Impact of COVID-19 on healthcare-associated infections: Antimicrobial consumption does not follow antimicrobial resistance.

BACKGROUND: This study aimed to analyze the Healthcare-Associated Infections (HAI) rates and antimicrobial consumption in Intensive Care Units (ICU) in São Paulo city during the COVID-19 pandemic and compare them with the pre-pandemic period. METHODS: This cohort included all hospitals that reported HAI rates (Central-Line-Associated Bloodstream Infection ‒ CLABSI and Ventilator-Associated Pneumonia ‒ VAP), the proportion of microorganisms that caused CLABSI, the proportion of resistant microorganisms, and antimicrobial consumption from January 2017 ‒ December 2020. Hospitals were stratified by the number of beds, Central Venous Catheter (CVC) utilization rate, Mechanical-Ventilation (MV) utilization rate, and type of funding. Statistical analyses were based on time-series plots and regression models. RESULTS: 220 ICUs were included. The authors observed an abrupt increase in CLABSI rates after the pandemic onset. High CLABSI rates during the pandemic were associated with hospital size, funding (public and non-profit private), and low CVC use (≤ 50%). An increase in VAP rates was associated with public hospitals, and high MV use (> 35%). The susceptibility profile of microorganisms did not differ from that of the pre-pandemic period. polymyxin, glycopeptides, and antifungal use increased, especially in COVID-19 ICUs. CONCLUSIONS: HAI increased during COVID-19. The microorganisms' susceptibility profile did not change with the pandemic, but the authors observed a disproportionate increase in large-spectrum antimicrobial drug use.

Clinical study of complications of a peripherally inserted central catheter in cancer patients.

AIM: To evaluate complications after PICC use in cancer patients. DESIGN: This was a clinical and retrospective study in which the risk factors and complications of PICC use were evaluated. METHODS: This study was carried out in the patient, emergency room, and intensive care units through the evaluation of electronic medical records. To assess the association between qualitative variables, the chi-squared test or Fisher's exact test was used, and to compare the reason for withdrawal, the Kruskal-Wallis test was applied. RESULTS: A total of 359 patients (53.5% men) with 43.1 ± 14 years who had a PICC (88% with solid tumours) were evaluated. The most common complications were mechanical complications (61.2%), infection (38%), and thrombosis (57.1%). Patients with double-lumen catheters experienced thrombosis (85.7%). This study demonstrated the effectiveness of PICC and that patients with haematological cancer are more prone to multiple PICC passages and more mechanical complications and infections.

Flushing na manutenção de cateteres intravenosos: um estudo observacional da prática de enfermagem na terapia intensiva / Flushing in the maintenance of intravenous catheters: an observational study of nursing practice in intensive care

A manutenção da permeabilidade do cateter intravenoso usado em pacientes hospitalizados é essencial para prevenir danos e garantir a segurança da terapia intravenosa. Dentre os cuidados de enfermagem preconizados para essa manutenção está o flushing, que é a aplicação de solução salina no lúmen do cateter com o objetivo de limpeza. Essa pesquisa teve como objetivos: Caracterizar a prática da equipe de enfermagem na realização do flushing para a manutenção de cateteres intravenosos utilizados por pacientes hospitalizados em cenários de cuidados intensivos; Avaliar a associação de características profissionais da equipe de enfermagem com a prática do flushing na manutenção de cateteres intravenosos em pacientes hospitalizados em cenários de cuidados intensivos; Analisar a prática do flushing em relação às melhores evidências para a manutenção dos cateteres intravenosos, na perspectiva da segurança do paciente; Elaborar, à luz dessa análise, uma tecnologia de cuidado voltada a promover as boas práticas de enfermagem na realização do flushing para a manutenção dos cateteres intravenosos. Estudo observacional, transversal e com abordagem quantitativa, realizado em quatro cenários de cuidados intensivos de um hospital universitário do município do Rio de Janeiro. Participaram 108 profissionais de enfermagem que realizavam a manutenção dos dispositivos intravenosos e estavam envolvidos na prática do flushing. Os dados foram coletados através de observação por meio checklist e aplicação de questionário estruturado, no período de novembro de 2019 a janeiro de 2020. A análise ocorreu por meio de estatística descritiva, analítica e inferencial. Foram realizadas 404 observações da prática do flushing, das quais em 23% não houve a realização do flushing e, em 77%, a prática do flushing foi realizada em algum momento da manipulação do dispositivo intravenoso. Das observações em que houve algum momento de flushing, em 52% os profissionais utilizaram frasco de grande volume no preparo; 97% utilizaram solução fisiológica; 70% aplicaram a técnica de pressão contínua no êmbolo da seringa; 64,5% não avaliaram previamente a permeabilidade. Houve predomínio da prática do flushing após a administração de medicamentos, com emprego do volume e seringa de 10 ml. Possuir formação específica ligada a acesso venoso, conhecimento de guidelines e tempo de exercício profissional inferior a cinco anos foram variáveis que aumentaram as chances de realização do flushing na prática. Quanto aos dados do questionário: 88% dos participantes responderam que efetuam o procedimento do flushing na sua prática; 93% descreveram o soro fisiológico como a solução de escolha; 49,5% relataram realizar o flushing com a pressão contínua no êmbolo da seringa, enquanto 35% aplicam a técnica push pause. No que tange à frequência, apenas 22% referiram que realizam o flushing antes, entre e após a administração de um medicamento. Entretanto, quando essa frequência foi graduada numa escala, nos dados do cateter venoso central, principal dispositivo manipulado na prática, 64% referiram que realizam muitas vezes/sempre o flushing antes da administração do medicamento, 68% realizam muitas vezes/sempre entre a administração dos medicamentos e 79% realizam muitas vezes/sempre após a administração. Concluiu-se que existiram fragilidades na prática do flushing em relação às recomendações de boas práticas que se configuram erros de medicação. Esses resultados indicam a necessidade de investimentos em melhorias nos cenários estudados em vista das boas práticas na terapia intravenosa. Em face disso, elaborou-se uma tecnologia na forma de guia de cuidado para a prática do flushing, a ser implementada na instituição como uma barreira à recorrência dos erros.

Maintaining the patency of the intravenous catheter used in hospitalized patients is essential to prevent damage and ensure the safety of intravenous therapy. Among the nursing care recommended for this maintenance is flushing, which is the application of saline solution in the lumen of the catheter with the objective of cleaning. This research aimed to: Characterize the practice of the nursing team in performing flushing for the maintenance of intravenous catheters used by hospitalized patients in intensive care settings; To evaluate the association of professional characteristics of the nursing team with the practice of flushing in the maintenance of intravenous catheters in hospitalized patients in intensive care settings; To analyze the practice of flushing in relation to the best evidence for the maintenance of intravenous catheters, from the perspective of patient safety; To develop, in the light of this analysis, a care technology aimed at promoting good nursing practices in performing flushing for the maintenance of intravenous catheters. Observational, cross-sectional study with a quantitative approach, carried out in four intensive care settings at a university hospital in the city of Rio de Janeiro. Participants were 108 nursing professionals who performed the maintenance of intravenous devices and were involved in the practice of flushing. Data were collected through observation using a checklist and application of a structured questionnaire, from November 2019 to January 2020. The analysis was carried out using descriptive, analytical and inferential statistics. A total of 404 observations of flushing were performed, of which 23% did not perform flushing and, in 77%, flushing was performed at some point during the handling of the intravenous device. Of the observations in which there was some moment of flushing, in 52% the professionals used a large volume bottle in the preparation; 97% used saline solution; 70% applied the technique of continuous pressure on the plunger of the syringe; 64.5% had not previously evaluated permeability. There was a predominance of flushing after drug administration, using the volume and 10 ml syringe. Having specific training related to venous access, knowledge of guidelines and time of professional practice of less than five years were variables that increased the chances of performing flushing in practice. As for the data from the questionnaire: 88% of the participants answered that they perform the flushing procedure in their practice; 93% described saline as the solution of choice; 49.5% reported flushing with continuous pressure on the syringe plunger, while 35% applied the push pause technique. Regarding the frequency, only 22% reported that they perform flushing before, between and after the administration of a medication. However, when this frequency was graded on a scale, in the data of the central venous catheter, the main device manipulated in practice, 64% reported that they often/always perform flushing before drug administration, 68% perform it often/always between administration of medications and 79% perform it often/always after administration. It was concluded that there were weaknesses in the practice of flushing in relation to the recommendations of good practices that configure medication errors. These results indicate the need for investments in improvements in the scenarios studied in view of good practices in intravenous therapy. In view of this, a technology was developed in the form of a care guide for the practice of flushing, to be implemented in the institution as a barrier to the recurrence of errors.

Entre los cuidados de enfermería recomendados para ese mantenimiento está el flushing, que es la aplicación de solución salina en la luz del catéter con el objetivo de limpiarlo. Esta investigación tuvo como objetivo: Caracterizar la práctica del equipo de enfermería en la realización de lavados para el mantenimiento de los catéteres intravenosos utilizados por pacientes hospitalizados en cuidados intensivos; Evaluar la asociación de las características profesionales del equipo de enfermería con la práctica de lavado en el mantenimiento de catéteres intravenosos en pacientes hospitalizados en cuidados intensivos; Analizar la práctica del flushing en relación a la mejor evidencia para el mantenimiento de catéteres intravenosos, desde la perspectiva de la seguridad del paciente; Desarrollar, a la luz de este análisis, una tecnología asistencial dirigida a promover buenas prácticas de enfermería en la realización de lavados para el mantenimiento de catéteres intravenosos. Estudio observacional, transversal, con abordaje cuantitativo, realizado en cuatro unidades de cuidados intensivos de un hospital universitario de la ciudad de Rio de Janeiro. Participaron 108 profesionales de enfermería que realizaban el mantenimiento de los dispositivos intravenosos y participaban en la práctica del flushing. Los datos fueron recolectados a través de la observación mediante una lista de cotejo y aplicación de un cuestionario estructurado, de noviembre de 2019 a enero de 2020. El análisis se realizó mediante estadística descriptiva, analítica e inferencial. Se realizaron un total de 404 observaciones de lavado, de las cuales el 23% no realizó lavado y en el 77% se realizó lavado en algún momento durante la manipulación del dispositivo intravenoso. De las observaciones en las que hubo algún momento de rubor, en 52% los profesionales utilizaron un biberón de gran volumen en la preparación; 97% utilizó solución salina; el 70% aplicó la técnica de presión continua sobre el émbolo de la jeringa; El 64,5% no había evaluado previamente la permeabilidad. Predominó el rubor tras la administración del fármaco, utilizando el volumen y jeringa de 10 ml. Tener formación específica relacionada con el acceso venoso, el conocimiento de las guías y un tiempo de ejercicio profesional inferior a cinco años fueron variables que aumentaron las posibilidades de realizar lavados en la práctica. En cuanto a los datos del cuestionario: el 88% de los participantes respondieron que realizan el procedimiento de lavado en su práctica; el 93% describió la solución salina como la solución de elección; El 49,5% refirió enjuagar con presión continua sobre el émbolo de la jeringa, mientras que el 35% aplicó la técnica de empujar pausa. En cuanto a la frecuencia, solo el 22% informó que realiza lavados antes, entre y después de la administración de un medicamento. Sin embargo, cuando se graduó esta frecuencia en una escala, en los datos del catéter venoso central, el principal dispositivo manipulado en la práctica, el 64% informó que a menudo/siempre realiza lavado antes de la administración del medicamento, el 68% lo realiza a menudo/siempre entre administración de medicamentos y el 79% lo realiza seguido/siempre después de la administración. Se concluyó que existieron debilidades en la práctica del flushing en relación a las recomendaciones de buenas prácticas que configuran errores de medicación. Estos resultados indican la necesidad de inversiones en mejoras en los escenarios estudiados en vista de las buenas prácticas en terapia intravenosa. Ante esto, se desarrolló una tecnología en forma de guía de cuidados para la práctica del rubor, para ser implementada en la institución como barrera a la reincidencia de errores.

Prática deliberada em ciclos rápidos aplicada em profissionais de enfermagem na punção venosa periférica / Rapid cycle deliberate practice applied to nurse technician professionals in peripheral venipuncture

Introdução: A Prática Deliberada em Ciclos Rápidos (PDCR) é uma estratégia educacional de simulação focada em promover um treinamento que permita o domínio de uma habilidade. A estratégia aplica o feedback direcionado e a oportunidade de repetição para que o participante alcance a maestria e/ou a alta performance. Estudos evidenciam melhorias significativas de habilidades dos profissionais de saúde quando treinados com PDCR em contexto de reanimação cardiopulmonar pediátrica. A partir da conjectura de que a PDCR pode ser aplicada em profissionais de saúde para melhoria de habilidades, formulou-se a hipótese que a PDCR melhora a performance técnica dos profissionais técnicos de enfermagem na punção venosa periférica (PVP) comparada ao treinamento de habilidade, que é outra estratégia mais comumente usada para ensino e capacitação profissional. Objetivos: Avaliar a PDCR como uma estratégia educacional e seu impacto na performance técnica dos profissionais técnicos de enfermagem na PVP; comparar a performance técnica dos profissionais técnicos de enfermagem na PVP após treinamento usando PDCR versus o treinamento de habilidade. Método: Estudo unicêntrico, experimental randomizado aberto, aplicado em 60 profissionais técnicos de enfermagem, divididos em dois grupos. A performance foi avaliada antes e após o treinamento, a partir do cálculo da taxa de acerto em 21 itens observados na execução do procedimento. A estratégia de treinamento do Grupo Intervenção (GI) foi a PDCR e do Grupo Controle (GC) foi o treinamento de habilidades de PVP. Resultados: O percentual global de acertos dos itens do procedimento de punção venosa periférica avaliados para o GC aumentou de 57,8% no pré-teste para 93,5% no pós-teste e o percentual de acertos para o GI aumentou de 59,4% para 96,0%. A variação da média no pré e pós-teste foi de 35,7% para GC e de 36,6% para o GI. Comparando pareadamente às taxas de acerto pré e pós-teste de cada grupo, ambos os treinamentos tiveram um efeito significativo em aumentar as taxas de acerto dos itens do procedimento de punção venosa periférica avaliados (p-valor <0,0001 para os dois grupos). Não houve diferença significativa entre as distribuições das taxas de acerto do pós-teste dos dois grupos (p-valor = 0,225). Usando a medida do tamanho de efeito dm de Cohen, o tamanho do efeito do treinamento do GC foi 2,95 e o tamanho de efeito do treinamento do GI foi 3,59. Usando a medida do tamanho de efeito Δ de Glass, o tamanho de efeito do treinamento do GC foi 2,24 e o tamanho do efeito do GI foi 2,63. Conclusão: Do ponto de vista da performance técnica, o treinamento com PDCR, assim como o treinamento de habilidades, resultou em melhorias de desempenho no procedimento de punção venosa periférica, evidenciadas pelo aumento de acertos no pós-teste em comparação com o pré-teste. Dessa forma, pode-se concluir que a PDCR pode ser aplicada como uma estratégia educacional para o treinamento da punção venosa periférica, não sendo inferior ao treinamento de habilidade. Sendo assim, pode-se interpretar que a aplicação da PDCR em contexto diferente do estudo original parece ser promissora e factível.

Introduction: Rapid Cycle Deliberate Practice (RCDP) is an educational simulation strategy that focuses on promoting simulation training that allows skill mastery achievement. The strategy applies directed feedback and opportunity for repetition until participants achieve mastery and/or high performance. Studies show significant improvements in the skills of healthcare professionals when trained with RCDP in pediatric cardiopulmonary resuscitation context. Based on the conjecture that RCDP can be applied to health professionals to improve skills, authors formulated the hypothesis that RCDP improves the technical performance of nursing technicians in peripheral venipuncture (PVP) compared to skill training, another strategy commonly used for teaching and professional training. Objectives: To evaluate RCDP as an educational strategy and its influence on the technical performance of nursing technicians in PVP; to compare the technical performance of nursing technicians in PVP after training using RCDP versus skill training. Methods: Single-center, open randomized experimental study, applied to 60 professional nursing technicians divided into two groups. Performance was evaluated before and after training, based on the calculation of the correct answer rate in 21 items observed during the procedure. The training strategy of the Intervention Group (IG) was RCDP and the Control Group (CG) was the skill training of PVP. Results: The overall percentage of correct answers for the items of the peripheral venipuncture procedure evaluated for the CG increased from 57.8% in the pre-test to 93.5% in the post-test and the percentage of correct answers for the IG increased from 59.4% to 96.0%. The mean variation in the pre and post- test was 35.7% for the CG and 36.6% for the IG. Comparing the pre and post-test hit rates of each group in parallel, both training strategies had a significant effect in increasing the hit rates of peripheral venipuncture procedure items that were evaluated (p-value <0.0001 for both groups). There was no significant difference between the distributions of the post- test hit rates of the two groups (p-value = 0.225). Using Cohen's dm effect size measure, the CG training effect size was 2.95 and the IG training effect size was 3.59. Using Glass's Δ effect size measure, the GC training effect size was 2.24 and the GI effect size was 2.63. Conclusion: From the point of view of technical performance, training with RCDP, as well as skills training, resulted in performance improvements in the peripheral venipuncture procedure, evidenced by the increase of correct answers in the post-test compared to the pre-test. Thus, the study concludes that RCDP works as an educational simulation strategy for peripheral venipuncture training since it showed not to be inferior to the skill training approach. Therefore, the application of RCDP in a different context from the original study seems to be propitious and viable.

A case report of catheter-related bloodstream infection due to Trichosporon coremiiforme in a patient with secondary neutropenia to HIV.

Here, we describe an invasive infection due to Trichosporon coremiiforme in an HIV positive patient with neutropenia. The strain was first erroneously identified as Trichosporon asahii by conventional methods, but correctly identified by mass spectrometry using matrix-assisted laser desorption/ionization time-of-flight technology (MALDI-TOF MS) and ribosomal DNA sequencing. The infection was successfully resolved after antifungal treatment with amphotericin B and fluconazole. This case report is a contribution to the study of T. coremiiforme infections and reinforces its relevance as a species capable of causing invasive human infection in immunocompromised patients and also contributes to the study of its susceptibility profile against antifungal drugs.

Bacteriemia relacionada con catéter por Staphylococcus aureus resistente a meticilina en pacientes con enfermedad renal crónica avanzada / Catheter-related bacteremia by methicillin-resistant Staphylococcus aureus in patients with advanced chronic kidney disease

Introducción: Staphylococcus aureus resistente a meticilina constituye la causa principal de bacteriemia relaciona a catéter en pacientes con enfermedad renal crónica avanzada en hemodiálisis. Objetivos: Estimar la tasa de incidencia de bacteriemia relaciona con catéter por Staphylococcus aureus resistente a meticilina en pacientes con enfermedad renal crónica avanzada en el Hospital General Freyre de Andrade, Cuba, y vigilar los valores de concentración mínima inhibitoria de vancomicina frente a los aislados recuperados de bacteriemia. Métodos: El estudio se realizó entre mayo 2017 y febrero 2018, el cual incluyó 64 pacientes con Staphylococcus aureus resistente a meticilina (total de los atendidos en hemodiálisis). De cada uno se recogió información acerca de tipo de acceso vascular y tiempo de uso; de los que desarrollaron un episodio sugerente de bacteriemia se obtuvieron muestras de sangre para hemocultivo. Se informó bacteriemia relacionada con catéter utilizando los criterios de Bouza y otros 2004 y estas se confirmaron debidas a Staphylococcus aureus resistente a meticilina tras determinar la concentración mínima inhibitoria de oxacilina, empleando el método de microdilución en caldo y los criterios del CLSI 2017. Asimismo se evaluó la concentración mínima inhibitoria de vancomicina. Resultados: Las tasas de incidencia de bacteriemia relaciona con catéter por S. aureus y Staphylococcus aureus resistente a meticilina fueron de 0,66 y 0,59/1000 días-catéter, respectivamente. Predominaron las bacteriemia relacionada con catéter en los pacientes con accesos vasculares temporales. No se observó incremento en la concentración mínima inhibitoria de vancomicina (1 y 2 (g/mL) para los aislados responsables de bacteriemia a repetición y persistente. Conclusiones: La tasas de incidencia de bacteriemia relacionada con catéter indican que en la unidad de hemodiálisis se mantienen buenas prácticas clínicas. Los valores de concentración mínima inhibitoria de vancomicina sugieren una reducción en la eficacia de la droga en el tratamiento(AU)

Introduction: Methicillin-resistant Staphylococcus aureus is the leading cause of catheter-related bacteremia in patients with advanced chronic kidney disease undergoing hemodialysis. Objective: Estimate the incidence rate of catheter-related bacteremia by methicillin-resistant Staphylococcus aureus in patients with advanced chronic kidney disease from General Freyre de Andrade Hospital in Cuba, and survey the vancomycin minimum inhibitory concentration values for isolates obtained from bacteremia. Methods: A study was conducted of 64 patients with methicillin-resistant Staphylococcus aureus (total of those undergoing hemodialysis) from May 2017 to February 2018. For each one of them, information was collected about vascular access type and time of use. Blood culture samples were obtained from patients who developed an episode suggesting bacteremia. Catheter-related bacteremia was reported using Bouza et al (2004) criteria, and it was confirmed as due to methicillin-resistant Staphylococcus aureus after determining oxacillin minimum inhibitory concentration by broth microdilution and CLSI 2017 criteria. Vancomycin minimum inhibitory concentration was also evaluated. Results: The incidence rates for catheter-related bacteremia by S. aureus and methicillin-resistant Staphylococcus aureus were 0.66 and 0.59/1000 catheter-days, respectively. A predominance was found of catheter-related bacteremia in patients with temporary vascular accesses. No increase was observed in vancomycin minimum inhibitory concentration (1 and 2 g/mlL for the isolates responsible for recurrent and persistent bacteremia. Conclusions: The incidence rates for catheter-related bacteremia show that good clinical practices are maintained in the hemodialysis unit. Vancomycin minimum inhibitory concentration values suggest a decrease in the efficacy of the drug during treatment(AU)

Risk Factors for Complications in Children with Staphylococcus aureus Bacteremia.

OBJECTIVES: To determine risk factors for complications in children with Staphylococcus aureus (S aureus) bacteremia, including methicillin resistance. STUDY DESIGN: Single center, retrospective cohort study of children ≤18 years of age hospitalized with S aureus bacteremia. We compared clinical characteristics and outcomes between those with methicillin-sensitive S aureus (MSSA) and methicillin-resistant S aureus (MRSA) bacteremia. Multivariate regression models identified risk factors associated with developing complications and with longer duration of bacteremia. RESULTS: We identified 394 episodes of S aureus bacteremia, 279 (70.8%) with MSSA, and 115 (29.2%) with MRSA. Primary site of infection was catheter-related in 34%, musculoskeletal in 30%, skin/soft tissue in 10.2%, pneumonia in 6.4%, and endovascular in 6.6%. Eight children (2.0%) died within 30 days because of S aureus bacteremia, 15 (3.5%) had recurrence within 30 days, and 38 (9.6%) had complications including septic emboli or a metastatic focus of infection. Methicillin resistance was associated with development of a complication (aOR 3.31; 95% CI 1.60-6.85), and catheter-related infections were less likely to be associated with a complication (aOR 0.40; 95% CI 0.15-1.03). In a Poisson regression analysis on duration of bacteremia, methicillin resistance, musculoskeletal infection, endovascular infection, black race, and delayed intervention for source control were significantly associated with longer duration of bacteremia. CONCLUSIONS: In this cohort of children with S aureus bacteremia, MRSA infections ere associated with longer duration of bacteremia and a higher likelihood of complications.

Fungemia causada por Rhodotorula en un lactante crítico / Fungemia caused by Rhodotorula in a critical infant

Introducción: Rhodotorula es considerada un microorganismo contaminante no virulento. Forma parte de la microbiota de la piel, las uñas y las mucosas. Se aísla con frecuencia del ambiente humanizado. Estas levaduras han surgido como patógenos oportunistas en pacientes con inmunodeficiencias, portadores de catéteres intravenosos de larga duración y otros. Objetivo: Informar a la comunidad pediátrica un nuevo caso de fungemia causada por Rhodotorula. Presentación del caso: lactante de 2 meses de edad, pretérmino de 32,1 semanas, con un peso al nacer de 1 800 gramos, que ingresa en la sala de cuidados intensivos del Hospital Pediátrico Provincial, Cienguegos, con el diagnóstico de una sepsis sin un foco primario definido. Después de 5 días de tratamiento con meropenem y vancomicina la fiebre cede y reaparece nuevamente pasados otros 5 días. En el momento en que la fiebre se reanuda tenía un catéter centrovenoso de ocho días de duración. En los hemocultivos realizados en esa fecha se aisló una Rhodotorula sp. Conclusiones: A pesar de que Rhodotorula es un microorganismo de baja virulencia, debe considerarse un potencial patógeno en pacientes con inmunosupresión y catéteres venosos centrales. Las especies de Rhodotorula se consideran intrínsecamente resistentes a los azoles y las equinocandinas, pero susceptibles a anfotericina B y flucitosina. En consecuencia, el tratamiento de elección preferido es con cualquier tipo de preparación de anfotericina B. El resultado alcanzado constituye un llamado de atención para la comunidad pediátrica nacional y foránea(AU)

ABSTRACT Introduction: Rhodotorula is considered a contaminating, non-virulent microorganism. It is part of the microbiota of the skin, nails and mucous membranes. It is often isolated from the humanized environment. These yeasts have emerged as opportunistic pathogens in patients with immunodeficiencies carrying long-term intravenous catheters. Objective: To inform to the pediatricians´ community a new case of fungemia due to Rhodotorula. Case presentation: 2-month-old, preterm infant of 32.1 weeks, with a birth weight of 1800 grams, who was admitted to Intensive Care service in Provincial Pediatric Hospital of Cienfuegos province with a diagnosis of sepsis without a defined primary focus. After 5 days of treatment with meropenem and vancomycin, the fever subsides and reappears again after another 5 days. By the time the fever reappears he had an 8-day central venous catheter. In the blood cultures carried out on that date a Rhodotorulasp was isolated. Conclusions: Although Rhodotorula is a low virulence microorganism, it should be considered as a potential pathogen in patients with immunosuppression and central venous catheters. Rhodotorula species are considered intrinsically resistant to azoles and echinocandins, but sensitive to amphotericin B and flucytosine. Consequently, the preferred treatment of choice is with any type of amphotericin B preparations. The results achieved constitute a call of attention to the national and foreign pediatrics´ community(AU)

Oclusões em cateteres venosos centrais de inserção periférica nos pacientes infantojuvenis em quimioterapia antineoplásica / Occlusions in peripherally inserted central venous catheters in children and adolescents undergoing antineoplastic chemotherapy

Pacientes infantojuvenis com câncer necessitam da rede venosa para a realização de diversos procedimentos, principalmente quimioterapia, sendo preciso optar por um acesso venoso seguro e de longa permanência. Este estudo aborda a utilização do cateter venoso central de inserção periférica. Apesar das vantagens deste cateter o seu uso pode estar relacionado à ocorrência de complicações, com destaque para as oclusões. O objetivo geral do estudo foi analisar a ocorrência de oclusões em cateteres venosos centrais de inserção periférica nos pacientes infantojuvenis em quimioterapia antineoplásica. Estudo de coorte retrospectiva, a partir de dados coletados em prontuários dos pacientes matriculados na oncologia pediatria no período entre 2013 e 2017 que atenderam aos seguintes critérios de inclusão: prontuários de pacientes de 0 a 19 anos, de ambos os sexos que realizaram tratamento quimioterápico no contexto ambulatorial, através do cateter venoso central de inserção periférica, com ou sem complicações do decorrer do tratamento. Foram critérios de exclusão: prontuários de pacientes com histórico de coagulopatia prévia; prontuários com informações incompletas ou ausentes; prontuários de pacientes que não tenham retirado o cateter venoso central de inserção periférica no momento da coleta de dados; prontuários de pacientes que realizaram o tratamento quimioterápico hospitalizados. O projeto de pesquisa foi aprovado pelo Comitê de Ética em Pesquisa no dia 07 de março de 2018. Para coleta dos dados foi utilizado um formulário elaborado pela pesquisadora, com base na revisão de literatura, na Classificação Internacional do Câncer na Infância e nas recomendações da Infusion Nurses Society, contendo variáveis relacionadas aos dados sociodemográficos, clínicos e específicos sobre oclusão do cateter. As análises foram realizadas por meio dos testes Qui-quadrado, t student, Mann-Whitney e cálculo do odds ratio como medida de associação. Como resultados, o estudo apontou que 219 cateteres venosos centrais de inserção periférica foram inseridos em 156 pacientes, desses 214 (97,7%) foram a primeira opção de cateter. Os tumores sólidos foram mais frequentes (89,7%). A oclusão ocorreu em 64,4% desses cateteres, sendo seu principal motivo de retirada (28,8%). A oclusão apresenta associação estatisticamente significativa com o tempo de permanência do cateter, com o uso de ciclofosfamida, com o diagnóstico de neuroblastoma, metástase óssea e com o número de sessões de quimioterapia. Assim foi possível concluir que a oclusão é uma complicação de destaque e o cateter venoso central de inserção periférica pode ser usado para vários tipos de tumores, e é uma opção segura e eficaz para quimioterapia a longo prazo. A melhor compreensão dos fatores que aumentam o risco de oclusão e o perfil desses pacientes pode nortear a tomada de decisão do enfermeiro diante de intercorrências e orientar o cuidado na prevenção da oclusão.

Pediatric cancer patients need the venous network to perform various procedures, especially for chemotherapy, and it is necessary to choose a safe and long-term venous access. This study addresses the use of the Peripherally Inserted Central Venous Catheter. Despite the advantages of this catheter, its use may be related to the occurrence of complications, especially occlusions. The aim of this study was to analyze the occurrence of occlusions in peripherally inserted central venous catheters in pediatric cancer patients undergoing chemotherapy. Retrospective cohort study, data collected from medical records of patients enrolled in pediatric oncology between 2013-2017, that met the following inclusion and exclusion criteria: Inclusion criteria: medical records of pediatric patients who underwent chemotherapy treatment in the outpatient setting through the central venous catheter. peripheral insertion, with or without complications during the course of treatment; Exclusion criteria: medical records of patients with a history of previous coagulopathy; medical records with incomplete or missing information; who did not remove the peripherally inserted central venous catheter at the time of collection; medical records of patients who underwent hospitalized chemotherapy treatment. For data collection, a form prepared by the researcher based on the literature review, the international classification of childhood cancer and recommendations of the Infusion Nurses Society, containing variables related to socio- demographic, clinical and specific occlusion data, was used. The analyzes were performed using Chi-square, t student, Mann-Whitney and odds ratio calculations as an association measure. As a result, the study found that 219 peripherally inserted central venous catheters were inserted in 156 patients, of which 214 (97.7%) were the first catheter option. Solid tumors were more frequent (89.7%). Occlusion occurred in 64.4% of these catheters, being its main reason for withdrawal (28.8%). Occlusion is statistically significant associated with catheter length of stay, use of cyclosphamide, diagnosis of neuroblastoma, bone metastasis, and number of chemotherapy sessions. Thus it was concluded that occlusion is a major complication and the peripheral insertion central venous catheter can be used for various types of tumors, and is a safe and effective option for long-term chemotherapy. A better understanding of the factors that increase the risk of occlusion and the profile of these patients can guide nurses' decision making in the event of complications and guide care in preventing occlusion.

Los pacientes con cáncer pediátrico necesitan la red venosa para realizar diversos procedimientos, especialmente para la quimioterapia, y es necesario elegir un acceso venoso seguro y a largo plazo. Este estudio aborda el uso del catéter venoso central insertado periféricamente. A pesar de las ventajas de este catéter, su uso puede estar relacionado con la aparición de complicaciones, especialmente oclusiones. El objetivo de este estudio fue analizar la aparición de oclusiones en catéteres venosos centrales insertados periféricamente en pacientes pediátricos con cáncer que reciben quimioterapia. Estudio de cohorte retrospectivo, datos recopilados de registros médicos de pacientes inscritos en oncología pediátrica entre 2013 y 2017 que cumplieron con los siguientes criterios de inclusión y exclusión: Criterios de inclusión: registros médicos de pacientes pediátricos que se sometieron a tratamiento de quimioterapia en pacientes ambulatorios a través del catéter venoso central. inserción periférica, con o sin complicaciones durante el curso del tratamiento; Criterios de exclusión: registros médicos de pacientes con antecedentes de coagulopatía previa; registros médicos con información incompleta o faltante; quién no retiró el catéter venoso central insertado periféricamente en el momento de la recolección; registros médicos de pacientes que se sometieron a tratamiento de quimioterapia hospitalizado. Para la recopilación de datos, se utilizó un formulario preparado por el investigador basado en la revisión de la literatura, la clasificación internacional del cáncer infantil y las recomendaciones de la Infusion Nurses Society, que contiene variables relacionadas con datos sociodemográficos, clínicos y de oclusión específica. Los análisis se realizaron utilizando Chi-cuadrado, t student, Mann-Whitney y cálculos de odds ratio como medida de asociación. Como resultado, el estudio encontró que se insertaron 219 catéteres venosos centrales insertados periféricamente en 156 pacientes, de los cuales 214 (97.7%) fueron la primera opción de catéter. Los tumores sólidos fueron más frecuentes (89,7%). La oclusión se produjo en el 64,4% de estos catéteres, siendo su principal motivo de retirada (28,8%). La oclusión es estadísticamente significativa asociada con la duración de la estancia del catéter, el uso de ciclofamida, el diagnóstico de neuroblastoma, metástasis óseas y el número de sesiones de quimioterapia. Por lo tanto, se concluyó que la oclusión es una complicación importante y que la inserción periférica del catéter venoso central puede usarse para varios tipos de tumores, y es una opción segura y efectiva para la quimioterapia a largo plazo. Una mejor comprensión de los factores que aumentan el riesgo de oclusión y el perfil de estos pacientes puede guiar la toma de decisiones de las enfermeras en caso de complicaciones y guiar la atención en la prevención de la oclusión.

[Nosocomial urinary tract infection: an analysis beyond urinary catheterization]. / Epidemiología de las infecciones urinarias asociadas a catéter y no asociadas a catéter en un hospital universitario de tercer nivel.

INTRODUCTION: Nosocomially acquired urinary tract infections (NAUTI) represent an important public health issue, but its characteristics when they are not catheter associated (CA-UTI) or when they take place outside intensive care units (ICU) are poorly understood. OBJECTIVES: To determine the patients' characteristics, etiology and antimicrobial susceptibility of NAUTI, both CA-UTI and no CA-UTI, in general ward and ICU. METHODS: We conducted a retrospective analytic cross-sectional study, between 2009 and 2013, in a third level universitary hospital. All NAUTI episodes were identified, classifying them as CA-UTI and no CA-UTI. RESULTS: We included 253 episodes of NAUTI, being CA-UTI (60,9%) more frequent than no CA-UTI. A 37,4% of no CA-UTI and 59,7% of CA-UTI were identified in ICU. The most frequently isolated microorganisms were Escherichia coli, Klebsiella pneumoniae and Enterococcus sp. A 19% of extended spectrum betalactamase producing gram negative bacilli were found, without differences between groups. CONCLUSION: Patients's comorbidities, microorganisms associated to NAUTI and its antimicrobial susceptibility were similar in CA-UTI and no CA-UTI, as in general ward and ICU.

Intermittent Catheterization and Urinary Tract Infection: A Comparative Study Between Germany and Brazil.

PURPOSE: The purpose of this study was to describe and compare factors that affect urinary tract infection (UTI) rates in people with spina bifida (SB) and neurogenic bladder dysfunction before and following initiation of intermittent catheterization (IC). DESIGN: A quantitative, descriptive, correlational study. SUBJECTS AND SETTING: The study included people who were from Germany, a high-income nation, and Brazil, a middle-income nation. Brazilian participants were recruited from a public rehabilitation hospital in the state of Minas Gerais. German participants were drawn from different regions of the country. The study sample included 200 participants; participants were either individuals diagnosed with SB and neurogenic bladder dysfunction and using IC, or caregivers of persons using IC for bladder management. METHODS: Data were collected through a survey questionnaire developed for urological follow-up of SB patients. A translated and validated version of the form was used to collect data in Germany. To evaluate annual episodes of UTI, we considered the number of symptomatic UTI before and after IC. RESULTS: Participants from Brazil were significantly younger than German patients (median age 9 vs 20 years, P < .001). Brazilians predominately used assisted catheterization (63.0%), whereas most Germans performed self-catheterization (61.0%). Use of IC greatly reduced the incidence of UTI in both groups (mean 2.8 episodes per year before IC vs mean 1.1 episodes after starting IC, P < .001). Women had a higher number of UTI, both before and after IC, but enjoyed greater reduction in UTI after initiating IC than men. Self-catheterization also promoted a greater reduction of UTI than assisted IC (P = .022). CONCLUSIONS: Intermittent catheterization reduced annual episodes of UTI in both samples despite differences in catheterization technique. Patients practicing and performing self-catheterization achieved a greater reduction than those who relied on assisted IC. Comparative studies among additional countries with varying median income levels are needed to better understand the needs of individuals with SB and their families, and to plan and implement safe nursing interventions.

Central Line-Associated Bloodstream Infection among Children with Intestinal Failure Presenting to the Emergency Department with Fever.

OBJECTIVES: To determine which factors confer the greatest risk of central line-associated bloodstream infection (CLABSI) in children with intestinal failure and fever presenting to an emergency department (ED), and to assess whether a low-risk group exists that may not require the standard treatment of admission for 48 hours on intravenous antibiotics pending culture results. STUDY DESIGN: This retrospective cohort study included children with intestinal failure and fever presenting to an ED over a 6-year period. Multivariable models were created using risk factors selected a priori to be associated with CLABSI as well as univariate predictors with P < .2. RESULTS: Among 81 patients with 278 ED encounters, 132 (47.5%) CLABSI episodes were identified. Multivariable models showed higher initial temperature in the ED (aOR, 1.99; 95% CI, 1.25-3.17) and low white blood cell count (aOR, 2.65; 95% CI, 1.03-6.79) and platelet count (aOR, 2.65; 95% CI, 1.20-5.87) relative to age-specific reference ranges were strongly associated with CLABSI. Among the 63 encounters in which the patient had none of these risk factors, the rate of CLABSI was 25.4%. CONCLUSIONS: Children with intestinal failure who present to the ED with fever have high rates of CLABSI. Although higher temperature in the ED, lower white blood cell count, and lower platelet count are strongly associated with CLABSI, patients without these risk factors frequently have positive blood cultures as well. Antibiotics should, therefore, be given to all children with intestinal failure and fever until CLABSI is ruled out.

Analysis of complications related to dialysis catheters in cancer patients

Background: Data on renal replacement therapy (RRT) in cancer patients with acute kidney injury (AKI) in the intensive care unit (ICU) and how these factors influence the efficiency of dialysis and the outcomes of these patients are scarce. We aim to describe the predictive clinical characteristics of hemodialysis catheter-related complications in critically ill cancer patients with acute kidney injury. Methods: This is a retrospective cohort study of 62 cancer patients subjected to short-term hemodialysis catheter implants. We evaluated the clinical characteristics of patients and the complications related to catheter implantation: mild malfunction, characterized by reversal of access lines; infections; and catheter replacement due to severe malfunction or infections. The outcomes analyzed were recovery of renal function, discharge from the ICU, and death. Results: The most frequent complications were related to mild malfunction, which justified dialysis line reversal in 21.3% of the patients. The complication rate was higher in patients undergoing conventional hemodialysis, in those with coronary disease, and in those who had more than three dialysis sessions. The presence of metastasis was more frequently related to catheter reversals. Patients with mild or severe malfunction were more likely to be hospitalized for more than 18 days in the ICU. All patients with mild malfunction had hospitalization times greater than 28 days. Conclusions: Hemodialysis catheter-related complications were associated with longer ICU and hospital stays in cancer patients with AKI. Mild malfunction of the hemodialysis catheter was the most frequent complication. Patients with metastasis and sepsis, who used diuretics, and who used intermittent dialysis methods had milder catheter malfunctions

Epidemiología de las infecciones urinarias asociadas a catéter y no asociadas a catéter en un hospital universitario de tercer nivel / Nosocomial urinary tract infection: an analysis beyond urinary catheterization

Resumen Introducción: Las infecciones urinarias asociadas a la atención de la salud (ITU-AAS) representan un importante problema sanitario, siendo poco conocidas sus características cuando no están asociadas a cateterización urinaria u ocurren fuera de unidades de cuidados intensivos (UCI). Objetivos: Determinar las características de los pacientes con ITU-AAS, etiología y susceptibilidad antimicrobiana de las mismas, tanto asociadas a catéter (ITU-C) como no asociadas a catéter (ITU-noC), en UCI y en sala general. Materiales y Métodos: Se realizó un estudio analítico retrospectivo de corte transversal entre 2009 y 2013 en un hospital universitario de tercer nivel. Se identificaron todos los episodios de ITU-AAS, diferenciándolas en ITU-C e ITU-noC. Resultados: Se incluyeron 253 episodios de ITU-AAS, siendo más frecuentes las ITU-C (60,9%) respecto a ITU-noC. Un 37,4% de ITU-noC y 59,7% de ITU-C ocurrieron en UCI. Los microorganismos aislados más frecuentemente fueron Escherichia coli, Klebsiella pneumoniae y Enterococcus sp. El 19% de los bacilos gramnegativos fueron productores de β-lactamasa de espectro extendido, siendo su frecuencia similar en ambos grupos. Conclusión: Las co-morbilidades de los pacientes con ITU-AAS, los agentes etiológicos responsables y sus correspondientes espectros de sensibilidad, fueron similares en los grupos de ITU-C e ITU-noC, tanto en sala general como en UCI.

Endocarditis infecciosa asociada a catéter de hemodiálisis: hallazgos clínicos y ecocardiográficos / Infective endocarditis associated with hemodialysis catheters: clinical and ehocardiographic findings

Resumen: Hallazgos clínicos y ecocardiográficos en pacientes con endocarditis infecciosa (E.I.) asociada a catéter de hemodiálisis (CHD) fueron comparados con sujetos controles con E.I. "habitual". Pacientes y métodos: Del total de registros ecocardiográficos de una Clínica privada de Antofagasta entre 2009 y 2014, 4 pacientes presentaban E.I. asociada CHD (E.I.-CHD) y 16 otro tipo de E.I. (controles). Se compararon ambos grupos clínicamente y en las distintas modalidades de ecografía, para evaluar el aporte de cada una de ellas en el diagnóstico, manejo y comprensión del mecanismo de producción de la E.I. Resultados: El periodo del inicio de los síntomas hasta la hospitalización y el comprendido entre ésta hasta el fallecimiento fue variable, con tendencia a fallecimiento más precoz en el grupo E.I.-CHD (promedio 14,6 vs 20,6 días en el grupo control). La edad en E.I.-CHD fue mayor (65 versus 62.2 años), con mayor incidencia de las 3 comorbilidades más frecuentes: hipertensión arterial (100% versus 56,25%), diabetes mellitus (75% versus 50%) e insuficiencia cardíaca (75% versus 31,25%). La mortalidad fue 18.75% en el grupo control y 75% en la E.I.-CHD. En los pacientes con E.I.-CHD se aisló: Cándida (50%), Bacilos gram negativo (Stenotrophomonas maltophilia) (25%) y SAMR (25%) mientras que en el grupo control fueron aislados Enterococcus faecalis (25%), Streptococcus viridans (12.5%), Streptococcus spp (6.25%), Staphylococcus aureus (6.25%), Streptococcus grupo C (6.25%), Abiotrophia defectiva (6.25%) y Streptococcus pneumoniae (6.25). En 31.25% de los casos los hemocultivos fue-ron negativos. La localización más frecuente de las vegetaciones en los pacientes con E.I.-CHD correspondió a la pared de AD, sitio de impacto del jet del CHD, en un 100%, seguida por CHD 50%, tricúspide 25% y aórtica 25%. En los controles las localizaciones fueron 75% en válvula aórtica y 25% en válvula mitral. En el grupo de E.I.-CHD, la mitad presentó disfunción sistólica e insuficiencia valvular, mientras que en el grupo control fue predominante la insuficiencia valvular (62,5%) seguida por la perforación de velo (25%). Conclusión: En las E.I.-CHD se aislaron gérmenes asociados a un peor pronóstico (hongos o bacterias atípicas), con altísima mortalidad. La localización principal de las vegetaciones fue en la pared de la aurícula derecha (AD), alrededor de la desembocadura de la vena cava inferior (VCI), sitio de impacto del jet del CHD, y en el tercio distal del catéter. Clinical and echocardiographic findings in patients with infective endocarditis (I.E.) associated to the presence of hemodialysis catheters (HDC) were compared to those in subjects with other types of I.E.

Abstracts: Methods: Between 2009 and 2014 an echocardiographic diagnosis of I.E. was established in 4 subjects with a hemodialysis catheter in place and 16 patients had a common variety of I.E. (controls). Clinical and echocardiographic findings, including echocardiographic modalities were compared between groups. Results: Time from onset of symptoms and time to patient death were shorter in I.E.-HDC patients compared to controls (mean 14.6 vs 20.6 days, respectively. I.E. -HDC patients tended to be older (65.0 vs 62.2 years old). The incidence of main comorbidities was higher in I.E.-HDC: hypertension (100% vs 56.2%), diabetes (75 vs 59%) and heart failure (75% vs 31.2%), respectively. Mortality was much higher in I.E-HDC (74% vs 18%). Infective agents also differed between groups: I.E.-HDC was associate to C albicans (50%), Gram negative rods (Stenotrophomonas maltophilia) (25%) y SAMR (25%). In contrast, the agents involved in controls were E faecalis (25%), S viridans (12.5%), S. group C (6.25%), S aureus (6,25%), group C Streptococcus (6.25%), Abiotrophic defectiva (6.25%) and S pneumoniae (6.25%). Overall, blood cultures were negative in 31.2% patients. Among patients with I.E.-HDC vegetations were most commonly found at the right atrial wall (100%), on the catheter (50%), at the tricuspid valve (25%) and at the aortic valve (25%). In non I.E.-HDC, vegetations were located at the aortic valve (75%) and the mitral valve (25%). Half the patients with I.E.- HDC patients presented ventricular dysfunction and valvular regurgitation while control patients had predominantly valvular insufficiency (62.5%) or leaflet perforation (25%). Conclusion: Mortality in I.E.-HDC patients was very high, associated to the presence of aggressive microbial or fungal agents. Vegetations were most commonly located at the right atrial wall, around de junction with the inferior vena cava and on the catheter itself.

Quality of Life of Intermittent Urinary Catheterization Users and Their Caregivers: A Scoping Review.

AIMS: This study aimed to examine and map the scientific evidences regarding quality of life in neurogenic bladder patients and consequently their caregivers by means of a scoping review. DESIGN: This is a scoping review proposal of the Joanna Briggs Institute. METHODS: It was conducted to examine and map the scientific evidences about quality of life (QoL) in neurogenic bladder patients and their caregivers, to identify the meanings attributed to QoL and its relation with intermittent urinary catheterization. The following guiding question was: "What scientific evidence has been produced on the QoL of neurogenic bladder patients using intermittent urinary catheterization and their caregivers?" A total of 2945 research studies were identified using The Cochrane Library, CINAHL, LILACS, Academic Search Premier (via EBSCO platform), PubMed, SCOPUS, the platforms Web of Science, the b-on and Gray Literature. The keywords established were patient, intermittent urinary catheterization, neurogenic urinary bladder, quality of life and caregiver. RESULTS: From 2,945 studies, 13 studies were selected. Most of the selected studies that analyzed variables related to the patients' QoL were regarding the urinary catheterization technique, assessment of urinary incontinence, individual perceptions of the procedure and experiences with urinary catheter in childhood and adult life. The meanings attributed to QoL, when compared to adult and child individuals with normal bladder functioning, presented lower QoL scores. Concerning caregivers, the QoL of caregivers of children using intermittent urinary catheterization demonstrated low scores. LINKING EVIDENCE TO ACTION: The QoL of patient's who use intermittent urinary catheterization can be determined by improvement of urinary symptoms and self-confidence. Research related to QoL of patients who use urinary catheter indicates the importance of adequate professional support and appropriate health public policies.

Tratamiento endovascular exitoso de aneurisma de aorta torácica secundario a infección de catéter de arteria umbilical en un recién nacido pretérmino / Successful endovascular treatment of thoracic aortic aneurysm secondary to infection of the umbilical artery catheter in preterm infants

Los aneurismas aórticos en la población pediátrica son poco frecuentes. El uso de catéteres de arteria umbilical en neonatos se ha asociado a infección y en algunas oportunidades a formación de aneurismas aórticos. La reparación quirúrgica de estos aneurismas es una forma de terapia; sin embargo, la intervención percutánea con stents pudiese proveer una vía alternativa de tratamiento con menores complicaciones. El objetivo de este reporte es dar a conocer el alcance terapéutico de un procedimiento híbrido, en el que el desarrollo de la técnica quirúrgica y percutánea en conjunto ofrece otra alternativa terapéutica menos invasiva que la cirugía vascular abierta, para la reparación de aneurismas aórticos o de sus ramas principales. Caso clínico: Recién nacido de pretérmino, 30 semanas, peso 1.335 g. Se instaló catéter en arteria umbilicar que se retiró a los 14 días por infección. Evolucionó con sepsis a Staphylococcus aureus. Ecocardiograma y angiotac confirman AAT, se manejó mediante procedimiento híbrido, cirugía e instalación endovascular de 2 stents recubiertos (Atrium V12 XR Medical Corp, Hudson, NH). Los controles clínicos post procedimiento como la ecotomografía abdominal confirmaron el éxito del tratamiento. Conclusión: El procedimiento endovascular de reparación de aneurisma de la aorta en recién nacidos prematuros puede ser considerado en el momento de decir la terapéutica de esta enfermedad y podría evitar los riesgos asociados a cirugía abierta. Sin embargo, obliga a un seguimiento y control durante el crecimiento del paciente por la eventual necesidad de redilatar los stents implantados. Se desconoce cómo será la evolución de los procedimientos endovasculares neonatales en el futuro.

Aortic aneurysms (AA) in the paediatric population are uncommon. The use of umbilical catheters in neonates has been associated with infections and, on some occasions, the formation of aortic aneurysms. The surgical repair of these aneurysms is one type of treatment; however, percutaneous intervention with stents could provide an alternative treatment route, with fewer complications. The aim of this report is to present the therapeutic scope of a hybrid procedure, in which the combined surgical and percutaneous technique offers a less invasive alternative to open surgery for the repair of aortic aneurysms or their main branches. Clinical case: The case concerns a pre-term newborn of 30 weeks weighing 1,335 g. An umbilical catheter was introduced, which was withdrawn at 14 days due to an infection. It developed as Staphylococcus aureus with sepsis. The echocardiogram and Angio-CT confirmed AA, which were managed using a hybrid procedure of surgery and the endovascular implantation of 2 coated stents (Atrium V12 XR Medical Corp, Hudson, NH). The post-procedure clinical follow-ups, including abdominal echo-tomography, confirmed the success of the treatment. Conclusion: The endovascular aortic aneurysm repair procedure in premature newborns may be considered when deciding treatment of this disease, and could avoid the risks associated with open surgery. However, follow-up and monitoring is required while the patient grows up, due to the possibility that the implanted stents require re-dilating. The outcomes of neonatal endovascular procedures in the future are unknown.

Clinical outcomes and mortality in elderly peritoneal dialysis patients.

OBJECTIVES: To evaluate the clinical outcomes and identify the predictors of mortality in elderly patients undergoing peritoneal dialysis. METHODS: We conducted a retrospective study including all incident peritoneal dialysis cases in patients ≥65 years of age treated from 2001 to 2014. Demographic and clinical data on the initiation of peritoneal dialysis and the clinical events during the study period were collected. Infectious complications were recorded. Overall and technique survival rates were analyzed. RESULTS: Fifty-eight patients who began peritoneal dialysis during the study period were considered for analysis, and 50 of these patients were included in the final analysis. Peritoneal dialysis exchanges were performed by another person for 65% of the patients, whereas 79.9% of patients preferred to perform the peritoneal dialysis themselves. Peritonitis and catheter exit site/tunnel infection incidences were 20.4±16.3 and 24.6±17.4 patient-months, respectively. During the follow-up period, 40 patients were withdrawn from peritoneal dialysis. Causes of death included peritonitis and/or sepsis (50%) and cardiovascular events (30%). The mean patient survival time was 38.9±4.3 months, and the survival rates were 78.8%, 66.8%, 50.9% and 19.5% at 1, 2, 3 and 4 years after peritoneal dialysis initiation, respectively. Advanced age, the presence of additional diseases, increased episodes of peritonitis, the use of continuous ambulatory peritoneal dialysis, and low albumin levels and daily urine volumes (<100 ml) at the initiation of peritoneal dialysis were predictors of mortality. The mean technique survival duration was 61.7±5.2 months. The technique survival rates were 97.9%, 90.6%, 81.5% and 71% at 1, 2, 3 and 4 years, respectively. None of the factors analyzed were predictors of technique survival. CONCLUSIONS: Mortality was higher in elderly patients. Factors affecting mortality in elderly patients included advanced age, the presence of comorbid diseases, increased episodes of peritonitis, use of continuous ambulatory peritoneal dialysis, and low albumin levels and daily urine volumes (<100 ml) at the initiation of peritoneal dialysis.
