There is a problem with the recently approved Alzheimer’s drug, Aduhelm. It can remove some of the amyloid that forms brain plaques that are hallmarks of the disease. But most of the drug is wasted because it hits an obstacle, the blood-brain barrier, that protects the brain from toxins and infections but also prevents many drugs from entering.Researchers wondered if they could improve that grim result by trying something different: they would open the blood-brain barrier for a short time while they delivered the drug. Their experimental method was to use highly focused pulses of ultrasound along with tiny gas…

Marijuana is neither as risky nor as prone to abuse as other tightly controlled substances and has potential medical benefits, and therefore should be removed from the nation’s most restrictive category of drugs, federal scientists have concluded.The recommendations are contained in a 250-page scientific review provided to Matthew Zorn, a Texas lawyer who sued Health and Human Services officials for its release and published it online on Friday night. An H.H.S. official confirmed the authenticity of the document.The records shed light for the first time on the thinking of federal health officials who are pondering a momentous change. The agencies…

A panel of experts affiliated with the United Nations has warned that the population of the Gaza Strip is at imminent risk of famine, with more than 90 percent of its 2.2 million people facing “acute food insecurity” and a quarter of the population experiencing “catastrophic levels of hunger.”Even before the war between Israel and Hamas, nearly 70 percent of Gazans were dependent on humanitarian assistance for food because the territory has been under Israeli and Egyptian blockade since 2007. Now, only 20 to 30 percent of what people there need is being permitted over the border into Gaza, according…

In early 2020, the Food and Drug Administration responded to decades of escalating concerns about a commonly prescribed drug for asthma and allergies by deploying one of its most potent tools: a stark warning on the drug’s label that it could cause aggression, agitation and even suicidal thoughts.The agency’s label, which was primarily aimed at doctors, was supposed to sound an alert about the 25-year-old medication, Singulair, also known by its generic name, montelukast. But it barely dented use: The drug was still prescribed to 12 million people in the United States in 2022.Children face the greatest risks of the…

The Food and Drug Administration has allowed Florida to import millions of dollars worth of medications from Canada at far lower prices than in the United States, overriding fierce decades-long objections from the pharmaceutical industry.The approval, issued in a letter to Florida Friday, is a major policy shift for the United States, and supporters hope it will be a significant step forward in the long and largely unsuccessful effort to rein in drug prices. Individuals in the United States are allowed to buy directly from Canadian pharmacies, but states have long wanted to be able to purchase medicines in bulk…

Monique Louvigny, an event coordinator in the San Francisco Bay Area, economizes where she can. She drives a 10-year-old Prius, brings a thermos of coffee to work instead of patronizing a place with baristas, and takes advantage of a drive-through food pantry once a month.Laid off at 57, “I kind of reinvented myself,” she said. She rebuilt her career as a freelancer, overseeing receptions and conventions for many companies and institutions, including the local de Young and Legion of Honor art museums.But her income fell to less than $30,000 last year. “It’s erratic,” she said. “In January, I have 12…
