Psychosocial Difficulties (PSD) Experienced by People across Brain Disorders and the Implications for Occupational Therapy: A Cross-Sectional Study.

Psychosocial difficulties are defined as impairments in mental and body functions, activity limitations and participation restrictions, experienced in common across brain disorders. This cross-sectional study compared the psychosocial difficulties among people with Parkinson's disease (n = 61), schizophrenia (n = 84) and stroke (n = 70). The extent of difficulties was found to be similar across the three disorders in most of the domains studied. Psychosocial difficulties were also found to be associated with sociodemographic and illness related factors. The results challenge the brain disorder-specific approach to psychosocial difficulties commonly carried out in neurological and psychiatric research. Implications to occupational therapy are presented.

Proliferative and Nonproliferative Lesions of the Rat and Mouse Central and Peripheral Nervous Systems: New and Revised INHAND Terms.

Harmonization of diagnostic terminology used during the histopathologic analysis of rodent tissue sections from nonclinical toxicity studies will improve the consistency of data sets produced by laboratories located around the world. The INHAND Project (International Harmonization of Nomenclature and Diagnostic Criteria for Lesions in Rats and Mice) is a cooperative enterprise of 4 major societies of toxicologic pathology to develop a globally accepted standard vocabulary for proliferative and nonproliferative lesions in rodents. A prior manuscript (Toxicol Pathol 2012;40[4 Suppl]:87S-157S) defined multiple diagnostic terms for toxicant-induced lesions, common spontaneous and age-related changes, and principal confounding artifacts in the rat and mouse central nervous system (CNS) and peripheral nervous system (PNS). The current article defines 9 new diagnostic terms and updates 2 previous terms for findings in the rodent CNS and PNS, the need for which has become evident in the years since the publication of the initial INHAND nomenclature for findings in rodent neural tissues. The nomenclature presented in this document is also available electronically on the Internet at the goRENI website (http://www.goreni.org/).

Screening, assessment and management of type 2 diabetes mellitus in children and adolescents: Australasian Paediatric Endocrine Group guidelines.

INTRODUCTION: The incidence of type 2 diabetes mellitus has increased in children and adolescents due largely to the obesity epidemic, particularly in high risk ethnic groups. ß-Cell function declines faster and diabetes complications develop earlier in paediatric type 2 diabetes compared with adult-onset type 2 diabetes. There are no consensus guidelines in Australasia for assessment and management of type 2 diabetes in paediatric populations and health professionals have had to refer to adult guidelines. Recent international paediatric guidelines did not address adaptations to care for patients from Indigenous backgrounds. MAIN RECOMMENDATIONS: This guideline provides advice on paediatric type 2 diabetes in relation to screening, diagnosis, diabetes education, monitoring including targets, multicomponent healthy lifestyle, pharmacotherapy, assessment and management of complications and comorbidities, and transition. There is also a dedicated section on considerations of care for children and adolescents from Indigenous background in Australia and New Zealand. CHANGES IN MANAGEMENT AS A RESULT OF THE GUIDELINES: Published international guidelines currently exist, but the challenges and specifics to care for children and adolescents with type 2 diabetes which should apply to Australasia have not been addressed to date. These include: recommendations regarding care of children and adolescents from Indigenous backgrounds in Australia and New Zealand including screening and management; tighter diabetes targets (glycated haemoglobin, ≤ 48 mmol/mol [≤ 6.5%]) for all children and adolescents; considering the use of newer medications approved for adults with type 2 diabetes under the guidance of a paediatric endocrinologist; and the need to transition adolescents with type 2 diabetes to a diabetes multidisciplinary care team including an adult endocrinologist for their ongoing care.

Equity-informed social media COVID-19 risk communication strategies: a scoping review.

OBJECTIVES: The COVID-19 pandemic has had devastating worldwide impact but most prominent was its effect on marginalised, underserved and equity-deserving populations. Social media arose as an important platform from which health organisations could rapidly disseminate information to equity-deserving populations about COVID-19 risks and events, provide instructions on how to mitigate those risks, motivate compliance with health directives, address false information, provide the opportunity for engagement and immediate feedback. The objective of this scoping review was to synthesise the academic and grey literature on equity-informed social media risk communication strategies developed during the pandemic. DESIGN: The review followed the Arksey and O'Malley framework and focused on the research question: What are the promising principles, processes, and practices for producing equity-informed social media risk communications? DATA SOURCES: CINAHL Complete, MEDLINE (OVID), Business Source Complete, EMBASE database OVID, Scopus and PubMed's curated COVID-19 literature hub: LitCovid, PsycINFO OVID were searched using terms related to access to health services, social media, risk communication, misinformation, community engagement, infectious disease, pandemics and marginalisation, supplemented by grey literature from relevant health organisations. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Studies were eligible if the population of interest was an equity-deserving population, the concept discussed was COVID-19 risk communication and the article was published in English between January 2019 and December 2022. DATA EXTRACTION AND SYNTHESIS: COVIDENCE facilitated screening and extraction. Charted data were thematically analysed following Braun and Clarke's phased process. Preliminary findings were collaboratively discussed with representatives from health agencies and community organisations focused on serving equity-deserving groups. RESULTS: 12 studies were included. In terms of principles and process, studies emphasised the need to collaboratively create plans for message construction and targeted dissemination using a risk communication framework, capitalise on access to community resources and pre-established communication mediums and be considerate of population-specific needs and concerns. Practice entails careful consideration of communication mediums, language usage, communication frequency and evaluation. CONCLUSION: This scoping review provides valuable insights for health agencies and community organisations in developing principles, processes and practices to equitably communicate risk information through social media. Engagement with stakeholders further refined and confirmed the findings, offering insights for future crisis communication strategies.

A systematic review of upper extremity outcome measures assessed in randomized controlled trials of post stroke upper extremity rehabilitation over time.

BACKGROUND: The heterogeneity in outcome measures of post stroke rehabilitation trials suggests the need for consensus approach in stroke recovery measurement. To reach this aim, it is important to understand the past and current use of outcome measures in randomized control trials (RCTs) of stroke rehabilitation. OBJECTIVE: To systematically review RCTs of post stroke UE rehabilitation interventions to understand the use of UE outcome measures in research and their changes over time. METHODS: CINAHL, Embase, PubMed, Scopus and Web of Science were searched from 1960 to 1 April 2021. Studies were eligible for inclusion if they (1) were RCTs or crossovers published in English (2) ≥50% of participants were affected by stroke, 3) included adults ≥ 18 years old, and (4) applied an intervention to the hemiparetic UE as the primary objective of the study. RESULTS: 1,276 RCTs met inclusion criteria, and 112 different outcome measures were identified. Outcome measures were classified according to the International Classification of Functioning, Disability and Health (ICF) framework. Outcome measures most frequently assessed body function and structure (n = 1,692), followed by activities (n = 1,572) and participation (n = 162). The most used outcome measures were the Fugl-Meyer Assessment (n = 619), the modified Ashworth Scale (n = 255), Action Research Arm Test (n = 211), Wolf Motor Function Test (n = 184), and Box and Block Test (n = 178). CONCLUSIONS: Understanding the breadth of outcome measures that have been used over time emphasizes the need for proposed standardization of outcome measures but also the need to adjust and expand consensus recommendations based on past and ongoing research trends.

Intramuscular Botulinum Neurotoxin Serotypes E and A Elicit Distinct Effects on SNAP25 Protein Fragments, Muscular Histology, Spread and Neuronal Transport: An Integrated Histology-Based Study in the Rat.

Botulinum neurotoxins E (BoNT/E) and A (BoNT/A) act by cleaving Synaptosome-Associated Protein 25 (SNAP25) at two different C-terminal sites, but they display very distinct durations of action, BoNT/E being short acting and BoNT/A long acting. We investigated the duration of action, spread and neuronal transport of BoNT/E (6.5 ng/kg) and BoNT/A (125 pg/kg) after single intramuscular administrations of high equivalent efficacious doses, in rats, over a 30- or 75-day periods, respectively. To achieve this, we used (i) digit abduction score assay, (ii) immunohistochemistry for SNAP25 (N-ter part; SNAP25N-ter and C-ter part; SNAP25C-ter) and its cleavage sites (cleaved SNAP25; c-SNAP25E and c-SNAP25A) and (iii) muscular changes in histopathology evaluation. Combined in vivo observation and immunohistochemistry analysis revealed that, compared to BoNT/A, BoNT/E induces minimal muscular changes, possesses a lower duration of action, a reduced ability to spread and a decreased capacity to be transported to the lumbar spinal cord. Interestingly, SNAP25C-ter completely disappeared for both toxins during the peak of efficacy, suggesting that the persistence of toxin effects is driven by the persistence of proteases in tissues. These data unveil some new molecular mechanisms of action of the short-acting BoNT/E and long-acting BoNT/A, and reinforce their overall safety profiles.

Measuring Health Care Work-Related Contextual Factors: Development of the McGill Context Tool.

INTRODUCTION: Contextual factors can influence healthcare professionals' (HCPs) competencies, yet there is a scarcity of research on how to optimally measure these factors. The aim of this study was to develop and validate a comprehensive tool for HCPs to document the contextual factors likely to influence the maintenance, development, and deployment of professional competencies. METHODS: We used DeVellis' 8-step process for scale development and Messick's unified theory of validity to inform the development and validation of the context tool. Building on results from a scoping review, we generated an item pool of contextual factors articulated around five themes: Leadership and Agency, Values, Policies, Supports, and Demands. A first version of the tool was pilot tested with 127 HCPs and analyzed using the classical test theory. A second version was tested on a larger sample (n = 581) and analyzed using the Rasch rating scale model. RESULTS: First version of the tool: we piloted 117 items that were grouped as per the themes related to contextual factors and rated on a 5-point Likert scale. Cronbach alpha for the set of 12 retained items per scale ranged from 0.75 to 0.94. Second version of the tool included 60 items: Rasch analysis showed that four of the five scales (ie, Leadership and Agency, Values, Policies, Supports) can be used as unidimensional scales, whereas the fifth scale (Demands) had to be split into two unidimensional scales (Demands and Overdemands). DISCUSSION: Validity evidence documented for content and internal structure is encouraging and supports the use of the McGill context tool. Future research will provide additional validity evidence and cross-cultural translation.

The Definitions and Conceptualizations of the Practice Context in the Health Professions: A Scoping Review.

INTRODUCTION: Health care professionals work in different contexts, which can influence professional competencies. Despite existing literature on the impact of context on practice, the nature and influence of contextual characteristics, and how context is defined and measured, remain poorly understood. The aim of this study was to map the breadth and depth of the literature on how context is defined and measured and the contextual characteristics that may influence professional competencies. METHODS: A scoping review using Arksey and O'Malley's framework. We searched MEDLINE (Ovid) and CINAHL (EBSCO). Our inclusion criteria were studies that reported on context or relationships between contextual characteristics and professional competencies or that measured context. We extracted data on context definitions, context measures and their psychometric properties, and contextual characteristics influencing professional competencies. We performed numerical and qualitative analyses. RESULTS: After duplicate removal, 9106 citations were screened and 283 were retained. We compiled a list of 67 context definitions and 112 available measures, with or without psychometric properties. We identified 60 contextual factors and organized them into five themes: Leadership and Agency, Values, Policies, Supports, and Demands. DISCUSSION: Context is a complex construct that covers a wide array of dimensions. Measures are available, but none include the five dimensions in one single measure or focus on items targeting the likelihood of context influencing several competencies. Given that the practice context plays a critical role in health care professionals' competencies, stakeholders from all sectors (education, practice, and policy) should work together to address those contextual characteristics that can adversely influence practice.

Proliferative and nonproliferative lesions of the rat and mouse central and peripheral nervous systems.

Harmonization of diagnostic nomenclature used in the pathology analysis of tissues from rodent toxicity studies will enhance the comparability and consistency of data sets from different laboratories worldwide. The INHAND Project (International Harmonization of Nomenclature and Diagnostic Criteria for Lesions in Rats and Mice) is a joint initiative of four major societies of toxicologic pathology to develop a globally recognized nomenclature for proliferative and nonproliferative lesions in rodents. This article recommends standardized terms for classifying changes observed in tissues of the mouse and rat central (CNS) and peripheral (PNS) nervous systems. Sources of material include academic, government, and industrial histopathology databases from around the world. Covered lesions include frequent, spontaneous, and aging-related changes as well as principal toxicant-induced findings. Common artifacts that might be confused with genuine lesions are also illustrated. The neural nomenclature presented in this document is also available electronically on the Internet at the goRENI website (http://www.goreni.org/).

Is Piperacillin-Tazobactam an Appropriate Empirical Agent for Hospital-Acquired Sepsis and Community-Acquired Septic Shock of Unknown Origin in Australia?

Early appropriate empirical antibiotics are critical for reducing mortality in sepsis. For hospital-acquired sepsis of unknown origin in Australia, piperacillin-tazobactam (TZP) is recommended as an empirical therapy. Anecdotally, some institutions also use TZP for community-acquired septic shock. This narrative review aimed to scrutinise the appropriateness of TZP as an empirical agent for undifferentiated hospital-acquired sepsis and community-acquired septic shock. An online database (Medline) was searched for relevant studies in adults published in the last 10 years. Studies were included if they addressed separately reported clinical outcomes related to a relevant aspect of TZP therapy in sepsis. Of 290 search results, no studies directly addressed the study aim. This review therefore explores several themes that emerged from the contemporary literature, all of which must be considered to fully interrogate the appropriateness of TZP use in this context. This review reveals the paucity and low quality of evidence available for TZP use in sepsis of unclear origin, while demonstrating the urgent need and equipoise for an Australian audit of TZP use in patients with sepsis of unknown origin.

Histomorphology and vascular lesions in dorsal rat skin used as injection sites for a subcutaneous toxicity study.

Subcutaneous injection of pharmaceutical compounds into the dorsal skin of rats is common in preclinical and nonclinical studies. However, no detailed histologic description of this anatomic location has been published to date. Following the observation of vascular lesions in the dorsum of rats in a thirteen-week toxicity study, a complementary study was performed on untreated Sprague-Dawley rats to evaluate the normal histology of the skin and subcutis, the potential effect of chronic subcutaneous injection on the morphology of the skin and its vasculature, and the spontaneous vascular pathology in the areas used as injection sites in the principal study. This study showed that saline injection did not fundamentally alter the morphology of the injection sites used for the principal study. Skin thickness was greater in males than in females. Although acellular intimal thickening occurred spontaneously in the dorsal skin of untreated males and females, only males had a spontaneous incidence of intimal hyperplasia. No site predilection for intimal lesions was apparent for either sex. Saline injection, or the physical trauma of injection, may induce intimal hyperplasia; males appear more likely to develop the lesion than do females. It is possible that acellular intimal thickening can progress to intimal hyperplasia under appropriate conditions.

Recommendations for pathology peer review.

Pathology peer review verifies and improves the accuracy and quality of pathology diagnoses and interpretations. Pathology peer review is recommended when important risk assessment or business decisions are based on nonclinical studies. For pathology peer review conducted before study completion, the peer-review pathologist reviews sufficient slides and pathology data to assist the study pathologist in refining pathology diagnoses and interpretations. Materials to be reviewed are selected by the peer-review pathologist. Consultations with additional experts or a formal (documented) pathology working group may be used to resolve discrepancies. The study pathologist is solely responsible for the content of the final pathology data and report, makes changes resulting from peer-review discussions, initiates the audit trail for microscopic observations after all changes resulting from peer-review have been made, and signs the final pathologist's report. The peer-review pathologist creates a signed peer-review memo describing the peer-review process and confirming that the study pathologist's report accurately and appropriately reflects the pathology data. The study pathologist also may sign a statement of consensus. It is not necessary to archive working notes created during the peer-review process.

International recommendations for training future toxicologic pathologists participating in regulatory-type, nonclinical toxicity studies.

The International Federation of Societies of Toxicologic Pathologists (IFSTP) proposes a common global framework for training future toxicologic pathologists who will support regulatory-type, nonclinical toxicology studies. Optimally, trainees should undertake a scientific curriculum of at least five years at an accredited institution leading to a clinical degree (veterinary medicine or medicine). Trainees should then obtain four or more years of intensive pathology practice during a residency and/or on-the-job "apprenticeship," at least two years of which must be focused on regulatory-type toxicologic pathology topics. Possession of a recognized pathology qualification (i.e., certification) is highly recommended. A nonclinical pathway (e.g., a graduate degree in medical biology or pathology) may be possible if medically trained pathologists are scarce, but this option is not optimal. Regular, lifelong continuing education (peer review of nonclinical studies, professional meetings, reading, short courses) will be necessary to maintain and enhance one's understanding of current toxicologic pathology knowledge, skills, and tools. This framework should provide a rigorous yet flexible way to reliably train future toxicologic pathologists to generate, interpret, integrate, and communicate data in regulatory-type, nonclinical toxicology studies.

Assessing patient understanding of their antimicrobial treatment: How are we doing and how might we improve?

BACKGROUND: The Antimicrobial Stewardship Clinical Care Standard states that patients should receive certain information about their antimicrobial therapy. How well the patient communication recommendations of the standard are followed in clinical practice is not well established. The aim of this pilot quality improvement study was to assess current practices around communication with hospitalised patients about their antimicrobial therapy, to determine compliance with current recommendations, and develop and implement quality improvement actions focused on patient communication for antimicrobial stewardship in Australia. METHODS: Adult inpatients receiving one or more antimicrobials for greater than 72 h were recruited. A survey was conducted to assess rates of compliance with requirements to inform patients about the indication, duration and potential side effects of current antimicrobial therapy; modes of delivery of information; and rates of patient satisfaction with the information provided. A paper-based survey was conducted on the general medical, infectious diseases, geriatric evaluation and management, and rehabilitation wards in a 500-bed tertiary Australian hospital. A sample size of 50 was determined as adequate for a baseline analysis of patient communication practices and the development of quality improvement resources and actions. Responses to categorical questions were analysed quantitatively, with additional feedback from patients was collated and analysed qualitatively. RESULTS: A total of 54 patients were surveyed. A majority (83%) of patients had been informed that they were taking antimicrobials, and, of these, 96% said they knew the indication, 18% were informed of potential side effects, and 36% knew the duration. Only 22% were informed of the review plan and 27% knew if antimicrobials would be continued on discharge. Written information was given to 11% of patients. Over half (62%) of patients either wanted more information or had concerns about their antimicrobial therapy. Patients reported difficulty in obtaining information. Fifty-eight percent of patients received antimicrobial information from doctors, 13% from nurses and 12% from pharmacists. CONCLUSIONS: This study identified gaps in communication with patients regarding in-hospital antimicrobial therapy, and highlighted the need for development and delivery of local quality improvement activities to address this gap.

Measuring antimicrobial prescribing quality in outpatient parenteral antimicrobial therapy (OPAT) services: development and evaluation of a dedicated national antimicrobial prescribing survey.

BACKGROUND: Antimicrobial stewardship programmes are important in driving safety and quality of antimicrobial prescribing. The National Antimicrobial Prescribing Survey (NAPS) is a point-prevalence audit of inpatient antimicrobial prescribing in Australian hospitals. OBJECTIVES: To design and adapt the NAPS tool for use in the outpatient parenteral antimicrobial therapy (OPAT) and hospital-in-the-home (HITH) setting. METHODS: An inter-disciplinary working group with expertise in OPAT and HITH services was established to adapt the NAPS template for use in the OPAT setting-called HITH-NAPS. This was initially trialled in 5 HITH services, subsequently adapted following participant feedback, then offered nationally to 50 services in 2017. RESULTS: There were 1154 prescriptions for 715 patients audited via the HITH-NAPS. The most common antimicrobials prescribed were cefazolin (22%), flucloxacillin (12%), piperacillin/tazobactam (10%) and ceftriaxone (10%). The most common infections treated were cellulitis (30%) and respiratory tract infections (14%). Eighty-seven percent of prescriptions were assessed as appropriate, 11% inappropriate and 2% not assessable. Prolonged durations of antimicrobials and unnecessarily broad-spectrum antibiotics were used in 9% of prescriptions. CONCLUSIONS: The HITH-NAPS pilot project revealed that auditing of this type is feasible in HITH. It showed that antibiotic use in these HITH services was generally appropriate, but there are some areas for improvement. A national OPAT/HITH-NAPS can facilitate benchmarking between services, identify potentially inappropriate prescribing and help guide quality improvement.

Myocardial fibrosis in a horse with polymorphic ventricular tachycardia observed during general anesthesia.

Ventricular dysrhythmias are more commonly associated with myocardial disease than are supraventricular dysrhythmias. Management of arrhythmias under general anesthesia is difficult because of the dysrhythmogenic effects of the anesthetic drugs. This report describes a severe ventricular dysrhythmia observed in a pony under general anesthesia, with a severe and old myocardial fibrosis found on postmortem examination.

Harmonization of immunotoxicity guidelines in the ICH process--pathology considerations from the guideline Committee of the European Society of Toxicological Pathology (ESTP) .

As part of the ICH process of harmonization of testing guidelines for immunotoxicity, the European Society of Toxicologic Pathology (ESTP) has contributed to the scientific discussion on methods and evaluation of immunotoxicity studies with technical and scientific recommendations on toxicologic pathology. The weighing and sampling of immune organs is discussed taking into consideration specifically the value of lymph node weighing and the selection of appropriate lymph nodes for the detection of local and systemic effects. The different techniques of bone marrow preparation are considered for routine and extended investigations. Criteria are given for the gross and histopathological detection of effects in Peyer's patches. For the histopathological evaluation it is strongly recommended that each compartment within the different lymphoid organs is investigated separately and semiquantitatively since this approach has shown to increase the sensitivity and specificity of immunohistopathology.
