Introduction

The biggest concerns in the current pandemic are enormous workload pressure, psychological distress, caregiver burnout, and, even worse, transmission of the virus among healthcare workers. One of the potentially beneficial tools in reducing the above-mentioned risks for overwhelming the healthcare system is telemedicine. Although the role of telemedicine and related interventions as a crisis management tool has increased, the current state of the implementation of telemedicine in surgery and surgical subspecialties has not been adequately evaluated.

Objective and significance

The objective of this review is to screen the literature, extract expert opinions, qualitative, and quantitative data on the current use and future directions in the implementation of telemedicine in surgery and surgical subspecialties during the COVID-19 pandemic. The findings would potentially help in understanding the challenges and future directions of telemedicine use in surgery.

Methods and analysis

The databases to be searched include PubMed, EMBASE, and MEDLINE (via Ovid). In addition, ClinicalTrials.gov and medRxiv.org will be searched for any ongoing and/or unpublished studies. The reference lists of articles included in the review will be screened to assess the sensitivity of the search. Literature search, quality assessment, followed by data extraction will be performed by two independent researchers. The findings of the data synthesis will be reported in diagrams, tables, and text. This review will consider reports that include expert opinions, qualitative and quantitative data on the implementation of telemedicine in surgery and surgical subspecialties (including patients with surgical disease of any age) during the COVID-19 pandemic. In addition, future perspectives reported based either on the evidence provided by the data or on expert opinions will be considered.

Ethics and dissemination

This study does not require an institutional review board approval given its summary design nature. Findings of this systematic review will be published in a peer-reviewed journal.

Systematic review registration number

PROSPERO does not currently accept registrations for scoping reviews, literature reviews or mapping reviews.

Introduction

Traditional carotid endarterectomy is considered to be the standard technique for prevention of a new stroke in patients with a symptomatic carotid stenosis. Use of plexus anesthesia or general anesthesia in traditional carotid endarterectomy is, to date, not unequivocally proven to be superior to one other. A systematic review is needed for evaluation of benefits and harms to determine which technique, plexus anesthesia or general anesthesia is more effective for traditional carotid endarterectomy in patients with symptomatic carotid stenosis.

Methods and outcomes

The review will be conducted according to this protocol following the recommendations of the ‘Cochrane Handbook for Systematic Reviews’ and reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Randomized Clinical Trials comparing plexus anesthesia versus general anesthesia in traditional carotid endarterectomy will be included. Primary outcomes will be postoperative death and/ or stroke (<30 days) and serious adverse events. Secondary outcomes will be non-serious adverse events.

We will primarily base our conclusions on meta-analyses of trials with overall low risk of bias. We will use Trial Sequential Analysis to assist the evaluation of imprecision in Grading of Recommendations Assessment, Development and Evaluation. However, if pooled point-estimates of all trials are similar to pooled point-estimates of trials with overall low risk of bias and there is lack of a statistical significant interaction between estimates from trials with overall high risk of bias and trials with overall low risk of bias we will consider the Trial Sequential Analysis adjusted confidence interval precision of the estimate achieved in all trials as the result of our meta-analyses.

Ethics and dissemination

The proposed systematic review will collect and analyze secondary data from already performed studies therefore ethical approval is not required. The results of the systematic review will be disseminated by publication in a peer-review journal and submitted for presentation at relevant conferences.

Introduction

Surgical site infections (SSIs) following groin incision for arterial exposure are commonplace and a significant cause of morbidity and mortality following major arterial surgery. Published incidence varies considerably. The primary aim of GIVE will be to compare individual units’ practice with established guidelines from The National Institute for Health and Care Excellence (NICE). Secondary aims will be to describe the contemporary rate of SSI in patients undergoing groin incision for arterial exposure, to identify risk factors for groin wound infection, to examine the value of published tools in the prediction of SSI, to identify areas of equipoise which could be examined in future efficacy/effectiveness trials and to compare UK SSI rates with international centres.

Methods and analysis

This international, multicentre, prospective observational study will be delivered via the Vascular and Endovascular Research Network (VERN). Participating centres will identify all patients undergoing clean emergency or elective groin incision(s) for arterial intervention during a consecutive 3-month period. Follow up data will be captured at 90 days after surgery. SSIs will be defined according to the Centres for Disease Control and Prevention (CDC) criteria. Data will be gathered centrally using an anonymised electronic data collection tool or secure email transfer.

Ethics and dissemination

This study will be registered as a clinical audit at all participating UK centres; research ethics approval is not required. National leads will oversee the appropriate registration and approvals in countries outside the UK as required. Site specific reports of SSI rates will be provided to each participating centre. Study results will be disseminated locally at each site, publicised on social media and submitted for peer-reviewed publication.

Introduction

The most common type of leukemia is acute myeloid leukemia (AML) with the lowest survival rate among all of the leukemias particularly in adults. The evidence has shown that dysregulation of miRNA expression is associated with AML. Therefore, the aim of this systematic review was to clarify the role of miR-181a expression in AML.

Methods and analysis

In the present study, observational studies of the roles of miR-181a expression in patients with AML will be included. Standards and indicators test should be performed for all patients. We will search PubMed, SCOPUS and ISI Web of Science with no restriction of language. The outcomes will be reviewed for association between miR-181a level and AML progression and the strength of this relationship with AML will be investigated. Selection of articles and data extraction will be performed by two independent reviewers. STROBE will be used for assessment of study quality. Publication bias and data synthesis will be an assessment by funnel plots and Beggs and Egger’s tests using Stata software V.12.1.

Ethics and dissemination

There are no ethical issues.

Trial registration number

This systematic review protocol is registered in the PROSPERO (International Prospective Register of Systematic Reviews), and registration number CRD42016040080.

Introduction

Closure of mesenteric defects during laparoscopic Roux-en-Y gastric bypass surgery (RYGB) has not been fully established as standard operative practice. However, in recent years a body of evidence has emerged suggesting that non-closure of defects leads to increased rates of internal herniation and its potential consequences, including the need for reoperation, along with an associated morbidity and mortality risk. Within the emerging literature there has also been some evidence of a greater risk of 30-day complications in closure groups. This systematic review and meta-analysis aims to look at the existing evidence and provide guidance on whether closure of mesenteric defects should be standard operative practice.

Methods

The systematic review and meta-analysis has been registered a priori. A literature search will be performed interrogating the Medline and Embase databases via Ovid, and also the Cochrane Controlled Register of Trials (CENTRAL), to identify randomised and non-randomised studies reporting comparative outcomes following closure vs. non-closure of mesenteric defects during RYGB. The primary outcome will be reoperation for small bowel obstruction, and secondary outcomes will include internal herniation, jejuno-jejunal anastomosis narrowing or kinking, adhesions, complications (<30 days and >30 days after surgery), 30-day mortality, reoperation, and any other outcome deemed relevant and reported in more than one study.

Introduction

The National Research Collaborative Meeting (NRCM) 2017 was jointly hosted between the West Midlands Research Collaborative (WMRC) and Student Audit and Research in Surgery (STARSurg) on 30th November 2017 in Birmingham. The NRCM 2017 theme was ‘Challenging Traditional Research’.

Methods

Narrative review, outlining key challenges and recommendations for trainee collaborative research groups across medical and surgical disciplines based on the core themes from the NRCM 2017 meeting.

Results

Core themes of: (1) surgical oncology trials; (2) placebo-controlled surgical trials; (3) research funding; (4) medical student involvement in research; (5) emergency care; (6) patient and public involvement. Recommendations were made for planning future collaborative studies, based on these topic areas.

Conclusions

The collaborative research model has demonstrated longevity and effectiveness in delivering high-quality, practice-changing research both within the NHS and internationally. Learning between groups and highlighting areas for interdisciplinary collaboration will drive a meaningful, patient-centred agenda for the future.
