From predictions to recommendations:Tackling bottlenecks and overstaying in the Emergency Room through a sequence of Random Forests

One of the goals to improve the quality of care in hospitals is to set a maximum of four hours for patients to be diagnosed and/or receive acute care in the Emergency Room (ER). Unfortunately, this is not always true and some patients overstay. The aim of this work is threefold: (1) to identify which patients will overstay during their admission to the ER; (2) to identify which (pair of) activities might heavily influence the time spent in the ER; and (3) to recommend actions to reduce such time. For that, a sequence of insightful supervised prediction models for generating recommendations is proposed. The method provided makes it possible to generate useful/actionable recommendations for problematic patients based on activities. State of the art techniques did not manage to generate recommendations at the arrival of the patient and/or did not take the interplay between patients into account.</p

The behavior of kinetic parameters in production of pectinase and xylanase by solid-state fermentation

AbstractSolid-state fermentation (SSF) is defined as the growth of microbes without a free-flowing aqueous phase. The feasibility of using a citrus peel for producing pectinase and xylanase via the SSF process by Aspergillus niger F3 was evaluated in a 2kg bioreactor. Different aeration conditions were tested to optimize the pectinase and xylanase production. The best air flow intensity was 1VkgM (volumetric air flow per kilogram of medium), which allowed a sufficient amount of O2 for the microorganism growth producing 265U/g and 65U/g pectinases and xylanases, respectively. A mathematical model was applied to determine the different kinetic parameters related to SSF. The specific growth rate and biomass oxygen yield decreased during fermentation, whereas an increase in the maintenance coefficient for the different employed carbon sources was concurrently observed

A New Strategy To Identify Rare Blood Donors: Single Polymerase Chain Reaction Multiplex Snapshot Reaction For Detection Of 16 Blood Group Alleles

Background. As an alternative to phenotyping, large-scale DNA-based assays, which are feasible for high-throughput donor red blood cell typing, were developed for determination of blood group polymorphisms. However, high-throughput genotyping platforms based on these technologies are still expensive and the inclusion of single nucleotide polymorphisms and analysis of the alleles depend on the manufacturer's determination. To overcome this limitation and in order to develop an assay to enable the screening of rare donors, we developed a SNaPshot assay for analysis of nine single nucleotide polymorphisms related to antigens that are difficult to assess using conventional serology. Materials and methods. The single polymerase chain reaction multiplex SNaPshot reaction was optimized to identify nine single nucleotide polymorphisms determining 16 alleles: KEL*3/KEL*4, KEL*6/KEL*7, DI*1/DI*2, DI*3/DI*4, YT*1/YT*2, CO*1/CO*2, DO*1/DO*2, DO*4, DO*5. We designed a single multiplex PCR with primers encompassing the blood group single nucleotide polymorphisms and performed an internal reaction with probe primers able to discriminate the alleles after fragment analysis. The SNaPshot assay was validated with 140 known alleles previously determined by PCR restriction fragment length polymorphism. Results. We were able to simultaneous detect nine single nucleotide polymorphisms defining 16 blood group alleles on an assay based on a multiplex PCR combined with a single base extension using genomic DNA. Discussion. This study demonstrates a robust genotyping strategy for conducting rare donor screening which can be applied in blood centers and could be an important tool for identifying antigen-negative donors and, therefore, for providing rare blood. © SIMTI Servizi Srl.12SUPPL.1s256s263Jungbauer, C., Routine use of DNA testing for red cell antigens in blood centres (2011) Transfus Apher Sci, 45, pp. 61-68Nance, S.T., How to find, recruit and maintain rare blood donors (2009) Curr Opin Hematol, 16, pp. 503-508Veldhuisen, B., Van Der Schoot, C.E., De Haas, M., Blood group genotyping: From patient to high-throughput donor screening (2009) Vox Sang, 97, pp. 198-206Moulds, J.M., Future of molecular testing for red blood cell antigens (2010) Clin Lab Med, 30, pp. 419-429Patnaik, S.K., Helmberg, W., Blumenfeld, O.O., BGMUT: NCBI dbRBC database of allelic variations of genes encoding antigens of blood group systems (2012) Nucleic Acids Res, 40, pp. D1023-D1029Vallone, P.M., Butler, J.M., AutoDimer: A screening tool for primer-dimer and hairpin structures (2004) Biotechniques, 37, pp. 226-231Baleotti Jr., W., Rios, M., Reid, M.E., Dombrock gene analysis in Brazilian people reveals novel alleles (2006) Vox Sang, 91, pp. 81-87Rios, M., Hue-Roye, K., Oyen, R., Insights into the Holleyand Joseph- phenotypes (2002) Transfusion, 42, pp. 52-58Baleotti Jr., W., Rios, M., Reid, M.E., A novel DI*A allele without the Band 3-Memphis mutation in Amazonian Indians (2003) Vox Sang, 84, pp. 326-330Arnoni, C., Latini, F.R.M., Person, R.M., Padronização das técnicas de PCR-RFLP para genotipagem dos alelos KEL*3/ KEL*4 e KEL*5/KEL*6 (2011) Rev Bras Hematol Hemoter, 33 (SUPPL.2), pp. 332-488Baleotti Jr., W., Suzuki, R.B., Ruiz, M., A PCR-RFLP strategy for Wright typing (2011) Rev Bras Hematol Hemoter, 33 (SUPPL. 2), pp. 332-488Brazilian Real - United States Dollar Exchange Rate from Central Bank of Brazil, , http://www4.bcb.gov.br/pec/taxas, April 1st to April 30th, 27/03/2013Daniels, G., The molecular genetics of blood group polymorphism (2009) Hum Genet, 126, pp. 729-742Logdberg, L., Reid, M.E., Zelinski, T., Human blood group genes 2010: Chromosomal locations and cloning strategies revisited (2011) Transfus Med Rev, 25, pp. 36-46Di Cristofaro, J., Silvy, M., Chiaroni, J., Bailly, P., Single PCR multiplex SNaPshot reaction for detection of eleven blood group nucleotide polymorphisms: Optimization, validation, and one year of routine clinical use (2010) J Mol Diagn, 12, pp. 453-460Ferri, G., Pelotti, S., Multiplex ABO genotyping by minisequencing (2009) Methods Mol Biol, 496, pp. 51-58Palacajornsuk, P., Halter, C., Isakova, V., Detection of blood group genes using multiplex SNaPshot method (2009) Transfusion, 49, pp. 740-749Silvy, M., Simon, S., Gouvitsos, J., Weak D and DEL alleles detected by routine SNaPshot genotyping: Identification of four novel RHD alleles (2011) Transfusion, 51, pp. 401-411Silvy, M., Di Cristofaro, J., Beley, S., Identification of RHCE and KEL alleles in large cohorts of Afro-Caribbean and Comorian donors by multiplex SNaPshot and fragment assays: A transfusion support for sickle cell disease patients (2011) Br J Haematol, 154, pp. 260-270Pastinen, T., Kurg, A., Metspalu, A., Minisequencing: A specific tool for DNA analysis and diagnostics on oligonucleotide arrays (1997) Genome Res, 7, pp. 606-614Syvanen, A.C., From gels to chips: "Minisequencing" primer extension for analysis of point mutations and single nucleotide polymorphisms (1999) Hum Mutat, 13, pp. 1-10Information notebook (2011) Blood and Hemoderivates Brasília, , Ministério da Saúde.

3β,5α,6β-Trihy­droxy­androstan-17-one

The title compound, C19H30O4, is an androstan-17-one derivative synthesized from the dehydro­epiandrosterone through a sequential addition of an oxidant, followed by a trans-diaxial opening of the epoxide generated, with Bi(OTf)3 (OTf is trifluoro­methane­sulfonate). The six-membered rings have a slightly flattened chair conformation, while the five-membered ring adopts a 14-α envelope conformation. All rings are trans fused. In the crystal, the mol­ecules are connected by O—H⋯O hydrogen bonds involving the hydroxyl and carbonyl groups, forming a three-dimensional network. A quantum mechanical ab initio Roothan Hartree–Fock calculation of the free mol­ecule gives bond lengths, valency angles and ring torsion angles of the free molecule at equilibrium geometry (energy minimum) close to the experimental values

Study of ATLAS sensitivity to FCNC top decays

The ATLAS experiment sensitivity to top quark Flavour Changing Neutral Current (FCNC) decays was studied at LHC using ttbar events. While one of the top quarks is expected to follow the dominant Standard Model decay t->bW, the other decays through a FCNC channel, i.e. t-> Z u(c), t-> gamma u(c) or t-> g u(c). Different types of analyses, applied to each FCNC decay mode, were compared. The FCNC branching ratio sensitivity (assuming a 5sigma signal significance) and 95% confidence level limits on the branching ratios (in the hypothesis of signal absence) were obtained
