Purpose Of Review: This review aims to understand the foundations of cognitive behavioral therapy (CBT) and biofeedback, their indications for therapy, and evidence-based support.

Recent Findings: Both CBT and biofeedback are noninvasive therapy options for patients who are suffering from a variety of chronic pain conditions, including chronic low back pain, headache, fibromyalgia, and temporomandibular disorder (TMD). CBT has been shown to be effective in treating multiple chronic pain conditions.

Background: Blood shortages and utilization stewardship have motivated the trauma community to evaluate futility cutoffs during massive transfusions (MTs). Recent single-center studies have confirmed meaningful survival in ultra-MT (≥20 U) and super-MT (≥50 U), while others advocate for earlier futility cut points. We sought to evaluate whether transfusion volume and intensity cut points could predict 100% mortality in a multicenter analysis.

Background: The use of low titer group O whole blood (LTOWB) for resuscitation of patients with traumatic hemorrhage is becoming increasingly common. Practices regarding the administration of RhD-positive LTOWB to childbearing age females (CBAFs) vary between institutions due to concerns about RhD alloimmunization. This study examined practices related to LTOWB transfusion as they pertain to age and sex.

A biomimetic synthesis of the marine thioalkaloids dassonmycins A and B is reported. The synthesis features a chemoselective reduction of a diketopiperazine to form a 2-piperazinone, which undergoes heteroannulation with naphthoquinone to yield dassonmycin A. Dassonmycin A undergoes slow cyclization to form dassonmycin B at physiological pH, supporting a biosynthesis hypothesis that this reaction could occur in the cytosol of the bacterial host species.

Organic synthesis has historically relied on solution-phase, polar transformations to forge new bonds. However, this paradigm is evolving, propelled by the rapid evolution of radical chemistry. Additionally, organic synthesis is witnessing a simultaneous resurgence in mechanochemistry, the formation of new bonds in the solid-state, further contributing to this shift in the status quo.

Objectives: The delta shock index (ΔSI), defined as the change in shock index (SI) over time, is associated with hospital morbidity and mortality, but prehospital studies about ΔSI are limited. We investigate the association of prehospital ΔSI with mortality and resource utilization, hypothesizing that increases in SI among field trauma patients are associated with increased mortality and blood product transfusion.

Methods: We performed a multicenter, retrospective, observational study from the Linking Investigators in Trauma and Emergency Services (LITES) network.

Article Synopsis
  • Traumatic brain injury (TBI) and hemorrhage significantly contribute to trauma-related fatalities, especially in patients with polytrauma, leading researchers to explore better diagnostic and prognostic methods.
  • The study utilized blood samples from a cohort to assess the predictive ability of glial fibrillary acidic protein (GFAP) and ubiquitin C-terminal hydrolase L1 (UCH-L1) levels in patients experiencing hemorrhagic shock, with or without TBI, through classification tree analysis.
  • Results indicated that GFAP levels, particularly greater than 286 pg/ml at patient arrival, effectively predicted TBI presence and associated outcomes, whereas UCH-L1 did not show significant predictive value in the studied scenarios.

Objectives: The prehospital prediction of the radiographic diagnosis of traumatic brain injury (TBI) in hemorrhagic shock patients has the potential to promote early therapeutic interventions. However, the identification of TBI is often challenging and prehospital tools remain limited. While the Glasgow Coma Scale (GCS) score is frequently used to assess the extent of impaired consciousness after injury, the utility of the GCS scores in the early prehospital phase of care to predict TBI in patients with severe injury and concomitant shock is poorly understood.

Background: The reporting of adverse events (AEs) is required and well defined in the execution of clinical trials, but is poorly characterized particularly in prehospital trials focusing on traumatic injury. In the setting of prehospital traumatic injury trials, no literature currently exists analyzing the clinical implications of AEs and their associations with mortality and morbidity. We sought to analyze AEs from three prehospital hemorrhagic shock trials and characterize their time course, incidence, severity, associated clinical outcomes, and relatedness.

Article Synopsis
  • The study focuses on improving resuscitation methods to minimize inflammation and organ damage after severe trauma-related blood loss.
  • Researchers connected animal study data with real patient data from a trauma study using a mathematical model to analyze inflammation and coagulation responses.
  • The model effectively predicted outcomes and showed that resuscitation with both plasma and red blood cells was more effective than using crystalloid solutions alone, while early plasma use improved survival and reduced injury severity.

Analysis of environmental DNA (eDNA) has been successfully used across freshwater ecological parasitology to inform management of ecologically and economically important species. However, most studies have used species-specific quantitative polymerase chain reaction (qPCR) assays to detect target taxa. While generally effective, this approach limits the amount of community and management-supporting data that can be obtained from eDNA samples.

Article Synopsis
  • The study aimed to assess how whole blood (WB) transfusions influence mortality rates in trauma patients when used alongside blood components.
  • Key findings showed that using WB was linked to significantly lower mortality within 4 hours, 24 hours, and 30 days after trauma compared to transfusing only blood components.
  • Additionally, higher ratios of WB to total transfusion volume (WB:TTV) and balanced blood component transfusions combined with WB were also associated with reduced mortality rates in critically injured patients.

Introduction: Recent randomized clinical trials have demonstrated that prehospital tranexamic acid (TXA) administration following injury is safe and improves survival. However, the effect of prehospital TXA on adverse events, transfusion requirements, and any dose-response relationships require further elucidation.

Methods: A secondary analysis was performed using harmonized data from two large, double-blinded, randomized prehospital TXA trials.

Background: Direct oral anticoagulants (DOACs) are the preferred treatment for venous thromboembolism (VTE). However, DOAC use in patients with a BMI greater than 40 kg/m has not been well studied despite the growing prevalence of obesity, and current literature is often underpowered.

Methods: This multicenter, retrospective, observational study evaluated patients 18 years and older who received DOACs for acute VTE treatment.

Background: Tranexamic acid (TXA) has been hypothesized to mitigate coagulopathy in patients after traumatic injury. Despite previous prehospital clinical trials demonstrating a TXA survival benefit, none have demonstrated correlated changes in thromboelastography (TEG) parameters. We sought to analyze if missing TEG data contributed to this paucity of findings.

Article Synopsis
  • The study looked at how different types of injuries (blunt vs. penetrating) affect patients in clinical trials for trauma.
  • Researchers found that patients with blunt injuries had a higher chance of dying within 30 days compared to those with penetrating injuries (29.7% vs. 14.0%).
  • They also noticed that certain markers in the blood, which indicate cell damage, were higher in patients with blunt injuries.

Objective: Treating traumatic hemorrhage is time sensitive. Prehospital care and transport modes (eg, helicopter and ground) may influence in-hospital events. We hypothesized that prehospital time (on-scene time [OST] and total prehospital time [TPT]) and transport mode are associated with same-day transfusion and mortality.

Herein we report unanticipated results that emerged from a synthetic study targeting the unique triazocane present in the hicksoane alkaloids. An initial strategy focused on the cyclisation-ring expansion of a 3-(tryptophyl)imidazolidin-4-one failed due to the high reactivity of the imide unit; passing a methanolic solution of this compound through a weakly basic ion exchange resin led to methanolysis to form a (tryptophanamido)methylglycinate. Attempted lactamisation of this (tryptophanamido)methylglycinate led to the formation of a (tryptophyl)imidazolidin-4-one, a rare imidazopyrido[3,4-]indolone and a β-carboline.

Per- and polyfluoroalkyl substances (PFASs) are a class of synthetic chemicals of concern that exhibit extreme persistence within the environment and possess physicochemical properties that are resistant to targeted degradation. Comprising substantial concentrations of PFASs, aqueous film-forming foams (AFFFs) present a major exposure pathway to the environment having been applied to land at firefighting-training sites globally for decades. This has led to significant contamination of environmental media.
