As cannabis use among youth rises in Canada — and THC potency reaches record highs — emergency departments are seeing a surge in cases of a once-rare condition: cannabis hyperemesis syndrome (CHS).

I was glad to hear from BBC crowd science (the linked show) that I’m not alone in hearing a hum. People around the world hear a low frequency (50 Hz) hum.

Tracking measles through wastewater is giving health officials a new window into where the virus is spreading.

The United States has, for 70 years, been fighting a continuous aerial war against the New World screwworm, a parasite that eats animals alive: cow, pig, deer, dog, even human. (Its scientific name, C. hominivorax, translates to “man-eater.”) Larvae of the parasitic fly chew through flesh, transforming small nicks into big, gruesome wounds. But in the 1950s, the U.S. Department of Agriculture laid the groundwork for a continent-wide assault. Workers raised screwworms in factories, blasted them with radiation until they were sterile, and dropped the sterile adult screwworms by the millions—even hundreds of millions—weekly over the U.S., then farther south in Mexico, and eventually in the rest of North America.

Health nonprofits and medical interpreters warn that federal cuts have eliminated dozens of positions in California for community workers who help non-English speakers sign up for insurance coverage and navigate the health care system.

Social media posts from residents of Bosnia and Herzegovina's capital have shown an abundance of rodents swimming in the Miljacka river which flows through the centre of the city.

Colton George felt sick. The 9-year-old Indiana boy told his parents his stomach hurt. He kept running to the bathroom and felt too ill to finish a basketball game.

Moving forward, the FDA will adopt the following Covid-19 vaccination regulatory framework: On the basis of immunogenicity — proof that a vaccine can generate antibody titers in people — the FDA anticipates that it will be able to make favorable benefit–risk findings for adults over the age of 65 years and for all persons above the age of 6 months with one or more risk factors that put them at high risk for severe Covid-19 outcomes, as described by the CDC (Figure 2). For all healthy persons — those with no risk factors for severe Covid-19 — between the ages of 6 months and 64 years, the FDA anticipates the need for randomized, controlled trial data evaluating clinical outcomes before Biologics License Applications can be granted. Insofar as possible, when approving a Covid-19 vaccine for high-risk groups, the FDA will encourage manufacturers to conduct randomized, controlled trials in the population of healthy adults as part of their postmarketing commitment.

The presence of antibiotics in surface waters poses risks to aquatic ecosystems and human health due to their toxicity and influence on antimicrobial resistance. After human consumption and partial metabolism, antibiotic residues are excreted and undergo complex accumulation and decay processes along their pathway from wastewater to natural river systems. Here, we use a global contaminant fate model to estimate that of the annual human consumption of the 40 most used antibiotics (29,200 tonnes), 8,500 tonnes (29%) are released into the river system and 3,300 tonnes (11%) reach the world's oceans or inland sinks. Even when only domestic sources are considered (i.e. not including veterinary or industrial sources), we estimate that 6 million km of rivers worldwide are subject to total antibiotic concentrations in excess of thresholds that are protective of ecosystems and resistance promotion during low streamflow conditions, with the dominant contributors being amoxicillin, ceftriaxone, and cefixime. Therefore, it is of concern that human consumption alone represents a significant risk for rivers across all continents, with the largest extents found in Southeast Asia. Global antibiotic consumption has grown rapidly over the last 15 years and continues to increase, particularly in low- and middle-income countries, requiring new strategies to safeguard water quality and protect human and ecosystem health.

Question Is a multicomponent vaccine against seasonal influenza and SARS-CoV-2 (mRNA-1083) immunogenic and well-tolerated in adults 50 years and older?

It's hard to believe opioid deaths are dropping when you're walking on Vancouver's Downtown Eastside, where B.C.'s drug crisis is most visible.

Downward trend in deaths appears stalled due to lack of urgency among doctors, patients, along with healthcare barriers

Titanium dioxide is the most widely used whitening pigment in the world and has been linked to adverse health effects, particularly genotoxicity and intestinal inflammation. It is applied as food coloring and a whitening agent to a wide variety of foods, including chewing gum, cakes, candies, breads and ice cream.

At least 156 million Americans, about 46 percent of the population, live with unsafe levels of ozone, particulate pollution or both, according to the American Lung Association’s annual State of the Air report.

In the summer of 1982, seven heroin users were admitted to a California hospital paralyzed and mute. They were in their 20s, otherwise healthy — until a synthetic drug they had manufactured in makeshift labs left them frozen inside their own bodies. Doctors quickly discovered the cause: MPTP, a neurotoxic contaminant that had destroyed a small but critical part of the brain, the substantia nigra, which controls movement.
