ABSTRACT
Background@#Exercise capacity is known to be an independent predictor of cardiovascular events and mortality. However, most previous studies were based on Western populations.Further study is warranted for Asian patients according to ethnic or national standards. We aimed to compare prognostic values of Korean and Western nomograms for exercise capacity in Korean patients with cardiovascular disease (CVD). @*Methods@#In this retrospective cohort study, we enrolled 1,178 patients (62 ± 11 years;78% male) between June 2015 and May 2020, who were referred for cardiopulmonary exercise testing in our cardiac rehabilitation program. The median follow-up period was 1.6 years. Exercise capacity was measured in metabolic equivalents by direct gas exchange method during the treadmill test. The nomogram for exercise capacity from healthy Korean individuals and a previous landmark Western study was used to determine the percentage of predicted exercise capacity. The primary endpoint was the composite of major adverse cardiovascular events (MACE; all-cause death, myocardial infarction, repeat revascularization, stroke and hospitalization for heart failure). @*Results@#A multivariate analysis showed that the risk of primary endpoint was more than double (hazard ratio [HR], 2.20; 95% confidence interval [CI], 1.10–4.40) in the patients with lower exercise capacity (< 85% of predicted) by Korean nomogram. The lower exercise capacity was one of the strong independent predictors along with left ventricular ejection fraction, age, and level of hemoglobin. However, the lower exercise capacity by Western nomogram could not predict the primary endpoint (HR, 1.33; 95% CI, 0.85–2.10). @*Conclusion@#Korean patients with CVD with lower exercise capacity have higher risk of MACE.Considering inter-ethnic differences in cardiorespiratory fitness, the Korean nomogram provides more suitable reference values than the Western nomogram to determine lower exercise capacity and predict cardiovascular events in Korean patients with CVD.
ABSTRACT
Implant prostheses and removable partial dentures are mainly used as treatment methods for partial edentulous patients who have lost a number of teeth. The implant-assisted removable partial denture (IARPD) is strategically selected. The defect in maxillofacial structure due to osteomyelitis, a type of facial bone infection, causes dysfunction such as mastication, swallowing, and pronunciation, as well as social and psychological effects, so a removable restoration is required to restore the supporting tissue. Design of abutment and partial dentures is an essential factor in the success of treatment. In this case, IARPD, which has superior retention and stability compared to traditional removable partial dentures, can have a good prognosis. In a partial edentulous patient with bone defects due to osteomyelitis treatment, the stability of the denture was secured with IARPD restoration. Moreover, maintenance problem that may occur in the future was minimized by providing an appropriate denture design and occlusal scheme through several provisional restorations. This case can be expected to have a favorable prognosis in the long term.

ABSTRACT
Post-operative recurrence of cystic lesion is a great concern for clinician, patients, and their family, especially in case of odontogenic keratocyst, which has aggressive behavior and high recurrence rate. The purpose of this study was to evaluation clinical characters of OKC, focusing of the recurrence rate and proposed critical follow-up period. 58 cases (aged 9 to 66, 33 males and 25 females) of OKC were reviewed for sex of patients, location, size, operative procedure type, radiographic findings, histopathologic findings, post-operative recurrence time, from 2000 to 2005 at Yonsei Medical Center, were selected. The computerized statistical analysis was carried out with SAS system. 18 of 58 cases (31.03%) were recurred and this study revealed no statistically significant difference in recurrence rate for sex, location, size, radiographic findings, histopatologic findings, operative procedure type, recurrence timing. 3 out of 18 cases (16.7%) showed one or more recurrence. This was statistically significant difference (P=.0264). In this study, 15 of 18 cases (83.3%) were observed recurrence during 4 years after removal of the OKCs, we suggest critical follow-up period during 4 years after operation.

OBJECTIVE: The purposes of this study were to clarify the roles of personality characteristics and general psychopathology, including depression and hypochondriasis, in individuals with eating disorders, and to test a continuum hypothesis of eating disorders. METHODS: Using a multi-stage questionnaire sampling method including area sampling, proportionated stratified sampling, and quota sampling, we surveyed 3,062 subjects(1249 males and 1813 females) from a target of 4,400 Korean adults over the age of 18 in a nationwide area(9 ku's, 10 middle or small cities, and 17 kun's). We used the questionnaire which consisted of three parts:general information, scales for eating traits, and scales for personality characteristics and other general psychopathology. RESULTS: Psychoticism was the only personality characteristics which had a significant relationship with various eating traits including 'eating habits'(r=-0.3195), 'the Eating Attitudes Test'(EAT, r=0.3657), and 'preference for vegetables and fish, and dislike for sweet,tasting foods'(r=-0.2740). Lie scale also had a significant relationship with 'preference for snacks and instant foods'(r=-0.2117). These results were consistent in examining the relationships across genders. In female, there was a significant relationship between 'preference for the traditional Korean foods' and 'psychoticism'(r=-0.2103) in addtion to above relationships. However, there were no significant relationships between any of the eating traits and other psychopathology. Relative to the relationship between personality characteristics and general psychopathology, there were significant correlations between 'depression' and 'interoversion-extraversion'(r=-0.2174), 'depression' and 'neuroticism'(r=0.4510>, and 'hypochondriasis' and 'neuroticism'(r=0.3432). These correlations in female was the same as those of the total group, while among males, 'depression' was significantly correlated with all four personality characteristics, and 'hypochondriasis' was significantly correlated with 'interoversion-extraversion'(r=-0.2265) and 'neuroticism'(r=0.3762). CONCLUSION: These results suggest that psychoticism is the only personaltiy characteristics related to eating-specific psychopathology, while general psychopathology, such as depression and hypochondriasis is not related to eating pathology but may influence eating disorders by their interaction with other personality characteristics, such as interoversion-extraversion and neuroticism. Considering the results of previous studies in the patients with eating disorders and high risk groups, which are similar with our results in the general population, our results support a continuum hypothesis of eating disorders. Our results also suggest that gender differences in the pathology of eating disorders are the result not of difference in eating-specific pathology itself but through difference in influences of concurrent general psychopathology, such as depression and hypochondriasis.

OBJECTIVE: The authors attempted to investigate the relationship between depression and eating disorder or eating related problems through revealing the prevalence rate of eating problem and it's relationship to depressive tendency in athletic in athletic group which was considered as a high risk group fort eating disorders. METHODS: The subjects were 308 college athletes(Male: 187, Female: 121) and 477 college student controls(Male: 248, Female: 229). The authors used self-report questionnaire which was composed of epidemiologic data, eating habit scale, Eating Attitude Test(EAT), scale for locus of control for wieght, scale for food preference and eating behavior. And we also used Beck Depression Inventory of korean standadized edition for assessment of depression. RESULTS: 1) The eating habit of college athletes was better than that of college students, but the total score of the EAT related to abnormal eating behaviors and eating disorder in college athletes was higher than that in college students. In locus of control for weight, male athletes showed a similar trend with female athletes and college students, but they were different from male college students. And female athletes had a distinctive food preference or palatibility as like preference for cold and sour tasted food and vegetables. 2) The total scores of BDI in college athletes was higher than that in college students with the score highest in male athletes, among all the groups. The hypochondriacal tendency in male athletes was higher than that in male college students. 3) There were no significant correlation between eating habit and depression and between locus of weight control and depression in college athletes. But there was significant correlation between the score of EAT and BDI in male athletes. 4) In comparison with depressive group and non-depreressive group, there was no significant difference in eating habit, locus of weight control and hypochondriacal tendency but there was meaningful difference in the total score of the EAT. CONCLUSION: These results may suggest that athletes, especially female athletes, have higher prevalence rate of eating disorder or eating-related problems than college students. Eating problems were significantly related with depression in male athletes but not in female athletes. The difference may suggest that different strategy depending on the sex difference should be needed to manage the athletes with eating problems.
