Regional adaptation of the education in palliative and end-of-life Care Pediatrics (EPEC-Pediatrics) curriculum in Eurasia.

BACKGROUND: Pediatric palliative care (PPC) is a priority to improve pediatric hematology oncology (PHO) care in Eurasia. However, there are limited regional opportunities for PPC education. We describe the adaptation and implementation of a bilingual end-user Education in Palliative and End-of-Life Care (EPEC)-Pediatrics course for PHO clinicians in Eurasia. METHODS: Due to COVID-19, this course was delivered virtually, consisting of prerecorded, asynchronous lectures, and a bilingual workshop with interactive lectures and small group sessions. A pre-postcourse design was used to evaluate the knowledge acquisition of the participants including their knowledge alignment with World Health Organization (WHO) guidance, ideal timing of palliative care, and comfort in providing palliative care to their patients. Questions were mostly quantitative with multiple choice or Likert scale options, supplemented by free-text responses. RESULTS: A total of 44 (76%) participants from 14 countries completed all components of the course including pre- and postcourse assessments. Participant alignment with WHO guidance improved from 75% in the pre- to 90% in the postcourse assessments (p < 0.001). After participation, 93% felt more confident controlling the suffering of children at the end of life, 91% felt more confident in prescribing opioids and managing pain, and 98% better understood how to hold difficult conversations with patients and families. Most participants (98%) stated that they will change their clinical practice based on the skills and knowledge gained in this course. CONCLUSIONS: We present a successful regional adaptation of the EPEC-Pediatrics curriculum, including novel delivery of course content via a virtual bilingual format. This course resulted in significant improvement in participant attitudes and knowledge of PPC along with an understanding of the ideal timing of palliative care consultation and comfort in providing PPC to children with cancer. We plan to incorporate participant feedback to improve the course and repeat it annually to improve access to high-quality palliative care education for PHO clinicians in Eurasia.

Translating Research to Action: The Development of a Pediatric Palliative Cancer Care Advocacy Tool in Eurasia.

PURPOSE: The Assessing Doctors' Attitudes on Palliative Treatment study was conducted in 11 Eurasian countries to assess physician knowledge of and structural barriers to integration of palliative care into pediatric oncology. After publication, regional collaborators identified the need to disseminate country-specific study results locally and provide policy recommendations to inform stakeholders. METHODS: The Assessing Doctors' Attitudes on Palliative Treatment report was developed with Eurasian and St Jude pediatric palliative care and oncology experts to summarize study findings and deliver country-level data to local stakeholders. In parallel, an assessment was developed to explore how regional collaborators intend to use the report to improve local advocacy and dissemination of research findings. The country report and assessment were translated to English, Russian, and Mongolian. RESULTS: Country-specific two-page reports display study findings on pediatric palliative care education, access to pediatric palliative care services, and barriers to and timing of integration with cancer care, alongside clinical and policy recommendations. These reports were distributed to collaborators in 11 countries. Assessment results (N = 30) demonstrated that regional collaborators planned to distribute the report to institutional and government stakeholders, aiming to increase access to pediatric palliative care services (77%), establish a community-based palliative care network (70%), and increase opportunities for specialization (70%). CONCLUSION: We describe the development of an evidence-based advocacy tool to inform local health and education policy in Eurasia. This summary report of study findings, translated to local languages and adapted to a broader audience, is currently used to advocate for greater access and quality of palliative care for children with cancer. This work may serve as the basis for future dissemination efforts of scientific research.

Organ Growth and Intestinal Functions of Preterm Pigs Fed Low and High Protein Formulas With or Without Supplemental Leucine or Hydroxymethylbutyrate as Growth Promoters.

The goal of enteral nutritional support for infants born preterm or small for gestational age (SGA) is to achieve normal growth and development. Yet, this is difficult to achieve because of intestinal immaturity. Our objective was to determine if birth weight, protein intake, and the growth promoters leucine (10 g/L) or calcium-ß-hydroxy-ß-methylbutryate (HMB; 1.1 g/L) would affect trajectories of intestinal growth and functions and weights of other organs. Preterm pigs were delivered at gestational day 105 (91% of term) and fed for 6 or 7 days isocaloric formulas that differed in protein content (50 g or 100 g protein/L), with and without the growth promoters leucine or HMB. For comparative purposes organ weights were measured within 12 h after delivery for six term pigs of low and six of average birth weights. The responses of intestinal growth and total intestinal brush border membrane carbohydrases to protein level and supplemental leucine were of greater magnitude for preterm pigs of lower birth weight. Forskolin stimulated chloride secretion in the proximal small intestine was lower for pigs fed the low protein milk replacers. Capacities of the entire small intestine to transport glucose (mmol/kg-day) were not responsive to protein level, leucine, or HMB, and did not differ between small and large pigs. Relative organ weights of the small and average weight term pigs were similar, but some differed from those of the preterm pigs suggesting preterm birth and the standards of care used for this study altered the trajectories of development for the intestine and other organs. Although leucine is an effective generalized growth promoter that enhances gut development of small preterm pigs, it does not mitigate compromised neurodevelopment. Our findings using preterm pigs as a relevant preclinical model indicate nutrition support strategies can influence development of some gastrointestinal tract characteristics and the growth of other organs.

Barriers to the early integration of palliative care in pediatric oncology in 11 Eurasian countries.

BACKGROUND: The early integration of palliative care significantly improves quality of life for children with cancer. However, cultural, structural, and socioeconomic barriers can delay the integration of palliative care into cancer care, particularly in low-income and middle-income countries. To date, little is known regarding the timing of and barriers to palliative care integration in Eurasia. METHODS: The Assessing Doctors' Attitudes on Palliative Treatment (ADAPT) survey evaluates physician perceptions regarding palliative care integration into pediatric oncology in Eurasia. This evidence-based survey was adapted to the regional context; iteratively reviewed by US and regional panelists; and piloted in English, Russian, and Mongolian. After distribution to physicians caring for children with cancer, statistical analysis was complemented by qualitative analysis of open-ended responses. RESULTS: A total of 424 physician responses were received from 11 countries in the Eurasian region. Study findings demonstrated wide variability in access to palliative care experts across countries (18%-96%), with the majority of providers (64%) reporting that the initial palliative care consultation typically occurs when curative options are no longer available. Providers desired an earlier initial palliative care consultation than what currently occurs in their setting (P < .001). Primary barriers to timely consultation included limited access to palliative care services and specialists, lack of physician education, and perceived family resistance. CONCLUSIONS: The current study is the first to identify physician perceptions of the delayed timing of palliative care integration into childhood cancer care and associated barriers in Eurasia. These findings will inform the development of targeted interventions to mitigate local structural and cultural barriers to access and facilitate earlier palliative care integration in the region.

A multicountry assessment in Eurasia: Alignment of physician perspectives on palliative care integration in pediatric oncology with World Health Organization guidelines.

BACKGROUND: The World Health Organization (WHO) advocates for early integration of palliative care for all children with life-threatening illness. Provider awareness and misperceptions, however, can impede this imperative. In the Eurasian region, little is known about physician knowledge and perspectives on palliative care. METHODS: The Assessing Doctors' Attitudes on Palliative Treatment survey was developed as an evidence-based and culturally relevant assessment of physician perceptions on palliative care integration into childhood cancer care in Eurasia. Iteratively tested by American and Eurasian palliative care experts, the survey was culturally adapted, translated, and piloted in English, Russian, and Mongolian. The survey was distributed to physicians caring for children with cancer. Fifteen statements were scored in accordance with WHO guidelines to evaluate provider knowledge. The statistical analysis was complemented by a qualitative analysis of open-ended responses. RESULTS: This study received 424 responses from 11 countries in Eurasia. The mean alignment between provider perspectives and WHO recommendations was 70% (range, 7%-100%). Significant independent predictors of higher alignment included country, prior palliative care education, and greater experience with patient death. Respondents primarily described palliative care as end-of-life care and symptom management. Two-thirds of respondents (67%) reported not feeling confident about delivering at least 1 component of palliative care. CONCLUSIONS: This is the first study assessing physician perspectives and knowledge of palliative care in Eurasia and reveals wide variability in alignment with WHO guidelines and limited confidence in providing palliative care. Study findings will inform targeted educational interventions, which must be tailored to the local political, economic, and cultural context.

Early onset of renal oxidative stress in small for gestational age newborn pigs.

OBJECTIVE: Oxidative stress, a common feature in cardiovascular and renal disease is associated with the causes and consequences of fetal growth restriction. Hence, renal redox status is likely an early determinant of morbidity in small-for-gestational-age (SGA) infants. In this study, we examined renal oxidative stress in naturally-farrowed SGA newborn pigs. METHODS: We studied SGA newborn pigs with 52% less body weight and 59% higher brain/liver weight ratio compared with their appropriate-for-gestational-age (AGA) counterparts. RESULTS: The kidneys of the SGA newborn pigs weighed 56% less than the AGA group. The glomerular cross-sectional area was also smaller in the SGA group. SGA newborn pigs exhibited increased renal lipid peroxidation, reduced kidney and urine total antioxidant capacity, and increased renal nitrotyrosine immunostaining. Whereas the protein expression level of NADPH oxidase (NOX)2 was unchanged, NOX4 expression was significantly higher in SGA kidneys. The level of serum potassium was lower, but serum sodium and creatinine were similar in SGA compared with AGA newborn pigs. The serum concentrations of C-reactive protein and NGAL, the biomarkers of inflammation and early acute kidney injury were significantly elevated in the SGA group. CONCLUSION: Early induction of oxidative stress may contribute to the onset of kidney injury in growth-restricted infants.

A Phosphatidylserine Source of Docosahexanoic Acid Improves Neurodevelopment and Survival of Preterm Pigs.

The amount, composition, and sources of nutrition support provided to preterm infants is critical for normal growth and development, and particularly for structural and functional neurodevelopment. Although omega-3 long chain polyunsaturated fatty acids (LC-PUFA), and particularly docosahexanoic acid (DHA), are considered of particular importance, results from clinical trials with preterm infants have been inconclusive because of ethical limitations and confounding variables. A translational large animal model is needed to understand the structural and functional responses to DHA. Neurodevelopment of preterm pigs was evaluated in response to feeding formulas to term-equivalent age supplemented with DHA attached to phosphatidylserine (PS-DHA) or sunflower oil as the placebo. Newborn term pigs were used as a control for normal in utero neurodevelopment. Supplementing formula with PS-DHA increased weight of the brain, and particularly the cerebellum, at term-equivalent age compared with placebo preterm pigs (P's < 0.10 and 0.05 respectively), with a higher degree of myelination in all regions of the brain examined (all p < 0.06). Brains of pigs provided PS-DHA were similar in weight to newborn term pigs. Event-related brain potentials and performance in a novel object recognition test indicated the PS-DHA supplement accelerated development of sensory pathways and recognition memory compared with placebo preterm pigs. The PS-DHA did not increase weight gain, but was associated with higher survival. The benefits of PS-DHA include improving neurodevelopment and possibly improvement of survival, and justify further studies to define dose-response relations, compare benefits associated with other sources of DHA, and understand the mechanisms underlying the benefits and influences on the development of other tissues and organ systems.
