Objectives: This study aimed to develop nutrition education program for consumers to reduce sodium intake based on social cognitive theory (SCT). Methods: The main factors of SCT related to low sodium diet were investigated by using focus group interview (FGI) with 30 women who participated in consumer organizations. Results: The main target groups for the education program were housewives (H), parents (P), and the office workers (OW), for which we considered their influences on other people and the surroundings. According to the results of FGI, in carrying out low sodium diet, 'positive outcome expectation' were prevention of chronic disease and healthy dietary habit, and 'negative outcome expectation' were low palatability of foods, difficulty in cooking meals, and limited choice of foods. The contents of the program and education materials were individualized by each group to raise self-efficacy and behavioral capability, which reflected the results of the FGI. The program included 'salt intake and health' to raise positive outcome expectation. For improving the ability to practice low-sodium diet, the program contained the contents that focused on 'cooking' and 'food purchasing' for H, on 'purchasing and selection of low-sodium food with the children' for P, and on 'way of selecting restaurant menu' for OW. Also the program included 'way of choosing the low-sodium foods when eating out' with suggestions on sodium content of the dishes and snacks. Further, 'dietary guidelines to reduce sodium intake' was also suggested to help self-regulation. Conclusions: This nutrition education program and education materials could be utilized for the community education and provide the basis for further consumer targeted education program for reducing sodium intake.

Objectives : This work aimed to review clinical trial trend of Korean medicine's face rejuvenation and suggest future trial using embedded needle(Maesun) based on Evidence-based medicine's PICO Model. Methods : 46 papers were searched from Oasis and DBPia, then 8 papers were engaged in review of clinical trial trend. Based on PICO model, clinical trial's patient, intervention, and outcome measurement were suggested. Results : Evidence level of clinical trials is relatively low, because their study designs are almost case report or case series. No study have comparison groups. Outcome measurement is varied, however, 3D face scanner were used to measure before-after changes of face. Based on review, we suggested that necessity of intervention standardization, measuring of normal control group and 2D/3D combined outcome measurement of face. Conclusions : There are many demands for revealing efficacy and safety of Korean medicine's intervention, also for face rejuvenation using embedded needle. For meeting the level of demands, more rigorous works are needed.

Objectives : Recent educational efforts have concentrated on patient's early hospital arrival after symptom onset. The purpose of this study was to evaluate the time interval between symptom onset and hospital arrival and to investigate its relation with clinical outcomes for patients with acute ischemic stroke. Methods : A prospective registry of patients with signs or symptoms of acute ischemic stroke, admitted to the OO Medical Center through emergency room, was established from September 2003 to December 2004. The interval between symptom onset and hospital arrival was recorded for each eligible patient and analyzed together with clinical characteristics, medication type, severity of neurologic deficits, and functional outcomes. Results : Based on the data of 256 patients, the median interval between symptom onset and hospital arrival was 13 hours, and 22% of patients were admitted to the hospital within 3 hours after symptom onset. Patients of not-mild initial severity and functional status showed significant differences between arrival hours of 0-3 and later than 3 in terms of their functional outcomes on discharge. Logistic regression models also showed that arrival within 3 hours was a significant factor influencing functional outcome (OR=5.6; 95% CI=2.1, 15.0), in addition to patient's initial severity, old age, cardioembolism subtype, and referral to another hospital. Conclusions : The time interval between symptom onset and hospital arrival significantly influenced treatment outcome for patients with acute ischemic stroke, even after controlling for other significant clinical characteristics. The findings provided initiatives for early hospital arrival of patients and improvement of emergency medical system.

Objectives : To investigate the association of trial registration status with presence of reporting bias including publication bias and outcome reporting bias in recently published randomized controlled trials (RCTs) of acupuncture. Methods : A PubMed search for RCTs of acupuncture published from March 2016 to February 2017 was conducted. Primary outcomes were identified and the direction of the results was judged as positive (i.e., statistically significant) or negative. The trial registration was identified by manually screening the trial registration number in the main text of the published article and classified into 1) prospective registration; 2) retrospective registration based on the registration date or; 3) no registration. Results : Of the 125 included RCTs, only 40 studies (32.0%) prospectively registered the study protocols. Among 65 RCTs that adequately reported the primary outcome, unregistered trials were more likely to report positive results than the registered ones (p=0.013). Of the 40 prospectively registered studies, 19 trials (47.5%) had the discrepancies between the registered and published primary outcomes and furthermore, 40% of them reported the positive findings. Conclusions : Unregistered trials were more likely to report positive results and the discrepancies between the registered and published primary outcomes were detected in about a half of the prospectively registered studies, 42.1% of which tended to report positive findings. Journal editors and researchers in this field should be alerted to various reporting biases.

Objectives : We retrospectively studied the efficacy of anterior cervical discectomy and interbody fusion without plate fixation in degenerative cervical disease. Methods : Thirty two consecutive patients with degenerative cervical disease treated by decompression and interbody fusion(Smith-Robinson technique) without anterior cervical plating were studied for postoperative complication rate as well as the clinical and radiologic outcomes and were compared the result of ours with other reported series where the anterior cervical plating was used. Results : All cases were reviewed after average period of 13 months for the purpose of this study. There were 4 postoperative complications related to grafting. A solid fusion was obtained in all cases with single-level fusion(n=21) and 81.8 % of the cases with a two-level fusion(n=11). The overall fusion rate was 93.8 % and fusion rate per level fused was 95.3%. The clinical outcome of the patients was comparable with that in the literature, with one patient having a poor result. Comparing the result of this study with others of the anterior cervical plating, clinical outcome and fusion rate were not superior in plate fixation group in single-level fusion, but increased fusion rate and decreased graft-related complication rate were noted in multilevel fusion with plate fixation. However, the clinical outcome was not superior to noninstrumented fusion group of this study. Conclusion : These results demonstrate that anterior cervical discectomy and interbody fusion(Smith-Robinson technique) without instrumentation is safe and reliable method of single-level fusion in degenerative cervical disease. Plate fixation system doesn't seem necessary in single level fusion in degenerative cervical disease.

Objectives : The goal of this study is to evaluate the usefulness of mild hypothermia treatment in patients with increased intracranial pressure(ICP). Material and Method : From November 1999 to May 2001, 11 patients were treated with mild hypothermia ($32-34^{\circ}C$) in whom ICP maintained at higher than 20mmHg in spite of decompressive surgery and high dose barbiturate therapy. The patient's rectal temperature were lowered by external cooling. Hypothermia was maintained for not more than 7 days and then the patients were rewarmed slowly for 24 hours. If increased ICP persisted for 2 days of hypothermia, this treatment was continued for several days. The functional outcome of each patient was assessed according to Glasgow Outcome Scale(GOS). Results : All cases except two cases showed decrease of ICP after hypothermia therapy. In 1 case which was right middle cerebral artery(MCA) infarct, ICP re-increased after 24 hours and in another 1 case, ICP was not controlled initially. Among 11 cases, 3 cases showed favorable outcome. Conclusion : Mild hypothermia treatment in patients with increased ICP was effective in controlling ICP and mortality was so decreased. More clinical experience and controlled study was need to determine the effectiveness.

This study aimed to identify curriculum gaps and a pilot study to provide the programs for selection during clerkship. Over the course of a clerkship, students analyze the current level and the needs level of TLO (terminal learning objectives) based on the book "Learning outcome of basic medical education: Scientific concept and principle-centered." We conducted a needs assessment utilizing a t-test, Borich Needs Assessment, and the Locus for Focus model. In the investigation of the needs level, the levels of the musculoskeletal and respiratory systems were relatively high and in the investigation of the current level, the levels of the digestive and musculoskeletal systems were relatively high. This study is expected to contribute to reasonable decision-making by utilizing various methods of analysis and providing in-depth results of needs analysis in designing clerkship curriculum.

Objectives: Previous pandemics have demonstrated that several demographic, geographic, and socioeconomic factors may play a role in increased infection risk. During this current coronavirus disease 2019 (COVID-19) pandemic, our aim was to examine the association of timing of lockdown at the county level and aforementioned risk factors with daily case rate (DCR) in the United States. Methods: A cross-sectional study using publicly available data was performed including Americans with COVID-19 infection as of May 24, 2020. The United States counties with >100 000 population and >50 cases per 100 000 people were included. The independent variable was the days required from the declaration of lockdown to reach the target case rate (50/100 000 cases) while the dependent (outcome) variable was the DCR per 100 000 on the day of statistical calculation (May 24, 2020) after adjusting for multiple confounding socio-demographic, geographic, and health-related factors. Each independent factor was correlated with outcome variables and assessed for collinearity with each other. Subsequently, all factors with significant association to the outcome variable were included in multiple linear regression models using stepwise method. Models with best R² value from the multiple regression were chosen. Results: The timing of mandated lockdown order had the most significant association on the DCR per 100 000 after adjusting for multiple socio-demographic, geographic and health-related factors. Additional factors with significant association with increased DCR include rate of uninsured and unemployment. Conclusions: The timing of lockdown order was significantly associated with the spread of COVID-19 at the county level in the United States.

Objectives: This study aimed to evaluate the effect of clinical factors on the outcome of arthrocentesis in the treatment of temporomandibular joint (TMJ) internal derangement. Materials and Methods: Fifty patients with TMJ internal derangement underwent arthrocentesis using ringer's lactate. The present study evaluated the contribution of the clinical variables of age, time since onset, visual analogue scale (VAS) pain level, and range of motion (ROM) on the outcomes of TMJ arthrocentesis: age (${\leq}25\;years$, >25 and ${\leq}40\;years$, >40 and ${\leq}60\;years$), VAS pain level (${\leq}5$, >5 and ${\leq}7$, >7 and ${\leq}10$), and ROM (<25 and ${\geq}25mm$). Odds ratios (ORs) were used to describe the proportional benefit of each variable the on successful outcome of arthrocentesis. For the OR to be clinically relevant or even clinically noticeable, we assumed that the OR would need to be larger than 2. Results: Mean preoperative pain score was $6.49{\pm}1.560$ and at 6 months postoperative was $0.46{\pm}1.147$ with an average decrease of pain score 6 (P<0.001). The mean preoperactive maximum mouth opening was $26.14{\pm}4.969mm$ and mean maximum mouth opening at 6-month inerval was $38.92{\pm}3.392mm$. The mean increase in the mouth opening was a mean difference of 12.78 mm (P<0.001). Logistic regression showed that the maximum benefit occurred in patients aged <25 years (OR, 12.01; P=0.012), a VAS pain level of >7 (OR, 11.25; P=0.039), and a maximum vertical opening of <25 mm (OR, 7.70; P=0.038). Conclusion: Lavage of the superior joint space with ringer's lactate resulted in significant reduction in pain and improvement in mouth opening. Patients with a greater inflammatory component and younger patients benefitted more from arthrocentesis. Evaluation of these clinical variables helped in predictive modelling, which may provide clinicians with the opportunity to identify "at-benefit" patients early and initiate specific treatment.

Objectives: The outcomes of the treatment of unilateral cleft lip can vary considerably due to variations in repair techniques. The aim of this study was to evaluate and compare treatment outcomes of surgical repair of unilateral cleft lip using either the Tennison-Randall or Millard technique based on (qualitative) parent/subject and professional assessments. Materials and Methods: This was a prospective, randomized, controlled study conducted at Lagos University Teaching Hospital between January 2013 and July 2014. A total of 56 subjects with unilateral cleft lip presenting for primary surgery who satisfied the inclusion criteria were recruited for the study. Subjects were randomly allocated to surgical groups A or B through balloting. Group A underwent cleft repair with the Tennison-Randall technique, while group B underwent cleft repair with the Millard rotation advancement technique. Surgical outcome was assessed using qualitative evaluation by the guardian/subject and independent assessors based on a modified form of the criteria described by Christofides and colleagues. Results: Of the 56 subjects enrolled in this study, 32 were male, with a male to female ratio of 1.3:1. Fifteen of the guardians/subjects in the Tennison-Randall group were most bothered about the lower part of the residual lip scar, while 12 guardians/subjects in the in the Millard group were most bothered about the upper part of the scar. More noses were judged to be flattened in the Millard group than in the Tennison-Randall group. Assessors observed a striking disparity in scar transgression of the philtral ridges between the two groups. Conclusion: Essentially, there were no major difference in the overall results between Millard rotation-advancement and Tennison-Randall repairs. Both Millard and Tennison-Randall's techniques require significant improvements to improve the appearance of the scar on the upper part and lower part of the lip, respectively.
