Have you ever wondered why some people who drink alcohol develop serious liver problems while others don’t? A study from University of Louisville researchers published in May in Toxicological Sciences suggests that the answer might be hidden in everyday sources such as drinking water, food packaging or even non-stick cookware.
Scientists at UofL, along with colleagues from Boston University and the University of Massachusetts Lowell, have identified perfluorooctane sulfonate (PFOS) as a potential environmental factor that worsens alcohol-associated liver disease.
PFOS is a man-made chemical belonging to the group known as per- and polyfluoroalkyl substances (PFAS), often referred to as “forever chemicals” because they do not readily break down in the environment or the human body. These substances have been used for decades in products such as non-stick cookware, water-resistant clothing, fast-food packaging, stain-resistant carpets and upholstery, and firefighting foams. Their extensive use has led to widespread contamination in the environment. Recent data from National Health and Nutrition Examination Survey show that PFAS can be detected in approximately 95% of Americans, sparking increasing concern about their long-term health effects.
At the same time, alcohol consumption remains a significant global health issue. According to the World Health Organization, alcohol contributes to nearly 3 million deaths worldwide each year, and its consumption continues to rise globally. In the U.S. alone, excessive alcohol use is responsible for approximately 95,000 deaths annually, making it one of the leading causes of preventable death and a major contributor to liver disease.
“Given the increasing prevalence of alcohol consumption and the widespread presence of PFAS in the environment, many individuals who drink alcohol may be inevitably exposed to these persistent pollutants. This makes it critically important to study how combined exposures to alcohol and environmental chemicals like PFOS might influence liver health,” said Matthew Cave, UofL professor of medicine and publication co-author.
Although it is well known that both alcohol and PFOS cause liver damage individually, little has been understood about their combined effects until now. Recent studies have shown that only about 35% of heavy drinkers develop severe forms of liver disease, indicating that additional factors such as genetics, sex, microbiome and environmental exposures may contribute to individual susceptibility.
“This work helps explain why two people with similar alcohol consumption may experience very different liver outcomes,” said Frederick Ekuban, assistant professor of medicine at UofL and first author of the study. “Environmental exposures like PFOS may be the missing link.”
Using animal models, the researchers simulated real-world exposures to both alcohol and PFOS. The study showed that co-exposure to alcohol and PFOS significantly increased fat accumulation and markers of liver damage, as well as clear signs of disrupted metabolism and activation of genes and pathways predicted to be associated with oxidative stress and cancer development.
In short, the study demonstrates that PFOS exposure can significantly worsen liver damage when combined with alcohol consumption. While this research used high levels of alcohol to understand the underlying mechanisms, the findings reveal important biological pathways that warrant further investigation across different drinking patterns.
The research team also found that PFOS interferes with the liver’s ability to manage fats, disrupts its natural protective and repair systems and activates pathways that promote liver injury.
“While the liver typically has a remarkable capacity to recover from alcohol-induced stress, PFOS appears to push that resilience beyond its limits, resulting in compounded and more severe damage,” said Jennifer Schlezinger professor of environmental health at Boston University and co-author of the publication.
Perhaps most concerning, the team discovered that 60% of all PFOS exposure ended up concentrated in the liver, exactly where alcohol damage occurs.
Ongoing research at UofL is examining how other PFAS compounds may interact with alcohol, whether males and females respond differently to these exposures and what the long-term consequences of combined exposures might be. The team is also exploring whether targeted therapies can be developed to prevent or mitigate this type of liver damage.
Although more studies are needed, people can take practical steps now to limit their exposure to PFAS. These include:
Choose stainless steel or cast-iron cookware instead of non-stick pans
Use water filters, especially in areas near industrial zones
Avoid stain-resistant treatments on furniture and carpets
Reduce consumption of packaged fast foods and microwave popcorn.
Select household products with PFAS-free labels
Given that liver disease affects millions of Americans and is becoming more prevalent worldwide, the findings of this research support growing calls for stronger regulation and oversight of persistent chemical contaminants. By better understanding the hidden interactions between environmental toxicants and lifestyle behaviors, scientists and policymakers may be better equipped to prevent and treat liver disease.
Opioids like morphine are widely used in medical practice due to their powerful pain-relieving effects. However, they carry the risk of serious adverse effects such as respiratory depression and drug dependence. For this reason, Japan has strict regulations in place to ensure that these medications are prescribed only by authorized physicians.
In the United States, however, the opioid OxyContin was once prescribed frequently triggering a surge in the misuse of synthetic opioids such as fentanyl. As a result, the number of deaths caused by opioid overdose surpassed 80,000 in 2023, escalating into a national public health crisis now referred to as the “opioid crisis”.
Opioids may soon have a rival, however. A team of researchers at Kyoto University has recently discovered a novel analgesic, or pain reliever, which exerts its effect through an entirely different mechanism. Clinical development of their drug ADRIANA is currently underway as part of an international collaborative effort.
“If successfully commercialized, ADRIANA would offer a new pain management option that does not rely on opioids, contributing significantly to the reduction of opioid use in clinical settings,” says corresponding author Masatoshi Hagiwara, a specially-appointed professor at Kyoto University.
The research team was first inspired by substances that mimic noradrenaline, which is released in life-threatening situations andactivates α2A-adrenoceptors to suppress pain. However, these pose a high risk of cardiovascular instability. After observing noradrenaline levels and α2B-adrenoceptors, the team hypothesized that selectively blocking α2B-adrenoceptors could elevate noradrenaline levels, leading to activation of α2A-adrenoceptors and resulting in pain relief without causing cardiovascular instability.
To identify selective inhibitors of α2B-adrenoceptors and measure the activity of individual α2-adrenoceptor subtypes, the researchers employed a novel technology known as the TGFα shedding assay and conducted compound screening leading to their discovery of the world’s first selective α2B-adrenoceptor antagonist.
After success in administering the compound to mice and conducting non-clinical studies to assess its safety, physician-led clinical trials were conducted at Kyoto University Hospital. Both the Phase I trial in healthy volunteers and the Phase II trial in patients with postoperative pain following lung cancer surgery yielded highly promising results.
Building on these outcomes, preparations are now underway for a large-scale Phase II clinical trial in the United States, in collaboration with BTB Therapeutics, Inc, a Kyoto University-originated venture company.
As Japan’s first non-opioid analgesic, ADRIANA has the potential not only to relieve severe pain for patients worldwide but could also play a meaningful role in addressing the opioid crisis — a pressing social issue in the United States — and thus contribute to international public health efforts.
“We aim to evaluate the analgesic effects of ADRIANA across various types of pain and ultimately make this treatment accessible to a broader population of patients suffering from chronic pain,” says Hagiwara.
The stress preterm infants experience at birth can carry on throughout a lifetime and cause negative health impacts later in life, necessitating the routine inclusion of birth history in medical records and the development of clinical guidelines for adults born preterm, the longest continuously running study of individuals born preterm in the United States has shown.
University of Rhode Island College of Nursing Professor Amy D’Agata is continuing the work that began in the 1980s with a group of babies born preterm at Women & Infants Hospital. Involving 215 people born 35 years ago-including a control group of full-term babies, and preterm babies born at 22 to 36 weeks-the study tracks the successes and difficulties preterm babies continue to face into adulthood, and compares them to the group of participants born full term. The project has so far garnered more than $10 million in research grant funding.
D’Agata, who took over as principal researcher after the retirement of Professor Emeritus Mary Sullivan, has published the most recent results in the Journal of the American Medical Association. The published paper focuses physiological and psychological health outcomes that D’Agata and her team of researchers have identified as the study participants approach 40 years old. Those born preterm have shown a higher risk of high blood pressure, high cholesterol, increased abdominal fat, and low bone density. Psychologically, the group tends to internalize problems, often resulting in increased levels of depression and anxiety.
“Preterm birth is not just a neonatal issue. It, in fact, is a lifelong condition,” D’Agata said the study shows. “For individuals who have medical complications early in life, we are now seeing an increased risk of different chronic health issues later in life. We are now realizing that there is a very strong link between what happens to you early in life and later health outcomes.”
The study offers important takeaways for health-care clinicians, who are not always aware a patient was born preterm because birth history is not commonly included in adult medical records. D’Agata’s study is showing the need to include the information, and to develop adult screening guidelines for individuals who have a history of preterm birth. The work is also helping people who have been impacted by preterm birth understand that their birth history should be included in their medical records and should be considered in the context of their overall health.
In this country, millions of people born preterm have grown into adulthood and are now seeing clinicians across primary care and various specialties, yet providers rarely ask about birth history. We are urging that birth history be included as a standard question on every adult intake form. Health cannot be fully optimized if we overlook such a critical assessment piece. Understanding an individual’s birth history, alongside growing research identifying increased health risks for those born preterm and the development of targeted clinical guidelines, will advance health equity for survivors of early birth. We believe a paradigm shift is needed in health care that recognizes preterm birth as a chronic condition requiring lifelong monitoring and support.”
Amy D’Agata, University of Rhode Island College of Nursing Professor
While the study’s most recent results were just published in JAMA Network Open in July, D’Agata is already looking toward the next set of findings. Continuing to work with fellow URI professor Justin Parent, D’Agata is examining epigenetic age acceleration among individuals born preterm. Understanding any differences in epigenetic aging that may exist between preterm and full-term born adults may be another approach to understanding long-term health.

When faced with difficult tasks, sometimes people hit a mental wall and make the decision to “sleep on it.” Returning to the task after sleeping, they often perform better. Why? Rhythmic brain activity during sleep transforms task-related information into stronger, longer-term memory. A new JNeurosci paper on research led by Dara Manoach, from Harvard Medical School, advances understanding of where in the brain this rhythmic activity appears to improve motor learning.
In the study, 25 participants learned a typing sequence while the researchers recorded their brain activity. After training, brain recordings continued as study participants napped. During sleep, cortical brain areas active during training had more rhythmic activity. Increased brain rhythms in these areas correlated with how much participants improved in the task after the nap. Notably, pre- and postnap task performance had different neural correlates; learning during training was associated with increased brain rhythms in movement execution areas during sleep, while postnap performance was linked to increased brain rhythms in movement planning areas during sleep. Says Manoach, “Brain rhythms occur everywhere in the brain during sleep. But the rhythms in these regions increase after learning, presumably to stabilize and enhance memory.”
The researchers theorize from their work that brain rhythms in motor execution areas may represent the memory of a task, while the rhythms in motor planning areas improve future performance.

Temporomandibular disorder (TMD) limits jaw function and is so painful that it lessens the quality of life. Botulinum toxin-also known as botox-is emerging as an effective treatment option, but there are concerns about side effects, like muscle dysfunction. Eungyung Kim and Yu Shin Kim, from the University of Texas Health Science Center at San Antonio, led a study using a mouse model of TMD to explore the possibility of using botox as a treatment.
In their JNeurosci paper, the researchers discovered that injecting botox directly into the male mouse temporomandibular joint (TMJ) instead of surrounding muscle tissue reduced TMD-related pain without causing side effects. More specifically, hypersensitivity and pain from TMD were mitigated without impairing general movement abilities and feeding behavior. The researchers also found that the botox injections they delivered reduced TMD-related neural activity. On a molecular level, mice that received botox injections into the TMJ had less expression of proteins that promote pain.
While sex differences remain unexplored, according to the authors, this work suggests it may be possible to overcome botox side effects by avoiding muscle tissue and injecting the toxin directly into the TMJ.

A Kyoto University research team has developed a pain-reliever that is comparable to morphine but does not have serious side effects.
Morphine, often administered to cancer patients, has serious adverse effects such as breathing issues and addiction.
According to the team, the newly developed drug, Adriana, is a groundbreaking painkiller, which works on a completely different mechanism to morphine and other existing synthetic opioids. The drug has the potential to revolutionize pain control in the medical field, the team said.
The team also expects that the drug will help resolve the so-called opioid epidemic, in which a large number of deaths occur mainly due to overdoses of opioids.
Its findings were published in the online edition of the U.S. journal Proceedings of the National Academy of Sciences.
When a person encounters a life-threatening situation, norepinephrine, an organic chemical secreted from the brain, suppresses pain.
For its study, the team focused on the human body regulating oversecretion of norepinephrine. By introducing a new research technology, the team succeeded in developing a drug blocking such a control function for the first time in the world.
In a clinical trial conducted at the Kyoto University Hospital between January 2023 and December 2024, the team confirmed the new drug’s efficiency to a certain extent for patients including 20 who underwent lung cancer surgery.
The team plans to conduct a clinical trial in the United States for 400 postsurgery patients in 2026, aiming to put Adriana into practical use in 2028.
“We hope that the new drug will help cancer patients who previously had no choice but to use opioids live their lives without pain as well as a need to worry about addiction or serious side effects,” Masatoshi Hagiwara, a professor at the university, said.

Vibrio vulnificus is a life-threatening marine bacterium, increasingly linked to seafood consumption and wound infections, especially in vulnerable people. Its geographic range and public health impact are growing due to climate and environmental change.
Vibrio species, particularly Vibrio vulnificus, are increasingly recognized as important and sometimes severe public-health hazards capable of causing rapid septicemia, gastroenteritis, and necrotizing wound infections. Climate‑driven proliferation and dietary habits have converged to increase the incidence of vibriosis and related septic shock among high-risk individuals in coastal communities throughout the world.1
Taxonomy and ecology
Vibrio vulnificus is a Gram‑negative halophilic member of the family Vibrionaceae that thrives in warm, low‑salinity estuaries where tidal mixing concentrates organic matter. The curved rods of Vibrio vulnificus are routinely recovered from brackish coastal waters and bio‑accumulated by filter‑feeding shellfish. In particular, the eastern oyster (Crassostrea virginica) acts as both an environmental reservoir and a vehicle for human exposure.

Nutrient‑rich runoff, suspended particulates, and other anthropogenic inputs further contribute to Vibrio vulnificus proliferation by supplying carbon nutrients and attachment surfaces. The organism is rarely detected in waters below 15 °C and is most abundant above 20 °C. Taken together, temperature, salinity, and nutrient availability interact synergistically to modulate the ecology and health risk of this opportunistic pathogen.2
Virulence factors and pathogenic mechanisms
Vibrio vulnificus invades hosts with a multi-layered arsenal. A surface capsular polysaccharide (CPS) masks complement fragments to avoid macrophage engulfment, thereby protecting the bacterium from serum killing.3
Secreted pore‑forming toxins, led by Vibrio vulnificus hemolysin A (VvhA), rupture cell membranes, precipitate dermal necrosis, and induce a cytokine storm that can eventually progress to septic shock. Other virulence determinants include the metalloprotease VvpE, multifunctional RTX toxins, and additional outer-membrane proteins that contribute to tissue invasion and immune evasion. Importantly, systemic dissemination is dependent upon iron levels, as the catechol siderophore vulnibactin and its outer‑membrane receptor obtain iron from transferrin and lactoferrin to ensure bloodstream proliferation.3
In estuarine niches, high levels of cyclic di‑guanosine monophosphate (c‑di‑GMP) and type IV pili contribute to the development of biofilm matrices that shield cells between hosts. Expression of these traits is determined by autoinducer‑2 synthase LuxS and small colony regulator (SmcR) quorum‑sensing circuitry, as mutants lacking either regulator exhibit significantly reduced cytotoxicity and require higher inocula to cause lethal disease.3
Routes of infection and disease manifestations
Vibrio vulnificus infects humans through ingestion or percutaneous exposure. For example, ingestion of raw or undercooked shellfish, especially oysters, deposits high bacterial loads into the gastrointestinal tract.
In most healthy people, this leads to a brief gastroenteritis characterized by diarrhea, cramps, and vomiting. Importantly, Vibrio vulnificus can cross the intestinal barrier to reach the bloodstream, which leads to primary septicemia (PS) with a fatality rate of up to 60%. However, bloodstream infection develops primarily in immunocompromised or chronically ill patients, and the overall incidence of septicemia is low among healthy adults.
Percutaneous exposure to seawater or seafood contaminated with Vibrio vulnificus can lead to infection by entering the bloodstream through an open wound. Local infection begins with painful swelling and hemorrhagic bullae that can progress within hours to necrotizing fasciitis, sometimes necessitating amputation.4
Patients diagnosed with chronic liver disease, diabetes mellitus, malignancy, renal dysfunction, acquired immunodeficiency syndrome (AIDS), or other forms of immunosuppression are at a significantly greater risk of fulminant PS due to their compromised innate defenses that allow bacterial growth.
Risk of Vibrio vulnificus infection is particularly high during warm summer and autumn when bacterial replication accelerates. As a result, seafood handlers, swimmers, and coastal residents are advised to avoid consuming raw shellfish, promptly disinfect cuts, and seek urgent care for spreading limb pain. Early culture‑guided antibiotics and, when indicated, aggressive surgical debridement remain vital to survival and intensive support.4

Diagnosis and treatment
Timely recognition of Vibrio vulnificus infection is based on microbiological confirmation, following which immediate and aggressive management is essential. Blood and wound samples, including blister fluid, should be cultured on thiosulfate‑citrate‑bile‑salts‑sucrose agar.
Gram stain of the specimen often reveals banana‑shaped Gram‑negative rods. Since conventional culturing requires up to 48 hours to complete, polymerase chain reaction (PCR) or matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) methods are frequently used to identify the pathogen within hours to accurately guide therapy.
Any broad‑spectrum agent active against Gram‑negative bacilli can be used to treat Vibrio vulnificus. However, doxycycline combined with a third‑generation cephalosporin (such as ceftriaxone or ceftazidime) is widely recommended due to the organism’s rapid doubling time. Fluoroquinolones are an alternative. Imaging is often used to determine a diagnosis of gas gangrene, whereas laboratory tests screen for coagulopathy, hepatic, or renal dysfunction.5
Debridement of devitalized tissue under general anesthesia should begin as soon as feasible after diagnosis. Primary limb amputation is advised if the fascia and muscle are overtly necrotic or the haemodynamic status deteriorates. Throughout resuscitation, clinicians will prioritize circulatory stabilization and support in an intensive care setting to prevent or reverse septic shock and multiorgan failure.5
Epidemiology and risk factors
Vibrio vulnificus thrives in warm, brackish seas and can be found along many temperate‑to‑tropical shorelines. In the United States, these infections have primarily been reported along the Gulf of Mexico; however, Vibrio vulnificus has also been detected along the Atlantic and Pacific coasts, Hawaii, and, occasionally, inland after storm flooding.
In East Asia, especially Japan and China, Vibrio vulnificus prevalence in seafood often exceeds 30%, which is significantly greater than its levels in West Asian waters. Peak reporting occurs between May and October, a period marked by high sea‑surface temperatures of 20-25 °C and high levels of bacterial contamination.6,7
Host factors often determine infection outcomes, as adults with alcoholic cirrhosis are 80-and 200-times more likely to become infected and die after eating raw oysters than healthy diners, respectively. The 80-fold risk refers to infection, and the 200-fold risk to mortality. Other high‑risk groups include people diagnosed with hemochromatosis, thalassemia major, diabetes mellitus, chronic kidney disease, or medication‑induced immunosuppression.6,7
As oceans warm, fisheries and recreational waters deliver Vibrio vulnificus to new latitudes where seafood supply chains and coastal wounds facilitate its circulation. These converging environmental and host factors lead to summertime surges of fulminant septicemia and necrotizing wound infections that have been increasingly reported from the Gulf Coast to East Asia and other warming estuaries throughout the world.6,7
Public health challenges
Surveillance efforts for Vibrio vulnificus are primarily concentrated in the United States and Europe. Comparatively, low‑income countries lack routine testing, which leads to the under‑reporting of cases and weaker risk models.
Climate change is also transporting the bacterium into waters once considered safe. For example, heat‑driven blooms have pushed infections as far north as sub‑Arctic Finland and expanded suitable coastlines by about 392 km² since 1982.
Raw seafood, particularly filter‑feeding oysters, can concentrate Vibrio vulnificus, thereby serving as a potent vehicle for infection. Economically, fulminant septicemia and necrotizing fasciitis often demand prolonged intensive care unit (ICU) management, which makes Vibrio vulnificus one of the most expensive marine‑borne pathogens per case, with an estimated annual burden valued at over $267 million USD.8
New study find cases of flesh eating bacteria may rise
Prevention strategies
Vulnerable patient populations are advised to avoid raw or under‑cooked shellfish altogether to reduce their risk of infection. Cooking shellfish thoroughly to an internal temperature of at least 63 °C (145 °F) effectively kills Vibrio species. Individuals with open wounds, recent piercings, or tattoos must ensure that these areas remain dry and protected while swimming, wading, or handling seafood to prevent bacterial entry.
Federal regulators are expected to perform continuous water‑quality monitoring and impose prompt harvesting closures in the event that water temperature, salinity, or bacterial counts exceed safety limits. Sustained public health campaigns in coastal and endemic areas should teach safe seafood practices, wound care, and early symptom recognition.9 Note: Reference 9 primarily addresses prevention in aquaculture; for human public health, guidance is available from CDC and WHO sources.
Conclusions
Rising sea‑surface temperatures, altered salinity, and nutrient‑rich runoff are expanding the ecological range of Vibrio vulnificus, thereby increasing the risk of infection outside of traditional Gulf Coast and East Asian hotspots.
Protecting public health requires coordinated action across healthcare, environmental monitoring, aquaculture, and food‑safety sectors. These efforts must incorporate routine coastal surveillance, rapid detection technologies, stricter shellfish harvest controls, climate‑informed warning systems, and ongoing community education to ensure the early detection and mitigation of future outbreaks.

In a significant achievement for public health and animal welfare, the number of rabies-infected stray dogs in the city has dropped sharply over the past few years, according to data released by the Pune Municipal Corporation (PMC)’s Health department.
While 373 suspected rabies cases were reported in 2018, only 19 cases have been recorded so far in 2025. Similarly, confirmed rabies cases reduced from 220 in 2018 to just 3 in the current year. (REPRESENTATIVE PIC)
The data from 2018 till August 4, 2025 show a decline in the number of suspected as well as confirmed rabies cases. While 373 suspected rabies cases were reported in 2018, only 19 cases have been recorded so far in 2025. Similarly, confirmed rabies cases reduced from 220 in 2018 to just 3 in the current year.
Health officials from the civic body confirmed that the overall positivity rate – the percentage of suspected dogs that tested positive for rabies – has also decreased. The positivity rate was as high as 75% in 2020 and 2021, but has dropped to 15% in 2025.
Dr Sarika Funde-Bhosale, chief veterinary officer, PMC, attributed this decline to the mass vaccination campaigns, awareness drives, and better coordination and implementation of the Animal Birth Control Programme (ABC) in the city.
“Over the past four years, we have successfully administered 191,466 doses of vaccination to stray dogs and community dogs,” she said.
According to civic officials, in case a dog is suspected of carrying rabies, based on symptoms or the type of biting incident reported, it is picked up by the PMC dog squad and admitted to the quarantine facility at the dog pound. The dog is observed and tested for infection, and if found uninfected, is released back in the locality from where it was picked up.
In case of death, the carcass is sent for tests, wherein the brain tissue is tested twice through rapid antigen test and PCR (polymerase chain reaction) test. In the event of rabies-positive cases, mass vaccination drives and community awareness is conducted by the civic body as an immediate follow-up measure.
“Our vaccination drives have not just led to a significant reduction in rabies cases, but have also led to a marked increase in public awareness about reporting dog bites and seeking timely prophylaxis,” said Dr Funde-Bhosale.

Guangdong province has made progress in curbing the spread of Chikungunya fever, particularly in the city of Foshan, where a recent surge in cases has shown signs of slowing, a senior provincial disease control official said.
Kang Min, director of the institute for prevention and control of infectious diseases at the Guangdong Provincial Center for Disease Control and Prevention, said 2,892 new local cases were reported in the week ending Saturday, a decrease of 48 cases from the previous week.
In Foshan”s Shunde district, the hardest-hit area, the number of new cases has declined over five consecutive days, Kang said. He added that despite the progress, both Chikungunya and dengue fever remain in their peak seasons.
“Guangdong, with its high volume of international exchanges, continues to face persistent risks of imported cases,” Kang said.
He warned that the ongoing flood season, along with typhoons, heavy rainfall and other weather conditions, have increased mosquito activity — making the next few weeks particularly challenging for disease prevention and control.
Kang urged both government departments and residents to step up efforts to eliminate mosquito breeding grounds through effective, concrete measures.
Chikungunya fever is an acute infectious disease caused by the chikungunya virus and transmitted by infected Aedes mosquitoes, commonly known as spotted mosquitoes. The disease can affect people of all ages, Kang said.
Zhou Huiling, a senior infectious diseases physician at the First People’s Hospital of Foshan, said patients are currently being treated in isolation wards to prevent further transmission.
Patients can be discharged only after testing negative on nucleic acid tests or after receiving hospital treatment for at least a week, she said.
“Most of the current patients have mild symptoms, and by the time of discharge, symptoms are mostly relieved, with only a few reporting lingering mild joint pain,” Zhou said.
She explained that the joint pain is caused by the virus directly invading joints, infecting osteoblasts and synovial tissues, and triggering the release of pro-inflammatory cytokines that can lead to bone damage.
The pain typically affects small joints in the ankles, fingers and wrists, but can also extend to larger joints such as the knees and shoulders. Symptoms tend to worsen with physical activity, and Zhou advised patients in the acute phase to stay in bed and limit movement.
“Being bitten by a mosquito doesn’t necessarily lead to infection — only bites from virus-carrying mosquitoes pose a risk,” she said.
Although no serious cases have been reported, experts warn that high-risk groups include infants, seniors over age 65, pregnant women, patients with chronic illnesses and those on immunosuppressive treatments, such as organ transplant recipients, AIDS patients and long-term users of immunosuppressants.
“There is still no vaccine available. Mosquito prevention remains the most important control measure, and early screening and isolation are key to preventing community transmission,” Zhou said.

Dietitians recommend supplements like omega-3 fatty acids and soy protein to reduce your cholesterol.
Experts also recommend talking with your provider about plant sterols and psyllium husks.
Other lifestyle changes, like quitting smoking and reducing saturated fat in your diet, can help.
High cholesterol affects about 10% of adults living in the U.S., but experts estimate that many more have high cholesterol levels and have no idea. High cholesterol is silent—the only way to tell if you have elevated numbers ( ≥240 mg/dL of total cholesterol) is by getting a simple blood test. It’s important to know if your cholesterol is high because hypercholesterolemia increases your risk for other conditions, like atherosclerosis, or the buildup of plaque in your arteries that can lead to a heart attack and/or stroke. While there are certain risk factors, like your age and genetics, that you can’t control, there are other factors, like your diet and lifestyle, that you can.
Focusing on nutrient-dense foods like whole grains, fruits and vegetables, in addition to moving more, should be the first line of defense in helping manage high cholesterol levels. But there are science-supported supplements that may also lend support in managing your cholesterol levels. Lauren Manaker, M.S., RDN, LDN, CLEC, shares, “A balanced diet is the foundation for managing cholesterol, while supplements act as a helpful safety net to fill in any gaps.”
Registered dietitians agree that these four supplements may be worth considering if you’ve done everything you can to manage your cholesterol levels and still aren’t seeing the numbers you’d like.
Omega-3s DHA + EPA
DHA, docosahexaenoic acid, and EPA, eicosapentaenoic acid, are two omega-3 fatty acids that continue to top the charts as one of the most recommended supplements for better heart health—and for good reason. A meta-analysis of 90 randomized controlled studies found a dose-response relationship of supplementing with these fats and improved blood lipids. Both DHA and EPA helped lower both triglycerides and non-HDL cholesterol levels. Note, triglycerides aren’t cholesterol; they’re a different lipid. Having high triglycerides means you’re more likely to have high cholesterol, placing you at higher risk for heart disease.
While you can get DHA and EPA through food sources, like salmon, sardines, herring and mackerel, most Americans are falling short on including them in their diet. Enter the supplement safety net. Toby Amidor, M.S., RD, shares, “Most people aren’t getting enough DHA and EPA omega-3 fats. That’s where a supplement can be helpful. In fact, research found that taking more than 2 grams per day of a DHA and EPA combined supplement can help lower blood lipids.”
Plant Sterols
Plant sterols are compounds found in plants that have a similar structure to cholesterol. Because of this, plant sterols can help block cholesterol absorption in the gut, which in turn helps keep blood cholesterol levels in check. Manaker shares, “Plant sterols work by competing with cholesterol for absorption in the digestive system. This means less cholesterol gets absorbed into your bloodstream, which can help lower LDL (“bad”) cholesterol levels without affecting HDL (“good”) cholesterol.”
A meta-analysis explored a variety of nutraceuticals, including plant sterols, and the impact they had on blood lipid levels. While research designs are challenging to do on humans with this particular supplement, the body of research continues to support the inclusion of plant sterols as part of an intervention designed to lower cholesterol levels.
The National Center for Complementary and Integrative Medicine also notes that plant sterol supplements have shown promise in reducing cholesterol levels when taken with meals. While they are overall safe and pose minimal risk, individuals with specific genetic conditions may be at an increased risk of heart disease when the supplement is consumed in excess.
Psyllium Husk
This popular fiber supplement has made a name for itself in weight loss, cholesterol management and blood sugar control. Amidor recommends this supplement for cholesterol management, given its longstanding research in the area. In fact, a review highlights the cholesterol-lowering effects this supplement has on humans. Notably, the soluble fiber in psyllium husk helps lower LDL cholesterol levels through binding to bile acids in the intestines. This helps remove them from the body, which in turn lowers cholesterol levels.
Since there are some downsides to this supplement, like its interaction with other medications and ability to hinder absorption of other nutrients and calories from foods, it’s best to work with your provider to identify the dosage that may be best for you.
Soy Protein
Soy protein has been shown to have a positive impact on cholesterol levels. A systematic review and meta-analysis explored the impact that soy protein supplementation had on postmenopausal women and their cholesterol levels. Scientists found soy protein supplementation demonstrated a significant impact on cholesterol levels, noting a reduction of total cholesterol levels and an increase of HDL cholesterol levels (the “good” cholesterol).
Manaker shares that soy protein’s impact on cholesterol levels is due to its ability to “reduce the liver’s production of cholesterol and increase the clearance of LDL cholesterol from the bloodstream.”
One important point when it comes to soy protein supplementation is that the research shows food sources of soy protein yield better results than a pill form of soy protein, likely due to the other nutrients found in soy products. Manaker recommends considering more tofu, soy milk, edamame and soy protein powders in your diet to start. The good news, too, is that there is little risk associated with consuming more soy protein in your diet (unless you have a soy protein allergy).
Other Strategies to Support Cholesterol Levels
While supplements can be used as a safety net, they are not a replacement for a healthy diet or lifestyle habits that have proven to support cholesterol levels. Amidor and Manaker recommend considering these other strategies to support healthy cholesterol levels:
Limit saturated fat. Saturated fat can raise LDL cholesterol levels, impacting your heart health. The Dietary Guidelines for Americans recommend consuming no more than 10% of your daily calories from saturated fat. To make smarter choices, choose lean and extra-lean cuts of meat and trim visible fat off your meat when preparing it. Reducing consumption of cheese, full-fat dairy and processed meats is also a great way to reduce saturated fat in your diet.
Eat more fruits and vegetables. Filled with fiber and antioxidants, fruits and vegetables help improve diet quality and lower one’s risk of chronic disease. Yet, only 10% of people in the U.S. eat the recommended daily fruits and veggies. Make a conscious effort to add one serving of either a fruit or veggie at every meal and snack.
Enjoy fatty fish (like salmon) twice per week. Up your intakes of those omega-3 fatty acids DHA and EPA by consuming fatty fish at least twice per week. Enlisting the help of canned salmon is an excellent dietitian-approved swap to make mealtime magic happen with these fish.
Choose foods with the American Heart Association’s Heart Check Mark. An easy way to navigate the market is by looking for foods with the heart-check logo. This means items have been vetted by the American Heart Association and have lower fat, sodium and added sugar than other items. But, as with all foods, even a heart-check approved snack food should still be consumed in moderation.
Exercise regularly. Regular movement is an excellent way to improve cholesterol levels and can help manage stress levels (another factor that can indirectly affect your lipid levels). In fact, research shows that moderate and high-intensity movement improves HDL cholesterol levels (the good one). Starting small with a walking routine is a wonderful way to invite more movement into your day.
Quit smoking and vaping, and limit alcohol. Smoking and drinking both increase one’s cholesterol levels. Quitting smoking is a great idea if you have high cholesterol. Alcohol is a known carcinogen and should be reduced. If the thought of giving it up stresses you out more, stick to standard serving sizes when you do enjoy a glass of wine (which is a 5-ounce pour).

Our Expert Take
Nutrition and lifestyle play a critical role in managing high cholesterol levels. But there are four supplements that may offer some benefits, too. For example, nutrition experts recommend adding the omega-3 fatty acids DHA and EPA, as well as soy protein, into your regular routine. Talk with your provider if you want to consider adding psyllium husk or plant sterols as part of your cholesterol-lowering plan.
Working with your individual provider to tailor a plan for you is the best way to ensure you learn how to proactively manage your cholesterol long-term in the way that’s right for you. Other lifestyle changes, such as quitting smoking, limiting alcohol intake, getting regular exercise and reducing saturated fat in your diet, may also benefit your cholesterol levels.
