This paper reports on mediation analysis of effects of the Adelante brand, an innovative program for Latino immigrant adolescents and their families, and positive youth development (PYD) outcomes. Specific objectives were to increase adolescent engagement and participation in a community-based program called Adelante, based on PYD theory, which sought to reduce substance use, sexual risk taking, and interpersonal violence among Latino immigrant youth. A total of 238 parent-child dyads were recruited from a predominantly low-income Latino immigrant community and followed for an average of 22 months. Measures included demographics; acculturation; stress and coping; social support; violence, substance use, and sexual risk attitudes; future expectations; the Adelante brand equity scale; and PYD asset measures. Multiple regression modeling shows that the leadership brand equity construct is associated with decreased proviolence and increased antiviolence attitudes. Additionally, having any program exposure (vs. none) is associated with improved substance abuse attitudes in models adjusting for the loyalty brand equity construct. In mediation analysis, we observed a mediating effect of the leadership brand equity construct on improved antiviolence attitudes among those exposed to the Adelante program. As found in previous research, Adelante brand equity operated as a mediator of program effects on Latino youth PYD outcomes.  相似文献

IntroductionThere is a lack of scientific studies on the assessment of patients with vestibular disorders associated with sleep quality disorders and its impact on the balance and overall quality of life.Objectivesto assess the impact of the sleep quality on the balance and quality of life of individuals with peripheral vestibulopathies.Methods52 individuals with peripheral vestibulopathies underwent sleep quality assessment through the Pittsburgh sleep quality index, neurotological examination through dizziness handicap inventory and Tetrax posturography (Sunlight Medical Ltd.) in eight sensory conditions. Thirty-two healthy individuals (G3) participated as the control group.ResultsFourteen individuals with vestibulopathy had good quality of sleep (G1) and 38 showed poor quality of sleep (G2) as demonstrated by the Pittsburgh sleep quality index global scores (p = 0.001). The dizziness handicap inventory showed worse impact of the dizziness on the quality of life in G2 when compared to G1 (p  = 0.045). The G2 showed higher risk of falling in posturography when compared to G3 (p = 0.012) and higher index of postural instability in five sensory conditions in comparison with G3. In the vestibulopathy groups, the worse the sleep quality, the higher the risk of falling (r = 0.352) and the worse the quality of life (r = 0.327).ConclusionIndividuals with peripheral vestibulopathies and poor quality of sleep demonstrate worse balance evidenced by increased postural instability, higher risk of falls and worse perceived quality of life. The quality of sleep is a predictive factor for worse perceived quality of life and for higher risk of falls in individuals with peripheral vestibulopathies.  相似文献

The Brazilian Public Health Service provides freely αPEG-IFN to treat patients infected with HCV. The primary goal of HCV therapy is the long-term elimination of HCV from the blood to reduce the risk of HCV associated complications and death. Patient viremia affects the treatment duration and response, thus influencing clinical decisions. We developed a high-throughput method to perform the quantification of RNA hepatitis C virus (HCV) virus load in plasma samples to monitor patients under treatment. The method is based on a duplex detection, in a one-step real-time RT-PCR assay and it has been validated according to the rules established by the official Brazilian regulatory agency (ANVISA). This new method was compared to a commercial kit (Cobas/Taqman HCV Test v2.0 - Roche), showing virus load results with significant correlation between them (p?=?0,012) using commercial and clinical panels. In addition, 611 samples from patients treated with peguilated alfa-interferon (αPEG-IFN) from different regions of Brazil were analyzed. Our one-step real-time RT-PCR assay demonstrated good performance in viral load measurement and in treatment course monitoring, with acceptable sensitivity and specificity values  相似文献

With the objective to evaluate the behavior of paracoccidioidomycosis in the last three decades, clinical and epidemiological data of 595 patients admitted to clinical services of the Federal University of Mato Grosso do Sul from 1980 to 2009 were investigated. Gender, age distribution, clinical form, comorbidity with tuberculosis or AIDS, and mortality were compared by decades of clinical admission. It was shown that during the three decades there was a decrease in women percentage, and the same manner occurred a reduction in participants in the age group of 20 to 39 years. Moreover, the acute/subacute forms have been diminished in the period. These fluctuations are closely related and can be simultaneously analyzed. Increased AIDS co-infection prevalence from the first to the second decade was also revealed, coinciding with the appearance of the retroviral epidemic and stabilizing during the third decade. No change in the tuberculosis co-infection rate was observed (overall = 6.9%). It reinforces the importance of this co-morbidity. The overall mortality rate remained steady at 6.7%, not varying significantly from one decade to another. The persistent mortality rate calls attention to the importance of this neglected disease.  相似文献

Atrial fibrillation (AF) is a progressive chronic disease characterized by exacerbations and periods of remission. It is estimated that up to 20% to 30% of those with AF also have coronary artery disease (CAD), and 5% to 15% will require percutaneous coronary intervention (PCI). In patients with concomitant AF and CAD, management remains challenging and requires a careful and balanced assessment of the risk of bleeding against the anticipated impact on ischemic outcomes (AF-related stroke and systemic embolism, as well as ischemic coronary events). Oral anticoagulation (OAC) is indicated for the prevention of AF-related stroke and systemic embolism, whereas antiplatelet therapy is indicated for the prevention of coronary events. Each offers a relative efficacy benefit (dual antiplatelet therapy [DAPT] is more effective than OAC alone in reducing cardiovascular death, myocardial infarction, stent thrombosis, and ischemic coronary events in a population with acute coronary syndromes [ACS]), but with a relative compromise (DAPT is significantly inferior to OAC for the prevention of stroke/systemic embolism in an AF population at increased risk of stroke). The purpose of this review is to explore the current evidence and rationale for antithrombotic treatment strategies in patients with both AF and CAD. Specifically, there is a focus on how to best tailor the therapeutic choices (OAC and antiplatelet therapy) to individual patients based on their underlying coronary presentation.  相似文献
