Diagnosis and treatment delay among pulmonary tuberculosis patients identified using the Taiwan reporting enquiry system, 2002–2006
Hui-Ping Lin, Chung-Yeh Deng, Pesus Chou
BMC Public Health , 2009, DOI: 10.1186/1471-2458-9-55
Abstract: A total of 114,827 cases were reported using the Taiwan enquiry system between 2002 and 2006; of these, 26,027 (22.7%) were finally diagnosed as not being tuberculosis, 7,005 (8.2%) were diagnosed as extra-pulmonary tuberculosis and 3,677 (3.2%) were not a first-time diagnosis of tuberculosis, and these cases were hence excluded. Diagnosis time was defined as the length of time between the first medical examination (including chest radiography, sputum smear or sputum culture) to the diagnosis of PTB; treatment time was defined as the period from the diagnosis of PTB to the initiation of treatment. Using the cut-off at the 75th percentile, a period of longer than 9 days was defined as a diagnosis delay and a period of longer than 2 days as a treatment delay. Multiple logistic regression analysis was applied to analyze the risk factors associated with these delays.During the five-year study period, among the 78,118 new PTB patients reported in Taiwan, the mean diagnosis and treatment times were 12 and 5 days and the median times 1 day and 0 days, respectively. In total, 24.9% of the new PTB patients' diagnosis time delays were longer than 9 days and 20.3% of the patients' treatment time delays were longer than 2 days. The main factors associated with diagnosis delay included age, reporting year, living with family and a positive sputum culture (p < 0.0001); the risk factors significantly associated with treatment delay were increased age, an aboriginal ethnic background, a positive sputum culture and diagnosis at a non-medical center (p < 0.0001).The Taiwan TB reporting enquiry system has successfully increased the confirmed PTB reporting rate from 64.4% to 71.5%. Greater age and a positive sputum culture were both found to significantly increase both diagnosis and treatment delays; treatment delay is also significantly affected by the patient having an aboriginal ethnic background and being diagnosed at a non-medical center.Diagnosis and treatment delay of tuberculos

BMC Health Services Research , 2009, DOI: 10.1186/1472-6963-9-10
Abstract: This study applied a cross-sectional survey design. A total of 207 white-collar foreign workers of a non-Asian background currently holding National Health Insurance cards who had lived in Taiwan for 4 months or more participated in this study.The prevalence of TCM use was 45%. The most frequently used therapies were traditional Chinese herbs/medicine and acupuncture. Factors indicating the likelihood of TCM usage were age 31–40 years, visit to an allopathic medical doctor in the last year, ability to read Chinese, having a friend or family member available to assist in the use of TCM, and access to information about TCM services available in Taiwan.Utilization of TCM by people of a non-Asian background living in Taiwan appears to be most influenced by enabling factors including language ability, access to information, and informal reference persons.Taiwan, a modern Chinese country, has a National Health Insurance Scheme (NHIS) that provides coverage of general medical expenses to virtually all of its citizens and foreign workers [1]. Included in the NHIS are both modern allopathic medical care and traditional Chinese medicine (TCM). Although allopathic medicine is more predominant, over 3,700 licensed doctors of TCM practice in 2,500 hospitals and clinics around the country [1]. Patients are free to choose any health care provider registered under the NHIS for their care, without the need for approval by a gatekeeper.The number of foreign residents in Taiwan has increased from 30,000 in 1991 to almost 293,000 in 2005 [2]. Much of this population is South East Asian but a significant number, around 15%, are professional/skilled or white collar workers from the United States, Australia, Canada and Europe [3]. There have been few studies of non-Asian foreign workers living in Taiwan and little is known about how this high level of TCM availability is accessed and used by this population. Previous studies about TCM utilization were mostly among people with a Chinese et
Directly Observed Therapy Reduces Tuberculosis-Specific Mortality: A Population-Based Follow-Up Study in Taipei, Taiwan
Yung-Feng Yen, Muh-Yong Yen, Yi-Ping Lin, Hsiu-Chen Shih, Lan-Huei Li, Pesus Chou, Chung-Yeh Deng
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0079644
Abstract: Objectives To determine the effect of directly observed therapy (DOT) on tuberculosis-specific mortality and non-TB-specific mortality and identify prognostic factors associated with mortality among adults with culture-positive pulmonary TB (PTB). Methods All adult Taiwanese with PTB in Taipei, Taiwan were included in a retrospective cohort study in 2006–2010. Backward stepwise multinomial logistic regression was used to identify risk factors associated with each mortality outcome. Results Mean age of the 3,487 patients was 64.2 years and 70.4% were male. Among 2471 patients on DOT, 4.2% (105) died of TB-specific causes and 15.4% (381) died of non-TB-specific causes. Among 1016 patients on SAT, 4.4% (45) died of TB-specific causes and 11.8% (120) died of non-TB-specific causes. , After adjustment for potential confounders, the odds ratio for TB-specific mortality was 0.45 (95% CI: 0.30–0.69) among patients treated with DOT as compared with those on self-administered treatment. Independent predictors of TB-specific and non-TB-specific mortality included older age (ie, 65–79 and ≥80 years vs. 18–49 years), being unemployed, a positive sputum smear for acid-fast bacilli, and TB notification from a general ward or intensive care unit (reference: outpatient services). Male sex, end-stage renal disease requiring dialysis, malignancy, and pleural effusion on chest radiography were associated with increased risk of non-TB-specific mortality, while presence of lung cavities on chest radiography was associated with lower risk. Conclusions DOT reduced TB-specific mortality by 55% among patients with PTB, after controlling for confounders. DOT should be given to all TB patients to further reduce TB-specific mortality.

Clustering-Inverse: A Generalized Model for Pattern-Based Time Series Segmentation  [PDF]
Zhaohong Deng, Fu-Lai Chung, Shitong Wang
Journal of Intelligent Learning Systems and Applications (JILSA) , 2011, DOI: 10.4236/jilsa.2011.31004
Abstract: Patterned-based time series segmentation (PTSS) is an important task for many time series data mining applications. In this paper, according to the characteristics of PTSS, a generalized model is proposed for PTSS. First, a new inter-pretation for PTSS is given by comparing this problem with the prototype-based clustering (PC). Then, a novel model, called clustering-inverse model (CI-model), is presented. Finally, two algorithms are presented to implement this model. Our experimental results on artificial and real-world time series demonstrate that the proposed algorithms are quite effective.

Po-Ching Chi, Chi-In Lo, Charles Jia-Yin Hou, Hung-I Yeh, Chung-Lieh Hung
Case Reports in Clinical Medicine (CRCM) , 2013, DOI: 10.4236/crcm.2013.24072
Abstract:

Pericarditis and hemopericardium causing cardiac tamponade, caused by large and transmural ventricular infarction with subsequent rupture into the pericardium, is a rare complication post acute myocardial infarction. This is frequently fatal with rapid clinical course. We reported a 65-year-old female who presented with persistent diaphoresis and dyspnea for several hours followed by syncope. Acute myocardial infarction was diagnosed with primary percutaneous coronary intervention performed though persistent hypotension was observed. Moderate amount of hemopericardium leading to tamponade was found. It was relieved after pericardiocentesis. Real-time three-dimensional echocardiography revealed blood clot with specific whirling pattern around the infracted ventricular wall with suspected leak.

GIS-Based Regionalization of LCA  [PDF]
Kevin Fong-Rey Liu, Ming-Jui Hung, Po-Chung Yeh, Jong-Yih Kuo
Journal of Geoscience and Environment Protection (GEP) , 2014, DOI: 10.4236/gep.2014.22001
Abstract: Although LCA is normally not focused on the local impacts for a product system, but when LCA is applied to other environmental system analysis tools the local impact may be important, such as the Strategic Environmental Assessment (SEA). In this study, the regionalization of LCA refers to the conversion of the results from site-generic or site-dependent LCIAs into smaller spatial units. The regionalization of LCAs is achieved by a geographic information system (GIS). GIS can easily allocate the impact into smaller spatial units through the overlay analysis of fate, exposure and effect layers.
Estimation of River Pollution Index in a Tidal Stream Using Kriging Analysis
Yen-Chang Chen,Hui-Chung Yeh,Chiang Wei
International Journal of Environmental Research and Public Health , 2012, DOI: 10.3390/ijerph9093085
Abstract: Tidal streams are complex watercourses that represent a transitional zone between riverine and marine systems; they occur where fresh and marine waters converge. Because tidal circulation processes cause substantial turbulence in these highly dynamic zones, tidal streams are the most productive of water bodies. Their rich biological diversity, combined with the convenience of land and water transports, provide sites for concentrated populations that evolve into large cities. Domestic wastewater is generally discharged directly into tidal streams in Taiwan, necessitating regular evaluation of the water quality of these streams. Given the complex flow dynamics of tidal streams, only a few models can effectively evaluate and identify pollution levels. This study evaluates the river pollution index (RPI) in tidal streams by using kriging analysis. This is a geostatistical method for interpolating random spatial variation to estimate linear grid points in two or three dimensions. A kriging-based method is developed to evaluate RPI in tidal streams, which is typically considered as 1D in hydraulic engineering. The proposed method efficiently evaluates RPI in tidal streams with the minimum amount of water quality data. Data of the Tanshui River downstream reach available from an estuarine area validate the accuracy and reliability of the proposed method. Results of this study demonstrate that this simple yet reliable method can effectively estimate RPI in tidal streams.
A Polygon Model for Wireless Sensor Network Deployment with Directional Sensing Areas
Chun-Hsien Wu,Yeh-Ching Chung
Sensors , 2009, DOI: 10.3390/s91209998
Abstract: The modeling of the sensing area of a sensor node is essential for the deployment algorithm of wireless sensor networks (WSNs). In this paper, a polygon model is proposed for the sensor node with directional sensing area. In addition, a WSN deployment algorithm is presented with topology control and scoring mechanisms to maintain network connectivity and improve sensing coverage rate. To evaluate the proposed polygon model and WSN deployment algorithm, a simulation is conducted. The simulation results show that the proposed polygon model outperforms the existed disk model and circular sector model in terms of the maximum sensing coverage rate.
