In over a decade, for the first time, obesity rates in the United States is declining. As per a recent study published last Friday in the journal JAMA Health Forum, it was found that the obesity numbers in the United States have gone down slightly from 46% in 2022 to 45.6% in 2023. While it is only a slight decline, it is also important to note that it is the first drop recorded in almost a decade.

"What we're seeing for the first time is that curve is bending and shows a sign of hope for something that was really a threat to American public health for so many years," said John Brownstein, co-author of the study, who is also the chief innovation officer at Boston Children's Hospital and a professor at Harvard Medical School.

How was the study conducted?

The study reviewed the body mass index (BMIs), a measure of obesity of 16.7 million US adults over a 10-year period. The average BMI rose annually to 30.25, which is considered obese, however, after 2022, a different trend was noticed. It plateaued in 2022, and then dropped to 30.21 in 2023.

Weight Loss Drugs

Brownstein and his team also noted that women and adults aged 66 to 75 saw the greatest drop in obesity rates. Whereas people who live in the South, where there was the highest dispensing rate of weight loss drugs, also known as the GLP-1 receptor agonist, also so a sharp decline in obesity.

Semaglutide is also one of the drugs in the class of the GLP-1 agonists, and also an active agent found in the popular drug like Ozempic and Wegovy. The United States also saw a 700% increase in the use of weight loss drugs, and not as a side-product for diabetes, but specifically for weight loss from 2019 to 2023, mentions a 2024 study titled Shifting Trends in the Indication of Glucagon-like Peptide-1 Receptor Agonist Prescriptions: A Nationwide Analysis, published in the Annals of Internal Medicine. However, these medicines are also used to mainly treat type 2 diabetes or combination of diabetes and obesity.

This is, what Brownstein thinks, has helped a slight decline in the obesity rates in the United States.

What are the other reasons?

Brownstein mentions that there are other reasons too for this slight decline. For instance, looking at the pharmacy prescription, it was seen that while South had the highest dispensing rate of weight loss medication, this area also saw a disproportionately high number of COVID-19 deaths, especially among its obese population.

Another reason, mentions Benjamin Reader, paper's co-author and an assistant professor at Harvard Medical School, is the change in lifestyle. "You have this emergence from COVID, of which people are potentially starting to be more active again, stopping the sedentary habits that they picked up during COVID," said Reader. "All of these forces are at play, and I don't think we can disentangle them from this data."

However, obesity still remains a critical public health issue. Other experts have pointed out that there is a need to look at this positive indicator in a specific database. While this could mean that people are doing better, however, it is also important to see if these factors last long and how the rats play out over time. As of now, as per the Centers for Disease Control and Prevention, nearly 60% of the adults in the United States are obese, and have high blood pressure, while 23% have diabetes.

Covid could have accelerated arterial ageing by up to five years, with women experiencing the greatest impact, according to groundbreaking research. The study revealed that even mild Covid infections can stiffen blood vessels, a change normally linked to aging, which increases the risk of heart attacks, strokes, and other cardiovascular issues.

Encouragingly, vaccinated individuals generally showed less arterial stiffness compared to those who were unvaccinated. Study leader Professor Rosa Maria Bruno explained that many people affected by Covid continue to experience symptoms months or even years later, and researchers are “still uncovering how the virus triggers these lingering effects.”

The findings follow advice from an emergency doctor who recently highlighted a simple five-second test that could indicate heart problems.

Early Vascular Ageing Explained

Professor Bruno said: “We know Covid can directly impact blood vessels. This can lead to what we term early vascular aging, meaning your arteries are older than your actual age, increasing susceptibility to heart disease. Identifying at-risk individuals early is crucial to preventing heart attacks and strokes.”

How the Study Was Conducted

The research included 2,390 participants from 16 countries, including the UK and the US. Conducted from September 2020 to February 2022, participants were divided into four groups: those who never contracted Covid, those with recent mild infections who were not hospitalised, patients admitted to general wards, and the most severe cases treated in intensive care.

Stiffer Arteries Found Across All Covid Groups

The results were striking as all Covid-infected groups, including those with mild infections, showed stiffer arteries than people who had never been infected. Women were more affected than men, and individuals with long Covid symptoms like fatigue and shortness of breath showed the strongest vascular changes.

Reassuringly, vaccinated participants had less stiff arteries than unvaccinated ones, and over time, the Covid-related vascular ageing tended to stabilise or slightly improve.

How Arterial Stiffness Was Measured

Researchers determined vascular age by measuring how fast a blood pulse travels from the carotid artery in the neck to the femoral arteries in the legs, using a device to calculate carotid-femoral pulse wave velocity (PWV). A higher PWV indicates stiffer blood vessels and a higher vascular age. Measurements were taken six months after infection and repeated at 12 months. The analysis accounted for participants’ sex, age, and other cardiovascular risk factors.

The study found that PWV increased in women by 0.55 metres per second for mild Covid cases, 0.60 for hospitalised women, and 1.09 for those in intensive care. Researchers note that an increase of 0.5 metres per second is “clinically significant,” roughly equivalent to five years of vascular ageing, and raises the cardiovascular risk by 3 percent in a 60-year-old woman.

How Covid Affects Blood Vessels

Professor Bruno from Université Paris-Cité explained: “Covid-19 targets angiotensin-converting enzyme 2 receptors found on blood vessel linings. By entering these cells, the virus can cause vascular dysfunction and speed up arterial ageing. Our immune and inflammatory responses, which normally protect against infection, may also contribute to this damage.”

Covid Could Be Causing Women To Age Faster

Discussing the sex differences, she added: “Women generally mount a faster, stronger immune response, which helps defend against the infection. However, this same response can sometimes increase damage to the blood vessels after the virus has passed.”

The study found that Covid’s impact extends far beyond the respiratory system, silently affecting blood vessels and accelerating vascular aging, especially in women. While vaccination appears to offer some protection, awareness and early monitoring of heart health are important.

Over 140,000 bottles of a prescription statin have been pulled from the market due to “failed dissolution specifications,” according to a report by the U.S. Food and Drug Administration (FDA). Ascend Laboratories, based in New Jersey, recalled Atorvastatin Calcium, a generic version of Lipitor, manufactured by Alkem Laboratories of India and distributed across the country. The recall covers tablets in 90-count, 500-count, and 1,000-count bottles with expiration dates extending to February 2027.

Atorvastatin Recall: Why Is The Popular Cholesterol Medicine Being Recalled?

On October 10, 2025, the FDA classified the recalled drug as a Class II recall. This classification means the medication could cause “temporary or medically reversible adverse health effects,” though the likelihood of serious harm is considered “remote.”

Statins are widely prescribed to manage high cholesterol and to prevent or reduce heart disease, according to a 2023 study from Florida Agricultural and Mechanical University.

Dr. Tamanna Singh of the Cleveland Clinic noted on a September podcast that roughly “39 million adult Americans” take statins, with the largest group being over 40. She added that Lipitor, Crestor, and their generics, atorvastatin and rosuvastatin, are the most commonly prescribed medications in this class.

Atorvastatin Recall: Why This Cholesterol-Lowering Drug Recall Matters

Most drug recalls are initiated by the manufacturers themselves, and this appears to be the case here. The recalled product is made by New Jersey-based Biocon Pharma, Inc. “Recalls are typically initiated voluntarily by companies before they notify the FDA,” explained Dr. Ileana Elder, Branch Chief in the Incidents, Recalls, and Shortages Branch at the FDA’s Center for Drug Evaluation and Research, in a 2024 Q&A.

Atorvastatin Recall: What Should People Do With the Recalled Medication?

Neither the FDA nor the companies have issued detailed instructions on handling the recalled tablets. GoodRx advises anyone affected by a recall to check their medication’s lot number, contact their pharmacy, reach out to their prescriber, and properly dispose of the recalled medication.

Statins like atorvastatin are among the most commonly prescribed drugs for lowering “bad” cholesterol and reducing heart disease risk, meaning many adults could be affected. A failure in dissolution means the medication may not deliver the correct dose, which can compromise treatment effectiveness, particularly for those relying on consistent cholesterol control.

The recall being classified as Class II (risk of temporary or reversible harm) highlights that the risk is serious but not immediately life-threatening. Because generic medications are widely used and often more affordable, many patients may not realise their specific bottle is impacted and may continue taking it, assuming it is safe.

Atorvastatin Recall: How to Check if Your Bottle Is Affected

Check your prescription bottles for the manufacturer, lot number, and bottle size listed in the FDA notice.

If your medication is part of the recall, do not stop taking it suddenly—contact your healthcare provider for guidance and request a replacement or alternate formulation. Keep any affected bottles separate, and avoid sharing your medication, as only specific batches have been flagged. Always store your medications correctly, and check with your pharmacy at each refill to ensure the lot and manufacturer are free of recalls.

Iceland, one of the last regions in the world without mosquitoes, has recorded its first sightings of the insects following an unusually warm spring. The discovery was confirmed by the country’s National Science Institute on Monday, October 20, 2025. The sightings come after a record-breaking summer that accelerated glacial melting across Iceland.

Insect enthusiast Bjorn Hjaltason noticed the mosquitoes over several nights last week while observing moths using wine-soaked ropes, local media reported.

When Were Mosquitoes Detected in Iceland?

On October 16, Hjaltason shared on a Facebook group that he had spotted mosquitoes at dusk in Kidafell, Kjos. He captured some using a red wine ribbon, a trap that attracts insects with sweetened wine.

Kjos is a glacial valley about 52 km (32 miles) northeast of Reykjavik, Iceland’s capital. Hjaltason sent his specimens to the Natural Science Institute of Iceland, where entomologist Matthias Alfredsson confirmed they were indeed mosquitoes.

Climate Change Leading To Mosquito Discovery In Iceland

“The recent mosquito sightings in Iceland are likely linked to climate change,” said Carla Vieira, a scientist studying mosquito-borne viruses at QIMR Berghofer Medical Research Institute in Australia, according to The Washington Post. “Rising global temperatures and milder winters create conditions where mosquitoes can survive and reproduce in areas that were previously too cold.”

The Natural Science Institute said it’s unclear how these mosquitoes arrived in Iceland. “It’s possible they were transported via freight,” the institute stated. “Whether they’ve permanently settled here is uncertain, but conditions suggest they could survive.”

A report by Al Jazeera notes that Iceland is warming faster than almost anywhere else. In May 2025, Iceland and neighboring Greenland experienced extreme heat caused by a persistent weather pattern bringing unusually warm air from the south. Temperatures were about 13°C (23.4°F) above the 1990–2020 average, ten times higher than the global average increase of 1.3°C (2.3°F).

Glaciers have been melting rapidly and are projected to lose nearly half their volume by 2100, according to Iceland’s Vatnajokull National Park website.

However, some experts caution against quickly attributing the mosquito discovery to climate change. Alfredsson and epidemiologist Colin J. Carlson from Yale University points out that while climate change may have made the sightings more likely, the full picture of mosquito range shifts remains unclear.

Which Type Of Mosquitoes Have Been Found In Iceland?

Alfredsson identified the species as “Culiseta annulata,” a cold-resistant mosquito native to the Palearctic region, which includes Europe, North Africa, and much of Asia north of the Himalayas. These mosquitoes are not known to carry disease, though they can be bothersome.

“They survive cold climates by hibernating as adults in sheltered spaces like basements or outbuildings,” the Natural Science Institute said. “They bite but are not considered dangerous to humans in these regions, as they carry no known infections. Mosquito species adapted to cooler climates generally don’t transmit diseases.”

Can Mosquitoes Survive In Iceland?

It is not known yet whether these mosquitoes will establish permanent populations in Iceland. Philip Weinstein, an infectious diseases researcher at the University of Adelaide, believes Iceland’s harsh winters may be too challenging, even for a cold-adapted species. On the other hand, Gisli Gislason, professor emeritus of limnology at the University of Iceland, thinks the mosquitoes may settle in.

Further monitoring will be needed to determine the outcome. If these mosquitoes do establish themselves, only Antarctica would remain free of the pesky insects.
