Background Nivolumab plus ipilimumab produced objective responses in patients with advanced renal-cell carcinoma in a pilot study. This phase 3 trial compared nivolumab plus ipilimumab with sunitinib for previously untreated clear-cell advanced renal-cell carcinoma. Methods We randomly assigned adults in a 1:1 ratio to receive either nivolumab (3 mg per kilogram of body weight) plus ipilimumab (1 mg per kilogram) intravenously every 3 weeks for four doses, followed by nivolumab (3 mg per kilogram) every 2 weeks, or sunitinib (50 mg) orally once daily for 4 weeks (6-week cycle)...

Inhibitors targeting BCL-2 apoptotic proteins have significant potential for the treatment of acute myeloid leukemia (AML); however, complete responses are observed in only 20% of patients suggesting targeting BCL-2 alone is insufficient to yield durable responses. Here we assessed the efficacy of co-administration of the PI3K/mTOR inhibitor GDC-0980 or the p110β-sparing PI3K inhibitor taselisib with the selective BCL-2 antagonist venetoclax in AML cells. Tetracycline-inducible downregulation of BCL-2 significantly sensitized MV4-11 and MOLM-13 AML cells to PI3K inhibition...

BACKGROUND: Chronic hepatitis B infection is a significant cause of morbidity and mortality worldwide; low- and middle-income countries (LMICs) are disproportionately affected. Economic evaluations are a useful decision tool to assess costs versus benefits of hepatitis B virus (HBV) screening. No published study reviewing economic evaluations of HBV screening in LMICs has been undertaken to date. METHODS: The following databases were searched from inception to 21 April 2017: MEDLINE, PubMed, EMBASE, CINAHL Plus, the Cochrane Library, Global Health and the Cost-effectiveness Analysis Registry...

BACKGROUND: Obtaining National Institutes of Health (NIH) R01 funding remains extremely difficult. The utility of career development grants (K awards) for achieving the goal of R01 funding remains debated, particularly for surgeon-scientists. We examined the success rate for cardiothoracic and vascular (CTV) surgeons compared to other specialties in converting K-level grants into R01 equivalents. METHODS: All K (K08 and K23) grants awarded to surgeons by the NIH between 1992-2017 were identified through NIH RePORTER, an online database combining funding, publications, and patents...

Healthcare institutions, accreditation agencies for higher learning, and organizations such as the National Academy of Medicine in the United States, support interprofessional education (IPE) opportunities. However, incorporating IPE opportunities into academic settings remains difficult. One challenge is assessing IPE learning and practice outcomes, especially at the level of student performance to ensure graduates are "collaboration-ready". The Creighton-Interprofessional Collaborative Evaluation (C-ICE) instrument was developed to address the need for a measurement tool for interprofessional student team performance...

Aplastic anemia is a hematologic condition occasionally presenting during pregnancy. This pathological process is associated with significant maternal and neonatal morbidity and mortality. Obstetric and anesthetic management is challenging, and treatment requires a coordinated effort by an interdisciplinary team, in order to provide safe care to these patients. In this review, we describe the current state of the literature as it applies to the complexity of aplastic anemia in pregnancy, focusing on pathophysiologic aspects of the disease in pregnancy, as well as relevant obstetric and anesthetic considerations necessary to treat this challenging problem...

How climate affects species distributions is a longstanding question receiving renewed interest owing to the need to predict the impacts of global warming on biodiversity. Is climate change forcing species to live near their critical thermal limits? Are these limits likely to change through natural selection? These and other important questions can be addressed with models relating geographical distributions of species with climate data, but inferences made with these models are highly contingent on non-climatic factors such as biotic interactions...

BACKGROUND: Frailty is an important predictor of outcomes after cardiac surgery, but utility is limited by difficult assessment and quantification. We hypothesize that sarcopenia defined as psoas muscle cross-sectional area is a useful predictor of surgical aortic valve replacement (SAVR) outcomes in moderate to high-risk patients. METHODS: Moderate to high-risk (predicted risk of mortality [PROM] >3%) patients who underwent SAVR with or without coronary bypass were extracted from an institutional database (2009-2016)...

BACKGROUND: As a marker of myocardial injury, troponin level correlates with adverse outcomes following myocardial infarction (MI). We hypothesized that patients with higher preoperative troponin level would have increased morbidity and mortality following CABG. METHODS: A total of 1,272 patients underwent urgent or emergent, isolated CABG and had preoperative troponin measurements at our institution (2002-2016). Logistic regression assessed the risk-adjusted impact of peak troponin level on morbidity and mortality...

The pathology of migraine, a common neurological disease, involves sensitization and activation of trigeminal nociceptive neurons to promote hyperalgesia and allodynia during an attack. Migraineurs often exhibit characteristics of a hyperexcitable or hypervigilant nervous system. One of the primary reported risk factors for development of a hyperexcitable trigeminal system is chronic, unmanaged stress and anxiety. While primary traumatic stress is a commonly cited risk factor for many pain conditions, exposure to secondary traumatic stress early in life is also thought to be a contributing risk factor...

Despite the extensive literature on the tobacco industry, there has been little attempt to study how transnational tobacco companies (TTCs) coordinate their political activities globally, or to theorise TTC strategies within the context of global governance structures and policy processes. This article draws on three concepts from political science - policy transfer, multi-level governance and venue shifting - to analyse TTCs' integrated, global strategies to oppose augmented packaging requirements across multiple jurisdictions...

Men's perpetration of intimate partner violence (IPV) is common, but its multilevel determinants are understudied. We leveraged novel data from a probability sample of 570 junior men (married, 18-34 years) from 50 urban and 62 rural communities who took part in the Bangladesh survey of the 2011 UN Multi-Country Study of Men and Violence . We tested whether more equitable community gender norms among senior men (N=938; married, 35-49 years) was negatively associated, and a junior man's greater exposure to childhood violence was positively associated, with his lifetime count (or scope) of physical IPV acts perpetrated...

Chlamydiaceae bacteria infect many vertebrate hosts, and previous reports based on polymerase chain reaction (PCR) assays and serologic assays that are prone to cross-reaction among chlamydial organisms have been used to describe the prevalence of either DNA fragments or antibodies to Chlamydia spp. in wild raptorial populations. This study reports the PCR-based prevalence of Chlamydiaceae DNA that does not 100% match any avian or mammalian Chlamydiaceae in wild populations of hawks in California Buteo species...

BACKGROUND: On 22 February 2011 an earthquake (magnitude 6.3) hit Christchurch, New Zealand. Earthquakes have been associated with increased risks of preterm birth (PTB) and other adverse pregnancy outcomes. However, the literature on this subject is scarce. Maternal antenatal stress has been suggested as the link between earthquakes and PTB. In this study the Christchurch earthquake was utilised as a model of maternal stress to assess its effects on PTB rates and other pregnancy outcomes...

Application of metabolic magnetic resonance imaging measures such as cerebral blood flow in translational medicine is limited by the unknown link of observed alterations to specific neurophysiological processes. In particular, the sensitivity of cerebral blood flow to activity changes in specific neurotransmitter systems remains unclear. We address this question by probing cerebral blood flow in healthy volunteers using seven established drugs with known dopaminergic, serotonergic, glutamatergic and GABAergic mechanisms of action...
