Effects of apples and specific apple components on the cecal environment of conventional rats: role of apple pectin

Background  

Our study was part of the large European project ISAFRUIT aiming to reveal the biological explanations for the epidemiologically well-established health effects of fruits. The objective was to identify effects of apple and apple product consumption on the composition of the cecal microbial community in rats, as well as on a number of cecal parameters, which may be influenced by a changed microbiota.     

Usefulness of Fluoxetine in Obese Non-Insulin-Dependent Diabetics: A Multicenter Study

Weight reduction is essential in the management of most noninsulin-dependent diabetics, but this therapeutical goal is difficult to obtain. In this double-blind parallel study, 82 noninsulin-dependent diabetics, moderately obese (BMI = 30–39 kg/nr²), were given for an 8-week period either placebo (P) or fluoxetine (F), a specific serotonin reuptake inhibitor, in addition to their usual antidiabetic treatment. Thirty-nine of them received 60 mg fluoxetine a day and 43 were given the placebo. At admission, both groups had similar weight excess, metabolic control and serum lipid values. In comparison with the P-treated subjects, those treated with fluoxetine (F) lost more weight after 3 weeks (-1.9 vs. ?0.7 kg, p<0.0009) and after 8 weeks (-3.1 vs. ?0.9 kg, p<0.0007). Fasting blood glucose decreased in group F after 3 weeks (- 1.5 vs. ?0.4 mmol/L, p<0.003) and after 8 weeks (-1.7 vs. ?0.02 mmol/L, p<0.0004). HbAlc decreased from 8.5% to 7.7% in group F and from 8.6% to 8.3% in group P (p=0.057). Mean triglyceride level was also reduced in group F after 8 weeks (p=0.042). Fasting C-pep-tide did not change in either group, but fasting insulin values decreased in group F after 3 weeks (p<0.02) and after 8 weeks (p<0.05). The insulin/C-peptide molar ratio decreased significantly in group F after 3 weeks (p<0.04) and after 8 weeks (p<0.05) in comparison with group P. The drug was generally well tolerated and no major side effects were reported. In conclusion, the addition of fluoxetine to the usual oral hypoglycemic agent therapy might be beneficial in obese non-insulin-dependent diabetics, at least on a short-term basis.
