Safety and Efficacy of a New Swallowable Intragastric Balloon Not Needing Endoscopy: Early Italian Experience.

PURPOSE: The aim of this study was to evaluate the safety and efficacy of a new intragastric balloon (Elipse™ Balloon, Allurion Technologies, Natick, MA USA) not needing endoscopy. MATERIALS AND METHODS: The balloon was swallowed under fluoroscopy in 38 consecutive patients (F/M 28/10, mean age 46.4 ± 10.6 years, mean weight 109.7 ± 21.9 kg, and mean body mass index (BMI) 38.6 ± 6.7 kg/m2). After 4 months, the balloon spontaneously emptied and it was excreted through the digestive tract without upper endoscopy. RESULTS: There were no complications during balloon passage. After 16 weeks, the mean weight loss was 12.7 kg, mean percent excess weight loss was 26%, and mean BMI reduction was 4.2 kg/m2. Total body weight loss was 11.6%. There was a significant reduction in major co-morbidities related to metabolic syndrome: blood pressure (p < 0.02), waist circumference (p < 0.002), triglycerides (p < 0.0001), blood glucose (p < 0.001), and HOMA-IR index (p < 0.001). At the end of the treatment, 37 balloons were naturally excreted in the stool, and one balloon was endoscopically removed. CONCLUSIONS: The results of this study on 38 consecutive patients demonstrate that the Elipse™ Balloon is safe, effective, and very well accepted by patients.

The growth of Streptococcus mutans in different milks for infant feeding.

After birth various bacterial species, mainly streptococci, colonize the oral cavity and are frequently isolated from carious lesions in children. Previous studies suggest that an earlier colonization of a child's mouth by cariogenic organisms might be related to a higher risk of caries. The aim of this study is to assess the influence of different milks for infant feeding on the growth of Streptococcus mutans (SM) colonies. Three human milk samples from three different mothers and five infant formulas were tested. To prepare the bacterial inoculum, SM was grown in Brain Heart Infusion broth for 18 hours at 37°C in microaerophilic atmosphere. The growth of SM was determined immediately after the inoculation of milks (T0) and after 24 hours (T24) of incubation. After 24 hours of incubation (ΔT= CFUs/ml at T24 – CFUs/ml at T0) the bacterial growth changes were different among milks. Among the complementary milks tested, ΔT of formulas supplemented with Lactobacillus reuteri and with Bifidobacterium lactis was lower than those of non-supplemented formula. In conclusion, on the basis of the reduced SM growth in milks supplemented with probiotics, we may speculate that these formulas have a preventive effect on the development of caries in children.
