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.

Nearly 100 children were harmed by a Great Ormond Street hospital limb reconstruction surgeon, Yaser Jabbar. A London-based children's hospital's internal review published a study that concluded that 94 out of 789 children who were treated by the doctor between 2017 and 2022, came to harm. Of these, 91 were harmed during surgeries he performed. Jabbar specialized in limb-lengthening and complex bone reconstruction procedures for children, many of which are inherently high-risk.

While the hospital said some complications are expected in such procedures, the investigation found that Jabbar’s practice fell below acceptable standards in multiple areas and that this directly contributed to patient harm. Great Ormond Street Hospital said it was deeply sorry for the suffering caused to children and families.

The BBC has attempted to contact Jabbar. He is understood to be living abroad and no longer holds a license to practice medicine in the UK.

Great Ormond Street Hospital: What Did The Report Find?

According to the report, more than a quarter of Jabbar’s surgical patients experienced harm. Thirty-five children suffered severe harm, while another child experienced severe harm unrelated to surgery.

Independent reviewers highlighted a series of troubling patterns. These included premature removal of bone fixation devices, operations carried out without a clear clinical rationale, incorrect placement of pins, and bone cuts made at the wrong anatomical level. The investigation also criticized how complications were identified and managed, suggesting delays and missed warning signs.

While the report stated it could not definitively determine whether every case of harm was avoidable, it concluded that the standard of care was suboptimal in many instances and that this had undoubtedly worsened outcomes for patients.

Nearly 100 Children Harmed: Families Speak Of Lifelong Trauma And Consequences

Although the report did not name individual cases, several families have previously shared their experiences publicly.

One of them is Bunty, a young girl born with a rare bone condition that left her left leg bowed and shorter than the other. She underwent multiple surgeries performed by Jabbar. Eventually, her lower left leg had to be amputated. Her case was classified as moderate harm.

Her father, Dean Stalham, told BBC, that the findings were “too little, too late” and questioned why concerns were not identified earlier. “These problems should have been spotted long before so many children were hurt,” he said.

According to another parent, Lizzie Roberts, as reported in the BBC, her son Tate was left in constant pain after surgery carried out by Jabbar when he was 16. Tate had been injured in a road accident years earlier, and the surgery was meant to address knee problems. Roberts said an operation was also performed on his ankle without consent and without clinical need.

“He is now facing further surgery and has had to drop out of college,” she said. Tate’s case was also classified as moderate harm.

Both families have called for a police investigation. The Metropolitan Police confirmed to the BBC that it would review the findings of the report to decide whether further action is required.

Questions Are Raised Over Hospital Culture

The investigation was launched in 2024, after concerns were raised internally. It followed a review by the Royal College of Surgeons, commissioned by the hospital, which flagged serious issues around working culture. Staff described the environment as toxic and raised concerns about inappropriate and incorrect surgeries being carried out on children.

Although independent clinicians reviewed patient records, Great Ormond Street Hospital collated and published the final findings. NHS England’s London region is now conducting a separate review into how the hospital handled the case.

The trust said it had already implemented recommendations from the Royal College of Surgeons, including better training on complaints handling, increased whistle-blowing support, and mandatory discussions of the most complex cases with the National Royal Orthopedic Hospital.

However, questions remain. Surgeon Sarah McMahon, who worked in the same service as Jabbar, reportedly raised concerns with hospital management in autumn 2021. According to a statement in Parliament by Dame Meg Hillier, no action was taken at the time.

'Bleakest Day' For Hospital

Great Ormond Street Hospital chief executive Matthew Shaw described the publication of the report as the bleakest day in the hospital’s history. He apologized unreservedly to affected families and said the trust acted quickly once formal concerns were raised in June 2022.

Shaw also pointed to the challenges of monitoring highly specialized surgical fields with very few practitioners nationwide. Still, he said transparency was essential.

“By publishing these findings, we hope to begin rebuilding trust with families,” he said. “They rely on us at the most vulnerable moments of their children’s lives.”

Nipah virus outbreak in India, after two cases have been confirmed from the state of West Bengal, has now led to an increased protection, with airports across Asia operating on high alert. Screenings are conducted in Thailand, Nepal and Vietnam over the fear of the outbreak. This virus has a high fatality rate and can spread from animals to humans.

Nipah Virus Outbreak In India: How To Stay Safe?

The World Health Organization (WHO) notes key steps to stay safe from Nipah virus.

Reduce Risk Of Bat to Human Transmission

WHO recommends that keeping bats away, especially from date palm sap and other fresh food products could reduce the risk of infection. WHO notes that freshly collected date palm juice should be boiled, and fruits should be thoroughly washed and peeled before consumption. Fruits with any sign of bat bites should be discarded.

Reduce Risk Of Animal to Human Transmission

WHO notes that people must wear protective clothing like gloves and more while handling sick animals like pigs and horses, and during slaughtering and culling procedures. WHO also notes that in areas where the virus is present, when establishing new pig farms, considerations should be given to the presence of fruit bats in the area and in general, pig feed and pig sheds should be protected against bats when feasible.

Control Nipah Virus in Pigs

In past outbreaks of Nipah involving pig farms, several measures were implemented to reduce transmission including: routine and thorough cleaning and disinfection of farms; quarantining animal premises in the case of suspected cases; culling of infected animals, with close supervision of burial or incineration of carcasses; and restricting or banning the movement of animals from infected farms to other areas.

Reduce Risk Of Human-to-human Transmission

People who have Nipah virus like symptoms must be referred to a health facility. Early supportive care is the key to better health. The WHO guidelines also note that closed and unprotected contact with sick people must be avoided, along with practicing basic hygiene rules like washing hands must be practiced.

Nipah Virus Outbreak In India: Can This Infection Become The Next Pandemic?

Many are worried about the Nipah virus outbreak and are speculating whether this could spread to an extent that it could become the next pandemic. Dr T.S. Anish, professor of community medicine and nodal officer for Nipah at the Kerala One Health Centre for Nipah Research and Resilience, as reported by South China Morning Post, said health authorities closely monitor all suspected Nipah cases to make sure no infections are missed. However, he explained that most people who are tested eventually turn out to be negative.

“Out of 100 suspected cases, almost all are usually negative,” he said. He added that tracing every contact of a Nipah patient is difficult, so there is always a chance that a case may appear outside the known contact list. Still, he believes the current outbreak is likely to remain small, affecting fewer than 10 people.

Avian or bird flu (H5N1) is a viral infection that spreads in birds, cows and other animals and can cause severe illness and at times, be fatal to humans in rare cases. Until now, the flu primarily affected wild aquatic birds including ducks, geese, gulls and poultry such as chickens as well as turkeys.

However earlier this month, a dairy cow in the Netherlands appears to have been contracted bird flu, making this the first time cattle outside of the United States has suffered the infection.

Previously, transmission of avian flu from cattle to humans has only been reported in the US among farm workers exposed to infected cattle or contaminated environments, and such cases remain sporadic and all developed only mild symptoms.

How Was The Cow Infected?

According to a detailed letter from the Dutch agriculture minister, a cat on a dairy farm in the province of Friesland died from H5N1 last month, which prompted officials to sample blood and milk from cattle at the farm.

Out of the 20 tested, one cow had antibodies to the virus in its milk but did not test positive for the virus itself. “There are also no signs of avian influenza spreading to other dairy farms,” the minister wrote.

The cow had mastitis and respiratory problems last month and its milk was not processed, the letter stated. Also, milk from the farm had been pasteurized, which inactivates the virus and prevents it being transmitted to humans.

“This means that there is very little chance that virus from the infected cow has ended up in the milk for human consumption,” the minister assured. It remains unclear how the virus arrived at the farm or how the cat and cow became infected.

Since October 2025, more than three dozen farms in the Netherlands have had outbreaks and over 1.5 million chickens, turkeys and ducks have been killed to stop the virus’ spread.

Is Bird Flu Dangerous For Humans?

The H5N1 strain drew worldwide concern in the early 2000s because of its high fatality rate in infected people. Although sustained human-to-human transmission is uncommon, infection can occur through close contact with sick or dead birds, their droppings, or contaminated environments.

Bird flu has posed major challenges for both the poultry industry and public health systems, with outbreaks often resulting in large-scale culling to limit the spread.

India has experienced recurring avian influenza outbreaks, particularly in regions with dense poultry farming. Even with strict control measures in birds, the risk of human infection persists, making awareness, hygiene practices, and preventive steps essential for protecting public health.

The common ways humans can contract the virus include:

• Direct contact with infected birds: Handling sick or dead birds, cleaning poultry farms, or working in live bird markets increases the risk
• Exposure to contaminated surfaces: The virus can survive on surfaces such as bird cages, equipment, and clothing. Touching these and then touching the eyes, nose, or mouth can lead to infection
• Consumption of undercooked poultry or eggs: While properly cooked poultry is safe, raw or undercooked meat and eggs from infected birds may pose a risk
• Airborne transmission in poultry farms: In rare cases, workers in enclosed spaces with infected birds may inhale tiny virus-laden particles
