University students in France who experienced quarantine during COVID-19 were surveyed to assess how common were mental health issues and to identify factors associated with these disorders.
NRL researchers evaluated commercial ultraviolet (UV) sources for viral disinfection to combat COVID-19 on land and at sea, and established a dedicated UV characterization lab in five days.
Giving preventive drugs to school-age children in Africa substantially reduces malaria infections and cases of anaemia, according to a new study in The Lancet Global Health.
A recent paper published in the journal PLOS ONE, outlines how researchers with the University of Tennessee College of Veterinary Medicine and Department of Forestry, Wildlife and Fisheries, measured the attitudes, practices and zoonoses awareness among community members associated with the bushmeat trade in northern Uganda.
Virologists at Institut national de la recherche scientifique (INRS) have identified a critical role played by a cellular protein in the progression of Hepatitis C virus infection, paving the way for more effective treatment. No vaccine currently exists for Hepatitis C virus infection, which affects more than 130 million people worldwide and nearly 250,000 Canadians. Antivirals exist but are expensive and not readily available in developing countries, where the disease is most prevalent.
Analysis suggests that individual measures (including school closure, workplace closure, public events ban, ban on gatherings of more than ten people, requirements to stay at home, and internal movement limits) are associated with a reduction in transmission of SARS-CoV-2 but combined measures are more effective at reducing transmission, according to a modelling study published in The Lancet Infectious Diseases journal.
The study published in the journal Immunity reveals that tetracyclines (broad spectre antibiotics), by partially inhibiting cell mitochondria activity, induce a compensatory response on the organism that decreases tissue damage caused during infection. This finding opens new doors in the field of disease tolerance and positions this group of antibiotics as potential adjuvant treatment for sepsis, due to their effects that go beyond the control of bacterial burden.
The "mismatch hypothesis" argues that our bodies evolved to digest the foods that our ancestors ate, and that human bodies will struggle and largely fail to metabolize a radically new set of foods. This intuitive idea is hard to test directly, but the Turkana, a pastoralist population in remote Kenya, present a natural experiment: genetically homogenous populations whose diets stretch across a lifestyle gradient from relatively "matched" to extremely "mismatched" with their recent evolutionary history.
A microRNA that can be found in a blood sample may make it easier to detect gastric cancer and could lead to improved treatment for the disease and others like it that are resistant to common immunotherapies.
As countries struggle to contain the COVID-19 pandemic, vaccination uptake is a public health priority now more than ever. Efforts to increase vaccinations vary greatly around the globe. A new McGill-led study comparing policies around the world finds broad implementation of mandatory vaccination mandates. However, the penalties for failing to vaccinate differ significantly by country, ranging from fines to jail time.
