Cracker injuries darkenfestival of lights'; many hospitalised in Karnataka

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.

New Delhi, Apr 9: The Delhi Police has traced Tablighi Jamaat leader Maulana Saad Kandhalvi, who has been on the run after an FIR was registered against him for organising a religious gathering last month despite restrictions to combat the coronavirus, sources said on Wednesday.

The cleric has been traced to Zakir Nagar in southeast Delhi, sources said.

His lawyer Tauseef Khan, however, said Saad is under self-quarantine and will join investigation after his quarantine period is over.

On March 31, Delhi Police's Crime Branch lodged an FIR against seven people, including the cleric, on a complaint by Station House Officer Nizamuddin for holding the congregation here allegedly in violation of the orders against large gathering and not maintaining social distancing to contain the spread of coronavirus.

A day later, the Delhi Police's Crime Branch wrote to Saad and others, seeking the details under Section 91 of the Code of Criminal Procedure. A second notice was also issued to him this week.

"Saad is currently under self-quarantine and will join investigation once the period of 14 days gets over," his advocate, Tauseef Khan, told PTI.

Saad's quarantine is expected to end next week.

His lawyer said a reply to the second notice will be given soon.

In an audio message last week, Saad said he was exercising self-quarantine after several hundreds who visited the Tablighi Jamaat's Nizamudddin markaz tested positive for coronavirus.

Visited by thousands last month, the Nizamudddin centre also turned out to be a hotspot for spread of coronavirus not only in national capital and country.

According to the FIR, the Delhi Police contacted the centre on March 21 and reminded them of the government order that prohibited any political or religious gathering of more than 50 people.

However, no one paid any heed to the police's direction, it said. Moreover, an audio recording purportedly of Saad was found in circulation on WhatsApp on March 21, in which he was heard asking his followers to defy the lockdown and social distancing and to attend the religious gathering of the Markaz.

On March 24, the government ordered 21-day nationwide lockdown and restricted any social, political or religious gathering.

The same day a meeting was held at Hazarat Nizamuddin police station between SHO and officer bearers of the centre.

The meeting was attended by Saad, Mohammad Ashraf, Mohammad Salman, Yunus, Mursaleen Saifi, Jishan and Mufti Shehzad and they were informed about lockdown orders.

So far, several hundred cases of COVID-19 cases across the country have been found to be linked to the Tablighi Jamaat congregation held in Delhi last month.

More than 25,500 Tablighi members and their contacts have been quarantined in the country after the Centre and the state governments conducted a "mega operation" to identify them.

At least 9,000 people participated in the religious congregation in Nizamuddin. Later, many of the attendees travelled to various parts of the country.

Earlier, Thakur had allegedly made slogans like "Desh ke gaddaro ko, goli maaro saalo ko (shoot the traitors)" multiple times during a public meeting in Delhi. He had also faced a show-cause notice from the Electon Commission, asking a response from him on January 30.
