Overgrowth of baby in the womb may begin weeks before women are tested for maternal diabetes

The excessive growth of a baby in the womb, a common complication of gestational diabetes, begins weeks before women are tested for the disease, according to new research being presented at this year's European Association for the Study of Diabetes (EASD) Annual Meeting in Barcelona, Spain (16-20 September).

Analysis of studies into alcohol consumption in people with type 2 diabetes suggests

An meta-analysis of studies presented at this year's Annual Meeting of the European Association for the Study of Diabetes in Barcelona, Spain (16-20 September) shows that recommendations to moderate alcohol consumption for people with type 2 diabetes (T2D) may need to be reviewed, since low-to-moderate consumption could have a positive effect on blood glucose and fat metabolism.

Meal type and size are the key factors affecting carb-counting in type 1 diabetes

Meal type and size are the most important factors influencing the accuracy of carb-counting for the control of blood sugar in type 1 diabetes, according to new research being presented at this year's European Association for the Study of Diabetes (EASD) Annual Meeting in Barcelona, Spain (16-20 September).

Short-term study suggests vegan diet can boost gut microbes related to body weight

New research presented at this year's Annual Meeting of the European Association for the Study of Diabetes (EASD) in Barcelona, Spain (16-20 Sept) suggests that a 16-week vegan diet can boost the gut microbes that are related to improvements in body weight, body composition and blood sugar control. The study is by Dr. Hana Kahleova, Physicians Committee for Responsible Medicine (PCRM), Washington, DC, USA, and colleagues.

Daily aspirin may benefit many patients without existing cardiovascular disease

The benefits of aspirin may outweigh the risks for many patients without known cardiovascular disease (CVD). Such patients could be identified by using a personalized benefit-harm analysis, which could inform discussions between doctors and patients. The findings are published in Annals of Internal Medicine.

Later puberty and later menopause associated with lower risk of type 2 diabetes in women

New research presented at this year's Annual Meeting of the European Association for the Study of Diabetes (EASD) in Barcelona, Spain (16-20 Sept) shows that use of the contraceptive pill and longer menstrual cycles are associated with a higher risk of developing type 2 diabetes (T2D), while later puberty and later menopause are associated with lower risk.

No difference in pain response between SBRT and conventional RT for patients with spinal metastases

A Phase III, NRG Oncology clinical trial that compared radiosurgery (SRS) or stereotactic body radiotherapy (SBRT) to the conventional radiotherapy (cEBRT) for patients with spinal metastases indicated that there was no statistically significant difference between the treatments for pain response, adverse events, FACT-G, BPI, and EQ-5D scores. These results were presented during the plenary session of the American Society of Radiation Oncology's (ASTRO) Annual Meeting in September 2019. The abstract was one of four abstracts chosen from over 3,000 submitted abstracts for the plenary session.

Nature documentaries increasingly talk about threats to nature, but still don't show them

Researchers from Bangor University, University of Kent, Newcastle University and University of Oxford coded the scripts from the four most recent David Attenborough narrated series. They found the Netflix series Our Planet dedicated 15% of the script to environmental threats and conservation, far exceeding the BBC series Planet Earth II and Dynasties, with only Blue Planet II coming close to this figure.

Early rice farmers unwittingly selected for weedy imposters

Early rice growers unwittingly gave barnyard grass a big hand, helping to give root to a rice imitator that is now considered one of the world's worst agricultural weeds.

Female athletes seek specialty care for concussion later than males

Female athletes seek specialty medical treatment later than male athletes for sports-related concussions (SRC), and this delay may cause them to experience more symptoms and longer recoveries. Researchers from the Sports Medicine Program at Children's Hospital of Philadelphia (CHOP), reported these findings after analyzing electronic health records of sports participants aged 7 to 18.

Synthetic cells capture and reveal hidden messages of the immune system

When immune cells detect harmful pathogens or cancer, they mobilise and coordinate a competent defence response. To do this effectively immune cells must communicate in a way that is tailored to the pathogenic insult. Consequently, the body's response to various health challenges depends on successful coordination among the cells of the immune system.

Defective cilia linked to heart valve birth defects

Bicuspid aortic valve (BAV) is the most common heart valve birth defect and one of the most common birth defects of any type, affecting around 70 million people worldwide. A healthy aortic valve has three leaflets; in BAV disease, two of the leaflets are fused together, impairing the function of the valve. In many individuals with BAV, the valves eventually will have to be replaced or repaired through heart surgery.

Increased risk of prostate cancer in men with BRCA2 gene fault

Men with the BRCA2 gene fault have an increased risk of prostate cancer and could benefit from PSA (prostate specific antigen) testing to help detect the disease earlier, according to researchers funded by Cancer Research UK.
