Abstract:

INTRODUCTION: Recent studies have suggested that ambulatory management is feasible for acute uncomplicated diverticulitis (AUD); however, there is still no consensus regarding the most appropriate management settings. This study presents a multi-centre experience of managing patients presenting with AUD, specifically focusing on clinical outcomes and comparing ambulatory treatment with in-patient management.

METHODS: A retrospective multi-centre study was conducted across four hospitals in the UK and included all adult patients with computed tomography (CT) confirmed (Hinchey grade 1a) acute diverticulitis over a
12-month period (January – December 2022). Patient medical records were followed up for 1-year post-index episode, and outcomes were compared between those treated through the ambulatory pathway versus inpatient treatment using 1:1 propensity score matching (PSM). All statistical analysis was performed using the R Foundation for Statistical Computing, version 4.4.

RESULTS: A total of 348 patients with Hinchey 1a acute diverticulitis were included (260 in-patients; 88 ambulatory pathway), of which nearly a third (31.3%) had a recurrent disease. Inpatient management was dominant (74.7%), with a median of 3 days of hospital stay. PSM resulted in 172 patients equally divided between the two care settings. Ambulatory management was associated with a lower readmission rate (P = 0.02 before PSM, P = 0.08 after PSM), comparable surgical (P = 0.57 before PSM, 0% in both groups after PSM) and radiological interventions (P = 0.99 before and after PSM) within one year. In both matched and non-matched groups, a strong association between readmissions and inpatient management was noted in univariate analysis (P = 0.03 before PSM, P = 0.04 after PSM) and multivariate analysis (P = 0.02 before PSM, P = 0.03 after PSM).

CONCLUSION: Our study supports the safety and efficacy of managing patients with AUD through a well-designed ambulatory care pathway. In particular, hospital re-admission rates are lower and other outcomes are non-inferior to in-patient treatment. This has implications for substantial cost-savings and better utilisation of limited healthcare resources.

Abstract:

INTRODUCTION: Direct laryngoscopy and biopsy is the gold standard for obtaining a tissue diagnosis in patients with suspected laryngeal cancer. In patients with advanced disease or other medical comorbidities, this may come with significant anaesthetic risks, including tracheostomy. Ultrasonography-guided biopsy has been widely used in the diagnosis of malignancy involving cervical lymph nodes but it is not commonly employed in the diagnosis of laryngeal tumours. A systematic review was undertaken to assess the literature looking at whether ultrasonography-guided transcutaneous fine needle aspiration cytology (FNAC) is an adequate method in diagnosing laryngeal malignancy.

METHODS: Two independent researchers conducted a systematic review of the literature using the MEDLINE and Cochrane Library databases in accordance with the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines.

RESULTS: A total of 568 studies were identified from the search, of which 3 met the inclusion criteria, resulting in 162 patient episodes. The pooled accuracy of transcutaneous FNAC in acquiring a sample adequate for histological diagnosis was 74.9%. Data on complications were limited, with a few cases of mild haemoptysis being recorded.

CONCLUSIONS: Transcutaneous FNAC can be considered a safe and quick method for establishing a histological diagnosis of laryngeal lesions, particularly in patients who may be severely comorbid, and it could therefore could reduce the risks of general anaesthesia and tracheostomy prior to commencing definitive treatment.

Abstract:

The Parkinson's Families Project is a UK-wide study aimed at identifying genetic variation associated with familial and early-onset Parkinson's disease (PD). We recruited individuals with a clinical diagnosis of PD and age at motor symptom onset <=45 years and/or a family history of PD in up to third-degree relatives. Where possible, we also recruited affected and unaffected relatives. We analysed DNA samples with a combination of single nucleotide polymorphism (SNP) array genotyping, multiplex ligation-dependent probe amplification (MLPA), and whole-genome sequencing (WGS). We investigated the association between identified pathogenic mutations and demographic and clinical factors such as age at motor symptom onset, family history, motor symptoms (MDS-UPDRS) and cognitive performance (MoCA). We performed baseline genetic analysis in 718 families, of which 205 had sporadic early-onset PD (sEOPD), 113 had familial early-onset PD (fEOPD), and 400 had late-onset familial PD (fLOPD). 69 (9.6%) of these families carried pathogenic variants in known monogenic PD-related genes. The rate of a molecular diagnosis increased to 28.1% in PD with motor onset <=35 years. We identified pathogenic variants in LRRK2 in 4.2% of families, and biallelic pathogenic variants in PRKN in 3.6% of families. We also identified two families with SNCA duplications and three families with a pathogenic repeat expansion in ATXN2, as well as single families with pathogenic variants in VCP, PINK1, PNPLA6, PLA2G6, SPG7, GCH1, and RAB32. An additional 73 (10.2%) families were carriers of at least one pathogenic or risk GBA1 variant. Most early-onset and familial PD cases do not have a known genetic cause, indicating that there are likely to be further monogenic causes for PD.

Abstract:

Objective: Assessment of gastrointestinal and autonomic symptoms in patients with systemic sclerosis, and possible associations with gastric emptying rate. Method(s): Participant and patient disease-related characteristics were collected. Gastrointestinal and autonomic symptoms were assessed by the UCLA-SCTC GIT 2.0 and COMPASS-31 questionnaires, respectively. Potentially confounding gastrointestinal medications were discontinued where possible. Gastric emptying was assessed using a non-radioactive <sup>13</sup>C sodium acetate isotope, end-expiratory breath samples collected at baseline and then serial timepoints up to 120 min. Result(s): In total, 49 participants were studied: 17 with systemic sclerosis with variable gastrointestinal involvement, and healthy matched (n = 17) and non-matched controls (n = 15), the last to control for the impact of age rather than disease on gastric emptying and autonomic function. The total mean (range) UCLA GIT 2.0 questionnaire for patients with systemic sclerosis was 0.63 (0.0-1.5) and for both healthy matched and non-matched controls was 0.04 (0.0-0.2), and was higher in patients with systemic sclerosis across all domains. The total mean (range) COMPASS-31 score for patients with systemic sclerosis patients was 32.2 (0.0-54.9) and for healthy matched- and non-matched controls: 7.45 (0.0-24.9) and 4.25 (0.0-2.1), respectively, again higher for patients with systemic sclerosis across all domains. No association was observed between patients' UCLA GIT 2.0 total score (s = -0.039, p = 0.38), total COMPASS 31 score (s = -0.108, p = 0.68), or COMPASS-31 GI domain (s = -0.051, p = 0.85) and gastric emptying rates. Conclusion(s): Gastrointestinal and autonomic symptoms are overrepresented in patients with systemic sclerosis but did not associate with gastric emptying rates.

Abstract:

Purpose: The aim of this study was to investigate how fear of reinjury to the Achilles tendon affects return to previous levels of physical activity and self-reported Achilles tendon Total Rupture Score (ATRS) outcomes.

Methods: Data were collected from a large cohort of patients treated for an acute Achilles tendon rupture at Sahlgrenska University Hospital Molndal between 2015 and 2020. The ATRS and additional questions concerning fear of reinjury, treatment modality, satisfaction of treatment and recovery were analyzed 1-6 years postinjury. Analysis was performed to determine the impact of fear of reinjury on patient-reported recovery and physical activity.

Results: Of a total of 856 eligible patients, 550 (64%) answered the self-reported questionnaire and participated in the follow-up. Of the participants, 425 (77%) were men and 125 (23%) were women. ATRS, recovery in percentage, satisfaction of treatment, recovery on a 5-point scale and physical activity level post- versus preinjury were significantly related to fear of reinjury (p < 0.001). Of the nonsurgically treated patients, 59% reported fear of reinjury compared to 48% of the surgically treated patients (p = 0.024) Patients that reported fear of reinjury had a 15-point lower median ATRS score than those who did not (p < 0.001).

Conclusion: More than half of patients who have suffered an Achilles tendon rupture are afraid of reinjuring their tendon. Patients who reported fear of reinjury exhibited a significantly lower ATRS score. This indicates the importance of addressing psychological aspects in the treatment after this injury.

Abstract:

We present a case of a 51-year-old woman diagnosed with light chain amyloidosis associated with monoclonal gammopathy of undetermined significance (MGUS). Initially, she presented with symptoms of heart failure, including palpitations, chest tightness, and shortness of breath, which were attributed to myocarditis based on cardiac magnetic resonance (CMR) imaging findings. However, her condition rapidly deteriorated, with recurrent admissions for worsening heart failure, cardiogenic shock, and stroke. A cardiac biopsy ultimately confirmed light chain amyloidosis, a rare complication of MGUS, which has a long-term risk of 0.8% in patients with light chain MGUS. Despite aggressive treatment, including chemotherapy and biventricular assist device implantation, her condition continued to decline, and she became ventilator-dependent and subsequently passed away. This case highlights the importance of considering amyloidosis in patients with MGUS and underscores the need for early diagnosis and intervention to prevent catastrophic outcomes.

Abstract:

BACKGROUND: Junior doctors often feel underprepared for their trauma and orthopaedics (T&O) rotation due to limited exposure during medical school and inadequate support. This project aimed to enhance junior doctors' preparedness and satisfaction during their T&O rotation by developing a comprehensive guidebook that addresses key orthopaedic knowledge and logistical challenges. METHODS: A quality improvement project (QIP) was conducted at Ysbyty Gwynedd Hospital. Initial surveys identified factors contributing to poor experiences during the trauma and orthopaedics rotation, including limited knowledge of orthopaedic emergencies and a lack of useful reference resources. A guidebook was developed and refined through multiple plan-do-study-act (PDSA) cycles. The guidebook covered topics such as orthopaedic emergencies, common injuries, referral pathways, and hospital logistics, presented in an accessible flowchart format. RESULTS: The primary objective of achieving 75% satisfaction among junior doctors was successfully met, with satisfaction increasing from four (40%) to eight (80%) doctors in the most recent survey. Secondary outcomes included a marked improvement in the understanding of quality improvement projects, rising from three (30%) to eight (80%) doctors. Orthopaedic knowledge also saw a significant enhancement, increasing from four (40%) to nine (90%) doctors. Confidence in handling night on-call duties improved dramatically, with all 10 doctors (100%) reporting increased confidence, compared to four (40%) doctors initially. Additionally, seven doctors (70%) expressed a greater interest in pursuing a career in orthopaedic surgery. CONCLUSION: The comprehensive guidebook significantly improved junior doctors' preparedness and satisfaction during their T&O rotation. While the guidebook is a valuable resource, ongoing mentorship and hands-on experience remain essential for long-term success. Replication of this project across other departments and hospitals is recommended to assess its broader applicability and impact.

Abstract:

PURPOSE: Men with high-risk prostate cancer (PCa) are treated with androgen deprivation therapy (ADT) and radiotherapy, but the disease reoccurs in 30% of patients. Biochemical recurrence of PCa after treatment is influenced by tumour hypoxia. Tumours with high levels of hypoxia are aggressive, resistant to treatment, and have increased metastatic capacity. Gene expression signatures derived from diagnostic biopsies can predict tumour hypoxia and radiosensitivity, but none are in routine clinical use, due to concerns about the applicability of these biomarkers to new patient cohorts. There has been no or limited testing in cohorts of high-risk PCa. METHODS AND MATERIALS: We generated transcriptomic data for cohorts of high-risk PCa patients. Patients were treated with ADT followed by external beam radiotherapy with or without a brachytherapy boost. Biomarkers curated from the literature were calculated from pre-treatment biopsy gene expression data. The primary endpoint for survival analyses was biochemical recurrence-free survival (bRFS) and the secondary endpoints were distant metastasis-free survival (DMFS) and overall survival. RESULTS: The performance of the selected biomarkers was poor, with none achieving prognostic significance for bRFS or DMFS in any cohort. The brachytherapy boost cohort received shorter durations of ADT than the conventionally fractionated or hypofractionated cohorts (Wilcoxon rank sum test, p=2.1×10-18 and 2.3×10-10 respectively) and had increased risk of distant metastasis (log-rank test, p=8×10-4). There were no consistent relationships between biomarker score and outcome for any of the endpoints. CONCLUSIONS: Hypoxia and radiosensitivity biomarkers were not prognostic in high-risk PCa patients treated with ADT plus radiotherapy. We speculate that the lack of prognostic capability could be caused by the variable hypoxia-modifying effects of the ADT that these high-risk patients received before and during definitive treatment with radiotherapy. A deeper understanding of biomarker construction, performance and inter-cohort transferability in relation to patient characteristics, sample handling and treatment modalities is required before hypoxia biomarkers can be recommended for routine clinical use in the pre-treatment setting.

Abstract:

BACKGROUND: Obstetric Bleeding Study UK (OBS UK) (award ID: 152057) is a National Institute for Health and Care Research (NIHR)-funded stepped wedge cluster randomised controlled trial of a complex intervention for postpartum haemorrhage. This was developed in Wales and evaluated in a feasibility study, with improvements in maternal outcomes observed. Generalisability of the findings is limited by lack of control data and limited ethnic diversity in the Welsh obstetric patient population compared to the United Kingdom (UK): 94% of the Welsh population identifies as White, versus 82% in the UK. Non-White ethnicity and socioeconomic deprivation are linked to increased risk of adverse maternal outcomes. traditionally, decisions regarding site selection are based on desire to complete trials on target in 'tried and tested' research active institutions. To ensure widespread applicability of the results and investigate the impact of ethnicity and social deprivation on trial outcomes, maternity units were recruited that represent the ethnic diversity and social deprivation profiles of the UK. METHOD: Using routinely collected, publicly available data, an interactive dashboard was developed that demonstrates the demographics of the population served by each maternity unit in the UK, to inform site recruitment. Data on births per year, ethnic and socioeconomic group of the population for each maternity unit, across the UK, were integrated into the dashboard. RESULTS: The dashboard demonstrates that OBS UK trial sites reflect the ethnic and socioeconomic diversity of the UK (study vs UK population ethnicity: White 79.2% vs 81.7%, Asian 10.5% vs 9.3%, Black 4.7% vs 4.0%, Mixed 2.5% vs 2.9%, Other 3.0% vs 2.1%) with variation in site demography, size and location. Missing data varied across sites and nations and is presented. CONCLUSION: The NIHR equality, diversity and inclusion strategy states studies must widen

Abstract:
Background: Machine learning (ML) prediction of clinically isolated syndrome (CIS) conversion to multiple sclerosis (MS) could be used as a remote, preliminary tool by clinicians to identify high-risk patients that would benefit from early treatment. Objective(s): This study evaluates ML models to predict CIS to MS conversion and identifies key predictors. Method(s): Five supervised learning techniques (Naive Bayes, Logistic Regression, Decision Trees, Random Forests and Support Vector Machines) were applied to clinical data from 138 Lithuanian and 273 Mexican CIS patients. Seven different feature combinations were evaluated to determine the most effective models and predictors. Result(s): Key predictors common to both datasets included sex, presence of oligoclonal bands in CSF, MRI spinal lesions, abnormal visual evoked potentials and brainstem auditory evoked potentials. The Lithuanian dataset confirmed predictors identified by previous clinical research, while the Mexican dataset partially validated them. The highest F1 score of 1.0 was achieved using Random Forests on all features for the Mexican dataset and Logistic Regression with SMOTE Upsampling on all features for the Lithuanian dataset. Conclusion(s): Applying the identified high-performing ML models to the CIS patient datasets shows potential in assisting clinicians to identify high-risk patients.
