Purpose: The purpose of the study was to investigate the correlation between injury and injury severity score (ISS) in geriatric traffic accident patients transported by 119 emergency medical technicians (EMTs). Methods: The subjects were 240 traffic accident patients over 65 years old transported by 119 rescue services emergency departments in Busan from January 1, 2014 to August 31, 2015. Results: ISS increased in motorcycle traffic accidents (p=.026), truck injuries (p=.005), and head and neck injury (p<.001). Vital signs were evaluated by 119 rescue EMT. ISS increased in cases of unresponsive unconsciousness (p<.001), hypotension (p=.001), and bradycardia (p<.001). The need for bleeding control and dressing by the EMTs increased ISS significantly (p=.022). Conclusion: In the initial evaluation of geriatric traffic patients, ISS can increase in motor cycle accidents and truck injuries. Due to high ISS, patients with head and neck injury, chest injury, hypotension, or tachycardia should be transferred to advanced level hospitals.

Purpose: This study investigated the effect of pressure injury nursing knowledge, and pressure injury nursing attitudes, on pressure injury nursing practice. Methods: Participants in this descriptive study were 141 nurses at 20 geriatric hospitals. Data was collected August 24, 2021- April 4, 2022, and analyzed in terms of Independent t-test and one-way ANOVA, Scheffé test, Pearson's correlation coefficient, and multiple regression, using the SPSS/WIN 27.0 program. Results: Pressure injury nursing practice positively correlated with pressure injury nursing attitudes (r= .44, p< .001). Factors influencing pressure injury nursing practice were pressure injury nursing attitudes (β= .43, p< .001), and gender (β= .21, p= .006). The model used in this study explains 22.8% of pressure injury nursing practice (Adjusted R²= 22.8, F= 11.30, p< .001). Conclusion: Results show factors that influence pressure injury nursing practice of nurses in geriatric hospitals. Based on the results, pressure injury nursing practice programs must include factors that improve pressure injury nursing attitudes. A follow-up study to confirm the impact of developing a program for increasing pressure injury nursing practice is also recommended.

Purpose: Recently, the population of elderly people has been increasing rapidly all over the world. The social activities of the aging population have increased, which has also increased the number of elderly patients injured in traffic accidents. Thus, we analyzed the characteristics of elderly patients involved in traffic accidents. Methods: This study was conducted retrospectively from July 2008 to March 2009 among trauma patients involved in traffic accidents who visited Wonju Severance Christian Hospital. Patients under 18 years of age and pregnant patients were excluded. We divided the patients in two groups, a geriatrics group and an adult group on the basis of an age of 65. We compared the types of traffic accidents, the locations of the accidents, the behaviors of the patients at the times of the accidents, the use of seat-belts, and alcohol consumption between the two groups. We calculated the Revised Trauma Score (RTS), Injury Severity Score (ISS), and Trauma and Injury Severity Score (TRISS) for each group. Results: Total number of the included patients was 903, and the number of elderly patients was 181 (mean age: $71.7{\pm}4.9$ years old). There were no significant differences in the initial vital signs, GCS (Glasgow Coma Scale), and RTS between the two groups. There were differences in the types and the locations of the crashes, the behaviors of the patients at the times of the accidents, the use of seat belts, and alcohol consumption between the two groups (p<0.05). The average ISS of the geriatric group was higher than that of the adult group ($9.66{\pm}10.11$ vs. $6.59{\pm}8.99$, p=0.004). The mortality was higher in the geriatric group (n=17,9%) than in the adult group (n=23,2%) (p=0.004). Conclusion: The numbers of mortalities and surgical procedures were greater within the elderly group than the adult group. The average ISS was higher in the geriatric group than in the adult group. The severity of injuries due to traffic accidents was higher in the geriatric group than it was in the adult group.

Purpose: This study examined the characteristic of the Injury Severity Score (ISS) of Korean geriatric patients with a traumatic injury in a nationally representative sample to determine the optimal cutoff of ISS of mortality according to age. Methods: The subjects were 3,018 non-elderly patients and 1,584 elderly patients with an ISS and Korean Triage and Acuity Scale (KTAS) in 2016 from the data of the Health Insurance Review and Assessment Service. The traumatic characteristics of the elderly and non-elderly were compared by stratifying the ISS. Receiver Operating Characteristic (ROC) curve analysis was used to find the optimal cutoff of ISS of mortality according to age. Results: The elderly were more prone to severe trauma than the non-elderly were. The distribution of KTAS grades was lower, even though the severity of ISS was as high as that of the non-elderly. The optimal cutoff score of the ISS for mortality in the ROC curve was lower in elderly over 65 years than in the other age group. Conclusion: The elderly are more prone to severe trauma and death than non-elderly, even though their ISS is low. Therefore, a strategy to prevent elderly from experiencing serious trauma and managing their geriatric trauma actively is needed.

Purpose: Many factors influence the occurrence and severity of geriatric trauma, and regional weather is regarded as one factor that influences geriatric trauma. In this study, to predict the type, severity, and incidence of geriatric trauma patient, we analyzed the influence of regional weather on geriatric trauma. Methods: The subjects of our investigation were trauma patients over sixty-five years of age who visited the Emergency Department (ED) of Yeungnam University Hospital during a one-year period. We retrospectively reviewed the medical charts of 436 geriatric trauma patients, and the data were analyzed by using SPSS 12.0 for Window. The weather was based on data from the Korea Meteorological Administration. Results: The average age was 72.8 years old, and the ratio of males to females was 1:1.1. The mean spell out ISS was 10.8, and no difference was found between males and females. Slips were the most common cause of trauma. The largest numbers of aged trauma patients, 46, visited the ED in May, and the smallest number of such patients, 24, visited the ED in December. In addition to, summer saw the largest number of aged trauma patients. The type of trauma, the Injury Severity Score, and the number of patients had no relationship with season. On sunny days, the ISS was larger in patients who had hypotension and who had tachycardia. On rainy day, the ISS was larger in male patients and cultivator accident patients. The number of patients was larger on partly cloudy days. Conclusion: In spring and summer and on partly cloudy days, we must be prepared to treat aged traumatized patients in the E.D. On rainy days, visual sensation, tactual sense, and acoustic sense must be closely examined. In addition,on rainy day, aged male traumatized patients or cultivator accident patients must to be closely observation.

Objective : Although traumatic brain injury (TBI) occurs in people of all age groups, the elderly population is at a particular risk. The proportion of elderly population in the society is markedly increasing and Korea is one of the most rapidly aging societies. Here, we analyzed the data from 904 patients older over 65 years who were registered in the Korean Neuro-Trauma Data Bank System (KNTDBS). Methods : The Korean Society of Neurotraumatology recorded data from 20 institutions between September 2010 and March 2014. This retrospective study examined the clinical epidemiology, sex difference, outcome epidemiology, sociodemographic variables, and outcomes in the geriatric population related to TBI based on data from the KNTDBS. Results : The study included 540 men and 364 women. The age distributions in the male and female groups were statistically significantly different. The most common cause of trauma was a fall and diagnosis was acute subdural hematoma. The incidence was the highest in men aged 80-84 years and in women aged 75-79 years. The most common time of arrival to hospital after TBI was within 1 hour and 119 rescue team provided first aid earliest to patients with TBI. The mortality rate stratified according to the cause of trauma was significantly different, with mortality rates of 3.77% in fall and 11.65% in traffic accident. The mortality rates according the severity of brain injury, Glasgow Coma Scale score, and treatment were statistically significant. Conclusion : To our knowledge, this study is the first to focus on elderly patients with TBI in Korea and particularly investigate mortality and characteristics related to TBI-related death based on data from the KNTDBS. Although the study has some limitations, our results may be used to obtain useful information to study targeted prevention and more effective treatment options for older TBI patients and establish novel treatment guidelines and health polish for the geriatric population.

Purpose: The use of surgical stabilization of rib fractures (SSRF) has steadily increased over the past decade. Recent literature suggests that a larger population may benefit from SSRF, and that the geriatric population-as the highest-risk population-may receive the greatest improvement from these interventions. We sought to determine the overall utilization of SSRF in the United States. Methods: The National Trauma Database was analyzed between 2016 and 2017. The inclusion criteria were all patients ≥65 years old with rib fractures. We further stratified these patients according to age (65-79 vs. ≥80 years old), the presence of coding for flail chest, three or more rib fractures, and intervention (surgical vs. nonoperative management). The main outcomes were surgical interventions, mortality, pneumonia, length of stay, intensive care unit length of stay, ventilator use, and tracheostomy. Results: Overall, 93,638 patients were identified. SSRF was performed in 992 patients. Patients who underwent SSRF had improved mortality in the 65 to 79 age group, regardless of the number of ribs fractured. We identified 92,637 patients in the age group of 65 to 79 years old who did not undergo SSRF. This represents an additional 20,000 patients annually who may benefit from SSRF. Conclusions: By conservative standards and the well-established Eastern Association for the Surgery of Trauma clinical practice guidelines, SSRF is underutilized. Our data suggest that SSRF may be very beneficial for the geriatric population, specifically those aged 65 to 79 years with any rib fractures. We hypothesize that roughly 20,000 additional cases will meet the inclusion criteria for SSRF each year. It is therefore imperative that we train acute care surgeons in this skill set.

Cigarette smoke extract (CSE)-treated mouse airway epithelial cells (MAECs)-derived exosomes accelerate the progression of chronic obstructive pulmonary disease (COPD) by upregulating triggering receptor expressed on myeloid cells 1 (TREM-1); however, the specific mechanism remains unclear. We aimed to explore the potential mechanisms of CSE-treated MAECs-derived exosomes on M1 macrophage polarization and pyroptosis in COPD. In vitro, exosomes were extracted from CSE-treated MAECs, followed by co-culture with macrophages. In vivo, mice exposed to cigarette smoke (CS) to induce COPD, followed by injection or/and intranasal instillation with oe-TREM-1 lentivirus. Lung function and pathological changes were evaluated. CD68⁺ cell number and the levels of iNOS, TNF-α, IL-1β (M1 macrophage marker), and pyroptosis-related proteins (NOD-like receptor family pyrin domain containing 3, apoptosis-associated speck-like protein containing a caspase-1 recruitment domain, caspase-1, cleaved-caspase-1, gasdermin D [GSDMD], and GSDMD-N) were examined. The expression of maternally expressed gene 3 (MEG3), spleen focus forming virus proviral integration oncogene (SPI1), methyltransferase 3 (METTL3), and TREM-1 was detected and the binding relationships among them were verified. MEG3 increased N6-methyladenosine methylation of TREM-1 by recruiting SPI1 to activate METTL3. Overexpression of TREM-1 or METTL3 negated the alleviative effects of MEG3 inhibition on M1 polarization and pyroptosis. In mice exposed to CS, EXO^-CSE further aggravated lung injury, M1 polarization, and pyroptosis, which were reversed by MEG3 inhibition. TREM-1 overexpression negated the palliative effects of MEG3 inhibition on COPD mouse lung injury. Collectively, CSE-treated MAECs-derived exosomal long non-coding RNA MEG3 may expedite M1 macrophage polarization and pyroptosis in COPD via the SPI1/METTL3/TREM-1 axis.

Falls are a leading cause of injury, disability and death among people older than 65. Even without injury, falls cause a loss of confidence that results in reduced physical activity, increased dependency and social withdrawal. Fall prevention in the eldery people is a multifaced task that includes both the identification of risk factors and their modification strategies. Fall risk factors have been identified as both intrinsic and extrinsic. Intrinsic factors are those related to the physical and cognitive function of the person. Extrinsic factors are those which are included in the environmental hazards of everyday life. Combinations of interventions aimed at modifying both intrinsic and extrinsic risk factors can result in significant fall prevention in the geriatric population. This article selectively reviews the literature reporting exercise intervention to improve strength, balance and mobility.
