New York: Many of us feel lonely at certain times but loneliness and social isolation for a longer period of time may lead to increased risk of stroke or heart disease, find researchers.

The findings showed that loneliness and social isolation was associated with a 29 percent increased risk of a heart or angina attack and a 32 percent heightened risk of having a stroke.


“It suggests that addressing loneliness and social isolation may have an important role in the prevention of two of the leading causes of morbidity in high-income countries,” said researchers from York, Liverpool and Newcastle universities.

The study, involving more than 1,81,000 adults, included 4,628 coronary heart disease “events” — heart attacks, angina and death — and 3,002 strokes recorded during monitoring periods ranging from three to 21 years.

The results back public health concerns about the importance of social contacts for health and well-being.

“But one of the greatest challenges will be how to design effective interventions to boost social connections, taking account of technology,” the authors pointed out in a paper published online in the journal Heart.

“Further attention to social connections is needed in research and public health surveillance, prevention and intervention efforts,” they noted. (Bollywood Country Report)

When you're pregnant, the immune system is seeing the placenta for the first time in decades.

The US researchers have discovered a class of immune cells that plays a role in miscarriage, which affects about a quarter of pregnancies.

Researchers at the University of California-San Francisco found that the recently discovered subset of cells known as extrathymic Aire-expressing cells in the immune system may prevent the mother's immune system from attacking the placenta and fetus.

The researchers showed that pregnant mice who did not have this subset of cells were twice as likely to miscarry, and in many of these pregnancies fetal growth was severely restricted.

"When you're pregnant, the immune system is seeing the placenta for the first time in decades -- not since the mother made a placenta when she herself was a fetus," said Eva Gillis-Buck, from UCSF.

"Our research suggests that this subset of immune cells is carrying out a sort of 'secondary education' -- sometimes many years after the better-known population of the educator cells have carried out the primary education in the thymus -- teaching T cells not to attack the fetus, the placenta and other tissues involved in pregnancy," she added. The findings are published in the journal Science Immunology.

It's not surprising that over half of those surveyed feel more comfortable using emojis than talking on the phone or in person.

The tiny emojis being shared on billions of devices worldwide can play a major role in digital communication, with most people saying that emoji compels them to feel more empathy towards others, according to an Adobe report.

Adobe's global emoji study found that emoji even helps people overcome language barriers and form connections that would otherwise be difficult to do.

"We were surprised and delighted by the discoveries made in the survey, most notably how enthusiastic respondents were for emoji as a means to express themselves," the company said in a statement.

Emojis sometimes get criticized for being overly saccharine, but this sweetness is key when it comes to diffusing some of the heaviness of online communication.

"Many of the emoji are focused on positive emotions, so it's easy to insert them into our conversations and lighten the mood," the Adobe study said.
