Introduction: This study investigated outcomes in critically unwell acute kidney injury patients and the role of the National Early Warning Score and other factors in identifying patients who experience negative outcomes.
Methods: Retrospective cohort study investigating 64 patients seen by Critical Care Outreach between November 2014 and February 2015. Mortality at one year was analysed using multivariate regression; all other statistical tests were non-parametric.
Results: Forty-four per cent of patients required escalation to higher level care, 56% failed to survive beyond one year and 30% of those who did survive had a deterioration in renal function. Previous acute kidney injury significantly predicted mortality but the National Early Warning Score did not. A subgroup of patients developed Stage 3 acute kidney injury before a rise in National Early Warning Score.
Conclusions: Acute kidney injury in the Critical Care Outreach patient population is associated with high morbidity and mortality. Previous acute kidney injury and acute kidney injury stage may be superior to the National Early Warning Score at identifying patients in need of Critical Care Outreach review.

The management of anticoagulation and antiplatelet therapy in stage V chronic kidney disease (CKD) patients undergoing renal transplantation remains controversial. Some centers advocate for the use of reversal agents or procoagulants preoperatively, while others suggest that transplantation can proceed safely without halting these treatments. This study aims to evaluate the incidence of hemorrhagic and thrombotic complications in the first 72 hours post-transplant in patients receiving anticoagulant or antiplatelet therapy compared to a control group without such treatments.

Targeting optimal glycemic control based on hemoglobin A1c (A1c) values reduces but does not abolish the onset of diabetic kidney disease and its progression to chronic kidney disease (CKD). This suggests that factors other than the average glucose contribute to the residual risk. Vitamin D deficiency and frequent episodes of acute hyperglycemia (AH) are associated with the onset of albuminuria and CKD progression in diabetes.

Introduction: Folate receptors (FR) have been considered a convenient target for different radiopharmaceuticals in recent years. Multifarious Ga-labeled folate conjugates have been proposed as promising agents for the PET imaging of FR-overexpressing malignant neoplasms. In addition, radiolabeled folate-based conjugates can be effective for imaging non-tumor pathological foci characterized by a pronounced cluster of activated macrophages.

Patients with acute kidney injury often require dialysis (AKI-D) in the outpatient setting following hospitalization. Management of the patient with AKI-D should focus on preventing further insult to the damaged kidney and recovery of kidney function. Clinical attention should include continuity of care, education, infection control, medication management, and fluid management.
