RESUMO

BACKGROUND: The use of plants for therapeutic purposes has been supported by growing scientific evidence. METHODS: This work consisted of (i) characterizing the phenolic compounds present in both aqueous and hydroethanol (1:1, v/v) extracts of camel grass, by hyphenated liquid chromatographic techniques, (ii) evaluating their anti-inflammatory, antioxidant, and neuromodulation potential, through in vitro cell and cell-free models, and (iii) establishing a relationship between the chemical profiles of the extracts and their biological activities. RESULTS: Several caffeic acid and flavonoid derivatives were determined in both extracts. The extracts displayed scavenging capacity against the physiologically relevant nitric oxide (•NO) and superoxide anion (O2•-) radicals, significantly reduced NO production in lipopolysaccharide (LPS)-stimulated macrophages (RAW 264.7), and inhibited the activity of hyaluronidase (HAase), acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). Some of these bioactivities were found to be related with the chemical profile of the extracts, namely with 3-caffeoylquinic, 4-caffeoylquinic, chlorogenic, and p-coumaric acids, as well as with luteolin and apigenin derivatives. CONCLUSIONS: This study reports, for the first time, the potential medicinal properties of aqueous and hydroethanol extracts of camel grass in the RAW 264.7 cell model of inflammation, and in neurologically related conditions.

RESUMO

AIM OF THE STUDY: To identify the 10 drugs most frequently administered to children in liquid dosage forms which are eligible for replacement with suitable authorized solid dosage forms and to assess the expected economic impact of this substitution. METHODS: The health record data from 312,152 oral drug administrations were analyzed. Ten drugs were selected according to their frequency of administration in liquid dosage forms, the availability of solid form alternatives, and the suitability of these alternatives for the children receiving the corresponding liquid forms. Potential hospital cost savings of the suggested substitutions were calculated. RESULTS: The 10 drugs identified as most frequently administered and for which suitable solid forms were available were: paracetamol, cyamemazine, valproic acid, clonazepam, furosemide, prazepam, hydroxyzine, alfacalcidol, amitriptyline, and levetiracetam. Thirty-four point six of the administrations of these drugs in liquid dosage forms could be delivered using suitable solid dosage forms without additional cost. CONCLUSION: Opportunities exist for substituting liquid dosage forms with market-available solid dosage forms suitable in size and dosage for the pediatric population.

RESUMO

The present study on long-term outcome of presymptomatic testing for Machado-Joseph disease (MJD) aimed to evaluate the psychological well-being and the familial satisfaction of subjects that 5 years prior received an unfavorable result in the predictive testing (PT). The study included 47 testees of Azorean origin (23 from the island of Flores and 24 from S. Miguel) that completed the fourth evaluation session of the MJD protocol, and undertook a neurological examination at the moment of participation in the study. Nearly 50% of testees were symptomatic at the time of the study. Psychological well-being of the 47 participants was evaluated using the Psychological General Well-Being Index (PGWB). The family satisfaction scale by adjectives was applied to obtain information on family dynamics. The average PGWB score of the total participants was of 73.3, a value indicative of psychological well-being. Nearly half of the testees presented scores indicating psychological well-being, whereas scores indicating moderate (28.9%) or severe (23.7%) stress were found in the remaining. The average score in the PGWB scale was lower in symptomatic than in asymptomatic subjects; moreover, the distinct distribution of the well-being categories seen in the two groups shows an impact of the appearance of first symptoms on the psychological state. Motives for undertaking the test, provided 5 years prior, failed to show an impact in well-being. The average score for familial satisfaction was of 134, a value compatible with high familial satisfaction, which represented the most frequent category (59.6%). Results demonstrate that well-being and family satisfaction need to be monitored in confirmed carriers of the MJD mutation. The inclusion of acceptance studies, after PT, as well as the development of acceptance training actions, should be of major importance to anticipate the possibility of psychological damage.
