Evaluation of MSOT students' didactic knowledge and practice vs. real-time performance in manual patient transfers.

BACKGROUND: Due to the nature of its occupations, the healthcare industry recognizes that manually lifting, transferring, and handling patients are high-risk activities and leading factors for work-related musculoskeletal disorders. Research studies highlight that students are not receiving adequate training in manual patient transfer. OBJECTIVE: The objective of this study was to examine the procedural knowledge in patient transfer of second-year Master of Science in Occupational Therapy students and their practical skills in performing a manual patient transfer. METHODS: This observational, cross-sectional study included 23 occupational therapy students. Students completed the transfer technique knowledge assessment and subsequently performed a real-time manual patient transfer. RESULTS: No significant association was found between the participants' knowledge and performance in MPT (x2(2) = 0.578, p = 0.749). All students scored highly on the knowledge assessment (µ= 9.3, SD =±1.02); however, the performance on real-time manual patient transfer was moderate (µ= 11.57, SD =±3.37) for the majority of students. CONCLUSION: A gap exists between the results of students' knowledge and practice versus real-time performance in manual patient transfer. The practical training students receive on manual patient transfers in the academic setting may not equip them with the necessary skills and techniques to perform safe transfers.

Brief Report: Prevalence and Severity of Auditory Sensory Over-Responsivity in Autism as Reported by Parents and Caregivers.

Auditory sensory over-responsivity (aSOR) is a frequently reported sensory feature of autism spectrum disorders (ASD); however, there is little consensus regarding its prevalence and severity. This cross-sectional study uses secondary data from the Autism Diagnostic Interview-Revised (ADI-R; Item 72: undue sensitivity to noise) housed in the US National Institute of Mental Health Data Archives to identify prevalence and severity of aSOR. Of the 4104 subjects with ASD ages 2-54 (M = 9, SD = 5.8) who responded to item 72, 60.1% (n = 1876) had aSOR currently (i.e., point prevalence) and 71.1% (n = 2221) reported having aSOR ever (i.e., lifetime prevalence). aSOR prevalence and severity were affected by age, but there were no associations with sex.

Chemical vapour deposition of Fe-N-C oxygen reduction catalysts with full utilization of dense Fe-N4 sites.

Replacing scarce and expensive platinum (Pt) with metal-nitrogen-carbon (M-N-C) catalysts for the oxygen reduction reaction in proton exchange membrane fuel cells has largely been impeded by the low oxygen reduction reaction activity of M-N-C due to low active site density and site utilization. Herein, we overcome these limits by implementing chemical vapour deposition to synthesize Fe-N-C by flowing iron chloride vapour over a Zn-N-C substrate at 750 °C, leading to high-temperature trans-metalation of Zn-N4 sites into Fe-N4 sites. Characterization by multiple techniques shows that all Fe-N4 sites formed via this approach are gas-phase and electrochemically accessible. As a result, the Fe-N-C catalyst has an active site density of 1.92 × 1020 sites per gram with 100% site utilization. This catalyst delivers an unprecedented oxygen reduction reaction activity of 33 mA cm-2 at 0.90 V (iR-corrected; i, current; R, resistance) in a H2-O2 proton exchange membrane fuel cell at 1.0 bar and 80 °C.

Evolution Pathway from Iron Compounds to Fe1(II)-N4 Sites through Gas-Phase Iron during Pyrolysis.

Pyrolysis is indispensable for synthesizing highly active Fe-N-C catalysts for the oxygen reduction reaction (ORR) in acid, but how Fe, N, and C precursors transform to ORR-active sites during pyrolysis remains unclear. This knowledge gap obscures the connections between the input precursors and the output products, clouding the pathway toward Fe-N-C catalyst improvement. Herein, we unravel the evolution pathway of precursors to ORR-active catalyst comprised exclusively of single-atom Fe1(II)-N4 sites via in-temperature X-ray absorption spectroscopy. The Fe precursor transforms to Fe oxides below 300 °C and then to tetrahedral Fe1(II)-O4 via a crystal-to-melt-like transformation below 600 °C. The Fe1(II)-O4 releases a single Fe atom that diffuses into the N-doped carbon defect forming Fe1(II)-N4 above 600 °C. This vapor-phase single Fe atom transport mechanism is verified by synthesizing Fe1(II)-N4 sites via "noncontact pyrolysis" wherein the Fe precursor is not in physical contact with the N and C precursors during pyrolysis.

An Exploratory Survey of Physical Rehabilitation Occupational Therapy Practice Patterns.

A computer-assisted survey was developed and administered to 66 occupational therapists working in adult physical rehabilitation to explore how and to what extent occupational therapists evaluate and treat medication management impairments. Approximately 90% of the sample evaluate and treat medication management, but only about 25% addressed medication management on a consistent basis. This suggests that current medication management service provision levels may be insufficient to meet clients' needs. Research is warranted to understand and improve occupational therapists' abilities to address medication management in practice.
