Carbapenems, Linezolid, Teicoplanin utilization evaluation in a large teaching based hospital (Shahid Rajaie Heart Center, Tehran): A quality improvement study

The Aim of this study is to access the number of inappropriate usages of post CABG antibiotics such as, Carbapenems, Teicoplanin and Linezolid in Shahid Rajaie Hospital and to apply antibiotic practice guidelines and strategies to reduce inadequate treatment while determining their impact on patient outcomes. This retrospective study was performed at special wards of Shahid Rajaie Hospital. The program was conducted since March to August 2015. All of the patients which were on Imipenem, Meropenem, Linezolide or Teicoplanin as an empiric treatment or based on culture results were considered in the study. The results of this study indicated that among 136 in-patients who had taken at least one of these antibiotics including Imipenem, Meropenem, Linezolide or Teicoplanin, antimicrobial prescription assumed inappropriate for 63 patients (46.32), The most common reason was incorrect dosage (16.39)and the least one was not being drug of choice(2.4).this inappropriateness was occurred mostly in diagnosis of respiratory infection, skin infection and sepsis. The results of this study demonstrates the need for revision in program of prescribing antibiotics in the direction of using antibiotic practice guidelines especially regarding usage of Teicoplanin and Meropenem in specific complication such as respiratory infection and skin infection. � 2016, Oriental Scientific Publishing Company.

Albumin utilization review to evaluate the efficacy and cost, perform as a qualitative study in special wards in Shaheed Rajaei cardiovascular, medical &research center

Drug utilization studies may be one of the major design of optimizing the costeffectiveness of treatment regimens and drugs that used to compare the costs and effects of alternative therapies. Human albumin (HA) is widely used for hypoalbuminemia and other diseases from deficiency of blood and liver factors. HA cost in the clinical setting is still controversial And Since use of albumin an established second line therapy process which is to be used in supportive drug for patients .on this study Trying to find first albumin protocol therapy cost was evaluated Then appropriate practice to be Alternate. A prospective, cross-sectional research was performed in "Shaheed Rajaei" Cardiovascular, Medical and Research Center during a 6-month continuous interval, in which, 300 patients have been evaluated .The study included patients who on a daily basis take albumin from the central pharmacy of Shaheed Rajaei hospital attaints time of receipt drug until discharge from hospital or termination of treatment were studied continuously. Demographic data including dose, intervals and durations have been registered, and then compared with international guidelines such as Data analyses have been done by SPSS 16 software. The results of this study indicated that among 300 in-patients who had prescribed albumin prescription assumed inappropriate for 281 patients (93.7), The most common reason was incorrect indication of prescription without checking serum albumin level (56.39) .base on this study the most reasons of albumin use were ascites and edema (57.9),during the course of CABG(27.5),hypoalbuminemia and hypoproteinemia(33.3),acute nephritis(17.6),hemodialysis(19.6). also rate of infusion error was (16.5 )and error related to dosages of order was ( 23.8 ).according to guidelines dosage of adminstration must be base on weight and serum albumin level that not be considred in intensive wards. According to data from this study suggests that You can see the protocol therapy based on the patient's needs Albumin consumption to reduce the cost of treatment and The lack of effectiveness of the drug, especially compared to other alternative medicines reduced

Measurement of the Branching Fraction for B- --> D0 K*-

We present a measurement of the branching fraction for the decay B- --> D0 K*- using a sample of approximately 86 million BBbar pairs collected by the BaBar detector from e+e- collisions near the Y(4S) resonance. The D0 is detected through its decays to K- pi+, K- pi+ pi0 and K- pi+ pi- pi+, and the K*- through its decay to K0S pi-. We measure the branching fraction to be B.F.(B- --> D0 K*-)= (6.3 +/- 0.7(stat.) +/- 0.5(syst.)) x 10^{-4}.Comment: 7 pages, 1 postscript figure, submitted to Phys. Rev. D (Rapid Communications

Evidence for the Rare Decay B -> K*ll and Measurement of the B -> Kll Branching Fraction

We present evidence for the flavor-changing neutral current decay $B\to K^*\ell^+\ell^-$ and a measurement of the branching fraction for the related process $B\to K\ell^+\ell^-$, where $\ell^+\ell^-$ is either an $e^+e^-$ or $\mu^+\mu^-$ pair. These decays are highly suppressed in the Standard Model, and they are sensitive to contributions from new particles in the intermediate state. The data sample comprises $123\times 10^6$ $\Upsilon(4S)\to B\bar{B}$ decays collected with the Babar detector at the PEP-II $e^+e^-$ storage ring. Averaging over $K^{(*)}$ isospin and lepton flavor, we obtain the branching fractions ${\mathcal B}(B\to K\ell^+\ell^-)=(0.65^{+0.14}_{-0.13}\pm 0.04)\times 10^{-6}$ and ${\mathcal B}(B\to K^*\ell^+\ell^-)=(0.88^{+0.33}_{-0.29}\pm 0.10)\times 10^{-6}$, where the uncertainties are statistical and systematic, respectively. The significance of the $B\to K\ell^+\ell^-$ signal is over $8\sigma$, while for $B\to K^*\ell^+\ell^-$ it is $3.3\sigma$.Comment: 7 pages, 2 postscript figues, submitted to Phys. Rev. Let

Measurement of the quasi-elastic axial vector mass in neutrino-oxygen interactions

The weak nucleon axial-vector form factor for quasi-elastic interactions is determined using neutrino interaction data from the K2K Scintillating Fiber detector in the neutrino beam at KEK. More than 12,000 events are analyzed, of which half are charged-current quasi-elastic interactions nu-mu n to mu- p occurring primarily in oxygen nuclei. We use a relativistic Fermi gas model for oxygen and assume the form factor is approximately a dipole with one parameter, the axial vector mass M_A, and fit to the shape of the distribution of the square of the momentum transfer from the nucleon to the nucleus. Our best fit result for M_A = 1.20 \pm 0.12 GeV. Furthermore, this analysis includes updated vector form factors from recent electron scattering experiments and a discussion of the effects of the nucleon momentum on the shape of the fitted distributions.Comment: 14 pages, 10 figures, 6 table

Search for the W-exchange decays B0 --> Ds(*)- Ds(*)+

We report a search for the decays $B^{0} \to D_{s}^{-} D_{s}^{+}$, $B^{0} \to D_{s}^{*-} D_{s}^{+}$, $B^{0} \to D_{s}^{*-} D_{s}^{*+}$ in a sample of 232 million $\Upsilon(4S)$ decays to \BBb ~pairs collected with the \babar detector at the PEP-II asymmetric-energy $e^+ e^-$ storage ring. We find no significant signal and set upper bounds for the branching fractions: ${\cal B}(B^{0} \to D_{s}^{-} D_{s}^{+}) < 1.0 \times 10^{-4}, {\cal B}(B^{0} \to D_{s}^{*-} D_{s}^{+}) < 1.3 \times 10^{-4}$ and ${\cal B}(B^{0} \to D_{s}^{*-} D_{s}^{*+}) < 2.4 \times 10^{-4}$ at 90% confidence level.Comment: 8 pages, 2 figures, submitted to PRD-R

Study of e+e- --> pi+ pi- pi0 process using initial state radiation with BABAR

The process e+e- --> pi+ pi- pi0 gamma has been studied at a center-of-mass energy near the Y(4S) resonance using a 89.3 fb-1 data sample collected with the BaBar detector at the PEP-II collider. From the measured 3pi mass spectrum we have obtained the products of branching fractions for the omega and phi mesons, B(omega --> e+e-)B(omega --> 3pi)=(6.70 +/- 0.06 +/- 0.27)10-5 and B(phi --> e+e-)B(phi --> 3pi)=(4.30 +/- 0.08 +/- 0.21)10-5, and evaluated the e+e- --> pi+ pi- pi0 cross section for the e+e- center-of-mass energy range 1.05 to 3.00 GeV. About 900 e+e- --> J/psi gamma --> pi+ pi- pi0 gamma events have been selected and the branching fraction B(J/psi --> pi+ pi- pi0)=(2.18 +/- 0.19)% has been measured.Comment: 21 pages, 37 postscript figues, submitted to Phys.

Measurement of the cross-section and charge asymmetry of WW bosons produced in proton-proton collisions at s=8\sqrt{s}=8 TeV with the ATLAS detector

This paper presents measurements of the $W^+ \rightarrow \mu^+\nu$ and $W^- \rightarrow \mu^-\nu$ cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS experiment at the LHC and correspond to a total integrated luminosity of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the 1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured with an uncertainty between 0.002 and 0.003. The results are compared with predictions based on next-to-next-to-leading-order calculations with various parton distribution functions and have the sensitivity to discriminate between them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables, submitted to EPJC.
