The prevalence of depression in patients with cancer is high, especially for patients with advanced cancer. In this study, we evaluated the prevalence of depression in prostate cancer patients in Taiwan and the association between depression and mortality in prostate cancer. This study included 1101 newly diagnosed patients with prostate cancer. We tracked the medical information of these patients from diagnosis until the end of 2012. Patients were divided into two groups according to presence or absence of depression diagnosis, and were further divided into three stages by initial treatments: localized or locally advanced, metastatic, and castration-resistant prostate cancer. Of 1101 participants, 267 (24.3%) had depression. By the end of the follow-up period (M = 8.30 ± 3.12 years), 77 (28.8%) patients in the depression group and 194 (23.3%) in the non-depressed group died. Depression was associated with higher mortality risk, (aHR 1.37; 95% CI [ 1.04–1.80]; p value 0.01). Patients in the metastatic prostate cancer group with depression had a significantly higher mortality risk compared to the non-depressed group, (aHR, 1.49; 95% CI [1.05–2.11]; p value 0.02). The impact of depression on mortality risk was not significant in either the localized or locally advanced or the castration-resistant prostate cancer groups. Our study showed that depression is related to an increased mortality risk for patients with prostate cancer, especially for metastatic prostate cancer. These results indicate that urologists should pay attention to the mood and psychiatric disorders of patients with prostate cancer.

Background: Pneumothorax is a rare complication of acupuncture and the risk factors are unclear. Objective: This study analysed the incidence of post-acupuncture pneumothorax requiring hospitalisation in a one-million-sample cohort derived from Taiwan’s National Health Insurance Research Database. Methods: We tracked this cohort between 1997 and 2012 and recorded all medical insurance information. Subjects were categorised according to gender, insurance amount, comorbidities, residential area, and number of acupuncture treatments. Pneumothorax risk was evaluated according to different demographic and medical variables by logistic regression analysis using an adjusted odds ratio (aOR) with a 95% confidence interval (95% CI). Results: Overall, 411 734 patients undergoing 5 407 378 acupuncture treatments were identified with data collected over the first 7 days after acupuncture. The incidence rates of iatrogenic pneumothorax were 0.87 per 1 000 000 acupuncture treatments overall and 1.75 per 1 000 000 acupuncture treatments in “at-risk” anatomical areas. Multivariate logistic regression demonstrated that a history of thoracic surgery (aOR 7.85, 95% CI 3.49 to 9.25), chronic bronchitis (aOR 2.61, 95% CI 1.03 to 6.87), emphysema (aOR 4.87, 95% CI 1.03 to 7.96), pneumonia (aOR 2.09, 95% CI 1.44 to 2.72), tuberculosis (aOR 3.65, 95% CI 1.39 to 9.56), and lung cancer (aOR 3.85, 95% CI 1.53 to 9.73) may increase the post-acupuncture risk of iatrogenic pneumothorax. Men had a higher risk of pneumothorax than women (aOR 3.41, 95% CI 1.36 to 8.57). The number of treatments was not associated with risk of pneumothorax. Conclusions: Patients with a history of lung disease including chronic bronchitis, emphysema, tuberculosis, lung cancer and pneumonia, and a history of thoracic surgery, might have an increased post-acupuncture risk of pneumothorax. This information may possibly help physicians avoid post-acupuncture pneumothorax.

Abstract— The intent of this study is to investigate some critical factors that affect legibility and visual fatigue while reading on an electronic‐paper display in terms of ergonomics. Anti‐reflection surface treatment, ambient illumination, and bending curvature are taken into account to evaluate their effects by using the method of letter‐search task. The results showed that the surface treatment with high degrees of anti‐reflection significantly improved the legibility and reduces visual fatigue. Thus, electronic‐paper manufacturers may choose a much better surface treatment in order to meet ergonomic demand. In addition, the findings in the present study also indicate that subjects reported less visual fatigue on a bending surface of a visual display unit, in comparison with a plane surface. It is proven that these ergonomic evaluations for electronic paper provide manufactures with useful information to design suitable products for users.

Background: Cellulitis is a complication of acupuncture, but the risk factors and annualized incidence remain unclear. Objective: This study analyzed the incidence and risk factors of cellulitis related to acupuncture in a cohort of one million participants derived from Taiwan’s Longitudinal Health Insurance Database. Methods: We tracked this cohort between 1997 and 2012 and recorded all outpatient medical information including diagnosis and treatment. Patients were categorized according to age, gender, comorbidities, residential area, and number of acupuncture treatments. We compared the incidence and risk of cellulitis between different demographics and comorbidities by logistic regression analysis and adjusted odds ratio (aOR) with a 95% confidence interval (95% CI). Results: We included 407,802 patients and 6,207,378 acupuncture treatments. The incidence of cellulitis after acupuncture was 64.4 per 100,000 courses of acupuncture treatment. The most common sites of cellulitis after acupuncture were the legs, feet, and face. Comorbidity was associated with post-acupuncture cellulitis; a multivariate logistic regression analysis showed that chronic kidney disease (aOR, 1.71; 95% CI, 1.55–1.88), rheumatoid arthritis (aOR, 1.86; 95% CI, 1.21–3.60), liver cirrhosis (aOR, 1.23; 95% CI, 1.15–1.32), diabetes mellitus (aOR, 1.69; 95% CI, 1.57–1.82), stroke (aOR, 1.44; 95% CI, 1.31–1.58), varicose veins (aOR, 2.38; 95% CI, 2.17–2.84), or heart failure (aOR, 1.81; 95% CI, 1.65–1.98) significantly increased cellulitis. Repeated exposure to acupuncture treatment was associated with an increased risk of cellulitis. Conclusions: A variety of chronic diseases may increase the risk of cellulitis after acupuncture. Physicians asked about past medical history before acupuncture might help to reduce cellulitis.

This is the first study to examine the use of and the prescription pattern for TCM in urolithiasis patients using a random, national population-based sample. More than 62% of urolithiasis patients use TCM, and patients with polypharmacy, multiple comorbidities, and stone in the ureter are more likely to use TCM. The most frequently prescribed Chinese medicine formulae were Jia-Wei-Xiao-Yao-San Extract Powder and Ji-Sheng-Shen-Qi-Wan Extract Powder, which were reported to retard the progression of renal failure and alleviate flank pain or tenderness.
