Immediate vs delayed postpartum insertion of long-acting reversible contraception methods: meta-analysis of randomized controlled trials.

OBJECTIVE: We aimed to conduct a meta-analysis of randomized trials comparing the immediate vs delayed provision of long-acting reversible contraceptives in postpartum subjects, focusing on short-interval pregnancies, utilization rates, and adverse events. DATA SOURCES: Cochrane Central, Embase, PubMed, and ClinicalTrials.gov were systematically searched from inception up to December 19, 2023, without filters or language limitation. STUDY ELIGIBILITY CRITERIA: We selected randomized controlled trials assessing the immediate insertion of long-acting reversible contraceptives in women during postpartum period in comparison with the delayed provision. STUDY APPRAISAL AND SYNTHESIS METHODS: We calculated relative risks with 95% confidence intervals to analyze the primary outcome of utilization rates and secondary endpoints, including initiation rates, pregnancy, any breastfeeding, exclusive breastfeeding, and serious adverse events. A random-effects model was employed in the R software. Moreover, we assessed the risk of bias of selected randomized controlled trials using version 2 of the Cochrane Risk of Bias Assessment Tool. RESULTS: We included 24 randomized trials comprising 2507 participants, of whom 1293 (51.6%) were randomized to the immediate insertion. Postpartum women in the immediate group had lower risk of pregnancy (relative risk 0.16; 95% confidence interval 0.04-0.71; P=.02) compared with delayed group, and higher rates of long-acting reversible contraceptives at 6 months of follow-up (relative risk 1.23; 95% confidence interval 1.09-1.37; P<.01). CONCLUSION: Inserting long-acting reversible contraceptives before hospital discharge was associated with a reduction in the risk of pregnancy, and increased rates of its utilization at 6 months of follow-up. This intervention may be an effective contraception strategy for postpartum women.

Transgenerational effects of the levonorgestrel-based birth control pill in zebrafish offspring.

The consumption of hormone-derived medicines, such as levonorgestrel (LNG), is increasing worldwide, and its discharge into the environment reaches non-target organisms. In our previous study, we exposed the parental generation of zebrafish to environmentally relevant concentrations of LNG during the developmental phase. Subsequently, they had grown in a tank with clean water until adulthood. Now, we allowed this parental generation to reproduce to obtain F1 progeny unexposed to LGN, in order to analyze the transgenerational effects of parental LNG exposure on the survival and hatching of unexposed F1 embryos and the stress and behavior of F1 larvae. Here, we found decreased survival rates with higher LNG concentrations, providing a transgenerational effect. This highlights the environmental impact of exposure to LNG, causing damage at the individual and population level and affecting the next generation at the beginning of development, impacting qualities in the survival of the species.

Knowledge, Use, and Perception of Brazilian Women about Contraceptive Methods: An Observational Study.

Background: In Brazil, where approximately 48.7 million women are of reproductive age, understanding contraceptive practices is essential for addressing public health challenges. This study evaluated into the knowledge, usage, and perceptions of contraceptive methods among Brazilian women, highlighting the influence of socioeconomic and demographic factors on their choices. Methods: We conducted a cross-sectional survey with a representative sample of 2000 Brazilian women aged 18-49 years. The questionnaire collected detailed information on their awareness, preferences, and utilization of various contraceptive methods, alongside demographic and socioeconomic data. Results: Oral contraceptives, condoms, injectables, and intrauterine devices (IUDs) were the most recognized methods. Younger women demonstrated greater awareness of modern methods. Socioeconomic disparities were evident, with lower-income women displaying limited knowledge about condoms and IUDs but a higher usage for injectable contraceptives. Oral contraceptives were the most used method, with higher use in the South, and lower in the Central-West and Northeast regions. Satisfaction with current contraceptive methods was high (87.5%), closely associated with personal responsibility in method choice. Although the majority self-financed their contraceptives (63.1%), a significant portion of lower-income women (27.7%) relied on public health care. Physicians' recommendations predominantly influenced contraceptive choice (53.9%), with younger women also guided by other influences. Conclusions: Persistent disparities in contraceptive awareness and access highlight the need for educational initiatives and policy interventions. Health care providers play a vital role in facilitating informed contraceptive choices, enhancing the chances of satisfaction with the method.

Combined oral contraceptive use and obesity in women with polycystic ovary syndrome. A meta-analysis of randomized clinical trials.

BACKGROUND: Polycystic ovary syndrome (PCOS) is a heterogenous endocrine condition and combined oral contraceptives (COCs) have been demonstrated to be the first-line treatment to women who do not intend to become pregnant. The combination of COCs and PCOS may or may not amplify the risks of cardiovascular events. OBJECTIVE: To investigate whether surrogates for obesity may be influenced by the use of COCs containing different formulations in women with PCOS. METHOD: From January 2024 a literature search was conducted in Google Scholar and Pubmed databases using PCOS, COC, and obesity terms. Hand search of randomized clinical trials in the references of obtained manuscripts was also performed. After the exclusion of reviews and articles that did not fulfill eligibility criteria, compared the results obtained before and after the use of COCs in 13 randomized clinical trials (RCTs). Random-effects model was used to estimate the standardized mean differences (SMD) and standard errors (SE). Risk of bias was examined using the Rob2 tool. RESULT: Thirteen heterogeneous RCTs reported no difference in waist circumference with the use of different COC formulations (p = 0.714). On the contrary, body fat mass increased with the use of pill (p = 0.013). Waist triglyceride index and lipid accumulation product tended to be higher after the use of COCs (p = 0.073 and p = 0.064, respectively). CONCLUSION: Combined oral contraceptives with different formulations might increase fat mass accumulation in women with PCOS. Lipids may also be increased in PCOS users. Because some concerns about the quality and heterogeneity identified in various RCTs, caution should be taken before a definitive conclusion regarding the use of COCs and obesity.

Differential Effect of 2 Hormonal Contraceptives on the Relative Telomere Length of Youth With Type 1 Diabetes.

Context: Adolescents and young women (AYA) with type 1 diabetes (T1D) may require hormonal contraception for an extended period. However, it is unclear what effect hormonal contraception has on telomere length, a marker of the risk for complications. Objective: To investigate the relative telomere length (RTL) in AYA with T1D (AYA-T1D) and healthy young women (AYA-C) after 18 months of combined oral contraception use (COC) with ethinyl estradiol/desogestrel, or a subdermal etonogestrel implant (IM). Methods: A nonrandomized prospective study was performed in which 39 AYA-T1D and 40 AYA-C chose the COC or the IM. RTL was measured by monochrome multiplex-quantitative PCR in DNA from peripheral blood mononuclear cells (PBMC). The impact of contraceptives and clinical variables on RTL was assessed using lineal regression analysis. Results: Longer RTL compared to baseline was observed in AYA-T1D (P < .05) and AYA-C (P  < .01) after using the IM. However, the total of AYA and the AYA-C group treated with COC decreased RTL after 18 months of treatment compared to baseline (P < .05). The type of contraceptive used was determinant for the changes in RTL compared to baseline in all subjects and controls (P ≤ .006). For AYA-T1D, HbA1c levels were not associated with RTL, but the high-sensitivity C-reactive protein was negatively related with the changes in RTL at 18 months compared to baseline (standardized R2 : 0.230, P  = .003). Conclusion: IM was associated with longer RTL in AYA-T1D and AYA-C. In contrast, a shortening of telomere length in PBMC was observed after using COC.

El papel del estetrol en la anticoncepción: una revisión integral / The role of estetrol in contraception: a comprehensive review

Esta revisión narrativa explora el papel potencial del estetrol (E4), un esteroide estrogénico natural, en la anticoncepción, analizando sus propiedades farmacológicas, su efectividad y su seguridad. Se revisaron estudios preclínicos, ensayos clínicos y evaluaciones de seguridad del E4 como anticonceptivo oral combinado (AOC). Se investigó el impacto en parámetros endocrinos, metabólicos y hemostáticos, así como su tolerabilidad. En los resultados, el E4 tiene menor afinidad por el receptor de estrógeno-α de membrana, pero mantiene la actividad agonista en los receptores nucleares. E4/DRSP (drospirenona) demostró ser un AOC eficaz, con ciclos de sangrado regulares y predecibles en la mayoría de las mujeres. La tolerabilidad fue favorable, con eventos adversos leves o moderados y bajas tasas de interrupción. El sangrado fue el evento adverso más común, y se reportaron casos raros de migrañas con aura, trombosis venosa profunda, hiperpotasemia y depresión. E4/DRSP tuvo mínimo impacto en los parámetros lipídicos, hepáticos, de globulina fijadora de hormonas sexuales y de metabolismo de hidratos de carbono, y efecto neutral o mínimo en los parámetros hemostáticos. Se concluye que E4/DRSP parece ser una opción anticonceptiva eficaz y segura, con reducido riesgo trombótico y mínimo impacto en los parámetros endocrinos y metabólicos. Se requiere más investigación para confirmar su seguridad y eficacia a largo plazo.

This narrative review explores the potential role of estetrol (E4), a natural estrogenic steroid, in contraception, analyzing its pharmacological properties, effectiveness, and safety. Preclinical studies, clinical trials, and safety assessments of E4/DRSP (drospirenone) as a combined oral contraceptive (COC) were reviewed. The impact on endocrine, metabolic, and hemostatic parameters, as well as tolerability, was investigated. In results, E4 exhibits lower affinity for estrogen transmembrane receptor-α but maintains agonistic activity on nuclear receptors. E4/DRSP proved to be an effective COC with regular and predictable bleeding cycles in most women. Tolerability was favorable with mild or moderate adverse events and low discontinuation rates. Bleeding was the most common adverse event, and rare cases of aura migraines, deep vein thrombosis, hyperkalemia, and depression were reported. E4/DRSP had minimal impact on lipid, hepatic, sex hormone-binding globulin, and carbohydrate metabolism parameters, with a neutral or minimal effect on hemostatic parameters. The conclusion is that E4/DRSP seems to be an effective and safe contraceptive option, with reduced thrombotic risk and minimal impact on endocrine and metabolic parameters. Further research is needed to confirm long-term safety and efficacy.

Daño hepático inducido por uso de anticonceptivos orales en una paciente con ictericia prolongada y transaminasas elevadas: reporte de caso / Drug-induced liver injury secondary to the use of oral contraceptives in a patient with prolonged jaundice and elevated transaminases: Case report

La hepatotoxicidad inducida por medicamentos es un diagnóstico de descarte. Típicamente, se presenta en pacientes que desarrollan cambios clínicos y bioquímicos compatibles con hepatitis, pero relacionados con el inicio reciente de agentes farmacológicos, y que se resuelven tras el retiro de la noxa. Su desarrollo se ha descrito con el uso de algunos antibióticos, antituberculosos, estatinas, herbolarios y antiinflamatorios no esteroideos; sin embargo, hay pocos reportes de casos con el uso de anticonceptivos orales, en los cuales el surgimiento de mecanismos idiosincráticos puede llevar a la presentación de características clínicas como ictericia y anormalidades en los exámenes de laboratorio, como la elevación de las transaminasas. Esto requiere de estudios extensos para descartar otras patologías que pueden presentarse de esta forma, lo que representa un reto clínico. En este artículo se muestra el reporte de un caso de una paciente con antecedente de uso crónico de anticonceptivos implantables y que, tras el ajuste de la terapia con el inicio de anticonceptivos orales, desarrolla un episodio de elevación marcada de transaminasas e ictericia.

Drug-induced liver injury is a rule-out diagnosis. Typically, it occurs in patients who develop clinical and biochemical changes compatible with hepatitis, but related to a history of recent onset of pharmacological agents, and resolves after withdrawal of the noxious substances. Its development has been described with the use of some antibiotics, antituberculosis agents, statins, herbal and nonsteroidal anti inflammatory drugs; however, there are few reports of cases with the use of oral contraceptives, in which the appearance of idiosyncratic mechanisms can lead to the presentation of clinical features such as jaundice and laboratory tests abnormalities, like transaminase elevation, requiring extensive studies to rule out other pathologies that may have this clinical presentation, wich represents a clinical challenge. We present a case report of a patient who had chronic use of implantable contraceptives and who, after adjustment of therapy with the start of oral contraceptives, developed an episode of marked elevation of transaminases and jaundice.

Performance of a handheld point of care ultrasonography to assess IUD position compared to conventional transvaginal ultrasonography.

OBJECTIVE: To compare the performance of the abdominal handheld point-of-care ultrasonography (POCUS) Butterfly-iQ to gold standard transvaginal ultrasonography (US) in identifying the position of intrauterine devices (IUDs) in the hands of a medical doctor specialised in ultrasonography. METHODS: In this diagnostic accuracy study, a single operator conducted abdominal POCUS followed by conventional transvaginal US. Seventy patients utilising copper or hormonal IUDs were assessed between June 2021 and October 2022. IUDs were categorised as entirely within the uterine cavity or malpositioned. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were calculated for detecting malpositioned IUDs, with conventional US results serving as the reference standard. Concordance rate and Kappa coefficient were computed to assess the agreement between the two ultrasound modalities. RESULTS: Among the 70 patients, 46 (65.7%) used copper IUDs, and 24 (34.3%) used hormonal IUDs. Conventional transvaginal US showed IUDs entirely within the uterine cavity in 56 (80%) patients and 14 (20%) IUDs were malpositioned. Of the 14 malpositioned IUDs seen by conventional US, POCUS identified 13 demonstrating a sensitivity of 92.9% (66.1-99.8). Of the 56 IUDs entirely within the uterine cavity shown by conventional US, only two cases were considered malpositioned by POCUS demonstrating a specificity of 96.4% (87.7-99.6). The concordance rate was 95.7%, and the Kappa value was 0.87 in differentiating between IUDs entirely within the uterine cavity and those that were malpositioned. CONCLUSION: Abdominal POCUS using Butterfly-iQ, when administered by an imaging specialist, exhibited excellent performance in confirming IUDs entirely within the uterine cavity.

Through a smartphone-based handheld point-of-care ultrasonography it was possible to correctly evaluate the position of intrauterine devices (IUDs) in a sample of 70 patients (46 using copper and 24 using hormonal IUDs).

Long-acting reversible contraception use and unmet desire among patients after the Zika Contraception Access Network Program in Puerto Rico.

OBJECTIVES: To describe unmet desire for long-acting reversible contraception (LARC) after the Zika Contraception Access Network (Z-CAN) in Puerto Rico during the 2016-2017 Zika outbreak. STUDY DESIGN: Z-CAN patients completed surveys about contraception experiences over a 3-year period. RESULTS: Of 1809 respondents, 3% never used LARC but reported wanting it since their initial visit. As reasons for not getting LARC, nearly 50% indicated a provider-related reason and 25% reported cost. CONCLUSIONS: Few Z-CAN patients who never used LARC had unmet desire. Provider training in contraception guidelines and strategies to address costs can expand access to the full range of reversible contraception. IMPLICATIONS: Three years after a short-term program provided reversible contraception in Puerto Rico, few respondents had never used but wanted a long-acting reversible contraception method. Nearly half reported provider-related reasons for not receiving long-acting reversible contraception, and 25% reported cost. Provider awareness of contraceptive guidance and method availability can support client-centered care.

Doble protección anticonceptiva en estudiantes de obstetricia: Un estudio de factores asociados / Contraceptive dual protection in midwifery students: A study of associated factors

Objetivo: Determinar los factores que se asocian con el uso de la doble protección anticonceptiva en estudiantes de obstetricia de una universidad pública de Lima, Perú. Métodos: Estudio analítico transversal, realizado en 217 estudiantes de obstetricia de la Universidad Nacional Mayor de San Marcos. Se aplicó la prueba chi cuadrado, además de la razón de prevalencia cruda y ajustada. Resultados: La prevalencia del uso de la doble protección anticonceptiva fue 41,5 %. En el análisis bivariado los factores asociados incluyeron la edad de 25 a 29 años (razón de prevalencia cruda: 1,57), procedencia de Lima (razón de prevalencia cruda: 2,07), embarazo previo (razón de prevalencia cruda: 1,91), aborto previo (razón de prevalencia cruda: 1,92), antecedente de infecciones de transmisión sexual en la pareja (razón de prevalencia cruda: 1,81), conocimiento sobre la doble protección (razón de prevalencia cruda: 3,16) y orientación en planificación familiar (razón de prevalencia cruda: 1,76). En el análisis multivariado, el conocimiento sobre la protección anticonceptiva mantuvo la asociación significativa (razón de prevalencia ajustada: 2,44). Conclusión: El conocimiento sobre la protección anticonceptiva es el único factor reproductivo que se asoció con una mayor probabilidad de uso de este método(AU)

Objective: To determine which factors are associated with the use of dual protection in obstetrics students from a public university in Lima, Peru. Methods: Analytical cross-sectional study, done in 217 obstetrics students from the Universidad Nacional Mayor de San Marcos. The chi-squared test was applied, in addition to the raw and adjusted prevalence ratio (PR) Results: The prevalence of the use of dual protection was 41.5%. In the bivariate analysis, the factors associated with it included: age from 25 to 29 years old (raw prevalence ratio: 1.57), Lima as a place of origin (raw prevalence ratio: 2.07), previous pregnancy (raw prevalence ratio: 1.91), previous abortion (raw prevalence ratio: 1.92), antecedent of STI in the couple (raw prevalence ratio: 1.81), knowledge about dual protection (raw prevalence ratio: 3,16), and orientation in family planning (raw prevalence ratio: 1.76). In the multivariate analysis, knowledge about contraceptive protection maintained its significant association (adjusted prevalence ratio: 2.44). Conclusions: Knowledge about contraceptive protection is the only reproductive factor that was associated with a higher probability of using this method(AU)

An exploratory study of the factors associated with use of contraceptive methods in young Chilean women aged 17-29 years.

OBJECTIVE: To explore factors related to the use of contraceptive methods in young Chilean women with higher education. METHODS: Using the 9th Chilean National Youth Survey, multinomial models were conducted to predict contraceptive methods used during the last intercourse among sexually initiated female college students aged 17-29 years who had already completed high school (n = 1828). RESULTS: The results indicate that using contraceptive methods at onset sexual activity was positively associated with the use of all contraceptive methods (relative risk ratio [RRR]immediate = 3.97, RRRdaily = 2.95, RRRlong-term = 1.82, P < 0.05). Having a previous unintended pregnancy increased the odds of using long-term contraceptive methods (RRR = 2.13, P < 0.05). Increased age of sexual initiation was associated with increased odds of using immediate contraception methods (RRRadolescence = 2.57, RRRyoung adulthood = 3.75, P < 0.05). Substance use was not associated with contraception methods used. Medium socioeconomic status, compared with high, decreased the odds of using immediate and daily contraceptive methods (RRR = 0.26, P < 0.05 for both). Low socioeconomic status was associated with decreased odds of using daily contraception (RRR = 0.39, P < 0.05). Finally, incomplete (RRR = 2.21, P < 0.05) or complete (RRR = 2.38, P < 0.05) professional education increased the odds of immediate contraceptive methods. CONCLUSIONS: To generate family planning policies aimed at university students, individual factors related to sexual behavior should be addressed in accordance with the local reality and with a gender focus.

Uptake, discontinuation, and continuation rate of long-acting contraceptive methods when offered at no cost in Campinas, Brazil.

OBJECTIVES: This study aimed to compare the uptake, reasons for discontinuation, continuation, and satisfaction of long-acting contraceptive methods (LARC) when offered at no cost in Campinas, Brazil. STUDY DESIGN: This was a prospective cohort study conducted at University of Campinas, Campinas, São Paulo, Brazil, including women aged 18 to 48 years, who adopted one of three methods. Participants underwent telephone follow-up every 3 months for up to 24 months after insertion. Satisfaction was assessed at the end of 2 years of use through the Likert scale. RESULTS: We invited 1222 women, and among the 971 women who volunteered to participate in follow-up, 414 (42.6%) chose the levonorgestrel 52-mg intrauterine device (IUD), 358 (36.9%) chose the etonogestrel (ENG) implant, and 199 (20.5%) chose the TCu380A IUD. Discontinuation due to bothersome bleeding was higher among users of the ENG implant (10/358; 2.4%) and the TCu380A IUD (32/199; 8.9%), and expulsion was higher for the TCu380A IUD (30/199; 15.1%). Women continued at 24 months were 340/414 (82.1%), 270/358 (75.4%), and 119/199 (59.8%) among users of the levonorgestrel 52-mg IUD, ENG implant, and TCu380A IUD, respectively. The users of the levonorgestrel 52-mg IUD (301/339, 88.8%), the ENG-implant (222/270, 82.2%), and the TCu380A IUD (105/119, 88.2%) were satisfied or very satisfied by 24 months of follow-up. CONCLUSIONS: The three LARC methods had great uptake, high continuation, and discontinuation due to bothersome bleeding was higher among users of the ENG implant and the TCu380A IUD, and expulsion was higher for the TCu380A IUD compared to the 52-mg levonorgestrel IUD. Most of the participants reported being very satisfied. IMPLICATIONS: When the LARC methods were offered at no cost in a Brazilian public clinic the uptake, satisfaction and continuation were high by 24 months after device placement, and high level of satisfaction was reported by most of the participants.

Factors associated with the discontinuation of hormonal contraceptives in women of Lima, Peru.

INTRODUCTION: Family planning is a right and a tool that offers the possibility of choosing how many children to have. Its importance lies in the possibility of avoiding an unwanted pregnancy and its consequences. Our objective was to determine the factors associated with discontinuing hormonal contraceptives in women of childbearing age who attended the La Libertad Health Center in January 2023. METHODS: The study was observational, analytical, and cross-sectional. A total of 100 women of childbearing age who were users of hormonal contraceptives were included. Descriptive statistics were performed, frequency measurements and measures of central tendency were calculated, bivariate statistics were performed and the prevalence ratio (PR) was calculated, and a robust Poisson regression model was performed to assess the associated independent factors. All calculations were made with a confidence level of 95%. RESULTS: The educational level (PR=1.74; 95% CI: 1.22-2.48, p=0.006), the distance to the health center (PR=7.32; 95% CI: 1.1-48.5, p=0.001), having presented adverse events (PR=26.38; 95% CI: 3.8-183, p=0.001), and that the health staff had not identified the need for contraception (PR=3.12; 95% CI: 0.87-11.10, p=0.01) were associated with stopping a hormonal contraceptive. After introducing the variables to the regression model, the only independently associated factor was having presented an adverse event with the use of hormonal contraceptives (adjusted prevalence ratio, APR=3.33; 95% CI: 2.1-5.2, p<0.001). CONCLUSIONS: In this population, the factors associated with the discontinuation of hormonal contraceptives were education level, distance to the health center, having presented some adverse event with its use, and that health staff had not identified the need for contraception. The only independently associated factor was having presented an adverse event.

Changes in contraceptive use during the second COVID-19 lockdown in Brazil: A web-based survey.

OBJECTIVE: We assessed contraceptive use changes during the second lockdown due to COVID-19 in Brazil and their associated factors. STUDY DESIGN: This was a longitudinal web-based study in which 725 non-pregnant Brazilian women aged 18 to 49 completed an online structured survey about their contraceptive practices in two rounds in 2021. Multivariate multinomial logistic regression was used to analyze factors associated with contraceptive use changes during COVID-19. RESULTS: Sixty percent reported they changed their contraceptive use during COVID-19, especially starting to use a method or switching to a more effective one (32%). In adjusted analysis, women who were ambivalent about a future pregnancy were more likely to switch to a more effective method (adjusted odds ratio [aOR] 2.33, 95% CI 1.42-3.83) and to stop using contraceptive (aOR 3.64, 95% CI 1.91-6.91). Women with a partner were less likely to switch to a more effective method (aOR 0.61, 95% CI 0.39-0.93) and to stop using contraceptive (aOR 0.53, 95% CI 0.31-0.93), but more likely to switch to a less effective method (aOR 2.25, 95% CI 1.16-4.34). Age was also associated with contraceptive use changes. CONCLUSIONS: Contraceptive use among Brazilian women during COVID-19 depended on their age and partnership status. During the period of the highest peak in the number of cases and deaths in the country, ambivalence towards a future pregnancy increased changes in contraceptive use. IMPLICATIONS: Contraceptive changes were observed during a two-wave web-survey in Brazil depending on women's age and partnership status. Ambivalence towards a future pregnancy increased changes in contraceptive use and should be considered in future studies regarding sexual and reproductive health and COVID-19 as well as in family planning program implementation.

Garlic Extract Reverses Ischemic Heart Disease in Female Rats Exposed to Combined Oral Contraceptive Pills

Abstract Background Garlic is an herbal medicinal plant with several pharmacological properties used for the management of various ailments. However, its potential in the reversal of ischemic heart disease induced by combined oral contraceptive pills is not well reported. Objective This study investigated the cardioprotective potential of aqueous garlic extract against cardiotoxicity induced by oral contraceptive pills. Methods Forty-six rats were used for this study. Six were used to determine the lethal dose (LD50), and 40 rats were divided randomly into 5 groups of 8 rats each. Group A received feed and distilled water. Group B received 0.6 mg/kg of oral contraceptive pills. Group C received 500 mg/kg of garlic extract. Group D received 0.6 mg/kg of oral contraceptive pills + 500 mg/kg garlic extract. Group E received 0.6 mg/kg of oral contraceptive pills + 700 mg/kg garlic extract. The animals were sacrificed, and blood and tissue samples were collected for biochemical and histological analysis. Statistical analysis was done using SPSS, and p values < 0.05 were considered significant. Results The acute toxicity dose of combined oral contraceptive pills was 1.5 mg/kg for albino rats. Combined oral contraceptive pills induced ischemic necrosis as revealed by the photomicrographs, in addition to elevation of serum cardiac troponin-1, lactate dehydrogenase, creatine kinase, and malondialdehyde levels. Treatment with garlic extract demonstrated significant reduction in cardiac troponin-1 (p = 0.000), lactate dehydrogenase (p = 0.002), creatine kinase (p = 0.001), and malondialdehyde (p = 0.001) levels, as well as restoration of the cardiac cytoarchitecture changes caused by the combined oral contraceptive pills. Conclusion This study has demonstrated that aqueous garlic juice can reverse ischemic heart disease, lessen cytoarchitectural alterations of the heart caused by combined oral contraceptive pills, and thus ameliorate cardiac dysfunction.

Acesso aos contraceptivos e direito à saúde em Angola: experiências de mulher e de farmacêutica / Access to contraceptives and the right to health in Angola: experiences of a woman and pharmacist

RESUMO Este relato apresenta uma proposta do que a escritora Conceição Evaristo chama de 'escrevivência' - escrita da mulher negra, que se mescla com vivência, relato de memórias e memórias de seu povo, visando incomodar consciências e ecoar nossas histórias. O 'escrever, viver e se ver' da autora é reconhecido como 'escrita da alma', lugar onde cada mulher escreve considerando o mundo que vive, de uma forma integrada. Visa fazer uma breve reflexão sobre o acesso aos medicamentos, tomando o acesso aos métodos contraceptivos em Angola como recorte, tendo em conta a vivência da autora. É um estudo qualitativo e a coleta de dados foi feita por meio de pesquisa documental, estudo de campo e entrevistas. Para o tratamento de dados foi adotada a análise de conteúdo. Identificou-se que o acesso aos métodos contraceptivos em território angolano é incipiente, resultado de políticas públicas e boa governança pouco efetivas, bem como a interferência externa pouco resolutiva. Estes, são reforçados pela herança colonial, que propicia abordagens em desacordo com as necessidades locais. É fundamental que os direitos sexuais e reprodutivos sejam encarados como questão política, de saúde pública e inerente à dignidade humana, para além da perspectiva eugenista de controle de natalidade.

ABSTRACT This report consists of what Conceição Evaristo calls 'writing and living' - the writing of black women, which mixes with experience, their memories, and the memories of their people, aiming to disturb consciences and echo our stories. The author's 'writing, living and self-seeing' is recognized as the 'writing of the soul', from where each woman writes considering the world she lives in. It aims to briefly reflect on access to medicines, focusing on the access to contraceptive methods in Angola, based on the author's experience. It is a qualitative study, and data were collected through documentary research, field study, and interviews. Content analysis was adopted for data processing. Access to contraceptive methods in Angolan territory is incipient, a result of ineffective public policies and good governance, as well as ineffective external interference. These are reinforced by colonial heritage, which provides approaches in disagreement with local needs. Sexual and reproductive rights must be seen as a political and public health issue inherent to human dignity, beyond the eugenic perspective of birth control.

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.

Aceptación y factores asociados con la anticoncepción moderna posaborto en mujeres atendidas en un hospital público / Acceptance and factors associated with modern post-abortion contraception in women treated in a public hospital

Resumen OBJETIVO: Determinar la frecuencia de aceptación y los factores asociados con la anticoncepción moderna posaborto en pacientes atendidas en un hospital público de Perú. MATERIALES Y MÉTODOS: Estudio observacional y transversal efectuado en pacientes en el posaborto inmediato atendidas de junio a diciembre de 2022 en el servicio de Urgencias del Hospital San Juan de Lurigancho, Lima, Perú, seleccionadas por conveniencia. Se utilizó un cuestionario validado. Se aplicó la prueba χ2 de Pearson con un nivel de significación del 5%. RESULTADOS: Se estudiaron 166 pacientes en el posaborto inmediato de las que el 94% (n = 156) aceptó algún método anticonceptivo moderno; el más frecuente fue el inyectable mensual (44.0%) y el menos aceptado el dispositivo intrauterino (0.6%). Los factores personales asociados con la aceptación del método anticonceptivo moderno fueron: edad (p < 0.01), no tener pareja (p < 0.001) y ésta estuviera de acuerdo con el anticonceptivo elegido (p < 0.001). Los factores institucionales asociados fueron: tiempo de la consejería en planificación familiar (p = 0.047), privacidad-confidencialidad de la consejería (p < 0.001) y satisfacción con la atención ofrecida durante la orientación (p = 0.026). CONCLUSIONES: La edad, carecer de pareja y estar de acuerdo con ésta acerca de la elección del método anticonceptivo posaborto junto con los factores institucionales (tiempo de consejería en planificación familiar, importancia de la privacidad-confidencialidad y percepción de la atención en consejería en planificación familiar) se asociaron, significativamente, con la aceptación de algún método anticonceptivo moderno posaborto.

Abstract OBJECTIVE: To determine the frequency of acceptance and factors associated with modern postabortion contraception in patients attended at a public hospital in Peru. MATERIALS AND METHODS: Observational and cross-sectional study conducted in immediate postabortion patients attended from June to December 2022 at the Emergency Department of the Hospital San Juan de Lurigancho, Lima, Peru, selected by convenience. A validated questionnaire was used. Pearson's test c2 was used with a significance level of 5%. RESULTS: We studied 166 patients in the immediate postabortion period, of whom 94% (n = 156) accepted some modern contraceptive method; the most common was the monthly injectable (44.0%) and the least accepted was the intrauterine device (0.6%). Personal factors associated with modern contraceptive method acceptance were age (p < 0.01), no partner (p < 0.001), and partner's agreement with the chosen contraceptive method (p < 0.001). Associated institutional factors were agreeing with the time of family planning counseling (p = 0.047), considering the importance of privacy-confidentiality of counseling (p < 0.001), and agreeing with the care offered during counseling (p = 0.026). CONCLUSIONS: Age, lack of a partner, and agreeing with the partner about the choice of postabortion contraceptive method along with institutional factors (time of family planning counseling, importance of privacy-confidentiality, and perception of care in family planning counseling) were significantly associated with acceptance of some modern postabortion contraceptive method.

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.

Contraindicated use of modern contraceptives among mothers from a Pelotas Birth Cohort

ABSTRACT OBJECTIVE To describe the prevalence of contraindicated use of combined hormonal contraceptives, progesterone-only contraceptives, and intrauterine devices in mothers participating in the 2015 Pelotas Birth Cohort according to the WHO medical eligibility criteria. METHODS The biological mothers of children belonging to the 2015 Pelotas birth cohort who attended the 48-month follow-up were studied. The 48-month follow-up data were collected from January 1, 2019, to December 31, 2019. Contraindicated use of modern contraceptives was considered to occur when these women presented at least one of the contraindications for the use of modern contraceptives and were using these methods. The prevalence of contraindicated use was calculated according to each independent variable and their respective 95% confidence intervals (95%CI). RESULTS The analyzed sample consisted of 3,053 women who used any modern contraceptive method. The prevalence of contraindicated use of modern contraceptives totaled 25.9% (95%CI: 24.4-27.5). Combined hormonal contraceptives showed the highest prevalence of contraindicated use (52.1%; 95%CI: 49.3-54.8). The prevalence of contraindicated use of modern contraceptives methods was greater in women with family income between one and three minimum wages, a 25-30 kg/m2 body mass index, indication by a gynecologist for the used method, and purchasing the contraceptive method at a pharmacy. The higher the women's education, the lower the prevalence of inappropriate use of modern contraceptives. CONCLUSION In total, one in four women used modern contraceptives despite showing at least one contraindication. Policies regarding women's reproductive health should be strengthened.
