In the present work, three series of cinnamic (1), p-coumaric (2) and ferulic (3) esters containing different side-chains such as ethyl (1a-3a), n-propyl (1b-3b), n-butyl (1c-3c), n-pentyl (1d-3d), n-hexyl (1e-3e), and n-heptyl (1f-3f) were prepared, tested for activity against trypomastigote forms of the parasite Trypanosoma cruzi and toxicity against NCTC cells. Obtained results indicated that the presence of p-coumaric or ferulic moieties associated with C4-C7 linear side-chains play an important role in the bioactivity against T. cruzi since compounds 2c-2f and 3d-3f were found to be the most active derivatives with a half maximal effective concentration (EC50) value ranging from 12.8 to 1.7 μM, superior to that determined for the positive control benznidazole (EC50 = 16.4 μM). Additionally, machine learning and multivariate statistical analyses identified molecular features correlated with biological activity, emphasizing the importance of side-chain length and lipophilicity, highlighting the significance of the molecular structure of phenylpropanoid derivatives in the activity against T. cruzi. work 1, 1 , (1) pcoumaric p coumaric 2 (2 3 (3 sidechains side chains 1a3a, 1a3a aa 1a 3a (1a-3a) npropyl n propyl 1b3b, 1b3b bb 1b 3b b (1b-3b) nbutyl butyl 1c3c, 1c3c cc 1c 3c c (1c-3c) npentyl pentyl 1d3d, 1d3d dd 1d 3d d (1d-3d) nhexyl hexyl 1e3e, 1e3e ee 1e 3e e (1e-3e) nheptyl heptyl 1f3f ff 1f 3f f (1f-3f prepared cells C4C7 CC C4 C7 C C4-C T 2c2f cf 2c 2f 3d3f df EC50 EC 128 12 8 12. 17 7 1. μM (EC5 164 16 4 16. μM. . μM) Additionally sidechain chain lipophilicity (1 ( (1a-3a (1b-3b (1c-3c (1d-3d (1e-3e C4C EC5 (EC

With the increase in industrial production, there is a direct increase in waste generation. Milk processing industries are one of these cases that results in a complex effluent with a high organic load. If the effluent is discarded without proper treatment, it can compromise the survival of biota in water courses. Advanced oxidation processes (AOP) are one of the main technologies used in the treatment of effluents, especially the Photocatalysis-Self-Fenton System (PF) type. The present study aimed to evaluate the efficiency of the PF process and to optimize the parameters of dairy effluent treatment. The raw effluent was characterized considering the parameters: conductivity, pH, chemical oxygen demand (COD), solids, and oils and greases. Through an experimental design, the variation of the concentrations of Fe2+, H2O2 and the reaction time were optimized, and the influence of these three variables on the removal of COD was evaluated. Statistical analysis showed that all variables were statistically significant, and the model used had a coefficient of determination of 0.97, confirming that the model was well adjusted. The ideal conditions for COD removal, reaching 79%, were obtained in 60 min, 0.625 g L-1 of Fe2+ and 0.829 mL L-1 of H2O2. production generation load courses AOP (AOP effluents PhotocatalysisSelfFenton Photocatalysis Self Fenton (PF type conductivity pH COD, , (COD) solids greases design Fe2 Fe HO H O H2O optimized evaluated significant 097 0 97 0.97 adjusted 79 79% 6 min 0625 625 0.62 L1 L 1 L- 0829 829 0.82 (COD 09 9 0.9 7 062 62 0.6 082 82 0.8 0. 06 08 8

ABSTRACT The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.

Resumo Antecedentes Embora existam várias formas de estimar a dor na demência ainda há necessidade de ferramentas com melhores itens para avaliação da presença e intensidade da dor nesses indivíduos. Objetivo Analisar as propriedades psicométricas de uma ferramenta de avaliação da dor em idosos dementados, a “Pain Intensity Measure for Persons with Dementia Portuguese - PIMD-p”. Métodos Idosos expostos a situações potencialmente dolorosas, sendo esses dementados e com prejuízo na comunicação verbal, foram selecionados em uma unidade ambulatorial e uma instituição de longa permanência, em São Paulo. A PIMD-p foi aplicada por 2 pesquisadores (E1 e E2), de forma separada, num mesmo dia, e, com intervalo de no máximo 14 dias, essa foi reaplicada por apenas um deles (E3), e ainda, foi obtida a intensidade álgica inferida pelos cuidadores dos idosos participantes. Na análise estatística foram utilizados o Alfa de Cronbach, o Coeficiente de Spearman e o Índice de Correlação Intraclasses. Resultados Selecionada uma amostra de 50 idosos com média de idade de 86 anos, a maioria portadora de demência moderada e de dor de origem musculoesquelética. Apuradas para a PIMD-p uma boa consistência interna, segundo o alfa Cronbach (0,838); excelentes reprodutibilidades intra e interobservador (0,927 e 0,970, respectivamente; p < 0,001); e uma validade convergente, essa última obtida com as fortes e significativas correlações entre as intensidades dolorosas inferidas e os indicadores de dor do instrumento em estudo (exceto para o indicador “olhar expressivo”; corr = 0,106 e p = 0,462).

Abstract Background Although there are several ways to assess pain in dementia, there is still a need for tools with better items to assess the presence of pain intensity in these individuals. Objective To validate to Brazilian version of the “Pain Intensity Measure for Persons with Dementia – PIMD-p. Methods Older adults, all demented with impaired verbal communication and exposed to potentially painful situations, were selected from an outpatient clinic and long-term care facility (LTCF). The PIMD-p was applied independently by 2 researchers (E1 and E2) on the same day. Within 14 days, the instrument was reapplied by one of the 2 researchers (E3). The pain intensity reported by participants' caregivers and LTCF nurses were recorded on a verbal numeric pain scale. For the statistical analysis, Cronbach's Alpha, Spearman's Coefficient and intraclass correlation Index were calculated. Results A total of 50 older individuals were selected (mean age 86 years), majority with musculoskeletal pain. The PIMD-p demonstrated good internal consistency according to Cronbach's α (0.838), excellent intra and interobserver reproducibility (0.927 and 0.970, respectively; p < 0.001), and convergent validity (strong significant correlations between reported pain intensities and pain indicators on the PIMD-p (except for expressive eyes; corr = 0.106 and p = 0.462). A ROC curve was plotted to determine the best cut-off for the PIMD-P, and a score of 7.5 predicted moderate-to-severe pain, with 77.8% sensitivity and 95.7% specificity (p < 0.001). Conclusion The PIMD-p showed satisfactory psychometric properties for measuring intensity of pain in demented older adults with impaired verbal communication. dementia Pain PIMDp.

Abstract The Santos Basin (SB) is the main petroliferous basin in the Brazilian continental margin and one of the most studied marine areas in Brazil. However, historical data suggest that new efforts should be carried out to acquire quantitative biological data, especially in the deep sea, to establish the baseline of essential ocean variables in different ecosystems for future monitoring programs. The Brazilian energy company Petrobras planned and executed 24 oceanographic cruises over a period of 2 years to assess the benthic (SANSED cruise) and pelagic (SANAGU cruise) systems of the SB (356 days at sea in 2019 and 2021/2022). These efforts were part of the Santos Project, which comprised a comprehensive environmental study aimed at investigating benthic and pelagic variables to characterize ecology, biogeochemistry, thermohaline properties of water masses, and ocean circulation patterns, geomorphology, and sedimentology, as well as organic and inorganic chemistry. Here we present the detailed sampling designs and the field methods employed on board, during the SB scientific cruises. All sampling protocols were based on standardized approaches. For the benthos analyses, triplicate sediment samples were performed using a GOMEX-type box corer (0.25 m²) or a large modified Van Veen grab (0.75 m²) at 100 stations ranging from 25 to 2400 m depth. At each station, 25 geochemical and physico-chemical parameters were analyzed in addition to micro-, meio-, and macrofauna and living foraminifera samples. For the pelagic system, 60 stations were selected to investigate the plankton community, ranging in size from pico- to macroplankton, through vertical, horizontal, and oblique net hauls (20, 200, and 500 μm mesh size), as well as 25 biogeochemical parameters collected with an aid of a CTD-rosette sampler. Part of this scientific information also serves the Regional Environmental Characterization Project (PCR-BS) in support of Petrobras’ Santos Basin drilling licensing process led by the Brazilian Environmental Agency – IBAMA. This project contributes to the sustainable development of the SB, in line with the guidelines of the United Nations Decade of Ocean Science for Sustainable Development.

RESUMO OBJETIVO Realizar uma análise econômica de custo da implementação de um programa de rastreio de colo curto para redução da prematuridade em gestações únicas num horizonte temporal de curto prazo. MÉTODOS Realizamos uma análise econômica do tipo custo-benefício utilizando o banco de dados do P5 trial, um ensaio clínico multicêntrico randomizado para prevenção da prematuridade. A coleta de dados ocorreu de julho de 2015 a março de 2019 em 17 diferentes hospitais do Brasil. Comparamos os custos do rastreamento universal em mulheres com gestação única de 18 a 22 semanas e 6 dias associado à progesterona vaginal profilática 200 mg/dia até 36 semanas naquelas com colo ≤ 25 mm com os do não rastreamento. O horizonte temporal foi do nascimento até 10 semanas após o parto. O desfecho foi medido monetariamente em real brasileiro (R$) na perspectiva do Sistema Único de Saúde. RESULTADOS Entre 7.844 mulheres, 6,67% (523) apresentaram colo ≤ 25mm. O custo do rastreio com a ultrassonografia transvaginal mais a progesterona vaginal para prevenção de nascimentos < 34 semanas foi estimado em R$ 383.711,36, enquanto o não rastreamento gerou custo adicional estimado de R$ 446.501,69 (relacionado aos 29 partos prematuros não rastreados). Assim, o rastreamento mais a profilaxia geraria uma redução de custo final de R$ 62.790,33, apresentando-se como uma possível estratégia de custo-benefício. CONCLUSÃO O rastreamento universal de colo curto para prematuridade apresenta menores custos em relação ao não rastreamento dentro de um horizonte temporal de curto prazo, o que sugere uma interessante relação de custo versus benefício. Novos estudos que considerem a custo-efetividade do tratamento profilático utilizando-se de análises de sensibilidade em diferentes cenários dentro do sistema de saúde brasileiro, assim como análises que considerem os custos de longo prazo atrelados ao nascimento prematuro, são necessários para justificar com robustez a implementação de um programa de rastreamento. custobenefício benefício P trial 201 1 Brasil 2 20 mgdia mg dia 3 parto R (R$ Saúde 7844 7 844 7.84 667 67 6,67 523 (523 25mm 38371136 383 711 383.711,36 44650169 446 501 69 446.501,6 relacionado rastreados. rastreados . rastreados) Assim 6279033 62 790 33 62.790,33 apresentandose apresentando se custobenefício. custoefetividade efetividade utilizandose prematuro (R 784 84 7.8 66 6,6 52 (52 3837113 38 71 383.711,3 4465016 44 50 446.501, 627903 79 62.790,3 78 8 7. 6, 5 (5 383711 383.711, 446501 4 446.501 62790 62.790, ( 38371 383.711 44650 446.50 6279 62.790 3837 383.71 4465 446.5 627 62.79 383.7 446. 62.7 383. 62.
ABSTRACT OBJECTIVE To perform an economic cost analysis of the implementation of a short cervix screening program to reduce preterm birth in singleton pregnancies in a short-term time horizon. METHODS We performed a cost-benefit economic analysis using the P5 trial database, a randomized multicenter clinical trial for prevention of preterm birth. Data collection was conducted from July 2015 to March 2019 in 17 different Brazilian hospitals. We conducted a cost analysis for universal cervical screening in singleton pregnancies between 18 weeks and 22 weeks plus 6 days. In subjects with a cervical length ≤ 25 mm, the analysis incorporated the costs of administering 200 mg/day of vaginal progesterone prophylactically until 36 weeks gestation. These findings were subsequently compared with the economic implications of forgoing cervical screening. The time horizon comprised from birth to 10 weeks postpartum. The outcome was measured monetarily in Brazilian real (R$) from the perspective of the Unified Health System. RESULTS Among 7,844 women, 6.67% (523) had a cervix ≤ 25 mm. The cost of screening with transvaginal ultrasound and vaginal progesterone for prevention of births with < 34 weeks was estimated at R$ 383,711.36, while non-screening generated an estimated additional cost of R$ 446,501.69 (related to the 29 non-screened preterm deliveries). Thus, screening and prophylaxis would generate a final cost reduction of R$ 62,790.33, constituting a possible cost-benefit strategy. CONCLUSION Universal short cervix screening for preterm birth has lower costs compared to non-screening within a short-term time horizon, which suggests an interesting benefit-cost ratio. Future studies should consider the cost-effectiveness of prophylactic treatment using sensitivity analyses in different scenarios within the Brazilian health system, as well as analyses that consider the long-term costs associated with preterm births, to robustly justify the implementation of a short cervix screening program. shortterm term costbenefit benefit P database 201 1 hospitals 2 days mm 20 mgday mg day 3 gestation postpartum R (R$ System 7844 7 844 7,84 women 667 67 6.67 523 (523 38371136 383 711 383,711.36 nonscreening non 44650169 446 501 69 446,501.6 related nonscreened screened deliveries. deliveries . deliveries) Thus 6279033 62 790 33 62,790.33 strategy benefitcost ratio costeffectiveness effectiveness system longterm long (R 784 84 7,8 66 6.6 52 (52 3837113 38 71 383,711.3 4465016 44 50 446,501. 627903 79 62,790.3 78 8 7, 6. 5 (5 383711 383,711. 446501 4 446,501 62790 62,790.

ABSTRACT Water supply quality, nutrient availability in irrigation solutions, and discharge water or effluents must be monitored for protected cultivation to achieve sustainable management of food production. This study aimed to evaluate whether effluent solution from mini-tomato-protected crops can be recycled in an irrigation system based on plant nutritional demands. The experiment was carried out on a farm with mini-tomato protected-cropping. Water supply, as well as nutrient and effluent solutions, were analyzed in the experiment. Water supply was within the Brazilian limits established by CONAMA, except for nitrite, phosphorus, and sulfide. The effluent solution showed significant concentrations of macro- and micronutrients, highlighting phosphorus (220 to 395 mg L-1). The replacement of nutrient solution in the central fertigation tank, excess of elements applied in the nutrient solution, and accumulation of effluent solution in the disposal tank kept the effluent solution enriched when compared to the nutrient solution initially applied. Water quality monitoring showed that effluent solution can be reused in the irrigation system based on its physicochemical parameters and mini-tomato tomato nutritional demands. The analyses also allowed us to detect control points to achieve food production sustainability.

Abstract Staphylococcus aureus is one of the main pathogens associated with foodborne outbreaks in Brazil and food handlers can carry toxigenic and resistant S. aureus strains. The aims of this study were to verify the frequency of virulence genes, to identify the agr groups and to determine the antimicrobial resistance profile of S. aureus strains isolated from food handlers of pilot kitchens located in São Paulo, Brazil. A total of 74 strains of the Staphylococcus genus were detected and 50% were identified as of the species S. aureus. The enterotoxin genes detection, tst and luk-PV detection, agr typing, mecA detection, ccr complex detection and SCCmec typing were performed using PCR. The antimicrobial resistance testing was performed by the disk diffusion method. The enterotoxin genes were identified in 36 S. aureus, including sea (83.8%). The tst gene was detected in 18.92% of the strains and the luk-PV was detected in only one isolate. Agr typing classified 58.3% of the strains as type I. Seven (18.92%) strains were classified as MRSA and the ccr2 complex was detected in six of these isolates. The SCCmec typing characterized strains as type II, III, IV and V. Moreover, there were also a greater number of resistant strains to penicillin (83.78%) and clarithromycin (67.57%). In conclusion, the study revealed a significant prevalence of S. aureus, and the presence of different virulence genes and a worrying resistance profile in S. aureus strains isolated from food handlers in this country.

OBJECTIVES: To prospectively evaluate demographic, anthropometric and health-related quality of life (HRQoL) in pediatric patients with laboratory-confirmed coronavirus disease 2019 (COVID-19) METHODS: This was a longitudinal observational study of surviving pediatric post-COVID-19 patients (n=53) and pediatric subjects without laboratory-confirmed COVID-19 included as controls (n=52) was performed. RESULTS: The median duration between COVID-19 diagnosis (n=53) and follow-up was 4.4 months (0.8-10.7). Twenty-three of 53 (43%) patients reported at least one persistent symptom at the longitudinal follow-up visit and 12/53 (23%) had long COVID-19, with at least one symptom lasting for >12 weeks. The most frequently reported symptoms at the longitudinal follow-up visit were headache (19%), severe recurrent headache (9%), tiredness (9%), dyspnea (8%), and concentration difficulty (4%). At the longitudinal follow-up visit, the frequencies of anemia (11% versus 0%, p=0.030), lymphopenia (42% versus 18%, p=0.020), C-reactive protein level of >30 mg/L (35% versus 0%, p=0.0001), and D-dimer level of >1000 ng/mL (43% versus 6%, p=0.0004) significantly reduced compared with baseline values. Chest X-ray abnormalities (11% versus 2%, p=0.178) and cardiac alterations on echocardiogram (33% versus 22%, p=0.462) were similar at both visits. Comparison of characteristic data between patients with COVID-19 at the longitudinal follow-up visit and controls showed similar age (p=0.962), proportion of male sex (p=0.907), ethnicity (p=0.566), family minimum monthly wage (p=0.664), body mass index (p=0.601), and pediatric pre-existing chronic conditions (p=1.000). The Pediatric Quality of Live Inventory 4.0 scores, median physical score (69 [0-100] versus 81 [34-100], p=0.012), and school score (60 [15-100] versus 70 [15-95], p=0.028) were significantly lower in pediatric patients with COVID-19 at the longitudinal follow-up visit than in controls. CONCLUSIONS: Pediatric patients with COVID-19 showed a longitudinal impact on HRQoL parameters, particularly in physical/school domains, reinforcing the need for a prospective multidisciplinary approach for these patients. These data highlight the importance of closer monitoring of children and adolescents by the clinical team after COVID-19.

OBJECTIVES: We designed a cohort study to describe characteristics and outcomes of patients with coronavirus disease (COVID-19) admitted to the intensive care unit (ICU) in the largest public hospital in Sao Paulo, Brazil, as Latin America becomes the epicenter of the pandemic. METHODS: This is the protocol for a study being conducted at an academic hospital in Brazil with 300 adult ICU beds dedicated to COVID-19 patients. We will include adult patients admitted to the ICU with suspected or confirmed COVID-19 during the study period. The main outcome is ICU survival at 28 days. Data will be collected prospectively and retrospectively by trained investigators from the hospital’s electronic medical records, using an electronic data capture tool. We will collect data on demographics, comorbidities, severity of disease, and laboratorial test results at admission. Information on the need for advanced life support and ventilator parameters will be collected during ICU stay. Patients will be followed up for 28 days in the ICU and 60 days in the hospital. We will plot Kaplan-Meier curves to estimate ICU and hospital survival and perform survival analysis using the Cox proportional hazards model to identify the main risk factors for mortality. ClinicalTrials.gov: NCT04378582. RESULTS: We expect to include a large sample of patients with COVID-19 admitted to the ICU and to be able to provide data on admission characteristics, use of advanced life support, ICU survival at 28 days, and hospital survival at 60 days. CONCLUSIONS: This study will provide epidemiological data about critically ill patients with COVID-19 in Brazil, which could inform health policy and resource allocation in low- and middle-income countries.

This work describes, for the first time, the preparation of palladium nanoparticles supported in thermally-treated human hair. Human hair showed to be an efficient adsorbent of Pd2+ in aqueous media, reaching nearly 100% of adsorption from a 100 ppm solution. The thermal treatment of hair containing Pd2+ at 200 ºC under nitrogen atmosphere led to the formation of an N, S-containing material presenting 0.5 wt.% of palladium. The material was extensively characterized by elemental analysis (CHN and inductively coupled plasma optical emission spectroscopy (ICP OES)), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FTIR) and Raman spectroscopies, and by thermogravimetry (TG), thermogravimetry coupled to mass spectrometry (TG-MS), scanning electron miscroscopy (SEM), transmission electron microscopy (TEM) and dispersive X-ray spectroscopy (EDS) analyses. It was possible to observe that the surface structure of hair was preserved during thermal treatment, presenting palladium nanoparticles with particle sizes of approximately 4 nm. This material was used as heterogeneous catalyst in a preliminary application in nitrobenzene reduction to aniline in aqueous medium using sodium borohydride.

Seriniquinone is a natural quinone isolated from a rare marine bacterium of the genus Serinicoccus. This secondary metabolite has been shown to have anticancer properties, which has raised attention of the scientific community. In this short report, we present the first investigation of the gas-phase chemistry fragmentation reactions of seriniquinone in electrospray ionization tandem mass spectrometry (ESI-MS/MS), to be further applied in pharmacokinetics and metabolism studies. All the proposals herein were supported by computational chemistry.

Abstract AIMS To analyze if different resistance training (machine vs free weight) would have different acute hypotensive effect in active and normotensive individuals. METHODS Fifteen male volunteers (39.2±2.5 years) performed two different resistance exercise protocols, one on machinery and one with free weights for the similar muscle groups and volume (sets x repetitions). Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured at rest and during 60 minutes after the sessions. RESULTS There was no interaction between (treatments vs time) for SBP (F 70, 84 = 0.9445, p = 0.595) and DBP (F 70, 84 = 0.5743, p = 0.991). However, significant differences for time for SBP (F 14, 84 = 7.058, p = 0.001) and DBP (F 14, 84 = 3.296, p = 0.001), and treatment for SBP (F 5, 6 = 291.1, p = 0.001) and DBP (F 5, 6 = 13.29, p = 0.003) were varified. CONCLUSION Our findings indicate that both resistance training (machine or free weight) induce a similar hypotensive response for SBP in normotensive men.

RESUMO Introdução: Os principais patógenos causadores de infecções nosocomiais foram resumidos pela sigla ESKAPE, que são as iniciais das seguintes bactérias: Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumanni, Pseudomonas aeruginosa e Enterobacter spp., as quais possuem altas taxas de resistência por conseguirem escapar das ações dos antimicrobianos. Objetivo: Traçar o perfil de suscetibilidade antimicrobiana do grupo ESKAPE em um hospital primário da rede pública do Distrito Federal, Brasil. Métodos: Foi realizado um estudo transversal, retrospectivo e descritivo, analisando os dados correspondentes de janeiro de 2010 a dezembro de 2015 para as amostras consideradas positivas para o grupo ESKAPE, com o intuito de gerar um perfil de sensibilidade aos antimicrobianos. Resultados: Ao analisar bactérias Gram positivas, quase 80% das cepas de Enterococcus faecium foram resistentes à vancomicina (VRE) e cerca de 40% das cepas de Staphylococcus aureus, resistentes à oxacilina (MRSA). Nas bactérias do grupo ESKAPE, observaram-se cepas com uma taxa de resistência maior aos carbapenens do que em outros estudos. Ao realizar uma análise molecular, quatro cepas de Klebsiella pneumoniae foram positivas para o gene blaKPC e três, para o blaNDM; uma de Acinetobacter baumanni foi positiva para o gene blaOXA-23. Conclusão: Estudos como este devem ser realizados periodicamente de modo a avaliar o perfil de suscetibilidade das bactérias. Eles demonstram a importância do uso de estratégias para evitar infecções nosocomiais, bem como um maior controle na prescrição de antimicrobianos.
ABSTRACT Introduction: The leading cause of hospital-acquired infections are the pathogens named by the acronym ESKAPE, which are the initials for the following bacterial: Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumanni, Pseudomonas aeruginosa and Enterobacter spp., which have high resistance rates by escaping the action of the antimicrobial. Objective: To trace the antimicrobial susceptibility profile of the ESKAPE pathogens in a primary public hospital in the Federal District, Brazil. Methods: A cross-sectional, retrospective and descriptive study was conducted by analyzing the corresponding data from January 2010 to December 2015 of samples considered positive to ESKAPE pathogens in order to generate an antimicrobial susceptibility profile. Results: Analyzing the Gram-positive bacteria, almost 80% of E. faecium strains were vancomycin-resistant enterococci (VRE) and almost 40% of S. aureus strains were methicillin (oxacillin)-resistant Staphylococcus aureus (MRSA). It was observed that gram-negative strains (the ESKAPE group) examined in this study have a higher resistance rate to carbapenems than in other studies. In the molecular analysis, four Klebsiella pneumoniae strains were positive to blaKPC gene, three strains to blaNDM and one Acinetobacter baumanni strain was positive to blaOXA-23 gene. Conclusion: Studies such as this should be performed periodically in order to evaluate the bacterial susceptibility profile. They demonstrate the importance of implementing strategies to prevent hospital-acquired infections, as well as greater antibiotic prescribing control.
