TL;DR: Smoking emerged as a predictor of vascular events and should be strongly discouraged, and antiphospholipid antibodies and CRP support the role of inflammation and autoimmunity in the development of accelerated atherosclerosis in SLE.
Abstract: Objective
To determine the baseline (time 0) risk factors associated with the subsequent occurrence of vascular events in a multiethnic US cohort (LUMINA [LUpus in MInorities: NAture versus nurture]) of patients with systemic lupus erythematosus (SLE).
Methods
Five hundred forty-six LUMINA patients were assessed at time 0 for traditional and nontraditional (disease-related) risk factors for vascular events. These were defined as 1) cardiovascular (myocardial infarction and/or definite or classic angina and/or the undergoing of a vascular procedure for myocardial infarction [coronary artery bypass graft]), 2) cerebrovascular (stroke), and 3) peripheral vascular (arterial claudication and/or gangrene or significant tissue loss and/or arterial thrombosis in peripheral arteries). The observation time (followup time in the cohort) was the interval between time 0 and the last visit. The unit of analysis was the patient and not each vascular event. Variables at time 0 and vascular events were examined by univariable and multivariable (logistic and Cox proportional hazards regression) analyses. Age, sex, ethnicity, followup time, and all known risk factors for the occurrence of vascular events were included in the model.
Results
Thirty-four patients (6.2%) developed one or more vascular event after time 0. The overall median duration of followup in the cohort was 73.8 months (range 10.8–111.3 months). Vascular events (13 cardiovascular, 18 cerebrovascular, 5 peripheral vascular) occurred in 7 Hispanics from Texas (6.5%), 1 Hispanic from Puerto Rico (1.2%), 15 African Americans (7.5%), and 11 Caucasians (7.1%). The mean total number of traditional risk factors was significantly higher in patients who developed vascular events than in those who did not (7.1 versus 5.6). Independent predictors of vascular events were older age, current smoking status, longer followup time, elevated serum levels of C-reactive protein (CRP), and the presence of any antiphospholipid antibody. The same variables were identified when time-dependent analyses were performed, although azathioprine use was also found to be a contributing factor.
Conclusion
Smoking, previously not reported in SLE, emerged as a predictor of vascular events and should be strongly discouraged. Antiphospholipid antibodies and CRP support the role of inflammation and autoimmunity in the development of accelerated atherosclerosis in SLE. Ethnicity was not associated with vascular events in our patients.

TL;DR: To the authors' knowledge, this is the first report on the impact of ECS in a large series of patients treated for squamous cell carcinoma of the oral tongue at a single institution using surgery as the primary treatment modality.
Abstract: INTRODUCTION. The presence of nodal metastases remains the most significant predictive factor for regional recurrence and survival in patients treated for squamous cell carcinoma of the head and neck. Survival rates are further decreased in patients with nodal metastases that have spread beyond the lymph node capsule, or extracapsular spread (ECS). To the authors' knowledge, this is the first report on the impact of ECS in a large series of patients treated for squamous cell carcinoma of the oral tongue (SCCOT) at a single institution using surgery as the primary treatment modality. METHODS. The authors retrospectively reviewed the medical records of all patients treated for SCCOT with resection of the primary and neck dissection at a single institution between 1980 and 1995. RESULTS. Two hundred sixty-six patients were included in the study. Of that number, 146 patients (55%) were pathologically node-negative (pN0), 75 patients (28%) were pathologically node-positive (pN+) without ECS (pN+/ECS-), and 45 patients (17%) were pN+ with ECS (pN+/ECS+). The 5-year disease-specific and overall survival rates for pN0 patients were 88% and 75%; for pN+/ECS- patients, 65% and 50%; and 48% and 30% for pN+/ECS+ patients. The patterns of failure for the pN0, pN+/ECS- and, pN+/ECS+ groups showed overall recurrence rates of 19.8%, 34.2%, and 51.1% with regional failure rates of 11.5%, 19.2%, and 28.9%, respectively, and distant metastases rates of 3.3%, 8.2%, and 24.4%. CONCLUSIONS. ECS is the most significant predictor of both regional recurrence and development of distant metastasis accounting for decreased survival of patients with SCCOT in the current study. Therefore, intensive regional and systemic adjuvant therapy may be indicated for patients with ECS. Future studies should focus on identifying molecular mediators involved in ECS to determine targets for adjuvant therapies in this subset of patients.

TL;DR: Assessment of whether resistin could induce SMC proliferation and the mechanisms whereby resistin signals in SMCs are studied demonstrate that resistin induces HASMC proliferation through both ERK 1/2 and Akt signaling pathways.
Abstract: Background— Resistin, a novel adipokine, is elevated in patients with type 2 diabetes and may play a role in the vascular complications of this disorder. One recent study has shown that resistin has a proinflammatory effect on endothelial cells. However, there is no information on whether resistin could also affect vascular smooth muscle cells (SMCs). Thus, the purpose of this study was to assess whether resistin could induce SMC proliferation and to study the mechanisms whereby resistin signals in SMCs. Methods and Results— Human aortic smooth muscle cells (HASMCs) were stimulated with increasing concentrations of resistin for 48 hours. Cell proliferation was induced by resistin in a dose-dependent manner as assessed by direct cell counting. To gain more insights into the mechanism of action of resistin, we investigated the extracellular signal–regulated kinase (ERK) and/or phosphatidylinositol 3-kinase (PI3K) signaling pathways. Transient phosphorylation of the p42/44 mitogen-activated protein kinase (E...

TL;DR: A conceptual background for population-oriented interventions to promote informed decisions (IDM interventions) is provided, followed by a systematic review of studies of IDM interventions to promoting cancer screening and whether these interventions resulted in individuals participating in decision making at a desirable level.
