Stomach-protecting medicines can trigger allergies

Stomach-protecting drugs are widely used. Now, using quantitative prescribing data from Austria, a study conducted by MedUni Vienna in collaboration with the Austrian Social Insurance Institutions, has shown that stomach-protecting drugs (especially so-called proton pump inhibitors or PPIs) correlate with subsequent prescriptions for anti-allergy medication. Based on virtually the entire population, this now validates the finding of previous epidemiological and experimental studies that stomach-protecting drugs can intensify or even trigger allergies. The risk of an allergic reaction to allergens that requires anti-allergy treatment is doubled or even tripled. The results were recently published in Nature Communications.

Blood pressure control less likely among those treated in low-income areas

People enrolled in a large clinical hypertension management trial were half as likely to control their blood pressure if they received care at clinics and primary care practices in low-income areas, according to new research in Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.

First pictures of enzyme that drives new class of antibiotics

Understanding how antibiotic scaffolds are constructed in nature can help scientists prospect for new classes of antibiotics through DNA sequencing and genome mining. Researchers have used this knowledge to help solve the X-ray crystal structure of the enzyme that makes obafluorin—a broad spectrum antibiotic agent made by a fluorescent strain of soil bacteria. The new work from Washington University in St. Louis and the University at Buffalo is published July 31 in the journal Nature Communications.

Researchers raise the heat on molten metals to forge future technologies

Solid-state materials are important for developing new technologies, from renewable energy applications to electronics. Manufacturing these advanced materials often requires metal-flux synthesis, a complex process that relies heavily on costly trial-and-error.

Biodiversity highest on Indigenous-managed lands

More than one million plant and animal species worldwide are facing extinction, according to a recent United Nations report. Now, a new UBC-led study suggests that Indigenous-managed lands may play a critical role in helping species survive.

Overturning the truth on conservation tillage

Just as we blend, cut, and fold ingredients together to follow a recipe, farmers use equipment to stir together soil and crop residue (stalks and roots of previous crops) before planting. This mechanical action is called tillage.

Many North American indigenous youth experience symptoms of depression during adolescence

Studies of youth and their experiences with depression have tended not to include Indigenous youth. A new study that analyzed data on the development of depressive symptoms among Indigenous youth in the United States and Canada found that many of the youth had experienced these symptoms during adolescence. The study also identified the risks associated with developing symptoms of depression and how depressive symptoms were associated with alcohol use disorder.

PE fitness tests have little positive impact for students

A new study reveals that school fitness tests have little impact on student attitudes to PE—contrary to polarised views on their merits—and for many students, fitness testing during PE may be wasting valuable class time when used in isolation from the curriculum.

Increased risk of cardiovascular disease for healthy 75-year-olds who stop taking statins

Statins are known to reduce the risk of further problems in patients of any age who have already suffered heart problems or stroke. However, until now it has not been clear how effective their use is in preventing such events occurring in healthy people aged 75 and over, with no previous history of cardiovascular disease.

Early onset of menstruation associated with higher risk of type 2 diabetes

Diabetes is a global health concern expected to affect 693 million people worldwide by 2045. It's been well documented how diet and exercise influence risk of type 2 diabetes; however, a new study suggests that early menarche also is associated with a higher risk, but body mass index (BMI) may mediate this association. Study results are published online today in Menopause, the journal of The North American Menopause Society (NAMS).

Children born to older parents tend to have fewer behavior problems

Since 1995, parents in many Organisation for Economic Cooperation and Development countries and in the United States have been having their first babies at a later age. Amid this trend in delayed childbearing, a new Dutch study considered the behavior problems of children born to older parents. Specifically, researchers looked at externalizing behaviors (e.g., aggression) and internalizing behaviors (e.g., anxiety, depression) of children born to older parents when the youth were 10 to 12 years old. They found that children of older parents tend to have fewer externalizing behavior problems than children of younger parents. The researchers also found that parents' age was unrelated to children's internalizing behaviors.
