RTI activist murder: Narendra Nayak gets threats for demanding justice

Thiruvananthapuram, Apr 14: Amid Covid-19 lockdown,

Keralites celebrated a low key "Vishu" ,the Malayalam new year, on Tuesday, hoping that days of plenty, prosperity and peace will return.

People woke up in the early hours to see the auspicious "Vishu kani", symbolising hope, promise and fine prospects they wish to have in the year ahead.

The ritual comprises arranging on platters auspicious articles like seasonal fruits, vegetables, flower, gold and clothes which together form the first sight when the family members wake up on the Vishu day.

Normally, Keralites dressed in their traditional attire throng temples across the state.

However, this year due to the lockdown restrictions, temple visits were given a go by.

The famed Sri Krishna temple at Guruvayur and the Lord Ayyappa shrine at Sabarimala witnesses heavy rush of devotees during the vishu day.

But pilgrims were not allowed inside and only temple officials and security personnel were present for the"Vishu kani".

Rehaman, a small time trader, said very few people have come out for vishu purchases due to the restricitons.

It is fine as it is for a good cause, while Radha, a young woman said she could not celebrate the festival.

"We have no money, no job. With whatever little we have, we are celebrating the festival", she said.

87-year-old Vilasini Nambiar, a retired college professor, said vishu has visited the state during a most bewildering time.

"It should however remind us that every mountain must have its valley, desert its oasis, every storm cloud its rainbow, every night its day.

We are prepared to believe that we will overcome this misfortune", she said.

President Ram Nath Kovind, Prime Minister, Narendra Modi, Home minister, Amit Shah, Kerala Governor, Arif Mohammed Khan and Chief Minister, Pinarayi Vijayan, were among those who greeted people on the occasion of Vishu.

Bengaluru, Apr 5: An elderly couple from Bengaluru

with a travel history to Dubai joined the list of coronavirus patients in the state, taking the total number of cases to 146, the health department said on Sunday.

The list includes four deaths and 11 discharges.

The 68-year old man and his 62-year old wife, hailing from Madiwala in the city, had returned from Dubai on March 22.

They were quarantined at a private hospital and have been asymptomatic.

Meanwhile, the government appealed to people who had attended the Tablighi Jamaat Congregation in New Delhi to contact 080-29711171 Arogya Sahayavani, the medical helpline number.

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.
