Within three years of a dangerously low blood sugar episode, one-third of those in the study died.
A recent study published in Environmental Health found that women of childbearing age in the US are eating more fish while having lower blood mercury concentrations. The research indicates that tailored fish consumption advisories based on region and ethnic group would help women eat healthier and monitor their mercury intake better.
A new study found that a diabetes drug called amylin improved learning and memory function in AD patients and reduced AD pathology in their brains. The findings suggest a potential blood test for AD using pramlintide.
A University at Buffalo researcher says there is insufficient evidence to support dietary recommendations for children with elevated blood lead levels. The CDC's guidelines suggest eating iron-rich foods, calcium, and vitamin C, but the author argues that this approach lacks scientific backing.
Researchers recommend that doctors exclude common liver issues before testing for rare conditions. Directed testing means ordering tests for the most common causes of sudden severe liver issues first, followed by tests for rare, dangerous autoimmune or genetic disorders that attack livers.

The university will explore a 'molecular diversity' of potential glucose-responsive insulin analogs to develop rapid-acting, glucose-responsive insulins that become active when blood sugar is high and inactive when low. The goal is to mitigate the risk of blood sugar levels being too high or too low for patients with type 1 diabetes.

A recent study found that newborns with low vitamin D levels were more likely to develop multiple sclerosis (MS) later in life. The study analyzed data from over 500 Danish children born between 1981 and 2012, comparing their vitamin D levels to those of similar children without MS.
A new study by MassGeneral Hospital for Children-led team found that nearly one in five children with celiac disease sustained persistent intestinal damage despite a gluten-free diet. The study suggests that current guidelines need to be revised to include more aggressive monitoring of mucosal healing in all patients, not just adults.
The US blood system is under pressure due to reduced demand, technological advancements, and emerging pathogens. To address these challenges, researchers recommend targeted government oversight, comprehensive data collection, and subsidy support for blood centers to maintain surge capacity.

Researchers found a significant association between elevated blood sugar in early pregnancy and the risk of delivering a baby with congenital heart disease. The study, which analyzed data from 19,107 pregnant women, suggests that blood sugar levels may be a better predictor of this risk than current oral glucose tolerance tests.
Researchers found a positive correlation between omega-3 fatty acid levels and lower systolic and diastolic blood pressures. Eating diets rich in omega-3 foods could be a strategy to prevent high blood pressure.
A new study finds that smokers are at nearly twice the risk of developing an abdominal aortic aneurysm compared to non-smokers. Quitting smoking can reduce this risk by substantial amounts, particularly among current and former female smokers.
Higher vitamin D levels in blood are associated with better overall survival in breast cancer patients, according to a new study published in JAMA Oncology. The research found stronger associations between higher vitamin D levels and improved survival in premenopausal women.
