Abstract

Dietary variety is positively correlated with energy intake in most studies. However, the associations between dietary variety and measures of body adiposity are inconsistent in the literature, which limits the development of clear national nutrition recommendations regarding dietary variety. In the present systematic review, we critically evaluate the associations between dietary variety and measures of body adiposity among healthy adults within the existing literature. We conducted a systematic search of the MEDLINE and Web of Science databases in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement to examine these associations. We identified twenty-six studies in total that investigated the associations between dietary variety and body adiposity measures. Total variety was non-significantly associated with body adiposity in most studies, while variety in recommended foods was either inversely associated (six out of ten studies) or non-significantly associated (three out of ten studies) with body adiposity. Conversely, variety in non-recommended foods (i.e. sources of added sugars and solid fats) increased the likelihood of excess adiposity in most studies (six out of nine studies). Definitions and measurement of dietary variety were inconsistent across studies and contributed to some of the discrepancies noted in the literature. In conclusion, among the studies that met the inclusion criteria for the present review, dietary variety was inconsistently associated with body adiposity in diverse populations. Using consistent and specific definitions of dietary variety may help provide further insight into the associations between dietary variety and excess adiposity before definitive public health messages are ma

Abstract

Objective: To examine the associations of four distinct nursing care organizational models with patient safety outcomes. Design: Cross-sectional correlational study. Using a standardized protocol, patients' records were screened retrospectively to detect occurrences of patient safety-related events. Binary logistic regression was used to assess the associations of those events with four nursing care organizational models. Setting: Twenty-two medical units in 11 hospitals in Quebec, Canada, were clustered into 4 nursing care organizational models: 2 professional models and 2 functional models. Participants: Two thousand six hundred and ninety-nine were patients hospitalized for at least 48 h on the selected units. Main Outcome Measure: Composite of six safety-related events widely-considered sensitive to nursing care: medication administration errors, falls, pneumonia, urinary tract infection, unjustified restraints and pressure ulcers. Events were ultimately sorted into two categories: events 'without major' consequences for patients and events 'with' consequences. Results: After controlling for patient characteristics, patient risk of experiencing one or more events (of any severity) and of experiencing an event with consequences was significantly lower, by factors of 25-52%, in both professional models than in the functional models. Event rates for both functional models were statistically indistinguishable from each other. Conclusions: Data suggest that nursing care organizational models characterized by contrasting staffing, work environment and innovation characteristics may be associated with differential risk for hospitalized patients. The two professional models, which draw mainly on registered nurses (RNs) to deliver nursing services and reflect stronger support for nurses' professional practice, were associated with lower risks than are the two functional models.

Abstract

Introduction Limited research has examined primary care providers' communication with patients about maintaining cognitive functioning. Our study's objective was to compare the perceptions of consumers and primary care providers related to beliefs and communication practices about lifestyle behaviors beneficial for overall health and for maintaining cognitive functioning. Methods In 2009, we submitted 10 questions to Porter Novelli's HealthStyles survey and 6 questions to their DocStyles survey. We compared consumers' (n = 4,728) and providers' (n = 1,250) beliefs, practices, and information sources related to maintaining health and cognitive functioning. We made comparisons using nonparametric statistics. Results Approximately 76% of consumers considered their health to be good or very good; 73.4% were concerned or very concerned about the possibility that their memory may worsen with age. Women were significantly more concerned than men, and white consumers were more concerned than black and Hispanic consumers. Consumers reported they believed that intellectual stimulation (86.6%), physical activity (82.6%), and healthful diet (82.5%) prevented or delayed cognitive impairment. Providers reported advising patients to reduce cognitive impairment riskthrough physical activity (85.9%), intellectual stimulation (80.3%), and social involvement (67.4%). Few consumers (7.8%) reported receiving this information from providers but reported learning about strategies to maintain memory, primarily from television (50.1%), magazines (44.1%), and newspapers(33.7%). Conclusion Providers reported advising patients about how to reduce risks of cognitive impairment. Consumers reported receiving this information from other sources. Findings suggest a need to examine and assess mediamessages and to better understand patient-provider communication about cognitive functioning.

Abstract

This study aimed to examine the experience and knowledge of mild cognitive impairment (MCI) among Chinese family caregivers of individuals with MCI. The sample was recruited from memory clinics in Zhongnan Hospital in Wuhan, China. In-depth semi-structured interviews were used. Thirteen family members of individuals diagnosed with MCI participated in the study. Data analysis revealed three themes: 1) initial recognition of cognitive decline; 2) experience of the diagnosis of MCI; 3) perception of cognitive decline as a normal part of aging. While family members recognized the serious consequences of memory loss (e.g. getting lost), they would typically not take their family members to see a doctor until something specific triggered their access to the medical care system. The Chinese traditional perception of dementia as part of normal aging may serve to lessen the stigma of individuals with MCI, while the term "laonian chidai" which literally translates to "stupid, demented elderly" may exacerbate the stigma associated with individuals with MCI. It is suggested that family members' worries may be relieved by improving their access to accurate knowledge of the disease, community-based and institutional care services, and culturally appropriately words are needed for MCI.

Abstract

Nurse educators must meet the challenge of preparing a new generation of nurse leaders who can address the health care needs of an increasingly multicultural society. Institutional culture change that promotes inclusivity develops in response to an intentional embracement of diversity and is key to the success of any program initiatives. Providing resources for students can backfire if they experience the negative consequences of labeling, if incentives are distributed without thoughtful consideration of the related expectations, and if the advising system focuses on prescriptive, rather than developmental, principles. A deficit-thinking perspective that brands a student as at risk can undermine the goal of providing support. Faculty must engage in open discussions about labels, underlying assumptions about student aptitudes, and strategies for ensuring student success. Most importantly, faculty must actively solicit and seriously consider the students' accounts of their experiences and perspectives on changes that would make the climate more welcoming.

Abstract

As an increasing number of children and adolescents with psychiatric symptoms go unrecognized in our current healthcare system, the ability to identify and treat these issues in multiple healthcare settings has become vitally important. With access to primary care providers increasing and a shortage of child psychiatric providers, collaboration between psychiatric, pediatric and family advanced practice nurses is essential to improving care for this vulnerable population. Child and Adolescent Behavioral Health provides a practical reference to aid in this endeavour. Written and reviewed by over 70 nurse experts, it is a must-have reference for all practitioners caring for children and adolescents.

Abstract

Objectives To examine the relationship between cognitive function and self-reported oral health-related quality of life (HRQoL) in community-dwelling older adults. Design Cross-sectional. Setting Community in West Virginia. Participants Two hundred twenty-six community-dwelling older adults. Measurements Oral HRQoL was measured using the Geriatric Oral Health Assessment Index (GOHAI) (range 12-60), and cognitive function was assessed using a comprehensive neuropsychological test battery. Dental professionals performed oral health examinations. Results Participants with normal cognitive function had higher GOHAI total scores (mean 55.1), indicating better oral HRQoL, than participants with cognitive impairment without dementia (CIND) (mean 52.3) and mild dementia (mean 51.0). The difference remained significant after controlling for sociodemographic, health status, comorbidity, and clinical dental status covariates. Conclusion Oral HRQoL, as measured using the GOHAI, was better in participants with normal cognitive function than in those with CIND of mild dementia in the population studied.

Abstract

The growing number of individuals with comorbidities experiencing care transitions represents a challenge to the current health care system. A qualitative study of empirical literature, using the Dimensional Analysis approach, was conducted to elucidate the theoretical underpinnings of the phenomenon of individuals with comorbidities undergoing care transitions. The findings were arranged in a novel schematic demonstrating that the relationship among individual attributes, comorbidities, and care processes informed the individual's risk for adverse outcomes. This schematic is useful for future nursing research studies evaluating innovative programs implemented to improve health outcomes among vulnerable populations undergoing care transitions.

Abstract

We assessed the occurrence of 4 safety concerns among labor and delivery teams: dangerous shortcuts, missing competencies, disrespect, and performance problems. A total of 3282 participants completed surveys, and 92% of physicians (906 of 985), 93% of midwives (385 of 414), and 98% of nurses (1846 of 1884) observed at least 1 concern within the preceding year. A majority of respondents said these concerns undermined patient safety, harmed patients, or led them to seriously consider transferring or leaving their positions. Only 9% of physicians, 13% of midwives, and 13% of nurses shared their full concerns with the person involved. Organizational silence is evident within labor-and-delivery teams. Improvement will require multiple strategies, used at the personal, social, and structural levels.

Abstract

Consumption of foods high in sugar promotes insulin production, which has been linked to endometrial carcinogenesis. We evaluated the impact of dietary intake of sugary foods and beverages, as well as added sugar and total sugar on endometrial cancer risk in a population-based case-control study, including 424 cases and 398 controls. Participants completed an interview and food frequency questionnaire, and provided self-recorded waist and hip measurements. Women in the highest quartile of added sugar intake had significantly increased endometrial cancer risk (OR = 1.84, 95 % CI 1.16-2.92). Among women with waist-to-hip ratio ≥0.85, risk was significantly higher for the highest versus lowest tertile of added sugar intakes (OR = 2.50, 95 % CI 1.38-4.52). The association with added sugar also became stronger when analyses were restricted to never users of hormone replacement therapy (OR = 2.03; 95 % CI 1.27-3.26, for highest versus lowest tertile). There was little evidence of effect modification by body mass index or physical activity. Given the high prevalence of intake of sugary foods and drinks in Western populations, additional research is warranted to confirm our findings on endometrial cancer.

Abstract

Objective: The objective of this study is to evaluate the content validity of the Iberian Spanish version of the questionnaire The Practice Environment Scale of the Nursing Work Index (PES-NWI) by using the Content Validity Indexing (CVI). Methods: A descriptive cross-sectional observational study was conducted. The Spanish version of the questionnaire was translated from the American English instrument through forward and back translation processes. Experts evaluated the translated items through content validity indexing. Once the assessments were completed, CVI indicators were calculated: number of agreements, item Content Validity Index and overall content validity and modified kappa coefficient of the instrument. Results: The overall content validity of the instrument was 0.82. The average modified kappa coefficient of the items was 0.80, with a rating of 'excellent'. Only 4 of the items were rated as weak or poor. Conclusions: The study demonstrates that the content validity of the Spanish version of the PES-NWI is acceptable. Some results indicate that some items have cross-cultural applicability challenges that need to be addressed in future research studies. Use of the instrument in other Spanish language speaking countries should be taken with caution since some words may not reflect the language of the healthcare systems there.

Abstract

Objective:To investigate the incidence and risk factors associated with uncomplicated maternal sepsis and progression to severe sepsis in a large population-based birth cohort.Methods:This retrospective cohort study used linked hospital discharge and vital statistics records data for 1,622,474 live births in California during 2005-2007. Demographic and clinical factors were adjusted using multivariable logistic regression with robust standard errors.Results:1598 mothers developed sepsis; incidence of all sepsis was 10 per 10,000 live births (95% CI = 9.4-10.3). Women had significantly increased adjusted odds (aOR) of developing sepsis if they were older (25-34 years: aOR = 1.29; ≥35 years: aOR = 1.41), had ≤high-school education (aOR = 1.63), public/no-insurance (aOR = 1.22) or a cesarean section (primary: aOR = 1.99; repeat: aOR = 1.25). 791 women progressed to severe sepsis; incidence of severe sepsis was 4.9 per 10,000 live births (95% CI = 4.5-5.2). Women had significantly increased adjusted odds of progressing to severe sepsis if they were Black (aOR = 2.09), Asian (aOR = 1.59), Hispanic (aOR = 1.42), had public/no-insurance (aOR = 1.52), delivered in hospitals with <1,000 births/year (aOR = 1.93), were primiparous (aOR = 2.03), had a multiple birth (aOR = 3.5), diabetes (aOR = 1.47), or chronic hypertension (aOR = 8.51). Preeclampsia and postpartum hemorrhage were also significantly associated with progression to severe sepsis (aOR = 3.72; aOR = 4.18). For every cumulative factor, risk of uncomplicated sepsis increased by 25% (95% CI = 17.4-32.3) and risk of progression to severe sepsis/septic shock increased by 57% (95% CI = 40.8-74.4).Conclusions:The rate of severe sepsis was approximately twice the 1991-2003 national estimate. Risk factors identified are relevant to obstetric practice given their cumulative risk effect and the apparent increase in severe sepsis incidence.

Abstract

Purpose: To introduce current and emerging approaches that are being utilized in the field of genomics so the reader can conceptually evaluate the literature and appreciate how these approaches are advancing our understanding of health-related issues. Organizing Construct: Each approach is described and includes information related to how it is advancing research, its potential clinical utility, exemplars of current uses, challenges related to technologies used for these approaches, and when appropriate information related to understanding the evidence base for clinical utilization of each approach is provided. Web-based resources are included for the reader who would like more in-depth information and to provide opportunity to stay up to date with these approaches and their utility. Conclusions: The chosen approaches-genome sequencing, genome-wide association studies, epigenomics, and gene expression-are extremely valuable approaches for collecting research data to help us better understand the pathophysiology of a variety of health-related conditions, but they are also gaining in utility for clinical assessment and testing purposes. Clinical Relevance: Our increased understanding of the molecular underpinnings of disease will assist with better development of screening tests, diagnostic tests, tests that allow us to prognosticate, tests that allow for individualized treatments, and tests to facilitate post-treatment surveillance.

Abstract

Purpose: Depressive symptoms are common in cancer patients and their family caregivers (FCs). While these symptoms are characterized by substantial interindividual variability, the factors that predict this variability remain largely unknown. This study sought to confirm latent classes of oncology patients and FCs with distinct depressive symptom trajectories and to examine differences in phenotypic and genotypic characteristics among these classes. Method: Among 167 oncology outpatients with breast, prostate, lung, or brain cancer and 85 of their FCs, growth mixture modeling (GMM) was used to identify latent classes of individuals based on Center for Epidemiological Studies-Depression (CES-D) scores obtained prior to, during, and for four months following completion of radiation therapy. One hundred four single nucleotide polymorphisms (SNPs) and haplotypes in 15 candidate cytokine genes were interrogated for differences between the two largest latent classes. Multivariate logistic regression analyses assessed effects of phenotypic and genotypic characteristics on class membership. Results: Four latent classes were confirmed: Resilient (56.3%), Subsyndromal (32.5%), Delayed (5.2%), and Peak (6.0%). Participants who were younger, female, non-white, and who reported higher baseline trait and state anxiety were more likely to be in the Subsyndromal, Delayed, or Peak groups. Variation in three cytokine genes (i.e., interleukin 1 receptor 2 [IL1R2], IL10, tumor necrosis factor alpha [TNFA]), age, and performance status predicted membership in the Resilient versus Subsyndromal classes. Conclusions: Findings confirm the four latent classes of depressive symptom trajectories previously identified in a sample of breast cancer patients. Variations in cytokine genes may influence variability in depressive symptom trajectories.
