Anemia is a very frequent event among pregnant women. There are evidences of differences in the incidence of dental caries between pregnant and nonpregnant women, but the relationship between salivary iron (Fe) and serummarkers of anemia and caries development has not been investigated.
To evaluate the correlation between salivary (Fe) and serum iron (Fe, ferritin and hemoglobin) parameters in pregnant women with the development of dental caries.
A prospective cohort was conducted with 59 women. The outcome of interest was represented by new dental caries lesions during pregnancy, using the Nyvad criteria. Pregnant women were evaluated at three clinical times: up to the 16th week of gestational age (GA) (T1), in the last trimester of pregnancy (T2), and postpartum (T3), at the Mother and Child Unit ofUniversityHospital of the Universidade Federal doMaranhão.A stimulated saliva sample was collected for biochemical analysis of salivary Fe, and a blood sample was collected early in the morning. The correlation between salivary and serum Fe was evaluated through the Pearson correlation test. Analysis of variance (ANOVA) and Kruskal-Wallis were used to compare the means of anemia parameters at different times. The Student's t and Mann-Whitney tests were used to compare the anemia parameters between the groups of pregnant women (with and without new caries lesions).
SerumFe concentrationswere higher in the first trimester of pregnancy and lower after delivery (p = 0.036). It was also observed that the ferritin concentrations were higher in the first trimester and lower at the end of gestation (p = 0.011). Therewas no association between the expositions of salivary iron and anemia, and the development of dental caries. There was a positive correlation between serum Fe in T1 and salivary Fe in T2 (p < 0.05).
The serummarkers of anemiaweremore prevalent in the last trimester of pregnancy.

Expectant follow-up for biopsy-proven cervical intraepithelial neoplasia (CIN) 1 is the current recommendation for the management of this lesion. Nevertheless, the performance of the biopsy guided by colposcopy might not be optimal. Therefore, this study aimed to calculate the rate of underdiagnoses of more severe lesions in women with CIN 1 diagnosis and to evaluate whether age, lesion extent and biopsy site are factors associated with diagnostic failure.
Eighty women with a diagnosis of CIN 1 obtained by colposcopy-guided biopsy were selected for this study. These women were herein submitted to large loop excision of the transformation zone (LLETZ). The prevalence of lesions more severe than CIN 1 was calculated, and the histological diagnoses of the LLETZ specimens were grouped into two categories: "CIN 1 or less" and "CIN 2 or worse."
The prevalence of lesions diagnosed as CIN 2 or worse in the LLETZ specimens was of 19% (15/80). Three women revealed CIN 3, and 1 woman revealed a sclerosing adenocarcinoma stage I-a, a rare type of malignant neoplasia of low proliferation, which was not detected by either colposcopy or previous biopsy. The underdiagnosis of CIN 2 was not associated with the women's age, lesion extension and biopsy site.
The standard methods used for the diagnosis of CIN 1 may underestimate the severity of the true lesion and, therefore, women undergoing expectant management must have an adequate follow-up.

To evaluate the correlation between upper limb functionality and quality of life in women with five-year survival following breast cancer surgical treatment. The secondary objective was to evaluate the function of the ipsilateral upper limb and the quality of life in relation to the type of surgery and the presence of pain.
The Disabilities of Arm, Shoulder and Hand (DASH), and the Functional Assessment of Cancer Therapy - Breast plus Arm Morbidity (FACTB + 4) questionnaires were used to evaluate upper limb function and quality of life respectively. Data distribution was verified by the Shapiro-Wilk test. Pearson's correlation coefficient was used for the parametric variables, and Spearman's rank correlation coefficient was used for the distribution of non-parametric variables. The statistical significance was set at 5% (p < 0.05).
The study included 30 patients, with a mean age of 51.23 (±8.72) years. The most common complications were: pain (50%), adherence (33.3%), and nerve lesion (20.0%). There was a moderate negative correlation between the instruments DASH and FACTB + 4 (total score), r = -0.634, and a strong negative correlation between the DASH and the FACTB + 4 armsubscale, r = -0.829. The scores of both questionnaires showed significant difference on the manifestation of pain. However, there was no significant difference found when comparing the scores considering the type of surgery performed.
Five years after surgery, the patients showed regular functionality levels on the ipsilateral upper limb and decreased quality of life, especially in the group manifesting pain.

To describe the frequencies of chromosomal abnormalities found in abortion material, and to observe its correlation to maternal age.
A retrospective study was conducted based on data obtained from the databank of a medical genetics laboratory in Belo Horizonte, MG, Brazil. A total of 884 results from products of conception analysis were included, 204 of which were analyzed by cytogenetics, and 680bymolecular biology basedon quantitative fluorescence polymerase chain reaction (QF-PCR). The frequency of individual chromosomal aberrations and the relationship between the presence of anomalies and maternal age were also evaluated.
The conventional cytogenetics technique was able to detect 52% of normal and 48% of abnormal results in the analyzed material. Quantitative fluorescence polymerase chain reaction revealed 60% of normal and 40% of abnormal results from the samples evaluated by this method. The presence of trisomy 15 was detected only by cytogenetics, as it was not included in the QF-PCR routine investigation in the laboratory. A significant increase in abnormal results was observed among women aged 35 years or older compared with younger women (p = 0.02).
Chromosomal aberrations are still a major cause of spontaneous abortion, and the conventional cytogenetics technique is efficient for miscarriage material analysis, but molecular methods such as QF-PCR are adequate complementary strategies to detect the major chromosomal anomalies, leading to technical reports with reliable results.

To assess the prevalence of hypovitaminosis D, altered arterial blood pressure, and serum levels of glucose and lipids in community-dwelling women in the city of Ribeirão Preto, in the southeast of Brazil.
Thiswas a cross-sectional studyof women aged40-70years old.Calciumintake and level of sun exposure were assessed by means of a questionnaire. A blood sample was used to determine glucose, lipid profile and 25-hydroxyvitaminD(25[OH]D) concentration.
Ninety-one women were enrolled (age = 54.2 ± 7.1 years). Themean serum 25(OH)D concentration was 25.7 ± 8.9 ng/mL. A total of 24 (26.4%) women had 25 (OH)D levels < 20 ng/mL. Seventy women (76.9%) had 25(OH)D levels < 30 ng/mL. Seventy-five women (90.4%) had inadequate calcium intake, and 61 women (67%) had appropriate sun exposure, 49 of whom (80.3%) had serum 25(OH)D levels < 30 ng/mL.
This study indicates that even in community-dwelling women, living in a city with high sun exposure, serum levels of 25(OH)D > 30 ng/ml are hardly reached. Thus, it is probable that other intrinsic factors besides sun exposure may regulate the levels of vitamin D.

To evaluate the diagnostic accuracy of elastography for breast cancer identification in patients with indeterminate lesions on ultrasound.
This prospective, descriptive study included patients with indeterminate breast lesions in the ultrasound and with indication for percutaneous or surgical biopsy. The elastography was evaluated by qualitative analysis and by two methods for the semi quantitative analysis.
We evaluated 125 female patients with 159 lesions, with a mean age of 47 years, and a range of 20-85 years. Ultrasound has shown to be a method with good sensitivity (98.1%), but with a lower specificity (40.6%). On the elastography qualitative analysis, the specificity and accuracy were of 80.2% and 81.8% respectively. The mean size of the lesions showed no difference in classification by elastography. For the semiquantitative elastography, the mean values of the malignant lesions were statistically higher when compared with the subcutaneous tissue or the adjacent fibroglandular tissue. The analysis of the receiver operating characteristic (ROC) curves for these two semiquantitativemethods showed that both are considered satisfactory, with an area under the curve above 0.75 and statistical significance (p < 0.0001). The best results were obtained when using the findings of combined conventional ultrasound and qualitative elastography, with 100% sensitivity and 63.2% specificity.
Elastography can be a useful complementary method, increasing the specificity and diagnostic accuracy of conventional ultrasound for the diagnosis of breast cancer in patients with indeterminate breast lesions.

To evaluate the association of age at first sexual intercourse with the results of the cervicovaginal cytology.
Observational analytical study about the prevalence of altered cervicovaginal cytology results in women aged between 18 and 34 years from a densely populated area in Brazil, during 10 years. The patients were stratified into 2 categories according to their age at first sexual intercourse (13-16 years and 17-24 years).
From the total of 2,505,154 exams, 898,921 tests were in accordance with the inclusion criteria. Considering women with 4 years or less from the first sexual intercourse as a reference, those with 5 to 9 years and 10 years or more showed a higher prevalence of high-grade squamous intraepithelial lesions (HSILs). Women with an earlier onset of sexual intercourse (13-16 years) showed higher prevalence ratios for atypical squamous cells (ASC), low-grade squamous intraepithelial lesion (LSIL) and HSIL. The prevalence ratio for HSIL adjusted by age at diagnosis and by age at first sexual intercourse was higher only for women with an earlier onset of sexual intercourse.
The age of first sexual intercourse could be a variable that might qualify the selection among young women who are really at a higher risk for HSIL.

To investigate the association between the intensity of climacteric symptoms and sexual dysfunction in women aged 40 to 65 years.
Observational, analytic, cross-sectional study conducted with 63 women aged 40 to 65 treated at the gynecology outpatient clinic of a public hospital in northeastern Brazil. A questionnaire was used to collect identification data, clinical information, gynecological-obstetric data, lifestyle traits and information on chronic diseases. Climacteric symptoms and sexual function were evaluated by means of the Blatt-Kupperman index and the Female Sexual Function Index (FSFI) respectively. The association between the two indices was investigated using the chi-squared test; the difference in mean scores on the FSFI as a function of menopausal status was evaluated by Student's t-test. The significance level was set to p < 0.05.
The mean value of the Blatt-Kupperman index was 26.42 (standard deviation [SD]: 4.52); 36.51% of the women exhibited severe symptoms. The mean score on the FSFI was 21.84 (SD: 4.11). More than half of the analyzed women (58.73%) exhibited sexual dysfunction (FSFI ≤ 26.5). Regarding the association between the Blatt- Kupperman index and the FSFI, the greater the intensity of the climacteric symptoms (Blatt-Kupperman), the higher the frequency of sexual dysfunction (FSFI). Sexual dysfunction was exhibited by 100% of the participants with severe climacteric symptoms, 70.59% of those with moderate symptoms, and only 9.09% with mild symptoms (p < 0.001).
The application of the Blatt-Kupperman index and of the FSFI allowed the detection of an association between the severity of climacteric symptoms and the prevalence of sexual dysfunction.
