Derivation and external validation of a simple risk score for predicting severe acute kidney injury after intravenous cisplatin: cohort study.

Objective: To develop and externally validate a prediction model for severe cisplatin associated acute kidney injury (CP-AKI).

Design: Multicenter cohort study.

Setting: Six geographically diverse major academic cancer centers across the US.

Fructose: A New Variable to Consider in SIADH and the Hyponatremia Associated With Long-Distance Running?

Fructose has recently been proposed to stimulate vasopressin secretion in humans. Fructose-induced vasopressin secretion is not only postulated to result from ingestion of fructose-containing drinks but may also occur from endogenous fructose production via activation of the polyol pathway. This raises the question of whether fructose might be involved in some cases of vasopressin-induced hyponatremia, especially in situations where the cause is not fully known such as in the syndrome of inappropriate secretion of diuretic hormone (SIADH) and exercise-associated hyponatremia, which has been observed in marathon runners.

Machine Learning Prediction of Death in Critically Ill Patients With Coronavirus Disease 2019.

Objectives: Critically ill patients with coronavirus disease 2019 have variable mortality. Risk scores could improve care and be used for prognostic enrichment in trials. We aimed to compare machine learning algorithms and develop a simple tool for predicting 28-day mortality in ICU patients with coronavirus disease 2019.

Extracorporeal membrane oxygenation in patients with severe respiratory failure from COVID-19.

Purpose: Limited data are available on venovenous extracorporeal membrane oxygenation (ECMO) in patients with severe hypoxemic respiratory failure from coronavirus disease 2019 (COVID-19).

Methods: We examined the clinical features and outcomes of 190 patients treated with ECMO within 14 days of ICU admission, using data from a multicenter cohort study of 5122 critically ill adults with COVID-19 admitted to 68 hospitals across the United States. To estimate the effect of ECMO on mortality, we emulated a target trial of ECMO receipt versus no ECMO receipt within 7 days of ICU admission among mechanically ventilated patients with severe hypoxemia (PaO/FiO < 100).

Association Between Early Treatment With Tocilizumab and Mortality Among Critically Ill Patients With COVID-19.

Importance: Therapies that improve survival in critically ill patients with coronavirus disease 2019 (COVID-19) are needed. Tocilizumab, a monoclonal antibody against the interleukin 6 receptor, may counteract the inflammatory cytokine release syndrome in patients with severe COVID-19 illness.

Objective: To test whether tocilizumab decreases mortality in this population.

AKI Treated with Renal Replacement Therapy in Critically Ill Patients with COVID-19.

Background: AKI is a common sequela of coronavirus disease 2019 (COVID-19). However, few studies have focused on AKI treated with RRT (AKI-RRT).

Methods: We conducted a multicenter cohort study of 3099 critically ill adults with COVID-19 admitted to intensive care units (ICUs) at 67 hospitals across the United States.

In-hospital cardiac arrest in critically ill patients with covid-19: multicenter cohort study.

Objectives: To estimate the incidence, risk factors, and outcomes associated with in-hospital cardiac arrest and cardiopulmonary resuscitation in critically ill adults with coronavirus disease 2019 (covid-19).

Design: Multicenter cohort study.

Setting: Intensive care units at 68 geographically diverse hospitals across the United States.

Continuous Renal Replacement Therapy Dosing in Critically Ill Patients: A Quality Improvement Initiative.

Rationale & Objective: Clinical practice guidelines recommend delivering a continuous renal replacement therapy (CRRT) dose of 20 to 25mL/kg/h. However, practice patterns nationwide are highly variable; this inconsistent prescribing may lead to errors in medication dosing and increase rates of electrolyte and acid-base abnormalities. We describe an initiative to standardize CRRT practice patterns and reduce dosing variability.

Continuous Renal Replacement Therapy Dosing in the Severely Underweight: A Case Report.

Guidelines recommend that patients treated with continuous renal replacement therapy be delivered an effluent dose of 20 to 25 mL/kg/h. There is debate, especially at the extremes of body mass index, as to whether actual or ideal body weight (IBW) should be used in these dose calculations. A middle-aged woman with severe anorexia presented with 48 hours of altered mental status.

Extremely high ferritin level after an acute myocardial infarction in an end stage renal disease patient.

We present here a case of an asymptomatic end-stage renal disease (ESRD) patient, who had an unexplained persistent mild leukocytosis in the setting of an extremely high ferritin level (8,997 ng/ml; reference range: 12 - 300 ng/ml) 3 weeks after she suffered from a myocardial infarction (MI). Infection as the cause of these laboratory abnormalities was ruled out. A week later, the patient was noted to have asymptomatic hypotension (100/60 mmHg; her baseline blood pressure was 120/70 mmHg) during a maintenance hemodialysis session.

Effect of aggressively driven intravenous iron therapy on infectious complications in end-stage renal disease patients on maintenance hemodialysis.

For treating end-stage renal disease-associated anemia, various strategies to achieve optimal hemoglobin levels with lower erythropoiesis stimulating agent doses are being tried. One of these involves the use of a high dose [transferrin saturation (TSAT) >30%] of intravenous (IV) iron supplementation. However, due to in vitro effects of iron on stimulating bacterial growth, there are concerns of increased risk of infection.

C3 glomerulopathy masquerading as acute postinfectious glomerulonephritis.

We report the case of a 63-year-old man who presented with acute kidney injury, active urine sediment, nephrotic syndrome, and hypocomplementemia after a recent report of a sore throat. Kidney biopsy showed diffuse proliferative and exudative glomerulonephritis with C3-dominant staining by immunofluorescence. Taken together, clinical and pathologic findings were most suggestive of acute postinfectious glomerulonephritis, although the history of full nephrotic syndrome, presence of segmental membranoproliferative features, and absence of classic subepithelial hump-shaped deposits were unusual for this condition.

Pathophysiology and management of acute kidney injury in the setting of abdominal compartment syndrome.

Abdominal compartment syndrome (ACS) is defined as an organ dysfunction caused by intra-abdominal hypertension (IAH). Up to 4.2% of the patients in intensive care unit may develop IAH with it being an independent predictor of mortality.

Effect of lower calcium dialysate on laboratory abnormalities in chronic kidney disease-associated mineral and bone disorder.

Increased vascular calcification, possibly due to the biochemical problem of calcium (Ca) and phosphate excess, has been associated with cardiovascular disease in patients with end stage renal disease. The use of a lower dialysate Ca concentration (<2.50 mEq/L) has been postulated as one of the methods to prevent long-term Ca accumulation.
