Background: Total ankle arthroplasty (TAA) is increasingly used as an alternative to ankle arthrodesis for patients with rheumatoid arthritis (RA), although its outcomes remain controversial. Using propensity score matching, this study compared clinical and radiographic outcomes of TAA for patients with RA and osteoarthritis (OA). Methods: Eighteen patients with RA were selected from 21 eligible cases and matched—using propensity score matching based on 8 baseline variables—to 36 patients with OA from a pool of 386. All patients underwent mobile-bearing TAA and were followed up for a minimum of 2 years. Clinical outcomes were assessed using the Ankle Osteoarthritis Scale, American Orthopaedic Foot and Ankle Society ankle–hindfoot score, Short Form-36 Physical Component Summary, and a visual analog scale for pain. Radiographic outcomes and postoperative complications were also evaluated. Results: At a mean follow-up of 7 years, both groups demonstrated improvement in all clinical outcome measures, with no significant differences between the RA and OA groups (p > 0.05). Radiographic outcomes, including postoperative tibiotalar angle, talar tilt angle, as well as the incidence values for periprosthetic osteolysis, implant subsidence, and aseptic loosening, were similar between groups. However, periprosthetic medial malleolar fractures occurred only in the RA group (3 cases, 16.7%; p = 0.033), and 2 cases of incision wound dehiscence were also observed in the RA group. No deep infections were reported in either group. Overall, reoperation rates did not differ significantly between groups. Conclusions Patients with RA who underwent TAA achieved clinical and radiographic outcomes comparable to those with OA.However, periprosthetic fractures and wound complications were more common in the RA group. Further studies with larger, matched cohorts and longer follow-up are needed to confirm these findings.

Purpose: The purpose of this study was to investigate factors related to homosexual adolescents in South Korea. Methods: Using statistics from the 12th (2016) Korea Youth Risk Behavior Web-based Survey, hierarchical logistic regression analysis was conducted. The study sample comprised 65,528 middle and high school students aged 12 to 18 years. Results: The significant predictors of homosexual intercourse were gender, attempted suicide, bullying at school experience, ever drinking, ever smoking, habitual or purposeful drug use, cohabitation with family, weekly allowance, and mother’s education levels. Conclusions The results suggest that gender-related interventions should be considered in school health education programs and that sexual health interventions for high-risk groups may be needed, given the factors predicting homosexual intercourse.

Background: Oral sulfate tablets (OSTs) are bowel preparation agents that combine oral sulfate solution and simethicone. This study compared the efficacy, tolerability, and safety of OST compared to 2 L-polyethylene glycol plus ascorbic acid (2 L-PEG/ASC). Methods: This prospective, randomized, controlled, single-blinded, multicenter, noninferiority trial enrolled 211 healthy adults who underwent colonoscopy between May 2020 and September 2022 at 13 university hospitals. The bowel cleansing rate was assessed using the Boston Bowel Preparation Scale (BBPS) and Harefield Cleansing Scale (HCS), and the preparation agents were administered in split regimens. Results: The total BBPS score (8.2 ± 1.5 vs. 7.8 ± 1.4, p = 0.040) and the high-quality bowel cleansing rates in the right colon (73.2% vs. 50.5), transverse colon (80.6% vs. 68.0%), and left colon (81.5% vs. 67.0%) on the BBPS were significantly higher in the OST group than in the 2 L-PEG/ASC group. However, the rates of successful cleansing according to BBPS (90.7% vs. 91.2%) and HCS (96.3% vs. 94.2%) did not significantly differ between the two groups.The taste, ease, and amount of consumption of the preparation agent; and willingness to repeat colonoscopy with the same agent (89.8% vs. 78.6%, P = 0.026) were significantly better in the OST group compared to the 2 L-PEG/ASC group. Adverse events and clinically significant laboratory changes were not significantly different between the two groups. Conclusion The OST was not inferior to 2 L-PEG/ASC in terms of bowel cleansing efficacy and showed better tolerability when used for bowel preparation for colonoscopy.

Purpose: Perspectives of radiation oncologists on oligometastatic disease was investigated using multi-layered survey. Materials and Methods: Online survey on the oligometastatic disease was distributed to the board-certified regular members of the Korean Society for Radiation Oncology. The questionnaire consisted of four domains: five questions on demographics; five on the definition of oligometastatic disease; four on the role of local therapy; and three on the oligometastatic disease classification, respectively. Results: A total of 135 radiation oncologists participated in the survey. The median length of practice after board certification was 22.5 years (range, 1 to 44 years), and the vast majority (94.1%) answered affirmatively to the clinical experience in oligometastatic disease management. Nearly two-thirds of the respondents considered the number of involved organs as an independent factor in defining oligometastasis. Most frequently perceived upper limit on the numerical definition of oligometastasis was 5 (64.2%), followed by 3 (26.0%), respectively. Peritoneal and brain metastasis were nominated as the sites to be excluded from oligometastastic disease by 56.3% and 12.6% of the participants, respectively. Vast majority (82.1%) agreed on the role of local treatment in the management of oligometastatic disease. Majority (72%) of the participants acknowledged the European Society for Radiotherapy and Oncology (ESTRO)–European Organisation for Research and Treatment of Cancer (EORTC) classification of oligometastatic disease, however, only 43.3% answered that they applied this classification in their clinical practice. Underlying reasons against the clinical use were ‘too complicated’ (66.0%), followed by ‘insufficient supporting evidence’ (30.0%), respectively. Conclusion While most radiation oncologists supported the role of local therapy in oligometastatic disease, there were several inconsistencies in defining and categorizing oligometastatic disease. Continued education and training on oligometastatic disease would be also required to build consensus among participating caregivers.
