Review Meta Analysis
Meta-analysis of postoperative mortality after elective repair of abdominal aortic aneurysms detected by screening.
The aim of this study was to compare the mortality rate within 30 days of elective surgery for abdominal aortic aneurysm (AAA) in men randomized to an invitation for ultrasound screening with that of men in the control group, whose aneurysms were detected incidentally. ⋯ The offer of screening identifies men whose early survival following elective AAA repair is better than that of men with an AAA detected incidentally.

Multicenter Study
Logistic risk model for mortality following elective abdominal aortic aneurysm repair.
The aim was to develop a multivariable risk prediction model for 30-day mortality following elective abdominal aortic aneurysm (AAA) repair. ⋯ This multivariable model for predicting 30-day mortality following elective AAA repair can be used clinically to calculate patient-specific risk and is useful for case-mix adjustment. The model predicted well across all risk groups in the validation data set.

Radical surgery is the de facto treatment for early rectal cancer. Conservative surgery with transanal endoscopic microsurgery can achieve high rates of cure but the histopathological measures of outcome used to select local treatment lack precision. Biomarkers associated with disease progression, particularly mesorectal nodal metastasis, are urgently required. The aim was to compare patterns of gene-specific hypermethylation in radically excised rectal cancers with histopathological stage. ⋯ Locus-specific hypermethylation was more prevalent in early- than late-stage disease. Hypermethylation of two or more of a panel of five tumour suppressor genes was associated with localized disease.
