    To investigate prescribing pattern in low-dose aspirin users and physician awareness of preventing aspirin-induced gastrointestinal (GI) injury with combined protective medications. A retrospective drug utilization study was conducted in the 2nd Affiliated Hospital, School of Medicine, Zhejiang University. The hospital has 2300 beds and 2.5 million outpatient visits annually. Data mining was performed on all aspirin prescriptions for outpatients and emergency patients admitted in 2011. Concomitant use of proton-pump inhibitors (PPIs), histamine 2-receptor antagonists (H2RA) and mucoprotective drugs (MPs) were analyzed. A defined daily dose (DDD) methodology was applied to each MP. A further investigation was performed in aspirin users on combination use of GI injurious medicines [non-steoid anti-inflammatory drugs (NSAIDs), corticosteroids and clopidogrel and warfarin] or intestinal protective drugs (misoprostol, rebamipide, teprenone and gefarnate). Data of major bleeding episodes were derived from medical records and adverse drug reaction monitoring records. The annual incidence of major GI bleeding due to low-dose aspirin was estimated for outpatients. Prescriptions for aspirin users receiving PPIs, H2RA and MPs (n = 1039) accounted for only 3.46% of total aspirin prescriptions (n = 30 015). The ratios of coadministration of aspirin/PPI, aspirin/H2RA, aspirin/MP and aspirin/PPI/MP to the total aspirin prescriptions were 2.82%, 0.12%, 0.40% and 0.12%, respectively. No statistically significant difference was observed in age between patients not receiving any GI protective medications and patients receiving PPIs, H2RA or MPs. The combined medication of aspirin and PPI was used more frequently than that of aspirin and MPs (2.82% vs 0.40%, P teprenone > sucralfate oral suspension > L-glutamine and sodium gualenate granules > rebamipide > sucralfate chewable tablets. The ratio of MP plus aspirin prescriptions to the total MP prescriptions was as follows: rebamipide

    Several studies suggest a link between autoimmunity and essential hypertension in humans. However, whether autoimmunity can drive the development of hypertension remains unclear. The autoimmune disease systemic lupus erythematosus is characterized by autoantibody production, and the prevalence of hypertension is increased markedly in this patient population compared with normal healthy women. We hypothesized that preventing the development of autoimmunity would prevent the development of hypertension in a mouse model of lupus. Female lupus (NZBWF1) and control mice (NZW) were treated weekly with anti-CD20 or immunoglobulin G antibodies (both 10 mg/kg, IV) starting at 20 weeks of age for 14 weeks. Anti-CD20 therapy markedly attenuated lupus disease progression as evidenced by reduced CD45R+ B cells and lower double-stranded DNA autoantibody activity. In addition, renal injury in the form of urinary albumin, glomerulosclerosis, and tubulointerstitial fibrosis, as well as tubular injury (indicated by renal cortical expression of neutrophil gelatinase-associated lipocalin) was prevented by anti-CD20 therapy in lupus mice. Finally, lupus mice treated with anti-CD20 antibody did not develop hypertension. The protection against the development of hypertension was associated with lower renal cortical tumor necrosis factor-α expression, a cytokine that has been previously reported by us to contribute to the hypertension in this model, as well as renal cortical monocyte chemoattractant protein-1 expression and circulating T cells. These data suggest that the development of autoimmunity and the resultant increase in renal inflammation are an important underlying factor in the prevalent hypertension that occurs during systemic lupus erythematosus.

    Full Text Available The babysitter-procedure might offer an alternative when nerve reconstruction is delayed in order to overcome muscular atrophy due to denervation. In this study we aimed to show that a sensomotoric babysitter-procedure after median nerve injury is capable of preserving irreversible muscular atrophy. The median nerve of 20 female Wistar rats was denervated. 10 animals received a sensory protection with the N. cutaneous brachii. After six weeks the median nerve was reconstructed by autologous nerve grafting from the contralateral median nerve in the babysitter and the control groups. Grasping tests measured functional recovery over 15 weeks. At the end of the observation period the weight of the flexor digitorum sublimis muscle was determined. The median nerve was excised for histological examinations. Muscle weight (P<0.0001 was significantly superior in the babysitter group compared to the control group at the end of the study. The histological evaluation revealed a significantly higher diameter of axons (P=0.0194, nerve fiber (P=0.0409, and nerve surface (P=0.0184 in the babysitter group. We conclude that sensory protection of a motor nerve is capable of preserving muscule weight and we may presume that metabolism of the sensory nerve was sufficient to keep the target muscle’s weight and vitality.

  14. PINK1-Parkin-Mediated Mitophagy Protects Mitochondrial Integrity and Prevents Metabolic Stress-Induced Endothelial Injury.

    Directory of Open Access Journals (Sweden)

    Weiwei Wu

    Full Text Available Mitochondrial injury and dysfunction, a significant feature in metabolic syndrome, triggers endothelial cell dysfunction and cell death. Increasing evidence suggests that mitophagy, a process of autophagic turnover of damaged mitochondria, maintains mitochondrial integrity. PINK1 (phosphatase and tensin homolog (PTEN-induced putative kinase 1 and Parkin signaling is a key pathway in mitophagy control. In this study, we examined whether this pathway could protect mitochondria under metabolic stress. We found that palmitic acid (PA induced significant mitophagy and activated PINK1 and Parkin in endothelial cells. Knocking down PINK1 or Parkin reduced mitophagy, leading to impaired clearance of damaged mitochondria and intracellular accumulation of mitochondrial fragments. Furthermore, PINK1 and Parkin prevented PA-induced mitochondrial dysfunction, ROS production and apoptosis. Finally, we show that PINK1 and Parkin were up-regulated in vascular wall of obese mice and diabetic mice. Our study demonstrates that PINK1-Parkin pathway is activated in response to metabolic stress. Through induction of mitophagy, this pathway protects mitochondrial integrity and prevents metabolic stress-induced endothelial injury.

    2010-01-01

    Evidence for preventive strategies to lessen running injuries is needed as these occur in 40%-50% of runners on an annual basis. Many factors influence running injuries, but strong evidence for prevention only exists for training modification primarily by reducing weekly mileage. Two anatomical factors - cavus feet and leg length inequality - demonstrate a link to injury. Weak evidence suggests that orthotics may lessen risk of stress fracture, but no clear evidence proves they will reduce the risk of those athletes with leg length inequality or cavus feet. This article reviews other potential injury variables, including strength, biomechanics, stretching, warm-up, nutrition, psychological factors, and shoes. Additional research is needed to determine whether interventions to address any of these will help prevent running injury.

    Agriculture ranks fourth among U.S. industries for work-related fatalities (1). Fatalities associated with agricultural machinery commonly involve farm tractors, and rollover incidents (i.e., the tractor tips sideways or backward and overturns, crushing the operator) account for 46% (Minnesota) to 76% (Georgia) of all farm tractor-related fatalities (2). Annually, agricultural tractor rollovers result in approximately 132 work-related deaths among persons aged > or = 16 years* (3). This report summarizes information regarding the efficacy, effectiveness, and cost-effectiveness of rollover protective structures (ROPS) on agricultural tractors.

    Children and adolescents are now participating in competitive sports at younger ages and with increasing intensity. As a result, increasing numbers of young athletes are presenting to pediatricians for care of sports-related injuries and advice about prevention. Understanding and identifying modifiable risk factors for injury in the young athletic population is a critical first step in injury prevention. Risk factors vary by sport, age, and sex. This article reviews the most common risk factors for injury and the evidence to support proposed strategies for prevention. [Pediatr Ann. 2017;46(3):e99-e105.]. Copyright 2017, SLACK Incorporated.

    Current management of radiation-induced liver injury is limited. Sinusoidal endothelial cell (SEC) apoptosis and inflammation are considered to be initiating events in hepatic damage. We hypothesized that mesenchymal stem cells (MSCs) possess anti-apoptotic and anti-inflammatory actions during hepatic irradiation, acting via paracrine mechanisms. This study aims to examine whether MSC-derived bioactive components are protective against radiation-induced liver injury in rats. MSC-conditioned medium (MSC-CM) was generated from rat bone marrow-derived MSCs. The effect of MSC-CM on the viability of irradiated SECs was examined by flow cytometric analysis. Activation of the Akt and ERK pathways was analyzed by western blot. MSC-CM was also delivered to Sprague-Dawley rats immediately before receiving liver irradiation, followed by testing for pathological features, changes in serum hyaluronic acid, ALT, and inflammatory cytokine levels, and liver cell apoptosis. MSC-CM enhanced the viability of irradiated SECs in vitro and induced Akt and ERK phosphorylation in these cells. Infusion of MSC-CM immediately before liver irradiation provided a significant anti-apoptotic effect on SECs and improved the histopathological features of injury in the irradiated liver. MSC-CM also reduced the secretion and expression of inflammatory cytokines and increased the expression of anti-inflammatory cytokines. MSC-derived bioactive components could be a novel therapeutic approach for treating radiation-induced liver injury. © The Author 2015.

    2005-06-01

    A wide range of head and neck injury risks are present in sport, including catastrophic injury. The literature since 1980 on prevention of head and neck injury in sport was reviewed, focusing on catastrophic and brain injury and identifying the range of injury prevention methods in use. There have been few formal evaluations of injury prevention methods. Approaches that are considered, or have been proven, to be successful in preventing injury include: modification of the baseball; implementation of helmet standards in ice hockey and American football and increased wearing rates; use of full faceguards in ice hockey; changes in rules associated with body contact; implementation of rules to reduce the impact forces in rugby scrums. Helmets and other devices have been shown to reduce the risk of severe head and facial injury, but current designs appear to make little difference to rates of concussion. Research methods involving epidemiological, medical, and human factors are required in combination with biomechanical and technological approaches to reduce further injury risks in sport.

  4. DA-1229, a dipeptidyl peptidase IV inhibitor, protects against renal injury by preventing podocyte damage in an animal model of progressive renal injury.

    Although dipeptidyl peptidase IV (DPPIV) inhibitors are known to have renoprotective effects, the mechanism underlying these effects has remained elusive. Here we investigated the effects of DA-1229, a novel DPPIV inhibitor, in two animal models of renal injury including db/db mice and the adriamycin nephropathy rodent model of chronic renal disease characterized by podocyte injury. For both models, DA-1229 was administered at 300 mg/kg/day. DPPIV activity in the kidney was significantly higher in diabetic mice compared with their nondiabetic controls. Although DA-1229 did not affect glycemic control or insulin resistance, DA-1229 did improve lipid profiles, albuminuria and renal fibrosis. Moreover, DA-1229 treatment resulted in decreased urinary excretion of nephrin, decreased circulating and kidney DPPIV activity, and decreased macrophage infiltration in the kidney. In adriamycin-treated mice, DPPIV activity in the kidney and urinary nephrin loss were both increased, whereas glucagon-like peptide-1 concentrations were unchanged. Moreover, DA-1229 treatment significantly improved proteinuria, renal fibrosis and inflammation associated with decreased urinary nephrin loss, and kidney DPP4 activity. In cultured podocytes, DA-1229 restored the high glucose/angiotensin II-induced increase of DPPIV activity and preserved the nephrin levels in podocytes. These findings suggest that activation of DPPIV in the kidney has a role in the progression of renal disease, and that DA-1229 may exert its renoprotective effects by preventing podocyte injury.

    Full Text Available Injuries are one of the most under-recognized public health problems facing the world today. With more than 5 million deaths every year, violence and injuries account for 9% of global mortality, as many deaths as from HIV, Malaria and Tuberculosis combined. Eight of the 15 leading causes of death for people ages 15 to 29 years are injury-related: road traffic injuries, suicides, homicides, drowning, burns, war injuries, poisonings and falls. For every death due to war, there are three deaths due to homicide and five deaths due to suicide. However, most violence happens to people behind closed doors and results not in death, but often in years of physical and emotional suffering [1]. Injuries can be classified by intent: unintentional or intentional. Traffic injuries, fire-related injuries, falls, drowning, and poisonings are most often classified as unintentional injuries; injuries due to assault, selfinflicted violence such as suicide, and war are classified as intentional injuries, or violence. Worldwide, governments and public and private partners are increasingly aware of the strains that unintentional injuries and violence place on societies. In response they are strengthening data collection systems, improving services for victims and survivors, and increasing prevention efforts [1].

    Full Text Available A review was conducted to present current views and effectiveness of prevention and rehabilitation methods of hamstring injuries. Methods: a review searching on the electronic data bases, including Proquest, Medline, Sport Discus, Cinahl plus, Health source Nursing / Academic edition, Academic search complete, Pub med and Scholar Google. Only randomized control studies (RCT'S were included which contained the intervention and control groups concerning either the prevention or rehabilitation of hamstrings. Results: fourteen randomized control studies were included. Twelve concerned the prevention and two the rehabilitation of hamstring injuries. From the analysis of the articles concerning prevention we concluded that stretching, especially static and warm up program named "The 11" did not show any benefits in preventing hamstring injuries whilst strength training exercises with eccentric contraction (Nordic exercises and warm-up program "The 11+" containing eccentric exercises of hamstring showed significant differences regarding the prevention. It is postulated that the effectiveness of this may be due to the fact that the researchers had targeted the progressive increase in the intensity and frequency of eccentric exercises. Conclusions: eccentric exercises seem (based on the findings included in this study to have an important role in the prevention and strengthening immediately after hamstring injury and also significantly role on reducing the risk of reinjury. A rehabilitation program that includes mainly stretching exercises with eccentric loading of hamstrings muscles and secondly an exercise program which includes core stability and progressive agility exercises were found to be the most effective for recovery after hamstrings injury.

    1991-10-01

    The evolution of rules and regulations governing the development and use of protective football equipment for the prevention of craniofacial and intraoral traumatic injuries to football players have reduced substantially the occurrence of these injuries. Protective football equipment such as helmets, facemasks, and intraoral mouthguards have undergone numerous developmental changes to improve their effectiveness in preventing traumatic injuries to the head, face, and mouth of participants in football during practice sessions as well as in game situations. Unfortunately, however, some of these types of injuries do continue to occur. Various regulatory agencies and football governing bodies have established quality performance standards for equipment and have enacted rulings for their proper use. Penalties have been assessed for rule infractions to aid in curtailing the misuse of such equipment, as occurs for example, when the helmet is used to spear tackle an opponent or when the facemask is grasped, pulled, or twisted by an opposing player. Dentists can contribute significantly to the overall well-being of their patients who participate in football by providing information and advice regarding the proper use of protective football equipment to prevent craniofacial and intraoral traumatic football-related injuries, by fabricating properly fitted mouthguards as one aspect of their total practice of dentistry, and by providing high-quality and expeditious emergency and long-term treatment subsequent to football-related intraoral traumatic injuries. In addition, dentists can contribute on a larger scale to the overall well-being of football athletes by participating in community service activities such as mouthguard days, as consultants to football teams, as team dentists, or as advisors to those interested in research and development to improve protective football equipment, and to those responsible for sponsoring more stringent regulations for player safety in

    2013-04-01

    Unintentional injury accounts for 40 percent of childhood deaths annually, most commonly from motor vehicle crashes. The proper use of child restraints is the most effective strategy to prevent injury or death. Motor vehicle restraint guidelines have recently been revised to an age-based system that delays the progression in type of restraint for most children. Strategies to prevent suffocation in children include using appropriate bedding, positioning babies on their backs to sleep, and removing items from the sleep and play environment that could potentially entrap or entangle the child. Fencing that isolates a swimming pool from the yard and surrounding area and "touch" adult supervision (i.e., an adult is in the water and able to reach and grab a child) have been shown to be most effective in preventing drownings. Swimming lessons are recommended for children older than four years. Poison prevention programs have been shown to improve prevention behavior among caregivers, but may not decrease poisoning incidence. Syrup of ipecac is not recommended. Smoke detector maintenance, a home escape plan, and educating children about how to respond during a fire emergency are effective strategies for preventing fire injuries or death. Fall injuries may be reduced by not using walkers for infants and toddlers or bunk beds for children six years and younger. Consistent helmet use while bicycling reduces head and brain injuries. Although direct counseling by physicians appears to improve some parental safety behaviors, its effect on reducing childhood injuries is uncertain. Community-based interventions can be effective in high-risk populations.

    Full Text Available Jeffrey A Russell Division of Athletic Training, School of Applied Health Sciences and Wellness, Ohio University, Athens, OH, USA Abstract: Dancers are clearly athletes in the degree to which sophisticated physical capacities are required to perform at a high level. The standard complement of athletic attributes – muscular strength and endurance, anaerobic and aerobic energy utilization, speed, agility, coordination, motor control, and psychological readiness – all are essential to dance performance. In dance, as in any athletic activity, injuries are prevalent. This paper presents the research background of dance injuries, characteristics that distinguish dance and dancers from traditional sports and athletes, and research-based perspectives into how dance injuries can be reduced or prevented, including the factors of physical training, nutrition and rest, flooring, dancing en pointe, and specialized health care access for dancers. The review concludes by offering five essential components for those involved with caring for dancers that, when properly applied, will assist them in decreasing the likelihood of dance-related injury and ensuring that dancers receive optimum attention from the health care profession: (1 screening; (2 physical training; (3 nutrition and rest; (4 specialized dance health care; and (5 becoming acquainted with the nature of dance and dancers.

    Crossen, Eric J; Lewis, Brenna; Hoffman, Benjamin D

    2015-02-01

    Firearms are involved in the injury and death of a large number of children each year from both intentional and unintentional causes. Gun ownership in homes with children is common, and pediatricians should incorporate evidence-based means to discuss firearms and protect children from gun-related injuries and violence. Safe storage of guns, including unloaded guns locked and stored separately from ammunition, can decrease risks to children, and effective tools are available that pediatricians can use in clinical settings to help decrease children's access to firearms. Furthermore, several community-based interventions led by pediatricians have effectively reduced firearm-related injury risks to children. Educational programs that focus on children's behavior around guns have not proven effective. © American Academy of Pediatrics, 2015. All rights reserved.

    Triathlon is a popular participation sport that combines swimming, cycling and running into a single event. A number of studies have investigated the incidence of injury, profile of injuries sustained and factors contributing to triathlon injury. This paper summarises the published literature in the context of the evidence base for the prevention of triathlon related injuries. Relevant articles on triathlon injuries were sourced from peer-reviewed English language journals and assessed using the Translating Research into Injury Prevention Practice (TRIPP) framework. This review highlights the significant knowledge gap that exists in the published literature describing the incidence of injury, the profile of injuries sustained and evidence for the prevention of injury in triathlon. Despite the number of studies undertaken to address TRIPP Stages 1 and 2 (injury surveillance, aetiology and mechanism of injury), most triathlon studies have been limited by retrospective designs with substantial, and unvalidated, recall periods, inconsistency in the definitions used for a reportable injury and exposure to injury, or a failure to capture exposure data at all. Overall, the paucity of quality, prospective studies investigating the incidence of injury in triathlon and factors contributing to their occurrence has led to an inability to adequately inform the development of injury prevention strategies (TRIPP Stages 3-6) for this sport, a situation that must be rectified if gains are to be made in reducing the burden of triathlon related injury.

  1. Ecdysterone protects gerbil brain from temporal global cerebral ischemia/reperfusion injury via preventing neuron apoptosis and deactivating astrocytes and microglia cells.

    Ecdysterone (EDS), a common derivative of ecdysteroid, has shown its effects on alleviating cognitive impairment and improving the cognition and memory. However, the mechanisms remain unknown. Using temporal global forebrain ischemia and reperfusion-induced brain injury as a model system, we investigated the roles of EDS in improving cognitive impairment in gerbil. Our results demonstrated that intraperitoneal injection of EDS obviously increased the number of surviving neuron cells by Nissl and neuronal nuclei (NeuN) staining. Indeed, the protecting effects of EDS are because of its ability to prevent the apoptosis of neuron cells as evidenced by TUNEL staining and caspase-3 deactivation in the brain of temporal global forebrain ischemia/reperfusion-treated gerbil. Moreover, EDS administration suppressed the ischemia stimulated activity of astrocytes and microglia cells by inhibiting the production of tumor necrosis alpha (TNF-α) in the brain of gerbil. More importantly, these actions of neurons and astrocytes/microglia cells in response to EDS treatment played pivotal roles in ameliorating the cognitive impairment in the ischemia/reperfusion-injured gerbil. In view of these observations, we not only decipher the mechanisms of EDS in reducing the syndrome of ischemia, but also provide novel perspectives to combat ischemic stroke.

    Dancers are clearly athletes in the degree to which sophisticated physical capacities are required to perform at a high level. The standard complement of athletic attributes - muscular strength and endurance, anaerobic and aerobic energy utilization, speed, agility, coordination, motor control, and psychological readiness - all are essential to dance performance. In dance, as in any athletic activity, injuries are prevalent. This paper presents the research background of dance injuries, characteristics that distinguish dance and dancers from traditional sports and athletes, and research-based perspectives into how dance injuries can be reduced or prevented, including the factors of physical training, nutrition and rest, flooring, dancing en pointe, and specialized health care access for dancers. The review concludes by offering five essential components for those involved with caring for dancers that, when properly applied, will assist them in decreasing the likelihood of dance-related injury and ensuring that dancers receive optimum attention from the health care profession: (1) screening; (2) physical training; (3) nutrition and rest; (4) specialized dance health care; and (5) becoming acquainted with the nature of dance and dancers.

    The increasing participation in the athletic forms of bicycling warrants expanded physician attention to the traumatic and overuse injuries experienced by cyclists. The modern bicycle consists of a frame with various components, including handlebars, brakes, wheels, pedals, and gears, in various configurations for the various modes of cycling. For high performance cycling the proper fit of the bicycle is critical. The most efficient method to provide an accurate fit is the Fitkit, but proper frame selection and adjustment can be made by following simple guidelines for frame size, seat height, fore and aft saddle position, saddle angle, reach and handlebar height. The human body functions most effectively in a narrow range of pedal resistance to effort. Riding at too much pedal resistance is a major cause of overuse problems in cyclists. Overuse injuries are lower using lower gear ratios at a higher cadence. Cycling injuries account for 500,000 visits per year to emergency rooms in the US. Over half the accidents involve motor vehicles, and road surface and mechanical problems with the bicycle are also common causes of accidents. Head injuries are common in cyclists and account for most of the fatal accidents. Despite good evidence of their effectiveness, victims with head injuries have rarely worn helmets. Contusions, sprains and fractures may occur throughout the body, most commonly to the hand, wrist, lower arm, shoulder, ankle and lower leg. The handlebar and seat have been implicated in a wide variety of abdominal and genital injuries. Abrasions, lacerations and bruises of the skin are the most common traumatic injuries. Trauma may be prevented or reduced by proper protective safety equipment and keeping the bike in top mechanical condition. Anticipation of the errors of others and practising and adopting specific riding strategies also help to prevent traumatic injuries. Management of overuse injuries in cycling generally involves mechanical adjustment as well

    Chapman, R L; Buckley, L; Reveruzzi, B; Sheehan, M

    2014-08-01

    Unsafe road behaviors, violence and alcohol use, are primary contributors to adolescent injury. Research suggests that adolescents look out for their friends and engage in protective behavior to reduce others' risk-taking and that school connectedness is associated with reduced injury-risks. This study examined the role of school connectedness in willingness to protect and prevent friends from involvement in alcohol use, fights and unlicensed driving. Surveys were completed at two time points, six months apart, by 545 13-14 year olds from seven Australian high schools. Females were significantly more likely than males to report willingness to protect their friends. School connectedness significantly and positively predicted willingness to protect across all three injury-risk behaviors, after accounting for sex and own involvement in injury-risk behaviors. School connectedness may therefore be an important factor to target in school-based prevention programs, both to reduce adolescents' own injury-risk behavior and to increase injury prevention among friends.

    1993-07-01

    The use of weights is an increasingly popular conditioning technique, competitive sport and recreational activity among children, adolescents and young adults. Weight-training can cause significant musculoskeletal injuries such as fractures, dislocations, spondylolysis, spondylolisthesis, intervertebral disk herniation, and meniscal injuries of the knee. Although injuries can occur during the use of weight machines, most apparently happen during the aggressive use of free weights. Prepubescent and older athletes who are well trained and supervised appear to have low injury rates in strength training programmes. Good coaching and proper weightlifting techniques and other injury prevention methods are likely to minimise the number of musculoskeletal problems caused by weight-training.

    2015-09-01

    Online technology dominates our era and eHealth has become a reality for sports clinicians and researchers. Contemporary online platforms enable self-monitoring and provide tailored feedback to the different stakeholders who play a role in the health and care of athletes. Innovations such as digital monitoring, mobile applications and connected hardware provide the critical tools to solve current enigmas in sports medicine research, and to streamline and facilitate injury prevention, management and rehabilitation. eHealth is not an emerging future of sports medicine-the technology to move our field forward in terms of research and practice is already available. This Analysis is based on Evert Verhagen's keynote presentation at the IOC World Conference on Injury and Illness Prevention in Sport (Monaco, 12 April 2014). It outlines the use of eHealth in research, implementation and practice, and provides an overview of possibilities and opportunities that existing and emerging eHealth solutions provide for sports and exercise medicine and physiotherapy.

    Full Text Available This paper provided a brief summary of the current strategic goals, activities, and impacts of the NIOSH (National Institute for Occupational Safety and Health occupational injury research program. Three primary drivers (injury database, stakeholder input, and staff capacity were used to define NIOSH research focuses to maximize relevance and impact of the NIOSH injury-prevention-research program. Injury data, strategic goals, program activities, and research impacts were presented with a focus on prevention of four leading causes of workplace injury and death in the US: motor vehicle incidents, falls, workplace violence, and machine and industrial vehicle incidents. This paper showcased selected priority goals, activities, and impacts of the NIOSH injury prevention program. The NIOSH contribution to the overall decrease in fatalities and injuries is reinforced by decreases in specific goal areas. There were also many intermediate outcomes that are on a direct path to preventing injuries, such as new safety regulations and standards, safer technology and products, and improved worker safety training. The outcomes serve as an excellent foundation to stimulate further research and worldwide partnership to address global workplace injury problems.

  14. Prevention of Hamstring Injuries in Collegiate Sprinters

    Sugiura, Yusaku; Sakuma, Kazuhiko; Sakuraba, Keishoku; Sato, Yamato

    2017-01-01

    Background: No studies have been reported on how strength, agility, and flexibility training reduce the occurrence of hamstring injuries in sprinters. Therefore, a program for preventing hamstring injury in these athletes has not been established. Purpose: To document the incidence of hamstring injuries during times when different prevention strategies were employed to see whether a particular prevention program reduced their occurrence. Study Design: Descriptive epidemiology study. Methods: The study subjects were a total of 613 collegiate male sprinters trained by the same coach over 24 seasons. Tow training was used throughout the research period as a normal sprint training method. The hamstring injury prevention program evolved over time. From 1988 to 1991 (period 1), prevention focused on strength training alone; from 1992 to 1999 (period 2), a combination of strength and agility training was used; and from 2000 to 2011 (period 3), the program incorporated strength, agility, and flexibility training. The incidence of hamstring injuries was compared for each of the 3 prevention strategies. Results: The incidence of hamstring injuries per athlete-seasons was 137.9 for period 1, 60.6 for period 2, and 6.7 for period 3. A significant difference was observed in the incidence of hamstring injury according to the different prevention programs (χ2(2) = 31.78, P < .001, effect size: Cramer V = 0.23, 1 − β = 0.999). Residual analysis showed that the number of hamstring injuries for period 1 was significantly greater than the expected value (P < .01), whereas that for period 3 was significantly lower than the expected value (P < .01). Conclusion: The incidence of hamstring injuries in sprinters decreased as agility and flexibility were added to strength training. PMID:28210652

    Efforts to reduce the burden of injury and violence require a workforce that is knowledgeable and skilled in prevention. However, there has been no systematic process to ensure that professionals possess the necessary competencies. To address this deficiency, we developed a set of core competencies for public health practitioners in injury and violence prevention programs. The core competencies address domains including public health significance, data, the design and implementation of prevention activities, evaluation, program management, communication, stimulating change, and continuing education. Specific learning objectives establish goals for training in each domain. The competencies assist in efforts to reduce the burden of injury and violence and can provide benchmarks against which to assess progress in professional capacity for injury and violence prevention.

  20. Barefoot running: does it prevent injuries?

    Murphy, Kelly; Curry, Emily J; Matzkin, Elizabeth G

    2013-11-01

    Endurance running has evolved over the course of millions of years and it is now one of the most popular sports today. However, the risk of stress injury in distance runners is high because of the repetitive ground impact forces exerted. These injuries are not only detrimental to the runner, but also place a burden on the medical community. Preventative measures are essential to decrease the risk of injury within the sport. Common running injuries include patellofemoral pain syndrome, tibial stress fractures, plantar fasciitis, and Achilles tendonitis. Barefoot running, as opposed to shod running (with shoes), has recently received significant attention in both the media and the market place for the potential to promote the healing process, increase performance, and decrease injury rates. However, there is controversy over the use of barefoot running to decrease the overall risk of injury secondary to individual differences in lower extremity alignment, gait patterns, and running biomechanics. While barefoot running may benefit certain types of individuals, differences in running stance and individual biomechanics may actually increase injury risk when transitioning to barefoot running. The purpose of this article is to review the currently available clinical evidence on barefoot running and its effectiveness for preventing injury in the runner. Based on a review of current literature, barefoot running is not a substantiated preventative running measure to reduce injury rates in runners. However, barefoot running utility should be assessed on an athlete-specific basis to determine whether barefoot running will be beneficial.

  1. Core stability training for injury prevention.

    2013-11-01

    Enhancing core stability through exercise is common to musculoskeletal injury prevention programs. Definitive evidence demonstrating an association between core instability and injury is lacking; however, multifaceted prevention programs including core stabilization exercises appear to be effective at reducing lower extremity injury rates. PUBMED WAS SEARCHED FOR EPIDEMIOLOGIC, BIOMECHANIC, AND CLINICAL STUDIES OF CORE STABILITY FOR INJURY PREVENTION (KEYWORDS: "core OR trunk" AND "training OR prevention OR exercise OR rehabilitation" AND "risk OR prevalence") published between January 1980 and October 2012. Articles with relevance to core stability risk factors, assessment, and training were reviewed. Relevant sources from articles were also retrieved and reviewed. Stabilizer, mobilizer, and load transfer core muscles assist in understanding injury risk, assessing core muscle function, and developing injury prevention programs. Moderate evidence of alterations in core muscle recruitment and injury risk exists. Assessment tools to identify deficits in volitional muscle contraction, isometric muscle endurance, stabilization, and movement patterns are available. Exercise programs to improve core stability should focus on muscle activation, neuromuscular control, static stabilization, and dynamic stability. Core stabilization relies on instantaneous integration among passive, active, and neural control subsystems. Core muscles are often categorized functionally on the basis of stabilizing or mobilizing roles. Neuromuscular control is critical in coordinating this complex system for dynamic stabilization. Comprehensive assessment and training require a multifaceted approach to address core muscle strength, endurance, and recruitment requirements for functional demands associated with daily activities, exercise, and sport.

    2009-08-01

    Preventive medicine plays a central role in the reducing the number of deaths due to preventable causes of premature deaths. General Preventive Medicine Residency programs have not been studied in relation to training in this area. A three-wave mail survey was conducted with email and telephone follow-ups. The outcome measures were the portion of program directors involved in training residents on firearm injury prevention issues and their perceived benefits and barriers of training residents on firearm injury prevention issues. Only 25% of the programs provided formal training on firearm injury prevention. Program directors who provided formal training perceived significantly higher number of benefits to offering such training than did directors who did not provide such training but no significant difference was found between the two for number of perceived barriers. If preventive medicine residency graduates are to play a role in reducing premature morbidity and mortality from firearms it will require more residencies to offer formal training in this area. The Association for Prevention Teaching and Research needs to develop guidelines on specific curriculum topics regarding firearm injury prevention.

  6. Common Running Overuse Injuries and Prevention

    Directory of Open Access Journals (Sweden)

    Žiga Kozinc

    2017-09-01

    Full Text Available Runners are particularly prone to developing overuse injuries. The most common running-related injuries include medial tibial stress syndrome, Achilles tendinopathy, plantar fasciitis, patellar tendinopathy, iliotibial band syndrome, tibial stress fractures, and patellofemoral pain syndrome. Two of the most significant risk factors appear to be injury history and weekly distance. Several trials have successfully identified biomechanical risk factors for specific injuries, with increased ground reaction forces, excessive foot pronation, hip internal rotation and hip adduction during stance phase being mentioned most often. However, evidence on interventions for lowering injury risk is limited, especially regarding exercise-based interventions. Biofeedback training for lowering ground reaction forces is one of the few methods proven to be effective. It seems that the best way to approach running injury prevention is through individualized treatment. Each athlete should be assessed separately and scanned for risk factors, which should be then addressed with specific exercises. This review provides an overview of most common running-related injuries, with a particular focus on risk factors, and emphasizes the problems encountered in preventing running-related injuries.

  7. Recognition and Prevention of Rugby Injuries.

    Science.gov (United States)

    Tomasin, J D; Martin, D F; Curl, W W

    1989-06-01

    In brief: Rugby is a popular, strenuous contact sport that demands almost continuous action by the players. Players, coaches, and physicians must be aware of the potential for and types of injuries that occur during matches and of ways to avoid, or at least reduce, this number and severity. Minor and moderate injuries are more frequent than severe injuries, but all must be regarded seriously. Concussions, although relatively rare, can have serious consequences, and cervical spine injuries can be catastrophic. Player fitness and conditioning and a pregame warm-up are all essential for preventing injuries. Equally important are coaching, adherence to the rules of the game, and avoidance of dangerous play. If these measures are practiced consistently, rugby will be safer.

    Astrocytes in an in vitro murine astrocyte model of oxygen and glucose deprivation/hypoxia and reoxygenation were treated with different concentrations of triptolide (250, 500, 1 000 ng/mL) in a broader attempt to elucidate the protection and mechanism underlying triptolide treatment on astrocytes exposed to hypoxia/reoxygenation injury. The results showed that the matrix metalloproteinase-9, interleukin-1β, tumor necrosis factor α and interleukin-6 expressions were significantly decreased after triptolide treatment in the astrocytes exposed to hypoxia/ reoxygenation injury, while interleukin-10 expression was upregulated. In addition, the vitality of the injured astrocytes was enhanced, the triptolide's effect was apparent at 500 ng/mL. These experimental findings indicate that triptolide treatment could protect astrocytes against hypoxia/ reoxygenation injury through the inhibition of inflammatory response and the reduction of matrix metalloproteinase-9 expression.

    Cisplatin, a commonly used cancer chemotherapeutic, has a dose-limiting side effect of nephrotoxicity. Approximately 30% of patients administered cisplatin suffer from kidney injury, and there are limited treatment options for the treatment of cisplatin-induced kidney injury. Suramin, which is Federal Drug Administration-approved for the treatment of trypanosomiasis, improves kidney function after various forms of kidney injury in rodent models. We hypothesized that suramin would attenuate cisplatin-induced kidney injury. Suramin treatment before cisplatin administration reduced cisplatin-induced decreases in kidney function and injury. Furthermore, suramin attenuated cisplatin-induced expression of inflammatory cytokines and chemokines, endoplasmic reticulum stress, and apoptosis in the kidney cortex. Treatment of mice with suramin 24 h after cisplatin also improved kidney function, suggesting that the mechanism of protection is not by inhibition of tubular cisplatin uptake or its metabolism to nephrotoxic species. If suramin is to be used in the context of cancer, then it cannot prevent cisplatin-induced cytotoxicity of cancer cells. Suramin did not alter the dose-response curve of cisplatin in lung adenocarcinoma cells in vitro. In addition, suramin pretreatment of mice harboring lung adenocarcinomas did not alter the initial cytotoxic effects of cisplatin (DNA damage and apoptosis) on tumor cells. These results provide evidence that suramin has potential as a renoprotective agent for the treatment/prevention of cisplatin-induced acute kidney injury and justify future long-term preclinical studies using cotreatment of suramin and cisplatin in mouse models of cancer.

Stretching exercises are regularly included in warm-up and cooling-down exercises; however, contradictory findings have been reported in the literature. Several authors have suggested that stretching has a beneficial effect on injury prevention. In contrast, clinical evidence suggesting that stretching before exercise does not prevent injuries has also been reported. Apparently, no scientifically based prescription for stretching exercises exists and no conclusive statements can be made about the relationship of stretching and athletic injuries. Stretching recommendations are clouded by misconceptions and conflicting research reports. We believe that part of these contradictions can be explained by considering the type of sports activity in which an individual is participating. Sports involving bouncing and jumping activities with a high intensity of stretch-shortening cycles (SSCs) [e.g. soccer and football] require a muscle-tendon unit that is compliant enough to store and release the high amount of elastic energy that benefits performance in such sports. If the participants of these sports have an insufficient compliant muscle-tendon unit, the demands in energy absorption and release may rapidly exceed the capacity of the muscle-tendon unit. This may lead to an increased risk for injury of this structure. Consequently, the rationale for injury prevention in these sports is to increase the compliance of the muscle-tendon unit. Recent studies have shown that stretching programmes can significantly influence the viscosity of the tendon and make it significantly more compliant, and when a sport demands SSCs of high intensity, stretching may be important for injury prevention. This conjecture is in agreement with the available scientific clinical evidence from these types of sports activities. In contrast, when the type

    Apart from helmets, little is known about the effectiveness of motorcycle protective clothing in reducing injuries in crashes. The study aimed to quantify the association between usage of motorcycle clothing and injury in crashes. Cross-sectional analytic study. Crashed motorcyclists (n=212, 71% of identified eligible cases) were recruited through hospitals and motorcycle repair services. Data was obtained through structured face-to-face interviews. The main outcome was hospitalization and motorcycle crash-related injury. Poisson regression was used to estimate relative risk (RR) and 95% confidence intervals for injury adjusting for potential confounders. Motorcyclists were significantly less likely to be admitted to hospital if they crashed wearing motorcycle jackets (RR=0.79, 95% CI: 0.69-0.91), pants (RR=0.49, 95% CI: 0.25-0.94), or gloves (RR=0.41, 95% CI: 0.26-0.66). When garments included fitted body armour there was a significantly reduced risk of injury to the upper body (RR=0.77, 95% CI: 0.66-0.89), hands and wrists (RR=0.55, 95% CI: 0.38-0.81), legs (RR=0.60, 95% CI: 0.40-0.90), feet and ankles (RR=0.54, 95% CI: 0.35-0.83). Non-motorcycle boots were also associated with a reduced risk of injury compared to shoes or joggers (RR=0.46, 95% CI: 0.28-0.75). No association between use of body armour and risk of fracture injuries was detected. A substantial proportion of motorcycle designed gloves (25.7%), jackets (29.7%) and pants (28.1%) were assessed to have failed due to material damage in the crash. Motorcycle protective clothing is associated with reduced risk and severity of crash related injury and hospitalization, particularly when fitted with body armour. The proportion of clothing items that failed under crash conditions indicates a need for improved quality control. While mandating usage of protective clothing is not recommended, consideration could be given to providing incentives for usage of protective clothing, such as tax exemptions for safety

  14. National programme for prevention of burn injuries

    2010-10-01

    Full Text Available The estimated annual burn incidence in India is approximately 6-7 million per year. The high incidence is attributed to illiteracy, poverty and low level safety consciousness in the population. The situation becomes further grim due to the absence of organized burn care at primary and secondary health care level. But the silver lining is that 90% of burn injuries are preventable. An initiative at national level is need of the hour to reduce incidence so as to galvanize the available resources for more effective and standardized treatment delivery. The National Programme for Prevention of Burn Injuries is the endeavor in this line. The goal of National programme for prevention of burn injuries (NPPBI would be to ensure prevention and capacity building of infrastructure and manpower at all levels of health care delivery system in order to reduce incidence, provide timely and adequate treatment to burn patients to reduce mortality, complications and provide effective rehabilitation to the survivors. Another objective of the programme will be to establish a central burn registry. The programme will be launched in the current Five Year Plan in Medical colleges and their adjoining district hospitals in few states. Subsequently, in the next five year plan it will be rolled out in all the medical colleges and districts hospitals of the country so that burn care is provided as close to the site of accident as possible and patients need not to travel to big cities for burn care. The programme would essentially have three components i.e. Preventive programme, Burn injury management programme and Burn injury rehabilitation programme.

    Motorcycle crash victims form a high proportion of those killed or injured in road traffic crashes. Injuries to the head, following motorcycle crashes, are a common cause of severe morbidity and mortality. It seems intuitive that helmets should protect against head injuries but it has been argued that motorcycle helmet use decreases rider vision and increases neck injuries. This review will collate the current available evidence on helmets and their impact on mortality, and head, face and neck injuries following motorcycle crashes. To assess the effects of wearing a motorcycle helmet in reducing mortality and head and neck injury following motorcycle crashes. We searched the Cochrane Injuries Group Specialised Register, Cochrane Central Register of Controlled Trials (The Cochrane Library issue 2, 2007), MEDLINE (up to April 2007), EMBASE (up to April week 16, 2007), CINAHL (January 1982 to February 2003), TRANSPORT (up to issue 12, 2006) (TRANSPORT combines the following databases: Transportation Research Information Services (TRIS) International Transport Research Documentation (ITRD) formerly International Road Research Documentation (IRRD), ATRI (Australian Transport Index) (1976 to Feb 2003), Science Citation Index were searched for relevant articles. Websites of traffic and road safety research bodies including government agencies were also searched. Reference lists from topic reviews, identified studies and bibliographies were examined for relevant articles. We considered studies that investigated a population of motorcycle riders who had crashed, examining helmet use as an intervention and with outcomes that included one or more of the following: death, head, neck or facial injury. We included any studies that compared an intervention and control group. Therefore the following study designs were included: randomised controlled trials, non-randomised controlled trials, cohort, case-control and cross-sectional studies. Ecological and case series studies were

    2016-01-01

    Many aspects of perinatal nursing put nurses at risk for injuries, including frequent repetitive bending, lifting of clients, and exposure to potentially large amounts of body fluids such as blood and amniotic fluid. Violence is also a potential risk with stressful family situations that may arise around childbirth. Workplace injuries put a health care facility at risk for staff turnover, decreases in the number of skilled nurses, client dissatisfaction, workers' compensation payouts, and employee lawsuits. Through the use of safety equipment, improved safety and violence training programs, "no manual lift" policies, reinforcement of personal protective equipment usage, and diligent staff training to improve awareness, these risks can be minimized.

    The aim of this paper was to assess the incidence of injuries in the general population caused by participation in the sport of target archery or bowhunting. Descriptive analysis of a national probability sample of hospital based treatments for archery-related injuries, over a 10-year period. The leading injuries were lacerations (62±2%), which most often occurred through mishandling hunting arrows. Puncture wounds accounted for 8±1% and foreign bodies 6±1%, arising from feathers or vanes embedding in the hand, falling onto an arrow, or a rupturing arrow shaft. Contusions and abrasions, often caused by the bowstring hitting the arm, accounted for 6±1% of injuries. Nearly all (99±0.4%) of cases were treated and released. The overall injury rate is 4.4/10000 participants age 6 and over. Contrary to the prevailing perception that archery is inherently dangerous, the evidence shows that recreational archery is a very safe sport ‑ safer than popular field sports where people risk collisions or falls, such as soccer, basketball or baseball. The injury rate from lacerations could be significantly reduced if bow hunter education courses emphasized safe handling of broadhead arrows. The data suggest that nearly all acute injuries in target archery can be prevented through participation in an accredited training program and the use of basic protective gear (arm guards and shooting gloves). All archery education programs should focus on proper archery stance and joint strengthening to minimize chronic shoulder and back injuries.

    The human tibial nerves is less prone to injury following joint arthroplasty compared with the peroneal nerves. Besides the anatomical distribution, other features may confer protection from stretch injury. We therefore examined the size, shape and connective tissue distribution for the two nerves. The tibial and peroneal nerves from each side of nine fresh human cadavers we reharvested mid-thigh. Proximal segments manually stretched 20%-25% were fixed in aldehyde, while the adjacent distal segments were fixed in their natural length. Paraffin sections stained by Masson's trichrome method for connective tissue were examined by light microscopy. Tibial nerves had 2X more fascicles compared with the peroneal, but the axonal content appeared similar. Analysis showed that neither nerve had a significant reduction in cross sectional area of the fascicles following stretch. However, fascicles from stretched tibial nerves become significantly more oval compared with those from unstretched controls and peroneal nerves. Tibial nerves had a greater proportion that was extrafascicular tissue (50-55%) compared with peroneal nerves (38%-42%). This epineurium was typically adipose tissue. Perineurial thickness in both nerves was directly related to fascicular size. Tibial nerves have several unique histological features associated with size, shape and tissue composition compared with the peroneal nerve. We suggest that more fascicles with their tightly bound perineurium and more robust epineurium afford protection against stretch injury. Mechanical studies should clarify how size and shape contribute to nerve protection and/or neurapraxia.

    Schnitzer, Patricia G; Covington, Theresa M; Kruse, Robin L

    2011-02-01

    Most unintentional injury deaths among young children result from inadequate supervision or failure by caregivers to protect the child from potential hazards. Determining whether inadequate supervision or failure to protect could be classified as child neglect is a component of child death review (CDR) in most states. However, establishing that an unintentional injury death was neglect related can be challenging as differing definitions, lack of standards regarding supervision, and changing norms make consensus difficult. The purpose of this study was to assess CDR team members' categorisation of the extent to which unintentional injury deaths were neglect related. CDR team members were surveyed and asked to classify 20 vignettes-presented in 10 pairs-that described the circumstances of unintentional injury deaths among children. Vignette pairs differed by an attribute that might affect classification, such as poverty or intent. Categories for classifying vignettes were: (1) caregiver not responsible/not neglect related; (2) some caregiver responsibility/somewhat neglect related; (3) caregiver responsible /definitely neglect related. CDR team members from five states (287) completed surveys. Respondents assigned the child's caregiver at least some responsibility for the death in 18 vignettes (90%). A majority of respondents classified the caregiver as definitely responsible for the child's death in eight vignettes (40%). This study documents attributes that influence CDR team members' decisions when assessing caregiver responsibility in unintentional injury deaths, including supervision, intent, failure to use safety devices, and a pattern of previous neglectful behaviour. The findings offer insight for incorporating injury prevention into CDR more effectively.

  2. Mangafodipir protects against hepatic ischemia-reperfusion injury in mice.

    Directory of Open Access Journals (Sweden)

    Romain Coriat

    Full Text Available INTRODUCTION AND AIM: Mangafodipir is a contrast agent used in magnetic resonance imaging that concentrates in the liver and displays pleiotropic antioxidant properties. Since reactive oxygen species are involved in ischemia-reperfusion damages, we hypothesized that the use of mangafodipir could prevent liver lesions in a mouse model of hepatic ischemia reperfusion injury. Mangafodipir (MnDPDP was compared to ischemic preconditioning and intermittent inflow occlusion for the prevention of hepatic ischemia-reperfusion injury in the mouse. METHODS: Mice were subjected to 70% hepatic ischemia (continuous ischemia for 90 min. Thirty minutes before the ischemic period, either mangafodipir (10 mg/kg or saline was injected intraperitoneally. Those experimental groups were compared with one group of mice preconditioned by 10 minutes' ischemia followed by 15 minutes' reperfusion, and one group with intermittent inflow occlusion. Hepatic ischemia-reperfusion injury was evaluated by measurement of serum levels of aspartate aminotransferase (ASAT activity, histologic analysis of the livers, and determination of hepatocyte apoptosis (cytochrome c release, caspase 3 activity. The effect of mangafodipir on the survival rate of mice was studied in a model of total hepatic ischemia. RESULTS: Mangafodipir prevented experimental hepatic ischemia-reperfusion injuries in the mouse as indicated by a reduction in serum ASAT activity (P<0.01, in liver tissue damages, in markers of apoptosis (P<0.01, and by higher rates of survival in treated than in untreated animals (P<0.001. The level of protection by mangafodipir was similar to that observed following intermittent inflow occlusion and higher than after ischemic preconditioning. CONCLUSIONS: Mangafodipir is a potential new preventive treatment for hepatic ischemia-reperfusion injury.

    1999-12-01

    Modern technology has produced automotive vehicles that have become both a luxury and a necessity in modern civilization. They have become highly useful, even more varied in form and function, and capable of high speeds on crowded roadways. One unfortunate consequence is the high frequency of accidents and the greater severity of injuries when collisions do occur. In response, modern technology has produced a variety of safety and health features, devices and designs intended for better occupant protection on in high speed vehicles. Injury reduction has become a prime design objective, but there are residual risks, which, as technology evolves, require effective communication to those risk. There can be little risk avoidance behavior without awareness of the hazards and effective communication to the vehicle occupant, as to what could and should be done for self-protection. For example, one out of three drivers apparently fails to understand the function of head restraints, few understand the 'safe zone' posture required for air bags and many believe safety features should be adjusted only for comfort. Some of the current residual injury producing problems in occupant systems are specifically described here in order to illustrate what is needed in terms of both design remedies and health promotion activities.

    This study was designed to determine the possible protective effect of captopril treatment against oxidative damage in heart and lung tissues induced by burn injury. Under ether anesthesia, the shaved dorsum of Wistar albino rats was exposed to 90°C water bath for 10 seconds. Captopril was administered intraperitoneally (10 mg/kg) after the burn injury and repeated twice daily. In the sham group, the dorsum was dipped in a 25°C water bath for 10 seconds. At the end of the 24 hours, echocardiographic recordings were performed, then animals were decapitated and heart and lung tissue samples were taken for the determination of tumor necrosis factor-α (TNF-α) as a pro-inflammatory cytokine, malondialdehyde and glutathione levels and myeloperoxidase, caspase-3, and Na+,K+-ATPase activity in addition to the histological analysis. Burn injury caused significant alterations in left ventricular function. In heart and lung tissues, TNF-α and malondialdehyde levels and myeloperoxidase and caspase-3 activities were found to be increased, while glutathione levels and Na+, K+-ATPase activity were decreased due to burn injury. Captopril treatment significantly elevated the reduced glutathione level and Na+, K+-ATPase activity, and decreased cytokine and malondialdehyde levels and myeloperoxidase and caspase-3 activities. Captopril prevents burn-induced damage in heart and lung tissues and protects against oxidative organ damage.

  6. Behaviour, the key factor for sports injury prevention.

    Safety in sports and physical activity is an important prerequisite for continuing participation in sports, as well as for maintenance of a healthy physically active lifestyle. For this reason, prevention, reduction and control of sports injuries are important goals for society as a whole. Recent advances in sports medicine discuss the need for research on real-life injury prevention. Such views call for a more behavioural approach when it comes to actual sports injury prevention. Nevertheless, the role of behaviour in sports injury prevention remains under-researched. In order to push the field of sports injury prevention forward, this article provides an overview of the relationship between behaviour and sports injury risk. Different types of behaviour relate to injury risk factors and injury mechanisms. Behaviour that influences risk factors and injury mechanisms is not confined only to the athlete. Various types of behaviour by, for example, the coach, referee, physical therapist or sports associations, also influence risk factors and injury mechanisms. In addition, multiple behaviours often act together. Some types of behaviour may directly affect injury risk and are by definition a risk factor. Other behaviours may only affect risk factors and injury mechanisms, and influence injury risk indirectly. Recent ideas on injury prevention that call for studies on real-life injury prevention still rely heavily on preventive measures that are established through efficacy research. A serious limitation in such an approach is that one expects that proven preventive measures will be adopted if the determinants and influences of sports safety behaviours are understood. Therefore, if one truly wants to prevent sports injuries in a real-life situation, a broader research focus is needed. In trying to do so, we need to look at lessons learned from other fields of injury prevention research.

    To understand the incidence of violence injury and its prevention in China, and provide reference for the prevention and control of violence injury. The violence injury data in China were collected from national death surveillance data set (2006-2013) and national injury surveillance system (2013) for the descriptive epidemiological analysis on the incidence of violence injury and related death. The laws and policies about violence injury prevention, related data collection capacity and violence injury prevention programs in China were described. The violence injury mortality declined by 46.3% during 2006-2013 from 1.21/100000 to 0.65/100000. The incidence of violence injury death in males peaked in age group 30-34 years (1.42/100000), and it was low in age groupviolence injury death were found in females, i.e. 0.84/100000 in infants, 0.72/100000 in age group 30-34 years and 1.18/100000 in age group≥85 years. The laws and policies about violence injury prevention were imperfect, and the data about violence injury were limited. Most prevention programs were limited in scale and duration. The crude and standardized violence injury mortality declined in China during 2006-2013. It is necessary to conduct gender specific prevention strategies and improve the related law and policy development, data collection and prevention service.

    The aim of this study was to evaluate the protective effect of Diospyros lotus L. fruit extract against the hemolytic damage induced by Vicia faba beans extract in both G6PD enzyme-deficient human and rat erythrocyte in vitro and in vivo. In the former model, venous blood samples were obtained from five subjects with known G6PD deficiency and erythrocyte hemolysis induced by Vicia faba L. bean extract was asessed spectrophotometrically in the presence and absence of Diospyros lotus L. fruits extract. In the in vivo model, G6PD-deficient rats (induced by intraperitoneal injection of dehydroepiandrosterone for 35 days) pre-treated with different doses of Diospyros lotus L. (500, 750, 1000, and 1500 mg/kg, p.o for 7 days) were challenged with Vicia faba beans extract and the protective effect of the fruit extract against hemolysis was evaluated as above. The results have shown that Diospyros lotus L. fruits extract has antioxidant activity that may protect against hemolytic damage induced by Vicia faba bean extract in both G6PD-deficient human and rat erythrocytes. The study gives a scientific basis for the efficacy of the fruit extract as used in Iran. The fact that this was shown in human erythrocytes in vitro is significant and provides a rationale for further testing in vivo in G6PD-deficient human populations.

    We investigated the possible protective effects of ellagic acid on rat kidneys exposed to nicotine during the fetal period. Twenty pregnant female rats were divided randomly into four groups: control (C), nicotine (N), ellagic acid (EA) and nicotine + ellagic acid (N + EA). Nicotine and ellagic acid treatments were continued throughout the pregnancies and for 15 days after delivery. On day 15, all neonatal pups were sacrificed and their kidneys were removed for biochemical and histopathological examination. The nicotine treatment significantly decreased body weight, total glutathione (GSH), glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) activities, and increased malondialdehyde (MDA) and nitric oxide (NO) levels in the N group compared to controls. EA treatment ameliorated decreased body weight, GSH, GSH-Px and SOD activities, and increased MDA and NO levels in group N + EA compared to group N (p kidney damage as shown by incomplete development of glomeruli and Bowman's capsules. Nicotine also caused greater apoptosis in group N compared to group C. Ellagic acid treatment produced histological kidney structure that was closer to normal and it exerted an anti-apoptotic effect in the N + EA group compared to the N group. EA played a protective role against nicotine-induced nephrotoxicity and oxidative stress in rats owing to its antioxidant, radical scavenging and anti-apoptotic effects.

    American flag football is a non-tackle, contact sport with many moderate to severe contact-type injuries reported. A previous prospective injury surveillance study by the authors revealed a high incidence of injuries to the fingers, face, knee, shoulder and ankle. The objectives of the study were to conduct a pilot-prospective injury prevention study in an attempt to significantly reduce the incidence and the severity of injuries as compared to a historical cohort, as well as to provide recommendations for a future prospective injury prevention study. A prospective injury prevention study was conducted involving 724 amateur male (mean age: 20.0 ± 3.1 years) and 114 female (mean age: 21.2 ± 7.2 years) players. Four prevention measures were implemented: the no-pocket rule, self-fitting mouth guards, ankle braces (for those players with recurrent ankle sprains) and an injury treatment information brochure. An injury surveillance questionnaire was administered to record all time-loss injuries sustained in game sessions. There was a statistically significant reduction in the number of injured players, the number of finger/hand injuries, the incidence rate and the incidence proportion between the two cohorts (p injuries can be significantly reduced in flag football. Prevention strategies for a longer, prospective, randomised-controlled injury prevention study should include the strict enforcement of the no-pocket rule, appropriate head gear, the use of comfortable-fitting ankle braces and mouth guards, and changing the blocking rules of the game.

    Full Text Available Global or local ischemia contributes to the pathogenesis of acute kidney injury (AKI. Currently there are no specific therapies to prevent AKI. Potentiation of glycolytic metabolism and attenuation of mitochondrial respiration may decrease cell injury and reduce reactive oxygen species generation from the mitochondria. Meclizine, an over-the-counter anti-nausea and -dizziness drug, was identified in a ‘nutrient-sensitized’ chemical screen. Pretreatment with 100 mg/kg of meclizine, 17 h prior to ischemia protected mice from IRI. Serum creatinine levels at 24 h after IRI were 0.13 ± 0.06 mg/dl (sham, n = 3, 1.59 ± 0.10 mg/dl (vehicle, n = 8 and 0.89 ± 0.11 mg/dl (meclizine, n = 8. Kidney injury was significantly decreased in meclizine treated mice compared with vehicle group (p < 0.001. Protection was also seen when meclizine was administered 24 h prior to ischemia. Meclizine reduced inflammation, mitochondrial oxygen consumption, oxidative stress, mitochondrial fragmentation, and tubular injury. Meclizine preconditioned kidney tubular epithelial cells, exposed to blockade of glycolytic and oxidative metabolism with 2-deoxyglucose and NaCN, had reduced LDH and cytochrome c release. Meclizine upregulated glycolysis in glucose-containing media and reduced cellular ATP levels in galactose-containing media. Meclizine inhibited the Kennedy pathway and caused rapid accumulation of phosphoethanolamine. Phosphoethanolamine recapitulated meclizine-induced protection both in vitro and in vivo.

    The purpose of this multicenter, before-and-after observational study was to determine whether a short educational intervention was associated with improvement in self-reported safety behavior in older adults. We developed 4 original injury prevention presentations with companion testing materials: Motor Vehicle Safety, Fall Prevention, Pedestrian Safety, and Home Safety. Participants also completed pre-post Short Form Health Survey Instrument (SF-12) quality-of-life surveys. Of 414 participants, 226 completed follow-up testing and SF-12 surveys, for a 54.6% response rate. Those who completed either Pedestrian or Home Safety program showed no significant changes (P > .05) in either test scores or SF-12, and they comprised 61.9% of the final sample. Participants in the Motor Vehicle Safety and Fall Prevention programs accounted for 38.1% of the final sample and did show significant improvements between pre-post test scores. Only Fall Prevention participants showed significant differences in pre-post SF-12 scores. In the Fall Prevention group, numerous SF-12 subscores from the initial survey were significantly inversely correlated with pretest scores, and improvements in some SF-12 subscores correlated with improvements in test scores. Findings from the Fall Prevention group suggest that seniors with quality-of-life limitations may be aware of their increased risk and more willing to make changes to enhance safety. Further study is needed because many questions regarding optimal approaches to injury prevention in the aging demographic remain unanswered.

    2012-12-01

    Tornadoes and violent weather pose a hazard to children, yet little is known about the use of personal protective devices during storms. An outbreak of tornadoes on April 27, 2011, resulted in the deaths of 23 children in Alabama. Records from 60 patients seen in a pediatric emergency department for tornado-related injuries were reviewed to identify the use of injury prevention devices. Three children directly exposed to a violent tornado (Enhanced Fujita Scale 4) were using safety equipment, specifically, a helmet and infant car seats. These 3 children sustained only minor injuries. Personal protective devices may have played a role in preventing child injuries from tornadoes. To our knowledge, this is the first report in the medical literature on helmet and infant car seat use as child protective devices during tornadoes.

    Oxidants have been shown to be involved in alcohol-induced liver injury. Moreover, 2-phenyl-1,2-benzisoselenazole-3(2H)-one (ebselen), an organoselenium compound and glutathione peroxidase mimic, decreases oxidative stress and protects against stroke clinically. This study was designed to test the hypothesis that ebselen protects against early alcohol-induced liver injury in rats. Male Wistar rats were fed high-fat liquid diets with or without ethanol (10-16 g/kg/d) continuously for up to 4 weeks using the intragastric enteral feeding protocol developed by Tsukamoto and French. Ebselen (50 mg/kg twice daily, intragastrically) or vehicle (1% tylose) was administered throughout the experiment. Mean urine ethanol concentrations were not significantly different between treatment groups, and ebselen did not affect body weight gains or cyclic patterns of ethanol concentrations in urine. After 4 weeks, serum ALT levels were increased significantly about 4-fold over control values (37 +/- 5 IU/l) by enteral ethanol (112 +/- 7 IU/l); ebselen blunted this increase significantly (61 +/- 8 IU/l). Enteral ethanol also caused severe fatty accumulation, mild inflammation, and necrosis in the liver (pathology score: 4.3 +/- 0.3). In contrast, these pathological changes were blunted significantly by ebselen (pathology score: 2.5 +/- 0.4). While there were no significant effects of either ethanol or ebselen on glutathione peroxidase activity in serum or liver tissue, ebselen blocked the increase in serum nitrate/nitrite caused by ethanol. Furthermore, ethanol increased the activity of NF-kappaB over 5-fold, the number of infiltrating neutrophils 4-fold, and the accumulation of 4-hydroxynonenal over 5-fold. Ebselen blunted all of these effects significantly. These results indicate that ebselen prevents early alcohol-induced liver injury, most likely by preventing oxidative stress, which decreases inflammation.

    Although the overall injury rate in volleyball and beach volleyball is relatively low compared with other team sports, injuries do occur in a discipline specific pattern. Epidemiological research has revealed that volleyball athletes are, in general, at greatest risk of acute ankle injuries and overuse conditions of the knee and shoulder. This structured review discusses both the known and suspected risk factors and potential strategies for preventing the most common volleyball related injuries: ankle sprains, patellar tendinopathy, and shoulder overuse.

    2013-01-01

    Full Text Available Background. The aims of this study were to identify subgroups of motorcyclists with a higher accident risk and evaluate the efficiency of protective clothing for preventing injuries. Methods. A 1-year prospective study of motorcycle crashes was conducted beginning in June 2012. Participants were patients involved in motorcycle crashes and admitted to our emergency department. Results. A total of 226 patients were included in the study. In total, 174 patients were involved in crashes with light motorcycles. Patients involved in a motorcycle accident without a helmet had a higher incidence of head and maxillofacial trauma. Motorcycle jackets were not protective for systemic injuries (P>0.05 or upper extremity fractures (P>0.05. Motorcycle pants (P>0.05 and motorcycle shoes (P>0.05 were not protective against leg and foot fractures. However, motorcycle protective clothes were protective against soft-tissue injuries (P=0.001. Conclusion. Riders of heavy motorcycles rode more safely than riders of light motorcycles. Light motorcycle riders were the most vulnerable and comprised the largest percentage of motorcyclists. Helmets may be effective for preventing head and facial injuries. Other protective clothes were not effective against fractures or systemic injuries.

    To evaluate the protective role of membrane cofactor protein (MCP, CD46) on complement-dependent injury. MCP was separated by ion exchange chromatography on a DEAE sephadex A-50 column from pig erythrocyte ghosts. Its protective effect was tested in models such as cobra venom factor (CVF)-induced platelet metamorphosis and aggregation, human serum-induced injury in isolated working guinea pig heart and reverse passive Arthus reaction. MCP inhibited CVF-induced platelet metamorphosis with an IC50 of 56.7 mg/L+/-2.6 mg/L, and prevented injury induced by activated complement in isolated working guinea pig hearts. In the rat model of reverse Arthus reaction, MCP relieved the skin lesions induced by immune complexes. MCP has a protective effect against complement-dependent injury.

    Since the introduction of head protection, a decrease in sports-related traumatic brain injuries has been reported. The incidence of concussive injury, however, has remained the same or on the rise. These trends suggest that current helmets and helmet standards are not effective in protecting against concussive injuries. This article presents a literature review that describes the discrepancy between how helmets are designed and tested and how concussions occur. Most helmet standards typically use a linear drop system and measure criterion such as head Injury criteria, Gadd Severity Index, and peak linear acceleration based on research involving severe traumatic brain injuries. Concussions in sports occur in a number of different ways that can be categorized into collision, falls, punches, and projectiles. Concussive injuries are linked to strains induced by rotational acceleration. Because helmet standards use a linear drop system simulating fall-type injury events, the majority of injury mechanisms are neglected. In response to the need for protection against concussion, helmet manufacturers have begun to innovate and design helmets using other injury criteria such as rotational acceleration and brain tissue distortion measures via finite-element analysis. In addition to these initiatives, research has been conducted to develop impact protocols that more closely reflect how concussions occur in sports. Future research involves a better understanding of how sports-related concussions occur and identifying variables that best describe them. These variables can be used to guide helmet innovation and helmet standards to improve the quality of helmet protection for concussive injury.

    Injuries are the result of an acute exposure to exhort of energy or a consequence of a deficiency in a vital element that exceeds physiological thresholds resulting threatens life. They are classified as intentional or unintentional. Injuries are considered a global health issue because they cause more than 5 million deaths per year worldwide and they are an important contributor to the burden of disease, especially affecting people of low socioeconomic status in low- and middle-income countries. A common misconception exists where injuries are thought to be the same as accidents; however, accidents are largely used as chance events, without taken in consideration that all these are preventable. This review discusses injuries and accidents in the context of road traffic and emphasizes injuries as preventable events. An understanding of the essence of injuries enables the standardization of terminology in public use and facilitates the development of a culture of prevention among all of us.

  20. Barriers and Enablers to Enacting Child and Youth Related Injury Prevention Legislation in Canada

    2016-07-01

    Full Text Available Injury prevention policy is crucial for the safety of Canada’s children; however legislation is not adopted uniformly across the country. This study aimed to identify key barriers and enablers to enacting injury prevention legislation. Purposive snowball sampling identified individuals involved in injury prevention throughout Canada. An online survey asked respondents to identify policies that were relevant to them, and whether legislation existed in their province. Respondents rated the importance of barriers or enablers using a 5-point Likert type scale and included open-ended comments. Fifty-seven respondents identified the most common injury topics: bicycle helmets (44, 77%, cell phone-distracted driving (36, 63%, booster seats (28, 49%, ski helmets (24, 42%, and graduated driver’s licensing (21, 37%. The top enablers were research/surveillance, managerial/political support and professional group consultation, with much variability between injury topics. Open-ended comments emphasized the importance of a united opinion as an enabler and barriers included costs of protective equipment and inadequate enforcement of legislation. The results highlighted the importance of strategies that include research, management and community collaboration and that injury prevention topics should be addressed individually as information may be lost if topics are considered together. Findings can inform the process of turning injury prevention evidence into action.

    1995-01-01

    The Harlem Hospital Injury Prevention Program (HHIPP) was established in 1988 with the goal of reducing injuries to children in central Harlem by providing safe play areas, supervised activities, and injury prevention education. To achieve this goal, a broad-based coalition was formed with state and local governmental agencies interested in injury prevention and with community groups, schools, parents, and hospital staff. An evaluation of the program in terms of both process and outcome formed a critical element of this effort. Since 1988 the HHIPP, as the lead agency for the Healthy Neighborhoods/Safe Kids Coalition, developed or participated in two types of programs: injury-prevention education programs and programs that provide safe activities and/or environments for children. The educational programs included Window Guards campaign; Safety City Program; Kids, Injuries and Street Smarts Program (KISS); Burn Prevention Curriculum and Smoke Detector Distribution; Harlem Alternative to Violence Program; Adolescent Outreach Program; and Critical Incident Stress Management Teams. The safe activities and environmental programs included the Bicycle Safety Program/Urban Youth Bike Corps; Playground Injury Prevention Program; the Greening of Harlem Program; the Harlem Horizon Art Studio; Harlem Hospital Dance Clinic; Unity through Murals project; baseball at the Harlem Little League; winter baseball clinic; and the soccer league. Each program was conceived using injury data, coupled with parental concern and activism, which acted as catalysts to create a community coalition to respond to a specific problem. Data systems developed over time, which monitored the prevalence and incidence of childhood injuries in northern Manhattan, including central Harlem, became essential not only to identify specific types of childhood injuries in this community but also to evaluate these programs for the prevention of injuries in children.

  2. NRF2 Protection against Liver Injury Produced by Various Hepatotoxicants

    Full Text Available To investigate the role of Nrf2 as a master defense against the hepatotoxicity produced by various chemicals, Nrf2-null, wild-type, Keap1-knock down (Keap1-Kd and Keap1-hepatocyte knockout (Keap1-HKO mice were used as a “graded Nrf2 activation” model. Mice were treated with 14 hepatotoxicants at appropriate doses, and blood and liver samples were collected thereafter (6 h to 7 days depending on the hepatotoxicant. Graded activation of Nrf2 offered a Nrf2-dependent protection against the hepatotoxicity produced by carbon tetrachloride, acetaminophen, microcystin, phalloidin, furosemide, cadmium, and lithocholic acid, as evidenced by serum alanine aminotransferase (ALT activities and by histopathology. Nrf2 activation also offered moderate protection against liver injury produced by ethanol, arsenic, bromobenzene, and allyl alcohol but had no effects on the hepatotoxicity produced by D-galactosamine/endotoxin and the Fas ligand antibody Jo-2. Graded Nrf2 activation reduced the expression of inflammatory genes (MIP-2, mKC, IL-1β, IL-6, and TNFα, oxidative stress genes (Ho-1, Egr1, ER stress genes (Gadd45 and Gadd153, and genes encoding cell death (Noxa, Bax, Bad, and caspase3. Thus, this study demonstrates that Nrf2 prevents the liver from many, but not all, hepatotoxicants. The Nrf2-mediated protection is accompanied by induction of antioxidant genes, suppression of inflammatory responses, and attenuation of oxidative stress.

    Acetaminophen (APAP) overdose accounts for half of the cases of acute liver failure worldwide. We previously reported that Sestrin2 (Sesn2) protects against d-galactosamine/lipopolysaccharide-induced acute fulminant liver failure. In this study, we demonstrated that Sesn2 protects APAP-induced liver injury in mice, using a recombinant adenovirus encoding Sesn2 (Ad-Sesn2). First, we found that treatment of mice with toxic levels of APAP significantly reduced Sesn2 expression. Tail-vein injection with Ad-Sesn2 inhibited APAP-induced serum alanine aminotransferase and aspartate aminotransferase levels and markedly reduced hepatocyte degeneration and inflammatory cell infiltration. Additionally, APAP-induced glutathione depletion and reactive oxygen species generation were inhibited by Ad-Sesn2 treatment. Consistently, hepatic inflammatory gene expression and proinflammatory cytokine levels were also inhibited in Sesn2-infected mice, and we observed reduced APAP-mediated apoptotic signaling by terminal transferase-mediated dUTP nick-end labeling staining of the hepatic tissue. At a high dose of APAP, the mortality rate of Ad-Sesn2-infected mice was significantly lower than that of control mice. Furthermore, Sesn2 prevented APAP-induced damage through suppression of downstream mitogen-activated protein kinase pathway activation. Therefore, Sesn2 exerted a protective effect against APAP-induced acute liver damage by inhibiting oxidative stress and proinflammatory signaling. Copyright © 2017 Elsevier B.V. All rights reserved.

    Physical Education Teacher Education (PETE) students are at considerable risk for non-contact sports injuries of the lower extremities. Multifactorial injury prevention interventions including exercises have been successful in sports populations, but no such study has ever been performed in PETE students. This study investigated the efficacy of a multifactorial injury prevention intervention on injury incidence reduction in PETE students. PETE students in the intervention group (n = 154) and in the control group (n = 189) registered sports injuries prospectively. The intervention lasted one academic year and consisted of an injury awareness programme and preventive strategies, implemented by the PETE sports lecturers. Differences in injury incidence between the intervention and control group were tested by Poisson regression Wald tests. There was a trend towards significantly lower incidence rate (2.18 vs. 2.73; p = 0.061) in the intervention group compared with the control group. Students in the intervention group had significantly less acute, first-time and extracurricular injuries. The largest reduction was observed for injuries during unsupervised practice sessions. A multifactorial injury prevention intervention embedded into a regular PETE programme is a promising and feasible strategy to prevent injuries in PETE students. Further research is needed to investigate whether the results may be generalised to other PETE programmes.

    Several lines of evidence suggest that, besides being a strong independent predictor of the occurrence of primary coronary events, a low plasma high density lipoprotein (HDL) cholesterol level is also associated with short- and long-term unfavorable prognosis in patients, who have recovered from a myocardial infarction, suggesting a direct detrimental effect of low HDL on post-ischemic myocardial function. Experiments performed in ex vivo and in vivo models of myocardial ischemia/reperfusion (I/R) injury have clearly shown that HDL are able to preserve cardiac function when given before ischemia or at reperfusion; the protective effects of HDL against I/R injury have been also confirmed in other tissues and organs, as brain and hind limb. HDL were shown to act on coronary endothelial cells, by limiting the increase of endothelium permeability and promoting vasodilation and neoangiogenesis, on white blood cells, by reducing their infiltration into the ischemic tissue and the release of pro-inflammatory and matrix-degrading molecules, and on cardiomyocytes, by preventing the activation of the apoptotic cascade. Synthetic HDL retains the cardioprotective activity of plasma-derived HDL and may become a useful adjunctive therapy to improve clinical outcomes in patients with acute coronary syndromes or undergoing coronary procedures.

    The air bag, like the seatbelt, is a further development of the inside protection of motorcar passengers. However, the airbag has also been made responsible for severe internal injuries. In a retrospective case control study, 394 accidents in which the air bag was released were analysed. At least medium severe injuries (Maximum Abbreviated Injury Scale: MAIS > or = 2) occurred in 69 cases. Three different patterns of injury were distinguished depending on the level of difficulty of diagnosis by the emergency physician. Damage to the vehicles was scored in five intensities or damage grades. Thoracic injury was most frequently diagnosed in the patients (in 61.5 % of cases), followed by injuries to the lower (50.8 %) and upper extremities (47.7 %). Single injuries with a grade of severity of 2 (MAIS) predominated (59.7 %). In most of the cases the injury was easy to diagnose (64.6 %) because of external signs, in 24.6 % internal injuries were assumed and in only 10.8 % were there no sings of damage to body cavities. Most frequent were occult injuries in the thoracic region (100 %) and in the abdomen (74.4 %). However, occult injuries did not always conform to the grade of deformation to the vehicle, since in 66.7 % the grade of damage was 3. This was not true for the remaining types of injury because external injuries increased with the grade of damage to the vehicle. After the release of the air bag, occult injuries of the body cavities have to be expected, even if there are no signs of external injury. Women under 35 years of age are particularly endangered. There exists no minimum velocity for the occurrence of injuries to the body cavities because harm can simply be a result of the release of the air bag.

  16. Resistance Training in Youth: Laying the Foundation for Injury Prevention and Physical Literacy.

    Zwolski, Christin; Quatman-Yates, Catherine; Paterno, Mark V

    The rising incidence of physical activity- and sports-related injuries has prompted the present-day investigation of resistance training as a potential means of injury prevention and physical literacy development among youth. Relevant studies on the topics of athlete development, physical literacy, resistance training, and injury prevention in children and adolescents were reviewed (PubMed and Sports Discus, 1982-2016). Recommendations from consensus guidelines and position statements applicable to resistance training and injury prevention in youth, in addition to young athlete development, were reviewed. Additionally, hand searches, expert requests, article reference lists, and gray literature were utilized and reviewed for pertinent content. Clinical review. Level 4. Youth throughout the physical activity spectrum are at risk for physical activity- and sports-related injury. Of highest priority are early specializers, physically inactive youth, and young girls, owing to increased injury rates. Resistance training among these at-risk populations has been shown to reduce injury risk by up to 68% and improve sports performance and health measures, in addition to accelerating the development of physical literacy. Recent recommendations, position statements, and national initiatives advocate for the incorporation of resistance training with qualified instruction among these groups. Resistance training in addition to free play and other structured physical activity training can serve as a protective means against injury and a positive catalyst for the development of physical literacy to offset the impact of diminishing physical activity and early sport specialization in today's youth.

    Youth have very high participation and injury rates in sport. Sport is the leading cause of injury in youth. Sport injury reduces future participation in physical activity which adversely affects future health. Sport injury may lead to overweight/obesity and post-traumatic osteoarthritis. The objective of the systematic review and meta-analysis was to evaluate the efficacy of injury prevention neuromuscular training strategies in youth sport. Three electronic databases were systematically searched up to September 2014. Studies selected met the following criteria: original data; analytic prospective design; investigated a neuromuscular training prevention strategy intervention(s) and included outcomes for injury sustained during sport participation. Two authors assessed the quality of evidence using Downs and Black (DB) criteria. Meta-analyses including randomised controlled trials only (RCTs) to ensure study design homogeneity were completed for lower extremity and knee injury outcomes. Of 2504 potentially relevant studies, 25 were included. Meta-analysis revealed a combined preventative effect of neuromuscular training in reducing the risk of lower extremity injury (incidence rate ratio: IRR=0.64 (95% CI 0.49 to 0.84)). Though not statistically significant, the point estimate suggests a protective effect of such programmes in reducing the risk of knee injury (IRR=0.74 (95% CI 0.51 to 1.07)). There is evidence for the effectiveness of neuromuscular training strategies in the reduction of injury in numerous team sports. Lack of uptake and ongoing maintenance of such programmes is an ongoing concern. A focus on implementation is critical to influence knowledge, behaviour change and sustainability of evidence informed injury prevention practice. Published by the BMJ Publishing Group Limited.

    McGuine, Tim

    2006-11-01

    The objective of this review is to identify the available research regarding the risk factors and prevention of injuries in high school athletes (ages 14 to 18 years). Relevant manuscripts were identified by searching six electronic databases with a combination of key words and medical subject headings (high school, adolescent, athletic injury, sports injury, risk factors, prevention, and prospective). Original research that reported prospective data on high school athletes (ages 14 to 18), reported injury and exposure data, and used data collected throughout the entire sport season or school year. Twenty-nine studies that identified injury risk factors or injury prevention strategies were reviewed and summarized. Data extracted from the studies included a) sport(s) or injuries studied, b) year of publication, c) lead author, d) description of the subjects, e) sample-size calculation, f) variables studied (baseline demographic or performance variables), g) whether multivariate analyses were used, h) data reported (injury rates, risk ratios, and 95% CI), and i) results. Studies that introduced an intervention were characterized by the same data as well as the type of intervention employed and randomization procedures used. The quality of each injury-risk and injury-prevention study was assessed, and the results were summarized. The risk factors for injury in several specific sports such as soccer, American football, and basketball have been documented. Other sports are less well represented in the current literature. The risk factors for injuries to the ankle, head, and knee have been identified, to a limited degree. Upper-extremity injury risk factors are less well known. There is a need for high-quality prospective studies to further identify injury risk factors and injury-prevention strategies for high school athletes.

    AIM To evaluate the role of intraoperative cholangiogram (IOC) in preventing biliary duct injury duringlaparoscopic cholecystectomy.METHODS Injury location, mechanism, time of detection, treatment outcome, and whether anintraoperative cholangiogram was performed were evaluated in 31 cases of bile duct injuries.RESULTS Cholangiograms were done in 22 cases, but they were misinterpreted in 3 of them. In 12 of 19misidentified cases, the cholangiogram was interpreted correctly, and the injury detected intraoperatively.Primary laparoscopic repair or open repair and T-tube drainage solved the problem. No long-termcomplications occurred. However, in 3 of the 19 cases the cholangiogram was misinterpreted and in 4 of the19 cases no cholangiogram was performed. Three of the seven patients required a cholangioentericanastomosis. In 2 cases the diagnosis was delayed and one of these required a two-stage procedure. Morbiditywas increased. Three cases of clim impingement of the common duct had delayed diagnoses, and two of themhad injuries. Thermal injury developed in 4 cases who had cholangiograms.CONCLUSION Routine IOC plays no role in inducing, preventing, detecting, or minimizing any of theinjuries due to clips, lacerations, or electrocautery, IOC does not prevent injuries due to ductmisidentification either. Careful interpretation of IOC would prevent injuries and avoid an open operation.

  7. Pigment Epithelium Derived Factor Peptide Protects Murine Hepatocytes from Carbon Tetrachloride-Induced Injury.

    Directory of Open Access Journals (Sweden)

    Shou-Chuan Shih

    Full Text Available Fibrogenesis is induced by repeated injury to the liver and reactive regeneration and leads eventually to liver cirrhosis. Pigment epithelium derived factor (PEDF has been shown to prevent liver fibrosis induced by carbon tetrachloride (CCl4. A 44 amino acid domain of PEDF (44-mer was found to have a protective effect against various insults to several cell types. In this study, we investigated the capability of synthetic 44-mer to protect against liver injury in mice and in primary cultured hepatocytes. Acute liver injury, induced by CCl4, was evident from histological changes, such as cell necrosis, inflammation and apoptosis, and a concomitant reduction of glutathione (GSH and GSH redox enzyme activities in the liver. Intraperitoneal injection of the 44-mer into CCl4-treated mice abolished the induction of AST and ALT and markedly reduced histological signs of liver injury. The 44-mer treatment can reduce hepatic oxidative stress as evident from lower levels of lipid hydroperoxide, and higher levels of GSH. CCl4 caused a reduction of Bcl-xL, PEDF and PPARγ, which was markedly restored by the 44-mer treatment. Consequently, the 44-mer suppressed liver fibrosis induced by repeated CCl4 injury. Furthermore, our observations in primary culture of rat hepatocytes showed that PEDF and the 44-mer protected primary rat hepatocytes against apoptosis induced by serum deprivation and TGF-β1. PEDF/44-mer induced cell protective STAT3 phosphorylation. Pharmacological STAT3 inhibition prevented the antiapoptotic action of PEDF/44-mer. Among several PEDF receptor candidates that may be responsible for hepatocyte protection, we demonstrated that PNPLA2 was essential for PEDF/44-mer-mediated STAT3 phosphorylation and antiapoptotic activity by using siRNA to selectively knockdown PNPLA2. In conclusion, the PEDF 44-mer protects hepatocytes from single and repeated CCl4 injury. This protective effect may stem from strengthening the counter oxidative stress

    2007-01-01

    To summarize 16 years of National Collegiate Athletic Association (NCAA) injury surveillance data for 15 sports and to identify potential modifiable risk factors to target for injury prevention initiatives. In 1982, the NCAA began collecting standardized injury and exposure data for collegiate sports through its Injury Surveillance System (ISS). This special issue reviews 182 000 injuries and slightly more than 1 million exposure records captured over a 16-year time period (1988-1989 through 2003-2004). Game and practice injuries that required medical attention and resulted in at least 1 day of time loss were included. An exposure was defined as 1 athlete participating in 1 practice or game and is expressed as an athlete-exposure (A-E). Combining data for all sports, injury rates were statistically significantly higher in games (13.8 injuries per 1000 A-Es) than in practices (4.0 injuries per 1000 A-Es), and preseason practice injury rates (6.6 injuries per 1000 A-Es) were significantly higher than both in-season (2.3 injuries per 1000 A-Es) and postseason (1.4 injuries per 1000 A-Es) practice rates. No significant change in game or practice injury rates was noted over the 16 years. More than 50% of all injuries were to the lower extremity. Ankle ligament sprains were the most common injury over all sports, accounting for 15% of all reported injuries. Rates of concussions and anterior cruciate ligament injuries increased significantly (average annual increases of 7.0% and 1.3%, respectively) over the sample period. These trends may reflect improvements in identification of these injuries, especially for concussion, over time. Football had the highest injury rates for both practices (9.6 injuries per 1000 A-Es) and games (35.9 injuries per 1000 A-Es), whereas men's baseball had the lowest rate in practice (1.9 injuries per 1000 A-Es) and women's softball had the lowest rate in games (4.3 injuries per 1000 A-Es). In general, participation in college athletics is safe

    Giles, Audrey R; Hognestad, Sarah; Brooks, Lauren A

    2015-01-01

    Public health nurses are on the front line of injury prevention initiatives. However, within injury prevention interventions and research, issues pertaining to culture are often addressed through the employment of one of the three approaches: cultural competency, cultural appropriateness, and/or cultural sensitivity. When using these approaches, it is often suggested that it is only those who are the recipients of an intervention or the focus of research that "have" culture. The injury prevention designer's/provider's/researcher's own culture, as well as the ways in which it may influence the interventions or research, is typically rendered invisible. In this paper, we provide an overview and illustrations of the use of cultural competency, cultural appropriateness, and cultural sensitivity in injury prevention initiatives, as well as each approach's shortcomings. We then introduce cultural safety, an approach that has not yet gained traction in injury prevention but has had significant uptake within nursing in general, and argue that it has the potential to overcome many other approaches' shortcomings and thus may lead to more effective and socially just injury prevention initiatives.

    Injuries, one of the leading public health problems in an otherwise healthy military population, affect operational readiness, increase healthcare costs, and result in disabilities and fatalities. This paper describes a systematic, data-driven, injury prevention-decision making process to rank potential injury prevention targets. Medical surveillance and safety report data on injuries for 2004 were reviewed. Nonfatal injury diagnoses (ICD-9-CM codes) obtained from the Defense Medical Surveillance System were ranked according to incident visit frequency and estimated limited duty days. Data on the top five injury types resulting in the greatest estimated limited duty days were matched with hospitalization and Service Safety Centers' accident investigation data to identify leading causes. Experts scored and ranked the causes using predetermined criteria that considered the importance of the problem, preventability, feasibility, timeliness of intervention establishment/results, and ability to evaluate. Department of Defense (DoD) and Service-specific injury prevention priorities were identified. Unintentional injuries lead all other medical conditions for number of medical encounters, individuals affected, and hospital bed days. The top ten injuries resulted in an estimated 25 million days of limited duty. Injury-related musculoskeletal conditions were a leading contributor to days of limited duty. Sports and physical training were the leading cause, followed by falls. A systematic approach to injury prevention-decision making supports the DoD's goal of ensuring a healthy, fit force. The methodology described here advances this capability. Immediate follow-up efforts should employ both medical and safety data sets to identify and monitor injury prevention priorities.

    2005-07-01

    In the coal industry of Ukraine there are 160 operating - state, joint-stock and private - mines producing 80 million tons of coal a year, with 400,000 persons working, including about 200,000 underground. Accident/injury level at mines still remains high owing to difficult mining and geological conditions, low comprehensive mechanization of hard and injury-causing work processes, deficiency of emergency protection systems, considerable turnover of personnel, insufficient qualification and low labour discipline, underestimation of hazards by many workers and management. The conception reflecting ways and methods of achieving the planned goals is developed by the Ministry of Fuel and Energy of Ukraine together with MakNII to seriously improve labour protection, completely prevent disasters, and considerably decrease injuries and occupational diseases at mines. Implementation of the Conception will allow to considerably decrease accident and injury rates at the coal mines of Ukraine. 12 refs.

    Context Anterior cruciate ligament (ACL) injury is a major concern in physically active females. Although ACL reconstruction techniques have seen significant advances in recent years, risk associated with re-injury and future osteoarthritis remains a major concern. Thus, prevention of ACL injury is a logical step to protect and preserve healthy knee joints in young athletes. The current report aims to summarize a list of evidence-based prevention strategies to reduce ACL injury in female athletes. A list of six critical principles, which come from documented, large scale clinical trial studies and further analyses, were presented with ABC format including age, biomechanics, compliance, dosage, exercise, and feedback. Also, a grade for evidence and implications of future research is noted. Finally, in the conclusion section, importance of collaborative efforts from healthcare practitioners, researchers, and personnel associated with athletics is addressed. PMID:26042191

  16. Strategies to prevent intraoperative lung injury during cardiopulmonary bypass

    Directory of Open Access Journals (Sweden)

    Siminelakis Stavros N

    2010-01-01

    Full Text Available Abstract During open heart surgery the influence of a series of factors such as cardiopulmonary bypass (CPB, hypothermia, operation and anaesthesia, as well as medication and transfusion can cause a diffuse trauma in the lungs. This injury leads mostly to a postoperative interstitial pulmonary oedema and abnormal gas exchange. Substantial improvements in all of the above mentioned factors may lead to a better lung function postoperatively. By avoiding CPB, reducing its time, or by minimizing the extracorporeal surface area with the use of miniaturized circuits of CPB, beneficial effects on lung function are reported. In addition, replacement of circuit surface with biocompatible surfaces like heparin-coated, and material-independent sources of blood activation, a better postoperative lung function is observed. Meticulous myocardial protection by using hypothermia and cardioplegia methods during ischemia and reperfusion remain one of the cornerstones of postoperative lung function. The partial restoration of pulmonary artery perfusion during CPB possibly contributes to prevent pulmonary ischemia and lung dysfunction. Using medication such as corticosteroids and aprotinin, which protect the lungs during CPB, and leukocyte depletion filters for operations expected to exceed 90 minutes in CPB-time appear to be protective against the toxic impact of CPB in the lungs. The newer methods of ultrafiltration used to scavenge pro-inflammatory factors seem to be protective for the lung function. In a similar way, reducing the use of cardiotomy suction device, as well as the contact-time between free blood and pericardium, it is expected that the postoperative lung function will be improved.

    2015-11-01

    Nerve injuries can cause substantial morbidity after thoracic surgical procedures. These injuries are preventable, provided that the surgeon has a thorough understanding of the anatomy and follows important surgical principles. When nerve injuries occur, it is important to recognize the options available in the immediate and postoperative settings, including expectant management, immediate nerve reconstruction, or auxiliary procedures. This article covers the basic anatomy and physiology of nerves and nerve injuries, an overview of techniques in nerve reconstruction, and a guide to the nerves most commonly involved in thoracic operative procedures.

  18. Preventing unintentional injury in children and adolescents--the importance of local injury data collection.

    O'Carroll, C

    2012-02-01

    We sought to prospectively study all injuries in children and adolescents up to 16 years of age presenting to a regional Emergency Department (ED), to ascertain detailed injury patterns and to use this data to recommend injury prevention priorities. Electronic injury surveillance was prospectively collected over a 10 year period (1997-2007) in a hospital with a paediatric catchment population of 75,000 in a region with pockets of high social deprivation. All fatalities were obtained from data provided by the Central Statistics Office (CSO). Over a 10 year period, there were 31 fatalities, 5,408 admissions and 40,817 new attendances due to injury. Males outnumbered females in a 3:2 ratio. Of all injuries 24,317 (60%) occurred at home. Peak injury presentation time was in the evening between 18:00 and 20:00. Minor injuries (bruises, minor head injuries, lacerations and sprains) accounted for 32,456 (80%) of total. Fractures resulting from high falls (n=1,194) tended to result from bunk beds, staircases, horses, walls and playground equipment. Burns (n=630) involved hot liquids (tea, coffee), hot bath water, hot cooking oil and hot cooking plates. Pedestrian injuries (n=251) were predominantly \\'dart outs\\' in urban areas. Car passenger injuries (n=869) showed low rates of documented car restraint use. Poisonings (n= 1,153) were predominantly medicinal products. Cyclist injuries (n=477) indicated low documented use of appropriate helmet wear. Prevention priorities should focus on home injuries, hot liquid burn and scald injuries and high falls from walls, beds and playground equipment. To prevent road-related injuries and deaths, further legislation, urban planning and greater police enforcement is required.

  19. Preventive Effects of Safety Helmets on Traumatic Brain Injury after Work-Related Falls

    2016-10-01

    Full Text Available Introduction: Work-related traumatic brain injury (TBI caused by falls is a catastrophic event that leads to disabilities and high socio-medical costs. This study aimed to measure the magnitude of the preventive effect of safety helmets on clinical outcomes and to compare the effect across different heights of fall. Methods: We collected a nationwide, prospective database of work-related injury patients who visited the 10 emergency departments between July 2010 and October 2012. All of the adult patients who experienced work-related fall injuries were eligible, excluding cases with unknown safety helmet use and height of fall. Primary and secondary endpoints were intracranial injury and in-hospital mortality. We calculated adjusted odds ratios (AORs of safety helmet use and height of fall for study outcomes, and adjusted for any potential confounders. Results: A total of 1298 patients who suffered from work-related fall injuries were enrolled. The industrial or construction area was the most common place of fall injury occurrence, and 45.0% were wearing safety helmets at the time of fall injuries. The safety helmet group was less likely to have intracranial injury comparing with the no safety helmet group (the adjusted odds ratios (ORs (95% confidence interval (CI: 0.42 (0.24–0.73, however, there was no statistical difference of in-hospital mortality between two groups (the adjusted ORs (95% CI: 0.83 (0.34–2.03. In the interaction analysis, preventive effects of safety helmet on intracranial injury were significant within 4 m height of fall. Conclusions: A safety helmet is associated with prevention of intracranial injury resulting from work-related fall and the effect is preserved within 4 m height of fall. Therefore, wearing a safety helmet can be an intervention for protecting fall-related intracranial injury in the workplace.

    Full Text Available This is a study of the theoretical optimal (limiting performance of helmets for the prevention of head injury. A rigid head injury model and a two-mass translational head injury model are employed. Several head injury criteria are utilized, including head acceleration, the head injury criterion (HIC, the energy imparted to the brain which is related to brain injury, and the power developed in the skull that is associated with skull fracture. A helmeted head hitting a rigid surface and a helmeted head hit by a moving object such as a ball are considered. The optimal characteristics of helmets and the impact responses of the helmeted head are investigated computationally. An experiment is conducted on an ensemble of bicycle helmets. Computational results are compared with the experimental results.

    Objective: To provide athletic trainers, health care professionals, and all those responsible for the care of athletes with clinical recommendations for preventing and managing sport-related dental and oral injuries. Background: Participation in competitive sports continues to grow at both the interscholastic and intercollegiate levels. Therefore, exposure to, and the incidence of athletic-related injury, including orofacial injury, will also likely increase. At the time of this writing, the leading governing agencies for interscholastic (National Federation of State High School Associations) and intercollegiate (National Collegiate Athletic Association) sports require only protective orofacial equipment (eg, mouthguards) for 5 and 4, respectively, of their sanctioned sports. Although orofacial injuries represent a small percentage of all sport-related injuries, the financial burden associated with these injuries (eg, tooth avulsion) can exceed $15 000 over an adult life. Therefore, effective management of sport-related dental injuries is critical to the long-term financial, physical, and emotional health of people who have experienced dental trauma. Recommendations: Based upon the current evidence regarding sport-related orofacial injury, we provide recommendations related to planning considerations, education, and mouthguard efficacy, material, fabrication, and care considerations. Additionally, suggested best practices for managing sport-related dental injury are also given for athletic trainers and other health care professionals. PMID:27875057

    High levels of youth employment, workplace hazards, and characteristics unique to adolescents contribute to a relatively high incidence of injuries among teens in the restaurant industry. This article discusses the ProSafety model of injury prevention among teen restaurant workers. Through integration with an existing career and technical education program, the ProSafety project seeks to prevent occupational injuries among the teen worker population through classroom safety education and internship skills reinforcement. ProSafety is the product of an innovative collaboration with occupational health nurses, business professionals, educators, and government. Its approach is derived from Social Cognitive Theory, is consistent with key values and strategies of occupational health nurses, and provides lessons for practitioners seeking to reduce occupational injuries in food service or among other populations of adolescent workers.

    1994-12-01

    Rugby league is the main professional team sport played in Eastern Australia. It is also very popular at a junior and amateur level. However, injuries are common because of the amount of body contact that occurs and the amount of running that is required to participate in the game. Injuries to the lower limbs account for over 50% of all injuries. The most common specific injuries are ankle lateral ligament tears, knee medial collateral and anterior cruciate ligament tears, groin musculotendinous tears, hamstring and calf muscle tears, and quadriceps muscle contusions. Head injuries are common and consist of varying degrees of concussion as well as lacerations and facial fractures. Serious head injury is rare. Some of the more common upper limb injuries are to the acromioclavicular and glenohumeral joints. Accurate diagnosis of these common injuries using appropriate history, examination and investigations is critical in organising a treatment and rehabilitation plan that will return the player to competition as soon as possible. An understanding of the mechanism of injury is also important in order to develop preventative strategies.

    Injury to the facial nerve during a face lift is a relatively rare but serious complication. A large body of literature has been dedicated toward bettering the understanding of the anatomical course of the facial nerve and the relative danger zones. Most of these prior reports, however, have focused on identifying the location of facial nerve branches based on their trajectory mostly in two dimensions and rarely in three dimensions. Unfortunately, the exact location of the facial nerve relative to palpable or visible facial landmarks is quite variable. Although the precise location of facial nerve branches is variable, its relationship to soft-tissue planes is relatively constant. The focus of this report is to improve understanding of facial soft-tissue anatomy so that safe planes of dissection during surgical undermining may be identified for each branch of the facial nerve. Certain anatomical locations more prone to injury and high-risk patient parameters are further emphasized to help minimize the risk of facial nerve injury during rhytidectomy.

    Surfing is a popular UK water-sport. Previous studies investigating surfing injuries have been principally based on trauma from large waves and reef breaks in the US and Australia. Subsequent conclusions and recommendations for the use of protective equipment in surfing may therefore not be relevant in the UK. This study examines the aetiology of surfing injuries in the UK. Data was collected in 2012 using a web-based survey distributed to UK surfing clubs. Surfers recorded time/experience as a surfer, number of episodes spent surfing per month, different breaks surfed and type, frequency and method of any injuries sustained whilst surfing in the UK, including treatment received. Completed surveys were obtained from 130 individuals, M:F division 85:45, median age 28 (range 17-65). 122 surfers reported a total of 335 injuries. Head injuries were the most common (24%) followed by ankle (19%), knee (13%), back (10%), hand/wrist (9%), elbow/shoulder (7%), trunk (7%), neck (4%), hip (4%) and genitalia (3%) injuries. Surfers collided most often with their own boards (31%). The other collisions were with rocks/coral (15%), the sea (11%), other surf boards (10%) the sea bed (7%), other water vessels (2%) and by paddle-boards (1%). Of 327 injuries, cuts/lacerations (31%) were the commonest type of injury, followed by bruises/peri-orbital ecchymoses (24%), joint/ligament sprains (15%), muscle or tendon tears/ruptures (9%), concussion (5%), fractures (3%) and teeth injuries (1%). The remaining 8 injuries were not categorized. 65% of the surfers never required professional medical treatment for their differing injuries. There were no skull fractures and no head injuries required neurosurgical intervention. Surfing injuries in the UK are common. They appear of a similar aetiology to those reported in the literature in countries with a high surfing population, but generally of a lower severity, with few requiring professional treatment, hospital admission or operative

  10. Ischemic preconditioning protects against ischemic brain injury

    Directory of Open Access Journals (Sweden)

    Xiao-meng Ma

    2016-01-01

    Full Text Available In this study, we hypothesized that an increase in integrin αv ß 3 and its co-activator vascular endothelial growth factor play important neuroprotective roles in ischemic injury. We performed ischemic preconditioning with bilateral common carotid artery occlusion for 5 minutes in C57BL/6J mice. This was followed by ischemic injury with bilateral common carotid artery occlusion for 30 minutes. The time interval between ischemic preconditioning and lethal ischemia was 48 hours. Histopathological analysis showed that ischemic preconditioning substantially diminished damage to neurons in the hippocampus 7 days after ischemia. Evans Blue dye assay showed that ischemic preconditioning reduced damage to the blood-brain barrier 24 hours after ischemia. This demonstrates the neuroprotective effect of ischemic preconditioning. Western blot assay revealed a significant reduction in protein levels of integrin αv ß 3, vascular endothelial growth factor and its receptor in mice given ischemic preconditioning compared with mice not given ischemic preconditioning 24 hours after ischemia. These findings suggest that the neuroprotective effect of ischemic preconditioning is associated with lower integrin αv ß 3 and vascular endothelial growth factor levels in the brain following ischemia.

    Pre-exercise stretching and adequate warm-up are important in the prevention of hamstring injuries. A previous mild injury or fatigue may increase the risk of injury. Hamstring muscle tear is typically partial and takes place during eccentric exercise when the muscle develops tension while lengthening, but variation in injury mechanisms is possible. Diagnosis of typical hamstring muscle injury is usually based on typical injury mechanism and clinical findings of local pain and loss of function. Diagnosis of avulsion in the ischial tuberosity, with the need for longer immobilisation, and a complete rupture of the hamstring origin, in which immediate operative treatment is necessary, poses a challenge to the treating physician. X-rays, ultrasonography or magnetic resonance imaging (MRI) may be helpful in differential diagnostics. After first aid with rest, compression, cold and elevation, the treatment of hamstring muscle injury must be tailored to the grade of injury. Conservative treatment is based on a knowledge of the biological background of the healing process of the muscle. Experimental studies have shown that a short period of immobilisation is needed to accelerate formation of the granulation tissue matrix following injury. The length of the immobilisation is, however, dependent on the grade of injury and should be optimised so that the scar can bear the pulling forces operating on it without re-rupture. Mobilisation, on the other hand, is required in order to regain the original strength of the muscle and to achieve good final results in resorption of the connective tissue scar and re-capillarisation of the damaged area. Another important aim of mobilisation--especially in sports medical practice--is to avoid muscle atrophy and loss of strength and extensibility, which rapidly result from prolonged immobilisation. Complete ruptures with loss of function should be operated on, as should cases resistant to conservative therapy in which, in the late phase of

    Patient demographics, behavior, and injury patterns were assessed to inform preventative efforts for reduced incidence of all-terrain vehicle (ATV) trauma. ATV-related injuries treated at a Level I trauma center from 2008 to 2012 were retrospectively reviewed. Patient outcomes and incidence of traumatic brain injury (TBI) were compared by helmet use and alcohol intoxication. Helmet data were available for 304 patients of 404 patients included; of these, 75 (24.7%) wore a helmet. Incidence of TBI was lower in the helmeted (8.0%) versus the unhelmeted subgroup (26.6%) (P injury severity scores, lower intensive-care unit (ICU) admission rates, and shorter ICU and hospital length of stay (LOS) (P injury prevention among ATV users.

    To examine the perception of the preventability of injury and needs on injury prevention knowledge among undergraduates. Stratified sampling and cluster sampling were used to select undergraduate students from 12 classes of three specialized fields of Central South University. A survey was carried out to understand beliefs of the preventability of injuries and knowledge needs on injury prevention. Over 80% of students believed that drowning (605/684), road traffic injuries (601/684), burns and suicide/self-harm (591/684) are most preventable, while merely 59.6% (408/684) and 56.4% (386/684) of students considered cut/pierce and homicide/assault most preventable. The beliefs of preventability of common injuries were not statistically significant between non-public-health medical students, public health students, and non-medical students (P > 0.05), with an exception for poisoning. 18.1% of students (124) reported to received short-term injury training or take lecture for injury prevention, and 27.9% of students (191) had ever read injury-related books. There were 60% (410/684) and 56% (383/684) of students respectively reporting needs for prevention knowledge about poisoning and road traffic injuries. Many undergraduates hold incorrect perception on the preventability of injuries, quite a few report knowledge needs for injury prevention.

    In the United States motor vehicle crashes are the leading cause of death in children. Although laws and public awareness campaigns have increased the use of passive restraints, many children continue to be unrestrained or improperly restrained. Age-appropriate child restraint systems are a vital means to prevent injury and death. The young school-aged child presents unique challenges to standardized vehicle restraint systems. As these children outgrow child safety seats, they frequently are placed in lap/shoulder belt systems designed for the adult. When prematurely graduated to the vehicle's restraint systems they are predisposed to injuries to the abdomen and lumbar spine known as the "seat belt syndrome" or "lap belt complex." These injuries often present subtly, and are not as obvious as the often life-threatening injuries found in the unrestrained pediatric trauma patient. However if undetected or missed these injuries can significantly impact the child's recovery and functional outcome. This article will provide a comprehensive overview of pediatric seat belt injuries. Content will explore the mechanisms responsible for producing the typical patterns of injury, recognition of these potential injuries during the trauma assessment, diagnostic evaluation and management of children with suspected or actual seat belt injuries. Prevention strategies will be discussed that will enable trauma nurses to effectively advocate the use of booster seats for the young school-aged child.

    2014-01-01

    Full Text Available This paper deals with the subject of injury in alpine skiing and snowboarding and the aim was to define the characteristics of injuries and the risk factors as the basis for establishing preventive measures. The types of injuries and risk factors were analyzed by examining previous papers. During the last thirty years, the number of injuries has generally decreased by 50-70%. The changes were recorded in the types of injuries, and the number of certain injuries increased. It was found that there was a mutual difference in the number and structure of the injuries of skiers and snowboarders. Injuries can be classified topologically and according to risk factors. The risk factors may be manifold: the characteristics of the equipment, the characteristics of the trail and snow surface, protective equipment, age, gender, physical fitness, risky behaviours, time of day, skiing discipline, climate factors, the presence of other skiers and others. By the analysis of these factors it was concluded that there were three entities in the implementation of security measures: the state that stipulates laws (relevant ministries, owners or organizers who provide services in skiing (ski centres, ski services, ski schools, clubs and skiers and snowboarders themselves.

    2004-01-01

    Objective: Community based models for injury prevention have become an accepted part of the overall injury control strategy. This systematic review of the scientific literature examines the evidence for their effectiveness in reducing all-cause injury in children 0–14 years of age. Methods: A comprehensive search of the literature was performed using the following study selection criteria: community based intervention study; children under 14 years; outcome measure was injury rates; and either a community control or an historical control was used in the design. Quality assessment and data abstraction were guided by a standardized procedure and performed independently by two authors. Data synthesis was in tabular and text form with meta-analysis not being possible due to the discrepancy in methods and measures between the studies. Results: Thorough electronic and library search techniques yielded only nine formally evaluated community based all-cause child injury prevention programs that have reported actual injury outcomes. Of these nine studies, seven provided high level evidence where contemporary control communities were used for comparison; the remaining two used a pre and post-design or time trend analysis where historical data from the community were used as the comparison. Only three of the seven studies with contemporary control communities found significant effect of the intervention; the two studies without controls noted significant reductions in injury rates after the intervention period. Conclusion: There is a paucity of research from which evidence regarding the effectiveness of community based childhood injury prevention programs can be obtained and hence a clear need to increase the effort on developing this evidence base.

    Oxidative stress plays an important role in cadmium-induced liver injury. Nuclear factor erythroid 2-related factor 2 (Nrf2) is a transcription factor that up-regulates cytoprotective genes in response to oxidative stress. To investigate the role of Nrf2 in cadmium-induced hepatotoxicity, Nrf2-null mice, wild-type mice, kelch-like ECH-associated protein 1-knockdown (Keap1-KD) mice with enhanced Nrf2, and Keap1-hepatocyte knockout (Keap1-HKO) mice with maximum Nrf2 activation were treated with cadmium chloride (3.5 mg Cd/kg, i.p.). Blood and liver samples were collected 8 h thereafter. Cadmium increased serum alanine aminotransferase (ALT) and lactate dehydrogenase (LDH) activities, and caused extensive hepatic hemorrhage and necrosis in the Nrf2-null mice. In contrast, Nrf2-enhanced mice had lower serum ALT and LDH activities and less morphological alternations in the livers than wild-type mice. H{sub 2}DCFDA (2′,7′-dichlorodihydrofluoresein diacetate) staining of primary hepatocytes isolated from the four genotypes of mice indicated that oxidative stress was higher in Nrf2-null cells, and lower in Nrf2-enhanced cells than in wild-type cells. To further investigate the mechanism of the protective effect of Nrf2, mRNA of metallothionein (MT) and other cytoprotective genes were determined. Cadmium markedly induced MT-1 and MT-2 in livers of all four genotypes of mice. In contrast, genes involved in glutathione synthesis and reducing reactive oxygen species, including glutamate-cysteine ligase (Gclc), glutathione peroxidase-2 (Gpx2), and sulfiredoxin-1 (Srxn-1) were only induced in Nrf2-enhanced mice, but not in Nrf2-null mice. In conclusion, the present study shows that Nrf2 activation prevents cadmium-induced oxidative stress and liver injury through induction of genes involved in antioxidant defense rather than genes that scavenge Cd. -- Highlights: ► Cadmium caused extensive hepatic hemorrhage and necrosis in Nrf2-null mice. ► Keap1-KD and Keap1-HKO mice

    Sulforaphane, a precursor of glucosinolate in cruciferous vegetables such as broccoli and cauliflower, has been shown to protect brain ischemic injury. In this study, we examined the effect of systemic administration of sulforaphane on retinal ischemic reperfusion injury. Intraocular pressure was elevated in two groups of C57BL/6 mice (n = 8 per group) for 45 min to induce retinal ischemic reperfusion injury. Following retinal ischemic reperfusion injury, vehicle (1% DMSO saline) or sulforaphane (25 mg/kg/day) was administered intraperitoneally daily for 5 days. Scotopic electroretinography (ERG) was used to quantify retinal function prior to and one-week after retinal ischemic insult. Retinal morphology was examined one week after ischemic insult. Following ischemic reperfusion injury, ERG a- and b-wave amplitudes were significantly reduced in the control mice. Sulforaphane treatment significantly attenuated ischemic-induced loss of retinal function as compared to vehicle treated mice. In vehicle treated mice, ischemic reperfusion injury produced marked thinning of the inner retinal layers, but the thinning of the inner retinal layers appeared significantly less with sulforaphane treatment. Thus, sulforaphane may be beneficial in the treatment of retinal disorders with ischemic reperfusion injury. Copyright © 2015 Elsevier Ltd. All rights reserved.

    To define target populations for sports injury prevention programs. A computer-assisted telephone survey on sports injuries and sports participation during 2000-2005 using a 3-month recall period. Data obtained from a representative sample of Dutch citizens. Fifty-eight thousand four hundred five Dutch citizens aged older than 3 years. Age, gender, and type of sports were used to distinguish subgroups with a substantial contribution to sports injuries. The absolute number of sports injuries, the incidence of sports injuries per 10,000 hours, the severity, and costs of sports injuries. Sports participation was associated with 1.5 million injuries per year and 10 injuries per 10,000 hours; of these, 50% had to be treated medically. Two-thirds of all medically treated sports injuries were associated with 9 sports (representing 18 subpopulations, all younger than 55 years): outdoor soccer (males 4-54 years and females 4-17 years), indoor soccer (males 18-34 years), tennis (males/females 35-54 years), volleyball (females 18-54 years), field hockey (males 18-34 years and females 4-17 years), running/jogging (males/females 35-54 years), gymnastics (males/females 4-17 years), skiing/snowboarding (males 4-17 years and females 18-34 years), and equestrian sports (females 18-34 years). These groups showed more than average injury rates and covered two-thirds of all direct and indirect costs (euro 400 million). The survey identified the most important (sports-, age-, and gender-specific) target populations for injury prevention programs in the Netherlands. Sports participants aged older than 55 years were excluded from these target groups because of their limited contribution to the total sports injury problem.

    This original prospective cohort study was conducted in an attempt to significantly reduce the incidence and the severity of injuries in an intervention cohort as compared to a two-season historical cohort, and to provide recommendations to the International Federation of Football (IFAF) pertaining to prevention measures to make the game safer. A total of 1,260 amateur male (mean age: 20.4 ± 3.9 years) and 244 female (mean age: 18.5 ± 1.7 years) players participated in the study. Four prevention measures were implemented: the no-pocket rule, self-fitting mouth guards, ankle braces (for those players with recurrent ankle sprains) and an injury treatment information brochure. All time-loss injuries sustained in game sessions were recorded by the off-the-field medical personnel and followed up by a more detailed phone injury surveillance questionnaire. There was a 54 % reduction in the total number of injuries and a significant reduction in the incidence rate and incidence proportion between the intervention cohorts as compared to the historical cohort (p injuries in any of the body parts, except for in hand/wrist injuries related to the use of pockets (p injuries (p injuries can be significantly reduced in flag football.

    Pretreatment with scutel aria baicalensis stem-leaf total flavonoid has protective effects against ischemia and attenuates myocardial ischemia-reperfusion injury. In this study, rats were given scu-tel aria baicalensis stem-leaf total flavonoid intragastrical y at 50, 100, and 200 mg/kg per day for 7 days before focal cerebral ischemia-reperfusion injury models were established using the suture method. We then determined the protective effects of scutel aria baicalensis stem-leaf total flavo-noid pretreatment on focal cerebral ischemia-reperfusion injury. Results showed that neurological deficit scores increased, infarct volumes enlarged, apoptosis increased and Bcl-2 and Bax protein expression were upregulated at 24 hours after reperfusion. Pretreatment with scutel aria baicalensis stem-leaf total flavonoid at any dose lowered the neurological deficit scores, reduced the infarct volume, prevented apoptosis in hippocampal cells, attenuated neuronal and blood-brain barrier damage and upregulated Bcl-2 protein expression but inhibited Bax protein expression. Doses of 100 and 200 mg/kg were the most efficacious. Our findings indicate that pretreatment with scutel a-ria baicalensis stem-leaf total flavonoid at 100 and 200 mg/kg can improve the neurological func-tions and have preventive and protective roles after focal cerebral ischemia-reperfusion injury.

    Rugby Union ("rugby") participants have a higher than average risk of injury compared with participants of other popular team sports. BokSmart, a nationwide injury prevention program was launched in South Africa in mid-2009, with the goal of reducing catastrophic head/neck (serious) injuries in players. The program provides injury prevention information to coaches and referees. This study investigated if BokSmart has been associated with a reduction in these injuries. The BokSmart program collected data on all South African rugby-related serious injuries since 2008. Using a Poisson regression, injury numbers were compared pre-BokSmart (2008-2009) to the years post-implementation (2010-2013). Player numbers were assumed to be constant throughout this evaluation: junior = 529,483; senior = 121,663. In junior players, the "post-BokSmart" period had 2.5 less annual serious injuries than "pre-BokSmart" (incidence rate ratio: 0.6, 95% confidence interval: 0.5-0.7, P < 0.000). In contrast, there was no significant difference in these periods in seniors. The absence of effect in seniors may be a result of fewer players or of differences in effectiveness of BokSmart in this group--future studies should investigate these questions.

    Work related back injuries among hospital personnel account for high volume, high cost workers' compensation claims. These injuries can be life altering experiences, affecting both the personal and professional lives of injured workers. Lifting must be viewed as a skill involving specialized training and mandated use of mechanical equipment, rather than as a random task performed by numerous health care providers. The use of a lift team specially trained in body mechanics, lifting techniques, and the use of mandated mechanical equipment can significantly affect injury data, financial outcomes, and employee satisfaction. The benefits of a lift team extend beyond the effect on injury and financial outcomes--they can be used for recruitment and retention strategies, and team members serve as mentors to others by demonstrating safe lifting techniques. Ultimately, a lift team helps protect a valuable resource--the health care worker.

  15. Ethyl Pyruvate Prevents Methyglyoxal-Induced Retinal Vascular Injury in Rats

    2013-01-01

    Full Text Available Pyruvate is an endogenous antioxidant substance. The aim of this study was to investigate the protective effects of ethyl pyruvate (EP on retinal vascular injury in diabetic retinopathy. To investigate the protective effect of EP on vascular cell apoptosis and blood-retinal barrier (BRB breakage, we have used intravitreally methylglyoxal-(MGO- injected rat eyes. Apoptosis of the retinal vascular cell that was stimulated by the intravitreal injection of MGO was evidently attenuated by the EP treatment. EP exerts inhibitory effect on MGO-induced vascular cell apoptosis by blocking oxidative injury. In addition, EP treatment prevented MGO-induced BRB breakage and the degradation of occludin, an important tight junction protein. These observations suggest that EP acts through an antioxidant mechanism to protect against oxidative stress-induced apoptosis in retinal vessels.

    Stojanovic, Marko D; Ostojic, Sergej M

    2011-04-01

    Stretching exercises are regularly recommended as a part of football-training sessions and in preparation for competition. There is little sound empirical evidence, however, to substantiate the role of stretching exercises and consequently increased flexibility on injury prevention in football. Furthermore, in the last decade or so, fundamental research has shed some light on the biomechanical adaptation of the muscle-tendon unit following different stretching protocols, improving knowledge about the topic and enabling better understanding of the stretching-injury relationship. The purpose of this review is to examine the literature on the role of stretching and/or increased flexibility on injury prevention in football, with presented results analyzed in the context of the up-to-date basic science research evidence.

    Injuries of the hand are common and sometimes more serious than it appears on a non-specialist initial examination. They are a public health issue with some major impact on the continued activity of patients who have been victims of those injuries. The European Federation of Hand Emergency Services (FESUM) accredits SOS Hand centers, dedicated hand trauma organizations in which the specialized medical cares is optima, avoiding the loss of chance to inadequate primary orientation. If nevertheless a serious injury leaves a debilitating sequela Hand Prevention networks, organized by practitioners of SOS Hand centers, help patients establish a process of socio-professional rehabilitation as soon as possible. These networks organize primary, secondary and tertiary prevention of hand trauma and disabilities that can accompany them. Innovative organizations, they resemble a national association that supports the development of new structures. They are open to all professionals of health and their patients, members or not of the network.

Past years' eHealth is emerging and mobile applications (apps) helping to prevent SPRIs are appearing. To review the content of iPhone and iPad apps containing a claim to prevent sports and physical activity-related injuries and to appraise this claim against best available scientific evidence. The US iTunes App Store was searched using the keywords 'injury', 'prevention' and 'rehabilitation'. Apps within the categories 'health & fitness', 'sports' and 'medical' containing a preventive claim in the app name, description or screenshots were included. Claims were extracted and a search for best available evidence was performed. Eighteen apps met our inclusion criteria. Four of these apps contained claims for which evidence was available: three apps covered ankle sprains and provided information on taping or neuromuscular training. Of these three apps, one app also provided information on prevention of dental injury with mouth guards. One app provided a routine to prevent anterior cruciate ligament injury. The main focus of the five apps was running injury prevention; for their content evidence of absence of efficacy was found. For nine apps no evidence supporting their content was found. f 18 apps included, only four contained claims that could be supported by available literature and five apps contained false claims. This lack of scientifically sound apps provides an opportunity for caretakers to develop apps with evidence-based claims to prevent SPRIs.

    Full Text Available Intentional and unintentional injury is the leading cause of death and potential years of life lost in the first four decades of life in industrialized countries around the world. Despite surgical innovations and improved access to emergency care, research has shown that certain populations remain particularly vulnerable to the risks and consequences of injury. Recent evidence has shown that the analytical, data linkage, and mapping tools of geographic information systems (GIS technology provide can further address these determinants and identify populations in need. This paper traces the history of injury prevention and discusses current and future challenges in furthering our understanding of the determinants of injury through the use of GIS.

    This investigation was undertaken to study the early protective effects of Iloprost, a stable analogue of prostacyclin, after spinal cord injury in rabbit. Sixteen adult male rabbits (New Zealand Albino) were injured by application of epidural aneurysm clip. Eight rabbits received an intravenous (i.v.) infusion of 30 micrograms kg-1 Iloprost, and eight rabbits received an infusion of saline (SF). Treatment with Iloprost started immediately after spinal cord injury and continued for one hour. Evoked potentials were recorded for each rabbit at one, 15, and 60 minutes after the spinal cord injury. Twenty-four hours later, all the rabbits were deeply anesthetized and spinal cords were removed for histopathological examinations. There was no meaningful statistical difference between cortical somatosensorial evoked potentials (CSEP) of the saline and Iloprost group. However, light and electron microscopic studies showed that the Iloprost treated group had moderate protection of myelin and axons; and limited edema. These results suggest that intravenous Iloprost treatment after spinal cord injury has a highly protective effect without any side effects.

  6. Erythropoietin-mediated tissue protection: reducing collateral damage from the primary injury response.

    Science.gov (United States)

    Brines, M; Cerami, A

    2008-11-01

    In its classic hormonal role, erythropoietin (EPO) is produced by the kidney and regulates the number of erythrocytes within the circulation to provide adequate tissue oxygenation. EPO also mediates other effects directed towards optimizing oxygen delivery to tissues, e.g. modulating regional blood flow and reducing blood loss by promoting thrombosis within damaged vessels. Over the past 15 years, many unexpected nonhaematopoietic functions of EPO have been identified. In these more recently appreciated nonhormonal roles, locally-produced EPO signals through a different receptor isoform and is a major molecular component of the injury response, in which it counteracts the effects of pro-inflammatory cytokines. Acutely, EPO prevents programmed cell death and reduces the development of secondary, pro-inflammatory cytokine-induced injury. Within a longer time frame, EPO provides trophic support to enable regeneration and healing. As the region immediately surrounding damage is typically relatively deficient in endogenous EPO, administration of recombinant EPO can provide increased tissue protection. However, effective use of EPO as therapy for tissue injury requires higher doses than for haematopoiesis, potentially triggering serious adverse effects. The identification of a tissue-protective receptor isoform has facilitated the engineering of nonhaematopoietic, tissue-protective EPO derivatives, e.g. carbamyl EPO, that avoid these complications. Recently, regions within the EPO molecule mediating tissue protection have been identified and this has enabled the development of potent tissue-protective peptides, including some mimicking EPO's tertiary structure but unrelated in primary sequence.

    2010-08-10

    To prevent pressure injuries research indicates the importance of focusing on three key areas of practice: continence, skin hygiene and nutrition. These are a synergistic trio and many patients require considered management in all three areas. In addition to targeting specific aspects of nursing care in these areas, it is also crucial that there is organisational buy-in for strategic initiatives. Some of the ways that we achieved this are outlined below: Support from managerial level by presenting evidence and education to senior nurses and directors. Nurse unit managers completed individual ward action plans outlining their individual commitments to reducing pressure injuries. Providing support and education to staff to choose and use continence products effectively. Support from allied health colleagues in prevention of pressure injuries. After implementing the actions described above, pressure injury prevalence at the Prince Charles Hospital in Brisbane decreased from 13.78% in 2008 to 5.15% in 2010, representing a 62% reduction overall. Of these pressure injuries, 53% were stage one.

  8. Diabetic Inhibition of Preconditioning- and Postconditioning-Mediated Myocardial Protection against Ischemia/Reperfusion Injury

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Ischemic preconditioning (IPC or postconditioning (Ipost is proved to efficiently prevent ischemia/reperfusion injuries. Mortality of diabetic patients with acute myocardial infarction was found to be 2–6 folds higher than that of non-diabetic patients with same myocardial infarction, which may be in part due to diabetic inhibition of IPC- and Ipost-mediated protective mechanisms. Both IPC- and Ipost-mediated myocardial protection is predominantly mediated by stimulating PI3K/Akt and associated GSK-3β pathway while diabetes-mediated pathogenic effects are found to be mediated by inhibiting PI3K/Akt and associated GSK-3β pathway. Therefore, this review briefly introduced the general features of IPC- and Ipost-mediated myocardial protection and the general pathogenic effects of diabetes on the myocardium. We have collected experimental evidence that indicates the diabetic inhibition of IPC- and Ipost-mediated myocardial protection. Increasing evidence implies that diabetic inhibition of IPC- and Ipost-mediated myocardial protection may be mediated by inhibiting PI3K/Akt and associated GSK-3β pathway. Therefore any strategy to activate PI3K/Akt and associated GSK-3β pathway to release the diabetic inhibition of both IPC and Ipost-mediated myocardial protection may provide the protective effect against ischemia/reperfusion injuries.

    Enhancement of renal sympathetic nerve activity during renal ischemia and its consequent effect on norepinephrine overflow from nerve endings after reperfusion play important roles in the development of ischemic acute kidney injury. In the present study, we evaluated whether moxonidine, an alpha(2)-adrenaline/I(1)-imidazoline receptor agonist which is known to elicit sympathoinhibitory action, would prevent the post-ischemic renal injury. Ischemic acute kidney injury was induced by clamping the left renal artery and vein for 45 min followed by reperfusion, 2 weeks after contralateral nephrectomy. Intravenous (i.v.) injection of moxonidine at a dose of 360 nmol/kg to ischemic acute kidney injury rats suppressed the enhanced renal sympathetic nerve activity during the ischemic period, to a degree similar to findings with intracerebroventricular (i.c.v.) injection of moxonidine at a dose of 36 nmol/kg. On the other hand, suppressive effects of the i.v. treatment on renal venous norepinephrine overflow, renal dysfunction and tissue injury in the post-ischemic kidney were significantly greater than those elicited by the i.c.v. treatment. These results suggest that renoprotective effects of moxonidine on ischemic acute kidney injury probably result from its suppressive action on the ischemia-enhanced renal sympathetic nerve activity followed by norepinephrine spillover from the nerve endings of the post-ischemic kidney.

    Full Text Available OBJECTIVES: Tissue injury occurs following reperfusion after creation of ischemia. Plenty of chemical agents have been shown to protect from such an injury. We planned to evaluate the protective effect of dexpanthenol (dxp in ischemia-reperfusion injury. MATERIAL and METHODS: 24 adult rats were used and divided into 3 groups. A right nephrectomy was performed through a median laparotomy incision in all groups. Additionally, in group 1 (sham group, left nephrectomy was made 6 hours later without creation of ischemia. In group 2 (Saline group, the left kidney was left ischemic for 1 hour and reperfusion was established for 6 hours. Saline was administered intraperitoneally thirty minutes before creation of ischemia and just before reperfusion. In group 3 (Dexpanthenol group, the left kidney was left ischemic for 1 hour and reperfusion was established for 6 hours. Dxp (500 mg/kg was administered intraperitoneally thirty minutes before creation of ischemia and just before reperfusion. A left nephrectomy was performed at the end of the 6 hours of reperfusion. Nephrectomy specimens were histopathologically analysed for congestion, inflammation and necrosis. Tissue NO, glutathione reductase, catalase and MDA levels were measured. RESULTS: There was no significant differences between the groups histopathologically or biochemically. CONCLUSION: Dexpanthenol is the biologically active form of pantothenic acid and has an antioxidant effect. Our study was not in correlation with the literature regarding a protective effect of dxp on various organs via its antioxidant effect.

Here we explored whether platelets can help attenuate lung injury in mice resulting from extracorporeal circulation (ECC)-induced systemic inflammatory responses. Mice were subjected to ECC for 30 min, then treated with phosphate-buffered saline, platelets, the GPIIb/IIIa inhibitor Tirofiban, or the combination of platelets and Tirofiban. Blood and lung tissues were harvested 60 min later, and lung injury and inflammatory status were assessed. As expected, ECC caused systemic inflammation and pulmonary dysfunction, and platelet transfusion resulted in significantly milder lung injury and higher lung function. It also led to greater numbers of circulating platelet-leukocyte aggregates and greater platelet accumulation in the lung. Platelet transfusion was associated with higher production of transforming growth factor-β and as well as lower levels of tumour necrosis factor-α and neutrophil elastase in plasma and lung. None of these platelet effects was observed in the presence of Tirofiban. Our results suggest that, at least under certain conditions, platelets can protect lung from injury induced by systemic inflammatory responses. PMID:28155889

    Modern ballistic helmets defeat penetrating bullets by energy transfer from the projectile to the helmet, producing helmet deformation. This deformation may cause severe injuries without completely perforating the helmet, termed "behind armor blunt trauma" (BABT). As helmets become lighter, the likelihood of larger helmet backface deformation under ballistic impact increases. To characterize the potential for BABT, seven postmortem human head/neck specimens wearing a ballistic protective helmet were exposed to nonperforating impact, using a 9 mm, full metal jacket, 124 grain bullet with velocities of 400-460 m/s. An increasing trend of injury severity was observed, ranging from simple linear fractures to combinations of linear and depressed fractures. Overall, the ability to identify skull fractures resulting from BABT can be used in forensic investigations. Our results demonstrate a high risk of skull fracture due to BABT and necessitate the prevention of BABT as a design factor in future generations of protective gear.

    simulate a typical ice hockey injury. Peak force, energy and power were calculated from the force-displacement data collected from the 7 matched pair trials. The cadavers were then dissected to identify the extent of the injury the skin and Achilles tendon from blade impact. Analysis of variance was used to test for a significant difference between the groups. Results: None (0/7) of the achilles tendons were lacerated when protected with Kevlar® reinforced socks; whereas all (7/7) achilles tendons tested using the standard synthetic sock were completely severed (Figure 1). Peak force (4030 +/- 1191 N vs. 2037 +/- 729 N), energy (81.4 +/- 38.9 J vs. 26.3 +/- 13.2 J) and power (471.2 +/- 166.7 W vs. 258.3 +/- 93.5 W) were all significantly (pKevlar® reinforced sock group compared to the standard synthetic sock group in our testing model (Figures 2 and 3). Conclusion: The Kevlar® reinforced socks provided significantly more cut resistance and were able to withstand a significantly larger peak force, energy and power from skate blade impact and prevent achilles tendon laceration when compared to standard synthetic hockey socks in a biomechanical testing model using human cadaver limbs. This is the first investigation to address the benefits of wearing Kevlar® reinforced hockey socks in a simulated model of hockey skate injuries and our results suggest a significant protective effect from the use of Kevlar® reinforced socks against hockey skate injuries.

    Rugby union football has long been one of the most popular sports in the world. Its popularity and number of participants continue to increase in the United States. Until 1995, rugby union primarily was an amateur sport. Worldwide there are now flourishing professional leagues in many countries, and after a long absence, rugby union will be returning to the Olympic games in 2016. In the United States, rugby participation continues to increase, particularly at the collegiate and high school levels. With the increase in rugby professional athletes and the reported increase in aggressive play, there have been changes to the injury patterns in the sport. There is still significant need for further epidemiologic data as there is evidence that injury prevention programs and rule changes have been successful in decreasing the number of catastrophic injuries in rugby union.

    Currently, there is no overview of the incidence and (volleyball-specific) risk factors of musculoskeletal injuries among volleyball players, nor any insight into the effect of preventive measures on the incidence of injuries in volleyball. This study aimed to review systematically the scientific evidence on the incidence, prevalence, aetiology and preventive measures of volleyball injuries. To this end, a highly sensitive search strategy was built based on two groups of keywords (and their synonyms). Two electronic databases were searched, namely Medline (biomedical literature) via Pubmed, and SPORTDiscus (sports and sports medicine literature) via EBSCOhost. The results showed that ankle, knee and shoulder injuries are the most common injuries sustained while playing volleyball. Results are presented separately for acute and overuse injuries, as well as for contact and non-contact injuries. Measures to prevent musculoskeletal injuries, anterior knee injuries and ankle injuries were identified in the scientific literature. These preventive measures were found to have a significant effect on decreasing the occurrence of volleyball injuries (for instance on ankle injuries with a reduction from 0.9 to 0.5 injuries per 1000 player hours). Our systematic review showed that musculoskeletal injuries are common among volleyball players, while effective preventive measures remain scarce. Further epidemiological studies should focus on other specific injuries besides knee and ankle injuries, and should also report their prevalence and not only the incidence. Additionally, high-quality studies on the aetiology and prevention of shoulder injuries are lacking and should be a focus of future studies.

  4. New PPE Policy Will Help Prevent Injuries | Poster

    Science.gov (United States)

    By Ashley Shoemaker, Guest Writer In January 2013, a revised policy on personal protective equipment (PPE) was approved for all government and contractor employees at NCI at Frederick. This new policy was driven by a high number of eye injuries at NCI at Frederick (56 between 2007 and 2012) that were directly related to inadequate PPE. The Occupational Safety and Health Act states that each employer is responsible for identifying hazards in the workplace and determining what kind of PPE is necessary.

    Full Text Available Body-worn inertial sensors have enabled motion capture outside of the laboratory setting. In this work, an inertial measurement unit was attached to the upper arm to track and discriminate between shoulder motion gestures in order to help prevent shoulder over-use injuries in athletics through real-time preventative feedback. We present a detection and classification approach that can be used to count the number of times certain motion gestures occur. The application presented involves tracking baseball throws and volleyball serves, which are common overhead movements that can lead to shoulder and elbow overuse injuries. Eleven subjects are recruited to collect training, testing, and randomized validation data, which include throws, serves, and seven other exercises that serve as a large null class of similar movements, which is analogous to a realistic usage scenario and requires a robust estimator.

    In the last years, shoulder injuries have represented an increasing health problem in soccer players. The goalkeepers are more exposed to shoulder disorders than other field players. Injury prevention exercises for upper limbs were cited in few studies involving throwing athletes, but we know that goalkeepers need a specific program. The purpose of this study is to describe the development of an adapted Fédération Internationale de Football Association (FIFA) 11+ program, namely the FIFA 11+ shoulder, which targets the prevention of shoulder injuries in soccer goalkeepers. The FIFA 11+ shoulder program is structured into three parts: general warming-up exercises, exercises to improve strength and balance of the shoulder, elbow, wrist, and finger muscles, and advanced exercises for core stability and muscle control. The exercises were selected based on recommendations from studies demonstrating high electromyographic activity. PMID:27563262

  8. Optimal Impact Isolation for Injury Prevention Evaluated by the Head Injury Criterion

    Directory of Open Access Journals (Sweden)

    D.V. Balandin

    2007-01-01

    Full Text Available The optimal control of the deceleration of a particle moving along a straight line after an impact against an isolated surface is considered. The force applied to the particle by the surface is treated as the control variable. The deceleration distance is minimized subject to a constraint on the Head Injury Criterion functional. This functional is an integral criterion that is utilized in engineering biomechanics to evaluate the expected severity of impact-induced head injury of a human being. The solution obtained provides characteristics of the limiting capabilities for the prevention of head injuries by means of an impact isolator, such as a coating of the surface against which the impacts occur. The head injuries can be due to impact occurrences, including traffic crashes, falling, and contacts with ballistic objects.

  9. Evaluation, management, rehabilitation, and prevention of anterior cruciate ligament injury: current concepts.

    Micheo, William; Hernández, Liza; Seda, Carlos

    2010-10-01

    The anterior cruciate ligament (ACL) is essential for both static and dynamic stability of the knee. It is commonly injured during sports activities by noncontact mechanisms that include landing with the knee in valgus and extension, sudden deceleration, change of direction, and rotation. Several modifiable and nonmodifiable risk factors predispose athletes to this injury, especially women. Early diagnosis, treatment directed to protect secondary knee structures, and rehabilitation play an important role in the management of ACL injury. Despite a lack of scientifically validated and published guidelines to help clinicians decide between conservative or surgical treatment, criteria such as pain, recurrent instability, injury to secondary structures, and desired level of activity should be considered. Accelerated rehabilitation protocols for patients who have and have not undergone an operation are available and recommended with goals of reducing complications such as recurrent injury, loss of motion, residual weakness, and associated osteoarthritis. However, injury prevention protocols could be the next big step in management of ACL injury with emphasis on reducing modifiable risk factors in susceptible individuals who participate in sports.

    Concussion is a serious problem in many contact sports, including rugby union football. The study's primary aim was to measure the efficacy of padded headgear in reducing the rates of head injury or concussion. A cluster randomized controlled trial with three arms was conducted with rugby union football teams as the unit of randomization. Teams consisted of males participating in under 13-, 15-, 18-, and 20-yr age group competitions. The interventions were "standard" and "modified" padded headgear. Headgear wearing and injury were measured for each study team at each game over two seasons. Eighty-two teams participated in year 1 and 87 in year 2. A total of 1493 participants (10,040 player hours) were in the control group, 1128 participants (8170 player hours) were assigned to the standard headgear group, and 1474 participants (10,650 player hours) were assigned to the modified headgear group. The compliance rates were low in all groups, but 46% of participants wore standard headgear. An intention-to-treat analysis showed no differences in the rates of head injury or concussion between controls and headgear arms. Incidence rate ratios for standard headgear wearers referenced to controls were 0.95 and 1.02 for game and missed game injuries. Analyses of injury rates based on observed wearing patterns also showed no significant differences. Incidence rate ratios for standard headgear wearers referenced to nonwearers were 1.11 and 1.10 for game and missed game injuries. Padded headgear does not reduce the rate of head injury or concussion. The low compliance rates are a limitation. Although individuals may choose to wear padded headgear, the routine or mandatory use of protective headgear cannot be recommended.

ACL injuries in skeletally immature athletes present a challenge, as reconstruction must preserve the physis of the distal femur and of the proximal tibia to avoid growth disturbances. Historically, a skeletally immature athlete with an ACL injury was treated with a brace and activity modification until skeletal maturity, with ACL reconstruction being performed at that time in the “non-copers” who experienced instability. More recently, evidence has shown that delayed reconstruction may lead to increased damage to the meniscus and articular cartilage. As a result, early reconstruction is favored to protect the meniscus and allow continued physical activity. While adolescents at or those near skeletal maturity may be treated with standard reconstruction techniques, they may result in growth disturbances in younger athletes with significant growth remaining. In response to the growing need for ACL reconstruction techniques in skeletally immature individuals, physeal-sparing and physeal-respecting reconstruction techniques have been developed. In addition to the advancements in surgical technique, ACL injury prevention has also gained attention. This growing interest in ACL prevention is in part related to the high risk of ACL re-tear, either of the ACL graft or of the contralateral ACL, in children and adolescents. Recent reports indicate that well-designed neuromuscular training programs may reduce the risk of primary and subsequent ACL injuries. Keywords

    There are a variety of biologics, vaccines, antibiotics, and hormones used in animal agriculture. Depending upon the procedure or pharmaceutical used, accidental injections or product exposures can result in mild to severe injuries. Needlestick injury (NSI) prevention, research, and education for veterinarians and agriculture workers is limited. The objective of this study was to collect and review published case reports and case series/surveys on human needlestick exposure to veterinary biologics and to summarize needlestick prevention strategies for agricultural workers/veterinarians. A search was conducted of PubMed and Centre for Agriculture Bioscience International (CABI) databases. References were reviewed to identify additional articles. NSI among agricultural workers were primarily included in this review. Thirty articles were applicable to exposures in agricultural settings. Relevant literature consisted of case reports, survey/case series articles, prevention documents, and background articles. Fifty-nine case patients were identified. Most of these cases were associated with exposures to specific vaccines or veterinary products. Injury location was identified from 36 individuals: 24 (67%) NSI to the hands, 10 (28%) injuries to the legs, and 2 to other body locations. Of the 59 cases, 20 (34%) involved oil-adjuvant vaccines. Evidence of hospitalization was recorded for 30 case patients. The length of hospitalization was available from 11 case patients. Median length of hospitalization was 3 days (range: 1-4). Surgical intervention was reported in 25 case patients. Outcome information was available on 30 case patients. Fifteen made a complete recovery within 2 weeks of treatment, 14 had residual sequelae attributed to the injury, and there was 1 reported death. Of the 13 survey/case series articles: 2 focused on oil-adjuvant products, 1 on Brucellosis RB-51 vaccine, 3 on tilmicosin, 1 on Salmonella enteritidis vaccine, 1 on high-pressure injection, and 5

    Several studies have characterized the cellular and molecular mechanisms of hepatocyte injury caused by the retention of hydrophobic bile acids (BAs) in cholestatic diseases. BAs may disrupt cell membranes through their detergent action on lipid components and can promote the generation of reactive oxygen species that, in turn, oxidatively modify lipids, proteins, and nucleic acids, and eventually cause hepatocyte necrosis and apoptosis. Several pathways are involved in triggering hepatocyte apoptosis. Toxic BAs can activate hepatocyte death receptors directly and induce oxidative damage, thereby causing mitochondrial dysfunction, and induce endoplasmic reticulum stress. When these compounds are taken up and accumulate inside biliary cells, they can also cause apoptosis. Regarding extrahepatic tissues, the accumulation of BAs in the systemic circulation may contribute to endothelial injury in the kidney and lungs. In gastrointestinal cells, BAs may behave as cancer promoters through an indirect mechanism involving oxidative stress and DNA damage, as well as acting as selection agents for apoptosis-resistant cells. The accumulation of BAs may have also deleterious effects on placental and fetal cells. However, other BAs, such as ursodeoxycholic acid, have been shown to modulate BA-induced injury in hepatocytes. The major beneficial effects of treatment with ursodeoxycholic acid are protection against cytotoxicity due to more toxic BAs; the stimulation of hepatobiliary secretion; antioxidant activity, due in part to an enhancement in glutathione levels; and the inhibition of liver cell apoptosis. Other natural BAs or their derivatives, such as cholyl-Nmethylglycine or cholylsarcosine, have also aroused pharmacological interest owing to their protective properties.

    Several important methodological issues need to be considered when designing sports injury case-control studies. Major design goals for case-control studies include the accounting for prior injury risk exposure, and optimal definitions of both cases and suitable controls are needed to ensure this. This article reviews methodological aspects of published sports injury case-control studies, particularly with regard to the selection of controls. It argues for a new approach towards selecting controls for case-control studies that draws on an interface between epidemiological and biomechanical concepts. A review was conducted to identify sport injury case-control studies published in the peer-review literature during 1985-2008. Overall, 32 articles were identified, of which the majority related to upper or lower extremity injuries. Matching considerations were used for control selection in 16 studies. Specific mention of application of biomechanical principles in the selection of appropriate controls was absent from all studies, including those purporting to evaluate the benefits of personal protective equipment to protect against impact injury. This is a problem because it could lead to biased conclusions, as cases and controls are not fully comparable in terms of similar biomechanical impact profiles relating to the injury incident, such as site of the impact on the body. The strength of the conclusions drawn from case-control studies, and the extent to which results can be generalized, is directly influenced by the definition and recruitment of cases and appropriate controls. Future studies should consider the interface between epidemiological and biomechanical concepts when choosing appropriate controls to ensure that proper adjustment of prior exposure to injury risk is made. To provide necessary guidance for the optimal selection of controls in case-control studies of interventions to prevent sports-related impact injury, this review outlines a new case

    To investigated the protective potential of ethanol extracts of Scutellaria baicalensis (S. baicalensis ) against lipopolysaccharide (LPS)-induced liver injury. Methods: Dried roots of S. baicalensis were extracted with ethanol and concentrated to yield a dry residue. Mice were administered 200 mg/kg of the ethanol extracts orally once daily for one week. Animals were subsequently administered a single dose of LPS (5 mg/kg of body weight, intraperitoneal injection). Both protein and mRNA levels of cytokines, such as tumor necrosis factor alpha, interleukin-1β, and interleukin-6 in liver tissues were evaluated by ELISA assay and quantitative PCR. Cyclooxygenase-2, inducible nitric oxide synthase, and nuclear factor-κB protein levels in liver tissues were analyzed by western blotting. Results: Liver injury induced by LPS significantly increased necrosis factor alpha, interleukin-1β, interleukin-6, cyclooxygenase-2, inducible nitric oxide synthase, and nuclear factor-κB in liver tissues. Treatment with ethanol extracts of S. baicalensis prevented all of these observed changes associated with LPS-induced injury in liver mice. Conclusions: Our study showed that S. baicalensis is potentially protective against LPS-induced liver injury in mice.

    The present study was undertaken to investigate the possible protective effect of L-carnosine (CAR), an endogenous dipeptide of alanine and histidine, on carbon tetrachloride (CCl4)-induced hepatic injury. Liver injury was induced in male Sprague-Dawley rats by intraperitoneal (i.p.) injections of CCl4, twice weekly for six weeks. CAR was administered to rats daily, at dose of 250 mg/kg, i.p. At the end of six weeks, blood and liver tissue specimens were collected. Results show that CAR treatment attenuated the hepatic morphological changes, necroinflammation and fibrosis induced by CCl4, as indicated by hepatic histopathology scoring. In addition, CAR treatment significantly reduced the CCl4-induced elevation of liver-injury parameters in serum. CAR treatment also combatted oxidative stress; possibly by restoring hepatic nuclear factor erythroid 2-related factor 2 (Nrf-2) levels. Moreover, CAR treatment prevented the activation of hepatic stellate cells (HSCs), as indicated by reduced α-smooth muscle actin (α-SMA) expression in the liver, and decreased hepatic inflammation as demonstrated by a reduction in hepatic tumor necrosis factor-α (TNF-α) and restoration of interleukin-10 (IL-10) levels. In conclusion, CCl4-induced hepatic injury was alleviated by CAR treatment. The results suggest that these beneficial, protective effects are due, at least in part, to its anti-oxidant, anti-inflammatory and anti-fibrotic activities.

    The aim of this study was to investigate the effects curcumin on inflammation and oxidative stress markers in the intestinal ischemia reperfusion (IIR) injury induced rats. Rats were divided into four groups: sham (S), intestinal IR (IIR), curcumin plus sham (CS), and curcumin plus intestinal IR (CIIR). Curcumin was given 200 mg kg⁻¹ for 20 days. IIR was produced by 45 min of intestinal ischemia followed by a 120 min of reperfusion. Although interleukin-6 levels tended to increase in IIR group tumor necrosis factor-α levels were not different. Intestinal myeloperoxidase activity in CS group was lower than IIR group. In intestine and heart tissues, malondialdehyde levels in CS and CIIR groups were lower than S and IIR groups. Superoxide dismutase activity in CIIR group was higher than IIR group in intestine and lung tissues. Curcumin has a protective role against ischemia reperfusion injury.

  20. Diannexin protects against renal ischemia reperfusion injury and targets phosphatidylserines in ischemic tissue.

    Kimberley E Wever

    Full Text Available Renal ischemia/reperfusion injury (IRI frequently complicates shock, renal transplantation and cardiac and aortic surgery, and has prognostic significance. The translocation of phosphatidylserines to cell surfaces is an important pro-inflammatory signal for cell-stress after IRI. We hypothesized that shielding of exposed phosphatidylserines by the annexin A5 (ANXA5 homodimer Diannexin protects against renal IRI. Protective effects of Diannexin on the kidney were studied in a mouse model of mild renal IRI. Diannexin treatment before renal IRI decreased proximal tubule damage and leukocyte influx, decreased transcription and expression of renal injury markers Neutrophil Gelatinase Associated Lipocalin and Kidney Injury Molecule-1 and improved renal function. A mouse model of ischemic hind limb exercise was used to assess Diannexin biodistribution and targeting. When comparing its biodistribution and elimination to ANXA5, Diannexin was found to have a distinct distribution pattern and longer blood half-life. Diannexin targeted specifically to the ischemic muscle and its affinity exceeded that of ANXA5. Targeting of both proteins was inhibited by pre-treatment with unlabeled ANXA5, suggesting that Diannexin targets specifically to ischemic tissues via phosphatidylserine-binding. This study emphasizes the importance of phosphatidylserine translocation in the pathophysiology of IRI. We show for the first time that Diannexin protects against renal IRI, making it a promising therapeutic tool to prevent IRI in a clinical setting. Our results indicate that Diannexin is a potential new imaging agent for the study of phosphatidylserine-exposing organs in vivo.

    Ganoderma mushrooms (Lingzhi in Chinese) have well-documented health benefits. Ganoderma tsugae (G. tsugae), one of the ganoderma species, has been commercially cultivated as a dietary supplement. Because G. tsugae has high antioxidant activity and because oxidative stress is often associated with cardiac injury, we hypothesized that G. tsugae protects against cardiac injury by alleviating oxidative stress. We tested the hypothesis using a work-overload-induced myocardial injury model created by challenging mice with isoproterenol (ISO). Remarkably, oral G. tsugae protected the mice from ISO-induced myocardial injury. Moreover, the triterpenoid fraction of G. tsugae, composed of a mixture of nine structurally related ganoderic acids (GAs), provided cardioprotection by inhibiting the ISO-induced expression of Fas/Fas ligand, oxidative stress, and apoptosis. The antioxidant activity of GAs was tested in cultured cardio-myoblast H9c2 cells against the insult of H₂O₂. GAs dissipated the cellular reactive oxygen species imposed by H₂O₂ and prevented cell death. Our findings uncovered the cardioprotective activity of G. tsugae and identified GAs as the bioactive components against cardiac insults.

    Hyperpermeability is a crux of pathogenesis of sudden lung edema in many pulmooary disorders,espe=cially in acute lung injury and adult respiratory distress syndrome(ARDS). Using our modified method for assessment of pulmonary vascular permeability,we observed the effects of xanthine with xanthine oxi-dase (X-XO) perfused in rat pulmonary artery and the protection of vasoactive intestinal polypeptide (VIP) against the injury of pulmonary vascular permesbility.After addition of xanthine oxidase in the perfusate reservoir containing xanthine,125I-albumin leak index (125IALI) was remarkably increased while peak airway pressure (Paw) was not significantly increased,and perfusion pressure of pulmonary artery (Ppa) and lung wet/dry weight ratio (W/D) were only slightly increased.Xanthine plus xanthine oxi-dase also increased thromboxane B2(TX B2) and 6-keto-prostaglandin F1α(6-keto-PGF1α) in the perfusat-e.Treatment with VIP obviously reduced or totally prevented all signs of injury.Simultaneously,VIP also diminished or abolished the associated generation of arachidonate products.The results indicated that VIP bas potent protective activity against injury of pulmonary vasculat permeability and may be a physiological modulator of inflammatory damage to vaseular eodothelium associated with toxic oxygen metabolites.

    Three children, a 6-year-old boy and two girls aged 5 and 4 years, were seen at an emergency department due to distal lower-leg injuries sustained from the spokes of bicycle wheels. All three patients had been passengers on rear carrying seats of moving bicycles. Only the third bicyclist had used a special child safety seat. The second girl had drawn her foot up from underneath a strap and suffered a tibial fracture later treated with an osteosynthetic plate. The other two patients recovered after conservative casting treatment. Bicycle spoke-related injuries are sustained when the foot or lower limb makes contact with the spokes of a bicycle wheel and usually by children who are bicycle passengers. In the Netherlands, approximately 4600 children are seen at emergency departments with such injuries each year. Bicycle spoke-related accidents can cause severe damage that can result in lengthy recovery periods. Not only physical complications but also psychological ones can occur. The latter are often overlooked but do deserve proper treatment. The physician treating a spoke-related injury is in a good position to advice parents as to preventive measures, particularly on the use of special child safety seats.

    As the leading cause of death and among the top causes of hospitalisation in Canadians aged 1-44 years, injury is a major public health concern. Little is known about whether knowledge, training and understanding of the underlying causes and mechanisms of injury would help with one's own prevention efforts. Based on the Theory of Planned Behaviour, we hypothesised that injury prevention professionals would experience fewer injuries than the general population. An online cross-sectional survey was distributed to Canadian injury prevention practitioners, researchers and policy makers to collect information on medically attended injuries. Relative risk of injury in the past 12 months was calculated by comparing the survey data with injury incidence reported by a comparable subgroup of adults from the (Canadian Community Health Survey (CCHS)) from 2009 to 2010. We had 408 injury prevention professionals complete the survey: 344 (84.5%) women and 63 (15.5%) men. In the previous 12 months, 86 individuals reported experiencing at least one medically attended injury (21,235 people per 100,000 people); with sports being the most common mechanism (41, 33.6%). Fully 84.8% individuals from our sample believed that working in the field had made them more careful. After accounting for age distribution, education level and employment status, injury prevention professionals were 1.69 (95% CI 1.41 to 2.03) times more likely to be injured in the past year. Despite their convictions of increasing their own safety behaviour and that of others, injury prevention professionals' knowledge and training did not help them prevent their own injuries.

    2014-01-01

    Soccer, or football, as it is known in much of the world, is one of the most popular sports in the world. The purpose of this article was to provide a concise update on select soccer-specific medical issues published in the last year as they relate to soccer injury and prevention, concussions, and chronic groin pain. Both the Fédération Internationale de Football Association and the Union of European Football Associations published data from their longstanding injury tracking systems, providing foundation for further research. Concussion research continues to drive much interest, especially as it relates to heading and the controversy of subconcussive trauma. Lastly, our understanding of chronic groin pain continues to be refined as we try to understand the complexity of its pathophysiology and attempt to standardize a multispecialty approach of diagnosis and treatment.

    Individuals' decisions and behaviour can play a critical role in determining both the probability and severity of injury. Behavioural decision research studies peoples' decision-making processes in terms comparable to scientific models of optimal choices, providing a basis for focusing...... interventions on the most critical opportunities to reduce risks. That research often seeks to identify the ‘mental models’ that underlie individuals' interpretations of their circumstances and the outcomes of possible actions. In the context of injury prevention, a mental models approach would ask why people...... and create an expert model of the risk situation, interviewing lay people to elicit their comparable mental models, and developing and evaluating communication interventions designed to close the gaps between lay people and experts. This paper reviews the theory and method behind this research stream...

  7. Pharmacological Strategies to Prevent Contrast-Induced Acute Kidney Injury

    2014-01-01

    Full Text Available Contrast-induced acute kidney injury (CI-AKI is the most common iatrogenic cause of acute kidney injury after intravenous contrast media administration. In general, the incidence of CI-AKI is low in patients with normal renal function. However, the rate is remarkably elevated in patients with preexisting chronic kidney disease, diabetes mellitus, old age, high volume of contrast agent, congestive heart failure, hypotension, anemia, use of nephrotoxic drug, and volume depletion. Consequently, CI-AKI particularly in high risk patients contributes to extended hospitalizations and increases long-term morbidity and mortality. The pathogenesis of CI-AKI involves at least three mechanisms; contrast agents induce renal vasoconstriction, increase of oxygen free radicals through oxidative stress, and direct tubular toxicity. Several strategies to prevent CI-AKI have been evaluated in experimental studies and clinical trials. At present, intravascular volume expansion with either isotonic saline or sodium bicarbonate solutions has provided more consistent positive results and was recommended in the prevention of CI-AKI. However, the proportion of patients with risk still develops CI-AKI. This review critically evaluated the current evidence for pharmacological strategies to prevent CI-AKI in patients with a risk of developing CI-AKI.

    Taurine, an abundant amino acid in the nervous system, is reported to reduce ischemic brain injury in a dose-dependent manner. This study was designed to investigate whether taurine protected the brain against closed head injury (CHI) in rats. Taurine was administered intravenously 30 min after CHI. It was found that taurine lessened body-weight loss and improved neurological functions at 7 days after CHI. Moreover, it lowered brain edema and blood-brain barrier permeability, enhanced activity of superoxide dismutase and the level of glutathione, and reduced levels of malondialdehyde and lactic acid in traumatic tissue 24 h after CHI. In addition, it attenuated neuronal cell death in hippocampal CA1 and CA3 subfields 7 days after CHI. All of these effects were dose dependent. These data demonstrated the dose-dependent protection of taurine against experimental CHI and suggest that taurine treatment might be beneficial in reducing trauma-induced oxidative damage to the brain, thus showing the potential for clinical implications.

    2011-06-01

    The effects of schisandrin B (Sch B) and its analogs on solar irradiation-induced oxidative injury were examined in BJ human fibroblasts. Sch B and schisandrin C (Sch C) increased cellular reduced glutathione (GSH) level and protected against solar irradiation-induced oxidative injury. The photoprotection was paralleled by decreases in the elastases-type protease activity and matrix-metalloproteinases-1 expression in solar-irradiated fibroblasts. The cytochrome P-450-mediated metabolism of Sch B or Sch C caused ROS production. The results suggest that by virtue of its pro-oxidant action and the subsequent glutathione antioxidant response, Sch B or Sch C may offer the prospect of preventing skin photo-aging.

    2014-12-01

    Conclusion: Due to an absence of published literature in Sudan, much of the data have been recorded from paper records and empirical observations. Prehospital care and injury prevention in the Sudan is a recent initiative, but it is developing into a promising model with many opportunities for improvement. This momentum should be nurtured and requires a purposive, collective collaboration to draw a blueprint for a locally relevant, effective and efficient prehospital system in Sudan. It is hoped that this article will highlight and encourage further progress.

  14. Fibronectin-integrin signaling is required for L-glutamine's protection against gut injury.

    Directory of Open Access Journals (Sweden)

    Stefanie Niederlechner

    Full Text Available BACKGROUND: Extracellular matrix (ECM stabilization and fibronectin (FN-Integrin signaling can mediate cellular protection. L-glutamine (GLN is known to prevent apoptosis after injury. However, it is currently unknown if ECM stabilization and FN-Integrin osmosensing pathways are related to GLN's cell protective mechanism in the intestine. METHODS: IEC-6 cells were treated with GLN with or without FN siRNA, integrin inhibitor GRGDSP, control peptide GRGESP or ERK1/2 inhibitors PD98059 and UO126 under basal and stressed conditions. Cell survival measured via MTS assay. Phosphorylated and/or total levels of cleaved caspase-3, cleaved PARP, Bax, Bcl-2, heat shock proteins (HSPs, ERK1/2 and transcription factor HSF-1 assessed via Western blotting. Cell size and F-actin morphology quantified by confocal fluorescence microscopy and intracellular GLN concentration by LC-MS/MS. RESULTS: GLN's prevention of FN degradation after hyperthermia attenuated apoptosis. Additionally, inhibition of FN-Integrin interaction by GRGDSP and ERK1/2 kinase inhibition by PD98059 inhibited GLN's protective effect. GRGDSP attenuated GLN-mediated increases in ERK1/2 phosphorylation and HSF-1 levels. PD98059 and GRGDSP also decreased HSP levels after GLN treatment. Finally, GRGDSP attenuated GLN-mediated increases in cell area size and disrupted F-actin assembly, but had no effect on intracellular GLN concentrations. CONCLUSION: Taken together, this data suggests that prevention of FN degradation and the FN-Integrin signaling play a key role in GLN-mediated cellular protection. GLN's signaling via the FN-Integrin pathway is associated with HSP induction via ERK1/2 and HSF-1 activation leading to reduced apoptosis after gut injury.

    The core value guiding the work of physicians and health workers, including those in Environmental and Occupational Epidemiology and Medicine and Injury Prevention, is to protect the health of the public, especially its most vulnerable individuals. In these fields, we emphasize teaching the use of epidemiology, the core discipline of public health, as a tool for early detection and prevention of disease and injury, as well as an instrument for hypothesis testing. The classic core topics are toxic and physical exposures and their effects, and strategies for their prevention; emerging issues are child labor, mass violence, and democide. In environmental health, students need to be prepared for the reality that the most important and severe problems are often the most difficult to investigate, solve, and evaluate. The following are some recommendations for producing graduates who are effective in protecting communities from environmental hazards and risks: (1) Teach the precautionary principle and its application; (2) Evaluate programs for teaching environmental and occupational health, medicine and epidemiology in schools of public health by their impact on the WHO health indicators and their impact on measures of ecosystem sustainability; (3) Develop problem-oriented projects and give academic credit for projects with definable public health impact and redefine the role of the health officer as the chief resident for Schools of Public Health and Community Medicine; (4) Teach the abuses of child labor and working conditions of women in the workplace and how to prevent the hazards and risks from the more common types of child work; (5) Upgrade teaching of injury prevention and prevention of deaths from external causes; (6) Teach students to recognize the insensitivity of epidemiology as a tool for early detection of true risk; (7) Teach the importance of context in the use of tests of statistical significance; (8) Teach the epidemiologic importance of short latency

  16. Prediction and Prevention of Acute Kidney Injury after Cardiac Surgery

    Su Rin Shin

    2016-01-01

    Full Text Available The incidence of acute kidney injury after cardiac surgery (CS-AKI ranges from 33% to 94% and is associated with a high incidence of morbidity and mortality. The etiology is suggested to be multifactorial and related to almost all aspects of perioperative management. Numerous studies have reported the risk factors and risk scores and novel biomarkers of AKI have been investigated to facilitate the subclinical diagnosis of AKI. Based on the known independent risk factors, many preventive interventions to reduce the risk of CS-AKI have been tested. However, any single preventive intervention did not show a definite and persistent benefit to reduce the incidence of CS-AKI. Goal-directed therapy has been considered to be a preventive strategy with a substantial level of efficacy. Many pharmacologic agents were tested for any benefit to treat or prevent CS-AKI but the results were conflicting and evidences are still lacking. The present review will summarize the current updated evidences about the risk factors and preventive strategies for CS-AKI.

    Asiaticoside (AS), a major triterpenoid saponin component isolated from Centella asiatica, has been described to exhibit antioxidant and anti-inflammatory activities. The present study aimed to determine the protective effects and the underlying mechanisms of AS on septic lung injury induced by cecal ligation and puncture (CLP). Mice were pretreated with the AS (45 mg/kg) or AS as well as GW9662 at 1h before CLP, the survival, lung injury, inflammatory mediators and signaling molecules, and Peroxisome proliferator-activated receptor-γ (PPAR-γ) were determined 24 h after CLP. The results showed that AS significantly decreased CLP-induced the mortality, lung pathological damage, the infiltration of mononuclear, polymorphonuclear (PMN) leucocytes and total proteins. Moreover, AS inhibited CLP-induced the activation of mitogen-activated protein kinases (MAPKs) and nuclear factor-κB (NF-κB), the expression of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) protein in lung tissues, and the production of serum tumor necrosis factor (TNF-α) and interleukin-6 (IL-6). Interestingly, the expression of PPAR-γ protein in lung tissue was up-regulated by AS. Furthermore, GW9662 (the inhibitor of PPAR-γ) significantly reversed these beneficial effects of AS in septic mice. These findings suggest that AS could effectively protect from septic lung injury induced by CLP and the underlying mechanisms might be related to up-regulation of PPAR-γ expression to some extent, which inhibits MAPKs and NF-κB pathway.

    Proanthocyanidin, a grape-seed polyphenol, has been reported to have protective properties against vascular injury and ulcers, preventive effects against atherosclerosis and cancer, and antioxidative effects, such as improving lipid metabolism and slowing aging. However, little has been reported on its antiulcer effects. We aimed to elucidate the antiulcer mechanism of proanthocyanidin. Gravinol, containing 89.3% proanthocyanidin, was used. Proanthocyanidin solution, in distilled water, at 0.002%, 0.02%, 0.2%, or 1%, was given to rats ad libitum for 2 weeks. Distilled water was given to control rats. The effect of proanthocyanidin on gastric mucosal injury was investigated with the water-immersion restraint stress model. The ratios of areas of hemorrhagic erosion were compared as the lesion index. Myeloperoxidase activities were also examined, as an index of tissue injury. Superoxide dismutase activity was measured to examine its antioxidative effect. Furthermore, serum gastrin, somatostatin, histamine, and prostaglandin E(2) levels were measured in this rat model. Proanthocyanidin administration significantly suppressed gastric mucosal injury, induced by water-immersion restraint stress, in a dose-dependent manner. Myeloperoxidase activities were also significantly inhibited, whereas superoxide dismutase activities were significantly stimulated. As to gastrointestinal hormones, the secretion of gastrin, somatostatin, and histamine was significantly inhibited, while prostaglandin E(2) secretion was significantly stimulated. Proanthocyanidin was shown to have a protective effect on the gastric mucosa. The mechanisms underlying the effect of proanthocyanidin were considered to be the following: anti-gastrin and anti-histamine effects to prevent attacks by water-immersion restraint stress, and mucoprotective properties, bestowed by increased prostaglandin and increased superoxide dismutase activities in the gastric mucosa.

    Gentamicin is used clinically against Gram negative bacteria because of its efficacy. However, it causes renal injuries and failure at clinical dosages on account of induced oxidative stress. Fagonia olivieri is used in kidneys, liver, alimentary canal and cardiovascular disorders in local system of medicine in Pakistan. This study evaluates the protective abilities of methanol extract of F. olivieri (FOM) against the liver and renal injuries induced with gentamicin in rat. Sprague-Dawley male rats were treated with gentamicin (80mg/kg) alone or with silymarin (50mg/kg) as standard antioxidant drug. The other groups of rats were treated with gentamicin along with FOM (200mg/kg, 400mg/kg) or FOM (400mg/kg) alone. Effect of FOM was investigated on body weight, urine and serum biochemical markers, enzymatic antioxidants of renal and liver along with histopathological alterations. FOM was investigated by GC-MS for the presence of bioactive constituents. Treatment of FOM to rats ameliorated the gentamicin induced toxicity and increased the percent increase in body weight while decreased the absolute and relative weight of hepatic and kidneys. Gentamicin increased the level of specific gravity, count of RBCs and WBCs, and urobilinogen in urine; and AST, ALT, ALP, LDH, total bilirubin, total cholesterol, triglycerides and LDL in serum. Level of lipid peroxides in terms of thiobarbituric acid reactive substances (TBARS) and DNA damages increased while the GSH contents and activity level of CAT, SOD, GSH-Px and GR decreased with gentamicin in liver and kidney samples. Co-treatment of FOM, dose dependently, alleviated the injuries induced with gentamicin. Histopathological studies of liver and kidneys supported the protective abilities of FOM. GC-MS analysis indicated the presence of various compounds including hexadecanoic acid, 2-methoxy-4-vinylphenol, benzoic acid and thalicpureine in the FOM. Results of the present investigation suggested the protective potential of FOM

    2012-10-01

    Full Text Available Abstract Background Local pulmonary and systemic infections can lead to acute lung injury (ALI. The resulting lung damage can evoke lung failure and multiple organ dysfunction associated with increased mortality. Hydrogen sulfide (H2S appears to represent a new therapeutic approach to ALI. The gas has been shown to mediate potent anti-inflammatory and organ protective effects in vivo. This study was designed to define its potentially protective role in sepsis-induced lung injury. Methods C57BL/6 N mice received lipopolysaccharide (LPS intranasally in the absence or presence of 80 parts per million H2S. After 6 h, acute lung injury was determined by comparative histology. Bronchoalveolar lavage (BAL fluid was analyzed for total protein content and differential cell counting. BAL and serum were further analyzed for interleukin-1β, macrophage inflammatory protein-2, and/or myeloperoxidase glycoprotein levels by enzyme-linked immunosorbent assays. Differences between groups were analyzed by one way analysis of variance. Results Histological analysis revealed that LPS instillation led to increased alveolar wall thickening, cellular infiltration, and to an elevated ALI score. In the presence of H2S these changes were not observed despite LPS treatment. Moreover, neutrophil influx, and pro-inflammatory cytokine release were enhanced in BAL fluid of LPS-treated mice, but comparable to control levels in H2S treated mice. In addition, myeloperoxidase levels were increased in serum after LPS challenge and this was prevented by H2S inhalation. Conclusion Inhalation of hydrogen sulfide protects against LPS-induced acute lung injury by attenuating pro-inflammatory responses.

    To observe the protective effect of salidroside against brain injury in rats exposed to hypobaric hypoxia, and investigate the molecular mechanism of salidroside in the prevention of hypobaric hypoxia-induced brain injury. Rats were placed in experiment module simulating 6000 m altitude to establish acute hypobaric hypoxia-induced brain injury models. Their respiratory frequency was observed and recorded. Cell apoptosis in the hippocampal dentate gyrus (DG) was detected by TUNEL assay; the expressions of Ras homolog family member A (RhoA), phosphorylated extracellular signal-regulated kinase (p-ERK) and phosphorylated c-Jun N-terminal kinase (p-JNK) were detected by Western blotting. After acute exposure to 6000 m altitude, the respiratory frequency of the rats increased remarkably. The simulation of hypobaric hypoxia induced cell apoptosis in hippocampal DG region, and salidroside intervention inhibited the process of cell apoptosis. The expressions of RhoA, p-ERK, p-JNK decreased after hypobaric hypoxia exposure. Salidroside intervention reversed RhoA expression and raised the levels of p-ERK and p-JNK. Acute exposure to hypobaric hypoxia can induce cell apoptosis in rat hippocampal DG, and salidroside can protect the cells from the exposure-induced apoptosis.

    Full Text Available For several years, the National Center for Children's Health and Safety (Beterem has worked on many levels to promote safety and prevent injury of the children in Israel. As part of intervention programs in 20 communities around Israel, this paper describes a 1-year, multidisciplinary, multistrategic childhood safety promotion and injury prevention project. The project took place in the Bedouin city of Rahat in the Southern part of Israel, the Negev, conducted by a local safety coordinator. This specific intervention study took place from March 2003 to March 2004. The main goal was to identify hazards and dangerous obstacles in public places in Rahat, then remove or repair the obstacles found, in order to secure a safe public environment for children. “Obstacle”” was defined as any barrier that could endanger the safety of a child. Ten examples are used to illustrate this applied research project, and 80% of the problems were solved within the project period (time to solve between 1 week to 3 months, depending on various factors. We recommend the involvement of a safety coordinator from the community to focus on safety hazards for children, the use of a documentation diary to log the time frame, and also the use of pictures to illustrate the hazards and the changes, or to use as arguments in the lobbying process.

    As trauma is a public health problem, different programs have been designed to prevent injuries. The aim of this study was to evaluate the effectiveness of an educational model that measures the adolescents' attitudes towards the rules of road safety, alcohol and road accidents in Colombia. A pedagogical model evaluating the effect of road safety education and adolescents' attitudes towards and experiences of alcohol and road accidents in Colombia was created. After the education concluded, this educational process is analyzed by its impact on adolescents' behavior. The educational program included 160 adolescents with the mean age being 17.5 years. The test results indicated that before the educational program 80% of adolescents did not use a safety element when driving, while after the educational program the percentage of no helmet use among adolescents decreased from 72.5% to 24.3% (p = 0.0001) and driving a vehicle under the state of drunkenness from 49.3% to 8.1% (p = 0.0001). An educational model aimed at preventing injuries caused by traffic accidents is shown to be effective in generating changes in adolescents' customs of and attitudes towards alcohol and road safety standards in Colombia.

    psychological symptoms in the study group compared to data from population groups. Activities in daily life were more restricted in the study group. 109 persons were in active employment. The association between the two effect measures improved ergonomic conditions and active employment, and both individual and work-related characteristics was analysed. The odds for improved working conditions were increased where the employer had given an informative injury description in the injury report, probably indicating that an understanding of the mechanisms of injury is a prerequisite for effective prevention. Sick-leaves for more than 6 months during the year following the report had a significant negative association with active employment, whereas male sex and higher education, respectively, had a positive association. The studied musculo-skeletal injuries were associated with a high prevalence of physical and psychological symptoms. Identification and investigation of ergonomic hazards, as appearing in informative reports on the origin of injuries and in inspection notices, seemed to have a positive influence on the process of prevention.

    Cardiovascular disease (CVD) is the leading cause of the death worldwide. An increasing number of studies have found that autophagy is involved in the progression or prevention of CVD. However, the precise mechanism of autophagy in CVD, especially the myocardial ischaemia-reperfusion injury (MI/R injury), is unclear and controversial. Here, we show that the cardiomyocyte-specific disruption of autophagy by conditional knockout of Atg7 leads to severe contractile dysfunction, myofibrillar disarray and vacuolar cardiomyocytes. A negative cytoskeleton organization regulator, CLP36, was found to be accumulated in Atg7-deficient cardiomyocytes. The cardiomyocyte-specific knockout of Atg7 aggravates the MI/R injury with cardiac hypertrophy, contractile dysfunction, myofibrillar disarray and severe cardiac fibrosis, most probably due to CLP36 accumulation in cardiomyocytes. Altogether, this work reveals autophagy may protect cardiomyocytes from the MI/R injury through the clearance of CLP36, and these findings define a novel relationship between autophagy and the regulation of stress fibre in heart.

    Objective: To elucidate the epidemiological characteristics and to define some preventive strategies for fall injury (FI). Methods: The medical records of patients admitted following a fall from a certain height between August 1996and July 1997 were analyzed retrospectively. Results: A total of 138 patients were assessed, with a mortality of 31.2%. The male-to-female ratio was 3.5: 1.The persons between 20 and 59 years old were the main victims (81.8%), of which 52.2% were related with their work altitude. The remaining adults fall because of,accidents in daily life, suicide attempts, drug abuse,alcohol, or criminal behavior. There were significant differences between the death group and the survival group in the Revised Trauma Score (RTS) and the Injury Severity Score (ISS) value (P <0.05 and P <0.01, respectively).Six children fall from balconies, open windows or roofs.There were significant differences for the height of fall and RTS value in aged group than those in children,adolescents, and adults (P <0.001, 0.005, 0.05; and P <0.05, 0.01, 0.05, respectively). The mortality of FI was significantiy correlated to the height of fall (r = 0.897, P <0.005). Conclusions: Male adults are the main victims,especially the workers at high altitudes. The mortality of FI is significantly correlated to the height of fall. The preventive strategies developed through analyzing the risk factors of fall in different age groups might reduce the injuries and deaths following fall.

  12. Novel approaches in astrocytic protection following brain injury

    2015-02-01

    Full Text Available Astrocytes have gained a broad attention in the last years, as they exert multiple functions for brain maintenance and neuronal protection. Astrocytes are metabolic regulators of the brain, important for the preservation of blood–brain barrier characteristics, clearance of toxic substances and generation of antioxidant molecules and growth factors for neurons and other glial cells. For these reasons, the protection of astrocytes has become of primordial importance for the prevention of neuronal death during pathologies such as Parkinson, Alzheimer, Ischemia, and others. Currently, different approaches are being used for the protection of astrocytes diseases, including the use of growth factors, steroid molecules derivatives, mesenchymal stem cell factors, nicotine and others. Moreover, the combined use of experimental approaches with bioinformatics tools such as the ones obtained through system biology has allowed a broader knowledge in astrocytic protection both in normal and pathological conditions. In this work, we highlight some of these recent approaches in astrocytic protection, and how they could be used for the study of restorative therapies for the brain in pathological conditions.

    To describe differences in in-seat behavior observed between individuals with a spinal cord injury (SCI) with and without a history of recurrent pressure injuries. Cross-sectional cohort study. General community. Twenty-nine adults more than 2 years post SCI, who used a wheelchair as their primary mobility device and had the ability to independently perform weight shift maneuvers. Participants were grouped according to whether or not they had a history of recurrent pressure injuries (PrIs), with 12 subjects having had two or more pressure injuries in the pelvic area (PrI Group). Not applicable. Daily time in wheelchair, number of transfers, and frequency of pressure reliefs (full unloading), weight shifts (30% load reduction), and in-seat movements (transient center of pressure movements or unloading). The median participant spent 10.3 hours in his wheelchair and performed 16 transfers to or from the wheelchair daily. Pressure reliefs were performed less than once every 3 hours in both groups. Weight shifts were performed significantly more often by the No PrI Group (median (interquartile range) 2.5 (1.0-3.6) per hour) than the PrI Group (1.0 (0.4-1.9), with P = 0.037 and effect size r = 0.39). In-seat movements were performed 46.5 (28.7-76.7) times per hour by the No PrI group and 39.6 (24.3-49.7) times per hour for the PrI group (P = 0.352, effect size r = 0.17). Weight shifts that can be produced by functional activities and that partially unload the buttocks should be considered as an important addition to individuals' PrI prevention regimen.

  14. Propagation prevention: a complementary mechanism for "lung protective" ventilation in acute respiratory distress syndrome.

    2008-12-01

    To describe the clinical implications of an often neglected mechanism through which localized acute lung injury may be propagated and intensified. Experimental and clinical evidence from the medical literature relevant to the airway propagation hypothesis and its consequences. The diffuse injury that characterizes acute respiratory distress syndrome is often considered a process that begins synchronously throughout the lung, mediated by inhaled or blood-borne noxious agents. Relatively little attention has been paid to possibility that inflammatory lung injury may also begin focally and propagate sequentially via the airway network, proceeding mouth-ward from distal to proximal. Were this true, modifications of ventilatory pattern and position aimed at geographic containment of the injury process could help prevent its generalization and limit disease severity. The purposes of this communication are to call attention to this seldom considered mechanism for extending lung injury that might further justify implementation of low tidal volume/high positive end-expiratory pressure ventilatory strategies for lung protection and to suggest additional therapeutic measures implied by this broadened conceptual paradigm.

    Carbon tetrachloride (CCl(4)) is a well-known hepatotoxicant, and its exposure induces hepatorenal injury via oxidative stress and biochemical alterations. This study had been conducted to confirm the protective role of propolis extract on CCl(4)-induced hepatorenal oxidative stress and resultant injury. Propolis extracts collected from Gwalior district and 24 female Sprague Dawley rats were used for experiment. Animals were exposed to CCl(4) (0.15 mL/kg, i.p.) for 12 weeks (5 days/week) followed by treatment with propolis extract (200 mg/kg, p.o.) for consecutive 2 weeks. CCl(4) exposure significantly depleted blood sugar and hemoglobin level and raised the level of transaminases, alkaline phosphatase, lactate dehydrogenase, protein, urea, albumin, bilirubin, creatinine, triglycerides, and cholesterol in serum. Lipid peroxidation was enhanced, whereas GSH was decreased significantly in liver and kidney in CCl(4)-intoxicated group. Ethanolic extract of propolis successfully prevented these alterations in experimental animals. Activities of catalase, adenosine triphosphatase, glucose-6-phosphatase, acid, and alkaline phosphatase were also maintained towards normal with propolis therapy. Light microscopical studies showed considerable protection in liver and kidney with propolis treatment, thus, substantiated biochemical observations. This study confirmed hepatoprotective potential of propolis extract against chronic injury induced by CCl(4) by regulating antioxidative defense activities.

    Salida Mirzoeva

    Full Text Available The goal of this study was to elucidate the action of the CD28 mimetic peptide p2TA (AB103 that attenuates an excessive inflammatory response in mitigating radiation-induced inflammatory injuries. BALB/c and A/J mice were divided into four groups: Control (C, Peptide (P; 5 mg/kg of p2TA peptide, Radiation (R; total body irradiation with 8 Gy γ-rays, and Radiation + Peptide (RP; irradiation followed by p2TA peptide 24 h later. Gastrointestinal tissue damage was evaluated by analysis of jejunum histopathology and immunohistochemistry for cell proliferation (Cyclin D1 and inflammation (COX-2 markers, as well as the presence of macrophages (F4/80. Pro-inflammatory cytokines IL-6 and KC as well as fibrinogen were quantified in plasma samples obtained from the same mice. Our results demonstrated that administration of p2TA peptide significantly reduced the irradiation-induced increase of IL-6 and fibrinogen in plasma 7 days after exposure. Seven days after total body irradiation with 8 Gy of gamma rays numbers of intestinal crypt cells were reduced and villi were shorter in irradiated animals compared to the controls. The p2TA peptide delivery 24 h after irradiation led to improved morphology of villi and crypts, increased Cyclin D1 expression, decreased COX-2 staining and decreased numbers of macrophages in small intestine of irradiated mice. Our study suggests that attenuation of CD28 signaling is a promising therapeutic approach for mitigation of radiation-induced tissue injury.

    Arsenic (As) tops the ATSDR list of hazardous environmental chemicals and is known to cause liver injury. Although the concentrations of As found in the US water supply are generally too low to directly damage the liver, subhepatotoxic doses of As sensitize the liver to experimental NAFLD. It is now suspected that GI microbiome dysbiosis plays an important role in development of NALFD. Importantly, arsenic has also been shown to alter the microbiome. The purpose of the current study was to test the hypothesis that the prebiotic oligofructose (OFC) protects against enhanced liver injury caused by As in experimental NAFLD. Male C57Bl6/J mice were fed low fat diet (LFD), high fat diet (HFD), or HFD containing oligofructose (OFC) during concomitant exposure to either tap water or As-containing water (4.9 ppm as sodium arsenite) for 10 weeks. HFD significantly increased body mass and caused fatty liver injury, as characterized by an increased liver weight-to-body weight ratio, histologic changes and transaminases. As observed previously, As enhanced HFD-induced liver damage, which was characterized by enhanced inflammation. OFC supplementation protected against the enhanced liver damage caused by As in the presence of HFD. Interestingly, arsenic, HFD and OFC all caused unique changes to the gut flora. These data support previous findings that low concentrations of As enhance liver damage caused by high fat diet. Furthermore, these results indicate that these effects of arsenic may be mediated, at least in part, by GI tract dysbiosis and that prebiotic supplementation may confer significant protective effects. - Highlights: • Arsenic (As) enhances liver damage caused by a high-fat (HFD) diet in mice. • Oligofructose protects against As-enhanced liver damage caused by HFD. • As causes dysbiosis in the GI tract and exacerbates the dysbiosis caused by HFD. • OFC prevents the dysbiosis caused by HFD and As, increasing commensal bacteria.

    Cold injured patients in Alaska come from many sources. Although sport and work continues to provide large numbers of cold injured, most severe repeat injuries tend to reflect other biopsychosocial consequences. Certain behaviors can increase the probability of injury, however all persons living in cold climates are potential candidates. One can decrease risk by education, knowledge and intelligent behavior. Proper respect for adequate protection and hydration seem to be critical factors. Understanding the psychological, physiological and psychophysiological aspects of the cold environment performer helps refine the prevention and treatment strategies for cold injury. Skill training with bio-behavioral methods, such as thermal biofeedback, and the value of medical psychotherapy appear to offer continued promise by facilitating physiologic recovery from injury, as well as assisting in long term rehabilitation. Both approaches increase the likelihood of a favorable healing response by soliciting active patient participation. Medical Psychotherapy for traumatic injuries can also help identify and manage cognitive emotional issues for families and patients faced with the permanent consequences of severe thermal injuries. Thermal biofeedback therapy has the potential benefit of encouraging greater self-reliance and responsibility for self-regulating overall health by integrating self-management skills regarding physiology, diet and lifestyle. Inpatient and outpatient biofeedback training offers specific influence over vascular responses for healing, as well as providing an effective tool for pain management. Interest in cold region habitation has continued to expand our study of human tolerance to harsh, extreme environments. Biological, psychological, sociological, and anthropological views on adaptation, habituation, acclimatization, and injury in cold environments acknowledges the role of development, learning and educated responses to cold environments.

    Etk/Bmx (epithelial and endothelial tyrosine kinase, also known as BMX), a member of the Tec (tyrosine kinase expressed in hepatocellular carcinoma) family of protein-tyrosine kinases, is an important regulator of signal transduction for the activation of cell growth, differentiation, and development. We have previously reported that activation of Etk leads to apoptosis in MDA-MB-468 cells. The purpose of this study was to examine the role of Etk in neuronal injury induced by H(2)O(2) or ischemia. Using Western blot analysis and immunohistochemistry, we found that treatment with H(2)O(2) significantly enhanced phosphorylation of Etk and its downstream signaling molecule Stat1 in primary cortical neurons. Inhibiting Etk activity by LFM-A13 or knocking down Etk expression by a specific shRNA increased the survival of primary cortical neurons. Similarly, at 1 day after a 60-min middle cerebral artery occlusion (MCAo) in adult rats, both phosphorylated Etk and Stat1 were coexpressed with apoptotic markers in neurons in the penumbra. Pretreatment with LFM-A13 or an adenoviral vector encoding the kinase deletion mutant Etkk attenuated caspase-3 activity and infarct volume in ischemic brain. All together, our data suggest that Etk is activated after neuronal injury. Suppressing Etk activity protects against neurodegeneration in ischemic brain.

    In this study, we investigated the potential beneficial effects of quercetin on skeletal muscle ischemia reperfusion injury. Twenty-four Sprague-Dawley type rats were randomly divided into four groups. In the sham group, only gastrocnemius muscle were removed and given no quercetin. In ischemia group, all the femoral artery, vein and collaterals were occluded in the left hindlimb by applying tourniquate under general anaesthesia for three hours but reperfusion was not done. In the Quercetin + Ischemia reperfusion group, quercetin (200 mg kg(-1) dose orally) was given during one-week reoperation and later ischemia reperfusion model was done. Finally, gastrocnemius muscle samples were removed to measure biochemical parameters. The biomarkers, MDA levels, SOD, CAT and GPx activities, were evaluated related to skeletal muscle ischemia reperfusion injury. MDA levels reduced and SOD, CAT and GPx activities increased significantly in Quercetin + Ischemia reperfusion group. Results clearly showed that Quercetin have a protective role against oxidative damage induced by ischemia reperfusion in rats.

    Curcumin can chelate metal ions, forming metallocomplexes. We compared the effects of Zn(II)-curcumin with curcumin against hemorheological alterations, oxidative stress and liver injury in a rat model of acute alcoholism. Oral administration of Zn(II)-curcumin dose-dependently prevented the ethanol-induced elevation of serum malondialdehyde (MDA) content and reductions in glutathione level and superoxide dismutase (SOD) activity. Zn(II)-curcumin also inhibited ethanol-induced liver injury. Additionally, Zn(II)-curcumin dose-dependently inhibited hemorheological abnormalities, including the ethanol-induced elevation of whole blood viscosity, plasma viscosity, blood viscosity at corrected hematocrit (45%), erythrocyte aggregation index, erythrocyte rigidity index and hematocrit. Compared to curcumin at the same dose, Zn(II)-curcumin more effectively elevated SOD activity, ameliorated liver injury and improved hemorheological variables. These results suggest that Zn(II)-curcumin protected the rats from ethanol-induced liver injury and hemorheological abnormalities via the synergistic effect of curcumin and zinc.

    A previous analysis of National Vital Statistics System data for 2003-2007 that examined disparities in rates of motor vehicle-related death by race/ethnicity and sex found that death rates for American Indians/Alaska Natives were two to four times the rates of other races/ethnicities. To address the disparity in motor vehicle-related injuries and deaths among American Indians/Alaska Natives, CDC funded four American Indian tribes during 2004-2009 to tailor, implement, and evaluate evidence-based road safety interventions. During the implementation of these four motor vehicle-related injury prevention pilot programs, seat belt and child safety seat use increased and alcohol-impaired driving decreased. Four American Indian/Alaska Native tribal communities-the Tohono O'odham Nation, the Ho-Chunk Nation, the White Mountain Apache Tribe, and the San Carlos Apache Tribe-implemented evidence-based road safety interventions to reduce motor vehicle-related injuries and deaths. Each community selected interventions from the Guide to Community Preventive Services and implemented them during 2004-2009. Furthermore, each community took a multifaceted approach by incorporating several strategies, such as school and community education programs, media campaigns, and collaborations with law enforcement officers into their programs. Police data and direct observational surveys were the main data sources used to assess results of the programs. Results included increased use of seat belts and child safety seats, increased enforcement of alcohol-impaired driving laws, and decreased motor vehicle crashes involving injuries or deaths. CDC's Office of Minority Health and Health Equity selected the intervention analysis and discussion as an example of a program that might be effective for reducing motor vehicle-related injury disparities in the United States. The Guide to Community Preventive Services recognizes these selected interventions as effective; this report examines the

    There is limited knowledge on epidemiological injury data in judo. To systematically review scientific literature on the frequency and characteristics of injuries in judo. The available literature up to June 2013 was searched for prospective as well as retrospective studies on injuries in judo. Data extraction and presentation focused on the incidence rate, injury risk, types, location and causes of injuries. During the Olympic Games in 2008 and 2012, an average injury risk of about 11-12% has been observed. Sprains, strains and contusions, usually of the knee, shoulder and fingers, were the most frequently reported injuries, whereas being thrown was the most common injury mechanism. Severe injuries were quite rare and usually affected the brain and spine, whereas chronic injuries typically affected the finger joints, lower back and ears. The most common types of injuries in young judo athletes were contusions/abrasions, fractures and sprains/strains. Sex-differences data on judo injuries were mostly inconsistent. Some studies suggested a relationship between nutrition, hydration and/or weight cycling and judo injuries. Also, psychological factors may increase the risk of judo injuries. The present review provides the latest knowledge on the frequency and characteristics of injuries in judo. Comprehensive knowledge about the risk of injury during sport activity and related risk factors represents an essential basis to develop effective strategies for injury prevention. Thus, the introduction of an ongoing injury surveillance system in judo is of utmost importance.

Thus, a study was designed to evaluate coronectomy regarding its use, outcomes and complications.Materials and Methods: A descriptive study was conducted from December 2012 to December 2013 among patients attending Department of Oral and Maxillofacial Surgery, College of Dental Sciences, BP Koirala Institute of Health Sciences, Dharan, Nepal for removal of mandibular third molars. After reviewing the radiograph for proximity of third molar to the IAN, coronectomy was advised. A written informed consent was obtained from the patients and coronectomy was performed. Patients were recalled after one week. The outcome measures in the follow-up visit were primary healing, pain, infection, dry socket, root exposure and IAN injury. The prevalence of IAN proximity of lower third molars and incidence of complications were calculated.Results: A total 300 mandibular third molars were extracted in 278 patients during the study period. Out of 300 impacted mandibular third molar, 41 (13.7% showed close proximity to inferior alveolar nerve . The incidence of complications and failed procedure was 7.4% among the patients who underwent coronectomy. During the follow up visit, persistent pain and root exposure was reported while other complications like inferior alveolar nerve injury, dry socket and infection was not experienced by the study patients.Conclusion: With a success rate of 92.6% among the 41 patients, coronectomy is a viable alternative to conventional total extraction for mandibular third molars who have a higher risk for damage to the inferior alveolar nerve.JCMS Nepal. 2015;11(3:1-5.

    Objective To investigate the protective effect and mechanism of TGF - 1 on intestinal mucosa against ischemia-reperfusion (I/R) injury, so as to provide new methods of clinical prevention from and dealing with intestine I/R injury and gut - derived multiple organ dysfunction syndrome(MODS). Methods 30 SD rats were randomly divided into 3 groups ( n = 10 each), A: namely sham - operation group ( group A) : superior mesenteric artery ( SMA ) was only isolated but not blocked; B: control group (group B), ischemia for 60 minutes, then reperfusion for 120 minutes, and administered with normal saline solution (NS) 0. 5ml through SMA 10 minutes before SMA blockage; C: experimental group (group C) : animals underwent the same procedure with group B except for taking TGF-β1 instead of NS. The contents of intestinal mucosa Chiu's sore, bacteria translocation, intestinal mucosa cellular apoptosis index, expression of bax mRNA and bcl - 2 mRNA and protein were measured. Results Compared with group A, the results from group B are as follows, the Chiu's score significantly increased, bacteria translocation increased, intestinal mucosa cellular apeptosis rate significantly increased, level of bax mRNA and Bax protein significantly increased, while level of intestinal mucosal bcl -2 mRNA and Bcl -2 protein significantly decreased. All the changes in group B were reversed significantly in group C. Conclusion TGF - 1 exerts a protective effect on the gut barrier against intestine I/R injury, perhaps via reversing injury - induced downregulation in bcl2 transcription and upregulation in bax transcription, with the result in modulating bcl -2 and bax protein expression and downregulation of the susceptibility to apoptosis of intestinal epithelial cells.

    Oxidative stress in liver injury is a major pathogenetic factor in the progression of liver damage. Centella asiatica (L.) Urban, known in the United States as Gotu kola, is widely used as a traditional herbal medicine in Chinese or Indian Pennywort. The efficacy of Centella asiatica is comprehensive and is used as an anti-inflammatory agent, for memory improvement, for its antitumor activity and for treatment of gastric ulcers. The present study investigated the protective effects of Centella asiatica on dimethylnitrosamine (DMN)-induced liver injury in rats. The rats in the treatment groups were treated with Centella asiatica at either 100 or 200 mg/kg in distilled water (D.W) or with silymarin (200 mg/kg in D.W) by oral administration for 5 days daily following intraperitoneal injections of 30 mg/kg DMN. Centella asiatica significantly decreased the relative liver weights in the DMN-induced liver injury group, compared with the control. The assessment of liver histology showed that Centella asiatica significantly alleviated mass periportal ± bridging necrosis, intralobular degeneration and focal necrosis, with fibrosis of liver tissues. Additionally, Centella asiatica significantly decreased the level of malondialdehyde, significantly increased the levels of antioxidant enzymes, including superoxide dismutase, glutathione peroxidase and catalase, and may have provided protection against the deleterious effects of reactive oxygen species. In addition, Centella asiatica significantly decreased inflammatory mediators, including interleukin (IL)-1β, IL-2, IL-6, IL-10, IL-12, tumor necrosis factor-α, interferon-γ and granulocyte/macrophage colony-stimulating factor. These results suggested that Centella asiatica had hepatoprotective effects through increasing the levels of antioxidant enzymes and reducing the levels of inflammatory mediators in rats with DMN-induced liver injury. Therefore, Centella asiatica may be useful in preventing liver damage. PMID:27748812

    Training athletes to achieve their personal best is an arduous task. The art of coaching athletes toward world-class performances is a blend of science and psychologic motivation. Competitive athletes train 20 to 40 hours per week and push the physiologic limits of the human body. In the past, applying training loads was a best-guess estimate made by the coach and/or athlete. Every athlete is different, and his or her day-to-day exercise and nonexercise stressors vary greatly. Psychophysiologic disturbances precipitated by overtraining can lead to exponential changes in an athlete's ability to tolerate training loads. Musculoskeletal injuries, neuroendocrine irregularities, immune system suppression, and psychologic problems plague athletes and coaches as they attempt to set world records. This paper provides a framework for physicians, athletes, and coaches to better understand the complexities of training, with hopes of preventing overuse problems.

    Parent education and training programmes can improve maternal psychosocial health, child behavioural problems and parenting practices. This review assesses the effects of parenting interventions for reducing child injury. To assess the effects of parenting interventions for preventing unintentional injury in children aged under 18 years and for increasing possession and use of safety equipment and safety practices by parents. We searched CENTRAL, MEDLINE, EMBASE, BIOSIS Preview, PsycINFO, Sociological Abstracts, Social Science Citation Index, CINAHL, ProQuest Dissertations and Theses, ERIC, DARE, ASSIA, Web of Science, SIGLE and ZETOC. We also handsearched abstracts from the World Conferences on Injury Prevention & Control and the journal Injury Prevention. The searches were conducted in January 2011. We included randomised controlled trials (RCTs), non-randomised controlled trials (non-RCTs) and controlled before and after studies (CBAs), which evaluated parenting interventions administered to parents of children aged 18 years and under, and reported outcome data on injuries for children (unintentional or unspecified intent), possession and use of safety equipment or safety practices (including the Home Observation for Measurement of the Environment (HOME) scale which contained an assessment of home safety) by parents. Parenting interventions were defined as those with a specified protocol, manual or curriculum aimed at changing knowledge, attitudes or skills covering a range of parenting topics. Studies were selected, data were extracted and quality appraised independently by two authors. Pooled relative risks (RR) were estimated using random effect models. Twenty two studies were included in the review: 16 RCTs, two non-RCTs, one partially randomised trial which contained two randomised intervention arms and one non-randomised control arm, two CBA studies and one quasi randomised controlled trial. Seventeen studies provided interventions comprising parenting

    Objective: Hypokalemia is a frequent complication observed after traumatic brain injury (TBI).We evaluated the effect of spironolactone on preventing hypokalemia following moderate to severe TBI.Methods: Patients with moderate to severe TBI, whose Glasgow Coma Scale (GCS) scores of 9-12 and <9,respectively, were equally randomized into intervention and control groups, matching with severity of trauma and baseline serum level of potassium. For the intervention group, we administrated spironolactone (1 mg/kg per day)on the second day of admission or the first day of gavage tolerance and continued it for seven days. No additional intervention was done for controls. Hypokalemia (mild: 3-3.5 mg/L, moderate: 2.5-3 mg/L, and severe: <2.5 mg/L serum K+) and other electrolyte abnormalities were compared between the two groups at the end of the intervention.Results: Sixty-eight patients (58 males and 10 females)were included with mean age=(33.1±11.8) years, and GCS=7.6±2.8. The two groups were similar in baseline characteristics.Patients who received spironolactone were significantly less likely to experience mild, moderate, or severe hypokalemia (8.8%, 2.9%, and 0) compared with controls (29.4%, 11.7%,and 2.9%, respectively, P<0.05). No significant difference was observed between the two groups in the occurrence of other electrolyte abnormalities, hyperglycemia or oliguria.Conclusion: Spironolactone within the first week of head injury could prevent the occurrence of late hypokalemia with no severe side effects.

    Intestinal ischemia/reperfusion (I/R) injury is a grave clinical emergency and associated with high morbidity and mortality rates. Based on the complex underlying mechanisms, a multimodal pharmacological approach seems necessary to prevent intestinal I/R injury. The antibiotic drug doxycycline, which exhibits a wide range of pleiotropic therapeutic properties, might be a promising candidate for also reducing I/R injury in the intestine. To investigate possible protective effects of doxycycline on intestinal I/R injury, human intestinal CaCo-2 cells were exposed to doxycycline at clinically relevant concentrations. In order to mimic I/R injury, CaCo-2 were thereafter subjected to hypoxia/reoxygenation by using our recently described two-enzyme in-vitro hypoxia model. Investigations of cell morphology, cell damage, apoptosis and hydrogen peroxide formation were performed 24h after the hypoxic insult. Hypoxia/reoxygenation injury resulted in morphological signs of cell damage, elevated LDH concentrations in the respective culture media (P<0.001) and increased protein expression of proapoptotic caspase-3 (P<0.05) in the intestinal cultures. These events were associated with increased levels hydrogen peroxide (P<0.001). Preincubation of CaCo-2 cells with different concentrations of doxycycline (5µM, 10µM, 50µM) reduced the hypoxia induced signs of cell damage and LDH release (P<0.001 for all concentrations). The reduction of cellular damage was associated with a reduced expression of caspase-3 (5µM, P<0.01; 10µM, P<0.01; 50µM, P<0.05), while hydrogen peroxide levels remained unchanged. In summary, doxycycline protects human intestinal cells from hypoxia/reoxygenation injury in-vitro. Further animal and clinical studies are required to prove the protective potential of doxycycline on intestinal I/R injury under in-vivo conditions.

    Metabolic activation and oxidant stress are key events in the pathophysiology of acetaminophen (APAP) hepatotoxicity. The initial mitochondrial oxidative stress triggered by protein adduct formation is amplified by c-jun-N-terminal kinase (JNK), resulting in mitochondrial dysfunction and ultimately cell necrosis. Apoptosis signal-regulating kinase 1 (ASK1) is considered the link between oxidant stress and JNK activation. The objective of the current study was to assess the efficacy and mechanism of action of the small-molecule ASK1 inhibitor GS-459679 in a murine model of APAP hepatotoxicity. APAP (300 mg/kg) caused extensive glutathione depletion, JNK activation and translocation to the mitochondria, oxidant stress and liver injury as indicated by plasma ALT activities and area of necrosis over a 24 h observation period. Pretreatment with 30 mg/kg of GS-459679 almost completely prevented JNK activation, oxidant stress and injury without affecting the metabolic activation of APAP. To evaluate the therapeutic potential of GS-459679, mice were treated with APAP and then with the inhibitor. Given 1.5 h after APAP, GS-459679 was still protective, which was paralleled by reduced JNK activation and p-JNK translocation to mitochondria. However, GS-459679 treatment was not more effective than N-acetylcysteine, and the combination of GS-459679 and N-acetylcysteine exhibited similar efficacy as N-acetylcysteine monotherapy, suggesting that GS-459769 and N-acetylcysteine affect the same pathway. Importantly, inhibition of ASK1 did not impair liver regeneration as indicated by PCNA staining. In conclusion, the ASK1 inhibitor GS-459679 protected against APAP toxicity by attenuating JNK activation and oxidant stress in mice and may have therapeutic potential for APAP overdose patients. - Highlights: • Two ASK1 inhibitors protected against acetaminophen-induced liver injury. • The ASK1 inhibitors protect when used as pre- or post-treatment. • Protection by ASK1 inhibitor is

    Activation of the farnesoid X receptor (FXR) has indicated a therapeutic potential for this nuclear bile acid receptor in the prevention of diabetic nephropathy and obesity-induced renal damage. Here, we investigated the protective role of FXR against kidney damage induced by obesity in mice that had undergone uninephrectomy, a model resembling the clinical situation of kidney donation by obese individuals. Mice fed a high-fat diet developed the core features of metabolic syndrome, with subsequent renal lipid accumulation and renal injury, including glomerulosclerosis, interstitial fibrosis, and albuminuria. The effects were accentuated by uninephrectomy. In human renal biopsies, staining of 4-hydroxynonenal (4-HNE), glucose-regulated protein 78 (Grp78), and C/EBP-homologous protein, markers of endoplasmic reticulum stress, was more prominent in the proximal tubules of 15 obese patients compared with 16 non-obese patients. In mice treated with the FXR agonist obeticholic acid, renal injury, renal lipid accumulation, apoptosis, and changes in lipid peroxidation were attenuated. Moreover, disturbed mitochondrial function was ameliorated and the mitochondrial respiratory chain recovered following obeticholic acid treatment. Culturing renal proximal tubular cells with free fatty acid and FXR agonists showed that FXR activation protected cells from free fatty acid-induced oxidative stress and endoplasmic reticulum stress, as denoted by a reduction in the level of reactive oxygen species staining and Grp78 immunostaining, respectively. Several genes involved in glutathione metabolism were induced by FXR activation in the remnant kidney, which was consistent with a decreased glutathione disulfide/glutathione ratio. In summary, FXR activation maintains endogenous glutathione homeostasis and protects the kidney in uninephrectomized mice from obesity-induced injury.

    Acute intestinal ischaemia/reperfusion injury (AII/R) is an adaptive physiologic response during critical illness, involving mesenteric vasoconstriction and hypoperfusion. Prevention of AII/R in high risk patient populations would have a significant impact on morbidity and mortality. The purpose of this study was to investigate the protective effects of VSL#3 probiotic treatment in a murine model of AII/R. Adult 129/SvEv mice were subjected to an experimental AII/R model using superior mesenteric artery occlusion. Animals were pre-treated with either three days or two weeks of VSL#3 probiotics. Local tissue injury markers were assessed by levels of myeloperoxidase and activation of nuclear factor kappa B (NFкB). Systemic and local cytokines, including interleukin (IL)-1β, IL- 10, TNFα, and interferon gamma were measured by ELISA and multiplex fluorescent detection. VSL#3 probiotics reduced local tissue inflammation and injury due to AII/R. A two-week course of VSL#3 was more effective than a shorter three-day course. The reduction in local inflammation from the two-week course of VSL#3 is correlated to a significant reduction in levels of active IL-1β, and tissue levels of myeloperoxidase. Levels of active NFкB were significantly elevated in the vehicle-fed AII/R mice, corroborating with tissue inflammation, which were attenuated by VSL#3 administrations. VSL#3 did not cause any systemic inflammation or lung injury. VSL#3 probiotics are effective in reducing local tissue injury from AII/R by down-regulating pro-inflammatory mediators and immune cell recruitment. This study highlights a potential role for VSL#3 in management of patients at high risk for AII/R.

    During President Carlos Salinas de Gortari`s administration, the environmental protection and pollution prevention programs throughout the country received an unprecedented financial and political support. The administration included from the beginning very aggressive action plans to protect and enhance the environment. To ensure that all these programs were going to be followed, the president instructed the National Commission of Ecology to include these programs within the National Development Plan, under the National Program for Protection of the Environment. The National Development Plan is a constitutional mandate that requires every Federal Government Action Plan to be designed in accordance with it. New national policies were implemented to enforce environmental legislation. Ten new programs to protect endangered species were approved by Congress, 44 national parks were declared under special federal protection, 14 biosphere reserves were established and 9 more were included to protect wildlife. The three largest cities in the country, Mexico City, Monterrey and Guadalajara received special attention in order to design and implement a program to promptly respond to air pollution emergencies. To control and reduce water pollution from mismanagement of untreated sewage in urban areas, financial support was allocated to build and operate water treatment plants.

    Full Text Available Dietary nucleotides play a role in maintaining the immune responses of both animals and humans. Oral administration of nucleic acids from salmon milt have physiological functions in the cellular metabolism, proliferation, differentiation, and apoptosis of human small intestinal epithelial cells. In this study, we examined the effects of DNA-rich nucleic acids prepared from salmon milt (DNSM on the development of liver fibrosis in an in vivo ethanol-carbon tetrachloride cirrhosis model. Plasma aspartate transaminase and alanine transaminase were significantly less active in the DNSM-treated group than in the ethanol plus carbon tetrachloride (CCl4-treated group. Collagen accumulation in the liver and hepatic necrosis were observed histologically in ethanol plus CCl4-treated rats; however, DNSM-treatment fully protected rats against ethanol plus CCl4-induced liver fibrosis and necrosis. Furthermore, we examined whether DNSM had a preventive effect against alcohol-induced liver injury by regulating the cytochrome p450 2E1 (CYP2E1-mediated oxidative stress pathway in an in vivo model. In this model, CYP2E1 activity in ethanol plus CCl4-treated rats increased significantly, but DNSM-treatment suppressed the enzyme’s activity and reduced intracellular thiobarbituric acid reactive substances (TBARS levels. Furthermore, the hepatocytes treated with 100 mM ethanol induced an increase in cell death and were not restored to the control levels when treated with DNSM, suggesting that digestive products of DNSM are effective for the prevention of alcohol-induced liver injury. Deoxyadenosine suppressed the ethanol-induced increase in cell death and increased the activity of alcohol dehydrogenase. These results suggest that DNSM treatment represents a novel tool for the prevention of alcohol-induced liver injury.

  11. Skin protection in the prevention of skin diseases.

    Science.gov (United States)

    Elsner, Peter

    2007-01-01

    Occupational skin diseases comprise a wide spectrum of conditions. Under epidemiological aspects, occupational contact dermatitis that is usually manifested on the hands is the most frequent occupational skin disease with an estimated average incidence rate of 0.7-1.5 cases per 1,000 workers per year. Irritant dermatitis is due to individual susceptibility and the exposure to irritants such as wet work combined with detergents or other hydrophilic irritants or solvents at the workplace. Chronic irritant dermatitis is a risk factor for delayed-type sensitization and subsequently allergic contact dermatitis. It is therefore the prevention of chronic or cumulative irritant dermatitis that is the decisive factor in the prevention of occupational skin disease. Within prevention programs at the workplace, skin protection plays an important, but limited role. Others are technical and organizational means to avoid or reduce skin exposure to irritants and allergens. Educational measures to increase the awareness of workers for workplace hazards and to motivate them to use skin protection measures appropriately are just as important as the careful selection of skin protection materials.

    AIM: To study the preventive effect of hydrotalcite on gastric mucosal injury in rat induced by taurocholate, and to investigate the relationship between the protective mechanism of hydrotalcite and the expression of trefoil factor family 2 (TFF2) mRNA and c-fos protein.METHODS: Forty five male Wistar rats were randomly divided into hydrotalcite group, ranitidine group and control group. Gastric mucosal injury was induced by introgastric acidified taurocholate. OD value of TFF2 mRNA expression in gastric mucous cells was determined by hybridization and computer image analysis system. OD value of c-fos protein expression in gastric mucous cells was measured by immunohistochemistry and computer image analysis system.RESULTS: The gross mucosal injury index in hydrotalcite group was significantly lower than that in ranitidine group and control group (8.60±2.20 vs 16.32±4.27, 29.53±5.39;P<0.05, P<0.01). The expression level of TFF2 mRNA in hydrotalcite group was markedly higher than that in ranitidine group and control group (0.56±0.09 vs 0.30±0.05, 0.28±0.03,P<0.05). The OD value of c-fos protein in hydrotalcite group was higher than that in ranitidine group and control group (0.52±0.07 vs 0.31±0.04, 0.32±0.05, P<0.05).CONCLUSION: Hydrotalcite can protect gastric mucosal injury in rats induced by taurocholate, which may be related to the increased expression of TFF2 and c-fos protein.

    Home healthcare is one of the fastest growing sectors in the United States. Percutaneous injuries from sharp medical devices (sharps) are a source of bloodborne pathogen infections among home healthcare workers and community members. Sharps use and disposal practices in the home are highly variable and there is no comprehensive analysis of the system of sharps procurement, use and disposal in home healthcare. This gap is a barrier to effective public health interventions. The objectives of this study were to i) identify the full range of pathways by which sharps enter and exit the home, stakeholders involved, and barriers for using sharps with injury prevention features; and ii) assess the leverage points for preventive interventions. This study employed qualitative research methods to develop two systems maps of the use of sharps and prevention of sharps injuries in home healthcare. Twenty-six in-depth interview sessions were conducted including home healthcare agency clinicians, public health practitioners, sharps device manufacturers, injury prevention advocates, pharmacists and others. Interview transcripts were audio-recorded and analyzed thematically using NVIVO qualitative research analysis software. Analysis of supporting archival material also was conducted. All findings guided development of the two maps. Sharps enter the home via multiple complex pathways involving home healthcare providers and home users. The providers reported using sharps with injury prevention features. However, home users' sharps seldom had injury prevention features and sharps were commonly re-used for convenience and cost-savings. Improperly discarded sharps present hazards to caregivers, waste handlers, and community members. The most effective intervention potential exists at the beginning of the sharps systems maps where interventions can eliminate or minimize sharps injuries, in particular with needleless treatment methods and sharps with injury prevention features

    Opening of the mitochondrial permeability transition pore (mPTP) appears to be a pivotal event in myocardial ischemia-reperfusion (I/R) injury. Resuscitated cardiac arrest (CA) leads to the post-CA syndrome that encompasses, not only myocardial dysfunction, but also brain injury, failure of other organs (kidney, liver, or lung), and systemic response to I/R. We aimed to determine whether cyclosporine A (CsA) might prevent multiple organ failure following CA through a ubiquitous mPTP inhibition in each distant vital organ. Anesthetized New Zealand White rabbits were subjected to 15 min of CA and 120 min of reperfusion. At the onset of resuscitation, the rabbits received CsA, its non-immunosuppressive derivative NIM811, or vehicle (controls). Survival, hemodynamics, brain damage, organ injuries, and systemic I/R response were analyzed. Fresh mitochondria were isolated from the brain, heart, kidney, liver, and lung to assess both oxidative phosphorylation and permeability transition. CsA analogs significantly improved short-term survival and prevented multiple organ failure, including brain damage and myocardial dysfunction (P ubiquitous mitochondrial protective effect at the level of each major distant organ.

    This study was conducted to describe the epidemiology of childhood bathtub-related injuries and to recommend methods for prevention of bathtub-related slips and falls. A consecutive series of 204 children, who were treated for bathtub-related injuries in a pediatric emergency department during a 3-year period were included in the study. The age range was 4 months to 16 years (mean 3.1, SD 2.8, median 2.8 years). Slips and falls accounted for 82.3% (168/204) of mechanisms of injuries. Lacerations, the most common injury type, accounted for 66.7% (136/204) of cases. The most frequent anatomic location of injury was the head or face (68.1%, 139/204). Adult supervision was present during 84.8% (67/79) of the injuries among children younger than 5 years. Parents changed the bathing environment after the patients' injury in 82.3% (65/79) of cases. Injuries due to slips and falls are the most common type of childhood bathtub-related injury. Increased supervision alone will not be sufficient to prevent these injuries, given that adult supervision is already present in most cases. These injuries are most effectively prevented by passive methods, such as providing an effective slip-resistant bathtub surface. The large number of bathtub-related injuries associated with slips and falls argues for exploring a higher coefficient of friction standard for bathtubs, which may lead to fewer injuries.

    Despite increased knowledge of hamstring muscle injuries, the incidence has not diminished. We now know that not all hamstring injuries are the same and that certain types of injuries require prolonged rehabilitation and return to play. The slow stretch type of injury and injuries involving the central tendon both require longer times to return to play. A number of factors have been proposed as being indicators of time taken to return to play, but the evidence for these is conflicting. Recurr...

  18. The protective effect of Nigella sativa against liver injury: a review

    Directory of Open Access Journals (Sweden)

    Full Text Available Nigella sativa (Family Ranunculaceae is a widely used medicinal plant throughout the world. N. sativa is referred in the Middle East as a part of an overall holistic approach to health. Pharmacological properties of N. sativa including immune stimulant, hypotensive, anti-inflammatory, anti-cancer, antioxidant, hypoglycemic, spasmolytic and bronchodilator have been shown. Reactive oxygen species (ROS and oxidative stress are known as the major causes of many diseases such as liver injury and many substances and drugs can induce oxidative damage by generation of ROS in the body. Many pharmacological properties of N. sativa are known to be attributed to the presence of thymoquinone and its antioxidant effects. Thymoquinone protects liver from injury via different mechanisms including inhibition of iron-dependent lipid peroxidation, elevation in total thiol content and glutathione level, radical scavengering, increasing the activity of quinone reductase, catalase, superoxide dismutase and glutathione transferase, inhibition of NF-κB activity and inhibition of both cyclooxygenase and lipoxygenase. Therefore, this review aimed to highlight the roles of ROS in liver diseases and the mechanisms of N. sativa in prevention of liver injury.

    The aim of this study was to investigate to what extent individual-based extended information given to mothers from city parts of low education can improve precautions taken by them to prevent burn and scald injuries involving young children in the home and further to compare the results with a group of mothers who had not received extended information. This intervention study, with a comparison group, has a quasi-experimental design. Individual-based information, with an empowerment approach, was given to a group of mothers living in two separate areas of a city in southern Sweden with a low level of education. In total, 99 mothers of children under the age of 7 months participated. The mothers were selected through the local child healthcare authorities. Observations were made and bivariate analyses were established. The results showed that the intervention had a significant impact on improving the precautions the participating mothers introduced to protect their children against burn and scald injuries in the home and further, in relation to a comparison group. Through empowerment, workshops, and home visits aimed to increase their consciousness and knowledge, the participating mothers' precautions taken against child injuries in the home improved. It is of great importance that a framework for considering the problem of burn and scald injuries to children is presented from a preventive perspective which, in combination with evidence-based interventions, may enable the creation of injury prevention programmes for implementation by the community health care.

  20. A systematic literature review of the relationship between stretching and athletic injury prevention.

    Lewis, Julia

    2014-01-01

    Athletic-related injuries are a major cause for healthcare visits and financial burden for an otherwise healthy population of adults. The purpose of this article was to investigate the effects of stretching on injury prevention and to determine whether current stretching guidelines are beneficial for athletes. A systematic review of the literature was conducted through searching MEDLINE and CINAHL on topics related to stretching and injury prevention. Current belief is that stretching reduces injury incidence and that it should be performed prior to athletic activities. An examination of 11 articles provided inconclusive outcomes regarding the positive effect of stretching on injury prevention. A sport or activity-specific tailored stretch and warm-up program yielded the best outcomes in relation to preventing injuries. Direct negative effects of stretching were not identified; therefore, the application of stretching should be performed on an individual basis.

    Nonmetabolic effects of intensive insulin therapy in critically ill patients have been reported, but the underlying mechanisms are unclear. This study was designed to test the hypothesis that intensive insulin treatment would attenuate burn-induced acute lung injury by protecting the pulmonary microvascular endothelium. The rat model of burn injury was achieved by exposure to 92°C water for 18 seconds. The rats were randomly allocated into the sham, burn/normal saline (NS), and burn/intensive insulin treatment groups. Blood glucose level was maintained between 5 and 7 mmol/L in rats in the burn/intensive insulin treatment group. Pulmonary injury was assessed by hematoxylin and eosin staining, scanning electron microscopy, bronchoalveolar lavage fluid protein concentrations, the lung wet:dry weight ratio, and lung myeloperoxidase activity. Pulmonary microvascular endothelial cells were examined by transmission electron microscopy. Western blotting was used to determine the protein expression of caspase-3. Intensive insulin treatment markedly attenuated the acute lung injury, revealed by improvements in histological features and significant decreases in bronchoalveolar lavage fluid protein concentrations, pulmonary wet:dry weight ratio, and myeloperoxidase activity at 12 hours after injury (P insulin treatment group when compared with the burn/NS group. Overall, intensive insulin treatment efficiently attenuated pulmonary microvascular endothelial cell dysfunction, decreased cell apoptosis, and inhibited acute lung injury after a burn. These findings may be useful in preventing organ failure after burn injury.

    Pterospartum tridentatum is a Leguminosae that grows spontaneously in Portugal. The flowers are used in popular medicine for the treatment of throat irritation conditions and in herbal mixtures for diabetes. Diabetic vascular complications are due, among other reasons, to increased oxidative stress and for that reason antioxidants are believed to be beneficial for the diabetic patient. The flower water extract of this herbal drug showed dose-dependent protective effect of cultured human endothelial cells against oxidative injury induced by H2O2, at concentrations > or =0.3 mg/ml. This water extract, after liquid-liquid and chromatographic fractionation afforded one new isoflavone (5,5'-dihydroxy-3'-metoxi-isoflavone-7-O-beta-glucoside) and three other known isoflavones (prunetin, genistin and sissotrin). The structural characterisation of isolated compounds was achieved by UV, NMR and MS analysis. The flavonol glycoside isoquercitrin was also identified in the extract by HPLC analysis. Isoquercitrin is one of the active antioxidant principles of the extract since it showed dose-dependent protective effect against oxidative injury at concentrations > or =0.3 mM. Isoflavones were inactive at the same concentrations. The results suggest that the water extract of this herbal drug may prevent or reduce the development of diabetic vascular complications.

    Neuro-axonal injury in the central nervous system (CNS) is one of the major pathological hallmarks of experimental autoimmune encephalomyelitis (EAE), an experimental model of multiple sclerosis (MS). Matrine (MAT), a quinolizidine alkaloid derived from the herb Radix Sophorae Flave, has recently been shown to effectively suppress EAE through an anti-inflammatory mechanism. However, whether MAT can also protect myelin/axons from damage is not known. In the present study we show that, while untreated rats developed severe clinical disease, CNS inflammatory demyelination, and axonal damage, these clinical and pathological signs were significantly reduced by MAT treatment. Consistently, MAT treatment reduced the concentration of myelin basic protein in serum and downregulated expression of β-amyloid (Aβ) and B-site APP cleaving enzyme 1 (BACE-1) in the CNS. Further, the CNS of MAT-treated rats exhibited increased expression of brain-derived neurotrophic factor (BDNF), an important factor for neuronal survival and axonal growth. Together, these results demonstrate that MAT effectively prevented neuro-axonal injury, which can likely be attributed to inhibiting risk factors such as BACE-1 and upregulating neuroprotective factors such as BDNF. We conclude that this novel natural reagent, MAT, which effectively protects neuro-axons from CNS inflammation-induced damage, could be a potential candidate for the treatment of neurodegenerative diseases such as MS.

    Recreational sports injuries are expensive to society. Prevention of such injuries must be a major public health goal. In a previous retrospective study, base sliding was found to be responsible for 71% of recreational softball injuries. Because most injuries occurred during rapid deceleration against stationary bases, quick-release (break-away) bases were evaluated as a means to modify this mechanism of injury. In a prospective study, 633 softball games were played on a break-away base fields and 627 games were played on stationary base fields. Forty-five sliding injuries occurred on the stationary base diamonds (1 injury for every 13.9 games) and only two sliding injuries occurred on the break-away fields (1 injury for every 316.5 games). The medical costs for injuries on the stationary base fields was 79 times greater than that on the break-away fields. In a 1035 game follow-up study performed on all fields equipped with break-away bases, two sliding injuries occurred (1 injury for every 517.5 games). Installing break-away bases in fields used by recreational leagues would achieve a significant reduction of serious softball injuries (98%) and, therefore, should be mandatory. Based on our findings, the Centers for Disease Control has estimated 1.7 million injuries would be prevented nationally per year, saving $2.0 billion per year nationally in acute medical care costs.

    Due to the large number of Road Traffic Injuries (RTIs) in Iran, authorities have implemented a number of policies for the prevention of RTIs. However, a scientific analysis of these policies has thus far been neglected. Therefore, this study was conducted for policy analysis of RTIs prevention in Iran. This qualitative study with a case study approach was conducted in Iran during 2016 in two phases: First, by reviewing literature and documents of the past ten years, policies that have been executed to prevent RTIs in Iran were identified. In the second phase of the study, the identified policies were ranked by prioritization matrices. The two policies with the highest scores were selected. 'Policy triangle framework' was used for Policy analyzing. Stakeholders of these policies (42 people) were interviewed. Data were analyzed manually by implementing Content-Analysis methods. The policies of "pupil liaisons" and "safety belt" were selected for analysis from thirteen potential identified polices. The results of some studies revealed that safety belts had not been properly used in Iran (less than 80%). There was an eight-year hiatus between the approval of the safety belts policy and implementation of this policy. Eight actors were identified for safety belts policy. Lack of diligence in implementation of the policy, failing to pay adequate attention to education and the culture of driving, and failing to select an organization for the implementation of the policy, were identified as the main weaknesses of this policy. For 'pupil liaisons' policy, five actors were identified. Following the implementation of this policy, the number of penalties was reduced (17.9%). Neglecting scientific findings and individual-based nature of the policy were identified as the primary weaknesses of this policy. Taking serious measures to properly execute the policy, educating people, selecting an efficient organization that is responsible for the implementation of the policies, and

    Tempol (TPL) under in vitro conditions reduced the extent of gamma radiation induced membrane lipid peroxidation and disappearance of covalently closed circular form of plasmid pBR322. TPL protected cellular DNA from radiation-induced damage in various tissues under ex vivo and in vivo conditions as evidenced by comet assay. TPL also prevented radiation induced micronuclei formation (in peripheral blood leucocytes) and chromosomal aberrations (in bone marrow cells) in whole body irradiated mice. TPL enhanced the rate of repair of cellular DNA (blood leucocytes and bone marrow cells) damage when administered immediately after radiation exposure as revealed from the increased Cellular DNA Repair Index (CRI). The studies thus provided compelling evidence to reveal the effectiveness of TPL to protect hematopoietic system from radiation injury.

    Propolis is an adhesive substance which is collected and used by honeybees. Propolis is a potent antioxidant and a free radical scavenger. This study was designed to determine whether propolis could protect against dysfunction and oxidative stress induced by methotrexate-induced injury in rat testis. A total of 40 male Wistar albino rats were divided into four groups: group 1 was the untreated control. On the eighth day of the experiment, groups 2 and 3 received single intraperitoneal injections of methotrexate (MTX) at 20mg/kg. Groups 3 and 4 received 100mg/kg/day propolis (by oral gavage) for 15 days by the first day of the experimental protocol. Then the rats were decapitated under anesthesia, and their testes were removed. The histopathological and biochemical analysis along with apoptosis assessment of testis tissues were compared. Immunohistochemical analysis of Heat shock protein-70 (HSP-70) and Proliferating Cell Nuclear Antigen (PCNA) were performed. The phenolic characterization of propolis was performed by Liquid chromatography-mass spectrometry (LC-MS/MS). Methotrexate caused tended to increase in malondialdehyde level and in the number of apoptotic cells; it also caused a decrease in MSTD and JTBS, PCNA and HSP-70 expression and xanthine oxidase levels in group 2. Propolis prevented the rise in malondialdehyde, xanthine oxidase levels and HSP-70 expression and improved testicular morphology and JTBS. It was found that, methorexate gives rise to serious damage in the testes and propolis is a potent antioxidant agent in preventing testicular injury.

  2. Nicotine protects kidney from renal ischemia/reperfusion injury through the cholinergic anti-inflammatory pathway.

    Claude Sadis

    Full Text Available Kidney ischemia/reperfusion injury (I/R is characterized by renal dysfunction and tubular damages resulting from an early activation of innate immunity. Recently, nicotine administration has been shown to be a powerful inhibitor of a variety of innate immune responses, including LPS-induced toxaemia. This cholinergic anti-inflammatory pathway acts via the alpha7 nicotinic acetylcholine receptor (alpha7nAChR. Herein, we tested the potential protective effect of nicotine administration in a mouse model of renal I/R injury induced by bilateral clamping of kidney arteries. Renal function, tubular damages and inflammatory response were compared between control animals and mice receiving nicotine at the time of ischemia. Nicotine pretreatment protected mice from renal dysfunction in a dose-dependent manner and through the alpha7nAChR, as attested by the absence of protection in alpha7nAChR-deficient mice. Additionally, nicotine significantly reduced tubular damages, prevented neutrophil infiltration and decreased productions of the CXC-chemokine KC, TNF-alpha and the proinflammatory high-mobility group box 1 protein. Reduced tubular damage in nicotine pre-treated mice was associated with a decrease in tubular cell apoptosis and proliferative response as attested by the reduction of caspase-3 and Ki67 positive cells, respectively. All together, these data highlight that nicotine exerts a protective anti-inflammatory effect during kidney I/R through the cholinergic alpha7nAChR pathway. In addition, this could provide an opportunity to overcome the effect of surgical cholinergic denervation during kidney transplantation.

    Salmonella enterica subsp. enterica serovar Enteritidis (Salmonella Enteritidis) is the predominant cause of serovar-associated food-borne outbreaks in many countries and causes significant clinical symptoms of liver injury, enteritis, and diarrheal diseases. Saccharomyces boulardii is used in clinical application for prophylaxis and the treatment of a variety of diseases caused by bacterial infection. We used a mouse model of Salmonella Enteritidis infection, which included pretreatment with S. boulardii, to reveal the protection mechanisms of S. boulardii against Salmonella Enteritidis infection, including the translocation of Salmonella Enteritidis to the liver 10 days after Salmonella Enteritidis challenge, and the colonisation of Salmonella Enteritidis and the formation of hepatic tissue lesions in mice after Salmonella Enteritidis challenge on the 10th day. Compared with Salmonella Enteritidis infection in mice, S. boulardii decreased Salmonella Enteritidis translocation to the liver by 96%, and 99% of Salmonella Enteritidis colonised the cecum on the 10th day. Saccharomyces boulardii also abated hepatic tissue injury caused by the infiltration of neutrophilic granulocytes, lymphocytes, and plasmocytes by decreasing the translocation of Salmonella to the liver. These findings demonstrated that S. boulardii is an effective agent in the prevention of the hepatic injury induced by Salmonella Enteritidis infection in a mouse model.

    Early graduate occupational therapists (OTs) and physiotherapists (PTs) are routinely employed in work injury management and prevention in Australia. However, our understanding is limited about employer requirements for early graduates entering the field, and how commencing practitioners manage transition to practice. In addition, employers have expressed concerns anecdotally about the preparedness of early graduates for work injury management and prevention. However, evidence is limited about early gradutate preparedness for the field. The study aimed to develop a detailed qualitative account of the perceptions of employers and early graduates on the attributes required of early graduates in work injury management and prevention, and processes for effective transition to practice in this field. A purposive sample of 12 employers and 12 early graduates in work injury management and prevention participated in semi-structured interviews. Questions to employers focused on recruitment, supervision and readiness for practice. Questions to early graduates focused on challenges in transition and effective learning methods. Transcripts were analysed by Leximancer™ and supported by manual coding and synthesis. Four themes with findings were, 1) 'Job and workplace requirements'; skills required by employers and support needed for early graduates, 2) 'Learning for work injury management and prevention'; options for early graduate development and learning methods early graduates found effective, 3) 'Employer expectations of early graduates in transition to work injury management and prevention', responses to transition; and 4) 'Early graduate perceptions on transition to work injury management and prevention'; early graduates responses to transition. Findings for employers and early graduates were similar to those expected in other areas of practice for OTs and PTs. Work injury management and prevention skills were not expected of early graduates by employers. Employers and

    Full Text Available The mitochondrion is a vital component in cellular energy metabolism and intracellular signaling processes. Mitochondria are involved in a myriad of complex signaling cascades regulating cell death vs. survival. Importantly, mitochondrial dysfunction and the resulting oxidative and nitrosative stress are central in the pathogenesis of numerous human maladies including cardiovascular diseases, neurodegenerative diseases, diabetes, and retinal diseases, many of which are related. This review will examine the emerging understanding of the role of mitochondria in the etiology and progression of cardiovascular diseases and will explore potential therapeutic benefits of targeting the organelle in attenuating the disease process. Indeed, recent advances in mitochondrial biology have led to selective targeting of drugs designed to modulate or manipulate mitochondrial function, to the use of light therapy directed to the mitochondrial function, and to modification of the mitochondrial genome for potential therapeutic benefit. The approach to rationally treat mitochondrial dysfunction could lead to more effective interventions in cardiovascular diseases that to date have remained elusive. The central premise of this review is that if mitochondrial abnormalities contribute to the etiology of cardiovascular diseases (e.g. ischemic heart disease, alleviating the mitochondrial dysfunction will contribute to mitigating the severity or progression of the disease. To this end, this review will provide an overview of our current understanding of mitochondria function in cardiovascular diseases as well as the potential role for targeting mitochondria with potential drugs or other interventions that lead to protection against cell injury.

  7. Aerosolized human extracellular superoxide dismutase prevents hyperoxia-induced lung injury.

    Directory of Open Access Journals (Sweden)

    Chih-Ching Yen

    Full Text Available An important issue in critical care medicine is the identification of ways to protect the lungs from oxygen toxicity and reduce systemic oxidative stress in conditions requiring mechanical ventilation and high levels of oxygen. One way to prevent oxygen toxicity is to augment antioxidant enzyme activity in the respiratory system. The current study investigated the ability of aerosolized extracellular superoxide dismutase (EC-SOD to protect the lungs from hyperoxic injury. Recombinant human EC-SOD (rhEC-SOD was produced from a synthetic cassette constructed in the methylotrophic yeast Pichia pastoris. Female CD-1 mice were exposed in hyperoxia (FiO2>95% to induce lung injury. The therapeutic effects of EC-SOD and copper-zinc SOD (CuZn-SOD via an aerosol delivery system for lung injury and systemic oxidative stress at 24, 48, 72 and 96 h of hyperoxia were measured by bronchoalveolar lavage, wet/dry ratio, lung histology, and 8-oxo-2'-deoxyguanosine (8-oxo-dG in lung and liver tissues. After exposure to hyperoxia, the wet/dry weight ratio remained stable before day 2 but increased significantly after day 3. The levels of oxidative biomarker 8-oxo-dG in the lung and liver were significantly decreased on day 2 (P<0.01 but the marker in the liver increased abruptly after day 3 of hyperoxia when the mortality increased. Treatment with aerosolized rhEC-SOD increased the survival rate at day 3 under hyperoxia to 95.8%, which was significantly higher than that of the control group (57.1%, albumin treated group (33.3%, and CuZn-SOD treated group (75%. The protective effects of EC-SOD against hyperoxia were further confirmed by reduced lung edema and systemic oxidative stress. Aerosolized EC-SOD protected mice against oxygen toxicity and reduced mortality in a hyperoxic model. The results encourage the use of an aerosol therapy with EC-SOD in intensive care units to reduce oxidative injury in patients with severe hypoxemic respiratory failure, including

    Almost one of four Germans is registered in a sports club. Nowadays, sport is acknowledged as an integral component of a healthy lifestyle. Numerous studies provide evidence of the benefits of sports on health. However, about 2 million sports injuries per year diminish the health benefits of sport. (a) Description of the epidemiology of sports injuries in German sports club between 1987 and 2012 and (b) identification of focal areas for the development and implementation of prevention measures. Continuous questionnaire-based injury monitoring of club sports injuries that have been reported to the respective sports insurance. Full survey among selected federal sports associations. Since 1987, a sample of 200,884 sports injuries has been established. About two thirds of the injuries are reported in soccer, handball, basketball, and volleyball, although only one third of all sports club members are registered in these team sports. The number of women's soccer injuries has risen from 7.5 to 15.6 %. Ankle injuries have decreased from 28.7 to 16.9 %. By contrast, the rate of knee injuries has increased from 18.4 to 20.3 %. Days of disability have dropped steadily since the 1990s. Inpatient hospital days have decreased from 10 to 5 days, whereas the share of injuries that needed surgery increased from 30 to 40 %. Team ball sports are still a clear focal area for injury prevention, as participation and injury risk are highest in this group. While the prevention of ankle injuries seems to be headed in the right direction, knee injuries are increasing. As team ball sports become more popular among women, who are more prone to severe knee injuries, prevention programs should be tailored toward the specific situation and needs of the targeted sports participants.

    Acetaminophen (APAP) overdose causes severe and occasionally fatal liver injury. Numerous drugs that attenuate APAP toxicity have been described. However these compounds frequently protect by cytochrome P450 inhibition, thereby preventing the initiating step of toxicity. We have previously shown that pretreatment with allopurinol can effectively protect against APAP toxicity, but the mechanism remains unclear. In the current study, C3HeB/FeJ mice were administered allopurinol 18 h or 1 h prior to an APAP overdose. Administration of allopurinol 18 h prior to APAP overdose resulted in an 88% reduction in liver injury (serum ALT) 6 h after APAP; however, 1 h pretreatment offered no protection. APAP-cysteine adducts and glutathione depletion kinetics were similar with or without allopurinol pretreatment. The phosphorylation and mitochondrial translocation of c-jun-N-terminal-kinase (JNK) have been implicated in the progression of APAP toxicity. In our study we showed equivalent early JNK activation (2 h) however late JNK activation (6 h) was attenuated in allopurinol treated mice, which suggests that later JNK activation is more critical for the toxicity. Additional mice were administered oxypurinol (primary metabolite of allopurinol) 18 h or 1 h pre-APAP, but neither treatment protected. This finding implicated an aldehyde oxidase (AO)-mediated metabolism of allopurinol, so mice were treated with hydralazine to inhibit AO prior to allopurinol/APAP administration, which eliminated the protective effects of allopurinol. We evaluated potential targets of AO-mediated preconditioning and found increased hepatic metallothionein 18 h post-allopurinol. These data show metabolism of allopurinol occurring independent of P450 isoenzymes preconditions the liver and renders the animal less susceptible to an APAP overdose. - Highlights: • 18 h allopurinol pretreatment protects against acetaminophen-induced liver injury. • 1 h allopurinol pretreatment does not protect from APAP

    We studied whether caffeine impairs protection by ischemic preconditioning (IP) in humans. Ischemic preconditioning is critically dependent on adenosine receptor stimulation. We hypothesize that the adenosine receptor antagonist caffeine blocks the protective effect of IP. In vivo ischemia-reperfusion injury was assessed in the thenar muscle by 99mTc-annexin A5 scintigraphy. Forty-two healthy volunteers performed forearm ischemic exercise. In 24 subjects, this was preceded by a stimulus for IP. In a randomized double-blinded design, the subjects received caffeine (4 mg/kg) or saline intravenously before the experiment. At reperfusion, 99mTc-annexin A5 was administered intravenously. Targeting of annexin was quantified by region-of-interest analysis, and expressed as percentage difference between experimental and contralateral hand. In vitro, we assessed recovery of contractile function of human atrial trabeculae, harvested during heart surgery, as functional end point of ischemia-reperfusion injury. Field-stimulated contraction was quantified at baseline and after simulated ischemia-reperfusion, in a paired approach with and without 5 min of IP, in the presence (n=13) or absence (n = 17) of caffeine (10 mg/l). Ischemic preconditioning reduced annexin targeting in the absence of caffeine (from 13 +/- 3% to 7 +/- 1% at 1 h, and from 19 +/- 2% to 9 +/- 3% at 4 h after reperfusion, p = 0.006), but not after caffeine administration (targeting 11 +/- 2% and 16 +/- 3% at 1 and 4 h). In vitro, IP improved post-ischemic functional recovery in the control group, but not in the caffeine group (8 +/- 3% vs. -8 +/- 5%, p=0.003). Caffeine abolishes IP in 2 human models at a dose equivalent to the drinking of 2 to 4 cups of coffee.

    Full Text Available Polydatin, a glucoside of resveratrol, has been reported to possess potent antioxidative effects. In the present study, we aimed to investigate the effects of polydatin in bone marrow-derived mesenchymal stem cells (BMSCs death caused by hydrogen peroxide (H2O2, imitating the microenvironment surrounding transplanted cells in the injured spinal cord in vitro. In our study, MTT results showed that polydatin effectively prevented the decrease of cell viability caused by H2O2. Hochest 33258, Annexin V-PI, and Western blot assay showed H2O2-induced apoptosis in BMSCs, which was attenuated by polydatin. Further studies indicated that polydatin significantly protects BMSCs against apoptosis due to its antioxidative effects and the regulation of Nrf 2/ARE pathway. Taken together, our results indicate that polydatin could be used in combination with BMSCs for the treatment of spinal cord injury by improving the cell survival and oxidative stress microenvironments.

    Previous studies have shown gastroprotective effect of fish oil in several experimental models. However, the mechanisms and active compounds underlying this effect are not fully understood. Fish oil has several components; among them, one of the most studied is docosahexaenoic acid (DHA), which is an omega-3 long-chain polyunsaturated fatty acid. The aim of this study was to examine the gastroprotective effect of DHA as a pure compound in a rat model of indomethacin-induced gastric injury as well as elucidate some of the mechanism(s) behind DHA's gastroprotective effect. Indomethacin was orally administered to induce an acute gastric injury (3, 10 and 30mg/kg). Omeprazol (a proton pump inhibitor, 30mg/kg, p.o.) and DHA (3, 10, 30mg/kg, p.o.) were gavaged 30 and 120min, respectively, before indomethacin insult (30mg/kg p.o.). Three hours after indomethacin administration, rats were sacrificed, gastric injury was evaluated by determining the total damaged area. A sample of gastric tissue was harvested and processed to quantify prostaglandin E(2) (PGE(2)) and leukotriene B(4) (LTB(4)) levels by enzyme-linked immunosorbent assay. Indomethacin produced gastric injury in dose-dependent manner. DHA protected against indomethacin-induced gastric damage, and this effect was comparable with omeprazol's gastroprotective effect. DHA did not reverse the indomethacin-induced reduction of PGE(2) gastric levels. In contrast, DHA partially prevented the indomethacin-induced increase in LTB(4) gastric levels. This is the first report demonstrating DHA's gastroprotective effect as a pure compound. Furthermore, the results reveal that the gastroprotective effect is mediated by a decrease in gastric LTB(4) levels in indomethacin-induced gastric damage.

    Oat contains different components that possess antioxidant properties;no study to date has addressed the antioxidant effect of the extract of oat bran on the cellular level.Therefore,the present study focuses on the investigation of the protective effect of oat bran extract by enzymatic hydrolysates on human dermal fibroblast injury induced by hydrogen peroxide(H2O2).Kjeldahl determination,phenol-sulfuric acid method,and high-performance liquid chromatography(HPLC)analysis indicated that the enzymatic products of oat bran contain a protein amount of 71.93%,of which 97.43% are peptides with a molecular range from 438.56 to 1301.01 Da.Assays for 1,1-diphenyl-2-picrylhydrazyl(DPPH)radical scavenging activity indicate that oat peptide-rich extract has a direct and concentration-dependent antioxidant activity.3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide(MTT)colorimetric assay and the TdT-mediated digoxigenin-dUTP nick-end labeling(TUNEL)assay for apoptosis showed that administration of H2O2 in human dermal fibroblasts caused cell damage and apoptosis.Pre-incubation of human dermal fibroblasts with the Oatp for 24 h markedly inhibited human dermal fibroblast injury induced by H2O2,but application oat peptides with H2O2 at same time did not.Pre-treatment of human dermal fibroblasts with Oatp significantly reversed the H2O2-induced decrease of superoxide dismutase(SOD)and the inhibition of malondialdehyde(MDA).The results demonstrate that oat peptides possess antioxidant activity and are effective against H2O2-induced human dermal fibroblast injury by the enhanced activity of SOD and decrease in MDA level.Our results suggest that oat bran will have the potential to be further explored as an antioxidant functional food in the prevention of aging-related skin injury.

  14. Partial deletion of argininosuccinate synthase protects from pyrazole plus lipopolysaccharide-induced liver injury by decreasing nitrosative stress.

    Argininosuccinate synthase (ASS) is the rate-limiting enzyme in the urea cycle. Along with nitric oxide synthase (NOS)-2, ASS endows cells with the L-citrulline/nitric oxide (NO·) salvage pathway to continually supply L-arginine from L-citrulline for sustained NO· generation. Because of the relevant role of NOS in liver injury, we hypothesized that downregulation of ASS could decrease the availability of intracellular substrate for NO· synthesis by NOS-2 and, hence, decrease liver damage. Previous work demonstrated that pyrazole plus LPS caused significant liver injury involving NO· generation and formation of 3-nitrotyrosine protein adducts; thus, wild-type (WT) and Ass+/- mice (Ass+/+ mice are lethal) were treated with pyrazole plus LPS, and markers of nitrosative stress, as well as liver injury, were analyzed. Partial ablation of Ass protected from pyrazole plus LPS-induced liver injury by decreasing nitrosative stress and hepatic and circulating TNFα. Moreover, apoptosis was prevented, since pyrazole plus LPS-treated Ass+/- mice showed decreased phosphorylation of JNK; increased MAPK phosphatase-1, which is known to deactivate JNK signaling; and lower cleaved caspase-3 than treated WT mice, and this was accompanied by less TdT-mediated dUTP nick end labeling-positive staining. Lastly, hepatic neutrophil accumulation was almost absent in pyrazole plus LPS-treated Ass+/- compared with WT mice. Partial Ass ablation prevents pyrazole plus LPS-mediated liver injury by reducing nitrosative stress, TNFα, apoptosis, and neutrophil infiltration.

    2004-01-01

    The aim of this retrospective study was to determine the effectiveness of a work injury prevention program in the housekeeping department of a hotel. Studies have validated the use of different injury prevention strategies to decrease the incidence of work-related injuries. Few studies, however, have reported the efficacy of an on-site work injury prevention program by a physical therapist. In 1995, implementation of a work injury prevention program by a physical therapist to 50 housekeeping supervisors, 60 house persons and 340 guest room attendants at a large hotel began. This program included a detailed work risk analysis of the work environment, development of job descriptions, identification of injury-related problematic work situations, and implementation of a job specific supervisor-training program. Supervisor, house person and guest room attendant training was also conducted at the end of 1995 and the beginning of 1997. Data of injury reports in 1995, 1996, and 1997 were analyzed to determine the results of the program. There was a reduction in total injury claims, total medical expenses, total lost work time and total restricted duty time. These results demonstrate the cost effectiveness of implementing a work injury prevention program for housekeeping guest room attendants in the hotel industry. Copyright 2004 IOS Press

  16. Anterior cruciate ligament injuries in soccer: Loading mechanisms, risk factors, and prevention programs

    2014-12-01

    Full Text Available Anterior cruciate ligament (ACL injuries are common in soccer. Understanding ACL loading mechanisms and risk factors for ACL injury is critical for designing effective prevention programs. The purpose of this review is to summarize the relevant literature on ACL loading mechanisms, ACL injury risk factors, and current ACL injury prevention programs for soccer players. Literature has shown that tibial anterior translation due to shear force at the proximal end of tibia is the primary ACL loading mechanism. No evidence has been found showing that knee valgus moment is the primary ACL loading mechanism. ACL loading mechanisms are largely ignored in previous studies on risk factors for ACL injury. Identified risk factors have little connections to ACL loading mechanisms. The results of studies on ACL injury prevention programs for soccer players are inconsistent. Current ACL injury prevention programs for soccer players are clinically ineffective due to low compliance. Future studies are urgently needed to identify risk factors for ACL injury in soccer that are connected to ACL loading mechanisms and have cause-and-effect relationships with injury rate, and to develop new prevention programs to improve compliance.

    Full Text Available Contrast-induced AKI (CI-AKI has been one of the leading causes for hospital-acquired AKI and is associated with independent risk for adverse clinical outcomes including morbidity and mortality. The aim of this review is to provide a brief summary of the studies that focus on nonpharmacological strategies to prevent CI-AKI, including routine identification of at-risk patients, use of appropriate hydration regimens, withdrawal of nephrotoxic drugs, selection of low-osmolar contrast media or isoosmolar contrast media, and using the minimum volume of contrast media as possible. There is no need to schedule dialysis in relation to injection of contrast media or injection of contrast agent in relation to dialysis program. Hemodialysis cannot protect the poorly functioning kidney against CI-AKI.

    Cromakalim, an adenosine triphosphate-sensitive potassium channel opener, exhibits protective effects on cerebral ischemia/reperfusion injury. However, there is controversy as to whether this effect is associated with aquaporin-4 and blood-brain barrier permeability. Immunohistochemistry results show that preventive administration of cromakalim decreased aquaporin-4 and IgG protein expression in rats with ischemia/reperfusion injury; it also reduced blood-brain barrier permeability, and alleviated brain edema, ultimately providing neuroprotection.

    RugbySmart, a rugby union injury prevention programme, was launched in New Zealand in 2001. It was compulsory for all coaches and referees to complete RugbySmart requirements annually in order to continue coaching or refereeing. After 5 years of implementation the programme partners, Accident Compensation Corporation and New Zealand Rugby Union, evaluated RugbySmart to determine its effectiveness in reducing injuries. The purpose was to evaluate the effect of RugbySmart on reducing injury rates per 100,000 players and resulting injury prevention behaviours. The RugbySmart programme was associated with a decrease in injury claims per 100,000 players in most areas the programme targeted; the programme had negligible impact on non-targeted injury sites. The decrease in injury claims numbers was supported by results from the player behaviour surveys pre- and post-RugbySmart. There was an increase in safe behaviour in the contact situations of tackle, scrum and ruck technique.

    This prospective study was designed to evaluate whether static stretching can prevent training-related injuries in Japan Ground Self-Defense Force military recruits. A total of 901 recruits between 1996 and 1998 were divided into two groups. Of which, 518 recruits were assigned to the stretching group and practiced static stretching before and after each physical training session. The control subjects (383 recruits in the nonstretching group) did not stretch statically prior to exercise. The static stretching consisted of 18 exercises. We collected injury data from medical records and assessed the incidence and the location of injury. The total injury rate was almost the same between two groups; however, the incidences of muscle/tendon injury and low back pain were significantly lower in the stretching group (p stretching decreased the incidence of muscle-related injuries but did not prevent bone or joint injuries.

  1. [Safety handles for ski sticks to prevent eye, hand and stomach injuries (author's transl)].

    Eye injuries caused by ski stick handles are rare but serious. The material and shape of the handle can be designed to prevent serious injury without adversely affecting function. Even at winter temperatures polyurethane remains moderately malleable and shock-absorbent; it is light, and is a poor heat conductor, so that the hands do not get cold quickly. The end of the handle is 8 cm in diameter; attached to this is an adjustable loop which fits around the hand. The loop opens on impact. It is thus impossible for the orbit to sustain injury and there is less danger to other injury-prone regions of the body such as the neck and stomach. The anatomically designed handles, with wide thumb supports, help prevent hand injuries, and in particular thumb injuries, to a large extent. Such injuries have occurred frequently in the past.

    Objective A general review was made of studies involving: (1) the concept and mechanism of the cholinergic anti-inflammatory pathway (CAP), (2) the important role of inflammatory response in myocardial ischemia reperfusion (I/R)injury and (3) the evidence and mechanisms by which CAP may provide protection against myocardial I/R injury.Data sources The data used in this review were mainly from manuscripts listed in PubMed that were published in English from 1987 to 2009. The search terms were "vagal nerve stimulation", "myocardial ischemia reperfusion injury","nicotine acetylcholine receptor" and "inflammation".Study selection (1) Clinical and experimental evidence that the inflammatory response induced by reperfusion enhances myocardial I/R injury. (2) Clinical and laboratory evidence that the CAP inhibits the inflammation and provides protection against myocardial I/R injury.Results The myocardial I/R injury is really an inflammatory process characterized by recruitment of neutrophils into the ischemic myocardium and excessive production of pro-inflammatory cytokines. Because the CAP can modulate the inflammatory response by decreasing the production and release of pro-inflammatory cytokines, it can provide protection against myocardial I/R injury.Conclusions The CAP can inhibit the inflammatory response induced by reperfusion and protect against myocardial I/R injury. It represents an exciting opportunity to develop new and novel therapeutics to attenuate the myocardial I/R injury.

    Nonalcoholic fatty liver disease (NAFLD) spectrum disorders affect approximately 1 billion individuals worldwide. However, the drivers of progressive steatohepatitis remain incompletely defined. Ketogenesis can dispose of much of the fat that enters the liver, and dysfunction in this pathway could promote the development of NAFLD. Here, we evaluated mice lacking mitochondrial 3-hydroxymethylglutaryl CoA synthase (HMGCS2) to determine the role of ketogenesis in preventing diet-induced steatohepatitis. Antisense oligonucleotide-induced loss of HMGCS2 in chow-fed adult mice caused mild hyperglycemia, increased hepatic gluconeogenesis from pyruvate, and augmented production of hundreds of hepatic metabolites, a suite of which indicated activation of the de novo lipogenesis pathway. High-fat diet feeding of mice with insufficient ketogenesis resulted in extensive hepatocyte injury and inflammation, decreased glycemia, deranged hepatic TCA cycle intermediate concentrations, and impaired hepatic gluconeogenesis due to sequestration of free coenzyme A (CoASH). Supplementation of the CoASH precursors pantothenic acid and cysteine normalized TCA intermediates and gluconeogenesis in the livers of ketogenesis-insufficient animals. Together, these findings indicate that ketogenesis is a critical regulator of hepatic acyl-CoA metabolism, glucose metabolism, and TCA cycle function in the absorptive state and suggest that ketogenesis may modulate fatty liver disease.

    Background: Accurate understanding of complex health data is critical in order to deal with wicked health problems and make timely decisions. Wicked problems refer to ill-structured and dynamic problems that combine multidimensional elements, which often preclude the conventional problem solving approach. This pilot study introduces visual analytics (VA) methods to multi-stakeholder decision-making sessions about child injury prevention; Methods: Inspired by the Delphi method, we introduced a novel methodology-group analytics (GA). GA was pilot-tested to evaluate the impact of collaborative visual analytics on facilitating problem solving and supporting decision-making. We conducted two GA sessions. Collected data included stakeholders' observations, audio and video recordings, questionnaires, and follow up interviews. The GA sessions were analyzed using the Joint Activity Theory protocol analysis methods; Results: The GA methodology triggered the emergence of 'common ground' among stakeholders. This common ground evolved throughout the sessions to enhance stakeholders' verbal and non-verbal communication, as well as coordination of joint activities and ultimately collaboration on problem solving and decision-making; Conclusions: Understanding complex health data is necessary for informed decisions. Equally important, in this case, is the use of the group analytics methodology to achieve 'common ground' among diverse stakeholders about health data and their implications.

For this, we used serum deprivation cell model, glutamate and hydrogen peroxide (H2O2-induced RGC-5 cell death models, and staurosporine-differentiated neuron-like RGC-5 in vitro. We also investigated cell survival of purified primary-cultured RGCs treated with Tet. An in vivo retinal ischemia/reperfusion model was used to examine RGC survival after Tet administration 1 day before ischemia. We found that Tet affected RGC-5 survival in a dose- and time-dependent manner. Compared to dimethyl sulfoxide treatment, Tet increased the numbers of RGC-5 cells by 30% at 72 hours. After 48 hours, Tet protected staurosporine-induced RGC-5 cells from serum deprivation-induced cell death and significantly increased the relative number of cells cultured with 1 mM H2O2 (P<0.01. Several concentrations of Tet significantly prevented 25-mM-glutamate-induced cell death in a dose-dependent manner. Tet also increased primary RGC survival after 72 and 96 hours. Tet administration (10 µM, 2 µL 1 day before retinal ischemia showed RGC layer loss (greater survival, which was less than those in groups with phosphate-buffered saline intravitreal injection plus ischemia in the central (P=0.005, n=6, middle (P=0.018, n=6, and peripheral (P=0.017, n=6 parts of the retina. Thus, Tet conferred protective effects on serum deprivation models of staurosporine-differentiated neuron-like RGC-5 cells and primary cultured murine RGCs. Furthermore, Tet showed

    The study objectives were to examine serious injuries requiring medical attention among children who remain at home after a child welfare/child protective services (CPS) maltreatment investigation in the US and to determine whether child/caregiver characteristics and ongoing CPS involvement are related to injuries requiring medical attention. Using the National Survey of Child and Adolescent Well-being, we analyzed data on the subsample of children who remained at home (N = 3,440). A multivariate logistic regression model included child characteristics, chronic illness and disability in the child, level of CPS involvement, subsequent foster care placement, caregiver characteristics, and caregiver/family psychological variables. Injuries requiring medical attention were identified in 10.6% of the in-home population over a 15-month period, with no differences in rates by age. Children with a chronic medical condition (OR = 2.07; 95% CI, 1.20-3.58) and children with depressed caregivers (OR = 2.28; 95% CI, 1.45-3.58) were more likely to have an injury that required medical care. Older caregivers (>54 years) were less likely (OR = 0.15; 95% CI, 0.03-0.69) to have a child with an injury requiring care. Injuries were not related to further involvement with CPS after the initial maltreatment investigation. Children with chronic medical conditions who remained in their biological homes or whose caregivers were depressed were likely to experience an injury requiring medical attention. Older caregivers were less likely to report a child injury. Extending existing health policies for foster children to children who remain at home following referral to CPS may encourage more comprehensive injury prevention for this population.

    Introduction Due to the large number of Road Traffic Injuries (RTIs) in Iran, authorities have implemented a number of policies for the prevention of RTIs. However, a scientific analysis of these policies has thus far been neglected. Therefore, this study was conducted for policy analysis of RTIs prevention in Iran. Methods This qualitative study with a case study approach was conducted in Iran during 2016 in two phases: First, by reviewing literature and documents of the past ten years, policies that have been executed to prevent RTIs in Iran were identified. In the second phase of the study, the identified policies were ranked by prioritization matrices. The two policies with the highest scores were selected. ‘Policy triangle framework’ was used for Policy analyzing. Stakeholders of these policies (42 people) were interviewed. Data were analyzed manually by implementing Content-Analysis methods. Results The policies of “pupil liaisons” and “safety belt” were selected for analysis from thirteen potential identified polices. The results of some studies revealed that safety belts had not been properly used in Iran (less than 80%). There was an eight-year hiatus between the approval of the safety belts policy and implementation of this policy. Eight actors were identified for safety belts policy. Lack of diligence in implementation of the policy, failing to pay adequate attention to education and the culture of driving, and failing to select an organization for the implementation of the policy, were identified as the main weaknesses of this policy. For ‘pupil liaisons’ policy, five actors were identified. Following the implementation of this policy, the number of penalties was reduced (17.9%). Neglecting scientific findings and individual-based nature of the policy were identified as the primary weaknesses of this policy. Conclusions Taking serious measures to properly execute the policy, educating people, selecting an efficient organization that is

  9. The science of fencing: implications for performance and injury prevention.

    In this review we analyse the data from the literature on fencing with the aim of creating a psychobiological and multi-factorial model of fencing performance. Fencing is an open-skilled combat sport that was admitted to the first modern Olympic Games in Athens (1896). It is mainly practised indoors, with three different weapons: the foil, the sabre and the épée, each contested with different rules. A fencing international tournament may last between 9 and 11 hours. Bouts represent only 18% of total competition time, with an effective fight time of between 17 and 48 minutes. The physical demands of fencing competitions are high, involving the aerobic and anaerobic alactic and lactic metabolisms, and are also affected by age, sex, level of training and technical and tactical models utilized in relation to the adversary. The anthropometrical characteristics of fencers show a typical asymmetry of the limbs as a result of the practice of an asymmetrical sport activity. Fencing produces typical functional asymmetries that emphasize the very high level of specific function, strength and control required in this sport. Moreover, the physical demands of fencing are closely linked to the perceptual and psychological ones, and all are subjected to a continuous succession of changes during the bouts based on the behaviour of the opponent. For this reason it is difficult to identify a significant relationship between any one physiological characteristic and performance, and performance is more likely to be influenced by perceptual and neuro-physiological characteristics. Fencers need to anticipate the opponent and to mask their true intentions with a game of feints and counter-feints, which must be supported by an adequate psycho-physical condition to prevent central and peripheral fatigue. Fencing is not particularly dangerous; however, there is a fine line between a fatal lesion and a simple wound from a broken blade. The suggestions for injury prevention fall into three

    Injury prevention exercise programmes for amateur soccer have gained considerable attention, but little is known about their relevance and adaptability to professional soccer settings. The first aim of this study was to evaluate the delivery and content of injury prevention exercise programmes used by professional youth soccer teams, compared to the industry standard injury prevention exercise programme for soccer, the Fédération Internationale de Football Association's FIFA 11+. The second aim was to document specific challenges to implementing injury prevention exercise programmes in this context. Prospective observational study. The participants were soccer coaches, fitness coaches and physiotherapists (n=18) from four teams in a professional youth soccer academy. Each team's chosen injury prevention exercise programmes were observed weekly across an entire soccer season (160 sessions). The delivery and content of the programmes were documented on a standardised worksheet and compared to the FIFA 11+. Specific implementation challenges were recorded. Fitness coaches were the primary deliverers of injury prevention exercise programmes, with support from physiotherapists. Multiple delivery formats and locations were employed, along with the extensive use of equipment. Across all injury prevention exercise programme sessions, a median of one FIFA 11+ exercise was performed in its original form and a further four in a modified form. Implementation challenges included poor staff communication, competing training priorities and heavy game schedules. Although the basic components of the FIFA 11+ hold relevance for professional youth male teams, the delivery and content of injury prevention exercise programmes require considerable tailoring for this context. Recognising this will inform the development of improved, context-specific injury prevention exercise programmes, along with corresponding strategies to enhance their implementation.

    A pre-shift stretching protocol to reduce employee injuries was initiated at a beverage company and a tin mill in the northeastern United States. The primary goal of this study was to determine the effects of a pre-shift stretching program on work-related musculoskeletal injuries. A secondary goal was to evaluate daily participation compliance during the 90-day program. Data on employee injuries during the stretching program were collected and compared to injury events during the same time period 1 year earlier. Comparison to injury events of the total eligible population during the study time frame was also included. Results of this pilot program in terms of injury rate reduction and participant compliance are promising. Study results may be useful for employers considering implementing similar programs and also suggest the need for further study in this area.

    Physical training for United States military personnel requires a combination of injury prevention and performance optimization to counter unintentional musculoskeletal injuries and maximize warrior capabilities. Determining the most effective activities and tasks to meet these goals requires a systematic, research-based approach that is population specific based on the tasks and demands of the warrior. We have modified the traditional approach to injury prevention to implement a comprehensive injury prevention and performance optimization research program with the 101st Airborne Division (Air Assault) at Ft. Campbell, KY. This is Part I of two papers that presents the research conducted during the first three steps of the program and includes Injury Surveillance, Task and Demand Analysis, and Predictors of Injury and Optimal Performance. Injury surveillance based on a self-report of injuries was collected on all Soldiers participating in the study. Field-based analyses of the tasks and demands of Soldiers performing typical tasks of 101st Soldiers were performed to develop 101st-specific laboratory testing and to assist with the design of the intervention (Eagle Tactical Athlete Program (ETAP)). Laboratory testing of musculoskeletal, biomechanical, physiological, and nutritional characteristics was performed on Soldiers and benchmarked to triathletes to determine predictors of injury and optimal performance and to assist with the design of ETAP. Injury surveillance demonstrated that Soldiers of the 101st are at risk for a wide range of preventable unintentional musculoskeletal injuries during physical training, tactical training, and recreational/sports activities. The field-based analyses provided quantitative data and qualitative information essential to guiding 101st specific laboratory testing and intervention design. Overall the laboratory testing revealed that Soldiers of the 101st would benefit from targeted physical training to meet the specific demands of

  14. Stretching for prevention of Achilles tendon injuries: a review of the literature.

    Professional and recreational athletes commonly perform pre-exercise stretching to prevent musculoskeletal injuries. Little definitive evidence exists that clearly demonstrates the efficacy of stretching in reducing injury. Achilles tendon injuries are among the most common injuries affecting active individuals in the United States today. Clinicians commonly recommend stretching the Achilles tendon without concrete scientific evidence to support such a claim. Few studies have addressed the effect of stretching in Achilles tendon injuries, and it is unclear if the conclusions made for musculoskeletal injuries can be applied to the Achilles tendon. Biomechanical studies of the Achilles tendon and measurements of the tendon's reflex activity have demonstrated possible mechanisms for the potential benefit of stretching, including load-induced hypertrophy and increased tendon tensile strength. Recent prospective studies have contended that reductions in plantarflexor strength and increases in ankle dorsiflexion range of motion from stretching the Achilles tendon may increase the risk of injury. Studies examining stretching in injury prevention, the biomechanical properties of injuries to the Achilles tendon were compiled and reviewed. Although many theories have been published regarding the potential benefits and limitations of stretching, few studies have been able to definitively demonstrate its utility in injury prevention.

    Healthcare professionals prescribe foot orthoses (FOs) for treatment and prevention of lower limb injuries, but previous reviews of the effectiveness of FOs have been inconclusive. We have therefore performed a review emphasizing the magnitude of treatment effects to evaluate the clinical effectiveness of FOs in the treatment and prevention of lower limb injuries.Qualifying studies were mainly controlled trials, but some uncontrolled clinical trials of patients with chronic injuries were analysed separately. Injuries included plantar fasciitis, tibial stress fractures and patellofemoral pain syndrome; these were included because of the large treatment costs for these frequent injuries in New Zealand. Outcomes were pain, comfort, function and injury status. Continuous measures were expressed as standardized differences using baseline between-subject standard deviations, and magnitudes were inferred from the intersection of 90% confidence intervals with thresholds of a modified Cohen scale. Effects based on frequencies were expressed as hazard ratios and their magnitudes were inferred from intersection of confidence intervals with a novel scale of thresholds.The effects of FOs for treatment of pain or injury prevention were mostly trivial. FOs were not effective in treating or preventing patellofemoral pain syndrome. Some studies showed moderate effects for treatment of plantar fasciitis. Only a few studies showed moderate or large beneficial effects of FOs in preventing injuries.Customized semi-rigid FOs have moderate to large beneficial effects in treating and preventing plantar fasciitis and posterior tibial stress fractures, and small to moderate effects in treating patellofemoral pain syndrome. Given the limited randomized controlled trials or clinical controlled trials available for the injuries of interest, it may be that more or less benefit can be derived from the use of FOs, but many studies did not provide enough information for the standardized effect

    @@ Multiple procedures of liver transplantation bring conditions producing cold ischemia-reperfusion (I/R) injury. During cold storage, the graft organ is subjected to cold ischemia, also known as hypoxia injury. After reperfusion, although hypoxic condition has been ameliorated, reoxygenation of the graft liver can produce not only reperfusion injury including generation of oxygen free radical, lipoperoxidation and calcium overload, but also aggravate the hypoxia damage, involving endothelial cell (EC) damage, Kupffer cell (KC) activation, and adherence of neutrophils and platelets to Ecs. Clinically, I/R injury is one of the major problems complicating liver transplantation, and can ultimately result in serious complications such as primary nonfunction and delayed graft function, which may lead to the need of urgent retransplantation. Therefore, the therapeutic strategies of attenuating graft I/R injury are clinically significant and might improve overall graft function and survival.

    Traumatic injury is an important and indiscriminant contributor to mortality. Hypothesizing that outcomes from severe injuries do not vary by demographic factors or socioeconomic status, this research analyzed the relationship between race, ethnicity, injury characteristics, and fatality following hospitalization in Suriname. Data were obtained for all hospital episodes in 2008 from the only hospital within the greater Paramaribo area that provides emergency department services. A logistic regression was used to analyze the subset of 544 non-elderly adult trauma victims to assess the contribution of patient demographics and anatomic injury severity to outcome, which was defined as mortality during acute hospitalization. The specific demographics included were patient age, gender, race, and insurance status. Injury severity was measured using the International Classification Injury Severity Score. The results indicate that age, insurance status, injury type, and injury severity were significant predictors for survival. While the uninsured experienced a higher rate of mortality, the model suggests this result is not due to physiologic reasons but behavioral and socioeconomic. The higher mortality is driven by greater injury severity, which increases not only the mortality rate but also the cost of care. Injury severity itself, independent of all other factors, is the most important contributor. The results suggest that a reduction of 10% in injury severity, around the mean, would reduce the probability of mortality by 70%. This suggests that targeting risk-taking behavior, perhaps relating to compliance with safety practices (e.g. seat belt and helmet laws), driver education, and road safety measures can play important roles in reducing mortality and morbidity from injury in Suriname.

    Lung injury is the most pertinent manifestation of extra-abdominal organ dysfunction in pancreatitis. The propensity of this retroperitoneal inflammatory condition to engender a diffuse and life-threatening lung injury is significant. Approximately one third of patients will develop acute lung injury and acute respiratory distress syndrome, which account for 60% of all deaths within the first week. The variability in the clinical course of pancreatitis renders it a vexing entity and makes demonstration of the efficacy of any specific intervention difficult. The distinct pathologic entity of pancreatitis-associated lung injury is reviewed with a focus on etiology and potential therapeutic maneuvers.

    Full Text Available This study aimed to establish baseline data for injury prevalence,mechanism of injury, injury severity and management of injuries in netball playersin South Africa. A cross sectional descriptive design was employed to collect databy means of a questionnaire in 2010. Participants consisted of 254 netball playerswho participated in a netball tournament. Permission was obtained from all therelevant organizations and informed consent obtained from the participants. Thegeneral injury rate was 61.8% with an injury rate of 1.9 injuries per player forthe past season. The most commonly injured structures were the ankle 37.5 % andthe knee 28.6% with the most common mechanism of injury being landing, 19% and 29% respectively. Of those whosustained injuries, 86 (44% of the injured athletes’ sustained severe injuries, 31(16% sustained moderate injuriesand 78 (40% sustained mild injuries. 67% of players reported they were able to continue with the game and 33%received medical assistance losing game and training time. The most common form of management accessed wasphysiotherapy, which accounted for 31%. It is evident that the ankle and knee injury rates amongst South Africannetball players are high in comparison to other netball playing nations. Injury surveillance is an integral part ofdeveloping preventative measures. The article lays a platform for developing these strategies against the backdrop ofits findings and comparison with other authors.

    To investigate the potential protective effects of captopril, the angiotensin-converting enzyme inhibitor, in diabetic rats exposed to ischaemia/reperfusion (I/R) renal injury. Following successful induction of diabetes, captopril treatment (50 mg/kg/day, p.o.) was applied for 4 weeks, after which bilateral renal ischaemia was induced for 30 min followed by reperfusion for 24 h. Captopril significantly attenuated hyperglycaemia and hypoinsulinaemia in diabetic rats, and significantly reduced the elevations of serum creatinine and aldosterone levels, and renal malondialdehyde, tumour necrosis factor-α and nitric oxide (NO), and prevented the depletion of reduced glutathione caused by I/R in diabetic rats. Histopathological renal tissue damage induced by I/R in diabetic rats was ameliorated by captopril treatment. Immunohistochemical analysis revealed that captopril significantly attenuated the reduction of insulin content in pancreatic islet β-cells, and decreased the I/R-induced expression of inducible NO synthase, nuclear factor-κB, Fas ligand and caspase-3, and increased the expression of survivin and heme oxygenase-1 in the kidney tissue of diabetic rats. Captopril represents a potential candidate to reduce the risk of renal injury induced by ischaemia/reperfusion in type 2 diabetes. © 2012 The Authors. JPP © 2012. Royal Pharmaceutical Society.

    Rotenone, an insecticide of botanical origin, causes toxicity through inhibition of complex I of the respiratory chain in mitochondria. This study was undertaken to determine whether rotenone-induced liver oxidant injury is prevented by erdosteine, a mucolytic agent showing antioxidant properties. There were four groups of Male Wistar Albino rats: group one was untreated as control; the other groups were treated with erdosteine (50 mg/kg per day, orally), rotenone (2.5 mg/mL once and 1 mL/kg per day for 60 days, i.p.) or rotenone plus erdosteine, respectively. Rotenone treatment without erdosteine increased xanthine oxidase (XO) enzyme activity and also increased lipid peroxidation in liver tissue (P erdosteine produced a significant decrease in lipid peroxidation and XO activities in comparison with rotenone group (P Erdosteine treatment with rotenone led to an increase in catalase (CAT) and superoxide dismutase (SOD) activities in comparison with the rotenone group (P erdosteine group, there was a negative correlation between XO activity and NO level in liver tissue (r = -0.833, P erdosteine may be a protective agent for rotenone-induced liver oxidative injury in rats.

    In mammalian tissues, taurine is an important natural component and the most abundant free amino acid in the heart, retina, skeletal muscle, brain, and leukocytes. This study is to examine the taurine's protective effects on neuronal ultrastructure, the function of the mitochondrial respiratory chain complex, and on cerebral blood flow (CBF). The model of traumatic brain injury (TBI) was made for SD rats by a fluid percussion device, with taurine (200 mg/kg) administered by tail intravenous injection once daily for 7 days after TBI. It was found that CBF was improved for both left and right brain at 30 min and 7 days post-injury by taurine. Reaction time was prolonged relative to the TBI-only group. Neuronal damage was prevented by 7 days taurine. Mitochondrial electron transport chain complexes I and II showed greater activity with the taurine group. The improvement by taurine of CBF may alleviate edema and elevation in intracranial pressure. Importantly taurine improved the hypercoagulable state.

    AIM: To observe the protective effect of heat shock protein 72 (HSP 72) induced by pretreatment of doxorubicin (DXR)on long-term cold preservation injury of rat livers.METHODS: Sprague-Dawley rats were administered intravenously DXR at a dose of 1 mg/kg body mass in DXR group and saline in control group. After 48 h, the rat liver was perfused with cold Linger′s and University of Wisconsin (UW) solutions and then was preserved in UW solution at 4 ℃ for 24, 36 and 48 h. AST, ALT, LDH and hyaluronic acid in preservative solution were determined. Routine HE,immunohistochemical staining for HSP 72 and electron microscopic examination of hepatic tissues were performed.RESULTS: After 24, 36 and 48 h, the levels of AST, ALT and hyaluronic acid in preservative solution were significantly higher in control group than in DXR group (P<0.05), while LDH level was not significantly different between the 2 groups (P>0.05). Hepatic tissues in DXR group were morphologically normal and significantly injured in control group. HSP 72was expressed in hepatocytes and sinusoidal endothelial cells in DXR group but not in control group.CONCLUSION: Pretreatment of DXR may extend the time of rat liver cold preservation and keep liver alive. The expression of HSP 72 in liver can prevent hepatocytes and sinusoidal endothelial cells from long-term cold preservation injury.

    Distracted driving, a significant public safety issue, is typically categorized as cell phone use and texting. The increase of distracted driving behavior (DDB) has resulted in an increase in injury and death. The purpose of this study was to identify the frequency and perception of DDB in adults. A 7-question SurveyMonkey questionnaire was distributed to a convenience sample of adults. Standard demographics included age, gender, and highest levels of education. Primary outcome questions were related to frequency of DDB, and overall perceptions specific to distracted driving. Results were compared on the basis of demographics. Chi-square testing and the Kruskal-Wallis analysis of variance were applied, with statistical significance defined as P ≤ .05. There were 1857 respondents to the survey: 1721 were aged 23-64 years (93%); 1511 were women (81%); 1461 had high school education or greater (79%). A total of 168 respondents (9%) reported being involved in a car accident while distracted. The highest reported frequency of DDB included cell phone use (69%), eating/drinking (67%), and reaching for an object in the care (49%). Younger age (18-34 years) and higher level of education (bachelor's degree or greater) were statistically associated with these DDB; gender demonstrated no statistical significance. Text messaging was reported by 538 respondents (29%), with a statistically significant association with age (18-34 years), higher education (bachelor's degree or greater), and gender (males). A total of 1143 respondents (63%) believed that they could drive safely while distracted. This study demonstrates that DDB in adults is not restricted to reading and sending text messages. Moreover, these results indicated that people fail to perceive the dangers inherent in distracted driving. Prevention and outreach education should not be limited to texting and cell phone use but should target all forms of DDB. The age group 18-34 years should be the primary target in the

    Pneumatic nail guns are ubiquitous at residential construction sites across the United States. These tools are noted for the traumatic injuries that can occur from their operation. Different trigger mechanisms on these tools are associated with different levels of risk. Residential building subcontractors and workers, both native-born and immigrant, were brought together in focus groups to discuss their attitudes and beliefs regarding risk factors for nail gun injury as well as barriers to the adoption of safer technology. Participants' comments are organized first by influences on traumatic injury occurrence or prevention and later by sociotechnical system category. Participants attributed influences on injury risk to personal and external causation factors in all sociotechnical system categories; however, participants more frequently described influences on injury prevention as related to workers' behaviors, rather than to external factors. A discussion of these influences with respect to attribution theory and sociotechnical models of injury causation is presented.

    Ischemic acute kidney injury is a serious untreatable condition. Activation of the G protein α12 (Gα12) subunit by reactive oxygen species is a major cause of tissue damage during renal ischemia-reperfusion injury. Kidney injury molecule-1 (KIM-1) is a transmembrane glycoprotein that is highly up-regulated during acute kidney injury, but the physiologic significance of this up-regulation is unclear. Here, we report for the first time that Kim-1 inhibits Gα12 activation and protects mice against renal ischemia-reperfusion injury. We reveal that Kim-1 physically interacts with and inhibits cellular Gα12 activation after inflammatory stimuli, including reactive oxygen species, by blocking GTP binding to Gα12. Compared with Kim-1+/+ mice, Kim-1−/− mice exhibited greater Gα12 and downstream Src activation both in primary tubular epithelial cells after in vitro stimulation with H2O2 and in whole kidneys after unilateral renal artery clamping. Finally, we show that Kim-1–deficient mice had more severe kidney dysfunction and tissue damage after bilateral renal artery clamping, compared with wild-type mice. Our results suggest that KIM-1 is an endogenous protective mechanism against renal ischemia-reperfusion injury through inhibition of Gα12. PMID:25759266

    Local television news is America's primary source of information and may be an opportunity to shape public opinion surrounding issues such as injury prevention. This study sought to systematically evaluate unintentional-injury coverage on local television news and to identify frequently interviewed public-service professionals and factors associated with discussion of risk factors and prevention. Late news broadcasts from 122 local television stations within the U.S. during October 2002 were analyzed. The main outcomes variables were counts of case-injury stories: motor-vehicle crashes, fires, falls, drowning, poisonings, and sports-recreational injuries; identification of interviewed public service professionals; and discussion of risk factors and prevention. Bivariate and mulitvariate analysis was performed to identify predictors of discussion of prevention measures, risk factors, or both. Data were analyzed in Fall 2006. From 2795 broadcasts, 1748 case-injury stories were identified. Fires and motor-vehicle crashes constituted 84% of the case-injury stories. There were 245 case-injury stories containing an interview with a public service professional. Police officers and firefighters accounted for 82% of these interviews. Interviews with police officers and firefighters were independently associated with discussion of risk factors and prevention measures for motor-vehicle crashes (OR=2.49, CI=1.7-3.6) and fires (OR=2.77, CI=1.2-5.9), respectively. Motor-vehicle crashes and fires were the most commonly reported injury topics. Police officers and firefighters were most commonly interviewed and, if interviewed, increased the likelihood that risk factors, prevention measures, or both were discussed. Optimizing the messages delivered by public service professionals through public service professional-level and media-level interventions may be an opportunity for disseminating injury-prevention information to the public and to policymakers, and methods to increase the

    Pressure injuries are a patient safety issue. Despite the suite of prevention strategies, sustained reductions in pressure injury prevalence rates have not been achieved. Generally, nurses are usually responsible for assessing patients' pressure injury risk, and then implementing appropriate prevention strategies. The study aim was to describe five planned and implemented pressure injury prevention strategies (risk assessment, management plan, support surface, repositioning, and education), and determine if a relationship existed between the planning and implementation of support surfaces and regular repositioning. An observational study collecting data using chart audits and semi-structured observations. Data were analysed using descriptive and inferential statistics. This study was set in four medical units across two Australian metropolitan hospitals. The sample comprised adult medical inpatients with reduced mobility. A subsample of participants assessed at pressure injury risk on admission was drawn from this sample. Participants were aged ≥18 years, had a hospital length of stay of ≥3 days prior to recruitment, provided an informed consent, and had reduced mobility. There was suboptimal planning and implementation of pressure injury prevention strategies for the sample and subsample. There was a significant relationship between planned and implemented support surfaces at both hospitals; however, no relationship existed between the planned and implemented of regular repositioning at either site. The planning and implementation of pressure injury strategies is haphazard. Patients received support surfaces; however, gaps exist in pressure injury risk assessment, management planning, regular repositioning, and patient education.

    Low frequency electromagnetic field (LF-EMF) decreases the formation of reactive oxygen species, which are key mediators of ischemia/reperfusion (I/R) injury. Therefore, we hypothesized that the LF-EMF protects contractility of hearts subjected to I/R injury. Isolated rat hearts were subjected to 20 min of global no-flow ischemia, followed by 30 min reperfusion, in the presence or absence of LF-EMF. Coronary flow, heart rate, left ventricular developed pressure (LVDP), and rate pressure product (RPP) were determined for evaluation of heart mechanical function. The activity of cardiac matrix metalloproteinase-2 (MMP-2) and the contents of coronary effluent troponin I (TnI) and interleukin-6 (IL-6) were measured as markers of heart injury. LF-EMF prevented decreased RPP in I/R hearts, while having no effect on coronary flow. In addition, hearts subjected to I/R exhibited significantly increased LVDP when subjected to LF-EMF. Although TnI and IL-6 levels were increased in I/R hearts, their levels returned to baseline aerobic levels in I/R hearts subjected to LF-EMF. The reduced activity of MMP-2 in I/R hearts was reversed in hearts subjected to LF-EMF. The data presented here indicate that acute exposure to LF-EMF protects mechanical function of I/R hearts and reduces I/R injury.

    Our knowledge of sports-related injuries in para-sport is limited and there are no data on how Paralympic athletes themselves perceive an injury. The aim of this qualitative study was to explore Paralympic athletes' perceptions of their experiences of sports-related injuries, risk factors and preventive possibilities. Eighteen Swedish Paralympic athletes with vision impairment, intellectual impairment, spinal cord injury, cerebral palsy, myelomeningocele, dysplasia and neuromuscular disorder, representing 10 different para-sports, were interviewed. The qualitative phenomenographic method was used to interpret the data. The analysis revealed nine categories of perceptions of experiences. The athletes perceived that their impairments were involved in the cause and consequential chains associated with a sports-related injury. Other categories that denoted and described these injuries were: sport overuse, risk behaviour, functional limitations, psychological stressors, the normalised pain, health hazards, individual possibilities to prevent sports-related injuries and unequal prerequisites. This qualitative study revealed that Paralympic athletes' perceptions of their experiences of sports-related injuries are complex and multifactorial, and in several ways differ from able-bodied athletes. This needs to be considered in the sports health and safety work within the Paralympic Movement as well as in the design of future injury surveillance systems and preventive programmes.

    Background Chinese medicine plays an important role in hepatoprotective treatment. This study was conducted to investigate the protective effects of emodin and astragalus polysaccharides (APS) in a rat model of chronic hepatic injury.Methods Chronic hepatic injury was induced by hypodermic injection of an olive oil solution containing 40% carbon tetrachloride (CCI4) twice a week, in addition to a diet of 79.5% maizena, 20% fat, 0.5% cholesterol, and 10% alcohol in the drinking water ad libitum for 12 weeks. Meanwhile, the rats were exposed to different concentrations of emodin (40 mg·kg-1·d-1), APS (200 mg·kg-1·d-1), combination drug (emodin 40 mg.kg-1·d-1 combined with APS 200 mg.kg-1·d-1) and colchicine (0.1 mg·kg-1·d-1) in parallel by oral gavage (once a day for 12 weeks). At the end of 12 weeks, blood serum and liver tissue were taken. Serum was collected to determine the levels of total bilirubin (TBIL), alanine transaminase (ALT),aspartate transaminose (AST), and albumin (ALB). Liver and spleen indexes were assayed, followed by the measurements of the liver associated enzyme superoxide dismutase (SOD) and malondialdehyde (MDA). Histopathological changes were studied using optical microscopy.Results Splenohepatomegalia was alleviated and serum levels of TBIL and ALT were reduced in the groups treated with emodin and APS when compared to the control group. In addition, the ALB level in the APS and combination groups was higher. Similarly, the SOD activity of liver homogenates was significantly higher in the groups treated with emodin and APS, while administration of the herbal derivatives prevented the elevation in MDA levels. Histological analysis showed that the APS and combination groups significantly ameliorated the hepatic injury.Conclusions Co-administration of emodin and APS demonstrated a synergistic action in reducing ALT and restoring ALB in the serum from a rat model of chronic hepatic injury. Emodin and APS may ameliorate the CCI4-induced

    In recent years, increased attention has been paid to injuries occurring in Major League Baseball (MLB) players. Although most of the current orthopedic literature regarding baseball injuries pertains to the shoulder and elbow, lumbar spine injuries are another common reason for time out of play. Back and core injuries may represent as many as 12% of all injuries that result in time out of play from MLB. This high rate of injury is likely related to the critical role that the spine plays in every major baseball-related movement. Linking the upper extremities to the hips and lower extremities, a healthy, strong, and stable spine and core is a prerequisite for performance in all levels of baseball. It has been well documented that baseball players with poor spinal control and stabilization are at increased risk for future injury. Common etiologies of lumbar injuries include stress fractures, muscle injury, annular tears with or without disc herniation, facet joint pain, sacroiliac joint pain, and stenosis. This review discusses the epidemiology of spinal injuries in baseball. Special attention is paid to the role of the spine in baseball-related activities, common injuries, tips for making the correct diagnosis, treatment options, outcomes, rehabilitation, and injury prevention.

    Killing of rat pulmonary artery endothelial cells by activated neutrophils is dependent on generation of hydrogen peroxide and its conversion to a highly toxic radical (presumably the hydroxyl radical) in a ferrous iron-dependent reaction. Glycine (as well as several other amino acids) is capable of inhibiting endothelial cell killing in vitro by either activated neutrophils or reagent hydrogen peroxide. Inhibition of killing is enhanced in the presence of micromolar concentrations of manganous ion (Mn2+). The combined effects of glycine and Mn2+ require concomitant presence of bicarbonate ion and is inhibited by high phosphate levels. Glycine can also protect endothelial cells from lethal injury inducted by ionomycin. There appears to be no enhancement with Mn2+, however against this form of lethal injury. The protective effects of glycine, Mn2+ and bicarbonate ion against injury by hydrogen peroxide is associated with a direct disproportionation of the hydrogen peroxide to water with little generation of molecular oxygen. Either glycine or Mn2+ alone does not have this effect. In addition to protecting endothelial cells from hydrogen peroxide-mediated injury, glycine or MN2+ is almost completely protective. Additionally, treatment of rats with concentrations of EDTA that do not by themselves induce injury greatly accentuates lung injury induced by glucose oxidase. These findings suggest that circulating amino acids in combination with Mn2+ and bicarbonate ions may contribute to the normal anti-oxidant barrier. These findings may also form the basis for a possible new therapeutic approach to oxygen radical-mediated injury.

    Metabolic activation and oxidant stress are key events in the pathophysiology of acetaminophen (APAP) hepatotoxicity. The initial mitochondrial oxidative stress triggered by protein adduct formation is amplified by c-jun-N-terminal kinase (JNK), resulting in mitochondrial dysfunction and ultimately cell necrosis. Apoptosis signal-regulating kinase 1 (ASK1) is considered the link between oxidant stress and JNK activation. The objective of the current study was to assess the efficacy and mechanism of action of the small-molecule ASK1 inhibitor GS-459679 in a murine model of APAP hepatotoxicity. APAP (300 mg/kg) caused extensive glutathione depletion, JNK activation and translocation to the mitochondria, oxidant stress and liver injury as indicated by plasma ALT activities and area of necrosis over a 24h observation period. Pretreatment with 30 mg/kg of GS-459679 almost completely prevented JNK activation, oxidant stress and injury without affected the metabolic activation of APAP. To evaluate the therapeutic potential of GS-459679, mice were treated with APAP and then with the inhibitor. Given 1.5h after APAP, GS-459679 was still protective, which was paralleled by reduced JNK activation and p-JNK translocation to mitochondria. However, GS-459679 treatment was not more effective than N-acetylcysteine, and the combination of GS-459679 and N-acetylcysteine exhibited similar efficacy as N-acetylcysteine monotherapy, suggesting that GS-459769 and N-acetylcysteine affect the same pathway. Importantly, inhibition of ASK1 did not impair liver regeneration as indicated by PCNA staining. In conclusion, the ASK1 inhibitor GS-459679 protected against APAP toxicity by attenuating JNK activation and oxidant stress in mice and may have therapeutic potential for APAP overdose patients.

    This report examines associations between injuries and flexibility, stretching, warm-up, and body composition. Military studies show that either too much or too little flexibility increases injury risk. Static stretching prior to exercise does not appear to reduce the overall injury incidence, although further research is needed on some types of injuries. Static stretching also appears to reduce strength and power (explosive strength). Warm-up (low intensity activity prior to exercise or sports) appears to reduce injury risk. Body mass index (BMI; weight in kg/ height in m²) is a surrogate measure of body fat because it is highly related to laboratory measures of body fat. However, Soldiers can also have a high BMI because of higher muscle mass. If high BMI reflects a larger percentage of body fat relative to height, injury risk might be increased because the additional fat would increase the intensity of physical activity, leading to more rapid fatigue and repetitive stress on the musculoskeletal system. Low BMI could reflect a paucity of fat or muscle/ bone, or both. Low BMI may make Soldiers more susceptible to injury if they lack the muscle mass or strength in the supportive structures (ligaments, bones) required to perform certain physical tasks, and if they overexert or overuse the available muscle mass or supportive structures. Studies in basic combat training show that both high and low BMI increases injury risk. However, studies among active duty Soldiers only show that injury risk increases as BMI increases, possibly because very few active duty Soldiers have very low BMI (i.e., less than 18 kg/m²).

    Traumatic brain injury (TBI) can have long term effects on mental and physical health, and can disrupt vocational, educational, and social functioning. TBIs can range from mild to severe and their effects can last many years after the initial injury. CDC seeks to reduce the burden of TBI from unintentional injuries through a focus on primary prevention, improved recognition and management, and intervening to improve health outcomes after TBI. CDC uses a 4-stage public health model to guide TBI prevention, moving from 1) surveillance of TBI, 2) identification of risk and protective factors for TBI, 3) development and testing of evidence-based interventions, to 4) bringing effective intervention to scale through widespread adoption. CDC's unintentional injury prevention activities focus on the prevention of sports-related concussions, motor vehicle crashes, and older adult falls. For concussion prevention, CDC developed Heads Up - an awareness initiative focusing on ways to prevent a concussion in sports, and identifying how to recognize and manage potential concussions. In motor vehicle injury prevention, CDC has developed a tool (MV PICCS) to calculate the expected number of injuries prevented and lives saved using various evidence-based motor vehicle crash prevention strategies. To help prevent TBI related to older adult falls, CDC has developed STEADI, an initiative to help primary care providers identify their patients' falls risk and provide effective interventions. In the future, CDC is focused on advancing our understanding of the public health burden of TBI through improved surveillance in order to produce more comprehensive estimates of the public health burden of TBI.

  11. Remote ischemic preconditioning protects against liver ischemia-reperfusion injury via heme oxygenase-1-induced autophagy.

    Full Text Available BACKGROUND: Growing evidence has linked autophagy to a protective role of preconditioning in liver ischemia/reperfusion (IR. Heme oxygenase-1 (HO-1 is essential in limiting inflammation and preventing the apoptotic response to IR. We previously demonstrated that HO-1 is up-regulated in liver graft after remote ischemic preconditioning (RIPC. The aim of this study was to confirm that RIPC protects against IR via HO-1-mediated autophagy. METHODS: RIPC was performed with regional ischemia of limbs before liver ischemia, and HO-1 activity was inhibited pre-operation. Autophagy was assessed by the expression of light chain 3-II (LC3-II. The HO-1/extracellular signal-related kinase (ERK/p38/mitogen-activated protein kinase (MAPK pathway was detected in an autophagy model and mineral oil-induced IR in vitro. RESULTS: In liver IR, the expression of LC3-II peaked 12-24 h after IR, and the ultrastructure revealed abundant autophagosomes in hepatocytes after IR. Autophagy was inhibited when HO-1 was inactivated, which we believe resulted in the aggravation of liver IR injury (IRI in vivo. Hemin-induced autophagy also protected rat hepatocytes from IRI in vitro, which was abrogated by HO-1 siRNA. Phosphorylation of p38-MAPK and ERK1/2 was up-regulated in hemin-pretreated liver cells and down-regulated after treatment with HO-1 siRNA. CONCLUSIONS: RIPC may protect the liver from IRI by induction of HO-1/p38-MAPK-dependent autophagy.

    Hurling is an Irish national game of stick and ball known for its ferocity, played by 190 000 players. Facial injuries were common but have been significantly reduced by legislation enforcing compulsory helmet wearing. Current standard helmets worn by hurlers do not offer protection to the external ear. Here we describe an emerging pattern of ear injuries and demonstrate the risk of external ear injuries in hurlers complying with current helmet safety standards. A 6-month retrospective analysis was carried out of patients attending Cork University Hospital (CUH) with ear lacerations sustained while hurling. Patient notes were reviewed and helmet manufacturers were interviewed. Seven patients were identified, all of whom sustained complex through ear lacerations while wearing helmets complying with current safety standards. Current helmet design fails to protect the external ear placing it at an increased risk of injury, a potential solution is to include ear protection in the helmet design.

    The anatomical position of the inferior epigastric artery (IEA) subjects it to risk of injury during abdominal procedures that are close to the artery, such as laparoscopic trocar insertion, insertion of intra-abdominal drains, Tenckhoff(®) catheter (peritoneal dialysis catheter) and paracentesis. This article aims to raise the awareness of the anatomical variations of the course of the IEA in relation to abdominal landmarks in order to define a safer zone for laparoscopic ancillary trocar placement. Methods of managing the IEA injury as well as techniques to minimise the risk of injury to the IEA are reviewed and discussed.

    The present study investigated the transcontextual process of motivation in sport injury prevention. We examined whether general causality orientation, perceived autonomy support from coaches (PAS), self-determined motivation (SD-Mtv), and basic need satisfaction in a sport context predicted SD-Mtv, beliefs, and adherence with respect to sport injury prevention. Elite athletes (N = 533) completed self-report measures of the predictors (Week 1) and the dependent variables (Week 2). Variance-based structural equation modeling supported hypotheses: SD-Mtv in a sport context was significantly predicted by PAS and basic need satisfaction and was positively associated with SD-Mtv for sport injury prevention when controlling for general causality orientation. SD-Mtv for sport injury prevention was a significant predictor of adherence to injury-preventive behaviors and beliefs regarding safety in sport. In conclusion, the transcontextual mechanism of motivation may explain the process by which distal motivational factors in sport direct the formation of proximal motivation, beliefs, and behaviors of sport injury prevention.

    The aim of this study was to evaluate the occurrence of dental and facial injuries, the habit of wearing mouthguard and the awareness regarding injury prevention and first aid after tooth avulsion among young taekwondo athletes in Croatia. A survey on a sample of 484 taekwondo athletes was conducted, which included 271 male (56%) and 213 female (44%) athletes aged between 8 and 28 years. The questionnaire submitted to the athletes contained 15 questions about dental trauma, use of mouthguard, dental trauma prevention, level of awareness about tooth avulsion and replantation and disturbances associated with mouthguard use. Collected data were evaluated according to gender, age groups and duration of actively engagement in taekwondo. Descriptive statistics and Chi-square tests were used for comparisons between groups. From the survey 300 (62%) of 484 athletes had sustained one serious injury and 103 (21%) had sustained an orofacial injury, while 194 (40%) had observed another player sustaining a dental injury. Higher number of orofacial injuries was observed in males (24%) than in females (18%). Furthermore, 98 (20%) athletes have experienced one or more dental injuries, and out of these 98 suffering dental injury 60 were male (61%) and 38 were female (39%). The frequency of orofacial injuries in the older group (42%) is higher than in three younger groups (younger cadets 25%; cadets 13%; juniors 20%) (pinjury prevention in taekwondo. The results of this survey show that dental and orofacial injuries occur in taekwondo in all age groups but mostly in the senior group. Taekwondo players know the importance of mouthguard use, but only 5% use custom made mouthguards. This is not adequate for dental injury prevention and highlights the important role of dental professional in education of athletes for advocating the use of custom made mouthguards.

    In this study, we investigated the inhibitory activities on gastritis and gastric ulcer using liriodendrin which is a constituent isolated from Kalopanax pictus. To elucidate its abilities to prevent gastric injury, we measured the quantity of prostaglandin E2 (PGE2) as the protective factor, and we assessed inhibition of activities related to excessive gastric acid be notorious for aggressive factor and inhibition of Helicobacter pylori (H. pylori) colonization known as a cause of chronic gastritis, gastric ulcer, and gastric cancer. Liriodendrin exhibited higher PGE2 level than rebamipide used as a positive control group at the dose of 500 μM. It was also exhibited acid-neutralizing capacity (10.3%) and H(+)/K(+)-ATPase inhibition of 42.6% (500 μM). In pylorus-ligated rats, liriodendrin showed lower volume of gastric juice (4.38 ± 2.14 ml), slightly higher pH (1.53 ± 0.41), and smaller total acid output (0.47 ± 0.3 mEq/4 hrs) than the control group. Furthermore liriodendrin inhibited colonization of H. pylori effectively. In vivo test, liriodendrin significantly inhibited both of HCl/EtOH-induced gastritis (46.9 %) and indomethacin-induced gastric ulcer (46.1%). From these results, we suggest that liriodendrin could be utilized for the treatment and/or protection of gastritis and gastric ulcer.

    Full Text Available Renal injury is the most common side-effect of aminoglycosides. These antimicrobial drugs are particularly effective against Gram-negative microorganisms. The present study was conducted to investigate the renal protective activity of Cymbopogon citratus in gentamicin-induced nephrotoxicity. Male rabbits were divided into four groups (n=6 including group 1 (0.9% saline treated, group 2 (80 mg/kg/day gentamicin-treated, group 3 (200 mg/kg/day Cymbopogon citratus treated and group 4 (80 mg/kg/day gentamicin and 200 mg/kg/day Cymbopogon citratus treated. Biochemical kidney functioning parameters, urinary enzymes and histopathological examination were performed. The results of the present study showed that simultaneous administration of Cymbopogon citrates and gentamicin significantly protected alteration in body weight, blood urea nitrogen, serum creatinine, creatinine clearance, serum uric acid, serum electrolytes, urinary volume, urinary protein, urinary lactate dehydrogenase and urinary alkaline phosphatase induced by gentamicin. Histological examination of the kidney also suggested the same. It is concluded from the current study that co-administration of Cymbopogon citratus with gentamicin for 3 weeks successfully prevented renal damage associated with aminoglycosides.

    Extracellular histones are mediators of tissue injury and organ dysfunction; therefore they constitute potential therapeutic targets in sepsis, inflammation, and thrombosis. Histone cytotoxicity in vitro decreases in the presence of plasma. Here, we demonstrate that plasma inter-α inhibitor protein (IAIP) neutralizes the cytotoxic effects of histones and decreases histone-induced platelet aggregation. These effects are mediated through the negatively charged glycosaminoglycans (GAGs) chondroitin sulfate and high-molecular-weight hyaluronan (HMW-HA) associated with IAIP. Cell surface anionic glycosaminoglycans heparan sulfate and HA protect the cells against histone-mediated damage in vitro. Surface plasmon resonance showed that both IAIP and HMW-HA directly bind to recombinant histone H4. In vivo neutralization of histones with IAIP and HMW-HA prevented histone-induced thrombocytopenia, bleeding, and lung microvascular thrombosis, decreased neutrophil activation, and averted histone-induced production of inflammatory cytokines and chemokines. IAIP and HMW-HA colocalized with histones in necrotic tissues and areas that displayed neutrophil extracellular traps. Increasing amounts of IAIP-histone complexes detected in the plasma of septic baboons correlated with increase in histones and/or nucleosomes and consumption of plasma IAIP. Our data suggest that IAIP, chondroitin sulfate, and HMW-HA are potential therapeutic agents to protect against histone-induced cytotoxicity, coagulopathy, systemic inflammation, and organ damage during inflammatory conditions such as sepsis and trauma.

    Isorhamnetin has been reported to have anti-inflammatory, anti-oxidative, and anti-proliferative effects. The aim of this study was to investigate the protective effect of isorhamnetin on lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice by inhibiting the expression of cyclooxygenase-2 (COX-2). The effects of isorhamnetin on LPS-induced lung pathological damage, wet/dry ratios and the total protein level in bronchoalveolar lavage fluid (BALF), inflammatory cytokine release, myeloperoxidase (MPO) and superoxide dismutase (SOD) activities, and malondialdehyde (MDA) level were examined. In addition, the COX-2 activation in lung tissues was detected by Western blot. Isorhamnetin pretreatment improved the mice survival rates. Moreover, isorhamnetin pretreatment significantly attenuated edema and the pathological changes in the lung and inhibited protein extravasation in BALF. Isorhamnetin also significantly decreased the levels of inflammatory cytokines in BALF. In addition, isorhamnetin markedly prevented LPS-induced oxidative stress. Furthermore, isorhamnetin pretreatment significantly suppressed LPS-induced activation of COX-2. Isorhamnetin has been demonstrated to protect mice from LPS-induced ALI by inhibiting the expression of COX-2.

  1. Automation of Workplace Lifting Hazard Assessment for Musculoskeletal Injury Prevention

    2014-01-01

    Objectives Existing methods for practically evaluating musculoskeletal exposures such as posture and repetition in workplace settings have limitations. We aimed to automate the estimation of parameters in the revised United States National Institute for Occupational Safety and Health (NIOSH) lifting equation, a standard manual observational tool used to evaluate back injury risk related to lifting in workplace settings, using depth camera (Microsoft Kinect) and skeleton algorithm technology. Methods A large dataset (approximately 22,000 frames, derived from six subjects) of simultaneous lifting and other motions recorded in a laboratory setting using the Kinect (Microsoft Corporation, Redmond, Washington, United States) and a standard optical motion capture system (Qualysis, Qualysis Motion Capture Systems, Qualysis AB, Sweden) was assembled. Error-correction regression models were developed to improve the accuracy of NIOSH lifting equation parameters estimated from the Kinect skeleton. Kinect-Qualysis errors were modelled using gradient boosted regression trees with a Huber loss function. Models were trained on data from all but one subject and tested on the excluded subject. Finally, models were tested on three lifting trials performed by subjects not involved in the generation of the model-building dataset. Results Error-correction appears to produce estimates for NIOSH lifting equation parameters that are more accurate than those derived from the Microsoft Kinect algorithm alone. Our error-correction models substantially decreased the variance of parameter errors. In general, the Kinect underestimated parameters, and modelling reduced this bias, particularly for more biased estimates. Use of the raw Kinect skeleton model tended to result in falsely high safe recommended weight limits of loads, whereas error-corrected models gave more conservative, protective estimates. Conclusions Our results suggest that it may be possible to produce reasonable estimates of

    Full Text Available In most post-industrial countries injury is a leading cause of death, particularly premature death. In Australia, for example, over two thirds of all deaths among persons aged 15 to 24 years are the result of injury. Transport, particularly road transport, is the single most frequent setting for fatal injury. Despite these facts injury research is under-funded and uncoordinated. There is only a fledgling science and little underpinning theory. There is a plethora of unlinked data sets, each reflecting the institutional responsibility of the collecting agency. Even within transport there is little cross modal contact. While the complexities of service delivery demand institutional segregation no such case exits for the segregation of research.

    The role of barrier mucus in mediating the protective effects of 16,16 dimethyl PGE2 (dm PGE2) against ethanol-induced gastric injury, with and without concomitant treatment with N-acetyl-cysteine (NAC), a potent mucolytic agent, was evaluated. Fasted rats were orally administered either saline, 10 micrograms/kg dm PGE2, 20% NAC, or 10 micrograms/kg dm PGE2 plus 20% NAC. In the first study, the rats were killed 15 minutes later and their stomachs were removed and assayed for barrier mucus adherent to the gastric wall using the Alcian blue technique. In the second study, the rats were orally given 2 mL of absolute ethanol (EtOH) after receiving one of these pretreatment regimens, and 5 minutes later they were killed and their stomachs were evaluated histologically by light microscopy for the magnitude of EtOH injury. Although NAC significantly reduced the thickness of barrier mucus by 76% when compared with control animals, it did not adversely affect the ability of dm PGE2 to spare the deep epithelium from injury by EtOH. In fact, NAC was as effective a protective agent as dm PGE2. Neither agent prevented damage to the surface epithelium by EtOH, verifying previous studies regarding the protective effects of prostaglandins. These results indicate that both dm PGE2 and NAC prevent EtOH-induced damage to the deeper layers of the gastric mucosa independent of mucus gel layer thickness, suggesting that other mechanisms than mucus are involved in mediating this protection.

    The number of registered motorcycles in the United States has been steadily increasing, as have the number of motorcycle injuries and fatalities. The Midwest has the lowest incidence of helmet use in the country. Iowa in particular has no helmet law. We conducted a retrospective study of the motorcycle crash victims treated at our level 1 trauma center between 2002 and 2008. Data from 713 motorcycle trauma victims were analyzed for correlations between helmet use and multiple outcome measures. The helmeted cases were similar to the unhelmeted cases in demographic and most crash characteristics. Unhelmeted patients suffered more severe injuries as measured by the Injury Severity Score (P crashes at night (P = .03). Helmeted cases suffered fewer injuries (P injuries, which results in less severe injuries and a more benign hospital course. Helmet use results in significant inpatient cost savings plus additional care and social cost savings by reducing the need for further institutional care. We recommend legal and social measures to induce and encourage helmet use.

    Full Text Available Ozone (O3 is the air pollutant of major concern for vegetation. Levels in Mediterranean cities may exceed the criteria for vegetation protection. Ozone may induce a number of plant responses, e.g., visible injury on the leaves, that affect the ornamental value of urban forests. Antioxidant application may protect sensitive plants from ozone. The most successful synthetic antioxidant is ethylenediurea (EDU. Here we set the optimal EDU dose and concentration (260 mg m-2 leaf, 450 ppm for protecting adult Fraxinus excelsior trees from ozone visible injury by means of EDU applications as soil drench.

    Preconditioning induces ischemic tolerance, which confers robust protection against ischemic damage. We show marked protection with polyinosinic polycytidylic acid (poly-IC) preconditioning in three models of murine ischemia-reperfusion injury. Poly-IC preconditioning induced protection against ischemia modeled in vitro in brain cortical cells and in vivo in models of brain ischemia and renal ischemia. Further, unlike other Toll-like receptor (TLR) ligands, which generally induce significant inflammatory responses, poly-IC elicits only modest systemic inflammation. Results show that poly-IC is a new powerful prophylactic treatment that offers promise as a clinical therapeutic strategy to minimize damage in patient populations at risk of ischemic injury.

  9. Proposed national strategies for the prevention of leading work-related diseases and injuries. Part 1

    1986-01-01

    Preliminary strategies developed at the National Symposium on the Prevention of Leading Work Related Diseases and Injuries, held in Atlanta, Georgia on May 1 to 3, 1985 were revised, elaborated, and further developed. Strategies were developed for the prevention of occupational lung diseases, musculoskeletal injuries, occupational cancers, severe occupational traumatic injuries, and occupational cardiovascular diseases. Lung diseases considered included silicosis, asbestosis, lung cancer mesothelioma, coal workers' pneumoconiosis, byssinosis, occupational asthma, hypersensitivity pneumonitis, asphyxiation, irritation, pulmonary edema, brucellosis, psitticosis, anthrax, mycobacterioses, histoplasmosis, aspergillosis, and coccidioidomycosis. Occupational cancers were discussed as they occur in the lung, pleura, peritoneum, bladder, kidneys, blood, nasal cavity, skin, nasal sinuses, and liver.

    2008-09-01

    Recent prospective evidence supports the hypothesis that impaired trunk control is a contributing factor to sports injuries of the spine as well as to segments of the kinetic chain. The current concepts regarding neuromuscular control of trunk stability are best described from a systems engineering perspective. In the analysis of current neuromuscular training protocols for sports injury prevention, these principles are applied to identify components that optimize neuromuscular control of trunk stability. Current perspectives of neuromuscular learning can be applied clinically to aid in the formulation of injury prevention strategies.

    This study sought to determine if knowledge regarding the risk for knee injuries and the potential for their prevention is being translated to female adolescent soccer players (13-18 years), their parents, and coaches. Eligible participants in the 2007 indoor soccer season were surveyed to determine their knowledge of the risk for and the potential to prevent knee injuries, and their knowledge of effective prevention strategies, if they felt that injury prevention was possible. Team selection was stratified to be representative of both competitive and recreational level play and age group distributions within the selected soccer association. Of the study subjects, 773/1396 (55.4%) responded to the survey: 408 (53%) players, 292 (38%) parents, and 73 (9%) coaches. Most respondents (538 [71%]) were aware of the risk for knee injury. Coaches and parents were more likely than players to view knee injuries as preventable; however, appropriate prevention strategies were often not identified. Four hundred eighty-four (63.8%) respondents reported that they had never received information on knee injuries. Substantial knowledge gaps regarding knee injury prevention and effective preventative strategies were identified. Given the predominance of knee injuries in female adolescent soccer players, there is an urgent need for knowledge translation of prevention strategies to decrease both incidence and long-term consequences of knee injuries. © 2011 John Wiley & Sons A/S.

  12. Maternal PUFA ω-3 Supplementation Prevents Neonatal Lung Injuries Induced by Hyperoxia in Newborn Rats

    Full Text Available Bronchopulmonary dysplasia (BPD is one of the most common complications of prematurity, occurring in 30% of very low birth weight infants. The benefits of dietary intake of polyunsaturated fatty acids ω-3 (PUFA ω-3 during pregnancy or the perinatal period have been reported. The aim of this study was to assess the effects of maternal PUFA ω-3 supplementation on lung injuries in newborn rats exposed to prolonged hyperoxia. Pregnant female Wistar rats (n = 14 were fed a control diet (n = 2, a PUFA ω-6 diet (n = 6, or a PUFA ω-3 diet (n = 6, starting with the 14th gestation day. At Day 1, female and newborn rats (10 per female were exposed to hyperoxia (O2, n = 70 or to the ambient air (Air, n = 70. Six groups of newborns rats were obtained: PUFA ω-6/O2 (n = 30, PUFA ω-6/air (n = 30, PUFA ω-3/O2 (n = 30, PUFA ω-3/air (n = 30, control/O2 (n = 10, and control/air (n = 10. After 10 days, lungs were removed for analysis of alveolarization and pulmonary vascular development. Survival rate was 100%. Hyperoxia reduced alveolarization and increased pulmonary vascular wall thickness in both control (n = 20 and PUFA ω-6 groups (n = 60. Maternal PUFA ω-3 supplementation prevented the decrease in alveolarization caused by hyperoxia (n = 30 compared to PUFA ω-6/O2 (n = 30 or to the control/O2 (n = 10, but did not significantly increase the thickness of the lung vascular wall. Therefore, maternal PUFA ω-3 supplementation may protect newborn rats from lung injuries induced by hyperoxia. In clinical settings, maternal PUFA ω-3 supplementation during pregnancy and during lactation may prevent BPD development after premature birth.

  13. Training on a knife's edge: how to balance triathlon training to prevent overuse injuries.

    Bales, James; Bales, Karrn

    2012-12-01

    The sport of triathlon offers athletes the chance to build and/or maintain cardiovascular fitness across 3 endurance disciplines. Swimming, biking, and running each have a host of overuse injuries that can occur as a result of overtraining. High running mileage, a history of previous injury, inadequate warm up or cool down, and an increase in the years of triathlon experience are a few of the factors that have been linked to triathlon overuse injuries. Early identification of overtraining symptoms and a corresponding reallocation of balance between each discipline, perhaps with an emphasis on increasing swimming, may help prevent many overuse injuries.

    This study aimed to investigate the effects and molecular mechanisms of the effects of apigenin on cisplatin (CP)-induced kidney injury in mice. Apigenin was intraperitoneally administered for 3 consecutive days before CP treatment. We found that apigenin pretreatment significantly attenuated the damage to the kidneys and decreased the levels of serum creatinine, blood urea nitrogen (BUN), glutathione peroxidase (GSH-PX) and superoxide dismutase (SOD), which were increased by CP. Apigenin significantly decreased the levels of TNF-α, IL-1β and TGFβ in the kidneys. Additionally, apigenin inhibited the activations of CYP2E1, phospho-NF-κB p65 and phospho-P38 MAPK in CP-induced renal injury. These results suggest that the renoprotective effects of apigenin may be related to the suppressions of oxidative stress and inflammation in CP-induced renal injury in mice.

    Hamstring strain injuries are the most prevalent muscle injuries in track and field (TF). These injuries often cause prolonged symptoms and a high risk of re-injury. Strengthening of the hamstring muscles has been recommended for injury prevention. The authors review the possible role of eccentric training in TF hamstring injury prevention and introduce exercise classification criteria to guide clinicians in designing strengthening programmes adapted to TF. The principles exposed may serve as a foundation for future development and application of new eccentric programmes to decrease the high incidence of this type of injury in other sports.

    Lower limb overuse injuries are common among people who are exposed to physical stress. Orthotic shoe insoles are widely used to prevent lower limb overuse injuries. Here, we conducted a randomized-controlled study to examine whether the use of orthotic insoles prevents lower limb overuse injuries. Participants (n=228) were randomly assigned to use (n=73) or not to use (n=147) orthotic insoles. The insoles were molded to the shape of the foot to provide support during physical activity. The main outcome measure in the present study was the physician-diagnosed lower limb overuse injury. Thirty-four (46.6%) subjects in the insole group were diagnosed with a lower limb overuse injury compared with 56 (38.1%) in the control group (P=0.29) during the 6-month study period. When body mass index and the results of a 12-min running test and muscle strength were adjusted in a Cox's regression model, the hazard ratio for lower limb overuse injury in the insole group was 1.3 (95% confidence intervals: 0.8-2.1) compared with the control group. Use of orthotic insoles was not associated with a decrease in lower limb overuse injuries. Our findings suggest that routine use of orthotic insoles does not prevent physical-stress-related lower limb injuries in healthy young male adults.

    Horse-related injury can be severe and disabling. We investigated the causes, severity, and costs of equestrian injury with the goal of injury prevention. A retrospective review of horse-related injuries from 2001 to 2008 identified 231 patients with a mean age of 38 years and a mean Injury Severity Score of 11 (range, 1 to 45). Mean length of stay was 5.5 days. Fifty-nine patients (25%) required 84 surgeries. Helmet use was 20 per cent and of the 172 patients not wearing a helmet while mounted, 38 per cent received potentially preventable head injuries. There were three deaths of which two were the result of intracranial hemorrhage in riders not wearing a helmet. Mean hospital charge was $29,800 for a total of $6.9 million. Ninety-one patients completed a survey regarding causation and disability. Thirty-four per cent reported wearing a helmet at the time of injury. Forty per cent reported that poor environmental factors contributed, 30 per cent reported poor horse and rider pairing, and 9 per cent reported equipment failure. Fifty-nine per cent reported long-term disabilities. Compared with the general population, respondents had diminution in their ability to perform usual daily activities associated with physical problems, diminution in social function, and higher bodily pain. We conclude that equestrian injury is costly, disabling, and frequently preventable.

    Full Text Available The thoracic trauma index (TTI and the viscous criterion (VC are injury criteria intended for the prediction of torso injury severity. The criteria were assessed in two series of experiments: 90° (lateral car to car collisions and controlled left trunk impacts against either a rigid or padded wall. Forty-two belt restrained human cadavers in the age range 18–65 years, located in the near-side front passenger seat, were used. The impact velocity was between 40 and 60 km/h. Left and right side impacts were simulated using standard or modified car side structures. With the second series of experiments, the left side of each subject was impacted under one of two different test conditions: 24 km/h rigid wall or 32 km/h padded wall. The thorax deformation was evaluated through the double integration of the accelerated difference at the fourth and eight ribs, near and far side. Deformation maxima of 6–138 mm (mean 69 mm, VC values of 0.3–4.7 m/s (mean 1.6 m/s, and TTI values of 85–252 (mean 63 occurred. Torso abbreviated injury severity (AIS values were between 0 and 5. Statistical analyses showed a stronger influence of age on injury severity than the injury criteria or biomechanical responses in the two series of experiments. The TTI showed the highest correlation with thoracic AIS and the number of rib fractures, while VC was the better predictor of abdominal AIS. The results are discussed critically and the strength and robustness of the injury criteria analyzed.

    Full Text Available The shoulder is at high risk for injury during overhead sports, in particular in throwing or hitting activities, such as baseball, tennis, handball, and volleyball. In order to create a scientific basis for the prevention of recurrent injuries in overhead athletes, four steps need to be undertaken: (1 risk factors for injury and re-injury need to be defined; (2 established risk factors may be used as return-to-play criteria, with cut-off values based on normative databases; (3 these variables need to be measured using reliable, valid assessment tools and procedures; and (4 preventative training programs need to be designed and implemented into the training program of the athlete in order to prevent re-injury. In general, three risk factors have been defined that may form the basis for recommendations for the prevention of recurrent injury and return to play after injury: glenohumeral internal-rotation deficit (GIRD; rotator cuff strength, in particular the strength of the external rotators; and scapular dyskinesis, in particular scapular position and strength.

    Full Text Available Rubber is one of the important commodities in the world. Globally, workers are facing so many problems of hazards that produce by rubber process. In Indonesia, there are several data of occupational problems such as respiratory diseases, muscle and skeletal diseases, gastrointestinal diseases, diseases of the teeth and oral cavity, skin diseases and skin tissue. In Iranian rubber factory, Iran, workers had suffered from some kind of musculoskeletal symptoms. Stomach and liver cancers in workers are having in Shanghai tire factory. In addition, Germany has cancer problem of their workers who work in rubber factory. Most of the rubber process in the factory can cause some hazards of the workers. In unloading area and area that operator is taking the dirt manually, workers are facing ergonomic problems. The possible control is reduce weight of load, team lift the object with two or more workers and Use mechanical assist. Machine safeguarding is essential for protecting from Cutting process that can make workers amputation organs such as hands, and fingers. In bale process, the workers need to cut raw rubber into bale in bale cutting. Furthermore, workers are facing with amputation problem. To manage that, It must be designed as a standard which has interlocking guards to prevent access to the cutting area. When wrapped using plastic, workers use a heated iron and sticked in plastic so that it blends neatly. The risks are fingers can cut accidently and then the workers also get contamination from polyvinyl chloride (PVC. The possible preventions are use an automatic plastic wrapping machine with palletized product sitting on a turntable and respirator. Another problem is contact dermatitis that has been reported frequently among rubber workers. The prevention for that problem is using Gloves. The aim of researcher is to provide the profile of occupational injuries and illnesses, potential hazards in rubber factory to prevent the workers.

    Conventional therapies for diabetic mellitus are not effective in preventing the progression from early diabetic nephropathy (DN) to end-stage renal disease. The role of inflammation in the pathogenesis of DN has been implicated both clinically and experimentally, which provides an alternative therapeutic target for DN. Anti-inflammatory impact of mycophenolate mofetil (MMF) alone and in combination with insulin had been observed in a rat model of experimental DN. In this study, the diabetic rats were subjected to different treatments. Compared to control, the expression levels of CD68, NGF, and NF-kappaB p65, as determined immunohistochemically, were elevated in diabetic rats. Treatment with combined MMF/insulin is associated with a significant reduction in renal tissue of NGF and NF-kappaB p65 expression, macrophage infiltration. It also partially improved the renal function and attenuated renal hypertrophy at early stage of DN. CD68 was found to positively correlate with urinary albumin excretion and NGF. The combined use of MMF/insulin seemed to offer more protections in rats with experimental diabetic renal injury, and the protective effects of MMF might be due to its anti-inflammatory actions through inhibition of NF-kappaB activation and reduction of T cells and macrophage infiltration and/or other kidney chemokine productions.

    Neutrophils recruited to the postischemic kidney contribute to the pathogenesis of ischemia-reperfusion injury (IRI), which is the most common cause of renal failure among hospitalized patients. The Slit family of secreted proteins inhibits chemotaxis of leukocytes by preventing activation of Rho-family GTPases, suggesting that members of this family might modulate the recruitment of neutrophils and the resulting IRI. Here, in static and microfluidic shear assays, Slit2 inhibited multiple steps required for the infiltration of neutrophils into tissue. Specifically, Slit2 blocked the capture and firm adhesion of human neutrophils to inflamed vascular endothelial barriers as well as their subsequent transmigration. To examine whether these observations were relevant to renal IRI, we administered Slit2 to mice before bilateral clamping of the renal pedicles. Assessed at 18 hours after reperfusion, Slit2 significantly inhibited renal tubular necrosis, neutrophil and macrophage infiltration, and rise in plasma creatinine. In vitro, Slit2 did not impair the protective functions of neutrophils, including phagocytosis and superoxide production, and did not inhibit neutrophils from killing the extracellular pathogen Staphylococcus aureus. In vivo, administration of Slit2 did not attenuate neutrophil recruitment or bacterial clearance in mice with ascending Escherichia coli urinary tract infections and did not increase the bacterial load in the livers of mice infected with the intracellular pathogen Listeria monocytogenes. Collectively, these results suggest that Slit2 may hold promise as a strategy to combat renal IRI without compromising the protective innate immune response.

    Pretreatment with ADO prevents the PMA-induced increase in the fluid filtration coefficient (K{sub f}) in isolated perfused rabbit lungs. ADO can block the synthesis of LTs. This study determined whether the protective effect of ADO in PMA induced injury was due to decreased LT production. Isolated rabbit lungs were perfused with a 1:1 mixture of blood and 6% albumin in Krebs-Henseleit buffer. K{sub f} was measured after hemodynamic and weight stabilization and then 30 min after PMA. Perfusate samples were collected after each K{sub f} measurement for determination of LTC{sub 4} and LTD{sub 4} by RIA. The specific role of LT was studied by pretreating with MK-886, a LT synthesis inhibitor. In the vehicle pretreatment group, PMA caused a significant increase in K{sub f} and LTC{sub 4} + LTD{sub 4}. ADO inhibited both the increase in K{sub f} and in LTC{sub 4} + LTD{sub 4}. Pretreatment with MK-886 blocked the PMA-induced increase in LT but did not inhibit the K{sub f} increase. ADO alters the production of LTC{sub 4} + LTD{sub 4} following PMA; but it is probably not the mechanism by which ADO prevents the increase in microvascular permeability.

    The organization of sports at the national level has seldom been included in scientific discussions of sports injury prevention. The aim of this study was to develop a model for organization of sports that supports prevention of overuse injuries. The quality function deployment technique was applied in seminars over a two-season period to develop a national organizational structure for athletics in Sweden that facilitates prevention of overuse injuries. Three central features of the resulting model for organization of sports at the national level are (a) diminishment of the organizational hierarchy: participatory safety policy design is introduced through annual meetings where actors from different sectors of the sporting community discuss training, injury prevention, and sports safety policy; (b) introduction of a safety surveillance system: a ubiquitous system for routine collection of injury and illness data; and (c) an open forum for discussion of safety issues: maintenance of a safety forum for participants from different sectors of the sport. A nonhierarchical model for organization of sports at the national level - facilitated by modern information technology - adapted for the prevention of overuse injuries has been developed. Further research is warranted to evaluate the new organizational model in prospective effectiveness studies.

    To describe the physiotherapists perceptions and the current practices for injury prevention in elite football (soccer) clubs in Brazil. Cross-sectional study. Group of Science in Sports & Exercise, Federal University of Healthy Sciences of Porto Alegre (Brazil). 16 of the 20 football clubs involved in the Brazilian premier league 2015. Physiotherapists answered a structured questionnaire. Most physiotherapists (∼88%) were active in design, testing and application of prevention programs. Previous injury, muscle imbalance, fatigue, hydration, fitness, diet, sleep/rest and age were considered "very important" or "important" injury risk factors by all respondents. The methods most commonly used to detect athletes' injury risk were: monitoring of biochemical markers (100% of teams), isokinetic dynamometry (81%), questionnaires (75%), functional movement screen (56%), fleximetry (56%) and horizontal jump tests (50%). All clubs used strength training, functional training, core exercises and balance/proprioception exercises in their injury prevention program; and Nordic hamstring exercise and other eccentric exercises were used by 94% of clubs. "FIFA 11+" prevention program was adapted by 88% of clubs. Physiotherapists perceptions and current practices of injury prevention within Brazilian elite football clubs were similar to those employed in developed countries. There remains a gap between clinical practice and scientific evidence in high performance football. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Cyanide is a life-threatening, bioterrorist agent, preventing cellular respiration by inhibiting cytochrome c oxidase, resulting in cardiopulmonary failure, hypoxic brain injury, and death within minutes. However, even after treatment with various antidotes to protect cytochrome oxidase, cyanide intoxication in humans can induce a delayed-onset neurological syndrome that includes symptoms of Parkinsonism. Additional mechanisms are thought to underlie cyanide-induced neuronal damage, including generation of reactive oxygen species. This may account for the fact that antioxidants prevent some aspects of cyanide-induced neuronal damage. Here, as a potential preemptive countermeasure against a bioterrorist attack with cyanide, we tested the CNS protective effect of carnosic acid (CA), a pro-electrophilic compound found in the herb rosemary. CA crosses the blood-brain barrier to up-regulate endogenous antioxidant enzymes via activation of the Nrf2 transcriptional pathway. We demonstrate that CA exerts neuroprotective effects on cyanide-induced brain damage in cultured rodent and human-induced pluripotent stem cell-derived neurons in vitro, and in vivo in various brain areas of a non-Swiss albino mouse model of cyanide poisoning that simulates damage observed in the human brain. Cyanide, a potential bioterrorist agent, can produce a chronic delayed-onset neurological syndrome that includes symptoms of Parkinsonism. Here, cyanide poisoning treated with the proelectrophillic compound carnosic acid, results in reduced neuronal cell death in both in vitro and in vivo models through activation of the Nrf2/ARE transcriptional pathway. Carnosic acid is therefore a potential treatment for the toxic central nervous system (CNS) effects of cyanide poisoning.

    Physical education (PE) teachers are at a high risk of musculoskeletal sports or work-related injuries because of the physical activity as inherent part of their profession. Such injuries have a negative impact on work and leisure time activities, and effective injury prevention interventions are needed. The present study aimed at testing the effectiveness of an injury prevention intervention that was developed and optimized according to PE teachers' wishes and values. Fifty-five PE teachers were randomly assigned to intervention or control group. Intervention group teachers engaged in two days of training during which they familiarized with eight injury prevention strategies (seven intrinsic and one extrinsic). A special feature of the intervention was that the way of delivery was based on the self-determination theory in order to stimulate participants' motivation to adhere to the proposed strategies. Prospective registrations during one school year were conducted concerning injuries and preventive behaviours. Results showed that the intervention group teachers had a lower number of injuries per 1000 h time of exposure (TOE) than the controls (INT: 0.49, CON: 1.14 injuries/1000 h TOE, OR: 2.32, 95% CI: 1.06-5.07), and applied a broader variety of strategies including dynamic and static stretching, core stability, balance and strength training, when compared to the controls who mainly engaged in warming-up. In conclusion, with the same amount of time, an injury reduction was found in PE teachers through a more balanced use of provided preventive strategies.

    Injuries affect the lives of thousands of young people and their families each year in India. With the gradual decline of communicable and nutritional diseases, injuries will be a leading cause of mortality, morbidity and disabilities and the success achieved so far in child health and survival is in jeopardy. Available data indicate that among children less than 18 y, 10-15 % of deaths, 20-30 % of hospital registrations and 20 % of disabilities are due to injuries. Based on available data, it is estimated that injuries result in death of nearly 1, 00,000 children every year in India and hospitalisations among 2 million children. Road Traffic Injuries (RTI's), drowning, falls, burns and poisoning are leading injury causes in India. Drowning and burns are major causes of mortality in less than 5 y, while RTIs, falls and poisoning are leading causes in 5-18 y. A shift in the occurrence of suicides to younger age groups of 15-20 y is a matter of serious concern in recent years. More number of males, those in rural areas, and majority of poor income households are affected due to injuries.Child injuries are predictable and preventable. Children have limitations of size, development, vision, hearing and risk perceptions as compared to adults and hence are more susceptible and vulnerable to injuries. Thus, it is important to make products and home - road and school environments safer along with greater supervision by parents and care givers. The key approaches include vehicle and product safety, environmental modification, legislation and enforcement, education and skills development along with availability of quality trauma care. Child injury prevention and care requires good quality data, building human and financial resources, strengthening policies and programmes based on evidence and integrated implementation of countermeasures along with monitoring and evaluation. Child injury prevention and control is crucial and should be an integral part of child health and

    AIM: To determine the potential protective role of adiponectin in intestinal ischemia reperfusion (I/R) injury. METHODS: A rat model of intestinal I/R injury was established. The serum level of adiponectin in rats with intestinal I/R injury was determined by enzyme-linked immunosorbent assay (ELISA). The serum levels of interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α were also measured by ELISA. Apoptosis of intestinal cells was detected using the terminal deoxynucleotidyl transferase dUTP nick end labeling assay. The production of malondialdehyde (MDA) and superoxide dismutase (SOD) and villous injury scores were also measured. RESULTS: Adiponectin was downregulated in the serum of rats with intestinal I/R injury compared with sham rats. No significant changes in the expression of adiponectin receptor 1 and adiponectin receptor 2 were found between sham and I/R rats. Pre-treatment with recombinant adiponectin attenuated intestinal I/R injury. The production of pro-inflammatory cytokines, including IL-6, IL-1β, and TNF-α, in rats with intestinal I/R injury was reduced by adiponectin pre-treatment. The production of MDA was inhibited, and the release of SOD was restored by adiponectin pre-treatment in rats with intestinal I/R injury. Adiponectin pre-treatment also inhibited cell apoptosis in these rats. Treatment with the AMP-activated protein kinase (AMPK) signaling pathway inhibitor, compound C, or the heme oxygenase 1 (HO-1) inhibitor, Snpp, attenuated the protective effects of adiponectin against intestinal I/R injury. CONCLUSION: Adiponectin exhibits protective effects against intestinal I/R injury, which may involve the AMPK/HO-1 pathway. PMID:26715807

    Full Text Available Abstract Background Injuries are a major cause of mortality and morbidity which together result in avoidable societal costs. Due to limited resources, injury prevention interventions need to demonstrate cost-effectiveness to justify their implementation. However, the existing knowledge in this area is limited. Consequently, a systematic review is needed to support decision-making and to assist in the targeting of future research. The aim of this review is to critically appraise the published economic evidence of injury prevention interventions at the municipal level. Methods A search strategy was developed to focus a literature search in PubMed, Embase, Cochrane and NHS EED. Studies were eligible for inclusion if they were economic evaluations of injury prevention interventions that could be implemented by municipalities; had a relevant comparison group; did not include any form of medication or drug use; and were assessed as having at least an acceptable quality from an economic point of view. Articles were screened in three steps. In the final step, studies were critically appraised using a check-list based on Drummond's check-list for assessing economic evaluations. Results Of 791 potential articles 20 were accepted for inclusion. Seven studies showed net savings; four showed a cost per health score gained; six showed both savings and a cost per health score gained but for different time horizons and populations; and three showed no effect. The interventions targeted a range of areas such as traffic safety, fire safety, hip fractures, and sport injuries. One studied a multi-targeted community-based program. Only six articles used effectiveness data generated within the study. Conclusions The results indicate that there are injury prevention interventions that offer good use of societal resources. However, there is a lack of economic evidence surrounding injury prevention interventions. This lack of evidence needs to be met by further research

    BACKGROUND: In patients with cerebrovascular disease, by means of the neuroendocrine system, acupuncture supports the transformation of a local pathological status into a physiological status. Recently, great progress has been made in studying the protective effects of acupuncture on brain ischemia/reperfusion injury. OBJECTIVE: To summarize research advances in the protective effects of acupuncture on brain ischemia/reperfusion injury. RETRIEVAL STRATEGY: Using the terms "acupuncture, transcutaneous electrical acupoint stimulation, cerebral ischemia/reperfusion injury, and cerebral protection", we retrieved articles from the PubMed database published between January 1991 and June 1994. Meanwhile, we searched the China National Knowledge Infrastructure with the same terms. Altogether, 114 articles and their results were analyzed. Inclusive criteria: studies that were closely related to the protective effects of acupuncture on brain ischemia/reperfusion injury, or studies, whose contents were in the same study field and were published recently, or in the authorized journals. Exclusive criteria: repetitive studies. LITERATURE EVALUATION: Thirty articles that related to the protective effects of acupuncture on brain ischemia/reperfusion injury were included. Among them, 7 were clinical studies, and the remaining 23 articles were animal experimental studies. DATA SYNTHESIS: ① Animal experimental studies have demonstrated that acupuncture improves brain blood perfusion and brain electrical activity, influences pathomorphological and ultramicrostructural changes in ischemic brain tissue, is beneficial in maintaining the stability of intracellular and extracellular ions, resists free radical injury and lipid peroxidation, and influences cytokine, neurotransmitter, brain cell signal transduction, and apoptosis-regulating genes. ② Clinical studies have demonstrated that acupuncture not only promotes nutritional supply to local brain tissue in patients with cerebral

  18. Injuries in epilepsy: a review of its prevalence, risk factors, type of injuries and prevention

    Full Text Available Currently, there is intense clinical research into various aspects of the medical risks relating to epilepsy, including total and cause-specific mortality, accidents and injuries in patients with epilepsy and mortality related with seizures. Seizures occurring in precarious situations and resulting in injuries are still an important concern for patients with epilepsy, their employers and their caregivers. Submersion injuries, motor vehicle accidents, burns, and head injuries are among the most feared epilepsy-related injuries. These concerns seem valid because the hallmark of epilepsy, episodic impairment of consciousness and motor control, may occur during interictal EEG epileptiform discharges, even in the absence of a clinical seizure. In addition, psychomotor comorbidity and side effects of antiepileptic drugs may contribute to the risk of injuries in patients with epilepsy. Published risk factors for injuries include the number of antiepileptic drugs, history of generalized seizures, and seizure frequency. In general, epidemiological information about incidence of injuries has been conflicting and sparse. In general, studies focusing on populations with more severe forms of epilepsy tend to report substantially higher risks of injuries than those involving less selected populations. On the other hand, studies based on non-selected populations of people with epilepsy have not shown an increased frequency of injuries in people with epilepsy compared with the general population. Some studies have shown that patients with epilepsy are more frequently admitted to the hospital following an injury. Possible explanations include: more cautious attitude of clinicians toward injuries occurring in the setting of seizures; hospitalization required because of seizures and not to the injuries themselves; and hospitalization driven by other issues, such as comorbidities, which are highly prevalent in patients with epilepsy. Potentially the high rate of
