Introduction: Recently, significant interest from families and healthcare providers has arisen to use blenderized tube feedings (BTF). Although many institutions are providing this nutritional option, literature documenting outcomes and safety is lacking. Methods: A retrospective chart review was performed on pediatric patients receiving BTF at Rutgers-Robert Wood Johnson University Hospital between January 2013 and April 2017. Demographic data and dietary information before and after BTF were collected. Reasons for diet initiation, symptoms, and anthropometrics were recorded. Adverse events and outcomes were assessed through physician documentation and relevant medication changes. Results: Thirty-five patients (24 boys) received BTF. Age at initiation of BTF ranged from 1 to 19 years (mean 8.3 +/− 5.8 [SD] years). Length of follow-up ranged from 1 to 45 months (mean 15 +/− 12.2 months). The most common reason for starting BTF was gastroesophageal reflux disease (GERD) (N = 32). Almost all patients were on medications for GERD, constipation, or gastrointestinal dysmotility before starting BTF (N = 33). Majority of patients had improvement in relevant symptoms (N = 20); 13 of 33 patients on gastrointestinal medications were able to wean or stop medication(s). BMI z scores did not differ before and after BTF initiation (P = 0.558). No serious life-threatening adverse events were found. Conclusions: Our data suggest that BTF is a safe dietary intervention that may improve gastrointestinal symptoms in pediatric patients. Further prospective studies are needed to compare safety and efficacy of BTF and commercial formulas in pediatric patients.

Background Recent evaluation of rheumatic heart disease (RHD) mortality demonstrates disproportionate disease burden within the United States. However, there are few contemporary data on US children living with acute rheumatic fever (ARF) and RHD. Methods and Results Twenty‐two US pediatric institutions participated in a 10‐year review (2008–2018) of electronic medical records and echocardiographic databases of children 4 to 17 years diagnosed with ARF/RHD to determine demographics, diagnosis, and management. Geocoding was used to determine a census tract‐based socioeconomic deprivation index. Descriptive statistics of patient characteristics and regression analysis of RHD classification, disease severity, and initial antibiotic prescription according to community deprivation were obtained. Data for 947 cases showed median age at diagnosis of 9 years; 51% and 56% identified as male and non‐White, respectively. Most (89%) had health insurance and were first diagnosed in the United States (82%). Only 13% reported travel to an endemic region before diagnosis. Although 96% of patients were prescribed secondary prophylaxis, only 58% were prescribed intramuscular benzathine penicillin G. Higher deprivation was associated with increasing disease severity (odds ratio, 1.25; 95% CI, 1.08–1.46). Conclusions The majority of recent US cases of ARF and RHD are endemic rather than the result of foreign exposure. Children who live in more deprived communities are at risk for more severe disease. This study demonstrates a need to improve guideline‐based treatment for ARF/RHD with respect to secondary prophylaxis and to increase research efforts to better understand ARF and RHD in the United States.

BackgroundLate-onset cardiovascular complications are of serious concerns for even asymptomatic pediatric cancer survivors (PCS). We investigated whether cardiopulmonary exercise testing (CPET) can delineate the underlying pathophysiology of preclinical cardiovascular abnormalities in PCS. MethodsWe examined CPET data via cycle ergometer in asymptomatic PCS with normal echocardiogram and age-matched controls. Peak and submaximal parameters were analyzed. ResultsFifty-three PCS and 60 controls were studied. Peak oxygen consumption (VO2), peak work rate (WR), and ventilatory anaerobic threshold (VAT) were signi cantly lower in PCS than controls (1.86 ± 0.53 vs. 2.23 ± 0.61 L/min, 125 ± 45 vs. 154 ± 46 watt, and 1.20 ± 0.35 vs. 1.42 ± 0.43 L/min, respectively; all p < 0.01), whereas peak heart rate (HR) and ventilatory e ciency (a slope of minute ventilation over CO2 production or DVE/DVCO2) were comparable. Peak respiratory quotient (RQ) was signi cantly higher in PCS (p = 0.0006). Stroke volume (SV) reserve was decreased in PCS, indicated by simultaneous higher dependency on HR (higher ΔHR/ΔWR) and lower peak oxygen pulse (OP) at the peak exercise. Twelve PCS with high peak RQ (≥ 1.3) revealed lower pVO2 and VAT than the rest of PCS despite higher ventilatory e ciency (lower DVE/DVCO2), suggesting fundamental de ciency in oxygen utilization in some PCS. ConclusionsPoor exercise performance in PCS is mainly attributed to limited stroke volume reserve, but the underlying pathophysiology is multi-factorial. Combined assessment of peak and submaximal CPET parameters provided critical information in delineating underlying exercise physiology of PCS.
