Non-Adherence in Patients on Peritoneal Dialysis: A Systematic Review

Background: It has been increasingly recognized that non-adherence is an important factor that determines the outcome of peritoneal dialysis (PD) therapy. There is therefore a need to establish the levels of non-adherence to different aspects of the PD regimen (dialysis procedures, medications, and dietary/fluid restrictions). Methods: A systematic review of peer-reviewed literature was performed in PubMed, PsycINFO and CINAHL databases using PRISMA guidelines in May 2013. Publications on non-adherence in PD were selected by two reviewers independently according to predefined inclusion and exclusion criteria. Relevant data on patient characteristics, measures, rates and factors associated with non-adherence were extracted. The quality of studies was also evaluated independently by two reviewers according to a revised version of the Effective Public Health Practice Project assessment tool. Results: The search retrieved 204 studies, of which a total of 25 studies met inclusion criteria. Reported rates of nonadherence varied across studies: 2.6 1353% for dialysis exchanges, 3.9 1385% for medication, and 14.4 1367% for diet/fluid restrictions. Methodological differences in measurement and definition of non-adherence underlie the observed variation. Factors associated with non-adherence that showed a degree of consistency were mostly socio-demographical, such as age, employment status, ethnicity, sex, and time period on PD treatment. Conclusion: Non-adherence to different dimensions of the dialysis regimen appears to be prevalent in PD patients. There is a need for further, high-quality research to explore these factors in more detail, with the aim of informing intervention designs to facilitate adherence in this patient populatio

Tai Chi on psychological well-being: systematic review and meta-analysis

<p>Abstract</p> <p>Background</p> <p>Physical activity and exercise appear to improve psychological health. However, the quantitative effects of Tai Chi on psychological well-being have rarely been examined. We systematically reviewed the effects of Tai Chi on stress, anxiety, depression and mood disturbance in eastern and western populations.</p> <p>Methods</p> <p>Eight English and 3 Chinese databases were searched through March 2009. Randomized controlled trials, non-randomized controlled studies and observational studies reporting at least 1 psychological health outcome were examined. Data were extracted and verified by 2 reviewers. The randomized trials in each subcategory of health outcomes were meta-analyzed using a random-effects model. The quality of each study was assessed.</p> <p>Results</p> <p>Forty studies totaling 3817 subjects were identified. Approximately 29 psychological measurements were assessed. Twenty-one of 33 randomized and nonrandomized trials reported that 1 hour to 1 year of regular Tai Chi significantly increased psychological well-being including reduction of stress (effect size [ES], 0.66; 95% confidence interval [CI], 0.23 to 1.09), anxiety (ES, 0.66; 95% CI, 0.29 to 1.03), and depression (ES, 0.56; 95% CI, 0.31 to 0.80), and enhanced mood (ES, 0.45; 95% CI, 0.20 to 0.69) in community-dwelling healthy participants and in patients with chronic conditions. Seven observational studies with relatively large sample sizes reinforced the beneficial association between Tai Chi practice and psychological health.</p> <p>Conclusions</p> <p>Tai Chi appears to be associated with improvements in psychological well-being including reduced stress, anxiety, depression and mood disturbance, and increased self-esteem. Definitive conclusions were limited due to variation in designs, comparisons, heterogeneous outcomes and inadequate controls. High-quality, well-controlled, longer randomized trials are needed to better inform clinical decisions.</p

Design and rationale of a randomized controlled trial of melatonin supplementation in men and women with the metabolic syndrome

Paul D Terry,1 Abhinav Goyal,2,3 Lawrence S Phillips,3 Hillary M Superak,4 Michael H Kutner4 1Departments of Public Health and Surgery, University of Tennessee, Knoxville, TN, 2Department of Epidemiology, Emory Rollins School of Public Health, 3Department of Medicine, Emory School of Medicine, 4Department of Biostatistics and Bioinformatics, Emory Rollins School of Public Health, Atlanta, GA, USA Background: The metabolic syndrome is a constellation of interrelated metabolic risk factors that appear to increase the risk of atherosclerotic cardiovascular disease, type 2 diabetes mellitus, and possibly some cancers. Animal studies and observational clinical data in humans suggest that supplemental melatonin may ameliorate a number of components of the metabolic syndrome, including elevated glucose, elevated blood pressure, dyslipidemia, and obesity. The primary objective of this clinical trial was to determine the feasibility, efficacy, and safety of melatonin supplementation in men and women with the metabolic syndrome. Methods: Thirty-nine men and women of mixed race/ethnicity were enrolled into a randomized, double-blind, placebo-controlled clinical trial with two arms: placebo for 10 weeks followed by melatonin for 10 weeks, or vice versa, with an interval 6-week washout period, in a crossover trial design. Outcome measures include metabolic syndrome components (blood pressure, glucose, triglycerides, high-density lipoprotein cholesterol, waist circumference), oxidative stress, and inflammation biomarkers. These biomarkers, along with sleep duration and quality and pretreatment endogenous melatonin levels, were measured to explore possible underlying biologic mechanisms. Discussion: This trial will provide knowledge of the effects of melatonin in metabolic syndrome subjects, and lay the groundwork for future clinical trials of melatonin in metabolic syndrome subjects. Keywords: melatonin, metabolic syndrome, diabetes, blood pressure, slee

Effect of Spanish Interpretation Method on Patient Satisfaction in an Urban Walk-in Clinic

OBJECTIVE: To examine the effect of Spanish interpretation method on satisfaction with care. DESIGN: Self-administered post-visit questionnaire. SETTING: Urban, university-affiliated walk-in clinic. PARTICIPANTS: Adult, English- and Spanish-speaking patients presenting for acute care of non-emergent medical problems. MEASUREMENTS AND MAIN RESULTS: Satisfaction with overall clinic visit and with 7 provider characteristics was evaluated by multiple logistic regression, controlling for age, gender, ethnicity, education, insurance status, having a routine source of medical care, and baseline health. “Language-concordant” patients, defined as Spanish-speaking patients seen by Spanish-speaking providers and English-speaking patients, and patients using AT&T telephone interpreters reported identical overall visit satisfaction (77%; P = .57), while those using family or ad hoc interpreters were significantly less satisfied (54% and 49%; P < .01 and P = .007, respectively). AT&T interpreter use and language concordance also yielded similar satisfaction rates for provider characteristics (P > .2 for all values). Compared to language-concordant patients, patients who had family members interpret were less satisfied with provider listening (62% vs 85%; P = .003), discussion of sensitive issues (60% vs 76%; P = .02), and manner (62% vs 89%; P = .005). Patients who used ad hoc interpreters were less satisfied with provider skills (60% vs 83%; P = .02), manner (71% vs 89%; P = .02), listening (54% vs 85%; P = .002), explanations (57% vs 84%; P = .02), answers (57% vs 84%; P = .05), and support (63% vs 84%; P = .02). CONCLUSIONS: Spanish-speaking patients using AT&T telephone interpretation are as satisfied with care as those seeing language-concordant providers, while patients using family or ad hoc interpreters are less satisfied. Clinics serving a large population of Spanish-speaking patients can enhance patient satisfaction by avoiding the use of untrained interpreters, such as family or ad hoc interpreters

A conceptual framework for Hispanic oral health care

The need to study the health and health care determinants of US Hispanics is mandated by their rapid population growth. Nonetheless, it is challenging to study such a diverse population that incorporates many similarities and differences in values and experiences. This paper aims to highlight the factors that should be considered in Hispanic oral health research in the United States, and presents, in a theoretical framework, the relationships between these factors. The proposed ecological framework is supported by an extensive literature review, with an emphasis on the factors that are reported to differ among ethnic groups. It has a foundation in social science and is based on existing models from different fields of knowledge. To be comprehensive, the framework simultaneously addresses individual and environmental constructs. Within these, antecedent factors shape the intention to seek oral health care, while empowerment factors play a mediating role between intention and actual receipt of care. Individual antecedent factors incorporate risk markers, need, and predisposing factors. Environmental antecedent factors are represented by social constructs that allude to the population's health culture. Empowerment factors explain the level of control that a person perceives or the environment provides in receiving care. A thorough consideration of the factors that drive Hispanics' oral health care usage will aid US researchers and practitioners in improving this population's health and access to care.Gloria C.
