Extracellular Perinexal Separation Is a Principal Determinant of Cardiac Conduction.

BACKGROUND: Cardiac conduction is understood to occur through gap junctions. Recent evidence supports ephaptic coupling as another mechanism of electrical communication in the heart. Conduction via gap junctions predicts a direct relationship between conduction velocity (CV) and bulk extracellular resistance. By contrast, ephaptic theory is premised on the existence of a biphasic relationship between CV and the volume of specialized extracellular clefts within intercalated discs such as the perinexus. Our objective was to determine the relationship between ventricular CV and structural changes to micro- and nanoscale extracellular spaces. METHODS: Conduction and Cx43 (connexin43) protein expression were quantified from optically mapped guinea pig whole-heart preparations perfused with the osmotic agents albumin, mannitol, dextran 70 kDa, or dextran 2 MDa. Peak sodium current was quantified in isolated guinea pig ventricular myocytes. Extracellular resistance was quantified by impedance spectroscopy. Intercellular communication was assessed in a heterologous expression system with fluorescence recovery after photobleaching. Perinexal width was quantified from transmission electron micrographs. RESULTS: CV primarily in the transverse direction of propagation was significantly reduced by mannitol and increased by albumin and both dextrans. The combination of albumin and dextran 70 kDa decreased CV relative to albumin alone. Extracellular resistance was reduced by mannitol, unchanged by albumin, and increased by both dextrans. Cx43 expression and conductance and peak sodium currents were not significantly altered by the osmotic agents. In response to osmotic agents, perinexal width, in order of narrowest to widest, was albumin with dextran 70 kDa; albumin or dextran 2 MDa; dextran 70 kDa or no osmotic agent, and mannitol. When compared in the same order, CV was biphasically related to perinexal width. CONCLUSIONS: Cardiac conduction does not correlate with extracellular resistance but is biphasically related to perinexal separation, providing evidence that the relationship between CV and extracellular volume is determined by ephaptic mechanisms under conditions of normal gap junctional coupling.

Creation and validation of a NOVA scored picture set to evaluate ultra-processed foods.

There has been a rapid shift in the modern food environment towards increased processing in foods consumed in the United States (US) and globally. The NOVA system (not an acronym) for classifying food on degree of processing currently has the most empirical support. Consumption of foods in the NOVA 4 category, ultra-processed foods (UPF), is a risk factor for a host of poor health outcomes including heart disease, stroke, and cancer. Despite these poor health outcomes, UPF make up 58% of calories consumed in the US. Methodologies for assessing the reinforcing and rewarding properties of these foods are necessary tools. The Becker-DeGroot-Marschak auction paradigm (BDM) is a well validated tool for measuring value and is amenable to neuromonitoring environments. To allow for the testing of hypotheses based on level of food processing, we present a picture set of 14 UPF and 14 minimally-processed foods (MPF) matched on visual properties, food characteristics (fat, carbohydrate, cost, etc.), and rated perceptual properties. Further, we report our scoring of these foods using the NOVA classification system and provide additional data from credentialed nutrition professionals and on inter-rater reliability using NOVA, a critique of the system. Finally, we provide all pictures, data, and code used to create this picture set as a tool for researchers.

Safety and feasibility of destination care for bariatric surgery: a single institution retrospective study.

INTRODUCTION: Increasing emphasis on value-based healthcare has prompted both employers and healthcare organizations to develop innovative strategies to supply high quality care to patients. One such strategy is through the bundled care payment model (BCPM). Through this model, our institution partnered with employers from across the country to provide quality care for their members. Patients traveling greater than 2 h driving time from the bariatric center were considered "destination" patients. To properly care for our destination patients, our institution created a "destination bariatric program." We sought to investigate comparative outcomes for the first 100 patients who completed the program. We hypothesized that there would be no difference in patient outcomes or complications between destination and local patient groups undergoing sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB). METHODS AND PROCEDURES: A retrospective cohort analysis of patients undergoing bariatric surgery at a MBSAQIP-accredited bariatric surgery center between May 2019 and October 2021 was conducted. Patients were divided into destination or local patient groups based on participation in the established destination surgery program. Patient demographics, perioperative clinical outcomes, and complications were compared and statistically analyzed using two-sample t-tests, Chi-square tests, Fisher's exact tests, and univariate logistic regressions. RESULTS: This study identified 296 patients, which consisted of destination (n = 110) and local (n = 186) patient cohorts. Patients in the destination group had higher rates of diabetes mellitus (29.1% vs 24.2%, p = 0.029), but otherwise cohorts had similar basic demographics and comorbidities. Outcomes revealed no statistically significant associations between patient cohort (destination versus local) and ED admission (p = 0.305), hospital readmission (p = 0.893), surgical reintervention (p = 0.974), endoscopic-reintervention (p = 0.714), and patient complications in the postoperative period (30 days). CONCLUSION: Participation in destination care programs for bariatric surgery was found to be both safe and feasible. These destination programs represent an opportunity to provide a broader patient population access to complex surgical care.

National assessment of obstetrics and gynecology and family medicine residents' experiences with CenteringPregnancy group prenatal care.

OBJECTIVE: To examine family medicine (FM) and obstetrician-gynecologist (OB/GYN) residents' experiences with CenteringPregnancy (CP) group prenatal care (GPNC) as a correlate to perceived likelihood of implementing CP in future practice, as well as knowledge, level of support, and perceived barriers to implementation. METHODS: We conducted a repeated cross-sectional study annually from 2017 to 2019 with FM and OB/GYN residents from residency programs in the United States licensed to operate CP. We applied adjusted logistic regression models to identify predictors of intentions to engage with CP in future practice. RESULTS: Of 212 FM and 176 OB/GYN residents included in analysis, 67.01% of respondents intended to participate as a facilitator in CP in future practice and 51.80% of respondents were willing to talk to decision makers about establishing CP. Both FM and OB/GYN residents who spent more than 15 h engaged with CP and who expressed support towards CP were more likely to participate as a facilitator. FM residents who received residency-based training on CP and who were more familiar with CP reported higher intention to participate as a facilitator, while OB/GYN residents who had higher levels of engagement with CP were more likely to report an intention to participate as a facilitator. CONCLUSION: Engagement with and support towards CP during residency are key factors in residents' intention to practice CP in the future. To encourage future adoption of CP among residents, consider maximizing resident engagement with the model in hours of exposure and level of engagement, including hosting residency-based trainings on CP for FM residents.

Predictors of Mortality and Revision Following Digital Amputation for Infection and Necrosis.

PURPOSE: Digital amputation is a commonly performed procedure for infection and necrosis in patients with diabetes, peripheral vascular disease (PVD), and on dialysis. There is a lack of data regarding prognosis for revision amputation and mortality following digital amputation in these patients. METHODS: All digital amputations over 10-year period (2008-2018) at a single center were reviewed. There were 484 amputations in 360 patients, among which 358 were performed for trauma (reference sample) and 126 for infection or necrosis (sample of interest). Patient death and revision were determined from National Vital Statistics System and medical records. Propensity score matching was performed to compare groups. Data were then compared to the Social Security Administration Actuarial Life Table for 2015 to determine age-matched expected mortality. RESULTS: The 2-year revision rate was 34% for amputations performed for infection or necrosis, compared to 15% for amputations due to trauma. For amputations performed for infection or necrosis, the revision rate was 47.7% when diabetes, PVD, and dialysis were present. Among all patients with infection or necrosis (n = 104) undergoing a digital amputation, overall survival at 2, 5, and 10 years was 79.4%, 57.3%, and 17.5%, respectively, which represented a 3.2-fold increased risk of death compared to controls. (hazard ratio, 3.19; 95% confidence interval, 1.47-6.93). For amputations due to trauma, mortality was no different from that in the age-matched general population. CONCLUSIONS: Mortality and revision risk are high for patients requiring a digital amputation for infection or necrosis and are further increased with medical comorbidities. Hand surgeons should consider the prognostic implications of these data when counseling patients. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.

Understanding the mediated relationship between moral distress, depression, and suicide risk in undergraduate nursing students.

BACKGROUND: Nursing students are at higher risk for depression, suicide, and other mental health concerns as compared to the general college student population. Moral distress and other ethical issues may be a significant source of psychological harm within nursing student experiences and warrants further attention. PURPOSE: The purpose of this study was to understand the mediating effect of depression on the relationship between moral distress and suicide risk among undergraduate nursing students. METHODS: This cross-sectional analysis was derived from a larger sequential mixed methods study. The first phase was an online survey completed by a national sample of N = 679 nursing students in the United States. FINDINGS: The relationship between moral distress and suicide risk was fully mediated by depression and statistically significant at the alpha = 0.05 level. CONCLUSION: All three psychological variables (depression, moral distress, suicide risk) impact nursing students and require innovative solutions within nursing and educational programs.

Caregiver Engagement Enhances Outcomes Among Randomized Control Trials of Transitional Care Interventions: A Systematic Review and Meta-analysis.

BACKGROUND: Fluctuations in health among chronically ill adults result in frequent health care transitions. Some interventions to improve patient outcomes after hospitalization include caregiver engagement as a core component, yet there is unclear evidence of the effects of this component on outcomes. OBJECTIVE: The objective of this study was to synthesize evidence regarding the attention given to caregiver engagement in randomized control trials of transitional care interventions (TCIs), estimate the overall intervention effects, and assess caregiver engagement as a moderator of intervention effects. METHODS: Three databases were systematically searched for randomized control trials of TCIs targeting adults living with physical or emotional chronic diseases. For the meta-analysis, overall effects were computed using the relative risk (RR) effect size and inverse variance weighting. RESULTS: Fifty-four studies met criteria, representing 31,291 participants and 66 rehospitalizations effect sizes. Half (51%) the interventions lacked focus on caregiver engagement. The overall effect of TCIs on all-cause rehospitalizations was nonsignificant at 1 month (P=0.107, k=29), but significant at ≥2 months [RR=0.89; 95% confidence interval (CI): 0.82, 0.97; P=0.007, k=27]. Caregiver engagement moderated intervention effects (P=0.05), where interventions with caregiver engagement reduced rehospitalizations (RR=0.83; 95% CI: 0.75, 0.92; P=0.001), and those without, did not (RR=0.97; 95% CI: 0.87, 1.08; P=0.550). Interventions with and without caregiver engagement did not differ in the average number of components utilized, however, interventions with caregiver engagement more commonly employed baseline needs assessments (P=0.032), discharge planning (P=0.006), and service coordination (P=0.035). DISCUSSION: Future TCIs must consistently incorporate the active participation of caregivers in design, delivery, and evaluation.

Predictive Capability of Metabolic Panels for Postoperative Atrial Fibrillation in Cardiac Surgery Patients.

INTRODUCTION: Postoperative atrial fibrillation (POAF) occurs in up to 65% of cardiac surgery patients and is associated with an increased risk for stroke and mortality. Electrolyte disturbances in sodium (Na+), potassium (K+), total calcium (Ca2+), chloride (Cl-), and magnesium (Mg2+) are predisposing factors for POAF, but these imbalances are yet to be used to predict POAF. The purpose of this study is to determine whether the development of POAF can be predicted by blood plasma ionic composition. METHODS: Metabolic panels of patients with no prior history of atrial fibrillation who did (n = 763) and did not develop POAF (n = 2144) after cardiac surgery were obtained from the Carilion Clinic electronic medical record system. We initially evaluated serum Na+, K+, Ca2+, Cl-, and Mg2+ in the two groups using descriptive statistics via scatter and spaghetti plots and then with predictive modeling via logistic regression and random forest models. RESULTS: Neither scatter nor spaghetti plots of electrolyte data revealed a significant difference between those who did and did not develop POAF. Two logistic regression models and two random forest models with POAF status as the outcome were generated using the first observation for each electrolyte and the coefficient of the linear regression, which was obtained from a linear fit of the scatter plot. The random forest model using the first observation had a sensitivity of only 12.2%, but all four models had specificities more than 97%. CONCLUSIONS: Neither of the two logistic regression nor two random forest models were able to effectively predict the development of POAF from plasma ionic concentrations, but the random forest models effectively classified patients who would not develop POAF.

Maternal parenting stress changes over the first year of life in infants with complex cardiac defects and in healthy infants.

OBJECTIVES: Parents of infants with CHDs experience increased parenting stress compared to the general population, potentially interfering with parenting practices and bear adverse family outcomes. The changes in stress over the critical period of infancy have yet to be studied. The current study aimed to compare parenting stress changes over time between parents of infants with CHDs and parents of healthy infants during the first year of infants' life. METHODS: Data from a larger prospective cohort study were longitudinally analysed using mixed-effects multivariable regression modelling. Sample included mothers of 129 infants with complex cardiac defects and healthy infants, recruited from the cardiac ICU of a large cardiac centre and outpatient paediatric practices in Northeastern America. Outcome was measured over four visits via the Parenting Stress Index Long Form. RESULTS: Stress in the cardiac group has significantly decreased over time on the Parent Domain (p = 0.025), and stress in the healthy group has significantly increased over time on the Child Domain (p = 0.033). Parenting stress trajectories demonstrated significant differences between groups on the Parent Domain (p = 0.026) and on the Total Stress (p = 0.039) subscales. CONCLUSIONS: Parenting stress in the paediatric cardiac population changes over time and differs from stress experienced by parents of healthy infants. Findings highlight stressful periods that may be potentially risky for parents of infants with CHDs and introduce additional illness-related and psychosocial/familial aspects to the parenting stress concept.

Medical Complexity Mediates Healthcare Resource Use in the Socially Vulnerable.

GOAL: The objective of this retrospective, observational study was to assess the mediating effect of medical complexity on the relationship between social vulnerability and four acute care resource use outcomes-number of hospitalizations, emergency department (ED) visits, observation stays, and total visits. Such information may help healthcare managers better anticipate the effects of interventions targeted to the socially vulnerable in their patient population. METHODS: Electronic health records of 147,496 adults served by 27 primary care practices in one large health system from 2015 to 2017 were used. Descriptive statistics were applied to characterize patients and the primary care practices included in the study. Causal mediation analyses using a modified Baron and Kenny approach were performed. PRINCIPAL FINDINGS: Causal mediation analyses demonstrated that increased social vulnerability was associated with increased medical complexity (incidence rate ratio [IRR] = 1.57) and increased numbers of hospitalizations (IRR = 1.63), ED visits (IRR = 2.14), observation stays (IRR = 1.94), and total visits (IRR = 2.04). Effects remained significant, though attenuated, after adjusting for medical complexity (mediator), demographics, and medications (hospitalizations IRR = 1.44, ED visits IRR = 2.02, observation stays IRR = 1.74, total visits IRR = 1.86). Social vulnerability, given medical complexity, explained between 8% (ED visits) and 26% (hospitalizations) of the variation in outcomes. PRACTICAL APPLICATIONS: These findings reinforce the need to modify interventions for medically complex adults to address their social needs and, consequently, reduce costly health services. Health systems seeking to reduce costly care can use these results to estimate savings in the treatment of patients with high social vulnerability-before they get chronic conditions and later as they seek care.

Older Adult and Family Caregiver Perspectives on Engagement in Primary Care.

The purpose of the current in-depth qualitative study was to explore the experiences of older adults and family caregivers in primary care. Twenty patients and caregivers from six Comprehensive Primary Care Plus (CPC+) practices' Patient and Family Advisory Councils within a large academic health system participated in telephone interviews from December 2018 to May 2019. Participants were mostly women (60%), with an average age of 71 years and nine chronic conditions. Transcripts were coded using conventional content analysis. Two key themes emerged related to person-centered care (PCC): Engagement in Health Care and Patient-Provider Relationship. Engagement in health care was defined by participants as: being proactive, centering on patient goals in treatment discussions, adherence, and self-triaging. Approximately all participants discussed the importance of the relationship and interactions with their provider as influencing their engagement. The identified themes offer recommendations for further improvement of primary PCC. [Journal of Gerontological Nursing, 48(11), 7-13.].

The conduction velocity-potassium relationship in the heart is modulated by sodium and calcium.

The relationship between cardiac conduction velocity (CV) and extracellular potassium (K+) is biphasic, with modest hyperkalemia increasing CV and severe hyperkalemia slowing CV. Recent studies from our group suggest that elevating extracellular sodium (Na+) and calcium (Ca2+) can enhance CV by an extracellular pathway parallel to gap junctional coupling (GJC) called ephaptic coupling that can occur in the gap junction adjacent perinexus. However, it remains unknown whether these same interventions modulate CV as a function of K+. We hypothesize that Na+, Ca2+, and GJC can attenuate conduction slowing consequent to severe hyperkalemia. Elevating Ca2+ from 1.25 to 2.00 mM significantly narrowed perinexal width measured by transmission electron microscopy. Optically mapped, Langendorff-perfused guinea pig hearts perfused with increasing K+ revealed the expected biphasic CV-K+ relationship during perfusion with different Na+ and Ca2+ concentrations. Neither elevating Na+ nor Ca2+ alone consistently modulated the positive slope of CV-K+ or conduction slowing at 10-mM K+; however, combined Na+ and Ca2+ elevation significantly mitigated conduction slowing at 10-mM K+. Pharmacologic GJC inhibition with 30-µM carbenoxolone slowed CV without changing the shape of CV-K+ curves. A computational model of CV predicted that elevating Na+ and narrowing clefts between myocytes, as occur with perinexal narrowing, reduces the positive and negative slopes of the CV-K+ relationship but do not support a primary role of GJC or sodium channel conductance. These data demonstrate that combinatorial effects of Na+ and Ca2+ differentially modulate conduction during hyperkalemia, and enhancing determinants of ephaptic coupling may attenuate conduction changes in a variety of physiologic conditions.

Parental Post-traumatic Stress and Healthcare Use in Infants with Complex Cardiac Defects.

OBJECTIVE: To examine the associations between post-traumatic stress of parents of infants with complex congenital heart defects and their healthcare use for their infants during the early months of life. STUDY DESIGN: The current study is a secondary data analysis from a randomized controlled trial in which 216 parent-infant dyads were recruited from 3 cardiac intensive care units of large pediatric centers in Northeastern America. The current sample included 153 dyads with post-traumatic stress data at hospital discharge and at 4-months' follow-up. Poisson regressions were used to estimate the effect of post-traumatic stress change scores on number of emergency department (ED) visits, unscheduled cardiologist visits, and unscheduled pediatrician visits outcomes. RESULTS: Infants whose parents gained post-traumatic stress disorder over the study period were at increased risk for ED visits and unscheduled cardiologist visits. Increased symptom severity predicted more unscheduled cardiologist visits and more unscheduled pediatrician visits. Increased symptom clusters (avoidance, arousal, re-experiencing) predicted more ED visits, more unscheduled cardiologist visits, and more unscheduled pediatrician visits. CONCLUSIONS: Parents of infants with cardiac conditions may experience post-traumatic stress following cardiac surgery, which can be linked to greater healthcare use. Findings highlight the importance of screening and treating post-traumatic stress to preserve parental mental health and prevent adverse outcomes.

The disclosure slide-Informative or obligatory, 5 years of SSO Cancer Symposium oral presentations.

BACKGROUND: Financial disclosure (FD) highlights potential conflicts of interest but is often overlooked at academic conferences. METHODS: Retrospective review of 2015-2019 Society of Surgical Oncology Cancer Symposium oral presentation slide and/or verbal FD frequency, duration, and content. RESULTS: Of 963 presentations, 331 (34%) omitted disclosure slide/verbalization. 575 (60%) included a slide, 551 (57%) gave verbal disclosure and 133 (14%) stated relevance. 164 presentations (17%) cited 1 + FD. 2019 had greater median FDs/talk than 2015-2018 (3.50 vs. 2.00; p = .010). Compared to 2015-2018, 2019 yielded shorter median slide display of all disclosures (2.00 s vs. 2.47 s; p = .006), median 1 + FD display (3.37 s vs. 4.81 s; p = .04) and median 1 + FD verbalization (2.81 s vs. 3.66 s; p = .54). 2019 all disclosure verbalization increased (1.97 s vs. 1.14 s; p < .001). Multivariable modeling showed longer display with 2015-2018 (+1.3 s, 95% confidence interval [CI] -0.06 to 2.5 s, p = .04), <4 authors (+3.2 s, 95% CI: 2.1-4.3 s; p < .001) and longer verbalization with 2019 (+0.8 s, 95% CI: 0.2-1.4 s; p = .01), relevance (+1.0 s, 95% CI: 0.4-1.6 s; p = .002), ≤ 4 authors (+0.8 s, 95% CI: 0.3-1.3 s, p < .001) and noncommercial FD (+3.8 s, 95% CI: 2.0-5.0 s; p < .001). The five most cited commercial entities were in 39% of talks. CONCLUSION: Presenters' FDs were brief or omitted. Despite FD increase, disclosure time decreased. Improved FD attention will highlight potential COIs.

Results from Project GOLD: A pilot randomized controlled trial of a psychoeducational HIV/STI prevention intervention for black youth.

Black youth face significant disparities in HIV/sexually transmitted infection (STI) disease burden. Mental illness and emotion regulation are ontributors to HIV/STI risk, yet many HIV/STI prevention interventions do not address these factors. Project GOLD was a pilot randomized controlled trial of a psychoeducational HIV/STI prevention intervention designed to address the role of mental illness and emotion regulation in HIV/STI risk among heterosexually active Black youth aged 14-17 (N = 108). Participants were recruited from outpatient mental health treatment programs and general community settings via community partner referrals, face-to-face encounters, flyers and social media. Assessments were conducted pretest, immediate posttest, and at 3-, 6-, and 12-month follow-up. Although there were no statistically significant differences in behavior change from baseline, there were practically significant effect sizes among HIV condition participants when compared to the general health condition (e.g., fewer sexual partners at 6 months). An increase in theoretical mediators (e.g., condom use negotiation beliefs) was sustained at 12 months. HIV condition participants also reported lower depressive symptom severity, with statistical significance noted at immediate post and at 3 months. The findings highlight the importance and challenges of engaging Black youth in culturally and contextually relevant, developmentally and psychologically appropriate HIV/STI prevention interventions.

Predictors of change over time in subjective daytime sleepiness among older adult recipients of long-term services and supports.

OBJECTIVES: Daytime sleepiness is associated with multiple negative outcomes in older adults receiving long-term services and supports (LTSS) including reduced cognitive performance, need for greater assistance with activities of daily living and decreased social engagement. The purpose of this study was to identify predictors of change in subjective daytime sleepiness among older adults during their first 2 years of receiving LTSS. DESIGN AND SETTING: Secondary analysis of data from a prospective longitudinal study of older adults who received LTSS in their homes, assisted living communities or nursing homes interviewed at baseline and every 3 months for 24 months. PARTICIPANTS: 470 older adults (60 years and older) newly enrolled in LTSS (mean = 81, SD = 8.7; range 60-98; 71% women). MEASUREMENTS: Subjective daytime sleepiness was assessed every 3 months through 2 years using the Epworth Sleepiness Scale. Multiple validated measures were used to capture health-related quality of life characteristics of enrollees and their environment, including symptom status (Symptom Bother Scale), cognition (Mini Mental Status Exam), physical function (Basic Activities of Daily Living), physical and mental general health, quality of life (Dementia Quality of Life, D-QoL), depressive symptoms (Geriatric Depression Scale) and social support (Medical Outcomes Survey-Social Support). RESULTS: Longitudinal mixed effects modeling was used to examine the relationship between independent variables and continuous measure of daytime sleepiness. Increased feelings of belonging, subscale of the D-QoL (effect size = -0.006, 95% CI: -0.013 to -0.0001, p = 0.045) and higher number of depressive symptoms (effect size = -0.002, 95% CI: -0.004 to -0.001, p = 0.001) at baseline were associated with slower rates of increase in daytime sleepiness over time. CONCLUSIONS: Comprehensive baseline and longitudinal screening for changes in daytime sleepiness along with depression and perceived quality of life should be used to inform interventions aimed at reducing daytime sleepiness among older adults receiving LTSS.

Fear of falling in sensory impaired nursing home residents.

Objectives: Fear of falling (FOF) causes excess disability in nursing home (NH) residents and is associated with vision and hearing impairment. We explored factors associated with FOF in 225 NH residents with vision, hearing or dual sensory impairment.Methods: We explored age, gender, cognition, depression, social engagement, illness burden, falls, physical function, mobility, falls self-efficacy and outcome expectancy as predictors of FOF using univariate logistic regression modeling, followed by multivariate analysis by group (visual, hearing, dual, total sample).Results: Fifty-one percent of residents had FOF. Residents who had FOF reported better cognition, lower falls self-efficacy, and higher outcome expectancy in the total sample and in most impairment groups. Falls outcome expectancy predictedFOF in the total sample and in the visual and hearing sensory impairment groups.Conclusion: When addressing FOF in NH residents it is important to address sensory status along with fears about falling to promote function.

The Associations Between Infant Development and Parenting Stress in Infants with Congenital Heart Disease at Six and Twelve Months of Age.

PURPOSE: Developmental delays are among the major morbidities of children with complex congenital heart disease. Parents of infants with complex congenital heart disease experience increased parenting stress levels, which can interfere with parenting processes during infancy. The current study examined associations between infant development and parenting stress in infants with complex congenital heart disease at six and twelve months of age. DESIGN AND METHODS: A secondary analysis of data examined cross-sectional associations between infant's mental and psychomotor development and parenting stress, using general linear regression modeling (N = 75). Data were obtained from a larger prospective cohort study. RESULTS: Mental development was negatively associated with the Parent Domain at six months, and with the Parent Domain and Total Stress at twelve months. Psychomotor development was not significantly associated with parenting stress at six and twelve months. CONCLUSIONS: Parenting stress in parents of infant with complex congenital heart disease may be among the factors shaping the parent-child relationship during the first year of life, which plays an important role in infant development. A potential bidirectional relationship between parenting stress and infant development may fit a transactional model representing the phenomena. PRACTICE IMPLICATIONS: Family interventions aiming to reshape illness perceptions may promote parental adaptive coping and productive parenting practices in populations at risk.

The impact of intimate partner violence, depressive symptoms, alcohol dependence, and perceived stress on 30-year cardiovascular disease risk among young adult women: A multiple mediation analysis.

Intimate partner violence (IPV), the physical, sexual, psychological abuse or control by a former or current intimate partner, affects almost one-third of women in the United States. IPV exposure can result in many negative outcomes including physical injury, increased stress, and depression. Currently, there is a small, but, growing body of literature examining the link between IPV victimization and increased cardiovascular disease (CVD) risk among young adult women. To better prevent this negative outcome, it is imperative to understand what factors associated with IPV victimization may be increasing this risk. A secondary analysis of Wave IV of the Add Health study was conducted to examine possible factors mediating past year IPV exposure and 30-year CVD risk score including perceived stress, depressive symptoms, and alcohol dependence among a representative sample of young adult women in the United States. Multiple mediation analyses were run to examine the possible mediating factors in the relationship between IPV and CVD risk. In a multiple mediation model, the indirect effect of perceived stress became insignificant when depressive symptoms were introduced. The findings of this study reveal that 30-year CVD risk in the context of IPV victimization should continue to be examined among this population. The mediation models suggested the importance of stress and depression in the context of IPV and heart health. Screening for depression among women exposed to IPV should be considered as an important intervention point, not only to mitigate mental health issues, but to also help prevent the development of cardiovascular disease.

Testing the Efficacy of a Web-Based Parent-Adolescent Sexual Communication Intervention Among Puerto Ricans.

This randomized controlled trial tested the efficacy of a Web-based intervention to increase sexual communication between parents and adolescents. Parent/adolescent dyads (n = 660) were recruited from communities in the San Juan area and randomly assigned to the Cuídalos sexual communication or physical activity program. Parent assessments were obtained preintervention and at 3-, 6-, and 12-month follow-up. Parents in the experimental group reported significantly more sexual communication (ie, peer pressure, sexual prevention, protection, risk) over time than parents in the control group. Results support the efficacy of the Cuídalos Web-based format and provide insight into future Web-based sexual health interventions for this population.
