Polyurethane Elastomers as Maxillofacial Prosthetic Materials

A series of polyurethane elastomers based on an aliphatic diisocyanate and a polyether macroglycol was polymerized with various crosslink densities and OH/NCO ratios. Stoichiometries yielding between 8,600 and 12,900 gm/ mole/crosslink and an OH/NCO ratio of 1.1 resulted in polymers with the low modulus, yet high strength and elongation necessary for maxillofacial applications.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68299/2/10.1177_00220345780570040501.pd

Carbon membranes for oxygen enriched air – Part I: Synthesis, performance and preventive regeneration

Chemisorption of oxygen on the active sites of carbon layers limits the use of carbon membranes in air separation application. A novel online electrical regeneration method was applied to prevent the active sites on carbon surface to be reacting with O2 while the membrane was in operation. This method reduced the aging effect and the membrane showed relative stable performance with only 20% loss in O2 permeability and 28% increase in O2/N2 selectivity, over the period of 135 days using various feeds containing H2S, n-Hexane and CO2-CH4 gas. The carbon membranes reported here were produced at the pilot-scale facility by the carbonization of regenerated cellulose under optimized conditions to achieve good air separation properties. The permeation properties of the membranes were tested by single gas separation experiments at 5 bar feed pressure (50 mbar permeate) and temperature range 20–68 °C. It was observed that O2 permeability is increasing exponentially with increase in operating temperature without significant loss in the O2/N2 selectivity. The O2 permeability of 10 Barrer (1 Barrer = 2.736E − 09 m3(STP)m/m2 bar h) with O2/N2 selectivity of 19 was achieved at 68 °C. Thermal (80 °C), chemical (propylene) and online-electrical (10 V DC) regeneration approaches were studied to lessen the aging effect on carbon membranes.acceptedVersion© 2018.

Promoting Intensive Transitions for Children and Youth with Medical Complexity from Paediatric to Adult Care: the PITCare study—protocol for a randomised controlled trial

Introduction Children with medical complexity (CMC) have chronic, intensive care needs managed by many healthcare practitioners. Medical advances have enabled CMC to survive well into adulthood. However, the availability of supports as CMC transition into the adult care system remain suboptimal, contributing to poor care coordination, and discontinuity. Promoting Intensive Transitions for Children and Youth with Medical Complexity from Paediatric to Adult Care (PITCare) aims to assess whether intensive patient and caregiver-oriented transition support beyond age 18 will improve continuity of care for CMC compared with usual care.Methods and analysis This is a pragmatic superiority randomised controlled trial in a parallel group, two-arm design with an embedded qualitative component. CMC turning 17.5 years old will be recruited (n=154), along with their primary caregiver. Participants randomised to the intervention arm will be provided with access to a multidisciplinary transition team who will support patients and caregivers in care planning, integration with an adult primary care provider (PCP), adult subspecialty facilitation and facilitation of resource supports for 2 years. Outcomes will be measured at baseline, 12 and 24 months. The primary outcome measure is successful transfer completion, defined as continuous care in the 2 years after age 18 years old. Secondary outcomes include satisfaction with transitional care, self-management, care coordination, healthcare service use, caregiver fatigue, family distress, utility and cost-effectiveness. Qualitative interviews will be conducted to explore the experiences of patients, caregivers, the transition team, and healthcare providers with the PITCare intervention.Ethics and dissemination Institutional approval was obtained from the Hospital for Sick Children Research Ethics Board. Our findings and resources will be shared with child health policymakers and transitions advocacy groups provincially, nationally, and internationally.Trial registration number ClinicalTrials.gov, US National Library of Medicine, National Institutes of Health, #NCT06093386
