RESUMEN
Objective: Seminal cryopreservation causes significant damage to the sperm; therefore, different methods of cryopreservation have been studied. The aim of the study was to compare the effects of density gradient processing and washing/centrifugation with seminal plasma removal for cryopreservation in semen parameters. Methods: Seminal samples of 26 normozoospermic patients were divided into 3 parts: with seminal plasma; after washing/centrifugation; and after selection through density gradient. The samples were cryopreserved for at least two weeks. Motility, sperm count, morphology and viability were evaluated before cryopreservation and after thawing. Results: Density gradient processing selected motile and viable sperm with normal morphology in fresh samples (p<0.05). Cryopreservation negatively affected all sperm parameters regardless of the processing performed, and even if the sperm recovery was lower in the density gradient after the thawing, progressive motility, total motility, viability and morphology remained higher (p<0.05). Conclusion: Cryopreservation significantly compromises sperm parameters (motility, morphology, viability). In normozoospermic patients, the density gradients select better quality spermatozoa compared to other processing methods; this benefit was kept after thawing.

INTRODUCTION: Suicide is a worldwide health concern and up to date there is no good predictor of it except a previous suicide attempt. Therefore, there are increasing efforts in the understanding of which factors, genetic or environmental, are associated with suicide behaviour. OBJECTIVE: To review evidence of the effect of childhood trauma and impulsivity on suicidal behavior through a systematic review and meta-analysis. METHODS: Searches were conducted on the 12th of June 2021 in the PubMed, Scopus, and Web of Science databases. Two reviewers evaluated each record for eligibility and discussed upon disagreement, when no consensus was reached, a third reviewer was involved to make a decision. RESULTS: A total of 11,530 records were identified through the searches. After duplicates were removed, 6,595 records remained to be screened. The full text was sought for 1,561 records. Our qualitative synthesis included 22 studies, from which 9 were included in the meta-analyses. We found a significant effect of sexual abuse, physical abuse, emotional abuse and physical neglect on suicide attempts in the prisoners, and Substance Use Diorder (SUD) subgroups. Moreover, there was a significant effect of Childhood Trauma Questionnaire (CTQ) total score and emotional neglect dimension for all the subgroups. CONCLUSION: The present study has provided an overview of the state-of-the-art research on childhood trauma and impulsivity and their association with suicidal behavior and quantified their effects on suicide attempts. Hopefully this evidence will be considered in future research and harnessed for clinical gain in detection and treatment of suicide behaviour.

RESUMEN
INTRODUCTION: The handling of antineoplastic drugs should follow strict supervision and safety rules to minimize the occupational exposure risks to professionals involved. The external surface contamination of drug vials is recognized as a health risk. So, our goal was to determine if there is residual contamination on the vials and containers surface of the antineoplastic drugs doxorubicin (DOX) and cyclophosphamide (CP). METHODS: A cross-sectional study was conducted. Samples were collected using a uniform sampling procedure on the inner surfaces of the packages/boxes and the outer surfaces of the vials. The analyzes were executed by high-performance liquid chromatography/mass spectrometry (UHPLC-MS/MS). RESULTS: A total of 209 samples were analyzed, 66 of CP and 143 of DOX. CP levels were detected in nine samples (13.63%), three were below the lower limit of quantification (LLQ) and the other six had contamination levels ranging from 1.24 to 28.04â ng/filter. DOX levels were detected in 36 samples (25.17%), two were below the LLQ and the others had levels between 1.32 and 664.84â ng/filter. The majority of samples with residual contamination were in vials (80.0%), however, boxes also showed contamination. CONCLUSIONS: The results revealed the presence of residual contamination in the vials and packages of CP and DOX drugs. Although the residues found in each sample are small, special care should be taken in the handling and disposal of the antineoplastic drugs. The use of personal protective equipment is fundamental while handling the vials and packaging of cytotoxic drugs.

Introduction: To analyze the factors (socio-demographic, clinical, prenatal care, delivery, postpartum data and anthropometric measures) associated with the birth of small for gestational age newborns.Methods: A cross-sectional study was performed with 15 years old or younger postpartum adolescents divided into small-for-gestational-age newborn (SGA) and non-small-for-gestational age newborn groups (NSGA). Socio-demographic, clinical, prenatal care, delivery, postpartum data and anthropometric measures (triceps skinfold (TS), and mid-arm circumference, (MAC)) were collected.Results: 8,153 women gave birth at the obstetric ward and 364 (4.46%) ≤ 15 years old adolescents were enrolled in the study. The proportion of SGA newborns was 34.61%. The SGA group attended fewer prenatal visits (p = 0.037), had a higher prevalence of nutritional status classified as "very low weight" (p < 0.001) and vaginal delivery (p = 0.023), compared to the NSGA group. The nutritional status and vaginal delivery remained significant even after adjustment for confounders. The prevalence risk for SGA birth was 30% higher in the group of mothers with nutritional status classified as "very low weight" (odds ratio 1.30, 95% confidence interval 1.13 to 1.50) (p < 0.001).Conclusions: 15.4% of adolescents ≤ 15 years of age had an arm circumference compatible with the "very low weight" condition, demonstrating the high prevalence of poor maternal nutritional status in this group. The birth of SGA among adolescents ≤ 15 years of age is independently associated with maternal nutritional status classified as "very low weight" by the mid-arm circumference measures (MAC).

Abstract Residency is still considered the gold standard for quality medical training, and acquiring a professional identity as a specialist is one of its central elements. Residents obtain this identity through both the educational environment and direct interaction with peers and supervisors. However, modifications in health care and educational routines during the recent coronavirus disease 2019 (COVID-19) pandemic have significantly impaired these channels. This study is part of a qualitative research project to analyze professional identity formation in a medical residency program in obstetrics and gynecology at a public hospital in southern Brazil. The authors conducted 28 semi-structured interviews with medical residents and preceptors, as well as a focus group with the residents, which was recorded, transcribed, and analyzed in an effort to construct major analytical categories. Restricted movement and physical contact have forced the use of alternative means of interpersonal interaction, such as communication through social media or instant messaging applications. This has also affected educational activities, such as morning rounds, lectures, and seminars. These changes represent a significant impact, especially in Brazil, where physical proximity is an important cultural feature, even in the work and school environments. We speculate that this new type of virtual interaction will also affect the formation of professional identity among obstetrician-gynecologists. These findings suggest that medical residency programs should be attentive to changes in resident training to ensure that the specialist profile and the expected skills, which are consolidated over many years, are not lost.
Resumo A residência médica ainda é considerada o padrão-ouro para a formação médica de qualidade, sendo o processo de construção da identidade profissional de um médico especialista um de seus elementos centrais.

No entanto, as modificações nas rotinas assistenciais e educacionais durante a recente pandemia de coronavirus disease 2019 (Covid-19) prejudicaram significativamente esses canais. Este estudo faz parte de um projeto de pesquisa qualitativa com o objetivo de analisar a formação da identidade profissional em um programa de residência médica em ginecologia e obstetrícia em um hospital público do sul do Brasil. Os autores realizaram 28 entrevistas semiestruturadas com médicos residentes e preceptores, bem como um grupo focal com residentes. Tanto as entrevistas como as reuniões com o grupo focal foram gravadas, transcritas e analisadas no esforço de construir categorias analíticas. Foi identificado que o movimento restrito e o contato físico forçaram o uso de meios alternativos de interação interpessoal, como a comunicação por meio de mídias sociais ou aplicativos de mensagens instantâneas. Isso também afetou as atividades educacionais, como as rounds, palestras e seminários. Essas mudanças representam um impacto significativo, principalmente no Brasil, onde a proximidade física é uma importante característica cultural, mesmo em ambientes de trabalho e de estudo. Conjectura-se que esse novo tipo de interação virtual também afetará a formação da identidade profissional entre os ginecologistas-obstetras. Esses achados sugerem que os programas de residência médica devem estar atentos às mudanças na formação dos residentes para garantir que o perfil do especialista e as competências esperadas, consolidadas ao longo de muitos anos, não sejam perdidos.

Abstract Objective To evaluate the reproductive and histological characteristics of fresh cultured ovarian tissue from transgender male patients. Methods An in vitro pilot study in which samples were collected during sex reassignment surgery for transgender male patients. The ovarian cortex was cut into fragments of 2 mm, 3mm, and 4 mm, and placed in a 96-well plate suitable for cultivation at days 0, 2, 4, 6, and 8, when the histology was analyzed. Results Stromal hyperplasia was observed in all samples, and it was not associated with the obtainment of primordial or primary follicles. Peripheral reduction in cell count was also a recurrent finding. Primordial and primary follicles were identified with a heterogeneous pattern in fragments from the same patient and from different patients, and follicles in more advanced stages of development (secondary and antral) were not found. There was an association between the diameter of the ovarian fragments and the identification of primary follicles (p=0.036). The number of days in culture was associated with histological signs of tissue damaging in the fragments (p=0.002). The total number of follicles identified in the samples with 2mm in diameter was significantly lower than in those that measured 4mm in diameter (p=0.031). Conclusion A diameter of 4mm is suitable for ovarian tissue culture with the benefit of ease of handling. Even after prolonged exposure to testosterone, the ovarian fragments presented primordial and primary follicles, maintaining viability throughout the days they were exposed to the culture. Freezing the ovarian cortex of transgender patients who will undergo surgery for gender reassignment would be an interesting option, in the future, for the preservation of fertility.

OBJECTIVE: Approximately 15% of the couples suffer from infertility. Half of the cases of infertility are due to male factors. Several sperm function tests have been proposed to evaluate male fertility, but sperm analysis is still the first and most important diagnostic test for male infertility. The prognostic value of semen characteristics such as concentration, morphology and motility markers are often confused with male infertility. Evaluation of seminal parameters and classification for normality remains a frequent topic of discussion. METHODS: This study evaluated 477 semen samples from men undergoing investigation or infertility treatment between 2011 and 2015. RESULTS: The spermograms of 401 patients were deemed abnormal based on the 1999 World Health Organization (WHO) criteria; the number changed to 223 when the spermograms were assessed based on the 2010 WHO criteria and to 200 when Total Motile Sperm Count (TMSC) was used as the criterion. Sperm morphology was the item in the criteria that most significantly changed spermogram classification. Normality parameters became less rigid from 1999 to 2010, thereby significantly changing the proportion of individuals no longer described as infertile/subfertile. CONCLUSIONS: The classification based on TMSC could not differentiate between fertile and infertile subjects for not taking sperm morphology into account. Nevertheless, it may be helpful in cases where intrauterine insemination is indicated.

INTRODUCTION: Our goal was to demonstrate the effects of occupational exposure to antineoplastic drugs on oxidative stress parameters and DNA damage in health professionals who manipulate and administer antineoplastic drugs in a University Hospital in Southern Brazil. METHODS: The case-control study with a longitudinal design, involved 64 individuals, 29 of them pharmacists, pharmacy technicians and nurses who were occupationally exposed to antineoplastic drugs and 35 professionals who were not exposed. Gene mutations were determined by micronucleus from salivary fluid; DNA damage by comet assay and oxidative stress parameters in whole blood were also evaluated. RESULTS: All workers exposed to antineoplastic drugs used personal protective equipment (PPE). It was demonstrated that the total nonprotein thiol and thiobarbituric acid reactive substances levels showed interaction between group and time, with higher levels one week after handling/administration of antineoplastic drugs in the exposed group (GEE, p ≤ 0.0001 and p = 0,013, respectively). Additionally, there was a group effect on the activities of the catalase and glutathione peroxidase antioxidant enzymes (GEE, p = 0.027 and p ≤ 0.0001, respectively), and workers occupationally exposed to antineoplastic drugs had higher enzyme activities compared to those not exposed. No genotoxic damage was demonstrated through the evaluated parameters. CONCLUSIONS: Despite the correct use of PPE, professionals occupationally exposed to antineoplastic drugs were more susceptible to oxidative stress than those not exposed. The evaluation of the studied parameters is especially important for the definition of conducts and practices in the area, always in search of guaranteeing the establishment of a rational policy to protect workers' health.

Introduction: Although, in Brazil, much has been done to encourage the creation and maintenance of graduate programs, there remains a lack of means to assess and measure the professional outcomes of graduates. The objective is to understand the trajectory of doctoral graduates from the Graduate Program in Medicine: Medical Sciences (PPGCM), School of Medicine, Universidade Federal do Rio Grande do Sul (UFRGS), and propose an index for academic performance and professional placement. Methods: A cross-sectional study was conducted. Data available at CV Lattes database of the National Council for Scientific and Technological Development (CNPq) were collected on doctoral graduates from the PPGCM, from 1987 to 2014. Only data pertaining to their origin, undergraduate and master's degrees, intellectual output, academic performance, and professional placement were retrieved. Results: Data on 324 doctoral graduates were analyzed, 221 had graduated in medicine. Undergraduate degree, employment at a public university, working as a doctoral-level advisor, working as a master's-level advisor, CNPq research productivity grantee, and having a recorded h-index in the Lattes curriculum were collected. The coefficient of determination (R 2 ) demonstrated that the variables included in the model explain 99% of the hierarchical model. Conclusion: The results show that the graduates have contributed to developing qualified knowledge disseminated in international newspapers, training human resources, interacting and creating partnerships in the workplace, managing and passing on knowledge, as well as fostering knowledge in the area of medical sciences with regional, national, and international relevance.

Introduction: Depression among human immunodeficiency virus (HIV)-seropositive individuals has been associated with reduced quality of life. The aim of the study was to evaluate the effect of depressive symptoms and HIV exposure on mean quality of life scores in HIV-seropositive and HIV-seronegative postpartum women. Methods: A cross-sectional study was conducted with two groups: 80 HIV-seropositive and 80 HIV-seronegative postpartum women. The Edinburgh Postnatal Depression Scale and the World Health Organization Quality of Life short-version scale were used to assess presence of depressive symptoms and quality of life scores. Two-way analysis of variance was used to compare the effects of depressive symptoms, HIV exposure and interaction between depressive symptoms and HIV exposure on mean quality of life scores, with p < 0.05 considered statistically significant. Results: Depressive symptoms were present in 35% (28) of HIV-seropositive and 17.5% (14) of HIV-seronegative participants (p = 0.02). The interaction between depressive symptoms and HIV exposure was not significant for any quality of life domain. The main effect of HIV exposure was also not significant. Depressive symptoms had a negative influence on quality of life scores in all domains (physical health, psychological health, social relationships and environment) (p < 0.001). Conclusions: The quality of life of pregnant women is negatively influenced by the presence of depressive symptoms. (AU)

PURPOSE: The semaphorins are related to angiogenesis and cell proliferation depending on the tissue. The purpose of this study was to assess gene expression of class 3 semaphorin (SEMA3A-F) and protein expression of semaphorin 3A (SEMA3A) within human endometrium throughout the menstrual cycle. METHODS: Gene expression of SEMA3A-F was analyzed by real-time PCR (qRT-PCR) and protein expression of SEMA3A was analyzed by ELISA in endometrial biopsies in the proliferative and secretory phase of the menstrual cycle. RESULTS: Gene expression of SEMA3A, SEMA3C, SEMA3D, and SEMA3E was statistically significant decreased in secretory compared to proliferative phase endometrium (p < 0.05). Accordingly, SEMA3A protein expression in the secretory phase was lower than protein expression in proliferative phase endometrium (p ≤ 0.05). CONCLUSION: SEMA3A, 3C, 3D, and 3E are possibly related to cell proliferation in the endometrium, being more expressed in the proliferative phase of the cycle. This finding may stimulate studies of class 3 semaphorins as a possible target for treatment of endometrial pathologies.

PURPOSE: To evaluate the efficiency/safety of Brilliant Cresyl Blue (BCB) staining as a selection method of developmentally competent immature human oocytes. MATERIALS AND METHODS: Immature oocytes of 32 pregnant women were recovered during cesarean section (CS). After retrieval, 92 oocytes were randomly divided into two groups: control (directly disposed to in vitro maturation - IVM) and treated - exposed to BCB 26 µM during 60 min. After staining, the treated group was classified as cytoplasm coloration, BCB positive (blue) or negative (colorless), and then disposed to IVM. Nuclear status was checked after 24 and 48 h of IVM. Nuclear maturation (polar body extrusion), meiosis resumption (absence of germinal vesicle) and degeneration rates were evaluated among the three groups (control, BCB positive and BCB negative) using Generalized Estimating Equations, followed by Bonferroni's correction for multiple comparisons. RESULTS: Nuclear maturation was higher in BCB positive compared to BCB negative, after 24 and 48 h of IVM (p = .004 and p = .032). The control group was equal to BCB positive. There was no difference among groups analyzing meiosis resumption and degeneration rates. CONCLUSION: The BCB test can be a good marker in pre-selection procedures of developmentally competent human oocytes aspirated during CS.

OBJECTIVE: To determine the prevalence of preeclampsia (PE) in adolescents and to evaluate its association with risk factors for, and the occurrence of, adverse maternal and fetal outcomes. RESULTS: Of 3006 deliveries, 533 (17.7%) were from teenage mothers, with twenty-eight (5.3%) presenting PE; 17.8% of these cases were classed as severe. Vitamin and mineral supplementation was associated with the occurrence of PE (p=0.034). Puerperal complications and prematurity were more frequent in the PE group. CONCLUSIONS: Prevalence of PE among adolescents was similar to the literature data and was associated with high rates of preterm birth and puerperal complications.

Aim To assess ovarian reserve (OVR) by means of follicle-stimulating hormone (FSH), anti-Müllerian hormone (AMH), and antral follicle count (AFC) measurement in eumenorrheic women with breast cancer, exposed to gonadotoxic chemotherapy. Method Fifty-two women (35.3 ± 3.8 years old) with breast cancer and undergoing cyclophosphamide-containing chemotherapy were enrolled. The assessment was performed before chemotherapy (T1) and after 2 (T2) and 6 months (T3). Results Six months after chemotherapy, the prevalence of regular cycles was 60%. Anti-Müllerian hormone decreased down to undetectable levels at T2 and T3 (T1: 2.53 [1.00-5.31]; T2 < 0.08; T3: < 0.08 [< 0.08-1.07] ng/mL), (p < 0.0001). Antral follicle count was 11 [8.0-13.5] follicles at T1 and lower at T2 (5.50 [3.75-8.0] and T3 (5.0 [2.5-7.0]) (p < 0.0001). In patients who remained with regular cycles during chemotherapy or resumed normal menses, FSH and estradiol levels remained unchanged. Conclusion Anti-Müllerian hormone and AFC are useful as markers of OVR decline in women exposed to chemotherapy. Follicle-stimulating hormone is only adequate in women who become amenorrheic.

Resumo Objetivo Avaliar a reserva ovariana (OVR) através da contagem de folículos antrais (AFC), dosagem sérica de hormônio folículo estimulante (FSH) e hormônio anti-Mülleriano (AMH) em mulheres com câncer de mama submetidas a quimioterapia gonadotóxica. Método Foram incluídas na pesquisa 52 mulheres (35,3 ± 3,8 anos) com câncer de mama, em tratamento com quimioterapia com ciclofosfamida. As dosagens e medidas foram realizadas antes do início da quimioterapia (T1) e após 2 (T2) e 6 meses (T3). Resultados Seis meses após quimioterapia, a prevalência de ciclos regulares foi de 60%. O AMH sérico diminuiu a níveis indetectáveis em T2 e T3 (T1: 2,53 [1,00–5,31] ]; T2 < 0,08; T3: < 0,08 [< 0,08–1,07] ng/mL) (p< 0,0001). A contagem de folículos antrais foi de 11 [8,0–13,5] folículos em T1, e ainda menor em T2 (5,50 [3,75–8,0] e T3 (5,0 [2,5–7,0]), (p< 0,0001). Em pacientes que mantiveram ciclos regulares durante a quimioterapia ou retomaram a menstruação normalmente, os níveis de FSH e estradiol permaneceram inalterados. Conclusão O AMH e a AFC são marcadores úteis do declínio da OVR em mulheres expostas à quimioterapia. O FSH só é adequado em mulheres que se tornam amenorreicas.

Uterine leiomyomas are the most common benign smooth muscle cell tumors in women. Estrogen (E2), progesterone (P4) and environmental factors play important roles in the development of these tumors. New treatments, such as mifepristone, have been proposed. We evaluated the gene expression of total (PRT) and B (PRB) progesterone receptors, and the histone acetyltransferase (HAT) and deacetylase (HDAC) activity after treatment with E2, P4 and mifepristone (RU486) in primary cell cultures from uterine leiomyoma and normal myometrium. Compared to myometrium, uterine leiomyoma cells showed an increase in PRT mRNA expression when treated with E2, and increase in PRB mRNA expression when treated with E2 and P4. Treatment with mifepristone had no significant impact on mRNA expression in these cells. The HDAC activity was higher in uterine leiomyoma compared to myometrial cells after treatment with E2 and E2 + P4 + mifepristone. HAT activity was barely detectable. Our results suggest that ovarian steroid hormones modulate PR, and mifepristone was unable to decrease PRT and PRB mRNA. The higher activity of HDAC leiomyoma cells could be involved in transcriptional repression of genes implicated in normal myometrium cell function, contributing to the maintenance and growth of uterine leiomyoma.

OBJECTIVE: The study aimed to investigate the vocal range of oral contraceptive (OC) users aged between 20 and 30 years. STUDY DESIGN: This is a cross-sectional study. METHODS: Forty-eight women aged 20-30 years who used low-dose OCs and 24 age-matched women who did not use oral monophasic contraceptives (w/oOC) were enrolled. Acoustic analysis was performed using the Motor Speech Profile program, Model 4341 (Kay Elemetrics Corp). Data were analyzed using generalized estimating equation. RESULTS: In the w/oOC group, the highest vocal tones in the sentence uttered using exclamatory intonation were similar in the follicular phases of two cycles (F1: 289 ± 46 Hz; F2: 284 ± 61 Hz). In the luteal phase of the first cycle, the vocal tones were lower, whereas in the second cycle they were higher than the tones in both follicular phases (L1: 274 ± 42 Hz; L2: 291 ± 62 Hz) (P = 0.056). In the highest vocal tones of the same sentence uttered using exclamatory intonation, the OC group showed lower tones (284 ± 53 Hz) than the w/oOC group (298 ± 44 Hz) (P = 0.048). In the lowest vocal tones of utterances of joy, the OC group showed higher values (180 ± 39 Hz) than the w/oOC group (169 ± 44 Hz) (P = 0.024). The close proximity of the highest to the lowest values of utterances of joy in the OC group (321 ± 59 Hz and 180 ± 39 Hz), when related to the w/oOC group (338 ± 65 Hz and 169 ± 44 Hz), suggests a reduced vocal modulation. CONCLUSIONS: The present findings demonstrate that the use of low-dose OCs influences the vocal range of women during menacme.
