AI Article Synopsis
- Attention to purine intake is crucial for managing hyperuricemia, particularly in patients who are also obese and seek to lose weight through glucose restriction.
- A study compared the purine content and potential renal acid load (PRAL) of normal hospital diets, energy-control diets, and low-carbohydrate diets, finding that low-carb diets had significantly higher purine content.
- It is advised that dietitians prefer hospital diets over low-carb diets for patients with hyperuricemia due to lower purine intake and acid load in the former.
Article Abstract
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.

The main aim of this work was to study the chemical composition of eighteen ground coffees from different countries and continents with regard to the content of hazardous substances as radioactive elements (K, Ra, Ra, U, U and Cs), metals, including heavy metals, aluminum and some microelements (V, Cr, Mn, Fe, Co, Ni, Cu, Zn) as well as substances that have a positive effect on human health and well-being (polyphenols, proteins, fats and caffeine). The tests were carried out before and after the brewing process using the following techniques: gamma and beta spectrometry, a microwave-induced plasma optical emission spectrometer (MIP-OES), gravimetric method, UV-Vis spectrophotometry as well as thin-layer chromatography. The leaching percentage of certain elements/compounds in coffee infusions was also measured.

Intracerebral hemorrhage (ICH) is a devastating form of stroke with a lack of effective treatments. Following disease onset, ICH activates microglia and recruits peripheral leukocytes into the perihematomal region to amplify neural injury.

Lung cancer is one of the most harmful cancers in the world, endangering the lives and health of many people. Although there are various methods to treat lung cancer at present, but lung cancer is asymptomatic in the early stages and has a high recurrence rate after late treatment which make it difficult to cure with conventional treatments. Drug combinations for the treatment of lung cancer have been used in many clinical studies.
