Meta Analysis
Meta-analysis of diagnostic value of serum Carbohydrate antigen 199 in pancreatic cancer.
Carbohydrate antigen 199 (CA199) has been used as a new promising serum biomarker for the diagnosis of pancreatic cancer. But its utility was full of controversies. This study sought to determine the diagnosis value of serum CA199 in pancreatic cancer through enrolling all the related eligible studies. ⋯ The current analyses indicated that CA199 is a valuable marker in the diagnosis of pancreatic cancer.

Review Meta Analysis
Aspirin for the prevention of cardiovascular morbidity.
Aspirin (ASA) use for secondary prevention in patients with cardiovascular (CV) disease is well established through its beneficial effects on the reduction of myocardial infarction, ischemic stroke and CV mortality. This beneficial effect of ASA seems to consistently outweigh the risk in most patient subsets. Current guidelines endorse ASA for primary prevention of CV events in adults who are at moderate-high risk of CV morbidity. ⋯ The following manuscript describes the data emerging from contemporary trials regarding the efficacy and safety of ASA in various patient subsets. The authors propose certain strategies to enhance safety and efficacy in order to augment the beneficial effects of ASA along with other modalities of primary prevention for suitable candidates. When contemplating ASA prescription for primary prevention of CV events, physicians should carefully weigh the potential benefits of risk reduction versus likelihood of harm, mostly related to bleeding complications.

Review Meta Analysis
Prevalence and pathogenesis of osteoporosis in patients with inflammatory bowel disease.
Decreased bone mineral density is a frequent finding in patients with inflammatory bowel disease. Factors contributing to this are: 1) malabsorption of vitamin D, calcium and possibly vitamin K and other nutrients, 2) treatment with corticosteroids, 3) inflammatory cytokines in inflammatory bowel disease, and 4) hypogonadism induced by the inflammatory bowel disease. Among patients with Crohn's disease from 32% to 38% have osteopenia (Z-scores <-1), and among patients with ulcerative colitis 23% to 25% have osteopenia. ⋯ The observed excess fracture risk was limited compared to the general population in both Crohn's disease (RR=1.2, 95% CI: 0.9-1.6 for any fracture and 2.2, 95% CI: 1.2-4.0 for spine fractures) and ulcerative colitis (RR=1.1, 95% CI: 1-1.2 for any fracture, and 1.5, 95% CI: 0.9-2.5 for spine fractures). The observed excess fracture risk was close to that expected from the changes in BMD. Despite the limited excess fracture risk, a relatively large percentage of all fractures may be attributable to corticosteroid use among users of corticosteroids.
