A new study suggests that tears of patients with and without ‘ocular manifestations’ of COVID-19 can be a potential source of infection. Ocular manifestation refers to an eye condition that is directly or indirectly caused by a disease in another body. The study was published in the latest edition of the Indian Journal of Ophthalmology. The primary transmission route of ...

Delta variant is identified as the leading cause of breakthrough infections globally among vaccinated individuals. The Delta variant has also mutated to Delta AY.1, AY.2, and AY.3 variants. Of these, Delta AY.1 variant (also known as Delta Plus) was first detected in India in April 2021 and subsequently in twenty other countries. A new study by the Indian Council of ...

Long COVID is a long-term syndrome that emerges in some people after COVID-19 infection. COVID-19 long-haulers experience many symptoms, majorly neurological problems, which indicate nerve cell damage in the body. According to a new study, nerve damage and a buildup of immune cells in the cornea may be a sign of long COVID. Preliminary evidence from new studies suggests that ...

A recent study by the researchers from South Korea revealed that mixed vaccination of first AstraZeneca followed by a Pfizer COVID-19 shot boosted neutralizing antibody levels by six times compared with two AstraZeneca doses. The study researchers included 499 medical workers, out of which 100 received mixed doses, 200 received 2 doses of the Pfizer/BioNTech shot, and the remaining participants ...

Coronavirus disease 2019 (COVID-19) is associated with acute respiratory distress syndrome (ARDS) and cardiovascular complications, including myocarditis, severe arrhythmias, acute coronary syndromes, and pulmonary embolism. Researchers performed a study to identify the clinical conditions and echocardiographic parameters associated with in-hospital mortality in COVID-19. According to the study, transthoracic echocardiography (TTE) might be a useful tool in the risk stratification of ...

Azithromycin, a broad-spectrum antibiotic, is widely prescribed as a treatment for Covid-19 around the world. According to the new study, this commonly prescribed drug for Covid-19 is no more effective than a placebo in preventing COVID-19 among non-hospitalized patients and may increase their chance of hospitalization. The findings of the research were published in the Journal of the American Medical ...

Covid-19 is associated with inflammation and abnormal clotting in the blood vessels, particularly in the lungs, and is believed to contribute to severe disease and death progression. According to a study, administering a full dose of a standard blood thinner (heparin) early to moderately ill hospitalized patients with Covid-19 could halt the formation of blood clots and reduce the risk ...

The Food and Drug Administration (FDA) is expected to announce a new warning for Johnson & Johnson's COVID-19 vaccine, following preliminary reports of a rare nerve condition developed in a few people who received the shot. Through a symptom monitoring system called the Vaccine Adverse Event Reporting System, regulators have found 100 suspected cases of Guillain-Barré syndrome, but the reports ...

Pfizer and BioNTech have recently announced that they would seek regulatory authorization for a third dose of their Covid-19 vaccine. The decision was taken based on drop-offs in efficacy seen in Israel after six months. The companies believe people may need a third dose within 6 to 12 months after full vaccination. Initial data from an ongoing trial revealed that ...

Coronavirus attacks various human body organs; cellular entry for the virus requires two host cell surface proteins, namely ACE2 and TMPRSS2. Downregulation of one or both of these proteins can be a potential therapeutic approach for COVID-19. TMPRSS2 protein is a known target of the androgen receptor; androgen receptor activation increases TMPRSS2 levels in various tissues, most notably the prostate.A ...
