Fruit and Vegetable Consumption and the Risk of Bone Fracture: A Grading of Recommendations, Assessment, Development, and Evaluations (GRADE)-Assessed Systematic Review and Dose-Response Meta-Analysis.

Researchers have examined the link between consuming fruit and vegetables and the incidence of fractures for many years. Nevertheless, their findings have been unclear. Furthermore, the dose-dependent relationship has not been examined, and the level of certainty in the evidence was not evaluated. We carried out a dose-dependent meta-analysis examining the relation between fruit and vegetables intake and fracture incidence. PubMed, Web of Sciences, and Scopus were searched until April 2023 for cohort studies evaluating the relation between fruit and vegetables and fracture incidence. Summary relative risks (RRs) were computed from complied data by applying random effects analysis. To examine the level of evidence, we utilized the approach called the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE). Ten cohort studies comprising 511,716 individuals were entered. There was a nonsignificant relation between fruit and vegetables, as well as only fruit intake and any fracture risk. In contrast, high versus low analysis presented that vegetables consumption was linked to a 16% decrease in any type of fracture incidence (RR 0.84; 95% confidence interval [CI], 0.75 to 0.95; I 2 = 83.1%; n = 6). Also, per one serving/day (200 g/day) increments in vegetables consumption, there was a 14% decline in the fracture risk (RR 0.86; 95% CI, 0.77 to 0.97; I 2 = 84.7%; n = 5; GRADE = moderate). With moderate certainty, a greater consumption of only vegetables, but not total fruit and vegetables or only fruit, might reduce the risk of fracture. These associations were also evident in dose-response analysis. Large intervention trials are demanded to approve our findings. © 2023 The Authors.

The Possible Mediatory Role of Inflammatory Markers on the Association of Dietary Insulin Index and Insulin Load with Metabolic Syndrome in Women with Overweight and Obesity: A Cross-Sectional Study.

Background: Metabolic syndrome (MetS) is associated with increased inflammation. Diet plays an important role in the prevention and management of MetS, while some dietary factors can also increase or decrease markers of systemic inflammation. In this study, we aimed to determine the mediated association of inflammatory markers induced by dietary insulin index (DII) and dietary insulin load (DIL) with MetS and its components. Methods: This cross-sectional study was conducted with 219 women aged 18-28 years. Dietary intake was assessed by a 147-item food frequency questionnaire (FFQ). DII and DIL were calculated using the standard formula. The guidelines of the National Cholesterol Education Program's Adult Treatment Panel III were used to define MetS. Biochemical parameters and anthropometric and blood pressure measures were evaluated by standard protocols. Results: After the adjustment for potential confounders, a marginally significant association was found between DII and MetS (OR = 2.11; 95% CI = 0.93-4.82; P = 0.06). However, we did not find a significant association between DIL and MetS. Furthermore, DII was significantly associated with waist circumference (WC) (OR = 1.67; 95% CI = 1.09- 4.03; P = 0.03) and marginally associated with triglyceride (TG) (OR = 1.10; 95% CI = 0.92-2.33; P = 0.07) and systolic blood pressure/diastolic blood pressure (SBP/DBP) (OR = 1.84; 95% CI = 0.85-3.99; P = 0.07). Moreover, there was a significant association between DIL and SBP/DBP (OR = 1.74; 95% CI = 1.54-5.61; P = 0.04). Also, we found that MCP-1 may have a mediatory role in the association between DII and DIL with MetS and several components of MetS. Hs-CRP did not have mediatory role in the association between DII and MetS. However, hs-CRP had a mediatory role in several MetS components. Furthermore, hs-CRP may have a mediatory role in the association of DIL with MetS and with some of its components. Conclusions: A higher DII score may increase the odds of MetS and its components. DIL was not significantly associated with the odds of MetS, but the association of DIL and SBP/DBP was significant. MCP-1 may have a mediatory role in associations between DII and DIL with MetS. In addition, hs-CRP may have a mediatory role in the association between DIL and MetS.

Adjuvant pomegranate juice intake improves the inflammatory status of hospitalized COVID-19 patients: A randomized and placebo-controlled trial.

BACKGROUND: This study aimed to evaluate the effect of pomegranate juice intake on the inflammatory status and complete blood count in hospitalized Covid-19 patients. METHODS: This randomized, double-blinded placebo-controlled trial included 48 patients with two parallel arms. In addition to the standard care provided at the hospital, the patients consumed 500 mL of whole pomegranate juice (PJ) daily or a placebo for 14 days. Inflammatory markers (C-reactive protein (CRP), interleukin-6 (IL-6), erythrocyte sedimentation rate (ESR)) and complete blood count were determined at baseline and after the 14 days of intervention. RESULTS: At the end of the intervention, a significant decreased was observed in primary outcomes [mean difference (95 %CI)] including IL-6 [5.24(0.87-9.61)], CRP [23.19(11.93-34.44)] and ESR [10.52(1.54-19.50)] in the PJ group vs. before the intervention. In addition, significant changes were also observed in the some of the secondary outcomes, including neutrophils, lymphocytes, platelets, platelets-to-lymphocyte(PLR) and neutrophils-to-lymphocyte (NLR) ratios (p < 0.05) in the PJ group compared to before the intervention. At the end of the intervention period, the mean change of IL-6 [- 7.09(-12.21 to - 1.96)], white blood cells [- 3.09(- 6.14 to - 0.05)], neutrophils [- 9.12(-18.08 to -0.15)], lymphocyte [7.05(0.17-13.92)], platelets [- 94.54(- 139.33 to - 49.75)], PLR [- 15.99(- 29.31 to - 2.67)], blood oxygen saturation [1.75(0.13-3.37)] and MCV [0.31(- 0.25 to 0.88)] levels were significantly different between groups while no difference was observed between the two groups in other blood indices. CONCLUSION: Our results suggest that pomegranate juice intake might slightly improve the inflammatory status and CBC outcomes of COVID-19 patients and it may be beneficial.

MDR1 gene C3435T polymorphism in chronic hepatitis C patients.

BACKGROUND: MDR1 is a highly polymorphic gene that encodes P-glycoprotein (P-gp). This protein anchor to the cell membrane and transports toxins, xenobiotic, chemicals, and drugs from the intracellular to extracellular and thus protect cells. Polymorphism of the MDR1 gene seems to be effective in gene expression and response to treatment. Since one of the main mechanisms of drug resistance is the removal of the drug from the cell by ATP-dependent efflux proteins, thus MDR1, single nucleotide polymorphism (SNP) C3435T can be used as a predictor for treatment outcomes. METHODS: The peripheral blood-EDTA samples were collected from 71 patients with chronic hepatitis C. The total genomic DNA extraction was carried out. The PCR was performed for detection of the MDR1 gene in HCV patients and MDR1 gene polymorphism was genotyped by the PCR-RFLP method. RESULTS: Out of 71 patients 52 (73.3%) were male, 19 (26.7%) female with mean age-min-max; 41.17 ± 8.3-(26-59). The distribution of MDR1 genotype in 48(67.6%) responders were CC 13 (27%), CT 34 (71%) and TT 1(2%), while MDR1 genotypes in 8 (11.3%) non responders were CC 2(25%), CT 1(12.5%) TT 5(62.5%) and in 15(21.1%) recurrence were 5 (33%) CC, 6 (40%) CT and 4 (27%) TT genotype. The patients with heterozygous CT (C3435T) genotype 34/48(71%) were found better response than non-responders with TT 5/8(62.5%) genotype (p < 0.05). CONCLUSION: Our result reveals that 71% of the responders were CT genotypes (C3435T) and 62.5% of non-responders were TT genotype (T3435T). With aforementioned results, determination of different forms of SNPs in MDR1 gene should be considered as a predictor in the treatment of all chronic HCV patients. The homozygous TT genotype and high prevalence of T allele may be related to low antiviral response during combined therapy in treatment of chronic HCV patients.
