BACKGROUND: Despite improvements in the management of severely injured patients, development of multiple organ dysfunction syndrome (MODS) remains a morbid complication of traumatic shock. One of the key attributes of MODS is a profound bioenergetics crisis, for which the mediators and mechanisms are poorly understood. We hypothesized that metabolic uncoupling using an experimental PI3-kinase inhibitor, LY294002 (LY), may prevent mitochondrial abnormalities that lead to the generation of mitochondrial DNA (mtDNA) damage and the release of mtDNA damage associated molecular patterns (DAMPs) METHODS: 16 swine were studied using LY294002 (LY), a non-selective PI3-KI: Animals were assigned to Trauma only (TO, N=3); LY drug only (LYO, N=3); and Experimental (N=10), trauma + drug (LY+T) groups...

STUDY DESIGN: Retrospective chart review. OBJECTIVE: The study purpose was to examine the feasibility of acute (<24 hours) and hyper-acute (<8 hours) treatment of thoracolumbar burst fractures to maintain or improve spinal injury scores. SUMMARY OF BACKGROUND DATA: Historically, treatment of spinal burst fractures within 24 hours from injury was considered an "acute" treatment timeframe. Patient polytrauma triage, multiple surgical specialty and hospital resource coordination affect time to treatment...

AIM: Acute kidney injury (AKI) is common following deliberate self-poisoning with a combination washing powder containing oxalic acid (H2C2O4) and potassium permanganate (KMnO4). Early and rapid increases in serum creatinine (sCr) follow severe poisoning. We investigated the relationship of these increases with direct nephrotoxicity in an ongoing multicenter prospective cohort study in Sri Lanka exploring AKI following poisoning. METHODS: Multiple measures of change in kidney function were evaluated in 48 consenting patients who had serial sCr and serum cystatin C (sCysC) data available...

It is becoming increasingly clear that neuroinflammation has a causal role in the pathogenesis of central nervous system (CNS)-related diseases, and therefore therapeutic strategies targeting the regulation or availability of inflammatory mediators can be used to prevent or mitigate pathology. Interestingly, the proinflammatory cytokine, interleukin-1 beta (IL-1β), has been implicated in perpetuating immune responses and contributing to disease severity in a variety of CNS diseases ranging from multiple sclerosis, neurodegenerative diseases, traumatic brain injury, and diabetic retinopathy...

Ingestion of caustic substances and its long-term effect on the gastrointestinal system maintain its place as an important public health issue in spite of the multiple efforts to educate the public and contain its growing number. This is due to the ready availability of caustic agents and the loose regulatory control on its production. Substances with extremes of pH are very corrosive and can create severe injury in the upper gastrointestinal tract. The severity of injury depends on several aspects: Concentration of the substance, amount ingested, length of time of tissue contact, and pH of the agent...

INTRODUCTION: Alpha-1-adrenergic receptors (α1-ARs) are G-protein coupled receptors (GPCRs) with three highly homologous subtypes (α1A, α1B, and α1D). Of these three subtypes, only the α1A and α1B are expressed in the heart. Multiple pre-clinical models of heart injury demonstrate cardioprotective roles for the α1A. Non-selective α1-AR activation promotes glycolysis in the heart, but the functional α1-AR subtype and broader metabolic effects have not been studied. OBJECTIVES: Given the high metabolic demands of the heart and previous evidence indicating benefit from α1A activation, we chose to investigate the effects of α1A activation on the cardiac metabolome in vivo...

Radiation damage can occur in nuclear power plant workers when physical protections fail, which results in nuclear leakage through the protective layers. Alternatively, workers may be unable to use physical protection in time (in the case of a sudden nuclear weapons attack). In addition, patients who receive local radiotherapy and are not allowed to adopt local physical protection may experience radiation damage. Thus, protection against chemical radiation has become indispensable. In view of the side effects caused by synthetic radioprotective agents (such as amisfostine), searching for radioprotective agents from plant sources is an alternative strategy...

James Brady, the White House press secretary during President Ronald Reagan's first term in office, was 1 of 4 people (including the President) wounded during an attempted assassination attempt on President Reagan's life on March 30, 1981. John Hinckley, Jr. was found not guilty of this attempt by reason of insanity. The assassination attempt was a ploy by Hinckley, Jr. to impress the actress Jodie Foster. Brady was the most seriously injured of the 4 who were wounded. He suffered a gunshot wound to the left forehead that traveled through the left frontal lobe, corpus callosum, and then into the right frontal and temporal lobes...

Objective: fall-related injuries constitute major health risks in older individuals, and these risks are projected to increase in parallel with increasing human longevity. Impaired postural stability is a potential risk factor related to falls, although the evidence is inconclusive, partly due to the lack of prospective studies. This study aimed to investigate how objective measures of postural sway predict incident falls. Design, setting and participants: this prospectively observational study included 1,877 community-dwelling individuals aged 70 years who participated in the Healthy Ageing Initiative between June 2012 and December 2015...

BACKGROUND: During a war, many civilians are severely injured by firearms, bombs, and shrapnel. The triage of war injuries involves difficult and complicated processes requiring surgical procedures and patient monitoring in the Intensive Care Unit (ICU) of hospitals. In this study, we examine the demographic, traumatic, and critical care characteristics of cases injured during the civil war in Syria and requiring emergency surgery. METHODS: Electronic data of the traumatic, surgical, and ICU monitoring features of 707 patients admitted to Kilis Public Hospital between March 2012 and January 2013 were analyzed retrospectively RESULTS: Most of the patients reported having been injured due to firearms (83...

High elbow torque during a pitch may contribute to injury risk. Our objective was to determine the pitch mechanics associated with elbow varus torque in youth baseball pitchers. Eighteen male youth pitchers (age=15.5±1.6 years) threw three fastballs and three change-ups from a windup position while undergoing three-dimensional kinematic analysis. Independent variables included ball release point distance, stride length, lateral pelvic tilt, and ball velocity. Two multiple regression models, separated by pitch type (fastball, change-up) were used to determine the association of independent variables with peak varus torque at the elbow...

In the general population, females experience depression at significantly higher rates than males. Individuals with traumatic brain injury (TBI) are at substantially greater risk for depression compared to the overall population. Treatment of, and recovery from, TBI can be hindered by depression; comorbid TBI and depression can lead to adverse outcomes and negatively affect multiple aspects of individuals' lives. Gender differences in depression following TBI are not well understood, and relevant empirical findings have been mixed...

OBJECTIVE: Prior research with youth exposed to violence suggests that, in this high-risk population, boys may be victims of sexual teen dating violence (TDV) and injury as frequently as girls. We sought to replicate these findings with a demographically similar sample and to determine whether the findings could be attributed the high-risk nature of the sample by assessing the impact of violence exposure on sex differences. METHODS: A cross-sectional sample of 2577 youth (ages 11-18, M=15...

Current treatment options for spinal cord injury (SCI) are scarce. One of the most promising innovative approaches include gene-therapy, however no single gene has so far been shown to be of clinical relevance. This study investigates the efficacy of various combinations of vascular endothelial growth factor (VEGF), glial cell-derived neurotrophic factor (GDNF), angiogenin (ANG) and neuronal cell adhesion molecule (NCAM) in rats. Multiple therapeutic genes were administered intrathecally either via adenoviral vectors or by using genetically modified human umbilical cord blood mononuclear cells (hUCBMCs)...

The purpose of this review is to describe recent clinical and epidemiological studies examining the adverse effects of urban air pollution on the central nervous system (CNS). Air pollution and particulate matter (PM) are associated with neuroinflammation and reactive oxygen species (ROS). These processes affect multiple CNS pathways. The conceptual framework of this review focuses on adverse effects of air pollution with respect to neurocognition, white matter disease, stroke, and carotid artery disease. Both children and older individuals exposed to air pollution exhibit signs of cognitive dysfunction...

BACKGROUND: Hidradenocarcinoma is a rare malignant tumour involving the sweat glands. It classically arises de novo, only rarely resulting from pre-existing hidradenoma. The literature contains few reports of lymph node metastasis in this tumour. We report a case of a patient with hidradenocarcinoma of the heel associated with inguinal node metastases. PATIENTS AND METHODS: We report the case of a 64-year-old patient with a history of chronic smoking, who in the last two years developed a painless nodule in his right heel, with no prior injury, and which gradually increased in size to become an ulcerated tumour...

Dihydroartemisinin is an effective antimalarial agent with multiple biological activities. In the present investigation, we elucidated its therapeutic potential and working mechanism on human tongue squamous cell carcinoma (TSCC). It was demonstrated that dihydroartemisinin could significantly inhibit cell growth in a dose- and time-dependent manner by the Cell Counting Kit-8 and colony formation assay in vitro. Meanwhile, autophagy was promoted in the Cal-27 cells treated by dihydroartemisinin, evidenced by increased LC3B-II level, increased autophagosome formation, and increased Beclin-1 level compared to dihydroartemisinin-untreated cells...
