecule 1 (STIM1), to sites closely apposed to Ca(2+) channels at the cell surface. However, it is not known whether a reduction in Ca(2+) stores is coupled to other signalling pathways by this mechanism. We found that lowering the concentration of free Ca(2+) in the ER, independently of the cytosolic Ca(2+) concentration, also led to recruitment of adenylyl cyclases. This resulted in enhanced cAMP accumulation and PKA activation, measured using FRET-based cAMP indicators. Translocation of STIM1 was required for efficient coupling of ER Ca(2+) depletion to adenylyl cyclase activity. We propose the existence of a pathway (store-operated cAMP signalling or SOcAMPS) in which the content of internal Ca(2+) stores is directly connected to cAMP signalling through a process that involves STIM1.

AB It has been proposed that inhibitors of an oncogene's effects on multipotent hematopoietic progenitor cell differentiation may change the properties of the leukemic stem cells and complement the clinical use of cytotoxic drugs. Using zebrafish, we developed a robust in vivo hematopoietic differentiation assay that reflects the activity of the oncogene AML1-ETO. Screening for modifiers of AML1-ETO-mediated hematopoietic dysregulation uncovered unexpected roles of COX-2- and beta-catenin-dependent pathways in AML1-ETO function. This approach may open doors for developing therapeutics targeting oncogene function within leukemic stem cells.

AB QT interval duration, reflecting myocardial repolarization on the electrocardiogram, is a heritable risk factor for sudden cardiac death and drug-induced arrhythmias. We conducted a meta-analysis of three genome-wide association studies in 13,685 individuals of European ancestry from the Framingham Heart Study, the Rotterdam Study and the Cardiovascular Health Study, as part of the QTGEN consortium. We observed associations at P < 5 x 10(-8) with variants in NOS1AP, KCNQ1, KCNE1, KCNH2 and SCN5A, known to be involved in myocardial repolarization and mendelian long-QT syndromes. Associations were found at five newly identified loci, including 16q21 near NDRG4 and GINS3, 6q22 near PLN, 1p36 near RNF207, 16p13 near LITAF and 17q12 near LIG3 and RFFL. Collectively, the 14 independent variants at these 10 loci explain 5.4-6.5% of the variation in QT interval. These results, together with an accompanying paper, offer insights into myocardial repolarization and suggest candidate genes that could predispose to sudden cardiac death and drug-induced arrhythmias.

AB Polycythemia vera, essential thrombocythemia and primary myelofibrosis are myeloproliferative neoplasms (MPN) characterized by multilineage clonal hematopoiesis(1-5). Given that the identical somatic activating mutation in the JAK2 tyrosine kinase gene (JAK2(V617F)) is observed in most individuals with polycythemia vera, essential thrombocythemia and primary myelofibrosis(6-10), there likely are additional genetic events that contribute to the pathogenesis of these phenotypically distinct disorders. Moreover, family members of individuals with MPN are at higher risk for the development of MPN, consistent with the existence of MPN predisposition loci(11). We hypothesized that germline variation contributes to MPN predisposition and phenotypic pleiotropy. Genome-wide analysis identified an allele in the JAK2 locus (rs10974944) that predisposes to the development of JAK2(V617F)-positive MPN, as well as three previously unknown MPN modifier loci. We found that JAK2(V617F) is preferentially acquired in cis with the predisposition allele. These data suggest that germline variation is an important contributor to MPN phenotype and predisposition.

INFLAMMATION
AB Juvenile hemochromatosis is an iron-overload disorder caused by mutations in the genes encoding the major iron regulatory hormone hepcidin ( HAMP) 1 and hemojuvelin (HFE2)(2). We have previously shown that hemojuvelin is a co-receptor for bone morphogenetic proteins (BMPs) and that BMP signals regulate hepcidin expression and iron metabolism(3,4). However, the endogenous BMP regulator(s) of hepcidin in vivo is unknown. Here we show that compared with soluble hemojuvelin (HJV.Fc), the homologous DRAGON.Fc is a more potent inhibitor of BMP2 or BMP4 but a less potent inhibitor of BMP6 in vitro. In vivo, HJV.Fc or a neutralizing antibody to BMP6 inhibits hepcidin expression and increases serum iron, whereas DRAGON.Fc has no effect. Notably, Bmp6-null mice have a phenotype resembling hereditary hemochromatosis, with reduced hepcidin expression and tissue iron overload. Finally, we demonstrate a physical interaction between HJV.Fc and BMP6, and we show that BMP6 increases hepcidin expression and reduces serum iron in mice. These data support a key role for BMP6 as a ligand for hemojuvelin and an endogenous regulator of hepcidin expression and iron metabolism in vivo.

AB Manipulations of activity in one retina can profoundly affect binocular connections in the visual cortex. Retinal activity is relayed to the cortex by the dorsal lateral geniculate nucleus (dLGN). We compared the qualities and amount of activity in the dLGN following monocular eyelid closure and monocular retinal inactivation in awake mice. Our findings substantially alter the interpretation of previous studies and define the afferent activity patterns that trigger cortical plasticity.

AB Sonic Hedgehog (Shh) has dual roles in vertebrate development, promoting progenitor cell proliferation and inducing tissue patterning. We found that the mitogenic and patterning functions of Shh can be uncoupled from one another. Using a genetic approach to selectively inhibit Shh-proteoglycan interactions in a mouse model, we found that binding of Shh to proteoglycans was required for proliferation of neural stem/precursor cells, but not for tissue patterning. Shh-proteoglycan interactions regulated both spatial and temporal features of Shh signaling. Proteoglycans localized Shh to specialized mitogenic niches and also acted at the single-cell level to regulate the duration of Shh signaling, thereby promoting a gene expression program that is important for cell division. Because activation of the Shh pathway is a feature of diverse human cancers, selective stimulation of proliferation by Shh-proteoglycan interactions may also figure prominently in neoplastic growth.

AB Synaptic adhesion molecules regulate multiple steps of synapse formation and maturation. The great diversity of neuronal synapses predicts the presence of a large number of adhesion molecules that control synapse formation through trans-synaptic and heterophilic adhesion. We identified a previously unknown trans-synaptic interaction between netrin-G ligand-3 (NGL-3), a postsynaptic density (PSD) 95-interacting postsynaptic adhesion molecule, and leukocyte common antigen-related (LAR), a receptor protein tyrosine phosphatase. NGL-3 and LAR expressed in heterologous cells induced pre-and postsynaptic differentiation in contacting axons and dendrites of cocultured rat hippocampal neurons, respectively. Neuronal overexpression of NGL-3 increased presynaptic contacts on dendrites of transfected neurons. Direct aggregation of NGL-3 on dendrites induced coclustering of excitatory postsynaptic proteins. Knockdown of NGL-3 reduced the number and function of excitatory synapses. Competitive inhibition by soluble LAR reduced NGL-3-induced presynaptic differentiation. These results suggest that the trans-synaptic adhesion between NGL-3 and LAR regulates excitatory synapse formation in a bidirectional manner.

AB Transitions between epithelial and mesenchymal states have crucial roles in embryonic development. Emerging data suggest a role for these processes in regulating cellular plasticity in normal adult tissues and in tumours, where they can generate multiple, distinct cellular subpopulations contributing to intratumoural heterogeneity. Some of these subpopulations may exhibit more differentiated features, whereas others have characteristics of stem cells. Owing to the importance of these tumour-associated phenotypes in metastasis and cancer-related mortality, targeting the products of such cellular plasticity is an attractive but challenging approach that is likely to lead to improved clinical management of cancer patients.

AB Clinical consequences of heart failure are fatigue, dyspnea, and progressive impairment of exercise tolerance. regular exercise training is associated with health-improving effects. in patients with stable heart failure, exercise training can relieve symptoms, improve exercise capacity and quality of life, as well as reduce hospitalization and, to some extent, risk of mortality. Progressive exercise training is associated with pulmonary, cardiovascular, and skeletal muscle metabolic adaptations that increase oxygen delivery and energy production. This review focuses on current knowledge of mechanisms by which progressive and moderate exercise training can have sustained beneficial effects on patients with heart failure.

AB Most brain tumors oversecrete vascular endothelial growth factor (VEGF), which leads to an abnormally permeable tumor vasculature. This hyperpermeability allows fluid to leak from the intravascular space into the brain parenchyma, which causes vasogenic cerebral edema and increased interstitial fluid pressure. increased interstitial fluid pressure has an important role in treatment resistance by contributing to tumor hypoxia and preventing adequate tumor penetration of chemotherapy agents. in addition, edema and the corticosteroids needed to control cerebral edema cause significant morbidity and mortality. Agents that block the VEGF pathway are able to decrease vascular permeability and, thus, cerebral edema, by restoring the abnormal tumor vasculature to a more normal state. Decreasing cerebral edema minimizes the adverse effects of corticosteroids and could improve clinical outcomes. Anti-VEGF agents might also be useful in other cancer-related conditions that increase vascular permeability, such as malignant pleural effusions or ascites.

AB Commercial antibodies are used widely to quantify and localize the alpha 1-adrenergic receptor (AR) subtypes, alpha 1A, alpha 1B, and alpha 1D. We tested ten antibodies, from abcam and Santa Cruz, using western blot with heart and brain tissue from wild-type (WT) mice and mice with systemic knockout (KO) of one or all three subtypes. We found that none of the antibodies detected a band in WT that was absent in the appropriate KO or in the KO that was null for all alpha 1-ARs (ABDKO). We conclude that the antibodies we tested are not specific for alpha 1-ARs. These results raise caution with prior studies using these reagents. For now, competition radioligand binding is the only reliable approach to quantify the alpha 1-AR subtype proteins. Receptor protein localization remains a challenge.

MALIGNANT GLIOMA
AB Glioblastoma multiforme (GBM) arises from genetic and signaling abnormalities in components of signal transduction pathways involved in proliferation, survival, and the cell cycle axis. Studies to date with single-agent targeted molecular therapy have revealed only modest effects in attenuating the growth of these tumors, suggesting that targeting multiple aberrant pathways may be more beneficial. Heat-shock protein 90 (HSP90) is a molecular chaperone that is involved in the conformational maturation of a defined group of client proteins, many of which are deregulated in GBM. 17-allylamino-17-demethoxygeldanamycin (17-AAG) is a well-characterized HSP90 inhibitor that should be able to target many of the aberrant signal transduction pathways in GBM. We assessed the ability of 17-AAG to inhibit the growth of glioma cell lines and glioma stem cells both in vitro and in vivo and assessed its ability to synergize with radiation and/or temozolomide, the standard therapies for GBM. Our results reveal that 17-AAG is able to inhibit the growth of both human glioma cell lines and glioma stem cells in vitro and is able to target the appropriate proteins within these cells. In addition, 17-AAG can inhibit the growth of intracranial tumors and can synergize with radiation both in tissue culture and in intracranial tumors. This compound was not found to synergize with temozolomide in any of our models of gliomas. Our results suggest that HSP90 inhibitors like 17-AAG may have therapeutic potential in GBM, either as a single agent or in combination with radiation.

AB The introduction of methotrexate (MTX)-based chemotherapy has improved median survival for patients with primary CNS lymphoma (PCNSL). Older age is a negative prognostic marker in patients with PCNSL and may increase the likelihood of MTX toxicity. We studied the response and adverse effects of intravenous high-dose MTX in patients who were 70 or more years of age at the time of diagnosis. We identified 31 patients at our institution diagnosed with PCNSL at age >= 70 years (median, 74 years) who were treated with high-dose MTX (3.5-8 g/m(2)) as initial therapy from 1992 through 2006. The best response to MTX was determined by contrast-enhanced MRI. Toxicity was analyzed by chart review. These 31 patients received a total of 303 cycles of MTX (median, eight cycles per patient). Overall, 87.9% of the cycles required dose reduction because of impaired creatinine clearance. In 30 evaluable patients, the overall radiographic response rate was 96.7%, with 18 complete responses (60%) and 11 partial responses (36.7%). Progression-free survival and overall survival were 7.1 months and 37 months, respectively. Grade I-IV toxicities were observed in 27 of 31 patients and included gastrointestinal disturbances in 58% (3.2% grade III), hematological complications in 80.6% (6.5% grade III), and renal toxicity in 29% (0% grade III/IV). High-dose MTX is associated with a high proportion of radiographic responses and a low proportion of grade III/IV toxicity in patients 70 or more years of age. High-dose MTX should be considered as a feasible treatment option in elderly patients with PCNSL. Neuro-Oncology 11, 211-215, 2009 (Posted to Neuro-Oncology [serial online], Doc.

AB This study determined (a) the association between stages of Alzheimer's disease (AD) and overall gene expression change, and (b) brain regions of greatest vulnerability to transcriptional change as the disease progressed. Fifteen cerebrocortical sites and the hippocampus were examined in persons with either no cognitive impairment or neuropathology, or with only AD-associated lesions. Cases were stratified into groups of 7 19 based on the degree of cognitive impairment (clinical dementia rating scale, CDR); neurofibrillary tangle distribution and severity (Braak staging) or density of cerebrocortical neuritic plaque (NP; grouping by NP density). Transcriptional change was assessed by Affymetrix U 133 mRNA microarray analysis. The results suggested that (a) gene expression changes in the temporal and prefrontal cortices tire more closely related to disease severity than other regions examined; (b) more genes are down-regulated at,my given disease severity stage than up-regulated; (c) the degree of gene expression change in a given regions depends oil the disease severity classification scheme used; and (d) the classification of cases by CDR provides a more orderly gradient of gene expression change in most brain regions than Braak staging or NP grouping.

AB Objective: To determine whether variants in the estrogen receptors 1 (alpha) and 2 (beta) (ESR1 and ESR2) genes are associated with cognitive impairment in non-demented elderly men and women.
Background: Several single nucleotide polymorphisms (SNPs) on ESR1 and ESR2 genes have been associated with a range of hormone sensitive diseases such as breast cancer and osteoporosis. Genetic variations in ESR may also influence cognitive aging but are less studied, especially among men.
Methods: We studied 2527 participants enrolled in an ongoing prospective study of community-dwelling elders. Four SNPs from ESR1 and four from ESR2 were analyzed. We measured cognitive function with the Modified Mini-Mental Status Examination (3MS) at baseline and biannually cognitive impairment was defined as it decline of live or more points over 4 years. We calculated odds of developing cognitive impairment across SNPS using gender-stratified logistic regression and adjusted analyses for age, education, baseline 3MS score and in addition for race.
Results: One thousand three hundred and forty-three women (mean age 73.4) and 1184 men (mean age 73.7) comprised Our cohort. Among women, after multivariate adjustment, two of the ESR1 SNPs (rs8179176, rs9340799) and two of the ESR2 SNPs (rs1256065, rs1256030) were associated with likelihood of developing cognitive impairment., although the association for rs8179176 was of trend level significance. In men, one of the ESR1 SNPs (rs729524) and two of the ESR2 (rs1255998, rs1256030) were associated with cognitive impairment. Further adjustment for race attenuated the results somewhat. There was no association between any ESR SNP and level of bioavailable estradiol but testosterone level did vary among two of the SNPs (p < 0.05).
Conclusion: We found that among non-demented Community elders, several SNPs in the ESR1 and ESR2 genes were associated with risk of developing cognitive impairment. These findings suggest that estrogen receptor genetic variants may play it role in cognitive aging. (C) 2007 Elsevier Inc. All rights reserved.

AB DYT1 dystonia is caused by a deletion in a glutamic acid residue in the C-terminus of the protein torsinA, whose function is still largely unknown. Alterations in GABAergic signaling have been involved in the pathogenesis of dystonia. We recorded GABA- and glutamate-mediated synaptic currents from a striatal slice preparation obtained from a mouse model of DYT1 dystonia. In medium spiny neurons (MSNs) from mice expressing human mutant torsinA (hMT), we observed a significantly higher frequency, but not amplitude, of GABAergic spontaneous inhibitory postsynaptic currents (sIPSCs) and miniature currents (mIPSCs), whereas glutamate-dependent spontaneous excitatory synaptic currents (sEPSCs) were normal. No alterations were found in mice overexpressing normal human torsinA (hWT). To identify the possible sources of the increased GABAergic tone, we recorded GABAergic Fast-Spiking (FS) interneurons that exert a feed-forward inhibition on MSNs. However, both sEPSC and slPSC recorded from hMT FS interneurons were comparable to hWT and non-transgenic (NT) mice. In physiological conditions, dopamine (DA) D2 receptor act presynaptically to reduce striatal GABA release. Of note, application of the D2-like receptor agonist quinpirole failed to reduce the frequency of sIPSCs in MSNs from hMT as compared to hWT and NT mice. Likewise, the inhibitory effect of quinpirole was lost on evoked IPSCs both in MSNs and FS interneurons from hMT mice. Our findings demonstrate a disinhibition of striatal GABAergic synaptic activity, that can be at least partially attributed to a D2 DA receptor dysfunction. (C) 2009 Elsevier Inc.

AB Fluorescent molecular tomographic (FMT) imaging can noninvasively monitor molecular function in living animals using specific fluorescent probes. However, macroscopic imaging methods such as FMT generally exhibit low anatomical details. To overcome this, we report a quantitative technique to image both structure and function by combining FMT and magnetic resonance (MR) imaging. We show that FMT-MR imaging can produce three-dimensional, multimodal images of living mouse brains allowing for serial monitoring of tumor morphology and protease activity. Combined FMT-MR tumor imaging provides a unique in vivo diagnostic parameter, protease activity concentration (PAC), which reflects histological changes in tumors and is significantly altered by systemic chemotherapy. Alterations in this diagnostic parameter are detectable early after chemotherapy and correlate with subsequent tumor growth, predicting tumor response to chemotherapy. Our results reveal that combined FMT-MR imaging of fluorescent molecular probes could be valuable for brain tumor drug development and other neurological and somatic imaging applications.

AB MR diffusion tensor imaging (DTI) can measure and visualize organization of white matter fibre tracts in vivo. DTI is a relatively new imaging technique, and new tools developed for quantifying fibre tracts require evaluation. The purpose of this study was to compare the reliability of a novel clustering approach with a multiple region of interest (MROI) approach in both healthy and disease (schizophrenia) populations.
DTI images were acquired in 20 participants (n = 10 patients with schizophrenia: 56 +/- 15 years; n = 10 controls: 51 +/- 20 years) (1.5 T GE system) with diffusion gradients applied in 23 non-collinear directions, repeated three times. Whole brain seeding and creation of fibre tracts were then performed. Interrater reliability of the clustering approach, and the MROI approach, were each evaluated and the methods compared.
There was high spatial (voxel-based) agreement within and between the clustering and MROI methods. Fractional anisotropy, trace, and radial and axial diffusivity values showed high intraclass correlation (p<0.001 for all tracts) for each approach. Differences in scalar indices of diffusion between the clustering and MROI approach were minimal.
The excellent interrater reliability of the clustering method and high agreement with the MROI method, quantitatively and spatially, indicates that the clustering method can be used with confidence. The clustering method avoids biases of ROI drawing and placement, and, not limited by a priori predictions, may be a more robust and efficient way to identify and measure white matter tracts of interest.

AB While the ability of near-infrared spectroscopy (NIRS) to measure cerebral hemodynamic evoked responses (slow optical signal) is well established, its ability to measure non-invasively the 'fast optical signal' is still controversial. Here, we aim to determine the feasibility of performing NIRS measurements of the 'fast optical signal' or Event-Related Optical Signals (EROS) under optimal experimental conditions in awake behaving macaque monkeys. These monkeys were implanted with a 'recording well' to expose the dura above the primary visual cortex (V1). A custom-made optical probe was inserted and fixed into the well. The close proximity of the probe to the brain maximized the sensitivity to changes in optical properties in the cortex. Motion artifacts were minimized by physical restraint of the head. Full-field contrast-reversing checkerboard stimuli were presented to monkeys trained to perform a visual fixation task. In separate sessions, two NIRS systems (CW4 and ISS FD oximeter), which previously showed the ability to measure the fast signal in human, were used. In some sessions EEG was acquired simultaneously with the optical signal. The increased sensitivity to cortical optical changes with our experimental setup was quantified with 3D Monte Carlo simulations on a segmented MRI monkey head. Averages of thousands of stimuli in the same animal, or grand averages across the two animals and across repeated sessions, did not lead to detection of the fast optical signal using either amplitude or phase of the optical signal. Hemodynamic responses and visual evoked potentials were instead always detected with single trials or averages of a few stimuli. Based on these negative results, despite the optimal experimental conditions, we doubt the usefulness of non-invasive fast optical signal measurements with NIRS. (c) 2008 Elsevier Inc.

AB OBJECTIVE: Hemorrhage is an infrequent but potentially devastating complication of deep brain stimulation (DBS) surgery. We examined the factors associated with hemorrhage after DBS surgery and evaluated a modified microelectrode design that may improve the safety of this procedure.
METHODS: All microelectrode-guided DBS procedures performed at our institution between January 2000 and March 2008 were included in this study. A new microelectrode design with decreased diameter was introduced in May 2004, and data from the 2 types of electrodes were compared.
RESULTS: We examined 246 microelectrode-guided lead implantations in 130 patients. Postoperative imaging revealed 7 hemorrhages (2.8%). Five of the 7 (2.0%) resulted in focal neurological deficits, all of which resolved within 1 month with the exception of I patient lost to follow-up. The new microelectrode design significantly decreased the number of hemorrhages (P = 0.04). A surgical trajectory traversing the ventricle also contributed significantly to the overall hemorrhage rate (P = 0.02) and specifically to the intraventricular hemorrhage rate (P = 0.01). In addition, the new microelectrode design significantly decreased the rate of intraventricular hemorrhage, given a ventricular penetration (P = 0.01). The mean age of patients with hemorrhage was significantly higher than that of patients without hemorrhage (P = 0.02). Hypertension, sex, and number of microelectrodes passed did not significantly contribute to hemorrhage rates in our population.
CONCLUSION: The rate of complications after DBS surgery is not uniformly distributed across all cases. In particular, the rates of hemorrhage were increased in older patients. Importantly, transventricular electrode trajectories appeared to increase the risk of hemorrhage. A new microelectrode design minimizing the volume of brain parenchyma penetrated during microelectrode recording leads to decreased rates of hemorrhage, particularly if the ventricles are breached.

AB Transplantation of neural cells for the treatment of neurologic disorders has garnered much attention and considerable enthusiasm from patients and physicians alike. Cell-based therapies have been proposed for a wide range of central nervous system pathologies ranging from stroke and trauma to demyelinating disorders and neurodegenerative diseases. Notably, cell transplantation for Parkinson disease (PD) has become even more attractive with the rapid advances in derivation of dopaminergic neurons from human embryonic stem cells. This article briefly reviews some of the relevant issues regarding the transplantation of cells for treatment of PD and hypothesizes how interventional MRI may be useful to optimize the surgical delivery of cells for PD and other central nervous system disorders.

AB Physical approaches for the treatment of epilepsy currently under study or development include electrical or magnetic brain stimulators and cooling devices, each of which may be implanted or applied externally. Some devices may stimulate peripheral structures, whereas others may be implanted directly into the brain. Stimulation may be delivered chronically, intermittently, or in response to either manual activation or computer-based detection of events of interest. Physical approaches may therefore ultimately be appropriate for seizure prophylaxis by causing a modification of the underlying substrate, presumably with a reduction in the intrinsic excitability of cerebral structures, or for seizure termination, by interfering with the spontaneous discharge of pathological neuronal networks. Clinical trials of device-based therapies are difficult due to ethical issues surrounding device implantation, problems with blinding, potential carryover effects that may occur in crossover designs if substrate modification occurs, and subject heterogeneity. Unresolved issues in the development of physical treatments include optimization of stimulation parameters, identification of the optimal volume of brain to be stimulated, development of adequate power supplies to stimulate the necessary areas, and a determination that stimulation itself does not promote epileptogenesis or adverse long-term effects on normal brain function.

AB A high percentage of patients with temporal lobe epilepsy (TLE) are refractory to conventional pharmacotherapy. The progressive neurodegenerative processes associated with a lifetime of uncontrolled seizures mandate the development of alternative approaches to treat this disease. Transplantation of inhibitory cells has been suggested as a potential therapeutic strategy to achieve seizure suppression in humans with intractable TLE. Preclinical investigations over 20 years have demonstrated that multiple cell types from several sources can produce anticonvulsant, and antiepileptogenic, effects in animal models of TLE. Transplanting GABA-producing cells, in particular, has been shown to reduce seizures in several well-established models. This review addresses experimentation using different sources of transplantable GABAergic cells, highlighting progress with fetal tissue, neural cell lines, and stem cells. Regardless of the source of the GABAergic cells used in seizure studies, common challenges have emerged. Several variables influence the anticonvulsant potential of GABA-producing cells. For example, tissue availability, graft survival, immunogenicity, tumorigenicity, and varying levels of cell migration, differentiation, and integration into functional circuits and the microenvironment provided by sclerotic tissue all contribute to the efficacy of transplanted cells. The challenge of understanding how all of these variables work in concert, in a disease process that has no well-established etiology, suggests that there is still much basic research to be done before rational cell-based therapies can be developed for TLE.

PATHWAY
AB Both Fanconi anemia (FA) and telomere dysfunction are associated with chromosome instability and an increased risk of cancer. Because of these similarities, we have investigated whether there is a relationship between the FA protein, FANCD2 and telomeres. We find that FANCD2 nuclear foci colocalize with telomeres and PML bodies in immortalized telomerase-negative cells. These cells maintain telomeres by alternative lengthening of telomeres (ALT). In contrast, FANCD2 does not colocalize with telomeres or PML bodies in cells which express telomerase. Using a siRNA approach we find that FANCA and FANCL, which are components of the FA nuclear core complex, regulate FANCD2 monoubiquitination and the telomeric localization of FANCD2 in ALT cells. Transient depletion of FANCD2, or FANCA, results in a dramatic loss of detectable telomeres in ALT cells but not in telomerase-expressing cells. Furthermore, telomere loss following depletion of these proteins in ALT cells is associated with decreased homologous recombination between telomeres (T-SCE). Thus, the FA pathway has a novel function in ALT telomere maintenance related to DNA repair. ALT telomere maintenance is therefore one mechanism by which monoubiquitinated FANCD2 may promote genetic stability.
