Implementation Fidelity of a Smartphone Application for Population-Based General Movement Assessment: The Early Moves Study.

Objective: To describe the infant and maternal characteristics of the Early Moves cohort and to assess representativeness to the general population, and to evaluate the implementation fidelity of an application-based collection of General Movement Assessment (GMA) videos at writhing and fidgety age.

Study Design: Prospective observational study. Mothers who had recently delivered or were enrolled to deliver at maternity hospitals in Perth, Western Australia, were recruited from November 2019 to December 2023.

Dietary lipids are largely deposited in skin and rapidly affect insulating properties.

Skin is a regulatory hub for energy expenditure and metabolism, and alteration of lipid metabolism enzymes in skin impacts thermogenesis and obesogenesis in mice. Here we show that thermal properties of skin are highly reactive to diet: within three days, a high fat diet reduces heat transfer through skin. In contrast, a dietary manipulation that prevents obesity accelerates energy loss through skins.

Development of a Core Outcome Set for Intervention Studies in Adults With Laryngotracheal Stenosis.

Objective: Adult acquired laryngotracheal stenosis (LTS) is a chronic condition with heterogeneous treatment options and a significant symptom burden. Synthesis of data across research studies to guide clinical decision-making is challenging due to inconsistent outcome selection and use of unvalidated measures. Our objective was to establish a core outcome set (COS) for studies of LTS interventions in adults.

Investigating the safety of physical rehabilitation with critically ill patients receiving vasoactive drugs: An exploratory observational feasibility study.

Background: Physical rehabilitation of critically ill patients may improve physical outcomes; however, the relative benefits and risks with patients requiring vasoactive drugs is currently unknown. A feasibility study is needed to inform the design of a future trial required to address this issue.

Methods: A two-phase exploratory observational feasibility study was carried out: A retrospective study to clarify the current practice of rehabilitation with patients receiving vasoactive drugs to inform future trial interventions and design.

A modular protocol for virosome display of subunit vaccine antigens.

Antigen array increases B cell receptor (BCR) triggering and the titer of antibodies elicited by subunit vaccines. Here, we present a protocol for multivalent antigen display by synthetic virosomes: preformed liposomes bearing glycoprotein spike proteins from enveloped viruses. We describe how to customize lipid stoichiometry within preformed liposomes and attach user-defined antigens via covalent and/or non-covalent interactions.

Falls and balance impairment; what and how has this been measured in adults with joint hypermobility? A scoping review.

Background: People with joint hypermobility have excessive joint flexibility, which is more common in young women. The people with symptomatic hypermobility report poor balance and even falls. This scoping review aims to identify and map the available evidence related to balance and falling in adults with joint hypermobility to support research planning and ideas for treatment direction.

Fine-Grained Fidgety Movement Classification Using Active Learning.

Typically developing infants, between the corrected age of 9-20 weeks, produce fidgety movements. These movements can be identified with the General Movement Assessment, but their identification requires trained professionals to conduct the assessment from video recordings. Since trained professionals are expensive and their demand may be higher than their availability, computer vision-based solutions have been developed to assist practitioners.

Differences in Somatosensory Function Related to Hand Dominance: Results of a Quantitative Sensory Testing Study in Healthy Volunteers.

Purpose: Quantitative sensory testing commonly utilizes the unaffected, contralateral side as a control to detect somatosensory dysfunction. There is scant evidence that somatosensory function for the volar dominant and non-dominant hands is equivalent, therefore intra-patient comparisons are unwarranted. This study aimed to identify dominance-related differences in palmar hand somatosensation, thereby determining if the unaffected contralateral hand is a valid comparator in clinical populations.

Assessing the safety of physical rehabilitation in critically ill patients: a Delphi study.

Background: Physical rehabilitation of critically ill patients is implemented to improve physical outcomes from an intensive care stay. However, before rehabilitation is implemented, a risk assessment is essential, based on robust safety data. To develop this information, a uniform definition of relevant adverse events is required.

Dietary lipid is largely deposited in skin and rapidly affects insulating properties.

Skin has been shown to be a regulatory hub for energy expenditure and metabolism: mutations of skin lipid metabolism enzymes can change the rate of thermogenesis and susceptibility to diet-induced obesity. However, little is known about the physiological basis for this function. Here we show that the thermal properties of skin are highly reactive to diet: within three days, a high fat diet reduces heat transfer through skin.

Clinical evaluation of post-surgical scar hyperaesthesia: a longitudinal observational pilot study.

Introduction: The mechanisms underlying persistent scar pain are not fully elucidated and evidence for the clinical evaluation of scar pain is limited. This pilot observational study investigated participation data and sought to identify objective clinical scar evaluation measures for future trials.

Methods: With ethical approval and consent, adults undergoing planned hand surgery were enrolled from one NHS hospital.

Patient and Public Involvement in Technology-Related Dementia Research: Scoping Review.

Background: Technology-related research on people with dementia and their carers often aims to enable people to remain living at home for longer and prevent unnecessary hospital admissions. To develop person-centered, effective, and ethical research, patient and public involvement (PPI) is necessary, although it may be perceived as more difficult with this cohort. With recent and rapid expansions in health and care-related technology, this review explored how and with what impact collaborations between researchers and stakeholders such as people with dementia and their carers have taken place.

Are Clinical Prediction Rules Used in Spinal Cord Injury Care? A Survey of Practice.

Background: Accurate outcome prediction is desirable post spinal cord injury (SCI), reducing uncertainty for patients and supporting personalized treatments. Numerous attempts have been made to create clinical prediction rules that identify patients who are likely to recover function. It is unknown to what extent these rules are routinely used in clinical practice.

The voice and swallowing profile of adults with laryngotracheal stenosis before and after reconstructive surgery: A prospective, descriptive observational study.

Objectives: Airway reconstruction for laryngo tracheal stenosis (LTS) improves dyspnoea. There is little evidence relating to impact upon voice and swallowing. We explored voice and swallowing outcomes in adults with LTS before and after reconstructive surgery.

Clinician and patient perspectives on the barriers and facilitators to physical rehabilitation in intensive care: a qualitative interview study.

Objectives: The objective of this study is to explore patient, relative/carer and clinician perceptions of barriers to early physical rehabilitation in intensive care units (ICUs) within an associated group of hospitals in the UK and how they can be overcome.

Design: Qualitative study using semi-structured interviews and thematic framework analysis.

Setting: Four ICUs over three hospital sites in London, UK.

The citrate transporters SLC13A5 and SLC25A1 elicit different metabolic responses and phenotypes in the mouse.

Cytosolic citrate is imported from the mitochondria by SLC25A1, and from the extracellular milieu by SLC13A5. In the cytosol, citrate is used by ACLY to generate acetyl-CoA, which can then be exported to the endoplasmic reticulum (ER) by SLC33A1. Here, we report the generation of mice with systemic overexpression (sTg) of SLC25A1 or SLC13A5.

Development of a framework and research impact capture tool for nursing, midwifery, allied health professions, healthcare science, pharmacy and psychology (NMAHPPs).

Background: There is an ambitious target to create a UK clinical academic workforce representing 1% of clinicians from nursing, midwifery, the allied health professions, healthcare science, pharmacy and psychology (NMAHPPs). Understanding and recording the impact that clinical academics make across healthcare services is crucial if we are to grow, value and support this highly skilled workforce group. However, it is currently difficult to systematically record, collate and report the impacts associated with NMAHPP research activity.

Reflections on contributing to health research: A qualitative interview study with research participants and patient advisors.

Objectives: The aims of this study were to explore individuals' experiences of contributing to health research and to identify the types of impact that are perceived as important by participants or patient and public advisors. Specifically, research led by NMAHPP clinicians (Nursing, Midwifery, Allied health professions, Healthcare science, Psychology and Pharmacy).

Methods: Semi-structured one-to-one interviews were conducted with health research participants and patient or public advisors.

"Humanizing" mouse environments: Humidity, diurnal cycles and thermoneutrality.

Thermoneutral housing has been shown to promote more accurate and robust development of several pathologies in mice. Raising animal housing temperatures a few degrees may create a relatively straightforward opportunity to improve translatability of mouse models. In this commentary, we discuss the changes of physiology induced in mice housed at thermoneutrality, and review techniques for measuring systemic thermogenesis, specifically those affecting storage and mobilization of lipids in adipose depots.

Enhanced Ribonucleoprotein Immunoprecipitation (RIP) Technique for the Identification of mRNA Species in Ribonucleoprotein Complexes.

RNA binding proteins (RBPs) are critical regulators of cellular phenotypes, and dysregulated RBP expression is implicated in various diseases including cancer. A single RBP can bind to and regulate the expression of many RNA molecules via a variety of mechanisms, including translational suppression, prevention of RNA degradation, and alteration in subcellular localization. To elucidate the role of a specific RBP within a given cellular context, it is essential to first identify the group of RNA molecules to which it binds.

'Is there something wrong with your voice?' A qualitative study of the voice concerns of people with laryngotracheal stenosis.

Background: Acquired laryngotracheal stenosis (LTS) is a rare condition that causes breathlessness and dyspnoea. Patients have reconstructive airway surgery to improve their breathing difficulties, but both LTS and the surgery can cause voice difficulties. The existing evidence base for management of voice difficulties for adults with LTS focuses on symptoms.

Regulation of metabolic health by dietary histidine in mice.

Low-protein (LP) diets are associated with a decreased risk of diabetes in humans, and promote leanness and glycaemic control in both rodents and humans. While the effects of an LP diet on glycaemic control are mediated by reduced levels of the branched-chain amino acids, we have observed that reducing dietary levels of the other six essential amino acids leads to changes in body composition. Here, we find that dietary histidine plays a key role in the response to an LP diet in male C57BL/6J mice.

An investigation of the control of quadriceps in people who are hypermobile; a case control design. Do the results impact our choice of exercise for people with symptomatic hypermobility?

Background: People with symptomatic hypermobility have altered proprioception however, the origin of this is unclear and needs further investigation to target rehabilitation appropriately. The objective of this investigation was to explore the corticospinal and reflex control of quadriceps and see if it differed between three groups of people: those who have symptomatic hypermobility, asymptomatic hypermobility and normal flexibility.

Methods: Using Transcranial Magnetic Stimulation (TMS) and electrical stimulation of peripheral nerves, motor evoked potentials (MEPs) and Hoffman (H) reflexes of quadriceps were evoked in the three groups of people.

Enhanced immunoprecipitation techniques for the identification of RNA-binding protein partners: IGF2BP1 interactions in mammary epithelial cells.

RNA-binding proteins (RBPs) regulate the expression of large cohorts of RNA species to produce programmatic changes in cellular phenotypes. To describe the function of RBPs within a cell, it is key to identify their mRNA-binding partners. This is often done by crosslinking nucleic acids to RBPs, followed by chemical release of the nucleic acid fragments for analysis.
