    Title translation Medicated intravascular catheters. Review of the literature.
    Abstract Central Venous Catheters (CVC) are widely used in the setting of intensive care units, but they are associated with an increased risk of CVC-related infections. To prevent infections originated from CVC, a number of devices have been more recently produced, that are characterized by the presence of antiseptic/antibiotic substances in the matrix of the CVC itself ("impregnated" CVC). In this brief review, more recent studies on the topic are discussed, especially in the light of guidelines from the CDC. Although from these studies many suggestions about the efficacy of impregnated CVC in the prevention of CVC-related infections can be derived, notwithstanding the critical role of preventive measures during CVC procedures must be recognized as the principal factor in reducing CVC infections.

    Title translation Survey of measures for the prevention of infections in bone marrow transplantation centers.
    Abstract This paper reports on the results of a survey conducted on the organization of bone marrow transplant (BMT) centers in Italy, with particular attention to the measures routinely adopted for the prevention of infectious complications in BMT patients. In 1997, a questionnaire containing 53 questions with multiple-answers and 15 with single-answer was sent to the 65 Italian BMT centers. The topics addressed in the questionnaire were the following: general structural organization of the BMT center; personnel organization; type of transplants (autologous, allogenic, both); type of protective environment; hygiene measures and food; management of central venous catheters; microbiological surveillance. Fifty questionnaires out of 65 (77%) were available. The analysis of data indicated that most centers (more than 60%) use complex and multiple measures for the prevention of infections. These are mainly represented by careful personal hygiene of the patient, protective isolation of the patient from other patients and relatives; careful washing of personnels' hands before entering patients room; extensive microbiological surveillance. Furthermore, 52% of BMT centers adopt additional measures, such as filtered air, while 22% of centers, on the contrary, lack any air-conditioning apparatus. Overall, the results of the survey indicate that there is a substantial variability in the adoption and evaluation of the impact of such different measures on the incidence of infectious complications after BMT.

    Title translation The role of measures of personal hygiene in the prevention of infections in autologous bone marrow transplantation. Results of a randomized prospective study.
    Abstract The paper reports on the results of a prospective, randomized trial in which two different regimens of personal hygiene procedures have been compared in 30 patients undergoing autologous bone marrow transplantation. The main aim of the study was to evaluate the incidence of infectious episodes in patients enrolled in the trial arm with the simplified hygiene protocol as compared to the standard one, used in our Unit for patients undergoing allogenic transplant. No significant differences between the two study groups in the incidence of infectious episodes or of positive skin cultures were found. Therefore, we suggest that a simplified hygiene protocol is as effective as the standard one in preventing infectious complications in patients undergoing autologous bone marrow transplantation.

    Abstract A search for the decay K_{S}^{0}→μ^{+}μ^{-} is performed using proton-proton collision data, corresponding to an integrated luminosity of 5.6  fb^{-1} and collected with the LHCb experiment during 2016, 2017, and 2018 at a center-of-mass energy of 13 TeV. The observed signal yield is consistent with zero, yielding an upper limit of B(K_{S}^{0}→μ^{+}μ^{-})<2.2×10^{-10} at 90% C.L.. The limit reduces to B(K_{S}^{0}→μ^{+}μ^{-})<2.1×10^{-10} at 90% C.L. once combined with the result from data taken in 2011 and 2012.

    Abstract The ratio of the B_{s}^{0} and B^{+} fragmentation fractions f_{s} and f_{u} is studied with B_{s}^{0}→J/ψϕ and B^{+}→J/ψK^{+} decays using data collected by the LHCb experiment in proton-proton collisions at 7, 8, and 13 TeV center-of-mass energies. The analysis is performed in bins of B-meson momentum, longitudinal momentum, transverse momentum, pseudorapidity, and rapidity. The fragmentation-fraction ratio f_{s}/f_{u} is observed to depend on the B-meson transverse momentum with a significance of 6.0σ. This dependency is driven by the 13 TeV sample (8.7σ), while the results for the other collision energies are not significant when considered separately. Furthermore, the results show a 4.8σ evidence for an increase of f_{s}/f_{u} as a function of collision energy.

    Abstract Searches are performed for both promptlike and long-lived dark photons, A^{'}, produced in proton-proton collisions at a center-of-mass energy of 13 TeV. These searches look for A^{'}→μ^{+}μ^{-} decays using a data sample corresponding to an integrated luminosity of 5.5  fb^{-1} collected with the LHCb detector. Neither search finds evidence for a signal, and 90% confidence-level exclusion limits are placed on the γ-A^{'} kinetic mixing strength. The promptlike A^{'} search explores the mass region from near the dimuon threshold up to 70 GeV and places the most stringent constraints to date on dark photons with 214<m(A^{'})≲740  MeV and 10.6<m(A^{'})≲30  GeV. The search for long-lived A^{'}→μ^{+}μ^{-} decays places world-leading constraints on low-mass dark photons with lifetimes O(1)  ps.<br />

    Abstract Observations are reported of different sources of CP violation from an amplitude analysis of B^{+}→π^{+}π^{+}π^{-} decays, based on a data sample corresponding to an integrated luminosity of 3  fb^{-1} of pp collisions recorded with the LHCb detector. A large CP asymmetry is observed in the decay amplitude involving the tensor f_{2}(1270) resonance, and in addition significant CP violation is found in the π^{+}π^{-}S wave at low invariant mass. The presence of CP violation related to interference between the π^{+}π^{-}S wave and the P wave B^{+}→ρ(770)^{0}π^{+} amplitude is also established; this causes large local asymmetries but cancels when integrated over the phase space of the decay. The results provide both qualitative and quantitative new insights into CP -violation effects in hadronic B decays.

    Abstract A search for the lepton-flavor violating decays B^{+}→K^{+}μ^{±}e^{∓} is performed using a sample of proton-proton collision data, collected with the LHCb experiment at center-of-mass energies of 7 and 8 TeV and corresponding to an integrated luminosity of 3  fb^{-1}. No significant signal is observed, and upper limits on the branching fractions are set as B(B^{+}→K^{+}μ^{-}e^{+})<7.0(9.5)×10^{-9} and B(B^{+}→K^{+}μ^{+}e^{-})<6.4(8.8)×10^{-9} at 90% (95)% confidence level. The results improve the current best limits on these decays by more than one order of magnitude.

    Abstract The first observation of the decays B_{(s)}^{0}→J/ψpp[over ¯] is reported, using proton-proton collision data corresponding to an integrated luminosity of 5.2  fb^{-1}, collected with the LHCb detector. These decays are suppressed due to limited available phase space, as well as due to Okubo-Zweig-Iizuka or Cabibbo suppression. The measured branching fractions are B(B^{0}→J/ψpp[over ¯])=[4.51±0.40(stat)±0.44(syst)]×10^{-7}, B(B_{s}^{0}→J/ψpp[over ¯])=[3.58±0.19(stat)±0.39(syst)]×10^{-6}. For the B_{s}^{0} meson, the result is much higher than the expected value of O(10^{-9}). The small available phase space in these decays also allows for the most precise single measurement of both the B^{0} mass as 5279.74±0.30(stat)±0.10(syst)  MeV and the B_{s}^{0} mass as 5366.85±0.19(stat)±0.13(syst)  MeV.
