RESUMO

Stress, infections, and psychological and social well-being can affect the reproductive system. Activation of the hypothalamic-pituitary-adrenal axis can disrupt ovarian cyclicity. Estrogens can modulate stress responsiveness and mood. Thus, understanding this interaction and how it modulates the menstrual cycle is crucial for women's reproductive health. PURPOSE: The objective of this study was to analyze the influence of a stressor, a period of the Covid-19 pandemic when there were no vaccines available yet, on the psychological state of women aged 18 to 45 years; as well as the influence of mental health on the menstrual cycle, considering the influence of age and hormonal contraceptives. METHOD: Online questionnaire using the Google Forms platform was used. RESULTS: There is a high prevalence of the onset of new psychosocial symptoms. Moreover, most women reported some type of change in their menstrual cycles. The women who were using hormonal contraceptives demonstrated a higher frequency of spotting and menstrual color alterations, while women without hormonal contraceptives demonstrated a higher frequency of cycle duration and menstrual odor alterations. Women without hormonal contraceptives were more susceptible to the development of psychosocial symptoms. Younger adult women were more affected by menstrual changes and psychosocial symptoms. Close to 90% of women who reported several psychosocial symptoms had changes in their menstrual cycles. CONCLUSION: These data suggest the impact of stressors, such as a period of the pandemic, on mental health and menstrual cycles, and younger adult women can be more susceptible. This reflects the relationship between mental and reproductive health.

RESUMO

Abnormal uterine bleeding (AUB) is a bleeding from the uterine corpus that is abnormal in regularity, volume, frequency or duration. It encompasses heavy menstrual bleeding, irregular menstrual bleeding and intermenstrual bleeding, which are common symptoms among women of reproductive age, impacting their overall well-being. Menstruation involves interactions between endometrial epithelial and stromal cells, immune cell influx, and changes in endometrial vasculature. These events resemble an inflammatory response with increased vessel permeability, tissue breakdown, and the arrival of innate immune cells. However, the mechanisms of menstrual cessation are poorly understood. AUB can be related to structural causes (polyp, adenomyosis, leiomyoma, malignancy/hyperplasia) and nonstructural conditions (coagulopathy, ovulatory dysfunction, endometrial, iatrogenic). While transvaginal ultrasound is the primary method for the screening of intracavitary lesions, saline infusion sonohysterography is more accurate to detect endometrial polyps and submucous leiomyomas, while hysteroscopy with biopsy remains the reference method for a definitive diagnosis. The main goals in managing AUB are addressing and correcting the underlying primary cause, if possible, and establishing a regular bleeding pattern or amenorrhea, which can be done with antifibrinolytic agents, progestins, gonadotropin-releasing hormone agonists and antagonists, or surgical interventions, each one with specific indications and limitations. Further research is necessary to assess the effectiveness and the long-term effects of various medical and surgical treatments. Meanwhile, the availability of diagnostic methods such as transvaginal ultrasound and hysteroscopy and the universal distribution of medical treatments for AUB should be prioritized by policymakers to minimize the diagnostic and treatment delay and thus reduce the risk of AUB-related anemia and the need of hysterectomy.

RESUMO

OBJECTIVE: To analyze differences in the menstrual pattern, age at menarche, and body mass index (BMI) in adolescents with Hypothalamic-Pituitary-Ovarian (HPO) axis immaturity and Polycystic Ovary Syndrome (PCOS) through a systematic review and meta-analysis. METHODS: The PubMed, EMBASE, Web of Science, Virtual Health Library, Scopus databases were searched using combinations of descriptors. Study quality was assessed using the Newcastle-Ottawa Scale. For data analysis, the results were grouped into PCOS group and NPCOS group (HPO axis immaturity). We performed a meta-analysis of raw data and the inverse variance method, employing the standardized mean difference, of the age at menarche and BMI of adolescents. RESULTS: Participants totaled 1,718 from nine selected studies. The meta-analysis showed that the PCOS group had a higher BMI than the NPCOS group (SMD 0.334; CI95% 0.073 - 0.595; p = .012). The degree of heterogeneity of the studies was approximately 40%. No significant difference in age at menarche (SMD - 0.027; CI95% -0.227 - 0.172; p = 0.790) and menstrual patterns was found, but amenorrhea was described only in adolescents with PCOS. CONCLUSIONS: The main characteristic in menstrual pattern that differentiated PCOS patients from girls with HPO axis immaturity was amenorrhea. Also, the BMI of PCOS patients was nearly one third higher than that of adolescents with HPO axis immaturity.

RESUMO

BACKGROUND: Primary dysmenorrhea (PD) is an etiological cyclic pelvic pain related to the menstrual period; it can negatively impact women's quality of life and productivity. The aim of the present study was to estimate the prevalence of PD and analyze associated symptoms in Brazilian women. METHODS: An online cross-sectional study was carried out in Brazil, with a structured questionnaire regarding dysmenorrhea and associated symptoms. PD intensity was measured with the Numerical Rating Scale for Pain and classified as mild (1-3), moderate (4-7) and severe (> 8). The association between qualitative variables was performed using Pearson's Chi-Square Test. The quantification of this association was measured using multinomial logistic regression models, with calculation of Odds Ratio and confidence interval. A significance level of 5% was considered. RESULTS: A total of 10,070 women were included. Most participants classified PD intensity as moderate (40.4%, 41.9% and 49.7%) and severe (21.2%, 24.8% and 28.4%) in the previous month, 3 months and 5 years, respectively. The most common symptoms associated with PD were irritability, abdominal distension sensation, anxiety and feeling more emotional. The increased of the risk (OR > 1.0) for moderate and severe PD-related pain intensity is related to age, nulliparity and presence PD since adolescence. CONCLUSION: There is a high prevalence of PD among Brazilian women, and the most common symptoms reported were irritability, abdominal distension sensation, anxiety and feeling more emotional.

RESUMO

O objetivo foi apresentar uma síntese da literatura sobre o tema "pobreza menstrual". A busca incluiu as bases de dados PubMed/MEDLINE, LILACS, SCIELO Brasil e Google Scholar como fontes. Pares de pesquisadores conduziram a revisão de acordo com as diretrizes PRISMA e avaliaram a qualidade das evidências utilizando a ferramenta Mixed Methods Appraisal Tool. Um total de 2.457 publicações foram identificadas, das quais 22 foram incluídas na revisão. O conceito emergente desta revisão sugere que "pobreza menstrual corresponde a uma condição multidimensional, simbolicamente materializada pela falta de produtos de cuidado genital, refletindo principalmente a vulnerabilidade psicossocial de indivíduos que menstruam, decorrente da privação de acesso a bens fundamentais necessários para uma vida digna e respeitosa." A idade e as condições socioeconômicas são os principais marcadores de vulnerabilidade à "pobreza menstrual". Uma ampla gama de questões explora o tema, concentrando-se principalmente no acesso, custo e disponibilidade de produtos de higiene durante a menstruação. Ao sintetizar os conceitos e achados dos estudos incluídos nesta revisão, foi possível confirmar que fatores socioeconômicos desfavoráveis são os indicadores mais significativos da pobreza menstrual. Embora o fenômeno da pobreza menstrual se manifeste como privação de bens essenciais e falta de dignidade humana, os instrumentos de pesquisa e as soluções propostas têm se concentrado predominantemente no acesso e fornecimento de produtos de higiene. Esse foco restrito oferece visibilidade limitada às questões mais amplas de desigualdade e injustiça social que fundamentam a pobreza menstrual.

The objective was to present a synthesis of the literature on the topic 'menstrual poverty'. The search considered the sources PubMed/MEDLINE, LILACS, SCIELO Brazil and Google Scholar site. Pairs of researchers conducted the review steps according to the PRISMA guidelines, and assessed the quality of the evidence using the Mixed Methods Appraisal Tool. A total of 2,457 publications were identified, and 22 of them were included in the review. The concept outlined from this review suggests that "menstrual poverty corresponds to a multidimensional condition symbolically materialized by the lack of genital care products, which expresses, above all, the psychosocial vulnerability of the person who menstruates caused by the deprivation of the right to fundamental goods necessary for the enjoyment of a dignified and respectful life". Age and socioeconomic conditions are the main markers of vulnerability to 'period poverty'. A vast list of questions delves into the subject, primarily exploring aspects such as access, affordability, and availability of hygiene products to use during the menstrual flow period. By synthesizing the concepts and findings provided by the studies included in this review, it was possible to verify that the unfavorable socioeconomic factors are the most important makers of menstrual poverty. Although the menstrual poverty phenomenon is manifestation of essential goods deprivation and lack of human dignity, the research instruments and the solutions focused on access and supply of hygiene products. This reduction gives little visibility to the inequalities and social injustice that underlie the phenomenon of menstrual poverty.

RESUMO

ABSTRACT BACKGROUND AND OBJECTIVES: Premenstrual Syndrome (PMS) is a set of physical, mood, cognitive and behavioral changes which happens between the two weeks before menstruation, which can hinder a woman's personal, academic, and professional performance. The objective of this study was to identify the prevalence of PMS in female nursing students. METHODS: A cross-sectional study using a virtual questionnaire on sociodemographic and gynecological characteristics and the Premenstrual Symptoms Screening Tool (PSST) questionnaire, which looks for physical and psychological symptoms of PMS, interference of symptoms in daily life and establishes a positive screening for PMS. RESULTS: A total of 114 students participated in the study. The most prevalent characteristics were being between 18 and 23 years old, single and in their 5th or 6th academic year. In addition, the majority went through the menarche between 11 and 13 years of age, with menstrual flow of 3-5 days. Of these, 40.4% used hormonal contraceptive methods and 37.7% did not use any type of contraceptive method. The prevalence of PMS was 61.4%. The most frequent symptoms were physical symptoms (93.9%), anger/irritation (91.2%), urge to cry/increased sensitivity (88.6%), anxiety/tension (86.8%) and decreased interest in social activities (85.1%). These symptoms interfere with relationships with family (81.6%), social life activities (80.7%), efficiency at work or college/productivity (79.8%), relationships with colleagues at work/college (77.2%) and responsibilities at home (75.4%). CONCLUSION: PMS is prevalent among female nursing students and its symptoms affect the daily lives of this population, interfering with their personal and social relationships as well as academic activities.

RESUMO JUSTIFICATIVA E OBJETIVOS: A síndrome pré-menstrual (SPM) é um conjunto de alterações físicas, de humor, cognitivas e comportamentais, iniciadas entre as duas semanas prévias a menstruação, que podem causar desgastes no rendimento pessoal, acadêmico e profissional da mulher. O objetivo deste estudo foi identificar a prevalência da SPM em acadêmicas do curso de enfermagem. MÉTODOS: Estudo transversal realizado por meio de um questionário virtual sobre características sociodemográficas e ginecológicas e o questionário Premenstrual Symptoms Screening Tool (PSST), que busca sintomas físicos e psicológicos da SPM, interferência dos sintomas no cotidiano, e estabelece uma triagem positiva para SPM. RESULTADOS: Foram recrutadas 114 acadêmicas da graduação em enfermagem. As características mais prevalentes foram a faixa etária entre 18 e 23 anos, solteiras e cursando o 5° ou 6° período do curso. Ademais, a maioria com menarca entre 11 e 13 anos, com fluxo menstrual de 3 a 5 dias. Destas, 40,4% usavam métodos contraceptivos hormonais e 37,7% não usavam nenhum tipo de método contraceptivo. A prevalência encontrada de SPM foi de 61,4%. Os sintomas mais frequentes foram sintomas físicos (93,9%), raiva/irritação (91,2%), vontade de chorar/aumento da sensibilidade (88,6%), ansiedade/tensão (86,8%) e interesse diminuído nas atividades sociais (85,1%).

RESUMO

Background: Hemolacria or the presence of blood in tears is a rare condition, and there are only a few cases reported in the literature. Hemolacria is associated with multiple underlying diseases, including vicarious menstruation due to extragenital endometriosis. Case report: We present a 26-year-old woman with hemolacria and abdominal pain related to her menstrual cycle. The patient was diagnosed with bilateral ovarian endometriomas. After ruling out other possible causes of hemolacria, a progestin-only treatment was applied, with improvement of the abdominal pain and complete remission of hemolacria. Conclusions: When faced with hemolacria, a thorough anamnesis and physical examination must be performed, sometimes involving more than one specialist to reach a diagnosis. Considering hemolacria is a sign of a subjacent pathology, its treatment should be specific one for the disease in each case.

Antecedentes: La hemolacria o presencia de sangre en las lágrimas es una afección poco frecuente y sólo hay unos pocos casos descritos en la literatura. La hemolacria se asocia a múltiples enfermedades subyacentes, incluida la menstruación vicaria debida a endometriosis extragenital. Caso clínico: Presentamos a una mujer de 26 años con hemolacria y dolor abdominal relacionado con su ciclo menstrual. La paciente fue diagnosticada de endometriomas ováricos bilaterales. Tras descartar otras posibles causas de hemolacria, se aplicó un tratamiento sólo con progestágenos, con mejoría del dolor abdominal y remisión completa de la hemolacria. Conclusiones: Ante una hemolacria se debe realizar una anamnesis y exploración física minuciosa, en la que a veces interviene más de un especialista para llegar al diagnóstico. Teniendo en cuenta que la hemolacria es signo de una patología subyacente, su tratamiento debe ser el específico para la enfermedad en cada caso.

RESUMO

Objetivo: sintetizar la evidencia disponible relacionada con el acceso y las prácticas de higiene menstrual en América Latina y el Caribe. Método: revisión de alcance de la literatura con protocolo de investigación registrado en el Open Science Framework, realizada en las bases de datos bibliográficas: PubMed, Scopus, Web of Science y Portal Regional da Biblioteca Virtual em Saúde. Los datos fueron analizados mediante estadística descriptiva simple y análisis temático. Resultados: se incluyeron 15 publicaciones, la mayoría de las cuales trataban sobre adolescentes en Brasil: 12 artículos, dos informes técnicos y una monografía de trabajo de conclusión de curso. Como temas recurrentes en las publicaciones se destacan: acceso a condiciones dignas para el manejo de la higiene menstrual; necesidad de acceso a información sobre el manejo de la higiene menstrual; y prácticas para el manejo de la higiene menstrual. Conclusión: adolescentes informan dificultades para acceder a baños, agua y materiales absorbentes, y falta de información sobre la salud menstrual, incluso en las escuelas, lo que lleva al ausentismo escolar. De esta manera, las lagunas en la literatura científica latinoamericana revelan desigualdades y diversidad en las experiencias menstruales interseccionadas por categorías como género, clase social y etnia.

RESUMO

La creación de una vacuna para enfrentar la pandemia de COVID-19 conllevó un vacío de información sobre las posibles alteraciones del ciclo menstrual. El objetivo fue verificar las posibles alteraciones que se pudiesen haber generado en el ciclo menstrual de las mujeres posterior a la inoculación de la vacuna contra la COVID-19. Se realizó una revisión sistemática en las bases bibliografías Medline, Medline Complete, LILACS, CINAHL y ScIELO, utilizando los descriptores “Women”, “Woman”, “Fertile period”, “Vaccination”, “Mass vaccination”, “Immunization”, “COVID-19 vaccines”, “SARS-CoV-2 infection”, “COVID-19”, “Menstrual cycle”, “Menstruation”, “Endometrial cycle”, “Dysmenorrhea” y “Menstruation disturbances”. Mediante la utilización del protocolo PRISMA, de los 319 artículos localizados, 17 fueron incluidos en el análisis. La mayoría de los estudios incluyeron, principalmente, las vacunas Pfizer, Moderna, AstraZeneca y Johnson&Johnson/Janssen con una a tres dosis administradas. El porcentaje de ciclos menstruales alterados fue del 8,0% al 77,8%, y la alteración con mayor frecuencia referida fue la duración del ciclo menstrual, que fue desde 0,3 hasta 12 días de retraso de la menstruación. Todos los estudios refieren cambios en el ciclo menstrual con diversas prevalencias, con y sin significación estadística; sin embargo, también concluyen que estas alteraciones son reversibles y en un corto periodo de tiempo.

The creation of a vaccine to face the COVID-19 pandemic, led to an information gap on possible alterations of the menstrual cycle. The objective was to verify the possible alterations that could have been generated in the menstrual cycle of women, after the inoculation of the vaccine against COVID-19. A systematic review was carried out in the Medline, Medline Complete, LILACS, CINAHL and ScIELO bibliographic databases, using the descriptors “Women”, “Woman”, “Fertile period”, “Vaccination”, “Mass vaccination”, “Immunization”, “COVID-19 vaccines”, “SARS-CoV-2 infection”, “COVID-19”, “Menstrual cycle”, “Menstruation”, “Endometrial cycle”, “Dysmenorrhea” and “Menstruation disturbances”. Using the PRISMA protocol, of the 319 articles located, 17 were included in the analysis. Most of the studies mainly included the Pfizer, Moderna, AstraZeneca and Johnson&Johnson/Janssen vaccines with one to three doses administered. The percentage of altered menstrual cycles ranged from 8.0% to 77.8%, and the most frequently reported alteration was the length of the menstrual cycle, which occurred from 0.3 to 12 days late in menstruation. All the studies refer to changes in the menstrual cycle with different prevalences, with and without statistical significance; however, the same studies also conclude that these alterations are reversible and in a short period of time.

RESUMO

Objetivo: estabelecer as diferenças de sintomas físicos e mentais nos períodos menstrual e pré-menstrual em mulheres sedentárias. Métodos: estudo transversal, por questionário, respondido por 77 mulheres saudáveis, de 18 a 35 anos, sedentárias e que não fizessem uso de anticoncepcional continuamente. O questionário incluiu questões sobre dados antropométricos, sintomas físicos e mentais nos períodos menstrual e pré-menstrual. O teste Mann-Whitney comparou os momentos menstrual e pré-menstrual. Resultados: no período menstrual, em uma escala numérica de 0 a 10 pontos, observou-se maiores queixas de dor (7/10), mau humor (7/10), desânimo (8/10), irritabilidade (8/10), ansiedade (7/10), choro (7/10), raiva (9/10) e impacto nas atividades de vida diárias (AVDs) (7/10). Já no período pré-menstrual observou-se queixas de cefaleia (5/10), edema/retenção hídrica (6/10), mau humor (6/10), tristeza (6/10), irritabilidade (7/10), choro (7/10) e raiva (6/10). Quando comparados os períodos menstrual e pré-menstrual, o período menstrual apresentou piores sintomas de dismenorreia (P<0,05), lombalgia (P<0,05), dor nos membros inferiores (P<0,05), dificuldade de concentração (P<0,05), aumento do sono (P<0,05) e desânimo (P<0,05). As voluntárias apontaram 14 sintomas piores, com intensidade igual ou maior que 7 no período menstrual, e apresentaram 9 sintomas com intensidade igual ou maior que 7 no período pré-menstrual. Conclusão: os sintomas no período menstrual são mais intensos quando comparados ao período pré-menstrual e podem afetar AVDs. O presente estudo destaca a importância de análises e cuidados em relação ao período menstrual, já que tem grande impacto nos fatores físicos, mentais e emocionais das mulheres sedentárias.

Objective: to establish the differences in physical and mental symptoms in menstrual and premenstrual periods in sedentary women. Methods: cross-sectional study, through questionnaire, answered by 77 healthy women, aged 18 to 35 years, sedentary and who did not use contraceptives continuously. The questionnaire included questions about anthropometric data, physical and mental symptoms in menstrual and premenstrual periods. The Mann-Whitney test compared menstrual and premenstrual times. Results: in the menstrual period, on a numerical scale from 0 to 10 points, there were more complaints of pain (7/10), bad mood (7/10), discouragement (8/10), irritability (8/10), anxiety (7/10), crying (7/10), anger (9/10) and impact on ADLs (7/10). In the premenstrual period, there were complaints of headache (5/10), edema/water retention (6/10), bad mood (6/10), sadness (6/10), irritability (7/10), crying (7/10) and anger (6/10). When comparing the menstrual and premenstrual periods, the menstrual period had worse symptoms of dysmenorrhea (P<0.05), low back pain (P<0.05), pain in the lower limbs (P<0.05), difficulty concentrating (P<0.05), increased sleep (P<0.05) and discouragement (P<0.05). The volunteers reported 14 worse symptoms, with intensity equal to or greater than 7 in the menstrual period, and 9 symptoms with intensity equal to or greater than 7 in the premenstrual period. Conclusion: the symptoms in the menstrual period are more intense when compared to the pre-menstrual period and can affect the ADLs. This study highlights the importance of analysis and greater care in relation to the menstrual period, as it has a great impact on physical, mental and emotional factors in sedentary women.

RESUMO

OBJECTIVE: To describe menstrual cycle patterns in adolescents with concussion and investigate whether menstrual cycle phase at injury influenced postconcussion cycle pattern changes or concussion symptoms. STUDY DESIGN: Data were collected prospectively from patients aged 13-18 years presenting to a specialty care concussion clinic for an initial visit (≤28 days postconcussion) and, if clinically indicated, at a follow-up visit 3-4 months postinjury. Primary outcomes included menstrual cycle pattern change since injury (change/no change), menstrual cycle phase at time of injury (calculated using date of last period before injury), and symptom endorsement and severity, measured by Post-Concussion Symptom Inventory (PCSI). Fisher exact tests were used to determine the association between menstrual phase at injury and change in cycle pattern. Multiple linear regression was used to determine whether menstrual phase at injury was associated with PCSI endorsement and symptom severity, adjusting for age. RESULTS: Five hundred twelve postmenarchal adolescents were enrolled (age 15.2 ± 1.4 years), with 111 (21.7%) returning for follow-up at 3-4 months. Menstrual pattern change was reported by 4% of patients at initial visit and 10.8% of patients at follow-up. At 3-4 months, menstrual phase at injury was not associated with menstrual cycle changes (P = .40) but was associated with endorsement of concussion symptoms on the PCSI (P = .01). CONCLUSIONS: At 3-4 months' postconcussion, 1 in 10 adolescents experienced a change in menses. Menstrual cycle phase at injury was associated with postconcussion symptom endorsement. Leveraging a large sample of postconcussion menstrual patterns, this study represents foundational data regarding potential menstrual cycle effects of concussion in female adolescents.

RESUMO

PURPOSE: This study investigated the acute effect of anodal transcranial direct current stimulation (a-tDCS) over the left dorsolateral prefrontal cortex (DLPFC) on appetite, energy intake, food preferences, and mood states in the luteal and follicular phases of the menstrual cycle in women presenting premenstrual syndrome. METHODS: Sixteen women (26.5 ± 5.2 years; 1.63 ± 0.1 m; 64.2 ± 12.8 kg; body mass index 24.0 ± 5.0 kg/m2; body fat 27.6 ± 7.5%) with the eumenorrheic menstrual cycle were submitted to a-tDCS and sham-tDCS conditions over their follicular and luteal phases. At pre - and post-tDCS, hunger and desire to eat something tasty, (analogic visual scale), the profile of mood states (POMS), and the psychological components of food preferences (Leeds Food Preference Questionnaire-BR) were assessed. Participants recorded their food intake for the rest of the day using a diary log. RESULTS: There was a trend towards main effect of condition for decreased implicit wanting for low-fat savory food after a-tDCS but not sham-tDCS regardless of menstrual cycle phase (p = 0.062). There was no effect for self-reported hunger, desire to eat, energy and macronutrient intake, and on other components of food preferences (explicit liking and wanting for low- and high-fat savory and sweet foods, implicit wanting for low- and high-fat sweet and high-fat savory food); as well as for mood states. CONCLUSIONS: Although no significant effects of a-tDCS were found, the present investigation provides relevant perspectives for future studies.

RESUMO

Objetivo: Evaluar si la vacuna contra COVID-19 produce cambios en el patrón menstrual, tipo de cambio y dismenorrea. Métodos: Estudio observacional transversal. Se realizaron 6616 encuestas digitales a mujeres que recibieron vacuna contra COVID-19. Se aplicó encuesta vía redes y en consultas ginecológicas. Se calcularon desde tablas 2x2, porcentajes e intervalos de confianza del 95 %, se analizaron cambios menstruales en la muestra y en subgrupos según el tipo de vacuna, número de dosis, edad y residencia. Resultados: El 86,5 % (3535/4087) refirió cambios menstruales, siendo los más frecuentes: retraso menstrual (40,4 %) y sangrado menstrual más abundante (37,7 %). Hubo dismenorrea en 39 % acompañando cambios menstruales, y 2,1 % como único síntoma. Se observó diferencia estadísticamente significativa: 1) más cambios menstruales con mecanismo de acción vector viral chimpancé al compararse con virus inactivado; 2) vector viral humano y virus inactivado más cambios menstruales en el grupo de 18-34 años al compararse con 35-50 años y menos cambios al compararse con vector viral chimpancé en 35-50 años, y 3) ARNm fue el que menos se asoció con ausencia menstrual al compararse con vector viral humano 53 % y chimpancé 50 % más frecuente. Conclusión: Los cambios menstruales son muy frecuentes luego de vacunación contra COVID-19, estando esto en relación con el tipo de vacuna aplicada. Algunos mecanismos de acción parecen relacionarse con mayor o menor riesgo a cambios menstruales específicos(AU)

Objective: To evaluate if the COVID-19 vaccine produces changes in the menstrual pattern, type of change and dysmenorrhea. Methods: Observational and cross-sectional study. 6616 digital surveys were carried out on women who received a vaccine against COVID-19. A survey was applied via networks and in gynecological consultations. Percentages and 95 % confidence intervals were calculated from 2x2 tables, menstrual changes were analyzed in the sample and in subgroups according to type of vaccine, number of doses, age, and residence. Results: 86.5 % (3535/4087) reported menstrual changes, the most frequent being: menstrual delay (40.4 %) and heavier menstrual bleeding (37.7 %). Dysmenorrhea presented in 39 % accompanying menstrual changes, but 2.1 % as the only symptom. A statistically significant difference was observed: 1) more menstrual changes with mechanism of action chimpanzee viral vector when compared to inactivated virus, 2) human viral vector and inactivated virus more menstrual changes 18-34 years compared to 35-50 years and less changes when compared to chimpanzee viral vector in 35-50 years 3) mRNA was the least associated with menstrual absence when compared to human viral vector 53 % and chimpanzee 50 % more frequent. Conclusion: Menstrual changes are very common after vaccination against COVID-19, this being related to the type of vaccine administered. Some mechanisms of action seem to be related to a greater or lesser risk of specific menstrual changes(AU)

RESUMO

PURPOSE: Most women during their lifetime experience a combination of premenstrual syndrome (PMS) symptoms (eg, menstrual cramps) before and often to the end of menstruation. However, the impact of these symptoms on sport routines (eg, performance, training absence) during phases around menstruation is still unclear. Therefore, we investigated the impact of PMS symptoms on sport routines among nonelite athletes over 3 phases related to menstruation. METHODS: An online questionnaire was developed to recruit nonelite female athletes who participate in summer Olympic sports. Participants were allocated into 2 groups: those who experienced mild to moderate PMS symptoms (no-PMS) and those with severe PMS symptoms (p-PMS). Two hundred thirty-four responses from eumenorrheic women (p-PMS = 78%) were considered valid. An unpaired Student t test was conducted to compare demographic characteristics between groups and chi-square test to evaluate the impact of PMS status on sport routines between groups. RESULTS: A significant (P < .05) proportion of women in the p-PMS group changed their training schedule because of menstrual (55%) and premenstrual (61%) symptoms compared with the no-PMS group. Overall, all participants indicated that training (P = .01) and competitive (P < .01) performance are impacted during menstruation, followed by a greater impact (P < .05) in the p-PMS group before menstruation. CONCLUSION: The presence of PMS symptoms reduces training and competitive performance, primarily during and before menstruation, respectively. Severity of PMS symptoms was significantly associated with alterations in training schedule but not with competitive schedule.

RESUMO

Resumen OBJETIVO: Estimar la cantidad de pacientes con irregularidades menstruales que se embarazaron luego de una cirugía bariátrica (manga gástrica) y describir los desenlaces de los embarazos. MATERIALES Y MÉTODOS: Estudio retrospectivo de serie de casos de pacientes obesas y con irregularidades menstruales intervenidas mediante cirugía bariátrica (manga gástrica). Se operaron entre el 1 de junio de 2014 y el 31 de diciembre de 2019 en el Centro Médico Imbanaco Cali, Colombia. RESULTADOS: De 1418 cirugías bariátricas, tipo manga gástrica, 117 pacientes cumplieron con los criterios de inclusión, 80 de ellas se localizaron telefónicamente y aceptaron incluirse al estudio. Luego de la manga gástrica, el 86.25% (n = 69) de las pacientes logró la regularización de sus ciclos menstruales. Además, el 31% (n = 25) consiguió el embarazo, 80% (n = 20) de ellas tenían la intención de buscar el embarazo. Los desenlaces de esos embarazos fueron favorables, con partos a término, con adecuado peso y talla al nacer. CONCLUSIONES: Después de la cirugía bariátrica, tipo manga gástrica, en mujeres con irregularidades menstruales, 25 de las 80 pacientes se embarazaron y los desenlaces obstétricos fueron satisfactorios. Sin duda, hacen falta más estudios prospectivos para poder afirmar, con una mejor representación estadística, las repercusiones de la disminución del peso corporal en la tasa de fertilidad.

Abstract OBJECTIVE: To estimate the number of patients with menstrual irregularities who became pregnant after bariatric surgery (gastric sleeve) and to describe the pregnancy outcomes. MATERIALS AND METHODS: Retrospective study of a series of cases of obese patients with menstrual irregularities who underwent bariatric surgery (gastric sleeve). They were operated between June 1, 2014 and December 31, 2019 at the Imbanaco Cali Medical Center, Colombia. RESULTS: Of 1418 bariatric surgeries, gastric sleeve type, 117 patients met the inclusion criteria, 80 of them were located by telephone and agreed to be included in the study. After gastric sleeve, 86.25% (n = 69) of the patients achieved regularization of their menstrual cycles. In addition, 31% (n = 25) achieved pregnancy, 80% (n = 20) of them intended to seek pregnancy. The outcomes of these pregnancies were favorable, with full-term deliveries, with adequate weight and height at birth. CONCLUSIONS: After bariatric surgery, gastric sleeve type, in women with menstrual irregularities, 25 of the 80 patients became pregnant and the obstetric outcomes were satisfactory. Undoubtedly, more prospective studies are needed to be able to affirm, with a better statistical representation, the repercussions of the decrease in body weight on the fertility rate.

RESUMO

Abstract Objective To evaluate the continuation rates of the 52-mg levonorgestrel-releasing intrauterine system (LNG-IUS) during the first 5 years of use, reasons for its discontinuation, bleeding patterns, and new contraceptive choice after the 5th year, in adolescents and young women. Methods The present study was a 5-year prospective cohort conducted in a Family Planning Service of a tertiary hospital in Brazil. We selected 100 healthy women between 15 and 24 years old who used 52-mg LNG-IUS for contraception. The clinical follow-up of these women took place from June 2017 to December 2022. The study evaluated the continuation rates of the method, reasons for its discontinuation, bleeding patterns, and new contraceptive choice after the 5th year. Continuous data were reported as mean ± standard deviation (SD) and range (minimum-maximum). Categorical variables were described as percentages. Results The continuation rates of LNG-IUS were 89.1% (82/92), 82.9% (72/87), 75.3% (64/85), 70.5% (60/85), and 64.2% (54/84) in the 1st, 2nd, 3rd, 4th, and 5th years of use, respectively. The main reason for discontinuation was acne (11/30). Amenorrhea rates were 50, 54.1, 39, 35.7, and 51.8% at 12, 24, 36, 48, and 60 months, respectively. All patients who completed the study and needed contraception after the 5th year opted for long-acting contraceptive methods (LARC). Conclusion The LNG-IUS showed high continuation rates in adolescents and young women in the first 5 years of use. Most patients who completed the study chose a LARC method after the 5th year.

RESUMO

SUMMARY OBJECTIVE: This study aimed to comparatively evaluate the presence of abnormal uterine bleeding and associated factors among women from the five official Brazilian geographic regions. METHODS: This is a cross-sectional, population-based, multicenter study of reproductive-age women from the five regions of Brazil. All participants answered questionnaires containing personal and socioeconomic data and information on uterine bleeding (self-perception and objective data). RESULTS: A total of 1,761 Brazilian women were included, 724 from the Southeast, 408 from the Northeast, 221 from the South, 213 from the North, and 195 from the Central-West. Considering women's self-perception, the prevalence of abnormal uterine bleeding was 37.56% in the North region, 39.46% in the Northeast, 21.54% in the Central-West, 29.56% in the Southeast, and 25.34% in the South (p<0.001). Abnormal uterine bleeding was more prevalent in the North and Northeast, where women had lower purchasing power, became pregnant more often, and were the only ones financially responsible for supporting the family more often (p<0.001). The menstrual cycle lasted <24 days in less than 20% of the women in all regions (p=NS). Among these, approximately 8 out of 10 women had never undergone treatment in four out of the five regions evaluated. More than half of the evaluated women reported a worsening of their quality of life during bleeding. CONCLUSION: The prevalence of abnormal uterine bleeding in Brazilian women was higher in the North and Northeast, followed by the Southeast, South, and Central-West regions. There was a worsening of quality of life during menstruation regardless of the woman's self-perception of abnormal uterine bleeding. Such results can direct the actions of health managers toward a better approach to abnormal bleeding.

RESUMO

Resumen ANTECEDENTES: El tórax es la localización extrapélvica más frecuente de la endometriosis; esto sin que su incidencia se haya determinado con estudios suficientes. Tampoco se ha establecido del todo su fisiopatología, pero aun así se han planteado diversas teorías. El neumotórax catamenial es una de las posibles manifestaciones que hacen complejo establecer el diagnóstico e indicar un tratamiento. CASO CLÍNICO: Paciente de 31 años, con antecedente de neumotórax espontáneo a repetición, que acudió a consulta debido a disnea y dolor torácico de un mes de evolución. La radiografía de tórax evidenció el neumotórax del 50% en la parte derecha y la necesidad de la toracostomía. Puesto que los episodios de neumotórax ocurrían en fase catamenial, pero sin poder establecer una causa clara del cuadro clínico, se procedió a la toracoscopia diagnóstica con toma de muestra para estudio histopatológico. Durante el procedimiento se detectaron múltiples lesiones pseudonodulares, de aspecto inflamatorio crónico a nivel pleural y del parénquima pulmonar. El reporte histopatológico fue compatible con endometriosis pleuropulmonar; se le indicó terapia hormonal. Ante la evolución clínica satisfactoria y posoperatorio sin complicaciones la paciente fue dada de alta del hospital. CONCLUSIÓN: El neumotórax catamenial, como consecuencia de una endometriosis pleuropulmonar, es un diagnóstico realmente excepcional y su sospecha debe vincularse con el ciclo menstrual. La atención médica de las pacientes con este diagnóstico debe ser interdisciplinaria, no solo por las estrategias diagnósticas sino por la complejidad del tratamiento y su seguimiento. El tratamiento de elección suele requerir intervenciones quirúrgicas, sumadas a la indicación de la medicación hormonal para prevenir recurrencias, con tasas de éxito favorables. Están pendientes los estudios que establezcan la respuesta del tejido endometrial ectópico torácico al tratamiento médico.

Abstract BACKGROUND: The thorax is the most frequent extrapelvic location of endometriosis, although its incidence has not been sufficiently studied. Its pathophysiology has not been fully established, but several theories have been put forward. Catamenial pneumothorax is one of the possible manifestations that make it difficult to establish the diagnosis and indicate treatment. CLINICAL CASE: A 31-year-old female patient, with a history of repeated spontaneous pneumothorax, presented for consultation due to dyspnea and chest pain of one month of evolution. Chest X-ray showed a 50% pneumothorax on the right side and the need for thoracostomy. Since the episodes of pneumothorax occurred in catamenial phase, but without being able to establish a clear cause of the clinical picture, diagnostic thoracoscopy with sampling for histopathological study was performed. During the procedure multiple pseudonodular lesions of chronic inflammatory aspect were detected at pleural and lung parenchyma level. The histopathological report was compatible with pleuropulmonary endometriosis; hormonal therapy was indicated. Given the satisfactory clinical evolution and postoperative course without complications, the patient was discharged from the hospital. CONCLUSION: Catamenial pneumothorax, as a consequence of pleuropulmonary endometriosis, is a truly exceptional diagnosis and its suspicion should be linked to the menstrual cycle. The medical care of patients with this diagnosis should be interdisciplinary, not only because of the diagnostic strategies but also because of the complexity of the treatment and its follow-up. The treatment of choice usually requires surgical interventions, added to the indication of hormonal medication to prevent recurrences, with favorable success rates. Studies establishing the response of thoracic ectopic endometrial tissue to medical treatment are pending.
