Build It and They Will Come: Interdisciplinary Wellness Clinics in Low-Income Senior Housing.

PURPOSE: The purpose of this study was to describe the first 4 months of implementation of the University of Maryland Interdisciplinary Wellness Clinic (UM-IWC). The UM-IWC provided health care services that are difficult for older adults in low-income senior housing communities to access. DESIGN: This was a descriptive study including four low-income communities. METHODS: Measures included health information, participation, and services provided. FINDINGS: A total of 165 residents were seen (44%). The residents were mostly female (80%), Black (63%), and non-Hispanic (83%), with an average age of 77 years. We provided 253 patient visits with 98 residents seen once, 38 twice, 19 three times, and 10 four times. Visits included 165 intake assessments, 61 immunizations, 193 blood pressure checks, 28 foot care treatments, 12 cerumen removals, 12 completions of advance directives, 14 Annual Wellness Visits, and 3 home visits for acute medical problems. CONCLUSIONS: There was strong engagement of the residents, and we were able to provide a large number of services that were not easily accessible to these individuals. Future work will focus on increasing and maintaining the engagement of residents and sustainability of the clinics.

Faculty Behaviors and Beliefs About Teaching Gun Violence Prevention in Undergraduate Nursing Programs.

BACKGROUND: Gun violence is a public health crisis, but nurses report receiving little education related to gun violence prevention (GVP). PURPOSE: This study aimed to describe undergraduate nursing faculty teaching behaviors and perceptions related to GVP and explore factors associated with teaching it. METHODS: A cross-sectional survey design was used. RESULTS: Less than one-third of faculty taught GVP. Knowledge, confidence, and beliefs were significantly associated with teaching GVP. Most were favorable to include GVP in curricula and agreed assessing for gun access, counseling about safe gun storage, and counseling about lethal means restriction should be taught. Key barriers included content saturation, political atmosphere, lack of educational materials, and lack of topic expertise. CONCLUSION: Faculty agree that GVP should be taught, but most do not teach it in undergraduate nursing programs. Faculty development programs focused on GVP and support from national nursing organizations may decrease barriers in incorporating GVP into curricula.

Feasibility of aging in place clinics in low income senior housing.

The purpose of this study was to describe the feasibility of implementing interdisciplinary senior housing clinics. Feasibility was based on evidence of resident participation, services provided, improvement in clinical outcomes and sustaining clinics over time. Data were collected prospectively in four senior housing communities which included approximately 375 residents 60 years of age and older. Over the 12-month implementation period, 228 residents were seen, 61 % of all residents. We gave 131 immunizations, checked 576 blood pressures, completed 92 foot care treatments, 69 hearing evaluations and cerumen removal, completed 16 advance directives, 119 Annual Wellness Visits, and 13 assessments for acute medical problems. Overall, 87 individuals (38 %) had a decrease in their blood pressures, 121 (54 %) maintained their pressures and 19 (8 %) had increases in blood pressures. We reached over half of the residents living in these communities and estimated we could financially maintain the clinics with reimbursement based on billing.

Understanding and Harnessing Nanoscale Immiscibility in Ru-In Alloys for Selective CO2 Hydrogenation.

Bimetallic alloys made from immiscible elements are characterized by their tendency to segregate on the macroscopic scale, but their behavior is known to change at the nanoscale. Here, we demonstrate that in the Ru-In system, In atoms preferentially decorate the surface of 6 nm Ru nanoparticles, forming Ru-In superficial immiscible alloys. This surface decoration dramatically affects the catalytic performance of the system, even at small atomic fractions of In added to Ru. The interfaces between Ru and In enabled unexplored methanol productivity from CO2 hydrogenation, which outperformed not only the individual constituents but also ordered RuIn3 intermetallic alloys. Our work highlights that the formation of superficial immiscible alloys could offer new insights into the understanding and design of heterogeneous catalysts.

Testing the feasibility and preliminary efficacy of Meaningful Activity for Managing Behavioral Symptoms of Distress (MAC-4-BSD) intervention for residents with dementia in assisted living: Protocol description.

The purpose of this manuscript is to describe the protocol for an Alzheimer's Association-funded cluster randomized trial that focuses on engaging assisted living residents with dementia in meaningful activity to help address their behavioral symptoms of distress using a theoretically based approach, Meaningful Activity for Managing Behavioral Symptoms of Distress (MAC-4-BSD). The development of MAC-4-BSD was based on the Social Ecological Model and Social Cognitive Theory. The MAC-4-BSD intervention includes the following four steps: (1) Assessment of the assisted living physical environment and policies to facilitate meaningful activity; (2) Education of staff about implementation of meaningful activity; (3) Assessment of resident preferences and goals for meaningful activity; (4) Mentoring and motivating staff and residents to facilitate engagement in meaningful activity. The overall aim of this study will be to determine the feasibility and preliminary efficacy of implementing the MAC-4-BSD intervention and test whether it will improve residents' engagement in meaningful activity, behavioral symptoms of distress, and quality of life as well as the environment and policies to promote meaningful activity in assisted living.

Acceptability of Audiovestibular Assessment in the Home-A Patient Survey.

The COVID-19 pandemic dramatically changed health service delivery with vulnerable patients advised to isolate and appointments provided virtually. This change affected recruitment into an observational cohort study, undertaken at a single site, where participants with mitochondrial disorders were due to have specialist hospital-based audiovestibular tests. To ensure study viability, the study protocol was amended to allow home-based assessment for vulnerable participants. Here, we report outcomes of an online survey of participants who underwent home-based assessment, related to the experience, perceived benefits, and drawbacks of home audiovestibular assessments. Seventeen participants underwent home-based neuro-otological assessment, due to the need to isolate during COVID-19. Following the assessment, 16 out of 17 participants completed an anonymised online survey to share their experiences of the specialist home-based assessment. One hundred percent of participants rated the home-based assessment 'very positively' and would recommend it to others. Sixty-three percent rated it better than attending hospital outpatient testing settings. The benefits included no travel burden (27%) and reduced stress (13%). A majority reported no drawbacks in having the home visit. The patient-reported feedback suggests a person-centred approach where audiovestibular assessments are conducted in their homes is feasible for patients, acceptable and seen as beneficial to a vulnerable group of patients.

Nursing Home Characteristics Associated with Antipsychotic Prescribing After Implementation of the National Antipsychotic Reduction Initiative (ARI).

OBJECTIVES: To describe nursing home (NH) characteristics associated with antipsychotic use and test whether associations changed after implementation of the National Partnership to Improve Dementia Care's antipsychotic reduction initiative (ARI). METHODS: Longitudinal quasi-experimental design using data from multiple sources and piecewise linear mixed models were used for statistical analyses. RESULTS: There was a significant decrease in monthly antipsychotic use across the study period (pre-ARI b = -0.0003, p <.001; post-ARI b = -0.0012, p <.001), which held after adjusting for NH characteristics. Registered nurse hours (b = -0.0026, p <.001), licensed practical nurse hours (b = -0.0019, p <.001), facility chain membership (b = -0.0013, p <.01), and health inspection ratings (b = -0.0003, p >.01) were associated with decreased antipsychotic use. Post-ARI changes in associations between NH characteristics and antipsychotic use were small and not statistically significant. CONCLUSIONS: Decreases in antipsychotic use were associated with most NH characteristics, and associations persisted post-ARI. Further research is warranted to examine the interactions between ARI policy and NH characteristics on antipsychotic prescribing, as well as other NH factors, such as facility prescribing cultures and clinical specialty of staff. CLINICAL IMPLICATIONS: Decreases in monthly antipsychotic use were observed following the ARI. The decreases in monthly antipsychotic use were associated with most NH characteristics, and these associations persisted during the post-ARI period.

Examining pain, function, behavioral symptoms and associations with engagement in meaningful activity for residents with dementia in assisted living.

OBJECTIVES: The purpose of this study was to examine factors associated with engagement in meaningful activity among residents with dementia in assisted living. We hypothesized that greater functional independence, less pain, and lower behavioral and psychological symptom severity would be associated with higher engagement in meaningful activity after controlling for residents' age, gender, comorbidities, and cognition. Understanding factors associated with engagement in meaningful activity can help to inform strategies for optimizing engagement among residents with dementia in assisted living. METHOD: This descriptive study used baseline data from a randomized controlled trial, Meaningful Activity for Managing Behavioral Symptoms of Distress (MAC-4-BSD). Linear regression was used to examine factors associated with engagement in meaningful activity. RESULTS: A total of 71 residents from 5 assisted living settings were included in the sample. Most participants were female (n = 52, 73%), White (n = 62, 87%), and mean age was 85 years old (SD = 8.2). Controlling for age, gender, comorbidities, and cognition, pain was significantly associated with engagement in meaningful activity (b= -2.09, p < 0.05). There were no associations found between function and behavioral symptoms with engagement in meaningful activity. CONCLUSION: Findings from this study show that pain is a significant factor that is negatively associated with residents' engagement in meaningful activity. Ongoing research is needed to help improve pain management for residents with dementia in assisted living and support their engagement in meaningful activity.

Recovery of isolated lithium through discharged state calendar ageing.

Rechargeable Li-metal batteries have the potential to more than double the specific energy of the state-of-the-art rechargeable Li-ion batteries, making Li-metal batteries a prime candidate for next-generation high-energy battery technology1-3. However, current Li-metal batteries suffer from fast cycle degradation compared with their Li-ion battery counterparts2,3, preventing their practical adoption. A main contributor to capacity degradation is the disconnection of Li from the electrochemical circuit, forming isolated Li4-8. Calendar ageing studies have shown that resting in the charged state promotes further reaction of active Li with the surrounding electrolyte9-12. Here we discover that calendar ageing in the discharged state improves capacity retention through isolated Li recovery, which is in contrast with the well-known phenomenon of capacity degradation observed during the charged state calendar ageing. Inactive capacity recovery is verified through observation of Coulombic efficiency greater than 100% on both Li||Cu half-cells and anode-free cells using a hybrid continuous-resting cycling protocol and with titration gas chromatography. An operando optical setup further confirms excess isolated Li reactivation as the predominant contributor to the increased capacity recovery. These insights into a previously unknown pathway for capacity recovery through discharged state resting emphasize the marked impact of cycling strategies on Li-metal battery performance.

A diagnostic framework to identify vestibular involvement in multi-sensory neurological disease.

BACKGROUND AND PURPOSE: Identifying vestibular causes of dizziness and unsteadiness in multi-sensory neurological disease can be challenging, with problems typically attributed to central or peripheral nerve involvement. Acknowledging vestibular dysfunction as part of the presentation provides an opportunity to access targeted vestibular rehabilitation, for which extensive evidence exists. A diagnostic framework was developed and validated to detect vestibular dysfunction, benign paroxysmal positional vertigo or vestibular migraine. The specificity and sensitivity of the diagnostic framework was tested in patients with primary mitochondrial disease. METHODS: Adults with a confirmed diagnosis of primary mitochondrial disease were consented, between September 2020 and February 2022. Participants with and without dizziness or unsteadiness underwent remote physiotherapy assessment and had in-person detailed neuro-otological assessment. The six framework question responses were compared against objective neuro-otological assessment or medical notes. The output was binary, with sensitivity and specificity calculated. RESULTS: Seventy-four adults completed the study: age range 20-81 years (mean 48 years, ±SD 15.05 years); ratio 2:1 female to male. The framework identified a vestibular diagnosis in 35 participants, with seven having two diagnoses. The framework was able to identify vestibular diagnoses in adults with primary mitochondrial disease, with a moderate (40-59) to very high (90-100) sensitivity and positive predictive value, and moderate to high (60-74) to very high (90-100) specificity and negative predictive value. CONCLUSIONS: Overall, the clinical framework identified common vestibular diagnoses with a moderate to very high specificity and sensitivity. This presents an opportunity for patients to access effective treatment in a timely manner, to reduce falls and improve quality of life.

Psychometric Properties of the Resilience Scale in Older Adults Post-Hip Fracture.

Objectives: The purpose of this study was to evaluate the psychometric properties of the modified 25-item Resilience Scale (RS-25) in older adults post-hip fracture using Rasch analysis. Methods: This was a descriptive study using baseline data from the Seventh Baltimore Hip Studies (BHS-7). There were 339 hip fracture patients included in this analysis. Results: Findings suggest there was support for reliability of the measure based on person and item separation index. The INFIT and OUTFIT statistics for testing validity were all in the acceptable range indicating that each item on the modified RS-25 fits the appropriate concept. There was no evidence of Differential Item Functioning (DIF) between genders. Conclusions: This study demonstrated evidence that the modified RS-25 is a reliable and valid measure to evaluate resilience among older adults post-hip fracture and therefore can be used in this population in clinical practice and research.

Exploring Factors Associated With Resilience and Physical Activity in Older Men and Women Post-Hip Fracture.

This study aimed to test a model of factors associated with resilience and physical activity post-hip fracture and compare model fit between men and women. We used data from the seventh Baltimore Hip Study that included 339 participants. Model testing indicated that health status (men: ß = .237, p = .002; women: ß = .265, p = <.001), depression (men: ß = -.245, p = .001; women: ß = -.241, p = <.001), and optimism (men: ß = .320, p = <.001; women: ß = .282, p = <.001) were associated with resilience in men and women, but resilience was only associated with physical activity in men (ß = .203, p = .038) and not in women. Social interaction was related to physical activity only among women (ß = .206, p = .044). This study provides support for the relationship between resilience and physical activity at least among men.

Model Testing of the Factors that are Associated with Care Interactions among Nursing Home Residents with Dementia.

OBJECTIVE: The purpose of this study was to test a model of the resident and community factors that are associated with quality of care interactions among nursing home (NH) residents living with dementia and test for invariance between model fit when tested with the Black versus White residents and female versus male residents. It was hypothesized that resident age, gender, race, pain, comorbidities, quality of life, resistiveness to care, function, cognition, community profit status, overall community star rating, community size, and staffing star rating would be directly and/or indirectly associated with quality of care interactions. It was also hypothesized that the model fit would be invariant by resident race and gender. DESIGN: This was a secondary data analysis using baseline, cross-sectional data from the Evidence Integration Triangle for Behavioral and Psychological Symptoms of Dementia (EIT-4-BPSD) intervention study. SETTING AND PARTICIPANTS: The study included 528 residents from 55 NH facilities. METHODS: Descriptive statistics and structural equation modeling was used to test the proposed model. RESULTS: The results showed that the final model with significant paths only had a poor fit to the data (χ2/df = 10.79, comparative fit index = 0.57, Tucker-Lewis index = 0.15, normed fit index = 0.57, root mean square error of approximation = 0.13). However, the findings indicated that comorbidities, pain, profit status, and overall community star rating were significantly associated with quality of care interactions. There was no difference in model fit between Black residents versus White residents, and between male versus female residents. CONCLUSIONS AND IMPLICATIONS: This study suggests factors that may influence quality of care interactions. Managing comorbidities, managing pain, and supporting higher quality of care in NH communities will likely help increase the frequency of positive care interactions. These findings can inform future interventions and training curricula for NH care staff to promote positive care interactions.

Cancer Cell Culture: The Basics and Two-Dimensional Cultures.

Despite significant advances in investigative and therapeutic methodologies for cancer, 2D cell culture remains an essential and evolving competency in this fast-paced industry. From basic monolayer cultures and functional assays to more recent and ever-advancing cell-based cancer interventions, 2D cell culture plays a crucial role in cancer diagnosis, prognosis, and treatment. Research and development in this field call for a great deal of optimization, while the heterogenous nature of cancer itself demands personalized precision for its intervention. In this way, 2D cell culture is ideal, providing a highly adaptive and responsive platform, where skills can be honed and techniques modified. Furthermore, it is arguably the most efficient, economical, and sustainable methodology available to researchers and clinicians alike.In this chapter, we discuss the history of cell culture and the varying types of cell and cell lines used today, the techniques used to characterize and authenticate them, the applications of 2D cell culture in cancer diagnosis and prognosis, and more recent developments in the area of cell-based cancer interventions and vaccines.

Dissolution of the Solid Electrolyte Interphase and Its Effects on Lithium Metal Anode Cyclability.

At >95% Coulombic efficiencies, most of the capacity loss for Li metal anodes (LMAs) is through the formation and growth of the solid electrolyte interphase (SEI). However, the mechanism through which this happens remains unclear. One property of the SEI that directly affects its formation and growth is the SEI's solubility in the electrolyte. Here, we systematically quantify and compare the solubility of SEIs derived from ether-based electrolytes optimized for LMAs using in-operando electrochemical quartz crystal microbalance (EQCM). A correlation among solubility, passivity, and cyclability established in this work reveals that SEI dissolution is a major contributor to the differences in passivity and electrochemical performance among battery electrolytes. Together with our EQCM, X-ray photoelectron spectroscopy (XPS), and nuclear magnetic resonance (NMR) spectroscopy results, we show that solubility depends on not only the SEI's composition but also the properties of the electrolyte. This provides a crucial piece of information that could help minimize capacity loss due to SEI formation and growth during battery cycling and aging.

The Association of Cognitive Impairment With Depressive Symptoms, Function, and Pain in Hospitalized Older Patients With Dementia.

This study examined the associations between cognition and depressive symptoms, function, and pain among hospitalized older patients with dementia. We utilized baseline data of 461 hospitalized older patients with dementia who participated in an intervention study implementing Family-centered Function-focused Care (Fam-FFC) and conducted stepwise linear regression. On average, the participants (males = 189; 41% and females = 272; 59%) were 81.64 years old (Standard Deviation, SD = 8.38). There was a statistically significant association of cognition with depressive symptoms (b = -0.184, p < .001), functional status (b = 1.324, p < .001), and pain (b = -0.045, p < .001) when controlling for covariates. This study utilized a large sample of a relatively underrepresented population, hospitalized older adults with dementia, and addressed a topic with great clinical significance. Specific focus on testing and implementing best practices or interventions to support the clinical outcomes, and the cognitive function of hospitalized older adults with dementia is warranted in both practice and research.

The Association Between Engagement in Activities of Daily Living and Care Interactions for Residents Living With Dementia.

BACKGROUND: Care interactions are essential to residents with dementia. PURPOSE: The purpose of the study was to describe the characteristics and quality of staff-resident care interactions among nursing home residents living with dementia and to test whether the quality of staff-resident care interactions varied by resident level of engagement in the interaction. Specifically, it was hypothesized that controlling for age, gender, comorbidities, cognition, and function, actively engaged residents would have more positive care interactions with staff compared with passively engaged residents. METHODS: This was a secondary data analysis using baseline data from the Evidence Integration Triangle for Behavioral and Psychological Symptoms of Dementia intervention study. RESULTS: A total of 532 residents were included. Actively engaged residents had significantly more positive interactions compared to passively engaged residents. CONCLUSIONS: Passively engaged residents may be at risk to receive poor quality care interactions. Strategies and interventions to optimize care interactions for these individuals are needed.

Unintended impacts of a national antipsychotic reduction initiative among nursing facility residents with and without Alzheimer's disease.

BACKGROUND: In July 2012, the Centers for Medicare & Medicaid services launched an antipsychotic reduction initiative (ARI) to improve care for nursing facility residents with Alzheimer's disease and related dementias (ADRD). We examined the impact of this policy on antipsychotic and psychotropic medication (PM) utilization and diagnosis patterns in long-stay nursing facility residents with ADRD and other conditions in which antipsychotics are indicated. METHODS: Using an 80% sample of fee-for-service Medicare beneficiaries with Part D, we conducted a retrospective cohort study of nursing facility residents with ADRD, bipolar disorder, psychosis, Parkinson's disease, and residents exempt from the policy due to diagnoses of schizophrenia, Tourette syndrome, and/or Huntington's disease. We used interrupted time-series analyses to compare changes in diagnoses, antipsychotic use, and PM utilization before (January 1, 2011-June 30, 2012) and after (July 1, 2012-September 30, 2015) ARI implementation. RESULTS: We identified 874,487 long-stay nursing facility residents with a diagnosis of ADRD (n = 358,518), exempt (n = 92,859), bipolar (n = 128,298), psychosis (n = 93,402), and Parkinson's disease (n = 80,211). In all cohorts, antipsychotic use declined prior to the ARI; upon policy implementation, antipsychotic use reductions were sustained throughout the study period, including statistically significant ARI-associated accelerated declines in all cohorts. PM changes varied by cohort, with ARI-associated increases in non-benzodiazepine sedatives and/or muscle relaxants noted in ADRD, psychosis, and Parkinson's cohorts. Although anticonvulsant use increased throughout the study period in all groups, with the exception of the bipolar cohort, these increases were not associated with ARI implementation. Findings are minimally explained by increased post-ARI membership in the psychosis and Parkinson's cohorts. CONCLUSIONS: Our study documents antipsychotic use significantly declined in non-ADRD clinical and exempt cohorts, where such reductions may not be clinically warranted. Furthermore, ARI-associated compensatory increases in PMs do not offset these reductions. Changes in PM utilization and diagnostic make-up of residents using PMs require further investigation to assess the potential for adverse clinical and economic outcomes.

Prevalence of genetically confirmed skeletal muscle channelopathies in the era of next generation sequencing.

We provide an up-to-date and accurate minimum point prevalence of genetically defined skeletal muscle channelopathies which is important for understanding the population impact, planning for treatment needs and future clinical trials. Skeletal muscle channelopathies include myotonia congenita (MC), sodium channel myotonia (SCM), paramyotonia congenita (PMC), hyperkalemic periodic paralysis (hyperPP), hypokalemic periodic paralysis (hypoPP) and Andersen- Tawil Syndrome (ATS). Patients referred to the UK national referral centre for skeletal muscle channelopathies and living in UK were included to calculate the minimum point prevalence using the latest data from the Office for National Statistics population estimate. We calculated a minimum point prevalence of all skeletal muscle channelopathies of 1.99/100 000 (95% CI 1.981-1.999). The minimum point prevalence of MC due to CLCN1 variants is 1.13/100 000 (95% CI 1.123-1.137), SCN4A variants which encode for PMC and SCM is 0.35/100 000 (95% CI 0.346 - 0.354) and for periodic paralysis (HyperPP and HypoPP) 0.41/100 000 (95% CI 0.406-0.414). The minimum point prevalence for ATS is 0.1/100 000 (95% CI 0.098-0.102). There has been an overall increase in point prevalence in skeletal muscle channelopathies compared to previous reports, with the biggest increase found to be in MC. This can be attributed to next generation sequencing and advances in clinical, electrophysiological and genetic characterisation of skeletal muscle channelopathies.
