Experiencing daytime sleepiness is something that is usually perceived as a minor inconvenience, but for older adults, it could be an early warning sign of Dementia. This neurodegenerative disease leads to the progressive decline of brain cells. This eventually

affects memory, cognition, and personality, making everyday tasks more difficult. As one of the fastest-growing neurological disorders across the world, dementia poses a significant health threat to ageing populations.

Is Dementia Linked To Poor Sleep?

For this study, researchers followed 445 older adults (average age 76) over three years, aiming to determine whether poor sleep could increase the risk of mild cognitive impairment (MCI), which often leads to dementia. At the start, none of the participants had MCI, but by the end of the study, 36 individuals had developed the condition.

The researchers discovered that participants with poor sleep were more likely to develop MCI compared to those who slept well. However, when depression symptoms were taken into account, the link between poor sleep and MCI became less pronounced, suggesting that while sleep issues are a concern, mental health also plays a key role in dementia risk.

To assess sleep quality, the Pittsburgh Sleep Quality Index (PSQI) was used, evaluating factors such as sleep duration, disturbances, and daytime alertness. Among these, "daytime dysfunction"—defined as excessive sleepiness and low energy during the day—was most strongly associated with an increased risk of MCI. Those experiencing daytime dysfunction were more than three times as likely to develop MCI as those who didn’t report such symptoms.

There are many types of dementia:

Dementia is not a specific disease. According to the Centers for Disease Control and Prevention (CDC), it is an overall term that describes a decline in mental ability that interferes with daily life. People with dementia often have symptoms like trouble remembering, thinking, or making everyday decisions. These symptoms tend to get worse over time.

Alzheimer’s disease is the most common type of dementia, and it mostly affects the elderly. Each form of dementia has a different cause. Though dementia mostly affects older adults, it is not a part of normal ageing. An estimated 6.7 million older adults have Alzheimer's disease in the United States. That number is expected to double by 2060, as per data from the CDC.

In 2022, 3.8% of men and 4.2% women in US were diagnosed with dementia. The percentage of people increase with age from 1.7% for those aged 65-74 to 13.1% for those aged 85 and older. Alzheimer's accounts for 60 to 80% of all dementia cases and it is most prevalent in California, Florida, and Texas, as these states have the highest number of people.

After recalling lettuce that may have been linked to a severe nationwide Cyclospora outbreak in the US, Taylor Farms has now recalled 20 more products, including salsa and guacamole, over concerns about possible Salmonella contamination.

Taylor Farms also said on social media that none of its Taylor Farms-branded salad kits are associated with the outbreak. Most of the recalled lettuce was sold in large bags to food-service operations, including restaurants, with many products containing romaine lettuce.

Why Has Taylor Farms Issued Another Recall?

In a statement on August 9, Taylor Farms said the latest recall is tied to fresh jalapeños supplied by Coast Citrus Distributors. A grower in Sinaloa, Mexico, that supplies Coast Citrus was identified as a potential source of the Salmonella outbreak.

“Taylor Fresh Foods is no longer sourcing products from this farmer and will be filling orders from alternative suppliers,” the company said on its website.

Where Were the Recalled Products Sold?

The recalled products were sold in several states, including Texas, and distributed to major retailers such as Target, Walmart and Whole Foods.

Taylor Farms products were also recalled from Target, Trader Joe’s and Scarborough, Maine-based supermarket chain Hannaford across about 20 states.

Walmart said it had removed the impacted products from its stores and implemented a sales block at its registers and online. Kroger, Target, Whole Foods, Trader Joe’s and Hannaford-parent Ahold Delhaize did not immediately respond to a Reuters request for comment.

Salmonella Outbreak Linked to Jalapeños

The CDC and FDA said earlier this week that they were investigating a Salmonella outbreak that had sickened 345 people across 27 states and led to 36 hospitalizations.

The US investigation identified restaurants including Chipotle Mexican Grill and Qdoba as having received jalapeños imported by Coast Citrus Distributors, Reuters reported.

Both restaurants stopped using the jalapeños, while Coast Citrus recalled the remaining product and notified customers.

USDA Issues Alert for Meat and Poultry Products

The US Department of Agriculture (USDA) has also issued a new public health alert for 18 meat and poultry products containing recalled jalapeño peppers potentially contaminated with Salmonella.

The products were made using jalapeños that had already been recalled by the FDA. Many of the affected products are sold under brands including Taylor Farms, Walmart’s Marketside and H-E-B. The products have expiry dates extending through August 15.

The USDA’s Food Safety and Inspection Service (FSIS) said the issue came to light after the FDA notified the agency that several meat and poultry establishments had received the recalled jalapeños as an ingredient.

The agency warned that some of the products may still be sitting in consumers’ refrigerators or freezers and advised people not to eat them. Retailers have also been told not to sell the affected products.

What Are the Symptoms of Salmonella?

Young children, older adults and people with weakened immune systems are at greater risk of developing severe illness.

Contaminated food may look, smell and taste completely normal, meaning consumers cannot rely on appearance or taste to determine whether food is safe.

Consumers who have purchased products covered by the USDA alert should not eat them. They should discard them safely or return them to the place of purchase.

Anyone who develops symptoms after eating a potentially contaminated product should contact a healthcare provider and disclose the possible Salmonella exposure.

Frequent cannabis use is sending more people to emergency rooms with episodes of severe nausea, uncontrollable vomiting and abdominal pain, according to a new report from the US Centers for Disease Control and Prevention (CDC).

The study also observed that teenagers and young adults are among the groups that were most affected with these symptoms.

The study, published August 6 in the CDC’s Morbidity and Mortality Weekly Report (MMWR), analysed emergency department data from January 2023 through May 2026. Researchers identified 199,565 emergency visits involving cannabis hyperemesis syndrome (CHS) during that period.

CHS is a condition linked with frequent, prolonged cannabis use. It can cause repeated episodes of intense nausea, vomiting and abdominal pain. In severe cases, repeated vomiting can result in dehydration and other related complications.

Why Are The Cases Rising Among Young Population?

A new diagnosis code specifically for CHS was introduced in the US on October 1, 2025. Before that, doctors often had to identify CHS by combining codes for vomiting with codes indicating cannabis use.

It meant that several cases were missed or dismissed and diagnosed as another gastrointestinal problem.

After the new code was introduced, CHS-related emergency visits jumped from 3.35 per 10,000 emergency visits in September 2025 to 11.26 per 10,000 in October.

Between October 2025 and May 2026, the average monthly proportion was 3.7 times higher than the monthly average recorded before the new code was introduced.

CDC researchers, however, caution that this does not necessarily mean CHS itself suddenly became 3.7 times more common. Better recognition and reporting most likely can explain the increase. The researchers wrote that “the abrupt, sustained increase” may be due to better recognition and testing.

The highest proportion of CHS-related emergency visits was seen among younger patients between the age of 15–24 years.

Among visits recorded after the new diagnostic code was introduced, this age group accounted for an average of 38.70 CHS-involved visits per 10,000 emergency visits, compared with 28.28 among people aged 25–34. The number of females were also higher than males.

Researchers added that this pattern could also be due to earlier use of cannabis use combined with frequent consumption of THC products.

Warning Signs

CHS typically causes nausea, uncontrollable vomiting and severe abdominal pain.

A few patients reported temporary relief from very hot showers or baths.

The condition can be difficult to recognise because its symptoms overlap with other causes of vomiting.

The researchers also say that CHS can occur sooner after cannabis use than previously thought and may remain undiagnosed for years.

Stopping cannabis use completely is considered the key step in preventing repeated episodes of CHS.

A harmless day at the beach may come with an unexpected health risk this summer as Louisiana health officials have warned residents and beachgoers about an increase in infections caused by Vibrio vulnificus, a deadly bacterium that is found in warm coastal and brackish waters.

Louisiana has reported nine Vibrio vulnificus infections so far in 2026. According to the Louisiana Department of Health, five among nine patients who were hospitalized died.

During the same period over the previous decade, the state saw about seven cases and one death.

The warning comes as Gulf Coast waters can get warmer, creating conditions in which Vibrio can thrive.

If bacteria enter through a cut or other break in the skin, you may contract an infection. Vibrio vulnificus naturally occurs in warm saltwater and brackish water, where fresh and saltwater mix.

A swimmer with an open wound, scrape, recent piercing, tattoo or surgical incision can become infected when the wound comes into contact with contaminated water.

The bacteria can also cause infection after someone eats raw or undercooked shellfish, specially oysters.

The term 'flesh-eating bacteria' sounds straight out of a zombie horror film, but there is a scientific reason behind the nickname.

Vibrio vulnificus can cause severe wound infections and, in some cases, necrotizing fasciitis, a rapidly progressing infection that destroys tissue.

Why Is Vibrio Dangerous?

The infection is uncommon, but it can become severe pretty quickly. The CDC estimates that roughly one in five people with Vibrio vulnificus infection die, although the risk varies depending on the illness, delay in treatment and the patient’s health.

People with liver disease, diabetes, weakened immunity and certain chronic illnesses are particularly vulnerable to this infection. Older adults are also at higher risk.

Louisiana state epidemiologist Theresa Sokol has previously warned that the bacteria can progress rapidly.

“If you have a wound, that’s when you really need to try to stay out of the salt or brackish water,” Sokol said.

How To Protect Yourself?

An infected wound may initially turn red, swollen, painful or warm. Discoloration, blistering, fever and chills may indicate a more serious infection.

Louisiana health officials advise seeking medical care immediately if a wound exposed to salt or brackish water develops these symptoms and telling the healthcare provider about the water exposure.

The CDC recommends:

• Avoid swimming or wading in saltwater or brackish water if you have an open wound.
• Cover wounds with a waterproof bandage if exposure is unavoidable.
• Wash wounds thoroughly with soap and clean running water after contact with coastal water.
• Avoid raw or undercooked shellfish, particularly oysters.
• Seek medical attention quickly if infection symptoms appear after exposure or wounds change rapidly.

A 2026 study published in Applied and Environmental Microbiology also found substantial seasonal Vibrio concentrations in southeast Louisiana recreational waters, with the highest average concentrations during June, July and August.

For most healthy beachgoers, this is not a reason to cancel summer plans. But anyone with an open wound or underlying health condition, should keep the wound out of waters, and don’t ignore a rapidly changing wound after exposure.
