The effect of age on 12 chemical element contents in intact prostate of 64 apparently healthy, 13-60-year-old men (mean age 36.5 years) was investigated by inductively coupled plasma atomic emission spectrometry. Mean values (M ± SΕΜ) for mass fraction (milligrams/kilogram, on dry weight basis) of Ba, Ca, Cu, Fe, K, Mg, Na, P, S, Sr, and Zn were: Ba 1.18 ± 0.12, Ca 2,178 ± 160, Cu 10.7 ± 0.9, Fe 122 ± 5, K 12,530 ± 360, Mg 1,100 ± 70, Na 10,470 ± 320, P 7,580 ± 300, S 8,720 ± 180, Sr 1.85 ± 0.28, and Zn 782 ± 97, respectively. The upper limit of mean content of V was ≤0.22 mg/kg. A tendency of age-related increase in Ca, Fe, Na, and Zn mass fraction as well an increase in Zn/Ba, Zn/Ca, Zn/Cu, Zn/Fe, Zn/K, Zn/Mg, Zn/Na, Zn/P, Zn/S, and Zn/Sr ratios in prostate was observed. A significant positive correlation was seen between the prostatic zinc and Ca, Cu, Fe, Mg, Na, and P contents.

The combination of isoniazid (INH) and rifampicin (RIF) is indicated for the treatment maintenance phase of tuberculosis (TB) in adults and children. In Brazil, there is no current reference listed drug for this indication in children. Farmanguinhos has undertaken the development of an age-appropriate dispersible tablet to be taken with water for all age groups from birth to adolescence.

In recent years, the consumption of energy drinks (EDs) by adolescents and young adults has increased significantly, so concerns have been raised about the potential health risks associated with excessive ED consumption. Most analyses on EDs focus on the caffeine content. Research on the content of minerals (essential and toxic) in energy drinks can be considered scarce.

Given the current global circumstances, marked by severe environmental pollution-including the contamination of food-along with daily stress and a sedentary lifestyle, many consumers choose to improve their quality of life by using, among others, minimally processed food, food supplements, and gemmo-derivatives. Recent lab and clinical studies have shown the positive impact of specific nutrients with antioxidant capacities in the treatment of several conditions generated by oxidative stress. This paper reviews antioxidant plant extracts utilized as components in various dietary supplements and gemmoderivatives, highlighting their chemical composition and biological properties in preventing diseases caused by oxidative stress.

A double-blind, randomized, and controlled clinical trial with therapeutic intervention was performed at a university hospital in Rio de Janeiro to evaluate whether the addition of Hayne oleoresin to a carboxypolymethylene hydrogel is more effective in skin tear healing than standard treatment. The sample consisted of 84 patients, predominantly men, with a mean age of 67.37 years.
