Objective. To examine the utility of the Framingham risk score (FRS) in estimating cardiovascular risk in psoriasis.Methods. We compared the predicted 10-year risk of cardiovascular events, namely, cardiovascular death, myocardial infarction, heart failure, percutaneous transluminal coronary angioplasty, and coronary artery bypass grafting using the FRS, to the observed risk of cardiovascular events in a population-based cohort of patients with psoriasis. Patients with incident or prevalent adult-onset psoriasis aged 30–79 years without prior history of cardiovascular disease were included.Results. Among the 1197 patients with predicted risk scores, the median FRS was 6.0%, while the observed 10-year cardiovascular risk was 6.9% (standardized incidence ratio (SIR): 1.14; 95% confidence interval (CI): 0.92–1.42). The SIR was not elevated for women nor for men. The differences between observed and predicted cardiovascular risks in patients <60 years (SIR: 1.01; 95% CI: 0.73–1.41) or ≥60 years (SIR: 1.26; 95% CI: 0.95–1.68) were not statistically significant.Conclusion. There was no apparent difference between observed and predicted cardiovascular risks in patients with psoriasis in our study. FRS reasonably estimated cardiovascular risk in both men and women as well as in younger and older psoriasis patients, suggesting that FRS can be used in risk stratification in psoriasis without further adjustment.

Objective— Matrix gla protein (MGP) inhibits arterial and cartilaginous calcification. A threonine to alanine (Thr83Ala) polymorphism (codon 83) in MGP is associated with myocardial infarction and femoral artery calcification. We examined the association of the MGP Thr83Ala polymorphism with quantity and progression of coronary artery calcification (CAC), a noninvasive measure of subclinical coronary atherosclerosis. Methods and Results— In 605 participants of the Epidemiology of Coronary Artery Calcification Study, generalized linear mixed models were fit to determine the association of MGP Thr83Ala with CAC quantity and progression. There was a significant additive relation between MGP Thr83Ala and CAC progression ( P =0.001). In the fully adjusted model, every 1 Ala83 allele increase was associated with an estimated 1.9% (95% confidence interval, 0.7%–3.0%) per year since baseline larger increase in CAC quantity. A proxy single nucleotide polymorphism for MGP Thr83Ala (rs6488724) was similarly associated with CAC progression in an independent cohort from the Genetic Epidemiology Network of Arteriopathy (GENOA) study. Conclusion— Increased risk of myocardial infarction associated with MGP ThrAla83 genotype observed elsewhere may be related to faster progression of subclinical coronary atherosclerosis. MGP genotype could be a potential candidate for identifying individuals at increased risk of atherosclerotic disease who would benefit from aggressive primary prevention strategies.

ObjectivesTo examine the ability of standard and saturation transrectal prostate biopsy techniques to predict appropriate candidates for active surveillance.MethodsBetween 2005 and 2007, 500 consecutive patients underwent transrectal ultrasound‐guided biopsy by a standard template (12 cores) or saturation template (≥18 cores, median 27 cores), with subsequent radical prostatectomy. Using the criteria of Gleason score ≤6, clinical stage T1 or T2a, prostate‐specific antigen <10 and ≤33% of cores involved, 218 patients were potential candidates for active surveillance. Pathology results from the prostatectomy specimens were used to determine the accuracy of each biopsy technique. Biochemical failure after prostatectomy was evaluated using logistic and Cox proportional hazards regression.ResultsA standard biopsy was carried out for 124 patients and saturation biopsy for 94 patients. There was no statistically significant difference between the groups in terms of median age (P = 0.14), preoperative prostate‐specific antigen (P = 0.52) and clinical stage (P = 0.23). Similar rates of Gleason score ≥7 at the time of radical prostatectomy were found, with 14% for standard biopsy and 15% for saturation biopsy (P = 0.70). Upstaging was shown in two standard biopsy patients (1.6%) and no saturation biopsy patients (P = 0.62). A multivariate analysis adjusting for prior prostate biopsy, preoperative prostate‐specific antigen and clinical stage showed no difference in the rate of upgrading based on biopsy technique (P = 0.26). During follow up, 5‐year biochemical failure‐free survival estimates were not significantly different (P = 0.11).ConclusionsIn men with prostate cancer, standard and saturation transrectal prostate biopsies techniques are equally predictive of candidates for active surveillance.

BackgroundTo evaluate the impact of adjuvant hormonal therapy after radical prostatectomy on overall survival in high‐risk prostate cancer patients, stratified by comorbidity status.MethodsWe identified 1247 patients who underwent radical prostatectomy from 1988 to 2004 for high‐risk prostate cancer, as defined by National Comprehensive Cancer Network classification. Comorbidity status was stratified by Charlson Comorbidity Index as 0, 1 or >2, as well as by the presence or absence of cardiovascular disease. Overall survival was estimated by the Kaplan–Meier method, and compared within each comorbidity category/adjuvant hormonal therapy strata with the log–rank test.ResultsMedian patient age was 65 years, and the median postoperative follow up was 11.2 years. In total, 419 patients (34%) received adjuvant hormonal therapy. The distribution of Charlson Comorbidity Index was 0, 1 and ≥2 in 861 (69%), 244 (20%) and 142 (11%) patients, respectively. The 10‐year overall survival for patients who received adjuvant hormonal therapy versus those who did not was 75% versus 82% (P = 0.54) for patients with Charlson Comorbidity Index = 0, 72% versus 76% (P = 0.83) with Charlson Comorbidity Index = 1, and 70% versus 68% (P = 0.33) with Charlson Comorbidity Index ≥2. Meanwhile, 155 (12%) patients had cardiovascular disease, and the 10‐year overall survival for patients with cardiovascular disease who received adjuvant hormonal therapy was 72%, compared with 76% without adjuvant hormonal therapy (P = 0.97). On multivariate analysis, receipt of adjuvant hormonal therapy was not associated with non‐prostate cancer mortality (P = 0.24).ConclusionsAdjuvant hormonal therapy after radical prostatectomy for high‐risk prostate cancer does not increase non‐prostate cancer mortality, even among patients with multiple comorbidities. Additional studies are warranted to determine optimal multimodal treatment approach for high‐risk patients.

ObjectiveTo determine the incidence, time trends, risk factors, and severity of herpes zoster in a population‐based cohort of patients with newly diagnosed rheumatoid arthritis (RA) compared to a group of individuals without RA from the same population.MethodsAll residents of Olmsted County, Minnesota fulfilling for the first time the 1987 American College of Rheumatology criteria for RA between January 1, 1980 and December 31, 2007 and a cohort of similar residents without RA were assembled and followed by retrospective chart review until death, migration, or December 31, 2008.ResultsThere was no difference in the presence of herpes zoster prior to the RA incidence/index date between the cohorts (P = 0.85). During followup, 84 patients with RA (rate 12.1 cases per 1,000 person‐years) and 44 subjects without RA (rate 5.4 cases per 1,000 person‐years) developed herpes zoster. Patients with RA were more likely to develop herpes zoster than those without RA (hazard ratio [HR] 2.4 [95% confidence interval (95% CI) 1.7–3.5]). Herpes zoster occurred more frequently in patients diagnosed with RA more recently (HR 1.06 per year [95% CI 1.02–1.10]). Erosive disease, previous joint surgery, and use of hydroxychloroquine and corticosteroids were significantly associated with the development of herpes zoster in RA. There was no apparent association of herpes zoster with the use of methotrexate or biologic agents. Complications of herpes zoster occurred at a similar rate in both cohorts.ConclusionThe incidence of herpes zoster is increased in RA and has risen in recent years. There also has been an increasing incidence of herpes zoster in more recent years in the general population. RA disease severity is associated with the development of herpes zoster.
