Thousands of nurses at several major New York City hospitals have gone on strike. The strike began Monday morning after negotiations through the weekend failed to yield a breakthrough. The affected hospitals include NewYork-Presbyterian, Montefiore and Mount Sinai. The union says about 15,000 nurses are participating in the strike. Among the nurses' demands are manageable workloads and more workplace security. Hospitals say the union's demands are too costly.

IV therapy clinics are springing up around the country, touting quick ways to recover from a hangover or a hard workout. But doctors and regulators preach caution before plunging into a visit. The service has been on a growth spurt since the COVID-19 pandemic, offering drips that also aim to boost energy levels or immune systems or deal with things like joint pain. Regulators worry about who delivers the treatments, the source of any pharmaceuticals used and how the services are provided. Customers should come prepared to ask questions before they get connected.
