ABSTRACT
BACKGROUND: Urinary tract infections (UTIs) can lead to neonatal complications like sepsis, worsened by empirical treatment, contributing to antimicrobial resistance (AMR). This study examined the incidence, etiology, risk factors, and antimicrobial susceptibility of uropathogens in a Neonatal Intensive Care Unit (NICU) in Brazil. METHODS: Medical records of neonates hospitalized in the NICU from January 2015 to June 2022 were retrospectively analyzed through the National Healthcare Safety Network system. RESULTS: Among 1,474 neonates, 3.9% developed UTI, with an alarming 24-fold increase in incidence from 2015 to 2021. Genitourinary complications (odds ratio = 4.8) were a major risk factor. Of the 71 uropathogens, 74.6% were Gram-negative bacteria (GNB), 21.2% Gram-positive bacteria (GPB), and 4.2% Candida albicans. AMR was notable, with 13.3% of GPB and 20.7% of GNB exhibiting multidrug-resistant (MDR), while 6.6% of GPB and 1.9% of GNB showed extensive drug-resistant (XDR). UTI was associated with prolonged hospitalization (16-59 days). In 57 neonates with UTI, 40.3% had bloodstream infections, elevating the risk of death (odds ratio = 1.8). CONCLUSIONS: The study underscores the urgency of implementing infection prevention and control measures in the NICU to curb rising UTI incidences, combat AMR, and mitigate severe complications in critically ill neonates.
ABSTRACT
BACKGROUND: Early detection of antimicrobial-resistant microorganisms is crucial to prevent subsequent invasive infections and contain their spread in the Neonatal Intensive Care Unit (NICU). This study aims to investigate the association between intestinal colonization (IC) by Gram-negative bacteria and the risk of bloodstream infection (BSI) in critically ill neonates. METHODS: Data from the electronic medical records of 678 newborns admitted to a NICU Brazilian between 2018 and 2022 were retrospectively analyzed. Participants were monitored by the National Health Security Network. RESULTS: Among neonates, 6.9 % had IC (56.9 % attributed to Acinetobacter baumannii); of these, 19.1 % developed BSI (66.7 % by Staphylococcus spp.). Within the A. baumannii colonization, 34.5 % occurred during an outbreak in September 2021. Colonized individuals had a longer mean length of stay (49.3 ± 26.4 days) and higher mortality rate (12.8 %) compared to non-colonized individuals (22.2 ± 16.9 days; 6.7 %, respectively). Previous use of antimicrobials and invasive devices significantly increased the risk of colonization. Colonization by drug-resistant microorganisms, along with the occurrence of BSI, was associated with increased mortality and reduced survival time. CONCLUSIONS: IC contributed to the incidence of BSI, leading to more extended hospital stays and higher mortality rates. Its early detection proved to be essential to identify an outbreak and control the spread of resistant microorganisms within the NICU.

A esquistossomose é uma infecção parasitária causada por um grupo de vermes chatos chamados Schistosoma. A doença encontra-se, sobretudo, nos países em desenvolvimento, especialmente nas zonas rurais com más condições de saneamento e acesso limitado à água potável. A esquistossomose é transmitida através do contato com água doce contaminada, como de rios, lagos e lagoas em que vivem as larvas dos parasitas. O objetivo deste artigo foi analisar as variáveis epidemiológicas dos casos (2010-2022) e dos óbitos (2010-2020) por esquistossomose no Brasil. Trata-se de um estudo epidemiológico transversal, descritivo e quantitativo. A estratégia metodológica envolveu análise dos boletins epidemiológicos disponibilizados pelo Sistema de Informação de Agravos de Notificação (Sinan) e pelo Sistema de Informação sobre Mortalidade (SIM) no período de 2010 a 2022. Foram notificados 93.521 casos de esquistossomose e 5.495 óbitos devido a complicações dessa infecção. A forma intestinal foi a mais identificada. Minas Gerais, São Paulo, Bahia e Espírito Santo foram os estados com maior prevalência da doença. Constatou-se que homens pardos com idade entre 20 e 39 anos e com baixo nível de escolaridade são os mais afetados. Identificaram-se 732 casos da infecção em gestantes. Ademais, 62,56% dos casos evoluíram para cura e 5,88% para óbito pelo agravo notificado. Em conclusão, é crucial adotar medidas de prevenção e acesso à educação para combater efetivamente a esquistossomose.
Schistosomiasis is a parasitic infection caused by a group of flatworms called Schistosoma. The disease is primarily found in developing countries, especially in rural areas with poor sanitation and limited access to clean water. Schistosomiasis is transmitted by contact with contaminated freshwater, such as rivers, lakes, and ponds, where the parasites' larvae live. The aim of this article was to analyze the epidemiological variables of schistosomiasis cases (2010-2022) and deaths (2010-2020) in Brazil. This is a cross-sectional, descriptive, and quantitative epidemiologic study. The methodological strategy involved the analysis of epidemiological bulletins provided by the Sistema de Informação de Agravos de Notificação (SINAN) and the Sistema de Informação sobre Mortalidade (SIM) from 2010 to 2022. There were 93.521 reported cases of schistosomiasis and 5.495 deaths due to complications of this infection. The intestinal form was the most identified. Minas Gerais, São Paulo, Bahia, and Espírito Santo were the states with the highest prevalence of the disease. Males, of mixed race, aged between 20 and 39 years, and with a low level of education were the most affected. There were 732 cases of infection in pregnant women. Furthermore, 62.56% of the cases evolved to cure and 5.88% evolved to death by the notified disease. In conclusion, it is crucial to adopt prevention measures and access to education to effectively combat schistosomiasis.
La esquistosomiasis es una enfermedad parasitaria causada por un grupo de platelmintos conocidos como Schistosoma. La enfermedad es más frecuente sobre todo en países en desarrollo, especialmente en zonas rurales con saneamiento deficiente y acceso limitado al agua potable. La transmisión de la esquistosomiasis se da por el contacto con agua dulce contaminada, como ríos, lagos y lagunas donde viven las larvas de los parásitos. El objetivo de este artículo fue analizar las variables epidemiológicas de los casos (2010-2022) y muertes (2010-2020) por esquistosomiasis en Brasil. Se trata de un estudio epidemiológico transversal, descriptivo y cuantitativo. La estrategia metodológica contó con el análisis de los informes epidemiológicos que pone a disposición el Sistema de Información de Enfermedades de Declaración Obligatoria (Sinan) y el Sistema de Información sobre Mortalidad (SIM) en el período de 2010 a 2022. Se notificaron 93.521 casos de esquistosomiasis y 5.495 muertes por complicaciones de esta infección. La forma intestinal fue la más identificada. Minas Gerais, São Paulo, Bahia y Espírito Santo fueron los estados con mayor prevalencia de la enfermedad. Se constató que hombres pardos, de edad entre 20 y 39 años, y bajo nivel de escolaridad son los más afectados. Se identificaron 732 casos de infección en mujeres embarazadas. El 62,56% de los casos evolucionaron a cura; y el 5,88% tuvieron muerte confirmada por el agravio notificado. Se concluye con la necesidad de adoptar medidas de prevención y acceso a la educación para combatir eficazmente la esquistosomiasis.
