Muammar Gaddafi: Charming but cruel, recalls Kasargod doctor

Bengaluru, Apr 16: Former chief minister HD Kumaraswamy had said that his son Nikhil's marriage ceremony will take place at bride Revati's residence in Bengaluru, however, the wedding preparations are also going on in his farmhouse at Ramnagar.

This comes amid the lockdown in the country due to COVID-19 outbreak. The farmhouse is located at Kethaganahally, near Bidadi in Ramnagar.

Kumaraswamy has said the marriage will be simple and only his family members will attend and no one from outside would be invited.

Earlier Kumaraswamy has said that his son's marriage will take place on April 17 at bride house.

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, Mar 28: After a youth from Dakshina Kannada who tested positive for the deadly Covid-19 revealed that he had travelled by a bus, authorities have requested all his fellow passengers to visit their nearest district hospital. 

The 21-year-old man hailing from Belthangady taluk had flown from Dubai to Bengaluru on March 21 and on the same day travelled to Mangaluru by the KSRTC bus bearing registration number KA 19, F3329. 

As he was suffering from fever and cough he was admitted to Puttur government hospital on March 24. He was tested positive for the novel coronavirus on March 27.   

It is not yet know how many passengers were there on board the above mentioned bus which had departed Bengaluru at 4:30 p.m. on March 21. It is believed that most of the passengers who travelled by this bus are residents of Dakshina Kannada. 

Hence, the KSRTC authorities today requested all the passengers who travelled by this bus to visit their nearest district hospital for necessary checkup. The passengers also were urged to quarantine themselves for next couple of weeks.
