Effect of scanning duration and sample size on reliability in resting state fMRI dynamic causal modeling analysis.

Despite its widespread use, resting-state functional magnetic resonance imaging (rsfMRI) has been criticized for low test-retest reliability. To improve reliability, researchers have recommended using extended scanning durations, increased sample size, and advanced brain connectivity techniques. However, longer scanning runs and larger sample sizes may come with practical challenges and burdens, especially in rare populations. Here we tested if an advanced brain connectivity technique, dynamic causal modeling (DCM), can improve reliability of fMRI effective connectivity (EC) metrics to acceptable levels without extremely long run durations or extremely large samples. Specifically, we employed DCM for EC analysis on rsfMRI data from the Human Connectome Project. To avoid bias, we assessed four distinct DCMs and gradually increased sample sizes in a randomized manner across ten permutations. We employed pseudo true positive and pseudo false positive rates to assess the efficacy of shorter run durations (3.6, 7.2, 10.8, 14.4 min) in replicating the outcomes of the longest scanning duration (28.8 min) when the sample size was fixed at the largest (n = 160 subjects). Similarly, we assessed the efficacy of smaller sample sizes (n = 10, 20, …, 150 subjects) in replicating the outcomes of the largest sample (n = 160 subjects) when the scanning duration was fixed at the longest (28.8 min). Our results revealed that the pseudo false positive rate was below 0.05 for all the analyses. After the scanning duration reached 10.8 min, which yielded a pseudo true positive rate of 92%, further extensions in run time showed no improvements in pseudo true positive rate. Expanding the sample size led to enhanced pseudo true positive rate outcomes, with a plateau at n = 70 subjects for the targeted top one-half of the largest ECs in the reference sample, regardless of whether the longest run duration (28.8 min) or the viable run duration (10.8 min) was employed. Encouragingly, smaller sample sizes exhibited pseudo true positive rates of approximately 80% for n = 20, and 90% for n = 40 subjects. These data suggest that advanced DCM analysis may be a viable option to attain reliable metrics of EC when larger sample sizes or run times are not feasible.

Racial and Ethnic Inequities in Buprenorphine and Methadone Utilization Among Reproductive-Age Women with Opioid Use Disorder: an Analysis of Multi-state Medicaid Claims in the USA.

BACKGROUND: Associations between race/ethnicity and medications to treat OUD (MOUD), buprenorphine and methadone, in reproductive-age women have not been thoroughly studied in multi-state samples. OBJECTIVE: To evaluate racial/ethnic variation in buprenorphine and methadone receipt and retention in a multi-state U.S. sample of Medicaid-enrolled, reproductive-age women with opioid use disorder (OUD) at the beginning of OUD treatment. DESIGN: Retrospective cohort study. SUBJECTS: Reproductive-age (18-45 years) women with OUD, in the Merative™ MarketScan® Multi-State Medicaid Database (2011-2016). MAIN MEASURES: Differences by race/ethnicity (non-Hispanic White, non-Hispanic Black, Hispanic, "other" race/ethnicity) in the likelihood of receiving buprenorphine and methadone during the start of OUD treatment (yes/no) were estimated using multivariable logistic regression. Differences in time to medication discontinuation (days) by race/ethnicity were evaluated using multivariable Cox regression. RESULTS: Of 66,550 reproductive-age Medicaid enrollees with OUD (84.1% non-Hispanic White, 5.9% non-Hispanic Black, 1.0% Hispanic, 5.3% "other"), 15,313 (23.0%) received buprenorphine and 6290 (9.5%) methadone. Non-Hispanic Black enrollees were less likely to receive buprenorphine (adjusted odds ratio, aOR = 0.76 [0.68-0.84]) and more likely to be referred to methadone clinics (aOR = 1.78 [1.60-2.00]) compared to non-Hispanic White participants. Across both buprenorphine and methadone in unadjusted analyses, the median discontinuation time for non-Hispanic Black enrollees was 123 days compared to 132 days and 141 days for non-Hispanic White and Hispanic enrollees respectively (χ2 = 10.6; P = .01). In adjusted analyses, non-Hispanic Black enrollees experienced greater discontinuation for buprenorphine and methadone (adjusted hazard ratio, aHR = 1.16 [1.08-1.24] and aHR = 1.16 [1.07-1.30] respectively) compared to non-Hispanic White peers. We did not observe differences in buprenorphine or methadone receipt or retention for Hispanic enrollees compared to the non-Hispanic White enrollees. CONCLUSIONS: Our data illustrate inequities between non-Hispanic Black and non-Hispanic White Medicaid enrollees with regard to buprenorphine and methadone utilization in the USA, consistent with literature on the racialized origins of methadone and buprenorphine treatment.

Female physician infertility: the lack of adequate insurance coverage.

There is a recent decrease in fertility rates among the general population in the United States. Female physicians, who are seeking assisted reproductive technology at growing rates often because of delayed childbearing while completing medical training, are included in this statistic. With more than 340,000 practicing female physicians within the United States, female physician infertility is especially relevant. However, despite the increasing number of female physicians seeking assisted reproductive technology, there is a lack of access to adequate insurance coverage for this higher-risk patient subset. This commentary reviewed the importance of increasing infertility rates among female physicians, the associated economic burden, limited insurance coverage, and disparities in access to infertility insurance coverage. Recent studies suggest that up to 25% of female physicians are seeking assisted reproductive technology. Currently, 1 cycle of assisted reproductive technology, or egg retrieval, is estimated at approximately $19,000, with many people needing multiple cycles. Many top academic institutions do not offer enough infertility benefits to cover 1 egg retrieval cycle and the often prerequisite, less invasive procedures. Among those seeking oocyte or embryo cryopreservation for elective fertility preservation, few institutions offer coverage. Addressing and highlighting limited and variable institutional infertility coverage are crucial to gaining equal and accessible reproductive care for female physicians.

Effect of accessibility of a genetic counselor on uptake of preimplantation genetic testing for aneuploidy (PGT-A) and carrier screening for patients undergoing in vitro fertilization.

This retrospective cohort study assessed the accessibility of a genetic counselor on uptake of preimplantation genetic testing for aneuploidy (PGT-A) and carrier screening in a single academic Reproductive Endocrinology and Infertility (REI) clinic. A total of 420 patients were evaluated with 219 patients counseled by a REI physician only and 201 patients after the addition of a genetic counselor (GC) to the REI clinic team. Cycles initiated before hiring of a GC (pre-GC) were assessed from June 2018 to December 2018 and after integration of a GC (post-GC) from March 2019 to August 2019. Additionally, information regarding carrier screening was collected if available in the medical record. Results showed more patients utilized PGT-A post-GC (9.5% vs. 5.5%), although the difference between groups did not reach statistical significance (p = 0.12). Individuals who were screened post-GC or who started screening pre-GC and continued screening post-GC were screened for a larger number of conditions than if they were only screened pre-GC (median pre-GC = 3, post-GC = 27, pre- and post-GC = 274; p < 0.0001). The change in practice from using physician-only counseling to counseling with accessibility to a GC did not change the utilization of PGT-A in a single clinic.

A Comparison of Sex-Specific Reproductive and Sexual Health Needs between Addiction Medicine and Primary Care Treatment Settings.

Introduction: Reproductive and sexual health (RSH) is an important component of wellness and recovery for people with substance use disorder (SUD). Evidence to guide better integration of RSH services into SUD treatment is limited. Our objectives were to compare 1) unmet RSH needs; and 2) barriers to RSH service utilization between care settings providing treatment for SUD or other chronic medical conditions. Methods: Participants at two outpatient clinics, addiction medicine (women n = 91, men n = 75) and primary care (women n = 59, men n = 50), completed a one-time electronic survey between July and September 2019. Separately for men and women, comparisons between addiction medicine and primary care groups were made using Pearson χ2, Fisher's Exact, and T-tests. Results: Participants were 75.0% Black and aged 49.4 years. Overall, unmet RSH needs were less prevalent among participants at the primary care than the addiction medicine clinic, such as receipt of a past 12-month sexual exam (men: 36.0% vs. 17.3%; women: 55.6% vs. 30.1%). The most common barrier to RSH service receipt was cost (men: 59.4%; women: 52.6%), followed by fear of judgment for drug/alcohol use for SUD participants (men: 33% vs. 12%; women: 26% vs. 7%). Many SUD participants expressed high desire for integrated RSH services into the addiction medicine clinic (men: 51.4%; women: 59.8%). Conclusion/Implications: The integration of RSH into addiction medicine is lagging compared to care settings for people with other chronic medical conditions. Future research should focus on advancing sex- and gender-informed RSH service integration into SUD treatment settings.

Postpartum and addiction recovery of women in opioid use disorder treatment: A qualitative study.

Background: Postpartum is a highly vulnerable time for women with opioid use disorder (OUD). Our primary objective was to identify patient and provider reported aspects of the pregnancy to postpartum transition that impact recovery progress for postpartum women receiving medication for opioid use disorder (MOUD). Methods: This qualitative study consisted of semi-structured interviews with postpartum women in OUD treatment (n = 12) and providers (n = 9) at an outpatient addiction clinic. Interviews were transcribed and analyzed using an editing style approach to report themes and quotes. Results: Patients and providers identified different themes that both promote and challenge recovery during the postpartum transition. These comprised of clinical factors, including MOUD, neonatal opioid withdrawal syndrome (NOWS) and pain associated with labor and delivery as well as psychosocial factors, such as role of a support system, mental health aspects of anxiety and depression causing mood changes, stigma and mistrust among healthcare providers and child welfare. Conclusions: Patients receiving MOUD and their providers identified multiple aspects unique to the postpartum transition that substantially strengthen and/or oppose OUD recovery. These aspects impacting recovery include factors specific to the receipt of MOUD treatment and those not specific to MOUD, yet tied to the postpartum state. Overall, these findings provide insight into areas for future research focused on identifying opportunities to promote recovery-oriented care for families affected by OUD.

Addiction treatment in the postpartum period: an opportunity for evidence-based personalized medicine.

Substance use disorders (SUD) are becoming rapidly more prevalent in women and a leading cause of pregnancy associated deaths, with most deaths occurring during the 12 months after pregnancy. The postpartum period can be quite intense, especially for women seeking addiction recovery. There is a call to reconceptualize the obstetrical postpartum care model into one that extends specialised care and is tailored to an individual's specific needs. Although SUD treatment improves maternal and infant outcomes as well as decreases overdose risk, many women do not receive consistent SUD treatment during the postpartum period. Thus, SUD treatments should consider following the same guidance as obstetrics to reconceptualize how SUD treatment is delivered postpartum. Clinically, this translates into substantially modifying traditional siloed SUD treatment structures to meet the unique needs of this vulnerable patient population. At the same time, more research is urgently needed to inform these advancements in clinical care to ensure they are evidence-based and effective. In this article, we review the existing evidence as well as highlight opportunities for both clinicians and researchers to advance the integration of tailored approaches for postpartum women into personalised SUD medical and behavioural treatments.

Pregnancy and Fertility Concerns: A Survey of United States Obstetrics and Gynecology Residents.

INTRODUCTION: Reproductive life planning is an important aspect of OBGYN resident education. Despite learning about declining fertility and the implications associated with delaying pregnancy, OBGYN residents overestimate the age when fertility declines and fertility treatment success rates. OBJECTIVE: To characterize attitudes towards infertility, pregnancy timing, and fertility preservation among OBGYN residents at academic programs in the United States. METHODS: Cross sectional study of female trainees from 27 academic OBGYN residency programs. A voluntary, anonymous online survey was used to assess reproductive experiences and characterize attitudes towards personal family planning and infertility. RESULTS: Of 756 trainees who were sent the survey, 487 opened the email, and 309 participated (63.4% response rate per opened email, 40.9% overall). The majority of residents expressed a desire to have children, but had not started childbearing (75.8%, n = 210) with a planned delay for career/educational reasons (84.5%, n = 196). The majority planned to have children before age 35 (90%, n = 210). Of those not finished with childbearing, 78.5% reported worrying about infertility (n = 205) and 40.8% reported considering fertility preservation (n = 111). If interested in fellowship, trainees were more worried about infertility (p = 0.01, OR 2.74 (95% CI 1.24 -6.04)). CONCLUSIONS FOR PRACTICE: Female OBGYN residents learn to help patients with reproductive planning and many may personally delay family building. To help alleviate anxiety, improve reproductive autonomy, and prevent future regret, OBGYN residents may benefit from counseling regarding declining fertility with age and the advantages and disadvantages of fertility preservation, specifically emphasizing the realistic chance of success with oocyte cryopreservation compared to conception at a young age.

Recovery capital among people receiving treatment for opioid use disorder with buprenorphine.

BACKGROUND: Recovery is a multidimensional process that includes health, quality of life, and citizenship. Recovery capital is a strengths-based concept representing the sum of an individual's resources that support recovery. This study (1) describes recovery capital, (2) examines the relationship between recovery capital and treatment duration, and (3) assesses differences by gender in recovery capital among people receiving medication for opioid use disorder (MOUD). METHODS: This is a secondary data analysis of a cross-sectional study, with survey and medical record review components, conducted with patients recruited from an office-based opioid treatment clinic between July and September 2019. Analyses included participants receiving MOUD with buprenorphine who completed the Brief Assessment of Recovery Capital (BARC-10; n = 130). Univariate analyses explored differences by gender. Multivariate linear regression assessed the relationship between BARC-10 total score and length of current treatment episode. RESULTS: Participants were 54.6% women and 67.4% Black with mean age of 42.4 years (SD = 12.3). Mean length of current MOUD treatment was 396.1 days (SD = 245.9). Total BARC-10 scores were high, but participants perceived low community-level resources. Women scored higher than men within the health and purpose recovery dimensions. While length of treatment was not associated with BARC-10 score, experiencing recent discrimination was associated with a significantly lower BARC-10 score. CONCLUSIONS: Recovery capital among individuals receiving MOUD was high suggesting that participants have resources to support recovery, but gender differences and prevalent discrimination highlight areas for improved intervention. More work is needed to investigate recovery capital as an alternative treatment outcome to abstinence in outpatient MOUD populations.

Computational Optimization Study of Transcatheter Aortic Valve Leaflet Design Using Porcine and Bovine Leaflets.

In this study, a Bayesian optimization (BO) based computational framework is developed to investigate the design of transcatheter aortic valve (TAV) leaflets and to optimize leaflet geometry such that its peak stress under the blood pressure of 120 mmHg is reduced. A generic TAV model is parametrized by mathematical equations describing its 2D shape and its 3D stent-leaflet assembly line. Material properties previously obtained for bovine pericardium (BP) and porcine pericardium (PP) via a combination of flexural and biaxial tensile testing were incorporated into the finite element (FE) model of TAV. A BO approach was employed to investigate about 1000 leaflet designs for each material under the nominal circular deployment and physiological loading conditions. The optimal parameter values of the TAV model were obtained, corresponding to leaflet shapes that can reduce the peak stress by 16.7% in BP and 18.0% in PP, compared with that from the initial generic TAV model. Furthermore, it was observed that while peak stresses tend to concentrate near the stent-leaflet attachment edge, optimized geometries benefit from more uniform stress distributions in the leaflet circumferential direction. Our analysis also showed that increasing leaflet contact area redistributes peak stresses to the belly region contributing to peak stress reduction. The results from this study may inspire new TAV designs that can have better durability.

Addiction and Depression: Unmet Treatment Needs Among Reproductive Age Women.

OBJECTIVES: To describe the current unmet major depression and substance use disorder (SUD) treatment needs among reproductive age women METHODS: Data from the 2007 to 2014 National Survey on Drug Use and Health (NSDUH) were analyzed to determine proportions of women ages 18 to 44 years with unmet treatment need for depression and SUD. Logistic regression determined factors associated with receiving past year SUD and major depression treatment among those in need. RESULTS: Only 9.2% of women with past year SUD treatment need received treatment (95% CI 8.3-10.1%) compared to 60.7% for those in need of depression treatment (95% CI 59.5-62.0%). Over time, treatment receipt for depression increased significantly (OR 1.4, 95% CI 1.15-1.67) but not for substance use disorders (OR 1.4, 95% CI 0.69-1.45). Neither pregnant nor parenting women were more likely to receive treatment for SUD or depression. Young and racial/ethnically minority women were less likely to receive needed behavioral health treatment for either condition. CONCLUSIONS: Depression and SUD treatment need are common among women. However, treatment receipt differs between these behavioral health conditions.

Fertility, Pregnancy, and Postpartum: A Survey of Practicing Georgia Obstetrician Gynecologists.

PURPOSE: OBGYNs help patients plan families, conceive, and deliver children, however the personal reproductive history and goals, infertility experiences, and birth outcomes of OBGYNs are not well studied. We aim to characterize female OBGYN reproductive experiences with a particular focus on infertility, reproductive life planning (methods of pregnancy prevention, reasons why pregnancy is/was delayed), birth outcomes (mode of delivery, delivery timing), and the postpartum period (breastfeeding, maternity leave, postpartum depression). DESCRIPTION: An anonymous email survey was distributed to female members of Georgia OBGYN Society and Emory University Department of Gynecology and Obstetrics. Descriptive statistics and bivariable analysis were performed using Microsoft Excel and OpenEpi. ASSESSMENT: Of 352 surveys, 204 of 269 women who opened the survey agreed to participate (75.8% per opened email, 58.0% per sent email). Mean age of first childbirth was 30.7 (SD ± 4.2) years. Most pregnancies were intended (77%). Fertility treatments were used in 13% of pregnancies. Resident mothers compared to mothers who gave birth before or after residency were more likely to report postpartum depression [26% vs. 16%, OR 1.8 (95% CI 0.93-3.58)] and shorter maternity leave < 6 weeks [57% vs. 29%, OR 2.57 (CI 1.56-5.00)]; exclusive breastfeeding rates ≥ 6 months were similar [38% residents vs. 41% non-residents, OR 0.80 (CI 0.44-1.43)]. Among those not finished with childbearing, 68% worried about infertility, 29% were considering oocyte/embryo cryopreservation, and 5% had already cryopreserved oocytes. CONCLUSION: Compared to the general population, the average age of first childbirth among Georgia OBGYNs was 4 years higher (30.7) with a greater proportion of pregnancies planned. Use of fertility services and obstetric course matched national rates, however postpartum depression was more prevalent among Georgia OBGYNs. Awareness of increased postpartum depression among residents may allow for improved counseling and treatment.

Pregnancy intention and opioid use disorder treatment retention in the MOTHER study.

BACKGROUND AND OBJECTIVES: Opioid use disorder (OUD) during pregnancy challenges public health. This study examines how pregnancy intention affects OUD treatment. METHODS: The primary exposure and outcome were pregnancy intention and treatment duration among MOTHER (Maternal Opioid Treatment: Human Experimental Research) participants (N = 175). RESULTS: Treatment durations were longer (21.3 vs. 16.3 weeks; p = .01) among intended (n = 29) compared to unintended (n = 146) pregnancy participants, but this was not significant in adjusted analyses. DISCUSSION AND CONCLUSIONS: Unintended pregnancies intersect with OUD and may modify one's treatment outcomes. SCIENTIFIC SIGNIFICANCE: OUD treatment may be a setting to help women implement informed family planning choices. (Am J Addict 2018;XX:1-3).

Contraceptive utilization among new exotic dancers: a cross-sectional study.

BACKGROUND: Female exotic dancers are a population at high risk of unintended pregnancy. The objective of this study is to describe the reproductive health needs and contraceptive utilization of exotic dancers. METHODS: New exotic dancers (< 6 months dancing) from 26 clubs in Baltimore City/County completed a one-time survey. RESULTS: Of 117 participants, 96 (82%) had current contraceptive need. The mean age was 24 years, and 55% were black. Sex work (45%), alcohol use disorder (73%), illicit (44%; e.g., heroin, crack, cocaine), and injection drug use (8%) were common. The majority (66%) reported contraception use in the prior 6 months. Condoms were reported by 46% whereas 45% reported non-barrier methods, most commonly hormonal injection. Consistent condom use was rare (3%), and only 11% used a long-acting reversible method. CONCLUSIONS: Despite their unique reproductive health vulnerabilities, female exotic dancers have unmet contraceptive needs. Targeted harm reduction strategies are needed to fill this gap.

Factors predicting double embryo implantation following double embryo transfer in assisted reproductive technology: implications for elective single embryo transfer.

PURPOSE: The aim of this study was to identify factors associated with double embryo implantation following double embryo transfer (DET) during assisted reproductive technology (ART) procedures and to evaluate the implications of findings in selecting candidates for elective single embryo transfer (eSET). METHODS: Factors predicting double embryo implantation, defined as embryo transfers with two or more heartbeats on 6-week ultrasound following DET, were assessed using the US National ART Surveillance System data from 2000 to 2012 (n = 1,793,067 fresh, autologous transfers). Adjusted risk ratios (aRRs) were estimated after stratifying by prognosis. Favorable prognosis was defined as first-time ART with supernumerary embryo(s) cryopreserved. Average prognosis was defined as first-time ART without supernumerary embryo(s) cryopreserved, prior unsuccessful ART with supernumerary embryo(s) cryopreserved, or prior ART with previous birth(s) conceived with ART or naturally. Rates and factors associated with double embryo implantation were compared with single embryo implantation following DET among both prognosis groups. RESULTS: Double embryo implantation was positively associated with blastocyst (versus cleavage) transfer in favorable (aRR = 1.58 (1.51-1.65)) and average (aRR = 1.67 (1.60-1.75)) prognosis groups and negatively associated with age >35 years in both prognosis groups. For average prognosis patients, double embryo implantation was associated with retrieving >10 oocytes (aRR = 1.22 (1.18-1.24)). CONCLUSIONS: Regardless of prognosis, patients aged <35 years with blastocyst-stage embryos and average prognosis patients from whom >10 oocytes were retrieved may be good candidates for eSET. Physicians may consider using these data to counsel patients on eSET, which would reduce multiple gestations and associated complications.

Patient-specific finite element analysis of ascending aorta aneurysms.

Catastrophic ascending aorta aneurysm (AsAA) dissection and rupture can be prevented by elective surgical repair, but identifying individuals at risk remains a challenge. Typically the decision to operate is based primarily on the overall aneurysm size, which may not be a reliable indicator of risk. In this study, AsAA inflation and rupture was simulated in 27 patient-specific finite element models constructed from clinical CT imaging data and tissue mechanical testing data from matching patients. These patients included n = 8 with concomitant bicuspid aortic valve (BAV), n = 10 with bovine aortic arch (BAA), and n = 10 with neither BAV nor BAA. AsAA rupture risk was found to increase with elevated systolic wall stress and tissue stiffness. The aortic size index was sufficient for identifying the patients with the lowest risk of rupture, but unsuitable for delineating between patients at moderate and high risk. There was no correlation between BAV or BAA and AsAA rupture risk; however, the AsAA morphology was different among these patients. These results support the use of mechanical parameters such as vessel wall stress and tissue stiffness for AsAA presurgical evaluation.

Computational modeling of cardiac valve function and intervention.

In the past two decades, major advances have been made in the clinical evaluation and treatment of valvular heart disease owing to the advent of noninvasive cardiac imaging modalities. In clinical practice, valvular disease evaluation is typically performed on two-dimensional (2D) images, even though most imaging modalities offer three-dimensional (3D) volumetric, time-resolved data. Such 3D data offer researchers the possibility to reconstruct the 3D geometry of heart valves at a patient-specific level. When these data are integrated with computational models, native heart valve biomechanical function can be investigated, and preoperative planning tools can be developed. In this review, we outline the advances in valve geometry reconstruction, tissue property modeling, and loading and boundary definitions for the purpose of realistic computational structural analysis of cardiac valve function and intervention.

Evaluation of a single-visit approach to cervical cancer screening and treatment in Guyana: feasibility, effectiveness and lessons learned.

AIM: To evaluate a cervical cancer prevention project in Guyana utilizing visual inspection with acetic acid (VIA) and immediate cryotherapy in a single-visit approach; and to identify lessons learned to inform the improvement of cervical cancer prevention programs in Guyana and other low-resource settings. METHODS: Service records from January 2009 to June 2012 were analyzed for 18 cervical cancer prevention sites across Guyana. Records included women's HIV status, data on visual inspection with acetic acid screening and treatment status for women's initial and 1-year follow-up screenings, provider training and retention. A process evaluation was conducted in 2011 to identify programmatic strengths and interventions for integration, scale-up and sustainability. RESULTS: During the 42-month interval, 21,597 new screenings were performed, reaching 95% of HIV(+) women enrolled in care and 17% of women aged 25-49 years in Guyana. The VIA(+) rate was 13% (n = 2806); 85% of women eligible for cryotherapy received immediate treatment. Half of VIA(+) women treated with cryotherapy or loop electrosurgical excision procedure returned for a 1-year follow-up screening (n = 1027); 95% were VIA(-) at the second screening. Non-physician providers were more likely to continue offering services than physicians. Most programmatic challenges were related to systemic rather than technical/clinical issues. CONCLUSION: The single-visit approach-based program is feasible, effective, and when scaled up, likely to have an impact on overall incidence of cervical cancer. Services can be shifted to non-physicians for scale-up of high-quality cervical cancer prevention services nationally. To ensure sustainability and expansion, support structures should be prioritized.

Low-dose buprenorphine initiation during pregnancy: a case report.

Buprenorphine is recommended for pregnant patients with opioid use disorder. Traditional buprenorphine initiation requires moderate withdrawal symptoms to prevent precipitating withdrawal. Low-dose buprenorphine initiation is newly emerging and does not require withdrawal prior to initiation. Case 1 is a 30-year-old pregnant patient with opioid use disorder. Inpatient rapid buprenorphine initiation precipitated withdrawal. Low-dose buprenorphine initiation was started twice, 1 outpatient and 1 inpatient with nonprescribed opioid use between. Case 2 is a 28-year-old pregnant patient with opioid use disorder. The patient started an inpatient low-dose buprenorphine initiation and planned its completion at home after discharge. Neither patient experienced precipitated withdrawal during their low-dose initiations. These buprenorphine initiations in pregnant patients guided by a low-dose initiations protocol using only split buprenorphine-naloxone films represent an alternative opioid use disorder treatment method with potentially high acceptability. Future work is warranted to advance the evidence base informing clinicians on how to optimally individualize buprenorphine initiations in pregnancy.
