TL;DR: First-line therapy with pembrolizumab in patients with advanced Merkel-cell carcinoma was associated with an objective response rate of 56% and effectiveness was correlated with tumor viral status, as assessed by serologic and immunohistochemical testing.
Abstract: BackgroundMerkel-cell carcinoma is an aggressive skin cancer that is linked to exposure to ultraviolet light and the Merkel-cell polyomavirus (MCPyV). Advanced Merkel-cell carcinoma often responds to chemotherapy, but responses are transient. Blocking the programmed death 1 (PD-1) immune inhibitory pathway is of interest, because these tumors often express PD-L1, and MCPyV-specific T cells express PD-1. MethodsIn this multicenter, phase 2, noncontrolled study, we assigned adults with advanced Merkel-cell carcinoma who had received no previous systemic therapy to receive pembrolizumab (anti–PD-1) at a dose of 2 mg per kilogram of body weight every 3 weeks. The primary end point was the objective response rate according to Response Evaluation Criteria in Solid Tumors, version 1.1. Efficacy was correlated with tumor viral status, as assessed by serologic and immunohistochemical testing. ResultsA total of 26 patients received at least one dose of pembrolizumab. The objective response rate among the 25 patient...

TL;DR: It is demonstrated that OT acts in the medial amygdala during the initial exposure to facilitate social recognition in the mouse, and OT given before, but not after, the initial encounter restores social Recognition in OT knock-out mice.
Abstract: Oxytocin (OT) knock-out mice fail to recognize familiar conspecifics after repeated social exposures, despite normal olfactory and spatial learning abilities. OT treatment fully restores social recognition. Here we demonstrate that OT acts in the medial amygdala during the initial exposure to facilitate social recognition. OT given before, but not after, the initial encounter restores social recognition in OT knock-out mice. Using c-Fos immunoreactivity (Fos-IR) as a marker of neuronal activation in this initial encounter, we found similar neuronal activation in the wild-type (WT) and OT knock-out mouse in olfactory bulbs, piriform cortex, cortical amygdala, and the lateral septum. Wild-type, but not OT knock-out mice exhibited an induction of Fos-IR in the medial amygdala. Projections sites of the medial amygdala also failed to show a Fos-IR induction in the OT knock-out mice. OT knock-out, but not WT, mice showed dramatic increases in Fos-IR in the somatosensory cortex and the hippocampus, suggesting alternative processing of social cues in these animals. With site-specific injections of OT and an OT antagonist, we demonstrate that OT receptor activation in the medial amygdala is both necessary and sufficient for social recognition in the mouse.

TL;DR: African-American participants in this study described distrust of the medical community as a prominent barrier to participation in clinical research.
Abstract: OBJECTIVE: To describe barriers to participation of African Americans in research. DESIGN: Focus group interviews conducted in 1997. PATIENTS: Thirty-three African-American adults presenting to an urban public hospital for outpatient medical care participated in one of five focus groups. MEASUREMENTS AND MAIN RESULTS: African-American patients' attitudes toward medical research were measured. Mistrust of doctors, scientists, and the government was reported consistently by the participants. Many participants described concerns about the ethical conduct of clinicians and investigators when poor or minority patients are involved and cited examples of exploitation as supporting evidence for their mistrust of the medical establishment. While participants were clear about the violation of human rights in the Tuskegee Syphilis Study, all were misinformed of the historical facts of the study. Few participants understood the concept of informed consent. Participants saw signing the document as relinquishing their autonomy and as a legal protection for physicians. Despite these concerns, participants gave recommendations to improve minority participation in research. CONCLUSIONS: African-American participants in this study described distrust of the medical community as a prominent barrier to participation in clinical research. Participants described real and perceived examples of exploitation to support their distrust of researchers. The goal of the consent process, to inform patients of risks and benefits so as to facilitate self-determination, was misinterpreted by these participants. Understanding the importance of interpersonal trust within the clinical relationship may prove to be a significant factor in enhancing participation in clinical trials.

TL;DR: The AABB developed this guideline to provide clinical recommendations about hemoglobin concentration thresholds and other clinical variables that trigger RBC transfusions in hemodynamically stable adults and children.
Abstract: Description: Although approximately 85 million units of red blood cells (RBCs) are transfused annually worldwide, transfusion practices vary widely The AABB (formerly, the American Association of Blood Banks) developed this guideline to provide clinical recommendations about hemoglobin concentration thresholds and other clinical variables that trigger RBC transfusions in hemodynamically stable adults and children Methods: These guidelines are based on a systematic review of randomized clinical trials evaluating transfusion thresholds We performed a literature search from 1950 to February 2011 with no language restrictions We examined the proportion of patients who received any RBC transfusion and the number of RBC units transfused to describe the effect of restrictive transfusion strategies on RBC use To determine the clinical consequences of restrictive transfusion strategies, we examined overall mortality, nonfatal myocardial infarction, cardiac events, pulmonary edema, stroke, thromboembolism, renal failure, infection, hemorrhage, mental confusion, functional recovery, and length of hospital stay Recommendation 1: The AABB recommends adhering to a restrictive transfusion strategy (7 to 8 g/dL) in hospitalized, stable patients (Grade: strong recommendation; high-quality evidence) Recommendation 2: The AABB suggests adhering to a restrictive strategy in hospitalized patients with preexisting cardiovascular disease and considering transfusion for patients with symptoms or a hemoglobin level of 8 g/dL or less (Grade: weak recommendation; moderate-quality evidence) Recommendation 3: The AABB cannot recommend for or against a liberal or restrictive transfusion threshold for hospitalized, hemodynamically stable patients with the acute coronary syndrome (Grade: uncertain recommendation; very low-quality evidence) Recommendation 4: The AABB suggests that transfusion decisions be influenced by symptoms as well as hemoglobin concentration (Grade: weak recommendation; low-quality evidence)
