Among those discharged today, 13 are in Davangere, 12 in Dakshina Kannada, nine each in Yadagiri and Vijayapura, five in Gadag, three in Belagavi, one each in Mysuru and Bagalkote.

Two are severe acute respiratory infection cases.

There were, however, no coronavirus related deaths in the state today, the minister said.

Kumar said the government has issued another circular making changes in the quarantine rules.

"A person who has completed seven days of institutional quarantine and is asymptomatic can be permitted for home quarantine without a COVID test, subject to undergoing medical check-up," the minister said.

According to the circular, all elderly people of above 60 years of age and those with comorbidities such as diabetes, hypertension, asthma, heart ailment and renal diseases, are required to be clinically evaluated diligently prior to shifting them to home quarantine.

Such people will be under mandatory home quarantine for seven days, the circular read.

Udupi, Mar 14: Amidst growing Coronavirus scare, a youth with suspected Coronavirus symptoms was admitted to Udupi District Hospital here, District Health and Family Welfare Officer Sudhir Chandrachud said.

According to him, A 37-year-old youth, a native of Shirwa, who works in a Japanese ship and was onboard a Japanese vessel that was recently blocked due to the coronavirus. However, he was left out on its way to Dubai, where he was diagnosed with coronavirus infection and he returned to his native.

However, he did not show any of the primary symptoms of coronavirus, such as cough, cold, fever, but he was suffering from diarrhea and abdominal pain with slight respiratory problems following which he has been admitted to an isolated ward in the district hospital here on Friday evening.

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.
