RESUMEN

INTRODUCTION: Oral pre-exposure prophylaxis (PrEP) is a highly effective HIV prevention method; however, uptake and persistence have been low among southern African women. A dual prevention pill (DPP) that combines PrEP with oral contraception (OC) may increase PrEP use and better meet women's sexual and reproductive health needs. We will gauge the DPP's acceptability in two cross-over clinical trials. METHODS AND ANALYSIS: PC952 (Zimbabwe) and PC953 (South Africa) will compare acceptability, adherence and preference for an over-encapsulated DPP versus PrEP and OCs taken separately. HIV-negative, non-pregnant cisgender females in Johannesburg, South Africa (n=96, 16-40 years) and Harare, Zimbabwe (n=30, 16-24 years) will be randomised 1:1 to the order of regimens-DPP or two separate tablets-each used for three 28-day cycles, followed by a 6-month choice period in South Africa. Monthly clinic visits include HIV and pregnancy testing; safety assessments and risk reduction and adherence counselling. We will assess adherence (monthly) based on tenofovir diphosphate drug levels in dried blood spots and by self-report. We will evaluate acceptability (monthly) and preference (end of cross-over) via computer-assisted self-interviewing and in-depth interviews with a subset of participants. Data collection started in September 2022 and ended in January 2024. ETHICS AND DISSEMINATION: PC952 was approved by the Ministry of Health and Child Care, Medical Research Council, Research Council and Medicines Control Authority of Zimbabwe; the Chitungwiza City Health Ethics Committee; and the Joint Research Ethics Committee for the University of Zimbabwe Faculty of Medicine and Health Sciences and Parirenyatwa Group of Hospitals. PC953 was approved by the South African Health Products Regulatory Authority and the University of the Witwatersrand's Human Research Ethics Committee. The Population Council IRB approved both studies. We will disseminate results in open-access journals, clinical trials registries, and at local and international meetings and conferences. TRIAL REGISTRATION NUMBERS: NCT04778514, NCT04778527.

RESUMEN

BACKGROUND: Current guidance on the selection of appropriate contraception for people with multiple sclerosis (PwMS) is lacking. OBJECTIVE: To address this gap, an expert-led consensus program developed recommendations to support clinicians in discussing family planning and contraception with women and men with multiple sclerosis (MS). METHODS: A multidisciplinary steering committee (SC) of 13 international clinical experts led the program, supported by an extended faculty of 32 experts representing 18 countries. A modified Delphi methodology was used for decision-making and consensus-building. The SC drafted 15 clinical questions focused on patient-centered care, selection of contraception, and timing of stopping/starting contraception and disease-modifying therapies (DMTs). Statements addressing each question were drafted based on evaluation of published evidence and the experts' clinical experience. Consensus was reached if ⩾75% of respondents agreed (scoring 7-9 on a 9-point scale) with each recommendation. RESULTS: Consensus was reached on 24 of 25 proposed recommendations, including how and when to discuss contraception, types and safety of contraceptives, and how to evaluate the most appropriate contraceptive options for specific patient groups, including those with significant disability or being treated with DMTs. CONCLUSION: These expert recommendations provide the first practical, relevant, and comprehensive guidance for clinicians on the selection of contraception in PwMS.

RESUMEN

BACKGROUND: The US Food and Drug Administration-approved segesterone acetate and ethinyl estradiol ring-shaped contraceptive vaginal system, known as Annovera (Sever Pharma Solutions/QPharma, Malmö, Sweden), was inserted and removed under a woman's control for a 21 day in and 7 day out regimen for up to 13 cycles of use. OBJECTIVE: We aimed to describe the patterns of ring expulsion over time, to identify potential predictors of expulsion, and to evaluate the impact of expulsions on method discontinuation and pregnancy risk. STUDY DESIGN: Using data from 2064 participants who were enrolled in 2 multinational phase 3 clinical trials on the use of this contraceptive vaginal system, we examined data from participants' daily diaries for documentation of complete ring expulsion. We modeled the odds of reported expulsions over time with adjustment for background and demographic characteristics using mixed-effects logistic regression models with random intercepts. We compared the probability of continuation between those who did and those who did not report expulsions in the first cycle of use using survival analysis and hazards modeling. To determine if expulsions during the first cycle of use affected the risk for pregnancy, we calculated Pearl Indices. RESULTS: Most participants (75%) never experienced any expulsions during any cycle of use, and 91% to 97% did not experience an expulsion during any 1 cycle. The incidence of expulsion was highest in cycle 1 (9%). The odds of experiencing expulsions decreased by half in cycles 2 to 8 when compared with cycle 1 (0.48; 95% confidence interval, 0.40-0.58), and in cycles 9 to 13, expulsions were about a third of that in cycle 1 (0.32; 95% confidence interval, 0.26-0.41). Of those who did experience expulsions, most (62%-84%) experienced ≤2 expulsions per cycle. Participants from study sites in Latin America vs those in the United States had higher odds of not experiencing an expulsion (odds ratio, 1.95; 95% confidence interval, 1.45-2.63). Women with a higher education level had higher odds of experiencing an expulsion. Notably, parity, age, and body mass index were not associated with expulsion. Participants who experienced any expulsions in cycle 1 were more likely to discontinue use early (hazard ratio, 1.28; 95% confidence interval, 1.14-1.43) than participants who did not have an expulsion. The Pearl Index for participants who had expulsions during cycle 1 was 3.99 (95% confidence interval, 1.29-9.31), which was higher than that among participants who reported no expulsions (Pearl Index, 2.39; 95% confidence interval, 1.61-3.41), but the overlapping confidence intervals indicate that there is not sufficient evidence to demonstrate an association between expulsions and pregnancy risk. CONCLUSION: Expulsions were infrequent overall, decreased with subsequent cycles of use, and were not associated with body mass index or parity. Early discontinuation of product use was higher among participants who experienced an expulsion during cycle 1. Although it is unclear whether pregnancy risk was associated with expulsions, early recognition of expulsions among users may identify those at higher risk for discontinuation and may highlight when enhanced anticipatory counselling and guidance may be advantageous.

RESUMEN

Despite their importance for immunity against sexually transmitted infections, the composition of female reproductive tract (FRT) memory T-cell populations in response to changes within the local tissue environment under the regulation of the menstrual cycle remains poorly defined. Here, we show that in humans and pig-tailed macaques, the cycle determines distinct clusters of differentiation 4 T-cell surveillance behaviors by subsets corresponding to migratory memory (TMM) and resident memory T cells. TMM displays tissue-itinerant trafficking characteristics, restricted distribution within the FRT microenvironment, and distinct effector responses to infection. Gene pathway analysis by RNA sequencing identified TMM-specific enrichment of genes involved in hormonal regulation and inflammatory responses. FRT T-cell subset fluctuations were discovered that synchronized to cycle-driven CCR5 signaling. Notably, oral administration of a CCR5 antagonist drug blocked TMM trafficking. Taken together, this study provides novel insights into the dynamic nature of FRT memory CD4 T cells and identifies the menstrual cycle as a key regulator of immune surveillance at the site of STI pathogen exposure.

RESUMEN

Objectives: Employee work engagement, job satisfaction, quality of care, and intent to leave are critical indicators for healthcare organizational performance. This study aimed to analyze the current state of nurses' work engagement and its factors to examine the associations among nurses' work engagement, job satisfaction, quality of care, and intent to leave in the United States (US). Methods: This is a quantitative descriptive cross-section design. Data were collected online from the US registered nurses from March to September 2022. Measures comprised the Utrecht Work Engagement Scale, the demographics, and questions regarding job satisfaction, perceived quality of care, and intent to leave. Results: Nine hundred nurses participated in the online survey. Among the participants, 79.2% reported holding a specialty certification, 59.4% scored high/very high on job satisfaction, 82.2% expressed high/very high on the perceived quality of nursing care, and 28.4% conveyed likely/very likely to leave in the following year. Nurses' work engagement was positively associated with nurses' job satisfaction and their perceived quality of care but negatively associated with intent to leave. More certified nurses reported high or very high job satisfaction than non-certified nurses. As for demographics, the linear regression analysis showed that nurses who were older, identified as White, and held doctorate degrees reported higher levels of work engagement in comparison to their counterparts. Conclusions: This study shows that nurses' work engagement is associated with their job satisfaction, perceived quality of care, and intent to leave. Nurses' work engagement in this study is lower than in other studies, especially before the COVID-19 pandemic, which may indicate a possible association with the COVID-19 impact. Because nurses' work engagement is significantly associated with job satisfaction, nurse leaders need to find ways to promote nurses' job satisfaction and retention.

RESUMEN

This study examined the relationship between cognitive preference and clinical experience in student registered nurse anesthetists (SRNAs) and certified registered nurse anesthetists (CRNAs). Survey data was collected from enrolled SRNAs and practicing CRNAs via an email link distributive through a network sampling technique. Participants completed the Rational Experiential Inventory (REI-40), which assesses individuals' preference, ability, and engagement with rational and experiential cognitive styles. Data analysis revealed that SRNAs and CRNAs have the ability and engagement preference for rational decision-making. Furthermore, there was no statistical significance in years of clinical experience to cognitive preference, nor was there a statistically significant difference between SRNA and CRNA REI-40 Inventory results. Based on these findings, the dominant cognitive preference is rational cognition and experiential thinking preference remains constant with increased experience. This knowledge contributes to our understanding of CRNAs' decision-making related to cognitive processes and provides insight into SRNA clinical education and CRNA continuing development.

RESUMEN

OBJECTIVE: The aim of this study was to understand how vaginal microbiota composition affects antiretroviral concentrations in the setting of hormonal contraception initiation. METHODS: Cervicovaginal fluid (CVF) concentrations of tenofovir, lamivudine, and efavirenz from 73 Malawian women with HIV were compared before and after initiation of depot-medroxyprogesterone acetate (DMPA) or levonorgestrel implant. We evaluated antiretroviral concentrations and vaginal microbiota composition/structure in the context of contraception initiation and predicted genital shedding using multivariable repeated measurements models fit by generalized estimating equations. RESULTS: Mean lamivudine CVF concentrations decreased 37% 1 month after contraception initiation. Subgroup analyses revealed a 41% decrease in women 1 month after initiating levonorgestrel implant, but no significant difference was observed in DMPA group alone. Tenofovir, lamivudine, and efavirenz CVF concentrations were positively correlated with anaerobic bacteria associated with nonoptimal vaginal microbiota. Risk of genital HIV shedding was not significantly associated with tenofovir or lamivudine CVF concentrations [tenofovir relative risk (RR): 0.098, P = 0.75; lamivudine RR: 0.142, P = 0.54]. Lack of association between genital HIV shedding and efavirenz CVF concentrations did not change when adjusting for vaginal microbiota composition and lamivudine/tenofovir CVF concentrations (RR: 1.33, P = 0.531). CONCLUSION: No effect of hormone initiation on genital shedding provides confidence that women with HIV on either DMPA or levonorgestrel implant contraception will not have compromised ART efficacy. The unexpected positive correlation between antiretroviral CVF concentrations and certain bacterial taxa relative abundance requires further work to understand the mechanism and clinical relevance.

RESUMEN

Introduction: The pipeline for multi-purpose prevention technologies includes products that simultaneously prevent HIV, pregnancy and/or other sexually transmitted infections. Among these, the Dual Prevention Pill (DPP) is a daily pill co-formulating oral pre-exposure prophylaxis (PrEP), and combined oral contraception (COC). Clinical cross-over acceptability studies for the DPP require training providers to counsel on a combined product. From February 2021-April 2022, a working group of eight HIV and FP experts with clinical and implementation expertise developed counseling recommendations for the DPP based on existing PrEP/COC guidance. Assessment of policy/guidelines options and implications: The working group conducted a mapping of counseling messages from COC and oral PrEP guidance and provider training materials. Six topics were prioritized: uptake, missed pills, side effects, discontinuation and switching, drug interactions and monitoring. Additional evidence and experts were consulted to answer outstanding questions and counseling recommendations for the DPP were developed. Missed pills was the topic with the most complexity, raising questions about whether women could "double up" on missed pills or skip the last week of the pack to recover protection faster. Uptake required aligning the time to reach protective levels for both DPP components and explaining the need to take DPP pills during week 4 of the pack. The potential intensity of DPP side effects, given the combination of oral PrEP with COC, was an important consideration. Discontinuation and switching looked at managing risk of HIV and unintended pregnancy when stopping or switching from the DPP. Guidance on drug interactions contended with differing contraindications for COC and PrEP. Monitoring required balancing clinical requirements with potential user burden. Actionable recommendations: The working group developed counseling recommendations for the DPP to be tested in clinical acceptability studies. Uptake: Take one pill every day for the DPP until the pack is empty. Days 1-21 contain COC and oral PrEP. Days 22-28 do not contain COC to allow for monthly bleeding, but do contain oral PrEP and pills should be taken to maintain HIV protection. Take the DPP for 7 consecutive days to reach protective levels against pregnancy and HIV. Missed pills: If you miss 1 pill multiple times in a month or 2+ consecutive pills, take the DPP as soon as you remember. Do not take more than 2 pills in a day. If 2+ consecutive pills are missed, only take the last missed pill and discard the other missed pills. Side effects: You may experience side effects when you start using the DPP, including changes to monthly bleeding. Side effects are typically mild and go away without treatment. Discontinuation/switching: If you decide to discontinue use of the DPP, but want to be protected from HIV and/or unintended pregnancy, in most cases, you can begin using PrEP or another contraceptive method right away. Drug interactions: There are no drug-drug interactions from combining oral PrEP and COC in the DPP. Certain medications are not recommended due to their contraindication with oral PrEP or COC. Monitoring: You will need to get an HIV test prior to initiating or restarting the DPP, and every 3 months during DPP use. Your provider may recommend other screening or testing. Discussion: Developing recommendations for the DPP as a novel MPT posed unique challenges, with implications for efficacy, cost, and user and provider comprehension and burden. Incorporating counseling recommendations into clinical cross-over acceptability studies allows for real-time feedback from providers and users. Supporting women with information to use the DPP correctly and confidently is critically important for eventual scale and commercialization.

RESUMEN

OBJECTIVE: The aim of this study was to examine the association of timing of antiretroviral therapy (ART) initiation and ART class with risk of new-onset hypertensive disorders of pregnancy (HDP) among people with HIV (PWH). DESIGN: An observational study of participants in the multisite Surveillance Monitoring for ART Toxicities (SMARTT) study. METHODS: Data were abstracted from medical records of pregnant PWH enrolled in SMARTT (January 30, 2015 to March 25, 2019). New-onset HDP included gestational hypertension, preeclampsia/eclampsia, or HELLP syndrome. We examined the associations of clinical risk factors and three exposures of interest, each in a separate model, with risk of new-onset HDP. Log-binomial regression models were fit using generalized estimating equations to account for correlations within people. Exposures included timing of ART initiation, antiretroviral class among those on therapy at conception, and antiretroviral class among those initiating treatment during pregnancy. RESULTS: Of 1038 pregnancies in this cohort, 973 were singletons with complete data on HDP, with ART use in 948. Overall, 9% had a new-onset HDP, 10% had chronic hypertension, and 81% had no hypertension. Diabetes [adjusted relative risk (aRR) 2.44, 95% confidence interval (95% CI) 1.42-4.21] and first/second trimester CD4 + cell count less than 200 cells/µl (aRR 1.99, 95% CI 1.21-3.27) were associated with a greater risk of new-onset HDP. Risk of new-onset HDP was similar by antiretroviral class, but those initiating ART after 20 weeks' gestation had a greater risk (aRR 1.93, 95% CI 1.12-3.30) compared with those receiving ART at conception. CONCLUSION: In this large, diverse cohort of pregnant PWH, worse early pregnancy immune status and later ART initiation were associated with an increased risk of HDP while ART class was not.

RESUMEN

Objectives: Nursing specialty certification validates nurses' mastery of specialty knowledge in disease management, education, or leadership above entry-level education and licensing. Research suggests direct relationships between nursing certifications and patient care quality. However, nurses' specialty certification rates are still low. This study aims to better understand nurses' perceptions of the facilitators and barriers in promoting nurses' desires and ability to obtain specialty certifications, which exclude advanced nursing practice roles, such as nurse practitioner or nurse midwife. Methods: This qualitative descriptive study took place virtually across the United States from May 2022 to September 2022. The study sample was a nested sample of a large national survey study. Among the nurses agreeing to be interviewed, a purposive sampling method was used to achieve maximum variation in diversity, such as years as a nurse, race, ethnicity, and certification status. Information saturation was used to gauge the sample size. Data were collected via in-depth virtual face-to-face interviews. The coding process was based on Colaizzi's method of data analysis. Results: Twenty nurses participated in the study. Five major themes emerged related to organizational culture and strategies to foster nurse specialty certifications. The five organizational strategies included 1) sharing resources, 2) a culture of ownership and a sense of belonging, 3) mentorship and role modeling, 4) recognizing nurses' efforts and accomplishments, and 5) cultivating a sense of meaning, purpose, and support. Conclusions: The findings indicate that organizational culture and leadership significantly promote continuing learning environments. Organizations need to develop an organizational culture that promotes nurses' specialty certifications. This study identified significant areas that are important to support nurses seeking certifications. Additional research is needed to evaluate which interventions significantly impact initial and continued certification levels, especially in the post-COVID-19 era.

RESUMEN

OBJECTIVE: We evaluated gestational weight gain (GWG) in pregnant persons with HIV (PWH) enrolled in the Surveillance Monitoring for ART Toxicities study. DESIGN: This was a cohort study. METHODS: GWG was classified as excessive, adequate, or inadequate; weekly GWG in second and third trimesters was calculated using National Academy of Medicine standards. Adjusted modified Poisson and linear regression models were fit with generalized estimating equations to assess the association of antiretroviral treatment (ART) with GWG outcomes stratified by timing of ART initiation [at conception (ART-C) and initiating during pregnancy (ART-I)]. RESULTS: We included 1477 pregnancies (847 ART-C, 630 ART-I) from 1282 PWH. The proportion of excessive, adequate, and inadequate GWG was 44, 24, and 32%, respectively. No associations of ART class with excessive GWG were observed overall. However, among ART-I pregnancies with overweight prepregnancy BMI-based, protease inhibitor-based, nonnucleoside reverse transcriptase inhibitor-based, and nucleoside reverse transcriptase inhibitor-based ART were associated with significantly lower GWG per week than integrase inhibitor (INSTI)-based ART [mean differences: -0.14, -0.27, and -0.29 kg/week, respectively]. Among ART-I pregnancies with obese prepregnancy BMI, lower weekly GWG was also observed for protease inhibitor-based vs. INSTI-based ART (mean difference: -0.14 kg/week). CONCLUSION: ART class type was not associated with excessive GWG. However, PWH entering pregnancy already overweight/obese and initiating INSTI-based ART had higher weekly GWG in second and third trimesters vs. other ART classes. Further studies to understand how increases in weekly GWG for overweight/obese PWH impinges on long-term maternal/child health are warranted.

RESUMEN

BACKGROUND: Little is known about inflammation/immune activation during pregnancy in people with HIV (PWH) and growth in their children who are HIV-exposed and uninfected (CHEU). METHODS: Using data from the Pediatric HIV/AIDS Cohort Study and an HIV-seronegative comparison group, we assessed associations of (1) HIV status, mode of HIV acquisition (perinatally vs nonperinatally acquired), and type of antiretroviral therapy (ART) with inflammation/immune activation in pregnancy; and (2) inflammation/immune activation in pregnancy with growth of CHEU at 12 months. Interleukin 6 (IL-6), high-sensitivity C-reactive protein (hs-CRP), soluble(s) TNF-α receptor 1 and 2 (sTNFR1, sTNFR2), sCD14, and sCD163 were measured between 13 and 27 weeks' gestation. Linear regression models were fit to estimate differences between groups for each log-transformed biomarker, adjusted for confounders. RESULTS: Pregnant PWH (188 total, 39 perinatally acquired, 149 nonperinatally acquired) and 76 HIV-seronegative persons were included. PWH had higher IL-6, sTNFR1, sCD14, and sCD163 and lower sTNFR2 compared to HIV-seronegative persons in adjusted models. Among PWH, sCD163 was higher in those with perinatally versus nonperinatally acquired HIV and on PI-based versus INSTI-based ART. Higher maternal concentrations of IL-6, sTNFR2, and hs-CRP were associated with poorer growth at 12 months. CONCLUSIONS: Maternal HIV status is associated with a distinct profile of inflammation/immune activation during pregnancy, which may influence child growth.

RESUMEN

Important questions remain on how hormonal contraceptives alter the local immune environment and the microbiota in the female genital tract and how such effects may impact susceptibility to HIV infection. We leveraged samples from a previously conducted clinical trial of Malawian women with (n = 73) and without (n = 24) HIV infection randomized to depot medroxyprogesterone acetate (DMPA) or the levonogestrel implant in equal numbers within each group and determined the effects of these hormonal contraceptives (HCs) on the vaginal immune milieu and the composition of the vaginal microbiota. Longitudinal data for soluble immune mediators, measured by multiplex bead arrays and enzyme-linked immunosorbent assays (ELISAs), and vaginal microbiota, assessed by 16S rRNA gene amplicon, were collected prior to and over a period of 180 days post-HC initiation. DMPA and levonogestrel had only minimal effects on the vaginal immune milieu and microbiota. In women with HIV, with the caveat of a small sample size, there was an association between the median log10 change in the interleukin-12 (IL-12)/IL-10 ratio in vaginal fluid at day 180 post-HC compared to baseline when these women were classified as having a community state type (CST) IV vaginal microbiota and were randomized to DMPA. Long-lasting alterations in soluble immune markers or shifts in microbiota composition were not observed. Furthermore, women with HIV did not exhibit increased viral shedding in the genital tract after HC initiation. Consistent with the results of the ECHO (Evidence for Contraceptive Options and HIV Outcomes) trial, our data imply that the progestin-based HC DMPA and levonorgestrel are associated with minimal risk for women with HIV. (This study has been registered at ClinicalTrials.gov under registration no. NCT02103660). IMPORTANCE The results of the Evidence for Contraceptive Options and HIV Outcomes (ECHO) trial, the first large randomized controlled clinical trial comparing the HIV acquisition risk of women receiving DMPA, the levonorgestrel (LNG) implant, or the copper intrauterine device (IUD), did not reveal an increased risk of HIV acquisition for women on any of these three contraceptives. Our study results confirm that the two different progestin-based hormonal contraceptives DMPA and levonogestrel will not increase the risk for HIV infection. Furthermore, DMPA and levonogestrel have only minimal effects on the immune milieu and the microbiota in the vaginal tract, attesting to the safety of these hormonal contraceptives.

RESUMEN

BACKGROUND: Gonadal hormones can modify immune function, which may impact susceptibility to infectious diseases, including Human Immunodeficiency Virus (HIV). There is limited knowledge about how hormonal contraceptives (HC) influence the immune response during the course of use. The CHIME study aims to evaluate the effect of long-acting progestin-based hormonal contraceptives (depot medroxyprogesterone acetate, etonogestrel implant, and levonorgestrel intrauterine device) on immunologic changes in the female genital tract (FGT) and systemic compartment. METHODS: CHIME is an observational cohort study where participants attend 2 visits prior to initiating the HC method of their choice, and then attend 6 visits over 12 months with biological sampling (vaginal swabs, cervicovaginal lavage, cytobrush and blood) for immunological, bacteriological, and virological analyses at each visit. Immune profiling will be evaluated by multi-color flow cytometry to determine how different T-cell subsets, in particular the CD4 T-cell subsets, change during the course of contraceptive use and whether they have different profiles in the FGT compared to the systemic compartment. The study aims are (1) to characterize the alterations in FGT and systemic immune profiles associated with three long-acting progestin-only HC and (2) to evaluate the vaginal microenvironment, determined by 16 s rRNA sequencing, as an individual-level risk factor and moderator of genital and systemic immune profile changes following exposure to three commonly used HC. Data collection started in March 2019 and is scheduled to be completed in October 2024. DISCUSSION: The CHIME study aims to contribute to the body of research designed to evaluate the comparative impact of three long-acting progestin-only HC on innate and adaptive immune functions to understand how immunologic effects alter STI and HIV susceptibility.

RESUMEN

INTRODUCTION: Rwanda has high unmet need for family planning (FP), especially in the postpartum period when women are advised to space pregnancies at least two years for improved maternal-child health. Despite interest in the copper intrauterine device (IUD), a highly cost-effective method, access and uptake remain low. This study aimed to determine factors associated with postpartum IUD (PPIUD) uptake after postpartum family planning (PPFP) counseling as well as provider perceptions of facilitators and barriers to clients' PPIUD uptake. METHODS: Postpartum women who received PPFP counseling and were less than 6 weeks postpartum were recruited for a case-control study in Kigali, Rwanda in 2018. We recruited n = 74 women who had accepted and n = 91 women who had declined the PPIUD. Multivariate logistic regression analyses evaluated associations between women's socio-demographics, FP knowledge and decision-making, and the outcome of PPIUD uptake. Six focus groups (FGs) were conducted with FP providers (n = 24) and community health workers (n = 17) trained to deliver PPFP counseling to assess perceptions of PPFP counseling and facilitators and barriers to PPIUD uptake. FG discussions were recorded, translated, and analyzed for themes. RESULTS: Factors associated (P<0.1) with PPIUD uptake included citing its non-hormonal nature, effectiveness, and duration of protection against pregnancy as advantages. Exclusive male partner control over FP decisions (relative to women's control or joint decision-making) was associated with non-use. Overall, limited knowledge about some aspects of the PPIUD persisted among clients even after counseling. Provider FGs highlighted client concerns, inconsistent FP messaging, and lack of male partner involvement as factors influencing non-use. CONCLUSIONS: Knowledge of the IUD and its benefits was associated with PPIUD uptake. There is need to refine PPFP counseling messages to address remaining knowledge gaps and concerns. Additionally, male partner involvement in FP counseling and decisions with their partners could be a key strategy to increase both PPIUD and FP uptake in Rwanda.

RESUMEN

Abortion is common but highly stigmatized in the United States, and the overturning of Roe v. Wade severely restricted abortion access in many states across the nation. Data reveal that maternal morbidity and mortality are already increasing, and research suggests existing inequities in abortion access across racial/ethnic and socioeconomic groups will be exacerbated. Research has shown that social support (perceived and received aid from one's social network) and social capital (resources accessed through those social connections) can improve access to health services and decrease barriers to care. Given the escalating barriers to abortion, including longer travel distances, it is imperative to better understand the roles of social support and social capital within abortion access, especially for people living on lower incomes and people of color. Our team conducted in-depth interviews with post-abortion patients (n = 18) from an urban abortion clinic in Georgia in 2019 and 2020, shortly after a six-week gestational age abortion limit had been passed but before it was enacted. We examined how people described their social support and social capital - or lack thereof - when making decisions about their pregnancy and their ability to access abortion. We found that social support and social capital - economic support in particular - were key facilitators of both abortion access and parenting, but participants often experienced barriers to economic support within their social networks due to poverty, unstable partnerships, structural inequality, and abortion stigma. Women experienced constraints to their reproductive autonomy, wherein they had no alternatives but abortion. Our findings suggest that increased economic support and de-stigmatization of abortion are needed to improve reproductive autonomy. Our findings also indicate that restricting and outlawing abortion services is significantly detrimental to the well-being of pregnant people, their families and networks, and their communities by perpetuating cycles of poverty and deepening socioeconomic and racial/ethnic inequities.

RESUMEN

PURPOSE: We describe the rationale for and design of an innovative, nested, tripartite prospective observational cohort study examining whether relative estrogen insufficiency-induced inflammation amplifies HIV-induced inflammation to cause end organ damage and worsen age-related co-morbidities affecting the neuro-hypothalamic-pituitary-adrenal axis (Brain), skeletal (Bone), and cardiovascular (Heart/vessels) organ systems (BBH Study). METHODS: The BBH parent study is the Multicenter AIDS Cohort/Women's Interagency HIV Study Combined Cohort Study (MWCCS) with participants drawn from the Atlanta MWCCS site. BBH will enroll a single cohort of n = 120 women living with HIV and n = 60 HIV-negative women, equally distributed by menopausal status. The innovative multipart nested study design of BBH, which draws on data collected by the parent study, efficiently leverages resources for maximum research impact and requires extensive oversight and management in addition to careful implementation. The presence of strong infrastructure minimized BBH study disruptions due to changes in the parent study and the COVID-19 pandemic. CONCLUSION: BBH is poised to provide insight into sex and HIV associations with the neuro-hypothalamic-pituitary-adrenal axis, skeletal, and cardiovascular systems despite several major, unexpected challenges.
