METHODS: This cross-sectional study collected sociodemographic and clinical characteristics, stoma output, and dietary intake upon discharge, hospitalization, and readmission within 30 d of discharge.
RESULTS: A total of 29 participants were recruited, with 72.4% having moderate malnutrition risk. Patients who received partially hydrolyzed guar gum (PHGG) fiber reported lower stoma output with firmer output consistency than patients who received standard care (SC) (P < 0.05 and P < 0.01). Patients who received PHGG achieved higher energy, protein, and soluble fiber intake than did the SC group (P < 0.01) upon discharge. There was a significant inverse association between soluble fiber (PHGG fiber + dietary soluble fiber) intake and ileostomy output (r, -0.494; P = 0.006).
CONCLUSIONS: Partially hydrolyzed guar gum fiber acts as an agent to hold water, reduce the speed of gastrointestinal tract transit, increase effluent viscosity, and potentially decrease water losses. Supplementation with PHGG fiber appeared to minimize ileostomy output and improve clinical outcomes among postoperative ileostomy patients. This needs to be evaluated further with a randomized controlled trial to confirm this preliminary finding.
OBJECTIVE: The main objective of this study is to determine the potential anti-proliferative effect of KGM on cancer and normal human liver cell lines, HepG2 and WRL68, respectively.
METHOD: HepG2 and WRL68 cells were treated with KGM, D-mannose, KGM-D-mannose and 5-fluorouracil. The morphological changes in those treated cells were observed. Cytotoxic effect of the treatments on cell viability and proliferation, and apoptosis genes expression were assessed by cytotoxicity assay, flow cytometry and RT-PCR analyses.
RESULTS: The results show that KGM treatment resulted in reduced viability of HepG2 cells significantly, in line with the apoptosis-like morphological changes. Up-regulation of BAX and down-regulation of BCL2 genes as reflected by high Bax to Bcl 2 ratio suggests that the inhibitory effect of KGM on HepG2 cells most likely via Bcl2/Bax protein pathway. Despite the effectiveness of standard drug 5-FU in suppressing the viability and proliferation of HepG2 cells, it however, exhibited no selective inhibition of cancer cells as compared to KGM.
CONCLUSION: Current findings suggested that KGM is a potential anti-cancer compound/drug entity, which could be an alternative preventive agent against liver cancer.
METHODS: Adult patients undergoing pelvic radiation were recruited and randomly assigned to receive supplementation of either 10 g of PHGG or placebo (maltodextrin) twice daily, 14 days prior and 14 days during pelvic radiation. Diarrhea frequency, fecal samples, nutrition status, and QoL were assessed at baseline and days 14, 28 (2 weeks after pelvic radiation), and 45 (at the completion of pelvic radiation, 2 weeks' postsupplementation).
RESULTS: A total of 30 patients (mean age 56.5 ± 10.8 years, 75% malnourished) participated. The mean of diarrhea frequency in the intervention group (IG) was higher compared with the control group (CG) from days 14 and 28 but reduced at day 45. There was a significant intervention effect after controlling for confounders (ie, baseline diarrhea, age, nutrition status) (P < .05). Bifidobacterium count increased by double among the IG at 14 days of PHGG supplementation, whereas such trend was not observed in the CG.
CONCLUSION: Supplementation of PHGG potentially increased the bifidobacterial count and seemed to have post-supplementation effects by reducing the frequency of diarrhea upon the completion of pelvic radiation treatment.
