Production of tomato powder from tomato puree with foam-mat drying using green pea aquafaba: drying parameters and bioaccessibility of bioactive compounds.

BACKGROUND: The purpose of this study was to valorize green pea cooking water (aquafaba) as a foaming agent in foam-mat drying of tomato. For this aim, density of foam-mats (green pea aquafaba+tomato puree) changed between 1.06 and 0.45 g/mL depending on the aquafaba concentration. Foam-mats with 5 mm thickness were dried at 50, 60 and 70°C at 1.3 m/s air velocity. RESULTS: The results showed that the porous structure of foams with lower densities resulted in higher drying rates and moisture diffusivities. Redness (a* ) value decreased with increasing aquafaba content (p < 0.05). Total phenolic content (TPC) and antioxidant activity (CUPRAC, DPPH and FRAP) of the resulting tomato powders were also determined. Moreover, bioaccessibility of phenolics and antioxidant activities were also determined using in vitro digestion. CONCLUSIONS: All of the bioactive parameters are positively affected by foam-mat drying process. Using aquafaba as a foaming agent accelerated the drying period and improved bioactive characteristics of the powders. © 2022 Society of Chemical Industry.

Systemic Sclerosis Quality of Life Questionnaire (SScQoL): translation into Turkish and assessing its psychometric properties.

BACKGROUND: Systemic sclerosis (SSc) is a chronic autoimmune disease that affects the connective tissues and leads to physical, emotional, and social challenges for patients. Evaluating health-related quality of life (HRQoL) with a disease-specific tool may be preferable for improving patient care and treatment outcomes. The aim of this study was to translate the Systemic Sclerosis Quality of Life Questionnaire (SScQoL) into Turkish and to investigate its psychometric properties. METHODS: Eighty-six patients with SSc (mean age 51.8 ± 11.7 years, 80 females) participated in the study. Convergent validity was explored by correlation analyses between Turkish SScQoL and Short-Form 36 (SF-36), European Quality of Life Survey-5 Dimensions (EQ-5D), EQ-5D Visual Analog Scale (EQ-VAS), and Scleroderma Health Assessment Questionnaire (SHAQ). Cronbach's alpha was calculated to test internal consistency. Turkish SScQoL was readministered after 7-14 days to fifty-eight patients for determining test re-test reliability. Intraclass correlation coefficients in 95% confidence interval (ICCs [95%CI]) were calculated to examine the agreement between two assessments. Values greater than 15% and an absolute skewness value < 1 were recognized as the presence of a floor or ceiling effect. RESULTS: SScQoL correlated significantly with SF-36 subdomains (r = -0.347 to -0.618, p < 0.01), EQ-5D (r = -0.535, p < 0.01), EQ-VAS (r = -0.636, p < 0.01), and SHAQ global score (r = 0.521, p < 0.01). SScQoL demonstrated excellent internal consistency (Cronbach's alpha = 0.917), and good to excellent test-retest reliability (ICC [95%CI] = 0.85 [0.76-0.91]). No floor/ceiling effects were observed. CONCLUSION: The Turkish version of SScQoL seems to have adequate psychometric properties and can be used to evaluate HRQoL in clinical and research settings. Key points • Turkish version of SScQoL is a valid and reliable tool for measuring health-related quality of life of patients with systemic sclerosis. • SScQoL is the only diseases-specific quality of life measurement for systemic sclerosis available in Turkish. • Patients with limited and diffuse SSc seem to be similar in terms of self-reported health-related quality of life.

Relationship between Helicobacter pylori Infections in Diabetic Patients and Inflammations, Metabolic Syndrome, and Complications.

Helicobacter pylori infection and diabetes mellitus are two independent common diseases. It is showed that the worsening glycemic and metabolic control increases the rates of Helicobacter pylori infections and Helicobacter pylori is shown as one of the common problems in diabetic patients with complaints of gastrointestinal diseases. In this study, we aimed to investigate the prevalence and eradication rates of Helicobacter pylori in diabetic patients and the relationship of Helicobacter pylori with the risk factors and diabetic complications. In our study, in which we have included 133 patients, we have shown a significant relationship between Helicobacter pylori infections and metabolic syndrome, insulin resistance, inflammations, and diabetic complications.
