Purpose: Frailty is the body’s failure to return to homeostasis after every day or acute stressful events, causing adverse outcomes. To study its dynamics in kidney transplant recipients (KTR), we determined whether the degree of frailty and its domains are affected by kidney transplantation (KT). Methods: Between 2015 and 2017, 176 KTR were included. Frailty scores were measured using the Groningen Frailty Indicator (GFI), assessed preoperatively and during follow-up. Transitions in frailty state and changes in the individual domains were determined. Results: Mean age (±SD) was 51.8 (± 14.1) years, and 63.1% of KTR were male. Thirty patients were considered frail (GFI ≥ 4) at baseline. After a mean follow-up of 22.8 ± 8.3 months, 34 non-frail patients (19.3%) became frail, 125 patients (71.0%) remained the same, and 17 frail patients (9.7%) became non-frail (GFI < 4). In the domain psychosocial functioning, 28.4% of the patients had an increase in GFI score after follow-up. Patients who scored a point in the domain cognition at baseline had a greater chance of becoming frail (OR 4.38, 95% CI 0.59–32.24). Conclusion: In conclusion, almost one-fifth of non-frail KTR transitioned to a frail state after their transplantation. These results could be used to predict the impact of KT on frailty course and help with implementing prehabilitation for patients at risk.

Purpose: This study sets out to analyze the correlation of ET-1, a vasoactive peptide, along with various cytokines and vascular factors, with clinical parameters and OCT/OCT-A measurements in glaucoma participants. Methods: Eyes of participants with cataract (n = 30) or glaucoma (n = 87) were examined with optical coherence tomography (OCT) and OCT angiography (OCT-A). Aqueous humor (AqH) from the examined eye and plasma were sampled during cataract or glaucoma surgery and analyzed by means of ELISA and Luminex assay to determine their levels of ET-1 and 35 proteins deemed relevant for regulation of the AqH outflow pathway, ocular perfusion (OP), and glucose metabolism. Results: Glaucomatous eyes are characterized by reductions in RNFL thickness and OP, reflected by reduced vessel density. Furthermore, significantly elevated peripheral ET-1 levels were detected in participants with glaucoma. In addition, significantly elevated AqH levels of MMP-2, MMP-3, ET-1, sEMMPRIN, ZAG, sLOX-1, follistatin, cortisol, endostatin, sTIE-2, and PDGF-BB were detected in the glaucomatous eyes, with correlation to reduced VD for APN, C3a, MMP-3, resistin, sTIE-2, and ZAG. Multivariable analysis showed a correlation of AqH APN levels with the reduced VD in glaucomatous eyes. Conclusions: The peripheral ET-1 level and the intraocular levels of APN, C3a, MMP-3, resistin, sTIE-2, and ZAG are associated with impaired OP in glaucoma. Furthermore, elevated intraocular levels of MMP-3, ZAG, and APN were identified as biomarkers for impaired perfusion in glaucoma.

A male in his 20s with no medical history was found with generalised seizures and profound hypoglycaemia after consuming improperly stored, reheated rice. Initial laboratory tests showed acute liver failure with hyperammonaemia, acute kidney injury and lactic acidosis, which rapidly progressed to multi-organ failure requiring urgent liver transplantation evaluation. With maximal supportive therapy, including glucose, ammonia and glutamine scavengers, renal replacement therapy, haemodynamic and respiratory support, he gradually improved, avoiding transplantation and achieving full neurological recovery. Toxicological analysis of the rice and serum revealed high concentrations of cereulide, a toxin produced by Bacillus cereus . This case illustrates that cereulide intoxication can be associated with potentially fatal multi-organ failure, particularly after ingestion of improperly stored starchy foods. Early recognition through targeted dietary history, focused laboratory evaluation and prompt supportive therapy are essential. Increasing awareness among healthcare professionals and safe food storage practices are key preventive measures.
