Accuracy of physical activity estimates predicted by activity monitoring technologies may be affected by device location, analysis algorithms, type of technology (i.e. wearable/stickable) and population demographics (disability) being studied. Consequently, the main purpose of this investigation was to study such sensor dynamics (i.e. effect of device location, type and population demographics on energy expenditure estimates) of two commercial activity monitors. It was hypothesized that device location, population studied (disability), choice of proprietary algorithm and type of technology used will significantly impact the accuracy of the predicted physical activity metrics...

BACKGROUND: Alcohol is known to be associated with injury, but little is known of combined use of alcohol and other drugs on injury; especially important for marijuana, given increasing legalization of use in the U.S. and Canada. METHODS: Probability samples of patients 18 and older were interviewed in the emergency department at two sites in Vancouver and one in Victoria, BC (n=1191 injured and 1613 non-injured patients). Case-control and case-crossover analyses were used to analyze risk of injury, based on self-reported alcohol and drug use (marijuana, stimulants, depressants) prior to injury...

OBJECTIVES: Traumatic Brain Injury (TBI) is a common and debilitating injury that is particularly prevalent in patients over 60. Given the influence of head injury on dementia (and vice versa), and the increased likelihood of ground-level falls, elderly patients are vulnerable to TBI. Educational interventions can increase knowledge and influence preventative activity to decrease the likelihood of further TBI. We sought to determine the efficacy of interactive tablet-based educational interventions in elderly patients on self-reported knowledge...

Although limb salvage is now possible for many high-energy open fractures and crush injuries to the distal tibia, ankle, hindfoot, and midfoot, orthotic options are limited. The Intrepid Dynamic Exoskeletal Orthosis (IDEO) is a custom, energy-storing carbon fiber orthosis developed for trauma patients undergoing limb salvage. The IDEO differs from other orthoses in that it allows patients with ankle weakness to have more normal ankle biomechanics and increased ankle power. This article describes the design of a study to evaluate the effectiveness of the IDEO when delivered together with a high-intensity, sports medicine-based approach to rehabilitation...

Cortical neurons remap their receptive fields and rescale sensitivity to spared peripheral inputs following sensory nerve damage. To address how these plasticity processes are coordinated over the course of functional recovery, we tracked receptive field reorganization, spontaneous activity, and response gain from individual principal neurons in the adult mouse auditory cortex over a 50-day period surrounding either moderate or massive auditory nerve damage. We related the day-by-day recovery of sound processing to dynamic changes in the strength of intracortical inhibition from parvalbumin-expressing (PV) inhibitory neurons...

BACKGROUND: Prior studies suggest a link between head injuries and substance use but do not routinely capture mechanisms connecting the two. OBJECTIVES: The goal of the study was to explore whether past head injuries predicted current substance use among young adults, taking factors such as stress, self-esteem, temper, and risk-taking into consideration. METHODS: Data were drawn from a web-based survey conducted in 2014 and 2015 at a public university in the United States (n = 897)...

PURPOSE: The dynamic intraligamentary stabilization (DIS) technique is based on a different treatment approach than ACL reconstruction in that it intends to promote self-healing of the ligament. It is only recommended for acute injuries (<21days). The purpose of the present study was to compare DIS and ACLR with respect to the extent of work incapacity, revision rates, secondary arthroscopies, and treatment costs during recovery. METHODS: The study was a post-hoc analysis of prospectively collected data in the Swiss National Accident Insurance Fund (SUVA) database...

Introduction Operational stress describes individual behavior in response to the occupational demands and tempo of a mission. The stress response of military personnel involved in combat and peace-keeping missions has been well-described. The spectrum of effect on medical professionals and support staff providing humanitarian assistance, however, is less well delineated. Research to date concentrates mainly on shore-based humanitarian missions. Problem The goal of the current study was to document the pattern of operational stress, describe factors responsible for it, and the extent to which these factors impact job performance in military and civilian participants of Continuing Promise 2011 (CP11), a ship-based humanitarian medical mission...

Macrophages represent a key cellular component of the liver, and are essential for maintaining tissue homeostasis and ensuring rapid responses to hepatic injury. Our understanding of liver macrophages has been revolutionized by the delineation of heterogeneous subsets of these cells. Kupffer cells are a self-sustaining, liver-resident population of macrophages and can be distinguished from the monocyte-derived macrophages that rapidly accumulate in the injured liver. Specific environmental signals further determine the polarization and function of hepatic macrophages...

OBJECTIVE: The present study is a systematic review of the literature examining the relationship between alcohol mixed with energy drinks (AmED) and injury. The study provides a summary and critical analysis of the current literature. METHOD: The review was conducted using PRISMA guidelines for systematic reviews. Studies included in the review were those that quantified the relationship between AmED use and injury risk relative to alcohol only. Records were considered along the following theme areas: controlled for drinking behaviors, controlled for impulsivity or risk-taking propensity, examined sex differences, and self-reported injury outcomes for (a) AmED versus alcohol consumers and (b) AmED versus alcohol sessions...

Penile fracture is a relatively rare condition arising from a rupture of the corpus cavernosum. In the western world, it is most commonly associated with sexual intercourse. We hereby, report a rare case of accidental, non-masturbatory, self-inflicted penile fracture. It was diagnosed promptly based on clinical assessment, confirmed radiologically and managed surgically, resulting in a good long-term clinical outcome. Our case highlights the importance of maintaining a high index of suspicion to diagnose this rare condition, even in the absence of a typical mechanism of injury, in order to ensure that such an injury is not missed...

BACKGROUND: Adolescents with previous self-injurious thoughts and behaviors (SITB) have over 2-fold risk of dying by suicide, higher than older ages. This meta-analysis aims to disentangle the association of each SITB with subsequent suicidal behavior in adolescence/young adulthood, the contribution of each SITB, and the proportion of suicide deaths with no previous suicide attempt. METHODS: We searched 6 databases until June 2015. INCLUSION CRITERIA: 1...

Recent research suggests a link between traumatic brain injury (TBI) in youth and later risk behaviour. We explored the association between mild TBI and psychiatric symptoms, substance use and criminal behaviour using data from a longitudinal birth cohort. Participants with mild TBI (n = 800), orthopaedic injuries (n = 2305) and no injuries (n = 8307) were identified from self and parent reports up to age 16 years. Self-report measures of substance use (alcohol, tobacco and cannabis) and criminal behaviours, and parent-reported psychiatric symptoms were collected at age 17 years...

Background Although transcatheter aortic-valve replacement (TAVR) is an accepted alternative to surgery in patients with severe aortic stenosis who are at high surgical risk, less is known about comparative outcomes among patients with aortic stenosis who are at intermediate surgical risk. Methods We evaluated the clinical outcomes in intermediate-risk patients with severe, symptomatic aortic stenosis in a randomized trial comparing TAVR (performed with the use of a self-expanding prosthesis) with surgical aortic-valve replacement...

This article addresses a set of observations framed in both deterministic as well as statistical formal guidelines. It operates within the framework of nonlinear dynamical systems theory (NDS). It is argued that statistical approaches can manifest themselves ambiguously, creating practical discrepancies in psychological and cognitive data analyses both quantitatively and qualitatively. This is sometimes termed in literature as 'questionable research practices.' This communication points to the demand for a deeper awareness of the data 'initial conditions, allowing to focus on pertinent evolution constraints in such systems...

BACKGROUND: Saline, the intravenous fluid most commonly administered to critically ill adults, contains a high chloride content, which may be associated with acute kidney injury and death. Whether using balanced crystalloids rather than saline decreases the risk of acute kidney injury and death among critically ill adults remains unknown. METHODS: The Isotonic Solutions and Major Adverse Renal Events Trial (SMART) is a pragmatic, cluster-level allocation, cluster-level crossover trial being conducted between 1 June 2015 and 30 April 2017 in five intensive care units at Vanderbilt University Medical Center in Nashville, TN, USA...

Xin Ye, Chengfei Zhang
Various clinical studies have revealed that cardiovascular diseases (CVD) are associated with bone loss diseases such as osteoporosis and periodontitis, especially in older population. As one of the best-established risk factors of CVD, hyperlipidemia is also reported to interfere with the metabolism, function and regeneration of mineralized tissues. Derived from postnatal tissue reservoirs, mesenchymal stem cells (MSCs) are considered promising cell sources for mesenchymal and non-mesenchymal tissue regeneration based on their capacities for self-renewal and multi-lineage differentiation as well as potent immunosuppressive effects, secretion of cytokines and regulation of vascularization...
