Pope Francis injured his right arm after suffering a fall earlier this week. According to the Vatican, while the 88-year-old pontiff did not break his arm, a sling was put on as a precaution. This incident comes just weeks after another fall on December 7, where he hit his chin on a nightstand, resulting in another, visible bruise. The pope's health has been a topic of ongoing speculation due to his age and medical history, which includes long bouts of bronchitis and mobility challenges. Often seen using a wheelchair or a cane, Francis also uses a walker within the Vatican's Santa Marta hotel, where he resides. Notably, his frailty has brought renewed attention to the risks of falls among elderly individuals and the steps one must follow to mitigate such falls.

Preventive Measures For Bone Health

A study published in Frontiers in Aging Neurosciences people get older, the bone density in the lower back and thigh bone decreases significantly. This raises the risk of osteoporosis (OP). Therefore it becomes pivotal to pay early attention to nutrition, exercise ability, vitamin D levels, and uric acid levels in older individuals to prevent Ostreopsis and mitigate fall risks. The risk of falls and bone injuries among elderly individuals underscores the importance of preventive measures for maintaining bone health and minimizing fall risks.

Elderly, particularly menopausal women, require a daily calcium intake of 1,200 mg, divided into two or more doses. This can be achieved through dietary sources such as dairy and non-dairy products or through supplements like calcium carbonate and calcium citrate. However, total daily calcium intake should not exceed 2,500 mg to avoid potential health risks.

Vitamin D is essential for calcium absorption and bone mineralization. While sunlight exposure helps synthesize vitamin D, older individuals often require supplements due to reduced skin synthesis and the limited availability of foods. Fortified milk and supplements containing 200–600 IU of vitamin D daily are recommended, with higher doses required for those with deficiencies. Severe cases may necessitate high-dose treatments, such as 50,000 IU weekly for up to three months, along with regular monitoring of calcium and vitamin D levels.

Regular exercise is vital for preserving bone mass and reducing fall risk. Weight-bearing activities, strength training, and balance exercises like brisk walking or skipping can enhance bone density and improve coordination. Experts recommend at least 30 minutes of moderate physical activity most days of the week, supplemented by strength training twice weekly. For individuals unable to engage in standard exercise routines, alternatives like vibrating platforms may help maintain bone health.

Falls remain a leading cause of fractures among individuals over 60. Addressing contributing factors such as balance issues, vision problems, and environmental hazards can significantly reduce risks. Preventive measures include regular vision checks, minimizing medications causing dizziness, improving home safety (e.g., installing railings and removing loose rugs), and wearing rubber-soled footwear. Hip protectors may also help mitigate the impact of falls.

US President Donald Trump has signed an executive order aimed at changing childhood vaccine recommendations, including moving toward separating the measles, mumps and rubella (MMR) vaccine into individual shots.

The executive order, titled “Delivering Gold Standard Childhood Vaccine Recommendations for Americans,” has sparked debate over how childhood vaccines should be administered and whether combination vaccines should instead be given separately.

Amid criticism of the move, HealthandMe spoke to public health experts to understand whether splitting the MMR vaccine offers any proven health benefit and what it could mean for children and vaccination coverage.

What Does Splitting MMR Mean?

Dr. Sabine Kapasi, Global Health Strategist and a UN Advisor, told HealthandMe that combination vaccines are more than a matter of convenience.

“Combination vaccines are not simply a matter of convenience. They can reduce the number of injections and healthcare visits required, support timely vaccination and help health systems reach children who may otherwise be missed,” she said.

“The more fragmented the pathway becomes, the more important it is to understand its impact on uptake, completion and equity,” Dr. Sabine added.

Dr. Rajeev Jayadevan, former President of IMA Cochin and Convener of the Research Cell, Kerala, also highlighted the practical disadvantage of requiring parents to make additional clinic visits when vaccines that can be administered together are separated.

Is Splitting MMR Healthier?

There is currently no adequate scientific validation for the argument that giving the MMR components separately is inherently healthier, according to Dr. Rajeev.

“The argument that splitting the shots is a healthier option does not have adequate scientific validation, because the body’s immune system routinely encounters numerous antigens simultaneously and effectively in everyday life,” he told HealthandMe.

Dr. Sabine emphasized that any change to childhood immunization policy should be based on evidence rather than simply altering an established schedule.

“Any change to childhood immunization policy should therefore be grounded in transparent evidence, rigorous safety and effectiveness assessment, and real-world data on vaccination coverage and completion,” she added.

Could More Vaccine Visits Increase Hesitancy?

Separating combination vaccines could make vaccination more cumbersome for families by requiring additional visits.

Dr. Sabine said vaccination programs operate within different health systems, meaning even small changes in scheduling can have implications for access, logistics, costs and continuity of care.

“The priority should remain consistent: designing immunization systems that are evidence-led, accessible and resilient enough to protect children across populations—not simply changing the schedule for the sake of changing it,” she said.

In a post on X US Senator Bill Cassidy, a physician, also criticized the executive order and warned that breaking up combination vaccines could mean children need more shots to receive the same protection.

“It will increase hesitancy and make children less safe,” he said, urging parents to discuss vaccination decisions with their child’s pediatrician.

Former White House COVID-19 Response Coordinator Dr. Ashish Jha said European countries do not routinely split the MMR vaccine into three separate shots. “No European country splits the MMR vaccine as 3 separate shots,” he said in a post on X.

He added that Russia and Tajikistan were historical partial exceptions but have since moved to full MMR vaccination.

Are There Any Potential Advantages?

Dr. Rajeev said one potential advantage of the new approach is the separation of vaccines into essential and optional categories.

He said this could give parents greater clarity about which vaccines are considered the highest priority and potentially help address some forms of vaccine hesitancy. The expert also pointed to US policy around childhood COVID-19 and influenza vaccines, saying that making these vaccines a shared decision between doctors and parents could be viewed as a progressive step.

For years, people living with Long COVID have described a strange combination of symptoms: severe fatigue, brain fog, memory problems, slowed thinking and a loss of motivation. Researchers may have found an important clue behind at least some of these brain symptoms.

A new study published in eBioMedicine found that people with Long COVID had 16% to 20% lower markers of dopamine nerve endings in key regions of the brain, with the average reduction of around 18%.

The findings suggest that the brain's dopamine system may be affected long after the initial COVID-19 infection has passed.

What Are The Study's Findings?

Researchers from the Centre for Addiction and Mental Health (CAMH) and the University of Toronto used PET brain scans to examine 24 adults with Long COVID and 24 healthy, age-matched individuals.

They focused on VMAT2, a protein found in nerve terminals that release dopamine. VMAT2 stores and packages dopamine inside nerve cells. Lower VMAT2 on the scans indicated reduced dopamine nerve-terminal density. However, it does not prove that dopamine neurons have permanently died.

The reductions appeared across three important regions of the striatum, which is involved in motivation, movement and thinking. Lower dopamine markers in the ventral striatum were associated with reduced motivation. Changes in the putamen were linked with slower movement, while changes in the caudate were associated with memory difficulties.

The Dopamine Factor

When dopamine production is disrupted, people can experience problems that go far beyond mood swings or low motivation.

The changes were also detected in people who had been living with Long COVID for as long as 4.6 years. This could help explain why some Long COVID patients report that even simple tasks feel unusually difficult or that they struggle to find the motivation to do things they previously enjoyed.

Long COVID is already known to involve a wide range of neurological symptoms, including fatigue, headaches, cognitive problems, anxiety and depression.

A 2026 review in Nature Reviews Neurology noted that approximately 6% of people who have experienced acute COVID-19 may develop this post-COVID condition.

Scope Of Treatment

The study does not mean that people with Long COVID have Parkinson's disease, nor does it establish that dopamine loss causes all Long COVID symptoms. The researchers also acknowledge that the study was small and that the findings show an association rather than proving cause and effect.

Still researchers say that the findings suggest that medications which enhance dopamine function, including dopamine precursors and drugs that reduce dopamine breakdown, could be investigated as potential treatments. They plan to launch a clinical trial targeting dopamine function in people with Long COVID.

More About Long COVID

Long COVID is a debilitating condition that can persist for months or even years after a SARS-CoV-2 infection. Long COVID is an infection-associated chronic condition marked by fatigue, cognitive impairment, exercise intolerance, and multisystem dysfunction.

It has affected an estimated 400 million people worldwide and continues to have significant health, social, and economic consequences. Despite the ongoing risk, prevention strategies have received relatively little attention.

Dry or burning eyes are often brushed aside as side effect of ageing. But new research suggests that for postmenopausal women, the problem may be more than just eye irritation.

A recent study in Post Reproductive Health found that postmenopausal women had more severe signs of dry eye disease (DED) than both younger women and men in the same age range.

Researchers say the condition is caused largely by tear-film instability and dysfunction of the meibomian glands, the tiny glands in the eyelids that produce the oily layer of tears.

The study included 319 participants: 102 postmenopausal women, 105 age-matched men and 112 younger healthy women.

Researchers assessed symptoms, tear production, tear-film stability, damage to the eye surface and meibomian gland function.

Postmenopausal women had the highest rate of severe dry eye, affecting 24.5%, compared with 16.2% of age-matched men and 18.8% of younger women.

They also had higher scores for dry-eye symptoms, more straining of the of the ocular-surface, shorter tear-break-up time and greater meibomian gland dysfunction. 20.6% of postmenopausal women reported burning.

The connection between eyes and menopause lies in the significant hormonal changes women face as they enter menopause.

The ocular surface, lacrimal glands and meibomian glands are affected by sex hormones, including oestrogen and androgens. When hormone levels change during and after menopause, these tissues may also function differently.

One of the important consequences of menopausal hormonal shifts is the disruption of the tear film. The tear film is like a thin protective coating over the eye. It contains an oily outer layer that slows evaporation. The meibomian glands produce this oil.

When these glands do not work properly, tears can evaporate too quickly. Doctors call this condition evaporative dry eye.

Dry Eye Does Not Mean The Eyes Have Stopped Producing Tears

Dry eye does not necessarily mean the eyes have stopped producing tears. In many postmenopausal women, the tears may not remain stable on the eye for a long time.

As the oily layer becomes impaired, tears evaporate faster. This can increase tear concentration, trigger inflammation and damage the ocular surface, creating a cycle of dryness and irritation.

Hormonal changes during menopause may contribute to this process, although researchers are still working to understand exactly how individual hormones influence dry eye.

A 2026 review also highlights increasing evidence that hormonal changes may interact with immune and inflammatory pathways on the ocular surface, rather than simply reducing tear production.

What Symptoms Should Postmenopausal Women Watch For?

Persistent burning, itching, grittiness, redness, light sensitivity, watery eyes or fluctuating vision can all occur with dry eye disease.

The latest study also found that clinical signs of disease were more severe in postmenopausal women even though symptom scores did not always differ significantly from other groups. This finding makes eye examinations particularly important during and after menopause.

The researchers concluded that recognising these differences could improve diagnosis and help doctors better understand the hormonal contribution to dry eye disease.
