Polls: Mandya DC gets death threat, files police plaint

Bengaluru, Jul 9: Bringing to the fore the dangers frontline workers face in combating the deadly coronavirus, 395 policemen have tested positive for the infection since the outbreak of the pandemic in Bengaluru. This includes five deaths, Inspector General of Police and Additional Commissioner of Police (Administration) Hemant Nimbalkar told media persons.

He said as of Thursday, 190 have been cured while 200 are under treatment. Twenty police stations have been sealed, he added.

He claimed the Bengaluru police has suffered the most compared to any department, organisation or institution because the force is deployed in the field and dealing with the situation.

The infection among police is highest despite training being given to them on how to protect themselves from the coronavirus.

According to him, every morning duty charter is given to the police personnel where they are told how to avoid getting the infection and handle the situation if they find symptoms of coronavirus.

"Despite taking all the precautions, infection in our department is high because we are the ones who are on the road.

We are meeting hundreds of people whom we don't know, whether they are Covid infected or not," Nimbalkar said.

Along with the policemen, their families too are at risk of contracting the virus.

An assistant sub-inspector at VV Puram police station was the first casualty in the Bengaluru police on June 13.

A heart patient, who was on leave due to ill health, he collapsed at home and died.

Jan 30: One positive case of novel coronavirus has been found in Kerala. The student was studying at Wuhan University in China. The patient is stable and is being closely monitored.

This is the first case of coronavirus that has been reported in India.

Until now, there have only been many suspected cases across the country. A total of eight patients, five of them in Mumbai, are under observation in Maharashtra for suspected coronavirus infection. Six patients were already under observation and two more people, who complained of cough and mild fever, symptoms similar to the coronavirus, were put under medical watch on Tuesday evening.

One suspected case each has been reported in Rajasthan and Chandigarh.

Novel coronavirus (nCoV) is a large family of viruses that causes illnesses ranging from the common cold to acute respiratory syndromes. However, the virus that has so far killed 170 people and affected 7,000 in China is a novel strain and not seen before.

It has emerged from a seafood and animal market in Wuhan city and is suspected to have spread to as far as the United States.

According to the World Health Organisation, the common symptoms of the novel coronavirus strain include respiratory symptoms such as fever, cough, shortness of breath and breathing difficulties.

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.
