1Effect of β-blocker therapy in diabetic patients with stable coronary heart disease: a meta-analysis显示文摘Background β-blocker (BB) therapy is a cornerstone for the treatment of coronary heart disease (CHD).The evidence of the benefit from long-term BB therapy in diabetic patients with stable CHD is scarce.This meta-analysis summarizes the evidence relating to the BB therapy in diabetic patients with stable CHD.Methods A meta-analysis was performed according to PRISMA and MOOSE guidelines for reporting of systematic reviews of observational studies.PubMed,Embase,and Cochrane central were searched and two authors independently screened studies for eligibility.The quality of studies was assessed with the Newcastle Ottawa scale.The primary outcome of interest was all-cause mortality,cardiovascular (CV) mortality and major adverse cardiovascular events (MACE) in diabetic patients with and without BB therapy.A generic inverse variance model was used to pool odds ratio or hazards ratio from included studies to calculate the overall effect estimate.The significance threshold was set at P-value < 0.05.Heterogeneity was assessed by I2.Results Four non-randomized studies with 9515 participants were selected for the analyses.Four studies were post-hoc analyses of randomized controlled trials,and one article was an analysis of a nationally representative survey.In a fixed effects model,BB therapy in diabetic patients with stable CHD was found to be associated with increased risk of CV mortality,and MACE (27% and 32% respectively;P-value < 0.05) and was not associated with a reduction in all-cause mortality (HR 1.12;95% CI: 0.94–1.33;P-value = 0.22).Conclusion BB therapy in diabetic patients with stable CHD appears to be linked to higher mortality.Large randomized trials are needed in this population to confirm these findings.Aaqib H Malik Suchith Shetty Kausik Kar Ramzi El Accaoui 2019Journal of Geriatric Cardiology2019,16,3:7
2Feasibility of robotic assisted bladder sparing pelvic exenteration for locally advanced rectal cancer:A single institution case series显示文摘BACKGROUND Pelvic exenteration for locally advanced rectal cancer involving prostate has been performed via open surgery.Robotic pelvic exenteration offers benefits of better pelvic visualisation and dissection for bladder preserving prostatectomy with vesicourethral anastomosis,while achieving clear margins.AIM To determine the feasibility of robotic assisted bladder sparing pelvic exenteration.METHODS We describe robotic assisted pelvic exenteration in three cases of locally advanced rectal cancer involving prostate and seminal vesicles(SV).The da Vinci S robotic system was used.Robotic console was docked at left oblique position for abdominal phase and redocked to between the patient’s legs for pelvic phase.All three cases were performed fully robotically at Tan Tock Seng Hospital by colorectal and urological teams.RESULTS Case 1:67-year-old with low rectal tumour 3 cm from anal verge involving the prostate.He underwent neo-adjuvant chemoradiotherapy and robotic abdominoperineal resection with en-bloc prostatectomy.Case 2:66-year-old with low rectal tumour 3 cm from anal verge involving prostate and bilateral SV.He underwent neo-adjuvant chemoradiotherapy and robot assisted ultra-low anterior resection with coloanal anastomosis and en-bloc prostatectomy.Case 3:57-year-old with metachronous rectal tumour in the rectovesical pouch inseparable from the anterior mid rectum,prostate and bilateral SV.He underwent robot assisted ultra-low anterior resection with en-bloc prostatectomy.Bladder neck margin revealed cauterized tumour cells,and he underwent total cystectomy and ileal conduit creation.Histology revealed no residual tumour.All patients are currently disease free CONCLUSION Robot assisted bladder sparing pelvic exenteration can be safely performed in locally advanced rectal cancer with acceptable surgical outcome while preserving benefits of minimally invasive surgery.Nathaniel H Heah Kar Yong Wong 2020World Journal of Gastrointestinal Surgery2020,12,4:2
