A Systematic Review to Summarise and Appraise the Reporting of Surgical Innovation: a Case Study in Robotic Roux-en-Y Gastric Bypass.

Robotic Roux-en-Y gastric bypass (RRYGB) is an innovative alternative to traditional laparoscopic approaches. Literature has been published investigating its safety/efficacy; however, the quality of reporting is uncertain. This systematic review used the Idea, Development, Exploration, Assessment and Long-term follow-up (IDEAL) framework to assess the reporting quality of available literature.

Techniques and Technologies to Improve Vein Graft Patency in Coronary Surgery.

Vein grafts are the most used conduits in coronary artery bypass grafting (CABG), even though many studies have suggested their lower patency compared to arterial alternatives. We have reviewed the techniques and technologies that have been investigated over the years with the aim of improving the quality of these conduits. We found that preoperative and postoperative optimal medical therapy and no-touch harvesting techniques have the strongest evidence for optimizing vein graft patency.

Surgical Ablation for Atrial Fibrillation During Mitral Valve Surgery: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Although surgical ablation has been shown to produce excellent outcomes at follow-up for patients with atrial fibrillation who underwent mitral valve replacement/repair (MVR), this procedure is not commonly performed. Our objective was to conduct a systematic review and meta-analysis to evaluate the outcomes of concomitant surgical ablation during MVR. Three databases were systematically reviewed for randomized clinical trials published by August 2022.

Validation of the German Registry for Acute Aortic Dissection Type A Score in predicting 30-day mortality after type A aortic dissection surgery.

Objectives: No reliable scores are available to predict mortality following surgery for type A acute aortic dissection (TAAAD). Recently, the German Registry of Acute Aortic Dissection Type A (GERAADA) score has been developed. We aim to compare how the GERAADA score performs in predicting operative mortality for TAAAD to the European System for Cardiac Operative Risk Evaluation (EuroSCORE) II.

Mineralocorticoid receptor antagonism in diabetes reduces albuminuria by preserving the glomerular endothelial glycocalyx.

The glomerular endothelial glycocalyx (GEnGlx) forms the first part of the glomerular filtration barrier. Previously, we showed that mineralocorticoid receptor (MR) activation caused GEnGlx damage and albuminuria. In this study, we investigated whether MR antagonism could limit albuminuria in diabetes and studied the site of action.

Females have an increased risk of short-term mortality after cardiac surgery compared to males: Insights from a national database.

Objectives: Female sex is considered a risk factor for mortality and morbidity following cardiac surgery. This study is the first to review the UK adult cardiac surgery national database to compare outcomes following surgical coronary revascularisation and valvular procedures between females and males.

Methods: Using data from National Adult Cardiac Surgery Audit, we identified all elective and urgent, isolated coronary artery by-pass grafting (CABG), aortic valve replacement (AVR) and mitral valve replacement/repair (MVR) procedures from 2010 to 2018.

A systematic review of robot-assisted anti-reflux surgery to examine reporting standards.

Robot-assisted anti-reflux surgery (RA-ARS) is increasingly being used to treat refractory gastro-oesophageal reflux disease. The IDEAL (Idea, Development, Exploration, Assessment, Long-term follow up) Collaboration's framework aims to improve the evaluation of surgical innovation, but the extent to which the evolution of RA-ARS has followed this model is unclear. This study aims to evaluate the standard to which RA-ARS has been reported during its evolution, in relation to the IDEAL framework.

Hybrid coronary revascularization versus coronary artery bypass grafting for multivessel coronary artery disease: A systematic review and meta-analysis.

Background: Hybrid coronary revascularization (HCR) combines the benefits of a left internal mammary artery to left anterior descending artery anastomosis, via a mini thoracotomy, with percutaneous coronary intervention (PCI) for other diseased coronaries.

Aims: The aim of this meta-analysis is to compare the short- and long-term outcomes of HCR with those of coronary artery bypass grafting (CABG) for multi-vessel coronary artery disease (MCAD).

Methods: We performed a meta-analysis with a primary outcome of short-term mortality and secondary outcomes of mid-term survival, length of hospital stay, stroke, renal failure and mid-term MACE rate.

Surgical outcomes of post-infarct ventricular septal defect repair: Insights from the UK national adult cardiac surgery audit database.

Objectives: Ventricular septal defect (VSD) is becoming a progressively less frequent mechanical complication of myocardial infarction (MI). However, this event is still associated with high operative mortality. We aimed to describe the trends and the risk factors associated with surgical VSD repair outcomes and to provide a clinical benchmark for percutaneous VSD closure strategies.

Daytime and outcomes after cardiac surgery: Systematic review and metaanalysis, insights from a large UK database review and post-hoc trial analysis.

Background: Several studies have suggested a variation of myocardial tolerance to ischaemia depending on the daytime of surgery. To test this hypothesis, we conducted a three-level analysis: metaanalysis, national patient-level dataset analysis and a post-hoc trial analysis.

Methods: We first performed a systematic review and metaanalysis of available studies comparing clinical outcomes following cardiac surgery performed in the morning (am) versus afternoon (pm).

Impact of sex on outcomes after cardiac surgery: A systematic review and meta-analysis.

Background: Despite advances in cardiac surgery, observational studies suggest that females have poorer post-operative outcomes than males. This study is the first to review sex related outcomes following both coronary artery bypass graft (CABG) and valve surgery with or without combined CABG.

Methods: We identified 30 primary research articles reporting either short-term mortality (in-hospital/30 day), long-term mortality, and post-operative stroke, sternal wound infection and myocardial infarction (MI) in both sexes following CABG and valve surgery with or without combined CABG.

Systematic review and meta-analysis of mortality risk prediction models in adult cardiac surgery.

Objectives: The most used mortality risk prediction models in cardiac surgery are the European System for Cardiac Operative Risk Evaluation (ES) and Society of Thoracic Surgeons (STS) score. There is no agreement on which score should be considered more accurate nor which score should be utilized in each population subgroup. We sought to provide a thorough quantitative assessment of these 2 models.

Aortic valve neocuspidization with autologous pericardium in adult patients: UK experience and meta-analytic comparison with other aortic valve substitutes.

Objectives: We sought to provide further evidence on the safety and efficacy of aortic valve neocuspidization (AVNeo) using autologous pericardium in adult patients with aortic valve disease by reporting clinical and echocardiographic results from the first UK experience and performing a meta-analytic comparison with other biological valve substitutes.

Methods: We reported clinical and echocardiographic outcomes of 55 patients (mean age 58 ± 15 years) undergoing AVNeo with autologous pericardium in 2 UK centres from 2018 to 2020. These results were included in a meta-analytic comparison between series on AVNeo (7 studies, 1205 patients, mean weighted follow-up 3.

Group V secretory phospholipase A2 enhances the progression of angiotensin II-induced abdominal aortic aneurysms but confers protection against angiotensin II-induced cardiac fibrosis in apoE-deficient mice.

Abdominal aortic aneurysms (AAAs) and heart failure are complex life-threatening diseases whose etiology is not completely understood. In this study, we investigated whether deficiency of group V secretory phospholipase A(2) (GV sPLA(2)) protects from experimental AAA. The impact of GV sPLA(2) deficiency on angiotensin (Ang) II-induced cardiac fibrosis was also investigated.

Outcome of dialectical behaviour therapy for concurrent eating and substance use disorders.

Aim: The current study examined the preliminary efficacy of dialectical behaviour therapy (DBT) adapted for concurrent eating disorders (EDs) and substance use disorders (SUDs).

Method: A matched randomized controlled trial was carried out with 25 female outpatients diagnosed with concurrent ED and SUD. Participants randomized to the intervention condition received DBT, whereas those randomized to the control condition received treatment as usual (TAU), both for a period of 1 year.
