Optimising motor development in the hospitalised infant with CHD: factors contributing to early motor challenges and recommendations for assessment and intervention.

BACKGROUND: Neurodevelopmental challenges are the most prevalent comorbidity associated with a diagnosis of critical CHD, and there is a high incidence of gross and fine motor delays noted in early infancy. The frequency of motor delays in hospitalised infants with critical CHD requires close monitoring from developmental therapies (physical therapists, occupational therapists, and speech-language pathologists) to optimise motor development. Currently, minimal literature defines developmental therapists' role in caring for infants with critical CHD in intensive or acute care hospital units. PURPOSE: This article describes typical infant motor skill development, how the hospital environment and events surrounding early cardiac surgical interventions impact those skills, and how developmental therapists support motor skill acquisition in infants with critical CHD. Recommendations for healthcare professionals and those who provide medical or developmental support in promotion of optimal motor skill development in hospitalised infants with critical CHD are discussed. CONCLUSIONS: Infants with critical CHD requiring neonatal surgical intervention experience interrupted motor skill interactions and developmental trajectories. As part of the interdisciplinary team working in intensive and acute care settings, developmental therapists assess, guide motor intervention, promote optimal motor skill acquisition, and support the infant's overall development.

Long-Term Survival and Causes of Death in Children with Trisomy 21 After Congenital Heart Surgery.

OBJECTIVE: To evaluate long-term transplant-free survival and causes of death in the trisomy 21 (T21) population after surgery for congenital heart disease (CHD) in comparison with patients who are euploidic. STUDY DESIGN: This is a retrospective cohort study from the Pediatric Cardiac Care Consortium, enriched with prospectively collected data from the National Death Index and the Organ Procurement and Transplantation Network for patients with sufficient direct identifiers. Kaplan-Meier survival plots were generated and multivariable Cox proportional hazards models were used to examine risk factors for mortality between patients with T21 and 1:1 matched patients with comparable CHD who are euploidic. RESULTS: A long-term survival analysis was completed for 3376 patients with T21 (75 155 person-years) who met inclusion criteria. The 30-year survival rate for patients with T21 ranged from 92.1% for ventricular septal defect to 65.3% for complex common atrioventricular canal. Of these, 2185 patients with T21 were successfully matched with a patient who was euploidic. After a median follow-up of 22.86 years (IQR, 19.45-27.14 years), 213 deaths occurred in the T21 group (9.7%) compared with 123 (5.6%) in the euploidic comparators. After adjustment for age, sex, era, CHD complexity, and initial palliation, the hazard ratio of CHD-related mortality was 1.34 times higher in patients with T21 (95% CI, 0.92-1.97; P = .127). CONCLUSIONS: CHD-related mortality for patients with T21 after cardiac surgical intervention is comparable with euploidic comparators. Children with T21 require lifelong surveillance for co-occurring conditions associated with their chromosomal abnormality.

Optimism despite profound uncertainty: school and social relationships in adolescents with single ventricle heart disease.

BACKGROUND: Survivors of single ventricle heart disease must cope with the physical, neurodevelopmental, and psychosocial sequelae of their cardiac disease, which may also affect academic achievement and social relationships. The purpose of this study was to qualitatively examine the experiences of school and social relationships in adolescents with single ventricle heart disease. METHODS: A descriptive phenomenological methodology was employed, utilising semi-structured interviews. Demographic and clinical characteristics were obtained via chart review. RESULTS: Fourteen adolescents (aged 14 to 19 years) with single ventricle heart disease participated. Interviews ranged from 25 to 80 minutes in duration. Four themes emerged from the interviews, including "Don't assume": Pervasive ableism; "The elephant in the room": Uncertain future; "Everyone finds something to pick on": Bullying at school; "They know what I have been through": Social support. The overall essence generated from the data was "optimism despite profound uncertainty." CONCLUSIONS: Adolescents with single ventricle heart disease identified physical limitations and school challenges in the face of an uncertain health-related future. Despite physical and psychosocial limitations, most remained optimistic for the future and found activities that were congruent with their abilities. These experiences reflect "optimism despite profound uncertainty."

Complementary Paths to Chagas Disease Elimination: The Impact of Combining Vector Control With Etiological Treatment.

Background: The World Health Organization's 2020 goals for Chagas disease are (1) interrupting vector-borne intradomiciliary transmission and (2) having all infected people under care in endemic countries. Insecticide spraying has proved efficacious for reaching the first goal, but active transmission remains in several regions. For the second, treatment has mostly been restricted to recently infected patients, who comprise only a small proportion of all infected individuals. Methods: We extended our previous dynamic transmission model to simulate a domestic Chagas disease transmission cycle and examined the effects of both vector control and etiological treatment on achieving the operational criterion proposed by the Pan American Health Organization for intradomiciliary, vectorial transmission interruption (ie, <2% seroprevalence in children <5 years of age). Results: Depending on endemicity, an antivectorial intervention that decreases vector density by 90% annually would achieve the transmission interruption criterion in 2-3 years (low endemicity) to >30 years (high endemicity). When this strategy is combined with annual etiological treatment in 10% of the infected human population, the seroprevalence criterion would be achieved, respectively, in 1 and 11 years. Conclusions: Combining highly effective vector control with etiological (trypanocidal) treatment in humans would substantially reduce time to transmission interruption as well as infection incidence and prevalence. However, the success of vector control may depend on prevailing vector species. It will be crucial to improve the coverage of screening programs, the performance of diagnostic tests, the proportion of people treated, and the efficacy of trypanocidal drugs. While screening and access can be incremented as part of strengthening the health systems response, improving diagnostics performance and drug efficacy will require further research.

Development and Psychometric Validation of Capacity Assessment of Prosthetic Performance for the Upper Limb (CAPPFUL).

OBJECTIVES: (1) To develop a performance-based measure for adult upper limb (UL) prosthetic functioning through broad (ie, overall performance) and functional domain-specific (eg, control skills) assessment of commonplace activities; (2) to conduct initial psychometric evaluation of the Capacity Assessment of Prosthetic Performance for the Upper Limb (CAPPFUL). DESIGN: Internal consistency of CAPPFUL and interrater reliability for task, functional domain, and full-scale (sub)scores among 3 independent raters were estimated. Known-group validity was examined comparing scores by amputation level. Convergent validity was assessed between CAPPFUL and 2 hand dexterity or function tests; discriminant validity was assessed against self-reported disability. SETTING: Six prosthetic rehabilitation centers across the United States. PARTICIPANTS: Subjects (N=60) with UL amputation using a prosthesis. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Not applicable. RESULTS: Interrater reliability was excellent for scoring on the task, domain, and full-scale scores (intraclass correlation coefficients=.88-.99). Internal consistency was good (α=.79-.82). Generally, subjects with higher UL amputation levels scored lower (worse) than subjects with lower UL amputation levels. CAPPFUL demonstrated strong correlations with measures of hand dexterity or functioning (rs=-.58 to .72) and moderate correlation with self-reported disability (r=-.35). CONCLUSIONS: CAPPFUL was designed as a versatile, low-burden measure of prosthesis performance for any UL functional prosthetic device type and any UL amputation level. CAPPFUL assesses overall performance and 5 functional performance domains during completion of 11 tasks that require movement in all planes while manipulating everyday objects requiring multiple grasp patterns. Psychometric evaluation indicates good interrater reliability, internal consistency, known-group validity, and convergent and discriminant validity.

Developmentally Supportive Care in Congenital Heart Disease: A Concept Analysis.

THEORETICAL PRINCIPLES: Improved survival of infants and children with congenital heart disease experience has led to recognition that up to half of congenital heart disease survivors also experience developmental delay. Developmentally supportive care is a care model shown in Neonatal Intensive Care Units to be associated with improved outcomes, but developmentally supportive practices with premature infants may not be equally effective in the cardiac population that includes all ages. PHENOMENA ADDRESSED: The purpose of this paper is to present a concept analysis using the Walker and Avant method in order to identify and define characteristics of developmentally supportive care as it may be applied to the population of neonates, infants, and children with congenital heart disease. A theoretical definition of developmentally supportive care is presented. RESEARCH LINKAGES: This concept analysis will provide nurses and allied health professionals with a theoretical basis to implement high quality, family-centered care that meets individual developmental needs in a population at high risk for developmental sequelae. Nursing implications for developmentally supportive care as it applies to infants and children with heart disease are discussed.

Trypanosoma cruzi-Trypanosoma rangeli co-infection ameliorates negative effects of single trypanosome infections in experimentally infected Rhodnius prolixus.

Trypanosoma cruzi, causative agent of Chagas disease, co-infects its triatomine vector with its sister species Trypanosoma rangeli, which shares 60% of its antigens with T. cruzi. Additionally, T. rangeli has been observed to be pathogenic in some of its vector species. Although T. cruzi-T. rangeli co-infections are common, their effect on the vector has rarely been investigated. Therefore, we measured the fitness (survival and reproduction) of triatomine species Rhodnius prolixus infected with just T. cruzi, just T. rangeli, or both T. cruzi and T. rangeli. We found that survival (as estimated by survival probability and hazard ratios) was significantly different between treatments, with the T. cruzi treatment group having lower survival than the co-infected treatment. Reproduction and total fitness estimates in the T. cruzi and T. rangeli treatments were significantly lower than in the co-infected and control groups. The T. cruzi and T. rangeli treatment group fitness estimates were not significantly different from each other. Additionally, co-infected insects appeared to tolerate higher doses of parasites than insects with single-species infections. Our results suggest that T. cruzi-T. rangeli co-infection could ameliorate negative effects of single infections of either parasite on R. prolixus and potentially help it to tolerate higher parasite doses.

Flight behavior and performance of Rhodnius pallescens (Hemiptera: Reduviidae) on a tethered flight mill.

ABSTRACT Flight dispersal of the triatomine bug species Rhodnius pallescens Barber, the principal vector of Chagas disease in Panama, is an important mechanism for spreading Trypanosoma cruzi, causative agent of Chagas disease. This study measures R. pallescens flight performance using a tethered flight mill both when uninfected, and when infected with T. cruzi or Trypanosoma rangeli. Forty-four out of the 48 (91.7%) insects initiated flight across all treatments, and trypanosome infection did not significantly impact flight initiation. Insects from all treatments flew a cumulative distance ranging from 0.5 to 5 km before fatiguing. The median cumulative distance flown before insect fatigue was higher in T. cruzi- and T. rangeli-infected insects than in control insects; however, this difference was not statistically significant. There was a positive relationship between parasite load ingested and time until flight initiation in T. rangeli-infected bugs, and T. rangeli- and T. cruzi-infected females flew significantly faster than males at different time points. These novel findings allow for a better understanding of R. pallescens dispersal ability and peridomestic management strategies for the prevention of Chagas disease in Panama.

First Report of Chagas Disease Vector Species Triatoma sanguisuga (Hemiptera: Reduviidae) Infected with Trypanosoma cruzi in Delaware.

In July and October 2023, two live triatomine bugs were found inside a home in New Castle County, Delaware. The bugs were identified as Triatoma sanguisuga, the most widespread triatomine bug species in the United States. Triatoma sanguisuga is a competent vector of Trypanosoma cruzi, the causative agent of Chagas disease. The two specimens were tested via real-time PCR (qPCR) for infection with T. cruzi, and one of the specimens was positive. Despite T. sanguisuga being endemic to the area, attainment of accurate species identification and T. cruzi testing of the bugs required multiple calls to federal, state, private, and academic institutions over several months. This constitutes the first report of T. sanguisuga infected with T. cruzi in Delaware. In addition, this is the first published report of T. sanguisuga in New Castle County, the northernmost and most densely populated county in Delaware. New Castle County still conforms to the described geographic range of T. sanguisuga, which spans from Texas to the East Coast of the United States. The T. cruzi infection prevalence of the species has not been studied in the northeastern United States, but collections in southern states have found prevalences as high as 60%. The Delaware homeowner's lengthy pursuit of accurate information about the vector highlights the need for more research on this important disease vector in Delaware.

Trisomy 21 and Congenital Heart Disease: Impact on Health and Functional Outcomes From Birth Through Adolescence: A Scientific Statement From the American Heart Association.

Due to improvements in recognition and management of their multisystem disease, the long-term survival of infants, children, and adolescents with trisomy 21 and congenital heart disease now matches children with congenital heart disease and no genetic condition in many scenarios. Although this improved survival is a triumph, individuals with trisomy 21 and congenital heart disease have unique and complex care needs in the domains of physical, developmental, and psychosocial health, which affect functional status and quality of life. Pulmonary hypertension and single ventricle heart disease are 2 known cardiovascular conditions that reduce life expectancy in individuals with trisomy 21. Multisystem involvement with respiratory, endocrine, gastrointestinal, hematological, neurological, and sensory systems can interact with cardiovascular health concerns to amplify adverse effects. Neurodevelopmental, psychological, and functional challenges can also affect quality of life. A highly coordinated interdisciplinary care team model, or medical home, can help address these complex and interactive conditions from infancy through the transition to adult care settings. The purpose of this Scientific Statement is to identify ongoing cardiovascular and multisystem, developmental, and psychosocial health concerns for children with trisomy 21 and congenital heart disease from birth through adolescence and to provide a framework for monitoring and management to optimize quality of life and functional status.

Developmental Care for Hospitalized Infants With Complex Congenital Heart Disease: A Science Advisory From the American Heart Association.

Developmental disorders, disabilities, and delays are a common outcome for individuals with complex congenital heart disease, yet targeting early factors influencing these conditions after birth and during the neonatal hospitalization for cardiac surgery remains a critical need. The purpose of this science advisory is to (1) describe the burden of developmental disorders, disabilities, and delays for infants with complex congenital heart disease, (2) define the potential health and neurodevelopmental benefits of developmental care for infants with complex congenital heart disease, and (3) identify critical gaps in research aimed at evaluating developmental care interventions to improve neurodevelopmental outcomes in complex congenital heart disease. This call to action targets research scientists, clinicians, policymakers, government agencies, advocacy groups, and health care organization leadership to support funding and hospital-based infrastructure for developmental care in the complex congenital heart disease population. Prioritization of research on and implementation of developmental care interventions in this population should be a major focus in the next decade.

Incentivizing optimal risk map use for Triatoma infestans surveillance in urban environments.

In Arequipa, Peru, a large-scale vector control campaign has successfully reduced urban infestations of the Chagas disease vector, Triatoma infestans. In addition to preventing new infections with Trypanosoma cruzi (etiological agent of Chagas disease), the campaign produced a wealth of information about the distribution and density of vector infestations. We used these data to create vector infestation risk maps for the city in order to target the last few remaining infestations, which are unevenly distributed and difficult to pinpoint. Our maps, which are provided on a mobile app, display color-coded, individual house-level estimates of T. infestans infestation risk. Entomologic surveillance personnel can use the maps to select homes to inspect based on estimated risk of infestation, as well as keep track of which parts of a given neighborhood they have inspected to ensure even surveillance throughout the zone. However, the question then becomes, how do we encourage surveillance personnel to actually use these two functionalities of the risk map? As such, we carried out a series of rolling trials to test different incentive schemes designed to encourage the following two behaviors by entomologic surveillance personnel in Arequipa: (i) preferential inspections of homes shown as high risk on the maps, and (ii) even surveillance across the geographical distribution of a given area, which we term, 'spatial coverage.' These two behaviors together constituted what we termed, 'optimal map use.' We found that several incentives resulted in one of the two target behaviors, but just one incentive scheme based on the game of poker resulted in optimal map use. This poker-based incentive structure may be well-suited to improve entomological surveillance activities and other complex multi-objective tasks.

Improved oral health knowledge in a primary care pediatric nurse practitioner program.

ABSTRACT: Pediatric nurse practitioners (PNPs) are a significant workforce in primary care and are uniquely positioned to improve oral health in children through ongoing surveillance in the well-child visit. The purpose of this study was to evaluate PNP student satisfaction and knowledge gained with the integration of the Strategic Partnership for Interprofessional Collaborative Education in Pediatric Dentistry (SPICE-PD) oral health education program into the first-year primary care curriculum. A descriptive, comparative design examined dental test scores across the pre-SPICE-PD (2013-2014; n = 26) and post-SPICE-PD (2015-2020; n = 55) cohorts. An electronic survey was completed (n = 47; 67%), and focus group (n = 12) audio-recordings were analyzed using Atlas.ti 8.0. Chi-square test and independent samples t-test were used to assess differences between groups. The SPICE-PD students reported improved knowledge and skill in clinical practice. Focus group themes were oral health education was beneficial, impact of coronavirus disease 2019, and suggestions for improvement. Mean dental test scores improved pre- and post-SPICE-PD (83 vs. 93; p < .001). The SPICE-PD oral health education improved knowledge and was highly satisfying for students. Pediatric nurse practitioners are ideally positioned to integrate oral health into primary care services, thereby improving access to care and ultimately reducing or mitigating early childhood caries. Evaluation of PNP postgraduation practices in the primary care setting is needed to assess whether improved knowledge results in practice change.

Addressing Social Determinants of Health and Mitigating Health Disparities Across the Lifespan in Congenital Heart Disease: A Scientific Statement From the American Heart Association.

Despite the overall improvement in life expectancy of patients living with congenital heart disease (congenital HD), disparities in morbidity and mortality remain throughout the lifespan. Longstanding systemic inequities, disparities in the social determinants of health, and the inability to obtain quality lifelong care contribute to poorer outcomes. To work toward health equity in populations with congenital HD, we must recognize the existence and strategize the elimination of inequities in overall congenital HD morbidity and mortality, disparate health care access, and overall quality of health services in the context of varying social determinants of health, systemic inequities, and structural racism. This requires critically examining multilevel contributions that continue to facilitate health inequities in the natural history and consequences of congenital HD. In this scientific statement, we focus on population, systemic, institutional, and individual-level contributions to health inequities from prenatal to adult congenital HD care. We review opportunities and strategies for improvement in lifelong congenital HD care based on current public health and scientific evidence, surgical data, experiences from other patient populations, and recognition of implicit bias and microaggressions. Furthermore, we review directions and goals for both quantitative and qualitative research approaches to understanding and mitigating health inequities in congenital HD care. Finally, we assess ways to improve the diversity of the congenital HD workforce as well as ethical guidance on addressing social determinants of health in the context of clinical care and research.

Junctional Ectopic Tachycardia: Recognition and Modern Management Strategies.

Junctional ectopic tachycardia is a common dysrhythmia after congenital heart surgery that is associated with increased perioperative morbidity and mortality. Risk factors for development of junctional ectopic tachycardia include young age (neonatal and infant age groups); hypomagnesemia; higher-complexity surgical procedure, especially near the atrioventricular node or His bundle; and use of exogenous catecholamines such as dopamine and epinephrine. Critical care nurses play a vital role in early recognition of dysrhythmias after congenital heart surgery, assessment of hemodynamics affecting cardiac output, and monitoring the effects of antiarrhythmic therapy. This article reviews the underlying mechanisms of junctional ectopic tachycardia, incidence and risk factors, and treatment options. Currently, amiodarone is the pharmacological treatment of choice, with dexmedetomidine increasingly used because of its anti-arrhythmic properties and sedative effect.

Preliminary Characterization of Triatomine Bug Blood Meals on the Island of Trinidad Reveals Opportunistic Feeding Behavior on Both Human and Animal Hosts.

Chagas disease is a neglected tropical disease caused by infection with Trypanosoma cruzi. The parasite is endemic to the Americas, including the Caribbean, where it is vectored by triatomine bugs. Although Chagas disease is not considered a public health concern in the Caribbean islands, studies in Trinidad have found T. cruzi-seropositive humans and T. cruzi-infected triatomine bugs. However, little is known about triatomine bug host preferences in Trinidad, making it difficult to evaluate local risk of vector-borne T. cruzi transmission to humans. To investigate this question, we collected triatomine bugs in Trinidad and diagnosed each one for T. cruzi infection (microscopy and PCR). We then carried out a blood meal analysis using DNA extracted from each bug (PCR and sequencing). Fifty-five adult bugs (54 Panstrongylus geniculatus and one Rhodnius pictipes) were collected from five of 21 sample sites. All successful collection sites were residential. Forty-six out of the 55 bugs (83.6%) were infected with T. cruzi. Fifty-three blood meal hosts were successfully analyzed (one per bug), which consisted of wild birds (7% of all blood meals), wild mammals (17%), chickens (19%), and humans (57%). Of the 30 bugs with human blood meals, 26 (87%) were from bugs infected with T. cruzi. Although preliminary, our results align with previous work in which P. geniculatus in Trinidad had high levels of T. cruzi infection. Furthermore, our findings suggest that P. geniculatus moves between human and animal environments in Trinidad, feeding opportunistically on a wide range of species. Our findings highlight a critical need for further studies of Chagas disease in Trinidad in order to estimate the public health risk and implement necessary preventative and control measures.

Postoperative and long-term outcomes in children with Trisomy 21 and single ventricle palliation.

OBJECTIVE: Patients with Trisomy 21 (T21) and single ventricle (SV) physiology present unique challenges compared to euploidic counterparts. This study reports postoperative and long-term outcomes in patients with T21 and SV palliation. DESIGN: This retrospective cohort study from the Pediatric Cardiac Care Consortium (PCCC) included patients with T21 (<21 years old) that underwent surgical palliation for SV between 1982 and 2008 and control patients without known genetic anomaly following Fontan palliation for similar diagnoses. Kaplan-Meier survival plots were created based on death events obtained from the PCCC and by linkage with the National Death Index (NDI) and the Organ Procurement and Transplantation Network (OPTN) through 2014 for patients with adequate identifiers. RESULTS: We identified 118 children with T21 who underwent initial surgical SV palliation. Among 90 (75.6%) patients surviving their first surgery, 66 (73.3%) underwent Glenn anastomosis and 25 (27.8%) completed Fontan palliation with in-hospital survival of 80.3% and 76.0%, respectively. Fifty-three patients had sufficient identifiers for PCCC-NDI-OPTN linkage. Ten-year survival, conditioned on discharge alive after the Fontan procedure, was 66.7% compared to 92.2% for 51 controls without genetic anomaly (P = .001). Median age at death for T21 patients following initial surgical SV palliation was 2.69 years (IQR 1.34-7.12) with most deaths (89.2%) attributed to the underlying congenital heart disease (CHD). CONCLUSIONS: Children with T21 and SV are at high risk for procedural and long-term mortality related to their genetic condition and underlying CHD. Nevertheless, a select group of patients can successfully complete Glenn or Fontan palliation, reaching satisfactory long-term survival.

Supporting Optimal Neurodevelopmental Outcomes in Infants and Children With Congenital Heart Disease.

Improved survival has led to increased recognition of developmental delays in infants and children with congenital heart disease. Risk factors for developmental delays in congenital heart disease survivors may not be modifiable; therefore, it is important that lifesaving, high-technology critical care interventions be combined with nursing interventions that are also developmentally supportive. Implementing developmental care in a pediatric cardiac intensive care unit requires change implementation strategies and widespread support from all levels of health care professionals. This manuscript reviews developmentally supportive interventions such as massage, developmentally supportive positioning, kangaroo care, cue-based feeding, effective pain/anxiety management, and procedural preparation and identifies strategies to implement developmentally supportive interventions in the care of infants and children with congenital heart disease. Improving developmental support for these infants and children at high risk for developmental delay may improve their outcomes and help promote family-centered care.
