A CareCube testing site in Park Slope, Brooklyn, in November 2020. Dave Sanders for The New York Times A Brooklyn-based physicians group is facing a class-action lawsuit accusing it of charging hundreds of dollars for coronavirus tests to New Yorkers who thought they were getting them for free. The lawsuit, filed last week by two Bronx residents, Sabine Schumacher and Linda Cunningham, seeks more than $10 million in damages for the couple and for any New Yorkers who say they were overcharged by the company, CareCube. The complaint claims CareCube illegally charged the couple $450 for two tests taken last June. "It's sad that companies like CareCube are exploiting people during a global pandemic just to make a quick buck, especially in a hard-hit area like New York City," Ms. Cunningham said in a statement. CareCube, which has 20 testing sites citywide, has faced a growing number of reports that it overcharged customers who believed their tests would be free. Last month, L...

Flu Vaccine Effectiveness: Facts, Types, Duration - Verywell Health

Image
The flu vaccine offers protection against four common strains of the flu. The flu vaccine's effectiveness is 40%–60% during years when the most prevalent flu strains match the strains in the vaccine. In reality, flu vaccine effectiveness has ranged from 29%–48% over the five seasons prior to 2020–2021. That means getting the vaccine every year reduces a person's risk of contracting the flu by up to 48% in recent years. The vaccine also reduces the likelihood of severe illness, hospitalization, and death. Because of this, the Centers for Disease Control and Prevention (CDC) recommends that everyone ages 6 months and over get the flu vaccine (with very rare exceptions). There are nine different flu vaccines available for the 2021–2022 flu season. All of them protect against the same four strains of flu. Here's what you should know about flu vaccine effectiveness and types of flu vaccines.  FatCamera / Getty Images Flu Vaccine Ef...

Pimple Secret Popped: How Fat Cells in the Skin Help Fight Acne - UC San Diego Health

Image
Acne is among the most common skin diseases in the United States, according to the American Academy of Dermatology Association, affecting up to 50 million Americans each year. It is also among the least studied.  It's known that hair follicles assist in the development of a pimple, but new research suggests the skin cells outside of these hair follicles play a larger role. The findings published in the February 16, 2022 issue of Science Translational Medicine. Microscopic image of an inflamed pimple with cathelicidin stained red, fat cells stained green and the nuclei of every cell stained blue. Because cathelicidin is produced from fat cells, their staining merges together. "These findings may transform the way we treat acne," said Richard Gallo, MD, PhD, Ima Gigli Distinguished Professor of Dermatology and chair of the Department of Dermatology at UC San Diego School of Medicine.
