Epidemiology muscle injuries

Fei Chen, Yong Peng, Mao Chen
Cardiac involvement in idiopathic inflammatory myopathies (IIMs) attracts more attention than it ever did because of its morbidity and impact on worse prognosis, although the accurate information needs further epidemiological studies. Early identification and intervention for the diseased heart may help improve the clinical outcomes of IIMs with cardiac involvement. Cardiac troponin assays, allowing for sensitive detection of minor myocardium injury, may provide a new way for early detection for heart involvement in IIMs...

BACKGROUND: Severe acute muscle injury results in massive cell damage, causing the release of actin into extracellular fluids where it complexes with the vitamin D binding protein (DBP). We hypothesized that a systemic Vitamin D deficiency would result in a less pro-inflammatory phenotype. METHODS: C57BL/6 wild-type and DBP deficient (DBP-/-) mice received intramuscular injections of either 50% glycerol or phosphate-buffered saline into thigh muscles. Muscle injury was assessed by histology...

Tetanus is an acute specific infection caused by obligate anaerobes, which is still a serious public health problem. Tetanus bacterium is an obligate anaerobic bacterium, widely distributed in nature, which can exist in dust, soil, human or animal excrement. The bacteria invade the body primarily through the skin or mucosal wounds, and most commonly in trauma and burn patients, unclean newborns, and unsafe surgical instruments. Exotoxin produced by tetanus bacteria can cause temporary changes in the central nervous system, manifested as systemic skeletal muscle persistence and paroxysmal spasm, severe cases of laryngospasm, asphyxia, lung infections and organ failure, which is a very serious and potentially fatal disease...

BACKGROUND: A range of devastating blast injuries have been sustained by personnel during recent conflicts. Previous studies have focused on severe injuries, including to the spine, however, no study has specifically focused on the most common spinal injury; transverse process (TP) fractures. Although their treatment usually requires limited intervention, analysis of TP fractures may help determine injury mechanisms. METHODS: Data was collected from victims with spinal fractures injured in Improvised Explosive Device (IED) attacks, from the UK's Joint Theatre Trauma Registry...

Introduction-We have previously published on the ventricular fibrillation (VF) risk with TASER® X26 conducted electrical weapon (CEW). Our risk model accounted for realistic body mass index distributions, modeled the effects of partial or oblique dart penetration, and used epidemiological CEW statistics. As new CEWs have become available to law enforcement, their cardiac safety profile was not quantified. Therefore, we applied our VF probability model to evaluate their cardiac risk. Methods and Results-An eXperimental Rotating-Field (XRF) waveform CEW and the X2 CEW are new 2-shot electrical weapon models designed to target a precise amount of delivered charge per pulse, 64 μC and 62 μC, respectively...

Chronic alcohol consumption is a well-known risk factor for tissue injury. The link between alcohol use disorder (AUD) and kidney injury is intriguing but controversial, and the molecular mechanisms by which alcohol may damage the kidneys are poorly understood. Epidemiological studies attempting to link AUD and kidney disease are, to date, inconclusive, and there is little experimental evidence directly linking alcohol consumption to kidney injury. However, studies conducted primarily in other organs and tissues suggest several possible mechanisms by which alcohol may promote kidney dysfunction...

CONTEXT: Thigh muscles strains are among the most common injuries in high school soccer for both males and females. Similar results have been reported among collegiate soccer players, specifically for hamstring strains. In collegiate soccer, males have a higher injury rate than women although they share common injury characteristics. Currently, no studies exist comparing the injury rate or injury characteristics of thigh muscle strains between sexes playing high school soccer. OBJECTIVE: To compare thigh muscle strain injury rates and injury event characteristics among sexes participating in high school soccer...

INTRODUCTION: The severity of exertional heat illnesses (EHI) ranges from relatively minor heat exhaustion to potentially life-threatening heat stroke. Epidemiological surveillance of the types of and trends in EHI incidence depends on application of the appropriate International Classification of Disease, 9th Revision (ICD-9) diagnostic code. However, data examining whether the appropriate EHI ICD-9 code is selected are lacking. The purpose of this study was to determine whether the appropriate ICD-9 code is selected in a cohort of EHI casualties...

BACKGROUND: Dickkopf-related protein 3 (DKK3) is a secreted protein that is involved in the regulation of cardiac remodeling and vascular smooth muscle cell differentiation, but little is known about its role in atherosclerosis. METHODS: We tested the hypothesis that DKK3 is atheroprotective using both epidemiological and experimental approaches. Blood DKK3 levels were measured in the Bruneck Study in 2000 (n=684) and then in 2005 (n=574). DKK3-deficient mice were crossed with apolipoprotein E(-/-) mice to evaluate atherosclerosis development and vessel injury-induced neointimal formation...

Epidemiological studies have indicated that smoking is a pivotal risk factor for the progression of several chronic diseases. Nicotine, the addictive component of cigarettes, has powerful pathophysiological properties in the body. Although the effects of cigarette smoking on corneal re-epithelialization have been studied, the effects of nicotine on corneal wound healing-related neovascularization and fibrosis have not been fully demonstrated. The aim of this study was to evaluate the effects of chronic administration of nicotine on corneal wound healing following acute insult induced by an alkali burn...
