The aim of this study was to determine the content and face validity of the Mackey Childbirth Satisfaction Rating Scale (MCSRS) questionnaire cross-culturally adapted to Brazilian Portuguese.
The MCSRS is a questionnaire with 34 items related to childbirth satisfaction. The forward- and back-translated versions were compared with the original material, and 10 experts analyzed each item according to the following criteria: clarity, semantic equivalence, appropriateness, and cultural relevance. The final version was presented to 10 mothers for face validation to ensure the questionnaire would suit the target population.
The total of 34 items assessed by experts for clarity, semantic equivalence, appropriateness, and relevance showed positive agreement of 0.85, 0.92, 0.97 and 0.97; negative agreement of 0.13, 0.09, 0.04 and 0.04; and total agreement of 0.75; 0.85, 0.94 and 0.94, respectively. Multilevel linear modeling was applied with crossed random effects and with nested random effects for each judge. The intercept of each criterion was as follows: clarity, 0.87; semantic equivalence, 0.92; appropriateness, 0.96; and cultural relevance, 0.96. The overall mean of agreement was 92.8%. The face validity measurement yielded 80% of agreement on the items, all of them clearly understood.
The final version of the Brazilian Portuguese MCSRS questionnaire had face and content validity confirmed. This instrument of evaluation of maternal satisfaction during childbirth was validated to be applied in the Brazilian female population.

PURPOSE: to evaluate the characteristics regarding care of Bolivian pregnant women and their outcomes in Hospital Municipal Vereador José Storopolli. METHODS: a cross-sectional retrospective case-control study comparing two groups of pregnant women from 2003 to 2007. The Study Group included 312 Bolivian pregnant women and the Control Group, 314 Brazilian women. The groups were compared with respect to demographic variables, the presence of maternal complications and perinatal outcomes. Statistical analysis was performed by χ2 test and, when necessary, by applying Yates' correction. RESULTS: compared to Brazilian mothers, a smaller number of Bolivian women received prenatal care (16.4 versus 5.1%, p<0.001) and among those that did, the percentage of those who had less than five visits was higher (50 versus 19.3%, p<0.001). Compared to the Brazilian group, the Bolivian group had fewer unwed mothers (12.1 versus 25.4%, p<0.001) and a lower number of nulliparous women (34.1 versus 43.6%, p=0.017). Congenital syphilis had a higher incidence in the Bolivian group (2.9 versus 0.5%, p<0.05), as well as a higher number of newborns classified as large for gestational age (14.6 versus 5.8%, p <0.001). CONCLUSIONS: the failure to attend prenatal care or its completion with an inadequate number of consultations, and the higher number of cases of congenital syphilis observed among the Bolivian women show the great vulnerability of this ethnic minority group to health problems. Consequently, it is necessary a strategic planning of the sectors responsible for coordinating assistance in our country, in order to reduce this disparity, either through socio-economic improvements or by the implementation of health care tailored to the needs of this group.

PURPOSE: To evaluate, in healthy women in the second trimester of pregnancy, a possible association between sexual function and quality of life, and between sexual function and sexual satisfaction. METHODS: This cross-sectional study involved 51 pregnant women managed at a low-risk antenatal care clinic. Sexual function was evaluated through the Sexual Quotient - Female Version (QS-F) questionnaire. Quality of life and sexual satisfaction were evaluated though the brief version of the World Health Organization Quality of Life questionnaire (WHOQOL-bref). Inclusion criteria were pregnancy between 15-26 weeks, maternal age 20 or more years, at least five years of scholling, in a relationship with a single partner for the last 6 months, having sexual intercourse with vaginal penetration in the last 15 days. We excluded women with a history of sexual violence, previous or current depression, habitual abortion or obstetric complications in the index pregnancy (premature rupture of membranes, preterm labor or hemorrhage). The χ² and Fisher exact tests were used for statistical analyses and p<0.05 was considered significant. RESULTS: Most of the participants (64.8%) obtained "regular to excellent" grades on the QS-F and 58.8% classified their quality of life as "good". As to sexual satisfaction, 35.3 and 15.7% declared that they were "satisfied" and "very satisfied" with their sexual life, respectively. The study detected significant associations between "bad to poor" QS-F grades with a "poor" quality of life (p=0.002), and with "regular to good" and "good to excellent" QS-F grades with "satisfaction" or "high" sexual satisfaction" (p<0.001). CONCLUSIONS: Sexual function is associated with quality of life and with sexual satisfaction in healthy women in the second trimester of pregnancy.

To validate a questionnaire to be applied in order to learn and describe the perceptions of specialists in obstetrics and gynecology about their experience and self-confidence in the emergency care for vaginal delivery.
This was a prospective study for the validation of an instrument that contains statements about emergency obstetrical care: breech delivery (n=23), shoulder dystocia (n=20), postpartum haemorrhage (n=24), forceps delivery (n=32), and vacuum extractor (n=5). Participants gave their opinions on each item by applying the Likert scale (0=strongly disagree, 1=partially disagree, 2=indifferent, 3=partially agree and 4=strongly agree). The questionnaire was applied to 12 specialists in obstetrics and gynecology and it was expected to be found a level of comprehension exceeding 80%. A five-point scale was used to assess the understanding of each question (from 0=did not understand anything to 5=understood perfectly and I have no doubt). A score above 4 was considered to indicate sufficient understanding. The instrument used was specially designed to suit the specific demands. The analysis of internal reliability was done using the Cronbach alpha coefficient. For external validation, we calculated the proportion of items with full understanding for each subscale. For research purposes, the alpha should be greater than 0.7.
Participants had a mean age of 33.3 years, with 5.0 standard deviation (SD), and an average interval time since graduation from medical school of 5.8 years (SD=1.3 years). All were specialists with residency in obstetrics and gynecology. The mean proportion of participants who fully understood the items in each emergency was 97.3% for breech delivery, 96.7% for shoulder dystocia, 99.7% for postpartum hemorrhage, 97.4% for forceps delivery, and 98.3% for the use of a vacuum extractor. The results of Cronbach's alpha for the items in each emergency studied were: 0.85 for breech delivery, with 0.72 lower limit of 95% confidence interval ((%%CI), 0.74 for shoulder dystocia (lower limit of 95%CI=0.51), 0.79 for postpartum hemorrhage (lower limit of 95%CI=0.61), 0.96 for forceps delivery (lower limit of 95%CI=0.92), and 0.90 for the vacuum extractor (lower limit of 95%CI=0.79).
The validated questionnaire is useful for learning and describing the perception of physicians about their experience and self-confidence in emergency care for vaginal births.

PURPOSE: to evaluate the effect of administration of three different doses of the zidovudine/lamivudine/ritonavir combination on the liver and kidneys of pregnant rats and their concepts from a morphological and physiological standpoint. METHODS: 40 pregnant EPM-1 Wistar rats were randomly divided into 4 groups: 1 control (Ctrl: drug vehicle control, n=10) and 3 experimental groups: Exp1x, Exp3x and Exp9x. An oral solution of the zidovudine/lamivudine/ritonavir combination was administered to the experimental groups from the day 0 to day 20 of pregnancy: Exp1x=10/5/20 mg/kg; Exp3x=30/15/60 mg/kg; Exp9x=90/45/180 mg/kg. On the 20th pregnancy day the rats were anesthetized and blood was taken directly from the ventricular chambers for further biochemical determinations: aspartate-(AST) and alanine-(ALT) aminotransferases (Calorimetric method), urea nitrogen (BUN) by an enzymatic-kinetic method, and creatinine by a kinetic-calorimetric method. Maternal and fetal liver and kidney samples were taken, fixed in 10% formaldehyde and processed histologically for paraffin embedding. Five µm-thick fragments of maternal and fetal livers and kidneys were stained with hematoxilyn-eosin, being analyzed by light microscopy. To interpret the results, the well-known pattern of normality for livers and kidneys was considered on the basis of the following structures: hepatocytes, portal structure, hepatic veins, renal corpuscles, renal tubules and loop of Henle. Regarding the fetal livers, we also considered the erythrocytes in their different stages of development as well as the megacariocytes. If there was a change in the established staining pattern for liver and kidney structures, changes in nuclear morphology, rupture of some cytoplasmic organelles, and presence of vascular congestion, this was considered to be due to the drug doses. Results were submitted to analysis of variance (ANOVA) and to the Tukey-Kramer multiple comparisons test (p<0.05). RESULTS: no morphological changes were observed in the maternal livers of the Ctrl, Exp1x and Exp3x groups. In the maternal liver of the Exp9x group, hepatocytes showed signs of atrophy and apoptosis (eosinophilic cytoplasm and pycnotic nuclei) and marked sinusoid capillary vasodilation (congestion) was observed. The maternal kidneys of the Ctrl and Exp1x groups were normal, with renal corpuscles, convoluted tubules and typical loops of Henle. In contrast, the Exp3x and Exp9x groups showed vascular congestion and small glomeruli rich in cells containing hyperchromatic nuclei which were more intense in Exp9x. Regarding the fetal organs, no morphological or physiological changes were observed. A significant increase of AST (305.70±55.80, p<0.05) and creatinine (0.50±0.09, p<0.05) was observed in group Exp9x. CONCLUSIONS: our results show that the administration of the zidovudine, lamivudine and ritonavir combination to pregnant rats at high doses caused morphological and physiological changes in the maternal liver and kidneys. On the other hand, there were no changes in fetal organs.

To describe the experience of a distance education course on sexual issues during pregnancy and after birth for residents.
This prospective educational intervention study was conducted by investigators from the Universidade Federal de São Paulo, Brazil, between April and September 2014. The participants were 219 physicians (residents from the 1st to the 6th years). The duration of the course was of 24 hours (10 video lectures and online chats). At baseline, the participants answered questions about their training, attitude and experience regarding sexual issues during pregnancy and after birth; before and after the course, they answered questions to assess their knowledge about the topic; at the end of the course, they answered questions on the quality of the course. The Student t-test was used to compare the before and after scores of the knowledge tests; values of p < 0.05 were considered statistically significant.
A total of 143 residents concluded the course; most were in their 1st (27.2%) or 3rd (29.4%) years of residency. There was a significant increase in themean scores of the questionnaires that assessed the knowledge of the topic: 4.4 (1.6) versus 6.0 (1.3; maximum score: 10), before and after the course respectively (p < 0.0001). Most of the participants (74.1%) declared that the quality of the course as a whole reached their expectations, and 81.1% would recommend the course to a friend.
The online Sexology course for Obstetrics and Gynecology residents increased their knowledge about the sexual issues during pregnancy and after birth, and fulfilled the participants’ expectations. The experience described heremay serve as a model for other sexuality courses targeting similar audiences.
