To evaluate the perception of health professionals involved in the labor process and theassistanceto normal delivery, comparing two hospitals in the cityof Goiânia, Brazil, regarding the perception of theseprofessionals when they are performing the routines and practices recommended by the World Health Organization (WHO).
This is an analytical comparative study with a quantitative approach, performed in two public hospitals in the city of Goiânia, in the state of Goiás, Brazil. The study included 86 professionals working in assistance to immediate labor in two hospitals. A questionnaire containing 40 questions was applied. The questionnaire related to the Program for the Humanization of Prenatal and Childbirth Care (PHPN, in the Portuguese acronym) of the Brazilian Ministry of Health, the presence of a companion, and the procedures performed. For the data analysis, we used the chisquare and Fisher’s exact tests.
Most of the professionals claimed to know about the PHPN proposed by Brazilian Ministry of Health in the two hospitals. With regard to good practices, most professionals said that they are performed in maternity ward 2, while on maternity 1, although many of them are present, there are still many unnecessary interventions.
When comparing the two maternity hospitals, maternity 2, which was created as a routine humanization model, manages to better adhere to the WHO recommendations. In maternity 1, there was a series of interventions considered by the WHO as ineffective, or used in an inappropriate manner.

In 2013, it was estimated that 289,000 maternal deaths occurred worldwide. The maternal mortality ratio has decreased in many countries in the past decades, due to early identification and treatment of obstetric complications, despite the dissimilarities observed in diverse locations and populations. Black women, for instance, have always been more susceptible to the occurrence of maternal mortality and severe morbidity. Therefore, the objective of this study is to assess skin color as a predictive factor for maternal near miss (MNM) in a sample of Brazilian women interviewed in the Brazilian National Demographic and Health Survey (DHS) of 2006.
A secondary analysis of the DHS database, a population-based crosssectional nationally representative study was conducted. This database is of public domain. The risk of maternal complications according to ethnic group and the associated sociodemographic characteristics were evaluated. For the data analysis, the odds ratios and respective 95% confidence intervals were calculated.
In the sample interviewed, 59% of women were black or brown (mixed-race). Approximately 23% of women had some complication, and 2% of these women had at least one MNM pragmatic criterion. The MNM rate was 31 per 1,000 live births, and its occurrence was not statistically different among the ethnic groups. The only factors identified that were considered to be associated with the occurrence of MNM were maternal age above 40 and women not currently attending school, but only among white women.
The 2006 DHS results did not show a higher occurrence of maternal complications, and specifically of MNM associated with black/brown skin color.

To evaluate the effect of mesenchymal stem cells (MSCs) on fertility in experimental retrocervical endometriosis.
A total of 27 New Zealand rabbits were divided into three groups: endometriosis, in which endometrial implants were created; mesenchymal, in which MSCs were applied in addition to the creation of endometrial implants; and control, the group without endometriosis. Fisher’s exact test was performed to compare the dichotomous qualitative variables among the groups. The quantitative variables were compared by the nonparametric Mann-Whitney and Kruskal-Wallis tests. The MannWhitney test was used for post-hoc multiple comparison with Boniferroni correction.
Regarding the beginning of the fertile period, the three groups had medians of 14±12.7, 40±5, and 33±8.9 days respectively (p = 0.005). With regard to fertility (number of pregnancies), the endometriosis and control groups showed a rate of 77.78%, whereas the mesenchymal group showed a rate of 11.20% (p = 0.015). No differences in Keenan’s histological classification were observed among the groups (p = 0.730). With regard to the macroscopic appearance of the lesions, the mesenchymal group showed the most pelvic adhesions.
The use of MSCs in endometriosis negatively contributed to fertility, suggesting the role of these cells in the development of this disease.

This study analyzed the effectiveness of the thyroid-stimulating hormone (TSH) as a predictor of insulin resistance (IR) and its association with the clinical and metabolic parameters of women with polycystic ovary syndrome (PCOS) without overt hypothyroidism.
A cross-sectional study was performed. Women with PCOS and without overt hypothyroidism (n = 168) were included.
Receiver operating characteristic (ROC) curve was used to determine the cut-off point for TSH that would maximize sensitivity and specificity for a diagnosis of IR using homeostatic model assessment of insulin resistance (HOMA-IR)≥ 2.71. Clinical and metabolic parameters were compared as a function of the TSH cut-off limit and the presence of IR.
Thyroid-stimulating hormone ≥ 2.77 mIU/L was associated with a diagnosis of IR, with sensitivity of 47.9% and specificity of 65.3%. There were no differences in clinical, hormonal or metabolic parameters between TSH < 2.77 and TSH of 2.77 - 10 mIU/L.
In women with PCOS without overt hypothyroidism, TSH ≥2.77 mIU/L is associated with IR; however, with poor sensibility, showing TSH to be a poor predictor of IR in this population. No clinical or metabolic alterations were found that would justify a change in clinical management. Thus, the IR should be investigated in all women with PCOS irrespective of TSH level.

Preoperatively identification of malignancy potential of a postmenopausal adnexal masses is important.
To evaluate the effectiveness of the Risk of Malignancy Index-2 in presumably benign adnexal masses in postmenopausal women.
Retrospective, observational study.
119 women with postmenopausal adnexal masses with a preliminary diagnosis of benign tumors according to the Risk of Malignancy Index-2 were included. Age, duration of menopause, ultrasonographic findings, and serum CA-125 levels were recorded preoperatively. The definitive diagnosis was based on postoperative histopathological examination.
Of 119 adnexal mass, 10 were malignant and 109 were benign. There was no statistically significant difference with regard to age and tumor size between the groups. The two significant ultrasonographic parameter between groups were the presence of solid area in the mass and bilaterality. Moreover, if the cut off point for serum CA-125 was adjusted to 14.75 IU/mL according to ROC curve, a sensitivity value of 80% and a specificity value of 72% could be achieved to discriminate benign and malign cysts.
In the differential diagnosis of benign and malignant adnexal masses in postmenopausal women, the presence of a solid component, bilaterallity based on ultrasonography and high CA-125 values may be used as discriminative criteria. There is no direct relation between the size of the adnexal mass and malignancy potential. Therefore, in the malignancy indexes of postmenopausal women, we recommend lower cut-off values of CA-125 to increase the sensitivity of preoperative evaluation tests without having a great impact on negative predictive values.

From the discovery of the Zika virus (ZIKV) in 1947 in Uganda (Africa), until its arrival in South America, it was not known that it would affect human reproductive life so severely. Today, damagetothe central nervous system is known to be multiple, and microcephaly is considered the tip of the iceberg. Microcephaly actually represents the epilogue of this infection’s devastating process on the central nervous system of embryos and fetuses. As a result of central nervous system aggression by the ZIKV, this infection brings the possibility of arthrogryposis, dysphagia, deafness and visual impairment. All of these changes of varying severity directly or indirectly compromise the future life of these children, and are already considered a congenital syndrome linked to the ZIKV. Diagnosis is one of the main difficulties in the approach of this infection. Considering the clinical part, it has manifestations common to infections by the dengue virus and the chikungunya fever, varying only in subjective intensities. The most frequent clinical variables are rash, febrile state, non-purulent conjunctivitis and arthralgia, among others. In terms of laboratory resources, there are also limitations to the subsidiary diagnosis. Molecular biology tests are based on polymerase chain reaction (PCR)with reverse transcriptase (RT) action, since the ZIKV is a ribonucleic acid (RNA) virus. The RT-PCR shows serum or plasma positivity for a short period of time, no more than five days after the onset of the signs and symptoms. The ZIKVurine test is positive for a longer period, up to 14 days. There are still no reliable techniques for the serological diagnosis of this infection. If there are no complications (meningoencephalitis or Guillain-Barré syndrome), further examination is unnecessary to assess systemic impairment. However, evidence is needed to rule out other infections that also cause rashes, such as dengue, chikungunya, syphilis, toxoplasmosis, cytomegalovirus, rubella, and herpes. There is no specific antiviral therapy against ZIKV, and the therapeutic approach to infected pregnant women is limited to the use of antipyretics and analgesics. Anti-inflammatory drugs should be avoided until the diagnosis of dengue is discarded. There is no need to modify the schedule of prenatal visits for pregnant women infected by ZIKV, but it is necessary to guarantee three ultrasound examinations during pregnancy for low-risk pregnancies, and monthly for pregnant women with confirmed ZIKV infection. Vaginal delivery and natural breastfeeding are advised.

The occurrence of Manson’s schistosomiasis in organs of the female reproductive tract is an uncommon event, given that the etiological agent for this disease is a blood parasite that inhabits the mesenteric veins. In this case report, a 45-year-old female patient reported that her first symptoms had been strong pain in the left iliac region around two years earlier. An endovaginal pelvic ultrasonography showed that the left ovary was enlarged, and the report suggested that this finding might be correlated with clinical data and tumor markers. After being examined at several healthcare services, the patient was referred to an oncology service due to suspected neoplasia, where she underwent a left ovariectomy. The result from the histopathological examination showed the presence of granulomatous inflammatory processes surrounding both viable and calcified eggs of Schistosoma mansoni. There was no evidence of any neoplastic tissue. The patient was medicated and followed-up as an outpatient.
