AI Article Synopsis
- Acute kidney injury (AKI) is a common issue among critically ill COVID-19 patients in ICUs, with rates ranging between 25% to 89%, making its exact incidence unclear in Norway.
- The study analyzed data from 361 COVID-19 patients in Norwegian ICUs, finding that 32% had AKI upon admission, and factors like age and acute circulatory failure increased the risk.
- Survival rates were 82.5% at 30 days and 77.6% at 90 days after hospital admission, with cancer being a predictor for 30-day mortality, along with other factors related to AKI and circulatory failure.
Article Abstract
Objectives: Acute kidney injury (AKI) is a frequent complication among critical ill patients with COVID-19, but the actual incidence is unknown as AKI-incidence varies from 25% to 89% in intensive care unit (ICU) populations. We aimed to describe the prevalence and risk factors of AKI in patients with COVID-19 admitted to ICU in Norway.
Design: Nation-wide observational study with data sampled from the Norwegian Intensive Care and Pandemic Registry (NIPaR) for the period between 10 March until 31 December 2020.
Setting: ICU patients with COVID-19 in Norway. NIPaR collects data on intensive care stays covering more than 90% of Norwegian ICU and 98% of ICU stays.
Participants: Adult patients with COVID-19 admitted to Norwegian ICU were included in the study. Patients with chronic kidney disease (CKD) were excluded in order to avoid bias from CKD on the incidence of AKI.
Primary And Secondary Outcome Measures: Primary outcome was AKI at ICU admission as defined by renal Simplified Acute Physiology Score in NIPaR. Secondary outcome measures included survival at 30 and 90 days after admission to hospital.
Results: A total number of 361 patients with COVID-19 were included in the analysis. AKI was present in 32.0% of the patients at ICU admission. The risk for AKI at ICU admission was related to acute circulatory failure at admission to hospital. Survival for the study population at 30 and 90 days was 82.5% and 77.6%, respectively. Cancer was a predictor of 30-day mortality. Age, acute circulatory failure at hospital admission and AKI at ICU admission were predictors of both 30-day and 90-day mortality.
Conclusions: A high number of patients with COVID-19 had AKI at ICU admission. The study indicates that AKI at ICU admission was related to acute circulatory failure at hospital admission. Age, acute circulatory failure at hospital admission and AKI at ICU admission were associated with mortality.

Purpose: To analyze the latest annual trends in immediate sequential bilateral cataract surgery (ISBCS) and delayed sequential bilateral cataract surgery (DSBCS) among patients with bilateral cataracts in Korea, and to identify the factors influencing the choice of surgery and the outcomes associated with ISBCS and DSBCS.
Methods: This retrospective, nationwide cohort study included all patients aged 65 and older who were covered by the Korean National Health Insurance and underwent ISBCS or DSBCS from 2016 to 2021. The study recorded yearly numbers of ISBCS and DSBCS procedures, the interval between surgeries in DSBCS cases, patient demographics, types of implanted intraocular lenses (IOLs), and the incidence of cystoid macular edema and endophthalmitis following ISBCS or DSBCS.

<b>Introduction:</b> Central venous thrombosis (CVT) represents a well-documented complication of acute otitis media (AOM) and acute mastoiditis (AM). Despite widespread antibiotic utilization, which has significantly reduced the incidence of severe AOM/AM complications, recent years have witnessed an increasing frequency of thrombotic complications in pediatric patients, not invariably presenting with classical neurological manifestations.<b>Aim:</b> This study aimed to investigate the potential correlation between COVID-19 infection and increased CVT incidence, while sharing therapeutic experiences, given the absence of standardized treatment protocols for otogenic CVT in pediatric populations.
