Prenatal diagnosis of major aortopulmonary collateral arteries (MAPCA) in fetuses with pulmonary atresia with ventricular septal defect and agenesis of ductus arteriosus.

Objective: The aim of this study was to describe the prenatal diagnosis of Major Aortopulmonary Collateral Arteries (MAPCAs), and to present a systematic ultrasound method for evaluating lung vascularity in fetuses with pulmonary atresia with ventricular septal defect (PAVSD) and agenesis of ductus arteriosus (DA).

Method: This retrospective study evaluated fetuses diagnosed with PAVSD with agenesis of DA, for the presence of the MAPCAs anomaly. Fetal pulmonary vasculature was investigated by 2D and 4D Spatio Temporal Image Correlation (STIC) technology using High Definition Color Doppler.

The impact of a daily smartphone-based feedback system among women with gestational diabetes on compliance, glycemic control, satisfaction, and pregnancy outcome: a randomized controlled trial.

Background: Patient compliance and tight glycemic control have been demonstrated to improve outcome in pregnancies complicated by gestational diabetes mellitus. The use of advanced technological tools, including smartphone-based platforms, to improve medical care and outcomes has been demonstrated in various fields of medicine, but only a few small studies were performed with gestational diabetes mellitus patients.

Objective: We aimed to study the impact of introducing a smartphone-based daily feedback and communication platform between gestational diabetes mellitus patients and their physicians, on patient compliance, glycemic control, pregnancy outcome, and patient satisfaction.

Placental pathology and neonatal outcome in small for gestational age pregnancies with and without abnormal umbilical artery Doppler flow.

Objective: To compare neonatal outcome and placental pathology in cases of small for gestational age (SGA) according to umbilical artery (UA) Doppler flow.

Study Design: Pregnancy and placental reports of SGA neonates (birth-weight <10th), born between 2008 and 2017 were compared between cases with normal and abnormal UA Doppler indices. Placental lesions were classified to malperfusion lesions and inflammatory responses.

Natriuria and calciuria levels in preeclampsia: a cross-sectional study.

Context And Objective: Sodium excretion abnormalities in preeclampsia have been studied in relation to several factors. The objective of this study was to compare natriuria (mEq/24 h) and calciuria levels (mg/24 h) in preeclamptic patients.

Design And Setting: An analytical cross-sectional study with a control group was conducted in the obstetric center and the high-risk pregnancy outpatient clinic at a university hospital in southern Brazil, and in a primary healthcare unit in the same city, including pregnant women with mild preeclampsia, severe preeclampsia or chronic hypertension, and women with normal pregnancies (14 patients in each group).

Calciuria and preeclampsia: a case-control study.

Aim: Calciuria has been reported to decrease in preeclampsia. We compared calciuria among groups of normal, hypertensive and preeclamptic pregnant women, and assessed its correlation with the severity of the disease.

Material And Methods: We conducted a case-control study of mild and severe preeclampsia, chronic hypertension, and normal pregnancy, with 14 patients in each group.

Calcium-to-creatinine ratio in pregnancy-induced hypertension.

Objectives: Hypocalciuria has been correlated with preeclampsia. This study compared the calcium-to-creatinine ratio among the groups, and the correlation with the 24-h measurement of this ratio and a diagnosis of preeclampsia.

Study Design: Case-control study including mild and severe preeclampsia, chronic hypertension and normal pregnancy.

Individual serological follow-up of patients with suspected or confirmed abdominal angiostrongyliasis.

Abdominal angiostrongyliasis (AA) is a zoonotic nematode infection caused by Angiostrongylus costaricensis, with widespread occurrence in the Americas. Although the human infection may be highly prevalent, morbidity is low in Southern Brazil. Confirmed diagnosis is based on finding parasitic structures in pathological examination of biopsies or surgical resections.
