Drinking 2 Cups Of Coffee A Day Doubles Heart Attack Risk Of People With Hypertension: Study


Drinking two or more cups of coffee a day could put people with severely high blood pressure more at risk of suffering a stroke or heart attack. 

The latest study findings showed regular intake of caffeinated coffee in volumes of two or more cups could double the risk of hypertensive patients dying from a heart attack, stroke and other cardiovascular diseases. 

Interestingly, the same results were not found among those who drank green tea or just one cup of coffee daily. 

According to the researchers behind the study published in the Journal of the American Heart Association Wednesday, their main goal was to examine the impacts of coffee and green tea consumption on cardiovascular disease (CVD) mortality among people with severe hypertension. 

“Our study aimed to determine whether the known protective effect of coffee also applies to individuals with different degrees of hypertension and also examined the effects of green tea in the same population,” senior study author Dr. Hiroyasu said in a news release.

For the study, the team examined data from 18,609 participants aged 40 to 79. The participants were asked to complete a lifestyle, diet and medical history questionnaire. They also had health examinations. 

“Heavy coffee consumption was associated with an increased risk of CVD mortality among people with severe hypertension, but not people without hypertension and with grade 1 hypertension. In contrast, green tea consumption was not associated with an increased risk of CVD mortality across all categories of blood pressure (BP),” the team wrote in their conclusion. 

Prior research suggested that people who had a heart attack but drank one cup of caffeinated coffee daily could lower their death risk. This was also believed to help prevent heart attacks and strokes in healthy adults. However, other studies showed that too much coffee could increase blood pressure and even cause heart palpitations and anxiety, according to the American Heart Association

Both coffee and tea contain caffeine but in varying levels. An 8-ounce cup of green or black tea contains 30 to 50 mg caffeine. On the other hand, the same volume of coffee contains 80 to 100 mg of caffeine, as per the Food and Drug Administration.

Iso, the director of the Institute for Global Health Policy Research at the National Center for Global Health and Medicine in Tokyo, pointed out that the study findings should encourage people with severe hypertension to avoid drinking excessive coffee.

Scientists Identify Protein To Help Treat Brain Hemorrhage

Published

Does COVID-19 Affect Brain Development Of Babies In The Womb?


Chances of disability among survivors of hemorrhage are high, especially when it comes to long-term neurological deficits. Now, doctors have weighed the potential of a protein to treat this condition.

The protein in focus is called cerebral dopamine neurotrophic factor (CDNF), which has a demonstrated history of reducing Endoplasmic Reticulum stress, and is being tested for restorative treatment to neurological conditions such as Parkinson’s disease. Researchers from the Brain Repair Laboratory, University of Helsinki, forged an international collaboration with their Taiwanese colleagues to find out whether the protein shows favorable outcomes in treating brain bleed.

The authors found a streak of hope in the research after administering CDNF in an animal model of a brain hemorrhage. The research showed the component speeds up hemorrhagic lesion resolution, reduces brain swelling, and improves brain functioning, according to the scientific study published in Cell Death and Disease.

“Surprisingly, we found that cerebral dopamine neurotrophic factor acts on immune cells in the bleeding brain, by increasing anti-inflammatory mediators and suppressing the production of the pro-inflammatory cytokines that are responsible for cell signaling. This is a significant step towards the treatment of injuries caused by a brain hemorrhage, for which we currently have no cure,” Professor Mikko Airavaara, from the University of Helsinki, said in a news release on the findings.

Dr. Vassileios Stratoulias from the Brain Repair laboratory said in simple terms, all CDNF does is encourage immune cells in the brain to consume and remove the waste and debris produced by the brain after an intracerebral hemorrhage, which facilitates brain recovery.

Brain bleeding occurs within the meninges, which is located inside the skull, but outside the actual brain tissue. Intracerebral hemorrhage, alternatively called hemorrhage, is a type of brain bleeding, which occurs anywhere between lobes, pons and cerebellum of the brain.

“It’s interesting to note that after a bleeding episode, the brain contains a lot of waste and debris. Cerebral dopamine neurotrophic factor encourages immune cells in the brain to consume and remove the waste and debris, which is essential for the brain’s recovery!” he said.

The administration of cerebral dopamine neurotrophic factor also helped mitigate cell stress in the area that surrounds the hematoma, a swelling resulting from blood clotting at the site of blood vessel damage.

Scientists Suggest Simple Supplement To Combat Key Protein That Drives Aging

Scientists Suggest Simple Supplement To Combat Key Protein That Drives Aging


People are always trying out different techniques and supplements to combat aging signs. A new study has now suggested that a simple supplement could potentially accelerate anti-aging in humans.

The study, published in the journal PLOS Biology, found loss of a protein called Menin could be responsible for the aging process, and a dietary supplement of D-serine could reverse it in mice.

The study focused on hypothalamic Menin. The hypothalamus is part of the brain that acts as a mediator of physiological aging. It does so by increasing neuroinflammatory signaling over time. Further, inflammation encourages multiple age-related processes, both in the brain and the periphery.

“We speculate that the decline of Menin expression in the hypothalamus with age may be one of the driving factors of aging, and Menin may be the key protein connecting the genetic, inflammatory, and metabolic factors of aging. D-serine is a potentially promising therapeutic for cognitive decline,” Lige Leng of Xiamen University, Xiamen, China, and study author, said, SciTechDaily reported.

For the study, researchers created conditional knockout mice, which have reduced Menin activity. Reduction of Menin in younger mice increased hypothalamic neuroinflammation as well as aging-related phenotypes, such as reductions in bone mass and skin thickness, cognitive decline, and modestly reduced lifespan, the study found.

Moreover, loss of Menin was also found to induce a decline in levels of the amino acid D-serine. A neurotransmitter, D-serine is found in soybeans, eggs, fish, and nuts, and is also available as a dietary supplement. According to researchers, the downslide in the production of the amino acid was due to the loss of activity of an enzyme involved in its synthesis (which was in turn regulated by Menin).

In the experiment, the study authors delivered the gene for Menin into the hypothalamus of elderly (20-month-old) mice. It was found 30 days later that the mice showed improved skin thickness, bone mass, learning, cognition, and balance, which was in tandem with an increase in D-serine within the hippocampus–a region of the brain critical for learning and memory.

Similar benefits on cognition, not including the peripheral signs of aging, could be observed by undergoing three weeks of dietary supplementation with D-serine, as per the outlet.

“Ventromedial hypothalamus (VMH) Menin signaling diminished in aged mice, which contributes to systemic aging phenotypes and cognitive deficits. The effects of Menin on aging are mediated by neuroinflammatory changes and metabolic pathway signaling, accompanied by serine deficiency in VMH, while restoration of Menin in VMH reversed aging-related phenotypes,” Leng explained.

While on the topic of anti-aging, a drug prescribed for the treatment of type 2 diabetes is being used off-label as an anti-aging medication. Metformin belongs to a class of drugs called biguanides. However, there are no proven studies to support these claims.

Healthy Pets And Hospitalized Humans May Transmit Drug-Resistant Microbes To Each Other, Study Shows

Published

LA Offers Free COVID-19 Testing For Pets Exposed To Virus


A new, revealing study has found healthy dogs and cats can transmit multidrug-resistant organisms to their hospitalized owners and vice versa.

The study is being presented at this year’s European Congress of Clinical Microbiology & Infectious Diseases in Copenhagen, Denmark.

Led by Dr. Carolin Hackmann from Charité University Hospital Berlin, Germany, the study enrolled more than 2,800 hospital patients and their pets to test their hypothesis.

“Our findings verify that the sharing of multidrug-resistant organisms between companion animals and their owners is possible,” said Dr. Hackmann, SciTechDaily reported. “However, we identified only a handful of cases suggesting that neither cat nor dog ownership is an important risk factor for multidrug-resistant organism colonization in hospital patients.”

Antimicrobial resistance refers to the increased resilience of infection-causing microbes to the drugs used to kill them. As per the outlet, antimicrobial-resistant infections were responsible for more than 1.3 million deaths, and were connected to 5 million deaths across the globe in 2019.

For the study, researchers focused on the most common superbugs found in hospital patients–methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci, 3rd generation cephalosporin-resistant Enterobacterales and carbapenem-resistant Enterobacterales.

Called multidrug-resistant organisms (MDROs), these bacteria are resistant to treatment with more than one antibiotic.

In the study, nasal and rectal swabs were collected from around 3000 patients hospitalized in Charité University Hospital, Berlin, as well as from any dogs and cats that lived in their households.

The presence of the type of bacteria was identified by genetic sequencing.

Following analysis, it was found 30% of hospital patients tested positive for MDROs, and 70% tested negative. Furthermore, among those who tested MDRO-positive, the rate of dog ownership and cat ownership was 11% and 9% respectively. The figure was 13% in MDRO-negatives.

Moreover, all pet owners were requested to collect and send throat and stool swab samples of their pets. And 300 pet owners sent back samples from 400 pets. It was found 15% of dogs and 5% of cats tested positive for at least one MDRO.

“Although the level of sharing between hospital patients and their pets in our study is very low, carriers can shed bacteria into their environment for months, and they can be a source of infection for other more vulnerable people in the hospital such as those with a weak immune system and the very young or old,” Dr. Hackmann concluded, according to The Guardian.

In other news, an animal shelter in Luzerne County, Pennsylvania, has temporarily shut down after dozens of dogs contracted canine influenza.

“A few of our dogs started to get diarrhea, but that’s pretty normal for dogs that are in a new stressful environment. When our longer-term dogs started to get diarrhea and started not wanting to eat, we realized they weren’t themselves, that’s when we knew something was wrong,” shelter volunteer Emma Ripka said.
