Aim:The aim of the present study was to evaluate the clinical characteristics, including floor characteristics and factors, related to severe injury from outdoor falls in older adults.Methods: Patients were divided into two groups based on injury severity: the severe group and non-severe group. The clinical and general characteristics were compared between the two groups, and factors associated with severe injury were investigated.Results: Approximately 5% (364/7635) of older people involved in outdoor falls were classified into severe injury. The proportion of men and the rate of alcohol ingestion were higher in the severe group compared with that in the nonsevere group. Falling from stairs was a more frequent mechanism of fall in the severe group compared with that in the non-severe group. Non-slippery floor condition had a higher proportion in the severe group than that in the nonsevere group. Head and neck were the predominantly injured regions in both groups. Discharge was the most common result of emergency department treatment in the non-severe group, whereas admission to intensive care unit was the main result in the severe group. Multivariate logistic analysis showed that male sex and falls from stairs rather than slipping down on the same level were associated with severe injury.Conclusions: Floor characteristics did not influence injury severity; however, the risk of severe injury from outdoor falls in older adults was high in men and those who fell from stairs.

BackgroundFalls from low-height can cause severe injuries in the elderly population. This study was conducted to determine characteristics of injuries from low-height falls.MethodsWe retrospectively review surveillance data on injured patients who presented to six emergency departments from January 2011 to December 2015. Study subjects were divided into severe group and non-severe group based on severity of injury. The general and clinical characteristics were compared between the two groups and analyzed factors related with severe injuries.ResultsOf 1,190 elderly patients, severe group comprised 82 patients (7%). The severe group was 2 years younger than the non-severe group. In the severe group, 61% was men and 34% in the non-severe group. In the non-severe, the injuries more commonly occurred at residential facilities and indoors than those in the severe group. Paid work during injury occurrence was 15%, and the more patients presented with non-alert consciousness in the severe group. The most common regions of major injury were head and neck in the severe group.ConclusionPaid work, non-alert consciousness, and major injury to head and neck are relating factors to severe injuries in the elderly population.
Background This study aimed to examine the characteristics of older adults patients who suffered a head injury after a ground-level fall in comparison to non-head injury patients as well as the factors associated with severity in those with head injury only. Methods Patients were classified into two groups, the head injury group and the non-head injury group. The characteristics were compared and factors associated with head injury were evaluated. Factors relating to severe injury in the head injury group were also investigated. Results The head injury group comprised 42 % of a study subjects. Male sex; fall time of 18:00–23:59; fall location of medical facility, transportation area, and public or commercial facility; fall in an outdoor area; fall during daily activity; alcohol ingestion; fall from stairs; non-slippery floor conditions; concrete flooring; sloped flooring; and presence of obstacles on the floor were risk factors for head injury in the older adults after a ground-level fall. Male sex and age over 70 years; fall time of 00:00–05:59; fall in a residential facility; fall in an indoor area; fall during daily activity; fall from stairs; non-slippery floor conditions; and presence of obstacles on the floor were factors associated with severe injury in the head injury group. Conclusions Male sex with advanced age, indoor fall, and the presence of obstacles on the floor were risk factors for severe injury in the head injury group in older adults individuals who suffered a ground-level fall. It is necessary to develop appropriate ground-level fall prevention programs by evaluating the individual and environmental characteristics of older adults patients.
In traditional systems of medicine, fruits, leaves, and stems of Actinidia arguta (Sieb. et Zucc.) Planch. ex Miq. have been used to treat various inflammatory diseases. The present study determined the proximate composition, antioxidant, anti-inflammatory, and hypoglycemic potential of A. arguta stem. Phenolic composition of hot water extract and its sub-fractions was determined by Folin-Ciocalteu's reagent method. In vitro antioxidant activities of the samples were evaluated using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) radical scavenging assays. Anti-inflammatory activity of different fractions was investigated through the inhibition of nitric oxide (NO) production in lipopolysaccharide (1 μg/ml) stimulated RAW 264.7 cells. In addition, inhibition of α-glucosidase activity of hot water extract was determined using p-nitrophenyl-α-d-glucopyranoside (pNPG) as a substrate. Ethyl acetate (557.23 mg GAE/g) fraction contains higher level of total phenolic content. The antioxidant activity evaluated by DPPH radical scavenging assay showed a strong activity for ethyl acetate (IC50 of 14.28 μg/ml) and n-butanol fractions (IC50 of 48.27 μg/ml). Further, ethyl acetate fraction effectively inhibited NO production in RAW 264.7 cells induced by lipopolysaccharide (LPS) than other fractions (nitrite level to 32.14 μM at 200 μg/ml). In addition, hot water extract of A. arguta stem exhibited appreciable inhibitory activity against α-glucosidase enzyme with IC50 of 1.71 mg/ml. The obtained results have important consequence of using A. arguta stem toward the development of effective anti-inflammatory drugs.
Purpose: The purpose of this study was to investigate the epidemiologic characteristics of patients who visited emergency departments (EDs) after intentional poisoning in Korea. Methods: This study retrospectively analyzed the data of of 23 hospitals during a five-year period, between 2011 and 2015. We included patients who inflicted injury to themselves - attempt of suicide - by means of poisoning. Results: A total of 18,121 patients visited an ED after intentional poisoning. Among them, 58.3% were females; however, there were more males among those aged 60 years or older. The mortality rate for males was 8.6%, which was 3.1 times higher than that for females with 2.8%. The most common poison was pesticides (35.4%) in males and sedative-hypnotics (44.0%) in females. The most common causative agent of death was pesticide in both sexes (75.2% and 65.3%, respectively). Since the production of paraquat was discontinued in 2011, the number of deaths from pesticide poisoning has decreased. The mortality rate declined in both males and females, from 12.6% and 4.5% in 2011 to 7.1% and 2.1% in 2015, respectively. Conclusion: In this study, we analyzed the epidemiologic characteristics of intentional poisoning, especially the frequency of suicide attempts by gender and age group, the cause of suicide, and the causative agent. This can be used as basic data for establishing policies to reduce and prevent suicide attempts by poisoning.
