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.

Women, young ones and ones holding their babies, along with some men lined up on the outskirts of Zimbabwe's capital Harare for the injections of a new HIV prevention drug. The country launched it on Thursday. This drug needs to be administered only twice a year.

Why Is This Vaccine So Important For Zimbabwe?

Zimbabwe is a country where HIV led to tens of thousands of deaths in the last two decades. It is the first country to roll out lenacapavir, which is a long-acting drug that authorities have put their hopes on to slow down the HIV infection.

What Is So Special About The HIV Injections?

Clinical studies have demonstrated near-total protection for the drug and has been described as a 'turning point' for high risk groups by many experts. However, many have warned that its broad impact would require overcoming funding constraints, infrastructure gaps and the challenge of keeping patients engaged.

Immunologist at Emory University Rama Rao Amara, calls it a "wonder drug". The drug, known as lenacapavir has been approved by the Food and Drug Administration (FDA) and is made by Gilead Sciences.

How Does This Drug Differ From Earlier HIV Prevention Drugs?

In 2021, FDA approved injectable form of PrEP medication called cabotegravir, however, this required patients to take it in every two months. This was also an intramuscular dose that healthcare providers were to administer into the buttocks.

What changes with lenacapavir is its easy administration. Each dose lasts longer compared to other medications and requires to be administered twice a year.

The limitation with lenacapavir is its price tag of more than $28,000 per person per year. Carmen Pérez Casas, a senior strategy leader at Unitaid, a global health initiative based in Geneva, Switzerland said, "This is unaffordable. We need to get somewhere close to what previous options cost."

However, there is hope as the researchers published an analysis in The Lancet HIV that suggested generic versions of this drug could cost a person $25 per year.

Could This Drug Reshape HIV Prevention?

At the Zimbabwe launch, Constance Mukoloka, a sex worker, was among the first beneficiaries of this roll out which has happened by donor-support across 10 African countries, as reported by PBS News.

"I am safe, I can work with confidence now," said the 27-year-old sex worker. "When I took tablets, customers would see a container of pills and leave. They would never return due to fear," she said. "They couldn't tell the difference between PrEP and treatment drugs. With the work we do, that stigma costs you money."

Daily oral PrEP has been offered in Zimbabwe for years, along with condoms, vaginal rings and shorter-acting injections. However, sticking to the regimen has been difficult, especially for people dealing with stigma or irregular daily routines.

"I work in beer halls looking for clients. Sometimes I would get drunk and forget to take my drugs," Mukoloka said. "Sometimes I would work all night and not have time. Some clients refuse protection. They say ... 'Why should I use protection when I have paid?'"

Mexico has reported more than 2,700 new cases of measles so far this year, as per the government data. Most of these infections have been detected among infants and young children. Not too far away, in the US, as per the Centers for Disease Control and Prevention (CDC) data, 900 new cases have been confirmed.

However, unlike in the 1990s, the Secretary of Public Education in Baja California Sur, Alicia Meza Osuna, clarified that it is not a requirement to present the complete vaccination schedule for children to attend schools. However, in the Mexican city of Cabo San Lucas, specific health measures are being taken.

What Parents In Cabo San Lucas Must Keep In Mind?

• The standard school enrollment process will continue as usual, and families are not required to present a complete vaccination record to register.
• In areas where recent cases have been reported, localized health precautions may be introduced. Families in Cabo San Lucas should be prepared for temporary preventive measures if an outbreak occurs.
• Parents are advised to take their children to a medical facility if they notice symptoms such as fever, cough, runny nose, conjunctivitis, small white spots inside the cheeks, or skin rashes so they can receive timely medical care.
• Except during declared emergencies, vaccination certificates are not required for school admission.

What Happened In Mexico In The 1990s?

In the 1990s, the Ministry of Health (SSA) and the Ministry of Public Education (SEP) required that children be protected against diseases such as measles, polio, rubella, tetanus, diphtheria and tuberculosis before entering preschool or primary school, as part of the health prevention policies. However, at present, as Alicia Meza Osuna stated, "It is not a requirement to enroll children in school to present their vaccination card. Under no circumstances is it a requirement to present a complete vaccination schedule for a child to attend school."

What Is Measles?

Measles, also known as rubeola, is an extremely contagious viral illness that typically causes high fever, cough, runny nose, red and watery eyes, and a characteristic rash that begins on the face and spreads downward across the body. It spreads through respiratory droplets and can lead to severe and sometimes fatal complications, including pneumonia and inflammation of the brain known as encephalitis.

Although it is preventable through the safe and effective MMR vaccine, measles remains a serious threat in many regions. There is no specific cure, and treatment focuses on managing symptoms, according to the Cleveland Clinic.

What Are The Symptoms Parents Must Look Out For?

Measles has a high transmissibility, and high measles immunity levels are required to prevent sustained measles virus transmission.

This is why herd immunity for measles could be easily breached.

It easily spreads from one infected person to another through breathes, coughs or sneezes and could cause severe disease, complications, and even death.

Symptoms include:

• High fever
• Cough
• Runny Nose
• Rash all over the body

The most unique symptom or the early sign of measles in the Koplik spots. These are tiny white dots that look like grains of salt on red gums inside the cheeks that appear before the red rash starts to appear on a person's face and then the body.

Furthermore, the symptoms of measles are also characterized by the three Cs:

• Cough
• Coryza or runny nose
• Conjunctivitis or red and water eyes

How Long Does The Infection Last?

The progression of the symptom comes in two stages, first is the prodromal stage or Days 1 to 4, where one would notice high fever, cough, runny nose, red and watery eyes, sore throat, fatigue, and Koplik spots.

The second stage is called the rash stage or the days 5 to 10 or even more where rash start to appear on the hairline, and then it runs down the body. It lasts for several days and fades in the same order.

The first symptoms, notes the Centers for Disease Control and Prevention (CDC), appear 7 to 14 days after a measles infection. Often, it could also lead to ear infection, or even diarrhea. Though these complications happen in every 1 in 10 children or individual with measles.

Union Health Minister JP Nadda launched indigenously manufactured tetanus and adult diphtheria (Td) vaccine at the Central Research Institute in Himachal Pradesh's Kasauli on Saturday. The formal launch of the Td vaccine will now include the vaccine under the Universal Immunisation Programme (UIP). The Central Research Institute will supply 55 lakh doses to the UIP by April. The production is also expected to scale up progressively in subsequent years to further strengthen the Central Government's Universal Immunisation Programme, said Nadda.

Nadda also congratulated the scientists, technical experts and staff of the Central Research Institute Kasauli at the gathering, and described the launch Tb vaccine as a momentous and historic occasion. He also stated that the launch marked a significant step towards safeguarding national health security and strengthening India's public health infrastructure.

The minister also noted that the government under the leadership of Prime Minister Narendra Modi, set clear targets for achieving self-reliance in the health and pharmaceutical sectors. Nadda also said that the launch of the indigenously manufactured Td vaccine represents a concrete step towards the vision of Atmanirbhar Bharat in health and medicine.

India Is Pharmacy Of The World

He also highlighted the nation's global standing. He said that the minister also stated that India is widely recognized as the "pharmacy of the world" and is among the leading vaccine manufacturers globally.

He also said that India has achieved Maturity Level 3 in the World Health Organization's (WHO) global benchmarking of regulatory systems, reflecting the robustness of its vaccine regulatory framework. Institution like CRI, said Nadda, have also played a major role in achieving these standards.

From Decades Of Research To Digital Vaccination Tracking

The Union Health Minister said that historically, vaccines and medicines took decades to develop. The tetanus vaccine required years of global research, tuberculosis drugs evolved over nearly 30 years, and the Japanese Encephalitis vaccine took close to a century of scientific effort.

In contrast, during the COVID 19 pandemic, India developed two indigenous vaccines within nine months and administered more than 220 crore doses, including boosters. He added that vaccination certificates were issued digitally, reflecting the country’s expanding use of technology in public health delivery.

Highlighting international cooperation, he noted that under the Vaccine Maitri initiative India supplied vaccines to nearly 100 countries, with 48 receiving them free of cost. Public sector institutions such as the Central Research Institute also strengthened the country’s ability to meet both domestic and global demand.

The minister further said the Central Research Institute became the first government facility to manufacture vaccines under Good Manufacturing Practices standards, marking a major step in modernizing public sector vaccine production.

He described the Universal Immunisation Programme as the world’s largest vaccination drive. It currently provides 11 vaccines protecting against 12 preventable diseases, with significant contributions from the institute.

Every year about 2 to 2.5 crore children are born and a similar number of women become pregnant. From pregnancy registration onward, beneficiaries are tracked through digital platforms such as U WIN. Expectant mothers receive five antenatal check ups including at least one by a specialist, and monitoring continues until the child turns 16 years old, covering 27 doses.

The annual immunization cohort includes nearly 5 crore beneficiaries, around 2.5 crore pregnant women and 2.5 crore children. Due to systematic tracking and sustained immunization efforts, vaccine coverage in the country has reached nearly 99 per cent.
