Probiotics affect biomarkers indicative of bone formation, such as alkaline phosphatase (ALP), calcium status, bone mineralization, bone turnover markers and metabolism. This study aims to investigate the effects of synbiotic on gastrointestinal (GI) disorder, bone complications and anemia in hemodialysis (HD) patients. In this randomized, double-blind, placebo-controlled clinical trial study, HD patients received 2 symbiotic (n = 19) or placebo (n = 17) capsules daily for 12 weeks. GI function, serum levels of bone-specific biomarkers, and serum levels of anemia-specific biomarkers were assessed at the beginning and the end of study. GI function was assessed with gastrointestinal symptom rating scale questionnaire. The data were analyzed using SPSS. At the end of this study, parathyroid hormone levels decreased significantly in the synbiotic group (p = 0.039); however, in comparison to placebo group, the difference was not significant. Decrease of ALP levels in the synbiotic group were not statistically significant. However, a significant difference was seen between the 2 groups at the end of intervention (p = 0.037). Improvement in GI symptoms was observed in both groups, but the reduction rate was higher in the synbiotic group. Additionally, at the end of the study, a significant difference between the 2 groups was observed (p < 0.05). No statistically significant difference was observed in the levels of other factors within each group and between the 2 groups (p > 0.05). Symbiotic supplements after 12 weeks led to an improvement in GI function and ALP levels in HD patients. Further investigation into bone-mineral disorders in HD patients is necessary.

Pickle is consumed in high amount among Iranians. Pickle consumption may be related to body mass index (BMI) and blood pressure (BP) but limited evidence exist in this regard. The aim of current study was to determine the association between pickle consumption and risk of overweight, central obesity and BP among Isfahanian female youths. A cross-sectional study was conducted on 289 female students aged 18–27 years randomly selected from students of Isfahan University of Medical Sciences, Isfahan, Iran. Diet was assessed by a validated and reliable food-frequency questionnaire. Mean pickle consumption was 15.1 ± 2.2 g/day. Individuals in the highest tertile of pickle consumption had a significantly higher BMI, systolic and diastolic BP (p = 0.001, 0.03, and 0.03, respectively), whereas we did not observe significant association for waist circumference (p = 0.21). Total energy intake (p = 0.02) and consumption of carbohydrate (p = 0.01), protein (p = 0.03), and fat (p = 0.05) in the upper tertile was higher than lower tertiles. There was a significant association between pickle consumption and obesity and BP among Iranian female youths. Further prospective studies are needed to confirm this association.

Pycnogenol is a standardized extract from the bark of the French maritime pine. The aim of the present systematic review and meta-analysis was to clarify the effect of Pycnogenol supplementation on C-reactive protein (CRP) concentration. To identify eligible studies in order to find clinical trials which examined the effect of Pycnogenol supplementation on the level of CRP in adult participants, PubMed, Scopus, and Google Scholar were systematically searched until December 2017. Mean of CRP was collected to estimate the effect size of the supplementation. Potential sources of heterogeneity were explored by subgroup analysis. Five trials including 324 participants were included in this meta-analysis. Pooled effect size showed significant effect of Pycnogenol supplementation on CRP (−1.22 mg/dL, 95% confidence interval, −2.43, −0.003; I2 = 99%, pheterogeneity < 0.001). When the meta-analysis was subgrouped by dose of Pycnogenol, heterogeneity was attenuated in > 150 mg/d category (I2 = 0.0%, p = 0.42). There was significant difference between-subgroup heterogeneity (p < 0.001). Furthermore, no evidence of publication bias for CRP (p = 0.27, Begg's test and p = 0.62, Egger's test) was seen. Present systematic review and meta-analysis suggested Pycnogenol consumption can decrease the level of CRP and have anti-inflammatory effect. So, Pycnogenol as an anti-inflammatory agent might be a priority in interventions. Further studies with large-scale and better design are needed to confirm this result.
