  • Background: Single nucleotide polymorphisms of C-reactive protein (CRP) have been shown to be related to circulating CRP level, risk and prognosis in cancer patients. However, accumulating evidence of rs1800947 involvement in risk of cancer is inconsistent. Thus, a meta-analysis was performed to obtain a more precise relationship. Materials and Methods: The pooled odds ratio (OR) and its 95% confidence interval were assessed in 10 eligible articles with 12 studies containing 5,601 cancer cases and 8,669 cancer-free controls. Results: No significant association was observed overall and in subgroups in comparison of genotype GC vs GG ($P_H$=0.847, OR=0.939, 95%CI=0.810-1.087), GC/CC vs GG ($P_H$=0.941, OR=1.021, 95%CI=0.901-1.157) and allele C vs G ($P_H$=0.933, OR=1.026, 95%CI=0.909-1.159). However, statistically significance was evident in comparison of genotype CC vs GG in cancer risk ($P_H$=0.586, OR=2.854, 95%CI= 1.413-5.763), especially in colorectal cancer ($P_H$=0.481, OR=4.527, 95%CI= 1.664- 12.315). Conclusions: Genotype CC of rs1800947 in the CRP gene is strongly associated with increased cancer risk, particularly in colorectal cancer.

  • Objectives: The purpose of this study was to comprehensively examine the relationship between periodontal disease and high-sensitivity C reactive protein (hs-CRP) level. Methods: This study was conducted using the data from the sixth Korea National Health and Nutrition Examination Survey. SPSS 18.0 for Windows was used for statistical analysis. The data were collected from 4,576 subjects aged ≥19 years. To analyze the association between periodontal disease and hs-CRP level, chi-squared test and logistic regression analysis were used. Results: Consequent to correcting all the disturbance variables, the moderate risk of hs-CRP was 1.39 times higher in patients with periodontal disease than in those without (OR=1.39; 95% CI:1.14-1.69), whereas the high risk of hs-CRP was 1.10 times but there was no statistical significance (OR=1.10; 95% CI:0.79-1.53). Conclusions: Periodontal disease contributes to raising the risk of systemic inflammation and hs-CRP from low to moderate. Periodontal disease is associated with an early rise in hs-CRP.

  • Background: Associations between elevated C-reactive protein (CRP) and cancer risk have been reported for many years, but the results from prospective cohort studies remains controversial. A meta-analysis of prospective cohort studies was therefore conducted to address this issue. Methods: Eligible studies were identified by searching the PubMed and EMBASE up to October 2012. Pooled hazard ratios (HR) was calculated by using random effects model. Results: Eleven prospective cohort studies involving a total of 194,796 participants and 11,459 cancer cases were included in this meta-analysis. The pooled HR per natural log unit change in CRP was 1.105 (95% confidence interval (CI): 1.033-1.178) for all-cancer, 1.308 (95% CI: 1.097-1.519) for lung cancer, 1.040 (95% CI: 0.910-1.170) for breast cancer, 1.063 (95% CI: 0.965-1.161) for prostate cancer, and 1.055 (95% CI: 0.925-1.184) for colorectal cancer. Dose-response analysis showed that the exponentiated linear trend for a change of one natural log unit in CRP was 1.012 (95% CI: 1.006-1.018) for all-cancer. No evidence of publication bias was observed. Conclusions: The results of this meta-analysis showed that the elevated levels of CRP are associated with an increased risk of all-cancer, lung cancer, and possibly breast, prostate and colorectal cancer. The result supports a role of chronic inflammation in carcinogenesis. Further research effort should be performed to identify whether CRP, as a marker of inflammation, has a direct role in carcinogenesis.

  • Objective: Growing evidence suggests that increased cardiovascular disease (CVD) risk is associated with female infertility caused by conditions such as polycystic ovarian disease, obesity, thyroid dysfunction, and endometriosis. The aim of this study was to evaluate whether any relationship exists between CVD and unexplained infertility. Methods: Sixty-five women with unexplained infertility and 65 fertile controls were enrolled in the study. CVD risk markers such as low-density lipoprotein (LDL), high-density lipoprotein (HDL), total cholesterol (TC), triglycerides (TG), insulin resistance (defined by the homeostasis model assessment ratio), and high-sensitivity C-reactive protein (hs-CRP) were assessed. Results: TG, TC, LDL, and hs-CRP levels were higher and HDL levels were lower in patients with unexplained infertility than in fertile controls (p<0.05 for all). Positive associations were found between unexplained infertility and TG, TC, LDL, and hs-CRP levels, and a negative correlation was found for HDL (p<0.05 for all). Multivariate logistic regression analysis showed that TG, HDL, and hs-CRP were independent variables associated with unexplained infertility. Conclusion: Our study showed that women with unexplained infertility had an atherogenic lipid profile and elevated hs-CRP levels, suggesting a higher risk of developing CVD in the future. Further studies with larger groups are needed to investigate the nature of this link.

  • Purpose: The purpose of this study was to determine the effects of different intensity of aerobic exercise for four weeks on cardiovascular risk factors, reactive oxygen, and antioxidant enzymes in old mice. Methods: Eighteen male C57BL/6 mice age 18 months were randomly classified into the control group (n= 6), the moderate intensity exercise group (n= 6), and the low intensity exercise group (n= 6). The training groups performed the aerobic exercise twice daily for 20 minutes, five days weekly for four weeks. Data were analyzed using descriptive statistics, analysis of variance (ANOVA), the Chi-square test, and the Tukey's test with the SPSSWIN 21.0 program. Results: In this study, among the risk factors of cardiovascular disease, blood sugar (BS) (p= .023) and total cholesterol (TC) (p= .001) were significantly different between the moderate intensity exercise group and the control group. Additionally, there were significant differences in the reactive oxygen malondialdehyde (MDA) (p= .001), the antioxidant enzymes superoxide dismutase (SOD) (p< .001) and glutathione reductase (GR) (p= .015) between the moderate intensity exercise group and the control group. Conclusion: This finding suggests that moderate intensity aerobic exercise promotes the activity of antioxidant enzymes and lowers cardiovascular risk factors in older mice.

  • With the development in field of industry and medicine, new machines and techniques are being launched. Moreover, the complexity of the techniques is associated to an increasing risk of incident. Especially, a small error in radiotherapy can lead to a serious patient-related incident, risk management is necessary in radiotherapy in order to reduce the risk of incident. However, in field of radiotherapy, there are no legally binding clauses for risk management and there is an absence of risk management systems at an institutional level. Therefore, we analyzed institutional status of risk management, reporting & classification systems, and risk assessment & analysis in 31 countries. For risk management and reporting systems, 65% of countries investigated had legislation or regulations; however, only 35% of countries used classification systems. It was found that 43% more countries had legislation for risk management in healthcare than those for radiotherapy; 19% more countries had reporting systems for healthcare than those for radiotherapy. For classification systems, 60% more countries had legislation, recommendation, and guidelines in the field of radiotherapy than those for healthcare. Recently, international institutes have published several reports for risk management and patient safety in radiotherapy, owing to which, countries adopting risk management for radiotherapy will gradually increase. Before adopting risk management in Korea, we should precisely understand the procedures and functions of risk management, in order to increase efficiency of risk management because classification & reporting system and risk assessment & analysis are connected organically, and institutional management is needed for high quality of risk management in Korea.

  • BACKGROUND/OBJECTIVES: High sensitivity C-reactive protein (hsCRP) is a strong independent predictor of future cardiovascular disease (CVD) risk. We evaluated the relationship between hsCRP and dietary intake in apparently healthy young women living in southern Vietnam. SUBJECTS/METHODS: Serum hsCRP was measured and dietary intake data were obtained using the 1-day 24-hour recall method in women (n = 956; mean age, $25.0{\pm}5.7$ years) who participated in the International Collaboration Study for the Construction of Asian Cohort of the Korean Genome and Epidemiology Study (KoGES) in 2011. RESULTS: Women in the high risk group (> 3 mg/L) consumed fewer fruits and vegetables, total plant food, potassium, and folate than those in the low risk group (< 1 mg/L). A multiple regression analysis after adjusting for covariates revealed a significant negative association between hsCRP and fruit and vegetable consumption. A logistic regression analysis showed that the odds ratio (OR) of having a high hsCRP level in women with the highest quartiles of consumption of fruits and vegetables [OR, 0.391; 95% confidence interval (CI), 0.190-0.807], potassium [OR, 0.425; 95% CI, 0.192-0.939] and folate [OR, 0.490; 95% CI, 0.249-0.964] were significantly lower than those in the lowest quartiles. CONCLUSIONS: These results suggest that, in young Vietnamese women, an increased consumption of fruit and vegetables might be beneficial for serum hsCRP, a risk factor for future CVD events.

  • Recent studies suggest a possible pathogenic linkage between the osteoporosis and atherosclerosis. We investigated the relationship between cardiovascular risk factors, including high sensitivity C-reactive (hs-CRP), hs-CRP and bone metabolism in females. Anthropometric measurements were performed on 300 women, and cardiovascular risk factors, including fasting blood glucose, lipid profiles and hs-CRP. An atherogenic index was calculated using the serum total cholesterol level divided by the high-density lipoprotein cholesterol level. The lumbar spine bone mineral density was measured using dual X-ray abosorptiometry. By bivariate analysis, the lumbar spine BMD showed negative correlations with age, systolic and diastolic blood pressures, serum total cholesterol, high-density lipoprotein cholesterol. The Age, BMI and high-density lipoprotein cholesterol showed significant correlations with the lumbar spine BMD. From linear regression analyses of all the study subjects, age, high-density lipoprotein cholesterol were found to be determinants of the lumbar spine BMD($R^2=0.272$).

  • Objectives : This study was performed to assess the association between high sensitivity C-Reactive Protein (hsCRP) and hypertension. Methods : We evaluated the relationship between hsCRP with hypertension and other cardiovascular risk factors, using a cross-sectional survey of 202 people over the age of 50, living in a rural area. A logistic regression analysis was used to study the association between hsCRP and hypertension. The hsCRP levels were divided in quartiles, and the odds ratios (OR), with 95% confidence intervals (95% CI), calculated, using the lowest quartile as a reference. Results : The subjects consisted of 37.1% men and 62.9% women, with a mean (SD) hsCRP level of $1.9({\pm}3.0mg/{\ell})$ . The overall prevalence of hypertension was 61.4%. The prevalence of hypertension according to the hsCRP quartile was not statistically significant. After adjustment for confounding variables, the prevalence of hypertension according to the subjects in the 2nd, 3rd and 4th hsCRP quartiles were 1.418 (95% CI=0.554-3.628), 1.124 (95% CI=0.392-3.214) and 0.892 (95% CI=0.312-2.547) times higher, respectively, compared to those in the 1st quartile. Conclusions : The results showed that the level of hsCRP was not a risk factor for hypertension among adults aged over 50 years, living in a rural area. A further study should be performed to find the association between hsCRP and hypertension.

  • Background and Objectives: Both neutrophil to lymphocyte ratio (NLR) and C-reactive protein (CRP) are biomarkers associated with poor prognosis of patients with acute myocardial infarction (AMI). However, the combined usefulness of NLR and CRP in predicting adverse outcomes has not been investigated. Subjects and Methods: We analyzed 381 consecutive AMI patients who underwent percutaneous coronary intervention (PCI) from January 2012 to January 2014. The endpoints were all-cause mortality, recurrent myocardial infarction (MI), stent thrombosis, repeat revascularization, stroke, and major adverse cardiac and cerebrovascular events (MACCE) at 2-year follow-up. Included patients were divided into 4 groups according to the optimal cut-off values for NLR and CRP on receiver operating characteristic analysis predicting mortality. Results: Patients with both high NLR (>6.30) and high CRP (>0.76) had significantly greater risk of all-cause death and MACCE at 24 months, with no significant increase in the risk of recurrent MI, stent thrombosis, or stroke compared with patients with either low NLR or low CRP, as well as those with low NLR and low CRP. Kaplan-Meier analysis revealed significantly lower survival in patients with high NLR-CRP. On Cox multivariate analysis, high NLR-CRP (hazard ratio 23.172, 95% confidence interval 6.575 to 81.671, p<0.001) was an independent predictor of all-cause death. Conclusion: Elevated levels of both NLR and CRP are associated with increased risk of long-term mortality in AMI patients who have undergone PCI.
