Premature bone resorption and remodeling by osteoclasts can limit the longevity of implant fixation and recovery time. Orally administered bisphosphonates (BPs) have been used to inhibit osteoclast action at the implant/bone interface. Ideally, these should be delivered at the interface with the osteoblast-active hydroxyapatite (HA) for maximum effect. This investigation introduces a novel BP loading technique to achieve improved BP release from a simulated body fluid-grown HA (SBF-HA) with the aim of improving implant fixation. A solution co-precipitation technique incorporates the BP (pamidronate) into a thin SBF-HA coating. Surface analysis, using X-ray photoelectron spectroscopy (XPS), of the resultant coating was employed to confirm the presence of the adsorbed BP on the surface of SBF-HA. XPS analysis was also used to determine the optimal adsorption process. Osteoclast cell culture experiments confirmed the biological effectiveness of BP adsorption and proved that the pamidronate was biologically active, causing both decreased osteoclast numbers and decreased resorption.

IntroductionYoung children with bilateral cerebral palsy (BCP) often experience difficulties with gross motor function, manual ability and posture, impacting developing independence in daily life activities, participation and quality of life. Hand Arm Bimanual Intensive Training Including Lower Extremity (HABIT-ILE) is a novel intensive motor intervention integrating upper and lower extremity training that has been developed and tested in older school-aged children with unilateral and BCP. This study aims to compare an adapted preschool version of HABIT-ILE to usual care in a randomised controlled trial.Methods and analysis60 children with BCP aged 2–5 years, Gross Motor Function Classification System (GMFCS) II–IV will be recruited. Children will be stratified by GMFCS and randomised using concealed allocation to either receive Preschool HABIT-ILE or usual care. Preschool HABIT-ILE will be delivered in groups of four to six children, for 3 hours/day for 10 days (total 30 hours). Children receiving Preschool HABIT-ILE be provided a written home programme with the aim of achieving an additional 10 hours of home practice (total dose 40 hours). Outcomes will be assessed at baseline, immediately following intervention and then retention of effects will be tested at 26 weeks. The primary outcome will be the Peabody Developmental Motors Scales–Second Edition to evaluate gross and fine motor skills. Secondary outcomes will be gross motor function (Gross Motor Function Measure-66), bimanual hand performance (Both Hands Assessment), self-care and mobility (Pediatric Evaluation of Disability Inventory-Computer Adapted Test), goal attainment (Canadian Occupational Performance Measure), global performance of daily activities (ACTIVLIM-CP), cognition and adaptive function (Behavior Rating Inventory of Executive Function—Preschool Version), habitual physical activity (ActiGraph GT3X+) and quality of life (Infant Toddler Quality of Life Questionnaire and Child Health Utility Index-9). Analyses will follow standard principles for RCTs using two-group comparisons on all participants on an intention-to-treat basis. Comparisons between groups for primary and secondary outcomes will be conducted using regression models.Ethics and disseminationEthics approval has been granted by the Medical Research Ethics Committee Children’s Health Queensland Hospital and Health Service Human Research Ethics Committee (HREC/19/QCHQ/59444) and The University of Queensland (2020000336/HREC/19/QCHQ/59444).Trial registration numberACTRN126200000719.

ObjectiveIncontinence is one of the main reasons for institutionalisation into residential aged care. It is linked with increased falls, skin breakdown, depression, social isolation and impaired quality of life. Studies over the past decade have demonstrated poor‐quality incontinence care, which has led to ongoing development of best practice guidelines and educational resources. This study investigated current practices, and staff and resident experiences with continence assessment and management, in comparison with best practice guidelines.MethodsThis concurrent mixed methods study was conducted in a 120‐bed residential aged care home. Secondary analysis of data from clinical records provided a snapshot of how continence was assessed and managed. Semistructured interviews with four staff and five residents explored their experiences to understand the impact of current practice on resident emotional well‐being. Mixing methods allowed for comparison between quantitative and qualitative findings, enabling a deeper understanding.ResultsFindings from the two data sets were highly congruent and identified: (1) lack of communication with residents and family members about continence needs; (2) heavy reliance on product usage and limited other conservative strategies; (3) staff frustration at inability to respond to calls in a timely manner; and (4) positive staff–resident relationships protect resident emotional well‐being.ConclusionsCurrent practices are not consistent with best practice guidelines, which raises the question as to why nothing has changed. We argue that a stronger focus on implementation underpinned by a relationship‐centred approach is required to improve continence care practices among residential care staff, and the quality of life for adults living with incontinence.
