Association between metabolic and bariatric surgery and malignancy: a systematic review, meta-analysis, trends, and conclusions

Conclusion: According to the data retrieved from patients who underwent MBS compared to nonoperated patients suffering from obesity, the overall risk for malignancy was lower in the MBS group. Additional information collected in this study revealed the behavior of specific types of cancer in response to induced weight loss by operative means. The benefit of surgery in patients suffering from obesity is not restricted to the improvement of obesity morbidity alone.

Characteristics and heterogeneity of schizoaffective disorder compared with unipolar depression and schizophrenia - a systematic literature review and meta-analysis

Conclusion: Regarding unipolar affective disorder this study confirms what we have shown for bipolar disorders in earlier studies: schizoaffective disorder falls between schizophrenia and affective disorders, and there are relevant quantitative differences in key illness characteristics, which supports the validity of the schizoaffective disorder concept. Contrary to our expectations heterogeneity is not larger in SAD than in UD and not substantially higher than in S. Lower reliability of the diagnosis of SAD therefore cannot be ascribed to higher variability of illness characteristics in SAD.
