RESUMO

The first results of the study of high-energy electron neutrino (ν_{e}) and muon neutrino (ν_{µ}) charged-current interactions in the FASERν emulsion-tungsten detector of the FASER experiment at the LHC are presented. A 128.8 kg subset of the FASERν volume was analyzed after exposure to 9.5 fb^{-1} of sqrt[s]=13.6 TeV pp data. Four (eight) ν_{e} (ν_{µ}) interaction candidate events are observed with a statistical significance of 5.2σ (5.7σ). This is the first direct observation of ν_{e} interactions at a particle collider and includes the highest-energy ν_{e} and ν_{µ} ever detected from an artificial source. The interaction cross section per nucleon σ/E_{ν} is measured over an energy range of 560-1740 GeV (520-1760 GeV) for ν_{e} (ν_{µ}) to be (1.2_{-0.7}^{+0.8})×10^{-38} cm^{2} GeV^{-1} [(0.5±0.2)×10^{-38} cm^{2} GeV^{-1}], consistent with standard model predictions. These are the first measurements of neutrino interaction cross sections in those energy ranges.

RESUMO

BACKGROUND: Fatigue is a highly prevalent condition among people affected by chronic disease, with consequent poor health-related quality of life and lower survival rates. Fatigue is one of the most common and debilitating symptoms also experienced by hemodialysis (HD) patients after HD sessions, and given the non-specific manifestations and its invisible nature, it is under-recognized and under-treated by healthcare professionals. The complexity of fatigue's pathogenesis and the lack of measurement tools make the development of nursing interventions and practices specifically targeted at its recognition and therapy difficult. We aimed to investigate the prevalence and severity of fatigue, identify predictor variables in HD patients, and promote healthcare professionals' awareness and recognition of fatigue. MATERIALS AND METHODS: A single-center, cross-sectional study was conducted among 140 patients treated at the HD unit between August 2019 and March 2020 at the Nephrology, Dialysis, and Transplantation Unit of Padova University Hospital. We assessed patient's fatigue by Chalder's Fatigue Questionnaire, pain by Numeric Rating Scale and activities of daily living by Barthel Index. Demographic and clinical characteristics were taken from medical records. RESULTS: The findings of this study indicate that age, dialysis vintage, inter-dialysis weight gain, and ultra-filtration rate are proportionally related to reported levels of fatigue. Hemoglobin, iron, ferritin, and number of sleep hours before HD session present a significant inverse correlation to fatigue. CONCLUSION: The complexity of fatigue's pathogenesis makes a better understanding of this phenomenon difficult, nevertheless, healthcare professionals should develop interventions and practices targeted at its identification and management.

RESUMO

BACKGROUND: Sorafenib is currently the only approved systemic treatment for hepatocellular carcinoma. AIM: to evaluate safety and effectiveness of sorafenib in the field of practice. METHODS: We report a single-centre experience on 116 advanced hepatocellular carcinoma patients treated with sorafenib between February 2008 and March 2011. Every 4 weeks, adverse events were graded using Common Toxicity Criteria version 3.0, and every 3 months tumour response was assessed according to modified Response Evaluation Criteria in Solid Tumours for hepatocellular carcinoma. RESULTS: Cirrhosis was present in 95.7% of patients (83.6% Child-Pugh A class), hepatitis C was the main etiological factor. Median therapy duration was 3 months and median daily dose was 642 mg. Median time-to-radiological progression in the per-protocol population was 12 months and median overall survival in the intention-to-treat population was 13 months. 91.4% of patients experienced mild adverse events (grade 1 or 2), the most frequent were gastrointestinal and dermatological. Jaundice and bleeding were the main causes of definitive drug discontinuation. 3-month overall disease control rate was 70.6%: stable disease in 37.2%, partial response in 30.8%, and complete response in 2.6% patients. The 3-month radiological response correlated with overall survival. CONCLUSIONS: In daily clinical practice, sorafenib confirmed its safety and efficacy in hepatocellular carcinoma patients.
