Mismatch hypothesis supports link of obesity and disease to dietary changes

A study by Princeton University and Mpala Research Center, in Kenya, has found evidence for the ‘mismatch’ hypothesis when they found that obesity, diabetes and cardiovascular illnesses increased among whose diet changed from animal-based to carbohydrate-based. The mismatch hypothesis argues that our bodies have evolved and adapted to digest the foods that our ancestors ate and that human bodies will struggle and largely fail to metabolise a radically new set of foods.

Pre-bariatric surgery aerobic exercise decreases hospital stay

Undertaking aerobic exercise prior to bariatric surgery in addition to standard medical care decreased the length of hospital stay in patients receiving bariatric surgery, compared to standard medical care alone, according to the outcomes of a small pilot trial by researchers from University of Virginia, Charlottesville, VA. The outcomes were featured in the paper, ‘Pre-operative aerobic exercise on metabolic health and surgical outcomes in patients receiving bariatric surgery: A pilot trial’, published in PLOS One.

Increase access to bariatric surgery for PCOS treatment

Access to bariatric surgery should be increased as part of the main treatment considerations in women with obesity and polycystic ovarian syndrome (PCOS). The paper, ‘A Review of the Impact of Bariatric Surgery in Women With Polycystic Ovary Syndrome’, published in Cureus, led by California Institute of Behavioral Neurosciences & Psychology, Fairfield in the US, also recommends that additional research with better study designs are required in the future to investigate the relationship between PCOS and bariatric surgery.

Vietnamese Americans without obesity 60% more likely to have diabetes

Vietnamese-American adults who did not have obesity were 60% more likely to have diabetes than those without obesity, non-Hispanic, White Americans, after accounting for age, sex, sociodemographic factors, smoking history and exercise level. Overall, only 9% of Vietnamese Americans with diabetes in the study had obesity. In comparison, half of all non-Hispanic White Americans with diabetes had obesity.

Abnormalities in laminin expression associated with Hirschsprung disease

Researchers from Le Bonheur Children's Hospital and the University of Tennessee Health Science Center who are trying to determine the mechanisms underlying abnormal development of the enteric nervous system in Hirschsprung disease, have reported delineating interactions between migrating neural crest cells and the extracellular matrix in a model of Hirschsprung disease using a variety of in vitro and in vivo approaches.

Obesity rates among Irish primary school children deceasing

According to the latest The Childhood Obesity Surveillance Initiative (COSI) in the Republic of Ireland (COSI) survey - carried out as part of the World Health Organization and European Union's effort to measure weight trends in young children - obesity rates in primary school children across Ireland are decreasing. The prevalence of obesity in children aged six to ten has continued to go down year on year.
