Thiruvananthapuram, Feb 1: With the first successful double hand transplant, Indian doctorshave registered a rare feat of carrying out the world's first hand transplant of a coloured skin and the first hand transplant in any developing country.

So far, only 110 successful hand transplants have been done, since the first one in France 13 years ago, in USA, European countries, China and Australia.

The honour for the rare feat goes to a team of surgeons at the Kochi-based Amrita Institute of Medical Sciences. The transplant was carried out on January 12 and 13 to a train accident victim - 30-year-old Manu, who received both the hands of a 24-year-old road accident victim.

"The operation lasted for 16 hours with more than 20 surgeons participating in the procedure. Each hand required connecting two bones, two arteries, four veins and about 14 tendons," saidDr. Subramania Iyer, Professor and Head of the Plastic Surgery Department.

"The immune suppressant drugs were started before the start of the surgery and continued after it. He was shifted to a transplant ICU. Careful monitoring of the blood supply to the hands was done and all precautions to prevent infections was instituted in the nursing. Another operation to replace an area of bad skin was done for his left hand on the second day," he added.

Dr. Iyer further said, "After14 days post-surgery, both the hands have been accepted by the recipient's body and he started regaining movements. He has been shifted out of the ICU and post-surgical rehabilitation process has started under supervision."

"Manu will be able to move his hands since his own muscles of the forearm are working to move the fingers. The sensations will return only slowly and is expected in three to four months. His immunosuppressant drugs (to prevent rejection of the transplanted hands) will have to be continued indefinitely, but at a reduced rate from three months," he added.

Dr. Iyer said, the current transplant is important, since follow up of the transplanted skin is done by the appearance of the skin and skin biopsies every month to see signs of rejection.

He said the details of the transplant have been added to the International Registry of Hand Transplants, which maintains stringent standards in the follow-up of these cases.

The entire expense for the transplant was borne by Mata Amritanandamayiu Math.

"This transplant has put the Indian scientific community among the league of a few developed nations in the field of composite tissue allotransplant," said Dr. Iyer.

Washington D.C, Feb 27: New research shows that adults who have low fruit and vegetable intake are more likely to be diagnosed with an anxiety disorder.

"For those who consumed less than 3 sources of fruits and vegetables daily, there was at least at 24% higher odds of anxiety disorder diagnosis," says the lead author of the Canadian Longitudinal Study, Karen Davison, who is a health science faculty member, nutrition informatics lab director at Kwantlen Polytechnic University, (KPU) and North American Primary Care Research Group Fellow.

"This may also partly explain the findings associated with body composition measures. As levels of total body fat increased beyond 36%, the likelihood of anxiety disorder was increased by more than 70%," states co-author Jose Mora-Almanza, a Mitacs Globalink intern who worked with the study at KPU.

"Increased body fat may be linked to greater inflammation. Emerging research suggests that some anxiety disorders can be linked to inflammation," says Davison.

In addition to diet and body composition measures, the prevalence of anxiety disorders also differed by gender, marital status, income, immigrant status and several health issues.

An important limitation of the study was that the assessment of anxiety disorders was mostly based upon self-reporting of a medical diagnosis.

"It is estimated that 10% of the global population will suffer from anxiety disorders which are a leading cause of disability," says Karen Davison

"Our findings suggest that comprehensive approaches that target health behaviours, including diet, as well as social factors, such as economic status, may help to minimize the burden of anxiety disorders among middle-aged and older adults, including immigrants," she concluded.

Washington, Aug 2: Children under the age of five have between 10 to 100 times greater levels of genetic material of the coronavirus in their noses compared to older children and adults, a study in JAMA Pediatrics said Thursday.

Its authors wrote this meant that young children might be important drivers of Covid-19 transmission within communities -- a suggestion at odds with the current prevailing narrative.

The paper comes as the administration of US President Donald Trump is pushing hard for schools and daycare to reopen in order to kickstart the economy.

Between March 23 and April 27, researchers carried out nasal swab tests on 145 Chicago patients with mild to moderate illness within one week of symptom onset.

The patients were divided into three groups: 46 children younger than five-years-old, 51 children aged five to 17 years, and 48 adults aged 18 to 65 years.

The team, led by Dr Taylor Heald-Sargent of the Ann & Robert H. Lurie Children's Hospital, observed, "a 10-fold to 100-fold greater amount of SARS-CoV-2 in the upper respiratory tract of young children."

15 countries with the highest number of cases, deaths due to the Covid-19 pandemic

The authors added that a recent lab study had demonstrated that the more viral genetic material was present, the more infectious virus could be grown.

It has also previously been shown that children with high viral loads of the respiratory syncytial virus (RSV) are more likely to spread the disease.

"Thus, young children can potentially be important drivers of SARS-CoV-2 spread in the general population," the authors wrote.

"Behavioral habits of young children and close quarters in school and daycare settings raise concern for SARS-CoV-2 amplification in this population as public health restrictions are eased," they concluded.

The new findings are at odds with the current view among health authorities that young children -- who, it has been well established, are far less likely to fall seriously ill from the virus -- don't spread it much to others either.

However, there has been fairly little research on the topic so far.

One recent study in South Korea found children aged 10 to 19 transmitted Covid-19 within households as much as adults, but children under nine transmitted the virus at lower rates.
