Background. Chronic renal disease (CRD) is a disease with a strong impact on the childhood Mexican population with short-range limiting and serious consequences. Poverty and a social environment devoid of social justice hinder timely medical attention and long-range rehabilitation. The aim of this study was to determine the differences regarding sociodemographic features in patients under treatment at Hospital Infantil de México Federico Gómez, with a 6-year difference: patients diagnosed in 2003 as compared to those diagnosed in 2009. Methods. A retrospective comparative study was carried out with end-stage chronic renal disease (ESRD) patients with information obtained from the clinical files. Data were obtained on age, gender, renal insufficiency etiology, socioeconomic level, type of financing, place of origin, and whether patient entered a rehabilitation program (dialysis or transplant).

Nephrology in Mexico started in 1955 with the opening of the nephrology department at Mexico’s National Heart Institute, where the first nephrology training program began in 1958. Pediatric nephrology care was first offered at Mexico’s Federico Gomez Children’s Hospital in 1953, among the first pediatric nephrology programs in the world. Kidney transplantation began in 1963 at the IMSS General Hospital. The Sociedad Mexicana de Nefrologia, the first Mexican nephrology society, was established in 1967, followed by the publication of Nefrologia Mexicana, its official journal, in 1980. Chronic kidney disease has emerged as a public health problem in Mexico. However, the fragmentation of the health system has resulted in unequal access to renal replacement therapy. Seguro Popular, a public health-care insurance for the poor, does not cover renal replacement therapy. As a consequence, many uninsured patients refuse dialysis, eventually abandon their treatment, or lose their kidney grafts because sustaining dialysis or immunosuppression becomes unaffordable. The lack of a national dialysis registry results in a vacuum of information on the burden of treated end-stage renal disease and its outcomes. In addition to the high burden of traditional risk factors (i.e., diabetes mellitus), a number of “hotspots” of chronic kidney disease of unknown origin have been recently described in the country. Despite the increased burden of chronic kidney disease, strategies to prevent chronic kidney disease have not been part of the nation’s noncommunicable disease health policies. Chronic kidney disease screening is not part of the National Health Surveys. Peritoneal dialysis continues to be the dialysis modality of choice, although a significant shift to hemodialysis has been observed over the last two decades. The number of nephrologists (9.1 per million population) is insufficient to match the demand imposed by the burden of chronic kidney disease. In conclusion, after 65 years of the beginning of nephrology in Mexico, kidney disease care remains unjust, unequal, and below the quality of international standards. The current infrastructure and resources are insufficient to satisfy the demand of renal care in our society. Therefore, it is important to consider it as a public health priority and to implement a comprehensive program for the prevention and control of this illness. The establishment of a national public policy for the prevention and treatment of chronic kidney disease is urgently needed. © Springer Nature

Background: Oral nutritional supplementation (ONS) with or without exercise (EX) could improve muscle mass (MM) in chronic kidney disease. Methods: Patients were randomized into two groups: (1) ONS and (2) ONS + EX. Thigh muscle area (cm2) and intramuscular lipid content via attenuation were evaluated at baseline and 6 months with computed tomography (CT) to measure MM quantity and quality. Physical function was measured by six-minute walk test (6 MWT), gait speed, handgrip strength (HGS), and Time Up and Go test (TUG) at baseline and 3 and 6 months.

Objetivos: Conocer los criterios médicos y su prioridad en la asignación de riñones de paciente fallecido en Pediatría, entre los integrantes de los Comités Internos de Trasplantes de seis hospitales. Valorar si con el método Delphi es posible construir consensos para mejorar la heterogeneidad de criterios en la asignación de órganos para trasplante renal entre los médicos adscritos a los servicios de Nefrología y Cirugía en seis centros hospitalarios de México. Metodología: Se realizó un estudio con el método de expertos Delphi con tres fases y dos circulaciones para identificar comportamientos y tendencias con la sinergia del debate en un grupo. Se aplicó el índice de Kappa para evaluar concordancia de los resultados. Resultados: Los resultados de la primera circulación muestran la heterogeneidad de criterios para la asignación de órganos de donador fallecido dentro de cada hospital y de los seis hospitales comparados entre si. Con los resultados de la segunda circulación en cuatro hospitales aumentó el consenso para la elección tanto del primer como del segundo receptor. El cociente de Kappa muestra la habilidad de los resultados. Conclusión: Vemos necesario desarrollar un sistema de puntaje para la asignación de órganos de donador fallecido en México, en el que será conveniente incluir el HLA. El método Delphi permite conocer la prioridad de los criterios médicos para la asignación de riñones de donador fallecido, y ayuda a construir consensos que permitan a los Comités Internos de Trasplantes de México minimizar la subjetividad del personal involucrado en la asignación de órganos.

Background: The Mexican Health Law stipulated that the criteria to be taken into account for deceased donor kidney allocation should include the following: "seriousness of recipient's condition, opportunity of transplant, expected benefits, compatibility with recipient, and all other accepted medical criteria." The practical application of these criteria has been perceived by several members of transplantation committees as allowing inequity in kidney allocation. The aims of this study were to learn the opinions of transplantation committees regarding current national allocation policies, and to obtain their opinions about the advantages of a point-score system.

Background: The National Transplant Center in Mexico has ruled that deceased-donor kidney allocation is a function of each hospital's Internal Transplant Committee. The aim of this study was to compare and analyze results for of the traditional method and a point-score system in the allocation of deceased patient's kidneys. Methods: The 12 major kidney transplant centers in the country having a deceased-donor program were invited to participate. Only 3 of them replied to the invitation during 2010. A point-score system was proposed to them, comprising blood group, waiting list time, HLA type, and donor and recipient ages. Once the final recipient was chosen, an explanation of reasons for the choice was requested. Thirty-eight transplants were presented. Kappa coefficient was used to measure degree of agreement in both allocation systems. Organs donated for transplantation came from patients between 4 and 54 years old, including 52% female, 52% O+ blood type, 31% A+, and 11% B+, 44% cranial-encephalic trauma, and 44% brain hemorrhage.

Background: Having a first- or second-degree relative with chronic kidney disease (CKD) has been reported as a risk factor for CKD development. The aim of the study was to determine the prevalence of CKD in children with a first- or second-degree relative undergoing renal replacement therapy (hemodialysis or renal transplant). Methods: A screening study was performed in asymptomatic children with a family history of CKD in a first- or second-degree relative undergoing renal replacement therapy. Informed consent was obtained in all cases. A clinical examination was performed. Blood and urine samples were obtained for serum creatinine, serum electrolytes, urinalysis, and microalbumin/creatinine ratio.

Background: There is a lack of valid health care transition readiness (HCT) scales in Spanish. Objective: To provide initial validation of the UNC TRxANSITION Scale™ among Mexican adolescents and young adults (youth) with chronic kidney disease (CKD). Methods: We used the professionally translated/back translated, provider-administered UNC TRxANSITION Scale™ (Ferris et al., 2012). This 33-question scale measures HCT in ten sub-scales including knowledge about diagnosis or treatment, diet, reproductive health, school/work, insurance, ability to self-manage and looking for new health providers. Its maximum score is 10. We enrolled 163 Mexican adolescents (48.5% females) with CKD stage≥3, mean age of 15.1years (±2.1) and whose primary language is Spanish. There were 15 patients on hemodialysis (9.2%) and 30 transplant recipients (18.4%). Results were compared to those reported in adolescents with chronic conditions from the USA.
