Albuminuria and Risk of Cardiovascular Events and Mortality in a General Population of Patients with Type 2 Diabetes Without Cardiovascular Disease: A Danish Cohort Study.

BACKGROUND: Albuminuria level is associated with cardiovascular events and mortality in patients with diabetes. However, little is known about the association between albuminuria level in diabetes patients without overt cardiovascular disease. We aimed to examine the association between albuminuria level and the risk of ischemic stroke, myocardial infarction, and all-cause mortality in patients with type 2 diabetes without overt cardiovascular disease. METHODS: We linked Danish nationwide registries to identify patients with type 2 diabetes without cardiovascular disease from May 2005 through June 2015. Patients were followed for the outcomes ischemic stroke, myocardial infarction, and all-cause mortality until December 31, 2015. Albuminuria level was based on 2 consecutive measurements of the urinary albumin excretion rate or albumin-to-creatinine ratio. Associations between albuminuria level and incidence of cardiovascular disease and mortality were evaluated with Cox proportional hazard regression. RESULTS: The study population consisted of 69,532 patients with type 2 diabetes without cardiovascular disease. When comparing patients with microalbuminuria to patients with normoalbuminuria, in an analysis adjusted for cardiovascular risk factors, we found hazard ratios of 1.28 (95% confidence interval [CI], 1.07-1.52), 1.34 (95% CI, 1.10-1.62), and 1.48 (95% CI, 1.36-1.61) for ischemic stroke, myocardial infarction, and all-cause mortality, respectively. For macroalbuminuria, the hazard ratios were 1.81 (95% CI, 1.46-2.23), 1.99 (95% CI, 1.59-2.48), and 1.83 (95% CI, 1.64-2.04). Similar results were found after adjusting for concomitant medication. CONCLUSIONS: This study showed that albuminuria level is associated with higher risk of incident ischemic stroke, myocardial infarction, and all-cause mortality in Type 2 diabetes patients without overt cardiovascular disease.

Glycemic Status and Thromboembolic Risk in Patients With Atrial Fibrillation and Type 2 Diabetes Mellitus: A Danish Cohort Study.

Background Diabetes mellitus is associated with increased risk of stroke in patients with atrial fibrillation, and differences in glycemic status may affect this risk. We aimed to examine the effect of glycemic status evaluated by hemoglobin A1c (HbA1c) on the risk of thromboembolism among patients with atrial fibrillation and type 2 diabetes mellitus. Methods In this cohort study, we used data from Danish registries to identify patients with type 2 diabetes mellitus and incident nonvalvular atrial fibrillation in the period of May 1, 2005, through December 31, 2015. On the basis of the most recent HbA1c measurement before an incident atrial fibrillation diagnosis, patients were divided into the categories: HbA1c ≤48 mmol/mol, HbA1c=49-58 mmol/mol, and HbA1c >58 mmol/mol. Cox regression analysis was used to estimate hazard ratios for the outcome thromboembolism. Results The study population included 5386 patients with incident nonvalvular atrial fibrillation and type 2 diabetes mellitus. Compared with patients with HbA1c ≤48 mmol/mol, we observed a higher risk of thromboembolism among patients with HbA1c=49-58 mmol/mol (hazard ratio, 1.49; 95% CI, 1.09-2.05) and HbA1c >58 mmol/mol (hazard ratio, 1.59; 95% CI, 1.13-2.22) after adjusting for confounding factors. When stratified on diabetes mellitus duration, similar results were found among patients with diabetes mellitus duration of <10 years. Contrastingly, in patients with diabetes mellitus duration of ≥10 years, higher HbA1c levels were not associated with a higher risk of thromboembolism. Conclusions In patients with incident atrial fibrillation and type 2 diabetes mellitus, increasing levels of HbA1c were associated with a higher risk of thromboembolism. However, no association was found among patients with diabetes mellitus duration ≥10 years.

Cost-effectiveness of treatments for non-osteoarthritic knee pain conditions: A systematic review.

INTRODUCTION: Knee pain is common in adolescents and adults and is associated with an increased risk of developing knee osteoarthritis. The aim of this systematic review was to gather and appraise the cost-effectiveness of treatment approaches for non-osteoarthritic knee pain conditions. METHOD: A systematic review was conducted according to the PRISMA guidelines and registered on PROSPERO (CRD42016050683). The literature search was done in MEDLINE via PubMed, EMBASE, The Cochrane Library, and the National Health Service Economic Evaluation Database. Study selection was carried out by two independent reviewers and data were extracted using a customized extraction form. Study quality was assessed using the Consensus on Health Economic Criteria list. RESULTS: Fifteen studies were included. The majority regarded the treatment of anterior cruciate ligament (ACL) injuries, but we also identified studies evaluating other knee pain conditions such as meniscus injuries, cartilage defects, and patellofemoral pain syndrome. Study interventions were categorized as surgical or non-surgical interventions. The surgical interventions included ACL reconstruction, chondrocyte implantation, meniscus scaffold procedure, meniscal allograft transplantation, partial meniscectomy, microfracture, and different types of autografts and allografts. The non-surgical management consisted of physical therapy, rehabilitation, exercise, counselling, bracing, and advice. In general, for ACL injuries surgical management alone or in combination with rehabilitation appeared to be cost-effective. The quality of the economic evaluations was of moderate to high quality. CONCLUSION: There was insufficient evidence to give a firm overview of cost-effective interventions for non-osteoarthritic knee pain, but surgical treatment of acute ACL injury appeared cost-effective. There is very little data regarding the cost-effectiveness of non-surgical interventions for non-traumatic knee conditions.
