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.
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.
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.
Researchers at Ben-Gurion University of the Negev (BGU) have discovered a neural subnetwork of connected regions between the brain and gastric basal electric frequency that correlates with future weight loss based on connectivity patterns.
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.
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.
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.
Too much abdominal fat amongst the Mexican Americans population predicts the beginning of atherosclerosis, but researchers at McGovern Medical School at the University of Texas Health Science Center at Houston, TX, report that this is only true for those who were born in the US.
People who have had bariatric surgery live three years longer, on average, than those given conventional treatment for their obesity, a University of Gothenburg study has reported. Compared with the general population, however, both groups' excess mortality is higher.
The probability that a person with obesity will develop severe COVID-19 is high regardless of age, sex, ethnicity and the presence of co-morbidities such as diabetes, high blood pressure, and heart or lung disease, according to a Brazilian study.
