Introduction: Acute respiratory distress syndrome (ARDS) in the endothelium causes vasoconstriction, adhesion of inflammatory cells and development of pulmonary edema, pulmonary hypertension and thrombosis. This endothelial damage lowers the production of nitric oxide (NO) and increases the expression of endothelin-1 (ET-1). The aim of this study was to evaluate the effect of pretreatment with L-arginine in OA-induced ALI. Material and methods: Hemodynamic, gasometric, microscopic, immunohistochemical and plasma concentration of ET-1 and ET-1 y ETB were analyzed in an experimental model of AO-induced ARDS. The dogs were divided into three study groups: I (n = 6), control; II (n = 6), OA-induced ARDS at an IV dose of 0.09 mL/kg, untreated, and III (n = 6), pretreatment with L-arginine at 0.125 g/min/IV in 250 mL of 0.09% saline and OA-induced ARDS. Results: The hemodynamic, blood gas and gravimetric findings revealed that groups II and III developed ARDS. Intrapulmonary shunt increased in groups II and III (p < 0.05, ANDEVA Dunnett). PaO 2 /FiO 2 decreased in groups II and III with a significant difference with group I (p < 0.05, ANDEVA MR Dunnett). in an experimental model of AO-induced acute SIRA attenuated hypoxic pulmonary vasoconstriction (HPV) leading to deterioration in intrapulmonary shunting. However, the edema and inflammatory infiltrate in the tissue decreased, therefore, in this model you can only consider a potential attenuating effect on lung inflammation during the acute phase by L-arginine.","PeriodicalId":246416,"journal":{"name":"NCT Neumología y Cirugía de Tórax","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133068313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Introducción: Los costos relacionados con el insomnio asociado a trastornos del estado de ánimo siguen siendo poco estudiados pese a su alta prevalencia e incidencia mundial asociada a la pandemia COVID-19. Objetivos: Determinar los costos directos e indirectos del insomnio asociado a trastorno anímico. Material y métodos: Estudio observacional prospectivo, incluyó pacientes entre 18 y 65 años, diagnosticados con insomnio crónico asociado a trastornos del estado de ánimo (depresión y/o ansiedad) entre febrero de 2019 y febrero de 2020. Los datos sobre utilización de recursos sanitarios se recopilaron mediante la revisión de los registros médicos. Se diseñó un cuestionario para evaluar los costos no médicos directos e indirectos con datos sociodemográficos, transporte, bebidas energéticas, gastos en actividad física, modificaciones del hogar, compra de accesorios especiales, jornada laboral y salario. El ausentismo y el presentismo laboral se determinaron utilizando el Cuestionario de Salud y Desempeño de la OMS. Se realizó un análisis de sensibilidad determinista. Resultados: El costo total estimado por paciente durante el primer año de tratamiento fue de 3,503.49 USD. La pérdida de productividad laboral fue el costo que más contribuyó a la carga económica (64.5%), seguido de los costos médicos directos (27.6%), mientras que los costos no médicos directos contribuyeron menos (7.9%). Se calculó una carga económica anual de poco más de 290 millones de dólares para los pacientes tratados en el sistema de salud privado similar a la CTSUNAM. El análisis de sensibilidad mostró que la prevalencia de insomnio crónico asociado a trastorno del estado de ánimo, la pérdida de productividad laboral y el porcentaje de personas que buscan atención en un sistema privado fueron los parámetros con mayor impacto sobre la estimación de la carga económica total. Conclusiones: Los costos del insomnio asociado a trastorno anímico son altos.

In addition, measuring fraction of exhaled nitric oxide can help prevent exacerbations because it allows increases in infl ammatory activity to be detected and treated immediately. The purpose of this document is to review practical aspects of the fraction of exhaled nitric oxide-measuring technique using a portable device, and to provide clinical physicians with useful instruments that will aid in achieving correct interpretations of results.

Introduction: The binomial term overlap asthma/COPD is a subset of patients with persistence and airflow limitation that presents clinical features of both asthma and COPD. Initial studies have shown that omalizumab may be useful in patients with ACOS, it has been shown to improve symptoms, reduce exacerbations and hospitalization, as well as improve lung function parameters and reduced steroid requirement in these patients. Objective: To describe the effect of omalizumab in 5 patients with a diagnosis of overlying asthma/COPD syndrome (OAC) and administration of omalizumab. We describe the experience of our center and the benefits that the treatment has given to our patients. Material and methods: We present 5 cases of patients with a diagnosis of overlap asthma/COPD syndrome after application of omalizumab (300 mg SC each month) significantly improved their symptoms in ACT (asthma control test) and respiratory function tests, mainly in spirometry. This 5 patients gave their consent to present cases. Results: The 5 patients with OAC received Omalizumab have experienced improvement of symptoms in ACT (asthma control test) and improvement of 10 to 20 and 25 points. Omalizumab was well tolerated without complications. 100% of patients showed improvement in symptoms (ACT), higher percentage are women as described in the literature, patients tolerated the treatment without presenting major adverse effects. Conclusion: The cases described offer initial evidence of our medical practice on the benefits of omalizumab in patients with clinically improving overlying asthma/COPD syndrome. Omalizumab demonstrates good tolerance without presenting adverse effects. These benefits have allowed the patient a better quality of life and radically reduce their morbidity. words:","PeriodicalId":246416,"journal":{"name":"NCT Neumología y Cirugía de Tórax","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124231930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
