A newly developed deep learning-based artificial intelligence (AI) system can read heart MRI scans as accurately as medical specialists.

The deep learning model developed by researchers at the University of Pennsylvania is trained on more than 300,000 MRI video clips from roughly 20,000 patients.

The system matches specialists in assessing heart function and diagnosing many heart conditions, according to a study published in the journal Nature Biomedical Engineering.

“Cardiac MRI is one of the most powerful tools available to cardiologists, but interpreting these scans requires rare expertise, and many hospitals -especially community and rural centers- lack specialists who regularly read complex cardiac MRI studies,” said Rohan Shad, an integrated cardiothoracic surgery resident in the Perelman School of Medicine at the University of Pennsylvania.

How The Deep Learning Model Worked

In the study, the researchers described a foundational vision system for cardiac MRI that is capable of representing the breadth of human cardiovascular disease and health.

The “foundation model” learns by linking MRI videos to their corresponding radiology reports, enabling it to recognize a wide range of conditions without extensive labeled data.

In tests, it estimated ejection fraction with expert‑level accuracy and identified severe heart dysfunction far more effectively than traditional AI methods.

It also diagnosed 39 cardiac conditions — including genetic problems like hypertrophic and dilated cardiomyopathies.

In a real‑world screen of more than 40,000 scans, the AI flagged 112 previously undiagnosed cases of hypertrophic cardiomyopathy.

According to researchers, the system could help hospitals without specialized cardiac imaging expertise detect rare but treatable diseases earlier.

What Is A Cardiac MRI

A cardiac MRI is a scan of the heart in which radio waves and magnets create images. It shows the parts of the heart, such as chambers, valves, and muscles, are working ― including how the blood moves.

A cardiac MRI is typically performed to

• decode heart symptoms like chest pain, shortness of breath, or fainting
• diagnose congenital heart disease, heart failure, heart masses, valve disease,
• understand muscle damage, infection, protein buildup, and iron deposits
• check damage post a heart attack

AI And Heart Health

AI-powered techniques such as Machine Learning and Deep Learning are transforming how heart diseases are detected, treated, and managed globally.

The technology has enabled faster analysis of large amounts of medical data—such as ECGs, heart MRIs, and patient records. It also flags patterns that may be missed by humans, and helps in early detection, treatment, and improving survival rates.

In 2024, the American Heart Association issued a scientific statement on the use of AI in improving outcomes in heart disease.

The objective aimed "to enable precision medicine and implementation science in cardiovascular research and clinical care".

However, it urged policymakers to develop principles and ethical guidance for the development and application of AI/ML-based digital health.

While fevers are often overlooked and brushed aside or even managed with antibiotics — a dangerous trend — an alarmingly nationwide study linked it to infectious diseases with far-reaching consequences.

The report, based on data of over one lakh individuals in India with fever, between 2023 and 2025, showed that these were not vague or self-limiting, but in more than 30 percent or one-third cases had clear links to serious infections, such as dengue, and typhoid.

According to the report by healthcare diagnostics company Thyrocare, the fevers were mostly linked with

• typhoid – in over 18 percent cases
• dengue -- over 14 percent cases.
• Other diseases include malaria, chikungunya, and leptospirosis.

Presence Of Multiple Infections

Importantly, the findings highlighted the presence of co-infections in 10 per cent cases. The most common was a combination of dengue and typhoid.

Dr Preet Kaur, Chief Scientific Officer, Thyrocare, said that a significant number of patients carry serious infections, sometimes more than one at a time, revealing patterns that simple assumptions cannot capture.

"Beyond the visible rise in temperature, laboratory markers highlight hidden stress on organs, from drops in platelet counts to elevated liver enzymes, underscoring that fever is a systemic signal, not an isolated event," she added.

Further, the report noted that dengue positivity declined significantly over the three-year report period, malaria increased despite its lower overall base.

Typhoid and chikungunya rose in 2024 before easing in 2025 but remained present across the testing population.

Fever: Men Vs Women

The report noted that more women were affected with typhoid than men. On the contrary, men reported more malaria cases.

More than 32 percent of females had fevers compared to 29 percent of men. Fevers in women was largely driven by higher typhoid detection (21 percent vs 15 percent).

Malaria affected men more than twice as often as women (1.1 percent vs 0.5 percent).

The lab reports also revealed key physiological markers such as platelet counts and liver function among people with fever, dengue, and malaria.

Low platelet levels were seen in

• 27 percent of patients with fever
• 80 percent malaria positive patients
• 37 percent dengue-positive patients

• All fever patients (56 percent) showed elevated SGOT levels and 37 percent SGPT
• Liver stress was seen across patients with dengue, malaria and leptospirosis.

Dengue cases rose throughout the year and typically peaked around October.

Typhoid positivity steadily fell from 2023 to its lowest in 2025. Despite a mild monsoon spike each year, 2025 remained consistently lower overall.

Chikungunya cases rose gradually from lower, volatile levels in 2023, peaked sharply in 2024, and moderated to a softer trend in 2025.

Malaria positivity remained relatively low overall but increased during the monsoon months, with transmission peaking between May and September.

Over the three-year period, malaria positivity rose from 0.5 percent to 1.1 percent, indicating a gradual increase despite its lower overall base.

New Delhi: There is a particular kind of frustration that comes with lying in bed, physically spent after a long day, and finding that sleep simply will not arrive. The body is done. The mind is not. This experience has a name in sleep medicine, and it is becoming less of an anomaly and more of a pattern for a growing number of people.

In an interview with Health and Me, Dr Shivani Swami, Additional Director – Pulmonology, CK Birla Hospitals, Jaipur, decoded the role of cortisol in affecting sleep and rest patterns.

The explanation starts with cortisol

Stress, whether from work pressure, unresolved worry, or the accumulated friction of a demanding day, keeps cortisol levels elevated into the evening. Cortisol is the hormone that keeps the brain alert and ready to respond. It has an important job during the day. The problem arises when it does not fall away as the evening progresses, which is what stress prevents. The brain receives no signal that the threat has passed, so it stays primed. Sleep requires the opposite of primed.

Screen use in the hours before bed adds another layer. The blue light that phones, laptops, and televisions emit suppresses melatonin, which is the hormone the body uses to initiate sleep. This is not a subtle effect. It shifts the body’s internal clock, making the brain read the late evening as daytime. People who spend an hour on their phone before bed are, in physiological terms, making sleep harder to reach.

Irregular schedules create their own complications

The body’s circadian rhythm is calibrated by consistency. When sleep and wake times shift from one day to the next, the rhythm loses its anchor. The body cannot predict when rest is coming, so it stops preparing for it at a reliable time. This is why erratic schedules, even among people who eventually get enough total sleep hours, tend to produce poor-quality rest.

The mental dimension sits separately from all of this. A mind that is processing, planning, replaying, or anticipating does not transition easily into sleep, regardless of how exhausted the body is. The cognitive activity itself is stimulating enough to override physical fatigue. This is what produces the wired quality that makes the tiredness feel irrelevant.

Left unaddressed, the pattern compounds

Shortened or fragmented sleep affects concentration, mood, immune function, and judgement. People become harder to disturb at first and then more fragile over time as the deficit accumulates.

What interrupts the cycle is not dramatic. A consistent bedtime and wake time, maintained even when it feels inconvenient, gives the circadian rhythm something to organise around. Screens set aside an hour before bed allow melatonin to do its work. A brief wind-down practice, whether reading, stretching, or simply sitting quietly, gives the brain a transition rather than asking it to move directly from full engagement to sleep. Stress that is processed during the day through breathing, reflection, or physical activity is less likely to resurface at night looking for somewhere to go.

The ideal sleep set-up

A cool, dark, and quiet sleep environment reduces the stimulation the brain has to work against. None of these are large interventions. The difficulty is the consistency they require, which is harder to maintain than any single habit change.

When the pattern persists despite reasonable adjustments, it warrants clinical attention. Chronic sleep disruption rarely resolves without some form of structured support, and the longer it continues, the wider its effects spread.

Healthcare in India must move beyond curative treatments to include preventive and holistic health, said experts today.

Speaking at a public health event in New Delhi, organized by the Illness to Wellness Foundation, the experts stressed the need to integrate technology, tradition, and lifestyle interventions to build a healthier, more resilient population in the country.

“Healthcare is not limited to curative treatments. It includes preventive, promotive, palliative, and rehabilitative care, much of which happens within the community,” said Rajesh Bhushan, Former Secretary, Ministry of Health & Family Welfare.

He called for building a culture of health-seeking behavior through community-focused programs and technology integration.

“Technologies like artificial intelligence (AI) and machine learning (ML) can improve the efficiency and quality of healthcare delivery, when combined with systems of digital public health infrastructure, including the Ayushman Bharat Digital Mission (ABDM) and the Ayushman Bharat Health Account (ABHA), which enable interoperability, longitudinal health records, and a more integrated healthcare ecosystem,” Bhushan added.

India today stands at a critical juncture in its healthcare journey. Rapid urbanization, changing lifestyles, rising stress levels, and increasing screen time are contributing to a growing burden of chronic conditions.

The experts argued that the real challenge will be to prevent disease and enable people to live healthier, longer, and more balanced lives.

Anil Rajput, Chairperson, Advisory Council, Illness to Wellness Foundation, urged for a more personalized and holistic understanding of health to build effective preventive systems.

Building Awareness On Healthcare

Dr. T S Kler, Chairman & HOD – BLK-Max Heart & Vascular Institute and Chairman Pan Max – Electrophysiology, spoke about the importance of leveraging public healthcare systems not only for treatment, but also for building awareness around health and prevention.

Amid rising cases of premature deaths linked to lifestyle risks and environmental factors, the experts advised keeping health as the foremost priority, far above all else.

"We must move towards an integrated, holistic model that combines allopathy with traditional systems of medicine, ensuring a more balanced and patient-centric approach. Equally important is the need to create greater awareness through continuous dialogue and education, as a lot can be achieved with the resources we already have,” said Dr. Kler, a Padma Bhushan awardee.

“The real shift we need is from managing disease to building a culture of health ownership. As stakeholders across sectors, our role is not just to develop systems, but to create awareness and belief that preventive and person-centric healthcare is achievable,” added Dr. Ravi Gaur, Co-Chair, FICCI Digital Health Task Force.

The event also featured a series of thematic discussions examining multiple dimensions of holistic health and well-being.

These include conversations around mental health as a critical component of productivity and daily life, with a focus on managing stress, addressing burnout, supporting students, and fostering more open and supportive environments across workplaces and educational institutions.
