Cardiovascular disease (CVD) is the leading cause of death in the US and worldwide. By 2030 it is anticipated that CVD will claim the lives of more than 24 million people. Throughout the last decade, researchers have investigated the role of the gut microbiota in the development of CVD. Evidence exists for a positive correlation between Bifidobacterium and vascular function, glucose tolerance, and reduced systemic inflammation. Another probiotic species, Bacillus subtilis, has also been found to reduce cholesterol levels in human and animal models. In light of these data, we examined various measures of cardiovascular health after consumption of Bifidobacterium animalis subsp. lactis strain BL04, with and without a cocktail of Escherichia coli-targeting bacteriophages (marketed as PreforPro), Bacillus subtilis strain DE111 or a maltodextrin-based placebo in a healthy human population. In a randomised, double-blind, placebo-controlled 4-week intervention conducted in individuals 18 to 65 years of age with a body mass index of 20 to 34.9, we saw no significant changes in measured CVD parameters among individuals consuming B. lactis with or without bacteriophages. However, B. subtilis supplementation resulted in a significant reduction in total cholesterol relative to baseline measures (-8 mg/dl; P=0.04, confidence interval (CI) -13.40, -0.19), as well as non-high-density lipoprotein-cholesterol (-11 mg/dl; P=0.01, CI -12.43, -2.07). In addition we observed trending improvements in endothelial function (P=0.05, CI -0.003, 0.370) and in low-density lipoprotein-cholesterol (P=0.06, CI-12.29, 0.2864). Strikingly, these effects were seen in a largely healthy population. These data suggest that B. https://www.selleckchem.com/products/canagliflozin.html subtilis supplementation may be beneficial for improving risk factors associated with CVD. Further studies in populations of older adults or those with dyslipidaemia and endothelial dysfunction is warranted.There is ample evidence suggesting that modulations in gut microbiota play an important role in inflammation and immunity. In particular, the microbiota of children is highly susceptible to environment influences, such as infections. Consequently, probiotics and their ability to promote and support a healthy microbiome have been increasingly studied. This study aimed at investigating the effects of a probiotic supplement (Bacillus subtilis DE111) on the microbiome composition of preschool aged children attending day care. Healthy children aged 2-6 years old were randomised to receive either probiotic or placebo once a day for 8 weeks. No significant changes of the overall microbiome equilibrium were seen in between the two groups or from baseline to week 8. However, alpha diversity was increased in the probiotic group from baseline to week 8 (P less then 0.05), with no change in the placebo group. A decrease in the Firmicutes/Bacteroidetes ratio following probiotic supplementation (P less then 0.05) was also observed. Differential abundance analysis revealed an increase in Alistepes (P less then 0.01), Bacteroides (P less then 0.05), Parabacteroides (P less then 0.01), Odoribacter (P less then 0.001) and Rikenellaceae (P less then 0.001) in the probiotic group, most of which are involved in inflammation reduction. In addition, a decrease in Eisenbergiella (P less then 0.001), Lactobacillales (P less then 0.01) and Streptococcaceae (P less then 0.01), which is considered pro-inflammatory, were also observed in the probiotic group. Together with a reduction of the F/B ratio observed in the probiotic group, these results suggest probiotic supplementation with Bacillus subtilis DE111 introduce subtle but positive changes in the microbiome of children aged 2-6 years old.Breast milk can be a source of potential probiotic bacteria, but the technological capacity of isolates obtained from this source is not always guaranteed. We aimed at isolating lactobacilli from breast milk samples collected in Argentina, focusing on isolates with functional and technological potential as probiotics. Fourteen Lactobacillus and one Bifidobacterium isolates were obtained from 164 samples donated by 104 mothers. The isolates preliminarily identified by MALDI-TOF, and then the identity was confirmed by partial 16S rRNA gene sequencing. Hydrophobicity was determined (hexadecane and xylene partition). The strains were also co-cultured with murine RAW 264.7 macrophages for screening the capacity to induce the anti-inflammatory cytokine interleukin (IL)-10. Hydrophobicity ranged from 7.4 and 95.9%. The strains Lactobacillus gasseri (70a and 70c) and Lactobacillus plantarum (73a and 73b) were the strains with a higher capacity to induce IL-10 production by macrophages. The technological application was evaluated by freezing dried in 10% lactose or 10% polydextrose. The survival was assessed after accelerated (37 °C, 4 weeks) or long-term (5 and 25 °C, 12 months) storage. Except for Lactobacillus gallinarum 94d, strains lost less than 1 Log10 order cfu/g after long-term (12 months) storage at 5 °C in lactose and polydextrose as protectants. A low correlation between survival to accelerated and long-term storage tests was observed. L. gasseri (70a and 70c) and L. plantarum (73a and 73b) deserve further studies as potential probiotics due to their capacity to induce IL-10 from murine macrophages and their hydrophobicity. In special, L. plantarum 73a was able to confer enhanced protection against Salmonella infection by promoting the immunity of the small intestine. Longstanding racial disparities in heart failure (HF) outcomes exist in the United States, in part, due to social determinants of health. We examined whether neighborhood environment modifies the disparity in 30-day HF readmissions and mortality between Black and White patients in the Southeastern United States. We created a geocoded retrospective cohort of patients hospitalized for acute HF within Emory Healthcare from 2010 to 2018. Quartiles of the Social Deprivation Index characterized neighborhood deprivation at the census tract level. We estimated the relative risk of 30-day readmission and 30-day mortality following an index hospitalization for acute HF. Excess readmissions and mortality were estimated as the absolute risk difference between Black and White patients within each Social Deprivation Index quartile, adjusted for geographic clustering, demographic, clinical, and hospital characteristics. The cohort included 30 630 patients, mean age 66 years, 48% female, 53% Black. Compared with White patients, Black patients were more likely to reside in deprived census tracts and have higher comorbidity scores.
