Will you cleanse every place I visit, Prakash Rai to BJP

Bengaluru, Mar 24: Underlining the seriousness of the coronavirus, which is spreading like wildfire in Karnataka, renowned Heart Surgeon and founder of Narayana Hrudayalaya Dr Devi Shetty on Tuesday predicted that Karnataka alone will have more than 80,000 people affected with the dreaded killer disease COVID-19 if people fail to protect themselves.

He urged the people to cooperate with the Government in preventing its further spread and immediately treat those who are affected.

Dr Shetty, urging the people to remain indoors and not to venture out, said those who are affected should not come out and remain in isolation even in their houses and take all precautions advised by doctors.

He said if 80,000 people in the state were affected, more than 20,000 need to be admitted to Hospital for treatment.

"More than 2000 affected need to be kept under ventilation and it requires more infrastructure in the hospitals," he said.

Bengaluru, Mar 2: The Opposition Congress and the JD(S) members protested in the Karnataka Legislative Assembly on Monday over the BJP leader Basavaraj Patil Yatnal's alleged derogatory remark against veteran freedom fighter H S Doreswamy.

Opposition Leader in the Assembly and former Chief Minister Siddaramaiah, raised the issue, immediately after the obituary reference of sudden demise of former Minister C Chanigappa, and sought permission from the Speaker to raise the issue of Yatnal's outburst in the House stating that the matter of hurling defamatory remark against Gandhian Doreswamy, by Mr Yatnal, was very much serious. However, the treasury bench members protested and urged the Speaker not to allow the matter to discuss as the issue was not in the agenda.

The Speaker, Vishveshwar Hegde Kageri, promised the Congress leader about permitting the issue after the House adopts resolution on the thanksgiving motion for the Governor's address of the joint House recently and asked Chief Minister B S Yediyurappa to continue his reply to the Governor's address.

The opposition Congress and the JD(S) members, protesting the Speaker's action, trooped into the well of the house and raised slogans against the BJP government.

The Chief Minister continued his reply amidst the din before the Speaker adjourned the House for 30 minutes after the House adopted the thanksgiving motion to the Governor's Address.

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.
