BACKGROUND Comorbidity is an important adjustment measure in research focusing on outcomes such as health status and mortality. One recurrent methodological issue concerns the concordance of comorbidity data obtained from different reporting sources. The purpose of these prospectively planned analyses was to examine the concordance of comorbidity data(More)
Fractional differential equations are an important and useful tool in many areas of science and engineering [1, 2, 3, 4, 5]. In a heterogeneous environment, the coefficients of the diffusion equation will naturally vary in space. Pearson diffusions form a tractable class of variable coefficient diffusion models with polynomial coefficients. The process X 1(More)
More than 80% of women with breast cancer are now reported to be using complementary and alternative medicine (CAM) therapies during conventional treatment. A randomized clinical trial (RCT) of reflexology with late stage breast cancer patients serves as the data source for this article. The purposes were to investigate: (i) reasons for refusal to(More)
The purpose of this secondary data analysis, guided by allostatic load theory, was to compare depressive symptoms and their correlates in men and women following mild or moderate traumatic brain injury (n = 159). Using general linear modeling procedures in the Statistical Analysis Software, women reported significantly higher Center for Epidemiological(More)
The purpose of this study was to psychometrically test the Adolescent Physical Activity Perceived Benefits and Barriers Scales developed for middle-school-age youth. A total of 206 racially diverse 6th, 7th, and 8th graders completed questionnaires at two time points (2 weeks apart). For the 10-item Perceived Benefits Scale and the 9-item Perceived Barriers(More)

Children affected by HIV are at increased risk of developmental and neuropsychological disturbances due to direct effects of HIV on the brain and direct effects associated with living in poverty. Caregivers can play an important role, through quality caregiving, in mitigating the negative effect of these stressors. This study used baseline data from an(More)
Asymptomatic falciparum malaria is associated with poorer cognitive performance in African schoolchildren and intermittent preventive treatment of malaria improves cognitive outcomes. However, the developmental benefits of chemoprevention in early childhood are unknown. Early child development was evaluated as a major outcome in an open-label, randomized,(More)
BACKGROUND CogState is a widely used computer-based cognitive test whose validity has not been addressed in resource poor settings. We examined the construct, concurrent and convergent validity of CogState, test-retest reliability and the effect of sociodemographic variables on CogState outcomes in school age children. METHODS Two hundred and thirty(More)
Cancer is on the rise, and the effectiveness of oral anticancer agent (OA) treatment depends heavily on adherence to the prescribed regimen. Adherence, however, is a significant problem with 42% of patients missing OA doses due to poor memory recall, lack of knowledge, incompatible beliefs, and depressive symptoms. Short Message Service (SMS) messaging may(More)
Due to the extensive applications of fractional differential equations (FDEs) in engineering and science, research in this area has grown significantly. Fractional Dynamic Systems are described by FDEs, and this special issue consists of 8 original articles covering various aspects of FDEs and their applications written by prominent researchers in the(More)
