Background: There have been no large-scale population-based studies to estimate the subsequent risk of primary liver cancer (PLC) among patients with pyogenic liver abscess (PLA). This study aimed to provide relevant data. Materials and Methods: The Taiwan Longitudinal Health Insurance Database for the years 2000 and 2005 was used. The PLA group were adult inpatients who were newly diagnosed with PLA from 2000 to 2008. The control group was randomly selected and matched with the PLA group in terms of age, sex, and date in which medical treatment was sought other than for PLA. Results: There were 1,987 patients each in the PLA and control groups. In total, 56 had PLC, 48 (2.4%, 601.5 per 100,000 person-years) from the PLA group, and 8 from the control group. After adjusting for potential covariates, the hazard ratio of PLC for the PLA group was 3.4 times that of the control group (95% confidence interval = 1.6-7.3, p <0.001). The PLC risk for the PLA group was significantly higher within the first year after PLA diagnosis (hazard ratio: 35.4) as compared with the control group and became insignificant (hazard ratio: 2.0, 95% confidence interval = 0.8-4.9) more than one year after PLA diagnosis. Conclusions: Patients with PLA have a higher rate of PLC than matched controls, especially within the first year after the diagnosis of PLA, suggesting PLA is a warning sign for PLC.

이 연구는 경기도 한 농촌지역 주민 1,663명을 대상으로 10년 간의 6차례 조사를 시행하여 체질량지수와 과체중의 변화를 파악하였다. 그 결과 체질량지수는 성별과 연령을 보정한 후에도 조사 시기에 따라 증가하는 경향을 보였다. 과체중 이상의 유병률도 각 연령군 내에서 시기별로 증가하는 경향을 나타내었고, 이는 여자에게서 뚜렷하였다. 연령별 층화한 과체중의 유병률은 남자에게서 40대와 50대에서 시간의 경과에 따른 증가가 유의하게 나타났으며, 여자에게서는 40대, 50대, 60대에서 유의한 증가를 보였다. 남자와 여자 모두 1990년에서 1999년까지의 증가폭은 40대에서 가장 높았으며, 남자의 전체 증가폭이 여자의 경우 보다 높았으나 여자의 과체중 유병률이 더욱 높았다. 전체 인구의 1990년에서 1999년까지의 과체중 유병률은 통계적으로 유의하지는 않았으나 34.1%에서 63.9%로 29.8%의 증가폭을 보였으며 시간의 증가에 따라 유의한 증가의 경향을 보였다. 농촌 지역 남자의 체질량지수와 과체중의 유병률은 다른 집단과 비슷한 양상을 띄었으나 여자에게서 유병률이 높은 것을 알 수 있었다. 그러므로 이에 대한 원인을 규명하는 연구가 시행되어야 할 것이다.

Background: Woman kidney donors face obstetric complication risks after kidney donation, such as gestational hypertension and preeclampsia. Studies on childbirth-related complications among Asian women donors are scarce. Methods: This retrospective cohort study included woman donors aged 45 years or younger at the time of kidney donation in a single tertiary hospital between 1985 and 2014. Pregnancy associated complications were investigated using medical records and telephone questionnaires for 426 pregnancies among 225 donors. Matched non-donor controls were selected by propensity score and the maternal and fetal outcomes were compared with those of donors. Primary outcomes were differences in maternal complications, and secondary outcomes were fetal outcomes in pregnancies of the donor and control groups. Results: A total of 56 cases had post-donation pregnancies. The post-donation pregnancies group was younger at the time of donation and older at the time of delivery than the pre-donation pregnancies group, and there were no differences in primary outcomes between the groups except the proportion receiving cesarean section. Comparison of the complication risk between post-donation pregnancies and non-donor matched controls showed no significant differences in gestational hypertension, preeclampsia, or composite outcomes after propensity score matching including age at delivery, era at pregnancy, systolic blood pressure, body weight, and estimated glomerular filtration ratio (odds ratio, 0.63; 95% confidence interval, 0.19-2.14; P = 0.724). Conclusion: This study revealed that maternal and fetal outcomes between woman kidney donors and non-donor matched controls were comparable. Studies with general population pregnancy controls are warranted to compare pregnancy outcomes for donors.

Study Design: Retrospective review. Purpose: To identify the trends in stimulator use, pair those trends with various grafting materials, and determine the influence of stimulators on the risk of revision surgery. Overview of Literature: A large number of studies has reported beneficial effects of electromagnetic energy in healing long bone fractures. However, there are few clinical studies regarding the use of electrical stimulators in spinal fusion. Methods: We used insurance billing codes to identify patients with lumbar disc degeneration who underwent anterior lumbar interbody fusion (ALIF). Comparisons between patients who did and did not receive electrical stimulators following surgery were performed using logistic regression analysis, chi-square test, and odds ratio (OR) analysis. Results: Approximately 19% of the patients (495/2,613) received external stimulators following ALIF surgery. There was a slight increase in stimulator use from 2008 to 2014 (multi-level $R^2=0.08$, single-level $R^2=0.05$). Patients who underwent multi-level procedures were more likely to receive stimulators than patients who underwent single-level procedures (p<0.05; OR, 3.72; 95% confidence interval, 3.02-4.57). Grafting options associated with most frequent stimulator use were bone marrow aspirates (BMA) plus autograft or allograft for single-level and allograft alone for multi-level procedures. In both cohorts, patients treated with bone morphogenetic proteins were least likely to receive electrical stimulators (p<0.05). Patients who received stimulation generally had higher reimbursements. Concurrent posterior lumbar fusion (PLF) (ALIF+PLF) increased the likelihood of receiving stimulators (p<0.05). Patients who received electrical stimulators had similar revision rates as those who did not receive stimulation (p>0.05), except those in the multilevel ALIF+PLF cohort, wherein the patients who underwent stimulation had higher rates of revision surgery. Conclusions: Concurrent PLF or multi-level procedures increased patients' likelihood of receiving stimulators, however, the presence of comorbidities did not. Patients who received BMA plus autograft or allograft were more likely to receive stimulation. Patients with and without bone stimulators had similar rates of revision surgery.

Objectives: To investigate efficacy of Korean medicine for patients with Parkinson's Disease (PD) with pain. Methods: We performed a retrospective review of the medical records for patients diagnosed with PD between 2012 and 2019 at Gangdong Kyung Hee University Korean Medicine Hospital in South Korea. Results: Twenty-two patients with King's Parkinson's Disease Pain Scale(KPPS) scores at least twice were analyzed for evaluating the efficacy of Korean medicine for pain treatment in PD. The mean total scores before and after Korean medicine treatment were 15.23±1 .01 and 9.2±8.7, respectively, and the mean difference between the before/after total scores was 6.0±5.8 (P<0.001). Specifically, the score of radicular pain was significantly decreased (P=0.048). Conclusions: These findings suggest that Korean medicine could be beneficial for reducing pain associated with PD. Clinical efficacy should be confirmed by further studies, such as large-sample cohort studies and randomized controlled trials to clarify the pathological pain relief mechanism and the analgesic effect of Korean medicine.

PURPOSE: This review sought to confirm the correlation between dual-task gait and cognitive function in cognitively impaired and healthy older adults. METHOD: We used four databases (DBs), Pubmed, Cochrane library, Kmbase, and Koreamed. Searches were carried out according to the PICOS method, P (participants) were the elderly (above 65 years) with cognitive decline, I (intervention) was walking with dual tasks, C (control group) comprised the elderly without cognitive decline, O (outcome) was the correlation between gait and cognitive function and S (study) was the cross-sectional study. For the methodological quality assessment of each study, we used the Quality Assessment Tool for Observation Cohort and Cross-Sectional Studies provided by the National Institutes of Health (NIH). RESULTS: A total of 10 articles were included in this systematic review. For the components of gait, we used pace, rhythm, and variability and we observed that mild cognitive impairment mostly causes low gait performance while performing dual tasks. Among the 10 articles, 9 articles studied pace, of which 7 showed significant results. However, 2 were not significant. Also, 1 article that studied rhythm and 3 articles that studied variability showed significant results. The methodological quality of the 10 studies was fair. CONCLUSION: Gait pace was found to have a high correlation between memory, which is a cognitive ability, and overall cognitive function. It was observed that older adults with mild cognitive impairment have reduced gait pace in single-task walking, and further decrease in dual-task gait pace shows the correlation between memory and gait pace during walking.

Objectives: Tic disorders are highly heritable; however, growing evidence suggests that environmental factors play a significant role in their pathogenesis. Studies on these factors have been inconsistent, with conflicting results. Therefore, this study aimed to examine the associations of pre- and perinatal exposure to Tourette syndrome (TS) or chronic tic disorders (CTD) in Korean school-aged children. Methods: This case-control study used data from a large prospective cohort study. The primary outcome was TS/CTD diagnosis according to the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) criteria and Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version-Korean Version. Demographic, pre-, and perinatal information was obtained from the maternal questionnaires. Data between the TS/CTD and control groups were compared using the chi-squared or Student's t-test, as appropriate. Two-step logistic regression analyses were used to test the association between TS/CTD and pre- and perinatal risk factors. Results: We included of 223 children (78 with TS/CTD and 145 controls). Significant differences in the demographic data between the two groups were observed. The male sex ratio, mean parental age, parental final education level, and family history of tics were included as confounders. In the final adjusted multivariable model, TS/CTD was significantly associated with antiemetic exposure during pregnancy (odds ratio [OR]=16.61, 95% confidence interval [CI] 1.49-185.22, p=0.02) and medically assisted reproduction (OR=7.89, 95% CI 2.28-27.28, p=0.01). Conclusion: Antiemetic exposure and medically assisted reproduction are significantly associated with the risk of TS/CTD. These results should be replicated in future prospective and gene-by-environment studies.

본 연구는 노년기 인지기능과 일상생활기능장애 변화양상을 분석하고, 이에 대한 인구사회학적 요인의 영향력을 검증하는 것을 목적으로 하였다. 특히 인지손상정도에 따라 변화양상과 인구사회학적 요인의 영향력이 다를 것이라는 가정 하에, 정상인지를 가진 지역사회 거주노인에서 이후 6년여의 추적조사 기간 동안 치매가 발생한 집단(치매발생집단)과 정상인지를 유지하고 있는 집단(정상유지집단)에 따른 차이를 분석하는 것에 초점을 두었다. 분석 자료는 경기도 연천지역에 거주하는 65세 이상 노인 966명을 대상으로 3년여 간격으로 3회 추적 조사된 역학조사 자료를 사용하였다. 자료 분석은 구조방정식모형을 활용한 잠재성장모형(Latent growth model)과 다중집단분석(Multi-group analysis)을 실시하였으며, 통계프로그램은 AMOS 18.0을 사용하였다. 연구 결과, 치매발생집단은 치매로 진단되기 수년 전부터 정상유지집단에 비해 인지기능이 유의하게 낮을 뿐 아니라 이후 인지저하가 약 3.5배가량 빠르게 진행되었다. 일상생활기능장애 궤적의 경우 초기에는 집단 간 유의한 차이가 없다가, 이후 치매발생집단의 일상생활기능장애가 정상유지집단에 비해 약 3배가량 더 급속히 악화되는 것으로 나타났다. 인지기능과 일상생활기능장애에 대한 인구사회학적 요인의 영향력을 살펴본 결과, 인지저하는 여성에서 더 급격한 반면, 일상생활기능저하는 남성에서 더 현저하게 나타났으며, 생애초기에 결정되는 학력이 생애후기의 인지기능에 강력한 영향력을 갖는 것으로 나타났다. 이러한 연구결과에 근거하여 노년기 인지기능과 일상생활기능장애에 대한 개입에서 주목해야 할 고위험군과 그에 대한 실천적 함의를 논의하였다.
