Reply to Researchers looked at health outcomes for a population of more than 400,000 middle-aged and older adults, and found that both social isolation and loneliness increased the risk of hospitalization or death from heart failure by 15% to 20%. by Wagamaga

Studies have shown that social isolation and loneliness are important risk factors for cardiovascular disease, but less has been known about their specific connection with heart failure. A new study published in JACC: Heart Failure shows that both social isolation and loneliness are associated with higher rates of heart failure but whether or not a person feels lonely is more important in determining risk than if they are actually alone. Social disconnection can be classified into two different, but connected, components. “Social isolation” refers to being objectively alone or having infrequent social connections, while “loneliness” is defined as a painful feeling caused when someone’s actual level of social interaction is less than they would like it to be.

For the study, researchers looked at data from the UK Biobank study, which followed population health outcomes over 12 years and assessed psychosocial factors like social isolation and loneliness through self-reported questionnaires. Researchers looked at health outcomes for a population of more than 400,000 middle-aged and older adults. Previous studies have been inconclusive, with inconsistent results and have used different measurements for assessing social isolation and loneliness, said Jihui Zhang, MD, PhD, a researcher at Guangzhou Medical University in Guangzhou, China, and senior author of the study.

The researchers found that both social isolation and loneliness increased the risk of hospitalization or death from heart failure by 15% to 20%. However, they also found that social isolation was only a risk factor when loneliness was not also present. In other words, if a person was both socially isolated and felt lonely, loneliness was more important. Loneliness also increased risk even if the person was not socially isolated. Loneliness and social isolation were more common in men and were also associated with adverse health behaviors and status, such as tobacco use and obesity.

Reply to comment by Bunktavious in New evidence suggests that ‘hybrid’ immunity, the result of both vaccination and a bout of COVID-19, can provide partial protection against reinfection for at least eight months. Immunity acquired by booster vaccination alone seems to fade somewhat faster. by MistWeaver80

It takes around 70,000 MRNA vaccinations to be administered prevent one hospitalisation. They probably survived.

Reply to Newly-discovered Earth-mass exoplanet — named Wolf 1069 b — may provide durable habitable conditions across a wide area of its dayside by marketrent

Findings in title quoted from the linked summary^1 for a hyperlinked journal paper.^2

From the linked summary^1 released by the Max Planck Institute for Astronomy:

>A team of astronomers led by MPIA scientist Diana Kossakowski have discovered an Earth-mass exoplanet orbiting in the habitable zone of the red dwarf star Wolf 1069.

>Although the rotation of this planet, named Wolf 1069 b, is probably tidally locked to its path around the parent star, the team is optimistic it may provide durable habitable conditions across a wide area of its dayside.

>The absence of any apparent stellar activity or intense UV radiation increases the chances that Wolf 1069 b could have retained much of its atmosphere.

>With a distance of 31 light-years, Wolf 1069 b is the sixth closest Earth-mass planet in the habitable zone of its host star.

>Because of its favourable prospects regarding habitability, it is among a small illustrious group of targets, such as Proxima Centauri b and TRAPPIST-1 e, to search for biosignatures.
