RESUMO
The authors critique the NY Declaration on Animal Consciousness, which does not denounce continued captivity and invasive research in the pursuit of animal consciousness markers. They argue that such research often increases animal suffering by accepting harmful practices. Instead, they propose a nonanthropocentric, ethical framework aligned with the Belmont Report's principle of beneficence, advocating for noninvasive methods in natural habitats. This approach prioritizes animal well-being, recognizing and safeguarding the intrinsic value of all conscious beings.
RESUMO
BACKGROUND: Sanfilippo syndrome (mucopolysaccharidosis type IIIA; MPS IIIA) is a childhood dementia caused by inherited mutations in the sulfamidase gene. At present, there is no treatment and children with classical disease generally die in their late teens. Intravenous or intra-cerebrospinal fluid (CSF) injection of AAV9-gene replacement is being examined in human clinical trials; evaluation of the impact on brain disease is an intense focus; however, MPS IIIA patients also experience profound, progressive photoreceptor loss, leading to night blindness. AIM: To compare the relative efficacy of the two therapeutic approaches on retinal degeneration in MPS IIIA mice. METHODS: Neonatal mice received i.v. or intra-CSF AAV9-sulfamidase or vehicle and after 20 weeks, biochemical and histological evaluation of neuroretina integrity was carried out. RESULTS: Both treatments improved central retinal thickness; however, in peripheral retina, outer nuclear layer thickness and photoreceptor cell length were only significantly improved by i.v. gene replacement. Further, normalization of endo-lysosomal compartment size and microglial morphology was only observed following intravenous gene delivery. CONCLUSIONS: Confirmatory studies are needed in adult mice; however, these data indicate that i.v. AAV9-sulfamidase infusion leads to superior outcomes in neuroretina, and cerebrospinal fluid-delivered AAV9 may need to be supplemented with another therapeutic approach for optimal patient quality of life.

PURPOSE: To evaluate the implementation of MOVIN, a multicomponent mobility intervention, by a nurse-led team and measure the effectiveness on unit-level outcomes. METHOD: A pragmatic quasi-experimental study was conducted on an inpatient adult medical unit. Evaluation was guided by the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework. Interviews with 13 organizational partners were conducted to understand barriers and facilitators to adoption. Thematic analysis was used to analyze the data. Quantitative data to determine effectiveness on distance of patient ambulation and percent of patients ambulated by nursing staff were analyzed using an interrupted time series. RESULTS: A significant increase in total weekly distances for patient ambulation and percent of patients ambulated by nursing staff occurred between preintervention, intervention, and postintervention periods. Themes for adoption included: Value, Immediate Feedback, Inclusive Implementation, Resource Needs, and Lack of Organizational Evidence. The nurse-led team demonstrated high fidelity to maintaining the core components of MOVIN. CONCLUSION: A nurse-led team can successfully launch a multicomponent mobility intervention and sustain impact. RE-AIM supported assessments of key partners at multiple organizational levels, capturing critical unit level outcomes. Multiple methods for data collection and analysis yielded rich results to inform future dissemination of MOVIN. [Research in Gerontological Nursing, 17(4), 189-201.].

We developed an ankle-worn gait monitoring system for tracking gait parameters, including length, width, and height. The system utilizes ankle bracelets equipped with wide-angle infrared (IR) stereo cameras tasked with monitoring a marker on the opposing ankle. A computer vision algorithm we have also developed processes the imaged marker positions to estimate the length, width, and height of the person's gait. Through testing on multiple participants, the prototype of the proposed gait monitoring system exhibited notable performance, achieving an average accuracy of 96.52%, 94.46%, and 95.29% for gait length, width, and height measurements, respectively, despite distorted wide-angle images. The OptiGait system offers a cost-effective and user-friendly alternative compared to existing gait parameter sensing systems, delivering comparable accuracy in measuring gait length and width. Notably, the system demonstrates a novel capability in measuring gait height, a feature not previously reported in the literature.
RESUMO
Hampering assessment of treatment outcomes in gene therapy and other clinical trials in patients with childhood dementia is the lack of an objective, non-invasive measure of neurodegeneration. Optical coherence tomography (OCT) is a widely available, rapid, non-invasive, and quantitative method for examining the integrity of the neuroretina. Profound brain and retinal dysfunction occur in patients and animal models of childhood dementia, including Sanfilippo syndrome and we recently revealed a correlation between the age of onset and rate of progression of retinal and brain degeneration in sulfamidase-deficient Sanfilippo mice. The aim of the current study was to use OCT to visualise the discrete changes in retinal structure that occur during disease progression. A progressive decline in retinal thickness was readily observable in Sanfilippo mice using OCT, with differences seen in affected animals from 10-weeks of age. OCT applied to i.v. AAV9-sulfamidase-treated Sanfilippo mice enabled visualisation of improved retinal anatomy in living animals, an outcome confirmed via histology. Importantly, brain disease lesions were also ameliorated in treated Sanfilippo mice. The findings highlight the sensitivity, ease of repetitive use and quantitative capacity of OCT for detection of discrete changes in retinal structure and their prevention with a therapeutic. Combined with the knowledge that retinal and brain degeneration are correlated in Sanfilippo syndrome, OCT provides a window to the brain in this and potentially other childhood dementias.

OBJECTIVE: Filipin complex is an autooxidation-prone fluorescent histochemical stain used in the diagnosis of Niemann-Pick Disease Type C (NP-C), a neurodegenerative lysosomal storage disorder. It is also widely used by researchers examining the distribution and accumulation of unesterified cholesterol in cell and animal models of neurodegenerative diseases including NP-C and Sanfilippo syndrome (mucopolysaccharidosis IIIA; MPS IIIA). Recently, it has been suggested to be useful in studying Alzheimer's and Huntington's disease. Given filipin's susceptibility to photobleaching, we sought to establish a quantitative biochemical method for free cholesterol measurement. METHODS: Brain tissue from mice with MPS IIIA was stained with filipin. Total and free cholesterol in brain homogenates was measured using a commercially available kit and a quantitative LC-MS/MS assay was developed. Gangliosides GM1, GM2 and GM3 were also quantified using LC-MS/MS. RESULTS: As anticipated, the MPS IIIA mouse brain displayed large numbers of filipin-positive intra-cytoplasmic inclusions, presumptively endo-lysosomes. Challenging the prevailing dogma, however, we found no difference in the amount of free cholesterol in MPS IIIA mouse brain homogenates cf. control tissue, using either the fluorometric kit or LC-MS/MS assay. Filipin has previously been reported to bind to GM1 ganglioside, however, this lipid does not accumulate in MPS IIIA cells/tissues. Using a fluorometric assay, we demonstrate for the first time that filipin cross-reacts with both GM2 and GM3 gangliosides, explaining the filipin-reactive inclusions observed in MPS IIIA brain cells. CONCLUSION: Filipin is not specific for free cholesterol, and positive staining in any setting should be interpreted with caution.

RESUMO
ABSTRACT: BACKGROUND: Older people with debilitating degenerative spine disease may benefit from surgery. However, recovery is described as a circuitous process. In general, they describe feeling powerless and receiving depersonalized care during hospitalization. Institution of hospital no-visitor policies to reduce COVID-19 spread may have caused additional negative consequences. The purpose of this secondary analysis was to understand experiences of older people who underwent spine surgery during early COVID-19. METHODS: Grounded theory guided this study of people 65 years or older undergoing elective spine surgery. Fourteen individuals were recruited for 2 in-depth interviews at 2 time points: T1 during hospitalization and T2, 1 to 3 months post discharge. All participants were affected by pandemic-imposed restrictions with 4 interviews at T1 with no visitors, 10 with a 1-visitor policy, and 6 interviews at T2 rehabilitation setting with no visitors. Discriminate sampling of data in which participants described their experiences with COVID-19 visitor restrictions was used. Open and axial coding (consistent with grounded theory) was used for data analysis. RESULTS: Three categories, worry and waiting , being alone , and being isolated , emerged from the data. Participants had delays ( waiting ) in getting their surgery scheduled, which produced worry that they would lose more function, become permanently disabled, have increased pain, and experience more complications such as falls. Participants described being alone during their hospital and rehabilitation recovery, without physical or emotional support from family and limited nursing staff contact. Being isolated often occurred from institution policy, restricting participants to their rooms leading to boredom and, for some, panic. CONCLUSIONS: Restricted access to family after spine surgery and during recovery resulted in emotional and physical burden for participants. Our findings support neuroscience nurses advocating for family/care partner integration into patient care delivery and investigation into the effect of system-level policies on patient care and outcomes.

RESUMO
AIMS: To explore how primary care registered nurses (PCRNs) describe their professional identity, their perception of their practice, and the support they need to effectively perform the responsibilities of their role. DESIGN: A qualitative descriptive design using inductive content analysis. METHODS: Semi-structured interviews were conducted with registered nurses (n = 14) working in primary care settings in the United States between June 2018 and December 2020. Inductive content analysis was used and comprised three phases: preparation, organizing, and reporting. COREQ reporting guidelines were used. RESULTS: Three categories were discovered related to PCRN identity and practice: Wearing Multiple Hats, Practicing Within Bounds and Change is a Part of Practice. There were also three categories for support needed: Entering In, Ongoing Support and Making it a Better Place. Within each category, subcategories were identified. CONCLUSION: Primary care registered nurses have a unique professional identity and practice. When entering the setting, nurses must acquire the skills and knowledge to ask the right questions and navigate the system to meet the diverse and complex needs of their patients. PCRNs recognize change is a part of practice and have ideas and visions for what the role of PCRNs could be. IMPLICATIONS FOR PROFESSION: Recognizing the unique identity and practice of PCRNs is necessary to create an environment that leverages their skills and knowledge. IMPACT: We identified key elements of PCRN identity and practice and the support necessary to meet their needs. Healthcare organizations must ensure nurses new to the practice setting receive training and support for their unique and essential role. Additionally, leaders must partner with nurses to enhance nursing practice and achieve optimal patient outcomes. REPORTING METHOD: Adherence to COREQ guidelines were maintained. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

BACKGROUND: Heuristic evaluations, while commonly used, may inadequately capture the severity of identified usability issues. In the domain of health care, usability issues can pose different levels of risk to patients. Incorporating diverse expertise (eg, clinical and patient) in the heuristic evaluation process can help assess and address potential negative impacts on patient safety that may otherwise go unnoticed. One document that should be highly usable for patients-with the potential to prevent adverse outcomes-is the after visit summary (AVS). The AVS is the document given to a patient upon discharge from the emergency department (ED), which contains instructions on how to manage symptoms, medications, and follow-up care. OBJECTIVE: This study aims to assess a multistage method for integrating diverse expertise (ie, clinical, an older adult care partner, and health IT) with human factors engineering (HFE) expertise in the usability evaluation of the patient-facing ED AVS. METHODS: We conducted a three-staged heuristic evaluation of an ED AVS using heuristics developed for use in evaluating patient-facing documentation. In stage 1, HFE experts reviewed the AVS to identify usability issues. In stage 2, 6 experts of varying expertise (ie, emergency medicine physicians, ED nurses, geriatricians, transitional care nurses, and an older adult care partner) rated each previously identified usability issue on its potential impact on patient comprehension and patient safety. Finally, in stage 3, an IT expert reviewed each usability issue to identify the likelihood of successfully addressing the issue. RESULTS: In stage 1, we identified 60 usability issues that violated a total of 108 heuristics. In stage 2, 18 additional usability issues that violated 27 heuristics were identified by the study experts. Impact ratings ranged from all experts rating the issue as "no impact" to 5 out of 6 experts rating the issue as having a "large negative impact." On average, the older adult care partner representative rated usability issues as being more significant more of the time. In stage 3, 31 usability issues were rated by an IT professional as "impossible to address," 21 as "maybe," and 24 as "can be addressed." CONCLUSIONS: Integrating diverse expertise when evaluating usability is important when patient safety is at stake. The non-HFE experts, included in stage 2 of our evaluation, identified 23% (18/78) of all the usability issues and, depending on their expertise, rated those issues as having differing impacts on patient comprehension and safety. Our findings suggest that, to conduct a comprehensive heuristic evaluation, expertise from all the contexts in which the AVS is used must be considered. Combining those findings with ratings from an IT expert, usability issues can be strategically addressed through redesign. Thus, a 3-staged heuristic evaluation method offers a framework for integrating context-specific expertise efficiently, while providing practical insights to guide human-centered design.
RESUMO
BACKGROUND AND OBJECTIVES: Globally, older adults are undergoing spine surgery for degenerative spine disease at exponential rates. However, little is known about their experiences of living with and having surgery for this debilitating condition. This study investigated older adults' understanding and experiences of living with and having surgery for degenerative spine disease. RESEARCH DESIGN AND METHODS: Qualitative methods, grounded theory, guided the study. Fourteen older adults (≥65 years) were recruited for in-depth interviews at 2 time-points: T1 during hospitalization and T2, 1-3-months postdischarge. A total of 28 interviews were conducted. Consistent with grounded theory, purposive, and theoretical sampling were used. Data analysis included open, axial, and selective coding. RESULTS: A conceptual model was developed illustrating the process older adults with degenerative spine disease experience, trying to get their life back. Three key categories were identified (1) Losing Me, (2) Fixing Me, and (3) Recovering Me. Losing Me was described as a prolonged process of losing functional independence and the ability to socialize. Fixing Me consisted of preparing for surgery and recovery. Recovering Me involved monitoring progression and reclaiming their personhood. Conditions, including setbacks and delays, slowed their trajectory. Throughout, participants continually adjusted expectations. DISCUSSION AND IMPLICATIONS: The conceptual model, based on real patient experiences, details how older adults living with and having surgery for degenerative spine disease engage in recovering who they were prior to the onset of symptoms. Our findings provide a framework for understanding a complex, protracted trajectory that involves transitions from health to illness working toward health again.

AIM: The aim of this study is to assess effect of hospital walking programs on outcomes for older inpatients and to characterize hospital walking dose reported across studies. DESIGN: A systematic review and meta-analysis examining impact of hospital walking and/or reported walking dose among medical-surgical inpatients. For inclusion, studies were observational or experimental, published in English, enrolled inpatients aged ≥ 65 yrs hospitalized for medical or surgical reasons. METHODS: Searches of PubMed, CINAHL, Embase, Scopus, NICHSR, OneSearch, ClinicalTrials.gov, and PsycINFO were completed in December 2020. Two reviewers screened sources, extracted data, and performed quality bias appraisal. RESULTS: Hospital walking dose was reported in 6 studies and commonly as steps/24 hr. Length of stay (LOS) was a common outcome reported. Difference in combined mean LOS between walking and control groups was -5.89 days. Heterogeneity across studies was considerable (I2 = 96%) suggesting poor precision of estimates. Additional, high-quality trials examining hospital walking and patient outcomes of older patients is needed.

BACKGROUND AND OBJECTIVES: Physical literacy refers to a holistic view of physical activity (PA), which proposes that a person needs to be motivationally, physically, strategically, mentally, socially, and knowledgeably prepared to be and stay physically active. It has been recently introduced in the field of older adults' PA. Our study sought to develop the Perceived Physical Literacy for Chinese Elderly Questionnaire (PPLCEQ) and evaluate its psychometric properties. RESEARCH DESIGN AND METHODS: We conducted qualitative interviews and literature reviews to develop the item pool. Expert panel review and cognitive interviewing were used to evaluate the questionnaire's content validity. A convenience sample of 388 Chinese older adults was recruited to assess the questionnaire's validity and reliability. RESULTS: The developed PPLCEQ includes 47 items. Consistent with the conceptual definition of physical literacy, exploratory factor analysis showed that the PPLCEQ is composed of 6 subscales. Participants' PPLCEQ scores were moderately correlated to their leisure-time PA (r = 0.38, p < .001), PA maintenance (r = 0.44, ps < .001), and perceived competence for exercising regularly scores (r = 0.58, p < .001). Moreover, the Cronbach's alpha and the test-retest reliability of the questionnaire were 0.88 and 0.70, respectively. DISCUSSION AND IMPLICATIONS: Psychometric assessment results suggest that the PPLCEQ is a reliable and valid tool that can be used in future studies investigating Chinese older adults' perceived physical literacy.

RESUMO
BACKGROUND: Patient mobility is an evidenced-based physical activity intervention initiated during intensive care unit (ICU) admission and continued throughout hospitalization to maintain functional status, yet mobility is a complex intervention and not consistently implemented. Cognitive work analysis (CWA) is a useful human factors framework for understanding complex systems and can inform future technology design to optimize outcomes. OBJECTIVE: The aim of this study is to understand the complexity and constraints of the ICU work environment as it relates to nurses carrying out patient mobility interventions, using CWA. METHODS: We conducted a work domain analysis and completed an abstraction hierarchy using the CWA framework. Data from documents, observation (32 hours), and interviews with nurses (N=20) from 2 hospitals were used to construct the abstraction hierarchy. RESULTS: Nurses seek information from a variety of sources and integrate patient and unit information to inform decision-making. The completed abstraction hierarchy depicts multiple high-level priorities that nurses balance, specifically, providing quality, safe care to patients while helping to manage unit-level throughput needs. Connections between levels on the abstraction hierarchy describe how and why nurses seek patient and hospital unit information to inform mobility decision-making. The analysis identifies several opportunities for technology design to support nurse decision-making about patient mobility. CONCLUSIONS: Future interventions need to consider the complexity of the ICU environment and types of information nurses need to make decisions about patient mobility. Considerations for future system redesign include developing and testing clinical decision support tools that integrate critical patient and unit-level information to support nurses in making patient mobility decisions.
RESUMO
OBJECTIVE: To describe older adult patients' and care partners' knowledge broker roles during emergency department (ED) visits. BACKGROUND: Older adult patients are vulnerable to communication and coordination challenges during an ED visit, which can be exacerbated by the time and resource constrained ED environment. Yet, as a constant throughout the patient journey, patients and care partners can act as an information conduit, or knowledge broker, between fragmented care systems to attain high-quality, safe care. METHODS: Participants included 14 older adult patients (≥ 65 years old) and their care partners (e.g., spouse, adult child) who presented to the ED after having experienced a fall. Human factors researchers collected observation data from patients, care partners and clinician interactions during the patient's ED visit. We used an inductive content analysis to determine the role of patients and care partners as knowledge brokers. RESULTS: We found that patients and care partners act as knowledge brokers by providing information about diagnostic testing, medications, the patient's health history, and care accommodations at the disposition location. Patients and care partners filled the role of knowledge broker proactively (i.e. offer information) and reactively (i.e. are asked to provide information by clinicians or staff), within-ED work system and across work systems (e.g., between the ED and hospital), and in anticipation of future knowledge brokering. CONCLUSION: Patients and care partners, acting as knowledge brokers, often fill gaps in communication and participate in care coordination that assists in mitigating health care fragmentation.
