Background: Poor mental health in medical students is a global concern. Effective interventions are required, which are tailored towards the training-related stressors medical students experience. The Reboot coaching programme is an online, tailored intervention based on cognitive-behavioural principles.

Aims: To evaluate whether the Reboot coaching programme tailored for medical students was feasible and associated with improvements in mental health outcome indicators.

Methods: Medical students participated in two group online workshops and a one-to-one coaching call with a Reboot-trained licensed psychological therapist. Participants provided data at: baseline (T1), post-workshops (T2), post-coaching call (T3) and 4-month follow-up (T4). Outcome measures included resilience, confidence, burnout and depression. Feedback was provided regarding the workshops at T2.

Results: 115 participants (93/80.9% women; mage = 23.9; SD = 2.8) were recruited, 83 (72.2%) completed all intervention elements and 82 (71.3%) provided T4 data, surpassing recruitment and retention targets. There were significant improvements following baseline in resilience (ps < .001), confidence (ps < .001), burnout (ps < .001) and depression (ps ≤ .001). Most participants agreed the workshops imparted useful skills (n = 92; 99%) and would recommend Reboot to others (n = 89; 95.6%).

Conclusions: Existing interventions have produced mixed results regarding their effectiveness in improving medical students' mental health. Reboot is a feasible intervention in this group which is associated with improvements in resilience, confidence, burnout and depression. Further controlled studies of Reboot are now needed.

Background: Cardiovascular disease affects over 7 million people in the UK and statins are often prescribed to mitigate cardiovascular risks. The effect of statins on a number of cancers is debated and their effect on Bacillus Calmette-Guérin (BCG) responsiveness in non-muscle invasive urinary bladder cancer (NMIBC) is not fully understood.

Aims: This study aims to explore the difference in HMG Co-A reductase (HMGCR) expression in NMIBC on immunochemistry in BCG responders and non-responders while on statins.

Method: Three hundred and thirty-two cases of intravesical BCG treatment for high-risk NMIBC between November 2003 and December 2017 were identified. Patients taking statins for at least 12 months before the diagnosis of NIMBC and with a follow-up of at least 5 years were included. They were divided into BCG responders and non-responders. Tumour tissue from these patients was immunohistochemically stained and quantitative image analysis carried out to assess and compare HMGCR expression in the groups.

Results & conclusion: This study showed a differential expression of HMGCR in responders vs. non-responders to BCG for high-risk NMIBC on statins. This data should form the basis of a further research and multi-centre study in a larger cohort, using HMGCR as a biomarker of response in patients on statins.

Introduction: The updated Bosniak classification in 2019 (v2019) addresses vague imaging terms and revises the criteria with the intent to categorise a higher proportion of cysts in lower-risk groups and reduce benign cyst resections. The aim of the present study was to compare the diagnostic accuracy and inter-observer agreement rate of the original (v2005) and updated classifications (v2019).

Method: Resected/biopsied cysts were categorised according to Bosniak classifications (v2005 and v2019) and the diagnostic accuracy was assessed with reference to histopathological analysis. The inter-observer agreement of v2005 and v2019 was determined.

Results: The malignancy rate of the cohort was 83.6% (51/61). Using v2019, a higher proportion of malignant cysts were categorised as Bosniak ≥ III (88.2% vs 84.3%) and a significantly higher percentage were categorised as Bosniak IV (68.9% vs 47.1%; p = 0.049) in comparison to v2005. v2019 would have resulted in less benign cyst resections (13.5% vs 15.7%). Calcified versus non-calcified cysts had lower rates of malignancy (57.1% vs 91.5%; RR,0.62; p = 0.002). The inter-observer agreement of v2005 was higher than that of v2019 (kappa, 0.70 vs kappa, 0.43).

Discussion: The updated classification improves the categorisation of malignant cysts and reduces benign cyst resection. The low inter-observer agreement remains a challenge to the updated classification system.

Objectives: We aimed to determine whether inflammatory indexes (II), including the neutrophil-lymphocyte ratio (NLR), the C-reactive protein (CRP) to albumin ratio (CAR), the CRP-lymphocyte ratio (CLR), and the systemic immune-inflammation index (SIII) can be diagnostic for common bile duct stones (CBDSs) excretion before endoscopic retrograde cholangiopancreatography (ERCP).

Backgrounds: Because of the spontaneous clearance, it is mandatory to ascertain the presence of CBDSs before ERCP.

Methods: Retrospectively, we evaluated two groups. Group A included 96 records in which CBDSs existed in magnetic resonance cholangiopancreatography (MRCP) and ERCP. Group B included 36 records in which CBDSs existed in MRCP but not ERCP. IIs were calculated on presentation and before ERCP.

Results: Stone detection in ERCP had a 3.992-fold (95% 1.769-9.007) higher probability with a stone larger than 3.25 mm in MRCP. Before ERCP, CAR, and CLR values were higher in group A than in group B (3.88 [1.25-14.14] and 1.24 [0.50-9.66], p = 0.027 versus 8.79 [2.19-35] and 2.67 [1.02-20.05], p = 0.029, respectively). Higher CRP, CAR, and CLR values were considered significant for detecting a stone in ERCP (AUC: 0.627 [0.519-0.739], 0.625 [0.513-0.737], and 0.624 [0.514-0.734], respectively).

Conclusion: Low CRP, CAR, and CLR values might associate with the spontaneous migration of CBDS.

Background: The "weekend" effect resulting in increased complication rates in patients admitted on weekends has been noted in many diseases.

Objective: This systematic review and meta-analysis aimed to collate adjusted data from published studies to assess if admission on weekends as compared to weekdays increases mortality rates in hip fracture patients.

Methods: Databases of PubMed, CENTRAL, Scopus, Web of Science, and Embase were searched up to 31^st December 2022 for studies comparing mortality between weekend versus weekday admission of hip fracture patients. Adjusted hazard ratios (HR) were pooled.

Results: Fourteen studies including 1,487,986 patients were analyzed. Most studies were from Europe and North America. Results showed no difference in mortality rates of hip fracture patients admitted on weekends versus weekdays (HR: 1.00 95% 0.96, 1.04 I²= 75%). There was no publication bias and results did not change on the leave-one-out analysis. Subgroup analysis based on sample size and treatment did not change outcomes.

Conclusion: This meta-analysis has shown no apparent weekend effect in cases of hip fractures. Patients admitted on weekends had similar mortality rates as compared to those admitted on weekdays. Current data has high heterogeneity and is mostly from developed countries.

Objective: To summarize recent findings on the association of low skeletal muscle mass and muscle quality with overall survival and recurrence-free survival in patients with pancreatic cancer.

Methods: A systematic search was conducted using Medline (via PubMed), Embase and Scopus databases for observational studies reporting on the overall survival and recurrence-free survival. Pooled effect sizes were reported as hazards ratio along with 95% confidence intervals.

Results: A total of 34 studies were included. Low skeletal muscle index (indicating muscle mass) was associated with poor overall survival (hazards ratio: 1.50; 95% confidence interval: 1.34, 1.67) and lower recurrence-free survival (hazards ratio: 1.28, 95% confidence interval: 1.15, 1.43). Low skeletal muscle attenuation (indicating muscle quality) was associated with poor overall survival (hazards ratio: 1.32; 95% confidence interval: 1.05, 1.66). Recurrence-free survival was similar in patients with low and normal/high skeletal muscle attenuation (hazards ratio: 1.12, 95% confidence interval: 0.89, 1.40).

Conclusion: Both low skeletal muscle mass and poor muscle quality are associated with poor long-term survival. Low skeletal muscle index, but not low skeletal muscle attenuation, are associated with poor recurrence-free survival.
