Interventions to Reduce Problems Related to the Readability and Comprehensibility of Drug Packages and Labels: A Systematic Review.

Objective: The aim of the study was to evaluate the effectiveness of interventions designed to reduce problems with readability and comprehensibility in drug labels.

Methods: A systematic review of observational and experimental studies was conducted using MEDLINE (via PubMed), Embase, and Scopus databases. Two independent reviewers selected articles and collected data about study design, interventions, and outcomes.

Users' preferences and perceptions of the comprehensibility and readability of medication labels.

Objective: To evaluate the labeling preferences of medication users and characterize their perceptions of the comprehensibility and readability of medication labels.

Methods: We conducted a population-based cross-sectional study of medication users aged 18 years or older in 10 Brazilian capital cities. Perceptions of the comprehensibility and readability of medication labels in relation to sociodemographic characteristics were evaluated by Poisson regression models with robust variance.

Mode of action of antimicrobial peptide P45 on Listeria monocytogenes.

The mode of action of an antimicrobial peptide produced by Bacillus sp. P45 isolated from the intestine of the Amazonian basin fish Piaractus mesopotamicus was investigated. The antimicrobial peptide was purified from culture supernatants by precipitation with ammonium sulfate and gel filtration chromatography.

The effect of Lorenzo's oil on oxidative stress in X-linked adrenoleukodystrophy.

X-linked adrenoleukodystrophy (X-ALD) is a peroxisomal disorder biochemically characterized by the accumulation of very long chain fatty acids (VLCFA), particularly hexacosanoic acid (C(26:0)) and tetracosanoic acid (C(24:0)), in tissues and biological fluids. Although patients affected by this disorder predominantly present central and peripheral demyelination as well as adrenal insufficiency, the mechanisms underlying the brain damage in X-ALD are poorly known. The current treatment of X-ALD with glyceroltrioleate (C(18:1))/glyceroltrierucate (C(22:1)) (Lorenzo's oil, LO) combined with a VLCFA-poor diet normalizes VLCFA concentrations, but the neurological symptoms persist or even progress in symptomatic patients.
