Prospective fecal microbiomic biomarkers for chronic wasting disease.

Chronic wasting disease (CWD) is a naturally occurring prion disease in cervids that has been rapidly proliferating in the United States. Here, we investigated a potential link between CWD infection and gut microbiome by analyzing 50 fecal samples obtained from CWD-positive animals of different sexes from various regions in the USA compared to 50 CWD-negative controls using high throughput sequencing of the 16S ribosomal RNA and targeted metabolomics. Our analysis reveals promising trends in the gut microbiota that could potentially be CWD-dependent, including several bacterial taxa at each rank level, as well as taxa pairs, that can differentiate between CWD-negative and CWD-positive deer. Through machine-learning, these taxa and taxa pairs at each rank level could facilitate identification of around 70% of both the CWD-negative and the CWD-positive samples. Our results provide a potential tool for diagnostics and surveillance of CWD in the wild, as well as conceptual advances in our understanding of the disease.IMPORTANCEThis is a comprehensive study that tests the connection between the composition of the gut microbiome in deer in response to chronic wasting disease (CWD). We analyzed 50 fecal samples obtained from CWD-positive animals compared to 50 CWD-negative controls to identify CWD-dependent changes in the gut microbiome, matched with the analysis of fecal metabolites. Our results show promising trends suggesting that fecal microbial composition can directly correspond to CWD disease status. These results point to the microbial composition of the feces as a potential tool for diagnostics and surveillance of CWD in the wild, including non-invasive CWD detection in asymptomatic deer and deer habitats, and enable conceptual advances in our understanding of the disease.

Metagenomics for Pathogen Detection During a Mass Mortality Event in Songbirds.

Mass mortality events in wildlife can be indications of an emerging infectious disease. During the spring and summer of 2021, hundreds of dead passerines were reported across the eastern US. Birds exhibited a range of clinical signs including swollen conjunctiva, ocular discharge, ataxia, and nystagmus. As part of the diagnostic investigation, high-throughput metagenomic next-generation sequencing was performed across three molecular laboratories on samples from affected birds. Many potentially pathogenic microbes were detected, with bacteria forming the largest proportion; however, no singular agent was consistently identified, with many of the detected microbes also found in unaffected (control) birds and thus considered to be subclinical infections. Congruent results across laboratories have helped drive further investigation into alternative causes, including environmental contaminants and nutritional deficiencies. This work highlights the utility of metagenomic approaches in investigations of emerging diseases and provides a framework for future wildlife mortality events.

'I just need to know what they are and if you can help me': Medicalization and the search for legitimacy in people diagnosed with non-epileptic attack disorder.

This paper focuses on the struggles for legitimacy expressed by people with non-epileptic attack disorder (NEAD), one of the most common manifestations of functional neurological disorder presenting to emergency and secondary care services. Nonepileptic attacks are episodes of altered experience, awareness, and reduced self-control that superficially resemble epileptic seizures or other paroxysmal disorders but are not associated with physiological abnormalities sufficient to explain the semiological features. "Organic" or medicalized explanations are frequently sought by patients as the only legitimate explanation for symptoms, and consequently, a diagnosis of NEAD is often contested. Drawing on narrative interviews with patients from a small exploratory study and using a sociological perspective, we propose that a psychological account of NEAD does not provide a sufficiently legitimate path into a socially sanctioned sick role. This is a reflection of the dominance of biomedicine and the associated processes of medicalization. These processes are, we argue, the sole route to achieving legitimacy. The stress-based or psychologically oriented explanations offered to patients in contemporary medical models of the etiology of NEAD engender an uncertain identity and social position and fail to provide many patients with an account of the nature or origin of their symptoms that they find satisfactory or convincing. These struggles for legitimacy (shared by others with functional or somatoform conditions) are sharpened by key features of the contemporary healthcare landscape, such as the increasing framing of health through a lens of 'responsibilization'.

An Integrative Review of the Use of the Individual and Family Self-Management Theory in Research.

The extent of the application of the Individual and Family Self-Management Theory (IFSMT) in research has yet to be determined. The purpose of this analysis was to review the use of the IFSMT in published research and evaluate posited constructs and relationships. Dimensions and categories of the IFSMT and the interrelationships were generally supported in the 77 articles reviewed. A majority focused on self-management of chronic conditions in the adult population. More research on the strength, direction, and interaction of relationships is needed. Defining and exploring social constructs, including race, ethnicity, and gender, should be prioritized in future IFSMT research.

Unexpected lucidity in dementia: application of qualitative methods to develop an informant-reported lucidity measure.

OBJECTIVES: Unexpected lucidity is a phenomenon of scientific, clinical, and psychological relevance to health professionals, to those who experience it, and their relatives. This paper describes qualitative methods used to develop an informant-based measure of lucidity episodes. METHODS: The approach was refinement of the operationalization of the construct; review of seminal items, modification, and purification; and confirmation of the feasibility of reporting methodology. Modified focus groups were conducted with 20 staff and 10 family members using a web-based survey. Themes included reaction when hearing the term; words that come to mind; description of and first reaction to referenced or observed 'lucidity' events. Semi-structured cognitive interviews were conducted with 10 health professionals working with older adults with cognitive impairment. Data were extracted from Qualtrics or Microsoft 365 Word® for analysis using NVivo. RESULTS: Conceptual issues, as well as issues regarding comprehension, interpretation, clarity, semantics, and standardization of definitions derived from an external advisory board, focus groups and cognitive interviews informed items' modification, and resulted in the final lucidity measure. CONCLUSIONS: An obstacle to understanding the mechanisms and estimating the prevalence of lucid events among individuals with dementia and other neurological conditions is the scarcity of reliable and valid measures. The substantive and varied data gathered from multiple methods including the collaborative work of an External Advisory Board, modified focus groups with staff and family caregivers, and structured cognitive interviews with health professionals were central in creating the revised version of the lucidity measure.

Canine detection of chronic wasting disease (CWD) in laboratory and field settings.

Chronic wasting disease (CWD) is a fatal transmissible spongiform encephalopathy that affects both free-ranging and farmed cervid species, including mule deer, white-tailed deer, and elk (Odocoileus hemionus, Odocoileus virginianus, and Cervus canadensis). Due to the long incubation period and variability of clinical signs, CWD can expand and spread to new areas before they reach diagnostically detectable levels. Antemortem testing methods currently available can be difficult to obtain and to be applied to the large numbers required for adequate surveillance. However, key volatile biomarkers could be harnessed for non-invasive antemortem surveillance. Detection dogs are the most effective tool currently available for volatile detection; dogs can effectively complete wildlife surveys at rates surpassing that of humans. This study is the first to demonstrate that trained detection dogs can be used as an antemortem test for CWD. First, we trained three dogs to differentiate between CWD-positive and CWD-negative white-tailed deer faeces in a laboratory setting. Dogs spent significantly more time at the positive sample than the negative samples, suggesting that they differentiated between the positive and negative volatile signatures. We then trained the same dogs to search for CWD-positive faecal samples in a more naturalistic field setting. In the field, dogs found 8/11 CWD-positive samples and had an average false detection rate of 13%. These results suggest that dogs can be trained to differentiate CWD-positive faeces from CWD-negative faeces in both laboratory and field settings. Future studies will compare canine accuracy to other antemortem methods, as well as improved canine training methods.

Ageism in the Nursing Care of Older Adults: A Concept Analysis.

Despite the high prevalence of ageism worldwide, it is still underestimated and unrecognized by many nurses. Concept clarification is required to delineate the meaning of the word "ageism" in nursing. The purpose of this concept analysis is to clearly define the concept of ageism relative to nursing discipline using the Walker and Avant method. Defining the concept of ageism will provide nurses with a better understanding of its causes and consequences. It will aid policy makers in developing policies and interventions to help decrease ageism in health care environments.

Reports About Paradoxical Lucidity from Health Care Professionals: A Pilot Study.

Although clinicians caring for persons at the end of life recognize the phenomenon of paradoxical/terminal lucidity, systematic evidence is scant. The current pilot study aimed to develop a structured interview instrument for health care professionals to report lucidity. A questionnaire measuring lucidity length, degree, content, coinciding circumstances, and time from episode to death was expanded to include time of day, expressive and receptive communication, and speech during the month prior to and during the event. Thirty-three interviews were conducted; 73% of participants reported ever witnessing paradoxical lucidity. Among 29 events reported, 31% lasted several days, 20.7% lasted 1 day, and 24.1% lasted <1 day. In 78.6% of events, the person engaged in unexpected activity; 22.2% died within 3 days, and 14.8% died within 3 months of the event. The phenomenological complexity of lucidity presents challenges to eliciting reports in a systematic fashion; however, staff respondents were able to report lucidity events and detailed descriptions of person-specific characteristics.

SURVEILLANCE OF BATS IN THE UNITED STATES FOR SARS-COV-2 AND OTHER CORONAVIRUSES.

Bat coronaviruses (CoVs) are extremely prevalent throughout the globe and exhibit a wide range of genetic diversity. Currently, little is known about the susceptibility of New World bats to severe acute respiratory syndrome-2 (SARS-CoV-2), the causative agent of COVID-19. Also, there is limited information about the genetic diversity of other CoVs in the New World bats. The determination of genetic diversity of bat CoVs through continuous surveillance is essential to predict and mitigate the emergence of new CoVs and their impacts on the health of both humans and animals. In this study, 491 guano specimens collected from New World bats and 37 specimens collected from Old World bats during July 2020 to July 2021 were tested for SARS-COV-2 and other CoVs using a real-time reverse transcriptase-polymerase chain reaction (RT-PCR) panel and pan-coronavirus PCR that target a highly conserved region of CoVs. No evidence of SARS-CoV-2 was found in the tested specimens. An alpha CoV was detected in a single specimen from a big brown bat (Eptesicus fuscus). This information was used by wildlife agencies and rehabilitation facilities to permit the release of bats during the pandemic while mitigating the risk of spreading SARS-CoV-2 among North American bats and other wild animal populations.

Clinical Nurse Specialist Transition to Practice.

PURPOSE: A quality improvement/evidence-based practice project identified the critical components of clinical nurse specialist (CNS) transition-to-practice (TTP) needs based on the experiences and perceptions of entry-level CNSs (n = 4), experienced CNSs (n = 7), and directors of nursing (n = 6) employed in a tertiary healthcare center. Structured 60- to 90-minute face-to-face discussions were conducted. DESCRIPTION: As knowledge workers, CNSs are critical to investigating, solving, and transforming some of the most challenging current and future healthcare problems. Lack of standardized CNS TTP may result in variable levels of practice, knowledge, skill attainment, and ability to attain interdisciplinary practice competencies. OUTCOMES: Findings included identification of entry-level CNS TTP key components: 16 categories with 8 critical categories identified as imminent needs. Challenges identified included stakeholders' lack of knowledge/understanding of the CNS role and scope; enormous TTP expectations of entry-level CNSs; transdisciplinary relationships and collaboration; leadership culture and collaboration; organizational culture; deliberate practice; and lack of support, resources, and basic needs. CONCLUSION: Critical components for advanced deliberate practice within a CNS TTP program include an organizational culture and subculture that understands and values the CNS, along with tiered sustainable support from preceptors, mentors, and support CNSs across the setting and system.

Primary Caregivers Caring for a Child at End of Life in Saudi Arabia.

Background: Caring for children at end of life (EOL) can be devastating for primary caregivers who are responsible for the physical, social, and emotional needs of their dying child. Limited information was found on resources in Saudi Arabia to manage the impact on primary caregivers from caring for a child receiving end of life care (EOLC). Purpose: The purpose of this study was to explore the experiences of primary caregivers caring for a child receiving EOLC within the Saudi Arabian health care system. Methods: A descriptive phenomenological study was conducted, and 24 female primary caregivers were interviewed individually. Participants were recruited from three hospitals and the surrounding community in Jeddah, Saudi Arabia. The data were collected over a period of seven weeks between August and September of 2019. Individual in-depth interviews were conducted using an 11-item investigator-developed interview guide derived from the literature on EOL. Thematic analysis was completed using transcripts from all interviews. Results: The findings suggest that primary caregivers caring for a child receiving EOLC were impacted psychologically, physically, socially, and financially. Primary caregivers expressed their heartbreak, lack of sleep, isolation, and financial challenges while caring for their child at EOL. Conclusions: Similar to what has been reported in the literature, primary caregivers caring for a child at EOL experience biopsychosocial and financial challenges. In addition, this study has implications for nursing education, practice, policy, and research regarding EOLC. Also, the findings can guide future research on EOL in Saudi Arabia and worldwide.

Multiple Introductions of SARS-CoV-2 Alpha and Delta Variants into White-Tailed Deer in Pennsylvania.

The SARS-CoV-2 pandemic began by viral spillover from animals to humans; today multiple animal species are known to be susceptible to infection. White-tailed deer, Odocoileus virginianus, are infected in North America at substantial levels, and genomic data suggests that a variant in deer may have spilled back to humans. Here, we characterize SARS-CoV-2 in deer from Pennsylvania (PA) sampled during fall and winter 2021. Of 123 nasal swab samples analyzed by RT-qPCR, 20 (16.3%) were positive for SARS-CoV-2. Seven whole genome sequences were obtained, together with six more partial spike gene sequences. These annotated as alpha and delta variants, the first reported observations of these lineages in deer, documenting multiple new jumps from humans to deer. The alpha lineage persisted in deer after its displacement by delta in humans, and deer-derived alpha variants diverged significantly from those in humans, consistent with a distinctive evolutionary trajectory in deer. IMPORTANCE Coronaviruses have been documented to replicate in numerous species of vertebrates, and multiple spillovers of coronaviruses from animals into humans have founded human epidemics. The COVID-19 epidemic likely derived from a spillover of SARS-CoV-2 from bats into humans, possibly via an intermediate host. There are now several examples of SARS-CoV-2 jumping from humans into other mammals, including mink and deer, creating the potential for new animal reservoirs from which spillback into humans could occur. For this reason, data on formation of new animal reservoirs is of great importance for understanding possible sources of future infection. Here, we identify extensive infection in white-tailed deer in Pennsylvania, including what appear to be multiple independent transmissions. Data further suggests possible transmission among deer. These data thus help identify a potential new animal reservoir and provide background information relevant to its management.

The Effect of Racism and Discrimination on the Health of Milwaukee's African American Population.

BACKGROUND: This scoping review focuses on the intersections of racism, health, and health care, as well as interventions for the African American population in Milwaukee, Wisconsin-one of the most hypersegregated regions in the country. We investigate what existing research provides about the impact of segregation and racism on health and consider how community setting informs health interventions, practice, and policy. METHODS: We analyzed studies that address racism and health in Milwaukee to assess the state of the science in this area. We searched databases using the terms "African American," "racism," "segregation," and "health." A total of 296 studies resulted, and 54 met the inclusion criteria. RESULTS: Racism is a known determinant of health. However, a lack of research investigating the impact of racism on health in Milwaukee County leaves a knowledge gap necessary for improving health among African American residents. The adverse effects of racism on health are compounded by the social, economic, and policy context of geographic and social segregation that limit access to care and resilience. Themes identified in the review include measures of physical and mental health, community factors related to health (eg, housing, environmental contamination, economic and social exclusion), intervention strategies, and theoretical gaps. DISCUSSION: Professionals must work across disciplines and social sectors to address the effects of racism on the physical and mental health of African American individuals in urban metropolitan environments. Health research and medical interventions in hypersegregated communities must center structural racism in their analysis.

Effect of Water Depth on Limb and Back Kinematics in Horses Walking on a Water Treadmill.

Water treadmill (WT) exercise is frequently used for training/rehabilitation of horses. There is limited study into the effect of water depth on limb/back kinematics warranting investigation. The objective was to determine the effect of walking in different water depths, at the same speed, on limb/back kinematics measured simultaneously in a group of horses. Six horses (age:15 ± 6.5 years) completed a standardized WT exercise session (19 minutes duration; speed:1.6 m/s; water depths: 0.0/7.5/21.0/32.0/47.0 cm). Ten waterproof light-emitting-diode tea-light-markers and reflective-spheres were affixed to the skin at predetermined locations; inertial-measurement-units were fixed to the poll/withers/left and right tubera coxae (TC)/sacrum to determine range-of-motion (ROM) changes of these locations. Univariable-mixed-effects-linear-regression-analyses were carried out, with a significance value of P ≤ .05. At maximum carpal/tarsal flexion during swing, regression analyses showed a clear and consistent nonlinear increase in carpal and tarsal flexion at increasing water depths (P < 0.0001 for both variables). As water depth increased there was a significant increase in thoracic spine flexion-extension ROM (P < 0.0001 at all thoracic sites) and increased dorsoventral and mediolateral ROM of the sacrum/left and right TC (P < 0.001 for all variables) as water depth increased. Results suggest that horses responded to an increase in water depth until a threshold depth was reached when the biomechanical response levelled off, and there was increased pelvic roll. In conclusion, changes in limb kinematics brought about by relatively modest increases in water depth at walking speed of 1.6 m/s are sufficient to induce significant changes in back/pelvic movement highlighting key issues with relevance for WT program design.

Bat Red Blood Cells Express Nucleic Acid-Sensing Receptors and Bind RNA and DNA.

RBCs demonstrate immunomodulatory capabilities through the expression of nucleic acid sensors. However, little is known about bat RBCs, and no studies have examined the immune function of bat erythrocytes. In this study, we show that bat RBCs express the nucleic acid-sensing TLRs TLR7 and TLR9 and bind the nucleic acid ligands, ssRNA, and CpG DNA. Collectively, these data suggest that, like human RBCs, bat erythrocytes possess immune function and may be reservoirs for nucleic acids. These findings provide unique insight into bat immunity and may uncover potential mechanisms by which virulent pathogens of humans are concealed in bats.

Objective Physical Activity Levels, Sedentary Time, and Muscle Mass, Strength, and Function: Impact on Physical and Mental Health-Related Quality of Life in Older Adults.

Limited physical activity, sedentary behavior, and reduction in muscle mass, strength, and function are accompanied by negative outcomes. The relationship between these factors and physical and mental health-related quality of life (HRQoL) has yet to be elucidated in continuing care retirement community (CCRC) residents. The current study investigated the relationships among physical activity, sedentary behavior, and muscle mass, strength, and function to physical and mental HRQoL. A sample of 105 CCRC residents participated in this cross-sectional correlational study. Findings demonstrated that low physical activity and muscle function were significantly associated with low physical HRQoL and explained 38% of the variance in physical HRQoL. Handgrip strength was significantly associated with low mental HRQoL and explained 8% of the variance in mental HRQoL. Older adults living in CCRCs may benefit from interventions targeting physical activity and the distinct muscle components of sarcopenia that have the potential to improve physical and mental HRQoL.

A Quality Initiative Incorporating Tablet Technology to Facilitate Nonpharmacologic Pain Intervention Use in the Hospital.

BACKGROUND: The opioid crisis has changed the culture and expectations of pain management, elevating the importance of nonpharmacologic pain interventions (NPIs) into multimodal pain management programs. Little is known about use of NPIs in hospitalized patients. AIMS: This quality improvement project aimed to increase awareness and use of NPIs by engaging patients and nurses on one medical unit using tablet technology. METHODS: Pre- and post intervention data were collected using surveys of nurse and nursing assistant perceptions of NPIs and by assessing pain management experiences of acute care patients using the American Pain Society-Pain Outcomes Questionnaire-Revised. Interventions included staff education, integration of an NPI menu and tools onto bedside tablets, and a Comfort Card communication tool. SETTINGS: This Quality Improvement project was conducted on an 18-bed adult medical unit at a Midwestern academic medical center. PARTICIPANTS/SUBJECTS: Subjects included RN and Certified Nursing Assistants from one medical unit. Patient perspectives were obtained from a baseline cohort of 30 hospitalized medical patients and compared to an intervention group of 15 medical patients. Patient inclusion criteria included adults ages 18 and older, hospitalized ≤72 hours, who verbalized a willingness to participate. DESIGN: The 8-week project included nurse and nursing assistant pre-/post-intervention perception surveys and an educational module about NPIs. Pain management experiences and NPI use were assessed post-tablet intervention using the American Pain Society-Pain Outcomes Questionnaire-Revised (APS-POQ-R). Additionally, staff education, integration of an NPI menu and tools onto bedside tablets, and a Comfort Card communication tool were planned interventions. RESULTS: Nursing staff believe NPIs are beneficial, safe, and evidence-based; however, limited resources, time constraints, and lack of provider support are perceived as barriers. Staff and volunteers provided 80 comfort items to 38 patients during the project. Half of baseline patients (n = 30) and intervention (n = 15) groups reported not receiving information about pain treatment options. Many patients in both groups denied using "non medicine methods," but further assessment revealed that 90% of the baseline group and 87% of the intervention group had used an NPI. CONCLUSIONS: Results suggest that patients and nurses may benefit from education about using NPIs in acute care. Nurses have a critical role influencing positive pain-related outcomes, and tablet technology can enhance patient use of NPIs during hospitalization.

Psychosocial modification of general self-efficacy in older adults: A restricted review.

OBJECTIVES: In recent years, the concept of general self-efficacy has increased in popularity. General self-efficacy is positively associated with quality of life and has the potential to act as a psychological buffer against adverse events and circumstances. However, due to the long-term influences that are said to shape general self-efficacy beliefs, they may be resistant to intervention, particularly within the older population. This restricted review aimed to explore whether psychosocial interventions could improve the general self-efficacy of older adults. Aspects of intervention design associated with improvements were also investigated. METHODS: A restricted review was undertaken. This included a keyword search of four major health databases (PubMed, CINAHL, PsycINFO and AgeLine). Search terms focused on general self-efficacy and the commonly used measures of this concept and were limited to the older adult population. RESULTS: In total, 848 articles were screened, with 20 studies proceeding to data extraction. The modification of general self-efficacy in older adults appears possible, with 7 out of the 20 included studies reporting improvements postintervention. Despite issues relating to the quality of included studies and the generalisability of their results, several aspects of intervention design coincided with intervention success, including intervention duration, and employing sufficiently-qualified staff. CONCLUSIONS: Future research must address the generalisability issues identified in this review. Studies comparing the effectiveness of individual- and group-based interventions, the efficacy of remote delivery platforms and the possibility for long-term transfer of any improvements are needed to contribute the high-quality data required for policy and practice decisions in this area.
