Abstract

Palliative care involvement with patients with advanced disease has demonstrated significant cost savings at end of life (EOL). These financial benefits are largely due to improved EOL decision making. Assisting patients and families to examine their values and determine their preferences makes it possible to match patient goals with appropriate care. Often, comfort-oriented care is favored, avoiding the costs of medically aggressive, often futile, technology-driven interventions. Community-based EOL care discussions would demonstrate increased cost reductions while facilitating significant patient and family satisfaction with care.

Abstract

Background: Clinicians use CA125, a tumor-associated antigen, primarily to monitor epithelial ovarian cancer. However, CA125 lacks the sensitivity and specificity necessary for population-based screening in healthy women. The purpose of this study was to determine if serum concentrations of CA125 differed across the three phases of the menstrual cycle in healthy, premenopausal women using two commercially available assays. Methods: Healthy, Caucasian women between the ages of 18 and 39 were enrolled using strict criteria to exclude factors known to contribute to CA125 fluctuations. Menstrual cycle regularity was determined using calendars maintained by participants for 3 months. After cycle regularity was established, blood was drawn at three time points for CA125 determination using two commercial assays (i.e., Siemens and Panomics). Results: Regardless of the assay used, CA125 values were highest during menses. The CA125 values decreased 0.2 U/ml per day from menses to the end of the same cycle, which resulted in a net decrease of 5.8 U/ml across the cycle. Conclusions: The two commercial assays for CA125 determination demonstrated good concordance in terms of reference ranges regardless of epitope differences. While CA125 levels changed over the course of the menstrual cycle, these changes may not be clinically significant in healthy women. This study is the first to control for factors known to contribute to CA125 elevations; to quantify a decrease in CA125 levels across the menstrual cycle; and to confirm concordance in the relative decreases in serum CA125 levels across the menstrual cycle between two frequently used commercial assays.

Abstract

Purpose: This study examined the social and contextual factors associated with continued high risk sexual behaviors among male-to-female transgender (MTFTG) adolescents living with HIV/AIDS. The study is part of a larger qualitative study of 59 racial/ethnic minority adolescents living with HIV/AIDS. Methods: In-depth focused interviews were conducted with five MTFTG adolescents (16-24 years) living with HIV. Content analysis was conducted to identify themes related to continued sexual risk behaviors. Results: Four out of five of MTFTG adolescents reported inconsistent condom use since their HIV diagnosis. Transgender stigma contributed to financial vulnerability leading to the adoption of sex work to support themselves. Sex and drugs were used to manage transgender stigma and sexual risk-taking with sex work partners was influenced by financial vulnerability. Conclusions: MTFTG adolescents with HIV have unique psychosocial needs related to transgender stigma and structural needs to decrease financial vulnerability that contribute to risky sexual behavior.

Abstract

Purpose: The purpose of this article is to explain the evolution of a situation-specific theory developed to enhance understanding of health-related behaviors of Korean Americans (KAs) who have or are at risk for a chronic hepatitis B virus (HBV) infection. Organizing Construct: The situation-specific theory evolved from an integration of the Network Episode Model, studies of health-related behaviors of people with HBV infection, and our studies of and practice experiences with Asian American individuals with HBV infection. Findings: The major concepts of the theory are sociocultural context, social network, individual-level factors, illness experience, and health-related behaviors. Conclusions: The major propositions of the theory are that sociocultural context, social network, and individual-level factors influence the illness experience, and that sociocultural context, social network, individual-level factors, and the illness experience influence health-related behaviors of KAs who have or are at risk for HBV infection. Clinical Relevance: This situation-specific theory represents a translation of abstract concepts into clinical reality. The theory is an explanation of correlates of health-related HBV behaviors of KAs. The next step is to develop and test the effectiveness of a nursing intervention designed to promote behaviors that will enhance the health of KAs who have or are at risk for HBV infection, and that takes into account sociocultural context, social network, individual-level factors, and illness experience.

Abstract

Objectives - Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in children in the United States. Although changes in diet are often recommended to improve NAFLD, little is known regarding diet influence on histologic features of the disease. Methods - This was a prospective, cross-sectional registry based study. Children (n=149) enrolled in the multi-center NASH Clinical Research Network had demographic, anthropometric, clinical, laboratory and histology data obtained, including the Block Brief Food Questionnaire. Subjects were grouped by presence or absence of steatohepatitis and grades of histologic features according to NASH-CRN criteria. Results - No significant differences were found between children with steatosis compared to steatohepatitis for fraction of calories from fat, carbohydrates, and protein. Sugar sweetened beverage consumption was low and did not correlate with histologic features, although uric acid, a surrogate marker for fructose intake, was significantly increased in those with definite NASH (p=. 008). For all groups, Vitamin E consumption was insufficient compared to the recommended daily allowance. Median consumption of Vitamin E was lower in children with higher grade of steatosis (8.4 vs 6.1 vs 6.9 for grade I, II and III respectively, p = .05). Those consuming less Vitamin C had increased ballooning degeneration (p = 0.05). Conclusions - Children with NAFLD have a diet that is insufficient in Vitamin E and this may contribute to the pathophysiology of NAFLD. In children with NAFLD, reported sugar sweetened beverage consumption is low; however uric acid, which may reflect total fructose consumption, was significantly associated with NASH and should be further evaluated.

Abstract

Objective: To describe the systematic language translation and cross-cultural evaluation process that assessed the relevance of the Hospital Consumer Assessment of Healthcare Providers and Systems survey in five European countries prior to national data collection efforts. Design: An approach involving a systematic translation process, expert review by experienced researchers and a review by 'patient' experts involving the use of content validity indexing techniques with chance correction. Setting: Five European countries where Dutch, Finnish, French, German, Greek, Italian and Polish are spoken. Participants: 'Patient' experts who had recently experienced a hospitalization in the participating country. Main OutcomeMeasure(s): Content validity indexing with chance correction adjustment providing a quantifiable measure that evaluates the conceptual, contextual, content, semantic and technical equivalence of the instrument in relationship to the patient care experience. Results: All translations except two received 'excellent' ratings and no significant differences existed between scores for languages spoken in more than one country. Patient raters across all countries expressed different concerns about some of the demographic questions and their relevance for evaluating patient satisfaction. Removing demographic questions from the evaluation produced a significant improvement in the scale-level scores (P = .018). The cross-cultural evaluation process suggested that translations and content of the patient satisfaction survey were relevant across countries and languages. Conclusions: The Hospital Consumer Assessment of Healthcare Providers and Systems survey is relevant to some European hospital systems and has the potential to produce internationally comparable patient satisfaction scores.

Abstract

While patients with advanced cancer experience a wide range of symptoms, no work has been done to determine an optimal cutpoint for a low versus a high number of symptoms. Analytic approaches that established clinically meaningful cutpoints for the severity of cancer pain and fatigue provided the foundation for this study. The purpose of this study was to determine the optimal cutpoint for low and high numbers of symptoms using a range of potential cutpoints and to determine if those cutpoints distinguished between the two symptom groups on demographic and clinical characteristics and depression, anxiety, and quality of life (QOL). Patients with advanced cancer (n=110) completed a symptom assessment scale, and measures of depression, anxiety, and QOL. Combinations of cutpoints were tested to yield one-and two-cutpoint solutions. Using analysis of variance for QOL scores, the F-ratio that indicated the highest between-group difference was determined to be the optimal cutpoint between low and high number of symptoms. A cutpoint of ≤12 symptoms (i.e., 0-12 is low, 13-32 is high) was the optimal cutpoint for total number of symptoms. Significant differences in depression, anxiety, and QOL scores validated this cutpoint. Psychological symptoms had higher occurrence rates in the high symptom group. Findings suggest that a threshold exists between a low and a high number of symptoms in patients with advanced cancer. Psychological symptoms were significantly different between patients in the low versus high symptom groups and may play an important role in QOL outcomes in patients with advanced cancer.

Abstract

In the United States, Blacks are disproportionately impacted by HIV/AIDS. Sexual networks and concurrent relationships have emerged as important contributors to the heterosexual transmission of HIV. To date, Africa is the only continent where an understanding of the impact of sexual concurrency has been conveyed in HIV prevention messaging. This project was developed by researchers and members of the Seattle, Washington, African American and African-Born communities, using the principles of community-based participatory research (CBPR). Interest in developing concurrency messaging came from the community and resulted in the successful submission of a community-academic partnership proposal to develop and disseminate HIV prevention messaging around concurrency. The authors describe (a) the development of concurrency messaging through the integration of collected formative data and findings from the scientific literature; (b) the process of disseminating the message in the local Black community; and (c) important factors to consider in the development of similar campaigns.

Abstract

This article reports and discusses how quantitative (physiological and behavioral) and qualitative methods are being combined in an open-label pilot feasibility study. The study evaluates safety, tolerability, and acceptability of a protocol to treat depression in HIV-infected individuals, using a 2-week block of transcranial direct current stimulation (tDCS) over the dorsolateral prefrontal cortex. Major depressive disorder (MDD) is the second most prevalent psychiatric disorder after substance abuse among HIV-positive adults, and novel antidepressant treatments are needed for this vulnerable population. The authors describe the challenges and contributions derived from different research perspectives and methodological approaches and provide a philosophical framework for combining quantitative and qualitative measurements for a fuller examination of the disorder. Four methodological points are presented: (1) the value of combining quantitative and qualitative approaches; (2) the need for context-specific measures when studying patients with medical and psychiatric comorbidities; (3) the importance of research designs that integrate physiological, behavioral, and qualitative approaches when evaluating novel treatments; and (4) the need to explore the relationships between biomarkers, clinical symptom assessments, patient self-evaluations, and patient experiences when developing new, patient-centered protocols. The authors conclude that the complexity of studying novel treatments in complex and new patient populations requires complex research designs to capture the richness of data that inform translational research.

Abstract

Objectives: This study examined patient and dental provider experiences during the periodontal visit of diabetes screening approaches involving the collection of gingival crevicular blood (GCB) and finger stick blood (FSB) for haemoglobin A1c (HbA1c) testing. Methods:At a large, urban, US periodontics and implant clinic, FSB samples from 120 patients and GCB samples from 102 of these patients were collected on special blood collection cards and sent to a laboratory for HbA1c testing, with test results sent to the patients from the laboratory. Quantitative and qualitative data from patients and qualitative data from providers were collected and analysed. Results:Quantitative and qualitative data support the feasibility and acceptability of the approaches described. Themes that arose from the interviews with providers and patients include 'a good chance to check', 'patient choice', 'FSB versus GCB testing' and 'a new way of interacting and viewing the dental visit'. Conclusions:Periodontal patients and dental providers believe that the dental visit is an opportune site for diabetes screening and generally prefer GCB to FSB collection. HbA1c testing is well tolerated, convenient and acceptable to patients, and GCB testing reduces time and liability obstacles for dental providers to conduct diabetes screening.

Abstract

Type 2 diabetes (T2D) is a growing national health problem affecting 35% of adults ≥20 years of age in the United States. Recently, diabetes has been categorized as an inflammatory disease, sharing many of the adverse outcomes as those reported from cardiovascular disease. Medical nutrition therapy is recommended for the treatment of diabetes; however, these recommendations have not been updated to target the inflammatory component, which can be affected by diet and lifestyle. To assess the current state of evidence for which dietary programs contain the most anti-inflammatory and glycemic control properties for patients with T2D, we conducted an integrative review of the literature. A comprehensive search of the PubMed, CINAHL, Scopus, and Web of Science databases from January 2000 to May 2012 yielded 786 articles. The final 16 studies met the selection criteria including randomized control trials, quasiexperimental, or cross-sectional studies that compared varying diets and measured inflammatory markers. The Mediterranean and DASH diets along with several low-fat diets were associated with lower inflammatory markers. The Mediterranean diet demonstrated the most clinically significant reduction in glycosylated hemoglobin (HbA 1c). Information on best dietary guidelines for inflammation and glycemic control in individuals with T2D is lacking. Continued research is warranted.

Abstract

The hypothesis is that fiber protects against colorectal cancer because of various biologic properties. Although several human studies have examined the relationship between fiber and colorectal carcinogenesis, the association remains unclear. This review evaluates key epidemiologic research in large populations conducted since 2003. With a combined analysis of 9 studies, results are mixed. Four studies show a statistically significant reduced risk of developing colorectal cancer with increased dietary fiber intake, and 5 studies show no association. On the basis of these equivocal findings, it cannot be concluded that a protective association exists between increased dietary fiber intake and reduced colorectal cancer risk.

Abstract

A survey was administered to male university students who tested positive for high-risk human papillomavirus. Disclosure was more likely in men with fewer partners, in main partnerships, and in longer partnerships. Disclosure was associated with discussing the Pap test/human papillomavirus vaccine with female partners and not associated with a worsening relationship.

Abstract

Objectives: This study examined edentulism trends among adults aged 50 and above in five ethnic groups in the United States: Asians, African Americans, Hispanics, Native Americans, and non-Hispanic Caucasians. Methods: Data came from the National Health Interview Surveys between 1999 and 2008. Respondents included 616 Native Americans, 2,666 Asians, 15,295 African Americans, 13,068 Hispanics, and 86,755 Caucasians. Results: In 2008, Native Americans had the highest predicated rate of edentulism (23.98%), followed by African Americans (19.39%), Caucasians (16.90%), Asians (14.22%), and Hispanics (14.18%). Overall, there was a significant downward trend in edentulism rates between 1999 and 2008 (OR = 0.97, 95% CI: 0.96, 0.98). However, compared with Caucasians, Native Americans showed a significantly less decline of edentulism during this period (OR = 1.10, 95% CI: 1.02, 1.19). Conclusions: While there was a downward trend in edentulism between 1999 and 2008, significant variations existed across racial/ethnic groups. Innovative public health programs and services are essential to prevent oral health diseases and conditions for minority populations who lack access to adequate dental care. Additionally, given the increasing numbers of adults retaining their natural teeth, interventions designed to assist individuals in maintaining healthy teeth becomes more critical.

Abstract

Despite wide disparities of political support, material resources, and systems of initial education, there exists an increasing global recognition that the level of nursing education has a close relationship with access to and quality of care. Still, individual nations also maintain alternative ways of educating nurses that are rooted in strong traditions. This paper explores the systems in China and Egypt. These countries have important differences. Education in China, for example, has been more heavily influenced by models from the United States, whereas Egypt has looked to those from Britain and France. Most striking, however, is what they now share. Both countries' systems of nursing education are now clearly located in an increasingly global world of health, and health care that recognizes that a more educated nursing workforce remains the critical component of any initiative to better meet health care needs.

Abstract

Background: Throughout the illness trajectory, women with breast cancer experience issues that are related to physical, emotional, and social adjustment. Despite a general consensus that state-of-the-art treatment for breast cancer should include educational and counseling interventions to reduce illness or treatment-related symptoms, there are few prospective, theoretically based, phase-specific randomized, controlled trials that have evaluated the effectiveness of such interventions in promoting adjustment. Purpose: The aim of this study is to examine the physical, emotional, and social adjustment of women with early-stage breast cancer who received psychoeducation by videotapes, telephone counseling, or psychoeducation plus telephone counseling as interventions that address the specific needs of women during the diagnostic, postsurgery, adjuvant therapy, and ongoing recovery phases of breast cancer. Design: Primary data from a randomized controlled clinical trial. Setting: Three major medical centers and one community hospital in New York City. Methods: A total of 249 patients were randomly assigned to either the control group receiving usual care or to one of the three intervention groups. The interventions were administered at the diagnostic, postsurgery, adjuvant therapy, and ongoing recovery phases. Analyses were based on a mixed model analysis of variance. Main Research Variables and Measurement: Physical adjustment was measured by the side effects incidence and severity subscales of the Breast Cancer Treatment Response Inventory (BCTRI) and the overall health status score of the Self-Rated Health Subscale of the Multilevel Assessment Instrument. Emotional adjustment was measured using the psychological well-being subscale of the Profile of Adaptation to Life Clinical Scale and the side effect distress subscale of BCTRI. Social adjustment was measured by the domestic, vocational, and social environments subscales of the Psychosocial Adjustment to Illness Scale. Findings: Patients in all groups showed improvement over time in overall health, psychological well-being, and social adjustment. There were no significant group differences in physical adjustment, as measured by side effect incidence, severity, or overall health. There was poorer emotional adjustment over time in the usual care (control) group as compared to the intervention groups on the measure of side effect distress. For the telephone counseling group, there was a marked decline in psychological well-being from the adjuvant therapy phase through the ongoing recovery phase. There were no significant group differences in the dimensions of social adjustment. Conclusion: The longitudinal design of this study has captured the dynamic process of adjustment to breast cancer, which in some aspects and at various phases has been different for the control and intervention groups. Although patients who received the study interventions improved in adjustment, the overall conclusion regarding physical, emotional, and social adjustment is that usual care, which was the standard of care for women in both the usual care (control) and intervention groups, supported their adjustment to breast cancer, with or without additional interventions. Implications for Nursing: The results are important to evidence-based practice and the determination of the efficacy and cost-effectiveness of interventions in improving patient outcomes. There is a need to further examine adjustment issues that continue during the ongoing recovery phase. Key Points: Psychoeducation by videotapes and telephone counseling decreased side effect distress and side effect severity and increased psychological well-being during the adjuvant therapy phase. All patients in the control and intervention groups improved in adjustment. Adjustment issues are still present in the ongoing recovery phase.

Abstract

Objective: There is a need to build the ranks of health care professionals engaged in substance abuse (SA)-focused clinical research. The authors simultaneously developed and evaluated SARET, the Substance Abuse Research Education and Training program. The fundamental goal of this interprofessional program is to stimulate medical, dental, and nursing student interest and experience in SA research. Evaluation aims to understand program feasibility and acceptability and to assess short-term impact. Methods: SARET comprises 2 main components: stipend-supported research mentorships and a Web-based module series, consisting of 6, interactive, multimedia modules addressing core SA research topics, delivered via course curricula and in the research mentorships. Authors assessed program feasibility and impact on student interestin conducting SA research by tracking participation and conducting participant focus groups and online surveys. Results: Thirty early health care professional students completed mentorships (25 summer, 5 yearlong) and 1324 completed at least 1 Web-module. SARET was considered attractive for the opportunity to conduct clinically oriented research and to work with health care professionals across disciplines. Mentorship students reported positive impact on their vision of SA-related clinical care, more positive attitudes about research, and, in some cases, change in career plans. Web-based modules were associated with enhanced interest in SA (35% increase, P = 0.005, in those somewhat/very interested for neurobiology module) and SA research (+38%, P < 0.001 for activation, +45%, P < 0.001 for personal impact, +7%, P = 0.089 for neurobiology). Conclusions: The SARET program stimulates SA clinical and research interest among students of nursing, medicine, and dentistry and may lend itself to dissemination.
