Gay dating apps are exposing men to intense pressure to look sexually desirable, fuelling body dissatisfaction and low self-esteem, with some users describing the experience as feeling like they are “selling their body” rather than forming genuine connections. With around 350 million people using dating apps globally, and more than half (51 per cent) of lesbian, gay and bisexual adults reporting they have used one compared to 28 per cent of straight adults, researchers say gay, bisexual and other sexual minority men are among the most active and potentially vulnerable users.

A scientific review published today in the NEJM Evidence journal, coordinated by the D’Or Institute for Research and Education (IDOR), evaluated outcomes of adults with community-acquired pneumonia (CAP) admitted to intensive care units (ICUs) in middle-income countries.

In contrast to high-income countries, where mortality ranges from 16% to 26%, the study found significantly higher rates in the countries analyzed. The work brought together 52 studies and approximately 48,707 patients, revealing an overall mortality rate of 37.1%, which increased to 59.3% among patients requiring respiratory support.

Brief pulses of electrical current can dramatically extend the lives of sea squirts, whose rapid stem cell regeneration and simple immune systems make them a useful analog for understanding aging in humans. The findings point toward new strategies for protecting species from environmental shifts, and mitigating age-related decline.

Regular guava juice consumption may prove a readily accessible and affordable addition to helping lower the risk of anaemia in women in low and middle income countries, suggests a synthesis of the available evidence, published in the open access journal BMJ Nutrition Prevention & Health.
