Should intravitreal dexamethasone implant in refractory diabetic macular edema be used as an adjuvant therapy or switch therapy?

PURPOSE: To compare the outcomes of intravitreal dexamethasone implant used as either an adjuvant or a switching therapy for diabetic macular edema in patients with poor anatomic response after three consecutive monthly injections of ranibizumab. METHODS: This retrospective study included patients with diabetic macular edema who received three consecutive doses of ranibizumab as initial therapy and demonstrated poor response. A single dose of intravitreal de xamethasone implant was administered to these patients. The patients were divided into two groups according to the treatment modalities: the adjuvant therapy group, consisting of patients who continued treatment with ranibizumab injection after receiving intravitreal dexamethasone implant, and the switch therapy group, consisting of patients who were switched from ranibizumab treatment to intravitreal dexamethasone implant as needed. The main outcome measurements were best corrected visual acuity and central retinal thickness at baseline and at 3, 6, 9, and 12 months of follow-up. RESULTS: In this study that included 64 eyes of 64 patients, the best corrected visual acuity and central retinal thickness values did not significantly differ between the groups at baseline and at 6 months of follow-up (p>0.05). However, at 12 months, the best corrected visual acuity values in the adjuvant and switch therapy groups were 0.46 and 0.35 LogMAR, respectively (p=0.012), and the central retinal thickness values were 344.8 and 270.9, respectively (p=0.007). CONCLUSIONS: In a real-world setting, it seems more reasonable to use intravitreal dexamethasone implant as a switch therapy rather than an adjuvant therapy for diabetic macula edema refractory to ranibizumab despite three consecutive monthly injections of ranibizumab. Patients switched to intravitreal dexamethasone implant were found to have better anatomic and visual outcomes at 12 months than those who continued ranibizumab therapy despite their less-than-optimal responses.

Gene expression associated with unfavorable vaginal bleeding in women using the etonogestrel subdermal contraceptive implant: a prospective study.

To evaluate gene expression associated with unfavorable vaginal bleeding in users of the Etonogestrel (ENG) contraceptive implant. Prospective study involving 100 women who intended to use the ENG implant. Exclusion criteria included abnormal uterine bleeding, inability to attend a 1-year follow-up, and implant removal for reasons unrelated to vaginal bleeding or loss of follow-up. We obtained endometrial biopsies before implant placement and assessed the expression of 20 selected genes. Users maintained a uterine bleeding diary for 12 months post-implant placement. For statistical analysis, we categorized women into those with or without favorable vaginal bleeding at 3 and 12 months. Women with lower CXCL1 expression had a 6.8-fold increased risk of unfavorable vaginal bleeding at 3 months (OR 6.8, 95% CI 2.21-20.79, p < 0.001), while those with higher BCL6 and BMP6 expression had 6- and 5.1-fold increased risks, respectively. By the 12-month follow-up, women with lower CXCL1 expression had a 5.37-fold increased risk of unfavorable vaginal bleeding (OR 5.37, 95% CI 1.63-17.73, p = 0.006). Women with CXCL1 expression < 0.0675, BCL6 > 0.65, and BMP6 > 3.4 had a higher likelihood of experiencing unfavorable vaginal bleeding at 3 months, and CXCL1 < 0.158 at 12 months. Users of ENG contraceptive implants with elevated BCL6 and BMP6 expression exhibited a higher risk of breakthrough bleeding at the 3-month follow-up. Conversely, reduced CXCL1 expression was associated with an elevated risk of bleeding at both the 3 and 12-month follow-ups.

Short-term effect of intravitreal dexamethasone implant in refractory diabetic macular edema.

PURPOSE: To evaluate the short-term effects (hours-days) of intravitreal dexamethasone implant (IDI) in eyes with diabetic macular edema (DME) refractory to anti-vascular endothelial growth factor (VEGF) injections. METHODS: This was a prospective, single-arm, interventional clinical series. Eyes with DME and 3-9 injections of ranibizumab without a good response were included. Patients underwent a single IDI. Best-corrected visual acuity (BCVA) measurement, complete ophthalmic evaluation, and spectral-domain optical coherence tomography (SD-OCT) were performed at baseline, 2 h, 3 h, 24 h, 7 days, and 1 month. The main outcomes were change in central retinal thickness (CRT) on SD-OCT and BCVA. RESULTS: Fifteen eyes of 15 patients were included. Mean CRT decreased after treatment from 515.87 µm ± 220.00 µm at baseline to 489.60 µm ± 176.53 µm after 2 h (p = 0.126), and 450.13 µm ± 163.43 at 24 h (p = 0.006). Change in BCVA was from 0.85 ± 0.44 logMAR baseline to 0.58 ± 0.37 log MAR at 1 month (p = 0.003). CONCLUSIONS: Eyes treated with IDI showed significant decrease in CRT detectable 1 day after injection. In some patients, the effect could be observed 3 h post-implantation. TRIAL REGISTRATION: Clinicaltrials.gov NCT05736081 . Registered 20 February 2023, Retrospectively registered.

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.

Site necrosis at the insertion place of the single-rod subdermal contraceptive implant: report of five cases.

OBJECTIVE: Implant-site necrosis is a rare complication. We present a case-series of a necrosis as an adverse effect after the etonogestrel (ENG)-subdermal contraceptive implant placement. MATERIAL AND METHODS: Five women with site necrosis after the ENG-implant placement and their clinical manifestations and treatments. RESULTS: Local pain was the main symptom, appearing within 35 days of placement. Outpatient multidisciplinary treatment was undertaken. Local debridement and implant removal was performed in four out of the five women. Time to complete healing varied from 45 days to 12 months. CONCLUSION: Early diagnosis and multidisciplinary treatment are essential to avoid severe aesthetic or functional damages and major life-threatening complications.

We presented five cases with necrosis at the ENG-implant site of placement in which we proposed an early diagnosis and multidisciplinary treatment to avoid severe aesthetic or functional damages.

Análise de impacto orçamentário de dispositivos contraceptivos na saúde suplementar brasileira / Budget impact analysis of contraceptive devices on Brazilian supplementary health

Objetivo: Analisar o impacto orçamentário da adoção de dispositivos contraceptivos reversíveis de longa duração em uma operadora de plano de saúde localizada no Sul do Brasil. Especificamente, analisamos a incorporação do implante subdérmico de etonogestrel (Implanon®) como alternativa ao sistema intrauterino de levonorgestrel (DIU Mirena® ou DIU Kyleena®), ao longo de um período de 15 anos. Métodos: Realizamos uma análise do impacto orçamentário incremental, considerando a inclusão gradual do implante subdérmico de etonogestrel. Foram considerados dados de uma operadora de planos de saúde com mais de 600.000 beneficiários. O horizonte temporal de 15 anos permitiu uma avaliação abrangente dos efeitos financeiros. Resultados: Identificamos 5.345 pacientes elegíveis para a utilização de contraceptivos reversíveis de longa duração. No cenário em que somente o sistema intrauterino de levonorgestrel era adotado, projetou-se um impacto orçamentário total de R$ 746.379.857,80 ao longo de 15 anos. No cenário alternativo, com a incorporação gradual do implante subdérmico, o impacto orçamentário total foi calculado em R$ 689.800.196,83. Isso resultou em um impacto orçamentário incremental negativo de -R$ 56.579.660,97 ao longo do período. Conclusão: A análise de impacto orçamentário realizada indica um potencial benefício financeiro ao adotar o implante subdérmico de etonogestrel como alternativa ao sistema intrauterino de levonorgestrel para contracepção. Esse achado sugere possíveis reduções de custos na área de saúde suplementar no Brasil, reforçando a importância de avaliar opções economicamente viáveis.

Objective: To analyze the budgetary impact of the adoption of long-acting reversible contraceptive devices in a health plan operator located in southern Brazil. Specifically, we analyzed the incorporation of the etonogestrel subdermal implant (Implanon®) as an alternative to the levonorgestrel intrauterine system (Mirena® IUD or Kyleena® IUD), over a period of 15 years. Methods: We performed an analysis of the incremental budgetary impact, considering the gradual inclusion of the etonogestrel subdermal implant. Data from a health plan operator with more than 600,000 beneficiaries were considered. The 15-year time horizon allowed for a comprehensive assessment of the financial effects. Results: We identified 5,345 patients eligible for the use of long-acting reversible contraceptives. In the scenario where only the levonorgestrel intrauterine system was adopted, a total budget impact of BRL 746,379,857.80 was projected over 15 years. In the alternative scenario, with the gradual incorporation of the subdermal implant, the total budgetary impact was calculated at BRL 689,800,196.83. This resulted in a negative incremental budgetary impact of -R$56,579,660.97 over the period. Conclusion: The budget impact analysis carried out indicates a potential financial benefit in adopting the etonogestrel subdermal implant as an alternative to the levonorgestrel intrauterine system for contraception. This finding suggests possible cost reductions in the supplementary healthcare area in Brazil, reinforcing the importance of evaluating economically viable options.

Acceptability and continuation of use of the subdermal contraceptive implant among adolescents and young women in Argentina: a retrospective cohort study.

A new public policy was instituted in Argentina for free distribution of subdermal contraceptive implants to women aged 15-24 years old in the public healthcare system. The objective of this study is to determine the extent to which this population adhered to the implant, as well as predictors of continuation. The retrospective cohort study was based on a telephone survey of a random sample of 1101 Ministry of Health-registered implant users concerning the continuation of use, satisfaction with the method and side-effects, and reasons for removal. Descriptive statistics and multivariate regression analysis were used to explore the association between adherence and having received contraceptive counselling, satisfaction, and side effects. We found high levels of adherence (87%) and satisfaction (94%). Common reported side effects were amenorrhoea or infrequent bleeding, perceived weight gain, increased menstrual bleeding and headaches. Multivariate regression analysis indicates that, among adolescents, having received contraceptive counselling increased comfort, while frequent bleeding at six months hindered trust. Participants who had a history of a prior delivery or who had themselves primarily chosen the method were less likely to request the removal of the implant. Our results support the public policy of free implant distribution in the public health sector. This is a sustainable public policy that contributes to equity and access to effective contraception. It is appropriate for adolescents and young women and will also reduce unintended pregnancies. Our results suggest that counselling patients is key prior to insertion of the implant, as it improves acceptability and continuation.

Vitrectomized vs non-vitrectomized eyes in DEX implant treatment for DMO-Is there any difference? the VITDEX study.

OBJECTIVE: We aimed to compare visual and anatomical outcome in vitrectomized and non-vitrectomized eyes treated with dexamethasone (DEX) implant due to diabetic macular oedema (DMO). DESIGN: Multicenter, retrospective, interventional study. PARTICIPANTS: 236 eyes from 234 patients with DMO with or without previous vitrectomy performed with follow-up of 12 months. METHODS: Records were reviewed for cases of DMO treated with DEX implant in vitrectomized and not vitrectomized eyes. Best corrected visual acuity (BCVA), central subfoveal thickness (CST), and intraocular pressure (IOP) were recorded at baseline and 12 months after treatment with DEX implants. Correlations between vitreous status and visual and anatomical outcome, as well as safety profile were analysed. MAIN OUTCOME MEASURES: BCVA and CST over follow-up period. SECONDARY OUTCOMES: cataract rate formation, intraocular pressure increase, number of implants needed. RESULTS: The non-vitrectomized group included 130 eyes (55.1%), the vitrectomized group included 106 eyes (44.9%). The groups were well balanced for age and gender (p = 0.540, and p = 0.053, respectively). Both groups showed statistically significant improvement in BCVA and CST (for all groups: p < 0.001). There was no significant difference between the groups in terms of change in vision (p = 0.89) and anatomy (p = 0.65). The mean number of DEX implants given during follow-up was 3.5 in both groups, and there was no significant difference between the groups (p = 0.81). CONCLUSION: We demonstrated similar anatomical and functional efficacy of DEX implant in non-vitrectomized and vitrectomized eyes. Its efficacy was not influenced by full vitrectomy for diabetic retinopathy complications. Safety profile was well balanced between groups.

A slow-release dexamethasone implant for cancer-associated retinopathy.

This case report aims to show the anatomical and functional results of a patient diagnosed as having cancer-associated retinopathy treated with a controlled-release dexamethasone implant (Ozurdex). Anatomical outcomes were assessed using spectral domain optical coherence tomography; and functional outcomes, by measuring visual acuity, microperimetry, and mutifocal electroretinography. The follow-up period was 1 year.

Prospective evaluation of the effectiveness of combined treatment of macular edema secondary to retinal vein occlusion with intravitreal bevacizumab and dexamethasone implants.

PURPOSE: To evaluate the effectiveness of in---travitreal bevacizumab injections following a single dexamethasone implant in the treatment of macular edema secondary to branch and central retinal vein occlusion. METHODS: This was a prospective interventional non-comparative study, 44 eyes of patients with naïve macular edema related to branch and central retinal vein occlusion were treated with a dexamethasone implant. Patients were followed-up at four-week intervals from the second to the sixth month. If persistent or recurrent macular edema occurred during this period, the patient was treated with intravitreal bevacizumab injections on an as-needed basis. The outcome measures were best-corrected visual acuity and central macular thickness changes. RESULTS: The mean best-corrected visual acuity changed from 0.97 ± 0.33 LogMAR at baseline to 0.54 ± 0.40 at the six-month post-implant examination (p<0.00001). Improvement ≥3 Snellen lines were seen in 20 eyes (45.54%). The mean central macular thickness at baseline was 670.25 ± 209.9 microns. This had decreased to 317.43 ± 112.68 microns at the six-month follow-up (p<0.00001). The mean number of intravitreal bevacizumab injections received in the six months post-implant was 2.32. The mean time from dexamethasone implant to first anti-VEGF injection was 3.45 months. CONCLUSIONS: Intravitreal bevacizumab injections following a single dexamethasone implant were found to improve best-corrected visual acuity and central macular thickness in patients with macular edema due to branch and central retinal vein occlusion at six months, with few intravitreal injections required.

One-year follow-up of immediate postpartum contraceptive implant insertion in adolescents.

PURPOSE: Our study aimed to evaluate the acceptability, adverse effects and continuation rates among adolescents who accepted the etonogestrel (ENG) subdermal implant and compared to adolescents who chose other methods during the immediate postpartum period before hospital discharge, with one year follow-up up. MATERIALS AND METHODS: We conducted a cohort non-randomised study at the Women's Hospital, University of Campinas. All women up to 19 years of age, who gave birth at the hospital between July 2019 and April 2020, were invited to participate and were offered the ENG-implant or the routine contraceptive methods. They were followed for one year postpartum. RESULTS: We included 100 teenagers and 72 accepted the ENG-implant. Students are more likely to accept the ENG-implant than non-students (PR: 1.25 [95%CI 0.99-1.59]). Up to one year of follow-up, survival analysis showed that the time of adherence to the method was longer for the ENG-implant users (p = 0.0049). More than 90% of the adolescents were satisfied with the implant; however, five requested early removal due to menstrual irregularity and local discomfort. CONCLUSION: Provision ENG-implant for adolescents in the immediate postpartum demonstrated high acceptance and ensured effective contraception. After one year, most of them were satisfied, with a high continuation rate and without unplanned pregnancies.

Etonogestrel-releasing contraceptive implant in a patient using thalidomide for the treatment of erythema nodosum leprosum: a case report.

INTRODUCTION: Thalidomide is an immunomodulatory drug and first choice in the treatment of erythema nodosum leprosum. Given its teratogenic potential, it is essential that an effective contraceptive method is used, especially a long-acting reversible contraceptive (LARC) method. The subdermal etonogestrel (ENG)-releasing implant is an adequate method due to the high effectiveness and long-term use. However, interaction between thalidomide and ENG has not been well documented. Concern arises because thalidomide interacts with cytochrome P450 (CYP450) enzymes that metabolize sexual steroids. AIM: We aimed to study the effectiveness and safety of the ENG-implant in a thalidomide user. METHODS: Case report of a sexually active 21-year-old patient with both Hansen's disease and leprosy reaction type 2 treated with thalidomide requiring effective contraception. Follow-up was up to 36 months after implant placement. RESULTS: Contraception with ENG-implant was effective and safe, based on clinical parameters (reduction of menstrual flow and cervical mucus thickening) and laboratory parameters (gonadotropins and sexual steroids). CONCLUSION: To the best of our knowledge, this is the first case reported which presents a patient in simultaneous use of thalidomide and ENG-implant. Although this case report preliminary supports effectiveness and safety of ENG-implant as a contraceptive option in women using thalidomide, rigorous drug-drug interaction research is needed to better characterize the interaction between thalidomide and the ENG-implant.

Trends in subdermal contraceptive implant use in Mexico 2009-2018: A population-based study.

OBJECTIVE: To describe subdermal implant use in Mexico over time, by state and by age. METHODS: We conducted a repeated cross-sectional study using the 2009, 2014, and 2018 waves of the National Survey of Demographic Dynamics (Encuesta Nacional de la Dinámica Demográfica [ENADID]). Our outcome was current use of contraception, by type, with a focus on the implant. We used visualizations, descriptive and bivariate statistics, and multinomial models to assess change over time, geographic patterns, method mix, and factors associated with implant use (vs intrauterine device [IUD] or other hormonal methods). RESULTS: Implant use is increasing over time in Mexico, from 1.1% of women who have ever used a method in 2009 to 4.5% in 2018 (P < 0.001); the change is greatest among adolescents (2.5% in 2009 to 12.2% in 2018; P < 0.001). Change in implant use as a fraction of modern method use was heterogeneous across Mexican states. The adjusted relative likelihood of using an implant compared with IUD was 34% higher for adolescents compared with women aged 20-29 years (relative risk ratio 1.34, 95% confidence interval 1.16-1.55, P < 0.001), controlling for other variables in the model. CONCLUSION: Use of subdermal implants is increasing over time in Mexico and is concentrated among adolescents. Implants have the potential to expand access to highly effective contraception in Mexico.

SURGICAL REMOVAL AFTER IATROGENIC SUBRETINAL INJECTION OF AN INTRAVITREAL DEXAMETHASONE IMPLANT.

PURPOSE: To report a rare case of subretinal migration of an intravitreal dexamethasone implant to treat macular edema secondary to diabetic retinopathy in a vitrectomized eye and the surgical outcome. OBSERVATIONS: A pars plana vitrectomy and a retinotomy were performed to remove the implant and restore vision. CONCLUSION AND IMPORTANCE: Subretinal dislodgement of intravitreal implants is a rare and preventable complication. In the current case, we speculated that this complication might have been related to the injection technique, a possible unrecognized retinal perforation before the injection of the implant, or delayed treatment with the implant. Because a retinal detachment and vitreoretinal proliferation were observed, surgical management was required. Increasing widespread application of any technology may lead to a more significant risk of complications, and ophthalmologists should be aware of this potential risk.

Manejo farmacológico del sangrado irregular no menstrual asociado al uso de implantes anticonceptivos subdérmicos / Pharmacological management of irregular non-menstrual bleeding associated with the use of subdermal contraceptive implants

El spottingo sangrado irregular no menstrual es uno de los principales efectos secundarios de los implantes anticonceptivos, situación que se recomienda discutir con la usuaria previo a la colocación, para evitar falsas expectativas o temores que lleven a la extracción temprana del dispositivo. A propósito de una paciente sin antecedentes relevantes que consultó al centro de salud por spotting desde la colocación del implante cuatro meses antes, decidimos revisar la evidencia sobre la efectividad de los distintos esquemas farmacológicos disponibles para el manejo de este evento adverso. Luego de realizar una búsqueda bibliográfica concluimos que, si bien existe sustento para indicar algunos de los esquemas farmacológicos, este es aún débil y son necesarios estudios clínicos adicionales que brinden evidencia sólida sobre qué esquema en particular utilizar, evaluando sus riesgos y beneficios. (AU)

Spotting or irregular non-menstrual bleeding is one of the main side effects of contraceptive implants, a situation that health professionals must discuss with the user prior to its placement in order to avoid false expectations or fears that lead to early removal of the implant. Regarding a patient with no relevant history who consulted the health center due to spotting four months after implant placement, we decided to review the evidence onthe effectiveness on different pharmacological schemes available for the management of this adverse event. After performing a literature search, we concluded that, although there is support for indicating some of the pharmacological schemes, this is still weak, and further clinical studies are needed to provide solid evidence on which particular scheme touse, assessing its risks and benefits.

"Tabela Periódica" da Anticoncepção ­ uma ferramenta na escolha contraceptiva / "Periodic Table" of Contraception ­ a tool in the contraceptive choice

Estima-se que 40% das gestações no mundo sejam não planejadas. Em países de baixa renda, complicações no parto são a maior causa de morte entre mulheres de 15 a 19 anos. A disponibilidade de métodos contraceptivos reversíveis é necessária para o adequado planejamento reprodutivo. Entre os métodos reversíveis, os de longa ação (LARCs) são os mais efetivos. Métodos de curta ação (SARCs) são preferenciais para pacientes que desejam gestar a curto prazo e para as quais a gestação não será indesejada. O presente estudo é uma revisão narrativa da literatura, de artigos em inglês e português publicados entre 2009 e 2020, utilizando as bases de dados SciELO, Medline e Embase. O objetivo desta revisão é apresentar os LARCs e SARCs em uma tabela com dados comparativos que auxiliem na tomada de decisão do médico e da paciente e permita estabelecer estratégias para um planejamento familiar adequado.(AU)

It is estimated that 40% of pregnancies in the world are unplanned. In low-income countries, complications in childbirth are the major cause of death among women aged 15 to 19 years. The availability of reversible contraceptive methods is necessary for proper reproductive planning. Among the reversible methods, long-acting reversible contraception (LARCs) is the most effective. Short-acting reversible contraception (SARCs) methods are preferred for patients who wish to become pregnant in the short term and for whom pregnancy will not be undesirable. The present study is a narrative review of the literature, of articles in English and Portuguese published between 2009 and 2020, using the databases SciELO, Medline and Embase. The purpose of this review is to present the LARCs and SARCs in a table with comparative data that assist in the decision making of the doctor and the patient and allow to establish strategies for adequate family planning.(AU)

Implante de testosterona para la mujer, evaluación de seguridad y efectividad en esta vía de administración / Testosterone implant for women, evaluation of safety and effectiveness in this route of administration

INTRODUCCIÓN Y OBJETIVO: El rol de la testosterona exógena en la función sexual femenina ha sido estudiado durante muchos años, con resultados contradictorios. En el último tiempo se ha promovido el uso de pellets de testosterona como una solución para mejorar la libido femenina, la cognición, la fuerza muscular y los sistemas cardiovascular y óseo, e incluso evitar el envejecimiento. Por ello, revisamos las publicaciones para tratar de responder si esto es una moda o el tratamiento más innovador del último tiempo. MÉTODO: Se analizaron las bases de datos PubMed/Medline, Trip Database, Cochrane, SciELO, Scopus, UpToDate, Ovid, ProQuest, Science Direct y ResearchGate. RESULTADOS: De acuerdo con la evidencia, la mejor testosterona disponible es la transdérmica y debe ser usada solo en el trastorno del deseo sexual hipoactivo (TDSH). Los trabajos que evalúan los pellets de testosterona tienen sesgos metodológicos importantes. Si bien son útiles para mejorar la función sexual femenina, producen concentraciones plasmáticas suprafisiológicas de testosterona, por lo que no se puede establecer su seguridad a largo plazo. Tampoco hay datos suficientes que avalen su uso para mejorar el rendimiento cognitivo y el bienestar general, en el tratamiento de enfermedades cardiovasculares o en la prevención de enfermedad ósea. CONCLUSIONES: La testosterona solo se recomienda en el tratamiento del TDSH por vía transdérmica. No recomendamos el uso de pellets de testosterona para el tratamiento de la disfunción sexual ni como hormona antienvejecimiento, ya que no hay estudios consistentes sobre su seguridad, eficacia y efectos adversos a largo plazo.

INTRODUCTION AND OBJECTIVE: The role of exogenous testosterone in female sexual function has been studied for many years with contradictory results. In recent times, the use of testosterone pellets has been promoted as a solution to improve female libido, cognition, muscle strength, cardiovascular system, bone and even prevent aging. Therefore, we will review the publications in order to answer whether this is a fad or the most innovative treatment of recent times. METHOD: The databases PubMed/Medline, Trip Database, Cochrane, SciELO, Scopus, UpToDate, Ovid, ProQuest, Science Direct and ResearchGate were analyzed. RESULTS: So far, the evidence best testosterone available is transdermal testosterone and that it should be used only in hypoactive sexual desire disorder (HSDD). Papers evaluating testosterone pellets have significant methodological biases. While they are useful in improving female sexual function, they produce supra-physiological plasma levels of testosterone, so their long-term safety cannot be established. There is also insufficient data to support their use in improving cognitive performance and general well-being, treatment of cardiovascular disease or prevention of bone disease. CONCLUSIONS: Testosterone is only recommended for the tratment of HSDD via the transdermal route. We do not recommended the use of testosterone pellets for the treatment of sexual dysfunction or as an anti aging hormone, as there are no consistent studies on its safety, efficacy, and long-term adverse effects.

Practical training of health care providers in insertion of contraceptive implants: findings from two Brazilian centres.

BACKGROUND AND OBJECTIVES: Lack of information and myths or inadequate training of health care providers in the guidance and management of contraceptives could negatively affect choice and eventually continuation rates. Our objectives were to evaluate the impact of clinical and theoretical training of health care professionals on insertion and removal of etonogestrel (ENG)-implant regarding this contraceptive, including pre- and post-training knowledge about insertion and removal techniques, clinical characteristics, side effects and outcomes. MATERIAL AND METHODS: We conducted a cross-sectional study in which a questionnaire was sent to health care providers after they received clinical training in the management of ENG-implant. RESULTS: After training, 78.2% of the 139 participants initiated to offer and inserted up to 5 implants/month and 17.6% between 6 to 10/month. None of the interviewees reported having difficulty with insertions after training, and 87.9% reported feeling very confident for removal. CONCLUSION: Theoretical and practical training appeared important to prepare health care professionals, clarify doubts and promote higher rates of use of contraceptive implants in Brazil, contributing to reduce the rates of unintended pregnancies.

One-year incidence of low libido in women using levonorgestrel subdermal implant as contraception. Cohort study. Armenia, Colombia, 2014-2019 / [Incidencia a un año de deseo sexual hipoactivo en mujeres que planifican con implante subdérmico de levonorgestrel. Estudio de cohorte. Armenia, Colombia, 2014-2019].

Objective: To determine the incidence of low libido in women using the levonorgestrel (LNG) subdermal implant for contraception after 12 months and to identify other adverse effects. Materials and methods: Cohort study that included women over the age of 18, with no children or prior gestations and in a stable relationship, with an LNG implant inserted at least three months before in a private teaching hospital in Armenia (Quindío), Colombia, between 2014 and 2019. Women with a history of sexual dysfunction, sexually transmitted infections in the past six months, weighing more than 89 kg and difficult to follow were excluded. Consecutive sampling was used. The characteristics of the study population were described, the cumulative incidence of low libido and the adverse effects related to the LNG subdermal implant after 12 months of follow-up were estimated. The tool used was the Female Sexual Dysfunction Index (FSFI). Descriptive statistics were applied. Results: The participants were 238 women with a mean age of 24.69 (SD ± 5.82) years. An 18.82% incidence of low libido was found. In 60.25% of the women were diagnosed with low libido in the first 6 months of follow-up. Adverse effects manifested as early as 3 months after the insertion of the implant, the most frequent being irregular bleeding (62.34%), followed by amenorrhea (38.91%) and weight gain (33.89%). Conclusions: It is important for practitioners and users to become aware of the presence of low libido disorder and the adverse events that may occur with the use of the levonorgestrel subdermal implant. Future research is required to confirm these findings and the underlying physiological cause.

Objetivo: definir la incidencia de deseo sexual hipoactivo (DSH) en mujeres que planifican con el implante subdérmico de levonorgestrel (LNG) después de 12 meses, y conocer otros efectos adversos. Materiales y métodos: estudio de cohorte, cuyas participantes fueron mujeres mayores de 18 años sin hijos ni embarazos previos y con pareja estable, a quienes se les había insertado el implante de LNG al menos tres meses previos en una clínica privada de carácter universitario en Armenia (Quindío), Colombia, entre 2014 y 2019. Se excluyeron mujeres con antecedentes de disfunción sexual, infecciones de transmisión sexual en los últimos 6 meses, peso mayor a 89 Kg y dificultades para el seguimiento. El muestreo fue consecutivo. Se describieron las características de la población estudiada, se estimó la incidencia acumulada de DSH y efectos adversos relacionados con el implante subdérmico de LNG a 12 meses de seguimiento. Se aplicó como instrumento el Índice de Función Sexual Femenino. Se utilizó estadística descriptiva. Resultados: participaron 238 mujeres cuya edad media fue de 24,69 (DE ± 5,82) años. Se determinó una incidencia de deseo sexual hipoactivo del 18,82%. El 60,25% de las mujeres fueron diagnosticadas con DHS en los primeros 6 meses de seguimiento. Los efectos adversos se hicieron presentes desde los primeros 3 meses de la inserción del implante, el sangrado irregular (62,34%) fue el más frecuente, seguido de la amenorrea (38,91%) y el aumento de peso (33,89%). Conclusiones: es importante que los médicos y las usuarias se informen sobre la presencia del trastorno de deseo sexual hipoactivo y los efectos adversos que pueden surgir con el uso del implante subdérmico de levonorgestrel. Las futuras investigaciones deben confirmar estos hallazgos, así como su eventual base fisiológica.
