    Introduction: pulmonary artery flow metric in healthy fetuses can be a predictive study of lung maturity, which leads to an impact on the decrease in perinatal mortality.Objective: to establish the ratio of pulmonary artery acceleration time to ejection time (AT/ET) as an indicator of fetal lung maturity in pregnant women from 26 to 40 weeks of gestation (WG), users of the “Hospital Especializado Fundación Humanitaria Pablo Jaramillo Crespo”, period 2017.Methods: A validity study of diagnostic tests was carried out. Pulmonary artery flow metric was evaluated by Doppler ultrasound in 300 healthy fetuses of pregnant women between 15 to 45 years old. Surveys were used to collect data. Sensitivity (S), specificity (E), positive predictive value (PPV) and negative predictive value (NPV) were used to determine validity.Results: the value of the TA / TE index of the pulmonary artery was 0.216 for pregnant women between 26-28 WG; of 0.253 between 29-31 WG; 0.279 between 32-34 WG; 0.315 for pregnant women between 35-37 WG and 0.349 between 38-40 WG. The 37 WG at the cut-off point was 0.320; the ROC area was 0.98 with a S: 95.2%, E: 97.2%. The PPV 93.0% and NPV 98.1%.Conclusions: the AT/ET ratio of pulmonary artery showed correlation with gestational age. An AT/ET ratio of 0.320, as a cut-off point, predicts fetal lung maturity

    Intraepithelial cervical lesions in indigenous in Ecuador
    (2019) Salazar Torres, Zoila Katherine; Murillo Bacilio, Magdali Del rocio; Castro Reyes, Boris Santiago; Cardenas Heredia, Freddy Rosendo; Sanchez Salazar, Gustavo Mauricio
    The aim of this research was to determine the prevalence of cervical intraepithelial lesions in indigenous women of Ecuador 2017. A descriptive study was performed. Population was formed by 2489 indigenous women aged 15 to 64 years old, of which 396 users were chosen by spontaneous demand. Frequency values and percentages were taken from qualitative variables, while mean and standard deviation were taken from quantitative variables. Prevalence of intraepithelial lesions was 13,8%. Average age was 31 years old. Uncertain importance's squamous atypical cells were higher in 30-to-39-year-old group (46,7%). Non-specific atypical glandular cells were observed in 66,7% of 30-to-39-year-old group. Low-grade intraepithelial lesions were majorly found in 20-to-29-year-old group (43,8%). High-grade intraepithelial lesions were also seen in 20-to-29-year-old group. Conclusions were: prevalence of intraepithelial lesions in indigenous women of Ecuador was higher than 10% of reported in other studies, and more frequent in those aged 20 and 39 years old.
