Corporate social responsibility and employee motivation: intrinsic and extrinsic pathways in Vietnamese SMEs

Purpose This study aims to conceptualize corporate social responsibility (CSR) as a potentially need-supportive organizational context. This study examines how CSR-related autonomy, competence and relatedness are associated with employees’ intrinsic and extrinsic motivation and h...

Design Feasibility and Identification of Local Covariance Paths

ABSTRACT Overlapping local covariance estimates can share the same population information. We characterize the information in their retained moments, distinguishing full‐line Gaussian systems from compact empirical designs. Smooth diffusion constructions give different covariance...

Spatial Differentiation of Population Aging in a Rapidly Aging Latin American Region: Evidence from the Maule Region, Chile, 1992–2024

Population aging is a defining demographic transformation in Latin America, yet its subnational spatial dynamics remain insufficiently understood. We examined population aging in the Maule Region of Chile from 1992 to 2024 using official census data at provincial and commune leve...

Mechanisms of Exercise Training in Ameliorating Cognitive Function in Patients With Depression: A Narrative Review of Molecular Targets and Clinical Prescriptions

ABSTRACT Depression is frequently accompanied by core cognitive impairments, notably in executive function and memory. Although the ameliorative effects of exercise training have been widely corroborated, the evidence regarding its underlying mechanisms remains fragmented. To pro...

Alveolar bone loss and dentoalveolar remodelling in pre-Columbian human remains from northern Chile

Alveolar bone loss in archaeological human remains is a composite skeletal outcome influenced by biological ageing, occlusal function, compensatory eruption, antemortem tooth loss, and inflammatory destruction. Accordingly, cementoenamel junction–alveolar crest (CEJ–AC) distance...

Maternal Influenza Infection During Pregnancy and Neuropsychiatric Disorders in Offspring

Importance Evidence on maternal influenza infection during pregnancy and offspring neuropsychiatric risk remains inconsistent and limited by methodologic concerns. Objective To evaluate the association of maternal influenza infection during pregnancy and offspring neuropsychiatri...

The Human Labial Superficial Musculoaponeurotic System (SMAS): Anatomy, Imaging, and Biomechanical and Sensory Implications—A Narrative Review

The superficial musculoaponeurotic system (SMAS) is a fundamental concept in facial anatomy and surgery, but its organization within the human lips remains incompletely defined. This narrative review critically reassesses the anatomical evidence for a labial SMAS and its regional...

Planar Tetracoordinate Hydrogen Stabilized Within Alkali Metal–Halogen Frameworks

A D 4h screening of the 25 H©M 4 X 4 − combinations (M = Li–Cs; X = F–At), followed by unbiased global‐minimum searches on the nine vibrationally stable candidates, reveals eight previously unreported planar tetracoordinate hydrogen (ptH) global minima adopting D 4h symmetry, bri...

Cardiometabolic multimorbidity phenotypes and their associations with functional and cognitive outcomes in older Chilean adults: findings from the Chilean national health survey

Abstract Background Multimorbidity is highly prevalent among older adults and is associated with functional decline, disability, cognitive impairment, and increased healthcare burden. However, traditional disease-count approaches may fail to capture the heterogeneity of multimorb...

Landmark-defined two-dimensional lung configuration in women with osteogenesis imperfecta type III: an exploratory geometric morphometric pilot study

Osteogenesis imperfecta (OI) type III is a rare disorder in which severe thoracic deformity may alter pulmonary anatomy. This exploratory pilot study assessed whether the relative two-dimensional configuration of four reproducible pulmonary landmarks differs between adult women w...

Ebola-virus outbreaks are teleconnected with macroclimatic oscillations

Ebola viruses’ ecology is known to be affected by climate, which is globally monitored using macroclimatic oscillation indices. We tested whether any of 26 macroclimatic oscillation indices were teleconnected with Ebola virus disease (EBOD) outbreaks. We compiled an updated datab...

Prevalence of neuropsychiatric and seizure disorders in neurofibromatosis type 1: a systematic review and meta-analysis

Neurofibromatosis type 1 (NF1) is associated with intellectual disability (ID), autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD), emotional and seizure disorders. However, published prevalence estimates vary widely. The aim of this meta-analysis was...

Diagnostic Accuracy of Artificial Intelligence for Dental Caries Detection Across Clinical Imaging Modalities: A Systematic Review and Descriptive Synthesis

Background/Objectives: Published estimates of artificial-intelligence (AI) accuracy for dental caries differ in imaging modality, lesion threshold, observational unit, reference standard, and validation design. We mapped the clinical composition and credibility of this evidence a...

Are Selenium Status and Inflammation Linked to Cardiometabolic Risk Factors in Inborn Errors of Immunity?

Background/Objective: Patients with Inborn Errors of Immunity (IEI) are at increased cardiometabolic risk due to inflammation, immune dysfunction, and oxidative stress. Given selenium’s essential role in antioxidant defense, this study evaluated plasma selenium concentration in i...

Topology-Driven Compression and Energy Absorption of PLA-Lattice-Reinforced Mortar

The design of cellular architectures based on topology offers a promising strategy for tailoring the mechanical performance of cementitious composites without altering the matrix composition. However, the influence of the topological transition from re-entrant auxetic structures...

Effects of Curcumin Supplementation on Inflammatory Biomarkers in Adults with Type 2 Diabetes Mellitus: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Background/Objectives: Chronic low-grade inflammation contributes to the pathophysiology of type 2 diabetes mellitus (T2DM). This systematic review and meta-analysis evaluated randomized evidence on the effects of oral curcumin or curcuminoid supplementation on circulating inflam...

Evidence-Based Quality Assurance in Initial Teacher Education and Educational Sustainability

Quality assurance in Initial Teacher Education (ITE) has evolved from compliance-oriented approaches toward more comprehensive frameworks emphasizing continuous improvement, evidence-informed decision-making, and educational sustainability. Nevertheless, across Latin America, per...

Adherence to the Mediterranean Diet and Academic Performance in University Students: A Systematic Review and Meta-Analysis

Background/Objectives: Adherence to the Mediterranean diet (MedDiet) has been associated with numerous health benefits, yet it is often suboptimal among university students. Its relationship with academic performance (AP), an outcome with potential long-term implications, has not...

Women's Perceptions of Sexual Function During the Postpartum Period: Systematic Review of Qualitative Evidence

INTRODUCTION: Sexuality is a multifaceted aspect of life influenced by several dimensions, including biology, psychology, socioeconomics, and spirituality. Postpartum sexual health remains an understudied and relevant area for women. This systematic review of qualitative studies...

Beyond bactericidal surfaces: interfacial selectivity as a design principle for implant biomaterials

Within seconds of placement, an adsorbed conditioning film replaces the implant's manufactured substrate and becomes the true interface host cells and microorganisms encounter. Conventional strategies engineered to kill or suppress bacteria therefore act on an interface neither p...
