New software for early diagnosis of Alzheimer's

December 31, 2012

Washington, Jan 1: Scientists have developed a new software that could significantly boost the early diagnosis of Alzheimer's disease.

The comparative software called PredictAD contrasts patient's measurements with those of other patients kept in large databases, then visualises the status of the patient with an index and graphics.

The support system and imaging methods were developed by VTT Technical Research Centre in Finland and Imperial College London, 'Gizmag' reported.

Researchers used material compiled in the US by the Alzheimer's Disease Neuroimaging Initiative based on the records of 288 patients with memory problems.

Nearly half of them were diagnosed with Alzheimer's disease on average 21 months after the initial measurements, which is about the same as the current European average of 20 months.

Researchers concluded that half of the patients could have been diagnosed with the disease around a year earlier, or nine months after the initial measurements. They say the accuracy of the predictions was comparable to clinical diagnosis.

There are several advantages of an early diagnosis of Alzheimer's. It can delay institutionalisation and slow down the progress of the disease.

It is also advantageous from the clinical trials perspective because if patients caught early can be included in the trials, treatment is likely to be more effective.

Working towards the same goal, researchers at Lancaster University in the UK recently developed an eye test method to detect early signs of Alzheimer's.

An estimated 35.6 people live with dementia worldwide, and that number is expected to rise to 65.7 million by 2030, according to 2010 figures.

The study findings were published in the Journal of Alzheimer's Disease.

Google on Monday announced it is gradually winding down its free public Wi-Fi Station programme currently available at over 400 railway stations in India, and will work with the Indian Railways and Railtel Corporation to help them with existing sites so they can remain useful resources for people.

Google launched its Station initiative in India in 2015 to bring fast, free public Wi-Fi to over 400 of the busiest railway stations in the country by mid-2020.

"We crossed that number by June 2018 and implemented Station in thousands of other locations around the country in partnership with telecommunications companies, ISPs and local authorities," Caesar Sengupta, Vice President, Payments and Next Billion Users, Google, said in a statement.

"Over time, partners in other countries asked for Station too and we responded accordingly. We're grateful for these partnerships, especially with the Indian Railways and the Government of India, that helped us serve millions of users over the last few years," he added.

According to Google, the decision to shut Station has been taken keeping the affordable mobile data plans and mobile connectivity in mind that is improving globally including in India.

"India, specifically now has among the cheapest mobile data per GB in the world, with mobile data prices having reduced by 95 per cent in the last 5 years, as per TRAI in 2019," said Sengupta.

The Indian users consume close to 10GB of data, each month, on average, according to reports.

"Our commitment to supporting the next billion users remains stronger than ever, from continuing our efforts to make the internet work for more people and building more relevant and helpful apps and services," Sengupta noted.

Global networking giant Cisco last year teamed up with Google to roll out free, high-speed public Wi-Fi access globally, starting with India.

The first pilot under the partnership was rolled out at 35 locations in Bengaluru.

Sengupta said that in addition to the changed context, the challenge of varying technical requirements and infrastructure among our partners across countries has also made it difficult for Station to scale and be sustainable, especially for our partners.

"And when we evaluate where we can truly make an impact in the future, we see greater need and bigger opportunities in building products and features tailored to work better for the next billion user markets," he said.

New Delhi, Apr 17: The Indian Railways turned 167 years old on Thursday and for the first time ever, its trains did not carry any passengers on its birthday and instead stood idle in the yards waiting for the nationwide lockdown to end.

On this day 167 years ago, the wheels of the first passenger train in the country from Mumbai to Thane started rolling.

In 1974, Indians experienced life without trains for the first time. In May 1974 during the strike of the railways that lasted for around three weeks, drivers, station masters, guards, track staff and many others went on 'chakka jam' demanding fixed working hours for train drivers and an across-the-board pay hike.

"I can recall those times vividly. I remember that our leader George Fernandes had almost secured a deal with the then railway minister, but it fell through when it was taken to the then Prime Minister Indira Gandhi," All India Railwaymens Federation General Secretary Shiv Gopal Mishra, who was an apprentice in the railways at that time, told PTI.

"Fernandes was arrested in Lucknow. The workers went through a lot at that time. But those were days that angry workers had refused to give in and took great risks to get their demands met," he said.

However, just like this time, four decades ago too freight trains carrying essential supplies were run and the unions agreed to let some passenger trains run on the trunk routes like the Kalka Mail from Howrah to Delhi.

"Never ever in its history, there has been such a long interruption of services. Not during the World Wars, not during the 1974 railway strike, or any other national calamity or natural disaster," a railway spokesperson said.

The first Indian Railways passenger train was flagged off on April 16, 1853, from Mumbai to nearby Thane.

On Thursday, the Railway Ministry wished the railways a happy birthday on Twitter - "Today, 167 years ago with the zeal of 'never to stop' the wheels of the first passenger train from Mumbai to Thane started rolling. For the first time, passenger services are stopped for your safety. Stay indoors & make the nation victorious," it said.

Railway has suspended all passenger services since March 25 till May 3 due to the coronavirus outbreak. Around 15,523 trains run by the railways have been affected including 9,000 passenger trains and 3,000 mail express services which are run daily. It caters to over 20 million passengers every day.

According to the Union health ministry, the death toll due to coronavirus rose to 414 and the number of cases to 12,380 in the country on Thursday.
