Health Literacy among Health and Social Care University Students

Health literacy has been defined by the World Health Organization as the cognitive and social skills which determine the motivation and ability of individuals to gain access to, understand and use information in ways which promote and maintain good health. Its importance in reducing inequalities makes health literacy a thematic area that should be addressed in the training of professionals in the fields of healthcare, Social Work and Education. The objective of this study was to define the health literacy levels of students from the Universities of Girona and Barcelona (Spain) and the Regional Institute of Social Work in Perpignan (France). A cross-sectional study was conducted among students of Nursing, Social Work, Primary Education and Special Education in the 2017-2018 academic year. Sociodemographic and academic variables were considered and the HLS-EU-Q16 questionnaire was used to study health literacy levels. In total, 219 students with an average age of 24.9 participated. Of these, 64.4% were studying Social Work, 23.7% Nursing, 5.9% Primary Education, and 5.9% Special Education. Of the total sample, 36.5% were classified as sufficient in health literacy. The total average score of the health literacy index was 11.1; 13.2 among Nursing students; 10.5 among Social Work students; 10.1 among Primary Education students, and 10.1 among Special Education students (p < 0.001). Nursing students obtained the best results and healthcare was the highest rated subdomain, more than disease prevention and health promotion

Train-to-Ground communications of a Train Control and Monitoring Systems: A simulation platform modelling approach

Under the SAFE4RAIL project, we are developing a simulation platform based on a discrete-events network simulator."br" This platform models the Train-to-Ground (T2G) link in the framework of a system-level simulation of"br" Train Control Management System (TCMS). The modelled T2G link is based on existing wireless technologies,"br" e.g. Wi-Fi and LTE. Different T2G scenarios are defined in order to evaluate the performances of the Mobile"br" Communication Gateway (managing train communications) and Quality of Services (QoS) offered to TCMS applications"br" in the context of various environments (regular train lines, train stations, shunting zones, etc.) while"br" varying the number of communicating trains, train’s speed, radio channel characteristics (delay spread, channel"br" attenuation, etc.). This paper focusses on the design and validation of the TCMS transmission over Wi-Fi/LTE via"br" an approach based on simulation. This simulation platform aims to be also used to test actual TCMS equipment’s,"br" i.e. Mobile Communication Gateway and Ground Communication Gateway, connected to it through Hardware-"br" In-the-Loop facilities of the chosen discrete-events network simulator.

Structure-Activity relationship of novel second-generation synthetic cathinones: Mechanism of action, locomotion, reward, and immediate-early genes

Several new synthetic cathinones, which mimic the effect of classical psychostimulants such as cocaine or MDMA, have appeared in the global illicit drug market in the last decades. In fact, the illicit drug market is continually evolving by constantly adding small modifications to the common chemical structure of synthetic cathinones. Thus, the aim of this study was to investigate the in vitro and in vivo structure-activity relationship of six novel synthetic cathinones currently popular as recreational drugs, Pentedrone, Pentylone, N-ethyl-pentedrone (NEPD), N-ethyl-pentylone (NEP), 4-methyl-pentedrone (4-MPD) and 4-methyl-ethylaminopentedrone (4-MeAP), which structurally differ in the absence or presence of different aromatic substituents and in their amino terminal group. Human embryonic kidney cells (HEK293) expressing the human isoforms of SERT and DAT were used for the uptake inhibition and release assays. Moreover, Swiss-CD-1 mice were used to investigate their psychostimulant effect, rewarding properties (3, 10 and 30 mg/kg, i.p.) and the induction of immediate-early genes (IEGs) such as arc and c-fos in dorsal (DS) and ventral striatum (VS) as well as bdnf in medial prefrontal cortex (mPFC). Our results demonstrated that all tested synthetic cathinones are potent dopamine (DA) uptake inhibitors, especially the N-ethyl analogues, while the ring-substituted cathinones tested showed higher potency as SERT inhibitors than their no ring-substituted analogues. Moreover, unlike NEP, all tested compounds showed 'hybrid' properties, acting as DAT blockers but SERT substrates. Regarding the locomotion, NEP and NEPD were more efficacious (10 mg/kg) than their N-methyl analogues, which correlates with their higher potency inhibiting DAT and an overexpression of arc levels in DS and VS. Furthermore, all compounds tested induced an increase in c-fos expression in DS, except for 4-MPD, the least effective compound at inducing hyperlocomotion. Moreover, NEP induced an up-regulation of bdnf in mPFC that correlates whit its 5-HTergic properties. Finally, the present study demonstrated for the first time that pentylone, NEP, 4-MPD and 4-MeAP induce reward in mice. Altogether, this study provides valuable information about the mechanism of action, psychostimulant and rewarding properties as well as changes in the expression of IEGs related to addiction induced by novel second-generation synthetic cathinones

TRIM33 switches off Ifnb1 gene transcription during the late phase of macrophage activation

Despite its importance during viral or bacterial infections, transcriptional regulation of the interferon-β gene (Ifnb1) in activated macrophages is only partially understood. Here we report that TRIM33 deficiency results in high, sustained expression of Ifnb1 at late stages of toll-like receptor-mediated activation in macrophages but not in fibroblasts. In macrophages, TRIM33 is recruited by PU.1 to a conserved region, the Ifnb1 Control Element (ICE), located 15 kb upstream of the Ifnb1 transcription start site. ICE constitutively interacts with Ifnb1 through a TRIM33-independent chromatin loop. At late phases of lipopolysaccharide activation of macrophages, TRIM33 is bound to ICE, regulates Ifnb1 enhanceosome loading, controls Ifnb1 chromatin structure and represses Ifnb1 gene transcription by preventing recruitment of CBP/p300. These results characterize a previously unknown mechanism of macrophage-specific regulation of Ifnb1 transcription whereby TRIM33 is critical for Ifnb1 gene transcription shutdown

Cognitive disorders in patients with chronic kidney disease: Approaches to prevention and treatment

Background: Cognitive impairment is common in patients with chronic kidney disease (CKD), and early intervention may prevent the progression of this condition. Methods: Here, we review interventions for the complications of CKD (anemia, secondary hyperparathyroidism, metabolic acidosis, harmful effects of dialysis, the accumulation of uremic toxins) and for prevention of vascular events, interventions that may potentially be protective against cognitive impairment. Furthermore, we discuss nonpharmacological and pharmacological methods to prevent cognitive impairment and/or minimize the latter's impact on CKD patients' daily lives. Results: A particular attention on kidney function assessment is suggested during work-up for cognitive impairment. Different approaches are promising to reduce cognitive burden in patients with CKD but the availabe dedicated data are scarce. Conclusions: There is a need for studies assessing the effect of interventions on the cognitive function of patients with CKD

Prospective individual patient data meta-analysis of two randomized trials on convalescent plasma for COVID-19 outpatients

Data on convalescent plasma (CP) treatment in COVID-19 outpatients are scarce. We aimed to assess whether CP administered during the first week of symptoms reduced the disease progression or risk of hospitalization of outpatients. Two multicenter, double-blind randomized trials (NCT04621123, NCT04589949) were merged with data pooling starting when = 50 years and symptomatic for <= 7days were included. The intervention consisted of 200-300mL of CP with a predefined minimum level of antibodies. Primary endpoints were a 5-point disease severity scale and a composite of hospitalization or death by 28 days. Amongst the 797 patients included, 390 received CP and 392 placebo; they had a median age of 58 years, 1 comorbidity, 5 days symptoms and 93% had negative IgG antibody-test. Seventy-four patients were hospitalized, 6 required mechanical ventilation and 3 died. The odds ratio (OR) of CP for improved disease severity scale was 0.936 (credible interval (CI) 0.667-1.311); OR for hospitalization or death was 0.919 (CI 0.592-1.416). CP effect on hospital admission or death was largest in patients with <= 5 days of symptoms (OR 0.658, 95%CI 0.394-1.085). CP did not decrease the time to full symptom resolution

A pan-European epidemiological study reveals honey bee colony survival depends on beekeeper education and disease control

Reports of honey bee population decline has spurred many national efforts to understand the extent of the problem and to identify causative or associated factors. However, our collective understanding of the factors has been hampered by a lack of joined up trans-national effort. Moreover, the impacts of beekeeper knowledge and beekeeping management practices have often been overlooked, despite honey bees being a managed pollinator. Here, we established a standardised active monitoring network for 5 798 apiaries over two consecutive years to quantify honey bee colony mortality across 17 European countries. Our data demonstrate that overwinter losses ranged between 2% and 32%, and that high summer losses were likely to follow high winter losses. Multivariate Poisson regression models revealed that hobbyist beekeepers with small apiaries and little experience in beekeeping had double the winter mortality rate when compared to professional beekeepers. Furthermore, honey bees kept by professional beekeepers never showed signs of disease, unlike apiaries from hobbyist beekeepers that had symptoms of bacterial infection and heavy Varroa infestation. Our data highlight beekeeper background and apicultural practices as major drivers of honey bee colony losses. The benefits of conducting trans-national monitoring schemes and improving beekeeper training are discussed
