Enfermedad oncoproliferativa en el receptor de trasplante renal. Nuestra experiencia / Oncoproliferative diseases in kidney transplant recipients. Our experience

Introducción: El cáncer conlleva a una mortalidad de hasta 12 % en los pacientes trasplantados, y se considera la tercera causa de morbilidad y mortalidad en los receptores, al ser estos susceptibles a desarrollar enfermedades oncoproliferativas, a largo plazo. Objetivo: Describir la incidencia de neoplasias en receptores de trasplante renal. Métodos: Estudio descriptivo y longitudinal que incluyó 15 receptores de trasplante renal funcionante, con diagnóstico de neoplasias malignas en diferentes localizaciones en el período comprendido entre enero de 2017 y junio de 2023 en el servicio de Nefrología del Hospital Universitario Clínico-Quirúrgico «Arnaldo Milián Castro» de Santa Clara, Villa Clara. Resultados: Predominaron los hombres y el color de piel blanca: 53,3 % y 73,3% respectivamente, con tiempo postrasplante superior a tres años en 12 pacientes (80 %). El antecedente de exposición al citomegalovirus representó el 80 %; la infección bacteriana de la vía respiratoria y digestiva fue la más frecuente. Conclusiones: La neoplasia intraepitelial cervicouterina, la de colon con metástasis hepática y las cerebrales resultaron las más frecuentes, y fueron tratadas con cirugía, quimioterapias o ambas, según los criterios quirúrgicos en cada caso; no obstante, la mortalidad fue elevada. La estirpe neoplásica preponderante fue la neoplasia intraepitelial cervical en un 26,6 %. La mortalidad fue alta y la supervivencia fue menor en el sexo masculino, sin rebasar los dos años posteriores al diagnóstico.

Introduction: cancer entails a mortality of up to 12 % in transplanted patients and is considered the third leading cause of morbidity and mortality in recipients who are susceptible to develop oncoproliferative diseases in the long term. Objective: to describe the incidence of neoplasms in renal transplant recipients. Methods: we carried out a descriptive and longitudinal study including 15 functioning renal transplant recipients who were diagnosed with malignant neoplasms in different locations in the Nephrology service at "Arnaldo Milián Castro" Clinical and Surgical University Hospital in Santa Clara, Villa Clara between January 2017 and June 2023. Results: males and white skin color predominated: 53.3 % and 73.3% respectively, with post-transplant time greater than three years in 12 patients (80 %). The history of cytomegalovirus exposure represented 80 %; bacterial infection of the respiratory and digestive tracts was the most frequent. Conclusions: cervicouterine intraepithelial neoplasia, colon cancer with liver and brain metastases were the most frequent and treated with surgery chemotherapies or both according to the surgical criteria in each case; however, mortality was elevated. Cervical intraepithelial neoplasia predominated in a 26.6 %. Mortality was high and survival was lower in males, without exceeding two years after the diagnosis.

Indicación, realización y resultado del cateterismo de venas adrenales en pacientes con hiperaldosteronismo primario / Indication, performance and outcomes of adrenal vein sampling in patients with primary hyperaldosteronism

El hiperaldosteronismo primario (HAP) es una causa importante de hipertensión arterial (HTA) secundaria. El estudio del mismo precisa de una alta sospecha clínica, además de un estudio hormonal que confirme la hipersecreción hormonal. Es importante iniciar el tratamiento adecuado una vez se confirma el diagnóstico, y para ello es preciso demostrar si la hipersecreción hormonal es unilateral (pacientes que podrían ser tributarios a tratamiento quirúrgico) o bilateral (pacientes que son tributarios a tratamiento únicamente farmacológico). En el Hospital del Mar desde el año 2016 existe un equipo de trabajo multidisciplinar en el que participan nefrólogos, endocrinólogos, radiólogos y cirujanos para evaluar los casos con sospecha de hiperaldosteronismo y consensuar el mejor abordaje diagnóstico-terapéutico de estos pacientes, incluyendo la necesidad de cateterismo venoso adrenal, que es una técnica que en los últimos años se ha erigido como gold standard para el estudio del HAP. En el presente estudio recogemos la experiencia de nuestro centro en la realización de cateterismo venoso adrenal y en la utilidad de este para el manejo de tales pacientes (AU)

Primary hyperaldosteronism (PAH) is an important cause of secondary hypertension (HTN). The study of the same requires a high clinical suspicion in addition to a hormonal study that confirms hormonal hypersecretion. It is important to start the appropriate treatment once the diagnosis is confirmed, and for this is necessary to demonstrate whether the hormonal hypersecretion is unilateral (patients who could be candidates for surgical treatment) or bilateral (patients who are candidates for pharmacological treatment only). At the Hospital del Mar since 2016 there has been a multidisciplinary work team in which Nephrologists, Endocrinologists, Radiologists and Surgeons participate to evaluate cases with suspected hyperaldosteronism and agree on the best diagnostic-therapeutic approach for these patients, including the need for adrenal vein sampling, which is a technique that in recent years has become the gold standard for the study of PAH. In the present study we collect the experience of our center in performing adrenal vein catheterization and its usefulness for the management of these patients (AU)

Evaluation of the use of a Renal Health application by kidney transplant recipients / Avaliação do uso do aplicativo Renal Health por transplantados renais / Evaluación del uso de la Aplicación Renal Health por parte de los receptores de trasplante renal

Abstract Objective: to evaluate the use of a renal health application by kidney transplant recipients. Method: a retrospective, observational study with a sample composed of individuals registered in the kidney transplant section of the application from July of 2018 to April of 2021. Demographic data, data entry, time of use, weight, blood pressure, blood glucose, creatinine, medication schedules, appointments, and tests were the variables collected. Descriptive analysis of the data was performed. Results: eight hundred and twenty-three downloads of the application were identified, and 12.3% of those were registered as kidney transplant recipients, the majority from southeastern Brazil (44.9%), 36±11 years old, and female (59.1%). Of the sample, 35.1% entered information such as creatinine (62%), weight (58.2%), and blood pressure (51.8%). Most used the application for one day (63.3%) and 13.9% for more than one hundred days. Those who used it for more than one day (36.7%) recorded weight (69%), medication intake (65.5%) and creatinine (62%), and scheduled appointments (69%). Conclusion: the kidney transplant recipient section of the Renal Health application generated interest in the young population, but showed low adherence throughout the assessed months. These results offer a relevant perspective on the implementation of mHealth technologies in kidney transplantation.

[Epidemiology of glomerular disease: report from a third-level center]. / Epidemiología de la enfermedad glomerular: reporte de un centro de tercer nivel.

Background: Renal biopsy has become one of the pillars of nephrology practice, being a very important tool in the diagnostic approach of any nephrology center, since it contributes to the identification and adequate management of glomerular diseases, which represent the third cause of chronic kidney disease in the world. In Mexico there are few reports on the epidemiology of glomerular diseases; therefore, it is important to carry out this type of study. Objective: To identify which are the main glomerulopathies reported in our center, Determine the most prevalent glomerular syndrome according to the reported glomerulopathy, and identify the main complications after percutaneous renal biopsy. Material and methods: A retrolective cross-sectional study which included patients who underwent percutaneous biopsy of the native kidney from August 2020 to August 2022; we obtained information from the service's database. Results: 89 biopsy reports were analyzed, out of which 66.29% corresponded to the female gender and 32.70% to the male gender. The average age was 37.6 ± 12.86 years. The most frequent primary glomerulopathy was focal segmental glomerulosclerosis (FSG) in 22.5%, followed by membranous nephropathy in 7.9%. The most frequent secondary glomerulopathy was lupus nephropathy in 42.7%. Nephrotic syndrome occurred in 43.85% of cases. 89% of the patients did not present post-biopsy complications. Conclusions: FSG is the most common primary glomerulopathy. Nephrotic syndrome was the main indication for renal biopsy. The vast majority of patients did not present complications, so we can consider it to be a safe and above all useful procedure for the diagnosis of glomerular diseases.

Introducción: la biopsia renal es una herramienta muy importante en el abordaje diagnóstico de cualquier centro nefrológico, pues contribuye a identificar y manejar adecuadamente las enfermedades glomerulares, que representan la tercera causa de enfermedad renal crónica en el mundo. En México hay pocos reportes de la epidemiología de las enfermedades glomerulares, por lo que es importante hacer este tipo de estudios. Objetivo: identificar las principales glomerulopatías reportadas en nuestro centro. Material y métodos: estudio transversal retrolectivo que incluyó reportes histopatológicos de los pacientes a los que se les realizó biopsia percutánea de riñón nativo de agosto de 2020 a agosto de 2022; toda la información se obtuvo del expediente clínico. Resultados: se analizaron 89 reportes de biopsias, de las cuales 66.29% correspondían al género femenino y 33.7% al género masculino. La edad promedio fue 37.6 ± 12.86 años. La glomerulopatía primaria más frecuente fue la glomeruloesclerosis focal y segmentaria (GEFyS) en 22.5%, seguida de la nefropatía membranosa 7.9%. La glomerulopatía secundaria más frecuente fue la nefropatía lúpica, con 42.7%. El síndrome nefrótico se presentó en el 43.85% de los casos. El 89% de los pacientes no presentaron complicaciones posteriores a la biopsia. Conclusiones: la GEFyS es la glomerulopatía primaria más frecuente. El síndrome nefrótico fue la principal indicación para realizar biopsia renal. La gran mayoría de pacientes no presentaron complicaciones, por lo que podemos considerar que la biopsia renal es un procedimiento seguro y sobre todo útil para el diagnóstico de las enfermedades glomerulares.

[Mortality in patients with COVID-19 and acute kidney injury on hemodialysis]. / Mortalidad en pacientes con COVID-19 y lesión renal aguda en hemodiálisis.

Background: A high in-hospital mortality has been identified in patients with COVID-19 who develop acute kidney injury, particularly in those who received renal replacement therapy. In our country there are few studies up until now that report the proportion of deaths in this group of patients. Objective: To identify the proportion of deaths in patients with COVID-19 who developed acute kidney injury and required hemodialysis. Material and methods: an observational, descriptive, cross-sectional, retrospective study was carried out and the total population was studied. It included patients over 18 years of age who required dialysis, who received one or more sessions of conventional hemodialysis. The data were obtained from the electronic file and the registry of the hemodialysis unit. For the descriptive analysis, measures of central tendency were used and the proportion of deaths in patients with COVID-19 was calculated. Results: The study population was made up of 40 patients; the proportion of deaths was 86.1%. The average number of days elapsed from admission to the development of acute kidney injury and dialysis requirement was 5.2 days and the average number of hemodialysis sessions received was 1.7 sessions. Conclusions: In this study it was documented a high proportion of deaths in patients with COVID-19 who developed acute kidney injury and required renal replacement therapy, which coincides with similar studies reported internationally.

[Sleep quality in patients with chronic kidney disease on hemodialysis]. / Calidad del sueño en pacientes con enfermedad renal crónica en hemodiálisis.

Background: Chronic kidney disease (CKD) is a serious condition that impairs sleep quality, which compromises quality of life, cardiovascular function and increases the risk of mortality; however, limited information is available on sleep quality in hemodialysis (HD) patients. Objective: To determine the sleep quality in patients with CKD on renal replacement therapy with HD. Material and methods: Cross-sectional analytical study. The population included patients with CKD on HD, either sex, who answered the Pittsburgh questionnaire in a tertiary hospital. A 19-item self-administered survey was applied, assessing 7 components of sleep quality, where overall scores ≤ 5 and > 5 indicated respectively good and poor sleep quality. Socio-demographic, anthropometric, self-reported lifestyle and CKD history-related characteristics were assessed. Results: A total of 83 patients were included with a mean age of 45.3 (15.9), 63% (52) were male and 37% (31) female; of these, 63% (52) had poor sleep quality and 37% (31) had good sleep quality. Conclusion: Sleep quality is poor in patients with CKD on renal replacement therapy with HD. Variables influencing sleep quality are age, occupation, body mass index, sleep duration, and use of hypnotic medications. Therefore, HD patients should be evaluated to detect sleep problems in order to develop strategies to improve their sleep quality.

Introducción: la enfermedad renal crónica (ERC) es una condición grave que deteriora la calidad del sueño, lo que compromete la calidad de vida, la función cardiovascular y eleva el riesgo de mortalidad; sin embargo, es limitada la información disponible sobre la calidad del sueño en población con hemodiálisis (HD). Objetivo: determinar la calidad del sueño en los pacientes con ERC en terapia de sustitución renal con HD. Material y métodos: estudio transversal analítico. La población incluyó pacientes con ERC en HD, de cualquier sexo, que respondieron el Cuestionario de Pittsburgh en un hospital de tercer nivel. Se aplicó una encuesta autoadministrada de 19 elementos, que evalúa 7 componentes de la calidad del sueño. Los puntajes globales ≤ 5 y > 5 indicaron respectivamente una buena y mala calidad del sueño. Se evaluaron características sociodemográficas, antropométricas, el autorreporte de estilos de vida y las relacionadas con la historia de ERC. Resultados: se incluyeron un total de 83 pacientes con media de edad de 45.3 (15.9); 63% (52) fueron hombres y 37% (31) mujeres; de ellos, 63% (52) tuvieron mala calidad del sueño y 37% (31) tuvo buena calidad del sueño. Conclusión: la calidad del sueño es mala en los pacientes con ERC en terapia de sustitución renal con HD. Las variables que influyen en la calidad de sueño son la edad, ocupación, índice de masa corporal, duración del sueño y uso de medicamentos hipnóticos. Por tanto, los pacientes en HD deben ser evaluados para detectar problemas del sueño a fin de desarrollar estrategias para mejorar su calidad del sueño.

Indication, performance and outcomes of adrenal vein sampling in patients with primary hyperaldosteronism.

Primary hyperaldosteronism (PAH) is an important cause of secondary hypertension (HTN). The study of the same requires a high clinical suspicion in addition to a hormonal study that confirms hormonal hypersecretion. It is important to start the appropriate treatment once the diagnosis is confirmed, and for this is necessary to demonstrate whether the hormonal hypersecretion is unilateral (patients who could be candidates for surgical treatment) or bilateral (patients who are candidates for pharmacological treatment only). At the Hospital del Mar since 2016 there has been a multidisciplinary work team in which Nephrologists, Endocrinologists, Radiologists and Surgeons participate to evaluate cases with suspected hyperaldosteronism and agree on the best diagnostic-therapeutic approach for these patients, including the need for adrenal vein sampling, which is a technique that in recent years has become the gold standard for the study of PAH. In the present study we collect the experience of our centre in performing AVC and its usefulness for the management of these patients.

Objective: To identify the evidence available in the literature about nursing interventions in the face of complications inherent to hemodialysis treatment. Methodology: This is an integrative review of the literature through searches in the PubMed databases; VHL and Scopus in April 2023. The guiding question was established: "What is the evidence available in the literature about nursing interventions in the face of complications presented by patients submitted to hemodialysis?" Systematic review protocols or meta-analysis and incomplete studies were excluded, which do not make reference to the purpose of the research. Results: In the search, 09 studies were selected for this review, which met the eligibility criteria. It was evidenced in the literature that the implementation of specific preventive measures during the HD process can significantly reduce the incidence of complications in patients undergoing this procedure. The most common complications in patients undergoing treatment are: nausea, headache, hypotension, cramps, clotting, and infections. Evidence shows that early identification and management of these complications can improve clinical outcomes and patients' quality of life. Nursing care such as frequent monitoring of vital signs, proper hygiene, correct drug administration, self-care guidelines, and innovative measures are important to ensure patient safety during treatment. Professionals need to be aware of the complications associated with HD so that they are able to intervene in the right way. Final considerations: Studies have shown that it is essential that healthcare professionals involved in care, especially nurses, are able to intervene in possible complications during therapy in order to minimize the impacts on patient health.

Processo de ensino-aprendizagem em nefrologia: uma revisão integrativa / Teaching-Learning Process in Nephrology: An Integrative Review

Resumo: Introdução: A redução da procura pelos Programas de Residência Médica em Nefrologia na última década é um assunto que vem ganhando relevância, notadamente nas discussões suscitadas pelas sociedades científicas e associações médicas por todo o mundo. Constata-se que há falta de interesse pela especialidade desencadeado por processos de ensino-aprendizagem inadequados no sentido de gerar interesse dos graduandos. Diante desse cenário, é fundamental compreender quais são os fatores que influenciam o processo de ensino-aprendizagem na nefrologia durante a graduação. Objetivo: Este estudo teve como objetivo analisar as estratégias de ensino-aprendizagem em nefrologia e seus resultados durante a graduação em Medicina. Método: Foi realizada uma revisão integrativa de artigos publicados em inglês, espanhol e português sobre o ensino de nefrologia na graduação em Medicina, com busca em quatro bases de dados (PubMed, ERIC, SciELO e Lilacs). Usamos as seguintes palavras-chave em nossas pesquisas: "educação médica", "estudantes de medicina", "nefrologia", "métodos de ensino" (em português), "medical education", "medical students", "nephrology" e "teaching methods" (em inglês) e "educación médica", "estudiantes de medicina", "nefrología" e "métodos de enseñanza" (em espanhol). Resultado: Observou-se um papel relevante do uso de metodologias ativas nos processos de ensino-aprendizagem como uma ferramenta promissora para ampliar o interesse dos estudantes pelo tema. Além disso, constatou-se que uma parcela dos educadores médicos envolvidos com o ensino da nefrologia é, na realidade, composta de não nefrologistas. Por fim, percebe-se um papel do uso de ferramentas on-line como estratégia para ampliar o interesse dos estudantes pela disciplina. Conclusão: Falta rigor no desenho dos estudos sobre a formação do estudante de Medicina em nefrologia, o que não permite aferir resultados precisos sobre o impacto das metodologias de ensino-aprendizagem. Estudos controlados randomizados bem desenhados, bem como o uso de estudos de coorte comparando metodologias de ensino-aprendizagem, são necessários para avaliar efetivamente as técnicas educacionais introduzidas nos currículos das escolas médicas.

Abstract: Introduction: The reduced demand for Medical Residency Programs in Nephrology in the last decade is a subject that has been gaining relevance, notably in discussions raised by scientific societies and medical associations around the world. It appears that there is a lack of interest in the specialty, triggered by teaching-learning processes that are inadequate to generate interest among undergraduates. Given this scenario, it is essential to understand which factors influence the teaching-learning process in Nephrology during undergraduate training. Objective: To analyze teaching-learning strategies in nephrology and their results during undergraduate medical training. Method: An integrative review of articles published in English, Spanish and Portuguese on teaching of nephrology in undergraduate medicine was carried out, searching four databases (PubMed, ERIC, SciELO and Lilacs). We used the following keywords in our searches: "medical education", "medical students", "nephrology", "teaching methods", "medical education", "medical students", "nephrology" and "teaching methods" (in English) and "educational medicine", "medicine students", "nephrology" and "metodos de enseñanza" (in Spanish). Results: A relevant role was observed in the use of active teaching-learning methodologies as a promising tool to increase student interest in the subject. In addition, it was found that a portion of medical educators involved in the teaching of Nephrology are, in fact, not nephrologists. Finally, there is a role for the use of online tools as a strategy to increase student interest in the discipline. Conclusion: There is a lack of rigor in the design of studies on the training of medical students in nephrology, which does not allow for accurate results on the impact of teaching-learning methodologies. Well-designed randomized controlled trials, as well as the use of cohort studies comparing teaching-learning methodologies, are needed to assess the effectiveness of educational techniques introduced in medical school curricula.

La era del big data: análisis del lenguaje natural mediante la aplicación de folksonomía / The big data era: The usefulness of folksonomy for natural language processing

Antecedentes y objetivo: Gran parte de la información médica que se deriva de la práctica clínica habitual queda recogida en forma de lenguaje natural en los informes médicos. Clásicamente, la extracción de información clínica para su posterior análisis a partir de los informes médicos requiere de la lectura y revisión manual de cada uno de ellos con la consiguiente inversión de tiempo. El objetivo de este proyecto piloto ha sido evaluar la utilidad de la folksonomía para la extracción y análisis rápido de los datos que contienen los informes médicos. Material y métodos: En este proyecto piloto hemos utilizado la folksonomía para el análisis y la rápida extracción de datos de 1.631 informes médicos de alta de hospitalización del Servicio de Nefrología del Hospital del Mar sin necesidad de crear una base de datos estructurada previamente. Resultados: A partir de determinadas preguntas sobre la práctica médica habitual (tratamiento hipoglicemiante de los pacientes diabéticos, tratamiento antihipertensivo y manejo de los inhibidores del sistema renina angiotensina durante el ingreso en nefrología y análisis de datos relacionados con la esfera emocional de los pacientes renales) la herramienta ha permitido estructurar y analizar la información contenida en texto libre en los informes de alta. Conclusiones: La aplicación de folksonomía a los informes médicos nos permite transformar la información contenida en lenguaje natural en una serie de datos estructurados y analizables de manera automática sin necesidad de proceder a la revisión manual de los mismos. (AU)

Background: A huge amount of clinical data is daily generated and it is usually filed in clinical reports as natural language. Data extraction and further analysis requires reading and manual review of each report, which is a time consuming process. With the aim to test folksonomy to quickly obtain and analyze the information contained in medial reports we set up this study. Methods and objectives:We have used folksonomy to quickly obtain and analyse data from 1631 discharge clinical reports from Nephrology Department of Hospital del Mar, without the need to create an structured database. Results: After posing some questions related to daily clinical practice (hypoglycaemic drugs used in diabetic patients, antihypertensive drugs and the use of renin angiotensin blockers during hospitalisation in the nephrology department and data related to emotional environment of patients with chronic kidney disease) this tool has allowed the conversion of unstructured information in natural language into a structured pool of data for its further analysis. Conclusions: Folksonomy allows the conversion of the information contained in clinical reports as natural language into a pool of structured data which can be further easily analysed without the need of the classical manual review of the reports.

Lipid profile of patients treated with evolocumab in Spanish hospital nephrology units (RETOSS NEFRO).

BACKGROUND AND OBJECTIVE: To describe the clinical characteristics, the reasons for initiating therapy and the effects of treatment in the initial phase of evolocumab availability in the Nephrology Units of Spain. MATERIAL AND METHODS: Retrospective, observational and multicentric study that included patients initiating treatment with evolocumab (from February 2016 to August 2018), in 15 Nephrology Units in Spain. The demographic and clinical characteristics of the patients, the lipid lowering treatment and the evolution of the lipid profiles between 24 weeks pre-initiation and 12±4 weeks post-initiation of evolocumab were reviewed. RESULTS: 60 patients were enrolled: 53.3% women; mean (SD) age, 56.9 (12.8) years, 45.0% with familial hypercholesterolemia (FH) (5.0% homozygous and 40.0% heterozygous) and 65.0% with atherosclerotic cardiovascular disease. The mean (SD) eGFR was 62.6 (30.0) ml/min/1.73m2 (51.7% of patients had eGFR <60ml/min/1.73m2 [CKD stage>2]), 50.0% had proteinuria (>300mg/g) and 10.0% had nephrotic syndrome. Other CV risk factors were hypertension (75.0%), diabetes (25.0%), and smoking (21.7%). A 40.0% of patients were statin intolerant. At evolocumab initiation, 41.7% of patients were on a high intensity statin, 18.3% on moderate intensity statin and 50.0% were receiving ezetimibe. Mean (SD) LDL-c at evolocumab initiation was 179.7 (62.9) mg/dL (53.4% of patients with LDL-c ≥160mg/dL and 29.3% ≥190mg/dL). After 12 weeks, evolocumab resulted in LDL-c reductions of 60.1%. At week 12, 90.0% of patients reached LDL-c levels <100mg/dL, 70.0% <70mg/dL, and 55.0% <55mg/dL, while mean eGFR levels and statin use remained stable. CONCLUSION: In Nephrology Units of Spain, evolocumab was predominantly prescribed in patients with FH, chronic renal disease (CRD>2) and secondary prevention, with LDL-c levels above those recommended by the guidelines. Evolocumab used in clinical practice significantly reduced the LDL-c levels in all patients included in the study.

Bienestar espiritual en pacientes de servicios de oncología y hemodiálisis de dos centros de referencia

RESUMEN Introducción: la espiritualidad es un concepto muy amplio para la humanidad, su consenso para los diversos grupos se encuentra en estudio permanente. La importancia de introducir su abordaje en la salud integral del paciente es cada vez más significativa en la práctica médica. Objetivos: validar la escala MLQ de Steger de bienestar espiritual en idioma guaraní y evaluar el bienestar espiritual en pacientes de los servicios de oncología y hemodiálisis de dos centros de referencia. Métodos: la población enfocada fueron los pacientes en tratamiento oncológico y en diálisis de los servicios de oncología del Hospital de Clínicas (San Lorenzo) y de hemodiálisis del Sanatorio Español-NefroServ (Asunción) durante los meses de mayo, junio y julio de 2021. Se utilizó como instrumento la escala MLQ de Steger. El cuestionario evalúa dos dimensiones del significado de la vida utilizando 10 elementos clasificados en una escala de siete puntos. Se respetaron los aspectos éticos de la investigación en humanos. Resultados: se realizaron 107 cuestionarios, siendo 54 mujeres y 53 varones, 64 fueron tomados en el servicio de hemodiálisis y 41 en el servicio de oncología, 42 fueron realizados en guaraní y 65 en español, según preferencia del encuestado. El promedio de edad de la muestra fue 54,6 ± 14 años. De los encuestados, 11,2% (12) tenían formación primaria incompleta, 25,2% (27) primaria completa, 14,01% (15) secundaria incompleta, 13,08% (14) secundaria, 25,2% (27) terciario y 11,2% (12) no respondieron a esta pregunta. En relación con la religión, 99 manifestaron profesar la religión católica (92,5%). Se utilizó la medición de confiabilidad alfa de Cronbach para medir el grado de fiabilidad de la escala realizada en idioma guaraní, arrojando un valor de 0,87 (alta confiabilidad). Conclusión: se ha logrado probar la validez del instrumento en el idioma guaraní para la comunidad paraguaya guaraní-parlante. Además, se han observado las tendencias en términos de medición del bienestar espiritual entre las muestras estudiadas y sus diferentes perfiles, lo que permite un abordaje más integral en el tratamiento, con las repercusiones que este bienestar pueda generar también en el aspecto físico, más allá de la medicina tradicional.

ABSTRACT Introduction: Spirituality is a very broad concept for humanity, its consensus for the various groups is under permanent study. The importance of introducing its approach in the comprehensive health of the patient is increasingly significant in medical practice. Objectives: To validate the Steger MLQ scale of spiritual well-being in the Guarani language and evaluate the spiritual well-being in patients of the oncology and hemodialysis services of two referral centers. Methods: The target population was patients undergoing cancer treatment and dialysis from the oncology services of the Hospital de Clínicas (San Lorenzo) and the hemodialysis services of the Sanatorio Español-NefroServ (Asunción) during the months of May, June and July 2021. The Steger MLQ scale was used as the instrument. This questionnaire assesses two dimensions of meaning in life using ten items rated on a seven-point scale. The ethical aspects of human research were respected. Results: One hundred seven questionnaires were completed, 54 women and 53 men, 64 were taken in the hemodialysis service and 41 in the oncology service, 42 were done in Guarani and 65 in Spanish, according to the respondent's preference. The average age of the sample was 54.6 ± 14 years. Of those surveyed, 11.2% (12) had incomplete primary education, 25.2% (27) completed primary, 14.01% (15) incomplete secondary, 13.08% (14) secondary, 25.2% (27) tertiary and 11.2% (12) did not answer this question. In relation to religion, 99 stated that they profess the Catholic religion (92.5%). Cronbach's alpha reliability test was used to measure the degree of reliability of the scale carried out in the Guarani language, yielding a value of 0.87 (high reliability). Conclusion: It was possible to test the validity of the instrument in the Guarani language for the Guarani-speaking Paraguayan community. In addition, trends have been observed in terms of measuring spiritual well-being in the samples studied and their different profiles, which allows a more comprehensive approach to treatment, with the repercussions that this well-being can also generate in the physical aspect, beyond traditional medicine.

Evaluación de las necesidades de recursos humanos en salud: aplicación a la estimación de nefrólogos en Uruguay / Assessing the need for human resources in health: Nephrologist supply forecast in Uruguay / Avaliação das necessidades de recursos humanos em saúde: aplicação à estimativa de nefrologistas no Uruguai

Introducción: mejorar la salud de la población, considerando acceso universal con equidad, requiere de un número de profesionales y una distribución de los mismos adecuada a los problemas de salud de las personas. Las metodologías rigurosas deberían incorporar la identificación de las necesidades en salud para poder cumplir con este principio. Objetivo: estimar estándares de necesidad de nefrólogos para la población de Uruguay en 2020. Método: se conformó un grupo de referentes en nefrología procedentes de la academia y/o Sociedad Científica, se recabaron antecedentes y fuentes de la especialidad vinculadas a los problemas de salud renal en la población. Se definieron un conjunto de supuestos y condiciones iniciales. Se estimó la necesidad de nefrólogos de Uruguay para el año 2020, total del país y por departamento, expresada en valores absolutos y en términos de tasas de profesionales respecto a la población. Se identificaron escenarios alternativos de necesidad a partir de modificaciones de las condiciones iniciales. Resultados: para todo el país la necesidad de nefrólogos se estima entre 139 y 192 profesionales, esto implica una tasa de necesidad en un rango de 39 a 54 por millón de habitantes. Conclusiones: el estudio es el primero en Uruguay en reportar estándares de necesidad de nefrólogos expresados en términos de tasas de especialistas por población en diferentes escenarios definidos a partir de criterios que han sido explicitados y fundamentados.

Introduction: improving the health of populations by means of favoring universal access with equity requires the appropriate number and right distribution of professionals, according to the different health problems people face. Rigorous methodologies should include identification of health requirements in order to comply with this principle. Objective: to estimate the demand for nephrologists in the Uruguayan population in 2020. Method: a group of reference nephrologists - scholars or members of the scientific society - was formed to forecast the demand for these specialists. To that end they reviewed historical data and sources of this field of knowledge that have some connection with kidney diseases in the studied population. Subsequently, a number of assumptions and initial conditions were defined to conduct the study. The demand for nephrologists in Uruguay by 2020 was estimated for the whole country and by department, and it was expressed in absolute values and professional-to-population ratio. Alternative requirement scenarios were identified based on modifications to the initial conditions. Results: the demand for nephrologists is between 139 and 192 professionals, which implies a 39 to 54 per 1 million inhabitants ratio. Conclusions: this is the first one of this kind of studies conducted in Uruguay to report standards for nephrologists requirement in specialists per one million inhabitants, for different scenarios defined based on criteria that have been made explicit and backed.

Quality of Life and Associated Risk Factors in Hemodialysis: Perspective from a Center in the Dominican Republic

Background: Chronic kidney disease has an overall prevalence of 10 %. It can progress to a condition called end-stage renal disease. Therapies such as hemodialysis are necessary at this stage. Our study aims to measure the quality of life of patients on hemodialysis. Methods: We conducted an observational, cross-sectional study with 81 patients. Data was collected using a survey that included sociodemographic variables, the Center for Epidemiological Studies Depression Screening Index (CES-D), and the Kidney Disease Quality of Life (KDQOL-SF36). Data were analyzed using the software Epi Info™ 7.2, t-test, ANOVA, and correlation coefficient. Results: The severity of symptoms is more significant in the female sex than in males (65.7117 vs. 74.2874). All of the components of the KDQOL-SF36 showed a negative correlation with the CES-D. Household income had a mild positive correlation with the scale (r = 0.2608, p = 0.0229). Physical activity was shown to be associated with the physical component of the scale (41.6346 vs. 35.7365, p = 0.0412). Patients with partners were associated with higher quality of life scores than single patients (53.6585 vs. 42.6783, p = 0.0348). Conclusion: This is the first study conducted in the Dominican Republic to analyze the variables affecting the quality of life in patients in hemodialysis units. The severity of the symptoms increased in female patients, and patients without a partner are associated with worse quality of life scores.

Introducción: la enfermedad renal crónica presenta una prevalencia global del 10 % y puede progresar a una condición llamada enfermedad renal en etapa terminal. Terapias como la hemodiálisis son necesarias en esta etapa. Nuestro estudio tiene como objetivo medir la calidad de vida de pacientes en hemodiálisis. Método: se realizó un estudio observacional transversal, en el cual se recolectaron los datos de 81 pacientes. Para esto, se aplicó un cuestionario con las variables sociodemográficas, así como la escala CES-D y la escala KDQOL-SF36. Los datos se analizaron con el software Epi Info ™ 7.2. mediante la prueba t, ANOVA y el coeficiente de correlación. Resultados: la gravedad de los síntomas fue mayor en el sexo femenino que en el masculino (65,7117 vs. 74,2874). Los componentes de KDQOL-SF36 mostraron una correlación negativa con la puntuación de la escala CES-D. El ingreso del hogar tuvo una correlación positiva leve (r = 0,2608, p = 0,0229). La actividad física mostró estar asociada con la escala (41,6346 vs. 35,7365, p = 0,0412). Los pacientes con parejas tuvieron mejor calidad de vida que los pacientes solteros (53.6585 vs 42.6783, p = 0.0348). Conclusiones: este es el primer estudio realizado en la República Dominicana con el fin de evaluar las variables que afectan la calidad de vida de los pacientes en hemodiálisis. La gravedad de los síntomas aumentó en pacientes del sexo femenino y vivir sin pareja estuvo asociado a un menor puntaje en las escalas de calidad de vida.

Safety and efficacy of arteriovenous fistula angioplasties performed by nephrologists: report from a Brazilian interventional nephrology center / Segurança e eficácia de angioplastias de fístulas arteriovenosas realizadas por nefrologistas: relato de um centro de nefrologia intervencionista brasileiro

ABSTRACT Introduction: Arteriovenous fistulas (AVF) are the first choice vascular access for hemodialysis. However, they present a high incidence of venous stenosis leading to thrombosis. Although training in interventional nephrology may improve accessibility for treatment of venous stenosis, there is limited data on the safety and efficacy of this approach performed by trained nephrologists in low-income and developing countries. Methods: This study presents the retrospective results of AVF angioplasties performed by trained nephrologists in a Brazilian outpatient interventional nephrology center. The primary outcome was technical success rate (completion of the procedure with angioplasty of all stenoses) and secondary outcomes were complication rates and overall AVF patency. Findings: Two hundred fifty-six angioplasties were performed in 160 AVF. The technical success rate was 88.77% and the main cause of technical failure was venous occlusion (10%). The incidence of complications was 13.67%, with only one patient needing hospitalization and four accesses lost due to the presence of hematomas and/or thrombosis. Grade 1 hematomas were the most frequent complication (8.2%). The overall patency found was 88.2 and 80.9% at 180 and 360 days after the procedure, respectively. Conclusion: Our findings suggest that AVF angioplasty performed by trained nephrologists has acceptable success rates and patency, with a low incidence of major complications as well as a low need for hospitalization.

RESUMO Introdução: As fístulas arteriovenosas (FAV) são a primeira escolha de acesso vascular para hemodiálise. No entanto, elas apresentam uma alta incidência de estenoses venosas levando à trombose. Embora o treinamento em nefrologia intervencionista possa melhorar a acessibilidade para o tratamento das estenoses venosas, há dados limitados sobre a segurança e a eficácia desta abordagem realizada por nefrologistas treinados em países em desenvolvimento e de baixa renda. Métodos: Este estudo apresenta os resultados retrospectivos de angioplastias de FAV realizadas por nefrologistas treinados em um centro ambulatorial brasileiro de nefrologia intervencionista. O desfecho primário foi a taxa de sucesso técnico (conclusão do procedimento com angioplastia de todas as estenoses) e os desfechos secundários foram taxas de complicação e a patência geral das FAV. Achados: Duzentas e cinquenta e seis angioplastias foram realizadas em 160 FAV. A taxa de sucesso técnico foi de 88,77% e a principal causa de falha técnica foi a oclusão venosa (10%). A incidência de complicações foi de 13,67%, com apenas um paciente necessitando de internação e quatro acessos perdidos devido à presença de hematomas e/ou trombose. Hematomas de grau 1 foram a complicação mais frequente (8,2%). A patência geral encontrada foi de 88,2 e 80,9% a 180 e 360 dias após o procedimento, respectivamente. Conclusão: Nossos achados sugerem que a angioplastia de FAV realizada por nefrologistas treinados tem taxas de sucesso e patência aceitáveis, com uma baixa incidência de complicações maiores, bem como uma baixa necessidade de hospitalização.

The Brazilian Society of Nephrology Code of Conduct: a bioethical analysis / Código de Conduta da Sociedade Brasileira de Nefrologia: uma análise bioética

Abstract Introduction: Professional deontology can be defined as a set of principles, values and rules of conduct to be applied in the exercise of functions and inherent to a given profession. Nephrology was one of the medical specialties most affected by the mismatch between the accelerated technological development and the ethical dilemmas resulting from it. Recently, the Brazilian Society of Nephrology (SBN) edited its code of conduct, which until then did not exist. Method: Qualitative study with content analysis of the chapters and articles of the SBN Code of Conduct, from the perspective of principlism bioethics. Results: The four moral principles of beneficence, non-maleficence, autonomy and justice were found asymmetrically throughout the document, with beneficence predominating over the others. Discussion: The SBN Code of Conduct predominantly expresses the ethical duties that an associate must comply with, but also restrictions on malfeasance, autonomy and justice, anchoring decision-making by managers and including the distribution of possible punishments. It is an unfinished document; therefore, it must be periodically revised, as expected, due to the rapid technological changes, as well as the need for constructive moderation in the relations of nephrologists with each other and, between them, with the Industry, as well as all the ethical consequences arising from these factors.

Resumo Introdução: A deontologia profissional pode ser definida como determinado conjunto de princípios, valores e regras de conduta a serem aplicadas no exercício das funções e inerentes a uma determinada profissão. A nefrologia foi uma das especialidades médicas mais afetadas com o descompasso entre o acelerado desenvolvimento tecnológico e os dilemas éticos decorrentes dele. Recentemente, a Sociedade Brasileira de Nefrologia (SBN) editou seu código de conduta, até então inexistente. Método: Estudo qualitativo com análise de conteúdo dos capítulos e artigos do Código de Conduta da SBN, sob a ótica da bioética principialista. Resultados: Os quatro princípios morais de beneficência, não maleficência, autonomia e justiça foram encontrados de maneira assimétrica em todo o documento, com predomínio da beneficência sobre os demais. Discussão: O Código de Conduta da SBN exprime de maneira predominante os deveres éticos a que um associado deve se atentar, mas também restrições à maleficência, autonomia e justiça, ancorando a tomada de decisão pelos gestores e incluindo a distribuição de possíveis punições. É um documento inacabado, portanto deve ser revisto periodicamente, como previsto, em virtude das rápidas transformações tecnológicas, bem como da necessidade de moderação construtiva das relações dos nefrologistas entre si e, destes, com a Indústria, bem como todos os desdobramentos éticos advindos desses fatores.
