Abstract Background Comorbid conditions influence the survival of cancer patients. This study evaluated the influence of comorbidity on survival among lung cancer patients. Methods The authors evaluated the medical records of 1111 lung cancer patients of a medical center in Taiwan. Days of survival were calculated for each patient and mortality hazard ratios were estimated for associations with demographic status, comorbidity and cancer stage at diagnosis. Results On average, the survival time was slightly longer among women than among men (838 ± 689 vs. 749 ± 654 days, p = 0.050). Survival days increased with age (from 580 ± 526 [≤ 50 years] to 803 ± 693 [≥ 71 years] days, p = 0.020) and decreased with stage (from 1224 ± 656 [stage I] to 489 ± 536 [stage IV] days, p p = 0.002) and a higher mortality hazard ratio (1.30, 95% CI: 1.03 - 1.65). A similar trend was observed in lung cancer patients with diabetes. Conclusions Lung cancer patients with comorbid tuberculosis or diabetes are at an elevated risk of mortality. These patients deserve greater attention while undergoing cancer treatment.

- Abstract
Aim: This study investigated the levels of depression and anxiety in nurses and nursing assistants working in long-term care facilities during the COVID-19 pandemic. We also explored the potential causes of depression and anxiety in nurses and nursing assistants working in long-term care facilities during the pandemic., Background: The COVID-19 pandemic has had a considerable impact on long-term care facilities. The high infection and mortality rates for COVID-19 have resulted in an increased workload for caregivers., Introduction: The COVID-19 pandemic exposed caregivers working in long-term care facilities to higher risks of anxiety and depression. Additionally, the high risk of infection in the work environment and concerns about spreading COVID-19 to family members and long-term care facility residents led to various forms of stress among caregivers., Methods: The present study was a cross-sectional study. Questionnaires were used to investigate depression and anxiety among regarding nurses and nursing assistants working in long-term care facilities during the pandemic., Results: The depression and anxiety levels of the nurses were higher than nursing assistants, but had no statistically significant difference (p = 0.551). The factors influencing levels of depression and anxiety in nurses contained facility affiliation and experience working. In terms of nursing assistants, age, marital status, and facility affiliation were correlated with the levels of depression and anxiety., Discussion: The pandemic has severely impacted caregivers. In the process of implementing pandemic prevention measures and providing care for COVID-19 patients, safeguarding the psychological health of caregivers is also essential., Conclusion: The levels of depression and anxiety in nurses were higher than in nursing assistants working in long-term care facilities during the pandemic., Implication for Nursing and Health Policy: Long-term care facilities managers are recommended to enhance the education and training process for caregivers. Managers are also recommended to ensure provision of sufficient amounts of pandemic prevention equipment and resources., (© 2024 International Council of Nurses.)

- Abstract
A universal health insurance program such as the National Health Insurance in Taiwan offers a wide coverage and increased access to healthcare services. Despite its ongoing efforts to enhance healthcare accessibility, differences in health for people living in urban and resource-deprived areas remain substantial. To investigate the longitudinal impact of the healthcare system and other potential structural drivers such as education and economic development on geographical disparities in health, we designed a panel study with longitudinal open secondary data, covering all 368 townships in Taiwan between 2013 and 2017. Our findings indicated higher mortality rates in the mountainous and rural areas near the east and south regions of the island in both years. Multivariate analyses showed an increase in the density of primary care physicians (PCP) was associated with lower all-cause mortality (β = - 0.72, p < 0.0001) and cardiovascular disease mortality (β = - 0.41, p < 0.0001). Effect of PCP is evident, but merely focusing on access to healthcare is still not enough. Additional measures are warranted to address the health disparities existing between urban and underprivileged areas., (© 2023. Springer Nature Limited.)

- Abstract
Objectives: Patients with terminal cancer often experience physical and mental distress. Signing a do-not-resuscitate order (DNR) is crucial to protect against invalid treatment. This study aims to explore the effect of hospice shared care intervention by medical staff on the completion of a DNR-S (DNR order signed by surrogates) for patients with terminal cancer., Method: The cross-sectional study in this research involved secondary analysis of data from the 2011-2015 clinical cancer case management database of a medical center in central Taiwan. Those with a DNR order signed by patients (DNR-P) or DNR-S before the hospice shared care consultation were excluded from this study; a total of 1,306 patients with terminal cancer were selected., Results: This study demonstrated that the percentage of DNR-S after consultation involving both nurse and physician was 75.4%. With other variables controlled, the number of DNR-Ss after consultation with a nurse was significantly lower [odds ratio (OR) = 0.57, 95% confidence interval (CI) = 0.42-0.75] and that of DNR-Ss after consultation involving both nurse and physician was significantly higher (OR = 1.35, 95% CI = 1.01-1.79), than that of DNR-Ss after consultation with only the physician., Significance of Results: Joint involvement of the nurse and physician in hospice care provides sufficient information to patients and family with terminal cancer about their condition and enhances doctor-patient communication. This effectively assists patients with terminal cancer and their family members in making the major decision of signing a DNR, alleviates the concerns of patients and family members about signing a DNR, and reduces terminal cancer patients' pain at the end of life to ensure that they die in peace and dignity.

- Abstract
Background: Studies comparing mental disorder risks between women with breast cancer and cervical cancer are lacking. This study compared risks of developing anxiety and depression between women with breast cancer (BC cohort) and women with cervical cancer (CC cohort) using insurance claims data of Taiwan., Methods: From the 2000 to 2016 data, we identified a BC cohort and BC controls (N = 96,862) and a CC cohort and CC controls (N = 26,703), matched by propensity scores. Incident mental disorders and the Cox method estimated the related cancer cohort to control cohort hazard ratios (HRs), and 95% confidence intervals (CIs) were estimated by the end of 2016., Results: Compared to the CC cohort, the BC cohort had slightly higher incident anxiety (15.9 versus 15.5 per 1,000 person-years) and depression (6.92 vs. 6.28 per 1,000 person-years). These mental disorders were higher in respective cancer cohorts than controls. The BC cohort to BC control adjusted HRs of anxiety and depression were 1.29 (95% CI = 1.25-1.33) and 1.78 (95% CI = 1.69-1.87), respectively. The corresponding adjusted HRs for the CC cohort were 1.12 (95% CI = 1.06-1.18) and 1.29 (95% CI = 1.18-1.41). The combined incidence rates of both disorders were 1.4-fold greater in the BC cohort than in BC controls (22.8 vs. 15.8 per 1,000 person-years), and 1.2-fold greater in the CC cohort than in the CC controls (21.7 vs. 18.3 per 1,000 person-years)., Conclusion: Women with breast cancer or cervical cancer are at an elevated likelihood of developing anxiety and depression disorders. These incident disorders are slightly higher in those with breast cancer., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Yang, Sung, Mou, Liao, Wang and Shieh.)

- Abstract
Background: The association between ambient air pollution (AAP) and the risk of Rheumatoid arthritis (RA) remains debatable. We conducted a population-based cohort study to investigate the association between exposure to AAP and the risk of RA in Taiwan. Methods: We analyzed and combined the longitudinal Health Insurance Database (LHID) and the Taiwan Air Quality-Monitoring Database (TAQMD), which were in line with the residential areas. We calculated the RA incidence rates per 10,000 person-years exposed to each quartile of PM2.5 or PM10 concentrations or RH. Hazards regression was conducted to analyze the associations between exposure to each quartile of PM2.5 and PM10 concentrations and the risk of developing RA. The hazard ratios of RA were analyzed between participants exposed to annual average concentrations of PM2.5 and PM10. All the hazard ratios of RA were stratified by gender and adjusted for age and relative humidity (RH). A p-value < 0.05 was considered statistically significant. Results: Among 722,885 subjects, 9338 RA cases were observed. The analyses adjusted for age, gender, and humidity suggested an increased risk of developing RA in the exposure to PM2.5 in the last quartile (Q4) with the adjusted hazard ratio (aHR) was 1.053 (95%CI: 1.043 to 1.063). Conclusion: Our study suggests that exposure to PM2.5 is associated with an increased risk of RA. The finding has implications for policymaking to develop coping strategies to confront AAP as a risk factor for RA.

- Abstract
Using the claims data of one million insured residents in Taiwan from 1996-2013, this study identified 12,126 women in an urban city (Taichung) and 7229 women in a rural county (Yunlin), aged 20 and above. We compared Papanicolaou (Pap) test uses and cervical cancer detection rates between urban and rural women. Results showed that the Pap screening rate was slightly higher in rural women than in urban women (86.1 vs. 81.3 percent). The cervical cancer incidence was much greater for women without Pap test than women with the test (35.8 vs. 9.00 per 1000 in rural women and 20.3 vs. 7.00 per 1000 in urban women). Nested case-control analysis showed that Pap test receivers had an adjusted odds ratio (OR) of 0.35 (95% CI = 0.25-0.51) to be diagnosed with cervical cancer as compared to those who did not receive the test. The rural women had an adjusted OR of 1.46 (95% CI = 1.03-2.06) to be diagnosed with cervical cancer as compared to urban women. In conclusion, women in rural area are at higher cancer risk than city women. Women who do not undergo Pap tests deserve timely intervention of Pap test to prevent the onset of cancer, particularly in rural women with low income.

- Abstract
With the increasing number of people with disabilities caused by an aging global population, the need for long-term care is gradually increasing. Nursing assistants (NAs) are the primary providers of direct care services to older adults with disabilities, whose knowledge, skills, and beliefs affect the quality of care provided. This study aimed to investigate the influential factors affecting NAs' current competences. A total of 255 NAs' valid questionnaires were collected from 20 long-term care institutions in Taiwan through convenience sampling. The questionnaire comprised dimensions of demographics and care competence. The study results indicated that NAs had the greatest care competence in the domain of recognition of patient rights (4.64 ± 0.54 points). The multiple regression indicated that age, religion, job category, disability care experience, the receiving of performance bonuses, and the receiving of year-end bonuses significantly affected the level of care competence ( p < 0.05). With the aforementioned findings, the results of this study serve as references for the government in employing long-term care NAs and developing management policies. Training programs for NAs should be developed to improve the quality of care provided to older adults with disabilities.

- Abstract
Objective: Taiwan is projected to become a super-aged society in 2026. Taiwan's government introduced an innovative preventive care policy to improve aging-related conditions in 2017. In this study, we examine the effectiveness of an eating ability promotion program (EAPP) on the physical and mental performance of community-dwelling older adults., Design: Single-masked, cluster randomized trial., Setting: Two community care stations in Taichung, Taiwan., Participants: Volunteers were recruited from these 2 community care stations. The 70 participants were aged ≥60 years, able to walk independently and take care of themselves, and understood Mandarin or Taiwanese., Intervention: The volunteers were randomly assigned to an intervention; 40 participated in EAPP training courses (experimental group) and 30 participated in originally scheduled activities only (control group). EAPP training courses were conducted in the care stations 4 hours per week for 12 weeks (for a total of 48 hours)., Measures: The physical performance outcomes were oral health, nutritional status, and fragility, assessed using the Oral Health Assessment Tool, the Mini Nutritional Assessment, and the Study of Osteoporotic Fractures fragility index, respectively. Cognitive function was evaluated with the Mini-Cog test. Measurements were performed at baseline, at the end of the 12-week intervention, and 1 month later., Results: Following the EAPP intervention, controlling for baseline differences, the oral health (F = 33.29, P < .001), nutritional status (F = 7.30, P = .009), and scale of fragility (F = 19.05, P < .001) of the participants in the experimental group were significantly better than those reported in the control group., Conclusions and Implications: Results of this preliminary study suggest that the EAPP intervention may be an effective approach for improving oral health, nutritional status, and fragility in community-dwelling older adults. This training course, which provides clear and concise information regarding eating ability strategies, should undergo further evaluation and, if demonstrated to be effective and cost-effective in broader trials, may be useful in promoting healthy living., (Copyright © 2020 AMDA – The Society for Post-Acute and Long-Term Care Medicine.

- Abstract
Background: Oral hygiene is often neglected in clients receiving long-term care, suggesting that long-term care workers require formal oral hygiene education. Thus, the aim of this study was to investigate the effects of oral hygiene education on long-term care workers., Methods: This study utilized a mixed methods design. Eighty long-term care workers were recruited for participation in the oral hygiene education program, which employed three teaching methods: narration with multimedia presentation, demonstration, and teach-back. The effect of the education program on the participants' level of oral hygiene knowledge, attitudes, and skills was measured using a structured questionnaire that was administered both pre- and post-delivery of the education program. Three months later, all participants submitted a self-report of their oral hygiene skills, and six participants completed a telephone interview. Quantitative data were analyzed using paired t -tests, and qualitative data were manually analyzed and coded., Results: Scores of oral hygiene knowledge ( p < 0.001), attitudes ( p = 0.001), and oral cleaning daily frequency for clients ( p < 0.001), were significantly higher three months after undertaking the educational program., Conclusions: This preliminary study suggests that oral hygiene education may be effective in improving oral hygiene knowledge, attitudes, and skills among long-term care staff.

- Abstract
Background: Population ageing is a worldwide phenomenon that could influence health policy effectiveness. This research explores the impact of age structural transitions on copayment policy responses under Taiwan's National Health Insurance (NHI) system., Methods: The time-varying parameter vector autoregressive model was applied to create two measures of the copayment policy effectiveness, and multiple linear regression models were used to verify the nonlinear effect of age structural transitions on copayment policy responses., Results: Our results show that copayment policy effectiveness (in terms of the negative response of medical center outpatient visits to upward adjustments in copayment) is positively correlated with the proportions of the population in two older age groups (aged 55-64 and ≥ 65) and children (age < 15), but negatively correlated with the proportion of the population that makes up most of the workforce (aged 15‒54). These tendencies of age distribution, which influence the responses of medical center outpatient visits to copayment policy changes, predict that copayment policy may have a greater influence on medical center outpatient utilization in an ageing society., Conclusions: Policymakers should be concerned about the adverse effects of copayment adjustments on the elderly, such as an increasing financial burden and the effect of pricing some elderly patients out of Taiwan's NHI system.

- Abstract
This study examined unmet supportive care needs for nasopharyngeal carcinoma (NPC) patients by cancer stage and treatment phase, as well as the factors associated with these unmet needs. At a cancer center in central Taiwan, information on consultations and services patients received at the resource center was described in the service chart. We extracted data available for NPC patients to evaluate their unmet supportive care needs (health information, patient care, treatment, nutritional, psychosocial, and economic) and their association with sex, age, cancer stage, and treatment phase. The 145 NPC patients were 68.3% male, 60.0% less than 50 years old, and 83.5% diagnosed at stages III and IV. The most prevalent unmet need was nutritional (40.7%), followed by psychosocial and patient care, with economic unmet needs the least (4.8%). Women were more likely than men to have patient care unmet needs (32.6% vs. 15.2%). Nutritional unmet need was higher in older patients than in younger ones (83.3% vs. 35.6%), with an adjusted odds ratio (aOR) of 9.39 (95% confidence interval (CI) = 2.17-40.70). Psychosocial unmet needs were higher in younger patients than old patients (34.5% vs. 0%) and in patients interviewed during follow-up period than those at newly diagnosed (55.2% vs. 23.1%). In conclusion, the most commonly reported concern was nutritional unmet needs for NPC patients. Their unmet needs may vary by demographic and disease factors, including patient sex and age, cancer stage, and treatment phase.

- Abstract
Pemphigus is a chronic dermatological disorder caused by an autoimmune response and is associated with a high proportion of comorbidities and fatalities. The aim of this study was to investigate the risk of depression in patients with pemphigus. Data were derived from the National Health Insurance Research Database recorded during the period 2000-2010 in Taiwan. Multivariate Cox proportional hazards regression models were used to analyze the data and assess the effects of pemphigus on the risk of depression after adjusting for demographic characteristics and comorbidities. Patients with pemphigus were 1.98 times more likely to suffer from depression than the control group (pemphigus, adjusted HR: 1.99, 95% CI = 1.37-2.86). People aged ≥65 years were 1.69 times more likely to suffer from depression than those aged 20-49 years (≥65 years, adjusted HR: 1.42, 95% CI = 0.92-2.21). Female and male patients with pemphigus were respectively 2.02 and 1.91 times more likely to suffer from depression than the control group (female, adjusted HR: 2.09, 95% CI = 1.24-3.54; male, adjusted HR: 1.87, 95% CI = 0.97-3.60). People with HTN, hyperlipidemia, asthma/COPD, and chronic liver disease were respectively 1.73, 2.3, 2.2, and 1.69 times more likely to suffer from depression than those without these comorbidities (HTN, adjusted HR: 0.75, 95% CI = 0.41-1.42; hyperlipidemia, adjusted HR: 1.48, 95% CI = 0.78-2.82; asthma/COPD, adjusted HR: 1.4, 95% CI = 0.72-2.69; and chronic liver disease, adjusted HR: 1.61, 95% CI = 1.07-2.43). There was a significant association between pemphigus and increased risk of depression. Female patients had a higher incidence of depression., Competing Interests: The authors declare no conflict of interest.

- Abstract
Objective: This study aimed to examine the differences between patients with breast cancer (BC) at different cancer stages and treatment phases in terms of unmet supportive care needs as well as to predict the critical factors that influence the unmet needs of such patients., Materials and Methods: A retrospective study was conducted by collecting data from the case consultation and service records of a cancer center in central Taiwan. Information extracted from the case consultation and service records included patients' age, treatment phase, cancer stage, and unmet need domains., Results and Conclusion: Overall, 1129 BC patients were recruited. In the prediction of critical factors influential to the health information needs of patients with BC, in-treatment patients, and those undergoing a follow-up were found to have significantly lower health information needs than patients newly diagnosed with BC. In-treatment and follow-up patients had significantly lower patient care needs than those newly diagnosed with BC. Stage II, III, and IV BC patients had significantly lower nutritional needs than stage I patients. In-treatment patients and those receiving follow-ups had significantly lower nutritional needs than patients newly diagnosed with BC. Relapse and terminal care patients had significantly higher psychosocial needs than patients newly diagnosed with BC. Thus, unmet needs of patients with cancer differ according to their age, cancer stage, and treatment phase. Appropriate and punctual tailored support provided by medical care personnel to address the unmet needs of patients can reduce the unmet supportive care needs in such patients and improve the quality of medical care services they are provided with. Ultimately, the overall quality of life of patients can be improved., Competing Interests: Declaration of Competing Interest There are no conflicts of interest to declare., (Copyright © 2020.

- Abstract
The use of functional information in the form of species traits plays an important role in explaining biodiversity patterns and responses to environmental changes. Although relationships between species composition, their traits, and the environment have been extensively studied on a case-by-case basis, results are variable, and it remains unclear how generalizable these relationships are across ecosystems, taxa and spatial scales. To address this gap, we collated 80 datasets from trait-based studies into a global database for metaCommunity Ecology: Species, Traits, Environment and Space; "CESTES". Each dataset includes four matrices: species community abundances or presences/absences across multiple sites, species trait information, environmental variables and spatial coordinates of the sampling sites. The CESTES database is a live database: it will be maintained and expanded in the future as new datasets become available. By its harmonized structure, and the diversity of ecosystem types, taxonomic groups, and spatial scales it covers, the CESTES database provides an important opportunity for synthetic trait-based research in community ecology.

- Abstract
Objective: To describe cervical cancer screening participation among women in Taiwan under its population-based screening policy and to estimate the economic burden of disease attributable to avoidable disparities in cervical cancer (CC) screening., Methods: We identified a nationally-representative sample of females aged 30 years or above who were eligible for Pap smear testing in Taiwan from 1 January to 31 December 2013. An administrative database with detailed claims of health care utilization under the universal coverage health care system was used. Socioeconomic position of the female subjects was defined using the occupation classification, and two groups were specifically identified: general (O1) and low-income (O5) groups. Differences in screening rate, CC prevalence, and CC-attributable deaths were assessed between the two groups. Economic consequences as a result of screening inequalities were estimated using actual total health care spending (health care expenditure), monetary value per life-year and years of life lost for ill health and screening disparities (health as consumption good), and productivity losses alongside costs of social benefits (health as capital good)., Result: A total of 301,057 enrolled females aged 30 years and older eligible for screening were identified. Overall, 3-year and 1-year screening rates among all subjects were 0.601 and 0.372, respectively. Impact of observed differences in screening translated to US$59,568 of health care spending in one year, 90.4% of which was specific to hospital admissions. When we viewed health as a consumption good and capital good, the impact of screening disparity on health losses through CC would be equivalent to US$78,095 and US$190,868, respectively., Conclusion: Forgone health and economic benefits associated with inequalities in CC screening uptake can be considerable in productive women.

- Abstract
Debates regarding the most beneficial medical or surgical procedures for patients with spontaneous intracerebral hemorrhage (sICH) are still ongoing. We aimed to evaluate the risk of subsequent vascular disease and mortality in patients with sICH treated with and without surgical intervention, in a large-scale Asian population. Patients hospitalized within 2000 to 2013 who were newly diagnosed with sICH were identified using the National Health Insurance Research Database of Taiwan. Neuroendoscopy and craniotomy groups comprised patients who underwent surgical treatment within 1 week, while those in the control group did not undergo early surgical treatment. Outcomes included subsequent hemorrhagic and ischemic stroke, following acute myocardial infarction, congestive heart failure, and mortality. After propensity score matching, there were 663 patients in each group. Compared to that in the control group, the neuroendoscopy and craniotomy groups had a significantly higher risk of secondary vascular events at 1 to 3 months of follow-up (adjusted HR, 2.08 and 1.95; 95% CI, 1.21-3.58 and 1.13-3.35; p < 0.01 and p < 0.05, respectively), but a significantly lower risk after 3 years of follow-up (adjusted HR, 0.52 and 0.52; 95% CI, 0.35-0.78 and 0.35-0.77; p < 0.01 and p < 0.01, respectively). The mortality rate was higher in the craniotomy group at 6 to 12 months of follow-up (adjusted HR, 2.18; 95% CI, 1.06-4.49; p < 0.05) compared to that in the control group. Thus, a timely surgical intervention for hematoma evacuation is advantageous in preventing secondary vascular events and improving outcomes in the long term. However, greater attention to secondary ischemic stroke following the initial sICH episode is needed.

- Abstract
Objective: Although no benefits of extracranial-intracranial (EC-IC) bypass surgery in preventing secondary stroke have been identified previously, the outcomes of initial symptomatic ischemic stroke and stenosis and/or occlusion among the Asian population in patients with or without bypass intervention have yet to be discussed. The authors aimed to evaluate the subsequent risk of secondary vascular disease and cardiac events in patients with and without a history of this intervention., Methods: This retrospective nationwide population-based Taiwanese registry study included 205,991 patients with initial symptomatic ischemic stroke and stenosis and/or occlusion, with imaging data obtained between 2001 and 2010. Patients who underwent EC-IC bypass (bypass group) were compared with those who had not undergone EC-IC bypass, carotid artery stenting, or carotid artery endarterectomy (nonbypass group). Patients with any previous diagnosis of ischemic or hemorrhagic stroke, moyamoya disease, cancer, or trauma were all excluded., Results: The risk of subsequent ischemic stroke events decreased by 41% in the bypass group (adjusted hazard ratio [HR] 0.59, 95% CI 0.46-0.76, p < 0.001) compared with the nonbypass group. The risk of subsequent hemorrhagic stroke events increased in the bypass group (adjusted HR 2.47, 95% CI 1.67-3.64, p < 0.001) compared with the nonbypass group., Conclusions: Bypass surgery does play an important role in revascularization of the ischemic brain, while also increasing the risk of hemorrhage in the early postoperative period. This study highlights the fact that the high risk of bypass surgery obscures the true benefit of revascularization of the ischemic brain and also emphasizes the importance of developing improved surgical technique to treat these high-risk patients.

- Abstract
This study aims to investigate the effects of treatments on the quality of life for patients with esophageal squamous cell carcinoma patients diagnosed at early and late stages. From a medical center in central Taiwan, patients who had been diagnosed with esophageal squamous cell carcinoma from February 2007 and March 2011 were recruited. Using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) and the Quality of Life Questionnaire Oesophageal 18 (QLQ-OES18), quality of life scores for 105 esophageal squamous cell carcinoma patients were obtained and assessed. Multivariate analysis was performed on the quality of life scores after stratification by cancer stage. Among early-stage esophageal squamous cell carcinoma patients, those received only surgery (S-only) performed better in physical and social functioning compared with patients who underwent surgery and concurrent chemoradiotherapy (S+CCRT) (β = 9.0, P = 0.03; β = 12.1, P = 0.04, respectively). For those that received only concurrent chemoradiotherapy (CCRT-only), they performed worse in role and emotional functioning relative to S+CCRT patients (β = -17.2, P = 0.02; β = -15.7, P = 0.05, respectively). Among late-stage patients, CCRT-only treatment gave insignificantly better global health status and functional scale scores and less severe symptoms compared to the S+CCRT option. Better functional scores and less aggravated symptoms are observed in early-stage esophageal squamous cell carcinoma patients who received surgery-only treatment relative to those that underwent both surgery and chemoradiotherapy. For late-stage esophageal cancer patients, the measured difference of quality of life is not significant between CCRT-only and S+CCRT treatments., (© The Authors 2017.

- Abstract
Loss of regenerative capacity plays a critical role in age-related autoimmune hepatitis. Evidence implicates SIRT1 and p66
shc in cell senescence, apoptosis, oxidative stress, and proliferation. This study investigated the effect of resveratrol on concanavalin A (Con A)-induced hepatitis in aged mice and the roles of SIRT1 and p66shc . Aged mice were administrated resveratrol (30 mg/kg orally) seven times at an interval of 12 h before a single intravenous injection of Con A (20 mg/kg). Results showed that the cytokines, TNF-α, IL-6, IFN-γ, and MCP-1, as well as infiltration of macrophages, neutrophils, and T lymphocytes in liver were dramatically enhanced in the mice given only Con A. The aged mouse livers showed markedly raised oxidative stress and cell apoptosis. This oxidative stress further aggravated regenerative dysfunction as indicated by the decreased levels of Ki67, PCNA, Cyclin D1, and Cdk2. Conversely, these phenomena were attenuated by pretreatment with resveratrol. Moreover, resveratrol suppressed the elevation of p66shc in the liver by reversing Con-A-mediated downregulation of SIRT1. The findings suggest that resveratrol protected against Con A-induced hepatitis in aged mice by attenuating an aberration of immune response and liver regeneration, partially via the mechanism of SIRT1-mediated repression of p66shc expression.- Published

- Abstract
Rationale: Patients with non-small cell lung cancer (NSCLC) with mutated epidermal growth factor receptor (EGFR) are relatively sensitive to EGFR-tyrosine kinase inhibitor (TKI) treatment and have longer progression-free survival (PFS) when treated with EGFR-TKI compared with platinum-based chemotherapy. However, many patients with advanced NSCLC who have mutated EGFR do not respond to first-line EGFR-TKI treatment and still have shorter PFS., Objectives: The aim of this study was to identify genetic variants associated with PFS among patients with lung adenocarcinoma who were treated with first-line EGFR-TKIs., Methods: A genome-wide association study on PFS was performed in never-smoking women diagnosed with lung adenocarcinoma and who were treated with first-line EGFR-TKIs (n = 128). Significant single-nucleotide polymorphisms (SNPs) were selected for follow-up association analysis (n = 198) and for replication assay in another independent cohort (n = 153)., Measurements and Main Results: We identified SNPs at 4q12 associated with PFS at genome-wide significance (P < 10
-8 ) and with an estimated hazard ratio of more than 4. This association was also replicated in a larger but similar cohort and in an independent NSCLC cohort. Follow-up functional analyses showed that these SNPs were associated with the expression of EGFR, which encodes the TKI target, and with a nearby gene neuromedin-U, which encodes a G protein-coupled receptor ligand known to be involved in the progression of NSCLC. Considering these as possible prognostic biomarkers for the treatment of patients with late-stage lung cancer, we found that these SNPs were not associated with EGFR mutation status or with polymorphism of the Bcl2-interacting mediator of cell death gene., Conclusions: Genetic variants in 4q12 merit further investigation to assess their potential as pharmacogenomic predictors for and to understand the biology underlying its influence on PFS in patients treated with TKI therapy.- Published

- Abstract
Objective: To examine whether the prevalence of low back pain (LBP) increased in hospital nurses with high patient care workload., Materials and Methods: A structured, self-administered questionnaire was used to collect information on the prevalence of LBP and its associated factors from 788 registered nurses from a medical center in Taiwan., Results: Among all nurses with eligible questionnaires, 567 (72.0%) had LBP. Mean daily hours of working, standing, and walking were persistently longer in the LBP group. Results from multivariate logistic regression analysis showed that daily working for 1 hour longer is linked to a 35% (95% confidence interval (CI)=2-78%) greater risk of LBP. Compared with <2 years of service as nurse, nurses with 2-5 years of service had the highest risk (odds ratio (OR)=2.11, 95% CI=1.07-4.18). LBP risk was also higher for nurses with chore duty responsibilities (OR=1.99, 95% CI=1.12-3.53) and other back related disorders (OR=4.43, 95% CI=1.99-9.86)., Conclusion: Our results suggest that longer daily working hours and a large number of cared patients per shift should be discouraged in order to prevent musculoskeletal problems such as LBP in registered nurses., (Copyright © 2016.

- Abstract
Background: Cardiologists who frequently perform percutaneous coronary interventions (PCIs) are exposed to high levels of radiation; therefore, their risk of cancer may be higher compared with other internists or cardiologists who perform fewer PCIs., Methods: Data were obtained from the Taiwan National Health Insurance Research Database for the 2000-2011 period. A cohort of 542 cardiologists was randomly frequency-matched according to age and sex with four other internists to form a cohort of noncardiologist controls. The incidence of cancer was measured for both cohorts, who were followed up until the end of 2011. Cox proportional hazards models were employed to analyse the risk of cancer between cardiologist and control cohorts., Results: In general, the cardiologists did not have a higher risk of cancer compared with the other internists. However, the cardiologists who worked in medical centres or regional hospitals had a higher risk of cancer than did the other internists in the same work settings. Furthermore, the cardiologists working in medical centres or regional hospitals (large hospitals) who performed >15 PCIs per year had a higher risk of cancer than did those working in district hospitals (small hospitals) or clinics who performed ≤15 PCIs per year., Conclusion: Cardiologists who frequently perform PCIs have a higher risk of cancer compared with other internists or cardiologists who perform relatively fewer PCIs. Protection from radiation exposure should therefore be emphasized in coronary catheterization laboratories., (© 2016 Stichting European Society for Clinical Investigation Journal Foundation.)

- Abstract
Using a retrospective cohort study design, we report empirical evidence on the effect of parental socioeconomic status, primary care, and health care expenditure associated with preterm or low-birth-weight (PLBW) babies on their mortality (neonatal, postneonatal, and under-5 mortality) under a universal health care system. A total of 4668 singleton PLBW babies born in Taiwan between January 1 and December 31, 2001, are extracted from a population-based medical claims database for a follow-up of up to 5 years. Multivariate survival models suggest the positive effect of higher parental income is significant in neonatal period but diminishes in later stages. Consistent inverse relationship is observed between adequate antenatal care and the three outcomes: neonatal hazard ratio (HR) = 0.494, 95% confidence interval (CI) = 0.312 to 0.783; postneonatal HR = 0.282, 95% CI = 0.102 to 0.774; and under-5 HR = 0.575, 95% CI = 0.386 to 0.857. Primary care services uptake should be actively promoted, particularly in lower income groups, to prevent premature PLBW mortality., (© 2015 APJPH.)

- Abstract
Background: Video-assisted thoracoscopic surgery (VATS) is a minimally invasive alternative to conventional surgery (CS). We aimed to estimate the short-term cost-effectiveness of VATS vs. CS for clinical stage I non-small cell lung cancer (NSCLC-c-stage-I) patients from the payer's perspective (National Health Insurance)., Methods: We identified NSCLC-c-stage-I patients diagnosed and received surgery within 2007-2009 through a comprehensive population-based database containing cancer and death registries, and reimbursement data. The duration of interest was 1 year. We included potential confounding covariables through literature searching and our own experience, and used a propensity score to construct a 1:1 population for adjustment., Results: Our study population constituted 966 patients. The mean hospital stay [days, standard deviation (SD)] were 14.4 [7] and 16.1 (7.7) for VATS and CS respectively (P=0.002). The mean cost (2013 USD) and survival (year) was $22,316 vs. $21,976 and 0.98 vs. 0.974 for VATS vs. CS. The probability for VATS to be cost-effective (i.e., positive net benefit) was 0.49 & 0.56 at willingness-to-pay (WTP) 50,000 & 100,000 USD/life-year, respectively., Conclusions: We provide the first empirical evidence that when compared to CS, VATS was potentially cost-effective in the short term (1 year) within the common WTP levels in Taiwan.

- Abstract
Abstract Background: Learning style is a major consideration in planning for effective and efficient instruction and learning. Learning style has been shown to influence academic performance in the previous research. Little is known about Taiwanese students' learning styles, particularly in the field of nursing education. Aim: This purpose of this study was to identify the relationship between learning styles and academic performance among nursing students in a five-year associate degree of nursing (ADN) program and a two-year bachelor of science in nursing (BSN) program in Taiwan. Methods/Design: This study employed a descriptive and exploratory design. The Chinese version of the Myers-Briggs Type Indicator (MBTI) Form M was an instrument. Data such as grade point average (GPA) were obtained from the Office of Academic Affairs and the Registrar computerized records. Descriptive statistics, one-way analysis of variance ANOVA) and chi-square statistical analysis were used to explore the relationship between academic performance and learning style in Taiwanese nursing students. Results/Findings: The study sample included 285 nursing students: 96 students in a two-year BSN program, and 189 students in a five-year ADN program. Two common learning styles were found: introversion, sensing, thinking, and judging (ISTJ); and introversion, sensing, feeling, and judging (ISFJ). A sensing-judging pair was identified in 43.3% of the participants. Academic performance was significantly related to learning style (p < 0.05, d.f. = 15). Conclusion: The results of this study can help educators devise classroom and clinical instructional strategies that respond to individual needs in order to maximize academic performance and enhance student success. A large sample is recommended for further research. Understanding the learning style preferences of students can enhance learning for those who are under performing in their academic studies, thereby enhancing nursing education.

- Abstract
Background/purpose: Delay in diagnosis may affect the survival of breast cancer patients. The purpose of this study was to investigate delayed diagnosis for breast cancer patients in Taiwan., Methods: This study was conducted via one-to-one interviews with structured questionnaires in hospital outpatient visit. Included were 600 breast cancer patients seeking medical care in two medical centers in central Taiwan., Results: Average delay in breast cancer diagnosis was 27.8 days. Service level of the patients' first visit and number of hospitals patients visited before obtaining a correct diagnosis were significantly associated with delay in diagnosis. Logistic regression analysis found that patients who had visited two, and three or more hospitals before getting a correct diagnosis had longer delays in diagnosis than patients who had visited one hospital (odds ratio = 2.23 and 9.26, 95% confidence interval 1.37-3.63 and 95% CI:3.87-22.15, respectively)., Conclusion: Results of this study are anticipated to serve as a reference for the government and medical institutions to develop policies to reduce the number of hospitals visited before diagnosis for breast cancer patients, and ultimately to achieve the goal of early detection and treatment., (Copyright © 2013.

- Abstract
Background: Colorectal cancer is the third most commonly diagnosed cancer worldwide. Few studies have addressed the causes and risks of treatment refusal in a universal health insurance setting., Methods: We examined the characteristics and survival associated with treatment refusal in patients with newly diagnosed colorectal cancer in Taiwan during 2004-2008. Treatment refusal was defined as not undergoing any cancer treatment within 4 months of confirmed cancer diagnosis. Patient data were extracted from four national databases. Factors associated with treatment refusal were identified through logistic regression using the generalized estimating equation method, and survival analysis was performed using the Cox proportional hazards model., Results: Of the 41,340 new colorectal cancer cases diagnosed, 3,612 patients (8.74%) refused treatment. Treatment refusal rate was higher in patients with less urbanized areas of residence, lower incomes, preexisting catastrophic illnesses, cancer stages of 0 and IV, and diagnoses at regional and district hospitals. Logistic regression analysis revealed that patients aged >75 years were the most likely to refuse treatment (OR, 1.87); patients with catastrophic illnesses (OR, 1.66) and stage IV cancer (OR, 1.43) had significantly higher refusal rates. The treatment refusers had 2.66 times the risk of death of those who received treatment. Factors associated with an increased risk of death in refusers included age ≥ 75 years, insured monthly salary ≥ 22,801 NTD, low-income household or aboriginal status, and advanced cancer stage (especially stage IV; HR, 11.33)., Conclusion: Our results show a lower 5-year survival for colorectal patients who refused treatment than for those who underwent treatment within 4 months. An age of 75 years or older, low-income household status, advanced stages of cancer, especially stage IV, were associated with higher risks of death for those who refused treatment.

- Abstract
Purpose: The responses of polyps to light essentially determine the diagnostic capability of an endoscopy system in differentiating adenomas from hyperplastic polyps. Compared with white light colonoscopy (WLC), narrow-band imaging (NBI) is expected to improve the diagnostic capability. The diagnostic capabilities of WLC and NBI are evaluated and compared based on the polyp responses., Methods: The following WLC and NBI images were retrospectively reviewed and categorized: 195 images and polyps (89 WLC, 106 NBI) with the best visual quality were categorized in the best image group (BG), and 484 images of 242 polyps (both WLC and NBI) were categorized in the paired image group (PG). For each reflection of light used for WLC or NBI, the polyp responses were objectively expressed as reflection features. The reflection features were then used to establish a classification model for identifying adenomas. The diagnostic capability of reflection feature or classification model was measured by the area under the receiver operating characteristic curve (AUC)., Results: In both image groups, the diverse and heterogeneous features of the polyp responses enabled accurate identification of adenomas, regardless of the light source used for WLC and NBI. For differential diagnosis of adenomas and hyperplastic polyps, the WLC and NBI did not significantly differ in BG (AUC, 0.905 and 0.922, respectively; P = 0.690) or in PG (AUC, 0.782 and 0. 769, respectively; P = 0.755)., Conclusions: Using WLC and NBI as classification models is effective in differential diagnosis of colorectal polyps and exhibited similar capabilities.

- Abstract
Rationale and Objectives: Using low-dose computed tomography (LDCT), small and heterogeneous lung tumors are detected in screening. The criteria for assessing detected tumors are crucial for determining follow-up or resection strategies. The purpose of this study was to investigate the capacity of density features in differentiating lung tumors., Materials and Methods: From July 2008 to December 2011, 48 surgically confirmed tumors (29 malignancies, comprising 17 cases of adenocarcinoma and 12 cases of adenocarcinoma in situ [AdIs], and 19 benignancies, comprising 11 cases of atypical adenomatous hyperplasia [AAH] and eight cases of benign non-AAH) in 38 patients were retrospectively evaluated, indicating that the positive predictive value (PPV) of physicians is 60.4% (29/48). Three types of density features, tumor disappearance rate (TDR), mean, and entropy, were obtained from the CT values of detected tumors., Results: Entropy is capable of differentiating malignancy from benignancy but is limited in differentiating AdIs from benign non-AAH. The combination of entropy and TDR is effective for predicting malignancy with an accuracy of 87.5% (42/48) and a PPV of 89.7% (26/29), improving the PPV of physicians by 29.3%. The combination of entropy and mean adequately clarifies the four pathology groups with an accuracy of 72.9% (35/48). For tumors with a mean below -400 Hounsfield units, the criterion of an entropy larger than 5.4 might be appropriate for diagnosing malignancy. For others, the pathology is either benign non-AAH or adenocarcinoma; adenocarcinoma has a higher entropy than benign non-AAH, with the exception of tuberculoma., Conclusions: Combining density features enables differentiating heterogeneous lung tumors in LDCT., (Copyright © 2014 AUR.

- Abstract
Background: Subcellular localization of apurinic/apyrimidinic endonuclease-1/redox factor-1 (Ape1) has been demonstrated to promote lung tumor malignancy via NF-κB activation. We hypothesized that increased cytoplasmic Ape1 expression might cause NF-κB activation by p53 aberration, and result in poor outcome in non-small cell lung cancer (NSCLC)., Methods: Herein, knockdown of E6 or p53 and overexpression of E6 were performed in various lung cancer cells to test whether cytoplasmic Ape1 expression could be elevated by p53 aberration. To examine whether cytoplasmic Ape1 could be associated with patients' outcome, 125 lung tumors from patients with NSCLC were collected to determine Ape1 protein and mRNA expression by immunohistochemistry and real-time RT-PCR., Results: Our data showed that cytoplasmic Ape1 decreased in E6-knockdown TL-1 cells and increased in E6-overexpressed TL-4 and p53-knockdown H520 cells; and cell invasion capability was dependent on the presence of cytoplasmic Ape1. Increases in cytoplasmic Ape1 by p53 aberration may be through activation of Ape1 transcription and S-nitrosation of Ape1 protein. Kaplan-Meier and Cox models showed that patients with high cytoplasmic Ape1 had shorter cancer-specific survival (CSS) and relapse-free survival (RFS) periods than did those with low cytoplasmic Ape1., Conclusions: We suggest that cytoplasmic Ape1 expression elevated by p53 aberration may be used to predict poor survival and relapse in patients with NSCLC.

- Abstract
Background: ATPase-family, AAA domain containing 3A (ATAD3A) is located on human chromosome 1p36.33, and high endogenous expression may associate with radio- and chemosensitivity. This study was conducted to investigate the significance of ATAD3A in glioblastoma multiforme (GBM)., Methods: Clinical significance of ATAD3A expression was assessed by immunohistochemistry in 67 GBM specimens, and prognostic value was assessed in 32 GBM patients statistically. To investigate in vitro phenotypic effects of ATAD3A, cell viability was measured using a clonogenic survival assay under either knockdown or ectopic expression of ATAD3A in GBM cell lines. The effects of ATAD3A knockdown on targeted DNA repair-associated proteins in T98G cells were evaluated using immunofluorescence and Western blotting., Results: Clinically, high expression of ATAD3A was independent of O(6)-DNA methylguanine-methyltransferase methylation status and correlated with worse prognosis. In vitro, high ATAD3A-expressing T98G cells were more resistant to radiation-induced cell death compared with control and low endogenous ATAD3A U87MG cells. After silencing ATAD3A, T98G cells became more sensitive to radiation. On the other hand, enforced ATAD3A expression in U87MG cells exhibited increased radioresistance. ATAD3A may coordinate with aldo-keto reductase genes and participate in bioactivation or detoxication of temozolomide. Surprisingly, deficient DNA repair after irradiation was observed in T98G/ATAD3A knockdown as a result of decreased nuclear ataxia telangiectasia mutated kinase and histones H2AX and H3, which was also evidenced by the sustained elevation of poly (ADP-ribose) polymerase prior to and after radiation treatment., Conclusion: Our data suggest that high expression of ATAD3A is an independent biomarker for radioresistance in GBM. ATAD3A could be a potential target for therapy.

- Abstract
Dihydrodiol dehydrogenase (DDH) is frequently detected in cancer cells, and its overexpression correlates with drug resistance, the downregulation of DNA repair mechanisms, increased frequency of tumor recurrence, cancer cell metastasis and poor prognosis. The silencing of DDH expression using siRNA, on the other hand, reduces drug resistance and cancer cell mobility. These data suggest that DDH may be an oncogene-related protein. However, no specific DDH inhibitor has been identified to date. Thus, in this study, we used DDH as a target enzyme in a live-cell enzyme-linked immunosorbent assay to screen Chinese medicinal herb extracts (CMHEs) with the aim of identifying a DDH inhibitor. Using this method, we found 49 among 796 CMHEs that inhibited DDH expression. We selected three potential extracts, which had the highest activity against DDH, for further fractionation using high-performance liquid chromatography. The active ingredient was identified by immunoblot analysis. The function of the active ingredient was characterized by cell function analysis. Our results revealed that the CMHE-purified compounds targeted DDH, inducing autophagy and reducing DNA repair, which in turn enhanced the cytotoxic effects of the anticancer drugs and irradiation.

- Abstract
Background: Polymorphisms (1082A>G, - 819C>T, and -592G>A) in the interleukin-10 (IL10) promoter are associated with its transcriptional activity. IL10 induction by cigarette smoking plays a role in smoking-related lung tumor progression. We therefore expected to find a difference in impact of IL10 haplotypes on overall survival (OS) and relapse-free survival (RFS) between squamous cell carcinomas (SCC) and adenocarcinomas (ADC) of lung., Materials and Methods: Normal lung tissues adjacent to resected tumors from 439 lung cancer patients were collected to determine IL10 haplotypes (ATA and non-ATA) by direct sequencing and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Kaplan-Meier and multivariate Cox regression models were used to assess the impact of IL10 haplotype on OS and RFS. Resluts: The non-ATA haplotype was more prevalent in patients with nodal metastatic tumors (N1 and N2) than in those with non-nodal metastatic tumors (N0). This observation was only made for patients with SCC and not ADC. Patients with SCC with the non-ATA haplotype had poorer OS and RFS when compared to those with the ATA haplotype, whereas IL10 haplotype was not associated with the clinical outcome of patients with ADC., Conclusion: The IL10 haplotype may independently predict survival and relapse in patients with surgically resected SCC, but not ADC.

- Abstract
Objectives: Video-assisted thoracoscopic surgery (VATS) is possibly associated with reduced acute pain and narcotics consumption when compared to open surgery, but little is known about the long-term effect. The goal of our study was to evaluate whether narcotics consumption is consistently lower after VATS for early stage non-small cell lung cancer (NSCLC), as compared to open surgery, during one-year follow-up., Methods: This nationwide retrospective cohort study was conducted using data relating to cancer registry and national compulsory comprehensive claims in Taiwan. Our study cases were those newly diagnosed with clinical Stage I NSCLC, who underwent primary lung resection in the year 2007. The date of the admission during which index surgery was performed was used as the index date. We compared the use of narcotics, between the VATS and open surgery groups, over a period of one year following the index date. We defined narcotics as either Level 1 or 2 drugs as regulated in Taiwan. We also used an equiananalgesic dose chart to convert drug consumption into a uniform narcotics equivalent dose. Chi-square and t-tests were used for statistical analysis., Results: We identified 329 cases (114 for VATS and 215 for open surgery). These two groups were balanced for most clinical variables. VATS was associated with lower narcotics consumption during the index admission (mean equivalent dose of intravenous morphine: 54.6 vs 71.4 mg) and this trend extended to the period covering the 2nd to 12th month after index date (73.8 vs 149.5mg)., Conclusions: Narcotics consumption is consistently lower after VATS for early stage NSCLC, as compared to open surgery. Further prospective studies would be of great value in validating this finding.

- Abstract
Manganese superoxide dismutase (MnSOD) is an antioxidant enzyme responsible for the elimination of superoxide radical. The role of MnSOD in tumor progression in different human cancers is still controversial. In the present study, MnSOD expression in lung cancer cells was explored by knockdown or overexpression using transfection of a short hairpin RNA (shRNA) or an expression vector, respectively, to determine whether MnSOD expression mediates lung cancer cell migration, invasion, and oncogenic potential by increasing FoxM1 and MMP2 expression. Western blotting showed that FoxM1 and MMP2 expression was dependent on MnSOD expression, suggesting that FoxM1 could be upregulated by MnSOD. Three FoxM1 promoters were constructed to verify this activation of FoxM1 by MnSOD and to determine the transcription factors responsible. Luciferase reporter and chromatin immunoprecipitation assays indicated that MnSOD overexpression in lung cancer cells promoted binding of E2F1 and Sp1 to their putative FoxM1 promoter-binding sites and activated FoxM1 reporter activity. MnSOD also enhanced the potential for cell migration, invasion, and anchorage-independent colony growth on soft-agar plates, again via upregulation of FoxM1 and MMP2 expression. In patients with lung cancer, evaluation of MnSOD expression in lung tumors by immunohistochemistry indicated a positive correlation between FoxM1 and MMP2 mRNA expressions. Kaplan-Meier and Cox regression analysis revealed a poorer overall survival (OS) and relapse-free survival (RFS) in patients with MnSOD-positive tumors than with MnSOD-negative tumors. We conclude that MnSOD may promote tumor aggressiveness via upregulation of the FoxM1-MMP2 axis, and that MnSOD expression can independently predict survival and relapse in patients with resected lung adenocarcinoma.

- Abstract
Objective: Lung cancer is not only one of the most prevalent cancers but is also a lethal disease with a very low 5-year survival rate. Delay in diagnosis further reduces the chance of early treatment and worsens patients' survival. The purpose of this study was to understand the delay in the diagnosis of lung cancer under the healthcare system in Taiwan, and to identify the factors associated with it., Methods: A total of 840 patients diagnosed with lung cancer who had completed or were undergoing cancer treatments were recruited from a medical center in central Taiwan from July 2007 to January 2011. Structured questionnaires were administered regarding demographic characteristics, factors associated with their time to diagnosis and the length of delay in days., Results: Mean age was 62.68 years with 52.16 days to diagnosis on average. Number of hospital visits before confirmation of diagnosis differed significantly with the level of healthcare institution initially visited (P < 0.001). Compared with patients who had three or more hospital visits, patients who only visited two and one hospital(s) had a significant 34.91-day (95% confidence interval: 16.29-53.53) and 42.25-day (95% confidence interval: 20.76-63.76) reduction in their time to diagnosis (P < 0.001)., Conclusions: As the number of hospital visits increased, the delay in diagnosis also increased. It is vital to shorten the time to diagnosis for lung cancer patients by limiting the number of medical visits and educating the public to restrict excessive use of medical resources and strengthen their trust in medical professionals.

- Abstract
Aim: The purpose of this study is to investigate the impact of breast cancer awareness on the attendance for screening among women with breast cancer prior to diagnoses of breast cancer., Background: Breast cancer is the most commonly diagnosed cancer for women in Taiwan and its incidence rate continues to increase. However, screening for breast cancer is still not common even if the incidence rate has topped the list from 2003 to 2010., Methods: A cross-sectional study was conducted among women diagnosed with breast cancer. Subjects (535 women) were recruited from two medical centres in central Taiwan. Information on attendance for breast cancer screening was collected by self-report. Chi-square test and logistic regression were utilized to analyse the relationships between awareness of breast cancer and attendance at screening., Findings: The results indicated that pre-diagnostic awareness of 'the concept of early treatment relating to higher cure rate'[odds ratio (OR): 4.09; 95% confidence interval (CI): 1.12-14.9], 'various breast cancer screening methods' (OR:3.00; 95% CI: 1.23-7.30), 'the coverage of breast cancer screening programme in the National Health Insurance' (OR:1.76; 95% CI: 1.03-3.02) and 'breast self-examination after each menstrual cycle' (OR:3.42; 95% CI: 1.99-5.87) were all significantly associated with the screening procedures performed., Conclusions: Findings of this study indicated that particular attention should be paid towards enhancement of women's knowledge for prevention and early detection of breast cancer through educational efforts by nurse professionals, medical institutions and/or civil organizations., (© 2012 The Authors.

- Abstract
IL-10 is associated with tumor malignancy via immune escape. We hypothesized that IL-10 haplotypes categorized by IL-10 promoter polymorphisms at -1082A>G, -819C>T, and -592C>A might influence IL-10 expression and give rise to non-small cell lung cancer (NSCLC) patients with poor outcomes and relapse. We collected adjacent normal tissues from 385 NSCLC patients to determine IL-10 haplotypes by direct sequencing and polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP). Of the 385 tumors, 241 were available to evaluate IL-10 mRNA expression levels by real-time RT-PCR. The influence of IL-10 haplotypes on overall survival (OS) and relapse free survival (RFS) were determined by Kaplan-Meier and multivariate Cox regression analysis. The results showed that IL-10 mRNA levels were significantly higher in tumors with the non-ATA haplotype than with the ATA haplotype (P = 0.004). Patients with the non-ATA haplotype had shorter OS and RFS periods than did patients with the ATA haplotype. This may be associated with the observation that the number of tumor-infiltrating lymphocytes was decreased in the tumors with higher levels of IL-10. Consistently, T cells from the peripheral blood of the patients with non-ATA haplotype were more susceptible to apoptosis and less cytotoxic to tumor cells, compared to those from the patients with ATA haplotype. The results suggest that IL-10 can promote tumor malignancy via promoting T cell apoptosis and tumor cell survival, and IL-10 haplotype evaluated by PCR-RFLP or direct sequencing may be used to predict survival and relapse in resected NSCLC, helping clinicians to make appropriate decisions on treatment of the patients.

- Abstract
Background: It is well known that patients' health risk behavior will affect the survival outcome of diseases. Smoking alone is a significant health risk behavior that affects the survival outcome of lung cancers; other health risk behaviors remained unknown. Therefore, this study discusses the effects of health risk behaviors on the survival outcome in lung cancer patients., Methods: The study sample consists of 1410 newly diagnosed, histologically confirmed lung cancer patients from a medical center hospital in central Taiwan. The patient medical records were collected from 1 January 1998 to May 2004. Besides descriptive statistical analyses, t-test and analysis of variance were used to analyze the relationship between patient characteristics, patient health risk behavior and survival. Chi-square tests were used to analyze the relationship between patient characteristics, patient health risk behavior and stage of disease. Cox's proportional hazards regression was computed for the risk of survival by patient characteristics and patient health risk behavior., Results: The results showed that there is a significant difference between smoking (P < 0.001), alcohol consumption (P = 0.027), routine physical check-ups (out-of-pocket) (P < 0.001) and survival time. Patients with betel-nut consumption did not have a significant effect upon survival than non-betel-nut consumption patients. When holding constants all the variables in Cox's proportional hazards model, smoking (P = 0.02), routine physical check-ups (out-of-pocket) (P = 0.017) and stage at diagnosis of lung cancer (P < 0.001) will affect lung cancer patients' survival., Conclusions: This study presented evidence showing that smoking, alcohol consumption behavior, routine physical check-ups and stage at diagnosis play an important role in determining the survival of lung cancer patients.

- Abstract
Water demands in arid and semi-arid areas, coupled with increased human populations and concomitant changes in land use, can greatly alter aquatic ecosystems. A good example of this type of system occurs along the eastern slope of the Colorado Rocky Mountains, U.S.A. Long-term macroinvertebrate metric data from the Big Thompson and Cache la Poudre Rivers, Colorado, were collected at one site above, and three sites in and downstream from urban areas. These data were compared both with regional reference and single reference sites in the respective rivers. Using the surrogate variables of potential urban impact (population and housing units), and the environmental gradient represented primarily by chemical factors, it was determined that there was an effect of urban land use that was reflected in the macroinvertebrate assemblages in both rivers. The most robust results were usually seen when regional reference data were used. However, even using only the upstream reference site in either river indicated some negative impacts from the urban areas. The long-term data, particularly in the Cache la Poudre River, showed that water quality has not been getting worse and there is some evidence of a slight improvement in downstream reaches, even with increased urban development.

- Abstract
A randomised trial was undertaken to compare the effect of three oral care protocols in delaying the onset of stomatitis and reducing oral injury in nasopharyngeal cancer patients undergoing radiotherapy, 30 eligible patients with a mean age of 56.2 years were recruited and evenly allocated to one of the three groups using a randomly permuted blocks method. Patients allocated to group E1 and group E2 were given the same instructions on oral care at 1 day, and 1 week before radiotherapy, respectively, while those allocated to the control group were given no instructions. We use the Oral Assessment Guide to assess the oral physical conditions of these patients daily. Our findings revealed that the patients in the E2 group not only had later onset of stomatitis than those in the control and the E1 groups, but also had lesser degree of oral injury measured by the overall assessment score. We thereby recommend the use of the E2 protocol for delaying the onset of stomatitis and reducing oral injury in nasopharyngeal cancer patients undergoing radiotherapy.

- Abstract
We report on two siblings who developed severe neonatal alloimmune thrombocytopenia (NAIT) due to an alloantibody against a labile component or components of the HPA-3a (Baka) antigen. The antibody reacted only with fresh, unfixed platelets by the solid-phase red cell adherence test, immunofluorescence test and mixed passive haemagglutination test. In the latter method, weakly fixed platelets also gave a weak positive reaction. Monoclonal-antibody-specific immobilization of platelet antigens and immunoblotting tests gave negative results. Our findings may possibly help to explain why in some cases of NAIT no platelet-specific antibody is demonstrable in tests with fixed or solubilized platelets.

- Abstract
Neonatal jaundice is known to be more severe in Taiwanese infants than in Caucasian infants. Although ABO fetomaternal incompatibility and glucose-6-phosphate dehydrogenase deficiency have been shown to play a role in the etiology of neonatal jaundice in some Taiwanese infants, the etiology in the majority of cases is unknown. In this study we found that in Taiwanese newborn infants, the red cell Le(a) antigen appeared later in infants who were jaundiced (peak serum bilirubin levels of > 12 mg/dl during the first week of life) than in infants who were not. However, the Leb antigen, and hence the transferase encoded by the Se and Se(w) genes, did not appear to be similarly involved in the etiology of physiological jaundice. Thus it would appear that the Le gene-specified transferase is less active or has a delayed function, in jaundiced infants. The relationship between the Le gene-specified transferase and bilirubin has yet to be established.

- Abstract
Lewis phenotyping of 487 blood samples from Chinese newborn infants and young children, revealed that 50% of cord cells were Le(a-b+) and 50% Le(a-b-). The weak Leb antigen of Le(a-b+) cord cells is most likely produced by the newborn infant rather than of maternal origin and it appears that these infants eventually develop by way of an intermediate Le(a+b+) stage into the adult Le(a-b+) phenotype. Most infants with Le(a-b-) cord cells, but not all, appear to develop through a transitional Le(a+b-) stage, into Le (a+b+) by about 1 month of age, most likely continuing as such into adulthood. This development of Le(a-b-) cord cells into the adult Le(a+b+) phenotype is postulated to be the result of the weak secretor gene Se omega. Those infants with Le(a-b-) cord cells that do not convert to Le(a+b+) during the first month of life, most likely remain as such into adulthood. The blood of 120 adult voluntary blood donors, used as controls, reconfirmed adult Chinese phenotypic frequencies of approximately 70% Le(a-b+), 22% Le(a+b+) and 8% Le(a-b-).

- Abstract
In order to establish Taiwan monkey lymphoblastoid cell lines, attempts were made to raise the susceptibility of monkey lymphocytes to Epstein-Barr virus (EBV) by chemical and enzymatic treatments. EBV infectivity to monkey T and B cells were tested by detection of EBV early antigens in infected cells with the indirect immunofluorescent antibody technique. Treatments of monkey unfractionated lymphocytes with DEAE-Dextran (160 microgram/ml) for 1 hr, ethylenediamine tetra-acetic acid (EDTA, 0.5%) for 10 min, 5-bromodeoxyuridine (BUdR, 12.5 microgram/ml) for 23 hr and 5-iodo-2'-deoxyuridine (IUdR, 12.5 microgram/ml) for 20 hr raised the susceptibility of the cells to EBV. However, trypsin treatment (0.05, 0.1 and 0.2%) at 37 degrees C for 5 min did not affect cell susceptibility to EBV. Unfractionated lymphocytes, T cells which were purified by rosette formation with sheep red blood cells, and a B cell-rich population obtained by the treatment of lymphocytes with antithymoycte serum were treated with the chemicals described above. The results showed that although the possibility of T cell susceptibility to EBV could not be ruled out because of 1 to 2.5% of B cell contamination in purified T cells, the main target cells in Taiwan monkey leukocytes for EBV infection were B cells.
