Three youths from Dakshina Kannada perish in Goa

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.

Bengaluru, May 29: Karnataka Law and Parliamentary Affairs Minister J C Madhuswamy on Thursday said the Centre has objected to the state's decision to increase working days at factories, and the matter would be discussed in the next cabinet meeting.

"....the Centre has raise objection to extending working days and has said it should be brought down. We will amend it....I will share the details after the next cabinet meet, the matter did not come up today (Thursday), we have received the letter," Madhuswamy told reporters in response to a question after the cabinet meeting.

He noted that a couple of states that had increased the working hours have withdrawn it. The Karnataka government had, on May 22, issued a notification allowing factories to extend working hours upto 10 hours a day and 60 hours a week till August 21. The extension of work hours is from the existing eight hours a day and 48 hours a week.

Pointing out that while announcing COVID-19 relief package, the Chief Minister B S Yediyurappa had announced Rs 5,000 per acre for maize farmers, Madhuswamy said while issuing the circular which mentioned that relief would be applicable to rabi crop, as it would not benefit many farmers.

Now, it has now been decided to give Rs 5,000 per acre to all maize farmers, irrespective of rabi or kharif. There were also several rules and regulations for barbers, autorickshaw and taxi drivers among others to claim their one-time compensation of Rs 5,000, the Minister said.

"We have decided to relax most of them (rules) other than those essential and give compensation, as regulations wouldn't have benefited many," he said. With five nominated seats of legislative council falling vacant on June 23, the cabinet has authorised the Chief Minister to nominate for 5 seats.

The cabinet also gave post-facto approval for Karnataka Repealing of Certain Enactments and Regional Law Bill 2020 that has been passed by the legislature.

Bengaluru, Apr 5: Fake news spreads faster and more easily nowadays through the internet, social media and instant messaging and such news about the COVID-19 pandemic have been labeled a dangerous “infodemic”.

These messages may contain useless, incorrect or even harmful information and advice, which can hamper the public health response and add to social disorder and division.

Asking people to avoid fake news on COVID-19, Hemant Nimbalkar IPS, IGP and Additional Commissioner of Police (Administration), shared a photo on his Twitter page and wrote, “One Mask For Ear Too"
