question:
In RA, conflicting results have been described on the association between genotypes of the complement factor mannose-binding lectin (MBL) and disease susceptibility and severity. This might be due to underpowerment of previous research work and the fact that no confirmation cohorts were used. Therefore a different approach is warranted.', 'MBL2 gene polymorphisms were determined in two RA cohorts (378 and 261 cases) and 648 controls. Considering MBL polymorphisms, cases and controls were categorized in groups of high, intermediate and low MBL production. The total sample size allows detection of a potential association between RA susceptibility and MBL groups with an odds ratio of 1.37 (alpha < 0.05; 1-beta > 0.8). Disease severity as defined by the need for anti-TNF therapy was also analysed for possible associations with MBL groups.', 'There was no difference in the frequencies between MBL genotypes of RA cases and controls that are associated with high (cases 54.4%, controls 57.0%), intermediate (cases 28.9%, controls 27.5%) or low (cases 16.7%, controls 15.5%) MBL production. Furthermore, there was no association between MBL groups and disease severity.

question:
Anxiety disorders increase risk of future cardiovascular disease (CVD) and mortality, even after controlling for confounds including smoking, lifestyle, and socioeconomic status, and irrespective of a history of medical disorders. While impaired vagal function, indicated by reductions in heart rate variability (HRV), may be one mechanism linking anxiety disorders to CVD, prior studies have reported inconsistent findings highlighting the need for meta-analysis.', 'Studies comparing resting-state HRV recordings in patients with an anxiety disorder as a primary diagnosis and healthy controls were considered for meta-analysis.', "Meta-analyses were based on 36 articles, including 2086 patients with an anxiety disorder and 2294 controls. Overall, anxiety disorders were characterized by lower HRV [high frequency (HF): Hedges' g\u2009=\u2009-0.29. 95% CI: -0.41 to -0.17, p\u2009<\u20090.001; time domain: Hedges' g\u2009=\u2009-0.45, 95% CI: -0.57 to -0.33, p\u2009<\u20090.001] than controls. Panic disorder (n\u2009=\u2009447), post-traumatic stress disorder (n\u2009=\u2009192), generalized anxiety disorder (n\u2009=\u200968), and social anxiety disorder (n\u2009=\u200990), but not obsessive-compulsive disorder (n\u2009=\u200940), displayed reductions in HF HRV relative to controls (all ps\u2009<\u20090.001).

question:
A metaanalysis was performed to investigate the association between serum osteopontin (OPN) levels and the clinical pathological features in non-small cell lung cancer (NSCLC) patients.', 'A systematic literature search was performed to identify relevant studies published prior to September 2014 using PubMed and China National Knowledge Infrastructure databases. Data extracted from the selected studies were analyzed using statistical software.', 'Based on our stringent selection criteria only 10 studies contained a combined total of 1,135 NSCLC patients. Our metaanalysis results clearly showed a strong correlation between serum OPN levels and multiple tumor parameters, such as TNM stage, histologic grade, and lymph node metastasis in NSCLC (TNM stage: RR = 0.69, 95% CI 0.62-0.77, p < 0.001; histologic grade: RR = 1.24, 95% CI 1.04-1.48, p = 0.016; lymph node metastasis: RR = 1.69, 95% CI 1.48 - 1.93, p < 0.001).
