Engineering girl commits suicide after classmates harass her, remove her from WhatsApp group

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, Jan 20: The improvised explosive device (IED) recovered from a bag at Mangaluru airport was defused in an open field by the personnel of the bomb disposal squad on Monday. 

A short while ago, the Commissioner of Police in Mangaluru, PS Harsha, narrated the incident, along with the action taken by the security personnel.

"Today at approx 9 am a suspect dropped the baggage, containing plausible explosive substances, at the Mangaluru airport. It was spotted by the security personnel and then the bomb detection and disposal team was pressed into action," Harsha told reporters here.

"The area was cordoned off and then the suspected object was taken in a threat containment vehicle to a spot for defusing the explosive device. The local police have registered an FIR in this connection based on the complaints of CISF," he added.

The Commissioner said that three teams have been formed for "identification and apprehension of the accused."
He further said that the visuals of the suspect have been shared for his identification, and urged citizens of Mangaluru and around the nation to come forward and inform the police if they have any knowledge of the accused.

"Our teams have made some breakthrough and established few preliminary facts and I am assured we will be able to trace out the execution plan of the act of sabotage," he added.

Mangaluru, May 22: An elderly cardiac patient from Dakshina Kannada, who was stranded in Saudi Arabia due to covid-19 lock-down, has finally reached his homeland thanks to the timely intervention by Humanity Forum Jubail and Indian Social Forum.

The elderly man hailing from Kadaba area of Dakshina Kannada was admitted to a hospital in Madinah. However, his condition continued to worsen due to lack of proper treatment. The efforts by his family members to bring him back home had not yielded results.

Meanwhile, one of the relatives of the patient, Ansari Suratkal, who happens to be a DKSC activist, brought the issue to the notice of the Karnataka unit of the Indian Social Forum in Dammam. ISF contacted Humanity Forum president Zakariya Jokatte, who helped the patient to speak directly union minister D V Sadananda Gowda in a video conference organised by coastaldigest.com.

Humanity Forum also persuaded the Indian Embassy to allow the stranded cardiac patient to fly back to India through Dammam-Bengaluru repatriation flight on May 20. 

However, it was not easy for the patient to travel from Madinah to Dammam International Airport due to lock-down and curfew. ISF not only obtained travel permission for him but also arranged vehicle. Jeddah and Riyadh units of ISF helped in obtaining permission letter in their respective places in spite of travel ban imposed by the police. Madinah unit of ISF arranged vehicle for transportation. Zakariya Jokatte bore the air ticket and other expenses of the patient.
