Management of intraoperatively identified small bile duct stones in patients undergoing cholecystectomy.

Introduction: The management of CBDS (common bile duct stones) in patients with co-existing gallbladder stones has been debated. Guidelines recommend patients with CBDS identified on imaging should be offered duct clearance; however, this is based on low-quality evidence. This study aimed to investigate the natural history of small CBDS identified using IOUS (intraoperative ultrasound) in patients undergoing cholecystectomy.

Different categories of VO kinetics in the 'extreme' exercise intensity domain.

The aim of this study was to classify potential sub-zones within the extreme exercise domain. Eight well-trained male cyclists participated in this study. The upper boundary of the severe exercise domain (P) was estimated by constant-work-rate tests.

Gestational diabetes mellitus in Cameroon: prevalence, risk factors and screening strategies.

Background: The burden of gestational diabetes (GDM) and the optimal screening strategies in African populations are yet to be determined. We assessed the prevalence of GDM and the performance of various screening tests in a Cameroonian population.

Methods: We carried out a cross-sectional study involving the screening of 983 women at 24-28 weeks of pregnancy for GDM using serial tests, including fasting plasma (FPG), random blood glucose (RBG), a 1-hour 50g glucose challenge test (GCT), and standard 2-hour oral glucose tolerance test (OGTT).

Effect of parental touch on relieving acute procedural pain in neonates and parental anxiety (Petal): a multicentre, randomised controlled trial in the UK.

Background: Touch interventions such as massage and skin-to-skin contact relieve neonatal pain. The Parental touch trial (Petal) aimed to assess whether parental stroking of their baby before a clinically required heel lance, at a speed of approximately 3 cm/s to optimally activate C-tactile nerve fibres, provides effective pain relief.

Methods: Petal is a multicentre, randomised, parallel-group interventional superiority trial conducted in the John Radcliffe Hospital (Oxford University Hospitals NHS Foundation Trust, Oxford, UK) and the Royal Devon and Exeter Hospital (Royal Devon University Healthcare NHS Foundation Trust, Exeter, UK).

Genome-wide association analysis of composite sleep health scores in 413,904 individuals.

Recent genome-wide association studies (GWASs) of several individual sleep traits have identified hundreds of genetic loci, suggesting diverse mechanisms. Moreover, sleep traits are moderately correlated, and together may provide a more complete picture of sleep health, while also illuminating distinct domains. Here we construct novel sleep health scores (SHSs) incorporating five core self-report measures: sleep duration, insomnia symptoms, chronotype, snoring, and daytime sleepiness, using additive (SHS-ADD) and five principal components-based (SHS-PCs) approaches.

What motivates public collaborators to become and stay involved in health research?

Background: People with lived experience of health and illness are increasingly being involved in research. Knowing what creates interest in becoming involved in health research may help identify appropriate ways of facilitating meaningful involvement. The study aimed to investigate why people became public collaborators in health research and what helped sustain their commitment to staying involved.

The influence of postural threat-induced anxiety on locomotor learning and updating.

The ability to adapt our locomotion in a feedforward (i.e., "predictive") manner is crucial for safe and efficient walking behavior.

Behavioural intervention to promote the uptake of planned care in urgent dental care attenders: a feasibility randomised controlled trial.

Background: Urgent dental care may be the only place where many people, especially vulnerable groups, access care. This presents an opportunity for delivery of a behavioural intervention promoting planned dental visiting, which may help address one of the factors contributing to a socio-economic gradient in oral health. Although we know that cueing events such as having a cancer diagnosis may create a 'teachable moment' stimulating positive changes in health behaviour, we do not know whether delivering an opportunistic intervention in urgent dental care is feasible and acceptable to patients.

Primary care provision for young people with ADHD: a multi-perspective qualitative study.

Background: Attention deficit hyperactivity disorder (ADHD) is a highly prevalent neurodevelopmental disorder. UK guidance states that primary care has a vital role in effective ADHD management, including referral, medication prescribing and monitoring, and providing broader mental health and wellbeing support. However, many GPs feel unsupported to provide health care for young people with ADHD.

Mediators of the effects of exercise and manual therapy for people with knee and hip osteoarthritis: A secondary, exploratory analysis of the MOA trial.

Objective: To explore whether pain beliefs and functional strength mediate the treatment effect of manual therapy (MT) and exercise therapy (ET) on the Western Ontario and McMaster Osteoarthritis Index (WOMAC) composite scores and its subscales in individuals with hip and/or knee osteoarthritis in the MOA trial.

Design: Secondary analysis of a randomised controlled trial that compared the incremental effects of supervised MT and ET in addition to usual care in patients with osteoarthritis of the hip or knee. 206 participants enrolled in the MOA trial were analysed.

Optimal timing of faculty teaching when combined with near-peer teaching: A mixed methods analysis.

Background: Near-peer teaching is increasingly used in medical education, supporting or replacing faculty teaching. It has positive aspects for learners and tutors, some of which are explained by higher social and cognitive congruence between learners and near-peer tutors (NPTs). This study investigates the optimal combination of faculty tutors (FTs) and NPTs in an abdominal ultrasound course.

Risk factor associations for severe COVID-19, influenza and pneumonia in people with diabetes to inform future pandemic preparations: UK population-based cohort study.

Objective: This study aimed to compare clinical and sociodemographic risk factors for severe COVID-19, influenza and pneumonia, in people with diabetes.

Design: Population-based cohort study.

Setting: UK primary care records (Clinical Practice Research Datalink) linked to mortality and hospital records.

Cost Effectiveness of Endovascular Ultrasound Renal Denervation in Patients with Resistant Hypertension.

Background: Resistant hypertension (rHTN) is defined as blood pressure (BP) of ≥ 140/90 mmHg despite treatment with at least three antihypertensive medications, including a diuretic. Endovascular ultrasound renal denervation (uRDN) aims to control BP alongside conventional BP treatment with antihypertensive medication. This analysis assesses the cost effectiveness of the addition of the Paradise uRDN System compared with standard of care alone in patients with rHTN from the perspective of the United Kingdom (UK) health care system.

Neurodevelopmental functions of CHD8: new insights and questions.

Heterozygous, de novo, loss-of-function variants of the CHD8 gene are associated with a high penetrance of autism and other neurodevelopmental phenotypes. Identifying the neurodevelopmental functions of high-confidence autism risk genes like CHD8 may improve our understanding of the neurodevelopmental mechanisms that underlie autism spectrum disorders. Over the last decade, a complex picture of pleiotropic CHD8 functions and mechanisms of action has emerged.

Parental experience of neonatal pain research while participating in the Parental touch trial (Petal).

Parental involvement in neonatal comfort care is a core component of family-centred care. Yet, parents experience a range of positive and negative feelings when providing pain-relieving interventions for their infants. Parents of infants who participated in the Parental touch trial ( Petal ), a multicentre randomised controlled trial investigating the impact of gentle parental touch on neonatal pain, were asked to complete an anonymous survey.

Correlates of felt age in caregivers of people with dementia: findings from the IDEAL study.

Objective: Family relationships influence how people appraise their own aging and how their appraisals impact their health. We analyzed felt age (FA) among family caregivers of people with dementia.

Methods And Measures: We used a stratified sample of 1,020 spousal and 202 adult-child caregivers from the IDEAL study.

The relationship between playing musical instruments and cognitive trajectories: Analysis from a UK ageing cohort.

Background: The accumulation of age-associated cognitive deficits can lead to Mild Cognitive Impairment (MCI) and dementia. This is a major public health issue for the modern ageing population, as it impairs health, independence and overall quality of life. Keeping the brain active during life has been associated with an increased cognitive reserve, therefore reducing the risk of cognitive impairment in older age.

Telephone-Based Training Intervention for Using Digital Communication Technologies for Social Housing Residents During the COVID-19 Pandemic: Mixed Methods Feasibility and Acceptability Evaluation.

Background: In an era in which digital communication technologies play a pivotal role in everyday life, social housing residents remain highly susceptible to digital exclusion.

Objective: This study aims to evaluate the feasibility and acceptability of a telephone-based training intervention designed to empower people to confidently use digital communication technologies (ie, video calls and web-based messaging).

Methods: Conducted in collaboration with a UK social housing association, the intervention was facilitated by a unitary authority's Digital Inclusion Team during the COVID-19 pandemic.

Quantifying the proportion of different cell types in the human cortex using DNA methylation profiles.

Background: Due to interindividual variation in the cellular composition of the human cortex, it is essential that covariates that capture these differences are included in epigenome-wide association studies using bulk tissue. As experimentally derived cell counts are often unavailable, computational solutions have been adopted to estimate the proportion of different cell types using DNA methylation data. Here, we validate and profile the use of an expanded reference DNA methylation dataset incorporating two neuronal and three glial cell subtypes for quantifying the cellular composition of the human cortex.
