    Input: Balanced glucose metabolism ensures optimal fetal growth with long-term health implication s conferred on both mother and child . We examined whether supplementation of probiotics with dietary counselling affects glucose metabolism in normoglycaemic pregnant women . At the first trimester of pregnancy 256 women were r and omised to receive nutrition counselling to modify dietary intake according to current recommendations or as controls ; the dietary intervention group was further r and omised to receive probiotics ( Lactobacillus rhamnosus GG and Bifidobacterium lactis Bb12 ; diet/probiotics ) or placebo ( diet/placebo ) in a double-blind manner , whilst the control group received placebo ( control/placebo ) . Blood glucose concentrations were lowest in the diet/probiotics group during pregnancy ( baseline-adjusted means 4.45 , 4.60 and 4.56 mmol/l in diet/probiotics , diet/placebo and control/placebo , respectively ; P = 0.025 ) and over the 12 months ' postpartum period ( baseline-adjusted means 4.87 , 5.01 and 5.02 mmol/l ; P = 0.025 ) . Better glucose tolerance in the diet/probiotics group was confirmed by a reduced risk of elevated glucose concentration compared with the control/placebo group ( OR 0.31 ( 95 % CI 0.12 , 0.78 ) ; P = 0.013 ) as well as by the lowest insulin concentration ( adjusted means 7.55 , 9.32 and 9.27 mU/l ; P = 0.032 ) and homeostasis model assessment ( adjusted means 1.49 , 1.90 and 1.88 ; P = 0.028 ) and the highest quantitative insulin sensitivity check index ( adjusted means 0.37 , 0.35 and 0.35 ; P = 0.028 ) during the last trimester of pregnancy . The effects observed extended over the 12-month postpartum period . The present study demonstrated that improved blood glucose control can be achieved by dietary counselling with probiotics even in a normoglycaemic population and thus may provide potential novel means for the prophylactic and therapeutic management of glucose disorders To our knowledge , no reports are available indicating the favorable effects of synbiotic bread consumption on blood lipid profiles among patients with type 2 diabetes mellitus ( T2DM ) . This study was conducted to evaluate the effects of the daily consumption of synbiotic bread on blood lipid profiles of patients with T2DM . This r and omized double-blinded controlled clinical trial was performed with 78 diabetic patients , aged 35–70 years . After a 2-week run-in period , subjects were r and omly assigned to consume either synbiotic ( n = 26 ) , probiotic ( n = 26 ) or control bread ( n = 26 ) for 8 weeks . The synbiotic bread contained viable and heat-resistant probiotic Lactobacillus sporogenes ( 1 × 108 CFU ) and 0.07 g inulin ( HPX ) as prebiotic per 1 g. The probiotic bread contained L. sporogenes ( 1 × 108 CFU ) per 1 g. Patients were asked to consume the synbiotic , probiotic and control breads three times a day in a 40 g package for a total of 120 g/day . Biochemical measurements including blood lipid profiles were conducted before and after 8 weeks of intervention . Consumption of the synbiotic bread , compared to the probiotic and control breads , led to a significant decrease in serum TAG ( P = 0.005 ) , VLDL-C ( P = 0.005 ) , TC/HDL-C ( P = 0.002 ) and a significant increase in serum HDL-C levels ( P = 0.01 ) . No significant effect of synbiotic bread consumption on FPG , TC , LDL-C and non-HDL-C levels was seen compared to the probiotic and control breads ( P > 0.05 ) . Trial registry code : http://www.i rct .ir I RCT 201311215623N13 BACKGROUND The short-chain fatty acids formed in the human colon by the bacterial fermentation of fiber may have an antiinflammatory effect , may reduce insulin production , and may improve lipid metabolism . We previously showed in hypercholesterolemic patients that supplementation with the probiotic bacteria Lactobacillus plantarum 299v significantly lowers concentrations of LDL cholesterol and fibrinogen . OBJECTIVE We determined the influence of a functional food product containing L. plantarum 299v on lipid profiles , inflammatory markers , and monocyte function in heavy smokers . DESIGN Thirty-six healthy volunteers ( 18 women and 18 men ) aged 35 - 45 y participated in a controlled , r and omized , double-blind trial . The experimental group drank 400 mL/d of a rose-hip drink containing L. plantarum 299v ( 5 x 10(7 ) colony-forming units/mL ) ; the control group consumed the same volume of product without bacteria . The experiment lasted 6 wk and entailed no changes in lifestyle . RESULTS Significant decreases in systolic blood pressure ( P < 0.000 ) , leptin ( P < 0.000 ) , and fibrinogen ( P < 0.001 ) were recorded in the experimental group . No such changes were observed in the control group . Decreases in F(2)-isoprostanes ( 37 % ) and interleukin 6 ( 42 % ) were also noted in the experimental group in comparison with baseline . Monocytes isolated from subjects treated with L. plantarum showed significantly reduced adhesion ( P < 0.001 ) to native and stimulated human umbilical vein endothelial cells . CONCLUSION L. plantarum administration leads to a reduction in cardiovascular disease risk factors and could be useful as a protective agent in the primary prevention of atherosclerosis in smokers According to animal studies , intake of probiotic bacteria may improve glucose homeostasis . We hypothesised that probiotic bacteria improve insulin sensitivity by attenuating systemic inflammation . Therefore , the effects of oral supplementation with the probiotic bacterium Lactobacillus acidophilus NCFM on insulin sensitivity and the inflammatory response were investigated in subjects with normal or impaired insulin sensitivity . In a double-blinded , r and omised fashion , forty-five males with type 2 diabetes , impaired or normal glucose tolerance were enrolled and allocated to a 4-week treatment course with either L. acidophilus NCFM or placebo . L. acidophilus was detected in stool sample s by denaturating gradient gel electrophoresis and real-time PCR . Separated by the 4-week intervention period , two hyperinsulinaemic-euglycaemic clamps were performed to estimate insulin sensitivity . Furthermore , the systemic inflammatory response was evaluated by subjecting the participants to Escherichia coli lipopolysaccharide injection ( 0·3 ng/kg ) before and after the treatment course . L. acidophilus NCFM was detected in 75 % of the faecal sample s after treatment with the probiotic bacterium . Insulin sensitivity was preserved among volunteers in the L. acidophilus NCFM group , whereas it decreased in the placebo group . Both baseline inflammatory markers and the systemic inflammatory response were , however , unaffected by the intervention . In conclusion , intake of L. acidophilus NCFM for 4 weeks preserved insulin sensitivity compared with placebo , but did not affect the systemic inflammatory response Background Lactobacillus gasseri BNR17 is a type of probiotic strain isolated from human breast milk . A study was reported regarding the fact that BNR17 was an inhibitor of obesity and diabetic activities in the human body through previous animal experiments . This study was furthered to investigate the effect of BNR17 , a probiotic strain isolated from human breast milk , on obese and overweight adults . Methods Sixty-two obese volunteers aged 19 to 60 with body mass index ≥ 23 kg/m2 and fasting blood sugar ≥ 100 mg/dL participated in a placebo controlled , r and omized , and double-blind trial . For 12 weeks , 57 participants were given either placebo or BNR17 and were tested by measuring body fat , body weight , various biochemical parameters , vital signs , and computed tomography at the start of the study and at weeks 4 , 8 , and 12 . The subjects assumed usual daily activities without having to make behavioral or dietary modifications during the course of the study . Results At the 12th week , a slight reduction in body weight was noted in the BNR17 group , but there were no significant weight changes between groups . Decrease of waist and hip circumferences in the BNR17 group was more pronounced than those in the placebo group . The two groups had no special or severe adverse reactions . Conclusion Despite there being no change in behavior or diet , administration of only the supplement of BNR17  reduced weight and waist and hip circumference . However , there were no significant differences between the two groups . These findings warrant a subsequent longer-term prospect i ve clinical investigation with a large population Background The consumption of foods containing probiotic and prebiotic ingredients is growing consistently every year , and in view of the limited number of studies investigating their effect in the elderly . Objective The objective of this study was to evaluate the effect of the consumption of a symbiotic shake containing Lactobacillus acidophilus , Bifidobacterium bifidum and fructooligosaccharides on glycemia and cholesterol levels in elderly people . Methods A r and omized , double-blind , placebo-controlled study was conducted on twenty volunteers ( ten for placebo group and ten for symbiotic group ) , aged 50 to 60 years . The criteria for inclusion in the study were : total cholesterol > 200 mg/dL ; triglycerides > 200 mg/dL and glycemia > 110 mg/dL. Over a total test period of 30 days , 10 individuals ( the symbiotic group ) consumed a daily dose of 200 mL of a symbiotic shake containing 108 UFC/mL Lactobacillus acidophilus , 108 UFC/mL Bifidobacterium bifidum and 2 g oligofructose , while 10 other volunteers ( the  placebo group ) drank daily the same amount of a shake that did not contain any symbiotic bacteria . Blood sample s were collected 15 days prior to the start of the experiment and at 10-day intervals after the beginning of the shake intake . The st and ard lipid profile ( total cholesterol , triglycerides and HDL cholesterol ) and glycemia , or blood sugar levels , were evaluated by an enzyme colorimetric assay . Results The results of the symbiotic group showed a non-significant reduction ( P > 0.05 ) in total cholesterol and triglycerides , a significant increase ( P < 0.05 ) in HDL cholesterol and a significant reduction ( P < 0.05 ) in fasting glycemia . No significant changes were observed in the placebo group . Conclusion The consumption of symbiotic shake result ed in a significant increase in HDL and a significant decrease of glycemia . Trial Registration Clinical Trials.gov : Abstract Throughout life , there is an aging of the immune system that causes impairment of its defense capability . Prevention or delay of this deterioration is considered crucial to maintain general health and increase longevity . We evaluated whether dietary supplementation with Lactobacillus delbrueckii subsp . bulgaricus 8481 could enhance the immune response in the elderly . This multi-center , double-blind , and placebo controlled study enrolled 61 elderly volunteers who were r and omly assigned to receive either placebo or probiotics .  Each capsule of probiotics contained at least 3 × 107 L. delbrueckii subsp . bulgaricus 8481 . Individuals in the study were administered three capsules per day for 6 months . Blood sample s were obtained at baseline ( time 0 ) , end of month 3 , and month 6 . We characterized cell sub population s , measured cytokines by flow cytometry , quantified T cell receptor excision circle ( TREC ) by real-time PCR ( RT-PCR ) , and determined human β-defensin-2 ( hBD-2 ) concentrations and human cytomegalovirus ( CMV ) titers by enzyme-linked immunosorbent assay ( ELISA ) . Elderly responded to the intake of probiotic with an increase in the percentage of NK cells , an improvement in the parameters defining the immune risk profile ( IRP ) , and an increase in the T cell subsets that are less differentiated . The probiotic group also showed decreased concentrations of the pro-inflammatory cytokine IL-8 but increased antimicrobial peptide hBD-2 . These effects disappeared within 6 months of stopping the probiotic intake . Immunomodulation induced by L. delbrueckii subsp . bulgaricus 8481 could favor the maintenance of an adequate immune response , mainly by slowing the aging of the T cell sub population s and increasing the number of immature T cells which are potential responders to new antigens To evaluate the effects of probiotic ( VSL#3 ) and
