연구배경: 트라우마가 초래한 정신건강 문제는 사건의 특성에 따라 다르게 나타날 수 있다. 특히 성적 외상사건 경험자는 다른 유형의 외상사건을 경험한 사람들보다 정신건강 결과가 부정적이라고 알려져 있을 뿐만 아니라, 디지털 성범죄 등 성적 사건에 노출될 수 있는 새로운 형태의 위협이 커지고 있다. 이 연구는 성적 트라우마 사건을 중심으로 트라우마 사건의 유형이 정신건강의 차이를 유발하는지 확인하고, 자살생각과 잠재적 post-traumatic stress disorder (PTSD) 위험수준에 영향을 미치는 요인을 확인하고자 하였다. 방법: 전국 20대부터 50대까지 성인을 대상으로 실시한 온라인 설문조사를 토대로, 경험한 트라우마 사건의 유형에 따라 분석대상자를 구분하였다(성적 트라우마 경험자, 비성적 트라우마 경험자). 성적 트라우마 사건 경험 여부를 제외하고 정신건강(자살생각, 잠재적 PTSD 위험수준)에 영향을 미칠 수 있는 인구사회학적 요인(성, 연령, 주관적 경제수준, 결혼상태)과 회복 보호요인(사회적 지지, 회복 가능성 인지, 아동기 보호경험)을 공변량으로 propensity score matching (PSM)을 실시하였다. 이후 정신건강에 영향을 미치는 요인을 확인하기 위해 이분형 로지스틱 회귀분석을 하였다. 결과: PSM 후에도 성적 트라우마 경험자는 비성적 트라우마 경험자보다 자살생각과 잠재적 PTSD 위험수준이 부정적이었다. 이분형 로지스틱 회귀분석 결과, 성적 트라우마 경험자는 비성적 트라우마 경험자보다 자살생각이 1.9배(odds ratio [OR], 1.911), 잠재적 PTSD 위험수준은 2.5배(OR, 2.472) 높았다. 또한 트라우마 회복 인식, 사회적 지지, 아동기 보호 경험과 같은 회복 보호요인이 부정적일수록 자살생각과 잠재적 PTSD 위험수준의 가능성이 높아졌다. 결론: 이 연구는 성적 트라우마 경험에 대한 이해와 지원의 중요성을 강조하고, 성적 트라우마 경험자의 자살생각과 잠재적 PTSD 위험을 완화하고 회복을 돕기 위해 회복 보호요인을 촉진하는 전략의 필요성을 시사한다.

Objective: The objective of this study was to estimate the genetic parameters for milk ${\beta}$-hydroxybutyrate (BHBA), acetone (Ac), fat protein ratio (FPR), and energy balance (EB) using milk test day records and investigate the effect of early lactation FPR and EB on milk ketone body concentrations. Methods: Total 262,940 test-day records collected from Korea Animal Improvement Association during the period of 2012 to 2016 were used in this study. BHBA and Ac concentrations in milk were measured by Fourier transform infrared spectroscopy (FTIR). FPR values were obtained using test day records of fat and protein percentage. EB was calculated using previously developed equation based on parity, lactation week, and milk composition data. Genetic parameters were estimated by restricted maximum likelihood procedure based on repeatability model using Wombat program. Results: Elevated milk BHBA and Ac concentrations were observed during the early lactation under the negative energy balance. Milk FPR tends to decrease with the decreasing ketone body concentrations. Heritability estimates for milk BHBA, Ac, EB, and FPR ranged from 0.09 to 0.14, 0.23 to 0.31, 0.19 to 0.52, and 0.16 to 0.42 respectively at parity 1, 2, 3, and 4. The overall heritability for BHBA, Ac, EB and FPR were 0.29, 0.32, 0.58, and 0.38 respectively. A common pattern was observed in heritability of EB and FPR along with parities. Conclusion: FPR and EB can be suggested as potential predictors for risk of hyperketonemia. The heritability estimates of milk BHBA, Ac, EB, and FPR indicate that the selective breeding may contribute to maintaining the milk ketone bodies at optimum level during early lactation.

Breast self-examination (BSE) is important for early diagnosis of breast cancer (BC). However, the majority of Turkish women do not perform regular BSE. We aimed to evaluate the effects of education level on the attitudes and behaviors of women towards BSE. A descriptive cross-sectional study was conducted on 413 women (20-59 years), divided into university graduates (Group I, n = 224) and high school or lower graduates (Group II, n = 189). They completed a 22-item scale assessing the knowledge level, attitudes and behaviors regarding BSE, and the Turkish version of the Champion's Revised Health Belief Model. A significantly higher number of women in Group II did not believe in early diagnosis of BC. A significantly higher number of Group I had conducted BSE at least once, and their BSE frequency was also significantly high. Moreover, a significantly lower number of Group I women considered themselves to not be at risk for BC and the scores for "perceived susceptibility" and "perceived barriers" were significantly higher. Logistic regression analysis identified the university graduate group to have a higher likelihood of performing BSE, by 1.8 times. Higher educational levels were positively associated with BSE performance. Overall, the results suggest that Turkish women, regardless of their education level, need better education on BSE. Consideration of the education level in women will help clinicians develop more effective educational programs, resulting in more regular practice and better use of BSE.

Purpose: To evaluate aggravating factors of intermittent locking among temporomandibular joint using magnetic resonance imaging (MRI) and diagnostic criteria for temporomandibular disorder (DC/TMD) diagnosis. Methods: A retrospective analysis was conducted of 35 patients with intermittent locking history but normal intra-articular findings between September 2012 and June 2015 in Kyung Hee University Dental Hospital. A standardized DC/TMD assessment was performed on subjects with MRI findings. Clinical findings were assessed on the basis of maximum mouth opening (active & passive), self-reported habits, patients' age, gender, systemic diseases at the initial visit. First, chi square test was used to examine differences with variables and then risk factors for intermittent locking were assessed using multivariate logistic regression. Results: Self-reported bruxism was strongly associated with intermittent locking history. Conclusions: The new DC/TMD protocol is intended for use within any clinical setting and supports the full range of diagnostic activities from screening to definitive evaluation and diagnosis. Self-reported sleep bruxism has been associated with a higher likelihood of intermittent locking. Comorbidity is therefore a factor that must be assessed. It is necessary to consider the amount of contact of the teeth and the duration.

Objectives: The aim of this study was to evaluate the relationship between depressive symptoms and oral health status in Korean middle-aged women. Methods: We analyzed data from the sixth Korea National Health and Nutrition Examination Survey (KNHANES VI). The final sample consisted of 2,691 adults aged 40-64 years. The Chi-squared test was used to assess the rate of depressive symptoms, oral health status, and relationship between oral health status and depressive symptoms. Moreover, logistic regression analysis was used to examine the association between depressive symptoms and oral health status. Data were analyzed using SPSS 20.0 program. Results: Overall, 15.1% of subjects experienced depressive symptoms. The rate of depressive symptoms in self-aware oral health, toothache, and mastication problem groups were 19.6%, 19.9%, and 25.3%, respectively. Compared to other groups, the likelihood (odds ratio) of having depressive symptoms was 1.47 (95% confidence interval [CI] : 1.16-1.88), 1.58 (95% CI: 1.22-2.04), and 1.73 (95% CI: 1.32-2.28) higher in self-aware bad oral health, toothache, and mastication problem groups, respectively. Conclusions: We found an association between depressive symptoms and oral health status. Thus, oral health status should be evaluated as a potential risk factor for depressive symptoms.

Objective : Intracranial ruptured vertebral artery dissecting aneurysms (VADAns) are associated with high morbidity and mortality when left untreated due to the high likelihood of rebleeding. The present study aimed to establish an endovascular therapeutic strategy that focuses specifically on the angioarchitecture of ruptured VADAns. Methods : Twenty-three patients with ruptured VADAn received endovascular treatment (EVT) over 7 years. The patient group included 14 women (60.9%) and 9 men (39.1%) between the ages of 39 and 72 years (mean age 54.2 years). Clinical data and radiologic findings were retrospectively analyzed. Results : Four patients had aneurysms on the dominant vertebral artery. Fourteen (61%) aneurysms were located distal to the posterior inferior cerebellar artery (PICA). Six (26%) patients had an extracranial origin of the PICA on the ruptured VA, and 2 patients (9%) had bilateral VADAns. Eighteen patients (78%) were treated with internal coil trapping. Two patients (9%) required an adjunctive bypass procedure. Seven patients (30%) required stent-supported endovascular procedures. Two patients experienced intra-procedural rupture during EVT, one of which was associated with a focal medullary infarction. Two patients (9%) exhibited recanalization of the VADAn during follow-up, which required additional coiling. No recurrent hemorrhage was observed during the follow-up period. Conclusion : EVT of ruptured VADAns based on angioarchitecture is a feasible and effective armamentarium to prevent fatal hemorrhage recurrence with an acceptable low risk of procedural complications. Clinical outcomes depend mainly on the pre-procedural clinical state of the patient. Radiologic follow-up is necessary to prevent hemorrhage recurrence after EVT.

Objectives: Refugees resettled in the US may be at risk for cardiovascular disease (CVD). However, little is known about CVD-related issues among Karen refugees who have migrated to the US from the Thai-Myanmar border. The purpose of this study was to examine CVD-related health beliefs and lifestyle issues among Karen refugees resettled in the US. Methods: Karen refugees resettled in the US from the Thai-Myanmar border (n=195) participated in a survey study on health beliefs related to CVD, salt intake, physical activity (PA), and smoking in the fall of 2016. Results: A high-salt diet, physical inactivity, and smoking were major lifestyle problems. Participants who adhered to a low-salt diet considered themselves to be susceptible to CVD. Most participants did not engage in regular PA. Regular PA was associated with less perceived susceptibility to CVD and greater perceived benefits of a healthy lifestyle for decreasing the likelihood of CVD. Conclusions: Each refugee population may require individualized strategies to promote PA and a healthy diet. Future studies should develop health education programs that are specifically designed for Karen refugees and evaluate such programs. In addition to health education programs on healthy lifestyle choices, tobacco cessation programs seem to be necessary for Karen refugees. At the same time, it is important to foster strategies to increase the utilization of preventive care among this population by promoting free or reduced-fee resources in the community to further promote their health.
