Objective: To evaluate the impacts of an on-pump beating-heart versus an off-pump coronary artery bypass grafting (CABG) technique for surgical revascularization on the early clinical outcomes in patients with a left ventricular ejection fraction (EF) of 35% or less. Methods: A total of 216 consecutive patients with an echocardiographic estimated EF of 35% or less who underwent non-emergency, primary, isolated CABG from January 2010 to December 2014 at Department of Cardiovascular Surgery, Zhongshan Hospital, Fudan University were included in this study and were divided into either an OBCAB group (patients who received on-pump beating-heart CABG surgery, n =88) or an OPCAB group (patients who received off-pump CABG surgery, n =128)...

Objective: To analysis the curative effect of emergency cholecystectomy (EC) and percutaneous transhepatic gallbladder drainage (PTGBD) followed by delayed cholecystectomy (DC) on the patients with moderate acute cholecystitis. Methods: The perioperative dataof patients in EC group ( n =47) and in PTGBD-DC group ( n =49) were compared retrospectively. Results: Compared to PTGBD+ DC group, EC patients had a significantly more postoperative abdominal drainage time [(9.0±12.9) vs (3.4±2.1) days, P =0.041], more postoperative hospital stay after cholecystectomy [(8...

Medical publishing has become a pivotal aspect of all stages of career development in medicine in Belgium. Publication pressure is therefore present from the stage of the medical student to the level of the head of an academic medical service. This pressure represents a real danger to commit scientific misconduct, ranging from minor missteps to severe fraud. Recent surveys have shown that scientific misconduct and publication fraud represent an important problem in medical publishing, more than in other scientific fields, also in Belgium...

Background and Objectives: Approximately half the care for people with dementia is provided by families. It is therefore imperative that research informs ways of maintaining such care. In this study, we propose that a needs-led approach can provide a useful, novel means of conceptualizing the impact of caring on the lives of family carers. Our aim was to develop and present a needs-led framework for understanding how providing care impacts on carers' fulfilment of needs. Design and Methods: In this qualitative study, we conducted 42 semistructured interviews with a purposively diverse sample of family carers to generate nuanced contextualized accounts of how caring impacted on carers' lives...

Background: The pharmacodynamics of inhaled antimicrobials are poorly studied. Amikacin is being developed for inhalational therapy as BAY 41-6551. Objectives: We employed an in vitro pharmacokinetic model to study the pharmacokinetics/pharmacodynamics of amikacin. Methods: A dose-ranging design was used to establish fAUC/MIC and fCmax/MIC targets for static, -1 log drop and -2 log drop effects for strains of Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa...

This article uses a 1903 text by the Irish cookery instructress Kathleen Ferguson to examine the intersections between food, medicine and domestic work. Sick Room Cookery, and numerous texts like it, drew on traditions of domestic medicine and Anglo-Irish gastronomy while also seeking to establish female expertise informed by modern science and medicine. Placing the text in its broader cultural context, the article examines how it fit into the tradition of domestic medicine and the emerging profession of domestic science...

The current manuscript is the Executive Summary of the second update to the original Practical Guide, published in 2013. Non-vitamin K antagonist oral anticoagulants (NOACs) are an alternative for vitamin K antagonists (VKAs) to prevent stroke in patients with atrial fibrillation (AF), and have emerged as the preferred choice, particularly in patients newly started on anticoagulation. Both physicians and patients are becoming more accustomed to the use of these drugs in clinical practice. However, many unresolved questions on how to optimally use these agents in specific clinical situations remain...

The emergence of Arabidopsis as a model species and the availability of genetic and genomic resources have resulted in the identification and detailed characterisation of abiotic stress signalling pathways. However, this has led only to limited success in engineering abiotic stress tolerance in crops. This is because there needs to be a deeper understanding in how to combine resistances to a range of stresses with growth and productivity. The natural variation and genomic resources of Arabidopsis thaliana (Arabidopsis) is a great asset to understand the mechanisms of multiple stress tolerances...

The organellar two-pore channel (TPC) functions as a homodimer, in which each subunit contains two homologous Shaker-like six-transmembrane (6-TM)-domain repeats. TPCs belong to the voltage-gated ion channel superfamily and are ubiquitously expressed in animals and plants. Mammalian TPC1 and TPC2 are localized at the endolysosomal membrane, and have critical roles in regulating the physiological functions of these acidic organelles. Here we present electron cryo-microscopy structures of mouse TPC1 (MmTPC1)-a voltage-dependent, phosphatidylinositol 3,5-bisphosphate (PtdIns(3,5)P2 )-activated Na+ -selective channel-in both the apo closed state and ligand-bound open state...

Owing to their tremendous diversity and plasticity, immune cells exert multifaceted functions in tumor-bearing hosts, ranging from anti-tumor to pro-tumor activities. Tumor immune landscapes differ greatly between and within cancer types. Emerging evidence suggests that genetic aberrations in cancer cells dictate the immune contexture of tumors. Here, we review the current understanding of the mechanisms whereby common drivers of tumorigenesis modulate the tumor immune milieu. We discuss these findings in the context of clinical observations and examine how cancer-cell-intrinsic properties can be exploited to maximize the benefit of immunomodulatory therapies...

Optical methods of interrogating neural circuits have emerged as powerful tools for understanding how the brain drives behaviors. Optogenetic proteins are widely used to control neuronal activity, while genetically encoded fluorescent reporters are used to monitor activity. These proteins are often expressed by injecting viruses, which frequently leads to inconsistent experiments due to misalignment of expression and optical components. Here, we describe how silk fibroin films simplify optogenetic experiments by providing targeted delivery of viruses...

Picornaviruses have evolved to hijack host cellular machinery, including the autophagic pathway. However, the mechanisms remain largely unclear. We use coxsackievirus B3 (CVB3) as a model organism to explore the possible role of picornavirus subversion of the autophagic pathway in viral infection. Our in vivo and in vitro experiments demonstrate that CVB3 infection causes a significant, albeit incomplete, inhibition of autophagic flux by limiting the fusion of autophagosomes with lysosomes and/or late endosomes...

The high storage capacity of the episodic memory system relies on distinct representations for events that are separated in time and space. The spatial component of these computations includes the formation of independent maps by hippocampal place cells across environments, referred to as global remapping. Such remapping is thought to emerge by the switching of input patterns from specialized spatially selective cells in medial entorhinal cortex (mEC), such as grid and border cells. Although it has been shown that acute manipulations of mEC firing patterns are sufficient for inducing hippocampal remapping, it remains unknown whether specialized spatial mEC inputs are necessary for the reorganization of hippocampal spatial representations...

OBJECTIVE: To know the Brazilian scientific production of the last ten years (2007 to 2016) about people who experience street situations under the health gaze. METHOD: Integrative literature review using the descriptors: street people, health policy and public health. We analyzed 21 articles available in the Virtual Health Library. RESULTS: Four categories of analysis emerged. There was an increase in the frequency of published work on the subject, showing that the experience of living on the street makes people vulnerable to various diseases and health problems and, in addition, increases the difficulties of access to health services...
