The impact of posttraumatic stress disorder and head injury on reactive and appetitive aggression in adult Syrian refugees in Lebanon.

Objective: Refugees are highly vulnerable to mental health disorders and head injuries. The primary aim of this study is to examine the impact of posttraumatic stress disorder (PTSD) and head injury on reactive and appetitive aggression in adult Syrian refugees in Lebanon.

Method: A cross-sectional study was conducted targeting adult Arab United Nations High Commissioner for Refugees-registered Syrian refugees residing in Beirut and southern regions of Lebanon.

Survey of CT radiation doses and iodinated contrast medium administration: an international multicentric study.

Objective: To assess the relationship between intravenous iodinated contrast media (ICM) administration usage and radiation doses for contrast-enhanced (CE) CT of head, chest, and abdomen-pelvis (AP) in international, multicenter settings.

Methods: Our international (n = 16 countries), multicenter (n = 43 sites), and cross-sectional (ConRad) study had two parts. Part 1: Redcap survey with questions on information related to CT and ICM manufacturer/brand and respective protocols.

Early Detection of Heart Failure with Autonomous AI-Based Model Using Chest Radiographs: A Multicenter Study.

The opportunistic use of radiological examinations for disease detection can potentially enable timely management. We assessed if an index created by an AI software to quantify chest radiography (CXR) findings associated with heart failure (HF) could distinguish between patients who would develop HF or not within a year of the examination. Our multicenter retrospective study included patients who underwent CXR without an HF diagnosis.

Multicenter, international study of CT practices and radiation doses from 10 African countries: An International Atomic Energy Agency (IAEA) baseline study.

Purpose: The objective of our IAEA-coordinated international study was to assess CT practices and radiation doses from multiple hospitals across several African countries.

Methods: The study included 13 hospitals from Africa which contributed information on minimum of 20 consecutive patients who underwent head, chest, and/or abdomen-pelvis CT. Prior to the data recording step, all hospitals had a mandatory one-hour training on the best practices in recording the relevant data elements.
