POTENTIAL DRUG INTERACTIONS IN AN INTENSIVE CARE UNIT INSIDE MINAS GERAIS: A CROSS-SECTION STUDY

A interação medicamentosa é definida como evento em que um medicamento sofre ou ocasiona alguma alteração decorrente da administração de outro medicamento, alimento ou recurso diagnóstico. Pacientes atendidos por unidades de terapia intensiva (UTIs) fazem uso de diversos recursos terapêuticos, dentre eles os medicamentos que podem propiciar potenciais interações fármaco-fármaco (pIFFs). Desta forma, o objetivo deste estudo é determinar a prevalência de pIFFs em prescrições médicas de um grupo pacientes atendidos por uma UTI de um hospital privado do interior de Minas Gerais. Para isso, conduziu-se um estudo de caráter quantitativo e de natureza descritiva transversal em uma UTI, analisando de uma a cinco prescrições diárias de pacientes admitidos no período de dezembro de 2019 a março de 2020. Dados de 57 pacientes foram incluídos, sendo 36 (63%) do sexo feminino e 21 (37%) do sexo masculino, com média de idade de 70,6 anos. Foram analisadas 199 prescrições no software Micromedex®, o que representa uma média de 3,5 prescrições analisadas por paciente. Ao menos uma pIFF foi detectada em prescrições de 48 pacientes, totalizando uma prevalência de 84% na amostra analisada. Dentre as pIFFs encontradas foram mais prevalentes aquelas classificadas com severidade maior (55%) e documentação razoável (67%), de acordo com o Micromedex®. Houve correlação estatística entre o número de medicamentos e a prevalência de pIFFs (ρ = 0,784; p < 0,001). A prevalência de pIFFs na amostra analisada por este estudo foi elevada. A análise das prescrições médicas pelo Farmacêutico pode possibilitar a detecção das pIFFs.   Descritores: Interação medicamentosa. Assistência farmacêutica.

Patients treated by intensive care units (ICUs) make use of several therapeutic resources, including medications that can provide potential drug-drug interactions (pDDIs). Thus, the aim of this study is to determine the prevalence of pDDIs in medical prescriptions for a group of patients treated by an ICU of a private hospital in the interior of Minas Gerais. For this, a quantitative and descriptive cross-sectional study was conducted in an ICU, analyzing from one to five daily prescriptions of patients admitted from December 2019 to March 2020. Data from 57 patients were included, 36 (63%) of which were female and 21 (37%) were male, with a mean age of 70,6 years. 199 prescriptions were analyzed using the Micromedex® software, which represents an average of 3,5 prescriptions analyzed per patient. At least one pDDI was detected in prescriptions of 48 patients, with a total prevalence of 84%. Among the pDDIs found, those with major severity (55%) and fair documentation (67%) were more prevalent. There was a statistical correlation between the number of drugs and the prevalence of pDDIs (ρ = 0,784; p <0,001). The prevalence of pDDIs in the sample analyzed by this study was high. The analysis of medical prescriptions by the pharmacist can make it possible to detect pDDIs.   Descriptors: Drug interaction. Pharmaceutical services. Intensive care unit

Interações medicamentosas em unidades de terapia intensiva do Brasil: Revisão integrativa/ Drug interactions in intensive care units in Brazil: Integrative review

A interação medicamentosa é a modificação, aumento ou diminuição do efeito de um fármaco diante de sua administração com outro fármaco. No ambiente de unidade de terapia intensiva (UTI) se faz necessário significante uso de medicamentos que podem propiciar eventos adversos como aqueles referentes aos resultados de potenciais interações fármaco-fármaco (pIFFs). Desta forma, o presente estudo tem como objetivo avaliar as características associadas às pIFFs em pacientes internados em UTIs do Brasil. Para isso, conduziu-se uma revisão integrativa nas bases de dados da Lilacs e Medline, onde se selecionou artigos científicos publicados nos anos de 2010 a 2020. Ao final da busca na literatura, foram incluídos oito artigos nesta revisão integrativa. O número de pacientes analisados nos estudos variou de 59 a 1124, atendidos por diferentes UTIs brasileiras. A idade média variou de 50 a 61 anos e houve maior predominância de indivíduos do sexo masculino. A prevalência de pIFFs foi alta na maior parte da literatura analisada. A interação de severidade moderada foi a mais encontrada e três estudos encontraram contraindicações nas prescrições analisadas. O fator mais associado às pIFFs foi o número de medicamentos. O par de interações mais encontrado foi o relacionado ao Fentanil e Midazolam. Conclui-se que os dados, ainda que extraídos de fontes heterogêneas, permitem a detecção das características associadas à problemática que envolve as pIFFs em UTIs

Measurement of the forward Z boson production cross-section in pp collisions at s=13\sqrt{s} = 13 TeV

A measurement of the production cross-section of Z bosons in pp collisions at $\sqrt{s} = 13$ TeV is presented using dimuon and dielectron final states in LHCb data. The cross-section is measured for leptons with pseudorapidities in the range $2.0 \eta 4.5$, transverse momenta $p_\text{T} 20$ GeV and dilepton invariant mass in the range $60 m(\ell\ell) 120$ GeV. The integrated cross-section from averaging the two final states is \begin{equation*}\sigma_{\text{Z}}^{\ell\ell} = 194.3 \pm 0.9 \pm 3.3 \pm 7.6\text{ pb,}\end{equation*} where the first uncertainty is statistical, the second is due to systematic effects, and the third is due to the luminosity determination. In addition, differential cross-sections are measured as functions of the Z boson rapidity, transverse momentum and the angular variable $\phi^*_\eta$

Optimizing ddRADseq in non-model species: a case study in Eucalyptus dunnii maiden

Restriction site-associated DNA sequencing (RADseq) and its derived protocols, such as double digest RADseq (ddRADseq), offer a flexible and highly cost-effective strategy for efficient plant genome sampling. This has become one of the most popular genotyping approaches for breeding, conservation, and evolution studies in model and non-model plant species. However, universal protocols do not always adapt well to non-model species. Herein, this study reports the development of an optimized and detailed ddRADseq protocol in Eucalyptus dunnii, a non-model species, which combines different aspects of published methodologies. The initial protocol was established using only two samples by selecting the best combination of enzymes and through optimal size selection and simplifying lab procedures. Both single nucleotide polymorphisms (SNPs) and simple sequence repeats (SSRs) were determined with high accuracy after applying stringent bioinformatics settings and quality filters, with and without a reference genome. To scale it up to 24 samples, we added barcoded adapters. We also applied automatic size selection, and therefore obtained an optimal number of loci, the expected SNP locus density, and genome-wide distribution. Reliability and cross-sequencing platform compatibility were verified through dissimilarity coefficients of 0.05 between replicates. To our knowledge, this optimized ddRADseq protocol will allow users to go from the DNA sample to genotyping data in a highly accessible and reproducible way.Instituto de BiotecnologíaFil: Aguirre, Natalia Cristina.

LHCb upgrade software and computing : technical design report

This document reports the Research and Development activities that are carried out in the software and computing domains in view of the upgrade of the LHCb experiment. The implementation of a full software trigger implies major changes in the core software framework, in the event data model, and in the reconstruction algorithms. The increase of the data volumes for both real and simulated datasets requires a corresponding scaling of the distributed computing infrastructure. An implementation plan in both domains is presented, together with a risk assessment analysis

Physics case for an LHCb Upgrade II - Opportunities in flavour physics, and beyond, in the HL-LHC era

The LHCb Upgrade II will fully exploit the flavour-physics opportunities of the HL-LHC, and study additional physics topics that take advantage of the forward acceptance of the LHCb spectrometer. The LHCb Upgrade I will begin operation in 2020. Consolidation will occur, and modest enhancements of the Upgrade I detector will be installed, in Long Shutdown 3 of the LHC (2025) and these are discussed here. The main Upgrade II detector will be installed in long shutdown 4 of the LHC (2030) and will build on the strengths of the current LHCb experiment and the Upgrade I. It will operate at a luminosity up to 2×1034 cm−2s−1, ten times that of the Upgrade I detector. New detector components will improve the intrinsic performance of the experiment in certain key areas. An Expression Of Interest proposing Upgrade II was submitted in February 2017. The physics case for the Upgrade II is presented here in more depth. CP-violating phases will be measured with precisions unattainable at any other envisaged facility. The experiment will probe b → sl+l−and b → dl+l− transitions in both muon and electron decays in modes not accessible at Upgrade I. Minimal flavour violation will be tested with a precision measurement of the ratio of B(B0 → μ+μ−)/B(Bs → μ+μ−). Probing charm CP violation at the 10−5 level may result in its long sought discovery. Major advances in hadron spectroscopy will be possible, which will be powerful probes of low energy QCD. Upgrade II potentially will have the highest sensitivity of all the LHC experiments on the Higgs to charm-quark couplings. Generically, the new physics mass scale probed, for fixed couplings, will almost double compared with the pre-HL-LHC era; this extended reach for flavour physics is similar to that which would be achieved by the HE-LHC proposal for the energy frontier

Study of the B−→Λc+Λˉc−K−B^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-} decay

The decay $B^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-}$ is studied in proton-proton collisions at a center-of-mass energy of $\sqrt{s}=13$ TeV using data corresponding to an integrated luminosity of 5 $\mathrm{fb}^{-1}$ collected by the LHCb experiment. In the $\Lambda_{c}^+ K^{-}$ system, the $\Xi_{c}(2930)^{0}$ state observed at the BaBar and Belle experiments is resolved into two narrower states, $\Xi_{c}(2923)^{0}$ and $\Xi_{c}(2939)^{0}$, whose masses and widths are measured to be $$m(\Xi_{c}(2923)^{0}) = 2924.5 \pm 0.4 \pm 1.1 \,\mathrm{MeV}, \\ m(\Xi_{c}(2939)^{0}) = 2938.5 \pm 0.9 \pm 2.3 \,\mathrm{MeV}, \\ \Gamma(\Xi_{c}(2923)^{0}) = \phantom{000}4.8 \pm 0.9 \pm 1.5 \,\mathrm{MeV},\\ \Gamma(\Xi_{c}(2939)^{0}) = \phantom{00}11.0 \pm 1.9 \pm 7.5 \,\mathrm{MeV},$$ where the first uncertainties are statistical and the second systematic. The results are consistent with a previous LHCb measurement using a prompt $\Lambda_{c}^{+} K^{-}$ sample. Evidence of a new $\Xi_{c}(2880)^{0}$ state is found with a local significance of $3.8\,\sigma$, whose mass and width are measured to be $2881.8 \pm 3.1 \pm 8.5\,\mathrm{MeV}$ and $12.4 \pm 5.3 \pm 5.8 \,\mathrm{MeV}$, respectively. In addition, evidence of a new decay mode $\Xi_{c}(2790)^{0} \to \Lambda_{c}^{+} K^{-}$ is found with a significance of $3.7\,\sigma$. The relative branching fraction of $B^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-}$ with respect to the $B^{-} \to D^{+} D^{-} K^{-}$ decay is measured to be $2.36 \pm 0.11 \pm 0.22 \pm 0.25$, where the first uncertainty is statistical, the second systematic and the third originates from the branching fractions of charm hadron decays.Comment: All figures and tables, along with any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-028.html (LHCb public pages

Multidifferential study of identified charged hadron distributions in ZZ-tagged jets in proton-proton collisions at s=\sqrt{s}=13 TeV

Jet fragmentation functions are measured for the first time in proton-proton collisions for charged pions, kaons, and protons within jets recoiling against a $Z$ boson. The charged-hadron distributions are studied longitudinally and transversely to the jet direction for jets with transverse momentum 20 $< p_{\textrm{T}} < 100$ GeV and in the pseudorapidity range $2.5 < \eta < 4$. The data sample was collected with the LHCb experiment at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 1.64 fb$^{-1}$. Triple differential distributions as a function of the hadron longitudinal momentum fraction, hadron transverse momentum, and jet transverse momentum are also measured for the first time. This helps constrain transverse-momentum-dependent fragmentation functions. Differences in the shapes and magnitudes of the measured distributions for the different hadron species provide insights into the hadronization process for jets predominantly initiated by light quarks.Comment: All figures and tables, along with machine-readable versions and any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-013.html (LHCb public pages
