An worrying animal study revealed that SARS-CoV-2 infection in fathers prior to conception can produce alterations in sperm, affecting children’s brain development and behavior and raising the likelihood of anxiety later on. This is in contrast to the well-established long-term consequences of Covid-19 infection on the brain.

According to research that was published in the journal Nature Communications, COVID-19 may have a lasting impact on generations to come. Male mice exposed to particular environmental and lifestyle factors—such as a poor diet prior to mating—may alter the behavior and brain development of their progeny.

Lead researcher Professor Anthony Hannan of the University of Melbourne’s Florey Institute of Neuroscience and Mental Health in Australia explained, “This is because the father’s experiences can alter the information carried in sperm, including specific RNA molecules, which transmit instructions for offspring development.”

The goal of the current study was to see whether the Covid virus would affect sperm RNA and the progeny in a similar way.

Before mating with healthy female mice, the scientists allowed male mice to recuperate from SARS-CoV-2 infection for a few weeks.

Compared to children of fathers who were not sick, the children had more worried behaviors.

All children whose fathers have COVID-19 showed more signs of anxiousness. The hippocampal region of the female offspring’s brain, which is crucial for anxiety, depression, and other emotional behaviors, also showed notable alterations in certain gene activity.

“These kinds of changes in the hippocampus, as well as other brain regions, may contribute to the increased anxiety we observed in offspring, via epigenetic inheritance and altered brain development,” said Carolina Gubert, a researcher at the Institute.

Subsequent examination of the sperm RNA from the infected fathers revealed that Covid had changed a number of molecules, including some that regulate genes thought to be crucial for brain development.

“If our findings translate to humans, this could impact millions of children worldwide, and their families, with major implications for public health,” Hannan said, urging further study.

A recent research by the Competition Commission of India (CCI) found that the use of AI technology is expanding quickly in India across a range of user industries, changing company operations, regulatory responses, and competition dynamics.

Although the introduction of AI has brought about significant improvements in productivity, creativity, and customer satisfaction, the study pointed out that new problems are starting to arise that could affect competition either directly or indirectly and prevent AI from reaching its full potential.

It looked closely at each of these elements and reviewed how legal and regulatory frameworks in India and other countries have changed to keep up with the quick development of artificial intelligence.

In order to comprehend AI markets and ecosystems, identify new and possible competition issues, and examine current and developing regulatory frameworks governing AI systems, the Management Development Institute Society (MDIS) conducted a report titled “Market Study on Artificial Intelligence and Competition.”

To provide a comprehensive and in-depth understanding of the various objectives, the study used both primary and secondary research methods, such as database analysis, semi-structured and structured interviews, stakeholder surveys, and literature reviews.

“The study has contributed to the collection of valuable information and insights regarding the structure of the AI ecosystem, market trends, AI application in user industries, possible competition issues in the AI industry and user industries, and other pertinent aspects,” the CCI stated.

The paper suggests several actions to safeguard consumer welfare, stop AI-driven anti-competitive behavior, and encourage the growth of a competitive AI ecosystem in India.

In order to achieve this, CCI will engage with international competition authorities and multilateral competition platforms, organize a conference on “AI and regulatory issues” in collaboration with pertinent stakeholders, hold targeted advocacy workshops on “AI and Competition Compliance,” concentrate on enhancing its technical capabilities and infrastructure, establish a think tank to share knowledge on issues pertaining to digital markets with a particular focus on AI, and take action to encourage inter-regulatory coordination.

Businesses are encouraged to implement transparency measures to lessen information asymmetry and to incorporate self-audit of AI systems for competition compliance in order to guarantee responsible autonomy while shielding markets from distortions. This will enable businesses to proactively identify and address possible competition concerns.

The World Heart Federation (WHF) and the World Health Organization (WHO) decided on September 29 as the date for World Heart Day celebrations when the event was first held in 1999 and formally commemorated in 2000.

In order to battle the world’s top cause of death, the day was created to increase awareness of cardiovascular diseases and encourage heart-healthy lifestyles. In order to establish a recurring yearly campaign, the date was moved from the last Sunday of September to September 29 starting in 2011.

With the theme “Don’t Miss a Beat,” the World Heart Federation and World Health Organization commemorate the 25th World Heart Day today, highlighting the fact that 80% of heart disease and stroke cases can be avoided by adopting healthier lifestyle choices including exercising, eating a balanced diet, and giving up smoking.

While the Philippines reports 143,486 CVD deaths in 2023, authorities in India, including Union Home Minister Amit Shah and Karnataka Deputy Chief Minister DK Shivakumar, encourage routine checkups in the face of a 30% increase in heart attacks among those under 40.

The goal of global programs is to increase access to cardiac care for 500 million additional individuals by 2030 through screenings, workshops, and awareness campaigns.

Early deaths from CVD are causing loved ones all across the world to miss out on time they should still spend together. For this reason, on September 29, we shall proclaim to the world: Don’t Miss a Beat.

In the WHO South-East Asia Region, eight individuals pass away from cardiovascular diseases (CVDs) every minute. According to Dr. Catharina Boehme, Officer-in-Charge, WHO South-East Asia, cardiovascular diseases (CVDs) are a major cause of death in the region, with half of these deaths occurring before the age of 70.

Hypertension, diabetes, alcohol and tobacco use, poor diets heavy in fat and salt, and sedentary lifestyles are major risk factors for CVDs.

She also pointed out shortcomings that impede progress, including insufficient financial and regulatory measures, lax policy enforcement, and inadequate oversight of the prohibitions on unhealthy commodities’ marketing, packaging, and advertising.

Amit Shah, the Home Minister, said on X, “On #WorldHeartDay may we all pledge to keep our hearts healthy with regular exercise and a balanced diet to gift ourselves and our loved ones happier lives” .

“On #WorldHeartDay, let’s unite to promote a heart-healthy community by embracing mindful lifestyle choices that protect our hearts today and for years to come,” the Ministry of Health stated on X.

Deputy Chief Minister- Karnataka, DK Shivakumar said on X, “#WorldHeartDay reminds us to care for this most vital part of our lives and make health a priority for ourselves and our society. Small steps like regular exercise, balanced food, and stress-free living can go a long way in keeping our hearts healthy. Let us value every heartbeat and protect it with conscious choices.”

On World Heart Day, there is a chance to spark global dialogue and involvement by utilizing compelling narratives to increase awareness of heart health issues. Use a collection of Don’t Miss a Beat resources to personalize World Heart Day.

In the 17th Asia Cup, India is playing its first Twenty20 International since defeating England 4-1 at home in January.

Additionally, it provides India with a vital platform for preparation for the upcoming T20 World Cup, which will be hosted in India and Sri Lanka and in which they will compete as the reigning champions.In the UAE, the Asia Cup 2025 will take place from September 9 to September 28. Dubai and Abu Dhabi will host each of the 19 games.

The senior team of Virat Kohli and Rohit Sharma, who declared their T20I retirements following last year’s World Cup victory, will not be participating in the Men in Blue’s first big competition. Prior to the England tour, the prolific duo also ended their Test careers, limiting their international presence to the ODI format.

At the Dubai International Cricket Stadium, India will play their first Group A match against the United Arab Emirates on September 10 and then Pakistan on September 14. On September 19, a match versus Oman will be place at Abu Dhabi’s Sheikh Zayed Cricket Stadium.

The last time we saw Rohit and Kohli wearing the Indian shirt was during their March ICC Champions Trophy championship run.

Afghanistan will play Hong Kong China in Group B at the Zayed Cricket Stadium in Abu Dhabi in the continental opener.

The match officials’ crew for the competition will be led by seasoned referees Andy Pycroft and Richie Richardson. The Asian Cricket Council (ACC) stated on Monday that the Super Four match officials list and tournament final match officials list will be revealed later.

According to fresh data issued by the World Health Organization (WHO) , over 1 crore people worldwide suffer from a mental health illness, with women making up over 53% of those affected.

According to the WHO’s World Mental Health Today and Mental Health Atlas 2024 reports, mental health disorders like depression and anxiety have a significant negative impact on people’s lives and the economy. They also advocated for increased funding and action to expand services that support and enhance people’s mental health.

According to WHO Director-General Dr. Tedros Adhanom Ghebreyesus, “transforming mental health services is one of the most pressing public health challenges.”

“Investing in mental health is an investment that no nation can afford to overlook because it benefits individuals, communities, and economies. It is the duty of every government and leader to take swift action and guarantee that mental health care is regarded as a fundamental human right rather than a privilege, he continued.

According to the reports, the most prevalent mental health conditions in both men and women are anxiety and depressive disorders. But altogether, women are disproportionately affected.

In total, 581.5 million women and 513.9 million men suffer from a mental illness.

Pregnant women and women in the year following childbirth were shown to have a high prevalence of mental problems, which frequently had detrimental effects on both mothers and infants. Depression affects over 10% of pregnant women and women in the year following childbirth worldwide. This number is thought to be significantly greater in low- and medium-income countries (LMICs), according to the reports.

The survey also revealed that suicide is still a terrible consequence, with an anticipated 727,000 deaths in 2021 alone. It is a major cause of death for youth in all nations and socioeconomic backgrounds, and there hasn’t been enough success in lowering the suicide mortality rate.

Only 12% of the one-third reduction in suicide rates that is intended to be accomplished by 2030 will really be accomplished.

Furthermore, mental health illnesses have a tremendous economic cost because they cause lost productivity. According to the WHO report, anxiety and depression alone cost the world economy $1 trillion annually.

According to the 2024 Mental Health Atlas, just 45% of nations assessed their laws to be fully compliant with international human rights norms, and fewer nations have enacted or implemented rights-based mental health legislation.

The study also found that funding for mental health has stagnated, which is troubling. Since 2017, the median government spending on mental health has remained at just 2% of total health budgets, with low-income nations paying as little as $0.

The World Health Organization urged governments to step up their efforts immediately to improve mental health systems around the globe.

This entails maintaining investment in the mental health workforce, expanding community-based, person-centered treatment, reforming laws and policies to protect human rights, and equitably providing mental health services.

A wholesome snack valued for its health advantages, Makhana—also referred to as fox nuts or lotus seeds—has grown in popularity. Makhana, which is low in calories and abundant in dietary fiber, is frequently referred to as a superfood.

For ages, these crunchy white seeds—which are derived from the aquatic plant Euryale Fox—have been a traditional staple in many civilizations. Currently, their remarkable nutritional worth is acknowledged around.

Makhana, which is high in vital minerals and antioxidants, promotes heart health, facilitates digestion, and helps control weight. Because of its adaptability, it may be eaten roasted, in sweets, or just as a nutritious snack, making it a convenient and healthful option.

Additionally, makhana has a low glycemic index, which aids in the natural regulation of blood sugar levels, and is gluten-free, making it perfect for people with gluten intolerance.

Makhana is a nutrient-dense food that contains a variety of proteins, carbs, flavonoids, polyphenols, and vital minerals. Especially noteworthy:

• Packed with antioxidants: Flavonoids such as kaempferol and other polyphenols have strong anti-inflammatory and antioxidant effects.
• Low in calories: Makhana is a filling snack that is ideal for weight control because it doesn’t contain too many calories.
• Rich in dietary fiber: Fiber makes you feel fuller longer, assists with digestion, and speeds up your metabolism.
• Having a low glycemic index makes it a great meal option for controlling blood sugar levels.

The growing popularity of makhana as a heart-healthy and metabolism-friendly snack can be attributed to these qualities taken together.

Benefits of Makhana consumption for health

Aids in heart health
Heart disease-causing oxidative stress and inflammation are lessened by makhana’s antioxidants. Frequent consumption may increase HDL and decrease LDL, improving cardiovascular health and lowering the risk of hypertension and atherosclerosis.

Helps with weight control
Makhana’s high fiber content and low calorie content help suppress hunger and encourage fullness, which can lower daily caloric intake. When incorporated into a balanced diet, this satiating effect promotes an improvement in metabolic rate and can help with successful weight loss.

Helps control blood sugar levels
Makhana is a good snack choice for diabetics because of its low glycemic index, which raises blood sugar levels gradually. It can be eaten as roasted seeds in between meals or, in moderation, added to nutritious desserts with natural sweeteners like dates or jaggery.

Supports the health of the digestive system
Makhana’s high fiber content helps maintain a healthy digestive system by promoting regular bowel movements and warding off constipation. It can improve metabolism in general and intestinal health in particular.

Who should refrain from consuming makhana?
Even though makhana (fox nuts) provide many health advantages, some people should use caution when taking them. Certain medical issues may necessitate restricting intake in order to prevent negative effects, according to reliable sources.

People who are at risk for kidney stones
Oxalates, which are found in makhana, have the potential to cause kidney stones. Because oxalates may decrease the absorption of calcium and magnesium, people who have a history of kidney stones or are predisposed to them should limit their intake to prevent elevated risks.

People who are prone to allergies
Allergy reactions in those who are sensitive to nuts and seeds can range from minor rashes and itching to severe anaphylaxis. If you have any allergies, stay away from makhana or introduce it carefully.

People who suffer from intestinal ailments
High-fiber foods like makhana may be difficult for people with digestive disorders like inflammatory bowel disease (IBD) or irritable bowel syndrome (IBS) to digest, which could exacerbate symptoms like gas, bloating, or pain in the abdomen.

People who have excessive levels of uric acid or gout
Makhana has moderate amounts of purines, which are substances that can raise the body’s uric acid levels. It is advised that people who are prone to gout or hyperuricemia restrict their intake of purines, which includes consuming less makhana.

Individuals using blood thinners
Excessive consumption of makhana may interfere with blood-thinning drugs like warfarin because of its vitamin K concentration, which is involved in blood coagulation. Before taking such medications on a regular basis, people should speak with their healthcare practitioners.

Adding makhana to your diet: A guide

Makhana is adaptable and has several ways to be enjoyed:

Snack with a hint of salt and spices: A crispy, nutritious snack is made from lightly toasted makhana.

Desserts and puddings: Makhana can be made into a healthy dessert choice by adding natural sweeteners like dates or jaggery to it.

When used as a garnish, roasted makhana adds texture and nutrients to soups and salads.

When making stir-fries and curries: For an added crunch and nutritional boost, it can be used to a variety of recipes.

Researchers in the United States are developing a non-invasive method that uses ultrasound to precisely and less harmfully administer medications anyplace in the body.

A group of researchers from Stanford University is creating a novel method that encapsulates medications in nanoparticles and releases them at their designated locations using ultrasound.

The scientists demonstrated in rats that their method can administer painkillers to particular nerves in limbs and ketamine to particular brain regions in a study that was published in the journal Nature Nanotechnology. They discovered that nanoparticles are safer, more stable, and simpler to make using a novel sucrose formulation.

“It turns out that all you need to make this work is a little bit of sugar,” said Raag Airan, an assistant professor of radiology at Stanford Medicine.

The researchers discovered that the nanoparticles were responsive to ultrasound stimulation yet comparatively stable in the body when they contained a 5% sucrose solution.

This implies that the majority of the medication is only released where it is required, even if the nanoparticles are injected into the bloodstream and move throughout the body. When a narrow ultrasonic beam is administered externally, it locates the target and releases the medication.

Numerous medications could become safer and more effective with the implementation of such a system.

“We can minimize the off-target effects and maximize the therapeutic effect,” Airan stated.

At first, the nanoparticles were made up of a liquid core of rare chemical compounds encased in a polymer shell. The scientists attempted to modify the liquid core’s response to ultrasound by adding a range of common materials, such as salts and polymers, but it was unsuccessful.

They tried sugar at last. After experimenting with various sugar types and concentrations, the researchers discovered that adding 5% sucrose to the liquid core produced the optimum balance between stability at body temperature and ultrasonic sensitivity.

Rats that received an injection of free, unencapsulated ketamine and those that received ketamine encapsulated in nanoparticles with 5% sucrose were used to test the drug delivery system.

The nanoparticles showed tailored drug release when the researchers used ultrasound to target a specific area of the brain. This area received around three times as much medication as other areas of the brain.

According to the researchers, if the mechanism functions in humans, medical professionals could be able to prevent ketamine’s dissociative effects while separating the drug’s emotional effects, such as treating depression.

Living with diabetes means more than just checking your blood sugar — it’s about keeping it in a healthy range every day.

It also requires being mindful of when and what you eat, and knowing what needs to be done in case the blood sugar levels fall.

Over time, these constant challenges can lead to a feeling of diabetes distress.

With over 101 million people living with diabetes in India, diabetes distress or burnout typically affects 18% of those living with this condition.

For some, it manifests as irritability, frustration, or emotional fatigue. For others, it’s a quiet retreat—missing glucose checks, skipping medications, or avoiding appointments. Diabetes distress usually stems from the relentless demands of daily management. The emotional toll reflects that constant vigilance can take.

By acknowledging the mental and emotional effects of diabetes, individuals can begin to find a sense of balance, rebuild confidence, and reconnect with their support systems.

Technology can play an important role in easing the burden of diabetes and offer much-needed support in managing this distress.

Continuous glucose monitoring (CGM) devices provide real-time blood glucose alarms that let you know and take informed decisions the moment your glucose is too low or too high. It also allows you to see patterns and trends and helps you understand how food, activity, and insulin affect glucose levels.

 Dr Manjunath P R, Associate Professor, Consultant, Ramaiah Memorial Hospital, Bangalore, said, “Managing diabetes requires a holistic approach that nurtures both body and mind. Effective diabetes management is about striking a balance. A well-rounded routine includes nutritious eating, regular physical activity, and consistent glucose monitoring. Tools like Continuous Glucose Monitoring (CGM) devices play a vital role in this journey. By offering real-time insights into glucose trends, CGMs help individuals understand how specific foods, activities, or stressors affect their levels. This immediate feedback empowers people to make informed decisions, reduces uncertainty, and can significantly ease the emotional burden of diabetes.”

Diabetes distress often eases when the experience feels less isolating—and that’s where the power of family and community comes in. Through connected care, people with diabetes can share the responsibility of managing their health with family members.

It gives people the confidence to take charge of their health and have more meaningful conversations with healthcare providers.

Dr. Vivek Iyer, Head, Medical Affairs, South Asia, Abbott, said, “To ease the burden of diabetes distress and prevent burnout, Continuous Glucose Monitoring (CGM) devices can be transformative. Today’s CGMs go beyond tracking—they serve as comprehensive digital health platforms that foster connection. By allowing individuals to share real-time glucose data with loved ones and healthcare providers, CGMs help create a supportive, informed care network.”

Here are a few strategies backed by technology and research that can help manage the diabetes journey:

1. Use Technology To Lighten The Load: Continuous Glucose Monitoring (CGM) devices are game-changers for people with diabetes — offering real-time insights that help reduce stress and make daily management easier. These painless, prick free devices track your blood sugar levels every minute and generate visual trends, enabling you to act before your glucose levels become too high or too low.

2. Find balance through routine and joy: Burnout often stems from trying to do everything perfectly. Let go of perfection and  find your own balance.. Identifying the activities and health goals that matter most to you can make managing diabetes—and your overall well-being—feel more achievable and sustainable.

3. Stay active and focus on mindful eating: A mix of moderate intensity aerobic and resistance-based exercises like walking, yoga, swimming, dancing, weight training etc., for approximately 150 minutes per week, is often recommended for people with diabetes. Movement improves insulin sensitivity and releases endorphins that help reduce stress. Your meals matter too. Choose balanced diets and practice mindful eating.

Finally, make time for things you enjoy- whether it is spending time with someone, or pursuing a hobby. Focus on what matters the most – you can create a healthier and happier life.

A group of American researchers demonstrated that using the patient’s voice, artificial intelligence (AI) can assist in the early detection of laryngeal or voice box cancer.

Voice box cancer is a significant public health concern. An estimated 1.1 million instances of laryngeal cancer were reported globally in 2021, and the disease claimed the lives of about 100,000 people.

Human papillomavirus infection, alcohol misuse, and smoking are risk factors.

Depending on the tumor’s stage and location within the voice box, the prognosis for laryngeal cancer varies from 35% to 78% survival over five years when treated.

Researchers at Oregon Health & Science University have now demonstrated that artificial intelligence (AI) can identify anomalies of the vocal folds from speech sounds.

Similar to nodules or polyps, these “vocal fold lesions” can be benign, but they can potentially be the first signs of laryngeal cancer.

The scientists stated in the paper published in the journal Frontiers in Digital Health that these proof-of-principle results pave the way for a new use of AI, specifically the recognition of the early warning phases of laryngeal cancer from voice recordings.

Dr. Phillip Jenkins, a postdoctoral researcher in clinical informatics at Oregon, stated, “Here we demonstrate that we could use vocal biomarkers to distinguish voices from patients with vocal fold lesions from those without such lesions.”

Using 12,523 voice recordings of 306 people from North America, Jenkins and his team examined differences in tone, pitch, loudness, and clarity.

A small percentage came from individuals who had unilateral vocal fold paralysis, spasmodic dysphonia, benign vocal fold lesions, or known laryngeal malignancy.

The mean fundamental frequency (pitch), jitter (pitch variation within speech), shimmer (amplitude variation), and the harmonic-to-noise ratio (a measure of the relationship between harmonic and noise components of speech) were among the acoustic characteristics of the voice that the researchers concentrated on.

They discovered significant variations in the fundamental frequency and harmonic-to-noise ratio among men with laryngeal cancer, individuals with benign vocal fold lesions, and men without any voice disorders.

Although a larger dataset would show such disparities, they were unable to uncover any meaningful acoustic patterns among women.

According to the researchers, variation in the harmonic-to-noise ratio can be useful for early detection of laryngeal cancer, at least in men, and for tracking the clinical progression of vocal fold lesions.
