BACKGROUND: A gunshot wound to the colon is a frequent injury in armed conflicts. An example of a high-energy modern weapon is hollow-point bullets, which is associated with increased tissue damage and lethal outcome. The aim of this study was to evaluate gunshot injuries to the colon in combat patients and to assess the difference in clinical features of patients with colon injuries by hollow-point versus shape-stable bullets. PATIENTS AND METHODS: Analyses of clinical data were performed on 374 male soldiers from the Armed Forces of Ukraine with gunshot abdominal wounds with injury to the colon in East Ukraine between 2014 and 2020...

As a disaster-prone country with unique geographical features, snake biting is a major public health concern in Bangladesh. The primary reasons of mortality from snakebite include late presentation to the hospital, low efficacy of antivenom, and a lack of adequate management facilities. Because snake venom characteristics vary depending on geographical location, antivenom should be manufactured from snakes native to the region in which it would be administered. Bungarus caeruleus is a highly venomous snake contributing to the major snakebite issue in Bangladesh...

BACKGROUND: The livestock sector contributes 1.90% to the GDP in Bangladesh during 2021-22. Poultry is one of the important subsectors struggling with diseases. Fowl adenoviruses (FAdVs) cause numerous diseases resulting in economic losses to the poultry industry worldwide. Several FAdV serotypes cause inclusion body hepatitis in chicken. Although FAdV infection was suspected, there was no confirmatory report from Bangladesh. The study was conducted to investigate the FAdV infection and antibodies in chicken...

Major trauma frequently occurs in the deployed, combat setting and is especially applicable in the recent conflicts with explosives dominating the combat wounded. In future near-peer conflicts, we will likely face even more profound weapons including mortars and artillery. As such, the number of severely wounded will likely increase. Hypocalcemia frequently occurs after blood transfusions, secondary to the preservatives in the blood products; however, recent data suggests major trauma in and of itself is a risk factor for hypocalcemia...

BACKGROUND: Traumatic brain injury (TBI) affects civilian and military populations with high morbidity and mortality rates and devastating sequelae. As the US military shifts its operational paradigm to prepare for future large-scale combat operations, the need for prolonged casualty care is expected to intensify. Identifying efficacious prehospital TBI management strategies is therefore vital. Numerous pharmacotherapies are beneficial in the inpatient management of TBI, including beta blockers, calcium channel blockers, statins, and other agents...

Background: Spontaneous simultaneous multiple intra-cerebral hemorrhages (SMICHs) and its occurrences in different territories of arterial disposition has been viewed as uncommon clinical occurrences, since the pathophysiological and predisposing factors as mechanisms aren't vividly defined. This research primarily aims for demographic stratification and dichotomization pertaining to risk factors, etiological classifications, anatomical distributions and outcome analysis by focusing on management strategies and pertinent stroke care...

Red blood cell (RBC) transfusion is a life-saving intervention for millions of trauma patients every year worldwide. While hemoglobin thresholds are clinically driving the need for RBC transfusion, limited information is available with respect to transfusion efficacy at the molecular level in clinically relevant cohorts. Here, we combined plasma metabolomic and proteomic measurements in longitudinal samples (n = 118; up to 13 time points; total samples: 690) from trauma patients enrolled in the control of major bleeding after trauma (COMBAT) study...

INTRODUCTION: Tranexamic acid (TXA) is a standard component of Tactical Combat Casualty Care. Recent retrospective studies have shown that TXA use is associated with a higher rate of venous thromboembolic (VTE) events in combat-injured patients. We aim to determine if selective administration should be considered in the prolonged field care environment. MATERIALS AND METHODS: We performed a systematic review using the 2020 Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines...

BACKGROUND AND PURPOSE: Traumatic hemorrhage (TH) is the leading cause of potentially preventable deaths that occur during the prehospital phase of care. No effective pharmacological therapeutics are available for critical TH patients yet. Here, we identify terminal complement activation (TCA) as a therapeutic target in combat casualties and evaluate the efficacy of TCA inhibitor (nomacopan) on organ damage and survival in vivo. EXPERIMENTAL APPROACH: Complement activation products and cytokines were analyzed in plasma from 54 combat casualties...

Vaccines to combat SARS-CoV-2 infection and the COVID-19 pandemic were quickly developed due to significant and combined efforts by the scientific community, government agencies, and private sector pharmaceutical and biotechnology companies. Following vaccine development, which took less than a year to accomplish, randomized placebo controlled clinical trials enrolled almost 100,000 people, demonstrating efficacy and no major safety signals. Vaccination programs were started, but shortly thereafter a small number of patients with a constellation of findings including thrombosis in unusual locations, thrombocytopenia, elevated D-dimer and often low fibrinogen led another intense and concentrated scientific effort to understand this syndrome...

BACKGROUND: Femur shaft fractures (FSF) are perceived as potentially life-threatening injuries due to significant blood loss. However, these injuries are rarely the sole cause of hemorrhagic shock. Clinical practice guidelines for the prehospital management of FSF are inconsistent, especially concerning the use and timing of traction splinting which is postulated to reduce bleeding. We sought to understand the association between FSF and shock, and identify risk factors for shock among casualties with FSF...

BACKGROUND: The MARCH (Massive hemorrhage, Airway, Respirations, Circulation, and Hypothermia/Head injuries) algorithm taught to military medics includes interventions to prevent hypothermia. As possible sequelae from major trauma, hypothermia is associated with coagulopathy and lower survival. This paper sought to define hypothermia within our combat trauma population using an outcomes-based method, and determine clinical variables associated with hypothermia. METHODS: This is a secondary analysis of a previously described dataset from the Department of Defense Trauma Registry focused on casualties who received prehospital care...

BACKGROUND: Transfusion of whole blood (WB) is a lifesaving treatment that prolongs life until definitive surgical intervention can be performed; however, collecting WB is a time-consuming and resource-intensive process. Furthermore, it may be difficult to collect sufficient WB at the point of injury to treat critically wounded patients or multiple hemorrhaging casualties. This study is a follow-up to the proof-of-concept study on the effect of airdrop on WB. In addition, this study confirms the statistical significance for the plausibility of using airdrop to deliver WB to combat medics treating casualties in the pre-hospital setting when Food and Drug Administration (FDA)-approved cold-stored blood products are not available...

Coronavirus disease 2019 (COVID-19) continues as an infectious pandemic. With emphasis on mitigating its impact globally, strategies have been emphasized on prevention to treatment in severe cases. As for pharmacotherapies, many have been researched, with a few being recommended for patients with COVID-19 depending upon their severity. Bevacizumab, a recombinant monoclonal antibody often used for oncological disease and rare genetic disorders, has gained attention in combatting COVID-19 due to the pharmacotherapy's ability to inhibit vascular endothelial growth factor A (VEGF-A)...

INTRODUCTION: Blood vessel injuries in modern military conflicts account for 12% of all wounds (1), and 50%-95% of these involve arterial damage in extremities (3, 5). Furthermore, 10%-15% of all deaths on the battlefield occur due to extremity hemorrhage (2). Therefore, tourniquets and compression dressings continue to be the main methods of controlling extremity hemorrhage (4). MATERIALS AND METHODS: The article analyzes the use of hemostatic tourniquets on wounded extremities for personnel that were provided second-level medical care by a Forward Surgical Team (FST) of one of the field hospitals of the Armed Forces of Ukraine...

Hemorrhage during accidents or surgery is a significant challenge that can contribute to mortality. This is further aggravated due to bacterial infections at the injured site. Therefore, rapid application of a hemostatic and antibacterial material is highly necessary as a pretreatment for patients' survival. Herein, we have developed a hemostatic sponge (Hemobac) through amide crosslinking of gelatin and an N -(2-hydroxy) propyl-3-trimethylammonium chitosan (HTCC)-silver chloride nanocomposite (QAm1 -Ag0.1 ) to mitigate bacterial infections, while aiding hemostasis...

IMPORTANCE: The most common cause of preventable death on the conventional battlefield or on special operations force (SOF) missions is hemorrhage. SOF missions may take place in remote and austere locations. Many preventable deaths in combat occur within 30 min of wounding. Therefore, SOF damage control resuscitation (DCR) and damage control surgery (DCS) teams may improve combat casualty survival in the SOF environment. OBJECTIVE: To determine the effect of SOF DCR and DCS teams on combat casualty survival...

BACKGROUND: Zone 1 resuscitative endovascular balloon occlusion of the aorta has been recommended for refractory shock after a dismounted complex blast injury for the austere combat scenario. While resuscitative endovascular balloon occlusion of the aorta should enhance coronary perfusion, there is a potential risk of secondary brain injury due to loss of cerebral autoregulation. We developed a combat casualty relevant dismounted complex blast injury swine model to evaluate the effects of resuscitative endovascular balloon occlusion of the aorta zone I on intracranial pressure and cerebral edema...
