The prognosis for severe burns has improved significantly over the past 50 years. Meanwhile, burns have become an affliction mainly affecting the less well-developed regions of the world. Early excision and skin grafting has led to major improvements in therapeutic outcomes. Areas covered: The purpose of this article is to survey the use of pharmacotherapy to treat different pathophysiological complications of burn injury. The author, herein, discusses the use of drug treatments for a number of systemic metabolic disturbances including hyperglycemia, elevated catabolism, and gluconeogenesis...

Burns are a frequent cause of traumatic injury, accounting for an average of 1,230 visits to the emergency department every day in the United States. While many of these injuries will heal spontaneously, nearly 1 in 10 are severe enough to require hospitalization or transfer to a specialized burn center. The early surgical management of a severe burn is critical to patient outcome, but few tools exist for triaging viable and non-viable tissue at early time-points post-injury. Without a validated outcome measure, even experienced burn surgeons diagnose tissue viability with an accuracy of only 50-70%, with significant consequences for patient morbidity, mortality and cost to the healthcare system...

Objective: To evaluate vaccination coverage, identify reasons for non-vaccination and assess satisfaction with two innovative strategies for distributing second doses in an oral cholera vaccine campaign in 2016 in Lake Chilwa, Malawi, in response to a cholera outbreak. Methods: We performed a two-stage cluster survey. The population interviewed was divided in three strata according to the second-dose vaccine distribution strategy: (i) a standard strategy in 1477 individuals (68 clusters of 5 households) on the lake shores; (ii) a simplified cold-chain strategy in 1153 individuals (59 clusters of 5 households) on islands in the lake; and (iii) an out-of-cold-chain strategy in 295 fishermen (46 clusters of 5 to 15 fishermen) in floating homes, called zimboweras ...

The next-generation Magnetic Recoil Spectrometer, called MRSt, will provide time-resolved measurements of the deuterium-tritium-neutron spectrum from inertial confinement fusion implosions at the National Ignition Facility. These measurements will provide critical information about the time evolution of the fuel assembly, hot-spot formation, and nuclear burn. The absolute neutron spectrum in the energy range of 12-16 MeV will be measured with high accuracy (∼5%), unprecedented energy resolution (∼100 keV) and, for the first time ever, time resolution (∼20 ps)...

BACKGROUND: Inflammatory response triggered by high mobility group box-1 (HMGB1) protein and oxidative stress play critical roles in the intestinal injury after severe burn. Sodium butyrate, a histone deacetylase inhibitor, has potential anti-inflammatory properties, inhibiting the expression of inflammatory mediators such as HMGB1 in diverse diseases. This study was designed to investigate the effects of sodium butyrate on severe burn plus delayed resuscitation-induced intestine injury, intestinal expressions of HMGB1 and intracellular adhesion molecule-1 (ICAM-1), oxidative stress, and signal transduction pathway changes in rats...

BACKGROUND: The relationship between general practice (GP) supervisors and registrars is a critical component in effective training for the next generation of medical practitioners. Despite the importance of the relational aspect of clinical education, most evaluation has traditionally occurred from the perspective of the registrar only. As such, no validated tools exist to measure the quality of the supervisory relationship from the perspective of the supervisor. This paper presents an adaptation and validation of the clinical psychology supervisory relationship measure (Pearce et al, Br J Clin Psychol 52:249-68, 2013) for GP supervisors in an Australian context...

Airway edema, stenosis, obstruction and even asphyxia are easy to occur in patients with extensive burn, deep burn of head, face, and neck area, inhalation injuries, etc., which threaten life. Timely tracheotomy and intubation is an important treatment measure, but lack of knowledge and improper handling in some hospitals resulted in airway obstruction. The technique of percutaneous tracheotomy and intubation provides convenience for emergency treatment of critical burns and mass burn. The Burn and Trauma Branch of Chinese Geriatrics Society organized some experts in China to discuss the indications, timing, methods, extubation, and precautions of tracheotomy and intubation for burn patients...

Maintenance intravenous fluids (IVFs) are used to provide critical supportive care for children who are acutely ill. IVFs are required if sufficient fluids cannot be provided by using enteral administration for reasons such as gastrointestinal illness, respiratory compromise, neurologic impairment, a perioperative state, or being moribund from an acute or chronic illness. Despite the common use of maintenance IVFs, there is high variability in fluid prescribing practices and a lack of guidelines for fluid composition administration and electrolyte monitoring...

INTRODUCTION:  The development of stenoses after correction of an esophageal atresia or acid and lye burn of the esophagus are well-known problems in pediatric surgery. Currently, stenoses are treated in the majority of cases by repeated balloon dilatations. The diameter of the balloons used is not standardized; standard curves do not exist. The aim of this study was to evaluate the diameter of the esophagus correlated to the body weight of the children as measured in upper gastrointestinal (GI) studies to answer the important question to what extent a stenosis should be dilated...

Local transplantation of stem cells has therapeutic effects on skin damage but cannot provide satisfactory wound healing. Studies on the mechanisms underlying the therapeutic effects of stem cells on skin wound healing will be needed. Hence, in the present study, we explored the role of Caveolin-1 in epidermal stem cells (EpiSCs) in the modulation of wound healing. We first isolated EpiSCs from mouse skin tissues and established stable EpiSCs with overexpression of Caveolin-1 using a lentiviral construct. We then evaluated the epidermal growth factor (EGF)-induced cell proliferation ability using cell counting Kit-8 (CCK-8) assay and assessed EpiSC pluripotency by examining Nanog mRNA levels in EpiSCs...

We explored stroke behaviour, energy sources, and their related metabolic enzymes during multi-intensity swimming and tail-flipping at low- and high-intensity modes in Chinese shrimp Fenneropenaeus chinensis. In swimming, shrimp were encouraged to swim at velocities of 3, 6, 9 cm s-1 for 200 min (low-intensity), and at 12, 15, 18 cm s-1 until fatigue (high-intensity). In tail-flipping, shrimp were encouraged to tail-flip by tapping cephalothorax at frequencies of 0.020, 0.040, 0.063 Hz (one tap every 50, 25, 16 s) for 5 min (low-intensity), and at 0...

Optimizing wellness and health are the most critical goals for patients post solid-organ transplantation. Low health literacy has important implications for wellness and health, increasing patient risk for negative health outcomes. More than 30% of the general US patient population has low health literacy, and solid-organ transplant recipients (SOTRs) may be especially vulnerable to low health literacy and its adverse impact on health outcomes. A comprehensive literature review was conducted and a model was adapted to better depict factors associated with low health literacy...

Fine particulate matters less than 2.5 µm (PM2.5 ) in the ambient atmosphere are strongly associated with adverse health effects. However, it is unlikely that all fine particles are equally toxic in view of their different sizes and chemical components. Toxicity of fine particles produced from various combustion sources (diesel engine, gasoline engine, biomass burning (rice straw and pine stem burning), and coal combustion) and non-combustion sources (road dust including sea spray aerosols, ammonium sulfate, ammonium nitrate, and secondary organic aerosols (SOA)), which are known major sources of PM2...

The prefrontal cortex (PFC) plays a critical role in the control of many physiological processes including attention, learning and decision making (Dalley, Cardinal, & Robbins, 2004; Arnsten & Li, 2005; Funahashi & Andreau, 2013). This brain region receives dopamine (DA) and norepinephrine (NE) axons from the ventral tegmental area (VTA) and locus coeruleus (LC), respectively (Waterhouse, Lin, Burne, & Woodward, 1983; Chandler, Lamperski, & Waterhouse, 2013). Therefore, revealing alterations in catecholamine (CA) dynamics in these circuitries is necessary to understand the pathogenesis of different psychiatric diseases, including addiction to drugs and alcohol...
