OBJECTIVE: We compared the effect of cereal-thickened formula or postural therapy on regurgitation and gastroesophageal reflux, weight gain, and gastric emptying in infants. METHODS: We performed a prospective trial in exclusively formula-fed infants 2 to 6 mo of age presenting with regurgitation or vomiting at least three times a day. Infants were randomized into two groups; group A received cereal-thickened formula versus group B who were placed in a postprandial upright position for 90 min and evaluated over an 8-wk period. A 90-min technetium 99m milk scintigraphy was performed before and at the end of the intervention period. RESULTS: Thirty-one infants were included in group A and 32 in group B; at inclusion, there were no anthropometric differences between groups (P = 0.813-0.955). After 4 and 8 wk, the difference in regurgitation frequency per day between groups A and B had become significant (at 4 wk, 2.39 +/- 0.86 for group A versus 2.84 +/- 0.81 for group B, P = 0.039; at 8 wk, 1.61 +/- 0.76 for group A versus 2.38 +/- 0.83 for group B, P < 0.001). The volume ingested per meal was not different between groups after 4 wk, although this parameter showed a larger intake in group A after 8 wk (156.8 +/- 23.5 mL for group A versus 143.4 +/- 25.1 mL for group B, P = 0.035), resulting in a significant difference in mean caloric intake. Gastric emptying after 8 wk showed no significant difference between groups A and B. Group A infants had significantly greater weight gain than did group B infants after 4 wk (636.2 +/- 103.4 g for group A versus 577.4 +/- 102.7 g for group B, P = 0.03) and 8 wk (1261.3 +/- 131.4 g for group A versus 1121.4 +/- 137.2 g for group B, P < 0.001). After 8 wk of intervention, the increase in length was significantly greater in group A than in group B (5.2 +/- 0.6 cm for group A versus 4.7 +/- 0.6 cm for group B, P = 0.032). CONCLUSION: Cereal-thickened formula is significantly more efficacious than postural therapy in decreasing the frequency of regurgitation in regurgitating infants. Treatment of regurgitation with cereal-thickened formula results in an increased caloric intake ( approximately 25%), related to increased gain in weight and length, in comparison with regular formula and positioning therapy.
Species of the necrotrophic fungal pathogen Fusarium that cause head blight and crown rot of cereals including wheat also infect a number of alternative host plants. This raises the prospect of more damaging pathogen strains originating and persisting as highly successful saprophytes on hosts other than wheat. The immediate impact on pathogenic (aggressiveness) and saprophytic (growth rate and fecundity) behaviour of six isolates with low, moderate or high initial aggressiveness was examined in two species of Fusarium after their passage through 10 alternative plant hosts. One passage through alternative hosts significantly reduced the pathogenic fitness of most isolates, but this change was not associated with a concomitant change in their overall saprophytic behaviour. The overall weak association between aggressiveness, fecundity and growth rate both before and after passage through the alternative hosts indicate that pathogenic and saprophytic fitness traits may be independently controlled in both Fusarium species. Thus, there was no trade-off between pathogenic and saprophytic fitness in these necrotrophic plant pathogens.
