Dose effect of bovine lactoferrin fortification on diarrhea and respiratory tract infections in weaned infants with anemia: A randomized, controlled trial.

OBJECTIVE: The aim of this study was to explore the dose effect of bovine lactoferrin (bLF) fortification on the morbidity of diarrhea and respiratory tract infections in weaned infants with anemia. METHODS: A total of 108 infants with anemia, who were exclusively breast fed at 4 to 6 mo and weaned and formula fed at 6 to 9 mo, were recruited. The eligible infants were randomly assigned to fortified group 0 (FG0), fortified group 1 (FG1), or fortified group 2 (FG2) and were given formula fortified with 0 mg/100 g, 38 mg/100 g, and 76 mg/100 g of bLF, respectively, for 3 mo. The morbidity of diarrhea and respiratory tract infections (RTIs), the duration of respiratory and diarrhea-related illnesses, and the levels of fecal human beta-defensin 2 (HBD-2), cathelicidin LL-37 (LL-37), secretory IgA (sIgA), butyrate, and calprotectin were assessed. RESULTS: After the exclusion of 12 dropouts, the primary outcome measures, including episodes and duration of diarrhea and RTIs during the intervention, were obtained from 96 infants (35, 33, and 28 in FG0, FG1, and FG2, respectively). Compared with infants in FG0, there was a lower morbidity of rhinorrhea, wheezing, and skin rash among infants in FG1 (P < 0.05) and a lower morbidity of respiratory-related illness and wheezing among infants in FG2 (P < 0.05). Furthermore, a lower morbidity of diarrhea-related illness, diarrhea, vomiting, and nausea was observed among infants in FG2 than those in the other two groups (P < 0.05). In addition, the FG1 infants had a lower morbidity of vomiting and nausea than the FG0 infants (P < 0.05). The HBD-2, LL-37, sIgA, and calprotectin levels were significantly higher whereas the butyrate level was significantly lower in the FG2 infants than in infants in the other two groups after 3 mo of intervention (P < 0.05). CONCLUSIONS: The bLF-fortified formula was effective in reducing the morbidity of diarrhea and RTIs in infants with anemia, with the 76 mg/100 g bLF-fortified formula exhibiting a stronger effect. The bLF fortification could be a new strategy for the prevention of diarrhea and RTIs in infants with anemia.

Effectiveness of intervention program on the change of glycaemic control in diabetes with depression patients: A meta-analysis of randomized controlled studies.

AIM: The glycaemic control of diabetes with depression was inconsistent from randomized controlled studies. This meta-analysis aimed to explore the effectiveness of intervention methods in diabetes with depression. METHODS: This study systematically searched electronic databases (PubMed, EBSCO, Elsevier, Springer, Wiley, and Cochrane) for studies published up to August 17, 2020. Standardized mean difference (SMD) and 95%CI were used to evaluate the effectiveness of interventions on HbA1c. Heterogeneity was estimated using the I2 statistic. Begg's test was used to assess the possible publication bias among studies. RESULTS: Twelve studies of 2444 cases were included in this study. The overall SMD is -0.22 and 95%CI -0.33 to -0.10 in 0-6 months of intervention group. The I2 and P were 18.4% and 0.26. There are no publication bias tested (z = 0.37, P = 0.72). CONCLUSION: Cognitive behavioral therapy and mindful self-compassion might be effective method to improve glycaemic control of diabetes with depression in 0-6 months.
