Bharat bandh evokes good response in Manglauru, Udupi

Mangaluru, Mar 29: The test report of the man from Uppoor in Udupi district, who committed suicide fearing he had contracted coronavirus infection, has returned negative for the virus.

Health department officials in Udupi said the post- mortem test report had shown that he did not have the virus infection and asked the people in the area not to panic.

Gopalakrishna Madivala (56), had hanged himself on Wednesday suspecting he had the disease, leaving a death note to family members asking them to stay safe.

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.

The Central Board of Secondary Education (CBSE) has rationalised by up to 30 per cent the syllabus for classes 9 to 12 for the academic year 2020-21 to reduce course load on students amid the COVID-19 crisis, Union HRD Minister Ramesh Pokhriyal 'Nishank' announced on Tuesday.

The curriculum has been rationalised while retaining the core elements, the Human Resource Development said.

Among the chapters dropped after the rationalisation exercise are lessons on democracy and diversity, demonetisation, nationalism, secularism, India's relations with its neighbours and growth of local governments in India, among others.

"Looking at the extraordinary situation prevailing in the country and the world, CBSE was advised to revise the curriculum and reduce course load for the students of classes 9 to 12.

"To aid the decision, a few weeks back I also invited suggestions from all educationists on the reduction of syllabus for students and I am glad to share that we received more than 1.5K suggestions. Thank you, everyone, for the overwhelming response," Nishank tweeted.

"Considering the importance of learning achievement, it has been decided to rationalise syllabus up to 30 per cent by retaining the core concepts," he added.

The Union minister said the changes made in the syllabi have been finalised by the respective course committees with the approval of the curriculum committee and the Governing Body of the Board.

"The heads of schools and teachers have been advised by the board to ensure that the topics that have been reduced are also explained to the students to the extent required to connect different topics. However, the reduced syllabus will not be part of the topics for internal assessment and year-end board examination.

"Alternative academic calendar and inputs from the NCERT on transacting the curriculum using different strategies shall also be part of the teaching pedagogy in the affiliated schools," a senior official of the HRD ministry said.

For classes 1 to 8, the National Council of Education Research and Training (NCERT) has already notified an alternative calendar and learning outcomes.

According to the updated curriculum, among the chapters deleted from class 10 syllabus are-- democracy and diversity, gender, religion and caste, popular struggles and movement, challenges to democracy

For class 11, the deleted portions included chapters on federalism, citizenship, nationalism, secularism, growth of local governments in India.

Similarly, class 12 students will not be required to study chapters on India's relations with its neighbours, changing nature of India's economic development, social movements in India and demonetisation, among others.

Universities and schools across the country have been closed since March 16 when the central government announced a nationwide classroom shutdown as one of the measures to contain the COVID-19 outbreak.

A nationwide lockdown was announced on March 24, which came into effect the next day. While the government has eased several restrictions, schools and colleges continue to remain closed.
