Conciliação medicamentosa em hospital universitário: estratégia de segurança em pacientes neurocirúrgicos / Medication reconciliation in a university hospital: safety strategy in neurosurgical patients / Conciliación de medicamentos en un hospital universitario: estrategia de seguridad en pacientes neuroquirúrgicos

Esse trabalho teve como objetivo identificar as discrepâncias medicamentosas, por meio do serviço de conciliação de medicamentosa, em pacientes admitidos na clínica cirúrgica de uma unidade especializada no atendimento de doença relacionadas ao sistema neuromuscular na cidade de Manaus, Amazonas. Trata-se de um estudo descritivo e prospectivo, realizado no período de setembro a dezembro de 2020 em pacientes submetidos a conciliação medicamentosa. Na primeira etapa realizou-se a anamnese farmacêutica em formulário semiestruturado e foi elaborada a melhor história possível de medicamentos (MHPM). Os medicamentos prescritos na admissão foram comparados com a MHPM e as discrepâncias foram identificadas e classificadas quanto a intencionalidade e tipo. Ao total 54 pacientes foram incluídos no estudo, sendo que para 32 foi realizada a conciliação medicamentosa por usarem medicamentos de uso contínuo. Foram identificadas 20 discrepâncias intencionais, 3 discrepâncias intencionais não documentadas e 12 discrepâncias não intencionais. Omissão de medicamentos foi o tipo de discrepância mais comum (86%). Diante do exposto, concluímos que a conciliação medicamentosa mostrou-se um importante recurso para identificação de discrepâncias na transição de cuidado de pacientes com doenças neurológicas, principalmente no que se refere à omissão de medicamentos. As intervenções farmacêuticas a partir das discrepâncias encontradas, conseguiram mitigar erros de medicação e possíveis eventos adversos, aumentando a segurança do paciente.

This work aimed to identify medication discrepancies, through the medi- cation reconciliation service, in patients admitted to the surgical clinic of a unit special- ized in treating diseases related to the neuromuscular system in the city of Manaus, Ama- zonas. This is a descriptive and prospective study, carried out from September to Decem- ber 2020 in patients undergoing medication reconciliation. In the first stage, the pharma- ceutical anamnesis was carried out in a semi-structured form and the best possible medi- cation history (MHPM) was prepared. Medications prescribed on admission were com- pared with the MHPM and discrepancies were identified and classified according to in- tentionality and type. 54 patients were included in the study, and for 32 medication rec- onciliation was performed because they used continuous medication. A total of 20 inten- tional discrepancies, 3 intentional undocumented discrepancies and 12 unintentional dis- crepancies were identified. Medication omission was the most common type of discrep- ancy (86%). We conclude that medication reconciliation proved to be an important re- source for identifying discrepancies in the transition of care for patients with neurological diseases, especially with regard to medication omission. Pharmaceutical interventions, based on the discrepancies found, managed to mitigate medication errors and possible adverse events, increasing patient safety.

Detection and analysis of different interactions between resistance mechanisms and carbapenems in clinical isolates of Klebsiella pneumoniae

Abstract Carbapenems are considered last-line agents for the treatment of serious infections caused by Klebsiella pneumoniae, and this microorganism may exhibit resistance to β-lactam antibiotics due to different mechanisms of resistance. We evaluated 27 isolates of K. pneumoniae resistant to carbapenems recovered from inpatients at the University Hospital of Santa Maria-RS from July 2013 to August 2014. We carried out antimicrobial susceptibility, carbapenemase detection, testing for the presence of efflux pump by broth microdilution and loss of porin by sodium dodecyl sulfate polyacrylamide gel electrophoresis. Genetic similarity was evaluated by ERIC-PCR. High levels of resistance were verified by the minimum inhibitory concentration for the antimicrobials tested. The blaKPC gene was present in 89% of the clinical isolates. Blue-Carba and combined disk with AFB tests showed 100% concordance, while the combined disk test with EDTA showed a high number of false-positives (48%) compared with the gold-standard genotypic test. Four isolates showed a phenotypic resistance profile consistent with the overexpression of the efflux pump, and all clinical isolates had lost one or both porins. The ERIC-PCR dendrogram demonstrated the presence of nine clusters. The main mechanism of resistance to carbapenems found in the assessed isolates was the presence of the blaKPC gene.

In Vitro Evaluation of the Antimicrobial and Antimycobacterial Activities of Solanum guaraniticum A. St.-Hil. Leaves.

With the emergence of antimicrobial resistance, it becomes necessary to search for new alternatives for the treatment of infectious diseases. Solanum guaraniticum is a shrub known as jurubeba or false jurubeba that has hepatoprotective and antioxidant activities, used in popular medicine for the treatment of various diseases. The aim of this study was to evaluate the in vitro antimicrobial and antimycobacterial activities of crude extract, chloroforn, ethyl acetate and butanol fractions from its leaves. Good activities were observed for the ethyl acetate fraction against Staphylococcus intermedius and Listeria monocytogenes (MIC = 64 μg/mL) and for the crude extract against Micrococcus luteus (MIC = 32 μg/mL). In general, the extracts showed moderate activity against Gram-positive bacteria, and were inactive against Gram-negative bacteria and fungi. It was also verified considerable activity against Mycobacterium smegmatis, mainly by chloroform fraction (MIC = 156 μg/mL). These results are probably due to the good antioxidant activity and to the presence of high contents of polyphenols, tannins and alkaloids, metabolites known to possess antimicrobial activity. Studies aiming the isolation of compounds are necessary in order to know the main component involved in these activities, since the plant has an antimicrobial potential.

Identification of mycobacteria isolated at University Hospital of Santa Maria, Rio Grande do Sul, Brazil / Identificação de micobactérias isoladas no Hospital Universitário de Santa Maria, Rio Grande do Sul, Brasil

This study evaluated the prevalence of nontuberculous mycobacterium (NTM) in relation to the total number of cases of mycobacterial infections detected in patients admitted at the University Hospital of Santa Maria from 2008 to 2010. From the positive samples for the genus Mycobacterium, 67% belonged to the Mycobacterium tuberculosis complex (MTBC) and 33% of them were classified as NTM. This investigation aims to contribute to the epidemiology of mycobacterioses, inasmuch as patients infected by NTM require distinctive treatment and monitoring in comparison with those infected by MTBC.

Foi avaliada a prevalência de micobactérias não tuberculosas (MNT) em relação ao total de casos de micobacterioses identificadas em pacientes do Hospital Universitário de Santa Maria, entre os anos de 2008 e 2010. Entre as amostras positivas para o gênero Mycobacterium, 67% eram do complexo Mycobacterium tuberculosis (CMTB) e 33% foram classificadas como MNT. Este estudo procura contribuir com a epidemiologia das micobacterioses, uma vez que os pacientes infectados por MNT necessitam de tratamento e acompanhamento diferenciado dos infectados pelo CMTB.
