Disponibilidade de recursos e equipamentos complementares para uso na prevenção de infecções relacionadas à assistência à saúde

Background and Objectives: Recently, complementary resources and equipment have emerged to improve prevention of healthcare-associated infections (HAIs). Our aim is to verify availability and use of different resources/equipment by infection controllers. Methods: We conducted a survey with infection controllers from the State of Rio de Janeiro, Brazil, by invitation using a social media group, in August 2022. Nine different resources and equipment were evaluated. Categorical and continuous variables were evaluated by the chi-square test and Mann–Whitney U test, respectively. A p value of less than 0.05 was considered statistically significant. Results: One hundred and eight persons answered the questionnaire. The mean age was 42.8 years (SD +/- 8.5 years) and 53 (49.1%) reported most of their workload in public hospitals, 45 (41.7%) in private hospitals and 10 (9.2%) reported the same workload in public and private hospitals. Sixty-there percent reported teaching activities in their institutions. There was no correlation between the existence of teaching activities and hospital profile (p=0.42). The most common resource available was molecular biology (PCR) for microbiological samples research for 73 (67.6%) participants. The second resource most available was applications (Apps) for HAIs prevention and control for 33 (30.6%), 19 (17.6%) reported no availability of resource/equipment technology. Conclusion: Molecular biology (PCR) for microbiological samples research was the most common resource available for infection controllers of an important state of Brazil.Antecedentes y objetivos: Recientemente han surgido recursos y equipos complementarios para mejorar la prevención de las infecciones asociadas a la atención de la salud.

Effectiveness of antimicrobial stewardship programmes in neonatology: a systematic review

CITATION: Araujo da Silva AR, Marques A, Di Biase C, et al Effectiveness of antimicrobial stewardship programmes in neonatology: a systematic review Archives of Disease in Childhood 2020;105:563-568.Introduction Antimicrobial stewardship programmes (ASPs) are recommended to improve antibiotic use in healthcare and reduce antimicrobial resistance (AMR). Our aim was to investigate the effectiveness of ASPs in reducing antibiotic consumption, use of broad-spectrum/restricted antibiotics, antibiotic resistance and healthcare-associated infections (HAIs) in neonates. Methods We searched PUBMED, SCIELO, EMBASE and the Cochrane Database (January 2000–April 2019) to identify studies on the effectiveness of ASPs in neonatal wards and/or neonatal intensive care units (NICUs). Outcomes were as follows: reduction of antibiotic consumption overall and of broad-spectrum/target antibiotics, inappropriate antibiotic use, antibiotic resistance and HAIs. ASPs conducted in settings other than acute care hospitals, for children older than 1 month, and ASPs addressing antifungal and antiviral agents, were excluded. Results The initial search identified 53 173 titles and abstracts; following the application of filters and inclusion criteria, a total of six publications were included in the final analysis. All studies, of which one was multi-centre study, were published after 2010. Five studies were conducted exclusively in NICUs. Four articles applied multimodal interventions. Reduction of antibiotic consumption overall and/or inappropriate antibiotic use were reported by four articles; reduction of broad-spectrum/targeted antibiotics were reported by four studies; No article evaluated the impact of ASPs on AMR or the incidence of HAI in neonates. Conclusion ASPs can be effectively applied in neonatal settings. Limiting the use of broad-spectrum antibiotics and shorting the duration of antibiotic treatment are the most promising approaches. The impact of ASPs on AMR and HAI needs to be evaluated in long-term studies

Controle de infecções relacionadas à assistência à saúde por bactérias Gram-negativas resistentes à carbapenêmicos em unidade de tratamento intensivo neonatal do Rio de Janeiro.

Justificativa e objetivos. Bactérias Gram-negativas resistentes a carbapenêmicos (BGN-CR) são um problema de saúde pública global, pela possibilidade de causar infecções intratáveis em neonatos. O objetivo foi descrever o controle das taxas de BGN-CR causando infecções relacionadas à assistência à saúde (IRAS) em unidade de tratamento intensivo neonatal (UTINEO). O consumo de antimicrobianos/carbapenêmicos também foi avaliado. Métodos. Estudo prospectivo descritivo das IRAS em uma UTINEO, durante 1 ano. O consumo de antimicrobianos/antibióticos foi medido em dias de terapia/1000pacientes-dia (DOT/1000PD) Resultados e conclusões: Entre setembro de 2017 e setembro de 2018, admitimos 308 pacientes, a maioria com peso>1500g (303/308-98,4%), totalizando 2223 pacientes-dia. Oito IRAS foram registradas, correspondendo a uma taxa de 2,6% (ou densidade de incidência de 3,6/1000PD). Em cinco das oito infecções (62,5%), um agente infeccioso foi isolado, sendo três bactérias Gram-negativas (todas Klebsiella pneumoniae, 2 com perfil de produção de beta-lactamase de espectro estendido) e duas infecções por Candida sp. Não houve infecção por BGN-CR. O consumo total de antimicrobianos em DOT/1000PD foi de 1638 e o de carbapenêmicos 49,3; o que representou 3% do total, com tendência de queda durante o ano. Em setembro de 2017, implementamos um programa de gestão de antimicrobianos (PGA), em adição às medidas de controle de infecção realizadas desde 2005. Os elementos-chave do PGA foram: auditoria de antibióticos e feedback, restrição de antimicrobianos-alvo e maior rapidez na liberação de resultados de culturas. Verificamos adequado controle de BGN-CR, não sendo encontrada infecção por este agente, tendência de queda no consumo de antimicrobianos e carbapenêmicos

Antimicrobial consumption in pediatric intensive care units during the first year of COVID-19 pandemic / Consumo antimicrobiano em unidades de cuidados intensivos pediátricos durante o primeiro ano da pandemia de COVID-19

Introduction: The absence of standardized treatment for critical children admitted in pediatric intensive care units (PICUs) with COVID could lead to an increase in antimicrobial consumption, as indirect effect. Aim: To describe trends of antimicrobial consumption in two PICUs before and during the COVID pandemic year.Methods: We did a retrospective study in children admitted in two PICUs of Rio de Janeiro city, between March 2019 and March 2021. The first year represented the pre-pandemic period and the last one the pandemic period. Trends of antimicrobial consumption were measured by days of therapy (DOT/1000 patient-days) and analyzed by linear regression for antibiotics, antivirals and antifungals Results: Number of patients-days in the PICU 1 was 3495 in the pre-pandemic period and 3600 in the pandemic period. The overall DOT/1000 PD of antibiotics, antivirals and antifungal was 15,308.1, 942.8 and 1,691.1, respectively in the pre-pandemic period and 13,481.5, 1,335.4 and 1,243.7, respectively in pandemic period. It was verified trend of reduction of antibiotic and antifungals and increase in antivirals consumption. Number of patients-days in the PICU 2 was 5029 in the pre-pandemic period and 4557 in the pandemic period and the overall DOT/1000 PD of antibiotics, antivirals and antifungal was 16,668.5, 1,385 and 1,966.7, respectively in the pre-pandemic period and 10,896.5, 830.7 and 677.3 in pandemic period. It was verified trend of reduction of antibiotic, antivirals and antifungals consumption. Conclusion: Trends of antimicrobial consumption reduction were verified for antibiotics and antifungals in two PICUs and reduction for antiviral in one of them

Respirometry and Ruminant Nutrition

The gaseous exchange between an organism and the environment is measured by respirometry or indirect calorimetry. Once the oxygen consumption (O2) and the production of carbon dioxide (CO2) and methane (CH4) are known, the energy losses by gas and heat can be calculated. Energy metabolism and methane production have been studied in the Calorimetry and Metabolism Laboratory of the Federal University of Minas Gerais, located in Belo Horizonte, Minas Gerais, Brazil. Animals used are mainly Zebu cattle and their crossbreeds that represent most beef and dairy cattle breed grazed on tropical pastures. System calibration and routine work are addressed in this text. The results obtained on respirometric chambers are expressed in net energy (NE), which can be net energy for maintenance (NEm), lactation (NEL), weight gain (NEg), and pregnancy (NEp). NE is, in fact, what is used by the animal for maintenance and each productive function. The values of k (conversion efficiency of ME into NE) for maintenance (km), milk (kL), weight gain or growth (kg), and pregnancy (kp) are determined. Thanks to the peculiarity of the respirometric technique, the same animal can be evaluated several times, in different physiological states and planes of nutrition

The Impact of Interventions to Prevent Neonatal Healthcare-associated Infections in Low- and Middle-income Countries: A Systematic Review.

BACKGROUND: Clinically suspected and laboratory-confirmed bloodstream infections are frequent causes of morbidity and mortality during neonatal care. The most effective infection prevention and control interventions for neonates in low- and middle-income countries (LMIC) are unknown. AIM: To identify effective interventions in the prevention of hospital-acquired bloodstream infections in LMIC neonatal units. METHODS: Medline, PUBMED, the Cochrane Database of Systematic Reviews, EMBASE and PsychInfo (January 2003 to October 2020) were searched to identify studies reporting single or bundled interventions for prevention of bloodstream infections in LMIC neonatal units. RESULTS: Our initial search identified 5206 articles; following application of filters, 27 publications met the inclusion and Integrated Quality Criteria for the Review of Multiple Study Designs assessment criteria and were summarized in the final analysis. No studies were carried out in low-income countries, only 1 in Sub-Saharan Africa and just 2 in multiple countries. Of the 18 single-intervention studies, most targeted skin (n = 4) and gastrointestinal mucosal integrity (n = 5). Whereas emollient therapy and lactoferrin achieved significant reductions in proven neonatal infection, glutamine and mixed probiotics showed no benefit. Chlorhexidine gluconate for cord care and kangaroo mother care reduced infection in individual single-center studies. Of the 9 studies evaluating bundles, most focused on prevention of device-associated infections and achieved significant reductions in catheter- and ventilator-associated infections. CONCLUSIONS: There is a limited evidence base for the effectiveness of infection prevention and control interventions in LMIC neonatal units; bundled interventions targeting device-associated infections were most effective. More multisite studies with robust study designs are needed to inform infection prevention and control intervention strategies in low-resource neonatal units

Microcephaly epidemic related to the Zika virus and living conditions in Recife, Northeast Brazil.

BACKGROUND: Starting in August 2015, there was an increase in the number of cases of neonatal microcephaly in Northeast Brazil. These findings were identified as being an epidemic of microcephaly related to Zika virus (ZIKV) infection. The present study aims to analyse the spatial distribution of microcephaly cases in Recife (2015-2016), which is in Northeast Brazil, and its association with the living conditions in this city. METHODS: This was an ecological study that used data from reported cases of microcephaly from the State Health Department of Pernambuco (August 2015 to July 2016). The basic spatial unit of analysis was the 94 districts of Recife. The case definition of microcephaly was: neonates with a head circumference of less than the cut-off point of -2 standard deviations below the mean value from the established Fenton growth curve. As an indicator of the living conditions of the 94 districts, the percentage of heads of households with an income of less than twice the minimum wage was calculated. The districts were classified into four homogeneous strata using the K-means clustering algorithm. We plotted the locations of each microcephaly case over a layer of living conditions. RESULTS: During the study period, 347 microcephaly cases were reported, of which 142 (40.9%) fulfilled the definition of a microcephaly case. Stratification of the 94 districts resulted in the identification of four strata. The highest stratum in relation to the living conditions presented the lowest prevalence rate of microcephaly, and the overall difference between this rate and the rates of the other strata was statistically significant. The results of the Kruskal-Wallis test demonstrated that there was a strong association between a higher prevalence of microcephaly and poor living conditions. After the first 6 months of the study period, there were no microcephaly cases recorded within the population living in the richest socio-economic strata. CONCLUSION: This study showed that those residing in areas with precarious living conditions had a higher prevalence of microcephaly compared with populations with better living conditions

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
