Association of iron status during early pregnancy and the risk of gestational diabetes: a retrospective cohort study in Shanghai

Background The association between maternal iron status and the risk of gestational diabetes mellitus (GDM) remains elusive. Clearer evidence is needed to inform appropriate ferritin thresholds and iron supplementation guidelines during pregnancy. Objectives To investigate whether first-trimester serum ferritin (SF) concentration is associated with subsequent GDM risk. Design Retrospective cohort study. Setting A tertiary obstetrics and gynaecology hospital in Shanghai, China. Participants A total of 6429 low-risk pregnant women at fewer than 14 weeks of gestation were finally included…

Impact of different degrees of social engagement interventions (DDSEIs) on cognitive performance and brain activity in community-dwelling adults with subjective cognitive decline in Nanjing, China: a randomised controlled trial protocol

Introduction Social isolation may have adverse effects on incidence and severity of cognitive impairment including subjective cognitive decline (SCD). An increase of environmental variety and social interactions may furthermore reduce progression from SCD to dementia. Research evaluating respective interventions is limited, particularly as regards studies comparing different degrees of social engagement interventions. We thus developed a clinical trial protocol to determine the efficacy of social interventions with different intensities in protecting cognitive function and white matter…

Interventional, multicentre investigation of a novel lumbar total joint replacement: propensity matched study design and protocol

Introduction The study aims to demonstrate non-inferior clinical success (safety and efficacy) of the MOTUS Total Joint Replacement device relative to posterior or transforaminal lumbar interbody fusion with respect to a composite endpoint. The primary hypothesis for this study is that the probability of achieving 24-month composite clinical success (CCS) for subjects receiving the investigational device is not clinically inferior to the probability of achieving 24-month CCS for subjects receiving lumbar interbody fusion collected in a separate real-world evidence (RWE) study. Methods and…

Incidence of respiratory syncytial virus in adults >=50 years during and following the COVID-19 pandemic in upper midwest USA: a community-based prospective cohort study

Objective Respiratory syncytial virus (RSV) is an important viral pathogen in children, older adults and adults with certain high-risk conditions. In our prospective community-based cohort study of adults 50 years and older before the COVID-19 pandemic, the incidence of RSV acute respiratory infection (ARI) was 48.6 cases/1000 person-years (PY), which decreased to near zero during the COVID-19 pandemic. Our objective was to determine the incidence of RSV-ARI during the 2 years following the initial phase of the pandemic (2021–2022 and 2022–2023). Design This is a community-based prospective…

Understanding the implementation of kidney supportive care interventions to improve palliative care outcomes for adults receiving haemodialysis: protocol for a rapid realist review

Introduction Chronic kidney disease (CKD) is a significant global health concern, contributing substantially to mortality; in advanced stages, adults often require kidney supportive care (KSC), a model of care/intervention that addresses complex palliative and supportive needs. These needs often remain insufficiently addressed, particularly among adults receiving haemodialysis, due to the interplay of multiple contextual factors and inconsistent reported outcomes. Consequently, it remains unclear how, for whom and under what circumstances KSC works (or does not work). Therefore, this rapid…

Rationale and design of a prospective cohort study and biobank of the offspring born to mothers with a solid organ transplant: protocol for the TransplantLines Next Generation study

Introduction Successful pregnancies with healthy newborns have been reported after all types of solid organ transplantation (SOT). Limited data in young children suggest similar development and health compared with the general population. However, fetal development may be influenced by factors such as immunosuppressive medication and the increased incidence of pregnancy complications, and forthcoming health problems may only become apparent later in the life of the offspring. To allow for better investigation of the long-term health of offspring born after SOT, we designed the Transplantlines…

Cluster randomised feasibility trial of PRISM: the PRimary Care Individual Social Norms MSK Data Dashboard to support first contact physiotherapy management of musculoskeletal patients in primary care

Introduction Musculoskeletal (MSK) conditions affect over 20 million people in the UK and account for one in seven General Practitioner (GP) consultations. To address capacity challenges, First Contact Physiotherapists (FCPs) now manage MSK patients in primary care. However, FCPs working in isolation from physiotherapy teams exhibit broad variation in decision-making that could pose risks to care quality. PRimary Care Individual Social Norms MSK Data Dashboard (PRISM) is a clinician-facing behaviour change digital dashboard that provides individualised social norms feedback such as, ‘you are…

Temporal trends in epidemiology and patient characteristics of 36 cancers: a protocol for a multinational population-based cohort study using OMOP-standardised databases to investigate CANcer (OMOPCAN)

Introduction Cancer registries remain the gold standard for global cancer monitoring, yet complementing them with electronic health records and claims can significantly enhance the understanding of the cancer burden by providing a more complete picture of the patient journey. The main aim of this project is to serve as a proof of concept for using real-world data mapped to the Observational Medical Outcomes Partnership (OMOP) common data model (CDM) to monitor cancer epidemiology over time and characterise patients’ clinical history and outcomes. Methods and analysis This study will be…

Comparison of a four-nerve block protocol versus adductor canal block plus local infiltration analgesia for primary total knee arthroplasty in two French private hospitals: protocol for the multicentre randomised INCA trial

Background INCA is a multicentre, prospective, randomised, two-arm superiority trial. 100 adult patients scheduled for primary total knee arthroplasty (TKA) will be randomised 1:1 to one of two locoregional analgesia strategies: group 1 (standard strategy), single-shot adductor canal block (ACB) combined with active surgeon-administered peri-articular infiltration with ropivacaine and participant-facing sham peripheral nerve blocks; group 2 (four-nerve block strategy), single-shot ACB combined with three additional ultrasound-guided nerve blocks (lateral femoral cutaneous, obturator and…

Efficacy of high-flow nasal cannula versus conventional face mask oxygen therapy on ipsilateral cerebral haemodynamics during the immediate post-extubation phase following carotid endarterectomy: protocol for a randomised controlled trial

Introduction Cerebral hyperperfusion syndrome (CHS) is a severe complication following carotid endarterectomy (CEA). During emergence from general anaesthesia, residual anaesthetics induce mild respiratory depression and carbon dioxide accumulation, exacerbating hyperperfusion risks via hypercapnia-induced cerebral vasodilation. High-flow nasal cannula (HFNC) effectively reduces excessively elevated pressure of arterial carbon dioxide via multiple mechanisms including anatomical dead space washout. This trial aims to evaluate the effects of HFNC versus conventional mask oxygen therapy on…

Prophylactic antiseizure medication administration practices in neonates with hypoxic-ischaemic encephalopathy: a scoping review protocol

Introduction Hypoxic-ischaemic encephalopathy (HIE) is a leading cause of neonatal mortality and long-term neurodevelopmental impairment worldwide. Neonatal seizures are common in HIE and are associated with adverse outcomes. While antiseizure medications are routinely used for treatment, their prophylactic use in the absence of clinically evident seizures remains controversial, with limited consensus and variable clinical practices. Therefore, this review will map the existing evidence concerning the utilisation of antiseizure medication for prophylaxis among neonates with HIE. Methods and…
