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.

What the Report Says

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.

Why Older People Fall and Break Bones More Easily

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.

Better Ways To Protect Your Bone Health

USPSTF recommends a few better ways to protect your bone health and prevent broken bones and falls.

Walk Regularly

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.

Do Strength Training

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.

Practice Balance

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.

Check Your Medicines

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.

Eat Enough Protein

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.

Get Your Eyes Checked

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.

Get Enough Sleep

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.

Make Your Home Safe

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

Parkinson’s disease (PD) symptoms differ between women and men, a new study has found, with potential implications for treatment.

Presented at the 2026 International Congress of Parkinson’s Disease and Movement Disorders in Seoul, the study found that women experienced more severe motor complications and depression. Men, however, had greater cognitive impairment.

“Sex differences in movement disorders remain understudied and undervalued despite having an important impact on clinical outcomes in both real-life and clinical trial settings,” said Dr. Marina Picillo, assistant professor of neurology at AOU San Giovanni di Dio e Ruggi d’Aragona.

What Did The Study Find?

Researchers retrospectively analyzed 10 years of clinical data from more than 10,000 Parkinson’s patients examined at a movement disorders clinic in Germany.

The findings showed that women had a greater burden of motor complications and depression. Men were more likely to experience cognitive impairment, REM sleep behavior disorder (RBD) and loss of smell.

“By analyzing data for more than 10,000 PD patients, this study confirmed that depression is more common in women, while RBD, worse cognition, and poorer olfaction are more prevalent in men,” Picillo said. “With good representation of women (40%), it also confirmed a greater female burden of motor complications.”

How Could The Findings Help?

The findings highlight the need to account for sex differences in Parkinson’s disease management and clinical trial design, particularly given the historical underrepresentation of women in neurological research. However, the factors underlying these differences remain unclear.

Picillo stressed that considering sex differences when tailoring treatment and designing clinical trials could be an important first step toward precision medicine in Parkinson’s disease.

“This would be the very first, basic step for boosting precision medicine in PD,” she said.

What Is Parkinson’s Disease?

Parkinson’s disease is a progressive neurodegenerative disorder caused by the loss of dopamine-producing nerve cells in the brain.

Common symptoms include tremors, muscle stiffness, slowed movement and impaired balance. As the disease progresses, patients may have difficulty walking, speaking and performing everyday tasks.

The condition can also cause cognitive impairment, depression, anxiety, sleep disturbances, pain and swallowing difficulties, affecting patients’ independence and quality of life. Although it primarily affects older adults, younger people can also develop Parkinson’s disease.

Global Burden Of Parkinson’s Disease

Parkinson’s disease affected an estimated 11.9 million people worldwide in 2021. The number is projected to reach 25.2 million by 2050, a 112% increase.

Can Parkinson’s Disease Be Prevented?

There is currently no established way to prevent Parkinson’s disease. However, research suggests that certain lifestyle and environmental factors may influence disease risk.

• Physical activity: Regular exercise supports overall health, although its role in preventing Parkinson’s disease remains under investigation.
• Diet and nutrition: A balanced diet supports brain health, but no specific diet has been proven to prevent the disease.
• Environmental factors: Exposure to certain pesticides and other environmental pollutants has been associated with Parkinson’s disease risk. Reducing harmful exposures may help address potential risk factors.

A US lawsuit has accused feminine hygiene brand Carefree of exposing women to perfluorooctanoic acid (PFOA), a chemical linked to certain cancers. The complaint alleges that users developed health problems ranging from yeast infections to liver disease.

The lawsuit, filed in Los Angeles County Superior Court, claims the panty liners contained PFOA, a member of the per- and polyfluoroalkyl substances (PFAS) group, New York Post reported.

The women in the suit claim they suffered health problems, including breast, ovarian and kidney cancer; thyroid disease; chronic inflammation; infections; high cholesterol and immune disorders.

Others allegedly suffered reduced fertility or infertility, while the lawsuit claims the women now live in fear of developing cancer because of their alleged exposure.

“Each plaintiff suffered physical, mental, and emotional pain and suffering, anxiety over her diagnosis and treatment, and loss of enjoyment of life,” the papers state.

But can chemicals in panty liners pose a health risk? Scientific research has detected potentially harmful substances in menstrual products, raising questions about repeated exposure.

What Are PFOA And Forever Chemicals?

PFOA is a synthetic chemical belonging to the PFAS family, commonly known as forever chemicals because some can persist in the environment and human body for years.

Research has linked PFOA exposure to an increased risk of kidney and testicular cancers. Studies have also associated exposure with health concerns involving cholesterol, thyroid function and the immune system.

However, the risks depend on the chemical, the level and duration of exposure, and how it enters the body. The allegations against Carefree do not, by themselves, establish the extent of exposure from panty liners or the resulting health risks.

What Does Research Say About Chemicals In Panty Liners?

A February study published in Science of the Total Environment detected endocrine-disrupting chemicals (EDCs), including phthalates, bisphenols and parabens, in sanitary pads and panty liners.

Detection frequencies ranged from 75% to 100% in panty liners and 50% to 100% in sanitary pads. Phthalates were more prevalent in liners, while bisphenols were detected more frequently in pads.

The researchers estimated daily exposure doses of 2–20 nanograms per kilogram of body weight under normal skin-absorption assumptions, rising to 8–80 nanograms per kilogram under alternative exposure assumptions.

The findings highlight menstrual products as a potential source of chemical exposure, particularly when use is repeated over long periods and exposure occurs alongside other sources.

Some endocrine-disrupting chemicals have been investigated for their potential effects on hormonal and reproductive health. However, detecting these substances in menstrual products does not establish that using the products causes cancer.

More research is needed to determine how much of these substances is absorbed during normal use and whether the resulting exposure poses a measurable health risk.

Chemical exposure is not the only concern associated with panty liner use. Fragrances and other ingredients may trigger allergic reactions or contact dermatitis in people with sensitive skin.

Prolonged moisture and friction can also aggravate irritation around the vulva. Although liners do not necessarily cause bacterial or yeast infections, continuous use may cause discomfort in some people.

Persistent itching, unusual discharge or recurring irritation should be assessed by a healthcare professional.

How To Use Panty Liners More Safely

• Choose unscented liners: Fragrances may irritate sensitive skin.
• Change them regularly: Replace liners when damp or soiled to reduce prolonged moisture and friction.
• Avoid unnecessary use: Skip liners when you do not need them, particularly if they cause irritation.
• Check product information: Look for disclosures about materials and whether PFAS are intentionally added. Such claims do not guarantee the complete absence of these chemicals.
• Seek medical advice: Consult a healthcare professional if irritation or other symptoms persist.

Auto antibodies that target the body’s DNA-repair process may provide researchers with some clues about why some children develop cancer. It has opened new avenues for early detection and appropriate treatment, according to a study published in Frontiers in Immunology recently.

A team of researchers from Norway, through the study, identified that children with cancer were more likely to have antibodies that target proteins tasked with repairing damaged DNA.

In a separate group of children whose blood samples had been collected years before they developed cancer, those who were later diagnosed were about eight times more likely to carry these antibodies than their peers who remained free of cancer.

The findings suggest that these antibodies could be an important marker of early indicator of cancer risk. However, the researchers state that further studies are needed to prove whether the antibodies contribute to cancer development and whether they can reliably predict the disease years before.

How Antibodies Interfere With DNA Repair?

Antibodies are proteins that are generated by the immune system. They help recognise and neutralise foreign bodies, like viruses and bacteria.

Sometimes, however, the immune system produces autoantibodies, which mistakenly target the body’s own proteins.

The study found that some children with cancer had elevated levels of autoantibodies against six proteins involved in DNA repair. They are RAD52, NUMA1, ALKBH7, APBB1, UNG and MGMT.

DNA repair is essential because cells constantly go through damage that can lead to errors into their genetic material. When these errors are not corrected, mutations may accumulate and gradually contribute to cancer.

The researchers proposed an unproven theory that the antibodies might enter cells and bind to protein responsible for DNA repair, interfering with their normal function.

Their laboratory experiments provided evidence that these antibodies can enter living cells and localise to a cellular compartment called the TIGER domain.

“We showed that many children with various types of cancer have antibodies against some of their own DNA repair proteins. We also demonstrated that such ‘auto-antibodies’ can enter live cells and bind to – and probably inhibit – the activity of these essential proteins,” said corresponding author Dr Ola Myklebost, emeritus professor of molecular oncology at the University of Bergen.

If the antibodies do impair DNA repair, they could contribute to the accumulation of genetic damage. However, this mechanism has not yet been conclusively observed in humans.

Could A Blood Test Predict Cancer Years In Advance?

To investigate whether the antibodies appeared before cancer diagnosis, the researchers examined blood samples from 59 children who participated in two British long-term studies: the Avon Longitudinal Study of Parents and Children and Born in Bradford.

Half of the children were subsequently diagnosed with cancer before the age of 30, while the other half had not developed the disease. On average, the blood samples from those who later developed cancer had been collected approximately six years before diagnosis.

“Although this cohort is small, it was the best we could find internationally,” Myklebost said.

He added that children who later developed cancer were about eight times more likely to have antibodies against at least one key DNA-repair protein.

The researchers analysed samples from a broader group of 375 healthy individuals and patients, alongside cancer samples from adults and children with sarcoma or acute lymphoblastic leukaemia.

Childhood cancers are often biologically different from adult cancers. Unlike many adult malignancies, which can accumulate mutations over decades, paediatric cancers may arise in developing cells with fewer accumulated genetic changes. The researchers believe the immune system could play an important role in some cases.

However, the findings do not establish that the antibodies cause cancer. The study also cannot determine how accurately an antibody test would predict future disease in the general population.

The researchers are now investigating whether these antibodies affect DNA repair in laboratory-grown cells and plan to study their potential cancer-causing effects in animal models.

“At present we are investigating the effect of patient antibodies on the repair of induced mutations in cultured cells. Ultimately, we hope to clone white blood cells that secrete such auto-antibodies, and test for any cancer causing effects in mice to definitively prove our hypothesis,” Myklebost said.
