Pharmaceuticals in processing of municipal sewage sludge studied by grab and passive sampling

2018

Abstract Concentrations of pharmaceuticals, consisting of four anti-inflammatory and one antiepileptic drug, were studied in the aqueous and solid phase of municipal sewage sludge, collected from a wastewater treatment plant (WWTP) in central Finland. The samples included untreated municipal sludge from the biological wastewater treatment, digested sludge and sludge before and after composting. First, samples were taken as grab samples to study the bioavailable part in aqueous phase but also the part in solid fraction. Later, the long-term concentrations were studied by passive sampling with styrene divinylbenzene-reverse phase sulfonated (SDB-RPS) disks. In the untreated solid sludge, the …

The role of collective action for the emergence and consolidation of democracy

2020

AbstractThe role of citizens' collective action for the emergence and consolidation of democracy is generally analysed within bottom-up theories. However, top-down theories show that elites might impede or promote both democracy and collective action through a set of strategies which are often unobserved and vary over time. Democratic persistence and change require then to be assessed in a dynamic framework which considers both citizens and elites' strategies. For such reason, on a large sample of countries in the period 1971–2014, we jointly estimate the probability of collective action and democracy using a Structural Dynamic Model. This allows us to account for the dynamic nature of the …

Who can best report on children's motor competence: Parents, teachers, or the children themselves?

2018

Abstract Objective A positive perception of motor competence (MC) is important for children's health trajectory. It is purported that young children's perception is not well aligned with their actual ability. Alternative sources of perceptions are postulated from children's social context such as their parents or teachers. This study aims to analyse the associations among children's, parents' and Physical Education (PE) teachers' perception of children's MC and the children's actual MC, and whether these sources of information can report on children's actual MC. Design and method A convenience sample of 139 typically developed children (48.2% girls) from six schools participated in this cro…

This study aimed to investigate how children with attention deficit hyperactivity disorder (ADHD) adjust to school when compared to typically developing students. The convenience sample consisted o...

Tips and tricks for flow cytometry-based analysis and counting of microparticles

2015

Submicron-sized extra-cellular vesicles generated by budding from the external cell membranes, microparticles (MPs) are important actors in transfusion as well as in other medical specialties. After briefly positioning their role in the characterization of labile blood products, this technically oriented chapter aims to review practical points that need to be considered when trying to use flow cytometry for the analysis, characterization and absolute counting of MP subsets. Subjects of active discussions relative to instrumentation will include the choice of the trigger parameter, possible standardization approaches requiring instrument quality-control, origin and control of non-specific ba…

Distrés psicológico en adolescentes víctimas de cyberbullying || Psychological distress among adolescents victims of cyberbullying

2017

Las tecnologías de la información y la comunicación se han incorporado y extendido rápidamente en nuestra sociedad. Actualmente, los niños y adolescentes acceden en edades cada vez más tempranas a los dispositivos electrónicos. A pesar de las grandes ventajas que tienen las tecnologías de la información y la comunicación, las tecnologías también pueden ser utilizadas de manera inapropiada para intimidar y molestar a los iguales, causando graves daños psicológicos en las víctimas. Desde esta perspectiva, el principal objetivo del presente estudio ha sido comprobar el distrés psicológico en una muestra de adolescentes víctimas de cyberbullying. Para ello se midieron las variables: sintomatolo…

Diagnostic and prognostic value of H-FABP in acute coronary syndrome: Still evidence to bring

2018

Abstract The assessment of chest pain patients presenting to the emergency area (EA) is still a clinical challenge, as the majority of patients are not diagnosed with acute coronary syndrome (ACS). New generation high sensitivity c-Tn (hs-cTn) assays have showed better performances compared to the standard c-Tn. However, hs-Tn still presents some limitations. Hence, novel, early biomarkers are needed in this setting. Among all, heart-type fatty acid binding protein (H-FABP) has been largely investigated. This article reviews the studies evaluating H-FABP performance in diagnosing acute myocardial infarction (AMI) and stratifying chest pain patients by risk. H-FABP optimal performances in AC…

Air pollution and airport apron workers: A neglected occupational setting in epidemiological research.

2020

Abstract Introduction Airport apron workers are occupationally exposed to jet exhaust and major concern is related to the exposure to ultrafine particles (UFP) from aircrafts. To date, little attention has been given to occupational exposures to aircraft-related UFP, although aircraft engines have high emissions of ultrafine particles, which are orders of magnitude higher than residential exposure. UFP could possibly contribute to the development of cancer, heart disease, mental illness, and respiratory symptoms. In addition to particulate matter, apron workers are exposed to other polluting substances associated with vehicles, aircraft exhaust or direct fuel emissions. Methods We performed…

World Health Organization guidelines for cancer pain: a reappraisal

2005

Pain is a prevalent symptom experienced by at least 30% ofpatients undergoing an oncological treatment for metastaticdisease and by more than 70% of advanced cancer patients[1]. In 1986 the World Health Organization [2] published a setof guidelines for cancer pain management based on the three-step analgesic ladder [2]. The main aim of WHO guidelienswas to legitimize the prescribing of strong opioids, arisingfrom evidence of poor management of cancer pain, due toreluctance of health care professionals, institutions, and gov-ernment to use opioids because of fears of addition, toleranceand illegal abuse.Its application is reported to achieve satisfactory pain reliefin up to 90% of patients w…

2017

Abstract Background Neurofeedback (NF) in children with ADHD has been investigated in a series of studies over the last years. Previous studies did not unanimously support NF as a treatment in ADHD. Most studies did not control for unspecific treatment effects and did not demonstrate that self-regulation took place. The present study examined the efficacy of NF in comparison to electromyographic feedback (EMG) to control for unspecific effects of the treatment, and assessed self-regulation of slow cortical potentials (SCP). Methods A total of 150 children aged 7 - 9 years diagnosed with ADHD (82% male; 43% medicated) were randomized to 25 sessions of feedback of slow cortical potentials (NF…
