Sabarimala Row: Hurling of bombs, setting ablaze party offices continue in Kerala

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.

Nanded, May 24: In a sensational incident, a Lingayat seer from Karnataka was found murdered in his mutt in the Nanded district of Marathwada region of Maharashtra on Sunday.

The seer, who was strangled to death, has been identified as Shivacharya Nirvanarudra Pashupatinath Maharaj, the founder-spiritual head of Nirvanji Pashupatinath Mutt.

Addressing media persons, Nanded Superintendent of Police Vijaykumar Magar, the prime suspect, Sainath Langote first killed his accomplice Bhagwan Shinde and then went to the ashram late on Saturday.

He entered Shivaharya Maharaj's bedroom where he was resting and threw chilli powder in his eyes, blinding him.

Then he quickly grabbed cash of Rs 69,000, his laptop and other valuables in the bedroom worth approximately Rs.1.50 lakh, besides the seer's car keys.

As Shivacharya Maharaj attempted to grapple with him, Langote pinned him down and strangled him, then dragged his body to the sadhu's car parked outside and dumped it into the boot.

"He started the car and sped off towards the road outside, but the car crashed into the main gate of the ashram creating a noise, alerting the other sevaks sleeping inside the ashram," Magar said.

Around 8-10 other ashram sevaks rushed outside to check the ruckus and when they saw their seer's belongings and his body in the car trunck, they attempted to stop Langote, but he gave them the slip.

A short distance away, Langote managed to steal a motorbike and sped off into the darkness and hours later, the police found the body of his accomplice Shinde from a nearby school premises, Magar said.

In view of the sensitivity of the incident, Magar said around five crack teams were formed which fanned out into the district and managed to catch Langote this afternoon.

"The prima facie motive for the seer's murder was clearly robbery and the second killing could be due to rivalry or some differences among them. The absconder suspect has been caught by a police team. We will interrogate him and get further details of the crime," Magar said.

Nanded Congress strongman and PWD Minister Ashok Chavan appealed that the murder should not be politicized, since the police investigations are underway and the autopsy report is awaited.

He said the deceased sadhu belonged to the Lingayat caste, and both Shinde and Langote who belonged to the same community were his followers.

Shivacharya Maharaj had come to Nanded over a decade ago and set up the ashram which he ran along with a band of followers.

Thrissur, Feb 11: The latest test result of the woman medical student, who arrived here from China's Wuhan region and was the first positive case from India for the novel Coronavirus (nCoV), has come out negative, health officials said on Monday.

Her condition was "stable", they said.

According to the state health department as of now, 31 people are in isolation wards across various hospitals in the state.

"The blood test result of the first patient from Thrissur, from the National Institute of Virology (NIV) testing centre at Alappuzha, shows a negative result.

But we need confirmation from the NIV at Pune," a senior medical officer told news agency.

After the first positive case was reported from Thrissur, two other Keralite students from Wuhan, the epicentre of the virus, had tested positive in Alappuzha and Kasaragod districts.

The health department had earlier said those in isolation wards of various hospitals in the state have come down to 34.

"A total of 3,367 are under observation across the state, of which 3,336 are under home quarantine," a release issued by the health department said.

The department has already sent at least 364 samples for testing at the NIV at Pune and so far 337 results have returned negative.

The ''state calamity'' alert, which was declared on February 3, was withdrawn on Friday after no new positive cases of infection were detected.
