TL;DR: The combination of dabrafenib plus trametinib has activity in a subset of patients with BRAF V600-mutant mCRC, and mutational analysis revealed that the patient achieving a complete response and two of three evaluable patients achieving a partial response had PIK3CA mutations.
Abstract: Purpose To evaluate dabrafenib, a selective BRAF inhibitor, combined with trametinib, a selective MEK inhibitor, in patients with BRAF V600–mutant metastatic colorectal cancer (mCRC). Patients and Methods A total of 43 patients with BRAF V600–mutant mCRC were treated with dabrafenib (150 mg twice daily) plus trametinib (2 mg daily), 17 of whom were enrolled onto a pharmacodynamic cohort undergoing mandatory biopsies before and during treatment. Archival tissues were analyzed for microsatellite instability, PTEN status, and 487-gene sequencing. Patient-derived xenografts were established from core biopsy samples. Results Of 43 patients, five (12%) achieved a partial response or better, including one (2%) complete response, with duration of response > 36 months; 24 patients (56%) achieved stable disease as best confirmed response. Ten patients (23%) remained in the study > 6 months. All nine evaluable during-treatment biopsies had reduced levels of phosphorylated ERK relative to pretreatment biopsies (avera...

TL;DR: The purpose of this paper is to begin to untangle the contradictions and address some of the gaps by tracing the mechanisms and moderating processes through which identification develops in hybrid and pure virtual settings, and the ways that these processes differ from face-to-face settings.
Abstract: Identification is a person's sense of belonging with a social category. Identification in virtual organizational teams is thought to be especially desirable because it provides the glue that can promote group cohesion despite the relative lack of face-to-face interaction. Though research on virtual teams is exploding, it has not systematically identified the antecedents or moderators of the process by which identification develops, leaving a number of gaps and apparent contradictions. The purpose of this paper is to begin to untangle the contradictions and address some of the gaps by tracing the mechanisms and moderating processes through which identification develops in hybrid and pure virtual settings, and the ways that these processes differ from face-to-face settings.

TL;DR: To examine the potential role of endothelium-derived relaxing factor (EDRF) in regulation of the perinatal pulmonary circulation, the hemodynamic effects of a selective inhibitor of EDRF production, nitro-L-arginine (L-NA), on pulmonary vascular tone and dilator reactivity in the late-gestation ovine fetus and on the pulmonary vasodilation that normally occurs at birth are studied.
Abstract: To examine the potential role of endothelium-derived relaxing factor (EDRF) in regulation of the perinatal pulmonary circulation, we studied the hemodynamic effects of a selective inhibitor of EDRF production, nitro-L-arginine (L-NA), on pulmonary vascular tone and dilator reactivity in the late-gestation ovine fetus and on the pulmonary vasodilation that normally occurs at birth. L-NA infusion decreased pulmonary blood flow from 78 +/- 8 to 65 +/- 6 ml/min (P less than 0.01) and increased pulmonary artery pressure from 48 +/- 2 to 54 +/- 3 mmHg (P less than 0.002, n = 8 animals). To study the selectivity of L-NA on vasodilator responses to endothelium-dependent (acetylcholine) and -independent (atrial natriuretic factor) stimuli, we measured responses to brief infusions of each dilator before and after L-NA treatment. Acetylcholine increased pulmonary blood flow during the control period but not after L-NA treatment. In contrast, L-NA had little effect on the vasodilator response to atrial natriuretic factor. To study the role of EDRF in the transition of the pulmonary circulation from fetal to neonatal conditions, we infused L-NA into the left pulmonary artery immediately before cesarean-section delivery. In comparison with control animals, the rise in pulmonary blood flow at 1 h after delivery was reduced in the L-NA-treated animals (331 +/- 28 in control vs. 185 +/- 16 ml/min in treated, P less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

TL;DR: These findings support a model in which PRC2's promiscuous binding to RNA transcripts allows it to scan for target genes that have escaped repression, thus leading to maintenance of the repressed state.
Abstract: Polycomb repressive complex 2 (PRC2) is a histone methyltransferase required for epigenetic silencing during development and cancer, and it can be recruited to chromatin by long noncoding RNAs. In vitro binding studies and comparative analysis of genome-wide in vivo data now suggest a model for the maintenance of the repressed chromatin state by PRC2, directed by PRC2's promiscuous binding to nascent RNA transcripts.

TL;DR: These findings should be helpful in discussions with patients undergoing TAVR in US clinical practice, and at 1-year follow-up, overall mortality was 23.7%, the stroke rate was 4.1%, and the rate of the composite outcome of death and stroke was 26.0.
Abstract: Importance Introducing new medical devices into routine practice raises concerns because patients and outcomes may differ from those in randomized trials. Objective To update the previous report of 30-day outcomes and present 1-year outcomes following transcatheter aortic valve replacement (TAVR) in the United States. Design, Setting, and Participants Data from the Society of Thoracic Surgeons/American College of Cardiology (STS/ACC) Transcatheter Valve Therapies Registry were linked with patient-specific Centers for Medicare & Medicaid Services (CMS) administrative claims data. At 299 US hospitals, 12 182 patients linked with CMS data underwent TAVR procedures performed from November 2011 through June 30, 2013, and the end of the follow-up period was June 30, 2014. Exposure Transcatheter aortic valve replacement. Main Outcomes and Measures One-year outcomes including mortality, stroke, and rehospitalization were evaluated using multivariate modeling. Results The median age of patients was 84 years and 52% were women, with a median STS Predicted Risk of Operative Mortality (STS PROM) score of 7.1%. Following the TAVR procedure, 59.8% were discharged to home and the 30-day mortality was 7.0% (95% CI, 6.5%-7.4%) (n = 847 deaths). In the first year after TAVR, patients were alive and out of the hospital for a median of 353 days (interquartile range, 312-359 days); 24.4% (n = 2074) of survivors were rehospitalized once and 12.5% (n = 1525) were rehospitalized twice. By 1 year, the overall mortality rate was 23.7% (95% CI, 22.8%-24.5%) (n = 2450 deaths), the stroke rate was 4.1% (95% CI, 3.7%-4.5%) (n = 455 stroke events), and the rate of the composite outcome of mortality and stroke was 26.0% (25.1%-26.8%) (n = 2719 events). Characteristics significantly associated with 1-year mortality included advanced age (hazard ratio [HR] for ≥95 vs Conclusions and Relevance Among patients undergoing TAVR in US clinical practice, at 1-year follow-up, overall mortality was 23.7%, the stroke rate was 4.1%, and the rate of the composite outcome of death and stroke was 26.0%. These findings should be helpful in discussions with patients undergoing TAVR.
