An elevated quantity of pathogenic microorganisms can be an indicator of poor air quality, putting patient's health in hospitals at risk. The sanitation of the refrigeration systems must be carried out efficiently and with the right products, capable of maintaining reduced levels of hospital infection. In this work, the aim was to analyze the fungal density in the air of a private hospital, located in João Pessoa-PB, Brazil. The effectiveness of the disinfectant used to clean air conditioning systems in these environments was also verified. In an in vitro experiment with Thilex ® disinfectant against common microorganisms in the hospital environment, the antimicrobial activity, concentration and time of action were evaluated. For the analysis of the air in refrigerated places in the hospital, a bio-aerosol impactor was used to quantify the pathogens. The antimicrobial test indicated that Thilex ® was effective against Klebsiella sp., Escherichia coli and Candida albicans, while Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus sp. and Aspergillus sp. presented resistance at the concentration of 2%, being controlled up to 20% of the product in distilled water and exposure time above 1 minute. The hospital's air samples indicated that 12 of the 23 rooms had a fungal density above the acceptable limit according to the current national regulatory standard, with a higher prevalence in obstetrics rooms. The most common genera were Aspergillus sp., Penicillium sp. and Monilia sp. These results indicate urgency in the development of more effective public policies in reducing the risk to patients exposed to low air quality in hospitals.
Makeup is used by a large portion of humanity and often misused or stored incorrectly, leading to contamination by microbes. The water content in cosmetics influences susceptibility to microbial contamination, which can represent health risks, as well as deterioration. The aim of this work was to isolate and identify filamentous fungi in samples of face powder, foundation, blush, and lipstick of eight popular brands in Brazil. A study of their composition identified a total of 106 ingredients. Of the products, 75% of the samples showed contamination by filamentous fungi. Penicillium was the most prevalent, followed by Rhizopus and Scopulariopsis. The presence of these pathogens suggests misuse in the production and manipulation of these cosmetics as well as high risk to users' health.
The habit of diluting cleaning solutions is routinely practiced in many homes and facilities around the world every day. The aim of the present work was to analyze the antimicrobial effect on six pathogenic microorganisms transmitted by hand on the two most commonly diluted cleaning solutions used in the state of Paraíba (Brazil). This practice was identified by means of a questionnaire. The cleaning solutions were diluted in
Sepsis is a potentially fatal clinical syndrome characterized by an abnormal response to infection associated with organic dysfunction. It is a relevant cause of admission to intensive care units (ICUs) and related to increased morbidity and mortality rates. This study aimed to evaluate the epidemiological profile of adult ICU patients of Lauro Wanderley University Hospital (HULW) in the municipality of João Pessoa (PB) to determine the risk factors associated with increased mortality in patients with sepsis. This retrospective and observational methodological study evaluated the epidemiological profile and characteristics of patients with sepsis, aiming to analyze the risk factors related to increased mortality. The mortality risk analysis was performed in two parts. The first was made from Pearson's chi-square test to determine the association between categorical
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
