Purine Content and Renal Acid Load Evaluation in Healthy Japanese Diets.

During the treatment of hyperuricemia, attention should be paid to purine intake as part of the diet. Additionally, many patients with obese hyperuricemic expect early weight loss through glucose restriction. However, the amounts of purine in the diet are unknown. This study aimed to compare the purine content and potential renal acid load (PRAL) of a hospital diet and a low carbohydrate (LC). We calculated the nutritional values in the menus of the normal hospital (NH), energy-control (EC) diets served at several Shizuoka general hospitals, and the menus of LC diets. The amount of purine and PRAL was determined based on the nutritional values. The average daily purine content and energy were NH 349.0 mg, 1,808 kcal, EC 340.4 mg, 1,681 kcal, and LC 697.6 mg, 1,454 kcal, respectively. LC consumed more purine than the recommended daily intake of 400 mg. The PRAL score for NH was 4.5 mEq/d, EC 3.8 mEq/d, and LC 19.0 mEq/d, with LC representing diets with a higher acid load. In terms of both purine intake and uric acid excretion, the hospital diet is preferred over the low-carbohydrate diet for patients. Dietitians should exercise caution when recommending a low-carbohydrate diet for patients with hyperuricemia.

Relationship between parental autistic traits and parenting difficulties in a Japanese community sample.

BACKGROUND: Previous studies have suggested an association between higher levels of parental autistic traits and negative aspects of parenting; however, the domain of autistic traits specifically associated with parenting difficulties has not been investigated yet. Moreover, it remains to be determined whether this association exists even after controlling for children's characteristics. AIMS: This study examined the relationship between each domain of parental autistic traits and parenting difficulties after controlling for children's characteristics in a Japanese community sample. METHODS AND PROCEDURES: Surveys were administered to 1373 Japanese adults who were parents to children in kindergartens, nursery schools, and elementary schools. OUTCOMES AND RESULTS: The results showed that parents with higher levels of autistic traits had more parenting difficulties. Even after controlling for children's sex, age, and emotional/behavioral problems, paternal impaired communication and maternal poor attention switching, impaired communication, and lack of imagination were related to higher parenting difficulties, while a higher maternal level of attention to detail was associated with lower difficulties in parenting. CONCLUSIONS AND IMPLICATIONS: The findings of this study highlight the importance of focusing on parental autistic traits and providing appropriate parenting support considering these traits.
