A stroke appears to create a sticky situation inside the blood vessels of the brain that can worsen damage days, even months later, scientists report.

They have found that after stroke, exosomes — nanosized biological suitcases packed with an assortment of cargo that cells swap, like proteins and fats — traveling in the blood get activated and sticky and start accumulating on the lining of blood vessels, according to a collaborative study by the Medical College of Georgia and the University of Oxford.

Like a catastrophic freeway pileup, platelets, also tiny cells that enable our blood to clot after an injury, start adhering to the now- sticky exosomes, causing a buildup that can effectively form another clot, further obstruct blood flow to the brain and cause additional destruction, they report in the journal Scientific Reports.

THE EXTERNAL PHENOMENA of aging are known to all of us. We can expect graying hair, bone loss, fatigue or memory difficulties.

But what actually happens to our brain as we get older, and what goes wrong when aging develops into a neurological disease like Alzheimer’s or Parkinson’s? This is a primary focus of neurological specialists around the world working to map the brain and unlock its many mysteries.

Previous animal studies have shown that molecular changes in the composition of lipids and proteins in brain cells affect brain function and may cause cognitive impairment. Magnetic resonance imaging, or MRI, scans allow us to look into the human brain in a non-invasive manner and learn about the changes that occur in it with age.

Drinking tea at least three times a week is linked with a longer and healthier life, according to a study published today in the European Journal of Preventive Cardiology, a journal of the European Society of Cardiology (ESC).

“Habitual tea consumption is associated with lower risks of cardiovascular disease and all-cause death,” said first author Dr. Xinyan Wang, Chinese Academy of Medical Sciences, Beijing, China. “The favourable health effects are the most robust for green tea and for long-term habitual tea drinkers.”

The analysis included 100,902 participants of the China-PAR project2 with no history of heart attack, stroke, or cancer. Participants were classified into two groups: habitual tea drinkers (three or more times a week) and never or non-habitual tea drinkers (less than three times a week) and followed-up for a median of 7.3 years.

Nearly a third of U.S. heart patients die at home, which is more than the number who die in the hospital, according to a new study.

Researchers examined data on more than 12 million heart disease patients who died between 2003 and 2017. They looked at whether the deaths occurred in a hospital, home, nursing or long-term care facility, inpatient hospice, or elsewhere (outpatient medical facility, emergency department, or dead-on-arrival at the hospital).

The number of heart disease deaths in the hospital fell from nearly 331,000 in 2003 to nearly 235,000 in 2017. Home deaths, meanwhile, rose from almost 193,000 to over 265,000, accounting for about 31% of heart disease deaths in 2017.

Conflict within families can be stressful and confusing, and it can lead to feelings of sadness. It also is incredibly common and in many cases, a necessary part of family dynamics. New research from the University of Missouri highlights how caregivers can better manage family conflict as they deal with the approaching death of a loved one.

Jacquelyn Benson, assistant professor of human development and family science, found that autonomy is a central tension in caregiving at the end of life. She suggests that several strategies, including communication, formal support and emotional self-care, can be used by caregivers to address family conflict.

“Conflict is stressful, we all know that,” Benson said. “However, it also is necessary and can lead to positive change. I hope these findings will inspire alternative ways to think about family conflict when it comes to end-of-life decision-making.”

A team of New Jersey stroke researchers has linked recovery of reading and language competence with cerebral blood flow in the left reading network. Their findings may contribute to new approaches to identifying and treating reading deficits after stroke. The open access article, “Cerebral perfusion of the left reading network predicts recovery of reading in subacute to chronic stroke”  was epublished on August 26, 2019 in Human Brain Mapping. The authors are Olga Boukrina, PhD, and A.M. Barrett, MD, of Kessler Foundation, and William Graves, PhD, of Rutgers, the State University of New Jersey.

Despite the fundamental role of reading ability in everyday living, little research has been conducted on patterns of reading recovery after stroke, or the development of interventions to improve reading outcomes. In this study of left-brain stroke, a team of New Jersey scientists examined patterns of cerebral perfusion bilaterally, including left and right networks of brain areas important for healthy reading, the area surrounding the stroke lesion, and the corresponding contralateral area.

People often pass pebble poop in small, hard, separate lumps. However, the stool can also appear as a solid piece that looks as though it consists of pebbles. Both types are a sign of constipation.

Constipation is a common problem that most people experience from time to time. Chronic constipation can be painful, and it may indicate an underlying health problem.

In this article, learn about the causes of pebble poop, as well as the possible treatments and home remedies.

People with gum disease (periodontitis) have a greater likelihood of high blood pressure (hypertension), according to a study published today in Cardiovascular Research, a journal of the European Society of Cardiology (ESC).

Senior author Professor Francesco D’Aiuto of UCL Eastman Dental Institute, UK, said: “We observed a linear association — the more severe periodontitis is, the higher the probability of hypertension. The findings suggest that patients with gum disease should be informed of their risk and given advice on lifestyle changes to prevent high blood pressure such as exercise and a healthy diet.”

High blood pressure affects 30-45% of adults and is the leading global cause of premature death, while periodontitis affects more than 50% of the world’s population. Hypertension is the main preventable cause of cardiovascular disease, and periodontitis has been linked with increased risk of heart attack and stroke.

Even though exercise is known to be healthy, many people find it difficult to maintain an exercise program for a longer time. This applies even more to people with a chronic illness such as Parkinson’s disease, where physical and mental limitations are additional obstacles. The Park-in-Shape study, funded by ZonMW (Netherlands Organization for Health Research & Development), tested an innovative solution for this challenge. The participants were divided into two groups. Both groups had a motivational app at their disposal, which offered the participants rewards for exercising. The control group only performed stretching exercises, while the active intervention group was instructed to exercise for 30-45 minutes on a stationary bicycle at home, at least three times a week.

The active group’s exercise bikes were also equipped with motivating games, making the program more entertaining and challenging for the participants. For example, the participants could race against their own previous performance — a “ghost rider” — or against a group of other cyclists. The system adjusted the difficulty of the game to the patient’s heartbeat, making the challenge just right. The challenges also became more difficult as the participants got fitter.

CHOOSING AN APPROPRIATE assisted living community is a challenging decision for residents and family members alike. To help, U.S. News is now publishing an extensive directory and data resource on nearly 9,000 assisted living communities, in collaboration with Caring.com.

The new Assisted Living directory offers comparison information on key factors including size, location and health services offered for the millions of Americans making this decision each year. Families can use the directory to match the right community to their loved one’s unique needs.

The directory provides comprehensive information about health services, activities and amenities offered at each residence. Reviews from residents and families add perspective for almost all licensed assisted living communities in the U.S. The tool is designed to let individuals easily conduct a customized search for a highly rated facility by location, resident rating, Alzheimer’s and memory care and size.
