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.

Objective: The aim of this original study was to investigate general surgeons' perceptions on the role of dual surgeon operating for high-risk, elective complex surgical procedures.

Material and methods: A 21-part cross-sectional online survey was self-completed by 85 general surgeons across hospitals in the UK. The survey assessed the perception of dual surgeon operating on patient morbidity and mortality, surgeons' burnout rates, complaints, patient waiting times and overall trainee experience. Statistical analysis was performed using R version 3.6.1.

Results: Overall 78.8% believed that dual surgeon operating could help to overcome these human factors. Sub-analysis includes improve surgeon fatigue (89.4%), improve confidence (83.5%), improve decision-making (76.5%), minimise technical error (69.4%), improve communication, team work and leadership skills (65.9%). 65.9% believed it would reduce surgeons' burnout. There was a statistically significant relationship between the participants believing it would reduce surgeons' burnout and those who felt it would reduce complaints, Chi-squared(4) = [30.8], p = [0.00000342]. A statistically significant relationship was noted between participants believing it would reduce surgeons' burnout and those who felt it would reduce patient mortality/morbidity, Chi-squared(4) = [19.9], p = [0.000517].

Conclusion: The survey has highlighted positive surgeons' perceptions regarding dual surgeon operating.

Objective: Cervical elastography has been used in pregnant women to diagnose preterm births. However, there is a variability in the measured elasticity parameters and imaging mode used. We evaluated the precision of cervical elastography in identifying preterm births.

Methods: Extensive and methodical searches were made in the databases such as Scopus, Embase, Cochrane Library, PubMed Central, Medline, ScienceDirect, and Google Scholar from the inception until November 2022, for studies that report diagnostic accuracy of cervical elastography for preterm deliveries in antenatal women.

Results: The pooled sensitivity and specificity value of cervical elastography for preterm deliveries were 82% (95%CI: 73%-89%) and 77% (95%CI: 64%-86%), respectively with area under curve (AUC) of 0.87 (95%CI: 0.72-0.95). The diagnostic odds ratio (DOR) was 15 (95%CI: 8-28), positive likelihood ratio (LRP) was 3.5 (95%CI: 2.3-5.5) and negative likelihood ratio LRN was 0.23 (0.16-0.34). Pooled sensitivity and specificity of shear wave elastography was 88% and 71%, respectively. Pooled sensitivity and specificity of strain elastography was 80% and 79%, respectively. Heterogeneity was significant, as indicated by chi-square test and an I² statistic of over 75.

Conclusions: Cervical elastography can be used for predicting preterm deliveries with moderate to high level of accuracy.
