Alopecia Induced by Poly-L-Lactic Acid Injection.

Cosmetic procedures carry inherent risks of adverse events. Though rarely reported, transient and permanent alopecia are potential complications of these procedures. We report the case of a 35-year-old woman who developed pain and patches of nonscarring alopecia with erythema and edema following aesthetic application of poly-L-lactic acid (PLLA) on the face and along the frontal hairline.

Immunogenicity and Safety According to Immunosuppressive Drugs and Different COVID-19 Vaccine Platforms in Immune-Mediated Disease: Data from SAFER Cohort.

Background/objectives: The effectiveness of COVID-19 vaccine in patients with immune-mediated inflammatory diseases (IMID) depends on the underlying disease, immunosuppression degree and the vaccine regimens. We evaluate the safety and immunogenicity of different COVID-19 vaccine schedules.

Methods: The SAFER study: "Safety and effectiveness of the COVID-19 Vaccine in Rheumatic Disease", is a Brazilian multicentric prospective observational phase IV study in the real-life.

Creativity and Body: Living Metaphors in the Context of People Undergoing Heart Transplantation.

This article explores the embodied dimension of authoring life trajectories for individuals who have undergone heart transplantation. Confronting the radical otherness of existential finitude can create a rich context for examining the relationships between authorship, corporeality, and creative processes. By integrating Merleau-Ponty's phenomenology of the body with Susanne Langer's theory of affective semiosis and presentational signs, this work aims to foster a productive dialogue between these perspectives, grounded in Semiotic Cultural Psychology, which meta-theoretically synthesizes a diverse range of knowledge on the transformative interaction between individuals and culture.

Thermally Activated Delayed Fluorescence in B,N-Substituted Tetracene Derivatives: A Theoretical Pathway to Enhanced OLED Materials.

Polycyclic aromatic hydrocarbons (PAHs) exhibit intriguing characteristics that position them as promising candidates for advancements in organic semiconductor technologies. Notably, tetracene finds substantial utility in Electronics due to its application in organic light-emitting diodes (OLEDs) and organic field-effect transistors (OFETs). The strategic introduction of an isoelectronic boron-nitrogen (B,N) pair to replace a carbon-carbon pair in acenes introduces changes in the electronic structure, allowing for the controlled modulation of diradical characteristics.

Low Bone Turnover, Mineralization Impairment, and Cortical Alterations in Patients with Axial Spondyloarthritis: A Histomorphometric Study.

Patients with radiographic axial spondyloarthritis (r-axSpA) experience a higher prevalence of fragility fractures, though the pathophysiology of osteoporosis associated with this disease remains poorly understood. The objective of this study was to evaluate the histomorphometric data in r-axSpA patients. Male r-axSpA patients up to 55 years old were enrolled in this cross-sectional study.
