PM Modi blasts cow vigilantes, calls them 'anti-social'

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, May 13: Kannadigas in the United Arab Emirates (UAE) have sought additional flights to return to Karnataka during a video conference with Chief Minister B S Yediyurappa here on Tuesday.

Noting that most of the ex-pats in UAE were from the coastal region, they urged the state government to ensure that most of these flights land in the Mangalore International Airport.

Many Kannadigas in the UAE were left unemployed due to the lockdown. “Many of them do not have the means to return to Karnataka and the state government should aid them,” representatives of various Kannadiga ex-pat groups urged the CM.

Yediyurappa said that the government has made all arrangements to bring back the ex-pats, and assured to fulfil all their demands.

Belagavi, Jul 23: As many as 14 persons have been arrested following last night’s violence at Belagavi Institute of Medical Sciences (BIMS) - District Hospital.

Angered over the death of a Covid-19 patient, family members had turned violent and damaged the BIMS with stones and set an ambulance on fire alleging medical negligence. 

The 55-year-old male had been admitted to the hospital for treatment on July 19, for treatment of Severe Acute Respiratory Infection (SARI) and was positive for Covid-19 according to the report received on Wednesday. He died on Wednesday night while being shifted to Intensive Care Unit for treatment of respiratory problems.

Police rushed to the spot and brought the situation under control. Two persons were detained in the spot and 12 persons later. The matter is under investigation and the police have launched a manhunt to nab the other accused.

During the violence, a police personnel and five other hospital staff suffered injuries.

Meanwhile, prohibitory orders under Section 144 CrPC were imposed in the areas surrounding the hospital to prevent crowd gathering. 

Deputy Commissioner M G Hiremath visited BIMS on Wednesday night and held a meeting with the doctors and nurses treating the patients and those who were at the receiving end of the violence.

Hiremath said that he instilled confidence among the doctors and nurses and assured them that safety measures would be taken. Security arrangements will be made and prohibitory orders will be imposed. Presently entry of people has been banned, he said.

Police Commissioner Dr K Thiyagarajan said that cases will be filed against all those responsible for the violence. People whose vehicles have been damaged can also file complaints.
