A randomized trial of a primary care-based disease management program to improve cardiovascular risk factors and glycated hemoglobin levels in patients with diabetes

PURPOSE: To assess the efficacy of a pharmacist-led, primary care-based, disease management program to improve cardiovascular risk factors and glycated hemoglobin (A(1C)) levels in vulnerable patients with poorly controlled diabetes. METHODS: A randomized controlled trial of 217 patients with type 2 diabetes and poor glycemic control (A(1C) level >or=8.0%) was conducted at an academic general medicine practice from February 2001 to April 2003. Intervention patients received intensive management from clinical pharmacists, as well as from a diabetes care coordinator who provided diabetes education, applied algorithms for managing glucose control and decreasing cardiovascular risk factors, and addressed barriers to care. Control patients received a one-time management session from a pharmacist followed by usual care from their primary care provider. Outcomes were recorded at baseline and at 6 and 12 months. Primary outcomes included blood pressure, A(1C) level, cholesterol level, and aspirin use. Secondary outcomes included diabetes knowledge, satisfaction, use of clinical services, and adverse events. RESULTS: For the 194 patients (89%) with 12-month data, the intervention group had significantly greater improvement than did the control group for systolic blood pressure (-9 mm Hg; 95% confidence interval [CI]: -16 to -3 mm Hg) and A(1C) level (-0.8%; 95% CI: -1.7% to 0%). Change in total cholesterol level was not significant. At 12 months, aspirin use was 91% in the intervention group versus 58% among controls (P <0.0001). Intervention patients had greater improvements in diabetes knowledge and satisfaction than did control patients. There were no significant differences in use of clinical services or adverse events. CONCLUSION: Our comprehensive disease management program reduced cardiovascular risk factors and A(1C) levels among vulnerable patients with type 2 diabetes and poor glycemic control.     

Application of geographic information systems and remote sensing to schistosomiasis control in China

Progress in China on developing prediction models using remote sensing, geographic information systems and climate data with historical infection prevalence and malacology databases is reviewed. Special reference is made to the effects of the Yangtze river Three Gorges dam project on environmental changes that may impact changes in the spatial and temporal distribution and abundance of Schistosoma japonicum in China, and the future success of disease control programs.     

Corticosteroids for Pneumocystis carinii pneumonia with acute respiratory failure. Experience with rescue therapy.

Corticosteroids have proven effective as adjunctive therapy for the treatment of PCP in patients with AIDS, when begun within 72 h of conventional anti-Pneumocystis therapy. Their efficacy as rescue (or salvage) therapy in patients who have failed conventional therapy, however, remains unproven. Ths report presents our experience with 16 patients admitted to our MICU for acute respiratory failure (PaO2/FIO2 ratio less than or equal to 150) due to PCP. Five of six patients (83 percent) who received "primary" CS rescue (initial CS use prompted by acute respiratory failure after 72 h of conventional anti-Pneumocystis therapy) survived hospitalization. Our experience suggests that CSs may be effective even when started after 72 h of conventional therapy. Additional studies are needed to clarify the role of CS rescue therapy.     

p16INK4A and p15INK4B gene deletions in primary leukemias

The 9p21 locus has been deleted at a high frequency in a wide variety of tumors. Recently, two genes, p16INK4A and p15INK4B (also called MTS1 and MTS2), have been localized in close proximity at the 9p21 locus, encoding cyclin-dependent kinases 4/6 inhibitors of relative molecular mass 16 kD and 15 kD, respectively and also found to be deleted at a high frequency in tumor cell lines. We analyzed p16INK4A and p15INK4B genes in 178 cases of primary leukemias including 81 cases of chronic lymphocytic leukemia (CLL), seven of hairy cell leukemia (HCL), seven of chronic myelogenous leukemia (CML), 43 of acute myelogenous leukemia (AML), 27 of acute lymphoblastic leukemia (ALL), and 13 of myelodysplastic syndrome (MDS) by Southern blot analyses. The ALL cases showed a relatively high frequency of homozygous deletions (22%, 6 of 27) at the p16INK4A gene locus. Interestingly, of the six cases with p16INK4A homozygous deletions, only three showed homozygous deletions at the p15INK4B gene. In 81 CLL patients, we detected one homozygous and five heterozygous deletions at both the p16INK4A and p15INK4B genes and two heterozygous deletions at the p16INK4A gene alone. Deletion of these two genes in AML cases is relatively low (9%). We did not detect deletions in any of the MDS, HCL, and CML cases examined. Sequence analyses of p16INK4A gene of six CLL cases with heterozygous deletion at this locus showed a 27-bp deletion at the splice acceptor site of intron 1 in one case and changes in the coding sequence in three other cases. The data presented in this report showed that (1) p16INK4A and p15INK4B genes are preferentially deleted homozygously in ALL and heterozygously in CLL cases with frequent mutation in the second allele, and (2) p16INK4A gene appears to be more frequently deleted than p15INK4B gene.     

White matter tract signatures of the progressive aphasias

The primary progressive aphasias (PPA) are a heterogeneous group of language-led neurodegenerative diseases resulting from large-scale brain network degeneration. White matter (WM) pathways bind networks together, and might therefore hold information about PPA pathogenesis. Here we used diffusion tensor imaging and tract-based spatial statistics to compare WM tract changes between PPA syndromes and with respect to Alzheimer's disease and healthy controls in 33 patients with PPA (13 nonfluent/agrammatic PPA); 10 logopenic variant PPA; and 10 semantic variant PPA. Nonfluent/agrammatic PPA was associated with predominantly left-sided and anterior tract alterations including uncinate fasciculus (UF) and subcortical projections; semantic variant PPA with bilateral alterations in inferior longitudinal fasciculus and UF; and logopenic variant PPA with bilateral but predominantly left-sided alterations in inferior longitudinal fasciculus, UF, superior longitudinal fasciculus, and subcortical projections. Tract alterations were more extensive than gray matter alterations, and the extent of alteration across tracts and PPA syndromes varied between diffusivity metrics. These WM signatures of PPA syndromes illustrate the selective vulnerability of brain language networks in these diseases and might have some pathologic specificity.     

Assessing Adolescent Personality Disorders With the Shedler–Westen Assessment Procedure for Adolescents

This two‐part study describes the development and validation of a method for quantifying adolescent personality pathology using the latest edition of the Shedler–Westen Assessment Procedure for Adolescents (SWAP‐II‐A), an instrument designed to be used by clinically experienced observers. In Study 1, experienced psychologists and psychiatrists described a normative clinical sample of 950 North American patients. Study 2 applied the SWAP‐II‐A in a day treatment setting. Results indicated that SWAP‐II‐A personality disorder (PD) scales evidenced high internal consistency, construct validity with Diagnostic and Statistical Manual of Mental Disorders (5th ed.) symptoms and diagnoses, and concurrent validity with Child Behavior Checklist (CBCL) ratings. Independent observers saw patients similarly, and PD assessments were significantly associated with CBCL scale scores and ward behavior.
