RESUMO

BACKGROUND: Little is known about healthcare providers' (HCPs) contraceptive views for adolescents in Haiti, who experience high rates of unintended pregnancy. We sought to describe HCPs' perspectives on barriers and facilitators to contraceptive care delivery in rural Haiti. METHODS: We conducted a cross-sectional survey and qualitative interviews with HCPs in two rural communities in Haiti from 08/2021-03/2022. We assessed demographics, clinical practice behaviors and explored contraception perspectives according to Theory of Planned Behavior constructs: attitudes, subjective norms, and perceived behavioral control (e.g., people's perceptions of their ability to perform a given behavior, barriers and facilitators of a behavior).15-17 We used descriptive statistics to report proportions and responses to Likert scale and multiple-choice questions. Guided by content analysis, we analyzed interview transcripts through thematic inductive coding and team debriefing. RESULTS: Among 58 respondents, 90% (n = 52) were female and 53% (n = 31) were nurses. Most reported always (n = 16, 28%) or very often (n = 21, 36%) obtaining a sexual history for adolescents. A majority agreed/strongly agreed that clinicians should discuss pregnancy prevention (n = 45, 78%), high-risk sexual behaviors (n = 40, 69%), and should prescribe contraception (n = 41, 71%) to adolescents. The most frequently cited provider-level barriers (i.e., significant or somewhat of a barrier) included insufficient contraception knowledge (n = 44, 77%) and time (n = 37, 64%). HCPs were concerned about barriers at the patient-level (e.g. adolescents' fear of parental notification [n = 37, 64%], adolescents will give inaccurate information about sexual behaviors [n = 25, 43%]) and system-level (e.g. resistance to providing care from administration [n = 33, 57%]). In interviews (n = 17), HCPs generally supported contraception care for adolescents. Many HCPs echoed our quantitative findings on concerns about privacy and confidentiality. HCPs reported concerns about lack of contraception education leading to misconceptions, and community and parental judgement. HCPs expressed interest in further contraception training and resources and noted the importance of providing youth-friendly contraceptive care. CONCLUSIONS: While HCPs support contraceptive care, we identified actionable barriers to improve care for adolescents in rural Haiti. Future efforts should include increasing HCP knowledge and training, community and parent coalition building to increase contraception support and offering youth-friendly contraceptive care to offset risk for related adverse health outcomes in adolescents in rural Haiti.

RESUMO

Objective: To determine the effects of a baseline ovarian cyst on ovulation induction/intrauterine insemination (OI/IUI) cycle outcomes. Methods: A retrospective cohort analysis of 270 patients and 461 OI/IUI cycles performed between 2011 and 2021 was performed. The exposure variable was a simple appearing ovarian cyst diagnosed at baseline ultrasound measuring ≥10 mm with an estradiol level <75 ng/mL. The primary outcome analyzed was an ultrasound-confirmed intrauterine pregnancy. Secondary outcomes included positive pregnancy test and live birth. Summary data were presented with percentages, mean (standard deviation), or median (interquartile range). Comparisons of dichotomous variables were performed with the chi-square test, and continuous variables were compared using t-test. Regression analysis was performed using a general linear model. p-Values <0.05 were considered statistically significant. Results: The clinical pregnancy rate was nominally higher in the group without a cyst present at baseline ultrasound compared with those cycles with a simple cyst present, but the difference was not statistically significant (45/300 [15%] vs. 15/161 [9.3%], risk ratio [RR] 0.63 [0.36, 1.1]). After adjusting for BMI ≥30 and age ≥35, there remained no significant difference in clinical pregnancy rate (adjusted RR 0.65 [0.37, 1.1]). Conclusion: Given the present data, it is reasonable to proceed with IUI in the case of a baseline simple ovarian cyst. However, this finding may have an impact on clinical pregnancy outcomes in OI/IUI, and further research on the topic is warranted. Although this study was underpowered with fewer cycles than needed to demonstrate a significant difference, the point estimate suggests that the difference in clinical pregnancy rate could be ∼35%.

RESUMO

BACKGROUND: Some studies indicate that pregnant Kenyan women were concerned about Coronavirus disease 2019 (COVID-19) exposure during maternity care. We assessed concern regarding COVID-19 exposure and any impact on antenatal care (ANC) enrollment and/or hospital delivery among pregnant women living with human immunodeficiency virus (HIV) in Kenya. METHODS: Data were collected from 1,478 pregnant women living with HIV enrolled in prevention of mother to child transmission of HIV (PMTCT) care at 12 Kenyan hospitals from October 2020 to July 2022. Surveys were conducted when women first presented for PMTCT services at the study hospital and asked demographic questions as well as items related to concerns about COVID-19. A 5-point Likert scale (strongly disagree to strongly agree) assessed concerns about COVID-19 exposure and travel challenges. Gestational age at PMTCT enrollment, number of ANC appointments attended, and delivery location were compared among women who expressed COVID-19 concerns and those who did not. RESULTS: Few women reported delaying antenatal care (4.7%), attending fewer antenatal care appointments (5.0%), or having concerns about a hospital-based delivery (7.7%) because of COVID-19. More (25.8%) reported travel challenges because of COVID-19. There were no significant differences in gestational age at enrollment, number of ANC appointments, or rates of hospital-based delivery between women with concerns about COVID-19 and those without, CONCLUSION: Few pregnant women living with HIV expressed concerns about COVID-19 exposure in the context of routine ANC or delivery care. Women with and without concerns had similar care seeking behaviors. The recognized importance of routine ANC care and facility-based deliveries may have contributed to these positive pregnancy indicators, even among women who worried about COVID-19 exposure.

RESUMO

BACKGROUND: Research priorities are best defined through engagement with communities who will be impacted by the research and have lived experience of the topics to be studied. We aimed to establish a pediatric rare disease community stakeholder group and empower them in (1) eliciting perspectives from affected families in the wider region and (2) synthesizing collective ideas into a research agenda focused on shared ethical, legal, and social implications (ELSI) across rare disease. METHODS: This two-year project utilized a community-centered approach to engage rare disease community members as equal partners in developing a research agenda for ELSI in rare disease. We established "Rare Voices" (RV), a 22-member stakeholder group of patients, parents, clinicians and researchers. Following capacity-building trainings, RV designed and conducted listening sessions with teen patients and parents of children with rare diseases to explore challenges, positive experiences, and ethical concerns. Listening session findings were synthesized and contextualized into research topics, which RV members further refined and prioritized. We used established measures to assess RV member engagement and satisfaction. RESULTS: From 14 listening sessions with parents (n = 52) and teen patients (n = 13), RV identified eight core research topics as most important for future rare disease research: coordinating care, communication, accessing resources and care, impact on family unit, community and support in society, mental health and identity, ethical aspects of care, and uncertainty. RV members were highly engaged throughout the two-year project and reported high levels of satisfaction with the experience and research agenda. CONCLUSIONS: Through capacity-building and authentic engagement, this project resulted in a community-led rare disease research agenda to guide future rare disease ELSI research that aligns with patients' and families' priorities. An environment of equal partnership and respect created a space for mutual learning where community members were empowered to shape the research agenda based on their collective experiences. The agenda recognizes the shared psychosocial and healthcare experiences of rare disease and offers practical areas of research to address patient and family needs.

RESUMO

PURPOSE: Research-based theater uses drama to communicate research findings to audiences beyond those that typically read peer-reviewed journals. We applied research-based theater to translate qualitative research findings on the impact of the COVID-19 pandemic on different segments of U.S. society. APPROACH: Theater artists and public health researchers collaborated to create a collection of eight monologues from systematically sourced, peer-reviewed publications. Following three virtual performances in Spring, 2021, audience members were invited to complete a survey. SETTING/PARTICIPANTS: Audience survey respondents (n = 120) were mostly U.S.-based and were diverse in terms of age, race/ethnicity, gender, profession, and experience attending theater. METHOD: We summarized closed-ended responses and explored patterns by demographic characteristics. We synthesized themes of open-ended responses with inductive coding. RESULTS: Audience members somewhat/strongly agreed that COVID Monologues increased their knowledge (79.4%), represented the reality of the U.S. COVID-19 epidemic (95.7%), and offered new perspectives on what people had been experiencing (87.5%). Most also agreed research-based theater is an effective means of understanding health research (93.5%) and can promote community resilience in times of public health crisis (83.2%). Mann-Whitney U tests suggested less positive reactions from demographics that were not well-represented in monologue characters (cisgender men, Hispanics). Qualitative comments suggested audience members valued monologues that offered self-reflection and validation of their own COVID-19 experiences through relatable characters as well as those that offered insight into the experiences of people different from themselves. CONCLUSION: This work adds to evidence that research-based theater can help build knowledge and emotional insight around a public health issue. As these elements are foundational to pro-social, preventative health behaviors, research-based theater may have a useful role in promoting collective response to public health crises like COVID-19. Our method of systematically-sourcing research for theater-based dissemination could be extended to target more specific audiences with actionable behaviors.

RESUMO

Antiretroviral therapy (ART) adherence during and after pregnancy is essential to reduce perinatal transmission of HIV. However, little is known about adherence during the intrapartum and early postpartum inpatient hospital stay. Using secondary data from a hospital-based cohort study focused on the relationship between birthweight and engagement in HIV care, we examined the magnitude of, reasons for, and factors associated with incomplete intrapartum and early postpartum ART adherence among adult women (18 years or older) living with HIV who delivered within the previous two weeks at one of five hospitals in Accra, Ghana. Of the 142 enrolled participants who had complete adherence data and reported being on ART at the time of hospital admission, 43% (61/142) reported missing at least one ART dose during labor, delivery, and postpartum, including almost 20% (28/142) missing 2 or more consecutive doses. Women who reported frequently missing ART doses during pregnancy had higher odds of reporting missed doses during their intrapartum and postpartum hospital stays. Among those with inpatient ART interruption, the most frequently cited reasons were: forgetting medication at home (42%) and challenges of being in or recovering from labor (29%). Maternal perception of infant health at birth, hospital level of care, and frequency of missing HIV medications during pregnancy were associated with incomplete ART adherence during the intrapartum and early postpartum inpatient stay. An enabling clinical environment to facilitate access to ART during inpatient stays may have positive implications for ART adherence.

RESUMO

OBJECTIVE: To determine whether cyclic strain affects fibroid cell cytoskeletal organization, proliferation, and collagen synthesis differently than myometrial cells. DESIGN: A basic science study using primary cultures of patient-matched myometrial and fibroid cells. SETTING: Academic laboratory. PATIENT(S): Premenopausal women undergoing myomectomy or hysterectomy for the treatment of symptomatic uterine fibroids. INTERVENTION(S): Application of uniaxial strain patterns mimicking periovulation, menses, or dysmenorrhea using the Flexcell tension system or static control. Secondarily, inhibition of G protein-coupled estrogen receptor-1 and phosphatidylinositol 3-kinase. MAIN OUTCOME MEASURE(S): Cell alignment, cell number, and collagen content. RESULT(S): Menses-strained cells demonstrated the most variation in cell alignment, cell proliferation, and procollagen content between myometrial and fibroid cells. Procollagen content decreased in myometrial cells with increasing strain amplitude and decreasing frequency. G protein-coupled estrogen receptor-1 inhibition decreases cellular alignment in the presence of strain. CONCLUSION(S): Mechanotransduction affecting cytoskeletal arrangement through the G protein-coupled estrogen receptor-1-phosphatidylinositol 3-kinase pathway is altered in fibroid cells. These results highlight the importance of incorporating mechanical stimulation into the in vitro study of fibroid pathology.

RESUMO

Fears of relationship dissolution and the inability to bear healthy children remain barriers to HIV testing in sub-Saharan Africa. Pre-exposure prophylaxis (PrEP) carries both clinical and symbolic benefits that counter these fears. We conducted a pilot messaging intervention through Uganda's assisted partner notification (APN) program, where providers assist HIV-positive index clients in notifying sexual partners and encourage testing. We randomized providers at three clinics to implement phone scripts over two months with (1) gain-framed or (2) loss-framed information about PrEP and childbearing; or (3) usual care. In 23 in-depth interviews with providers, index clients, and partners, five major themes emerged on intervention acceptability and feasibility: (1) value of PrEP and childbearing messaging in APN; (2) value of this messaging coming earlier in APN; (3) overall preference for gain-framed messages; (4) need to tailor timing of messaging; and (5) need for messaging outside of APN. Register data (109 index clients, 145 partners) indicated most index clients (95%) wanted their potential conception partners informed about PrEP. Preliminary trends suggest the intervention sites outperformed usual care in testing rates among potential conception partners. Messaging that highlights PrEP and safe childbearing may be a promising new communication strategy to promote HIV testing.

RESUMO

Objective: Currently available contraceptive methods do not meet the needs of all users. We sought to explore preferences of potential end-users regarding an on-demand, non-hormonal female contraceptive currently under development, using a web-based survey. Study design: We recruited respondents for an exploratory survey via web link on Amazon Mechanical Turk (MTurk). Individuals were eligible if they were 18-44 years of age, identified as cis-gender female, were English-speaking, not pregnant, and had used barrier contraception previously. Respondents provided demographic characteristics and a basic reproductive history. We then provided a brief description of the potential contraceptive. Respondents were asked about their interest in the proposed contraceptive and preferences for method attributes. Results: A total of 500 respondents completed the survey. Three-quarters of respondents were <35 years of age and 48.2% were currently using a barrier contraceptive method. Three-fourths of respondents (73.8%) expressed interest in using the contraceptive under development. The majority wanted the method to be small (≤2 inches), rod-shaped, and low cost (<$5 per use). More than half (59.4%) said it was important to be able to use the method without partners' knowledge. The most reported potential concerns were vaginal irritation (51.6%) and lack of effectiveness (46.4%). Sixty percent of respondents were confident they could use the method correctly. Discussion: Available contraceptive methods lack attributes preferred by some users. Development of new contraceptives frequently does not involve end-user input early in the development process. Individuals in this sample displayed interest in the proposed contraceptive and expressed preferences that can inform the further development of this method.

RESUMO

BACKGROUND: Atrial fibrillation is the most common arrhythmia syndrome and causes significant morbidity and mortality. Current therapeutics, however, have limited efficacy. Notably, many therapeutics shown to be efficacious in animal models have not proved effective in humans. Thus, there is a need for a drug screening platform based on human tissue. The aim of this study was to develop a robust protocol for generating atrial cardiomyocytes from human-induced pluripotent stem cells. METHODS: A novel protocol for atrial differentiation, with optimized timing of retinoic acid during mesoderm formation, was compared to two previously published methods. Each differentiation method was assessed for successful formation of a contractile syncytium, electrical properties assayed by optical action potential recordings and multi-electrode array electrophysiology, and response to the G-protein-gated potassium channel activator, carbamylcholine. Atrial myocyte monolayers, derived using the new differentiation protocol, were further assessed for cardiomyocyte purity, gene expression, and the ability to form arrhythmic rotors in response to burst pacing. RESULTS: Application of retinoic acid at day 1 of mesoderm formation resulted in a robust differentiation of atrial myocytes with contractile syncytium forming in 16/18 differentiations across two cell lines. Atrial-like myocytes produced have shortened action potentials and field potentials, when compared to standard application of retinoic acid at the cardiac mesoderm stage. Day 1 retinoic acid produced atrial cardiomyocytes are also carbamylcholine sensitive, indicative of active Ikach currents, which was distinct from ventricular myocytes and standard retinoic addition in matched differentiations. A current protocol utilizing reduced Activin A and BMP4 can produce atrial cardiomyocytes with equivalent functionality but with reduced robustness of differentiation; only 8/17 differentiations produced a contractile syncytium. The day 1 retinoic acid protocol was successfully applied to 6 iPSC lines (3 male and 3 female) without additional optimization or modification. Atrial myocytes produced could also generate syncytia with rapid conduction velocities, > 40 cm s-1, and form rotor style arrhythmia in response to burst pacing. CONCLUSIONS: This method combines an enhanced atrial-like phenotype with robustness of differentiation, which will facilitate further research in human atrial arrhythmia and myopathies, while being economically viable for larger anti-arrhythmic drug screens.

RESUMO

BACKGROUND: Lifestyle Africa is an adapted version of the Diabetes Prevention Program designed for delivery by community health workers to socioeconomically disadvantaged populations in low- and middle-income countries (LMICs). Results from the Lifestyle Africa trial conducted in an under-resourced community in South Africa indicated that the programme had a significant effect on reducing haemoglobin A1c (HbA1c). OBJECTIVE: To estimate the cost of implementation and the cost-effectiveness (in cost per point reduction in HbA1c) of the Lifestyle Africa programme to inform decision-makers of the resources required and the value of this intervention. METHODS: Interviews were held with project administrators to identify the activities and resources required to implement the intervention. A direct-measure micro-costing approach was used to determine the number of units and unit cost for each resource. The incremental cost per one point improvement in HbA1c was calculated. RESULTS: The intervention equated to 71 United States dollars (USD) in implementation costs per participant and a 0.26 improvement in HbA1c per participant. CONCLUSIONS: Lifestyle Africa reduced HbA1c for relatively little cost and holds promise for addressing chronic disease in LMIC. Decision-makers should consider the comparative clinical effectiveness and cost-effectiveness of this intervention when making resource allocation decisions. TRIAL REGISTRATION: Trial registration is at ClinicalTrials.gov (NCT03342274).

RESUMO

BACKGROUND: Individuals with substance use disorders (SUD) have disproportionately high rates of unintended pregnancy. Reducing harm associated with this risk and its biopsychosocial consequences requires evidence-based, non-coercive interventions that ensure access to contraception for individuals who choose to prevent pregnancy. We examined feasibility and impact of SexHealth Mobile, a mobile unit-based intervention that aimed to increase access to patient-centered contraceptive care for individuals in SUD recovery programs. METHODS: We conducted a quasi-experimental study (enhanced usual care [EUC] followed by intervention) at three recovery centers with participants (n = 98) at risk for unintended pregnancy. EUC participants were offered printed information on community locations where they could access contraception care. SexHealth Mobile participants were offered same-day, onsite clinical consultation on a medical mobile unit and contraception if desired. The primary outcome was use of contraception (hormonal or intrauterine device) at one-month post-enrollment. Secondary outcomes were at two-weeks and three-months. Confidence in preventing unintended pregnancy, reasons for non-use of contraception at follow-up, and intervention feasibility were also assessed. RESULTS: Participants (median age = 31, range 19-40) enrolled in the intervention period were almost 10 times more likely to be using contraception at one-month (51.5%) versus the those enrolled in the EUC period (5.4%) (unadjusted relative risk [URR] = 9.3 [95%CI: 2.3-37.1]; adjusted relative risk [ARR] = 9.8 [95%CI: 2.4-39.2]). Intervention participants were also more likely to be using contraception at 2-weeks (38.7% vs. 2.6%; URR = 14.3 [95%CI: 2.0-104.1]) and three-months (40.9% vs. 13.9%; URR = 2.9 [95% CI: 1.1-7.4]). EUC participants reported more barriers (cost, time) and less confidence in preventing unintended pregnancies. Mixed-methods feasibility data indicated high acceptability and feasible integration into recovery settings. CONCLUSIONS: Mobile contraceptive care based on principles of reproductive justice and harm reduction reduces access barriers, is feasible to implement in SUD recovery settings, and increases contraception use. Expanding interventions like SexHealth Mobile may help reduce harm from unintended pregnancies among individuals in SUD recovery. Trial Registration NCT04227145.

RESUMO

BACKGROUND: Adolescents and young adults (AYAs) in Haiti experience a high unintended pregnancy rate, in part due to unmet contraception needs. Little is known about AYA opinions of and experiences with contraception that may explain remaining gaps in coverage. We aimed to describe barriers and facilitators to contraception use among AYAs in Haiti. METHODS: We conducted a cross-sectional survey and semi-structured qualitative interviews with a convenience sample of AYA females aged 14-24 in two rural communities in Haiti. The survey and semi-structured interviews assessed demographics, sexual health and pregnancy prevention behaviors and explored contraception opinions and experiences according to Theory of Planned Behavior constructs: attitudes, subjective norms, and perceived behavioral control. We used descriptive statistics to report means and responses to Likert scale and multiple-choice questions. Guided by content analysis, we analyzed interview transcripts through inductive coding and team debriefing. RESULTS: Among 200 survey respondents, 94% reported any past vaginal sexual activity, and 43% reported ever being pregnant. A large majority were trying to avoid pregnancy (75%). At last sexual activity, 127 (64%) reported use of any contraceptive method; Among them, condoms were the most common method (80%). Among those with previous condom use, most reported use less than half the time (55%). AYAs were concerned about parental approval of birth control use (42%) and that their friends might think they are looking for sex (29%). About one-third felt uncomfortable going to a clinic to ask for birth control. In interviews, AYAs desired pregnancy prevention but frequently noted concerns about privacy and parental, community and healthcare provider judgement for seeking care for reproductive health needs. AYAs also noted a lack of contraception knowledge, evident by frequent misconceptions and associated fears. CONCLUSION: Among AYAs in rural Haiti, a large majority were sexually active and desire pregnancy avoidance, but few were using effective contraception due to numerous concerns, including privacy and fear of judgement. Future efforts should address these identified concerns to prevent unintended pregnancy and improve maternal and reproductive health outcomes in this population.

RESUMO

Most research on glutamate spillover focuses on the deleterious consequences of postsynaptic glutamate receptor overactivation. However, two decades ago, it was noted that the glial coverage of hippocampal synapses is asymmetric: astrocytic coverage of postsynaptic sites exceeds coverage of presynaptic sites by a factor of four. The fundamental relevance of this glial asymmetry remains poorly understood. Here, we used the glutamate biosensor iGluSnFR, and restricted its expression to either CA3 or CA1 neurons to visualize glutamate dynamics at pre- and postsynaptic microenvironments, respectively. We demonstrate that inhibition of the primarily astrocytic glutamate transporter-1 (GLT-1) slows glutamate clearance to a greater extent at presynaptic compared to postsynaptic membranes. GLT-1 expression was reduced early in a mouse model of AD, resulting in slower glutamate clearance rates at presynaptic but not postsynaptic membranes that opposed presynaptic short-term plasticity. Overall, our data demonstrate that the presynapse is particularly vulnerable to GLT-1 dysfunction and may have implications for presynaptic impairments in a variety of brain diseases.

RESUMO

Background: The optimal protocol for minimal stimulation in vitro fertilization (IVF) has yet to be established. This study aims to determine if the use of gonadotropin-releasing hormone (GnRH) antagonist during minimal stimulation improves outcomes. Materials and Methods: All cycles designated as minimal stimulation from 2014 to 2016 from the Society for Assisted Reproductive Technology Clinic Online Reporting System were identified. Cycles in which GnRH antagonist was administered (n = 5984) were compared to those that did not receive it (n = 7066). Wilcoxon's rank-sum test and chi-square test were used to analyze continuous and categorical variables. Results: A total of 6750 patients undergoing 13,050 cycles were included. GnRH antagonist use was associated with a significantly higher total gonadotropin dosage (median 975.0 [interquartile range, IQR, 600.0, 1575.0] vs. median 660.0 [IQR 375.0, 975.0], p < 0.001), lower cycle cancelation rate (11.3% vs. 13.6%, p < 0.001; OR 1.24, 95% CI 1.12-1.38, p < 0.001), and higher live birth rate (4.3% vs. 2.1%, p < 0.001; OR 0.47, 95% CI 0.39-0.58, p < 0.001). GnRH antagonist use was associated with a significantly higher live birth rate in women ≥35 years of age (2.7% vs. 0.9%, p < 0.001; OR 0.34, 95% CI 0.25-0.47, p < 0.001) and antimullerian hormone <1 (4.9% vs. 2.6%, p = 0.004; OR 0.52, 95% CI 0.33-0.81, p = 0.004). Conclusion: The use of GnRH antagonist suppression during minimal stimulation IVF is associated with an improved live birth rate, especially in older women and in women with diminished ovarian reserve. Although GnRH antagonist use may increase costs, it significantly decreases cancelation rate, increases number of embryos cryopreserved, and should be encouraged for minimal stimulation IVF.

RESUMO

BACKGROUND: Adolescent and young adult (AYA) females in low- and middle-income countries often face disparities in menstrual health (MH). Poor MH and lack of sexual and reproductive health education leads to school absenteeism, increasing risk for adverse psychosocial and educational outcomes. Further, disasters (e.g., earthquakes) are linked with unsafe living environments and sanitation facilities for women. We sought to describe MH perspectives and practices among AYAs in rural Haiti. METHODS: We conducted a cross-sectional survey in two rural communities in Haiti. AYA females aged 14-24 years completed questions on demographics, the Menstrual Practice Needs Scale (36 items; MPNS-36) and the Menstrual Practices Questionnaire (4 items). We performed descriptive statistics and Chi square or Fisher's Exact tests to compare responses among sub-groups. RESULTS: Among 200 respondents, the median age was 20 years (IQR 17-22). 51% (95% CI 44%, 58%; 102/200) were currently attending school at least 3 days/week and 97% (94%, 99%; 193/200) were not married. According to the MPNS-36, 68% (62%, 74%; 136/200) of participants had unmet MH needs. Seventy-one (77%) reused some of their menstrual materials during their last menstruation. During their last menstruation, 44% (37%, 50%; 87/200) reported they often or always skipped school because they had their menses, and 31% (25%, 37%; 62/200) sometimes skipped. Many felt always or often worried that someone or something would harm them while they were changing their menstrual materials at home and at school. CONCLUSIONS: Among AYAs in rural Haiti, three-quarters reported menses-related school absenteeism and two-thirds had unmet MH needs. AYA females often lacked a safe environment to change their menstrual materials. Given recent disasters in Haiti, (August 2021 earthquake), safe environments for MH are critically needed to offset risk for poor psychosocial and health outcomes. Future efforts to improve MH among AYAs in Haiti are needed to ensure access to MH resources and school attendance.


Adolescents and young adult (AYA) females in low- and middle-income countries can often lack adequate access to materials to manage their menstruation, in addition to safe spaces to change those materials. This lack of access, in addition to low levels of reproductive health education, can cause AYAs to miss school, leading to increased risk of worse psychosocial and educational outcomes. In addition, disasters (e.g., earthquakes) are linked with unsafe living environments and sanitation facilities for women. We sought to describe AYA menstrual practices and perspectives on menstrual hygiene in rural Haiti. In two rural communities in Haiti, AYA females aged 14­24 years answered questions on their demographics and menstrual hygiene practices and environments. Two-thirds of AYAs had unmet menstrual hygiene needs and three-quarters reported they skipped school (with any frequency) due to their menses. Further, more than half worried that something or someone would harm them while they were changing their menstrual materials at home and at school. AYA females often lacked a safe environment to change their menstrual materials. Given recent disasters and political unrest in Haiti, (August 2021 earthquake), it is important to improve menstrual hygiene in these LMICs to ensure safe enviornments for managing menstruation and school attendance and ultimately improve psychosocial and health outcomes.

RESUMO

BACKGROUND: Children with acute respiratory tract infections (ARTIs) receive ≈11.4 million unnecessary antibiotic prescriptions annually. A noted contributor is inadequate parent-clinician communication, however, efforts to reduce overprescribing have only indirectly targeted communication or been impractical. OBJECTIVES: Compare two feasible (higher vs lower intensity) interventions for enhancing parent-clinician communication on the rate of inappropriate antibiotic prescribing. DESIGN: Multisite, parallel group, cluster randomised comparative effectiveness trial. Data collected between March 2017 and March 2019. SETTING: Academic and private practice outpatient clinics. PARTICIPANTS: Clinicians (n=41, 85% of eligible approached) and 1599 parent-child dyads (ages 1-5 years with ARTI symptoms, 71% of eligible approached). INTERVENTIONS: All clinicians received 20 min ARTI diagnosis and treatment education. Higher intensity clinicians received an additional 50 min communication skills training. All parents viewed a 90 second antibiotic education video. MAIN OUTCOMES AND MEASURES: Inappropriate antibiotic treatment was assessed via blinded medical record review by study clinicians and a priori defined as prescriptions for the wrong diagnosis or use of the wrong agent. Secondary outcomes were revisits, adverse drug reactions (both assessed 2 weeks after the visit) and parent ratings of provider communication, shared decision-making and visit satisfaction (assessed at end of the visit on Likert-type scales). RESULTS: Most clinicians completed the study (n=38, 93%), were doctors (n=25, 66%), female (n=30, 78%) and averaged 8 years in practice. All parent-child dyad provided data for the main outcome (n=855 (54%) male, n=1043 (53%) <2 years). Inappropriate antibiotic prescribing was similar among patients who consulted with a higher intensity (54/696, 7.8%) versus a lower intensity (85/904, 9.4%) clinician. A generalised linear mixed effect regression model (adjusted for the two-stage nested design, clinician type, clinic setting and clinician experience) revealed that the odds of receiving inappropriate antibiotic treatment did not significantly vary by group (AOR 0.99, 95% CI: 0.52 to 1.89, p=0.98). Secondary outcomes of revisits and adverse reactions did not vary between arms, and parent ratings of satisfaction with quality of parent-provider communication (5/5), shared decision making (9/10) and visit satisfaction (5/5) were similarly high in both arms. CONCLUSIONS AND RELEVANCE: Rate of inappropriate prescribing was low in both arms. Clinician education coupled with parent education may be sufficient to yield low inappropriate antibiotic prescribing rates. The absence of a significant difference between groups indicates that communication principles previously thought to drive inappropriate prescribing may need to be re-examined or may not have as much of an impact in practices where prescribing has improved in recent years.

RESUMO

BACKGROUND: Gaps in the provision of guideline-adherent prevention of mother-to-child transmission of HIV (PMTCT) services and maternal retention in care contribute to nearly 8000 Kenyan infants becoming infected with HIV annually. Interventions that routinize evidence-based PMTCT service delivery and foster consistent patient engagement are essential to eliminating mother-to-child transmission of HIV. The HITSystem 2.1 is an eHealth intervention that aims to improve retention in PMTCT services and viral load monitoring, using electronic alerts to providers and SMS to patients. This study will evaluate the impact, implementation, and cost-effectiveness of HITSystem 2.1. METHOD: This cluster randomized trial will be conducted at 12 study hospital (6 intervention, 6 control). Pregnant women living with HIV who have initiated PMTCT care ≤36 weeks gestation are eligible. Women enrolled at control hospitals will receive standard-of-care PMTCT services. Women enrolled at intervention hospitals will receive standard-of-care PMTCT services plus enhanced HITSystem 2.1 tracking. Mixed logistic regression models will compare the arms on two primary outcomes: (1) completed guideline-adherence PMTCT services and (2) viral suppression at both delivery and 6 months postpartum. We will assess associations between provider and patient characteristics (disclosure status, partner status, depression, partner support), PMTCT knowledge, and motivation with retention outcomes. Using the RE-AIM model, we will also assess implementation factors to guide sustainable scale-up. Finally, a cost-effectiveness analysis will be conducted. DISCUSSION: This study will provide insights regarding the development and adaptation of eHealth strategies to meet the global goal of eliminating new HIV infections in children and optimizing maternal health through PMTCT services. If efficacious, implementation and cost-effectiveness data gathered in this study will guide scale-up across Kenyan health facilities. TRIAL REGISTRATION: This study was registered at clinicaltrials.gov (NCT04571684) on October 1, 2020.

RESUMO

BACKGROUND: Low- and middle-income countries (LMICs) are experiencing major increases in diabetes and cardiovascular conditions linked to overweight and obesity. Lifestyle interventions such as the United States National Diabetes Prevention Program (DPP) developed in high-income countries require adaptation and cultural tailoring for LMICs. The objective of this study was to evaluate the efficacy of "Lifestyle Africa," an adapted version of the DPP tailored for an underresourced community in South Africa compared to usual care. METHODS AND FINDINGS: Participants were residents of a predominantly Xhosa-speaking urban township of Cape Town, South Africa characterized by high rates of poverty. Participants with body mass index (BMI) ≥ 25 kg/m2 who were members of existing social support groups or "clubs" receiving health services from local nongovernmental organizations (NGOs) were enrolled in a cluster randomized controlled trial that compared Lifestyle Africa (the intervention condition) to usual care (the control condition). The Lifestyle Africa intervention consisted of 17 video-based group sessions delivered by trained community health workers (CHWs). Clusters were randomized using a numbered list of the CHWs and their assigned clubs based on a computer-based random allocation scheme. CHWs, participants, and research team members could not be blinded to condition. Percentage weight loss (primary outcome), hemoglobin A1c (HbA1c), blood pressure, triglycerides, and low-density lipoprotein (LDL) cholesterol were assessed 7 to 9 months after enrollment. An individual-level intention-to-treat analysis was conducted adjusting for clustering within clubs and baseline values. Trial registration is at ClinicalTrials.gov (NCT03342274). Between February 2018 and May 2019, 782 individuals were screened, and 494 were enrolled. Participants were predominantly retired (57% were receiving a pension) and female (89%) with a mean age of 68 years. Participants from 28 clusters were allocated to Lifestyle Africa (15, n = 240) or usual care (13, n = 254). Fidelity assessments indicated that the intervention was generally delivered as intended. The modal number of sessions held across all clubs was 17, and the mean attendance of participants across all sessions was 61%. Outcome assessment was completed by 215 (90%) intervention and 223 (88%) control participants. Intent-to-treat analyses utilizing multilevel modeling included all randomized participants. Mean weight change (primary outcome) was -0.61% (95% confidence interval (CI) = -1.22, -0.01) in Lifestyle Africa and -0.44% (95% CI = -1.06, 0.18) in control with no significant difference (group difference = -0.17%; 95% CI = -1.04, 0.71; p = 0.71). However, HbA1c was significantly lower at follow-up in Lifestyle Africa compared to the usual care group (mean difference = -0.24, 95% CI = -0.39, -0.09, p = 0.001). None of the other secondary outcomes differed at follow-up: systolic blood pressure (group difference = -1.36; 95% CI = -6.92, 4.21; p = 0.63), diastolic blood pressure (group difference = -0.39; 95% CI = -3.25, 2.30; p = 0.78), LDL (group difference = -0.07; 95% CI = -0.19, 0.05; p = 0.26), triglycerides (group difference = -0.02; 95% CI = -0.20, 0.16; p = 0.80). There were no unanticipated problems and serious adverse events were rare, unrelated to the intervention, and similar across groups (11 in Lifestyle Africa versus 13 in usual care). Limitations of the study include the lack of a rigorous dietary intake measure and the high representation of older women. CONCLUSIONS: In this study, we found that Lifestyle Africa was feasible for CHWs to deliver and, although it had no effect on the primary outcome of weight loss or secondary outcomes of blood pressure or triglycerides, it had an apparent small significant effect on HbA1c. The study demonstrates the potential feasibility of CHWs to deliver a program without expert involvement by utilizing video-based sessions. The intervention may hold promise for addressing cardiovascular disease (CVD) and diabetes at scale in LMICs. TRIAL REGISTRATION: ClinicalTrials.gov NCT03342274.
