Staying at elementary school for longer associated with higher student attainment

A new study has discovered that U.S. students achieve better results in reading and mathematics tests when they stay in elementary school for grades six (age 11–12) and seven (age 12–13), rather than transfer to middle school. In contrast, students in grade eight (age 13–14) achieve better results in middle school than high school.

Tumor resistance is promoted by anti-cancer protein

Lack of oxygen, or hypoxia, is a biological stressor that occurs under various conditions such as wound healing and stroke. To rescue the tissue, the body has innate mechanisms that "kick in" to make the cells of the hypoxic tissue more resistant and assist in tissue repair. One such mechanism is the expression of a protein called Hypoxia Induction Factor (HIF), which controls several processes such as glucose uptake, growth of blood vessels and cell proliferation. Despite its beneficial role in some diseases, HIF has also been found to be an important contributor towards cancer progression.

Medications underused in treating opioid addiction, expert says

Child's gluten intake during infancy linked to increased risk of developing type 1 diabetes

New research presented at the Annual Meeting of the European Association for the Study of Diabetes (EASD) in Barcelona, Spain (16-20 September) shows that a child's intake of gluten at age 18 months is associated with a 46% increased risk of developing type 1 diabetes for each extra 10g of gluten consumed. There was no association found between the mother's intake of gluten during pregnancy and type 1 diabetes in her child, conclude the authors who include Dr. Nicolai Lund-Blix, Oslo University Hospital, and the Norwegian Institute of Public Health, Oslo, Norway.

Researchers identify new target regulating mitochondria during stress

Like an emergency response team that is called into action to save lives, stress response proteins in the heart are activated during a heart attack to help prevent cell death. As part of this process, Lewis Katz School of Medicine at Temple University researchers show for the first time that one of these specialized emergency responder proteins, known as MCUB, temporarily decreases harmful levels of calcium transport into mitochondria, the energy-generating batteries of cells.

Protective effect of breastfeeding on childhood obesity risk linked to leptin gene modification

Breastfed children have a lower risk of obesity, which may be linked to reduced expression of the hormone, leptin; according to research presented today at the 58th Annual European Society for Paediatric Endocrinology Meeting. The study reported that genetic modifications known to suppress leptin levels were more common in breastfed babies than formula-fed, and that these differences may play a role in the development of obesity. Understanding the link between genetic modification of leptin and obesity risk could advance strategies to prevent and treat childhood obesity and, its complications, in the future; as prevention is better than cure.

Patients with high blood sugar variability much more likely to die than those with stable visit-to-visit readings

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 patients with the highest variability in their blood sugar control are more than twice as likely to die as those with the most stable blood sugar measurements. The study is by Professor Ewan Pearson, University of Dundee, UK and Dr. Sheyu Li, West China Hospital, Sichuan University, Chengdu, China, and University of Dundee, UK, and colleagues.

Underweight babies more likely to develop type 2 diabetes more than a year earlier

Previous research has shown that people born weighing 2.7 kg (6 lbs) or less face an increased risk of developing type 2 diabetes (T2D) as adults. New research being presented at this year's European Association for the Study of Diabetes (EASD) Annual Meeting in Barcelona, Spain (16-20 September) is the first study to show that babies born underweight are more likely to develop type 2 diabetes at a younger age (by more than one year) and have less severe obesity at the time of diabetes diagnosis with higher concentrations of HDL cholesterol (known as good cholesterol).

Poor diabetes control costs the NHS in England 3 billion a year in potentially avoidable hospital treatment

Poor diabetes control was responsible for £3 billion in potentially avoidable hospital treatment in England in the operational year 2017-2018, according to new research comparing the costs of hospital care for 58 million people with and without diabetes.
