Abstract:

Skin cancers represent a major health concern, and there is a need for more effective treatment approaches, among which immune checkpoint inhibitors have become a particularly important recent development. This study aimed to explore the efficacy and tolerability of immune checkpoint inhibitors, intratumoral immunotherapies, targeted agents, and their combinations in advanced cutaneous malignancies. A Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)-conform review of PubMed (2012-2024) identified 26 studies, including randomized trials, observational cohorts, network meta-analyses, and systematic reviews, evaluating checkpoint inhibitors, anti-PD-1/PD-L1and anti-CTLA-4. Outcomes included progression-free survival (PFS), objective response rate (ORR), overall survival (OS), biomarkers, and treatment-related adverse events. This meta-analysis of 26 studies (2012-2024) evaluated treatments for cutaneous malignancies, including melanoma, basal cell carcinoma (BCC), cutaneous squamous cell carcinoma (cSCC), and Merkel cell carcinoma (MCC), covering systemic immunotherapies (PD-1, CTLA-4), combination checkpoint inhibitors, and novel approaches like IL-12 electroporation. Melanoma: PD-1 therapies showed durable benefits; ipilimumab retreatment yielded 42% two-year survival. MCC: Avelumab achieved a median OS of 12.9 months. cSCC: Nivolumab PFS 8.2 months; cemiplimab 12-month PFS >53%. Targeted therapy: BRAF/MEK inhibitors reached OS ~33 months. Emerging strategies: TIL-based and neoadjuvant immunotherapy showed high pathological and durable responses. Overall, combination therapies consistently outperformed monotherapies in survival and response. Adverse events were common, especially with combination therapy, with severe immune-related toxicities reported in 30-59% of cases, while monotherapies were generally safer. Overall, immunotherapy offers substantial, often long-lasting benefits, though careful patient selection and monitoring are essential to balance efficacy and toxicity. Combination immunotherapies and targeted regimens are more effective for advanced melanoma, although they have increased toxicity.

Abstract:

OBJECTIVE: This study aimed to evaluate the association between body mass index (BMI) and short-term outcomes following primary unilateral total knee arthroplasty (TKA), including functional improvement, perioperative variables, and postoperative complications.

METHODOLOGY: A retrospective case-control study was conducted at a tertiary orthopedic center on 525 consecutive patients who underwent primary unilateral TKA for osteoarthritis between January 2019 and December 2023. Patients were classified according to World Health Organization (WHO) BMI criteria: normal (18.5-24.9 kg/m2), overweight (25.0-29.9 kg/m2), and obese (>=30.0 kg/m2). Collected data included demographics, American Society of Anesthesiologists (ASA) grade, Charlson Comorbidity Index (CCI), glycated hemoglobin (HbA1c), operative time, length of hospital stay, change in Knee Society Score (DELTAKSS) at 12 months, patient-reported outcome measures, satisfaction, revision surgery, and postoperative complications. Between-group comparisons were performed using one-way analysis of variance (ANOVA) for continuous variables and chi-square or Fisher's exact tests for categorical variables, with significance set at p < 0.05.

RESULTS: Baseline characteristics were comparable across BMI groups, except for higher ASA scores and HbA1c levels in obese patients (p < 0.05). Obese patients had significantly longer operative times (95.9 +/- 16.8 minutes) and hospital stays (4.8 +/- 1.2 days) than normal-weight patients (83.6 +/- 14.1 minutes; 3.9 +/- 1.0 days, p < 0.01). All BMI groups demonstrated significant improvement in DELTAKSS at 12 months, although the gain was lowest in obese patients (34.7 +/- 10.5 vs. 41.2 +/- 9.6; p = 0.012). Overall complications were highest in the obese group with 16 patients (9.1%), followed by nine patients (5.1%) in the overweight group and seven patients (4.0%) in the normal-weight group, with wound-related issues being the most common. Revision surgery occurred in one (0.6%) obese patient, and no mortality was reported.

CONCLUSION: Higher BMI was associated with longer operative times, prolonged hospital stays, increased wound complications, and slightly reduced functional improvement and satisfaction at 12 months after primary TKA. These findings highlight the importance of optimizing metabolic status before surgery and emphasize the need for individualized perioperative risk assessment in patients undergoing knee arthroplasty.

Abstract:

Eagle's syndrome describes the elongation of the styloid process. The condition has been recognised for over 90 years and causes a wide range of symptoms depending on the level of compression. Compression of the internal carotid artery by the styloid process is referred to in the literature as 'stylocarotid syndrome' or 'vascular Eagle's syndrome' (VES), presenting most commonly as arterial dissection and cerebrovascular events. We present the case of a 53-year-old patient who presented with multiple cerebrovascular events over a six-month period. Computed tomography angiography (CTA) suggested VES; however, magnetic resonance imaging (MRI) of the neck revealed no arterial wall abnormalities, including dissection. Despite the escalation of medical therapy, the patient continued to experience multiple transient ischaemic attacks. Following multidisciplinary team discussion and exclusion of other sources of emboli, a transcervical styloidectomy was performed freeing compression of the carotid artery, resulting in the complete resolution of symptoms. VES should be considered in patients with recurrent or unexplained cerebrovascular or cervical neurogenic symptoms even in the absence of arterial injury. We recommend early styloidectomy when there is a strong clinical suspicion of VES to achieve definitive symptom resolution.

Abstract:

Introduction: Understanding factors influencing individual survival outcomes following surgical resection of locally advanced (LARC) rectal cancer remains challenging. Novel biomarkers could show emerging promise in this setting. This study aimed to systematically review the literature on immune prognostic factors in LARC.

Methods: The review protocol was preregistered on the PROSPERO database (CRD42023460541). Included studies were required to report overall survival and at least one immune prognostic factor for at least ten patients with LARC. Final searches of MEDLINE, EMBASE and Central were concluded on 8th September 2023. The risk of bias was assessed using the QUIPS tool.

Results: 22 retrospective cohort studies involving 2,622 LARC patients were included in the review. We did not find any published data on immune prognostic factors in locally recurrent rectal cancer. Due to inconsistency of immune prognostic factor definitions and measurement methods, meta-analysis would not be meaningful. Instead, the results are presented descriptively. Risk of bias was concentrated in the participation, attrition, and confounding domains. Greater cytotoxic cell infiltration was associated with improved overall survival. There was inconsistent evidence of an association of PD-L1 expression and survival. M2 macrophage infiltration and homozygous germline FPR1 loss-of-function were associated with worse survival.

Discussion: These findings support a role for both innate and acquired immune systems in mediating outcomes following surgery for LARC and suggest that further work into immunomodulation may show promise in improving LARC treatment.

Abstract:

Colonoscopy is the gold standard in the prevention of colorectal cancer, but the miss rates of adenoma are high, which restricts its efficacy. To improve lesion recognition, artificial intelligence (AI), especially computer-aided detection (CADe) systems, has been introduced. The aim of this systematic review was to compare AI-assisted colonoscopy in terms of its ability to improve adenoma detection rate (ADR) and polyp detection rate (PDR). An extensive search was performed on PubMed, Embase, and Cochrane Library from 2015 to 2025. There were 17 randomized controlled trials (RCTs) comparing the use of AI-assisted colonoscopy with normal colonoscopy. The methodological quality measure of the included RCTs was Cochrane Risk of Bias 2.0 (RoB 2.0), which subdivided the studies based on low risk, some concerns, or high risk of bias based on whether they were biased in this or that domain. The robVis tool was used to produce the visual summaries. AI-aided colonoscopy effectively enhanced both adenoma detection rate (ADR) and polyp detection rate (PDR) in all of the included studies over conventional colonoscopy. In adenoma detection, accuracy was more than 85%, and in polyp detection, more than 90%. The advantage was also found especially in the detection of small and flat adenomas, which are very often missed in routine practice. The use of AI in colonoscopy is strongly associated with an increase in the detection rate of adenoma and polyps, minimizing the risk of underdiagnosis. The results highlight the clinical promise of AI in the form of a decision-support tool across gastroenterologists and suggest that AI can be applied to enhance the outcomes of preventive and screening colorectal cancer. Future research should be cost-efficient and practical, and combined with some clinical activities.

Abstract:

Introduction: Most frequent injuries of the Upper limb are a distal radius fracture (DRF). If they aren't handled well, they might cause problems for a long time. There are several techniques to treat this issue, but volar locking plate fixation has become increasingly prevalent since it may restore anatomical alignment, provide stable fixation, and allow for early movement. This study aimed to evaluate the functional and radiological results of distal end radius fractures treated with volar locking plate
fixation.

Materials and Methods: In this prospective analytical investigation, 60 patients with DRFs, ranging in age from 18 to 80 years, were enrolled. Patients were treated with open reduction and internal fixation using volar locking devices. Functional results are evaluated using the Gartland and Werley Demerit Point System and goniometry. Radial length, radial inclination, palmar tilt, and articular step-off were employed to quantify radiological outcomes. Follow-up evaluations were conducted at 2, 4, and 6 weeks, in addition to 6 months. We used the Statistical Package for the Social Sciences version 20 to analyze the data and discovered that P < 0.05 was significant.

Results: Patients exhibited substantial improvement in wrist function across all planes of motion, with plantar flexion rising from 31.6degree at 2 weeks to 67.8degree at 6 months, and dorsiflexion from 31.7degree to 66.4degree. Supination and pronation also became a lot better, becoming close to normal levels after 6 months. The radiographic restoration was good, with a mean radial length of 8.8 mm, an inclination of 17.6degree, and a palmar tilt of 8.9degree. There were very few complications (6.7% arthritis, 6.7% malunion).

Discussion: Our results support previous research showing volar plating offers robust fixation, restores anatomical alignment, and facilitates early mobility. Correlation study revealed that palmar tilt and articular congruity substantially impacted functional recovery, emphasizing the need of meticulous surgical reduction.

Conclusion: Volar locking plate fixation is an effective treatment for DRFs, characterized by low complication rates and excellent functional and radiological outcomes.

Abstract:

Background
Never-events represent serious and preventable patient safety incidents within surgical practice, despite increasing national and international efforts to reduce them. Persistent concerns regarding wrong site surgery, retained surgical items, and incorrect implants highlight the need to understand contributory human factors and system-level weaknesses.

Methods
A systematic search of PubMed/Medline, Google Scholar, and the Cochrane Library was conducted. Evidence published between 2014 and 2024 was screened according to predefined eligibility criteria to identify contemporary data relating to surgical never-events. Studies were assessed using standardised selection methods and relevant findings were extracted and synthesised.

Results
Thirty-seven studies met inclusion criteria. Across international literature, recurring contributory factors included communication breakdowns, reduced situational awareness, fatigue, inadequate staffing, inconsistent team composition, and increasing surgical caseloads. Despite advances in safety practices, these factors continued to contribute to adverse surgical outcomes.

Conclusion
Never-events remain a persistent challenge in surgical care. Strengthening safety management systems, improving awareness of human factors, and prioritising non-technical skills training may help reduce the risk of these events. Ongoing evaluation of interventions and further UK-based research are required to support improvement in patient safety outcomes.

Data availability
All data generated or analysed in this study are derived from published articles and are included within this manuscript and its supplementary materials.

Abstract:

Background and objective We aimed to determine whether audit, feedback, and education improves surgical performance after transurethral resection of bladder tumour surgery for non-muscle-invasive bladder cancer and as a secondary aim if it reduced recurrence rates. Methods This cluster randomised controlled trial compared audit and feedback plus peer comparison and education, with audit alone for four coprimary outcomes: (1) Single-instillation chemotherapy, (2) detrusor muscle sampling, (3) documentation of tumour features, and (4) resection completeness. Early recurrence was a secondary outcome. Key findings and limitations A total of 100 sites were randomised to intervention and 101 to control. In total, 14 915 patients were included. Intervention sites significantly improved documentation of tumour features (adjusted mean difference [95% confidence interval {CI}]: 6.0 [1.8, 10], p = 0.005) and of resection completeness (adjusted mean difference [95% CI]: 5.5 [1.5, 9.5], p = 0.007). There was no statistically significant difference in chemotherapy use (adjusted mean difference [95% CI]: 0.3 [-4.7, 5.3], p = 0.9) or detrusor muscle sampling (adjusted mean difference [95% CI]: 2.6 [-1.3, 6.4], p = 0.2). There was no statistically significant difference in early recurrence rate between arms (adjusted odds ratio [95% CI]: 1.02 [0.8, 1.4], p = 0.9); however, in the control arm, the early recurrence rate reduced compared with baseline (adjusted odds ratio [95% CI]: 0.7 [0.6, 0.9]). Conclusions and clinical implications Audit and feedback with education improved the documentation of important surgical findings that influence clinical management, but not the performance of detrusor muscle sampling, adjuvant chemotherapy use, or early recurrence rates. Improvements observed in the control arm may explain a lack of effect of the intervention in some outcomes.

Abstract:

Introduction Quadriceps and patellar tendon ruptures are uncommon but disabling injuries that require surgical repair. Changes in physical activity patterns during and after the COVID-19 pandemic may have influenced their occurrence. This study compares the incidence, demographics, and seasonal distribution of these injuries before and after the pandemic within a single UK NHS trust. Methods A retrospective review was performed of all patients undergoing primary repair of quadriceps or patellar tendon ruptures at the Shrewsbury and Telford NHS Trust from January 2014 to December 2024. The pre-COVID period (2014-2019) was compared with the post-COVID period (2021-2024), with 2020 excluded due to major service disruption and atypical clinical pathways during the first pandemic year. Annual incidence rates were calculated as cases per 100,000 population, using year-specific catchment population estimates from the Office for National Statistics (ONS). Demographic variables, injury characteristics, and seasonal patterns were extracted from electronic records. Between-period comparisons used the Mann-Whitney U test. No adjustment for age, BMI, or comorbidities was performed. Results A total of 203 patients were identified, including 95 pre-COVID and 108 post-COVID. The median age was 63 years (range 15-90), with a male-to-female ratio of 7.8:1. Injuries occurred most frequently in autumn (28%). The median annual incidence increased from 4.6 per 100,000 pre-COVID to 8.3 per 100,000 post-COVID (incidence rate ratio 1.8, p = 0.0073). The median number of cases per year rose from 16 to 27 between periods. Conclusion The incidence of surgically treated quadriceps and patellar tendon ruptures increased in the post-COVID period. Although the study does not adjust for potential confounders, the findings suggest an association between the post-pandemic era and higher injury rates. Further research with multivariable analysis is needed to clarify contributing factors.

Abstract:

BACKGROUND: The global administration of billions of COVID-19 vaccine doses has raised concerns about potential adverse effects, contributing to vaccine hesitancy. While transient mild discomfort is common after intramuscular vaccination, persistent and severe post-vaccination shoulder pain has led to recognition of Shoulder Injury Related to Vaccine Administration (SIRVA). SIRVA is characterised by shoulder pain and restricted range of motion typically occurring within 48 hours of inoculation, thought to result from inadvertent vaccine delivery into the subdeltoid bursa. In addition to its clinical definition, SIRVA is also viewed as a medicolegal construct, particularly in the context of vaccine injury compensation frameworks. This study aimed to describe our experience with patients presenting with SIRVA-like symptoms following COVID-19 vaccination, compare these findings with published literature, and assess clinical outcomes.

METHODS: A retrospective study was conducted at a major trauma centre. All patients presenting to the orthopaedics department with atypical shoulder symptoms following COVID-19 vaccination between January and December 2021, with at least six months of follow-up, were reviewed. Only patients meeting the Health Resources and Services Administration (HRSA) Vaccine Injury Table diagnostic criteria for SIRVA were included. Data on demographics, vaccine type, clinical findings, investigations, treatment, and outcomes were collected.

RESULTS: Of the 31 patients presenting with post-vaccination shoulder symptoms, 16 (52%) met the HRSA criteria for SIRVA. The mean age was 54 years, and 63% were female. All patients presented with shoulder pain and reduced range of motion. The mean follow-up duration was 12 months. Most patients (94%) were treated non-operatively with analgesia, nonsteroidal anti-inflammatory drugs (NSAIDs), and physiotherapy. At one-year follow-up, 44% achieved complete or near-complete recovery, while 31% (n =5) reported no improvement and required specialist referral.

CONCLUSION: SIRVA is a rare complication following COVID-19 vaccination and is best considered a medicolegal term rather than a definitive diagnosis. Strict adherence to diagnostic criteria is essential, as overdiagnosis may occur among patients with coincidental post-vaccination shoulder pain. While most cases resolve with conservative management, a subset may experience persistent symptoms. Evidence suggests that SIRVA is more likely related to improper injection technique rather than the vaccine itself.
