A pharmacist and health promoter team to improve medication adherence among Latinos with diabetes.

BACKGROUND: There is a need to improve blood glucose levels of underserved Latino patients with uncontrolled diabetes. OBJECTIVE: To determine the feasibility of a pharmacist and health promoter team designed to address the barriers to medication adherence and adjustment and improve self-care among Latinos with type 2 diabetes. METHODS: Clinical staff at the University of Illinois at Chicago Medical Center referred Latino patients with uncontrolled diabetes (hemoglobin A(1c) [A1C] > or =8.0%) to the study. A research assistant assessed patients on diabetes and medical history, medication list, medication adherence and related habits, health literacy, diabetes knowledge and numeracy, beliefs in benefits of diabetes therapy, depression, social support, and access to care. A bilingual, bicultural health promoter reviewed these assessments and worked with patients through home and clinic visits and telephone calls. The health promoter communicated with a pharmacist to receive assistance in medication management (reconciliation and adjustment). Participants received case management for 6 months. RESULTS: Nine patients were successfully recruited. The mean age was 58 years and mean duration of diabetes was 21 years. Successful collaboration between pharmacists and the health promoter required frequent communication and intense effort to address complex patient barriers. Health promoter contact time, in person, per participant ranged from 0 minutes to 640 minutes, and telephone call time ranged from 27 minutes to 111 minutes during the study period. Eight participants had medication adjustments during the study period, with a maximum of 7 adjustments per participant. Mean hemoglobin A1C declined from an average of 9.6% to 9.0%. Two patients are presented as case studies to describe how the pharmacist-health promoter team functioned. Information was obtained from health promoter records, survey results, and chart reviews. CONCLUSIONS: The pharmacist and health promoter team management of uncontrolled diabetes among Latinos appears to be a feasible approach to improving medication management.

Insulin pump therapy: guidelines for successful outcomes.

PURPOSE: Current forms of insulin delivery used in the treatment of diabetes mellitus (diabetes) include syringes, pens, and insulin pumps. Technical advantages of insulin pump therapy, or continuous subcutaneous insulin delivery (CSII), include precise and flexible insulin dosing. In the context of intensive diabetes management, insulin pumps can facilitate improved long-term glycemic control and reduce the risk for diabetes complications, with improved lifestyle flexibility for patients and their families. Comprehensive patient education, carbohydrate counting, and frequent self-monitoring of blood glucose or continuous glucose monitoring are necessary components of successful insulin pump therapy. Technological advances have increased the appeal of pump therapy to patients and clinicians. Physically, current insulin pumps are discreet, ergonomic, and water resistant. Meanwhile, software improvements have yielded smart pumps with features that support pump users in their daily diabetes management. Robust data analysis software packages allow patients and clinicians unprecedented insight into the quality of diabetes control. Furthermore, widespread insurance reimbursement for CSII has expanded access to therapy. CONCLUSIONS: As the number of pump users and potential users expands, diabetes educators face new challenges and opportunities to improve patients' lives with diabetes. This activity describes the rationale for insulin pump therapy, its potential advantages and disadvantages, and strategies regarding patient selection and education.

Can pre-neoplastic lesions be detected in gastric biopsies of children with Helicobacter pylori infection?

BACKGROUND: Active gastritis, gastric mucosal atrophy and intestinal metaplasia are lesions associated with Helicobacter pylori infection. Atrophy and intestinal metaplasia are only seen in adults. OBJECTIVES: We describe pediatric patients with atrophy and metaplasia, and compare the inflammatory response in these patients to controls. METHODS: As part of a multicenter study of pediatric H. pylori infection, gastric biopsy specimens obtained during diagnostic upper endoscopy of 19 H. pylori-infected children and 45 uninfected controls were reviewed and graded by using the updated Sydney system. The inflammatory response was characterized using immunohistochemistry for T lymphocytes, B lymphocytes, and macrophages, and TUNEL assay for apoptosis. RESULTS: Histology of H. pylori-infected and control biopsy specimens showed active gastritis in 32% and 2% respectively (P = 0.002). Mild intestinal metaplasia was found in 4 H. pylori-infected children, in two of whom it appeared to be accompanied by atrophy. Specimens from patients with H. pylori infection contained increased numbers of B lymphocytes in lymphoid nodules, and apoptosis in the superficial epithelium and inflammatory cells. T lymphocytes and macrophages appeared in similar numbers in specimens from controls and infected patients. CONCLUSIONS: We describe intestinal metaplasia associated with H. pylori infection in children. Since atrophy usually precedes intestinal metaplasia in adults, we suggest that atrophy exists in children. High numbers of B lymphocytes and apoptosis in the surface epithelium are seen in patients with H. pylori infection and may be related to the development of atrophy and intestinal metaplasia.

Early intervention for acute back injury: can we finally develop an evidence-based approach?

OBJECTIVE: Several reviews of the treatment of acute low back pain have been published in the past and have formed the basis of clinical guidelines. However, these lack consistency in some areas and valid data in others. As the literature in this field has continued to expand, the present review was undertaken to establish whether the guidelines in current use are supported by more recently published, scientifically rigorous research, and whether additional consensus regarding treatment of acute low back injury has been forthcoming in recent years. DESIGN: A review, and critical analysis, of literature relating to the treatment of acute low back pain that has been published since the production of the currently used clinical guidelines. The guidelines have been reviewed to assess whether their recommendations remain supportable. CONCLUSIONS: Recent research appears to support current clinical guidelines, i.e. exercise may have a positive effect while bed rest is ineffective and may be harmful, simple analgesics and nonsteroidal anti-inflammatory drugs (NSAIDs) have short-term benefits, and spinal manipulation may be effective in the first four weeks; no evidence was found for traction or back schools. However, we need more randomized controlled trials of treatments shown to be successful with the chronic population, e.g. focused on understanding psychological determinants, and using a multidisciplinary biopsychosocial approach. In the future this may help us to prevent acute low back progressing to the chronic state.
