Background: The objective of our study was to examine the clinical factors associated with bone microarchitecture in Koreans. To the best of our knowledge, only a few studies have investigated these factors. Methods: Data from patients who underwent a dual-energy X-ray absorptiometry scan at Seoul National University Hospital health promotion center between November 2014 and March 2015 were collected. The study population was divided into 2 groups, according to the patient's trabecular bone score (TBS) as follows: normal TBS ≥1.35 (n=700) and low TBS <1.35 (n=154). Intergroup comparison was carried out using the Student t-test and chi-square test. Logistic regression analysis, adjusted for age and body mass index (BMI), was applied to investigate the factors associated with TBS. Results: Data from 854 men and women were analyzed. Our results showed that TBS was inversely associated with age, BMI, waist circumference, serum phosphorus level (P), serum alkaline phosphatase level (ALP), serum C-terminal telopeptide (CTX), serum triglycerides (TG), serum C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and white blood count (WBC). Bone mineral density (BMD) was positively related to TBS. BMD, waist circumference, and serum ALP had an association with TBS in both men and women, after adjusting for age and BMI. Conclusion: Our findings suggest that obese patients (especially those with abdominal obesity) have worse bone microarchitecture. Serum P, ALP, CTX, TG, CRP, ESR, and WBC might have a negative association with TBS. Further studies are needed to clarify these findings.

연구목적 : 월경전기 증후군(Premenstrual Syndrome : PMS)은 가임기 여성의 약 80% 이상에서 발생하는 것으로 알려져 있다. 월경 주기와 일치하는 질환의 특성 상 여성 호르몬의 변화가 질환과 가장 밀접한 연관이 있는 것으로 알려져 있으나 아직까지 특징적인 생물학적 원인에 대한 일관된 보고는 되어 있지 않다. 이에 질환의 심리학적 원인에 대한 여러 가지 가설들도 제시되고 있는데 그 중에서도 심리적 외상 경험과의 연관성에 대한 연구들은 과거의 심리적 외상이 클수록 월경전기 증후군의 증상이 심해진다는 흥미로운 관점을 제시한다. 한편 과거의 심리적 외상은 해리 증상과도 연관이 있는 것으로 알려져 있는데 이러한 사실들로부터 월경전기 증후군과 해리증상의 연관성에 대한 가능성을 유추할 수 있다. 이에 본 연구에서는 월경전기 증후군의 정도와 해리증상 경험의 정도, 과거 학대 경험의 연관성을 알아보고자 하였다. 방법 : 본 연구는 서울 경기 경북에 근무하는 377명의 간호사들 중 설문과 기록을 충실하게 수행한 183명을 대상으로 하였다. 월경전기 증후군의 존재 여부와 증상의 정도는 Daily Record of Severity of Problems(DRSP), Shortened Premenstrual Assessment Form(SPAF)을 이용하여 측정하였다. 해리 증상의 정도는 Dissociation Experience Scale(DES-K)을 사용하였고 과거의 신체/언어적 학대 경험, 성적 학대 경험, 부모의 배우자 학대 경험은 각각 부모의 신체적 언어적 학대 방임 척도, 성적 학대 척도, 배우자 학대 척도를 이용하였다. 결과 : SPAF 점수를 기준으로 대상자들을 월경전기 증후군이 없는 군(No PMS), 경도에서 중등도의 증상을 경험하는 군(mild to moderate PMS), 중증의 증상을 경험하는 군(severe PMS)으로 나누었을 때 신체적 언어적 학대 방임 척도($x^2=14.397$, df=2, p=0.001), 성적 학대 척도($x^2=8.376$, df=2, p=0.015), 부모의 배우자 학대 척도($x^2=9.322$, df=2, p=0.009)에서 각 군 간에 유의한 차이를 보였다. 마찬가지로 DES 점수에서도 각 군 간에 유의한 차이가 있었다($x^2=14.966$, df=2, p=0.001). SPAF를 사용하여 측정한 월경전기 증후군의 증상 정도와 과거의 학대 경험 정도는 양의 상관관계를 보였으며 이는 해리 증상의 경험 정도에서도 마찬가지였다. 결론 : 상기 결과는 월경전기 증후군의 증상과 해리증상, 과거 외상경험이 연관이 있을 수 있음을 시사한다. Objectives : Premenstrual syndrome(PMS) is known to occur in more than 80% of reproductive women. Since PMS is closely related to changes in sex hormones, biological factors are suspected to be associated with the syndrome, but there have been no consistent reports regarding biological causes. In that sense, it is postulated that the occurrence of PMS is much dependent on the biological aspects, but that the severity or characteristics of the syndrome is more dependent on the psychological factors. Studies focusing on psychological factors are based on the theory that symptoms of PMS and previous psychologically traumatic events are closely related. If the theory is valid, it can be further postulated that symptom severity of PMS is associated with dissociative symptoms, since traumatic events are known to be related to dissociative symptoms. In this study, we tried to find out the association of PMS symptom severity with previous abuse history and dissociative symptoms. Methods : Subjects for the study were 377 nurses working in Seoul, Kyung-gi, and Kyung-book. 183 subjects who submitted valid data entered the study. The presence and the symptom severity of PMS were rated using Daily Records of Severity of Problems(DRSP) and Shortened Premenstrual Assessment Form(SPAF). Dissociative symptoms were evaluated with Dissociation Experience Scale Korean version(DES-K). Previous physical/verbal abuse, sexual abuse, and parental spouse abuse experience were rated with correspondent abuse scales. Results : Subjects were divided into 3 groups as No PMS group, mild to moderate PMS group, and severe PMS group according to SPAF total score. There was a statistically significant difference in DES-K total score among 3 groups($x^2=14.966$, df=2, p=0.001). Physical/verbal abuse scale($x^2=14.397$, df=2, p=0.001), sexual abuse scale($x^2=8.376$, df=2, p=0.015), and parental spouse abuse scale($x^2=9.322$, df=2, p=0.009) also revealed a significant difference among 3 groups. Symptom severity of PMS using SPAF total score showed a positive correlation both with degree of dissociative experience and previous abuse experience. There was a statistically significant difference in both dissociative experience and previous abuse experience among 3 groups. Conclusion : These results show that there can be a possible association among PMS symptoms, dissociative symptoms, and previous psychologically traumatic experience.

Osteoporosis is a medical condition of global concern, with increasing incidence in both sexes. Bone mineral density (BMD), a highly heritable trait, has been proven a useful diagnostic factor in predicting fracture. Because medical information is lacking about male osteoporotic genetics, we conducted a genome-wide association study of BMD in Korean men. With 1,176 participants, we analyzed 4,414,664 single nucleotide polymorphisms (SNPs) after genomic imputation, and identified five SNPs and three loci correlated with bone density and strength. Multivariate linear regression models were applied to adjust for age and body mass index interference. Rs17124500 (p = 6.42 × 10−7), rs34594869 (p = 6.53 × 10−7) and rs17124504 (p = 6.53 × 10−7) in 14q31.3 and rs140155614 (p = 8.64 × 10−7) in 15q25.1 were significantly associated with lumbar spine BMD (LS-BMD), while rs111822233 (p = 6.35 × 10−7) was linked with the femur total BMD (FT-BMD). Additionally, we analyzed the relationship between BMD and five genes previously identified in Korean men. Rs61382873 (p = 0.0009) in LRP5, rs9567003 (p = 0.0033) in TNFSF11 and rs9935828 (p = 0.0248) in FOXL1 were observed for LS-BMD. Furthermore, rs33997547 (p = 0.0057) in ZBTB and rs1664496 (p = 0.0012) in MEF2C were found to influence FT-BMD and rs61769193 (p = 0.0114) in ZBTB to influence femur neck BMD. We identified five SNPs and three genomic regions, associated with BMD. The significance of our results lies in the discovery of new loci, while also affirming a previously significant locus, as potential osteoporotic factors in the Korean male population.

Objectives : The aim of this study was to compare endogenous plasma lithium concentrations among schizophrenic patients classified by DSM-IV subtype and control groups and to investigate the correlation of endogenous plasma lithium concentration and psychotic symptoms in schizophrenia. Methods : Schizophrenic patients were selected among psychiatric inpatients without lithium medication and then classified by DSM-IV schizophrenia subtype, Schizophrenic patient groups were composed of 15 disorganized type, 15 paranoid type and 15 undilferentiated type schizophrenic patients. The control group was composed of 15 healthy subjects without any psychiatric disease,Endogenous plasma lithium concentrations were estimated by inductively coupled plasma atomic emission spectrometer. The psychotic symptoms in schizophrenic patients were classified as positive symptoms, negative symptoms and disorganized symptoms according to andreasen classificationl about SANS and SAPS items. Endogenous plasma lithium Con-centration among three subtypes of schizophrenia and control group was compared, and correlation between endogenous plasma lithium concentrations and psychotic symptoms was examined. Rcsults : 1) Schizoprenic patients showed higher endogenous plasma lithium concentration than control groups (p=0.033). Endogenous plasma lithium concentrations were significantly different among three subtypes of schizophrenia (p=0.001). Compared with the control group, disorganized type showed higher endogenous plasma lithium concentration, but paranoid type and undifferentiated type were not significantly different. 2) Disorganized symptoms correlated with endogenous plasma lithium concentration (r=0.416, P=0.004), but negative symptom and positive symptom did not significantly correlate with endogenous plasma lithium concentration (r=0.202, P=0.184. r= -0.216, P=0.155). Conclusion : These results suggested that schizophrenic patients with disorganized symptom show the differences in utilization or distribution of endogenous lithium.
