1. Effect of ABO blood groups on length of hospital stay according to age in Covid-19 patients
Abstract Introduction Coronavirus Disease 2019 (COVID-19) is a novel viral disease with person-to-person transmission that has spread to many countries since the end of 2019. Although many unknowns were resolved within a year and the vaccine is available, it is still a major global health problem. Objective COVID-19 infection may present with a considerabl

2. The Russian Conduit - Combining Bentall and Ozaki Procedures for Concomitant Ascending Aorta Replacement and Aortic Valve Neocuspidization
Abstract In aortic valve disease cases, prosthetic valves have been used for valve replacement, however, these prostheses have inherent problems, and their quality in some countries is lower comparing to new-generation models, causing shorter durability. Aortic valve neocuspidization (AVNeo) has emerged as an option, which can be applied to a wide spectrum o

3. Aortic Valve Neocuspidization with Glutaraldehyde-Treated Autologous Pericardium (Ozaki Procedure) - A Promising Surgical Technique
Abstract In cases of aortic valve disease, prosthetic valves have been increasingly used for valve replacement, however, there are inherent problems with prostheses, and their quality in the so-called Third World countries is lower in comparison to new-generation models, which leads to shorter durability. Recently, transcatheter aortic valve replacement has

4. High prevalence of CTX-M-1 group in ESBL-producing enterobacteriaceae infection in intensive care units in southern Chile
ABSTRACT Enterobacteria-producing extended-spectrum β-lactamases (ESBL) play an important role in healthcare infections, increasing hospitalization time, morbidity and mortality rates. Among several ESBLs that emerge from these pathogens, CTX-M-type enzymes had the most successful global spread in different epidemiological settings. Latin America presents h

5. Disponibilidade de recursos para tratamento da sepse no Brasil: uma amostra aleatória de instituições brasileiras
RESUMO Objetivo: Caracterizar a disponibilidade de recursos a partir de amostra aleatória representativa das unidades de terapia intensiva do Brasil. Métodos: Realizou-se um questionário estruturado on-line para ser respondido pelo diretor médico de cada unidade participante do estudo SPREAD (Sepsis PREvalence Assessment Database), um estudo de preval�

6. Molecular farming of antimicrobial peptides: available platforms and strategies for improving protein biosynthesis using modified virus vectors
Abstract The constant demand for new antibiotic drugs has driven efforts by the scientific community to prospect for peptides with a broad spectrum of action. In this context, antimicrobial peptides (AMPs) have acquired great scientific importance in recent years due to their ability to possess antimicrobial and immunomodulatory activity. In the last two dec

7. Clonal relationships, antimicrobial susceptibilities, and molecular characterization of extended-spectrum beta-lactamase-producing Escherichia coli isolates from urinary tract infections and fecal samples in Southeast Iran
Abstract INTRODUCTION: Multidrug-resistant (MDR) Escherichia coli, a species that is a leading cause of urinary tract infections (UTIs) and is a major global public health concern. This study was designed to detect the differences in antibiotic resistance patterns, the production and type of extended spectrum β-lactamases (ESBLs), and the clonal relationsh

8. CTX-M extended-spectrum β-lactamase-producing Klebsiella spp, Salmonella spp, Shigella spp and Escherichia coli isolates in Iranian hospitals
Abstract This study was conducted in Iran in order to assess the distribution of CTX-M type ESBLs producing Enterobacteriaceae. From January 2012 to December 2013, totally 198 E. coli, 139 Klebsiella spp, 54 Salmonella spp and 52 Shigella spp from seven hospitals of six provinces in Iran were screened for resistance to extended-spectrum cephalosporins. After

9. Emergence of Acinetobacter baumannii ST730 carrying the blaOXA-72 gene in Brazil
Over the last decade, Acinetobacter baumannii resistant to carbapenems has emerged in many medical centres and has been commonly associated with high morbimortality. In Brazil, this resistance is mainly attributed to the spread of OXA-23-producing clones and, to a lesser extent, to OXA-143-producing clones. Here, we describe, for the first time, two OXA-72-p

10. Análise metabolômica via RMN: amostras de urina e látex / Metabolomic analyses by NMR: urine and latex samples
The aim of the first part of this work was to apply the concept of metabolomic analyses in urine samples obtained from humans diagnosed with type 2 diabetes mellitus (T2DM) and impaired glucose tolerance (IGT) and treated with yerba-mate (Ilex paraguariensis) infusions using nuclear magnetic resonance. T2DM is the most recurrent type of diabetes and correspo

11. Estudo da interação de nanotubos de carbono com substrato de quartzo cristalino
Single wall carbon nanotubes (SWNTs) are quasi-onedimensional structures consisting of a rolled up graphene nanoribbon. Due to their unusually large surface-to-volume ratio, SWNTs are strongly affected by the environment. Contact with a supporting substrate modifies their properties, and such interactions have been broadly studied as either a drawback or a s

12. Nosocomial and community infections due to class A extended-spectrum β-lactamase (ESBLA)-producing Escherichia coli and Klebsiella spp. in southern Brazil
OBJECTIVES: To determine the prevalence of class A extended spectrum β-lactamases (ESBL)-producing Escherichia coli and Klebsiella spp., and to investigate clonality among ESBL-producing isolates of nosocomial and community infections. METHODS: The study involved 354 nosocomial infections samples and 992 community infections samples, obtained between 2003 a
