Network determinants of relationship influence on HIV prevention decision-making among people in the social networks of women who have experienced incarceration in the US
Many cisgender women in the US who have experienced incarceration are at substantial risk for HIV acquisition after they return to the community. Various network interventions have been leveraged for HIV prevention in this population. The objective of this study was to identify network and relationship determinants of influence on HIV prevention decisions, including PrEP. We conducted interviews with a network mapping exercise with participants recruited from the social and sexual networks of women who had experienced incarceration. Participants enumerated important individuals in their lives from the past six months and provided demographic and relationship data as well as whether each relationship influenced their HIV prevention decisions. We abstracted network data from the interview transcripts and described the data set using descriptive statistics and network density graphs. To measure associations between characteristics at each level and whether a relationship was considered influential regarding PrEP decision-making, we use multiple logistic regression with random intercepts for each respondent. We interviewed 32 participants, average age 33.5 years (SD = 8.98), majority female (n = 28, 87.5%), white (n = 23, 71.8%), heterosexual/straight (n = 25, 78.1%), and with a personal history of incarceration (n = 29, 90%). They reported 253 relationships (119 family, 116 friend, 18 sexual relationships). Most adult network members had used drugs or alcohol (n = 182, 80.9%), and of those, 30.8% had used them with the participant (n = 53). The mean network size was 7 (SD = 4) and network density was 52.2%. In the full model, significant positive predictors of an influential relationship included participant non-heterosexual identity (OR 27.8), older average age in the network (OR 3.9 per standard deviation), and being a current or prior sexual partner (OR 10.1). Significant negative predictors included relationships with individuals who use or had used drugs (OR 0.28), longer average relationship duration in the network (OR 0.09) and being in a network with at least one sexual partner (OR 0.2). There are significant positive and negative determinants of relationship influence related to PrEP at individual-, dyad-, relationship-, and network-levels. These support using nuanced network approaches to behavior change that respect and leverage the diversity of relationships that comprise the social networks of women who have experienced incarceration.
Understanding gaps in guideline-recommended adult congenital heart disease care: Data from 12 US health care centers
•Adults with CHD at tertiary centers have significant gaps in recommended ACHD care.•Nonsevere CHD, nonphysiologic class conditions, and age 40+ have higher care gaps.•Patients with gaps in specialist visits have higher gaps in recommended testing.•COVID-19 pandemic has worsened ACHD care gaps.•Enhancing interdisciplinary collaborations at tertiary centers can improve ACHD care. Guidelines recommend lifelong care with adult congenital heart disease (ACHD) specialists for adults with congenital heart disease (CHD). However, such gaps in visits at specialized ACHD centers have not been well-characterized from diverse US settings. This retrospective study analyzed data from 12 centers in the national Patient-Centered Clinical Research Network. CHD conditions were classified using International Classification of Disease codes and a hierarchical algorithm. ACHD specialists were identified by investigators and encounter volumes. Data from the ‘Pre-COVID’ (2015-2019) and ‘COVID’ (2020-2022) periods were analyzed separately. Main outcome measures were: 1) Gaps in any ACHD specialist visit and recommended testing throughout the study period. 2) Gaps in recommended ACHD follow-up care. During pre-COVID (N = 18,934) and COVID (N = 22,453) periods, between 55.3%-55.8% were males, 27.2%-31.0% were 40+ years, 18.2%-19.6% had severe CHD, and 52.7%-55.0% had CHD physiologic class B-D conditions. Between 47.0%-54.5% had gaps in specialist visit and 13.0%-24.6% had gaps in all the testing. Patients with gaps in specialist visits were 6.33-9.44 times more likely to have gaps in testing. Gaps were more common among patients with moderate (adjusted odds ratio [AOR]: 2.61) and simple (AOR: 2.84) CHD, those aged 40+ (AOR: 1.53) and nonphysiologic class conditions (AOR 1.51). In both periods, 64.1%-71.5% of patients had gaps in follow-up care. Three-quarters of adults with CHD experienced gaps in specialized ACHD care while receiving services at high volume comprehensive tertiary health centers. To address these gaps, interventions such as fostering physician collaboration within tertiary centers might be needed, and targeted to patients with less severe CHD, nonphysiologic class conditions, and those aged 40+ years.
Ethical inclusion: Risks and benefits of research from the perspective of perinatal people with opioid use disorders who have experienced incarceration
Research ethics guidelines and emphasis on representation in research guide the inclusion of marginalized groups, including people with perinatal opioid use disorders (OUD) and people experiencing incarceration in the United States. However, insights from participants regarding the risks and benefits of participation are not adequately considered. The aim of this study was to examine the risks and benefits of research participation from the perspective of pregnant/postpartum people with OUD who have experienced incarceration. We recruited people who had experience with perinatal incarceration and were either currently pregnant or postpartum, and at least 18 years old. All participants met the clinical criteria for OUD. Our study did not have exclusion criteria based on gender, race, or ethnicity. Participants were either currently incarcerated at the North Carolina Correctional Institute for Women in Raleigh, North Carolina, United States or had previously experienced perinatal incarceration and were recruited from a perinatal substance use disorder treatment program located in North Carolina. Between 9/2021-4/2022, we completed 12 interviews with pregnant/postpartum people with OUD, approximately half who were currently incarcerated and half with a recent history of perinatal incarceration. Interviews were conducted via Webex phone or video. The interviews followed a scripted interview guide and lasted one hour on average. Interview transcripts were analyzed using the Rigorous and Accelerated Data Reduction technique to produce an overarching thematic framework. Our analysis identified benefits, including the personal advantage of self-expression, helping others and contributing to change, and financial incentives. Risks included stigma and breach of confidentiality, misunderstanding of the distinction between research and advocacy, and limited ability to share their whole experience. Participant-identified benefits of research mirrored those from other marginalized populations, though participant-identified risks were novel and nuanced. Recruitment and consent should move beyond normative research ethics committees protocol language to consider the perspectives of participants.
Heparin promotes the growth of human embryonic stem cells in a defined serum-free medium
A major limitation in developing applications for the use of human embryonic stem cells (HESCs) is our lack of knowledge of their responses to specific cues that control self-renewal, differentiation, and lineage selection. HESCs are most commonly maintained on inactivated mouse embryonic fibroblast feeders in medium supplemented with FCS, or proprietary replacements such as knockout serum-replacement together with FGF-2. These undefined culture conditions hamper analysis of the mechanisms that control HESC behavior. We have now developed a defined serum-free medium, hESF9, for the culture of HESCs on a type I-collagen substrate without feeders. In contrast to other reported media for the culture of HESCs, this medium has a lower osmolarity (292 mosmol/liter), L-ascorbic acid-2-phosphate (0.1 μg/ml), and heparin. Insulin, transferrin, albumin conjugated with oleic acid, and FGF-2 (10 ng/ml) were the only protein components. Further, we found that HESCs would proliferate in the absence of exogenous FGF-2 if heparin was also present. However, their growth was enhanced by the addition of FGF-2 up to 10 ng/ml although higher concentrations were deleterious in the presence of heparin.
Healthcare Use Among Black and White Congenital Heart Disease Medicaid Enrollees
Congenital heart disease (CHD) is the most common birth anomaly in the US. Research shows lost-to-follow-up trends and racial disparities in healthcare use. This study examines racial differences in healthcare use among Medicaid-covered children with CHD. Using 2010–2019 claims data from a pediatric Medicaid Accountable Care Organization, 960 Black and White children with complex CHD and ≥ 3 years of continuous Medicaid coverage were identified. Three cohorts were constructed (starting age: < 1-year-olds, 1–5-year-olds, 6–15-year-olds) and followed for 3 years. Multivariate analysis assessed annual healthcare use (cardiology, primary care, emergency department) by race, adjusting for patient and provider covariates. Overall, 51% of patients had an annual cardiology visit, and 54% had an annual primary care visit. Among the 1–5-year-old cohort, Black children were predicted to be 13% less likely to have an annual cardiology visit compared to their White counterparts ( p  = 0.001). Older Black children were predicted to be more likely to have a primary care visit compared to their White counterparts. Nearly half of Medicaid-enrolled children with complex CHD did not receive recommended cardiology care. Young Black children were less likely to receive an annual cardiac visit, while older Black children were more likely to receive primary care. While the percentage with an annual cardiac visit was low, the majority had seen a cardiologist within the 3-year window, suggesting these children are still receiving cardiology care, if less frequently than recommended. Opportunities exist for cardiology and primary care to collaborate to ensure patients receive timely recommended care.
Adolescents and Young Adults Living with Congenital Heart Disease: Coping, Stress Reactivity, and Emotional Functioning
Living with congenital heart disease (CHD) presents survivors with numerous stressors, which may contribute to emotional problems. This study examined (a) whether coping with CHD-related stress predicts symptoms of depression and anxiety, and (b) whether associations between coping and emotional distress are moderated by involuntary stress reactivity. Adolescents and young adults diagnosed with CHD ( M age  = 26.4) were recruited from pediatric and adult outpatient cardiology clinics. Participants ( N  = 168) completed online self-report measures. Hierarchical multiple regression analyses revealed that secondary control coping (e.g., cognitive restructuring, positive thinking) predicted lower depression and anxiety. Primary control coping (e.g., problem-solving) and stress reactivity (e.g., rumination, emotional numbing) interacted to predict depression and anxiety: the higher individuals were in involuntary stress reactivity, the stronger was the association between primary control coping and lower depression and anxiety. These results can inform clinical efforts to prevent or reduce emotional distress among CHD survivors.
Perceptions About Lactation Consultant Support, Breastfeeding Experiences and Postpartum Psychosocial Outcomes
IntroductionMany women seek lactation consultant support in the postpartum period. Lactation consultant support in community or clinical settings is often assumed to extend breastfeeding duration, improve breastfeeding experiences, and be well-received. Few studies have assessed women’s perceptions of the support they received, nor have perceptions been examined in relationship to breastfeeding outcomes and maternal well-being. Our objective was to characterize the lactation consultant support women received and examine how women’s perceptions about the support related to their breastfeeding outcomes, anxiety and depressive symptoms, and parenting stress.MethodsThis observational, cross-sectional study examined receipt of postpartum lactation consultant support among 210 US women. Perceptions of lactation consultant support were examined in relation to breastfeeding outcomes, anxiety and depressive symptoms, and parenting stress to explore outcomes of negative versus positive lactation consultant support experiences, using linear and proportional hazards regression.ResultsWhile overall perceptions of lactation consultant support were positive for most recipients (71%, n = 98), 29% (n = 40) reported negative perceptions of lactation consultant support. Negative perceptions were associated with lower breastfeeding self-efficacy (β =  − 11.7, 95% CI − 17.3, − 6.0), a less successful breastfeeding experience (β =  − 19.5, CI − 27.8, − 11.3), greater general anxiety (β = 6.5, CI 2.1, 10.9), and shorter total duration of milk production (HR = 0.39, 95% CI 0.18, 0.84). Perceptions were not associated with depressive symptoms or parenting stress.DiscussionFindings highlight the importance of ensuring that postpartum breastfeeding support provided by lactation consultants is perceived as positive by women.
Smoking among adult congenital heart disease survivors in the United States: Prevalence and relationship with illness perceptions
The relationship between smoking and illness perceptions among congenital heart disease (CHD) survivors is unknown. The primary aims of the present study were to compare the smoking prevalence among CHD survivors to a nationally representative U.S. sample and examine the relationship between smoking and illness perceptions. CHD survivors (N = 744) from six U.S. sites participated in the study. The smoking prevalence among CHD survivors (9.3%) was lower than the general population (15.3%). However, 23.3% of CHD survivors with severe functional limitations smoked. Smoking prevalence differed by U.S. region, with a greater proportion of those attending CHD care in the Midwest reporting smoking (11.8%). The illness perception dimensions of Concern and Emotional Response were independently associated with smoking. Differences in illness perceptions enhance our understanding of smoking among CHD survivors and may guide interventions promoting positive health behaviors. The protocol for the study from which the present analyses were conducted was recorded at ClinicalTrials.gov: NCT02150603.
Patient-Reported Outcomes in Adults With Congenital Heart Disease Following Hospitalization (from APPROACH-IS)
In this international study, we (1) compared patient-reported outcomes (PROs) in adults with congenital heart disease (CHD) who had versus had not been hospitalized during the previous 12 month, (2) contrasted PROs in patients who had been hospitalized for cardiac surgery versus nonsurgical reasons, (3) assessed the magnitude of differences between the groups (i.e., effect sizes), and (4) explored differential effect sizes between countries. APPROACH-IS was a cross-sectional, observational study that enrolled 4,028 patients from 15 countries (median age 32 years; 53% females). Self-report questionnaires were administered to measure PROs: health status; anxiety and depression; and quality of life. Overall, 668 patients (17%) had been hospitalized in the previous 12 months. These patients reported poorer outcomes on all PROs, with the exception of anxiety. Patients who underwent cardiac surgery demonstrated a better quality of life compared with those who were hospitalized for nonsurgical reasons. For significant differences, the effect sizes were small, whereas they were negligible in nonsignificant comparisons. Substantial intercountry differences were observed. For various PROs, moderate to large effect sizes were found comparing different countries. In conclusion, adults with CHD who had undergone hospitalization in the previous year had poorer PROs than those who were medically stable. Researchers ought to account for the timing of recruitment when conducting PRO research as hospitalization can impact results.
Perceived Health Mediates Effects of Physical Activity on Quality of Life in Patients With a Fontan Circulation
Patients with a Fontan circulation are at risk of a sedentary lifestyle. Given the direct relationship between physical activity and health, promotion of physical activity has the potential to improve outcomes, including quality of life (QOL). This study aimed to describe self-reported physical activity levels in adult Fontan patients and examine associations between physical activity, perceived health status and QOL. The sample consisted of 177 Fontan patients (Mage = 27.5 ± 7.6 years, 52% male) who reported their physical activity, perceived health status, and QOL as part of the cross-sectional Assessment of Patterns of Patient-Reported Outcomes in Adults with Congenital Heart disease – International Study. Descriptive statistics and univariate analyses of variance with planned contrasts were computed to describe physical activity characteristics. Mediation analyses tested whether perceived health status variables mediated the association between physical activity and QOL. Forty-six percent of patients were sedentary while only 40% met international physical activity guidelines. Higher physical activity was associated with younger age, lower NYHA class, higher perceived general health, and greater QOL. Patients who commuted by walking and engaged in sports reported better perceived health and QOL. Mediation analyses revealed that perceived general health but not NYHA functional class mediated the association between physical activity and QOL (αβ = 0.22, 95% confidence interval = 0.04 to 0.49). In conclusion, Fontan patients likely benefit from regular physical activity, having both higher perceived general health and functional capacity; greater perceived health status may contribute to enhanced QOL. In conclusion, these data support the pivotal role of regular physical activity for Fontan patients.
