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.

Background and aims: The complete pathological response (pCR) following neoadjuvant chemotherapy (NAC) in breast cancer is essential for the accurate prediction of prognosis. We aimed to evaluate the efficacy of the presence and type of peritumoral edema detected by magnetic resonance imaging (MRI) in predicting pCR to NAC in breast cancer patients.

Methods and results: One hundred five patients with the diagnosis of invasive carcinoma were evaluated by MRI before NAC. Edema was evaluated in fat-suppressed T2-weighted images. The patients were categorized into three groups: patients with no peritumoral edema, patients with peritumoral edema, and patients demonstrating subcutaneous edema. The cases were categorized as being pCR and non-pCR. Molecular subtypes, lymphovascular invasion (LVI), tumor size, and apparent diffusion coefficient (ADC) were evaluated. A positive relationship was found between the presence of edema and tumor size. Subcutaneous edema was found to be statistically higher in non-pCR patients. While the number of pCR patients with subcutaneous edema was 17 (30.4%), the number of non-pCR patients with subcutaneous edema was 26 (53.1%) (p  =  0.018). LVI was found to be statistically higher in patients with edema. The number of edema-negative and LVI (+) patients was 4 (15.4%), while the number of edema-positive and LVI (+) patients was 28 (35.4%) (p = 0.042). Intratumoral and peritumoral ADC values were significantly higher in tumors with edema.

Conclusion: The presence of subcutaneous edema and LVI may be utilized for the prediction of pCR outcomes in breast cancer patients scheduled for NAC treatment.

Background and aims: Developing and implementing an educational and training programmes for improving hand hygiene compliance of the nursing personnel might help in increasing their knowledge, promoting positive attitude and follow adequate practice measures.

Material and methods: Systematic search was done in PubMed, SCOPUS, CENTRAL, EMBASE, ScienceDirect, Clinicaltrials.gov and Google Scholar databases for articles published between 1964 and December 2022. Meta-analysis was carried out using a random-effects model, and the results were reported as pooled risk ratio (RR) with 95% confidence intervals (CIs), pooled standardised mean differences (SMD) or risk ratios (RR).

Results: Eight studies were included in the analysis. Most studies had higher risk of bias. Nurses receiving educational and training programmes had significantly higher compliance to hand hygiene practices (pooled RR of 1.69 [95% CI: 1.23-2.31; I²  =  99.1%], p  =  0.001). The pooled analysis based on studies reporting the compliance to hand hygiene as continuous outcome has reported the pooled SMD as 1.28 with 95% CI: 0.62 to 1.95 and I²  =  74.5%. There were no single-study effects with respect to this outcome, since the sensitivity analysis showed no difference in either direction or strength of effect estimate.

Conclusion: Educational and training programmes are effective in improving the hand hygiene compliance amongst the nursing professionals.

Objective: This review aimed to examine if the platelet-lymphocyte ratio and lymphocyte-monocyte ratio can be useful in determining disease activity in patients with inflammatory bowel disease.

Methods: PubMed, CENTRAL, Scopus, Embase, and Web of Science were searched for studies published up to 9 January 2023. Platelet-lymphocyte ratio and lymphocyte-monocyte ratio values from active and remission inflammatory bowel disease cases were compared to generate a mean difference (MD).

Results: Nine studies were included. Meta-analysis showed that inflammatory bowel disease patients with active disease had significantly higher values of platelet-lymphocyte ratio as compared to those in remission (MD: 63.46 95% CI: 35.74, 91.17, I²= 89%). The values of platelet-lymphocyte ratio were significantly higher in both active ulcerative colitis and Crohn's disease patients. Meta-analysis also showed that lymphocyte-monocyte ratio values were significantly lower in active inflammatory bowel disease patients as compared to those under remission (MD: -1.28 95% CI: -1.42, -1.14, I²= 4%). Lymphocyte-monocyte ratio values were significantly lower in both ulcerative colitis and Crohn's disease patients with active disease.

Conclusion: Platelet-lymphocyte ratio and lymphocyte-monocyte ratio can be useful blood-based markers in differentiating active disease in inflammatory bowel disease patients. Active cases of ulcerative colitis and Crohn's disease have high platelet-lymphocyte ratio and low lymphocyte-monocyte ratio as compared to those in remission. Further studies with a larger sample size are needed to strengthen conclusions.
