Unraveling the epidemiology of urinary tract infections in neonates: Perspective from a Brazilian NICU.

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.

Impact of intestinal colonization by Gram-negative bacteria on the incidence of bloodstream infections and lethality in critically ill neonates.

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.

Inanimate Surfaces and Air Contamination with Multidrug Resistant Species of Staphylococcus in the Neonatal Intensive Care Unit Environment.

BACKGROUND: Contamination of the hospital environment with multi-resistant (MDR) Staphylococcus increases the risk of infection. The aim of this study is to identify the MDR species of Staphylococcus on inanimate surfaces, in air, and in clinical samples, and analyze the risk factors that correlate with the occurrence of infections in a Neonatal Intensive Care Unit. METHODS: Samples of inanimate surfaces and air were taken using a premoistened swab (0.9% sodium chloride) and spontaneous air sedimentation, respectively. The clinical isolates were recovered from infected neonates. The isolates (environmental and clinical) were identified by matrix-assisted laser desorption ionization-time of flight and the resistance profile was calculated using the disk diffusion agar technique. RESULTS: In total, 181 isolates were obtained, 93 from (surfaces), 18 from the air, and 70 clinical samples. S. epidermidis was the most frequent species (66.8%), and the failure rate in air cleaning was 100%. More than 60% of the isolates were MDR, and the majority of clinical isolates (60.4%) had a resistance profile identical to that of the environmental isolates. CONCLUSION: Staphylococcus spp. were found in most of the analyzed samples, with a high frequency of MDR isolates, demonstrating the importance of the hospital environment as a reservoir, and the need for infection control measures, and rational use of antimicrobials.

ABSTRACT Congenital heart defects (CHD) are among the main causes of morbidity and mortality in infants who has this impairment may present delays in neuropsychomotor development (NPMD). This study assesses the influence of CHD on NPMD of infants. This is an observational study assessing neuropsychomotor development performed by Bayley Scales of Infant and Toddler Development - BSID-III. The Brazilian Economic Classification Criteria was used to verify the socioeconomic status of the families and also the maternal and infants' clinical conditions were verified in the medical discharge report and in the child's health handbook. For the association between the quantitative and qualitative variables with the NPMD, the Spearman's correlation coefficient and the likelihood ratio test were used. A total of 18 infants were assessed, with a predominance of females (72.2%). Most mothers (47.1%) had complete high school or incomplete higher education, with a mean age of 27.2±5.5 years. There was a correlation between the BSID-III scales and the quantitative variables analyzed: motor scale with weight (p=0.02 and r=0.54) and oxygen therapy (p=0.009 and r=−0.591); besides that, the qualitative variables correlation were: motor scale and socioeconomic condition (p=0.015), motor scale and Interatrial Communication - IAC (p=0.023) and language with IAC scales (p=0.038). CHD influences the delay of NPMD, mainly for motor aspect. Furthermore, weight, diagnosis of IAC, use of oxygen therapy and socioeconomic status were considered the main risk factors for the delay in NPMD.

Assessment of the neuropsychomotor development in the first year of life of premature infants with and without bronchopulmonary dysplasia. / Avaliação do desenvolvimento neuropsicomotor de lactentes nascidos prematuros com e sem displasia broncopulmonar no primeiro ano de vida.

OBJECTIVE: To compare the neuropsychomotor development in the first year of life of premature infants with and without bronchopulmonary dysplasia. METHODS: A cross-sectional retrospective study was conducted between January 1, 2014, and December 30, 2015, with premature infants weighing < 1,500g at birth and diagnosed with bronchopulmonary dysplasia at the corrected ages of 6 and 9 months, assessed using the DENVER II Developmental Screening Test. Quantitative variables were described as the means, medians and standard deviations. Variables with normal distribution were tested using Student's t test; otherwise, the Mann-Whitney test was used, considering significance at p-value < 0.05. Qualitative variables were expressed as frequencies and percentages. Logistic regression was used with odds ratio analysis to evaluate the effects of other variables as risk factors for changes in neuropsychomotor development. RESULTS: Infants with bronchopulmonary dysplasia showed greater developmental delay compared with those without bronchopulmonary dysplasia (p-value = 0.001). The factors associated with a higher incidence of changes in neuropsychomotor development, in addition to bronchopulmonary dysplasia, were antenatal steroid, gender, birth weight, 5-minute Apgar score, Score for Neonatal Acute Physiology-Perinatal Extension, duration of oxygen therapy, duration of mechanical ventilation and length of hospital stay. Other variables may also have influenced the result, such as drug use by mothers of infants with bronchopulmonary dysplasia. CONCLUSION: Bronchopulmonary dysplasia associated with other pre- and postnatal factors may be considered a risk factor for delayed neuropsychomotor development in the first year of life in premature infants born weighing less than 1,500g.

Influência do ambiente domiciliar no desenvolvimento motor de lactentes com síndrome de Down / Influencia del ambiente domiciliar en el desarrollo motor de bebés con síndrome de Down / Influence of the home environment on the motor development of infants with Down syndrome

RESUMO Crianças com síndrome de Down apresentam atrasos no desenvolvimento neuropsicomotor relacionados a tônus muscular, controle postural e equilíbrio. O desenvolvimento motor sofre interferência multifatorial, que envolve características biológicas, psicológicas, sociais e ambientais. Assim, o ambiente em que o lactente está incluído pode atuar como facilitador do desenvolvimento neuropsicomotor. O objetivo deste estudo foi avaliar a influência do ambiente domiciliar no desenvolvimento motor de lactentes com síndrome de Down. Participaram do estudo 16 lactentes com a síndrome, divididos em grupo I (3 a 11 meses) e grupo II (12 a 18 meses), avaliados pela Alberta Infant Motor Scale (AIMS) e pelo questionário Affordances in the Home Environment for Motor Development - Infant Scale (AHEMD-IS). A análise de dados foi feita por meio do teste de Kruskal-Wallis, coeficiente de correlação de Spearman e teste de razão de verossimilhança. Os resultados evidenciaram uma correlação positiva significativa entre o escore bruto da AIMS e a variedade de estímulos (p=0,01, r=0,78) e com o escore total do questionário AHEMD-IS (p=0,02, r=0,74) no grupo II. Verificou-se, ainda, correlação entre a renda familiar e as oportunidades com brinquedos de função motora grossa (p=0,05, r=0,49), porém com correlação fraca. Conclui-se que o ambiente domiciliar tem importante papel no desenvolvimento motor de crianças com síndrome de Down entre 12 e 18 meses, por proporcionar oportunidades de vivências e experimentações. Assim, pode-se afirmar que ambientes mais adequados proporcionam melhor desempenho motor.

RESUMEN Los niños con síndrome de Down presentan retraso en el desarrollo neuropsicomotor, relacionado con el bajo tono muscular, el control postural y el equilibrio. El desarrollo motor sufre interferencias multifactoriales, que involucra características biológicas, psicológicas, sociales y ambientales. Por lo tanto, el ambiente en el que se incluye el bebé puede actuar como un facilitador del desarrollo neurológico. El objetivo de este estudio fue evaluar la influencia del ambiente familiar en el desarrollo motor de los niños con síndrome de Down. El estudio incluyó 16 bebés con síndrome de Down, divididos en el grupo I (3-11 meses de edad) y el grupo II (12-18 meses de edad), evaluada por Alberta Infant Motor Scale (AIMS) y por Affordances in the Home Environment for Motor Development questionnaire Infant-Scale (AHEMD-IS). El análisis de datos se realizó mediante la prueba de Kruskal-Wallis, coeficiente de correlación de Spearman y la prueba de razón de verosimilitud. Los resultados mostraron una relación positiva significativa entre la puntuación bruta de AIMS y la variedad de estímulos (p=0,01, r=0,78) y la puntuación total del cuestionario AHEMD-IS (p=0,02, r=0,74) en el grupo II. También se verificó relación entre la renta familiar y las oportunidades con juguetes de función motora gruesa (p=0,05, r=0,49), pero con pobre correlación. Se concluye que el ambiente familiar tiene un papel importante en el desarrollo motor de los niños con síndrome de Down, entre 12 y 18 meses, así que proporciona oportunidades para las vivencias y experiencias. Ambientes más adecuados proporcionan un mejor rendimiento del desarrollo motor.

ABSTRACT Children with Down syndrome present impairments in neuro-psychomotor development, which are related to muscle tone, postural control and balance. Motor development is influenced by biological, psychological, social and environmental factors. Thus, the environment in which the infant is in can facilitate the neuro-psychomotor development. The objective of this study was to evaluate the influence of the home environment on the motor development of infants with Down syndrome. Sixteen infants with Down syndrome were divided into Group I (3 to 11 months of age) and Group II (12 to 18 months of age), evaluated by the Alberta Infant Motor Scale (AIMS) and the Affordances in the Home Environment for Motor Development Infant-Scale (AHEMD-IS) questionnaire. Data analysis was performed using the Kruskall-Wallis test, Spearman's correlation coefficient and the likelihood ratio test. The results showed a significant positive relationship between the gross AIMS score and the variety of stimuli (p=0.01, r=0.78) and with the AHEMD-IS questionnaire score (p=0.02, r=0.74) in Group 2. Family income and affordances with motor function toys (p=0.05, r=0.49) were also correlated, but the correlation was weak. The home environment plays an important role in the motor development of children with Down syndrome aged between 12 and 18 months, as it provides opportunities for experiencing and experimenting. Better suited environments provide better motor performance.

Características do desenvolvimento neuropsicomotor de lactentes filhos de mães que fizeram uso de drogas durante a gestação / Neuropsychomotor development characteristics of the infants who born from women who used drugs during pregnancy

INTRODUCTION: The use of street drugs during pregnancy, due to their deleterious effects on the health of the infant, may have clinical implications for neuropsychomotor development. OBJECTIVE: The aim of this study was to analyse the characteristics of the neuropsychomotor development of infants born from women who used street drugs during pregnancy. METHODS: A cross-sectional retrospective study was carried out. A total of 51 medical records of infants weighing less than 1.500 grams, who were born in the Hospital de Clínicas da Universidade Federal de Uberlândia (HC/UFU), Minas Gerais, Brazil, from January 2014 to December 2015 were analysed. Using the Development Screening test Denver II at 6 or 9 months of corrected age performed the neuropsychomotor development evaluation. Statistical analysis included quantitative variables that were described by means of average, medians and standard deviation. Groups were compared by the t test or Mann-Whitney test. The associations of the qualitative variables were evaluated by means of the likelihood ratio test. RESULTS: Of the 51 records analysed, 39.2% belong to the group of children of mothers who used street drugs and 60.8% belong to the group of children of nonuser mothers. The neuropsychomotor development was predominantly abnormal and with a significant difference in the general performance classification (p<0.001) and, specifically, in the coarse motor area (p = 0.003) in the group of infants born to mothers who used street drugs. CONCLUSION: Infants of mothers who used street drugs had a greater delay in neuropsychomotor development.

Analysis of the presence of filling material in oval root canals using computed microtomography after endodontic retreatment performed by different techniques

The aim of this study was to evaluate the presence of filling material in oval root canals after endodontic retreatment performed by different techniques, considering the area (mm2), location and root third using computed microtomography (µ-CT). Methods: Thirty human lower central incisor underwent biomechanical preparation, root filling and filling removal using two techniques (n=15): MN- manual retreatment technique (Gates Glidden burs and stainless steel manual files); and RT- rotary retreatment technique (ProTaper Universal and ProTaper Retreatment Systems). Cross-sectional images of the teeth were made using µ-CT to identify the presence of remaining filling in all root thirds of the canal walls. The remaining material detected in 150 µ-CT sections was identified and its area quantified (mm2) for each root third individually. Results: Data analysis showed no difference in the remaining area of filling material (p=0.8611) for the both techniques. Higher frequency of remaining material was verified in the lingual wall of the root canals. Regardless of the retreatment technique, the apical third showed lager areas of remaining filling material. More areas of remaining material were detected in the cervical third of the RT group, whereas for the MN group, most areas were observed in the middle and apical thirds. Conclusion: According to our results, no significant differences were verified between the efficiency of the rotary and manual techniques for removing filling material due to the interferences caused by the root canal anatomy (AU)

The epidemiology of cryptococcosis and the characterization of Cryptococcus neoformans isolated in a Brazilian University Hospital.

Cryptococcosis, a systemic disease caused by the fungus Cryptococcus neoformans/ Cryptococcus gattii is more severe in immunocompromised individuals. This study aimed to analyze the epidemiology of the disease, the molecular characteristics and the antifungal susceptibility of C. neoformans isolated from patients treated in a Brazilian university hospital. This retrospective study was conducted in the Clinical Hospital, Federal University of Uberlândia, and evaluated cases of cryptococcosis and strains of C. neoformans isolated from 2004 to 2013. We evaluated 41 patients, 85% of whom were diagnosed with AIDS. The fungus was isolated from the cerebrospinal fluid (CSF) of 21 patients (51%); 19.5% had fungemia and in 24% the agent was isolated from the CSF and blood, concurrently. Meningoencephalitis was the most frequent (75%) manifestation of infection. Despite adequate treatment, the mortality of the disease was 58.5%. Most isolates (97.5%) presented the VNI genotype (serotype A, var. grubii) and one isolate was genotyped as C. gattii (VGI); all the isolates were determined as mating type MATa and showed susceptibility to the tested antifungals (fluconazole, voriconazole, amphotericin B and 5-flucytosine). Although AIDS detection rates remain stable, opportunistic infections such as cryptococcosis remain as major causes of morbidity and mortality in these patients.

Selection of mango rosa genotypes in a breeding population using the multivariate-biplot method / Seleção de genótipos em uma população de melhoramento de manga rosa usando o método multivariado biplot

ABSTRACT: Mango ( Mangifera indica L.) trees stand out among the main fruit trees cultivated in Brazil. The mango rosa fruit is a very popular local variety (landrace), especially because of their superior technological characteristics such as high contents of Vitamin C and soluble solids (SS), as well as attractive taste and color. The objective of this study was to select a breeding population of mango rosa (polyclonal variety; ≥5 individuals) that can simultaneously meet the fresh and processed fruit markets, using the multivariate method of principal components and the biplot graphic. The principal components, biplot graphic, and phenotype correlations were obtained using the R (2012) software. Pulp percentage and the pulp, skin, and seed mass variables can be indirectly selected using the smallest fruit diameter, which allowed an easier measurement. The P23R AREA3, P30R AREA3, and P32R AREA3 genotypes are selection candidates due to the presence of alleles, which are important agro-technological traits for mango breeding. This study showed that the biplot analysis is a valuable tool for decision making and visualization of interrelationships between variables and genotypes, facilitating the mango selection process.

RESUMO: Dentre as principais fruteiras cultivadas no Brasil, destaca-se a mangueira ( Mangifera indica L.). A manga rosa é uma variedade local bastante apreciada, especialmente devido a suas características tecnológicas superiores, tais como alto teor de Vitamina C, conteúdo de sólidos solúveis totais (SS), bem como sabor e cor atraentes. O objetivo deste estudo foi selecionar uma população de melhoramento de manga rosa (variedade policlonal; ≥5 indivíduos) que atenda simultaneamente aos mercados de frutas frescas e processadas, empregando o método multivariado de componentes principais e o gráfico biplot. Os componentes principais, o gráfico biplot e as correlações fenotípicas foram obtidos usando o software R (2012). As variáveis porcentagem de polpa e as massas de polpa, casca e semente podem ser selecionadas indiretamente por meio do diâmetro menor do fruto, que permite uma mensuração mais fácil. Os genótipos P23R ÁREA3, P30R ÁREA3, e P32R ÁREA3 são candidatos à seleção devido à presença de alelos para caracteres agrotecnológicos, que são importantes para o melhoramento da manga. Este estudo mostrou que a análise biplot é uma ferramenta valiosa para a tomada de decisão e visualização das inter-relações entre variáveis e genótipos, facilitando o processo seletivo da manga.

RELATED FACTORS FOR COLONIZATION BY Candida SPECIES IN THE ORAL CAVITY OF HIV-INFECTED INDIVIDUALS.

UNLABELLED: The colonization of the oral cavity is a prerequisite to the development of oropharyngeal candidiasis. AIMS: The aims of this study were: to evaluate colonization and quantify Candida spp. in the oral cavity; to determine the predisposing factors for colonization; and to correlate the levels of CD4+ cells and viral load with the yeast count of colony forming units per milliliter (CFU/mL) in HIV-positive individuals treated at a University Hospital. Saliva samples were collected from 147 HIV patients and were plated on Sabouraud Dextrose Agar (SDA) and chromogenic agar, and incubated at 30 ºC for 72 h. Colonies with similar morphology in both media were counted and the result expressed in CFU/mL. RESULTS: Of the 147 HIV patients, 89 had positive cultures for Candida spp., with a total of 111 isolates, of which C. albicans was the most frequent species (67.6%), and the mean of colonies counted was 8.8 × 10³ CFU/mL. The main predisposing factors for oral colonization by Candida spp. were the use of antibiotics and oral prostheses. The use of reverse transcriptase inhibitors appears to have a greater protective effect for colonization. A low CD4+ T lymphocyte count is associated with a higher density of yeast in the saliva of HIV patients.
