RESUMO

BACKGROUND: The etonogestrel contraceptive implant is currently approved by the United States Food and Drug Administration (FDA) for the prevention of pregnancy up to 3 years. However, studies that suggest efficacy up to 5 years. There is little information on the prevalence of extended use and the factors that influence clinicians in offering extended use. We investigated clinician perspectives on the barriers and facilitators to offering extended use of the contraceptive implant. METHODS: Using the Consolidated Framework for Implementation Research (CFIR), we conducted semi-structured qualitative interviews. Participants were recruited from a nationwide survey study of reproductive health clinicians on their knowledge and perspective of extended use of the contraceptive implant. To optimize the diversity of perspectives, we purposefully sampled participants from this study. We used content analysis and consensual qualitative research methods to inform our coding and data analysis. Themes arose deductively and inductively. RESULTS: We interviewed 20 clinicians including advance practice clinicians, family medicine physicians, obstetrician/gynecologist and complex family planning sub-specialists. Themes regarding barriers and facilitators to extended use of the contraceptive implant emerged. Barriers included the FDA approval for 3 years and clinician concern about liability in the context of off-label use of the contraceptive implant. Educational materials and a champion of extended use were facilitators. CONCLUSIONS: There is opportunity to expand access to extended use of the contraceptive implant by developing educational materials for clinicians and patients, identifying a champion of extended use, and providing information on extended use prior to replacement appointments at 3 years.

RESUMO

INTRODUCTION: Migration is a rare but serious complication of the etonogestrel contraceptive implant, and little is known about its extent. PURPOSE: To document and characterise cases of etonogestrel contraceptive implant migration in the scientific literature. METHODS: A systematic review of Medline, Embase and Global Health databases was carried out between January 2000 and January 2023 to identify articles presenting implant migrations. Narrative reviews, conference abstracts and articles not written in English or French were excluded. RESULTS: Forty-five articles, mostly published since 2016, were identified (eight case series and 37 case reports), for a total of 148 independent cases of migration: in pulmonary blood vessels (n = 74), in non-pulmonary blood vessels (n = 16) and extravascular (n = 58). Many patients are asymptomatic and migration is often an incidental finding. A non-palpable implant and symptoms related to implant location (intra- or extra-vascular) may be indicative of migration. Inadequate insertion and normal or underweight appear to increase the risk of migration. Scientific societies and authors offer practical strategies to deal with implant migration. CONCLUSION: Professionals who insert and remove contraceptive implants must be adequately trained. They need to be on the lookout for implant migration, and promptly refer patients to appropriate care if migration is suspected.


This systematic review documents and characterises 148 cases of vascular and extravascular etonogestrel contraceptive implant migration. Healthcare professionals must be aware of this rare but serious complication and be adequately trained to insert and remove contraceptive implants.

RESUMO

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.

RESUMO

BACKGROUND: Nexplanon implants are a common hormonal contraceptive modality. Though rare, these devices can embolize into the injured wall of the basilic vein, through the right heart, and finally wedge itself into a pulmonary artery. With adherence to the arterial wall over time, it becomes less amenable to endovascular retrieval. Patients may present with symptoms mimicking a pulmonary embolism, or without any symptoms at all. In asymptomatic cases, endovascular retrieval and/or surgery is required when patients wish to begin having children prior to biological inactivity. The current literature showed as little as nine case reports detailing lung tissue removal in the aim of reversing a patient's implanted contraceptive device. CASE PRESENTATION: A 22-year-old asymptomatic active-duty Caucasian female presented for elective outpatient Nexplanon removal. The suspicion of possible implant migration arose when it was discovered to be non-palpable in her left arm. After plain film x-rays failed to localize the implant, a chest x-ray and follow-up Computed Tomography (CT) scan revealed that the Nexplanon had migrated to a distal branch of the left pulmonary artery. Due to the patient's strong desires to begin having children, the decision was made for removal. Initial endovascular retrieval failed due to Nexplanon encapsulation within the arterial wall. Ultimately, the patient underwent a left video-assisted thoracoscopic surgery (VATS) for exploration and left lower lobe basilar S7-9 segmentectomy, which successfully removed the Nexplanon. CONCLUSIONS: Implanted contraceptive devices can rarely result in migration to the pulmonary vasculature. These radiopaque devices are detectable on imaging studies if patients and clinicians are unable to palpate them. An endovascular approach should be considered first to spare lung tissue and avoid chest-wall incisions, but can be complicated by encapsulation and adherence to adjacent tissue. A VATS procedure with single-lung ventilation via a double-lumen endotracheal tube allows surgeons to safely operate on an immobilized lung while anesthesiologists facilitate single-lung ventilation. This patient's case details the uncommon phenomenon of Nexplanon migration, and the exceedingly rare treatment resolution of lung resection to remove an embolized device.

RESUMO

AIMS: The current work describes the development of mechanistic vaginal absorption and metabolism model within Simcyp Simulator to predict systemic concentrations following vaginal application of ring and gel formulations. METHODS: Vaginal and cervix physiology parameters were incorporated in the model development. The study highlights the model assumptions including simulation results comparing systemic concentrations of 5 different compounds, namely, dapivirine, tenofovir, lidocaine, ethinylestradiol and etonogestrel, administered as vaginal ring or gel. Due to lack of data, the vaginal absorption parameters were calculated based on assumptions or optimized. The model uses release rate/in vitro release profiles with formulation characteristics to predict drug mass transfer across vaginal tissue into the systemic circulation. RESULTS: For lidocaine and tenofovir vaginal gel, the predicted to observed AUC0-t and Cmax ratios were well within 2-fold error limits. The average fold error (AFE) and absolute AFE indicating bias and precision of predictions range from 0.62 to 1.61. For dapivirine, the pharmacokinetic parameters are under and overpredicted in some studies due to lack of formulation composition details and relevance of release rate used in ring model. The predicted to observed AUC0-t and Cmax ratios were well within 2-fold error limits for etonogestrel and ethinylestradiol vaginal ring (AFEs and absolute AFEs from 0.84 to 1.83). CONCLUSION: The current study provides first of its kind physiologically based pharmacokinetic framework integrating physiology, population and formulation data to carry out in silico mechanistic vaginal absorption studies, with the potential for virtual bioequivalence assessment in the future.

RESUMO

OBJECTIVES: To assess the pharmacokinetics and pharmacodynamics of the etonogestrel (ENG) contraceptive implant when inserted at an alternative scapular site. STUDY DESIGN: We conducted a pilot study of healthy, reproductive-age females who underwent subdermal insertion of an ENG implant over the inferior edge of the nondominant scapula (scapular insertion). We measured serum ENG levels over 1 year at nine time points. Participants completed questionnaires on insertion site and bleeding side effects. We collected photographs and video recordings of insertion and removal techniques. RESULTS: We enrolled five participants (as prespecified), their median age was 26.0 years (range: 19.6-30.3), and median body mass index was 25.0 kg/m2 (range: 22.0-28.0). All serum ENG concentrations remained >90 pg/mL and were within the range of published data for arm insertion of ENG implant at all time points. The mean serum ENG level was 511.7 pg/mL (±168.2) at 1 week and 136.6 pg/mL (±21.8) at 12 months. During the first week after insertion, four of five participants noted insertion site pain with a median pain score of 2 (range 1-3), but all noted resolution by week two. Participants reported variable bleeding patterns consistent with standard ENG implant placement. At the end of the study, all participants reported satisfaction with the implant and would recommend scapular insertion to a friend. CONCLUSIONS: Scapular insertion of the ENG contraceptive implant has similar pharmacokinetics to arm insertion over 1 year of use. This novel, alternative site was well tolerated and demonstrated similar bleeding side effects to standard arm insertion. IMPLICATIONS: Subdermal scapular insertion of the etonogestrel contraceptive implant demonstrated similar pharmacokinetics to arm insertion over 1 year of use. Our pilot data support scapular insertion as an alternative site for ENG contraceptive implants, which could be beneficial for certain patient populations.

RESUMO

OBJECTIVES: To examine the prevalence of menstrual irregularities, side effects, and discontinuation rates of etonogestrel subdermal implants (ESI) in women attending King Abdulaziz Medical City, Jeddah, Saudi Arabia. METHODS: This cross-sectional was carried out based on electronic medical records and a phone-based questionnaire administered to women who underwent ESI insertion in a single tertiary care hospital in Jeddah, Saudi Arabia, between 2019 and 2022. The primary objective was the prevalence of menstrual abnormalities. The secondary study objective included the discontinuation rate, reasons for discontinuation, and ESI side effects. RESULTS: In total, 345 women with ESI were included in this study. The prevalence of any type of menstrual abnormalities was 88%. Other side effects included skin and mood changes, arm pain, and numbness. The discontinuation rate was 11% in the first year and 22% before the completion of 36 months. CONCLUSION: Although menstrual abnormalities are a common side effect of ESI, only 22% of users discontinued this method of contraception.

RESUMO

High rates of unplanned pregnancies persist despite pharmacological developments and advancements in contraceptive methods. Here, we demonstrate that the etonogestrel-releasing subdermal contraceptive implant (IMP-ETN) may be an appropriate and cost-effective alternative to levonorgestrel-releasing intrauterine systems (LNG-IUSs) for women in Brazil. For our pharmacoeconomic analysis, we reviewed the literature on IMP-ETN regarding its acceptance, eligibility criteria, choice, relations with age, adverse events and, finally, the unmet need in the fee-for-service private healthcare sector. We considered qualitative observations in combination with quantitative analysis and performed a deterministic sensitivity analysis to investigate whether this technology can be self-sustainable over a period of five years. The target population for this analysis comprised 158,696 women. Compared with the continued use of LNG-IUSs, adopting the IMP-ETN can result in a cost avoidance of $ 7.640.804,02 in the first year and $ 82,455,254.43 in five years. Disseminating information among physicians will promote this change and strengthen the potential cost avoided by private health system payers. These savings can be used to improve other healthcare programs and strategies. Moreover, the principles of care can be promoted by improving and adapting healthcare systems and expanding treatment and follow-up strategies. This would also provide support to women's reproductive rights and improve their quality of life. Our results suggest that the IMP-ETN has a favorable cost-effectiveness profile. Given all its advantages and negative incremental cost impact over a period of five years, the IMP-ETN may be a more favorable alternative to LNG-IUSs. Therefore, it should be offered to beneficiaries with a private healthcare plan. This analysis overcomes previous barriers to the use of cost-benefit models, and our results may help balance decision-making by policymakers, technical consultants, and researchers.

RESUMO

OBJECTIVE: Clinical factors related to development of amenorrhea in adolescents with the etonogestrel contraceptive implant are not well-understood. The purpose of this study is to describe what baseline clinical characteristics are associated with amenorrhea in adolescents with a contraceptive implant 12 months after placement. STUDY DESIGN: This retrospective cohort study included 252 post-menarchal individuals aged 12-22 years with a contraceptive implant placed between 2016-2020. Data abstracted at insertion, three months post-insertion, and 12 months post-insertion included demographics, baseline bleeding pattern, prior contraception use, post-insertion bleeding pattern, and method discontinuation. We assessed possible predictive characteristics of our outcomes using bivariate and multivariable logistic regression analyses. RESULTS: Twenty nine percent of patients were amenorrheic 12 months after placement. Patients who were amenorrheic at 12 months were more likely to be obese (41.1% vs 24.6%, p = 0.01), to have been amenorrheic prior to implant insertion (16.9% vs 5.4%, p < 0.01, to have used hormonal contraception immediately prior to insertion (42.5% vs 26.3%, p = 0.01), to have had the most recent contraceptive method being another implant (12.3% vs 3.6%, p = 0.02), and to have developed amenorrhea within three months after placement (22.2% vs 12.6%, p < 0.01). After multivariable regression analysis, only obesity (adjusted odds ratio [aOR] 2.2 95% CI 1.1-4.2) and amenorrhea at three months (aOR 3.6, CI 1.1-11.5) were associated with amenorrhea at 12 months. CONCLUSION: Obesity and early amenorrhea were associated with 12-month amenorrhea in adolescents using the etonogestrel subdermal implant. Understanding this can help with contraceptive method selection and counseling for patients and providers. IMPLICATIONS: Obesity and early amenorrhea with the etonogestrel contraceptive implant are associated with longer-term amenorrhea in adolescents using this method. These findings can aid providers with method selection and pre-insertion decision-making for adolescents considering contraceptive implant use, as well as continued counseling after placement.

RESUMO

After a fortuitous observation of two cases of chemosensitivity recovery in women with congenital central hypoventilation syndrome (CCHS) who took desogestrel, we aimed to evaluate the ventilatory response to hypercapnia of five CCHS patients with or without treatment consisting of desogestrel (DESO) or levonorgestrel (LEVO). Only two patients became responsive to hypercapnia under treatment, according to their basal vagal heart rate variability. These results suggest that heart rate variability may be promising tool to discriminate patients susceptible to become responsive to hypercapnia under DESO-LEVO treatment.Clinical Trials Identifier NCT01243697.

RESUMO

AIM: The central CO2 chemoreflex is a vital component of respiratory control networks, providing excitatory drive during resting conditions and challenges to blood gas homeostasis. The retrotrapezoid nucleus is a crucial hub for CO2 chemosensitivity; its ablation or inhibition attenuates CO2 chemoreflexes and diminishes restful breathing. Similar phenotypes characterize certain hypoventilation syndromes, suggesting underlying retrotrapezoid nucleus impairment in these disorders. Progesterone stimulates restful breathing and CO2 chemoreflexes. However, its mechanisms and sites of actions remain unknown and the experimental use of synthetic progestins in patients and animal models have been met with mixed respiratory outcomes. METHODS: We investigated whether acute or chronic administration of the progestinic drug, etonogestrel, could rescue respiratory chemoreflexes following selective lesion of the retrotrapezoid nucleus with saporin toxin. Adult female Sprague Dawley rats were grouped based on lesion size determined by the number of surviving chemosensitive neurons, and ventilatory responses were measured by whole body plethysmography. RESULTS: Ventilatory responses to hypercapnia (but not hypoxia) were compromised in a lesion-dependent manner. Chronic etonogestrel treatment improved CO2 chemosensitivity selectively in rats with moderate lesion, suggesting that a residual number of chemosensitive neurons are required for etonogestrel-induced CO2 chemoreflex recovery. CONCLUSION: This study provides new evidence for the use of progestins as respiratory stimulants under conditions of central hypoventilation and provides a new testable model for assessing the mechanism of action of progestins in the respiratory network.

RESUMO

OBJECTIVE: To estimate the incidence of ovulation suppression within five days of etonogestrel 68 mg implant insertion in the presence of a dominant follicle with and without same-day ulipristal acetate. STUDY DESIGN: This single site non-masked, exploratory randomized trial recruited people age 18-35 years with regular menstrual cycles, no pregnancy risk, and confirmed ovulatory function. We initiated transvaginal ultrasound examinations on menstrual day 7-9 and randomized participants 1:1 to etonogestrel implant alone or with concomitant ulipristal acetate 30 mg oral when a dominant follicle reached ≥14 mm in diameter. We completed daily sonography and serum hormone levels for up to seven days or transitioned to labs alone if sonographic follicular rupture occurred. We defined ovulation as follicular rupture followed by progesterone >3 ng/mL. We calculated point estimates, risk ratios and 95% confidence intervals for ovulation for each group. Ovulation suppression of ≥44% in either group (the follicular rupture suppression rate with oral levonorgestrel emergency contraception), would prompt future method testing. RESULTS: From October 2020 to October 2022, we enrolled 40 people and 39 completed primary outcome assessments: 20 with etonogestrel implant alone (mean follicular size at randomization: 15.2 mm ± 0.9 mm) and 19 with etonogestrel implant + ulipristal acetate (mean follicular size at randomization: 15.4 mm ± 1.2 mm, p = 0.6). Ovulation suppression occurred in 13 (65%) of etonogestrel implant-alone participants (Risk ratio 0.6 (95% CI: 0.3, 1.1), p = 0.08) and seven (37%) of implant + ulipristal acetate participants. CONCLUSIONS: Ovulation suppression of the etonogestrel implant alone exceeds threshold testing for future research while the implant + ulipristal acetate does not. IMPLICATIONS: Data are lacking on midcycle ovulation suppression for the etonogestrel implant with and without oral ulipristal acetate. In this exploratory study, ovulation suppression occurred in 65% of implant participants and 37% of implant + ulipristal acetate participants. Ovulation suppression of the implant alone exceeds threshold testing for future emergency contraception research.

RESUMO

The injectable progestin depot-medroxyprogesterone acetate (DMPA) is a popular contraceptive choice in sub-Saharan Africa although mouse models indicate it weakens genital epithelial integrity and barrier function and increases susceptibility to genital infection. The intravaginal ring NuvaRing® is another contraceptive option that like DMPA suppresses hypothalamic pituitary ovarian (HPO) axis function with local release of progestin (etonogestrel) and estrogen (ethinyl estradiol). As we previously reported that treating mice with DMPA and estrogen averts the loss of genital epithelial integrity and barrier function induced by DMPA alone, in the current investigation we compared genital levels of the cell-cell adhesion molecule desmoglein-1 (DSG1) and genital epithelial permeability in rhesus macaques (RM) treated with DMPA or a NuvaRing®re-sized for RM (N-IVR). While these studies demonstrated comparable inhibition of the HPO axis with DMPA or N-IVR, DMPA induced significantly lower genital DSG1 levels and greater tissue permeability to intravaginally administered low molecular mass molecules. By identifying greater compromise of genital epithelial integrity and barrier function in RM administered DMPA vs. N-IVR, our results add to the growing body of evidence that indicate DMPA weakens a fundamental mechanism of anti-pathogen host defense in the female genital tract.

RESUMO

OBJECTIVE: To determine a 1-month pregnancy rate point estimate and 95% confidence interval for guideline-supported, same-day initiation of an etonogestrel implant plus oral levonorgestrel emergency contraception. STUDY DESIGN: In this single-arm, prospective observational study, all emergency contraception clients who presented to four Planned Parenthood Association of Utah clinics from February 2021 to March 2023 received information about oral levonorgestrel with same-day etonogestrel implant insertion. Participants were ≤35 years and reported unprotected intercourse within 5 days with negative pregnancy testing. The primary outcome measure was a 1-month home pregnancy test. We calculated the efficacy using a test of proportions with Yates continuity correction. RESULTS: A total of 160 emergency contraception clients (7.6% of 2106 approached) enrolled and 153 had 1-month pregnancy outcomes. A positive pregnancy test occurred in 2 participants resulting in an overall pregnancy rate of 1.32% (95% confidence interval 0.23%-5.19%). Ultrasound gestational dating assigned conception of the first pregnancy to 8 days before enrollment. For the second pregnancy, ultrasound dating designated conception at 5 days prior to enrollment. Limiting the efficacy rate to the single pregnancy that occurred within 5 days of unprotected intercourse, we report a pregnancy rate of 0.66% (95% confidence interval 0.03%-4.19%). CONCLUSIONS: In this observational study of emergency contraception clients selecting oral levonorgestrel with same-day etonogestrel implant, we identified a pregnancy rate within the established range of oral emergency contraception methods alone. IMPLICATIONS: Clients presenting for emergency contraception may also desire ongoing highly-effective contraception, yet current clinical guidelines serve as a barrier to same-day method initiation for the etonogestrel implant and other hormonal methods. Improving access to contraceptive method initiation will reduce the ongoing risk of unwanted pregnancy for this population. CLINICAL TRIAL REGISTRATION: Clinicaltrials.gov NCT04678817; registered 12/16/20.

RESUMO

OBJECTIVE: To evaluate if inter-individual variability in serum etonogestrel (ENG) concentrations accounts for variability in mood-related side effects among ENG implant users. STUDY DESIGN: Participants underwent a single-time blood draw for measurement of serum ENG concentrations using a liquid-chromatography mass-spectrometry assay, and completed a questionnaire at enrollment that retrospectively assessed mood-related side effects during the period of implant use. For a subset of participants, Patient Health Questionnaire-9 (PHQ-9) scores, obtained for other clinical purposes, were also compared. We used independent medians tests and linear regression to evaluate associations between mood symptoms and serum ENG concentrations as our primary outcome. RESULTS: Among 900 enrolled participants, 34% (306/900) reported mood changes on the baseline questionnaire. Of these, 31 (3.4%) participants also had documented PHQ-9 scores. Serum ENG concentrations (median 126.9 pg/mL [range 39.4-695.1]) were not associated with reported mood changes on the questionnaire (p = 0.19) or on the PHQ-9 (ß = 0.00, 95% CI -0.03, 0.03). CONCLUSION: Pharmacokinetic variability does not explain the inter-individual variability in mood-related side effects among ENG implant users. IMPLICATIONS: Mood-related side effects and altered mental health metrics are commonly reported by etonogestrel contraceptive implant users but demonstrate wide inter-individual variability. Individual differences in serum drug levels do not appear to account for this variability in mood-related side effects, and so future research should focus on novel personal factors.

RESUMO

Several effective contraceptive options are available for use by adolescents, including the long-acting reversible subdermal implant and intrauterine devices, which provide a high level of convenience, privacy, and effectiveness for an adolescent. Knowledge of all the effective birth control methods is essential for the pediatrician to be able to provide effective contraceptive counseling for an adolescent. An approach to counseling using a reproductive justice framework, which allows the provider and adolescent patient to engage in shared decision-making, is described. This article focuses on the long-acting reversible etonogestrel (ENG) subdermal implant for adolescents. The ENG implant is labeled for preventing pregnancy by suppressing ovulation. The ENG implant may also have a role in ameliorating dysmenorrhea and heavy menstrual bleeding. Postlabeling studies indicate that the ENG implant is effective for up to 5 years, although the device's labeling states effectivenessup to 3 years. The main contraindication to using the ENG implant is pregnancy itself. Safe initiation of the ENG implant is described, including an approach to determine whether an adolescent is pregnant. The main adverse effect of the ENG implant is an unpredictable bleeding pattern that is most often ameliorated by use of nonsteroidal anti-inflammatory medications, as well as estrogen, if not contraindicated for the patient. Details of the insertion and removal procedures, including potential complications, are described to enable the pediatrician to provide effective anticipatory guidance for the adolescent.

RESUMO

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.

RESUMO

BACKGROUND: Oral contraceptives are commonly taken by women and are known to increase the risk of venous thromboembolism (VTE). OBJECTIVE: The aim of this study was to investigate the association between oral contraceptive use and natural anticoagulants, that is, protein C (PC), protein S (PS), and antithrombin in pregnant women with deep vein thrombosis (DVT). MATERIALS AND METHODS: This case-control study was conducted on 330 pregnant women, that is, cases 165 (who used oral contraceptives) and controls 165 (who did not use oral contraceptives). The levels of PC, PS, and antithrombin were measured and compared between the two groups. The use of different types of oral contraceptives and their association with DVT and PC and PS were also analyzed. RESULTS: The study found that women with DVT had significantly lower levels of PC and PS compared with controls ( P  < 0.001). However, no significant difference was found in the levels of AT. Among the different types of oral contraceptives, first-generation progestin pills including Ethynodiol Diacetate, Norethindrone Acetate, Norethynodrel, and second-generation oral contraceptives (Lynestrenol, Levonorgestrel and Norgestrel) were not found to be associated with lower levels of PC and AT while Desogestrel, Norgestimate, and Gestodene (third-generation) were associated with lower levels of PS. CONCLUSION: This study suggests that the use of contraceptives, particularly those containing Desogestrel, Norgestimate, and Gestodene, may be associated with a higher risk of thrombosis because of the associated lower levels of PS. Monitoring anticoagulant levels is crucial in preventing DVT in this population.

RESUMO

Synthetic progestins are micropollutants of special concern, due to their growing use in human and veterinary therapies and their risks to aquatic life. Currently, there is a lack of environmental information on these compounds, worldwide. The main objective of this work was to characterize the levels of the most consumed progestins in Portugal. For that, Ria de Aveiro, Tagus estuary and Ria Formosa were sampled in a temporal perspective to evaluate levels of drospirenone (DRO), desogestrel (DSG), gestodene (GST) and levonorgestrel (LNG). Drospirenone and desogestrel were the most abundant progestins. In the North of Portugal, DSG was the most abundant (Aveiro: 193.9 ng L-1 in summer), while DRO was more representative in the South (Tagus: 178.9 ng L-1; Formosa: 125.7 ng L-1) and also in summer. These spatial differences can be associated with the hydrodynamics of each estuarine system as well as the distinct population and tourist levels associated with each site.

RESUMO

BACKGROUND: Training health extension workers on Implanon insertion offsite, or away from the workplace, can be cost-intensive, can depend on the human and financial resources of partners, and can compromise routine health services by taking health workers off the job. To address these limitations, the USAID Transform Primary Health Care Activity in Ethiopia designed an onsite Implanon insertion training at the primary health care level. This study compared and documented the implementation experience of onsite vs offsite Implanon insertion training for health extension workers. METHODS: In a mixed-method study conducted in March 2020, the team collected training data from 468 participants-half trained onsite and half offsite-and conducted key informant interviews with 20 purposively sampled individuals. The team analyzed this data, summarizing the data in tables and figures and performing a t test with p value < 0.05 using SPSS v.20. Qualitative data were analyzed manually in Excel and summarized in Word based on emerging themes. RESULTS: Health extension workers trained onsite were away from routine work an average of 3 days compared to 8 days for those trained offsite (P < 0.001). The difference in average per-trainee cost of onsite (2707 Birr = 87.3 USD) and offsite (6006 Birr = 193.7USD) training was significant (P < 0.001). There was no significant difference in mean scores of onsite and offsite trainees on the knowledge pre-test (P < 0.947) and post-test (P < 0.220) or in simulated practice on an arm model (p < 0.202). Onsite trainees, assigned to their own health post for clinical practice, performed Implanon insertions on an average of 10 clients: offsite trainees on an average of 5 clients. Most interview participants reported that the onsite Implanon training was better organized, conducted, followed up, and monitored by health centers to ensure community-level access to Implanon services, with quality and continuity. CONCLUSIONS: Onsite training is a promising approach and minimizes service interruption. It is a likely strategy for on-demand training of health extension workers and immediate assignment of skilled providers to ensure access to and continuity of quality community-level Implanon care.
