  • DNA test can identify pneumonia in patients with severe Covid
    London, January 15 (IANS) Researchers have developed a DNA test to quickly identify secondary infections in Covid-19 patients, who have double the risk of developing pneumonia while on ventilation. For patients with the most severe forms of Covid-19, mechanical ventilation is often the only way to keep them alive, as doctors use anti-inflammatory therapies to treat their inflamed lungs. However, these patients are susceptible to further infections from bacteria and fungi that the
  • Discrimination ups anxiety risk regardless of genetics
    New York, January 15 (IANS): Regardless of genetic risks, exposure to discrimination in life plays a significant role in developing anxiety and related disorders, suggests a new study. Published in the Proceedings of National Academy of Sciences journal, the study determined that even after controlling genetic risk for anxiety, depression and neuroticism, people reported greater discrimination experiences. "The results demonstrate that discriminatory experiences can potentia
  • Depression, stress can reduce vaccine efficacy
    New Delhi, January 14 (PTI): Depression, stress and loneliness can weaken the body's immune system, and lower the effectiveness of certain vaccines, including the new Covid-19 preventives that are in development and the early stages of global distribution, scientists say.  According to a report accepted for publication in the journal Perspectives on Psychological Science, simple interventions, including exercise and getting a good night's sleep in the 24 hours before va
  • Past COVID-19 infection gives 5-month immunity, but risk exists: UK study
    London, January 14 (PTI): An official UK study released on Thursday concludes that a past COVID-19 infection provides some immunity for at least five months, but people may still carry and transmit coronavirus. The Public Health England (PHE) analysis found that naturally acquired immunity as a result of past infections provide 83 per cent protection against reinfection, compared to people who have not had the disease before. This appears to last at least for five months from fir
  • Being workaholic may increase depression, anxiety risk
    Moscow, January 14 (IANS): If you are a workaholic, then there are chances you may suffer negative mental and physical health outcomes such as depression, anxiety or sleep disorder, a new study suggests. The study, published in the International Journal of Environmental Research and Public Health, indicates that people with higher work addiction risk compared to people with low work addiction risk have twice the risk of developing depression.

  • Short term low-carb diet linked to Type-2 diabetes' remission
    New York, January 14 (IANS): Patients with Type-2 diabetes who follow a strict low carbohydrate diet for six months may experience greater rates of remission compared with other recommended diets without adverse effects, a new study suggests. Most benefits diminished at 12 months, but say doctors might consider short-term strict low carbohydrate diets for managing Type-2 diabetes, while actively monitoring and adjusting diabetes medication as needed, the researchers, including Joshu
  • SARS-CoV-2 can infect neurons, damage brain tissue: Study
    NEW YORK, JANUARY 13 (IANS): Researchers have discovered that SARS-CoV-2 can directly infect the central nervous system and have begun to unravel some of the virus's effects on brain cells. The study, that used both mouse and human brain tissue, indicates that SARS-CoV-2 can affect many other organs in the body, including, in some patients, the central nervous system, where infection is associated with a variety of symptoms ranging from headaches and loss of taste and smell to i
  • Novel coronavirus may resemble common cold in future, scientists predict
    New Delhi, January 13 (PTI): SARS-CoV-2, the virus that causes COVID-19, may resemble the mild cold-causing coronaviruses that currently circulate in humans if it becomes endemic and most people are exposed in childhood, according to a study. The modelling study, published on Tuesday in the journal Science, is based on research of the four common cold coronaviruses and SARS-CoV-1. The analysis of the immunological and epidemiological data for these viruses helped the researchers
  • Two doses of vaccine will be needed 28 days apart: Govt
    New Delhi, January 12 (PTI): There will be a gap of 28 days between two doses of COVID-19 vaccine and its effectiveness will begin 14 days after the second dose, the Health Ministry said on Tuesday. Addressing a press briefing, Union Health Secretary Rajesh Bhushan said vaccine effectiveness will be seen only after 14 days.

  • Higher coffee intake may reduce prostate cancer risk
    Beijing, January 12 (IANS): Do you crave for coffee everyday? If so, then there's a good news for you. A new study suggests that drinking several cups of coffee every day may be linked to a lower risk of developing prostate cancer. The study, published in the journal BMJ Open, showed that each additional daily cup of the brew was associated with a reduction in relative risk of nearly 1 per cent. "This study suggests that increased coffee consumption may be associated wit
  • Stress in expecting mothers impact children: Study
    New York, January 12 (IANS): Expecting mothers, stop worrying or taking any kind of stress as it may affect your baby's chance of developing disease, a new study suggests. According to a study, published in the journal scholarly journal Biological Psychiatry, stress on an expectant mother could affect her baby's chance of developing disease -- perhaps even over the course of the child's life. Psychosocial factors creating stress -- such as lack of social support, lone
  • 'Why COVID-19 lasts longer, causes more damage than typical pneumonia decoded'
    New Delhi, January 12 (PTI): In a first-of-its-kind study, researchers have analysed immune cells from the lungs of severe COVID-19 patients in a systematic manner and compared them to those from patients with pneumonia from other viruses or bacteria, findings which shed light on how the novel coronavirus infection spreads. Instead of rapidly infecting large regions of the lung, the coronavirus sets up shop in multiple small areas and hijacks the host's immune cells to spread ac
  • Holding breath may increase Covid infection risk: IIT researchers
    Chennai, January 11 (IANS): Researchers, at the Indian Institute of Technology (IIT) Madras, have found that the process of virus-laden droplets being transported into deep lung increases with decreasing breathing frequency. The team modelled the breathing frequency in a laboratory and found that low breathing frequency increases the time of residence of the virus and therefore, it increases chances of deposition and consequently the infection. Also, the multi-scale lung structure h
  • Novel tech may help cancer patients manage symptoms
