OBJECTIVE: Differing protocols have been utilized in published studies evaluating exclusive enteral nutrition (EEN) in the management of active pediatric Crohn's disease. This study aimed to ascertain the protocols currently utilized in different pediatric centers around the world and to highlight their similarities and differences.
METHODS: A questionnaire was circulated to individuals at pediatric centers in countries in Europe, North America and Asia–Pacific. Respondents were asked to indicate the number of children treated with EEN at their centers in the previous years and to provide details of their protocol used for administering EEN to these children.
RESULTS: Responses were received from 35 separate centers (42% of those asked). The duration of EEN varied from <6 weeks to >12 weeks, but was most commonly 6 to 8 weeks. Although 23 different formulas were utilized across the centers, most (90%) used polymeric formulas. Flavourings were commonly added to formulas but wide variations existed between centers with the prescription of food and fluids permitted during the EEN period. The reintroduction of food after EEN also varied greatly: the most common recommendations were for an initial low‐fiber diet (26%) or the gradual introduction of food quantity as the formula volume decreased (52%).
CONCLUSIONS: This questionnaire‐based study has shown the wide variations in EEN protocols used in different areas of the world. The development of consistent protocols may enhance the acceptance, efficacy and wider utilization of this therapy.
rFVIIa has an increasingly accepted role in the management of patients with congenital coagulopathies undergoing major surgery. However, randomized trials are required to define the role of rFVIIa as an adjunct to control major hemorrhage in the pediatric cardiac surgical population. Any future work must focus not only on benefits but also on patient safety, particularly, risk of morbid thromboembolic complication.
Recognition of the adverse effects of conventional extracorporeal circulation (CECC) led to the development of alternative technologies and techniques to minimize their impact while maintaining circulation during coronary artery bypass grafting (CABG). Off-pump coronary artery bypass (OPCAB) grafting has become established as one such alternative and more recently minimalized extracorporeal circulation (MECC) circuits have been developed with the aim of providing circulatory support while minimizing the interface between blood and the foreign surfaces of the circuit that initiates the associated adverse effects of CECC. Recently, some authors have suggested that MECC may be an alternative to OPCAB in patients undergoing CABG; the aim of this article is to systematically analyze and compare the impact of CABG with MECC with that of OPCAB, studying the adverse outcomes related to CECC. We performed a systematic search to identify all studies directly comparing OPCAB and MECC. Endpoints were subcategorized into four key areas of interest: length of stay (LOS), hemorrhage, cerebrovascular injury, and 30-day mortality. Random effect modeling techniques were applied to identify differences in outcomes between the two groups. Six studies fulfilled the inclusion criteria, incorporating 2,072 patients of whom 930 underwent OPCAB and 1,142 underwent revascularization supported by MECC. We found no statistically significant difference in hospital or intensive care unit (ICU) LOS, blood loss, mean number of patients transfused, neurocognitive disturbance, or 30-day mortality between the two groups but a trend toward an increased number of cerebrovascular events in the MECC group was observed. The number of studies comparing these alternative techniques for coronary revascularization is small, and there is a lack of high-quality data. Currently, there seems little difference between MECC and OPCAB but larger randomized controlled trials focusing on high-risk patients are required.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
