Caracterización de la situación problémica en un estudio psicosocial con pacientes con enfermedad renal crónica

Introducción: La enfermedad renal crónica es un problema de salud a nivel mundial, su manifestación más grave, la insuficiencia renal crónica, incide en el contexto cubano y determina el crecimiento de pacientes en hemodiálisis. El objetivo del texto es valorar los principales resultados del diagnóstico y caracterización de la situación problémica en un estudio de carácter psicosocial con pacientes con Insuficiencia Renal Crónica en la sala de Hemodiálisis del municipio Florida, de la provincia de Camagüey. Método: Es una investigación-acción participativa de corte experimental, que se desarrolla entre enero 2023 y diciembre del 2024 la cual constituye salida del proyecto de investigación Sistema de acciones psicosociales para el perfeccionamiento de la atención integral a los pacientes con enfermedades no transmisibles. El universo está constituido por 56 pacientes y la muestra por 22, que reciben tratamiento depurador y conservador, 22 familiares y 12 profesionales del servicio. El instrumento de investigación por excelencia fue la encuesta a participantes. Resultados: La edad de los pacientes no es definitiva de un grupo etario; predominan los hombres; se constata un elevado por ciento de pacientes con poca tolerancia a la adherencia al tratamiento e insuficiente desarrollo de las habilidades psicosociales y declaran la necesidad de poseer conocimientos para lograr estados de salud que conlleven a la sobrevida. Discusión: No existe coincidencia con lo constatado en la determinación de los grupos etarios de prevalencia para la enfermedad, pero los especialistas insisten en que la enfermedad no es privativa de un período de vida específico; reconocen la importancia del conocimiento de los factores de riesgo por el paciente para la prevención, promoción y educación en salud y resaltan la necesidad de la comunicación y la empatía entre el personal de salud y el paciente, para lograr resultados y estados emocionales favorables ante la enfermedad y el tratamiento.

Introduction: Chronic kidney disease is a global health problem. Its most serious manifestation, chronic kidney failure, affects the Cuban context and determines the growth of patients on hemodialysis. The objective of the text is to evaluate the main results of the diagnosis and characterization of the problematic situation in a psychosocial study with patients with Chronic Renal Failure in the Hemodialysis room of the Florida municipality, of the county of Camagüey. Method: It is an experimental participatory action research, which takes place between January 2023 and December 2024, which constitutes the output of the research project System of psychosocial actions for the improvement of comprehensive care for patients with non-communicable diseases. The universe is made up of 56 patients and the sample is made up of 22, who receive purifying and conservative treatment, 22 family members and 12 service professionals. The research instrument par excellence was the participant survey. Results: The age of the patients is not definitive of an age group; men predominate; A high percentage of patients are found to have low tolerance for adherence to treatment and insufficient development of psychosocial skills and declare the need to possess knowledge to achieve health states that lead to survival. Discussion: There is no coincidence with what was found in the determination of the prevalence age groups for the disease, but specialists insist that the disease is not exclusive to a specific period of life; recognize the importance of the patient's knowledge of risk factors for prevention, promotion and health education and highlight the need for communication and empathy between health personnel and the patient, to achieve favorable results and emotional states in the face of the disease and treatment.

Bacteriemia asociada a catéteres venosos centrales no tunelizados en niños en hemodiálisis crónica / Bacteremia associated with non-tunneled central venous catheters in children undergoing chronic hemodialysis

Introducción. La infección asociada a catéter venoso central (CVC) es la principal complicación que presentan los pacientes en hemodiálisis en los que se usa este tipo de acceso. Objetivo. Estimar la incidencia de bacteriemia asociada a CVC no tunelizado, analizar la frecuencia de agentes causales y explorar factores de riesgo asociados en niños en hemodiálisis. Población y métodos. Estudio retrospectivo realizado en niños en hemodiálisis por CVC no tunelizado entre el 1 junio de 2015 y el 30 de junio de 2019. Para evaluar factores de riesgo predictores de bacteriemia asociada a CVC, se realizó regresión logística. Los factores de riesgo independiente se expresaron con odds ratio con sus respectivos intervalos de confianza del 95 %. Se consideró estadísticamente significativo un valor de p <0,05. Resultados. En este estudio se incluyeron 121 CVC no tunelizados. La incidencia de bacteriemia fue de 3,15 por 1000 días de catéter. El microorganismo aislado con mayor frecuencia fue Staphylococcus epidermidis (16 casos, 51,5 %). La infección previa del catéter fue el único factor de riesgo independiente encontrado para el desarrollo de bacteriemia asociada a CVC no tunelizado (OR: 2,84; IC95%: 1,017,96; p = 0,04). Conclusiones. El uso prolongado de los CVC no tunelizados para hemodiálisis crónica se asoció con una incidencia baja de bacteriemia. Los gérmenes grampositivos predominaron como agentes causales. La presencia de infección previa del CVC aumentó en casi 3 veces el riesgo de bacteriemia asociada a CVC en nuestra población pediátrica en hemodiálisis.

Introduction. Central venous catheter (CVC)-related infection is the main complication observed in patients undergoing hemodialysis with this type of venous access. Objective. To estimate the incidence of non-tunneled CVC-related bacteremia, analyze the frequency ofcausative agents, and explore associated risk factors in children undergoing hemodialysis. Population and methods. Retrospective study in children receiving hemodialysis via a non-tunneled CVC between June 1 st, 2015 and June 30 th, 2019. A logistic regression was carried out to assess risk factors that were predictors of CVC-related bacteremia. Independent risk factors were described as odds ratios with their corresponding 95% confidence interval (CI). A value of p < 0.05 was considered statistically significant. Results. A total of 121 non-tunneled CVCs were included in this study. The incidence of bacteremia was 3.15 per 1000 catheter-days. The most commonly isolated microorganism was Staphylococcus epidermidis(16 cases, 51.5%). Prior catheter infection was the only independent risk factor for the development of bacteremia associated with non-tunneled CVC (OR: 2.84, 95% CI: 1.01­7.96, p = 0.04). Conclusions. Prolonged use of non-tunneled CVCs for chronic hemodialysis was associated with a low incidence of bacteremia. Gram-positive microorganisms prevailed among causative agents. A prior CVC infection almost trebled the risk for CVC-related bacteremia in our pediatric population receiving hemodialysis.

Incremento del riesgo hemorrágico en pacientes con fibrilación auricular y enfermedad renal crónica en hemodiálisis tratados con anticoagulantes. Serie de cuatro centros / Increased risk of bleeding in patients with atrial fibrillation and chronic kidney disease on hemodialysis treated with anticoagulants. A four center series

Resumen Objetivo: El objetivo de este estudio fue estimar si el uso de anticoagulantes se asociaba con una diferencia en la frecuencia de trombosis de cualquier sitio, hemorragia mayor y mortalidad en adultos con coexistencia de ambas patologías. Método: Se realizó un estudio de cohorte retrospectivo en cuatro centros de alta complejidad. Se incluyeron mayores de 18 años con ERC en hemodiálisis y FA no valvular, con indicación de anticoagulación (CHA2DS2VASc ≥ 2). El desenlace primario fue la ocurrencia de sangrado mayor, evento trombótico (accidente vascular cerebral, infarto agudo al miocardio o enfermedad tromboembólica venosa) o muerte. Se realizó ajuste por variables de confusión por regresión logística. Resultados: De los 158 pacientes incluidos, el 61% (n = 97) recibieron anticoagulante. El desenlace principal se encontró en el 84% de quienes recibieron anticoagulación y en el 70% de quienes no la recibieron (OR: 2.12, IC95%: 0.98-4.57; luego del ajuste OR: 2.13, IC95%: 1.04-4.36). De los desenlaces mayores se presentaron sangrado en el 52% vs. el 34% (OR: 2.03; IC95%: 1.05-3.93), trombosis en el 35% vs. el 34% (OR: 1.03; IC95%: 0.52-2.01) y muerte en el 46% vs. el 41% (OR: 1.25; IC95%: 0.65-2.38). Conclusiones: Los resultados de este estudio sugieren un incremento en el riesgo de sangrado en los pacientes con FA y ERC en hemodiálisis que reciben anticoagulación, sin disminución del riesgo de eventos trombóticos ni de muerte.

Abstract Objective: The aim of this study was to estimate whether the consumption of anticoagulants was associated with a difference in the frequency of thrombosis of any site, major bleeding and mortality, in adults with both diseases. Method: A retrospective cohort study was carried out in four high complexity centers. Patients older than 18 years with CKD on hemodialysis and non-valvular AF, with an indication for anticoagulation (CHA2DS2VASc ≥ 2), were included. The primary outcome was the occurrence of: major bleeding, thrombotic event (cerebrovascular accident, acute myocardial infarction or venous thromboembolic disease) or death. Adjustment for confounding variables was performed using logistic regression. Results: From 158 patients included, 61% (n = 97) received an anticoagulant. The main outcome was found in 84% of those who received anticoagulation and 70% of those who did not (OR: 2.12, 95%CI: 0.98-4.57; after the adjusted analysis OR: 2.13, 95%CI: 1.04-4.36). Separate outcomes were bleeding in 52% vs. 34% (OR: 2.03; 95%CI: 1.05-3.93), thrombosis in 35% vs. 34% (OR: 1.03; 95%CI: 0.52-2-01) and death in 46% vs. 41% (OR: 1.25; 95%CI: 0.65-2.38). Conclusions: The results of this study suggest an increased risk of bleeding in patients with AF and CKD on hemodialysis receiving anticoagulation, without a decrease in the risk of thrombotic events or all-cause mortality.

Accesibilidad, disponibilidad y asequibilidad de medicamentos para Niños con Enfermedad Renal Crónica en Guatemala / Access, availability and affordability of medications for children with Advanced Chronic Kidney Disease in Guatemala

El artículo tiene como objetivo analizar la disponibilidad, acceso y asequibilidad de los medicamentos para niños con Enfermedad Renal Crónica (ERC) en tratamiento con hemodiálisis (HD) en un país de bajos a medianos ingresos. Se llevó a cabo un estudio transversal para determinar los medicamentos más utilizados en una unidad de hemodiálisis pediátrica, incluyendo el nombre del medicamento, dosis, frecuencia, forma farmacéutica y vía de administración. Dos farmacias dentro del perímetro del hospital, una pública y una privada, fueron consultadas para determinar el costoy disponibilidad de medicamentos genéricos y de marca. De un total de 30 pacientes de la unidad de hemodiálisis, 22 expedientes fueron revisados. En general 94% de marca se encontraban disponibles en las farmacias consultadas en comparación a un 52% de los medicamentos genéricos. En farmacias públicas, 41% de medicamentos de marca y 29% de medicamentos genéricos se encontraban disponibles. El costo promedio para un mes de tratamiento con medicamentos de marca adquiridos en una farmacia privada era de $495.00 vs $299.00 en una farmacia pública. Para medicamentos genéricos, el costo promedio correspondía a $414.00 y $239.00 en farmacias privadas y públicas respectivamente. En promedio, los medicamentos de marca adquiridos en una farmacia privada requieren 41 días de trabajo en un mes a comparación de 25 días si se adquieren en una farmacia pública. Los medicamentos genéricos adquiridos en farmacias privadas corresponden a 34 días de trabajo vs 20 días en farmacias públicas. En general existió un acceso limitado a medicamentos genéricos y los medicamentos poseen un costo general más elevado a comparación de otros países lo que implica un posible impacto en la adherencia terapéutica y los padecimientos secundarios de la ERC en los pacientes pediátricos en Guatemala. Esta realidad se puede aplicar a otros países de bajos a medianos ingresos.

This article aims to analyze the availability, access, and affordability of medications for children with advanced Chronic Kidney Disease (CKD) treated with hemodialysis (HD) in a low to middle income country (LMIC). A cross- sectional chart review was carried out to determine the most common medications used in an HD pediatric unit, including medication name, dose, frequency, dosage form, and route of administration. Two pharmacies within the hospital perimeter, one public and one private, were consulted to determine medication cost and availability for generic and brand-name equivalents. From 30 patients attending the HD unit, 22 records were reviewed. Overall, 94 % of brand name medications were available at pharmacies consulted, versus and 52% of generic medications. In public pharmacies, 41% of brand name, and 29% of generic medications were available. The average cost for a full month´s treatment for brand name drugs in the private pharmacy was 495.00 USD versus 299.00 USD in the public pharmacy. For generic drugs, the average cost was 414.00 USD, and 239.00 USD in private and public pharmacies respectively. On average, brand-name drugs in the private pharmacy cost 41 days' wages versus 25 in the public pharmacy. Generic drugs in the private pharmacy cost 34 days' wages versus 20 in the public pharmacy. Overall, there was limited access to generic medications, medications had an overall high cost compared to other countries both of which have the potential to impact treatment adherence and overall outcomes of CKD5 pediatric patients in Guatemala. This reality can be translated to other LMIC.

The association between C-reactive protein/albumin ratio and the risk of cardiovascular events in mainte-nance hemodialysis patients / 实用医学杂志

Objective To explore the association between C-reactive protein/albumin ratio(CAR)and the risk of cardiovascular events in maintenance hemodialysis(MHD)patients.Methods This study enrolled MHD patients who were treated in the blood purification center of the Second Affiliated Hospital of Guangzhou Medical University between August 2016 to December 2019,and the follow-up deadline was March 31,2021.Collected the clinical data of patients who conform to the inclusion criteria,including demographic,complications,primary basic disease,biochemical indicators of the patients who underwent 3 months regular dialysis treatment and the occurrence of cardiovascular events during the follow-up period.The Kaplan-Meier method was used to estimate the probability of cardiovascular incidents in MHD patients.The Cox proportional hazards model based on generalized propensity score weighting(GPSW)was used to estimate the relationship between CAR and cardiovas-cular events in MHD patients.Results A total of 170 eligible objects were included in this study,64 patients with cardiovascular events(37.6%).The Cox proportional hazards model which based on GPSW(HRCAR = 2.087,95%CI:1.085～4.015,P = 0.028),indicated that the hazard ratio of cardiovascular events was 2.087 when the CAR each additional a unit in MHD patients.Conclusion CAR and the risk of cardiovascular events in MHD patients have a significant positive correlation,which can help clinical workers recognize the MHD patients who have high risk of cardiovascular events and intervene in time.

Prognostic risk factors of catheter-related bloodstream infection in patients with maintenance hemodialysis / 中华危重病急救医学

Objective:To analyze the pathogen distribution and prognostic risk factors of catheter-related bloodstream infection (CRBSI) in patients with maintenance hemodialysis (MHD) during non-hospitalization.Methods:A retrospective comparative study was conducted. Thirty-four patients of MHD with semi-permanent catheter admitted to the department of nephrology of Gansu Provincial Hospital from January 2020 to May 2023 due to CRBSI during non-hospitalization were enrolled. The distribution characteristics of pathogens causing CRBSI in MHD patients during non-hospital period were analyzed. All patients were actively given anti-infection treatment after admission. The general data, laboratory indicators and prognosis during hospitalization were collected through the electronic medical record system. Patients were divided into poor prognosis group (14 cases) and good prognosis group (20 cases) according to the treatment results during hospitalization. Univariate and binary Logistic regression were used to analyze the risk factors affecting the prognosis of patients, and receiver operator characteristic curve (ROC curve) was drawn to evaluate its predictive value for prognosis.Results:A total of 28 pathogenic bacteria were isolated from 34 patients, of which 25 were Gram-positive, Staphylococcus was the most common pathogen, accounting for 82.15% of the total, and 16 strains of Staphylococcus aureus (57.15%), including 6 methicillin-resistant Staphylococcus aureus (MRSA, 21.43%). There were 7 strains of Staphylococcus epidermidis (25.00%), including 3 strains of methicillin-resistant Staphylococcus epidermidis (MRSE, 10.71%). There were 3 strains of Gram-negative bacteria, 1 strain each of Pseudomonas aeruginosa, Escherichia coli and Acinetobacter baumannii. Univariate analysis showed that the fever duration of MHD patients with CRBSI in the poor prognosis group was significantly longer than that in the good prognosis group [days: 8.50 (3.75, 45.00) vs. 2.50 (1.00, 4.75), P < 0.01], serum erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and random blood glucose (GLU) were significantly higher than those in the good prognosis group [ESR (mm/1 h): 82.36±24.98 vs. 56.95±35.65, CRP (mg/L): 123.45±74.10 vs. 67.35±55.22, GLU (mmol/L): 8.74±3.66 vs. 6.42±1.95, all P < 0.05]. Binary Logistic regression analysis showed that serum CRP was an independent risk factor for poor prognosis in MHD patients with CRBSI [odds ratio ( OR) = 1.020, 95% confidence interval (95% CI) was 1.002-1.038, P = 0.025]. ROC curve analysis showed that the area under the curve (AUC) of serum CRP in predicting poor prognosis of MHD patients with CRBSI was 0.711; when the optimal cut-off value was 104.65 mg/L, the sensitivity was 64.3% and the specificity was 85.0%, indicating that it has good predictive value. Conclusions:Gram-positive bacteria are the main pathogens of CRBSI in MHD patients during non-hospital period. The poor prognosis is mainly related to the high level of serum CRP. Serum CRP level can effectively screen the high-risk group of MHD patients with CRBSI with poor prognosis.

Effect of humanistic care nursing combined with Morita therapy on anxiety state of hemodialysis patients / 中华健康管理学杂志

Objective:To explore the effect of humanistic care combined with Morita therapy on anxiety state of hemodialysis patients.Methods:A self-controlled study was conducted on 54 patients with end-stage renal disease and anxiety who received maintenance hemodialysis in China-Japan Friendship Hospital from August 2020 to August 2022. All patients were treated with humanistic care nursing and Morita therapy for one month. The Self Rating Anxiety Scale (SAS) scores of the patients before and after the intervention were compaired. The comparison of quantitative data was conducted by paired t-test, and the comparison of qualitative data was conducted by χ2 test. The correlation between different factors and anxiety was analyzed by Spearman correlation analysis. Results:Among the 54 patients, there were 26 males and 28 females, aged (61.8±16.3) years (ranging from 29 to 88 years). The SAS score after the intervention (44.0±11.1) was lower than that before the intervention (51.9±8.5) ( t=5.395, P<0.001). The anxiety of patients was related to their age ( r=0.305), employment status ( r=0.270) and marital status ( r=0.397) (all P<0.05). The satisfaction of patients with care measures and nursing before and after the intervention was 45.6% and 87.7%, respectively ( χ2=5.720, P<0.05). Conclusion:After receiving combined humanistic care nursing and Morita therapy, patients in a state of anxiety could experience significant psychological improvement, which is conducive to the successful completion of hemodialysis treatment and enhances the quality of life for patients.
