Clinical Manifestations.

Background: Remote unsupervised cognitive assessments have the potential to complement and facilitate cognitive assessment in clinical and research settings.

Method: Here we evaluate the usability, validity and reliability of unsupervised remote memory assessments via mobile devices (see Figure 1) in individuals without dementia from the Swedish BioFINDER-2 study and explore their prognostic utility regarding future cognitive decline in combination with a plasma marker for p-tau217.

Result: Usability was rated positively.

Clinical Manifestations.

Background: Speech and language impairments are associated with cognitive decline in neurodegenerative dementias, particularly Alzheimer's Disease (AD), where subtle speech changes may precede clinical dementia onset. As clinical trials prioritize early identification for disease-modifying treatments, digital biomarkers for timely screening become imperative. Digital speech-based biomarkers can be employed for screening populations at the earliest AD stages.

Spatiotemporal single-cell roadmap of human skin wound healing.

Wound healing is vital for human health, yet the details of cellular dynamics and coordination in human wound repair remain largely unexplored. To address this, we conducted single-cell multi-omics analyses on human skin wound tissues through inflammation, proliferation, and remodeling phases of wound repair from the same individuals, monitoring the cellular and molecular dynamics of human skin wound healing at an unprecedented spatiotemporal resolution. This singular roadmap reveals the cellular architecture of the wound margin and identifies FOSL1 as a critical driver of re-epithelialization.

Psychological interventions for patients with delirium in intensive care: A scoping review protocol.

The objective of this scoping review is to investigate psychological interventions developed, evaluated, and considered for patients with delirium in intensive care units (ICU). Data will be extracted from sources of evidence that address interventions for delirium-related distress and/or cognitive impairments in the adult ICU population, suitable for delivery by or under the supervision of a psychological practitioner. ICU delirium is a common and impactful condition that adversely affects patient outcomes, including prolonged hospitalisation and deteriorating mental health.

Diagnostic interobserver variability of atypia assessment in columnar cell lesions among a group of expert breast pathologists in the United Kingdom and the Republic of Ireland, on behalf of the UK national coordinating committee for breast pathology.

Aims: Atypical ductal hyperplasia and flat epithelial atypia (FEA) have defined diagnostic criteria, yet there is variation in the interpretation of these criteria, particularly when the atypia is present in a background of columnar cell lesions (CCLs). This study focuses upon cases which are especially challenging or difficult to classify reproducibly according to existing criteria.

Methods And Results: Thirteen breast pathology experts were asked to classify 10 challenging cases with CLLs as atypical or non-atypical.

Novel approach using automated target enrichment enables culture-independent accurate whole-genome sequencing of Neisseria gonorrhoeae directly from clinical urogenital and extragenital specimens.

Objectives: Antimicrobial resistance (AMR) in Neisseria gonorrhoeae is compromising gonorrhoea treatment, and enhanced N. gonorrhoeae AMR and genome-based epidemiological surveillance is imperative. Molecular tests are replacing N.

The long-lasting impacts of the COVID-19 pandemic on population-based cancer survival: what are the implications for data analysis?

Monitoring trends of cancer incidence, mortality and survival is vital for the planning and delivery of health services, and the evaluation of diagnostics and treatment at the population level. Furthermore, comparisons are often made between population subgroups to explore inequalities in outcomes. During the COVID-19 pandemic routine delivery of health services were severely disrupted.

Defining Mental Health Conditions Within Primary Care Data: A Validation Study With a Mixed Qualitative and Quantitative Approach.

Objectives: To validate codelists for defining a range of mental health (MH) conditions with primary care data, using a mixed qualitative and quantitative approach and without requiring external data.

Methods: We validated Read codelists, selecting and classifying them in three steps. The qualitative step included an in-depth revision of the codes by six doctors.

Research Priorities for Autonomous Sensory Meridian Response: An Interdisciplinary Delphi Study.

Autonomous Sensory Meridian Response (ASMR) is a multisensory experience most often associated with feelings of relaxation and altered consciousness, elicited by stimuli which include whispering, repetitive movements, and close personal attention. Since 2015, ASMR research has grown rapidly, spanning disciplines from neuroscience to media studies but lacking a collaborative or interdisciplinary approach. To build a cohesive and connected structure for ASMR research moving forwards, a modified Delphi study was conducted with ASMR experts, practitioners, community members, and researchers from various disciplines.

The effect of haemoglobin and blood transfusion on preterm infant gut perfusion and injury.

Introduction: There is significant uncertainty regarding the role that anaemia or red blood cell transfusion (RBCT) plays in the development of gut injury in preterm infants. This study evaluated Near Infrared Spectroscopy (NIRS) together with a range of known biomarkers of gut inflammation to identify their relationship with anaemia and RBCT.

Method: A prospective observational study of preterm infants born at <30 weeks gestation was conducted from birth until either 36 weeks post conceptional age or discharge home.

Risk of adverse cardiovascular events based on common genetic variants in 8-year follow-up of the LIPIDOGEN2015 population using the polygenic risk score (PRS): study design and methodology.

Introduction: Classical risk factors such as hypertension, hypercholesterolemia, pre-diabetes, diabetes and obesity can predict adverse cardiovascular events, but they are less prognostic in patients aged < 60 years. Polygenic risk scores (PRS) can be effective in predicting adverse coronary events in younger and middle-aged patients. Our main aim is to assess the utility of a new PRS created for the Polish population in predicting mortality during an 8-year follow-up in the nationwide LIPIDOGEN2015 population.

The ZFHX3 GGC Repeat Expansion Underlying Spinocerebellar Ataxia Type 4 has a Common Ancestral Founder.

Background: The identification of a heterozygous exonic GGC repeat expansion in ZFHX3 underlying spinocerebellar ataxia type 4 (SCA4) has solved a 25-year diagnostic conundrum. We used adaptive long-read sequencing to decipher the pathogenic expansion in the index Utah family and an unrelated family from Iowa of Swedish ancestry. Contemporaneous to our discovery, other groups identified the same repeat expansion in affected individuals from Utah, Sweden, and Germany, highlighting the current pivotal time for detection of novel repeat expansion disorders.

50% body weight loading reduces stature increases and lumbar disc expansion from 4 h hyper-buoyancy floatation versus 15 min sitting upright.

Microgravity is associated with stature increases, back pain and post-flight intervertebral disc (IVD) herniation. This study aims to determine whether 30 s seated 50% body weight (BW) axial loading is comparable to 15 min sitting upright in 1 g upon changes in stature, anterior lumbar IVD height (via ultrasound), passive vertebral stiffness (VS), and back pain induced by 4 h hyper-buoyancy floatation (HBF) unloading. Sixteen (seven male) healthy volunteers had stature, lumbar IVD height (L2-S1), passive VS (C1-L5) and back pain assessed before and following 4 h HBF, and immediately after participants performed a 30 s seated squat with 50% of their BW or 15 min sitting upright.

Single Cell Data Enables Dissecting Cell Types Present in Bulk Transcriptome Data.

The quality of organoid models can be assessed by single-cell-RNA-sequencing (scRNA-seq) but often only bulk transcriptome data is available. Here we present a pipeline for the analysis of scRNA-seq data and subsequent "deconvolution," which is a method for estimating cell type fractions in bulk transcriptome data based on expression profiles and cell types found in scRNA-seq data derived from biopsies. We applied this pipeline on bulk iPSC-derived kidney and brain organoid transcriptome data to identify cell types employing two scRNA-seq kidney datasets and one brain dataset.

Griscelli Syndrome Type 2: Comprehensive Analysis of 149 New and Previously Described Patients with RAB27A Deficiency.

Griscelli syndrome type 2 (GS2) is a rare, life-threatening immunodysregulatory disorder characterised by impaired cytotoxic activity leading to susceptibility to haemophagocytic lymphohistiocytosis (HLH) and hypopigmentation. We completed a literature review and analysis of clinical data of 149 patients with GS2 including 8 new patients.We identified three founder mutations which show diverse phenotypic profiles (RAB27A c.

Evaluating hippocampal replay without a ground truth.

During rest and sleep, memory traces replay in the brain. The dialogue between brain regions during replay is thought to stabilize labile memory traces for long-term storage. However, because replay is an internally driven, spontaneous phenomenon, it does not have a ground truth - an external reference that can validate whether a memory has truly been replayed.

Kinin B1- and B2-Receptor Subtypes Contract Isolated Bovine Ciliary Muscle: Their Role in Ocular Lens Function and Intraocular Pressure Reduction.

Bradykinin is an endogenously produced nonapeptide with many physiological and pathological functions that are mediated by two pharmacologically defined receptor subtypes, B1- and B2-receptors. Current studies sought to characterize the functional bradykinin (BK) receptors present in freshly isolated bovine ciliary muscle (BCM) using an organ-bath tissue contraction system. Cumulative longitudinal isometric tension responses of BCM strips (4-5 mm) were recorded before and after the addition of test compounds to BCM strips hooked up to an isometric strain gauge transducer system.

Co-Production Within Academic Constraints: Insights from a Case Study.

Co-production in research offers the potential for multiple benefits, including amplifying the voices of the marginalised, reducing power inequalities between academic researchers and co-researchers outside of academia, increased likelihood of impact, and improvement in the research process. But alongside increased interest in co-production, there is increased awareness of its contextual constraints. Key amongst these are institutional orthodoxies in academia, including time-limited, project-based research and precarious employment for junior researchers.
