'Parents post their kids’ photos online despite knowing it may cause harms'

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, Jul 26: Rubbishing reports about cancellation of institutional quarantine for international passengers in Mangaluru, local health authorities have clarified that 14 day isolation including first seven day institutional quarantine must for international passengers. 

For past couple of days rumours were doing rounds on social media that the government has done away with quarantine for international passengers. A few Mangaluru-based news portals also had published it as news without quoting any reliable sources. 

Meanwhile, district health officer in his clarification message said that neither Karnataka government nor Dakshina Kannada district administrant has revised the quarantine norms for international passengers. 

“Those who arrive from overseas must remain in isolation for 14 days. Out of this, seven days have to be spent in institutional quarantine (in hotel or lodge). During this period, the throat swab sample of the person will be sent for covid-19 testing. If the report is negative, then they will be sent to home quarantine for another seven days."

He said that concession in terms of number of days has only been given for people with other health conditions, children and the elderly. "For children below 10 years, pregnant women, elderly above the age of 60 years and other with other ailments, the throat swab will be collected on the second day of institutional quarantine. If the report turns negative, they will be sent to home quarantine for 14 days."

Veteran journalist P. Sainath has said that the nation is in a crisis. And this crisis is not limited to just the rural area. It has become a national crisis at various areas such as agriculture, education, economy, job creation etc.

He was delivering the endowment lecture on the topic ‘Indian democracy at the post-liberalization and post-truth era’ at Media Manthan 2020 organized by the PG department of journalism and mass communication at St Aloysius College (Autonomous). 

Mr Sainath said that the many policies adopted in the 90s led to India becoming unusually unequal. Referring to the speech Ambedkar had made at the Constituent Assembly while handing over the draft of the Constitution, Mr Sainath said, “Ambedkar had warned about the weakness of Indian democracy that liberty without equality allows the supremacy of a few over the multitude. Liberty, equality and fraternity must be kept together as we cannot have one without the other.” 

Mr Sainath stated that the agrarian crisis was no longer about the loss of productivity, employment or about farmer suicide; it was a societal, civilizational crisis. Commenting on the lopsided policies such as cow-slaughter ban, he explained how cow slaughter ban had adversely affected many industries due to their interdependency. While Muslims who slaughtered cows were rendered helpless, the cattle traders who were mostly OBCs lost their earnings as the cattle prices crashed. An important industry like Kolhapur sandals industry in Maharashtra went bankrupt as a result of the cow slaughter ban in Maharashtra. He said the policymakers had no idea how the rural industries were interconnected. Demonetisation too devastated the rural economy as 98 percent of rural transactions happen through cash. 

Mr Sainath also spoke about the crisis of inequality which affects the Dalits and the Adivasis far more than anyone else as 90 percent of the rural households take home less than Rs 10,000/- per month. “Women are yet another group whose labour is never counted in the gross domestic product. Women and girls globally do unpaid work which amounts to about 12.5 billion working hours per year. Monetarily speaking, this is worth 10.8 trillion dollars,” Mr Sainath added. 

Speaking about the crisis of jobs Mr Sainath said that major companies were laying off employees just to create more profits for the investors and the adoption of artificial intelligence in the industry would further destroy millions of jobs.

Rector of St Aloysius College Institutions Fr Dionysius Vaz SJ, Principal Dr (Fr) Praveen Martis SJ, HOD of Journalism and Mass Communication department Dr (Fr) Melwyn Pinto SJ were present.

‘Veerappan and Vijay Mallya’s business models are interesting!’

Addressing the gathering during his endowment lecture on Friday, Mr Sainath made an interesting comment on the so called ‘revenue model’. “Whenever I visit IIMs and IITs for lectures on my PARI project, the students there ask me what my revenue model for my project is. I tell them that I do not have a revenue model. In fact, journalism does not begin with a revenue model. Gandhiji, Ambedkar, Bhagat Singh were all great journalists. But they did not have a revenue model,” Mr Sainath said.

On a lighter note, he said that the best revenue model that he liked was that of forest brigand Veerappan and liquor baron Vijay Mallya. “Veerappan ruled the forest for forty years and from the top ministers to the villagers he could dictate terms and liver royally. Similarly, Mallya’s revenue model was to steal the banks and run away abroad and live like a king,” Mr Sainath added.

Journalism is not and can never be a business. It is a calling, he opined. While newspaper can be a business, television can be a business, journalism per se cannot be reduced to a business. “Unfortunately today, journalists are recruited on a contract basis and they have no bargaining power; and there are no unions to fight for their cause. Hence, they are at the mercy of the corporate media houses for their survival and are made to write stories that cannot be called journalism,” Mr Sainath said.

Answering a question as to the pressures he faced as a journalist, he said that external pressures from the government or others could be very well handled. It is the internal pressures from once own media house that journalists find it difficult to manage.
