PURPOSE: All-terrain vehicles (ATV's) are a hazardous source of injury in many contexts and geographical regions, but to date have not been investigated in Saskatchewan. METHODS: Baseline surveys from the Saskatchewan Farm Injury Project were examined at two time points in terms of: 1) rates and correlated characteristics of reported ATV use; and 2) qualitative content analysis of injury events involving ATVs. The sample of eligible farmers was 2972 in 2007 and 1702 in 2013...

BACKGROUND: Previous work shows that young athletes after anterior cruciate ligament reconstruction (ACLR) demonstrate single-leg (SL) landing movement asymmetries at the time of return to sport (RTS); however, the effect of movement asymmetries on longitudinal knee-related function after ACLR has not been examined. Hypothesis/Purpose: The purpose of this study was to examine the effect of SL drop-landing movement symmetry at the time of RTS on knee-related function 2 years later in young athletes after ACLR...

Aggregation of cytosolic proteins is a pathological finding in disease states, including ageing and neurodegenerative diseases. We have previously reported that hypoxia induces protein misfolding in Caenorhabditis elegans mitochondria, and electron micrographs suggested protein aggregates. Here, we seek to determine whether mitochondrial proteins actually aggregate after hypoxia and other cellular stresses. To enrich for mitochondrial proteins that might aggregate, we performed a proteomics analysis on purified C...

Monitoring brain integrity and neuro-cognitive function is a new and important target for the management of a patient treated with extracorporeal membrane oxygenation (ECMO), in particular because of the increasing awareness of cerebral abnormalities that may potentially occur in this setting. Continuous regular monitoring, as well as repeated assessment for cerebral complications has become an essential element of the ECMO patient management. Besides well-known complications, like bleeding, ischemic stroke, seizures, and brain hypoperfusion, other less defined yet relevant injury and clinical manifestations are increasingly reported and impacting on ECMO patient prognosis at short term...

Little is known about how psychosocial work factors such as work stress, supervisor fairness, and language barriers affect risk of occupational injury among Latino farmworkers. This study attempts to address these questions. Surveys were administered via interviews to 225 Latino thoroughbred farmworkers. Multivariable logistic regression analyses were performed to calculate odds ratios (OR) and 95% confidence intervals (CI) of occupational injury in the past year in relation to occupational characteristics...

Injunctive safety norms (ISNs) refer to perceptions of others' expectations of one's safety-related conduct. Drawing on a sample of Canadian young workers (n=11,986;M age=17.90years; 55% males), we study the relationships among four sources of non-work-related (i.e., parents, siblings, friends, teachers), two sources of work-related (i.e., supervisors, co-workers) ISNs, young workers' self-reported work-related risk-taking behaviors, and workplace injuries. Structural equation modeling suggests that ISNs from parents, supervisors, and co-workers were related to less frequent work-related risk-taking behaviors, and with fewer workplace injuries via less frequent work-related risk-taking behaviors...

Ischemic stroke is a devastating neurological disorder and one of the leading causes of death and serious disability in adults. Adult neural stem cell (NSC) replacement therapy is a promising treatment for both structural and functional neurological recovery. However, for the treatment to work, adult NSCs must be protected against hypoxic-ischemic damage in the ischemic penumbra. In the present study, we aimed to investigate the neuroprotective effects of the mfat-1 transgene on cobalt chloride (CoCl2 )-induced hypoxic-ischemic injury in cultured adult NSCs as well as its underlying mechanisms...

Our previous work showed that purple sweet potato color (PSPC), a class of naturally occurring anthocyanins, effectively improved hepatic glucose metabolic dysfunction in high-fat diet (HFD)-treated mice. This study investigated the effects of PSPC on HFD-induced hepatic steatosis and the signalling events associated with these effects. Mice were divided into four groups: Control group, HFD group, HFD+PSPC group and PSPC group. PSPC was administered daily for 20 weeks at oral doses of 700 mg/kg/day. Our results showed that PSPC significantly improved obesity and related metabolic parameters, as well as liver injury in HFD-treated mice...

Mitochondrial dysfunction is known as one of causative factors in ischemic stroke, leading to neuronal cell death. The present work was undertaken to investigate whether succinate induces neuron apoptosis by regulating mitochondrial morphology and function. In neurons, oxygen-glucose deprivation induced succinate accumulation due to the reversal of succinate dehydrogenase (SDH) activation, leading to mitochondrial fission. Kaempferol inhibited mitochondrial fission and maintained mitochondrial HK-II through activation of Akt, and thereby protected neurons from succinate-mediated ischemi injury...

BACKGROUND: Cognitive impairment in people with traumatic brain injury (TBI) could affect multiple facets of their daily functioning. Cognitive rehabilitation brings about clinically significant improvement in certain cognitive skills. However, it is uncertain if these improved cognitive skills lead to betterments in other key aspects of daily living. We evaluated whether cognitive rehabilitation for people with TBI improves return to work, independence in daily activities, community integration and quality of life...

BACKGROUND: The use of laparoscopy in managing haemodynamically stable patients with penetrating thoracoabdominal injuries in developed countries is wildly practiced, but in Africa, the use of laparoscopy is still in its infancy stage. We reviewed a single centre experience in using laparoscopy in Africa for management of patients with both isolated diaphragmatic injuries as well as diaphragmatic injuries associated with intra-abdominal injuries requiring intervention. METHODS: A retrospective analysis of prospectively collected data of patients presenting with penetrating thoracoabdominal injuries was done...

REVIEW
Jing Qu, Huanxiang Zhang
Spinal cord injury (SCI) represents one of the most complicated and heterogeneous pathological processes of central nervous system (CNS) impairments, which is still beyond functional regeneration. Transplantation of mesenchymal stem cells (MSCs) has been shown to promote the repair of the injured spinal cord tissues in animal models, and therefore, there is much interest in the clinical use of these cells. However, many questions which are essential to improve the therapy effects remain unanswered. For instance, the functional roles and related molecular regulatory mechanisms of MSCs in vivo are not yet completely determined...

BACKGROUND: The benefits of work for physical, psychological, and financial wellbeing are well documented. Return to work (RTW) after unintentional injury is often delayed, and psychological morbidity may contribute to this delay. The impact of psychological morbidity on RTW after a wide range of unintentional injuries in the UK has not been adequately quantified. AIM: To quantify the role of psychological factors, including anxiety, depression, and post-traumatic distress, on RTW following unintentional injuries...

BACKGROUND: Suicide rates among those employed in male-dominated professions such as construction are elevated compared to other occupational groups. Thus far, past research has been mainly quantitative and has been unable to identify the complex range of risk and protective factors that surround these suicides. METHODS: We used a national coronial database to qualitatively study work and non-work related influences on male suicide occurring in construction workers in Australia...

There are numerous challenges associated with the acute care of traumatic limb injuries in forward military settings. A lack of immediate medical facilities necessitates that the wound dressing perform multiple tasks including exudate control, infection prevention, and physical protection of the wound for extended periods of time. Here, kaolin was incorporated into recently developed robust polyurethane (PU) hydrogel foams at 1-10wt% in an effort to impart hemostatic character. ATR-IR and gel fraction analysis demonstrated that the facile, one-pot synthesis of the PU hydrogel was unaffected by kaolin loading, as well as the use of a non-toxic catalyst, which significantly improved cytocompatibility of the materials...

BACKGROUND: Currently, there is an extensive but highly inconsistent body of literature regarding donor adverse events (AEs) in haemapheresis. As the reports diverge with respect to types and grading of AEs, apheresis procedures and machines, the range of haemapheresis-related AEs varies widely from about 0.03% to 6.6%. METHODS: The German Society for Transfusion Medicine and Immunohaematology (DGTI) formed a 'Haemapheresis Vigilance Working Party' (Arbeitsgemeinschaft Hämapheresevigilanz; AGHV) to create an on-line registry for comprehensive and comparable AE assessment with all available apheresis devices in all types of preparative haemapheresis: plasmapheresis (PLS), plateletpheresis (PLT), red blood cell apheresis, all kind of leukaphereses (autologous/allogeneic blood stem cell apheresis, granulocyte apheresis, lymphocyte/monocyte apheresis) and all possible types of multi-component apheresis...

Latino day laborers (LDLs) are at elevated risks for disease and injury because of the environments in which they work. Despite this recognition, a comprehensive examination of factors related to LDLs' health service use remains unexamined. Using the Andersen model, the current exploratory study examined predisposing (age, education level, location of educational training, legal status, and marital status), enabling (income, trust in medical personnel, whether the respondent has someone they consider their personal doctor, and whether their doctor speaks the same language, perceived barriers to care), and need (self-rated health, number of chronic conditions) variables to predict use of health services among a purposive sample of LDLs ( N = 150)...

Repetitive transcranial magnetic stimulation (rTMS), a non-invasive form of brain stimulation, has shown experimental and clinical efficacy in a range of neuromodulatory models, even when delivered at low intensity (i.e. subthreshold for action potential generation). After central nervous system (CNS) injury, studies suggest that reactive astrocytes and microglia can have detrimental but also beneficial effects; thus modulating glial activity, for example through application of rTMS, could potentially be a useful therapeutic tool following neurotrauma...
