Objectives: The purpose of this study is to investigate the domestic study trends on habitual abortion treated with Korean medicine. Methods: We searched the studies on habitual abortion treated with Korean medicine via searching 5 Korean web databases. After searching studies, we analyzed 7 studies selected according to the selection and exclusion criteria. Results: Of the seven selected studies, five case-reporting studies and two retrospective chart analysis. The most applied intervention for habitual abortion was herbal medication. All patients took herbal medicine before pregnancy, and Seunggum-dan was widely used. 66.3% of pregnant patients after treatment took herbal medicine after pregnancy, and Anjeonyichen-tang was the most widely used. As a result of analyzing retrospective chart analysis studies, whether the patient's age was 35 years or older has a significant impact on the success rate of Korean medicine treatment. Conclusions: This study has provided a basis for using Korean medical intervention in the treatment of habitual abortion in clinical practice. In order to provide a more high-quality basis, reliable follow-up studies related to the effectiveness and stability of Korean medicine treatment for habitual abortion should be conducted in the future.

Cohorts are established and operated at medical schools as part of efforts to improve the quality of education. Chosun University College of Medicine clarified the purpose of establishing three cohorts in light of its core values and developed criteria and indicators for each purpose. An organization focusing on cohort construction and operation was established as the Cohort Committee under the Quality Improvement Committee, and guidelines were proposed. In addition, a database and system were developed to handle primary data efficiently, and tools for measuring psychological variables were created. The data collected by establishing a cohort, regions, and admission types of graduates were first analyzed for the following projects: (1) an analysis of the educational process and quality improvement to educate medical professionals who contribute to the community after graduation, and (2) an analysis of the educational process and quality improvement to secure excellence in the medical field (e.g., knowledge and clinical reasoning), using information on the academic achievements of students and graduates as primary data. Chosun University College of Medicine is conducting cohorts and longitudinal studies gradually, starting with a simple, practically feasible system to solve the difficulties faced in cohort establishment and operation. Medical educators hope that future data collection and analysis will improve the quality of medical school education and have practical implications.

Leadership development corresponds to the focus on the individual's success and competitiveness strategy. This is the optimal direction of the organization of attitude development because it covers two aspects of the student's personality development, professionally-oriented and self-centric. The aim of the study is to identify and compare the leadership level in second-and fourth-year students to see dynamics of development and implementation of the leadership phenomenon in the professional and personal making up of future specialists. Based on the theoretical analysis of the issue, the authors developed an objective and subjective diagnostic model for leadership skills. In this study, data of the objective diagnostic technique are the key. Subjective diagnostic technique for leadership skills provides insights for problem interpretation. At the level of the first group of respondents, the average Leadership Skills Level of the second-year students was quite low and was found within the medium level. The second group of respondents consisting of the fourth-year students showed a slight but effective improvement. The Leadership Skills of this group were found at a sufficient level. Positive dynamics was revealed for all criteria of leadership skills as a result of applying objective diagnostic methods: decreased percentage of students with negative and relatively low markers of Leadership Skills Level and corresponding increase in percentage of applicants with positive markers of Leadership Skills Level. Further research can be organized in the direction of identifying and developing successful universal and professionally-oriented tactics for leadership development in students as part of attitude development.

This case report presents the long-term radiographic outcomes of a novel approach for simultaneous lateral augmentation and implant surgery. A 60-year-old male patient who required tooth extraction of the maxillary central and lateral incisors due to trauma visited the clinic. After tooth extraction, severe horizontal and vertical deficiencies occurred owing to atrophy of the alveolar ridge, and a simultaneous guided bone regeneration (GBR) procedure was planned along with the installation of two implants. In the present case, a modification of the conventional 'sandwich technique' was used by placing the mixture of autogenous bone chips and xenografts at the outermost layer to maximize the osteogenic potential at the coronal part of augmentation while applying solely xenografts at the inner layer. To enhance volumetric stability, an autogenous block of periosteum harvested from the maxillary tuberosity was incorporated between the two layers. Cone-beam computed tomography was performed at baseline and 3 years after the surgery to compare radiographic outcomes. Dehiscence after fixture installation was successfully observed at the re-entry of the surgery site. Three years after the surgery, average horizontal bone gains of 6.11 mm and 4.12 mm were observed in the maxillary central and lateral incisor areas, respectively. Healthy peri-implant mucosa and well maintained marginal bone levels were observed 8 years after the surgery, meeting the criteria for implant success. The findings of this case suggest that a substantial amount of horizontal bone gain can be obtained with a layered approach using autogenous bone materials and xenografts, highlighting the advantages of incorporating autogenous blocks into the simultaneous GBR procedure.

Objective: To assess the technical performance of two-dimensional shear wave elastography (2D-SWE) for measuring liver stiffness. Materials and Methods: The Ovid-MEDLINE and EMBASE databases were searched for studies reporting the technical performance of 2D-SWE, including concerns with technical failures, unreliable measurements, interobserver reliability, and/or intraobserver reliability, published until June 30, 2018. The pooled proportion of technical failure and unreliable measurements was calculated using meta-analytic pooling via the random-effects model and inverse variance method for calculating weights. Subgroup analyses were performed to explore potential causes of heterogeneity. The pooled intraclass correlation coefficients (ICCs) for interobserver and intraobserver reliability were calculated using the Hedges-Olkin method with Fisher's Z transformation of the correlation coefficient. Results: The search yielded 34 articles. From 20 2D-SWE studies including 6196 patients, the pooled proportion of technical failure was 2.3% (95% confidence interval [CI], 1.3-3.9%). The pooled proportion of unreliable measurements from 20 studies including 6961 patients was 7.5% (95% CI, 4.7-11.7%). In the subgroup analyses, studies conducting more than three measurements showed fewer unreliable measurements than did those with three measurements or less, but no intergroup difference was found in technical failure. The pooled ICCs for interobserver reliability (from 10 studies including 517 patients) and intraobserver reliability (from 7 studies including 679 patients) were 0.87 (95% CI, 0.82-0.90) and 0.93 (95% CI, 0.89-0.95), respectively, suggesting good to excellent reliability. Conclusion: 2D-SWE shows good technical performance for assessing liver stiffness, with high technical success and reliability. Future studies should establish the quality criteria and optimal number of measurements.

The purpose of this meta-analysis is to compare the postoperative outcomes and complications of labral repair with those of labral reconstruction. An electronic search strategy was conducted from 1986 until August 2023 using the following databases: PubMed, Cochrane, and Google Scholar (pages 1-20). The primary objectives included the postoperative clinical outcomes determined by the number of patients who reached minimal clinical important difference (MCID) on the visual analog scale (VAS), modified Harris hip score (mHHS), Hip Outcome Score-Sports Subscale (HOS-SS), Hip Outcome Score-Activities of Daily Life (HOS-ADL), and International Hip Outcome Tool-12 (iHOT-12). In addition, analysis of the rate of revision arthroscopy, the rate of conversion to total hip arthroplasty (THA), the postoperative VAS, mHHS, HOS-SS, HOS-ADL, iHOT-12, nonarthritic hip score (NAHS), patient satisfaction, lower extremity function scale (LEFS), and the SF-12 (12-item shortform) was also performed. Any differences arising between the investigators were resolved by discussion. Seventeen studies were relevant to the inclusion criteria and were included in this meta-analysis. A higher rate of patients who reached MCID in the mHHS (P=0.02) as well as a higher rate of revision arthroscopy was observed for labral repair (P=0.03). The remaining studied outcomes were comparable. Despite the greater predictability of success in the reconstruction group, conduct of additional studies will be required for evaluation of the benefits of such findings. In addition, labral reconstruction is more technically demanding than a labral repair.
