New Delhi amongst top cities where hearing is most degraded

March 5, 2017

Washington D.C, Mar 5: Urban noise pollution and hearing loss are closely linked, according to rankings of 50 large cities in both categories released on Friday.cars

High-decibel urban areas-such as Guangzhou, New Delhi, Cairo and Istanbul-topped the list of cities where hearing was most degraded, researchers reported.

Likewise, cities least afflicted by noise pollution-including Zurich, Vienna, Oslo and Munich-registered the lowest levels of decline in hearing.

This statistical link does not necessarily mean the constant din of city life is the main driver of hearing loss, which can also be caused by infections, genetic disorders, premature birth, and even some medicines.

The findings are also preliminary, and have yet to be submitted for peer-reviewed publication.

"But this is a robust result," said Henrik Matthies, managing director of Mimi Hearing Technologies, a German company that has amassed data on 200,000 people drawn from a hearing test administered via cell phones.

"The fact that noise pollution and hearing loss have such a tight correlation points to an intricate relationship," he told AFP.

Researchers at Mimi and Charite University Hospital in Berlin explored the link by constructing two separate databases.

The first combined information from the World Health Organization (WHO) and Norwegian-based technology research group SINTEF to create a noise pollution ranking for cities around the world.

Stockholm, Seoul, Amsterdam and Stuttgart were also among the least likely to assault one's ears, while Shanghai, Hong Kong and Barcelona came out as big noise makers.

Paris-one of the most densely populated major cities in Europe-scored as the third most cacophonous.

The ranking for hearing loss drew from Mimi's phone-based test, in which respondents indicated age and sex. Geo-location technology pinpointed the cities.

The results were measured against a standard for age-adjusted hearing.

On average, people in the loudest cities were ten years "older"-in terms of hearing loss-than those in the quietest cities, the study found.

Stacked side-by-side, the two city rankings are remarkably similar, suggesting more than an incidental link.

The findings highlight the need for better monitoring, the researchers said.

"While eye and sight checks are routine, ear and hearing exams are not," said Manfred Gross, head of the department of Audiology and Phoniatrics at Charite University Hospital.

"The earlier hearing loss is detected, the better the chances are for preventing further damage."

Collaborations between scientists and private companies that collect health-related information from consumers are becoming more common in the era of Big Data.

California-based DNA genetic testing company 23andMe, for example, has worked extensively with university researchers to ferret out rare genetic disorders by combing through mountains of anonymous data from its clients.

Also on Friday, World Hearing Day, the WHO released figures showing annual costs of unaddressed hearing loss of between $750 billion and $790 billion globally.

Direct health care costs were calculated to be up to $107 billion, with loss of productivity due to unemployment or early retirement about the same.

"Societal costs"-stemming from social isolation, inability to communicate and stigma-were estimated at more than $500 billion.

In a recent editorial, the medical journal The Lancet said hearing loss is a "silent epidemic", noting that proper care remains out of reach for millions of people.

Panaji, May 11: Amid the COVID-19 outbreak, most of the people are more concerned about the health of their near and dear ones than their own well-being, says a study conducted by a leading business school in Goa.

People are now more conscious about any bodily changes, and even mild cold, cough and sneezing, it says.

The study, on public's reaction towards COVID-19 outbreak by gauging their psychological response in terms of anxiety and their coping behaviour, was conducted by the Goa Institute of Management's Dr Divya Singhal and Prof Padhmanabhan Vijayaraghavan.

It took into account inputs from 231 respondents residing in various parts of the country.

"Nearly 82.25 per cent of the respondents were more worried about the health of their loved ones than their own well-being," Singhal said.

"Majority of the respondents have become conscious of any bodily changes, sensations, a mild cold, cough, sneezing and experience concern, and attribute those changes to the symptoms of COVID-19," she said.

Besides, more than 50 per cent of the respondents said their social media usage has gone up as well as their time spent on watching movies and shows through online medium, the official said.

The respondents agreed that their technology usage to connect with friends and relatives has gone up, she said.

The study also indicated that a large group of respondents found it "depressing" to read forwarded messages on the deadly disease.

"An overwhelming majority of the respondentsagreed that they discourage unverified forwarded messages about COVID-19 on social media," says the study.

It also found that 41 per centof the respondents were not doing any physical activity, like yoga, during the lockown period, while another 19 per cent were not sure about engaging themselves in physical activities.

Besides, 57 per cent of the respondents were not engaged in any mind-calming practices like meditation, and 18 per cent were not sure about taking up meditative practices, the study said.

The respondents included 145 men and 86 women, aged 18 and above, with nearly 60 per cent of them residing in non- metro cities and rest from metros.

About 47.62 per cent of the respondents were employed in private or government sectors, and the remaining included students, retired persons and homemakers.

Washington D.C, Feb 27: New research shows that adults who have low fruit and vegetable intake are more likely to be diagnosed with an anxiety disorder.

"For those who consumed less than 3 sources of fruits and vegetables daily, there was at least at 24% higher odds of anxiety disorder diagnosis," says the lead author of the Canadian Longitudinal Study, Karen Davison, who is a health science faculty member, nutrition informatics lab director at Kwantlen Polytechnic University, (KPU) and North American Primary Care Research Group Fellow.

"This may also partly explain the findings associated with body composition measures. As levels of total body fat increased beyond 36%, the likelihood of anxiety disorder was increased by more than 70%," states co-author Jose Mora-Almanza, a Mitacs Globalink intern who worked with the study at KPU.

"Increased body fat may be linked to greater inflammation. Emerging research suggests that some anxiety disorders can be linked to inflammation," says Davison.

In addition to diet and body composition measures, the prevalence of anxiety disorders also differed by gender, marital status, income, immigrant status and several health issues.

An important limitation of the study was that the assessment of anxiety disorders was mostly based upon self-reporting of a medical diagnosis.

"It is estimated that 10% of the global population will suffer from anxiety disorders which are a leading cause of disability," says Karen Davison

"Our findings suggest that comprehensive approaches that target health behaviours, including diet, as well as social factors, such as economic status, may help to minimize the burden of anxiety disorders among middle-aged and older adults, including immigrants," she concluded.

After admitting that the world may have a COVID-19 vaccine within one year or even a few months earlier, the World Health Organisation (WHO) on Friday said that UK-based AstraZeneca is leading the vaccine race while US-based pharmaceutical major Moderna is not far behind.

WHO Chief Scientist Soumya Swaminathan stated that the AstraZeneca's coronavirus vaccine candidate is the most advanced vaccine currently in terms of development.

"I think AstraZeneca certainly has a more global scope at the moment in terms of where they are doing and planning their vaccine trials," she told the media.

AstraZeneca's Covid-19 vaccine candidate developed by researchers from the Oxford University will likely provide protection against the disease for one year, the British drug maker's CEO told Belgian radio station Bel RTL this month.

The Oxford University last month announced the start of a Phase II/III UK trial of the vaccine, named AZD1222 (formerly known as ChAdOx1 nCoV-19), in about 10,000 adult volunteers. Other late-stage trials are due to begin in a number of countries.

Last week, Swaminathan had said that nearly 2 billion doses of the COVID-19 vaccine would be ready by the end of next year.

Addressing the media from Geneva, she said that "at the moment, we do not have a proven vaccine but if we are lucky, there will be one or two successful candidates before the end of this year" and 2 billion doses by the end of next year.

Scientists predict that the world may have a COVID-19 vaccine within one year or even a few months earlier, said the Director-General of the World Health Organization even as he underlined the importance of global cooperation to develop, manufacture and distribute the vaccines.

However, making the vaccine available and distributing it to all will be a challenge and will require political will, WHO chief Tedros Adhanom Ghebreyesus said on Thursday during a meeting with the European Parliament's Committee for Environment, Public Health and Food Safety.

One option would be to give the vaccine only to those who are most vulnerable to the virus.

There are currently over 100 COVID-19 vaccine candidates in various stages of development.
