Summary
Psoriatic arthritis (PsA) is a complex joint disease impacting quality of life. Early diagnosis and treatment, including biologics, improve outcomes for PsA patients.
Area of Science:
- Rheumatology and Immunology
Background:
- Psoriatic arthritis (PsA) is a systemic, polymorphic joint disease with variable presentation and clinical course.
- Outcomes are influenced by comorbidities like diabetes, hypertension, and dyslipidemia.
- Early diagnosis is crucial, especially with subtle skin manifestations.
Purpose of the Study:
- Discuss new concepts in immunogenetics, pathophysiology, and clinical/therapeutic aspects of PsA.
- Emphasize factors affecting quality of life and life expectancy.
- Highlight new treatment guidelines and the role of GRAPPA.
Main Methods:
- Extensive literature review (PubMed, Lilacs).
- Analysis of clinical experience.
Main Results:
- Progressive erosive disease affects up to 50% of patients.
- Anti-TNF biologics enable inflammation control, particularly in enthesitis and axial PsA.
- GRAPPA facilitates collaborative research between rheumatologists and dermatologists.
Conclusions:
- Delayed diagnosis and treatment negatively impact PsA prognosis.
- Biologics have significantly improved inflammatory control in PsA.
- Multidisciplinary collaboration, as promoted by GRAPPA, is vital for advancing PsA management.

Chronic Inflammation: Introduction
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
Contemporary Psychology
Psychology explores human behavior and mental processes through various lenses, each offering unique insights. This overview examines key subfields, including biopsychology, evolutionary, developmental, personality, and social psychology, highlighting their approaches and contributions to understanding complex human behaviors.

Connective Tissue Cell Types
Connective tissue develops from the mesoderm of a developing embryo and consists of cells, fibers, and ground substance: a gel-like material containing large complexes of carbohydrates and proteins. Connective tissue was first identified as a separate tissue family in the 18th century, and Johannes Peter Muller coined the term connective tissue.
Fat cells (adipocytes), smooth muscle cells (myoblasts), and bone cells (osteoblasts) are some connective tissue cell types. Some immune system cells...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
T Cell Types and Functions
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

Peripheral Artery Disease I: Introduction
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...
