ABSTRACT

The aim of this study was to assess the shear wave velocity by LUS elastography (SWE2D) for the evaluation of superficial lung stiffness after COVID-19 pneumonia, according to "fibrosis-like" signs found by Computed Tomography (CT), considering the respiratory function. Seventy-nine adults participated in the study 42 to 353 days from symptom onset. Paired evaluations (SWE2D and CT) were performed along with the assessment of arterial blood gases and spirometry, three times with 100 days in between. During the follow-up and within each evaluation, the SWE2D velocity changed over time (MANOVA, p < 0.05) according to the extent of "fibrosis-like" CT signs by lung lobe (ANOVA, p < 0.05). The variability of the SWE2D velocity was consistently related to the first-second forced expiratory volume and the forced vital capacity (MANCOVA, p < 0.05), which changed over time with no change in blood gases. Covariance was also observed with age and patients' body mass index, the time from symptom onset until hospital admission, and the history of diabetes in those who required intensive care during the acute phase (MANCOVA, p < 0.05). After COVID-19 pneumonia, SWE2D velocity can be related to the extent and regression of "fibrotic-like" involvement of the lung lobes, and it could be a complementary tool in the follow-up after COVID-19 pneumonia.

ABSTRACT

Introduccin. La hipertension arterial (HTA) constituye un problema de salud mundial y su riesgo depende de los Organos que sea capaz de dañar. La hipertrofia ventricular izquierda (HVI) define a un grupo de enfermos con alto riesgo de presentar complicaciones y, entre ellos, los adolescentes son tambien vulnerables. El objetivo de esta investigacion fue detectar precozmente la presencia de HVI en adolescentes hipertensos para orientar el tratamiento y reducir las complicaciones. Material y metodo. Se llevó a cabo un estudio de intervencion, cuasiexperimental, longitudinal, prospectivo en 572 adolescentes hipertensos. Se realizo ecocardiograma al inicio de la investigacion y se ajusto el tratamiento medico para comparar al año los resultados. Resultados. Predominó el sexo masculino (73,3 por ciento) y el color de la piel negra (63,6 por ciento). El mayor porcentaje de pacientes (53,0 por ciento) presentaba HTA moderada. Solo el 5,9 por ciento de ellos aplicaba correctamente las medidas higienico-dieteticas y las estrategias farmacologicas estaban subutilizadas. Al inicio del estudio, el 73,6 por ciento de los pacientes llevaban un tratamiento irregular y no lograban controlar su tension arterial. Al año habi­amos logrado controlar al 92 por ciento de los enfermos, se redujo la HVI y se mejoro la disfuncion diastólica ...(AU)
