Tamoxifen is widely used for hormone-sensitive breast cancer, achieved by modulating the estrogen receptor activity in a tissue-specific manner. There is evidence to support the protective effects of estrogen against Parkinson's disease (PD), a common neurodegenerative condition. Some epidemiologic studies suggest the use of tamoxifen may modulate the PD risk. We conducted a meta-analysis to examine the association between tamoxifen and risk of PD. ⋯ Our meta-analysis suggests that tamoxifen use may be associated with an increased PD risk in women. However, due to heterogeneity and potential limitations of some of the studies, further clinical and functional validation will be needed. Longitudinal studies supported by imaging and biomarkers evaluation will be useful to identify the mechanisms linking tamoxifen and PD risk.

Effect of serum uric acid and gout on the incidence of colorectal cancer: A meta-analysis.
Pathogenesis of colorectal cancer (CRC) depends on multiple factors. Identifying risk factors for CRC may facilitate the early prevention of the disease. We aimed to assess whether existing evidence suggests that serum uric acid (SUA) levels and gout are associated with CRC incidence. ⋯ Both SUA level and gout were associated with an increased risk of CRC. Maintaining low SUA levels may be beneficial in reducing the incidence of CRC. Further studies evaluating the precise mechanisms underlying this association are needed to establish whether SUA/gout causes CRC.

Association of C-reactive protein level with adverse outcomes in patients with atrial fibrillation: A meta-analysis.
Studies on the association between C-reactive protein (CRP) level and poor outcomes have been yielded controversial results in patients with atrial fibrillation (AF). This meta-analysis sought to investigate the utility of elevated CRP level in predicting adverse outcomes in AF patients. ⋯ Elevated CRP level may be an independent predictor of all-cause mortality, stroke, and MACEs in patients with AF. CRP level at baseline can provide important prognostic information in risk classification of AF patients.

Nosocomial vs Healthcare associated vs Community acquired Spontaneous Bacterial Peritonitis: Network meta-analysis.
Spontaneous bacterial peritonitis (SBP) is a common complication in decompensated liver cirrhosis with ascitic fluid polymorphonuclear cell count > 250/mm3. Community acquired SBP (CA-SBP) occurs within the first 48 hours after hospital admission. Nosocomial SBP (N-SBP) occurs 48-72 hours after hospitalization. Healthcare associated SBP (HA-SBP) occurs in patients hospitalized in the preceding 90 days to months. We aim to evaluate mortality and resistance patterns to third generation cephalosporin among the three types. ⋯ Our network meta-analysis shows increased mortality and antibiotic resistance with nosocomial SBP. We recommend clearly identifying such patients to manage accordingly as well as developing guidelines geared towards nosocomial infections to be able to optimally steer resistance patterns and reduce mortality.

Systematic Review and Meta-Analysis of Church-based Interventions to Improve Cardiovascular Disease Risk Factors.
Church-based interventions have been shown to reduce cardiovascular disease (CVD) risk factors and could reduce health disparities in groups with a high burden of CVD. We aim to conduct a systematic review and meta-analysis to determine the effectiveness of church-based interventions for CVD risk factor improvement and to examine the types of interventions that are effective. ⋯ Church-based interventions targeting CVD risk factors are effective for reducing CVD risk factors, particularly in populations with health disparities. These findings can be used to design future church-based studies and programs to improve cardiovascular health.
