Abstract

Book Review: In the second edition of Tarot and Other Meditation Decks: History Theory, Aesthetics, Typology author Emily E. Auger examines Tarot's relationship to art movements, literature, and film. This expansion on the first edition adds a more in-depth appendix, additional research to enhance the existing sections, and a new section focusing on the influence of the shadow on both Tarot itself and the other mediums Tarot influences.

4. Physical Activity Experiences of Individuals Living With a Traumatic Brain Injury: A Qualitative Research Exploration.

Author

Self, Megan, Driver, Simon, Stevens, Laurel, and Warren, Ann Marie

Abstract

Traumatic brain injury (TBI) is a significant public health issue due to the incidence, complexity, and cost associated with treatment. The purpose of this study was to determine physical activity (PA) knowledge, attitudes, intentions, and barriers among individuals with a TBI undergoing outpatient rehabilitation. Seventeen participants completed a series of group interviews regarding their PA needs. A qualitative research design was adopted and trustworthiness was established through investigator triangulation of data. A cross-case analysis was completed to identify themes and conceptual patterns. The main themes identified were (a) an inability to differentiate between PA and physical therapy, (b) a limited knowledge of PA health benefits and the relationship to rehabilitation, and (c) an interest in participating in a PA based health promotion program. Future interventions should educate individuals about PA, the associated health benefits, and the role PA plays in the rehabilitation process. [ABSTRACT FROM AUTHOR]

Abstract

Pseudomonas aeruginosa can develop resistance to polymyxin and other cationic antimicrobial peptides. Previous work has shown that mutations in the PmrAB and PhoPQ regulatory systems can confer low to moderate levels of polymyxin resistance (MICs of 8 - 64 mg/L) in laboratory and clinical strains of this organism. To explore the role of PhoPQ in high-level clinical polymyxin resistance, P. aeruginosa strains with colistin MICs > 512 mg/L that had been isolated from cystic fibrosis patients treated with inhaled colistin (polymyxin E) were analyzed. Probable loss-of-function phoQ alleles found in these cystic fibrosis strains conferred resistance to polymyxin. Partial and complete suppressor mutations in phoP were identified in some cystic fibrosis strains with resistance-conferring phoQ mutations, suggesting that additional loci can be involved in polymyxin resistance in P. aeruginosa. Disruption of chromosomal phoQ in the presence of an intact phoP allele stimulated 4-amino-L-arabinose addition to lipid A and induced transcription from the promoter of the pmrH (arnB) operon, consistent with the known role of this lipid A modification in polymyxin resistance. These results indicate that phoQ loss-of-function mutations can contribute to high-level polymyxin resistance in clinical strains of P. aeruginosa.
