Thiruvananthapuram, Feb 6: The Kerala government on Wednesday said three foreign nationals were among the 2,528 people under observation in the state for the novel coronavirus infection and no new cases have been reported.

At least 93 people with minor symptoms of the virus have been lodged in isolation wards of various hospitals, state Health Minister KK Shailaja told reporters in Thiruvananthapuram.

India's three positive cases for the virus has been from the state's three districts of Thrissur, Alappuzha and Kasaragod.

All the three are students of China's Wuhan university, the epicentre of the virus.

"No new cases of coronavirus has been detected in the state today. At least 2,435 are under observation at home while 93 are in isolation wards at various hospital across the state," Mr Shailaja said.

The minister also said two foreigners have been quarantined in Ernakulam district and one foreign national at Thiruvananthapuram.

"The foreigner in Thiruvananthapuram has been kept at general hospital but not because he was showing symptoms but for observation as he travelled from China," an official said.

The health status of the three patients, who had tested positive for the virus, "remains satisfactory", the minister said.

After three cases were reported, the Left Democratic Front (LDF) government had declared the epidemic as a "state calamity" on Monday.

The health department has issued advisories to the education, tourism and the animal husbandry departments on taking precautions.

"The students, teachers, other staff members residing with families of Wuhan/China returnees who are already in home isolation should not attend classes...," an advisory issued to the education department read.

Rajan Khobragade, Principal Secretary (Health), said the health department has directed the District collectors to hold a meeting with the religious leaders of the district to create awareness during prayer meetings.

"We have directed district collectors to meet religious leaders and talk to them about the seriousness of the situation and create awareness among them and their followers on how to contain the spread of virus," the minister said.

Mr Shailaja also said the department got messages from some Kerala students studying in China, who returned to the state after the virus outbreak, that their Universities had asked them to return and attend classes.

"We have got some messages from the students that they were being recalled by the universities in China. We discussed the matter and it was decided that the centre will contact such universities and convey the message that it was not possible to send the students back to China until the epidemic was under control," the minister said.

Mr Shailaja also said even though there were no positive cases for the second consecutive day on Wednesday, the state needs to remain vigilant and reiterated the 28 days quarantine period for those returning from China.

Of the 2,528 people under observation, the maximum number is from Malappuram (383), followed by Ernakulam (333), Kozhikode (306) and Thrissur (241).

Thiruvananthapuram, Apr 27: Kerala Chief Minister Pinarayi Vijayan on Sunday said the issue of return of Non-Resident Keralites (NRKs) to the state has been taken up with the Centre and the state government is awaiting a favourable response.

Vijayan said this in a meeting with Non-Resident Keralites over steps taken by the state government for those wishing to return to the state from foreign countries.

The Chief Minister announced that the Department of Non-Resident Keralites Affairs has opened online registration for such NRKs.

"Those returning should undergo screening at airports. All those returning should undergo mandatory home quarantine for 14 days.

Arrangements of isolation wards will be provided for those unable to go home," said Vijayan.

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.
