ABSTRACT
RESUMO Objetivo: Avaliar a incidência de embolia pulmonar, seu relacionamento com os níveis de dímero D e outros possíveis fatores associados, além dos efeitos adversos da anticoagulação e meios de contraste. Métodos: Conduziu-se um estudo de coorte retrospectiva em um hospital público chileno. Foram incluídos os pacientes com idade acima de 18 anos com COVID-19, mecanicamente ventilados na unidade de terapia intensiva, admitidos entre março e junho de 2020. Todos os pacientes receberam tromboprofilaxia com heparina, que foi aumentada até uma dose de anticoagulação com níveis de dímero D acima de 3µg/mL. Resultados: Foram acompanhados 127 pacientes, dos quais 73 foram submetidos à angiografia por tomografia computadorizada (média de idade de 54 ± 12 anos; 49 homens). Sessenta e dois dos 73 pacientes (84,9%) receberam anticoagulação total antes da angiografia por tomografia computadorizada. Além disso, 18 dos 73 pacientes tiveram embolia pulmonar (24,7%). Na comparação entre pacientes com e sem embolia pulmonar, não se observaram diferenças significantes em termos de idade, sexo, obesidade, tabagismo, escores de Wells e Genebra revisado, dímero D ou mortalidade. O uso de anticoagulantes foi similar em ambos os grupos. O número de dias desde o início da anticoagulação até a angiografia por tomografia computadorizada foi significantemente menor no grupo com embolia pulmonar (p = 0,002). Três pacientes tiveram lesão renal aguda após o contraste (4,1%), e um paciente teve sangramento importante. Conclusão: Apesar da anticoagulação, um em cada quatro pacientes com COVID-19 submetidos à ventilação mecânica e avaliados com angiografia por tomografia computadorizada apresentou embolia pulmonar. Com uma maior demora para realização da angiografia por tomografia computadorizada após início de anticoagulação empírica, identificou-se um número significantemente menor de embolias
Abstract Objective: To assess pulmonary embolism incidence, its relationship with D-dimer levels and other possible associated factors in addition to anticoagulation and contrast medium adverse effects. Methods: A retrospective observational cohort study at a Chilean public hospital was performed. Intensive care unit mechanically ventilated COVID-19 patients older than 18 years old between March and June 2020 were included. All patients received heparin thromboprophylaxis, which was increased to the anticoagulation dose with D-dimer greater than 3µg/mL. Results: A total of 127 patients were followed up, of whom 73 underwent pulmonary computed tomography angiography (mean age, 54 ± 12 years; 49 men). Sixty-two of the 73 patients (84.9%) received full anticoagulation before computed tomography angiography. In addition, 18 of the 73 patients had pulmonary embolism (24.7%). When comparing patients with and without pulmonary embolism, no significant differences were observed in age, sex, obesity, smoking, Wells and revised Geneva scores, D-dimer or mortality. Anticoagulant use was similar in both groups. Days from the start of anticoagulation until computed tomography angiography were significantly lower in the pulmonary embolism group (p = 0.002). Three patients presented post contrast-acute kidney injury (4.1%), and one patient had major bleeding. Conclusion: Despite anticoagulation, one in four COVID-19 patients connected to mechanical ventilation and evaluated with pulmonary computed tomography angiography had pulmonary embolism. With a longer the delay in performing computed tomography angiography once empirical anticoagulation was started, significantly less pulmonary embolism was identified.

INTRODUCCIÓN Y OBJETIVO: La pandemia por SARS-CoV-2 afecta a las embarazadas con diferentes manifestaciones clínicas; una de ellas es el parto prematuro. El objetivo del presente estudio es caracterizar a las embarazadas con COVID-19 que tuvieron su parto y determinar la razón de aumento de parto prematuro en este grupo en comparación con aquellas que no presentaban la enfermedad. MÉTODOS: Estudio observacional de cohorte retrospectivo donde se incluyeron pacientes embarazadas entre abril y junio del año 2020 en la Maternidad del Hospital San Juan de Dios. Se seleccionaron aquellas que tuvieron su parto y se evaluaron los datos demográficos y médicos, antecedentes obstétricos, información respecto al parto, antecedentes del recién nacido y características de la enfermedad por COVID-19. RESULTADOS: Entre las pacientes COVID-19 un 16.9% tuvo parto prematuro, alcanzando un OR de 1,79 (0,76-3,84 IC 95%) respecto a aquellas sin la enfermedad que, aunque no significativo, evidencia tendencia. Entre las que cursaron con COVID-19 severo todas tuvieron parto prematuro, con un OR significativo (>= 7.84 IC 95%) en comparación con aquellas con cuadro leve o negativas a COVID-19. Un 10.1% de los recién nacidos de madres COVID-19 requirió reanimación neonatal, mientras que en las negativas fue de un 5.5%. CONCLUSIONES: Entre las pacientes COVID-19 se observo una tendencia a aumento del riesgo de parto prematuro respecto a aquellas sin la enfermedad, siendo significativo el aumento del riesgo en aquellas que cursaban con síntomas y aún más significativo si presentaban enfermedad severa.
INTRODUCTION AND OBJECTIVES: The SARS-CoV-2 pandemic has affected pregnant women with different clinical manifestations, one of them premature labor. The objective of this study is to characterize the pregnant patients with COVID-19 who had their delivery and to determine the risk of preterm delivery in this group compared to those who did not have the disease at the Maternity Department in San Juan de Dios Hospital, and determine what the rate of premature delivery is. METHODS: Retrospective observational cohort study where pregnant patients were included between April and June of 2020 at the Maternity Department in San Juan de Dios Hospital. Patients who had their delivery were selected and demographic and medical data, obstetric history, information regarding delivery, newborn history and characteristics of COVID-19 disease were evaluated. RESULTS: Among COVID-19 positives, a 16.9% had premature labor, reaching a nonsignificant OR 1.79 (0.76-3.84 95% CI) compared to those COVID-19 negative. Among those with severe COVID-19, all had preterm birth, with a significant OR (>=7.84 95% CI) compared to those with mild symptoms or COVID-19 negative. 10.1% of newborns of COVID-19 mothers required neonatal resuscitation, while, in the negative ones it was 5.5%. CONCLUSIONS: Among COVID-19 patients, a trend towards increased risk of preterm birth was observed compared to those without the disease, with the increased risk being significant in those with symptoms and even more significant if they had severe disease.

Background: Quality of life and psychological well-being are readily hampered by depression. The changes that students face during college life impact their psychological health and well-being, including the emergence of mental health problems like depression Aim: To determine the relationship between depressive symptoms, sociodemographic parameters and psychological well-being in undergraduate university students. Material and Methods: Five hundred eighty university students of both sexes, from the Metropolitan and IX Regions of Chile answered the Beck Depression Inventory (BDI-IA) and the Ryff's psychological well-being scale. Results: Twenty eight percent of respondents had clinically significant depressive symptoms, and these were more frequent in women. There was an inverse and statistically significant relationship between psychological well-being and depressive symptoms. This fact was especially marked in dimensions of autonomy, positive relationships with others and purpose in life. Conclusions: There is a high frequency of depressive symptoms among these students. We discuss whether psychological well-being and depressive symptomatology represent two extremes within a continuum or they are two independent dimensions that can account for differential causal mechanisms linked to mental health and illness.
