A polymer network architecture provides superior cushioning and lubrication of soft tissue compared to a linear architecture.

We report the relationships between linear vs. network polymer architecture and biomechanical outcomes including lubrication and cushioning when the polymers are applied to the surface of articulating knee cartilage. Aqueous formulations of the bioinspired polymer poly(2-methacryloyloxylethyl phosphorylcholine) (pMPC) exhibit tuneable rheological properties, with network pMPC exhibiting increased elasticity and viscosity compared to linear pMPC. Application of a polymer network, compared to a linear one, to articulating tissue surfaces reduces friction, lessens tissue strain, minimizes wear, and protects tissue - thereby improving overall tissue performance. Administration of the network pMPC to the middle carpal joint of skeletally mature horses elicits a safe response similar to saline as monitored over a 70 day period.

The impact of covid-19 on psychosocial well-being and learning for australian nursing and midwifery undergraduate students: a cross-sectional survey.

AIM: To explore the impact of COVID-19 on psychosocial well-being and learning for nursing and midwifery undergraduate students in an Australian university. BACKGROUND: The World Health Organization has reported a substantial psychological impact of COVID-19 on healthcare professionals to date. Evidence is lacking, however, regarding university nursing and midwifery students of the pandemic and its impact on their educational preparation and/or clinical placement during the COVID-19 pandemic. DESIGN: Cross-sectional survey of nursing and midwifery undergraduate students enrolled in the Bachelor of Nursing suite of courses from the study institution in August- September 2020. METHODS: A cross-sectional self-administered anonymous online survey was distributed to current nursing and midwifery undergraduate students. The survey included three open-ended questions; responses were thematically analysed. RESULTS: Of 2907 students invited, 637 (22%) responded with 288 of the respondents (45%) providing a response to at least one of the three open-ended questions. Three major themes associated with the impact of the pandemic on psychosocial well-being and learning were identified: psychosocial impact of the pandemic, adjustment to new modes of teaching and learning, and concerns about course progression and career. These themes were underpinned by lack of motivation to study, feeling isolated, and experiencing stress and anxiety that impacted on students' well-being and their ability to learn and study. CONCLUSIONS: Students were appreciative of different and flexible teaching modes that allowed them to balance their study, family, and employment responsibilities. Support from academic staff and clinical facilitators/mentors combined with clear and timely communication of risk management related to personal protective equipment (PPE) in a healthcare facility, were reported to reduce students' stress and anxiety. Ways to support and maintain motivation among undergraduate nursing and midwifery students are needed.

Enhancing Nursing and Midwifery Student Learning Through the Use of QR Codes.

A recent teaching and learning innovation using new technologies involves the use of quick response codes, which are read by smartphones and tablets. Integrating this technology as a teaching and learning strategy in nursing and midwifery education has been embraced by academics and students at a regional university.
