Review Meta Analysis
Meta-analysis of microsatellite instability in relation to clinicopathological characteristics and overall survival in gastric cancer.
Several associations between microsatellite instability (MSI) and other clinicopathological factors have been reported in gastric cancer, but the results have been ambiguous. This systematic review and meta-analysis investigated the relationship between MSI and overall survival and clinicopathological characteristics of patients with gastric cancer. ⋯ MSI in gastric cancer was associated with good overall survival, reflected in several favourable clinicopathological tumour characteristics.

Review Meta Analysis Comparative Study
Meta-analysis of metabolic surgery versus medical treatment for microvascular complications in patients with type 2 diabetes mellitus.
This study aimed to examine the effect of metabolic surgery on pre-existing and future microvascular complications in patients with type 2 diabetes mellitus (T2DM) in comparison with medical treatment. Although metabolic surgery is the most effective treatment for obese patients with T2DM regarding glycaemic control, it is unclear whether the incidence or severity of microvascular complications is reduced. ⋯ In patients with T2DM, metabolic surgery prevented the development of microvascular complications better than medical treatment . Metabolic surgery improved pre-existing diabetic nephropathy compared with medical treatment.

Multiple surgical procedures in a single patient are relatively common and lead to dependent (clustered) data. This dependency needs to be accounted for in study design and data analysis. A systematic review was performed to assess how clustered data were handled in inguinal hernia trials. The impact of ignoring clustered data was estimated using simulations. ⋯ Clustering was rarely considered in inguinal hernia trials. The simulations underline the importance of considering clustering as part of the statistical analysis to avoid false-positive and false-negative results, and hence inappropriate study conclusions.

Long-term quality of life (QoL) after liver resection is becoming increasingly important, as improvements in operative methods and perioperative care have decreased morbidity and mortality rates. In this study, postoperative QoL after resection of benign or malignant liver tumours was evaluated. ⋯ This study confirmed overall good QoL in patients undergoing liver resection for benign or malignant tumours, which improved after surgery. Benign diseases were associated with better short- and long-term QoL scores.

The aim of this study was to evaluate absolute mortality risks and to determine whether changes in mortality risk occurred in patients with intermittent claudication (IC) or critical limb ischaemia (CLI) in the Netherlands between 1998 and 2010. ⋯ The risk of premature death in patients with IC and CLI declined significantly in the Netherlands, in a sex-specific manner, over the period from 1998 to 2010. The absolute risk of cardiovascular mortality remains high in these patients.
