Abstract
The aim of this longitudinal study was to investigate the value of uterine artery Doppler sonography during the second and third trimesters in the prediction of adverse pregnancy outcome in low-risk women.From July 2011 to August 2012, a total of 205 singleton pregnant women presenting at our antenatal clinic were enrolled in this prospective study and were assessed for baseline demographic and obstetric data. They underwent ultrasound evaluation at the time of second and third trimesters, both included Doppler assessment of bilateral uterine arteries to determine the values of the pulsatility index (PI) and resistance index (RI) and presence of early diastolic notch. The endpoint of this study was assessing the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of Doppler ultrasonography of the uterine artery, for the prediction of adverse pregnancy outcomes including preeclampsia, stillbirth, placental abruption and preterm labor.The mean age of cases was 26.4±5.11. The uterine artery PI and RI values for both second (PI: 1.1±0.42 versus 1.53±0.59, p=0.002; RI: 0.55±0.09 versus 0.72±0.13, p=0.000 respectively) and third-trimester (PI: 0.77±0.31 versus 1.09±0.46, p=0.000; RI: 0.46±0.10 versus 0.60±0.14, p=0.010 respectively) evaluations were significantly higher in patients with adverse pregnancy outcome than in normal women. Combination of PI and RI >95th percentile and presence of bilateral notch in second trimester get sensitivity and specificity of 36.1 and 97% respectively, while these measures were 57.5 and 98.2% in third trimester.According to our study, it seems that uterine artery Doppler may be a valuable tool for the prediction of a variety of adverse outcomes in second and third trimesters.
Highlights
To evaluate the frequency of sleep disorders, such as obstructive sleep apnea, restless leg syndrome and insomnia in overweight/obese postmenopausal women seen in a climacteric sleep disorders clinic
Frequência dos distúrbios de sono em mulheres na pós-menopausa com sobrepeso/obesidade for sleep apnea by the Berlin Questionnaire
When the groups were compared, a linear association was identified between body mass index (BMI) and the AHI average, and a relationship between high BMI and use of drugs for thyroid treatment was found
Summary
OBJETIVOS: Avaliar a frequência dos distúrbios do sono, como apneia obstrutiva do sono, síndrome das pernas inquietas e insônia, em pacientes na pós-menopausa com sobrepeso/obesidade no ambulatório de distúrbios do sono no climatério. 85,2% apresentou relação cintura/ quadril igual ou superior a 0,8; metade apresentou escore igual ou superior a 9 na Escala de Epworth; 68% apresentou distúrbio do sono de acordo com o índice de Pittsburgh e 68% dos casos foram classificados como de alto risco para apneia do sono pelo Questionário Berlin. Comparando os grupos, houve associação linear média entre IMC e IAH e relação entre IMC elevado e uso de medicações para distúrbios da tireoide. CONCLUSÃO: Foi observada alta prevalência de distúrbio respiratório do sono, sono fragmentado e insônia de início, bem como maior incidência de distúrbios da tireoide no grupo com IMC mais elevado
