Objetivo: Describir las características de los pacientes quemados usuarios de opioides e identificar los factores que predisponen a depresión respiratoria. Método: Transversal retrospectivo, en el que se analizaron 272 historiales de pacientes quemados internados de 2011 a 2013 en un Centro de Tratamiento de Quemados (CTQ). Se seleccionaron historiales completos de pacientes, con registro relleno de alta u óbito, periodo de internamiento mínimo de 48 horas, mayores de 18 años, usuarios de opioides por diferentes vías de administración, monitoreados por oximetría de pulso y sin empleo de prótesis de ventilación. Todos los episodios de depresión respiratoria se identificaron a través de cómo mínimo dos indicadores de entre los siguientes: la administración de Naloxone, registro de presión arterial inferior a 110/60mmHg, entubamiento orotraqueal, oximetría de pulso inferior a 90%, frecuencia respiratoria inferior a 10 irpm, necesidad de oferta de oxígeno e interrupción abrupta del opioide. Resultados: Este estudio identificó que el 28,58% de los pacientes quemados atendidos en una unidad de tratamiento de quemados presentaron depresión respiratoria. Predominaron en el grupo con depresión respiratoria pacientes jóvenes del sexo masculino, con mortalidad elevada, quemaduras de 2º y 3º grado fueron la mayoría, corroborando la mayoría de los estudios epidemiológicos acerca de las características de los pacientes quemados. Los factores predominantes para depresión respiratoria identificados en la población de pacientes quemados usuarios de opioides fueron insuficiencia renal aguda, etilismo, enfermedades cardiovasculares. Conclusión: El enfermero debe monitorear a todos los pacientes usuarios de opioides en relación a los parámetros de ventilación y nivel de coincidencia para prevenir e identificar precozmente sedación excesiva y depresión respiratoria, especialmente los pacientes en quienes se identifiquen dos o más factores de predisposición para DR.

La atención hospitalaria en el costo global de la atención de los pacientes en diálisis es muy importante. Este estudio se realizó con el fin de evaluar resultados posteriores a la implementación de un modelo de gestión de la enfermedad y cuidado coordinado en una red de diálisis en Colombia, evaluando los cambios específicos en las tasas de hospitalización de una cohorte de pacientes renales con dos años de seguimiento. El modelo se enfoca básicamente en mejorar la atención de los pacientes en diálisis protocolizando en el manejo de comorbilidades (diabetes, riesgo cardiovascular, patologías infecciosas) y en el cuidado coordinado entre el tratamiento ambulatorio y hospitalario de los pacientes en diálisis asegurando la continuidad en el proceso de atención de los pacientes. El Estudio observacional analítico de cohortes compuesto por 2 fases una primera cohorte histórica retrospectiva y una segunda con dos cohortes prospectivas, incluyó pacientes mayores de 18 años, con más de 90 días en diálisis, con al menos tres meses de intervención con el modelo de gestión de enfermedad en la red Renal Therapy Services (RTS®). En conclusión, la realización de este estudio, se pudo asociar a la reducción en la atención hospitalaria de pacientes en diálisis y a una menor mortalidad, modelos como este y otras soluciones para mejorar los desenlaces en salud en los pacientes en diálisis deben seguir siendo implementados para aliviar la carga de la enfermedad y reducir los costos de la atención en salud de esta población.

Background: Cardiovascular disease (CVD) is a common cause of morbidity and mortality in childhood chronic kidney disease (CKD). Left ventricular hypertrophy (LVH) is known to be one of the earliest events in CVD development. Left ventricular diastolic function (DF) is thought to be also impaired in children with CKD. Tissue Doppler imaging (TDI) provide an accurate measure of DF and is less load dependent than conventional ECHO. Aim: To evaluate the LV mass and the DF in a population of children with CKD. Methods: 37 patients, median age: 10.4 (3.3-19.8); underlying renal disease: hypo/dysplasia (N=28), nephronophthisis (N=4), Alport (N=2), ARPKD (N=3), were analyzed. Thirty-eight percent of the patients were on stage 1-2 of CKD, 38% on stage 3, 16% on stage 4. Three patients were on dialysis. The most frequent factors related to CVD in CKD have been studied. LVH has been defined as a left ventricular mass index (LVMI) more than 35.7 g/h2,7. Results: Twenty-five patients (81%) had a LVH. LVMI and diastolic function index (E’/A’) were significantly related to the glomerular filtration rate (p<0.003 and p<0.004). Moreover the LVMI was correlated with the phosphorus and the hemoglobin level (p<0.0001 and p<0.004). LVH was present since the first stages of CKD (58% of patients were on stages 1-2). Early-diastolic myocardial velocity was reduced in 73% of our patients. We didn’t find any correlation between LVH and systemic hypertension. Conclusion: ECHO evaluation with TDI is suggested also in children prior to dialysis and with a normal blood pressure. If LVH is diagnosed, a periodic follow-up is necessary with the treatment of the modifiable risk factors (hypertension, disturbances of calcium, phosphorus and PTH, anemia ).

INTRODUCTION. Late chronic allograft disfunction (CAD) is one of the more concerning issues in the management of patients (pts) with renal transplant (tx). Humoral immune response seems to play an important role in CAD pathogenesis. AIM OF THE STUDY. To identify the causes of late chronic allograft disfunction. METHODS. This study (march 2004-august 2011) enrolled pts who underwent renal biopsy (BR) because of CAD (increase of creatininemia (s-Cr) >30% and/or proteinuria >1g/day at least one year after tx). BR were classified according to 1997/2005 Banff classification. Histological evaluation of C4d (positive if >25%), glomerulitis, tubulitis, intimal arteritis, atrophy/fibrosis and arteriolar-hyalinosis were performed. Ab anti-HLA research at BR was an inclusion criteria. Pts were divided into two groups: with or without transplant glomerulopathy (CTG). RESULTS. Evaluated BR: 93/109. BR indication: impaired s-Cr (52/93), proteinuria (23/93), both (18/93). Time Tx-BR: 7.4±6.3 yrs; s-Cr at BR: 2.7±1.4 mg/dl. CTG group(n=49) not-CTG group(n=44) p Time tx-BR (yrs) 9.3±6.7 5.3±5.2 0.002 Follow-up post-BR (yrs) 2.7±1.8 4.1±1.4 0.0001 s-Cr at BR (mg/dl) 2.9±1.3 2.4±1.5 NS Rate (%) of pts: Proteinuria at BR 61% 25% 0.0004 C4d+ 84% 25% <0.0001 Ab anti-HLA+ 71% 30% 0.0001 C4d+ and/or Ab antiHLA 92% 43% 0.0001 Glomerulitis 76% 16% <0.0001 Tubulitis 6% 32% 0.0014 Intimal arteritis 18% 0% 0.002 Arteriolar hyalinosis 65% 50% NS Atrophy/fibrosis 80% 77% NS Graft survival 45% 86% 0.00005 Histological Diagnosis: CTG group (n=49:Chronic rejection 94%;IgA recurrence + humoral activity 4%;IIA acute rejection + humoral activity 2%. Not-CTG group (n=44: GN recurrence 27%;IF/TA 23%; acute rejection 23%;BKV nephritis 9%; mild not specific alterations 18%. CONCLUSIONS: CTG is the morphological lesion mainly related to CAD. In the 92% of the cases it is associated with markers of immunological activity. It causes graft failure within five years after diagnosis in 55% of pts.

Negli ultimi anni si è assistito ad un miglioramento della qualità di vita dei piccoli animali che, oltre ad aumentarne l'aspettativa di vita, ha determinato un aumento della frequenza di patologie associate all'età medio-avanzata, quali le patologie renali croniche. Il presente studio si fonda sulla necessità, sempre più sentita nella pratica clinica veterinaria, di poter fornire al proprietario del paziente affetto da CKD, una serie di parametri che, oltre a fungere da target terapeutico, possano aiutare a comprenderne la prognosi. Lo studio ha valutato una popolazione di cani affetti da CKD e ne ha seguito o ricostruito il follow-up, per tutto il periodo di sopravvivenza fino al momento dell’exitus. Di tali soggetti sono stati raccolti dati relativi ad anamnesi, esame clinico, misurazione della pressione arteriosa, diagnostica per immagini, esami ematochimici, analisi delle urine ed eventuale esame istologico renale. È stato possibile individuare alcuni importanti fattori prognostici per la sopravvivenza in pazienti con CKD. Oltre a fattori ben noti in letteratura, come ad esempio elevati valori di creatinina e fosforo, o la presenza di proteinuria, è stato possibile anche evidenziare il ruolo prognostico negativo di alcuni parametri meno noti, ed in particolare delle proteine di fase acuta positive e negative, e del rapporto albumina/globuline. Una possibile spiegazione del valore prognostico di tali parametri risiede nel ruolo prognostico negativo dell’infiammazione nel paziente con CKD: tale ruolo è stato suggerito e dimostrato nell’uomo e avrebbe alla base numerosi possibili meccanismi (sviluppo di anemia, complicazioni gastroenteriche, neoplasie, etc.), ma dati analoghi sono mancanti in medicina veterinaria. Una seconda possibile spiegazione risiede nel fatto che potenzialmente i livelli delle proteine di fase acuta possono essere influenzati dalla presenza di proteinuria nel paziente con CKD e di conseguenza potrebbero essere una conferma di come la proteinuria influenzi negativamente l'outcome.

End-stage renal failure is a life-threatening condition, often treated with home-based peritoneal dialysis (PD). PD is a demanding regimen, and the patients who practise it must make numerous lifestyle changes and learn complicated biomedical techniques. In our experience, the renal nurses who provide mostPDeducation frequently express concerns that patient compliance with their teaching is poor. These concerns are mirrored in the renal literature. It has been argued that the perceived failure of health professionals to improve compliance rates with PD regimens is because ‘compliance’ itself has never been adequately conceptualized or defined; thus, it is difficult to operationalize and quantify. This paper examines how a group of Australian renal nurses construct patient compliance with PD therapy. These empirical data illuminate how PD compliance operates in one practice setting; how it is characterized by multiple and often competing energies; and how ultimately it might be pointless to try to tame ‘compliance’ through rigid definitions and measurement, or to rigidly enforce it in PD patients. The energies involved are too fractious and might be better spent, as many of the more experienced nurses in this study argue, in augmenting the energies that do work well together to improve patient outcomes.

The high levels of end-stage renal disease among Indigenous Australians, particularly in remote areas of the country, are a serious public health concern. The magnitude of the problem is reflected in figures from the Australian and New Zealand Transplant and Dialysis Registry that show that Indigenous Australians experience end-stage renal disease at a rate almost 9–10 times higher than other non-Indigenous Australians. A majority of Indigenous Australians have to relocate to receive appropriate renal dialysis treatment. In some Australian states, renal treatment is based on self-care dialysis which allows those Indigenous Australians to be treated back in their community. Evidence clearly shows that reuniting renal patients with community and family improves overall health and well-being for those Indigenous Australians. With the appropriate resources, training, and support, self-care management of renal dialysis treatment is an effective way for Indigenous people with end-stage renal failure to be treated at home. In this context, the study was used to gain insight and further understanding of the impact that end-stage renal disease and renal dialysis treatment has had on the lives of Indigenous community members. The study findings are from 14 individually interviewed people from South East Queensland. Data from the interviews were analysed using a combination of thematic and content analysis. The study methodology was based on qualitative data principles where the Indigenous community members were able to share their experiences and journeys living with end-stage renal disease. Many of the experiences and understanding closely relate to the renal disease pattern and the treatment with other outside influences, such as social, cultural, and environmental influences, all having an equal impact. Each community member’s experience with end-stage renal disease is unique; some manage with family and medical support, while others try to manage independently. From the study, community members who managed their renal dialysis treatment independently were much more aware of their renal health status. The study provides recommendations towards a model of care to improve the health and well-being is based on self-care and self-determination principles.

Background: The transmission of hemorrhagic fever with renal syndrome (HFRS) is influenced by climatic variables. However, few studies have examined the quantitative relationship between climate variation and HFRS transmission. ---------- Objective: We examined the potential impact of climate variability on HFRS transmission and developed climate-based forecasting models for HFRS in northeastern China. ---------- Methods: We obtained data on monthly counts of reported HFRS cases in Elunchun and Molidawahaner counties for 1997–2007 from the Inner Mongolia Center for Disease Control and Prevention and climate data from the Chinese Bureau of Meteorology. Cross-correlations assessed crude associations between climate variables, including rainfall, land surface temperature (LST), relative humidity (RH), and the multivariate El Niño Southern Oscillation (ENSO) index (MEI) and monthly HFRS cases over a range of lags. We used time-series Poisson regression models to examine the independent contribution of climatic variables to HFRS transmission. ----------- Results: Cross-correlation analyses showed that rainfall, LST, RH, and MEI were significantly associated with monthly HFRS cases with lags of 3–5 months in both study areas. The results of Poisson regression indicated that after controlling for the autocorrelation, seasonality, and long-term trend, rainfall, LST, RH, and MEI with lags of 3–5 months were associated with HFRS in both study areas. The final model had good accuracy in forecasting the occurrence of HFRS. ---------- Conclusions: Climate variability plays a significant role in HFRS transmission in northeastern China. The model developed in this study has implications for HFRS control and prevention.

The very act of withdrawing dialysis places renal nurses in a unique practice setting requiring a sudden shift in care delivery from one of providing Ife-sustaining, active treatment to that of palliation. The impact of this act on the renal nurse remains largely invisible. Minimal research has been conducted that explores the significant issues and challenges that exist for renal nurses in the delivery of palliation following withdrawal of dialysis treatment. This paper attempts to highlight the issues and challenges that do exist for renal nurses in providing palliation and the subsequent lack of available research knowledge to inform practice in the renal setting. It recommends further research be conducted into the renal setting so as to inform the development of appropriate education to support renal nurses practice in the future.

Aims. This article is a report of a study done to identify how renal nurses experience information about renal care and the information practices that they used to support everyday practice. Background. What counts as nursing knowledge remains a contested area in the discipline yet little research has been undertaken. Information practice encompasses a range of activities such as seeking, evaluation and sharing of information. The ability to make informed judgement is dependent on nurses being able to identify relevant sources of information that inform their practice and those sources of information may enable the identification of what knowledge is important to nursing practice. Method. The study was philosophically framed from a practice perspective and informed by Habermas and Schatzki; it employed qualitative research techniques. Using purposive sampling six registered nurses working in two regional renal units were interviewed during 2009 and data was thematically analysed. Findings. The information practices of renal nurses involved mapping an information landscape in which they drew on information obtained from epistemic, social and corporeal sources. They also used coupling, a process of drawing together information from a range of sources, to enable them to practice. Conclusion. Exploring how nurses engage with information, and the role the information plays in situating and enacting epistemic, social and corporeal knowledge into everyday nursing practice is instructive because it indicates that nurses must engage with all three modalities in order to perform effectively, efficiently and holistically in the context of patient care. © 2011 The Authors.

The purpose of this article is to present lessons learnt by nurses when conducting research to encourage colleagues to ask good clinical research questions. This is accomplished by presenting a study designed to challenge current practice which included research flaws. The longstanding practice of weighing renal patients at 0600 hours and then again prior to receiving haemodialysis was examined. Nurses believed that performing the assessment twice, often within a few hours, was unnecessary and that patients were angry when woken to be weighed. An observational study with convenience sampling collected data from 46 individuals requiring haemodialysis, who were repeatedly sampled to provide 139 episodes of data. Although the research hypotheses were rejected, invaluable experience was gained, with research and clinical practice lessons learnt, along with surprising findings.

There are many reasons to look back in time such as trying to learn from the past or to avoid repeating it. History also tells us where we have come from and how this has shaped the current environment in which we live, socialise and work. Renal health care has also been shaped by the past, and insights from the past can help us to face the challenges of the present, and in turn to see how the future might be.
