Family Caregiving of Patients With Heart Failure and Vascular Dementia in Rural Appalachia: A Mixed-Methods Study.

INTRODUCTION: Vascular dementia and heart failure (HF) are common co-existing conditions among adult populations. Each condition requires extensive home caregiving from family caregivers, especially those in rural Appalachia. This study aimed to assess caregivers' burden and their physical and mental health status, as well as explore their experiences and needs. METHODS: This study used an exploratory mixed-methods design combining quantitative and qualitative research (N = 20 caregivers). We collected data using questionnaires, short-answered interviews, and focus group discussions. The multivariable generalized linear model (GLiM) was used to analyze quantitative data; content analysis was used for qualitative data. RESULTS: The average age of family caregivers was 64.95 years. The generalized linear model showed that the caregiving burden was associated with caregivers' depression/anxiety (r = 0.68, P < .001) and their number of dementia caregiving years (r = 0.54, P < .05). Caregivers' poor physical health status was associated with better preparedness for HF and dementia home caregiving (r = 0.52, P < .05) and male caregivers (r = -0.46, P < .01). Caregivers' mental health status was associated with depression/anxiety (r = -0.80, P < .001). The qualitative data identified key caregiving themes: emotional impact and physical demands of caregiving, lack of help in rural areas, dealing with multiple disease progression, and relationship changes with their loved ones. CONCLUSION: Caregiving burden was associated with caregivers' home care responsibilities and the need for support. Nurse-led home caregiving preparedness interventions tailored for family caregivers of patients with HF and dementia in rural areas are recommended.

Responses of Persons Living With Dementia to Caregiver Validating Communication: A Secondary Analysis.

Background and Purpose: Good communication between persons living with dementia and their caregivers is one important consideration when fostering a positive relationship and improving the effectiveness of care. Care can be a challenge if the person living with dementia does not feel understood or fails to cooperate with care. The individual may feel disrespected and may resist assistance. Validation therapy is a person-centered method for communicating with persons living with dementia that involves validating the experiences, feelings, and reality of an individual to encourage cooperation or provide for safety. The purpose of this study was to identify frequencies of four behavioral responses (cooperation, apathy, resistiveness, and distress) from persons living with dementia when validation communication strategies were used during care activities. Methods: This was a secondary analysis of homecare videos (n = 41) of family caregivers interacting with a person living with dementia during daily care. Behavioral coding was used to examine the relationships between validating communication and the response of a person living with dementia. Caregiver use of specific validation techniques in their communication (affirmation, acknowledging emotions, and verbalizing understanding) was coded along with subsequent responses of the person living with dementia (resistiveness, distress, apathy, or cooperation). Results: Affirmations produced an 11% probability of a cooperative response by the person living with dementia. Caregiver verbalization of understanding resulted in a 6% probability of cooperation, and silence was associated with an 8% probability of cooperation. Nonvalidating communication behaviors were associated with negative reactions. Implications for Practice: Effective person-centered communication between caregivers and persons living with dementia improved cooperation with care and decreased distress. Affirmations and verbalizing understanding were two types of validating communication more likely to elicit a cooperative response and can improve care quality, decrease caregiver burnout, and mitigate challenging behavioral responses in persons living with dementia.

Communication Patterns and Characteristics of Family Caregivers and Persons Living With Dementia: Secondary Analysis of Video Observation.

BACKGROUND: It is essential to characterize communication patterns for better health outcomes for family caregivers and persons living with dementia. OBJECTIVE: This study aimed to examine the relationships between communication patterns and the characteristics of dyads of family caregivers and persons living with dementia. METHODS: A secondary analysis was conducted using 75 video-recorded home care observations from 19 dyads. Participant characteristics and caregiver burden, depression, and sense of competence were collected from the parent study. The video-recorded dyadic communication patterns were assessed using a coding scheme developed based on Communication Accommodation Theory and Classical Test Theory. The relative frequency of the communication patterns was compared between groups. RESULTS: Overall, 8311 caregiver and 8024 care recipient communication behaviors were observed. Caregiver communication patterns were categorized as facilitative, disabling, and neutral. Care recipient communication patterns were categorized as engaging, challenging, and neutral. Caregiver gender, care recipient gender, care recipient education level, dementia diagnosis length, types of dementia, dyadic gender difference, burden, depression, and competence of caregiver, and types of communication were significantly associated with caregiver communication. Dementia diagnosis length, caregiver competence, dyadic gender difference, and types of communication were significantly associated with care recipient communication. CONCLUSIONS: The findings demonstrated different communication patterns depending on individual and dyad characteristics and evidence for dyadic communication support to promote meaningful interaction for persons living with dementia. Further analysis is needed to identify mediating factors and causal relationships.

Best practices for communication while wearing facemasks: A scoping review.

INTRODUCTION: Facemasks are an important piece of personal protective equipment (PPE) to mitigate the spread of respiratory illnesses, but they can impede communication between patients and healthcare providers. The purpose of this scoping review is to identify effective communication practices while wearing facemasks. DESIGN: Scoping review using a systematic search of articles from the PubMed, CINAHL, and Embase databases. METHODS: The PEO (population, exposure, outcome) methodology was selected for this systematic scoping review. The population of interest (P) includes humans of all ages (children, adults, and older adults); the exposure of interest (E) is PPE that covers the mouth (i.e., facemasks); and the outcome of interest (O) is successful or unsuccessful communication practices. The Johns Hopkins Evidence-Based Practice for Nurses and Healthcare Professionals appraisal guidelines were used to determine the level and quality of the research. RESULTS: Thirty-nine articles met the inclusion criteria. Seventeen of these were high- or good-quality research studies, and the remaining 22 were non-research articles included with separate analysis as part of the scoping review. The 17 articles encompassed 2656 participants. The highest quality evidence indicated that standard surgical masks have the least impact on speech perception compared to other non-transparent mask types, and that recognizing emotions is less accurate with facemasks, necessitating compensatory actions (i.e., reducing extraneous noise, using a microphone to amplify voice, and employing clear speech). Evidence was contradictory regarding the use of transparent masks. Evidence was of limited quality for other non-verbal and verbal communication strategies. CONCLUSION: Awareness of communication challenges is crucial when wearing facemasks. More high-quality studies are needed to evaluate communication techniques when speakers are wearing facemasks. Basic strategies such as selecting an appropriate mask type, reducing extraneous noise, using microphones, verbalizing emotions, and employing clear speech appear to be beneficial. CLINICAL RELEVANCE: The findings of this scoping review highlight the importance of considering communication challenges while wearing facemasks in the healthcare settings. The review suggests that selecting an appropriate mask type, reducing extraneous noise, verbalizing emotions, and employing clear speech are some strategies that may be effective in mitigating the impact of facemasks on communication between patients and healthcare providers.

A text message intervention to support latino dementia family caregivers (CuidaTEXT): feasibility study.

OBJECTIVES: To test the feasibility, acceptability, and preliminary efficacy of CuidaTEXT: a bidirectional text message intervention to support Latino dementia family caregivers. METHODS: CuidaTEXT is a six-month, bilingual intervention tailored to caregiver needs (e.g., education, problem-solving, resources). We used convenience sampling and reached 31 potential participants via clinics, registries, community promotion, and online advertising. We enrolled 24 Latino caregivers in a one-arm trial and assessed feasibility, acceptability, and preliminary efficacy within six months. RESULTS: None of the participants unsubscribed from CuidaTEXT and 83.3% completed the follow up survey. Most participants (85.7%) reported reading most text messages thoroughly. All participants reported being very or extremely satisfied with the intervention. Participants reported that CuidaTEXT helped a lot (vs not at all, a little, or somehow) in caring for their care recipient (71.4%; n = 15), for themselves (66.7%; n = 14), and understanding more about dementia (85.7%; n = 18). Compared to baseline, at six months caregiver behavioral symptom distress (0-60) decreased from 19.8 to 12.0 and depression (0-30) from 8.8 to 5.4 (p < .05). CONCLUSIONS: CuidaTEXT demonstrated high levels of feasibility, acceptability, and preliminary efficacy among Latino caregivers. CLINICAL IMPLICATIONS: CuidaTEXT's feasibility and potential for widespread implementation holds promise in supporting Latino caregivers of people with dementia.

Beta cell dysfunction induced by bone morphogenetic protein (BMP)-2 is associated with histone modifications and decreased NeuroD1 chromatin binding.

Insufficient insulin secretion is a hallmark of type 2 diabetes and has been attributed to beta cell identity loss characterized by decreased expression of several key beta cell genes. The pro-inflammatory factor BMP-2 is upregulated in islets of Langerhans from individuals with diabetes and acts as an inhibitor of beta cell function and proliferation. Exposure to BMP-2 induces expression of Id1-4, Hes-1, and Hey-1 which are transcriptional regulators associated with loss of differentiation. The aim of this study was to investigate the mechanism by which BMP-2 induces beta cell dysfunction and loss of cell maturity. Mouse islets exposed to BMP-2 for 10 days showed impaired glucose-stimulated insulin secretion and beta cell proliferation. BMP-2-induced beta cell dysfunction was associated with decreased expression of cell maturity and proliferation markers specific to the beta cell such as Ins1, Ucn3, and Ki67 and increased expression of Id1-4, Hes-1, and Hey-1. The top 30 most regulated proteins significantly correlated with corresponding mRNA expression. BMP-2-induced gene expression changes were associated with a predominant reduction in acetylation of H3K27 and a decrease in NeuroD1 chromatin binding activity. These results show that BMP-2 induces loss of beta cell maturity and suggest that remodeling of H3K27ac and decreased NeuroD1 DNA binding activity participate in the effect of BMP-2 on beta cell dysfunction.

Promoting Elderspeak Awareness: Adapting Changing Talk Online Communication Education for Adult Day Services Staff.

Communication is fundamental for dementia care across long-term services and support (LTSS) settings. Education increasing nursing home (NH) staff awareness of person-centered communication has reduced staff elderspeak communication and reduced resistiveness to care of residents with dementia. The current study tested the Changing Talk Online (CHATO) education with adult day services (ADS) staff to identify strategies for adaptation for other LTSS settings. Three dementia-specific ADS sites participated in the CHATO education program. Participants completed knowledge assessment, communication ratings, and confidence ratings on providing care pre- and post-CHATO; a program evaluation; and rated their intention to use skills in practice. Findings were compared to an earlier study of CHATO in NHs. Focus groups evaluated feasibility, applicability, and directions for tailoring. Mean scores on the Changing Talk Scale knowledge test increased by 15 percentage points (p < 0.001). Confidence in providing dementia care scores also increased (p = 0.037). The mean Modified Diffusion of Innovation scale score was 2.2, similar to that in NHs, indicating intent to use skills; and program evaluation was positive. Focus group participants reported CHATO was valuable and recommended incorporating scenarios specific to ADS care. [Research in Gerontological Nursing, 16(2), 85-94.].

Physical Activity and Insulin Sensitivity Independently Attenuate the Effect of FTO rs9939609 on Obesity.

OBJECTIVE: The association between FTO rs9939609 and obesity is modified by physical activity (PA) and/or insulin sensitivity (IS). We aimed to assess whether these modifications are independent, to assess whether PA and/or IS modify the association between rs9939609 and cardiometabolic traits, and to elucidate underlying mechanisms. RESEARCH DESIGN AND METHODS: Genetic association analyses comprised up to 19,585 individuals. PA was self-reported, and IS was defined based on inverted HOMA insulin resistance index. Functional analyses were performed in muscle biopsies from 140 men and in cultured muscle cells. RESULTS: The BMI-increasing effect of the FTO rs9939609 A allele was attenuated by 47% with high PA (ß [SE], -0.32 [0.10] kg/m2, P = 0.0013) and by 51% with high IS (-0.31 [0.09] kg/m2, P = 0.00028). Interestingly, these interactions were essentially independent (PA, -0.20 [0.09] kg/m2, P = 0.023; IS, -0.28 [0.09] kg/m2, P = 0.0011). The rs9939609 A allele was also associated with higher all-cause mortality and certain cardiometabolic outcomes (hazard ratio, 1.07-1.20, P > 0.04), and these effects tended to be weakened by greater PA and IS. Moreover, the rs9939609 A allele was associated with higher expression of FTO in skeletal muscle tissue (0.03 [0.01], P = 0.011), and in skeletal muscle cells, we identified a physical interaction between the FTO promoter and an enhancer region encompassing rs9939609. CONCLUSIONS: Greater PA and IS independently reduced the effect of rs9939609 on obesity. These effects might be mediated through altered expression of FTO in skeletal muscle. Our results indicated that PA and/or other means of increasing insulin sensitivity could counteract FTO-related genetic predisposition to obesity.

Determining Evidence for Family Caregiver Communication: Associating Communication Behaviors With Breakdown and Repair.

BACKGROUND AND OBJECTIVES: Communication is fundamental for dementia care. The trouble source repair (TSR) framework can identify strategies that facilitate or impede communication in dyadic interactions. RESEARCH DESIGN AND METHODS: A secondary analysis of videos (N = 221) from a clinical trial of a family caregiver telehealth intervention was analyzed using sequential behavioral coding of communication behaviors and breakdowns for 53 caregiver and person with dementia dyads. Coded data from 3,642 30-s observations were analyzed using penalized regression for feature selection followed by Bayesian mixed-effects modeling to identify communication strategies associated with communication breakdown and repair. RESULTS: Breakdown (coded as 0) was associated with caregivers changing topic (median = -11.45, 95% credibility interval [CrI; -24.34, -4.37]), ignoring (median = -11.49, 95% CrI [-24.49, -4.72]), giving commands (median = -10.74, 95% CrI [-24.22, -3.38]), and taking over the task (median = -4.06, 95% CrI [-7.28, -1.77]). Successful repair of breakdown was associated with verbalizing understanding (median = 0.46, 95% CrI [0.09, 0.86]), tag questions, (median = 2.4, 95% CrI [0.33, 5.35]), and silence (median = 0.78, 95% CrI [0.42, 1.15]) and negatively associated with ignoring and changing topic (median = -3.63, 95% CrI [-4.81, -2.57] and -2.51 [-3.78, -1.33], respectively). DISCUSSION AND IMPLICATIONS: The TSR was effective in identifying specific communication strategies to avoid (changing topic, ignoring, commands, and taking over the task) and to use to repair breakdown (verbalize understanding, tag questions, and silence). Future research is needed to test these strategies and explore the potential effects of dementia stage, diagnosis, and dyad characteristics in additional samples. Behavioral coding provides evidence of communication best practices as a basis for family caregiver communication training.

Development and psychometric testing of the dyadic communication observational coding scheme in DEmentia care (DCODE): family dyadic communication in dementia.

OBJECTIVES: Understanding family dyadic communication in dementia is essential to promote the well-being of family caregivers and persons living with dementia. The Dyadic Communication Observational coding scheme in DEmentia care (DCODE) was developed and tested to assess family dyadic communication in dementia. METHODS: The DCODE was developed from a review of literature, expert review, and pretesting. A secondary analysis of the 75 in-home care video observations from 19 family caregiver-care recipient dyads was conducted to test psychometric properties. RESULTS: The DCODE consists of 43 caregiver items and 41 care recipient items. We observed internal consistency, intra-rater reliability, and inter-rater reliability as adequate. Content validity and convergent validity were moderate. Predictive validity was moderate in predicting caregiver burden. The overall psychometric properties demonstrated a moderate quality of the DCODE. CONCLUSIONS: Findings provided the preliminary psychometric evidence of the DCODE as a promising instrument to assess family dyadic communication in dementia. Future testing for concurrent, divergent, and structural validity of the DCODE is needed.

Psycholinguistic Assessment of Cognitive Function in Breast Cancer Survivors.

OBJECTIVES: To gather preliminary data on correlations among psycholinguistic measures, self-report of cognitive function, and performance on neurocognitive tests in breast cancer survivors. SAMPLE & SETTING: Participants were breast cancer survivors who reported issues with cognitive function after completion of chemotherapy. This secondary analysis used data from participants in parent studies at two National Cancer Institute-designated cancer centers. METHODS & VARIABLES: Qualitative interview transcripts (N = 52) underwent psycholinguistic analyses for grammatical and semantic complexity. Relationships among six psycholinguistic variables, self-report of cognitive function, and performance on neurocognitive tests were examined. RESULTS: Three grammatical complexity variables had a significant positive correlation to self-report of cognitive function. One semantic complexity variable had a significant positive correlation to delayed recall neurocognitive tests. IMPLICATIONS FOR NURSING: Results suggest that psycholinguistic analysis may be used to assess cognitive function among breast cancer survivors. Confirmatory studies are needed to establish the correlation between psycholinguistic measures, self-report of cognitive function, and domain-specific tests of neurocognitive performance, as well as to evaluate longitudinal sensitivity to change.

Developing and Testing Remote Implementation for the Changing Talk Online (CHATO) Communication Intervention for Nursing Home Staff: A Pilot Pragmatic Randomized Controlled Trial.

Background and Objectives: The Changing Talk (CHAT) communication training effectively reduces elderspeak and subsequent behavioral challenges in residents with dementia in nursing homes (NHs). As part of the pilot pragmatic clinical trial testing Changing Talk: Online Training (CHATO), a new online version, a remote implementation design, and process evaluation were developed to capture contextual factors, ensure fidelity, and determine effective implementation strategies. Research Design and Methods: The Expert Recommendation for Implementing Change compilation informed this 2-phase approach to develop and test remote implementation. An Advisory Board guided the developmental phase while pilot testing used a cluster-randomized design. Data were analyzed to evaluate NH characteristics; implementation strategies used; CHATO participation, completion, and passing rates; and leadership evaluation. Results: Five out of 7 NHs were nonprofit with above average quality ratings (M = 4.3 of 5). Staff participants (N = 237) were mostly female (90%), non-Hispanic White (91%), and nursing assistants (46%). Implementation time ranged from 54 to 86 days (M = 70.3, standard deviation [SD] = 9.3), with planning phase ranging from 11 to 29 days (M = 20.1, SD = 6.7), and training phase ranging from 35 to 58 days (M = 50.0, SD = 7.6). A range from 3 to 11 implementation strategies were used by each NH. Assigning champions, including the social worker on the implementation team, utilizing multiple mediums for reminders, giving rewards or public recognition, supporting onsite discussions, and other tailoring strategies were associated with improved outcomes. Participation ranged from 20% to 76%. Over 63% of participants completed training (N = 150) and 87% passed the posttest (N = 130). Leadership evaluations noted staff used CHATO concepts in practice and improved communication culture. Discussion and Implications: Leadership who took an active role, engaged multiple team members, and varied strategies had better outcomes. Effectiveness of the strategies will be evaluated in a national pragmatic clinical trial testing CHATO's effects on reducing behavioral and psychological symptoms in dementia care.

Butyrate inhibits IL-1ß-induced inflammatory gene expression by suppression of NF-κB activity in pancreatic beta cells.

Cytokine-induced beta cell dysfunction is a hallmark of type 2 diabetes (T2D). Chronic exposure of beta cells to inflammatory cytokines affects gene expression and impairs insulin secretion. Thus, identification of anti-inflammatory factors that preserve beta cell function represents an opportunity to prevent or treat T2D. Butyrate is a gut microbial metabolite with anti-inflammatory properties for which we recently showed a role in preventing interleukin-1ß (IL-1ß)-induced beta cell dysfunction, but how prevention is accomplished is unclear. Here, we investigated the mechanisms by which butyrate exerts anti-inflammatory activity in beta cells. We exposed mouse islets and INS-1E cells to a low dose of IL-1ß and/or butyrate and measured expression of inflammatory genes and nitric oxide (NO) production. Additionally, we explored the molecular mechanisms underlying butyrate activity by dissecting the activation of the nuclear factor-κB (NF-κB) pathway. We found that butyrate suppressed IL-1ß-induced expression of inflammatory genes, such as Nos2, Cxcl1, and Ptgs2, and reduced NO production. Butyrate did not inhibit IκBα degradation nor NF-κB p65 nuclear translocation. Furthermore, butyrate did not affect binding of NF-κB p65 to target sequences in synthetic DNA but inhibited NF-κB p65 binding and RNA polymerase II recruitment to inflammatory gene promoters in the context of native DNA. We found this was concurrent with increased acetylation of NF-κB p65 and histone H4, suggesting butyrate affects NF-κB activity via inhibition of histone deacetylases. Together, our results show butyrate inhibits IL-1ß-induced inflammatory gene expression and NO production through suppression of NF-κB activation and thereby possibly preserves beta cell function.

Elderspeak communication and pain severity as modifiable factors to rejection of care in hospital dementia care.

BACKGROUND: Rejection of care (RoC) occurs when persons living with dementia (PLWD) withstand or oppose the efforts of their caregiver. Improvements in hospital dementia care are needed, and one way to address this need is by identifying factors that lead to RoC, particularly those that are modifiable. Elderspeak communication is an established antecedent to RoC among PLWD in nursing homes. The purpose of this study was to extend these results to acute care settings by determining the impact of elderspeak communication by nursing staff on RoC by hospitalized PLWD. METHODS: Care encounters between nursing staff and PLWD were audio-recorded, transcribed verbatim, and coded for semantic, pragmatic, and prosodic features of elderspeak. RoC behaviors was scored in real-time using the Resistiveness to Care Scale. A Bayesian repeated-measures hurdle model was used to evaluate the association between elderspeak and both the presence and severity of RoC. RESULTS: Eighty-eight care encounters between 16 PLWD and 53 nursing staff were audio-recorded for elderspeak and scored for RoC. Nearly all (96.6%) of the encounters included some form of elderspeak. Almost half of the care encounters (48.9%) included RoC behaviors. A 10% decrease in elderspeak was associated with a 77% decrease in odds of RoC (OR = 0.23, 95% CI = 0.03, 0.68) and a 16% decrease ( e ß =  0.84, CI = 0.73, 0.96) in the severity of RoC. A one-unit decrease in pain severity was associated with 73% reduced odds of RoC (OR = 0.27, CI = 0.12, 0.45) and a 28% decrease ( e ß =  0.72, CI = 0.64, 0.80) in the severity of RoC. CONCLUSIONS: Both elderspeak by nursing staff and RoC by PLWD are present and pervasive in acute care. Pain and elderspeak are two modifiable factors of RoC in hospitalized PLWD. Person-centered interventions are needed that address communication practices and pain management for hospitalized PLWD.

Characteristics of elderspeak communication in hospital dementia care: Findings from The Nurse Talk observational study.

BACKGROUND: Elderspeak communication is typically viewed as patronizing and infantilizing by older adults and can lead to resistive behaviors in persons living with dementia. Little is known about the presence of elderspeak communication in hospitals in the United States. Understanding this phenomenon in the hospital setting is needed in order to improve hospital dementia care. OBJECTIVES: The purpose of the Nurse Talk study was to (1) describe attributes of elderspeak use in hospital dementia care and to (2) determine what characteristics are associated with nursing staff use of elderspeak communication with hospitalized patients with dementia. DESIGN: A cross-sectional observational study design was used to collect and analyze audio-recordings of nursing staff during care for hospitalized patients with dementia. SETTING: Three hospital units in one Midwestern university hospital in the United States. PARTICIPANTS: A convenience sample of 53 staff nurses and nursing assistants that provided direct care to 16 patients with mild or more severe dementia recruited from October 2019 through mid-March 2020. METHODS: Eighty-eight care encounters were audio-recorded and coded for elderspeak communication using the Iowa Coding of Elderspeak scheme to determine the frequency and characteristics of elderspeak communication. A linear mixed effects model was used to determine what characteristics were associated with elderspeak and the frequency of elderspeak use by nursing staff to hospitalized patients with dementia. RESULTS: Over a quarter (28.7%) of all nursing staff speech directed towards patients with dementia constituted elderspeak and nearly all (96.6%) care encounters included some elderspeak. Particularly common attributes of elderspeak were minimizing words and mitigating expressions, childish terms and phrases, and collective pronoun substitution. A statistically significant interaction was identified between staff role and age (95% CI: -0.02, -0.00, p = .008) in predicting the frequency of elderspeak use, indicating that elderspeak was used more often by older staff nurses, whereas the age of nursing assistants remained constant across elderspeak use. Statically significant effects for delirium and length of stay were also demonstrated. Elderspeak use was 12.5% higher with patients with delirium (95% CI: 0.02, 0.23, p = .025) and increased 1.5% for each additional day the patient with dementia was hospitalized (95% CI: 0.00, 0.03, p = .035). CONCLUSIONS: Elderspeak is present and pervasive in the acute care setting. Interventions targeted towards older staff nurses and nursing staff from hospital units that care for patients with delirium and longer lengths of stay are needed. TWEETABLE ABSTRACT: This study identified that nursing staff are frequently using elderspeak (infantilizing speech) with hospitalized patients with dementia. @claireshaw_phd @IowaNursing.

A Text Messaging Intervention to Support Latinx Family Caregivers of Individuals With Dementia (CuidaTEXT): Development and Usability Study.

BACKGROUND: Latinx family caregivers of individuals with dementia face many barriers to caregiver support access. Interventions to alleviate these barriers are urgently needed. OBJECTIVE: This study aimed to describe the development of CuidaTEXT, a tailored SMS text messaging intervention to support Latinx family caregivers of individuals with dementia. METHODS: CuidaTEXT is informed by the stress process framework and social cognitive theory. We developed and refined CuidaTEXT using a mixed methods approach that included thematic analysis and descriptive statistics. We followed 6 user-centered design stages, namely, the selection of design principles, software vendor collaboration, evidence-based foundation, caregiver and research and clinical advisory board guidance, sketching and prototyping, and usability testing of the prototype of CuidaTEXT among 5 Latinx caregivers. RESULTS: CuidaTEXT is a bilingual 6-month-long SMS text messaging-based intervention tailored to caregiver needs that includes 1-3 daily automatic messages (n=244) about logistics, dementia education, self-care, social support, end of life, care of the person with dementia, behavioral symptoms, and problem-solving strategies; 783 keyword-driven text messages for further help with the aforementioned topics; live chat interaction with a coach for further help; and a 19-page reference booklet summarizing the purpose and functions of the intervention. The 5 Latinx caregivers who used the prototype of CuidaTEXT scored an average of 97 out of 100 on the System Usability Scale. CONCLUSIONS: CuidaTEXT's prototype demonstrated high usability among Latinx caregivers. CuidaTEXT's feasibility is ready to be tested.

Mealtime nonverbal behaviors in nursing home staff and residents with dementia: Behavioral analyses of videotaped observations.

This study characterized mealtime nonverbal behaviors of nursing home staff and residents with dementia and examined the relationships between individual characteristics and nonverbal behaviors. Videotaped observations (N=110) involving 25 residents and 29 staff (42 unique staff-resident dyads) in 9 nursing homes were coded using the refined Cue Utilization and Engagement in Dementia Mealtime Video-Coding Scheme. Wilcoxon rank-sum test or Kruskal-Wallis test were used for continuous characteristics, and Fisher's exact test for categorical characteristics. Residents primarily exhibited challenging behaviors including resistive behaviors (35.7%), chewing/swallowing difficulties (33.5%), and functional impairments (9.9%), followed by positive/neutral behaviors (20.9%). Staff primarily used person-centered behavioral strategies, including modifications of: 1) resident abilities (41.9%), 2) care approaches (35.1%), and 3) dining environment (13.6%), followed by task-centered behaviors (9.3%). Residents challenging behaviors were correlated with staff person-centered behavioral strategies. Dyadic nonverbal behaviors were correlated with multiple individual characteristics. Understanding dyadic nonverbal interactions facilitates use of person-centered, multilevel, behavioral strategies to optimize mealtime outcomes.

Developing Behavioral Coding to Understand Family Communication Breakdown in Dementia Care.

Communication breakdown is a challenge for family caregivers of persons living with dementia. We adapted established theory and scales for computer-assisted behavioral coding to characterize caregiver communication for a secondary analysis. We developed verbal, nonverbal, and breakdown coding schemes and established reliability (κ > .85). Within the 221 family caregiving videos analyzed, 55% of exchanges were interactive, 30% were silence, 4% consisted of talking to self or others, and 8% included a breakdown. An average of 2.4 (SD = 1.9) breakdowns occurred per observation and were successfully resolved 85% of the time, with 31% being resolved most successfully following only one flag and repair strategy. Caregivers were the primary speakers (67%); their communication preceded most breakdown (65%), and they primarily initiated the repairs after a breakdown (70%). Common repair strategies included clarifications (31%), asking questions (24%), and repeating information (24%). Associations between communication strategies and repair success will provide evidence for caregiver training.

The exercise-induced long noncoding RNA CYTOR promotes fast-twitch myogenesis in aging.

Skeletal muscle displays remarkable plasticity upon exercise and is also one of the organs most affected by aging. Despite robust evidence that aging is associated with loss of fast-twitch (type II) muscle fibers, the underlying mechanisms remain to be elucidated. Here, we identified an exercise-induced long noncoding RNA, CYTOR, whose exercise responsiveness was conserved in human and rodents. Cytor overexpression in mouse myogenic progenitor cells enhanced myogenic differentiation by promoting fast-twitch cell fate, whereas Cytor knockdown deteriorated expression of mature type II myotubes. Skeletal muscle Cytor expression was reduced upon mouse aging, and Cytor expression in young mice was required to maintain proper muscle morphology and function. In aged mice, rescuing endogenous Cytor expression using adeno-associated virus serotype 9 delivery of CRISPRa reversed the age-related decrease in type II fibers and improved muscle mass and function. In humans, CYTOR expression correlated with type II isoform expression and was decreased in aged myoblasts. Increased CYTOR expression, mediated by a causal cis­expression quantitative trait locus located within a CYTOR skeletal muscle enhancer element, was associated with improved 6-min walk performance in aged individuals from the Helsinki Birth Cohort Study. Direct CYTOR overexpression using CRISPRa in aged human donor myoblasts enhanced expression of type II myosin isoforms. Mechanistically, Cytor reduced chromatin accessibility and occupancy at binding motifs of the transcription factor Tead1 by binding, and hence sequestering, Tead1. In conclusion, the long noncoding RNA Cytor was found to be a regulator of fast-twitch myogenesis in aging.

Changing Talk Online: Protocol for a cluster pragmatic trial testing communication education to reduce behavioral and psychological symptoms of dementia in nursing home care.

Nursing home (NH) care of persons living with dementia is often made challenging by behavioral and psychological symptoms of dementia (BPSD) such as aggression, vocal outbursts, wandering, and withdrawal that occur due to cognitive and communication changes. Staff frequently communicate to NH residents using "elderspeak" which is patronizing speech similar to baby talk. Residents respond to elderspeak with increased BPSD that prompts use of psychotropic medication to control symptoms. The Changing Talk (CHAT) training educates staff about effective, person-centered communication strategies and reduces elderspeak by staff and subsequent BPSD among residents. This study will test effects of an adapted online version (CHATO) increasing access and dissemination of education to busy staff across diverse care settings. Nursing homes (N = 128) will be stratified and then randomized to CHATO education (n = 64) or to the control group (n = 64). Data on behavioral symptoms (primary outcomes) and psychotropic medication use (secondary outcomes) will be extracted from the Center for Medicare and Medicaid Services Minimum Data Set before and after education and will be compared between the groups using generalized linear mixed modeling. It is hypothesized that after completing the CHATO education residents will have reduced behavioral symptoms and psychotropic medication use compared to residents in control NHs. Additionally, factors related to NH participation and cost of the intervention will be determined. The overall goal of this study is to prepare for large scale dissemination and implementation of the evidence-based nonpharmacological CHATO intervention to reduce BPSD in residents with dementia across long-term care settings.
