Covid 19

Interestingly, it may even exceed death rates from the viral infection itself, said scientists at Northwestern University.Secondary bacterial infection of the lung (pneumonia) was extremely common in patients with Covid, affecting almost half the patients who required support from mechanical ventilation. Our study highlights the.

Bell's palsy is the sudden onset of one-sided facial paralysis. In the majority of cases (70 per cent), the condition resolves itself within six months without treatment and the chance of recovery is even higher (90 per cent) if patients receive early treatment with corticosteroids.

The team, led by those from the National Research University Higher School of Economics (HSE), discovered that the likelihood of a substitution occurring at a specific site of the SARS-CoV-2 genome is dependent on concordant substitutions occurring at other sites. This explains why new and more contagious variants of the virus can emerge unexpectedly and differ significantly from those that were previously circulating, they wrote in the paper published in the journal eLife.

Climate change affected the mental health and wellbeing of children and adolescents. Young people with a mental illness and without social support are at an increased risk of climate change induced mental ill-health. Covid-19 resulted in a similar increase in psychological distress. Incidents of depression, anxiety and insomnia have increased due to the upheavals that people were experiencing including loss of livelihood and breaking of social bonds.

The research from University College London used MRI scanning to compare the brain activity of people with long Covid who lost their sense of smell, those whose smell had returned to normal after Covid infection, and people who had never tested positive for Covid-19. Published in eClinicalMedicine, the observational study found that.

Sudden sensorineural hearing loss (SSNHL) -- also known as sudden deafness -- is a little known and poorly understood side effect of Covid-19 that is not even listed as a common symptom by doctors, said Kim Gibson, a fully vaccinated nursing lecturer at the University of South Australia. Gibson, a registered nurse with a clinical background in neonatal intensive care, developed acute hearing loss in one ear, along with vertigo and tinnitus five weeks after experiencing a mild Covid infection in 2022.

The findings, published in JAMA Network Open, are based on results from a comprehensive assessment of brain development. "The study, which used a more rigorous method to evaluate babies born during the pandemic, provides further reassuring evidence that having a mild or asymptomatic case of Covid during pregnancy does not affect brain development in infants," said lead author Dani Dumitriu, Assistant Professor of paediatrics and psychiatry at Columbia University.

The team from Copenhagen University Hospital in Denmark developed a dried blood spot test, in which a single spot of blood is tested for nucleic acid from the three viruses. "We've shown that using existing hospital equipment, it is possible to detect HIV, hepatitis B and hepatitis C from a single drop of blood," said Stephen Nilsson-Moller at the varsity's Department of Clinical Microbiology.

T cells are immune cells that are unleashed when the immune system detects foreign pathogens. To understand how Omicron breaks all these barriers, a team from the Yale University in the US, measured activity of MHC (major histocompatibility complex) molecules that present fragments of viruses for recognition by appropriate T cells.

According to the Global Burden of Disease, nearly a quarter (24.8 per cent) of all deaths in India is due to cardiovascular diseases (CVD). Recent reports showed many young celebrities, artistes, athletes, sportspersons -- who usually remain fit and have no history of CVD -- face heart attacks, while some also succumbed to it.
