Diversity is the basis of our progress: Karnataka Governor

Bengaluru, May 25: Karnataka Chief Minister B S Yediyurappa on Monday greeted the Muslim brethren on the occasion of Eid-ul-Fitr, which is being celebrated in a subdued manner due to coronavirus related restrictions.

"Warm greetings of Eid-ul-Fitr. May this festival of peace and harmony bring happiness in life," Yediyurappa said in his message.

He congratulated the Muslim fraternity for cooperating with the authorities by offering prayers at home during the holy month of Ramadan and supporting the government to contain COVID-19.

"I hope the same trend will continue during the festivities of Eid-ul-Fitr too. I thank you all for your support in the fight against COVID-19," he said.

The Eid festivities were a low-key affair as Muslim brethren celebrated the festival indoors in view of lockdown to contain coronavirus on Monday.

People offered the special prayers inside their houses instead of performing it in mosques and Eidgah, the open field to perform prayers, and refrained from going out to greet each other.

As the Karnataka government has ordered Sunday Curfew throughout the lockdown-4 till May 31, the otherwise bustling markets in the urban areas of Karnataka remained shut.

People could not venture out to make necessary purchases on Sunday.

The Jama Masjid of Bengaluru at the City Market had asked the Muslims to offer prayers inside their houses and not go to the burial grounds to express their sentiments for the departed souls.

"Mass prayers are not allowed anywhere in Karnataka. Just five important persons managing the mosques offered the prayers. Similarly, people go to the graveyard to pray for the dead ones but this time we asked people to express their sentiments from inside their homes instead of going to the burial grounds," Maulana Maqsood Imran, the Khateeb-O-Imam, Jama Masjid, Bengaluru, told news agency.

He said, "coronavirus is spreading very rapidly in our country. If we don't follow the guidelines, it will not only cause trouble to us but also to the doctors and the government. It will be the biggest celebration if we abide by the norms."

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.
