RESUMEN
Introduction: Patients with end-stage renal disease (ESRD) frequently change renal replacement (RRT) therapy modality due to medical or social reasons. We aimed to evaluate the outcomes of patients under peritoneal dialysis (PD) according to the preceding RRT modality. Methods: We conducted a retrospective observational single-center study in prevalent PD patients from January 1, 2010, to December 31, 2017, who were followed for 60 months or until they dropped out of PD. Patients were divided into three groups according to the preceding RRT: prior hemodialysis (HD), failed kidney transplant (KT), and PD-first. Results: Among 152 patients, 115 were PD-first, 22 transitioned from HD, and 15 from a failing KT. There was a tendency for ultrafiltration failure to occur more in patients transitioning from HD (27.3% vs. 9.6% vs. 6.7%, p = 0.07). Residual renal function was better preserved in the group with no prior RRT (p < 0.001). A tendency towards a higher annual rate of peritonitis was observed in the prior KT group (0.70 peritonitis/year per patient vs. 0.10 vs. 0.21, p = 0.065). Thirteen patients (8.6%) had a major cardiovascular event, 5 of those had been transferred from a failing KT (p = 0.004). There were no differences between PD-first, prior KT, and prior HD in terms of death and technique survival (p = 0.195 and p = 0.917, respectively) and PD efficacy was adequate in all groups. Conclusions: PD is a suitable option for ESRD patients regardless of the previous RRT and should be offered to patients according to their clinical and social status and preferences.
Introdução: Pacientes com doença renal em estágio terminal (DRET) frequentemente mudam de modalidade de terapia renal substitutiva (TRS) por razões médicas ou sociais. Nosso objetivo foi avaliar desfechos de pacientes em diálise peritoneal (DP) segundo a modalidade anterior de TRS. Métodos: Realizamos estudo retrospectivo observacional unicêntrico, em pacientes prevalentes em DP, de 1º de janeiro de 2010 a 31 de dezembro de 2017, acompanhados por 60 meses ou até saírem de DP. Pacientes foram divididos em três grupos de acordo com a TRS anterior: hemodiálise prévia (HD), transplante renal malsucedido (TR) e DP como primeira opção (PD-first). Resultados: Entre 152 pacientes, 115 eram PD-first, 22 transitaram da HD e 15 de TR malsucedido. Houve tendência à maior ocorrência de falência de ultrafiltração em pacientes em transição da HD (27,3% vs. 9,6% vs. 6,7%; p = 0,07). A função renal residual foi melhor preservada no grupo sem TRS prévia (p < 0,001). Observou-se tendência à maior taxa anual de peritonite no grupo TR prévio (0,70 peritonite/ano por paciente vs. 0,10 vs. 0,21; p = 0,065). Treze pacientes (8,6%) tiveram um evento cardiovascular maior, cinco dos quais haviam sido transferidos de um TR malsucedido (p = 0,004). Não houve diferenças entre PD-first, TR prévio e HD prévia em termos de óbito e sobrevida da técnica (p = 0,195 e p = 0,917, respectivamente) e a eficácia da DP foi adequada em todos os grupos. Conclusões: A DP é uma opção adequada para pacientes com DRET, independentemente da TRS anterior, e deve ser oferecida aos pacientes de acordo com seu status clínico e social e suas preferências.
RESUMEN
Introducción. Los pacientes con patología abdominal quirúrgica que requieren manejo con abdomen abierto son susceptibles a la pérdida de proteínas desde la cavidad expuesta. El objetivo de este estudio fue caracterizar la pérdida proteica a través de dos tipos de cierre temporal abdominal. Métodos. Se realizó un estudio decohorte prospectivo, con pacientes críticos manejados durante el año 2021 con abdomen abierto mediante dos tipos de cierre temporal: bolsa de Bogotá y ABThera™. Se recolectaron muestras intraoperatorias seriadas de líquido peritoneal (días 1, 3 y 5). Se calcularon frecuencias y promedios, y se compararon con las pruebas de Chi cuadrado y t de Student. Resultados. Se incluyeron 25 pacientes. El promedio de pérdida de proteínas en líquido peritoneal fue mayor con el sistema ABThera™ (44,38 g/L) comparado con la bolsa de Bogotá (25,18 g/L; p=0,0185). Durante el seguimiento se observó la tendencia a la disminución del promedio de proteínas perdidas por ambos sistemas, pero con ABThera™ se perdieron en promedio 15,47 gr/L más de proteínas, independientemente del estado nutricional y del aporte proteico recibido (p=0,042). No hubo diferencias según la etiología que llevó al manejo con abdomen abierto, los procedimientos quirúrgicos realizados o el estado de infección por COVID-19. Conclusiones. El abdomen abierto representa una fuente importante de pérdida de proteínas, que es diferente según el tipo de cierre temporal usado. Estas pérdidas deberían considerarse en los cálculos de soporte nutricional en la unidad de cuidado intensivo.
Introduction. Patients with surgical abdominal pathology requiring management with an open abdomen are susceptible to protein loss from the exposed cavity. The objective of this study was to characterize protein loss through two types of temporary abdominal closure. Methods. A prospective cohort study was carried out with critically ill patients managed during 2021 with an open abdomen using two types of temporary closure: Bogota bag and ABThera™. Serial intraoperative peritoneal fluid samples were collected (days 1, 3, and 5). Frequencies and averages were calculated and compared with the Chi square and Student's t tests. Results. Twenty-five patients were included. The average protein loss in peritoneal fluid was higher with the ABThera™ system (44.38 g/L) compared to the Bogota bag (25.18 g/L; p-value=0.0185). During follow-up, a tendency to decrease the average protein lost by both systems was observed, but with ABThera™ an average of 15.47 gr/L more protein was lost, regardless of the nutritional status and protein intake received (p=0.042). There were no differences based on etiology leading to open abdomen management, surgical procedures performed, or Covid-19 infection status. Conclusions. The open abdomen represents an important source of protein loss, which is different depending on the type of temporary closure used. These losses should be considered in calculations of nutritional support in the intensive care unit.

Background: The coronary artery calcium score and left atrial volume have been shown to predict the incidence of acute myocardial infarction and death from cardiovascular disease in patients undergoing peritoneal dialysis. However, the association between these factors has not been well-established. Methods: This cross-sectional, prospective, single-center study was conducted on patients undergoing outpatient peritoneal dialysis, who were followed up at a university hospital between March 2018 and August 2019. The coronary artery calcium score was calculated based on cardiovascular computed tomography findings. The score was "positive" when it was ≥100 Agatston and "negative" when it was <100 Agatston. The left atrial volume was obtained using the biplane disc method at the end of the left ventricular systole, and then it was indexed to the body surface. Results: Forty-four patients were evaluated. They had an age [mean (range)] of 56 (43-65) years and had been on dialysis therapy for 11.7 (6.8-25.4) months. Univariate analysis revealed a relationship between the coronary artery calcium score and left atrial volume index and the following variables: age, diabetes, overhydration, pulse wave velocity, E/A ratio, and left ventricular mass index. In multivariate logistic regression analysis, only the left atrial volume index was independently associated with a positive coronary artery calcium score. Conclusions: The left atrial volume index was associated with a positive coronary artery calcium score in patients on peritoneal dialysis, regardless of other factors. It may be a useful risk marker for coronary artery disease in this population.
RESUMEN
Background: Robot-assisted radical prostatectomy with intraoperative pelvic lymph node dissection is the criterion standard for surgical treatment of nonmetastatic intermediate- and high-risk prostate cancer. However, this method is associated with symptomatic lymphocele (SLC), which is an important morbidity factor. To overcome this complication, several modifications of the technique have been developed, including the peritoneal interposition flap (PIF). We performed an updated systematic review and meta-analysis to investigate the efficacy and safety of this technique for preventing SLC and lymphocele (LC) formation. Materials and methods: Searches were performed using databases and references from included studies and previous systematic reviews. Only randomized controlled trials and nonrandomized cohorts were included. Primary outcomes were the incidence of SLC and LC formation, and safety outcomes were defined as operation time, estimated blood loss, length of hospital stay, and urinary incontinence. Quality assessment was performed using the Newcastle-Ottawa Scale and Cochrane Collaboration's tool. Pooled treatment effects were estimated using odds ratios with 95% confidence intervals (CIs) for binary endpoints. Heterogeneity was examined using Cochran's Q test and I 2 statistics; p values < 0.10 and I 2 > 25% were considered significant for heterogeneity. We used Mantel-Haenszel fixed-effect models in the analyses with low heterogeneity. Otherwise, the DerSimonian and Laird random-effects model was used. Results: The initial search yielded 510 results. After the removal of duplicate records and application of the exclusion criterion, 9 studies were fully reviewed for eligibility. Three randomized controlled trials and 5 retrospective cohorts met all the inclusion criteria, comprising 2261 patients, of whom 1073 (47.4%) underwent PIF. Six studies reported a significant reduction in SLC in the PIF group, and 3 of the 4 studies reported LC formation yielded significant results in preventing this complication. The incidence of SLC and LC formation in a follow-up of ≥3 months was significantly different between the PIF and no PIF group (odds ratio, 0.34 [95% CI, 0.160.74; p = 0.006] and 0.48 [95% CI, 0.310.74; p = 0.0008]), respectively. The safety outcomes did not differ significantly between the 2 groups. Conclusions: These results suggest that PIF is an effective and safe technique for preventing LC and SLC in patients undergoing transperitoneal robot-assisted radical prostatectomy and pelvic lymph node dissection.
RESUMEN
Gut microbiota disturbances may influence cognitive function, increasing uremic toxins and inflammation in dialysis patients; therefore, we aimed to evaluate the association of the gut microbiota profile with cognitive impairment (CI) in patients on automated peritoneal dialysis (APD). In a cross-sectional study, cognitive function was evaluated using the Montreal Cognitive Assessment in 39 APD patients and classified as normal cognitive function and CI. The gut microbiota was analyzed using the 16S rRNA gene sequencing approach. All patients had clinical, biochemical and urea clearance evaluations. Eighty-two percent of patients were men, with a mean age of 47 ± 24 years and 11 (7-48) months on PD therapy; 64% had mild CI. Patients with CI were older (53 ± 16 vs. 38 ± 14, p = 0.006) and had a higher frequency of diabetes mellitus (56% vs. 21%, p = 0.04) and constipation (7% vs. 48%, p = 0.04) and lower creatinine concentrations (11.3 ± 3.7 vs. 14.9 ± 5.4, p = 0.02) compared to normal cognitive function patients. Patients with CI showed a preponderance of S24_7, Rikenellaceae, Odoribacteraceae, Odoribacter and Anaerotruncus, while patients without CI had a greater abundance of Dorea, Ruminococcus, Sutterella and Fusobacteria (LDA score (Log10) > 2.5; p < 0.05). After glucose and age adjustment, Odoribacter was still associated with CI. In conclusion, patients with CI had a different gut microbiota characterized by the higher abundance of indole-producing and mucin-fermenting bacteria compared to normal cognitive function patients.

Background: Knowledge of one's own chronic kidney disease (CKD) can improve long-term quality of life (QoL). Peritoneal dialysis presents with residual symptoms that reduce the QoL. Objective: To correlate knowledge of the disease and QoL in patients with CKD and on continuous ambulatory peritoneal dialysis (CAPD). Material and methods: A descriptive, cross-sectional, and prospective study was carried out in patients with CKD treated at a second-level hospital of the Mexican Institute for Social Security (Instituto Mexicano del Seguro Social) in Puebla. SF-36 and KiKS questionnaires were applied. Age, sex, education, marital status, perception of QoL, and level of knowledge were recorded. Descriptive statistics and Spearman's coefficient were used. Results: 199 patients with CKD in CAPD were included, 62.8% women, minimum age range was 18 to 20 years with 4% and maximum of 61 years or more with 49.2%, 35.6% of patients completed primary school, and 65.3% were married. The most frequent comorbidity was diabetes (57.2%). The least affected QoL domain was pain. KiKS recorded a mean of 0.54 (regular knowledge about the disease). It was recorded a weak and significant correlation in the QoL domains: physical health, physical role, pain, general health, mental health (p ≤ 0.05). Conclusions: There is a significant but weak correlation between the perception of QoL and the level of knowledge of the disease in CKD patients with CAPD.
Introducción: el conocimiento adecuado de la enfermedad renal crónica (ERC) puede mejorar la calidad de vida (CV) a largo plazo.

Pregnant women with end-stage kidney disease who undergo peritoneal dialysis have lower pregnancy rates and higher obstetric risk than their peers undergoing hemodialysis. Although there has been some improvement in pregnancy rates and outcomes due to the intensification of dialysis prescriptions, there is currently a lack of guidelines for optimizing peritoneal dialysis regimens for pregnant women with end-stage kidney disease. Besides, there is limited data available regarding pregnancy outcomes in women with end-stage kidney disease undergoing peritoneal dialysis. We report the case of a 23-year-old Hispanic woman with end-stage kidney disease caused by focal and segmental glomerulosclerosis. She became pregnant while undergoing successful treatment with an intensified automated peritoneal dialysis regimen. The patient gave birth to a live female preterm infant weighing 938 g during the 28th week of her pregnancy. The baby required neonatal intensive care due to prematurity, extremely low birth weight, and respiratory distress syndrome.
RESUMEN
La esclerosis peritoneal encapsulante es una entidad clínica, descrita hace 150 años, como un proceso inicialmente muy poco frecuente y relacionado a causas poco conocidas, designándose como Síndrome de capullo abdominal. A través del tiempo se han sumado otras causas, al aumentar los reportes clínicos, siendo la diálisis peritoneal de larga duración uno de los factores de riesgo que en la actualidad ha permitido esclarecer los procesos fisiopatológicos, que conllevan los cambios por los que atraviesa una cavidad abdominal que responde a un proceso externo como una agresión, efectuando una reacción persistente de inflamación, fibrosis y esclerosis cuya base es el reemplazo mesotelial mesenquimatoso, y donde se suman otros procesos como las infecciones que aumentan la cascada de mediadores inflamatorios, efectuándose la disposición estructural de la cavidad abdominal y su contenido de manera peculiar en esta patología.

Encapsulating peritoneal sclerosis is a clinical entity, described 150 years ago, as a process initially very infrequent and related to little known causes, being designated as Abdominal cocoon syndrome. Over time, other causes have been added, as clinical reports have increased, being long-term peritoneal dialysis one of the risk factors that currently has allowed to clarify the pathophysiological processes, which entail the changes through which an abdominal cavity that responds to an external process such as an aggression goes through, This process produces a persistent reaction of inflammation, fibrosis and sclerosis based on mesenchymal mesothelial mesenchymal replacement, and where other processes are added such as infections that increase the cascade of inflammatory mediators, making the structural arrangement of the abdominal cavity and its contents in a peculiar way in this pathology.

RESUMEN
Abstract Introduction: The Brazilian Dialysis Survey (BDS) is an annual national survey about patients on chronic dialysis that contributes to health policies. Objective: To report the 2022 epidemiological data from the BDS of the Brazilian Society of Nephrology (BSN). Methods: A survey was carried out in Brazilian chronic dialysis centers using an online questionnaire that included clinical and epidemiological aspects of patients on chronic dialysis, dialysis therapy data, and dialysis center characteristics. Results: Overall, 28% (n = 243) of the centers answered the questionnaire. In July 2022, the estimated total number of patients on dialysis was 153,831. The estimated prevalence and incidence rates of patients per million population (pmp) were 758 and 214, respectively. Of the prevalent patients, 95.3% were on hemodialysis (HD, 4.6% of these on hemodiafiltration) and 4.7% on peritoneal dialysis (PD). Only 1.3% of patients were not vaccinated against COVID-19. The prevalence of anemia (Hb < 10g/dL) was 27% and hyperphosphatemia (P > 5.5mg/dL) reached 30%. The estimated overall crude annual mortality rate was 17.1%. Conclusions: The absolute number and prevalence rate of patients on chronic dialysis continue to increase. A growing number of patients were receiving hemodiafiltration. The mortality rate decreased, probably due to the end of COVID-19 pandemic. The conclusions were drawn in the context of relatively low voluntary participation, which imposed methodological limitations on our estimates.
Resumo Introdução: O Censo Brasileiro de Diálise (CBD) é uma pesquisa nacional anual sobre pacientes em diálise crônica que contribui para as políticas de saúde. Objetivo: Informar os dados epidemiológicos de 2022 do CBD da Sociedade Brasileira de Nefrologia (SBN). Métodos: Foi realizada uma pesquisa em centros brasileiros de diálise por meio de um questionário online que incluiu aspectos clínicos e epidemiológicos de pacientes em diálise crônica, dados da terapia dialítica e características do centro de diálise. Resultados: No total, 28% (n = 243) dos centros de diálise ativos cadastrados na SBN responderam ao questionário. Em julho de 2022, o número total estimado de pacientes em diálise era de 153.831. As taxas estimadas de prevalência e incidência de pacientes por milhão (ppm) de habitantes foram 758 e 214, respectivamente. Dos pacientes prevalentes, 95,3% estavam em hemodiálise (HD; 4,6% desses em hemodiafiltração) e 4,7% em diálise peritoneal (DP). Apenas 1,3% dos pacientes não foram vacinados contra a COVID-19. A prevalência de anemia (Hb < 10g/dL) foi de 27% e de hiperfosfatemia (P > 5,5mg/dL) alcançou 30%. A taxa bruta total anual de mortalidade estimada foi de 17,1%. Conclusões: O número absoluto e a taxa de prevalência de pacientes em diálise crônica continuam a aumentar. Um número crescente de pacientes estava em hemodiafiltração. A taxa de mortalidade diminuiu, provavelmente devido ao fim da pandemia da COVID-19. As conclusões foram de um contexto de participação voluntária relativamente baixa, o que impõe limitações metodológicas às nossas estimativas.
RESUMEN
INTRODUCTION: In some studies, the peritoneal solute transfer rate (PSTR) through the peritoneal membrane has been related to an increased risk of mortality. It has been observed in the literature that those patients with rapid diffusion of solutes through the peritoneal membrane (high/fast transfer) and probably those with high average transfer characterized by the Peritoneal Equilibrium Test (PET) are associated with higher mortality compared to those patients who have a slow transfer rate. However, some authors have not documented this fact. In the present study, we want to evaluate the (etiological) relationship between the characteristics of peritoneal membrane transfer and mortality and survival of the technique in an incident population on peritoneal dialysis in RTS Colombia during the years 2007-2017 using a competing risk model. MATERIALS AND METHODS: A retrospective cohort study was carried out at RTS Colombia in the period between 2007 and 2017. In total, there were 8170 incident patients older than 18 years, who had a Peritoneal Equilibration Test (PET) between 28 and 180 days from the start of therapy. Demographic, clinical, and laboratory variables were evaluated. The (etiological) relationship between the type of peritoneal solute transfer rate at the start of therapy and overall mortality and technique survival were analyzed using a competing risk model (cause-specific proportional hazard model described by Royston-Lambert). RESULTS: Patients were classified into four categories based on the PET result: Slow/Low transfer (16.0%), low average (35.4%), high average (32.9%), and High/Fast transfer (15.7%). During follow-up, with a median of 730 days, 3025 (37.02%) patients died, 1079 (13.2%) were transferred to hemodialysis and 661 (8.1%) were transplanted. In the analysis of competing risks, adjusted for age, sex, presence of DM, HTA, body mass index, residual function, albumin, hemoglobin, phosphorus, and modality of PD at the start of therapy, we found cause-specific HR (HRce) for high/fast transfer was 1.13 (95% CI 0.98-1.30) pâ¯=â¯0.078, high average 1.08 (95% CI 0.96-1.22) pâ¯=â¯0.195, low average 1.09 (95% CI 0.96-1.22) pâ¯=â¯0.156 compared to the low/slow transfer rate. For technique survival, cause-specific HR for high/rapid transfer of 1.22 (95% CI 0.98-1.52) pâ¯=â¯0.66, high average HR was 1.10 (95% CI 0.91-1.33) pâ¯=â¯0.296, low average HR of 1.03 (95% CI 0.85-1.24) pâ¯=â¯0.733 compared with the low/slow transfer rate, adjusted for age, sex, DM, HTA, BMI, residual renal function, albumin, phosphorus, hemoglobin, and PD modality at start of therapy. Non-significant differences. CONCLUSIONS: When evaluating the etiological relationship between the type of peritoneal solute transfer rate and overall mortality and survival of the technique using a competing risk model, we found no etiological relationship between the characteristics of peritoneal membrane transfer according to the classification given by Twardowski assessed at the start of peritoneal dialysis therapy and overall mortality or technique survival in adjusted models. The analysis will then be made from the prognostic model with the purpose of predicting the risk of mortality and survival of the technique using the risk subdistribution model (Fine & Gray).

Gastric cancer (GC) with peritoneal carcinomatosis (PC) has a particularly unfavorable prognosis. This limited survival raises doubts about which factors confer an extremely worse outcome and which patients could benefit from more aggressive treatments, in an attempt to improve survival and better control the disease. This study aimed to evaluate the survival outcomes of patients with PC due to GC and develop a prognostic score to predict 6-month mortality. We performed an analysis of clinical stage IV GC with PC. Scores were assigned to risk factors and calculated for each patient from nine variables. Among 326 IVB GC, 211 (64.7%) had PC and were included. After calculating the score, 136 (64.5%) GCs were classified as a low-risk group and 75 (35.5%) as a high-risk group. Median OS was 7.9 and 1.9 months for low- and high-risk patients (p < 0.001). In the high-risk group, 77.3% of the patients died in <6 mo (p < 0.001). Palliative surgery and chemotherapy were associated with better survival, and the prognostic groups maintained statistical significance even when the same type of treatment was performed. In conclusion, the scoring system developed with variables related to patient performance status and clinical data was able to distinguish GC with PC with a high risk of 6-month mortality. Accordingly, verifying and validating our findings in a large cohort of patients is necessary to confirm and guarantee the external validation of the results.

A review from the last seven years (August 2016-July 2023) of questions posted to the International Society for Peritoneal Dialysis (ISPD) website "Questions about PD" by nurses and physicians from around the world revealed that 19 of the questions were associated with optimal approaches for preventing, assessing, and managing issues related to PD catheter non-infectious complications. Our review focused on responses to these questions whereby existing best practice recommendations were considered, if available, relevant literature was cited and differences in international practices discussed. We combined similar questions, revised both the original questions and responses for clarity, as well as updated the references to these questions. PD catheter non-infectious complications can often be prevented or, with early detection, the potential severity of the complication can be minimized. We suggest that the PD nurse is key to educating the patient on PD about PD catheter non-infectious complications, promptly recognize a specific complication and bring that complication to the attention of the Home Dialysis Team. The questions posted to the ISPD website highlight the need for more education and resources for PD nurses worldwide on the important topic of non-infectious complications related to PD catheters, thereby enabling us to prevent such complications as PD catheter malfunction, peri-catheter leakage and infusion or drain pain, as well as recognize and resolve these issues promptly when they do arise, thus allowing patients to extend their time on PD therapy and enhance their quality of life whilst on PD.

INTRODUCTION: Chronic kidney disease is a worldwide public health problem, with a high prevalence of patients on dialysis. mHealth technologies can greatly support the treatment and monitoring of these patients. Thus, this study aimed to evaluate the spontaneous use of the application (app) Renal Health, a previously available technology, for patients on hemodialysis and validate content to support patients undergoing peritoneal dialysis. METHODS: The first stage consisted of evaluating the spontaneous use of the app, and the second stage consisted of methodological research for the development, evaluation, and improvement of a technological instrument for use in clinical practice as a support for patients undergoing peritoneal dialysis (PD). The association between categorical variables was performed using the chi-square test, adopting a significance level of 5%. RESULTS: The app was accessed by 753 users and of these, 34 % accessed the hemodialysis section. Most accesses were in the state of São Paulo/Brazil and performed by women. The records of biochemical tests did not vary according to gender and age group (p > 0.05). The developed and validated PD section enables section control, allowing the user to manage their sessions. The analysis of the technology by the specialists showed good results for the global content validity index (CVI) regarding objectives (CVI = 0.95), structure (CVI = 0.97), and relevance (CVI = 1.0). CONCLUSION: It is concluded that the hemodialysis section of the Renal Health app aroused the interest of the population and that the developed peritoneal dialysis section was validated by specialists.

OBJECTIVES: This study aimed to determine the hospital service utilization patterns and direct healthcare hospital costs before and during peritoneal dialysis (PD) at home. METHODS: A retrospective cohort study of patients with kidney failure (KF) was conducted at a Mexican Social Security Institute hospital for the year 2014. Cost categories included inpatient emergency room stays, inpatient services at internal medicine or surgery, and hospital PD. The study groups were (1) patients with KF before initiating home PD, (2) patients with less than 1 year of home PD (incident), and (3) patients with more than 1 year of home PD (prevalent). Costs were actualized to international dollars (Int$) 2023. RESULTS: We found that 53% of patients with KF used home PD services, 42% had not received any type of PD, and 5% had hospital dialysis while waiting for home PD. The estimated costs adjusting for age and sex were Int$5339 (95% CI 4680-9746) for patients without home PD, Int$17 556 (95% CI 15 314-19 789) for incident patients, and Int$7872 (95% CI 5994-9749) for prevalent patients; with significantly different averages for the 3 groups (P < .001). CONCLUSIONS: Although the use of services and cost is highest at the time of initiating PD, over time, using home PD leads to a significant reduction in use of hospital services, which translates into institutional cost savings. Our findings, especially considering the high rates of KF in Mexico, suggest a pressing need for interventions that can reduce healthcare costs at the beginning of renal replacement therapy.

Abstract The aim of this study was to explore the association between differential percentages of dendritic cell (DC) subsets in peripheral blood and malignancy (grade and lymph node metastasis) of peritoneal adenocarcinoma patients and the frequencies of dendritic cell subsets in the normal controls. The peripheral blood of 30 patients with peritoneal adenocarcinoma and 12 healthy controls were collected for multicolor flow cytometry analysis. Peritoneal adenocarcinoma patients were grouped according to the malignant degree (grade and lymph node metastasis). Percentages of myeloid DCs (mDCs) and its subsets MDC1 and MDC2 in DCs were lower in peripheral blood of patients with peritoneal adenocarcinoma than in normal controls. The percentages of plasmacytoid dendritic cells (pDCs) and CD16+mDCs in DCs were higher than in normal controls. Compared with poor differentiation grade, patients with well/moderate differentiation grade had an increased percentage of CD16+mDCs. Contrary to CD16+mDCs, the percentage of MDC1 was lower in the well/moderate differentiation grade group. In patients with no lymph node metastasis, pDCs and CD16+mDCs levels were higher compared with patients with lymph node metastasis. mDCs and MDC1 levels had opposite results. pDCs were positively correlated with CD16+mDCs in peripheral blood of peritoneal patients, as was mDCs and MDC1. CD16+mDCs were negatively correlated with MDC1. The percentages of pDCs and CD16+mDCs in DCs were positively correlated with CD3+CD8+T cells, and pDCs also positively correlated with CD8+PD-1+T cells. Our results revealed that DCs subsets correlated with peritoneal adenocarcinoma malignancy. Dendritic cells play an independent role in the immune function of peritoneal adenocarcinoma.
RESUMEN
OBJECTIVE: Sex-specific differences in the epidemiology of chronic kidney disease, such as higher prevalence of women on pre-dialysis and men on chronic dialysis treatment, have been reported worldwide. In this regard, data from non-high-income countries are scarce. We aimed to compare the demographic, clinical, and dialysis characteristics of incident dialysis patients, both men and women, in a large cohort of Brazilian patients over a 12-year period. METHODS: This was a multicentric retrospective cohort study coordinated by the Brazilian Society of Nephrology. The study included all adult incident dialysis patients in the Brazilian Dialysis Registry from January 2011 to December 2022. The variables studied encompassed age, skin color, education, CKD etiology, predialysis nephrologist care, dialysis characteristics, and geographic region. Additionally, the sample was analyzed for each of the three 4-year periods over the 12 years of data collection. RESULTS: A total of 24,632 incident dialysis patients were included. Men were 59.1% of the dialysis population, remaining stable over the three 4-year periods. Besides other differences, women started dialysis younger (58.5 ± 16.2 years vs 59.5 ± 14.4 years; p < 0.001), had a lower educational level (less than 8 years at school: 54% vs 44%; p < 0.001), received more predialysis nephrologist care (46.2% vs 44.2%; p = 0.04), and had a higher prevalence of peritoneal dialysis (4.4% vs 3.5%; p = 0.03). CONCLUSION: We consistently observed a higher prevalence of men on dialysis and differences in demographic, clinical, and dialysis characteristics. The underlying reasons for these sex differences still necessitate further clarification.

The most common kidney replacement therapy (KRT) worldwide is hemodialysis (HD), and only 5%-10% of patients are prescribed peritoneal dialysis (PD) as KRT. Despite PD being a different method, these patients also present particular complications, such as oxidative stress, gut dysbiosis, premature aging, and mitochondrial dysfunction, leading to an inflammation process and high cardiovascular mortality risk. Although recent studies have reported nutritional strategies in patients undergoing HD with attempts to mitigate these complications, more information must be needed for PD patients. Therefore, this review provides a comprehensive analysis of recent studies of nutritional intervention to mitigate inflammation in PD patients.
