New Covid 19 Infections

एक अध्ययन के अनुसार, 69 फीसदी लोगों ने कोविड संक्रमण से पहले सिरदर्द की शिकायत की है, यह इस बीमारी का प्रमुख लक्षण बन गया है। किंग्स कॉलेज लंदन के शोधकर्ताओं ने जोई कोविड लक्षण अध्ययन ऐप के डेटा का विश्लेषण किया और स्थिति के पहले लक्षणों में से एक के रूप में सिरदर्द पाया। एक्सप्रेस डॉट को डॉट यूके की रिपोर्ट के अनुसार, यह बुखार, खांसी और हानि या स्वाद और गंध में बदलाव जैसे अन्य क्लासिक कोविड लक्षणों की तुलना में अधिक सामान्य है। अध्ययन में बताया गया है कि कुछ कोविड रोगियों को प्रारंभिक संक्रमण की तुलना में अधिक समय तक सिरदर्द के साथ देखा गया, यह संकेत भी लंबे कोविड के लिए एक विशेषता है। अध्ययन के अनुसार, हमारे डेटा से पता चलता है कि ये सिरदर्द अक्सर आते हैं और जाते हैं, लेकिन शुक्र है कि वे समय के साथ धीरे-धीरे कम हो जाते हैं। हालांकि यह दर्दनाक लक्षण बच्चों में कम आम लगता है, कोरोनोवायरस सिरदर्द सभी आयु समूहों में देखा जाता है। अध्ययन के अनुसार, इसलिए, हालांकि कोविड -19 वाले कई लोग सिरदर्द का अनुभव करते हैं। जरूरी नहीं है कि सिरदर्द वाले अधिकांश लोगों को कोविड -19 नहीं होगा। थकान और गंध की कमी के साथ सिरदर्द कोविड को संकेत दे सकता है। रिपोर्ट में कहा गया है कि अन्य लक्षण जो वायरस की दिशा को भी इंगित कर सकते हैं, उनमें गले में खराश, बुखार, मांसपेशियों में असामान्य दर्द और लगातार खांसी और चक्कर आना शामिल हैं। यह भी पढ़े► कोविड रोगियों ने माना स्वस्थ्य होने में योग ने की मदद

People infected with Covid-19 had a roughly 25 per cent increased risk of developing a psychiatric disorder in the four months following their infection, compared with those who had other types of respiratory tract infections, finds a study. Researchers at Oregon State University in the US found that Covid patients had a 3.8 per cent rate of developing a psychiatric disorder compared with 3.0 per cent for other respiratory tract infections. The 0.8 per cent difference amounts to about a 25 per cent increased relative risk. The team looked specifically at anxiety disorders and mood disorders and found a minor but significant increase in risk for anxiety disorders and no change in risk for mood disorders. The results speak to the need for both patients and health care providers to be more proactive when it comes to addressing mental health concerns following Covid infection, said Lauren Chan, doctoral student in nutrition in OSU's College of Public Health and Human Sciences. "For people that have had Covid, if you're feeling anxiety, if you're seeing some changes in how you're going through life from a psychiatric standpoint, it's totally appropriate for you to seek some help," Chan said. For the study, published in the journal World Psychiatry, researchers included data of 46,610 Covid-19 positive individuals and control patients who were diagnosed with a different respiratory tract infection so they could compare how Covid specifically affected patients' mental health. They looked at the rate of psychiatric diagnoses for two time periods: from 21 to 120 days after patients' Covid diagnosis, and from 120 to 365 days after diagnosis, limited to patients with no previous mental illness. When patients leave a doctor's office, sometimes care stops there, but Chan recommended that providers consider calling in two weeks for a check-in. "I don't want to say that every single person who gets Covid is going to have this type of problem, but if you start to have concern for yourself or a family member, it's not unheard of. You should definitely seek care for yourself or others around you," Chan said. Read More► Dogs Can Detect Covid-19 Faster Than Rapid Antigen Test: Study

London: Finding it hard to raise levels of Vitamin D, popularly known as the sunshine vitamin? Scientists have developed gene-edited tomatoes that could be a simple and sustainable innovation to address the global health problem. Researchers John Innes Centre in the UK used gene editing to turn off a specific molecule in the plant's genome which increased provitamin D3 in both the fruit and leaves of tomato plants. It was then converted to Vitamin D3 through exposure to Ultraviolet B light. Vitamin D is created in our bodies after skin's exposure to UVB light, but the major source is food. This new biofortified crop could help millions of people with Vitamin D insufficiency, a growing issue linked to higher risk of cancer, dementia, and many leading causes of mortality, according to the study, which appears in the journal Nature Plants. Tomatoes naturally contain one of the building blocks of Vitamin D3, called provitamin D3 or 7-dehydrocholesterol (7-DHC), in their leaves at very low levels. Provitamin D3, does not normally accumulate in ripe tomato fruits. Researchers used CRISPR-Cas9 gene editing to make revisions to the genetic code of tomato plants so that provitamin D3 accumulates in the tomato fruit. The leaves of the edited plants contained up to 600 microgram of provitamin D3 per gram of dry weight. The recommended daily intake of vitamin d is 10 micrograms for adults. When growing tomatoes leaves are usually waste material, but those of the edited plants could be used for the manufacture of vegan-friendly Vitamin D3 supplements, or for food fortification. "We've shown that you can biofortify tomatoes with provitamin D3 using gene editing, which means tomatoes could be developed as a plant-based, sustainable source of vitamin D3," said Professor Cathie Martin, corresponding author of the "Forty per cent of Europeans have vitamin D insufficiency and so do one billion people world-wide. We are not only addressing a huge health problem, but are helping producers, because tomato leaves which currently go to waste, could be used to make supplements from the gene-edited lines," Martin added. The study noted that the provitamin D enriched tomatoes could be much helpful for people adopting a plant-rich, vegetarian or vegan diet, and for the growing number of people worldwide suffering from the problem of vitamin D insufficiency.

London: People with diabetes were almost twice as likely to die with Covid and almost three times as likely to be critically or severely ill compared to those without diabetes, finds a study. The study conducted by researchers from the University of Aberdeen, UK found patients with diabetes had a significantly higher risk of requiring an intensive care admission and supplementary oxygen or being admitted in a critical condition in comparison to patients without diabetes. However, good control of blood sugar in these patients can significantly reduce this risk. "We found that following a Covid-19 infection, the risk of death for patients with diabetes was significantly increased in comparison to patients without diabetes," said Stavroula Kastora from the varsity. "We also show that good glycaemic control may be a protective factor in view of Covid-19 related deaths," she added, in the paper published in the journal Endocrinology, Diabetes and Metabolism. The team reviewed findings from 158 studies that included more than 270,000 participants from all over the world to determine how Covid affects people living with diabetes. The pooled results showed that people with diabetes were 1.87 times more likely to die with Covid, 1.59 times more likely to be admitted to ICU, 1.44 times more likely to require ventilation, and 2.88 times more likely to be classed as severe or critical, when compared to patients without diabetes.AA Further, the researchers found that patients in China, Korea and the Middle East were at higher risk of death than those from EU countries or the US. They suggest this may be due to differences in healthcare systems and affordability of healthcare. Diabetes is a serious medical condition where blood sugar levels are too high. In 2021, approximately 537 million adults between the 20-79 years were living with diabetes, according to the International Diabetes Federation. The total number of people living with diabetes is projected to rise to 643 million by 2030 and 783 million by 2045. While diabetes increased severity of Covid, a recent study published in the journal Diabetologia, also showed people who have had Covid-19 infection are at increased risk of developing Type 2 diabetes. "In light of the ongoing pandemic, strengthening outpatient diabetes clinics, ensuring consistent follow up of patients with diabetes and optimising their glycaemic control could significantly increase the chances of survival following a Covid infection," Kastora noted.
