Modi govt to declare Zakir Naik's NGO outlawed body for 5 years

Mangaluru, Mar 22: A video being circulated in the social media purportedly of a man infected with COVID-19 at a hospital here is fake, its authorities said.

The video which shows a youth, dressed in pink trousers and wearing a mask, struggling to breathe on a blue hospital bed, had gone viral after which the Wenlock hospital issued a clarification.

The video started circulating after Dakshina Kannada Deputy Commissioner made public Sunday that a person has tested positive for coronavirus at the hospital.

"A video of a patient convulsing on a hospital bed is being circulated on social media. This video is not of Wenlock hospital. Besides, we do not use blue beds," the hospital said in a statement, adding that they will file a complaint with the police regarding the video.

The first COVID-19 case in the district was confirmed at the hospital on Sunday.

The 22-year old man who came here from Dubai was tested positive and is under treatment in the isolation ward.

Washington D.C., May 8: The prime time for brain development in a child's life is the first year, where the infant spends most of the time asleep. It is the time when neural connections form and sensory memories are encoded.

However, when sleep is disrupted, as occurs more often among children with autism, brain development may be affected, too.

New research led by the University of Washington finds that sleep problems in a baby's first 12 months may not only precede an autism diagnosis but also may be associated with altered growth trajectory in a key part of the brain, the hippocampus.

The study, which was published in the American Journal of Psychiatry, researchers report that in a sample of more than 400 taken of 6- to 12-month-old infants, those who were later diagnosed with autism were more likely to have had difficulty falling asleep.

It also states that this sleep difficulty was associated with altered growth trajectories in the hippocampus.

"The hippocampus is critical for learning and memory, and changes in the size of the hippocampus have been associated with poor sleep in adults and older children.

As many as 80 per cent of the children with autism spectrum disorder have sleep problems," said Annette Estes, director of the UW Autism Center and senior author of the study.

"In our clinical experience, parents have a lot of concerns about their children's sleep, and in our work on early autism intervention, we observed that sleep problems were holding children and families back," added Estes, who is also a UW professor of speech and hearing sciences.

"It could be that altered sleep is part-and-parcel of autism for some children. One clue is that behavioural interventions to improve sleep don't work for all children with autism, even when their parents are doing everything just right. This suggests that there may be a biological component to sleep problems for some children with autism," said Estes.

To consider links among sleep, brain development, and autism, researchers at the IBIS Network looked at MRI scans of 432 infants, surveyed parents about sleep patterns, and measured cognitive functioning using a standardized assessment.

At the outset of the study, infants were classified according to their risk for developing autism: Those who were at higher risk of developing autism -- about two-thirds of the study sample -- had an older sibling who had already been diagnosed.

Infant siblings of children with autism have a 20 per cent chance of developing autism spectrum disorder -- a much higher risk than children in the general population.

In the current study, 127 of the 432 infants were identified as "low risk" at the time the MRI scans were taken because they had no family history of autism.

They later evaluated all the participants at 24 months of age to determine whether they had developed autism. Of the roughly 300 children originally considered "high familial risk," 71 were diagnosed with autism spectrum disorder at that age.

Problems with sleep were more common among the infants later diagnosed with an autism spectrum disorder, as were larger hippocampi. No other subcortical brain structures were affected, including the amygdala, which is responsible for certain emotions and aspects of memory, or the thalamus, a signal transmitter from the spinal cord to the cerebral cortex.

The authors note that while parents reported more sleep difficulties among infants who developed autism compared to those who did not, the differences were very subtle and only observed when looking at group averages across hundreds of infants.

Sleep patterns in the first years of life change rapidly as infants transition from sleeping around the clock to a more adult-like sleep/wake cycle. Until further research is completed, Estes said, it is not possible to interpret challenges with sleep as an early sign of increased risk for autism.

Chmarajanagara, Feb 23: In order to control and keep a tab on the activities within the forest area and after the bitter experiences with frequent forest fires, like the one in Bandipur Tiger Reserve last year Karnataka Forest Department officials have decided to use drones to prevent the occurrences of such wildfires, and to use drones to nab trouble makers and take timely action to put out or prevent forest fires, especially during the summer season.

The department of forest has been working on using drones and setting up a centre in Mysuru or Chamarajanagar to monitor three crucial tiger reserves — Bandipur, Nagarhole, and BRT.
