अगर आप हरे-भरे इलाकों में रहते हैं तो आपको हृदय का रोग विकसित होने की संभावनाएं कम होती हैं। एक नए अध्ययन में यह बात सामने आई है। ईएससी कांग्रेस 2021 में प्रस्तुत किए गए निष्कर्षों से संकेत मिलता है कि पूरे अध्ययन के दौरान उच्च हरे भरे वाले ब्लॉकों के निवासियों में कम हरे भरे वाले ब्लॉकों की तुलना में किसी भी नई कार्डियोवैस्कुलर स्थितियों को विकसित करने की 16 प्रतिशत कम संभावनाएं थीं।
यूनिवर्सिटी ऑफ मियामी, अमेरिका के विलियम ऐटकेन ने कहा, "जब कोई क्षेत्र उच्च हरापन बनाए रखता है और जब हरापन बढ़ता है, तो समय के साथ हरेपन के उच्च स्तर हृदय की स्थिति और स्ट्रोक की कम दरों से जुड़े होते हैं।"
एटकेन ने कहा, "यह उल्लेखनीय था कि ये संबंध केवल पांच वर्षों में दिखाई दिए, पॉजिटिव पर्यावरणीय प्रभाव के लिए अपेक्षाकृत कम समय में।"
अध्ययन के लिए, टीम में 65 वर्ष और उससे अधिक आयु के 2,43,558 यूएस मेडिकेयर लाभार्थी शामिल थे जो 2011 से 2016 तक मियामी के एक ही क्षेत्र में रहते थे।
पांच साल के अध्ययन के दौरान दिल का दौरा, आलिंद फिब्रिलेशन, दिल की विफलता, इस्केमिक हृदय रोग, उच्च रक्तचाप और स्ट्रोक / क्षणिक इस्केमिक हमले सहित नई हृदय स्थितियों की घटनाओं को प्राप्त करने के लिए मेडिकेयर रिकॉर्ड का उपयोग किया गया था।
पृथ्वी की सतह से परावर्तित दृश्य और निकट-अवरक्त (अदृश्य) सूर्य के प्रकाश की मात्रा का आकलन करने के लिए उपग्रह छवियों का उपयोग किया गया था। पौधों से क्लोरोफिल आमतौर पर ²श्य प्रकाश को अवशोषित करता है और निकट-अवरक्त प्रकाश को दर्शाता है, इसलिए दोनों को मापने से वनस्पति की मात्रा का संकेत मिलता है।
शहर के ब्लॉकों की हरियाली को तब निम्न, मध्यम या उच्च के रूप में वर्गीकृत किया गया था।
प्रतिभागियों को इस आधार पर वर्गीकृत किया गया था कि वे 2011 में निम्न, मध्यम या उच्च हरियाली वाले ब्लॉकों में रहते थे। 2016 में उन्हीं निवासियों और उनके ब्लॉक की हरियाली के लिए प्रक्रिया को दोहराया गया था।
टीम ने ब्लॉक-स्तरीय हरेपन के आधार पर किसी भी नए हृदय रोग के विकास की बाधाओं और नई हृदय स्थितियों की संख्या का विश्लेषण किया।
फॉलो-अप के दौरान कार्डियोवैस्कुलर स्थिति विकसित करने वाले प्रतिभागियों में, उच्च हरियाली वाले क्षेत्रों में कम हरेपन वाले ब्लॉकों की तुलना में 4 प्रतिशत कम नई बीमारियां विकसित हुईं। (एजेंसी)

San Francisco, Aug 19 (IANS) The independent Oversight Board on Thursday upheld Facebook's decision not to remove a post by a state-level medical council in Brazil saying Covid-19 lockdowns are ineffective.In March 2021, the Facebook page of a state-level medical council in Brazil posted a picture of a written notice on measures to reduce the spread of Covid-19, entitled "Public note against lockdown"."Facebook's decision to keep the content on the platform was consistent with its content policies," the board said in a statement.The notice claimed that lockdowns are ineffective, against fundamental rights in the Constitution and condemned by the World Health Organisation (WHO). It included an alleged quote from Dr David Nabarro, a WHO special envoy for Covid-19, stating that "the lockdown does not save lives and makes poor people much poorer".It claimed that the Brazilian state of Amazonas had an increase in deaths and hospital admissions after lockdown as evidence of the failure of lockdown restrictions. It added that lockdowns would lead to greater mental disorders, alcohol and drug abuse, and economic damage, amongst other things.The effective way to prevent against Covid include education campaigns about hygiene, masks, social distancing, vaccination and government monitoring -- but never lockdowns, the notice claimed.The page has over 10,000 followers. The content was viewed around 32,000 times and shared around 270 times. No users reported the content.While Facebook took no action against the content, it referred the case to the Board. The content continues to remain on the platform.According to the Board, the content contained inaccurate information which raises concerns considering the severity of the pandemic in Brazil.Since the content did not create a risk of imminent harm, it can stay on the platform, it noted.But, the Board questioned Facebook's "approach and made recommendations on health misinformation".On its part, Facebook informed the Board that it does not consider local context when assessing imminent physical harm. Facebook's fact-checking partners also did not assess the content although the post was eligible for review."Facebook should consider local context: Brazil is among the countries that are most affected by the pandemic, with anti-Covid measures in the country being politicised. The content was also shared by a public institution with a duty to provide reliable information," the Board said.The Board recommended Facebook to prioritise the fact-checking of content flagged as health misinformation which has been shared by public authorities, taking into account local context.Measures like warning labels to show the content is disputed can be used other than removal to counter the spread of Covid-19 misinformation, the Board noted.--IANSrvt/vd
London, Aug 18 (IANS) Britain reported another 170 coronavirus-related deaths, the highest number of fatalities recorded in one day since March 12, according to official figures released Tuesday.The total number of coronavirus-related deaths in Britain now stands at 131,149. These figures only include the deaths of people who died within 28 days of their first positive test, Xinhua news agency reported.Another 26,852 people in Britain have tested positive for Covid-19, bringing the total number of coronavirus cases in the country to 6,322,241.The latest data came as Britain's Medicines and Healthcare products Regulatory Agency (MHRA) approved the use of the Moderna Covid-19 vaccine for the 12 to 17-year-olds."I am pleased to confirm that the Covid-19 vaccine made by Moderna has now been authorized in 12-17 year olds. The vaccine is safe and effective in this age group," said June Raine, MHRA Chief Executive in a statement."It is for the Joint Committee on Vaccination and Immunization (JCVI) to advise on whether this age group should be vaccinated with the Covid-19 vaccine made by Moderna as part of the deployment program," said Raine.Nearly 90 per cent of the adults in Britain have received a Covid-19 vaccine, while more than 77 per cent have had the second jab, according to the latest figures.--IANSint/pgh

New Delhi, Aug 12 (IANS) Delhi Deputy Chief Minister Manish Sisodia on Thursday said that it is difficult to ascertain without a probe if there were any oxygen-related deaths during the second Covid wave. He said that he has written to the Union Health Ministry saying that it is difficult to find out the exact number of oxygen-related deaths without an investigation. He was addressing a virtual press conference here.Sisodia added, "It is wrong to say that no death happened due to oxygen shortage. We have written a letter to the Union Health Minister regarding this. It will be difficult to ascertain the number of deaths due to the oxygen crisis. But to say that oxygen has not caused any death will be a mockery of those who have lost their family members".Sisodia said the Delhi government had formed a committee to probe the deaths and prepare a report so that the affected families can be given a compensation of Rs 5 lakh each."But through the LG (Delhi's Lieutenant Governor), the Centre did not allow that committee to be formed. We are sending the file again to the Delhi LG for approval. We will carry out the probe with full responsibility and even punish those who were guilty," he added in the online media briefing.Sisodia said that the capital has recorded over 25,000 deaths due to the infection and his government will have to probe how many of these were linked to the oxygen crisis during April and May. "We cannot say that there was no oxygen crisis. The families of patients, hospitals were sending out SOS messages for help at that time," he said.Earlier, Sisodia had said that the Delhi government has not received any letter from the Centre inquiring if any deaths in the national capital occurred due to oxygen shortage during the second Covid wave.--IANSavr/bg
London, Aug 6 (IANS) A team of scientists have identified an experimental drug that may help prevent Covid-related heart damage.Scientists at the University of Cambridge grew heart cells in the lab using human embryonic stem cells, to understand how the virus infects the heart cells. Crucially, these model heart cells also contained the key components necessary for SARS-CoV-2 infection -- in particular, the ACE2 receptor.Using the model, they identified an experimental peptide drug called DX600 which can prevent the virus from entering the heart cells. The findings are published in the journal Communications Biology."Using stem cells, we've managed to create a model which, in many ways, behaves just like a heart does, beating in rhythm. This has allowed us to look at how the coronavirus infects cells and, importantly, helps us screen possible drugs that might prevent damage to the heart," said Dr Sanjay Sinha from the Wellcome-MRC Cambridge Stem Cell Institute.The team showed that some drugs that targeted the proteins involved in SARS-CoV-2 viral entry significantly reduced levels of infection. These included DX600 -- an ACE2 peptide antagonist which is a molecule that specifically targets ACE2 and inhibits the activity of peptides that play a role in allowing the virus to break into the cell.DX600 was around seven times more effective at preventing infection compared to the antibody, though the researchers say this may be because it was used in higher concentrations. The drug did not affect the number of heart cells, implying that it would be unlikely to be toxic."The spike protein is like a key that fits into the 'lock' on the surface of the cells -- the ACE2 receptor -- allowing it entry. DX600 acts like gum, jamming the lock's mechanism, making it much more difficult for the key to turn and unlock the cell door," said Professor Anthony Davenport from the Department of Medicine and a fellow at St Catharine's College, Cambridge.He added that further research is needed on this drug, "but it could provide us with a new treatment to help reduce harm to the heart in patients recently infected with the virus, particularly those who already have underlying heart conditions or who have not been vaccinated." It may also "help reduce the symptoms of long Covid".--IANSrvt/vd
