Abstract

Objectives. We examined the mechanisms by which living in a disadvantaged minority community influences smoking and illegal cigarette sale and purchasing behaviors after a large cigarette tax increase. Methods. Data were collected from 14 focus groups (n=104) that were conducted during the spring of 2003 among Blacks aged 18 years and older living in New York City. Results. A large tax increase led to what focus group participants described as a pervasive illegal cigarette market in a low-income minority community. Perceived pro-smoking community norms, a stressful social and economic environment, and the availability of illegal cigarettes worked together to reinforce smoking and undermine cessation. Conclusions. Although interest in quitting was high, bootleggers created an environment in which reduced-price cigarettes were easier to access than cessation services. This activity continues to undermine the public health goals of the tax increase.

Abstract

Key informant interviews, in-depth interviews and focus groups were conducted to examine ways in which social context influenced the behavior of Brazilian, Colombian and Dominican men who have sex with men. First, we investigated how the social context in the home country affected motivation for migration. Findings suggest that Latino men who have sex with men frequently reported coming to the USA to escape homo-negativity and to achieve greater sexual freedom. The study also examined how the social context encountered in the early years after migration shaped sexual behavior and risk. A majority of the participants reported easy access to sex partners and frequent sexual encounters. The anonymity of living in a gay epicentre such as New York City, often without social connections from the past, was experienced as liberating and conducive to sexual exploration. Moreover, sex in public venues, such as parks and sex cabins, was readily available to those who do not speak English. The tendency to engage in high levels of sexual activity during the early period after arrival in New York City was particularly evident among younger men. Implications for future programme development are discussed alongside prevention efforts targeting migrants during this critical period.

Abstract

Although the concept of the coagulation cascade represented a significant advance in the understanding of coagulation and served for many years as a useful model, more recent clinical and experimental observations demonstrate that the cascade/waterfall hypothesis does not fully and completely reflect the events of hemostasis in vivo. The goal of this article is to review the evolution of the theories of coagulation and their proposed models to serve as a tool when reviewing the research and practice literature that was published in the context of these different theories over time.

Abstract

The validity of baseline dietary intake data in women participating in a culturally competent intervention study for black women with type 2 diabetes was assessed. The relationship of sociodemographic and physiologic factors with underreporting of dietary intake was determined. Criterion validity of dietary intake, which had been assessed using the Nutritionist Five Collection Form, a combination of a standard 2-day dietary recall and a modified, culturally appropriate food frequency questionnaire, was determined. Data were analyzed using First Data Bank Nutritionist Five (version 2.3, 2000, First Data Bank, San Bruno, CA) software. Validation of baseline dietary data in 109 women was performed by calculating the ratio of energy intake to resting metabolic rate. χ2 and t tests were used to assess relationships between underreporting and sociodemographic and physiologic factors. Mean ratio of energy intake to resting metabolic rate was 1.46 (±0.4). Using a lower limit of 1.35, the prevalence of underreporting was 46.8%. Underreporting was significantly associated with body mass index (P≤0.001) and waist circumference (P<0.001). Use of this combined dietary recall and modified food frequency questionnaire might, therefore, provide more accurate dietary assessment in this population. Additional modification and validity testing is warranted in this and other populations.

Abstract

Background: Financial constraints and other forces affecting health care in many countries have led to nurses implicitly limiting their care in some instances. In the absence of an accepted definition and theoretical framework of implicit rationing of nursing care, a framework and the Basel Extent of Rationing of Nursing Care (BERNCA) instrument were developed. This instrument was used in the Swiss part of the International Hospital Outcome Study, in which implicit rationing of nursing care was studied. Objective: To examine the validity and reliability of the newly developed BERNCA instrument. Methods: Psychometric analysis was performed on data from 957 nurses in five Swiss acute care hospitals enrolled in a larger hospital organization study. An explanatory factor analysis with varimax rotation was used to investigate the instrument's internal structure, Spearman correlations were used to test relationships between implicit rationing and two related concepts, and Cronbach's alpha and interitem correlations were used to test the reliability of the scale. Results: Expert feedback confirmed that the BERNCA covered the implicit rationing of nursing care domain adequately and that its questions were fully comprehensible. The single-factor solution confirmed the instrument's unidimensional internal structure. A moderate to strong correlation in the expected direction was found between the BERNCA implicit rationing data and the quality of the nurse work environment as measured by the Nursing Work Index-Revised, particularly the perceived adequacy of nursing resources, although a significant but low correlation was also shown with patient-to-nurse ratios. Cronbach's alphas (.93) and interitem correlations indicated internal consistency and homogeneity. Discussion: Initial evidence of the validity and reliability of the BERNCA instrument was provided.

Abstract

Using data collected from 1,906 RNs from Metropolitan Statistical Areas in 29 states, the purpose of this study was to examine the characteristics and work attitudes of older RNs compared to RNs less than age 50 at two time periods, and compare among the older RNs those who are working in nursing, working outside nursing, and not working. Older RNs reported more distributive justice (fairness of rewards), work group cohesion, and supervisory support and less organizational constraint, and quantitative workload than younger RNs. Overall, older RNs were more satisfied, had greater organizational commitment, and had less desire to quit than younger RNs. There were no significant differences between older and younger RNs for autonomy, mentor support, or variety. Strategic efforts by employers and government could be used to retain older workers, attract RNs working in nonnursing settings back into nursing, and recruit retired RNs into the nursing workforce.

Abstract

BACKGROUND: Self-care is an integral component of successful heart failure (HF) management. Engaging patients in self-care can be challenging. METHODS: Fifteen patients with HF enrolled during hospitalization received a motivational intervention designed to improve HF self-care. A mixed method, pretest posttest design was used to evaluate the proportion of patients in whom the intervention was beneficial and the mechanism of effectiveness. Participants received, on average, 3.0 ± 1.5 home visits (median 3, mode 3, range 1-6) over a three-month period from an advanced practice nurse trained in motivational interviewing and family counseling. Quantitative and qualitative data were used to judge individual patients in whom the intervention produced a clinically significant improvement in HF self-care. Audiotaped intervention sessions were analyzed using qualitative methods to assess the mechanism of intervention effectiveness. RESULTS: Congruence between quantitative and qualitative judgments of improved self-care revealed that 71.4% of participants improved in self-care after receiving the intervention. Analysis of transcribed intervention sessions revealed themes of 1) communication (reflective listening, empathy); 2) making it fit (acknowledging cultural beliefs, overcoming barriers and constraints, negotiating an action plan); and, 3) bridging the transition from hospital to home (providing information, building skills, activating support resources). CONCLUSION: An intervention that incorporates the core elements of motivational interviewing may be effective in improving HF self-care, but further research is needed.

Abstract

This article provides an introduction to the field of art therapy and the potential it can offer to address the emotional needs of the frail elderly. Two case studies are discussed, and examples of artwork are provided. The case studies and artwork were created under the guidance of an art therapist at a Program of All-Inclusive Care for the Elderly (PACE) site in an urban African American community. This article explores how art making addresses the specific developmental tasks of the elderly in a culturally competent manner. Included are practical considerations in the choice of art media and directives for working with elderly clients, as well as resources for further information on the use of art in therapy.

Abstract

Objective: To evaluate the relationship between dietary lutein plus zeaxanthin and intermediate age-related macular degeneration (AMD). Design: Women aged 50 to 79 years in Iowa, Wisconsin, and Oregon with intake of lutein plus zeaxanthin above the 78th (high) and below the 28th (low) percentiles at baseline in the Women's Health Initiative Observational Study were recruited 4 to 7 years later into the Carotenoids in Age-Related Eye Disease Study (CAREDS), when the presence of AMD was determined by fundus photographs. Logistic regression analyses examined the prevalence of AMD in 1787 CAREDS participants, after accounting for potential covariates. Results: The prevalence of intermediate AMD was not statistically different between the high and low lutein plus zeaxanthin intake recruitment groups after adjusting for age (odds ratio, 0.96; 95% confidence interval, 0.75-1.23). Limiting analyses to women younger than 75 years with stable intake of lutein plus zeaxanthin, without a history of chronic diseases that are often associated with diet changes, substantially lowered odds ratios (0.57; 95% confidence interval, 0.34-0.95). Exploratory analyses of advanced AMD in 34 participants resulted in protective, but statistically nonsignificant, associations in the overall sample and in women younger than 75 years. Conclusion: Diets rich in lutein plus zeaxanthin may protect against intermediate AMD in healthy women younger than 75 years.

Abstract

Four of the five John A. Hartford Foundation Centers of Geriatric Nursing Excellence (HCGNEs) have been involved in efforts designed to improve the quality of nursing care to older adults through evidence-based Best Practice Initiatives. This article describes the important role these initiatives play in building academic geriatric nursing capacity. Building on the work of other nurse researchers, these projects attend to organizational and individual aspects of change theory, the scientific basis for practice innovations, and the role of expert consultation to support change. Best practice examples from the HCGNE demonstrate how the science involved in translating research into gerontological nursing practice has evolved, creating important educational opportunities for nursing students at all levels. In order to build academic geriatric nursing capacity, it is essential that schools of nursing help undergraduate and advanced practice nursing students develop an appreciation for how research and education can improve the care of older adults.
