Bioactives in Oral Nutritional Supplementation: A Pediatric Point of View.
No full textBackground: Oral nutritional supplements (ONSs) are crucial for supporting the nutritional needs of pediatric populations, particularly those with medical conditions or dietary deficiencies. Bioactive compounds within ONSs play a pivotal role in enhancing health outcomes by exerting various physiological effects beyond basic nutrition. However, the comprehensive understanding of these bioactives in pediatric ONSs remains elusive. Objective: This systematic narrative review aims to critically evaluate the existing literature concerning bioactive compounds present in oral nutritional supplements from a pediatric standpoint, focusing on their types, sources, bioavailability, physiological effects, and clinical implications. Methods: A systematic search was conducted across the major academic databases, including PubMed, Scopus, and Web of Science, employing predefined search terms related to oral nutritional supplements, bioactives, and pediatrics. Studies published between 2013 and 2024 were considered eligible for inclusion. Data extraction and synthesis were performed according to the PRISMA guidelines. Results: The initial search yielded 558 of articles, of which 72 met the inclusion criteria. The included studies encompassed a diverse range of bioactive compounds present in pediatric ONS formulations, including, but not limited to, vitamins, minerals, amino acids, prebiotics, probiotics, and phytonutrients. These bioactives were sourced from various natural and synthetic origins and were found to exert beneficial effects on growth, development, immune function, gastrointestinal health, cognitive function, and overall well-being in pediatric populations. However, variations in bioavailability, dosing, and clinical efficacy were noted across different compounds and formulations. Conclusions: Bioactive compounds in oral nutritional supplements offer promising avenues for addressing the unique nutritional requirements and health challenges faced by pediatric populations. However, further research is warranted to elucidate the optimal composition, dosage, and clinical applications of these bioactives in pediatric ONS formulations. A deeper understanding of these bioactive compounds and their interplay with pediatric health may pave the way for personalized and effective nutritional interventions in pediatric clinical practice

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Antiemetics for children with gastroenteritis: off label but still on clinical practice
No full textAntiemetics are not included for treatment of vomiting associated with acute gastroenteritis (AGE) in children by standard guidelines. We performed a survey to determine antiemetic prescribing rates by Italian pediatricians. A structured questionnaire was distributed at a pediatric national conference. The majority of responders reported prescribing antiemetics for pediatric gastroenteritis. Although there is insufficient evidence to justify their use, the use of antiemetics is widely present among pediatricians
Ritonavir combination therapy restores intestinal function in children with advanced HIV disease
No full textOBJECTIVES: To investigate the intestinal absorptive processes in children with HIV infection before and after treatment with combination therapy that includes ritonavir. To test the hypothesis that combination therapy improves intestinal function.
DESIGN: Intestinal function tests were performed in 10 children with advanced HIV disease at the enrollment and after 3 and 6 months of therapy with ritonavir combined with two HIV reverse transcriptase inhibitors. HIV viral load and CD4 cell counts were also determined; body weight was monitored.
METHODS: The D-xylose absorption test, the steatocrit and the determination of fecal alpha1-antitrypsin concentration were used to evaluate carbohydrate and fat absorption, as well as fecal protein loss. Serum iron levels were measured to indirectly evaluate iron absorption. HIV-1 RNA-polymerase chain reaction (PCR) and immunofluorescence imaging were used to evaluate virologic and immunologic responses.
RESULTS: In all, 9 children had carbohydrate malabsorption, 3 steatorrhea, 2 protein loss, and 7 iron deficiency. Most tests produced normal results after 3 months of therapy, and all abnormalities were abolished 6 months after institution of combination therapy. Mean results of each of four absorption tests were significantly changed on combination therapy. Viral load was progressively reduced and CD4 count was increased, with an inverse relationship. An evident shift of body weight pattern toward catch-up growth was observed in all children.
CONCLUSIONS: Ritonavir combination therapy results in prompt and sustained restoration of intestinal function, which is associated with reduction in viral load, increase in CD4 counts, and gain in body weight
Adherence to antiretroviral therapy in HIV-infected children in Italy
No full textAdherence to antiretroviral therapy is a major problem in children with HIV infection, who depend on parents or foster parents for receiving drugs. During an ongoing investigation on intestinal function in children with symptomatic HIV infection who were treated with zidovudine, blood samples were obtained six hours after the administration of zidovudine as reported by the parents and, again, one and six hours after its administration in the hospital, and drug concentration was measured by radioimmunoassay. Both peak and steady state zidovudine levels were within the expected concentration ranges after administration in the hospital. In contrast, they were below the effective concentration in five of the 10 children that reportedly had received the drug at home by the parents. These data directly show poor compliance with antiretroviral therapy in children. Compliance with antiretroviral therapy should be carefully checked in children and strategies are needed to increase full and permanent adherence with antiretroviral therapy by people in charge to administer drugs to HIV-infected children
