The impact of COVID-19 on microbiological profile and antibiotic consumption in ICU: a retrospective study in an infectious disease hospital in Brazil

Abstract Background The COVID-19 pandemic has triggered crises in the public health sector that have complex and multifaceted interrelationships with antimicrobial resistance. It is important to evaluate the impact of COVID-19 on microbiological profile, antibiotic and alcohol gel consumption in Intensive Care Units (ICU). Methods This is a retrospective study undertaken in an infectious disease hospital located in Bahia/Brazil during three periods: from March 2019 to February 2020; from March 2020 to February 2021; and from March 2021 to February 2022. It was evaluated the incidence density of Candida spp and of multidrug-resistant Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species (ESKAPE group) in blood, urine and tracheal secretion isolated 48 h after the patient's admission to the ICU, as well as the use of alcohol gel (in milliliters) and consumption of antibiotics in Defined Daily Dose (DDD) per 1,000 ICU patient-days in the previous year and in the first two years of COVID-19 pandemic. Results There was an increase in Candida spp. (5.81, p < 0.001, IRR = 10.47, 95 % CI 2.57‒42.62) and in carbapenem-resistant A. baumannii in clinical cultures (4.71, p < 0.001, IRR = 8.46, 95 % CI 2.07‒34.60), the latter mainly in tracheal secretions (3.18, p =0.02, IRR = 11.47, 95 % CI 1.58‒83.39). A rise in the consumption of ceftriaxone and piperacillin-tazobactam, along with an increase in the utilization of alcohol gel were observed. Conclusion The shifting microbiological profile can be attributed to both the unique characteristics of patients with COVID-19 and the adjustments made to healthcare facilities' structural and work routines. Understanding these changes is essential in addressing the accelerated impact of antimicrobial resistance during the pandemic. Therefore, conducting thorough reviews of institutional practices and routines becomes critical in mitigating the consequences of antimicrobial resistance and its implications for patient care.

Longitudinal bond strength of a universal adhesive and chemical dentin characterization under different acid etching protocols

Abstract Objective This study aimed to analyze the longitudinal bond strength of a universal adhesive and chemically characterize the dentin substrate under different acid etching protocols. Methodology Dentin samples were etched with polyacrylic acid 25% (PAA) for 10 seconds (n=3) and phosphoric acid 32% (PA) for 15 seconds (n=3) and analyzed by Fourier transform infrared spectroscopy - attenuated total reflectance (FTIR-ATR) before and after treatment. For collagen degradation, samples (n=12) were divided into 3 groups: PAA, PA, and Deionized water (control), and analyzed by the quantity of solubilized type I collagen C-terminal cross-linked telopeptides and solubilized C-terminal peptide in relation to total protein concentration (ICTPtp and CTXtp) and by their ultimate tensile strength (UTS). For the adhesive interface analysis, dentin samples (n=72) were divided into 3 groups: PAA, PA, and Self-etch (SE), and subdivided into 2 groups: 24 h (baseline) and 1 year. The following tests were performed: microtensile bond strength (μTBS) (n=48), scanning electron microscopy (SEM) (n=12), and nanoleakage (n=12). Results The FTIR of PAA showed lower reduction of the peaks in the phosphate group when compared to PA. For ICTPtp, PA showed a significantly higher value. For CTXtp, PA and PAA groups failed to statically differ from each other. UTS was significantly lower for PA. For μTBS, storage time significantly affected bond strength. The results were unaffected by the etching protocol. For SEM, after 1 year, PA had little evidence of degradation in the upper third of the adhesive interface in comparison to the other groups. Nanoleakage showed no considerable silver impregnation after 1 year in the SE group. Conclusion The use of PAA prior to a universal adhesive (when compared to PA) represents a less aggressive type of etching to dentin. However, self-etching still seems to be the best option for universal adhesive systems that have functional monomers in their composition.

Establecimiento del esquema de purificación de los antígenos de SOBERANA®02, SOBERANA®Plus y SOBERANA 01 / Establishment of the purification scheme for SOBERANA®02, SOBERANA®Plus and SOBERANA 01 antigens

La urgente necesidad de desarrollar y producir vacunas seguras y efectivas para garantizar la reducción de la propagación del coronavirus de tipo 2 causante del síndrome respiratorio agudo severo, hizo que el Centro de Inmunología Molecular y el Instituto Finlay de Vacunas, desarrollaran dos vacunas y un candidato vacunal contra la COVID-19, que tienen como componente la molécula del dominio de unión al receptor (aa 319-541) del virus. Para establecer el proceso productivo, se realizaron experimentos en los posibles pasos del proceso de purificación de la molécula del dominio de unión al receptor (aa 319-541), con vistas a su posterior transferencia tecnológica a escala industrial. Dicha molécula está fusionada con una etiqueta de hexahistidina en su extremo C-terminal y presenta nueve residuos de cisteína en su secuencia que forman cuatro enlaces disulfuros intramoleculares, quedando una cisteína libre que permite obtener dos moléculas: dimérica y monomérica, antígenos que forman parte de las vacunas SOBERANA®02 y SOBERANA®Plus y el candidato vacunal SOBERANA 01. Se determinaron las mejores condiciones de adsorción de las matrices cromatográficas de afinidad por quelatos metálicos, intercambio catiónico y exclusión molecular. Se evaluó el desempeño del proceso a escala piloto y se caracterizó la molécula de acuerdo a sus propiedades físico-químicas y biológicas. Los resultados obtenidos mostraron un 60,02 ± 5,15por ciento de recuperación total de la proteína de interés, con más del 98% de pureza en ambas moléculas, una eficiente remoción de contaminantes y una antigenicidad mayor del 90por ciento referido al monómero control del dominio de unión al receptor con 99 por ciento de pureza, lo que demuestra que el proceso establecido es eficiente en la obtención de un producto con la calidad requerida(AU)

The urgent need to develop and produce safe and effective vaccines to guarantee the reduction of the spread of the type 2 coronavirus that causes severe acute respiratory syndrome, led the Center for Molecular Immunology and the Finlay Vaccine Institute to develop two vaccines and one candidate vaccine to combat the 2019 coronavirus pandemic. As part of the establishment of the production process, experiments were carried out on the possible steps of the purification process of the receptor binding domain molecule (aa 319-541) with a view to its subsequent technological transfer on an industrial scale. This molecule is fused with a hexahistidine tag at its C-terminal end and has nine cysteine residues in its sequence that form four intramolecular disulfide bonds; leaving a free cysteine that allows two molecules to be obtained: dimeric and monomeric, which constitute the antigens of the SOBERANA®02 and SOBERANA®Plus vaccines and the SOBERANA 01 vaccine candidate. The best adsorption conditions of the chromatographic matrices of affinity for metal chelates, cationic exchange and molecular exclusion were determined. The performance of the process was evaluated on a pilot scale and the molecule was characterized according to its physical-chemical and biological properties. The results obtained showed a 60.02 ± 5.15percent total recovery of the protein of interest with more than 98% purity in both molecules, an efficient removal of contaminants and an antigenicity greater than 90percent referred to the control monomer of the domain receptor binding with 99% purity; which demonstrates that the established process is efficient in obtaining a product with the required quality(AU)

Electrocardiographic Findings Among Asymptomatic Adults With Haemophilia

Abstract Background: People with haemophilia (PwH) are living longer. Therefore, they can develop atherosclerotic cardiovascular disease (ASCVD). Electrocardiogram (ECG) alterations may be a sign of initial ASCVD before the occurrence of symptoms. Objective: To describe the prevalence of resting ECG alterations among PwH adults asymptomatic for ASCVD. Methods: PwH aged ≥ 30 years without previous ASCVD events were considered for the analysis. Resting ECG traces were analysed according to international reference values and the Brazilian Longitudinal Adult Health Study (ELSA-Brasil) results for asymptomatic Brazilian men. Based on the established normal values and using the QT index, we further described the altered ECGs as minor or major changes, according to the Minnesota Code. Differences between prevalences were evaluated by Pearson's χ2 test. Differences between medians were evaluated by the Mann-Whitney U test. A p-value < 0.05 was accepted as statistically significant. Results: A total of 64 PwH were included in the study. Median age was 44 years (interquartile range 35-52). Most patients had haemophilia A (81%) and 47% were severe. The prevalence of obesity, systemic arterial hypertension (SAH), diabetes mellitus (DM), and dyslipidaemia were 16%, 56%, 14%, and 72%, respectively. All the PwH had sinus rhythm, except for one, who had an implanted pacemaker due to idiopathic third-degree atrioventricular block. Altered ECGs were found in 25% and 30% of PwH, according to established criteria and ELSA-Brasil criteria, respectively. Major changes were found in eight (13%) PwH according to the Minnesota Code, including two ECGs with ischaemia-like wall inactivity. Conclusions: The prevalence of altered ECG varied from 25% to 30% among asymptomatic PwH.

As medidas de interação foram verificadas com base no critério da aditividade, pelo cálculo do excesso de prevalência, excesso de razão de prevalência e diferença relativa. Resultados: participaram 3.343 trabalhadores, 77,9% do sexo feminino. A prevalência de TMC foi 21,7% maior entre mulheres, negros e pessoas em situações de exposição aos estressores laborais. Entre as mulheres negras em situação de DER, a prevalência de TMC foi três vezes maior em relação aos homens brancos em situação de equilíbrio (grupo de referência). Discussão: trabalhadoras negras acumulam desvantagens sociais e estão mais suscetíveis a ocupações de maior esforço e menor recompensa. A prevalência de TMC foi superior na intersecção das exposições. O efeito combinado dos fatores excedeu a soma dos efeitos isolados, demonstrando interação entre gênero, raça e estressores ocupacionais.

Abstract Objective: analyze the isolated and combined effects of gender, race, and occupational stressors on the mental health of healthcare workers. Methods: cross-sectional study with a random sample of health workers in Bahia, Brazil. The primary exposure variables were gender, race, and occupational stressors, assessed using the Effort-Reward Imbalance (ERI) scale. The Self-Reporting Questionnaire (SRQ-20) measured common mental disorders (CMD), the outcome variable. The interaction measures were verified based on the additivity criterion by calculating the excess prevalence, excess prevalence ratio, and relative difference. Results: 3,343 workers participated, 77.9% were female. CMD prevalence was 21.7% higher among women, Black people, and those exposed to work stressors. Among Black women in a situation of ERI, the prevalence of CMD was three times higher compared with white men in a situation of balance (reference group). Discussion: black women workers accumulate social disadvantages and are more susceptible to occupations that require more significant effort and less reward. CMD prevalence was higher at the intersection of exposures. Combined effect of the factors exceeded the sum of the isolated effects, demonstrating an interaction between gender, race, and occupational stressors.

Comparison between the ion-specific electrode and SPADNS methods for analysis of fluoride concentration in the water supply

The maintenance of adequate fluoride (F) concentration in the public water supply is fundamental for ensuring that the community use of F can reach the maximum benefit for caries control and minimum risk for dental fluorosis. Thus, surveillance systems must use accurate and valid analytical methods to determine F concentration and, according to the literature, give preference to the ion-specific electrode (F- ISE) analysis. Aim: The objective of this study was to compare the accuracy of the ISE and SPADNS methods in the determination of the F concentration in the same water sample. Methods: Duplicate water samples were taken from 30 sampling sites in the municipality of Maringá, state of Paraná, monthly for 12 months, totaling 276 samples. An aliquot was analyzed by the FOP-UNICAMP Oral Biochemistry laboratory, using the F- ISE method, and the other one, by the SANEPAR laboratory in Maringá/PR, using the SPADNS method. Descriptive analysis and Pearson's correlation test were applied, with a significant level of p<0.05. Results: Results were expressed as ppm F (mg F/L), and a very strong positive correlation (r= 0.91; p<0.001) was detected between the two methods of analysis. Conclusion: Our findings suggest that the determination of f luoride concentration in water can be made with accuracy by the SPADNS method, a standardized analysis protocol

Evaluación de la disfunción del endotelio para el pronóstico de riesgo cardiovascular / Evaluation of endothelial dysfunction for cardiovascular risk prediction i: en

Introducción: Las enfermedades cardiovasculares constituyen la primera causa de muerte en el mundo, por lo que la identificación y modificación de los factores de riesgo asociados a ellas constituyen estrategias priorizadas por la Organización Mundial de la Salud. Contar con un modelo de predicción del riesgo cardiovascular enriquecido con la evaluación de la disfunción endotelial influiría positivamente en estas metas. Objetivos: Identificar la presencia de disfunción endotelial en pacientes con enfermedades cardiovasculares o sin estas y determinar la asociación entre ambas. Métodos: Se realizó un estudio observacional y descriptivo, de serie de casos, en el Centro de Cardiología y Cirugía Cardiovascular del Hospital Provincial Docente Clínico-Quirúrgico Saturnino Lora de Santiago de Cuba, desde enero del 2022 hasta igual mes del 2023, donde se analizaron como variables los factores de riesgo cardiovascular tradicionales y los biomarcadores de disfunción endotelial. Secundariamente, se llevó a cabo un estudio analítico de casos y controles en el cual se aplicó la regresión logística binaria multivariada. Resultados: Se confirmó la presencia de disfunción endotelial asociada a la aparición de las enfermedades cardiovasculares, lo que se evaluó a través del índice de vasodilatación, mediado por el flujo de la arteria braquial y las concentraciones plasmáticas de fibrinógeno. Conclusiones: Las características epidemiológicas y clínicas de los pacientes con enfermedades cardiovasculares o sin estas no difirieron de lo registrado en la literatura especializada acerca de la base de identificación de los factores de riesgo tradicionales.

Introduction: Cardiovascular diseases constitute the first death cause worldwide, reason why the identification and modification of associated risk factors constitute prioritized strategies by the World Health Organization. To have a prediction model of cardiovascular risk enriched with the evaluation of the endothelial dysfunction would influence positively in these goals. Objectives: To identify the presence of endothelial dysfunction in patients with or without cardiovascular diseases and to determine the association between them. Methods: An observational and descriptive cases series study was carried out in the Cardiology and Cardiovascular Surgery Center at Saturnino Lora Teaching Clinical Surgical Provincial Hospital in Santiago de Cuba, from January, 2022 to the same month, 2023, where the traditional cardiovascular risk factors and endothelial dysfunction biomarkers were analyzed as variables. Secondarily, an analytic case-control study was carried out in which multivariate binary logistic regression was applied. Results: The presence of endothelial dysfunction associated with the onset of cardiovascular diseases was confirmed, what was evaluated through the vasodilatation index, mediated by the brachial artery flow and the fibrinogen plasmatic concentrations. Conclusions: The clinical and epidemiological pattern of patients with or without cardiovascular diseases did not differ from that reported in the specialized literature on the base of the identification of traditional risk factors.

Estimación de factores de riesgo del retardo en la cicatrización en pacientes quemados / Estimation of Risk Factors for Delayed Healing in Burn Patients

Introducción: La atención al paciente con retardo en la cicatrización parte de la optimización en sus cuidados. La reversión del cuadro requiere del conocimiento de los factores de riesgo. La literatura nacional e internacional describen factores locales o relacionados con la herida y generales o relacionados al estado general del paciente. Objetivo: Estimar los factores de riesgo del retardo en la cicatrización en pacientes quemados. Métodos: Estudio analítico de casos y control en pacientes quemados ingresados en el Servicio de Caumatología del Hospital Universitario Manuel Ascunce Domenech en el período 2017 a 2021. La población objeto de estudio comprendió a 267 pacientes. Se calculó el odds ratio y el intervalo de confianza. Resultados: El desarrollo de retardo en la cicatrización resultó tres veces y media más probable en pacientes quemados con 45 años y más, odds ratio 3,591. Además, fue nueve veces más probable en enfermedades crónicas asociadas, hasta seis veces en quemaduras no accidentales, 163 veces en la complicación local y 89 veces en la complicación sistémica. Conclusiones: Los factores de riesgo del retardo en la cicatrización en pacientes quemados identificados fueron los siguientes: edad de 45 años y más, presencia de comorbilidad, el fuego directo como agente causal, el modo de producción no accidental, la presencia de más de seis zonas anatómicas afectadas, la quemadura hipodérmica, la quemadura de 20 porciento de superficie corporal quemada y más de extensión, el apoyo de la lesión, el índice cubano de pronóstico con riesgo vital, la complicación local y la complicación sistémica(AU)

Introduction: The care for the patient with delayed healing starts from the optimization of their care. Reversing such condition requires knowledge of the risk factors. The national and international literature describes local factors related to the injury and general factors related to the patient's general condition. Objective: To estimate the risk factors for delayed healing in burn patients. Methods: An analytical case-control study was carried out with burn patients admitted to the caumatology service at Hospital Universitario Manuel Ascunce Domenech in the period from 2017 to 2021. The study population consisted of 267 patients. Odds ratio and confidence interval were calculated. Results: The development of delayed healing was three and a half times more likely in burn patients aged 45 years or over (odds ratio: 3.591). In addition, it was nine times more likely for associated chronic diseases, up to six times in nonaccidental burns, 163 times in local complications, and 89 times in systemic complications. Conclusions: The identified risk factors for delayed healing in burn patients were the following: age 45 years or over, presence of comorbidity, direct fire as causative agent, nonaccidental way of production, presence of more than six affected anatomical areas, hypodermic burn, burn extension of 20 percent or over on the burned body surface, injury contact pressure, the Cuban index of prognostic vital risk, as well as the local or the systemic complications(AU)
