Ullal stabbings: One held, more arrests likely; 'All 5 victims are innocents'

University of Oxford researchers have claimed that a cheap and widely available drug called dexamethasone can help save the lives of patients who are seriously ill with coronavirus.

Scientists working on the Recovery Trial found the drug could help patients on ventilators and oxygen, but had no effect on those who did not need help breathing.

“Based on these results, one death would be prevented by treatment of around eight ventilated patients or around 25 patients requiring oxygen alone,” researchers said in a statement.

Matt Hancock, the health secretary, tweeted: “This global first exemplifies the power of science.”

“I’m absolutely delighted that today we can announce the first successful clinical trial for a treatment for Covid-19,” Mr Hancock said.

Recovery Trial experts said a randomised group of 2,104 patients was given 6mg of dexamethasone per day for 10 days, while another group of 4,321 were given normal treatment.

Dexamethasone reduced deaths by one-fifth in patients on oxygen feeds and by one-third in those who needed a ventilator to breathe, preliminary results showed.

Mr Hancock added: “This is a huge step forward and it’s because we’ve backed the science.”

Martin Landray, professor of medicine and epidemiology at the Nuffield Department of Population Health, University of Oxford, and one of the trial’s chief investigators, said in a statement: “These preliminary results from the Recovery Trial are very clear – dexamethasone reduces the risk of death among patients with severe respiratory complications.

“Covid-19 is a global disease – it is fantastic that the first treatment demonstrated to reduce mortality is one that is instantly available and affordable worldwide.”

Bengaluru, Jul 4: A young woman doctor at the Kempegowda Institute of Medical Sciences, Bengaluru, who had raised an alarm about faulty PPE kits and shortage of N95 masks, has tested positive for the covid-19.

Taking note of this, Mysuru-Kodagu MP Pratap Simha brought the issue to the attention on Medical Education Minister Dr K Sudhakar on Twitter. Tagging the minister, the MP tweeted, “For your information and I feel, it is a genuine concern.” “Amulya Gowda treated Covid patients at KIMS.

Karnataka Medical Association took to social media to express concern over the development. In a Facebook post it wrote: "Amulya C Gowda is a frontline worker who risks her life every single day. Last week she raised an alarm about faulty PPE kits and shortage of N-95 masks. But the Administrative Medical Officer (AMO) at KIMS, shunned and chastised her for raising this issue. Ever since, she has been buying her own N-95 masks. Today, she tested positive for Covid-19 and appealed to the Hospital authorities and raised her genuine concerns over the faulty protective gear, but she was again harassed and humiliated for raising the issue."

Dr DH Ashwath Narayana, Medical Superintendent, KIMS Hospital, said that all PPE kits at KIMS were certified by SITRA (South India Textiles Research Association), Coimbatore and that they had purchased N-95 masks available in the market. "One cannot claim faulty PPEs are the reason for testing positive. We have purchased whatever PPE kits are available in the market. Healthcare workers across hospitals, private and government, and policemen are also getting infected."

As the new rules by the state government allow healthcare workers home isolation, Narayana said the doctor is recuperating at home and that she is doing fine.

Medical education minister Dr K Sudhakar tweeted, "Doctors are our frontline warriors battling the pandemic. Government has taken all necessary measures to ensure safety of our doctors. I have taken note of supply of defective masks and PPE kits to KIMS doctors and ordered an enquiry. Management will be held responsible if found guilty."
