Objectives: Stress and burn-out among surgical trainees has been reported most prevalent in core surgical trainees (CST) and female trainees in particular. This study aimed to identify factors perceived by CSTs to be associated with stress and burnout in those at risk.

Design: An open-ended questionnaire was distributed to 79 CSTs and two researchers categorised responses independently, according to Michie's model of workplace stress.

Aims: Unity of effort is an important component of strategic leadership and management theory associated with Core Surgical Training (CST) outcome. The aim was to determine the impact of team diversity on task completion: a creative design challenge, during CST Boot camp.

Methods: Attendees (n = 44) at a single Statutory Education Body's CST Boot camp were stratified into teams related to specialty theme, and set a design challenge as described by Peter Skillman, to build the tallest free-standing tower out of spaghetti (20 pieces), tape (1 m), and string (1 m), with a marshmallow on top in 18 minutes.

Histological 'phenotypic subtypes' that classify patients into four groups (immune, canonical, latent and stromal) have previously been demonstrated to stratify survival in a stage I-III colorectal cancer (CRC) pilot cohort. However, clinical utility has not yet been validated. Therefore, this study assessed prognostic value of these subtypes in additional patient cohorts along with associations with risk of recurrence and response to chemotherapy.

This study aimed to quantify core surgical trainee (CST) differential attainment (DA) related to three cohorts; white UK graduate (White UKG) versus black and minority ethnic UKG (BME UKG) versus international medical graduates (IMGs). The primary outcome measures were annual review of competence progression (ARCP) outcome, intercollegiate Membership of the Royal College of Surgeons (iMRCS) examination pass and national training number (NTN) selection. Intercollegiate Surgical Curriculum Programme (ISCP) portfolios of 264 consecutive CSTs (2010-2017, 168 white UKG, 66 BME UKG, 30 IMG) from a single UK regional post graduate medical region (Wales) were examined.

Objective: This study aimed to quality assure Assigned Educational Supervisor (AES) reports, using UK Joint Committee on Surgical Training objective criteria, to evaluate contribution to Annual Review of Competence Progression.

Design: Consecutive 145 AES reports from 75 trainers regarding 68 Core Surgical Trainees were assessed from 9 hospitals (2 Tertiary centers [77 reports], 7 District General Hospitals [68 reports]). Reports were assessed by independent assessors based on free text related to performance mapped to curricular objectives, operative logbooks, and Clinical Supervisor reports, and overall summary grades assigned ranging from development required, adequate, good to excellent.

Background: Risk profile assessment and corrective interventions using optimisation of health status and prehabilitation represent an important strategy in the management of patients with a suspected cancer diagnosis.

Aim: To determine the feasibility of pre-treatment optimisation and prehabilitation commenced at index primary care consultation, to improve patients' preparation for treatment by maximising the time available.

Design & Setting: Between January 2015 and May 2016, 195 patients presenting to 12 GP practices were deemed eligible to enter the study, of which 189 (96.

Background: In colorectal cancer (CRC), BRAF mutations influence tumour progression. In mismatch repair-deficient (dMMR) tumours, BRAF mutations are associated with a good prognosis, whereas in MMR-competent tumours, they are detrimental. The differential expression of the downstream MAPK pathway members, which are constitutively activated in BRAF mutant patients, may account for these differences.

Background: Bibliometric analysis highlights the key topics and publications which have shaped the understanding and management of Gastric cancer. Here the 100 most cited manuscripts in the field of gastric cancer (GC) are analysed.

Methods: The Thomson Reuters Web of Science database with the search terms 'gastric cancer' or 'gastric carcinoma' or 'stomach cancer' or 'stomach carcinoma' or 'gastroscopy' was used to identify all English language full manuscripts for the study.
