Heart disease is often linked to high cholesterol, obesity, or lack of exercise. However, there is mounting evidence that suggests that mental health plays a crucial role in cardiovascular well-being. Stress, anxiety, and depression can silently strain the heart, increasing the risk of serious complications.

A recent study, published in Nature Human Behaviour, showed that loneliness has a significant impact on proteins present in a person's blood. For the study, researchers used data from more than 42,000 participants to explore whether the 9.3% who reported social isolation and 6.4% who reported loneliness had different levels of proteins in their blood compared with those who did not. The researchers then studied data that tracked the health of participants over an average 14-year period.

"We found around 90% of these proteins are linked to the risk of mortality," Dr Chun Shen, Fudan University in China, who is also the lead researcher said. "In addition, about 50% of the proteins were linked to cardiovascular disease, type 2 diabetes and stroke," he added.

Dr Shrey Kumar Srivastav, senior consultant at Sharda Hospital, said that subtle symptoms of heart disease, such as fatigue, shortness of breath, swelling in the lower legs, dizziness, and jaw pain, are often overlooked or attributed to stress and ageing. "Women, in particular, may experience atypical signs like extreme fatigue, indigestion, or upper abdominal pain instead of classic chest pain, leading to delayed diagnosis," he added.

Can Mental Health Issues Trigger Heart Diseases?

Chronic stress can trigger harmful cardiovascular effects, including elevated blood pressure, increased heart rate, and inflammation—key contributors to heart disease. Anxiety and depression further impact heart health by disrupting sleep patterns, raising stress hormone levels, and encouraging unhealthy habits like poor diet and inactivity.

Mental health issues like depression and anxiety have a profound impact on the heart. They don’t just affect emotions but can increase inflammation and put extra strain on the cardiovascular system, warns Dr Srivastav.

Certain risk factors, such as obesity and diabetes, disproportionately affect women, making them more vulnerable to heart failure with preserved ejection fraction (HFpEF). However, due to gender-specific symptom variations, heart disease in women often goes undiagnosed for longer.

Obesity is more prevalent in women than men and is a major risk factor for heart failure. Diabetes, too, has a greater impact on women’s heart health, yet diagnosis and treatment delays are common. Addressing this gap requires increasing awareness, training healthcare providers, and promoting early diagnostic tools,” explains Dr Srivastav.

How Can You Protect Your Heart?

A simple yet effective way to support heart health is by committing to a brisk 30-minute walk daily. Walking not only helps regulate blood pressure and manage weight but also improves circulation and reduces stress.

"Regular physical activity, paired with a heart-healthy diet rich in fruits, vegetables, whole grains, and lean proteins, significantly lowers cardiovascular risks," advises Dr Srivastav.

Heart disease can often go undetected until a major event occurs, making routine screenings essential.

- For women: Begin screenings around age 30 and continue with regular checkups.

- For men: Start screenings at age 35.

Health screenings, including blood pressure checks, cholesterol tests, and electrocardiograms (ECGs), are critical for early detection of silent heart conditions.

The Democratic Republic of the Congo is actively expanding Ebola treatment capacity as the country battles its worst and fastest-growing Ebola outbreak. But a growing shortage of health workers is threatening the ability to run the new treatment centres and contain and manage transmission and infections.

According to the latest figures by Congolese authorities on September 23, the outbreak has across into seven provinces, with 7,773 confirmed cases and 3,759 deaths. The WHO says transmission remains out of control, even though cases are going down in some areas.

The situation is particularly grim in North Kivu, where cases increased by 73% over three weeks. At the same time, cases fell by 26% in Ituri and 15% in Haut-Uele between August 31 and September 20, highlighting how differently the outbreak is behaving across provinces.

More Treatment Centres May Not Be Enough

The country has rapidly increased its capacity to treat patients. By September 1, affected provinces had 59 facilities with 1,346 beds, compared with just one nine-bed treatment centre when the response began in May. More than 4,000 additional health workers had also been deployed.

But beds and buildings can only help if there are enough people to staff them. According to WHO officials, an Ebola treatment centre can require around 300 healthcare professionals, including doctors, nurses, anaesthetists and hygiene staff. Some newly established centres therefore do not have enough personnel to operate at full capacity.

This creates a difficult situation of treatment infrastructure being expanded, but the workforce needed to run it is not keeping pace.

Ebola Pressure On Health Workers

Ebola treatment is particularly laborious as healthcare workers must provide intensive care while following strict infection-prevention measures.

Patients may require monitoring for dehydration, bleeding and other complications, while staff must work in protective equipment and follow procedures designed to prevent transmission.

The response has also been impacted by insecurity, population displacement, movement between communities and a strike by some health workers over unpaid wages. These factors can make it harder to maintain staffing.

Early treatment is key as many patients are still reaching healthcare facilities late. WHO previously reported that around 60% of weekly Ebola deaths were occurring in communities rather than treatment centres, pointing to delays in detection and access to care.

Early Treatment Is Important

Ebola can cause fever, weakness, vomiting, diarrhoea and, in severe cases, bleeding and organ failure. The longer a severely ill patient remains without appropriate supportive care, the harder the disease can be to manage. Treatment centres help isolate infectious patients helps break transmission chains.

Children are another major concern in the current outbreak. Nearly one in four confirmed cases are children, but they account for almost one in three deaths. Children under five have been particularly vulnerable as more than 60% of confirmed cases in this age group resulting in death, compared to fewer than 30% among adults, according to WHO.

Developments In Vaccine & Treatment So Far

The outbreak has been identified as being caused by Bundibugyo virus, one of the viruses in the Ebola family. WHO reported a case fatality ratio of 48.3% among confirmed cases in the DRC as of September 7.

There is currently no approved vaccine or specific treatment for Bundibugyo ebolavirus, which means, health officials are completely relying on breaking transmission chain and providing prompt medical care to control the spread.

But the latest unfortunate developments point to a problem that could make containment even more challenging. The response desperately needs enough trained people, supplies and access to affected communities.

As there is currently no vaccine for Bundibugyo virus, health authorities have approved 70,000 doses of Ervebo, vaccine meant for a much familiar Zaire strain of Ebola. Health workers in DRC have begun receiving the Ervebo doses as part of an experimental trial to test if it would work on current Ebola outbreak.

With speed, sudden drops and dizzying twists at hundreds of feet in the air, roller coasters are meant to give riders an adrenaline rush and thrill. But a recent incident related to brain bleeding has shed light on the harmful impact of these extreme movements inside the brain.

A recent investigation found discovered that serious brain injuries have been allegedly linked to the X2 roller coaster at Six Flags Magic Mountain in California.

According to CNN, more than 100 people have allegedly suffered brain injuries after riding the attraction over the past two years. Three lawsuits were filed this week against Six Flags.

Two women who rode X2 just six days apart in July suffered severe brain haemorrhages and required emergency surgery. Doctors treating them attributed their injuries to rapid acceleration and deceleration experienced during the ride.

The cases raise the medical question of what happens to the brain when the body is subjected to sudden, powerful changes in speed and direction?

Can Roller Coasters Cause Brain Bleeds?

The brain is surrounded by cerebrospinal fluid, which cushions it against everyday movements and minor impacts. However, this protection has its own limits.

When a roller coaster suddenly accelerates, brakes or changes direction, the head and brain may not always necessarily move at exactly the same speed.

The brain can shift, stretch or rotate within the skull, placing strain on delicate blood vessels and nerve fibres. In extreme circumstances, these forces can tear blood vessels and cause bleeding inside the skull.

So it's not necessary that a person needs to hit their head against a hard surface to sustain a traumatic brain injury. Rapid rotational movements alone can sometimes cause significant damage to the brain.

What Is A Subdural Haematoma?

A subdural haematoma is a life threatening brain injury, in which the blood collects between the brain's outer protective covering, called the dura mater, and the brain's surface.

Sudden acceleration and deceleration can tear the veins that connect the brain to its surrounding structures.

As blood accumulates, pressure inside the skull increases. This can compress brain tissue and, in severe cases, require emergency surgery to remove the blood and relieve pressure.

G-Forces Are Another Factor

G-force means the acceleration experienced by the body relative to Earth's gravity. During sharp turns, steep drops and sudden brakes, roller coaster riders experience changing G-forces. However, G-force alone does not determine whether someone will sustain a brain injury.

The speed and direction of head movements, specially rapid rotation, may also contribute to brain bleeds. A small 2017 study found that roller coasters could produce brain movement and strain comparable to mild football headers. However, the researchers did not find evidence of an immediate risk of acute brain injury on the rides studied.

Warning Signs After Riding A Roller Coaster

Serious neurological injuries associated with roller coasters are considered to be rare. The Six Flags cases do not establish that an ordinary roller coaster rides will have the same risks as X2.

People with existing vascular abnormalities, previous head injuries or those taking blood-thinning medications may face additional risks.

A headache after a roller coaster ride may seem harmless, but certain symptoms require immediate medical attention.

According to the US Centers for Disease Control and Prevention, warning signs of a traumatic brain injury include worsening headaches, repeated vomiting, confusion, slurred speech, seizures, weakness and loss of consciousness. Symptoms can appear immediately or develop hours later.

A popular organic applesauce has been recalled in the US after routine testing by the US Food and Drug Administration (FDA) revealed high levels of patulin, a toxin produced by certain molds that can grow on apples.

Wakefern Food Corp. voluntarily recalled select containers of Wholesome Pantry Organic Unsweetened Apple Sauce after the patulin levels were found to exceed food safety limits. No illnesses linked to the toxin have been reported yet.

The recall involves 23-ounce plastic jars with UPC 04119005677 and a best-by date of June 16, 2027. The product was sold through ShopRite, Price Rite Marketplace, The Fresh Grocer, Gourmet Garage and Fairway Market.

What Is Patulin?

Patulin is a mycotoxin, meaning it is a toxic chemical produced by certain species of fungi or mold.

The FDA identifies molds from genera including Penicillium, Aspergillus and Byssochylamys as sources of patulin. Apples are one of the best-known sources, particularly when fruit is bruised, damaged, rotten or improperly stored.

When contaminated apples are used to make products like apple juice or applesauce, the toxin can remain it. The pasteurisation does not eliminate patulin, so simply heating an apple product is not a reliable way to get rid of the toxin.

How Dangerous Is Patulin?

The health concern depends on the amount and duration of exposure to patulin. According to the FDA, consuming food or beverages containing high levels of patulin may cause nausea and vomiting, while evidence also indicates that the toxin can damage cells. The agency monitors patulin because prolonged exposure to elevated levels may pose a serious health hazard.

The FDA has established an action level of 50 parts per billion (ppb) for patulin in apple juice, apple juice concentrates and apple juice products.

This does not mean that eating a food once above the regulatory limit automatically causes poisoning. Food safety limits are designed to control exposure and reduce potential health risks, particularly when contamination could occur repeatedly.

Patulin In Applesauce

Molds formed due to patulin can grow on apples that have been bruised, damaged or allowed to rot. Contamination can also happen during storage.

The problem can be difficult to identify simply by looking at the finished food. FDA guidance notes that some contamination can originate from internal problems like core rot that may not be obvious from the outside of an apple. Removing damaged fruit before processing is therefore an important control measure.

So, anyone who has the recalled Wholesome Pantry Organic Unsweetened Apple Sauce at home should not consume it.

Consumers should check the jar for the 23-ounce size, UPC 04119005677 and best-by date June 16, 2027. The company says recalled products can be returned to the store for a refund or replacement.
