RESUMO
BACKGROUND AND AIM: Cancer survivors are gradually increasing, however, they suffer from various difficulties. We aimed to investigate the characteristics of cancer survivors and the effects of the services of the Korean Cancer Survivorship Center Pilot Project launched by the South Korean government on distress. METHODS: A prospective observational cohort study was performed on cancer survivors who completed primary treatment. Cancer survivors' distress and symptoms such as fatigue, pain, depressive mood, anxiety, and insomnia were evaluated by well-trained nurses. Regarding their needs, medical and psychosocial support services were provided. RESULTS: This study included 1,921 cancer survivors, with a mean age of 57.3 years (68.7% females). Breast cancer was most common, followed by stomach and colorectal cancer. Psychosocial and medical support decreased the percentage of the high-distress group from 50.9 to 30.5% and decreased the percentage of cancer survivors with high scores in fatigue, pain, anxiety, depressive mood, and insomnia. The independent predictors of a low distress level after the use of the services were older age, the relief of fatigue, pain, and insomnia. CONCLUSION: This study showed that psychosocial and medical support is associated with the lower distress and physical and mental symptoms of cancer survivors. Psychosocial and medical support could contribute to distress relief in cancer survivors. Further management strategies for fatigue, pain and insomnia are required.
RESUMO
BACKGROUND: High-sensitivity C-reactive protein (hs-CRP) is an important inflammatory marker, and inflammation is known to be involved in the initiation and progression of cancer. We investigated the association between serum hs-CRP levels and all-cause mortality, cancer mortality, and site-specific cancer mortality in apparently cancer-free Koreans. METHODS: A total of 33,567 participants who underwent routine check-ups at a single tertiary hospital health-screening center between May 1995 and December 2006, and whose serum hs-CRP level data were available, were included in the study. Baseline serum hs-CRP levels were obtained and subjects were followed up for mortality from baseline examination until December 31, 2008. RESULTS: During an average follow-up of 9.4 years, 1,054 deaths, including 506 cancer deaths, were recorded. The adjusted HRs (aHR; 95% confidence interval [CI]) of subjects with hs-CRP ≥3 mg/L for all-cause and cancer-related mortality were 1.38 (1.15-1.66) and 1.61 (1.25-2.07) in men, and 1.29 (0.94-1.77) and 1.24 (0.75-2.06) in women, respectively, compared with subjects with hs-CRP ≤1 mg/L. Elevated hs-CRP was also associated with an increased risk of site-specific mortality from lung cancer for sexes combined (2.53 [1.57-4.06]). CONCLUSIONS: This study suggests that elevated levels of hs-CRP in apparently cancer-free individuals may be associated with increased mortality from all-causes and cancer, in particular, lung cancer in men, but not in women. IMPACT: As a marker for chronic inflammation, hs-CRP assists in the identification of subjects with an increased risk of cancer death.

BACKGROUND: Participants' understanding of clinical trials is important in informed consent. However, little is known about what information participants really want to know. AIMS: To demonstrate the existence of a discrepancy between participants' understanding and their desire to know. METHODS: The participants in clinical trials at Seoul National University Hospital were surveyed. The survey consisted of 11 statements based on the essential elements of informed consent. The participants gave two responses to each statement on a five-point Likert scale to rate their subjective understanding and desire to know, respectively. Information discrepancy was defined as the difference between these two ratings: if understanding exceeded desire to know for a particular item, it was defined as 'over-informed'; if desire to know exceeded understanding for a particular item, it was defined as 'under-informed'. RESULTS: Participants reported good understanding of 'voluntariness', 'duration', 'study involves research' and poor understanding of 'confidentiality', 'compensation', 'benefits', 'procedures' and 'risks or discomforts'. For 'risks or discomforts', 'who to contact', 'voluntariness', 'duration' and 'procedures', participants reported high desire to know compared with 'confidentiality', 'purpose', 'study involves research' and 'benefits'. The elements 'study involves research', 'voluntariness', 'duration', 'purpose' and 'who to contact' were over-informed, while 'compensation', 'risks or discomforts', 'procedures', 'confidentiality' and 'benefits' were under-informed. Participants over 50 years of age, those without a college education and those whose participation was less voluntary were relatively less informed about the clinical trials. CONCLUSIONS: An information discrepancy was observed between the participants' understanding and their desire to know. By putting more emphasis on under-informed elements, the quality of informed consent could be improved.

Attending conferences is important for doctors and residents in family medicine. Nevertheless, departments of family medicine at many hospitals find it difficult to hold regular conferences. Holding joint videoconferences between Family Medicine Departments of several hospitals through a videoconferencing system could solve this problem. Therefore, Family Medicine Departments of Seoul National University Hospital, Seoul National University Bundang Hospital, and Kangwon National University Hospital decided to hold regular joint videoconferences via a videoconferencing system. Eighty-one joint videoconferences were held from April 1 to October 29, 2010. PowerPoint slideshows were transferred to the other two locations in the same resolution as presenter's monitor. Image and voice of the speaker were transferred in real time and in acceptable quality. Joint videoconferences are feasible, satisfactory and useful for medical education, especially when individual family medicine departments are small and lack resources to hold face-to-face conferences. We expect that more family medicine departments will choose to participate in implementing similar joint videoconferencing systems in the future.
RESUMO
OBJECTIVE: Smoking cessation leads to both beneficial and harmful changes in cardiovascular disease (CVD) risk factors. The basis of the harmful changes, however, is unknown. Our objective was to determine whether they are associated with the weight gain that accompanies smoking cessation. METHODS: Study subjects were male cigarette smokers aged at least 30 years who visited the Health Promotion Center of Seoul National University Hospital between 1995 and 2007 repeatedly with a 1- to 3-year interval between first and second visit. Self-reporting questionnaires gathered clinical and socio-economic characteristics on the initial visit, and CVD risk factors (blood pressure, fasting blood glucose, and serum lipid profile) were measured on both the visits. RESULTS: We compared the CVD risk factors between smoking quitters and smoking continuers. The quitters were more likely than the continuers to have harmful health changes such as increase in body weight (P<0.01), in systolic blood pressure, and in serum levels of total cholesterol, LDL-cholesterol, and non-HDL cholesterol (P<0.05). When stratified by body weight change, quitters who had gained more than the median (1.3 kg) were more likely than those who had not to have increase in blood pressure (P<0.01) and in serum levels of total cholesterol, triglycerides, non-HDL cholesterol, and fasting glucose (P<0.05). CONCLUSIONS: Harmful changes in CVD risk factors associated with smoking cessation were mainly secondary to weight gain. To reduce the risk of cardiovascular disease in quitters, therefore, more attention should be focused on preventing weight gain.
