Hazardous Materials Incidents (HMIs) have attracted a growing public concern worldwide. The health risks and environmental implications associated with HMIs are almost invariably severe, and underscore the urgency for sound management. Hazardous Materials Explosion incidents (HMEIs) belong to a category of extremely serious HMIs. Existing studies placed focuses predominately on the promptness and efficiency of emergency responses to HMIs and HMEIs. By contrast, post-disaster environmental management has been largely overlooked...

BACKGROUND: The epidemic of human immunodeficiency virus (HIV) infection in Thailand began in 1988 among injection drug users (IDUs) in Bangkok. It soon spread to other populations, especially female sex workers (FSWs) and men attending STD clinics. Routine serologic surveillance for HIV began among military conscripts in 1991. The HIV seroprevalence data from military conscripts provided national surveillance data, since the entire population of 21 year old men were conscripted for 2 years' service in the military by a random process during which 10% of men were selected...

INTRODUCTION: The incidence and treatment of cancer in HIV-infected children from resource-limited settings has not been extensively studied. OBJECTIVES: Develop and implement a cross-sectional survey to evaluate pediatric cancer burden, diagnostic modalities in use, and treatment availability as perceived by HIV clinic staff at regional International Epidemiology Databases to Evaluate AIDS (IeDEA) sites. METHODS: IeDEA regional investigators developed a cross-sectional clinical site survey which included questions on the numbers and types of pediatric cancers observed, modalities used to treat identified cancers and treatment options available at individual sites in the Asia-Pacific, Latin America, Central Africa, East Africa, West Africa, and Southern Africa regions...

Background: The variability in risk tolerance in medicine is not well understood. Parallels are often drawn between aviation and anaesthesia. The aviation industry is perceived as culturally risk averse, and part of preflight checks involves a decision on whether the flight can operate. This is sometimes termed a go/no-go decision. This questionnaire study was undertaken to explore the equivalent go/no-go decision in anaesthesia. We presented anaesthetists with a range of situations in which additional risk might be expected and asked them to decide whether they would proceed with the case...

Under hypotonic conditions, the regulatory volume decrease (RVD) is essential to maintain physiological homeostasis and functions in diverse biological systems. Intracellular Ca(2+) has been reported as an important mediator of this response, but the underlying Ca(2+) mechanism responsible for RVD is still controversial. Here we investigate the role of Ca(2+) in the RVD response using live-cell imaging, microspectrofluorimetry, and a patch-clamp technique. A typical RVD was observed in submandibular gland acinar cells after swelling in a hypotonic solution, whereas intracellular Ca(2+) chelation completely inhibited the RVD response...

Monitoring of the time-varying immune status of a diseased host often requires rapid and sensitive detection of cytokines. Metallic nanoparticle-based localized surface plasmon resonance (LSPR) biosensors hold promise to meet this clinical need by permitting label-free detection of target biomolecules. These biosensors, however, continue to suffer from relatively low sensitivity as compared to conventional immunoassay methods that involve labeling processes. Their response speeds also need to be further improved to enable rapid cytokine quantification for critical care in a timely manner...

Apathy and impulsivity are common and disabling consequences of frontotemporal lobar degeneration. They cause substantial carer distress, but their aetiology remains elusive. There are critical limitations to previous studies in this area including (i) the assessment of either apathy or impulsivity alone, despite their frequent co-existence; (ii) the assessment of behavioural changes within single diagnostic groups; and (iii) the use of limited sets of tasks or questions that relate to just one aspect of these multifactorial constructs...

BACKGROUND: The introduction of rapid response systems has reduced the incidence of in-hospital cardiac arrest; however, many instances of clinical deterioration are unrecognised. Afferent limb failure is common and may be associated with unplanned intensive care admissions, heightened mortality and prolonged length of stay. Patients reviewed by a Medical Emergency Team are inherently vulnerable with a high in-hospital mortality. OBJECTIVE: To explore perceptions of intensive care unit (ICU) staff who attend deteriorating acute care ward patients regarding current problems, barriers and potential solutions to recognising and responding to clinical deterioration that culminates in a Medical Emergency Team review...

A right-hook crash is a crash between a right-turning motor vehicle and an adjacent through-moving bicycle. At signalized intersections, these crashes can occur during any portion of the green interval when conflicting bicycles and vehicles are moving concurrently. The objective of this research was to evaluate the effectiveness of four types of engineering countermeasures - regulatory signage, intersection pavement marking, smaller curb radius, and protected intersection design - at modifying driver behaviors that are known contributing factors in these crashes...

Head and neck squamous cell carcinoma (HNSCC) is the sixth leading cancer by incidence worldwide and considering the recent EUROCARE-5 population-based study the 5-year survival rate of HNSCC patients in Europe ranges between 69% in localized cases and 34% in patients with regional involvement. The development of high-throughput gene expression assays in the last two decades has provided the invaluable opportunity to improve our knowledge on cancer biology and to identify predictive signatures in the most deeply analyzed malignancies, such as hematological and breast cancers...

Without an engineering risk assessment for emergency disposal in response to sudden water pollution incidents, responders are prone to be challenged during emergency decision making. To address this gap, the concept and framework of emergency disposal engineering risks are reported in this paper. The proposed risk index system covers three stages consistent with the progress of an emergency disposal project. Fuzzy fault tree analysis (FFTA), a logical and diagrammatic method, was developed to evaluate the potential failure during the process of emergency disposal...

BACKGROUND: Infants are the most likely recipients of child welfare services; however, little is known about infants and families who come into contact with the child welfare system and factors that are associated with service provision. Investigations involving infants and their families present an unparalleled opportunity for the child welfare sector to enhance infants' safety and well-being through early identification, referral and intervention. Understanding how the child welfare system responds to the unique needs of infants and caregivers is critical to developing appropriate practice and policy responses within the child welfare sector and across other allied sectors...

BACKGROUND: New onset atrial fibrillation (AF) in critically ill surgical patients is associated with significant morbidity and increased mortality. N-terminal pro-B type natriuretic peptide (NT-proBNP) is released by cardiomyocytes in response to stress and may predict AF development after surgery. We hypothesized that elevated NT-proBNP level at surgical ICU admission predicts AF development in a general surgical and trauma population. METHODS: From July to October 2015, NT-proBNP concentrations were measured at ICU admission...

Rituximab is a plausible alternative first-line treatment of ANCA-associated vasculitis. Adverse effects related to its infusion are common and usually have a benign course. However, there have been reports of refractory cardiogenic shock simulating septic shock. We report an 81-year-old male with the diagnosis of ANCA associated vasculitis. Rituximab 500 mg was administered intravenously for a relapse. The infusion proceeded without incident. However, 24 hours after its administration the patient began with fever, chills, coughing and strong malaise...

Sleep disorders are a critical issue for the military, as they impact operational readiness, personnel health, wellbeing and health-care costs. The incidence of insomnia and obstructive sleep apnea (OSA) are increasing in the United States civilian population, and rates in military personnel exceed those of civilians. Using a comprehensive database, rates of medical encounters for insomnia and OSA were investigated and their associations with various demographic factors examined in the total US military population [1,381,406 ± 25,123, mean ± standard deviation (SD) personnel per year] from 2005 to 2014...

BACKGROUND: Epidemiological, clinical, and high-risk studies have provided evidence that the peak period for onset of diagnosable episodes of mania and hypomania starts in mid-to-late adolescence. Moreover, clinically significant manic symptoms may occur even earlier, especially in children at familial risk. Lithium is the gold standard treatment for acute mania in adults, yet to our knowledge, there is no published systematic review assessing lithium treatment of mania in children or adolescents...

The purpose of this article is to describe the usability and human factors engineering standards used in development of a sepsis alert known as the sepsis prompt. Sensory processing, cognitive processing, signal detection, criterion response, and user satisfaction were evaluated with controlled user testing and critical incident response techniques. Nurses reported that the sepsis prompt was visible and distinct, making it easily detectable. The prompt provided a clear response mechanism and adequately balanced the number of false alerts with the likelihood of misses...

Toll-like receptor (TLR) 2 plays a critical role in host defenses against mycobacterial infections. The Arg753Gln (R753Q) TLR2 polymorphism has been associated with increased incidence of tuberculosis and infections with non-tuberculous mycobacteria in human populations, but the mechanisms by which this polymorphism affects TLR2 signaling are unclear. In this study, we determined the impact of the R753Q TLR2 polymorphism on macrophage sensing of Mycobacterium smegmatis. Upon infection with M. smegmatis, macrophages from knock-in (KI) mice harboring R753Q TLR2 expressed lower levels of TNF-α, IL-1β, IL-6 and IL-10 compared to cells from wild-type (WT) mice but both R753Q TLR2 and WT mice exhibited comparable bacterial burdens...

We theoretically studied in terahertz frequency regime optical bistability of graphene placed at the interface between thin dielectric layers. We solved self-consistently the nonlinear wave equations containing the third-order optical conductivity of graphene in four-layer structures and obtained hysteresis response of the transmitted power as a function of the incident power. We numerically observed that the critical powers for the up and down transitions and the Fermi-energy of graphene required for terahertz optical bistability can be reduced by carefully choosing material properties and the thicknesses of dielectric layers...

INTRODUCTION: Over the past 15 years, violent threats and acts against hospital patients, staff, and providers have increased and escalated. The leading area for violence is the emergency department (ED) given its 24/7 operations, role in patient care, admissions gateway, and center for influxes during acute surge events. This investigation had three objectives: to assess the current security of Washington State EDs; to estimate the prevalence of and response to threats and violence in Washington State EDs; and to appraise the Washington State ED security capability to respond to acute influxes of patients, bystanders, and media during acute surge events...
