RESUMEN
Background@#The effectiveness of exercise for improving osteoporosis and fall prevention in patients diagnosed with osteoporosis or osteopenia has not been fully summarized. The Korean Society for Bone and Mineral Research and the Korean Society of Exercise Physiology has developed exercise guidelines for patients with osteoporosis or osteopenia and provide evidence-based recommendations. @*Methods@#A systematic review identified randomized controlled trials (RCT) assessing the effect of resistance, impact, balance, aerobic training, and physical activity in osteoporosis and osteopenia on bone quality, physical performance, quality of life, and fall prevention. PubMed, Embase, KoreaMed, and RISS were searched from January 2000 to August 2022. Ten key questions were established to review the evidence and formulate recommendations. @*Results@#The 50 RCTs reported that even with osteoporosis and osteopenia, resistance and impact training consistently maximized bone strength, improved body strength and balance, and eventually reduced fall incidences. Resistance exercise combining 3 to 10 types of free weight and mechanical exercise of major muscle groups performed with an intensity of 50% to 85% 1-repetition maximum, 5 to 12 repetitions/set, 2 to 3 days/week, for 3 to 12 months is recommended. Impact exercises such as jumping chin-ups with drop landings and jump rope performed 50 jumps/session for at least 6 months with 3 or more days/week are recommended. @*Conclusions@#A multi-component exercise mainly comprised of resistance and impact exercise seems to be an effective strategy to attenuate the risk factors of osteoporosis and osteopenia. The integration of exercise guidelines and individualized exercise plans has significant potential to reduce the morbidity and mortality of osteoporosis.
RESUMEN
Background@#Aging leads to significant bone loss and elevated osteoporosis risk. Exercise slows age-related bone loss; however, the effects of various moderate-intensity exercise training volumes on bone metabolism remain unclear. This study aimed to determine the degree to which different volumes of moderate-intensity aerobic exercise training influence bone mineral density (BMD), bone mineral content (BMC), femoral trabecular bone microarchitecture, and cortical bone in middle-aged mice. @*Methods@#Twenty middle-aged male C57BL/6 mice were randomly assigned 8 weeks of either (1) non-exercise (CON); (2) moderate-intensity with high-volume exercise (EX_MHV); or (3) moderate-intensity with low-volume exercise (EX_MLV) (N=6-7, respectively). Femoral BMD and BMC were evaluated using dual energy X-ray absorptiometry, and trabecular and cortical bone were measured using micro-computed tomography. @*Results@#Femoral BMD in EX_MHV but not EX_MLV was significantly higher (P<0.05) than in CON. The distal femoral fractional trabecular bone volume/tissue volume (BV/TV, %) was significantly higher (P<0.05) in both EX_MHV and EX_MLV than in CON mice. Increased BV/TV was induced by significantly increased trabecular thickness (mm) and tended to be higher (P<0.10) in BV (mm3) and lower in trabecular separation (mm) in EX_MHV and EX_MLV than in CON. The femoral mid-diaphysis cortical bone was stronger in EX_MLV than EX_MHV. @*Conclusions@#Long-term moderate-intensity aerobic exercise with low to high volumes can be thought to have a positive effect on hindlimb BMD and attenuate age-associated trabecular bone loss in the femur. Moderate-intensity aerobic exercise may be an effective and applicable exercise regimen to prevent age-related loss of BMD and BV.
RESUMEN
Objective@#The bedside on-site ultrasound examination is a very useful diagnostic test for medically ill elderly emergency patients. However, it is not known whether it is being sufficiently used in the real world scenario. We investigated this aspect in patients with chest pain in two emergency departments in the Seoul metropolitan area. @*Methods@#Elderly patients with chest pain who visited the two emergency departments from January 2019 to December 2019 were recruited using the ‘cardiogenic pain’ code, which is the third step classification of the Korean Triage and Acuity Scale, and their medical records were reviewed to confirm whether an emergency physician-performed ultrasound prescription code was entered. @*Results@#Of the 744 elderly patients with chest pain, 66 were given bedside on-site ultrasound examinations. The rate of examination was 8.8%. Among the emergency departments, the local emergency departments accounted for 33 out of 389 patients (8.5%), and the regional emergency department accounted for 33 out of 355 (9.3%). @*Conclusion@#These results raise the need to check the extent of bedside on-site ultrasound examinations that are conducted in the initial care of medically ill emergency elderly patients nationwide.

RESUMEN
PURPOSE: The Korean Triage and Acuity Scale (KTAS), which was developed in 2012 due to the need for a single triage tool for emergency patients in Korea, has since become nationalized. Although five years has passed, there has been limited evidence of its validation. Therefore, this study was conducted to analyze the validity of the new triage system. METHODS: We conducted a multicenter prospective study. Data were collected from seven hospitals and 42,187 patients were classified using the KTAS from April 1, 2013 to July 6, 2014. We analyzed whether the indirect severity variables showed meaningful differences according to KTAS levels. The variables consisted of disposition from emergency room, length of stay, numbers of consultations, examination of computed tomography, emergency room costs, and performance of emergent interventions. RESULTS: From KTAS level 1 to 5, a decreasing trend in the length of stay in emergency room, frequency of consultation with other departments, admission, computed tomography rate, emergency intervention rate, and emergency room costs was observed. Upon binominal logistic regression, disposition from emergency room and emergent intervention rate showed the highest odds ratio with statistical significance. CONCLUSION: The results of this study demonstrated that KTAS is a valid emergency triage tool that reflects the severity of the patient with indirect indicators. The results of this study will be useful as a reference for quality control of KTAS.

OBJECTIVE: We aimed to describe electrocardiographic (ECG) findings in spontaneous pneumothorax patients before and after closed thoracostomy. METHODS: This is a retrospective study which included patients with spontaneous pneumothorax who presented to an emergency department of a tertiary urban hospital from February 2005 to March 2015. The primary outcome was a difference in ECG findings between before and after closed thoracostomy. We specifically investigated the following ECG elements: PR, QRS, QTc, axis, ST segments, and R waves in each lead. The secondary outcomes were change in ST segment in any lead and change in axis after closed thoracostomy. RESULTS: There were two ECG elements which showed statistically significant difference after thoracostomy. With right pneumothorax volume of greater than 80%, QTc and the R waves in aVF and V5 significantly changed after thoracostomy. With left pneumothorax volume between 31% and 80%, the ST segment in V2 and the R wave in V1 significantly changed after thoracostomy. However, majority of ECG elements did not show statistically significant alteration after thoracostomy. CONCLUSION: We found only minor changes in ECG after closed thoracostomy in spontaneous pneumothorax patients.

Pneumopericardium is defined as the presence of air inside the pericardial space. Usually, it is reported as a complication of blunt or penetrating chest trauma, but rare iatrogenic and spontaneous cases have been reported. Pneumopericardium is relatively stable if it does not generate a tension effect on the heart. However, it may progress to tension pneumopericardium, which requires immediate pericardial aspiration. We report a case of iatrogenic pneumopericardium occurred in a 70-year-old man who presented dyspnea at emergency department. The patient underwent pericardiocentesis for cardiac tamponade due to large pericardial effusion, and iatrogenic tension pneumopericardium occurred due to misuse of the drainage device. After evacuating the pericardial air through the previously implanted catheter, the patient became stable. We report this case to increase the awareness of this fatal condition and to help increase the use of precautions against the development of this condition during emergency procedures.

The survival rate of commotio cordis is low, and there is often associated neurological disability if return of spontaneous circulation (ROSC) can be achieved. We report a case of commotio cordis treated with therapeutic hypothermia (TH) that demonstrated a favorable outcome. A 16-year-old female was transferred to our emergency department (ED) for collapse after being struck in the chest with a dodgeball. She has no history of heart problems. She was brought to our ED with pulseless ventricular tachycardia (VT), and ROSC was achieved with defibrillation. She was comatose at our ED and was treated with TH at a target temperature of 33degrees C for 24 hours. After transfer to the intensive care unit, pulseless VT occurred, and defibrillation was performed twice. She recovered to baseline neurologic status with the exception of some memory difficulties.

PURPOSE: The aim of this study was to investigate the independent factors associated with the registration rate for the community-based post suicidal care program in the emergency department (ED). METHODS: This prospective observational study was conducted between March and December 2013 at the academic ED at the tertiary urban hospital. During the study period, the pre-designed registry was recorded. The variables examined included the following: patients' demographic data (Sex, age, address, type of insurance, marital status, level of education, and history of previous psychiatric disease), suicide-related data (suicidal methods, combined drink of alcohol and number of previous attempts), and management-related data (disposition at ED, physician's training level, etc.). Univariated and multivariated logistic regression analyses were performed for identification of factors affecting the registration rate for the community-based post suicidal care program. RESULTS: A total of 163 suicides were included during the study period. Of these, 33 (20.2%) patients were registered in the post-suicide care program. Factors including a patient's address (OR: 14.92, 95% CI: 3.606-61.711), immediate intervention by psychiatric healthcare center (OR: 5.05, CI: 1.688-15.134), admissions in hospital (OR: 3.69, CI: 1.286-10.605), and history of previous psychiatric disease (OR: 3.52, CI: 1.216-10.201) showed significant association with registration for the program. CONCLUSION: The community-based post-suicidal care program, which is available 24 hours a day, should be operated in each district in order to increase the registration rate. Emergency physicians should actively consider the inpatient treatment program for suicidal patients and strongly recommend registration to the program, particularly for patients without previous history of psychiatric disease.

PURPOSE: As a first step towards reform of the emergency medical service system, we aimed to assess the current status of our emergency department triage systems and illustrated the current status and problems of the Korean emergency department triage system. METHODS: We conducted e-mail and telephone surveys of the triage officers of all 136 emergency medical centers in Korea. RESULTS: All 136 emergency departments responded to the survey. In Korea, a triage scale derived from the 'emergency symptoms based on the requirements of the Emergency Medical Service Act' is the most-used triage scale. We identified factors showing significant association with use of verified triage vs. unverified scales, including level of triage scale, type of hospital, type of emergency department, perception of problems regarding the triage scale, educational performance, and number of annual visits. CONCLUSION: Results of our survey showed that in Korea various kinds of triage scale are in use and the reliability and validity of more than half of them are unverified. Reform of the Korean national triage system is in progress and our survey findings should be helpful in guiding reorganization of the national triage systems of many countries.
