BACKGROUND: The serum level of osteoprotegerin (encoded by OPG or TNFRSF11B) was previously shown to be increased in patients with ischemic stroke. A single nucleotide polymorphism rs3134069 in the TNFRSF11B gene was previously associated with ischemic stroke in a population of diabetic patients in Italy. It remains to be determined whether rs3134069 is associated with ischemic stroke in the general population or populations without diabetes. MATERIALS AND METHODS: We genotyped rs3134069 and performed a case-control association study to test whether rs3134069 is associated with ischemic stroke in 2 independent Chinese Han populations, including a China-Central population with 1629 cases and 1504 controls and a China-Northern population with 1206 cases and 720 controls...

Echocardiography has contributed to the care of critically ill patients but there remains a need for more publications about its association with outcomes to confirm its role. We conducted a retrospective review of trauma and burn patients that were admitted to our intensive care unit between 2015 and 2017 that underwent hemodynamic transesophageal echocardiography. Data collected included demographics, clinical and laboratory data. Right ventricle fractional area of change (RVFAC) measurements were performed on still mages obtained from mid-esophageal four-chamber-view clips...

BACKGROUND: Little data is available in the literature about the role of end tidal oxygen in critically ill patients. We sought to identify the association between the level of respiratory oxygen and clinical outcomes in critically-ill ventilated trauma and burn patients. METHODS: A retrospective cohort of 55 trauma and burn patients from 2010 to 2016 was collected. Exposures of interest included a) expiratory end tidal oxygen (ETO2) and b) the difference between FiO2 and ETO2 (uptake)...

BACKGROUND: The Centers for Disease Control and Prevention (CDC) replaced its definition for ventilator-associated pneumonia (VAP) in 2013. The aim of the current study is to compare the outcome of burn patients with ventilator associated events (VAEs). METHODS: Burn patients with at least two days of ventilator support were identified from the registry between 2013 and 2016. Kruskal-Wallis and Fisher's exact tests were utilized for continuous and categorical variables, respectively...

BACKGROUND: Conventional echocardiographic technique for assessment of volume status and cardiac contractility utilizes left ventricular end-diastolic area (LVEDA) and fractional area of change (FAC), respectively. Our goal was to find a technically reliable yet faster technique to evaluate volume status and contractility by measuring left ventricular end-diastolic diameter (LVEDD) and fractional shortening (FS) in a cohort of mechanically ventilated trauma and burn patients using hemodynamic transesophageal echocardiographic (hTEE) monitoring...

The tissue factor pathway inhibitor (TFPI) gene encodes a protease inhibitor with a critical role in regulation of blood coagulation. Some genomic variants in TFPI were previously associated with plasma TFPI levels, however, it remains to be further determined whether TFPI variants are associated with other coagulation factors. In this study, we carried out a large population-based study with 2313 study subjects for blood coagulation data, including fibrinogen levels, prothrombin time (PT), activated partial thromboplastin time (APTT), and thrombin time (TT)...

BACKGROUND: The Centers for Disease Control and Prevention's National Healthcare Safety Network (NHSN) replaced its old definition for ventilator-associated pneumonia (VAP) with the ventilator-associated events algorithm in 2013. We sought to compare the outcome of trauma patients meeting the definitions for VAP in the two modules. METHODS: Trauma patients with blunt or penetrating injuries and with at least 2 d of ventilator support were identified from the trauma registry from 2013 to 2014...

OBJECTIVES: The National Healthcare Safety Network (NHSN) replaced its old definition for ventilator-associated pneumonia (VAP) with ventilator-associated events (VAEs) in 2013. Little data is available comparing the two definitions in burn patients. METHODS: Data from 2011 to 2014 were collected on burn patients mechanically ventilated for at least 2 days. VAP was determined using two methods: (1) pneumonia as defined by the previous more clinical CDC (NHSN) definition captured in the burn registry; (2) pneumonia as defined by the recent CDC (NHSN) standard of VAEs where patients meeting the criteria for possible VAP were considered having a pneumonia...

BACKGROUND: The role of echocardiographic indices of preload and contractility in predicting outcomes is unknown. We report the association of end diastolic area (EDA) and fractional area of change (FAC) with mortality in a cohort of trauma and burn patients. METHODS: Data on 86 patients admitted to a tertiary care center between July 2013 and July 2015 were reviewed. The association between abnormal EDA and FAC and adverse clinical outcomes was tested using exact logistic regression analysis...

The interleukin 1 family plays an important role in the immune and inflammatory responses. Coronary artery disease (CAD) is a chronic inflammatory disease. However, the genetic association between IL-37, the seventh member of the IL-1 family, and CAD is unknown. Here we show that a single nucleotide polymorphism in the IL-37 gene (rs3811047) confers a significant risk of CAD. We have performed an association analysis between rs3811047 and CAD in two independent populations with 2,501 patients and 3,116 controls from China...

OBJECTIVE: Coagulopathy is known to be associated with burn injury. Our group has shown that, in spinal cord injury patients, coagulopathy is associated with an increase in ventilator-associated pneumonia (VAP). We hypothesized that the same association exists between coagulopathic burn patients and ventilator-associated events. METHODS: Patients admitted for burn care between January 1, 2011 and December 31, 2015 who required mechanical ventilation were included in the study...

INTRODUCTION: Early trauma-induced coagulopathy may increase susceptibility to nosocomial infections such as ventilator-associated pneumonia. However, the relationship between trauma- induced coagulopathy and the development of ventilator-associated pneumonia in spinal cord injury patients has not been evaluated. METHODS: We conducted a 5-year retrospective study of 300 spinal cord injury patients admitted to Level 1 trauma center. Standard coagulation studies were evaluated upon arrival, prior to fluid resuscitative efforts, and at 24  h after admission...

BACKGROUND: A survival advantage has been observed among patients with malignant pleural mesothelioma undergoing maximal cytoreductive surgery and adjuvant therapy. Elderly patients are considered higher risk for these radical operations and are commonly not offered surgical treatment. We reviewed our experience with extended pleurectomy and decortication among patients 70 years or older and compared them with a cohort of younger patients undergoing extended pleurectomy and decortication for malignant pleural mesothelioma...

BACKGROUND: Maximal cytoreductive surgeries--extrapleural pneumonectomy and extended pleurectomy and decortication (EPD)--are effective surgical treatments in selected patients with malignant pleural mesothelioma. Extended pleurectomy and decortication results in equivalent survival yet better health-related quality of life (HRQoL). METHODS: Patients with malignant pleural mesothelioma were studied for the effects of EPD on HRQoL and pulmonary function. The European Organization for Research and Treatment of Cancer Core Quality of Life Questionaire-C30 was used to evaluate HRQoL before operation, and at 4 to 5 and 7 to 8 months postoperatively...

OBJECT: Extracranial cerebrovascular injury is believed to be an important cause of neurological injury in patients who have suffered blunt trauma. The authors sought to determine the timing and mechanisms of ischemic stroke in patients who suffered traumatic cerebrovascular injury (TCVI). METHODS: This is a prospective study of all patients with TCVI who were admitted to a Level I trauma center during a 28-month period. All patients who suffered blunt trauma and had risk factors for TCVI underwent screening CT angiography (CTA) of the head and neck on admission...

A 46-year-old patient supported by a biventricular assist device (BiVAD) was transferred to our institution for evaluation for heart transplant. The patient was found to have a large intracranial hemorrhage with profound deterioration of neurologic status. The poor prognosis prompted the decision to withdraw care and pursue organ donation. Because the patient did not meet brain death criteria, nonheart-beating donor organ donation was pursued. After the termination of care, the BiVAD was modified: the left side to provide organ preservative solution and the right side to allow drainage...
