    Quantitative assessment of diffuse myocardial fibrosis in II-type diabetes mellitus patients using T1 mapping technique: preliminary data

    In diabetic cardiomyopathy (DCM), ventricular remodelling consists in a progressive impairment of myocardial contraction (evolving from diastolic to combined diastolic-systolic dysfunction) occurring regardless of ischemic heart disease, hypertension or other macrovascular complications, which ultimately leads to heart failure. Early stages of DCM are asymptomatic and characterised by initial contractile disfunction and various degree of myocardial fibrosis, that may not be recognised by traditional cardiology tests. Our purpose was to detect myocardial fibrotic infiltration in DM-II patients by using T1-mapping technique with extracellular volume fraction (ECV) measurement

    Measuring knowledge, attitudes and behavior of nurses in medication management. Cross-cultural comparisons in Italy and Malta

    Get PDF
    Medication errors are one of the most common causes of negative events affecting patient safety all over the world.  Scientific literature divides the factors that contribute to the occurrence of harmful events into factors related to the characteristics of the healthcare workers and factors related to the organization of the drug management process. The aim of the study was to examine the knowledge, attitudes and behaviours related to medication errors among Italian and Maltese nurses

    Soliton-like Spin State in the A-like Phase of 3He in Anisotropic Aerogel

    Full text link
    We have found a new stable spin state in the A-like phase of superfluid 3He confined to intrinsically anisotropic aerogel. The state can be formed by radiofrequency excitation applied while cooling through the superfluid transition temperature and its NMR properties are different from the standard A-like phase obtained in the limit of very small excitation. It is possible that this new state is formed by textural domain walls pinned by aerogel.Comment: 9 pages, 3 figures. Submitted to J. of Low Tem. Phys. (QFS2007 Proceedings

    A Sharp Peak of the Zero-Temperature Penetration Depth at Optimal Composition in BaFe2(As1-xPx)2

    In a superconductor, the ratio of the carrier density, nn, to their effective mass, m∗m^*, is a fundamental property directly reflecting the length scale of the superfluid flow, the London penetration depth, λL\lambda_L. In two dimensional systems, this ratio n/m∗n/m^* (∼1/λL2\sim 1/\lambda_L^2) determines the effective Fermi temperature, TFT_F. We report a sharp peak in the xx-dependence of λL\lambda_L at zero temperature in clean samples of BaFe2_2(As1−x_{1-x}Px_x)2_2 at the optimum composition x=0.30x = 0.30, where the superconducting transition temperature TcT_c reaches a maximum of 30\,K. This structure may arise from quantum fluctuations associated with a quantum critical point (QCP). The ratio of Tc/TFT_c/T_F at x=0.30x = 0.30 is enhanced, implying a possible crossover towards the Bose-Einstein condensate limit driven by quantum criticality.Comment: Main text (5 pages, 4 figures) + Supplementary Materials (5 pages, 5 figures).

    Absence of non-linear Meissner effect in YBa2Cu3O6.95

    Full text link
    We present measurements the field and temperature dependence of the penetration depth (lambda) in high purity, untwinned single crystals of YBa2Cu3O6.95 in all three crystallographic directions. The temperature dependence of lambda is linear down to low temperatures, showing that our crystals are extremely clean. Both the magnitude and temperature dependence of the field dependent correction to lambda however, are considerably different from that predicted from the theory of the non-linear Meissner effect for a d-wave superconductor (Yip-Sauls theory). Our results suggest that the Yip-Sauls effect is either absent or is unobservably small in the Meissner state of YBa2Cu3O6.95.Comment: 4 pages, 4 figures (Latex file + Postscipt figures

    Improving sleep quality in cancer patients. a literature review on non-pharmacologic interventions

    Get PDF
    Objective: Disrupted sleep-in cancer patients is due to several factors. Pre-existing sleep disorders, mental status in cancer, or side effects of cancer treatment are all potential predictors of sleep disturbances in this vulnerable population. This review aims to evaluate and synthesise non-pharmaco-logic interventions for improving sleep quality and the associated benefits in cancer patients. Materials and Methods: A literature review was performed according to PRISMA guidelines. PubMed, Google Scholar, MEDLINE, CINAHL, and Embase databases were interrogated, selected the article with cancer, neoplasm, oncology, sleep-wake disorders, sleep disturbance, sleep problem, strategies, treat-ment, and intervention such as keywords. No time and geographic restrictions but paediatrics, children, and interventions unrelated to sleep improvement in cancer were excluded. Results: Overall, twenty-nine articles were included in the review after selection. The included studies analysed different types of cancer, like breast, lung, and prostate cancer and acute leukaemia. Most of the data gathered from the relevant research suggest that nonpharmacologic interventions significantly improved cancer patients’ sleep quality. Conclusions: Cancer survival rates are increasing; researchers and healthcare professionals should aim not just at survival but also to allow cancer patients just comfortably to live, considering the best quality of life possible. Nurses have a crucial role in the care of this patient population. Nursing implies an intimate relationship with patients and educating the patient to improve their mental and physical condition through non-pharmacological approaches, which should be considered a specific competence
