Some immunity to novel H1N1 flu found in seniors

Posted On Nov 18 2020 by

first_imgMay 21, 2009 (CIDRAP News) – In a search for factors that may give some patients a protective edge against novel H1N1 influenza, researchers said today that adults, especially those older than 60, appear to have some cross-antibody response but that seasonal influenza vaccines appear unlikely to offer any protection.The findings, from scientists at the US Centers for Disease Control and Prevention (CDC) appear in tomorrow’s edition of Morbidity and Mortality Weekly Report (MMWR). Results are based on microneutralization and hemagglutination inhibition assays on child and adult serum specimens that were used in previous vaccine studies by the CDC as well as its academic and industry partners.Epidemiologic patterns in the novel flu outbreak have consistently shown the disease taking its hardest toll on younger people—in the United States, 64% of the novel flu cases have occurred in the 5- to 24-year-old age-group. Officials have wondered if older people haven’t yet been exposed to the strain in the community or if another factor, such as preexisting immunity, is providing some protection against the virus. Only 1% of cases have occurred in people over age 65.Researchers assessed cross-reactive antibody levels to the novel influenza H1N1 virus in cohorts of children and adults before and after they had been vaccinated with a seasonal flu vaccine during any of the past four seasons.Before vaccination, children showed no cross-reactive antibody reaction to the new flu strain. However, the antibody was detected in 6% to 9% of adults ages 18 to 64 and in 33% of those older than age 60.Vaccination with any form of the seasonal flu vaccine did not provoke a response to the novel strain in children. Adults ages 18 to 64 who had been vaccinated showed a slight response to the new strain: a twofold increase compared with 12-fold to 19-fold increases seen against the seasonal H1N1 strain. No increase in cross-reactive antibody response was seen in people over age 60 who had been vaccinated.”These data suggest that receipt of recent (2005-2009) seasonal influenza vaccines is unlikely to elicit a protective antibody response to the novel influenza A (H1N1) virus,” the CDC reported.Though the number of sera samples from children was small, the findings suggest that US children are serologically naive to the new virus, the researchers concluded. However, the analysis suggests adults—especially those older than 60—have some degree of preexisting immunity to the novel strain.Anne Schuchat, MD, interim deputy director for the CDC’s science and public health program, today at a media briefing urged caution in interpreting the results. Cross-reactive antibody assessment is an indirect measure of immune response, and though the findings are interesting, they’re not definitive, she said. “The laboratory findings we’re reporting seem to correlate with the epidemiologic data that we have so far.”Another reason to not over-interpret the results, she said, is that the microneutralization assay was used as a surrogate and isn’t the standard test the CDC uses against influenza viruses. (Microneutralization assays appear more sensitive, but researchers have not agreed on clinical correlates for the method.) She also said the study findings are based on relatively small numbers of patient serum samples.The response in older people could be explained by exposure to a related virus, exposure to a seasonal flu vaccine that provided protection, or that immune response to the new virus might be similar to that of other viruses, Schuchat said. However, she added that CDC virologists have compared the novel strain with past viruses and found that the new one is very different. “It’s not a close genetic match,” she said.She also said experts aren’t very impressed by the prevaccination-to-postvaccination ratio of 2:1 that suggests a weak response to the new virus. “That’s pretty wimpy,” Schuchat said, adding that the ratio for seasonal flu vaccines ranges around 12:1. “Wouldn’t it be great if there was boosting? But we don’t think we have sufficient evidence of that at this point,” she said.CDC.

Messi to start Venezuela friendly on Argentina return

Posted On Jan 6 2020 by

first_img“It’s a joy for me and for everyone that he’s back,” Scaloni told a news conference on Thursday.“Now what remains is try and get the team to play along with him and get the best out of him. We’re all very happy that he’s back.”“It is the others who have to take that step so that Argentina can return to the level it had,” added Scaloni, who replaced Jorge Sampaoli as coach following the last-16 defeat by France at the 2018 World Cup.Messi has missed six friendlies since the tournament in Russia but many believe he will be an essential part of the team that travels to Brazil for the Copa America, which kicks off June 14.“We have a way of playing and feeling football in these six games we’ve had. We’re not going to change it, that (Messi) is coming is more incentive for us and another addition.”“We’ve played different systems and we’re going to do it in the same way, added to his great quality,” Scaloni added.“But we need the rest, who are all top players and key figures at their clubs, to give us that bit extra to try and be a great team.”Scaloni refused to be drawn on whether Messi would also travel with the squad for next week’s friendly against Morocco in Tangier, but said he would not risk the Barcelona forward’s fitness.The news that Messi would be involved for the game at Atletico Madrid’s Wanda Metropolitano ground pleased Venezuela coach Rafael Dudamel.“The presence of the best player in the world lifts the game’s expectation,” Dudamel said.“For us to take on Argentina is a good way to see how we stack up. The return of Lionel Messi makes the demands on us extremely high.”0Shares0000(Visited 1 times, 1 visits today) 0Shares0000Lionel Messi hasn’t played for Argentina since last year’s World Cup © AFP / BENJAMIN CREMELMADRID, Spain, Mar 22 – Lionel Messi will start Friday’s friendly against Venezuela in Madrid as he makes his return for Argentina following a self-imposed eight-month exile, coach Lionel Scaloni confirmed.Scaloni said that Messi would line up alongside Inter Milan forward Lautaro Martinez and Atlanta United’s Gonzalo Martinez in attack as he revealed his full starting team.last_img read more

Four new elements complete the seventh row of the periodic table

By studying how the massive nuclei of the new elements decay, researchers gained insight into the forces that hold atoms together. According to their findings, elements heavier than any yet createdmight have conformations that are especially stable—suggesting that if we can ever make atoms that big, they might stick around for longer than a few microseconds.

The newcomers are some of the heaviest ever discovered, with atomic numbers of 113, 115, 117, and 118. They will be named by the researchers who identified them, the final step before the elements take up their rightful places in the seventh row of the periodic table.Chemists classify elements by the number of protons per atom, which they call atomic number. Elements with more than 92 protons are unstable and not normally found in nature, but researchers have worked for decades to synthesize them and prove their brief existence. The International Union of Pure and Applied Chemistry (IUPAC) assesses the evidence for each new element, deciding when it’s strong enough to warrant official recognition and who should get credit for the discovery. Researchers first claimed to have created the heaviest known element, No. 118, in 1999, but the data in that study turned out to be fabricated. The real discoveries of the four new elements came between 2002 and 2010, thanks to a series of experiments with particle accelerators. The particle accelerators fired beams of lighter nuclei at samples of heavy elements, smashing the atoms together until some of them fused. IUPAC credited a team of Russian and U.S. scientists with the discovery of elements 115, 117, and 118. Element 113 will become the first element to be named in Asia, with credit going to a group of Japanese researchers at the RIKEN Nishina Center for Accelerator-Based Science in Wako.center_img Sign up for our daily newsletter Get more great content like this delivered right to you!
