Enhancing occupational therapy service provision with military veterans through policy reform: Findings from a national survey.

INTRODUCTION: Almost half a million Australians have served with the Australian Defence Force. Given the high prevalence of physical and mental health conditions and complexity of civilian life adjustment after military service, high-quality occupational therapy services are critical. However, there is limited description of occupational therapy service provision to individuals funded by the Australian Department of Veterans' Affairs to inform government policy. The aim of this study was to describe the practice of Australian occupational therapists working with former service members and identify opportunities to enhance practice and policy. METHODS: A cross-sectional study using an online survey was conducted to collect information from occupational therapists providing services to Department of Veterans' Affairs clients. Frequency analyses were performed to describe quantitative data. Qualitative data were analysed using thematic analysis. No consumer or community involvement occurred. RESULTS: Participants included 123 Australian occupational therapists residing in metropolitan (47%), regional (28%) and rural/remote (23%) areas. Most occupational therapists (69%) had over 15 years of clinical experience and worked in private practice (87%). Common interventions included home modifications, equipment prescription and assistive technology (77%), goal-oriented rehabilitation (16%) and activities of daily living or function assessments and education (13%). Three themes describing practice issues were identified: (1) Service provision as rewarding yet underfunded, (2) Administrative complexity and lack of understanding of the occupational therapy role and (3) Need for specialist professional development opportunities. CONCLUSION: Australian occupational therapists are providing a range of services to Department of Veterans' Affairs clients although mostly relating to physical conditions. Occupational therapy practice with former Australian Defence Force members should be expanded to meet their diverse and complex needs. Further research and education are needed to support use of specialist knowledge and interventions. Advocacy by peak associations and policy reform are urgently required to ensure sustainable services, particularly in rural areas.

Assessing CRNA Knowledge of Local Anesthetic Systemic Toxicity Treatment.

Local anesthetic systemic toxicity (LAST) is a rare life-threatening adverse event. Due to the potential for devastating patient outcomes, it is crucial for anesthesia providers to understand appropriate LAST management. The primary aim of this study was to assess certified registered nurse anesthetist (CRNA) knowledge of the 2020 American Society of Regional Anesthesia and Pain Medicine (ASRA) LAST treatment guidelines. The secondary aim was to determine whether there was a relationship between the frequency of CRNAs' exposure to perioperative local anesthetic use and their knowledge level. A quantitative descriptive study and national American Association of Nurse Anesthetists electronic survey solicited practicing CRNAs. Survey findings revealed knowledge scores averaging 47.3% among 184 respondents. Almost all (97.8%) recognized the importance of early lipid emulsion administration. Over half (54.3%) were unaware of the recommended epinephrine dosing during LAST. No relationship was found between knowledge level and CRNAs' exposure to local anesthetics. Those who reported having immediate access to written or electronic guidelines in the event of LAST had significantly higher knowledge scores than those without access (P = .049). Implementing cognitive aids may help bridge knowledge gaps identified in this study and ensure critical steps are not missed. Further studies examining the use of cognitive aids to improve CRNA knowledge of LAST management may be beneficial in the future.

Elimination of Screening Urine Cultures Prior to Elective Joint Arthroplasty.

Discontinuing routine processing of screening urine cultures prior to elective joint arthroplasty resulted in substantial reduction in urine cultures ordered and antimicrobial prescriptions for asymptomatic bacteriuria, without any significant impact on incidence of prosthetic joint infection. This simple change would be scalable across institutions with potential for significant healthcare savings.

Hybrid follicular cyst (pilomatrical and infundibular) arising within a sebaceous nevus.

A 7-year-old girl presented with a 3-month history of a small blue-brown papule arising within a large sebaceous nevus on her temporal scalp. A punch excision was performed that demonstrated a hybrid follicular cyst. The majority of the cyst wall displayed pilomatrical differentiation consisting of basaloid matrical-type cells with luminal shadow cell keratinization. The matrical epithelium displayed strong membranous, cytoplasmic, and nuclear staining for ß-catenin. Only a small component of the wall displayed infundibular differentiation. These findings were consistent with a hybrid follicular cyst predominantly displaying pilomatrical differentiation with only a small component of infundibular lining. The most common tumors arising within sebaceous nevi are the syringocystadenoma papilliferum and trichoblastoma. Follicular cysts with infundibular (sebaceous cyst) and trichilemmal (pilar cyst) differentiation are exceedingly common, although their development within sebaceous nevi appears to be rare. We report a rare case of a hybrid follicular cyst with matrical differentiation occurring within a sebaceous nevus.

A comparison of mass spectrometry based hydrogen deuterium exchange methods for probing the cyclophilin A cyclosporin complex.

Direct infusion electrospray ionisation mass spectrometry (DI-ESI-MS) techniques provide an increasingly popular route to determine quantitative information on protein-protein and protein-ligand interactions. When combined with hydrogen deuterium exchange (HDX), details on protein stability and complex conformation can be obtained; however, complexes retained by ESI-MS are not always representative of those in solution and care must be taken in interpreting gas phase results. Zhu et al. [1] and Powell and Fitzgerald [2] have outlined LC-MS based techniques to probe the solution phase properties of the protein-ligand system in question. We here have taken the well characterised soluble immunophilin protein cyclophilin A, and examined it in complex with its endogenous ligand cyclosporin A. This ligand is widely used as an immunosuppressant following organ transplant, and the complex provides a basis for drug discovery efforts. We have used direct infusion, coupled with HDX, gas phase HDX and also the LC-HDX techniques PLIMSTEX and SUPREX. Results from each of these four HDX methodologies are presented here and discussed critically. From our direct infusion we find that there are 2 observable hydrogen populations in the protein, a very fast exchanging population, and a slower group. The exchange rate of both is lowered in the presence of the ligand. For PLIMSTEX we find a K(d) for ligand binding of 321 ± 128 nM, which is within one order of magnitude of values previously reported. SUPREX under a variety of conditions provides a range of K(d) values, but when we average these for experimental error we obtain a K(d) of 7.11 ± 0.29 nM which agrees well with measurements from other studies including via SUPREX. Finally gas phase HDX of the native complex shows more than 3 distinct populations of exchangeable hydrogens, for both the apo- and the holo protein consistent with an unfolding and refolding of the protein in the gas phase. The different techniques are compared with respect to the advantages and disadvantages they bring to the study of this protein-ligand system.

Positive urine cultures: A major cause of inappropriate antimicrobial use in hospitals?

INTRODUCTION: Urine specimens are among the most common samples submitted for culture to microbiology laboratories. The objectives of the present study were to describe the indications for obtaining urine cultures in a cohort of hospitalized patients, and to determine the appropriateness of antimicrobial therapy in response to urine culture results. METHODS: The study was performed at a teaching hospital with an adjoining long-term care facility from June 1 to July 31, 2006. The medical records of nonpregnant adult patients with and without bacteriuria were reviewed. A symptomatic urinary tract infection was defined as the presence of bacteriuria in a patient with fever or urinary symptoms; asymptomatic bacteriuria was defined as bacteriuria without urinary symptoms and no infection evident at another site. RESULTS: Medical records of 335 eligible patients (64% male; mean age 68 years) were reviewed, including all 137 with bacteriuria, and 198 with negative urine cultures. In total, 51% of the urine specimens were obtained from an indwelling urinary catheter, and 28% were voided urine samples. Confusion (57%) and fever (36%) were the most common indications noted for obtaining the urine cultures. Only 34 patients (25% of those with positive urine cultures) met the criteria for a symptomatic urinary tract infection; 67 (49%) had asymptomatic bacteriuria and 36 (26%) had infection at a nonurinary site. Of those with asymptomatic bacteriuria, 64% received antimicrobial therapy for a total of 347 days. Confused patients with asymptomatic bacteriuria were more likely to be treated than were bacteriuric patients without altered mental status (OR 1.8, 95% CI 1.2 to 4.1; P=0.03). CONCLUSIONS: Urine cultures are frequently obtained from hospitalizedpatients,evenintheabsenceofurinarysymptoms.Asymptomatic bacteriuria is often treated in these patients, and accounts for a substantial burden of inappropriate antimicrobial use in hospitals. Effective strategies to improve urine culture ordering and antimicrobial utilization in hospitals need to be implemented.
