KSOGA holds its 22nd conference

Kochi, Mar 9: A three-year old child has tested positive for the novel coronavirus, officials said in Kochi on Monday.

The child and its parents who had reached the Cochin International Airport Limited at 6 AM on March 7 from Italy were subjected to thermal screening at the universal surveillance system established, officials said.

Detecting symptoms of coronavirus in the child, they were immediately referred to the isolation ward of the Kalamassery Medical College Hospital, they said. The samples of the child sent for examination at the NiV lab at Alappuzha have tested positive for Coronavirus, they said.

The samples of the parents have also been sent for lab test, the officials added.

Five fresh coronavirus cases, including three who evaded screening on return from Italy, were reported in Kerala, prompting the government on Sunday to sound a renewed alert and warn action against those hiding travel history to affected nations.

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.

Bengaluru, Jun 27: Marijuana or ganja as it is known locally, has emerged as the most peddled and seized drug in Karnataka in the first six months of 2020, a police officer has said, commemorating the International Day Against Drug Abuse and Illicit Trafficking.

"As many as 510 ganja cases have been registered, leading to the seizure of 312 kg of ganja in 2020," Central Crime Branch (CCB) Deputy Commissioner of Police Kuldeep Jain told media perrsons on Friday.

Cases and seizures of other drugs paled in comparison to Marijuana. Only one case each has been registered on Brown Sugar, Opium and other drug forms.

Hashish was the only other seized narcotic which weighed more than a kg at 17 kg, rest all were under a kg.

Other banned substances included charas, cocaine and MDMA.

Police also seized 91 papers of LSD and 550 tablets belonging to the Yaba, Restyl, Anxit and Nitrosun category of drugs.

Similarly, 781 Indians and 14 foreigners have been arrested in the drugs cases.

Karnataka Home Minister Basavaraj Bommai, Director General of Police Praveen Sood and Bengaluru Police Commissioner Bhaskar Rao were among the officials who commemorated the event which recognised police staff who cracked drug cases.

"Bommai reaffirmed the pledge to fight against drugs and continue the policy of zero tolerance (of drug abuse)," Joint Commissioner of Police Sandeep Patil said.

Police showcased the seized haul of drugs to Bommai in the past one year, and the minister later rewarded the policemen involved in cracking the drugs cases in Karnataka.

Bommai and the police officials took a pledge to fight drugs on the occasion.

"The Karnataka police has been taking strict action against the drug peddlers while at the same time creating awareness among youth," added JCP Sandeep Patil.

Police also roped in celebrities such as Milana Nagaraj, Darling Krishna and former cricketer Anil Kumble to send across a social message to give up drugs.
