RESUMEN

INTRODUCTION: The subject of this guideline from the Institute of Family Medicine at the University of Zurich (IHAMZ) is the management of venous thrombosis. The review summarizes the current evidence and recommendations from international guidelines (1-6). The IHAMZ-guidelines focus on primary care, they also provide guidance on the coordination of general and specialist medical care as well as on the transition between outpatient and hospital care taking into account the special features of the Swiss healthcare system. The guideline is devided in two parts. Part 1 discusses the diagnosis and treatment of deep vein thrombosis (DVT). A validated algorithm is recommended for the diagnostic process, which begins with the assessment of the clinical probability. With the inclusion of the D-dimer test, the need for subsequent imaging diagnostics can be reduced. The differences between the evaluation of an initial and recurrent DVT are shown and the indications and scope of evidence-based environmental diagnostics (thrombophilia and tumor search) are presented. All patients with DVT should receive anticoagulation (AC) for 3-6 months, as there is a high risk of recurrence with AC 3 months. The duration of the subsequent secondary prophylaxis depends on the presumed risk of recurrence on the one hand and the risk of bleeding on the other. Part 2 is dedicated to special thrombosis situations such as shoulder-arm vein thrombosis (SAVT), cancer-associated thrombosis (CAT) and superficial vein thrombosis (SVT). The article on hormone- and pregnancy-associated DVT, developed together with the Department of Gynecology at the University Hospital of Zurich, discusses the importance of hormonal contraception and menopausal hormone replacement therapy (HRT) as a thrombogenic risk factor as well as special features in the diagnosis and treatment of thrombosis in pregnancy.

RESUMEN

OBJECTIVE: To evaluate the impact of age on disease recurrence in idiopathic subglottic stenosis (iSGS) patients. METHODS: This was a retrospective chart review of iSGS patients treated with laser wedge excision. Patients did not have prior surgery. Survival rates free of recurrence were estimated using the Kaplan-Meier methods, and associations were evaluated using Cox Proportional Hazards models. RESULTS: Eighty-five female patients were included in the study. Most patients (68%) were postmenopausal, had first period at or before 13 years of age, had at least one full-term pregnancy (82%), were not undergoing hormone replacement therapy (93%), were not using hormonal birth control (88%), and were either partially or completely compliant with triple therapy regime (80%). There was a statistically significant average reduction in risk of recurrence of 5% for every additional year of age (p < 0.0001). When compared to patients older than 65 years of age, patients less than 35 were nearly 10 times more likely to recur (p = 0.002), and patients 55-65 and 45-55 years of age were 8 and 5 times more likely to recur, respectively (p = 0.003 and 0.009). Additionally, females on birth control showed decreased risk of recurrence of 74% compared with their counterparts (p = 0.04). CONCLUSION: This is the first study to demonstrate an inverse relationship between age and disease recurrence in patients with iSGS following surgery. Using age as a surrogate for menopausal status, these results suggest that increased age and/or birth control provide a protective effect through decreased recurrence rates, possibly mediated by decreased estrogen levels. LEVEL OF EVIDENCE: 4 Laryngoscope, 2024.

RESUMEN

Dr. Elizabeth Bagshaw, an esteemed figure among Canada's female physicians, devoted over seven decades to advancing obstetrics and reproductive health. She defied conventional norms by pursuing medical education and graduating from the Ontario Medical College for Women in 1905. Throughout her illustrious career, Bagshaw demonstrated exceptional perseverance, navigating familial obligations following her father's untimely passing during her academic pursuits.  Establishing her practice in Hamilton, Ontario, Bagshaw delivered over 3,000 neonates, frequently offering pro bono care to immigrant populations. Notably in 1932, Bagshaw assumed the role of Medical Director of Canada's first birth control clinic, challenging restrictive legislation and paving the way for the legalization of contraception in 1969. Bagshaw's efforts provided women with vital reproductive health services and information, significantly impacting public attitudes and legislation.  Beyond her medical practice, Bagshaw also played a pivotal role in mitigating public health crises, including the Spanish flu, and ventured into politics with a city council campaign in 1934, supported by The Women's Civic Club. Her extensive contributions earned her numerous accolades, including posthumous induction into the Canadian Medical Hall of Fame in 2007.  Bagshaw's enduring legacy is reflected in the Elizabeth Bagshaw Clinic, which continues to offer reproductive and abortion care in a confidential and supportive setting. Bagshaw's pioneering work significantly advances health equity and women's reproductive rights, leaving a lasting impact on healthcare worldwide. Her life and achievements underscore her role as a tireless advocate for women's health and a transformative influence in medical history.

RESUMEN

PURPOSE: Rural adolescent pregnancy is a serious public health issue, largely due to low contraceptive use. Existing data focuses on urban populations. Using a positive youth development framework, we examine associations between modifiable protective factors and birth control use in a rural population. METHODS: Prior to an evidence-based health education program, students in 10th grade health class in two low-to-middle income rural schools completed surveys. For contraceptive use at last sex, students could check all methods that applied which were collapsed into three rank-ordered categories: none, condoms only, and hormonal contraception. Predictor variables included sexual self-efficacy (six items, α = 0.66, "able to say no"), parent connectedness (five items, α = 0.94, "satisfaction with your parent/guardian?"), language acculturation (one item, "in your home do you speak…"), school connectedness (five items, α = 0.85, "I feel close to people at my school") and adverse childhood experiences (eight item score). These variables were entered into a multivariable logistic ordinal regression. RESULTS: The sample (N = 287) was 52% female, 48% LatinX and 49% white. Higher sexual self-efficacy and parent connectedness scores significantly increased the odds of using more effective birth control. Higher language acculturation (more likely to speak another language at home) suggested less likely to use more effective birth control. School connection and adverse childhood experiences were not significant in the final model. DISCUSSION: Contraception focused interventions in rural communities should address modifiable protective factors, such as self-efficacy and parent connection. Interventions need to be trauma-informed and language accessible.

RESUMEN

Background: TikTok has increasingly become a source of information about reproductive health. Patients seeking health information about oral contraception on TikTok may be influenced by videos containing misinformation or biased information. Objective: This social media infodemiological study aims to provide a descriptive content analysis of the quality and reliability of oral contraceptive health information on TikTok. Study Design: Researchers screened 1,000 TikTok videos from December 2022 to March 2023 retrieved under various search terms related to oral contraceptives. Data, including engagement metrics such as views, likes, comments, saves, and shares, were recorded. Video content including contraceptive methods discussed, efficacy, tolerability, and side effects were recorded. Two reviewers independently used a modified DISCERN criteria and Global Quality Scale (GQS) to assess the quality and reliability of information for each video. Results: Five hundred seventy-four videos were analyzed after applying exclusion criteria. Videos had a median length of 27 seconds (Q1=13sec, Q3=57sec) and received a median of 35,000 total views (Q1=4856 views, Q3=411,400 views) and 166 views per day (Q1=28 views per day, Q3=2021 views per day). Video creators were 83.3% female and 58.7% white. The mean modified DISCERN score was 1.63 (SD=1.06) and the mean GQS score was 2.28 (SD=1.37). Video creators were 83.3% female and 58.7% white. The mean modified DISCERN score was 1.63 (SD=1.06) and the mean GQS score was 2.28 (SD=1.37). The most common topic discussed in the videos was the effects of contraception. Healthcare professionals had significantly higher DISCERN and GQS scores (p<.001) than non-healthcare professionals. However, they received fewer views, likes, and comments on their videos (p<.001). Healthcare professionals were 86 times more likely than non-healthcare professionals to post educational videos (p<.001). However, non-educational content received significantly more views, likes, and comments than educational content (p<.001). Conclusion: TikTok videos related to oral contraceptive health had low quality and reliability of information. The majority of videos were made by non-healthcare providers, and the most common topic discussed was the effects of contraception. Videos made by healthcare professionals contained more reliable contraceptive information, but received less engagement than videos made by non-healthcare professionals. Healthcare providers should consider the prevalence of poor-quality information about oral contraceptives on social media when counseling and educating patients about reproductive health.

RESUMEN

BACKGROUND: Patients find technology tools to be more approachable for seeking sensitive health-related information, such as reproductive health information. The inventive conversational ability of artificial intelligence (AI) chatbots, such as ChatGPT (OpenAI Inc), offers a potential means for patients to effectively locate answers to their health-related questions digitally. OBJECTIVE: A pilot study was conducted to compare the novel ChatGPT with the existing Google Search technology for their ability to offer accurate, effective, and current information regarding proceeding action after missing a dose of oral contraceptive pill. METHODS: A sequence of 11 questions, mimicking a patient inquiring about the action to take after missing a dose of an oral contraceptive pill, were input into ChatGPT as a cascade, given the conversational ability of ChatGPT. The questions were input into 4 different ChatGPT accounts, with the account holders being of various demographics, to evaluate potential differences and biases in the responses given to different account holders. The leading question, "what should I do if I missed a day of my oral contraception birth control?" alone was then input into Google Search, given its nonconversational nature. The results from the ChatGPT questions and the Google Search results for the leading question were evaluated on their readability, accuracy, and effective delivery of information. RESULTS: The ChatGPT results were determined to be at an overall higher-grade reading level, with a longer reading duration, less accurate, less current, and with a less effective delivery of information. In contrast, the Google Search resulting answer box and snippets were at a lower-grade reading level, shorter reading duration, more current, able to reference the origin of the information (transparent), and provided the information in various formats in addition to text. CONCLUSIONS: ChatGPT has room for improvement in accuracy, transparency, recency, and reliability before it can equitably be implemented into health care information delivery and provide the potential benefits it poses. However, AI may be used as a tool for providers to educate their patients in preferred, creative, and efficient ways, such as using AI to generate accessible short educational videos from health care provider-vetted information. Larger studies representing a diverse group of users are needed.

RESUMEN

With the increase in the world's population, contraception is crucial in population control strategies. Majority of contraceptives produced today are targeted at women; many of whom experience side effects, leading to the discontinuation of these contraceptives after a year of use. As the use of condoms and vasectomies has been subjected to scrutiny, it is necessary for the development of male birth control (BC). Attempts to achieve this include hormonal and non-hormonal contraception. Hormonal contraception prevents the production of the sperm in the testes; but this mode of BC has been found to be ineffective while also causing behavioural changes in men. In contrast, non-hormonal male contraception focuses on rendering the sperm immotile to prevent fertilization post-copulation. Soluble adenylate cyclase is an area of research that has shown promise in this field. Furthermore, two inhibitors, TDI-10299 and TDI-11861, have been developed and tested, with the latter, showing greater potency and longer activity, in mice models. Overall, by developing non-hormonal male contraceptives, men will have more control over their reproductive health. Nonetheless, before such contraceptives can be made widely available, it is important that further research takes place to ensure the safety and effectiveness of these methods.

RESUMEN

BACKGROUND: Prescribed contraception is used worldwide by over 400 million women of reproductive age. Monitoring contraceptive use is a major public health issue that usually relies on population-based surveys. However, these surveys are conducted on average every 6 years and do not allow close follow-up of contraceptive use. Moreover, their sample size is often too limited for the study of specific population subgroups such as people with low income. Health administrative data could be an innovative and less costly source to study contraceptive use. OBJECTIVE: We aimed to explore the potential of health administrative data to study prescribed contraceptive use and compare these data with observations based on survey data. METHODS: We selected all women aged 15-49 years, covered by French health insurance and living in France, in the health administrative database, which covers 98% of the resident population (n=14,788,124), and in the last French population-based representative survey, the Health Barometer Survey, conducted in 2016 (n=4285). In health administrative data, contraceptive use was recorded with detailed information on the product delivered, whereas in the survey, it was self-declared by the women. In both sources, the prevalence of contraceptive use was estimated globally for all prescribed contraceptives and by type of contraceptive: oral contraceptives, intrauterine devices (IUDs), and implants. Prevalences were analyzed by age. RESULTS: There were more low-income women in health administrative data than in the population-based survey (1,576,066/14,770,256, 11% vs 188/4285, 7%, respectively; P<.001). In health administrative data, 47.6% (7034,710/14,770,256; 95% CI 47.6%-47.7%) of women aged 15-49 years used a prescribed contraceptive versus 50.5% (2297/4285; 95% CI 49.1%-52.0%) in the population-based survey. Considering prevalences by the type of contraceptive in health administrative data versus survey data, they were 26.9% (95% CI 26.9%-26.9%) versus 27.7% (95% CI 26.4%-29.0%) for oral contraceptives, 17.7% (95% CI 17.7%-17.8%) versus 19.6% (95% CI 18.5%-20.8%) for IUDs, and 3% (95% CI 3.0%-3.0%) versus 3.2% (95% CI 2.7%-3.7%) for implants. In both sources, the same overall tendency in prevalence was observed for these 3 contraceptives. Implants remained little used at all ages, oral contraceptives were highly used among young women, whereas IUD use was low among young women. CONCLUSIONS: Compared with survey data, health administrative data exhibited the same overall tendencies for oral contraceptives, IUDs, and implants. One of the main strengths of health administrative data is the high quality of information on contraceptive use and the large number of observations, allowing studies of subgroups of population. Health administrative data therefore appear as a promising new source to monitor contraception in a population-based approach. They could open new perspectives for research and be a valuable new asset to guide public policies on reproductive and sexual health.

RESUMEN

OBJECTIVES: The efficacy and availability of contraception have changed in the last several decades; however, unintended pregnancies continue to be an issue in Australia. This study aimed to describe trends in contraception in women attending a sexual health service over 9 years. STUDY DESIGN: Repeated cross-sectional study. METHODS: Women aged 16-49 years attending Melbourne Sexual Health Centre between 2011 and 2020 were included. Women were asked what methods of contraception they currently use. Contraception were categorised into long-acting reversible contraception (LARC; e.g. intrauterine devices and implants classified as highly effective), moderately effective contraception (e.g. oral contraception pill), less effective contraception (e.g. condom and withdrawal) and no contraception, as defined by US Centers for Disease Control and Prevention guidelines. Multivariable logistic regression was used to examine the factors associated with the use of moderate-high-efficacy contraception. RESULTS: A total of 38,288 women were included with a median age of 25 (interquartile range: 22-29). Between 2011 and 2020, there was a decreasing trend in condom (63.3%-56.1%; Ptrend <0.001) and oral contraception (27.2%-20.5%; Ptrend <0.001) use, whilst there was an increasing trend in the use of LARCs: implant (4.6%-6.0%; Ptrend = 0.002) and intrauterine device (2.8%-11.8%; Ptrend <0.001). Increasing age was associated with decreased odds of using moderate-high-efficacy contraception (Ptrend <0.001). Compared with Oceanian-born women, Asian (adjusted odds ratios [aOR] = 0.63, 95% confidence interval [CI]: 0.56-0.72) and Middle Eastern-born women (aOR = 0.60, 95% CI: 0.48-0.74) had lower odds of using moderate-high-efficacy contraception, whilst European (aOR = 1.23, 95% CI:1.07-1.41) and North American-born women (aOR = 1.51, 95% CI: 1.22-1.87) had higher odds of using moderate-high-efficacy contraception. CONCLUSIONS: Between 2011 and 2020, LARC use has increased, whilst less effective contraceptives, such as condom and oral contraception, have decreased among women at Melbourne Sexual Health Centre. Further research is required to understand age and ethnic disparities in contraception methods for future family planning programmes.

RESUMEN

In this study, the spectrophotometric method integrated with continuous wavelet transform (CWT) and coupled discrete wavelet transform (DWT) with fuzzy inference system (FIS) was developed for the simultaneous determination of ethinyl estradiol (EE) and drospirenone (DP) in combined oral contraceptives (COCs). The CWT approach was performed in the linearity range of 0.6-6 µg/mL for EE and 0.9 to 18 µg/mL for DP. Biorthogonal with an order of 1.3 (bior1.3) at a wavelength of 216 nm and Daubechies with an order of 2 (db2) at a wavelength of 278 nm were selected as the best wavelet families for obtaining the best zero crossing point for EE and DP, respectively. The limit of detection (LOD) of 0.7677 and 0.3222 µg/mL and the limit of quantification (LOQ) of 2.326 and 0.9765 µg/mL were obtained for EE and DP, respectively. The mean recovery of 103.24% and 99.77%, as well as root mean square error (RMSE) of 0.1896 and 0.1969, were found for EE and DP, respectively. In the DWT, the absorption of the mixtures was decomposed using different wavelets named db4, db2, Symlet2 (sym2), and bior1.3. Each of the wavelet outputs was dimension reduced by the principal component analysis (PCA) method and considered as FIS input. The wavelet of db4 with the coefficient of determination (R2) of 0.9979, RMSE of 0.0968, and mean recovery of 100.63% was chosen as the best one for the EE, while bior1.3 with R2 of 0.9955, RMSE of 0.4055, and mean recovery of 101.93% was selected for DP. These methods were successfully used to analyze the EE and DP simultaneously in tablet pharmaceutical formulation without any separation step. The suggested methods were compared with a reference method (HPLC) using analysis of variance (ANOVA) at a 95% confidence level, and no significant difference was observed in terms of accuracy. The suggested chemometric methods are reliable, rapid, and inexpensive, and can be used as an environmentally friendly alternative to HPLC for the simultaneous estimation of the mentioned drugs in commercial pharmaceutical products.

RESUMEN

BACKGROUND: Nearly 40% of unplanned pregnancies in the USA are the result of inconsistent or incorrect contraceptive use. Finding ways to increase women's comfort and satisfaction with contraceptive use is therefore critical to public health. One promising pathway for improving patient outcomes is through the use of digital decision aids that assist women and their physicians in choosing a contraceptive option that women are comfortable with. Testing the ability of these aids to improve patient outcomes is therefore a necessary first step toward incorporating this technology into traditional physician appointments. PURPOSE: To evaluate the effectiveness of a novel contraceptive decision aid at minimizing decisional conflict and increasing comfort with contraception among adult women. METHODS: In total, 310 adult women were assigned to use either the Tuune contraceptive decision aid or a control aid modeled after a leading online contraceptive prescriber's patient intake form. Participants then completed self-report measures of decisional conflict, contraceptive expectations, satisfaction, and contraceptive use intentions. Individual between-subjects analysis of variance (ANOVA) models were used to examine these outcomes. RESULTS: Women using the Tuune decision aid (vs. those using the control aid) reported lower decisional conflict, more positive contraceptive expectations, greater satisfaction with the decision aid and recommendation, and more positive contraceptive use intentions. CONCLUSIONS: Use of Tuune improved each of the predicted patient outcomes relative to a control decision aid. Online decision aids, particularly when used alongside physician consultations, may be an effective tool for increasing comfort with contraceptive use. CLINICAL TRIALS REGISTRATION #: NCT05177783, ClinicalTrials.gov, https://clinicaltrials.gov/ct2/show/NCT05177783.

Digital decision aids that help women and their physicians choose contraceptive options that women are most comfortable with present one promising way to improve contraceptive use outcomes, such as avoiding unplanned pregnancies. However, current decision aids have been found to struggle in helping improve women's satisfaction with and confidence in their contraceptive choices. The aim of this study was to test the effectiveness of a new digital decision aid, named Tuune, at helping improve women's confidence and comfort with contraception. Three hundred and ten adult women were randomly assigned to use and then receive a contraceptive recommendation from either the Tuune decision aid or a control aid designed after leading traditional health intake forms. Women's confidence and satisfaction with the aids, as well as their contraceptive recommendation, were then compared between groups. We found good evidence to suggest that women using the Tuune contraceptive decision aid were more satisfied and positive about their contraceptive choices and reported greater intentions to use contraception with increased confidence compared to women who used the control decision aid. New online decision aids, like Tuune, may be an effective tool for increasing women's comfort and experiences using contraception.

RESUMEN

INTRODUCTION: Active and passive surveillance studies have found that a greater proportion of females report adverse events (AE) following receipt of either the COVID-19 or seasonal influenza vaccine compared to males. In a predominately young adult female population of healthcare workers, we sought to determine the intersection of biological sex and sociocultural gender differences in prospective active reporting of vaccine outcomes, which remains poorly characterized. METHODS: This cohort study enrolled Johns Hopkins Health System healthcare workers (HCWs) who were recruited from the mandatory annual fall 2019-2022 influenza vaccine and the fall 2022 COVID-19 bivalent vaccine campaigns. Vaccine recipients were enrolled the day of vaccination and AE surveys were administered two days post-vaccination for bivalent COVID-19 and influenza vaccine recipients. Data were collected regarding the presence of a series of solicited local and systemic AEs. Open-ended answers about participants' experiences with AEs also were collected for the COVID-19 vaccine recipients. RESULTS: Females were more likely to report local AEs after either influenza (OR = 2.28, p = 0.001) or COVID-19 (OR = 2.57, p = 0.008) vaccination compared to males, regardless of age or race. Males and females had comparable probabilities of reporting systemic AEs after either influenza (OR = 1.18, p = 0.552) or COVID-19 (OR = 0.96, p = 0.907) vaccination. Hormonal birth control use did not impact the rates of reported AEs following influenza vaccination among reproductive-aged female HCWs. Women reported more interruptions in their daily routine following COVID-19 vaccination than men and were more likely to seek out self-treatment. More women than men scheduled their COVID-19 vaccination before their days off in anticipation of AEs. CONCLUSIONS: Our findings highlight the need for sex- and gender-inclusive policies to inform more effective mandatory occupational health vaccination strategies. Further research is needed to evaluate the potential disruption of AEs on occupational responsibilities following mandated vaccination for healthcare workers, a predominately female population, and to more fully characterize the post-vaccination behavioral differences between men and women.

Research that addresses both the sex and gender differences of vaccine outcomes and behaviors is lacking. In this survey study of healthcare workers, comprised of mostly reproductive-aged females/women, we investigated biological sex (male/female) and gender (man/woman) differences in vaccine adverse events and outcomes following either influenza or bivalent COVID-19 vaccination.Regardless of age or race, females were more likely to report local (at injection site), but not systemic (whole body), adverse events than males, consistent across influenza and bivalent COVID-19 vaccine cohorts. Sex hormones are hypothesized to play a role in the differences in immune response following vaccination between males and females. We investigated if hormonal birth control use among females may be associated with differences in vaccine adverse events among the influenza vaccine cohort. However, there was no difference in the likelihood of reporting adverse events between birth control users and non-users. Based on open-ended responses to survey questions, women were found to report more interruptions to their daily routine than men following COVID-19 vaccination. Women were also more likely to seek out self-treatment with over-the-counter medication and intentionally schedule their vaccination around days off in anticipation of adverse events.With nearly 80% of healthcare jobs held by women, even higher for direct patient care positions like nursing, females/women may be disproportionately impacted by mandated annual vaccinations. Vaccinations are necessary for the prevention of disease transmission; however, our findings highlight a need for more equitable occupational vaccine strategies that consider both sex and gender differences.

RESUMEN

OBJECTIVE: To systematically review the effect of contraceptive methods following gestational trophoblastic disease (GTD) on timing of beta-human chorionic gonadotropin (hCG) remission, risk of post-molar gestational trophoblastic neoplasia (GTN), risk of unintended incident pregnancy, and interactions between contraceptive methods and disease treatment. STUDY DESIGN: We conducted a search of primary literature with search terms related to GTD and contraception through April 2023 in PubMed and extrapolated our search to other platforms. Randomized controlled trials, observational studies and case reports were eligible for inclusion if they reported on patients with known GTD who received a contraceptive method for pregnancy prevention. Data was abstracted on our main outcomes of interest: timing of beta-hCG remission, risk of post-molar GTN, risk of unintended incident pregnancy, and interactions between contraceptive methods and cancer-directed systemic disease treatment (e.g., chemotherapy). At least two authors reviewed manuscripts at each screening stage with consensus reached before data extraction. Quality assessment checklists were used to assess risk of bias for the different study types. RESULTS: Five thousand one hundred and five studies were identified in the database search, of which 42 were included for analysis. Eight thousand two hundred and ninety four participants were evaluated. Over half of the studies were case reports and only two were randomized controlled trials. While there was sparse data on all outcomes, no differences were noted in beta-hCG monitoring, risk of post-molar GTN or incident pregnancies between different contraceptive types. Interactions between contraceptive methods and cancer-directed systemic disease treatment (e.g., chemotherapy) or specific adverse events of contraceptive methods were not identified. CONCLUSIONS: Data on contraceptive use following GTD is limited, but use of both hormonal and non-hormonal modern contraceptive methods appears safe. Counseling patients on the full range of contraceptive methods is important to help patients achieve their reproductive health goals and minimize the risk of disease progression through incomplete beta-hCG monitoring prior to future pregnancy. IMPLICATIONS: Hormonal and non-hormonal contraceptive options may be used by patients following gestational trophoblastic disease without apparent changes in beta-hCG regression or risk of post-molar gestational trophoblastic neoplasia.

RESUMEN

Many female military service members choose to use hormonal contraception to prevent pregnancy and/or to control or suppress menses. Hormonal contraception, which comes in many different forms based on dose, estrogen/progestin type, and route of administration (oral, vaginal, transdermal, implant, intrauterine device, injectable), may cause side effects, some of which can influence military medical readiness, or the health status necessary to perform assigned missions. This expert review summarizes the evidence around common military-relevant side effects of hormonal contraception that could impact readiness, including effects on weight and body composition, bone health, psychological health, and physical performance, and serves as a tool for uniformed and civilian clinicians counseling female service members about hormonal contraception. Current evidence suggests some hormonal contraception can lead to weight and fat gain, may modulate susceptibility to mood or mental health disorders, and could impact bone mineral density and stress fracture risk; more research is needed on physical performance effects. Clinicians must be familiar with readiness considerations of each type of hormonal contraception to provide comprehensive patient education and allow for optimal shared decision-making about hormonal contraception use among female Service members. Considering the relative lack of data on the effects of nonoral hormonal contraception routes on readiness outcomes and the growing interest in long-acting reversible contraceptives among female service members, future research should continue to investigate effects of all hormonal contraception methods available to service members.

RESUMEN

Introduction: School-based health centers (SBHCs) are an evidence-based model for providing contraceptives to adolescents. SBHCs ability to provide reproductive health services is often limited by school district policies, state laws, and health center policies. Methods: We used data from the Teens Exploring and Managing Prevention (TEMPO) study to document demographic characteristics and birth control methods among patients at four SBHCs in New Mexico. A total of 264 teens were included in the baseline data collection at SBHCs in New Mexico. A baseline survey was administered via iPad, that specifically focused on questions related to sexual experiences and sexual health topics. Baseline questions included demographic questions, gender identity, sexual orientation, reasons for visits, reproductive practices, and birth control methods. Descriptive statistics were calculated, including means and standard deviations for continuous variables and categorical frequencies. Results: Our findings present reproductive health behaviors among New Mexican patients attending schools with SBHCs. More than 74% of respondents were Hispanic or Latino. The most common reason teens went to the SBHC was for birth control, and just 62% of teens reported using birth control methods in the past. Discussion: These behaviors are essential for policymakers to consider as they address policy gaps, the complex landscape of parental permission, reproductive rights, and health as a human right.

RESUMEN

Hormonal contraceptives are widely prescribed due to their effectiveness and convenience and have become an integral part of family planning strategies worldwide. In the United States, approximately 65% of reproductive-aged women are estimated to be using contraceptive options, with approximately 33% using one or a combination of hormonal contraceptives. While these methods have undeniably contributed to improved reproductive health, recent studies have raised concerns regarding their potential effect on metabolic health. Despite widespread anecdotal reports, epidemiological research has been mixed as to whether hormonal contraceptives contribute to metabolic health effects. As such, the goals of this study were to assess the adipogenic activity of common hormonal contraceptive chemicals and their mixtures. Five different models of adipogenesis were used to provide a rigorous assessment of metabolism-disrupting effects. Interestingly, every individual contraceptive (both estrogens and progestins) and each mixture promoted significant adipogenesis (eg, triglyceride accumulation and/or preadipocyte proliferation). These effects appeared to be mediated in part through estrogen receptor signaling, particularly for the contraceptive mixtures, as cotreatment with fulvestrant acted to inhibit contraceptive-mediated proadipogenic effects on triglyceride accumulation. In conclusion, this research provides valuable insights into the complex interactions between hormonal contraceptives and adipocyte development. The results suggest that both progestins and estrogens within these contraceptives can influence adipogenesis, and the specific effects may vary based on the receptor disruption profiles. Further research is warranted to establish translation of these findings to in vivo models and to further assess causal mechanisms underlying these effects.

RESUMEN

Many women experience sexual side effects, such as decreased libido, when taking hormonal contraceptives (HCs). However, little is known about the extent to which libido recovers after discontinuing HCs, nor about the timeframe in which recovery is expected to occur. Given that HCs suppress the activities of multiple endogenous hormones that regulate both the ovulatory cycle and women's sexual function, resumption of cycles should predict libido recovery. Here, using a combination of repeated and retrospective measures, we examined changes in sexual desire and partner attraction (among partnered women) across a three-month period in a sample of Natural Cycles users (Survey 1: n = 1596; Survey 2: n = 550) who recently discontinued HCs. We also tested whether changes in these outcomes coincided with resumption of the ovulatory cycle and whether they were associated with additional factors related to HC use (e.g., duration of HC use) or relationship characteristics (e.g., relationship length). Results revealed that both sexual desire and partner attraction, on average, increased across three months after beginning to use Natural Cycles. While the prediction that changes in sexual desire would co-occur with cycle resumption was supported, there was also evidence that libido continued to increase even after cycles resumed. Together, these results offer new insights into relationships between HC discontinuation and women's sexual psychology and lay the groundwork for future research exploring the mechanisms underlying these effects.

RESUMEN

BACKGROUND: Information on social media may affect peoples' contraceptive decision making. We performed an exploratory analysis of contraceptive content on Twitter (recently renamed X), a popular social media platform. METHODS: We selected a random subset of 1% of publicly available, English-language tweets related to reversible, prescription contraceptive methods posted between January 2014 and December 2019. We oversampled tweets for the contraceptive patch to ensure at least 200 tweets per method. To create the codebook, we identified common themes specific to tweet content topics, tweet sources, and tweets soliciting information or providing advice. All posts were coded by two team members, and differences were adjudicated by a third reviewer. Descriptive analyses were reported with accompanying qualitative findings. RESULTS: During the study period, 457,369 tweets about reversible contraceptive methods were published, with a random sample of 4,434 tweets used for final analysis. Tweets most frequently discussed contraceptive method decision-making (26.7%) and side effects (20.5%), particularly for long-acting reversible contraceptive methods and the depot medroxyprogesterone acetate shot. Tweets about logistics of use or adherence were common for short-acting reversible contraceptives. Tweets were frequently posted by contraceptive consumers (50.6%). A small proportion of tweets explicitly requested information (6.2%) or provided advice (4.2%). CONCLUSIONS: Clinicians should be aware that individuals are exposed to information through Twitter that may affect contraceptive perceptions and decision making, particularly regarding long-acting reversible contraceptives. Social media is a valuable source for studying contraceptive beliefs missing in traditional health research and may be used by professionals to disseminate accurate contraceptive information.

RESUMEN

STUDY OBJECTIVE: There are many videos on contraception on YouTube and TikTok, and women around the world use video platforms extensively to seek health information from videos of uncertain reliability and quality. The main objective of this research was to evaluate the scientific reliability and quality of the most popular social media videos about contraceptive subdermal implants. METHODS: TikTok and YouTube videos were assessed separately by two gynecologists. The video quality was evaluated according to the DISCERN score, modified DISCERN score, and Global Quality Scale (GQS) score. RESULTS: The study included the 100 most popular videos, 44 of which were uploaded by health care professionals. The median DISCERN score for videos shared by health care professionals was 50 (range 15-75), whereas it was 22 (range 15-56) for videos shared by independent users (P < .001). The median modified DISCERN score was 4 (min-max 0-5), and the median GQS score was 4 (min-max 1-5) for the videos uploaded by health care professionals. The modified DISCERN and GQS scores of TikTok videos were lower than those of YouTube videos (both P < .001). CONCLUSION: Social media videos about contraceptive subdermal implants are popular and have been viewed tens of thousands of times, but the overall medical validity, which we evaluated according to the scoring systems, was poor. Despite the large number of videos, the content's quality and reliability are quite limited. There is a need to prioritize the education provided to patients by gynecologists, as well as to create high-quality content for YouTube and other similar platforms.
