  • Background Lipedema is a chronic, incurable disorder characterized by painful fat accumulation in the extremities. While the application of liposuction in lipedema management has become increasingly popular, the safety and effectiveness of this approach remain contentious. Our systematic review and meta-analysis aimed to assess various liposuction modalities in lipedema management to verify their safety and efficacy. Methods In-line with the Preferred Reporting Items for Systematic Reviews and Metaanalyses guidelines, we performed a comprehensive literature review from inception untilMarch 2023 using the following electronic databases: CENTRAL,MEDLINE, Google Scholar, and EMBASE. Results From the 562 initially identified articles, 20 met our inclusion/exclusion criteria for evaluation. Our review encompassed 14 prospective cohort studies, 3 retrospective studies, 2 case series, and 1 cross-sectional study. Ameta-analysis of nine articles revealed a notable improvement in the quality of life, pain, pressure sensitivity, bruising, cosmetic impairment, heaviness, walking difficulty, and itching among lipedema patients who underwent liposuction. Although complications such as inflammation, thrombosis, seroma, hematoma, and lymphedema-related skin changes were reported, severe complications were rare. Crucially, no instances of shock, recurrence, or mortality were reported.

  • 인구통계학적 분석(Demographic Analysis: DA)은 센서스 및 동태자료의 포함오류에 대한 질적 평가를 위해 센서스 후 조사(Post Enumeration Survey: PES)와 함께 널리 이용되는 방법이다. 그러나 우리나라에서는 인구통계학적 분석이 시행된 적이 없으며, 해외 인구통계학 논문에서는 인구통계학적 분석을 통해 우리나라 사망자 등록의 후진성을 지적하고 있다. 본 논문에서는 다양한 인구통계학적 분석방법을 소개하고, 한국의 현실에 맞도록 변형시킨 방법을 제시한다. 또한 이를 이용하여 1985년부터 2010년까지의 센서스 및 사망자 자료를 분석한 결과, 우리나라의 사망자 자료는 해외 논문의 결과와 달리 완성도(completeness)가 높은 것으로 나타났다. 센서스의 연도별 연령별 누락률을 추정하여, 센서스의 비정상적인 코호트의 증가 현상, 성비, 그리고 연령비의 이상 현상에 대해 분석하였다.

  • Background and Objectives : In general, ambulatory 24-hour pH monitoring is considered the current gold standard for larynogopharyngeal reflux(LPR). There is no validated instrument whose purpose is to document the physical finding and severity of laryngopharyngeal reflux. The purposes of this study are to revaluate the validity and reliability of the reflux finding score(RFS) and to quantify laryngoscopic findings using reflux finding score. Material and Methods : Thirty-three LPR patients confirmed by dual-probe pH monitoring and thirty patients of control were selected. The RFS was documented for each patient with telescopic laryngoscopy before treatment. For test-retest intraobserver reliability assessment, a blinded laryngologists determined the RFS on two separate occasions. To evaluate interobserver reliability assessment, the RFS was determined by t재 different blinded laryngologists. Results : The mean age of the cohort with pH-documented LPR was 45.8 years and the mean RFS was 11.4. The mean age of cotrol subjects was 52 years and the mean RFS was 5.4. The mean RFS for laryngologist no. 1 was 10.8 at the initial screening and 10.9 at the repeat evaluation. The mean FRS for laryngologist no.2 was 11.1 at the intial test and 10.9 at the repeat evaluation. The correlation coefficient for interobserver variability was 0.93 and intraobserver variability was 0.94. Conclusion : The RFS demonstrates excellent inter-and introaobserver reproducibility and is helpful for quantifying laryngeal finding in LPR. We can be 95% certain that an individual with a RFS greater than 7 has LPR.

  • Objectives This study aimed to analyze the research trends in clinical studies on the traditional Korean medicine used for cancer treatment between 2011 and 2020. Methods We searched 7 Korean web databases (Research Information Sharing Service [RISS], Oriental Medicine Advanced Searching Integrated System [OASIS], Koreanstudies Information Service System [KISS], Korean Medical database [KMBASE], DBpia, Korea Institute of Science and Technology Information [KISTI], and KoreaMed) and classified collected papers dated between 2011 and 2020 by the year of publication, publication journal, study design, type of cancer affecting the patients, interventions used, evaluation system used, and combination with conventional medicine. Results A total of 167 papers were collected. More than 10 papers were published annually. The papers were mainly published in the Journal of Korean Traditional Oncology (28.7%). The predominant type of the study was case study (67.7%). The main type of cancer was breast cancer, affecting 262 patients. Most of the studies reported using multiple traditional Korean medicine treatments (55.1%). Eighty-nine studies reported using clinical laboratory tests for evaluation. Most of the patients took conventional medicine simultaneously (608 patients). Conclusions Research related to Korean medicine for cancer patients is at a rudimentary level. Therefore, for further clarity, high evidence-based researches, including randomized controlled trials and cohort studies, should be conducted.

  • Purpose: This study sought to examine the utilization of bone health evaluations in geriatric hip fracture patients and identify risk factors for the development of future fragility fractures. Materials and Methods: A consecutive series of patients ≥55 years who underwent surgical management of a hip fracture between September 2015 and July 2019 were identified. Chart review was performed to evaluate post-injury follow-up, performance of a bone health evaluation, and use of osteoporosis-related diagnostic and pharmacologic treatment. Results: A total of 832 patients were included. The mean age of the patients was 81.2±9.9 years. Approximately 21% of patients underwent a comprehensive bone health evaluation. Of this cohort, 64.7% were started on pharmacologic therapy, and 73 patients underwent bone mineral density testing. Following discharge from the hospital, 70.3% of the patients followed-up on an outpatient basis with 95.7% seeing orthopedic surgery for post-fracture care. Overall, 102 patients (12.3%) sustained additional fragility fractures within two years, and 31 of these patients (3.7%) sustained a second hip fracture. There was no difference in the rate of second hip fractures or other additional fragility fractures based on the use of osteoporosis medications. Conclusion: Management of osteoporosis in geriatric hip fracture patients could be improved. Outpatient follow-up post-hip fracture is almost 70%, yet a minority of patients were started on osteoporosis medications and many sustained additional fragility fractures. The findings of this study indicate that orthopedic surgeons have an opportunity to lead the charge in treatment of osteoporosis in the post-fracture setting.

  • 본 연구의 목적은 전국 대학 유아교육과의 효율성 변화를 분석하여 교원양성기관 역량진단의 효과성을 살펴보고, 효율적인 유아교육과와 비효율적인 유아교육과의 특성 및 효율성에 영향을 끼치는 변수들을 확인하여 정책적인 시사점을 제공하는 데에 있다. 연구목적을 위해 전국 대학 유아교육과 149개 데이터를 사용하여 자료포락분석을 실시, 교원양성기관 평가 완료 이전의 효율성 연구결과와 비교분석하였다. 불변규모수익기술과 가변규모수익기술을 가정한 산출지향 모형을 추정하여 CCR과 BCC모형으로 상대적 운영효율성 추정하였고, 투입요소로는 전임교원 1인당 학생 수, 학생 1인당 장학금, 전임교원 1인당 연구비, 학생 1인당 장서 수, 학생 1인당 교육비를 산출요소로는 전임교원 1인당 연구실적, 취업률을 사용하였다. 토빗모형을 통해 투입, 산출요소 및 외생변수(설립유형, 학교종류, 입학정원규모, 소재지) 중 효율성에 영향을 끼치는 요인들을 살펴보았다. 연구결과, 전국 대학 유아교육과는 효율적으로 운영되고 있으며 3주기 및 4주기 교원양성기관 평가 완료 전과 규모효율성과 운영효율성에 차이가 없었다. CCR에서 강효율 유아교육과는 학생 1인당 장학금, 장서 수, 교육비가 유의하게 낮음에도 불구, 유의하게 높은 전임교수 1인당 연구실적과 취업률을 보이나, BCC 아래 학생1인당 장서 수, 취업률 이외에는 통계적 유의성을 상실하며, 토빗모형 계수도 실제적인 영향을 논하기에는 미미하다. 전문대학과 입학정원규모 60명 이상, 광역권 유아교육과의 운영효율성이 높은 것으로 확인되었다. 본 연구결과는 교육의 질적 향상을 통한 효율성 증대를 목적으로 하는 평가정책에 시사점을 준다.

  • Objectives: Cardiovascular disease is one of the main causes of death and morbidity in Korea. In this study, the prevalence and incidence of developing hypertension in a male-workers' cohort were investigated during 3-years follow-up with a view to find the risk factors that affected the development of hypertension. Methods: Among the 5,374 people who participated in a routine health check up, 3,852 people with normal blood pressure and who had no history of hypertension were prospectively followed up for 3 years. The classification of hypertension was based on the JNC7 report (the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure). Life style factors and underlying diseases that were related to the risk factors of hypertension were collected by using a self-report questionnaires via the internet. Results: The prevalence of hypertension was 28.3% (1,520/5,374) at the first screening (2001). It was found that the incidence in 2004 of hypertension for the follow-up subjects (3,711) who had normal blood pressure in 2001 was 7.6 per 100 person-year. Multiple logistic regression analysis of the variables related to the risk factors of hypertension was carried out. The relative risks were 1.037 (95% CI=1.022-1.053) as the age increased 1 year and 1.039 (95% CI=1.023-1.055) as the body mass index increased $1kg/m^2$. The relative risk for the prehypertensive group was 2.501 (95% CI=1.986-3.149) compared to the normotensive group. These results showed that age, body mass index and the baseline blood pressure were significantly related to the incidence of hypertension. Conclusions: The incidence of hypertension was 7.6 per 100 person-year during follow-up. It was concluded that the risk factors for developing hypertension in the short-term were age, BMI, and prehypertension; Especially, this showed that it is necessary for prehypertensives to manage their body weight and blood pressure to prevent hypertension in middle-age by modifying their life style.

  • Objectives Cohort studies of associations between air pollution and health have used exposure prediction approaches to estimate individual-level concentrations. A common prediction method used in Korean cohort studies is ordinary kriging. In this study, performance of ordinary kriging models for long-term particulate matter less than or equal to $10{\mu}m$ in diameter ($PM_{10}$) concentrations in seven major Korean cities was investigated with a focus on spatial prediction ability. Methods We obtained hourly $PM_{10}$ data for 2010 at 226 urban-ambient monitoring sites in South Korea and computed annual average $PM_{10}$ concentrations at each site. Given the annual averages, we developed ordinary kriging prediction models for each of the seven major cities and for the entire country by using an exponential covariance reference model and a maximum likelihood estimation method. For model evaluation, cross-validation was performed and mean square error and R-squared ($R^2$) statistics were computed. Results Mean annual average $PM_{10}$ concentrations in the seven major cities ranged between 45.5 and $66.0{\mu}g/m^3$ (standard deviation=2.40 and $9.51{\mu}g/m^3$, respectively). Cross-validated $R^2$ values in Seoul and Busan were 0.31 and 0.23, respectively, whereas the other five cities had $R^2$ values of zero. The national model produced a higher cross-validated $R^2$ (0.36) than those for the city-specific models. Conclusions In general, the ordinary kriging models performed poorly for the seven major cities and the entire country of South Korea, but the model performance was better in the national model. To improve model performance, future studies should examine different prediction approaches that incorporate $PM_{10}$ source characteristics.
