Doctors called for greater public awareness of COPD -- chronic obstructive pulmonary disease -- following the launch of World COPD Day at a press conference yesterday.
"Nov. 20 is World COPD Day," said Shiao Guang-ming (
"A study by the World Bank and World Health Organization estimated that COPD is expected to rise to number five in terms of deaths by the year 2020," Shiao said.
Shiao's report revealed that in the 19 years between 1981 to 2000, the death rate for COPD in Taiwan increased by 11.66 percent annually.
"The fast increase in the COPD death rate comes as quite a surprise," said Shiao.
COPD is a progressive respiratory disease that produces a decline in lung function that is not fully reversible. The loss of lung function and and reduction of airflow is associated with an abnormal inflammatory response of the lungs to certain noxious particles or gases.
"To awaken global awareness of the disease, experts and organizations from more than 100 countries decided the theme for this year's World COPD Day is `Raise COPD Awareness Worldwide'," Shiao said.
"Many major medical associations together have launched the Global Initiative for Chronic Obstructive Lung Disease to combat the disease," said Luh Kwen-tay (
The program is chiefly led by the US National Heart, Lung, and Blood Institute and the WHO, Luh said.
"The characteristic symptoms of COPD -- cough, sputum production and shortness of breath on exertion -- often precede the development of COPD by many years," Shiao warned.
Emphysema and chronic bronchitis are two distinct types of COPD. Some asthmatics also have permanently narrowed airways and suffer from COPD, Shiao said.
COPD is actually a broad term that covers several lung and respiratory diseases.
As the disease is difficult to detect in the initial stages, the Taiwan Society of Pulmonary and Critical Care Medicine (TSPCCM) provided a questionnaire for people to answer to help them determine whether they are prone to the disease.
The questionaire contained five yes or no questions:
1. Do you often cough?
2. Do you often have sputum production?
3. Do you breath more laboriously than other people of your age?
4. Are you over the age of 40?
5. Are you a smoker (or were you a smoker)?
Shaio said that if people answer `yes' to more than three questions, they should go immediately for a breathing test at the hospital.
"The earlier you discover the disease, the less damage your lungs will suffer," he said.
Shiao pointed out that smoking is the major cause of COPD. In fact, according to the WHO, 75 percent of deaths from COPD that occur in developed countries are directly related to cigarette smoking and tobacco.
"To avoid the disease, the primary thing is to stop smoking," Shiao said.
Shiao suggested that the government should take measures to improve air quality, strengthen COPD-related research, take better care of people's living environments and develop medical technologies related to COPD.
An essay competition jointly organized by a local writing society and a publisher affiliated with the Chinese Communist Party (CCP) might have contravened the Act Governing Relations Between the People of the Taiwan Area and the Mainland Area (臺灣地區與大陸地區人民關係條例), the Mainland Affairs Council (MAC) said on Thursday. “In this case, the partner organization is clearly an agency under the CCP’s Fujian Provincial Committee,” MAC Deputy Minister and spokesperson Liang Wen-chieh (梁文傑) said at a news briefing in Taipei. “It also involves bringing Taiwanese students to China with all-expenses-paid arrangements to attend award ceremonies and camps,” Liang said. Those two “characteristics” are typically sufficient
A magnitude 5.9 earthquake that struck about 33km off the coast of Hualien City was the "main shock" in a series of quakes in the area, with aftershocks expected over the next three days, the Central Weather Administration (CWA) said yesterday. Prior to the magnitude 5.9 quake shaking most of Taiwan at 6:53pm yesterday, six other earthquakes stronger than a magnitude of 4, starting with a magnitude 5.5 quake at 6:09pm, occurred in the area. CWA Seismological Center Director Wu Chien-fu (吳健富) confirmed that the quakes were all part of the same series and that the magnitude 5.5 temblor was
The brilliant blue waters, thick foliage and bucolic atmosphere on this seemingly idyllic archipelago deep in the Pacific Ocean belie the key role it now plays in a titanic geopolitical struggle. Palau is again on the front line as China, and the US and its allies prepare their forces in an intensifying contest for control over the Asia-Pacific region. The democratic nation of just 17,000 people hosts US-controlled airstrips and soon-to-be-completed radar installations that the US military describes as “critical” to monitoring vast swathes of water and airspace. It is also a key piece of the second island chain, a string of
The Central Weather Administration has issued a heat alert for southeastern Taiwan, warning of temperatures as high as 36°C today, while alerting some coastal areas of strong winds later in the day. Kaohsiung’s Neimen District (內門) and Pingtung County’s Neipu Township (內埔) are under an orange heat alert, which warns of temperatures as high as 36°C for three consecutive days, the CWA said, citing southwest winds. The heat would also extend to Tainan’s Nansi (楠西) and Yujing (玉井) districts, as well as Pingtung’s Gaoshu (高樹), Yanpu (鹽埔) and Majia (瑪家) townships, it said, forecasting highs of up to 36°C in those areas
