Introduction: SARS-CoV2 pandemic marks the need to pay attention bacterial pathogens that can complicate hospital stay of patients in intensive care unit (ICU). ESKAPE bacteria which includes Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter cloacae are considered most important, because their close relationship with development ventilator-associated pneumonia (VAP). The aim this work was identify...
The interruption of bacteriological surveillance due to the COVID-19 pandemic brought serious consequences, such as collapse health systems and possible increase in antimicrobial resistance. Therefore, it is necessary know rate resistance its associated mechanisms bacteria causing hospital infections during pandemic. aim this work was show phenotypic molecular characteristics ESKAPE a Mexican tertiary care second third years For purpose, 2021 2022, two hundred unduplicated strains group...
Abstract Patients with pre‐existing liver diseases are considered to have an increased risk of morbidity and mortality from any type infection, including viruses. The aim this work was explore the implications metabolic dysfunction‐associated fatty disease (MAFLD) nonalcoholic (NAFLD) definitions in coronavirus 2019 (COVID‐19) study interaction between advanced fibrosis (AF) each these death intubation patients hospitalized COVID‐19. We performed a retrospective 359 confirmed COVID‐19...
<title>Abstract</title> Purpose Soil-transmitted helminth infections affect people who live in areas with poor sanitation, low socioeconomical level. <italic>Ascaris lumbricoides</italic> is one of the most frequent parasites worldwide and México. The General Directorate Epidemiology reports data related to weekly, this study was based on that. aim analyze SINAVE for twenty years (2003–2022) assess incidence ascariasis United Mexican States. Methods We conducted a retrospective observational...
Some pharmacological properties of the methanolic extract Justicia secunda Vahl leaves (Acanthaceae) were evaluated in Streptozotocin (STZ)-treated albino mice to confirm whether it could be considered an alternative candidate treat diabetes. Using qualitative phytochemistry, alkaloids, flavonoids, and tannins detected. High concentrations DPPH antioxidant activity test conducted vitro presented more than 90% inhibition radical during first minutes reaction. The a slight genoprotective...
Fungi are an important cause of human infection and include infections caused by Candida species. Vaginal candidiasis is a mycosis several species the genus Candida. In Mexico, it considered only that must be reported to health authorities. The participation and/or contribution ALS genes presence cervical cytological alterations currently unknown. purpose this study was elucidate frequency their association with clinical characteristics. number randomly selected samples 697, which 53 were...
An entomological study of triatomine species was carried out to assess their prevalence in 10 localities the state Michoacán, Mexico. Entomological indices were calculated estimate risk for vector-borne transmission Trypanosoma cruzi human population this area. Four (Triatoma barberi, Triatoma dimidiata, Meccus pallidipennis and longipennis) collected from This is first report M. longipennis T. dimidiata Michoacán. significantly (p < 0.05) more abundant than any other Infection greater 50%...
Mechanical ventilators are essential biomedical devices for the respiratory support of patients with SARS-CoV-2 infection. These can be transmitters bacterial pathogens. Therefore, it is necessary to implement effective disinfection procedures. The aim this work was show impact modification a cleaning and method mechanical ventilator-associated pneumonia.A total 338 infected ESKAPE bacteria were divided in two groups. Group A B subjected superoxidation solution-Cl/enzymatic detergent...
Abstract Chagas disease, whose aetiological agent is the protozoan Trypanosoma cruzi , mainly occurs in Latin America. In order to know epidemiology and geographical distribution of this disease Mexico, present work analyses national surveillance data (10 years) for issued by General Directorate Epidemiology (GDE). An ecological analysis (2007–2016) was performed annual reports GDE Mexico. The cases incidence were classified year, state, age group, gender seasons. A map showing generated....
Nanometric materials with biocidal properties effective against severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) and pathogenic bacteria could be used to modify surfaces, reducing the risk of touching transmission. In this work, we showed that a nanometric layer bimetallic AgCu can effectively deposited on polypropylene (PP) fibers. The virucidal nanofilm were evaluated by comparing viral loads remaining uncoated coated PP after contact times between 2 24 h. Quantification virion...
To know the current status of epidemiological and geographic distribution tuberculosis its complication meningeal in Mexico, this work analyzes national surveillance data (ten years) issued by General Directorate Epidemiology (GDE).An observational retrospective analysis monthly annual reports pulmonary cases from January 2007 to December 2017 was performed on GDE Mexico. The number incidence were classified year, state, age group, gender, seasons.A case map generated. During period, a total...
Background. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic is a predisposing factor for the development of healthcare-associated infections, which ventilator-associated pneumonia (VAP) one.Hypothesis. VAP caused by ESKAPE bacteria and other pathogens not detected microbiological culture.Aim. To elucidate bacterial disease 2019 (COVID-19) patients massive sequencing to predict their degree relationship with age sex patients.Methods. Analysis ribosomal libraries...
Antimicrobial resistance in Escherichia coli, one of the causal agents aerobic vaginitis, leads to persistence infection. The investigation integrons acquires relevance, since they are elements that responsible for acquisition antibiotics. aim this work was describe structural diversity class 1 virulent and commensal strains E. coli isolated from patients with vaginal infection.Ninety-two were vaginitis. Resistance profile against 19 antibiotics detected by PCR. identity arrangement...
The purpose of this work was to identify and measure catecholamines, their metabolites, the gene expression catecholamine receptors in osteosarcoma tissue.The levels 3,4-dihydroxyphenylacetic acid, norepinephrine, serotonin, 5-hydroxyindoleacetic acid cancer tissue adjacent non-oncological bone were analysed by high-performance liquid chromatography, dopamine β-hydroxylase, monoaminoxidase, ki67, Runx2 tissue, tumour, bone, human brain RT-PCR.We found significantly higher norepinephrine...
Introduction: Infections acquired in hospitals are the cause of high morbidity and mortality with emergence resistant bacteria, problem is greater. The aim this work was to determine genetic characteristics timeline Klebsiella pneumoniae blaNDM-1 carrying a class 1 integron involved an intrahospital outbreak.
 Methodology: Investigation made from first detection K. blaNDM-1, strain “466”, last clone “423”. 16S rRNA gene analysis showed that 466 clones were related pneumoniae....
One of the priority lines action to contain SARS-CoV-2 pandemic was vaccination programs for healthcare workers. However, with emergence highly contagious strains, such as Omicron variant, it necessary know serological status health personnel make decisions application reinforcements. The aim this work determine seroprevalence against in workers a Mexican hospital after six months administration Pfizer-BioNTech vaccine (two doses, 4 weeks apart) and investigate association between...
