BACKGROUND: Venous thromboembolism (VTE) is a common and life-threating condition in cancer patients. Low molecular weight heparins (LMWH), such as dalteparin, are recommended in the treatment of VTE. Also, rivaroxaban, an orally administered direct factor Xa inhibitor, was approved for the treatment of VTE. It showed similar efficacy to standard therapy (LMWH or warfarin) and was associated with significantly lower rates of major bleedings. However, in the real world, bleeding has been reported to occur frequently in cancer patient receiving rivaroxaban. The goal of this research was to analyze bleeding risks between rivaroxaban and dalteparin for treatment of VTE in cancer patients. METHODS: Medical records of oncology patients who were treated with rivaroxaban or dalteparin for VTE from July 2012 to June 2014 were retrospectively reviewed. Data collected were as follows: age, sex, weight, height, cancer types and stages, ECOG (eastern cooperative oncology group) PS (performance score), VTE types, concurrently used medications, study drug information (dose and duration of therapy), INR (international normalized ratio), PT (prothrombin time), and platelet counts. Bleeding was classified into major bleedings, clinically relevant non-major bleedings, and minor bleedings. RESULTS: A total of 399 patients were included in the study. Of these patients, 246 were treated with rivaroxaban and 153 with dalteparin. Bleeding rates were significantly higher in the rivaroxaban group than in the dalteparin group (adjusted odds ratio (AOR) 2.09, 95% CI 1.22-3.60) after adjusting for confounders. In addition, rivaroxaban remained independently associated with 1.78-fold (95% CI 1.14-2.76) shorter time to bleeding compared to dalteparin after adjusting other factors known to be associated with poor outcomes. CONCLUSION: This study suggested that rivaroxaban was associated with an increased risk of bleedings in cancer patients.

Behcet's disease is a multisystem inflammatory disorder with a chronic relapsing course. It is considered a nonspecific systemic vasculitis involving both, venous and arterial circulation. Although lower extremity vein thrombosis (LEVT) is one of the most common manifestations of vascular involvement, a few cases are reported in the literature and to our knowledge, and only 2 cases were reported in Korea. We report a case of a 40-year-old Korean man with localized erythematous macules and patches on both lower extremities with a marked painful swelling on the right leg. The patient reported a history of similar lesions 10 years prior to presentation and also a history of recurrent aphthous oral ulcerations. Based on phlebographic findings of old LEVT in the right femoral vein, the patient was diagnosed with Behcet's disease associated with LEVT.

Tofacitinib, a Janus kinase inhibitor, was developed for the treatment of rheumatoid arthritis. Recently, it has been associated with an increased change in arthritis development in patients with diabetes. Herein, we evaluated the pharmacokinetics of tofacitinib after intravenous (10 mg/kg) and oral (20 mg/kg) administration to rats with streptozotocin-induced diabetes mellitus and control rats. Following intravenous administration of tofacitinib to rats with streptozotocin-induced diabetes mellitus, area under the plasma concentration-time curve from time zero to infinity of tofacitinib was significantly smaller (33.6%) than that of control rats. This might be due to the faster hepatic intrinsic clearance (112%) caused by an increase in the hepatic cytochrome P450 (CYP) 3A1(23) and the faster hepatic blood flow rate in rats with streptozotocin-induced diabetes mellitus than in control rats. Following oral administration, area under the plasma concentration-time curve from time zero to infinity of tofacitinib was also significantly smaller (55.5%) in rats with streptozotocin-induced diabetes mellitus than that in control rats. This might be due to decreased absorption caused by the higher expression of P-glycoprotein and the faster intestinal metabolism caused by the higher expression of intestinal CYP3A1(23), which resulted in the decreased bioavailability of tofacitinib (33.0%) in rats with streptozotocin-induced diabetes mellitus. In summary, our findings indicate that diabetes mellitus affects the absorption and metabolism of tofacitinib, causing faster metabolism and decreased intestinal absorption in rats with streptozotocin-induced diabetes mellitus.

Background: Daytime sleepiness, a common phenomenon among adolescents focused on academics, has negative effects on aspects such as growth and overall learning. However, research on various drugs and diseases affecting daytime sleepiness is lacking in the reality. Therefore, this study aims to investigate the factors influencing daytime sleepiness in adolescents with daytime sleepiness. Methods: This study was conducted through a survey of 2,432 middle and high school students, aged 14 to 19. The questionnaire consisted of information on socio-demographic characteristics, overall health status, and sleep patterns. The Pediatric Daytime Sleepiness Scale (PDSS), translated into Korean, was used to assess daytime sleepiness. Daytime sleepiness was measured bycalculating the total score for each item of the PDSS, and divided into two groups based on the cutoff value of 19, which was theupper quartile. Results: We analyzed a total of 1,770 students including 799 boys and 971 girls. Students with a PDSS score of 19or higher made up 33.3% of boys and 66.7% of girls. In multivariate analyses, females, smoking, poor self-reported health level, sleep after 12 am, not feeling refreshed in the morning, headache, muscle pain, and scoliosis increased the risk of daytime sleepinesssignificantly. The AUROC of PDSS, including significant factors in multivariate analyses, was 0.751 (95% CI 0.725~0.776). Conclusions Daytime sleepiness in adolescents affects growth, academic performance, and emotional stability. Therefore, it is important to manage medications, diseases, and other factors that affect daytime sleepiness on a social level.

PURPOSE: This study aimed to investigate the safe medication utilization and the education demands during pregnancy and it further reported the development of educational materials for pregnant women. METHODS: A survey was conducted in two tertiary care university hospitals and one community hospital specialized in obstetrics and gynecology from July 2 to 29 2014. The survey questionnaires included the usage of medications and the unmet needs on medication use during pregnancy. Ad ditionally, pregnant women's requests regarding to medication use were collected through group interviewing of community pharmacists. Based on these results, educational materials were de veloped and implemented. After implementing the education sessions, the satisfaction was evaluated. RESULTS: A total of 152 pregnant women answered completely the questionnaire. Among them, 130 participants (42.8%) were given the medication information from their physicians. Exposure to a teratogenic drug during pregnancy was a major concern for most pregnant women (79.6%). The majority (90.1%) of subjects reported a necessity of medication-related education during their pregnancy. The interview with 48 pharmacists indicated that the most commonly used OTC drugs in pregnancy were vitamins (25.2%), iron supplements (23.7%), and the most frequently used prescription drugs were antiinflammatory-analgesics (25.3%), followed by antibiotics (20.9 %). Based on the results, booklets of drug therapy during pregnancy, leaflet of pregnancy category index were made. Also, on-line flash and presentation materials for instructors were prepared. Through the trial education with the developed materials, it was confirmed that the contents of education materials were well understood and satisfied by the pregnant women. CONCLUSIONS: This study showed the need of the medication-related education for the pregnant women. The developed education materials would be helpful sources to provide accurate and reliable medication-related information to health professionals and pregnant women.

Bone age (BA) advancement in prepubertal children may be associated with earlier onset of puberty and obesity. This study aimed to define the effects of adrenal androgen levels on the advancement of BA in prepubertal children, independent of obesity. During July and August 2011, we examined BA in 200 prepubertal children aged 7–9 years who were part of the Ewha Birth & Growth Cohort Study. BA was assessed by the Greulich-Pyle method. An index of BA advancement was calculated as the ratio of BA to chronological age (CA) (BA/CA), and this ratio was classified into 3 tertiles. We analyzed the relationship between BA advancement and anthropometric characteristics and adrenal hormone levels. The number of overweight children increased from the first group to the third group (P(Trend) = 0.03). The levels of adrenal androgens showed a significant positive correlation with the tertile groups after adjusting for age and sex (testosterone: r = 0.26, P < 0.001; dehydroepiandrosterone: r = 0.21, P < 0.001; androstenedione: r = 0.20, P < 0.001). Further, after controlling for body mass index (BMI), sex, and age, the BA/CA was found to be positively correlated with androstenedione (β = 0.04, R² = 3.7%) and testosterone levels (β = 0.05, R² = 4.7%). Based on our results, it is suggested that adrenal androgen levels are associated with BA advancement independent of BMI.
