Importance: Concerns exist about the current quality of undergraduate medical education and its effect on students' well-being. Objective: To identify best practices for undergraduate medical education learning environment interventions that are associated with improved emotional well-being of students. Data Sources: Learning environment interventions were identified by searching the biomedical electronic databases Ovid MEDLINE, EMBASE, the Cochrane Library, and ERIC from database inception dates to October 2016...

OBJECTIVE: We performed a systematic review and meta-analysis to examine the accuracy of bedside ultrasound for confirmation of central venous catheter position and exclusion of pneumothorax compared with chest radiography. DATA SOURCES: PubMed, Embase, Cochrane Central Register of Controlled Trials, reference lists, conference proceedings and ClinicalTrials.gov. STUDY SELECTION: Articles and abstracts describing the diagnostic accuracy of bedside ultrasound compared with chest radiography for confirmation of central venous catheters in sufficient detail to reconstruct 2 × 2 contingency tables were reviewed...

BACKGROUND: Several randomized controlled trials (RCTs) compared induction of labour with expectant management in non-diabetic women with suspected fetal macrosomia. OBJECTIVE: To evaluate the effects of labour induction for suspected fetal macrosomia. SEARCH STRATEGY: Literature search in electronic databases. SELECTION CRITERIA: We included all RCTs of suspected fetal macrosomia comparing labour induction with expectant management in term pregnancy...

Density functional theory calculations have been used to elucidate the mechanism of the addition reaction of acetaldehyde to the positively charged hydrogenated silicene (H-silicene). We find that the positively charged H-silicene plane could be partially restructured to form a vacant Si site, enabling a further nucleophilic addition reaction. After acetaldehyde molecule attached to the H-silicene plane, two competing pathways are involved in hydrogen abstraction process: a random reaction mechanism and a chain reaction mechanism...

Rebecca V Harris, Andrew Pennington, Margaret Whitehead
BACKGROUND: In many countries, those with lower socioeconomic status are disproportionately affected by poor oral health. This can be attributed, at least in part, to differences in preventive dental visiting. While several theories have been applied to the area, they generally fail to capture the recursive nature of dental visiting behaviour, and fall short of informing the design of complex interventions to tackle inequalities. OBJECTIVE: To undertake a systematic review and synthesis of theory in order to provide an overview of the pathways which bring about socioeconomic inequalities in early dental visiting, and identify possible intervention points...

In the gas phase, protein ions can adopt a broad range of structures, which have been investigated extensively in the past using ion mobility-mass spectrometry (IM-MS)-based methods. Compact ions with low number of charges undergo a Coulomb-driven transition to partially folded species when the charge increases, and finally form extended structures with presumably little or no defined structure when the charge state is high. However, with respect to the secondary structure, IM-MS methods are essentially blind...

Oncogenic BRaf V600E mutation is involved in the development, invasion and metastasis of colon cancer. Selective inhibition of BRaf(V600E) mutant has been recognized as a therapeutic strategy for the cancer. Here, we carried out atomistic molecular dynamics (MD) simulations to characterize the structural basis, energetic property, and dynamics behavior of conformational change in BRaf activation loop upon the mutation. It is found that V600E mutation destabilizes inactive DFG-out conformation of activation loop and promotes its conversion to the active DFG-in conformation, thus conferring constitutive activity for BRaf kinase...

BACKGROUND: Seroepidemiologic studies indicate a high prevalence of herpes simplex virus (HSV) infection. This infection leads to ophthalmic, dermatologic, oral, neurologic, vaginal and cervical problems. Different studies have been carried out to estimate the HSV seroprevalence in Iran. Combining the results of these studies would be useful for health policy-making. OBJECTIVE: This study aims to estimate the pooled prevalence of HSV infection using meta-analysis...

#16
Natalia Y Bilenko, Jack L Gallant
In this article we introduce Pyrcca, an open-source Python package for performing canonical correlation analysis (CCA). CCA is a multivariate analysis method for identifying relationships between sets of variables. Pyrcca supports CCA with or without regularization, and with or without linear, polynomial, or Gaussian kernelization. We first use an abstract example to describe Pyrcca functionality. We then demonstrate how Pyrcca can be used to analyze neuroimaging data. Specifically, we use Pyrcca to implement cross-subject comparison in a natural movie functional magnetic resonance imaging (fMRI) experiment by finding a data-driven set of functional response patterns that are similar across individuals...

AIM: To perform meta-analysis of the use of Endocuff during average risk screening colonoscopy. METHODS: Scopus, Cochrane databases, MEDLINE/PubMed, and CINAHL were searched in April 2016. Abstracts from Digestive Disease Week, United European Gastroenterology, and the American College of Gastroenterology meeting were also searched from 2004-2015. Studies comparing EC-assisted colonoscopy (EAC) to standard colonoscopy, for any indication, were included in the analysis...

REVIEW
Henrik Johansson, Roland Andersson, Monika Bauden, Sarah Hammes, Stefan Holdenrieder, Daniel Ansari
Novel treatment modalities are necessary for pancreatic cancer. Immunotherapy with immune checkpoint inhibition has shown effect in other solid tumors, and could have a place in pancreatic cancer treatment. Most available clinical studies on immune checkpoint inhibitors for pancreatic cancer are not yet completed and are still recruiting patients. Among the completed trials, there have been findings of a preliminary nature such as delayed disease progression and enhanced overall survival after treatment with immune checkpoint inhibitors in mono- or combination therapy...

BACKGROUND: Strokes are often preceded by a transient ischaemic attack (TIA) or 'minor' stroke. The immediate period after a TIA/minor stroke is a crucial time to initiate secondary prevention. However, the optimal approach to prevention, including non-pharmacological measures, after TIA is not clear. AIM: To systematically review evidence about the effectiveness of delivering secondary prevention, with lifestyle interventions, in comprehensive rehabilitation programmes, initiated within 90 days of a TIA/minor stroke...

OBJECTIVE:  To assess the comparative efficacy and safety of candidate agents (low and high dose aspirin, non-aspirin non-steroidal anti-inflammatory drugs (NSAIDs), calcium, vitamin D, folic acid, alone or in combination) for prevention of advanced metachronous neoplasia (that is, occurring at different times after resection of initial neoplasia) in individuals with previous colorectal neoplasia, through a systematic review and network meta-analysis. DATA SOURCES:  Medline, Embase, Web of Science, from inception to 15 October 2015; clinical trial registries...
