Home Health Health on January 18, 2022 With omicron having rapidly driven up COVID infections, attention is once again focusing on antibodies, and reasonably so. They play a critical role in fighting off viruses and are important for preventing the coronavirus from infecting our cells. This is why some countries have mounted booster campaigns in response to recent COVID surges - to top antibody levels up. But there's a problem. COVID antibodies don't persist that well - hence the desire for boosters. Indeed, while these extra jabs maintain good protection against severe COVID, it's estimated that people receiving a third dose of the Pfizer vaccine will see their protection against developing COVID symptoms (of any degree) drop from 75 per cent to 45 per cent over the ten weeks following their booster. Scientists have questioned whether topping up antibodies, only to see them soon fade away, is sustainable. If we want to … [Read more...] about COVID-19: Why T Cell Vaccines Could Be The Key To Long-Term Immunity

Home Health Wellness Wellness on January 18, 2022 An Israeli hospital said on January 17 that preliminary research indicates a fourth dose of the coronavirus vaccine provides only limited defense against the Omicron variant that is raging around the world. Sheba Hospital last month began administering a fourth vaccine to more than 270 medical workers — 154 who received a Pfizer-BioNtech vaccine and 120 others who received Moderna's. All had previously been vaccinated three times with the Pfizer-BioNtech vaccine. The clinical trial found that both groups showed an increase in antibodies “slightly higher” than following the third vaccine last year. But it said the increased antibodies did not prevent the spread of Omicron. “Despite increased antibody levels, the fourth vaccine only offers a partial defence against the virus,” said Dr Gili Regev-Yochay, director of the hospital's infection disease unit. “The vaccines, which were … [Read more...] about COVID Vaccine 4th Dose Shows Limited Results With Omicron, Says Study In Israel
Home Health Health on January 19, 2022 Giving a clarion call to world leaders to make 2022 a "true moment of recovery", UN Secretary-General Antonio Guterres on Monday said that the Covid-19 pandemic has to be confronted with equity and fairness, cautioning that failure to vaccinate every person will give rise to new variants that will bring daily life and economies to a grinding halt. Guterres, in his virtual remarks to the opening of the 2022 World Economic Forum (WEF), said: "The last two years have demonstrated a simple but brutal truth - if we leave anyone behind, we leave everyone behind". He gave a clarion call to "stand together to make 2022 a true moment of recovery." Noting that the global event is taking place in the shadow of an "enormously difficult" period for economies, people and the planet, Guterres urged the international community, especially the global businesses, that "we need all hands on deck" for … [Read more...] about Failure To Vaccinate Everyone Will Give Rise To New Variants: UN Chief
Home Health Health on January 18, 2022 Hydroxychloroquine, the anti-malaria drug controversially touted as a cure for COVID despite a lack of robust evidence, is creating renewed interest as a potential treatment for omicron. The discussion has been sparked by a new study from the University of Glasgow, which is yet to be published in a scientific journal, that looks at how antibodies from vaccines block omicron from entering cells. The researchers conclude, as many others have, that antibodies (the proteins that neutralise the virus) against previous variants or induced by vaccines are less effective against omicron. What's interesting, though, is that the study finds that omicron may have changed the way it enters cells. SARS-CoV-2, the virus that causes COVID, is coated in a lipid bilayer (a thin membrane made of two layers) just like our cells. When the virus enters our cells, the bilayers fuse like oil droplets on the … [Read more...] about Omicron: Is Anti-Malaria Drug Hydroxychloroquine Really Effective Against The COVID Variant?
Home Health Health on January 19, 2022 Asymptomatic animal handlers at a private zoo in South Africa transmitted the Delta variant of COVID-19 to captive lions, who were placed in quarantine and developed symptoms like breathing problems, runny nose and dry cough, according to a recent study by a team of scientists from the University of Pretoria. The research report, published recently in the journal 'Viruses’, also urged members of the public to be aware of the possibility of infecting their pet cats and dogs if they have COVID-19. The team was led by Professor Marietjie Venter, Head of the Zoonotic, Arbo-and Respiratory Virus Programme at the university's Department of Medical Virology; and Professor Katja Koeppel, Associate Professor of Wildlife Health at the Faculty of Veterinary Science. They conducted a study on three sick lions at the zoo during South Africa’s third wave of the COVID-19 pandemic late in 2021. “The team of … [Read more...] about Asymptomatic Animal Handlers Transmit COVID Delta Variant To Lions At Zoo In South Africa: Study
Home Health Health on January 19, 2022 There is no evidence of injectable steroids benefitting Covid patients not requiring oxygen supplementation or in continuation after discharge, according to the revised 'Clinical Guidance for Management of Adult COVID-19 Patients'. The revised guidelines issued by AIIMS, ICMR-COVID-19 National Task Force and Joint Monitoring Group (DGHS) under the Union health ministry also stated that anti-inflammatory or immunomodulatory therapy, such as steroids, can have the risk of secondary infection like invasive mucormycosis, when used too early, at a higher dose or for longer than required. Injection methylprednisolone 0.5 to one mg/kg in two divided doses, or an equivalent dose of dexamethasone, can be given usually for a duration of five to 10 days in moderate cases, the guidelines stated. The same drug in two divided doses of one to two mg/kg can be given for the same duration in severe cases. … [Read more...] about COVID-19 Treatment: Govt Issues Revised Guidelines On Use Of Drugs, Therapies

Home Health Health on January 16, 2022 A 26-year-old BESCOM lineman, while working Devarabeesanahalli in Bengaluru was accidentally electrocuted and was brought to the Sakra World Hospital Emergency by his colleagues and the police on the morning of 2 December 2022. There was no heartbeat when he arrived at the emergency department. His heart was affected by an abnormal rhythm called Ventricular Fibrillation, where the electrical activity of the heart becomes erratic and uncontrolled, and the heart muscle fails to contract with its usual synchrony effectively stopping the heart. In victims of electrocution, this is could be one of the causes of instant death. When the heart stops the brain is starved of oxygen and there are only minutes left before it begins to undergo irreversible cell death. Survivors of cardiac arrests like this, often land in a vegetative state, especially if CPR was late and the brain was deprived of oxygen for too long. … [Read more...] about What Is Ventricular Fibrillation?

Home Pregnancy parenting Kids Kids on January 18, 2022 Lockdowns during the pandemic aimed to limit the spread of COVID-19 and related deaths. However, these lockdowns also affected how active people were. Children became significantly more sedentary. There is a risk that short term changes in children’s physical activity in reaction to COVID-19 may end up extending beyond the duration of the pandemic. It is very easy for habits to become established, and for a more sedentary and less physically active lifestyle to become normal and ingrained in young people. However, there are ways children can be encouraged to be more active. These include getting the whole family involved in physical activity and building exercise into a routine. Global Trend Research from around the world has examined the extent that COVID-19 restrictions have had on children and their levels of physical activity. Canadian researchers carried out an online … [Read more...] about Children Exercised Less During COVID Lockdown – 4 Tips To get Them Moving Again
