(Cost-)effectiveness of focal therapy versus radical therapy (standard of care) in the treatment of men with intermediate-risk prostate cancer: study protocol for the ENFORCE focal randomised controlled trial

Background Intermediate-risk prostate cancer (PCa) is currently managed with radical whole-gland therapies, such as radical prostatectomy (RP) or radiotherapy (RT). While effective, these treatments can significantly impact quality of life (QoL), particularly in relation to urinary incontinence and erectile dysfunction. Focal therapy poses a promising alternative for whole-gland treatment in this specific patient population; however, current evidence has primarily been limited to phase I and II studies. Robust prospective evidence is needed to determine whether focal therapy can be considered…

Diagnostic yield and safety of Dual-functIon Semi-rigid thoraCoscOpy Versus rigid thoracoscopy for the diagnosis of plEuRal disease (DISCOVER-2): protocol for a randomised controlled trial

Introduction Rigid thoracoscopy is an established diagnostic instrument for pleural diseases; however, it is limited by challenges related to manoeuvrability, patient comfort and operator learning curve. A novel dual-function semi-rigid thoracoscope with associated semi-rigid forceps has been engineered to integrate the diagnostic efficacy of rigid biopsy forceps with the ergonomic advantages of a semi-rigid system. The Dual-functIon Semi-rigid thoraCoscOpy Versus rigid thoracoscopy for the diagnosis of plEuRal disease trial was designed to evaluate whether this device achieves a diagnostic…

National qualitative study in France to explore parents lived experience at the birth of a child with a large or giant congenital melanocytic nevus

Introduction Congenital melanocytic nevi (CMN) are congenital malformations that cannot be detected by prenatal ultrasounds and may have a significant physical and psychological impact on affected individuals, particularly when they are large. Congenital anomalies are known to impair parental quality of life, which may in turn affect the child’s well-being and development. However, little is known about the feelings and lived experience of parents on the birth of a CMN-affected child. The aim of this study is to describe the lived experience of parents of a child with a large or giant CMN, and…

Does a novel digital self-triage and scheduling pathway reduce wait times for low-acuity emergency department visits in a Canadian community hospital? A prospective cohort study

Objectives The objectives were to evaluate if a novel self-triaging and self-scheduling emergency department (ED) service, the Minor Ailment Patient Pathway (MAPP), can safely reduce ED wait times for low-acuity patients presenting with either cold and influenza or musculoskeletal ailments. Design Prospective cohort study including all consecutive ED patients from 1 June 2023 to 31 March 2024. Outcomes for MAPP patients were compared with contemporaneous, matched ED patients who followed the usual care (UC) ED intake and evaluation process.

Adolescent sexual and reproductive health assessment in clinical practice in India: a qualitative study triangulating clinician practices and young adults experiences

Objectives To characterise current practices in adolescent sexual and reproductive health (SRH) assessment during routine clinical encounters in a tertiary care setting and to triangulate these findings with young adults’ experiences of adolescent healthcare, identifying gaps between recommended assessment approaches and real-world clinical practice. Design Qualitative study using semistructured in-depth interviews (IDIs) and group discussions with clinicians, followed by a sequential triangulation phase involving IDIs with young adults. Data were analysed using Braun and Clarke’s reflexive…

Rationale, design and methods of the Cul-CM study: a protocol for cultural adaptation of contingency management in adults with stimulant use disorder

Introduction Stimulant use disorder is a growing contributor to drug poisoning and mortality in the USA, with disproportionate impact on black communities driven by stimulant-opioid polysubstance use and other structural barriers to treatment. Contingency management (CM) is the most effective evidence-based treatment for stimulant use disorder but remains poorly implemented especially in minoritised communities. Cultural adaptation represents a promising implementation strategy to improve acceptability, engagement and equity of CM while maintaining fidelity to core evidence-based programming…

Tesamorelin as an Adjunct to Exercise for Improving Physical Function in HIV (TRIUMPH): a clinical trial protocol

Background The Tesamorelin as an Adjunct to Exercise for Improving Physical Function in HIV (TRIUMPH) study is a randomised controlled trial with the overall goal of examining the combined effect of exercise and the growth hormone-releasing hormone analogue tesamorelin on physical function. Methods TRIUMPH is a two-site, double-blind, randomised trial of 100 sedentary older adults (aged 50–80 years) living with HIV who are frail or at risk for frailty and have excess abdominal adiposity. Enrolled participants will be randomised to receive tesamorelin or placebo as an adjunct to a home-based…

Development and acceptability of gist-based decision aids for prostate and breast cancer screening: a two-phase qualitative interview study in an online setting

Background Traditional approaches to designing decision aids have focused on providing completeness of information and quantitative detail. An alternative approach based on psychological research emphasises understanding the essence or ‘gist’ of the decision. Few gist-based decision aids exist. The objective of this study was to develop novel gist-based decision aids for prostate and breast cancer screening and evaluate their acceptability. Methods Men aged 40–60 years and women aged 40–49 years eligible for prostate or breast cancer screening were recruited from ResearchMatch (National…

Application of serum neurofilament light chain (sNfL) and glial fibrillary acidic protein (sGFAP) as biomarkers in the clinical management of multiple sclerosis (NeuroFilMS): a protocol for an observational cohort study

Introduction Advances in ultrasensitive assay techniques have enabled precise quantification of serum neurofilament light chain (sNfL) and serum glial fibrillary acidic protein (sGFAP), highlighting their potential as dynamic biomarkers for detecting neuroaxonal injury, disease activity and progression in multiple sclerosis (MS). In the NeuroFilMS study, sNfL is being investigated prospectively as a prognostic biomarker for clinical and radiological disease activity in relapsing MS, while sGFAP is retrospectively explored as a marker of disease progression.

Safety and early efficacy of iPSC-derived motor neuron progenitor cells in subacute spinal cord injury: protocol for a phase I, multicentre, open-label, single-arm trial

Introduction Spinal cord injury (SCI) frequently results in severe neurological impairment due to neural tissue destruction and scarring, representing a substantial and increasing global health burden. Current standard treatments primarily focus on preventing secondary complications but offer limited efficacy in repairing neural circuits or reversing neurological deficits. Stem cell transplantation, particularly using induced pluripotent stem cell (iPSC)-derived therapies, presents a regenerative strategy that avoids the ethical constraints associated with embryonic stem cells while providing…
