Soddisfazione lavorativa, burnout e stress del personale infermieristico: indagine in due ospedali di Roma

Il termine burnout, introdotto da Freudenberger nel1974, configura una condizione di stress lavorativo ri-scontrabile con maggiore frequenza tra i soggetti impe-gnati in attivita assistenziali: si tratta quindi di una pato-logia professionale particolarmente rilevante per l’areasocio-sanitaria (1, 2). Christina Maslach ha definito il bur-nout come “una sindrome di esaurimento emotivo, deper-sonalizzazione e ridotta realizzazione personale” e ha da-to un importante contributo alla ricerca su tale problema-tica grazie alla elaborazione di uno specifico strumento ditipo psicodiagnostico, il Maslach Burnout Inventory(MBI), standardizzato per l’analisi dei tre aspetti citati (3,5). In particolare, lo stato di “esaurimento emotivo” (EE)si caratterizza per la mancanza dell’energia necessaria adaffrontare la realta quotidiana, con sentimenti di apatia edistacco emotivo nei confronti del lavoro. Il soggetto sisente svuotato, sfinito, le sue risorse emozionali sono ap-punto “esaurite”. Con il termine “depersonalizzazione”(DP) Maslach ha indicato un atteggiamento di ostilita, checoinvolge primariamente la relazione professionale d’aiu-to, vissuta con fastidio, freddezza, cinismo. Di conse-guenza, l’operatore tenta di sottrarsi al coinvolgimento, li-mitando la quantita e qualita dei propri interventi profes-sionali, al punto da rispondere evasivamente alle richiested’aiuto, e sottovalutare, o negare, i problemi del paziente.L’ambito della “ridotta realizzazione professionale” (PA)infine si riferisce ad un sentimento di fallimento profes-sionale, per la percezione della propria inadeguatezza allavoro, sottesa dalla consapevolezza del disinteresse edell’intolleranza verso la sofferenza degli altri, con il con-seguente senso di colpa per le modalita impersonali e di-sumanizzate che hanno ormai sostituito l’efficacia e lacompetenza nel trattare con i pazienti. Alla situazione psi-cologica e relazionale sopra descritta si associano gene-ralmente sintomi fisici, sotto forma di vago malessere,astenia, cefalea, disturbi del sonno (insonnia, o iperson-nia), algie diffuse, turbe dispeptiche (6). Nel complesso, la sindrome di burnout deriva da unosquilibrio tra le richieste professionali e la capacita indivi-duale di affrontarle. Tale stato esprime una sollecitazioneemozionale di frustrazione e demoralizzazione, con difeseinadeguate e comportamenti maladattativi. Per il burnout e
Mechanism underlying bradycardia and long QT 2 related arrhythmias: Interplay between Ca2+ overload and electrical dysfunction

In numerous pathologies, spontaneous Ca2+ release (SCR) emanating from the sarcoplasmic reticulum and occurring during the action potential (AP) plateau can drive voltage instability that initiates arrhythmias, but the direct interplay between SCRs and arrhythmogeneis has not been fully understood in bradycardia and in long QT type 2 (LQT2) models. Simultaneous optical measurement of intracellular Ca2+ transient (CaiT) and AP were performed in Langendorff-perfused rabbit hearts following AV node ablation. Bradycardia and/or LQT2 was/were induced and the spatial heterogeneity of intracellular Ca2+ handling and its link to voltage dispersion were investigated. Upon switching from 120 to 50 beats/min, AP duration (APD) increased gradually with increasing occurrence of SCRs during the AP plateau (p<0.01, n=7). SCR was a) regionally heterogeneous, b) spatially correlated with APD prolongation, c) associated with enhanced dispersion of repolarization (DOR), d) reversed by pacing at 120 beats/min and e) suppressed with K201 (1µM) or flecainide (5µM), inhibitors of cardiac ryanodine receptors (RyR2) which reduced APD (p<0.01, n=5) and DOR (p<0.02, n=5). Western blots of Ca2+ channels/transporters revealed intrinsic spatial distributions of Cav1. 2α and NCX (but not RyR2, and SERCA2a) that correlate with the distribution of SCR and underlie the molecular mechanism responsible for SCRs. In LQT2, lability of Cai, voltage, and ECG signals increased during paced rhythm, before the appearance of early afterdepolarizations (EADs). When EADs appeared, Cai occasionally rose before voltage upstrokes at the origins of propagating EADs. Localized, areas of SCRs appeared in LQT2 and corresponded to areas of prolonged CaiT and APD. Triggered activity appeared after 3-5 min of LQT2 and emanated only at sites with steep membrane potential (Vm) gradients (ΔVm gradient percentile: 94.9 ± 3.2%, n=6). Pre- or post-treatment with K201 suppressed SCRs and decreased DOR, ΔVm and ΔCai. The reduction of ΔVm suppressed triggered activity (n=8/9 hearts). The results show that bradycardia and LQT2 elicit spatially discordant SCR, which is tightly correlated with AP instability. The SCR mediated-enhancement of repolarization gradients and AP prolongation can promote arrhythmogenesis. These findings underscore the importance of a detailed understanding of Ca2+-dependent arrhythmogenic mechanisms for the development of rational treatment strategies.
Effect of transcutaneous electrical nerve stimulation with stretching and exercises in restless leg syndrome among pregnant women

Background: Restless legs syndrome also known as Willis-Ekbom disease is a sensor motor disorder composed of an urge to move with or without associated discomfort that occurs with inactivity and improves with movement. The symptoms occur in leg muscles like calves and thighs. The feet and arms also affected and it causes the functional disability in pregnant women. Sleep disorder is typically the biggest complication of this condition. Unpleasant sensations are deep in the legs. Sensations appear during periods of rest or inactivity particularly in the evening and at night and relived by movement. Prevalence of RLS among pregnant women ranged from 10 to 34%. Aim: The aim of the study is to prove the effect of Transcutaneous Electrical Nerve Stimulation (TENS) with Stretching and Exercises in restless leg syndrome among pregnant women. Objectives: To determine and prove the effectiveness of TENS with stretching to relive pain and improve the functional ability in restless leg syndrome among pregnant women. Materials and Methods: A Quasi-experimental study was conducted on 30 subjects using convenient sampling technique based on inclusion and exclusion criteria. Subjects were allotted into 2 groups i.e., Group A with 15 subjects and Group B with 15 subjects using odd even method of sampling. Experimental group will be treated with TENS and Stretching. Control group will be treated with exercises and massage. Result: Statistical Analysis of Post test for pain and functional performance revealed that patients who received Transcutaneous Electrical Nerve Stimulation (TENS) with Stretching in Group A showed marked improvement compared to patients who received Massage and Exercises in Group B. Conclusion: From the result of the study it concluded that Transcutaneous Electrical Nerve Stimulation (TENS) with Stretching is more effective than massage and exercises in subjects with restless leg syndrome among pregnant women.
Analytical Study of the Organisational Culture- Related Practices in Colleges of Education in Western and Central Regions of Ghana

This study was undertaken to ascertain the organisational culture related practices in Colleges of Education in the Central and Western Regions of Ghana. The conduct of the research was guided by two research questions. The main research instrument used was a questionnaire. Both open-ended and close-ended questions were used. The statistical tools used for the analysis were Frequency, Percentage distributions, Mean and Standard deviations and ANOVA.The study revealed that in spite of the elevation of the Colleges of Education to the tertiary level, most of the practices of the colleges are still based on second cycle organisational culture. The elevation of the Colleges of Education to the tertiary status has imposed challenges on discipline as teacher trainees perceive the rules and regulations of the Colleges as being too strict. Recommendations made include: Measures should be put in place by College authorities to create democratic, open and transparent administration to ensure that both students and tutors operate without fear of being maligned or discriminated against in the performance of their duties. College principals are enjoined to put in place pragmatic measures to facilitate governance of the colleges as tertiary institutions and to ensure that second cycle cultural practices are eschewed.
Time trends in adolescent mental well-being in Czechia between 2002 and 2018: Gender, age and socio-economic differences

Background: Recent literature points to a decline over time in adolescent mental well-being but results are inconsistent and rely mainly on data from Western societies. This study investigates time trends in adolescent mental well-being (psychological and somatic complaints, life satisfaction) among Czech adolescents and explores whether these time trends are moderated by gender, age and socio-economic status. Methods: Nationally representative data from 29,378 Czech adolescents (50.8% girls, M age = 13.43; SD age = 1.65) across five Health Behaviour in School-aged Children (HBSC) surveys (2002, 2006, 2010, 2014, and 2018) were included in the analyses. Hierarchical regression models estimated national trends in adolescent mental well-being. We also tested whether these trends vary between girls and boys, adolescents of different age and from different socio-economic backgrounds. Results: Across the quadrennial surveys from 2002 to 2018, an increase in the psychological complaints was observed. Life satisfaction decreased over time up to 2014 only, whereas somatic symptoms increased until 2010, followed by a decline in 2014 and 2018. Girls, older adolescents and those from low family affluence reported poorer mental well-being outcomes. Gender gap increased over time for psychological complaints and life satisfaction. Socio-economic inequalities gap in adolescent mental well-being remained stable over the investigated timeframe. Conclusions: Our findings do not provide evidence for substantial temporal changes in mental well-being among adolescents in Czechia. Yet, only the increase in psychological complaints has been consistent which is an indicator of a decline over time in adolescent mental well-being. Furthermore, the gender gap in reporting psychological complaints and life satisfaction increased over time, whereas the age and socio-economic differences remained relatively stable. This calls for the attention of public health professionals and policy makers from Czechia.

Engineering of human brain organoids with a functional vascular-like system

Here, we engineered human embryonic stem cells (hESCs) to ectopically express human ETS variant 2 (ETV2) to create in vitro vasculature in cortical organoids (hCOs), namely vhCOs (vascularized hCOs). ETV2-expressing cells in hCOs contributed to forming a complex vascular-like network in hCOs. This protocol describes hESC maintenance, the generation of inducible ETV2 expressing hESCs, and the generation of cortical organoid with functional vascular-like network.
Advanced Modeling of the Performance of Structures Supported on Triple Friction Pendulum Bearings

Seismic isolators, and more specifically, triple friction pendulum (TFP) bearings are ideal earthquake protection technologies for use in performance-based design because they can be designed to achieve multiple performance objectives corresponding to different levels of ground shaking. TFP bearings can limit structure displacement during a design basis (or maximum considered) earthquake while the still effectively isolating the structure under the service level earthquake, reducing seismic demands on the structure and its non-structural components. Furthermore, TFP bearings allow for a gradual transfer of force to the superstructure at ultimate displacement. This dissertation presents an advanced bidirectional model for the TFP bearing that is based on the kinematic and compatibility relationships of the components of the bearing. To validate the model, experimental characterization tests were conducted on the shake table at the University of California, Berkeley. Two distinct types of experiments were conducted: (a) displacement-controlled tests in which the bearings were cycled through specified orbits and (b) unrestrained tests in which the table replicated ground motions recorded during earthquakes. The bidirectional displacement-controlled tests, which are the first of their kind, generated new knowledge to aid in the development and validation of TFP numerical models. The experimental results provided valuable insight into TFP bearing response and showed that the developed bidirectional model accurately captured the observed behavior of the TFP bearing. The advanced model, which includes translational and rotational degrees of freedom in both horizontal directions, tracks all component displacements as well as the change in bearing height during lateral displacements. The model is general so that no a priori conditions regarding bearing properties are required for the validity of the model. These properties make the advanced TFP model a valuable tool to explore the use TFP technology in novel applications. To further the use of seismic isolation in more standard applications, simplified methods are needed for design. This dissertation investigates the use of generalized modal response spectrum methods to approximate global responses of isolated buildings without the need for costly non-linear numerical simulations. The advanced nonlinear TFP model is used for evaluation of the simplified methods. Advanced isolation models are important and necessary for understanding the complex nonlinear dynamic behavior exhibited by seismically isolated structures, and to have confidence that performance goals are achieved under a wide variety of seismic hazards. Such models can, as shown in this dissertation, also be used to assess and improve simplified analysis methods suitable for use in routine design.

U.S. Geographic Analysis of the Cost of Hydrogen from Electrolysis

This report summarizes U.S. geographic analysis of the cost of hydrogen from electrolysis. Wind-based water electrolysis represents a viable path to renewably-produced hydrogen production. It might be used for hydrogen-based transportation fuels, energy storage to augment electricity grid services, or as a supplement for other industrial hydrogen uses. This analysis focuses on the levelized production, costs of producing green hydrogen, rather than market prices which would require more extensive knowledge of an hourly or daily hydrogen market. However, the costs of hydrogen presented here do include a small profit from an internal rate of return on the system. The cost of renewable wind-based hydrogen production is very sensitive to the cost of the wind electricity. Using differently priced grid electricity to supplement the system had only a small effect on the cost of hydrogen; because wind electricity was always used either directly or indirectly to fully generate the hydrogen. Wind classes 3-6 across the U.S. were examined and the costs of hydrogen ranged from $3.74kg to $5.86/kg. These costs do not quite meet the 2015 DOE targets for central or distributed hydrogen production ($3.10/kg and $3.70/kg, respectively), so more work is needed on reducing the cost of wind electricity andmore » the electrolyzers. If the PTC and ITC are claimed, however, many of the sites will meet both targets. For a subset of distributed refueling stations where there is also inexpensive, open space nearby this could be an alternative to central hydrogen production and distribution. « less

Digital Development in Korea: Building an Information Society

This book explores the role of digital information and communications technology in South Koreas development, starting with and building upon the crucial developments of the 1980s. Its perspective draws on the information society concept and on a conceptual model of strategic restructuring of telecommunications. It also draws on firsthand experience in formulating and implementing policies. The analysis identifies aspects of the Korean experience from which developing countries around the world might benefit. Oh and Larson describe the revolutionary developments of the 1980s including the TDX electronic switching system, a major surge forward in semiconductors, the start of privatization and color television and the thoroughgoing restructuring of Koreas telecommunications sector. They further explore government leadership, the growing private sector and international trade pressures in the diffusion of broadband, mobile communication, and convergence toward a ubiquitous network society. The role of education in these developments is explored in detail, along with both the positive and negative aspects of Koreas vibrant new digital media. The book also looks at Koreas growing international involvement, its role in efforts to build a world information society, and finally, its future place in cyberspace. This book will be of interest to students, scholars and policy makers interested in communications technologies, Asian/Korean Studies and development studies.
Superstreet Benefits and Capacities

This research evaluated operational, safety, and perceived effects of superstreets, called restricted crossing U-turn intersections by FHWA, and developed a useful level of service LOS) estimation program which could be used on North Carolina‘s urban and rural arterial roadway system. The operational analysis involved calibrating and validating VISSIM models of three existing signalized superstreets in North Carolina – two isolated intersections, and one five-intersection superstreet corridor. Results from the three models were compared to results from models of equivalent conventional intersections at various volume levels using travel time as the main measure of effectiveness. The superstreet outperformed the conventional intersection at each location studied, reducing the overall average travel time per vehicle traveling through the intersection. The safety analysis involved three separate methods – naive, comparison-group, and Empirical Bayes. Only unsignalized superstreets were analyzed using the Empirical Bayes method. Three signalized superstreets were also evaluated using the Surrogate Safety Assessment Model (SSAM). The results from the analyses were inconclusive with signalized superstreets. Unsignalized superstreets, however, showed a significant reduction in total, angle and right turn, and left turn collisions in all analyses. Analyses also showed a significant reduction in fatal and injury collisions as well. Resident, commuter, and business perceptions of superstreets were evaluated using survey data. The perceptions were mixed within each of the three groups, with some positive and some negative feelings. A LOS program was developed to provide highway capacity and service volumes for superstreets for use in planning applications. The research outcomes will enable the North Carolina Department of Transportation to have a better understanding of superstreet performance, which can lead to cost saving by reductions in collisions and travel time.
