OBJECTIVES:
To evaluate vascular protection treatment patterns and attainment of the 2003 Canadian Diabetes Association’s recommended targets in ambulatory patients with type 2 diabetes.METHODS:
Between 2005 and 2006, 3002 outpatients with type 2 diabetes were enrolled by 229 primary health care settings across Canada. Baseline characteristics, therapeutic regimens and treatment success – defined as the achievement of a blood pressure (BP) of 130/80 mmHg or lower, glycosylated hemoglobin (A1C) of 7% or lower, low-density lipoprotein cholesterol (LDL-C) lower than 2.5 mmol/L and total cholesterol/high-density lipoprotein cholesterol ratio lower than 4.0 – are reported.RESULTS:
Overall, 46% of individuals had a BP that was above the Canadian Diabetes Association’s recommended target. Of these, 11% were untreated, 28% were receiving monotherapy, 38% were not receiving an angiotensin-converting enzyme inhibitor and 16% were not receiving either an angiotensin-converting enzyme inhibitor or an angiotensin receptor blocker. Optimal A1C levels were achieved in 53% of patients. Of those who did not attain A1C targets, 3% were not on glucose-lowering pharmacotherapy and 27% were receiving monotherapy. A total of 74% of patients were treated with statins. Overall, 64% and 62%, respectively, met the target LDL-C and the target total cholesterol/high-density lipoprotein cholesterol ratio. Statins were not prescribed to 43% of patients with LDL-C above target. Antiplatelet therapy was implemented in 81% of patients. In total, 21% achieved the combined targets for BP, A1C and LDL-C.INTERPRETATION:
A substantial proportion of patients did not achieve guideline-recommended targets and were not receiving evidence-based therapy for vascular protection two years after publication of the Canadian guidelines. More research is warranted, and novel and effective strategies must be tested and implemented to correct this ongoing treatment gap. 相似文献12.

In previous studies, we have shown that administration of monoclonal antibody (MoAb) C6B7 against human factor XII to baboons challenged with a lethal dose of Escherichia coli abrogates activation of the contact system and modulates secondary hypotension. To evaluate the contribution of activated contact proteases to the appearance of other inflammatory mediators in this experimental model of sepsis, we studied the effect of administration of MoAb C6B7 on activation of complement and fibrinolytic cascades, stimulation of neutrophil degranulation, and release of the proinflammatory cytokines, tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6). Activation of the complement system, as reflected by circulating C3b/c and C4b/c levels, was significantly reduced in five animals that had received MoAb C6B7 before a lethal dose of E coli as compared with five control animals that had been given a lethal challenge only. Inhibition of contact activation also modulated the fibrinolytic response, since the release of tissue-type plasminogen activator (t-PA) and the appearance of plasmin-alpha2-antiplasmin (PAP) complexes into the circulation was significantly attenuated upon pretreatment with anti-factor XII MoAb. In contrast, plasma levels of plasminogen activator inhibitor (PAI) were modestly enhanced in the treatment group. Degranulation of neutrophils, as assessed by circulating elastase-alpha1-protease inhibitor complexes, and release of IL-6 but not of TNF-alpha was decreased in anti-factor XII-treated animals. Observed differences in the inflammatory response between treatment and control groups were not likely due to different challenges, since the number of E coli that had been infused, as well as circulating levels of endotoxin after the challenge, were similar for both groups. These data suggest that activation of the contact system modulates directly or indirectly various mediator systems involved in the inflammatory response during severe sepsis in nonhuman primates. 相似文献

Since indium-111 white blood cell (In-111 WBC) scintigraphy is often used to evaluate for osteomyelitis in bone fractures, it is important to know if noninfected fractures have In-111 WBC uptake. Twenty-seven noninfected closed fracture sites in 19 patients were prospectively evaluated with technetium-99m methylene diphosphonate bone scintigraphy and In-111 WBC scintigraphy. In-111 WBC uptake was present in 41% of the 27 sites. In the 11 positive sites, the In-111 WBC uptake was 1+ (definite but minimal) in 55%, 2+ (moderate) in 36%, and 3+ (marked) in 9%. The visual intensity of the radioactive uptake on In-111 WBC scintigrams relative to that on bone scintigrams was less in 82%, equal in 9%, and greater in 9%. The visual size of the area of uptake on In-111 WBC scintigrams and bone scintigrams was smaller in 36%, equal in 55%, and greater in 9%. Factors that may help distinction of In-111 WBC uptake due to fracture alone from infection associated with fracture are discussed. 相似文献

Background Although pemphigus is a rare autoimmune blistering disease, it attracts the attention of physicians of many disciplines. Objective This study aims to assess the number of articles on pemphigus that have been published over 15 years in dermatology vs. non‐dermatology medical journals, and to evaluate the quality of available evidence. Methods PubMed was searched for articles on pemphigus published between 1 January 1993 to 31 December 2007 using the search word pemphigus. Articles were characterized by publication type and journal type per year. Regression analysis was used to determine the effect of year of publication on number of publications of each type. Results The search yielded 2032 publications on pemphigus during the evaluation period. Sixty‐one per cent were published in dermatology journals. Overall, the number of publications increased linearly with time. Most of this increase was accounted for by publications in non‐dermatology journals. There was an increase in clinical trials over the course of the study period. The number of certain publications with lower quality of evidence, mainly case reports and letters to the editor, increased significantly in the last few years. There was no increase in publications with high quality of evidence. Conclusions The increase on data from non‐dermatology disciplines is a welcome contribution. Nevertheless, high‐quality evidence on pemphigus is still lacking. We trust that the current trend towards evidence‐based dermatology will impact future research on this severe disease. 相似文献
