To describe the trends in the prevalence of macrosomia (birth weight ± 4,000 g) according to gestational age in Brazil in the periods of 2001-2010 and 2012-2014.
Ecological study with data from the Brazilian Live Birth Information System (SINASC, in the Portuguese acronym) regarding singleton live newborns born from 22 gestational weeks. The trends in Brazil as a whole and in each of its five regions were analyzed according to preterm (22-36 gestational weeks) and term (37-42 gestational weeks) strata. Annual Percent Changes (APCs) based on the Prais-Winsten method and their respective 95% confidence intervals (CIs) were used to verify statistically significant changes in 2001-2010.
In Brazil, the prevalence of macrosomic births was of 5.3% (2001-2010) and 5.1% (2012-2014). The rates were systematically higher in the North and Northeast Regions both in the preterm and in term strata. In the preterm stratum, the North Region presented the highest variation in the prevalence of macrosomia (+137.5%) when comparing 2001 (0.8%) to 2010 (1.9%). In the term stratum, downward trends were observed in Brazil as a whole and in every region. The trends for 2012-2014 were more heterogeneous, with the prevalence systematically higher than that observed for 2001-2010. The APC in the preterm stratum (2001-2010) showed a statistically significant trend change in the North (APC: 15.4%; 95%CI: 0.6-32.3) and South (APC: 13.5%; 95%CI: 4.8-22.9) regions. In the term stratum, the change occurred only in the North region (APC:-1.5%; 95%CI: -2.5--0.5).
The prevalence of macrosomic births in Brazil was higher than 5.0%. Macrosomia has potentially negative health implications for both children and adults, and deserves close attention in the public health agenda in Brazil, as well as further support for investigation and intervention.

To identify the prevalence of anemia and its relation to food insecurity (FI) and other determinants in pregnant women.
A cross-sectional, cohort-nested study, with the participation of 245 pregnant women who were cared for at Family Health Units in the municipality of Santo Antônio de Jesus, Bahia, Brazil. The participants underwent blood tests for hemoglobin levels, anthropometric examinations, and answered a structured questionnaire. The hemoglobin (Hb) parameter (Hb < 11 g/dL) was used for the classification of the diagnosis of anemia. Food insecurity was evaluated using the North American short-scale food insecurity assessment. Logistic regression was adopted for the statistical analyses, based on a hierarchical conceptual model that enabled the measurement of the decomposition of the total effect of its non-mediated and mediated components using the proposed hierarchical levels.
The prevalence of anemia in the studied population was of 21.8%, and the average hemoglobin was 12.06 g/dL (standard deviation [SD]: 1.27). Food insecurity was identified in 28.16% of the pregnant women. The average maternal age was 25.82 years (SD: 5.94). After ranking, the variables positively associated with anemia remained significant: FI (odds ratio [OR] =3.63; 95% confidence interval [95%CI]: 1.77-7.45); not undergoing prenatal care (OR = 5.15;95%CI: 1.43-18.50); multiparity (OR = 2.27;95%CI: 1.02-5.05); and non-supplementation of iron medication (OR = 2.45; 95%CI: 1.04-5.76). The results also indicated that the socioeconomic and environmental factors were largely mediated by food insecurity and factors regarding prenatal care.
In the present study, the chance of occurrence of anemia in pregnant women was significantly higher,mainly among women: in situations of food insecurity, not undergoing prenatal care, not having received iron supplements, and who are multiparous.

To describe the reproductive variables associated with different sickle cell disease (SCD) genotypes and the influence of contraceptive methods on acute painful episodes among the women with the homozygous hemoglobin S (HbSS) genotype.
A cross-sectional study was conducted between September of 2015 and April of 2016 on 158 women afflicted with SCD admitted to a hematology center in the Northeast of Brazil. The reproduction-associated variables of different SCD genotypes were assessed using the analysis of variance (ANOVA) test to compare means, and the Kruskal-Wallis test to compare medians. The association between the contraceptive method and the acute painful episodes was evaluated by the Chi-square test.
Themean age of women with SCD was 28.3 years and 86.6% were mixed or of African-American ethnicity. With respect to the genotypes, 134 women (84.8%) had HbSS genotype, 12 women (7.6%) had hemoglobin SC (HbSC) disease genotype, and 12 (7.6%) were identified with hemoglobinopathy S-beta (S-β) thalassemia. The mean age of HbSS diagnosis was lower than that of HbSC disease, the less severe formof SCD (p < 0.001). The mean age ofmenarche was 14.8 ± 1.8 years for HbSS and 12.7 ± 1.5 years for HbSC (p < 0.001). Among women with HbSS who used progestin-only contraception, 16.6% had more than 4 acute painful episodes per year. There was no statistically significant difference when compared with other contraceptive methods.
With respect to reproduction-associated variables, only the age of the menarche showed delay in HbSS when compared with HbSC. The contraceptive method used was not associated with the frequency of acute painful episodes among the HbSS women.

To determine the clinical and epidemiological characteristics of abdominal wall endometriosis (AWE), as well as the rate and recurrence factors for the disease.
A retrospective study of 52 women with AWE was performed at Universidade Estadual de Campinas from 2004 to 2014. Of the 231 surgeries performed for the diagnosis of endometriosis, 52 women were found to have abdominal wall endometriosis (AWE). The frequencies, means and standard deviations of the clinical characteristics of these women were calculated, as well as the recurrence rate of AWE. To determine the risk factors for disease recurrence, Fisher’s exact test was used.
The mean age of the patients was 30.71 ± 5.91 years. The main clinical manifestations were pain (98%) and sensation of a mass (36.5%).We observed that 94% of these women had undergone at least 1 cesarean section, and 73% had used medication for the postoperative control of endometriosis. The lesion was most commonly located in the cesarean section scar (65%). The recurrence rate of the disease was of 26.9%. All 14 women who had relapsed had surgical margins compromised in the previous surgery. There was no correlation between recurrent AWE and a previous cesarean section (p = 0.18), previous laparotomy (p = 0.11), previous laparoscopy (p = 0.12) and postoperative hormone therapy (p = 0.51).
Women with previous cesarean sections with local pain or lumps should be investigated for AWE. The recurrence of AWE is high, especially when the first surgery is not appropriate and leaves compromised surgical margins.

the aim of this study was to evaluate the pattern of human papillomavirus (HPV) detection in an 11.3-year post-vaccination period in a cohort of adolescent and young women vaccinated or not against HPV 16/18.
a subset of 91 women from a single center participating in a randomized clinical trial (2001-2010, NCT00689741/00120848/00518336) with HPV 16/18 AS04- adjuvanted vaccine was evaluated. All women received three doses of the HPV vaccine (n = 48) or a placebo (n = 43), and cervical samples were collected at 6-month intervals. Only in this center, one additional evaluation was performed in 2012. Up to 1,492 cervical samples were tested for HPV-DNA and genotyped with polymerase chain reaction (PCR). The vaccine group characteristics were compared by Chi-square or Fisher exact or Mann-Whitney test. The high-risk (HR)-HPV 6-month-persistent infection rate was calculated. The cumulative infection by HPV group was evaluated by the Kaplan-Meier method and the log-rank test.
the cumulative infection with any type of HPV in an 11.3-year period was 67% in the HPV vaccine group and 72% in the placebo group (p = 0.408). The longitudinal analysis showed an increase of 4% per year at risk for detection of HR-HPV (non-HPV 16/ 18) over time (p = 0.015), unrelated to vaccination. The cumulative infection with HPV 16/18 was 4% for the HPV vaccine group and 29% for the placebo group (p = 0.003). There were 43 episodes of HR-HPV 6-month persistent infection, unrelated to vaccination.
this study showed themaintenance of viral detection rate accumulating HR-HPV (non-HPV-16-18) positive tests during a long period post-vaccination, regardless of prior vaccination. This signalizes that the high number of HPV-positive testsmay be maintained after vaccination.

To assess themedical doctors andmedical students’ opinion regarding the evidence and ethical background of the performance of vulvovaginal aesthetic procedures (VVAPs).
Cross-sectional online survey among 664 Portuguese medical doctors and students.
Most participants considered that there is never or there rarely is amedical reason to perform: vulvar whitening (85.9% [502/584]); hymenoplasty (72.0% [437/607]); mons pubis liposuction (71.6% [426/595]); “G-spot” augmentation (71.0% [409/576]); labia majora augmentation (66.3% [390/588]); labia minora augmentation (58.3% [326/559]); or laser vaginal tightening (52.3%[313/599]).Gynecologists and specialistsweremore likely to consider that there are no medical reasons to performVVAPs; the opposite was true for plastic surgeons and students/residents. Hymenoplasty raised ethical doubts in 51.1% (283/554) of the participants. Plastic surgeons and students/residents were less likely to raise ethical objections, while the opposite was true for gynecologists and specialists. Most considered that VVAPs could contribute to an improvement in self-esteem(92.3% [613/664]); sexual function (78.5% [521/664]); vaginal atrophy (69.9% [464/664]); quality of life (66.3% [440/664]); and sexual pain (61.4% [408/664]).
While medical doctors and students acknowledge the lack of evidence and scientific support for the performance of VVAPs, most do not raise ethical objections about them, especially if they are students or plastic surgeons, or if they have had or have considered having plastic surgery.

The literature that supports and recommends the practice of exercise during pregnancy is extensive.However, although a more complete research on ways to evaluate the physical activity performedby pregnant women has been perfomed, it is found that there is no gold standard and that the articles in the area are inconclusive. Thus, the objective of the present article is to review relevant aspects, such as, technique and applicability of the different methods for the assessment of physical activity during pregnancy to providemore reliable and safe information for health professionals to encourage their pregnant patients to engage in the practice of physical activity. This review concluded that all tools for the analysis of physical activity have limitations. Thus, it is necessary to establish the objectives of evaluation in an appropriate manner, as well as to determine their viability and costeffectiveness for the population under study.
