AI Article Synopsis

  • The study aimed to find out how common Acute Kidney Injury (AKI) is among COVID-19 patients and what factors contribute to it.
  • 176 patients were analyzed, with a 51.1% prevalence rate of AKI, predominantly affecting older males.
  • Key risk factors included older age, long hospital stays, and various health complications like diabetes and hypoxemia.

Article Abstract

Objective: To determine the frequency of Acute Kidney Injury (AKI) and its underlying risk factors in patients with Coronavirus Disease (COVID-19).

Methods: This retrospective study was conducted by reviewing the medical records of patients admitted in Covid-19 Intensive Care Unit (ICU) of Farooq Hospital, West Wood Branch, Lahore during the period from 1 April, 2020 to 30 June, 2020. COVID-19 was diagnosed on basis of Real Time Polymerase Chain Reaction (RT-PCR) through nasal swab. Demographic, clinical and laboratory data were collected at the time of admission in the hospital. AKI was diagnosed on basis of ≥ 0.3 mg/dl increase in serum Creatinine (sCr) from baseline during the hospital stay. The outcome of study was AKI.

Results: One hundred and seventy-six patients who fulfilled the inclusion criteria were recruited of which most were males (78.4%). The mean age was 51.26 ± 15.20 years and the frequency of AKI was 51.1%. The risk factors for AKI were increasing age (OR=2.10, =0.017); presence of COVID-19 symptoms (OR=6.62, =0.004); prolonged hospital stay (OR=2.26, =0.011); Diabetes Mellitus (OR=1.81, =0.057); hypoxemia (OR=5.98, =0.000); leukocytosis (OR=2.91, =0.002); lymphopenia (OR=5.77, =0.000); hypoalbuminemia (OR=4.94, =0.000); elevated C-reactive protein (CRP) (OR=6.20, =0.000) and raised D-diamers (OR=3.16, =0.000).

Conclusions: AKI was present in half of the COVID-19 patients. The most significant risk factors for AKI were increasing age, prolonged hospital stay, hypoxemia, hypoalbuminemia, DM and raised inflammatory markers.

In this study, we first analyzed data from 147 patients with solitary plasmacytomas treated at the Mayo Clinic between 2005 and 2022 and then expanded our investigation through a systematic review and meta-analysis of 62 studies, encompassing 3,487 patients from the years 1960 to 2022. Our findings reveal that patients with up to 10% clonal plasma cells in their bone marrow (BM), denoted as plasmacytoma +, had a significantly reduced median disease-free survival (DFS) of 15.7 months vs.

Background: Gastrointestinal bleeding (GIB) is a severe and potentially life-threatening complication in patients with acute myocardial infarction (AMI), significantly affecting prognosis during hospitalization. Early identification of high-risk patients is essential to reduce complications, improve outcomes, and guide clinical decision-making.

Objective: This study aimed to develop and validate a machine learning (ML)-based model for predicting in-hospital GIB in patients with AMI, identify key risk factors, and evaluate the clinical applicability of the model for risk stratification and decision support.

Background: Health worker migration from Nigeria poses significant challenges to the Nigerian health care sector and has far-reaching implications for health care systems globally. Understanding the factors driving migration, its effects on health care delivery, and potential policy interventions is critical for addressing this complex issue.

Objective: This study aims to comprehensively examine the factors encouraging the emigration of Nigerian health workers, map out the effects of health worker migration on the Nigerian health system, document the loss of investment in health training and education resulting from migration, identify relevant policy initiatives addressing migration, determine the effects of Nigerian health worker migration on destination countries, and identify the benefits and demerits to Nigeria of health worker migration.

Background: The utility of aging metrics that incorporate cognitive and physical function is not fully understood.

Objective: We aim to compare the predictive capacities of 3 distinct aging metrics-motoric cognitive risk syndrome (MCR), physio-cognitive decline syndrome (PCDS), and cognitive frailty (CF)-for incident dementia and all-cause mortality among community-dwelling older adults.

Methods: We used longitudinal data from waves 10-15 of the Health and Retirement Study.
