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 US Food and Drug Administration's independent advisory panel has recommended approval of Moderna's mRNA-based influenza vaccine for older adults.

The panel backed the vaccine, known as mFLUSIVA, for adults aged 50 years and older, concluding that its benefits outweigh its risks.

If ultimately approved by the FDA, mFLUSIVA would become the world's first messenger RNA (mRNA) vaccine for seasonal influenza. The development could provide a new tool against a disease that causes an estimated 15 million to 60 million illnesses, 180,000 to 700,000 hospitalizations, and 17,000 to 75,000 deaths annually in the United States, according to data from the US Centers for Disease Control and Prevention (CDC).

What Did The FDA Advisory Panel Decide?

The recommendation came from the Vaccines and Related Biological Products Advisory Committee (VRBPAC), which reviews vaccine applications and advises the FDA.

The meeting marked the committee's first review of a new vaccine application since 2023 and could lead to the first vaccine approval under the second Trump administration.

In a unanimous vote, all nine panel members supported the use of Moderna's mFLUSIVA vaccine for adults aged 50 to 64 years, as well as for those aged 65 years and older—the age group that had previously raised regulatory concerns.

However, before the vaccine can be made available for the upcoming flu season, it must receive formal FDA approval and be recommended by the CDC's Advisory Committee on Immunization Practices (ACIP). The CDC advisory panel has not recently convened due to ongoing legal and administrative challenges. An FDA decision on the vaccine is expected by August 5.

How Effective Is Moderna's mRNA Flu Vaccine?

According to Moderna, the vaccine outperformed standard-dose flu vaccines in adults aged 50 to 64 years.

In a large clinical trial involving approximately 40,000 adults aged 50 years and older, Moderna's mRNA vaccine reduced influenza cases by about 27% compared with another routinely used flu vaccine.

The company also conducted a smaller study among adults aged 65 years and older. The results showed that mFLUSIVA generated a strong immune response compared with a high-dose influenza vaccine already recommended for seniors.

FDA adviser Dr. Anna Durbin of Johns Hopkins University described the immune-response data as "very compelling," adding that "the vaccine looks very promising," AP News reported.

Like Moderna's COVID-19 vaccines, mFLUSIVA uses messenger RNA technology. Rather than introducing a weakened or inactivated virus, mRNA vaccines deliver genetic instructions that help the body's cells produce proteins that trigger an immune response. This approach allows vaccines to be updated more quickly and may improve protection against evolving viruses.

Is The Vaccine Safe?

Moderna's data showed no major safety concerns.

The most commonly reported side effects included:

• Injection-site pain
• Fever
• Headache
• Fatigue
• Muscle aches

These reactions were generally temporary and are commonly seen with many vaccines. However, they occurred somewhat more frequently than with currently available flu vaccines. FDA reviewers noted that this is typical of mRNA-based vaccines.

What's Next?

If approved, Moderna plans to conduct a large post-approval study involving approximately 400,000 adults aged 65 years and older.

Half of the participants will receive the mRNA vaccine, while the other half will receive one of the currently recommended flu vaccines for seniors. The study is expected to continue across two influenza seasons.

A Moderna executive said the company hopes to make the vaccine available to patients in time for the upcoming flu season, Reuters reported.

Indian President Droupadi Murmu, on the occasion of World Sickle Cell Day 2026, today expressed confidence that the country can eradicate sickle cell disease well before the 2047 target.

Addressing the International Sickle Cell Day commemoration at Omkareshwar, Madhya Pradesh, President Murmu noted that the National Sickle Cell Anaemia Elimination Mission, launched in 2023, has so far "screened seven crore people, ranging from newborns to those up to 40 years of age."

Calling it "one of the largest initiatives for genetic disease screening in the world," she added that the mission has detected sickle cell disease "in approximately 2.5 lakh people so far, and over 20 lakh carriers of the disease have also been identified."

"Through the collective strength and active engagement of all states, we will succeed in achieving our national goal of eradicating sickle cell-related diseases from the country well before the year 2047," the President said.

The President highlighted three key dimensions of the mission:

• Spreading large-scale awareness and providing pre-marital genetic counselling;
• Identifying the disease in a timely manner through comprehensive screening; and
• Ensuring continuity of care while guaranteeing a holistic approach to management.

She also stressed the need for collective efforts to raise awareness and eliminate the genetic blood disorder, particularly among tribal communities.

What Is Sickle Cell Disease?

Sickle cell disease is an inherited blood disorder that affects the shape and function of red blood cells. Instead of being round and flexible, the red blood cells become sickle- or crescent-shaped, making it difficult for them to move smoothly through blood vessels.

The chronic single-gene disorder causes a debilitating systemic syndrome characterized by chronic anemia, acute painful episodes, organ infarction, chronic organ damage, and a significant reduction in life expectancy.

"Sickle cell disease (SCD) is one of India’s most pressing inherited blood disorders, with an estimated 1 in 86 births among tribal and disadvantaged groups affected," Dr Manisha Madkaikar is Director - ICMR-National Institute for Research on Blood and Immune Disorders – Mumbai, told HealthandMe.

Children living with the condition often experience repeated hospital visits, missed school days and limitations in daily activities. Parents frequently face emotional distress, financial strain and the challenge of managing a lifelong medical condition.

What Is the National Sickle Cell Anaemia Elimination Program?

The National Sickle Cell Anaemia Elimination Program, introduced in the Union Budget 2023, focuses on addressing the significant health challenges posed by sickle cell disease, particularly among tribal populations in the country.

Implemented across 17 high-focus states, the programme aims to improve care and outcomes for sickle cell disease patients while reducing the prevalence of the disorder. The states are Gujarat, Maharashtra, Rajasthan, Madhya Pradesh, Jharkhand, Chhattisgarh, West Bengal, Odisha, Tamil Nadu, Telangana, Andhra Pradesh, Karnataka, Assam, Uttar Pradesh, Kerala, Bihar, and Uttarakhand.

Implemented in mission mode under the National Health Mission (NHM), the program aims to eliminate sickle cell genetic transmission by 2047.

Over a three-year period from 2023-24 to 2025-26, the program targets screening approximately seven crore people, promoting early diagnosis and intervention on a large scale.

Did COVID-19 emerge naturally or from a laboratory leak? Nearly seven years after the pandemic began in late 2019, and despite more than 7.1 million confirmed deaths worldwide and numerous investigations, there is still no definitive answer about the virus's origins.

Now, Tulsi Gabbard, on her last day as the Director of National Intelligence, US, has reignited the debate by alleging that Anthony Fauci, who led the scientific and medical response to the COVID-19 pandemic in America, funded research at China's infamous Wuhan Institute of Virology that contributed to the pandemic.

"The COVID-19 pandemic caused tremendous hardship and pain for millions of Americans and countless people around the world," Gabbard said in a statement.

"After years of lies, censorship, and cover-ups, the American people deserve transparency, truth, and accountability."

What Are the Documents?

According to Gabbard's office, the materials were released following a year-long declassification review conducted by the Office of the Director of National Intelligence (ODNI) as part of President Trump's transparency initiative.

During the review, officials reportedly gathered testimony from intelligence community whistleblowers who alleged they faced retaliation for challenging official assessments of the virus's origins.

Gabbard said the testimony revealed a pattern of suppressing dissenting views, discouraging debate, and sidelining evidence that conflicted with prevailing intelligence assessments.

What Does The Documents Show?

According to Gabbard, the newly declassified communications and documents reveal that

• Fauci worked with intelligence officials to suppress information related to the COVID-19 lab-leak theory and allegedly had a role in directing US funding for coronavirus research.
• Fauci influenced Intelligence Community assessments regarding the origins of COVID-19.
• Fauci misled Congress during his 2024 testimony when he denied knowledge of or participation in discussions with intelligence officials about viral research.
• Fauci held significant influence during the pandemic and occupied multiple roles that shielded him from scrutiny.
• Fauci funded coronavirus research linked to efforts to develop so-called "universal vaccines."
• Fauci selected scientific advisers who encouraged intelligence agencies to support a natural-origin theory while downplaying the lab-leak hypothesis.
• Fauci publicly promoted narratives that discouraged debate over alternative explanations for the origins of COVID-19.
• Fauci maintained close relationships with intelligence officials, enabling him to influence both intelligence assessments and public narratives surrounding the pandemic.
• Fauci's statement — "not to my knowledge about COVID" — was inconsistent with documented communications regarding interactions with intelligence agencies.

Whistleblower Allegations

Importantly, the declassified materials also include testimony from whistleblowers who claim analysts supporting the lab-leak theory faced professional consequences. These include:

• A contractor was reportedly dismissed shortly after submitting a whistleblower complaint to ODNI.
• Analysts advocating for the lab-leak hypothesis were allegedly warned that career advancement decisions rested with leadership.
• Some whistleblowers claimed senior officials created barriers to anonymous reporting, fostering an atmosphere of intimidation.

What Happens Next?

Gabbard said these allegations have been referred to the intelligence community's inspector general for further review.

Whether the allegations lead to congressional hearings, legal action, or additional independent review remains uncertain.

Any conclusions will depend on careful examination of the documents, corroborating evidence, and responses from those named in the allegations. Fauci is yet to comment on the allegations.
