Sleep disturbances and interrelationship between persons with dementia and family caregivers: The lived experiences of Korean American Dyads.

BACKGROUND: Little research has investigated sleep quality in dyadic interrelationships between persons with dementia (PWD) and family caregivers, particularly among immigrant ethnic minorities, such as Korean Americans. PURPOSE: The study aimed to describe lived experiences of sleep disturbances and sleep interrelationships between Korean American PWD and their family caregivers. METHODS: A descriptive qualitative design used semi-structured interviews with cohabitating PWD-caregiver dyads. RESULTS: Eleven Korean American dyads participated (PWD mean age: 82.7, SD=2.3; caregivers mean age: 69.1, SD=10.2). Major themes included (1) linked sleep disturbances between PWD and caregivers, (2) interrelationship in dyads, (3) language challenges within and outside the dyads, and (4) strategies that improve sleep quality for dyads. CONCLUSION: Findings demonstrated bidirectional influences in dyadic sleep disturbances, where caregiving reciprocally impacted PWD sleep as part of an interactional unit. Communication barriers and limited community resources posed challenges for these dyads. Future sleep interventions should consider culturally competent, dyadic approaches.

Gait and/or balance disturbances associated with Alzheimer's dementia among older adults with amnestic mild cognitive impairment: A longitudinal observational study.

AIMS: To explore whether gait and/or balance disturbances are associated with the onset of Alzheimer's dementia (AD) among older adults with amnestic mild cognitive impairment (MCI). DESIGN: This study employed a longitudinal retrospective cohort design. METHODS: We obtained data from the National Alzheimer's Coordinating Center's Uniform Data Set collected from 35 National Institute on Aging Alzheimer's Disease Research Centers between September 2005 and December 2021. The mean age of participants (n = 2692) was 74.5 years with women making up 47.2% of the sample. Risk of incident AD according to baseline gait and/or balance disturbances as measured using the Postural Instability and Gait Disturbance Score, a subscale of the Unified Parkinson's Disease Rating Scale Motor Score, was examined by the Cox proportional hazards regression models adjusting for baseline demographics, medical conditions and study sites. The mean follow-up duration was 4.0 years. RESULTS: Among all the participants, the presence or the severity of gait and/or balance disturbances was associated with an increased risk of AD. The presence or the severity of gait and/or balance disturbances was associated with a higher risk of Alzheimer's dementia among the subgroups of female and male participants. CONCLUSION: Gait and/or balance disturbances may increase the risk of developing AD, regardless of sex. IMPACT: Gait and/or balance disturbances among community-dwelling older adults with amnestic MCI may need to be frequently assessed by nurses to identify potential risk factors for cognitive decline. NO PATIENT OR PUBLIC CONTRIBUTION: Given the secondary analysis, patients, service users, caregivers or members of the public were not directly involved in this study.

Facilitators and Challenges to Exergaming: Perspectives of Patients With Heart Failure.

BACKGROUND: Few investigators have explored challenges and facilitators to exergaming, essential factors to exergaming adherence, among patients with heart failure. OBJECTIVES: In this qualitative study, we explored facilitators and challenges using a home-based exergame platform, the Nintendo Wii Sports, in patients with heart failure. METHODS: Semistructured face-to-face interviews were conducted in 13 participants given a diagnosis of heart failure (age range, 34-69 years). Participants were asked about their experiences with exergaming. Transcribed interviews were analyzed with content analysis. RESULTS: The following 4 facilitators were identified: (1) enjoyment and competition motivated gaming, (2) accessibility at home gave freedom and lowered participants' barriers to exercise, (3) physical benefits when decreasing sedentary lifestyle, and (4) psychosocial benefits on stress, mood, and family interactions. Challenges included (1) diminished engagement over time due to boredom playing similar games and (2) frustrations due to game difficulty and lack of improvement. CONCLUSION: Exergaming can increase individuals' physical activity because of easy accessibility and the fun and motivating factors the games offer. Participants initially found exergaming enjoyable and challenging. However, engagement diminished over time because of boredom from playing the same games for a period of time. Participants' preferences and capacities, participants' past experiences, and social support must be considered to avoid boredom and frustrations. Future studies are warranted to determine adherence to exergaming among patients with heart failure and, ultimately, increased overall well-being and healthcare delivery in this patient population.

A novel conceptual model of trauma-informed care for patients with post-acute sequelae of SARS-CoV-2 illness (PASC).

AIM: This paper proposes a novel, trauma-informed, conceptual model of care for Post-Acute Sequelae of COVID-19 illness (PASC). DESIGN: This paper describes essential elements, linkages and dimensions of the model that affect PASC patient experiences and the potential impact of trauma-informed care on outcomes. DATA SOURCES: PASC is a consequence of the global pandemic, and a new disease of which little is known. Our model was derived from the limited available studies, expert clinical experience specific to PASC survivors and publicly available social media narratives authored by PASC survivors. IMPLICATIONS FOR NURSING: The model provides a critical and novel framework for the understanding and care of persons affected by PASC. This model is aimed at the provision of nursing care, with the intention of reducing the traumatic impacts of the uncertain course of this disease, a lack of defined treatment options and difficulties in seeking care. The use of a trauma-informed care approach to PASC patients can enhance nurses' ability to remediate and ameliorate both the traumatic burden of and the symptoms and experience of the illness. CONCLUSION: Applying a trauma-informed perspective to care of PASC patients can help to reduce the overall burden of this complex condition. Owing to the fundamentally holistic perspective of the nursing profession, nurses are best positioned to implement care that addresses multiple facets of the PASC experience. IMPACT: The proposed model specifically addresses the myriad ways in which PASC may affect physical as well as mental and psychosocial dimensions of health. The model particularly seeks to suggest means of supporting patients who have already experienced a life-threatening illness and are now coping with its long-term impact. Since the scope of this impact is not yet defined, trauma-informed care for PASC patients is likely to reduce the overall health and systems burdens of this complex condition.

A Culturally and Linguistically Appropriate Telephone Support Intervention for Diverse Family Caregivers of Persons With Dementia During the COVID-19 Pandemic.

Caregivers of persons with dementia (PWDs) were socially isolated with little support during the COVID-19 pandemic "Stay-At-Home" order in the United States. To enhance social and emotional connection for diverse caregivers, a culturally/linguistically appropriate telephone intervention provided compassionate listening, mindful breathing, and COVID-19 safety education. The study purpose was to understand caregiving challenges and to evaluate the intervention for caregivers during the early pandemic using a qualitative approach. Twenty-three caregivers participated in the intervention provided by bilingual research assistants for 3 months. Call logs were used to describe the caregivers' dialogue. Thematic analysis identified (a) the challenges, including fear of coronavirus disease, providing around-the-clock care, and forced isolation and negative emotions; and (b) caregivers' experience with the intervention, including connecting with the outside, relief from emotional stress, reliable COVID-19 information, and reinformed caregiving skills. Results suggest that the telephone support was of benefit to diverse caregivers of PWDs during the pandemic by promoting social connection and reducing emotional distress.

Personalized Risk Prediction for 30-Day Readmissions With Venous Thromboembolism Using Machine Learning.

PURPOSE: The aim of the study was to develop and validate machine learning models to predict the personalized risk for 30-day readmission with venous thromboembolism (VTE). DESIGN: This study was a retrospective, observational study. METHODS: We extracted and preprocessed the structured electronic health records (EHRs) from a single academic hospital. Then we developed and evaluated three prediction models using logistic regression, the balanced random forest model, and the multilayer perceptron. RESULTS: The study sample included 158,804 total admissions; VTE-positive cases accounted for 2,080 admissions from among 1,695 patients (1.31%). Based on the evaluation results, the balanced random forest model outperformed the other two risk prediction models. CONCLUSIONS: This study delivered a high-performing, validated risk prediction tool using machine learning and EHRs to identify patients at high risk for VTE after discharge. CLINICAL RELEVANCE: The risk prediction model developed in this study can potentially guide treatment decisions for discharged patients for better patient outcomes.

Relationships within MOMS Orange County care coordinated home visitation perinatal program.

PURPOSE: The study aimed to examine how registered nurses (RNs) and paraprofessional home visitors (PHVs) work together as a team to care for underserved perinatal women in a coordinated home visitation program. DESIGN AND METHODS: Qualitative methods were used to understand the perspectives of three RNs and twenty PHVs who worked at MOMS Orange County, a community-based perinatal health program. Individual one-on-one interviews were administered with the RNs and focus groups with the PHVs. Qualitative content analysis was conducted to synthesize themes. RESULTS: RNs perceived themselves as educators, mentors, and supervisors. PHVs thought of themselves as supporters, coaches, and advocates. Interdependence and proactive communication were favorable characteristics of the relationship in which RNs trained PHVs to provide health education. The positive interactions between RNs and PHVs appeared to enhance the client-healthcare provider connection. CONCLUSIONS: Our study is one of the first to describe relationships and communication patterns among the healthcare team in a coordinated home visitation program in the United States. Future studies should examine how additional members of the team, including clients and healthcare providers, view their experiences with a home visitation program.

"I was Confused About How to Take Care of Mom Because this Disease is Different Everyday": Vietnamese American Caregivers' Understanding of Alzheimer's Disease.

Family members provide the majority of caregiving to individuals living with Alzheimer's disease (AD) and related dementias. Asian American families are disproportionately impacted by the burden of caregiving due to limited knowledge about the disease in this community. This study explored how Vietnamese American caregivers understand AD and provide care to family members with AD. Twenty caregivers who have provided care to a family member with AD participated in a semi-structured qualitative interview. Data were analyzed using thematic analysis. Several themes were identified in the caregivers' understanding of AD: (a) "Now I know:" the disruptions, shocks and surprises leading up to the initial diagnosis; (b) The frustrations of managing family members' cognitive impairments; (c)"Going with the flow:" challenges in managing personality and behavioral changes; (d) The exhaustion of around-the-clock caregiving; (e)"Taking it day by day" in the face of progressively worsening symptoms. Underlining the participants' descriptions of AD was a shared understanding of the progressively worsening, complex and unpredictable nature of the disease that makes it challenging for family caregivers on a daily basis. Findings provide important implications for healthcare workers' outreach to Vietnamese American families to ease the caregiving experience through culturally-responsive education, thereby enhancing the families' ability to recognize the early symptoms and seek appropriate help.

"Living happily despite having an illness": Perceptions of healthy aging among Korean American, Vietnamese American, and Latino older adults.

BACKGROUND/OBJECTIVE: The growingly diverse aging population presents a challenge for the geriatric workforce, particularly its capacity to effectively respond to the sociocultural and linguistic needs of ethnic minority older adults. Informed by research on the importance of culturally-competent care in reducing racial and ethnic health disparities, this study sought to understand the meaning of healthy aging from the perspectives of Korean American, Vietnamese American, and Latino older adults. METHODS: Interviews were conducted with 30 participants recruited from community-based organizations in Southern California. RESULTS: Several dimensions emerged in the participants' understanding of healthy aging: (1) having good physical and mental health (2) optimism and acceptance; (3) social connectedness; (4) taking charge of one's health; and (5) independence and self-worth. CONCLUSIONS: Results could inform the development of a culturally-responsive geriatric healthcare system that takes into account older adults' beliefs, preferences, and needs to promote successful aging.

Caregiving Experience of Dementia among Korean American Family Caregivers.

Dementia is a major public health problem affecting 5.5 million people in USA. This qualitative study explored the caregiving experience of Korean American (KA) families of persons with dementia (PWD). Adult KA caregivers of PWD (n = 18) were recruited for semi-structured interviews. Thematic analysis yielded four themes: challenges in finding resources, struggling with mental health issues, traveling the path of acceptance, and finding ways to survive. Due to the language barrier, most KA caregivers reported using Korean Internet for information on dementia and caregiving. Some traveled to South Korea seeking medical assistance for dementia (medical tourism). Importantly, some KA caregivers expressed suicidal thoughts and depression. Unexpectedly, familism prevented help seeking and possible relief from their difficulties. There is an urgent need to improve access to dementia care services and education for the KA community. Building a trusting relationship with healthcare providers is even more important for KA caregivers to address their mental health concerns.

Anterior thalamic nuclei lesions have a greater impact than mammillothalamic tract lesions on the extended hippocampal system.

The anterior thalamic nuclei (ATN), mammillary bodies and their interconnecting fiber tract, the mammillothalamic tract (MTT), are important components of an extended hippocampal circuit for episodic memory. In humans, damage to the MTT or ATN in many disorders is associated with severe anterograde amnesia and it is assumed that their influence on memory is functionally equivalent. The relative influence of these two structures on memory has not, however, been assessed explicitly. Here, a direct comparison found that only ATN lesions impaired spatial reference memory in rats. ATN lesions produced more severe deficits on spatial working memory and reduced zif268 expression to a greater degree and in more corticolimbic sites than did MTT lesions. Conversely, MTT lesions reduced NeuN cell counts in all three subregions of the MB to a greater extent than did ATN lesions, so their relative impact cannot be explained by retrograde neuropathology of the MB. Hence ATN injury causes a more critical dysfunction than would be expected by an emphasis on the indirect influence of brainstem inputs to the extended memory system. The greater ATN lesion deficits found here may represent the consequence of disruption to the direct connections of the ATN with both hippocampal and cortical sites.

Effective behavioral intervention strategies using mobile health applications for chronic disease management: a systematic review.

BACKGROUND: Mobile health (mHealth) has continuously been used as a method in behavioral research to improve self-management in patients with chronic diseases. However, the evidence of its effectiveness in chronic disease management in the adult population is still lacking. We conducted a systematic review to examine the effectiveness of mHealth interventions on process measures as well as health outcomes in randomized controlled trials (RCTs) to improve chronic disease management. METHODS: Relevant randomized controlled studies that were published between January 2005 and March 2016 were searched in six databases: PubMed, CINAHL, EMBASE, the Cochrane Library, PsycINFO, and Web of Science. The inclusion criteria were RCTs that conducted an intervention using mobile devices such as smartphones or tablets for adult patients with chronic diseases to examine disease management or health promotion. RESULTS: Of the 12 RCTs reviewed, 10 of the mHealth interventions demonstrated statistically significant improvement in some health outcomes. The most common features of mHealth systems used in the reviewed RCTs were real-time or regular basis symptom assessments, pre-programed reminders, or feedbacks tailored specifically to the data provided by participants via mHealth devices. Most studies developed their own mHealth systems including mobile apps. Training of mHealth systems was provided to participants in person or through paper-based instructions. None of the studies reported the relationship between health outcomes and patient engagement levels on the mHealth system. CONCLUSIONS: Findings from mHealth intervention studies for chronic disease management have shown promising aspects, particularly in improving self-management and some health outcomes.

Clinical nurses' knowledge and practice of venous thromboembolism risk assessment and prevention in South Korea: a cross-sectional survey.

AIMS AND OBJECTIVES: To examine Korean registered nurses' level of perceived knowledge and practice of venous thromboembolism risk assessment as well as prevention, self-efficacy in venous thromboembolism care and actual knowledge of venous thromboembolism. BACKGROUND: For hospitalised patients, venous thromboembolism is a preventable clinical disorder. Caring for venous thromboembolism patients requires coordination across multiple providers and settings. Clinical nurses can play a major role in improving venous thromboembolism prevention care, assessing venous thromboembolism risks and providing appropriate prophylactic measures to those who are at risk for venous thromboembolism. DESIGN: A cross-sectional descriptive study. METHODS: Anonymous paper-based surveys were conducted for a convenience sample of registered nurses' (n = 452) from two university-affiliated hospitals in South Korea. RESULTS: The majority of participants indicated that their overall self-rated venous thromboembolism knowledge was 'fair', while only 2·4% rated it as 'very good' or 'excellent'. The overall mean score of the venous thromboembolism knowledge questions was 50·9 (±13·0) of a possible score of 100. The mean score of self-efficacy in practising venous thromboembolism prevention/prophylaxis was 3·0 (based on a one to five Likert scale). The self-reported venous thromboembolism assessment performance on patients varied among clinical units. Only 9·3% of participants reported having received in-service venous thromboembolism education from their hospital. CONCLUSIONS: The findings showed that overall venous thromboembolism knowledge and self-efficacy in venous thromboembolism prevention practices of Korean registered nurses' were not highly rated. Korean nurses demonstrated a lack of knowledge about venous thromboembolism, particularly in the areas of venous thromboembolism prophylaxis measures and venous thromboembolism diagnosis methods. RELEVANCE TO CLINICAL PRACTICE: Focused education on venous thromboembolism prevention and risk assessment should be considered a component of continuing education for Korean nurses.

Examining the effects of remote monitoring systems on activation, self-care, and quality of life in older patients with chronic heart failure.

BACKGROUND: The use of remote monitoring systems (RMSs) in healthcare has grown exponentially and has improved the accessibility to and ability of patients to engage in treatment intensification. However, research describing the effects of RMSs on activation, self-care, and quality of life (QOL) in older patients with heart failure (HF) is limited. OBJECTIVE: The aim of this study was to compare the effects of a 3-month RMS intervention on activation, self-care, and QOL of older patients versus a reference group matched on age, gender, race, and functional status (ie, New York Heart Association classification) who received standard discharge instructions after an acute episode of HF exacerbation requiring hospitalization. METHODS: A total of 21 patients (mean age, 72.7 ± 8.9 years; range, 58-83 years; 52.4% women) provided consent and were trained to measure their weight, blood pressure, and heart rate at home with an RMS device and transmit this information every day for 3 months to a centralized information system. The system gathered all data and dispatched alerts when certain clinical conditions were met. RESULTS: The baseline sociodemographic and clinical characteristics of the 2 groups were comparable. Over time, participants in the RMS group showed greater improvements in activation, self-care, and QOL compared with their counterparts. Data showed moderately strong associations between increased activation, self-care, and QOL. CONCLUSION: Our preliminary data show that the use of an RMS is feasible and effective in promoting activation, self-care, and QOL. A larger-scale randomized clinical trial is warranted to show that the RMS is a new and effective method for improving clinical management of older adults with chronic HF.

Translation and evaluation of the Cultural Awareness Scale for Korean nursing students.

BACKGROUND: To evaluate the effectiveness of a curriculum for achieving high levels of cultural competence, we need to be able to assess education intended to enhance cultural competency skills. We therefore translated the Cultural Awareness Scale (CAS) into Korean (CAS-K). The purpose of this study was to evaluate the cross-cultural applicability and psychometric properties of the CAS-K, specifically its reliability and validity. METHODS: A cross-sectional descriptive design was used to conduct the evaluation. A convenience sample of 495 nursing students was recruited from four levels of nursing education within four universities in the city of Daejeon, South Korea. RESULTS: This study provided beginning evidence of the validity and reliability of the CAS-K and the cross-cultural applicability of the concepts underlying this instrument. Cronbach's alpha ranged between 0.59 and 0.86 (overall 0.89) in the tests of internal consistency. Cultural competency score prediction of the experience of travel abroad (r=0.084) and the perceived need for cultural education (r=0.223) suggested reasonable criterion validity. Five factors with eigenvalues >1.0 were extracted, accounting for 55.58% of the variance; two retained the same items previously identified for the CAS. CONCLUSION: The CAS-K demonstrated satisfactory validity and reliability in measuring cultural awareness in this sample of Korean nursing students. The revised CAS-K should be tested for its usability in curriculum evaluation and its applicability as a guide for teaching cultural awareness among groups of Korean nursing students.

Suppression of spontaneous activity before visual response in the primate V1 neurons during a visually guided saccade task.

Visually guided saccadic eye movements are thought to involve multiple stages of processing in diverse brain structures including the primary visual cortex (V1). The variability of neural activity in each of these structures may present ambiguities for downstream stages in identifying sensory and motor signals among spontaneous discharges. The response time of saccadic eye movements made toward a visual target is correlated with the time of the first spikes in V1 that are evoked by the target (Lee et al., 2010). This suggests that downstream neurons receiving the output of V1 are faced with a challenging task of discriminating first spikes of visual response against spontaneous discharge. Here we report a novel response property of the macaque V1 neurons. Immediately before neurons discharge a burst of activity to a visual saccade target, spontaneous discharges were transiently suppressed. This suppression was maximal ∼18 ms after target onset. Based on simulations of artificial spike trains, we propose that the transient suppression enhances temporal contrast for identifying the onset of visual response by increasing the reliability of detection of response onset by downstream neurons, thereby facilitating visually guided behavioral responses.

Asthma characteristics among older adults: using the California health interview survey to examine asthma incidence, morbidity and ethnic differences.

OBJECTIVE: The purpose of this study was to examine the incidence, characteristics of asthma morbidity and care, and ethnic differences that exist in older adults with asthma in California. METHODS: Data were from the 2009 California Health Interview Survey (CHIS). Characteristics of older adults (≥65 years) with and without asthma were compared using population-weighted estimates. Asthma-specific variables were compared among different ethnic groups. Multivariate analyses were preformed to determine factors associated with asthma status, asthma episodes/attacks, asthma symptom frequency and emergency department (ED) visits due to asthma. RESULTS: Asthma was present in 8.1% of older adults, among which, 67.3% reported taking medication daily for asthma. Asthma symptoms were experienced every day by almost 20%, with over 34% of seniors with asthma having symptoms at least once per week. Despite having a lower frequency of asthma symptoms, Hispanics were 5.31 times more likely to visit the ED due to asthma than were Caucasians. CONCLUSIONS: The findings from the study showed that older adults with asthma had difficulty with asthma control. We recommend a focus on asthma education so that when symptoms do occur, options are available to avoid costly ED visits. Further research should focus on specific asthma management skills and adherence to asthma treatment regimen among ethnic groups.

Physical activity and depressive symptoms in older adults.

OBJECTIVES: Depressive symptoms are prevalent in older adults, and physical activity (PA) may have beneficial effects on depression. The purpose of this study was to explore the association between physical activity and depressive symptoms, taking into account demographic factors, and the associations between selected demographic factors and physical activity levels in community-dwelling older adults (age ≥ 60 years). METHODS: Data were drawn from the National Health and Nutrition Examination Survey 2005-2006. Descriptive statistics and logistic models were used in data analysis. RESULTS: Four percent of participants reported moderate depressive symptoms, and 24% of subjects exhibited sedentary PA. Factors associated with increased risk of moderate depression included age, sedentary PA, and chronic medical conditions (ps < 0.05). Sedentary PA was significantly associated with age, race, education, BMI, smoking status, alcohol use, and taking psychotropics (ps < 0.05). DISCUSSION: PA is a protective factor for depression in older adults, and clinical implications to encourage PA are discussed.

Venous thromboembolism knowledge among older post-hip fracture patients and their caregivers.

Patient education about venous thromboembolism (VTE) prevention is needed to prevent complications and costly re-hospitalization. Nurses are uniquely positioned to provide vital education as patients transition from the inpatient setting to after discharge. Still, little is known about patient knowledge deficits and those of their caregivers. The purpose of this study was to explore VTE prevention knowledge in a sample of older hip fracture patients and family caregivers. At the time of hospital discharge, surveys were completed by hip fracture surgery patients (≥65; n=30) and family caregivers (n=30). Participants reported needs for more prophylactic anticoagulation and side effects education. Mean education satisfaction was 3.49 out of 5 among patients and 3.83 among caregivers. Focused patient education regarding the wisdom of VTE prevention, potential risks involved, and patient and caregiver roles in advocating for better prevention measures is needed for these patients at risk for hospital readmission secondary to VTE.
