In March 2020, FDA announced that, due to Coronavirus Disease 2019 (COVID-19), it was postponing almost all inspections of foreign manufacturing establishments. While FDA has indicated it has other tools to ensure the safety of the US drug supply, the lack of foreign inspections removes a critical source of information about the quality of drugs manufactured for the US market.  more »

Can I create my own filter? Some people buy or create masks with a pocket inside to hold a filter, such as a coffee filter. When using other materials to make your own filter, such as unused vacuum cleaner bags, HEPA furnace filters, HVAC anti-allergy filters or other air filters, make sure you sandwich the filter between at least two layers of fabric to cut down on the risk of inhaling potentially harmful fibers from these materials. There are not yet conclusive data on whether or not filters provide added protection, but studies are underway. Please make sure that you can breathe easily when wearing the mask, and do not use a filter if it makes you feel short of breath. more »

There’s no standard federal ratio of staff to residents. A 1987 law requires nursing homes to have a registered nurse on duty eight hours a day, seven days a week; a licensed nurse on duty in the evenings and overnight; and staff “sufficient to meet nursing needs of its residents.” There’s no national data on nursing home staffing during the pandemic, because the federal government has suspended staff reporting requirements to give businesses a break from paperwork. Before the pandemic, the average nursing home could provide 3.9 hours a day of nursing care per patient, according to the most recent federal data. more »

Can we really tell male and female dinosaurs apart? Scientists worldwide have long debated our ability to identify male and female dinosaurs. Researchers analysed skulls from modern-day gharials, an endangered and giant crocodilian species, to see how easy it is to distinguish between males and females using only fossil records. Male gharials are larger in size than females and possess a fleshy growth on the end of their snout, known as a ghara. The research teamstudied 106 gharial specimens in museums across the world. They found that aside from the presence of the narial fossa in males, it was still very hard to tell the sexes apart. more »
