SDPI slams police, govt for ban on Zakir Naik; denounces double standard

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.

Abu Dhabi, Feb 17: NMC Health Plc, a hospital operator targeted by short-seller Muddy Waters, said founder Bavaguthu Raghuram Shetty resigned amid investor concern he faced a margin call and misrepresented his stake.

The board asked for Co-Chairman Shetty’s resignation and it takes effect immediately, according to a person with knowledge of the situation. NMC has lost four board members since Friday, including Vice Chairman Khaleefa Butti, whose holdings are also being probed. The stock, the worst performer on the FTSE-100 Index this year, fell as much as 9.2 percent Monday morning and then rebounded.

“The resignation of senior board members should be viewed positively,” said Abdulla Nahlawi, an analyst at Rasmala Investment Bank in Dubai. “The credibility of the current board has been jeopardized with the unfolding of the recent events.”

NMC shares lost almost half their value the first week of February on speculation the company’s main investors faced a margin call, in which banks seize shares pledged as collateral. NMC said Friday that First Abu Dhabi Bank and Al Salam Bank Bahrain obtained 20 million shares in the company from BRS International Holding, an investment vehicle of NMC’s top shareholders. The banks sold more than 8 million of those shares as “enforcement of security,” NMC said.

NMC operates the largest medical network in the United Arab Emirates and in 2012 became the first Abu Dhabi company to list in London. The shares started teetering in mid-December when Muddy Waters alleged that NMC manipulated its balance sheet and inflated the prices of companies it acquired.

Shetty, 77, was born in India and founded NMC in the 1970s after moving to Abu Dhabi. His spokesman said a legal review of the situation is ongoing and declined further comment.

Chief Investment Officer Hani Buttikhi and board member Abdulrahman Basaddiq also stepped down because they were appointees of Shetty and Butti, NMC said, adding that they had no knowledge of the share transfers.

Questions remain over the role of Shetty’s family at the company. His wife and son-in-law both hold roles in senior management.

Almost 10 per cent of NMC’s freely traded shares are shorted, according to Markit Securities data. In mid-December about a third of them were.

Last week GKSD Investment, an investment company backed by hospital investors, said it’s studying a possible offer for NMC. Under U.K. takeover rules, it has until March 9 to make a bid.

NMC has said Muddy Waters’s claims are false and the company hired former FBI Director Louis Freeh to conduct an independent review. The review is due to be completed before the company issues its financial results in March, the person said.

NMC said Mark Tompkins will continue as the company’s sole chairman.
