Abstract:

Creatine monohydrate (Cr) is a widely used supplement in the sports and fitness industry, with its popularity continuing to rise. It is well known for its ability to maintain high-energy phosphate levels during intense physical activity, thereby enhancing performance. Documented benefits of creatine supplementation include enhanced muscular development, neuroprotective effects in certain neurodegenerative conditions, and potential cardiovascular advantages. Nonetheless, a growing body of reports has raised concerns regarding possible adverse vascular effects, particularly an increased risk of thrombosis. This case underscores the potential thrombotic risks associated with creatine use and highlights the need to re-evaluate its safety profile. In addition, we provide an updated review of the literature regarding this potentially serious adverse effect.

Abstract:

Cardiotocography (CTG) is a common investigative modality in obstetrics to evaluate the fetal condition. Advancements in digital technology has enabled the innovation of CTG monitoring for usage in the home setting. This review aims to comprehensively examine the current evidence on the effectiveness and applicability of home antenatal CTG monitoring. MEDLINE, EMBASE, Cochrane, Web of Science, and PubMed databases were searched from inception to June 2025. Primary studies examining home antenatal CTG were included. For randomised controlled trials (RCTs), the joint primary outcomes were perinatal mortality and emergency caesarean section. For observational studies, the feasibility, diagnostic accuracy, qualitative and economic burden of home CTG were evaluated. RCTs were eligible for meta-analysis using risk ratio or mean difference, with 95% confidence intervals. Included observational studies were narratively described due to significant methodological heterogeneity. 39 studies (28 observational, seven RCTs and four qualitative studies), comprising of 7240 participants were included. Home antenatal CTG monitoring was non-inferior to conventional care across all meta-analysed maternal, perinatal and healthcare usage outcomes. GRADE assessments were low/very low quality of evidence. Home CTG monitoring was feasible in several settings and remote interpretation was graded as moderate to excellent. Transmission failures were frequently low but commonly occurred due to infrastructure and/or equipment errors. Remote CTG monitoring demonstrated comparative capabilities to conventional CTG with respect to coincidence and beat-to-beat variability. Overall acceptability ratings were high for patient and providers. Often implementation costs were high but accrued back by non-fixed savings when compared against routine care. High-quality studies were underrepresented, particularly when assessing service-led and safety outcomes. Home antenatal CTG monitoring demonstrates noninferiority to conventional care across several outcomes, representing a promising avenue for antenatal management However, current evidence is of low quality and additional high-quality evidence with sufficient methodological detail and standardised outcome assessment is required prior to making definitive recommendations.

Abstract:

The diagnosis and management of pacemaker-related infective endocarditis present significant challenges, with limited available data. Accurately attributing a systemic infection to pacemaker endocarditis can be difficult, particularly in identifying vegetations and obtaining positive blood cultures from patients who have undergone non-specific antibiotic therapy. Moreover, such infections may manifest long after pacemaker implantation. Herein, we present a male patient in his 70s, with a history of pacemaker placement, who was admitted with a three-month history of fever and chills, having already completed two courses of empirical antibiotics prior to admission. Upon hospital admission, he was treated for an infection of unknown origin with intravenous antibiotics. Initial laboratory evaluations indicated leucocytosis and elevated C-reactive protein levels; however, blood cultures and infectious serologies returned normal results. A CT scan of the abdomen and pelvis was deemed unremarkable, and transthoracic echocardiography (TTE) also yielded normal findings. The empirical antibiotic regimen was discontinued, leading to three sets of blood cultures being subsequently positive for coagulase-negative Staphylococcus epidermidis. A transoesophageal echocardiography (TOE) was performed, revealing vegetation on the pacemaker lead. The patient received a triple antibiotic therapy and underwent device removal; subsequent blood cultures were negative following a four-week antibiotic course. A new pacemaker was implanted, and the patient has since remained asymptomatic. This case illustrates that coagulase-negative Staphylococcus epidermidis can infect pacemaker leads even long after installation, potentially leading to an indolent course of infective endocarditis that is difficult to diagnose and manage. Consequently, clinicians should maintain a high index of suspicion for pacemaker infective endocarditis in patients presenting with prolonged fever.

Abstract:

Metabolic syndrome (MetS) is a cluster of cardiometabolic abnormalities, including abdominal obesity, insulin resistance, dyslipidemia, and elevated blood pressure, that increases the risk of type 2 diabetes and cardiovascular disease (CVD). Autonomic imbalance, characterized by increased sympathetic activity and reduced parasympathetic tone, is proposed to play an important role in the development of hypertension and adverse cardiovascular outcomes in individuals with MetS. This systematic review evaluates the association between autonomic nervous system (ANS) dysregulation and MetS. A systematic search was conducted in PubMed, Embase, Scopus, and Cochrane Library for studies published from January 2015 to September 2025. Eligible studies included human research that examined measures of autonomic function such as heart rate variability (HRV), baroreflex sensitivity, muscle sympathetic nerve activity, and plasma catecholamine levels at rest in individuals with MetS. Observational and interventional studies were included. Data were extracted and synthesized narratively. A total of 16 studies met the inclusion criteria. Most included studies reported reduced HRV, impaired baroreflex sensitivity, increased resting sympathetic nerve activity, and elevated plasma catecholamines in participants with MetS, suggesting a consistent association between ANS dysregulation and blood pressure elevation. However, causality could not be established due to the predominantly observational study designs. Current evidence indicates a significant association between autonomic dysfunction and MetS, particularly in relation to hypertension and increased cardiovascular risk. ANS biomarkers may support refined cardiometabolic risk stratification, although further prospective and mechanistic studies are needed to clarify causal pathways.

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:

INTRODUCTION: Acute cholecystitis is typically managed with laparoscopic cholecystectomy, though inflammation and distorted anatomy can increase operative difficulty. Robotic cholecystectomy may offer technical advantages through improved visualisation and instrument dexterity, yet current evidence is limited, heterogeneous, and entirely observational, with no randomized trials comparing the two approaches in the emergency setting. This systematic review and meta-analysis synthesises existing comparative data to determine whether robotic assistance confers meaningful operative or postoperative benefits over standard laparoscopy in acute cholecystitis.

MATERIALS AND METHODS: A PRISMA-compliant systematic review and meta-analysis was performed. Comprehensive searches of major databases (2015-2025) identified comparative studies of robotic versus laparoscopic cholecystectomy for acute/emergency cholecystitis in adults. Eligible studies reported at least one perioperative or postoperative outcome; elective, paediatric, single-incision, and non-comparative designs were excluded. Outcomes included operative time, conversion, intra-operative complications, bile duct injury, length of stay, readmission, reoperation, and mortality. Risk of bias was assessed using ROBINS-I. Meta-analyses were conducted in RevMan using random-effects models, with heterogeneity assessed by I2 and standard continuity corrections applied for zero-event studies.

RESULTS: Seven observational studies comprising 143,717 patients met the inclusion criteria. Operative time and length of stay could not be meta-analysed due to inconsistent reporting and were therefore summarised narratively, with both outcomes appearing broadly comparable between robotic and laparoscopic groups. Meta-analysis demonstrated a significantly lower risk of conversion to open surgery with robotic cholecystectomy (RR 0.61, 95% CI 0.50-0.75; I2 = 44%). No significant differences were observed between robotic and laparoscopic approaches for intra-operative complications (RR 0.72, 95% CI 0.38-1.36; I2 = 40%), bile duct injury (RR 0.97, 95% CI 0.77-1.21; I2 = 0%), overall postoperative complications (RR 1.10, 95% CI 0.80-1.52; I2 = 95%), 30-day readmission (RR 0.88, 95% CI 0.50-1.54; I2 = 18%), reintervention or return to theatre (RR 0.33, 95% CI 0.04-2.48; I2 = 78%), or 30-day mortality (OR 1.28, 95% CI 0.86-1.90; I2 = 0%). Event rates for bile duct injury, major complications, reintervention, and mortality were uniformly low across all cohorts, limiting the precision of pooled estimates. Risk-of-bias assessment using ROBINS-I indicated a moderate to serious overall risk of bias in six of the seven studies, primarily due to residual confounding, non-random treatment allocation, and incomplete reporting of disease severity and operative complexity.

CONCLUSION: Robotic cholecystectomy is a safe and feasible alternative to laparoscopy for acute cholecystitis, demonstrating a consistent reduction in conversion to open surgery and comparable intra-operative and postoperative safety outcomes. However, as current evidence is limited to heterogeneous observational studies with incomplete clinical detail, robust prospective research-with detailed severity grading, surgeon-experience assessment, workflow evaluation, and cost-effectiveness analysis-is needed to more clearly define its role in emergency biliary surgery.

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:

Objective: Referrals to the menopause clinic for testosterone and low libido have steadily increased. Locally, we have written prescribing information for primary care to follow, after testosterone initiation in the menopause clinic. This prescribing information adheres to British Menopause Society (BMS) guidelines but has only recently been introduced. The objective of this audit was to determine if the BMS guidelines are currently being followed. Method(s): Retrospective case note review of a selection referrals to the Menopause by two speciality registrars training in Menopause. The electronic patient records were reviewed using pre-determined criteria and recorded on the same secure spreadsheet. Result(s): A total of 245 patient notes were reviewed, of these patients 35 had been specifically referred to request testosterone. 33 of these 35 patients were able to fully discuss testosterone in the menopause clinic. All patients were already taking Hormone replacement therapy (HRT). 32 patients reported that their libido had changed around the time of the menopause. Only 15 patients were already taking vaginal estrogen. 6 patients did not have a baseline testosterone level prior to commencement of testosterone. 24 patients were subsequently started on testosterone. Only 10 patients had reported testosterone levels at 3 months. 4 were referred for psychosexual counselling. Conclusion(s): This audit demonstrated how locally we would benefit from keeping a specific log of patients on testosterone. This is to ensure that patients have their baseline testosterone levels and subsequent monitoring, to make sure testosterone levels are being kept in the physiological range. Our audit showed only a small proportion of patients were already using vaginal estrogen, Vaginal dryness can be a contributing factor to low libido. By increasing uptake in vaginal estrogen this may help some patients prior to their referral or potentially reduce the need for referral. In addition, psychosexual counselling was provided for some of these patients and identified further contributing factors towards low libido, highlighting the importance of a holistic approach to the management of low libido. In those where testosterone was not commenced, this was mostly due to low estrogen levels therefore HRT regimes were altered to optimise absorption prior to considering testosterone.
