My dad is still clueless why he was attacked: Justice Shetty's son

Bengaluru, Apr 30: The Karnataka government on Thursday decided to allow migrant workers, tourists, students and others stranded in different parts of the state due to the ongoing lockdown to return to their native places, a day after the Centre issued guidelines for the process.

This will be a one-time movement and the government would arrange buses for those in need but they should bear the expenses, Law and Parliamentary Affairs Minister J C Madhuswamy said. He also said people willing to return to the state would have to undergo tests for COVID-19. The decision was taken at the state cabinet meet and it might come into effect from Friday as the Chief Secretary will have to issue an official order, he said.

"Prime Minister Narendra Modi had taken decision on movement of people and the Centre had issued a circular in this regard. Following this we have decided to permit interstate and inter-district movement," he told reporters here.

Travel expenses should be borne by those willing to return and if they want the government can provide buses from the state transport corporations. The Union Ministry of Home Affairs on Wednesday issued orders allowing migrant workers, tourists, students and other people stranded in different parts of the country to move to their respective destinations with certain conditions, giving a big relief to the distressed people. Decision on opening of salons and liquor shops will be taken after May 3, he said.

Madhuswamy said permission would be given for one-time movement of labourers and others who want to go from one district to other for work or any other purpose. Those operating industry or establishment and want to move from place to place for management purpose will be given passes with strict scrutiny and through checks.

Responding to a question, the minister said, "we don't know yet how many are willing to go, where they will go, if some one asks for permission, we will permit." "One family or two or three people want to go, they can use taxi. If too many people want to go, we will provide facility through transport corporation buses," he said.

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.

Mangaluru, Jun 15: The case of two elderly Dubai returnees who are being treated for Covid-19 at the Wenlock Covid-19 Hospital has left doctors perplexed.

The two aged 76 and 81 men had arrived from Dubai on May 18 and 12 respectively and are at the hospital since one month. 

To everyone's surprise, six of their tests have come out positive though they have not shown any symptoms of SARS-CoV-2.
