The objectives were to conduct a meta-analysis in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards to determine effect sizes (Cohen’s d) for cognitive dysfunction in adults with type 2 diabetes, relative to nondiabetic controls, and to obtain effect sizes for the most commonly reported neuropsychological tests within domains. Twenty-four studies, totaling 26,137 patients (n = 3351 with diabetes), met study inclusion criteria. Small to moderate effect sizes were obtained for five of six domains: motor function (3 studies, n = 2374; d = −0.36), executive function (12 studies, n = 1784; d = −0.33), processing speed (16 studies, n = 3076; d = −0.33), verbal memory (15 studies, n = 4,608; d = −0.28), and visual memory (6 studies, n = 1754; d = −0.26). Effect size was smallest for attention/concentration (14 studies, n = 23,143; d = −0.19). The following tests demonstrated the most notable performance decrements in diabetes samples: Grooved Pegboard (dominant hand) (d = −0.60), Rey Auditory Verbal Learning Test (immediate) (d = −0.40), Trails B (d = −0.39), Rey-Osterreith Complex Figure (delayed) (d = −0.38), Trails A (d = −0.34), and Stroop Part I (d = −0.28). This study provides effect sizes to power future epidemiological and clinical diabetes research studies examining cognitive function and to help inform the selection of neuropsychological tests.

Background Although African American adults bear a disproportionate burden from diabetes mellitus (DM), few randomized controlled trials have tested culturally appropriate interventions to improve DM care. Methods We randomly assigned 542 African Americans with type 2 DM enrolled in an urban managed care organization to either an intensive or minimal intervention group. The intensive intervention group consisted of all components of the minimal intervention plus individualized, culturally tailored care provided by a nurse case manager (NCM) and a community health worker (CHW), using evidence-based clinical algorithms with feedback to primary care providers (eg, physicians, nurse practitioners, or physician assistants). The minimal intervention consisted of mailings and telephone calls every 6 months to remind participants about preventive screenings. Data on diabetic control were collected at baseline and at 24 months by blind observers; data emergency department (ER) visits and hospitalizations were assessed using administrative data. Results At baseline, participants had a mean age of 58 years, 73% were women, and 50% were living in poverty. At 24 months, compared with the minimal intervention group, those in the intensive intervention group were 23% less likely to have ER visits (rate difference [RD], −14.5; adjusted rate ratio [RR], 0.77; 95% confidence interval [CI], 0.59-1.00). In on-treatment analyses, the rate reduction was strongest for patients who received the most NCM and CHW visits (RD, −31.0; adjusted RR, 0.66; 95% CI, 0.43–1.00; rate reduction ↓ 34%). Conclusion These data suggest that a culturally tailored intervention conducted by an NCM/CHW team reduced ER visits in urban African Americans with type 2 DM.

Background Many patients with chronic kidney disease (CKD) have difficulties becoming actively engaged in the pursuit of pre-emptive living donor kidney transplantation. Study Design The Talking About Live Kidney Donation (TALK) study was a randomized controlled trial of the effectiveness of educational and social worker interventions designed to encourage early discussions and active pursuit of pre-emptive LKT among patients with progressive CKD. Setting & Participants We recruited participants with progressive CKD from academically affiliated nephrology practices in Baltimore, Maryland. Intervention Participants randomly received 1) “Usual Care” (routine care with their nephrologists), 2) “TALK Education” intervention (video and booklet), or the 3) “TALK Social Worker” intervention (video and booklet plus patient and family social worker visits). Outcomes We followed participants for 6 months to assess their self-reported achievement of behaviors reflecting their discussions about LKT and/or pursuit of LKT (discussions with family; discussions with physicians; initiating recipient evaluation; completing recipient evaluation; identifying a potential living donor). Measurements We assessed outcomes via questionnaire at 1, 3, and 6-month follow up. Results Participants receiving Usual Care with their nephrologists (n=44), TALK Education (n=43), and the TALK Social Worker (n=43) were similar at baseline. TALK Study interventions improved participants’ LKT discussion and pursuit behaviors, with the Social Worker leading to greater patient activation (participants’ predicted probability (95% confidence interval) of achieving LKT discussions, evaluations, or donor identification over 6 months in Usual Care, TALK Education, and TALK Social Worker groups: 30% (20%–46%), 42% (33% –54%), and 58% (41% –83%), respectively (p=0.03). Limitations Our population was well educated and mostly insured, potentially limiting generalizability of our findings. Conclusions TALK interventions improved discussion and active pursuit of LKT among patients with progressive CKD and may improve their utilization of pre-emptive LKT.

Management of chronic illnesses is a significant public health concern that is made more challenging by problems of regimen adherence. Effective self-management of chronic illnesses such as diabetes requires not only technical skill to perform regimen behaviors but also problem-solving skills to manage daily barriers to regimen adherence and to make appropriate adjustments to the self-care regimen. A review of the empirical literature on the relation between problem solving and disease self-management in diabetes, a chronic illness exemplar, illuminates methodological limitations that indicate a need for a theoretical framework for problem solving applied to chronic disease self-management. A problem-solving model of chronic disease self-management is proposed, derived from theories of problem solving in cognitive psychology, educational/learning theory, and social problem solving. Four essential components of problem solving in disease self-management are identified: (a). problem-solving skill, (b). problem-solving orientation, (c). disease-specific knowledge, and (d). transfer of past experience. The model is illustrated, and empirical support for this problem-solving model in the diabetes literature is discussed. The model has utility in driving testable hypotheses regarding the relation of disease-specific problem solving to chronic illness management, in developing problem-solving assessment instruments relevant to disease self-management, and in guiding disease self-management training and interventions.

BACKGROUND: Lower socioeconomic status is associated with excess disease burden from diabetes. Diabetes self-management support interventions are needed that are effective in engaging lower income patients, addressing competing life priorities and barriers to selfcare, and facilitating behavior change. OBJECTIVE: To pilot test feasibility, acceptability, and effect on disease control of a problem-based diabetes self-management training adapted for low literacy and accessibility. DESIGN: Two-arm randomized controlled trial powered to detect a 0.50% change in A1C at follow-up with a 2-sided alpha of 0.05 in a pooled analysis. PARTICIPANTS: Fifty-six urban African-American patients with type 2 diabetes and suboptimal blood sugar, blood pressure, or cholesterol control recruited from a diabetes registry within a university-affiliated managed care organization. INTERVENTIONS: A group, problem-based diabetes self-management training designed for delivery in an intensive and a condensed program format. Three intensive and three condensed program groups were conducted during the trial. MAIN MEASURES: Clinical (A1C, systolic blood pressure [SBP], diastolic blood pressure [DBP], LDL and HDL cholesterol) and behavioral (knowledge, problem solving, self-management behavior) data were measured at baseline, post-intervention, and 3 months post-intervention (corresponding with 6-9 months following baseline). RESULTS: Adoption of both programs was high (>85% attendance rates, 95% retention). At 3 months postintervention, the between-group difference in A1C change was −0.72% (p =0.02), in favor of the intensive program. A1C reduction was partially mediated by problem-solving skill at follow-up (ß = −0.13, p=0.04). Intensive program patients demonstrated within-

Objectives: Women with a history of gestational diabetes mellitus (GDM) have an increased risk of developing type 2 diabetes (T2DM) but often do not return for follow-up care. We explored barriers to and facilitators of postpartum follow-up care in women with recent GDM. Methods: We conducted 22 semistructured interviews, 13 in person and 9 by telephone, that were audiotaped and transcribed. Two investigators independently coded transcripts. We identified categories of themes and subthemes. Atlas.ti qualitative software (Berlin, Germany) was used to assist data analysis and management. Results: Mean age was 31.5 years (standard deviation) [SD] 4.5), 63% were nonwhite, mean body mass index (BMI) was 25.9 kg=m 2 (SD 6.2), and 82% attended a postpartum visit. We identified four general themes that illustrated barriers and six that illustrated facilitators to postpartum follow-up care. Feelings of emotional stress due to adjusting to a new baby and the fear of receiving a diabetes diagnosis at the visit were identified as key barriers; child care availability and desire for a checkup were among the key facilitators to care. Conclusions: Women with recent GDM report multiple barriers and facilitators of postpartum follow-up care. Our results will inform the development of interventions to improve care for these women to reduce subsequent diabetes risk.
