BACKGROUND: Platelet cells, or thrombocytes, have additional roles to haemostasis. After burn injury, platelet counts drop to a nadir at days 2-5 then rise to a peak between days 10-18. The nadir has previously been associated with mortality but there is currently no thorough investigation of its potential to predict sepsis in adults. The primary objective of this study is to assess whether platelet count can predict survival and sepsis in adults with severe burn injuries. METHODS AND FINDINGS: A retrospective cohort analysis of platelet count and other blood parameters in 145 burn patients with a TBSA greater than 20%...

BACKGROUND: Patients with intra-abdominal infections need to achieve adequate hemodynamic status before being taken to the operating room. Multiple parameters (urinary output [UOP], vital signs, inferior vena cava collapsibility index, and central venous pressure) may be used to assess hemodynamic response to fluid resuscitation, but the options are few in limited-resource settings. This study aimed at assessing if a bedside-performed ultrasound to assess the inferior vena cava collapsibility index is superior to UOP in assessing hemodynamic response to fluid resuscitation...

BACKGROUND: During sepsis, optimal plasma antibiotic concentrations are mandatory. Modifications of pharmacokinetic parameters could lead to low drug concentrations and therefore, insufficient therapeutic levels. OBJECTIVE: The aim of this study was to build a population pharmacokinetic model for cefotaxime and its metabolite desacetylcefotaxime in order to optimize individual dosing regimens for critically ill children. METHODS: All children aged < 18 years, weighing more than 2...

BACKGROUND: Renal toxicity induced by cisplatin (CisPt) is a clinical issue in patients with or without chronic kidney disease (CKD). Proximal tubular injury can result in acute kidney injury (AKI), which may compromise the course of chemotherapy and the prognosis. The purpose of this study was to investigate the time course of urinary markers of acute tubulotoxicity and to assess the usefulness of such monitoring in a routine clinical setting. METHODS: This work is an open prospective pilot study carried out among 23 patients receiving a platinum-based chemotherapy...

Sepsis is a severe disease with a high mortality index and it is responsible for the development of acute lung injury (ALI). We evaluated the effects of light-emitting diode (LED) on ALI induced by sepsis. Balb-c mice were injected with lipopolysaccharide or saline and then irradiated or not with red LED on their tracheas and lungs for 150 s, 2 and 6 h after LPS injections. The parameters were investigated 24 h after the LPS injections. Red LED treatment reduced neutrophil influx and the levels of interleukins 1β, 17 A and, tumor necrosis factor-α; in addition to enhanced levels of interferon γ in the bronchoalveolar fluid...

Bacterial infections often cause fatal systemic infections in patients with primary immunodeficiency. To prevent unfortunate results, the selection, dose, and dosage of antibiotics are extremely important. Here, we report a case of Wiskott-Aldrich syndrome in a patient undergoing peritoneal dialysis because of chronic renal failure in whom methicillin-resistant Staphylococcus aureus sepsis developed. Because of the primary disease and complications, teicoplanin was the only chosen anti-S. aureus drug to prevent side effects...

INTRODUCTION: Quantification of surgical sepsis was never done beyond superficial, subfascial, and deep surgical site infection (SSI). Invasive surgical sepsis with systemic manifestation has not been tried to be quantified in general and pediatric surgery in particular. Hence, this attempts to develop a novel grading system to quantify neonatal surgical infections. MATERIALS AND METHODS: Predisposing factors, infection, response, and organ failure (PIRO) is being used in critical care institutions for medical sepsis; it was modified with neonate-specific surgical parameters...

OBJECTIVE: Recent clinical studies have shown that anticoagulant therapy might be effective only in specific at-risk subgroups of patients with sepsis and coagulation dysfunction. The definition of sepsis was recently modified, and as such, old scoring systems may no longer be appropriate for the diagnosis of sepsis-associated coagulopathy. The aim of this study was to evaluate prognostic factors in patients diagnosed with sepsis and coagulopathy according to the new sepsis definition and assess their accuracy in comparison with existing models...

Mitochondrial aldehyde dehydrogenase 2 (ALDH2) is closely associated with organ injury. The aim of the present study was to investigate the change of ALDH2 expression in a rat model of sepsis-induced acute renal injury, and to observe the effect of ALDH2 inhibition on the kidney. A model of sepsis syndrome was established in Sprague-Dawley (SD) rats by cecal ligation and puncture (CLP). The rats were divided into sham, CLP and CLP + cyanamide (CYA, an ALDH2 inhibitor) groups. The hemodynamic parameters heart rate (HR) and mean arterial blood pressure (MABP) were measured...

We develop and study an innovative method for jointly modeling longitudinal response and time-to-event data with a covariate subject to a limit of detection. The joint model assumes a latent process based on random effects to describe the association between longitudinal and time-to-event data. We study the role of the association parameter on the regression parameters estimators. We model the longitudinal and survival outcomes using linear mixed-effects and Weibull frailty models, respectively. Because of the limit of detection, missing covariate (explanatory variable, x) values may lead to the non-ignorable missing, resulting in biased parameter estimates with poor coverage probabilities of the confidence interval...

OBJECTIVE: To compare different support therapies in very low birth-weight preterm neonates with nosocomial sepsis. METHODS: This clinical pilot study was conducted at the Bagcilar Research and Training Hospital, Istanbul, Turkey, from September 2015 to November 2016. Preterm infants appropriately sized for a gestational age of < 32 weeks and < 1,500g were included in the study. Pentaglobin was initiated on the day of diagnosis of nosocomial sepsis to very low birth-weight preterm neonates as a support therapy in addition to antibiotics: 5 ml/kg per day of pentaglobin was infused over a four-hour period on three consecutive days...

Precise assessment of left ventricular (LV) contractility during veno-arterial extracorporeal membrane oxygenation (VA-ECMO) support is crucial. However, changes in loading conditions may mask changes in LV function when assessed with load-dependent parameters. We compared end-systolic elastance (Ees, mm Hg/ml), the reference load-independent parameter of LV contractility, with LV ejection fraction (LVEF) in two patients. The first patient was a 54-year-old patient supported with femoro-femoral VA-ECMO for a cardiogenic shock...

BACKGROUND: β-lactams are among the most frequently prescribed antibiotics for the treatment of neonatal sepsis. Survival of extremely preterm neonates necessitates an improved understanding of how β-lactams should be used in this vulnerable population. Appropriate dosing regimens for neonates remain unclear. We reviewed available data on the pharmacokinetics (PK) of β-lactam drugs in neonates. Pharmacokinetic/pharmacodynamic (PK/PD) efficacy index surrogates and minimum inhibitory concentrations (MICs) used to support dosing regimens recommendation in the studies were also investigated...

Prolongation of prothrombin time (PT) is often encountered in patients with sepsis. On the other hand, thromboelastometry as a global coagulation test might yield normal results. The aim of our study was to evaluate whether prolonged PT in the presence of normal thromboelastometry parameters is associated with severe bleeding in patients with sepsis undergoing invasive procedures. In patients with sepsis undergoing low-risk bleeding invasive procedures (central venous catheter placement, dialysis catheter insertion, drain insertion, and so on) or high-risk bleeding invasive procedures (surgical tracheostomy, surgical laparotomy, thoracotomy, and so on), coagulation was assessed by thromboelastometry using EXTEM test (test for evaluation of the extrinsic pathway of coagulation, contains activator of extrinsic pathway) and with PT...

Melioidosis, caused by Burkholderia pseudomallei, is a potentially lethal infection with no licensed vaccine. There is little understanding of why some exposed individuals have no symptoms, while others rapidly progress to sepsis and death, or why diabetes confers increased susceptibility. We prospectively recruited a cohort of 183 acute melioidosis patients and 21 control subjects from Northeast Thailand and studied immune parameters in the context of survival status and the presence or absence of diabetes...
