Longer daytime napping is associated with new-onset heart failure in older people

1. Disrupted nighttime sleep is associated with heart failure (HF).
A prospective study looked at the association between daytime napping and incident HF during follow up.
#napping #HeartFailure
2. Participants who napped longer than 44.4 minutes (ie, the median daily napping duration) showed a 73% higher risk of developing incident heart failure than participants who napped <44.4 minutes.
3. Participants who napped >1.7 times/day showed a 120% increase in new onset HF compared with participants who napped <1.7 times/day.
These associations persisted after adjustment for covariates, including nighttime sleep, comorbidities, and cardiovascular disease/risk factors.
4. Conclusions:
*Longer and more frequent objective napping predicted elevated future risk of developing incident heart failure.
*Future direction: The mechanisms involved in the association of daytime napping (of >44.4 min) & higher risk of heart failure need to be studied.

When medicines fail, do prayers & positive frame of mind help?
1. Mr Raja to me- “Dr, I won’t die in 6 months. Prescribe the best medicines; I am sure I’ll defeat my disease.” His mother too echoed his words- “Dr, I love my son, and will always stand by his side, come what may.”
2. Mr Raja had consulted me with headache of 10 days duration. While going to a spa for head massage, he thought of getting an opinion of a neurologist. As it was a new-onset headache, I ordered for a CT scan, which showed a mass lesion.

3. Further investigations, including MRI brain, followed by brain biopsy confirmed it to be a high grade glioblastoma multiforme (GBM), an aggressive brain cancer with average survival of 12-18 months.

Daytime napping for >30 minutes increases the risk of atrial fibrillation
1. Some nap during daytime as a habit, whereas a few try to catch up on lost sleep at nights with some daytime napping.
However, there is some bad news for those napping >30 minutes during daytime.
#sleep
2. In a recent study, compared to short daytime nappers(<30 min), those who snoozed for 30 minutes or more per day had a nearly doubled risk of developing atrial fibrillation (AF).
Meanwhile, compared with short nappers; risk was not elevated in those who avoided #napping.
3. Further analysis was done based on the nap duration.
Compared with those who napped for more than 30 minutes per day, those who napped for less than 15 min had a 42% lower risk of developing atrial fibrillation; while those who napped for 15 to 30 min had a 56% reduced risk.

1. Today at work: Conversed with patients in Tamil, Telugu, Bangla, Hindi, English, Somali & Arabic during ward/ICU rounds & OPD.
Brought smiles on patient's faces as well. I love interacting with people/patients in their own languages as they love listening to own languages. twitter.com/i/web/status/1…
2. I have seen agitations against various languages in many states, which are futile. It is always good to learn more languages, as it is a win-win situation.

3. Speaking two languages, moreover, delays the age of onset of dementia by an average of 4.5 years. This benefit is seen in educated as well as illiterate people. doi.org/10.1212/01.wnl…

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);

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

Sugar sweetened beverages (SSBs) are associated with higher risk of heart diseases & death in people with type 2 diabetes (T2D)

1. Drinking coffee, tea or plain water, on the other hand, reduced the risk of heart diseases and death, in a long-term prospective study.
#Medtwitter Image
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.
