The objective of this study was to estimate the subsequent cancer risk of women after receiving hysterosalpingography (HSG) by conducting a nationwide retrospective cohort study. We identified a study cohort of 4,371 patients who had had a HSG examination and a comparison cohort of 17,484 women without HSG examination between 1998 and 2005. Both cohorts were followed up with until the end of 2010 to measure the incidence of cancer. The risk of developing cancer for patients with HSG was assessed using the Cox proportional hazard model. In the multivariate analyses, the HSG cohort did not have a significantly greater risk of cancer (Hazard Ratio [HR] = 1.02, 95% CI = 0.79-1.31) than the non-HSG cohort. The HR was highest for genital cancer (HR = 1.32, 95% CI = 0.77-2.25), followed by urinary system cancer (HR = 1.11, 95% CI = 0.23-5.40), and abdominal cancer not involving the GU system (HR = 1.04, 95% CI = 0.53-2.03), all of which were non-significant elevations. The cancer incidence rates, especially that for urinary system cancer, were increased in the HSG cohort, but the increase in cancer incidence was small and not statistically significant.

Objective: The aim of this study is to investigate the association between acupuncture therapy and the risk of fracture in patient with osteoarthritis (OA). Design: The authors performed a 1:1 propensity score-matched cohort study to analyze patient with OA between January 1, 1997 and December 31, 2010 through the Taiwanese National Health Insurance Research Database. Patients who received acupuncture therapy from the initial date of diagnosis of OA to December 31, 2010 were included in the acupuncture cohort. Patients who did not receive acupuncture during the same follow-up period were defined as the no-acupuncture cohort. A Cox regression model was used to adjust for sex, age, comorbidities, prescription, and surgical experiences. Hazard ratios (HRs) were compared between the two cohorts. Results: A total of 3416 patients were identified after 1:1 propensity score matching. The patients had similar basic characteristics. In the final analysis, 292 patients in the acupuncture cohort (30.06 per 1000 person-years) and 431 patients in the no-acupuncture cohort (56.08 per 1000 person-years) developed fractures (adjusted HRs 0.57, 95% confidence interval 0.49-0.67). A reduced cumulative incidence of fracture was found in the acupuncture cohort (log-rank test, p < 0.001). The association between acupuncture and reducing the fracture incidence was independent of sex, comorbidities, drugs use, and surgical experiences. Conclusion: Their results revealed the association between acupuncture therapies and a reduced incidence of fracture development in patients with OA. This finding provides noteworthy ideas for further research. [ABSTRACT FROM AUTHOR]
