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

Are you someone who can spend hours scrolling through short videos on Instagram, YouTube or TikTok? A new study suggests that watching preferred short videos may temporarily quiet brain regions involved in self-control and monitoring, offering a possible clue to why it can be so hard to stop.
Short Videos May Quiet Brain’s Self-Control Network
The research, published in the journal NeuroImage, found that watching preferred short videos may temporarily suppress activity in parts of the brain involved in cognitive control. This effect may also be linked to levels of the brain chemical glutamate.
The study focused on the dorsal anterior cingulate cortex (dACC) and dorsolateral prefrontal cortex (dlPFC). Both are key regions of the cognitive control network, which becomes active during tasks that require mental effort, attention and self-regulation.
Researchers from Zhejiang University in China found that both the dACC and dlPFC showed significant deactivation when participants watched preferred videos to completion, compared with less-preferred videos that were stopped early.
The liked videos significantly reduced activity in both brain regions linked to cognitive control. When participants watched videos they chose to continue, activity in the dACC and dlPFC fell below normal resting levels.
However, disliked videos showed a different pattern. Activity in the dACC remained close to normal, while the dlPFC was still suppressed. Meanwhile, the visual cortex remained active during both types of videos, suggesting the changes were linked to the viewing experience rather than simply looking at a screen.
The small study of 56 participants also examined whether resting levels of two important brain chemicals could help explain differences in how participants’ cognitive control networks responded during short-video viewing.
Glutamate is the brain’s main excitatory neurotransmitter, helping increase neural activity. Gamma-aminobutyric acid (GABA) is the brain’s main inhibitory neurotransmitter, helping reduce or regulate neural activity.
The researchers found that resting-state glutamate levels in the dACC were associated with the extent of brain deactivation. Higher glutamate concentrations were linked to less suppression of activity in both the dACC and dlPFC.
Functional connectivity between the dACC and dlPFC also increased during video viewing, particularly when participants watched their preferred videos.
The researchers said the findings provide new evidence that immersive viewing of preferred short videos can deactivate the cognitive control network and that individual differences in this response may be linked to glutamate metabolism.
They suggested that the findings could help improve understanding of how digital media consumption interacts with neurochemical processes involved in self-regulation and may offer insights into the neural mechanisms behind excessive short-video use.
The study, however. does not establish that short-video viewing directly causes a loss of self-control or addictive behavior.
Previous research has linked excessive short-video use with changes in attention, focus and mental well-being.
Studies in Nature Communications and research from the American Psychological Association suggest that highly stimulating, rapidly changing content may encourage constant novelty-seeking and make sustained attention more difficult.
Potential effects include:
Short videos are not inherently harmful, but excessive or compulsive scrolling can become a concern when it interferes with sleep, work, studies or daily life.

Breast cancer is now the most commonly diagnosed cancer among women in India, representing a significant and growing public health concern. According to recent estimates, India recorded approximately 221,757 new breast cancer cases in 2022, making breast cancer the most common cancer among women and accounting for nearly one-fourth of all female cancers in several urban populations1.
Rising urbanisation, lifestyle changes, delayed childbirth, and increasing life expectancy have contributed to the growing incidence. Despite advances in awareness and screening, many women continue to be diagnosed at later stages, underscoring the need for effective, accessible, and patient-centric treatment approaches.
As cancer care evolves towards more personalised treatment, brachytherapy is emerging as a targeted alternative that delivers radiation with greater precision.
Unlike conventional radiation, which passes through normal tissues before reaching the target, brachytherapy focuses treatment directly on the tumour bed. This precision helps maximise treatment effectiveness while reducing potential side effects.

One of the most significant applications of breast brachytherapy is Accelerated Partial Breast Irradiation (APBI). In selected patients with early-stage breast cancer, the risk of recurrence is highest around the original tumour site. APBI targets only this region rather than treating the entire breast.
This focused approach helps protect healthy breast tissue and nearby organs such as the heart and lungs. Advanced imaging and treatment-planning technologies further enhance personalisation by allowing radiation doses to be tailored to the patient's anatomy and tumour characteristics.

A major advantage of brachytherapy is the shorter treatment schedule it offers. Conventional radiation therapy may require daily sessions for three to six weeks, whereas brachytherapy-based APBI can often be completed within a few days.
For patients travelling long distances to access specialised cancer care, this can reduce both the logistical and financial burden of treatment while minimising disruptions to daily life.
As survival rates improve, quality of life has become a key consideration in breast cancer care. Brachytherapy's targeted approach reduces radiation exposure to healthy tissues and has been associated with favourable cosmetic outcomes.
By combining precision, convenience, and effectiveness, brachytherapy represents an important step towards personalised breast cancer treatment, offering appropriately selected patients an opportunity for effective care with potentially fewer side effects and improved overall treatment experience.

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.
