The pepperoni pizza hypothesis

Researchers at Northwestern University believe spicy food, including pepperoni pizza, can worsen pelvic pain and urinary frequency in women with interstitial cystitis. A new treatment approach using anesthetic patches or suppositories may provide relief.

Learning how not to be afraid

Mice conditioned for safety display reduced anxiety in stressful situations, comparable to antidepressant medications. The study reveals learned safety influences brain development, including increased expression of brain-derived neurotrophic factor and dopamine neurotransmitters.

Waterborne disease risk upped in Great Lakes

A new study suggests that increased climate-related extreme rainfall events in the Great Lakes region will aggravate the risk for outbreaks of waterborne disease. The researchers found a potential 10 to 40% increase in extremely heavy precipitation events, leading to greater potential for flooding and sewage overflow into Lake Michigan.

Genome of a monkey-human malaria parasite

The genome of Plasmodium knowlesi, a mosquito-human malaria parasite, has been decoded, revealing unique genetic features that enable it to evade host immune systems. The study found that the parasite's genes are scattered throughout its genome, unlike other malaria parasites, and that it uses molecular mimicry to survive and propagate.

Guidelines urge physical activity during pregnancy

The new guidelines recommend at least 150 minutes of moderate-intensity aerobic activity per week during pregnancy, with benefits including reduced risk of complications and improved long-term child health. Regular postpartum physical activity also supports a woman's overall health and weight management.

Pollution from livestock farming affects infant health

A new study in the American Journal of Agricultural Economics explores the effects of livestock facility pollution on infant health. The research found a strong positive relationship between livestock production and infant mortality, with an estimated 7.4% increase in infant deaths for every 100% increase in livestock production.

U of T creates fake proof personality test

Psychologists at U of T create a bias-resistant personality inventory that predicts real-world performance even when respondents are trying to fake their answers. The study shows that traditional personality questionnaires fail to predict outcomes when respondents have strong incentive to distort the results.

What is the influence of tumor removal on the serum level of carbohydrate's antibody?

Research found that surgical tumor removal significantly elevated serum levels of TF and Tn antibodies in gastrointestinal cancer patients, particularly those with G3 tumors. The postoperative follow-up showed a correlation between the level of anti-TF IgG and lymphocyte count, as well as between anti-Tn IgG and serum CA 19-9 levels.

Climate change will affect public health -- a call to action

A special issue of the American Journal of Preventive Medicine examines the intersection of climate change and health, highlighting various impacts including heat-related illnesses, vectorborne diseases, and air quality issues. The issue emphasizes the need for a systems approach to address climate change and its effects on public health.
