Simultaneous interval estimates of the odds ratio in studies with two or more comparisons

More than one odds ratio estimate will often arise from a single epidemiologic study. Examples of designs where this may occur include those where there is more than one case or control group, and investigations of several risk factors as part of the same study. Various methods for presenting multiple interval estimates are discussed, including: the naive method, the Bonferroni method, the Dunn method, the Scheffé method, and the Dunnett method. For rectangular regions the Dunnett method gives a region with the most appropriate confidence level, but this region contains a different set of odds ratio estimates than are implied by the usual significance tests. A confidence ellipse circumscribed by the Scheffé limits gives the best agreement with the significance tests. Each of these methods is illustrated with a numerical example.     

Defining Community Readiness for the Implementation of a System of Care

Developing systems of care for children with emotional disorders requires changes in the organization and delivery of services. Using concept mapping, the authors conducted a study to define factors of a community’s readiness to make such changes. Participants were from 25 of 27 federally-funded, advanced sites, plus a panel of experts. The participants completed three tasks: brainstorming, rating, and sorting. This process produced eight factors: Leadership, Network of Local Partners, Shared Goals, Collaboration, Families and Youth as Partners, Accountability, Evaluation, and Plans to Expand Services. Understanding factors that contribute to successful implementation should help communities identify and make needed changes.

Administrative Issues in Child Psychiatry

Administrative issues related to operating child and adolescent psychiatry programs or child mental health centers are substantially different than their adult counterpart programs. The increasing demands from managed care and other regulatory agencies make these programs difficult to operate. The smaller scale of these programs and the fewer existing programs make managing access to care more complicated. The administrators and clinicians in these programs have to be vigilant of legal responsibilities and reporting mandates that child practitioners and agencies that treat children need to abide by. In order to continue thriving, programs need to be efficient and fiscally viable. Issues such as building the continuum of care and finding the qualified personnel to staff these services are discussed in this article.     

Midlife C-reactive protein and risk of cognitive decline: a 31-year follow-up

There is evidence for a relationship between raised inflammatory markers, including high sensitivity C-reactive protein (hs-CRP), measured late in life, and an increased risk of cognitive decline and dementia. This study evaluates the association of midlife hs-CRP concentrations with late-life longitudinal trends in cognitive function. Data are from the Honolulu-Asia Aging Study (HAAS), a longitudinal community-based study of Japanese American men. hs-CRP levels were measured on average 25 years before cognitive testing began in 1991. Subjects were followed from up to three follow-up examinations (mean of 6.1 years). At each exam, cognitive function was measured with the Cognitive Abilities Screening Instrument (CASI). This analysis includes a sub-sample of 691 subjects dementia-free in 1991. With incident dementia cases included, those with the highest quartile of hs-CRP had significantly more cognitive decline than those in the lowest quartile, after adjustment for baseline CASI score, demographic and cardiovascular risk factors. When cases were removed, there was no difference in cognitive decline by CRP quartile. This relationship was not modified by the presence of apolipoprotein E varepsilon4. These findings suggest that inflammatory mechanisms during midlife may reflect underlying processes contributing to dementia-related cognitive decline late in life.
