To evaluate the follicular development of female Wistar rats with obesity induced by the cafeteria diet, submitted to the administration of losartan (LOS), an antagonist of the AT1 receptor of Angiotensin II.
At weaning (21 days of age), female Wistar rats were randomly divided, into two groups: control (CTL) that received standard chow and cafeteria (CAF) that received a cafeteria diet, a highly palatable and highly caloric diet. At 70 days of age, at the beginning of the reproductive age, animals of the CAF group were subdivided into two groups (n=15/group): CAF, that received water, and CAF+LOS, that received LOS for 30 days. The CTL group also received water by gavage. At 100 days of age, the animals were euthanized and body weight (BW) as well as the retroperitoneal, perigonadal and subcutaneous fat weights were analyzed. The right ovaries were isolated for counting the number of primary, secondary, antral and mature follicles. Plasma levels of FSH, LH, prolactin and progesterone hormones were analyzed. The results were expressed as mean±standard error of the mean. Data were analyzed statistically by one-way ANOVA followed by the Newman-Keuls post-test (p<0.05).
BW and fat weight, as well as the number of antral follicles, were higher in the CAF group compared to the CTL group. However, FSH and LH levels were lower in CAF animals compared to CTL animals. LOS administration attenuated the reduction of FSH and LH levels. Progesterone and PRL levels were similar among groups.
LOS could improve follicular development in obese females and could be used as an adjunctive drug in the treatment of infertility associated with obesity.

To estimate the likelihood of axillary lymph node involvement for patients with early-stage breast cancer, based on a variety of clinical and pathological factors.
A retrospective analysis was done in hospital databases from 1999 to 2007. Two hundred thirty-nine patients were diagnosed with early-stage breast cancer. Predictive factors, such as patient age, tumor size, lymphovascular invasion, histological grade and immunohistochemical subtype were analyzed to identify variables that may be associated with axillary lymph node metastasis.
Patients with tumors that are negative for estrogen receptor, progesterone receptor, and HER2 had approximately a 90% lower chance of developing lymph node metastasis than those with luminal A tumors (e.g., ER+ and/or PR+ and HER2-) - Odds Ratio: 0.11; 95% confidence interval: 0.01-0.88; p=0.01. Furthermore, the risk for lymph node metastasis of luminal A tumors seemed to decrease as patient age increased, and it was directly correlated with tumor size.
The molecular classification of early-stage breast cancer using immunohistochemistry may help predicting the probability of developing axillary lymph node metastasis. Further studies are needed to optimize predictions for nodal involvement, with the aim of aiding the decision-making process for breast cancer treatment.

To identify the predominant species and the role of sexual partners in the maintenance of recurrent vulvovaginitis by Candida spp.
A prospective study of 830 patients aged 18 to 65 years with yeast vaginitis was performed between August 2007 and March 2012. Patients with diabetes mellitus, AIDS or taking corticosteroids, antibiotics or hormone therapy and immunosuppressed patients, patients using vaginal douches, spermicides or intrauterine devices were excluded from the study. Candida species were identified by phenotypic and genotypic methods. The chi-square test was used to correlate the presence of Candida spp. in male partners with the recurrence of vaginitis.
The fungal agent was isolated from a total of 40 women, 24 with recurrent vaginitis and from 15 of their sexual partners, 10 of whom were asymptomatic while 5 were symptomatic. There was agreement of the species found in the couple in 100% of recurrences. C. albicans (62.4 and 60%), C. glabrata (29.1 and 33.3%) and C. guilliermondii species were identified. Candida tropicalis (4.1%) was isolated from only one patient. Candida albicans was isolated from the remaining 16 women who had uncomplicated vaginitis. C. glabrata was isolated from only two of the asymptomatic partners.
There was a predominance of C. albicans and symptomatic or asymptomatic partners can play an important role as a reservoir and source of transmission of yeast, especially in cases of recurrent vulvovaginitis.

To compare body attitudes of pregnant women in various body mass index categories, during different gestational periods and under gestational risk conditions, as well as to analyze the association of the study variables with the body attitudes of pregnant women.
We included 386 pregnant women in all gestational periods, aged 18 to 46 years (mean 29.32±6.04 years ), who attended prenatal care in the public and private sectors of a city in Southeastern Brazil, excluding women with incomplete data. The instruments for assessment were "Body Attitudes Questionnaire", "Critério de Classificação Econômica Brasil", and a sociodemographic questionnaire. In addition, anthropometric and obstetric data were collected. Descriptive, comparative, and correlational statistical analyses were performed.
The body attitudes of pregnant women were similar in all pregnancy trimesters (F=0.39; p=0.9). Negative body attitudes increased gradually among low weight (108.2±12.5), appropriate weight (116.2±16.0), overweight (125.1±14.3), and obese (132.9±16.4) groups, and among pregnancy women with normal (120.0±17.1) and high-risk pregnancies (124.9±16.7). The sociodemographic, economic, and obstetric variables did not influence the variance of body attitudes. The body mass index explained 11.3% of the variance of body attitudes in pregnant women.
Nutritional status and risk conditions showed an association with negative body image and should therefore be evaluated in pregnant women for a better maternal and child health.

To determine the eating behavior of pregnant women assisted by primary health care and to compare it with women at childbearing age in Brazilian capitals.
A cross-sectional study conducted on 256 pregnant women in the second trimester of gestation, selected by drawing lots from those assisted by primary health care units of a municipality in the state of São Paulo in 2009/2010. Eating habits were investigated via a questionnaire adapted from the VIGITEL system, consisting of questions about eating habits in general and the frequency and consumption characteristics of food groups/specific foods. For tis comparison, we used the indicators reported by the VIGITEL system for women at childbearing age in Brazilian capitals in 2010. The analyses involved the presentation of frequency distribution and descriptive statistics with comparisons according to the age group.
Most patients had breakfast every day (86.7%) and 45.7% habitually exchanged a main meal for a snack once or twice a week. A daily consumption of fruit, raw salad and vegetables was not reported by 48.8%, 41.8% and 55.1% of the women, respectively. Fish was reported to never or almost never be consumed by 64.4% of the pregnant women. At least once a week, 69.9% of them reported the consumption of soda, and 86.4% of wafers/cookies. The comparison between the pregnant women and women at childbearing age in capitals showed a close similar prevalence of overweight, and no difference in the regular consumption of fruit and vegetables. Meat containing excess of fat and whole milk were more consumed by pregnant women, with differences reported in all the age groups analyzed. On the other hand, the pregnant women reported a less regular intake of soft drinks.
The actions that need to be performed in prenatal care are various and very important, promoting the consumption of specific foods and providing guidelines about eating behavior, while reinforcing healthy eating habits already present.

To describe the prevalence of malformations found in fetuses with trisomy of chromosomes 13, 18 and 21 by identifying the most frequent within each condition.
A retrospective cross-sectional study with the analysis of trisomy cases of chromosomes 13, 18 and 21 diagnosed through fetal karyotype obtained by amniocentesis/cordocentesis, between October 1994 and May 2014, at a Teaching Hospital in Brazil Southern Region. Malformations identified through morphological ultrasonography were described and, subsequently, confirmed in newborn examinations and/or fetal autopsy. The results were analyzed using Fisher's test and analysis of variance (ANOVA), with a 5% level of significance (p=0.05).
Sixty-nine cases of trisomy were diagnosed among 840 exams; nine were excluded due to outcome outside Hospital de Clínicas de Porto Alegre or incomplete records, remaining 60 cases (nine cases of chromosome 13 trisomy, 26 of chromosome 18, and 25 of chromosome 21). In all three groups, heart disease occurred in most cases; the ventricular septal defect was more prevalent and occurred in 66.7% of the trisomy 13 group. Gastrointestinal abnormalities were more prevalent in the trisomy 18 group, especially omphalocele (38.5%; p<0.01). Genitourinary anomalies were more significantly frequent in the trisomy 13 group (pyelectasis, 55.6% - p<0.01; ambiguous genitalia, 33.3% - p=0.01). Central nervous system defects were identified in all cases of trisomy 13. Facial cracks were significantly more prevalent among fetuses with trisomy 13 (66.7%; p<0.01). Hand and feet malformations significantly differed among the trisomy groups. Hand defects occurred in 50% of trisomy 18 cases, and in 44.4% of all trisomy 13 cases (p<0.01); congenital clubfoot was more common in the trisomy 18 group, being detected in 46.2% of fetuses (p<0.01). The abnormalities were found in 50.9, 27.3 and 21.7% of trisomy 18, 13 and 21 cases respectively.
Many fetal malformations identified at ultrasound are suggestive of trisomy and represent an important tool for etiologic diagnosis and prenatal and pre-conception genetic counseling.

We report here a case of gestational trophoblastic neoplasia after spontaneous normalization of human chorionic gonadotropin in a patient with a partial hydatidiform mole. This is the second occurrence of this event to be reported and the first one with proven immunohistochemical evidence. Besides showing the treatment for this pregnancy complication, this case report discusses the possibility of reducing the duration of post-molar follow-up, as well as strategies for early recognition of gestational trophoblastic neoplasia after spontaneous remission of molar pregnancy.
