Impact of exposure of emergency patients with acute heart failure to atmospheric Saharan desert dust
OBJECTIVES: To explore whether episodes of exposure to atmospheric Saharan dust is a risk factor for hospitalization in patients with acute heart failure (AHF) attended in a hospital emergency department (ED). MATERIAL AND METHODS: TSingle-center retrospective study of patients with AHF. The cohort was analyzed in 2 groups: ED patients hospitalized with AHF and patients discharged home from the ED. Air pollution on the 5 days leading to ED admission for AHF was recorded as the average concentration of breathable particulate matter with an aerodynamic diameter of no more than 10 µm (PM10) in the following ranges: fine PM (diameter less than 2.5 µm) or coarse PM (diameters between 2.5 and 10 µm). High Saharan dust pollution exposure was defined by mean daily PM10 concentrations between 50 and 200 µg/m3. Multivariable analysis was used to estimate risk for AHF in relation to PM10 exposure in the 5 days before the ED visit. RESULTS: A total of 1097 patients with AHF were treated in the ED; 318 of them (29%) were hospitalized and 779 (71%) were discharged home. Hospitalized patients were older, had more concomitant illnesses, and more episodes of exposure to Saharan dust (P < .0001). Multivariable analysis confirmed the association between Saharan dust exposure and hospital admission in these patients (odds ratio, 2.36; 95% CI, 1.21-4.58; P = .01). CONCLUSION: In the absence of prospective studies, the results of this series suggest that exposure to high levels of Saharan dust (PM10 concentrations between 50 and 200 µg/m3) may be a precipitating factor for hospitalization in AHF episodes.OBJETIVO: Evaluar si la exposición a episodios de polvo sahariano predice los ingresos hospitalarios de los pacientes con insuficiencia cardiaca aguda (ICA) atendidos en un servicio de urgencias hospitalario (SUH). METODO: Estudio unicéntrico, de cohorte retrospectiva, de pacientes con ICA atendidos en un SUH. La población de estudio se dividió en 2 grupos: pacientes ingresados por ICA y pacientes con ICA dados de alta directa a domicilio desde el SUH. Se analizaron las concentraciones medias de material partículado (PMx) (respirables, diámetro aerodinámico, da< 10 µm), PM2,5 (finas, da <2,5 µm) y PM2,5-10 (gruesas, da 2,5-10 µm) desde el día de la llegada al SUH hasta 5 días previos. Se definió exposición intensa al polvo sahariano cuando las concentraciones medias diarias de PM10 estaban entre 50 y 200 µg/m3. La relación para estimar el riesgo de ingresar por ICA en función de la exposición de PMx durante los 5 días previos a su llegada a urgencias se analizó mediante análisis multivariable. RESULTADOS: Se incluyeron 1.097 pacientes con ICA, ingresaron 318 pacientes (29%), 779 (71%) se dieron de alta. Los pacientes ingresados por ICA tenían mayor edad, elevada comorbilidad y mayor proporción de pacientes expuestos a episodios intensos de polvo sahariano (p < 0,0001). En el análisis multivariable la exposición a episodios de polvo sahariano intensos se relacionó con el ingreso hospitalario en los pacientes con ICA (OR = 2,36; IC 95% 1,21-4,58; p = 0,01). CONCLUSIONES: En ausencia de estudios prospectivos, los resultados obtenidos de la serie analizada sugieren que la presencia de concentraciones elevadas de polvo sahariano (PM10: 50-200 µg/m3) puede constituir un factor precipitante de ingreso por ICA.Los autores declaran la no existencia de financiación en

Design of an algorithm for the diagnostic approach of patients with joint pain
Background
Rheumatic diseases are a reason for frequent consultation with primary care doctors. Unfortunately, there is a high percentage of misdiagnosis.
Objective
To design an algorithm to be used by primary care physicians to improve the diagnostic approach of the patient with joint pain, and thus improve the diagnostic capacity in four rheumatic diseases.
Methods
Based on the information obtained from a literature review, we identified the main symptoms, signs, and paraclinical tests related to the diagnosis of rheumatoid arthritis, spondyloarthritis with peripheral involvement, systemic lupus erythematosus with joint involvement, and osteoarthritis. We conducted 3 consultations with a group of expert rheumatologists, using the Delphi technique, to design a diagnostic algorithm that has as a starting point “joint pain” as a common symptom for the four diseases.
Results
Thirty-nine rheumatologists from 18 countries of Ibero-America participated in the Delphi exercise. In the first consultation, we presented 94 items to the experts (35 symptoms, 31 signs, and 28 paraclinical tests) candidates to be part of the algorithm; 74 items (25 symptoms, 27 signs, and 22 paraclinical tests) were chosen. In the second consultation, the decision nodes of the algorithm were chosen, and in the third, its final structure was defined. The Delphi exercise lasted 8 months; 100% of the experts participated in the three consultations.
Conclusion
We present an algorithm designed through an international consensus of experts, in which Delphi methodology was used, to support primary care physicians in the clinical approach to patients with joint pain
Long-term safety of COVID vaccination in individuals with idiopathic inflammatory myopathies: results from the COVAD study
Limited evidence on long-term COVID-19 vaccine safety in patients with idiopathic inflammatory myopathies (IIMs) continues to contribute to vaccine hesitancy. We studied delayed-onset vaccine adverse events (AEs) in patients with IIMs, other systemic autoimmune and inflammatory disorders (SAIDs), and healthy controls (HCs), using data from the second COVID-19 Vaccination in Autoimmune Diseases (COVAD) study. A validated self-reporting e-survey was circulated by the COVAD study group (157 collaborators, 106 countries) from Feb-June 2022. We collected data on demographics, comorbidities, IIM/SAID details, COVID-19 history, and vaccination details. Delayed-onset (> 7 day) AEs were analyzed using regression models. A total of 15165 respondents undertook the survey, of whom 8759 responses from vaccinated individuals [median age 46 (35-58) years, 74.4% females, 45.4% Caucasians] were analyzed. Of these, 1390 (15.9%) had IIMs, 50.6% other SAIDs, and 33.5% HCs. Among IIMs, 16.3% and 10.2% patients reported minor and major AEs, respectively, and 0.72% (n = 10) required hospitalization. Notably patients with IIMs experienced fewer minor AEs than other SAIDs, though rashes were expectedly more than HCs [OR 4.0; 95% CI 2.2-7.0, p < 0.001]. IIM patients with active disease, overlap myositis, autoimmune comorbidities, and ChadOx1 nCOV-19 (Oxford/AstraZeneca) recipients reported AEs more often, while those with inclusion body myositis, and BNT162b2 (Pfizer) recipients reported fewer AEs. Vaccination is reassuringly safe in individuals with IIMs, with AEs, hospitalizations comparable to SAIDs, and largely limited to those with autoimmune multimorbidity and active disease. These observations may inform guidelines to identify high-risk patients warranting close monitoring in the post-vaccination period
