Purpose: The purpose of this research was to test the validity and reliability of the Indonesian version of the Dietary Sodium Restriction Questionnaire (DSRQ-I) among patients with hypertension. Methods: The cross-sectional study enrolled hypertensive patients from a cardiac outpatient department in Indonesia using convenience sampling. Eligible patients received a demographic questionnaire and DSRQ-I during a one-month period of data collection. Content and construct analysis examined the validity, whereas internal consistency assessment checked reliability. Participation required 10-15 minutes on average. Results: One hundred thirty-five patients participated: mostly females (54.1%) and married (82.9%) with mean age of 58.18 ± 10.44 years. The item of content validity index was .97, and subscale content validity index was .81 for DSRQ-I. The KaisereMeyereOlkin test gave a value of .83, indicating adequate sampling, and the Bartlett's test of sphericity reached significant result (p < .001). The principal component analysis indicated three components, with 64.2% explaining variance, including perceived behavioral control (35.5%), attitude (19.3%), and subjective norm (9.4%). Confirmatory factor analysis produced a parsimonious model on the three-factor outcome by removing a single item. The indices of good fit model was achieved at x2/df = 2.17, goodness fit index = .85, root mean square error of approximation = .09, standardized root mean square means = .07, and Bentler comparative fit index = .90 (p < .001). Cronbach's alpha coefficients for attitude, subjective norm, and perceived behavioral control were .85, .87, and .85, respectively. All interitem and item-total correlations indicated adequate outcome and acceptable result. Consequently, 15 items were determined reliable measurement and included in the final version of DSRQ-I. Conclusion: The DSRQ-I is a valid and reliable instrument to measure facilitators and barrier of sodium restriction among hypertensive patients in Indonesia.

This study evaluated the effects of milk fermented with Pediococcus acidilactici strain BE and Pediococcus pentosaceus strain M103 on diabetes in rats (Rattus norvegicus). The bacteria were separately used as starter cultures for milk fermentation, and the products were then fed to diabetic rats for 15 days. Blood glucose levels, immunohistochemical and histological indicators, lipid profiles, and total lactic acid bacterium counts were evaluated before and after treatment. The administration of milk fermented with P. acidilactici strain BE reduced blood glucose levels from 410.27±51.60 to 304.07±9.88 mg/dL (p<0.05), similar to the effects of metformin (from 382.30±13.39 mg/dL to 253.33±40.66 mg/dL, p<0.05). Increased insulin production was observed in diabetic rats fed milk fermented with P. acidilactici strain BE concomitant with an increased number and percentage area of immunoreactive beta-cells. The structure of insulin-producing beta-cells was improved in diabetic rats fed milk fermented with P. acidilactici strain BE or metformin (insulin receptor substrate scores of 5.33±0.94 and 3.5±0.5, respectively). This suggests that the administration of milk fermented with P. acidilactici BE potentially reduces blood glucose levels and improves pancreatic betacell function in diabetic rats.
