According to a research published in the journal, Lancet Diabetes and Endocrinology, there is a very low risk of developing dementia among the middle aged obese people.

The research based on medical records of nearly two million people contradicts previous researches and states that there is a risk of getting diagnosed with dementia due to increase in obesity.

Professor Stuart Pocock from the London School of Hygiene & Tropical Medicine said “Our results also open up an intriguing new avenue in the search for protective factors for dementia.”

“If we can understand why people with a high BMI (body mass index) have a reduced risk of dementia, it’s possible that further down the line, researchers might be able to use these insights to develop new treatments for dementia,” Pocock added.

A study found out that around two million people with an average age of 55 years and an average of BMI of 26.2 kg/m2 are classed as overweight. And, during a nine years follow up around fifty thousand people were diagnosed with dementia.

People with BMI greater than 40 kg/m2, 29 percent of people are diagnosed with dementia than people in the normal weight.

Middle aged people who are underweight have a 34% higher risk of being diagnosed with dementia than those of a healthy weight.

“The reasons why a high BMI might be associated with a reduced risk of dementia are not clear, and further work is needed to understand why this might be the case. Many different issues related to diet, exercise, frailty, genetic factors, and weight change could play a part ” said, the study’s lead author Nawab Qizilbash.

New York City’s Mandatory Measles Vaccination Order Stands Still

The health department's lawyers argued that quarantining was ineffective because people carrying the virus can be contagious before symptoms appear.

Brooklyn judge on Thursday ruled against a group of parents who challenged New York City’s recently imposed mandatory measles vaccination order, rejecting their arguments that the city’s public health authority exceeded its authority.

In a six-page decision rendered hours after a hearing on the matter, Judge Lawrence Knipel denied the parents’ petition seeking to lift the vaccination order, imposed last week to stem the worst measles outbreak to hit the city since 1991.

The judge sided with municipal health officials who defended the order as a rare but necessary step to contain a surge in the highly contagious disease that has infected at least 329 people so far, most of them children from Orthodox Jewish communities in the borough of Brooklyn.

Another 222 cases have been diagnosed elsewhere in New York state, mostly in a predominantly ultra-Orthodox Jewish neighborhood of Rockland County, northwest of Manhattan.

The New York outbreaks are part of a larger resurgence of measles across the country, with at least 555 cases confirmed in 20 states, according to the U.S. Centers for Disease Control and Prevention.

Health experts say the virus, which can cause severe complications and even death, has spread mostly among school-age children whose parents declined to get them vaccinated. Most profess philosophical or religious reasons, or cite concerns — debunked by medical science — that the three-way measles-mumps-rubella (MMR) vaccine may cause autism.

The judge rejected the parents’ contention that the vaccination order was excessive or coercive, noting it does not call for forcibly administering the vaccine to those who refuse it.

He also dismissed assertions in the petition disputing the “clear and present danger” of the outbreak. “Vaccination is known to extinguish the fire of contagion,” the judge said.

Secret identities

The vaccination order, which was extended this week, requires residents of certain affected Brooklyn neighborhoods to obtain the MMR vaccine unless they can otherwise demonstrate immunity to measles, or face a fine.

The court challenge was brought in Brooklyn’s Supreme Court by five people identified only as parents living in the affected neighborhoods. Their identities were kept confidential to protect their children’s’ privacy, their lawyers said.

In court on Thursday, they told Knipel the city had overstepped its authority and that quarantining the infected would be a preferable approach.

Robert Krakow, an attorney for the parents, estimated that just 0.0006 percent of the population of Brooklyn and Queens had measles. “That’s not an epidemic,” he said. “It’s not Ebola. It’s not smallpox.”

The health department’s lawyers argued that quarantining was ineffective because people carrying the virus can be contagious before symptoms appear.

The judge cited 39 cases diagnosed in Michigan that have been traced to an individual traveling from the Williamsburg community at the epicenter of Brooklyn’s outbreak.

The surge in measles there originated with an unvaccinated child who became infected on a visit to Israel, where the highly contagious virus is also running rampant.

The number of measles cases worldwide nearly quadrupled in the first quarter of 2019 to 112,163 compared with the same period last year, the World Health Organization said this week. (VOA)
