Bone Health In Older Adults (Credit-Canva)
Strengthening your bones is not something that can happen overnight, it takes years for your body to build strong bones and even then, it is natural for them to lose their dexterity. All you can do is keep your body healthy to make sure it is prepared for any unexpected situations. For years, many older adults have been told to take vitamin D and calcium supplements to keep their bones strong and prevent falls. However, a new report from U.S. Preventive Services Task Force (USPSTF) is changing that advice. This report suggests that for most older people, these supplements don't actually prevent falls or broken bones. This might be surprising news, we must understand why falls happen more often as we age, what vitamin D and calcium do in the body, and most importantly, what you can do to stay safe and prevent fractures.
According to the report, vitamin D supplements don't seem to help prevent falls or broken bones for most people over 60. They also found that these supplements, especially with calcium, might increase the risk of kidney stones. This report doesn't mean people with weak bones (osteoporosis), low vitamin D, or who take vitamin D for other health reasons shouldn't take it. It just means that for most healthy older people, these supplements don't prevent falls and fractures.
There are many reasons why older people are more prone to breaking their bones. Our bones are strongest when we're in our 20s and 30s, and they get weaker as we age so naturally, they can break easily. It can also be harder to move around as we get older, sometimes because of problems like arthritis this can affect how we walk and make us less steady.
There are also different issues like neuropathy, which is a nerve problem that can also make it harder to feel your feet and keep your balance. Eyesight is also a culprit as it can cause you to feel dizzy and fall. Some medicines can also make people feel unsteady, and older people often take more medicines than younger people. Low vitamin D itself can also increase the risk of falls, so keeping vitamin D levels up is still important.
USPSTF recommends a few better ways to protect your bone health and prevent broken bones and falls.
Regular walks strengthen your muscles and bones, which helps you stay steady on your feet. It is as simple as practice makes perfect so the more you walk, the better it is. Walking also improves your balance, making you less likely to fall.
Strength training, like lifting weights or using resistance bands, makes your bones stronger and helps prevent fractures if you do fall. It is like a safety cushion, but you must be careful while doing so because it can lead to injuries if done too much.
Activities like tai chi, Pilates, and yoga can improve your balance and coordination, making you more stable and less prone to falls. These can also help you improve your muscle flexibility and strength that in turn helps your body be stronger.
If you have osteoporosis, talk to your doctor about medications that can help strengthen your bones and lower your risk of fractures. Many medications can also have unsavory side effects like weakened joints, losing muscle strength, etc.
A proper diet goes a long way when it comes to your entire body health. So to keep up with your body’s nutrition and muscle health, eat more protein along with a balanced meal that includes loads of fiber, healthy fats and carbs.
Having poor eyesight can be difficult, not only does it make life difficult without glasses, but it also increases the possibilities of getting into minor accidents like bumping into people and missing objects placed in front of us.
Getting enough sleep is also important because when you are not sleeping, you get disoriented and can ignore even obvious things like the last stair in the staircase. Make sure you get enough sleep to keep you fresh and focused.
There are many things that can cause you to have accidents, even in your home. To avoid such falls, make sure there are no lose ends like crooked floor panels, rugs that are sticking out or protruding furniture that can hurt your knees

Longevity expert and multi-billionaire Bryan Johnson has revealed another health condition affecting him. This time, it is meibomian gland dysfunction (MGD).
Johnson also said that the largely asymptomatic condition affects nearly 90 percent of adults over 40. The condition can "lead to permanent eye damage" and also affects younger people because of increased exposure to screens.
“I just learned that I have meaningful meibomian gland dropout. This is why my eyes are irritated,” Johnson said in a post on social media platform X.
“The dropout leads to evaporative dry eye disease, which triggers vision degradation such as blurred text, glare at night, light sensitivity, and neuropathic ocular pain. Left long enough, it can scar the cornea and permanently damage vision,” he added.
Meibomian gland dysfunction happens when the tiny oil glands in the eyelids become blocked or produce poor-quality oil. This prevents enough oil from reaching the tears, causing them to dry up too quickly.
Major triggers include aging, hormonal shifts, screen use, and skin or eye inflammation, according to Cleveland Clinic.
Johnson explained that there are about “60 meibomian glands per eye, split across the upper and lower lid. They are like pores, secreting nourishing oil (meibum) onto your tear film to prevent rapid evaporation.”
He noted that the glands can become dysfunctional due to conditions or factors including "age, androgen deficiency, menopause, hormone replacement, oral contraceptives, isotretinoin, antihistamines, SSRIs, tricyclics, beta blockers, diuretics, anticholinergics, preserved eye drops, incomplete blinking, reduced blink rate, screen use, contact lens wear, and ocular rosacea".
When these glands become clogged, the meibocytes can die, and the gland can eventually drop out. Johnson said conventional medicine considers total gland dropout irreversible.
Why Can MGD Go Unnoticed?
Importantly, Johnson said that MGD can remain asymptomatic during its initial stages. When symptoms appear, the condition can resemble ordinary dry eye, allowing it to worsen and lead to permanent gland dropout.
Advanced MGD can also numb the cornea, further masking subjective symptoms as the disease progresses.
How Did Bryan Johnson Detect MGD?
Johnson's MGD was detected after he went to the doctor for a chalazion or stye, a painful, red bump on the edge of the eyelid.
He also mentioned undergoing diagnostic tests, including the Schirmer test and infrared meibography.
How Is Johnson Treating MGD?
Johnson began treatment with in-office intense pulsed light (IPL), radiofrequency (RF), and an experimental intraductal probing, known as the Maskin protocol, to address inflammation and physically reopen clogged glands.
The eye-light device combines IPL with 630-nm red low-level light. The proposed mechanism involves stimulating mitochondrial ATP production in meibocytes and reducing inflammation around the eyes.
The probing therapy involved using 1-mm, 2-mm, and 4-mm probes, which were inserted into each gland orifice.
“My doctor then expressed my glands, using a roller device to expel any buildup and kickstart the gland’s natural expression. This is really painful. Brings you to tears,” Johnson said.
Along with IPL, RF, and probing, he was also using warm eye compresses twice a day, in the morning and at night.
“With this protocol, we’ve seen a 30% improvement in meibomian gland function (using imaging). My glands look healthier, eye irritation has lessened, my subjective symptoms have subsided, and when we probe now, we encounter minimal fibrotic resistance (popping),” he said.
Signs of MGD to Watch For
Johnson listed several symptoms and warning signs to watch for, including:
Any of these symptoms, particularly after age 40, may warrant a gland examination, Johnson said.

August 18 marks World Breast Cancer Research Day, a day that reminds us that every major breakthrough in cancer care has its roots in research. The medicines that are prescribed, the diagnostic technologies that we use, the targeted therapies that we offer and our growing understanding of why cancers develop and spread, are all outcomes of regular scientific research.
India carries one of the world's largest cancer burdens. According to IARC's GLOBOCAN 2022 estimates, India recorded approximately 1.41 million new cancer cases and more than 916,000 cancer deaths in 2022. Breast cancer alone was the leading cancer among Indian women and also the leading cancer overall.
India as a country, has a large and diverse patient population, significant clinical expertise, strong medical institutions and a pharmaceutical industry with enormous manufacturing capabilities. But there is a crucial gap between manufacturing what the world has already discovered and researching newer medical opportunities.
A significant proportion of cutting-edge cancer research continues to emerge from countries with substantially larger and more established research ecosystems. When scientific discoveries, new molecules, diagnostic technologies or treatment approaches are developed elsewhere, Indian patients benefit from them at a later stage.
We have limited institutes that have made important contributions to cancer care and research. But considering India's population and cancer burden, the scale of research infrastructure needs to expand substantially. We need more dedicated cancer-research institutes, stronger university hospital industry collaborations, modern laboratories, biobanks, genomic databases, data-science capabilities and trained physician-scientists.
Cancer is not just one disease. It comprises of multiple biological subtypes, and the way a tumour behaves can vary significantly between individuals and populations. Therefore, India needs research that focusses specifically towards Indian patients.

India has a formal Clinical Trials Registry, and the registry currently records more than 100,000 trials across areas of medicine.
For eligible patients, participation in an appropriate clinical trial may provide access to an investigational therapy or treatment strategy that is not yet routinely available. Clinical trials generate evidence that can improve future treatment for thousands or millions of patients.

We need to create an ecosystem that moves from discovery to translation to patient care. That means incentivizing research institutions and researchers, supporting young physician-scientists, strengthening public-private partnerships and making it easier for promising discoveries to move from laboratories into clinical development.
We need to have an ecosystem, where healthcare research, particularly research addressing diseases with an enormous Indian burden should receive a much greater and more targeted share of national research investment. A large, diverse population can generate valuable real-world evidence. Large patient cohorts can help researchers understand disease patterns. Indian genetic and molecular data can help answer questions that may not be adequately addressed through studies conducted in other countries.
India has already demonstrated that it can serve the world as a pharmaceutical manufacturing powerhouse. We should look at also becoming the research hub for the world by combining our pharmaceutical manufacturing strength, clinical expertise, technology capabilities and patient population.
The opportunity is already in front of us.
What we need now is the policy ambition to implement it.

If you believe having a healthy body mass index (BMI) means you have a low risk of heart disease, you may be wrong. A new study suggests that abdominal fat may predict cardiovascular disease risk better than BMI alone.
The study, published in the Journal of the American College of Cardiology (JACC), found that failing to account for waist circumference (WC) or waist-to-hip ratio (WHR) may lead to misclassification of cardiovascular disease risk.
“Indeed, it appears that WC and WHR reclassify risk defined by traditional BMI thresholds,” said Michael J. Blaha, director of clinical research at the Johns Hopkins Ciccarone Center for the Prevention of Cardiovascular Disease.
“We saw individuals with clinically determined normal weight who had elevated central adiposity and high WHR, associating them with higher risk across most outcomes,” Blaha added.
BMI is calculated by dividing weight in kilograms by height in meters squared and is commonly used to diagnose overweight and obesity. However, BMI does not show where body fat is distributed.
The study examined whether adding WC and WHR to BMI could better predict future cardiovascular risk. Researchers looked at more than 260,000 people over an average of 20 years. They found that central adiposity could identify cardiovascular risk that BMI alone may miss.
Among people classified as having normal weight by BMI:
People with normal weight or overweight who had clinically defined high WC or WHR had a 15%–50% greater risk for most heart problems.
People with obesity and low WC did not have a significantly different risk of outcomes compared with those who had normal weight and low WC, except for all-cause mortality, for which their risk was significantly lower.
“Our findings emphasize the critical role of identifying elevated central adiposity, even in individuals with a normal BMI or with a BMI in the overweight range. Relying solely on BMI may result in misclassification of cardiovascular risk across a wide range of cardiovascular outcomes,” said Zeina A. Dardari, lead author of the study.
“We encourage clinicians to consider central adiposity distribution across the entire BMI spectrum when evaluating cardiovascular risk in primary prevention settings,” she added.
The researchers did not have information on several factors that can influence cardiovascular disease risk, including:
The study also included only one assessment of waist circumference and waist-to-hip ratio. This limited the researchers' ability to understand how changes in abdominal fat accumulation over time may influence cardiovascular disease risk.
