The Role of Extracellular Vesicles in β-Cell Function and Viability: A Scoping Review.

Extracellular vesicles (EVs) released by cells throughout the body have been implicated in diabetes pathogenesis. Understanding the role of EVs in regulation of β-cell function and viability may provide insights into diabetes etiology and may lead to the development of more effective screening and diagnostic tools to detect diabetes earlier and prevent disease progression. This review was conducted to determine what is known from the literature about the effect of EV crosstalk on pancreatic β-cell function and viability in the pathogenesis of diabetes mellitus, to perform a gap analysis for future research directions, and to discuss implications of available evidence for diabetes care.

Preclinical model systems of ryanodine receptor 1-related myopathies and malignant hyperthermia: a comprehensive scoping review of works published 1990-2019.

Background: Pathogenic variations in the gene encoding the skeletal muscle ryanodine receptor (RyR1) are associated with malignant hyperthermia (MH) susceptibility, a life-threatening hypermetabolic condition and RYR1-related myopathies (RYR1-RM), a spectrum of rare neuromuscular disorders. In RYR1-RM, intracellular calcium dysregulation, post-translational modifications, and decreased protein expression lead to a heterogenous clinical presentation including proximal muscle weakness, contractures, scoliosis, respiratory insufficiency, and ophthalmoplegia. Preclinical model systems of RYR1-RM and MH have been developed to better understand underlying pathomechanisms and test potential therapeutics.

The Effects of Obesity on Outcome in Preclinical Animal Models of Infection and Sepsis: A Systematic Review and Meta-Analysis.

Background: Clinical studies suggest obesity paradoxically increases survival during bacterial infection and sepsis but decreases it with influenza, but these studies are observational. By contrast, animal studies of obesity in infection can prospectively compare obese nonobese controls. We performed a systematic review and meta-analysis of animal investigations to further examine obesity's survival effect in infection and sepsis.

Statins for Smith-Lemli-Opitz syndrome.

This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: 1. To evaluate the efficacy of statin therapy in reducing the frequency or severity of the neurobehavioral abnormalities seen in people with SLOS (e.

Effect of restricted dissolved oxygen on expression of Clostridium difficile toxin A subunit from E. coli.

The repeating unit of the C. difficile Toxin A (rARU, also known as CROPS [combined repetitive oligopeptides]) C-terminal region, was shown to elicit protective immunity against C. difficile and is under consideration as a possible vaccine against this pathogen.

Methods: ICSN hosts a biennial scientific meeting and scientific working groups.

Advancing the Health of Populations Across the Life Course: 50 Years of Discoveries in the Division of Intramural Population Health Research.

In 2017, the Division of Intramural Population Health Research (DIPHR), within the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), reached a significant milestone: 50 years in existence. DIPHR celebrated this anniversary with a scientific program that reviewed past accomplishments and reflected on future directions in support of promoting the health of populations across the life course. Extending from the scientific program, the impetus of this article is to contribute to archiving and consolidating the legacy of intramural population health research at NICHD over the past 50 years.

Characteristics and Challenges of Dietary Supplement Databases Derived from Label Information.

Launched in 2008, the Dietary Supplement Label Database (DSLD) permits the search of any term that appears anywhere on product labels. Since then, the database's search and download features have been periodically improved to enhance use for researchers and consumers. In this review, we describe how to customize searches and identify products and ingredients of interest to users in the DSLD, and provide the limitations of working with information derived from dietary supplement product labels.

Disaster Medicine: A Comprehensive Review of the Literature From 2016.

Objective: The Society of Academic Emergency Medicine Disaster Medicine Interest Group, the Office of the Assistant Secretary for Preparedness and Response - Technical Resources, Assistance Center, and Information Exchange (ASPR TRACIE) team, and the National Institutes of Health Library searched disaster medicine peer-reviewed and gray literature to identify, review, and disseminate the most important new research in this field for academics and practitioners.

Methods: MEDLINE/PubMed and Scopus databases were searched with key words. Additional gray literature and focused hand search were performed.

Chemical, Biological, Radiological, Nuclear, and Explosive (CBRNE) Science and the CBRNE Science Medical Operations Science Support Expert (CMOSSE).

A national need is to prepare for and respond to accidental or intentional disasters categorized as chemical, biological, radiological, nuclear, or explosive (CBRNE). These incidents require specific subject-matter expertise, yet have commonalities. We identify 7 core elements comprising CBRNE science that require integration for effective preparedness planning and public health and medical response and recovery.

SMFM Special Statement: State of the science on multifetal gestations: unique considerations and importance.

We sought to review the state of the science for research on multiple gestations. A literature search was performed with the use of PubMed for studies to quantify the representation of multiple gestations for a sample period (2012-2016) that were limited to phase III and IV randomized controlled trials, that were written in English, and that addressed at least 1 of 4 major pregnancy complications: fetal growth restriction or small-for-gestational-age fetus, gestational diabetes mellitus, preeclampsia, and preterm delivery. Of the 226 studies that are included in the analysis, multiple pregnancies were most represented in studies of preterm delivery: 17% of trials recruited both singleton and multiple pregnancies; another 18% of trials recruited only multiple pregnancies.

Infant milk-feeding practices and diabetes outcomes in offspring: a systematic review.

Background: During the Pregnancy and Birth to 24 Months Project, the US Departments of Agriculture and Health and Human Services initiated a review of evidence on diet and health in these populations.
