Abstract

Objective: To determine the percentage of children with nonalcoholic fatty liver disease (NAFLD) in whom intervention for low-density lipoprotein cholesterol or triglycerides was indicated based on National Heart, Lung, and Blood Institute guidelines. Study design: This multicenter, longitudinal cohort study included children with NAFLD enrolled in the National Institute of Diabetes and Digestive and Kidney Diseases Nonalcoholic Steatohepatitis Clinical Research Network. Fasting lipid profiles were obtained at diagnosis. Standardized dietary recommendations were provided. After 1 year, lipid profiles were repeated and interpreted according to National Heart, Lung, and Blood Institute Expert Panel on Integrated Guidelines for Cardiovascular Health and Risk Reduction. Main outcomes were meeting criteria for clinically actionable dyslipidemia at baseline, and either achieving lipid goal at follow-up or meeting criteria for ongoing intervention. Results: There were 585 participants, with a mean age of 12.8 years. The prevalence of children warranting intervention for low-density lipoprotein cholesterol at baseline was 14%. After 1 year of recommended dietary changes, 51% achieved goal low-density lipoprotein cholesterol, 27% qualified for enhanced dietary and lifestyle modifications, and 22% met criteria for pharmacologic intervention. Elevated triglycerides were more prevalent, with 51% meeting criteria for intervention. At 1 year, 25% achieved goal triglycerides with diet and lifestyle changes, 38% met criteria for advanced dietary modifications, and 37% qualified for antihyperlipidemic medications. Conclusions: More than one-half of children with NAFLD met intervention thresholds for dyslipidemia. Based on the burden of clinically relevant dyslipidemia, lipid screening in children with NAFLD is warranted. Clinicians caring for children with NAFLD should be familiar with lipid management.

Abstract

Background: We have a limited understanding of the biological underpinnings of symptoms in heart failure (HF). Objectives: The purpose of this paper was to compare relationships between peripheral biomarkers of HF pathogenesis and physical symptoms between patients with advanced versus moderate HF. Methods: This was a two-stage phenotype sampling cohort study wherein we examined patients with advanced HF undergoing ventricular assist device implantation in the first stage, and then patients with moderate HF (matched adults with HF not requiring device implantation) in the second stage. Linear modeling was used to compare relationships among biomarkers and physical symptoms between cohorts. Results: Worse myocardial stress, systemic inflammation and endothelial dysfunction were associated with worse physical symptoms in moderate HF (n=48), but less physical symptom burden in advanced HF (n=48). Conclusions: Where patients are in the HF trajectory needs to be taken into consideration when exploring biological underpinnings of physical HF symptoms.

Abstract

Background: Self-perceived uselessness is associated with poorer health in older adults. However, it is unclear whether there is a difference in self-perceived uselessness between centenarians and non-centenarians, and if so, which factors contributed to the difference. Methods: We used four waves of a nationwide longitudinal dataset from 2005 to 2014 in China to investigate these research goals. We first performed multinomial logit regression models to examine the risk of the high or moderate frequency of self-perceived uselessness relative to the low frequency among centenarians (5778 persons) in comparison with non-centenarians aged 65-99 (20,846 persons). We then conducted a cohort analysis for those born in 1906-1913, examining differences in self-perceived uselessness between those centenarians and those died between ages 91 and 99 during 2005-2014. Results: Compared to persons aged 65-79, centenarians had 84% (relative risk ratio (RRR) = 1.84, 95% CI:1.69-2.01) and 35% (RRR = 1.35, 95% CI: 1.25-1.46) higher risk to have the high frequency and the moderate frequency of feeling useless versus low frequency, respectively, when only demographic factors were controlled for. However, centenarians had 31% (RRR = 0.69, 95% CI: 0.54-0.88), 43% (RRR = 0.57, 95% CI: 0.49-0.68), and 25% (RRR = 0.75, 95% CI: 0.67-0.83) lower risk, respectively, to have the high frequency of self-perceived uselessness relative to the low frequency when a wide set of study covariates were controlled for. In the case of the moderate versus the low frequency of self-perceived uselessness, the corresponding figures were 18% (RRR = 0.82, 95% CI: 0.66-1.02), 22% (RRR = 0.78, 95%CI: 0.67-0.90), and 13% (RRR = 0.87, 95% CI: 0.79-0.96), respectively. The cohort analysis further indicates that those who became centenarians were 36-39% less likely than those died at ages 91-94 to report the high and the moderate frequencies of self-perceived uselessness versus the low frequency; no difference was found between centenarians and those died at ages 95-99. In both period and cohort analyses, behavioral and health-related factors affected the perception substantially. Conclusions: Overall, centenarians were less likely to perceive themselves as useless compared to non-centenarians of younger birth cohorts when a wide set of covariates were considered and non-centenarians of the same birth cohort. How centenarians manage to do so remains an open question. Our findings may help improve our understanding about the longevity secrets of centenarians.

Abstract

In this chapter, the intuitive link between balanced, healthy, and supportive psychosocial work environments and a variety of vitally important patient, nurse, and organizational outcomes is discussed with reference to a number of clearly defined and well-researched concepts. Among the essential concepts that ground the rest of the book is the notion of a bundle of factors that provide a context for nurses' work and are known collectively as the practice environment. Landmark studies that focused specifically on nurses' experiences of their work environments in exemplary hospitals examined so-called Magnet hospitals, leading to a framework that describes the practice environment and its linkage with professional well-being, occupational stress, and quality of practice and productivity. Many ideas and models have obvious connections to the notion of practice environment such as Job Demand- Control-Support model, worklife dimensions and burnout, concepts related to burnout such as compassion fatigue, and work engagement as a mirror image concept of burnout, as well as notions of empowerment and authentic leadership. These concepts have been chosen for discussion here based on critical masses of evidence pointing to their usefulness in healthcare management and specifically in the management of nursing services. Together all of these concepts and supporting research and scholarship speak to a common point: intentional leadership approaches, grounded in a comprehensive understanding of nurses' psychosocial experiences of their work, are essential to nurses' abilities to respond to complex patients' needs in rapidly changing healthcare contexts and socioeconomic conditions.

Abstract

Translation science is the process of transdisciplinary teams accelerating the discoveries and findings from the laboratory, clinic, and community, and moving them into interventions that improve the health of individuals and populations. These discoveries include new forms of diagnostics, novel therapeutics, and innovative medical and behavioral interventions. The role of nurses in translational science is a natural fit, given the transdisciplinary nature of their work, the evolving role of nursing science, and the high-level of patient and family-centered interaction that nurses have as clinicians and scientists. As Clinical and Translational Science Awards were being developed across the nation, nurses felt the need for a stronger and more united voice. In 2010, nurse leaders in this field started the Nurse Scientist-Translational Interest Research Group (NS-TRIG). The group is now in its eighth year and provides a forum for nurse scientists to connect, communicate and collaborate. The purpose of this article is to describe the formation and background of the NS-TRIG, describe our meeting structure and provide examples of content. We also describe a summary of major accomplishments and work products of the NS-TRIG, and consider lessons learned and future directions of the group.

Abstract

Background: Higher sugar consumption may increase cancer risk by promoting insulin-glucose dysregulation, oxidative stress, hormonal imbalances, and excess adiposity. This prospective study investigates the association between dietary sugars (fructose and sucrose) and sugary foods and beverages in relation to combined and site-specific (breast, prostate, colorectal) adiposity-associated cancers. Methods: The analytic sample consisted of 3,184 adults, aged 26–84 years, from the Framingham Offspring cohort. Diet data were first collected between 1991 and 1995 using a food frequency questionnaire. Intakes of fructose, sucrose, sugary foods, and sugary beverages (fruit juice and sugar-sweetened beverages) were derived. Participants were followed up until 2013 to ascertain cancer incidence; 565 doctor-diagnosed adiposity-related cancers, including 124 breast, 157 prostate, and 68 colorectal cancers occurred. Multivariable-adjusted Cox proportional hazards models were used to evaluate associations. Tests for interaction with BMI and waist circumference were conducted. Results: No associations were observed between fructose, sucrose, sugary food consumption, and combined incidence of adiposity-related cancers or the examined site-specific cancers. While total consumption of sugary beverages was not associated with site-specific cancer risk, higher intakes of fruit juice were associated with 58% increased prostate cancer risk (HR: 1.58; 95% CI, 1.04–2.41) in multivariable-adjusted models. In exploratory stratified analyses, higher sugary beverage intakes increased overall adiposity-related cancer risk by 59% in participants with excessive central adiposity (HR: 1.59; 95% CI, 1.01–2.50; P trend ¼ 0.057). Conclusions: In this cohort of American adults, higher sugary beverage consumption was associated with increased cancer risk among participants with central adiposity. Impact: These analyses suggest that avoiding sugary beverages represents a simple dietary modification that may be used as an effective cancer control strategy.

Abstract

High sugar intake may increase cancer risk by promoting insulin-glucose dysregulation, oxidative stress, inflammation, and body adiposity, but epidemiologic evidence is unclear. Associations between dietary sugars and lifestyle-related cancer risk from longitudinal studies were evaluated. We systematically searched PubMed, Embase, and CINAHL and identified 37 prospective cohort studies (1990-2017) reporting multivariable adjusted risk estimates for dietary sugars in relation to cancer. Of 15 and 14 studies on total sugar and sucrose respectively, 11 reported a null association in relation to cancer. Of 14 studies on fructose, 8 reported null associations, and 2 reported protective and 4 reported detrimental associations. In two of five studies on added sugars, a 60-95% increased cancer risk was observed with higher intakes. In 8 of 15 studies on sugary foods and beverages, a 23-200% higher cancer risk was observed with higher sugary beverage consumption. In conclusion, most studies were indicative of a null association, but suggestive detrimental associations were reported for added sugars and sugary beverages.

Abstract

Background: Maternal and newborn mortality remains high in Liberia. There is a severe rural–urban gap in accessibility to health care services. A competent midwifery workforce is able to meet the needs of mothers and newborns. Evidence shows that competence can be assured through initial education along with continuous professional development (CPD). In the past, CPD was not regulated and coordinated in Liberia which is cpommon in the African region. Aim: To Support a competent regulated midwifery workforce through continuous professional development. Methodology: A new CPD model was developed by the Liberian Board for Nursing and Midwifery. With its establishment, all midwives and nurses are required to undertake CPD programmes consisting of certified training and mentoring in order to renew their practicing license. The new model is being piloted in one county in which regular mentoring visits that include skills training are being conducted combined with the use of mobile learning applications addressing maternity health issues. Quality control of the CPD pilot is assured by the Liberian Board for Nursing and Midwifery. The mentoring visits are conducted on a clinical level but are coordinated on the national and county level. Successes and sustainability: CPD using mobile learning on smartphones and regular mentoring visits not only improved knowledge and skills of midwives and nurses but also provided a solution to enhance accessibility in rural areas through improved communication and transportation, as well as improved career development of health personnel working in remote areas. Mentors were trained on a national, county, and health facility level in the pilot county with mentoring visits conducted regularly. Conclusion: The CPD programme of the Liberian Board for Nursing and Midwifery, currently in pilot-testing by various partners, aims to highlight the positive impact of the coordinating role of both the regulatory body and health authorities. Using regular process and programme reviews to improve capacity, knowledge, and skills of health professionals.

Abstract

Hypoplastic right heart syndrome (HRHS) is a rare congenital defect characterized by underdeveloped and malformed structures of the right heart. Familial recurrence of HRHS indicates genetic factors contribute to its etiology. Our study investigates the presence of copy number variants (CNVs) in HRHS cases. We genotyped 42 HRHS cases identified from live births throughout California (2003–2010) using the Illumina HumanOmni2.5-8 array. We identified 14 candidate CNVs in 14 HRHS cases (33%) based on the genes included in the CNVs and their functions. Duplications overlapping part of ERBB4 were identified in two unrelated cases. ERBB4 is a neuregulin receptor with a pivotal role in cardiomyocyte differentiation and heart development. We also described a 7.5 Mb duplication at 16q11-12. Multiple genes in the duplicated region have previously been linked to heart defects and cardiac development, including RPGRIP1L, RBL2, SALL1, and MYLK3. Of the 14 validated CNVs, we identified four CNVs in close proximity to genes linked to the Wnt signaling pathway. This study expands on our previous work supporting the role of genetics in HRHS. We identified CNVs affecting crucial genes and signaling pathways involved in right heart development. ERBB4 and duplication of the 16q11-12 region are important areas for future investigation.

Abstract

Background: Lifestyle changes and treatment adherence still constitute a challenge to healthcare providers involved in the care of persons with hypertension. The lack of validated instruments measuring the ability of hypertensive patients to manage their disease has slowed research progress in this area. The Self-care of Hypertension Inventory, originally developed in the United States, consists of 23 items divided across 3 scales: Self-care Maintenance, Self-care Management, and Self-care Confidence. These scales measure how well patients with hypertension adhere to treatment and manage elevated blood pressure, as well as their confidence in their ability to perform self-care. A rigorous cross-cultural adaptation and validation process is required before this instrument can be used in other countries. Objective: The aims of this study were to translate the Self-care of Hypertension Inventory into Brazilian Portuguese with cross-cultural adaptation and to evaluate interobserver reliability and temporal stability. Methods: This methodological study involved forward translation, synthesis of forward translations, back-translation, synthesis of back-translations, expert committee review, and pretesting. Interobserver agreement and the temporal stability of the scales were assessed. Results: The expert committee proposed semantic and cultural modifications to some items and the addition of guidance statements to facilitate administration of the scale. Interobserver analysis demonstrated substantial agreement. Analysis of temporal stability showed near-perfect agreement. Conclusions: Cross-cultural adaptation of the Self-care of Hypertension Inventory successfully produced a Portuguese-language version of the instrument for further evaluation of psychometric properties. Once that step is completed, the scale can be used in Brazil.

Abstract

Background: This study aims to examine the lay perceptions of successful aging among elderly Chinese in Hawai‘i, the state has the highest life expectancy in the United States. Method: Principal components factor analysis and logistic regression models were used to analyze survey data collected among 136 respondents who were asked to evaluate the importance of 12 successful aging items developed in Asian societies involving the Chinese population. Results: Results from factor analysis reveal three distinct factors out of the 12 items of successful aging—(a) psychosocial and economic well-being, (b) physical well-being, and (c) social support from adult children. The former two factors were perceived as important dimensions of successful aging by most survey participants, and approximately 35%-41% respondents viewed items composing Factor 3 as important. Discussion: Results suggest that elderly Chinese in Hawai‘i have unique perceptions of successful aging that go beyond the Rowe and Kahn’s biomedical model to include more psychosocial components. In addition, their perceptions are similar to but slightly different from perceptions of elderly Chinese in China and Singapore in levels of familism. Our findings indicate cultural variation of successful aging.

Abstract

Members of the lesbian, gay, bisexual, transgender, and queer (LGBTQ) community have historically faced prejudices, often resulting in significant health disparities. Critical care nurses have a duty to provide all patients, regardless of their sexual orientation or gender identity, with the best possible care. This article examines a framework for LGBTQ-sensitive care as well as best practices and additional resources.

Abstract

Aims and objectives: To describe differences in fatigue severity in a sample of adult Puerto Rican patients during and postcancer treatments. Background: Hispanics, including Puerto Ricans, are an understudied population who are under-represented in clinical trials, especially in symptom research. Although symptom management is a clinical priority in oncology care, treatment-related differences in Puerto Rican cancer patients’ report of fatigue severity have not been well described. Design/Methods: A cross-sectional survey was conducted from data of self-report of 138 Puerto Rican patients during and postcancer treatments at two ambulatory facilities located in San Juan, Puerto Rico. Fatigue severity was assessed using the Fatigue subscale from the Functional Assessment of Cancer Therapy-Fatigue quality of life questionnaire Spanish version. Differences in fatigue severity across type of treatment (radiation therapy, chemotherapy, combined radiation chemotherapy and post-treatment) were evaluated using nonparametric (Kruskal–Wallis and Mann–Whitney test) statistical tests. Results: The majority of the participants had prostate (33%) and breast (32%) cancers and were receiving radiation therapy (43%) or chemotherapy (28%). The Kruskal–Wallis test showed that there was a statistically significant difference in fatigue scores between the different four treatment conditions, χ2(3) = 39.1, p =.001 with patients on combined radiation chemotherapy or chemotherapy alone experiencing more severe fatigue. Conclusions: Findings from the current study suggest that type of treatment is a key component of the symptom burden of fatigue among the Puerto Rican oncology population. Specially, patients receiving combined therapy or chemotherapy alone were at increased risk for experiencing severe fatigue, compared to radiation therapy and post-treatment patients. Relevance to clinical practice: With the worldwide increase in migration of Puerto Rican families, nurses need to recognise that type of treatment is a key component of the symptom burden of fatigue among the Puerto Rican population. The results of this study will improve understanding of treatment-related fatigue to identify therapeutic targets and improve quality of life of patients.

Abstract

The knowledge base of cancer-related symptoms is increasing; yet, limited attention has been given to provide evidence on differences in the perception of cancer symptoms between ethnic groups, especially in the Hispanic Puerto Rican (PR) population. To examine whether there are significant differences in the severity, distress, interference, and frequency of cancer symptoms between island Hispanic PR and mainland non-Hispanic whites. In this secondary data analysis, data from 109 Hispanic PR was matched by age, gender and cancer diagnosis with data from non-Hispanic whites. Cancer symptoms were assessed using the Cancer Symptom Scale (CSS). Mann–Whitney statistical test was used to evaluate pairwise differences between Hispanic PR and non-Hispanic whites on symptoms from the CSS. There were significant differences on some symptoms including PR reporting: (a) more intense itching, swelling, taste change, difficulty sleeping, bloating, depression, sadness, worry, and nervousness; (b) significantly greater distress about taste change, appetite, anxiety, depression, worry, and feeling nervous; (c) rash, anxiety, depression, sadness, and nervousness interfered the most with their daily lives; and, (d) that the frequency of occurrence of the symptoms of pain, itching, dizziness, taste change, anxiety, sadness, and nervousness was higher compared to non-Hispanic whites. PR cancer patients are at increased risk for experiencing greater severity of cancer symptoms compared to non-Hispanic whites. But because the Hispanic oncology population does not always report symptoms, risking under-assessment and under-management, this suggests there may be a greater need for symptoms surveillance for this population.

Abstract

Background: The Institute of Medicine (IOM) report, The Future of Nursing, included recommendations to increase nurse diversity, the percent of nurses obtaining a bachelor's degree, and inter-professional education. Purpose: The purpose of this paper is to report the progress toward achievement of these recommendations. Methods: We used a longitudinal, multi-state data from four cohorts of nurses newly licensed in 2004 to 2005, 2007 to 2008, 2010 to 2011, and 2014 to 2015 to examine and compare the trends. Finding: The percentage of males who became licensed increased, from 8.8% in 2004 to 2005 cohort to 13.6% in the 2014 to 2015 cohort. The percentage of white-non-Hispanic nurses who were licensed decreased from 78.9% in 2007 to 2008 to 73.8% in 2014 to 2015. These differences primarily reflect an increase in white-Hispanic nurses. More nurses are obtaining a bachelor's degree as their first professional degree, from 36.6% in 2004 to 2005 cohort to 48.5% in 2014 to 2015 cohort. About 40% of the 2014 to 2015 cohort reported that they learned to work in inter-professional teams. Collegial nurse-physician relations had an upward positive trajectory over time increasing almost 7%. Discussion: The diversity and education of new nurses have increased, but are short of meeting the IOM recommendations.

Abstract

Objective: This study aims to examine the association between oral health and the decline in functional status among middle-aged and older adults in the United States. Method: Generalized estimation equation (GEE) Poisson regression models with robust standard errors were used to analyze the longitudinal panel data (2008-2014) from the Health and Retirement Study (N = 1,243). Oral health was evaluated using self-rated oral health, poor mouth condition, and tooth loss. Decline in functional status was assessed by disabilities in activities of daily living (ADLs) and instrumental activities of daily living (IADLs). Results: Respondents with poor oral health were more likely to experience decline in ADLs/IADLs. Adjusting for sociodemographics and comorbidities attenuated the effects of oral health. Discussion: Findings suggest that oral health might be one of the important predictors of functioning decline in late life, after adjusting sociodemographics and comorbidities.

Abstract

Background: Nurses are the main providers of patient education in inpatient and outpatient settings. Unfortunately, nurses may lack knowledge of chronic medical conditions, such as heart failure. Method: The purpose of this one-group pretest– posttest intervention was to determine the effectiveness of teaching intervention on nurses’ knowledge of heart failure self-care principles in an ambulatory care setting. The sample consisted of 40 staff nurses in ambulatory care. Nurse participants received a focused education intervention based on knowledge deficits revealed in the pretest and were then resurveyed within 30 days. Nurses were evaluated using the valid and reliable 20-item Nurses Knowledge of Heart Failure Education Principles Survey tool. Results: The results of this project demonstrated that an education intervention on heart failure self-care principles improved nurses’ knowledge of heart failure in an ambulatory care setting, which was statistically significant (p, .05). Conclusion: Results suggest that a teaching intervention could improve knowledge of heart failure, which could lead to better patient education and could reduce patient readmission for heart failure.
