AB Obsessive-compulsive disorder (OCD) influences not only patients but also family members. Although the construct of family accommodation has received attention in OCD literature, no measures of overall family functioning are currently available. The OCD Family Functioning (OFF) Scale was developed to explore the context, extent, and perspectives of functional impairment in families affected by OCD. It is a three-part, self-report measure capturing independent perspectives of patients and relatives. A total of 400 subjects were enrolled between 2008 and 2010 from specialized OCD clinics and OCD research studies. Psychometric properties of this scale were examined including internal consistency, test-retest reliability, convergent and divergent validity, and exploratory factor analyses. Both patient and relative versions of the OFF Scale demonstrated excellent internal consistency (Cronbach's alpha coefficient = 0.96). The test-retest reliability was also adequate (ICC = 0.80). Factor analyses determined that the OFF Scale comprises a family functioning impairment factor and four OCD symptom factors that were consistent with previously reported OCD symptom dimension studies. The OFF Scale demonstrated excellent convergent validity with the Family Accommodation Scale and the Work and Social Adjustment Scale. Information gathered regarding emotional impact and family role-specific impairment was novel and not captured by other examined scales. The OFF Scale is a reliable and valid instrument for the clinical and research assessment of family functioning in pediatric and adult OCD. This will facilitate the exploration of family functioning impairment as a potential risk factor, as a moderator and as a treatment outcome measure in OCD.

ID MARITAL SATISFACTION; QUALITY
AB Couples presenting for treatment of relationship distress often experience additional problems, including individual psychopathology and intimate partner violence (IPV). Both issues are associated with current and future poor relationship functioning in nontreatment samples, but relatively little is understood about their association with initial presentation and outcomes in couple therapy. The current study examined these associations in a sample of 177 heterosexual couples who received therapy at two Veteran's Affairs clinics. Unlike most studies of couple therapy outcomes, couples were not excluded from treatment specifically because of high levels of psychopathology or IPV. Results of Actor Partner Interdependence Model (APIM) analyses revealed actor and partner effects of depression, actor effects of anxiety, and partner effects of IPV on initial relationship satisfaction, such that greater coexisting difficulties were associated with poorer initial satisfaction. However, improvement in relationship satisfaction over the course of therapy was not associated with psychopathology, and, contrary to hypothesis, was positively associated with men's IPV prior to treatment, even when initial level of satisfaction was controlled. The results suggest that coexisting symptoms of psychopathology or IPV may not necessarily interfere with therapy outcomes and, indeed, therapy may have positive effects for couples with these problems.

TI Incidence of Fanconi Anemia in Children with Congenital Thumb Anomalies
Referred for Diepoxybutane Testing
SO JOURNAL OF HAND SURGERY-AMERICAN VOLUME
LA English
DT Article
DE Congenital; Fanconi anemia; radius; hypoplasia; thumb
ID BONE-MARROW FAILURE; REGISTRY; DIAGNOSIS; CANCER; RISKS
AB Purpose Fanconi anemia (FA) is a rare genetic disorder of DNA repair that with near uniformity leads to bone marrow failure and resulting morbidity and mortality. Approximately 50% of FA patients are born with anomalies of the thumb or thumb and radius, and it has been recommended that all patients born with thumb anomalies undergo testing. However, the risk of FA in this population is unknown. We determined the incidence of FA in children with congenital thumb anomalies referred for FA testing and characterized those who tested positive.
Methods We queried our database for patients who presented with congenital thumb anomalies and who underwent diepoxybutane (DEB) testing for FA between 1999 and 2008 at Children's Hospital Boston and the Dana-Farber Cancer Institute.
Results During this time period, 543 congenital thumb anomaly patients (235 with thumb hypoplasia) presented to our institution. A total of 81 patients with thumb abnormalities underwent DEB testing. Six patients (7% of those tested; 1% of the total; 3% of thumb hypoplasia patients) had a positive DEB test consistent with the diagnosis of FA; all had other non-upper-extremity anomalies associated with FA. Of 6 FA patients, 5 had bilateral involvement; all had some degree of thumb hypoplasia (3 also had radial dysplasia). Mean age at testing was 2.6 years (SD 4.3). Most of the patients tested had multiple physical anomalies (n = 66). The anomaly distribution was: thumb hypoplasia and radial dysplasia (n = 29), thumb hypoplasia (n = 26), radial polydactyly (n = 12), radial polydactyly and radial dysplasia (n = 1), and proximally placed thumb and radial dysplasia (n = 1). Twelve patients had other thumb anomalies.
Conclusions Although the incidence of FA in patients with thumb anomalies may be low, patients with thumb hypoplasia and other physical findings associated with FA, specifically cafe au lait spots and short stature, appear to have an increased risk of FA. Because hand surgeons see these patients early in life, they have the opportunity to refer these patients for FA testing to initiate early education, family genetic counseling, and treatment if warranted.

AB Ligands of the thiazolidinedione (TZD) class of compounds, pioglitazone (Actos (TM)) and rosiglitazone (Avandia (TM)) are currently approved for treatment of type 2 diabetes and are known to bind to the PPAR-gamma gamma nuclear receptor subtype. Recent evidence suggesting PPAR-gamma independent action of the TZDs led to the discovery of a novel integral outer mitochondrial membrane protein, mitoNEET. In spite of the several reported X-ray crystal structures of the unbound form cif mitoNEET, the location and nature of the mitoNEET ligand binding sites (LBS) remain unknown. In this study, a molecular blind docking (BD) method was used to discover potential mitoNEET LBS and novel ligands, utilizing the program AutoDock Vina (v 1.0.2). Validation of BD was performed on the PPAR-gamma receptor (PDB ID: 1ZGY) with the test compound rosiglitazone, demonstrating that the binding conformation of rosiglitazone determined by AutoDock Vina matches well with that of the cocrystallized ligand (root mean square deviation of the heavy atoms 1.45 angstrom). The locations and a general ligand binding interaction model for the LBS were determined, leading to the discovery of novel mitoNEET ligands. An in vitro fluorescence binding assay utilizing purified recombinant mitoNEET protein was used to determine the binding affinity of a predicted mitoNEET ligand, and the data obtained is in good agreement with AutoDock Vina results. The discovery of potential mitoNEET ligand binding sites and novel ligands, opens up the possibility for detailed structural studies of mitoNEET-ligand complexes, as well as rational design of novel ligands specifically targeted for mitoNEET.

AB Teaching advanced communication skills requires educators who are not only excellent communicators themselves but have the ability to deconstruct the components of the interaction and develop a cognitive approach that can be used across a variety of learners, diverse content, and under different time constraints while helping the learner develop the skill of self-reflection in a 'safe' and effective learning environment. The use of role-play in small groups is an important method to help learners cultivate the skills required to engage in nuanced, often difficult conversations with seriously ill patients. To be effective, educators utilizing role-play must help learners set realistic goals and know when and how to provide feedback to the learners in a way that allows a deepening of skills and a promotion of self-awareness. The challenge is to do this in a manner that does not cause too much anxiety for the learner. In this article we outline an approach to teaching communication skills to advanced learners through the use of different types of role-play, feedback, and debriefing.

AB Despite a general consensus that dimensional models are superior to the categorical representations of personality disorders in DSM-IV, proposals for how to depict personality pathology dimensions vary substantially. One important question involves how to separate clinical severity from the style of expression through which personality pathology manifests. This study empirically distinguished stylistic elements of personality pathology symptoms from the overall severity of personality disorder in a large, longitudinally assessed clinical sample (N = 605). Data suggest that generalized severity is the most important single predictor of current and prospective dysfunction, but that stylistic elements also indicate specific areas of difficulty. Normative personality traits tend to relate to the general propensity for personality pathology, but not stylistic elements of personality disorders. Overall, findings support a three-stage diagnostic strategy involving a global rating of personality disorder severity, ratings of parsimonious and discriminant valid stylistic elements of personality disorder, and ratings of normative personality traits.

AB Post-traumatic stress disorder (PTSD) is associated with elevated catecholamines and increased sympathetic arousal. However, it is unknown whether this condition is a pre-existing vulnerability factor for PTSD or an acquired result of either trauma exposure or the development of FTSD symptoms. We sought to examine if salivary 3-methoxy-4-hydroxy-phenylglycol (MHPG) in response to a laboratory stressor prior to critical incident exposure predicts the development of PTSD symptoms and if early childhood trauma influences this relationship. In a prospective cohort study, 349 urban police officers were assessed during academy training (baseline) and 243 were reassessed 12 months after the start of active duty (follow-up). At baseline, participants observed a video consisting of police critical incidents. Salivary MHPG was measured before and immediately after the challenge, and after 20 min recovery. At follow-up, peritraumatic distress and PTSD symptoms were assessed in relationship to the worst critical incident during the past year. Participants with childhood trauma showed a trend towards higher MHPG increase to the challenge. Higher MHPG levels after 20 min recovery were associated with both higher levels of peritraumatic distress and PTSD symptoms at follow-up. In a path analysis, elevated MHPG levels predicted higher peritraumatic distress which in turn predicted higher levels of PTSD symptoms while the direct effect of elevated MHPG levels on PTSD symptoms was no longer significant. Prolonged elevation of salivary MHPG in response to a laboratory stressor marks a predisposition to experience higher levels of peritraumatic distress and subsequently more PTSD symptoms following critical incident exposure.

AB Borderline Personality Disorder (BPD) is a serious illness characterized by emotional dysregulation, impulsivity, and impaired interpersonal relationships. Prior work shows the anterior cingulate gyrus (ACG)-a region primarily involved in assessing the salience of emotional information and regulating emotional responses-is smaller in adults with BPD. We tested the hypothesis that, similar to adults, adolescents with BPD would have reduced Brodmann area (BA)-24 volume. Thirteen adolescent inpatients with co-morbid BPD and Major Depressive Disorder (MDD) and 13 matched healthy controls received 3T-MRI scans. Using a cytoarchitecturally-derived approach measuring gray and white matter volume, we observed a Group x Cingulate BA (25,24,31,23,29) x Matter (gray, white) type interaction indicating the BPD/MDD adolescents had smaller BA24 volume in gray but not white matter. Greater number of suicide attempts and BPD symptom severity measured by the Diagnostic Interview for BPD-revised (DIB-R) total score but not depressive symptoms measured by the Beck Depression Inventory (BDI) was associated with smaller BA24 volume. Our preliminary findings suggest that BPD-related abnormalities in BA24 volume may occur early in the developmental course of BPD with MDD. Future studies examining samples of MDD patients with and without BPD co-morbidity will be needed to clarify whether BA24 volume reductions are specific to BPD. Published by Elsevier Ltd.

AB Background Although prostate cancer is commonly diagnosed, few risk factors for high-grade prostate cancer are known and few prevention strategies exist. Statins have been proposed as a possible treatment to prevent prostate cancer.
Methods Using electronic and administrative files from the Veterans Affairs New England Healthcare System, we identified 55 875 men taking either a statin or antihypertensive medication. We used age-and multivariable-adjusted Cox proportional hazard models to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for prostate cancer incidence among patients taking statins (n = 41 078) compared with patients taking antihypertensive medications (n = 14 797). We performed similar analyses for all lipid parameters including total cholesterol examining each lipid parameter as a continuous variable and by quartiles. All statistical tests were two-sided.
Results Compared with men taking an antihypertensive medication, statin users were 31% less likely (HR = 0.69, 95% CI = 0.52 to 0.90) to be diagnosed with prostate cancer. Furthermore, statin users were 14% less likely (HR = 0.86, 95% CI = 0.62 to 1.20) to be diagnosed with low-grade prostate cancer and 60% less likely (HR = 0.40, 95% CI = 0.24 to 0.65) to be diagnosed with high-grade prostate cancer compared with antihypertensive medication users. Increased levels of total cholesterol were also associated with both total (HR = 1.02, 95% CI = 1.00 to 1.05) and high-grade (HR = 1.06, 95% CI = 1.02 to 1.10) prostate cancer incidence but not with low-grade prostate cancer incidence (HR = 1.01, 95% CI = 0.98 to 1.04).
Conclusions Statin use is associated with statistically significantly reduced risk for total and high-grade prostate cancer, and increased levels of serum cholesterol are associated with higher risk for total and high-grade prostate cancer. These findings indicate that clinical trials of statins for prostate cancer prevention are warranted.

AB Background: The decision-making processes used for out-of-hospital trauma triage and hospital selection in regionalized trauma systems remain poorly understood. The objective of this study was to assess the process of field triage decision making in an established trauma system.
Methods: We used a mixed methods approach, including emergency medical services (EMS) records to quantify triage decisions and reasons for hospital selection in a population-based, injury cohort (2006-2008), plus a focused ethnography to understand EMS cognitive reasoning in making triage decisions. The study included 10 EMS agencies providing service to a four-county regional trauma system with three trauma centers and 13 nontrauma hospitals. For qualitative analyses, we conducted field observation and interviews with 35 EMS field providers and a round table discussion with 40 EMS management personnel to generate an empirical model of out-of-hospital decision making in trauma triage.
Results: A total of 64,190 injured patients were evaluated by EMS, of whom 56,444 (88.0%) were transported to acute care hospitals and 9,637 (17.1% of transports) were field trauma activations. For nontrauma activations, patient/family preference and proximity accounted for 78% of destination decisions. EMS provider judgment was cited in 36% of field trauma activations and was the sole criterion in 23% of trauma patients. The empirical model demonstrated that trauma triage is driven primarily by EMS provider "gut feeling" (judgment) and relies heavily on provider experience, mechanism of injury, and early visual cues at the scene.
Conclusions: Provider cognitive reasoning for field trauma triage is more heuristic than algorithmic and driven primarily by provider judgment, rather than specific triage criteria.

PERFUSION
AB Objectives: Type IV thoracoabdominal aortic aneurysm (TAAA) repair, despite low risk of spinal cord ischemia (SCI), is reported to have significant morbidity and mortality. This has led some to apply adjuncts (eg, extracorporeal circulation) used in more extensive TAAA repair or to consider alternative approaches, such as hybrid operations. We have used a consistent, simplified surgical approach to type IV TAAA, and the goal of the present study is to review experience over 2 decades with such treatment and to identify correlates of surgical morbidity.
Methods: All type IV repairs at Massachusetts General Hospital from January 1989 through September 2009 were evaluated for clinical features, technical operative details, and 30-day outcomes. Logistic regression identified predictors of morbidity. Survival was assessed using Kaplan-Meier analysis.
Results: A total of 179 patients underwent type IV repair, with elective repair in 156 (87%) and urgent in 23 (13%). The clamp-and-sew technique was used for all operations, with routine hypothermic renal perfusion. Clinical features were age 73 +/- 8 years, coronary artery disease in 89 (50%), and creatinine level > 1.8 mg/dL defining chronic renal insufficiency (CRI) in 32 (18%). Operative reconstruction in 166 (93%) consisted of one beveled proximal anastomosis incorporating the descending thoracic aorta, celiac, superior mesenteric artery, and right renal arteries origins (mean visceral clamp time, 36 +/- 12 minutes) and a side-arm graft to the left renal artery. Technical details included previous abdominal aortic aneurysm (AAA) repair in 52 (29%), operative time of 290 +/- 90 min, estimated blood loss of 2.7 +/- 1.4 L, and splenectomy in 57 (32%). The 30-day outcomes were death in 5 (2.8%), myocardial infarction in 6 (3.4%), hemodialysis in 5 (2.8%), and any degree of SCI in 4 (2.2%). Regression analysis identified a history of CRI as an independent predictor of postoperative complication or death (odds ratio, 3.4; 95% confidence interval, 1.4-8). Survival rates at 1, 5, and 10 years were 89% +/- 2%, 62% +/- 4%, and 36% +/- 5%, respectively.
Conclusions: A simplified operative approach for type IV TAAA repair is associated with favorable perioperative results. These data refute the need for surgical adjuncts commonly applied in more extensive TAAA and indicate that the hybrid operation is an illogical posture. CRI should figure prominently in clinical decision making. Long-term survival equates that observed after routine AAA repair. (J Vase Surg 2011;53:1492-8.)

AB Background: Many patients on hemodialysis do not have adequate anatomy for native arteriovenous fistulas. In these patients, synthetic conduits remain an alternative option for permanent hemodialysis access. We sought to compare the standard cuffed expanded polytetrafluoroethylene (ePTFE) graft with the bovine carotid artery (BCA) graft.
Methods: This was a prospective, randomized controlled trial that was set in an academic medical center. We enrolled 26 patients in the BCA group and 27 patients in the ePTFE group. Primary, assisted primary, and secondary patency were calculated using the Kaplan-Meier method. Complications were monitored and are reported.
Results: Although there was no significant difference in secondary patency rates, primary and assisted primary patency rates were significantly higher in BCA than in the ePTFE grafts (60.5% vs 10.1% and 60.5% vs 20.8% at I year, respectively). The BCA graft survival advantage was most profound in the upper arm grafts with significantly higher primary and assisted patency rates (P < .0001 and .0005, respectively). The total number of interventions (upper arm grafts) and total number of angioplasties (overall and upper arm) required to maintain patency were significantly fewer in the BCA group. The most common complication was graft thrombosis which occurred 0.34 +/- 0.09 times per patient year in the BCA group compared to 0.77 +/- 0.16 times per patient year in the ePTFE group, P = .01.
Conclusion: The BCA graft is an excellent option for patients on hemodialysis that are not suitable for native arteriovenous fistulas, as these grafts required fewer interventions than the ePTFE grafts to maintain patency. (J Vase Surg 2011;53:1640-8.)

AB Purpose: To investigate the feasibility of using three-dimensional surface imaging cameras as an external surrogate of tumor motion through a temporal synchronization with kV imaging.
Methods: To obtain an "x-ray on" signal from the on-board kV fluoroscopy system (XVI, Elekta), a hardware controller (Gate Controller) was interfaced between the kV fluoroscopy and Gate CT (VisionRT Ltd., London) computers. First, phantom experiments were performed using a programmable respiratory motion platform (sinusoidal motion, period = 3-5 s). The platform included a chest-wall component (A-P amplitude = 1 cm) tracked with the surface camera, while tumorlike objects translated in the superior-inferior direction were tracked using kV fluoroscopy (300 frames, frequency similar to 5.5 fps). Accuracy of tracking the chest-wall platform was assessed, and the latency of the system was characterized by performing linear regression between the peak times obtained from Gate CT and fluoroscopy. Increasing the complexity of experiments, tumor displacement curves from three patients were simulated using synchronous tumor-abdomen data (RTRT). Our approach was further validated by imaging four free-breathing lung cancer patients with simultaneous Gate CT and kV fluoroscopy for approximately 55 s. Consideration was also given to varied sizes and locations of the tracked region of interest on the patient surface.
Results: For simple sinusoidal curves, measured amplitude (peak-to-peak) was 1.005 +/- 0.003 cm, 1.013 +/- 0.003 cm, and 1.003 +/- 0.005 cm for periods of 5, 4, and 3.3 s, respectively, demonstrating an excellent agreement with the actual chest platform amplitude of 1.0 cm. Period measurements were within 0.2% of actual using the surface cameras and within 0.9% of actual value using fluoroscopy. For the sinusoidal motion, the system latency was 0.64 +/- 0.02 s. This was further validated for the simulated tumor motion from three patients (latency = 0.65 +/- 0.03 s). Five of the nine patient fractions studied showed the associations between the abdomen and tumor were equivalent or better (Pearson r = 0.93-0.98) than those observed between the diaphragm and tumor (Pearson r = 0.89-0.95). A repeat analysis of five different tracked surfaces on the same patient further demonstrated strong agreement with the diaphragm and tumor, although no improvement in association strength was observed with increased size of region of interest.
Conclusions: The feasibility of using surface imaging cameras to track the patient's abdomen as an external surrogate, while using kV imaging to track internal anatomy in synchrony, has been demonstrated. With further validation through additional patient studies to confirm these findings, gated radiation therapy treatments using surface imaging cameras as the external surrogate can be facilitated.

AB Purpose: We propose a novel approach for PET respiratory motion correction using tagged-MRI and simultaneous PET-MRI acquisitions.
Methods: We use a tagged-MRI acquisition followed by motion tracking in the phase domain to estimate the nonrigid deformation of biological tissues during breathing. In order to accurately estimate motion even in the presence of noise and susceptibility artifacts, we regularize the traditional HARP tracking strategy using a quadratic roughness penalty on neighboring displacement vectors (R-HARP). We then incorporate the motion fields estimated with R-HARP in the system matrix of an MLEM PET reconstruction algorithm formulated both for sinogram and list-mode data representations. This approach allows reconstruction of all detected coincidences in a single image while modeling the effect of motion both in the emission and the attenuation maps. At present, tagged-MRI does not allow estimation of motion in the lungs and our approach is therefore limited to motion correction in soft tissues. Since it is difficult to assess the accuracy of motion correction approaches in vivo, we evaluated the proposed approach in numerical simulations of simultaneous PET-MRI acquisitions using the NCAT phantom. We also assessed its practical feasibility in PET-MRI acquisitions of a small deformable phantom that mimics the complex deformation pattern of a lung that we imaged on a combined PET-MRI brain scanner.
Results: Simulations showed that the R-HARP tracking strategy accurately estimated realistic respiratory motion fields for different levels of noise in the tagged-MRI simulation. In simulations of tumors exhibiting increased uptake, contrast estimation was 20% more accurate with motion correction than without. Signal-to-noise ratio (SNR) was more than 100% greater when performing motion-corrected reconstruction which included all counts, compared to when reconstructing only coincidences detected in the first of eight gated frames. These results were confirmed in our proof-of-principle PET-MRI acquisitions, indicating that our motion correction strategy is accurate, practically feasible, and is therefore ready to be tested in vivo.
Conclusions: This work shows that PET motion correction using motion fields measured with tagged-MRI in simultaneous PET-MRI acquisitions can be made practical for clinical application and that doing so has the potential to remove motion blur in whole-body PET studies of the torso.

ID MOTION; RADIOTHERAPY; ERRORS
AB Purpose: To evaluate the effect of target trajectory shape on the optimal treatment margin.
Methods: Intensity-modulated radiation therapy and volumetric modulated arc therapy plans were created for three spherical targets (3, 5, and 7 cm diameter) simulated in exhalation phases, each with margins of 2, 4, 6, 8, and 10 mm to account for motion. The plans were delivered to a stationary 2D ion chamber array, and dose movies were obtained of the delivered doses. The dose movie frames were then displaced to simulate different respiratory traces. Five traces were used: sin(2), sin(4), sin(6), and two patient traces. The optimal margin was defined as the margin for which the dose delivered to 95% of the target was closest to that obtained with no margin or motion. The equivalent uniform dose was also investigated as an alternative cost function.
Results: The optimal margin was always smaller than the peak-to-peak motion. When the respiratory trace spent less time in the inhale phases, the optimal margin was consistently smaller than when more time was spent in the inhale phases. The target size and treatment modality also affected the optimal margin.
Conclusions: The necessary margin for targets that spend less time in the exhale phase (sin(6)) is 2-4 mm smaller than for targets that spend equal time in the inhale and exhale phases (sin). (C) 2011 American Association of Physicists in Medicine. [DOI: 10.1118/1.3592649]

TI 3-D fiducial motion tracking using limited MV projections in arc therapy
SO MEDICAL PHYSICS

DT Article

method; image guidance
ID INTENSITY-MODULATED RADIOTHERAPY; REAL-TIME; IMRT
AB Purpose: In-treatment fiducial tracking has recently received attention as a method for improving treatment accuracy, dose conformity, and sparing of healthy tissue. 3-D fiducial localization in arc-radiotherapy remains challenging due to the motion of targets and the complexity of arc deliveries. We propose a novel statistical method for estimating 3-D fiducial motion using limited 2-D mega-voltage (MV) projections.
Methods: 3-D fiducial motion was estimated by a maximum a posteriori (MAP) approach to integrating information of fiducial projections with prior knowledge of target motion. To obtain the imaging geometries, short sequences of MV projections were selected in which fiducials were continuously visible. The MAP algorithm estimated the 3-D motion by maximizing the probability of displacement of fiducials in the sequences. Prior knowledge of target motion from a large statistical sample was built into the model to enhance the accuracy of estimation. In the case that a motion prior was unavailable, the algorithm can be simplified to the maximum likelihood (ML) approach. To compare tracking performance, a multiprojection geometric method was also presented by extending the typical two-project ion geometric estimation approach. The algorithms were evaluated using clinical prostate motion traces, and the performance was measured in quality indices and statistical evaluation.
Results: The results showed that the MAP method significantly outperforms the geometric method in all measures. In our simulations, the MAP method achieved an accuracy of less than 1 mm RMS error using only five continuous projections, whereas the geometric method required 15 projections to achieve a similar result.
Conclusions: The approach presented can accurately estimate tumor motion using a limited number of continuous projections. The MAP motion estimation is superior to both the ML and geometric estimation methods. (C) 2011 American Association of Physicists in Medicine. [DOI: 10.1118/1.3584197]

AB The FMS-like receptor tyrosine kinase 3 (FLT3) plays an important role in controlling differentiation and proliferation of hematopoietic cells. Activating mutations in FLT3 occur in patients with acute myeloid leukemia (AML; 15%-35%), resulting in abnormal cell proliferation. Furthermore, both adult and pediatric patients with AML harboring the FLT3 internal tandem duplication (ITD) mutation have a poor prognosis. Several inhibitors have been developed to target mutant FLT3 for the treatment of AML, yet the molecular pathways affected by drug inhibition of the mutated FLT3 receptor alone have not been characterized as yet. Linifanib (ABT-869) is a multitargeted tyrosine kinase receptor inhibitor that suppresses FLT3 signaling. In this article, we show that treatment with linifanib inhibits proliferation and induces apoptosis in ITD mutant cells in vitro and in vivo. We show that treatment with linifanib reduces phosphorylation of Akt and glycogen synthase kinase 3 beta (GSK3 beta). In addition, we show that inhibition of GSK3b decreases linifanib-induced apoptosis. This study shows the importance of GSK3 beta as a potential target for AML therapy, particularly in patients with FLT3 ITD mutations. Mol Cancer Ther; 10(6); 949-59. (C)2011 AACR.

AB Over the past 30 years, continuous progress in the application of nuclear magnetic resonance (NMR) spectroscopy and magnetic resonance spectroscopic imaging (MRSI) to the detection, diagnosis and characterization of human prostate cancer has turned what began as scientific curiosity into a useful clinical option. In vivo MRSI technology has been integrated into the daily care of prostate cancer patients, and innovations in ex vivo methods have helped to establish NMR-based prostate cancer metabolomics. Metabolomic and multimodality imaging could be the future of the prostate cancer clinic-particularly given the rationale that more accurate interrogation of a disease as complex as human prostate cancer is most likely to be achieved through paradigms involving multiple, instead of single and isolated, parameters. The research and clinical results achieved through in vivo MRSI and ex vivo NMR investigations during the first 11 years of the 21st century illustrate areas where these technologies can be best translated into clinical practice.

AB By application of the MRI method of diffusional kurtosis imaging, a substantially increased diffusional kurtosis was observed within the cerebral ischemic lesions of three stroke subjects, 13-26 h following the onset of symptoms. This increase is interpreted as probably reflecting a higher degree of diffusional heterogeneity in the lesions when compared with normal-appearing contralateral tissue. In addition, for two of the subjects with white matter infarcts, the increase had a strong fiber tract orientational dependence. It is proposed that this effect is consistent with a large drop in the intra-axonal diffusivity, possibly related to either axonal varicosities or alterations associated with the endoplasmic reticulum.

AB The use of combination antibiotic therapy for severe pseudomonal infections is a standard practice in many hospitals; however, the data supporting its use are somewhat unclear. Possible benefits of combination therapy for Pseudomonas aeruginosa infections include in vitro antibiotic synergy, prevention of the emergence of bacterial resistance while receiving therapy, and improved adequacy of empiric therapy. Unfortunately, the potential disadvantages are also considerable, the most worrisome of which are drug toxicity and creation of multidrug-resistant organisms in the environment. Many in vitro and animal studies have attempted to shed light on this clinically challenging issue; however, these studies have often yielded conflicting results and used different study methods, which limits the clinical utility of the results. Clinical studies have also attempted to clarify this issue, particularly in patients with serious pseudomonal infections such as bacteremia and ventilator-associated pneumonia, but again, often resulted in conflicting conclusions. Thus, we performed a MEDLINE search (1950-May 2010) of clinical and in vitro studies evaluating the use of antibiotic combination therapy and monotherapy for bacteremia and pneumonia due to P. aeruginosa. Although a clear answer still eludes this controversy, combination therapy for seriously ill patients suspected of having pseudomonal infection has been shown, with considerable evidence, to improve the likelihood of an active agent being included in the initial antibiotic regimen of these patients. The clinical status of the patient and true likelihood of encountering a multidrug-resistant organism should be evaluated before deciding on empiric combination therapy. Future research may be able to better identify which patient populations might receive the most benefit from combination therapy rather than using combination therapy for everyone at risk for these infections.

AB Psychologist practitioners are not immune to certain mental health problems, including suicidality, for which they provide services. In the aftermath of two recent psychologist suicides, the American Psychological Association's Advisory Committee on Colleague Assistance (ACCA) initiated the formation of a conjoint ad hoc committee consisting of members from ACCA, the American Psychological Association (APA) Practice Directorate, and the Section on Clinical Emergencies and Crises (Section VII of APA's Division 12) to investigate the incidence of psychologist suicide and its impact on colleagues, students or interns, patients or clients, and the profession. The committee reviewed the extant empirical literature on suicide rates for psychologists, evaluated unpublished data on psychologist suicide provided by the National Institute of Occupational Safety and Health (NIOSH), interviewed colleague survivors, reviewed published case reports of the impact of therapist suicides, and linked their findings to the literature on professional distress, impairment, and self-care. The committee concluded that there is evidence suggestive of an elevated risk of suicide for psychologists in past decades. It further concluded that there is a need for further research to confirm if there is a heightened risk of suicide for psychologists in the present day and to determine factors that might contribute to such risk. Accounts from colleague-survivors suggest that the impact of a psychologist's suicide can affect many people including family, colleagues, students, and patients or clients. This article offers suggestions for possible preventive approaches, for intervention with potentially at-risk colleagues, and for postvention efforts in the wake of a colleague suicide.

AB Objective: This study compared self-reported mental health status and current depression of female adult film performers and other young women. Methods: A cross-sectional structured online survey adapted from the California Women's Health Survey (CWHS) was self-administered to a convenience sample of 134 current female adult film performers via the Internet. Bivariate and multivariate analyses were used to compare data for these women with data for 1,773 women of similar ages who responded to the 2007 CWHS. Main outcome measures were self-reported mental health status, measured with the Behavioral Risk Factor Surveillance Survey core-instrument quality-of-life questions, and current depression, measured with the Patient Health Questionnaire-8. Results: Performers reported a mean of 7.2 days of poor mental health in the past 30 days, compared with 4.8 days for CWHS respondents, and 33% met criteria for current depression, compared with 13% of CWHS respondents (p<.01). As children, the adult film performers were more likely to have been victims of forced sex (37% compared with 13% of CWHS respondents), to have lived in poverty (24% and 12%), and to have been placed in foster care (21% and 4%) (p<.01). In the past 12 months, 50% of the performers reported living in poverty and 34% reported experiencing domestic violence, compared with 36% and 6%, respectively, of CWHS respondents (p<.01). As adults, 27% had experienced forced sex, compared with 9% of CWHS respondents (p<.01). Conclusions: Female adult film performers have significantly worse mental health and higher rates of depression than other California women of similar ages. (Psychiatric Services 62: 639-645, 2011)

AB Experts recommend that clinicians evaluating adults for attention-deficit/hyperactivity disorder (ADHD) obtain information from others who know the patient well. The authors examined correspondence between the self- and other-ratings of ADHD symptoms and impairment using 3 groups of adults recruited on the basis of their severity of ADHD: ADHD diagnosis (n = 146), clinical controls self-referring for ADHD but not diagnosed (n = 97), and community controls (n = 109). The influences of diagnostic group, informant relationship, sex of participant, IQ, and comorbid anxiety and depression on self-informant disparities were also examined. Results indicated moderate to high agreement (.59-.80) between self and others on current functioning and slightly lower levels (.53-.75) between self- and parent ratings of childhood functioning. Examination of difference scores between self- and other ratings revealed small mean disparities (-0.1 to +5.0 points) but substantial variation (SDs = -2.4 to 8.9 points) for both current and childhood ratings. Clinic referrals not diagnosed with ADHD, particularly women, had higher disparities than was evident in the ADHD and community groups. Age, IQ, and education were not associated with disparities in most ratings. Higher anxiety, in contrast, was associated with greater disparities on all current and childhood measures of both ADHD and impairment.

AB Oregon Violent Death Reporting System data were linked with Veterans Affairs (VA) administrative data to identify and describe veterans who completed suicide in Oregon from 2000 to 2005 (n = 968), and to describe their VA health care utilization in the year prior to death. Twenty-two percent had received health care in the VA system. Of these, 57% did not have mental health diagnoses and 58% had not seen mental health professionals. A larger proportion of those who accessed care were VA-enrolled and received service-connected disability benefits. Fifty-five veterans were hospitalized during the year prior to death. Of these, 33% completed suicide within 30 days of a hospitalization. Further development of suicide prevention strategies for veterans in the community, including general medical treatment settings, is indicated.

AB Background: Thyrotoxicosis has multiple etiologies, manifestations, and potential therapies. Appropriate treatment requires an accurate diagnosis and is influenced by coexisting medical conditions and patient preference. This article describes evidence-based clinical guidelines for the management of thyrotoxicosis that would be useful to generalist and subspeciality physicians and others providing care for patients with this condition.
Methods: The development of these guidelines was commissioned by the American Thyroid Association in association with the American Association of Clinical Endocrinologists. The American Thyroid Association and American Association of Clinical Endocrinologists assembled a task force of expert clinicians who authored this report. The task force examined relevant literature using a systematic PubMed search supplemented with additional published materials. An evidence-based medicine approach that incorporated the knowledge and experience of the panel was used to develop the text and a series of specific recommendations. The strength of the recommendations and the quality of evidence supporting each was rated according to the approach recommended by the Grading of Recommendations, Assessment, Development, and Evaluation Group.
Results: Clinical topics addressed include the initial evaluation and management of thyrotoxicosis; management of Graves' hyperthyroidism using radioactive iodine, antithyroid drugs, or surgery; management of toxic multinodular goiter or toxic adenoma using radioactive iodine or surgery; Graves' disease in children, adolescents, or pregnant patients; subclinical hyperthyroidism; hyperthyroidism in patients with Graves' ophthalmopathy; and management of other miscellaneous causes of thyrotoxicosis.
Conclusions: One hundred evidence-based recommendations were developed to aid in the care of patients with thyrotoxicosis and to share what the task force believes is current, rational, and optimal medical practice.

AB From the fertilization of an egg until the death of an individual, somatic cells can accumulate genetic changes, such that cells from different tissues or even within the same tissue differ genetically. The presence of multiple cell clones with distinct genotypes in the same individual is referred to as 'somatic mosaicism'. Many endogenous factors such as mobile elements, DNA polymerase slippage, DNA double-strand break, inefficient DNA repair, unbalanced chromosomal segregation and some exogenous factors such as nicotine and UV exposure can contribute to the generation of somatic mutations, thereby leading to somatic mosaicism. Such changes can potentially affect the epigenetic patterns and levels of gene expression, and ultimately the phenotypes of cells. Although recent studies suggest that somatic mosaicism is widespread during normal development and aging, its implications for heightened disease risks are incompletely understood. Here, I discuss the origins, prevalence and implications of somatic mosaicism in healthy human tissues.

AB Load-bearing tissues owe their mechanical strength to their highly anisotropic collagenous structure. To date attempts to engineer mechanically strong connective tissue have failed, mainly due to a lack of ability to reproduce the native collagen organization in constructs synthesized by cultured cells in vitro. The ability to influence the orientation of self-assembling collagen molecules to produce highly anisotropic structures has applications ranging from de novo engineering of complex tissues to the production of organized scaffolds for cell culture contact guidance. In this investigation we have used the simple technique of spin-coating to produce highly aligned arrays of collagen fibrils. By a simple modification of the method we have also successfully produced orthogonal collagen lamellae. Alternating collagen lamellae are frequently seen in load-bearing tissues such as cornea, annulus fibrosus, and cortical bone. Culturing of corneal fibroblasts on aligned collagen shows that the cells adopt the organization of fibrils. In this investigation we observed the reversal of fibrillar growth direction or "hook" formation similar to that seen previously in a microfluidic shear flow chamber. Although the results of this investigation clearly show that it is possible to produce small areas (1 cm(2)) of collagen fibrils with enough alignment to guide fibroblasts, there is evidence that thin film instabilities are likely to be a significant barrier to producing organized collagen fibrils over larger areas. Successful application of this method to produce highly controlled and organized collagenous structures will require the development of techniques to control thin film instability and will be the subject of future work.

ID IMMUNIZATION; ATTITUDES
AB The goals of this study were to define the uptake of H1N1 and seasonal influenza vaccination during pregnancy among women delivering during the 2009 H1N1 pandemic and explore barriers to vaccination. All postpartum women at the Massachusetts General Hospital from January 2010 through March 2010 were invited to complete an anonymous questionnaire about demographics, vaccination status, and attitudes about vaccination during pregnancy. Among 370 participants (53% response rate), 81% accepted both the H1N1 and seasonal influenza vaccines during pregnancy. Patients who declined one or both vaccines cited concerns over safety as a major deterrent. Of the 36% of participants who reported having flu-like symptoms during this pregnancy only 8.6% took oseltamivir. While a high vaccination rate was identified in this study, further education is needed to reassure patients regarding vaccine safety. Education for providers and patients emphasizing the benefits of early treatment of pregnant women with flu-like symptoms should be a priority.

Hyperactivity Disorder: A Family Risk Analysis
SO AMERICAN JOURNAL OF PSYCHIATRY
LA English
DT Article
ID PEDIATRIC BIPOLAR DISORDER; SUBTHRESHOLD DIAGNOSES; LATE-ONSET;
DEFICIT/HYPERACTIVITY DISORDER; ADHD ADULTS; TRAITS
AB Objective: A growing body of research suggests that deficient emotional self-regulation (DESR) is prevalent and morbid among patients with attention deficit hyperactivity disorder (ADHD). Family studies provide a method of clarifying the co-occurrence of clinical features, but no family studies have yet addressed ADHD and DESR.
Method: Participants were 83 probands with and without ADHD and 128 siblings. All were assessed for axis I DSM-IV conditions with structured diagnostic interviews. The authors defined DESR in adult probands and siblings using items from the Barkley Current Behavior Scale. Analyses tested hypotheses about the familial relationship between ADHD and DESR.
Results: Siblings of ADHD probands were at elevated risk of having ADHD, irrespective of the presence or absence of DESR in the proband. The risk for DESR was elevated in siblings of ADHD plus DESR probands but not in siblings of ADHD probands. ADHD and DESR cosegregated in siblings. The risk for other psychiatric disorders was similar in siblings of the ADHD proband groups.
Conclusions: The pattern of inheritance of ADHD with DESR preliminarily suggests that DESR may be a familial subtype of ADHD. Our data suggest that DESR is not an expression of other axis I DSM-IV disorders or of nonfamilial environmental factors. The authors cannot exclude contribution of non-axis-I DSM-IV disorders to risk for DESR and cannot determine whether the cosegregation of ADHD in DESR within families is a result of genes or familial environmental risk factors. Further investigation of DESR and its correlates and treatment both in and outside the context of ADHD is warranted.

AB We recently reported long-term organ allograft survival without ongoing immunosuppression in four of five patients receiving combined kidney and bone marrow transplantation from haploidentical donors following nonmyeloablative conditioning. In vitro assays up to 18 months revealed donor-specific unresponsiveness. We now demonstrate that T cell recovery is gradual and is characterized by memory-type cell predominance and an increased proportion of CD4+CD25+CD127-FOXP3+ Treg during the lymphopenic period. Complete donor-specific unresponsiveness in proliferative and cytotoxic assays, and in limiting dilution analyses of IL-2-producing and cytotoxic cells, developed and persisted for the 3-year follow-up in all patients, and extended to donor renal tubular epithelial cells. Assays in two of four patients were consistent with a role for a suppressive tolerance mechanism at 6 months to 1 year, but later (>= 18 months) studies on all four patients provided no evidence for a suppressive mechanism. Our studies demonstrate, for the first time, long-term, systemic donor-specific unresponsiveness in patients with HLA-mismatched allograft tolerance. While regulatory cells may play an early role, long-term tolerance appears to be maintained by a deletion or anergy mechanism.

AB CD4+ Tregs specific for noninherited maternal antigens (NIMAd) are detectable in some but not all B6 x BDF(1) backcross, H-2b homozygous offspring, and their presence is strongly correlated with extent of maternal (BDF(1)) microchimerism. We hypothesized that the level of pretransplant donor antigen-specific Tregs could predict allograft tolerance. To test this idea, mice were screened for bystander suppression in a DTH assay, followed 1 week later by DBA/2 heterotopic heart transplantation. NIMAd-exposed, H-2b offspring that failed to suppress DTH uniformly rejected heart allografts (12/12) by d15. In contrast, 5/6 NIMAd-exposed DTH 'regulators' accepted their allografts > 100 days. The defect in 'nonregulator" offspring could be corrected by transfer of CD4+CD25+, but not CD4+CD25neg or CD8+T cells from transplant acceptor mice. In conclusion, donor-specific T reg screening of F1 backcross offspring correctly predicted which recipients would accept a heart allograft. If translated to the clinic, similar pretransplant Treg screening could greatly enhance the effectiveness of tolerance as a clinical strategy in transplantation between family members.

AB Background: Epidermal growth factor receptor (EGFR) is overexpressed in a significant proportion of esophageal and gastric carcinomas. Although previous studies have examined tyrosine kinase inhibitors of EGFR, there remains limited data regarding the role of EGFR-directed monoclonal antibody therapy in these malignancies. We carried out a multi-institutional phase II study of cetuximab, a monoclonal antibody against EGFR, in patients with unresectable or metastatic esophageal or gastric adenocarcinoma.
Patients and Methods: Thirty-five patients with previously treated metastatic esophageal or gastric adenocarcinoma were treated with weekly cetuximab, at an initial dose of 400 mg/m(2) followed by weekly infusions at 250 mg/m(2). Patients were followed for toxicity, treatment response, and survival.
Results: Treatment with cetuximab was well tolerated; no patients were taken off study due to drug-related adverse events. One (3%) partial treatment response was noted. Two (6%) patients had stable disease after 2 months of treatment. Median progression-free survival and overall survival were 1.6 and 3.1 months, respectively.
Conclusion: Although well tolerated, cetuximab administered as a single agent had minimal clinical activity in patients with metastatic esophageal and gastric adenocarcinoma. Ongoing studies of EGFR inhibitors in combination with other agents may define a role for these agents in the treatment of esophageal and gastric cancer.

AB Background: This study was designed to determine the safety, pharmacokinetics (PK) and pharmacodynamics (PD) of brivanib in patients with advanced/metastatic solid tumors.
Patients and methods: Ninety patients enrolled in this two-part, phase I open-label study of oral brivanib alaninate. The primary objectives of this study were (in part A) dose-limiting toxicity, maximum tolerated dose (MTD) and the lowest biologically active dose level and (in part B) the optimal dose/dose range. The secondary objectives of this study were preliminary evidence of antitumor activity, PK and PD.
Results: Across part A (open-label dose escalation and MTD) and part B (open-label dose optimization), 68 patients received brivanib alaninate. Brivanib demonstrated a manageable toxicity profile at doses of 180-800 mg. Most toxic effects were mild. Systemic exposure of the active moiety brivanib increased linearly <= 1000 mg/day. The MTD was 800 mg/day. Forty-four patients were treated at the MTD: 20 with 800 mg continuously, 11 with 800 mg intermittently and 13 with 400 mg b.i.d. doses. Partial responses were confirmed in two patients receiving brivanib 600 mg. Dynamic contrast-enhanced magnetic resonance imaging demonstrated statistically significant decreases in parameters reflecting tumor vascularity and permeability after multiple doses in the 800-mg continuous q.d. and 400-mg b.i.d. dose cohorts.
Conclusion: In patients with advanced/metastatic cancer, brivanib demonstrates promising antiangiogenic and antitumor activity and manageable toxicity at doses <= 800 mg orally q.d., the recommended phase II study dose.

AB Objective: Chronic inflammation plays a pivotal role in the development and progression of atherosclerosis. The inflammatory response is mediated by cytokines. The aim of this study was to determine if OncostatinM(OSM), a monocyte and T-lymphocyte specific cytokine is present in atherosclerotic lesions. We also investigated the roles of signal transducer and activator of transcription (STAT)-1 and STAT-3 in regulating OSM-induced smooth muscle cell (SMC) proliferation, migration and cellular fibronectin (cFN) synthesis.
Methods and results: Immunostaining of atherosclerotic lesions from human carotid plaques demonstrated the expression of OSM antigen in both macrophages and SMCs. Explanted SMCs from human carotid plaques expressed OSM mRNA and protein as determined by RT-PCR and Western blotting. Using the chow-fed ApoE-/- mouse model of atherosclerosis, we observed that OSM was initially expressed in the intima at 20 weeks of age. By 30 weeks, OSM was expressed in both the intima and media. In vitro studies show that OSM promotes SMC proliferation, migration and cFN synthesis. Lentivirus mediated-inhibition of STAT-1 and STAT-3 prevented OSM-induced SMC proliferation, migration and cellular fibronectin synthesis.
Conclusions: These findings demonstrate that OSM is expressed in atherosclerotic lesions and may contribute to the progression of atherosclerosis by promoting SMC proliferation, migration and extracellular matrix protein synthesis through the STAT pathway. Published by Elsevier Ireland Ltd.

AB Macroautophagy is a highly conserved catabolic process that is crucial for organ homeostasis in mammals. However, methods to directly measure macroautophagic activity (or flux) in vivo are limited. In this study we developed a quantitative macroautophagic flux assay based on measuring LC3b protein turnover in vivo after administering the protease inhibitor leupeptin. Using this assay we then characterized basal macroautophagic flux in different mouse organs. We found that the rate of LC3b accumulation after leupeptin treatment was greatest in the liver and lowest in spleen. Interestingly we found that LC3a, an ATG8/LC3b homologue and the LC3b-interacting protein p62 were degraded with similar kinetics to LC3b. However, the LC3b-related proteins GABARAP and GATE-16 were not rapidly turned over in mouse liver, implying that different LC3b homologues may contribute to macroautophagy via distinct mechanisms. Nutrient starvation augmented macroautophagic flux as measured by our assay, while refeeding the animals after a period of starvation significantly suppressed flux. We also confirmed that beclin 1 heterozygous mice had reduced basal macroautophagic flux compared to wild-type littermates. These results illustrate the usefulness of our leupeptin-based assay for studying the dynamics of macroautophagy in mice.

AB Normal differentiated cells rely primarily on mitochondrial oxidative phosphorylation to produce adenosine triphosphate (ATP) to maintain their viability and functions by using three major bioenergetic fuels: glucose, glutamine and fatty acids. Many cancer cells, however, rely on aerobic glycolysis for their growth and survival, and recent studies indicate that some cancer cells depend on glutamine as well. This altered metabolism in cancers occurs through oncogene activation or loss of tumor suppressor genes in multiple signaling pathways, including the phosphoinositide 3-kinase and Myc pathways. Relatively little is known, however, about the role of fatty acids as a bioenergetic fuel in growth and survival of cancer cells. Here, we report that human glioblastoma SF188 cells oxidize fatty acids and that inhibition of fatty acid beta-oxidation by etomoxir, a carnitine palmitoyltransferase 1 inhibitor, markedly reduces cellular ATP levels and viability. We also found that inhibition of fatty acid oxidation decreases nicotinamide adenine dinucleotide phosphate (NADPH) levels and the reduced glutathione (GSH) content and elevates intracellular reactive oxygen species. These results suggest that modulation of fatty acid oxidation controls the NADPH level. In the presence of reactive oxygen species scavenger tiron, however, ATP depletion is prevented without restoring fatty acid oxidation. This suggests that oxidative stress may lead to bioenergetic failure and cell death. Our work provides evidence that mitochondrial fatty acid oxidation may provide NADPH for defense against oxidative stress and prevent ATP loss and cell death.

AB Patients with hematologic malignancies undergoing allogeneic stem cell transplantation (HSCT) commonly have an elevated serum ferritin prior to HSCT, which has been associated with increased mortality after transplantation. This has led to the suggestion that iron overload is common and deleterious in this patient population. However, the relationship between serum ferritin and parenchymal iron overload in such patients is unknown. We report a prospective study of 48 patients with acute leukemia (AL) or myelodysplastic syndromes (MDS) undergoing myeloablative HSCT, using magnetic resonance imaging (MRI) to estimate liver iron content (LIC) and cardiac iron. The median (and range) pre-HSCT value of serum ferritin was 1549 ng/mL (20-6989); serum hepcidin, 59 ng/mL (10-468); labile plasma iron, 0 LPI units (0.0-0.9). Eighty-five percent of patients had hepatic iron overload (HIO), and 42% had significant HIO (LIC >= 5.0 mg/gdw). Only I patient had cardiac iron overload. There was a strong correlation between pre-HSCT serum ferritin and estimated LIC (r = .75), which was mostly dependent on prior transfusion history. Serum hepcidin was appropriately elevated in patients with HIO. Labile plasma iron elevation was rare. A regression calibration analysis supported the hypothesis that elevated pre-HSCT LIC is significantly associated with inferior post-HSCT survival. These results contribute to our understanding of the prevalence, mechanism, and consequences of iron overload in HSCT.

ID PELVIC FLOOR; SECTION; RISKS
AB Background:
Cesarean delivery rates have been rising rapidly in many countries in the last decade. The objective of this research is to examine cesarean rates in industrialized countries and assess patterns in the trends toward increasing rates.
Methods:
We examined cesarean delivery rates per 1,000 live births from 1987 to 2007 in 22 industrialized countries. To enhance comparability, the inclusion criteria were at least 50,000 births annually and a per capita gross domestic product of at least U.S.$10,000 in 2007. Poisson regression was selected to model the cesarean delivery rates of countries across time.
Results:
We examined overall cesarean delivery rates, absolute changes in these rates, and changes in trend lines for cesarean rates for the period from 1987 to 2007. In 2007, 11 of the 21 countries reported overall cesarean rates of more than 25 percent, led by Italy (39%), Portugal (35%), the United States (32%), and Switzerland (32%). Five countries, the Slovak Republic, Czech Republic, Ireland, Austria, and Hungary more than doubled their cesarean delivery rate between 1992 and 2007. Comparing changes in rates across time periods, 14 countries experienced a greater increase in rates in the period between 1998 and 2002 compared with the period between 1993 and 1997. Comparing trends from 2003-2007 to 1998-2002, eighteen countries experienced a slowing down of rate increases across these two periods.
Conclusion:
Although cesarean delivery rates continue to rise, the rate of increase appears to be slowing down in most industrialized countries. (BIRTH 38:2 June 2011).

AB Late complications of allogeneic hematopoietic stem cell transplantation (HSCT) include a risk of secondary malignancies. Optimization for early diagnosis and treatment of oral premalignant or malignant lesions requires an assessment of potential predisposing risk factors. The medical records of patients who developed oral epithelial dysplasia (OED) and oral squamous cell carcinoma (OSCC) following allogeneic-HSCT were reviewed. Data on HSCT course, chronic graft-versus-host disease (cGVHD), and clinical outcome were recorded; landmark survival was calculated. Twenty-six patients with OED (n = 8) and OSCC (n = 18) were identified with a median follow-up of 26.5 and 21.5 months, respectively. Premalignant and malignant oral lesions were diagnosed at a median time of 2.5 and 8 years after HSCT, respectively. Chronic GVHD was present in 96% of patients and of these, 96% had oral involvement. Multifocal oral cancer was found in 28% of cases, and localized recurrence was observed in 44% of cases. These results suggest that oral cGVHD may be considered a potential risk factor for the development of OSCC following allogeneic-HSCT. The observation that oral cancers were frequently multifocal and recurred locally suggests that these cancers may be more aggressive. Vigilant follow-up and coordination of care are critical.

ANALYSIS
AB Disruption of functional connectivity between brain regions may represent an early functional consequence of beta-amyloid pathology prior to clinical Alzheimer's disease. We aimed to investigate if non-demented older individuals with increased amyloid burden demonstrate disruptions of functional whole-brain connectivity in cortical hubs (brain regions typically highly connected to multiple other brain areas) and if these disruptions are associated with neuronal dysfunction as measured with fluorodeoxyglucose-positron emission tomography. In healthy subjects without cognitive symptoms and patients with mild cognitive impairment, we used positron emission tomography to assess amyloid burden and cerebral glucose metabolism, structural magnetic resonance imaging to quantify atrophy and novel resting state functional magnetic resonance imaging processing methods to calculate whole-brain connectivity. Significant disruptions of whole-brain connectivity were found in amyloid-positive patients with mild cognitive impairment in typical cortical hubs (posterior cingulate cortex/precuneus), strongly overlapping with regional hypometabolism. Subtle connectivity disruptions and hypometabolism were already present in amyloid-positive asymptomatic subjects. Voxel-based morphometry measures indicate that these findings were not solely a consequence of regional atrophy. Whole-brain connectivity values and metabolism showed a positive correlation with each other and a negative correlation with amyloid burden. These results indicate that disruption of functional connectivity and hypometabolism may represent early functional consequences of emerging molecular Alzheimer's disease pathology, evolving prior to clinical onset of dementia. The spatial overlap between hypometabolism and disruption of connectivity in cortical hubs points to a particular susceptibility of these regions to early Alzheimer's-type neurodegeneration and may reflect a link between synaptic dysfunction and functional disconnection.

AB Previous studies have shown that intestinal tumors from Apc(Min/+) (Min) mice and familial adenomatous polyposis (FAP) patients are often polyclonal. We sought to determine whether polyclonality is unique to tumors arising from hereditary predispositions or, instead, is a common feature of intestinal tumorigenesis in other pathways to tumorigenesis. Ethylnitrosourea-induced intestinal tumors from mice wild type at the Apc locus and chimeric for the Rosa26 lineage marker were analyzed. Many were overtly polyclonal, being composed of a mixture of Rosa26(+) and Rosa26(-) neoplastic cells. Statistical analyses revealed that polyclonality could be explained by interactions between two initiated clones separated by a very short distance. The frequency of overtly polyclonal tumors and the range of interactions estimated in this model are similar to those observed when analyzing familial tumors from Min mice. Thus, polyclonality does not depend on the familial pathway to tumorigenesis. Interactions between two initiated clones might provide a selective advantage during the early stages of intestinal tumorigenesis. Cancer Prev Res; 4(6); 916-23. (C) 2011 AACR.

AB Proton magnetic resonance spectroscopy is increasingly used in clinical studies of brain tumor to provide information about tissue metabolic profiles. In this study, we evaluated changes in the levels of metabolites predominant in recurrent glioblastoma multiforme (rGBM) to characterize the response of rGBM to antiangiogenic therapy. We examined 31 rGBM patients treated with daily doses of cediranib, acquiring serial chemical shift imaging data at specific time points during the treatment regimen. We defined spectra from three regions of interest (ROI)-enhancing tumor (ET), peritumoral tissue, and normal tissue on the contralateral side (cNT)-in post-contrast T1-weighted images, and normalized the concentrations of N-acetylaspartate (NAA) and choline (Cho) in each ROI to the concentration of creatine in cNT (norCre). We analyzed the ratios of these normalized metabolites (i.e., NAA/Cho, NAA/norCre, and Cho/norCre) by averaging all patients and categorizing two different survival groups. Relative to pretreatment values, NAA/Cho in ET was unchanged through day 28. However, after day 28, NAA/Cho significantly increased in relation to a significant increase in NAA/norCre and a decrease in Cho/norCre; interestingly, the observed trend was reversed after day 56, consistent with the clinical course of GBM recurrence. Notably, receiver operating characteristic analysis indicated that NAA/Cho in tumor shows a high prediction to 6-month overall survival. These metabolic changes in these rGBM patients strongly suggest a direct metabolic effect of cediranib and might also reflect an antitumor response to antiangiogenic treatment during the first 2 months of treatment. Further study is needed to confirm these findings. Cancer Res; 71(11); 3745-52. (C)2011 AACR.

POLARITY; PROTEIN; ACINI; PHOSPHORYLATION; OVEREXPRESSION
AB c-Myc is an oncogene transcription factor that causes cancer in many settings, including solid tumors that arise in the context of organized tissue structures. Given that disruption of tissue architecture frequently occurs in cancer, there is considerable interest in how cell organization impacts oncogene function. A previous report found that organization of mammary epithelial cells into defined 3-dimensional structures renders them insensitive to the effects of retrovirus-mediated overexpression of Myc, leading to the notion that organization tempers the sensitivity of individual cells to Myc activity. In this article, we report that epithelial cell organization does not profoundly alter Myc activity but, instead, suppresses Myc by modulating its expression. We show that the morphogenesis of mammary epithelial cells into organized acinar structures in vitro is accompanied by widespread changes in gene expression patterns, including a substantial decrease in the expression of Myc. Concomitant with the decrease in endogenous Myc expression, we observe a decrease in transcription from retroviral vectors during morphogenesis and find that Myc transgene expression in acini is much lower than in unorganized cells. This decrease in Myc transgene activity is responsible for the apparent recalcitrance of organized cells to ectopic Myc, as adenovirus-mediated expression of Myc in organized structures potently induces apoptosis. These observations reveal that organization does not alter the inherent response of epithelial cells to Myc and suggest that other tumor suppression mechanisms, apart from structure, antagonize Myc in the development of solid tumors.

AB Defective microRNA (miRNA) biogenesis contributes to the development and progression of epithelial ovarian cancer (EOC). In this study, we examined the hypothesis that single nucleotide polymorphisms (SNP) in miRNA biogenesis genes may influence EOC risk. In an initial investigation, 318 SNPs in 18 genes were evaluated among 1,815 EOC cases and 1,900 controls, followed up by a replicative joint meta-analysis of data from an additional 2,172 cases and 3,052 controls. Of 23 SNPs from 9 genes associated with risk (empirical P < 0.05) in the initial investigation, the meta-analysis replicated 6 SNPs from the DROSHA, FMR1, LIN28, and LIN28B genes, including rs12194974 (G>A), an SNP in a putative transcription factor binding site in the LIN28B promoter region (summary OR = 0.90, 95% CI: 0.82-0.98; P = 0.015) which has been recently implicated in age of menarche and other phenotypes. Consistent with reports that LIN28B overexpression in EOC contributes to tumorigenesis by repressing tumor suppressor let-7 expression, we provide data from luciferase reporter assays and quantitative RT-PCR to suggest that the inverse association among rs12194974 A allele carriers may be because of reduced LIN28B expression. Our findings suggest that variants in LIN28B and possibly other miRNA biogenesis genes may influence EOC susceptibility. Cancer Res; 71(11); 3896-903. (C) 2011 AACR.

AB Background: There is conflicting data regarding the impact of obesity on morbidity and mortality in patients undergoing isolated coronary artery bypass grafting (CABG).
Methods and Results: Retrospective cohort analysis of patients who underwent CABG from January 1, 1995, through July 31, 2010 was performed. Patients were classified as obese or non-obese (body mass index >= 30.0 kg/m(2) and <30.0 kg/m(2), respectively). The primary outcome was in-hospital mortality. Secondary outcomes included postoperative respiratory failure, postoperative stroke, postoperative myocardial infarction, sternal and leg wound infections, postoperative atrial fibrillation, postoperative ventricular tachycardia, postoperative renal failure and length of hospital stay. Propensity-matched stepwise multivariable logistic regression was performed. Of 13,115 patients, 4,619 (35.2%) were obese. In the propensity-matched logistic regression models (n=8,442), obesity was not associated with postoperative mortality (odds ratio=1.13, 95% confidence interval 0.86-1.48). However, obesity was associated with postoperative respiratory failure, postoperative renal insufficiency, sternal wound infection, and leg wound infection. Obesity was also associated with a decreased risk of postoperative bleeding and re-operation from bleeding.
Conclusions: Obesity was associated with an increased risk of postoperative respiratory failure, postoperative renal failure, and surgical site infections. However, obesity was not associated with in-hospital mortality in patients undergoing CABG. (Circ J 2011; 75: 1378-1385)

TI Relationships between muscle contributions to walking subtasks and
functional walking status in persons with post-stroke hemiparesis

ID MECHANICAL-PROPERTIES; GAIT SPEED; STROKE; SUPPORT; PROGRESSION; WORK;
CLASSIFICATION; OPTIMIZATION; FLEXORS; FORCES
AB Background: Persons with post-stroke hemiparesis usually walk slowly and asymmetrically. Stroke severity and functional walking status are commonly predicted by post-stroke walking speed. The mechanisms that limit walking speed, and by extension functional walking status, need to be understood to improve post-stroke rehabilitation methods.
Methods: Three-dimensional forward dynamics walking simulations of hemiparetic subjects (and speed-matched controls) with different levels of functional walking status were developed to investigate the relationships between muscle contributions to walking subtasks and functional walking status. Muscle contributions to forward propulsion, swing initiation and power generation were analyzed during the pre-swing phase of the gait cycle and compared between groups.
Findings: Contributions from the paretic leg muscles (i.e., soleus, gastrocnemius and gluteus medius) to forward propulsion increased with improved functional walking status, with the non-paretic leg muscles (i.e., rectus femoris and vastii) compensating for reduced paretic leg propulsion in the limited community walker. Contributions to swing initiation from both paretic (i.e., gastrocnemius, iliacus and psoas) and non-paretic leg muscles (i.e., hamstrings) also increased as functional walking status improved. Power generation was also an important indicator of functional walking status, with reduced paretic leg power generation limiting the paretic leg contribution to forward propulsion and leg swing initiation.
Interpretation: These results suggest that deficits in muscle contributions to the walking subtasks of forward propulsion, swing initiation and power generation are directly related to functional walking status and that improving output in these muscle groups may be an effective rehabilitation strategy for improving post-stroke hemiparetic walking.

AB Purpose: Unlike platelet-derived growth factor-B (PDGF-B), the role of PDGF-D in tumor progression or treatment is largely unknown. To this end, we determined the role of PDGF-D in breast cancer progression, metastasis, and response to chemotherapy.
Experimental Design: We first examined PDGF-D expression in human breast carcinomas by immunohistochemical (IHC) staining. To mimic high PDGF-D expressing tumors, we stably transfected the breast cancer cell lines MDA-MB-231 and 4T1 with pdgf-d cDNA, and implanted these tumor cells orthtopically into nude mice. We monitored tumor growth by caliper measurement and bioluminescence imaging. We also used short hairpin RNA interference (shRNAi) and imatinib to block PDGF-D/PDGFR beta signaling. Finally, we studied the effect of PDGF-D on doxorubicin delivery and efficacy.
Results: Human breast cancers express high levels of PDGF-D. Overexpression of PDGF-D promoted tumor growth and lymph node metastasis through increased proliferation, decreased apoptosis, and induction of CXCR4 expression. Blockade of CXCR4 signaling abolished PDGF-D-induced lymph node metastasis. Furthermore, overexpression of PDGF-D increased perivascular cell coverage and normalized tumor blood vessels. As a result, PDGF-D overexpression facilitated tissue penetration of doxorubicin and enhanced its treatment efficacy.
Conclusions: PDGF-D is highly expressed in human breast cancer and facilitates tumor growth and lymph node metastasis, making it a potential target in breast cancer. At the same time, PDGF-D increases drug delivery and hence improves the efficacy of chemotherapy through vessel normalization. Therefore, judicious use of PDGF-D/PDGFR beta blockers would be necessary to minimize the adverse effects on concomitantly administered cytotoxic therapies. Clin Cancer Res; 17(11); 3638-48.

AB Purpose: We evaluated the utility of chimeric gamma c homeostatic cytokine, IL-7/IL-7R alpha-Fc, to restore host APC (antigen presenting cell) and T cell activities in lung cancer.
Experimental Design: Utilizing murine lung cancer models we determined the antitumor efficacy of IL-7/IL-7R alpha-Fc. APC, T cell, cytokine analyses, neutralization of CXCL9, CXCL10, and IFN gamma were carried out to evaluate the mechanistic differences in the antitumor activity of IL-7/IL-7R alpha-Fc in comparison to controls.
Results: IL-7/IL-7R alpha-Fc administration inhibited tumor growth and increased survival in lung cancer. Accompanying the tumor growth inhibition were increases in APC and T cell activities. In comparison to controls, IL-7/IL-7R alpha-Fc treatment of tumor bearing mice led to increased: (i) levels of CXCL9, CXCL10, IFN gamma, IL-12 but reduced IL-10 and TGF beta, (ii) tumor macrophage infiltrates characteristic of M1 phenotype with increased IL-12, iNOS but reduced IL-10 and arginase, (iii) frequencies of T and NK cells, (iv) T cell activation markers CXCR3, CD69 and CD127(low), (v) effector memory T cells, and (vi) T cell cytolytic activity against parental tumor cells. IL-7/IL-7R alpha-Fc treatment abrogated the tumor induced reduction in splenic functional APC activity to T responder cells. The CXCR3 ligands played an important role in IL-7/IL-7R alpha-Fc-mediated antitumor activity. Neutralization of CXCL9, CXCL10, or IFN gamma reduced CXCR3 expressing activated T cells infiltrating the tumor and abrogated IL-7/IL-7R alpha-Fc-mediated tumor growth inhibition.
Conclusions: Our findings show that IL-7/IL-7R alpha-Fc promotes afferent and efferent antitumor responses in lung cancer. Clin Cancer Res; 17(11); 3660-72. (C)2011 AACR.

AB Purpose: To develop a new oncolytic herpes simplex virus (oHSV) for glioblastoma (GBM) therapy that will be effective in glioblastoma stem cells (GSC), an important and untargeted component of GBM. One approach to enhance oHSV efficacy is by combination with other therapeutic modalities.
Experimental Design: MG18L, containing a U(S)3 deletion and an inactivating LacZ insertion in U(L)39, was constructed for the treatment of brain tumors. Safety was evaluated after intracerebral injection in HSV-susceptible mice. The efficacy of MG18L in human GSCs and glioma cell lines in vitro was compared with other oHSVs, alone or in combination with phosphoinositide-3-kinase (PI3K)/Akt inhibitors (LY294002, triciribine, GDC-0941, and BEZ235). Cytotoxic interactions between MG18L and PI3K/Akt inhibitors were determined using Chou-Talalay analysis. In vivo efficacy studies were conducted using a clinically relevant mouse model of GSC-derived GBM.
Results: MG18L was severely neuroattenuated in mice, replicated well in GSCs, and had anti-GBM activity in vivo. PI3K/Akt inhibitors displayed significant but variable antiproliferative activities in GSCs, whereas their combination with MG18L synergized in killing GSCs and glioma cell lines, but not human astrocytes, through enhanced induction of apoptosis. Importantly, synergy was independent of inhibitor sensitivity. In vivo, the combination of MG18L and LY294002 significantly prolonged survival of mice, as compared with either agent alone, achieving 50% long-term survival in GBM-bearing mice.
Conclusions: This study establishes a novel therapeutic strategy: oHSV manipulation of critical oncogenic pathways to sensitize cancer cells to molecularly targeted drugs. MG18L is a promising agent for the treatment of GBM, being especially effective when combined with PI3K/Akt pathway-targeted agents. Clin Cancer Res; 17(11); 3686-96. (C)2011 AACR.

Implications for Clinical Testing

ID GENOME-WIDE ASSOCIATION; SUSCEPTIBILITY LOCI; MUTATION CARRIERS;
BREAST-CANCER; RISK; CONSORTIUM; SURVIVAL
AB Purpose: An assay for the single-nucleotide polymorphism (SNP), rs61764370, has recently been commercially marketed as a clinical test to aid ovarian cancer risk evaluation in women with family histories of the disease. rs67164370 is in a 3'-UTR miRNA binding site of the KRAS oncogene and is a candidate for epithelial ovarian cancer (EOC) susceptibility. However, only one published article, analyzing fewer than 1,000 subjects in total, has examined this association.
Experimental Design: Risk association was evaluated in 8,669 cases of invasive EOC and 10,012 controls from 19 studies participating in the Ovarian Cancer Association Consortium, and in 683 cases and 2,044 controls carrying BRCA1 mutations from studies in the Consortium of Investigators of Modifiers of BRCA1/2. Prognosis association was also examined in a subset of five studies with progression-free survival (PFS) data and 18 studies with all-cause mortality data.
Results: No evidence of association was observed between genotype and risk of unselected EOC (OR = 1.02, 95% CI: 0.95-1.10), serous EOC (OR = 1.08, 95% CI: 0.98-1.18), familial EOC (OR = 1.09, 95% CI: 0.78-1.54), or among women carrying deleterious mutations in BRCA1 (OR = 1.09, 95% CI: 0.88-1.36). There was little evidence for association with survival time among unselected cases (HR = 1.10, 95% CI: 0.99-1.22), among serous cases (HR = 1.12, 95% CI = 0.99-1.28), or with PFS in 540 cases treated with carboplatin and paclitaxel (HR = 1.18, 95% CI: 0.93-1.52).
Conclusions: These data exclude the possibility of an association between rs61764370 and a clinically significant risk of ovarian cancer or of familial ovarian cancer. Use of this SNP for ovarian cancer clinical risk prediction, therefore, seems unwarranted. Clin Cancer Res; 17(11); 3742-50. (C)2011 AACR.

AB Diabetic nephropathy is characterized by progressive mesangial expansion. Although we have reported that circulating oxidized LDL-containing immune complexes (oxLDL-IC) are associated with abnormal levels of albuminuria, the underlying mechanisms have not been investigated. In this study, we have studied the effect of oxLDL-IC on collagen IV expression by mesangial cells. We found that oxLDL-IC markedly stimulated collagen IV expression in a concentration- and time-dependent fashion while oxLDL only had moderate effect. We also found that oxLDL-IC stimulated collagen IV expression by engaging Fc gamma receptor (Fc gamma R) I and III, but not Fc gamma RII, and that p38 MAPK, JNK and PKC pathways were involved in collagen IV expression. Furthermore, we found that oxLDL-IC stimulated Fc gamma RI expression, suggesting a positive feedback mechanism involved in oxLDL-IC-stimulated collagen IV expression. Taken together, this study showed that oxLDL-IC stimulated collagen IV in mesangial cells via Fc gamma RI and Fc gamma RIII, and the expression of Fc gamma RI was increased by oxLDL-IC.

AB Glypican-3 is a promising target for immunotherapy for hepatocellular carcinoma, but limited data exist regarding its immunogenicity in patients with diverse HLA types, immunogenicity for CD4(+) T-cells, and the impact of inhibitory co-stimulation on glypican-3-specific T-cells. Using a 15mer overlapping peptide library for glypican-3, PBMC from patients with HCC were assessed ex vivo and after short-term in vitro expansion for tumor antigen-specific T-cell responses with and without blockade of PD-1/PD-L1 and CTLA-4 signaling. Glypican-3-specific T-cells were undetectable ex vivo, but primarily IFN gamma(+)TNF alpha(+) CD4(+) T-cells expanded with short-term in vitro stimulation in 10/19 (52%) patients. Glypican-3-specific CD8(+) T-cells predominantly produced TNF alpha, but did not secrete IFN gamma nor degranulate. CTLA-4 and PD-1 blockade minimally impacted the cytokine secretion and proliferation of glypican-3-specific T-cells. These data suggest that CD8(+). T-cell-directed tumor vaccines in HCC may have limited potential for efficacy unless optimal co-stimulation conditions can be identified but CD4(+)-directed vaccines merit consideration.

AB This study examined the relationship between rumination and the use of other emotion-regulation strategies in a depressed sample. Sixty outpatients diagnosed with unipolar depression completed questionnaires and participated in a sad mood induction. The mood induction was used to investigate the relationship between the use of rumination and each of two theoretically relevant emotion-regulation strategies-suppression and acceptance. Findings demonstrated that rumination was positively associated with other types of suppression and negatively related to acceptance. Results offer tentative support for the conceptualization of rumination as a maladaptive, cognitive emotion-regulation strategy utilized by depressed individuals in an attempt to suppress their experience of negative emotion. Findings also suggest a potential mechanism of action for efficacious mindfulness and acceptance-based treatments for depression.

AB OBJECTIVE-Metreleptin has been efficacious in improving metabolic control in patients with lipodystrophy, but its efficacy has not been tested in obese patients with type 2 diabetes.
RESEARCH DESIGN AND METHODS-We studied the role of leptin in regulating the endocrine adaptation to long-term caloric deprivation and weight loss in obese diabetic subjects over 16 weeks in the context of a double-blinded, placebo-controlled, randomized trial. We then performed detailed interventional and mechanistic signaling studies in humans in vivo, ex vivo, and in vitro.
RESULTS-In obese patients with diabetes, metreleptin administration for 16 weeks did not alter body weight or circulating inflammatory markers but reduced HbA(1c) marginally (8.01 +/- 0.93-7.96 +/- 1.12, P = 0.03). Total leptin, leptin-binding protein, and antileptin antibody levels increased, limiting free leptin availability and resulting in circulating free leptin levels of similar to 50 ng/mL. Consistent with clinical observations, all metreleptin signaling pathways studied in human adipose tissue and peripheral blood mononuclear cells were saturable at similar to 50 ng/mL, with no major differences in timing or magnitude of leptin-activated STAT3 phosphorylation in tissues from male versus female or obese versus lean humans in vivo, ex vivo, or in vitro. We also observed for the first time that endoplasmic reticulum (ER) stress in human primary adipocytes inhibits leptin signaling.
CONCLUSIONS-In obese patients with diabetes, metreleptin administration did not alter body weight or circulating inflammatory markers but reduced HbA(1c) marginally. ER stress and the saturable nature of leptin signaling pathways play a key role in the development of leptin tolerance in obese patients with diabetes. Diabetes 60:1647-1656, 2011

AB OBJECTIVE-Diabetes is an independent risk fact or for stroke. However, the underlying mechanism of how diabetes confers that this risk is not fully understood. We hypothesize that secretion of neurotrophic factors by the cerebral endothelium, such as brain-derived neurotrophic factor (BDNF), is suppressed in diabetes. Consequently, such accrued neuroprotective deficits make neurons more vulnerable to injury.
RESEARCH DESIGN AND METHODS-We examined BDNF protein levels in a streptozotocin-induced rat model of diabetes by Western blotting and immunohistochemistry. Levels of total and secreted BDNF protein were quantified in human brain microvascular endothelial cells after exposure to advanced glycation end product (AGE)-BSA by enzyme-linked immunosorbent assay and immunocytochemistry. In media transfer experiments, the neuroprotective efficacy of conditioned media from normal healthy endothelial cells was compared with AGE-treated endothelial cells in an in vitro hypoxic injury model.
RESULTS-Cerebrovascular BDNF protein was reduced in the cortical endothelium in 6-month diabetic rats. Immunohistochemical analysis of 6-week diabetic brain sections showed that the reduction of BDNF occurs early after induction of diabetes. Treatment of brain microvascular endothelial cells with AGE caused a similar reduction in BDNF protein and secretion in an extracellular signal-related kinase-dependent manner. In media transfer experiments, conditioned media from AGE-treated endothelial cells were less neuroprotective against hypoxic injury because of a decrease in secreted BDNF.
CONCLUSIONS-Taken together, our findings suggest that a progressive depletion of microvascular neuroprotection in diabetes elevates the risk of neuronal injury for a variety of central nervous system diseases, including stroke and neuro-degeneration. Diabetes 60:1789-1796, 2011

AB High-resolution magnetic resonance imaging (MRI) provides non-invasive images of retinal anatomy, physiology, and function with depth-resolved laminar resolution. Eye movement and drift, however, could limit high spatial resolution imaging, and anesthetics that minimize eye movement could significantly attenuate retinal function. The aim of this study was to determine the optimal anesthetic preparations to minimize eye movement and maximize visual-evoked retinal response in rats. Eye movements were examined by imaging of the cornea with a charge-coupled device (CCD) camera under isoflurane, urethane, ketamine/xylazine, and propofol anesthesia at typical dosages in rats. Combination of the paralytic pancuronium bromide with isoflurane or ketamine/xylazine anesthesia was also examined for the eye movement studies. Visual-evoked retinal responses were evaluated using full-field electroretinography (ERG) under isoflurane, ketamine/xylazine, urethane, and ketamine/xylazine + pancuronium anesthesia in rats. The degree of eye movement, measured as displacement per unit time, was the smallest under 1% isoflurane + pancuronium anesthesia. The ketamine/xylazine groups showed larger dark-adapted ERG a- and b-waves than other anesthetics tested. The isoflurane group showed the shortest b-wave implicit times. Photopic ERGs in the ketamine/xylazine groups showed the largest b-waves with the isoflurane group showing slightly shorter implicit times at the higher flash intensities. Oscillatory potentials revealed an early peak in the isoflurane group compared with ketamine/xylazine and urethane groups. Pancuronium did not affect the a- and b-wave, but did increase oscillatory potential amplitudes. Compared with the other anesthetics tested here, ketamine/xylazine + pancuronium was the best combination to minimize eye movement and maximize retinal function. These findings should set the stage for further development and application of high-resolution functional imaging techniques, such as MRI, to study retinal anatomy, physiology, and function in anesthetized rats.

AB Background: Gender aspects in medicine are receiving increasing attention, namely also in oncology. For this reason, we decided to investigate whether for solid cancer sites women have better survival outcome than do men in the population of Tyrol, Austria. Methods: We conducted an observational population-based study in Tyrol. All solid cancer sites excluding non-melanoma skin cancer and sex-specific sites were analysed in total and all specific sites with more than 500 patients in the analysis. By the end of 2006, follow-up was ended. We applied a relative excess risk model, thus correcting for differences in life expectancy between women and men. Results: For all cancer sites combined, after adjusting for case mix, women had a relative excess risk of 0.95 (95% CI 0.91-0.99). For the following sites our analysis resulted in a relative excess risk statistically different from 1, namely for women as compared to men: head and neck without larynx 0.72 (95% CI 0.56-0.93), stomach 0.86 (95% CI 0.75-0.97) and lung 0.82 (95% CI 0.75-0.90). Conclusion: In a healthcare system with free access to diagnostics and therapy, after adjusting for staging distribution female cancer patients have a lesser excess mortality risk than do men for lung, stomach and head and neck cancer and also for all cancer sites combined after adjusting for case mix.

TI Calcaneal Traction Pin Placement Simplified: A Cadaveric Study

ID ANATOMIC CONSIDERATIONS; ANKLE
AB Background: The tibial neurovascular bundle and sural nerve are at risk with errant pin placement during transcalcaneal pin placement. The purpose of this study was to determine a relative safe zone using a single osseous landmark to establish a technique applicable in the presence of trauma. We describe the neural anatomy anatomically and radiographically, giving surgeons a reliable and relatively safe technique for transcalcaneal pin placement. Materials and Methods: Twenty-four cadavers were dissected for the major medial neurovascular structures and the sural nerve. The closest distance from the neurovascular structures to the posterior inferior calcaneus was measured. Results: The mean distance from the posterior inferior calcaneus to the closest major medial neurovascular structure was 3.4 cm (SD +/- 0.36; range, 2.6 to 4.1 cm). The mean distance to the sural nerve was 3.4 cm (SD +/- 0.54; range, 2.3 to 4.6 cm). According to the 95% confidence intervals, a relative safe zone of 3.1 cm as a radius from the posterior inferior calcaneus was determined. Conclusion: A relatively safe zone of 3.1 cm based on 95% confidence intervals as described as a radius from the posterior inferior calcaneus can be used for transcalcaneal pin placement in most cases without injury to the medial neurovascular bundle or sural nerve. However anatomic variation may result in the neurovascular bundle being within this zone. Clinical Relevance: We describe a surgical technique for reliable placement of a transcalcaneal pin within this relative safe zone and a safe distance from the closest neurovascular structure.

AB Systemic lupus erythematosus (SLE) is a prototypic autoimmune disorder with a complex pathogenesis in which genetic, hormonal and environmental factors have a role. Rare mutations in the TREX1 gene, the major mammalian 3'-5' exonuclease, have been reported in sporadic SLE cases. Some of these mutations have also been identified in a rare pediatric neurological condition featuring an inflammatory encephalopathy known as Aicardi-Goutieres syndrome (AGS). We sought to investigate the frequency of these mutations in a large multi-ancestral cohort of SLE cases and controls. A total of 40 single-nucleotide polymorphisms (SNPs), including both common and rare variants, across the TREX1 gene, were evaluated in similar to 8370 patients with SLE and similar to 7490 control subjects. Stringent quality control procedures were applied, and principal components and admixture proportions were calculated to identify outliers for removal from analysis. Population-based case-control association analyses were performed. P-values, false-discovery rate q values, and odds ratios (OR) with 95% confidence intervals (CI) were calculated. The estimated frequency of TREX1 mutations in our lupus cohort was 0.5%. Five heterozygous mutations were detected at the Y305C polymorphism in European lupus cases but none were observed in European controls. Five African cases incurred heterozygous mutations at the E266G polymorphism and, again, none were observed in the African controls. A rare homozygous R114H mutation was identified in one Asian SLE patient, whereas all genotypes at this mutation in previous reports for SLE were heterozygous. Analysis of common TREX1 SNPs (minor allele frequency (MAF)>10%) revealed a relatively common risk haplotype in European SLE patients with neurological manifestations, especially seizures, with a frequency of 58% in lupus cases compared with 45% in normal controls (P = 0.0008, OR = 1.73, 95% CI = 1.25-2.39). Finally, the presence or absence of specific autoantibodies in certain populations produced significant genetic associations. For example, a strong association with anti-nRNP was observed in the European cohort at a coding synonymous variant rs56203834 (P = 2.99E-13, OR = 5.2, 95% CI = 3.18-8.56). Our data confirm and expand previous reports and provide additional support for the involvement of TREX1 in lupus pathogenesis.

AB Variants in the IMP2 (insulin-like growth factor 2 [IGF2] mRNA-binding protein 2) gene are implicated in susceptibility to type 2 diabetes. We describe the ability of mammalian target of rapamycin (mTOR) to regulate the cap-independent translation of IGF2 mRNA through phosphorylation of IMP2, an oncofetal RNA-binding protein. IMP2 is doubly phosphorylated in a rapamycin-inhibitable, amino acid-dependent manner in cells and by mTOR in vitro. Double phosphorylation promotes IMP2 binding to the IGF2 leader 3 mRNA 5' untranslated region, and the translational initiation of this mRNA through eIF-4E- and 5' cap-independent internal ribosomal entry. Unexpectedly, the interaction of IMP2 with mTOR complex 1 occurs through mTOR itself rather than through raptor. Whereas depletion of mTOR strongly inhibits IMP2 phosphorylation in cells, comparable depletion of raptor has no effect; moreover, the ability of mTOR to phosphorylate IMP2 in vitro is unaffected by the elimination of raptor. Dual phosphorylation of IMP2 at the mTOR sites is evident in the mouse embryo, likely coupling nutrient sufficiency to IGF2 expression and fetal growth. Doubly phosphorylated IMP2 is also widely expressed in adult tissues, including islets of Langerhans.

AB With rare exceptions, human tumors arise from single cells that have accumulated the necessary number and types of heritable alterations. Each such cell leads to dysregulated growth and eventually the formation of a tumor. Despite their monoclonal origin, at the time of diagnosis most tumors show a striking amount of intratumor heterogeneity in all measurable phenotypes; such heterogeneity has implications for diagnosis, treatment efficacy, and the identification of drug targets. An understanding of the extent and evolution of intratumor heterogeneity is therefore of direct clinical importance. In this article, we investigate the evolutionary dynamics of heterogeneity arising during exponential expansion of a tumor cell population, in which heritable alterations confer random fitness changes to cells. We obtain analytical estimates for the extent of heterogeneity and quantify the effects of system parameters on this tumor trait. Our work contributes to a mathematical understanding of intratumor heterogeneity and is also applicable to organisms like bacteria, agricultural pests, and other microbes.

AB Introduction. Carcinosarcoma of the ovary is a rare tumor with a grim prognosis. Chemotherapy for these tumors is chosen according to guidelines established for epithelial ovarian cancer (EOC). The purpose of this study is to compare response to chemotherapy and survival in patients with advanced stage carcinosarcoma of the ovary.
Methods. We identified women with advanced carcinosarcoma of the ovary who underwent first-line platinum and taxane-based chemotherapy. Each case was matched to two women with serous EOC. Cases and controls were matched by age, stage, and year of diagnosis. The Kaplan-Meier method was used to generate overall survival (OS) data. Factors predictive of outcome were compared using the log-rank test and Cox proportional hazards model.
Results. Fifty women treated with first line platinum and taxane-based chemotherapy had advanced carcinosarcoma of the ovary and were selected as cases. The response rates to chemotherapy for cases and controls were 62% and 83% (P = 0.03), respectively. Median progression-free survival was 11 months (95% CI, 8 to 14 months) versus 16 months (95% CI, 12 to 21 months; P = 0.02) and median overall survival was 24 months (95% CI, 18 to 29 months) versus 41 months (95% CI, 33 to 49 months; P = 0.002) for cases and controls, respectively.
Conclusion. Patients with advanced carcinosarcoma of the ovary have a poorer response to platinum and taxane-based first-line chemotherapy and worse survival, compared to patients with serous EOC. Aggressive surgical treatment may play an important role. However, other alternative systemic therapeutic approaches should be sought for patients with carcinosarcoma of the ovary.

AB Adaptive responses to sepsis are necessary to prevent organ failure and death. Cellular signaling responses that limit cell death and structural damage allow a cell to withstand insult from sepsis to prevent irreversible organ dysfunction. One such protective pathway to reduce hepatocellular injury is the up-regulation of heme oxygenase-1 (HO-1) signaling. HO-1 is up-regulated in the liver in response to multiple stressors, including sepsis and lipopolysaccharide (LPS), and has been shown to limit cell death. Another recently recognized rudimentary cellular response to injury is autophagy. The aim of these investigations was to test the hypothesis that HO-1 protects against hepatocyte cell death in experimental sepsis in vivo or LPS in vitro via induction of autophagy. These data demonstrate that both HO-1 and autophagy are up-regulated in the liver after cecal ligation and puncture (CLP) in C57BL/6 mice or in primary mouse hepatocytes after treatment with LPS (100 ng/mL). CLP or LPS results in minimal hepatocyte cell death. Pharmacological inhibition of HO-1 activity using tin protoporphyrin or knockdown of HO-1 prevents the induction of autophagic signaling in these models and results in increased hepatocellular injury, apoptosis, and death. Furthermore, inhibition of autophagy using 3-methyladenine or small interfering RNA specific to VPS34, a class III phosphoinositide 3-kinase that is an upstream regulator of autophagy, resulted in hepatocyte apoptosis in vivo or in vitro. LPS induced phosphorylation of p38 mitogen-activated protein kinase (p38 MAPK), in part, via HO-dependent signaling. Moreover, inhibition of p38 MAPK prevented CLP- or LPS-induced autophagy. Conclusion: Sepsis or LPS-induced autophagy protects against hepatocellular death, in part via an HO-1 p38 MAPK-dependent signaling. Further investigations are needed to elucidate how autophagic signaling prevents apoptosis and cell death. (HEPATOLOGY 2011;53:2053-2062)

AB Symptomatic abnormal periprosthetic soft-tissue reactions ("pseudotumors") have been reported after metal-on-metal hip resurfacing arthroplasty (MoMHRA). The aims of this study were (1) to determine the prevalence of asymptomatic pseudotumors after MoMHRA and (2) to measure metal ion levels in these patients. A total of 201 hips in 158 patients were evaluated at a mean follow-up of 61 months (range, 36-88) using ultrasound/magnetic resonance imaging and serum/hip aspirate cobalt and chromium measurements. Pseudotumors found in 7 patients (4%) were associated with significantly higher cobalt and chromium levels and inferior functional scores. Elevated levels of cobalt and chromium ions suggest that pseudotumors are associated with increased wear generated from metal-on-metal articulations. Clinicians need to be aware of pseudotumors as a differential diagnosis during clinical evaluation of MoMHRA patients, and further imaging such as ultrasound or magnetic resonance imaging is recommended to confirm the diagnosis.

AB We identified 128 revision total hip arthroplasties from 1993 to 2005 involving a well-fixed Harris-Galante Porous (HGP)-I or HGP-II acetabular component with minimum 2-year post-revision follow-up. Three treatment cohorts were identified. Of the hips that underwent modular liner exchange at revision, 14 hips (25%) required re-revision of the acetabular component, 8 for liner dislodgement, 3 for osteolysis and poly-wear, 2 for dislocation, and 1 for aseptic loosening. Of the hips that underwent revision of the well-fixed shell, 4 (15%) required subsequent re-revision of the acetabular component; 2 for dislocation and 2 for aseptic loosening. Six hips (27%) in the cemented liner group were re-revised; 4 for dislocation and 2 for loosening. Complete revision of a well-fixed HGP acetabular component is more reliable than liner exchange or liner cementation.

AB Doppler optical coherence tomography (DOCT) and OCT angiography are novel methods to investigate cerebrovascular physiology. In the rodent cortex, DOCT flow displays features characteristic of cerebral blood flow, including conservation along nonbranching vascular segments and at branch points. Moreover, DOCT flow values correlate with hydrogen clearance flow values when both are measured simultaneously. These data validate DOCT as a noninvasive quantitative method to measure tissue perfusion over a physiologic range.

AB Arterial spin labeling (ASL) and dynamic susceptibility contrast (DSC) magnetic resonance imaging (MRI) are widely used to image cerebral blood flow (CBF) in stroke. This study examined how changes in tissue spin-lattice relaxation-time constant (T(1)), blood-brain barrier (BBB) permeability, and transit time affect CBF quantification by ASL and DSC in postischemic hyperperfusion in the same animals. In Group I (n = 6), embolic stroke rats imaged 48 hours after stroke showed regional hyperperfusion. In normal pixels, ASL- and DSC-CBF linearly correlated pixel-by-pixel. In hyperperfusion pixels, ASL-CBF was significantly higher than DSC-CBF pixel-by-pixel (by 25%). T1 increased from 1.76 +/- 0.14 seconds in normal pixels to 1.93 +/- 0.17 seconds in hyperperfusion pixels. Arterial transit time decreased from 300 milliseconds in normal pixels to 200 milliseconds in hyperperfusion pixels. Delta R(2)* profiles showed contrast-agent leakages in the hyperperfusion regions. In Group II (n = 3) in which hypercapnic inhalation was used to increase CBF without BBB disruption, CBF increased overall but ASL- and DSC-CBF remained linearly correlated. In Group III (n = 3) in which mannitol was used to break the BBB, ASL-CBF was significantly higher than DSC-CBF. We concluded that in normal tissue, ASL and DSC provide comparable quantitative CBF, whereas in postischemic hyperperfusion, ASL-CBF and DSC-CBF differed significantly because ischemia-induced changes in T1 and BBB permeability affected the two methods differently.

AB Clinicians are often uncertain about how to manage elevated blood pressure (BP) when a patient reports that he/she has recently missed several doses of antihypertensive medications. While we know that better adherence can improve BP during several months, the magnitude of this relationship in the short term is poorly understood. The authors examined this issue using a group of patients who monitored adherence using a Medication Events Monitoring System (MEMS) cap and had BP measurements in the course of routine clinical practice. BP readings were compared following 7 days of excellent adherence (100%) or poor adherence (< 60%), omitting BP values following intermediate adherence. Using several different methods, BP following 7 days of excellent adherence was between 12/7 mm Hg and 15/8 mm Hg lower than after 7 days of poor adherence. Clinicians can use this effect size to calibrate their impressions of what the BP might have been with improved adherence. J Clin Hypertens (Greenwich). 2011;13:416-421.

AB The continued spread of the HIV epidemic underscores the need to interrupt transmission. One attractive strategy is a topical vaginal microbicide. Sexual transmission of herpes simplex virus type 2 (HSV-2) in mice can be inhibited by intravaginal siRNA application. To overcome the challenges of knocking down gene expression in immune cells susceptible to HIV infection, we used chimeric RNAs composed of an aptamer fused to an siRNA for targeted gene knockdown in cells bearing an aptamer-binding receptor. Here, we showed that CD4 aptamer-siRNA chimeras (CD4-AsiCs) specifically suppress gene expression in CD4(+) T cells and macrophages in vitro, in polarized cervicovaginal tissue explants, and in the female genital tract of humanized mice. CD4-AsiCs do not activate lymphocytes or stimulate innate immunity. CD4-AsiCs that knock down HIV genes and/or CCR5 inhibited HIV infection in vitro and in tissue explants. When applied intravaginally to humanized mice, CD4-AsiCs protected against HIV vaginal transmission. Thus, CD4-AsiCs could be used as the active ingredient of a microbicide to prevent HIV sexual transmission.

AB Lung cancer is the leading cause of cancer death worldwide. Both principal factors known to cause lung cancer, cigarette smoke and asbestos, induce pulmonary inflammation, and pulmonary inflammation has recently been implicated in several murine models of lung cancer. To further investigate the role of inflammation in the development of lung cancer, we generated mice with combined loss of IFN-gamma and the beta-common cytokines GM-CSF and IL-3. These immunodeficient mice develop chronic pulmonary inflammation and lung tumors at a high frequency. Examination of the relationship between these tumors and their inflammatory microenvironment revealed a dual role for the immune system in tumor development. The inflammatory cytokine IL-6 promoted optimal tumor growth, yet wild-type mice rejected transplanted tumors through the induction of adaptive immunity. These findings suggest a model whereby cytokine deficiency leads to oncogenic inflammation that combines with defective antitumor immunity to promote lung tumor formation, representing a unique system for studying the role of the immune system in lung tumor development.

AB Most degenerative diseases begin with a gradual loss of specific cell types before reaching a threshold for symptomatic onset. However, the endogenous regenerative capacities of different tissues are difficult to study, because of the limitations of models for early stages of cell loss. Therefore, we generated a transgenic mouse line (Mos-iCsp3) in which a lox-mismatched Cre/lox cassette can be activated to produce a drug-regulated dimerizable caspase-3. Tissue-restricted Cre expression yielded stochastic Casp3 expression, randomly ablating a subset of specific cell types in a defined domain. The limited and mosaic cell loss led to distinct responses in 3 different tissues targeted using respective Cre mice: reversible, impaired glucose tolerance with normoglycemia in pancreatic beta cells; wound healing and irreversible hair loss in the skin; and permanent moderate deafness due to the loss of auditory hair cells in the inner ear. These mice will be important for assessing the repair capacities of tissues and the potential effectiveness of new regenerative therapies.

AB Induction of virus-specific CD8(+) T cell responses is critical for the success of vaccines against chronic viral infections. Despite the large number of potential MHC-I-restricted epitopes located in viral proteins, MHC-I-restricted epitope generation is inefficient, and factors defining the production and presentation of MHC-I-restricted viral epitopes are poorly understood. Here, we have demonstrated that the half-lives of HIV-derived peptides in cytosol from primary human cells were highly variable and sequence dependent, and significantly affected the efficiency of cell recognition by CD8(+) T cells. Furthermore, multiple clinical isolates of HLA-associated HIV epitope variants displayed reduced half-lives relative to consensus sequence. This decreased cytosolic peptide stability diminished epitope presentation and CTL recognition, illustrating a mechanism of immune escape. Chaperone complexes including Hsp90 and histone deacetylase HDAC6 enhanced peptide stability by transient protection from peptidase degradation. Based on empirical results with 166 peptides, we developed a computational approach utilizing a sequence-based algorithm to estimate the cytosolic stability of antigenic peptides. Our results identify sequence motifs able to alter the amount of peptide available for loading onto MHC-I, suggesting potential new strategies to modulate epitope production from vaccine immunogens.

AB C57BL/6J and 129S6/Sv (B6 and 129) mice differ dramatically in their susceptibility to developing diabetes in response to diet- or genetically induced insulin resistance. A major locus contributing to this difference has been mapped to a region on mouse chromosome 14 that contains the gene encoding PKC delta. Here, we found that PKC delta expression in liver was 2-fold higher in B6 versus 129 mice from birth and was further increased in B6 but not 129 mice in response to a high-fat diet. PRKCD gene expression was also elevated in obese humans and was positively correlated with fasting glucose and circulating triglycerides. Mice with global or liver-specific inactivation of the Prkcd gene displayed increased hepatic insulin signaling and reduced expression of gluconeogenic and lipogenic enzymes. This resulted in increased insulin-induced suppression of hepatic gluconeogenesis, improved glucose tolerance, and reduced hepatosteatosis with aging. Conversely, mice with liver-specific overexpression of PKC delta developed hepatic insulin resistance characterized by decreased insulin signaling, enhanced lipogenic gene expression, and hepatosteatosis. Therefore, changes in the expression and regulation of PKC delta between strains of mice and in obese humans play an important role in the genetic risk of hepatic insulin resistance, glucose intolerance, and hepatosteatosis; and thus PKC delta may be a potential target in the treatment of metabolic syndrome.

Seminested PCR targeting Mucorales 18S ribosomal DNA and sequencing were performed on formalin-fixed paraffin-embedded tissue samples. Of 29 cases of mucormycosis, 27 had tissue samples available for PCR and sequencing. Mucorales PCR was positive in 22. Among 12 culture-positive cases, 10 were PCR positive and sequencing was concordant with culture results to the genus level in 9. Among 15 culture-negative cases, PCR was positive and sequencing allowed genus identification in 12. Mucorales PCR is useful for confirmation of the diagnosis of mucormycosis and for further characterization of the infection in cases where cultures are negative.

AB NK cells have been increasingly reported to be an important effector in autoimmune diseases. However, nothing is known in this regard in DED, the most common eye pathology, which is characterized by sustained inflammation on the ocular surface. In the present study, we have examined the profile of NK cells on the ocular surface as well as in the draining lymphoid tissues during the development of this disease. Our data demonstrate activated NK cells during the disease-induction phase. Moreover, in vivo depletion of NK cells in mice results in reduced disease severity and diminished proinflammatory cytokines. Furthermore, we show that NK cells are also able to modulate the maturation of APCs, which is correlated with IFN-gamma from NK cells. Together, our findings provide new in vivo evidence that IFN-gamma-secreting NK cells can promote induction of DED via direct target tissue damage and indirect influence on the priming phase of an adaptive immune response in secondary lymphoid tissue.

AB Purpose: To measure the impact of corrupted images often found to occur in diffusion-weighted magnetic resonance imaging (DW-MRI). To propose a robust method for the correction of outliers, applicable to diffusion tensor imaging (DTI) and q-ball imaging (QBI).
Materials and Methods: Monte Carlo simulations were carried out to measure the impact of outliers on DTI and QBI reconstruction in a single voxel. Methods to correct outliers based on q-space interpolation and direction removal were then implemented and validated in real image data.
Results: Corruption in a single voxel led to clear variations in DTI and QBI metrics. In real data, the method of q-space interpolation was successful in identifying corrupted voxels and restoring them to values consistent with those of uncorrupted images.
Conclusion: For images containing few gradient directions, where outlier removal was either impossible due to limited volumes or resulted in large changes in DTI/QBI metrics, q-space interpolation proved to be the method of choice for image restoration. A simple decision support system is proposed to assist clinicians in the correction of their corrupted DW data.

AB Purpose: To evaluate the reduced transverse relaxation rate (RR2), a new relaxation index which has been shown recently to be primarily sensitive to intracellular ferritin iron, as a means of detecting short-term changes in myocardial storage iron produced by iron-chelating therapy in transfusion-dependent thalassemia patients.
Materials and Methods: A single-breathhold multi-echo fast spin-echo sequence was implemented at 3 Tesla (T) to estimate RR2 by acquiring signal decays with interecho times of 5, 9 and 13 ms. Transfusion-dependent thalassemia patients (N = 8) were examined immediately before suspending iron-chelating therapy for 1 week (Day 0), after a 1-week suspension of chelation (Day 7), and after a 1-week resumption of chelation (Day 14).
Results: The mean percent changes in RR2, R2, and R2* off chelation (between Day 0 and 7) were 11.9 +/- 8.9%, 5.4 +/- 7.7% and -4.4 +/- 25.0%; and, after resuming chelation (between Day 7 and 14), -10.6 +/- 13.9%, -8.9 +/- 8.0% and -8.5 +/- 24.3%, respectively. Significant differences in R2 and RR2 were observed between Day 0 and 7, and between Day 7 and 14, with the greatest proportional changes in RR2. No significant differences in R2* were found.
Conclusion: These initial results demonstrate that significant differences in RR2 are detectable after a single week of changes in iron-chelating therapy, likely as a result of superior sensitivity to soluble ferritin iron, which is in close equilibrium with the chelatable cytosolic iron pool. RR2 measurement may provide a new means of monitoring the short-term effectiveness of iron-chelating agents in patients with myocardial iron overload.

AB Phosphoinositide 3-kinase enhancer (PIKE) binds and enhances phosphatidylinositol 3-kinase (PI3K)/Akt activities. However, its physiological functions in brain have never been explored. Here we show that PIKE is important in regulating the neuronal survival and development of neocortex. During development, enhanced apoptosis is observed in the ventricular zone of PIKE knock-out (PIKE(-/-)) cortex. Moreover, PIKE(-/-) neurons show reduced dendritic complexity, dendritic branch length, and soma size. These defects are due to the reduced PI3K/Akt activities in PIKE(-/-) neurons, as the impaired dendritic arborization can be rescued when PI3K/Akt cascade is augmented in vitro or in PIKE(-/-) PTEN(-/-) double-knock-out mice. Interestingly, PIKE(-/-) mice display behavioral abnormality in locomotion and spatial navigation. Because of the diminished PI3K/Akt activities, PIKE(-/-) neurons are more vulnerable to glutamate- or stroke-induced neuronal cell death. Together, our data established the critical role of PIKE in regulating neuronal survival and development by substantiating the PI3K/Akt pathway.

AB Research in recent decades has suggested the existence of a dedicated brain network devoted to the organization and execution of grasping, one of the most important and skilled movements of primates. Grasping an object requires the transformation of intrinsic object properties such as size, orientation, and shape into an appropriate motor scheme shaping the hand. Although electrophysiological recordings in the monkey model have proven invaluable for gaining insights into the neuronal substrate underlying this complex behavior, knowledge concerning the existence and organization of a similar system in the human brain is derived mainly from imaging studies. Here, we present for the first time functional magnetic resonance imaging (fMRI) of brain activity while macaque monkeys performed reaching and grasping movements in a 3 tesla MR scanner. Grasping in the dark (compared with reaching) yielded significant activations in anterior intraparietal area and ventral premotor area F5, in addition to area PFG in the rostral inferior parietal lobule, somatosensory areas (SI, SII, area 5), and the hand field of F1. Whole-brain macaque fMRI motor studies will be instrumental in establishing possible homologies concerning grasping organization in the human and monkey brains, bridging the gap between human imaging and monkey electrophysiology.

AB Object. In patients with medically refractory epilepsy the accurate localization of the seizure onset zone is critical for successful surgical treatment. The object of this study was to investigate whether the degree of coupling of spontaneous brain activity as measured with functional connectivity MR imaging (fcMR imaging) can accurately identify and localize epileptic discharges.
Methods. The authors studied 6 patients who underwent fcMR imaging presurgical mapping and subsequently underwent invasive electroencephalography.
Results. Focal regions of statistically significant increases in connectivity were identified in 5 patients when compared with an ad hoc normative sample of 300 controls. The foci identified by fcMR imaging overlapped the epileptogenic areas identified by in encephalography in all 5 patients.
Conclusions. These results suggest that fcMR imaging may provide an effective high spatial resolution and noninvasive method of localizing epileptic discharges in patients with refractory epilepsy. (DOI: 10.3171/2011.1.JNS10482)

AB Object. The authors evaluated the prognostic significance of blood glucose level at admission (BOA) and change in blood glucose at 48 hours from the baseline value (CG48) in nondiabetic and diabetic patients before and after endovascular therapy for acute ischemie stroke (AIS).
Methods. The BOA and CG48 data were analyzed in 614 patients with AIS who received endovascular therapy at 7 US centers between 2006 and 2009. Data reviewed included demographics, stroke risk factors, diabetic status. National Institutes of Health Stroke Scale (NIHSS) score at presentation. recanalization grade. intracranial hemorrhage (ICH) rate, and 90-day outcomes (mortality rate and modified Rankin Scale score of 3-6 [defined as poor outcome]). Variables with p values < 0.2 in univariate analysis were included in a binary logistic regression model for independent predictors of 90-day outcomes.
Results. The mean patient age was 67.3 years. the median NIHSS score was 16, and 27% of patients had diabetes. In nondiabetic patients. BGA >= 116 mg/dl (>= 6.4 mmol/L) and failure of glucose level to drop > 30 mg/dl (> 1.7 mmol/L) from the admission value were both significant predictors of 90-day poor outcome and death (p < 0.001). In patients with diabetes. BGA >= 116 mg/dl (>= 6.4 mmol/L) was an independent predictor of poor outcome (p = 0.001). The CG48 was not a predictor of outcome in diabetic patients. A simplified 6-point scale including BGA. Thrombolysis in Myocardial Infarction (TIMI) Grade 2-3 Reperfusion. Age. presentation NIHSS score, CG48. and symptomatic ICH (BRANCH) corresponded with poor outcomes at 90 days: the area under the curve value was > 0.79.
Conclusions. Failure of blood glucose values to decrease in the first 48 hours after AIS intervention correlated with poor 90-day outcomes in nondiabetic patients. The BRANCH scale shows promise as a simple prognostication tool after endovascular therapy for AIS. and it merits prospective validation. (DOI: 10.3171/2011.LINS10884)

TI Vertebral artery pexy for microvascular decompression of the facial
nerve in the treatment of hemifacial spasm
SO JOURNAL OF NEUROSURGERY

brainstem; facial nerve; cranial nerve VII; pledget
ID TRIGEMINAL NEURALGIA; TECHNICAL NOTE; COMPRESSION; PATTERNS
AB Object. Hemi facial spasm (HFS) is caused by arterial or venous compression of cranial nerve VII at its root exit zone. Traditionally, microvascular decompression of the facial nerve has been an effective treatment for posterior inferior and anterior inferior cerebellar artery as well as venous compression. The traditional technique involves Teflon felt or another construct to cushion the offending vessel from the facial nerve, or cautery and division of the offending vein. However, using this technique for severe vertebral artery (VA) compression can he ineffective and fraught with complications. The authors report the use of a new technique of VA pexy to the petrous or clival dura mater in patients with HFS attributed to a severely ectatic and tortuous VA. and detail the results in a series of patients.
Methods. Six patients with I-IFS due to VA compression underwent a retrosigmoid craniotomy. combined with a far-lateral approach in some patients. On identification of the site of VA compression. the vessel was mobilized adequately for the decompression. Great care was taken to avoid kinking the perforating vessels arising from the VA. Two 8-0 nylon sutures were passed through to the wall of the VA and then through the diva! or petrous dura, and then tied to alleviate compression on cranial nerve VII.
Results. Patients were followed for at least 1 year postoperatively (mean 2.7 years. range 1 4 years). All 6 patients had complete resolution of their HFS. Facial function was tested postoperatively. and was stable when compared with the preoperative baseline. Two of the 3 patients with preoperative Minims had resolution of this symptom after the procedure. Postoperative imaging demonstrated VA decompression of the facial nerve and no evidence of stroke in all patients. One patient suffered from hearing loss, another developed a postoperative transient unilateral vocal cord paralysis, and a third patient developed a pseudomeningocele that resolved with the placement of a lumbar drain.
Conclusions. Hemifacial spasm and other neurovascular syndromes are effectively treated by repositioning the compressing artery. Careful study of the preoperative MR images may identify a select group of patients with I-IFS due to an ectatic VA. Rather than traditional decompression with only pledget placement, these patients may be from a VA pexy to provide an effective. safe. and durable resolution of their symptoms while minimizing surgical complications.

AB Purpose: The purpose of this study was to better understand neck intermuscular beta coherence (15-35 Hz; NIBcoh) in healthy individuals, with respect to modulation by behavioral tasks.
Method: Mean NIBcoh was measured using surface electromyography at 2 anterior neck locations in 10 individuals during normal speech, static nonspeech maneuvers, "clear" speech (intentionally produced to maximize intelligibility), divided-attention speech, singing, and mimicked hyperfunctional speech.
Results: An analysis of variance showed significant effects of both individual and condition (p = .001) on the mean beta-band intermuscular coherence. Dunnett's simultaneous paired t tests found decreased NIBcoh during low-attention speech, singing, and hyperfunctional speech (padj < .05), but no significant difference in NIBcoh during nonspeech tasks or clear speech production relative to normal speech.
Conclusions: Compared with normal speech, mean NIBcoh was decreased in a divided-attention speech task, but clear speech did not result in increased mean coherence relative to normal speech, possibly due to ceiling effects caused by heightened attention and precision during experimental recording. Mimicking a strained, hyperfunctional voice resulted in a reduction in mean beta intermuscular coherence quantitatively and qualitatively similar to the lowered values of mean beta coherence seen in individuals with vocal nodules relative to individuals with normal voice.

AB Objective: High rates of substance-use disorders (SUD) have been found in samples of adolescents and adults with attention-deficit/hyperactivity disorder (ADHD). Predictors of SUD in children with ADHD who are at risk for the development of SUDs remain understudied. The main aims of this study were to identify clinically meaningful characteristics of children that predicted the future development of SUDs and to see whether the role of these characteristics varied by sex. Method: Subjects were children and adolescents with (n = 268; mean age +/- standard deviation = 10.9 +/- 3.2 years) and without (n = 229; mean age 11.9 +/- 3.3 years) DSM-III-R ADHD followed prospectively and blindly over a 10-year follow-up period onto young adult years. Subjects were assessed with structured diagnostic interviews for psychopathology and SUDs. Results: Over the 10-year follow-up period, ADHD was found to be a significant predictor of any SUD (hazards ratio 1.47; 95% confidence interval 1.07-2.02; p = .01) and cigarette smoking (2.38; 1.61-3.53; p < .01). Within ADHD, comorbid conduct disorder (2.74; 1.66-4.52; p < .01) and oppositional defiant disorder (2.21; 1.40-3.51; p < .01) at baseline were also found to be significant predictors of SUDs. Similar results were found for cigarette-, alcohol-, and drug-use disorders. There were few meaningful sex interaction effects. No clinically significant associations were found for any social or family environment factors or for cognitive functioning factors (p > .05 for all comparisons). Conclusions: These results indicate that ADHD is a significant risk factor for the development of SUDs and cigarette smoking in both sexes. J. Am. Acad. Child Adolesc. Psychiatry, 2011;50(6):543-553.

AB Background: The incidence of cutaneous squamous cell carcinoma (cSCC) is increasing. Although most patients achieve complete remission with surgical treatment, those with advanced disease have a poor prognosis. The American Joint Committee on Cancer (AJCC) is responsible for the staging criteria for all cancers. For the past 20 years, the AJCC cancer staging manual has grouped all nonmelanoma skin cancers, including cSCC, together for the purposes of staging. However, based on new evidence, the AJCC has determined that cSCC should have a separate staging system in the 7th edition AJCC staging manual.
Objective: We sought to present the rationale for and characteristics of the new AJCC staging system specific to cSCC tumor characteristics (T).
Methods: The Nonmelanoma Skin Cancer Task Force of AJCC reviewed relevant data and reached expert consensus in creating the 7th edition AJCC staging system for cSCC. Emphasis was placed on prospectively accumulated data and multivariate analyses. Concordance with head and neck cancer staging system was also achieved.
Results: A new AJCC cSCC T classification is presented. The T classification is determined by tumor diameter, invasion into cranial bone, and high-risk features, including anatomic location, tumor thickness and level, differentiation, and perineural invasion.
Limitations: The data available for analysis are still suboptimal, with limited prospective outcomes trials and few multivariate analyses.
Conclusions: The new AJCC staging system for cSCC incorporates tumor-specific (T) staging features and will encourage coordinated, consistent collection of data that will be the basis of improved prognostic systems in the future. (J Am Acad Dermatol 2011;64:1051-9.)

AB Background: As melanoma rates increase, and the supply of dermatologists remains suboptimal to meet demand for services, detection of early melanoma has become an increasingly difficult challenge. Some authors advocate for shifting dermatologic resources from routine appointments to urgent visits for those With lesions concerning for melanoma.
Objective: We sought to investigate the potential of an urgent access track (UAT) embedded within a pigmented lesion clinic to improve early melanoma detection.
Methods: We conducted a retrospective review of patient records from a tertiary care hospital's pigmented lesion clinic and the associated UAT.
Results of procedures for all 4495 patient visits to the routine track and all 316 visits to the UAT during the 21-month study period were included, as were detailed chart reviews of all UAT patient visits. Results: UAT visits were more than 4 times as likely (4.1% vs 1.0%) to yield a diagnosis of melanoma as routine track visits (odds ratio 4.24; 95% confidence interval 2.28-7.88; P < .0001), and almost 25 times as likely (2.2% vs 0.1%) to yield a diagnosis of metastatic melanoma (odds ratio 25.4; 95% confidence interval 7.4-87.4; P < .0001).
Limitations: This was a preliminary analysis with only limited data extracted from the routine track pigmented lesion clinic patient visits.
Conclusion: This initial analysis of UAT strategy suggests that UATs have potential to detect patients with earlier melanomas; further research is needed to specifically delineate how resources should be best allocated between routine surveillance and urgent care to maximize melanoma early detection and survival.

ID Q-SWITCHED RUBY; ND-YAG LASER; DOSE-RESPONSE; NM; PHOTOTHERMOLYSIS
AB Background: Q-switched lasers are the gold standard for tattoo treatment. Allergic tattoo reactions present a treatment dilemma. We present the application of ablative fractional resurfacing (AFR) as a novel method for tattoo removal.
Objective: We describe two patients with tattoo allergies, referred to us for treatment.
Methods: AFR was used in a series of treatments to remove the allergic-ink portion of a multicolored tattoo on the upper extremity of a 52-year-old man. In a 31-year-old woman with a red and black tattoo on her lower extremity, AFR was combined with a Q-switched neodymium:yttrium-aluminum-garnet laser.
Results: After a series of treatments, both patients experienced significant to complete removal of the offending tattoo inks with substantial or complete resolution of their symptoms.
Limitations: This uncontrolled observational series is based on two patients.
Conclusions: AFR appears to be safe and effective for removal of allergic tattoos. AFR can be combined with other treatments such as Q-switched lasers. The potential for a series of AFR treatments to remove tattoos, including allergic tattoos and inks of any color, merits further study. (J Am Acad Dermatol 201164:1111-4.)

AB Modifications in implant design and improvements in surgical technique have expanded the applications of total elbow arthroplasty. Complications associated with reconstructive elbow surgery persist, however, often leading to profound and sometimes nonsalvageable disability. The most recognized complications include implant loosening, periprosthetic fracture, implant failure, infection, triceps insufficiency, and nerve palsy. Although far fewer elbow arthroplasties than lower extremity arthroplasties are performed, the proportion of complications is greater with elbow arthroplasty, and the outcomes of secondary reconstruction are less favorable.

AB Cognitive processing therapy (CPT) for posttraumatic stress disorder (PTSD) has been shown to reduce symptoms of PTSD in a veteran population. This study explored patterns of self-reported symptom change during CPT. Veterans (N = 60) with PTSD were randomized to receive CPT immediately or after 10 weeks. We hypothesized that those treated immediately would evidence initial symptom stability followed by decline compared with those who waited, whose PTSD symptoms would remain stable. The best model fit based on deviance statistics and Bayesian information criteria comparisons was one in which participants treated immediately showed more rapid initial decline followed by a slower rate of PTSD symptom improvement relative to those who waited, who showed a stable level of symptomatology. Findings suggest that CPT produces quick and maintained improvements in veterans. The effect sizes for change between those who received CPT immediately and those who waited were approximately medium sized. Implications of findings are discussed.

AB Military chaplains are invaluable caregiver resources for service members. Little is known about how chaplains respond to the challenge of providing spiritual counsel in a warzone. In this exploratory study, 183 previously deployed Air Force chaplains completed an online survey assessing operational and counseling stress exposure, posttraumatic stress disorder (PTSD) symptoms, compassion fatigue, and posttraumatic growth. Despite reporting exposure to stressful counseling experiences, Air Force chaplains did not endorse high compassion fatigue. Rather, chaplains experienced positive psychological growth following exposure to stressful counseling experiences. However, 7.7% of Air Force chaplains reported clinically significant PTSD symptoms, suggesting that they are not immune to deployment-related mental health problems. Simultaneous regression analyses revealed that counseling stress exposure predicted compassion fatigue (beta = .20) and posttraumatic growth (beta = .24), suggesting that caretaking in theatre is stressful enough to spur positive psychological growth in chaplains. Consistent with findings from previous studies, hierarchical regression analyses revealed that operational stress exposure predicted PTSD symptom severity (beta = .33) while controlling for demographic variables.

AB Despite interest in the nature of the traumatic event required to meet Criterion A for posttraumatic stress disorder (PTSD) as defined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV; American Psychiatric Association, 1994), little attention has been paid to the diagnostic ramifications of linking PTSD symptoms to a single traumatic event in the context of multiple trauma exposures. In this study, 67 dually diagnosed clients with at least 2 potential Criterion A traumatic events completed the Posttraumatic Stress Diagnostic Scale twice, in counterbalanced order: once regarding their worst event and once regarding all events. When responding regarding their worst trauma, 53.7% met probable PTSD criteria. This rose to 67.2% when considering all traumas. Although preliminary, these results suggest that linking PTSD symptoms to a single traumatic event excludes a meaningful number of cases who are otherwise indistinguishable based on symptom profile.

AB Meaningful progress in our understanding and clinical approach to primary angiitis of the CNS (PACNS) has been made in the past three decades. Increased recognition of PACNS and general advances in diagnosis of neurological disorders have led to an aggressive diagnostic approach and a proliferation of case reports providing enriched clinical and pathological descriptions. We have witnessed major advances not only in the diagnosis of PACNS but in the recognition of its mimics. Epidemiological, clinical, neuroradiagnostic, and laboratory findings have enhanced our diagnostic accuracy and recognition of PACNS mimics, however, many challenges to our understanding and management of the disease in children and adults remain.

AB Objectives: To bond vocal fold flaps using a sutureless, nonthermal laser-assisted method combining visible light and photosensitizing dyes to produce collagen crosslinks.
Study Design: In the ex vivo study, epithelial incisions were created in sheep vocal folds. The concentration of the Rose Bengal, and the laser fluence were varied and studied. The in vivo canine study evaluated the thickness of the basement membrane zone, density and distribution of collagen, elastin, and fibroblasts at time zero, 2 weeks, and 8 weeks.
Methods: Ex Vivo: Rose Bengal at concentrations between 0.5% and 1.0% was applied to the free margins of the incision and irradiated with an Nd:YAG laser at fluences varying from 150 to 600 J/cm(2). The bonding was considered positive when the incision could withstand air at 2 pounds per square inch (psi) from a distance of 3 cm. In Vivo: 0.75% Rose Bengal was applied to the microflap edges and irradiated with an Nd: YAG laser for 140 seconds (100 J/cm(2)). The control side was not irradiated.
Results: Ex Vivo: Bonding was achieved with a minimum of 0.75% Rose Bengal and 300 J/cm(2). In Vivo: There was no difference in the amount of subepithelial reaction between the experimental and control sides at 8 weeks.
Conclusions: Photochemical tissue bonding is effective at sealing vocal fold incisions and did not create long-term scarring of the vocal folds. Use of this technique may allow for more predictable healing after microflap resection and may reduce the need for postoperative voice rest.

AB Non-human primates are often used as preclinical model systems for (mostly diffuse or multi-focal) neurological disorders and their experimental treatment. Due to cost considerations, such studies frequently utilize non-destructive imaging modalities, MRI and proton MR spectroscopy ((1)H MRS). Cost may explain why the inter-and intra-animal reproducibility of the (1)H MRS observed brain metabolites, are not reported. To this end, we performed test-retest three-dimensional brain (1)H MRS in five healthy rhesus macaques at 3 T. Spectra were acquired from 224 isotropic (0.5 cm)(3) 5 125 mu L voxels, over 28 cm(3) (similar to 35%) of the brain, then individually phased, frequency aligned and summed into a spectrum representative of the entire volume of interest. This dramatically increases the metabolites' signal-to-noise ratios, while maintaining the (narrow) voxel linewidth. The results show that the average N-acetylaspartate, creatine, choline, and myo-inositol concentrations in the macaque brain are: 7.7 +/- 0.5, 7.0 +/- 0.5, 1.2 +/- 0.1 and 4.0 +/- 0.6 mM/g wet weight (mean +/- standard deviation). Their inter-animal coefficients of variation (CV) are 4%, 4%, 6%, and 15%; and the longitudinal (intra-animal) CVs are lower still: 4%, 5%, 5%, and 4%, much better than the 22%, 33%, 36%, and 45% intra-voxel CVs, demonstrating the advantage of the approach and its utility for preclinical studies of diffuse neurological diseases in rhesus macaques.

AB This study reports a high-resolution MRI approach to image basal blood flow and hypercapnia-induced blood-flow changes in the unanesthetized human retina on a 3-T MRI scanner. Pseudo-continuous arterial spin labeling technique with static tissue suppression was implemented to minimize movement artifacts and improve blood-flow sensitivity. Turbo spin-echo acquisition was used to achieve high spatial resolution free of susceptibility artifacts. The size, shape, and position of a custom-made receive radiofrequency coil were optimized for sensitivity in the posterior retina. Synchronized eye blink and respiration to the end of each data readout minimized eye movement and physiological fluctuation. Robust high-contrast blood-flow MRI of the unanesthetized human retina was obtained at 500 X 800 mu m(2) in-plane resolution. Blood flow in the posterior retina was 93 +/- 31 mL/(100 mL min) (mean +/- standard deviation, N = 5). Hypercapnic inhalation (5% CO(2)) increased blood flow by 12 +/- 4% relative to air (P < 0.01, N = 5). This study demonstrates the feasibility of blood-flow MRI of the retina of unanesthetized human. Because blood flow is tightly coupled to metabolic function under normal conditions and it is often perturbed in diseases, this approach could provide unique insights into retinal physiology and serve as an objective imaging biomarker for disease staging and testing of novel therapeutic strategies. This approach could open up new avenue of retinal research. Magn Reson Med 65:1768-1775, 2011. (C)2011 Wiley-Liss, Inc.

AB The aim of this study was to estimate the validity of the Upper Limb Neurodynamic Test 1 (ULNT1) for the diagnosis of Carpal Tunnel Syndrome (CTS) with blind comparison to a reference criterion of a compatible clinical presentation and abnormal nerve conduction. 47 subjects with suspected CTS were enrolled. All patients were tested with nerve conduction studies and ULNT1. Considering results as positive in the presence of reproduction of symptoms on affected upper limb, or side-to-side differences in elbow extension, or symptoms modified by lateral neck side-bending, we estimated sensitivity as 91.67%, specificity as 15%, positive likelihood ratio as 1.0784, negative likelihood ratio as 0.5556, and post-test probability for negative test as 40%. Using a new criterion, i.e. the reproduction of symptoms only in the first three digits of the affected hand, we estimated sensitivity as 54.17%, specificity as 70%, positive and negative likelihood ratios as 1.8056 and 0.6548, respectively, and post-test probability for positive test as 68%. Our investigation suggests that the reproduction of the typical current CTS symptoms in the affected hand during ULNT1 testing, improves estimation of the probability of the presence of this condition, even if this test alone cannot be used to diagnose CTS.

AB Alpha-1-antitrypsin (AAT) is the primary circulating serine protease inhibitor, and is known to exert potent anti-inflammatory effects and to inhibit the progression of several autoimmune diseases. In this study, transgenic mice that over-express surfactant-driven human (h)AAT on the C57BL/6 background were evaluated for resistance to MOG-35-55 peptide-induced experimental autoimmune encephalomyelitis (EAE), compared to WT C57BL/6 control mice. According to the results, sustained levels of circulating hAAT profoundly inhibited induction of clinical signs, inflammatory lesions and demyelination observed in WT mice with EAE, concomitant with enhanced levels of CD4+FoxP3+ Treg cells, reduced secretion of MOG peptide-induced pro-inflammatory cytokines, IL-17, IL-1 beta & IL-6, diminished expression of caspase-1 and enhanced expression of CCR6. These results implicate hAAT as a potent immunoregulatory agent worthy of further investigation as a potential therapy in human autoimmune diseases including multiple sclerosis.

AB Stroke induces a biphasic effect on the peripheral immune response that involves early activation of peripheral leukocytes followed by severe immunosuppression and atrophy of the spleen. Peripheral immune cells, including T lymphocytes, migrate to the brain and exacerbate the developing infarct. Recombinant T-cell receptor (TCR) Ligand (RTL)551 is designed as a partial TCR agonist for myelin oligodendrocyte glycoprotein (MOG)-reactive T cells and has demonstrated the capacity to limit infarct volume and inflammation in brain when administered to mice undergoing middle cerebral artery occlusion (MCAO). The goal of this study was to determine if RTL551 could retain protection when given within the therapeutically relevant 4 h time window currently in clinical practice for stroke patients. RTL551 was administered subcutaneously 4 h after MCAO, with repeated doses every 24 h until the time of euthanasia. Cell numbers were assessed in the brain, blood, spleen and lymph nodes and infarct size was measured after 24 and 96 h reperfusion. RTL551 reduced infarct size in both cortex and striatum at 24 h and in cortex at 96 h after MCAO and inhibited the accumulation of inflammatory cells in brain at both time points. At 24 h post-MCAO, RTL551 reduced the frequency of the activation marker, CD44, on T-cells in blood and in the ischemic hemisphere. Moreover, RTL551 reduced expression of the chemokine receptors, CCR5 in lymph nodes and spleen, and CCR7 in the blood and lymph nodes. These data demonstrate effective treatment of experimental stroke with RTL551 within a therapeutically relevant 4 h time window through immune regulation of myelin-reactive inflammatory T-cells.

AB Noninvasive detection and in vivo imaging of apoptosis plays a critical role in the development of therapeutics in many different fields including cancer. We have developed an apoptosis biosensor by fusing green fluorescent protein (GFP) to the N-terminus of the naturally secreted Gaussia luciferase separated by a caspase-3 cleavage peptide consisting of aspartic acid (D), glutamic acid (E), valine (V), and aspartic acid (D) or DEVD. We showed that this fusion is retained in the cytoplasm of cells in an inactive form. Upon apoptosis, the DEVD peptide is cleaved in response to caspase-3 activation, freeing ssGluc, which can now enter the secretory pathway where it is folded properly and is released from the cells and can be detected in the conditioned medium in culture or in blood of live animals ex vivo over time. Because Gluc is secreted from cells via conventional pathway through the endoplasmic reticulum (ER), Golgi and vesicles, we showed that the presence of Gluc in these compartments in response to apoptosis can be visualized in vivo using bioluminescence imaging. This reporter provides a valuable tool for imaging and real-time monitoring of apoptosis and is compatible with high-throughput functional screening application in cultured cells and animal models.

AB We have systematically compared copy number variant (CNV) detection on eleven microarrays to evaluate data quality and CNV calling, reproducibility, concordance across array platforms and laboratory sites, breakpoint accuracy and analysis tool variability. Different analytic tools applied to the same raw data typically yield CNV calls with <50% concordance. Moreover, reproducibility in replicate experiments is <70% for most platforms. Nevertheless, these findings should not preclude detection of large CNVs for clinical diagnostic purposes because large CNVs with poor reproducibility are found primarily in complex genomic regions and would typically be removed by standard clinical data curation. The striking differences between CNV calls from different platforms and analytic tools highlight the importance of careful assessment of experimental design in discovery and association studies and of strict data curation and filtering in diagnostics. The CNV resource presented here allows independent data evaluation and provides a means to benchmark new algorithms.

AB Reversible histone methylation and demethylation are highly regulated processes that are crucial for chromatin reorganization and regulation of gene transcription in response to extracellular conditions. However, the mechanisms that regulate histone-modifying enzymes are largely unknown. Here, we characterized a protein kinase A (PKA)-dependent histone lysine demethylase complex, PHF2-ARID5B. PHF2, a jmjC demethylase, is enzymatically inactive by itself, but becomes an active H3K9Me2 demethylase through PKA-mediated phosphorylation. We found that phosphorylated PHF2 then associates with ARID5B, a DNA-binding protein, and induce demethylation of methylated ARID5B. This modification leads to targeting of the PHF2 ARID5B complex to its target promoters, where it removes the repressive H3K9Me2 mark. These findings suggest that the PHF2 ARID5B complex is a signal-sensing modulator of histone methylation and gene transcription, in which phosphorylation of PHF2 enables subsequent formation of a competent and specific histone demethylase complex.

AB Brain metastases are a serious obstacle in the treatment of patients with solid tumors and contribute to the morbidity and mortality of these cancers. It is speculated that the frequency of brain metastasis is increasing for several reasons, including improved systemic therapy and survival, and detection of metastases in asymptomatic patients. The lack of preclinical models that recapitulate the clinical setting and the exclusion of patients with brain metastases from most clinical trials have slowed progress. Molecular factors contributing to brain metastases are being elucidated, such as genes involved in cell adhesion, extravasation, metabolism, and cellular signaling. Furthermore, the role of the unique brain microenvironment is beginning to be explored. Although the presence and function of the blood-brain barrier in metastatic tumors is still poorly understood, it is likely that some tumor cells are protected from therapeutics by the blood-tumor barrier, creating a sanctuary site. This Review discusses what is known about the biology of brain metastases, what preclinical models are available to study the disease, and which novel therapeutic strategies are being studied in patients.

AB Depression is highly common throughout the life course and dementia is common in late life. Depression has been linked with dementia, and growing evidence implies that the timing of depression may be important in defining the nature of this association. In particular, earlier-life depression (or depressive symptoms) has consistently been associated with a more than twofold increase in dementia risk. By contrast, studies of late-life depression and dementia risk have been conflicting; most support an association, yet the nature of this association (for example, if depression is a prodrome or consequence of, or risk factor for dementia) remains unclear. The likely biological mechanisms linking depression to dementia include vascular disease, alterations in glucocorticoid steroid levels and hippocampal atrophy, increased deposition of amyloid-beta plaques, inflammatory changes, and deficits of nerve growth factors. Treatment strategies for depression could interfere with these pathways and alter the risk of dementia. Given the projected increase in dementia incidence in the coming decades, understanding whether treatment for depression alone, or combined with other regimens, improves cognition is of critical importance. In this Review, we summarize and analyze current evidence linking late-life and earlier-life depression and dementia, and discuss the primary underlying mechanisms and implications for treatment.

AB Background: Because common viruses are encountered during childhood, pediatric multiple sclerosis (MS) offers a unique opportunity to investigate the influence of these viruses on disease susceptibility and the interactions between seroprevalence and select HLA genotypes. We studied seroprevalence for Epstein-Barr virus (EBV), cytomegalovirus (CMV), and herpes simplex virus (HSV) type 1 and HLA-DRB1*1501/1503 status as predictors of pediatric MS.
Methods: This was a retrospective analysis of prospectively collected demographic, clinical, and biologic data in subjects up to 18 years of age with early MS, control subjects seen at the same regional referral pediatric MS clinics, and additional healthy pediatric control subjects.
Results: Patients with early pediatric MS (n = 189) and pediatric control subjects (n = 66) were tested. Epstein-Barr nuclear antigen-1 seropositivity was associated with an increased odds of MS (odds ratio [OR] 3.78, 95% confidence interval [CI] 1.52-9.38, p = 0.004) in analyses adjusted for age, sex, race, ethnicity, and HLA-DRB1*1501/1503 status. In multivariate analyses including EBV status, a remote infection with CMV (OR 0.27,95% CI 0.11-0.67, p = 0.004) was associated with a lower risk of developing MS. Although a remote infection with HSV-1 was not associated with an increased odds of MS, a strong interaction was found between HSV-1 status and HLA-DRB1 in predicting MS (p < 0.001). HSV-1 was associated with an increased risk of MS in those without a DRB1*15 allele (OR 4.11, 95% CI 1.17-14.37, p = 0.03), whereas the effect was reversed in those who were DRB1*15-positive (OR 0.07, 95% CI 0.02-0.32, p = 0.001).
Conclusions: These findings suggest that some infections with common viruses may in fact lower MS susceptibility. If this is confirmed, the pathways for risk modification remain to be elucidated. Neurology (R) 2011;76:1989-1995

DT Article

AB Object. Previous methods to determine stroke prevalence, such as nationwide surveys, are labor-intensive endeavors. Recent advances in search engine query analytics have led to a new metric for disease surveillance to evaluate symptomatic phenomenon, such as influenza. The authors hypothesized that the use of search engine query data can determine the prevalence of stroke.
Methods. The Google Insights for Search database was accessed to analyze anonymized search engine query data. The authors' search strategy utilized common search queries used when attempting either to identify the signs and symptoms of a stroke or to perform stroke education. The search logic was as follows: (stroke signs + stroke symptoms + mini stroke - heat) from January 1, 2005, to December 31, 2010.
The relative number of searches performed (the interest level) for this search logic was established for all 50 states and the District of Columbia. A Pearson product-moment correlation coefficient was calculated from the state-specific stroke prevalence data previously reported.
Results. Web search engine interest level was available for all 50 states and the District of Columbia over the time period for January 1, 2005-December 31, 2010. The interest level was highest in Alabama and Tennessee (100 and 96, respectively) and lowest in California and Virginia (58 and 53, respectively). The Pearson correlation coefficient (r) was calculated to be 0.47 (p = 0.0005, 2-tailed).
Conclusions. Search engine query data analysis allows for the determination of relative stroke prevalence. Further investigation will reveal the reliability of this metric to determine temporal pattern analysis and prevalence in this and other symptomatic diseases. (DOI: 10.3171/2011.2.FOCUS1124)

AB Microalbuminuria is a common condition associated with increased incidence of cardiovascular events and mortality. Abdominal obesity is associated with microalbuminuria, but studies linking visceral adipose tissue (VAT) and microalbuminuria are limited. Our objective was to determine the associations of albuminuria with VAT and subcutaneous adipose tissue (SAT). We performed a cross-sectional study in the Framingham Multi-Detector Computed Tomography (MDCT) cohort (n = 3,099, 48.2% women, mean age 53 years). VAT and SAT volumes were measured using computed tomography. Urinary albumin-to-creatinine ratio (UACR) was calculated from spot urine samples. Microalbuminuria was defined as a UACR >25 mg/g in women or >17 mg/g in men. Overall, 7.9% (n = 244) of the sample had microalbuminuria. Among men, VAT (odds ratio (OR) 1.48 per s.d., P < 0.0001) and SAT (OR 1.37 per s.d., P = 0.0002) were associated with microalbuminuria in minimally adjusted models, which remained significant after multivariable adjustment (VAT OR 1.34 per s.d., P = 0.001; SAT OR 1.28 per s.d., P = 0.005). Additionally, when considered jointly, VAT (P = 0.002) but not SAT (P = 0.2) was associated with microalbuminuria. In women, VAT was associated with microalbuminuria after minimal adjustment (OR 1.28, P = 0.01), but not after multivariable adjustment (OR 1.03, P = 0.8). In multivariable models in women, SAT was associated with a decreased odds of having microalbuminuria (OR 0.75 per s.d., P = 0.03). In conclusion, VAT is associated with microalbuminuria in men but not women. Albuminuria may be a manifestation of visceral adiposity.

AB We investigated the impact of obesity on the abnormalities of systolic and diastolic regional left ventricular (LV) function in patients with or without hypertension or hypertrophy, and without heart failure. We studied 120 individuals divided into 6 groups of 20 patients (42 +/- 6 years, 60 females) using standard and pulsed-wave tissue Doppler imaging (TDI) echocardiography, and heterogeneity index (HI): nonobese (I: no hypertension, no hypertrophy, control group; II: hypertension, no hypertrophy; III: hypertension and hypertrophy) and obese (IV: no hypertension, no hypertrophy; V: hypertension, no hypertrophy; VI: hypertension and hypertrophy). The criterion for obesity was BMI >= 30 kg/m(2), for hypertension was blood pressure >= 140/90 mm Hg, for hypertrophy in nonobese was LV mass/body surface area (BSA) >134 g/m(2) (men) and >110 mg/m(2) (women), and in obese was LV mass/height((2.7)) >50 (men) and >40 (women). Obese groups had normal LV ejection fraction compared with nonobese groups, but decreased longitudinal and radial systolic myocardial peak velocities (S'), and early diastolic myocardial peak velocity (E'). Also, a great variability of E' and late diastolic myocardial peak velocity (A') from the longitudinal basal region was observed in obese groups (E' basal nonobese: 11 +/- 7 vs. obese 19 +/- 11, P < 0.001, A' basal nonobese: 7 +/- 4 vs. obese 11 +/- 7, P < 0.001). Our findings were more evident when comparing groups IV with V and VI, with the latter having concentric hypertrophy and obvious segmental systolic and diastolic dysfunctions. Subclinical myocardial alterations and increased variability of the velocities were observed in obese groups, especially with hypertension and hypertrophy, reflecting impaired regional LV relaxation, segmental atrial, and systolic dysfunctions.

AB There is a strong rationale to therapeutically target the phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/AKT/mTOR) pathway in breast cancer since it is highly deregulated in this disease and it also mediates resistance to anti-HER2 therapies. However, initial studies with rapalogs, allosteric inhibitors of mTORC1, have resulted in limited clinical efficacy probably due to the release of a negative regulatory feedback loop that triggers AKT and ERK signaling. Since activation of AKT occurs via PI3K, we decided to explore whether PI3K inhibitors prevent the activation of these compensatory pathways. Using HER2-overexpressing breast cancer cells as a model, we observed that PI3K inhibitors abolished AKT activation. However, PI3K inhibition resulted in a compensatory activation of the ERK signaling pathway. This enhanced ERK signaling occurred as a result of activation of HER family receptors as evidenced by induction of HER receptors dimerization and phosphorylation, increased expression of HER3 and binding of adaptor molecules to HER2 and HER3. The activation of ERK was prevented with either MEK inhibitors or anti-HER2 monoclonal antibodies and tyrosine kinase inhibitors. Combined administration of PI3K inhibitors with either HER2 or MEK inhibitors resulted in decreased proliferation, enhanced cell death and superior anti-tumor activity compared with single agent PI3K inhibitors. Our findings indicate that PI3K inhibition in HER2-overexpressing breast cancer activates a new compensatory pathway that results in ERK dependency. Combined anti-MEK or anti-HER2 therapy with PI3K inhibitors may be required in order to achieve optimal efficacy in HER2-overexpressing breast cancer. This approach warrants clinical evaluation.

AB OBJECTIVE: To describe demographic and clinical characteristics and outcomes of patients who received hospital-based pediatric palliative care (PPC) consultations.
DESIGN, SETTING, AND PATIENTS: Prospective observational cohort study of all patients served by 6 hospital-based PPC teams in the United States and Canada from January to March 2008.
RESULTS: There were 515 new (35.7%) or established (64.3%) patients who received care from the 6 programs during the 3-month enrollment interval. Of these, 54.0% were male, and 69.5% were identified as white and 8.1% as Hispanic. Patient age ranged from less than one month (4.7%) to 19 years or older (15.5%). Of the patients, 60.4% lived with both parents, and 72.6% had siblings. The predominant primary clinical conditions were genetic/congenital (40.8%), neuromuscular (39.2%), cancer (19.8%), respiratory (12.8%), and gastrointestinal (10.7%). Most patients had chronic use of some form of medical technology, with gastrostomy tubes (48.5%) being the most common. At the time of consultation, 47.2% of the patients had cognitive impairment; 30.9% of the cohort experienced pain. Patients were receiving many medications (mean: 9.1). During the 12-month follow-up, 30.3% of the cohort died; the median time from consult to death was 107 days. Patients who died within 30 days of cohort entry were more likely to be infants and have cancer or cardiovascular conditions.
CONCLUSIONS: PPC teams currently serve a diverse cohort of children and young adults with life-threatening conditions.In contrast to the reported experience of adult-oriented palliative care teams, most PPC patients are alive for more than a year after initiating PPC. Pediatrics 2011;127:1094-1101

These decisions provide an interesting case study of the role of scientific evidence in the assessment of food additives and risk to children's health and formulation of food policy. Although there continues to be uncertainty concerning the link between AFCs and attention-deficit/hyperactivity disorder (ADHD), policy decisions have been made that have far-reaching implications. In addition, publicity surrounding the policy changes may shape public perceptions concerning effective management of ADHD. We believe that the balance of existing evidence neither refutes nor supports the link between AFCs and ADHD, which highlights the need for carefully designed studies to further investigate the link between AFCs and ADHD. In this article we describe a model for such studies. In developing our model, we drew from current investigative standards in ADHD research, such as those used in the landmark Multimodal Treatment Study of Children With ADHD. These standards encompass methodologic considerations including sample selection, outcome assessment, and data analyses. It is our hope that this model research methodology may prove valuable in addressing design considerations in future studies of AFCs and ADHD with the goal of producing reliable data that will enable policy-makers to better formulate effective, evidence-based food-policy decisions.

AB Genetic studies indicate that alcohol consumption associates with expression of the P2rx4 gene, a gene that codes for the P2X(4) receptor. This receptor is a subtype in the purinergic system of ligand-gated ion channels that when activated exerts excitatory effects in CNS. P2X(4) function is inhibited by alcohol and P2X(4) receptors are modulated positively by the antiparasitic agent, ivermectin. Two experiments were performed to test the ability of ivermectin to alter the behavioral effects of alcohol in rats. After alcohol exposure was achieved via the "drinking in the dark" procedure, separate groups of Sprague-Dawley rats were trained to lever press for either alcohol (10% ethanol/2% sucrose) or sucrose (3%) solutions in operant chambers. Rats were tested for maintenance of operant self-administration under a progressive ratio condition (Experiment 1) and for reinstatement of extinguished responding induced by solution presentation (Experiment 2) after ivermectin (0; 1-10 mg/kg; IP) administration. Ivermectin decreased the amount of work that the animal performed to obtain reinforcers in the maintenance study, particularly in the group reinforced with alcohol, and tended to decrease reinstated lever press responding. Conditioned approach behavior (head entries) was significantly reduced by ivermectin in both experiments. Reduction in motor activity was seen during the longer maintenance sessions but not in the shorter reinstatement sessions. Results suggest some support for ivermectin-like drugs as potential treatment agents for alcohol dependence. Caution is warranted due to modest specificity on behavior reinforced by alcohol, some reduction in general activity levels, and the lack of dose-response effects. (C) 2011 Elsevier Inc.

AB Objective: The purpose of this study was to Investigate the effect of 810-nm low level laser therapy (LLLT) on dendritic cells (DC) in vitro. Background data: LLLT can enhance wound healing and increase cell proliferation and survival, and is used to treat inflammatory conditions. However there are reports that LLLT can stimulate leukocytes and could therefore be pro-inflammatory. Recently, DC have been found to play an important role in inflammation and immune response. Methods: Murine bone-marrow-derived DC were isolated, stimulated with lipopolysaccharide (LPS) or CpG oligodeoxynucleotide and treated with 810-nm laser, using fluences of 0.3, 3, and 30 J/cm(2) delivered at irradiances of 1, 10, and 100mW/cm(2) respectively. Confocal microscopy, flow cytometry for DC markers, viability using propidium iodide, enzyme-linked immunosorbent assays (ELISA) for secreted interleukin-12 (IL-12), and bioluminescence measurements in cells transduced with a reporter for toll-like receptor (TLR)-9/nuclear factor kappa B (NF-kappa B) activation, were performed. Results: LLLT changed the morphology of LPS-stimulated DC, increased their viability, and altered the balance of DC activation markers (major histocompatibility complex [MHC] class 2 up and CD86 down). LLLT reduced IL-12 secretion from DC stimulated by either LPS or CpG. LLLT reduced NF-kappa B activation in reporter cells stimulated with CpG. There was no obvious light dose response observed. Conclusions: Taken together, these data suggest that 810-nm LLLT has an anti-inflammatory effect on activated DC, possibly mediated by cyclic adenosine monophosphate (cAMP) and reduced NF-kappa B signaling.

AB We performed targeted mutagenesis of a transgene and nine endogenous soybean (Glycine max) genes using zinc-finger nucleases (ZFNs). A suite of ZFNs were engineered by the recently described context-dependent assembly platform-a rapid, open-source method for generating zinc-finger arrays. Specific ZFNs targeting DICER-LIKE (DCL) genes and other genes involved in RNA silencing were cloned into a vector under an estrogen-inducible promoter. A hairy-root transformation system was employed to investigate the efficiency of ZFN mutagenesis at each target locus. Transgenic roots exhibited somatic mutations localized at the ZFN target sites for seven out of nine targeted genes. We next introduced a ZFN into soybean via whole-plant transformation and generated independent mutations in the paralogous genes DCL4a and DCL4b. The dcl4b mutation showed efficient heritable transmission of the ZFN-induced mutation in the subsequent generation. These findings indicate that ZFN-based mutagenesis provides an efficient method for making mutations in duplicate genes that are otherwise difficult to study due to redundancy. We also developed a publicly accessible Web-based tool to identify sites suitable for engineering context-dependent assembly ZFNs in the soybean genome.

AB Background: Autologous fat grafting is currently undergoing a renaissance. However, fat grafts are limited by unpredictable survival. Poloxamers can act as tissue surfactants. These nonionic surfactants have been shown to stabilize the membranes of damaged cells and to protect against injury and apoptosis in numerous models. This study was designed to investigate the ability of poloxamers to protect harvested adipocytes and to increase fat graft survival.
Methods: Lipoaspirate was obtained from surgical patients. Samples were washed in normal saline, centrifuged at 200 g, treated with various poloxamers or poloxamer components for 30 minutes, centrifuged at 200 g, and implanted into the flanks of nude mice in 1.0-cc, 1.0-g lobules. The grafts were explanted serially for 10 days and at 6 weeks. Endpoints were weight, apoptosis, cell viability, DNA content, and histology.
Results: Grafts treated with poloxamers P188, F108, and F127 demonstrated increased graft survival by weight. Fat grafts treated with poloxamers L64 and P188 demonstrated improvement in cell viability, and those treated with poloxamers L64, P188, and F38 demonstrated improved histology. P188-treated grafts demonstrated a 50 percent reduction in apoptosis compared with saline-treated controls (p < 0.05) and an overall 72 percent survival by weight at 6 weeks. P188 demonstrated statistically significant improvement by weight, DNA content, histology, and cell viability (89 percent versus 33 percent).
Conclusions: The authors demonstrate that poloxamers, with membrane-sealing capability, can increase graft survival. Among these poloxamers, P188 demonstrated statistically significant improvement in apoptosis, graft survival by weight, cell viability, DNA content, and histology. (Plast. Reconstr.

AB Background: Development of a tissue engineered bone graft requires efficient bioactivity screening of biomaterials in clinically relevant three-dimensional systems. The authors analyzed the relative osteogenic potential of two three-dimensional biomaterials-type I collagen and poly(L-lactide-co-glycolide) (PLGA)-to support in vitro mineralization of human mesenchymal stem cells.
Methods: Human mesenchymal stem cells were seeded onto three-dimensional PLGA or type I collagen scaffolds; incubated in osteogenic media; and harvested at 1, 4, and 7 days. Messenger RNA expression was analyzed using quantitative real-time reverse-transcriptase polymerase chain reaction for osteogenic (i.e., alkaline phosphatase, osteocalcin, bone sialoprotein, Runx2/core binding factor alpha-1) and angiogenic (i.e., vascular endothelial growth factor and interleukin-8) markers. Alkaline phosphatase enzyme activity was measured at 4 and 7 days. Mineralization was detected by alizarin red staining and micro-computed tomographic imaging at 8 and 12 weeks. Mineral composition was analyzed by solid-phase nuclear magnetic resonance spectroscopy.
Results: Early osteogenic and angiogenic markers, and alkaline phosphatase enzyme activity, were up-regulated on PLGA versus collagen scaffolds. However, long-term mineralization endpoints favored type I collagen. By 8 weeks, human mesenchymal stem cells on collagen exhibited significantly higher mineral density by micro-computed tomographic and alizarin red staining than PLGA scaffolds. Both biomaterials deposited calcium hydroxyapatite as determined by nuclear magnetic resonance spectroscopy.
Conclusions: The authors' findings suggest that despite early PLGA induction of osteogenic gene expression, long-term mineralization occurs earlier and to a greater extent on type I collagen, highlighting collagen as a potential bone tissue engineering scaffold in the human mesenchymal stem cell niche. When screening the relative osteoinductive profiles of three-dimensional bone tissue engineering scaffolds in vitro, the authors recommend including long-term endpoints of osteogenesis. (Plast.

AB Objective: To study health care utilization patterns in patients with gout.
Methods: In a gout population from primary care and rheumatology clinics in 3 U.S. metropolitan cities, we collected data on gout-related utilization (primary care, rheumatology, urgent care, emergency room, and other) in the past year. We evaluated the association of comorbidities, age, gender, gout characteristics (time since last gout attack and tophi), and gout severity ratings (mean of serum uric acid, patient-rated, and physician-rated gout severity) and with emergency/urgent care and primary care utilization using regression and correlation analyses.
Results: Of the 296 patients who reported visiting at least 1 type of health practitioner for gout in the past year, the percentage of patients utilizing the service at least once and annual utilization rates among utilizers were as follows: primary care physician, 60%, 3.0 +/- 3.4; nurse practitioner/physician assistant, 26%, 2.7 +/- 2.5; rheumatologist, 51%, 3.7 +/- 5.7; urgent care, 23%, 2.1 +/- 2.2; emergency room, 20%, 2.0 +/- 1.7; and hospitalization, 7%, 2.1 +/- 1.4. Higher overall gout severity was associated with greater use of each resource type and with overall gout-related utilization. Nonemergency/nonurgent care utilization (primary care physician, nurse practitioner, physician's assistant, and rheumatologist for gout) was the strongest predictor of gout-related emergency/urgent care utilization. Patients with more comorbidities had greater gout-related primary care utilization.
Conclusions: Overall gout severity was associated with all types of gout-related utilization. This may help to screen high utilizers for targeted behavioral and therapeutic interventions. Having a higher number of comorbid conditions was a risk factor for higher gout-related primary care utilization. Published by Elsevier Inc. Semin Arthritis Rheum 40:501-511

AB Study Objectives: To compare the breathing instability and upper airway collapsibility between patients with pure OSA (i.e. 100% of apneas are obstructive) and patients with predominant OSA (i.e., coexisting obstructive and central apneas).
Design: A cross-sectional study with data scored by a fellow being blinded to the subjects' classification. The results were compared between the 2 groups with unpaired student t-test.
Setting and interventions: Standard polysomnography technique was used to document sleep-wake state. Ventilator in pressure support mode was used to introduce hypocapnic apnea during CO(2) reserve measurement. CPAP with both positive and negative pressures was used to produce obstructive apnea during upper airway collapsibility measurement.
Participants: 21 patients with OSA: 12 with coexisting central/mixed apneas and hypopneas (28% +/- 6% of total), and 9 had pure OSA.
Measurements: The upper airway collapsibility was measured by assessing the critical closing pressure (Pcrit). Breathing stability was assessed by measuring CO(2) reserve (i.e.,Delta PCO(2) [eupnea-apnea threshold]) during NREM sleep.
Results: There was no difference in Pcrit between the 2 groups (pure OSA vs. predominant OSA: 2.0 +/- 0.4 vs. 2.7 +/- 0.4 cm H(2)O, P = 0.27); but the CO(2) reserve was significantly smaller in predominant OSA group (1.6 +/- 0.7 mm Hg) than the pure OSA group (3.8 +/- 0.6 mm Hg) (P = 0.02).
Conclusions: The present data indicate that breathing stability rather than upper airway collapsibility distinguishes OSA patients with a combination of obstructive and central events from those with pure OSA.

TI A Novel Approach to Increase Residents' Involvement in Reporting Adverse
Events
SO ACADEMIC MEDICINE
LA English
DT Article
ID IMPROVE PATIENT SAFETY; QUALITY IMPROVEMENT; MEDICAL ERRORS; TEACHING
HOSPITALS; PHYSICIANS; EDUCATION
AB Purpose
In the wake of the Patient Safety and Quality Improvement Act of 2005, national attention has increasingly focused on adverse-event reporting as a means of identifying systems changes to improve patient safety. However, physicians and residents have demonstrated meager involvement in this effort.
Method
In 2008-2009, the authors measured participation in adverse-event reporting by 680 residents at Oregon Health & Science University before and after implementing a quality improvement initiative, which consisted of a financial incentive and multifaceted educational campaign. The primary measure of success was an increase in the average monthly adverse-event reports submitted by residents to greater than 5% of the institution's overall report submissions.
Results
The average number of adverse events reported by residents increased from 1.6% to 9.0% of the institution's overall event reports, representing a 5.6-fold increase during the initiative (P < .001). The relative percentage of resident-submitted reports defined as "near-misses" increased from 6% to 27% during the initiative (P < .001).
Conclusions
The novel approach of integrating a retirement benefit and educational campaign to increase residents' involvement in adverse-event reporting was successful. In addition to increasing residents' contributions to adverse-event reporting to levels higher than any documented in the current literature, there was also a remarkable increase in the relative frequency of near-miss reporting by residents.

AB Merkulova M, Hurtado-Lorenzo A, Hosokawa H, Zhuang Z, Brown D, Ausiello DA, Marshansky V. Aldolase directly interacts with ARNO and modulates cell morphology and acidic vesicle distribution. Am J Physiol Cell Physiol 300: C1442-C1455, 2011. First published February 9, 2011; doi: 10.1152/ajpcell.00076.2010.-Previously, we demonstrated that the vacuolar-type H(+)-ATPase (V-ATPase) a2-subunit functions as an endosomal pH sensor that interacts with the ADP-ribosylation factor (Arf) guanine nucleotide exchange factor, ARNO. In the present study, we showed that ARNO directly interacts not only with the a2-subunit but with all a-isoforms (a1-a4) of the V-ATPase, indicating a widespread regulatory interaction between V-ATPase and Arf GTPases. We then extended our search for other ARNO effectors that may modulate V-ATPase-dependent vesicular trafficking events and actin cytoskeleton remodeling. Pull-down experiments using cytosol of mouse proximal tubule cells (MTCs) showed that ARNO interacts with aldolase, but not with other enzymes of the glycolytic pathway. Direct interaction of aldolase with the pleckstrin homology domain of ARNO was revealed by pull-down assays using recombinant proteins, and surface plasmon resonance revealed their high avidity interaction with a dissociation constant: K(D) = 2.84 x 10(-10) M. MTC cell fractionation revealed that aldolase is also associated with membranes of early endosomes. Functionally, aldolase knockdown in HeLa cells produced striking morphological changes accompanied by long filamentous cell protrusions and acidic vesicle redistribution. However, the 50% knockdown we achieved did not modulate the acidification capacity of endosomal/lysosomal compartments. Finally, a combination of small interfering RNA knockdown and overexpression revealed that the expression of aldolase is inversely correlated with gelsolin levels in HeLa cells. In summary, we have shown that aldolase forms a complex with ARNO/Arf6 and the V-ATPase and that it may contribute to remodeling of the actin cytoskeleton and/or the trafficking and redistribution of V-ATPase-dependent acidic compartments via a combination of protein-protein interaction and gene expression mechanisms.

AB Endothelial progenitor cells (EPCs) play an essential role in angiogenesis but are functionally impaired in diabetes. We recently reported that decreased expression of manganese superoxide dismutase (MnSOD) critically contributes to diabetic EPC dysfunction. AMP-activated protein kinase (AMPK) activation has been shown to induce MnSOD and suppress hyperglycemia-induced mitochondrial ROS production in endothelial cells. However, whether AMPK protects EPCs from oxidative stress in diabetes is unknown. We tested the hypothesis that AMPK activation rescues impaired EPC functions through MnSOD induction in type 1 diabetes. Bone marrow-derived EPCs from adult male streptozotocin-induced diabetic mice and normal controls were used. AMPK activity was decreased in diabetic EPCs, indicated by reduced AMPK and acetyl-CoA carboxylase phosphorylation. AMPK activation by treating diabetic EPCs with its selective agonist AICAR rescued their in vitro functions, including Matrigel tube formation, adhesion, and migration. Furthermore, AICAR restored the decreased MnSOD protein and enzymatic activity and suppressed the mitochondrial superoxide level in diabetic EPCs, indicated by MitoSOX flow cytometry. These beneficial effects of AICAR on MnSOD and EPC functions were significantly attenuated by silencing MnSOD or AMPK antagonist compound C pretreatment. Finally, the expression of protein phosphatase 2A, a key enzyme for AMPK dephosphorylation and inactivation, was increased in diabetic EPCs, and its inhibition by siRNA or okadaic acid reversed the deficient AMPK activation and MnSOD level in diabetic EPCs. These findings demonstrate for the first time that AMPK activation rescues impaired EPC functions and suppresses mitochondrial superoxide by inducing MnSOD in type 1 diabetes.

AB Purpose: The purpose of this study was to objectively evaluate whether double-bundle anterior cruciate ligament (ACL) reconstruction can better restore the normal translational and rotational laxities than the conventional single-bundle ACL reconstruction among the reported biomechanical studies. Methods: A systematic literature search was conducted to identify in vitro and in vivo (intraoperative) biomechanical studies that compared the laxities (anterior or anteroposterior or rotational) between single-and double-bundle ACL reconstructions. Because of large variability among the loading conditions and testing methods used to determine the rotational laxities among the studies, a meta-analysis of rotational laxities was not feasible. Results: Seven in vitro and three in vivo studies were included in this analysis based on the predefined inclusion criteria. The overall mean differences calculated by the random effects model in anteroposterior laxity between the single-bundle and double-bundle ACL reconstruction techniques at 0 degrees, 30 degrees, 60 degrees, and 90 degrees of flexion were 0.99 mm, 0.38 mm, 0.34 mm, and 0.07 mm, respectively. No statistically significant difference was noted between the 2 treatments at all flexion angles. Among the 9 studies that compared the rotational laxity of single-bundle and double-bundle ACL reconstructions, 4 reported that double-bundle reconstruction can provide better rotational control than single-bundle reconstruction. The other 5 studies could not identify any significant difference between the 2 reconstructions in terms of rotational laxity. Conclusions: Both single-and double-bundle treatment options for ACL injury result in similar anteroposterior knee joint laxity at time 0. No conclusive evidence on the superiority of 1 reconstruction technique over the other in terms of rotation laxity can be obtained because of several variations in the experimental protocol and the kinematics used to measure the rotational laxity among the studies. Level of Evidence: Level III, meta-analysis.

AB Here we describe a novel functional screening assay based on bioluminescence monitoring of the naturally secreted Gaussia luciferase (Gluc) in the conditioned medium of cultured cells. Using this assay, we identified small-molecule drugs that sensitized brain tumor cells to the tumor necrosis factor-related apoptosis-inducing ligand-induced cell death. Human glioblastoma multiforme cells were engineered by gene transfer to express Gluc as a reporter for cell viability, which can be monitored over time by bioluminescence measurements using a plate luminometer. We have optimized the Gluc assay for screening and validated it using the National Institute of Neurological Disorders and Stroke (NINDS) custom collection II library consisting of 1,040 drugs and bioactive compounds, most of which are Food and Drug Administration-approved and are able to cross the blood-brain barrier. We found that the cardiac glycosides family sensitized glioblastoma multiforme cells to the tumor necrosis factor-related apoptosis-inducing ligand-induced apoptosis. In conclusion, the Gluc secretion assay is a robust tool for functional drug screening and can be applied to many different fields including cancer.

AB P>This open-label, dose escalation, multicentre phase 1/2 trial was undertaken to determine the safety and tolerability of the heat shock protein 90 (HSP90) inhibitor tanespimycin (100-340 mg/m2) + bortezomib (0 center dot 7-1 center dot 3 mg/m2) given on days 1, 4, 8 and 11 in each 21-d cycle. Phase 2 expansion occurred at the highest tested dose of tanespimycin at 340 mg/m2 and bortezomib at 1 center dot 3 mg/m2. Seventy-two patients (median age, 60 years) with relapsed or relapsed and refractory multiple myeloma (MM) were enrolled; 63 patients (89%) completed the study. Tanespimycin in combination with bortezomib was well tolerated; few patients experienced significant neutropenia, constipation and anorexia (< 10%), and no patients developed severe peripheral neuropathy. Among 67 efficacy-evaluable patients, there were 2 (3%) complete responses and 8 (12%) partial responses, for an objective response rate (ORR) of 27%, including 8 (12%) minimal responses. Response rates were highest among bortezomib-naive patients and proved durable in all patient subgroups, including those with bortezomib-refractory disease. Pharmacodynamic analyses indicated that tanespimycin plus bortezomib effectively inhibited the proteasome, as evidenced by decreased 20S proteasome activity, and inhibited HSP90, as reflected by increased HSP70 expression. The results of this study support additional studies of this combination approach in MM.

SO CLINICAL CHEMISTRY
LA English
DT Editorial Material
ID US
AB BACKGROUND: Multiple laboratory tests are used in the diagnosis and management of patients with diabetes mellitus. The quality of the scientific evidence supporting the use of these assays varies substantially.
APPROACH: An expert committee compiled evidence-based recommendations for the use of laboratory analysis in patients with diabetes. A new system was developed to grade the overall quality of the evidence and the strength of the recommendations. A draft of the guidelines was posted on the Internet, and the document was modified in response to comments. The guidelines were reviewed by the joint Evidence-Based Laboratory Medicine Committee of the AACC and the National Academy of Clinical Biochemistry and were accepted after revisions by the Professional Practice Committee and subsequent approval by the Executive Committee of the American Diabetes Association.
CONTENT: In addition to the long-standing criteria based on measurement of venous plasma glucose, diabetes can be diagnosed by demonstrating increased hemoglobin A(1c) (Hb A(1c)) concentrations in the blood. Monitoring of glycemic control is performed by the patients measuring their own plasma or blood glucose with meters and by laboratory analysis of Hb A(1c). The potential roles of noninvasive glucose monitoring, genetic testing, and measurement of autoantibodies, urine albumin, insulin, proinsulin, C-peptide, and other analytes are addressed.
SUMMARY: The guidelines provide specific recommendations based on published data or derived from expert consensus. Several analytes are found to have minimal clinical value at the present time, and measurement of them is not recommended.

TI Using A Multi-Level B-Spline Model to Analyze and Compare Patient
Glucose Profiles Based on Continuous Monitoring Data
SO DIABETES TECHNOLOGY & THERAPEUTICS
LA English
DT Article
ID REAL-TIME; PENALTIES
AB Objective: We show how continuous glucose monitoring (CGM) data can be analyzed using a three-level B-spline model, facilitating the estimation of inter-patient variability, within-patient inter-day variability, and measurement error. We propose methods for statistical comparison of glucose profiles among patient groups.
Methods: We applied a three-level random effects model using quadratic B-spline functions to analyze inter-patient and within-patient inter-day variations of the glucose trend. The estimated SD values of the glucose curves are time-dependent and were averaged over a 24-h period. We analyzed CGM data from 322 patients with type 1 diabetes, 223 patients with type 2 diabetes, and 86 subjects without diabetes using interstitial glucose levels measured every 5 min, for approximately 8 days per patient. We compared group-wide glucose profiles from the insulin pump-treated (n = 124) and multiple daily injection (MDI)-treated (n = 144) patients with type 1 diabetes.
Results: The average inter-patient SD values were 49 mg/dL, 43 mg/dL, and 15 mg/dL for type 1 diabetes patients, type 2 diabetes patients, and subjects without diabetes, respectively. The average within-patient, inter-day SD values were 67 mg/dL, 41 mg/dL, and 18 mg/dL, respectively. The residual SD values were 19 mg/dL, 14 mg/dL, and 8 mg/dL, respectively. We identified a statistically significant difference in glucose profiles during the morning between insulin pump-treated and MDI-treated type 1 diabetes patients.
Conclusions: B-spline models facilitate the analysis of CGM data and show that type 1 diabetes is associated with higher inter-day glucose variation than type 2 diabetes or being without diabetes. Pump therapy and MDI have different effects on glucose control during specific time periods.

AB Although bacterial-fungal interactions shape microbial virulence during polymicrobial infections, only a limited number of studies have evaluated this interaction on a genetic level. We report here that one interaction is mediated by sopB, an effector of a type III secretion system (TTSS) of Salmonella enterica serovar Typhimurium. In these studies, we screened 10 TTSS effector-related mutants and determined their role in the killing of C. albicans filaments in vitro during coinfection in planktonic environments. We found that deleting the sopB gene (which encodes inositol phosphatase) was associated with a significant decrease in C. albicans killing at 25 degrees C after 5 days, similar to that caused by the deletion of sipB (which encodes TTSS translocation machinery components). The sopB deletion dramatically influenced the killing of C. albicans filaments. It was associated with repressed filamentation in the Caenorhabditis elegans model of C. albicans-S. Typhimurium coinfection, as well as with biofilm formation by C. albicans. We confirmed that SopB translocated to fungal filaments through SipB during coinfection. Using quantitative real-time PCR assays, we found that the Candida supernatant upregulated the S. Typhimurium genes associated with C. albicans killing (sopB and sipB). Interestingly, the sopB effector negatively regulated the transcription of CDC42, which is involved in fungal viability. Taken together, these results indicate that specific TTSS effectors, including SopB, play a critical role in bacterial-fungal interactions and are important to S. Typhimurium in order to selectively compete with fungal pathogens. These findings highlight a new role for TTSS of S. Typhimurium in the intestinal tract and may further explain the evolution and maintenance of these traits.

AB Candida dubliniensis is an emerging pathogenic yeast species closely related to Candida albicans and frequently found colonizing or infecting the oral cavities of HIV/AIDS patients. Drug resistance during C. dubliniensis infection is common and constitutes a significant therapeutic challenge. The calcineurin inhibitor FK506 exhibits synergistic fungicidal activity with azoles or echinocandins in the fungal pathogens C. albicans, Cryptococcus neoformans, and Aspergillus fumigatus. In this study, we show that calcineurin is required for cell wall integrity and wild-type tolerance of C. dubliniensis to azoles and echinocandins; hence, these drugs are candidates for combination therapy with calcineurin inhibitors. In contrast to C. albicans, in which the roles of calcineurin and Crz1 in hyphal growth are unclear, here we show that calcineurin and Crz1 play a clearly demonstrable role in hyphal growth in response to nutrient limitation in C. dubliniensis. We further demonstrate that thigmotropism is controlled by Crz1, but not calcineurin, in C. dubliniensis. Similar to C. albicans, C. dubliniensis calcineurin enhances survival in serum. C. dubliniensis calcineurin and crz1/crz1 mutants exhibit attenuated virulence in a murine systemic infection model, likely attributable to defects in cell wall integrity, hyphal growth, and serum survival. Furthermore, we show that C. dubliniensis calcineurin mutants are unable to establish murine ocular infection or form biofilms in a rat denture model. That calcineurin is required for drug tolerance and virulence makes fungus-specific calcineurin inhibitors attractive candidates for combination therapy with azoles or echinocandins against emerging C. dubliniensis infections.

INSULIN-RESISTANCE; WEIGHT-LOSS; BARIATRIC SURGERY; SERUM VISFATIN;
OBESE WOMEN; HEALTHY-MEN; IN-VIVO
AB Objective: Animal and in vitro studies indicate that leptin alleviates starvation-induced reduction in circulating vaspin and stimulates the production of visfatin. We thus examined whether vaspin and visfatin are affected by short-and long-term energy deprivation and leptin administration in human subjects in vivo.
Design and methods: We measured circulating levels of vaspin and visfatin i) before and after 72 h of starvation (leading to severe hypoleptinemia) with or without leptin administration in replacement doses in 13 normal-weight subjects, ii) before and after 72 h of starvation with leptin administration in pharmacological doses in 13 lean and obese subjects, iii) during chronic energy deficiency in eight women with hypothalamic amenorrhea on leptin replacement for 3 months, and iv) during chronic energy deficiency in 18 women with hypothalamic amenorrhea on leptin replacement or placebo for 3 months.
Results: Acute starvation decreased serum leptin to 21% of baseline values, (P=0.002) but had no significant effect on vaspin and visfatin concentrations (P > 0.05). Nor did normalization of leptin levels affect the concentrations of these two adipokines (P > 0.9). Leptin replacement in women with hypothalamic amenorrhea did not significantly alter vaspin and visfatin concentrations, whether relative to baseline or placebo administration (P > 0.25). Pharmacological doses of leptin did not affect circulating vaspin and visfatin concentrations (P > 0.9).
Conclusions: Circulating vaspin and visfatin are not affected by acute or chronic energy deficiency leading to hypoleptinemia and are not regulated by leptin in human subjects, indicating that these adipocyte-secreted hormonal regulators of metabolism are independently regulated in humans.

AB Introduction: The number of microorganism strains with resistance to known antimicrobials is increasing. Therefore, there is a high demand for new, nontoxic and efficient antimicrobial agents. Research with the microscopic nematode Caenorhabditis elegans can address this high demand for the discovery of new antimicrobial compounds. In particular, C. elegans can be used as a model host for in vivo drug discovery through high-throughput screens of chemical libraries.
Areas covered: This review introduces the use of substitute model hosts and especially C. elegans in the study of microbial pathogenesis. The authors also highlight recently published literature on the role of C. elegans in drug discovery and outline its use as a promising host with unique advantages in the discovery of new antimicrobial drugs.
Expert opinion: Caenorhabditis elegans can be used, as a model host, to research many diseases, including fungal infections and Alzheimer's disease. In addition, high-throughput techniques for screening chemical libraries can also be facilitated. Nevertheless, C. elegans and mammals have significant differences that both limit the use of the nematode in research and the degree by which results can be interpreted. That being said, the use of C. elegans in drug discovery still holds promise and the field continues to grow, with attempts to improve the methodology already underway.

AB PALB2 (Partner And Localizer of BRCA2) binds to and co-localizes with BRCA2 in DNA repair. Germline mutations in PALB2 have been identified in approximately 1-2% of familial breast cancer and 3-4% of familial pancreatic cancer cases. The goal of this study was to evaluate the prevalence of PALB2 mutations in women with breast cancer without BRCA1/2 mutations who also had a personal or family history of pancreatic cancer. PALB2 mutation analysis was performed in 94 non-BRCA1/2 breast cancer patients with a personal or family history of pancreatic cancer. Two truncating PALB2 mutations, c.3549C > CA and c.2962C > CT, were identified resulting in a mutation prevalence of 2.1%. The proband found to carry the c.3549C > CA PALB2 mutation had a mother diagnosed with both breast and pancreatic cancer; this relative was subsequently confirmed to carry the identical mutation. The proband with the c.2962C > CT mutation had a father and paternal aunt diagnosed with pancreatic cancer; neither relative was available for testing. Two novel PALB2 missense variants were also found, one of which was deemed potentially deleterious. The prevalence rate of PALB2 mutations in a non-BRCA1/2 breast cancer population specifically selected for a family history of pancreatic cancer does not appear to be significantly increased compared to that observed in other breast cancer populations studied thus far. Further evaluation is needed to determine the prevalence of PALB2 mutations and the clinical utility of such testing in those individuals affected with both breast and pancreatic cancers.

AB The purpose of this study was to examine the "lived experience" of Asian Indian (AI)-White couples in interracial marriages. Ten highly educated AI-White professional couples were individually interviewed about their subjective experience of being in an interracial marriage, the challenges and strengths of this marriage, and the potential role of culture in their marriages. Data were analyzed using the Consensual Qualitative Research methodology. Results indicated that the couples' marital experiences were influenced by a complex intersection of ecosystemic factors with significant psychological impacts. These findings highlight shortcomings in drawing simplistic conclusions regarding the success or failure of an interracial marriage and have important implications for theory, research, and clinical practice.

AB The specialty of Pathology and Laboratory Medicine has entered into a phase when the 4-year sequence of Anatomic Pathology and/or Clinical Pathology Residency Training is almost universally followed by 1 or more years of Subspecialty Fellowship Training. Such training may occur in one of the American Board of Pathology-recognized subspecialties or any number of "subspecialty fellowships" that, although not leading to subspecialty board certification, may nevertheless fall under the oversight of the local institutional Graduate Medical Education Committee and the Accreditation Council for Graduate Medical Education Review Committee for Pathology. Unlike the application process for first-year Pathology Residency, which is run through the National Resident Matching Program, applications for Subspecialty Pathology Fellowships are not coordinated by any consistent schedule. Competition for Subspecialty Pathology Fellowships has consistently resulted in undesirable drift of the fellowship application process to dates that are unacceptably early for many fellowship applicants. Responding to widespread dissatisfaction voiced by national pathology resident organizations, in 2007, the Association of Pathology Chairs began evaluation and potential intervention in the fellowship application process. Three years of intermittently intense discussion, surveys, and market analysis, have led the Council of the Association of Pathology Chairs to recommend implementation of a Pathology Subspecialty Fellowship Matching program starting in the 2011 to 2012 recruiting year, for those Applicants matriculating in fellowship programs July 2013. We report on the data that informed this decision and discuss the pros and cons that are so keenly felt by the stakeholders in this as-yet-incomplete reform process. (C) 2011 Elsevier Inc.

AB To understand the extent to which hospitalized patients participate in their care, and the association of patient participation with quality of care and patient safety.
Random sample telephone survey and medical record review.
US acute care hospitals in 2003.
A total of 2025 recently hospitalized adults.
Hospitalized patients reported participation in their own care, assessments of overall quality of care and the presence of adverse events (AEs) in telephone interviews. Physician reviewers rated the severity and preventability of AEs identified by interview and chart review among 788 surveyed patients who also consented to medical record review.
Of the 2025 patients surveyed, 99.9 of patients reported positive responses to at least one of seven measures of participation. High participation (use of 4 activities) was strongly associated with patients' favorable ratings of the hospital quality of care (adjusted OR: 5.46, 95 CI: 4.157.19). Among the 788 patients with both patient survey and chart review data, there was an inverse relationship between participation and adverse events. In multivariable logistic regression analyses, patients with high participation were half as likely to have at least one adverse event during the admission (adjusted OR 0.49, 0.310.78).
Most hospitalized patients participated in some aspects of their care. Participation was strongly associated with favorable judgments about hospital quality and reduced the risk of experiencing an adverse event.

AB Background: The novel ability to epigenetically reprogram somatic cells into induced pluripotent stem cells (iPSCs) through the exogenous expression of transcription promises to revolutionize the study of human diseases.
Objective: Here we report on the generation of 25 iPSC lines from 6 patients with various forms of primary immunodeficiencies (PIDs) affecting adaptive immunity, innate immunity, or both.
Methods: Patients' dermal fibroblasts were reprogrammed by expression of 4 transcription factors, octamer-binding transcription factor 4 (OCT4), sex determining region Y-box 2 (SOX2), Krueppel-like factor 4 (KLF4), and cellular myelomonocytosis proto-oncogene (cMYC), by using a single excisable polycistronic lentiviral vector.
Results: iPSCs derived from patients with PIDs show a stemness profile that is comparable with that observed in human embryonic stem cells. After in vitro differentiation into embryoid bodies, pluripotency of the patient-derived iPSC lines was demonstrated by expression of genes characteristic of each of the 3 embryonic layers. We have confirmed the patient-specific origin of the iPSC lines and ascertained maintenance of karyotypic integrity.
Conclusion: By providing a limitless source of diseased stem cells that can be differentiated into various cell types in vitro, the repository of iPSC lines from patients with PIDs represents a unique resource to investigate the pathophysiology of hematopoietic and extrahematopoietic manifestations of these diseases and might assist in the development of novel therapeutic approaches based on gene correction.

AB Demyelinating diseases are a group of autoimmune inflammatory disorders affecting the central nervous system in adults and children; however, the diagnosis, evaluation, and treatment of these disorders are primarily based on adult data. The purpose of this study was to assess the practice patterns of US physicians who specialize in treating acquired central nervous system demyelinating diseases in children and adolescents. The Delphi technique was used to identify areas of consensus in management and treatment. Forty-two experts in the field participated in the process. Intravenous methylprednisolone was the first-line treatment of choice for acute episodes of all forms of demyelinating disease; however, consensus was lacking regarding specific dose, treatment duration, and use of an oral taper. First-line disease-modifying therapies for pediatric multiple sclerosis were interferons and glatiramer acetate, chosen based on perceived efficacy and tolerability, respectively. Areas lacking agreement among the expert panel and requiring further research are identified.

AB Cutaneous scalp hemangiomas may herald the presence of occult intracranial hemangiomas. A previously healthy 4-month-old girl presented with a bleeding scalp hemangioma, a bulging fontanel, and anemia. Magnetic resonance imaging (MRI) of the brain revealed hydrocephalus along with multiple intracranial hemangiomas. These lesions compressed the jugular foramina, resulting in venous sinus thrombosis involving the right transverse sinus, the left sigmoid sinus, and the torcular herophili. The patient had no family history of phakomatoses or other genetic abnormalities. A thrombophilia work-up result was unremarkable. The patient was treated with prednisolone (10 mg twice daily) and low molecular weight heparin (1 mg/kg/dose) twice daily. This treatment decreased the size of her cutaneous and intracranial hemangiomas and led to the resolution of her venous sinus thromboses and hydrocephalus. Innocuous scalp hemangioma in an infant may herald more concerning intracranial pathology, which can be treated effectively if diagnosed with appropriate imaging studies.

AB Objective: The aim was to update The Endocrine Society Clinical Practice Guideline on Evaluation and Treatment of Adult Growth Hormone Deficiency (GHD) previously published in 2006.
Consensus Process: Consensus was guided by systematic reviews of evidence and discussions through a series of conference calls and e-mails. An initial draft was prepared by the Task Force, with the help of a medical writer, and reviewed and commented on by members of The Endocrine Society. A second draft was reviewed and approved by The Endocrine Society Council. At each stage of review, the Task Force received written comments and incorporated substantive changes.
Conclusions: GHD can persist from childhood or be newly acquired. Confirmation through stimulation testing is usually required unless there is a proven genetic/structural lesion persistent from childhood. GH therapy offers benefits in body composition, exercise capacity, skeletal integrity, and quality of life measures and is most likely to benefit those patients who have more severe GHD. The risks associated with GH treatment are low. GH dosing regimens should be individualized. The final decision to treat adults with GHD requires thoughtful clinical judgment with a careful evaluation of the benefits and risks specific to the individual.

AB Objective: This report examines what is known about the relationship between obesity and type 2 diabetes and how future research in these areas might be directed to benefit prevention, interventions, and overall patient care.
Research Design and Methods: An international working group of 32 experts in the pathophysiology, genetics, clinical trials, and clinical care of obesity and/or type 2 diabetes participated in a conference held on 6-7 January 2011 and cosponsored by The Endocrine Society, the American Diabetes Association, and the European Association for the Study of Diabetes. A writing group comprising eight participants subsequently prepared this summary and recommendations. Participants reviewed and discussed published literature and their own unpublished data.
Results: The writing group unanimously supported the summary and recommendations as representing the working group's majority or unanimous opinions.
Conclusions: The major questions linking obesity to type 2 diabetes that need to be addressed by combined basic, clinical, and population-based scientific approaches include the following: 1) Why do not all patients with obesity develop type 2 diabetes? 2) Through what mechanisms do obesity and insulin resistance contribute to beta-cell decompensation, and if/when obesity prevention ensues, how much reduction in type 2 diabetes incidence will follow? 3) How does the duration of type 2 diabetes relate to the benefits of weight reduction by lifestyle, weight-loss drugs, and/or bariatric surgery on beta-cell function and glycemia? 4) What is necessary for regulatory approval of medications and possibly surgical approaches for preventing type 2 diabetes in patients with obesity? Improved understanding of how obesity relates to type 2 diabetes may help advance effective and cost-effective interventions for both conditions, including more tailored therapy. To expedite this process, we recommend further investigation into the pathogenesis of these coexistent conditions and innovative approaches to their pharmacological and surgical management.

AB Background: A sustained-release recombinant human GH formulation, LB03002, has been recently developed, with pharmacokinetics and pharmacodynamic activity appropriate for once-weekly administration. LB03002 is a long-acting GH that is administered once a week by sc injection.
Objective: This study evaluated efficacy and safety of LB03002 in adult patients with GH deficiency.
Patients and Methods: A total of 152 patients were randomized to receive LB03002 or placebo once weekly for 26 wk. Changes in body composition were evaluated from DXA (dual-energy x-ray absorptiometry). IGF-I was assessed at each study visit. Safety was assessed from adverse events, glucose homeostasis, and antibody development.
Results: IGF-I increased significantly (P < 0.001) with LB03002 and remained unchanged with placebo. Mean fat mass (FM) decreased by 1.052 kg [95% confidence interval (CI) = -1.614 to -0.491] in the LB03002 group vs. an increase of 0.570 kg (95% CI = -0.205-1.345) in the placebo group; treatment difference was 1.622 kg (95% CI = -2.527 to -0.717; P < 0.001). FM change was mainly due to decreased trunk fat. Least square mean treatment difference was 1.032 kg (95% CI = -1.560 to -0.515; P < 0.001). LBM (lean body mass) was significantly increased with LB03002 vs. placebo (least square mean difference was 1.393 kg; 95% CI = 0.614-2.171; P < 0.001). No concerning safety issues arose during the study.
Conclusions: Weekly GH replacement with the sustained-release preparation LB03002 in adults significantly reduced FM over 6 months and was well tolerated. (J Clin Endocrinol Metab 96: 1718-1726, 2011)

TI Kisspeptin Resets the Hypothalamic GnRH Clock in Men

SECRETION; NEURONS; PUBERTY; INCREASE
AB Context: Reproduction in all mammals is controlled by a hypothalamic clock that produces periodic secretory pulses of GnRH, but how the timing of these pulses is determined is poorly understood. The neuropeptide kisspeptin potently and selectively stimulates the secretion of GnRH. Although this property of kisspeptin is well described, the effects of kisspeptin on endogenous GnRH pulse generation remain largely unexplored.
Objective: The objective of the study was to detail the effects of kisspeptin on GnRH secretion, as reflected by LH secretion, in men.
Participants: Thirteen healthy adult men participated in the study.
Intervention: The intervention was the administration of a single iv bolus of the C-terminal decapeptide of kisspeptin (amino acids 112-121 of the parent protein).
Results: Kisspeptin induced an immediate LH pulse, regardless of the timing of the previous endogenous pulse. The kisspeptin-induced pulses were on average larger than endogenous pulses (amplitude 5.0 +/- 1.0 vs. 2.1 +/- 0.3 mIU/ml, P = 0.02). Comparison of the morphology of kisspeptin-induced LH pulses in healthy men with that of GnRH-induced LH pulses in men with isolated GnRH deficiency suggests that a single iv bolus of kisspeptin triggered sustained GnRH release lasting approximately 17 min. Furthermore, kisspeptin reset the GnRH pulse generator, as it not only induced an immediate LH pulse but also delayed the next endogenous pulse by an interval approximating the normal interpulse interval.
Conclusions: As the first known agent capable of resetting the hypothalamic GnRH pulse generator, kisspeptin can be used as a physiological tool for studying GnRH pulse generation and opens a door to understanding the mechanisms of biological clocks in general.

AB Functional electrical stimulation (FES), the coordinated electrical activation of multiple muscles, has been used to restore arm and hand function in people with paralysis. User interfaces for such systems typically derive commands from mechanically unrelated parts of the body with retained volitional control, and are unnatural and unable to simultaneously command the various joints of the arm. Neural interface systems, based on spiking intracortical signals recorded from the arm area of motor cortex, have shown the ability to control computer cursors, robotic arms and individual muscles in intact non-human primates. Such neural interface systems may thus offer a more natural source of commands for restoring dexterous movements via FES. However, the ability to use decoded neural signals to control the complex mechanical dynamics of a reanimated human limb, rather than the kinematics of a computer mouse, has not been demonstrated. This study demonstrates the ability of an individual with long-standing tetraplegia to use cortical neuron recordings to command the real-time movements of a simulated dynamic arm. This virtual arm replicates the dynamics associated with arm mass and muscle contractile properties, as well as those of an FES feedback controller that converts user commands into the required muscle activation patterns. An individual with long-standing tetraplegia was thus able to control a virtual, two-joint, dynamic arm in real time using commands derived from an existing human intracortical interface technology. These results show the feasibility of combining such an intracortical interface with existing FES systems to provide a high-performance, natural system for restoring arm and hand function in individuals with extensive paralysis.

AB Retinal prostheses aim to restore functional vision to those blinded by outer retinal diseases using electric stimulation of surviving retinal neurons. The ability to replicate the spatiotemporal pattern of ganglion cell spike trains present under normal viewing conditions is presumably an important factor for restoring high-quality vision. In order to replicate such activity with a retinal prosthesis, it is important to consider both how visual information is encoded in ganglion cell spike trains, and how retinal neurons respond to electric stimulation. The goal of the current review is to bring together these two concepts in order to guide the development of more effective stimulation strategies. We review the experiments to date that have studied how retinal neurons respond to electric stimulation and discuss these findings in the context of known retinal signaling strategies. The results from such in vitro studies reveal the advantages and disadvantages of activating the ganglion cell directly with the electric stimulus (direct activation) as compared to activation of neurons that are presynaptic to the ganglion cell (indirect activation). While direct activation allows high temporal but low spatial resolution, indirect activation yields improved spatial resolution but poor temporal resolution. Finally, we use knowledge gained from in vitro experiments to infer the patterns of elicited activity in ongoing human trials, providing insights into some of the factors limiting the quality of prosthetic vision.

AB To improve the quality of prosthetic vision, it is desirable to understand how targeted retinal neurons respond to stimulation. Unfortunately, the factors that shape the response of a single neuron to stimulation are not well understood. A dense band of voltage-gated sodium channels within the proximal axon of retinal ganglion cells is the site most sensitive to electric stimulation, suggesting that band properties are likely to influence the response to stimulation. Here, we examined how three band properties influence sensitivity using a morphologically realistic ganglion cell model in NEURON. Longer bands were more sensitive to short-duration pulses than shorter bands and increasing the distance between band and soma also increased sensitivity. Simulations using the known limits of band length and location resulted in a sensitivity difference of approximately 2. Additional simulations tested how changes to sodium channel conductance within the band influenced threshold and found that the sensitivity difference increased to a factor of nearly 3. This is close to the factor of 5 difference measured in physiological studies suggesting that band properties contribute significantly to the sensitivity differences found between different types of retinal neurons.

AB An electronic retinal prosthesis may provide useful vision for patients suffering from retinitis pigmentosa (RP). In animal models of RP, the amount of current needed to activate retinal ganglion cells (RGCs) is higher than in normal, healthy retinas. In this study, we sought to reduce the stimulation thresholds of RGCs in a degenerate rat model (P23H-line 1) by blocking GABA receptor mediated inhibition in the retina. We examined the effects of TPMPA, a GABA(C) receptor antagonist, and SR95531, a GABA(A) receptor antagonist, on the electrically evoked responses of RGCs to biphasic current pulses delivered to the subretinal surface through a 400 mu m diameter electrode. Both TPMPA and SR95531 reduced the stimulation thresholds of ON-center RGCs on average by 15% and 20% respectively. Co-application of the two GABA receptor antagonists had the greatest effect, on average reducing stimulation thresholds by 32%. In addition, co-application of the two GABA receptor antagonists increased the magnitude of the electrically evoked responses on average three-fold. Neither TPMPA nor SR95531, applied alone or in combination, had consistent effects on the stimulation thresholds of OFF-center RGCs. We suggest that the effects of the GABA receptor antagonists on ON-center RGCs may be attributable to blockage of GABA receptors on the axon terminals of ON bipolar cells.

AB Objectives: The objectives of this study were (1) to compare age at death and the intensity and cost of medical treatment for infants diagnosed prenatally or postnatally with congenital anomalies considered to be lethal. (2) To determine whether greater treatment intensity is associated with longer life.
Study Design: This is a retrospective cohort study of all fetuses and neonates with congenital anomalies classified as lethal who were diagnosed or treated at the University of North Carolina Hospitals from January 1998 to December 2003.
Result: The cohort consisted of 192 fetuses and infants: 160 were diagnosed prenatally, 2 were diagnosed perinatally, and 30 were diagnosed postnatally. In all, 115 (72%) pregnancies were terminated. Of the liveborn infants, 75% died before 10 days of age and 90% before 4 months of age. Compared with postnatally diagnosed infants, prenatally diagnosed infants received less intense treatment (median average daily Neonatal Therapeutic Intervention Scoring System score 8.3 versus 14.0; P = 0.02), at less cost (median direct cost of hospitalization $1550 versus $8474; P = 0.03) and died sooner (median age at death <1 day versus 4 days; P = 0.01). Greater treatment intensity did not correlate with longer survival (r = -0.04; P = 0.66).
Conclusion: Although some kinds of medical therapy may be appropriate for newborns with lethal congenital anomalies, highly aggressive interventions did not prolong survival and should not be offered. Even when pregnancy termination is not elected, infants diagnosed prenatally receive less intense care.

AB This article analyzes interviews with pediatric physicians (N = 30) and chaplains (N = 22) who work at the same large academic medical centers (N = 13). We ask how pediatric physicians understand and work with chaplains and how chaplains describe their own work. We find that physicians see chaplains as part of interdisciplinary medical teams where they perform rituals and support patients and families, especially around death. Chaplains agree but frame their contributions in terms of the perspectives related to wholeness, presence, and healing they bring. Chaplains have a broader sense of what they contribute to patient care than do physicians.

ESTIMATION; DOPPLER ULTRASOUND; CATHETERIZATION; HYPERTENSION; VELOCITY
AB Background: Transthoracic echocardiographic estimates of peak systolic pulmonary artery pressure are conventionally calculated from the maximal velocity of the tricuspid regurgitation (TR) jet. Unfortunately, there is insufficient TR to determine estimated peak systolic pulmonary artery pressure (EPSPAP) in a significant number of patients. To date, in the absence of TR, no noninvasive method of deriving EPSPAP has been developed.
Methods: Five hundred clinically indicated transthoracic echocardiograms were reviewed over a period of 6 months. Patients with pulmonic stenosis were excluded. Pulsed-wave Doppler was used to measure pulmonary artery acceleration time (PAAT) and right ventricular ejection time. Continuous-wave Doppler was used to measure the peak velocity of TR (TR(Vmax)), and EPSPAP was calculated as 4 -TR(Vmax)2 + 10mmHg (to account for right atrial pressure). The relationship between PAAT and EPSPAP was then assessed.
Results: Adequate imaging to measure PAAT was available in 99.6% of patients (498 of 500), but 25.3% (126 of 498) had insufficient TR to determine EPSPAP, and 1 patient had significant pulmonic stenosis. Therefore, 371 were included in the final analysis. Interobserver variability for PAAT was 0.97. There were strong inverse correlations between PAAT and TRVmax (r = -0.96), the right atrial/right ventricular pressure gradient (r = -0.95), and EPSPAP (r = -0.95). The regression equation describing the relationship between PAAT and EPSPAP was log(10)(EPSPAP) = -0.004 (PAAT) + 2.1 (P <.001).
Conclusions: PAAT is routinely obtainable and correlates strongly with both TRVmax and EPSPAP in a large population of randomly selected patients undergoing transthoracic echocardiography. Characterization of the relationship between PAAT and EPSPAP permits PAAT to be used to estimate peak systolic pulmonary artery pressure independent of TR, thereby increasing the percentage of patients in whom transthoracic echocardiography can be used to quantify pulmonary artery pressure.

AB Endometrial carcinoma (EC) is a common female cancer, treated mainly by surgery and adjuvant radiotherapy. Relapse following treatment is associated with increased risk of metastases. Hypoxia, a common microenvironment in solid tumors, correlates with malignant progression, rendering tumors resistant to ionizing therapy. Hence, we assessed here the immunohistochemical expression of hypoxia-inducible factor-1 alpha (HIF-1 alpha) and members of the NF-kappa B family in 82 primary EC and 10 post-radiation recurrences of EC. Post-radiation recurrences were highly hypoxic, with a higher expression of HIF-1 alpha and also RelA (p65) and p52 when compared with primary EC. We next investigated the effects of hypoxia on EC cell lines. We found that EC cell lines are highly resistant to hypoxia-induced apoptosis. We thus focused on the molecular mechanisms involved in conferring hypoxic cell death resistance. We show that in addition to the classical NF-kappa B, hypoxia activates the alternative NF-kappa B pathway. To characterize the upstream kinases involved in the activation of these pathways, we used lentiviral-mediated knockdown and mouse embryonic fibroblasts lacking IKK alpha and IKK beta kinases. Both IKK alpha and IKK beta kinases are required for RelA (p65) and p100 accumulation, whereas p52 processing under hypoxia is IKK alpha dependent. Furthermore, Ishikawa endometrial cell line harboring either RelA (p65) or p52 short-hairpin RNA was sensitive to hypoxia-induced cell death, indicating that, in addition to the known prosurvival role of RelA (p65) under hypoxia, alternative NF-kappa B pathway also enhances hypoxic survival of EC cells. Interestingly, although HIF-1 alpha controlled classical NF-kappa B activation pathway and survival under hypoxia through RelA (p65) nuclear accumulation, the alternative pathway was HIF-1 alpha independent. These findings have important clinical implications for the improvement of EC prognosis before radiotherapy.

TI Neuronal nitric oxide synthase inhibition improves diastolic function

AB Objective: The loss of estrogen in mRen2.Lewis rats leads to an exacerbation of diastolic dysfunction. Because specific neuronal nitric oxide synthase (nNOS) inhibition reverses renal damage in the same model, we assessed the effects of inhibiting neuronal nitric oxide on diastolic function, left ventricular remodeling, and the components of the cardiac nitric oxide system in ovariectomized (OVX) and sham-operated mRen2.Lewis rats treated with N(5)-(1-imino-3-butenyl)-L-ornithine (L-VNIO; 0.5 mg/kg per day for 28 d) or vehicle (saline).
Methods: Female mRen2.Lewis rats underwent either bilateral oophorectomy (OVX; n = 15) or sham operation (or surgical procedure) (sham; n = 19) at 4 weeks of age. Beginning at 11 weeks of age, the rats were randomized to receive either L-VNIO or vehicle.
Results: The surgical loss of ovarian hormones, particularly estrogen, led to exacerbated hypertension, impaired myocardial relaxation, diminished diastolic compliance, increased perivascular fibrosis, and increased relative wall thickness. The cardiac tetrahydrobiopterin-to-dihydrobiopterin levels were lower among OVX rats compared with sham-operated rats, and this altered cardiac biopterin profile was associated with enhanced myocardial superoxide production and decreased nitric oxide release. L-VNIO decreased myocardial reactive oxygen species production, increased nitrite concentrations, attenuated cardiac remodeling, and improved diastolic function.
Conclusions: Impaired relaxation, diastolic stiffness, and cardiac remodeling were found among OVX mRen2.Lewis rats. A possible mechanism for this unfavorable cardiac phenotype may have resulted from a deficiency in available tetrahydrobiopterin and subsequent increase in nNOS-derived superoxide and reduction in nitric oxide synthase metabolites within the heart. Selective nNOS inhibition with L-VNIO attenuated cardiac superoxide production and limited remodeling, leading to improved diastolic function in OVX mRen2.Lewis rats.

AB Protein ubiquitination plays a key role in the regulation of a variety of DNA repair mechanisms. Protein ubiquitination is controlled by the coordinate activity of ubiquitin ligases and deubiquitinating enzymes (DUBs). The deubiquitinating enzyme USP1 regulates DNA repair and the Fanconi anemia pathway through its association with its WD40 binding partner, UAF1, and through its deubiquitination of two critical DNA repair proteins, FANCD2-Ub and PCNA-Ub. To investigate the function of USP1 and UAF1, we generated USP1(-/-), UAF1(-/-/-), and USP1(-/-) UAF1(-/-/-) chicken DT40 cell clones. These three clones showed similar sensitivities to chemical cross-linking agents, to a topoisomerase poison, camptothecin, and to an inhibitor of poly(ADP-ribose) polymerase (PARP), indicating that the USP1/UAF1 complex is a regulator of the cellular response to DNA damage. The hypersensitivity to both camptothecin and a PARP inhibitor suggests that the USP1/UAF1 complex promotes homologous recombination (HR)-mediated double-strand break (DSB) repair. To gain insight into the mechanism of the USP1/UAF1 complex in HR, we inactivated the nonhomologous end-joining (NHEJ) pathway in UAF1-deficient cells. Disruption of NHEJ in UAF1-deficient cells restored cellular resistance to camptothecin and the PARP inhibitor. Our results indicate that the USP1/UAF1 complex promotes HR, at least in part by suppressing NHEJ.

HERITABILITY; POPULATION
AB We estimate and partition genetic variation for height, body mass index (BMI), von Willebrand factor and QT interval (QTi) using 586,898 SNPs genotyped on 11,586 unrelated individuals. We estimate that similar to 45%, similar to 17%, similar to 25% and similar to 21% of the variance in height, BMI, von Willebrand factor and QTi, respectively, can be explained by all autosomal SNPs and a further similar to 0.5-1% can be explained by X chromosome SNPs. We show that the variance explained by each chromosome is proportional to its length, and that SNPs in or near genes explain more variation than SNPs between genes. We propose a new approach to estimate variation due to cryptic relatedness and population stratification. Our results provide further evidence that a substantial proportion of heritability is captured by common SNPs, that height, BMI and QTi are highly polygenic traits, and that the additive variation explained by a part of the genome is approximately proportional to the total length of DNA contained within genes therein.

AB Next-generation sequencing has not been applied to protein-protein interactome network mapping so far because the association between the members of each interacting pair would not be maintained in en masse sequencing. We describe a massively parallel interactome-mapping pipeline, Stitch-seq, that combines PCRCR stitching with next-generation sequencing and used it to generate a new human interactome dataset. Stitch-seq is applicable to various interaction assays and should help expand interactome network mapping.

conflict; composite paradigm, temporal information processing
ID TIME-COURSE ANALYSIS; RECOGNITION; PERCEPTION; INTERFERENCE
AB We examined whether temporal integration of face parts reflects holistic processing or response interference. Participants learned to name two faces "Fred" and two "Bob." At test, the top and bottom halves of different faces formed composites and were presented briefly separated in time. Replicating prior findings (Singer & Sheinberg, Vision Research, 46, 1838-1847, 2006), naming of the target half for aligned composites was slowed when the irrelevant half was from a face with a different name rather than from the original face. However, no interference was observed when the irrelevant half had a name identical to the name of the target half but came from a different learned face, arguing against a true holistic effect. Instead, response interference was obtained when the target half briefly preceded the irrelevant half. Experiment 2 confirmed a double dissociation of holistic processing versus response interference for intact faces versus temporally separated face halves, suggesting that simultaneous presentation of facial information is critical for holistic processing.

AB Purpose: To evaluate 14-week effects of intravitreal ranibizumab or triamcinolone in eyes receiving focal/grid laser for diabetic macular edema and panretinal photocoagulation.
Methods: Three hundred and forty-five eyes with a visual acuity of 20/320 or better, center-involved diabetic macular edema receiving focal/grid laser, and diabetic retinopathy receiving prompt panretinal photocoagulation were randomly assigned to sham (n = 123), 0.5-mg ranibizumab (n = 113) at baseline and 4 weeks, and 4-mg triamcinolone at baseline and sham at 4 weeks (n = 109). Treatment was at investigator discretion from 14 weeks to 56 weeks.
Results: Mean changes (+/-SD) in visual acuity letter score from baseline were significantly better in the ranibizumab (+1 +/- 11; P < 0.001) and triamcinolone (+2 +/- 11; P, 0.001) groups compared with those in the sham group (24 +/- 14) at the 14-week visit, mirroring retinal thickening results. These differences were not maintained when study participants were followed for 56 weeks for safety outcomes. One eye (0.9%; 95% confidence interval, 0.02%-4.7%) developed endophthalmitis after receiving ranibizumab. Cerebrovascular/cardiovascular events occurred in 4%, 7%, and 3% of the sham, ranibizumab, and triamcinolone groups, respectively.
Conclusion: The addition of 1 intravitreal triamcinolone injection or 2 intravitreal ranibizumab injections in eyes receiving focal/grid laser for diabetic macular edema and panretinal photocoagulation is associated with better visual acuity and decreased macular edema by 14 weeks. Whether continued long-term intravitreal treatment is beneficial cannot be determined from this study. RETINA 31: 1009-1027, 2011

AB Purpose: The PKC-DRS2 was a Phase 3, randomized, double-masked, placebo (PBO)controlled, 3-year study of the effect of 32 mg/day of ruboxistaurin (RBX), an orally administered protein kinase C inhibitor, on vision loss in patients with moderate to severe nonproliferative diabetic retinopathy. Ruboxistaurin reduced the occurrence of sustained moderate visual loss (SMVL; >15-letter decline in visual acuity sustained for the last 6 months of study participation) from 9.1% in the PBO group (N = 340) to 5.5% in the RBX group (N = 345, P = 0.034). This study evaluates the primary end point of SMVL in a 2-year open-label extension (OLE) of the PKC-DRS2, which began a median of 466 days (range, 263-1,296 days) after the conclusion of PKC-DRS2.
Methods: Visual acuity was measured by certified examiners using the Early Treatment Diabetic Retinopathy Study chart.
Results: Of the 514 patients who completed PKC-DRS2, 366 did so in the 32 study centers participating in the OLE, and of these, 203 (55%) enrolled in the OLE for treatment with 32 mg/day of RBX for 2 years. Of the 203 enrolled in the OLE, 100 had previously been treated with PBO (prior PBO subgroup) and 103 had been treated with RBX (prior RBX subgroup). PKC-DRS2 baseline patient and ocular characteristics were well matched between these two subgroups and were similar to the PKC-DRS2 patient population as a whole. Using the PKC-DRS2 baseline as the starting point, SMVL occurred in 6% of the prior PBO subgroup during the PKC-DRS2, increasing to 26% by the end of the OLE. However, in the prior RBX subgroup, SMVL occurred in only 4% and 8% during the PKC-DRS2 and by the end of the OLE, respectively (P < 0.001 for difference at the end of the OLE). In the prior PBO subgroup, mean visual acuity declined from 79.6 letters at PKC-DRS2 baseline to 73.1 letters at OLE end point (26.5 letters). In the prior RBX subgroup, this loss was 2.7 letters (79.8 to 77.1) over the same period (P = 0.02).
Conclusion: Over a 6-year study period incorporating 3 years of a rigorously placebo-controlled trial, approximately 1 year off treatment and 2-year OLE where all groups received therapy, those patients with greatest RBX exposure (similar to 5 years) experienced less SMVL compared with those in the original PBO group (similar to 2-year RBX exposure).

AB Background and Purpose-Central nervous system vascular malformations (VMs) result from abnormal vasculo-and/or angiogenesis. Cavernomas and arteriovenous malformations are also sites of active inflammation. The aim of this study was to determine whether MRI detection of VMs can be improved by administration of ferumoxytol iron oxide nanoparticle, which acts as a blood pool agent at early time points and an inflammatory marker when taken up by tissue macrophages.
Methods-Nineteen patients (11 men, 8 women; mean age, 47.5 years) with central nervous system VMs underwent 3-T MRI both with gadoteridol and ferumoxytol. The ferumoxytol-induced signal changes on the T1-, T2-, and susceptibility-weighted images were analyzed at 25 minutes (range, 21 to 30 minutes) and 24 hours (range, 22 to 27 hours).
Results-Thirty-five lesions (capillary telangiectasia, n = 6; cavernoma, n = 21; developmental venous anomaly, n = 7; arteriovenous malformation, n = 1) were seen on the pre- and postgadoteridol images. The postferumoxytol susceptibility-weighted sequences revealed 5 additional VMs (3 capillary telangiectasias, 2 cavernomas) and demonstrated further tributary veins in all patients with developmental venous anomalies. The 24-hour T1 and T2 ferumoxytol-related signal abnormalities were inconsistent among patients and within VM types. No additional area of T1 or T2 enhancement was noted with ferumoxytol compared with gadoteridol in any lesion.
Conclusions-Our findings indicate that the blood pool agent ferumoxytol provides important information about the number and true extent of VMs on the susceptibility-weighted MRI. The use of ferumoxytol as a macrophage imaging agent in the visualization of inflammatory cells within and around the lesions warrants further investigation. (Stroke. 2011;42:1581-1588.)

AB OBJECTIVES To investigate clinical outomes, bacterial virulence factors, and antimicrobial resistance in E. coli from young men presenting with acute bacterial prostatitis.
METHODS Initial E. coli isolates from previously healthy young men with no factors compromising urinary tract anatomy or function were tested for virulence-associated genes by polymerase chain reaction (PCR) assays, phylogenetic grouping by triplex polymerase PCR, and antibiotic resistance.
RESULTS All 18 patients responded to treatment, including 2 who required long-term therapy. E. coli were allocated to phylogenetic groups B2 (13 strains) and D (5 strains). Prostatitis isolates belonged to clones mainly represented by extraintestinal pathogenic E. coli (ExPEC) and preferentially uropathogenic E. coli and displayed marked accumulation of virulence genes (hly, cdt1, clb, pap, sfa/foc, fyuA, iroN, kpsMT(II), and traT) characteristic of highly virulent ExPEC. All phylogenetic group B2 strains coded for at least 1 toxin with carcinogenic potential (Colibactin, cytolethal distending toxins, or cytotoxic necrotizing factor). In contrast to their accumulation of virulence-associated traits, prostatitis strains were sensitive to standard antibiotics.
CONCLUSIONS The phylogenetic background and accumulation of an exceptional repertoire of extraintestinal pathogenic virulence-associated genes indicate that these E. coli strains belong to a highly virulent subset of uropathogenic variants. In contrast, antibiotic resistance was minimal in these E. coli strains from previously healthy, young outpatients. UROLOGY 77: 1420-1425, 2011. Published by Elsevier Inc.

AB Background:
At least 60% of those treated for an alcohol use disorder will relapse. Empirical study of the integrity of the brain reward system (BRS) is critical to understanding the mechanisms of relapse as this collection of circuits is implicated in the development and maintenance of all forms of addictive disorders. This study compared thickness, surface area, and volume in neocortical components of the BRS among nonsmoking light-drinking controls (controls), individuals who remained abstinent and those who relapsed after treatment.
Methods:
Seventy-five treatment-seeking alcohol-dependent individuals (abstinent for 7 +/- 3 days) and 43 controls completed 1.5T proton magnetic resonance imaging studies. Parcellated morphological data were obtained for following bilateral components of the BRS: rostral and caudal anterior cingulate cortex, insula, medial and lateral orbitofrontal cortex (OFC), rostral and caudal middle and superior frontal gyri, amygdala and hippocampus as well as for 26 other bilateral neocortical regions. Alcohol-dependent participants were followed over 12-months after baseline study and were classified as abstainers (no alcohol consumption; n = 24) and relapsers (any alcohol consumption; n = 51) at follow-up.
Results:
Relapsers and abstainers demonstrated lower cortical thickness in the vast majority of BRS regions as well as lower global thickness compared to controls. Relapsers had lower total BRS surface area than both controls and abstainers, but abstainers were not significantly different from controls on any surface area measure. Relapsers demonstrated lower volumes than controls in the majority of regions, while abstainers showed lower volumes than controls in the superior frontal gyrus, insula, amygdala, and hippocampus, bilaterally. Relapsers exhibited smaller volumes than abstainers in the right rostral middle and caudal middle frontal gyri and the lateral OFC, bilaterally. In relapsers, lower baseline volumes and surface areas in multiple regions were associated with a greater magnitude of post-treatment alcohol consumption.
Conclusions:
Results suggest relapsers demonstrated morphological abnormalities in regions involved in the "top down" regulation/modulation of internal drive states, emotions, reward processing, and behavior, which may impart increased risk for the relapse/remit cycle that afflicts many with an alcohol use disorder. Results also highlight the importance of examining both cortical thickness and surface area to better understand the nature of regional volume loss frequently observed in alcohol use disorders. Results from this report are consistent with previous research implicating plastic neurobiological changes in the BRS in the maintenance of addictive disorders.

AB Objectives: Progression of Alzheimer dementia (AD) is highly variable. Most estimates derive from convenience samples from dementia clinics or research centers where there is substantial potential for survival bias and other distortions. In a population-based sample of incident AD cases, we examined progression of impairment in cognition, function, and neuropsychiatric symptoms, and the influence of selected variables on these domains. Design: Longitudinal, prospective cohort study. Setting: Cache County (Utah). Participants: Three hundred twenty-eight persons with a diagnosis of possible/probable AD. Measurements: Mini-Mental State Exam (MMSE), Clinical Dementia Rating sum-of-boxes (CDR-sb), and Neuropsychiatric Inventory (NPI). Results: Over a mean follow-up of 3.80 (range: 0.07-12.90) years, the mean (SD) annual rates of change were -1.53 (2.69) scale points on the MMSE, 1.44 (1.82) on the CDR-sb, and 2.55 (5.37) on the NPI. Among surviving participants, 30% to 58% progressed less than 1 point per year on these measures, even 5 to 7 years after dementia onset. Rates of change were correlated between MMSE and CDR-sb (r = -0.62, df = 201, p < 0.001) and between the CDR-sb and NPI (r = 0.20, df = 206, p < 0.004). Female subjects (LR chi(2) = 8.7, df = 2, p = 0.013) and those with younger onset (likelihood ratio [LR] chi(2) = 5.7, df = 2, p = 0.058) declined faster on the MMSE. Although one or more apolipoprotein E epsilon 4 alleles and ever use of FDA-approved antidementia medications were associated with initial MMSE scores, neither was related to the rate of progression in any domain. Conclusions: A significant proportion of persons with AD progresses slowly. The results underscore differences between population-based versus clinic-based samples and suggest ongoing need to identify factors that may slow the progression of AD.

AB Objectives: To describe preloss and postloss grief symptoms among family members of nursing home (NH) residents with advanced dementia, and to identify predictors of greater postloss grief symptoms. Design: Prospective cohort study. Setting: 22 NHs in the greater Boston area. Participants: 123 family members of NH residents who died with advanced dementia. Measurements: Preloss grief was measured at baseline, and postloss grief was measured 2 and 7 months postloss using the Prolonged Grief Disorder Scale. Independent variables included resident and family member sociodemographic characteristics, resident comfort, acute illness, acute care prior to death, family member depression, and family member understanding of dementia and of resident's prognosis. Results: Levels of preloss and postloss grief were relatively stable from baseline to 7 months postloss. Feelings of separation and yearning were the most prominent grief symptoms. After multivariable adjustment, greater preloss grief and the family member having lived with the resident prior to NH admission were the only factors independently associated with greater postloss grief 7 months after resident death. Conclusions: The pattern of grieving for some family members of NH residents with advanced dementia is prolonged and begins before resident death. Identification of family members at risk for postloss grief during the preloss period may help guide interventions aimed at lessening postloss grief. (Am J Geriatr Psychiatry 2011; 19:543-550)

TI Laboratory testing for cryoglobulins
SO AMERICAN JOURNAL OF HEMATOLOGY
LA English
DT Article
ID HEPATITIS-C VIRUS; MIXED CRYOGLOBULINEMIA; RITUXIMAB; EFFICACY; DISEASE;
SAFETY
AB Cryoglobulins are immunoglobulins that precipitate below 37 degrees C and can cause multiorgan damage. There are three types of cryoglobulins: Type I (also called simple), which is mostly associated with monoclonal gammopathy and/or other hematologic disorders and Type II and Type III (known as mixed cryoglobulins), which are associated with infectious and systemic diseases. Testing for cryoglobulins is complicated by lack of reference range, standards, and stringency in maintaining testing temperature conditions. Identification of cryoprecipitate can be critical for patient care; therefore, correct testing conditions are crucial for reliable cryoglobulin testing. The patient's blood sample should be kept at 37 degrees C initially to avoid premature precipitation of cryoglobulins and thereby decreasing the yield for subsequent identification. This could cause a false negative result. After warm centrifugation or warm cell precipitation, the clear serum is observed at 4 degrees C for formation of cryoprecipitate. The cryoprecipitate is then washed in cold buffer, and the resulting precipitate is warmed to 37 degrees C and subjected to further analysis by immunodiffusion and immunofixation. In addition to Meltzer's triad of purpura, weakness and arthralgias, cryoglobulinemias have protean manifestations involving skin, joints, kidney, nervous system, as well as the hematopoietic system. The management of cryoglobulinemia especially in patients with organ damage remains difficult. Treatment of cryoglobulinemia focuses on management of the underlying lymphoproliferative disorder or infectious or systemic causes. Medical management may also include corticosteroids and other immunosuppressive agents and plasmapheresis. Rituximab therapy seems to abrogate the aberrant B cell response. Am. J.

AB As recently as the 1970s, children born with sickle cell disease (SCD) were unlikely to survive into adulthood. With advances in medical care, most patients now survive childhood and live into their forties or beyond [1,2]. A better transition from pediatric- to adult-focused care is therefore increasingly important [3]. Despite recent awareness of the importance of transition by the SCD community, little is known about existing transition programs. We conducted a survey of pediatric sickle cell clinics to describe current transition practices and identify areas for improvement. Survey topics included program demographics, transition logistics, assessment of patient transition readiness and independence, transition preparation, and program evaluation. Twenty-three clinics (77%) report having a transition program, although half have been in place for under 2 years. There is wide variation in specific transition practices. Most centers (97%) have an identified accepting adult provider, however, only 60% routinely transfer their patients to an adult hematologist specializing in SCD. Although there has been a recent effort to establish transition programs in pediatric sickle cell clinics, specific practices vary widely. As anticipated, lack of an accepting adult hematologist with an interest in SCD emerged as a common barrier to transition.

TI Lower Urinary Connective Tissue Growth Factor Levels and Incident CKD
Stage 3 in the General Population

FACTOR EXCRETION; UNITED-STATES; EXPRESSION; PREVALENCE
AB Background: Connective tissue growth factor (CTGF) is involved in the development and progression of kidney diseases, including diabetic nephropathy and kidney fibrosis, but also may have a role in mesangial repair after injury. It is unknown whether, in the general population, urinary CTGF levels are associated with a decrease in estimated glomerular filtration rate (eGFR) to <60 mL/min/1.73 m(2) (ie, development of chronic kidney disease [CKD] stage 3).
Study Design: Nested case-control.
Setting & Participants: 100 cases of incident CKD stage 3 and 100 age-and sex-matched controls in the Framingham Heart Study; 141 cases and 135 age-, sex-, and race-matched controls in the Atherosclerosis Risk in Communities (ARIC) Study. Controls had eGFR >= 60 mL/min/1.73 m(2) at follow-up in both studies.
Predictors: Urinary CTGF concentrations.
Outcomes: Incident CKD stage 3, defined as eGFR <60 mL/min/1.73 m(2).
Measurements: Stored urine samples from Framingham Heart Study and ARIC were measured for CTGF. Covariates were obtained from Framingham Heart Study and ARIC participant examinations.
Results: In the Framingham Heart Study, the median baseline urinary CTGF concentration was lower in cases (1.35 ng/mL) than controls (2.35 ng/mL; paired t test, P < 0.0001). The multivariable-adjusted OR for incident CKD stage 3 was 0.33 (95% CI, 0.17-0.64; P < 0.001) per 1-standard deviation in log urinary CTGF level after adjustment for CKD risk factors, baseline eGFR, and baseline log urinary albumin-creatinine ratio, with similar results in participants without diabetes (n = 184). Results were not materially different when urinary CTGF level was indexed to urinary creatinine level (multivariable-adjusted OR, 0.34; 95% CI, 0.21-0.56; P < 0.001). A similar, but nonsignificant, trend of risk of incident CKD stage 3 with lower baseline urinary CTGF concentration was observed in an independent case-control study conducted in the ARIC Study, with the strongest results observed in participants free of diabetes. This inverse relationship was robust in meta-analysis of both the overall and diabetes-free groups.
Limitations: Observational study; causality cannot be inferred.
Conclusions: Lower urinary CTGF concentrations precede the onset of CKD stage 3 in the general population. Further work is required to fully characterize how CTGF level influences risk of CKD.

AB Issues of multiple-testing and statistical significance in genome-wide association studies (GWAS) have prompted statistical methods utilizing prior data to increase the power of association results. Using prior findings from genome-wide linkage studies on bipolar disorder (BPD), we employed a weighted false discovery approach (wFDR; [Roeder et al. 2006. Am J Hum Genet 78(2): 243-252]) to previously reported GWAS data drawn from the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD). Using this method, association signals are up or down-weighted given the linkage score in that genomic region. Although no SNPs in our sample reached genome-wide significance through the wFDR approach, the strongest single SNP result from the original GWAS results (rs4939921 in myosin VB) is strongly up-weighted as it occurs on a linkage peak of chromosome 18. We also identify regions on chromosome 9, 17, and 18 where modestly associated SNP clusters coincide with strong linkage scores, implicating them as possible candidate regions for further analysis. Moving forward, we believe the application of prior linkage information will be increasingly useful to future GWAS studies that incorporate rarer variants into their analysis.

AB SLC1A1 encodes a neuronal glutamate transporter and is a promising candidate gene for obsessive-compulsive disorder (OCD). Several independent research groups have reported significant associations between OCD and single nucleotide polymorphisms (SNPs) in this gene. Previously, we evaluated 13 SNPs in, or near, SLC1A1 and reported a strong association signal with rs301443, a SNP 7.5 kb downstream of the gene [Shugart et al. (2009); Am J Med Genet Part B 150B:886-892]. Theaims of the current study were first, to further investigate this finding by saturating the region around rs301443; and second, to explore the entire gene more thoroughly with a dense panel of SNP markers. We genotyped an additional 111 SNPs in or near SLC1A1, covering from 9 kb upstream to 84 kb downstream of the gene at average spacing of 1.7 kb per SNP, and conducted family-based association analyses in 1,576 participants in 377 families. We found that none of the surrounding markers were in linkage disequilibrium with rs301443, nor were any associated with OCD. We also found that SNP rs4740788, located about 8.8 kb upstream of the gene, was associated with OCD in all families (P = 0.003) and in families with male affecteds (P = 0.002). A three-SNP haplotype (rs4740788-rs10491734-rs10491733) was associated with OCD in the total sample (P = 0.00015) and in families with male affecteds (P = 0.0007). Although of nominal statistical significance considering the number of comparisons, these findings provide further support for the involvement of SLC1A1 in the pathogenesis of OCD.

AB BACKGROUND: Concerns have been raised about the risk of fractures with acid-suppressive medications, such as proton pump inhibitors and histamine(2)-receptor antagonists.
METHODS: This meta-analysis evaluated the association between proton pump inhibitor or histamine(2)-receptor antagonist use and fractures. We performed a systematic search of published literature (1970 to October 10, 2010) in MEDLINE, EMBASE, and other sources. Ten publications reporting 11 studies were considered eligible for analysis.
RESULTS: All studies were observational case-control or cohort studies and primarily evaluated older adults. The summary effect estimate for risk of hip fracture increased modestly among individuals taking proton pump inhibitors (relative risk [RR] 1.30, 95% confidence interval [CI], 1.19-1.43). There also was an increase in spine (RR 1.56, 95% CI, 1.31-1.85) and any-site fractures (RR 1.16, 95% CI, 1.04-1.30) among proton pump inhibitor users. These findings were similar in both men and women and after stratification by duration of use. In contrast, histamine(2)-receptor antagonist use was not significantly associated with increased risk of hip fracture (RR 1.12, 95% CI, 0.97-1.30).
CONCLUSION: In this meta-analysis of observational studies, proton pump inhibitors modestly increased the risk of hip, spine, and any-site fractures, whereas histamine(2)-receptor antagonists were not associated with fracture risk. The possibility of residual confounding cannot be excluded. Further skeletal evaluation should be considered for patients who are taking proton pump inhibitors and also at risk for osteoporotic fracture. (C) 2011 Elsevier Inc. All rights reserved.

AB OBJECTIVE. This article will illustrate and describe the spectrum of diseases associated with air cysts at high-resolution CT (HRCT).
CONCLUSION. HRCT is an important modality in the evaluation of interstitial lung disease to include cystic lung disease. Although most commonly associated with lymphangioleiomyomatosis or Langerhans cell histiocytosis, cystic lung disease is increasingly being recognized as a feature of other entities. Awareness of the spectrum of HRCT findings associated with these diseases may help the trained observer narrow the differential diagnosis.

AB OBJECTIVE. The purpose of this study was to evaluate the image quality and diagnostic performance of low-dose MDCT and CT enterography with adaptive statistical iterative reconstruction (ASIR) in the evaluation of Crohn disease.
SUBJECTS AND METHODS. Forty-eight patients (20 men, 28 women; mean age, 33.3 years; range, 17-83 years) with known or suspected Crohn disease who underwent low-dose MDCT and CT enterography with ASIR between December 2008 and December 2009 were included in the study. Twenty-seven patients had previously undergone standard-dose 64-MDCT and CT enterography with filtered back projection (FBP), and those images were used for comparison. The weight-based IV contrast protocol and scan parameters (120 kVp, 5-mm section thickness, 0.5-second rotation, pitch of 1.375, 64 x 0.625 mm detector configuration) were constant for the two techniques except for a higher noise index (x1.3) in the ASIR group. Two blinded readers reviewed 75 randomized MDCT-CT enterographic scans of 48 patients to assess image quality and diagnostic performance in the evaluation of Crohn disease, and the radiation dose for the studies was estimated.
RESULTS. All 75 MDCT and CT enterographic scans had acceptable quality for diagnostic interpretation. Findings of Crohn disease were seen on 63 of 75 scans (84%). Low-dose scans in the ASIR group had optimal image quality and were rated comparable to or better than standard-dose FBP images (mean score, 4.2 vs 3.87; p = 0.007). The subjective image noise score (mean, 1.43 vs 1.58; p = 0.2) and objective image noise measurements were lower for ASIR images (p < 0.001). Low-dose studies with ASIR allowed average dose reduction of 34.5% compared with standard-dose scans with FBP (volume CT dose index for ASIR, 7.7 +/- 2.1 mGy; for FBP, 12 +/- 5.5 mGy; p < 0.01).
CONCLUSION. Low-dose MDCT and CT enterographic studies reconstructed with ASIR were of appropriate quality for confident evaluation of the manifestations of Crohn disease while allowing approximately 34% dose reduction in comparison with FBP technique.

AB Objective: To describe our series of distal pancreatectomies with preservation of the spleen utilizing the Warshaw operation with a focus on possible long-term complications due to the development of gastric varices.
Background: The Warshaw operation was first described in 1988. The splenic vessels are resected and the spleen survives via the short gastric and left gastroepiploic vessels.
Methods: Retrospective review of 721 patients who underwent a distal pancreatectomy between February 1986 and February 2009.
Results: The spleen was preserved via the Warshaw operation in 158 patients (22%). Median age was 55 years (range 10-85) and 72% were females. Pathologies included: 35 mucinous cystic neoplasms (adenoma 28, borderline 7), 22 intraductal papillary mucinous neoplasms (adenoma 9, borderline 9, cancer 4), 23 serous cystadenomas, 13 other pancreatic cysts, 27 pancreatic endocrine tumors, 16 chronic pancreatitis, 9 ductal adenocarcinomas, and 13 other pathologies. Only 3 (1.9%) patients required a reoperation because of splenic infarction at 3 to 100 days postoperatively because of abdominal pain and/or fever. Median follow-up was 2.7 years (mean 4.5 years, range 0-21 years). There was evidence of perigastric varices in 16 of 65 (25%) patients who had follow-up imaging at a median of 3.4 years, but none of the 158 patients developed gastrointestinal bleeding or hypersplenism.
Conclusions: Spleen preservation with the Warshaw operation has a low postoperative failure rate of 1.9%. Radiologic evidence of asymptomatic perigastric varices was identified in 25% of patients. There were no clinical consequences of perigastric varices in any patient during a follow-up period of up to 21 years.

AB This study characterizes aminoindole molecules that are analogs of Genz-644442. Genz-644442 was identified as a hit in a screen of similar to 70,000 compounds in the Broad Institute's small-molecule library and the ICCB-L compound collection at Harvard Medical School. Genz-644442 is a potent inhibitor of Plasmodium falciparum in vitro (50% inhibitory concentrations [IC(50)s], 200 to 285 nM) and inhibits P. berghei in vivo with an efficacy of > 99% in an adapted version of Peters' 4-day suppressive test (W. Peters, Ann. Trop. Med. Parasitol. 69: 155-171, 1975). Genz-644442 became the focus of medicinal chemistry optimization; 321 analogs were synthesized and were tested for in vitro potency against P. falciparum and for in vitro absorption, distribution, metabolism, and excretion (ADME) properties. This yielded compounds with IC(50)s of approximately 30 nM. The lead compound, Genz-668764, has been characterized in more detail. It is a single enantiomer with IC(50)s of 28 to 65 nM against P. falciparum in vitro. In the 4-day P. berghei model, when it was dosed at 100 mg/kg of body weight/day, no parasites were detected on day 4 postinfection. However, parasites recrudesced by day 9. Dosing at 200 mg/kg/day twice a day resulted in cures of 3/5 animals. The compound had comparable activity against P. falciparum blood stages in a humanengrafted NOD-scid mouse model. Genz-668764 had a terminal half-life of 2.8 h and plasma trough levels of 41 ng/ml when it was dosed twice a day orally at 55 mg/kg/day. Seven-day rat safety studies showed a no-observableadverse- effect level (NOAEL) at 200 mg/kg/day; the compound was not mutagenic in Ames tests, did not inhibit the hERG channel, and did not have potent activity against a broad panel of receptors and enzymes. Employing allometric scaling and using in vitro ADME data, the predicted human minimum efficacious dose of Genz-668764 in a 3-day once-daily dosing regimen was 421 mg/day/70 kg, which would maintain plasma trough levels above the IC(90) against P. falciparum for at least 96 h after the last dose. The predicted human therapeutic index was approximately 3, on the basis of the exposure in rats at the NOAEL. We were unable to select for parasites with > 2-fold decreased sensitivity to the parent compound, Genz-644442, over 270 days of in vitro culture under drug pressure. These characteristics make Genz-668764 a good candidate for preclinical development.

AB We previously demonstrated that inhaling nitric oxide (NO) increases the oxygen affinity of sickle red blood cells (RBCs) in patients with sickle cell disease (SCD). Our recent studies found that NO lowered the P(50) values of sickle hemoglobin (HbS) hemolysates but did not increase methemoglobin (metHb) levels, supporting the role of NO, but not metHb, in the oxygen affinity of HbS. Here we examine the mechanism by which NO increases HbS oxygen affinity. Because anti-sickling agents increase sickle RBC oxygen affinity, we first determined whether NO exhibits anti-sickling properties. The viscosity of HbS hemolysates, measured by falling ball assays, increased upon deoxygenation: NO treatment reduced the increment. Multiphoton microscopic analyses showed smaller HbS polymers in deoxygenated sickle RBCs and HbS hemolysates exposed to NO. These results suggest that NO inhibits HbS polymer formation and has anti-sickling properties. Furthermore, we found that HbS treated with NO exhibits an isoelectric point similar to that of HbA, suggesting that NO alters the electric charge of HbS. NO HbS adducts had the same elution time as HbA upon high performance liquid chromatography analysis. This study demonstrates that NO may disrupt HbS polymers by abolishing the excess positive charge of HbS, resulting in increased oxygen affinity. (C) 2011 Elsevier Inc. All rights reserved.

AB Intimate partner violence (IPV) exposure was examined as a predictor of treatment engagement (i.e., starting and completing therapy) and treatment outcome in 150 women taking part in a dismantling study of cognitive processing therapy (CPT) for posttraumatic stress disorder (PTSD; Resick et al., 2008). Results indicate that women in a current intimate relationship with recent IPV (i.e., past year) were less likely to begin treatment relative to women who reported past IPV only or no history of IPV. For women who began treatment, IPV exposure was not predictive of whether or not they completed treatment. Among women who began treatment, the frequency of IPV was associated with treatment outcome such that women who experienced more frequent IPV exhibited larger reductions in PTSD and depression symptoms over the course of treatment, but experienced similar levels of PTSD and depression severity at the 6-month follow-up. Findings highlight the importance of targeting treatment engagement among women who report recent IPV and suggest that women who have experienced frequent IPV respond well to CPT treatment in spite of their IPV experiences.

AB Recent research has focused on the effectiveness of evidence-based psychotherapy delivered via telehealth services. Unfortunately to date, the majority of studies employ very small samples and limited predictor and moderator variables. To address these concerns and further replicate and extend the literature on telehealth, the present study investigated the effectiveness of 12-session exposure therapy delivered either via telehealth (n=62) or in person (n=27) in veterans with posttraumatic stress disorder (PTSD). Findings demonstrated that although older veterans and Vietnam veterans were more likely to complete the telehealth treatment, telehealth findings were not influenced by patient age, sex, race, combat theater, or disability status. Exposure therapy delivered via telehealth was effective in reducing the symptoms of PTSD, anxiety, depression, stress, and general impairment with large effect sizes. Interestingly, exposure therapy via telehealth was less effective than exposure therapy delivered in person; however, lack of random assignment to condition limits conclusions of differential effectiveness. Overall, these findings support the utility of telehealth services to provide effective, evidence-based psychotherapies.

AB OBJECTIVE
To characterize factors associated with positive surgical margins (PSMs) and derive population-based PSM cutoffs to evaluate surgeon performance in radical prostatectomy (RP).
PATIENTS AND METHODS
SEER-Medicare data were used to identify 4247 men diagnosed with prostate cancer during 2004-2005 who underwent RP up to 2006.
We performed logistic regression to assess the impact of tumour characteristics, surgeon volume and surgical approach on the likelihood of PSMs for pT2 and PT3a disease.
Moreover, we derived 25th and 10th percentile cutoffs from binomial distribution equations.
RESULTS
Overall, 19.4% of men experienced PSMs with a pT2 vs pT3a PSM rate of 14.9% vs 42% (P < 0.001). Extrapolating from our population-based results, a surgeon incurring more than three PSMs in 10 cases of pT2 disease performed below the 25th percentile.
There was a trend for fewer PSMs with minimally invasive vs open RP (17.4% vs 20.1%, P = 0.086), and the PSM rate also decreased over the study period from 21.3% in 2004 to 16.6% in 2006 (P = 0.028) with significant geographic variation (P < 0.001).
In adjusted analyses, temporal and geographic variation in PSM persisted, and men with high (odds ratio 3.68, 95% CI 2.82-4.81) and intermediate (odds ratio 2.52, 95% CI 2.03-3.13) vs low-risk disease were at greater odds to experience PSMs. Notably, neither surgical approach nor surgeon volume was significantly associated with PSMs.
CONCLUSION
Our population-based PSM benchmarks allow identification of under-performing outliers who may seek courses or video self-study to improve outcomes. There was significant temporal and geographic variation in PSMs but neither surgeon volume nor surgical approach was associated with PSMs.

TI Professional values and reported behaviours of doctors in the USA and

SO BMJ QUALITY & SAFETY
LA English
DT Article
ID MEDICAL PROFESSIONALISM; MILLENNIUM; PHYSICIANS; CHARTER; CARE; FACE
AB Background: The authors aimed to determine US and UK doctors' professional values and reported behaviours, and the extent to which these vary with the context of care.
Method: 1891 US and 1078 UK doctors completed the survey (64.4% and 40.3% response rate respectively). Multivariate logistic regression was used to compare responses to identical questions in the two surveys.
Results: UK doctors were more likely to have developed practice guidelines (82.8% UK vs 49.6% US, p<0.001) and to have taken part in a formal medical error-reduction programme (70.9% UK vs 55.7% US, p<0.001). US doctors were more likely to agree about the need for periodic recertification (completely agree 23.4% UK vs 53.9% US, p<0.001). Nearly a fifth of doctors had direct experience of an impaired or incompetent colleague in the previous 3 years. Where the doctor had not reported the colleague to relevant authorities, reasons included thinking that someone else was taking care of the problem, believing that nothing would happen as a result, or fear of retribution. UK doctors were more likely than US doctors to agree that significant medical errors should always be disclosed to patients. More US doctors reported that they had not disclosed an error to a patient because they were afraid of being sued.
Discussion: The context of care may influence both how professional values are expressed and the extent to which behaviours are in line with stated values. Doctors have an important responsibility to develop their healthcare systems in ways which will support good professional behaviour.

AB The growth factor receptor-bound protein-7 gene (GRB7) encodes a multi-domain signal transduction molecule. The purpose of this study was to examine the clinical significance of GRB7 protein expression in human breast cancer. Western blotting analysis of protein extracts from 563 annotated frozen breast tumors was performed. Expression status of GRB7 and HER-2 was correlated with clinical covariates and outcomes. Cox proportional hazards were used to identify factors associated with breast cancer-free interval. The median follow-up was 71 months. P values < 0.05 were considered statistically significant (two-sided). A discrepancy between HER-2 and GRB7 protein over-expression was observed. GRB7 protein over-expression was associated with negative estrogen and progesterone receptor status, higher tumor grade, larger primary tumor size, (more) axillary lymph node involvement, higher clinical stage, and shortened breast cancer-free interval. HER-2 protein over-expression was associated only with higher tumor grade. Multi-variate analysis revealed that GRB7 protein over-expression was an independent adverse prognostic factor for breast cancer-free interval (hazard ratio 1.69, 95% confidence interval 1.07-2.67; P = 0.024). The same was true of the subset of patients who did not receive any adjuvant systemic therapy (hazard ratio 1.68, 95% confidence interval 1.16-2.31; P = 0.0055). Using FISH analysis, 32/32 (100%; 95% CI 89-100%) tumors which over-expressed both HER-2 and GRB7 proteins and 1/35 (3%; 95% CI 0-15%) tumors with HER-2 but no GRB7 protein over-expression with Western blotting analysis demonstrated HER-2 gene amplification. GRB7 protein over-expression is an independent adverse prognostic factor in human breast cancer.

AB The remarkable progress in radiation therapy over the last century has been largely due to our ability to more effectively focus and deliver radiation to the tumour target volume. Physics discoveries and technology inventions have been an important driving force behind this progress. However, there is still plenty of room left for future improvements through physics, for example image guidance and four-dimensional motion management and particle therapy, as well as increased efficiency of more compact and cheaper technologies. Bigger challenges lie ahead of physicists in radiation therapy beyond the dose localisation problem, for example in the areas of biological target definition, improved modelling for normal tissues and tumours, advanced multicriteria and robust optimisation, and continuous incorporation of advanced technologies such as molecular imaging. The success of physics in radiation therapy has been based on the continued "fuelling" of the field with new discoveries and inventions from physics research. A key to the success has been the application of the rigorous scientific method. In spite of the importance of physics research for radiation therapy, too few physicists are currently involved in cutting-edge research. The increased emphasis on more "professionalism" in medical physics will tip the situation even more off balance. To prevent this from happening, we argue that medical physics needs more research positions, and more and better academic programmes. Only with more emphasis on medical physics research will the future of radiation therapy and other physics-related medical specialties look as bright as the past, and medical physics will maintain a status as one of the most exciting fields of applied physics.

AB Objectives: A second-order repair kinetics model is developed to predict damage repair rates following low or high linear energy transfer (LET) irradiations and to assess the amount of unrepairable damage produced by such radiations. The model is a further development of an earlier version designed to test if low-LET radiation repair processes could be quantified in terms of second-order kinetics. The newer version allows calculation of both the repair rate of the proportion of DNA damages that repair according to second-order kinetics and the proportion of DNA damages that do not repair.
Methods: The original and present models are intercompared in terms of their goodness-of-fit to a number of data sets obtained from different ion beams. The analysis demonstrates that the present model provides a better fit to the data in all cases studied.
Results: The proportions of unrepairable damage created by radiations of different LET predicted by the new model correspond well with previous studies on the increased effectiveness of high-LET radiations in inducing reproductive cell death. The results show that the original model may underestimate the proportion of unrepaired damage at any given time after its creation as well as failing to predict very slow or unrepairable damage components, which may result from high-LET irradiation.
Conclusion: It is suggested that the second-order model presented here offers a more realistic view of the patterns of repair in cell lines or tissues exposed to high-LET radiation.

AB BACKGROUND: Mitoxantrone plus prednisone and ixabepilone each have modest activity as monotherapy for second-line chemotherapy in patients with docetaxel-refractory castration-resistant prostate cancer. Clinical noncross-resistance was previously observed. Phase 1 testing determined the maximum tolerated dose and dose-limiting toxicities with the combination regimen; a phase 2 study was conducted to evaluate the activity of the combination. METHODS: Patients with metastatic progressive castration-resistant prostate cancer during or after 3 or more cycles of taxane-based chemotherapy enrolled in a phase 2 multicenter study of ixabepilone 35 mg/m(2) and mitoxantrone 12 mg/m(2) administered on Day 1 every 21 days with pegfilgrastim support, along with prednisone 5 mg twice daily. Patients were evaluated for disease response and toxicity. RESULTS: Results are reported for the 56 evaluable patients. Twenty-five (45%; 95% confidence interval [CI], 31%-59%) experienced confirmed >= 50% prostate-specific antigen (PSA) declines, 33 (59%; 95% CI, 45%-72%) experienced confirmed >= 30% PSA declines, and 8 of 36 patients (22%; 95% CI, 10%-39%) with measurable disease experienced objective responses. Median time to PSA or objective progression was 4.4 months (95% CI, 3.5-5.6), and median progression-free survival was also 4.4 months (95% CI, 3.0-6.0). Median overall survival was 12.5 months (95% CI, 10.2-15.9). Thirty-two percent of patients experienced grade 3 of 4 neutropenia, and 11% experienced grade 3 or higher neutropenic infections, including 1 treatment-related death. Grade 2 and 3 neuropathy occurred in 11% and 12.5% of patients, respectively. CONCLUSIONS: These results suggest that the combination of ixabepilone and mitoxantrone is both feasible and active in castration-resistant prostate cancer and requires dosing with pegfilgrastim.

AB BACKGROUND: Past research has linked patient-physician communication with improved emotional, physical, and social health. One component of communication, patient-clinician information engagement (PCIE), predicts improved short-term patient-reported outcomes, such as treatment satisfaction, through perceptions of feeling informed. However, to the authors' knowledge, the relation between PCIE and longer term cancer-related problems has not been examined previously. The authors examined the influence of PCIE on self-reported problems associated with cancer diagnosis and treatment based on a longitudinal survey among a randomly selected sample from the 2005 Pennsylvania Cancer Registry. METHODS: In total, 1293 respondents were surveyed who were diagnosed with colorectal, breast, or prostate cancers during 2006 and 2007. The baseline response rate was 64%, and the retention rate was 65%. The authors predicted an index of cancer-related problems at 1-year follow-up with the baseline cancer-related problem index and PCIE, controlling for demographic and clinical factors using regression analyses. The mean age of participants was 65 years, approximately 50% were women, and 86% were white. RESULTS: Having more cancer-related problems and PCIE at baseline significantly predicted more cancer-related problems at follow-up. In addition, baseline cancer-related problems and PCIE interacted significantly (P=.01): PCIE was associated with more cancer-related problems at follow-up among participants who reported more symptoms rather than fewer symptoms at baseline. CONCLUSIONS: If respondents reported engaging more with their physicians at baseline, then they reported experiencing more cancer-related issues at follow-up; this pattern was stronger among those who reported more baseline problems. The current results indicated that increased discussion of cancer information with physicians may maintain the salience of these problems in cancer survivors' minds over time.

AB Professional APCs, such as dendritic cells, are routinely used in vitro for the generation of cytotoxic T lymphocytes specific for tumor antigens. In addition to dendritic cells, CD40-activated B cells and variant K562 leukemic cells can be readily transfected with nucleic acids for in vitro and in vivo antigen presentation. However, the expression of immunoproteasome components in dendritic cells may preclude display of tumor antigens such as Mart1/MelanA. Here, we use three target epitopes, two derived from tumor antigens [Mart1(26-34) (M26) and Cyp1B1(239-247) (Cyp239)] and one derived from the influenza A viral antigen [FluM1(58-66) (FluM58)], to demonstrate that CD40-activated B cells, like dendritic cells, have a limited capability to process certain tumor antigens. In contrast, the K562 HLA-A*0201 transfectant efficiently processes and presents M26 and Cyp239 as well as the influenza FluM58 epitopes to T cells. These results demonstrate that the choice of target APC for gene transfer of tumor antigens may be limited by the relative efficacy of proteasome components to process certain tumor epitopes. Importantly, K562 can be exploited as an artificial APC, efficient in processing both M26 and Cyp239 epitopes and presumably, by extension, other relevant tumor antigens.

AB Purpose This study was designed to evaluate short (<3 months) and intermediate-term (>3 months) follow-up in patients with metastatic neuroendocrine tumor to the liver who underwent hepatic arterial chemoembolization with drug-eluting beads at a single institution.
Methods Institutional review board approval was obtained for this retrospective review. All patients who were treated with 100-300 or 300-500 mu m drug-eluting LC Beads (Biocompatibles, UK) preloaded with doxorubicin (range, 50-100 mg) for GI neuroendocrine tumor metastatic to the liver from June 2004 to June 2009 were included. CT and MRI were evaluated for progression using Response Evaluation Criteria In Solid Tumors (RE-CIST) or European Association for the Study of the Liver (EASL) criteria. Short-term (<3 months) and intermediateterm (>3 months) imaging response was determined and Kaplan-Meier survival curves were plotted.
Results Thirty-eight drug-eluting bead chemoembolization procedures were performed on 32 hepatic lobes, comprising 21 treatment cycles in 18 patients. All procedures were technically successful with two major complications (biliary injuries). At short-term follow-up (<3 months), 22 of 38 (58%) procedures and 10 of 21 (48%) treatment cycles produced an objective response (OR) with the remainder having stable disease (SD). At intermediate-term follow-up (mean, 445 days; range, 163-1247), 17 of 26 (65%) procedures and 8 of 14 (57%) treatment cycles produced an OR. Probability of progressing was approximately 52% at 1 year with a median time to progression of 419 days.
Conclusions Drug-eluting bead chemoembolization is a reasonable alternative to hepatic arterial embolization and chemoembolization for the treatment of metastatic neuroendocrine tumor to the liver.

AB Background: Angioplasty and stenting are preferred treatments for revascularizing femoral artery lesions up to 100 mm, but surgical bypass is recommended for longer lesions. We assessed long-term patency after percutaneous revascularization of long femoral artery lesions for claudication with intensive out-patient surveillance. Methods: We followed a cohort of 111 consecutive patients receiving angioplasty or stenting in 142 limbs in two institutions. Patients were followed for 2.5 years, and event curves and multivariable survival analysis used to compare outcomes in three groups according to lesion length (< 100 mm, 100-200 mm, and greater than 200 mm). Failed patency was defined as recurrence of symptoms with a decline in ankle brachial index, or stenosis identified by duplex ultrasound, or reintervention. Results: Compared to lesions less than 100 mm, longer lesions had higher failed primary patency (100-200 mm: HR = 2.0, P = 0.16, >200 mm: HR = 2.6, P = 0.03). Failed secondary patency was similar for short and intermediate lesions (< 5% incidence), but trended higher for lesions >200 mm (HR = 4.2, P = 0.06). An initial procedure residual stenosis greater than 20% was the only significant multivariable factor related to poorer long-term patency (HR = 15.8, P = 0.003). Compared to short lesions, the gain in long-term patency with out-patient surveillance and reintervention was higher for longer lesions and significantly so for intermediate lesions (100-200 mm = 23% versus <100 mm = 8%, P = 0.041). Conclusion: Percutaneous treatment of long femoral artery lesions can provide acceptable long-term patency for patients with claudication when out-patient surveillance is used to identify patients who require repeat interventions. Future long-term studies should consider overall patency encompassing more than one percutaneous reintervention. (C) 2011 Wiley-Liss, Inc.

AB Background. Under normal conditions, the expression of CD14, which is the principal receptor for bacterial lipopolysaccharide, is down-regulated in the intestinal mucosa but increases in response to inflammatory stimuli. The aim of the present study was to investigate whether fecal CD14 levels increased in response to infection with diarrheagenic Escherichia coli and whether single nucleotide polymorphisms (SNPs) in the CD14 gene were associated with an increased susceptibility to traveler's diarrhea (TD) in US visitors to Mexico.
Methods. Six SNPs located at the promoter, exon, and untranslated regions of CD14 were typed in a prospective cohort study of 1360 visitors to Mexico at risk for TD. Stools from visitors with TD were studied for enteric pathogens by culture, colony hybridization, and polymerase chain reaction. Fecal soluble CD14 (sCD14) was measured in a subgroup of 203 adults with diarrhea and 66 healthy controls by enzyme-linked immunosorbent assay.
Results. The minor allele frequencies for CD14 SNPs were significantly different among the various racial and ethnic groups studied. Two SNPs in the promoter region of CD14 (-159 C > T; rs2569190 and -4191 C > T; rs5744441) were found to be associated with TD in White visitors. The -159 TT genotype was associated with a higher risk for TD (Relative risk [RR], 1.21; 95% confidence interval [CI], 1.05-1.38; P = .008), whereas individuals with the -4191 TT genotype were protected from infection (RR, 0.82; 95% CI, 0.71-0.92; P = .006). Subjects with TD excreted higher levels of fecal CD14 than did healthy controls (33,480 pg/mL vs 6178 pg/mL; P < .02). Fecal sCD14 levels were higher in stool samples from visitors with TD and the -159 TT genotype than they were in visitors with the CC/CT genotypes (P = .02), and stool samples from subjects with the -4191 CC genotype had higher fecal sCD14 levels than did stool samples from visitors with the CT/TT (P = .005) genotype. In a multivariate analysis with haplotypes constructed with the 6 SNPs studied, subjects with the haplotype containing the -159 C and the -4191 T allele were less likely to acquire TD (P = .015).
Conclusions. Our study suggests that CD14 levels increase in response to bacterial diarrhea and that polymorphisms in the CD14 gene influence susceptibility to TD. Intestinal CD14 plays an important role in the innate immune response to enteric pathogens.

AB The purpose of this study was to examine pediatricians' familiarity with expert committee recommendations on the management of childhood obesity and their use of health information technology for obesity-related care. The authors interviewed 35 pediatricians from 17 primary care practices using an electronic health record; immersion crystallization facilitated analysis of the qualitative data. Nearly all pediatricians were unfamiliar with expert recommendations; however, all participants reported using growth charts and providing nutrition and physical activity counseling. Most participants wanted easy access to educational materials they could print for patients. The majority of participants were in favor of an electronic alert to identify obese patients, remind clinicians of current guidelines, and facilitate ordering, believing it would help standardize care. Concerns included "alert fatigue," distraction, and disruption of workflow. Suggestions for future electronic functions included tailored educational materials and physical activity resources customized by patient address.

AB Objective: To describe and compare characteristics, ventilatory practices, and associated outcomes among mechanically ventilated patients with different types of brain injury and between neurologic and nonneurologic patients.
Design: Secondary analysis of a prospective, observational, and multicenter study on mechanical ventilation.
Setting: Three hundred forty-nine intensive care units from 23 countries.
Patients: We included 552 mechanically ventilated neurologic patients (362 patients with stroke and 190 patients with brain trauma). For comparison we used a control group of 4,030 mixed patients who were ventilated for nonneurologic reasons.
Interventions: None.
Measurements and Main Results: We collected demographics, ventilatory settings, organ failures, and complications arising during ventilation and outcomes. Multivariate logistic regression analysis was performed with intensive care unit mortality as the dependent variable. At admission, a Glasgow Coma Scale score <= 8 was observed in 68% of the stroke, 77% of the brain trauma, and 29% of the nonneurologic patients. Modes of ventilation and use of a lung-protective strategy within the first week of mechanical ventilation were similar between groups. In comparison with nonneurologic patients, patients with neurologic disease developed fewer complications over the course of mechanical ventilation with the exception of a higher rate of ventilator-associated pneumonia in the brain trauma cohort. Neurologic patients showed higher rates of tracheotomy and longer duration of mechanical ventilation. Mortality in the intensive care unit was significantly (p <.001) higher in patients with stroke (45%) than in brain trauma (29%) and nonneurologic disease (30%). Factors associated with mortality were: stroke (in comparison to brain trauma), Glasgow Coma Scale score on day 1, and severity at admission in the intensive care unit.
Conclusions: In our study, one of every five mechanically ventilated patients received this therapy as a result of a neurologic disease. This cohort of patients showed a higher mortality rate than nonneurologic patients despite a lower incidence of extracerebral organ dysfunction. (Crit Care Med 2011; 39: 1482-1492)

AB Purpose: Proliferative vitreoretinopathy (PVR) is believed to result in part from de-differentiation of retinal pigment epithelium (RPE) with cellular migration in the vitreous cavity, membrane formation, and contraction in an aberrant wound-healing strategy. In an in vitro collagen-gel contraction assay, epithelial membrane protein 2 (EMP2) controls contraction through activation of focal adhesion kinase (FAK) in a RPE cell line (ARPE-19). The purpose of this study was to investigate how blocking or altering the level of EMP2 expression changed clinical PVR in an in vivo model.
Methods: Using the ARPE-19 cell line, the levels of EMP2 modulated through stable transfections of an EMP2 overexpressing construct, EMP2 ribozyme, or vector alone. These transfected cell lines were used in a rabbit model of PVR. The severity of PVR was classified by two masked observers. An EMP2 blocking antibody was also used to decrease functional EMP2 in the PVR model. Immunohistochemistry was used to evaluate EMP2 expression in vivo.
Results: The transfectants with lower levels of EMP2 had significantly less PVR severity than the degree of PVR induced by wild-type cells (p = 0.05). Also, the transfectants with a low-level of EMP2 expression showed a strong trend of less PVR severity than the high-levels EMP2 transfectants (p = 0.06). Blocking EMP2 with a specific polyclonal antibody significantly decreased the level of PVR severity (p = 0.02). PVR membranes were found to be positive for EMP2 expression.
Conclusions: These in vivo studies support a direct correlation between EMP2 expression and severity of PVR. These results validate the potential for controlling RPE biology through a change in EMP2 expression, and provide a potential therapeutic target for this disease.

AB Objective:
Nilotinib and dasatinib have not been directly compared in a randomized trial for the treatment of newly diagnosed chronic myeloid leukemia in the chronic phase (CML-CP). The purpose of this study was to indirectly compare rates of major molecular response (MMR), progression-free survival (PFS) and overall survival by month 12 with nilotinib and dasatinib treatment of newly diagnosed CML-CP.
Methods:
Individual patient data from a randomized trial of nilotinib vs. imatinib (ENESTnd) and published summary data from a separate randomized trial of dasatinib vs. imatinib (DASISION) were utilized. A matching-adjusted indirect comparison was conducted by weighting individual patients treated with nilotinib to match baseline characteristics reported for dasatinib-treated patients, including age, gender, ECOG performance status and hematology lab values. After matching, efficacy outcomes were compared for patients treated with nilotinib 300 mg twice daily vs. dasatinib 100 mg once daily. Patients randomized to imatinib 400 mg once daily in each trial were used to assess the adequacy of the matching.
Results:
Before matching, patients randomized to nilotinib in ENESTnd (n = 273) were older, with a lower median platelet count and more favorable performance status compared to patients randomized to dasatinib in DASISION (n = 259). After matching, all baseline characteristics were balanced across treatment groups. Matched patients treated with nilotinib vs. dasatinib experienced significantly higher rates of MMR (56.8 vs. 45.9%, p = 0.014) and overall survival (99.5 vs. 97.3%, p = 0.046) and numerically higher rates of PFS (98.8 vs. 96.5%). Matched imatinib arms showed no statistically significant or clinically meaningful differences in these outcomes.
Limitations:
Baseline measures unavailable in one or both trials could not be matched. Adverse event rates were not formally compared across trials due to differences in reporting.
Conclusion:
Nilotinib was associated with significantly higher rates of MMR and overall survival compared with dasatinib by month 12 in the treatment of newly diagnosed CML-CP.

AB KRAS mutations exhibit significant predictive and prognostic value in cancer. Efficient, sensitive, and accurate molecular approaches are required to evaluate KRAS mutation status, even when mutant alleles are restricted to a small portion of a clinical sample, which otherwise contains wild-type alleles. We describe a highly sensitive method to detect KRAS mutations by high-resolution melting (HRM) analysis after mutation enrichment by fast-COLDpolymerase chain reaction (PCR). Using 10 ng of starting DNA and after fast-COLD-PCR of a 76-bp region containing KRAS codons 12 and 13; the amplicons undergo a nested conventional PCR reaction followed by HRM analysis. Samples exhibiting aberrant melting profiles are sequenced to identify mutation type and position. Serial dilution experiments indicate a sensitivity of approximately 0.3% mutant-to-wild type for HRM-based mutation detection and the ability to directly sequence mutation-containing samples. A number of lung adenocarcinoma specimens earlier characterized were screened. Fast-COLD-PCR-HRM analysis correctly identified KRAS mutations and also showed a previously undetected, low-level missense GGT > TTT complex mutation. On account of the short target regions and low requirement of starting DNA, this rapid, cost-effective, and sensitive fast-COLD-PCR-HRM approach is expected to find broad application for detecting low-abundance KRAS mutations in a wide range of clinical specimens.

AB Background Cigarette use is associated with esophageal adenocarcinoma, and cross-sectional studies suggest an association between smoking and Barrett's esophagus.
Aims We sought to examine prospectively the effect of smoking on the risk for Barrett's esophagus.
Methods This was a prospective cohort study among 20,863 women within the Nurses' Health Study who underwent upper gastrointestinal endoscopy for any reason between 1980 and 2006. We assessed the association between smoking and pathologically-confirmed Barrett's esophagus (n = 377). Self-reported data on smoking and potential confounding variables were collected from biennial questionnaires.
Results Compared with women who never smoked, former smokers of 1-24 cigarettes/day had a multivariate odds ratio for Barrett's esophagus of 1.25 (95% CI 0.99-1.59), former smokers of a parts per thousand yen25 cigarettes/day had a multivariate odds ratio of 1.52 (95% CI 1.04-2.22), current smokers of 1-24 cigarettes/day had a multivariate odds ratio of 0.89 (95% CI 0.54-1.45), and current smokers of a parts per thousand yen25 cigarettes/day had a multivariate odds ratio of 0.92 (95% CI 0.34-2.54). The risk for Barrett's esophagus increased significantly with increasing pack-years smoked among former (P = 0.008) but not current smokers (P = 0.99), especially when considering exposure a parts per thousand yen25 years before index endoscopy. Results were similar among women reporting regular heartburn/acid-reflux one or more times a week, and were not accounted for by changes in weight.
Conclusions Heavy, remote smoking is associated with an increased risk for Barrett's esophagus. This finding suggests a long latency period between exposure and development of the disease, even after discontinuation of smoking.

AB Background Proton pump inhibitors (PPIs), widely prescribed to patients with upper gastrointestinal symptoms, alter intragastric pH, and may affect upper gastrointestinal transit and motility parameters in addition to affecting the ability to determine Wireless Motility Capsule (WMC) gastric emptying time.
Aim To assess PPI effect on motility parameters of the upper gastrointestinal tract and to determine if PPIs confound ability of WMC to measure gastric emptying time.
Methods Twenty healthy subjects were treated with esomeprazole 40 mg bid for 1 week. Another 50 healthy subjects underwent evaluation in absence of PPIs. All subjects underwent WMC test after meal ingestion. After a rapid, sustained luminal pH rise a parts per thousand yen 0.5 pH units, marking potential gastric emptying time of WMC, an abdominal X-ray (KUB) was taken for gastric emptying time confirmation. Mean pH, pressure and transit time were compared between PPI-treated and untreated groups.
Results There was no difference in gastric emptying time, small bowel transit time (SBTT), or pressure profiles between the groups. The pH in all cases rose a parts per thousand yen 0.5 pH units. Distal small bowel pH was significantly lower in subjects on PPIs. Gastric emptying time was identified in all subjects treated with PPIs. Pressure and slope criteria were developed to confirm the time of emptying.
Conclusion PPI therapy does not have a significant impact on upper gastrointestinal transit and motility but it does decrease distal small bowel pH. The medication reduced the magnitude of pH change at gastric emptying time but using additional criteria based on slope and contraction frequency, WMC was able to measure gastric emptying time in all patients treated with PPIs.

AB After oophorectomy, mRen2.Lewis rats exhibit diastolic dysfunction associated with elevated superoxide, increased cardiac neuronal nitric oxide synthase (nNOS) expression, and diminished myocardial tetrahydrobiopterin (BH4) content, effects that are attenuated with selective nNOS inhibition. BH4 is an essential cofactor of nNOS catalytic activity leading to nitric oxide production. Therefore, we assessed the effect of 4wk BH4 supplementation on diastolic function and left ventricular (LV) remodeling in oophorectomized mRen2.Lewis rats compared with sham-operated controls. Female mRen2.Lewis rats underwent either bilateral ovariectomy (OVX) (n = 19) or sham operation (n = 13) at 4wk of age. Beginning at 11 wk of age, OVX rats were randomized to receive either BH4 (10 mg/kg.d) or saline, whereas the sham rats received saline via sc mini-pumps. Loss of ovarian hormones reduced cardiac BH4 when compared with control hearts; this was associated with impaired myocardial relaxation, augmented filling pressures, increased collagen deposition, and thickened LV walls. Additionally, superoxide production increased and nitric oxide decreased in hearts from OVX compared with sham rats. Chronic BH4 supplementation after OVX improved diastolic function and attenuated LV remodeling while restoring myocardial nitric oxide release and preventing reactive oxygen species generation. These data indicate that BH4 supplementation protects against the adverse effects of ovarian hormonal loss on diastolic function and cardiac structure in mRen2.Lewis rats by restoring myocardial NO release and mitigating myocardial O-2(-) generation. Whether BH4 supplementation is a therapeutic option for the management of diastolic dysfunction in postmenopausal women will require direct testing in humans. (Endocrinology 152: 2428-2436, 2011)

AB Pyridoxine, or vitamin B6, is commonly used to treat acquired idiopathic sideroblastic anaemia (AISA, including refractory anaemia with ring sideroblasts), but the efficacy of this therapy in an unselected AISA population (i.e. patients without confirmed ALAS2 or other pyridoxine-responsive germline mutations) has not been established. We reviewed clinical data from 231 patients with AISA and found that 42% of 203 evaluable patients had been treated with pyridoxine. Only 6.8% of pyridoxine-treated patients experienced a haemoglobin improvement (>= 1.5 g/dL) meeting 2006 International Working Group for Myelodysplastic Syndromes standardised response criteria. As some patients received combination therapy with erythropoietin or other agents, improvement could be attributed to pyridoxine monotherapy in only one patient (1.4%). Smaller, less meaningful increments in haemoglobin levels of 0.5 g/dL were observed in 13.5% of patients. Response to therapy did not correlate with International Prognostic Scoring System (IPSS) risk group or multilineage vs unilineage dysplasia. New symptomatic peripheral neuropathy was noted in 2.3% of patients treated with pyridoxine. In this large series of unselected patients with sideroblastic anaemia, pyridoxine therapy was ineffective and was associated with a risk of adverse effects. Pyridoxine therapy should be reserved for patients with known or suspected pyridoxine-responsive mutations.

AB Objective
To test the utility of a two-dimensional model of organizational climate for explaining variation in diabetes care between primary care clinics.
Data Sources/Study Setting
Secondary data were obtained from 223 primary care clinics in the Department of Veterans Affairs health care system.
Study Design
Organizational climate was defined using the dimensions of task and relational climate. The association between primary care organizational climate and diabetes processes and intermediate outcomes were estimated for 4,539 patients in a cross-sectional study.
Data Collection/Extraction Methods
All data were collected from administrative datasets. The climate data were drawn from the 2007 VA All Employee Survey, and the outcomes data were collected as part of the VA External Peer Review Program. Climate data were aggregated to the facility level of analysis and merged with patient-level data.
Principal Findings
Relational climate was related to an increased likelihood of diabetes care process adherence, with significant but small effects for adherence to intermediate outcomes. Task climate was generally not shown to be related to adherence.
Conclusions
The role of relational climate in predicting the quality of chronic care was supported. Future research should examine the mediators and moderators of relational climate and further investigate task climate.

ID SHORT-TERM MORTALITY; RECTAL-CANCER; COLON-CANCER; QUALITY; CARE;

AB Objective
To profile hospitals by survival rates of colorectal cancer patients in multiple periods after initial treatment.
Data Sources
California Cancer Registry data from 50,544 patients receiving primary surgery with curative intent for stage I-III colorectal cancer in 1994-1998, supplemented with hospital discharge abstracts.
Study Design
We estimated a single Bayesian hierarchical model to quantify associations of survival to 30 days, 30 days to 1 year, and 1-5 years by hospital, adjusted for patient age, sex, race, stage, tumor site, and comorbidities. We compared two profiling methods for 30-day survival and four longer-term profiling methods by the fractions of hospitals with demonstrably superior survival profiles and of hospital pairs whose relative standings could be established confidently.
Principal Findings
Interperiod correlation coefficients of the random effects are (95 percent credible interval 0.27, 0.85), (0.20, 0.76), and (0.19, 0.82). The three-period model ranks 5.4 percent of pairwise comparisons by 30-day survival with at least 95 percent confidence, versus 3.3 percent of pairs using a single-period model, and 15-20 percent by weighted multiperiod methods.
Conclusions
The quality of care for colorectal cancer provided by a hospital system is somewhat consistent across the immediate postoperative and long-term follow-up periods. Combining mortality profiles across longer periods may improve the statistical reliability of outcome comparisons.

AB Objective
To link data from a central cancer registry with Medicaid enrollment and claims files in order to assess cancer care in an economically disadvantaged population.
Data Sources
Over 500,000 cancer patients diagnosed between 2002 and 2006 reported to the New York State Cancer Registry were linked with New York State Medicaid enrollment and claims records.
Study Design
A probabilistic linkage was performed between the two data sources. The resulting Medicaid and non-Medicaid populations were compared in terms of demographics and stage at diagnosis.
Data Collection Methods
Existing databases were used.
Principal Findings
One-quarter of cancer patients were enrolled in Medicaid at or near the time of cancer diagnosis. The Medicaid cohort was younger, more likely to be an ethnic minority, foreign born, never married, live in either an inner-city or remote rural area, and have a higher stage at diagnosis.
Conclusions
The linked dataset will permit detailed analysis of cancer treatment and cancer treatment disparities among historically understudied groups. The linkage has also resulted in improvements in Cancer Registry quality through the identification of errors and missing values. The linkage did present technical challenges in the form of immense file sizes not easily adaptable to desktop computers.

AB Data regarding ethnic differences in wave reflections, which markedly affect the central pressure profile, are very limited. Furthermore, because age, heart rate, and body height are strong determinants of augmentation index, relating single measurements to normative data (in which augmentation index values correspond with average population values of its determinants) is challenging. We studied subject-level data from 10 550 adults enrolled in large population-based studies. In a healthy reference sample (n = 3497), we assessed ethnic differences in augmentation index (ratio of second/first systolic peaks) and generated equations for adjusted z scores, allowing for a standardized comparison between individual augmentation index measurements and the normative population mean from subjects of the same age, sex, ethnic population, body height, and heart rate. After adjustment for age, body height, heart rate, and mean arterial pressure, African blacks (women: 154%; men: 138%) and Andean Hispanics (women: 152%; men: 133%) demonstrated higher central (aortic) augmentation index values than British whites (women: 140%; men: 128%), whereas American Indians (women: 133%; men: 122%) demonstrated lower augmentation index (all P < 0.0001), without significant differences between Chinese and British whites. Similar results were found for radial augmentation index. Nonlinear ethnic/sex-specific equations for z scores were successfully generated to adjust individual augmentation index values for age, body height, and heart rate. Marked ethnic differences in augmentation index exist, which may contribute to ethnic differences in hypertensive organ damage. Our study provides normative data that can be used to complement the interpretation of individual hemodynamic assessments among men and women of various ethnic populations, after removing the effect of various physiological determinants.

ID NEURAL SPIKING
AB We propose a point process model of spiking activity from auditory neurons. The model takes account of the neuron's intrinsic dynamics as well as the spectrotemporal properties of an input stimulus. A discrete Volterra expansion is used to derive the form of the conditional intensity function. The Volterra expansion models the neuron's baseline spike rate, its intrinsic dynamics-spiking history-and the stimulus effect which in this case is the analog of the spectrotemporal receptive field (STRF). We performed the model fitting efficiently in a generalized linear model framework using ridge regression to address properly this ill-posed maximum likelihood estimation problem. The model provides an excellent fit to spiking activity from 55 auditory nerve neurons. The STRF-like representation estimated jointly with the neuron's intrinsic dynamics may offer more accurate characterizations of neural activity in the auditory system than current ones based solely on the STRF.

AB Chronic infection with intestinal helminth parasites is a major public health problem, particularly in the developing world, and can have significant effects on host physiology and the immune response to other enteric infections and antigens. The mechanisms underlying these effects are not well understood. In the current study, we investigated the impact of infection with the murine nematode parasite Heligmosomoides polygyrus, which resides in the duodenum, on epithelial barrier function in the colon. We found that H. polygyrus infection produced a significant increase in colonic epithelial permeability, as evidenced by detection of elevated serum levels of the tracer horseradish peroxidase following rectal administration. This loss of normal barrier function was associated with clear ultrastructural changes in the tight junctions of colonic epithelial cells and an alteration in the expression and distribution of the junctional protein E-cadherin. These parasite-induced abnormalities were not observed in SCID mice but did occur in SCID mice that were adoptively transferred with wild-type T cells, indicating a requirement for adaptive immunity. Furthermore, the helminth-induced increase in gut permeability was not seen in STAT6 knockout (KO) mice. Taken together, the results demonstrate that one of the mechanisms by which helminths exert their effects involves the lymphocyte-and STAT6-dependent breakdown of the intestinal epithelial barrier. This increase in epithelial permeability may facilitate the movement of lumenal contents across the mucosa, thus helping to explain how helminth infection can alter the immune response to enteric antigens.

AB Purpose: To evaluate the association between the interval from breast-conserving surgery (BCS) to radiotherapy (RT) and the clinical outcome among patients treated with adjuvant endocrine therapy.
Patients and Methods: Patient information was obtained from three International Breast Cancer Study Group trials. The analysis was restricted to 964 patients treated with BCS and adjuvant endocrine therapy. The patients were divided into two groups according to the median number of days between BCS and RT and into four groups according to the quartile of time between BCS and RT. The endpoints were the interval to local recurrence, disease-free survival, and overall survival. Proportional hazards regression analysis was used to perform comparisons after adjustment for baseline factors.
Results: The median interval between BCS and RT was 77 days. RT timing was significantly associated with age, menopausal status, and estrogen receptor status. After adjustment for these factors, no significant effect of a RT delay weeks was found. The adjusted hazard ratio for RT within 77 days vs. after 77 days was 0.94(95% confidence interval [CI], 0.47-1.87) for the interval to local recurrence, 1.05 (95% CI, 0.82-1.34) for disease-free survival, and 1.07 (95% CI, 0.77-1.49) for overall survival. For the interval to local recurrence the adjusted hazard ratio for <= 48, 49-77, and 78-112 days was 0.90(95% CI, 0.34-2.37), 0.86 (95% CI, 0.33-2.25), and 0.89 (95% CI, 0.33-2.41), respectively, relative to >= 113 days.
Conclusion: A RT delay of <= 20 weeks was significantly associated with baseline factors such as age, menopausal status, and estrogen-receptor status. After adjustment for these factors, the timing of RT was not significantly associated with the interval to local recurrence, disease-free survival, or overall survival. (C) 2011 Elsevier Inc.

AB Purpose: We compared four-dimensional (4D) layer-stacking and conventional carbon ion beam distribution in the treatment of lung cancer between ungated and gated respiratory strategies using 4DCT data sets.
Methods and Materials: Twenty lung patients underwent 4DCT imaging under free-breathing conditions. Using planning target volumes (PTVs) at respective respiratory phases, two types of compensating bolus were designed, a full single respiratory cycle for the ungated strategy and an approximately 30% duty cycle for the exhalationgated strategy. Beams were delivered to the PTVs for the ungated and gated strategies, PTV(ungated) and PTV(gated), respectively, which were calculated by combining the respective PTV(Tn)s by layer-stacking and conventional irradiation. Carbon ion beam dose distribution was calculated as a function of respiratory phase by applying a compensating bolus to 4DCT. Accumulated dose distributions were calculated by applying deformable registration.
Results: With the ungated strategy, accumulated dose distributions were satisfactorily provided to the PTV, with 1195 values for layer-stacking and conventional irradiation of 94.0% and 96.2%, respectively. V20 for the lung and Dmax for the spinal cord were lower with layer-stacking than with conventional irradiation, whereas Dmax for the skin (14.1 GyE) was significantly lower (21.9 GyE). In addition, dose conformation to the GTV/PTV with layer-stacking irradiation was better with the gated than with the ungated strategy.
Conclusions: Gated layer-stacking irradiation allows the delivery of a carbon ion beam to a moving target without significant degradation of dose conformity or the development of hot spots. (C) 2011 Elsevier Inc.

AB With the use of combination antiretroviral therapy, the proportion of HIV-infected patients over age 50 has greatly increased. The rate of progression of untreated HIV disease, response to therapy and complicating effects of co-morbidities differ in older versus younger patients. Compared with younger individuals, older untreated HIV patients demonstrate faster rates of CD4+ cell loss and more rapid progression to AIDS and death. With treatment, older patients have a better virological response, but a less robust immunological response. The treatment of older HIV-infected patients is further complicated by pre-existing co-morbid conditions including cardiovascular, hepatic and metabolic complications that may be exacerbated by the effects of HIV infection per se, modest immunodeficiency (i.e. at CD4+ counts >350 cells/mm(3)), and the metabolic and other adverse effects of combination antiretroviral therapy. Based on these considerations guidelines for the treatment of HIV-infected patients state that increased age is a consideration in initiating antiretroviral therapy in persons with >350-500 CD4+ cells/mm(3).

AB The CD8 gene is silent in CD4(-)CD8(-) double-negative thymocytes, expressed in CD4(+)CD8(+) double-positive cells, and silenced in cells committing to the CD4(+) single-positive (SP) lineage, remaining active in the CD8(+) SP lineage. In this study, we show that the chromatin of the CD8 locus is remodeled in C57BL/6 and B6/J Rag1(-/-) MOM double-negative thymocytes as indicated by DNaseI hypersensitivity and widespread bivalent chromatin marks. Pre-TCR signaling coincides with chromatin bivalency resolution into monovalent activating modifications in double-positive and CD8 SP cells. Shortly after commitment to CD4 SP cell lineage, monovalent repressive characteristics and chromatin inaccessibility are established. Differential binding of Ikaros, NuRD, and heterochromatin protein 1 alpha on the locus during these processes may participate in the complex regulation of CD8.

AB We have developed a cancer vaccine in which autologous tumor is fused with dendritic cells (DCs) resulting in the presentation of tumor antigens in the context of DC-mediated costimulation. In clinical trials, immunologic responses have been observed, however responses may be muted by inhibitory pathways. The PD1/PDL1 pathway is an important element contributing to tumor-mediated immune suppression. In this study, we demonstrate that myeloma cells and DC/tumor fusions strongly express PD-L1. Compared with a control population of normal volunteers, increased PD-1 expression was observed on T cells isolated from patients with myeloma. It is interesting to note that after autologous transplantation, T-cell expression of PD-1 returned to levels seen in normal controls. We examined the effect of PD-1 blockade on T-cell response to DC/tumor fusions ex vivo. Presence of CT-011, an anti-PD1 antibody, promoted the vaccine-induced T-cell polarization towards an activated phenotype expressing Th1 compared with Th2 cytokines. A concomitant decrease in regulatory T cells and enhanced killing in a cytotoxicity assay was observed. In summary, we demonstrate that PD-1 expression is increased in T cells of patients with active myeloma, and that CT-011 enhances activated T-cell responses after DC/tumor fusion stimulation.

AB Background. Tuberculosis (TB) often occurs among household contacts of people with active TB. It is unclear whether clustering of cases represents household transmission or shared household risk factors for TB.
Methods. We used cross-sectional data from 764 households in Lima, Peru, to estimate the relative contributions of household and community transmission, the average time between cases, and the immunity afforded by a previous TB infection.
Results. The distribution of cases per household suggests that almost 7 of 10 nonindex household cases were infected in the community rather than in the household. The average interval between household cases was 3.5 years. We observed a saturation effect in the number of cases per household and estimated that protective immunity conferred up to 35% reduction in the risk of disease.
Conclusions. Cross-sectional household data can elucidate the natural history and transmission dynamics of TB. In this high-incidence setting, we found that the majority of cases were attributable to community transmission and that household contacts of case patients derive some immunity from household exposures. Screening of household contacts may be an effective method of detecting new TB cases if carried out over several years.

AB We investigated the association of polymorphisms in CCR5, the major human immunodeficiency virus (HIV)-1 coreceptor, and copy number of its potent ligand CCL3L1 with tuberculosis in 298 individuals from Colombia. The CCR5-HHD haplotype, a known genetic determinant of increased susceptibility to HIV-AIDS, and a high copy number of CCL3L1, a known genetic determinant of enhanced CCL3/CCL3L1 chemokine expression, each associated with presence of tuberculosis. Furthermore, CCR5-HHD was associated with higher CCR5 gene and surface expression. These results substantiate the strong link between the pro-inflammatory effects of CCR5 and its ligands with active tuberculosis and suggest that chemokine-chemokine receptor genetic determinants may influence tuberculosis in addition to HIV/AIDS.

AB Targeting angiogenesis in glioblastoma (GBM) may improve patient outcome by normalizing tumor vasculature and improving delivery of chemotherapeutics and oxygen. Consequently, concomitant administration of small molecule inhibitors of the VEGF pathway will likely have a positive impact on chemoradiation treatment outcome. We conducted a Phase I study of vatalanib, a small molecule inhibitor of VEGFR, PDGFR, and c-kit in patients with newly diagnosed GBM receiving radiation, temozolomide, and an enzyme-inducing anti-epileptic drug in order to determine the MTD of vatalanib in this patient population. We incorporated circulating biomarker and SNP analyses and pharmacokinetic studies. Nineteen patients were enrolled and the MTD was not reached at the time of study termination. Vatalanib was well tolerated with only 2 DLTs (thrombocytopenia and elevated transaminases). Other grade 3/4 toxicities included leukopenia, lymphopenia, neutropenia, and hand-foot syndrome. There were no wound-healing complications. Of the 13 patients evaluable for a radiographic response, 2 had a partial response and 9 had stable disease. Vatalanib significantly increased PlGF and sVEGFR1 in plasma circulation and decreased sVEGFR2 and sTie2. Plasma collagen IV increased significantly by day 50 of treatment. Vatalanib was well tolerated and this study demonstrates the safety of oral small molecule inhibitors in newly diagnosed GBM patients. Blood biomarkers may be useful as pharmacodynamic markers of response to anti-angiogenic therapies.

AB In the context of bevacizumab therapy for the treatment of progressive malignant gliomas, it is currently unclear how different magnetic resonance imaging (MRI) sequences correlate with each other over time. The objective of this study was to determine if a reliable and predictable relationship over time exists between post-gadolinium based contrast agent T1-weighted (T1 + GBCA), T2-weighted, and FLAIR MRI in patients with progressive glioblastoma multiforme (GBM) receiving bevacizumab and chemotherapy. The MRI lesion volumes of 10 patients with progressive GBM that received bevacizumab plus chemotherapy were manually calculated by two independent reviewers. T2 and FLAIR volumes were analyzed by analysis of covariance (ANCOVA) as a function of T1 + GBCA lesion enhancement volume, reviewer, and time interval between MRI acquisitions. Pearson product moment correlation (r) was used to compare pre and post treatment volumes for the group of 10 patients and for each individual patient over their treatment course. ANCOVA demonstrated a significant association between T1 + GBCA and T2-weighted volumes (P = 0.0006) and between T1 + GBCA and FLAIR volumes (P < 0.0001). These associations remained constant over time. The correlation between T1 + GBCA and both T2-weighted and FLAIR volumes improved after bevacizumab treatment. Individual correlations between T1 + GBCA and FLAIR were strong (r a parts per thousand yen 0.63) with one exception, while correlations between T1 + GBCA and T2 were more variable (r = 0.18-0.99). These findings suggest that FLAIR MRI should be evaluated in addition to T1 + GBCA MRI when evaluating GBM responses.

AB The field of retinal prosthetic research, now more than 20 years old, has producedmany high-quality technical options that have the potential to restore vision to patients with acquired disease of the outer retina. Five companies have performed Phase I clinical trials demonstrating that blind patients can reliably report basic elements of visual percepts induced by electrical stimulation. However, at present patients and observers generally do not consider the results to be useful enough in the performance of tasks of daily living to justify the risks of surgery and chronic implantation or the costs. Having developed a wireless device implanted in the subretinal space, the Boston Retinal Implant Project has focused its efforts on developing scalable technologies to create a hermetic device that can deliver individually controlled pulses of electrical stimulation to each of hundreds of electrodes. An advanced device with such attributes will be needed to justify the risks of implantation. An assessment of long-term biocompatibility for all devices remains to be done.

ID HAND
AB Children with brachial plexus birth injuries often require tendon transfer to restore active wrist extension and maximize hand function. The purpose of this study is to assess the clinical results in children with brachial plexus birth injuries after tendon transfer to reconstruct active wrist extension. Over a 10-year period, 21 children (11 male, 10 female) underwent tendon transfer to reconstruct active wrist extension by a single surgeon. Eight patients had C5/C6/C7 injury and 13 patients had global palsy (C5-T1). The average age at surgery was 5.5 years (range, 3 to 8 y). Restoration of wrist extension was measured according to the functional scale of Duclos and Gilbert. The mean duration of follow-up was 36 months (minimum follow-up of 1 y). At latest follow-up, 14 (66%) children (C5/C6/C7, n = 8; global, n = 6) demonstrated active wrist extension >= 30 degrees. Within the global injury subcohort, 3 patients demonstrated static extension of the wrist. Four failures occurred in the global palsy group. Children with absent active wrist extension after a brachial plexus birth injury can benefit from a tendon transfer. The more severe global palsy cases have a worse outcome.

AB Background. We have previously observed that donor bone marrow hematopoietic stem cells successfully induce transient mixed chimerism and renal allograft tolerance following non-myeloablative conditioning of the recipient. Stem cells isolated from the peripheral blood (PBSC) may provide similar benefits. We sought to determine the most effective method of mobilizing PBSC for this approach and the effects of differing conditioning regimens on their engraftment.
Methods. A standard dose (10 mu g/kg) or high dose (100 mu g/kg) of granulocyte colony-stimulating factor (GCSF) with or without stem cell factor (SCF) was administered to the donor, and PBSC were collected by leukapheresis. Cynomolgus monkey recipients underwent a nonmyeloablative conditioning regimen (total body irradiation, thymic irradiation, and ATG) with splenectomy (splenectomy group) or a short course of anti-CD154 antibody (aCD154) (aCD154 group). Recipients then received combined kidney and PBSC transplantation and a 1-mo post-transplant course of cyclosporine.
Results. Treatments with either two cytokines (GCSF + SCF) or high dose GCSF provided significantly more hematopoietic progenitor cells than standard dose GCSF alone. Recipients in the aCD154 group developed significantly higher myeloid and lymphoid chimerism (P < 0.0001 and P = 0.0002, respectively) than those in the splenectomy group. Longer term renal allograft survival without immunosuppression was also observed in the aCD154 group, while two of three recipients in the splenectomy group rejected their allografts soon after discontinuation of immunosuppression.
Conclusions. Protocols including administration of two cytokines (GCSF + SCF) or high dose GCSF alone significantly mobilized more PBSC than standard dose GCSF alone. The recipients of PBSC consistently developed excellent chimerism and survived long-term without immunosuppression, when treated with CD154 blockade. (C) 2011 Elsevier Inc. All rights reserved.

AB Objective: Pulmonary function frequently deteriorates after cardiopulmonary bypass (CPB). Chronic obstructive pulmonary disease (COPD) increases risk of respiratory complications after CPB. Cysteinyl leukotrienes are important mediators of respiratory dysfunction. Their role during cardiac surgery and its lung complications is incompletely understood. We studied whether production of cysteinyl leukotrienes changes during and after cardiac surgery with CPB and differs between patients with and without COPD.
Methods: Patients with (n = 9) and without (n = 10) moderate-to-severe COPD undergoing cardiac surgery with CPB were prospectively included. Plasma and urinary cysteinyl leukotriene and leukotriene B(4) concentrations were measured by enzyme-linked immunosorbent assay after anesthesia induction, at end of CPB, after CPB, and 2 hours after intensive care unit admission. Gas exchange and respiratory mechanics were also assessed.
Results: Patients with COPD had larger airway resistances after CPB and chest closure (P <. 001), lower ratio of arterial Po(2) to inspired oxygen fraction at intensive care unit admission (215 +/- 37 vs 328 +/- 30 mm Hg, P <. 05), and longer postoperative mechanical ventilation (13.7 +/- 5.8 vs 6.8 +/- 3.4 hours, P <. 01). Urinary cysteinyl leukotriene concentrations increased with time in both groups (P <. 01), but more in patients with than without COPD (P <. 05). Plasma cysteinyl leukotriene concentrations increased significantly between baseline and intensive care unit admission in patients with but not without COPD (P <. 01). Concentrations of leukotriene B(4) in plasma and urine did not increase significantly with time and were not different between groups.
Conclusions: Release of cysteinyl leukotrienes increases during cardiac surgery with CPB and is larger in patients with than without COPD. This may be related to higher lung and airway production of cysteinyl leukotrienes and neutrophil activation in patients with COPD. (J Thorac Cardiovasc Surg 2011;141:1496-502)

AB Introduction: Although most smokers diagnosed with lung cancer report that they want to quit smoking, many do not succeed. Smokers who quit when lung cancer is diagnosed have improved treatment efficacy, quality of life, and survival. Effective smoking cessation interventions targeted to thoracic oncology patients are needed.
Methods: This pilot study examined the feasibility and potential efficacy of a 12-week program that combined smoking cessation counseling with varenicline. Seven-day point prevalence tobacco abstinence rates at the end of treatment were compared with a usual care control group. From January 2008 to August 2009, patients with a diagnosed or suspected thoracic malignancy were recruited at their initial visit to a thoracic surgeon or thoracic oncologist at Massachusetts General Hospital.
Results: Of 1130 patients screened, 187 (17%) were current smokers, and an additional 66 (6%) reported quitting within the past 6 months. One hundred sixteen (67%) of smokers were eligible, and 49 (42%) of eligible smokers enrolled (control group n = 17, intervention group n = 32). Intervention participants completed a median of nine counseling sessions; 50% of intervention participants completed the full varenicline course. At 12-week follow-up, biochemically validated 7-day point prevalence tobacco abstinence rates were 34.4% in the intervention group versus 14.3% in the control group (odds ratio = 3.14, 95% confidence interval = 0.59-16.62, p = 0.18).
Conclusion: Our findings support the feasibility and acceptability of this program. At the end of treatment, quit rates were higher in the control group. Further testing is indicated to establish the efficacy of this treatment package in a randomized clinical trial.

AB Epidemiological studies have shown the protective effect of KIR3DL1/HLA-Bw4 genotypes in human immunodeficiency virus type 1 (HIV-1) infection; however, the functional correlates for the protective effect remain unknown. We investigated whether human leukocyte antigen (HLA)-Bw4-presented HIV-1 peptides could affect the interaction between the inhibitory natural killer (NK) cell receptor KIR3DL1 and its ligand HLA-Bw4. Distinct HIV-1 epitopes differentially modulated the binding of KIR3DL1 to HLA-Bw4. Furthermore, cytotoxic T lymphocyte (CTL) escape mutations within the immunodominant HLA-B57 (Bw4)-restricted Gag epitope TSTLQEQIGW abrogated KIR3DL1 binding to HLA-B57, suggesting that sensing of CTL escape variants by NK cells can contribute to the protective effect of the KIR3DL1/HLA-Bw4 compound genotype.

AB Objective: Studies provide conflicting results about the impact of comorbid conditions on the quality of chronic illness care. We assessed the effect of comorbidity type (concordant, discordant, or both) on the receipt of guideline-recommended care among patients with diabetes.
Research Design: Patients were assigned to 1 of 4 condition groups: diabetes-concordant (hypertension, ischemic heart disease, hyperlipidemia), and/or diabetes-discordant (arthritis, depression, chronic obstructive pulmonary disease) conditions, or neither. We evaluated hemoglobin A1c, blood pressure, and low-density lipoprotein cholesterol readings at index and measured overall good quality of diabetes care, including a 6-month follow-up interval. We assessed the effect of condition group on overall good quality of care with logistic regression and generalized ordered logistic regression.
Results: We assigned 35,872 patients to the diabetes comorbid condition groups, ranging from 2.0% in the discordant-only group to 58.0% in the concordant-only group. Patients with both types of conditions were more likely than those with no comorbidities to receive overall good quality for glycemic [odds ratio (OR), 2.13; 95% confidence interval (CI), 1.86-2.41], blood pressure (OR, 1.62; 95% CI, 1.40-1.84), and low-density lipoprotein cholesterol (OR, 3.57; 95% CI, 3.08-4.05) control within 6 months of an index visit. They were also more likely to receive overall good quality for all 3 quality measures combined (OR, 2.17; 95% CI, 1.96-2.39).
Conclusions: Patients with the greatest clinical complexity were more likely than less complex patients to receive high quality diabetes care, suggesting that increased complexity does not necessarily predispose chronically ill patients to receiving poorer care. However, caution should be used in treating certain patient groups, such as the elderly, for whom adherence to multiple condition-specific guidelines may lack benefit or cause harm.

AB Sharing lessons from high-performing hospitals facilitates quality improvement. High-performing hospitals have usually been identified using a small number of performance measures. The objective was to analyze how well 1,006 hospitals performed across a broader range of measures. Five measures were developed from publicly available data: adherence to processes of care, 30-day readmission rates, in-hospital mortality, efficiency, and patient satisfaction. For a subset of hospitals, the authors included two survey-based assessments of patient care quality, one by chief quality officers and one by frontline clinicians. In general, there was little correlation among the publicly available measures (r <= .10), though there was notable correlation between objective measures and survey-based measures (r = .23). Hospitals that performed well on a composite measure calculated from the publicly available measures were often not in the top quintile on most individual measures. This highlights the challenge in identifying high-performing hospitals to learn organizational-level best practices.

Purpose: The purpose of this study was to examine the influence of a preferred-versus a prescribed-intensity exercise session on pain in women with fibromyalgia (FM). Methods: Twenty-one women with FM (mean age = 44 yr) completed two randomly assigned exercise sessions consisting of 20 min of cycle ergometry at a self-selected intensity and a prescribed intensity. Experimental pain perception was assessed before and after aerobic exercise. During exercise, HR, watts, RPE, and muscle pain were assessed every 5 min. Clinical pain was assessed with the Short-Form McGill Pain Questionnaire (SF-MPQ) immediately and 24, 48, 72, and 96 h after exercise. Data were analyzed with repeated-measures ANOVA. Results: Women with FM preferred a lower intensity of exercise than what was prescribed as indicated by significantly lower HR, watts, and RPE responses (P < 0.05). Muscle pain in the legs, however, was similar in the two conditions and significantly increased during exercise (P < 0.05). Pain thresholds and pain tolerances increased significantly after exercise, whereas peak pain ratings decreased after exercise (P < 0.05). Furthermore, pain (SF-MPQ) in the follow-up period was found to be lower than baseline (P < 0.05). Conclusions: It is concluded that the women with FM who participated in this study experienced significant improvements in pain after exercise. The results from this study are novel and indicate that recommendations for exercise prescription for individuals with FM should consider the preferred-intensity exercise model as a strategy to reduce pain.

AB Natural killer (NK) cells are bone marrow-derived granular lymphocytes that have a key role in immune defense against viral and bacterial infections and malignancies. NK cells are traditionally defined as cells of the innate immune response because they lack RAG recombinase-dependent clonal antigen receptors. However, evidence suggests that specific subsets of mouse NK cells can nevertheless develop long-lived and highly specific memory to a variety of antigens. Here we review published evidence of NK cell-mediated, RAG-independent adaptive immunity. We also compare and contrast candidate mechanisms for mammalian NK cell memory and antigen recognition with other examples of RAG-independent pathways that generate antigen receptor diversity in non-mammalian species and discuss NK cell memory in the context of lymphocyte evolution.

AB The transcription factor BATF controls the differentiation of interleukin 17 (IL-17)-producing helper T cells (T(H)17 cells) by regulating expression of the transcription factor ROR gamma t itself and ROR gamma t target genes such as Il17. Here we report the mechanism by which BATF controls in vivo class-switch recombination (CSR). In T cells, BATF directly controlled expression of the transcription factors Bcl-6 and c-Maf, both of which are needed for development of follicular helper T cells (T(FH) cells). Restoring T(FH) cell activity to Batf(-/-) T cells in vivo required coexpression of Bcl-6 and c-Maf. In B cells, BATF directly controlled the expression of both activation-induced cytidine deaminase (AID) and of germline transcripts of the intervening heavy-chain region and constant heavy-chain region (I(H)-C(H)). Thus, BATF functions at multiple hierarchical levels in two cell types to globally regulate switched antibody responses in vivo.

AB Cells comprising a tissue migrate as part of a collective. How collective processes are coordinated over large multi-cellular assemblies has remained unclear, however, because mechanical stresses exerted at cell-cell junctions have not been accessible experimentally. We report here maps of these stresses within and between cells comprising a monolayer. Within the cell sheet there arise unanticipated fluctuations of mechanical stress that are severe, emerge spontaneously, and ripple across the monolayer. Within that stress landscape, local cellular migrations follow local orientations of maximal principal stress. Migrations of both endothelial and epithelial monolayers conform to this behaviour, as do breast cancer cell lines before but not after the epithelial-mesenchymal transition. Collective migration in these diverse systems is seen to be governed by a simple but unifying physiological principle: neighbouring cells join forces to transmit appreciable normal stress across the cell-cell junction, but migrate along orientations of minimal intercellular shear stress.

AB Diffuse optical imaging (DOI) allows the recovery of the hemodynamic response associated with evoked brain activity. The signal is contaminated with systemic physiological interference which occurs in the superficial layers of the head as well as in the brain tissue. The back-reflection geometry of the measurement makes the DOI signal strongly contaminated by systemic interference occurring in the superficial layers. A recent development has been the use of signals from small source-detector separation (1 cm) optodes as regressors. Since those additional measurements are mainly sensitive to superficial layers in adult humans, they help in removing the systemic interference present in longer separation measurements (3 cm). Encouraged by those findings, we developed a dynamic estimation procedure to remove global interference using small optode separations and to estimate simultaneously the hemodynamic response. The algorithm was tested by recovering a simulated synthetic hemodynamic response added over baseline DOI data acquired from 6 human subjects at rest. The performance of the algorithm was quantified by the Pearson R-2 coefficient and the mean square error (MSE) between the recovered and the simulated hemodynamic responses. Our dynamic estimator was also compared with a static estimator and the traditional adaptive filtering method. We observed a significant improvement (two-tailed paired t-test, p < 0.05) in both HbO and HbR recovery using our Kalman filter dynamic estimator compared to the traditional adaptive filter, the static estimator and the standard GLM technique.

AB The onset of positive symptoms in schizophrenia is often preceded by a prodromal phase characterized by neurocognitive abnormalities as well as changes in brain structure and function. Increasing efforts have been made to identify individuals at elevated risk of developing schizophrenia, as early intervention may help prevent progression towards psychosis. The present study uses functional MRI and graph theoretical analysis to characterize the organization of a functional brain network in at-risk mental state patients with varying symptoms assessed with the PANSS and healthy volunteers during performance of a verbal fluency task known to recruit frontal lobe networks and to be impaired in psychosis. We first examined between-groups differences in total network connectivity and global network compactness/efficiency. We then addressed the role of specific brain regions in the network organization by calculating the node-specific "betweeness centrality", "degree centrality" and "local average path length" metrics: different ways of assessing a region's importance in a network. We focused our analysis on the anterior cingulate cortex (ACC): a region known to support executive function that is structurally and functionally impaired in at-risk mental state patients. Although global network connectivity and efficiency were maintained in at-risk patients relative to the controls, we report a significant decrease in the contribution of the ACC to task-relevant network organization in at risk subjects with elevated symptoms (PANSS 45) relative to both the controls and the less symptomatic at-risk subjects, as reflected by a reduction in the topological centrality of the ACC. These findings provide evidence of network abnormalities and anterior cingulate cortex dysfunction in people with prodromal signs of schizophrenia. (C) 2011 Elsevier Inc. Alrrights reserved.

AB In the present study, we sought to examine whether the fronto-striatal learning system, which has been implicated in bulimia nervosa, would demonstrate altered BOLD activity during probabilistic category learning in women who met subthreshold criteria for bulimia nervosa (Sub-BN). Sub-BN, which falls within the clinical category of Eating Disorder Not Otherwise Specified (EDNOS). is comprised of individuals who demonstrate recurrent binge eating, efforts to minimize their caloric intake and caloric retention, and elevated levels of concern about shape, weight, and/or eating, but just fail to meet the diagnostic threshold for bulimia nervosa (BN). fMRI data were collected from eighteen women with subthreshold-BN (Sub-BN) and nineteen healthy control women group-matched for age, education and body mass index (MC) during the weather prediction task. Sub-BN participants demonstrated increased caudate nucleus and dorsolateral prefrontal cortex (DLPFC) activation during the learning of probabilistic categories. Though the two subject groups did not differ in behavioral performance, over the course of learning, Sub-BN participants showed a dynamic pattern of brain activity differences when compared to matched control participants. Regions implicated in episodic memory, including the medial temporal lobe (MTL), retrosplenial cortex, middle frontal gyrus, and anterior and posterior cingulate cortex showed decreased activity in the Sub-BN participants compared to MCs during early learning which was followed by increased involvement of the DLPFC during later learning. These findings demonstrate that women with Sub-BN demonstrate differences in fronto-striatal learning system activity, as well as a distinct functional pattern between fronto-striatal and MTL learning systems during the course of implicit probabilistic category learning.

AB Aims and Methods: The alpha-synucleinopathy multiple system atrophy (MSA) and diseases defined by pathological 43-kDa transactive response DNA-binding protein (TDP-43) or fused in sarcoma (FUS) aggregates such as amyotrophic lateral sclerosis and frontotemporal lobar degeneration show overlapping clinico-pathological features. Consequently, we examined MSA for evidence of TDP-43 or FUS pathology utilizing immunohistochemical studies in autopsy material from 29 MSA patients. Results: TDP-43 pathology was generally rare, and there were no FUS lesions. The TDP-43 lesions were located predominantly in medio-temporal lobe and subcortical brain areas and were comprised mainly of dystrophic processes and perivascular (and subpial) lesions. Conclusions: The multisystem clinical symptoms and signs of MSA, and in particular the neurobehavioural/cognitive and pyramidal features, appear not to result from concomitant TDP-43 or FUS pathology, but rather from widespread white matter alpha-synuclein positive glial cytoplasmic inclusions and neurodegeneration in keeping with a primary alpha-synuclein-mediated oligodendrogliopathy. The gliodegenerative disease MSA evidently results from different pathogenetic mechanisms than neurodegenerative diseases linked to pathological TDP-43.

ID PRETERM DELIVERY; PREVENTION
AB U.S. Food and Drug Administration (FDA) approval of 17 alpha-hydroxyprogesterone caproate for the indication of decreasing the risk of preterm delivery in those high-risk patients who previously had spontaneous preterm birth has come at considerable cost to the health care system. Weekly injections provided by compounding pharmacies starting at 16-20 weeks of gestation and continuing until 36 weeks currently cost the health care system $200 to $300 per pregnancy. This cost is significantly less than the costs associated with delivering and caring for preterm children. Makena, by KV Pharmaceutical, the same 17 alpha-hydroxyprogesterone caproate product, is priced at $1,500 per injection, or a projected cost of $30,000 per pregnancy. With approximately 132,000 pregnancies being eligible for treatment annually, this increase in cost of 75-150 times what previously had been paid far exceeds the benefits derived from the FDA-approved Makena when compared with previously available compounded versions of 17 alpha-hydroxyprogesterone caproate. This increased health care cost is not justified at this time. The price barrier to access imposed by KV Pharmaceutical actually could result in an increase in preterm deliveries over current rates. Actions are needed by the FDA, national societies, and the manufacturer to ensure that all high-risk patients continue to get the needed therapy to reduce the number of preterm births.

ID FEBRILE NEUTROPHILIC DERMATOSIS; DISEASE; MANIFESTATIONS
AB Purpose: To report a case of a patient with optic nerve involvement in neuro-Sweet syndrome and review the literature on this systemic disease.
Methods: Interventional case report and review of the literature.
Results: A 49-year-old man developed an acute exacerbation of bilateral panuveitis and optic disc edema together with symptoms of a papular rash on his forearms, fevers, malaise, and arthalgias. Laboratory findings revealed an aseptic meningitis and neutrophilic leukocytosis. Biopsy of the skin rash demonstrated an intense neutrophilic infiltrate in the dermis consistent with the diagnosis of neuro-Sweet syndrome. The patient continued to require corticosteroids for inflammation control in spite of immunomodulatory therapies, including tumor necrosis factor-alpha inhibitor infliximab.
Conclusions: Sweet syndrome can present with optic nerve involvement. Screening for underlying etiologies, including autoimmune disease, malignancy, and offending drugs, is important for targeted therapy.

AB NAD(P)H:quinone oxidoreductase 1 (NQO1), is a cytosolic flavoenzyme that catalyzes the two-electron reduction of quinones into hydroquinones. A polymorphism (NQO1*2) alters enzymatic activity of NQO1 resulting in diminished NQO1 activity. Malignancies with NQO1*2 may be resistant to radiation and chemotherapy with resulting poorer survival. NQO1 allele was evaluated in subjects enrolled in ECOG 3590, a randomized comparison of radiation (RT) vs radiation and chemotherapy with cisplatin/etoposide (RCT) in patients with completely resected stages II and IIIa NSCLC. Overall survival was estimated using the Kaplan-Meier method and compared via the log-rank test. Cox models were used to assess the impact of covariates on outcomes. Among 152 patients with assessable samples, 24 (16%) had NQO1*2. Median follow-up was 139 months. The presence of NQO1*2/*2 was associated with decreased overall survival (OS) (median in the heterozygote/wild-type group 42.3 vs. 33.5 months in the variant group, p=0.04). In a multivariable Cox model, variant NQO1 (HR=1.58, p=0.05), age < 60 (HR=0.67, p=0.04), PS 1 (HR=1.47, p=0.05), cardiovascular disease (HR=1.93, p=0.003) and alkaline phosphatase < 100 mg/ml (HR=0.59, p=0.005) were all significant predictors of OS. NQO1*2/*2 may be an independent predictor of poor overall survival in individuals with resected stages II and IIIa NSCLC. Although the basis for the NQO1 association with decreased survival requires additional evaluation, NQO1 may represent a biomarker for guiding individualized therapy.

AB Recent studies have shown that leptin (an adipocytokine) played an important role in nociceptive behavior induced by nerve injury, but the cellular mechanism of this action remains unclear. Using the whole-cell patch-clamp recording from rat's spinal cord slices, we showed that superfusion of leptin onto spinal cord slices dose-dependently enhanced N-methyl-D-aspartate (NMDA) receptor-mediated currents in spinal cord lamina II neurons. At the cellular level, the effect of leptin on spinal NMDA-induced currents was mediated through the leptin receptor and the JAK2/STAT3 (but not PI3K or MAPK) pathway, as the leptin effect was abolished in leptin receptor-deficient (db/db) mice and inhibited by a JAK/STAT inhibitor. Moreover, we demonstrated in naive rats that a single intrathecal administration of leptin enhanced spontaneous biting, scratching, and licking behavior induced by intrathecal NMDA and that repeated intrathecal administration of leptin elicited thermal hyperalgesia and mechanical allodynia, which was attenuated by the noncompetitive NMDA receptor antagonist MK-801. Intrathecal leptin also upregulated the expression of NMDA receptors and pSTAT3 within the rat's spinal cord dorsal horn, and intrathecal MK-801 attenuated this leptin effect as well. Our data demonstrate a relationship between leptin and NMDA receptor-mediated spinal neuronal excitation and its functional role in nociceptive behavior. Since leptin contributes to nociceptive behavior induced by nerve injury, the present findings suggest an important cellular link between the leptin's spinal effect and the NMDA receptor-mediated cellular mechanism of neuropathic pain.

AB The role of microorganisms in the gastrointestinal tract has undergone significant modification in the past few decades with new observations from clinical, epidemiologic, and basic science research. We now know that the perception of these gut microbes as pathogens or even as commensals is somewhat outdated. It is becoming increasingly clear that the gut microbiome plays an important role in a host of activities including digestion, protection from potentially pathogenic organisms, and the regulation and development of the host immune system. The complex interactions between microbes and host combined with recent clinical observations and epidemiologic trends may point to the convergence of two well-supported (though imperfect) hypotheses: the "hygiene hypothesis" and the "fetal programming hypothesis." We are beginning to understand that exposure to microbes before conception, during gestation, and in the neonatal period have profound effects on the developing immune system. Recent observations from a variety of fields help support the expansion of the "fetal programming hypothesis" to a host-microbe corollary that microbe-host interactions at critical windows influence the future immune phenotype, the maintenance of immune health, and the development of immune-mediated disease.

AB Purpose Chondrocytes lose their ability to produce cartilaginous matrix during multiplication in culture through repeated passages, resulting in inferior tissue phenotype. To overcome the limited amount of primary chondrocytes, we aimed to determine the optimal culture condition for in vitro/in vivo cartilage regeneration using human adipose-derived mesenchymal stem cells (AMSCs).
Methods To evaluate the effects exerted by the chondrocytic culture condition on AMSC, we utilized chondrocyte conditioned medium (CM) and/or co-culture methods to prime and differentiate AMSCs. We evaluated ultimate in vivo engineered cartilage with primed AMSCs with that of chondrocytes. To examine the link between conditioned factors and proliferation/differentiation, cell cycle progression of AMSCs were examined using 5-ethynyl-2'-deoxyuridine (EdU), and gene expression was monitored.
Results We report that AMSCs can be stimulated to become chondrogenic cells when expanded with chondrocyte CM. Polymeric scaffolds co-seeded with CM-expanded AMSCs and primary chondrocytes resulted in in vivo cartilaginous tissues with similar biochemical content to constructs seeded with chondrocytes alone.
Conclusion These results indicate that chondrocyte CM consists of suitable morphogenetic factors that induce the chondrogenic priming of AMSCs for cartilage tissue engineering.

AB Qualitative researchers who explore the individual's experience of health, illness, death, and dying often experience emotional stress in their work. In this article, we describe the emotional stress we experienced while coding semistructured, after-death interviews conducted with 38 next of kin of deceased veterans. Coding sensitive topic data required an unexpected level of emotional labor, the impact of which has not been addressed in the literature. In writing this discussion article, we stepped back from our roles as interviewers/coders and reflected on how our work affected us individually and as a team, and how a sequence of exposures could exert a cumulative effect for researchers in such a dual role. Through this article, we hope to generate an expanded discourse on how qualitative inquiry impacts the emotional well-being of researchers.

AB Purpose: To obtain utilities (a unit of measure of a person's relative preferences for different health states compared with death or worst possible outcome) for uterine fibroids before and after treatment and to measure short-term utilities for the following uterine fibroid treatments: abdominal hysterectomy, magnetic resonance (MR) imaging-guided focused ultrasound surgery, and uterine artery embolization (UAE).
Materials and Methods: This retrospective study was approved by the institutional review board and was HIPAA compliant. The waiting trade-off (WTO) method, a variation on the time trade-off (TTO) method, is used to obtain utilities for diagnostic procedures on the basis of the fact that people wait longer to avoid noxious tests and/or procedures. The WTO method provides short-term quality of life tolls in terms of quality-adjusted life-weeks by scaling wait times with pre-and posttreatment utilities. Utilities for uterine fibroids before and after treatment were obtained with the TTO method and a visual analog scale (VAS) by using a questionnaire administered by means of a phone interview. WTO wait times were adjusted for quality of life with VAS and TTO utilities and a transformation of VAS. Wait times were compared by using nonparametric tests. The study participants included 62 patients who had undergone abdominal hysterectomy, 74 who had undergone UAE, and 61 who had undergone MR imaging-guided focused ultrasound surgery.
Results: Quality of life increased with all treatments. The median WTO wait time was higher for hysterectomy (21.6 weeks) than for UAE or MR imaging-guided focused ultrasound surgery (14.1 weeks for both) (P < .05). Quality-adjusted life-week tolls were smaller when scaled according to TTO than when scaled according to VAS or transformation of VAS.
Conclusion: Quality of life increased after all fibroid treatments. WTO is feasible for assessing the quality-adjusted morbidity of treatment procedures. (C) RSNA, 2011

AB Background Bariatric surgery is a rapidly growing field. Advances in surgical technologies and techniques have raised concerns about patient safety. Bariatric surgeons and programs are under increased scrutiny from regulatory agencies, insurers, and public health officials to provide high quality and safe care for bariatric patients at all phases of care.
Methods During the 2009 annual meeting of the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES), a panel of experts convened to provide updated information on patient safety and best practices in bariatric surgery. The following article is a summary of this panel presentation.
Results and Conclusions Weight loss surgery is a field that is evolving and adapting to multiple external pressures. Safety concerns along with increasing public scrutiny have led to a systematic approach to defining best practices, creating standards of care, and identifying mechanisms to ensure that patients consistently receive the best and most effective care possible. In many ways, bariatric surgery and multidisciplinary bariatric surgery programs may serve as a model for other programs and surgical specialties in the near future.

TI Spinal metastasis of endometrial stromal sarcoma: Clinicopathological

DE Endometrial stromal sarcoma; Metastasis; Thoracic spine; Spinal tumor;
Immunohistochemical
ID SMOOTH-MUSCLE TUMORS; EXPRESSION; NEOPLASMS; THERAPY; CORD; CD10
AB Background: Endometrial Stromal Sarcoma(ESS) is a rare uterine malignancy which often metastasizes several years after initial diagnosis. Thoracic spine is a rare ESS metastatic site and its proper management is still not a consensus. We discuss the histopathological features and the management strategies through an illustrative case of a 77 year-old woman with metastasis to the thoracic spine 13 years after total hysterectomy for ESS.
Methods: Review of the literature and identification of 5 patients, including our present case, with ESS involving the spinal cord. We discuss the outcomes achieved after each therapy. In our case, the patient presented a mass involving the thoracic spinal canal constricting the spinal cord at T7 level. A two-level decompression laminectomy was performed and the lesion was partially excised.
Results: The histopathological along with the immunohistochemical profile mitotic rate indicated the endometrial stromal cells origin of the tumor, confirming the diagnosis of a low-grade ESS metastasis. The patient was managed with surgery in combination with postoperative radiation therapy.
Conclusions: The small number of published cases precludes definitive conclusions regarding standard management. However, it seems that treatment of metastatic ESS to the spine matches the same general concepts of spine metastasis, namely surgery followed by radiation therapy, due to clinical improvement and long-term disease control of the reported cases. Hormonal therapy may be considered in recurrent disease with strong expression of estrogen and progesterone receptors. However, these findings need confirmation in larger studies.

TI The Effect of Removing Cost as a Barrier to Treatment Initiation With
Outpatient Tobacco Dependence Clinics Among Emergency Department
Patients
SO ACADEMIC EMERGENCY MEDICINE
LA English
DT Article
ID SMOKING; INTERVENTION
AB Objectives: The campaign against tobacco addiction and smoking continues to play an important role in public health. However, referrals to outpatient tobacco cessation programs by emergency physicians are rarely pursued by patients following discharge. This study explored cost as a barrier to follow-up.
Methods: The study was performed at a large urban hospital emergency department (ED) in Camden, New Jersey. Enrollment included adults who reported tobacco use in the past 30 days. Study participants were informed about a "Stop Smoking Clinic" affiliated with the hospital and, depending on enrollment date, cost of treatment was advertised as $150 (standard fee), $20 (reduced fee), or $0 (no fee). Monitoring of patient inquiries and visits to the clinic was performed for 6 months following enrollment of the last study subject.
Results: The analyzed sample consisted of 577 tobacco users. There were no statistically significant demographic differences between treatment groups (p > 0.05). Two-hundred forty-seven (43%) participants reported "very much" interest in smoking cessation. However, there was no significant difference in initiating treatment with the Stop Smoking Clinic across experimental condition. Only a single subject, enrolled in the no-fee phase, initiated treatment with the clinic.
Conclusions: Cost is unlikely to be the only barrier to pursing outpatient tobacco treatment after an ED visit. Further research is needed to determine the critical components of counseling and referral that maximize postdischarge treatment initiation.

TI A Brain-Permeable Small Molecule Reduces Neuronal Cholesterol by
Inhibiting Activity of Sirtuin 2 Deacetylase
SO ACS CHEMICAL BIOLOGY

DT Article
ID HUNTINGTONS-DISEASE; MODELS
AB Sirtuin 2 (SIRT2) deacetylase-dependent inhibition mediates neuroprotective reduction of cholesterol biosynthesis in an in vitro Huntington's disease model. This study sought to identify the first brain permeable SIRT2 inhibitor and to characterize its cholesterol-reducing properties in neuronal models. Using biochemical sirtuin deacetylation assays, we screened a brain-permeable in silico compound library, yielding 3-(1-azepanyl-sulfonyl)-N-(3-bromphenyl)benzamide as the most potent and selective SIRT2 inhibitor. Pharmacokinetic studies demonstrated brain-permeability but limited metabolic stability of the selected candidate. In accordance with previous observations, this SIRT2 inhibitor stimulated cytoplasmic retention of sterol regulatory element binding protein-2 and subsequent transcriptional down-regulation of cholesterol biosynthesis genes, resulting in reduced total cholesterol in primary striatal neurons. Furthermore, the identified inhibitor reduced cholesterol in cultured naive neuronal cells and brain slices from wild-type mice. The outcome of this study provides a clear opportunity for lead optimization and drug development, targeting metabolic dysfunctions in CNS disorders where abnormal cholesterol homeostasis is implicated.

AB In the absence of effective antiretroviral therapy, infection with clade B human immunodeficiency virus (HIV-1) infection commonly progresses to AIDS dementia. However, in India, where clade C infection is most prevalent, severe cognitive impairment due to HIV-1 is reported to be less prevalent. The Tat protein of HIV-1, which is released from HIV-1-infected macrophages, is thought to play a major role in the disruption of neuronal function as well as in the infiltration of macrophages associated with advanced neuropathogenesis. Clade B Tat is excitotoxic to hippocampal neurons by potentiating N-methyl-D-aspartate-induced currents of the zinc-sensitive NR1/NR2A N-methyl-D-aspartate receptor in a zinc-binding-dependent mechanism. This study characterizes the zinc-binding properties of clade C Tat protein. Using ultraviolet spectroscopy and the Ellman reaction, we show that clade C Tat protein binds just one zinc ion per monomer. We then investigated the ability of clade C Tat to block the inhibition of N-methyl-D-aspartate receptors from zinc antagonism through ion chelation. Although clade C Tat enhanced N-methyl-D-aspartate-mediated rat hippocampus neuronal toxicity in the presence of zinc, the increase was significantly less than that observed with clade B Tat. These findings suggest that the observed differences in neuropathogenesis found with HIV-1 clade C infection compared to clade B may, in part, be due to a decrease in Tat-mediated neurotoxicity.

AB Limb deficiencies, the congenital absence or hypoplasia of a long bone and/or digits, vary greatly in their anatomy and etiology. Previous attempts to classify the range of possible phenotypes have not included all types of deficiencies. We present a new classification system, which includes all potential phenotypes. Infants with limb deficiencies were identified in the hospital-based Active Malformations Surveillance Program at Brigham and Women's Hospital in Boston, MA from the years 1972 to 1974 and 1979 to 2000. Affected infants were classified based on the anatomy and apparent cause of their deficiencies. The prevalence rate of all types of limb deficiency was 0.79/1,000. Upper limb deficiencies were significantly more common than lower limb deficiencies. There was no significant difference in frequencies between deficiencies on the left and right sides of the body. Longitudinal defects were more common than terminal transverse defects; intercalary defects were uncommon. Longitudinal defects were most likely to occur on the preaxial side of the limb. Almost half of affected infants had affected digits, with normal long bones. The most common apparent cause of limb deficiencies was vascular disruption defects (0.22/1,000), such as amniotic band-related limb deficiency. This new classification system includes deficiency of each long bone, as well as absence of any finger or toe. This system will make it possible to establish the prevalence of each specific phenotype. The large number of distinct apparent causes illustrates the marked etiologic heterogeneity of limb deficiencies. (C) 2011 Wiley-Liss, Inc.

TI Alternative Processing of gamma-Secretase Substrates in Common Forms of
Mild Cognitive Impairment and Alzheimer's Disease: Evidence for
gamma-Secretase Dysfunction
SO ANNALS OF NEUROLOGY
LA English
DT Article
ID BETA-PROTEIN PRECURSOR; IN-VIVO; METABOLISM; CLEAVAGE; MEMBRANE;
ALCADEIN; ENZYME; BRAIN; RATIO
AB Objective: The most common pathogenesis for familial Alzheimer's disease (FAD) involves misprocessing (or alternative processing) of the amyloid precursor protein (APP) by gamma-secretase due to mutations of the presenilin 1 (PS1) gene. This misprocessing/alternative processing leads to an increase in the ratio of the level of a minor gamma-secretase reaction product (A beta 42) to that of the major reaction product (A beta 40). Although no PS1 mutations are present, altered A beta 42/40 ratios are also observed in sporadic Alzheimer's disease (SAD), and these altered ratios apparently reflect deposition of A beta 42 as amyloid.
Methods: Using immunoprecipitation-mass spectrometry with quantitative accuracy, we analyzed in the cerebrospinal fluid (CSF) of various clinical populations the peptide products generated by processing of not only APP but also an unrelated protein, alcadein (Alc). Alc undergoes metabolism by the identical APP alpha-secretases and gamma-secretases, yielding a fragment that we have named p3-Alca because of the parallel genesis of p3-Alc(alpha) peptides and the p3 fragment of APP. As with A beta, both major and minor p3-Alc(alpha)s are generated. We studied the alternative processing of p3-Alc(alpha) in various clinical populations.
Results: We previously reported that changes in the A beta 42/40 ratio showed covariance in a linear relationship with the levels of p3-Alc(alpha) [minor/major] ratio in media conditioned by cells expressing FAD-linked PS1 mutants. Here we studied the speciation of p3-Alc(alpha) in the CSF from 3 groups of human subjects (n 158): elderly nondemented control subjects; mild cognitive impairment (MCI) subjects with a clinical dementia rating (CDR) of 0.5; SAD subjects with CDR of 1.0; and other neurological disease (OND) control subjects. The CSF minor p3-Alc(alpha) variant, p3-Alc(alpha)38, was elevated (p < 0.05) in MCI subjects or SAD subjects, depending upon whether the data were pooled and analyzed as a single cohort or analyzed individually as 3 separate cohorts.
Interpretation: These results suggest that some SAD may involve alternative processing of multiple c-secretase substrates, raising the possibility that the molecular pathogenesis of SAD might involve gamma-secretase dysfunction. ANN NEUROL 2011;69:1026-1031

AB Objective: Both amyloid-beta (A beta) deposition and brain atrophy are associated with Alzheimer's disease (AD) and the disease process likely begins many years before symptoms appear. We sought to determine whether clinically normal (CN) older individuals with A beta deposition revealed by positron emission tomography (PET) imaging using Pittsburgh Compound B (PiB) also have evidence of both cortical thickness and hippocampal volume reductions in a pattern similar to that seen in AD.
Methods: A total of 119 older individuals (87 CN subjects and 32 patients with mild AD) underwent PiB PET and high-resolution structural magnetic resonance imaging (MRI). Regression models were used to relate PiB retention to cortical thickness and hippocampal volume.
Results: We found that PiB retention in CN subjects was (1) age-related and (2) associated with cortical thickness reductions, particularly in parietal and posterior cingulate regions extending into the precuneus, in a pattern similar to that observed in mild AD. Hippocampal volume reduction was variably related to Ab deposition.
Interpretation: We conclude that Ab deposition is associated with a pattern of cortical thickness reduction consistent with AD prior to the development of cognitive impairment. ANN NEUROL 2011;69:1032-1042
