In this paper we study antibiotic-induced C. difficile infection (CDI), caused by the toxin-producing C. difficile (CD), and implement clinically-inspired simulated treatments in a computational framework that synthesizes a generalized Lotka-Volterra (gLV) model with SIR modeling techniques. The gLV model uses parameters derived from an experimental mouse model, in which the mice are administered antibiotics and subsequently dosed with CD. We numerically identify which of the experimentally measured initial conditions are vulnerable to CD colonization, then formalize the notion of CD susceptibility analytically...

BACKGROUND: Neuroendocrine tumors (NETs) metastasize to the liver. Everolimus and selective internal radioembolization (SIRT) are approved treatments. Pasireotide is a somatostatin analogue with an affinity for somatostatin receptors 1, 2, 3, and 5. Everolimus and pasireotide may potentiate SIRT radiosensitization and inhibit rebound angiogenesis. This study evaluated the safety of pasireotide, everolimus, and SIRT. METHODS: This 3 + 3 phase 1 trial evaluated 3 dose levels of everolimus (2...

BACKGROUND: Hydroxyethyl starch (HES) was part of "triple-H" therapy for prophylaxis and therapy of vasospasm in patients with subarachnoid haemorrhage (SAH). The European Medicines Agency restricted the use of HES in 2013 due to an increase of renal failure in critically ill patients receiving HES compared to crystalloid fluids. The occurrence of renal insufficiency in patients with SAH due to HES is still uncertain. The purpose of our study was to evaluate whether there was an association with renal impairment in patients receiving HES after subarachnoid haemorrhage...

Sepsis, a manifestation of the body's inflammatory response to injury and infection, has a mortality rate of between 28%-50% and affects approximately 1 million patients annually in the United States. Currently, there are no therapies targeting the cellular/molecular processes driving sepsis that have demonstrated the ability to control this disease process in the clinical setting. We propose that this is in great part due to the considerable heterogeneity of the clinical trajectories that constitute clinical "sepsis," and that determining how this system can be controlled back into a state of health requires the application of concepts drawn from the field of dynamical systems...

The basic reproduction number ([Formula: see text]) can be considerably higher in an SIR model with heterogeneous mixing compared to that from a corresponding model with homogeneous mixing. For example, in the case of measles, mumps and rubella in San Diego, CA, Glasser et al. (Lancet Infect Dis 16(5):599-605, 2016. https://doi.org/10.1016/S1473-3099(16)00004-9 ), reported an increase of 70% in [Formula: see text] when heterogeneity was accounted for. Meta-population models with simple heterogeneous mixing functions, e...

Background: Drug-induced hepatitis (DIH) occurs more commonly in tuberculous meningitis (TBM) than non-CNS tuberculosis. We evaluate DIH in TBM and its relationship with disease severity and surrogate markers of stress. Methods: Sixty-seven patients with TBM were included prospectively. The diagnosis of DIH was based on five times elevation of alanine amino transferase (ALT) in asymptomatic and three times in symptomatic patients, serum bilirubin 1.5 mg/dL or more occurring after 3 days of antitubercular drugs without any other cause of liver dysfunction; and improvement in liver function upon drug withdrawal...

Receptor interacting protein kinase 1 (RIPK1) plays a crucial role in tumor necrosis factor (TNF)-induced necroptosis, suggesting that this pathway might be druggable. Most inhibitors of RIPK1 are classified as either type II or type III kinase inhibitors. This opened up some interesting perspectives for the discovery of novel inhibitors that target the active site of RIPK1. Tozasertib, a type I pan-aurora kinase (AurK) inhibitor, was found to show a very high affinity for RIPK1. Since tozasertib presents the typical structural elements of a type I kinase inhibitor, the development of structural analogues of tozasertib is a good starting point for identifying novel type I RIPK1 inhibitors...

Background: Little is known regarding the optimal type of fluid resuscitation in acute pancreatitis (AP). Objective: The objective of this article was to compare the effect of lactated Ringer's solution (LR) vs normal saline (NS) in the inflammatory response in AP. Methods: We conducted a triple-blind, randomized, controlled trial. Patients ≥ 18 admitted with AP were eligible. Patients were randomized to receive LR or NS. Primary outcome variables were number of systemic inflammatory response syndrome (SIRS) criteria at 24 hours, 48 hours and 72 hours and blood C-reactive protein (CRP) levels at 48 hours and 72 hours...

Systemic inflammatory responses (SIRs) can help predict survival in various cancers. The present study investigated the accuracy of neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR) and prognostic nutritional index (PNI) in predicting survival for patients with recurrent cervical cancer. A retrospective review of prognoses examined the associations among NLR, PLR, and PNI, and clinical characteristics and survival in 79 patients with recurrent cervical cancer after undergoing concurrent chemoradiation therapy (CCRT) or radical hysterectomies with or without CCRT...

Laminitis, one of the most debilitating conditions of all equids, is now known to be the result of several systemic disease entities. This finding, together with other recent developments in the field of laminitis research, have provoked a rethink of our clinical and research strategies for this condition. First, laminitis is now considered to be a clinical syndrome associated with systemic disease (endocrine disease, sepsis or systemic inflammatory response syndrome, SIRS) or altered weight bearing rather than being a discrete disease entity...

Background/Aims: The relationship between intestinal Behçet's disease (BD) and cancer remains unclear. We conducted a nationwide, population-based study to determine the risk of cancer in patients with intestinal BD. Methods: Using the National Health Insurance claims records, we collected data on 365 patients who had been diagnosed with intestinal BD between 2011 and 2014. Standardized incidence ratios (SIRs) of overall and site-specific cancers in patients with intestinal BD in comparison with the general population were calculated...

Abdomino-scrotal hydrocele (ASH) is a very rare clinical entity. It is an unusual condition, in which there is an hourglass communication between a large hydrocele and the retroperitoneal space, through the inguinal canal. First described by Dupuytren in 1834 and defined by Bickle in 1919, the condition is rarely seen. Surgical management usually involves excision of the sac as the definitive treatment option. The pathogenesis of ASH remains unclear and numerous theories have been postulated. We favour the term scrotal-inguino-retroperitoneal (SIR) hydrocele as a more accurate description...

BACKGROUND: Severe acute pancreatitis (SAP) is characterised by two distinct clinical phases. Organ dysfunction and death is initially as a result of a systemic inflammatory response syndrome (SIRS). Systemic sepsis from infected pancreatic necrosis characterises the second phase, the so called 'second hit' of acute pancreatitis (AP). An immune imbalance during the second hit is postulated to contribute to the formation of the septic complications that occur in these patients. The pro-inflammatory T-helper (Th) 17 pathway has been shown to be an initiator of early SIRS in AP, however to date its role has not been established in the second hit in AP...

Systemic inflammatory response syndrome (SIRS) is an inflammatory state affecting the whole body. It is associated with the presence of pro- and anti-inflammatory cytokines in serum, including tumor necrosis factor (TNF). TNF has multiple effects and leads to cytokine production, leukocyte infiltration, blood pressure reduction and coagulation, thereby contributing to tissue damage and organ failure. A sterile mouse model of sepsis, TNF-induced SIRS, was used to visualize the temporal and spatial distribution of damage in susceptible tissues during SIRS...
