#1
David Sweet, Julian Marsden, Kendall Ho, Christina Krause, James A Russell
Many emergency departments have implemented sepsis protocols since the 2001 publication of results from the early goal-directed therapy trial, which showed early targeted resuscitation lowers mortality. As part of an attempt to improve clinical and operational outcomes for emergency departments across British Columbia, we reviewed sepsis management literature and considered sepsis protocol implementation in the province’s emergency departments. During the literature review we found that many observational studies confirmed an association between implementation of emergency sepsis protocols and decreased mortality...

We retrospectively collected cases of surgically proven extradigital glomus tumor (EDGT) and reviewed their demographic, clinical, and sonography features. A total of 18 single, subcutaneous EDGTs were gathered. All but one were located in the extremities. EDGTs typically appear as a small, hypoechoic, homogeneous, or slightly inhomogeneous, well-delimited nodule, disposed horizontally and painful under probe pressure. Intranodular vascularization is always present. Feeding artery and efferent vein are typical but inconstant findings...

INTRODUCTION: Helicobacter pylori infection is very prevalent worldwide and is associated with the progression of the gastric carcinogenesis cascade, being one of the main risk factors for the development of gastric carcinoma. Several factors are determinant for the infection and for the development of gastric disease, including environmental factors, host genetic factors and virulence factors of the bacteria. MATERIAL AND METHODS: In this review, we present an overview of the current knowledge on the determinants of the infection and on the recently described molecular mechanisms of Helicobacter pylori adhesion to the gastric mucosa, as well as its possible future therapeutic application...

INTRODUCTION: Polycystic ovary syndrome is the most frequent cause of anovulatory infertility and management involves a multistep approach. Laparoscopic ovarian diathermy is accepted as a second-line treatment of patients who failed to respond to clomiphene citrate. The aims of this study were to determine the efficacy of this technique at short and long-term and to perform an analysis of predictive factors of spontaneous pregnancy. MATERIAL AND METHODS: This retrospective study involved 76 women who underwent laparoscopic ovarian diathermy between 2004 and 2013 in a university hospital...

INTRODUCTION: Multiple sclerosis is most often diagnosed among young adults but less frequently it may present during childhood or adolescence. In Portugal, there has been only one previous single-center, pediatric multiple sclerosis study. The main objective was the evaluation of the demographic, clinical, laboratorial and neuroradiological characteristics of patients with pediatric-onset multiple sclerosis in Portugal. The secondary objectives were to compare the characteristics of childhood-onset multiple sclerosis and adolescent-onset multiple sclerosis and to characterize the treatments prescribed...

Some of the main causes of mortality and morbidity among the developed countries - such as the cardiovascular, neurological and oncologic diseases - are deeply associated with modifiable risk factors. Primordial/primary prevention strategies that alter our environment can have an impact on these risk factors. The authors of this Cochrane systematic review sought evidence from randomized controlled trials to study the effect of the size of portions, packages, dishes and cups, as well as their respective formats, on the consumption and selection of food, alcoholic and non-alcoholic beverages and tobacco products...

Se Young Choi, Chang Gyo Yoon
We sought to describe the incidence rate of the urologic disease in the Korean military by reviewing diagnoses made in active duty soldiers from 2008 to 2013. A total of 72,248 first visits were generated in the Defense Medical Statistics Information System (DMSIS) with its gradually increasing trend over 6 years. A sharp increase of first visit was observed after implementation of the regular health check-up for all conscripted soldiers since 2013. Urolithiasis, prostatitis, epididymoorchitis, urethritis, and varicocele were prevalent...

Subclinical hypothyroidism (SCH) is a common problem in pediatric population, and the natural history of SCH varies depending on its etiology. Whether Hashimoto's thyroiditis (HT) negatively affects the natural course of SCH was investigated in pediatric patients without concomitant diseases. Predictors for levothyroxine medication were also evaluated. Medical records of 109 children with SCH (91 girls, 5?18 years) diagnosed between 2005 and 2014 were retrospectively reviewed. Patients were classified into HT (n = 37) and isolated non-autoimmune hyperthyrotropinemia (iso-NAHT, n = 72)...

Adding either macrolide or fluoroquinolone (FQ) to β-lactam has been recommended for patients with severe community-acquired pneumonia (CAP). However, due to the limited evidence available, there is a question as to the superiority of the two combination therapies. The MEDLINE, EMBASE, Cochrane Central Register, Scopus, and Web of Science databases were searched for systematic review and meta-analysis. A total of eight trials were analyzed. The total number of patients in the β-lactam plus macrolide (BL-M) and β-lactam plus fluoroquinolone (BL-F) groups was 2,273 and 1,600, respectively...

In Sub Kim, Won Min Jo
Although anticoagulation therapy is the primary treatment for deep vein thrombosis (DVT), it has not been associated with the rapid recanalization of the venous occlusion. Moreover, it is associated with long-term disability due to post-thrombotic syndrome (PTS). In contrast, pharmacomechanical endovascular intervention (PMI) results in more rapid clinical improvement in DVT patients, but there are few reports on its long-term outcomes. This retrospective study evaluated the clinical effectiveness of PMI compared to conventional anticoagulation therapy (ACA) for acute and subacute iliofemoral DVT...

In patients with colorectal cancer (CRC), the BRAF V600E mutation has been reported to be associated with several clinicopathological features and poor survival. However, the prognostic implications of BRAF V600E mutation and the associated clinicopathological characteristics in CRCs remain controversial. Therefore, we reviewed various clinicopathological features, including BRAF status, in 349 primary CRCs and analyzed the relationship between BRAF status and various clinicopathological factors, including overall survival...

BACKGROUND: Chronic venous insufficiency (CVI) is a common disease that causes discomfort and impairs the quality of life of affected persons. Treatments such as physical exercise that aim to increase the movement of the ankle joint and strengthen the muscle pump in the calf of the leg may be useful to reduce the symptoms of CVI. OBJECTIVES: To assess and summarise the existing clinical evidence on the efficacy and safety of physical exercise programmes for the treatment of individuals with non-ulcerated CVI...

Caitlin Collins, Xavier Didelot
Following recent developments in DNA sequencing technology, it is now possible to sequence hundreds of whole genomes from bacterial isolates at relatively low cost. Analyzing this growing wealth of genomic data in terms of ancestral relationships can reveal many interesting aspects of the evolution, ecology, and epidemiology of bacterial pathogens. However, reconstructing the ancestry of a sample of bacteria remains challenging, especially for the majority of species where recombination is frequent. Here, we review and describe the computational techniques currently available to infer ancestral relationships, including phylogenetic methods that either ignore or account for the effect of recombination, as well as model-based and model-free phylogeny-independent approaches...

Helicobacter pylori (H. pylori) is a highly successful bacterial pathogen, which colonizes the stomach of more than half of the world's population. To colonize and survive in such an acidic and inhospitable niche, H. pylori cells have evolved complex mechanisms to acquire nutrients from human hosts, including iron, an essential nutrient for both the pathogens and host cells. However, human cells also utilize diverse strategies in withholding of irons to prevent the bacterial outgrowth. The competition for iron is the central battlefield between pathogen and host...

An important aspect of protein functionality is the formation of specific complexes with other proteins, which are involved in the majority of biological processes. The functional characterization of such interactions at molecular level is necessary, not only to understand biological and pathological phenomena but also to design improved, or even new interfaces, or to develop new therapeutic approaches. X-ray crystallography and NMR spectroscopy have increased the number of 3D protein complex structures deposited in the Protein Data Bank (PDB)...

Jie Li, Patrice Koehl
Computational protein sequence design is the rational design based on computer simulation of new protein molecules to fold to target three-dimensional structures, with the ultimate goal of designing novel functions. It requires a good understanding of the thermodynamic equilibrium properties of the protein of interest. Here, we consider the contribution of the solvent to the stability of the protein. We describe implicit solvent models, focusing on approximations of their nonpolar components using geometric potentials...

One main challenge in Computational Protein Design (CPD) lies in the exploration of the amino-acid sequence space, while considering, to some extent, side chain flexibility. The exorbitant size of the search space urges for the development of efficient exact deterministic search methods enabling identification of low-energy sequence-conformation models, corresponding either to the global minimum energy conformation (GMEC) or an ensemble of guaranteed near-optimal solutions. In contrast to stochastic local search methods that are not guaranteed to find the GMEC, exact deterministic approaches always identify the GMEC and prove its optimality in finite but exponential worst-case time...

Alzheimer's disease (AD) is the most common cause of dementia in elderly people. Because of the lack of effective treatments for this illness, research focused on identifying compounds that restore cognition and functional impairments in patients with AD is a very active field. Since its discovery in 1993, the serotonin 5-HT6 receptor has received increasing attention, and a growing number of studies supported 5-HT6 receptor antagonism as a target for improving cognitive dysfunction in AD. This article reviews the rationale behind investigations into the targeting of 5-HT6 receptors as a symptomatic treatment for cognitive and/or behavioral symptoms of AD...
