Phospholipid Nanoparticles: A Novel Colloid for Blood Volume Replacement, Reanimation, and Organ Protection in Hemorrhagic Shock.

: Exsanguination is a leading cause of preventable death in military and civilian settings due to extensive blood loss and hemorrhagic shock, which trigger systemic effects such as impaired tissue perfusion, hypoxia, inflammation, and multi-organ dysfunction. Standard resuscitation restores blood volume but fails to address critical aspects of hemorrhagic shock, including inflammation, coagulopathy, and reperfusion injury. To address these limitations, novel phospholipid nanoparticle (PNP)-based resuscitative fluids, VBI-S and VBI-1, were developed to modulate nitric oxide (NO) levels, improving hemodynamic stability, tissue oxygenation, and reducing inflammatory injury.

Efficacy and safety of phospholipid nanoparticles (VBI-S) in reversing intractable hypotension in patients with septic shock: a multicentre, open-label, repeated measures, phase 2a clinical pilot trial.

Background: Since the 1990's attempts to favorably modulate nitric oxide (NO) have been unsuccessful. We hypothesized that because NO is lipophilic it would preferentially localize into intravascularly infused hydrophobic nanoparticles, thereby reducing its bioavailability and adverse effects without inhibiting its production. We aimed to determine the efficacy and safety of intravenous infusion of a fluid comprised of hydrophobic phospholipid nanoparticles (VBI-S) that reversibly absorb NO in the treatment of hypotension of patients in severe septic shock.

Evaluating skills for psychological recovery with gunshot injury survivors in a hospital-based early intervention program.

Gun violence is a serious public health problem that places surviving victims at increased risk for a variety of mental health problems, including posttraumatic stress disorder (PTSD) and depression. Recognizing that many gunshot injury survivors lack access to mental health care in the early aftermath of a shooting, there has been growing interest in the use of early, preventive mental health interventions to help prevent long-term mental health complications like PTSD as part of routine care for survivors in acute medical settings, where initial outreach to survivors may be more successful. This study evaluates clinical outcomes associated with one such early intervention-Skills for Psychological Recovery (SPR)-provided to gunshot injury survivors as part of a hospital-based early intervention program embedded in a Level 1 trauma center in the Midwestern United States.
