Seoul, March 11 (IANS) Jae-yong, the imprisoned de facto leader of Samsung Group, is under investigation over an allegation that he took anesthesia drug propofol shots illegally, police said on Thursday.Propofol is a highly regulated drug in South Korea that the country's Ministry of Food and Drug Safety issued standards to prevent its misuse and abuse.The ministry issued a notice last September to set standards for the use of narcotic drugs propofol and zolpidem, saying propofol is a "psychotropic drug used to induce and maintain the general anesthetic state."The Gyeonggi Nambu Police Agency said they were looking into the accusation made against Lee, vice chairman of Samsung Electronics, that he illegally used the anesthesia drug at a plastic surgery clinic in Seoul last year, but refused to provide further details on the ongoing case, reports Yonhap news agency.The police are said to have visited Lee, who is imprisoned in the Seoul Detention Center in Uiwang, south of the capital, last month to take a hair sample from him for drug testing.Lee is currently serving a two-and-a-half-year prison term for bribing impeached former President Park Geun-hye and her longtime friend Choi Soon-sil to win government support for a smooth father-to-son transfer of managerial power at Samsung.Samsung said that Lee only took propofol shots for medical purposes and that the police have not corroborated the allegation against him, reports Yonhap news agency.Early last year, a similar accusation was filed against Lee with the Anti-Corruption and Civil Rights Commission that he regularly used propofol at another plastic surgery clinic in Seoul.The case has been referred to the Supreme Prosecutors Office.Lee also denied the allegation at that time and requested the case to be reviewed by an independent committee consisting of outside experts to see whether the prosecution's investigation is legitimate.--IANSwh/na
Toronto - Researchers have found that exposure to general anesthesia during surgery may not contribute to an increased risk of Alzheimer's disease or dementia.
According to the study, published in the Journal of the American Geriatrics Society, cognitive changes are commonly observed in older adults following surgical procedures.
There are concerns that exposure to general anesthesia during surgery may raise the risk of Alzheimer's disease.
"Many older adults experience changes in their cognition immediately following surgery and wonder what role the type of anesthetic might have played in these changes," said senior author Dallas P Seitz from the University of Calgary in Canada.
"Our study provides evidence that anesthetic technique used during elective surgeries, general anesthesia or regional anesthesia is not associated with a long-term risk of developing dementia," Seitz added.
To investigate, researchers compared exposure to general anesthesia versus regional anesthesia during elective surgery, looking for potential links to the development of dementia.
The study included 7,499 matched pairs of community-dwelling individuals aged 66 years or older who underwent surgery between 2007 and 2011 and were followed for up to five years.
The investigators found no difference in risk of being diagnosed with dementia for individuals who received general anesthesia when compared with those who received regional anesthesia.
"There was also no association between anesthesia and dementia in most subgroup and sensitivity analyses," the study authors wrote. (Agency)
