35 Alva's students participate in South Zone Athletics meet

Pathnamthitta, Mar 10: A man under observation for suspected coronavirus infection at the isolation ward of the district hospital here fled, but was tracked and brought back within hours. The man was among those who had interacted with the three-member family who returned from Italy and have tested positive for the virus.

Pathnamthitta district collector PB Nooh said one person, who was under observation at the general hospital had escaped but was later tracked and brought back. "If even a single person under observation goes out, it is a threat. This is a public hazard".

The one excercise which the health authorities have to undertake on Tuesday is to see how many people had come incontact with this person after he left the hospital. There is need to isolate those people with whom he mayhave come into contact, the collector said "This is the timeto behave in a very socially responsible manner".

With six positive cases being reported, the state government has already warned that stringent action would be taken against those flouting the directions of the health department. Health Minister K K Shailaja has warned that those coming from COVID19 affected nations, should report to authorities on arrival in the state, failing which a case would be registered against them under the Public Health Act.

A 3-member family, which had come from Italy recently and had tested positive along with two of their relatives had not reported their arrival to the authorities, health officials said.

At least 733 people who had come in contact with them have been tracked, the collector said and have been placed under observation. While 18 have been admitted to isolation wards in hospital the remaining are under home surveillance.

A two-year-old child is among those under obsevation at the isolation ward, health department sources said. The tracking excercise would continue on Wednesday also.

Meanwhile, an awareness class was held for migrant workers at Pathnamthitta district this morning. However, no directions have been issued to workers fromother states to leave the state. "We are planning to give extra care to migrant workerswith labour officer visiting their colonies and as part of theawareness drive and speaking to them in a language theyunderstand," he said.

A three-year-old boy, who arrived with his parents in Kochi from Italy, tested positive on Monday, a day after three people, also with travel history from the European nation,were declared positive for the virus along with two of their relatives.

The Health Minister has said surveillance system would be stregthened with the support of ASHA workers, civic authorities and ward members and resident associations. Presently, 1,116 people are under surveillance in thestate for the corona virus, 967 in home quarantine and 149 in isolation wards of hospitals. Two 90-year-old relatives of the Pathnamthitta family, who tested positive, have been admitted to Kottayam medicalcollege hospital and their samples have been sent for testing, she said. "If they test positive for the virus, it would be highlyrisky", she had said.

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.

Kalaburgi, Jan 2: At least 10 students sustained injuries when a private bus carrying students of a school on an educational tour rammed into a tree today morning.

The mishap occurred when the students of Ayyappa School located in Chennaveera Nagar were going around the city in a bus during their tour.

The bus crashed into a tree near Venkatagiri Hotel on New Jewargi Road in the city.

A case has been registered at a traffic police station.
