- Objectives
The role of rheumatoid factor (RF) in vascular stiffness and cardiovascular risk in subjects without joint symptoms remains unclear. We investigated vascular stiffness in subjects without joint symptoms using pulse wave velocity (PWV), calculated Framingham risk scores (FRS), an estimator of cardiovascular risk, and analyzed whether vascular stiffness and FRS were affected by RF.
MethodsTwo hundred forty-two subjects were included in this population-based study. RF was quantified with turbid immunometry using a cut-off of RF > 15 IU/ml to denote RF positivity. Information was then obtained on joint symptoms. Brachial-ankle PWV (baPWV) was measured using an automated device.
ResultsOf the 242 subjects, 15 were RF-positive. RF-positive subjects without joint symptoms had a higher baPWV and FRS than RF-negative subjects without joint symptoms, but the difference did not reach statistical significance. However, when we stratified the subjects into two groups (group A – high RF: RF ≥ 40 IU/ml; group B – low RF: RF < 40 IU/ml), group A showed significantly higher baPWV (1640.7 ± 179.6 ㎝/s vs. 1405.7 ± 225.7 ㎝/s, P= 0.008) and FRS (25.7 ± 4.87 vs. 11.8 ± 9.6, P< 0.001). Multiple regression analysis was used to examine potential confounders, and RF exhibited significant but modest effects on baPWV (adjusted R-squared = 0.038, P= 0.030).
ConclusionsIn a sample of the general population without joint symptoms, higher levels of RF were associated with increased vascular stiffness, suggesting a pathophysiologic link between RF and endothelial dysfunction.

- Abstract
Objectives
Smoking is one of the most important leading causes of lung cancer. Smoking habit is recognized as nicotine dependence, which consists of physical and psychosocial dependence. To evaluate social nicotine dependence, the Kano Test for Social Nicotine Dependence (KTSND) working group developed a new questionnaire. We examined the social nicotine dependence among high school students, university students and patients with lung cancer.
Method
We applied Korean version of KTSND(KTSND-K) questionnaire to high school students, university students and patients with lung cancer. Complete data obtained from the 1333 responders were analyzed.
Results
Among the responders, current smokers, past-smokers, and never-smokers were 17.3%, 16.4%, and 66.3% respectively. According to smoking status, the total KTSND-K scores of current smokers were significantly higher than those of past-smokers, and of never-smokers (17.7±6.6 versus 13.7±5.7, and 10.9±5.15, P<0.001). The total KTSND-K scores of males were higher than those of females, suggesting that males have a propensity for depending nicotine socially much more than females (13.2±6.2 and 11.7±5.7 respectively, P<0.05). And the total KTSND scores of the patients with lung cancer, medical students, nursing students, and high school students were 11.2±3.8, 14.9±4.8, 14.6±5.8 and 15.6±5.9 respectively. The scores of patients with lung cancer were significantly lower than non-cancer people(P<0.01). Our study suggested that the KTSND-K questionnaire could be a useful method to evaluate psychosocial aspects of smoking in patients with lung cancer and non-cancer people.

- Abstract
Objective:
The ᅵink among carotid intimamedia thickness (IMT), vascular elastic property and the disease activity of systemic lupus erythematosus (SLE) is not well defined. We investigated the association between carotid atherosclerosis, elastic properties of the carotid arterial wall and clinical parameters of SLE.
Methods:
Fifty-one SLE patients and fifty healthy controls were included. Peak systolic global circumferential and posterior radial strains of carotid artery were measured to assess the elastic properties. Beta stiffness index was used as conventional method for the distensibility of the carotid artery. Information concerning SLE duration, cumulative dose of steroids and/or immunosuppressive drug intake was recorded, and SLE activity was assessed by SLE disease activity index (SLEDAI) score.
Results:
Carotid plaques were more common in SLE patients. SLE patients with plaques were 㢌der and showed the increased mean ᅵMT, high sensitivity C-reactive protein (hs CRP), IgG anti-cardi㢌ipin antibody (aCL), and longer disease duration compared with those without plaques. Peaksyst㢌ic global circumferential and posterior radial strain as well β stiffness index were significantly lower in SLE group. Age, disease duration, hsCRP, IgG aCL showed significant correlations with mean ᅵMT and parameters of carotid elastic property (all P's<0.05).
Conclusions:
Carotid atherosclerosis was more common in SLE patients, and carotid arterial stiffness had significant correlation with disease duration, hsCRP and IgG aCL level. Speckle tracking strain imaging is a comparative method for the assessment of elastic properties of carotid artery of SLE patients.
