Effectiveness and continuation rates of the etonogestrel-subdermal contraceptive implant versus short-acting contraceptive methods offered at no cost in Campinas, Brazil.

OBJECTIVES: To compare the efficacy, reasons for discontinuation and continuation rates of the etonogestrel (ENG)-subdermal contraceptive implant when offered at no cost, and the basis of free choice versus short-acting reversible contraceptive (SARC) methods including combined oral contraceptives (COCs), once-a-month injectables, vaginal ring, and patch. METHODS: We conducted a prospective study at the University of Campinas, Brazil, involving women aged 18 to 40 years. They were counseled on various contraceptive methods before entering the study and followed up every 3 months for up to 24 months. Satisfaction was assessed using a Likert scale. Survival rates were estimated using the Kaplan-Meier test, and curve comparisons were performed using the log-rank test. RESULTS: We enrolled 609 women including 358/609 women (58.8%) who chose the ENG-implant and 251/609 (41.2%) who chose SARC methods. Contraceptive failure and all other reasons for discontinuation were significantly higher in SARC users compared to the ENG-implant users (P < 0.001 and P = 0.002, respectively). The continuation rate was higher among ENG-implant users (89.9% and 75.4%) compared to SARC methods users (27.2% and 15.9%) up to 1 and 2 years after study initiation, respectively. Satisfaction was high in both groups (>82%). CONCLUSIONS: The ENG-implant showed higher contraceptive effectiveness and higher continuation rates than SARC methods up to 2 years after study initiation. Furthermore, users from both groups were highly satisfied with their contraceptive. The main reason for discontinuing use of the ENG-implant was bothersome uterine bleeding, while for SARC methods it was for personal reasons.

A Longitudinal Multilevel Analysis of the Effects of Contraceptive Failures on Unintended Pregnancies among Women in Urban Nigeria.

Unintended pregnancy is a global public health concern. However, the effect of contraceptive failure on unintended pregnancy remains unclear in Nigeria. We undertook a longitudinal analysis to examine the effect of contraceptive failure on unintended pregnancy among urban women in Nigeria. We used panel data from the Nigerian Urban Reproductive Health Initiative. The Measurement, Learning and Evaluation program conducted the surveys among a cohort of women aged 15-49 who were first interviewed at baseline in 2010/2011 and followed up at endline in 2014/2015. Analytic sample was 4140 women aged 15-49 who ever used contraceptives. We fitted three-level multilevel binary logistic regression models estimated with GLLAMM. The study established evidence that there is a significant effect of contraceptive failure on unintended pregnancy among urban women in Nigeria. The positive effect of between-person contraceptive failure indicates that respondents who experienced more contraceptive failure than the average in the sample had 5.26 times higher odds of unintended pregnancy (OR = 5.26; p-value < 0.001). Results also established a significant effect of within-person contraceptive failures among the respondents. Findings suggest there is evidence of a significant longitudinal effect of contraceptive failure on unintended pregnancy in urban Nigeria. Efforts to reduce unintended pregnancy must include interventions to address the problem of contraceptive failure among urban women in Nigeria.

Uma revisão integrativa a respeito de métodos contraceptivos / An integrative review on contraceptive methods / Una revisión integrativa de los métodos anticonceptivos

Os métodos contraceptivos desempenham um papel vital na saúde sexual e reprodutiva, oferecendo opções que permitem o planejamento familiar e a prevenção de gravidezes indesejadas. Este artigo busca descrever os benefícios e desvantagens dos principais anticoncepcionais presentes na atualidade por meio de uma revisão integrativa da literatura, que buscou identificar os achados científicos publicados nos últimos 10 anos (2013 a fevereiro de 2023). A seleção de artigos foi feita nas bases eletrônicas de dados da PubMed, BVS, SciELO e no Google Acadêmico. Para a realização da revisão integrativa foi estabelecida a pergunta norteadora, para possibilitar a busca na base dados: Quais os benefícios e as desvantagens dos anticoncepcionais adesivo combinado, anel vaginal, sistema intrauterino de liberação de Levonorgestrel (SIU-LNG), contracepção de emergência (pílula de emergência), implante hormonal e anticoncepcional oral (ACO). Um dos pontos mais notáveis nesta revisão foi a grande variedade de métodos contraceptivos e suas peculiaridades, que se adequam à necessidade da usuária, sendo, portanto, preciso uma análise cuidadosa do método a ser escolhido. Outro ponto de destaque, foi que apesar dos benefícios dos contraceptivos, também estão presentes os efeitos adversos e possíveis complicações, além das precauções em sua utilização.

Contraceptive methods play a vital role in sexual and reproductive health, offering options that allow for family planning and the prevention of unwanted pregnancies. This article seeks to describe the benefits and disadvantages of the main contraceptives currently available through an integrative literature review, which sought to identify scientific findings published in the last 10 years (2013 to February 2023). The selection of articles was made in the electronic databases of PubMed, VHL, SciELO and Google Scholar. To carry out the integrative review, the guiding question was established, to enable the search in the database: What are the benefits and disadvantages of contraceptives combined patch, vaginal ring, Levonorgestrel-releasing intrauterine system (LNG-IUS), emergency contraception (emergency pill), hormonal implant and oral contraceptive (OC). One of the most notable points in this review was the wide variety of contraceptive methods and their peculiarities, which adapt to the user's needs, therefore requiring a careful analysis of the method to be chosen. Another highlight was that despite the benefits of contraceptives, adverse effects and possible complications are also present, in addition to precautions in their use.

Los métodos anticonceptivos desempeñan un papel vital en la salud sexual y reproductiva, ofreciendo opciones que permiten la planificación familiar y la prevención de embarazos no deseados. Este artículo busca describir los beneficios y desventajas de los principales anticonceptivos actualmente disponibles a través de una revisión integrativa de la literatura, que buscó identificar hallazgos científicos publicados en los últimos 10 años (2013 a febrero de 2023).

Uno de los puntos más destacables de esta revisión fue la gran variedade de métodos anticonceptivos y sus peculiaridades, que se adaptan a las necesidades del usuario, requiriendo por tanto un análisis cuidadoso del método a elegir. Otro destaque fue que a pesar de los beneficios de los anticonceptivos, también están presentes efectos adversos y posibles complicaciones, además de precauciones en su uso.

Representações sociais sobre maternidade na reprodução humana assistida: discursos de mulheres inférteis / Social representations of motherhood in assisted human reproduction: discourses of infertile women / Representaciones sociales de la maternidad en la reproducción humana asistida: relatos de mujeres infértiles

Este trabalho tem o objetivo de analisar as concepções de maternidade para mulheres inférteis de diferentes níveis socioeconômicos que estão em tratamento de reprodução assistida. Trata-se de um estudo qualitativo, descritivo, que utilizou como instrumento uma entrevista semiestruturada e contemplou temas como o significado de família, desejo/expectativas sobre filho e gestação e expectativas sobre a maternidade. Participaram da pesquisa 48 mulheres inférteis acima de 35 anos que usam tecnologias de reprodução assistida de alta complexidade em instituições privada e pública. Os dados foram tratados pela análise de conteúdo em que emergiram os temas: representações sociais da família; representações sociais da maternidade; expectativas com a gestação e os modelos maternos; e o filho imaginado. As participantes representaram a família de forma positiva, como um sistema de suporte, de fundação e origem de amor, configurando-a como um laço social. Por outro lado, as concepções de família com base na consanguinidade também estiveram presentes, representando a família pela perpetuação da espécie e pela importância do laço biológico. A maternidade foi marcada por significativa idealização, sendo vista como um papel gratificante e de realização da feminilidade. O peso da cobrança social para procriar também foi sentido como um dever a cumprir e que, na impossibilidade de se realizar, gera sentimentos de inferioridade, menos-valia, impotência e inadequação perante a sociedade, o que reforça o estigma da infertilidade. Tais resultados apontam a importância de reflexões sobre o papel da mulher na nossa cultura, visto que a maternidade é ainda utilizada como medida para o sucesso ou fracasso feminino. Faz-se necessário também refletir sobre a possibilidade da maior inserção do trabalho psicológico na reprodução assistida, visto a carga emocional e social envolvidas nesse processo.(AU)

This study aimed to analyze the conceptions of motherhood for infertile women from different socioeconomic levels who are undergoing assisted reproduction treatment. This is a qualitative and descriptive study that used a semi-structured interview as an instrument and included topics such as the meaning of family and desires/expectations about the child, pregnancy, and motherhood. A total of 48 infertile women over 35 years of ages using high-complexity assisted reproductive technologies in private and public institutions participated in this research. The data were treated by content analysis in which the following themes emerged: family social representations; social representations of motherhood; expectations with pregnancy and maternal models; and the imagined son. Participants represented the family in a positive way as a support system and the foundation and origin of love, embracing the family as a social bond. On the other hand, the family concepts based on inbreeding were also present, representing the family by perpetuation of the species and the importance of biological bonds. Motherhood was marked by significant idealization, being seen as a gratifying role and the fulfillment of femininity. The weight of the social demand to procreate was also felt as a duty to be fulfilled that, in the impossibility of carrying it out, generates feelings of inferiority, worthlessness, impotence, and inadequacy toward society, which reinforce the stigma of infertility. Results point to the necessary reflections on the role of women and our culture since Motherhood is still used as a measure of female success or failure. They also point to a reflection on the possibility of greater inclusion of psychological work in assisted reproduction given the emotional and social burden involved in this process.(AU)

Este estudio tuvo como objetivo analizar las concepciones de maternidad de mujeres infértiles, de diferentes niveles socioeconómicos, que se encuentran en tratamiento de reproducción asistida. Se trata de un estudio cualitativo, descriptivo, que utilizó como instrumento una entrevista semiestructurada e incluyó temas como el sentido de la familia, deseos/expectativas sobre el hijo y el embarazo y expectativas sobre la maternidad. Participaron en la investigación un total de 48 mujeres infértiles, mayores de 35 años, usuarias de tecnologías de reproducción asistida de alta complejidad en instituciones públicas y privadas. Los datos se sometieron a análisis de contenido del cual surgieron los temas: representaciones sociales familiares; representaciones sociales de la maternidad; expectativas con el embarazo y modelos maternos; hijo imaginado. Las participantes representaron a la familia de manera positiva, como sistema de apoyo, fundamento y origen del amor, configurándola como vínculo social. Por otro lado, también estuvieron presentes las concepciones familiares basadas en la consanguinidad, representando a la familia para la perpetuación de la especie y la importancia del vínculo biológico. La maternidad estuvo marcada por una importante idealización, vista como un rol gratificante y de realización de la feminidad. También se sintió el peso de la demanda social de procrear como un deber que cumplir y que, ante la imposibilidad de realizarlo, genera sentimientos de inferioridad, desvalorización, impotencia e inadecuación en la sociedad, lo que refuerza el estigma de la infertilidad. Por tanto, son necesarias reflexiones sobre el papel de la mujer en nuestra cultura, ya que la maternidad se sigue utilizando como medida del éxito o fracaso femenino. También se reflexiona sobre la posibilidad de una mayor inclusión del trabajo psicológico en la reproducción asistida dada la carga emocional y social que implica este proceso.(AU)

Eficacia y seguridad del uso extendido de anticonceptivos orales combinados / Efficacy and safety of extended use of combined oral contraceptives

Los anticonceptivos orales combinados constituyen hoy en día uno de los métodos anticonceptivos más populares a nivel mundial. Su composición consiste en una combinación de análogos de hormonas sexuales femeninas que se administran en bajas dosis diarias, manteniendo constante su concentración sanguínea y evitando de esta forma los cambios en el eje endócrino que estimulan la ovulación. Con el objetivo de recrear los procesos fisiológicos, la mayoría de las formulaciones comprenden un intervalo de 4 a 7 días libres de hormonas en el cual se genera el sangrado por deprivación.A partir de una viñeta clínica en la que una paciente sana desea posponer su hemorragia por deprivación, y tras realizar una búsqueda bibliográfica que prioriza las investigaciones más recientes y de mejor calidad, la autora revisa la evidencia sobre el uso de hormonas sin intervalo libre, especialmente su efectos sobre la eficacia y la incidencia de efectos adversos. (AU)

Nowadays, combined oral contraceptives are one of the most popular contraceptive methods worldwide. Its composition consists of a combination of similar female sex hormones administered in low daily doses, keeping their blood concentration constant and thus avoiding changes in the endocrine axis that stimulate ovulation. In order to recreate physiological processes, most formulations include an interval of 4 to 7 hormone-free days in which withdrawal bleeding occurs.Starting from a clinical vignette in which a healthy patient desires to postpone her withdrawal bleeding, and after conducting a bibliographic search that prioritizes the most recent and best-quality research, the author reviews the evidence about the use of hormones without free interval, especially their effects on efficacy and the incidence of adverse effects.

O uso dos métodos anticoncepcionais por estudantes de Medicina: uma revisão narrativa / Medical students' use of contraceptive methods: a narrative review

Anticoncepção são todas as técnicas e métodos utilizados para evitar a concepção. Os estudantes de Medicina se destacam nesse contexto, por representarem uma população em um período no qual a gravidez e doenças sexualmente transmissíveis são emergenciais. Logo, este estudo analisou a eficácia dos métodos contraceptivos na comunidade acadêmica médica e verificou se há ou não diferença na taxa de eficácia, em comparação com a população em geral. Sendo assim, realizou- -se uma revisão narrativa e encontraram-se 2.182 artigos; desses, 1.513 cumpriram o critério de inclusão, porém somente quatro artigos atendiam a todos os critérios e foram utilizados. A conclusão do estudo foi de que a taxa de Pearl é maior na população estudada devido ao mau uso dos contraceptivos, necessitando da melhora na qualidade da educação sexual nas universidades de Medicina ao redor do mundo, a fim de se evitarem a perpetuação da má utilização de contraceptivos e a desinformação no meio acadêmico médico.

Contraception is all the techniques and methods that are used to prevent conception. Medical students stand out in this context because they represent a population in a period in which pregnancy and sexually transmitted diseases are emergencies. Therefore, this study analyzed the effectiveness of contraceptive methods in the medical academic community and verified whether or not there is difference in the rate of effectiveness compared to the general population. A narrative review was conducted and 2,182 articles were found, of these 1,513 met the inclusion criteria, but only four articles met all the criteria and were used. The conclusion of the study was that Pearl's rate is lower in the studied population due to the misuse of contraceptives, requiring improvement in the quality of sex education in medical universities around the world in order to avoid perpetuation of misuse of contraceptives and misinformation in the medical academic environment.

Métodos anticonceptivos de larga duración (LARC): características de las usuarias, tasa de continuidad y efectividad / Long-Acting Reversible Contraceptive (LARC) methods: User characteristics, effectiveness, and continuation rates

Antecedentes: Los métodos anticonceptivos reversibles de larga duración (LARC) proporcionan una anticoncepción larga y reversible. Incluyen dispositivos intrauterinos (DIU) e implantes subdérmicos. Material y métodos: Estudio observacional longitudinal retrospectivo desde enero de 2017 a diciembre de 2019 incluyendo usuarias de LARC del Departamento de Salud de Elche. Se realizaron análisis descriptivos de: características de las pacientes, complicaciones postinserción, efectos no deseados y motivo de abandono, utilizando Kruskal-Wallis, ANOVA o chi-cuadrado en los análisis comparativos según la variable. Se analizaron las probabilidades de abandono tras 18meses mediante curvas Kaplan-Meier y se compararon mediante test Log-Rank. Se evaluó la razón de riesgo de las alteraciones del patrón de sangrado en las probabilidades de abandono mediante modelo de riesgos proporcionales de Cox. Resultados: Se incluyeron 605 usuarias de LARC, generalmente de raza blanca, multíparas y con pareja sexual estable. Las complicaciones más observadas fueron expulsión del DIU (4%) y hematoma cutáneo en la zona de inserción del implante (42,1%). El efecto no deseado más notificado fue el cambio del patrón de sangrado (26,8%) y su aparición aumentó el riesgo de interrupción del método (HR=1,76; IC95%: 1,15-2,68). Tras 18meses de uso, la tasa de continuidad fue del 86,9% (mayor para DIU-LNG 52mg) y la efectividad fue del 99,60% (resultado de 2embarazos con el uso de DIU-Cu). Conclusiones: Dado que los LARC son los métodos anticonceptivos reversibles más efectivos y con mayores tasas de continuación, deberían ser los métodos de primera línea ofrecidos a todas las mujeres que no presenten contraindicaciones.(AU)

Background: Long-Acting Reversible Contraceptive (LARC) methods provide long and reversible contraceptive effects. They include intrauterine devices (IUDs) —copper-containing IUD or levonorgestrel-releasing IUDs— and subdermal implant. Material and methods: A longitudinal observational retrospective study between January 2017 and December 2019 in which clinical records of users of LARC methods of the Elche Health Department were reviewed. Descriptive analyses were performed to describe user characteristics, post insertion problems, unwanted effects, and reasons for discontinuation; Kruskal-Wallis, ANOVA, and Chi-square were performed to compare these variables among different LARC methods, where appropriate. Kaplan-Meier survival curves were constructed to estimate continuation rates and the logrank test was applied for statistical comparisons. Cox proportional hazard models were used to estimate the hazard ratio (HR) for risk of contraceptive method discontinuation due to abnormal bleeding patterns. Results: Were included 605 LARC method users. These women were generally white, multiparous, and in stable relationships. The most common complications were IUD expulsion (4%) and haematoma at the implant site (42.1%). The main side effect was a change in bleeding patterns (26.8%) and was associated with premature removal (HR=1.76; 95%CI: 1.15-2.68). After 18months of use, the continuation rate was 86.9% (significantly higher for LNG-IUD 52mg) and effectiveness was 99.60% (result of 2 unintended pregnancies with use of copper-containing IUDs). Conclusions: Given that LARC methods have the highest rates of contraceptive efficacy and continuation, these methods should be the first-line contraceptive methods offered to patients without contraindications.(AU)

Factors Associated with Failed Contraception in Women Attending Level One Hospitals in Lusaka, Zambia

Background: Unintended pregnancy is a major public health concern due to its impact on maternal morbidity and mortality. Contraceptive failure is one of the causes of unintended pregnancy. Data on factors associated with contraceptive method failure is scarce. This study therefore aimed to explore factors associated with contraceptive failure. Methodology: Unmatched case-control study was conducted at five Level One Hospitals in Lusaka. Convenience sampling was used to enrol 108 cases for whom pregnancy occurred while on a modern contraceptive method and 108 hospital-based controls who were on a modern contraceptive method and not pregnant. Binary and multiple logistic regressions were utilized for assessment of factors associated with failed contraception. Results: Among the 108 cases, 46 (42.6%), 40 (37%), 17 (15.7%) and 1 (0.9%) were on the oral contraceptive pill, injectable, implant and intrauterine device contraception methods respectively while 2 (1.9%) were on barrier and emergency contraceptive methods respectively. The odds of contraceptive failure when using the oral contraceptive pill was more than 7 times (AOR 7.790, 95% CI 1.210-50.161, p=0.031). Those who had contraception failure were more than 3 times more likely to be younger than 30 years old compared to those whose contraceptive method did not fail (AOR 3.559, 95% CI 1.100-11.521, p=0.034 and AOR 3.596, 95% CI 1.354-9.550, p=0.010 respectively for age groups 18-24 years and 24-30 years old). Other factors associated with higher odds of contraceptive failure were duration of marriage greater than one year, with the highest odds in those married for more than 10 years (AOR 9.744, 95% CI 2.232-42.537, p=0.002), higher social support (AOR 2.402, 95% CI 1.085-5.321, p=0.031), multiparity (AOR 15.299, 95% CI 3.034- 77.151, p=0.001), and duration of use of antecedent contraception method of more than 2-3 years (AOR 4.913, 95% CI 1.662-14.526, p=0.004). Conclusion: The oral contraceptive pill, younger age, marriage duration of more than one year and contraceptive use more than three years were associated with contraceptive failure. Good messaging and counseling on usage of the oral contraceptive pill are recommended.

Aconselhamento contraceptivo para o paciente transgênero designado mulher ao nascimento / Contraceptive counseling for the transgender patient designated female at birth

Apesar de 0,7% da popul ação brasileira se identificar como transgênero, não existe treinamento para que o profissional de saúde realize um acolhimento de maneira integral a esse paciente, incluindo a discussão do planejamento reprodutivo. O uso de testosterona promove amenorreia nos primeiros meses de uso, entretanto esse efeito não garante eficácia contraceptiva e, consequentemente, aumenta os riscos de uma gravidez não planejada. Trata-se de uma revisão integrativa com o objetivo de avaliar e organizar uma abordagem do aconselhamento contraceptivo na população transgênero que foi designada mulher ao nascimento. Realizou-se busca estratégica em PubMed e Embase, bem como em guidelines internacionais, sobre cuidados à população transgênera. De 88 artigos, 11 foram utilizados para desenvolver o modelo de aconselhamento contraceptivo. O modelo segue as seguintes etapas: (1) Abordagem das informações relacionadas à necessidade de contracepção; (2) Avaliação das contraindicações ao uso dos métodos contraceptivos (hormonais e não hormonais); (3) Efeitos colaterais e possíveis desconfortos associados ao uso do contraceptivo. O modelo de aconselhamento contraceptivo é composto de 20 questões que abordam as indicações e contraindicações ao uso desses métodos e um fluxograma que auxilia na escolha entre os métodos permitidos ao paciente de acordo com a sua necessidade.(AU)

Cambios en el uso de anticonceptivos, embarazos no planificados e hijos en adolescentes chilenas entre 1997 y 2018 / Changes in the use of contraceptives, unplanned pregnancies and children in Chilean adolescents between 1997 and 2018

INTRODUCCIÓN: El embarazo en las adolescentes ha persistido como un problema de salud pública y social en Chile, afectando a las adolescentes más vulnerables y reflejando las desigualdades. OBJETIVO: Describir los cambios en el uso de anticonceptivos, embarazos no planificados e hijos en adolescentes chilenas entre 1997 y 2018. MÉTODO: Estudio ecológico de series temporales entre los años 1997 y 2018. Se midió la asociación entre variables sociodemográficas y efectividad del método anticonceptivo para los años 2006 y 2018, mediante la prueba estadística de Rao-Scott. Se estimaron tendencias del porcentaje de uso de métodos anticonceptivos según su eficacia y presencia de embarazos no planificados e hijos con modelos de regresión lineal (método de Prais-Winsten). RESULTADOS: Se observó un aumento en la frecuencia de adolescentes sexualmente activas y en el uso de anticonceptivos, especialmente píldoras e inyectables. La serie temporal de uso de anticonceptivos fue no estacionaria, la tendencia fue creciente (coeficiente: 4,59; intervalo de confianza del 95% [IC95%]: 3,43-5,74; p = 0,001), aumentando 4,59% cada 3 años. Las series de embarazos no planificados y tener hijos fueron series temporales no estacionarias y ambas presentaron una tendencia decreciente (coeficiente: −4,78; IC95%: −6,32 a −3,24; p = 0,002; y coeficiente: −3,93; IC95%: −6,18 a −1,68; p = 0,008), disminuyendo un 4,78% y un 3,93%, respectivamente, cada 3 años. CONCLUSIONES: El aumento en el uso de anticonceptivos en adolescentes ha ido unido a una importante disminución en los embarazos no planificados y los hijos en esta población.

INTRODUCTION: Adolescent pregnancy has persisted as a public and social health problem in Chile, affecting the most vulnerable adolescents and reflecting inequalities. OBJECTIVE: To describe the changes in the use of contraceptives, unplanned pregnancies and children in Chilean adolescents between 1997 and 2018. METHOD: Ecological study of time series between the years 1997 and 2018. The association between sociodemographic variables and the effectiveness of the contraceptive method for the years 2006 and 2018 was measured using the Rao-Scott statistical test. Trends in the percentage of use of contraceptive methods were estimated according to their efficacy and presence of unplanned pregnancies and children with linear regression models (Prais-Winsten method). RESULTS: An increase in the frequency of sexually active adolescents and the use of contraceptives, especially pills and injectables, was observed. The time series of contraceptive use was non-stationary, the trend was increasing (coefficient: 4.59; 95% confidence interval [95% CI]: 3.43-5.74; p = 0.001), increasing 4.59% every three years. The time series, unplanned pregnancies and having children were non-stationary time series, both showed a decreasing trend (coefficient: −4.78; 95%CI: −6.32 to −3.24; p = 0.002; and coefficient: −3.93; 95% CI: −6.18 to −1.68; p = 0.008), decreasing 4.78% and 3.93%, respectively, every 3 years. CONCLUSIONS: The increase in the use of contraceptives in adolescents has been linked to a significant decrease in unplanned pregnancies and children in this population.

El defecto inherente del endometrio causa fallo de implantación en Técnica de Reproducción Asistida / Inherent defect of the endometrium causes implantation failure in Assisted Reproductive Technique

Introduction. Implantation failure appears to be a significant factor in Assisted reproductive technique (ART) procedures. Even a mature endometrium may be non-receptive, preventing implantation or rejection of implanted embryo in early months of pregnancy, resulting in miscarriage or unexplained infertility with or without other associated factors. Objective. To investigate causes of failed implantation inspite of uneventful Grade I embryo transfer in ART procedure Material and Method. 90 women aged range between 25-40 yr old who visited Department of Reproductive Medicine at Calcutta Fertility Mission, over a period of 24 months(January 2017 to December 2019) , satisfying the inclusion criteria, were enrolled in this observational study. Endometrial aspirate histopathology was done along with ∞5ß3 integrin expression. They were treated with natural micronized progesterone (NMP) or oral dydrogesterone and results of endometrial changes were statistically analyzed. Results. 28.89% and 31.11% of women were seen to have mid-secretory changes of the endometrium after being treated with NMP and dydrogesterone respectively. Integrins were expressed in only 59.26% of women with mid-secretory endometrium and 5.41% of early secretory endometrium, which was statistically significant (p value <0.001). Conclusion. About 70% patients even after treatment with estrogen and progestin did not have adequate response in endometrial maturation. Not all patients with mid-secretory endometrium had integrin positive, when tested. NMP and oral Dydrogesterone have similar effect in endometrial maturation as well as in yielding successful pregnancy in some patients with previously failed In-vitro fertilization embryo transfer (IVF-ET).

Remoção histeroscópica de sistema intrauterino em gestação inicial: revisão de literatura / Hysteroscopic removal of the intrauterine system in early pregnancy: a literature review

Os dispositivos intrauterinos (DIUs) são os métodos contraceptivos reversíveis de longa duração mais utilizados no mundo, apresentando altas taxas de eficácia e segurança. Na presença de gestação, o DIU pode ser retirado com uma leve tração dos fios, quando visíveis. Na impossibilidade de visualização dos fios, há a opção de retirada por histeroscopia, que tem se mostrado segura e eficaz para a retirada de DIU retido na cavidade. Foram pesquisados os termos: "intrauterine device", "pregnancy" e "hysteroscopy". Dos 378 artigos encontrados, foram selecionados 18 artigos que cumpriam os objetivos desta revisão. A presença de DIU durante a gestação se mostra um fator de risco independente para desfechos desfavoráveis como abortamento, corioamnionite, parto prematuro e maior taxa de admissão em unidade de terapia intensiva neonatal. A histeroscopia ambulatorial se mostra uma alternativa segura e eficaz na retirada do DIU no primeiro trimestre.(AU)

Intrauterine devices (IUDs) are the most widely used reversible contraceptive methods in the world, with high rates of efficacy and safety. In the presence of pregnancy, the IUD can be removed by gently traction of the threads, when visible. If the wires cannot be visualized, we have the option of hysteroscopy removal, which has been shown to be safe and effective for the removal of an IUD retained in the cavity. The terms "intrauterine device", "pregnancy" and "hysteroscopy" were searched. Of the 378 articles found, 18 articles were selected that met the objectives of this review. The presence of IUDs during pregnancy is an independent risk factor for unfavorable outcomes such as abortion, chorioamnionitis, premature birth and a higher rate of admission to a neonatal intensive care unit. Ambulatory hysteroscopy is a safe and effective alternative for IUD removal in the first trimester.(AU)

Indications and reasons for discontinuing the levonorgestrel-releasing intrauterine system (LNG-IUS) / Indicações e razões para descontinuação do sistema intra-uterino liberador de levanogestrel (SIU-LNG)

Abstract Objectives: to identify the main indications and reasons for discontinuing the use of the Levonorgestrel-Releasing Intrauterine System (LNG-IUS). Methods: a cross-sectional study was carried out from medical records of 327 women who used the LNG-IUS 52mg between January 2011 and December 2016 at a public hospital in the Northeast of Brazil. Results: the main indications for the use of the LNG-IUS were: contraception (32.7%), myoma/metrorrhagia (28.7%) and endometriosis/pelvic pain (22.3%). Of the 327 women, 68 (20.8%) had discontinued using the device. The most frequent reasons for discontinuation were: expulsion (9.2%), LNG-IUS expiration (3.7%), bleeding (2.4%) and pain (1.5%). Most patients had no difficulty in the insertion and did not require anesthesia/sedation. Among the 30 women who expelled the device, 17 (56.7%) had used it for metrorrhagia and myoma, 8 (26.7%) for contraception, and 5 (16.6%) for endometriosis/pelvic pain. Conclusions: the LNG-IUS is a well-accepted contraceptive method, with therapeutic applications for some gynecological conditions and a low expulsion rate.

Resumo Objetivos: identificar as principais indicações e razões para a descontinuação do uso do sistema intra-uterino liberador de levanogestrel (SIU-LNG). Métodos: foi realizado um estudo transversal a partir de prontuários de 327 mulheres que usaram o SIU-LNG 52mg entre janeiro de 2011 e dezembro de 2016 em um hospital público do Nordeste do Brasil. Resultados: as principais indicações para o uso do SIU-LNG foram: contracepção (32,7%), mioma / metrorragia (28,7%) e endometriose / dor pélvica (22,3%). Das 327 mulheres, 68 (20,8%) haviam descontinuado o uso do dispositivo. Os motivos mais frequentes de descontinuação foram: expulsão (9,2%), expiração de SIU-LNG (3,7%), sangramento (2,4%) e dor (1,5%). Conclusão: a maioria dos pacientes não teve dificuldade na inserção e não necessitou de anestesia / sedação. Entre as 30 mulheres que expulsaram o dispositivo, 17 (56,7%) o utilizaram para metrorragia e mioma, 8 (26,7%) para contracepção e 5 (16,6%) para endometriose / dor pélvica.

Efectividad de las intervenciones educativas para la prevención del embarazo en la adolescencia / Effectiveness of educational interventions for the prevention of pregnancy in adolescents

Objetivo: Evaluar la efectividad de las intervenciones educativas dirigidas a prevenir el embarazo en la adolescencia. Diseño: Revisión sistemática. Fuentes de datos: Se consultaron las bases de datos PubMed, CINAHL, Scopus, Cuiden Plus, LILACS e IME para buscar estudios sobre intervenciones educativas para la prevención del embarazo en la adolescencia. Selección de estudios: Se seleccionaron un total de 24 investigaciones primarias, donde se evaluaba el efecto de un programa educativo para la prevención del embarazo en la adolescencia. La calidad de los estudios seleccionados se evaluó usando la escala CASPe. Resultados: Los programas educativos que midieron una modificación de la tasa de embarazo en la adolescencia muestran resultados poco concluyentes, ya que 2 investigaciones obtienen una reducción y otros 2 no hallan cambios significativos. Sin embargo, los programas educativos se muestran efectivos para aumentar el nivel de conocimiento sobre sexualidad y métodos anticonceptivos, y para modificar las actitudes sobre el riesgo de embarazo en la adolescencia o las actitudes hacia el uso de los métodos anticonceptivos. No se encuentran diferencias estadísticamente significativas entre los estudios que muestran un resultado positivo y los estudios con resultado negativo (p > 0,05) para ninguno de los resultados analizados en la revisión. Conclusión: No existe una modalidad de intervención que sea la más efectiva para la prevención de un embarazo en la adolescencia. Se necesita un mayor número de investigaciones con un abordaje longitudinal que valoren no solo resultados intermedios, sino una modificación en la tasa de embarazo

Objective: To assess the effectiveness of the interventions to prevent a pregnancy in adolescence. Design: Systematic review. Data sources: The following databases were consulted: PubMed, CINAHL, Scopus, Cuiden Plus, LILACS, and IME, in order to identify interventions aimed at preventing a pregnancy in adolescence. Study selection: A total of 24 primary investigations, in which an educational program to prevent a pregnancy in the adolescence was evaluated, were selected. The quality of the selected studies was assessed according to the CASPe scale. Results: Educational programs for the modification of the teenage pregnancy rate show inconclusive results, as there are 2 studies that find a reduction, and 2 that find that there are no significant changes. For secondary outcomes, it was found that educational programs are effective for increasing the knowledge level about sexuality and contraceptive methods and changing attitudes about the risk of a teenage pregnancy or the use of contraceptive methods. There are no statistically significant differences between the studies with a positive and negative outcome (P > .05) for any of the results analysed in this review. Conclusion: There is no a single intervention modality that is the most effective for prevention of a teenage pregnancy. More research is needed with a longitudinal approach that assess not only intermediate results, but also a modification in the pregnancy rate

O uso da pílula anticoncepcional e as alterações das principais vias metabólicas / The use of contraceptive pill and alterations of main metabolic pathways

As pílulas anticoncepcionais são esteroides que visam impedir a gravidez indesejada e regular distúrbios menstruais. Acessíveis em grande variedade no mercado e no SUS, são o método contraceptivo mais aceito pelas mulheres, entretanto trazem diversos efeitos colaterais. O objetivo deste trabalho foi analisar como a pílula anticoncepcional pode alterar as principais vias metabólicas femininas. Trata-se de uma revisão bibliográfica nas bases de dados SciELO, BVS e PubMed, com foco nas correlações entre o uso da pílula anticoncepcional e as alterações metabólicas. Os anticoncepcionais orais atuam na inibição da biossíntese de androgênios e estimulação da SHBG, o que reduz o efeito anabólico proteico. Também promovem o acréscimo dos níveis de LDL-colesterol, colesterol total, PCR-us e dímero D, e alterações na sensibilidade da insulina, no metabolismo do zinco e na hemostasia. Apesar de existirem recomendações que preconizam o uso de outros métodos contraceptivos e estudos que demonstram a satisfação feminina ao trocar os anticoncepcionais orais pelos LARCs, a pílula ainda é a mais utilizada pelas mulheres.(AU)

Contraceptive pills are steroids that prevent unwanted pregnancy and regular menstrual disorders. Accessible in a great variety in market and SUS, they are the contraceptive method most accepted by women, however, they bring several side effects. The objective of this study was analyze how the contraceptive pill can alter the main female metabolic pathways. This is a literature review in the SciELO, BVS and PubMed databases, focusing on the correlations between the use of contraceptive pill and metabolic alterations. Oral contraceptives act to inhibit androgen biosynthesis and stimulate SHBG, which reduces the protein anabolic effect. They also bring about high levels of LDL cholesterol, total cholesterol, CRP, D-dimer, changes in insulin, absence of zinc metabolism and hemostasis. Although there are recommendations that recommend the use of other contraceptive methods and studies that demonstrate the satisfaction of women in exchanging oral contraceptives with LARCs, the pill is still the most used by women.(AU)

Experiencia en la colocación del DIUPP / Experience in the placement of the Diupp

Family planning is a key intervention to decrease the mortality rates and maternal morbidity, and neonatal mortality rates of children by mean of the preventiion of unwanted pregnancies, the same as pregnancies that happen very clsely to another previous one with little space between them. Several studies performed in different parts of the world have demonstrated adverse results related specially with the spaciament of the pregnancies. The risks are particularly higher with women wich get pregnant les after than a previous deliver, spontaneous abortion or induced abortion. The instrauterine device (ID) is a family planning higly efficacious with a prolongued action and reversible, that offers security to most postpartum women, including those who are still nursing. The primary aim of the present report was to determine the frequency in the placement of the DIUPP in our Obstetrical Department between 01/06/2017 and 30/06/2018, and in a second instance, to describe the method for placement of the DIUPP, to determine the curve of learning, to measure the rate of expulsion of the device, and to evaluate the conformity of the users of the method. Unplanned pregnancies have strongly increased, and for that circumstance, we believe that with new strategies, such as it is with the post-event anticonception, we can improve the reproducive health (AU)

Tasa de embarazo en mujeres usuarias de implantes subdérmicos, en un instituto prestador de salud del sur de Bogotá / Pregnancy Rates in Women Using Subdermal Contraceptive Implants at a Healthcare Institution in Southern Bogotá / Taxa de gravidez em mulheres usuárias de implantes subdérmicos, em um instituto prestador de saúde do sul de Bogotá, Colômbia

Resumen: Este artículo determina las tasas de embarazo en usuarias de implantes Jadelle e Implanon y el porcentaje de continuidad de este método durante su uso en pacientes de un instituto prestador de salud (IPS) del sur de la ciudad. A través de un estudio descriptivo se revisaron las bases de datos de 14.566 mujeres fértiles que asistieron a la consulta de planificación para portar el implante sub-dérmico entre 2014 y 2017. Gracias a esto, se encontró que la tasa de embarazo promedio en este periodo fue, para el Jadelle, de 2,81 por 1000, y para el Implanon, de 1,19 por 1000, lo que evidencia cifras mayores a las esperadas. Asimismo, se evidenció que la colocación del implante después de la fecundación es la principal causa del aumento de las tasas. El fallo de los implantes valorado por la presencia de embarazo es inferior al 1 %, pero para mantener esta cifra se debe realizar rutinariamente una detección precoz de embarazo.

Abstract: This article determines the pregnancy rates in Jadelle and Implanon users and the percentage of continuity of this method in patients of a healthcare institution (IPS) in the south of the city. Through a descriptive study, the databases of 14,566 fertile women who attended contraception appointments to get a subdermal implant between 2014 and 2017 were reviewed. As a result, it was found that the average pregnancy rate for this period was 2.81 per 1000 for Jadelle and 1.19 per 1000 for Implanon, figures higher than expected. It was also noted that implant placement after fertilization is the main cause of increase in these rates. Implant failure due to existing pregnancy is less than 1 %, but to maintain this figure, early pregnancy tests should be routinely performed.

Resumo: Este artigo determina as taxas de gravidez em usuárias de implantes Jadelle e Implanon e a porcentagem de continuidade desse método durante seu uso em pacientes de um instituto prestador de saúde (IPS) do sul de Bogotá, Colômbia. Por meio de um estudo descritivo, foram revisadas as bases de dados de 14.566 mulheres férteis que foram à consulta de planejamento para ter o implante subdérmico entre 2014 e 2017. A partir disso, foi verificado que a taxa de gravidez média no período foi, para o Jadelle, de 2,81 por 1.000 e, para o Implanon, de 1,19 por 1.000, o que evidencia cifras maiores às esperadas. Além disso, foi constatado que a colocação do implante depois da fecundação é a principal causa do aumento das taxas. A falha dos implantes avaliada pela presença de gravidez é inferior a 1%, mas, para manter essa cifra, deve-se realizar uma detecção precoce da gravidez.

The use of emergency hormonal contraception in South Africa: current and future perspectives

Emergency hormonal contraceptives play an important role in preventing unplanned pregnancies in South Africa. In this review,we discuss the levonorgestrel emergency contraceptive, the combined estrogen and progestin regimen (also known as the Yuzpe method) and the use of Ulipristal acetate. The levonorgestrel and the combined estrogen, progestin regimen are available in South Africa. The specific mechanisms of action of each of these emergency hormonal contraceptives will be discussed as well as their efficacy, the side effects associated with each of these preparations and the drug interactions. Levonorgestrel can be used as a single dose (1.5 mg) instead of two doses (0.75 mg) 12 hours apart. Levonorgestrel is very effective, with fewer adverse effects than the combined estrogen and progestogen administration. Levonorgestrel and the Yuzpe method have demonstrated good efficacy when utilised within 72 hours after unprotected intercourse or contraceptive failure. These emergency hormonal contraceptives should not be used as regular contraception. It is essential that all health professionals and educators inform women of reproductive age about the risks and common side effects of emergency hormonal contraceptives
