Background: Middle-aged cancer survivors lack specific health guidelines compared to young and old cancer survivors. Their increased prevalence necessitates the establishment of tailored health guidelines. This study aimed to investigate the health-related behaviors of middle-aged cancer survivors compared to those of the general population. Methods: This cross-sectional study analyzed 17,332 adults aged 40–65 years who participated in the sixth and seventh Korea National Health and Nutrition Examination Survey (2013–2018). Data on cancer screening, alcohol consumption, smoking, physical activity, sedentary time, and dietary management were collected via self-reported questionnaires. Propensity score matching (1:5) revealed 591 middle-aged cancer survivors and 2,955 non-cancer controls. Descriptive statistics, chi-square tests, and logistic regression analyses were conducted to compare the demographic characteristics and health-related behaviors of both groups. Results: Multivariate analysis revealed that middle-aged cancer survivors were significantly less likely to consume alcohol (odds ratio [OR]: 0.64; 95% confidence interval [CI]: 0.51–0.81) and smoke (OR: 0.65; 95% CI: 0.43–0.99) and more likely to engage in aerobic physical activity (OR: 1.33; 95% CI: 1.08–1.64) and practice dietary management (OR: 1.47; 95% CI: 1.17–1.84) than the non-cancer controls. However, no significant differences in cancer screening adherence and sedentary time were observed between both groups. Conclusions Overall, this study provides fundamental data for the development of tailored health guidelines and patient education programs for cancer survivors.

OBJECTIVE: To evaluate the effects of cardiac rehabilitation (CR) on functional capacity in obese and non-obese patients who have suffered acute myocardial infarction (AMI). METHODS: Overall, 359 patients who have suffered AMI, and were referred for CR after percutaneous coronary intervention from 2010 to 2015 and underwent an exercise tolerance test before and after phase II CR were included in this study. The patients were divided into two groups: obese group with body mass index (BMI) ≥25 kg/m² (n=170; age, 54.32±9.98 years; BMI, 27.52±2.92 kg/m²) and non-obese group with BMI <25 kg/m² (n=189; age, 59.12±11.50 years; BMI 22.86±2.01 kg/m²). The demographic characteristics and cardiopulmonary exercise capacity of all patients were analyzed before and after CR. RESULTS: There were significant changes in resting heart rate (HR(rest)) before and after CR between the obese and non-obese groups (before CR, p=0.028; after CR, p=0.046), but other cardiopulmonary exercise capacity before and after CR was not different between the groups. HR(rest) (p<0.001), maximal metabolic equivalents (METs, p<0.001), total exercise duration (TED, p<0.001), and maximal oxygen consumption (VO(2max), p<0.001) improved significantly in the obese and non-obese groups after CR. No difference in the change in the cardiopulmonary exercise capacity rate was detected between the groups. CONCLUSION: CR may improve functional capacity in patients who suffered AMI regardless of their obesity.

PURPOSE: Grinding with less stress on 3Y-TZP through proper selection of methods and instruments can lead to a long-term success of prosthesis. The purpose of this study was to compare the phase transformation and physical properties after zirconia surface grinding with 3 different grinding burs. MATERIALS AND METHODS: Forty disc-shaped zirconia specimens were fabricated. Each Ten specimens were ground with AllCeramic SuperMax (NTI, Kahla, Germany), Dura-Green DIA (Shofu Inc., Kyoto, Japan), and Dura-Green (Shofu Inc., Kyoto, Japan). Ten specimens were not ground and used as a control group. After the specimen grinding, XRD analysis, surface roughness test, FE-SEM imaging, and biaxial flexural strength test were performed. RESULTS: After surface grinding, small amount of monoclinic phase in all experimental groups was observed. The phase change was higher in specimens, which were ground with Dura-Green DIA and AllCeramic SuperMax burs. The roughness of surfaces increased in specimens, which were ground with Dura-Green DIA and AllCeramic SuperMax burs than control groups and ground with Dura-Green. All experimental groups showed lower flexural strength than control group, but there was no statistically significant difference between control group and ground with Dura-Green DIA and AllCeramic SuperMax burs. The specimens, which were ground with Dura- Green showed the lowest strength. CONCLUSION: The use of dedicated zirconia-specific grinding burs such as Dura-Green DIA and AllCeramic SuperMax burs decreases the grinding time and did not significantly affect the flexural strength of zirconia, and therefore, they may be recommended. However, a fine polishing process should be accompanied to reduce the surface roughness after grinding.

PURPOSE: This study was conducted to obtain difference in fracture strength according to the diameter of one-body O-ring-type of mini implant fixture, to determine the resistance of mini implant to masticatory pressure, and to examine whether overdenture using O-ring type mini implant is clinically usable to maxillary and mandibular edentulous patients. MATERIALS AND METHODS: For this study, 13 mm long one body O-ring-type mini implants of different diameters (2.0 mm, 2.5 mm and 3.0 mm) (Dentis, Daegu, Korea) were prepared, 5 for each diameter. The sample was placed at 30degrees from the horizontal surface on the universal testing machine, and off-axis loading was applied until permanent deformation occurred and the load was taken as maximum compressive strength. The mean value of the 5 samples was calculated, and the compressive strength of implant fixture was compared according to diameter. In addition, we prepared 3 samples for each diameter, and applied loading equal to 80%, 60% and 40% of the compressive strength until fracture occurred. Then, we measured the cycle number on fracture and analyzed fatigue fracture for each diameter. Additionally, we measured the cycle number on fracture that occurred when a load of 43 N, which is the average masticatory force of complete denture, was applied. The difference on compressive strength between each group was tested statistically using one-way ANOVA test. RESULTS: Compressive strength according to the diameter of mini implant was 101.5 +/- 14.6 N, 149 +/- 6.1 N and 276.0 +/- 13.4 N, respectively, for diameters 2.0 mm, 2.5 mm and 3.0 mm. In the results of fatigue fracture test at 43 N, fracture did not occur until 2x106 cycles at diameter 2.0 mm, and until 5x106 cycles at 2.5 mm and 3.0 mm. CONCLUSION: Compressive strength increased significantly with increasing diameter of mini implant. In the results of fatigue fracture test conducted under the average masticatory force of complete denture, fracture did not occur at any of the three diameters. All of the three diameters are usable for supporting overdenture in maxillary and mandibular edentulous patients, but considering that the highest masticatory force of complete denture is 157 N, caution should be used in case diameter 2.0 mm or 2.5 mm is used.
