Purpose: This study was conducted to assess how extreme obesity affects 30-day mortality in this patient group. Methods: A total of 802 patients who underwent emergency gastrointestinal surgery from January 2007 to December 2017 were retrospectively reviewed. Patients were divided into three groups according to their body mass index (BMI): group 1, normal weight (BMI: $18.5{\sim}22.9kg/m^2$); group 2, overweight (BMI: $23.0{\sim}29.9kg/m^2$ ); and group 3, obesity ($BMI{\geq}30kg/m^2$). Patients with a BMI under 18.5 were excluded from the analysis. Chi-squared test, Fisher's exact test, Kaplan-Meier survival analysis, and the log-rank test were used to assess and compare 30-day mortality rates between groups. Results: The mortality rates of group 1, group 2, and group 3 were 11.3%, 9.0%, and 26.9%, respectively (P<0.017). The mortality rate did not differ significantly between group 1 and 2 (11.3% vs. 9.0%; P=0.341), but group 1 and 2 showed better survival rates than group 3 (11.3% vs. 26.9%; P=0.028, 9.0% vs. 26.9%; P=0.011). Kaplan-Meier survival analysis revealed that group 3 had higher mortality than the other two groups (P=0.001). Conclusion: Obesity ($BMI{\geq}30kg/m^2$) was one of the risk factors influencing critically ill patients who underwent emergency surgery.

Objectives: This study sought to investigate the association between the systemic intake of proton pump inhibitors (PPI) and the early failure of dental implants. Materials and Methods: A retrospective cohort study involving 1,918 dental implants in 592 patients (69 implants in 24 PPI users and 1,849 implants in 568 nonusers, respectively) was conducted. The effect of PPI intake on the osseointegration of dental implants was evaluated using patientand implant-level models. Results: Among 24 PPI users, two patients experienced implant failure, one of whom had three and the other of whom had one failed implant, respectively. Thus, the rate of failure for this population was 8.3%. Separately, 11 nonusers each experienced one implant failure, and the failure rate for these patients was 1.9%. Fisher's exact test revealed statistically significant differences between PPI users and nonusers at the implant level (P=0.002) but failed to show any significance at the patient level (P=0.094). The odds of implant failure were 4.60 times greater among PPI users versus nonusers. Dental implants that were placed in patients using PPIs were found to be 4.30 times more likely to fail prior to loading. Conclusion: The findings of this study suggest that PPI intake may be associated with an increased risk of early dental implant failure.

Purpose: This study aimed to develop an integrated health promotion program for cancer survivors residing in the community based on the shared care model, and evaluate its effectiveness. Methods: A quasi-experimental trial was conducted. The participants consisted of 35 cancer survivors with completed intensive cancer therapy at the cancer hospital. The intervention group (n=20) and the control group (n=15) were recruited from among a district home cancer patient registrations. The intervention group participated in an integrated health promotion program based on the MAPP (Mobilizing for Action through Planning and Partnership) development process. The program consisted of physical, psycho-social and body image units. The participants were assessed before the program, and immediately after the program. Data were collected between July 1 and September 2, 2018 using FACT-G quality of life (QOL), distress thermometer (DT), and resilience. The data were analyzed by performing a χ2 test, Fisher's exact test, Mann-Whitney test, and ranked ANCOVA using SPSS. Results: The intervention group reported a higher QOL overall and significantly higher social/family well-being than the control group. Distress was significantly lower in intervention group than in the control group. Resilience had no significant difference between the two groups. Conclusion: These findings indicate that the integrated health promotion program base on the shared care model and MAPP development process could be effective intervention for improving social/family well-being and the QOL, and reducing distress of cancer survivors at home. Community health center nurses need to provide intervention to support self-care competency for cancer survivors' comprehensive care with physical, psycho-social, and body image to help them adjust their life to a moderate risk group in the community.

Purpose: The primary purpose of this study was to investigate the effects of cervical stabilization exercise (CSE) on hamstring flexibility in patients with neck pain. A secondary purpose of this study was to investigate the effects of cervical range of motion (CROM) and craniovertebral angle (CVA). Methods: This study was a single-blind, randomized, comparative trial. Twenty patients were allocated into either the cranio-cervical flexion exercise (CCFE) group or the CSE group. Before and after the intervention, we measured straight leg raise (SLR), popliteal angle (PA), CROM, and CVA in the sitting and standing positions. Fisher's exact test, the Mann-Whitney test, and Wilcoxon's signed-rank test were used to analyze our data. Results: Both groups showed significant improvements in the value of SLR, PA, cervical extension, cervical rotation, and CVA in the standing position (both, p<.05) after intervention. However, only the CSE group showed significant improvements in cervical right lateral flexion (z=-2.209; p<.01) and cervical left lateral flexion (z=-2.537; p<.05) after intervention. The CSF group showed more significant improvements in SLR, PA, both cervical lateral flexions, and both cervical rotations than the CCFE group. Conclusions: The results of this study will guide future research in identifying the effectiveness of CSE. In conclusion, it can be inferred that CSE has a positive effect on SLR, PA, CROM, and CVA in the standing position in patients with chronic neck pain.

Purpose: The purpose of this study is to confirm the effect of static stretching of the plantar flexor for 5 minutes on balance and ankle muscle activity when walking in young adults. Methods: This study experimented on 20 healthy college students without vestibular and musculoskeletal diseases. Subjects performed static stretching intervention of plantar flexor for 5 minutes on a stretch board set at 15° to 25° Balance was measured four times before intervention (pre), after intervention (post), 5 minutes after intervention (post 5 min), 10 minutes after intervention (post 10 min), and ankle muscle activity was measured during walking. For the analysis and post hoc analysis, one-way Repeated Measure ANOVA and Fisher's LSD (Last Significant Difference) was performed to find out the change in balance and the activity of ankle muscles before static stretching, pre, post, post 5 minutes rest, post 10 minutes rest. Results: There was no significant difference in weight distribution index (WDI) in balance, but stability index (ST) showed a significant difference, and there was also a significant difference in correlation pre, post, post 5min rest, post 10 minutes rest (p<0.05). There was no significant difference in ankle muscle activity during walking in Tibialis anterior (TA), Medial gastrocnemius (GM), and Lateral gastrocnemius (GL) (p>0.05). Conclusion: The stability index (ST) increased significantly immediately after static stretching and decreased after 5 minutes. After static stretching, at least 5 minutes of rest are required to restore balance.

PURPOSE. This study assessed the physical and mechanical properties of interim crown materials fabricated using various digital techniques after accelerated aging. MATERIALS AND METHODS. Three groups of interim dental restorative materials (N = 20) were tested. The first group (CO) was fabricated using a conventional manual method. The second group (ML) was prepared from prefabricated resin blocks for the milling method and cut into specimen sizes using a cutting disc. The third group (3D) was additively manufactured using a digital light-processing (DLP) 3D printer. Aging acceleration treatments using toothbrushing and thermocycling simulators were applied to half of the specimens corresponding to three years of usage in the oral environment (N = 10). Surface roughness (Ra), Vickers microhardness, 3-point bending, sorption, and solubility tests were performed. A 2-way analysis of variance (ANOVA) and Fisher's multiple comparison test were used to compare the results among the groups. RESULTS. The mean surface roughness (Ra) of the resin after accelerated aging was significantly higher in the CO and ML groups than that before aging, but not in the 3D group. All groups showed reduced hardness after accelerated aging. The flexural strength values were highest in the 3D group, followed by the ML and CO groups after accelerated aging. Accelerated aging significantly reduced water sorption in the ML group. CONCLUSION. According to the tested material and 3D printer type, both 3D-printed and milled interim restoration resins showed higher flexural strength and modulus, and lower surface roughness than those prepared by the conventional method after accelerated aging.

Objective: To investigate airway volumes using cone-beam computed tomography (CBCT) by skeletal patterns, sex, and cervical vertebral maturation (CVM) stages in Korean adolescents. Methods: The sample consisted of pretreatment CBCT and cephalograms of 95 adolescents (aged 12-19) obtained out of 1,611 patients examined for orthodontic treatment from 2018 to 2020 in Kyungpook National University Dental Hospital. The samples were classified into two sex groups; three skeletal pattern groups, four chronological age groups and four CVM stages. Nasopharyngeal volumes (NPV), oropharyngeal volumes (OPV), total pharyngeal airway volume (TAV) and minimum cross-sectional area (MCA) measurements were taken from the CBCT. Multiple linear regression analyses to find out which one of the independent variables are good predictors for airway variables. Significant factors were analyzed by two-way multivariate analysis of variance (MANOVA) then multiple comparisons were analyzed using a t-test, and Fisher least significant difference. Results: Age, sex, CVM, and Sella-Nasion-B point have significant influence on airway variable. Males and females showed similar patterns of change in chronological age groups 1-3; however, males had larger NPV, OPV, and MCA at CVM in group 4. According to CVM stages, males had larger OPV, TAV, and MCA at CVM stage 6 (p-value: 0.019, 0.021, 0.015, respectively) and no sex differences at CVM stages 3, 4, and 5. Conclusions: Skeletal patterns have an effect on airway volume. Sex differences were found in CVM 6.

Background: There are various conservative treatment options for lateral epicondylitis (LE). The aim is to evaluate pain, daily functioning, and complications after ultrasound-standardized autologous blood injections in patients with LE. Methods: For this prospective cohort study, consecutive patients (>18 years) diagnosed with LE were included. Autologous blood was injected using a medical device containing an injection disposable with 12 small needles (Instant Tennis Elbow Cure [ITEC]) device. Patient-Rated Tennis Elbow Evaluation (PRTEE), subjective elbow score (SES), palpation and provocation pain, satisfaction, and complications of treatment were measured at baseline and two months after treatment. Paired t-tests and Fisher's exact tests were used for calculating the difference between pre- and post-treatment outcomes. Results: Fifty-five elbows were analyzed. Mean time between pre- and post-treatment was 11.1 weeks (standard deviation [SD], 8.9 weeks). The mean PRTEE score decreased from 68.2 (SD, 15.7) before surgery to 53.2 (SD, 25.9; p<0.001) after. The mean SES improved from 36.9 (SD, 20.8) to 51.7 (SD, 27.4; p<0.001). Despite this improvement, only 44.7% of patients showed relevant clinical improvement in PRTEE, and 37.3% showed significant clinical improvement based on SES. Four patients reported a complication and the injection disposable failed three times. Conclusions: Ultrasound-standardized autologous blood injection using the ITEC device is not an effective tool in reducing symptoms related to LE. This study showed that only half of all patients experienced a positive effect. In this heterogeneous cohort of patients, we showed no added value of ultrasound standardization.

Background: This study attempted to find out the degree of awareness of owners who have the most influence on companion animal's rehabilitation exercise, and the purpose of the treatment effect, and the expectations of rebilitation treatment. The purpose of this study is to find out about the awareness, comprehension, and expectations of caregiver for rehabilitation exercise in companion animal medical services, and to develop them into a field of animal medical services. Design: The tool used in this study used a questionnaire, and the composition consists of the subject's general characteristics, recognition of companion animal rehabilitation, comprehension and expectation. Methods: A questionnaire was given to 103 companion animal's owners, and all were collected and analyzed. Analysis of the frequency analysis method, Fisher's exact test were analyzed. Results: It was confirmed that the difference was significant in the question of whether the caregivers had heard companion animal rehabilitation (p<.05). When asked that rehabilitation is necessary to improve physical function, the difference was confirmed to be significant (p<.05). The significance was confirmed when asked if the caregiver was willing to participate in animal rehabilitation education (p<.05). When asked if caregiver was willing to recommend rehabilitation exercise for companion animal of other caregiver who need rehabilitation exercise, it was confirmed that the difference was significant (p<.05). Conclusion: There was significant difference between gender. This study confirmed that the definite concept caregivers' perception in animal rehabilitation was not established. Therefore, in order to improve perception of caregivers, interdisciplinary exchanges and publicity for animal rehabilitation are needed, and the development of training and education programs for rehabilitation experts was suggested.
