Occurrence, dispersal, and associated environmental risk assessment of pesticides and their transformation products in small water bodies of Northeastern France.

The widespread use of pesticides, specifically plant protection products (PPPs), has led to their transformation products (TPs) being increasingly detected in various environmental compartments, notably surface waters. This study integrates field-detected TPs into an environmental risk assessment of lentic small water bodies (LSWBs). For this purpose, measured environmental concentrations (MECs) of PPPs and TPs in 12 LSWBs, influenced by tributaries under varying agricultural pressures, were collected.

Governing taste: data, temporality and everyday kiwifruit dry matter performances.

Data is essential to governing those emerging matters of concern that confront the agrifood every day. But data is no neutral intermediary. It disrupts, exposes, and creates new social, economic, political, and environmental possibilities, whilst simultaneously hiding, excluding, and foreclosing others.

Determination of nitroaromatic explosive residues in water by stir bar sorptive extraction-gas chromatography-tandem mass spectrometry.

Nitroaromatic compounds were massively used in the formulation of explosives during both world wars. Even several decades after the end of these wars, their residues are suspected to be widely present in the environment. Their occurrence and effect on ecosystems and human health are still not fully determined.

The goal of this study was to determine the potential exposure of much of the French population to nine phthalates and bis (2-ethylhexyl) adipate (DEHA) due to water consumption. The occurrence of these compounds was investigated in raw and treated water from public water systems. Water samples were collected in one sampling campaign equally distributed across 101 French départements (a French administrative unit) from November 2015 to July 2016.

GC-IMS headspace analyses allow early recognition of bacterial growth and rapid pathogen differentiation in standard blood cultures.

Outcome of patients with blood stream infections (BSI) depends on the rapid initiation of adequate antibiotic therapy, which relies on the fast and reliable identification of the underlying pathogen. Blood cultures (BC) using CO-sensitive colorimetric indicators and subsequent microbiological culturing are the diagnostic gold standard but turnaround times range between 24 and 48 h. The detection of volatile organic compounds of microbial origin (mVOC) has been described as a feasible method for identifying microbial growth and to differentiate between several microbial species.

Clinical Scores and Formal Triage for Screening of Sepsis and Adverse Outcomes on Arrival in an Emergency Department All-Comer Cohort.

Background: Early recognition of sepsis remains a major challenge. The clinical utility of the Quick Sepsis-Related Organ Failure Assessment (qSOFA) score is still undefined. Several studies have tested its prognostic value.

Impact of Initial Antifungal Therapy on the Outcome of Patients With Candidemia and Septic Shock Admitted to Medical Wards: A Propensity Score-Adjusted Analysis.

Background: Echinocandins are recommended as firstline therapy in patients with candidemia. However, there is debate on their efficacy in survival outcomes. The aim of this study is to evaluate whether the choice of initial antifungal therapy improves mortality in patients with candidemia in relation to the presence of septic shock.

Impact of gadolinium-based contrast agents on the growth of fish cells lines.

The present study was the first approach conducted under environmental concentrations of Gd-DOTA and Gd-DTPA-BMA to assess cellular impacts of these compounds. Gd-DOTA (Gadoteric acid) is one of the most stable contrast agent, currently used as Dotarem formulation during Magnetic Resonance Imaging exams. The study was mainly performed on a Zebra Fish cell line (ZF4; ATCC CRL-2050).

Poly- and Perfluoroalkyl Substances in Runoff Water and Wastewater Sampled at a Firefighter Training Area.

Per- and polyfluoroalkyl substances (PFASs) are key ingredients of firefighting foams designed to suppress fires involving flammable and combustible liquids. Such foams are used by firefighters during fire training at dedicated sites. Because PFASs are very persistent chemicals, substantial soil and groundwater contamination has been observed in the vicinity of firefighter training areas.

Variations of anthropogenic gadolinium in rivers close to waste water treatment plant discharges.

Rare earth element (REE) concentrations were determined for 22 sites sampled during two water periods: high flow in winter and low flow in summer. Shale-normalized REE patterns of all samples displayed positive gadolinium (Gd) anomalies. They revealed a widespread contamination of anthropogenic Gd (Gd) from waste water treatment plant (WWTP) outputs to catchment areas used for drinking water.

Deep seepage of per- and polyfluoroalkyl substances through the soil of a firefighter training site and subsequent groundwater contamination.

Per- and polyfluoroalkyl substances (PFASs) are utilized in specific firefighting foams. The objectives of this study were i) to map PFAS distribution in the soil and groundwater of a firefighter training site active for more than 3 decades, ii) to locate the main points of entry of PFASs into the aquifer and iii) to identify which PFASs seeped most deeply into the soil. A total of 44 soil cores and 17 groundwater samples were collected.

Herpes simplex virus (HSV) pneumonia in the non-ventilated immunocompromised host: Burden and predictors.

Objectives: To evaluate burden and predictors of HSV pneumonia among immunocompromised patients not undergoing invasive mechanical ventilation according to a tailored diagnostic algorithm.

Methods: This prospective, observational study included immunocompromised adults with pneumonia non-responding to empirical antibiotic therapy. Bronchoalveolar lavage (BAL) specimens were cultured for bacteria, mycobacteria and fungi.

Exploring the influence of natural cosolvents on the free energy and conformational landscape of filamentous actin and microtubules.

Actin and tubulin, the main components of the cytoskeleton, are responsible for many different cellular functions and can be found in nearly all eukaryotic cells. The formation of filamentous actin (F-actin) as well as microtubules depends strongly on environmental and solution conditions. The self-assembly of both, actin and tubulin, has been found to be among the most pressure sensitive process in vivo.

Is fish embryo test (FET) according to OECD 236 sensible enough for delivering quality data for effluent risk assessment?

Over the past few years, the fish embryo test (FET) has become widely accepted as an animal-friendly protocol for ecotoxicological research. As Organisation for Economic Co-operation and Development (OECD) 236, the FET has been widely applied for simple mixture exposures under the Registration, Evaluation, Authorisation, and Restriction of Chemicals regulation of the European Union; and now its use is spreading worldwide as a supposedly reliable whole-effluent test (i.e.

Treatment of dizziness: an interdisciplinary update.

Dizziness in the emergency department: an update on diagnosis.

This review aims to assist emergency physicians in finding the underlying aetiology when a patient presents with dizziness to the emergency department. After reading this review, the emergency physician will be able to consider the most relevant differential diagnoses and have an idea about dangerous aetiologies that require immediate action. The emergency physician will also know what diagnostic steps need to be taken at what time, such as the three-component HINTS Test (Head Impulse, Nystagmus, and Test-of-Skew), which helps with distinguishing central from peripheral causes of the acute vestibular syndrome.

Determination of pharmaceutical compounds in hospital wastewater and their elimination by advanced oxidation processes.

This study investigates the mineralization efficiency, i.e. removal of total organic carbon (TOC) in hospital wastewater by direct ozonation, ozonation with UV radiation (O/UV), homogeneous catalytic ozonation (O/Fe) and homogeneous photocatalytic ozonation (O/Fe/UV).

Ecological consequences of forest elephant declines for Afrotropical forests.

Poaching is rapidly extirpating African forest elephants (Loxodonta cyclotis) from most of their historical range, leaving vast areas of elephant-free tropical forest. Elephants are ecological engineers that create and maintain forest habitat; thus, their loss will have large consequences for the composition and structure of Afrotropical forests. Through a comprehensive literature review, we evaluated the roles of forest elephants in seed dispersal, nutrient recycling, and herbivory and physical damage to predict the cascading ecological effects of their population declines.

Per- and polyfluoroalkyl substances in firefighting foam concentrates and water samples collected near sites impacted by the use of these foams.

To extinguish large-scale fuel fires, fluorosurfactant based foams (FSBFs) were developed in the 1960s and have been used ever since. In this study, 154 per- and polyfluoroalkyl substances (PFASs) including 122 emerging PFASs used as surfactants in FSBFs were sought in nine different foam concentrates. Field investigations were also carried out in the vicinity of four sites where FSBFs are or were intensively used (two airports, a training center for firefighters and an oil storage depot after a large explosion).

Bioaccumulation of gadolinium in freshwater bivalves.

In this study, the presence of anthropogenic gadolinium (Gd) was evaluated in rivers, close to wastewater treatment plant outputs. Then, one site was selected for in situ experiments to assess the bioaccumulation of Gd in the digestive gland and in the gills of two bivalves (Dreissena rostriformis bugensis and Corbicula fluminea). For both organisms, the results suggested that the bioaccumulation of Gd can be observed when organisms are exposed in a geogenic and anthropogenic Gd mixture.

Comparison of different advanced oxidation processes for the removal of amoxicillin in aqueous solution.

Amoxicillin (AMX) is a widely used penicillin-type antibiotic whose presence in the environment has been investigated. In this work, the degradation of the AMX in aqueous solutions by ozonation, ozonation with UV radiation (O/UV), homogeneous catalytic ozonation (O/Fe) and homogeneous photocatalytic ozonation (O/Fe/UV) was investigated. The performance results have been compared in terms of removal of amoxicillin and total organic carbon (mineralization efficiency).

Validation of a method to monitor the occurrence of 20 relevant pharmaceuticals and personal care products in 167 bottled waters.

Research on emerging substances in drinking water presents major interest and the possibility of trace contamination has seen increasing concern from the scientific community and the public authorities. More particularly, residues of pharmaceuticals and personal care products (PPCPs) in bottled water are a very important issue due to societal concerns and potential media impact. In this context, it has become necessary to carry out reliable monitoring.

Poaching empties critical Central African wilderness of forest elephants.

Elephant populations are in peril everywhere, but forest elephants in Central Africa have sustained alarming losses in the last decade [1]. Large, remote protected areas are thought to best safeguard forest elephants by supporting large populations buffered from habitat fragmentation, edge effects and human pressures. One such area, the Minkébé National Park (MNP), Gabon, was created chiefly for its reputation of harboring a large elephant population.
