RESUMO
OBJECTIVE: This study examined etiological factors and symptom triggers of functional motor symptoms (FMS) or functional seizures (FS) and assessed potential relationships with relevant clinical features (i.e., functional symptoms, quality of life, and general functioning). METHODS: Seventeen participants with FMS or FS and 17 healthy control participants underwent an in-depth clinical interview and completed questionnaires assessing adverse life events, psychological and physical symptoms, alexithymia, autistic traits, illness perceptions, health-related quality of life (HRQoL), and work and social functioning. RESULTS: Participants with FMS or FS perceived various causes of the disorder, including physical symptoms (65%), emotional problems (53%), adverse life events (47%), and work-related factors (29%). Triggers of FMS and FS included physical activity or exertion (59%), stress and emotions (59%), sensory experiences (47%), and fatigue (41%). Compared with healthy control participants, participants with FMS or FS reported more adverse events during adolescence and higher levels of alexithymia, somatoform dissociation, psychological dissociation (disengagement, depersonalization, and derealization), anxiety, depression, and physical symptoms. Participants with FMS or FS had worse HRQoL than healthy control participants and impaired work and social functioning. There were inverse associations between HRQoL scores and somatoform dissociation, anxiety, and adverse life events. CONCLUSIONS: Participants with FMS or FS reported diverse biopsychosocial etiological factors and symptom triggers. Ongoing psychological symptoms and lifetime adverse experiences were associated with worse HRQoL. Future studies will examine these factors in larger samples of individuals with FMS or FS to better understand their shared and distinct etiological underpinnings.
RESUMO
Nursing leaders have recognized the need for consistent mechanisms to promote and sustain nursing professionalism. Peer-to-peer feedback and peer review are widely effective for nurse professionalism and self-regulation, patient care outcomes, and retention. Unprofessional behavior has been noted as widespread in health care and the effects on patients, clinicians, and organizations have been well-documented. Approximately 10% of the registered nurses in the United States belong to a collective bargaining unit (CBU) or union. This article will describe how a peer feedback program to address unprofessional behavior was implemented in a Magnet nursing practice with CBU representation.
RESUMO
BACKGROUND: 'Telehealth' online delivery of physiotherapy was the only option during the Covid 19 pandemic in many areas. This was a challenge for physiotherapy training in student clinics where students, clinical educators (CEs) and clients were in three separate locations. The aim of this study was to determine the usability and acceptability of online delivery in a physiotherapy student clinic. METHODS: An observational cross-sectional design was used. Clients (adult clients or carers of paediatric clients), students and CEs participated in telehealth physiotherapy appointments over a Telehealth platform called NeoRehab. The three groups were then invited to complete the Telehealth Usability Questionnaire (TUQ). The 21 item TUQ uses a 7-point Likert scale and covers six constructs (Usefulness, Ease of Use, Interface quality, Interaction quality, Reliability, Satisfaction). RESULTS: Data were analysed from 39 clients, 15 students, and seven CEs. The respective domain scores (SD) for Usefulness [(5.3 (1.5), 5.4 (0.7), 5.1 (0.7)] and Satisfaction [5.1 (1.6), 5.0 (1.0), 5.4 (0.7)] were similarly high across groups, while scores for Reliability [3.7 (1.5), 3.6 (1.0), 3.0 (0.5)] were similarly low across groups. Interface Quality [5.0 (1.5), 4.5 (1.2), 4.1 (0.8)] scores were similarly moderate. Ease of Use [5.6 (1.5), 5.3 (1.0), 4.1 (1.1)] scores were significantly higher in clients than CEs (p = 0.043). Interaction Quality [5.0 (1.4), 3.9 (1.3), 4.2 (0.9)] scores were significantly higher in clients compared with students (p = 0.03). CONCLUSIONS: All groups agreed that the delivery format was useful, easy to use and provided a satisfactory service but was not reliable.

Introduction: Children with developmental coordination disorder (DCD) have difficulties with learning and performing physical tasks. It is well known that task-specific practice is effective in improving motor skills. Additional feedback during practice may function as a quality improvement mechanism and therefore enhance motor skill outcomes. Aims: To investigate the effect of different forms of feedback on motor learning and motor performance in children with DCD. Methods: A systematic review was conducted (registration CRD42020175118) to investigate the effectiveness of different types of feedback, compared to other forms of feedback, or no additional feedback, on motor learning and motor performance outcomes in children with DCD. The search was run across six electronic databases (last search January 2024). Two reviewers independently screened studies for inclusion, assessed the quality of included studies, and extracted relevant data. A narrative synthesis was performed and included studies that assessed motor learning and/or performance outcomes following an intervention that delivered a specific form of feedback in comparison to another form of feedback or no specific feedback. Results: 14 articles from 13 trials were included in this review. Feedback was delivered by providing various forms of feedback, including: knowledge of results, focus of attention and augmented feedback delivered via technology. No significant differences were found between different forms of feedback for motor learning or performance outcomes for children with DCD. Interventions that used technology (with augmented feedback) to deliver the intervention were found to be as effective as traditional therapy. All groups who participated in therapy, regardless of the presence or type of feedback received, improved in overall scores on a motor performance outcome assessment. Conclusion: Despite the clear rationale for using feedback-oriented interventions for children with DCD, there is surprisingly limited and low-quality research. There is no clear evidence that one form of feedback is more effective than another, although it appears that feedback delivered via technology may be as effective as feedback delivered in traditional therapy interventions for children with DCD. Further exploration is required from appropriately powered and well-designed trials.

RESUMO
Background: Children with developmental coordination disorder (DCD) have difficulty learning and performing movements, often requiring increased feedback. Technology may be useful for delivering augmented feedback. Co-design methodology for developing therapeutic interventions has become popular in healthcare, including for technology in rehabilitation. However, there are limited guidelines on how to use co-design methodology in healthcare. Methods: We applied three key principles, (1) Understanding, (2) Exploring, and (3) Materialising, to inform a co-design process. End-user participants included paediatric clinicians, young learners, their caregivers, and the research team, who shared their expertise and lived experience to inform the creation of a novel system. Results: A team of end-users designed and developed an augmented reality intervention prototype for practicing motor skills aimed at children with DCD using a generative co-design process. From understanding the unmet needs, we explored and then materialised a series of games using bespoke technology solutions. Conclusion: The use of a co-design process was beneficial in engaging end-users as the experts of their experience in the creation of a novel augmented reality intervention prototype aimed for children with DCD. The co-design process was successful in facilitating a prototype that meets consumer needs, and ensured all end-user voices were heard.
RESUMO
Background: The resident astrocyte-retinal ganglion cell (RGC) lipoxin circuit is impaired during retinal stress, which includes ocular hypertension-induced neuropathy. Lipoxin B4 produced by homeostatic astrocytes directly acts on RGCs to increase survival and function in ocular hypertension-induced neuropathy. RGC death in the retina and axonal degeneration in the optic nerve are driven by the complex interactions between microglia and macroglia. Whether LXB4 neuroprotective actions include regulation of other cell types in the retina and/or optic nerve is an important knowledge gap. Methods: Cellular targets and signaling of LXB4 in the retina were defined by single-cell RNA sequencing. Retinal neurodegeneration was induced by injecting silicone oil into the anterior chamber of the mouse eyes, which induced sustained and stable ocular hypertension. Morphological characterization of microglia populations in the retina and optic nerve was established by MorphOMICs and pseudotime trajectory analyses. The pathways and mechanisms of action of LXB4 in the optic nerve were investigated using bulk RNA sequencing. Transcriptomics data was validated by qPCR and immunohistochemistry. Differences between experimental groups was assessed by Student's t-test and one-way ANOVA. Results: Single-cell transcriptomics identified microglia as a primary target for LXB4 in the healthy retina. LXB4 downregulated genes that drive microglia environmental sensing and reactivity responses. Analysis of microglial function revealed that ocular hypertension induced distinct, temporally defined, and dynamic phenotypes in the retina and, unexpectedly, in the distal myelinated optic nerve. Microglial expression of CD74, a marker of disease-associated microglia in the brain, was only induced in a unique population of optic nerve microglia, but not in the retina. Genetic deletion of lipoxin formation correlated with the presence of a CD74 optic nerve microglia population in normotensive eyes, while LXB4 treatment during ocular hypertension shifted optic nerve microglia toward a homeostatic morphology and non-reactive state and downregulated the expression of CD74. Furthermore, we identified a correlation between CD74 and phospho-phosphoinositide 3-kinases (p-PI3K) expression levels in the optic nerve, which was reduced by LXB4 treatment. Conclusion: We identified early and dynamic changes in the microglia functional phenotype, reactivity, and induction of a unique CD74 microglia population in the distal optic nerve as key features of ocular hypertension-induced neurodegeneration. Our findings establish microglia regulation as a novel LXB4 target in the retina and optic nerve. LXB4 maintenance of a homeostatic optic nerve microglia phenotype and inhibition of a disease-associated phenotype are potential neuroprotective mechanisms for the resident LXB4 pathway.
RESUMO
In this study the effect of eight DNA topoisomerase inhibitors on the growth Trypanosoma rangeli epimastigotes in cell culture was investigated. Among the eight compounds tested, idarubicin was the only compound that displayed promising trypanocidal activity with a half-maximal growth inhibition (GI50) value in the sub-micromolar range. Fluorescence-activated cell sorting analysis showed a reduction in DNA content in T. rangeli epimastigotes when treated with idarubicin. In contrast to T. rangeli, against Trypanosoma cruzi epimastigotes idarubicin was much less effective exhibiting a GI50 value in the mid-micromolar range. This result indicates that idarubicin displays differential toxic effects in T. rangeli and T. cruzi. Compared with African trypanosomes, it seems that American trypanosomes are generally less susceptible to DNA topoisomerase inhibitors.
