Regular internet usage is associated with lower risk of dementia in older people

1. The prevalence of dementia is increasing with an increase in longevity. Prevention is preferred as there is no cure for Alzheimer's disease.
#dementia #MedTwitter #NeuroTwitter #Internet
2. 18,154 adults aged 50-65 were followed up for a maximum of 17.1 (median=7.9) years.
Regular internet usage was associated with approximately half the risk of dementia compared to non-regular usage.
Educational status did not play any role in this association.
3. In addition, additional periods of regular usage were associated with significantly reduced dementia risk.
However, estimates for daily hours of usage suggested a U-shaped relationship with dementia incidence. The lowest risk was observed among adults with 0.1-2 hours of usage
4. The risk of dementia started to increase if internet was used for >2 hours daily, with maximum risk being seen at 6-8 hours of daily internet use.
The sample size was small to make a definitive conclusion on this aspect.
5. Keeping brain active- by playing sudoku or solving crossword puzzles, or reading a book, writing a story, or learning a new skill- is known to reduce the risk of dementia.
Internet can provide opportunities to keep the brain active and engaged via an "online" mode.
6. Take home message
*Internet use on a regular basis in people aged 50 or more is associated with lower rates of cognitive decline and dementia.
*However, prolonged daily internet use may increase the risk of dementia (more research is needed to confirm this aspect).

Stroke is the third leading cause of death and disability (the first two are heart attack and cancer). Treatment of #stroke is time-bound, and less than 10% of people receive the clot-buster drug therapy. Therefore, most people who survive a stroke are left with disabilities.
12 preventive strategies can be easily followed, and they have the potential to significantly reduce one's chances of suffering from stroke.
These are:
1. Sleep for 7-9 hours at nights;
2. 150 min of moderate-vigorous exercise per week;8000-10000 steps/day;
3. Healthy food;
4. Maintain ideal body weight;
5. Minimize the daily sitting duration to less than 6 hours;
6. Quit smoking;
7. Abstain from alcohol;
8. Reduce stress;
9. Maintain BP less than 120/80 mmHg;
10. Target HbA1C less than 5.7% (the lower, the better);

2. Full fat milk consumption was associated with a higher risk of cardiovascular diseases (CVDs) and death in people with Type 2 diabetes (T2D).
Low fat milk consumption, on the other hand, reduced the risk of CVDs and death.
3. Increase in consumption of coffee, tea or low fat milk (versus no change in consumption) after the diagnosis of diabetes, resulted in further reduction in the incidence of cardiovascular diseases and death.

Most melatonin gummies in US are inaccurately labelled

1. Melatonin gummies are routinely given to children for sleep, stress and relaxation.
Melatonin is not approved by FDA for use in children, and hence #melatonin gummies are bought OTC or online.
#MedTwitter #sleep
2. Pediatric melatonin ingestions in US increased 530% from 2012 to 2021 and were associated with 27 795 emergency department and clinic visits, 4097 hospitalizations, 287 intensive care unit admissions, and 2 deaths.
3. In a recent study, 25 melatonin gummy brands were analyzed. Twenty-two of 25 products (88%) were inaccurately labeled, and only 3 products (12%) contained a quantity of melatonin that was within ±10% of the declared quantity.

"The grass is always greener on the other side"

All is not bright for doctors living abroad. I have had multiple opportunities to settle abroad with salaries offered between 5-20 times (as compared to that of India's), but I chose to settle in India, and I have never regretted.
2. There are multiple reasons why doctors staying back in India could be happier:
*The joy of seeing a fellow Indian (many of whom can't afford expensive medical care) get better is manifold greater than the joy of treating a foreigner.
*Comforts of living in India are greater+
3. +as one can afford to hire cook, babysitter or other helps with lesser salaries.
*I know of doctors living abroad, whose parents (staying in India) are old & have disabling illnesses. Children feel miserable and helpless, while remotely managing their parents' illnesses.

One in five people suffer from hearing loss

1. Yes, you heard it right.
This information was obtained by a study published in The Lancet journal in Mar 2021.
An estimated 1·57 billion people globally had hearing loss in 2019.
doi.org/10.1016/S0140-…
#MedTwitter
2. Although hearing loss is common in old ages, globally 70 million children aged 0–15 years also live with this condition. Otitis media and meningitis are risk factors for hearing loss in children.
38% of people with hearing loss were less than 50 years old.
#HearingLoss
3. When unaddressed, childhood hearing loss can affect spoken language development, literacy skills, and education, which might affect cognition and social wellbeing.
Older people with hearing loss have a higher risk of developing #dementia, including #AlzheimersDisease.

Eating walnuts for 6 months was associated with better sustained attention and intelligence scores in teenagers

1. A total of 771 healthy teenagers aged 11–16 years were randomized into two equal groups (intervention or control).
#MedTwitter #healthyfood Image
2. The intervention group received 30 g/day of raw walnut kernels to be incorporated into their diet for 6 months. Walnuts are rich sources of omega 3 fatty acid, alpha linolenic acid (ALA)
doi.org/10.1016/j.ecli…
3. Findings of the study:
Significant benefits were found for attention, fluid intelligence, and ADHD symptoms, meaning that consuming 30 g of walnuts daily for 100 days, or more, improved these neuropsychological outcomes.
