Abstract

Background: Diabetes technology has the potential to provide useful data for theory-based behavioral counseling. The aims of this study are to evaluate the feasibility, acceptability, and preliminary efficacy of a continuous glucose monitoring and problem-solving counseling intervention to change physical activity (PA) behavior in women with type 2 diabetes. Methods: Women (n=29) with type 2 diabetes were randomly assigned to one of two treatment conditions: continuous glucose counseling and problem-solving skills or continuous glucose monitoring counseling and general diabetes education. Feasibility data were obtained on intervention dose, implementation, and satisfaction. Preliminary efficacy data were collected at baseline and 12 weeks on the following measures: PA amount and intensity, diet, problem-solving skills, self-efficacy for PA, depression, hemogoloin A1c, weight, and blood pressure. Demographic and implementation variables were described using frequency distributions and summary statistics. Satisfaction data were analyzed using Wilcoxon rank. Differences between groups were analyzed using linear mixed-modeling. Results: Women were mostly white/non-Latina with a mean age of 53 years, a 6.5-year history of diabetes, and suboptimal glycemic control. Continuous glucose monitoring plus problem-solving group participants had significantly greater problem-solving skills and had greater, although not statistically significant, dietary adherence, moderate activity minutes, weight loss, and higher intervention satisfaction pre-to post-intervention than did participants in the continuous glucose monitoring plus education group. Conclusion: A continuous glucose monitoring plus problem-solving intervention was feasible and acceptable, and participants had greater problem-solving skills than continuous glucose monitoring plus education group participants.

Abstract

During the past 2 decades, life-course social-ecological frameworks have emerged across health, developmental, social, behavioral, and public health disciplines as useful models for explaining how health trajectories develop over an individual's lifetime and how this knowledge can guide and inform new approaches to clinical and public health practice, multilevel policies, and research. Viewed from this perspective, and with emphasis on global cardiovascular health promotion and prevention of cardiovascular disease (CVD), this article summarizes evidence on the early origins and progression of CVD processes across the life course of individuals and diverse populations. Current evidence-based guidelines for CVD prevention are summarized, and recommendations for future research are suggested.

Abstract

Aims. This paper is a report of a descriptive comparative pilot study of use of a method that simultaneously tests the content validity and quality of translation of English-to-Chinese translations of two patient satisfaction questionnaires: the La Monica-Oberst Patient Satisfaction Scale and Hospital Consumer Assessment of Healthcare Providers and Systems. Background. Patient satisfaction is an important indicator of the quality of healthcare services. In China, however, few good translations of patient satisfaction instruments sensitive to nursing services exist. Methods. The descriptive pilot study took place in 2009 and used content validity indexing techniques to evaluate the content, context and criterion relevance of a survey question. The expert raters were 10 nursing faculty and 10 patients who evaluated the two patient satisfaction questionnaires. The experts evaluated the relevance of each item on a scale of 1-4 and the research team compared their responses to choose the most appropriate. Only the nurse faculty experts, who were bilingual, evaluated the quality of the translation using a binary rating. Results. The 'Nurse Rater' relevance scores of the LaMonica-Oberst Patient Satisfaction Scale and the Hospital Consumer Assessment of Healthcare Providers and Systems were 0·96 and 0·95 respectively, whereas the patient's overall relevance scores were 0·89 and 0·95. A Mann-Whitney U-test demonstrated that results between the two groups were statistically significantly different (P=0·0135). Conclusions. Using content validity indexing simultaneously with translation processes was valuable for selecting and evaluating survey instruments in different contexts.

Abstract

Background: Most heart failure (HF) patients have other comorbid conditions. HF self-care requires medication and diet adherence, daily weight monitoring, and a thoughtful response to symptoms when they occur. Self-care is complicated when other chronic conditions have additional self-care requirements. The purpose of this study is to explore how comorbidity influences HF self-care. Methods: Using qualitative descriptive meta-analysis techniques, transcripts from 3 mixed methods studies (n = 99) were reexamined to yield themes about perceptions about HF and self-care and to explore the influence on HF self-care. The Charlson Comorbidity Index identified comorbid conditions. Results: The sample was 74% Caucasian, 66% male (mean age of 59.6 years ± 15 years). Fifty-three percent of the sample was New York Heart Association Class III. All had at least 1 other chronic condition. Narrative accounts revealed that adherence to diet, symptom monitoring, and differentiating symptoms from multiple conditions were the most challenging self-care skills. Emerging themes included 1) attitudes drive self-care prioritization and 2) fragmented self-care instruction leads to poor self-care integration and self-care skill deficits. Conclusions: Individuals with multiple chronic conditions are vulnerable to poor self-care. Research testing coaching interventions that integrate self-care requirements and focus on developing skill in self-care across multiple chronic conditions is needed.

Abstract

Objective: The findings from several studies suggest that palliative care patients with advanced cancer experience multiple symptoms, and that these symptoms may be related to demographic and clinical factors as well as to patient outcomes. However, no systematic review has summarized the findings from studies that assessed multiple symptoms, predictors, and outcomes in these patients. The purposes of this review, focused on palliative care patients with advanced cancer, are to: 1) describe the relationships among multiple symptoms; 2) describe the predictors of multiple symptoms; and 3) describe the relationships between multiple symptoms and patient outcomes. Method: Comprehensive literature searches were completed using the following databases: PubMed, Cumulative Index to Nursing and Allied Health Literature, and PsychInfo. The key words: cancer or advanced cancer or neoplasm, AND palliative care or terminal care or hospice or end-of-life, AND symptoms or multiple symptoms or symptom clusters were combined.Results: Twenty-two studies met the inclusion criteria and examined at least one of our purposes. The majority of these studies were descriptive and used one of four common symptom assessment scales. Fifty-six different signs and symptoms were evaluated across various dimensions (i.e., prevalence, severity, distress, frequency, control). Pain, dyspnea, and nausea were the only symptoms measured in all 22 studies. Relationships among concurrent symptoms were examined in nine studies. Relationships among symptoms and predictors (i.e., demographics, cancer type, healthcare delivery environment) were examined in seven studies. Relationships among symptoms and outcomes (i.e., functional status, psychological status, quality-of-life, survival time) were examined in 14 studies. Significant methodological variation was found among these studies.Significance of results: It is difficult to draw conclusions about the relationships among multiple symptoms, predictors, and outcomes due to the heterogeneity of these studies. Future research is needed to determine which symptoms and symptom dimensions to assess in order to better understand how multiple symptoms relate to each other as well to as predictors and outcomes in palliative care patients with advanced cancer.

Abstract

Purpose: The mission of the California Maternal Quality Care Collaborative is to eliminate preventable maternal death and injury and to promote equitable maternity care in California. This article describes California Maternal Quality Care Collaborative's (CMQCC's) statewide multistakeholder quality improvement initiative to improve readiness, recognition, response, and reporting of maternal hemorrhage at birth and details the essential role of nurses in its success. Project Design and Approach: In partnership with the State Department of Maternal, Child, and Adolescent Health, CMQCC identified maternal hemorrhage as a significant quality improvement opportunity. CMQCC organized a multidisciplinary, multistakeholder task force to develop a strategy for addressing obstetric (OB) hemorrhage. Project Description: The OB Hemorrhage Task Force, co-chaired by nurse and physician team leaders, identified four priorities for action and developed a comprehensive hemorrhage guideline. CMQCC is using a multilevel strategy to disseminate the guideline, including an open access toolkit, a minimal support-mentoring model, a county partnership model, and a 30-hospital learning collaborative. Clinical Implications: In participating hospitals, nurses have been the primary drivers in developing both general and massive hemorrhage policies and procedures, ensuring the availability of critical supplies, organizing team debriefing after a stage 2 (or greater) hemorrhage, hosting skills stations for measuring blood loss, and running obstetric (OB) hemorrhage drills. Each of these activities requires effort and leadership skill, even in hospitals where clinicians are convinced that these changes are needed. In some hospitals, the burden to convince physicians of the value of these new practices has rested primarily upon nurses. Thus, the statewide initiative in which nurse and physician leaders work together models the value of teamwork and provides a real-time demonstration of the potential for effective interdisciplinary collaboration to make a difference in the quality of care that can be achieved. Nurses provide significant leadership in multidisciplinary, multistakeholder quality projects in California. Ensuring that nurses have the opportunity to participate in formal leadership of these teams and are represented at all workgroup levels is critical to the overall initiative. Nurses brought key understanding of operational issues within and across departments, mobilized engagement across the state through the regional perinatal programs, and developed innovative approaches to solving clinical problems during implementation. Nursing leadership and integrated participation was especially critical in considering the needs of lower-resource settings, and was essential to the toolkit's enthusiastic adoption at the unit/service level in facilities across the state.

Abstract

This paper examines changes in the interval between first heroin smoking and onset of injection in a large, out-treatment sample of male heroin users in Hanoi, Vietnam (n = 1,115). Mean age at initiation of heroin use (smoking) was 18.4 and mean age of onset of heroin injection was 20.9 years. Full multivariate analysis indicates that the interval between first heroin use (smoking) and first heroin injection has been significantly attenuated among more recent heroin initiates (P = 0.0043), suggesting that heroin users in Vietnam may be at increased risk for exposure to HIV relatively soon after onset of heroin use, highlighting the need for behavioral interventions that target heroin smokers. Critical intervention goals include delaying the onset of injection and improved education about safer drug sharing and drug injection practices.

Abstract

Substance misusers are at risk for contracting HIV/AIDS, and substance user treatment programs (SUTPs)1 are uniquely situated to address their HIV-related needs. In New York State, some SUTPs have implemented a centralized model of substance user treatment and HIV care. We synthesize past literature and use data from semistructured interviews with SUTP staff, analyzed with qualitative software, to describe implementation barriers. These interviews were conducted in 2003-2004 at three SUTPs in Texas and New York as part of a study funded by the National Institutes of Health. With study limitations noted, main implications include a need for a combined medical-addiction treatment philosophy to facilitate multidisciplinary care.

Abstract

Our knowledge of pharmacogenetic variability in diverse populations is scarce, especially in sub-Saharan Africa. To bridge this gap in knowledge, we characterised population frequencies of clinically relevant pharmacogenetic traits in two distinct South African population groups. We genotyped 211 tagging single nucleotide polymorphisms (tagSNPs) in 12 genes that influence antiretroviral drug disposition, in 176 South African individuals belonging to two distinct population groups residing in the Western Cape: the Xhosa (n = 109) and Cape Mixed Ancestry (CMA) (n = 67) groups. The minor allele frequencies (MAFs) of eight tagSNPs in six genes (those encoding the ATP binding cassette sub-family B, member 1 [ABCB1], four members of the cytochrome P450 family [CYP2A7P1, CYP2C18, CYP3A4, CYP3A5] and UDP-glucuronosyltransferase 1 [UGT1A1]) were significantly different between the Xhosa and CMA populations (Bonferroni p < 0.05). Twentyseven haplotypes were inferred in four genes (CYP2C18, CYP3A4, the gene encoding solute carrier family 22 member 6 [SLC22A6] and UGT1A1) between the two South African populations. Characterising the Xhosa and CMA population frequencies of variant alleles important for drug transport and metabolism can help to establish the clinical relevance of pharmacogenetic testing in these populations.

Abstract

OBJECTIVES: To estimate risk factors for premature neonates not receiving antenatal steroids in a population-based cohort and to determine whether the gains of a quality-improvement collaborative project on antenatal steroid administration were sustained long-term. METHODS: Clinical data for premature neonates born in 2005-2007 were obtained from the California Perinatal Quality Care Collaborative, which collects data on more than 90% of neonatal admissions in California. Eligible neonates had a birth weight of less than 1,500 g or gestational age less than 34 weeks and were born at a Collaborative hospital. These data were linked to administrative data from California Vital Statistics. Sociodemographic and medical risk factors for not receiving antenatal steroids were determined. We also examined the effect of birth hospital participation in a previous quality-improvement collaborative project. A random effects logistic regression model was used to determine independent risk factors. RESULTS: Of 15,343 eligible neonates, 23.1% did not receive antenatal steroids in 2005-2007. Hispanic mothers (25.6%), mothers younger than age 20 (27.6%), and those without prenatal care (52.2%) were less likely to receive antenatal steroids. Mothers giving birth vaginally (26.8%) and mothers with a diagnosis of fetal distress (26.5%) were also less likely to receive antenatal steroids. Rupture of membranes before delivery and multiple gestations were associated with higher likelihood of antenatal steroid administration. Hospitals that participated in a quality-improvement collaborative in 1999-2000 had higher rates of antenatal steroid administration (85% compared with 69%, P<.001). CONCLUSION: A number of eligible mothers do not receive antenatal steroids. Quality-improvement initiatives to improve antenatal steroid administration could target specific high-risk groups.

Abstract

Background: Few studies have examined the association between self-reported sexual risk behaviors and biologic outcomes in human immunodeficiency virus (HIV)-1-seropositive African adults. Methods: We conducted a prospective cohort study in 898 HIV-1-seropositive women who reported engaging in transactional sex in Mombasa, Kenya. Primary outcome measures included detection of sperm in genital secretions, pregnancy, and sexually transmitted infections. Because 3 outcomes were evaluated, data are presented with odds ratios [OR] and 96.7% confidence intervals [CI] to reflect that we would reject a null hypothesis if a P-value was ≤0.033 (Simes' methodology). Results: During 2404 person-years of follow-up, self-reported unprotected intercourse was associated with significantly higher likelihood of detecting sperm in genital secretions (OR: 2.32, 96.7% CI: 1.93, 2.81), and pregnancy (OR: 2.78, 96.7% CI: 1.57, 4.92), but not with detection of sexually transmitted infections (OR: 1.20, 96.7% CI: 0.98, 1.48). At visits where women reported being sexually active, having >1 sex partner in the past week was associated with lower likelihood of detecting sperm in genital secretions (OR: 0.74, 96.7% CI: 0.56, 0.98). This association became nonsignificant after adjustment for reported condom use (adjusted OR: 0.81, 96.7% CI: 0.60, 1.08). Conclusions: Combining behavioral and biologic outcomes, which provide complementary information, is advantageous for understanding sexual risk behavior in populations at risk for transmitting HIV-1. The paradoxical relationship between higher numbers of sex partners and less frequent identification of sperm in genital secretions highlights the potential importance of context-specific behavior, such as condom use dependent on partner type, when evaluating sexual risk behavior.

Abstract

Aim: Endothelial lipase (EL) is a key enzyme in lipid metabolism, and a polymorphism in the EL gene may be a candidate for modulating lipid parameters in type 2 diabetic (T2D) patients. Methods: In 396 T2D patients (age: 59.5±10.7 years; BMI: 28.9±5.3kg/m2; HbA1c: 8.2±1.9%), the c.584C>T polymorphism (rs2000813, p.Thr111Ile) was studied in 225 men (frequency of c.584T: 0.351) and 171 women (frequency of c.584T: 0.304). Patients' metabolic parameters, and macrovascular and microvascular complications, were assessed at baseline and at follow-up (mean: 4.2 years). Results: Patients who were homozygous for the minor allele displayed modestly decreased low-density lipoprotein (LDL) cholesterol and raised apolipoprotein B at baseline, and raised systolic blood pressure and high-density lipoprotein (HDL) cholesterol on follow-up. Homozygosity for the minor allele was significantly associated with frequency of retinopathy (P=0.025), with TT homozygous patients more likely to have diabetic retinopathy (OR: 3.505; 95% CI: 1.491-8.239) both initially and at follow-up. Conclusion: The c.584C > T EL polymorphism is associated with a higher risk of diabetic retinopathy that could be linked to modifications in HDL-cholesterol metabolism and blood pressure levels.

Abstract

Although death rates from cardiovascular disease (CVD) have declined in recent years, it continues to be the leading cause of death for women in the United States. The risk factors for CVD are well established and include physical inactivity. According to the Centers for Disease Control, in 2008, 38% of women reported no physical activity. For many women who experience a cardiac event, their first opportunity to become physically active is through a formal cardiac rehabilitation (CR) program. Unfortunately, women often underutilize CR programs. The purpose of this integrative review was to examine the barriers to participation in a CR program among women with CVD.
