Anti-tuberculosis treatments and risk of hepatocellular carcinoma in tuberculosis patients with liver cirrhosis: a population-based case-control study.

The objective of this study was to evaluate the association between the use of anti-tuberculosis (anti-TB) agents, isoniazid (INH), rifampicin (RIF), and their combination (INH + RIF), and the risk of hepatocellular carcinoma (HCC) in cirrhotic patients. This population-based case-control study was conducted using a research database of Taiwan's National Health Insurance program. Cirrhotic patients first diagnosed with HCC between 1996 and 2011 (n = 50,351), among whom 4,738 were anti-TB medication users, were evaluated. Cirrhotic patients who did not develop HCC within the same period, frequency-matched according to age, sex, and index year, were evaluated as the control group (n = 47,488). The adjusted odds ratio (OR) of HCC was 1.34 [95 % confidence interval (CI), 1.20-1.50] in INH + RIF users compared with non-INH + RIF users. Long-term (>12 months) use of INH, RIF, and INH + RIF was significantly associated with increased risk of HCC, with an adjusted OR of 3.51 (95 % CI, 2.11-5.84), 4.17 (95 % CI, 2.76-4.31), and 7.17 (95 % CI, 4.08-12.6), respectively, after adjusting for age, sex, and comorbidities. An average dose of INH + RIF >16,050 mg/year was associated with increased risk of HCC in cirrhotic patients, with an adjusted OR of 1.48 (95 % CI, 1.27-1.73). Our results indicate that cirrhotic patients with long-term or high-dose INH and RIF treatment, particularly their combination, are associated with increased risk of HCC development.

Increased subsequent risk of acute coronary syndrome for patients with dermatomyositis/polymyositis: a nationwide population-based retrospective cohort study.

OBJECTIVES: The aim of this study was to explore the possible association between dermatomyositis/polymyositis (DM/PM) and subsequent acute coronary syndrome (ACS) risk. METHOD: We used data from the National Health Insurance (NHI) system of Taiwan to address the research topic. The exposure cohort contained 2029 patients with new diagnoses of DM/PM. Each patient was randomly frequency-matched according to sex and age with four participants from the general population who did not have a history of ACS at the index date (control group). Cox proportional hazard regression analyses were conducted to estimate the relationship between DM/PM and subsequent ACS risk. RESULTS: Among patients with DM/PM, the overall risk for developing subsequent ACS was significantly higher than that of the control group [adjusted hazard ratio (aHR) 1.98, 95% confidence interval (CI) 1.17-3.35]. Further analysis indicated a higher risk in patients who were male, older, or diagnosed with comorbidities. CONCLUSIONS: The findings from this population-based retrospective cohort study suggest that DM/PM is associated with an increased subsequent ACS risk.

Cardiologist service volume, percutaneous coronary intervention and hospital level in relation to medical costs and mortality in patients with acute myocardial infarction: a nationwide study.

BACKGROUND: We explore whether cardiologist service volume, hospital level and percutaneous coronary intervention (PCI) are associated with medical costs and acute myocardial infarction (AMI) mortality. METHODS: From the 1997-2010 Taiwan National Health Insurance Research Database of the National Health Research Institute, we identified AMI patients and performed multiple regression analyses to explore the relationships among the different hospital levels and treatment factors. RESULTS: We identified 2942 patients with AMI in medical centers and 4325 patients with AMI in regional hospitals. Cardiologist service volume, performing PCI and medical costs per patient were higher in medical centers than in regional hospitals (P < 0.0001). However, the two hospital levels did not differ significantly in in-hospital mortality (P = 0.1557). Post hoc analysis showed significant differences in in-hospital mortality rate and in medical costs among the eight groups subdivided on the basis of hospital level, cardiologist service volume, and whether PCI was performed (P < 0.001 and P = 0.001, respectively). CONCLUSIONS: These results highlight the importance of encouraging hospitals to develop PCI capability and increase their cardiologist service volume after taking medical costs into account. Transferring AMI patients to hospitals with higher cardiologist service volume and PCI performed can also be very important.

Developing comprehensive and Brief ICF core sets for morbid obesity for disability assessment in Taiwan: a preliminary study.

BACKGROUND: The International Classification of Functioning, Disability, and Health (ICF) provides a framework for measuring functioning and disability based on a biopsychosocial model. AIM: The aim of this study was to develop comprehensive and brief ICF core sets for morbid obesity for disability assessment in Taiwan. DESIGN: Observational SETTING: Other POPULATION: Twenty-nine multidisciplinary experts of ICF METHODS: The questionnaire contained 112 obesity-relevant and second-level ICF categories. Using a 5-point Likert scale, the participants rated the significance of the effects of each category on the heath status of people with obesity. Correlation between an individual's score and the average score of the group indicated consensus. The categories were selected for the comprehensive core set for obesity if more than 50% of the experts rated them as "important" in the third round of the Delphi exercise, and for the brief core set if more than 80% of the experts rated them "very important." RESULTS: Twenty-nine experts participated in the study. These included 18 physicians, 4 dieticians, 3 physical therapists, 2 nurses, and 2 ICF experts. The comprehensive core set for morbid obesity contained 61 categories. Of these, 26 categories were from the component body function, 8 were from body structure, 18 were from activities and participation, and 9 were from environmental factors. The brief core set for obesity disability contained 29 categories. Of these, 19 categories were from the component body function, 3 were from body structure, 6 were from activities and participation, and one was from environmental factors. The comprehensive and brief ICF core sets provide comprehensive information on the health effects of morbid obesity and concise information for clinical practice. CONCLUSION: Comprehensive and brief core sets were created after three rounds of Delphi technique. Further validation study of these core sets by applying to patients with morbid obesity is needed. CLINICAL REHABILITAITON IMPACT: The comprehensive ICF core set for morbid obesity provides comprehensive information on the health effects of morbid obesity; the brief core set can provide concise information for clinical practice.

Sinus node dysfunction as an initial presentation of adult systemic lupus erythematosus.

Cardiac involvement in systemic lupus erythematosus (SLE) has been well described. However, sinus node involvement with profound sinus bradycardia as an early manifestation of adult SLE has not been reported. A 27-year-old previously healthy female was admitted due to intermittent fever for 4 days. SLE was diagnosed based on clinical manifestations and laboratory data. Profound sinus bradycardia (heart rate = 41/min) with weakness was noted during hospitalization. ECG abnormalities completely resolved after a high-dose intravenous steroid infusion. Sinus node involvement with significant bradycardia is one of the possible complications in the early stage of adult SLE. Close cardiovascular monitoring and serial ECGs are suggested for early detection of this serious complication of adult SLE.
