Many emergency departments have implemented sepsis protocols since the 2001 publication of results from the early goal-directed therapy trial, which showed early targeted resuscitation lowers mortality. As part of an attempt to improve clinical and operational outcomes for emergency departments across British Columbia, we reviewed sepsis management literature and considered sepsis protocol implementation in the province’s emergency departments. During the literature review we found that many observational studies confirmed an association between implementation of emergency sepsis protocols and decreased mortality...

Mercury is a globally distributed toxicant to aquatic animals and mammals. However, the potential risks of environmental relevant mercury in terrestrial systems remain largely unclear. The metabolic profiles of the earthworm Eisenia fetida after exposure to soil contaminated with mercury at 0.77 ± 0.09 mg/kg for 2 weeks were investigated using a two-dimensional nuclear magnetic resonance-based (1 H-13 C NMR) metabolomics approach. The results revealed that traditional endpoints (e.g., mortality and weight loss) did not differ significantly after exposure...

The process of extracting hydrocarbon resources by hydraulic fracturing is an increasingly utilised technique worldwide, resulting in an effluent called flowback and produced water (FPW). This effluent is a complex mixture of salts, metals and organic compounds, and has been shown to be highly toxic to aquatic biota, an effect attributed mainly to its salt and organic components. However, in the current study we show that the water flea, Daphnia magna, is physically impaired by, and rendered immobile at the surface of, test waters containing FPW...

Investigating how well people adapt to heat waves and cold spells has been an important issue under climate change. Also, most of previous studies focused only on the mortality risks for heat waves or cold spells for certain time period not considering its temporal changes and increasing frequencies. This study investigated the change in risks of mortality from heat waves and cold spells over time, and estimated the temporal changes in mortality burden attributed to heat waves and cold spells in Korea and Japan...

AIMS: Porcelain-fused-to-metal (PFM) crowns are a standard restoration technique in dentistry, but toxicity of PFM in vivo has not been systematically evaluated. The present study evaluated the effects of various metal alloy shells of PFM crowns on the development of zebrafish embryos and larvae in order to determine the safety of these materials. MAIN METHODS: Gold palladium (Au-Pd), silver palladium (Ag-Pd), Nickel chromium (Ni-Cr), cobalt chromium (Co-Cr), titanium (Ti) alloy porcelain crowns were immersed in artificial saliva for 1, 4, and 7 weeks, and the leach solution was collected and used to treat zebrafish embryos at 4-144 h PFM...

BACKGROUND: In patients with hypertrophic cardiomyopathy (HCM), enlargement of the left atrium (LA) is associated with increased morbidity and mortality due to risk of atrial fibrillation (AF), stroke, and heart failure. In this study, we investigated whether LA reverse remodeling occurs following septal myectomy. METHODS: Between March 2007 and July 2015, 656 patients underwent myectomy at our institution and had pre- and postoperative transthoracic echocardiographic (TTE) recording of LA volume index (LAVI)...

Bottom fishing such as trawling and dredging may pose serious risks to the seabed and benthic habitats, calling for a quantitative assessment method to evaluate the impact and guide management to develop mitigation measures. We provide a method to estimate the sensitivity of benthic habitats based on the longevity composition of the invertebrate community. We hypothesize that long-lived species are more sensitive to trawling mortality due to their lower pace of life (i.e. slower growth, late maturation). We analyse data from box-core and grab samples taken from 401 stations in the English Channel and southern North Sea to estimate the habitat-specific longevity composition of the benthic invertebrate community and of specific functional groups (i...

Lung cancer is one of the most lethal cancers in the USA. In 2013, new guidelines issued by the United States Preventive Services Task Force recommended lung cancer screening using low-dose computed tomography among a selected group of high-risk individuals. Specifically, lung cancer screening is recommended for heavy smokers between the ages of 55 to 79, with at least 30 pack-year smoking exposure. Former smokers who meet these guidelines and stopped smoking ≤ 15 years ago are also eligible. There is a need to promote lung cancer screening to increase early diagnosis rates and treatment options, thereby decreasing disease-specific mortality...

Accumulating evidence suggests that pesticides have played a role in the increased rate of honeybee colony loss. One of the most commonly used pesticides in the US is the neonicotinoid imidacloprid. Although the primary mode of action of imidacloprid is the insect nervous system, it has also been shown to cause changes insects' digestive physiology, and alter the microbiota of Drosophila melanogaster larvae. The honey bee gut microbiome plays a major role in bee health. Although many studies have shown that imidacloprid affects honey bee behavior, its impact on the microbiome has not been fully elucidated...

Secondary acute myeloid leukemia (sAML) has been associated with inferior outcomes compared to de novo AML. Little is known about patient risk factors and outcomes in sAML after allogeneic hematopoietic stem cell transplantation (HCT), thus this large systemic analysis of the EBMT registry was performed. This study included 4997 patients with sAML who received HCT from 2000-2016. In univariate analysis, the 2-year cumulative incidence of chronic graft versus host disease (GVHD), relapse (RI), and non-relapse mortality (NRM) were 33...

BACKGROUND: Current European Society of Cardiology Guidelines recommend concomitant atrial fibrillation (AF) ablation for all symptomatic patients undergoing other cardiac surgeries, but the safety and potential benefits of concomitant atrial fibrillation (AF) ablation at the time of double valve replacement (DVR: aortic and mitral valve replacement) remains unexamined. MATERIALS AND METHODS: We conducted a retrospective review of 238 patients with AF who underwent DVR with or without concomitant surgical ablation (Ablation group, n=113; Non-ablation group, n=125) at a single institute from April 2006 to September 2011...

REVIEW
Mai-Britt Worm Ørntoft
Colorectal cancer (CRC) is a leading cause of cancer related deaths worldwide, and late stages (III-IV) in particular have low 5-year survival rates. Stage shifting by CRC screening programs has proven effective by decreasing morbidity and mortality and in many countries national CRC screening programs have been implemented. Currently, European, Asian, and American authorities recommend screening for CRC using fecal occult blood testing, sigmoidoscopy, or colonoscopy. Because these approaches all have weaknesses (eg, poor compliance, high costs, test invasiveness), much effort has been put into the development of alternative screening approaches, many of which are blood-based...

BACKGROUND: Preventing death is the most important outcome pursued in the Emergency Department. Prompt accurate assessment, followed by competent and efficient investigation and treatment is the recipe sought. Abnormal physiological measurements are common antecedents to deterioration and therefore a cornerstone in many risk stratification tools. Some risk factors have their impact during the first few days after admittance, others have higher impact on 30 day mortality. Understanding the variance in impact of risk factors is relevant for future composition of risk stratification models...

BACKGROUND: The donation rate (DR) per million population is not ideal for an efficiency comparison of national deceased organ donation programs. The DR does not account for variabilities in the potential for deceased donation which mainly depends on fatalities from causes leading to brain death. In this study, the donation activity was put into relation to the mortality from selected causes. Based on that metric, this study assesses the efficiency of different donation programs. METHODS: This is a retrospective analysis of 2001-2015 deceased organ donation and mortality registry data...
