    Abstract

    Objective:

    To compare access and suitability of antenatal care between years 2020 and 2022 among postpartum individuals at a Hospital in Florianopolis, and evaluate factors associated with antenatal suitability.

    Methods:

    Observational, cross-sectional, and quantitative study carried out in 2022. Collected data were compared with the database of a previous similar study carried out in the same setting in 2020. Data were extracted from medical records and prenatal booklets, in addition to a face-to-face questionnaire. Adequacy was measured using the Carvalho and Novaes index and health access was qualitatively evaluated. Socio-demographic and antenatal variables were analyzed. A statistical significance level of 0.05 was considered. Open-ended questions were categorized for analysis.

    Results:

    395 postpartum individuals were included. Antenatal care was adequate for 48.6% in 2020 and 69.1% in 2022. Among the barriers to access, 56% reported difficulty in scheduling appointments and/or exams and 23% complained of reduced healthcare staff due to strikes, COVID-19, among others. Adequate antenatal care was associated with being pregnant in 2022, being referred to high-risk units (PNAR), and not reporting difficulties in access. Also, it was associated with twice the chance of investigation for gestational diabetes (GDM) and syphilis.

    Conclusion:

    The 2022 post-vaccination period showed higher antenatal adequacy. The main difficulty for postpartum individuals was scheduling appointments and/or exams. Having antenatal care in 2022, no reports of difficulty in access, and follow-up at a high-risk unit were associated with antenatal adequacy.

    Abstract

    Gestational diabetes mellitus (GDM)is an entity with evolving conceptual nuances that deserve full consideration. Gestational diabetes leads to complications and adverse effects on the mother's and infants' health during and after pregnancy. Women also have a higher prevalence of urinary incontinence (UI) related to the hyperglycemic status during pregnancy. However, the exact pathophysiological mechanism is still uncertain. We conducted a narrative review discussing the impact of GDM on the women's pelvic floor and performed image assessment using three-dimensional ultrasonography to evaluate and predict future UI.

    PURPOSE: To measure fetal renal volume in normoglycemic and hyperglycemic pregnancies. METHODS: A longitudinal prospective study was conducted and included 92 hyperglycemic and 339 normoglycemic pregnant women attended at the prenatal service of a hospital from Rio de Janeiro State. Ultrasound examinations were performed to estimate gestational age at baseline and the kidney volume was estimated using the prolate ellipsoid volume equation. RESULTS: Fetal kidney volume growth between normoglycemic and hyperglycemic pregnancies are significantly different. The fetal kidney volume growth in pregnancy is positively correlated with gestational age explained by these predictor equations, by group: normal renal volume = exp (6.186+0.09×gestational week); hyperglycemic renal volume = exp (6.978+0.071×gestational week) and an excessive growth pattern for hyperglycemic pregnancies may be established according to gestational age. CONCLUSION: This is important for early detection of abnormalities in pregnancy, particularly in diabetic mothers.

    PURPOSES: To evaluate the hemodynamic patterns of the ophthalmic artery by Doppler analysis in women with gestational diabetes mellitus (GDM), comparing them to normal pregnant women. METHODS: A prospective case-control study that analyzed the ophthalmic artery Doppler indices in two groups: one consisting of 40 women diagnosed with GDM and the other of 40 normal pregnant women. Included were pregnant women with GDM criteria of the American Diabetes Association - 2012, with 27 weeks of pregnancy to term, and excluded were women with hypertension, use of vasoactive drugs on or previous diagnosis of diabetes. Doppler analysis was performed in one eye with a 10 MHz linear transducer and the Sonoace 8000 Live Medison® equipment . The following variables were analyzed: pulsatility index (PI), resistance index (RI), peak velocity ratio (PVR), peak systolic velocity (PSV) and end diastolic velocity (EDV). To analyze the normality of the samples we used the Lillefors test, and to compare means and medians we used the Student's t-test and Mann-Whitney test according to data normality, with the level of significance set at 95%. RESULTS: The median and mean values with standard deviation of the variables of the ophthalmic artery Dopplervelocimetry group GDM and normal pregnant women were: IP=1.7±0.6 and 1.6±0.4 (p=0.7); IR=0.7 and 0.7 (p=0.9); RPV=0.5±0.1 and 0.5±0.1 (p=0.1), PSV=33.6 and 31.9 cm/sec (p=0.7); VDF=6.3 and 7.9 cm/sec (p=0.4). There was no significant difference in the means and medians of these variables between the two groups of pregnant women. CONCLUSIONS: The ophthalmic artery hemodynamic patterns, analyzed by means of a Doppler technique remained unchanged in the group of pregnant women with GDM compared to the group of normal pregnant women, suggesting that the time of exposure to the disease during pregnancy was too short to cause significant vascular disorders in the central territory.

    Fetal and placental effects of insulin therapy on pregnancy of diabetic rats were studied. Alloxan was administered intravenously at the dose of 42 mg/kg of body weight. Five experimental groups were formed: control (G1, n=12), non-treated rats with moderate diabetes (G2, n=10), insulin-treated rats with moderate diabetes (G3, n=11),non-treated rats with severe diabetes (G4, n=12) and insulin-treated rats with severe diabetes (G5, n=10). Six hundred and thirty-four newborn rats and placentas wereprocured. The perinatal result of insulin therapy was directly related to the quality of glycemia control. Thus, inadequate control of moderate diabetes produced levels of moderate hyperglycemia, did not interfere with the newborn rats' body weight and decreased the proportion of LGA newborn rats. Adequate control of severe diabetes brought the newborn rat glycemia to normal levels, increased the newborn rats' body weight and decreased the proportion of SGA newborn rats. Adequate insulin therapy for severe diabetes diminished the weight of the placentas, but did not change the placental index.

    The objective was to evaluate the accuracy of the foam stability test, lecithin/sphingomyelin (LS) ratio, presence of phosphatidylglycerol (PG) and lung profile (L/S ratio > 1.7 and PG present simultaneously) in 121 consecutive high-risk gestations at the São Paulo Hospital from January 1990 to January 1995. Delivery occurred within 3 days of fetal lung maturation testing. This is a prospective study in which the sensitivity, specificity, positive (PPV) and negative predictive value (NPV) of all the tests were determined. Neonatal respiratory outcome and amniocentesis results were stratified by gestational age for comparison. The distribution of the studied population according to maternal pathology was diabetes mellitus (48), hypertensive disorders (41), Rh isoimmunization (14) and miscellaneous (18). Respiratory distress (RD) was present in 33 infants (27.2%), mainly in the diabetic group. There was no false negative using lung profile (all patients) and foam stability tests among hypertensive pregnancies (specificity 100%), but there were about 20% to 50% false positives in the other tests. Overall, all four tests had a low PPV: 23% for foam test, 51% for L/S ratio, 63% for PG, 61% for lung profile, and high NPV: 92% for foam test, 88% for L/S ratio, 89% for PG and 100% for lung profile. All tests had less accuracy in the diabetic pregnant women. This study shows that the presence of PG and L/S ratio > 1.7 in the amniotic fluid of high-risk pregnancies confirms maturity with a very low risk to develop RD and that the foam stability test was useful as a first-line test to predict the absence of surfactant-deficient respiratory distress syndrome, particularly in hypertensive pregnant women.

    Purpose: to present the perinatal outcomes resulting from the use of a protocol for assistance to diabetic pregnant women used at the Center for Integral Assistance to Women's Health (CAISM), of the University of Campinas. Methods: ninety diabetic pregnant women, who were assisted at the institution with this protocol, were compared with two control grups: the first consisted of 180 pregnant women with equal number of gestations and same age (control A) and the second consisted of 180 randomly selected pregnant women (control B). The study variables were route of delivery, indication for cesarean section, gestational age, Apgar score at first and fifth minute, weight, adequacy of weight for gestational age and perinatal morbidity and mortality. For the statistical analysis Student's t-test and the chi2 test were used. Results: there was a higher incidence of cesarean sections, prematures and large to gestational age (LGA) babies among diabetic women, as well as higher occurrence of neonatal morbidity such as hypoglycemia, hypocalcemia, hyperbilirubinemia, respiratory distress and neonatal depression. The incidence of low Apgar score and perinatal mortality was significantly higher than in the randomly selected group, but the same as in the group matched regarding age and number of pregnancies. Conclusions: although this protocol intends to obtain a perfect metabolic control among diabetic pregnant women, the perinatal outcomes are still unfavorable in comparison to nondiabetic pregnant women.

    OBJECTIVE: to assess the action of antiretroviral drugs on glycid metabolism and on the pancreas of pregnant Wistar rats. METHODS: adult pregnant Wistar rats weighing 200-230g were used. Azidothymidine, lamivudine and nelfinavir were administered to the animals at doses 10 times higher than those administered to pregnant women. The animals were divided into seven groups of 10 animals, including a control group. The animals were sacrificed on the 21st day of pregnancy and glycemia, insulinemia, glucagonemia, free fatty acids (FFA) and hepatic glycogen were measured. Direct counts of the number of immunohistochemically labeled insulin- and glucagon-producing cells were used to determine pancreatic damage. Data were analyzed statistically by the Student's t-test comparing each treated group with the control group. RESULTS: increased serum glucagon (control group: 88.2 pg/ml; treated groups: 99.7-120.7 pg/ml) and reduced insulin (control group: 6.2 muIU/ml; treated groups: 2.1-2.7 muIU/ml) were observed in all groups treated with antiretroviral drugs after 21 days of pregnancy. There was no significant difference between the experimental groups and the control in glycemia, plasma FFA or hepatic glycogen. Also, there was no significant difference in number of insulin- and glucagon-producing cells between the treated groups and the control. CONCLUSION: treatment of noninfected rats with antiretroviral drugs during pregnancy altered maternal glycid metabolism causing insulin decrease and glucagon elevation, with normal glycemia and unchanged number of pancreatic cells.
