Background: Individuals with HIV have ∼2-fold increased risk of developing pulmonary fibrosis. The mechanism(s) by which this occurs has yet to be determined. HIV-1 protein gp120 activates CXCR4 in the lymphocyte, promoting a variety of intracellular signaling pathways including those common to TGFβ1 associated with lung fibroblast-to-myofibroblast transdifferentiation.

Background: The Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score is an anatomic scoring system based on coronary angiography that quantifies lesion severity and complexity and predicts morbidity and mortality to guide decision making between coronary artery bypass graft surgery and percutaneous coronary intervention in patients with acute coronary syndrome. The present study aimed to compare nitric oxide levels with the SYNTAX score in terms of predicting coronary complexity and the treatment decision for unstable angina pectoris in the emergency department.

Methods: The study included 120 patients with unstable angina pectoris and 120 control group subjects. Read More

Background: Since aortic valve sclerosis (AVS) and coronary artery disease (CAD) share similar cardiovascular risk factors, we hypothesized that the clinical profile of patients with acute myocardial infarction (AMI) would be worse in the presence of AVS. The aim of this study was to investigate the association between AVS and clinical factors in patients with AMI.

Methods: Three hundred and fifteen patients with AMI were consecutively enrolled in the study. Read More

Background: Systemic lupus erythematosus (SLE) patients often exhibit hematological abnormalities, but the role of thrombocytopenia on the prognosis of SLE shows inconsistent results. The purpose of this meta-analysis was to confirm the impact of thrombocytopenia on mortality and end organ damage in patients with SLE.

Materials And Methods: Three electronic databases, PubMed, Embase and Cochrane library were systematically searched to identify the eligible studies from inception to November 2017 in order to evaluate the impact of thrombocytopenia on the prognosis of patients with SLE. Read More

An anuric woman with ascites rapidly developed extreme hyperglycemia and seizures after hemodialysis. During development of hyperglycemia, the decrease in serum sodium concentration (Δ[Na]) was nearly twice the value predicted by a formula accounting for the degree of hyperglycemia and the intracellular-to-extracellular volume ratio. The prediction assumed that ascitic fluid is part of the extracellular volume. Read More

Pulmonary fibrosis refers to a heterogeneous group of disorders that scar the lung, most often irreversibly. To date, there are limited effective treatments for these conditions, despite decades of research in this area of investigation. In pulmonary fibrosis, the principle cell responsible for producing the vast majority of scar tissue is the fibroblast, making these cells ideally suited for drug targeting. Read More

Immobilized orthopedic trauma patients face an elevated risk of venous thromboembolism (VTE). We present a case in which a patient undergoing staged repair of traumatic orthopedic injuries developed deep venous thrombosis (DVT) during hospitalization, prior to repair of a lower extremity injury for which delay in operation might result in poor functional outcome. We provide an overview of recommendations regarding pharmacologic prophylaxis of VTE in orthopedic patients. Read More

Irvine Page in the United States and Eduardo Braun-Menéndez in Argentina led teams of investigators that studied the role of the kidney in blood pressure regulation. Contemporaneously in 1939, each team using different methods discovered and described a new substance now known as angiotensin.

Phagocytosis is necessary for antigen degradation and presentation, the activation of the adaptive immune response and the elimination of pathogenic micro-organisms. The phagosomal vacuole formed during phagocytosis requires a process of maturation that involves fusion with lysosomes, a decrease in luminal pH and the activation of the enzymes that eventually will destroy phagocytized micro-organisms. Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis. Read More

Francisco Goya produced over 1,800 works during his long career, which earned him a reputation as one of the greatest artists of modern times. When he was 47, he developed a mysterious illness that destroyed his hearing, and for the next 35 years left him "deaf as a stump." Of the diagnoses proposed to date, Susac syndrome is the one most consistent with what little we do know of the character of that illness. Read More

In this review, we discuss the pathologic mechanism of the angiogenesis process in osteosarcoma (OS) and the therapeutic use of angiogenesis inhibitors in OS treatment. The activation of endothelial cells by angiogenic factors leads to the production of proteolytic enzymes, which degrade the extracellular matrix. The degradation of the underlying basement membrane enables endothelial cells to proliferate and migrate to the surrounding tissue to form new vessels. Read More

Implantable cardioverter-defibrillators (ICDs) monitor for and terminate malignant arrhythmias. Given their potential as a life-saving therapy, an increasing number of people receive an ICD every year, and a growing number are currently living with ICDs. However, cardiopulmonary arrest serves as the final common pathway of natural death, and the appropriate management of an ICD near the end-of-life is crucial to ensure that a patient's death is not marked by further suffering due to ICD shocks.
