AI Article Synopsis
- Military operations have different scopes and characteristics, impacting casualty care evaluation based on past fatalities.
- A study of US military deaths during Operation New Dawn (2010-2011) found that injuries were the leading cause of death, primarily due to homicide and non-suicidal trauma.
- Most fatalities involved conventional forces, with a significant number of combatants and support personnel suffering from severe injuries that were largely nonpreventable.
Article Abstract
Background: Military operations vary by scope, purpose, and intensity, each having unique forces and actions to execute a mission. Evaluation of military operation fatalities guides current and future casualty care.
Methods: A retrospective study was conducted of all US military fatalities from Operation New Dawn in Iraq, 2010 to 2011. Data were obtained from autopsies and other records. Population characteristics, manner of death, cause of death, and location of death were analyzed. All fatalities were evaluated for concomitant evidence of underlying atherosclerosis. Nonsuicide trauma fatalities were also reviewed for injury severity, mechanism of death, injury survivability, death preventability, and opportunities for improvement.
Results: Of 74 US military Operation New Dawn fatalities (median age, 26 years; male, 98.6%; conventional forces, 100%; prehospital, 82.4%) the leading cause of death was injury (86.5%). The manner of death was primarily homicide (55.4%), followed by suicide (17.6%), natural (13.5%), and accident (9.5%). Fatalities were divided near evenly between combatants (52.7%) and support personnel (47.3%), and between battle injury (51.4%) and disease and nonbattle injury (48.6%). Natural and suicide death was higher (p < 0.01, 0.02) among support personnel who were older (p = 0.05) with more reserve/national guard personnel (p = 0.01). Total population prevalence of underlying atherosclerosis was 18.9%, with more among support personnel (64.3%). Of 46 nonsuicide trauma fatalities, most died of blast injury (67.4%) followed by gunshot wound (26.1%) and multiple/blunt force injury (6.5%). The leading mechanism of death was catastrophic tissue destruction (82.6%). Most had nonsurvivable injuries (82.6%) and nonpreventable deaths (93.5%).
Conclusion: Operation New Dawn fatalities were exclusively conventional forces divided between combatants and support personnel, the former succumbing more to battle injury and the latter to disease and nonbattle injury including self-inflicted injury. For nonsuicide trauma fatalities, none died from a survivable injury, and 17.4% died from potentially survivable injuries. Opportunities for improvement included providing earlier blood products and surgery.
Level Of Evidence: Therapeutic, level V and epidemiological, level IV.

Hydrogen-Bonded Organic Framework Nanoscintillators for X-Ray-Induced Photodynamic Therapy in Hepatocellular Carcinoma.
Adv Mater

Department of Hepatobiliary Surgery, Eastern Hepatobiliary Surgery Hospital, Naval Medical University, Shanghai, 200438, P. R. China.
X-ray induced photodynamic therapy (X-PDT) leverages penetrating X-ray to generate singlet oxygen (O) for treating deep-seated tumors. However, conventional X-PDT typically relies on heavy metal inorganic scintillators and organic photosensitizers to produce O, which presents challenges related to toxicity and energy conversion efficiency. In this study, highly biocompatible organic phosphorescent nanoscintillators based on hydrogen-bonded organic frameworks (HOF) are designed and engineered, termed BPT-HOF@PEG, to enhance X-PDT in hepatocellular carcinoma (HCC) treatment.

Objectives: Opioid-associated fatal and non-fatal overdose rates continue to rise. Prehospital overdose education and naloxone distribution (OEND) programs are attractive harm-reduction strategies, as patients who are not transported by EMS after receiving naloxone have limited access to other interventions. This narrative summary describes our experiences with prehospital implementation of evidence-based OEND practices across Ohio as part of the HEALing Communities Study (HCS).

Article Synopsis
- Hilar cholangiocarcinoma (h-CCA) is a challenging cancer that starts in the bile duct's epithelial cells, often diagnosed at advanced stages, leading to high mortality rates.
- For patients who can't undergo surgery, systemic therapy and emerging immunotherapies provide new hope, while radical surgery remains the best option for improved survival.
- Advancements in imaging technologies and techniques, such as near-infrared fiberscopes, are enhancing surgeons' ability to achieve tumor-free margin resections during operations.

This study investigates the chemical complexity and toxicity of volatile organic compounds (VOCs) emitted from national petrochemical industrial parks and their effects on air quality in an industrial area of Nanjing, China. Field measurements were conducted from 1 December 2022, to 17 April 2023, focusing on VOC concentrations and speciations, diurnal variations, ozone formation potential (OFP), source identification, and associated health risks. The results revealed an average total VOC (TVOC) concentration of 15.
