NITK gears up for 27th national convention of SPIC-MACAY

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.

Mangaluru, Mar 25: The Indian Council of Medical Research (ICMR) has so far given nod to three private laboratories in Karnataka for testing COVID-19. The ICMR comes under the Department of Health, Government of India

The three labs are KMC Hospital Manipal, Shankar Research Centre's laboratory, and SRL laboratory on Bowring Hospital Road at Shivajinagar, Bengaluru.

Eight private labs from Maharashtra, two from Haryana, three from Tamil Nadu, four from Delhi, and three each from Karnataka and Gujarat have been given permission. 

These labs have over 15,000 collection centres all over the country. Blood samples and throat swabs of coronavirus suspects can be given at these centres.

Washington, Apr 29: A US government panel on Tuesday called for India to be put on a religious freedom blacklist over a "drastic" downturn under Prime Minister Narendra Modi, triggering a sharp rebuttal from New Delhi.

The US Commission on International Religious Freedom recommends but does not set policy, and there is virtually no chance the State Department will follow its lead on India, an increasingly close US ally.

In an annual report, the bipartisan panel narrowly agreed that India should join the ranks of "countries of particular concern" that would be subject to sanctions if they do not improve their records.

"In 2019, religious freedom conditions in India experienced a drastic turn downward, with religious minorities under increasing assault," the report said.

It called on the United States to impose punitive measures, including visa bans, on Indian officials believed responsible and grant funding to civil society groups that monitor hate speech.

The commission said that Modi's Hindu nationalist government, which won a convincing election victory last year, "allowed violence against minorities and their houses of worship to continue with impunity, and also engaged in and tolerated hate speech and incitement to violence."

It pointed to comments by Home Minister Amit Shah, who notoriously referred to mostly Muslim migrants as "termites," and to a citizenship law that has triggered nationwide protests.

It also highlighted the revocation of the autonomy of Kashmir, which was India's only Muslim-majority state, and allegations that Delhi police turned a blind eye to mobs who attacked Muslim neighborhoods in February this year.

The Indian government, long irritated by the commission's comments, quickly rejected the report.

"Its biased and tendentious comments against India are not new. But on this occasion, its misrepresentation has reached new levels," foreign ministry spokesman Anurag Srivastava said.

"We regard it as an organization of particular concern and will treat it accordingly," he said in a statement.

The State Department designates nine "countries of particular concern" on religious freedom -- China, Eritrea, Iran, Myanmar, North Korea, Pakistan, Saudi Arabia, Tajikistan and Turkmenistan.

The commission asked that all nine countries remain on the list. In addition to India, it sought the inclusion of four more -- Nigeria, Russia, Syria and Vietnam.

Pakistan, India's historic rival, was added by the State Department in 2018 after years of appeals by the commission.

In its latest report, the commission said that Pakistan "continued to trend negatively," voicing alarm at forced conversions of Hindus and other minorities, abuse of blasphemy prosecutions and a ban on the Ahmadi sect calling itself Muslim.

India's citizenship law fast-tracks naturalization for minorities from neighbouring countries -- but not if they are Muslim.

Modi's government says it is not targeting Muslims but rather providing refuge to persecuted people and should be commended.

But critics consider it a watershed move by Modi to define the world's largest democracy as a Hindu nation and chip away at independent India's founding principle of secularism.

Tony Perkins, the commission's chair, called the law a "tipping point" and voiced concern about a registry in the northeastern state of Assam, under which 1.9 million people failed to produce documentation to prove that they were Indian citizens before 1971 when mostly Muslim migrants flowed in during Bangladesh's bloody war of independence.

"The intentions of the national leaders are to bring this about throughout the entire country," Perkins told an online news conference.

"You could potentially have 100 million people, mostly Muslims, left stateless because of their religion. That would be, obviously, an international issue," said Perkins, a Christian activist known for his opposition to gay rights who is close to President Donald Trump's administration.

Three of the nine commissioners dissented -- including another prominent Christian conservative, Gary Bauer, who voiced alarm about India's direction but said the ally could not be likened to non-democracies such as China.

"I am deeply concerned that this public denunciation risks exactly the opposite outcome than the one we all desire," Bauer said.

Trump, who called for a ban on Muslim immigration to the US when he ran for president, hailed Modi on a February visit to New Delhi.
