BACKGROUND: Since prehistory to present times and despite a rough combat against it, malaria remains a concern for human beings. While evolutions of science and technology through times allowed for some infectious diseases eradication in the 20th century, malaria resists. OBJECTIVES: This review aims at assessing how Internet and web technologies are used in fighting malaria. Precisely, how do malaria fighting actors profit from these developments, how do they deal with ensuing phenomena, such as the increase of data volume, and did these technologies bring new opportunities for fighting malaria? METHODS: Eleven web platforms linked to spatio-temporal malaria information are reviewed, focusing on data, metadata, web services and categories of users...

BACKGROUND: Although the incidence of leaks after Roux-en-Y gastric bypass (RYGB) significantly decreased over time, their detection still remains challenging. OBJECTIVE: This study aimed to determine the usefulness of drain amylase levels to detect leaks after RYGB. METHODS: This is a population-based study which enrolled 170 individuals who underwent RYGB. Drain amylase levels were determined on the first and fourth postoperative days. Two thresholds were evaluated: three times higher than the serum levels (parameter I) and higher than 250 IU/L (parameter II)...

BACKGROUND: Even if the jejunoileal bypass has been definitely abandoned due to the high rate of hepatic complications, cases of liver injury after the new bariatric procedures are still reported. We aimed to review the available literature concerning liver damage associated with the older and newer types of bariatric surgeries. METHODS: An extensive literature search of MEDLINE was performed using different combinations of the following terms: "bariatric surgery OR biliopancreatic diversion OR jejunoileal bypass OR roux-en-y gastric bypass OR vertical banded gastroplasty OR laparoscopic adjustable gastric banding" AND "hepatic/liver damage OR hepatic/liver impairment OR hepatic/liver failure"...

The aim of this study is to highlight the robustness and potentials of the anaerobic baffled reactor (ABR) configuration on keeping the microbial richness and diversity after starvation period of 7 days. The module at steady state operating conditions provided an average volumetric hydrogen production (VHP) of 0.2±0.08 and 0.423±0.5 l/d in the 1st and last compartment (C4). The VHP was gradually decreased from 0.2 to 0.003 l/d and from 0.423 to 0.1 l/d in compartments (C1 and C4) respectively during feed less period...

BACKGROUND: Management options for marginal ulcers (MU) vary from medical therapy to revision surgery. Medical therapy is often ineffective and revision surgery is associated with a high morbidity and possible recurrence. AIMS: To evaluate technical feasibility, efficacy, and safety of endoscopic management of MU by covering the ulcer bed using oversewing and/or deploying a fully covered self-expandable metallic stent (FCSEMS). METHODS: Medical records of consecutive patients who underwent endoscopic suturing and/or FCSEMS deployment for recalcitrant MU between August 2016 and June 2017 at a single academic center were reviewed...

BACKGROUND: In recent years, gastric bypass surgery has been found to have therapeutic potential for the treatment of type 2 diabetes (T2D). However, the difference between 2 bypass procedures, Roux-en-Y gastric bypass (RYGB) and another single anastomosis gastric bypass (SAGB), is not clear. OBJECTIVE: To evaluate the differences between SAGB and RYGB in the efficacy of T2D remission in obese patients. SETTING: Tertiary teaching hospital...

Bone turnover increases at the menopause and is associated with accelerated bone loss. However, it is not known to what extent there is an imbalance between the processes of bone resorption and bone formation, nor whether it is the rate of bone turnover or the bone balance that is most closely associated with the rate of bone loss. We studied 657 healthy women ages 20 to 79 from five European cities (the OPUS Study) and divided them into two premenopausal age groups, 20 to 29 (n = 129), 30 to 39 years (n = 183), and three postmenopausal groups 1 to 10 years (n = 91), 11 to 20 years (n = 131) and 21+ years since menopause (n = 123)...

BACKGROUND: Contemporary mortality after bariatric surgery is low and has been decreasing over the past two decades. Most studies have reported inpatient or 30-day mortality, which may not represent the true risk of bariatric surgery. The objective of this study was to examine 1-year mortality and factors predictive of 1-year mortality after contemporary laparoscopic bariatric surgery. STUDY DESIGN: Using the 2008-2012 Bariatric Outcomes Longitudinal Database (BOLD), data from 158,606 operations were analyzed, including 128,349 (80...

BACKGROUND: According to recent American Society for Metabolic and Bariatric Surgery estimates, sleeve gastrectomy (SG) is now the most commonly performed procedure in the United States (~53.8% of all bariatric procedures), followed by Roux-en-Y gastric bypass (RYGB; 23.1% of all procedures). OBJECTIVES: The objective of this study was to evaluate outcomes and safety of these 2 procedures in the first 30 days postoperatively using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program data registry...

The African fungal tree pathogen, Ceratocystis albifundus, undergoes uni-directional mating type switching, giving rise to either self-fertile or self-sterile progeny. Self-sterile isolates lack the MAT1-2-1 gene and have reduced fitness such as slower growth and reduced pathogenicity, relative to self-fertile isolates. While it has been hypothesized that there is a 1:1 ratio of self-fertile to self-sterile ascospore progeny in relatives of C. albifundus, some studies have reported a significant bias in this ratio...

Matrix-assisted laser/desorption ionization (MALDI) mass spectrometry imaging (MSI) is widely used as a unique tool to record the distribution of a large range of biomolecules in tissues. 2,6-Dihydroxyacetophenone (DHA) matrix has been shown to provide efficient ionization of lipids, especially gangliosides. The major drawback for DHA as it applies to MS imaging is that it sublimes under vacuum (low pressure) at the extended time necessary to complete both high spatial and mass resolution MSI studies of whole organs...

INTRODUCTION: Roux-en-Y gastric bypass and sleeve gastrectomy are the two most common bariatric surgery performed in the UK that result in comparable weight loss and remission of obesity-associated comorbidities. However, there is a paucity of studies examining the impact of these procedures on body composition, physical activity levels, sedentary behaviour, physical function and strength, dietary intake, health-related quality of life and costs. METHODS AND ANALYSIS: The BARI-LIFESTYLE observational study is a 1-year prospective, longitudinal cohort study within a real-world routine clinical care setting aiming to recruit 100 patients with severe obesity undergoing either primary Roux-en-Y gastric bypass or sleeve gastrectomy from two bariatric centres in London, UK...

BACKGROUND: Altered enteroendocrine hormone responses are widely believed to underlie the beneficial effects of bariatric surgery in type 2 diabetes. While elevated postprandial glucagon-like peptide-1 (GLP-1) is considered one of the mediators, increased postprandial glucagon levels have recently been implicated. OBJECTIVES: We investigated hormonal responses in lean patients after prophylactic total gastrectomy (PTG), as a model of Roux-en-Y gastric bypass without the confounding effects of obesity or massive weight loss...

OBJECTIVE: Rituximab (RTX) is an anti-CD20 monoclonal antibody that selectively depletes B-cell population. Thus, it presents a potential risk for the development of hypogammaglobulinemia and related infectious events. Our aim was to identify predictors of hypogammaglobulinemia in RA patients long-term treated with RTX. METHODS: Multicenter observational usual care study of patients with RA on RTX maintenance therapy (minimal exposition of 30 months). Serum protein electrophoresis was performed before each RTX infusion...

Although dense neighborhood built environments support increased physical activity and lower obesity, these features may also disturb sleep. Therefore, we sought to understand the association between the built environment and objectively measured sleep. From 2010 to 2013, we analyzed data from examination 5 of the Multi-Ethnic Study of Atherosclerosis, a diverse population from 6 US cities. We fit multilevel models that assessed the association between the built environment (Street Smart Walk Score, social engagement destinations, street intersections, and population density) and sleep duration or efficiency from 1-week wrist actigraphy in 1,889 individuals...

Axons of the corpus callosum (CC), the white matter tract that connects the left and right hemispheres of the brain, receive instruction from a number of chemoattractant and chemorepulsant cues during their initial navigation towards and across the midline. While it has long been known that the CC is malformed in the absence of Myristoylated alanine-rich C-kinase substrate (MARCKS), evidence for a direct role of MARCKS in axon navigation has been lacking. Here, we show that MARCKS is necessary for Netrin-1 (NTN1) signaling through the DCC receptor, which is critical for axon guidance decisions...
