New wearable device may help treat common sleep problem: ‘Gold standard'
People suffering from sleep issues may soon be able to rest easier, thanks to a new wearable device that could revolutionize the way we get our shut-eye.
Unveiled at the American Thoracic Society's 2025 International Conference, the device is a ring-shaped pulse oximeter that appears to be effective at monitoring obstructive sleep apnea (OSA) and other common sleep-related breathing problems.

Unlike traditional polysomnography (PSG) tests, which require overnight stays in sleep labs with numerous wires and sensors, this wearable allows for easy at-home use over extended periods.
It connects to a smartphone app, providing both patients and healthcare providers with access to sleep data.
'This offers the opportunity for shared decision making between patient and provider using digital medicine,' Ketan Mehta, head of product and engineering for Connected Wearables at Apnimed, said in a press release.

In a clinical trial, patients were meant to wear the device for 9 nights over a 47-day period.
However, 85% of participants used it beyond the recommended length of time, with one patient wearing it for 44 nights.
'One sleep specialist even reported that it may be better to collect one or two channels of data over 25 nights than 25 channels over one night, which is considered the gold standard with in-lab polysomnography,' Mehta said.

While popular devices like the Apple Watch and Oura ring have introduced sleep apnea detection features, they are not yet cleared for medical use.

This new ring-shaped device, however, is FDA-approved — bridging the gap between cumbersome clinical equipment and less reliable consumer wearables.
The introduction of this device aligns with a broader trend of developing comfortable, at-home sleep monitoring solutions.

Earlier this year, researchers at the University of Cambridge introduced 'smart pajamas' capable of detecting sleep disorders — including apnea — with 98.6% accuracy.

'Poor sleep has huge effects on our physical and mental health, which is why proper sleep monitoring is vital,' said Luigi Occhipinti, a professor at the University of Cambridge who led the research.
'However, the current gold standard for sleep monitoring, polysomnography or PSG, is expensive, complicated and isn't suitable for long-term use at home.'
Sleep apnea is a common sleep disorder where breathing repeatedly stops and starts during sleep, often due to a blocked airway or poor brain signaling.
If left untreated, it can lead to serious health risks including high blood pressure, heart disease, stroke, diabetes and daytime fatigue that increases the likelihood of accidents.

Blue states call on FDA to expand abortion pill access
Attorneys general of New York, California, New Jersey and Massachusetts are asking the Food and Drug Administration (FDA) to expand access to the abortion pill and remove some 'unnecessary' drug restrictions that have been in place for more than two decades. The joint petition, filed Thursday, comes days after FDA Commissioner Marty Makary committed to reviewing the abortion drug amid pressure from Department of Health and Human Services Secretary Robert F. Kennedy Jr. and some Republican lawmakers. The FDA first approved of the use of mifepristone and misoprostol for an abortion in 2000. Unlike surgical abortions, medication abortions do not need to take place in a clinical setting, and patients are able to take the pills at home. Most abortions in the U.S. are now medication abortions, according to data from the reproductive health and rights group Guttmacher Institute. In 2023, 63 percent of all abortions in the U.S. were medication abortions. The safety of mifepristone has come under increased scrutiny by some Republican lawmakers, citing a flawed study claiming the rate of adverse health events that occur among patients is far higher than previously reported. More than 100 scientific studies have been conducted looking at the safety and efficacy of mifepristone and misoprostol; all of them have found that the drugs are a safe way to terminate a pregnancy. 'Given Mifepristone's 25-year safety record, there is simply no scientific or medical reason to subject it to such extraordinary restrictions,' New York Attorney General Letitia James said. 'The FDA must follow the science and lift these unnecessary barriers that put patients at risk and push providers out of care.' Mifepristone's use is subject to a Risk Evaluation and Mitigation Strategy (REMS) program under the FDA. The attorneys general argue three requirements under the REMS program for the drug should be removed since they pose a burden to patients and health care systems. The first is related to prescriber certification. As part of the REMS program, health care providers who prescribe mifepristone are required to add their names to national and abortion provider lists, which the attorneys general say raise 'serious safety and legal concerns.' The second has to do with patient agreement forms. All patients who want mifepristone — even those using the drug to treat a miscarriage — are required to sign a document stating they are using the drug to end a pregnancy. The third requirement mentioned in the petition is connected to pharmacy certification. As part of mifepristone's REMS program, pharmacies that carry the drug are subject to tracking, shipping and reporting requirements, which the attorneys general argue may 'dissuade' some from carrying the drug. The FDA has yet to reply to a request for comment from The Hill about the petition.

Albertsons Food Recalled in 12 States as FDA Issues Most Severe Risk Level
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. Albertsons Companies has issued a voluntary recall of multiple store-prepared Greek salad products sold across 12 states and Washington, D.C. The U.S. Food and Drug Administration (FDA) has classified the alert as a Class I recall—its highest and most urgent warning level. The salads were made using cucumbers linked to a multistate salmonella outbreak traced back to Bedner Growers Company. Newsweek has contacted Albertsons, via email, and Bedner Growers Company, via online contact form, for comment. Why It Matters A Class I recall is reserved for products that pose a serious health risk with a "reasonable probability" of causing illness or even death if consumed. The recalled Greek salads were sold under several store brands in high-traffic northeastern grocery chains. The FDA warning elevates the urgency for consumers who may still have the product in their refrigerators, particularly those with compromised immune systems, children, and elderly individuals more vulnerable to foodborne illnesses. What to Know Recalled Products: AMCE Greek Salad AUTHENTIC FS Sold refrigerated in clear plastic containers by the pound UPC: 293070 ##### READY MEALS Greek Salad SS Sold refrigerated in clear plastic containers by the pound UPC: 292483 ##### Star Market Greek Salad FS Sold refrigerated in clear plastic containers by the pound UPC: 292329 ##### Reason for Recall: All three products contain cucumbers from Bedner Growers Company, which were previously recalled due to contamination with salmonella, a bacteria known to cause serious gastrointestinal illness. The outbreak has been under ongoing investigation by public health authorities. Where the Recall Applies: The salads were sold at stores in the following states: Connecticut Delaware Maine Massachusetts Maryland New Hampshire New Jersey New York Rhode Island Pennsylvania Vermont Virginia Washington, D.C. The affected salads were primarily sold in ACME, Star Market, and Ready Meals outlets. What People Are Saying Albertsons Companies stated in its press release that it is "committed to the highest standards of food safety" and that the recall was initiated "out of an abundance of caution." No illnesses have been officially linked to the salads yet, but the company has urged customers who purchased any of the listed products to discard them immediately or return them to the store for a full refund. The FDA emphasized the seriousness of the recall, pointing to the ongoing multistate salmonella outbreak and reiterating its warning that contaminated food—even if it looks or smells normal—can be dangerous. What's Next The full scope of the salmonella outbreak connected to the contaminated cucumbers is being investigated. Consumers are advised to check their refrigerators for any of the recalled Greek salad items and follow safety instructions. Albertsons said affected stores are posting notices and removing products from shelves. Additional recalls may be issued if more prepared foods containing the same contaminated cucumbers are identified.

Wedgewood Pharmacy Adds GS-441524 to Its FIP Treatment Portfolio
SWEDESBORO, N.J., June 05, 2025--(BUSINESS WIRE)--Wedgewood Pharmacy today announced the availability of a GS-441524 formula, a compounded oral antiviral formulation now part of its feline infectious peritonitis (FIP) treatment capabilities. With this addition, veterinarians can now prescribe both GS-441524 and Molnupiravir for their patients, two of the most requested compounded antivirals for FIP, through a single trusted source backed by pharmacist support and FDA-registered ingredient sourcing. GS-441524 can be compounded as a 50mg/ml flavored oral oil suspension in multiple sizes, to improve compliance and ease of administration. The addition complements Wedgewood's Molnupiravir formulations, giving veterinarians access to two antivirals with distinct mechanisms of action. "FIP is one of the toughest diagnoses we face, not just clinically, but emotionally too," said Dr. Rae Hutchins, Chief Veterinary Officer at Wedgewood. "For a long time, vets had to deal with inconsistent access and quality when it came to GS-441524. Now, by offering both GS-441524 and Molnupiravir from one trusted, pharmacist-supported source, we're making it easier for veterinarians to focus on what matters most, giving their patients the best possible chance." "Having access to both GS-441524 and Molnupiravir compounded formulations through Wedgewood not only widens access to affordable FIP treatment across the US, but it also gives veterinarians the ability to easily choose and adapt treatment to best suit the needs of their patients and clients," said Nicole Jacque, co-founder of FIP Global Cats. "Having pharmacists who understand the urgency and complexity of these cases partnering with veterinarians is key to ensuring the best treatment outcomes for cats with FIP." Until recently, many veterinarians relied on fragmented or unregulated sources for GS-441524, making it difficult to ensure consistency and continuity of care. The introduction of this option through Wedgewood reflects a direct response to those challenges, providing prescribers with a trusted, quality-assured formulation from a pharmacy they can count on. The launch of GS-441524 builds on Wedgewood's long-standing role in supporting veterinarians with customized treatment solutions for complex cases. As part of its commitment to responsible compounding, the pharmacy emphasizes that its GS-441524 formulation is not approved by the FDA, has not been studied in clinical trials, and Wedgewood makes no claims of efficacy or safety. Independent third-party studies related to GS-441524 are available for veterinary reference through Wedgewood's FIP Resource Center.
