GENEVA – More than 1 billion young people risk damaging their hearing through excessive use of smartphones and other audio devices, the U.N. warned Tuesday, proposing new safety standards for safe volume levels.

In a bid to safeguard hearing, the World Health Organization and International Telecommunications Union issued a non-binding international standard for the manufacture and use of audio devices.

Young people are particularly prone to risky listening habits.

Around half of those between the ages of 12 and 35, or 1.1 billion people, are at risk due to “prolonged and excessive exposure to loud sounds, including music they listen to through personal audio devices,” the UN health agency said.

WHO chief Tedros Adhanom Ghebreyesus pointed out that the world already has “the technological know-how to prevent hearing loss.”

“It should not be the case that so many young people continue to damage their hearing while listening to music,” he said in the statement.

Young people, he said, “must understand that once they lose their hearing, it won’t come back.”

Currently, about 5 percent of the global population, or some 466 million people, including 34 million children, suffer from disabling hearing loss.

WHO said it remained unclear how many of them had damaged their hearing through dangerous use of audio devices.

It insisted though that the new standard developed with ITU would go a long way to “safeguard these young consumers as they go about doing something they enjoy.”

WHO considers a volume above 85 decibels for eight hours or 100 decibels for 15 minutes as unsafe.

The Safe listening devices and systems standard calls for a “sound allowance” software to be included in all audio devices, to track the volume level and duration of a user’s exposure to sound, and to evaluate the risk posed to their hearing.

This system could alert a user if they have dangerous listening habits.

WHO is also calling for parental as well as automatic volume controls on audio devices to prevent dangerous use.

While some smartphones and other audio devices already offer some of these features, the U.N. would like to see a uniform standard used to help protect against disabling hearing loss.

“Think of it like driving on a highway, but without a speedometer in your car or a speed limit,” Shelly Chadha of the WHO told reporters in Geneva.

“What we’ve proposed is that your smartphones come fitted with a speedometer, with a measurement system which tells you how much sound you’re getting and tells you if you are going over the limit.”

WHO weighs H7N9 risk as cases mount

chicken_in_wicker_cage1208742
Ivonne Wierink / ThinkstockMost patients in the current H7N9 outbreak wave have had contact with poultry or live-bird markets.

Against the backdrop of four new H7N9 influenza illnesses reported from China today, a detailed look at the second wave of the outbreak reveals that cases are trending slightly younger, with a lower case fatality rate (CFR), though severe pneumonia is still one of the disease’s hallmarks.

So far more than 80 new cases—the large majority from the first of the year—have been reported in the outbreak’s second spike that began in October. Over the past few weeks China has often reported five to seven new cases each day, equaling the pace seen during last spring’s first-wave peak.

Cases trending younger, less deadly?

World Health Organization (WHO) experts said today in their latest risk assessment that most cases in the first wave involved middle-aged or older men, but the age distribution in the new wave isn’t as skewed toward older age-groups. The mean age in the new surge of cases is slightly lower than the first wave: 52 years compared with 58 years.

H7N9 is still striking males more frequently than females, and the CFR is not as high as the outbreak’s first wave, the WHO said. It cautioned, however, that CFR patterns need to be monitored closely, because many of the recently infected patients are still hospitalized. Some milder cases have been reported, but it’s clear that H7N9 infections are marked by rapidly progressing severe pneumonia, according to the risk assessment.

Lab analysis of H7N9 samples from patients, animals, and the environment collected during the second wave shows that the hemagglutinin (HA) and neuraminidase (NA) genes are similar to viruses from the first wave, the report said. It added that they are also similar to the influenza A/Anhui/1/2013 strain recommended for H7N9 vaccine development.

Tests on a subset of recent viruses to monitor for antiviral resistance have identified no markers linked to resistance to neuraminidase inhibitors, including oseltamivir (Tamiflu) and zanamivir (Relenza).

Resistance to frontline treatments such as oseltamivir and zanamivir has been a worry since the outbreak’s early days, when an NA resistance marker was found in one of the first three lab-confirmed H7N9 cases. The resistant viruses have also been linked to treatment failures in some severely ill patients.

Several questions remain about the source of human infections, though most of the evidence points to exposure to infected live poultry and their contaminated environments, the WHO said. It added that most patients who were sickened by H7N9 were exposed to birds or live-poultry markets, that H7N9 viruses from humans are genetically similar to ones collected from birds and the environment, and that live-poultry markets linked to human infections are more likely to yield positive H7N9 samples.

The WHO’s analysis found no increase in the number of illness clusters, including healthcare-associated ones, that would point to any increased risk of human-to-human transmission. It said an investigation into a recent infection in one health worker, presumably that of a 31-year-old doctor from Shanghai whose H7N9 death was reported this week, found that the patient may have been exposed to poultry or a contaminated environment. So far no other H7N9 cases linked to the patient have been identified.

Though the virus doesn’t seem to transmit easily among humans, the detection of several less severe cases during flulike illness surveillance, along with continuing severe cases, shows that continued vigilance is needed, the WHO said. Overall, the public health risk hasn’t changed from the WHO’s last assessment in December.

More sporadic H7N9 cases are expected to be reported in humans, especially with increases in poultry production, trade, and transport in advance of China’s Lunar New Year holiday season and because H7N9 seems to be following a more active winter seasonal pattern seen with other avian influenza viruses, the WHO said. Travel-associated cases could occur, but the agency said the threat of international spread is low, unless the virus adapts for more efficient human-to-human transmission.

China reports four more cases

The four new case-patients from China include a 71-year-old man from Jiangsu province whose illness was reported late yesterday and three from Zhejiang province: a 53-year-old man, a 71-year-old man, and a 63-year-old woman.

According to a translation of a provincial health ministry report posted by the Avian Flu Diary infectious disease news blog, the patients from Zhejiang province are all hospitalized in critical condition. A statement from Hong Kong’s Centre for Health Protection (CHP) said the patient from Jiangsu province is also hospitalized.

The new cases boost the outbreak total to 220, according to a running tally updated each day with patients’ details by the FluTrackers infectious disease message board. The group’s total includes the case of an asymptomatic child that’s not included in WHO totals. The unofficial number of deaths is 57.

In a related development today, the WHO released more details about five more lab-confirmed cases it received from China on Jan 20. Hong Kong’s CHP had announced only basic information about the cases on Jan 20.

The patients include two people from Shanghai who died from their infections, the 31-year-old male doctor noted above and a 77-year-old man, as well as three patients from Zhejiang province, all who are hospitalized. They are a 55-year-old man, a 71-year-old woman, and a 63-year-old man. One is in serious and two in critical condition. All had been exposed to poultry before they got sick.

Poultry and environmental H7N9 findings

The WHO’s Western Pacific Region office (WPRO) today released a situation update, noting that continued vigilance is needed as case numbers rise, given the Lunar New Year activities and the unpredictable nature of flu viruses.

It also includes the results from China’s agriculture ministry on the latest H7N9 tests in birds and their environments from two of the outbreak’s hot spots: Guangdong and Zhejiang provinces.

In Zhejiang province, tests of 18 of 200 samples from three agricultural products markets and a wholesale market were positive for the H7N9 virus. Serologic testing of 85 samples yielded 7 positives.

In Guangdong province, testing at 151 sites found only 2 positives from two agricultural markets. Serologic testing of 2,192 samples in Guangdong found no positive specimens. The report also mentions positive tests reported earlier this month from a restaurant and live markets in Guangdong province.

減重先享「瘦」!必吃5種瘦素食物

479552181221
只要每天攝取500毫升的全脂牛奶,體內的瘦素濃度就會在1個月內增加3成。

 

今年接近尾聲了,跨年餐廳早已預訂一空,為什麼有的人去吃到飽餐廳,怎麼吃都吃不胖?有的人則是一餐下來,卻多增加1至2公斤體重?其實兩者差別在於容易吃胖的人,體內缺少「瘦素」Leptin所致。WHO建議,只要戒除一些壞習慣,同時攝取5種富含瘦素的食品,還是有機會控制體重。

什麼是瘦素?瘦素是由脂肪產生的一種激素,主要存在於脂肪細胞製造的白色脂肪組織內,它也可以從棕色脂肪組織,包括胎盤、卵巢、骨骼肌、胃、 乳腺上皮細胞、骨髓和肝產生,瘦素負責調節能量攝入和能量消耗。

瘦素濃度過低 導致脂肪堆積肥胖

2007年由美國生物學家道格拉斯•科爾曼(Douglas Coleman)所發現,找到真正的肥胖關鍵:瘦素含量高的人,新陳代謝高,能抑制脂肪合成;相反的,瘦素濃度過低,就會導致脂肪堆積,使體重增加。如果肥胖的人能有效吸收瘦素,就能夠促使脂肪燃燒,同樣有瘦身的機會。

一般人能維持正常體重,是由於能量的攝取與消耗達到平衡;而能量的攝取與消耗則是靠下視丘來調控,正巧瘦素即是作用於下視丘的受體在大腦的抑制食慾的地方,一旦缺乏瘦素,將無法控制食物攝取量,於是導致肥胖產生。

WHO推薦:TOP 5富含瘦素食物

世界衛生組織WHO推薦以下TOP 5富含瘦素的食品,可作為平時調整體重的參考:

★瘦素NO. 1:牛乳

英國諾丁漢大學的營養專家發現,能分泌飽食瘦素的最大功臣是乳類脂肪,只要每天攝取500毫升的全脂牛奶,體內的瘦素濃度就會在1個月內增加3成。

研究指出,每天吃兩個雞蛋,飽腹指數會上升20%。

研究指出,每天吃兩個雞蛋,飽腹指數會上升20%。

 

★瘦素NO.2:苦瓜

世界衛生組織的研究專員指出,苦瓜中含有高能清脂素,也是瘦素的一種。長期食用,能使飽和脂肪酸的吸收量減少40%。如果不喜歡苦苦的味道,可以用鹽水將苦瓜片浸泡4至5分鐘祛除苦味。

★瘦素NO. 3:雞蛋

研究指出,每天吃兩個雞蛋,飽腹指數會上升20%。日本營養專家也發現,將雞蛋與黃豆同時食用,可提高氨基酸在體內的吸收率。另外,食用雞蛋的最好時間是早上,每天早晨8點,瘦素的合成速度是晚上的2倍左右。

★瘦素NO. 4:蘋果醋

蘋果中的果膠成分和醋中的酵素相互作用,不僅能清洗消化道,還能讓身體產生抑制高血壓的鉀離子,促進瘦素的合成和分泌。但是,如果胃酸分泌過多,就不宜選擇蘋果醋瘦身,會使胃中的酸性環境失衡,造成消化不良,反而增加發胖的可能性。

★瘦素NO. 5:杏仁

杏仁中含有豐富的礦物質鎂,可以穩定血糖、提高血液中的瘦素。美國營養專家指出,杏仁細胞壁的成分還能降低人體對脂肪的吸收,在飲食平衡的情況下,讓瘦素發揮最大的效果。

控制體重 仍必需靠規律運動

根據研究發現,體內瘦素每增加1%,細胞內脂肪燃燒率快3%,平均體重就會下降0.37公斤。但是,僅靠攝取含有瘦素的食物,並非完全解決的方法;有研究顯示,持續且規律的運動,也可以幫助體內的瘦素維持正常濃度,所以,控制體重沒有捷徑,除了飲食還必需靠規律的運動,才能達到目的。

Polio outbreak fears in war-ravaged Syria

_70604387_polio_viruses,_tem-spl-1
Polio can be prevented but not cured

 

Experts are concerned that polio may have made a return to war-torn Syria.

The World Health Organization says it has received reports of the first suspected outbreak in the country in 14 years.

Syrian’s Ministry of Public Health is launching an urgent response, but experts fear the disease will be hard to control amid civil unrest.

Immunisation is almost impossible to carry out in regions under intense shellfire.

As a result, vaccination rates have been waning – from 95% in 2010 to an estimated 45% in 2013.

At least a third of the country’s public hospitals are out of service, and in some areas, up to 70% of the health workforce has fled.

Outbreak risks have also increased due to overcrowding, poor sanitation and deterioration in water supply.


Polio

  • Caused by a highly-infectious virus
  • Mainly affects children under five years
  • Can lead to irreversible muscle paralysis
  • A course of vaccines against polio can protect a child for life
  • Global eradication efforts continue
  • The disease remains endemic in only a few countries – Afghanistan, Nigeria and Pakistan
  • Mass vaccination is needed to eradicate polio

More than four million Syrians who have relocated to less volatile areas of the country are mostly living in overcrowded, unsanitary conditions.

The WHO says it is already seeing increased cases of measles, typhoid and hepatitis A in Syria.

Dr Jaouad Mahjour, director of the department for communicable diseases at WHO’s regional office for the Eastern Mediterranean, said: “Given the scale of population movement both inside Syria and across borders, together with deteriorating environmental health conditions, outbreaks are inevitable.”

The cluster of suspected polio cases was detected in early October 2013 in Deir al-Zour province.

Initial results from a laboratory in Damascus indicate that at least two of the cases could indeed be polio.

A surveillance alert has been issued for the region to actively search for additional potential cases. Supplementary immunisation activities in neighbouring countries are currently being planned.

WHO’s International Travel and Health recommends that all travellers to and from polio-infected areas be fully vaccinated against polio.

Most people infected with the poliovirus have no signs of illness and are never aware they have been infected. These symptomless people carry the virus in their intestines and can “silently” spread the infection to thousands of others before the first case of polio paralysis emerges.

Polio is spread by eating food or drink contaminated with faeces or, more rarely, directly from person-to-person via saliva.

No Case Of Mers Reported In Malaysia – Health Minister

PETALING JAYA, July 2 (Bernama) — There has been no report of Malaysians, including umrah pilgrims, returning from Saudi Arabia and displaying symptoms of the deadly Middle East Respiratory Syndrome (Mers).

Nevertheless, the health ministry exercises caution and takes the relevant measures, which includes checking the body temperatures of those arriving at the airport.

Minister Datuk Seri Dr S. Subramaniam said, any person found to display symptoms of fever, would be asked to go for further medical examination.

Dr Subramaniam said this when commenting on the spread of the Mers virus which took the lives of 33 people in Saudi Arabia since September last year.

Fifty-five others fell ill as a result of the virus, in that country, he added.

He was speaking to reporters after launching the Malaysian Private Hospitals Association International Health Exhibition 2013 here Tuesday.

The World Health Organisation (WHO) has yet to find a vaccine to prevent Mers, as well as the cause of the deadly infectious disease.

Fever, breathing difficulty, diarrhoea and vomiting are among the symptoms of Mers.

Dr Subramaniam said Kuala Lumpur would continue to monitor developments in Jeddah and follow suggestions and opinions given by the Saudi Arabian authorities on ways to avoid the infection.

Earlier in his speech, the minister told the audience that the Malaysian healthcare industry was one of the most dynamic and vibrant sectors in the country as it was supported by the private healthcare sector.

Touching on healthcare technology, Dr Subramaniam said it had come into every aspect of daily life, way before the onset of illness.

“In the event of illness, healthcare technology will assist in decision-making and selection of appropriate medical practitioners through a central directory in the wellness data base,” he added.

WHO | WHO issues new HIV recommendations calling for earlier treatment

30 JUNE 2013 | GENEVA – New HIV treatment guidelines by WHO recommend offering antiretroviral therapy (ART) earlier. Recent evidence indicates that earlier ART will help people with HIV to live longer, healthier lives, and substantially reduce the risk of transmitting HIV to others. The move could avert an additional 3 million deaths and prevent 3.5 million more new HIV infections between now and 2025.

The new recommendations are presented in WHO’s “Consolidated guidelines on the use of antiretroviral drugs for treating and preventing HIV infection”, as new data reveal a total of 9.7 million people were taking these lifesaving drugs at the end of 2012.

“These guidelines represent another leap ahead in a trend of ever-higher goals and ever-greater achievements,” says WHO Director-General Dr Margaret Chan. “With nearly 10 million people now on antiretroviral therapy, we see that such prospects – unthinkable just a few years ago – can now fuel the momentum needed to push the HIV epidemic into irreversible decline.”

Call to initiate treatment at 500 CD4 cells/mm³ or less

The new recommendations encourage all countries to initiate treatment in adults living with HIV when their CD4 cell count falls to 500 cells/mm³ or less – when their immune systems are still strong. The previous WHO recommendation, set in 2010, was to offer treatment at 350 CD4 cells/mm³ or less. 90% of all countries have adopted the 2010 recommendation. A few, such as Algeria, Argentina and Brazil, are already offering treatment at 500 cells/mm3.

WHO has based its recommendation on evidence that treating people with HIV earlier, with safe, affordable, and easier-to-manage medicines can both keep them healthy and lower the amount of virus in the blood, which reduces the risk of passing it to someone else. If countries can integrate these changes within their national HIV policies, and back them up with the necessary resources, they will see significant health benefits at the public health and individual level, the report notes.

Further recommendations

The new recommendations also include providing antiretroviral therapy – irrespective of their CD4 count – to all children with HIV under 5 years of age, all pregnant and breastfeeding women with HIV, and to all HIV-positive partners where one partner in the relationship is uninfected. The Organization continues to recommend that all people with HIV with active tuberculosis or with hepatitis B disease receive antiretroviral therapy.

Another new recommendation is to offer all adults starting to take ART the same daily single fixed-dose combination pill. This combination is easier to take and safer than alternative combinations previously recommended and can be used in adults, pregnant women, adolescents and older children.

“Advances like these allow children and pregnant women to access treatment earlier and more safely, and move us closer to our goal of an AIDS-free generation,” said UNICEF Executive Director, Anthony Lake. “Now, we must accelerate our efforts, investing in innovations that allow us to test new born babies faster and giving them the appropriate treatment so that they enjoy the best possible start in life.”

The Organization is further encouraging countries to enhance the ways they deliver HIV services, for example by linking them more closely with other health services, such as those for tuberculosis, maternal and child health, sexual and reproductive health, and treatment for drug dependence.

“The new WHO guidelines are very timely in view of the rapid progress we have made in expanding programmes for prevention and treatment,” says Dr Mark Dybul, Executive Director of the Global Fund to Fight AIDS, Tuberculosis and Malaria. “This is an example of how the Global Fund and the WHO work together to support countries as we move towards removing HIV as a threat to public health.” Since its creation in 2002, the Global Fund has supported more than 1,000 programmes in 151 countries, providing HIV treatment for 4.2 million people.

Challenges remain

Challenges still remain. Alongside the new treatment guidelines, a treatment progress update by WHO, UNAIDS, UNICEF identified areas in need of attention.

While the number of all eligible children on ART has increased by 10% between 2011 and 2012, this is still too slow compared to the 20% increase in adults. A further complication is that many key populations such as people who inject drugs, men who have sex with men, transgender people and sex workers, continue to face legal and cultural barriers that prevent them getting treatment that otherwise would be more easily available. Another factor that needs to be addressed is the significant proportion of people who, for many reasons, ‘drop out’ of treatment.

Data reinforces feasibility of recommendations

Despite this, the Global update on HIV treatment: results, impact and opportunities contains encouraging data that reinforces the feasibility of the new WHO recommendation on earlier ART, which would expand the global number of people eligible for antiretroviral therapy to 26 million.

Between 2011 and 2012, the largest acceleration ever of people enrolled on ART was achieved, with an extra 1.6 million people benefitting from antiretroviral therapy, increasing the total to 9.7 million people. Furthermore, increased coverage of treatment occurred in every region of the world, with Africa leading. Four out of 5 people who started treatment in 2012 were living in sub-Saharan Africa.

“Today nearly 10 million people have access to lifesaving treatment. This is a true development triumph,” says Michel Sidibé, Executive Director of the Joint United Nations Programme on HIV/AIDS (UNAIDS). “But we now have a new challenge – ensuring that all 26 million people eligible for treatment have access – not one person less. Any new HIV infection or AIDS-related death due to lack of access to antiretroviral therapy is unacceptable.”

Today’s recommendations were released by WHO on the opening day of the International AIDS Society 2013 conference in Kuala Lumpur. Among those endorsing the recommendations at the launch were representatives from countries, where such earlier ART intervention is already national policy, along with development agencies who are providing technical and financial support.

The International AIDS Society conference is held every two years and attracts leading scientists, clinicians, public health experts and community leaders to examine the latest developments in HIV-related research, and to explore how scientific advances can inform the global response to HIV/AIDS.

Efforts to promote health face serious challenges from ‘big businesses”, says UN official

KUALA LUMPUR June 11: Global efforts to promote health face serious challenges, including from ‘big businesses’, according to the World Health Organisation WHO director general Dr Margaret Chan.

In a statement on the United Nations’ UN website on June 10, Chan was quoted as saying efforts to promote good health were more vital than ever given that non-communicable diseases have overtaken infectious diseases as the leading cause of death, in her address to the 8th Global Conference on Health Promotion held in Helsinki, Finland.

“Economic growth, modernization, and urbanization have opened wide the entry point for the spread of unhealthy lifestyles,” she was quoted as saying.

She said that getting people to lead healthy lifestyles and adopt healthy behaviours faced opposition from forces that were “not so friendly.”

“Efforts to prevent non-communicable diseases go against the business interests of powerful economic operators. In my view, this is one of the biggest challenges facing health promotion,” she said.

“It is not just Big Tobacco anymore. Public health must also contend with Big Food, Big Soda, and Big Alcohol. All of these industries fear regulation, and protect themselves by using the same tactics,” said Chan.

Chan said these tactics included front groups, lobbies, promises of self-regulation, lawsuits, and industry-funded research that “confuses the evidence and keeps the public in doubt.”

They also include gifts, grants, and contributions to worthy causes that cast these industries as respectable corporate citizens in the eyes of politicians and the public, she added.They include arguments that place the responsibility for harm to health on individuals, and portray Government actions as interference in personal liberties and free choice.

“This is formidable opposition. Market power readily translates into political power. Few Governments prioritize health over big business. As we learned from experience with the tobacco industry, a powerful corporation can sell the public just about anything,” said Chan.

Chan also voiced concern about two recent and related trends.

“The first relates to trade agreements. Governments introducing measures to protect the health of their citizens are being taken to court, and challenged in litigation. This is dangerous,” she stated.

“The second is efforts by industry to shape the public health policies and strategies that affect their products. When industry is involved in policy-making, rest assured that the most effective control measures will be downplayed or left out entirely. This, too, is well documented, and dangerous.

“In the view of WHO, the formulation of health policies must be protected from distortion by commercial or vested interests,” said Chan.

Activists fault WHO report on Fukushima radiation

Activists fault WHO report on Fukushima radiation

 

Activist physicians on Monday accused the World Health Organization of downplaying the health impact of nuclear fallout from the Fukushima nuclear disaster.

In a New York symposium marking the two-year anniversary of the Fukushima nuclear plant meltdown in Japan, the physicians took issue with WHO’s conclusion in a recent report that it did not expect a significant surge in cancer in Japan or elsewhere due to radiation leaks.

“It’s a report that was meant to reassure people who, almost certainly, many will develop leukemia and cancer,” said Helen Caldicott, a prominent anti-nuclear activist whose foundation, the Helen Caldicott Foundation, co-sponsored the symposium, along with Physicians for Social Responsibility.

“What is going to happen is there will be a high incidence of cancer and leukemia and genetic disease,” due to the leaks, she said.

The WHO report drew criticism from Japanese government officials because it projected an increase in some cancers among those living near the plant.

Japanese officials said the report was based on faulty assumptions and would unnecessarily upset residents.

But Caldicott said the report, released Feb 28, understated the problem because of key issues it either “ignored” or “glossed over.”

For one, she said, WHO did not take actual radioactive emissions into account, relying on estimates.

The UN health body also did not examine the effects on children comprehensively, including what the impact would be of eating radiation-contaminated food over a lifetime.

The agency also did not closely examine the impact on workers at the Fukushima plant or on people from the area who evacuated through the plume of radiation that came from the plant, she said.

“As a physician, I abhor what they’ve done,” Caldicott said.

The two-day conference at the New York Academy of Medicine marked the anniversary of the 9.0-magnitude subsea earthquake and tsunami which rocked Japan on March 11, 2011, leaving nearly 15,881 people dead and 2,668 others still unaccounted for.

The quake and tsunami deeply damaged the cooling systems of the Fukushima nuclear plant, causing partial meltdowns in several units and spilling radioctive particles into the air and sea nearby.

Monday’s symposium featured presentations from biologists, epidemiologists and other scientists on the health effects of nuclear accidents.

Caldicott cited one survey done by a Fukushima medical organization that showed 42% of 100,000 children sustained thyroid abnormalities, such as a cyst or a nodule. The survey showed three children with thyroid cancer and seven additional cases of suspected cancer.

She said data showed that three times as much radioactive xenon, and possibly three times as much cesium, escaped at Fukushima as at Chernobyl, the nuclear plant in the Ukraine that released huge amounts of radioactive particles into the atmosphere after an explosion and fire in 1986.

The WHO report did conclude that the cancer risk was higher for certain groups of local people in Fukushima.

That includes a projected 7% increase in leukemia among males exposed as infants, over what would have normally been, and a 6% higher occurrence of breast cancer among women exposed as infants.

The occurrence of thyroid cancer in females over a lifetime could rise by as much as 70% over the normal rate.

But for the general population inside and outside of Japan, the WHO said, “the predicted risks are low and no observable increases in cancer rates above baseline rates are anticipated.”

Steven Starr, a program director at the University of Missouri, presented data from Chernobyl that showed, 14 years later, that 40 percent of high school graduates suffered chronic blood disorders and malfunctioning thyroids.

Starr predicted similar problems in Fukushima.

Maurice Enis and Jaime Plym, two U.S. Navy quartermasters, told the symposium that they experienced the effects of radiation poisoning after servingon a search and rescue mission near Fukushima after the disaster.

Enis complained of loss of energy, hair loss and the appearance of some lumps on his body.

Plym said her menstrual cycle has been thrown off due to exposure to radioactive materials. They said troops were kept in the dark about the severity of the nuclear incident at Fukushima.

The two have joined a lawsuit with 115 current and former U.S. military personnel against the nuclear plant’s owner, Tokyo Electric Power Company, that alleges TEPCO misrepresented the depth of problems at the plant.

針灸有助於緩解花粉熱

【24drs.com】最新研究指出,花粉症患者針灸後症狀可能有些緩解,但這種療法的實際情況仍有待觀察。

研究人員將422位對草和花粉過敏的人隨機分配做12種針灸療程或是對照組,一組接受12次針灸8週,另一組接受「假」針灸,第三組沒有針灸治療。假針灸組是請針灸師使用真的針,但只是插入皮膚而不是傳統的穴位,三組患者在有症狀時都被允許服用抗組織胺藥物。

根據刊載在2月19日內科醫學誌(Annals of Internal Medicine)的研究結果顯示,接受針灸治療的患者症狀改善程度超過對照組。Nelson博士表示,有針灸的人在8週後症狀改善較多,且使用更少抗組織胺藥物治療,他們的生活品質平均進步了0.5到0.7個百分點,這在現實生活中應該轉換成花粉症症狀有明顯差異。

三組針灸的參與者在16週時花粉症的症狀好多了,可能是因為已經過了花粉季節。然而,再8個星期後優點消失。不過,柏林Charite大學醫學中心的Benno Brinkhaus博士表示,這不一定代表針灸沒有好處,他建議對抗過敏藥物沒效或是有副作用而不滿意的患者,可以考慮針灸。

丹佛醫院的過敏症專家HarOLd Nelson博士認為,這篇研究做得很好,而且是正面的,針灸似乎有幫助。但Nelson博士懷疑針灸的時間、不方便、以及費用,特別是有鼻噴劑等更簡單的方法來處理這些症狀,是否還需要去針灸診所坐著插16根針灸20分鐘,而且一個療程要做12次。

Nelson博士指出,鼻噴劑處方含有抗發炎的皮質類固醇,有Flonase和Nasonex等品牌,每天噴有助於防止花粉症狀。這篇研究中的患者未使用鼻噴劑,他們服用抗組織胺,但這並不是最有效的方式。不過,或許有人不想服用藥物,所以對針灸感興趣。

許多研究指出,中醫針灸是透過刺激皮膚上某些穴點,認為這樣可以影響能量或氣的流動。針灸有助於緩解偏頭痛或背痛等各類疼痛,以及治療與手術或化療相關的噁心和嘔吐。

杜克大學醫學院的Rem Coeytaux表示,當然,如果有興趣不妨一試。這篇研究的優點是將針灸與抗組織胺藥物和假針灸進行比較,假針灸是為了讓患者有「安慰劑效應」,感覺自己有被治療而感覺好多了,但可能真的具有生理效應,使得假治療成為不良的安慰劑。

美國,大部分州都要求針灸師需領有執照,有些想嘗試針灸的花粉症患者住家附近可能沒有很多執業者。針灸的價格也各不相同,通常是一次100美元左右,而且醫療保險通常不包含。

Nelson博士表示,若想用自然的方法來擺脫花粉症痛苦,也可以考慮打抗過敏針,也就是打一系列的針避免接觸到會誘發過敏的物質時發作,並訓練免疫系統的耐受性。
