Engaging Patients and Clinicians in Establishing Research Priorities for Gestational Diabetes Mellitus.

OBJECTIVES: We involved patients and clinicians in Alberta, Canada, to establish research priorities in gestational diabetes mellitus (GDM), using an approach based on a model proposed by the James Lind Alliance (JLA). METHODS: We adapted the 4-step JLA process to engage women with GDM and clinicians to identify uncertainties about the management of GDM. Uncertainties were identified through a survey and a review of the clinical practice guidelines (CPG). Uncertainties were short-listed by a steering committee, followed by a 1-day facilitated workshop using a nominal group format and involving a similar number of patients and clinicians, who identified the top 10 research priorities. RESULTS: Across the various survey formats, 75 individuals submitted 389 uncertainties, the majority (44; 59%) coming from patients. We removed 9 questions as being out of scope or unclear, and 41 were identified on a review of CPG, resulting in a total of 421 uncertainties. After the priority setting process, the final top 10 research priorities included questions about a simpler, more accurate and convenient screening test; risk factors for GDM; improving postpartum diabetes screening; the impact of GDM on the future health of the children; lifestyle challenges and mental health issues; safety, effectiveness and/or impact of diet and/or medication treatments; appropriate timing for delivery; and how care is provided, organized or communicated. CONCLUSIONS: These top 10 research priorities were informed through a comprehensive and transparent process involving women who have experienced GDM as well as clinicians, and they may be regarded as research priorities for GDM.

Interventions to improve influenza and pneumococcal vaccination rates among community-dwelling adults: a systematic review and meta-analysis.

PURPOSE: Influenza and pneumococcal vaccination rates remain below national targets. We systematically reviewed the effectiveness of quality improvement interventions for increasing the rates of influenza and pneumococcal vaccinations among community-dwelling adults. METHODS: We included randomized and nonrandomized studies with a concurrent control group. We estimated pooled odds ratios using random effects models, and used the Downs and Black tool to assess the quality of included studies. RESULTS: Most studies involved elderly primary care patients. Interventions were associated with improvements in the rates of any vaccination (111 comparisons in 77 studies, pooled odds ratio [OR] = 1.61, 95% CI, 1.49-1.75), and influenza (93 comparisons, 65 studies, OR = 1.46, 95% CI, 1.35-1.57) and pneumococcal (58 comparisons, 35 studies, OR = 2.01, 95% CI, 1.72-2.3) vaccinations. Interventions that appeared effective were patient financial incentives (influenza only), audit and feedback (influenza only), clinician reminders, clinician financial incentives (influenza only), team change, patient outreach, delivery site changes (influenza only), clinician education (pneumococcus only), and case management (pneumococcus only). Patient outreach was more effective if personal contact was involved. Team changes were more effective where nurses administered influenza vaccinations independently. Heterogeneity in some pooled odds ratios was high, however, and funnel plots showed signs of potential publication bias. Study quality varied but was not associated with outcomes. CONCLUSIONS: Quality improvement interventions, especially those that assign vaccination responsibilities to nonphysician personnel or that activate patients through personal contact, can modestly improve vaccination rates in community-dwelling adults. To meet national policy targets, more-potent interventions should be developed and evaluated.

MR imaging correlates of white-matter pathology in a preterm baboon model.

INTRODUCTION: Cerebral white-matter (WM) abnormalities on magnetic resonance imaging (MRI) correlate with neurodevelopmental disability in infants born prematurely. RESULTS: Quantitative histological measures of WM and ventricular volumes correlated with qualitative MRI scores of WM volume loss and ventriculomegaly. Diffuse astrocytosis was associated with signal abnormality on T(2)-weighted imaging and higher apparent diffusion coefficient in WM. Loss of oligodendrocytes was associated with lower relative anisotropy characterized by higher radial diffusivity values. The relationship between histopathology and MRI abnormalities was more pronounced in animals in the 28 d model, equivalent to the term human infant. DISCUSSION: MRI reflects microstructural and anatomical abnormalities that are characteristic of WM injury in the preterm brain, and these changes are more evident on MRI at term-equivalent postmenstrual age. METHODS: We assessed the histopathological correlates of MRI abnormalities in a baboon model of premature birth. Baboons were delivered at 125 d of gestation (dg, term ~185 dg) and maintained in an animal intensive care unit for 14 (n = 26) or 28 d (n = 17). Gestational control animals were delivered at 140 dg (n = 9) or 153 dg (n = 4). Cerebral WM in fixed brains was evaluated using MRI, diffusion tensor imaging (DTI), and histopathology.
