First record of xanthochromism in Nasua (Carnivora, Procyonidae) with notes on anomalously colored coatis

Abstract Coatis ( Nasua ) are diurnal, gregarious mesocarnivores widely distributed across the Americas. Chromatic disorders are rarely documented in this genus. Here, we report the first record of xanthochromism in Nasua , based on two individuals of N. nasua observed in Tijuca...

Effect of corn syrup consumption on bone and inflammatory parameters in rats with spontaneous periodontitis

Abstract Background Although added sugar consumption is associated with altered periodontal parameters in humans and alveolar bone loss in rodents, the immunoinflammatory pathways involved and the links between local periodontal and systemic effects are not yet defined. The purpo...

Association between quality-of-life-related indicators and obesity severity categories (Classes I–III): a cross-sectional analysis of the 2019 Brazilian National Health Survey

To investigate associations between quality-of-life-related indicators (QoLRIs) and obesity severity among Brazilian adults and older adults. This cross-sectional study analyzed 2019 Brazilian National Health Survey data from 17,908 individuals with obesity (BMI ≥ 30 kg/m²), incl...

Bioaccumulation and exposure to potentially toxic elements (PTEs) in marine species commercialized for human consumption in the Southern Region of Rio de Janeiro (SE, Brazil)

Sepetiba Bay (Rio de Janeiro, Brazil) is a semi-enclosed coastal system subject to significant anthropogenic pressures resulting from historical industrial activities, port operations, and urban runoff. This study aimed to evaluate the occurrence, organ-specific accumulation, and...

Between Leaves, Prayers, and Healing Hands: A Cross-Regional Scoping Review of Ritual Healers and Plant-Based Community Knowledge

Plant-based healing practices integrate botanical resources, ritual speech, gesture, faith, spiritual mediation, protection, and social recognition within complex community systems of care. This cross-regional scoping review mapped the traceable literature on plant-based knowledg...

Robust topology optimization with non-Gaussian material fields using polygonal finite elements

Abstract We present a computational framework for robust topology optimization that integrates polygonal finite-element discretizations, spatially correlated non-Gaussian material modeling, and non-intrusive polynomial-chaos surrogates. Spatial uncertainty in Young’s modulus is r...

Discontinuous Peripheral Punctate Echogenic Foci in Thyroid Nodules: A New Sonographic Pattern Suggestive of Papillary Carcinoma

Background: Ultrasound risk stratification systems for thyroid nodules worldwide describe different types of echogenic foci, including punctate echogenic foci (microcalcifications), coarse internal calcifications, and peripheral (rim) calcifications (complete or incomplete), with...

Bio‐Inspired Biopolymeric Implantable Platform for Localized and Sustained Drug Delivery in Solid Tumor Treatment

ABSTRACT The development of biocompatible and biodegradable drug delivery systems remains a major challenge in cancer therapy, particularly for the localized and sustained release of poorly soluble, unstable, and highly toxic compounds. 7‐Ethyl‐10‐hydroxycamptothecin (SN‐38), the...

Increased salivary levels of TNF-α and IL-10 in patients with Crohn's disease

Background and objective Salivary cytokines can provide information about oral health and systemic diseases. We aimed to assess the salivary concentration of inflammatory cytokines in outpatients with Crohn's disease (CD) and whether the levels are modified by the presence of per...

Longitudinal Changes in Work-Related Pleasure, Suffering, and Harm Among Healthcare Workers During the COVID-19 Pandemic

Healthcare workers experienced substantial psychosocial challenges during the coronavirus disease 2019 (COVID-19) pandemic, yet longitudinal evidence on changes in work-related pleasure, suffering, and harm remains limited. This study investigated longitudinal changes in psychoso...

Congenital/primary clival meningocele: A systematic review and surgical approach based on a new proposed classification

Skull base meningoceles are extremely rare, most commonly resulting from congenital defects in sphenoid bone fusion. Inadequate embryonic fusion between the posterior sphenoid and the occipital bones may result in a transclival meningocele. Given the absence of a formal classific...

Hybrid training for health and performance: a minimalist framework for sustainable adaptation in advanced recreational practitioners

Abstract Purpose This narrative review aimed to critically examine contemporary training methodologies and propose an evidence-informed framework for integrating strength, hypertrophy, and metabolic conditioning within minimalistic training models. The central research question a...

Semi-analytical solutions to the bi-flux diffusion model using the generalised integral transform technique

Abstract This study presents a high-precision analysis of the Bi-Flux Diffusion Model using the Generalised Integral Transform Technique (GITT). The Bevilacqua–Galeão–Costa (BGC) equation, which characterises anomalous diffusion via a dual-flux framework, is cast in dimensionless...

Low-level laser therapy and conventional treatment for diabetic foot ulcers: a case series

Diabetic foot ulcers (DFUs) are a serious complication of diabetes mellitus and are associated with prolonged healing, increased hospitalization, and risk of amputation. Low-level laser therapy (LLLT), a non-invasive and low-cost modality, has shown potential to accelerate wound...

Associated factors for COVID-19 mortality among children and adolescents in Rio de Janeiro state, 2020–2023

Children and adolescents with COVID-19 typically present milder symptoms of the infection, with fatal outcomes being rare. This study aimed to analyze the main associated factors for mortality in this population group. A cross-sectional study was performed to analyze reported COV...

Perceived learning curve of the nursing team using the da vinci XI surgical system in a Brazilian university hospital

This qualitative exploratory study evaluated 25 nursing team members experienced in Robotic-Assisted Surgery (RAS) at a Brazilian university hospital. Data collection used a validated instrument (CVI = 1.0), and Bardin's thematic analysis identified three competency domains: clin...
