CNN —Nearly 62,000 people died heat-related deaths last year during Europe’s hottest summer on record, a new study has found — more heartbreaking evidence that heat is a silent killer, and its victims are vastly under-counted. Of the nearly 62,000 deaths analyzed, heat-related mortality rate was 63% higher in women than in men. “The acceleration of warming observed over the last 10 years underlines the urgent need to reassess and substantially strengthen prevention plans,” Achebak said. Heat deaths have outpaced hurricane deaths in the country by more than 8-to-1 over the past decade, according to data tracked by the National Weather Service. Yet the United States’ heat mortality numbers would suggest that far fewer people are dying from heat than in Europe.

He seems to have been protected by a rare gene change that enhanced the function of a protein that helps nerve cells communicate. Scientists say that understanding how this gene change defended his brain may help prevent Alzheimer’s in other people. “Another big insight from this case is, it seems like maybe you don’t need this everywhere in the brain,” Arboleda-Velasquez said. This is the pathway that is important for extreme protection against Alzheimer’s,’ ” Arboleda-Velasquez said. The sister of the man in the new study also shared the rare protective gene change, and it helped her, but not as much.

Some doctors are urging patients to cut back their consumption of sugar substitutes as questions mount about their health effects. In the latest study, published February in the journal Nature Medicine, Cleveland Clinic researchers found that the commonly used zero-calorie sweetener erythritol was associated with an increased risk of heart attacks, strokes and death within three years.

☆ Erythritol, an ingredient in stevia, linked to heart attack and stroke, study finds
▼ + stars: | 2023-02-27 | by ( Sandee Lamotte | ) edition.cnn.com time to read: +9 min

CNN —A sugar replacement called erythritol — used to add bulk or sweeten stevia, monkfruit and keto reduced-sugar products — has been linked to blood clotting, stroke, heart attack and death, according to a study. “If your blood level of erythritol was in the top 25% compared to the bottom 25%, there was about a two-fold higher risk for heart attack and stroke,” Hazen said. Clots can break off and travel to the heart, triggering a heart attack, or to the brain, triggering a stroke. “There appears to be a clotting risk from using erythritol,” Freeman said. In all three populations, researchers found that higher levels of erythritol were connected to a greater risk of heart attack, stroke or death within three years.

☆ Risk of a dangerous new Covid variant in China is ‘quite low,’ U.S. health expert says
▼ + stars: | 2022-12-30 | by ( Evelyn Cheng | Evelyn Cheng Is A Senior Correspondent With Cnbc. | ) www.nbcnews.com time to read: +3 min

Murray, director of the Institute for Health Metrics and Evaluation, pointed out there were likely billions of omicron infections worldwide this year, but no new Covid variant has emerged, only subvariants of omicron. “That’s why I would put the risk as quite low that there is a dangerous new variant in China,” he said. The U.S., Japan and a few other countries this week subsequently announced new Covid testing requirements for travelers from China. China’s National Health Commission said Sunday it would stop releasing daily information on Covid infections and deaths. Covid testing is no longer mandatory in China.

According to the group's projections, cases in China would peak around April 1, when deaths would reach 322,000. About a third of China's population will have been infected by then, IHME Director Christopher Murray said. China's national health authority has not reported any official COVID deaths since the lifting of COVID restrictions. Based on China's population of 1.41 billion, and without measures such as a mass vaccination booster campaign, that amounts to 964,400 deaths. China's National Health Commission said on Friday it was ramping up vaccinations and building stocks of ventilators and essential drugs.

☆ Just a couple minutes of vigorous activity several times a day might lower one's risk of death

"For years, everybody assumed that the health benefits of physical activity required at least 10 minutes," she said. Previous research from the University of Sydney has also found that vigorous physical activity is associated with lower rates of heart disease. A 2019 study also determined that stair climbing was associated with a lower risk of death among older men. Current U.S. guidelines say adults need 150 minutes of moderate physical activity per week, such as brisk walking, riding a bike or playing tennis. "There are just so many ways you can incorporate physical activity into a normal lifestyle," DiPietro said.

☆ Omicron boosters are weaker against BQ.1.1 subvariant that is rising in U.S., study finds
▼ + stars: | 2022-12-06 | by ( Spencer Kimball | ) www.cnbc.com time to read: +1 min

Covid shots designed to protect against the omicron variant trigger a weaker immune response against the rapidly emerging BQ.1.1 subvariant than the previously dominant strain, according to a new lab study. Scientists at the University of Texas Medical Branch, in a study published online Tuesday in Nature Medicine, found that the booster shots performed well against the BA.5 subvariant they were designed to target. People with a prior history of infection who received an omicron booster, however, had a stronger response to BQ.1.1. Omicron BQ.1.1 subvariant appears on track to become the dominant variant in the U.S. Omicron BA.5, on the other hand, now represents about 14% of new infections.

☆ As China moves away from zero-Covid, health experts warn of dark days ahead

Across the country, however, some parts of residential communities and buildings designated high risk by authorities are still locked down. A QR code for Covid-19 contact tracing displayed at the entrance to a subway station in Shanghai, China, on Monday. Top health officials on November 28 announced a new plan to bolster elderly vaccination rates, but such measures will take time, as will other preparations for a surge. Minimizing the worst outcomes in a transition out of zero-Covid depends on that preparation, according to Cowling. From that perspective, he said, “it doesn’t look like it would be a good time to relax the policies.”

☆ Factbox: How many people might die, and why, if China loosens COVID restrictions

REUTERS/Thomas PeterSHANGHAI, Dec 3 (Reuters) - China has started taking steps to ease its zero-COVID policy, fuelling a mix of relief and worry as the public waits to see the health consequences, and impact on the medical system, of a full-blown exit. Researchers have analysed how many deaths the country could see if it pivots to a full reopening, with most pointing to the country's relatively low vaccination rates and lack of herd immunity as some of its most vulnerable spots. As of Friday, China reported 5,233 COVID-related deaths and 331,952 cases with symptoms. They forecasted that peak demand on intensive care would be more than 15 times capacity, causing roughly 1.5 million deaths, based on worldwide data gathered about the variant's severity. The company said it modelled its data on Hong Kong's BA.1 wave in February, which occurred after the city eased restrictions after two years.

☆ 2 women stopped binge eating after an implant started zapping their brains with electricity, a small study found
▼ + stars: | 2022-11-14 | by ( Marianne Guenot | ) www.businessinsider.com time to read: +4 min

A brain implant reduced two patients' binge eating for at least six months. The two patients were fitted with a brain implant to zap the part of the brain linked to cravings. The idea of targeting brain waves to fight cravings has been appealing, so much so that Elon Musk recently said his Neuralink brain implant could one day fight morbid obesity. The implant used in the study learned to recognize those brainwaves and zap that region with electricity to scramble them, which seemed to cut the cravings short. With just two patients, the scientists can't prove for sure that it was the implant causing the weight loss.

☆ Repeat COVID is riskier than first infection, study finds
▼ + stars: | 2022-11-10 | by ( Nancy Lapid | ) www.reuters.com time to read: +3 min

"Reinfection with COVID-19 increases the risk of both acute outcomes and long COVID," said Dr. Ziyad Al-Aly of Washington University School of Medicine in St. Louis. "Even if one had prior infection and was vaccinated - meaning they had double immunity from prior infection plus vaccines - they are still susceptible to adverse outcomes upon reinfection," Al-Aly, the study leader, said. The higher risks were most pronounced in the first month after reinfection but were still evident six months later. The cumulative risks and burdens of repeat infection increased with the number of infections, even after accounting for differences in COVID-19 variants such as Delta, Omicron and BA.5, the researchers said. "We had started seeing a lot of patients coming to the clinic with an air of invincibility," Al-Aly told Reuters.

☆ COVID raises risk of long-term brain injury, large U.S. study finds

The year-long study, published in Nature Medicine, assessed brain health across 44 different disorders using medical records without patient identifiers from millions of U.S. veterans. Brain and other neurological disorders occurred in 7% more of those who had been infected with COVID compared with a similar group of veterans who had never been infected. That translates into roughly 6.6 million Americans who had brain impairments linked with their COVID infections, the team said. Compared with the control groups, people infected with COVID had a 77% higher risk of developing memory problems.

Британские ученые проанализировали данные о самочувствии двух с половиной миллионов шотландцев, которые получили первую дозу вакцин от коронавируса AstraZeneca или Pfizer/BioNTech, и признали наличие побочных эффектов у первого препарата. У некоторых пациентов, получивших вакцину AstraZeneca, наблюдались слабые нарушения свертываемости крови и связанные с этим кровотечения. При этом у препарата Pfizer подобных побочных эффектов не было обнаружено. Специалисты установили, что частота побочных эффектов, которые связаны с нарушением свертываемости крови у привитых вакциной AstraZeneca, составляет 1,13 случая на 100 тысяч человек. При этом ученые под руководством Азиза Шейха (Aziz Sheikh) из Эдинбургского университета выяснили, что обе вакцины в целом переносятся хорошо.

У слепого человека, потерявшего зрение из-за нейродегенеративного заболевания глаз несколько десятилетий назад, зрение было частично восстановлено благодаря первой в своем роде экспериментальной генной терапии. Пациенту, 58-летнему мужчине, 40 лет назад был поставлен диагноз "пигментный ретинит" - прогрессирующая наследственная группа генетических заболеваний, приводящих к потере зрения из-за мутаций, которые вызывают повреждение светочувствительных фоторецепторных клеток сетчатки. Пигментный ретинит (ПР) обычно считается редким заболеванием: по оценкам, только один из 4000 человек страдает этим заболеванием, но, тем не менее, считается, что им страдают около 2 миллионов человек во всем мире. У рассматриваемого 58-летнего пациента ухудшение зрения из-за RP означало, что его острота зрения была ограничена восприятием света. Он все еще мог воспринимать присутствие света и отличать его от темноты, но не мог различить ничего другого.

Cel puţin unul din trei bolnavi de COVID-19 spitalizaţi îşi vede sănătatea afectată pe termen lung, cu diferite organe afectate şi inclusiv probleme de ordin psihologic, potrivit unui nou studiu realizat în Europa, SUA şi China. Cele mai frecvente sunt oboseala intensă (53,1%), respiraţia dificilă (43,4%), durerile articulare (27,3%) sau durerile toracice (21,7%). Rezultatele privind sănătatea psihică sunt de asemenea preocupante. Astfel, din 402 pacienţi italieni, la o lună după externare 56% au fost diagnosticaţi cel puţin cu o afecţiune psihică, respectiv stres post-traumatic pentru 30% dintre ei, apoi depresie, anxietate etc. În concluzie, autorii articolului subliniază că prevenirea deceselor cauzate de COVID-19 nu este de ajuns sub aspectul acţiunii medicale şi este nevoie să se aprofundeze efectele acestei boli pe termen lung.

В семье с заболевшими родителями дети смогли остановить SARS-CoV-2 и выработать антитела. Медики были настолько ошеломлены результатом, что повторяли тест и перепроверяли в разных лабораториях, но факт был налицо - не заболев, дети выработали антитела к атаке вируса. Мельбурнская Королевская детская больница и Детский исследовательский институт Мердока попросили семью Магуайр принять участие в исследовании. С помощью маленьких Ленни, Бодхи и Марли медикам удалось узнать много нового и важного для понимания иммунного ответа у детей на COVID-19. Результаты исследования опубликованы в журнале Nature Medicine, они станут началом более широких исследований того, чем и как именно защищены дети от симптоматической инфекции.

Американские ученые нашли способ выявить COVID-19 с помощью фитнес-браслета. Специалисты изучили данные тех, кто сообщил о появлении симптомов и прошел тестирование на новый коронавирус. Знание результатов теста позволило им определить конкретные изменения в состоянии организма, с большей вероятностью указывающие на COVID-19 по сравнению с другими заболеваниями. Отмечается, что показатели фитнес-браслетов помогли выявить отклонения от индивидуальных норм, выражающиеся в уровне активности или частоты пульса в состоянии покоя, а также изменения диапазона сна. Как указывают ученые, учет данных показателей вместе с жалобами пациентов помог значительно упростить выявление зараженных COVID-19 по сравнению с моделью, учитывавшей исключительно симптоматику, а также определить заболевание в бессимптомной форме и на ранней стадии.

Mulţi oameni care se recuperează în urma infecţiei cu COVID-19 dezvoltă agenţi imuni în sânge numiţi anticorpi care sunt specifici noului coronavirus. Aceşti anticorpi sunt folositori pentru că indică cine a fost infectat, indiferent dacă persoana în cauză a prezentat sau nu simptome. Un studiu anterior publicat în Nature Medicine a sugerat că anticorpii pot dispărea după două luni pentru unii oameni care au avut virusul dar nu au prezentat simptome.
