Perceived adherence to prescribed treatment in juvenile idiopathic arthritis over a one‐year period

Objective

To document perceived adherence to treatment (taking medications and performing exercises) in patients with juvenile idiopathic arthritis (JIA) over a 1‐year period and to identify related factors.

Methods

We surveyed parents of patients with JIA at the Montreal Children's Hospital and British Columbia's Children's Hospital in Vancouver. Parents were asked to respond to a series of questionnaires every 3 months over a 12‐month period. Perceived adherence was evaluated on a 100‐mm visual analog scale (VAS) in the Parent Adherence Report Questionnaire (PARQ). Parental coping, distress, child function, disease severity and duration, perceived helpfulness of treatment, problems encountered, and sociodemographic data were also assessed.

Results

The mean age of our sample of 175 children was 10.2 years; mean age at diagnosis was 6.1 years and mean disease duration was 4.1 years. Perceived adherence to medications was consistently high, with average adherence at baseline, 3, 6, 9, and 12 months being 86.1, 91.7, 90.4, 92.0, and 88.8, respectively, on the PARQ VAS. Perceived adherence to exercise was lower but remained steady, with corresponding means of 54.5, 64.1, 61.2, 63.0, and 54.3, respectively. Using generalized estimating equation analysis, factors associated with higher perceived adherence to medications included perceived helpfulness of medications and lower disease severity; those associated with higher perceived adherence to exercise were younger age of the child, child involvement in responsibility for treatment, and higher perceived helpfulness of the treatment.

Conclusion

Belief in helpfulness of treatment is associated with higher parental perceived adherence to treatment.     

A genomic analysis of chicken cytokines and chemokines.

As most mechanisms of adaptive immunity evolved during the divergence of vertebrates, the immune systems of extant vertebrates represent different successful variations on the themes initiated in their earliest common ancestors. The genes involved in elaborating these mechanisms have been subject to exceptional selective pressures in an arms race with highly adaptable pathogens, resulting in highly divergent sequences of orthologous genes and the gain and loss of members of gene families as different species find different solutions to the challenge of infection. Consequently, it has been difficult to transfer to the chicken detailed knowledge of the molecular mechanisms of the mammalian immune system and, thus, to enhance the already significant contribution of chickens toward understanding the evolution of immunity. The availability of the chicken genome sequence provides the opportunity to resolve outstanding questions concerning which molecular components of the immune system are shared between mammals and birds and which represent their unique evolutionary solutions. We have integrated genome data with existing knowledge to make a new comparative census of members of cytokine and chemokine gene families, distinguishing the core set of molecules likely to be common to all higher vertebrates from those particular to these 300 million-year-old lineages. Some differences can be explained by the different architectures of the mammalian and avian immune systems. Chickens lack lymph nodes and also the genes for the lymphotoxins and lymphotoxin receptors. The lack of functional eosinophils correlates with the absence of the eotaxin genes and our previously reported observation that interleukin- 5 (IL-5) is a pseudogene. To summarize, in the chicken genome, we can identify the genes for 23 ILs, 8 type I interferons (IFNs), IFN-gamma, 1 colony-stimulating factor (GM-CSF), 2 of the 3 known transforming growth factors (TGFs), 24 chemokines (1 XCL, 14 CCL, 8 CXCL, and 1 CX3CL), and 10 tumor necrosis factor superfamily (TNFSF) members. Receptor genes present in the genome suggest the likely presence of 2 other ILs, 1 other CSF, and 2 other TNFSF members.

Local cerebral blood flow following transient cerebral ischemia. II. Effect of arterial PCO2 on reperfusion following global ischemia

Following 5 minutes of global ischemia, local cerebral blood flow (LCBF) was shown to have an initial reactive hyperemia that was followed, within the first hour, by persistent hypoperfusion (Part I). Intracranial pressure (ICP) was never elevated during the period of poor reperfusion. These experiments attempted to reverse the state of subnormal LCBF by inducing hypercarbia or hyocarbia or maintaining normocarbia. Although hypocarbia did increase LCBF at several electrode sites, neither the intracerebral steal syndrome nor the "squeeze" syndrome are a dominant consequence of hypercarbia in this model of global ischemia. Hypercarbia was consistently more effective in elevating LCBFs and in recovery of the electrocorticogram. It appears that, in the absence of raised ICP, hypercarbia may be preferred to normal or low PACO2,. Even though hypercarbia was superior to normocarbia or hypocarbia, hypercarbia was not a completely satisfactory regimen for reversing the state of poor reperfusion.     

Hispanic health status in Orange County, Florida.

PURPOSE: To assess the health status of the Hispanic population of Orange County, Florida. METHODS: The methodology utilized secondary data for 66 ethnically identified indicators in a comparative framework applied for a 5-year period (1997-2001). FINDINGS: Orange County Hispanics are younger with lower per capita income than their Florida peers, less likely to be White, and much more likely to be of Puerto Rican origin. Relative to the Hispanic populations in the selected peer counties and statewide, Orange County Hispanics have higher age-adjusted death rates for a majority of disease categories and conditions, such as breast, lung, and prostate cancers; chronic liver disease and cirrhosis; diabetes mellitus; pneumonia and influenza; stroke; acquired immunodeficiency syndrome; motor vehicle accidents; and infant, neonatal, and child mortality. Orange County Hispanics did better in comparison to Orange non-Hispanics, with lower age-adjusted death rates for major causes of death such as heart disease, cancer, and stroke. However, for many indicators, the 5-year trends for Orange County Hispanics are moving in an unfavorable direction in contrast to the trends for non-Hispanics, which are either stable or improving. CONCLUSION: Comparative assessments of Hispanic populations using secondary data enable the development of a comprehensive health status profile. However, this approach is currently constrained by the limited number of ethnically identified indicators and, especially for Hispanics, problems in the accuracy and consistency of the assignment to racial categories and subsequent reporting.     

The Activity Support Scale for Multiple Groups (ACTS-MG): Child-reported Physical Activity Parenting in African American and Non-Hispanic White Families

This study aimed to assess the psychometric properties of a child-report, multidimensional measure of physical activity (PA) parenting, the Activity Support Scale for Multiple Groups (ACTS-MG), in African American and non-Hispanic white families. The ACTS-MG was administered to children aged 5 to 12 years. A three factor model of PA parenting (Modeling of PA, Logistic Support, and Restricting Access to Screen-based Activities) was tested separately for mother's and fathers' PA parenting. The proposed three-factor structure was supported in both racial groups for mothers’ PA parenting and in the African American sample for fathers’ PA parenting. Factorial invariance between racial groups was demonstrated for mother's PA parenting. Building on a previous study examining the ACTS-MG parent-report, this study supports the use of the ACTS-MG child-report for mothers’ PA parenting. However, further research is required to investigate the measurement of fathers’ PA parenting across racial groups.     

Core Dimensions of Recovery: A Psychometric Analysis

Core recovery dimensions lie between the large general factor of recovery and its underlying components. Identifying these could enhance recovery frameworks, practice and research. In contrast to existing conceptually based taxonomies, we sought to empirically identify the core dimensions of recovery through further psychometric analysis of a robust eleven factor (sub-scale) consumer recovery outcome measure, My Voice, My Life. We subjected the sub-scale scores of 504 consumers to further principal components analyses, beginning with a single unrotated factor and progressing through two to nine factors with varimax rotation. We found the five-factor solution to provide an orderly intermediate configuration with the eleven recovery factors having either aligned and/or disengaged through the process to result in the following core dimensions: (1) Belonging and relating (encompassing the individual factors of spirituality, culture, and relationships); (2) Being and doing (encompassing the individual factors of physical health, day-to-day life, and quality of life); (3) Thinking and feeling (encompassing the individual factors of recovery, mental health, and hope and empowerment); (4) Resources (which maintained its independence); and (5) Satisfaction with Services (which also maintained its independence). We compare this empirical configuration with conceptually based taxonomies.
