RESUMO
Nutrition provision for children with heart disease supported with extracorporeal membrane oxygenation (ECMO) involves nuanced decision making. We examined nutrition provision while on ECMO in the CICU and the relationship between energy and protein adequacy and end organ function as assessed by pediatric sequential organ failure assessment (pSOFA) scores in children with heart disease supported with ECMO. Children (≤ 21 years-old) with congenital or acquired heart disease who received ECMO in the cardiac intensive care unit were included. There were 259 ECMO runs in 252 patients over an 8-year study period (2013-2020). Median energy delivery and adequacy were 26.1 [8.4, 45.9] kcal/kg/day and 58.3 [19.8, 94.6]%, respectively. Median protein delivery and adequacy were 0.98 [0.36, 1.64] g/kg/day and 35.7 [13.4, 60.3]%, respectively. pSOFA increased by a median of four points during the ECMO run. Change in pSOFA score was not associated with energy or protein adequacy (p = 0.46 and p = 0.72, respectively). Higher energy and protein adequacy-from parenteral nutrition-correlated with increased hospital-acquired infections (HAIs, p = 0.031 and p = 0.003, respectively). Achieving nutritional adequacy was dependent on the use of parenteral nutrition. Similar clinical outcomes with regard to end organ function but with an increased incidence of HAIs suggests the need to explore the role of optimal enteral nutrition delivery on ECMO.
RESUMO
Background: Phylloquinone is the most abundant form of vitamin K in US diets. Green vegetables are considered the predominant dietary source of phylloquinone. As our food supply diversifies and expands, the food groups that contribute to phylloquinone intake are also changing, which may change absolute intakes. Thus, it is important to identify the contributors to dietary vitamin K estimates to guide recommendations on intakes and food sources.Objective: The purpose of this study was to estimate 1) the amount of phylloquinone consumed in the diet of US adults, 2) to estimate the contribution of different food groups to phylloquinone intake in individuals with a high or low vegetable intake (≥2 or <2 cups vegetables/d), and 3) to characterize the contribution of different mixed dishes to phylloquinone intake.Methods: Usual phylloquinone intake was determined from NHANES 2011-2012 (≥20 y old; 2092 men and 2214 women) and the National Cancer Institute Method by utilizing a complex, stratified, multistage probability-cluster sampling design.Results: On average, 43.0% of men and 62.5% of women met the adequate intake (120 and 90 µg/d, respectively) for phylloquinone, with the lowest self-reported intakes noted among men, especially in the older age groups (51-70 and ≥71 y). Vegetables were the highest contributor to phylloquinone intake, contributing 60.0% in the high-vegetable-intake group and 36.1% in the low-vegetable-intake group. Mixed dishes were the second-highest contributor to phylloquinone intake, contributing 16.0% in the high-vegetable-intake group and 28.0% in the low-vegetable-intake group.Conclusion: Self-reported phylloquinone intakes from updated food composition data applied to NHANES 2011-2012 reveal that fewer men than women are meeting the current adequate intake. Application of current food composition data confirms that vegetables continue to be the primary dietary source of phylloquinone in the US diet. However, mixed dishes and convenience foods have emerged as previously unrecognized but important contributors to phylloquinone intake in the United States, which challenges the assumption that phylloquinone intake is a marker of a healthy diet. These findings emphasize the need for the expansion of food composition databases that consider how mixed dishes are compiled and defined.

Children with congenital heart disease often require admission to the cardiac intensive care unit at some point in their lives, either after elective surgical or catheter-based procedures or during times of acute critical illness. Meeting both the macronutrient and micronutrient needs of children in the cardiac intensive care unit requires complex decision-making when considering gastrointestinal perfusion, vasoactive support, and fluid balance goals. Although nutrition guidelines exist for critically ill children, these cannot always be extrapolated to children with congenital heart disease. Children with congenital heart disease may also suffer unique circumstances, such as chylothoraces, heart failure, and the need for mechanical circulatory support, which greatly impact nutrition delivery. Guidelines for neonates and children with heart disease continue to be developed. We provide a synthesized narrative review of current literature and considerations for nutrition evaluation and management of critically ill children with congenital heart disease.

BACKGROUND: The optimal timing of supplemental parenteral nutrition (PN) use in the pediatric intensive care unit (ICU) is unclear. We aimed to describe patterns of PN use in the ICU and the association between the timing of PN initiation and macronutrient delivery and anthropometry. METHODS: We enrolled patients (aged <18 years) with an ICU stay >3 days were started on PN in the ICU. Initiation within 48 hours of admission was deemed as early, and duration <5 days was deemed as short. We used multivariable analysis to examine the association between PN timing and macronutrient delivery adequacy (percentage of the prescribed target that was actually delivered) and weight-for-age z-score (WAZ) over hospital stay. RESULTS: Ninety-five patients were included. Median (interquartile range [IQR]) time to initiate PN was 4 (1, 6) days, and in 33%, PN was initiated early. Median (IQR) PN duration was 8 (5, 14) days, and in 16.8%, duration was short. Median (IQR) adequacies for total energy and protein delivery were 55% (40, 74) and 72% (44, 81) in the early PN group compared with 29% (3, 50) and 31% (4, 47), respectively, in the late PN group (P < .001). The late PN group had a 0.50-unit greater decline in mean WAZ compared with the early PN group (95% CI, 0.11-0.89; P = .012). CONCLUSION: Late PN initiation was associated with significantly lower adequacy of macronutrient delivery and greater decline in WAZ in critically ill children. The relationship between PN timing patient outcomes must be further examined.

Vitamin K food composition data have historically been limited to plant-based phylloquinone (vitamin K1). The purpose of this study was to expand analysis of vitamin K to animal products and to measure phylloquinone and 10 forms of menaquinones (vitamin K2) in processed and fresh-cut pork products. Nationally representative samples of processed pork products (n = 28) were obtained through USDA's National Food and Nutrition Analysis Program, and fresh pork (six cuts; n = 5 per cut) and bacon (n = 4) were purchased from local retail outlets. All samples were analyzed by high-performance liquid chromatography (phylloquinone and menaquinone-4) and atmospheric-pressure chemical ionization-liquid chromatography-mass spectrometry (menaquinone-5 to menaquinone-13). Although low in phylloquinone (<2.1 ± 0.5 µg of phylloquinone per 100 g), all processed pork products and fresh pork cuts contained menaquinone-4, menaquinone-10, and menaquinone-11 (range: [35.1 ± 11.0]-[534 ± 89.0] µg of menaquinones per 100 g). The total menaquinone contents of processed pork products were correlated with fat contents (r = 0.935). In summary, processed and fresh-cut pork products are a rich dietary source of menaquinones that are currently unaccounted for in assessment of vitamin K in the food supply.

BACKGROUND: Due to advances in the field of oncology, survival rates for children with cancer have improved significantly. However, these childhood cancer survivors are at a higher risk for obesity and cardiovascular diseases and for developing these conditions at an earlier age. OBJECTIVE: In this paper, we describe the rationale, conceptual framework, development process, novel components, and delivery plan of a behavioral intervention program for preventing unhealthy weight gain in survivors of childhood acute lymphoblastic leukemia (ALL). METHODS: A Web-based program, the Healthy Eating and Active Living (HEAL) program, was designed by a multidisciplinary team of researchers who first identified behaviors that are appropriate targets for weight management in childhood ALL survivors and subsequently developed the intervention components, following core behavioral change strategies grounded in social cognitive and self-determination theories. RESULTS: The Web-based HEAL curriculum has 12 weekly self-guided sessions to increase parents' awareness of the potential impact of cancer treatment on weight and lifestyle habits and the importance of weight management in survivors' long-term health. It empowers parents with knowledge and skills on parenting, nutrition, and physical activity to help them facilitate healthy eating and active living soon after the child completes intensive cancer treatment. Based on social cognitive theory, the program is designed to increase behavioral skills (goal-setting, self-monitoring, and problem-solving) and self-efficacy and to provide positive reinforcement to sustain behavioral change. CONCLUSIONS: Lifestyle interventions are a priority for preventing the early onset of obesity and cardiovascular risk factors in childhood cancer survivors. Intervention programs need to meet survivors' targeted behavioral needs, address specific barriers, and capture a sensitive window for behavioral change. In addition, they should be convenient, cost-effective and scalable. Future studies are needed to evaluate the feasibility of introducing weight management early in cancer care and the efficacy of early weight management on survivors' health outcomes.
