June 5, 2021 marks the 40th anniversary of the first report of AIDS cases and the onset of the American AIDS epidemic. In a new, thought-provoking paper in the New England Journal of Medicine, Columbia professors capture the experiences of the physicians who were central to the AIDS epidemic. In the words of the doctors, they relay what it meant to look back after 40 years and how they "aged together."
Smoking in early puberty in boys may have negative consequences for their future generations of offspring, a study from the University of Bergen (UiB) shows.
Proof of Concept for Real-Time Detection of SARS CoV-2 Infection with an Electronic Nose
A healthy diet around the time of conception through the second trimester may reduce the risk of several common pregnancy complications, suggests a study by researchers at the National Institutes of Health. Expectant women in the study who scored high on any of three measures of healthy eating had lower risks for gestational diabetes, pregnancy-related blood pressure disorders and preterm birth.
Global land-use changes -- including forest fragmentation, agricultural expansion and concentrated livestock production -- are creating "hot spots" favorable for bats that carry coronaviruses and where conditions are ripe for the diseases to jump from bats to humans, finds an analysis published this week by researchers at the University of California, Berkeley, the Politecnico di Milano (Polytechnic University of Milan) and Massey University of New Zealand.
Older adults with cognitive impairment are two to three times more likely to fall compared with those without cognitive impairment.
The malaria parasite Plasmodium vivax may accumulate in the spleen soon after infection to a greater extent than its better-known relative P. falciparum, according to new research published by John Woodford of the University of Queensland, Brisbane, Australia and colleagues in the open access journal PLOS Medicine.
A nationwide study in Sweden estimates the elevated risk of advanced or fatal prostate cancer among relatives of men with the disease, providing new data that could help refine guidelines for the age at which screening should begin. Mahdi Fallah and Elham Kharazmi of the German Cancer Research Center (DKFZ) in Heidelberg, Germany, and colleagues present these new findings in the open-access journal PLOS Medicine.
Observational studies have suggested that increased vitamin D levels may protect against COVID-19. However, these studies were inconclusive and possibly subject to confounding. A study published in PLOS Medicine by Guillaume Butler-Laporte and Tomoko Nakanishi at McGill University in Quebec, Canada, and colleagues suggests that genetic evidence does not support vitamin D as a protective measure against COVID-19.
Plasmodium vivax malaria is a mosquito-borne illness that causes significant morbidity. However, the household and healthcare provider costs of the disease are unknown. A new study published in the open-access journal PLOS Medicine by Dr Angela Devine at Menzies School of Health Research in Australia, and colleagues estimate the global economic burden of P. vivax for the first time using country-level data.
