Objective: To analyze the cumulative effect of risk factors associated with early major complications in postoperative spine surgery. Methods: Retrospective analysis of 583 surgically-treated patients. Early "major" complications were defined as those that may lead to permanent detrimental effects or require further significant intervention. A balanced risk score was built using multiple logistic regression. Results: Ninety-two early major complications occurred in 76 patients (13%)...

Alcoholic hepatitis (AH) is the most severe form of alcoholic liver disease for which there are no effective therapies. Patients with AH show impaired hepatocyte proliferation, expansion of inefficient ductular cells and high lipopolysaccharide (LPS) levels. It is unknown whether LPS mediates ductular cell expansion. We performed transcriptome studies and identified keratin 23 (KRT23) as a new ductular cell marker. KRT23 expression correlated with mortality and LPS serum levels. LPS-TLR4 pathway role in ductular cell expansion was assessed in human and mouse progenitor cells, liver slices and liver injured TLR4 KO mice...

Myc is an essential regulator of cell growth and proliferation. Myc overexpression promotes the homeostatic expansion of cardiomyocyte populations by cell competition, however whether this applies to other cardiac lineages remains unknown. The epicardium contributes signals and cells to the developing and adult injured heart and exploring strategies for modulating its activity is of great interest. Using inducible genetic mosaics, we overexpressed Myc in the epicardium and determined the differential expansion of Myc-overexpressing cells with respect to their wild type counterparts...

BACKGROUND: Obesity is commonly investigated as a potential risk factor for LBP, however the current evidence remains unclear. Limitations in previous studies may explain the inconsistent results in the field such as use of a cross-sectional design, limitations in the measures used to assess obesity (e.g. body mass index - BMI) and poor adjustment for confounders (e.g. genetics and physical activity). PURPOSE AND DESIGN: To better understand the effects of obesity on LBP, our aim was to investigate in a prospective cohort whether obesity-related measures increase the risk of chronic LBP outcomes using a longitudinal design...

OBJECTIVE: To describe attitudes towards patient safety culture among workers in a hospital setting and determine the influence of socio-demographic and professional variables. METHODS: The Hospital Survey on Patient Safety Culture was distributed among a sample of professionals and nursing assistants. A dimension was considered a strength if positive responses exceeded 75% and an opportunity for improvement if more than 50% of responses were negative. RESULTS: 59% (n=123) of respondents rated safety between 7 and 8...

The stable isotope signatures of zinc are increasingly used to study plant and soil processes. Complexation with phytosiderophores is a key process and understanding the controls of isotope fractionation is central to such studies. Here, we investigated isotope fractionation during complexation of Zn2+ with the phytosiderophore 2'-deoxymugeneic acid (DMA) - which we synthesised - and with three commercially-available structural analogues of DMA: EDTA, TmDTA and CyDTA. We used ion exchange chromatography to separate free and complexed zinc, and identified appropriate cation exchange resins for the individual systems...

STUDY OBJECTIVE: The presence of obstructive sleep apnea (OSA) in patients with cancer appears to be accompanied by poorer outcomes. However, the mechanisms underlying such association are unknown. Tumor infiltrating lymphocytes (TILs), including CD8+ T cells, function as cytotoxic T lymphocytes (CTLs), and mount immune responses to cancer by the release of cytolytic enzymes, including granzyme B (GzmB), perforin (Prf) and cytokines such as interferon (IFN)-γ. METHODS: Using established in vivo mouse models, we investigated CD8+ T cells and cancer stem cells (CSC) in intermittent hypoxia (IH) and sleep fragmentation (SF) in the context of tumor environment...

BACKGROUND: Hip arthroscopy is considered a safe procedure, considering the relatively low rate of complications. Despite several complications have been described following this surgical procedure, the present event has not yet been described. The purpose of the present study is to report an unpublished complication following hip arthroscopy, after reviewing 162 hip arthroscopies and finding iliotibial band syndrome (ITBS) in the knee during followup. MATERIALS AND METHODS: A retrospective review of 162 hip arthroscopies performed between September 2007 and June 2011 was carried out, evaluating patients who presented ITBS during followup...

INTRODUCTION: Older persons aged over 65years represent up to 41% of Australian Emergency Department (ED) presentations. Older persons present with acute and/or chronic conditions, have more Emergency Department visits, hospital admissions and readmissions than other age groups. However, little is known about the characteristics and trends of acute illness and chronic presentations and whether frailty changes these dimensions within this cohort. METHODS: A 12-month retrospective medical record audit of persons over 65years presenting to four EDs...

OBJECTIVE: We investigated whether successful revascularization of total occlusion of a large lower-extremity artery is associated with improvement of left ventricular (LV) diastolic function. BACKGROUND: Total occlusion of a large lower-extremity artery might affect the systemic vascular resistance and increase the afterload, because the left ventricle must work harder to eject blood into a smaller vascular bed. Chronic elevation of afterload is a cause of LV diastolic dysfunction...
