  • More than 2 million people got infected by human immunodeficiency virus (HIV) in 2015, being sexual transmission the main channel of infection. Researchers from the Infections of the Respiratory Tract and in Immunocompromised Patients group of the Bellvitge Biomedical Research Institute (IDIBELL), led by Dr. Daniel Podzamczer, have evaluated the speed at which a new antiretroviral drug, Dolutegravir, is able to reduce the viral load in semen, an area of the body considered to be a reservoir of the virus and where access for drugs is more difficult. The results, published in Journal of Infectious Diseases, show the potential of these new treatments to reduce the chances of sexual transmission of the virus.

  • Pembrolizumab (trade name: Keytruda) was initially introduced for the treatment of melanoma. Since July 2016, the monoclonal antibody has also been available for the treatment of locally advanced or metastatic non-small cell lung cancer (NSCLC) in adults whose tumours express the T-cell receptor ligand PD-L1 and who have received a prior chemotherapy regimen. The German Institute for Quality and Efficiency in Health Care (IQWiG) examined in a dossier assessment whether the drug offers an added benefit over the appropriate comparator therapy also for these patients.

    Upsalite® inhibits bacteria without penicillin

    In a study published in ACS Omega, researchers at Uppsala University have shown that the mesoporous magnesium carbonate Upsalite® exerts strong bacteriostatic effect on Staphylococcus epidermidis, associated with acne and hospital acquired infections.

  • Scientists from the National Institutes of Health have identified an antibody from an HIV-infected person that potently neutralized 98 percent of HIV isolates tested, including 16 of 20 strains resistant to other antibodies of the same class. The remarkable breadth and potency of this antibody, named N6, make it an attractive candidate for further development to potentially treat or prevent HIV infection, say the researchers.

  • An experimental kidney cancer drug outperformed the standard first-line therapy for patients with metastatic disease who are considered at risk for poorer than average outcomes, according to results of a randomized phase II clinical trial by researchers at Dana-Farber Cancer Institute.

  • Most antibiotics in use today are based on natural molecules produced by bacteria--and given the rise of antibiotic resistance, there's an urgent need to find more of them. Yet coaxing bacteria to produce new antibiotics is a tricky proposition. Most bacteria won't grow in the lab. And even when they do, most of the genes that cause them to churn out molecules with antibiotic properties never get switched on.

  • By removing the protein galectin-3 (Gal3), a team of investigators led by University of California School of Medicine researchers were able to reverse diabetic insulin resistance and glucose intolerance in mouse models of obesity and diabetes.

  • B12 deficiency during pregnancy may predispose children to metabolic problems such as type-2 diabetes, according to research presented today at the Society for Endocrinology's annual Conference in Brighton. These findings could lead to a review of current vitamin B12 requirements for pregnant women, whether through an improved diet or supplements.
