CAB aims to protect 1.5 cr Hindus: Nalin Kumar Kateel

Bhatkal, Mar 30: Uttara Kannada district administration has decided to shift all those Bhatkal residents who have returned from abroad after March 15 to quarantine facilities in Bhatkal town to avoid further family contacts, Deputy Commissioner of Uttara Kannada K Harish Kumar said on Monday.

“All primary contacts identified are already in government quarantine facilities,” he said in a communique.

All people must cooperate to maintain social distancing to avoid further spread of COVID-19, he added.

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.

The Indian government has advised expats in the UAE and the Gulf against travel till flight curbs to their home country are lifted. This follows the clamour from some quarters for special repatriation flights to India.

A senior Indian External Affairs Ministry (foreign ministry) official said Indian citizens are safe in the countries they reside in. Prime Minister Narendra Modi had spoken to leaders of Gulf countries who assured him of their welfare, the Indian foreign ministry said. Meanwhile, the Minister of State for External Affairs, V Muraleedharan,, according to a Malayalam news report, also ruled out special flights.

Responding to a question from Khaleej Times on blue-collar workers' angst following job losses, Vikas Swarup, Secretary West in the foreign ministry said, "Insofar as repatriation is concerned, as you are aware, government has advised against all travel, and Indians have been told to stay where they are, As and when the (21-day) lockdown is lifted, and normal civil aviation resumes, Indians wishing to come back will be able to do so."

According to the latest data from the Indian foreign affairs ministry, there are 1,400 cases of Covid-19 infections among Indian expats in the Gulf region.

Swarup said infected Indians are being treated and kept in isolation in the UAE and Gulf. "Our missions have established contact with all the community leaders and the situation is under control," he said.

Cargo flights operating as usual  

Cargo flights carrying fruits and vegetables from India to the Gulf have not been disrupted and would continue as usual, the diplomat said. "We are also helping with medicines based on the requests of Gulf countries," he said.

Eight million India expats live in the Gulf, including close to three million in the UAE. They account for more than 60 per cent of remittances to their home country.

India's long lockdown of 21 says ends next Tuesday. Indications are that it could be extended. Some states like Orissa have already stretched it till the end of the month and others are expected to follow suit.

The government believes that the disease is now concentrated in 75 districts, and the focus should be on these areas to manage and contain the virus.
