Four pivotal NIH-funded artificial pancreas research efforts begin
The first of several major research efforts to test and refine artificial pancreas systems is now underway. Four separate projects, funded by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), are designed to be the potential last steps between testing the fully automated devices and requesting regulatory approval for permanent use. A successful artificial pancreas would be a life-changing advance for many people with type 1 diabetes. NIDDK is part of the National Institutes of Health.

NIH-sponsored expert panel issues clinical guidelines to prevent peanut allergy
An expert panel sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, issued clinical guidelines today to aid health care providers in early introduction of peanut-containing foods to infants to prevent the development of peanut allergy.

NIH awards aim to understand molecular changes during physical activity
The National Institutes of Health Common Fund announced today the first awards for the Molecular Transducers of Physical Activity in Humans Program, which will allow researchers to develop a comprehensive map of the molecular changes that occur in response to physical activity.

Medicare finalizes substantial improvements that focus on primary care, mental health, and diabetes prevention
Today, the Centers for Medicare & Medicaid Services (CMS) finalized the 2017 Physician Fee Schedule final rule that recognizes the importance of primary care by improving payment for chronic care management and behavioral health. The rule also finalizes many of the policies to expand the Diabetes Prevention Program model test to eligible Medicare beneficiaries, the Medicare Diabetes Prevention Program (MDPP) expanded model, starting January 1, 2018.

This National Diabetes Month, connect with your community for better health
For many millions of Americans, diabetes is a lifelong burden. But it does not have to be a lifelong barrier to better health. This National Diabetes Month, the National Institutes of Health encourages people with diabetes and those who care for them to find the support they need, and for all people to gain understanding and offer support to those with this challenging disease.

NIH researchers unveil new wound-healing role for protein-folding gene in mice
National Institutes of Health researchers have identified a novel role for a gene known as heat shock protein 60 (Hsp60), finding that it is critical in tissue regeneration and wound healing. The study found that topical treatment of an Hsp60-containing gel dramatically accelerates wound closure in a diabetic mouse model.

Weight loss leads to strong increase in appetite
Analysis of a trial that used the drug canagliflozin found that as people lost weight, their appetite increased proportionately, leading to consumption of more calories and weight loss plateau (leveling off). The findings provide the first measurement in people of how strongly appetite counters weight loss as part of the body’s feedback control system regulating weight. Results are currently available on BioRxiv (link is external) and will publish in Obesity during Obesity Week 2016.

NIH task force formed to develop first nutrition strategic plan
The National Institutes of Health Nutrition Research Task Force (NRTF) was established to coordinate and accelerate progress in nutrition research across the NIH and guide the development of the first NIH-wide strategic plan for nutrition research for the next 10 years.

Autonomic Testing in Women with Chronic Pelvic Pain.
[Medical College of Wisconsin; Case Western Reserve University] Researchers tested whether abnormal autonomic nervous system innervation of the bladder underlies IC (interstitial cystitis)/BPS (bladder pain syndrome) differently than other chronic pelvic pain. Some chronic pelvic pain types showed autonomic neuropathy and some show vagal withdrawal.

New medication shows promise against liver fibrosis in animal studies
A new drug developed by scientists at the National Institutes of Health limits the progression of liver fibrosis in mice, a hopeful advance against a condition for which there is no current treatment and that often leads to serious liver disease in people with chronic alcoholism and other common diseases.

Human islets contain four distinct subtypes of β cells.
[Oregon Health and Science University; University of Pennsylvania School of Medicine] Human pancreatic islets of Langerhans contain five distinct endocrine cell types, each producing a characteristic hormone. The dysfunction or loss of the insulin-producing β cells causes diabetes mellitus, a disease that harms millions. Until now, β cells were generally regarded as a single, homogenous cell population.

Antibiotics, birth mode, and diet shape microbiome maturation during early life.
[New York University Langone Medical Center] The intestinal “microbiota,” that is, the community of microbes inhabiting the human intestinal tract, undergoes many changes during the first 2 years of life. Bokulich et al. now show that this pattern of development is altered in children who are delivered by cesarean section, fed formula, or treated with antibiotics, compared to those babies who were born vaginally, breast-fed, or unexposed to antibiotics.

Acetate mediates a microbiome-brain-β-cell axis to promote metabolic syndrome.
[Yale University School of Medicine] Obesity, insulin resistance and the metabolic syndrome are associated with changes to the gut microbiota; however, the mechanism by which modifications to the gut microbiota might lead to these conditions is unknown. Here we show that increased production of acetate by an altered gut microbiota in rodents leads to activation of the parasympathetic nervous system, which, in turn, promotes increased glucose-stimulated insulin secretion, increased ghrelin secretion, hyperphagia, obesity and related sequelae.

Maternal diet quality in pregnancy and neonatal adiposity: the Healthy Start Study.
[Colorado School of Public Health; University of Colorado School of Medicine] Poor maternal diet in pregnancy can influence fetal growth and development. We tested the hypothesis that poor maternal diet quality during pregnancy would increase neonatal adiposity (percent fat mass [%FM]) at birth by increasing the FM component of neonatal body composition.

Genetic Coding Variant in GPR65, alters Lysosomal ph and Links Lysosomal Dysfunction with Colitis Risk.
[The Broad Institute of MIT and Harvard; Monash University] Although numerous polymorphisms have been associated with inflammatory bowel disease (IBD), identifying the function of these genetic factors has proved challenging. Here we identified a role for nine genes in IBD susceptibility loci in antibacterial autophagy and characterized a role for one of these genes, GPR65, in maintaining lysosome function.

Gene-microbiota interactions contribute to the pathogenesis of inflammatory bowel disease.
[California Institute of Technology] Inflammatory bowel disease (IBD) is associated with risk variants in the human genome and dysbiosis of the gut microbiome, though unifying principles for these findings remain largely undescribed. The human commensal Bacteroides fragilis delivers immunomodulatory molecules to immune cells via secretion of outer membrane vesicles (OMVs).

Generation of stem cell-derived β-cells from patients with type 1 diabetes.
[Washington University School of Medicine; Harvard University; Case Western Reserve University School of Medicine] We recently reported the scalable in vitro production of functional stem cell-derived β-cells (SC-β cells). Here we extend this approach to generate the first SC-β cells from type 1 diabetic patients (T1D). β-cells are destroyed during T1D disease progression, making it difficult to extensively study them in the past.

Persistent metabolic adaptation 6 years after "The Biggest Loser" competition.
[National Institute of Diabetes and Digestive and Kidney Diseases] Researchers measured long-term changes in resting metabolic rate (RMR) and body composition in participants of “The Biggest Loser” competition. Body composition was measured by dual energy X-ray absorptiometry, and RMR was determined by indirect calorimetry at baseline, at the end of the 30-week competition and 6 years later.

ZP2 peptide beads select human sperm in vitro, decoy mouse sperm in vivo, and provide reversible contraception.
[National Institute of Diabetes and Digestive and Kidney Diseases; University of Murcia, Murcia, Spain] The zona pellucida, a matrix that surrounds ovulated eggs, is the site of sperm recognition and binding, which precede sperm penetration and fertilization. Avella et al. identified a peptide from the zona pellucida called ZP2, which the authors attached to agarose beads to facilitate infertility treatment or, conversely, contraception.
