Australian researchers confirm stress makes you sick

Wednesday, December 7, 2005

Australian researchers say they have scientifically proven that stress causes sickness. The Garvan Institute in Sydney has discovered that a hormone, known as neuropeptide Y, (NPY) is released into the body during times of stress. Their findings show the hormone can stop the immune system from functioning properly.

Neuropeptide Y is one of those hormones that gets unregulated or released from neurones when stressful situations occur…it’s known for example that it regulates blood pressure and heart rates so your heart rate goes up but it hasn’t been known that it actually can affect immune cells as well,” said Professor Herbert Herzog, one of the researchers.

Herzog feels it is good to finally have proof of something people have suspected for so long.

“Now we have proven without doubt that there is a direct link and that stress can weaken the immune system and that makes you more vulnerable when you for example have a cold or flu and even in the more serious situations such as cancer can be enhanced in these situations,” said Herzog.

The Garvan Institute study centres on two key events that enable the human body to recognise foreign substances and control invaders. When our body encounters a pathogen (bacteria and viruses), the immune cells retain and interrogate suspects. Their activation is made possible by NPY. These cells then return to the lymph nodes, which are found all over the body, with information about the foreign invaders. The lymph nodes are where decisions about defence are made.

“Most of us expect to come down with a cold or other illness when we are under pressure, but until now we have mostly had circumstantial evidence for a link between the brain and the immune system,” said lead Garvan researcher, associate Professor Fabienne Mackay. “During periods of stress, nerves release a lot of NPY and it gets into the bloodstream, where it directly impacts on the cells in the immune system that look out for and destroy pathogens (bacteria and viruses) in the body.”

In the case of bacteria and viruses, TH1 cells are part of the attack team that is sent out on the ‘search and destroy’ mission. But when their job is done they need to be turned ‘off’ and the immune system reset. The same hormone, NPY, that activates the sentry cells now prompts the TH1 cells to slow down and die.

“Under normal conditions, circulating immune cells produce small amounts of NPY, which enables the immune cells on sentry duty and the TH1 immune cells to operate – it’s a yin and yang kind of situation. But too much NPY means that the TH1 attack is prevented despite the foreign invaders being identified – and this is what happens during stress,” added McKay.

The impact of stress on the body has been observed in athletes. Ph. D researcher at the University of Queensland, Luke Spence, together with the Australian Institute of Sport, studied elite and recreational athletes over five months.

They found elite athletes were more susceptible to respiratory diseases under stress.

“A lot of elite athletes put themselves through vast amounts of physical stress in their training, but also their emotional, psychological stress of feeling the pressure of Australia on their shoulders, wanting to compete and wanting to do their best,” said Spence.

It’s not just athletes who are prone to stress. Pressures at work and at home may cause emotional and mental stress that can be equally damaging. Almost a third of all work absenteeism in Australia is due to illness, costing employers over $10 billion a year.

“I think it has a huge impact for the work force and also for employers – if their employees are constantly stressed, constantly under pressure, they are more likely to get sick,” Spence said.

Further research could lead to the development of new drugs which may inhibit the action of the neuropeptide Y hormone.

Herzog warns people to minimise stress before it becomes a problem.

“Relaxation methods like yoga will help you to prevent that but there will still be people out there that are not responding to that and treatment by interfering with the system will be important,” he said. “There’s obviously some time until such a treatment will be available but this is something we will definitely work towards.”

The Garvan research will be published in the Journal of Experimental Medicine, Volume 202, No. 11.

Andrea Muizelaar on fashion, anorexia, and life after ‘Top Model’

Monday, November 26, 2007

In the 18 months since Andrea Muizelaar was crowned winner of the reality TV series Canada’s Next Top Model, her life has been a complete whirlwind. From working in a dollar store in her hometown of Whitby, Ontario, to modeling haute couture in Toronto, she had reached her dream of becoming a true Top Model.

But at what cost? Unknown to casual television viewers, Muizelaar had been enveloped in the eating disorder anorexia nervosa, which inevitably became too much for her to bear. She gave up modeling and moved back to Whitby, where she sought treatment for her disorder, re-entered college, and now works at a bank. Where is she now? Happy and healthy, she says.

Recently Andrea Muizelaar sat down with Wikinews reporter Mike Halterman in a candid interview that stretched to nearly two hours, as she told all about her hopes and aspirations, her battle with anorexia, and just what really happened on Canada’s Next Top Model.

US airlines eke out US$12 million profit in first quarter

US airlines eke out US$12 million profit in first quarter

Wednesday, June 30, 2010

US airlines in the first quarter of 2010 managed to eke out a US$12 million profit, mostly from “ancillary” services like checked baggage fees, pet transportation fees and more.

Compared to the first quarter of 2009, checked baggage fees soared 33% to $769 million. The airlines also reaped $554 million in reservation change fees, and made $534 million from other ancillary sources; such services (including checked baggage fees, reservation change fees, etc.) made up 21.7% of Spirit Airlines’ income, the highest in the industry.

The US airline industry is made up of 21 carriers, according to the U.S Department of Transportation.

The five “network” or legacy carriers—including United Airlines, Delta Air Lines, Continental Airlines, American Airlines and US Airways—continue to struggle and posted a $163 million loss as a group. Delta Air Lines had the highest profit, at $107 million, while American Airlines was at the other side of the carriers, with a $322 million loss.

Low-cost carriers fared better, posting a $115 million profit as a group, with Southwest Airlines having the largest profit, at $54 million, while Allegiant Air’s profit margins were the highest of the budget carriers at 20%. Regional airlines made a $60 million profit.

The world’s airlines expect a US$2.5 billion profit as a whole, despite an earlier forcast of a loss. However, many investors and groups, such as the International Air Transport Association (IATA), are somewhat doubtful of this number, as oil prices are expected to remain volatile, leading to the possibility of high prices cutting into airlines’ profits.

Sunday, August 26, 2007Miami Dade Fire Rescue, Urban Search and Rescue Florida Task Force 1 Members were on the scene since last night. Search dogs worked the scene all night.

According to current reports, sometime early this morning, an apartment building in Brittons Hill, Barbados fell into a cave below.

Five family members are known to be trapped in the collapse, although reports have not be made as to whether these are the only individuals involved. Rescue workers, as well as several prominent politicians are currently on the scene; two cranes have been deployed to remove debris. Evacuation has occurred, with an extension of this area being discussed.

Miami Dade Police arrived on the scene late Sunday night and are now in a joint effort with the Barbados Defence Force, Barbados Fire Service and Royal Barbados Police Force to rescue possible survivors. Prime Minister Owen Arthur also stated that surveys are currently being conducted to determine the stability of the surrounding area, and only after these reports have been compiled will residents know whether they will be able to return to their homes.

A cadaver dog was sent into the cavern and has identified two areas where there are possible dead bodies. Sadly it is no longer a rescue mission but recovery one.

England’s elderly face human rights breaches in home care system

England’s elderly face human rights breaches in home care system
Published by

Wednesday, November 23, 2011

A report published today by the Equality and Human Rights Commission (EHRC) finds that, in many cases, England’s home care system breaches the human rights of the elderly it is supposed to serve. The Close to home: older people and human rights in home care report is the result of a twelve-month investigation into care generally provided by local authorities.

Approximately half of those receiving home care, plus friends and family, providing evidence to the inquiry were satisfied with the quality of care provided. However, the report stresses that there are “systemic problems” arising from “a failure to apply a human rights approach to home care provision”. The report asserts that it is generally not the fault of individuals providing care, but serious problems exist as local authorities seem unaware of their obligations under the Human Rights Act and fail to commission, procure, and monitor care accordingly.

The report says articles two, three and eight of the European Convention on Human Rights are frequently being breached. These, respectively, cover an individual’s right to life, protection from inhumane and degrading treatment, and respect for dignity and personal independence. Criticisms include that care is not provided in a common-sense manner, and funding of care for the elderly is at lower levels than for younger people with similar problems and needs.

Do you have elderly relatives receiving care at home? Is the support provided adequate?

The EHRC’s investigation highlights a range of recurring complaints and attempts to identify the underlying causes; cost is repeatedly mentioned, with use of the private-sector leading to some local authorities offering a “one size fits all” service leaving many elderly feeling they are “a task to be undertaken” and have “little or no choice” as to help received, or when care workers visit. A failure to invest in care workers is noted, with significant responsibility and the wide range of skills required being rewarded with low pay and status; this, the report states, adversely impacts staff retention and, a high turnover of care workers can put the security of care recipients at-risk.

Within the wider investigation, a commissioned independent social report by The Arndale Centre conducted in-depth interviews with a cross-section of 40 elderly individuals receiving home care. As-stressed in the report, those selected were not on the basis of good, or bad, experiences with their – mainly local authority-provided – care. It highlights a widespread feeling amongst those interviewed that they are treated “like a number”, and that aspects of the care provided lead to, or fail to resolve, feelings of social isolation.

The Manchester-based Arndale Centre report concludes that, “[t]he general picture is of a wider home care system in which older people are noteffectively involved: which they do not understand, and which does not often make the extra effort required to involve them in ways tailored to their state of health and other needs”.

nobody to talk [to] face to face. Nobody will knock on that door,[…] a life of isolation.

A recurring theme in the responses of those interviewed is the social isolation that their home care is not adequately addressing. One male interviewee in his seventies who previously used a scooter to get about said in his interview, “I haven’t been out of the house now for about four weeks. I daren’t. The last time I went out on the scooter I hit the kerb and it frightened the living daylights out of me.” Another, an 85-year-old woman who lives alone, expressed sadness at her inability to do normal things, “I would love to go to town to do some shopping. I haven’t been to town for about two years… Wander round the town and have a cup of tea… I’d love that.”

The social isolation many elderly experience was summed up neatly by another woman in her eighties in her interview: “When you go now, I will maybe not talk to anybody till tomorrow; maybe the whole of tomorrow nobody to talk [to]… face to face. Nobody will knock on that door, that is it, a life of isolation.”

The EHRC, having commissioned this report in the face of funding changes and reform of the care system, intends to press for legislative changes to ensure those receiving care at home are given the same protections under the Human Rights Act as those in residential care. In the conclusions of their report they offer to work with, and support, local authorities in understanding and delivering care that respects peoples’ rights and dignity; and, recommend better guidance as to the choices available to the elderly, and their families, be made available.

Cadillac unveils Obama’s ‘Beast’, the 2009 Presidential State Car

Saturday, January 17, 2009

The US Secret Service has released the first photos Wednesday of the new presidential limousine that will transport Barack Obama down Pennsylvania Avenue next Tuesday as part of the 56th Presidential inaugural parade after he is sworn in at the Capitol. The First Limo – the 2009 Cadillac Presidential Limousine – will replace President Bush’s Cadillac DTS Presidential Limousine that rolled out in 2004.

Nicknamed “The Beast”, the hulking machine is a new model year 2009, modified limousine. According to General Motors, the new “2009 Cadillac Presidential Limousine” is the first not to carry a specific model name. The Obama Mobile was introduced on January 14 with noticeably different styling borrowed from the Cadillac Escalade and STS, while the suspension is most likely related to the Chevrolet Kodiak medium-duty truck.

Do you like the car? What would you like to see Obama driven around in?

Mr. David Caldwell of General Motors has revealed that the sleek black car would include a hand-crafted interior and “state of the art electronics.” The car’s high-tech security features include five-inch-thick (12.7-centimeter-thick) bombproof glass, tough-as-nails tires, and a sealed interior that’s invulnerable to chemical attack. The armoured limousine has been heavily modified to withstand potential attacks by weapons or bombs. The San Francisco Chronicle puts it in a proper perspective noting, “a half-inch of transparent armor is enough to stop a .44 Magnum round at point-blank range; at a thickness of 1 1/4 to 1 1/2 inches, the same material can withstand higher-velocity bullets fired from military assault rifles.”

According to spy photographer, Brenda Priddy, and General Motors, the limousine, which has the intricate, dual-textured grille, is also equipped with standard Goodyear Regional RHS truck tires in a 285/70R19.5 size, on 19.5-inch wheels. The rims have a run-flat device (manufactured by Hutchinson Industries). Xenon headlights from the Escalade are installed in the front, while the rear has some STS part. The doors are at least 20 centimeters (8 inches) thick. It carries the US flag on the front fenders and an embroidered Seal of the President of the United States is affixed to several panels in the back.

According to the US Secret Service, the vehicle would be a “valuable asset” in providing the President with the highest level of protection. “Although many of the vehicle’s security enhancements cannot be discussed, it is safe to say that this car’s security and coded communications systems make it the most technologically advanced protection vehicle in the world,” Nicholas Trotta, Assistant Director for the Office of Protective Operations said in a statement. The new limousine is the responsibility of White House Transportation Agency.

One of the specifications is that we don’t talk about the specifications.

The Presidential State Car is the official state car used by the President of the United States. It is informally known as “Cadillac One”. The current Presidential State Car is a 2005 hand-crafted, armored, and stretched DTS (DeVille Touring Sedan) built on a GM four-wheel drive platform. It was first used on the second inauguration parade of George W. Bush in 2005. But the version to be used by President Obama uses a GMC Topkick chassis, while maintaining the Cadillac exterior.

The President of the United States travels in one of two armoured Cadillac limousines based upon the normal sedan, the Cadillac DTS, with heavy customisation. Lincoln cars have also been used in the past, most notably by President John F Kennedy. The current limousines were custom-built by O’Gara, Hess and Eisenhart, founded in Fairfield, Ohio in 1942. It specializes in armouring limousines for presidents and heads of state.

President William McKinley was the first US president to ride in an automobile. However, it was President Theodore Roosevelt who rode on the first government-owned car, a white Stanley Steamer. Roosevelt’s successor, William Howard Taft, was the first president to use a presidential state car that was permanently stored in the White House garage.

Meanwhile, Obama’s 2005 Chrysler 300C Hemi was auctioned on eBay with a starting bid of $100,000 and a buy-it-now price of $1,000,000. It has less than 21,000 miles on it and is in like-new condition. He leased the car in 2004 and traded it for a Ford Escape Hybrid in 2007. The car was sold to Tim O’Boyle.

Broward County Sheriff’s police dog killed in shootout in Florida

Thursday, July 17, 2008

A man shot and killed a Broward County Sheriff’s Office police dog in Miami Beach after a two-county chase in Florida early Thursday morning.

The shooter, Delvin Lewis, 27, was firing shots at his girlfriend during a domestic dispute in Oakland Park. When police arrived, the suspect got into his car and fled, engaging roughly 20 cruisers in a 30-mile chase which ended near Mount Sinai Medical Center’s emergency room in Miami Beach. An exchange of gunfire followed in which Lewis reportedly killed the dog. ER doctors tried to save the animal but it was too late.

The shooter was also struck and has been taken to Jackson Memorial Hospital where he remains with no life threatening injuries.

According to a Mount Sinai spokeswoman hospital facilities are now accessible after the authorities locked down the area for three hours following the shooting.

Lewis has been arrested 26 times by Florida authorities including one in July 2003 in which he injured a police dog striking him repeatedly on the head with a cellphone.The suspect has been charged with aggravated assault with a motor vehicle on a law enforcement officer, aggravated fleeing and eluding, resisting an officer with violence and principal in the death of a police dog.

Hitting a police dog is a third-degree felony punishable by up to five years in jail, while killing a police officer is a capital offense which can lead to the death penalty.

Miami-Dade Police Department is handling the investigation which involves Broward Sheriff Office and Miami Beach police.

Lewis has been in and out of jail since 2000 and had been arrested for domestic battery in 2000 and 2004, when he beat a pregnant woman.

The dog, whose name was Oozi, was a 7-1/2 years old Belgian Malinois assigned to BSO’s Cooper City district. He was trained in narcotics and helped in hundreds of arrests in his career, including 35 this year.

Oozi and his partner, Deputy Gerald Wengert, were named BSO’s Employees of the month in May for their role in the apprehension of three burglary suspects.

U.S. automaker Chrysler wants to eliminate 789 dealerships

Thursday, May 14, 2009

American automobile manufacturer Chrysler LLC has said that it wants to eliminate 789, or about a quarter, of its 3,200 dealers by early June. In a bankruptcy court filing on Thursday, the firm stated its network has too many dealers competing between each other and is antiquated.

A June 3 hearing has been scheduled in the US Bankruptcy Court to determine whether the move should be approved.

“This is a difficult day for us and not a day anybody can be prepared for,” said Jim Press, the Vice Chairman of Chrysler.

Company executives said the firm is trying to eliminate dealers with poor performances, and retain those who make the strongest sales. Over 50% of the dealerships that are to be eliminated sell less than a hundred automobiles per year.

“We recognize in the short term we will see some loss of sales. But based on the long term … the dealer [network] is key and it’s going to be very strong, powerful, with a much better financial viability,” said Press.
