Learning impact of education during pulmonary rehabilitation program. An observational short-term cohort study

Background: Among the several components integrating a pulmonary rehabilitation (PR) course, education may contribute to the individual\u2019s recognition of symptoms and worsening of the disease. However, the specific gain of education is far to be clearly documented to the health care providers. Aim of our preliminary study was to assess the learning impact of educational sessions (ES) in Chronic Obstructive Pulmonary Disease (COPD) patients referred to standard PR.Methods: Six ES on 3 areas (Symptoms-Therapies, Aids, Mood) were applied during PR at our clinic. The learning effect was prospectively evaluated by a specific questionnaire (ESQ) in 285 COPD patients (age 69\ub18 years, FEV1 53\ub114 % pred), then grouped into those who have completed ES (Completers group, n=226) or who did not (mean 2\ub11 ES) (Control group, n=59). Total and partial ESQ scores, and PR outcomes (6-minute walking test-6MWD, effort-dyspnoea at Medical Research Council scale-MRC, and health-related quality of life scale-SGRQ) were assessed in a pre (T0) to post (Tend) design.Results: Similar improvement in PR outcomes was recorded in both groups at Tend, whereas ESQ total and partial scores significantly increased in Completers only (p<0.001). ESQ-Aids score improved to a greater extent in Completers than in Control (+0.60\ub11.03 vs +0.27\ub11.27 point respectively, p=0.036). A higher proportion of Completers improved above the median change of both ESQ total and aids scores (p<0.05).Conclusion: Attending educational sessions produces a specific short-term learning effect during rehabilitation of COPD patients

Reduction of Multipacting in an Accelerator Cavity

The choice of a suitable geometry in designing a radio-frequency cavity for e+ e- storage ring allows the reduction of multipacting (MP) discharges. We have studied the behaviour of resonant electron discharges in the RF cavity of the Adone storage ring in Frascati, that shows a broad MP barrier in the 35 to 70 kV range of the accelerating voltage. It can be explained by one point MP on the end-plates of the resonator. Our computer simulations of the trajectories of electrons in the RF fields of the cavity clearly show multipacting trajectories in that region of the cavity at about that field level. On the base of our experimental measurements and simulations, the design of a new RF cavity, multipactor free in the end-plates region, is presented

The Politics of Exhaustion and the Externalization of British Border Control. An Articulation of a Strategy Designed to Deter, Control and Exclude

In response to contemporary forms of human mobility, there has been a continued hardening of borders seeking to deter, control and exclude certain groups of people from entering nation states in Europe, North America and Australasia. Within this context, a disconcerting evolution of new and increasingly sophisticated forms of border control measures have emerged, which often play out within bilateral arrangements of “externalised” or “offshore” border controls. Drawing on extensive first‐hand field research among displaced people in Calais, Paris and Brussels in 2016–2019, this paper argues that the externalization of the British border to France is contingent upon a harmful strategy, which can be understood as the “politics of exhaustion.” This is a raft of (micro) practices and methods strategically aimed to deter, control and exclude certain groups of people on the move who have been profiled as “undesirable,” with a detrimental (un)intended impact on human lives

Learning impact of education during Pulmonary Rehabilitation program. An observational short-term cohort study

Background. Among the several components constituting a pulmonary rehabilitation (PR) course, education may contribute to an individual’s recognition of symptoms and worsening of the disease. However, the specific benefits of education is far greater than can be clearly documented to the health care providers. The aim of our preliminary study was to assess the learning impact of educational sessions (ES) in Chronic Obstructive Pulmonary Disease (COPD) patients referred to standard PR. Methods. Six ES on 3 areas (Symptoms-Therapies, Aids, Mood) were applied during PR at our clinic. The learning effect was prospectively evaluated by a specific questionnaire (ESQ) in 285 COPD patients (age 69±8 years, FEV1 53±14 % pred), then grouped into those who have completed ES (Completers group, n=226) or who did not (mean 2±1 ES) (Control group, n=59). Total and partial ESQ scores, and PR outcomes (6-minute walking test- 6MWD, effort-dyspnoea at Medical Research Council scale-MRC, and health-related quality of life scale-SGRQ) were assessed in a pre (T0) to post (Tend) design. Results. Similar improvement in PR outcomes was recorded in both groups at Tend, whereas ESQ total and partial scores significantly increased in ‘Completers’ only (p<0.001). ESQ-Aids score improved to a greater extent in Completers than in Control (+0.60±1.03 vs +0.27±1.27 point respectively, p=0.036). A higher proportion of Completers improved above the median change of both ESQ total and aids scores (p<0.05). Conclusion. Attending educational sessions produces a specific short-term learning effect during rehabilitation of COPD patients

Containment beyond detention: The hotspot system and disrupted migration movements across Europe

This article deals with the ways in which migrants are controlled, contained and selected after landing in Italy and in Greece, drawing attention to strategies of containment aimed at disciplining mobility and showing how they are not narrowed to detention infrastructures. The article starts by tracing a genealogy of the use of the term ‘hotspot’ in policy documents and suggests that the multiplication of hotspots-like spaces is related to a reconceptualisation of the border as a critical site that requires prompt enforcement intervention. The article moves on by investigating the mechanisms of partitioning, identification and preventive illegalisation that are at stake in the hotspots of Lampedusa and Lesbos. Hotspots are not analysed here as sites of detention per se: rather, the essay turns the attention to the channels of forced mobility that are connected to the Hotspot System, focusing in particular on the forced transfers of migrants from the Italian cities of Ventimiglia and Como to the hotspot of Taranto. The article concludes by analysing channels of forced mobility in the light of the fight against ‘secondary movements’ that is at the core of the current European Union’s political agenda, suggesting that further academic research could engage in a genealogy of practices of migration containment

The PLASMONX Project for advanced beam physics experiments

The Project PLASMONX is well progressing into its design phase and has entered as well its second phase of procurements for main components. The project foresees the installation at LNF of a Ti:Sa laser system (peak power > 170 TW), synchronized to the high brightness electron beam produced by the SPARC photo-injector. The advancement of the procurement of such a laser system is reported, as well as the construction plans of a new building at LNF to host a dedicated laboratory for high intensity photon beam experiments (High Intensity Laser Laboratory). Several experiments are foreseen using this complex facility, mainly in the high gradient plasma acceleration field and in the field of mono- chromatic ultra-fast X-ray pulse generation via Thomson back-scattering. Detailed numerical simulations have been carried out to study the generation of tightly focused electron bunches to collide with laser pulses in the Thomson source: results on the emitted spectra of X-rays are presented

First Observation of Self-Amplified Spontaneous Emission in a Free-Electron Laser at 109 nm Wavelength

We present the first observation of Self-Amplified Spontaneous Emission (SASE) in a free-electron laser (FEL) in the Vacuum Ultraviolet regime at 109 nm wavelength (11 eV). The observed free-electron laser gain (approx. 3000) and the radiation characteristics, such as dependency on bunch charge, angular distribution, spectral width and intensity fluctuations all corroborate the existing models for SASE FELs.Comment: 6 pages including 6 figures; e-mail: [email protected]

Summary of Simulation Results for a Muon Cooling Experiment based on the 88 MHz CERN Cooling Channel

We present a summary of simulation results on a muon cooling experiment based on 88MHz cavities. The systems studied are subsections of the cooling channel in the CERN reference scheme for a neutrino factory. We present two different set-ups using 8 and 4 cavities. For each of these channels we have carried out a beam dynamics study based on engineering designs for the cavities and solenoids. The study comprises a scan of input beam parameters, various optics with and without alternating solenoid polarity as well as a cross-check with an independent simulation code
