However, central venous catheters (CVCs) are an important risk factor for the development of potentially lethal complications, including catheter related bloodstream infection (CRBSI). We have retrospectively assessed the incidence of CRBSIs in children on long-term PN who were treated at the Children's Hospital Zagreb from January 2011 until January 2019 and the cost effectiveness of the use of taurolidine line locks in children at home PN (HPN). During this period 48 children received long-term PN and 24 children were discharged to HPN. The rate of CRBSI 1.15/1000 catheter days in total; 2.35/1000 days in the hospital and 0.48/1000 days at home. If taurolidine line lock was used every day of PN for children on HPN total costs would exceed existing CRBSI treatment costs more than 5 times.","PeriodicalId":16725,"journal":{"name":"Journal of Pediatric Gastroenterology & Nutrition","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81792962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Koo","doi":"10.1097/MPG.0000000000002550","DOIUrl":"https://doi.org/10.1097/MPG.0000000000002550","url":null,"abstract":"T o the Editor: The position paper by ESPGHAN on palm oil (PO) and beta-palmitate in infant formula (1) shows undisputed biochemical and physiological basis for the negative nutrient absorption effect of palmitic acid from plant-based PO versus that from human or animal fat; and negative clinical effects in animal and tissue models. Use of PO in infant formula results in impaired fat and calcium absorption (2,3), lower growth measurements (4), and bone mass (5). There is uncertainty whether the negative effect on growth and bone accretion persists (1) because 1 cross-sectional follow-up study lacks control for multiple confounders of growth and bone mineralization and a longitudinal follow-up study had only 28% of the original cohort. In an era of evidence-based medicine, it seems prudent to recommend caution with the addition of PO in infant formula, given the multiple potential negative biochemical, physiological, and clinical effects of PO and lack of demonstrated benefits from PO. During infancy, there is a gain of 25 to 30 cm in length and tripling of the bone mass, an amount comparable to the peak bone accretion during adolescence on an annualized basis (6). Since the achievement of optimal peak bone mass throughout childhood and young adulthood is a cornerstone in the prevention of osteoporosis (7), and no guaranteed reversal of the negative effects of PO, it seems prudent to avoid adding PO to infant formula.","PeriodicalId":16725,"journal":{"name":"Journal of Pediatric Gastroenterology & Nutrition","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87583193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We compared macronutrient and energy intakes, growth, diseases associated with prematurity and neurodevelopment in small preterm infants on PN who developed (cases) or did not develop HiTG (controls, CNTR).\u0000\u0000\u0000METHODS\u0000We retrospectively reviewed data of preterm infants with a birth weight (BW) <1250 g consecutively admitted to our NICU (2004-2016) who received routine PN.

We evaluated clinical, serologic, and genetic data to determine risk factors for impaired anthropometrics in Crohn's disease at diagnosis.\u0000\u0000\u0000METHODS\u0000Our study evaluated 772 children newly diagnosed with Crohn's disease, inflammatory phenotype, enrolled in the RISK Stratification Project to determine the factors associated with anthropometric impairment. Data were collected on demographics, growth parameters, disease location, serologic and immunologic markers, and disease severity. We performed a genome-wide association study of genetic polymorphisms associated with inflammatory bowel disease. Regression analysis determined associations between anthropometrics and clinical, serologic, and genetic variables.\u0000\u0000\u0000RESULTS\u0000There were 59 (7%) children with height z-score <-2, 126 (14%) with a weight z-score <-2, and 156 (17%) with a BMI z-score <-2. Linear growth impairment was associated with hypoalbuminemia (p = 0.0052), elevated granulocyte-macrophage colony stimulating factor auto-antibodies (GM-CSF Ab) (p = 0.0110), and elevated CBir antibodies against flagellin (p = 0.0117). Poor weight gain was associated with female gender (p = 0.0401), hypoalbuminemia (p = 0.0162), and thrombocytosis (p = 0.0081). Malnutrition was associated with hypoalbuminemia (p = 0.0061) and thrombocytosis (p = 0.0011). Children with moderate or severe disease had lower weight (p = 0.02 and p = 1.16×10, respectively) and BMI z-scores (p = 2.7 × 10 and p = 1.01 × 10, respectively) than children with quiescent and mild disease. There was no association between age of diagnosis, Tanner stage, or disease location and having impaired anthropometrics. There was no genome-wide association between the genetic polymorphisms and the serologic variables and anthropometric measurements.\u0000\u0000\u0000CONCLUSIONS\u0000This is the largest study evaluating growth in treatment-naïve children with Crohn's disease, inflammatory phenotype. It is the first study to use genome-wide sequencing to assess for genetic determinants of growth impairment. GM-CSF auto-antibodies and CBir antibodies are more likely to be elevated in children with growth impairment. Future investigations should evaluate the relationship between genetic polymorphisms, pathologic immune responses, and the biological pathways regulating growth.","PeriodicalId":16725,"journal":{"name":"Journal of Pediatric Gastroenterology & Nutrition","volume":"96 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78960696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using histology as the gold standard for fibrosis, the computer distinguished no fibrosis and mild fibrosis from moderate-to-severe fibrosis with an impressive area under the curve (AUC) of 0.995. To appreciate the significance of this article and that AUC, it will be helpful to review how far imaging has advanced in the 87 years since Dr Burrill Crohn’s seminal paper. In patients diagnosed with Crohn disease, almost half will develop a fibrotic stricture within 10 years of first receiving their diagnosis, often requiring surgical resection (2). The gold standard for diagnosing fibrosis is the deposition of collagen, detected histologically from full-thickness bowel resection. Due to the submucosal and subserosal location of the collagen deposition, fibrosis may be difficult to appreciate by endoscopic visualization or partial-thickness endoscopic biopsy. By imaging, a fibrotic stricture classically demonstrates 3 anatomic features: luminal narrowing, wall thickening, and prestenotic dilation (3). However, these 3 anatomic features alone are late features and are nonspecific, as active inflammation without fibrosis can have a similar appearance. In Crohn’s original 1932 article, he acknowledged the promise and limitations of anatomic imaging: ‘‘The barium meal, however, when carefully interpreted, gives definite positive findings. ... though only in the late or stenotic stages is the delay striking. The midler degrees of stasis and puddling in the ileal loops may easily be overlooked by any but a careful roentgenologist’’(4). It would be another 50 years before cross-sectional imaging (including computed tomography, magnetic resonance imaging ‘‘MRI,’’ and ultrasound) demonstrated diagnostic superiority compared with the traditional fluoroscopic ‘‘barium meal,’’ or what we would now call a ‘‘small bowel follow through’’(5). However, improvements in anatomic detail would only take diagnostic accuracy so far.
