The use of regional citrate anticoagulation (RCA) in liver failure (LF) patients can lead to citrate accumulation. We aimed to evaluate serum levels of citrate and correlate them with liver function markers and with the Cat/Cai in patients under intensive care and undergoing continuous venovenous hemodiafiltration with regional citrate anticoagulation (CVVHDF-RCA). A prospective cohort study in an intensive care unit was conducted. We compared survival, clinical, laboratorial and dialysis data between patients with and without LF. Citrate was measured daily. We evaluated 200 patients, 62 (31%) with LF. Citrate was significantly higher in the LF group. Dialysis dose, filter lifespan, systemic ionized calcium and Cat/Cai were similar between groups. There were weak to moderate positive correlations between Citrate and indicators of liver function and Cat/Cai. The LF group had higher mortality (70.5% vs. 51.8%, p = 0.014). Citrate was an independent risk factor for death, OR 11.3 (95% CI 2.74-46.8). In conclusion, hypercitratemia was an independent risk factor for death in individuals undergoing CVVHDF-ARC. The increase in citrate was limited in the LF group, without clinical significance. The correlation between citrate and liver function indicators was weak to moderate., (© 2023. The Author(s).)

Background: Acute kidney injury is a common complication in solid organ transplants, notably liver transplantation. The MELD is a score validated to predict mortality of cirrhotic patients, which is also used for organ allocation, however the influence of this allocation criteria on AKI incidence and mortality after liver transplantation is still uncertain., Methods: This is a retrospective single center study of a cohort of patients submitted to liver transplant in a tertiary Brazilian hospital: Jan/2002 to Dec/2013, divided in two groups, before and after MELD implementation (pre-MELD and post MELD). We evaluate the differences in AKI based on KDIGO stages and mortality rates between the two groups., Results: Eight hundred seventy-four patients were included, 408 in pre-MELD and 466 in the post MELD era. The proportion of patients that developed AKI was lower in the post MELD era (p 0.04), although renal replacement therapy requirement was more frequent in this group (p < 0.01). Overall mortality rate at 28, 90 and 365 days was respectively 7%, 11% and 15%. The 1-year mortality rate was lower in the post MELD era (20% vs. 11%, p < 0.01). AKI incidence was 50% lower in the post MELD era even when adjusted for clinically relevant covariates (p < 0.01)., Conclusion: Liver transplants performed in the post MELD era had a lower incidence of AKI, although there were more cases requiring dialysis. 1-year mortality was lower in the post MELD era, suggesting that patient care was improved during this period., (© 2022.

Background: Hospitals are constantly searching for opportunities to improve efficiency, and telehealth (TH) has recently emerged as a strategy to assist in patient flow. We evaluated two methods of dietary counseling offered to patients in the time period between the medical and final hospital discharge. Counseling was given either via the TH group or the face to face (FTF) group to the patients and their respective impact was evaluated on the patients' satisfaction and on the hospital patient flow., Methods: This study was a prospective, randomized clinical trial where patients were randomized to receive dietary counseling via TH (use of tablet) or FTF at the time of hospital discharge. We evaluate the duration of time between medical discharge and hospital discharge; between requesting dietary counseling and dietitian's arrival; and duration of dietary counseling. At the end of dietary counseling, both groups received a patient satisfaction questionnaire to answer., Results: A total of 159 patients were randomized to receive dietary counseling via TH (TH, n  = 78) or FTF (FTF, n  = 81). The two groups TH and FTF did not differ in terms of the median time between (1) medical and hospital discharge; (2) requesting counseling and the dietitian's arrival; and (3) duration of dietary counseling. Both groups mostly reported being "satisfied" or "above expectations," and the FTF group scored "highest satisfaction" more often relative to the dietitian's work and interaction and on confidence in the dietitian's orientations. Finally, in the TH group, 90.7% graded likely-4 or very likely-5 when asked whether dietary counseling can be conducted entirely via TH, and 92% answered "4" or "5" when asked whether they would recommend dietary counseling via TH., Conclusions: Although the FTF group had a greater overall satisfaction relative to the TH group, TH proved to be a useful tool for dietary counseling.The trial has only Institutional Review Board approval (protocol 2685-16)., Competing Interests: No competing financial interests exist., (© Mayumi Shima et al., 2022; Published by Mary Ann Liebert, Inc.)
