ASHAs hold protest across Karnataka demanding PPE kits, salary hike

Mangaluru, Apr 30: Yet another case of covid-19 reported in the coastal city of Mangaluru today.  

The Dakshina Kannada district administration confirmed that a 58-year-old woman hailing from Boluru area in the city was tested positive for the coronavirus.

The woman was undergoing treatment in First Neuro Hospital at Padil where a woman from Bantwal (identified as P-501), who died of coronavirus had undegone treatment before being shifted to Wenclock. 

With this, total number of positive cases in Dakshina Kannada district has gone up to 22.

Bengaluru, June 21: An assistant sub-inspector of police who was undergoing treatment for COVID-19 infection in city-based Victoria hospital passed away on the intervening night of Saturday and Sunday as he did not respond to the treatment for coronavirus.

The 59-year-old ASI was attached to the Wilson Garden traffic police station in Bengaluru. He tested positive for coronavirus on June 18 and was rushed to the COVID ward in Victoria hospital on June 19. He had fever for the last four days. His wife and two children have been quarantined. According to the police, the station has not yet been sealed down and no policemen have been quarantined.

The Wilson Garden ASI is the third Bengaluru police personnel to die of COVID-19 in the last one week. Earlier, an ASI from the VV Puram traffic police station had died undergoing treatment. On Saturday morning, a head constable from the Kalasipalya police station who was admitted at Victoria hospital passed away. The series of deaths in the police department has created fear among other policemen across the city.

One the other hand, dozens of policemen were tested positive in different parts of Karnataka today including 21 from two police stations of Bengaluru. 

Around 15 policemen from the Kalasipalya police station and five policemen from the Ashok Nagar traffic police station tested positive for coronavirus on Sunday.

In Kalasipalya, three ASIs, head constables and police constables have tested positive. In Ashok Nagar traffic police station, a probationary sub-inspector, an ASI, two police constables and a lady constable tested positive for the virus.

One more police constable working in Bandepalya police station also tested positive. Seven policemen who were in his primary contacts have been quarantined. BBMP officials have begun the process of fumigating the station premises and its surroundings.

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.
