China could face a catastrophic COVID surge as it lifts restrictions – here’s how it might play out

Given the low level of immunity in China, a major surge would likely see large numbers of hospitalisations and might lead to a dramatic death toll. If we assume, say, 70% of the Chinese population becomes infected over the coming months, then if 0.1% of those infected die (a conservative estimate ), a back-of-the-envelope calculation suggests we’d see around one million deaths.

Strep A: three doctors explain what you need to look out for

Group A streptococcus is a type of bacteria that can live in the back of the throat or on the skin, especially in children. It can spread between people through close contact or coughing and sneezing. In most people, it either causes no illness or only mild throat or skin infections or scarlet fever. Children with scarlet fever have a sandpaper-like rash over their body, often with fever and sore throat and a “strawberry tongue” – where the tongue is red with a white covering.

Pandoravirus: the melting Arctic is releasing ancient germs – how worried should we be?

All the viruses cultured so far are far from viruses that affect mammals, let alone, humans and would be very unlikely to pose a danger to humans. A more relevant area of concern is that as the permafrost thaws it could release the bodies of long-dead people who might have died of an infectious disease and so release that infection back into the world.

Cannabis is no better than a placebo for treating pain – new research

Although cannabis (and cannabis-derived products, such as CBD) may be widely used for reducing pain, how effective it really is in doing this is still unclear. This is what our recent systematic review and meta-analysis sought to uncover. Our study, published in the Journal of the American Medical Association, suggests cannabis is no better at relieving pain than a placebo.

Supreme Court Case Could Curtail Rights of Medicaid Patients

Twenty-two Republican-leaning states have urged the Supreme Court to block beneficiaries of federal safety net programs from suing. If the court agrees participants in many federal entitlement programs could lose the right to go to court when they believe a state, city or county has violated their rights in the administration of those programs.

Endgame: How the Visionary Hospice Movement Became a For-Profit Hustle

It might be counterintuitive to run an enterprise that is wholly dependent on clients who aren’t long for this world, but companies in the hospice business can expect some of the biggest returns for the least amount of effort of any sector in American health care. Medicare pays providers a set rate per patient per day, regardless of how much help they deliver. Since most hospice care takes place at home and nurses aren’t required to visit more than twice a month, it’s not difficult to keep overhead low and to outsource the bulk of the labor to unpaid family members — assuming that willing family members are at hand.

What is ethical animal research? A scientist and veterinarian explain

Federal research agencies follow guiding principles in evaluating the use and care of animals in research.These principles are summarized by the “3 R’s” of animal research: reduction, refinement and replacement. The 3 R’s encourage scientists to develop new techniques that allow them to replace animals with appropriate alternatives.

Weight loss treatments are not a permanent fix – that doesn’t mean they ‘don’t work’

It is often said that 95% of weight-loss measures don’t work. Only, it’s not true. Advances in behavioural treatments (such as cognitive behavioural therapy) for obesity and weight-loss drugs mean there are lots of approaches that help people lose weight. In fact, weight loss is the easy part . The problem is that when you come off a diet or stop taking a weight-loss drug, the weight will invariably creep back up.
