Bengaluru, Apr 23: Nine new COVID-19 positive cases have been reported in Karnataka in the last 24 hours.

Out of these nine coronavirus positive cases, five have been reported from Kalaburagi and two each from Mysuru and Bengaluru.

According to the government of Karnataka, the total number of positive cases in the State now stands at 427 including 131 cured or discharged cases and 17 deaths.

The total number of positive coronavirus cases across the country are 19,984, including 15,474 active cases of the virus. So far, 3,869 patients have either been cured or discharged while 640 deaths have been recorded in the country, as per data provided by the Union Ministry of Health and Family Welfare.

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, Jan 12: Sudarshan Moodbidri and Robin Devaiah were today unanimous elected presidents of Dakshina Kannada and Kodagu district units of Bharatiya Janata Party.

Karnataka BJP vice-president Nirmal Kumar Surana oversaw the election process of the two district units at the BJP’s party office here.

While Sanjeeva Matandoor, Puttur MLA and incumbent president of DK unit of the party welcomed his successor Sudarshan, it was the turn of BB Bharatheesh, president of Kodagu unit to welcome Robin.

K Uday Kumar Shetty, DK district election officer and Ravi Kalappa, Kodagu district assistant election officer conducted the election under the supervision of Surana in the presence of MLAs of the party from respective districts.

Sudarshan started out his career as taluk and then district convener of Bajrang Dal before taking up responsibility as seva pramukh of Vishwa Hindu Parishad.

He formally joined the BJP as general secretary of Mulki-Moodbidri assembly unit of the party, moved on as convener of training cell of the party and was the general secretary of the district unit of the party before his elevation. A B.Com student of Dhavala College, Moodbidri, he is 44.

Robin, 50, who started out as a RSS volunteer as a student, too is incumbent general secretary of the Kodagu unit. Having been a member of ABVP for 8-years, he joined BJP formally in 1996 through Yuva Morcha and was its district treasurer, national executive member and state general secretary.

A product of Field Marshal K M Cariappa College, Kodagu, he served two terms as general secretary of the district unit prior to his elevation.
