RESUMEN

PURPOSE: This study aimed to explore the relationship between oral contraceptive use and blood pressure values and in a national cohort of women adolescents and to investigate the level of coexistence of the high blood pressure levels, dyslipidemia or insulin resistance. METHODS: This is a retrospective cohort study that evaluated data form 14,299 adolescents aged 14 to 17 years. Crude and race-and age-adjusted analyses were performed using Poisson regression to estimate the prevalence ratios. Data clustering analysis was performed using machine learning approaches supported by an unsupervised neural network of self-organizing maps. RESULTS: We found that 14.5% (n = 2076) of the women adolescents use oral contraceptives. Moreover, an increased prevalence of high blood pressure, dyslipidemia, and insulin resistance (all P < 0.001) was observed among adolescents who use oral contraceptives as compared to those who do not. Our analysis also showed that 2.3% of adolescents using oral contraceptives had both high blood pressure levels and dyslipidemia, whereas 3.2% had high blood pressure levels combined with insulin resistance (all P < 0.001). The algorithmic investigative approach demonstrated that total cholesterol, LDLc, HDLc, insulin, and HOMA-IR were the most predicted variables to assist classificatory association in the context of oral contraceptive use among women adolescents with high blood pressure. CONCLUSIONS: These findings suggest that oral contraceptives were associated with an increased prevalence of high blood pressure, dyslipidemia, and insulin resistance among women adolescents. Although the indication of this therapy is adequate to avoid unintended pregnancies, their use must be based on rigorous individual evaluation and under constant control of the cardiometabolic risk factors.

RESUMEN

Coronavirus 19 disease (COVID-19) presents a highly variable clinical presentation and course, ranging from asymptomatic patients to rapidly progressive, fatal pneumonia. The known heterogeneous outcomes can affect both previously healthy patients and those with significant comorbidities, who develop clinical courses with possibly more multisystemic compromise. Likewise, the development of thrombotic phenomena during the acute course of the disease is associated with complications that worsen patient prognosis. We present a case report of a 45-year-old multiparous patient with a history of overweight and chronic use of oral hormonal contraception with low doses of levonorgestrel and estradiol as the only risk factors favoring the development of thrombotic events. During her outpatient COVID-19 clinical course, she developed massive pulmonary thromboembolism resulting in secondary obstructive shock, which required pharmacological thrombolysis. At discharge, hormonal contraception was considered contraindicated, and the patient was released from our institution with continued oral anticoagulant therapy. COVID-19 infection, contraceptive hormone therapy, and overweight are known risk factors for the development of thromboembolic events. The impact of their concomitance has not been studied to date. From our experience, we discuss the impact these risk factors have when present together and invite others to report similar cases.

RESUMEN

Resumen: OBJETIVO: Determinar la asociación entre los márgenes afectados con la persistencia-recurrencia de neoplasia intraepitelial cervical, persistencia del virus del papiloma humano y las reintervenciones. MATERIALES Y MÉTODOS: Estudio de casos y controles anidado en una cohorte retrospectiva del Complexo Hospitalario Universitario de Ourense (enero 2010-octubre 2017). Criterio de inclusión: mujeres con al menos una revisión postintervención. Criterios de exclusión: mujeres sin evidencia de displasia de alto grado en la pieza de conización y a las que no se dio seguimiento. Variables de estudio: edad, tabaquismo, preservativo, anticonceptivos orales, vacunación contra VPH, persistencia-recurrencia de NIC y de VPH y reintervención. Se realizaron pruebas paramétricas y no paramétricas entre las variables. RESULTADOS: La cohorte se integró con 248 mujeres, de éstas 81 (32.6%) tuvieron afectación de los márgenes quirúrgicos en la conización. La inmunosupresión, el tabaquismo y la anticoncepción oral fueron las asociaciones más frecuentes en los márgenes afectados. El uso de preservativo y la vacunación contra VPH fueron significativamente más frecuentes en los márgenes libres. Los márgenes afectados reportaron mayor persistencia de VPH (50 vs 23.9%; OR 3.17 (1.90-5.26), p < 0.001), enfermedad persistente-recurrente (47.2 vs 22.5%; OR 3.07 (1.84-5.12), p < 0.001) y reintervenciones (40.2 vs 15.4%; OR 3.679 (2.094-6.463), p < 0.028). El margen más afectado fue, en orden descendente, endocervical (55.6%), exocervical (25%) y ambos (19.4%). CONCLUSIONES: El margen afectado confiere un riesgo importante en la evolución de la infección por VPH y la recurrencia de la enfermedad.

Abstract: OBJECTIVE: To determine the association between affected margins with persistence-recurrence of cervical intraepithelial neoplasia, persistence of human papillomavirus and re-interventions. MATERIALS AND METHODS: Study of cases and controls nested in a retrospective cohort of the Complexo Hospitalario Universitario de Ourense (January 2010-October 2017). Inclusion criteria: women with at least one post-intervention check-up. Exclusion criteria: women without evidence of high-grade dysplasia in the conization piece and who were not followed up. Study variables: age, smoking, condom, oral contraceptives, HPV vaccination, persistence-recurrence of CIN and HPV, and re-operation. Parametric and non-parametric tests were performed among the variables. RESULTS: The cohort consisted of 248 women, 81 of whom (32.6%) had affected surgical margins on conization. Immunosuppression, smoking and oral contraception were the most frequent associations in affected margins. Condom use and HPV vaccination were significantly more frequent in free margins. Affected margins reported greater persistence of HPV (50 vs 23.9%; OR 3.17 (1.90-5.26), p < 0.001), persistent-recurrent disease (47.2 vs 22.5%; OR 3.07 (1.84-5.12), p < 0.001), and reinterventions (40.2 vs 15.4%; OR 3.679 (2.094-6.463), p < 0.028). The most affected margin was, in descending order, endocervical (55.6%), exocervical (25%) and both (19.4%). CONCLUSIONS: The affected margin confers a significant risk in the evolution of HPV infection and disease recurrence.

RESUMEN

PURPOSE: To determine the effects of oral contraceptive (OC) use on salivary concentrations of testosterone, estrogen, progesterone, and its effects on the changes in indirect markers of muscle damage following eccentric cycling in women. METHODS: 10 oral contraceptive users at follicular phase (OC-FOL), 10 non-oral contraceptives users at follicular phase (NOC-FOL), and 10 non-oral contraceptives users at ovulation phase (NOC-OV) participated. Subjects performed 30 min of eccentric cycling at 90% of their maximal concentric power output (PO). Maximal voluntary isometric contraction (MVC), creatine kinase activity (CK), muscle soreness (SOR), and pain pressure threshold of vastus lateralis (PPT-VL) was assessed before, immediately after, and 24-96 h after cycling. Salivary estrogen, progesterone and testosterone concentrations were measured before, 72 and 96 h after exercise. RESULTS: No difference in estrogen levels between users and non-users was observed. Testosterone was 45% lower in OC-FOL than NOC-FOL at 96 h post-exercise (P = 0.01). Progesterone was 30.8-fold higher in NOC-OV than OC-FOL and 9.7-fold higher than NOC-FOL at 96 h post-exercise. The NOC-FOL recovered all indirect markers of muscle damage by 72 h post-exercise (P > 0.05). NOC-OV recovered MVC strength and muscle soreness (SOR and PPT-VL) by 96 h post-exercise (P > 0.05). OC-FOL did not recover baseline values of MVC, SOR, CK, and PPT-VL by 96 h. CONCLUSION: These results suggest that recovery after exercise-induced muscle damage took longer in OC-FOL, followed by NOC-OV and by NOC-FOL, respectively. Furthermore, testosterone and progesterone levels may affect recovery of indirect markers of muscle damage in women.

RESUMEN

The purpose of the study was to evaluate whether the intake of hormonal oral contraceptive influences the viability of mesenchymal stem cell. Sixteen healthy female volunteers with regular menstrual cycles were invited to participate. Menstrual fluid was collected on the day of maximum flux, and collected cells were analyzed by a 'minimal standard' for MSC characterization: plastic adherence, trilineage (adipogenic, osteogenic, chondrogenic) in vitro differentiation and a minimalistic panel of markers assessed by flow cytometry (CD731, CD901, CD1051, CD34-, CD45-) using monoclonal antibodies. The participants were divided into two groups: Group 1 - no hormonal contraceptive use; Group 2 - hormonal oral contraceptive use. The median of the menstrual fluid volume was 5.0 and the median number of cells was 5.2 × 106. Median of cell viability was 89.3%. After culture, mesenchymal stem cells increased from 0.031% of the total cells to 96.9%. The cells formed clusters and reached confluence after 15-21 days of culture in the first passage. In the second passage, clusters and the confluence were observed after 3 days of culture. No difference was observed between the groups. Our data suggest that oral hormonal contraceptive intake maintains the viability of mesenchymal stem cells from menstrual fluid.

RESUMEN

Introducción: La necesidad insatisfecha de anticoncepción sigue siendo alta en el Perú y a nivel mundial. La asesoría adecuada del profesional de la salud ha demostrado maximizar el uso y cumplimiento de métodos anticonceptivos que se ajusten a las necesidades de cada mujer. Objetivos: Medir el impacto de la asesoría brindada por profesionales de salud ginecoobstetras en la elección de un método anticonceptivo hormonal de autoadministración -píldora diaria, parche transdérmico semanal y anillo vaginal mensual-, así como los factores determinantes de ello. Diseño: Estudio observacional, descriptivo y transversal. Lugar: Lima, Piura, Chiclayo y Trujillo, Perú. Institución: Proyecto Latinoamericano PIENSA: Programa de Investigación y Educación en Salud Anticonceptiva. Participantes: Quinientos ochenta y un mujeres de 18 a 40 años que acudieron a la consulta de 40 ginecoobstetras que brindaron asesoría sobre métodos anticonceptivos. Intervenciones: Se realizó una asesoría estandarizada con material didáctico que contenía información sobre efectividad, mecanismo de acción, modo de uso, beneficios y riesgos, así como idoneidad, respecto a las necesidades individuales. Principales medidas de resultados: Elección original y elección final del método anticonceptivo luego de la asesoría, y factores involucrados. Resultados: La elección inicial del método fue de 57% la píldora, 15% el anillo vaginal y 13% el parche transdérmico; luego de la asesoría fue: 38% la píldora, 33% el anillo vaginal, y 19% el parche transdérmico. Resultó estadísticamente significativa la preferencia entre las usuarias del anillo vaginal de 15% a 33% y la preferencia del parche transdérmico de 13 a 19%; p<0,005. La razón principal para la elección del método fue la facilidad de uso. Conclusiones: Las mujeres peruanas participantes del proyecto PIENSA eligieron inicialmente la píldora diaria, cuyo porcentaje disminuyó luego de la asesoría por un profesional de la salud. Asimismo, el número de mujeres que eligieron los métodos de parche transdérmico y anillo vaginal se incrementó significativamente.

Introduction: Unmet needs for contraception are high in Peru and worldwide. Proper advice from health professionals maximizes use and compliance of contraceptive methods meeting the needs of every woman. Objectives: To determine the impact and determinant factors of gynecologists advice for women choosing a self-administered hormonal contraceptive method, either daily pill, weekly transdermal patch or monthly vaginal ring. Design: Observational, descriptive and transversal study. Location: Lima, Piura, Chiclayo, and Trujillo, Peru. Institution: Latin Project PIENSA: Program for Research and Education on Contraceptive Health. Participants: Five hundred eighty-one women aged 18 to 40 attended by 40 gynecologists providing advice on contraception. Interventions: Standardized counseling with educational material including information on effectiveness, mechanism of action, user mode, benefits and risks as well as suitability in regards to individual needs was conducted. Main outcome measures: Original choice and final election of contraceptive method following counseling as well as factors involved. Results: Initial method choice was 57% for the pill, 15% for the vaginal ring, and 13% for transdermal patch. Following advice election was for pill 38%, vaginal ring 33%, and transdermal patch 19%. Statistically significant preference from 15% to 33% was found in vaginal ring users, and 13% to 19% for transdermal patch; p <0,005. The main reason for methods choice was ease of use. Conclusions: Peruvian women participating in PIENSA Project initially chose the daily contraceptive pill; but this election decreased following health professional counseling. The number of women who chose transdermal patch and vaginal ring increased significantly.

RESUMEN

BACKGROUND: An oral dose of 0.75 mg levonorgestrel (LNG) taken shortly after sex was marketed as a routine, nonemergency contraceptive method until the 1990s. Because a hormonal method used only at the time of intercourse may be desirable for women who have infrequent sex, we conducted a study to reevaluate the potential of pericoital LNG as a primary means of contraception. METHODS: We enrolled women aged 18-45 years in Brazil and the USA who expected to have sex 1-4 days per month for 6.5 months. Participants were instructed to take one tablet 0.75 mg LNG within 24 h before or after sex, with no more than one dose in any 24-h period. The primary efficacy measure was the Pearl Index among women aged 18-35 years. RESULTS: The study was stopped after 72 of the planned 300 participants were enrolled due to slow recruitment and related feasibility considerations. In the primary analysis, three pregnancies occurred during 13.4 woman-years of follow-up, resulting in a Pearl Index of 22.4 (95% confidence interval, 4.6-65.4). No serious adverse events were reported, and vaginal bleeding patterns were generally acceptable. CONCLUSIONS: Our estimated Pearl Index was noticeably higher than expected from previous research of LNG for pericoital contraception. Although the regimen was safe and generally acceptable, the study was challenged by slow enrollment and curtailed person-years of follow-up, resulting in poor precision for the estimated treatment effect. Future research may inform whether our results are symptomatic of the regimen, study design or characteristics of the populations from which we recruited. IMPLICATIONS: Our study failed to confirm prior data suggesting that 0.75 mg LNG for pericoital contraception could be more effective than typical use of barrier methods among women having infrequent sex. Characterizing populations most likely to adhere to, and benefit from, pericoital regimens is essential to future research on these methods.
