Abstract Recent studies have reported the occurrence of thrombotic phenomena or coagulopathy in patients with COVID-19. There are divergent positions regarding the prevention, diagnosis, and treatment of these phenomena, and current clinical practice is based solely on deductions by extension from retrospective studies, case series, observational studies, and international guidelines developed prior to the pandemic. In this context, the aim was to generate a group of recommendations on the prevention, diagnosis and management of thrombotic complications associated with COVID-19. Methods: A rapid guidance was carried out applying the GRADE Evidence to Decision (EtD) frameworks and an iterative participation system, with statistical and qualitative analysis. Results: 31 clinical recommendations were generated focused on: a) Coagulation tests in symptomatic adults with suspected infection or confirmed SARS CoV-2 infection; b) Thromboprophylaxis in adults diagnosed with COVID-19 (Risk scales, thromboprophylaxis for outpatient, in-hospital management, and duration of thromboprophylaxis after discharge from hospitalization), c) Diagnosis and treatment of thrombotic complications, and d) Management of people with previous indication of anticoagulant agents. Conclusions: Recommendations of this consensus guide clinical decision-making regarding the prevention, diagnosis, and treatment of thrombotic phenomena in patients with COVID-19, and represent an agreement that will help decrease the dispersion in clinical practices according to the challenge imposed by the pandemic.

Tomographic and functional findings in severe COPD: comparison between the wood smoke-related and smoking-related disease.

OBJECTIVE: Wood smoke exposure is a risk factor for COPD. For a given degree of airway obstruction, the reduction in DLCO is smaller in individuals with wood smoke-related COPD than in those with smoking-related COPD, suggesting that there is less emphysema in the former. The objective of this study was to compare HRCT findings between women with wood smoke-related COPD and women with smoking-related COPD. METHODS: Twenty-two women with severe COPD (FEV1/FVC ratio < 70% and FEV1 < 50%) were divided into two groups: those with wood smoke-related COPD (n = 12) and those with smoking-related COPD (n = 10). The two groups were compared regarding emphysema scores and airway involvement (as determined by HRCT); and functional abnormalities-spirometry results, DLCO, alveolar volume (VA), the DLCO/VA ratio, lung volumes, and specific airway resistance (sRaw). RESULTS: There were no significant differences between the two groups in terms of FEV1, sRaw, or lung hyperinflation. Decreases in DLCO and in the DLCO/VA ratio were greater in the smoking-related COPD group subjects, who also had higher emphysema scores, in comparison with the wood smoke-related COPD group subjects. In the wood smoke-related COPD group, HRCT scans showed no significant emphysema, the main findings being peribronchial thickening, bronchial dilation, and subsegmental atelectasis. CONCLUSIONS: Female patients with severe wood smoke-related COPD do not appear to develop emphysema, although they do show severe airway involvement. The reduction in DLCO and VA, with a normal DLCO/VA ratio, is probably due to severe bronchial obstruction and incomplete mixing of inspired gas during the determination of single-breath DLCO.

Diferencias tomográficas y funcionales entre la EPOC severa relacionada con humo de leña y con cigarrillo: comparison between the wood smoke-related and smoking-related disease / Tomographic and functional findings in severe COPD

OBJETIVO: La exposición a humo de leña es factor de riesgo para EPOC. A diferencia de la EPOC por cigarrillo (EPOC-C), para un mismo nivel de obstrucción, en la EPOC por leña (EPOC-L), la DLCO está menos disminuida, sugiriendo menos enfisema. Por tanto, el objetivo de este estudio fue comparar los hallazgos en la TCAR en mujeres con EPOC-L y con EPOC- C. MÉTODOS: Veintidós mujeres con EPOC severa (VEF1/CVF < 70% y VEF1 < 50%) fueron divididas en dos grupos: las expuestas a leña (EPOC-L; n = 12) y las expuestas a cigarrillo (EPOC-C; n = 10). Se compararon los dos grupos con respecto al puntaje de enfisema y el compromiso de la vía aérea en la TCAR, las anormalidades funcionales en la espirometría, la DLCO, los volúmenes pulmonares y la resistencia específica de la vía aérea (sRaw). RESULTADOS: Los dos grupos tuvieron VEF1, sRaw e hiperinflación pulmonar similares. En el grupo EPOC-C, hubo mayor disminución de la DLCO y de la DLCO/VA y mayor puntaje de enfisema. En el grupo EPOC-L, no encontramos enfisema significativo en la TCAR. Los hallazgos principales fueron engrosamiento peribronquial, dilataciones bronquiales y atelectasias subsegmentarias. CONCLUSIONES: En pacientes con EPOC-L severa no hay enfisema en la TCAR. El hallazgo más importante es el compromiso severo de la vía aérea. La disminución de la DLCO y del VA con DLCO/VA normal es probablemente determinada por la obstrucción bronquial severa y la mezcla incompleta del gas inspirado en la maniobra de la respiración única de la prueba de difusión.

The implant of Cardioverter-Defi brillator has changes the pronostic in the primary and secondary prevention in the patients with suden death. There are a lot of evidence that supports that the therapies of the CDI (antitachycardia and shocks) have impact on the morbimortality of the patients with Implantable Cardioverter-Defi brillators, besides the effect proarritmogenic. Objective: It is for determining which is the incidence of appropriate and inappropriate therapies in our population of patients with Implantable Cardioverter-Defi brillators for primary and secondary prevention of sudden death. Materials and Methods: we describe a case series of patients with cardioverter-Defi brillator as the primary and secondary prevention of sudden death in a clinic of fourth level of complexity. Results: the incidence of therapy of the Implantable Cardioverter-Defi brillators after implant in patients with primary and secondary prevention of sudden death to the fi rst year of follow-up was 44%. The incidence of apropiate therapy of the Implantable Cardioverter-Defi brillators after implant in patients with primary prevention of sudden death to the fi rst year of follow-up was the 26.3%.

The incidence of apropiate therapy of the Implantable Cardioverter-Defi brillators after implant in patients with secondary prevention of sudden death to the fi rst year of follow-up was the 53%. The half of the patients with Implantable Cardioverter-Defi brillators afterimpant for primary prevention or secondary had apropiate therapies during the fi rst year of follow-up. 36% of the patients presented inappropriate therapies during the year of follow-up after fi rst implat of the Implantable Cardioverter-Defi brillators. Conclusions: the therapies after to the implant of cardioverter-Defi brillator were near to the half of the patients, being more frecuent in the secundary prevention. These events may be present in the different pathologies, and to be apropiate and inapropiate. The complications of procedure may be acutes and chronics.
