Firefighters' skin may be exposed to chemicals via permeation/penetration of combustion byproducts through or around personal protective equipment (PPE) or from the cross-transfer of contaminants on PPE to the skin. Additionally, volatile contaminants can evaporate from PPE following a response and be inhaled by firefighters. Using polycyclic aromatic hydrocarbons (PAHs) and volatile organic compounds (VOCs) as respective markers for non-volatile and volatile substances, we investigated the contamination of firefighters' turnout gear and skin following controlled residential fire responses...

BACKGROUND: Medication errors are a frequent problem in the accident and emergency (A&E) department. CASE DESCRIPTION: A 17-year-old boy was referred to our A&E department with an anaphylactic reaction to peanuts. Because of various shortcomings in the care process in A&E, adrenaline was administered intravenously instead of intramuscularly, resulting in a broad complex tachycardia. We analysed these shortcomings using the 'Prevention and recovery information system for monitoring and analysis' (PRISMA) method...

OBJECTIVE: To assess the association between plasma ceramides and hepatic steatosis (HS) in adolescents, independently of obesity. MATERIALS AND METHODS: Ninety-four adolescents from two previous studies conducted and published by our crew were included. Study subjects were stratified in three groups: normal weight (n = 18), obesity (n = 34), and obesity + HS (n = 42). The presence of HS was defined when ALT/AST ratio was <1. Ceramides subspecies (C14:0, C16:0, C18:0, C24:0, and C24:1) were determined by LC/MS...

In commemoration of one hundred years of the beginning of World War I, the occurrence of an outbreak of trichinosis in the crew of the SMS Dresden, a German ship that participated in that world conflagration, is re-viewed. In September 1915, while the sailors of SMS Dresden were forcibly detained on Isla Quiriquina, Bío Bío Region, Chile, 60 individuals became ill. The cause of the outbreak was the consumption of sausages made from pork infected with the parasite Trichinella spiralis. There was a fatal case...

Dialysis initiation rates among older adults, aged 75 years or greater, are increasing at a faster rate than for younger age groups. Older adults with advanced CKD (eGFR < 30 ml/min/1.73 m(2)) typically lose renal function slowly, often suffer from significant comorbidity and thus may die from associated comorbidities before they require dialysis.A patient's pattern of renal function loss over time in relation to their underlying comorbidities can serve as a guide to the probability of a future dialysis requirement...

Women with atypical hyperplasia (AH) and lobular or ductal carcinoma in situ (LCIS/DCIS) are at increased risk of developing invasive breast cancer. Chemoprevention with selective estrogen receptor modulators or aromatase inhibitors can reduce breast cancer risk; however, uptake is estimated to be less than 15% in these populations. We sought to determine which factors are associated with chemoprevention uptake in a population of women with AH, LCIS, and DCIS. Women diagnosed with AH/LCIS/DCIS between 2007 and 2015 without a history of invasive breast cancer were identified (n=1719)...

One of the major challenges in big cities is planning and implementation of an optimized, integrated solid waste management system. This optimization is crucial if environmental problems are to be prevented and the expenses to be reduced. A solid waste management system consists of many stages including collection, transfer and disposal. In this research, an integrated model was proposed and used to optimize two functional elements of municipal solid waste management (storage and collection systems) in the Ahmadabad neighbourhood located in the City of Mashhad - Iran...

REVIEW
Kanak Raina, Craig M Crews
Small molecule probes of biological systems have traditionally been designed to bind to and inhibit the active sites of their protein targets. While this class of pharmacological agents has been broadened by the development of a small number of allosteric and protein-protein interaction (PPI) inhibitors, conventional drug design still excludes 'undruggable' proteins that are neither enzymes nor receptors. Recent years have seen the emergence of new classes of small molecules that can target hitherto undruggable proteins by recruiting the cellular proteostasis machinery to selectively tag them for degradation...

A 75-year-old man collapsed on a golf course and received cardiopulmonary resuscitation from a bystander, including the use of a public automated external defibrillator (AED). The AED was discharged once, with return of spontaneous circulation. An air ambulance crew found the patient haemodynamically stable, with no acute abnormalities on a 12-lead ECG. He had reduced consciousness and a dilated left pupil. On contacting the patient's wife by telephone, she said that he had fallen and hit his head earlier that day...

Multimodal polymeric nanoparticles have many exciting diagnostic and therapeutic applications, yet their uptake and passage by the placenta, and applications in the treatment of pregnancy complications have not been thoroughly investigated. In this work, the maternal-fetal-placental biodistribution of anionic and cationic multimodal poly(glycidyl methacrylate) (PGMA) nanoparticles in pregnant rats at mid (ED10) and late (ED20) gestation was examined. Fluorescently-labelled and superparamagnetic PGMA nanoparticles functionalized with/without poly(ethyleneimine) (PEI) were administered to pregnant rats at a clinically-relevant dose and biodistribution and tissue uptake assessed...

During a 2-month mission in Southeast Asia, including numerous stopovers in coastal cities, the crew of a frigate of the French Navy received doxycycline for antimalarial prophylaxis. Adherence to this chemoprophylaxis was evaluated with an anonymous questionnaire distributed at the end of the malaria exposure period. The response rate was 74 % (72 crew members). Among them, 67 sailors felt they had received clear information about the risks of malaria. Overall, 19 (27 %) respondents reported adherence (one forgotten pill, by no more than 15 days), 18 (25 %) irregular adherence (one or more pills forgotten weekly or stopped during the mission), and 35 recognized that they had not taken the treatment...

In space, living organisms are exposed to multiple stress factors including microgravity and space radiation. For humans, these harmful environmental factors have been known to cause negative health impacts such as bone loss and immune dysfunction. Understanding the mechanisms by which spaceflight impacts human health at the molecular level is critical not only for accurately assessing the risks associated with spaceflight, but also for developing effective countermeasures. Over the years, a number of studies have been conducted under real or simulated space conditions...

The existence of the adenoid first appears to have been noted by Conrad Victor Schneider in 1661. James Yearsley reported in 1842 one case in which he improved hearing by removal of a mucus membrane from behind the uvula, which indicates some appreciation of a relationship of the nasopharynx to ear disease. Hans Wilhelm Meyer, in 1868, was the first to demonstrate the relationship of the adenoid to ear disease and to develop an effective, although somewhat difficult, surgical operation to remove the adenoid...

Cyclooxygenase-2 catalyses the biosynthesis of prostaglandins from arachidonic acid but also the biosynthesis of prostaglandin glycerol esters (PG-Gs) from 2-arachidonoylglycerol. Previous studies identified PG-Gs as signalling molecules involved in inflammation. Thus, the glyceryl ester of prostaglandin E2, PGE2-G, mobilizes Ca(2+) and activates protein kinase C and ERK, suggesting the involvement of a G protein-coupled receptor (GPCR). To identify the endogenous receptor for PGE2-G, we performed a subtractive screening approach where mRNA from PGE2-G response-positive and -negative cell lines was subjected to transcriptome-wide RNA sequencing analysis...

BACKGROUND: Sailors in the U.S. Navy are habitual shiftworkers, often experiencing circadian misalignment due to their irregular work/rest schedules. This study assessed the effect of sunlight exposure, work hours, and caffeinated beverage consumption on the daily sleep duration of crewmembers of a U.S. Navy ship during a 2-wk underway period. METHODS: Working in an artificially lit area with no access to sunlight during work hours, U.S. Navy crew members (N = 91) used daily logs to report their daily activity, caffeinated beverage consumption, and exposure to sunlight while off-duty; sleep was assessed by wrist-worn actigraphy...
