Background: Cystic fibrosis is a progressive, fatal disease affecting the quality of life. The cystic fibrosis questionnaire-revised (CFQ-R) is an efficient tool to monitor health-related quality of life in patients. The aim of this study was to explore the psychometric properties of the child and parent versions of the Persian version of the CFQ-R in the Iranian population.

Methods: Fifty children with cystic fibrosis (6-11 years) and their parents were allocated in this methodological study to examine convergent validity, discriminant validity, test-retest reliability (n = 30), internal consistency, ceiling and floor effects, and agreement between two versions of the CFQ-R.

Results: Convergent validity was confirmed for parent proxy (P < 0.05). CFQ-R discriminated patients among stages of disease severity based on lung function, age, and BMI (P < 0.05). Test-retest analysis revealed good to excellent reliability (inter-class correlation coefficient (ICC) = 0.78-0.97). In most domains, lower quality of life scores was obtained in the parent proxy compared to the child version (P < 0.05). Domain-specific correlations were found between the child version and parent proxy (P < 0.05). Internal consistency was generally confirmed (α = 0.13-0.83 in child version and α = 0.25-0.87 in parent proxy). There were no floor effects. Ceiling effects were mostly seen for physical, digestion, and body image domains in the child version and for eating, weight, and school domains in the parent proxy.

Conclusions: The child version and parent proxy of the Persian CFQ-R are valid and reliable measures and can be applied in clinical trials to monitor the quality of life in children with cystic fibrosis. It is recommended to use both versions in conjunction to better interpret the quality of life aspects of children with cystic fibrosis.

Background: This systematic review and meta-analysis aim to update the pooled prevalence of Inflammatory bowel disease (IBD) in patients with multiple sclerosis (MS).

Methods: Two researchers independently and systematically searched PubMed, Scopus, EMBASE, Web of Science, and google scholar. They also searched for references of the included studies, and conference abstracts that were published up to September 2021.

Results: The literature search revealed 5719 articles, after deleting duplicates 3616 remained. Finally, 17 studies were included. The pooled prevalence of IBD in MS was 1% (I² = 96.3%, P < 0.001). The pooled odds ratio of developing IBD in MS cases was 1.36 (95% CI: 1.1-1.6) (I² = 58.3, P = 0.01).

Conclusions: The results of this systematic review and meta-analysis show that the pooled prevalence of IBD in MS patients was 1% and the pooled odds ratio of developing IBD in MS cases was 1.36.

Background: Both aging and diabetes are two well-established risk factors related to type 3 diabetes and memory deficits. Accordingly, diabetes multiplies the effects of aging on cognition impairments once these conditions occur simultaneously.

Methods: In this present experimental study, 56 male Wistar rats with HFD/STZ-induced T2D were randomized into seven groups (n = eight animals per group): (1) sedentary old non-diabetic (C); (2) sedentary HFD/STZ-induced T2D (D); (3) sedentary HFD/STZ-induced T2D plus UA (UA) (DU); (4) endurance-trained HFD/STZ-induced T2D (DE); (5) resistance-trained HFD/STZ-induced T2D (DR); (6) endurance-trained HFD/STZ-induced T2D plus UA (DEU); and (7) resistance-trained STZ-diabetic plus UA (DRU) rats. Two-way ANOVA was applied to measure the training, supplementation, and interaction effect on serum and gene expression outcomes.

Result: The study results established no significant interaction effect between the UA supplementation and the resistance/endurance training with regard to the levels of glucose (P = 0.534), insulin (P = 0.327), brain-derived neurotrophic factor (P = 0.191), and insulin-like growth factor-1 (P = 0.448).

Conclusions: To develop novel practical nutritional strategies involving UA intake, further studies are thus needed to clarify how chronic consumption of UA with/without resistance/endurance training reverses cognition disorder process in old male Wistar rats with HFD/STZ-induced T2D.
