Abstract

Aim: To explore the resources supporting current nurse practice in the post-emergency country of Liberia, using the nursing intellectual capital framework, as nurses work to meet the targets set by Government of Liberia's Essential Package of Health Services. Design: Case study. Methods: Data were collected in Liberia February–June 2019. Direct observation, semi-structured interviews and photographs were used to investigate how nurse practice is supported. Field notes, transcripts and photographs were coded using both directed and conventional content analysis. Reports were then generated by code to triangulate the data. Results: Thirty-seven nurses at 12 health facilities participated. The intellectual capital supporting inpatient and outpatient nurse practice differs in important ways. Inpatient nurse practice is more likely to be supported by facility-based protocols and trainings, whereas outpatient nurse practice is more likely to be supported by external protocols and trainings, often developed by the Liberian government or non-governmental organizations. This can lead to uneven provision of inpatient protocols and trainings, often favouring private facilities. Similarly, inpatient nurses rely primarily on other nurses at their facilities for clinical support while outpatient nurses often have external professional relationships that provided them with clinical guidance. Conclusion: Much has been accomplished to enable outpatient nurses to provide the primary- and secondary-care target services in the Essential Package of Health Services. However, as the Liberian government and its partners continue to work towards providing certain tertiary care services, developing analogous protocols, trainings and clinical mentorship networks for inpatient nurses will likely be fruitful, and will decrease the burden on individual facilities. Impact: Nurses are often expected to meet new service provision targets in post-emergency states. Further research into how best to support nurses as they work to meet those targets has the potential to strengthen health systems.

Abstract

Background: Recovery of cognitive function after stroke has inter-individual variability. The theory of cognitive reserve offers a potential explanation of the variability in cognitive function after stroke. Objective: This study aimed to investigate the moderating effect of cognitive reserve on the relationship between the stroke severity and cognitive function after stroke. Materials and methods: A total of 220 patients with Acute Ischemic Stroke (AIS) were recruited in 2021 from two stroke centers in Nanjing, China. The National Institutes of Health Stroke Scale (NIHSS) was used to assess stroke severity upon admission. Cognitive Reserve Index questionnaire (CRIq) and validated Montreal Cognitive Assessment, Changsha Version (MoCA-CS) were used to assess cognitive reserve and cognitive function within 7 days after stroke onset, respectively. A series of multivariate linear regression models were applied to test the moderating effect of cognitive reserve. Results: Patients with a higher level of cognitive reserve had better cognitive function after stroke compared with those with a lower level of cognitive reserve (β = 0.074, p = 0.003). The interaction of NIHSS and cognitive reserve was statistically significant (β = −0.010, p = 0.045) after adjusting for some key covariates [e.g., age, marital status, Oxfordshire Community Stroke Project (OCSP) classification, Trial of ORG 10172 in Acute Stroke Treatment (TOAST) classification, cerebral vascular stenosis, diabetes and atrial fibrillation]. Conclusion: Cognitive reserve may help to buffer the effect of stroke-related pathology on cognitive decline in Chinese acute stroke patients. Enhancing cognitive reserve in stroke patients may be one of the potential strategies for preventing vascular dementia.

Abstract

Prior studies focused on circulating microRNAs and the risk for complex diseases have shown inconsistent findings. The majority of studies focused on European and East Asian racial or ethnic groups, however, ancestry was not typically reported. We evaluated the risk for type 2 diabetes as an exemplar to show that race and ethnic group may contribute to inconsistent validation of previous findings of associations with microRNAs.

Abstract

Many studies of heart failure (HF) self-care have been conducted since the last update of the situation-specific theory of HF self-care. OBJECTIVE: The aim of this study was to describe the manner in which characteristics of the problem, person, and environment interact to influence decisions about self-care made by adults with chronic HF. METHODS: This study is a theoretical update. Literature on the influence of the problem, person, and environment on HF self-care is summarized. RESULTS: Consistent with naturalistic decision making, the interaction of the problem, person, and environment creates a situation in which a self-care decision is needed. Problem factors influencing decisions about HF self-care include specific conditions such as cognitive impairment, diabetes mellitus, sleep disorders, depression, and symptoms. Comorbid conditions make HF self-care difficult for a variety of reasons. Person factors influencing HF self-care include age, knowledge, skill, health literacy, attitudes, perceived control, values, social norms, cultural beliefs, habits, motivation, activation, self-efficacy, and coping. Environmental factors include weather, crime, violence, access to the Internet, the built environment, social support, and public policy. CONCLUSIONS: A robust body of knowledge has accumulated on the person-related factors influencing HF self-care. More research on the contribution of problem-related factors to HF self-care is needed because very few people have only HF and no other chronic conditions. The research on environment-related factors is particularly sparse. Seven new propositions are included in this update. We strongly encourage investigators to consider the interactions of problem, person, and environmental factors affecting self-care decisions in future studies.

Abstract

Nursing students receive limited education to prepare them for providing quality nursing care to people with disabilities. The aim of this article is to provide the state of the science, or what is known, about nursing simulation with disability content to provide direction for nursing education and research in the future. Thirteen studies were reviewed and appraised in this integrative review. This review revealed three major student-related study outcomes for simulation activities: (a) empathy, (b) understanding and awareness, and (c) communication and disability. Only a few studies integrated a definition of a disability and specified the disability model to guide the development of the simulation activity. This review revealed limited research on the use of simulation with disability content in nursing education. The findings indicate there is a need for nurse educators and researchers to use best practices, such as a competency-based approach, when integrating simulation activities with disability content into the nursing curriculum.

Abstract

ObjectivesTo identify and examine heterogeneous trajectories of general health status (GHS) and depressive symptoms (DS) among persons with cognitive impairment (PCIs). Methods: We use group-based trajectory models to study 2361 PCIs for GHS and 1927 PCIs for DS from the National Health and Aging Trends Survey 2011-2018, and apply multinomial logistic regressions to predict identified latent trajectory group memberships using individual characteristics. Results: For both GHS and DS, there were six groups of PCIs with distinct trajectories over a 7-year period. More than 40% PCIs experienced sharp declines in GHS, and 35.5% experienced persistently poor GHS. There was greater heterogeneity in DS trajectories with 55% PCIs experiencing improvement, 16.4% experiencing persistently high DS, and 30.5% experiencing deterioration. Discussion: The GHS trajectories illustrate the heavy burden of poor and declining health among PCIs. Further research is needed to understand the factors underlying stable or improving DS despite declining GHS.

Abstract

Background: physical functioning impairment is common among persons with cognitive impairment, but little is known about physical functioning trajectories across the US population or how trajectories may differ among persons with dementia and mild cognitive impairment (MCI). Objective: To examine trajectories of physical functioning among persons with MCI and dementia in the USA. Design: we used data from the National Health and Aging Trends study (NHATS) 2011-18. Physical functioning was assessed using the NHATS Expanded Short Physical Performance Battery. Participants: The 661 individuals with MCI and 980 individuals with dementia were included in this study. Methods: we applied group-based trajectory models to identify latent groups and estimate their trajectories. Multinomial logistic regressions were applied to examine relationships between sociodemographic and health characteristics and trajectory group memberships. Results: both MCI-and dementia-specific trajectories differed at baseline levels and declined at varying rates across groups. Approximately, 78.43% of persons with MCI were in trajectories with a moderate rate of decline, with only 9.75% in a trajectory with good physical function and 11.82% with poor physical function without as much change over time. Among persons with dementia, approximately 81.4% experienced moderate or fast declines, and 18.52% with virtually no functional ability remained at this same low level. Worse physical functioning trajectories were found among persons who were females, Blacks, with at least four comorbidities, and among persons who had a low socioeconomic status. Conclusions: persons with both dementia and MCI experienced steady declines in physical functioning. Socioeconomically disadvantaged groups have worse physical functioning trajectories.

Abstract

Context: During the COVID-19 pandemic, community-based research studies experienced prolonged shutdowns unless able to pivot to remote study procedures. Objectives: To describe the revision of two National Institutes of Health funded community-based palliative-focused clinical trials serving underserved populations to accommodate remote subject enrollment and examine its impact. Methods: Transitioning to remote processes required multiple protocol and procedural changes including: altering informed consent processes; reducing the number of surveys administered; adding internet access as an inclusion criterion. To understand technological challenges, a screening tool was developed for one study to identify potentially eligible subjects’ technology abilities and accessibility. Results: Subjects’ limited access to the internet and internet-enabled devices and discomfort with technology led to changes in recruitment patterns. Lack of familiarity with technology increased the amount of time it took research team members and subjects to connect remotely. Patients with significant cognitive and/or sensory deficits were at higher risk of experiencing fatigue during remote study visits leading to streamlining of data collection. A researcher-developed technology screening tool found that potential subjects were not comfortable with videoconferencing through Zoom expressing a preference for phone visits. Reduced travel time made scheduling remote study visits more efficient. Conclusion: Future community- and home-based palliative care trials must consider the best way to utilize remote recruitment, enrollment, and data collection processes to increase efficiency and reduce costs. Researchers should consider technology accessibility and train staff to ensure the greatest possible opportunity to recruit underserved populations who have traditionally been underrepresented in research studies.

Abstract

Background: Accumulating evidence links ultra-processed foods to poor diet quality and chronic diseases. Understanding dietary trends is essential to inform priorities and policies to improve diet quality and prevent diet-related chronic diseases. Data are lacking, however, for trends in ultra-processed food intake. Objectives: We examined US secular trends in food consumption according to processing level from 2001 to 2018. Methods: We analyzed dietary data collected by 24-h recalls from adult participants (aged >19 y; N = 40,937) in 9 cross-sectional waves of the NHANES (2001-2002 to 2017-2018). We calculated participants' intake of minimally processed foods, processed culinary ingredients, processed foods, and ultra-processed foods as the relative contribution to daily energy intake (%kcal) using the NOVA framework. Trends analyses were performed using linear regression, testing for linear trends by modeling the 9 surveys as an ordinal independent variable. Models were adjusted for age, sex, race/ethnicity, education level, and income. Consumption trends were reported for the full sample and stratified by sex, age groups, race/ethnicity, education level, and income level. Results: Adjusting for changes in population characteristics, the consumption of ultra-processed foods increased among all US adults from 2001-2002 to 2017-2018 (from 53.5 to 57.0 %kcal; P-trend < 0.001). The trend was consistent among all sociodemographic subgroups, except Hispanics, in stratified analyses. In contrast, the consumption of minimally processed foods decreased significantly over the study period (from 32.7 to 27.4 %kcal; P-trend < 0.001) and across all sociodemographic strata. The consumption of processed culinary ingredients increased from 3.9 to 5.4 %kcal (P-trend < 0.001), whereas the intake of processed foods remained stable at ∼10 %kcal throughout the study period (P-trend = 0.052). Conclusions: The current findings highlight the high consumption of ultra-processed foods in all parts of the US population and demonstrate that intake has continuously increased in the majority of the population in the past 2 decades.

Abstract

Purpose of Review: Poor diet quality is the leading risk factor related to the overall cardiometabolic disease burden in the USA and globally. We review the current evidence linking ultra-processed foods and cardiometabolic health risk and provide recommendations for action at the clinical and public health levels. Recent Findings: A growing body of evidence conducted in a variety of study populations supports an association between ultra-processed food intake and increased risk of metabolic syndrome, hypertension, type 2 diabetes, overweight and obesity trajectories, and cardiovascular disease. The strongest evidence is observed in relation to weight gain and obesity among adults, as this association is supported by high-quality epidemiological and experimental evidence. Summary: Accumulating epidemiologic evidence and putative biological mechanisms link ultra-processed foods to cardiometabolic health outcomes. The high intake of ultra-processed foods in all population groups and its associated risks make ultra-processed foods an ideal target for intensive health promotion messaging and interventions.

Abstract

Background and Objectives: Though many studies have examined the service utilization of dementia caregivers, there is limited empirical evidence from Asian Americans in this field. Guided by Andersen’s behavioral model of health services use, we aimed to understand what factors were associated with utilizing multiple types of services among Chinese American dementia caregivers. Research Design and Methods: We collected survey data from 134 Chinese dementia caregivers in New York City. Logistic regression models were conducted to test the associations between predisposing, enabling, and need factors and the likelihood of using tangible (home health aide, adult daycare, respite care), educational (lectures and workshops), and psychological (peer support groups and psychological counseling) support services. Results: Several variables conceptualized by Andersen’s model, including caregiver’s knowledge about services, caring tasks, length of care and burden, and care recipient’s physical and cognitive deteriorations, were significantly associated with higher possibilities of using multiple types of services. Three sociocultural factors—residing in Chinatown, availability of alternative family caregivers, and diagnosis of cognitive deterioration—were also associated with higher likelihood of using educational or psychological services. Discussion and Implications: The findings extend the existing literature on service utilization of caregivers by highlighting the importance of distinguishing types of services and considering sociocultural factors in future research and practice.

Abstract

Objective: The purpose of this integrative review is to examine the literature on vaccine hesitancy among American healthcare workers during the COVID-19 vaccine rollout. Methods: A review of quantitative literature on acceptance, intention, refusal, or hesitation to accept the COVID-19 vaccine was conducted, searching in PubMed, Cumulative Index for Nursing and Allied Health Literature, PsycINFO, and Web of Science. Because of the immediacy of the topic, research letters were included in addition to articles. The 18 publications were appraised for quality using the Critical Appraisal Checklist for Cross-Sectional Studies by the Center for Evidence-Based Management. Results: Estimates of vaccine hesitancy among healthcare workers were similar to the general population. The literature indicates demographic characteristics associated with vaccine hesitancy, including being younger, female, Black, Hispanic, or Latinx. However, examination of the demographic data also points to gaps in the understanding and implications of those characteristics. The newness or perceived rush of vaccine development and implementation were the most cited sources for hesitancy. Conclusion: The studies in this review give clear areas of need for translational research on dissemination and implementation relating to the correlational data, including in areas of comorbid, diasporic, and reproductive health concerns. However, with the gravity of the pandemic and quick arrival of the COVID-19 vaccine happening in the midst of an infodemic, adjunctive interventions could be warranted to combat hesitancy.

Abstract

Purpose: Gender affirmation lessens mental health disparities among transgender and gender nonbinary (TGNB) persons. However, the concept of what it means to be affirmed in one's gender has not been fully explored, nor has the impact of gender affirmation on other health indicators been determined. The purpose of this study was to explore the meaning of gender affirmation among a sample of TGNB persons. Methods: This qualitative, narrative inquiry study consisted of individual, in-depth, semi-structured interviews with a convenience sample of 20 TGNB persons. Descriptive content analysis was conducted to discover themes. Results: This study identified salient themes regarding the multiple levels of affirmation (including internal, external and societal) needed to achieve the overall goal of living an optimal life described as “being seen, heard and even celebrated” as TGNB. Conclusion: Results of this study have clinical, educational, research, and policy implications. Future research should explore the impact of gender affirmation on important health indicators in the TGNB community, differences in the experiences and needs among subgroups of TGNB persons, and the potential impact of nurses on the health experience of TGNB persons across the spectrum of transition.
