Congress bites dust in Udupi dist; BJP sweeps all five constituencies

Davanagere, Apr 26: Amid the national lockdown imposed by the Centre to check the spread of coronavirus, social distancing norms were flouted as BJP MLA from Honnali -- MP Renukacharya -- held a meeting of ASHA workers on Thursday.

The workers were present in large numbers and no distance of at least one metre between the workers was maintained during the meeting.

However, the workers were seen wearing masks at the meeting but violating the norms of social distancing.

Social distancing is one of the measures that can help people avoid contracting the highly contagious coronavirus.

According to the Union Ministry of Health and Family Welfare, Karnataka has a total of 489 positive COVID-19 cases of which, 153 patients have recovered and 18 patients have died due to the deadly virus.

Bengaluru, May 1: Chief Minister BS Yediyurappa on the occasion of International Labour Day has appealed to migrant workers in the state to stay back and co-operate with it in resuming economic activities once the Central government issues further directions.

"It is my sincere request to all the migrant workers to stay back in the state and co-operate with us to resume the economic activities once we receive directions from Union Government," Yediyurappa said in a release issued by the CMO.

"COVID-19 situation in India is much better than other countries because of people's cooperation.

We intend to resume economic activities soon. The government has already held a meeting with representatives of associations of commerce and industry in this regard. The government has also appealed to the employers to protect the interest of their workers and pay salaries," he added.

The ongoing nationwide lockdown, imposed to contain the coronavirus spread, is scheduled to end on May 3.

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.
