Article Synopsis
  • - Severe traumatic brain injury (TBI) has a high mortality rate of about 25-30%, and despite extensive research, effective drug therapies have not yet emerged due to factors like relying on specific-pathogen free (SPF) animals and a narrow focus in drug design.
  • - The progression of TBI involves a cascade of damaging processes such as ischemia, inflammation, and immune dysfunction, which lead to further complications and reduced outcomes for patients.
  • - Researchers propose that early intervention to correct sympathetic hyperactivity and immune activation can improve recovery, and they are developing a fluid therapy (adenosine, lidocaine, and magnesium) that has shown promise in minimizing secondary injury and supporting cardiovascular function in TBI cases. *

The main problem of vascular preservation is the maintenance of vessel graft quality and function following extended storage. Conventional preservation solutions such as histidine-tryptophan-ketoglutarate (HTK) solution, Phosphate-Buffer Solution (PBS), or sodium chloride 0.9% has been shown to be inadequate in preserving vascular physiological function after 3 days of cold storage.

Article Synopsis
  • Non-compressible torso hemorrhagic (NCTH) shock is a leading cause of death in battlefield trauma, making the development of new resuscitation therapies essential, especially focusing on drugs like adenosine, lidocaine, and magnesium (ALM).
  • A literature review explored the effects of permissive hypotension, while a preclinical study on female pigs examined the efficacy of a fluid resuscitation protocol involving 3% NaCl with or without ALM.
  • Results indicated that achieving a mean arterial pressure (MAP) of about 50 mmHg could either be beneficial or harmful, depending on cardiac output and systemic vascular resistance, with ALM therapy improving oxygen delivery and survival rates by enhancing heart function and reducing internal bleeding.

For decades, left ventricular ejection fraction (LVEF < 35%) has been a mainstay for identifying heart failure (HF) patients most likely to benefit from an implantable cardioverter defibrillator (ICD). However, LVEF is a poor predictor of sudden cardiac death (SCD) and ignores 50% of HF patients with mildly reduced and preserved LVEF. The current international guidelines for primary prophylaxis ICD therapy are inadequate.

Spontaneous regression (SR) of chronic lymphocytic leukemia (CLL) is a rare event (0.2% - 1%). Some advances have been made in understanding the tumor genetic characteristics of such patients, although the immunological mechanisms leading to SR remain unclear.

Aims: Adenosine, lidocaine, and Mg (ALM) therapy exerts differential immuno-inflammatory responses in males and females early after anterior cruciate ligament (ACL) reconstruction (ACLR). Our aim was to investigate sex-specific effects of ALM therapy on joint tissue repair and recovery 28 days after surgery.

Methods: Male (n = 21) and female (n = 21) adult Sprague-Dawley rats were randomly divided into ALM or Saline control treatment groups.

Objective: To identify and describe differences in demographics, injury characteristics, and outcomes between rural and urban patients suffering brain injury.

Data Sources: CINAHL, Emcare, MEDLINE, and Scopus.

Review Methods: A systematic review and meta-analysis of studies comparing epidemiology and outcomes of rural and urban brain trauma was conducted in accordance with PRISMA and MOOSE guidelines.

Severe infection and sepsis are medical emergencies. High morbidity and mortality are linked to CNS dysfunction, excessive inflammation, immune compromise, coagulopathy and multiple organ dysfunction. Males appear to have a higher risk of mortality than females.

Adenosine, lidocaine and Mg (ALM) solution is an emerging therapy that reduces secondary injury after intravenous administration in experimental models of traumatic brain injury (TBI). Intranasal delivery of ALM may offer an alternative route for rapid, point-of-care management of TBI. As a preliminary safety screen, we evaluated whether ALM exerts cytotoxic or inflammatory effects on primary human nasal epithelial cells (pHNEC) in vitro.

Severe burn injury elicits a profound stress response with the potential for high morbidity and mortality. If polytrauma is present, patient outcomes appear to be worse. Sex-based comparisons indicate females have worse outcomes than males.

Background: Head trauma is a leading cause of death and disability worldwide. Young males, Indigenous people, and rural/remote residents have been identified as high-risk populations for head trauma, however, Australian research is limited. Our aim was to define and describe the incidence, demographics, causes, prehospital interventions, and outcomes of head trauma patients transported by aeromedical services within North Queensland, Australia.

If a trauma (or infection) exceeds the body's evolutionary design limits, a stress response is activated to quickly restore homeostasis. However, when the injury severity score is high, death is often imminent. The goal of this review is to provide an update on the effect of small-volume adenosine, lidocaine and Mg (ALM) therapy on increasing survival and blunting secondary injury after non-compressible hemorrhagic shock and other trauma and infective/endotoxemic states.

Introduction: The binding of drugs to plasma proteins is an important consideration in drug development. We have reported that the dose of adenosine, lidocaine, and magnesium (ALM) fluid therapy for resuscitation from hemorrhagic shock is nearly 3-times higher for pigs than rats. Since lidocaine strongly binds to serum alpha-1-acid glycoprotein (AGP), the aim of the study was to investigate the effect of hemorrhagic shock on levels of AGP in rats and pigs.

The management of severe burns remains a complex challenge. Adenosine, lidocaine, and magnesium (ALM) resuscitation therapy has been shown to protect against hemorrhagic shock and traumatic injury. The aim of the present study was to investigate the early protective effects of small-volume ALM fluid resuscitation in a rat model of 30% total body surface area (TBSA) thermal injury.

Objective: The objective of this study was to investigate the genetic control of polyphenol accumulation in red raspberry (Rubus idaeus L).

Methods: The levels of total anthocyanins and 37 individual polyphenol metabolites were measured over three years in a raspberry biparental mapping population. Quantitative trait loci (QTLs) for these traits were mapped onto a high-density SNP linkage map.

Background: A novel buprenorphine (BUP) extended-release formulation (BUP-XR) produced as a lipid-encapsulated, low viscosity BUP suspension for subcutaneous (SC) injection to control pain was evaluated for pharmacokinetics and safety in four adult male cynomolgus monkeys.

Methods: Each animal was given 0.2 mg/kg reformulated BUP-XR SC.

Skeletal muscle trauma is a common injury with a range of severity. Adenosine, lidocaine and Mg (ALM) is a protective solution and improves tissue perfusion and coagulopathy. Male Wistar rats were anesthetized and subjected to standardized skeletal muscle trauma of the left soleus muscle with the protection of the neurovascular structures.
