Background: Kidney disease is common in heart failure with preserved ejection fraction (HFpEF). However, the biologic correlates and prognostic significance of kidney injury (KI), in HFpEF, beyond the estimated glomerular filtration rate (eGFR), are unclear.

Methods And Results: Using baseline plasma samples from the TOPCAT (Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist) trial, we measured the following KI biomarkers: cystatin-C, fatty acid-binding protein-3, Beta-2 microglobulin, neutrophil gelatinase-associated lipocalin, and kidney-injury molecule-1.

Background: The role of cellular senescence in human heart failure (HF) remains unclear. The senescence-associated secretory phenotype (SASP) is composed of proteins released by senescent cells. We assessed the prognostic significance and biologic pathways associated with the SASP in human HF using a plasma proteomics approach.

Back pain is the leading cause of disability globally and results in a substantial medical and economic burden. Epidural steroid injections (ESIs) have been widely used as a treatment for back pain with radiculopathy of various etiologies. Ultrasound guidance (UG) for delivering ESIs can reduce costs and facilitate the procedure in resource-limited settings compared to the current standard technique of using fluoroscopic guidance (FG).

Introduction: The bidirectional relationship between disease activity and mental health in inflammatory bowel disease (IBD) has prompted investigations into the efficacy of psychotherapeutic interventions such as acceptance and commitment therapy (ACT) on biopsychosocial outcomes. We aimed to examine the efficacy of an ACT program (intervention) in comparison with a cognitive behavioral therapy-informed psychoeducation program (active control) for individuals with IBD and coexistent psychological distress. Both programs were delivered online through a hybrid format (i.

Article Synopsis
  • The ENIGMA research consortium focuses on determining the clinical significance of variants in hereditary breast and ovarian cancer genes, specifically BRCA1 and BRCA2, and evolved from an external expert panel to an internal Variant Curation Expert Panel (VCEP) to enhance alignment with FDA recognized classification processes.
  • The VCEP reviewed existing classification criteria and utilized statistical methods to assess evidence strength, testing new specifications on variants and updating documentation for better user clarity.
  • Analysis led to refined classifications for variants—resolving uncertainties and maintaining confidence in others—while revealing gaps in both ENIGMA's research and ACMG/AMP criteria, ultimately improving the classification process for BRCA1 and BRCA2 variants.

Background: Atopic dermatitis (eczema), can have a significant impact on well-being and quality of life for affected people and their families. Standard treatment is avoidance of triggers or irritants and regular application of emollients and topical steroids or calcineurin inhibitors. Thorough physical and psychological assessment is central to good-quality treatment.

The progression of Parkinson's disease (PD) is associated with microstructural alterations in neural pathways, contributing to both motor and cognitive decline. However, conflicting findings have emerged due to the use of heterogeneous methods in small studies. Here we performed a large diffusion MRI study in PD, integrating data from 17 cohorts worldwide, to identify stage-specific profiles of white matter differences.

Background: Unsupervised machine learning describes a collection of powerful techniques that seek to identify hidden patterns in unlabeled data. These techniques can be broadly categorized into dimension reduction, which transforms and combines the original set of measurements to simplify data, and cluster analysis, which seeks to group subjects based on some measure of similarity. Unsupervised machine learning can be used to explore alternative subtyping of disorders of gut-brain interaction (DGBI) compared to the existing gastrointestinal symptom-based definitions of Rome IV.

  • A study forecasts a 91.2% increase in crude cardiovascular disease (CVD) mortality in Asia from 2025 to 2050, despite a 23.0% decrease in the age-standardized mortality rate.
  • Ischaemic heart disease and stroke will remain the top causes of mortality, with Central Asia experiencing the highest mortality rates while high systolic blood pressure is identified as the leading risk factor across most of Asia.
  • The research highlights the need for targeted health interventions due to the significant variations in CVD burden across different regions in Asia.

In recent years, a novel x-ray imaging modality has emerged that reveals unresolved sample microstructure via a "dark-field image", which provides complementary information to conventional "bright-field" images, such as attenuation and phase-contrast modalities. This x-ray dark-field signal is produced by unresolved microstructures scattering the x-ray beam resulting in localised image blur. Dark-field retrieval techniques extract this blur to reconstruct a dark-field image.

Article Synopsis
  • The study aimed to analyze the disease, demographic, and imaging characteristics linked to different types of calcium pyrophosphate deposition (CPPD) disease, focusing on recurrent acute CPP crystal arthritis, chronic CPP crystal inflammatory arthritis, and crowned dens syndrome (CDS).
  • Researchers utilized data from an international cohort of 618 individuals to investigate the phenotypic traits of each type of CPPD and performed multivariable logistic regression to assess associations between risk factors and inflammatory phenotypes.
  • Key findings indicated that longer disease duration correlated with recurrent acute arthritis, while chronic arthritis was linked to specific joint issues and less associated with metabolic risks, and CDS was more common in males with greater joint involvement. *

Article Synopsis
  • Coeliac disease (CD) is managed primarily through a strict gluten-free diet (GFD), making it crucial for patients to have a good understanding of the condition and diet.
  • The study systematically reviewed tools for assessing knowledge about CD and GFD, following PRISMA guidelines and examining research from five literature databases.
  • Although 25 studies were analyzed, none of the knowledge assessment tools met all necessary criteria for effectiveness, suggesting a need for better-designed and tested tools that are generalizable across different populations.

Deficits in memory performance have been linked to a wide range of neurological and neuropsychiatric conditions. While many studies have assessed the memory impacts of individual conditions, this study considers a broader perspective by evaluating how memory recall is differentially associated with nine common neuropsychiatric conditions using data drawn from 55 international studies, aggregating 15,883 unique participants aged 15-90. The effects of dementia, mild cognitive impairment, Parkinson's disease, traumatic brain injury, stroke, depression, attention-deficit/hyperactivity disorder (ADHD), schizophrenia, and bipolar disorder on immediate, short-, and long-delay verbal learning and memory (VLM) scores were estimated relative to matched healthy individuals.

  • Corneal cross-linking (CXL) is effective for treating keratoconus in children and those with developmental delays, requiring tailored surgical techniques and careful decision-making.
  • A study at UPMC Children's Hospital analyzed data from 34 patients, revealing that all underwent standard epithelium-off CXL under general anesthesia, with minimal complications and a noted trend towards improved visual acuity post-surgery.
  • The approach included temporary tarsorrhaphy to manage pain effectively, highlighting a safe and timely diagnostic and treatment strategy for these patient groups.

Impaired wound healing due to insufficient cell proliferation and angiogenesis is a significant physical and psychological burden to patients worldwide. Therapeutic delivery of exogenous growth factors (GFs) at high doses for wound repair is non-ideal as GFs have poor stability in proteolytic wound environments. Here, we present a two-stage strategy using bioactive sucralfate-based microneedle (SUC-MN) for delivering interleukin-4 (IL-4) to accelerate wound healing.
