AI Article Synopsis

  • The study investigates the incidence of acute kidney injury (AKI) in patients hospitalized with COVID-19, aiming to inform healthcare plans.
  • The research analyzed data from 30 studies, involving over 18,000 adult COVID-19 patients, finding an overall AKI incidence of 9.2%, and particularly high rates (32.6%) in intensive care units.
  • The findings highlight that AKI is common in COVID-19 patients, especially among the elderly and those with severe respiratory illness, with a significant mortality rate of 50.4% among those with AKI.

Article Abstract

Background And Aim: The knowledge about the acute kidney injury (AKI) incidence in patients with coronavirus disease 2019 (COVID-19) can help health teams to carry out a targeted care plan. This study aimed to determine the AKI incidence in patients hospitalized with COVID-19.

Methods: The electronic search covered research published until June 20, 2020, and included five databases, PubMed, Embase, Web of Science, Scopus, and Lilacs (Latin American and Caribbean Health Sciences Library). Eligible studies were those including data from AKI occurrence in adult patients hospitalized with COVID-19. The primary outcome was AKI incidence, and the secondary outcome assessed was the AKI mortality. Additionally, the estimated incidence of renal replacement therapy (RRT) need also was verified. Using a standardized form prepared in Microsoft Excel, data were extracted by two independents authors, regarding the description of studies, characteristics of patients and clinical data on the AKI occurrence.

Results: We included 30 studies in this systematic review, of which 28 were included in the meta-analysis. Data were assessed from 18.043 adult patients with COVID-19. The AKI estimate incidence overall and at the ICU was 9.2% (4.6-13.9) and 32.6% (8.5-56.6), respectively. AKI estimate incidence in the elderly patients and those with acute respiratory disease syndrome was 22.9% (-4.0-49.7) and 4.3% (1.8-6.8), respectively. Patients with secondary infection, AKI estimate incidence was 31.6% (12.3-51.0). The estimate incidence of patients that required RRT was 3.2% (1.1-5.4) and estimate AKI mortality was 50.4% (17.0-83.9).

Conclusion: The occurrence of AKI is frequent among adult patients hospitalized with COVID-19, and affects on average, up to 13.9% of these patients. It is believed that AKI occurs early and in parallel with lung injury.

Introduction: Young adults with inflammatory bowel disease (IBD) are at the risk of poor outcomes when transferring to adult providers. We aimed to increase the percentage of patients with 14-17 years of age undergoing the transition of care and the percentage of patients 18-21 years of age initiating the transfer of care to 50% for 12 months. Our goal was also to improve patient satisfaction with the transfer process.

Risk Factors for Infection-Attributable Mortality in Patients With Bacteremia: A Competing Risk Analysis.

Open Forum Infect Dis

January 2025

Division of Infectious Diseases, Department of Internal Medicine, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Republic of Korea.

Background: Identifying risk factors for mortality in patients with bacteremia (SAB) is crucial due to its high fatality. However, data on risk factors for infection-attributable deaths considering competing risk events such as non-infection-attributable deaths remain limited. We performed a competing risk analysis to elucidate risk factors associated with 30-day infection-attributable mortality in a large cohort of patients with SAB.

The aging population presents critical challenges to global healthcare systems, with Japan expected to have 35% of its population aged 65 or older by 2040. Older adults often experience multimorbidity, cognitive impairments, and physical frailties, increasing healthcare utilization and costs. Traditional medical approaches that focus on organ-specific diagnoses are insufficient for addressing these multifaceted needs.

Background: Deprescribing is a critical component of clinical practice, especially in geriatric medicine. Nevertheless, the attributes of patients who are prepared for, interested in, and could potentially benefit from deprescribing have not been well examined. The Patient Perceptions of Deprescribing (PPoD) evaluates patients' overall readiness for deprescribing and is complemented by an 11-item validated short form (SF-PPoD).
