Associations between skeletal muscle mass and elevated blood pressure are independent of body fat: a cross-sectional study in young adult women of African ancestry.

Although research on the relationship between lean body mass and blood pressure (BP) has been inconsistent, most studies reported that measures of lean body mass are associated with a higher risk of hypertension. We explored relationships between body composition (fat and skeletal muscle mass) and BP in 1162 young adult African women. DXA-derived measures of whole body, central and arm fat mass were associated with higher systolic and diastolic BP, while leg fat percentage was associated with lower systolic and diastolic BP.

A systematic review of variables associated with snakebite risk in spatial and temporal analyses.

Background: Snakebite is a priority neglected tropical disease, but incidence data are lacking; current estimates rely upon incomplete health facility reports or ad hoc surveys. Spatial analysis methods harness statistical associations between case incidence and spatially varying factors to improve estimates. This systematic review aimed to identify variables associated with snakebite risk in spatial and temporal analyses for inclusion in geospatial studies to improve risk estimation accuracy.

ECM Modifications Driven by Age and Metabolic Stress Directly Promote the Vascular Smooth Muscle Cell Osteogenic Processes.

Background: The ECM (extracellular matrix) provides the microenvironmental niche sensed by resident vascular smooth muscle cells (VSMCs). Aging and disease are associated with dramatic changes in ECM composition and properties; however, their impact on the VSMC phenotype remains poorly studied.

Methods: Here, we describe a novel in vitro model system that utilizes endogenous ECM to study how modifications associated with age and metabolic disease impact the VSMC phenotype.

The alleviating specific phobias in children trial: Challenges and solutions to implementing a randomized controlled trial in clinical services.

In 2015, The Alleviating Specific Phobias Experienced by Children Trial (ASPECT) was commissioned by the National Institute for Health and Care Research (NIHR) to compare the clinical and cost-effectiveness of multi-session Cognitive Behavioral Therapy (CBT) for specific phobias in children and young people (CYP) (aged 7-16), with a briefer variant called One Session Treatment (OST). From 2016 to 2020, ASPECT recruited = 274 CYP with specific phobias and their families from across England, including 26 Child and Adolescent Mental Health Services (CAMHS) centres, three voluntary sector centers and one University-based wellbeing service. Whilst the trial successfully reached its recruitment target, the challenges experienced in its delivery highlight the difficulties of embedding child and adolescent research into clinical settings and routine practice.

Current perspectives and the future of disease-modifying therapies in type 1 diabetes.

Use of immunomodulating agents to prevent the progression of autoimmune β-cell damage leading to type 1 diabetes mellitus (T1DM) is an interesting area for research. These include non-specific anti-inflammatory agents, immunologic vaccination and anti-inflammatory agents targeting specific immune cells or cytokines. Teplizumab is an anti-CD3-molecule that binds to and leads to the disappearance of the CD3/TCR complex and rendering the T cell anergic to its target antigen.

Association between age at diagnosis of diabetes and ocular disease: Insights from a recent article.

In this article, we discuss Ye 's recent article on the association between age at diabetes diagnosis and subsequent risk of age-related ocular diseases. The study, which utilized United Kingdom Biobank data, highlighted a strong link between early diabetes onset and major eye conditions, such as cataracts, glaucoma, age-related macular degeneration, and vision loss, independent of glycemic control and disease duration. This finding challenges the previous belief that diabetic eye disease primarily correlates with hyperglycemia.

Field testing of recombinant subunit vaccines against in lambing ewes demonstrates a lack of efficacy in the face of a multi-species parasite challenge.

Introduction: We previously demonstrated efficacy of an 8-antigen recombinant subunit vaccine against a single species homologous challenge in lambs and in lambing ewes in pen trials. We subsequently demonstrated efficacy of a simplified, 2-antigen, version of this vaccine in lambs in pen trials. Here, we test both vaccines in lambing ewes in a field setting.

Transcriptome analysis reveals molecular targets of erythrocyte invasion phenotype diversity in natural isolates from Cameroon.

Further understanding of the molecular mediators of alternative RBC invasion phenotypes in endemic malaria parasites will support malaria blood-stage vaccine or drug development. This study investigated the prevalence of sialic acid (SA)-dependent and SA-independent RBC invasion pathways in endemic parasites from Cameroon and compared the schizont stage transcriptomes in these two groups to uncover the wider repertoire of transcriptional variation associated with the use of alternative RBC invasion pathway phenotypes. A two-color flow cytometry-based invasion-inhibition assay against RBCs treated with neuraminidase, trypsin, and chymotrypsin and deep RNA sequencing of schizont stages harvested in the first replication cycle in culture were employed in this investigation.

Understanding the species and their challenges to animal health and livestock species for informed development of new, specific treatment strategies.

species are parasitic organisms of vertebrates with a worldwide distribution. They have an important impact globally upon human and animal health, and livestock productivity. The life cycle of these species is complex and difficult to disrupt to improve human health, animal health, food security and economic growth.

From laboratory to clinical practice: an update of the immunological and molecular tools for neurocysticercosis diagnosis.

Neurocysticercosis (NCC) is caused by the invasion of larvae in the central nervous system (CNS) and stands as the predominant cause of epilepsy and other neurological disorders in many developing nations. NCC diagnosis is challenging because it relies on brain imaging exams (CT or MRI), which are poorly available in endemic rural or resource-limited areas. Moreover, some NCC cases cannot be easily detected by imaging, leading to inconclusive results.

Incidence and Progression of Diastolic Dysfunction in People With HIV in Tanzania: A Comparative Cohort.

Background: People living with HIV (PLWH) have a higher prevalence of diastolic dysfunction and left ventricular hypertrophy (LVH) in cross-sectional studies. Longitudinal data are lacking, especially from Africa.

Objectives: The aim was to examine: 1) the incidence of diastolic dysfunction in PLWH compared to community controls in Tanzania; 2) the progression of diastolic function and LVH in PLWH after antiretroviral therapy initiation; and 3) traditional, endemic, and HIV-specific risk factors for diastolic function and LVH.

Antifouling Copper Surfaces Interfere with Wet Chemical Nitrate Sensors: Characterization and Mechanistic Investigation.

Wet chemical sensors autonomously sample and analyze water using chemical assays. Their internal fluidics are not susceptible to biofouling (the undesirable accumulation of microorganisms, algae, and animals in natural waters) due to the harsh chemical environment and dark conditions; however, the sample intake and filter are potentially susceptible. This paper describes the use of copper intake filters, incorporated to prevent fouling, on two different wet chemical nitrate sensors that each use different variants of the Griess assay (in particular, different nitrate reduction steps) to quantify nitrate concentrations.

Echocardiography of the right heart in pulmonary arterial hypertension: insights from the ULTRA RIGHT VALUE study.

Aims: Outcome in pulmonary arterial hypertension (PAH) is determined by right ventricular (RV) function adaptation to increased afterload. Echocardiography is easily available to assist bedside evaluation of the RV. However, no agreement exists about the feasibility and most relevant measurements.

Characterization of preclinical models to investigate spinal cord stimulation for neuropathic pain: a systematic review and meta-analysis.

Despite advancements in preclinical and clinical spinal cord stimulation (SCS) research, the mechanisms of SCS action remain unclear. This may result from challenges in translatability of findings between species. Our systematic review (PROSPERO: CRD42023457443) aimed to comprehensively characterize the important translational components of preclinical SCS models, including stimulating elements and stimulation specifications.

Individuals with developmental disabilities make their own stylistic contributions to text written with physical facilitation.

Introduction: For individuals with developmental disabilities (DD) such as autism, Down syndrome, or cerebral palsy, learning to express with language is a two-fold challenge because atypical cognitive capacity is compounded by sensorimotor coordination deficits. One approach to assisting linguistic expression in these individuals is to physically support them, for example, by touching their torso or arm as they type. The neurophysiological mechanism of such motor assistance for linguistic expression is not known, but recently it has been proposed that light touch may reduce the cognitive load associated with the sensorimotor coordination of typing, thereby releasing shared cognitive resources to the task of generating content.
