Mangaluru, July 8: Dakshina Kannada on Wednesday recorded its highest single-day spike in Covid-19 cases with 183 cases reported in the district, while Udupi reported 31 new cases.

DK also recorded two more fatalities – both patients with co-morbid conditions — taking the total death toll in the district to 28. Udupi has recorded three Covid-19 deaths.

The fresh spike saw total positive cases in DK shoot up to 1,542 and active cases to 819. As many as 12 patients were discharged from hospital on Wednesday. The positivity rate in the district now stands at 0.07 %. Health authorities as on date have received 22,181 samples and 20,153 out of 21,695 samples tested have turned out negative.

MLA’s gunman tests positive

The gunman assigned to former minister U T Khader tested positive on Wednesday and three others who were with him in the escort vehicle have been quarantined, said city police commissioner Vikash Kumar Vikash. A section of police commissioner’s office was shut for sanitisation as per protocol after staff working there were treated as primary contacts. The office per se has not been sealed contrary to ‘reports’ doing rounds in social media, he said.

Deputy commissioner Sindhu B Rupesh said the district reported two deaths — one late on Tuesday and the other during the day. The victims are a 57-year-old man and 32-year-old youth. Two of the 183 cases were secondary contacts, 25 were cases of influenza like illness, four cases of SARI, one a case of inter district travel, two with interstate travel, five with international travel history, 22 random samples and five pre-surgery samples.

Udupi district recorded 31 new cases taking the total positive cases recorded as on date to 1,421. Discharge of 1,189 patients meant that Udupi has 229 active cases.

Meanwhile, Kota Shrinivas Poojari, minister for fisheries on Wednesday inaugurated the Covid-19 lab at district hospital in Udupi. Karkala MLA Sunil Kumar inaugurated ambulance monitoring system to ensure expeditious transfer of infected patients to designated treatment centres.

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 3: Mangaluru police arrested another person on charge of spreading communal hatred through messages. The accused have been identified as Abubakkar Siddique (48).
