Objective: The aim of this study was to evaluate the clinical characteristics of heat stroke in a bath facility and investigate predictive factors of multiple major complications in heat stroke patients. Methods: This was a retrospective study on heat stroke patients who visited an urban emergency center from January 2010 to March 2018. We compared clinical characteristics, complication, and outcomes of heat stroke patients in bath and non-bath facilities. Multivariate logistic regression analysis were performed to identify independent predictors of multiple major complications in heat stroke patients. Results: A total of 67 heat stroke patients with heat stroke were enrolled, of which 42 (62.6%) were in a bath facility and 25 (37.3%) were in a non-bath facility. Patients with heat stroke in the bath facility were characterized by old age, past medical history of hypertension and diabetes mellitus, and high incidence of hypotension compared with those in the non-bath facility but also low incidence of acute renal failure, seizure, and multiple major complications. In the multivariate analysis, predictive factors of multiple major complications in heat stroke patients were non-bath facility (odds ratio [OR], 5.4; 95% confidence interval [CI], 1.2-29.9), Glasgow Coma Scale (GCS)${\leq}8$ (OR, 8.2; 95% CI, 1.3-49.4), and mean arterial pressure (MAP), body temperature above $40.5^{\circ}C$ (OR, 8.1; 95% CI, 1.1-58.8) <60 mmHg (OR, 14.8; 95% CI, 1.8-122.9). Conclusion: Heat stroke in the bath facility resulted in less major complications, and high body temperature, GCS ${\leq}8$, and MAP <60 mmHg were independent predictive factors of multiple major complications in heat stroke patients.

Background : To improve medication adherence in elderly patients, the role of pharmacists in teambased services has been highlighted in the literature. However, not much is known about the role and the service elements involved in comprehensive geriatric programs in South Korea. This study was designed to describe the current status of medication adherence in geriatric patients based on the comprehensive geriatric assessment program and analyze the predictive factors for medication adherence in a tertiary teaching hospital. Methods : A retrospective cohort study was performed using electronic medical records of 247 patients from March 1st, 2015 to August 31st, 2015. Medication adherence and the types of non-adherence were also collected. Predictive factors for adherence were evaluated by including factors related to demographics, medications, illness, and patterns of medical usage. Results : The mean age of the study population was 81.2 years (range 65~98 years) and they were taking 9.7 drugs on an average (SD 5.0 drugs). The overall rate of non-adherence was 34%. About 48% of the patients had any forms of assistance in the medication administration. The most common type of non-adherence was "self-adjustment". The multivariate analyses revealed that age (adjusted odds ratio, 0.87 [95% CI, 0.80-0.96]; p 0.05) and the number of inappropriate medications (adjusted odds ratio, 0.59 [95% CI, 0.40-0.89]; p 0.05) were strong predictors for non-adherence. Conclusions : These results indicate that strategic considerations of the predictors of non-adherence should be improved in medication counseling services targeting elderly patients.

Purpose: This study was done to assess nursing students' practice of patient safety management (PSM), identify factors affecting PSM and provide basic data to develop education programs to strengthen students' competencies for patient safety. Methods: In this descriptive research the practice of PSM by nursing students was examined and predictive factors were identified. Participants were junior and senior nursing students from 7 universities in 7 cities. Self-report questionnaires were used for data collection. Results: Significant positive correlations were found between knowledge of PSM, perception of the importance of PSM and practice of PSM. In multivariate analysis, women students, participation in patient safety education in school, knowledge of PSM, and practice of PSM predicted high perception of the importance of PSM. In multivariate analysis, senior year and participation in patient safety education in school predicted higher knowledge of PSM. In multivariate analysis, perception of the importance of PSM predicted high practice of PSM. Conclusion: In this study, knowledge was not found to directly affect PSM practice, but was found to affect the perception of the importance of PSM, a significant predictive variable. Thus, the importance of PSM should be strongly emphasized during education.

This study examines the reporting factors of crime against business in Korea and proposes a corresponding predictive model using machine learning. While many previous studies focused on the individual factors of theft victims, there is a lack of evidence on the reporting factors of crime against a business that serves the public good as opposed to those that protect private property. Therefore, we proposed a crime prevention model for the willingness factor of theft reporting in businesses. This study used data collected through the 2015 Commercial Crime Damage Survey conducted by the Korea Institute for Criminal Policy. It analyzed data from 834 businesses that had experienced theft during a 2016 crime investigation. The data showed a problem with unbalanced classes. To solve this problem, we jointly applied the Synthetic Minority Over Sampling Technique and the Tomek link techniques to the training data. Two prediction models were implemented. One was a statistical model using logistic regression and elastic net. The other involved a support vector machine model, tree-based machine learning models (e.g., random forest, extreme gradient boosting), and a stacking model. As a result, the features of theft price, invasion, and remedy, which are known to have significant effects on reporting theft offences, can be predicted as determinants of such offences in companies. Finally, we verified and compared the proposed predictive models using several popular metrics. Based on our evaluation of the importance of the features used in each model, we suggest a more accurate criterion for predicting var.

This study is a descriptive research attempted to examine the exercise practice of junior high school students and figure out their changing process, decision-making balance, and self-efficacy according to the exercise practice so that they can be utilized as fundamental data for developing exercise intervention programs for junior high school students. The study subjects were students from five junior high schools in B City. Total 600 questionnaires were distributed, and 554 responded ones were analyzed. The collected data were analyzed using SPSS/Win 10.0. According to the results of analyzing the subjects with the exercise changing stage tool, exercise non-practice group including the precontemplation stage, contemplation stage, and preparation stage occupies 57.6% while the exercise practice group including the action stage and maintenance stage consists of 42.4%. And according to the results of discriminating analysis setting total 10 factors of transtheoretical model variables as predictive factors to predict each group based on whether they practice exercise or not, it was found out that the subordinate factors of the changing process, consciousness-raising (F=33.98, p=.000), self-cognitive decision (F=21.55, p=.000), contrary condition provision (F=84.67, p=.000), helping relationship (F=28.52, p=.000), reinforced thinking (F=14.15, p=.000), and stimulus control (F=54.64, p=.000), and the subordinate factors of the decision-making balance, beneficial factors (F=15.65, p= .000) and hindering factors (F=8.58, p=.004), and self-efficacy (F=78.60. p=.000) were significant predictive factors and discriminating variables. Based on the research findings above, it will be necessary to develop exercise intervention programs sufficiently reflecting the changing process, decision-making balance, and self-efficacy suitably for the subjects and make strategies to encourage their active participation and exercise maintenance, through verifying transtheoretical model variables according to whether the junior high school students practice exercise or not.

Purpose: The aim of this study was to utilize the American College of Surgeons Trauma Quality Improvement Program (TQIP) database to identify risk factors associated with developing acute compartment syndrome (ACS) following lower extremity fractures. Specifically, a nomogram of variables was constructed in order to propose a risk calculator for ACS following lower extremity trauma. Methods: A large retrospective case-control study was conducted using the TQIP database to identify risk factors associated with developing ACS following lower extremity fractures. Multivariable regression was used to identify significant risk factors and subsequently, these variables were implemented in a nomogram to develop a predictive model for developing ACS. Results: Novel risk factors identified include venous thromboembolism prophylaxis type particularly unfractionated heparin (odds ratio [OR], 2.67; 95% confidence interval [CI], 2.33-3.05; P<0.001), blood product transfusions (blood per unit: OR 1.13 [95% CI, 1.09-1.18], P<0.001; platelets per unit: OR 1.16 [95% CI, 1.09-1.24], P<0.001; cryoprecipitate per unit: OR 1.13 [95% CI, 1.04-1.22], P=0.003). Conclusions: This study provides evidence to believe that heparin use and blood product transfusions may be additional risk factors to evaluate when considering methods of risk stratification of lower extremity ACS. We propose a risk calculator using previously elucidated risk factors, as well as the risk factors demonstrated in this study. Our nomogram-based risk calculator is a tool that will aid in screening for high-risk patients for ACS and help in clinical decision-making.

Purpose: Despite the high incidence of abdominal stab injuries, the rate of nontherapeutic laparotomies and the predictors of therapeutic laparotomies have rarely been studied in low-income settings. Methods: This multicenter retrospective study involved three of the largest academic medical centers in central Ethiopia. All patients who sustained an anterior abdominal stab injury and underwent exploratory laparotomy, regardless of the intraoperative findings, were included over the 3-year course of the study. Results: Of the 117 patients who underwent exploratory laparotomy, 35 patients (29.9%) underwent nontherapeutic laparotomies. Three factors predicted therapeutic laparotomy: hollow viscus evisceration (adjusted odds ratio [AOR], 5.77; 95% confidence interval [CI], 1.16-28.64; P=0.032), localized and generalized peritonitis (AOR, 4.77; 95% CI, 1.90-11.93; P=0.001), and white blood cell count ≥11,500/mm³ (AOR, 2.77; 95% CI, 1.002-7.650; P=0.049). The overall positive predictive value of the therapeutic predictors was 80.2%, while the negative predictive value of all predictor-negative patients was 58.1%. The predictors would have prevented 51.4% of the nontherapeutic laparotomies. Conclusions: Close to one-third of the patients had a nontherapeutic laparotomy. The clinical predictors of therapeutic laparotomy were shown to have a high positive predictive value despite a lower negative predictive value. Further prospective studies that involve all patients who sustain anterior abdominal stab injuries are needed to potentially improve on the negative predictive value of the predictors suggested by our study.

Background: Breast cancer is a very common health problem in Iranian women. The HER2-neu gene is a transmembrane receptor tyrosine kinase with homology to members of the EGF receptor family. The aim of this study was to investigate the association between HER2-neu oncogene status with prognostic factors of breast cancer in Kermanshah province, Iran. Materials and Methods: Relationship between HER2-neu and prognostic factors of 130 cases of breast cancer were evaluated during two years in Imam Reza hospital in Kermanshah, Iran. Data were analyzed using descriptive statistics and the T-test and Mann-Whitney U non-parametric test using SPSS 19. Results: The mean age for the patients was $46.0{\pm}8.0years$, all being female. Among the predictive factors for breast cancer were family history, stage of disease, involvement of the lymphovascular system, number of involved lymph nodes in axillaries, grading and hormone receptor status with HER2-neu oncogene had direct correlation and between factors, tumor location, patient age and histological characteristics and HER2-neu oncogene had no significant relationship. We found significant correlation between HER2 with ER and PR and also HER2 with ER, PR negative. Conclusions: HER2-neu is risk factor that can be a good prognostic and also predictive factor. For these reasons, we recommend that it be evaluated for all types of BC.
