Association of blood pressure and dietary intake of Sunomono, Japanese vinegared side dishes, in community-dwelling Japanese: A cross-sectional study.

Objective: Vinegar has been reported to have a hypotensive effect. We aimed to investigate the relationship between the consumption of vinegar-based side dishes and blood pressure. Research methods & procedures: This cross-sectional study included 746 individuals (257 men and 489 women) aged ≥40 years from Tarumizu, Kagoshima, Japan. Nutrient intake was estimated based on the brief-type self-administered diet history questionnaire. The intake frequency of vinegar-based side dishes (Sunomono and pickles) was determined using a self-administered diet history questionnaire. Participants who did not consume vinegar-based side dishes for a month were defined as having no Sunomono or pickle eating habit. Blood pressure was categorized into four groups according to the Japanese Society of Hypertension Guidelines for the Management of Hypertension. The association between the intake of vinegar-based side dishes and blood pressure categories was analyzed using ordinal logistic regression analysis adjusted for age, body mass index, smoking history, excessive alcohol intake, living situation, energy intake, protein intake, sodium intake, potassium intake, and seaweed intake. Results: Approximately 13.6% men and 6.1% women had no Sunomono eating habits. In men, eating Sunomono, but not pickles, was significantly related to blood pressure categories (estimate, -0.702; 95% CI, -1.122 to -0.310), whereas more frequent consumption of Sunomono did not show an improvement in the blood pressure category. The relationship between eating Sunomono and blood pressure categories was not recognized in women. Conclusion: This was the first study assessing the association between consumption of vinegar-based side dishes and blood pressure categories. We highlighted the effect of Sunomono consumption on blood pressure categories in men. Consumption of Sunomono may improve blood pressure in men.

Association of Protein and Magnesium Intake with Prevalence of Prefrailty and Frailty in Community-Dwelling Older Japanese Women.

We examined the association between nutrient intake and prefrailty. Data from 815 older people (63% women) who participated in a community-based health check survey (Tarumizu Study) were analyzed. Prefrailty were defined using five parameters (exhaustion, slowness, weakness, low physical activity, and weight loss). Participants with one or more components were considered to belong to the prefrailty group. Nutrition intake was estimated from a validated brief-type self-administered diet history questionnaire. Among the participants, 154 men (52%) and 278 women (54%) were found to be in a status of prefrailty. In men, there were no significant associations between nutrient intake and prefrailty. In women, carbohydrate intake was slightly higher in prefrailty group. Vitamins K, B1, B2, folic acid, pantothenic acid, phosphorus, potassium, calcium, magnesium, iron, zinc, and copper intake was significantly lower in the prefrailty group. Among the nutrients, magnesium was identified as a significant covariate of prefrailty using a stepwise regression method. In women adjusted ORs (95%CI, p value) for prefrailty in the first, second, third, and fourth quartiles of magnesium intake were 1.00 (reference), 0.52 (0.29-0.92, 0.024), 0.51 (0.28-0.95, 0.033), and 0.38 (0.19-0.74, 0.005), respectively, by multivariate logistic regression analysis (variates: age, body mass index, energy intake, supplement use, osteoporosis, magnesium, and protein intake). Protein intake did not related to prefrailty. Protein intake might be sufficient to prevent prefrailty in the present study. We propose magnesium to be an important micronutrient that prevents prefrailty in community-dwelling older Japanese women.

Progressive systemic sclerosis-polymyositis overlap syndrome with eosinophilic pleural effusion.

Pleural fluid rarely occurs in patients with progressive systemic sclerosis (PSS) or polymyositis (PM) with no lesions in the pulmonary area. Pleural fluids in patients with autoimmune diseases are mostly dominated by monocytes and lymphocytes but very rarely contain increased eosinophils. We report a 55-year-old male with PSS-PM overlap syndrome and eosinophilic pleural effusion. Air invasion into the pleural cavity and the antituberculous therapy could be ruled out as causes for the patient's eosinophilic pleural effusion, because the differential eosinophil count was already as high as 19% from the first thoracentesis before the start of antituberculous therapy. Infections and malignant tumor also were unlikely causes based upon the negative pleural fluid results and the negative pleural biopsy findings, except for nonspecific inflammation. After the administration of corticosteroid, the pleural effusion decreased promptly, with normalization of serum creatine phosphokinase and C-reactive protein concentrations.
