Graft survival and delayed graft function with normothermic regional perfusion and rapid recovery after circulatory death in kidney transplantation: a propensity score matching study.

BACKGROUND: A shortage of kidney grafts has led to the implementation of various strategies, including donations after circulatory death. The in situ normothermic regional perfusion technique has been introduced to improve graft quality by reducing warm ischemia times. However, there is limited evidence available on its mid- and long-term outcomes. Therefore, this study aimed to compare the incidence of delayed graft function, graft function, and survival at three years among three groups: brain death donors, rapid recovery, and normothermic regional perfusion. METHODS: A retrospective analysis of a cohort of kidney transplantations was conducted at a single referral center between January 1, 2015, and December 31, 2019. Univariate and multivariate regression models and propensity score matching analysis were performed to compare recipient-related, transplantation procedure-related, donor-related, and kidney function variables. RESULTS: A total of 327 patients were included, with 256 kidneys from brain death donors, 52 kidneys from rapid recovery, and 19 patients from normothermic regional perfusion. After propensity score matching, univariate and multivariate analyses showed a higher incidence of delayed graft function in the rapid recovery group compared to the others (OR: 2.39 CI95%: 1.19, 4.77) with a longer hospital stay (median 11, 15 and 10 days, respectively). However, no differences in 1- and 3-year graft function and survival were found. CONCLUSIONS: Normothermic regional perfusion offers advantages over rapid recovery, with a reduced incidence of delayed graft function and a shorter hospital stay. However, no differences in mid-term graft function and survival were found.

Kidney Survival Impact of Delayed Graft Function Depends on Kidney Donor Risk Index: A Single-Center Cohort Study.

BACKGROUND: Delayed graft function (DGF) is a significant challenge in renal transplantation, particularly with deceased donors, necessitating early postoperative dialysis. The prolonged effects of medium- and long-term DGF remain uncertain, marked by contradictory graft survival outcomes. This incongruity might arise from the inherent graft resilience and regenerative capacity during transplantation. This study investigates DGF's impact on graft survival, focusing on grafts displaying favorable (KDRI < 1) and unfavorable outcomes (KDRI ≥ 1). METHODS: In this retrospective cohort study (January 2015-December 2019), we assessed kidney transplants at our center, excluding multiorgan simultaneous cases, primary non-functioning grafts, and surgical complications causing graft loss. Patients were categorized into DGF presence or absence groups. Univariate and multivariate analyses, alongside propensity score matching (PSM), were performed. RESULTS: The study encompassed 322 deceased donor kidneys, with 83 encountering DGF. Grafts with higher KDRI indices (KDRI ≥ 1) and DGF exhibited a notably increased graft loss risk (HR: 4.17, 95% CI: 1.93-9.01). However, lower-KDRI donor grafts displayed no significant disparities between the DGF and non-DGF groups. CONCLUSIONS: Delayed graft function (DGF) development significantly contributes to graft loss in kidney transplants, particularly in grafts with KDRI ≥ 1.

Motor Imagery and Pain Processing in Patients With Entrapment Neuropathies: A Cross-sectional Study.

OBJECTIVES: (1) To assess the ability to generate both kinesthetic and visual motor imagery in participants with carpal tunnel syndrome (CTS), compared with asymptomatic participants. (2) To assess the influence of psychophysiological and functional variables in the motor imagery process. METHODS: Twenty patients with unilateral CTS and 18 pain-free individuals were recruited. An observational case-control study with a nonprobability sample was conducted to assess visual and kinesthetic movement imagery ability and psychophysiological variables in patients with CTS compared with asymptomatic participants in a control group. The trial was conducted in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology statement. RESULTS: CTS patients have more difficulties in generating visual motor images compared with asymptomatic individuals ( t =-2.099; P <0.05; d=0.70). They need more time to complete the mental tasks (visual t =-2.424; P <0.05 and kinesthetic t =-2.200; P <0.05). A negative correlation was found between the ability to imagine and functional deficits ( r =-0.569; P =0.021) for the kinesthetic subscale and temporal summation ( r =-0.515; P <0.5). A positive correlation was found between pain pressure threshold homolateral (homolateral) and time to generate the visual mental images ( r =0.537; P <0.05). DISCUSSION: CTS patients have greater difficulty generating motor images than asymptomatic individuals. Patients also spend more time during mental tasks. CTS patients present a relationship between temporal summation and the capacity to generate kinesthetic images. In addition, the CST patients presented a correlation between chronometry mental tasking and mechanical hyperalgesia.

Midterm Outcomes of Kidney Transplantation from Expanded Criteria Donors After Circulatory Death: A Single-Center Retrospective Cohort Study.

OBJECTIVES: Kidney transplant is the optimal treatment for end-stage renal disease; however, due to the imbalance between demand and supply, several strategies have been implemented to increase the donor pool. To increase the number of donors, expanded criteria donors after circulatory death have been explored as an acceptable graft source. In this study, we compared graft survival, estimated glomerular filtration rate at 3 and 5 years, and the incidence of delayed graft function between standard and expanded criteria donors after brain death and between standard and expanded criteria donors after circulatory death. MATERIALS AND METHODS: A prospective cohort study was conducted between January 1, 2015, and December 31, 2019, at Reina Sofia University Hospital. Variables related to the donor, recipient, and transplant procedure were analyzed, and univariate and multivariate logistic and Cox regression analyses were performed. RESULTS: Our study included 308 deceased donor kidneys. The kidneys from standard criteria brain dead donors had higher estimated glomerular filtration rate than the other groups (P < .03).However, no significant differences in estimated glomerular filtration rate were observed among the suboptimal groups (expanded criteria and standard criteria donors after brain death and expanded criteria donors after circulatory death). The incidence of delayed graft function was significantly higher in expanded criteria donors after circulatory death than in the other groups (odds ratio = 6.9; 95% CI, 2.22-21.71; P < .001). Nevertheless, we found no significant differences in death-censored graft loss among the groups. CONCLUSIONS: Kidney transplants from expanded criteria donors and donors after cardiac death are comparable, even when both criteria are combined. The use of expanded criteria donor kidneys after cardiac death is therefore a suitable approach to expand the donor pool, despite the higher risk of delayed graft function, as there were no significant differences in death-censored graft loss.

Alergia por henna: tatuajes que dejan huella / Henna allergy: tattoos that make their mark

La mezcla de la henna natural con parafenilendiamina (PPD), un colorante sintético potenciador del color y la duración de los tatuajes, puede producir una reacción infrecuente de hipersensibilidad tipo IV. Presentamos el caso clínico de una mujer que presentó una reacción cutánea intensa un mes después de hacerse un tatuaje con henna negra. Dicha reacción se manifestó con maculopápulas sobreelevadas que reproducen el dibujo del tatuaje.(AU)

Tratamiento hospitalario de la bronquiolitis moderada-grave: ¿suero salino hipertónico o fisiológico? Análisis de factores de riesgo asociados al reingreso / Hospital treatment of moderate-severe bronchiolitis, hypertonic or physiological saline? Analysis of risk factors associated with readmission

Introducción: a pesar de los numerosos estudios publicados hasta la fecha sobre el tratamiento hospitalario de la bronquiolitis y de la prometedora eficacia del suero salino hipertónico, lo cierto es que existe controversia al respecto. Material y métodos: estudio observacional prospectivo que evalúa la eficacia del suero salino hipertónico al 3% frente al suero fisiológico en el tratamiento hospitalario de la bronquiolitis, en términos de reducción de estancia y de puntuación de escala clínica de gravedad; en una segunda fase se analizan factores de riesgo asociados al reingreso por broncoespasmo de los mismos pacientes. Resultados: se analizan 67 de los 73 pacientes ingresados por bronquiolitis, de los cuales 9 recibieron fisiológico y 58 hipertónico, con o sin broncodilatador asociado. La estancia hospitalaria fue de 6,07 ± 3,12 días para el grupo fisiológico, y de 6,67 ± 4,36 días para el grupo con hipertónico. La media de la puntuación (Wood-Downes modificado por Ferrés) para el grupo con fisiológico fue de 3,67 ± 1,1 y de 3,16 ± 1,1 para los que recibieron hipertónico. Para la segunda fase se obtiene una tasa de reingresos del 8,2%. Conclusiones: no encontramos diferencias significativas entre ambos grupos en tiempo de hospitalización ni en mejoría de escala clínica y días de oxigenoterapia. Pese al reducido tamaño muestral no observamos ninguna tendencia a favor de diferencias significativas en nuestra muestra. Los factores más relacionados con el reingreso han sido la edad menor a 6 meses, el sexo masculino, el tener hermanos mayores y el tabaquismo familiar

Introduction: although numerous studies have been published to date on the subject of inpatient management of bronchiolitis and the promising outcomes obtained with hypertonic saline, this subject remains controversial. Materials and methods: we conducted a prospective observational study to assess the effectiveness of 3% hypertonic saline compared to physiological saline in the inpatient management of bronchiolitis, understood as the achieved reductions in length of stay and clinical severity scores. In a second phase, we analysed the risk factors associated with readmission due to bronchospasm in the same sample of patients. Results: we included 67 out of the 73 patients admitted with bronchiolitis in the analysis, of who 9 received physiological saline and 58 hypertonic saline, with or without an added bronchodilator. The mean length of stay was 6.07 ± 3.12 days in the physiological saline group and 6.67 ± 4.36 days in the hypertonic saline group. The mean severity score (Wood-Downes scale modified by Ferrés) was 3.67 ± 1.1 in the physiological saline group versus 3.16 ± 1.1 in the hypertonic saline group. In the second phase of the study, we found a readmission rate of 8.2%. Conclusion: we did not find statistically significant differences between the two groups in the length of stay or in the improvement in the clinical severity score or duration of oxygen therapy. Although the sample size was small, we did not find any trends in our sample suggesting the actual presence of significant differences. The factors associated most strongly with readmission were age of less than 6 months, male sex, having older siblings and exposure to smoke in the household

Quantitative profile of lipid classes in blood by normal phase chromatography with evaporative light scattering detector: application in the detection of lipid class abnormalities in liver cirrhosis.

BACKGROUND: The lack of analytical methods specific for each lipid class, particularly for phospholipids and sphyngolipids, makes necessary their separation by preparative techniques before quantification. LC-MS would be the election method but for daily work in the clinical laboratory this is not feasible for different reasons, both economic and time consuming. In the present work, we have optimized an HPLC method to quantify lipid classes in plasma and erythrocytes and applied it to samples from patients with cirrhosis. METHODS: Lipid classes were analyzed by normal phase liquid chromatography with evaporative light scattering detection. We employed a quaternary solvent system to separate twelve lipid classes in 15 min. RESULTS: Interday, intraday and recovery for quantification of lipid classes in plasma were excellent with our methodology. The total plasma lipid content of cirrhotic patients vs control subjects was decreased with diminished CE (81±33 vs 160±17 mg/dL) and PC (37±16 vs 60±19 mg/dL). The composition of erythrocytes showed a decrease in acidic phospholipids: PE, PI and PS. CONCLUSION: Present methodology provides a reliable quantification of lipid classes in blood. The lipid profile of cirrhotics showed alterations in the PC/PE plasma ratio and in the phospholipid content of erythrocytes, which might reflect alterations in hepatocyte and erythrocyte membrane integrity.
