Tea consumption and the risks of osteoporosis and hip fracture: a population-based longitudinal follow-up study.

This population-based longitudinal follow-up study showed a protective effect of tea consumption against osteoporosis, particularly among women and middle-aged people. High tea consumption was also associated with a reduced risk of hip fracture. INTRODUCTION: To investigate the association of tea consumption with the risks of osteoporosis and hip fracture. METHODS: This study used the Keelung Community-based Integrated Screening database and Taiwan's National Health Insurance Research Database. A total of 42,742 subjects aged 45 to 74 years were enrolled. Each was classified as no tea consumption, low tea consumption, and high tea consumption, according to the results of an eating habits questionnaire. The diagnosis of osteoporosis and hip fracture was based on BMD measured by dual-energy X-ray absorptiometry and the X-ray findings. The median follow-up time was 8.5 years. RESULTS: As compared with the no tea consumption group, the osteoporosis HRs for the low tea consumption and high tea consumption groups were 0.88 (95% confidence interval (CI) 0.80-0.96) and 0.87 (95% CI 0.80-0.94), respectively. Among those participants aged 59 or below, the osteoporosis HRs for low tea consumption and high tea consumption (vs. no tea consumption) were 0.85 (95% CI 0.74-0.96) and 0.79 (95% CI 0.69-0.90). The HRs of hip fracture for the low tea consumption and high tea consumption groups (vs. no tea consumption) were 0.85 (95% CI 0.67-1.08) and 0.69 (95% CI 0.55-0.86), respectively. CONCLUSION: Tea consumption was linked to a lower risk of osteoporosis, particularly among women and middle-aged people. High tea consumption was also associated with a reduced risk of hip fracture.

Osteoporosis and the long-term risk of peripheral artery disease: a population-based longitudinal follow-up study in Taiwan.

INTRODUCTION: Osteoporosis has been linked to atherosclerotic diseases such as coronary heart disease and ischemic stroke. However, the relationship between osteoporosis and peripheral artery disease (PAD) has not been investigated. This study aims to evaluate the risk of PAD in patients with osteoporosis and the impact of sex on this association. METHODS: This population-based study used the Longitudinal Health Insurance Database 2005, a subset of Taiwan's National Health Insurance research database. A total of 54,324 individuals between 40 and 79 years old were included in this study. The osteoporosis group (n = 27,162) consisted of patients with a diagnosis of osteoporosis between January 1, 2002, and December 31, 2006, while the non-osteoporosis group were patients without osteoporosis selected by stratified random sampling (n = 27,162). The primary outcome was the occurrence of newly diagnosed PAD. Cox proportional hazard regression modeling was used to evaluate the association between osteoporosis and the risk of PAD, with adjustment for the baseline characteristics. RESULTS: The risk of PAD for the osteoporosis group was 28% higher than for the non-osteoporosis group (adjusted hazard ratio (HR) 1.28, 95% confidence interval [CI] 1.20-1.36, p < 0.001), and the PAD-free survival rate was lower in the osteoporosis group (p < 0.001). Sex-stratified analysis revealed a similar HR magnitude between osteoporotic men (HR 1.36; 95% CI 1.19-1.57) and women (HR 1.25; 95% CI 1.17-1.35), compared with their non-osteoporotic counterparts. CONCLUSION: This study found an increased long-term risk of PAD in both men and women with osteoporosis. Osteoporosis has been associated with increased risks of atherosclerotic diseases. However, the relationship between osteoporosis and peripheral artery disease remains uncertain. The present population-based longitudinal follow-up study showed that patients with osteoporosis are at an increased risk of developing peripheral artery disease.

Does Surgery Reduce the Risk of Complications Among Patients with Multiple Rib Fractures? A Meta-analysis.

BACKGROUND: Multiple rib fractures are common in trauma patients, who are prone to trauma-associated complications. Surgical or nonsurgical interventions for the aforementioned conditions remain controversial. QUESTIONS/PURPOSES: The purpose of our study was to perform a meta-analysis to evaluate the clinical prognosis of surgical fixation of multiple rib fractures in terms of (1) hospital-related endpoints (including duration of mechanical ventilation, ICU length of stay [LOS] and hospital LOS), (2) complications, (3) pulmonary function, and (4) pain scores. METHODS: We screened PubMed, Embase, and Cochrane databases for randomized and prospective studies published before January 2018. Individual effect sizes were standardized; the pooled effect size was calculated using a random-effects model. Primary outcomes were duration of mechanical ventilation, intensive care unit length of stay (ICU LOS), and hospital LOS. Moreover, complications, pulmonary function, and pain were assessed. RESULTS: The surgical group had a reduced duration of mechanical ventilation (weighted mean difference [WMD], -4.95 days; 95% confidence interval [CI], -7.97 to -1.94; p = 0.001), ICU LOS (WMD, -4.81 days; 95% CI, -6.22 to -3.39; p < 0.001), and hospital LOS (WMD, -8.26 days; 95% CI, -11.73 to -4.79; p < 0.001) compared with the nonsurgical group. Complications likewise were less common in the surgical group, including pneumonia (odds ratio [OR], 0.41; 95% CI, 0.27-0.64; p < 0.001), mortality (OR, 0.24; 95% CI, 0.07-0.87; p = 0.030), chest wall deformity (OR, 0.02; 95% CI. 0.00-0.12; p < 0.001), dyspnea (OR, 0.23; 95% CI, 0.09-0.54; p < 0.001), chest wall tightness (OR, 0.11; 95% CI, 0.05-0.22; p < 0.001) and incidence of tracheostomy (OR, 0.34; 95% CI, 0.20-0.57; p < 0.001). There were no differences between the surgical and nonsurgical groups in terms of pulmonary function, such as forced vital capacity (WMD, 6.81%; 95% CI: -8.86 to 22.48; p = 0.390) and pain scores (WMD, -11.41; 95% CI: -42.09 to 19.26; p = 0.470). CONCLUSIONS: This meta-analysis lends stronger support to surgical fixation, rather than conservative treatment, for multiple rib fractures. Nevertheless, additional trials should be conducted to investigate surgical indications, timing, and followup for quality of life. LEVEL OF EVIDENCE: Level I, therapeutic study.
