Type 2 Diabetes diagnosis at age 30 may cut life expectancy by up to 14 years

An individual diagnosed with type 2 diabetes at age 30 years could see their life expectancy fall by as much as 14 years, warns an international team of researchers in their findings, published in The Lancet Diabetes & Endocrinology. Even those diagnosed at age 50 years may face up to a six-year reduction in life expectancy.

For the study, researchers from the University of Cambridge and the University of Glasgow analyzed data from two major international studies, the Emerging Risk Factors Collaboration and UK Biobank, encompassing a total of 1.5 million individuals.

Romantic Relationships may hamper Sleep Patterns, finds study

A recent study conducted among Chinese adolescents has found that initiating and ending romantic relationships can contribute to sleep issues, particularly in younger girls, emphasizing the need for education on healthy romantic relationships to ensure sound sleep in early adolescence.

The research involved surveying 7,072 Chinese adolescents in November-December 2015 and then again one year later. Adolescents were asked about their romantic experiences, including starting a romantic relationship (SRR) and experiencing romantic breakups. The survey also assessed various factors such as sleep duration, insomnia symptoms, depressive symptoms, substance use, and demographics.

Early Metformin treatment in gestational diabetes shows mixed results in clinical trial

A recent double-blind, placebo-controlled clinical trial conducted in Ireland has shown that early initiation of metformin during gestation did not significantly reduce the need for insulin treatment or improve fasting blood sugar levels in pregnant individuals with gestational diabetes.

The trial published in JAMA involved 510 participants (comprising 535 pregnancies) diagnosed with gestational diabetes based on World Health Organization 2013 criteria. These individuals were randomly assigned to receive either metformin (up to 2500 mg daily) or a placebo in addition to their usual prenatal care.
