  • Background: Diagnostic difficulties in hematological malignancies may lead to unacceptably prolonged help-seeking to diagnostic interval as well as increased complications and poor outcomes. Proactive consultation by a clinical pathologist (PCCP) may help clinical diagnosis and therapeutic strategy. Hence, the aim of this investigation was to evaluate the effect of PCCP on the help-seeking to diagnostic interval in hematological cancer cases. Materials and Methods: From January to November, 2015, abnormal results of hematological laboratory testing with added laboratory comment were selectively screened out, and patients with such abnormalities in hematological laboratory testing and accompanied laboratory comment with PCCP were enrolled. Results: A total of 125 aberrant results of hematological laboratory testing were given with accompanied laboratory comments with PCCP and 40.8% (n=51) of these patient-oriented comments had an effect on clinical diagnosis and therapeutic strategy. Twelve of the subjects belonged to newly diagnosed hematological malignancies with the assistance of PCCP, and the help-seeking to diagnostic interval was also shortened from 42 days to 26 days in chronic lymphoid leukemia (CLL), from 83 days to 11 days in multiple myeloma (MM), and from 128 days to 15 days in myelodysplastic syndrome/myeloproliferative neoplasm (MDS/MPN). During the monitoring interval, neither complication events nor deaths were reported in the study group. Conclusions: It was seemingly that PCCP prevented diagnostic delay in hematological malignancies via shortening the help-seeking to diagnostic interval, particularly in CLL, MM and MDS/MPN cases. PCCP can be considered to play an essential role in prompt establishment of diagnosis in hematological malignancies for those who newly present.

  • Background: Recently clinical trials have expanded extensively in Korea; thus, ensuring the rights of subjects participating in clinical trials is imperative. Accordingly, national regulations on subject recruitment advertisement were enforced from October 25, 2018. In this study, the effect of this regulation was evaluated by analyzing the difference in the provision of information before and after enforcement of the regulation. Methods: Recruitment advertisements for clinical trial subjects 3 years before and after enforcement of the regulation were collated by the significance sampling approach. Print-based (newspapers, buses, and subways) and web-based (clinical trial center websites and online platforms) materials for recruitment in clinical trials of phase 1 to 4 for investigational drugs, medical devices, and oriental medicine were considered. Chi-square tests were conducted for inter-group comparisons. SPSS version 26 was employed for statistical analyses. Results: A total of 137 advertisements were collected comprising 60 pre- and 77 post-regulation enforcement. The overall rate of delivery of critical information in advertisements increased significantly from 47.5% before regulation to 93.2% after regulation enforcement. Particularly, details on expected adverse events augmented significantly (p<0.001). Benefits from participation in clinical trial reduced significantly from 88.3% to 70.1% (p<0.05). As the information provision amplified, the inclusion of professional terms increased. Conclusions: Enforcement of regulations has led to a surge in the amount of information and challenging terms contained in advertisements for recruiting subjects. Therefore, additional efforts are required by subjects to completely understand the information provided in the advertisements.

  • Purpose: The purpose of this study was to test the effects of clinical practice in school on clinical competence in nurse. Method: This study used a quasi experimental post-test design. Data were collected after post-test from April 1, 2005 to May 30, 2005 and from 73 clinical nurses(53 experimental group, 20 control group) who work for 4 General hospitals. Data were analyzed using SPSSWIN 11.5 with $X^2$-test, t-test, Mann-Whitney U-test, and stepwise multiple regression. The experimental group participated in treatment : 4-week consecutive clinical nursing education with preceptor in schooling, and the control group participated in treatment : traditional clinical nursing education with preceptor in schooling. Results: Clinical competence were significantly different between experimental and control groups(t=3.221, p=.002). Clinical competence in nurse is effected by satisfaction of clinical practice in schooling in experimental group(F=14.781, p=.000). Conclusion: 4-week consecutive clinical nursing education with preceptor has an effect on clinical competence in nurse. Therefore we should spread and reinforce the 4-week consecutive clinical nursing education program for improving clinical competence of nurse.

  • Therapeutic effect of Yinyang Balancing Appliance of functional cerebrospinal therapy (FCST) for meridian and neurologic yinyang balance was observed in tic disorder patients. Seventy tic disorder cases were managed with the Yinyang Balancing Appliance on temporomandibular joint (TMJ), combined with acupuncture. Clinical outcome measurement was based on subjective measures and overall clinical impressions. Patients showed a trend toward improvement by clinical observations. In some cases, such changes were visible even after the initial treatment, and this effect was observed to be maintained over the follow-up period. Further clinical and biological research on tic disorder is expected with respect to the FCST.

  • This tutorial reviews the principles of dose individualisation with an emphasis on target concentration intervention (TCI). Once a target effect is chosen then pharmacodynamics can predict the target concentration and pharmacokinetics can predict the target dose to achieve the required response. Dose individualisation can be considered at three levels: population, group and individual. Population dosing, also known as fixed dosing or "one size fits all" is often used but is poor clinical pharmacology; group dosing uses patient features such as weight, organ function and comedication to adjust the dose for a typical patient; individual dosing uses observations of patient response to inform about pharmacokinetic and pharmacodynamics in the individual and use these individual differences to individualise dose.

  • To evaluate the physioactivity of Salicornia herbacea L. (SH), which are obtained from Sunchon bay as wild plants, an SH extract was prepared by freeze drying to obtain SH, and by cold drying to obtain SH. For the evaluation of their bioactivities, cell viability and antioxidative effect were measured. The XTT assay was adopted to measure cell viability after C6 glioma cells were treated with various concentrations of reactive oxygen species (ROS) and hydrogen peroxide ($H_2O_2$) for 8 hours. The DPPH-radical scavenging activity was also measured for the antioxidative effect. In this study, the $XTT_{50}$ value of $H_2O_2$ was determined at $30{\mu}M$ which was highly toxic based on the cytotoxic criteria by Borenfreund and Puerner. The protective effect of SH extract significantly increased cell viability compared with $H_2O_2$-treated group. Its antioxidative effect showed a significant DPPH-radical scavenging activity at concentrations of $1-100{\mu}g/mL$, while SH extract showed highly a DPPH-radical scavenging activity at only $100{\mu}g/mL$. From these results, $H_2O_2$ was highly toxic in cultured C6 glioma cells, and SH extract was effective in the prevention of cell damage by its antioxidative effect.
