PURPOSE OF REVIEW: The study aims to describe the evidence-based management and controversies in blunt splenic trauma. RECENT FINDINGS: A shift from operative management to non-operative management (NOM) has occurred over the past decades where NOM has now become the standard of care in haemodynamically stable patients with blunt splenic injury. Splenic artery embolisation (SAE) is generally believed to increase the success rate of NOM. Not all the available evidence is that optimistic about SAE however...

Brucellosis remains as a significant public health concern in many areas where the infection persists in domestic hosts (i.e. goats, cattle, and domestic swine) with subsequent risk of transmission to human populations. Brucellosis caused by B. suis remains an important threat to human populations in many countries exposed to domestic and feral swine. In the U.S., swine brucellosis has been under control for many years. Meanwhile, it is a widespread infection among feral swine, particularly in the Southeastern United States; and exposure to infected animals pose a growing threat to humans...

The purpose of this study was to evaluate burn-related variations of inflammation and immunity. Fifty-five mice were divided randomly into sham burn and burn groups. Eighty-seven hospitalized burn patients were also reviewed. In mice, neutrophils and monocytes were elevated significantly on post burn day (PBD 1). Lymphocytes were reduced on PBDs 1 and 3. Levels of serum tumor necrosis factor-α and interleukin-6 were highest on PBD 1. Interleukin-1β levels were the highest on PBD 3. On PBD 3, CD4CD25T regulatory cells/CD4 cells in spleen were higher...

Repair of the lung epithelium after injury is a critical component for resolution; however, the processes necessary to drive epithelial resolution are not clearly defined. Published data demonstrate that Foxp3+ regulatory T cells (Tregs) enhance alveolar epithelial proliferation after injury, and Tregs in vitro directly promote type II alveolar epithelial cell (AT2) proliferation in part by a contact-independent mechanism. Therefore, we sought to determine the contribution of Treg-specific expression of a growth factor, keratinocyte growth factor (Kgf), known to be important in lung repair...

Ischemia reperfusion injury (IRI) evokes intra-graft inflammatory responses, which markedly augment alloimmune responses against the graft. Understanding the mechanisms underlying these responses is fundamental to develop therapeutic regimens to prevent/ameliorate organ IRI. Here, we demonstrate that IRI results in a marked increase in mitochondrial damage and autophagy in dendritic cells (DC). While autophagy is a survival mechanism for ischemic DC, it also augments their production of IL6. Allograft derived dendritic cells (ADDC) lacking autophagy related gene 5 (Atg5) showed higher death rates post-transplantation...

INTRODUCTION: The management of blunt splenic injuries (BSI) has evolved toward strategies that avoid splenectomy. There is growing adoption of interventional radiology (IR) techniques in non-operative management of BSI, with evidence suggesting a corresponding reduction in emergency laparotomy requirements and increased splenic preservation rates. Currently there are no UK national guidelines for the management of blunt splenic injury. This may lead to variations in management, despite the reorganisation of trauma services in England in 2012...

C1 neurons, located in the medulla oblongata, mediate adaptive autonomic responses to physical stressors (for example, hypotension, hemorrhage and presence of lipopolysaccharides). We describe here a powerful anti-inflammatory effect of restraint stress, mediated by C1 neurons: protection against renal ischemia-reperfusion injury. Restraint stress or optogenetic C1 neuron (C1) stimulation (10 min) protected mice from ischemia-reperfusion injury (IRI). The protection was reproduced by injecting splenic T cells that had been preincubated with noradrenaline or splenocytes harvested from stressed mice...

We report the experience of a Level I trauma center in the management of blunt renal injury during a 5-year period, with special attention to those treated using angiography with embolization. The institutional trauma registry was queried for all patients with blunt renal injury between September 1, 2009 and August 30, 2014. Each injury was graded using the American Association for the Surgery of Trauma guidelines. Patients that underwent angiography with embolization were reviewed for case-specific information including imaging findings, treatment, materials used, clinical course, and mortality...

Portal hypertension induces congestion of the liver and spleen, thus any capsular or parenchymal injury to these organs can produce intractable bleeding which generally is not easily controlled. To cope with intractable bleeding such as being encountered during liver transplantation, we developed an infiltrating hemostasis technique as a conceptual shift from conventional application methods, in which fibrin glue is locally injected into the bleeding area on the liver or spleen. This technique, which uses a fibrin glue kit (2 ml kit; Greenplast, Green Cross, Seoul, Korea), consists of inserting the needle 0...

The classical pathway (CP) of complement is believed to significantly contribute to alloantibody-mediated transplant injury, and targeted complement inhibition is currently considered to be a promising approach for preventing rejection. Here, we investigated the mode of action and efficacy of the humanized anti-C1s monoclonal antibody TNT009 and its parental mouse variant, TNT003, in preclinical in vitro models of HLA antibody-triggered CP activation. In flow cytometric assays, we measured the attachment of C1 subcomponents and C4/C3 split products (C4b/d, C3b/d) to HLA antigen-coated flow beads or HLA-mismatched aortic endothelial cells and splenic lymphocytes...

BACKGROUND: Inappropriately sustained inflammation is a hallmark of chronic ischemic heart failure (HF); however, the pathophysiological role of T lymphocytes is unclear. METHODS AND RESULTS: Permanent coronary ligation was performed in adult C57BL/6 mice. When compared with sham-operated mice, mice with HF (8 weeks after ligation) exhibited the following features: (1) significant (P<0.05) expansion of circulating CD3(+)CD8(+) cytotoxic and CD3(+)CD4(+) helper (Th) T lymphocytes, together with increased Th1, Th2, Th17, and regulatory T-cell (Treg) CD4(+) subsets; (2) significant expansion of CD8(+) and CD4(+) T cells in failing myocardium, with increased Th1, Th2, Th17, and Treg CD4(+) subsets, marked reduction of the Th1/Th2 ratio, augmentation of the Th17/Treg ratio, and upregulation of Th2 cytokines; and (3) significantly increased Th1, Th2, Th17 cells, and Tregs, in the spleen and mediastinal lymph nodes, with expansion of splenic antigen-experienced effector and memory CD4(+) T cells...

BACKGROUND: Traumatic rib fractures can cause chest complications that need further treatment and hospitalization. We hypothesized that an increase in the number of displaced rib fractures will be accompanied by an increase in chest complications. METHODS: We retrospectively reviewed the trauma registry between January 2013 and May 2015 in a teaching hospital in northeastern Taiwan. Patients admitted with chest trauma and rib fractures without concomitant severe brain, splenic, pelvic or liver injuries were included...

We have previously shown that fresh frozen plasma (FFP) and lyophilized plasma decrease brain lesion size and improve neurologic recovery in a swine model of traumatic brain injury (TBI) and hemorrhagic shock (HS). In this study, we examine whether these findings can be validated in a clinically relevant model of severe TBI, HS, and polytrauma. Female Yorkshire swine were subjected to TBI (controlled cortical impact), hemorrhage (40% volume), grade III liver and splenic injuries, rib fracture, and rectus abdominis crush...

Although it is well established that acute kidney injury (AKI) is a proinflammatory state, little is known about the endogenous counter-inflammatory response. IL-6 is traditionally considered a pro-inflammatory cytokine that is elevated in the serum in both human and murine AKI. However, IL-6 is known to have anti-inflammatory effects. Here we sought to investigate the role of IL-6 in the counter-inflammatory response after AKI, particularly in regard to the anti-inflammatory cytokine IL-10. Ischemic AKI was induced by bilateral renal pedicle clamping...

INTRODUCTION: Delayed splenic rupture (DSR) is an unusual outcome following blunt abdominal trauma. Although DSR is defined as bleeding more than 48 hours after blunt trauma in a previously hemodynamically stable patient, a review of the reported cases in the literature shows that in almost all of the cases the initial CT imaging revealed some form of damage to the spleen. CASE PRESENTATION: Here we describe an extremely rare condition in a case that presented with a DSR following blunt trauma and had a normal appearing spleen in the initial post trauma MDCT scan...

Activated T cells play crucial roles in the pathogenesis of autoimmune diseases, including lupus nephritis (LN). The activation of calcineurin/nuclear factor of activated T cells (NFAT) and STAT4 signaling is essential for T cells to perform various effector functions. Here, we identified the growth factor midkine (MK; gene name, Mdk) as a novel regulator in the pathogenesis of 2,6,10,14-tetramethylpentadecane-induced LN via activation of NFAT and IL-12/STAT4 signaling. Wild-type (Mdk(+/+)) mice showed more severe glomerular injury than MK-deficient (Mdk(-/-)) mice, as demonstrated by mesangial hypercellularity and matrix expansion, and glomerular capillary loops with immune-complex deposition...
