The use of GLP-1 analog diabetes drugs-such as semaglutide, sold under the trade name Ozempic-is not linked to an increased risk of suicide, according to two studies published in JAMA Internal Medicine. The first, led by a U.S. team, analyzes data from more than 3,300 people who have participated in clinical trials. The second analyzes data from 124,517 users of these drugs in Sweden and Denmark, and compares them with an even larger group of people who used another type of diabetes medication.
A paper published today in the journal Science explores the potential of glucagon-like peptide-1 (GLP-1)-based drugs such as semaglutide to treat diseases beyond diabetes and obesity. For example, recent studies suggest that they could improve conditions ranging from depression to neurological disorders to cardiovascular and kidney disease.
The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has recommended granting marketing authorisation in the European Union for Eurneffy (epinephrine), the first nasally administered medicine for the emergency treatment of allergic reactions. Anaphylaxis is the most severe form of allergic reaction that can occur within minutes of exposure to an allergen and can be life-threatening. Until now, treatment with epinephrine (also known as adrenaline) to reduce the anaphylactic reaction is done by intramuscular injection.
The Spanish Agency of Medicines and Health Products (AEMPS) has announced that the anti-obesity drug Wegovy (semaglutide) will be available, with a doctor’s prescription, starting from May. It is the same active ingredient as Ozempic, but for patients without diabetes.
A multidisciplinary study involving several Spanish research groups has preclinically tested a new type of immunotherapy for multiple myeloma. Instead of modifying T cells to attack the tumour directly, as CAR-T cells do, they have managed to make them secrete bispecific antibodies, which bind to the tumour on one side and to other T cells on the other, attracting them to the tumour. According to the authors, this cell therapy was more effective than traditional CAR-Ts and could generate less resistance. The results are published in the journal Science Translational Medicine.
Two teams of researchers have separately described a population of memory lymphocytes that may be responsible for the persistence of allergies over time. The work has analysed responses to allergens such as those present in peanuts, dust and birch. According to the authors, whose research is published in Science Translational Medicine, these cells could serve as a target for the treatment of various types of allergies.
The Royal Swedish Academy of Sciences has awarded the 2023 Nobel Prize in Physics to Pierre Agostini, Ferenc Krausz and Anne L'Huillier for developing "experimental methods generating attosecond light pulses". These advances made it possible to observe the motion of particles in atoms on the shortest time scale captured by humans. An attosecond is a unit of time equivalent to one trillionth of a second, roughly the time it takes light to travel the diameter of an atom.
Glyphosate is one of the most widely used herbicides in the world. New work published in Science reveals that it significantly impairs the ability of bumblebees to maintain the temperature of their hive, a hitherto unsuspected effect that may lead to the decline of this already endangered species, which is essential for pollination.
