In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Question: Context: To assess the effect of six different enteral diets on the gut barrier.', 'Laboratory study.', 'University hospital, Germany.', '70 Specific pathogen free female Crl:CDR BR rats.', 'For 7 days, 6 groups of rats were fed orally with standard chow (n = 15); total parenteral nutrition solution (oral TPN, n = 15); elemental diet (ED, n = 10); nutrient-defined diet (NDD, n = 10); or the NDD supplemented with uracil (NDD+uracil, n = 10), or fibre (NDD+fibre, n = 10).', 'Bacterial translocation to mesenteric lymph nodes, numbers of Gram negative enterobacteria and total aerobic bacteria in the caecum, and intestinal concentrations of secretory IgA.', 'The incidence of bacterial translocation was significantly increased in the groups given oral TPN, ED, NDD, and NDD+uracil compared with the group given chow. Only NDD+fibre resulted in a similar degree of translocation to that in the chow group. All groups in which there was increased translocation had a highly significant overgrowth of aerobic bacteria in the caecum, mainly by Gram negative enteric organisms. The secretory IgA concentration was reduced in the group that had been given oral TPN, and that in the ED and NDD+uracil groups was similar to that in the chow group. NDD and NDD+fibre were associated with higher intestinal concentrations of secretory IgA than chow.\Question: Is fibre an essential ingredient of enteral diets to limit bacterial translocation in rats?

Answer: Fibre-free enteral diets do not protect the gut antimicrobial barrier whatever else is in them. The superiority of early enteral as opposed to parenteral nutrition after injury may, therefore, not be the result of a specific protective effect on the gut barrier. The supplementation of commercial enteral diets with bulk fibre should be tested in clinical trials.

Question: Context: The modern multimodality therapeutic approach to Wilms tumor (WT), combining surgery with radiotherapy and chemotherapy results in high cure rates even for high stage disease. However, the combination of radiotherapy and chemotherapy is associated with severe early and late complications such as neutropenic sepsis, growth retardation and secondary malignancies. Therefore, novel therapeutic strategies, which would decrease the treatment burden, are required. We studied the expression of erbB2 growth factor receptor in WT cells as well as its role as a tumor therapeutic target in an in vivo xenograft model of Wilms tumor.', 'Paraffin embedded pathological samples from 14 different WT cases as well as xenografts derived thereof were immunostained with anti-erbB2 monoclonal antibody. The immunostaining was graded in comparison to a known positive control (breast cancer) and was scored by the intensity of staining (0 to +3) multiplied by the percentage of cells expressing the antigen. The expression of erbB2 in the human WT xenograft was verified also by fluorescence activated cell sorter analysis. In addition, nude mice bearing established subcutaneous human WT xenografts were treated with either 3 intraperitoneal injections of N29 anti-erbB2 monoclonal antibody or irrelevant antibody.', 'All of the authentic human pathological samples, except 1 anaplastic WT as well the WT xenografts (at different stages), expressed erbB2. Expression was also observed in WT metastasis and in tumors which out grew chemotherapy. Systemic administration of anti-erbB2 monoclonal antibody inhibited and even prevented the growth of WT xenograft in vivo.\Question: Is erbB2 a tumor associated antigen and a suitable therapeutic target in Wilms tumor?

Answer: ErbB2 is a tumor associated antigen in WT. Being expressed in almost all tumor stages, our in vivo model suggests that erbB2 may serve as a WT therapeutic target. Further work is needed to establish the role of erbB2 in the disease and its potential use in decreasing current treatment burden.

Question: Context: To determine if adolescents with unilateral hearing loss (UHL) demonstrate worse language skills than their siblings with normal hearing (NH).', 'Case-control study of 12-17-year-old adolescents with UHL (20 cases) compared with sibling controls with NH (13 controls).', "Scores on the oral portion of the Oral and Written Language Scales (OWLS) and the Clinical Evaluation of Language Fundamentals (CELF) were the primary outcome measure. Wechsler's Abbreviated Scales of Intelligence (WASI) scores were also used as an outcome measure.", 'Adolescents with UHL demonstrated worse overall and expressive language scores than controls, (98 vs. 114, P=0.001; 100 vs. 114, P=0.006) and had significantly lower full scale (98 vs. 112, P=0.017), verbal (101 vs. 113, P=0.032), and performance IQ (95 vs. 107, P=0.037).\Question: Is unilateral hearing loss associated with a negative effect on language scores in adolescents?

Answer:
These findings suggest that UHL in adolescents is associated with a negative effect on standardized language scores and IQ. They also demonstrate that the developmental gap between children with UHL and children with NH does not resolve as the children progress into adolescence and may even widen as the children grow older. Therefore, these results strongly encourage implementation of early intervention for children with UHL to prevent speech-language delays. More studies in adolescents are warranted to evaluate educational outcomes.
