Abstract
BACKGROUND Terrorist attacks have the potential to be mass casualty events, causing multiple injuries and deaths. High injury rate attacks will particularly place a high burden on emergency medical systems. This study aimed to assess if there is a difference between attacks with high injury rates and high fatality rates. METHODS The top 100 terrorist events causing the highest number of fatalities versus the highest number of injuries were selected from the Global Terrorism Database. Analyses were performed on temporal factors, location, target type, attack and weapon type, and perpetrator type. RESULTS The 9/11 attacks caused the highest number of both fatalities and injuries. With regards to injury rates, the sarin attacks in Tokyo, Japan ranked second. Events with high fatality rates were overrepresented in Sub-Saharan Africa, whereas events with high injury rates were predominant in the Middle East & North Africa. High fatality rates were most often associated with armed assaults and hostage takings. Bombings were responsible for the highest number of injuries. CBRN attacks were overrepresented in the top 100 injuries, and accounted for 11% of the incidents. CONCLUSION High injury rate incidents place a heavy burden on the health care system as the number of injuries is nearly ten times as high as the number of injuries in high fatality rate incidents. Epidemiological analysis of high impact terrorist events may contribute to counter-terrorism preparedness, to an increased focus on dealing with CBRN-events, and thus to a proper medical response to future terrorist events.

Abstract
During the last few decades, the increasing use of asymmetric and multimodal tactics by terrorists has led anesthesiologists worldwide to analyze and discuss their role in mass casualty scenarios in more depth. Now anesthesiologists must address the new situation of hybrid threats and hybrid warfare. This will have a direct impact on anesthesiology and intensive care, and in the end, the health and well-being of critical patients of all ages. To be able to respond to a hybrid threat efficiently and effectively, it is imperative that anesthesiologists play an early and integral role in mitigation and response planning.

Abstract
BACKGROUND Russia's annexation of Crimea in 2014, and the recent Russo-Ukrainian war that started in 2022, were triggers that radically changed the perception of security in the Nordic and Baltic countries. The on-going Russian hybrid war has resulted in a renewed global interest in the safety and security of many countries (eg, the Nordic-Baltic Eight). The prospective North Atlantic Treaty Organization (NATO) membership of Finland and Sweden may drastically change the regional military and political landscape.The objective of this study was to identify and characterize all documented terrorist attacks in this region as reported to the Global Terrorism Database (GTD) from 1970 through 2020. METHODS The GTD was searched using the internal database functions for all terrorism incidents in the Nordic-Baltic states: Denmark, Estonia, Finland, Iceland, Latvia, Lithuania, Norway, and Sweden.Temporal factors, location, target type, attack and weapon type, perpetrator type, number of casualties, and property value loss were collated. Results were exported into an Excel spreadsheet for analysis. RESULTS There were 298 terrorism-related incidents from 1970 through 2020. Most attacks occurred in Sweden, followed by Norway and Finland. No entries were recorded for the Baltic states prior to their independency in 1991. The 298 incidents resulted in a total of 113 fatalities and 277 injuries.Facility/infrastructure attacks were the most frequently identified attack type (35.0%), followed by bombings and explosions (30.9%). Armed assaults were responsible for 80 fatalities and 105 injuries, followed by bombings/explosions with 15 fatalities and 72 injuries. The predominant target types were immigrants and refugee shelters (64/298 incidents). In only 33.6% of the incidents, perpetrators were known. Right-wing assailants represented the largest group, accounting for 27 incidents. CONCLUSION From 1970 through 2020, there were 298 terrorist attacks in the Nordic-Baltic Eight. Sweden accounted for 50% of incidents.The profile of terrorist attacks was very diverse, as were the perpetrators and targets. Every country had its own incident characteristics. The surge of right-wing extremism must be closely monitored.

Abstract
INTRODUCTION The use of chemical, biological, radiation, and nuclear (CBRN) weapons is not new, and though rare, it is an issue of concern around the world due to their ability to cause large-scale mass-casualty events and their potential threat to global stability. The purpose of this study is to explore the use of CBRN weapons by non-state actors through analysis of the Violent Non-State Actor (VNSA) CBRN Event database, and aims to better inform health care systems of the potential risks and consequences of such events. METHODS Data collection was performed using a retrospective database search through the VNSA CBRN Event database. RESULTS A total of 565 events were recorded. Five hundred and five (505) events (89.4%) involved single agents while 60 events (10.6%) involved multiple agents. Fatalities numbered 965 for chemical agents, 19 for biological agents, and none for radiological and nuclear events. Injuries numbered 7,540 for chemical agents, 59 for biological agents, 50 for radiological events, and none for nuclear attacks. Fatality and injury per attack was 2.22 and 17.37, respectively, for chemical event agents and 0.15 and 0.48, respectively, for biological event agents. CONCLUSION Violent Non-State Actors were responsible for 565 unique events around the world involving the use of CBRN weapons from 1990-2020. The United States (118), Russia (49), and Iraq (43) accounted for the top three countries where these events occurred. While CBRN events remain relatively rare, technological advances have the potential to facilitate the use of such weapons as part of a hybrid warfare strategy with significant repercussions for civilian health and health care systems.

Abstract
INTRODUCTION Cyberattacks are one of the most widespread, damaging, and disruptive forms of action against healthcare entities. Data breaches, ransomware attacks, and other intrusions can lead to significant cost both in monetary and personal harm to those affected and may result in large payouts to cyber criminals, crashes of information technology systems, leaks of protected health and personal information, as well as fines and lawsuits. This study is a descriptive analysis of healthcare-related cyber breaches affecting 500 or more individuals in the past decade in the United States. METHODS The publicly available U.S. breach report database was downloaded in the Microsoft Excel (Microsoft, Redmond, Washington, USA) format and searched for all reported breaches occurring between January 1, 2011 - December 31, 2021 (10 years). Breaches were subdivided by category and analyzed by states, breach submission dates, types of breach, location of breached information, entity type, and individuals affected. All subcategories were predefined by the breach report. RESULTS There were a total of 3822 PHI breaches that affected 283,335,803 people in the United States from January 1, 2011 to December 31, 2021. Of the 3822 PHI breaches, 1593 (41.7%) were hacking/ IT related, 1055 (27.6%) were listed as unknown, 819 (21.4%) were theft related, 194 (5.1%) were loss related, 97 (2.5%) were related to improper disposal and 64 (1.7%) were listed as "others". Year 2020 saw the most breaches with 631 and California was the state with the highest number of breaches at 403. CONCLUSION Cyberattacks and healthcare breaches are one of the most costly and disruptive situations facing healthcare today. A total of 3822 breaches affecting 283,335,803 people in the United States were recorded from January 1, 2011 to December 31, 2021. By understanding the extent of cyberthreats this will better prepare healthcare organizations and providers to mitigate, respond, and recover from these devastating attacks.

Abstract
INTRODUCTION March 9, 2022. An airstrike by Russian forces destroying a maternity hospital in Mariupol, Ukraine. The image of a severely injured pregnant woman covered in blood being stretchered away against the backdrop of destroyed buildings. Mutterings of the use of chemical weapons. This paper is a primer for healthcare personnel and health systems on hybrid warfare and counter-terrorism medicine. DISCUSSION While recent events and images arising from conflicts around the world represent a cruel hallmark in today's history, attacks against healthcare facilities and innocent civilians are not new and continue to be perpetrated around the world. In war, the Geneva Convention protects civilians and healthcare institutions from harm but when war crimes are being committed and civilians knowingly targeted, parallels from a healthcare perspective can be drawn with terrorism events. Increasingly, civilian institutions and in particular the healthcare sector, are drawn into such conflicts and understanding the health system impact of hybrid warfare and other asymmetrical attack methods is of great importance. CONCLUSION The field of Counter-Terrorism Medicine (CTM) explores the healthcare impacts of intentional, man-made attacks and much recent research and discussions around this topic are extremely relevant and applicable not just to the ongoing hybrid war in Ukraine, but to today's threat climate all around us.

Abstract
Acute pulmonary embolism (PE) is a common emergency with a high morbidity and mortality. Most clinical presentations are non-specific and there is a lack of suitable biomarkers for PE. For example, the traditional D-dimer tests shows a rather high sensitivity for PE, but yet a rather low positive predictive value due to its lack of specificity. Research on novel biomarkers for PE is thus of interest to improve early diagnostics and reduce the number of unnecessary computed tomography pulmonary angiogram (CTPA) scans performed. In this study we evaluate the feasibility to use label-free quantitative proteomics to discover potential biomarkers for acute PE and to monitor changes in proteins levels in PE patients over time. Blood was collected from 8 patients with CTPA verified PE and from 8 patients presenting with same symptoms but with a negative CTPA. The samples were analyzed by liquid chromatography-mass spectrometry and thirteen protein concentrations were found to be significantly changed in PE patients compared to the CTPA negative controls. This exploratory study shows that proteomic analysis can be used to identify potential biomarkers for PE as well as to monitor changes of protein levels over time.The complement proteins play a part in PE but further studies are needed to clarify their specific role in the pathophysiological process and to look for more specific proteins.

Abstract
Concussion is common in many sports, and the incidence is increasing. The medical consequences after a sport-related concussion have received increased attention in recent years since it is known that concussions cause axonal and glial damage, which disturbs the cerebral physiology and makes the brain more vulnerable for additional concussions. This study reports on a knocked-out amateur boxer in whom cerebrospinal fluid (CSF) neurofilament light (NFL) protein, reflecting axonal damage, was used to identify and monitor brain damage. CSF NFL was markedly increased during 36 weeks, suggesting that neuronal injury persists longer than expected after a concussion. CSF biomarker analysis may be valuable in the medical counselling of concussed athletes and in return-to-play considerations.
