Context: Recombinant factor VIIa (rFVIIa) has been used as an adjunctive therapy for acute post-traumatic hemorrhage and reversal of iatrogenic coagulopathy in trauma patients in the hospital setting. However, investigations regarding its potential use in pre-hospital management of traumatic brain injury (TBI) have not been conducted extensively.
Aims: In the present study, we investigated the physiology, hematology and histology effects of a single pre-hospital bolus injection of rFVIIa compared to current clinical practice of no pre-hospital intervention in a swine model of moderate fluid percussion TBI.
Materials And Methods: Animals were randomized to receive either a bolus of rFVIIa (90 μg/kg) or nothing 15 minutes (T15) post-injury. Hospital arrival was simulated at T60, and animals were euthanized at experimental endpoint (T360).
Results: Survival was 100% in both groups; baseline physiology parameters were similar, vital signs were comparable. Animals that received rFVIIa demonstrated less hemorrhage in subarachnoid space (P = 0.0037) and less neuronal degeneration in left hippocampus, pons, and cerebellum (P = 0.00009, P = 0.00008, and P = 0.251, respectively). Immunohistochemical staining of brain sections showed less overall loss of microtubule-associated protein 2 (MAP2) and less Flouro-Jade B positive cells in rFVIIa-treated animals.
Conclusions: Early pre-hospital administration of rFVIIa in this swine TBI model reduced neuronal necrosis and intracranial hemorrhage (ICH). These results merit further investigation of this approach in pre-hospital trauma care.

Cutaneous leishmaniasis (CL) is a tropical disease that can cause chronic lesions and leave life-long scars, leading to social stigmatization and psychological disorders. Using growth factors and immunomodulatory agents that could accelerate wound healing and reduce the scar is highly demanded. Epidermal growth factor (EGF) plays an essential role in wound healing.

This split-mouth trial investigated the efficacy of treating bilateral gingival recessions with either a xenogeneic cross-linked collagen matrix (CCM), or recombinant human platelet derived growth factor (rhPDGF-BB) with a bone allograft (AG). Ten patients were treated with the coronally advanced flap (CAF), either with a CCM, or rhPDGF-BB + AG. The primary outcome was percentage of mean root coverage (mRC) at 12 months.

Purpose Of Review: This review aims to examine recent advances in the understanding of injury-induced endotheliopathy and therapeutics to mitigate its development in critically injured patients.
Recent Findings: Clinical studies have clearly demonstrated that syndecan-1 ectodomains can be found in circulation after various types of trauma and injury and correlates with worse outcomes. As the mechanisms of endotheliopathy are better understood, pathologic hyperadhesive forms of von Willebrand factor, along with a relative deficiency of its cleaving enzyme, a disintegrin and metalloprotease with thrombospondin type I motifs, member 13 (ADAMTS13), have emerged as additional biomarkers.

Urban domestic dog populations can provide important clues about the eco-epidemiological characteristics of Trypanosoma cruzi, the causative agent of Chagas disease (ChD). Given the limited data on ChD from the Metropolitan Area of Mendoza, Argentina, a seroprevalence survey of 327 dogs across an urban-rural gradient was conducted between April 2018 and May 2019. Seropositive cases were analyzed considering host, social, and environmental factors, subtypes (DTUs), and bloodstream parasite load.

is a bacterium associated with colorectal cancer (CRC) tumorigenesis, progression, and metastasis. Fap2 is a fusobacteria-specific outer membrane galactose-binding lectin that mediates adherence to and invasion of CRC tumors. Advances in omics analyses provide an opportunity to profile and identify microbial genomic features that correlate with the cancer-associated bacterial virulence factor Fap2.
