A 26-country review compiled from 131 studies, the largest systematic review to date of children and young adults with COVID-19, has found that majority of children with Covid-19 fared well clinically compared to adults during the first four months of the pandemic.

While 19 per cent of the pediatric population with Covid-19 had no symptoms, 21 per cent exhibited patchy lesions on lung X-rays.


“Nearly 5.6 per cent suffered from co-infections, such as flu, on top of Covid-19, 3.3 per cent were admitted to intensive care units and 7 deaths were reported,” according to researchers from the Long School of Medicine at The University of Texas Health Science Center at San Antonio.

“Our data is compiled from 131 studies and encompasses 7,780 patients who span the pediatric age spectrum,” said study senior author Alvaro Moreira, assistant professor of pediatrics at UT Health San Antonio.

“Furthermore, we summarize treatments that were administered and offer an initial glimpse of a handful of patients who met the U.S. Centers for Disease Control and Prevention (CDC) criteria for multisystem inflammatory syndrome in children,” said Moreira in the study appeared in EClinicalMedicine, a journal of The Lancet.

The most frequent symptoms among kids, similar to the adult population, were fever and cough. Those were found in 59 per cent and 56 per cent of the pediatric population.

The number of children with excellent outcomes surprised the research team.

“Although we are hearing about severe forms of the disease in children, this is occurring in very rare circumstances,” said Moreira.

Laboratory measures that were consistently abnormal in pediatric Covid-19 patients included inflammatory markers such as creatine kinase, interleukin-6 and procalcitonin.

Thankfully, only a small number of patients met inclusion for multisystem inflammatory syndrome in children. Their disease paralleled the extreme forms of COVID-19 seen in adults.

“Children with systemic inflammation had a significant decrease in the amount of lymphocytes in their blood,: informed Moreira.

“COVID-positive children who didn’t have the extreme form of the disease had 42 per cent lymphocytes in their blood, versus 11 per cent in children with the multisystem syndrome”.

Lymphocytes are one of the main types of immune cells in the body.

Kidney failure was seen in nine pediatric patients, liver failure also in nine and shock in 19. Mechanical ventilation was required by 42 patients, the authors wrote. (IANS)

Japan launched its new satellite, QZS-1R.

Japan has successfully launched a new navigation satellite into orbit that will replace its decade-old navigation satellite.

The satellite, QZS-1R, was launched onboard an H-2A rocket that lifted off from the Tanegashima Space Center at 10.19 p.m. on Monday night, Mitsubishi Heavy Industries said in a statement.

The company builds and operates H-2A rockets the Japan Aerospace Exploration Agency (JAXA).

QZS-1R is a replacement for Quasi-Zenith Satellite System 1 satellite first launched in 2010. “It was a really beautiful launch," the company said in a tweet after a successful lift-off.

"H-IIA F44 flight proceeded nominally. Approximately 28 minutes 6 seconds after launch, as planned, the payload separated from the launch vehicle," the statement said.

The official QZSS website lists four satellites in the constellation: QZS-1, QZS-2, QZS-3 and QZS-4, Space.com reported.

The QZSS constellation will eventually consist of a total of seven satellites that fly in an orbit passing through a near-zenith (or directly overhead) above Japan, and QZS-R1 is meant to share nearly the same transmission signals as recent GPS satellites, according to JAXA.

It is specially optimised for mountainous and urban regions in Japan, JAXA said.

Mitsubishi's H-2A 202 rocket launch system has been operational since 2003 and has sent satellites to locations such as Venus (Akatsuki) and Mars (Emirates Mars Mission).

The latest H2-A rocket launch is the first since November 29, 2020, when Japan launched an advanced relay satellite with laser communications tech into orbit, the report said. (IANS/JB)

Fireworks light up the night sky

Everyone loves firecrackers, even the most environment-friendly advocates cannot hide their joy when they see these delightful lights colour the skies. India celebrates Diwali in the true spirit of her culture and heritage by spraying the navy-blue skies with sparkling hues of gold, silver, red, and green. Firecrackers are not just a tradition in this country, they are a legacy.

The original connotation one makes with fireworks in China. The elaborate Chinese celebrations with dragons and zapping firecrackers have left their mark in human memory, but the use of fireworks is not limited to heralding the Chinese New Year. All over the world, fireworks have come to symbolise the ultimate celebration. During Diwali in India, this spirit is re-ignited every year.

A visitor looks at statues of the 'Royal treasures of Abomey kingdom' on display at the Musee du quai Branly in Paris on Sept. 10, 2021, part of 26 artworks set to be restituted to Benin later in the year.

PARIS — In a decision with potential ramifications across European museums, France is displaying 26 looted colonial-era artifacts for one last time before returning them home to Benin.

The wooden anthropomorphic statues, royal thrones and sacred altars were pilfered by the French army in the 19th century from Western Africa.
