Bengaluru, Jul 9: The total number of Covid-19 infections in Karnataka on Thursday breached the 30,000 mark as the state reported its biggest single-day spike of over 2,200 new cases and 17 related fatalities, taking the death toll to 486, the Health department said.

The day also saw a record 957 patients getting discharged after recovery, out of which 606 were from Bengaluru Urban.

Out of the 2,228 fresh cases reported on Thursday, a whopping 1,373 were from Bengaluru Urban alone.

The previous biggest single-day spike was recorded on July 8 with 2,062 cases.

As of July 9 evening, cumulatively 31,105 Covid-19 positive cases have been confirmed in the state, which includes 486 deaths and 12,833 discharges, the Health department said in its bulletin.

It said, out of 17,782 active cases, 17,325 patients are in isolation at designated hospitals and are stable, while 457 are in ICU.

"Death rate in Karnataka is 1.49 percent, while in Bengaluru is 1.28 percent, and our target is to bring it below 1 percent," Medical Education Minister K Sudhakar told reporters.

"The reason for spike in cases in Bengaluru and other places in recent days is because during the last four months of lockdown we had controlled it very well, but as we relaxed lockdown for economic activities we did not follow certain precautionary measures like distance among other things," he said.

The Minister also conceded that there were lapses on part of the government also in terms of tracing and tracking.

"It has to be improved especially in Bengaluru and we are taking steps in this regard."

Among the 17 dead seven were from Dharwad, two each from Hassan, Kalaburagi, Mysuru, and one each from Raichur, Uttara Kannada, Tumakuru and Davangere.

The deceased include 13 men and 4 women.

The dead are all either with a history of Severe Acute Respiratory Infection (SARI) or Influenza-like illness (ILI).

Out of 2,228 fresh cases today, contacts of the majority of the cases are still under tracing.

Among the districts where the new cases were reported, Bengaluru Urban accounted for 1,373, followed by Dakshina Kannada (167), Kalaburagi (85) and Dharwad (75).

Bengaluru urban district tops the list of positive cases, with a total of 13,882 infections, followed by Kalaburagi (1,901) and Dakshina Kannada 1,701.

Among discharges Bengaluru urban tops the list with total 2,834, followed by Kalabuagi (1,392) and Udupi (1,206).

A total of 7,79,209 samples were tested so far, out of which 20,028 were tested on Thursday alone.

So far 7,28,887 samples have been reported as negative, and of them 17,568 were reported negative today.

Davanagere, Jan 16: Congress leader D K Shivakumar on Thursday turned down all the recent media reports of him aspiring for the coveted Karnataka Pradesh Congress Committe (KPCC) president post.

Terming all the news, doing rounds, as baseless, Shivakumar said that he never made any attempt to become KPCC president. "All I want to do is work for my people and party", he asserted.

Referring to Chief Minister B S Yediyurappa's visit to Harihar's 'Our Lady of Health Minor Basilica' programme, Shivakumar said."I'm not concerned about what others are doing, everyone is free to take part in the programmes."

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.
