Manejo de PICC en el Servicio de Urgencias de un hospital universitario / Use of PICC at the University Hospital Emergency Unit

Para gestionar el capital venoso del paciente con seguridad y responsabilidad es necesario aumentar la calidad de los cuidados proporcionados, unificando y estandarizando los criterios de actuación, basándose siempre en la mejor evidencia científica. Las enfermeras de los Servicios de Urgencias deben aplicar la evidencia en el manejo del catéter venoso central de inserción periférica (PICC), conocer el protocolo aprobado por la Dirección Asistencial de su hospital y, sobre todo, evitar la variabilidad en la actuación, que podría aumentar los riesgos relacionados con la atención sanitaria, así como la desconfianza del paciente. Mantener actualizados los conocimientos y promover la adquisición de habilidades en la práctica clínica es de suma importancia para garantizar cuidados de calidad en el manejo de este tipo de catéteres, debiéndose comprobar periódicamente el grado de cumplimiento de la evidencia recogida en los protocolos existentes en el hospital. Las enfermeras tienen el reto de estar al día en el manejo de los accesos vasculares, y deben responder con seriedad y evidencia a los cuidados que necesitan los pacientes a los que se atienden. En este manuscrito se objetiva la necesidad de formar y capacitar de forma continua a los profesionales para el manejo adecuado del PICC. (AU)

In order to manage the venous resource of the patient safely and with responsibility, it is necessary to increase the quality of care provided, unifying and standardizing performance criteria, always based on the best scientific evidence. Emergency Unit nurses must apply evidence in their use of the peripherally inserted central venous catheter (PICC), they must know the protocol approved by the Patient Care Management in their hospital and, most of all, must avoid variability of action, which could increase the risks associated with healthcare as well as mistrust by patients. It is extremely important to keep an updated knowledge and to promote the acquisition of clinical practice skills, in order to guarantee quality care in the use of this type of catheters; the level of compliance of the evidence collected in the hospital protocols must be confirmed periodically. Nurses face the challenge of being updated in the management of vascular accesses, and must give response with seriousness and evidence to the care needed by their patients. This manuscript sets out objectively the need for continuous training and qualification for professionals regarding the adequate use of PICC. (AU)

Impact of the COVID-19 pandemic in colorectal cancer diagnosis and presentation / Impacto de la pandemia del COVID-19 en el diagnóstico y la presentación del cáncer colorrectal

Background and objective: The COVID-19 pandemic has been associated with a decrease in the colorectal cancer (CRC) incidence, due to the disruption of screening programmes and a downscaling of endoscopic activity. The endpoint of this study is to evaluate if the pandemic has led to a change in CRC diagnostic rate and presentation in our population. Methods: Multicenter retrospective study of all public hospitals of the Aragon region, attending a population of 1,329,391 inhabitants. We have analyzed all CRC cases detected and endoscopic units workload the year before the pandemic onset (1 March 2019–14 March 2020) and the first year of the COVID-19 pandemic (15 March 2020–28 February 2021). Results: The diagnosis of CRC cases dropped a 38.9% (888 pre-pandemic vs 542 pandemic cases). Also, there were 30.3% less colonoscopies performed (24,860 vs 17,337). During the pandemic, CRC cases were diagnosed in older patients (72.4±12.2 vs 71.2±12.1 years, p=0.021), and had more frequently severe complications at diagnosis (14.6% vs 10.4%, p=0.019). Moreover, most CRC cases were diagnosed in symptomatic patients (81.4%). No significant difference was found in CRC stage at diagnosis, although stage IV was more frequent (20.1% vs 16.1%). Most hospitals reported a lower workload of endoscopic activity. Conclusion: CRC diagnostic rate was lower after the onset of the pandemic. CRC was diagnosed in older patients and was more frequently associated with complications. After the onset of the pandemic, the endoscopic units did not reach the workload performed previously. (AU)

Introducción y objetivo: La pandemia del COVID-19 ha provocado una disminución en la incidencia de cáncer colorrectal (CCR) tras la suspensión de los programas de cribado y la reducción de la actividad endoscópica. El objetivo del estudio es evaluar si la pandemia se ha asociado a un cambio en la incidencia y presentación del CCR en nuestra población. Métodos: Estudio multicéntrico, retrospectivo de todos los hospitales públicos de Aragón, con 1.329.391 habitantes. Analizamos todos los CRC detectados y la carga laboral de las unidades de endoscopia del año prepandémico (1 marzo 2019 – 14 marzo 2020) y el primer año de la pandemia (15 marzo 2020 – 28 febrero 2021). Resultados: El diagnóstico de CRC descendió un 38,9% (888 casos prepandemia vs. 542 en pandemia). Se realizaron un 30,3% menos de colonoscopias (24.860 vs. 17.337). El CRC en pandemia se diagnosticó en pacientes de mayor edad (72,4±12,2 vs 71,2±12,1 años; p=0,021) y presentaron más complicaciones graves en el momento del diagnóstico (14,6 vs. 10,4%; p=0.019). La mayoría de los CRC se diagnosticaron en pacientes sintomáticos (81,4%). No hubo diferencias en el estadio al diagnóstico aunque el estadio iv fue más frecuente (20,1 vs. 16,1%). La mayoría de los hospitales reiniciaron la actividad endoscópica con una menor carga laboral. Conclusión: La tasa diagnóstica de CRC descendió tras el inicio de la pandemia, el CRC fue diagnosticado en pacientes mayores y se asoció con más complicaciones al diagnóstico. Tras el inicio de la pandemia, la mayoría de los hospitales reiniciaron su actividad con una menor carga laboral. (AU)

Citrate versus acetate-based dialysate in on-line haemodiafiltration. A prospective cross-over study.

BACKGROUND AND AIMS: A bicarbonate dialysate acidified with citrate (CD) has been reported to have local anticoagulant effect and improves biocompatibility. This study examines the effect of CD on dialysis efficiency, coagulation, acid-base status, electrolytes, and inflammation in patients in on-line hemodiafiltration (OL-HDF). METHODS: 35 patients in OL-HDF were enrolled in a prospective, cross-over study for a 24-week period and two phases alternating CD and acetate dialysate fluid (AD). Parameters on study were predialysis levels of bicarbonate and ionic calcium, reactive C Protein (CRP), and beta-2 microglobulin (B2MG) and postdialysis levels of activated tromboplastine time, bicarbonate, and ionized calcium. RESULTS: No significant differences in coagulation parameters, pH, and predialysis bicarbonate were found. The postdialysis bicarbonate and postdialysis calcium were lower with CD. Dialysis efficiency was greater with CD. Regarding inflammatory parameters, both CRP and B2MG were lower using CD. CONCLUSION: The use of CD is safe and effective in OL-HDF, and it improves dialysis efficacy, postdialysis alkalosis, and inflammation.

Influence of cardiac rehabilitation on natriuretic peptides.

OBJECTIVE: Cardiac rehabilitation programmes result in reduced morbidity and mortality and improvement of functional class. Behaviour of natriuretic peptides coupled to these programmes is not well established. Our study's objective is to evaluate the behaviour of natriuretic peptides in a sample of patients undergoing a cardiac rehabilitation programme. METHODS AND RESULTS: Moderate to high-risk patients undergoing a cardiac rehabilitation programme were included. Demographic and clinical characteristics were recorded. We performed four N-terminal pro-brain natriuretic peptide (NT-proBNP) plasma determinations: on the first and last programme day, before and after training. To evaluate functional capacity, a stress test before and after the exercise programme was performed. Eighty-three patients were included. Exercise produces increased levels of NT-proBNP, although in the last exercise session the increase was lower (35.91 vs. 31.49 ng/ml (P = 0.71)). Patients with left ventricular dysfunction present higher NT-proBNP levels. After the rehabilitation programme we observed a significant improvement of functional capacity by 1.5 METS on average (P = 0.001), but not in the subgroup with lower NT-proBNP levels. CONCLUSIONS: Basal levels of peptides did not change significantly after the programme but rose with the workout, especially in patients with left ventricular dysfunction. Patients with higher baseline levels obtained greater functional recovery. We conclude that NT-proBNP measurement may be useful in selecting patients to perform a cardiac rehabilitation programme.
