Resumo Introdução: Monitorar a qualidade da água nos serviços de diálise móvel (DM), avaliando os pontos críticos e caracterizando os riscos inerentes ao processo, é fundamental para evitar riscos à saúde do paciente. Este estudo avaliou a qualidade microbiológica da água na DM de 36 hospitais com tratamento intensivo no município do Rio de Janeiro. Métodos: Foram coletadas 204 amostras de água dos pontos de entrada da rede (REDE), pós-osmose (PO) e solução de diálise (SD). As amostras foram avaliadas quanto à contagem de bactérias heterotróficas, pesquisa de patógenos, presença de endotoxinas e teor de alumínio. Resultados: A contaminação bacteriana, em 3 pontos de coleta nos 36 hospitais, foi de 30% (32/108), sendo 42% provenientes da SD, 31% da PO e 17% da REDE, com presença de Pseudomonas aeruginosa, Stenotrophomonas maltophilia, Burkholderia cepacia e Ralstonia pickettii nos 3 pontos. Concentrações de endotoxina acima de 0,25 EU/mL ocorreram em 77% das amostras (17/22) analisadas na PO. No teor de alumínio, os valores acima de 0,01 mg/L foram apresentados em 47% (7/15) das amostras da PO e 27% (4/15) das amostras da REDE. Não existe uma legislação específica para água utilizada na DM; logo, foram utilizados os limites da RDC da Agência Nacional de Vigilância Sanitária (Anvisa) 11/2014, que regulamenta os serviços de hemodiálise convencional. Conclusão: Os resultados ressaltam a importância da avaliação da qualidade da água nos serviços de DM para garantir a segurança do paciente e subsidiar o monitoramento sanitário desse processo como um promotor de saúde.

Abstract Introduction: Monitoring water quality in mobile dialysis (MD) services, assessing critical points and characterizing the risks inherent in the process, is essential to avoid risks to the patient's health. This study evaluated the microbiological quality of water in the MD of 36 hospitals with intensive treatment in the city of Rio de Janeiro. Methods: 204 water samples were collected from the points of entry to the network (NET), post-osmosis (PO) and dialysis solution (DS). The samples were evaluated for heterotrophic bacteria count, pathogen search, presence of endotoxins and aluminum content. Results: Bacterial contamination at 3 collection points in 36 hospitals was 30% (32/108); 42% from DS, 31% from PO and 17% from NET, with the presence of Pseudomonas aeruginosa, Stenotrophomonas maltophilia , Burkholderia cepacia and Ralstonia pickettii in the 3 points. Endotoxin concentrations above 0.25 EU/mL occurred in 77% of the samples (17/22) analyzed in the PO. In the aluminum content, values above 0.01 mg/L were presented in 47% (7/15) of PO samples and 27% (4/15) of NET samples. There is no specific legislation for water used in the MD; therefore, the limits of the RDC of the National Health Surveillance Agency (Anvisa) 11/2014 were used; which regulates conventional hemodialysis services. Conclusion: The results highlight the importance of evaluating water quality in MD services to ensure patient safety and support the sanitary monitoring of this process as a healthcare promoter.

Resumen: En | Texto: En | PDF: En

Abstract This study aimed to develop an acerola smoothie using gellan gum (GG) as a texture modifier. Samples were developed with three concentrations of GG (0.1%, 0.2%, 0.3% w/v) and a control sample (without GG). Physicochemical, rheological, and sensory properties were evaluated. The smoothie samples showed increased color intensity than the control, with a tendency to yellow and red colors. However, the hydrocolloid concentration did not affect the samples' pH values (4.13 to 4.17). GG presence favored an increase in the samples' viscosity, classified as pseudoplastic fluid. There was a reduction in vitamin C in samples with GG (422.18 to 430.49 mg/100 g), however, the values remained close to the control (448.89 mg/100 g). There was greater sensory acceptance by the sample with intermediate texture (0.2% GG), which obtained a higher frequency for the attributes "homogeneous" and "acerola flavor".

Resumen: En | Texto: En | PDF: En

OBJECTIVE: Coronavirus disease 2019 (COVID-19) is associated with high mortality among hospitalized patients and incurs high costs. Severe acute respiratory syndrome coronavirus 2 infection can trigger both inflammatory and thrombotic processes, and these complications can lead to a poorer prognosis. This study aimed to evaluate the association and temporal trends of D-dimer and C-reactive protein (CRP) levels with the incidence of venous thromboembolism (VTE), hospital mortality, and costs among inpatients with COVID-19. METHODS: Data were extracted from electronic patient records and laboratory databases. Crude and adjusted associations for age, sex, number of comorbidities, Sequential Organ Failure Assessment score at admission, and D-dimer or CRP logistic regression models were used to evaluate associations. RESULTS: Between March and June 2020, COVID-19 was documented in 3,254 inpatients. The D-dimer level ≥4,000 ng/mL fibrinogen equivalent unit (FEU) mortality odds ratio (OR) was 4.48 (adjusted OR: 1.97). The CRP level ≥220 mg/dL OR for death was 7.73 (adjusted OR: 3.93). The D-dimer level ≥4,000 ng/mL FEU VTE OR was 3.96 (adjusted OR: 3.26). The CRP level ≥220 mg/dL OR for VTE was 2.71 (adjusted OR: 1.92). All these analyses were statistically significant (p<0.001). Stratified hospital costs demonstrated a dose-response pattern. Adjusted D-dimer and CRP levels were associated with higher mortality and doubled hospital costs. In the first week, elevated D-dimer levels predicted VTE occurrence and systemic inflammatory harm, while CRP was a hospital mortality predictor. CONCLUSION: D-dimer and CRP levels were associated with higher hospital mortality and a higher incidence of VTE. D-dimer was more strongly associated with VTE, although its discriminative ability was poor, while CRP was a stronger predictor of hospital mortality. Their use outside the usual indications should not be modified and should be discouraged.

RESUMO Objetivo: Avaliar a concordância entre médicos intensivistas que receberam treinamento semelhante para utilização do ultrassom pulmonar à beira do leito, na identificação das linhas B pulmonares visualizadas em tempo real, a fim de verificar a reprodutibilidade do método. Métodos: Foram analisados 67 pacientes que apresentaram alguma piora ventilatória identificada nas últimas 12 horas da realização do ultrassom pulmonar, no período de novembro de 2016 a março de 2017, estando todos internados em um centro de terapia intensiva de um hospital privado de Belo Horizonte (MG). Os ultrassons pulmonares foram realizados por três profissionais diferentes, denominados A, B e C, sendo o intervalo de tempo entre cada ultrassom pulmonar menor que 3 horas. As zonas torácicas visualizadas foram apenas as anteriores e laterais, sendo definidas como zonas anteriores (1) direita e esquerda (Z1D e Z1E, respectivamente), delimitadas pela clavícula, esterno, linha horizontal perpendicular ao processo xifoide e linha axilar anterior; e zonas laterais (2) direita e esquerda (Z2D e Z2E, respectivamente), abrangendo a área entre linha axilar anterior e posterior lateralmente, tendo como limite inferior a mesma linha horizontal correspondente à altura do processo xifoide. Uma zona pulmonar era considerada positiva para linhas B, quando houvesse visualização de três ou mais dessas linhas, caracterizando possível síndrome interstício-alveolar. Por meio do valor Kappa, avaliamos a concordância dentre as quatro zonas, conforme execução de cada dupla de profissional (AB, AC e BC). Resultados: Cerca de 80% das áreas visualizadas tiveram concordância classificada como moderada a substancial, com Kappa variando de 0,41 - 079 (p < 0,05; IC95%). Os maiores graus de concordância ocorreram nas zonas superiores Z1D e Z1E entre os subgrupos AC e BC, com Kappa em torno de 0,65 (p < 0,001). Já a Z2E apresentou uma das menores concordâncias, com Kappa de 0,36. Conclusão: A possível limitação do ultrassom pulmonar quanto ao efeito examinador-dependente não se mostrou presente neste trabalho, sugerindo boa reprodutibilidade dessa modalidade diagnóstica à beira do leito.

ABSTRACT Objective: To evaluate the agreement between intensive care physicians with similar training in the use of bedside lung ultrasonography in identifying pulmonary B lines, visualized in real time, to verify the reproducibility of the method. Methods: A total of 67 patients with some ventilatory deterioration identified within 12 hours after a pulmonary ultrasonography in the period from November 2016 to March 2017 were analyzed, and all were admitted to an intensive care unit of a private hospital in Belo Horizonte, Minas Gerais. The lung ultrasonographies were performed by three different professionals, termed A, B and C, and the time interval between each lung ultrasonography was less than 3 hours. The only visualized chest zones were the anterior and lateral, defined as right and left anterior (1) zones (Z1R and Z1L, respectively), which were delimited by the clavicle, the sternum and the horizontal line perpendicular to the xiphoid process and anterior axillary line. The right and left lateral (2) zones (Z2R and Z2L, respectively) covered the lateral area between the anterior and posterior axillary lines, with the lower limit being the same horizontal line corresponding to the height of the xiphoid process. A lung zone was considered positive for B lines upon visualization of three or more of these lines, suggesting the presence of alveolar-interstitial syndrome. Using the Kappa value, we evaluated the agreement among the four zones according to the execution of each pair of professionals (AB, AC and BC). Results: Approximately 80% of the areas that were visualized showed a moderate to substantial agreement, with the Kappa values ranging from 0.41 - 079 (p < 0.05; 95% CI). The highest levels of agreement occurred in the upper zones Z1R and Z1L between subgroups AC and BC, with a Kappa of approximately 0.65 (p < 0.001). In turn, Z2L showed one of the lowest agreements, with a Kappa of 0.36. Conclusion: The possible limitation of an examiner-dependent effect on lung ultrasounds was not found in this study, suggesting the good reproducibility of this diagnostic modality at the bedside.

RESUMO OBJETIVO Analisar o impacto das condições hospitalares adquiridas em mulheres no ciclo gravídico puerperal no tempo de permanência. MÉTODOS Este estudo transversal foi conduzido com 113.456 mulheres, entre julho de 2012 e julho de 2017, em hospitais nacionais da rede suplementar de saúde e filantrópicos credenciados para atendimento pelo Sistema Único de Saúde (SUS). Os dados das altas hospitalares foram coletados utilizando o sistema Diagnosis-Related Groups (DRG Brasil®). Foram incluídos todos os DRG que compõem a grande categoria diagnóstica 14 (MDC14), abrangendo gestação, parto e puerpério. O impacto das condições hospitalares adquiridas no tempo de permanência foi estimado por meio do teste t de Student, e o tamanho do efeito pelo d de Cohen, que permite avaliar a relevância clínica. RESULTADOS As categorias diagnósticas relacionadas à MDC14 mais prevalentes foram partos vaginais sem diagnósticos complicadores e cesáreas, tanto nas instituições credenciadas para atendimento pelo SUS quanto nas de saúde suplementar. A prevalência de condições hospitalares adquiridas foi de 3,8% na saúde suplementar e 2,5% no SUS. Observou-se maior tempo de permanência nos hospitais que prestam serviços a operadoras da saúde suplementar do Brasil na presença de CHA para as pacientes categorizadas nos DRG: cesariana com complicações ou comorbidades presentes à admissão (p < 0,001; d de Cohen = 0,74), cesariana sem complicações ou comorbidades presentes à admissão (p < 0,001; d de Cohen = 0,31), doenças puerperais e pós-aborto sem cirurgia (p < 0,001; d de Cohen = 1,05) e outras doenças da gravidez com complicações clínicas (p < 0,001; d de Cohen = 0,77). CONCLUSÕES O presente estudo revelou que a prevalência de condições adquiridas foi baixa tanto nas instituições credenciadas para atendimento pelo SUS quanto nas de saúde suplementar; entretanto, sua presença contribui para o aumento do tempo de permanência hospitalar em casos de cesáreas sem complicações ou comorbidades nas instituições de saúde suplementar.

ABSTRACT OBJECTIVE To analyze the impact of the Hospital-Acquired Conditions (HAC) in women in the puerperal and pregnancy cycle during length of stay. METHODS This cross-sectional study was conducted with 113,456 women, between July 2012 and July 2017, in Brazil’s national hospitals of the supplementary healthcare networks and philanthropists accredited to the Unified Health System (SUS). Data on hospital discharges were collected using the Diagnosis-Related Groups (DRG Brasil®) system. All DRGs of the major diagnostic category 14 (MDC14), including pregnancy, childbirth and puerperium, were included. The impact of HAC on length of stay was estimated by Student’s t-test, and the effect size by Cohen’s d, which allows to assess clinical relevance. RESULTS The most prevalent diagnostic categories related to MDC14 were vaginal and cesarean deliveries without complicating diagnoses, both at institutions accredited to SUS and those for supplementary health care. The prevalence of HAC was 3.8% in supplementary health and 2.5% in SUS. Hospitals providing services to supplementary health care providers had a longer length of stay considering HAC for patients classified as DRG: cesarean section with complications or comorbidities at admission (p < 0.001; Cohen’s d = 0.74), cesarean section without complications or comorbidities at admission (p < 0.001, Cohen’s d = 0.31), postpartum and post abortion without listed procedure (p < 0.001, Cohen’s d = 1.05), and other antepartum diagnoses with medical complications (p < 0.001; Cohen’s d = 0.77). CONCLUSIONS This study showed that the prevalence of HAC was low both in the institutions accredited to attend by SUS and in those of supplementary health; however, its presence contributes to increasing the length of stay in cases of cesarean sections without complications or comorbidities in supplementary health institutions.

Resumen: En | Texto: En | PDF: En

Abstract Tucupi is a fermented liquid obtained from cassava (Manihot esculenta Crantz), very much appreciated by the traditional cuisine of Northern Brazil. However, there are no scientific reports on its use in the formulation of products. Thus, the present study aimed to elaborate a powdered condiment with tucupi, as well as to assess the product’s sensory acceptability and its hygroscopic behavior. The powdered tucupi used in the formulation of the condiment was obtained by drying in a spray dryer. The product underwent sensory evaluation for its acceptability regarding the attributes of color, aroma, flavor, and overall impression and a purchase intention test was applied by hedonic scale. The acceptability index was 80% for overall impression and the purchase intention test indicated that 94% of the judges would be willing to buy the product. The product’s moisture sorption isotherms presented type-II behavior for adsorption and type-III for desorption, at 25 °C. The hygroscopic behavior indicated that the product is more susceptible to spoilage changes when stored in an environment with relative humidity above 60% and the Peleg model showed an excellent performance on predicting the product’s moisture sorption isotherms.

Abstract Tucupi, a fermented product obtained from cassava (Manihot esculenta Crantz) is widely employed in the cuisine of the Northern region of Brazil, however, its industrial application is incipient. This study used tucupi to prepare a creamy paste, which underwent sensory and rheological evaluation. Paste formulations with 5 to 20% concentrated tucupi were obtained. An acceptance test was used to assess the product’s acceptability regarding the attributes of color, aroma, flavor, texture, and overall impression. A purchase intention test of the product was also applied. The product’s rheology was studied at 25, 40, and 60 °C and the activation energy (Ea) was estimated. The internal preference mapping indicated that the paste formulation with 5% and 10% tucupi were the most accepted by the judge, but only the 10% tucupi paste was characterized. Proportions greater than 15% tucupi influenced negatively in the flavor and texture of the product. Purchase intention test showed that 99% of the judges demonstrated interest in purchasing the product. The product presented 72.7% moisture, 10.4% lipids, 0.5% proteins, 2.1% ashes, 14.3% carbohydrates, and 7.4 μg/g β-carotene. According to the rheological assays, the paste presented characteristics of a pseudoplastic fluid. The Herschel-Bulkley model proved efficient to predict the flow curves for the product in the temperature range tested, for which Ea was estimated at 7.49 kJ/mol.

Resumen: En | Texto: En | PDF: En

Carbapenem-resistance mechanisms are a challenge in the treatment of Pseudomonas aeruginosa infections. We investigated changes in P. aeruginosa carbapenem-resistance determinants over a time period of eight years after the emergence of São Paulo metallo-β-lactamase in a university hospital in Rio de Janeiro, Brazil. Patients admitted to the intensive care unit (ICU) were screened for P. aeruginosa colonisation and followed for the occurrence of infections from April 2007 to April 2008. The ICU environment was also sampled. Isolates were typed using random amplified polymorphic DNA, pulsed-field gel electrophoresis and multilocus sequence typing. Antimicrobial susceptibility was determined by disk diffusion and E-test, production of carbapenemases by a modified-CarbaNP test and presence of carbapenemase-encoding genes by polymerase chain reaction. Non-carbapenemase resistance mechanisms studied included efflux and AmpC overexpression by PAβN and cloxacillin susceptibility enhancement, respectively, as well as oprD mutations. From 472 P. aeruginosa clinical isolates (93 patients) and 17 isolates from the ICU environment, high genotypic diversity and several international clones were observed; one environment isolate belonged to the blaSPM-1 P. aeruginosa epidemic genotype. Among isolates from infections, 10 (29%) were carbapenem resistant: none produced carbapenemases, three exhibited all non-carbapenemase mechanisms studied, six presented a combination of two mechanisms, and one exclusively displayed oprD mutations. Carbapenem-resistant P. aeruginosa displayed a polyclonal profile after the SPM-1 epidemic genotype declined. This phenomenon is connected with blaSPM-1 P. aeruginosa replaced by other carbapenem-resistant pathogens.

Os anti-helmínticos empregados no tratamento das helmintoses intestinais, de modo geral, são eficazes, porém nas parasitoses teciduais, como é o caso da toxocaríase visceral, a eficácia é moderada. Este estudo teve como objetivo avaliar in vitro a atividade do lapachol, β-lapachona e fenazinas derivadas da β-lapachona sobre a viabilidade de larvas de Toxocara canis. Os compostos foram testados na concentração de 2 mg/mL (em duplicata) em placas de microcultivo, contendo larvas de T. canis em meio RPMI-1640, sendo incubados, a 37 °C, em tensão de CO2 de 5%, por 48 horas. Na concentração de 2 mg/mL, quatro fenazinas, o lapachol e três derivados, apresentaram atividade larvicida/larvostática de 100%. A seguir, foi realizado o teste de concentração larvicida/larvostártica mínima (CLM). Os compostos que apresentaram os melhores resultados foram o nor-lapachol (CLM, 1 mg/mL), lapachol (CLM, 0,5 mg/mL), a β-lapachona e a β-C-alil-lausona (CLM, 0,25 mg/mL). As larvas expostas aos compostos, na melhor CLM 100% in vitro foram inoculadas em camundongos BALB/c saudáveis não sendo capazes de causar infecção, confirmando o potencial larvicida in vitro desses compostos.

Anthelmintics used for intestinal helminthiasis treatment are generally effective; however, their effectiveness in tissue parasitosis (i.e. visceral toxocariasis) is moderate. The aim of this study was to evaluate the in vitroactivity of lapachol, β-lapachone and phenazines in relation to the viability of Toxocara canis larvae. A concentration of 2 mg/mL (in duplicate) of the compounds was tested using microculture plates containing Toxocara canis larvae in an RPMI-1640 environment, incubated at 37 °C in 5% CO2 tension for 48 hours. In the 2 mg/mL concentration, four phenazines, lapachol and three of its derivatives presented a larvicide/larvistatic activity of 100%. Then, the minimum larvicide/larvistatic concentration (MLC) test was conducted. The compounds that presented the best results were nor-lapachol (MLC, 1 mg/mL), lapachol (MLC 0.5 mg/mL), β-lapachone, and β-C-allyl-lawsone (MLC, 0.25 mg/mL). The larvae exposed to the compounds, at best MLC with 100% in vitro activity larvicide, were inoculated into healthy BALB/c mice and were not capable of causing infection, confirming the larvicide potential in vitro of these compounds.

Objetivo: Analisar a influência dos componentes da síndrome metabólica na resistência à insulina, por sexo e fase da adolescência. Sujeitos e métodos: Avaliaram-se dados bioquímicos, clínico, de estilo de vida e composição corporal de 800 adolescentes de 10 a 19 anos, de ambos os sexos, de Viçosa-MG/Brasil, divididos em fases: inicial (10 a 13 anos), intermediária (14 a 16 anos) e final (17 a 19 anos). Resultados: 10,3 e 3,4% apresentavam, respectivamente, resistência à insulina e síndrome metabólica. Na fase inicial, observaram-se maior prevalência de dislipidemia e na intermediária, de hiperuricemia e excesso de gordura corporal. O sexo feminino apresentou maior prevalência de dislipidemia, excesso de gordura corporal e resistência à insulina e o masculino, maior prevalência de HDL baixo, hiperuricemia e pressão arterial alterada. Os da fase inicial apresentaram maiores valores de colesterol total, LDL, HDL, triglicerídeos, glicemia de jejum e relação cintura/quadril, ficaram menos tempo sentados e realizavam maior número de refeições (p < 0,05) em relação às outras fases. O modelo final, ajustado por sexo, foi diferente para cada fase da adolescência. Conclusões: A resistência à insulina está associada à inadequação na composição corporal, nos níveis bioquímicos e no estilo de vida, sendo os fatores associados diferentes em cada fase da adolescência. Arq Bras Endocrinol Metab. 2014;58(6):610-8

Objective: To analyze the influence of metabolic syndrome components in insulin resistance, by gender and adolescence phase. Subjects and methods: We evaluated biochemical, clinical, lifestyle and body composition data of 800 adolescents from 10 to 19 years old, from both genders, from Viçosa, MG/Brasil, and there was the division by stage: early (10 to 13 years), intermediate (14 to 16 years) and late (17 to 19 years). Results: 10.3 and 3.4% had, respectively, insulin resistance and metabolic syndrome. In the initial phase there was a higher prevalence of dyslipidemia and intermediate hyperuricemia and excess body fat. Females had a higher prevalence of dyslipidemia, excess body fat and insulin resistance and higher male prevalence of low HDL, hyperuricemia and blood pressure changes. Those from the initial phase had higher levels of total cholesterol, LDL, HDL, triglycerides, fasting glucose and waist/hip ratio, stayed less time sitting and had more meals (p < 0.05) in relation to other phases. The final model, adjusted for gender, was different for each phase of adolescence. Conclusions: Insulin resistance is associated with inadequate body composition, in biochemical levels and lifestyle, being the factors associated different in each phase of adolescence.

Resumen: Pt En | Texto: Pt En | PDF: Pt | PDF: En

A Caderneta de Saúde da Criança (CSC) é um documento imprescindível para a promoção da saúde infantil. Foi realizado um estudo transversal com amostra aleatória simples de crianças acompanhadas no Sistema Único de Saúde (SUS), visando analisar os fatores associados à qualidade do preenchimento da CSC. Foram realizadas entrevistas e verificação direta das cadernetas de 365 crianças das nove regionais de saúde de Belo Horizonte, Minas Gerais, Brasil. Foi criado um sistema de escore para classificar as CSC quanto à qualidade do seu preenchimento e relacioná-la às variáveis explicativas. O odds ratio foi calculado por regressão logística. O preenchimento dos vinte itens do escore variou de 3,1% (uso de ferruginoso) a 99,7% (data de nascimento). Os fatores associados aos piores escores foram: crianças > 12 meses de idade (OR = 1,77), mães < 6 anos de estudo (OR = 1,97), crianças não acompanhadas por médicos generalistas (OR = 3,18) e mães que não receberam explicações sobre a CSC na maternidade (OR = 1,77). Os resultados apontam a precária utilização da CSC, reforçando a necessidade de investimentos em capacitação dos profissionais e organização dos serviços para que ela cumpra seu papel na promoção da saúde infantil.

The Child Health Record (CHR) is an essential document for children's health care activities. A cross-sectional study was performed with simple random sampling, aimed at analyzing factors related to quality of data completion on the CHR. Interviews and direct verification of 365 CHRs from 9 health districts in Belo Horizonte, Minas Gerais State, Brazil, were performed. A scoring system was created to classify the CHRs in terms of quality of data completion and to relate them to explanatory variables. Odds ratios were calculated by logistic regression. Completion of the 20 scoring items varied from 3.1% (use of iron supplements) to 99.7% (date of birth). Factors associated with worse scores were: children > 12 months old (OR = 1.77), mothers with < 6 years of schooling (OR = 1.97), children not treated by general practitioners (OR = 3.18), and mothers who had not received explanations on the CHR while in the maternity ward (OR = 1.77). The results show poor use of the CHR and emphasize the need for on-going efforts to train health professionals and prepare health services for their important role in the promotion of children's health.
