Relationship of hemoglobin levels with outcomes in deceased donor kidney transplant: a retrospective cohort study / Relação dos níveis de hemoglobina com desfechos em transplante renal de doador falecido: um estudo de coorte retrospectivo

ABSTRACT Introduction: Anemia is frequent in patients undergoing replacement therapy for kidney failure. Anemia in the pre- and post-transplantation period might be related to kidney transplant outcomes. The current study therefore sought to assess the relationship between anemia, delayed allograft function (DGF), chronic kidney allograft dysfunction (CAD), and death from any cause following kidney transplantation from a deceased donor. Methods: This was a retrospective study with 206 kidney transplant patients of deceased donors. We analyzed deceased donors' and kidney transplant patients' demographic data. Moreover, we compared biochemical parameters, anemia status, and medicines between DGF and non-DGF groups. Afterward, we performed a multivariate analysis. We also evaluated outcomes, such as CAD within one year and death in ten years. Results: We observed a lower frequency of pre-transplant hemoglobin concentration (Hb) but higher frequency of donor-serum creatinine and red blood transfusion within one week after transplantation in the group with DGF. In addition, there was an independent association between Hb concentration before transplantation and DGF [OR 0.252, 95%CI: 0.159-0.401; p < 0.001]. There was also an association between Hb concentration after six months of kidney transplantation and both CAD [OR 0.798, 95% CI: 0.687-0.926; p = 0.003] and death from any cause. Conclusion: An association was found between pre-transplantation anemia and DGF and between anemia six months after transplantation and both CAD and death by any cause. Thus, anemia before or after transplantation affects the outcomes for patients who have undergone kidney transplantation from a deceased donor.

RESUMO Introdução: A anemia é frequente em pacientes submetidos à terapia substitutiva para insuficiência renal. A anemia nos períodos pré e pós-transplante pode estar relacionada aos desfechos do transplante renal. Portanto, o presente estudo buscou avaliar a relação entre anemia, função retardada do enxerto (FRE), disfunção crônica do enxerto renal (DCE) e óbito por qualquer causa após transplante renal de doador falecido. Métodos: Este foi um estudo retrospectivo com 206 pacientes transplantados renais de doadores falecidos. Analisamos dados demográficos de doadores falecidos e pacientes transplantados renais. Além disso, comparamos parâmetros bioquímicos, status de anemia e medicamentos entre os grupos FRE e não-FRE. Posteriormente, realizamos uma análise multivariada. Também avaliamos desfechos, como DCE em um ano e óbito em dez anos. Resultados: Observamos menor frequência de concentração de hemoglobina (Hb) pré-transplante, mas maior frequência de creatinina sérica do doador e transfusão de hemácias no período de uma semana após o transplante no grupo FRE. Além disso, houve associação independente entre a concentração de Hb antes do transplante e a FRE [OR 0,252; IC 95%: 0,159-0,401; p < 0,001]. Houve também associação entre a concentração de Hb após seis meses de transplante renal e ambos, DCE [OR 0,798; IC95%: 0,687-0,926; p = 0,003] e óbito por qualquer causa. Conclusão: Encontrou-se uma associação entre anemia pré-transplante e FRE e entre anemia seis meses após o transplante e ambos, DCE e óbito por qualquer causa. Assim, a anemia antes ou após o transplante afeta os desfechos de pacientes que foram submetidos a transplante renal de doador falecido.

Causas de muerte de los fallecidos en hemodiálisis iterada

Introducción: La hemodiálisis es la terapia de remplazo renal más utilizada en Latinoamérica y en Cuba. Se calcula que para el año 2030 la cantidad de pacientes que inician el tratamiento de reemplazo renal a nivel mundial aumentará a más del 50 % con respecto al año 2010. Objetivo: Caracterizar los pacientes en tratamiento de hemodiálisis iterada. Métodos: Se realizó un estudio descriptivo, transversal, de todos los pacientes en tratamiento de HDI del Instituto de Nefrología "Dr. Abelardo Buch López" (INEF), fallecidos en el período 2013-2018. Los datos se obtuvieron del registro de fallecidos, del registro de pacientes en hemodiálisis y de la historia clínica. El procesamiento fue realizado de forma automatizada (IBM Spss 22.0). Se calcularon tasas brutas de mortalidad y fue utilizada la técnica de análisis de distribución de frecuencias. Resultados: La tasa de mortalidad del período resultó ser 20,3 por cada 100 pacientes. El 60,9 % de los pacientes fallecidos tenían entre 60 y 79 años de edad. La hipertensión arterial (HTA) fue la enfermedad de base más frecuente (55,5 %), y la comorbilidad predominante (87,3 %). El 53,6 % de los pacientes fallecidos empleaba catéter venoso central, y el 70 % tenía menos de 5 años en HD. La principal causa de muerte fue la enfermedad cardiovascular (46,4 %). Conclusiones: En el INEF la mortalidad en hemodiálisis se comportó de manera estable. Similar a otros reportes de servicios de hemodiálisis, los fallecidos se caracterizaron en su mayoría por tener catéter venoso central para hemodiálisis y menos de cinco años en el tratamiento. Las causas de muerte presentaron el mismo patrón que las reportadas en análisis nacionales e internacionales.

Introduction: Hemodialysis is the most used renal replacement therapy in Latin America and in Cuba. It is estimated that by the year 2030 the number of patients starting therapy worldwide will increase to more than 50% compared to 2010. Objectives: To characterize the patients undergoing iterated hemodialysis treatment. Methods: A descriptive, cross-sectional study of all patients undergoing repeated hemodialysis treatment, who deceased in the period 2013-2018 was carried out at Dr. Abelardo Buch López Institute of Nephrology. The processing was done in an automatically (IBM Spss 22.0). Gross mortality rates were calculated and the frequency distribution analysis technique was used. Results: The mortality rate for the period was 20.3 per 100 patients. 60.9% of the deceased patients were between 60 and 79 years of age. Arterial hypertension was the most frequent underlying disease (55.5%), and the predominant comorbidity (87.3%). 53.6% of the deceased patients used a central venous catheter, and 70% had been on hemodialysis for less than 5 years. The main cause of death was cardiovascular disease (46.4%). Conclusions: At Dr. Abelardo Buch López Institute of Nephrology mortality in hemodialysis behaved in a stable manner. Similar to other reports of hemodialysis services, the deceased were mostly characterized by having a central venous catheter for hemodialysis and less than five years in treatment. The causes of death showed the same pattern as those reported in national and international analyses.

Sobrevida de pacientes submetidos ao transplante hepático com enxerto de doador vivo é melhor em comparação com doador falecido — uma revisão sistemática e meta-análise / Better living donor liver transplantation patient survival compared to deceased donor — a systematic review and meta-analysis

ABSTRACT Background Deceased donor liver transplantation (DDLT) is the first choice, but living donor transplantation (LDLT) is an alternative to be considered in special situations, such as lack of donated organs and emergencies. So far, there is no consensus on which transplantation method provides better survival and fewer complications, which is still an open point for discussion. Methods This meta-analysis compared the 1, 3, and 5-year patient and graft survival rates of LDLT and DDLT. We included studies published from April-2009 to June-2021 and adopted the generic model of the inverse of variance for the random effect of hazard ratios. The adequacy of the studies was determined using the Newcastle-Ottawa Scale — NOS (WELLS). Results For patient survival analysis, we included a total of 32,258 subjects. We found a statistically significant better survival for the LDLT group at 1, 3 and 5 years, respectively: 1.35 HR (95%CI 1.10—1.66, P=0.005), 1.26 HR (95%CI 1.09—1.46, P=0.002) and 1.27 HR (95%CI 1.09—1.48, P=0.002). Our meta-analysis evaluated a total of 21,276 grafts. In the overall analysis, the 1-year survival was improved in favor of the LDLT group (1.36 HR, 95%CI 1.16—1.60, P<0.0001), while the 3-year survival (1.13 HR, 95%CI 0.96—1.33, P<0.13), and 5 (0.99 HR, 95%CI 0.74—1.33, P<0.96), did not differ significantly. Conclusion This metanalysis detected a statistically significant greater 1-, 3- and 5-years patient survival favoring LDLT compared to DDLT as well as a statistically significant difference better 1-year graft survival favoring the LDLT group.

RESUMO Contexto O transplante de fígado com doador falecido é a primeira escolha, mas o transplante de doador vivo é uma alternativa a ser considerada em situações especiais, como falta de órgãos doados e emergências. Até o momento, não há consenso sobre qual método de transplante proporciona melhor sobrevida e menos complicações, sendo, ainda, um ponto em aberto para discussão. Métodos Esta meta-análise comparou as taxas de sobrevida de pacientes e enxertos de 1, 3 e 5 anos de transplante de doador vivo e transplante de fígado com doador falecido. Incluímos estudos publicados de abril de 2009 a junho de 2021 e adotamos o modelo genérico do inverso da variância para o efeito aleatório das razões de risco. A adequação dos estudos foi determinada por meio da Escala de Newcastle-Ottawa — NOS (WELLS). Resultados Para análise de sobrevida do paciente, incluímos um total de 32.258 indivíduos. Encontramos uma melhor sobrevida estatisticamente significativa para o grupo de transplante de fígado de doador vivo em 1, 3 e 5 anos, respectivamente: 1,35 HR (IC95% 1,10—1,66, P=0,005), 1,26 HR (IC95% 1,09—1,46, P=0,002) e 1,27 HR (IC95% 1,09—1,48, P=0,002). Nossa meta-análise avaliou um total de 21.276 enxertos. Na análise geral, a sobrevida em 1 ano foi melhorada em favor do grupo de transplante de doador vivo (1,36 HR, IC95% 1,16—1,60, P<0,0001), enquanto a sobrevida em 3 anos (1,13 HR, IC95% 0,96—1,33, P<0,13) e 5 (0,99 HR, IC95% 0,74—1,33, P<0,96), não diferiram significativamente. Conclusão Esta meta-análise detectou uma sobrevida estatisticamente significativa maior do paciente em 1, 3 e 5 anos favorecendo o transplante de doador vivo em comparação com o transplante de fígado com doador falecido, bem como uma diferença estatisticamente significativa melhor na sobrevida do enxerto em 1 ano favorecendo o grupo de transplante de doador vivo.

Supervivencia del paciente trasplantado y del injerto renal en una cohorte retrospectiva en México / Transplant patient and kidney graft survival in a retrospective cohort in Mexico

Introducción: el conocimiento de la funcionalidad del injerto y la supervivencia del paciente es fundamental para valorar el éxito del trasplante renal. Objetivo: determinar la supervivencia de los pacientes trasplantados por tipo de donante y la funcionalidad de los injertos renales en una cohorte en México. Material y métodos: cohorte de trasplante renal de 2013 a 2017 en México. Se analizaron 790 pacientes seguidos por un año para valorar la supervivencia de los pacientes trasplantados por tipo de donante y la funcionalidad de los injertos renales. Para ello se usaron medidas de tendencia central y dispersión, así como tablas de supervivencia de Kaplan-Meier con SPSS, versión 25. Resultados: de los 790 pacientes, 518 fueron de donante vivo (65.56%) con supervivencia del paciente de 97.88% y de funcionalidad del injerto de 93.24% a 12 meses de seguimiento; 272 pacientes recibieron el injerto de donante fallecido con supervivencia del paciente de 91.18% y funcionalidad del injerto renal de 84.19%. Conclusiones: aún existe una diferencia de casi 5% en la supervivencia del paciente receptor de un donante vivo en referencia con un donante fallecido. Para la funcionalidad del injerto renal esta diferencia es > 7%. La donación cadavérica ha aumentado; sin embargo, incluso en cifras bajas es de aproximadamente el 35% en México

Background: Knowledge of the functionality of the graft and patient survival is essential to assess the success of kidney transplantation. Objective: To determine the survival of transplanted patients by type of donor and the functionality of kidney grafts in a cohort in Mexico. Material and methods: Kidney transplant cohort from 2013 to 2017 in Mexico. 790 patients followed up for one year were analyzed to assess the survival of transplanted patients by type of donor and the functionality of kidney grafts. For this, measures of central tendency and dispersion were used, as well as Kaplan-Meier survival tables with SPSS, version 25. Results: Out of the 790 patients, 518 were from living donors (65.56%) with patient survival of 97.88% and graft function of 93.24% at 12 months of follow-up; 272 patients received the graft from a deceased donor with patient survival of 91.18% and renal graft function of 84.19%. Conclusions: There is still a difference of almost 5% in the survival of the recipient patient from a living donor compared to a deceased donor. For the functionality of the kidney graft, this difference is > 7%. Cadaveric donation has increased; however, even at low figures is of approximately 35% in Mexico

Distribution characteristics and risk factors of fungal infection after liver transplantation from deceased donation / 中华器官移植杂志

Objective:To explore the pathogenic characteristics and related risk factors of fungal infection after liver transplantation(LT)from deceased donation and provide rationales for formulating optimal control strategies.Methods:From February 2019 to September 2020, clinical data were retrospectively reviewed for 187 recipients after LT from deceased donation.Univariate and multiple Logistic regression analyses were performed for determining the independent risk factors of postoperative fungal infection.Results:Among 187 LT cases, 26 cases had postoperative fungal infection with a mortality rate of 46.2%(12/26). Lung was the most common fungal infection site, accounting for 80.8%(21/26). The most common pathogenic bacteria of fungal infection were Candida albicans, accounting for 53.3%(16/30). Multiple Logistic regression analysis indicated that operative duration ≥8 h( OR=3.610, 95% CI: 1.079-12.081, P=0.037), re-operation( OR=39.234, 95% CI: 3.512-438.258, P=0.003)and intensive care unit(ICU)retention time ≥7 d( OR=10.070, 95% CI: 3.480-29.140, P=0.002)were independent risk factors of postoperative fungal infection. Conclusions:Postoperative fungal infection is a serious threat to the prognosis of recipients of LT from deceased donation.Minimizing operative duration on the basis of ensuring quality of surgery, strictly grasping the indications for re-operation and transferring out of ICU in early postoperative period may help to lower the risks of fungal infection after LT from deceased donation.

Short-term outcome of kidney transplantation from deceased donors with nephrolithiasis / 中南大学学报(医学版)

Objective: Shortage of kidney allografts is a major barrier to end-stage renal disease patients receiving kidney transplantation, and it is necessary to enlarge the donor pool and find better ways of using available allografts. The global incidence of nephrolithiasis is increasing, nephrolithiasis affects approximately 10％ of adults worldwide, and it also affects the kidney donors. However, there is little information about the use of cadaveric kidney allografts with nephrolithiasis. This study aims to evaluate the safety and outcome of kidney transplantation with allografts from the deceased donors with nephrolithiasis. Methods: A total of 520 deceased donors who was at least 10 years old, and 945 adult recipients with single kidney transplantation at the Department of Kidney Transplantation, the Second Xiangya Hospital from 2016 to 2020 were included in this study. The donors were divided into 2 groups according to nephrolithiasis diagnoses: The donors with nephrolithiasis (D+) and the donors without nephrolithiasis (D?). The recipients were assigned into 3 groups according to their donors and the allografts they received: The allografts from donors without nephrolithiasis (D?K?), the allografts without nephrolithiasis from donors with nephrolithiasis (D+K?), and the allografts with nephrolithiasis (D+K+). The demographic and clinical data of enrolled subjects were retrospectively analyzed. The allograft discard ratio between different donors were analyzed. The one-year survival of allografts and recipients, as well as the allograft function and the complications of kidney transplantation were compared. Results: Fifty out of 520 donors had nephrolithiasis, and the nephrolithiasis incidence was 9.6％. We recovered 1040 kidneys, and total discard rate was 4.4％ (46/1040). The D+ group had a rate of 7％ discard. The donors with kidney discard accounted for 12％ in the D+ group, and this was higher than that of donors in the D? group (5.1％, P<0.05). The total incidence of delayed graft function (DGF) was 7.5％, and there were no significant differences in the incidence of DGF in recipients among the D?K?, D+K?, and D+K+ group (7.5％ vs 6.5％ vs 8.2％, P>0.05). During the one-year follow-up, 8 allografts lost function and 19 recipients died with a functional allograft. Recipients in the D?K?, D+K?, and D+K+ groups also had no significant difference between a one-year allograft and patient survival rate (P>0.05). However, recipients in the D+K+ group had a higher level of serum creatinine [(139.2±62.46) μmol/L vs (117.19±51.22) μmol/L, P<0.05] and lower estimated glomerular filtration rate [eGFR; (56.67±23.31) mL/(min·1.73 m?2) vs (66.86±21.90) mL/(min·1.73 m?2), P<0.05] compared with recipients in the D?K? group at 12 months after transplantation. During the first year after transplantation, 4 recipients developed urolithiasis, and recipients who received allografts from the D+ group donors had a higher incidence of urolithiasis than those who received allografts from the D? group donors (2.2％ vs 0.2％, P<0.05). There were no significant differences in the incidence of urinary tract infections and ureteral strictures at 1 year between recipients of D+ and D? donors (both P>0.05).Conclusion: The cadaveric kidney allografts with nephrolithiasis could be safely used for transplantation, and the short-term outcome is acceptable. However, nephrolithiasis in donors may increase the rate of kidney discard, disturb the short-term function of allografts, and increase the risk of urolithiasis in recipients. Further research with a long-term study is needed to verify the long-term outcome of kidney transplantation using cadaveric kidney allografts with nephrolithiasis.

Utilidad de la prueba de la lactato deshidrogenasa en fallecidos cubanos con sida y neumonía por Pneumocystis jirovecii

RESUMEN Introducción: La neumonía por Pneumocystis jirovecii es una de las enfermedades de mayor impacto negativo en los pacientes con sida. La imposibilidad de cultivar el agente que la provoca, así como su cuadro clínico inespecífico y el alto costo de los métodos diagnósticos moleculares, señalan la necesidad de otras alternativas para su diagnóstico. La prueba de la lactato deshidrogenasa representa una opción a considerar. Objetivo: Demostrar la utilidad de la prueba de la lactato deshidrogenasa como diagnóstico de la Pneumocystis jirovecii en fallecidos cubanos por sida. Métodos: Se realizó un estudio de casos y controles (25 casos [Pneumocystis jirovecii] y 30 controles [compuestos por tres grupos: tuberculosis, linfoma y neumonía bacteriana, respectivamente]) en fallecidos cubanos a los que se realizó la autopsia desde enero de 1996 a diciembre de 2016. Se utilizaron cinco rangos de corte para buscar el valor óptimo de la prueba. Resultados: En el presente estudio existen diferencias altamente significativas entre los pacientes analizados (casos y controles) y entre los restantes individuos que componen los controles con respecto al del linfoma. El rango de corte óptimo para la prueba de la lactato deshidrogenasa fue (550-<800 U/I) con sensibilidad de 80 % y especificidad de 63 %. La razón de disparidad (OR) demostró que existe 6,91 veces más probabilidades que los pacientes por Pneumocystis jirovecii tengan las cifras de LDH mayor que los pacientes controles. Conclusiones: Este trabajo aporta evidencias científicas del rol de la prueba de la lactato deshidrogenasa como herramienta complementaria para el diagnóstico de la Pneumocystis jirovecii.

ABSTRACT Introduction: Pneumocystis jirovecii pneumonia is one of the diseases causing the greatest negative impact on AIDS patients. The impossibility of culturing its causative agent, its unspecific clinical presentation and the high cost of molecular diagnostic methods, make it necessary to find other diagnostic alternatives. The lactate dehydrogenase test is an option to be considered. Objective: Demonstrate the usefulness of the lactate dehydrogenase test to diagnose Pneumocystis jirovecii in Cuban patients deceased with AIDS. Methods: A case-control study was conducted (25 cases [Pneumocystis jirovecii] and 30 controls [distributed into three groups: tuberculosis, lymphoma and bacterial pneumonia, respectively]) of Cuban deceased patients undergoing post-mortem examination from January 1996 to December 2016. Five cutoff ranges were used to find the optimal value of the test. Results: Highly significant differences were found between the patients analyzed (cases and controls) and between the remaining individuals making up the controls with respect to the one with lymphoma. The optimal cutoff range for the lactate dehydrogenase test was 550-<800 U/I, with 80% sensitivity and 63% specificity. The odds ratio (OR) showed that probabilities are 6.91 times greater that Pneumocystis jirovecii pneumonia patients have higher LDH figures than control patients. Conclusions: Scientific evidence is contributed of the role of the lactate dehydrogenase test as a complementary tool in the diagnosis of Pneumocystis jirovecii.

Características y causas de muerte de pacientes fallecidos con enfermedad renal crónica. Cuba 2011-2016 / Deceased patients with chronic kidney disease. Characteristics and causes in Cuba during 2011-2016

Introducción: La morbimortalidad por enfermedad renal crónica (ERC) ha presentado en las dos últimas décadas un incremento desconcertante. En Cuba, aunque la mortalidad por esta causa ha tenido un comportamiento estable, la incidencia y la prevalencia se mantienen elevadas. Objetivo: Caracterizar los pacientes fallecidos con ERC según variables demográficas, causas de muerte y otras variables seleccionadas. Material y Métodos: Estudio descriptivo, transversal. El universo de estudio estuvo constituido por todos los fallecidos del país en el período, en cuyos certificados de defunción se incluyó entre una de las causas, la ERC. La información fue obtenida de las bases de datos de mortalidad de la Dirección Nacional de Registros Médicos y Estadísticos de Salud del MINSAP. Procesamiento de forma automatizada (SPSS versión 22.0). Fueron calculadas las frecuencias absolutas y relativas. Resultados: La frecuencia global de pacientes fallecidos se incrementó de forma mantenida y resultó mayor en la provincia La Habana (23,6 por ciento). La media de la edad fue de 70 años. Prevaleció el sexo masculino, el color de piel blanco y el grupo de edad de 80 años y más. Los porcentajes más altos según la causa básica de muerte correspondieron a enfermedad renal hipertensiva y Diabetes Mellitus. Conclusiones: Los fallecidos con ERC son mayormente hombres, de piel blanca, y con edades avanzadas. Las principales causas de muerte son la enfermedad hipertensiva y la Diabetes Mellitus(AU)

Introduction: Chronic kidney disease (CKD) has increased at an alarming rate worldwide over the last two decades. Although mortality due to CKD has registered stable behavior in Cuba, its prevalence and incidence are showing higher rates. Objective: To describe the main demographic features of deceased patients with CKD in Cuba, the causes of death and other variables during the period 2011-2016. Material and Methods: A descriptive cross-sectional study was conducted. The study universe included all deceased patients in Cuba during the period mentioned. CKD was listed on their death certificates as one of the causes of death. The information used was obtained from the mortality database available on the National Directorate of Medical Records and Health Statistics of the Cuban Ministry of Public Health. Data was processed using SPSS version 22.0. Absolute and relative frequencies were calculated. Results: The global frequency of deceased patients showed a steady increase. Havana was the city that presented the highest percentage (23,6 percent). Nonetheless, the rest of the cities showed an increased frequency rate. The median age was 70 years. The male gender prevailed over the female one as well as white ethnicity and the 80 years and over age group. Regarding the cause of death, the highest percentages corresponded to hypertensive kidney disease and Diabetes Mellitus. Conclusions: Most of the deceased patients with CKD are male, white and at advanced ages. The main causes of death are hypertensive disease and Diabetes Mellitus(AU)

The sum of kidney donor profile index and estimated post-transplant survival scale and their correlation with egfr decline in deceased donor kidney recipients

Background: The impact of donor quality on post-kidney transplant survival may vary by candidate condition. Objective: Analyzing the combined use of the Kidney Donor Profile Index (KDPI) and the estimated post-transplant survival (EPTS) scale and their correlation with the estimated glomerular filtration rate (eGFR) decline in deceased-donor kidney recipients (DDKR). Methods: This was a retrospective, observational cohort study. We included DDKRs between 2015 and 2017 at a national third-level hospital. Results: We analyzed 68 DDKR. The mean age at transplant was 41 ± 14 years, 47 (69%) had sensitization events, 18 (26%) had delayed graft function, and 16 (23%) acute rejection. The graft survival at 12 and 36 months was 98.1% (95% CI 94-100) and 83.7% (95% CI 65-100), respectively. The Pearson correlation coefficient between the percentage reduction in the annual eGFR and the sum of EPTS and KDPI scales was r = 0.61, p < 0.001. The correlation coefficient between the percentage reduction in the annual eGFR and the EPTS and KDPI scales separately was r = 0.55, p < 0.001, and r = 0.53, p < 0.001, respectively. Conclusions: The sum of EPTS and KDPI scales can provide a better donor-recipient relationship and has a moderately positive correlation with the decrease in eGFR in DDKR.

Fatality due to COVID-19 associated with risk factors in the province of Buenos Aires, Argentina, 2020 / Letalidad por covid-19 asociada a factores de riesgo en la provincia de buenos aires, argentina, 2020

RESUMEN INTRODUCCIÓN : El objetivo principal fue evaluar el riesgo de defunción en pacientes con diagnóstico confirmado de COVID-19 según la presencia de uno o más factores de riesgo. MÉTODOS : Estudio transversal, descriptivo y correlacional de personas mayores de 18 años, residentes de la provincia de Buenos Aires, con diagnóstico de COVID-19 confirmado por laboratorio o criterio clínico-epidemiológico que hayan iniciado síntomas entre marzo y diciembre de 2020 (n = 622 084). Se utilizó información de fuente secundaria. Se consideraron cuatro escenarios de análisis con base en la calidad del dato y la condición del paciente. RESULTADOS : Se notificaron 21 706 casos fallecidos (letalidad 3,5%). La mayoría de los fallecidos tenía edad avanzada (72,8 ± 13,8 años en los fallecidos versus 41,2 ± 15,2 años en los no fallecidos) y eran de sexo masculino (56% versus 44%, p<0,05). Según el modelo multivariado, la edad de 60 años o más resultó ser el factor de mayor riesgo (razón de momios OR, por su sigla en inglés: 8,1), seguida por la hepatopatía crónica (OR: 2,3). DISCUSIÓN : Los resultados muestran que la mayoría de los casos sintomáticos tuvieron una evolución favorable. La tasa de letalidad provincial es similar a la tasa nacional. Los factores de riesgo que resultaron relevantes se condicen con estudios realizados tanto en Argentina como en otros países. Si bien tener 60 años o más fue el mayor factor de riesgo, la presencia concomitante de enfermedades crónicas no transmisibles también contribuyó al agravamiento de la infección por COVID-19. Esta información es relevante para pensar políticas de salud en dicha población.

ABSTRACT INTRODUCTION . The main objective was to evalúate the risk of death in patients according to the presence of one or more risk factors in confirmed cases of COVID-19. METHODS : Cross-sectional, descriptive, correlational study of COVID-19 cases in people over 18 years of age, residents of the Province of Buenos Aires, confirmed by laboratory or clinical-epidemiological criteria that have started symptoms from March to December 2020 (n = 622,084). Secondary source information. Four analysis scenarios were considered taking into account the quality of the data and the patient's condition. RESULTS : 21,706 deceased cases were reported (3.5% fatality rate). Age (72.8 ± 13.8 vs 41.2 ± 15.2) and male patients (56% vs 44%; p <0.05) were higher in the deceased. According to the multivariate model, being 60 years or older was the highest risk factor (OR: 8.1) followed by chronic liver disease (OR: 2.3). DISCUSSION : The results show that most of the symptomatic cases had a favorable evolution. The provincial fatality rate is similar to the national rate. The risk factors that were relevant are consistent with studies carried out both in our country and in other countries. Although being 60 years or older was the greatest risk factor, most of the CNCDs analyzed also contributed to the COVID-19 infection becoming worse. This information is relevant to think about health policies for this population.

Overview of global organ donation and transplantation in 2020 / 器官移植

Objective At present, the novel coronavirus pneumonia (COVID-19) pandemic is still raging in certain regions around the globe, and the prevention and control of the pandemic should be strengthened. Under the challenges of respective social environment and allocation of medical resources, and support from the inertia and inherent productivity of the system on which the industry depends, extensive attempts are being delivered to push forward the work of organ donation and transplantation in each country. Under the guidance of national experts and committee members, Shanxi Provincial Human Organ Procurement and Allocation Service Center was established on August 28, 2018 approved by the former Shanxi Provincial Health and Family Planning Commission. It is the only independent non-profit medical institution in Shanxi Province. In this article, the system construction of citizen's organ donation and transplantation fitting national and provincial conditions was further explored according to the data analysis of organ donation and transplantation in the United States and Spain during the COVID-19 pandemic combined with the implementation of organ donation work in Shanxi Provincial Human Organ Procurement and Allocation Service Center.

Hallazgos radiológicos de la neumonía por Pneumocystis jirovecii en fallecidos cubanos con VIH/sida / Radiological findings of Pneumocystis jirovecii pneumonia in Cuban deceased HIV / AIDS patients

Introducción: La neumonía por Pneumocystis jirovecii (PcP) es una de las enfermedades más frecuentes en los pacientes con VIH/sida y provoca una alta morbilidad y mortalidad. La radiología juega un papel fundamental para su diagnóstico presuntivo. Objetivo: Describir los hallazgos radiológicos de neumonía por Pneumocystis jirovecii en una serie de casos de fallecidos cubanos por VIH/sida, y relacionarlos con el estado inmunológico de los pacientes. Métodos: Se realizó el estudio de una serie de 69 fallecidos por sida con PcP en el Instituto de Medicina Tropical Pedro Kourí desde enero de 1996 a enero de 2014. El diagnóstico de la PcP se confirmó por estudios anatomopatológicos mediante la observación de estructuras compatibles con el hongo. Resultados: De los 69 casos del estudio, 57 (82,6 por ciento) presentaron alteraciones en la radiografía de tórax. De ellos, 44 (77,2 por ciento) y 13 (22,8 por ciento) presentaron un patrón radiológico típico y atípico de la PcP, respectivamente. En 12 (17,4 por ciento) fallecidos la radiografía de tórax fue normal. En 76,8 por ciento de los casos se detectó niveles de linfocitos T CD4+ inferior a 200 cél/ 956;L. La relación entre el patrón radiológico y el estado inmunológico de los fallecidos analizados no fue significativa. Conclusiones: Los hallazgos radiológicos descritos en los fallecidos cubanos por sida con PcP son similares a los informados en la literatura internacional. Sin embargo, el diagnóstico de la PcP no debe excluirse en pacientes con radiografías de tórax normales o con patrones atípicos que presenten un cuadro clínico sugestivo de la enfermedad(AU)

Introduction: Pneumocystis jirovecii pneumonia (PcP) is one of the most common diseases among HIV / AIDS patients, causing great morbidity and mortality. Radiology plays a fundamental role in its presumptive diagnosis. Objective: Describe the radiological findings of Pneumocystis jirovecii pneumonia in a series of Cuban deceased HIV / AIDS patients and relate them to the patients' immune status. Methods: A study was conducted of a series of 69 deceased AIDS patients with PcP at Pedro Kourí Tropical Medicine Institute from January 1996 to January 2014. PcP diagnosis was confirmed through anatomopathological studies based on observation of structures compatible with the fungus. Results: Of the 69 study cases, 57 (82.6 percent) presented alterations in their chest radiographs. Of these, 44 (77.2 percent) and 13 (22.8 percent) followed a typical and atypical radiological pattern, respectively. In 12 deceased patients (17.4 percent) chest radiography was normal. In 76.8 percent of the cases, levels of T CD4+ lymphocytes were below 200 cell/ml. The relationship between the radiological pattern and the immune status of the deceased patients analyzed was not significant. Conclusions: The radiological findings described for Cuban deceased AIDS patients with PcP are similar to those reported in the international literature. However, PcP diagnosis should not be excluded in patients with normal chest radiographs or atypical patterns who present a clinical status suggestive of the disease(AU)

Application of hypothermic machine perfusion in the renal transplantation from deceased donor with high-risk delayed graft function / 器官移植

Objective To evaluate the clinical effect of hypothermic machine perfusion (HMP) in the storage of renal grafts from deceased donor (DD) with high-risk delayed graft function (DGF). Methods Clinical data of 52 donors with high-risk DGF were collected in this prospective randomized controlled study. Two renal grafts from each donor were randomly divided into the HMP group (n=52) and static cold storage (SCS) group (n=52). In the HMP group, the renal grafts were stored by LifePort under HMP, whereas the renal grafts in the SCS group were preserved in University of Wisconsin solution (UW solution). The incidence of DGF and primary nonfunction (PNF) after renal transplantation was statistically compared between two groups. The recovery of renal graft function, the survival rates of the recipients and renal grafts within postoperative 1 year were observed in two groups. Results The incidence of DGF in the HMP group was 4%(2/52), significantly lower than 17% (9/52) in the SCS group (P < 0.05). No PNF was reported in the HMP group and 1 case of PND was noted in the SCS group, the difference was not statistically significant (P > 0.05). The recovery time of graft function of the recipients in the HMP and SCS groups were (7.2±0.6) d and (7.7±1.0) d with no statistical significance (P > 0.05). In the HMP group, the urine volume of the recipients on the day of operation, postoperative 1 and2 d was significantly larger than that in the SCS group (all P < 0.05). In the HMP group, the levels of serum creatinine at each time point after operation were significantly lower than those in the SCS group (all P < 0.05). The 1-year survival rates of the recipient and kidney were 98.1%, 92.3% and 100%, 96.2% in the HMP and SCS groups with no statistical significance (all P > 0.05). Conclusions HMP can significantly reduce the incidence of DGF after renal transplantation from DD with high-risk DGF and promote the early recovery of graft function.

Symptoms of Influenza A (H1N1) are similar to those of the seasonal flu. First laboratory confirmed Influenza A (H1N1) case of India was reported from Hyderabad on 16th May 2009.Methods: The study was retrospective descriptive, record-based study and carried in deceased of Influenza A (H1N1) who were admitted in Jawaharlal Nehru Medical College and Hospital, Ajmer, Rajasthan, India from 01 January 2016 to 31 December 2018.Results: A total 1524 suspected cases were screened for Influenza A (H1N1) at JLN Medical College and Hospital, Ajmer during the period from 1st January 2016 to 31st December 2018. 294 cases were diagnosed as Influenza A (H1N1) positive and 44 died. Majority 25 (56.81%) were belonged to rural area and 30 (68.18%) females died as compare to 14 (31.18%) male.Conclusions: Incidence and mortality is common throughout the year but it more in winter months. Mortality is high in age group of 50 years and above, females and rural area. IEC activities should be throughout year.

Lesión aterosclerótica en arterias coronarias de fallecidos por muerte violenta en edad pediátrica / Atherosclerotic coronary arteries lesion in pediatric violent deaths

Introducción: La aterosclerosis es una enfermedad que comienza con la unión del óvulo y el espermatozoide, se desarrolla con el paso del tiempo en estrecha relación con estilos de vida, y está entre las primeras causas básicas de muerte a nivel mundial. Hay que conocerla desde sus inicios para poder prevenir y enfrentar sus temibles consecuencias. Objetivo: Caracterizar la lesión aterosclerótica en las arterias coronarias de fallecidos por muerte violenta en edad pediátrica. Métodos: Se realizó un estudio observacional, transversal de 32 fallecidos en edad pediátrica, con autopsias médico legales, de ellos se analizaron cualitativa y cuantitativamente sus arterias coronarias mediante el sistema aterométrico. Resultados: Se presentaron estrías adiposas y placas fibrosas de los tres sectores coronarios principales en 32 sujetos. Las placas graves no estuvieron presentes en el estudio en ninguno de los grupos. Las estrías adiposas, se constataron desde edades tempranas y alcanzaron mayores valores según aumentó la edad. De los tres sectores arteriales, el que más estrías adiposas y placas fibrosas presentó fue la descendente anterior. Conclusiones: Desde etapas muy tempranas de la vida se encuentran evidencias irrefutables de lesiones ateroscleróticas, que se intensifican a medida que avanza la edad. La arteria más afectada resultó ser la descendente anterior(AU)

Introduction: Atherosclerosis is a disease that begins with the union of the ovum and sperm. It develops over time in close relationship with lifestyles, and it is among the first basic causes of death worldwide. In order to prevent and face its terrible consequences it is necessary to learn about it from the beginning. Objective: To characterize the atherosclerotic coronary arteries in pediatric violent death. Methods: This is an observational, cross-sectional study focused on 32 pediatric deaths. We reviewed the legal medical autopsies. The coronary arteries were analyzed qualitatively and quantitatively by the atheometric system. Results: Adipose striae and fibrous plaques of the three main coronary sectors were presented in these 32 subjects. The severe plaques were not present in the study in any of the groups. We found adipose striae from an early age and reached higher values as age increased. The anterior descending arterial sector had the most fat streaks and fibrous plaques. Conclusions: This study found irrefutable evidence of atherosclerotic lesions from very early stages of life, which intensify as age advances. The most affected artery was the anterior descending artery(AU)

A liberação de citocinas induzida pela morte cerebral não está associada à disfunção primária do enxerto: um estudo de coorte / Brain death-induced cytokine release is not associated with primary graft dysfunction: a cohort study

RESUMO Objetivo: Examinar a associação entre os níveis de citocinas no plasma do doador e o desenvolvimento de disfunção primária do enxerto de órgãos transplantados a partir de doadores falecidos. Métodos: Foram incluídos no estudo de forma prospectiva 17 doadores falecidos e os respectivos 47 pacientes receptores de transplante. Os receptores foram divididos em dois grupos: grupo 1, de pacientes que desenvolveram disfunção primária do enxerto, e grupo 2, de pacientes que não desenvolveram disfunção primária do enxerto. Os níveis de TNF, IL-6, IL-1β, e IFN-γ, avaliados por meio de ELISA, foram comparados entre os grupos. Resultados: Obtiveram-se 69 órgãos, sendo realizados 48 transplantes. Os níveis plasmáticos de citocinas nos doadores não diferiram entre os grupos (em pg/mL): TNF no grupo 1, com 10,8 (4,3 - 30,8) versus no grupo 2, com 8,7 (4,1 - 33,1), com valor de p = 0,63; IL-6 no grupo 1: 1.617,8 (106,7 - 5.361,7) versus no grupo 2: 922,9 (161,7 - 5.361,7), com p = 0,56; IL-1β, no grupo 1: 0,1 (0,1 - 126,1) versus no grupo 2: 0,1 (0,1 - 243,6), com p = 0,60; e IFN-γ, no grupo 1: 0,03 (0,02 - 0,2) versus no grupo 2: 0,03 (0,02 - 0,1), p = 0,93). Obtivemos resultados similares ao examinar separadamente os casos de transplante renal. Conclusão: Nesta amostra de receptores de transplante, os níveis plasmáticos das citocinas TNF, IL-6, IL-1β e IFN-γ nos doadores não se associaram com o desenvolvimento de disfunção primária do enxerto.

ABSTRACT Objective: To examine the association between donor plasma cytokine levels and the development of primary graft dysfunction of organs transplanted from deceased donors. Methods: Seventeen deceased donors and the respective 47 transplant recipients were prospectively included in the study. Recipients were divided into two groups: group 1, patients who developed primary graft dysfunction; and group 2, patients who did not develop primary graft dysfunction. Donor plasma levels of TNF, IL-6, IL-1β, and IFN-γ assessed by ELISA were compared between groups. Results: Sixty-nine organs were retrieved, and 48 transplants were performed. Donor plasma cytokine levels did not differ between groups (in pg/mL): TNF, group 1: 10.8 (4.3 - 30.8) versus group 2: 8.7 (4.1 - 33.1), p = 0.63; IL-6, group 1: 1617.8 (106.7 - 5361.7) versus group 2: 922.9 (161.7 - 5361.7), p = 0.56; IL-1β, group 1: 0.1 (0.1 - 126.1) versus group 2: 0.1 (0.1 - 243.6), p = 0.60; and IFN-γ, group 1: 0.03 (0.02 - 0.2) versus group 2: 0.03 (0.02 - 0.1), p = 0.93). Similar findings were obtained when kidney transplants were analyzed separately. Conclusion: In this sample of transplant recipients, deceased donor plasma cytokines TNF, IL-6, IL-1β, and IFN-γ were not associated with the development of primary graft dysfunction.

Hepatocellular carcinoma recurrence in living and deceased donor liver transplantation: a systematic review and meta-analysis / 中华医学杂志(英文版)

Background@#Although a number of technical problems and donor safety issues associated with living donor liver transplantation (LDLT) have been resolved, some initial clinical studies showed an increased risk of hepatocellular carcinoma (HCC) recurrence in LDLT. This meta-analysis was conducted to assess differences in tumor recurrence between LDLT and deceased donor liver transplantation (DDLT).@*Methods@#After systematic retrievals of studies about LDLT and DDLT for HCC, articles were selected with a rationale of emphasizing inter-group comparability. Results from multivariate analyses were combined and discussed together with univariate analyses. In subgroup analysis, the impact of organ allocation policy was taken into consideration.@*Results@#Seven articles were included in the meta-analysis. Overall, a salient result that emerged from the seven studies was a significant increased risk of HCC recurrence in the LDLT group than in the DDLT group (P = 0.01). The most significant increase in hazard ratio was found in studies where organs tended to be allocated to non-tumor patients.@*Conclusions@#An increased risk for HCC recurrence in LDLT as compared with DDLT patients was found. The relatively shorter preoperative observation windows in LDLT may lead to fewer cases of HCC with invasive features being screened out, which may provide a possible explanation for the high rates of HCC recurrence.

Efficacy of Nasobiliary Tubes and Biliary Stents in Management of Patients with Bile Leak after Liver Transplantation: A Systematic Review

BACKGROUND/AIMS: Bile leak is one of the most common complications of liver transplantation. The treatment options for bile leaks include conservative management, surgical re-intervention, percutaneous drainage and endoscopic drainage. We aimed to perform a systematic review to identify the efficacy of endoscopic treatment in the resolution of post-transplant bile leaks. METHODS: Two independent reviewers performed systematic literature search in PubMed, ISI Web of Science, grey literature and relevant references in May 2017. Human studies in English with documented post-liver transplant bile leaks were included. RESULTS: Thirty-four studies were included in the final analysis. The pooled efficacy of biliary stents for the resolution of post-transplant bile leaks was 82.43% compared with 87.15% efficacy of nasobiliary tubes. The efficacy of biliary stents was lower for anastomotic leaks (69.23%) compared to T-tube (90.9%) or cut-surface/ cystic duct stump related leaks (92.8%). Similarly, the efficacy of nasobiliary tube was also lower for anastomotic leaks (58.33%) compared to T-tube or cut-surface related leaks (100%). CONCLUSIONS: In this systematic review, the overall efficacy was 82.43% in biliary stent group, and 87.15% in nasobiliary tube group. Both biliary stent and nasobiliary tube were more effective in managing non-anastomotic leaks compared to anastomotic leaks.

Circuito del paciente fallecido en el Hospital Garrahan: Implementación de Gestión por procesos y plan de mejora integral / Circuit of the deceased patient at Garrahan Hospital: implementation of process management and a comprensive plan for improvement

Ante circunstancias que concluyen en el fallecimiento de los pacientes, el Hospital Garrahan (HG) debe facilitar el duelo con medidas adecuadas y apropiadas en un contexto de respeto y contención, acompañando preguntas, dudas e incertidumbres familiares, respetando valores, evitando dificultades administrativas y legales. El objetivo fue trabajar sobre el proceso del paciente fallecido para ordenar la normativa histórica, reglamentarla y documentarla agregando avances tecnológicos. Se estableció un circuito que llamamos circuito del paciente fallecido (CPF). Es un proceso que comienza en la inscripción de la defunción, traslado del paciente a la morgue hasta la entrega a la familia. Involucra al hospital de forma transversal. A través del trabajo interdisciplinario, aplicando conceptos y herramientas de gestión, se trabajó un plan de mejora en la gestión del CPF, partiendo de la disposi- ción hospitalaria vigente, adecuando el Protocolo respectivo del Ministerio de Salud del Gobierno de la Ciudad de Buenos Aires, estableciendo registros adecuados en todo el circuito. El diseño metodológico propuesto fue la planificación, desarrollo implementación de un plan de mejora en el CPF de acuerdo a gestión por procesos. Se desarrollaron las siguientes etapas: análisis de la situación de salud que generó la intervención, identificación del proceso en un mapa, identificación de problemas del CPF, revisión y análisis del proceso e implementación del plan de mejora. Este plan de mejora está sustentado en la Disposición N°238/ DME/17

When a patient dies in hospital, Garrahan Hospital should facilitate the process of mourning with adequate and appropriate measures in a context of respect and contention, providing support in case of questions, doubts, and uncertainties of the family, respecting values and avoiding administrative and legal difficulties. The aim of this project was to improve the processes related to the deceased patients organizing historical norms by establishing guidelines and documentation using new technological means. A circuit called circuit of the deceased patient (CDP) was established, consisting of a process that starts at the moment of the registration of death, followed by the transfer of the patient to the morgue, and finishing with the handing over to the family. The process involves the hospital transversally. In an interdisciplinary manner and using different management concepts and tools, a plan of improvement of the management of the CDP was developed, based on the current regulations of the hospital, adapting the protocol of the Ministry of Health of the Government of the City of Buenos Aires, establishing adequate records for the entire circuit. The proposed methodological design consisted of the planning, development, and implementation of a plan for the improvement of the CDP according to process management. The following stages were developed: analysis of the situation that led to the intervention, identification of the process on a map, identification of difficulties in the CDP, process revision and analysis and implementation of the improvement plan. The improvement plan is supported by Disposition N°238/DME/17
