* Investigation of the Physical, Chemical and Microbiological Stability of Losartan Potassium 5 mg/mL Extemporaneous Oral Liquid Suspension.
- Extemporaneous oral liquid preparations are commonly used when there is no commercially available dosage form for adjustable dosing. In most cases, there is a lack of stability data to allow for an accurately assigned shelf life and storage conditions to give greater confidence of product safety and efficacy over its shelf life. The aim of this study was to evaluate the physical, chemical and microbiological stability of an extemporaneous oral liquid suspension of losartan potassium, 5 mg/mL, used to treat paediatric hypertension in Our Lady's Children's Hospital Crumlin, Ireland. The losartan content of extemporaneous oral suspensions, prepared with and without addition of water, was measured by UV and confirmed by HPLC analysis. Suspensions were stored at 4 °C and room temperature (RT) and were monitored for changes in; pH, colour, odour, re-dispersibility, Total Aerobic Microbial Count, Total Yeast and Mould Count and absence of E. coli. Results showed that suspensions prepared by both methods, stored at 4 °C and RT, were physically and microbiologically stable over 28 days. Initial losartan content of all suspensions was lower than expected at 80-81% and did not change significantly over the 28 days. HPLC and NMR did not detect degradation of losartan in the samples. Suspensions prepared in water showed 100% losartan content. The reduced initial losartan content was confirmed by HPLC and was related to the acidic pH of the suspension vehicle. Physiochemical properties of the drug are important factors for consideration in the selection of suspension vehicle for extemporaneous compounding of oral suspensions as they can influence the quality, homogeneity and efficacy of these preparations.

* Imbuing Occupations with Spiritual Significance Fosters Experiences of Hope.
- In theories of occupational therapy, occupation serves as a conduit for creating meaning and well-being. A crucial component of occupational therapy is developing and maintaining hope of clients during periods of major difficulty. Understanding the relationship between hope and occupation can prove helpful in stressful situations, such as caring for children with chronic illnesses. The aim of the present study was to identify occupations that foster experiences of hope among mothers of adult children with mental illness. A qualitative approach, informed by a constructivist framework and thematic analysis, was used to interpret and explicate relevant occupation-related themes that fostered hope in four mothers. The mother-participants reported engaging in various occupations, yet only occupations that were imbued with spiritual significance fostered experiences of hope. This study brings to the forefront of occupational therapy discourse the issue of spiritual connectedness as a potential link between occupations and hope.
