In vitro anti-Candida activity of Glycyrrhiza glabra L.

The severity and frequency of opportunistic fungal infections still growing, concomitantly to the increasing rates of antimicrobial drug’s resistance. Natural matrices have been used over years due to its multitude of health benefits, including antifungal potential. Thus, the present work aims to evaluate the anti-Candida potential of the phenolic extract and individual phenolic compounds of Glycyrrhiza glabra L. (licorice), by disc diffusion assay, followed by determination of the minimal inhibitory concentration (MIC) and minimal fungicidal concentration (MFC) for both planktonic cells and biofilms. Licorice extract evidenced inhibitory potential against the nineteen tested Candida strains, but no pronounced effect was observed by testing the most abundant individual phenolic compounds. Candida tropicalis strains were the most sensible, followed by Candida glabrata, Candida parapsilosis and, then, Candida albicans. Lower MIC and MFC values were achieved to C. glabrata and C. tropicalis, which confirms its susceptibility to licorice extract; however, for C. tropicalis strains a higher variability was observed. Anti-biofilm potential was also achieved, being most evident in some C. glabrata and C. tropicalis strains. In general, a twice concentration of the MIC was necessary for planktonic cells to obtain a similar potential to that one observed for biofilms. Thus, an upcoming approach for new antifungal agents, more effective and safer than the current ones, is stablished; notwithstanding, further studies are necessary in order to understand its mechanism of action, as also to assess kinetic parameters.

Quality of life in institutionalized elderly undergoing an active aging program

Living with quality is a growing concern of the old population. There is an increasing institutionalization of the elderly, and it is in this context that active aging programs assume relevance, allowing the elderly the contact with experiences that allow them to age with quality of life, by maintaining their autonomy and promoting their physical, mental and emotional well-being. This study aims to assess the quality of life of institutionalized elderly undergoing to an active aging program. Methods: We have developed a semi-experimental study that considers the quantitative methodology in which the following instruments were used to measure the quality of life: Eurohis-Qol-8 (Pereira, Melo, Gameiro, & Canavarro, 2011) and Whoqol-Old (Vilar et al., 2010), to which sociodemographic and clinical questions were added. Assessments were made in two different moments, before and after the intervention program, in a sample of 37 institutionalized elderly. Results: Concerning the assessment of quality of life related to health (Eurohis-Qol-8), significant higher scores were obtained in the second moment (p = 0.004). Regarding the quality of life related to the elderly significant better scores were also obtained in the second assessment (p = 0.001). Conclusions: The results obtained allow us to conclude that using either of the measuring scales of Eurohis-Qol-8 or Whoqol-old, there is a perceived improvement in quality of life in those using the active aging program. Thus, institutionalized elderly must be the main target in the design and implementation of active aging programs.
