Does habitual #Coffee consumption increase the blood pressure (BP)?

1. Coffee is the most widely consumed drink (after water) and coffee lovers need clarity whether it is safe in all aspects. Does it raise the BP? Is coffee safe for people with hypertension (high BP)? Let us see
2. No added risk of high BP
The results of numerous studies and meta-analyses indicate that "moderate and habitual coffee consumption does not increase" and may even reduce the risk of developing arterial #hypertension.
doi.org/10.1007/s11906…
3. Coffee can be safely consumed by people with high BP
Moderate "habitual coffee consumption in hypertensive persons does not increase the risk of uncontrolled blood pressure" and may even reduce the risk of death from any cause.
4. Habitual coffee consumption (from 3 to 5 cups/day), has neutral or even beneficial impact on blood pressure values and the new onset of hypertension.
The same intake significantly reduces the incidence of cardiovascular disease, as well as all-cause mortality.
5. The consumption of coffee is compatible with a correct and balanced lifestyle and should therefore not be discouraged in subjects with hypertension and cardiovascular diseases.
doi.org/10.1080/080370…
6. Coffee drinking reduces systolic BP (SBP)
The most recent study (published this month) showed that drinking 2 cups of coffee per day reduced SBP by 5.2 mmHg and 3 cups of coffee per day reduced SBP by 9.7 mmHg, as compared to non-coffee drinkers.
doi.org/10.3390/nu1502…
7. Habitual coffee and caffeinated beverages consumption is inversely associated with arterial stiffness and central and peripheral blood pressure.
doi.org/10.1080/096374…
8. Coffee does not increase the risk of hypertension in postmenopausal women.
In another study, caffeinated coffee, decaffeinated coffee, and caffeine were not found to be risk factors for hypertension in postmenopausal women
doi.org/10.3945/ajcn.1…
9. A single cup of caffeinated drink does not result in increase in BP.
In a randomized controlled trial, systolic and diastolic BP were similar, one hour after drinking a cup of either caffeinated or decaffeinated drink.
pubmed.ncbi.nlm.nih.gov/27051992/
10. Take home message
Habitual coffee consumption (1-3 cups/day)
*does not increase the risk of hypertension,
*does not increase BP in people who are already hypertensive,
One cup of coffee does not lead to acute increase in BP.
So, dear coffee lovers- have coffee and rejoice!

A young woman who would repeatedly experience the smell of burning incense (when in reality none burnt)
1. It was nearing the end of a busy OPD, when 27-year-old Radha was brought for consultation, accompanied by her husband and mother-in-law. They all looked anxious.
#MedTwitter
2. Radha married Raj a year ago. All went well until three months after marriage and the family was very happy.
One day at 11 PM, Radha started complaining that someone is burning incense at home, when all were actually sleeping. They considered it a dream & asked her to sleep.
3. These episodes increased in frequency and occurred 3-4 times every week. She would complain of burning incense smell at different times of day or night, and these symptoms would last only a few minutes.
Her family thought it's a God's message to her to pray with more devotion

HbA1c screening in adults can significantly reduce the time to diabetes diagnosis

1. HbA1C (glycosylated hemoglobin) is a marker of average plasma glucose during the previous 8-12 weeks.
An HbA1c of 6.5% is recommended as the cut point for diagnosing #diabetes.
#MedTwitter
2. In a recent population-based study in UK, HbA1c screening in adults aged 40–70 years reduced the time to diabetes diagnosis by a median of 2.2 years compared with routine clinical care. link.springer.com/article/10.100…

Sudden Cardiac Arrest (SCA) during Sports Activity in Older adults

1. We occasionally hear about apparently healthy people collapsing and dying while running, cycling or working out at gym.
A recent study looked at the prevalence of sports-related SCA in people aged >65 years.
2. Salient findings of the study and their implications
#gym #running #fitness #sports #cardiacarrest
#MedTwitter #CardioTwitter
3. Of 4,078 SCAs among people ≥65 years of age, 77 were Sports-related SCA (1.9%; 91% men).
The annual Sport-related SCA incidence among ≥65 years was 3.3/100,000 in Portland and 2.1/100,000 in Ventura. The most common associated activities were cycling, gym, and running.

Daily coffee consumption is good for chronic liver disease patients

1. Coffee is a popular beverage & is known to have multiple health-related benefits including better overall survival in several diseases. A systematic review looked at association of coffee and #liver disease.
2. Coffee consumption was associated with improved serum gamma glutamyl transferase (GGT), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) values in a dose dependent manner in individuals at risk for liver disease.
#MedTwitter
3. In chronic liver disease patients who consume coffee, a decreased risk of progression to cirrhosis, a lowered death rate in cirrhosis patients, and a lowered rate of hepatocellular carcinoma (liver cancer) development were observed.

The darker side of dark chocolates

1. Dark chocolates are popular due to their potential health benefits (they are rich in anti-oxidants and are good for heart) and moreover, they are low in sugar content. >50% consider them as safer and healthier option (as compared to candies)
2. But there’s a dark side to this “healthier” #chocolate. Research has found that some dark chocolate bars contain cadmium and lead—two heavy metals linked to a host of health problems.
Consumer report scientists detected cadmium & lead in many dark chocolate samples tested.
3. Consistent, long-term exposure to even small amounts of heavy metals can lead to a variety of #Health problems. The danger is greatest for #pregnantwomen and young #Children because the metals can cause developmental problems, affect #brain development, and lead to lower IQ.

1. Replacing just 9 minutes (per day) of sedentary behavior (SB) by moderate-vigorous #PhysicalActivity (MVPA) results in better #cognition scores over long-term in middle aged people.
MVPA time was derived using a step cadence of ≥100
#exercise #dementia
dx.doi.org/10.1136/jech-2…
2. Possible physiological explanations underlying a direct role for MVPA in supporting cognition include *Acute increases in cerebral perfusion,
*Growth factor release such as brain-derived neurotrophic factor,
*Hippocampal neurogenesis.
3. Lastly, MVPA, when attained by structured exercise, involves some degree of self-motivation, planning and social interaction, which are all factors considered to be cognitively stimulating.
