Food insecurity in urban American Indian and Alaska Native populations during the COVID-19 pandemic.

BACKGROUND: Food insecurity is an important social determinant of health that was exacerbated by the COVID-19 pandemic. Both food insecurity and COVID-19 infection disproportionately affect racial and ethnic minority groups, particularly American Indian and Alaska Native communities; however, there is little evidence as to whether food insecurity is associated with COVID-19 infection or COVID-19 preventive behaviors such as vaccination uptake. The purpose of this study was to evaluate associations between food insecurity, COVID-19 infection, and vaccination status among urban American Indian and Alaska Native adults seen at 5 clinics serving urban Native people. METHODS: In partnership with health organizations in Alaska, Colorado, Kansas, Minnesota, and New Mexico, the study team conducted a cross-sectional survey in 2021 to assess food security status and attitudes, barriers, and facilitators for COVID-19 testing and vaccination. Logistic regression was used to examine the association of food security status with sociodemographic factors and COVID-19 infection and vaccination status. Marginal standardization was applied to present results as prevalence differences. RESULTS: Among 730 American Indian and Alaska Native adults, the prevalence of food insecurity measured during the pandemic was 38%. For participants who reported persistent food security status before and during the pandemic (n = 588), the prevalence of food insecurity was 25%. Prevalence of COVID-19 infection and vaccination did not vary by food security status after adjustment for confounders. CONCLUSIONS: High rates of food insecurity among American Indian and Alaska Native communities likely increased during the COVID-19 pandemic. However, despite the high prevalence of food insecurity, community-led efforts to reduce COVID-19 infection and increase vaccination uptake across Indian Health Service and Tribal healthcare facilities may have mitigated the negative impacts of the pandemic for families experiencing food insecurity. These successful approaches serve as an important reference for future public health efforts that require innovative strategies to improve overall health in American Indian and Alaska Native communities.

Reliability and validity of the revised Rushton Moral Resilience Scale for healthcare workers.

AIM: To refine the Rushton Moral Resilience Scale (RMRS) by creating a more concise scale, improving the reliability, particularly of the personal integrity subscale and providing further evidence of validity. BACKGROUND: Healthcare workers are exposed to moral adversity in practice. When unable to preserve/restore their integrity, moral suffering ensues. Moral resilience is a resource that may mitigate negative consequences. To better understand mechanisms for doing so, a valid and reliable measurement tool is necessary. DESIGN: Cross-sectional survey. METHODS: Participants (N = 1297) had completed ≥1 items on the RMRS as part of the baseline survey of a larger longitudinal study. Item analysis, confirmatory factor analyses, reliability analyses (Cronbach's alpha), and correlations were used to establish reliability and validity of the revised RMRS. RESULTS: Item and confirmatory factor analysis were used to refine the RMRS from 21 to 16 items. The four-factor structure (responses to moral adversity, personal integrity, relational integrity and moral efficacy) demonstrated adequate fit in follow-up confirmatory analyses in the initial and hold-out sub-samples. All subscales and the total scale had adequate reliabilities (α ≥ 0.70). A higher-order factor analysis supports the computation of either subscale scores or a total scale score. Correlations of scores with stress, anxiety, depression and moral distress provide evidence of the scale's validity. Reliability of the personal integrity subscale improved. CONCLUSION AND IMPLICATIONS: The RMRS-16 demonstrates adequate reliability and validity, particularly the personal integrity subscale. Moral resilience is an important lever for reducing consequences when confronted with ethical challenges in practice. Improved reliability of the four subscales and having a shorter overall scale allow for targeted application and will facilitate further research and intervention development. PATIENT/PUBLIC CONTRIBUTION: Data came from a larger study of Canadian healthcare workers from multiple healthcare organizations who completed a survey about their experiences during COVID-19.

Living with multimorbidity: A qualitative exploration of shared experiences of patients, family caregivers, and healthcare professionals in managing symptoms in the United States.

AIMS: To elicit experiences of patients, family caregivers, and healthcare professionals in intermediate care units (IMCUs) in an academic medical centre in Baltimore, MD related to the challenges and intricacies of multimorbidity management to inform development of a multimorbidity symptom management toolkit. DESIGN: Experience-based co-design. METHODS: Between July and October 2021, patients aged 55 years and older with multimorbidity admitted to IMCUs at an academic medical centre in Baltimore, Maryland, USA were recruited and interviewed in person. Interdisciplinary healthcare professionals working in the IMCU were interviewed virtually. Participants were asked questions about their role in recognizing and treating symptoms, factors affecting the quality of life, symptom burden and trajectory over time, and strategies that have and have not worked for managing symptoms. An inductive thematic analysis approach was used for analysis. RESULTS: Twenty-three interviews were conducted: 9 patients, 2 family caregivers, and 12 healthcare professionals. Patients' mean age was 67.5 (±6.5) years, over half (n = 5) were Black or Hispanic, and the average number of comorbidities was 3.67. Five major themes that affect symptom management emerged: (1) the patient-provider relationship; (2) open and honest communication; (3) accessibility of resources during hospitalization and at discharge; (4) caregiver support, training, and education; and (5) care coordination and follow-up care. CONCLUSION: Patients, caregivers, and healthcare professionals often have similar goals but different priorities for multimorbidity management. It is imperative to identify shared priorities and target holistic interventions that consider patient and caregiver experiences to improve outcomes. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE AND IMPACT: This paper addresses the paucity of research related to the shared experience of disease trajectory and symptom management for people living with multimorbidity. We found that patients, caregivers, and healthcare professionals often have similar goals but different care and communication priorities. Understanding differing priorities will help better design interventions to support symptom management so people with multimorbidity can have the best possible quality of life. REPORTING METHOD: We have adhered to the Consolidated Criteria for Reporting Qualitative Studies (COREQ) guidelines in our reporting. PATIENT OR PUBLIC CONTRIBUTION: This study has been designed and implemented with patient and public involvement throughout the process, including community advisory board engagement in the project proposal phase and interview guide development, and member checking in the data collection and analysis phases. The method we chose, experience-based co-design, emphasizes the importance of engaging members of a community to act as experts in their own life challenges. In the coming phases of the study, the public will be involved in developing and testing a new intervention, informed by these qualitative interviews and co-design events, to support symptom management for people with multimorbidity.

Cultural Protection from Polysubstance Use Among Native American Adolescents and Young Adults.

Reservation-based Native American youth are at disproportionate risk for high-risk substance use. The culture-as-treatment hypothesis suggests aspects of tribal culture can support prevention and healing in this context; however, the protective role of communal mastery and tribal identity have yet to be fully explored. The objectives of this study were to investigate (1) the relationship between cultural factors and high-risk substance use, which includes polysubstance use, early initiation of alcohol and illicit drugs, and binge drinking, and (2) substance use frequency and prevalence of various substances via cross-sectional design. Multiple logistic regression modeling was used to analyze data from 288 tribal members (15-24 years of age) residing on/near the Fort Peck Reservation in the Northern Plains. When controlling for childhood trauma and school attendance, having at least a high school education (OR = 0.434, p = 0.028), increased communal mastery (OR = 0.931, p = 0.007), and higher levels of tribal identity (OR = 0.579, p = 0.009) were significantly associated with lower odds of polysubstance use. Overall prevalence of polysubstance use was 50%, and binge drinking had the highest single substance prevalence (66%). Prevalence of early initiation of substances (≤ 14 years) was inhalants (70%), alcohol (61%), marijuana (74%), methamphetamine (23%), and prescription drug misuse (23%). Hydrocodone, an opioid, was the most frequently misused prescription drug. Findings indicate programs focused on promoting education engagement, communal mastery, and tribal identity may mitigate substance use for Native American adolescents living in high-risk, reservation-based settings.

Organizational Impact on Healthcare Workers' Moral Injury During COVID-19: A Mixed-Methods Analysis.

OBJECTIVE: The aim of this study was to explore relationships between organizational factors and moral injury among healthcare workers and the impact of perceptions of their leaders and organizations during COVID-19. BACKGROUND: COVID-19 placed healthcare workers at risk for moral injury, which often involves feeling betrayed by people with authority and can impact workplace culture. METHODS: Secondary data from a Web-based survey of mid-Atlantic healthcare workers were analyzed using mixed methods. Data were synthesized using the Reina Trust & Betrayal Model. RESULTS: Fifty-five percent (n = 328/595) of respondents wrote comments. Forty-one percent (n = 134/328) of commenters had moral injury scores of 36 or higher. Three themes emerged: organizational infrastructure, support from leaders, and palliative care involvement. Respondents outlined organizational remedies, which were organized into 5 domains. CONCLUSIONS: Findings suggest healthcare workers feel trust was breached by their organizations' leaders during COVID-19. Further study is needed to understand intersections between organizational factors and moral injury to enhance trust within healthcare organizations.

Burnout and moral resilience in interdisciplinary healthcare professionals.

AIMS AND OBJECTIVES: To examine demographic and work characteristics of interdisciplinary healthcare professionals associated with higher burnout and to examine whether the four domains of moral resilience contribute to burnout over and above work and demographic variables. BACKGROUND: Healthcare professionals experience complex ethical challenges on a daily basis leading to burnout and moral distress. Measurement of moral resilience is a new and vital step in creating tailored interventions that will foster moral resilience at the bedside. DESIGN: Cross-sectional descriptive design. METHODS: Healthcare professionals in the eastern USA were recruited weekly via email for 3 weeks in this cross-sectional study. Online questionnaires were used to conduct the study. The STROBE checklist was used to report the results. RESULTS: Work and demographic factors, such as religious preference, years worked in a healthcare profession, practice location, race, patient age, profession and education level, have unique relationships with burnout subscales and turnover intention, with the four subscales of moral resilience demonstrating a protective relationship with outcomes above and beyond the variance explained by work and demographic characteristics. CONCLUSIONS: Higher moral resilience is related to lower burnout and turnover intentions, with multiple work demographic correlates allowing for potential areas of intervention to deal with an increase in morally distressing situations occurring at the bedside. Additionally, patterns of significant and non-significant relationships between the moral resilience subscales and burnout subscales indicate that these subscales represent unique constructs. RELEVANCE TO CLINICAL PRACTICE: Understanding the everyday, pre-pandemic correlations of moral resilience and burnout among interdisciplinary clinicians allows us to see changes that may exist. Measuring and understanding moral resilience in healthcare professionals is vital for creating ways to build healthier, more sustainable clinical work environments and enhanced patient care delivery.

Wakȟáŋyeza (Little Holy One) - an intergenerational intervention for Native American parents and children: a protocol for a randomized controlled trial with embedded single-case experimental design.

BACKGROUND: Trauma within Native American communities compromises parents' parenting capacity; thus, increasing childrens' risk for substance use and suicide over the lifespan. The objective of this manuscript is to describe the Wakȟáŋyeza (Little Holy One) intervention and evaluation protocol, that is designed to break cycles of intergenerational trauma, suicide, and substance use among Fort Peck Assiniboine and Sioux parents and their children. METHODS: A randomized controlled trial with an embedded single-case experimental design will be used to determine effectiveness of the modular prevention intervention on parent-child outcomes and the added impact of unique cultural lesson-components. Participants include 1) Fort Peck Assiniboine and Sioux parents who have had adverse childhood experiences, and 2) their children (3-5 years). Parent-child dyads are randomized (1:1) to Little Holy One or a control group that consists of 12 lessons taught by Indigenous community health workers. Lessons were developed from elements of 1) the Common Elements Treatment Approach and Family Spirit, both evidence-based interventions, and 2) newly created cultural (intervention) and nutrition (control group only) lessons. Primary outcomes are parent (primary caregiver) trauma symptoms and stress. Secondary outcomes include: Parent depression symptoms, parenting practices, parental control, family routines, substance use, historical loss, communal mastery, tribal identity, historical trauma. Child outcomes include, externalizing and internalizing behavior and school attendance. Primary analysis will follow an intent-to-treat approach, and secondary analysis will include examination of change trajectories to determine impact of cultural lessons and exploration of overall effect moderation by age and gender of child and type of caregiver (e.g., parent, grandparent). DISCUSSION: Many Native American parents have endured adverse childhood experiences and traumas that can negatively impact capacity for positive parenting. Study results will provide insights about the potential of a culturally-based intervention to reduce parental distress - an upstream approach to reducing risk for childrens' later substance misuse and suicidality. Intervention design features, including use of community health workers, cultural grounding, and administration in Head Start settings lend potential for feasibility, acceptability, sustainability, and scalability.

Responses to a Social Media Campaign Promoting Safe Fish Consumption Among Women.

We used a framework to systematically evaluate which Facebook advertisements promoting safe fish consumption increased traffic to our website. Keeping images and headlines constant, we tested 11 message types in 5 categories between 2 audiences over a 24-hour weekday period. We identified clear preferences in 9 of 10 comparisons and evidence to suggest that more women prefer presentation of question format compared with narratives, marketing compared with patient education copy, and uncertain compared with certain copy. Our test of messages on a social media platform is a quick and inexpensive way to select the most engaging public health messages for broad dissemination.

Sociodemographic Factors Associated with Types of Projects Implemented by Volunteer Lay Health Educators in Their Congregations.

This study focused on the association between type of community health interventions and lay health educator variables. Lay health educators are volunteers from local faith communities who complete a healthcare training program, taught by physicians in-training. Lay health educators are instructed to implement health-related initiatives in their respective communities after graduation. Of the 72 graduates since 2011, we surveyed 55 lay health educators to gain insight into their involvement with their congregation and the type of health projects they have implemented. We dichotomized the health projects into "raising awareness" and "teaching new health skills." Using adjusted logistic regression models, variables associated with implementing health projects aimed at teaching health skills included length of time as a member of their congregation, current employment, and age. These results may help future programs prepare lay health community educators for the type of health interventions they intend to implement in their respective communities.

Caring for the Caregiver: Identifying the Needs of Those Called to Care Through Partnerships with Congregations.

As the older adult population continues to grow, the prevalence of chronic diseases is also increasing, leading to the need for novel ways of managing this large population of patients. One solution is to focus on informal caregivers. These informal caregivers already make a substantial contribution to our nation's healthcare finances and patient health outcomes. Caregivers also derive benefits from caring for their family member or friend; however, it is not uncommon for these individuals to experience negative health consequences, or what is often called "burden of care." Those called to care are not without their own burdens, and they must frequently make significant lifestyle adjustments that impact their own health. Therefore, for caregivers to be effective, caring for the caregivers must be a focus of medicine in the twenty-first century.

The lineage-specific gene ponzr1 is essential for zebrafish pronephric and pharyngeal arch development.

The Homeobox (Hox) and Paired box (Pax) gene families are key determinants of animal body plans and organ structure. In particular, they function within regulatory networks that control organogenesis. How these conserved genes elicit differences in organ form and function in response to evolutionary pressures is incompletely understood. We molecularly and functionally characterized one member of an evolutionarily dynamic gene family, plac8 onzin related protein 1 (ponzr1), in the zebrafish. ponzr1 mRNA is expressed early in the developing kidney and pharyngeal arches. Using ponzr1-targeting morpholinos, we show that ponzr1 is required for formation of the glomerulus. Loss of ponzr1 results in a nonfunctional glomerulus but retention of a functional pronephros, an arrangement similar to the aglomerular kidneys found in a subset of marine fish. ponzr1 is integrated into the pax2a pathway, with ponzr1 expression requiring pax2a gene function, and proper pax2a expression requiring normal ponzr1 expression. In addition to pronephric function, ponzr1 is required for pharyngeal arch formation. We functionally demonstrate that ponzr1 can act as a transcription factor or co-factor, providing the first molecular mode of action for this newly described gene family. Together, this work provides experimental evidence of an additional mechanism that incorporates evolutionarily dynamic, lineage-specific gene families into conserved regulatory gene networks to create functional organ diversity.

A two years longitudinal study of a transgenic Huntington disease monkey.

BACKGROUND: A two-year longitudinal study composed of morphometric MRI measures and cognitive behavioral evaluation was performed on a transgenic Huntington's disease (HD) monkey. rHD1, a transgenic HD monkey expressing exon 1 of the human gene encoding huntingtin (HTT) with 29 CAG repeats regulated by a human polyubiquitin C promoter was used together with four age-matched wild-type control monkeys. This is the first study on a primate model of human HD based on longitudinal clinical measurements. RESULTS: Changes in striatal and hippocampal volumes in rHD1 were observed with progressive impairment in motor functions and cognitive decline, including deficits in learning stimulus-reward associations, recognition memory and spatial memory. The results demonstrate a progressive cognitive decline and morphometric changes in the striatum and hippocampus in a transgenic HD monkey. CONCLUSIONS: This is the first study on a primate model of human HD based on longitudinal clinical measurements. While this study is based a single HD monkey, an ongoing longitudinal study with additional HD monkeys will be important for the confirmation of our findings. A nonhuman primate model of HD could complement other animal models of HD to better understand the pathogenesis of HD and future development of diagnostics and therapeutics through longitudinal assessment.

The use and significance of a research networking system.

BACKGROUND: Universities have begun deploying public Internet systems that allow for easy search of their experts, expertise, and intellectual networks. Deployed first in biomedical schools but now being implemented more broadly, the initial motivator of these research networking systems was to enable easier identification of collaborators and enable the development of teams for research. OBJECTIVE: The intent of the study was to provide the first description of the usage of an institutional research "social networking" system or research networking system (RNS). METHODS: Number of visits, visitor location and type, referral source, depth of visit, search terms, and click paths were derived from 2.5 years of Web analytics data. Feedback from a pop-up survey presented to users over 15 months was summarized. RESULTS: RNSs automatically generate and display profiles and networks of researchers. Within 2.5 years, the RNS at the University of California, San Francisco (UCSF) achieved one-seventh of the monthly visit rate of the main longstanding university website, with an increasing trend. Visitors came from diverse locations beyond the institution. Close to 75% (74.78%, 208,304/278,570) came via a public search engine and 84.0% (210 out of a sample of 250) of these queried an individual's name that took them directly to the relevant profile page. In addition, 20.90% (214 of 1024) visits went beyond the page related to a person of interest to explore related researchers and topics through the novel and networked information provided by the tool. At the end of the period analyzed, more than 2000 visits per month traversed 5 or more links into related people and topics. One-third of visits came from returning visitors who were significantly more likely to continue to explore networked people and topics (P<.001). Responses to an online survey suggest a broad range of benefits of using the RNS in supporting the research and clinical mission. CONCLUSIONS: Returning visitors in an ever-increasing pool of visitors to an RNS are among those that display behavior consistent with using the tool to identify new collaborators or research topics. Through direct user feedback we know that some visits do result in research-enhancing outcomes, although we cannot address the scale of impact. With the rapid pace of acquiring visitors searching for individual names, the RNS is evolving into a new kind of gateway for the university.

Early adolescent development in the face of violence: A systematic review running.

BACKGROUND: Exposure to violence has severe and lasting effects on development. Despite the body of research examining childhood exposures to violence and victimization, developmental outcomes during early adolescence are poorly understood. OBJECTIVE: To synthesize existing research on the effects of violence exposure on early adolescent development (youth 9-14 years old) and highlight areas for future research. METHOD: We conducted a systematic search of PubMed, CINAHL, Web of Science, Scopus, and EMBASE for articles published between 2012 and 2023. Included articles focused on violence exposure related to experiencing or observing community violence, witnessing domestic violence and/or being the victim of chronic physical abuse. RESULTS: Twenty-eight articles spanning four developmental domains were included: behavioral, biological, neurological, and social development. Behaviorally, violence exposure posed significant effects on both internalizing and externalizing symptoms. Biologically, violence exposure was strongly associated with advanced epigenetic age, accelerated puberty, and insomnia. Neurologically, violence exposure had significant associations with both structural and functional differences in the developing brain. Socially, violence exposure was related to poor school engagement, peer aggression, and low social support. CONCLUSION: This systematic review highlights varying effects of violence exposure on early adolescent development. The gaps presented should be addressed and implemented into clinical practice via evidence-based policies and procedures to ensure successful transition to adulthood.

Palliative Care Research and Clinical Practice Priorities in the United States as Identified by an Interdisciplinary Modified Delphi Approach.

Background: Palliative care demands in the United States are growing amid a comparatively small workforce of palliative care clinicians and researchers. Therefore, determining research and clinical practice priorities is essential for streamlining initiatives to advance palliative care science and practice. Objectives: To identify and rank palliative care research and clinical practice priority areas through expert consensus. Design: Using a modified Delphi method, U.S. palliative care experts identified and ranked priority areas in palliative care research and clinical practice. Priorities were thematically grouped and analyzed for topic content and frequency; univariate analysis used the median of each priority item ranking, with a cutoff median of ≤8 indicating >76% agreement for an item's ranking. Results: In total, 27 interdisciplinary pediatric and adult palliative care experts representing 19 different academic institutions and medical centers participated in the preliminary survey and the first Delphi round, and 22 participated in the second Delphi round. The preliminary survey generated 78 initial topics, which were developed into 22 priority areas during the consensus meeting. The top five priorities were (1) access to palliative care, (2) equity in palliative care, (3) adequate financing of palliative care, (4) provision of palliative care in primary care settings, and (5) palliative care workforce challenges. Conclusions: These expert-identified priority areas provide guidance for researchers and practitioners to develop innovative models, policies, and interventions, thereby enriching the quality of life for those requiring palliative care services.

Recruitment, Retention and Intervention Delivery Experiences With Hospice Family Caregivers.

BACKGROUND: Recruitment and attrition are inherently challenging issues in hospice research. We sought to describe strategies of recruitment, retention, and delivery of NOVELA (short for telenovela), an intervention for hospice family caregivers (HFCG). METHODS: Statistics were kept of every referral, consenting participant, visit session, and intervention activity. We used the Social Marketing Mix Framework to describe recruiting strategies employed and lessons learned. RESULTS: Two hospices in the U.S. Mid-Atlantic region referred 47 HFCG and N = 20 agreed to participate, out of which 50% (N = 10) completed all 4 sessions with an average of 2.8 sessions per person, each lasting an average duration of 13.5 minutes (range 8.0-25.7). The main reason for missing a session was a patient's death (N = 8). Successful recruitment strategies employed in NOVELA included: (a) intensive start-up hospice engagement, (b) remote recruitment and delivery of NOVELA, and (c) scheduling flexibility to work around caregivers' other demands. CONCLUSION: The recruitment and intervention delivery had successes and challenges resulting in the identification of multiple opportunities to strengthen our strategy and inform future studies with HFCGs.

The Pre-implementation Process of Adapting a Culturally Informed Stress Reduction Intervention for Native American Head Start Teachers.

Head Start is a federally funded program for children (3-5 years) from low-income families. In the Fort Peck Native American Reservation, tribal Head Start teachers have reported high stress in supporting children experiencing adverse childhood experiences. Thus, we adapted the Little Holy One intervention (ClinicalTrials.gov: NCT04201184) for the teachers' context and culture to enhance psychological health and well-being. Within a participatory framework, the eight-step ADAPT-ITT methodology was used to guide the adaptation process: assessment; decision; adaptation; production; topical experts; integration; training; and testing. For Step 1, we purposive sampled 27 teachers, ancillary staff, and parents to understand teachers' stress, support mechanisms, and interest in an intervention via focus groups (n = 9) and individual interviews (n = 18). Qualitative data underscored teachers' experiences of stress, depression, and need for support (Step 1). Iterative feedback from a tribal advisory board and Little Holy One designers rendered selection of five lessons (Step 2, 5), which were adapted for the teachers via theater testing (Step 3, 4). Community capacity assessment revealed their ability to implement the intervention (Step 6). Testing of this adapted intervention in a feasibility trial (steps 7, 8) will be reported in a future publication. A rigorous systematic process within a participatory framework allowed intervention adaption based on community input. Leveraging "culture as treatment" may be useful for enhancing psychological health outcomes for Native Americans who historically underutilize existing psychological services.

Native opportunities to stop hypertension: study protocol for a randomized controlled trial among urban American Indian and Alaska Native adults with hypertension.

Introduction: American Indian and Alaska Native (AI/AN) adults experience disproportionate cardiovascular disease (CVD) morbidity and mortality compared to other races, which may be partly attributable to higher burden of hypertension (HTN). Dietary Approaches to Stop Hypertension (DASH) is a high-impact therapeutic dietary intervention for primary and secondary prevention of CVD that can contribute to significant decreases in systolic blood pressure (BP). However, DASH-based interventions have not been tested with AI/AN adults, and unique social determinants of health warrant independent trials. This study will assess the effectiveness of a DASH-based intervention, called Native Opportunities to Stop Hypertension (NOSH), on systolic BP among AI/AN adults in three urban clinics. Methods: NOSH is a randomized controlled trial to test the effectiveness of an adapted DASH intervention compared to a control condition. Participants will be aged ≥18 years old, self-identify as AI/AN, have physician-diagnosed HTN, and have elevated systolic BP (≥ 130 mmHg). The intervention includes eight weekly, tailored telenutrition counseling sessions with a registered dietitian on DASH eating goals. Intervention participants will be provided $30 weekly and will be encouraged to purchase DASH-aligned foods. Participants in the control group will receive printed educational materials with general information about a low-sodium diet and eight weekly $30 grocery orders. All participants will complete assessments at baseline, after the 8-week intervention, and again 12 weeks post-baseline. A sub-sample of intervention participants will complete an extended support pilot study with assessments at 6- and 9-months post-baseline. The primary outcome is systolic BP. Secondary outcomes include modifiable CVD risk factors, heart disease and stroke risk scores, and dietary intake. Discussion: NOSH is among the first randomized controlled trials to test the impact of a diet-based intervention on HTN among urban AI/AN adults. If effective, NOSH has the potential to inform clinical strategies to reduce BP among AI/AN adults.

Nucleotide-dependent activities of FtsA regulate the early establishment of a functional divisome during the Escherichia coli cell cycle.

During cell division in Escherichia coli, the highly conserved tubulin homolog FtsZ polymerizes and assembles into a ring-like structure, called the Z-ring, at the site of septation. For recruitment to the membrane surface, FtsZ polymers directly interact with membrane-associated proteins, predominantly FtsA in E. coli. FtsA shares structural homology with actin and, like actin, hydrolyzes ATP. Yeast actin detects nucleotide occupancy through a sensor region adjacent to the nucleotide binding site and adopts distinct conformations in monomeric and filamentous actin. Bacterial actin homologs also display considerable conformational flexibility across different nucleotide-bound states and polymerize. Here, we show that several amino acid residues proximal to the nucleotide binding site in FtsA are critical for function in vitro and in vivo. Each of these residues are important for ATP hydrolysis, phospholipid (PL) binding, ATP-dependent vesicle remodeling, and recruitment to the divisome in vivo, to varying degrees. Notably, we observed that Ser 84 and Glu 14 are essential for ATP-dependent vesicle remodeling and magnesium-dependent membrane release of FtsA from vesicles in vitro, and these defects likely underlie the loss of function by FtsA(E14R) and FtsA(S84L) in vivo. Finally, we demonstrate that FtsA(A188V), which is associated with temperature-sensitive growth in vivo, is defective for rapid ATP hydrolysis and ATP-dependent remodeling of PL vesicles in vitro. Together, our results show that loss of nucleotide-dependent activities by FtsA, such as ATP hydrolysis, membrane binding and release, and, most importantly, ATP-dependent PL remodeling, lead to failed Z-ring assembly and division defects in cells.

Analysis of action planning, achievement and life purpose statements in an intervention to support caregivers of persons with heart failure.

BACKGROUND: Caregivers of persons living with heart failure (HF) experience uncertainty related to heart failure trajectory and caregiving demands. Caregiver Support is a nurse-led intervention consisting of a well-being assessment, development of a life purpose statement, and action planning related to self-care and support for caregivers. OBJECTIVES: The goal of this study was to describe the caregivers' action plans, action plan achievement and life purpose statements. METHODS: We used inductive content analysis to code life purpose statements and action plans by 2 coders. Descriptive statistics were used to describe the average number of action plans set per caregiver, the average number of themes coded per action plan and life purpose statement, and the status of goal achievement (i.e., by thematic domain, subdomains). Goal achievement was defined categorically: Achieved, not achieved, and not assessed. The achievement rate was calculated as the proportion of achieved action plans out of the total number of assessed action plans. RESULTS: The sample (n = 22) was predominantly women, spousal caregivers, and an average age of 62±14.2 years. Thirty-six percent of caregivers were Black and 41% reported financial strain. Action plans comprised five categories: personal health and well-being, social support, home environment, instrumental support and other. The most common topics of life purpose statements were faith and self-care/actualization. Of 85 action plans, 69 were assessed and 66.7% were achieved. CONCLUSIONS: These findings highlight the diversity of values and needs of caregivers and provides insights for additional person-centered support.
