Contraception prescribing in England during the COVID-19 pandemic

BACKGROUND

National lockdowns in England due to COVID-19 resulted in rapid shifts in healthcare provision, including in primary care where most contraceptive prescriptions are issued. This study aimed to investigate contraception prescribing trends in primary care during the pandemic and the impact of socioeconomic deprivation.

METHODS

Prescribing data were accessed from the English Prescribing Dataset for the first year of the COVID-19 pandemic (1 March 2020-28 February 2021) and the year prior (1 March 2019-29 February 2020). Data were analysed by geographical region (London, Midlands and East of England, North of England, South of England) and contraceptive type (progestogen-only pill (POP), combined oral contraception (COC), emergency hormonal contraception (EHC) and contraceptive injections). Differences in prescribing rates were calculated using Poisson regression. Pearson correlation coefficients were calculated for the Index of Multiple Deprivation (IMD) scores for each Clinical Commissioning Group (CCG) in the North East and North Cumbria (NENC).

RESULTS

Contraception prescribing rates decreased overall during the COVID-19 pandemic in England (Poisson regression coefficient (β)=-0.035), with a statistically significant (p<0.01) decrease in all four regions. Prescriptions decreased for COC (β=-0.978), contraceptive injections (β=-0.161) and EHC (β=-0.2005), while POP (β=0.050) prescribing rates increased. There was a weak positive correlation between IMD and prescribing rates in NENC (p>0.05).

CONCLUSIONS

Contraception provision was impacted by COVID-19 with an overall decrease in prescribing rates. The deprivation results suggest that this may not be a significant contributing factor to this decrease. Further research is recommended to better understand these changes, and to ensure that services respond appropriately to population needs.

Factors affecting female sexual well-being: a 5-year follow-up of a randomised clinical trial on post-abortion contraception

INTRODUCTION

Sexual well-being is associated with general well-being. Several factors, such as overweight, infertility, anxiety and sex hormones, also play a role, but the effects of hormonal contraception remain a point of debate. We characterised the factors associated with sexual well-being in fertile-aged women following induced abortion.

METHODS

A 5-year follow-up of a nested, longitudinal, cohort study examining the effects of routine provision of intrauterine contraception as part of abortion care. Sexual well-being, anxiety and quality of life were assessed annually using validated questionnaires (McCoy Female Sexuality Questionnaire, State-Trait Anxiety Inventory and EuroQoL), along with data on general and reproductive health, and relationship status. Of the 742 women participating in the trial, 290 (39%) provided sufficient follow-up data and were included in this study.

RESULTS

Based on trajectories of McCoy scores across the 5-year follow-up, two groups were identified: those with stable and higher (n=223, 76.9%) and those with declining sexual well-being (n=67, 23.1%). Women in the group of declining sexual well-being had significantly higher levels of anxiety and lower quality of life at all time points. They also had chronic diseases more often and were less happy in their relationships. No differences were found in method of contraception when classified as hormonal versus non-hormonal, or long-acting versus short-acting reversible contraception.

CONCLUSIONS

Lower anxiety and higher quality of life are associated with stable and higher sexual well-being. Method of contraception or relationship status are not associated with sexual well-being during long-term follow-up in fertile-aged women.

Is There a Special Role for Ovarian Hormones in the Pathogenesis of Lobular Carcinoma?

Lobular carcinoma represent the most common special histological subtype of breast cancer, with the majority classed as hormone receptor positive. Rates of invasive lobular carcinoma in postmenopausal women have been seen to increase globally, while other hormone receptor-positive breast cancers proportionally have not followed the same trend. This has been linked to exposure to exogenous ovarian hormones such as hormone replacement therapy. Reproductive factors resulting in increased lifetime exposure to endogenous ovarian hormones have also been linked to an increased risk of lobular breast cancer, and taken together, these data make a case for the role of ovarian hormones in the genesis and progression of the disease. In this review, we summarize current understanding of the epidemiological associations between ovarian hormones and lobular breast cancer and highlight mechanistic links that may underpin the etiology and biology.

Women at Altitude: Menstrual-Cycle Phase, Menopause, and Exogenous Progesterone Are Not Associated with Acute Mountain Sickness

Gardner, Laurel, Linda E. Keyes, Caleb Phillips, Elan Small, Tejaswi Adhikari, Nathan Barott, Ken Zafren, Rony Maharjan, and James Marvel. Women at altitude: Menstrual-cycle phase, menopause, and exogenous progesterone are not associated with acute mountain sickness. High Alt Med Biol. 00:000-000, 2024. Background: Elevated progesterone levels in women may protect against acute mountain sickness (AMS). The impact of hormonal contraception (HC) on AMS is unknown. We examined the effect of natural and exogenous progesterone on the occurrence of AMS. Methods: We conducted a prospective observational convenience study of female trekkers in Lobuche (4,940 m) and Manang (3,519 m). We collected data on last menstrual period, use of exogenous hormones, and development of AMS. Results: There were 1,161 trekkers who met inclusion criteria, of whom 307 (26%) had AMS. There was no significant difference in occurrence of AMS between women in the follicular (28%) and the luteal (25%) phases of menstruation (p = 0.48). The proportion of premenopausal (25%) versus postmenopausal women (30%) with AMS did not differ (p = 0.33). The use of HC did not influence the occurrence of AMS (HC 23% vs. no HC 26%, p = 0.47), nor did hormonal replacement therapy (HRT) (HRT 11% vs. no HRT 31%, p = 0.13). Conclusion: We found no relationship between menstrual-cycle phase, menopausal status, or use of exogenous progesterone and the occurrence of AMS in trekkers and conclude that hormonal status is not a risk factor for AMS. Furthermore, women should not be excluded from future AMS studies based on hormonal status.

Endometriosis risk and hormonal contraceptive usage: A nationwide cohort study

OBJECTIVE

To investigate whether an early need of hormonal contraceptive (HC), or a failure to find a suitable method, are warning signs for endometriosis.

DESIGN

A retrospective cohort study.

SETTING

Sweden.

POPULATION

The cohort consisted of 720 805 women aged 12-27 years during the period 2005-2017. All women, regardless of whether they received a diagnosis of endometriosis or not (reference group), were included.

METHODS

We used data from Swedish national registers. Risks are expressed as crude and adjusted hazard ratios (HRs and aHRs, respectively) with 95% confidence intervals (95% CIs), adjusted for age, education level, civil status, parity, country of birth, and diagnoses of infertility, dysmenorrhea or depression.

MAIN OUTCOME MEASURES

A diagnosis of endometriosis between 12 and 27 years of age.

RESULTS

During this period, 3268 women were diagnosed with endometriosis (0.45%). Women who started HC at the ages of 12-14 years had a higher risk of receiving the diagnosis (aHR 2.53, 95% CI 2.21-2.90) than those who began at age 17 years or older. Having tried more types of HCs was associated with a twofold increased risk of endometriosis (more that three types of HC, aHR 2.31, 95% CI 1.71-3.12). Using HC for more than 1 year was associated with a decreased risk of endometriosis (>1 year, aHR 0.53, 95% CI 0.48-0.59). Women with endometriosis more commonly had dysmenorrhea, depression or infertility.

CONCLUSIONS

The use of HCs at an early age and a failure to find a suitable HC were identified as warning signs of later receiving an endometriosis diagnosis. A longer duration of HC usage reduced the risk of receiving the diagnosis.

Implementation and Perception of Outpatient Pharmacists Prescribing Hormonal Contraceptives in North Carolina

BACKGROUND

North Carolina (NC) House Bill 96, effective February 2022, enabled trained immunizing pharmacists across the state to prescribe hormonal contraceptives (HCs). However, the extent and barriers to deployment are unknown. The purpose of this study was to describe the uptake and challenges from outpatient pharmacists who trained to provide HCs in an outpatient practice to assist others in the implementation of this service.

OBJECTIVES

The primary objective was to estimate the proportion of trained NC pharmacists who provided HCs in an outpatient setting. The secondary objective was to identify barriers during the implementation of this service.

METHODS

This cross-sectional, anonymous, web-based survey was emailed on December 13, 2022 to NC-licensed pharmacists enrolled in the required training. A reminder email was sent on January 10, 2023, with all responses considered up to January 31, 2023. Pharmacists licensed in NC who performed at least 50% of their clinical practice in an outpatient setting were included. The primary endpoint was having prescribed HC (Y/N). All endpoints were analyzed using descriptive statistics.

RESULTS

Of 1,633 pharmacists eligible, 96 completed responses were included in the analysis (5.9%). Training was incomplete in 11/96 (11.5%), and 66/96 (68.8%) completed the training without implementing the service. Of the remaining 19/96 (19.8%) that developed a HC service, 15/96 (15.6%) had prescribed HCs. Among the 15 prescribing pharmacists, all reported positive patient feedback, while 7/15 reported improved job satisfaction. Among all 96 respondents, barriers reported included time constraints (49%) and a lack of appropriate reimbursement (43.8%).

CONCLUSION

Few HC-trained NC outpatient pharmacists are prescribing HCs. Addressing prescribing barriers would potentially expand the scope of this service and further innovate the outpatient pharmacy setting.

Impact of pre-treatment in GnRH-antagonist cycles triggered with GnRH agonist on reproductive outcomes

OBJECTIVE

Pre-treatment (PT) therapies in IVF are known to be used as pre-stimulation modality to improve cycle outcomes. This study aims to assess whether PT in GnRH antagonist cycles triggered with GnRH-agonist impact oocyte maturation response.

METHODS

Data were retrospectively collected for patients who underwent GnRH antagonist cycle with agonist triggering with and without PT. The patients were allocated to groups according to their PT status. The primary outcome evaluated was suboptimal maturation response. Suboptimal maturation to trigger was defined as no oocyte upon retrieval when adequate response was expected.

RESULTS

The study population included 196 patients who underwent GnRH antagonist cycle with agonist triggering. The study group included 69 patients who received PT. The control group included 127 patients with no PT. In univariate analysis, the PT group significantly displayed suboptimal response compared to the controls (p = 0.008). All the patients in the study group with suboptimal response (with or without hCG re-triggering) were treated with GnRH-agonist as PT. Basal and pre-trigger LH values were significantly lower in the study group compared to controls (p < 0.001). Multivariate regression analysis revealed that PT with GnRH agonist was a significant predictor for suboptimal response.

CONCLUSIONS

Pre-treatment, and particularly the use of GnRH-agonist as PT in antagonist cycles triggered with agonist, increases the risk of suboptimal response to GnRH-agonist trigger. This might be explained by prolonged pituitary suppression, which lasts beyond the PT cessation.

Endovascular Thrombectomy and Lysis for Acute Renal Vein Thrombosis: Indications, Technical Aspects, Outcome, and Disease Etiology

PURPOSE

To report a rare case of acute renal vein thrombosis (RVT) that was treated with endovascular thrombectomy and lysis, and discuss potential etiology and indications for catheter-directed management.

CASE REPORT

A 21-year-old female athlete presented with sudden pain in her left flank and vomiting. A 3-phase computed tomography (CT) angiogram identified total occlusion of the left renal vein with no excretion from the swollen tender left kidney. Catheter-directed thrombolysis and thrombectomy were initiated 24 hours after onset of symptoms. Complete resolution of the RVT with normalized renal function was achieved. Post-operative Doppler ultrasound scan confirmed normal renal resistance and flow in the renal vein. The patient was discharged on Apixaban and remains well at 6 months. Combined hormonal contraception via an intra-vaginal ring and raised Factor VIII activity were the only identified risk factors.

CONCLUSION

Acute complete RVT with impaired kidney function is rare. Combined hormonal contraception and increased Factor VIII activity were potential risk factors. Endovascular thrombectomy and lysis restored renal perfusion and function, and can be used effectively in the management of fit patients with acutely compromised kidney function from total renal vein obstruction.

Comparison of Combined Parenteral and Oral Hormonal Contraceptives: A Systematic Review and Meta-Analysis of Randomized Trials

BACKGROUND

Delivering contraceptive hormones through a transdermal patch or a vaginal ring might have advantages over the traditional oral route.

OBJECTIVES

To compare the effectiveness, compliance, and side effect profile of oral and parenteral drug administration methods.

METHODS

We performed a systematic literature search in four medical databases-MEDLINE (via PubMed), Cochrane Library (CENTRAL), Embase, and Scopus-from inception to 20 November 2022. Randomized controlled trials assessing the efficacy, compliance, and adverse event profile of combined parenteral and oral hormonal contraceptives were included.

RESULTS

Our systematic search provided 3952 records; after duplicate removal, we screened 2707 duplicate-free records. A total of 13 eligible studies were identified after title, abstract, and full-text selection. We observed no significant difference in contraceptive efficacy (Pearl Index) between oral and parenteral drug administration (MD = -0.06, CI: -0.66-0.53; I2 = 0%). We found significant subgroup differences between parenteral methods in terms of compliance (χ2 = 4.32, p =0.038, I2 = 80%) and certain adverse events: breast discomfort (χ2 = 19.04, p =0.001, I2 = 80%), nausea (χ2 = 8.04, p =0.005, I2 = 75%), and vomiting (χ2 = 9.30, p =0.002; I2 = 72%).

CONCLUSION

Both parenteral and oral contraceptives can be used as an effective contraceptive method, and the route of administration should be tailored to patient needs and adverse event occurrence.

Reproductive healthcare in adolescents with autism and other developmental disabilities

BACKGROUND

Adults with developmental disabilities often have less access to reproductive health services than adults without these disabilities. However, little is known about how adolescents with developmental disabilities, including autism, access reproductive healthcare.

OBJECTIVE

We aimed to characterize the use of reproductive healthcare services among adolescents with autism and those with other developmental disabilities in comparison with adolescents with typical development, to be consistent with person-first language.

STUDY DESIGN

We conducted a cohort study of a sample of adolescents who were continuously enrolled members of Kaiser Permanente Northern California, an integrated healthcare system, from ages 14 to 18 years. The final analytical sample included 700 adolescents with autism, 836 adolescents with other developmental disabilities, and 2187 typically developing adolescents who sought care between 2000 and 2017. Using the electronic health record, we obtained information on menstrual conditions, the use of obstetrical-gynecologic care, and prescriptions of hormonal contraception. We compared healthcare use between the groups using chi-square tests and covariate-adjusted risk ratios estimated using modified Poisson regression.

RESULTS

Adolescents with autism and those with other developmental disabilities were significantly more likely to have diagnoses of menstrual disorders, polycystic ovary syndrome, and premenstrual syndrome than typically developing adolescents. These 2 groups also were less likely than typically developing peers to visit the obstetrician-gynecologist or to use any form of hormonal contraception, including oral contraception, hormonal implants, and intrauterine devices. Adolescents in all 3 groups accessed hormonal contraception most frequently through their primary care provider, followed by an obstetrician-gynecologist.

CONCLUSION

Adolescents with autism and those with other developmental disabilities are less likely than their typically developing peers to visit the obstetrician-gynecologist and to use hormonal contraception, suggesting possible care disparities that may persist into adulthood. Efforts to improve access to reproductive healthcare in these populations should target care delivered in both the pediatric and obstetrics-gynecology settings.

Associations of reproductive factors and exogenous estrogens with global and domain-specific cognition in later life

INTRODUCTION

Few studies have comprehensively examined the impact of reproductive factors (i.e., reproductive window, parity, hormonal contraception [HC], and menopausal hormone therapy [MHT]) on global and domain-specific cognition in later life.

METHODS

We studied a population-based sample of 2458 women (median age 74.2 years) residing in Olmsted County, Minnesota; participants underwent a clinical evaluation and comprehensive cognitive testing.

RESULTS

The length of a woman's reproductive window was not associated with cognition. Higher parity was associated with greater cognitive decline in all domains. Ever HC use was associated with less decline in all domains. Ever MHT use was associated with greater decline in global cognition and all domain-specific z-scores except visuospatial; results were driven by women who initiated MHT 5 or more years after menopause. Additional adjustments for APOE and vascular-related covariates did not attenuate the results.

DISCUSSION

Multiple reproductive risk factors are associated with cognitive decline in later life.

HIGHLIGHTS

The length of a woman's reproductive window was not associated with cognition longitudinally. Greater parity was associated with greater cognitive decline longitudinally. Ever HC use was associated with less decline in global cognition and all domain-specific z-scores longitudinally (all p < 0.01). Ever MHT use was associated with greater decline in global cognition and all domain-specific z-scores except visuospatial longitudinally (all p < 0.01). The greatest cognitive decline was among women who initiated MHT more than 5 years after menopause.

Hormonal Contraceptive Use Is Associated With a Decreased Incidence of Hypothyroidism

OBJECTIVE

Hypothyroidism is one of the most common endocrine disorders affecting 5 to 10 times more women than men. Given this higher incidence in women, it is possible that hormonal differences or medications more commonly used by women may play a role in the risk of developing hypothyroidism. We hypothesized that hormonal contraception affects the risk of developing hypothyroidism.

METHODS

Using the TriNetX database, we developed a case-control study and identified women aged 18 to 45 years in 4 distinct groups: (1) estrogen-progestin contraceptive (EPC) use, (2) progestin-only contraceptive (POC) use, (3) progestin-containing intrauterine device (IUD) use, and (4) controls. For each group, we ascertained data including the diagnosis of hypothyroidism, alcohol use, tobacco use, and body mass index.

RESULTS

We identified 18 578 patients with sufficient data: EPC use, n = 5849; POC use, n = 5052; IUD use, n = 1000; and controls, n = 6677. A total of 118 individuals (1.8%) in the control group and 165 individuals (1.4%) who received hormonal contraception developed hypothyroidism. After using a logistic model to account for cofounding variables, all forms of hormonal contraception (EPC, POC, and IUD) had a protective effect against the diagnosis of hypothyroidism. POC and IUD uses had the greatest protective effect, with odds ratios of 0.14 and 0.12, respectively. EPC had a less pronounced but still significant effect, with an odds ratio of 0.30 (P < .001).

CONCLUSION

This study of >18 000 women and the risk of developing hypothyroidism demonstrates a protective effect of hormonal contraceptive use. Our data, both unadjusted and adjusted using a logistic model to account for cofounding variables, suggest that the use of hormonal contraception, in any form, decreases the risk of developing hypothyroidism.

Hormonal contraception and risk for cognitive impairment or Alzheimer's disease and related dementias in young women: a scoping review of the evidence

Introduction

Women are significantly more likely to develop Alzheimer's disease and related dementias (ADRD) than men. Suggestions to explain the sex differences in dementia incidence have included the influence of sex hormones with little attention paid to date as to the effect of hormonal contraception on brain health. The aim of this scoping review is to evaluate the current evidence base for associations between hormonal contraceptive use by women and non-binary people in early adulthood and brain health outcomes.

Methods

A literature search was conducted using EMBASE, Medline and Google Scholar, using the keywords "hormonal contraception" OR "contraception" OR "contraceptive" AND "Alzheimer*" OR "Brain Health" OR "Dementia".

Results

Eleven papers were identified for inclusion in the narrative synthesis. Studies recruited participants from the UK, USA, China, South Korea and Indonesia. Studies included data from women who were post-menopausal with retrospective data collection, with only one study contemporaneously collecting data from participants during the period of hormonal contraceptive use. Studies reported associations between hormonal contraceptive use and a lower risk of ADRD, particularly Alzheimer's disease (AD), better cognition and larger grey matter volume. Some studies reported stronger associations with longer duration of hormonal contraceptive use, however, results were inconsistent. Four studies reported no significant associations between hormonal contraceptive use and measures of brain health, including brain age on MRI scans and risk of AD diagnosis.

Discussion

Further research is needed on young adults taking hormonal contraceptives, on different types of hormonal contraceptives (other than oral) and to explore intersections between sex, gender, race and ethnicity.

Contraceptive effects on the cervicovaginal microbiome: Recent evidence including randomized trials

BACKGROUND

Until recently, most data regarding the effects of non-barrier contraceptives on the mucosal microbiome have derived from observational studies, which are potentially biased due to behavioral confounders that may mask their true biological effects.

METHOD OF STUDY

This narrative review summarises recent evidence of the effect of contraceptives on the cervicovaginal microbiome, emphasising data obtained through randomized trials.

RESULTS

Good quality data describe that initiation of long-acting progestin-only contraceptives, including levonorgestrel (LNG)-implant and the injectables depot-medroxyprogesterone acetate (DMPA-IM) and norethisterone enanthate (NET-EN) do not alter the mucosal microbial environment. Likewise, no strong evidence exists that the use of oral contraceptive pills (OCPs) is associated with alterations of the vaginal microbiome or increased risk of bacterial sexually transmitted infections (STIs). Limited data on the effect of intravaginal rings (IVRs) on the mucosal environment exist and show conflicting effects on the vaginal microbiota. Copper intrauterine device (Cu-IUD) initiation has been associated with bacterial vaginosis (BV) acquisition, including in a randomized trial. LNG-IUDs may have similar affects but need to be evaluated further.

CONCLUSION

Different synthetic hormones have divergent effects on the microbiome and therefore novel hormonal methods need to be rigorously evaluated. Furthermore, the addition of antiretrovirals into multipurpose technologies may alter the effects of the hormonal component. There is thus a critical need to improve our understanding of the biological effects of contraceptive hormones and delivery methods with different pharmacokinetic and chemical properties on the mucosal microbiome in rigorous trials, to inform the development of novel contraceptives and improve individual family planning guidance.

Salivary microbiome of healthy women of reproductive age

IMPORTANCE

The salivary microbiome has been proven to play a crucial role in local and systemic diseases. Moreover, the effects of biological and lifestyle factors such as oral hygiene and smoking on this microbial community have already been explored. However, what was not yet well understood was the natural variation of the saliva microbiome in healthy women and how this is associated with specific use of hormonal contraception and with the number of different sexual partners with whom microbiome exchange is expected regularly. In this paper, we characterized the salivary microbiome of 255 healthy women of reproductive age using an in-depth questionnaire and self-sampling kits. Using the large metadata set, we were able to investigate the associations of several host-related and lifestyle variables with the salivary microbiome profiles. Our study shows a high preservation between individuals.

Impact of estrogens on resting energy expenditure: A systematic review

The fear of weight gain is one of the main reasons for women not to initiate or to early discontinue hormonal contraception or menopausal hormone therapy. Resting energy expenditure is by far the largest component and the most important determinant of total energy expenditure. Given that low resting energy expenditure is a confirmed predictive factor for weight gain and consecutively for the development of obesity, research into the influence of sex steroids on resting energy expenditure is a particularly exciting area. The objective of this systematic review was to evaluate the effects of medication with natural and synthetic estrogens on resting energy expenditure in healthy normal weight and overweight women. Through complex systematic literature searches, a total of 10 studies were identified that investigated the effects of medication with estrogens on resting energy expenditure. Our results demonstrate that estrogen administration increases resting energy expenditure by up to +208 kcal per day in the context of contraception and by up to +222 kcal per day in the context of menopausal hormone therapy, suggesting a preventive effect of circulating estrogen levels and estrogen administration on weight gain and obesity development.

Risk of thromboembolism in patients with COVID-19 who are using hormonal contraception: a Cochrane systematic review

BACKGROUND

The coronavirus disease COVID-19 is associated with an increased risk of thrombotic events. Individuals with COVID-19 using hormonal contraception could be at additional risk for thromboembolism, but evidence is sparse.

METHODS

We conducted a systematic review on the risk of thromboembolism with hormonal contraception use in women aged 15-51 years with COVID-19. We searched multiple databases through March 2022, including all studies comparing outcomes of patients with COVID-19 using or not using hormonal contraception. We applied standard risk of bias tools to evaluate studies and GRADE methodology to assess certainty of evidence. Our primary outcomes were venous and arterial thromboembolism. Secondary outcomes included hospitalisation, acute respiratory distress syndrome, intubation, and mortality.

RESULTS

Of 2119 studies screened, three comparative non-randomised studies of interventions (NRSIs) and two case series met the inclusion criteria. All studies had serious to critical risk of bias and low study quality. Overall, there may be little to no effect of combined hormonal contraception (CHC) use on odds of mortality for COVID-19-positive patients (OR 1.0, 95% CI 0.41 to 2.4). The odds of hospitalisation for COVID-19-positive CHC users may be slightly decreased compared with non-users for patients with body mass index <35 kg/m2 (OR 0.79, 95% CI 0.64 to 0.97). Use of any type of hormonal contraception may have little to no effect on hospitalisation rates for COVID-19-positive individuals (OR 0.99, 95% CI 0.68 to 1.44).

CONCLUSIONS

Not enough evidence exists to draw conclusions regarding risk of thromboembolism in patients with COVID-19 using hormonal contraception. Evidence suggests there may be little to no or slightly decreased odds of hospitalisation, and little to no effect on odds of mortality for hormonal contraception users versus non-users with COVID-19.

Striatal dopamine synthesis and cognitive flexibility differ between hormonal contraceptive users and nonusers

In rodents and nonhuman primates, sex hormones are powerful modulators of dopamine (DA) neurotransmission. Yet less is known about hormonal regulation of the DA system in the human brain. Using positron emission tomography (PET), we address this gap by comparing hormonal contraceptive users and nonusers across multiple aspects of DA function: DA synthesis capacity via the PET radioligand 6-[18F]fluoro-m-tyrosine ([18F]FMT), baseline D2/3 receptor binding potential using [11C]raclopride, and DA release using methylphenidate-paired [11C]raclopride. Participants consisted of 36 healthy women (n = 15 hormonal contraceptive users; n = 21 naturally cycling/non users of hormonal contraception), and men (n = 20) as a comparison group. A behavioral index of cognitive flexibility was assessed prior to PET imaging. Hormonal contraceptive users exhibited greater DA synthesis capacity than NC participants, particularly in dorsal caudate, and greater cognitive flexibility. Furthermore, across individuals, the magnitude of striatal DA synthesis capacity was associated with cognitive flexibility. No group differences were observed in D2/3 receptor binding or DA release. Analyses by sex alone may obscure underlying differences in DA synthesis tied to women's hormone status. Hormonal contraception (in the form of pill, shot, implant, ring, or intrauterine device) is used by ~400 million women worldwide, yet few studies have examined whether chronic hormonal manipulations impact basic properties of the DA system. Findings from this study begin to address this critical gap in women's health.

In Utero Exposure to Hormonal Contraception and Mortality in Offspring with and without Cancer: A Nationwide Cohort Study

Approximately 400 million women of reproductive age use hormonal contraceptives worldwide. Eventually, pregnancy sometimes occurs due to irregular use. Use in early pregnancy is found to be associated with child morbidities including cancer, the main reason for disease-related death in children. Here, we add the missing piece about in utero exposure to hormonal contraception and mortality in offspring, including assessments of prognosis in children with cancer. In utero exposure to hormonal contraception may be associated with death since we found a hazard ratio (HR) of 1.22 (95% confidence interval (CI) 1.01-1.48) compared to children of mothers with previous use. The HRs were 1.22 (95% CI 0.99-1.13) for oral combined products and 2.92 (95% CI 1.21-7.04) for non-oral progestin-only products. A poorer prognosis was also found in exposed children with leukemia (3.62 (95% CI: 1.33-9.87)). If causal, hormonal contraception in pregnancy seems detrimental for offspring health and a marker of poorer prognosis in children with leukemia.

The effects of hormonal contraceptive use on sleep in women: A systematic review and meta-analysis

Hormonal contraceptives are some of the most widely used medications worldwide, but studies on their effects on sleep are contradictory, with some reporting a sleep-promoting effect, while others a sleep-inhibiting effect. Our objective was, therefore, to undertake a systematic review and meta-analysis of the literature on this subject to try to clarify their effects. A search was conducted in three databases (PubMed, Scopus and Web of Science). Only studies evaluating hormonal contraception use were considered eligible, and both objective and subjective sleep-related outcomes were considered. Individual effect size was calculated for each article, and meta-analyses were performed using a DerSimonian and Laird random effects method. The initial search identified 2076 articles, of which 13 met the criteria for the study after full text evaluation. A total of 33 meta-analyses were performed, three of them related to subjective measures and 30 considering data from polysomnography. The only statistically significant result between contraceptive users and non-contraceptive users was observed in respect of wake after sleep onset, which was 7 min shorter among contraceptive users (-7.12 [-12.80; -1.44]; I²  = 65%; p = 0.01). In conclusion, hormonal contraceptives are not associated with clinically relevant changes in sleep patterns in women.

Migraine with and without aura in relation to the menstrual cycle and other hormonal milestones: A prospective cohort study

BACKGROUND

Previous studies showed that the perimenstrual window is associated with an increased susceptibility to migraine attacks without aura, but had conflicting results regarding attacks with aura.

METHODS

We performed a longitudinal E-diary study among 526 premenopausal women with migraine. Differences in occurrence of perimenstrual migraine attacks between women with migraine with aura and without aura were assessed using a mixed effects logistic regression model. Additionally, participants completed a questionnaire about the influence of hormonal milestones on migraine frequency.

RESULTS

Prevalence of menstrual migraine did not differ between women with migraine without aura and migraine with aura (59% versus 53%, p  =  0.176). The increased risk of migraine attacks without aura during the perimenstrual window was similar for women with migraine without aura (OR[95%CI]:1.53 [1.44-1.62]) and those with migraine with aura (1.53 [1.44-1.62]). The perimenstrual window was not associated with increased risk of migraine aura attacks (1.08 [0.93-1.26], p = 0.314). Women with migraine with aura more often reported increased migraine frequency during pregnancy and breastfeeding compared to women with migraine without aura, but not during hormonal contraception use.

CONCLUSION

Sex hormone levels seem to differently affect the trigeminovascular system (migraine headache) and the susceptibility to cortical spreading depolarization (aura). Exclusively migraine attacks without aura should be interpreted as perimenstrual attacks.

The Effect of Hormonal Contraception Use on Ovarian Reserve Markers and the Uptake of Assisted Reproductive Technology in Individuals Seeking an Infertility Evaluation

Background and objective The effects of hormonal contraception (HC) use on ovarian reserve (OR) markers in individuals seeking an infertility evaluation and the success of assisted reproductive technology (ART) warrant further investigation. Therefore, the aim of this study was to determine if women seeking an evaluation for unexplained infertility who used long-term (≥2 years) HC have lower ovarian reserve (OR) markers and higher uptake of ART compared to short-term (<2 years) or never HC users. Methods We performed a cross-sectional patient survey involving a retrospective medical chart review of patients seeking an evaluation for unexplained infertility at the University of Colorado Advanced Reproductive Medicine (CU ARM) clinic. Results Most participants (87%; 107/123) reported a history of HC use with 98 (79.7%) reporting long-term continuous use for two or more years. Median OR markers were similar between long-term and short-term/never HC users [anti-Müllerian hormone (AMH): 2.4 vs. 3.2, p=0.20; antral follicle count (AFC): 18 vs. 26, p=0.10; follicle-stimulating hormone (FSH): 7.6 vs. 6.3, p=0.26] and remained so after adjusting for age and diagnosis of polycystic ovarian syndrome (PCOS) or primary ovarian insufficiency (POI) in linear regression models. However, among HC users aged less than 30 years (n=9), those who had discontinued HC between two and three years prior to the assessment of their OR markers had a 6.20 ng/mL increase in AMH level compared to those who had discontinued HC less than two years prior to the assessment (p=0.02). Additionally, there was a marginally increased use of ART overall among long-term HC users compared to short-term/never HC users (64.3% vs. 44.0%, p=0.06), specifically in the use of in vitro fertilization (IVF) (58.7% vs. 18.2%, p=0.01). Among long-term HC users, ovulation induction was less likely to result in live birth compared to short-term/never HC users (8.9% vs. 62.5%, p<0.001); however, after adjusting for age, PCOS, POI, and type of ART used, there was no difference in the odds of live birth after ART between long-term HC users and short-term/never users. Conclusion While long-term HC users report increased use of ART, in particular IVF, the overall conception rates and live birth outcomes among ART users do not appear to be significantly affected by a history of long-term HC use.

"There Are Many of Us": Online Testimonies From "Pill Victims" as a New Form of Health Activism

The French pill scare is usually presented as a "media debate" triggered by the case of Marion Larat, a young woman who suffered a stroke attributed to the pill she was taking. This article intends to focus on a practice that preceded, accompanied, and followed this health scare: the publication of online testimonies of thrombotic reactions posted on the website of the French Association of Victims of Pulmonary Embolism and Stroke Associated with Hormonal Contraception (Avep). Through a discourse analysis, we intend to analyze these online public self-reports as an activist practice aimed at criticizing the dominant medical discourse on contraception. Four discursive frames emerged: unpreparedness of women and doctors, denial of blame and search for the cause, breaking the silence and building solidarity, and collective action. The first two frames concern the process women put in place to obtain the right to speak about and criticize a medical practice. The right to speak is achieved through a concise narrative style focusing on facts, bodily manifestations, and risk factors. The second pair refers to the formation of pill victims as subjects with an ambivalent status and ephemeral agency. The testimonies build what we call "lone solidarity", that is, the creation of a social bond and action around a common experience of witnessing medical injustice that develops without any exchange between members. This proves to be inclusive and viral, but at the same time fiercely anti-representational with respect to political struggles or social identification.

Risk of thromboembolism in patients with COVID-19 who are using hormonal contraception

BACKGROUND

The novel coronavirus disease (COVID-19) has led to significant mortality and morbidity, including a high incidence of related thrombotic events. There has been concern regarding hormonal contraception use during the COVID-19 pandemic, as this is an independent risk factor for thrombosis, particularly with estrogen-containing formulations. However, higher estrogen levels may be protective against severe COVID-19 disease. Evidence for risks of hormonal contraception use during the COVID-19 pandemic is sparse. We conducted a living systematic review that will be updated as new data emerge on the risk of thromboembolism with hormonal contraception use in patients with COVID-19.

OBJECTIVES

To determine if use of hormonal contraception increases risk of venous and arterial thromboembolism in women with COVID-19. To determine if use of hormonal contraception increases other markers of COVID-19 severity including hospitalization in the intensive care unit, acute respiratory distress syndrome, intubation, and mortality. A secondary objective is to maintain the currency of the evidence, using a living systematic review approach.

SEARCH METHODS

⁠⁠⁠⁠⁠⁠We searched CENTRAL, MEDLINE, Embase, CINAHL, Global Index Medicus, Global Health, and Scopus from inception on March 2023, and monitored the literature monthly. We updated the search strategies with new terms and added the database Global Index Medicus in lieu of LILACS.

SELECTION CRITERIA

We included all published and ongoing studies of patients with COVID-19 comparing outcomes of those on hormonal contraception versus those not on hormonal contraception. This included case series and non-randomized studies of interventions (NRSI).

DATA COLLECTION AND ANALYSIS

One review author extracted study data and this was checked by a second author. Two authors individually assessed risk of bias for the comparative studies using the ROBINS-I tool and a third helped reconcile differences. For the living systematic review, we will publish updates to our synthesis every six months. In the event that we identify a study with a more rigorous study design than the current included evidence prior to the planned six-month update, we will expedite the synthesis publication.

MAIN RESULTS

We included three comparative NRSIs with 314,704 participants total and two case series describing 13 patients. The three NRSIs had serious to critical risk of bias in several domains and low study quality. Only one NRSI ascertained current use of contraceptives based on patient report; the other two used diagnostic codes within medical records to assess hormonal contraception use, but did not confirm current use nor indication for use. None of the NRSIs included thromboembolism as an outcome. Studies were not similar enough in terms of their outcomes, interventions, and study populations to combine with meta-analyses. We therefore narratively synthesized all included studies. Based on results from one NRSI, there may be little to no effect of combined hormonal contraception use on odds of mortality for COVID-19 positive patients (OR 1.00, 95% CI 0.41 to 2.40; 1 study, 18,892 participants; very low-certainty evidence). Two NRSIs examined hospitalization rates for hormonal contraception users versus non-users. Based on results from one NRSI, the odds of hospitalization for COVID-19 positive combined hormonal contraception users may be slightly decreased compared with non-users for patients with BMI under 35 kg/m2 (OR 0.79, 95% CI 0.64 to 0.97; 1 study, 295,689 participants; very low-certainty evidence). According to results of the other NRSI assessing use of any type of hormonal contraception, there may be little to no effect on hospitalization rates for COVID-19 positive individuals (OR 0.99, 95% CI 0.68 to 1.44; 1 study, 123 participants; very low-certainty evidence). We included two case series because no comparative studies directly assessed thromboembolism as an outcome. In a case series of six pediatric COVID-19 positive patients with pulmonary embolism, one (older than 15 years of age) was using combined hormonal contraception. In a second case series of seven COVID-19 positive patients with cerebral venous thrombosis, one was using oral contraceptives. One comparative study and one case series reported on intubation rates, but the evidence for both is very uncertain. In the comparative study of 123 COVID-19 positive patients (N = 44 using hormonal contraception and N = 79 not using hormonal contraception), no patients in either group required intubation. In the case series of seven individuals with cerebral venous thromboembolism, one oral contraceptive user and one non-user required intubation.

AUTHORS' CONCLUSIONS

There are no comparative studies assessing risk of thromboembolism in COVID-19 patients who use hormonal contraception, which was the primary objective of this review. Very little evidence exists examining the risk of increased COVID-19 disease severity for combined hormonal contraception users compared to non-users of hormonal contraception, and the evidence that does exist is of very low certainty. The odds of hospitalization for COVID-19 positive users of combined hormonal contraceptives may be slightly decreased compared with those of hormonal contraceptive non-users, but the evidence is very uncertain as this is based on one study restricted to patients with BMI under 35 kg/m2. There may be little to no effect of combined hormonal contraception use on odds of intubation or mortality among COVID-19 positive patients, and little to no effect of using any type of hormonal contraception on odds of hospitalization and intubation for COVID-19 patients. We noted no large effect for risk of increased COVID-19 disease severity among hormonal contraception users. We specifically noted gaps in pertinent data collection regarding hormonal contraception use such as formulation, hormone doses, and duration or timing of contraceptive use. Differing estrogens may have different thrombogenic potential given differing potency, so it would be important to know if a formulation contained, for example, ethinyl estradiol versus estradiol valerate. Additionally, we downgraded several studies for risk of bias because information on the timing of contraceptive use relative to COVID-19 infection and method adherence were not ascertained. No studies reported indication for hormonal contraceptive use, which is important as individuals who use hormonal management for medical conditions like heavy menstrual bleeding might have different risk profiles compared to individuals using hormones for contraception. Future studies should focus on including pertinent confounders like age, obesity, history of prior venous thromboembolism, risk factors for venous thromboembolism, and recent pregnancy.

Medication Adherence and Contraceptive Counseling

Combined oral contraceptives (COC) are a very popular form of birth control. Incorrect use and lack of adherence to treatment reduce the effectiveness of this method. Having a standard tool to identify poor-adherence profiles quickly and objectively can be helpful for midwives and potentially for COC users. The MMAS-4 adherence scale has been used in various medical fields, but there is little evidence of its potential in contraceptive consultation. This paper presents a piece of multicenter observational research based on a sample of 327 women who had attended contraceptive counselling in Spain and were COC users or had informed the midwife that they want to start to use this method. Two interviews were conducted: at the time of consultation and after one year. In our research, the MMAS-4 identified high-risk behaviors: during the 1-year follow-up period, COC users classified as poorly adherent had a significantly higher risk of missed contraceptive pills, more incidents and problems related to the method of contraception, as well as a lower degree of satisfaction with the contraceptive method. One case of unplanned pregnancy and two cases of emergency contraception were identified, all of them corresponding to poorly adherent women. The use of MMAS-4 in consultation can improve midwives' contraceptive counselling.

Bleeding profile satisfaction and pain and ease of placement with levonorgestrel 19.5 mg IUD: findings from the Kyleena® Satisfaction study

PURPOSE

To investigate bleeding profile satisfaction and pain and ease of placement with levonorgestrel 19.5 mg IUD in routine clinical practice.

METHODS

Women who independently chose levonorgestrel 19.5 mg IUD during routine counselling were invited to participate in this prospective, multinational, observational study. Patient-reported pain and clinician-reported ease of placement were assessed. Bleeding profile satisfaction was evaluated at 12 months/premature end of observation.

RESULTS

Most participants (77.8%, n = 878/1129) rated levonorgestrel 19.5 mg IUD placement pain as 'none' or 'mild' and most clinicians (91.1%, n = 1029/1129) rated placement as 'easy'. Pain was more often rated higher in nulliparous compared with parous (p < .0001) and younger (<26 years) compared with older participants (p < .0001), although 67.7% and 69.0% of nulliparous and younger participants respectively reported 'none' or 'mild' pain. Bleeding profile satisfaction at 12 months/end of observation was similar in parous (72.9%, n = 318/436) and nulliparous (69.6%, n = 314/451) participants. Most participants irrespective of age reported bleeding profile satisfaction, ranging from 67.8% (n = 206/304) for 18-25 years to 76.5% (n = 218/285) for >35 years.

CONCLUSION

We observed high bleeding profile satisfaction regardless of age or parity with levonorgestrel 19.5 mg IUD and confirmed that device placement is easy and associated with no more than mild pain in most cases in routine clinical practice. Real-world evidence from the Kyleena^® Satisfaction Study in routine clinical practice shows high bleeding profile satisfaction with levonorgestrel 19.5 mg IUD regardless of age or parity. IUD placement was easy and associated with little to no pain for most women.

No decrease in perseverance and performance on cognitive tasks in Danish cohort of hormonal contraceptive users

Cognitive consequences of hormonal contraceptives (HCs) are largely underexplored, despite the popularity of use. This study investigates the association between perseverance during cognitively challenging tasks and the use of HCs among Danish women. We hypothesised that women using HCs show decreased perseverance across tasks compared to their naturally cycling counterparts. We further hypothesised that HC using women would show decreased performance as a measure of accuracy (i.e. more incorrect answers) compared to naturally cycling women. The study used a cross-sectional repeated measures design, consisting of a Danish version of the Anagram Persistence Task and the Hagen Matrices Test, followed by an extensive survey documenting menstrual and HC history for each participant. The study was conducted online. Data processing was conducted on data from 129 participants. The former hypothesis was analysed through multilevel regression with a nested random effects structure on log-transformed data. The latter hypothesis was analysed through a multilevel generalised linear model with a nested random effects structure using the binomial family. No support was found for either of the hypotheses.

Perception and use of reversible contraceptive methods in Germany: A social listening analysis

BACKGROUND

With an increasing array of contraceptives in the market, it is important to understand how users perceive them and how their interests evolve over time.

OBJECTIVES

In this analysis, we aimed to examine the contraceptive interests of women and couples in Germany using data derived from social media posts.

STUDY DESIGN

Social listening analysis.

METHODS

Posts from Urbia-a German Internet community-mentioning at least one reversible contraceptive method between April 2006 and April 2021 were carefully selected by searching for a defined set of keywords and phrases. The frequency of mention of each method was studied and their trend over the last 5 years was analyzed. The significance of trends was evaluated using Mann-Kendall test. Additionally, 656 random posts were individually assessed for method transitions and problems associated with specific contraceptives.

RESULTS

The contraceptive pill was the most frequently mentioned method of contraception followed by natural family planning methods, condom, hormonal coil, and copper/gold coil. Although general interest in hormonal contraception was higher compared to non-hormonal, interest in the pill decreased and interest in natural family planning and copper/gold coil increased. Most women switched from the pill to non-hormonal methods, almost half of them using a condom. Almost all migrations to natural family planning were from the pill and most migrations to non-hormonal intrauterine devices such as the coil were from hormonal methods. The common problem associated with most contraceptives was side effects.

CONCLUSION

Social media provides valuable information about contraceptive experiences that can be used to monitor contraceptive prevalence patterns and attitudes within a large population in a very short span of time. A good understanding of how various contraceptives are currently perceived helps in identifying strategies for improving existing family planning policies.

PLAIN LANGUAGE SUMMARY

Currently, there are a variety of contraceptive products available in the market. To understand how users perceive them and how their interest evolves over time, we analyzed social media posts from Urbia, a German Internet platform. We scraped posts between 2016 and 2021 from the "child-desire" and "contraception" forums and analyzed the relative frequency of mentions of different contraceptive methods. We also looked at 1000 individual posts from 1000 different users, analyzed method switches and the problems associated with individual methods of use. The oral pill was the most frequently mentioned method of contraception followed by natural family planning methods, condom, hormonal coil, and copper/gold coil. Over the last 5 years however, the mention of the pill dropped, whereas the mentions of natural family planning and copper or gold coil increased. Further analysis of individual posts showed most women migrating from the pill to other non-hormonal methods such as natural family planning and condom. Almost all migrations to natural family planning were from the pill and most migrations to non-hormonal intrauterine devices such as the coil were from hormonal methods. The most common problem associated with the pill and non-hormonal intrauterine devices was side effects. Through this analysis we show that social media serves as a useful tool to monitor contraceptive prevalence and attitudes within a large population in a very short span of time. Our findings give policy makers an idea on the topics where more counseling and education may be required to help women and couples find their best suited method of contraception.

User interest in a new non-hormonal long-acting reversible contraceptive: what impact does mechanism of action have on past and future contraceptive decision-making?

BACKGROUND

We are in the process of developing a new non-hormonal long-acting reversible method of contraception (LARC) in recognition of the fact that a significant minority of users are unhappy with their current method. Our method has a novel (post-fertilisation) mechanism of action (MOA), but little is known about the value users place on this.

METHODS

Using in-depth interviews, we explored 30 Australian end-users' experiences of contraception, recruited via social media. A thematic approach was taken to examine the influence the MOA has on choice and factors affecting willingness to try current methods and a novel non-hormonal LARC with a post-fertilisation effect.

RESULTS

We identified two themes that were the most salient across all interviews: that contraceptive decision-making involves a trade-off of priorities, influenced by contraceptive properties (including MOA) and the context in which contraception is used; and views on novel methods of contraception were influenced by willingness to trial new products and interest in non-hormonal options. Side effects, efficacy, and the financial burden of contraceptives were all considered more important than MOA during decision-making. Participants were willing to try a new method if endorsed by trusted sources, including friends and medical practitioners, and were enthusiastic to try a novel LARC with no hormones.

CONCLUSION

This study found that the MOA had minimal impact on participants' choice of contraception. Rather, avoidance of hormones and side effects influenced willingness to try a novel method over any unacceptable aspects of a post-fertilisation MOA.

Experiences using a progestin-only pill in an over-the-counter environment in the United States: a cross-sectional survey

BACKGROUND

Efforts are underway to make a progestin-only pill (POP) over the counter (OTC) in the United States (US); however, little is known about POP user experiences, which could impact uptake and continuation.

METHODS

From January 2020-September 2021, we conducted a cross-sectional online survey with individuals who used OTC POPs in a US trial. We calculated descriptive statistics and Pearson chi-square and Fisher's exact tests to assess menstrual bleeding acceptability, how OTC POP experiences compared with prior contraceptive methods, and preferred ways to get answers to questions during OTC POP use.

RESULTS

Among 550 adult and 115 adolescent participants, 80% (n=531) felt their menstrual bleeding was acceptable. Participants reported a range of menstrual bleeding experiences compared with prior long-acting or hormonal methods used; 58% (n=84) said the POP bleeding was similar or better and 36% (n=53) said it was worse. Among participants who used contraception in the month prior to the trial, 77% (n=201) said their overall OTC POP experience was similar or better. Top benefits compared with prior methods included less worry about pregnancy, ease of access, fewer side effects, and greater decision-making power. Adults preferred to get answers about OTC POPs via webpage or app, whereas teens preferred asking pharmacists or other healthcare providers.

CONCLUSIONS

Overall, OTC POP users in a trial setting found the menstrual bleeding acceptable and the method similar to or better than previous methods. POP labelling should provide clear messaging about bleeding changes users may experience.

The progestin-only pills drospirenone 4 mg and desogestrel 0.075 mg as an option for the management of dysmenorrhea and mastodynia

INTRODUCTION

Dysmenorrhea and mastodynia are the most common gynecologic pain causes in women of all ages and races during their reproductive life. The following study aimed to show the influence of two POP´s in the development of dysmenorrhea and mastodynia after nine months of use.

MATERIAL AND METHODS

A total of 858 women with 6691 drospirenone (DRSP) cycles and 332 women with 2487 desogestrel (DSG) cycles were analyzed. Women included in this study were all child-bearing potentials, at risk of pregnancy, agreeing to use only the study medication for contraception for the duration of the study medication treatment, aged 18 to 45.

RESULTS

At screening, 168 (19.6%) of the 858 patients using DRSP and 64 (19,3%) of the DSG patients reported that they had suffered from dysmenorrhea within six cycles prior to the first visit before starting with the medication. 20,2% of the DRSP and 10,9% of the DSG group had a sever dysmenorrhea. After 9 cycles this was reduced to 0,6% and 3,1% respectively. In total, 96 women (11.2%) in the DRSP and 49 (14,8%) experienced mastodynia within six cycles before the screening. Of these 91.6% in the DRSP group and 91,8% in the DSG group had no or mild mastodynoa at follow-up.

DISCUSSION

The progestins 4 mg and desogestrel 0,075 mg showed a marked effect in the non-contraceptive aspects of dysmenorrhea and mastodynia so that new possibilities are opened for these two benign gynecological diseases. Future studies must reaffirm these first data.

Hands-On Training in a Digital World: A Novel Simulation-Based Virtual Training Program for Placement and Removal of the Subdermal Contraceptive Implant

OBJECTIVE

The COVID-19 pandemic necessitated a shift from traditional in-person instruction for learning new technical skills to virtual delivery of medical education training. The objectives of this study were to develop and evaluate a virtual simulation-based training program for Canadian health care professionals (HCPs) on the insertion, localization, and removal of the etonogestrel subdermal contraceptive implant.

METHODS

A scientific committee of Canadian family planning experts developed a 2-part virtual training program during the COVID-19 pandemic. Core educational content (part 1) was provided in an asynchronous, self-directed, online format. Part 2 consisted of synchronous, simulation-based training using web conferencing. The HCPs were provided with model arms and placebo applicators; the trainers demonstrated implant insertion and removal techniques, and trainees received individual feedback. All trainees were asked to complete an online evaluation upon completion of the program.

RESULTS

Between September 22, 2020, and December 31, 2021, 83 trainers conducted 565 virtual training sessions. A total of 3162 HCPs completed part 1 of the training program, of whom 2740 had completed part 2 by December 31, 2021. Participants reported high levels of satisfaction with virtual simulation-based training; 96.5% of respondents (1570/1627) agreed that the virtual format was effective. Additional training prior to inserting the implant in clinical practice was requested by 4.5% of respondents (75/1671).

CONCLUSION

Virtual simulation-based learning provides effective education and technique training for etonogestrel implant insertion and removal. Online training for implant use can be scaled, as needed, to reach professionals in remote or underserved locations. This virtual training approach may be appropriate for other technical or minor surgical procedures.

Birth Control Use and Access Including Pharmacist-Prescribed Contraception Services during COVID-19

The COVID-19 pandemic influenced health care with effects on contraception access emerging. The study objectives were to analyze pandemic impacts on birth control (BC) use and access; and evaluate perceptions of pharmacist-prescribed BC. A 50-item survey was distributed by 31 Michigan community pharmacies to women aged 18-45 over a three-month period. The survey link was also posted on two websites. 147 surveys were analyzed. Respondents were 29 ± 7.9 years old, primarily white (77%) and straight (81%). Fifty-eight percent of respondents used prescription BC, mostly to prevent pregnancy (84%) with oral pills (76%) being the most common formulation. Some BC users (25%) were worried about BC access and 27% had difficulty taking BC regularly. Half of the respondents (50%) would likely use pharmacist-prescribed BC if available, with advantages being more convenient than visiting a doctor's office (71%) and easier access (69%). The major concern about pharmacist-prescribed BC was women not receiving PAP smears and screenings (61%). Respondents reported high confidence (72%) in pharmacist-prescribed BC and believe it would help prevent unintended pregnancies (69%). Some respondents experienced altered BC use and access. Half of the respondents supported pharmacist-prescribed BC. Pharmacist-prescribed BC could help solve pandemic-related access problems.

Exogenous hormone use and the risk of surgically treated cataract: Evidence from 91 760 female participants in the 45 and Up Study

PURPOSE

To investigate the association between exogenous hormone use and the risk of cataract surgery among working-aged Australian women.

METHODS

A total of 91 760 female participants aged 45-65 years and without prior history of cataract surgery were prospectively enrolled between January 2006 and December 2009 in New South Wales (NSW), Australia. A baseline self-reported questionnaire was used to collect information on participant demographic, socio-economic, lifestyle characteristics, medical history as well as the use of hormonal contraception and hormone replacement therapy (HRT). Cataract surgery for these participants during 2006-2019 was determined according to the Medicare Benefits Schedule database. Cox regression was used to assess the association between exogenous hormone use and incident cataract surgery during the follow-up.

RESULTS

During a mean follow-up of 11.3 years, 10 444 participants underwent cataract surgery with a corresponding incidence of 11.4% (10 444/91 760). Compared with never users, ever and current users of HRT had a 22% and 14% increased risk of cataract surgery, respectively. A dose-response with longer HRT use resulting in a larger increase in cataract surgery risk was observed (p for trend <0.001). Among participants never used HRT, hormonal contraception had a protective effect against incident cataract surgery (hazards ratio: 0.87; 95% confidence interval: 0.80-0.94).

CONCLUSIONS

Use of HRT significantly increased the risk of cataract surgery, and hormonal contraception use had a protective effect on cataract surgery among HRT non-users. Further studies assessing the effect of different hormone types and doses are needed.

Association between recent pregnancy or hormonal contraceptive exposure and outcome of desmoid-type fibromatosis

BACKGROUND

The role of both hormonal contraception and pregnancy on the outcomes of desmoid-type fibromatosis (DF) is debatable.

MATERIALS AND METHODS

In the present study, we selected female patients of childbearing age from the prospective ALTITUDES cohort. The primary study endpoint was event-free survival (EFS), with an event defined as relapse or progression. We estimated the risk of events according to the use of hormonal contraception [estrogen-progestin (EP) and progestin] and pregnancy status using multivariate time-dependent models, controlling for major confounders.

RESULTS

A total of 242 patients (median age, 34.7 years) were included in the present study. The abdominal wall was the most common tumor site (51%). Patients were managed by active surveillance (80%) or surgery (20%). Pregnancy occurred within 24 months before, at the time of, and after DF diagnosis in 33%, 5%, and 10% of the cases, respectively. Exposure to hormonal contraception was documented within 24 months before, at the time of, and after diagnosis in 44%, 34%, and 39% of the cases, respectively. The 2-year EFS was 75%. After adjusting for DF location, tumor size, front-line treatment strategy, and hormonal contraception, we observed an increased risk of events occurring at 24 months after pregnancy [hazard ratio (HR) = 2.09, P = 0.018]. We observed no statistically significant association between the risk of events and current EP exposure (HR = 1.28, P = 0.65), recent EP exposure (within 1-24 months, HR = 1.38, P = 0.39), current progestin exposure (HR = 0.81, P = 0.66), or recent progestin exposure (HR = 1.05, P = 0.91).

CONCLUSIONS

In our study, a recent history of pregnancy was associated with an increased risk of progression/relapse in patients with newly diagnosed DF, whereas hormonal contraception did not demonstrate an association with progression/relapse.

Initiating Intramuscular Depot Medroxyprogesterone Acetate Increases Frequencies of Th17-like Human Immunodeficiency Virus Target Cells in the Genital Tract of Women in South Africa: A Randomized Trial

BACKGROUND

Cervicovaginal CD4+ T cells are preferential targets for human immunodeficiency virus (HIV) infection and have consequently been used as a proxy measure for HIV susceptibility. The ECHO randomized trial offered a unique opportunity to consider the association between contraceptives and Th17-like cells within a trial designed to evaluate HIV risk. In a mucosal substudy of the ECHO trial, we compared the impact of initiating intramuscular depot medroxyprogesterone acetate (DMPA-IM), copper-IUD, and the levonorgestrel (LNG) implant on cervical T cells.

METHODS

Cervical cytobrushes from 58 women enrolled in the ECHO trial were collected at baseline and 1 month after contraceptive initiation. We phenotyped cervical T cells using multiparameter flow cytometry, characterized the vaginal microbiome using 16s sequencing, and determined proteomic signatures associated with Th17-like cells using mass spectrometry.

RESULTS

Unlike the LNG implant or copper-IUD, DMPA-IM was associated with higher frequencies of cervical Th17-like cells within 1 month of initiation (P = .012), including a highly susceptible, activated population co-expressing CD38, CCR5, and α4β7 (P = .003). After 1 month, women using DMPA-IM also had more Th17-like cells than women using the Cu-IUD (P = .0002) or LNG implant (P = .04). Importantly, in women using DMPA-IM, proteomic signatures signifying enhanced mucosal barrier function were associated with the increased abundance of Th17-like cells. We also found that a non-Lactobacillus-dominant microbiome at baseline was associated with more Th17-like cells post-DMPA-IM (P = .03), although this did not influence barrier function.

CONCLUSIONS

Our data suggest that DMPA-IM-driven accumulation of HIV-susceptible Th17-like cells might be counteracted by their role in maintaining mucosal barrier integrity.

Hormonal therapies and venous thrombosis: Considerations for prevention and management

Background

Venous thromboses are well‐established complications of hormonal therapy. Thrombosis risk is seen with both hormonal contraceptive agents and with hormone replacement therapy for menopause and gender transition. Over the past several decades, large epidemiological studies have helped better define these risks.

Objectives

To review and discuss the differences in thrombosis risk of the many of hormonal preparations available as well as their interaction with patient‐specific factors.

Methods

We conducted a narrative review of the available literature regarding venous thrombosis and hormonal therapies including for contraception, menopausal symptoms, and gender transition.

Results

Thrombosis risk with estrogen‐containing compounds increases with increasing systemic dose of estrogen. While progesterone‐only–containing products are not associated with thrombosis, when paired with estrogen in combined oral contraceptives, the formulation of progesterone does impact the risk. These components, along with patient‐specific factors, may influence the choice of hormonal preparation. For patients who develop thrombosis on hormonal treatment, anticoagulation is protective against future thrombosis. Duration of anticoagulation is dependent on ongoing and future hormone therapy choice. Finally, the optimal management of hormone therapy for individuals diagnosed with prothrombotic illnesses such as COVID‐19 remains unclear.

Conclusions

When contemplating hormonal contraception or hormone replacement therapy, clinicians must consider a variety of factors including hormone type, dose, route, personal and family history of thrombosis, and other prothrombotic risk factors to make informed, personalized decisions regarding the risk of venous thrombosis.

Oral contraceptive use by formulation and breast cancer risk by subtype in the Nurses' Health Study II: a prospective cohort study

BACKGROUND

Oral contraceptive use has been associated with a higher breast cancer risk; however, evidence for the associations between different oral contraceptive formulations and breast cancer risk, especially by disease subtype, is limited.

OBJECTIVE

This study aimed to evaluate the associations between oral contraceptive use by formulation and breast cancer risk by disease subtype.

STUDY DESIGN

This prospective cohort study included 113,187 women from the Nurses' Health Study II with recalled information on oral contraceptive usage from 13 years of age to baseline (1989) and updated data on usage until 2009 collected via biennial questionnaires. A total of 5799 breast cancer cases were identified until the end of 2017. Multivariable Cox proportional hazards models estimated hazard ratios and 95% confidence intervals for the associations between oral contraceptive use and breast cancer risk overall and by estrogen and progesterone receptor and human epidermal growth factor receptor 2 status. Oral contraceptive use was evaluated by status of use (current, former, and never), duration of and time since last use independently and cross-classified, and formulation (ie, estrogen and progestin type).

RESULTS

Current oral contraceptive use was associated with a higher risk for invasive breast cancer (hazard ratio, 1.31; 95% confidence interval, 1.09-1.58) when compared with never use, with stronger associations observed for longer durations of current use (>5 years: hazard ratio, 1.56; 95% confidence interval, 1.23-1.99; ≤5 years: hazard ratio, 1.19; 95% confidence interval, 0.95-1.49). Among former users with >5 years since cessation, the risk was similar to that of never users (eg, >5 to 10 years since cessation: hazard ratio, 0.99; 95% confidence interval, 0.88-1.11). Associations did not differ significantly by tumor subtype. In analyses by formulation, current use of formulations containing levonorgestrel in triphasic (hazard ratio, 2.83; 95% confidence interval, 1.98-4.03) and extended cycle regimens (hazard ratio, 3.49; 95% confidence interval, 1.28-9.53) and norgestrel in monophasic regimens (hazard ratio, 1.91; 95% confidence interval, 1.19-3.06), all combined with ethinyl estradiol, was associated with a higher breast cancer risk when compared with never oral contraceptive use. No association was observed for current use of the other progestin types evaluated (norethindrone, norethindrone acetate, ethynodiol diacetate, desogestrel, norgestimate, and drospirenone), however, sample sizes were relatively small for some of the subgroups, limiting these analyses.

CONCLUSION

Current oral contraceptive use was associated with a higher risk for invasive breast cancer regardless of disease subtype, however, the risk in former users was comparable with never users 5 years after cessation. In analyses by progestin type, associations were observed for select formulations containing levonorgestrel and norgestrel. Assessment of the associations for newer progestin types (desogestrel, norgestimate, drospirenone) was limited by sample size, and further research on more recently introduced progestins is warranted.

Systemic hormonal contraception and risk of venous thromboembolism

INTRODUCTION

The increased risk of venous thromboembolism associated with the use of hormonal contraception is well recognized, but evidence regarding hormonal contraception containing natural estradiol is limited. This study aimed to assess the associations between the patterns of use of different systemic hormonal contraceptives and the risk of venous thromboembolism during 2017-2019.

MATERIAL AND METHODS

All fertile-aged women (15-49 years) living in Finland in 2017 and using hormonal contraception in 2017 and their 1:1 age- and residence-matched controls not using hormonal contraception in 2017 (altogether 587 559 women) were selected from the Prescription Centre. All incident venous thromboembolism cases during 2018-2019 and their 4:1 age-matched controls were further analyzed in a prospective nested case-control design to assess the associations between the use (starting, stopping, continuous vs no use) of different hormonal contraception types and venous thromboembolism.

RESULTS

Altogether, 1334 venous thromboembolism cases occurred during the follow-up period (incidence rate 1.14 per 1000 person-years, 95% confidence interval [CI] 1.08-1.20), with an incidence rate ratio of hormonal contraception vs no hormonal contraception use of 1.42 (95% CI 1.27-1.58). Compared with non-use, starting the use of gestodene and ethinylestradiol (adjusted odds ratio [aOR] 2.85; 95% CI 1.62-5.03), drospirenone and ethinylestradiol (aOR 1.55; 95% CI 0.98-2.44), desogestrel and ethinylestradiol (aOR 1.97; 95% CI 0.99-3.92), and transdermal patch releasing norelgestromin and ethinylestradiol (aOR 5.10; 95% CI 1.12-23.16), as well as continuing the use of gestodene and ethinylestradiol (aOR 2.60; 95% CI 1.61-4.21), drospirenone and ethinylestradiol (aOR 1.55; 95% CI 1.02-2.37), cyproterone-acetate and estrogen/ethinylestradiol (aOR 1.66; 95% CI 1.06-2.61), and vaginal ring releasing etonogestrel and ethinylestradiol (aOR 3.27; 95% CI 1.95-5.48) were associated with venous thromboembolism risk. Regarding the type of estrogen, the highest risk was associated with current use (vs non use in the previous 180 days) of ethinylestradiol-containing preparations (aOR 2.20; 95% CI 1.82-2.65), followed by estradiol-containing preparations (aOR 1.39; 95% CI 1.04-1.87) with no risk for progestin-only hormonal contraception. Current use of estradiol-containing preparations was not associated with venous thromboembolism risk after exclusion of cyproterone-acetate and estrogen/ethinylestradiol (aOR 1.05; 95% CI 0.66-1.66).

CONCLUSIONS

An increased risk of venous thromboembolism is associated with ethinylestradiol-containing combined preparations. The use of estradiol-containing combined preparations confers only a slightly increased risk, possibly driven by cyproterone-containing combined oral contraceptives, whereas the use of progestin-only contraception is not associated with venous thromboembolism.

Fluctuations in Metabolites and Bone Markers Across the Menstrual Cycle in Eumenorrheic Women and Oral Contraceptive Users

CONTEXT

Little is known about changes in circulating metabolites during the menstrual cycle and how use of oral contraceptives (OCs) affects these changes.

OBJECTIVES

To study fluctuations in circulating metabolite and bone marker levels during the menstrual/pill cycle in eumenorrheic women and OC users.

METHODS

Plasma samples were collected from 28 eumenorrheic women and 10 OC users at 7 to 9 time points across a menstrual/pill cycle. Longitudinal and cross-sectional analyses were performed to examine the cycle- and OC-induced variations in the plasma metabolite and bone turnover marker levels.

RESULTS

In eumenorrheic women, plasma levels of alanine, glutamine, threonine, and tyrosine varied significantly across the menstrual cycle, and all dropped to the lowest level around day 21 of the menstrual cycle. These amino acid concentrations were negatively correlated with fluctuations in progesterone and/or estrogen levels. A between-group analysis showed that plasma levels of alanine, glutamine, glycine, proline, and tyrosine were lower in OC users than in nonusers. Concomitantly, plasma C-terminal telopeptide of type I collagen (CTX) and N-terminal propeptide of type I procollagen (PINP) levels were lower in OC users. Intriguingly, when all data were pooled, variations in CTX and PINP levels were positively correlated with fluctuations in proline and glycine concentrations (r > 0.5 or 0.3 < r < 0.5, P < 0.05).

CONCLUSIONS

The menstrual cycle and the use of OCs alter plasma levels of metabolites and bone turnover markers in young women. While the impact of these findings remains to be established, the lower glycine level among OC users and the accompanying lower CTX level supports that the use of OCs lowers collagen turnover in young women and may thereby have long-term implications for bone health among OC users.

Curricular Considerations for Preparing Student Pharmacists to Prescribe Hormonal Contraception

In 2014, the pharmacist's role in the United States expanded to include prescribing hormonal contraception, and this practice is currently addressed by policy in 14 states and the District of Columbia. Training and education requirements for this expanded scope of practice vary between states and are changing rapidly. The objective of this review is to examine how student pharmacists are taught to provide contraceptive care, specifically for prescribing ongoing hormonal contraception and emergency contraception, and to identify potential gaps in the United States pharmacy curricula related to contraception. Despite steady adoption into community pharmacy practice, there is sparse literature assessing educational methods used to teach contraceptive care. This review offers recommendations to promote consistent and comprehensive student pharmacist education in providing contraceptive care across institutions, regardless of state policy status.

Contribution of Etiologic Cofactors to CIN3+ Risk Among Women With Human Papillomavirus-Positive Screening Test Results

OBJECTIVE

The US screening and management guidelines for cervical cancer are based on the absolute risk of precancer estimated from large clinical cohorts and trials. Given the widespread transition toward screening with human papillomavirus (HPV) testing, it is important to assess which additional factors to include in clinical risk assessment to optimize management of HPV-infected women.

MATERIALS AND METHODS

We analyzed data from HPV-infected women, ages 30-65 years, in the National Cancer Institute-Kaiser Permanente Northern California Persistence and Progression study. We estimated the influence of HPV risk group, cytology result, and selected cofactors on immediate risk of cervical intraepithelial neoplasia grade 3 or higher (CIN 3+) among 16,094 HPV-positive women. Cofactors considered included, age, race/ethnicity, income, smoking, and hormonal contraceptive use.

RESULTS

Human papillomavirus risk group and cytology test result were strongly correlated with CIN 3+ risk. After considering cytology and HPV risk group, other cofactors (age, race/ethnicity, income, smoking, and hormonal contraceptive use) had minimal impact on CIN 3+ risk and did not change recommended management based on accepted risk thresholds. We had insufficient data to assess the impact of long-duration heavy smoking, parity, history of sexually transmitted infection, or immunosuppression.

CONCLUSIONS

In our study at the Kaiser Permanente Northern California, the risk of CIN 3+ was determined mainly by HPV risk group and cytology results, with other cofactors having limited impact in adjusted analyses. This supports the use of HPV and cytology results in risk-based management guidelines.

Systems Analysis Reveals Contraceptive-Induced Alteration of Cervicovaginal Gene Expression in a Randomized Trial

Hormonal contraceptives (HCs) are vital in managing the reproductive health of women. However, HC usage has been linked to perturbations in cervicovaginal immunity and increased risk of sexually transmitted infections. Here, we evaluated the impact of three HCs on the cervicovaginal environment using high-throughput transcriptomics. From 2015 to 2017, 130 adolescent females aged 15-19 years were enrolled into a substudy of UChoose, a single-site, open-label randomized, crossover trial (NCT02404038) and randomized to injectable norethisterone-enanthate (Net-En), combined oral contraceptives (COC), or etonorgesterol/ethinyl-estradiol-combined contraceptive vaginal ring (CCVR). Cervicovaginal samples were collected after 16 weeks of randomized HC use and analyzed by RNA-Seq, 16S rRNA gene sequencing, and Luminex analysis. Participants in the CCVR arm had a significant elevation of transcriptional networks driven by IL-6, IL-1, and NFKB, and lower expression of genes supporting epithelial barrier integrity. An integrated multivariate analysis demonstrated that networks of microbial dysbiosis and inflammation best discriminated the CCVR arm from the other contraceptive groups, while genes involved in epithelial cell differentiation were predictive of the Net-En and COC arms. Collectively, these data from a randomized trial represent the most comprehensive "omics" analyses of the cervicovaginal response to HCs and provide important mechanistic guidelines for the provision of HCs in sub-Saharan Africa.

Association of Hormonal Contraception with Meningioma Location in Indonesian Patients

Background:

Meningioma is the most common primary intracranial tumor. Previous studies have shown the possible association between hormonal contraceptive use and meningioma location. Therefore, this study aimed to analyze the association between the history of hormonal contraceptive use and the location of meningioma in the Indonesian population.

Methods:

In total, 99 histologically confirmed female meningioma patients admitted to Dr. Sardjito General Hospital Yogyakarta, Indonesia, were included in this study. Data on hormonal contraception and other variables were collected from medical records. Meningioma locations were determined from brain Magnetic Resonance Imaging (MRI) or Computerized Tomography (CT) scan before surgery.

Results:

Seventy-two (72.7%) patients had a history of hormonal contraceptive use. The subjects consist of 83 (83.8%) WHO grade I and 16 (16.2%) WHO grade II and III tumors. A total of 57 (57.6%) tumors were located in the spheno-orbital region. We found a significant association between hormonal contraceptive use and meningioma location in the spheno-orbital region (Odds ratio (OR) 2.573, p=0.038). This resulted in the patients in the hormonal contraception group having more visual impairment (p=0.044).

Conclusion:

The use of hormonal contraception is associated with the location of meningioma in the spheno-orbital region.

Discontinuation of hormonal contraception due to changes in mood and decreases in sexual desire: the role of adverse childhood experiences

PURPOSE

To evaluate if adverse childhood experiences are associated with hormonal contraception discontinuation due to mood and sexual side effects.

MATERIALS AND METHODS

Women, ages 18-40 (N = 826), with current and/or previous hormonal contraceptive use completed surveys on demographics, contraceptive history, and the Adverse Childhood Experiences Questionnaire. We characterised women into high (≥2 adverse experiences) and low (0 or 1) adverse childhood experience groups. We calculated risk ratios for associations between adverse childhood experiences and outcomes of interest using log binomial generalised linear models, and adjusted for relevant demographic variables.

RESULTS

Women in the high adverse childhood experiences group (n = 355) were more likely to report having discontinued hormonal contraception due to decreases in sexual desire (adjusted risk ratio 1.44, 1.03-2.00, p = .030). Covariates included age, current hormonal contraception use, and various demographic variables associated with discontinuation. Adverse childhood experiences were not associated with mood or sexual side effects among current (n = 541) hormonal contraceptive users.

CONCLUSIONS

Self-reported adverse childhood experiences were associated with greater likelihood of discontinuing hormonal contraception due to behavioural side effects, particularly decreases in sexual desire. Identification of risk factors for behavioural side effects can assist patients and clinicians in making informed choices on contraception that minimise risk of early discontinuation.

Reproductive changes among women in their 40s: A cross-sectional study

INTRODUCTION

The aim was to describe and compare changes in the reproductive pattern of women in their 40s observed over a decade in Scandinavia.

MATERIAL AND METHODS

Cross-sectional study using the total population of women aged 40-49 years between 2008-2018 in Denmark, Norway and Sweden (on average n = 1.5 million). Aggregated data concerning birth and induced abortion rate were collected and analyzed from national health registers. National data on redeemed prescriptions of hormonal contraceptives in the three countries were collected from prescription registers. Births after spontaneous and assisted conceptions were identified by using cross-linked data on deliveries from the Medical Birth Registers and National Registers of Assisted Reproduction in the three countries.

RESULTS

Use of hormonal contraception increased among women aged 40-44 years in Denmark from 24% to 31%, in Sweden from 27% to 30%, and in Norway from 22% to 24%. The levonorgestrel-releasing intrauterine device was the most frequently used method in all countries. Birth rates among women 40-44 years increased continuously from 9.5 to 12/1000 women in Denmark and from 11.7 to 14.3/1000 in Sweden, but remained stable in Norway at ~11/1000 women. There was a doubling of assisted conceptions in Denmark from 0.71 to 1.71/1000 women, Sweden from 0.43 to 0.81/1000 and Norway from 0.25 to 0.53/1000 women 40-49 years of age. Sweden had the highest induced abortion rate (7.7 to 8.1/1000 women) in women aged 40-49 years during the study period.

CONCLUSIONS

From 2008 to 2018, birth rates continuously increased among women aged 40-49 years in Denmark and Sweden and births resulting from assisted reproductive technology doubled in all three countries.
