Don't mess with govt image: Modi's message to Smriti Irani

Mangaluru, Apr 16: An old refrigerator has been turned into a "disinfection chamber" by researchers who are striving to come up with solutions to tackle the spread of coronavirus.

Dr Arun M Isloor, head of Chemistry Department, National Institute of Technology Karnataka (NITK), Surathkal, along with research scholar Syed Ibrahim has come up with the device which can disinfect items kept inside it.

"We have named this as ZERO-COV," Dr Isloor said.

He says the device ensures 99.9 per cent destruction of microorganisms present on the surface of items.

"We can keep items like vegetables, currency notes, books or envelopes inside the chamber. Switching on the chamber for 15 minutes ensures 99.9 per cent destruction of microorganisms present in the surface of the items," Dr Isloor added.

Bengaluru, Jan 21: A private hospital in Bengaluru, the capital of Karnataka, on Tuesday claimed that it has successfully performed a live liver transplant on a Jehovah's Witness from Nigeria, by not using blood or blood products, in order to protect the patient's religious beliefs.

It is said that Jehovah's Witnesses are followers of a Christian faith that prohibits the use of blood or blood products during their treatment. Gehojadak (37), a Jehovah's Witness follower, had developed decompensated liver disease and visited more than three countries seeking treatment over the last four years but was turned away by most doctors due to the highly risky nature of surgery, Aster CMI Hospital said.

The surgery was challenging compared to a normal liver transplant because in order to protect the patient's religious beliefs, the medical team could not use blood or blood products (Fresh frozen plasma, Cryoprecipitate, Platelets etc), it said in a release, adding that very few such surgeries have been successfully conducted worldwide.

The patient's brother was the donor, the hospital said, adding, without a liver transplant, Gehojadak's chances of survival were less than 10 per cent over the next two years. A team of liver specialists from the Hospital thoroughly reviewed the patient's medical history before recommending a bloodless liver transplant and charted out a feasible pathway to make the surgery a success.

"This transplant was especially challenging as we did not have the safety net (of using blood) even if the patient's life was at risk due to their advance directive. We have performed other non-transplant liver surgeries in Jehovah's Witnesses and this gave us the confidence to take on Gehojadak's transplant," Dr Rajiv Lochan, Consultant Liver Transplant Surgeon, said.

The critical surgery took a 12-hour period to complete where two teams of specialists with close to 25 doctors including anaesthetists, intensivists worked in absolute sync with each other and Gehojadak finally received a life-saving liver transplant, the Hospital said. In a period of two weeks, the patient and his brother were fit enough to go home and were discharged from the hospital.

"Even if their haemoglobin levels dropped to life-threatening levels, the patients were clear that they would not accept a blood transfusion. Keeping the limitations in mind, the most effective treatment path was planned, and we spent close to two months preparing the patients for surgery," Arun V, Consultant Anesthesiologist said. The hospital arranged customised artificial products like synthetic drug molecules, to conduct a bloodless liver transplant, he added.

Bengaluru, Mar 27: Oncologist Dr. Vishal Rao, HCG Hospital Bengaluru on Friday said that human body cells release interferon chemical to kill viruses but it cannot be released by cells in the case of COVID-19 cases, leading to weak immune system. However, a therapy of specific concoction could be useful in treating COVID-19 patients.

"We got hold of some preprint suggesting that interferon is effective in COVID19," said Rao.

Speaking to news agency, he continued saying "When we withdraw blood for regular check-ups, we get buffy coat which can be used to take out cells and form interferon. These two chemicals and some other cytokines, in a specific concoction, could be potentially very useful in treating COVID-19 patients."

Rao said that they have built a concoction of cytokines which can be injected to reactivate immune system in COVID-19 patients.

"We are in a very initial stage and hope to be ready with its first set by this weekend. We have applied to the governement for an expedited review. We have also presented this before the state government" said Rao.

"We have a team of infection specialist, ICU team and other...all of us have worked together to build something that we believe. We want to serve the society at this hour of need," he added.

Dr Rao clarified that this is not a vaccine and this particular interferon therapy does not help to prevent the infection of COVID-19. However, this is focused and targeted towards COVID-19 positive patients or those who have just incubated the virus.

"We believe that in early stages as well as the patients who have just incubated, this particular therapy of interferon gama and other concoction of cytokines could be an effective method. In the late stages we are looking at specific dosage of the cells which are our own body cells which can actually be affective and could also be of use for the ventilator patients," he added.

Meanwhile, Dr Gururaj, Immunologist and Scientist told ANI that they are trying to cover two aspects, one is the early stage patients where they are trying to improve their immune systems.

"As Dr Vishal said, we are trying to see whether we can use the cytokines from our own immune cells which is a natural process but it is hampered in infected patients," said Dr Gururaj.

"In the last phase we are using cells which are used from the bone marrow of the patient or donors. We can use those cells to reduce the inflation and so called cytokines release syndrome which is basically the inflammatory response of the body," he added.
