PURPOSE: To evaluate changes to the pelvic floor of primiparous women with different delivery modes, using three-dimensional ultrasound. METHODS: A prospective cross-sectional study on 35 primiparae divided into groups according to the delivery mode: elective cesarean delivery (n=10), vaginal delivery (n=16), and forceps delivery (n=9). Three-dimensional ultrasound on the pelvic floor was performed on the second postpartum day with the patient in a resting position. A convex volumetric transducer (RAB4-8L) was used, in contact with the large labia, with the patient in the gynecological position. Biometric measurements of the urogenital hiatus were taken in the axial plane on images in the rendering mode, in order to assess the area, anteroposterior and transverse diameters, average thickness, and avulsion of the levator ani muscle. Differences between groups were evaluated by determining the mean differences and their respective 95% confidence intervals. The proportions of levator ani muscle avulsion were compared between elective cesarean section and vaginal birth using Fisher's exact test. RESULTS: The mean areas of the urogenital hiatus in the cases of vaginal and forceps deliveries were 17.0 and 20.1 cm², respectively, versus 12.4 cm² in the Control Group (elective cesarean). Avulsion of the levator ani muscle was observed in women who underwent vaginal delivery (3/25), however there was no statistically significant difference between cesarean section and vaginal delivery groups (p=0.5). CONCLUSION: Transperineal three-dimensional ultrasound was useful for assessing the pelvic floor of primiparous women, by allowing pelvic morphological changes to be differentiated according to the delivery mode.

It was to compare pregnant women who experienced recurrent spontaneous abortion (RSA) and those who did not in terms of the prevalence of depressive symptoms and sexual behavior.
A prospective case-control study was carried out. The first group consisted of women with RSA and the second, of primigravidae. The Beck Depression Inventory (BDI), the Female Sexual Function Index (FSFI) and one more questionnaire, developed by the authors themselves, about emotional aspects resulting from sexual intercourse during pregnancy were applied. The Student t-test was used to compare quantitative variables with normal distribution, and categorical variables were compared by the chi-square test or Fisher's exact test. The level of significance was set at p<0.05.
The BDI showed (19.9 versus 10.0%) approximately twice the incidence of depression in the RSA group. Regarding sexual function, the average scores of the FSFI were 21.1 and 16.4 (p<0.05) for the study and control groups, respectively, although no significant difference was observed only in the desire domain (average 3.4±1.3 for the RSA group and 3.7±1.1 for control group) (p=0.1). We observed that, regardless the presence or absence of an RSA history among the pregnant women, the higher the depression score, the lower the sexuality score (r=-0,3).
The RSA pregnant group often experiences twice higher depression and more impaired sexual function. There is an inverse association between depression and sexual function.

To compare the sexual function of healthy adult pregnant women with that of gestational diabetes patients (GDM) in the third trimester. METHODS: This cross-sectional study enrolled two groups of women managed antenatal care clinics. Inclusion criteria were: maternal age .20 years, gestational age at least 28 weeks, being in a heterosexual relationship with the same partner for at least 6 months, and being able to read. We excluded women with a medical recommendation for sexual abstinence due to clinical or obstetric disorders; hypertension controlled through medications; pregnancy resulting from rape; absent or sexually unavailable partner in the last month; hospital admission in the last month; use of vaginal creams in the last 30 days; multiple pregnancy, regular use of alcohol or illicit drugs or use of medications that can interfere with sexual function. Eighty-seven patients fulfilled the selection criteria and were included in the study. The Sexual Quotient . Feminine Version (QS-F) questionnaire was used to assess sexual function. Student's t and X² tests were used to compare differences between groups and p<0.05 was considered significant. RESULTS: The mean gestational age of the participants was 34 weeks. There were no significant differences in the mean QS-F scores between groups (62.5 healthy vs 62.8 GDM women, p=0.9). Approximately half the participants (47 and 47.5% of the healthy and GDM women, respectively, p=0.9) had total scores up to 60, indicative of dysfunction in one of the assessed domains (desire, sexual satisfaction, arousal, orgasm, dyspareunia and vaginismus). CONCLUSIONS: The prevalence of sexual dysfunction was high among women in the third trimester of pregnancy and did not differ significantly between healthy women and women with GDM.

PURPOSE: to evaluate the effect of administration of a stavudine/nelfinavir combination on the rat pregnancy by assessing maternal and concepts weights, as well as the number of implantations, fetuses, placentas, resorptions and maternal and fetal mortality. METHODS: forty adult pregnant Wistar rats of the EPM-1 strain were randomly divided into four groups: control (GCtrl - drug vehicle control, n=10), and three experimental groups, which were treated with an oral solution of stavudine/nelfinavir (ExpI - 1/40 mg/kg b.w., n=10; ExpII - 3/120 mg/kg b.w., n=10; ExpIII - 9/360 mg/kg b.w., n=10) from day 0 to the 20th day of pregnancy. Maternal body weights were determined at the start of the experiment and on the 7th, 14th and the 20th day thereafter. At term (20th day) the rats were anesthetized and, upon laparotomy and hysterotomy, the number of implantations, resorptions, living fetuses, placentae and intrauterine deaths were recorded. The collected fetuses and placentae were weighed and the concepts were examined under a stereomicroscope for possible external malformations. Statistical analysis was performed by analysis of variance (ANOVA) complemented by the Kruskal-Wallis test (p<0.05). RESULTS: there was a progressive and gradual increase in body weight during the course of pregnancy in all groups, which was more evident in the final period, but with no significant difference between groups. The mean number of fetuses, placentas, implantations, and fetal and placental weights showed no significant differences between groups. Also, no resorptions or external malformations were found in the experimental groups. However, between the 8th and 14th days of gestation, there was one case of maternal mortality in each experimental group. CONCLUSIONS: the administration of a stavudine/nelfinavir combination had no deleterious effects on the concepts.

It was to assess the quality of life (QOL) of HIV-infected pregnant women using the HIV/AIDS - Targeted Quality of Life (HAT-QoL) questionnaire.
A descriptive study of 60 pregnant women attended at the Multidisciplinary Nucleus of Infectious Diseases During Pregnancy (NUPAIG) - UNIFESP/EPM and in the referral network of the Municipal Office of São Paulo, conducted from February 2011 to October 2012. Sociodemographic and clinical variables were collected from 60 HIV-infected pregnant women who answered the HAT-QoL questionnaire, which included 34 questions about quality of life.
The average age was 30 years and the average period of HIV infection was 5.7 years. Only 8.3% of patients had a CD4 cell score of ≤200 cells/mm³ and 45% showed undetectable viral load. The average domain scores ranged from 47.5 to 83.7. The domains with the lowest scores were financial concerns and concerns about secrecy. The domains with the highest scores and lower impact on quality of life were concerns about medication and confidence in the professional.
In this initial study with 60 pregnant women, we concluded that the HAT-QOL can contribute to the assessment of quality of life in the population of HIV-infected pregnant women in Brazil.

PURPOSE: to evaluate the effect of the chronic administration of three different doses of Ritonavir in the liver and kidneys of pregnant albino rats and their concepts from a morphological standpoint. METHODS: forty pregnant albino EPM-1 Wistar rats were randomly divided into four groups: Contr (vehicle control), and three experimental groups, Exp20, Exp60, Exp180, which received daily 20, 60 or 180 mg/kg of Ritonavir, respectively. The drug and the vehicle (propyleneglycol) were orally administered by gavage, from the first up to the 20th day of pregnancy. At the last experimental day, all the animals were sacrificed under deep anesthesia, and fragments from the maternal and fetal liver and kidneys were taken and prepared for histological analysis by light microscope. RESULTS: no morphological changes were identified in Exp20 and control group. In the Exp60 group, we found hepatocytes with signs of atrophy and apoptosis (eosinophilic cytoplasm and picnotic nuclei) and marked sinusoid capillary vasodilation (congestion). The proximal convoluted tubules of maternal kidneys and liver showed eosinophilic areas and hyperchromatic nuclei, as well as signs of vasodilation. The maternal kidneys and livers of the Exp180 rats presented more prominent morphological changes than the ones of Exp60. Regarding the fetal organs, no histomorphological abnormalities were observed in all the groups. CONCLUSIONS: our results show that the administration of Ritonavir to pregnant rats, in higher than conventional doses causes morphological changes in the maternal liver and kidneys. On the other hand, the lack of abnormalities in the fetal organs may be due to the protective role of glycoprotein P.

To compare sleep quality of overweight versus normal weight women in the second and third trimesters of pregnancy.
A cross-sectional study involving 223 women with 14 or more weeks of pregnancy, 105 of them overweight (pre-pregnancy body mass index - BMI - ≥25.0 kg/m2) and 118 of normal weight (BMI 18.5-24.9 kg/m2), attending the prenatal care clinic. The Brazilian version of the Pittsburgh Sleep Quality Index (PSQI-BR) questionnaire was used to evaluate sleep quality. The Student t-test and the chi-square test were used to compare differences between groups and a p value <0.05 was considered statistically significant.
Most of the participants (67.7%) were poor sleepers (total score >5); this proportion was significantly higher among overweight (80/105) versus normal weight (67/118) women (76.2 versus 56.8%, p=0,004). During the second trimester, this difference did not reach statistical significance (72.5 versus 53.7%, respectively, p=0.06) but mean total PSQI-BR scores were significantly higher among overweight participants (7.0±3.8 versus 5.5±3.2, p=0.02). In the 2nd trimester, overweight women also had higher scores for sleep latency (1.4±1.0 versus 1.0±0.9, p=0.02) and subjective sleep quality (1.3±0.8 versus 0.8±0.8, p=0.02). In the third trimester, the proportion of women with poor sleep quality was significantly higher in the overweight group, but did not reach statistical significance (79.6 versus 60.8%, p=0.06). During this period, total mean scores were similar for women with and without excess weight (9.4±4.2 versus 8.3±4.6, p=0.2). However, overweight women had higher mean scores for sleep disturbance (2.3±0.7 versus 2.0±0.8, p=0.04).
Overweight women had a poorer sleep quality than normal weight women in the second and third trimesters of pregnancy.
