Between April, 1986 and July, 1991, 477 patients underwent open heart surgery with hypothermic cardiopulmonary bypass. There were 242 patients [50.7%] of acyanotic congenital anomalies, 34 patients [7.1%] of cyanotic congenital anomalies, and 187 patients [39.2%] of acquired heart diseases, 8 patients [1.7%] of coronary artery diseases, and 6 patients [1.3%] of mixed anomalies. Among the 276 congenital cardiac anomalies, 147 patients [53.3%] were male and 129 patients [46.7%] were female, ranged in age from 2 years to 58 years. Among the 187 acquired heart diseases, 72 patients [38.5%] were male and 115 patients [61.5%] were female, ranged in age from 10 years to 68 years. The common congenital defect were VSD and ASD in acyanotic cardiac patients, and TOF in cyanotic cardiac patients. Among the 187 acquired heart diseases, 180 patients underwent operation for cardiac valvular diseases, 4 patients were resected left atrial myxoma, and 3 patients underwent operation for aortic regurgitation with ascending aortic aneurysm. The operative mortality rate was 1.2% in acyanotic cardiac patients, 11.8% in cyanotic cardiac patients, and 6.9% in acquired cardiac patients, with overall mortality rate 4.2%.

Objective : To measure the orientation of the facet joints of cervical spine (C-spine) segments in the sagittal plane, known as the pedicle-facet (P-F) angle, and to use these measurements to evaluate the relationship between the P-F angle and the amount of vertebral anterolisthesis in patients with degenerative cervical spondylolisthesis (DCS). Methods : A retrospective case-control study was performed including 30 age- and sex-matched patients with DCS and 30 control participants. Anterior-posterior and lateral view radiographs of the C-spine were obtained in a standing position. The P-F angle at all cervical levels and the amount of anterolisthesis at C4-5 were measured from lateral view plain radiographs. Results : The P-F angles at C4-5 were $141.14{\pm}7.14^{\circ}$ for the DCS group and $130.53{\pm}13.50^{\circ}$ (p=0.012) for the control group, and at C5-6 were $137.46{\pm}8.53^{\circ}$ for the DCS group and $128.53{\pm}16.01^{\circ}$ for the control group (p=0.001). The mean P-F angle at C4-5 did not correlate with the amount of anterolisthesis (p=0.483). The amount of anterior slippage did correlate with age (p<0.001). Conclusion : The P-F angle was intrinsically higher at C4-5, compared to C5-6, in both the DCS and control groups, which might explain the increased likelihood for anterolisthesis of C4. Higher P-F angles in the DCS group may be a predisposing factor to slippage. The P-F angle may interact with age to increase incidence of anterolisthesis with increasing age.

Purpose: The cardiopulmonary exercise test (CPET) is an important clinical tool for evaluating exercise capacity and is frequently used to evaluate chronic conditions including congenital heart disease. However, data on the normal CPET values for Korean children and adolescents are lacking. The aim of this study was to provide reference data for CPET variables in children and adolescents. Methods: From August 2006 to April 2009, 76 healthy children and adolescents underwent the CPET performed using the modified Bruce protocol. Here, we performed a medical record review to obtain data regarding patient' demographics, medical history, and clinical status. Results: The peak oxygen uptake ($VO_{2Peak}$) and metabolic equivalent ($MET_{Max}$) were higher in boys than girls. The respiratory minute volume $(V_E)/CO_2$ production ($VCO_2$) slope did not significantly differ between boys and girls. The cardiopulmonary exercise test data did not significantly differ between the boys and girls in younger age group (age, 10 to 14 years). However, in older age group (age, 15 to 19 years), the boys had higher $VO_{2Peak}$ and $MET_{Max}$ values and lower $V_E/VCO_2$ values than the girls. Conclusion: This study provides reference data for CPET variables in case of children and adolescents and will make it easier to use the CPET for clinical decision-making.

The purpose of this study is to identify the factors that may affect the 5-year survival of colon cancer through network model and to use it as a clinical decision supporting system for colorectal cancer patients. This study was conducted using data from 2,540 patients who underwent colorectal cancer surgery from 1996 to 2018. Eleven factors related to survival of colorectal cancer were selected by consulting medical experts and previous studies. Analysis was proceeded from the data sorted out into 1,839 patients excluding missing values and outliers. Logistic regression analysis showed that age, BMI, and heart disease were statistically significant in order to identify factors affecting 5-year survival of colorectal cancer. Additionally, a correlation analysis was carried out age, BMI, heart disease, diabetes, and other diseases were correlated with 5-year survival of colorectal cancer. Sex was related with BMI, lung disease, and liver disease. Age was associated with heart disease, heart disease, hypertension, diabetes, and other diseases, and BMI with hypertension, diabetes, and other diseases. Heart disease was associated with hypertension, diabetes, hypertension, diabetes, and other diseases. In addition, diabetes and kidney disease were associated. In the correlation analysis, the network model was constructed with the Network Correlation Coefficient less than p <0.001 as the weight. The network model showed that factors directly affecting survival were age, BMI levels, heart disease, and indirectly influencing factors were diabetes, high blood pressure, liver disease and other diseases. If the network model is used as an assistant indicator for the treatment of colorectal cancer, it could contribute to increasing the survival rate of patients.

Background: This study aimed to analyze the on heart rate, blood lactate concentration, packed cell volume (PCV) and hemoglobin (Hb) response after conducting exercise in endurance horses. Methods: A total of 20 healthy 3-9-years-old Jeju crossbreed mares ($5.95{\pm}2.24$ year) of age and $312.65{\pm}13.59kg$ of weight) currently participating the endurance competition were used. The field tests selected for the experiment was gallop (approximately 8.3 m/s) along the selected 2.5 km course (a natural forest trail, not artificial road; a closed loop course). The horses were divided into three groups according to their age; 3-4 years of age (G1, $3.29{\pm}0.49$ year), 6-7 years of age (G2, $6.42{\pm}0.53$), and 8-9 years of age (G3, $8.50{\pm}0.55$). The measurements times for the heart rate, blood lactate concentration, PCV, and Hb analysis were conducted before exercise (T0), shortly after exercise (T1), 15 min after exercise (T2), and 30 min after exercise (T3), respectively. Data was analyzed using an analysis of covariance (ANCOVA) for repeated measures with times and groups. Results: The results of the comparison depending on the passage of rest time after exercise suggest that the heart rate and blood lactate concentration of three groups at T2 significantly decreased compared to T1 (p < 0.001). PCV of the G2 and G3 groups were significantly decreased at T2 compared to T1 (p < 0.01). Hb values at G2 (p < 0.01) and G3 (p < 0.001) groups were significantly decreased at T2 as compared to T1. However, heart rate, blood lactate concentration, PCV and Hb level at T1 showed no difference in the comparison of horses from different age groups with the exception of G3 group in terms of heart rate. Conclusion: The physiologic and hematological responses of horses during recovery time after 2,500 m exercise with gallop were no significant difference among the groups. These data are useful as a response evaluation method for training of endurance horses.

Purpose: The purpose of this study was to examine a combined influence of obesity and metabolic syndrome on ischemic heart disease in Korean middle aged and older adults. Methods: This study used secondary data from the 2013 Korea National Health and Nutrition Examination Survey. A total of 3,726 adults over age 40 were included. Logistic regression was used for analysis of complex samples. Gender, age, educational level, family income, family history of ischemic heart disease, physical activity, smoking, and heavy alcohol consumption were analyzed as covariates. Results: Ischemic heart disease was more prevalent among adults with metabolic syndrome regardless of obesity (non-obesity: Adjusted Odds Ratio [AOR]: 3.044, 95% Confidence Interval [CI]: 1.163-7.967, overweight: AOR: 2.805, 95% CI: 1.246-6.316, obese: AOR: 3.137, 95% CI: 1.548-6.358) compared to the reference group, defined as adults with non-obesity and non-metabolic syndrome. Odds of ischemic heart disease were not significant in the group with obesity and non-metabolic syndrome compared to the reference group. Conclusion: The results of this study show that the population with metabolic syndrome is an at-risk group for ischemic heart disease. Thus, management of metabolic syndrome is required for prevention of ischemic heart disease.

Background and Objectives: For adult men with congenital heart disease (ACHD), data on erectile dysfunction (ED) is limited. We aimed to assess the frequency of ED, its role in patient-physician communication and to identify parameters predicting ED. Methods: Male ACHD ≥18 years registered at the German National Register for Congenital Heart Defects were invited to participate in an online questionnaire about sexual health. Participants with presumed ED according to International Index of Erectile Function Score were compared to patients without ED. Results: The 371 patients responded to the questionnaire (83% with moderate to highly complex ACHD). The 43% presented with more than mild ED. When ED was present, patients complained about general anxiety to be sexually active more often (p<0.05) and underwent sexual activity less frequently compared to those without ED (p<0.05). Age ≥40 years (odds ratio [OR], 3.04; p=0.002), being single (OR, 6.82; p<0.0001), anxiety to be sexually active (OR, 2.64; p=0.0002) and psychiatric disease (OR, 4.33; p<0.0007) emerged as independent predictors for ED. Overall, patients sought medical advice in 6.7% of cases, whilst 29.6% would appreciate an active approach by the physician to address this sensitive topic. Conclusions: ED is affecting one third to one half of male ACHD according to a questionnaire-based analysis. Older age, being single, fear of sexual activity due to ACHD and psychiatric disorder emerged as independent predictors for ED. These parameters can easily be assessed to identify patients at risk. ED should be addressed proactively by health professionals.

Patients over 15 years of age who have undergone a surgical correction of congenital heart disease at Kyungpook University Hospital during the period of January 1990 through October 1994 have been reviewed . One hundred forty three, 22.4 % of 628 operations, which have repaired congenital heart diseases during this period were adult patients. There were 23 patients under 20 years of age, 58 between 20∼29 years, 34 between 30∼39 years, 18 between 40∼49 years, and 10 between 50∼59 years. The most common defects were atrial septal defects which accounted for 73 cases (51.1 %) and other common anomalies were ven- tricular septal defects (57 cases, 39.9 %), tetralogy of Falloffs(4 cases, 2.8%) in order of incidence. There were 10 non-fatal operative complications (6.9 %) but there was no operative mortality. This study shows the incidence of operable congenital heart diseases in adults and the fact that it could be corrected surgically with low mortality and morbidity.

This study was to know the effects of massage on the back region in order to reduce stress in middle age women. To investigate the effects of massage to the stress levels of middle aged women, we evaluated blood pressure (BP), heart rate variability (HRV), and ultrasonography before and after back massage. The blood pressure after massage was reduced when compared to that of pre-massage. The HRV spectrum analysis was used Frequency domain analysis such as Mean HRV, normalized low frequency (norm LF), norm high frequency (norm HF), and LF/HF ratio. Post-massage BP tended to be low, but not statistical significant. After Massage, the Mean HRV, norm LF, and LF/HF ratio were significantly reduced, while norm HF was significantly increased as compared with pre-massage. The muscle layer and fat layer were significantly diminished by massage. The study was suggested that massage may be an effective treatment for relief of stress.

Backgrounds: Dog bite is the most common cause of animal bites. This study was conducted to analyze dog bite patients and to compare the differences of groups based on age. Methods: We performed a retrospective analysis of patients admitted to our hospital after dog bite injuries from January 2003 through December 2004. The patients were divided into two groups based on age; group A (children, < 15 years) and group B (adult, ${\geq}15years$). Results: A total of 103 patients were enrolled in the study. Dog bite injury frequently occurred to children under 10 years of age (21%). Home was the most common place of dog bite in group A, but public place was the most common in group B (p=0.000). Face was the most frequent body region of dog bite in group A, but hand was the most frequent in group B (p=0.039). Conclusions: From this study, we found statistically significant differences between the groups. Knowledge about age-related characteristics could result in improved prevention and treatment of these injuries.
