Background Hand injuries caused by chain saws, electric saws, and hand grinders range from simple lacerations to tendon injuries, fractures, and even amputations. This study aimed to understand the distribution of various types of hand and upper extremity injuries caused by power tools, in order to help prevent them, by investigating the incidence and cause of power tool injuries treated over a 4-year period at a single institution in Korea. Methods We reviewed the medical records of patients who visited a single institution for power tool-induced injuries from 2011 to 2014. The distribution of sex, age, injured body part, type of injury, and mechanism of injury sustained by patients who received hand and upper extremity injuries from using an engine saw, electric saw, or hand grinder was evaluated. Results Among 594 subjects who were injured by power tools, 261 cases were hand and upper extremity injuries. The average age was 53.2 years. Tendon injury was the most common type of injury. An electric saw was the most common type of power tool used. More injuries occurred in non-occupational settings than in occupational settings. Conclusions In this study, power tool-induced hand and upper extremity injuries were mostly caused by direct contact with electric saw blades. More injuries occurred due to non-occupational use of these tools, but the ratios of amputations and structural injuries were similar in the non-occupational and occupational groups.

Objectives: The purpose of this study is to identify the relationship between metabolic syndrome factor diseases and falls in the elderly aged 65 years or older and use them as basic data to reduce the risk of falls. Methods: The method of this study was to compare the injury-related characteristics of the fall and non-fall groups with a factor disease of metabolic syndrome in Korea over 65 years of age. Data from the 14th National Hospital Discharge In-depth Injury Survey in 2018 were used to conduct the study. A total of 7,991 data were analyzed using SPSS 23.0. Results: Among the total injuries, the fall group with metabolic syndrome factor disease accounted for 69.0% and the non-fall group 31.0%. Falls occurred in 86.3% of households. In the fall group with metabolic syndrome factor disease, the number of females was 1.9~2.1 times higher than that of males. Compared to 65~69 years of age, the incidence of falls was 1.4~1.5 times higher in 70~79 years, 1.7~2.2 times higher in 80~89 years, and 2.5~3.6 times higher in 90-year-olds and older. In NISS, the incidence of falls was 1.7 times higher in moderate compared to mild. In principle diagnosis, the incidence of falls was 2.2 times higher in S40-S99 compared to S00-S19. Conclusion: The elderly with metabolic syndrome factor disease should continue to promote health through light exercise that can strengthen muscle strength to prevent falls.

It is known that chronic pain and injury of upper limb joint tissue in manual wheelchair users is usually caused by muscle imbalance, and the propulsion speed is reported to increase this muscle imbalance. In this study, kinematic variables, electromyography, and ultrasonographic images of the upper limb were measured and analyzed at two different propulsion speeds to provide a quantitative basis for the risk of upper extremity joint injury. Eleven patients with spinal cord injury for the experimental group (G_E) and 27 healthy adults for the control group (G_C) participated in this study. Joint angles and electromyography were measured while subjects performed self-selected comfortable and fast-speed wheelchair propulsion. Ultrasound images were recorded before and after each propulsion task to measure the acromiohumeral distance (AHD). The range of motion of the shoulder (14.35 deg in G_E; 20.24 deg in G_C) and elbow (5.25 deg in G_E; 2.57 deg in G_C) joints were significantly decreased (p<0.001). Muscle activation levels of the anterior deltoid, posterior deltoid, biceps brachii, and triceps brachii increased at fast propulsion. Specifically, triceps brachii showed a significant increase in muscle activation at fast propulsion. AHD decreased at fast propulsion. Moreover, the AHD of G_E was already narrowed by about 60% compared to the G_C from the pre-tests. Increased load on wheelchair propulsion, such as fast propulsion, is considered to cause upper limb joint impingement and soft tissue injury due to overuse of the extensor muscles in a narrow joint space. It is expected that the results of this study can be a quantitative and objective basis for training and rehabilitation for manual wheelchair users to prevent joint pain and damage.

Purpose: This scoping review aimed to synthesize the characteristics and effects of interventions designed to prevent unintentional home injuries in older adults in Korea. Methods: The review was conducted following the Joanna Briggs Institute protocol. A literature search was performed for studies published between 2001 and 2022 in the DBPia, RISS, KMBase, and NDSL databases. A total of 1,620 studies were identified, and 27 studies were included in the final analysis. Data were analyzed for characteristics of the literature, intervention-related unintentional injury mechanisms, and safety areas. Results: Most selected studies utilized a quasi-experimental design and targeted elderly women. In terms of injury mechanisms, 21 of 27 studies focused on falls, 2 on fire/disaster, 3 on drugs, and 1 on food. The most common preventive intervention for falls was exercise, and its effectiveness was verified using physical safety variables. Interventions in the fire/disaster, drug, and food domains were all educational, and changes in knowledge, behavior, and attitude were verified. Conclusion: This study confirmed the effectiveness of interventions for preventing unintentional injuries in the homes of community-dwelling older adults. These findings can serve as a foundation for developing and implementing unintentional injury prevention interventions at home for community-dwelling older adults. Multidisciplinary research is needed to address multifaceted safety issues by considering the home environment and injury risk factors.

Background: A previous study has shown that Euonymus alatus (EA) has an antidotic activities against inflammation, suggesting possibility that EA can exert this beneficial effects to liver injury by an initial protection against drug-induced hepatocyte demage. The present study was undertaken to evaluate the protective effect of EA-extract on experimentally induced hepatitis in ICR mice and to investigate some mechanisms responsible for its action. Methods: Water EA extract was used in this experiments. The mice received i.p. a dose of 700 mg/kg galactosamine (GalN) together with $5{\mu}g/kg$ of endotoxin (LPS), or received i.v. 12 mg/kg of concanavalin A (Con A). EA (4 mg/mouse) was administrated on day -2, -1 and 0 before induction of liver injury. Liver injury was assessed by measurement of serum alanin amino-transferase (SGPT) levels on 9 hr after GaIN.LPS, or 8 hr after con A administration. Results: Treatment with either GaIN or LPS alone did not cause hepatitis. However, simultaneous administration of GalN and LPS to mice resulted in LPS-dose dependent fulminant hepatitis. GaLN/LPS-induced liver injury was reduced when mice were given EA for 3 days before induction. This preventive effect of Ea was more prominent when EA was given by intraperitoneal route rather then by oral route. Pretreatment of EA or dexamethasone inhibited significantly $TNF{\alpha}$ production in GalL/LPS-injured mice. However, EA-treatment did not influence $TNF{\alpha}$-induced hepatitis in GalN-sensitized mice, suggesting that $TNF{\alpha}$ is likely to act as one of final mediators of endotoxin action and the protective effect of EA might be manifested chiefly by inhibition of endotoxin-induced $TNF{\alpha}$ production, not by blocking the $TNF{\alpha}$-action. Injection of Con A into mice evoked remarkable liver injury in a dose dependent fashion. This liver damage was reduced by EA-pretreatment. Dexamethasone significantly reduced both GalL/LPS-induced and Con A-induced liver damages, showing synergism with EA. However, indomethacin reduced only GalN/ LPS-induced hepatitis, not for Con A-induced hepatitis. Conclusion: These results led to the conclusion that EA may be able to contribute at least in part to prevent the drug-induced hepatotoxicity, and that its anti-hepatitis effects might be manifested directly by modulation of endogenous mediators, such as leukotriese D4, $TNF{\alpha}$ and free radical, and indirectly by regulation of immune mediated responses. Also these results suggested that EA could be developed as a potential antidotic agent.

스포츠 선수는 경기 중 발생할 수 있는 몸싸움과 격렬한 동작으로 인해 항상 구강악안면 외상에 노출되어 있음에도 불구하고 구강보호장치는 불편하고 불필요하다는 인식이 강한편이다. 그러나 구강보호장치는 외부 충격 시 치아를 보호하고, 응력을 분산시키는 역할 등 스포츠 선수에게 없어서는 안 될 중요 예방대책이다. 그렇기 때문에 스포츠 선수들의 불편하고 불필요하다는 인식을 개선시켜줄 필요가 있고, 스포츠 선수의 구강 보호차원에서 구강보호장치의 사용을 일반화 하는 것이 중요하다 할 수 있다. 본 연구는 스포츠 선수 290명을 대상으로 구강보호장치 사용 실태를 조사하여 착용 경험율 6.6%, 현재 착용률 3.8%, 사용할 필요성 25.9%, 사용할 의사 28.3%인 결과를 얻어 스포츠 선수들의 구강보호장치 사용률과 인식모두 매우 낮은 실정을 알 수 있었고, 성별, 연령, 신체 접촉 정도, 구강악안면 외상경험, 외상 대처법 교육경험에 따라 구강보호장치 사용률에 변화가 있는지 분석한 결과, 사용률이나 인식이 남성과 고연령층이 높다는 것을 알 수 있었고, 신체 접촉이 많은 종목과 구강악안면 외상경험, 구강악안면 외상대처법 교육경험이 있는 스포츠 선수가 구강보호장치 사용률과 인식이 조금 더 높은 것으로 나타났다. 따라서 아직까지 스포츠 선수에게 구강보호장치에 대한 인식과 사용은 매우 낮은 실정이지만 경험과 교육을 통해 충분히 개선될 수 있고 향후 스포츠 선수들의 구강보호를 위해 많은 교육이 필요할 것으로 사료된다.

Currently, liver transplantation is the only available remedy for patients with end-stage liver disease. Conservation of transplanted liver graft is the most important issue as it directly related to patient survival. Carbonyl reductase 1 (CBR1) protects cells against oxidative stress and cell death by inactivating cellular membrane-derived lipid aldehydes. Ischemia-reperfusion (I/R) injury during living-donor liver transplantation is known to form reactive oxygen species. Thus, the objective of this study was to investigate whether CBR1 transcription might be increased during liver I/R injury and whether such increase might protect liver against I/R injury. Our results revealed that transcription factor Nrf2 could induce CBR1 transcription in liver of mice during I/R. Pre-treatment with sulforaphane, an activator of Nrf2, increased CBR1 expression, decreased liver enzymes such as aspartate aminotransferase and alanine transaminase, and reduced I/R-related pathological changes. Using oxygen-glucose deprivation and recovery model of human normal liver cell line, it was found that oxidative stress markers and lipid peroxidation products were significantly lowered in cells overexpressing CBR1. Conversely, CBR1 knockdown cells expressed elevated levels of oxidative stress proteins compared to the parental cell line. We also observed that Nrf2 and CBR1 were overexpressed during liver transplantation in clinical samples. These results suggest that CBR1 expression during liver I/R injury is regulated by transcription factor Nrf2. In addition, CBR1 can reduce free radicals and prevent lipid peroxidation. Taken together, CBR1 induction might be a therapeutic strategy for relieving liver I/R injury during liver transplantation.
