PiccPed® app impact on nurses' knowledge to prevent adverse events for peripherally inserted central catheters (PICC) in pediatric and neonatal healthcare: A quasi-experimental study.

BACKGROUND: The PiccPed® health application was developed to support clinical decision-making in peripherally inserted central catheter (PICC) management. We aimed to evaluate its impact on nurses' knowledge regarding the prevention of PICC-associated adverse events in pediatrics and neonatology. METHODS: A quasi-experimental, pre-post intervention study, was conducted with a dependent/paired sample of pediatric and neonatal nurses from two tertiary hospitals in South Brazil. Data were collected from October 2022 to January 2023 across three phases: pre-, intervention (use of the PiccPed®) and post-test. Study outcomes were a knowledge test (15 questions) of evidence-based PICC maintenance procedures, and PiccPed® app time spent and screens used. RESULTS: A total of 56 nurses completed the study. The post-test mean score was significantly higher (12/15; standard deviation (SD) 1.9) in comparison with the pre-test (mean 9/15; SD 2.2). The change in scores was significantly higher for nurses without postgraduate qualifications, in comparison to those with (Mean Difference 1.26; p = 0.039). Each minute using the app resulted in a significant increase of 0.04 points (95% confidence interval 0.01-0.08; p = 0.014) on the mean post-test score (10.94 points). CONCLUSION: The research demonstrated that PiccPed® enhances nurses' learning regarding the prevention of adverse events associated with PICC maintenance in pediatrics and neonatology. APPLICATION TO PRACTICE: The app can be safely and effectively used for training and continuing education of nurses who care for children and neonates with PICCs.

Factors associated with the disinfection of devices attached to peripheral intravenous catheters performed by the nursing team in pediatric units.

Background: Peripheral intravenous catheterization, as well as drug administration through it, represents one of the most performed procedures by the Nursing team and, for that, precautions need to be adopted to offer harm-free care. Objective: To verify the association of Nursing professionals' work shift and training time with proper disinfection of intravenous catheter devices in pediatric units. Methods: A cross-sectional and analytical study conducted between June and August 2021 in three hospitalization units of a Pediatric Hospital. The inclusion criterion was drug administration via peripheral intravenous catheters performed by Nursing professionals. The data were analyzed according to inferential statistics, adopting p ≤ .05 as significance level. Results: There were a total of 385 observations of drug administration procedures. The device was not disinfected in 60.3% of the cases, there was no friction at the suitable time in 86.3%, and the disinfectant was not allowed to dry in 72.5%. The work shift exerted no influence on performance of the disinfection procedure (p = .376). However, longer training time was associated with a lower rate in performing such procedure (p < .001). Conclusion: Performing friction below the recommended time can cause a false sense of prevention of catheter-associated bloodstream infection; therefore, training sessions and strategies for adherence to the disinfection procedures should be considered, mainly for professionals with more training time.

Compliance with central venous catheter infection prevention practices after intervention with simulation.

OBJECTIVES: to assess the effect of an educational intervention based on clinical simulation on nursing professionals' compliance with practices to prevent peripherally inserted central venous catheter-associated primary bloodstream infections in a Neonatal Intensive Care Unit. METHODS: a quasi-experimental study, with preand post-intervention assessment with a single group. The population consisted of 41 nursing professionals, with 31 observations being made before and after the intervention. Analyzes were performed using descriptive statistics and the McNemar non-parametric test. A significance level of 5% was adopted. RESULTS: after the intervention, there was an increase in compliance with prevention practices of surgical antisepsis and professional hand hygiene, skin antisepsis with chlorhexidine, waiting for the time of the effect of alcoholic chlorhexidine and compliance with the sterile technique. CONCLUSIONS: the educational intervention showed an effect on increasing compliance with catheter-associated infection prevention practices.

Implementation of upfront DPYD genotyping with a low-cost and high-throughput assay to guide fluoropyrimidine treatment in cancer patients.

OBJECTIVES: Genetic variants in the dihydropyrimidine dehydrogenase (DPYD ) gene are associated with reduced dihydropyrimidine dehydrogenase enzyme activity and can cause severe fluoropyrimidine-related toxicity. We assessed the frequency of the four most common and well-established DPYD variants associated with fluoropyrimidine toxicity and implemented a relatively low-cost and high-throughput genotyping assay for their detection. METHODS: This study includes 457 patients that were genotyped for the DPYD c.1129-5923C>G, c.1679T>G, c.1905 + 1G>A and c.2846A>T variants, either by Sanger sequencing or kompetitive allele specific PCR (KASP) technology. Of these, 172 patients presented toxicity during treatment with fluoropyrimidines (post-treatment group), and 285 were tested before treatment (pretreatment group). RESULTS: Heterozygous DPYD variants were identified in 7.4% of the entire series of 457 patients, being the c.2846A>T the most frequent variant. In the post-treatment group, 15.7% of the patients presented DPYD variants, whereas only 2.5% of the patients in the pretreatment group presented a variant. The KASP assays designed in this study presented 100% genotype concordance with the results obtained by Sanger sequencing. CONCLUSIONS: The combined assessment of the four DPYD variants in our population increases the identification of patients at high risk for developing fluoropyrimidine toxicity, supporting the upfront routine implementation of DPYD variant genotyping. Furthermore, the KASP genotyping assay described in this study presents a rapid turnaround time and relatively low cost, making upfront DPYD screening feasible in clinical practice.

Opioids and constipation therapy in the last week of life: Their impact on patients, caregivers, and the location of death.

The use of opioids to control pain at the end of life may cause constipation, a symptom that can negatively influence the well-being of patients and caregivers. The main aim of this study was to evaluate the impact of constipation on symptomatic control and patients' overall quality of life at this stage. A particular focus was placed on opioids. We also intended to investigate whether constipation and caregiver fatigue is related to the place of death (hospital vs home). The approach of 121 patients followed in 2021 in their last week of life by a home team specialized in palliative care was analyzed in an observational, retrospective, non-interventional study. The patients were followed up for an average of 39.7 days. A total of 82.6% wished to die at home, which occurred in 74% of the cases. The constipation prevention protocol reduced constipation by 55.1%. It seems that morphine is more related with constipation and tapentadol seems to reduce constipation induced by opioids. Patients tended to die in hospitals when their caregivers were exhausted; however, it was not possible to determine a cutoff point using the Zarit scale, which was used to assess caregiver burden. Constipation in the last week of life does not seem to influence the well-being of patients or their caregivers significantly and the individualization of intensive treatment of constipation is needed. Different opioids have different probabilities of causing adverse effects such as constipation. Future special support mechanisms can be created and activated for the most tired caregivers to avoid exhaustion and promote death at home, if that is the patient's will.

RESULTS: All disinfectants reduced the bacterial load (P<0.001), especially the chlorhexidine solutions. Mechanical friction should follow guidelines. CONCLUSION: This study found that all tested disinfectants effectively reduced the bacterial load and more clinical studies must be developed with a focus on the Brazilian clinical practice of needleless connector disinfection.

Liver Transplantation for Treatment of Unresectable Spontaneous Ruptured Hepatocellular Adenoma: A Rare Indication.

Hepatocellular Adenomas (HA) are rare benign tumors of the liver which occur predominantly in young women. Although benign, HA may have complications such as hemorrhage and malignant transformation. So, sometimes conservative management is not enough. We report a case of a 26-year-old woman on oral contraceptives who presented with acute abdominal pain and signs of hemodynamic shock. She underwent transarterial embolization due to the presence of multiple HA with rupture and active hemorrhage. This minimally invasive treatment failed to control the disease. The patient presented a progressive increase in the size of the masses with signs of recent hemorrhage, and the HA became unresectable, so she underwent liver transplantation. Liver transplantation is rarely indicated for the treatment of HA; however, in unresectable masses, it should be considered to prevent potential rupture with hemorrhage or malignant transformation.

ABSTRACT Objective: to identify disinfection methods for intravenous catheter hubs and needleless connectors in hospitalized patients, as well as to verify the effectiveness of the interventions to prevent bloodstream infections associated with intravenous catheters. Method: a scoping review following the Joanna Briggs Institute recommendations. The search was conducted in the following electronic databases: PubMed, Embase, Cochrane Library, Literatura Latino-Americana e do Caribe em Ciências da Saúde, Base de Dados Enfermagem and Bibliografía Nacional en Ciencias de la Salud Argentina, as well as in studies indicated by experts. The search was conducted until September 2020. The review protocol was registered in the Open Science Framework. Results: a total of 27 studies were included, of which five were Guidelines and 22 were articles published in journals. There is a significant variety of disinfection methods for hubs and connectors. Chlorhexidine Gluconate, Isopropanol and Povidone-iodine were indicated for active disinfection; and Chlorhexidine Gluconate and Isopropanol, for passive disinfection. The disinfectant volume varied from 0.25 mL to 0.6 mL. Friction time in active disinfection ranged from five to 30 seconds, and contact time in passive disinfection varied from three minutes to seven days. The disinfectants' drying time was over five minutes. Conclusion: a variety of disinfection methods is verified, although with no consensus on the best indication. Studies that show the amount of disinfectant, pressure, friction and drying time are required. There is a need to conduct research studies with disinfection practices used in Brazil and randomized clinical trials.

KRAS and NRAS mutational analysis in plasma ctDNA from patients with metastatic colorectal cancer by real-time PCR and digital PCR.

PURPOSE: Mutations in the KRAS and NRAS (RAS) genes are negative predictors of response to anti-EGFR therapy in metastatic colorectal cancer (mCRC). The detection of mutations in circulating tumor DNA (ctDNA) has emerged as a less invasive strategy to assess the molecular profile of mCRC patients. We aimed to perform RAS mutational analysis in ctDNA from mCRC patients using BEAMing Digital PCR (OncoBEAM) and Idylla ctDNA qPCR and evaluate the concordance rate with RAS mutational status in tumor tissue and between these two methodologies with different limits of detection. METHODS: Blood samples were collected from 47 mCRC patients previously tested for RAS mutations in tumor tissue. DNA was extracted from plasma using the QIAamp Circulating Nucleic Acid Kit, and RAS mutation analysis was conducted using OncoBEAM RAS CRC and Idylla ctRAS assays. RESULTS: The overall agreement between tumor tissue and ctDNA analyses was 83% and 78.7% using the OncoBEAM and Idylla assays, respectively, with the concordance being 96.2% and 88.5% in naive treatment patients. The overall agreement between OncoBEAM and Idylla ctDNA analyses was 91.7%. CONCLUSIONS: Analysis of ctDNA is a viable strategy for clinical management of mCRC patients. Although the OncoBEAM assay sensitivity is somewhat higher, the fully automated Idylla platform also has good performance, while being cheaper and much less labor-intensive, for the detection of RAS mutations in plasma, either at diagnosis or after progression when considering anti-EGFR treatment rechallenge.

Involvement of companions in patient safety in pediatric and neonatal units: scope review.

OBJECTIVES: to describe scientific evidence on the involvement of companions in patient safety, from their own perspective and health professionals' perspective in neonatal and pediatric units. METHODS: scoping review carried out according to The Joanna Briggs Institute's recommendations, in eight databases, following the Preferred Reporting Items checklist for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist, between 2011 and 2021. RESULTS: the 13 studies included highlighted the importance of companions' involvement in patient safety and the prevention of adverse events. However, they pointed out failures in communication and weakness in the training of professionals, which were obstacles to their involvement. The strengthening of health education, multidisciplinary rounds and educational technologies were highlighted as strategies to expand the involvement of companions. FINAL CONSIDERATIONS: this study directs elements for health professionals and managers to rethink the companions' role in patient safety and development of collective strategies.

Cardiovascular characterization of the novel organic mononitrate NDIBP in rats.

Organic nitrates are widely used to restore endogenous nitric oxide (NO) levels reduced by endothelial nitric oxide synthase dysfunction. However, these drugs are associated with undesirable side effects, including tolerance. This study aims to investigate the cardiovascular effects of the new organic nitrate 1,3-diisobutoxypropan-2-yl nitrate (NDIBP). Specifically, we assessed its effects on blood pressure, vascular reactivity, acute toxicity, and the ability to induce tolerance. In vitro and ex vivo techniques showed that NDIBP released NO both in a cell-free system and in isolated mesenteric arteries preparations through a process catalyzed by xanthine oxidoreductase. NDIBP also evoked endothelium-independent vasorelaxation, which was significantly attenuated by 2-phenyl-4,4,5,5,-tetramethylimidazoline-1-oxyl 3-oxide (PTIO, 300 µM), a nitric oxide scavenger; 1-H-[1,2,4] oxadiazolo-[4,3-a]quinoxalin-1-one (ODQ, 10 µM), a soluble guanylyl cyclase inhibitor; tetraethylammonium (TEA, 3 mM), a potassium channel blocker; febuxostat (500 nM), a xanthine oxidase inhibitor; and proadifen (10 µM), an inhibitor of cytochrome P450 enzyme. Furthermore, this organic nitrate did not induce tolerance in isolated vessels and presented low toxicity following acute oral administration. In vivo changes on cardiovascular parameters were assessed using normotensive and renovascular hypertensive rats. NDIBP evoked a reduction of blood pressure that was significantly higher in hypertensive animals. Our results suggest that NDIBP acts as a NO donor, inducing blood pressure reduction without having the undesirable effects of tolerance. Those effects seem to be mediated by activation of NO-sGC-cGMP pathway and positive modulation of K+ channels in vascular smooth muscle.

Impact of high-fidelity simulation in pediatric nursing teaching: an experimental study / Efecto de la simulación clínica de alta fidelidad en la enseñanza de enfermería pediátrica: estudio experimental / O impacto da simulação clínica de alta fidelidade no ensino de enfermagem pediátrica: estudo experimental

ABSTRACT Objective: to assess the impact of high-fidelity clinical simulation on undergraduate teaching, specifically in the Pediatric Nursing area. Method: a quasi-experimental study of the pre- and post-test type, developed at three public Higher Educations Institutions (HEIs) in Brazil. The participants were 93 undergraduate Nursing students, enrolled in the Pediatric Nursing academic disciplines, and randomly allocated to the control or experimental groups. The data were collected in the first half of 2017, through a structured knowledge test and the Satisfaction with Simulated Clinical Experiences Scale. The experimental group received the usual intervention (participation in the theoretical and theoretical-practical activities offered in the disciplines) and the study intervention (high-fidelity clinical simulation); the control group only received the usual intervention. The data were analyzed by means of descriptive and analytical statistics. An explanatory model was prepared by means of multiple linear regression to assess the impact of simulation on teaching. Results: the mean difference between the knowledge pre- and post-tests was 4.04 points (p=0.0004) higher among the experimental group participants, indicating a greater increase in knowledge with the simulation. The participants from University A, who performed the simulation after the theoretical activities and before the theoretical-practical activities, obtained a higher mean difference between the knowledge pre- and post-tests (by 3.89 points, p=0.0075) than that of obtained by the participants from the other institutions. In relation to the satisfaction scale, high scores were achieved (mean=9.11±0.67). Conclusion: high-fidelity clinical simulation in Pediatrics contributed to increasing the Nursing students' knowledge and satisfaction levels.

RESUMEN Objetivo: evaluar el efecto de la simulación clínica de alta fidelidad en la carrera de grado del área de Enfermería Pediátrica. Método: estudio cuasi experimental del tipo pre y post test, desarrollado en tres instituciones públicas de enseñanza superior de Brasil. Participaron 93 estudiantes de la carrera de grado de Enfermería, inscriptos en las disciplinas académicas Enfermería Pediátrica y asignados aleatoriamente al grupo control o experimental. Los datos se recolectaron durante el primer semestre de 2017 por medio de una prueba de conocimiento estructurada y de la Escala de Satisfacción con las Experiencias Clínicas Simuladas. Al grupo experimental se le aplicó la intervención habitual (participación en las actividades teóricas y teórico-prácticas ofrecidas en las disciplinas) y la intervención del estudio (simulación clínica de alta fidelidad); el grupo control solamente recibió la intervención habitual. Los datos se analizaron por medio de estadística descriptiva y analítica. Para evaluar el efecto de la simulación en la enseñanza se elaboró un modelo explicativo por medio de regresión lineal múltiple. Resultados: la diferencia media entre el pre y el post test de conocimiento fue 4,04 puntos (p=0,0004) más alta entre los participantes del grupo experimental, lo que indica un mayor aumento en el conocimiento con la simulación. Los participantes de la Institución A - que realizaron la simulación después de las actividades teóricas y antes de las teórico-prácticas - obtuvieron una diferencia media más elevada entre el pre y el post-test de conocimiento (3,89 pontos más, p=0,0075) que la alcanzada por los participantes de las otras instituciones. En relación con la escala de satisfacción, las puntuaciones alcanzaron un nivel elevado (media=9,11±0,67). Conclusión: la simulación clínica de alta fidelidad en Pediatría contribuyó a mejorar los niveles de conocimiento y satisfacción de los estudiantes de Enfermería.
