Risk factors and comorbidities associated with cardiac arrests and medical emergencies in interventional radiology patients.

Purpose: To investigate the incidence, predictors, and outcomes of medical emergencies in patients undergoing IR procedures at a tertiary care center.

Materials And Methods: Seven-year retrospective review of all medical emergencies in patients undergoing IR procedures at King Abdulaziz Medical City, Riyadh, Saudi Arabia. Medical emergencies included Cardiopulmonary arrest (CPA), or emergencies that required activation of the critical care response team (CCRT).

Assessment of Women's Discretionary Salt Intake and Household Salt Utilization in Preparation for a Salt Fortification Trial in Oromia Region, Ethiopia.

There is a high incidence of neural tube defects (NTDs) in Ethiopia and folate insufficiency, a primary risk factor for NTDs, is common among Ethiopian women of reproductive age (WRA). Folic acid fortification of salt has been proposed as a strategy to control these problems. In preparation for an intervention trial to assess the nutritional effects of folic acid-fortified salt, we measured discretionary salt intakes among nonpregnant WRA using observed weighed food records, and we assessed household salt disappearance rates.

Adverse effects of COVID-19 vaccine in the paediatric population: a focus on the cardiovascular system.

The COVID-19 pandemic had an unprecedented impact on healthcare systems and exists globally. To control pandemic progression, COVID-19 vaccines were developed and licensed for use in the adult population in early 2021 and became available in paediatric cohorts several months later. Since then, several studies have reported adverse events and severe adverse events in the adult and paediatric cohorts.

A Lagrangian relaxation approach for algae-based biofuel supply chain network design under uncertainty and pricing issue.

Biofuel has gained significant attention as a potential source to meet fuel demands instead of fossil fuel. The price of biofuel and alternative fuel have a considerable impact on biofuel demand. Thus, it is important to design a biofuel supply chain network that incorporates the biofuel price into an elastic demand.
