High energy interactions on nuclei

Multihadron production and coherent or semicoherent reactions on nuclei allow information about such intriguing topics as space-time development of particle production and interactions of resonances with nucleons. Some of the latest results are here summarized, with particular emphasis on the coherent and semicoherent channels, in connection with the criticisms and suggestions recently developed regarding the so called sigma /sub 2/ cross-section (for the interactions of resonances with nucleons), as it is obtained from the A dependence of diffractive production on nuclei.

Caring for Critically Ill Patients : Clinicians’ Empathy Promotes Job Satisfaction and Does Not Predict Moral Distress

Background: Several studies have highlighted the benefits of empathy in healthcare settings. A correlation between clinicians' empathy and patients' adherence and satisfaction, as well as the ability for the clinician to accurately assess family members' needs, has been found. However, empathy is often seen by clinicians as a risk factor for their wellbeing. This study aims to assess whether the level of empathy of clinicians working in critical care settings may expose them to moral distress, poor job satisfaction, and intention to quit their job. Methods: Italian clinicians who attended the 2016 "Smart Meeting Anesthesia Resuscitation in Intensive Care" completed the Empathy Quotient questionnaire, the Moral Distress Scale-Revised, and two questions assessing job satisfaction and intention to quit the job. Multiple linear and logistic regressions were performed to determine if clinicians' empathy influences moral distress, job satisfaction, and intention to quit. Age, gender, and profession were used as control variables. Results: Out of 927 questionnaires distributed, 216 were returned (23% response rate) and 210 were used in the analyses. Respondents were 56% physicians, 24% nurses, and 20% residents. Over half of the clinicians (58%) were female. Empathy resulted the only significant predictor of job satisfaction (\u3b2 = 0.193; p < 0.05). None of the variables included in the model predicted moral distress. Conclusion: Empathy determined neither moral distress nor intention to quit. Findings suggest that empathy is not a risk factor for critical care clinicians in developing moral distress and the intention to quit their job. On the contrary, empathy was found to enhance clinicians' job satisfaction

Am I carrier? The patient's lived experience of thrombophilia genetic screening and its output

How do patients with thrombophilia experience a physician's request to undergo a genetic test? How do they experience the test outcome? To answer these questions, we conducted an interpretative phenomenological analysis study, based on 10 in-depth interviews with patients who underwent genetic testing for thrombophilia in Italy, half with positive and half with negative results. The experience of undergoing genetic screening for thrombophilia plays an important role in reconfiguring patients' signification of their illness experience. A positive outcome becomes a cue to reorganize in a more adaptive way the illness meaning at the cognitive and emotive levels, whereas a negative outcome appears more distressing and confusing. As a clinical implication of the study, clinicians should consider communicating carefully with the patients regardless from the positive/negative test results and they should explore the patient's specific reaction and understanding of test result

Evaluation of sixty-eight cases of fracture stabilisation by external hybrid fixation and a proposal for hybrid construct classification

Background: Hybrid external fixation (HEF) is an emerging technique for fracture stabilization in veterinary orthopedics, but its use has been reported in few papers in the veterinary literature. The linear and circular elements that form hybrid fixators can be connected in a very high number of combinations, and for this reason just referring to HEF without any classification is often misleading about the actual frame structure. The aim of this study was to retrospectively evaluate fracture stabilization by HEF in 58 client-owned dogs and 8 cats, and to extend the already existing classification for hybrid constructs to include all frame configurations used in this study and potentially applicable in clinical settings. Animal signalment, fracture classification, surgical procedure and frame configuration were recorded. Complications, radiographic, functional and cosmetic results were evaluated at the time of fixator removal.Results: Sixty-eight fractures in 58 dogs and eight cats were evaluated. Two dogs had bilateral fractures. Fifty-one percent were radio-ulna, 34% tibial, 9% humeral, 3% femoral and 3% scapular fractures. One ring combined with one or two linear elements was the most widely employed configuration in this case series. Radiographic results at the time of frame removal were excellent in 59% of the cases, good in 38% and fair in 3%, while functional and cosmetic results were excellent in 69% of the cases, good in 27% and fair in 4%.Conclusions: HEF is a useful option for fracture treatment in dogs and cats, particularly for peri and juxta-articular fractures. It can be applied with a minimally invasive approach, allows adjustments during the postoperative period and is a versatile system because of the large variety of combinations that can fit with the specific fracture features. The classification used enables to determine the number of linear and circular elements used in the frame

Measuring Moral Distress Among Critical Care Clinicians : Validation and Psychometric Properties of the Italian Moral Distress Scale-Revised

OBJECTIVES: Moral distress is a common experience among critical care professionals, leading to frustration, withdrawal from patient care, and job abandonment. Most of the studies on moral distress have used the Moral Distress Scale or its revised version (Moral Distress Scale-Revised). However, these scales have never been validated through factor analysis. This article aims to explore the factorial structure of the Moral Distress Scale-Revised and develop a valid and reliable scale through factor analysis. DESIGN: Validation study using a survey design. SETTING: Eight medical-surgical ICUs in the north of Italy. SUBJECTS: A total of 184 clinicians (64 physicians, 94 nurses, and 14 residents). INTERVENTIONS: The Moral Distress Scale-Revised was translated into Italian and administered along with a measure of depression (Beck Depression Inventory-Second Edition) to establish convergent validity. Exploratory factor analysis was conducted to explore the Moral Distress Scale-Revised factorial structure. Items with low (less than or equal to 0.350) or multiple saturations were removed. The resulting model was tested through confirmatory factor analysis. MEASUREMENTS AND MAIN RESULTS: The Italian Moral Distress Scale-Revised is composed of 14 items referring to four factors: futile care, poor teamwork, deceptive communication, and ethical misconduct. This model accounts for 59% of the total variance and presents a good fit with the data (root mean square error of approximation = 0.06; comparative fit index = 0.95; Tucker-Lewis index = 0.94; weighted root mean square residual = 0.65). The Italian Moral Distress Scale-Revised evinces good reliability (\u3b1 = 0.81) and moderately correlates with Beck Depression Inventory-Second Edition (r = 0.293; p < 0.001). No significant differences were found in the moral distress total score between physicians and nurses. However, nurses scored higher on futile care than physicians (t = 2.051; p = 0.042), whereas physicians scored higher on deceptive communication than nurses (t = 3.617; p < 0.001). Moral distress was higher for those clinicians considering to give up their position (t = 2.778; p = 0.006). CONCLUSIONS: The Italian Moral Distress Scale-Revised is a valid and reliable instrument to assess moral distress among critical care clinicians and develop tailored interventions addressing its different components. Further research could test the generalizability of its factorial structure in other cultures

Cognitive Neuro-Rehabilitation of HIV-Associated Neurocognitive Disorders : Case Reports of A New Computer-Based Restorative Approach In 3 Hiv-Positive Cart-Treated Patients

At enrolment (T0) three on combination antiretroviral therapy (cART) HIV-positive patients with HIV Associated Neurocognitive Disorders (HAND) were enrolled to undergo a computer-based rehabilitation program (https://dynamicbrain.brainhq.com/) for 12 weeks, under the supervision of a physician. At the end (T1), the patients were tested again with a neuropsychological battery. Patient 1 (current CD4 T-cell count 405/mmc, HIV-RNA < 40UI/ml) had a diagnosis of mild neurocognitive disorders (MND) at T0 and normal evaluation at T1. Patient 2 (current CD4 T-cell count 366/mmc, HIV-RNA < 40UI/ml) had asymptomatic neurocognitive disorders (ANI) at T0 and normal performance at T1. Patient 3 (current CD4 T-cell count 522/mmc, HIV-RNA < 40UI/ml) had MND at T0 and normal performances at T1. Patients\u2019 adherence to the program was 100%. Our pilot experience with a computer-based restorative approach showed good results in term of improvement in neuropsychological performances in treated HIV+ patients. These data suggest the need to explore innovative ways to manage HAND

Cross-cultural adaptation of an innovative approach to learning about difficult conversations in healthcare

Background:\u2003The Program to Enhance Relational and Communication Skills (PERCS) was developed at a large hospital in the United States to enhance clinicians\u2019 preparedness to engage in difficult conversations. Aim:\u2003To describe the implementation of PERCS in an Italian hospital and assess the program's efficacy. Methods:\u2003The Italian PERCS program featured 4-h experiential workshops enrolling 10\u201315 interdisciplinary participants. The workshops were organized around the enactment and debriefing of realistic case scenarios portrayed by actors and volunteer clinicians. Before and after the workshop, participants rated their perceived preparation, communication and relational skills, confidence, and anxiety on 5-point Likert scales. Open-ended questions explored their reflections on the learning. T-tests and content analysis were used to analyze the quantitative and qualitative data, respectively. Results:\u2003146 clinicians attended 13 workshops. Participants reported better preparation, confidence, and communication skills (p\u2009<\u20090.001) after the workshops. The program had a different impact depending on the discipline. Participants valued the emphasis on group feedback, experiential and interdisciplinary learning, and the patient's perspective, and acquired: new communication skills, self-reflective attitude, reframed perspective, and interdisciplinary teamwork. Conclusion:\u2003PERCS proved culturally adaptable to the Italian context and effective in improving participants\u2019 sense of preparation, communication skills, and confidence

Perspectives and Emotional Experiences of Patients With Chronic Myeloid Leukemia During ENESTPath Clinical Trial and Treatment-Free Remission: Rationale and Protocol of the Italian Substudy

Achievement of deep molecular response following treatment with a tyrosine kinase inhibitor (TKI) allows for treatment-free remission (TFR) in many patients with chronic myeloid leukemia (CML). Successful TFR is defined as the achievement of a sustained molecular response after cessation of ongoing TKI therapy. The phase 3 ENESTPath study was designed to determine the required optimal duration of consolidation treatment with the second-generation TKI, nilotinib 300 mg twice-daily, to remain in successful TFR without relapse after entering TFR for 12 months. The purpose of this Italian ‘patient’s voice CML’ substudy was to evaluate patients’ psycho-emotional characteristics and quality of life through their experiences of stopping treatment with nilotinib and entering TFR. The purpose of the present contribution is to early present the study protocol of an ongoing study to the scientific community, in order to describe the study rationale and to extensively present the study methodology. Patients aged ≥18 years with a confirmed diagnosis of Philadelphia chromosome positive BCR-ABL1+ CML in chronic phase and treated with front-line imatinib for a minimum of 24 months from the enrollment were eligible. Patients consenting to participate the substudy will have quality of life questionnaires and in-depth qualitative interviews conducted. The substudy will include both qualitative and quantitative design aspects to evaluate the psychological outcomes as assessed via patients’ emotional experience during and after stopping nilotinib therapy. Randomization is hypothesized to be a timepoint of higher psychological alert or distress when compared to consolidation and additionally any improvement in health-related quality of life (HRQoL) due to nilotinib treatment is expected across the timepoints (from consolidation, to randomization, and TFR). An association is also expected between dysfunctional coping strategies, such as detachments and certain personality traits, and psychological distress and HRQoL impairments. Better HRQoL outcomes are expected in TFR compared to the end of consolidation. This substudy is designed for in-depth assessment of all potential psycho-emotional variables and aims to determine the need for personalized patient care and counselling, and also guide clinicians to consider the psychological well-being of patients who are considering treatment termination.

Search for charginos in e+e- interactions at sqrt(s) = 189 GeV

An update of the searches for charginos and gravitinos is presented, based on a data sample corresponding to the 158 pb^{-1} recorded by the DELPHI detector in 1998, at a centre-of-mass energy of 189 GeV. No evidence for a signal was found. The lower mass limits are 4-5 GeV/c^2 higher than those obtained at a centre-of-mass energy of 183 GeV. The (\mu,M_2) MSSM domain excluded by combining the chargino searches with neutralino searches at the Z resonance implies a limit on the mass of the lightest neutralino which, for a heavy sneutrino, is constrained to be above 31.0 GeV/c^2 for tan(beta) \geq 1.Comment: 22 pages, 8 figure
