Prevalence of musculoskeletal disorders and rheumatic diseases in an Argentinean indigenous Wichi community.

Objective: To estimate the prevalence of musculoskeletal disorders (MSK) and rheumatic diseases in an indigenous Wichi population in Argentina.

Methods: This is a cross-sectional, community-based study using the Community-Oriented Program for the Control of Rheumatic Diseases (COPCORD) methodology in ≥ 18-year-old subjects. Validated surveys were conducted by trained interviewers.

Description of the resources for rheumatology training and speciality certification and recertification requirements in Argentina.

The objective of the study was to analyse resources for rheumatology training, and speciality certification and recertification requirements in Argentina. Information was gathered regarding vacancies, entry requirements, duration and validity of the specialist degree in every residency and postgraduate course in adult rheumatology. The following aspects were analysed: monitoring authority, certification and recertification requirements, and mandatory recertification.

Spanish Validation of the GEPARD Questionnaire for the Detection of Psoriatic Arthritis in Argentinian Patients with Psoriasis.

Background/objective: Psoriatic arthritis (PsA) is preceded by psoriasis in approximately 80% of cases. Dermatologists are pivotal for early detection. It is important to have simple tools that allow the detection of PsA in patients with skin psoriasis.

Reliability of OMERACT ultrasound elementary lesions in gout: results from a multicenter exercise.

The aim of this study was to evaluate the reliability of the outcome measures in rheumatology (OMERACT) definitions for ultrasound (US) elementary lesions in gout through an image reading exercise. Images from patients with gout (static images and videos) were collected. As an initial step, we carried out a image reading exercise within the experts of the Pan-American League of Associations for Rheumatology (PANLAR) US Study Group (n = 16).

Insulin resistance promotes early atherosclerosis via increased proinflammatory proteins and oxidative stress in fructose-fed ApoE-KO mice.

High fructose intake induces an insulin resistance state associated with metabolic syndrome (MS). The effect of vascular inflammation in this model is not completely addressed. The aim of this study was to evaluate vascular remodeling, inflammatory and oxidative stress markers, and atheroma development in high-fructose diet-induced insulin resistance of ApoE-deficient mice (ApoE-KO).

Quercetin and catechin synergistically inhibit angiotensin II-induced redox-dependent signalling pathways in vascular smooth muscle cells from hypertensive rats.

Dietary flavonoids, present in different amount in foods, are associated with the prevention of hypertension, but little is known about the interactions between them. The aim of this study was to explore the effect of quercetin (Q), catechin (C) and the mixture, on Angiotensin II (AngII)-induced redox-dependent signalling pathways and cell behaviour. Mesenteric smooth muscle cells (MesSMC) from spontaneously hypertensive rats (SHR) were incubated with AngII (0.
