BACKGROUND: Apoptosis of human umbilical vein endothelial cells (HUVECs) plays an important role in the progression of Henoch-Schonlein purpura (HSP). In the present study, we explored the function of miR-218-5p in HUVEC apoptosis and HSP development. MATERIALS AND METHODS: HSP rat model was established and peripheral blood mononuclear cells (PBMC) were isolated. The expression of miR-218-5p and high-mobility group box-1 (HMGB1) protein in HUVECs was determined by quantitative real-time polymerase chain reaction and western blot, respectively...

BACKGROUND: Only a subset of patients with excessive alcohol use develop alcoholic liver disease (ALD), though the exact mechanism is not completely understood. Once ingested, alcohol is metabolized by 2 key oxidative enzymes, alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH). There are 2 major ALDH isoforms, cytosolic and mitochondrial, encoded by the aldehyde ALDH1 and ALDH2 genes, respectively. The ALDH2 gene was hypothesized to alter genetic susceptibility to alcohol dependence and alcohol-induced liver diseases...

Postthrombotic syndrome is a common long-term complication of proximal lower extremity deep venous thrombosis, which not only significantly affects the quality of life of patients but also imposes a substantial financial burden on our healthcare system. Due to limited awareness and inability of physicians to recognize and treat this condition early, its prevalence is steadily increasing. In this article, we review the pathophysiology, the risk factors involved, diagnostic workup, and the various management options available to treat this condition...

This single-center, retrospective review identified 6 patients (n = 6, 100% female) treated by endovascular therapy for May-Thurner syndrome from June 2013 to September 2015. Patients consisted of 3 African American, 2 Caucasian and 1 Asian; mean age was 53.50 ± 8.31 years, range: 39-63 years. Clinical presentations consisted of left lower extremity deep vein thrombosis in 4, left lower extremity deep vein thrombosis with pulmonary embolism in 1 and pulmonary embolism with left common iliac vein thrombosis in 1 patient...

Denosumab is a monoclonal antibody directed against the receptor activator of nuclear factor kappa B ligand (RANKL). Denosumab has been shown to reduce the risk of skeletal-related events, including spinal cord compression, pathologic fracture and hypercalcemia of malignancy in patients with bone metastases. Hypocalcemia is a known side effect of denosumab, occurring in an estimated 8-14% of the patients. Here, we present an asymptomatic patient with stage-5 chronic kidney disease and severe hypocalcemia who had received denosumab 1 month earlier...

BACKGROUND: Alcohol significantly impairs antioxidant defenses and innate immune function in the lung and increases matrix metalloproteinase 9 (MMP-9) activity. The receptor for advanced glycation end products (RAGE) is a well-characterized marker of lung injury that is cleaved by MMP-9 into soluble RAGE and has not yet been examined in the alcoholic lung. We hypothesized that chronic alcohol ingestion would impair RAGE signaling via MMP-9 in the alveolar macrophage and thereby impair innate immune function...

BACKGROUND: Successful treatment of leukemia requires new medications to combat drug resistance, but the development of novel therapies is an arduous and risky endeavor. Repurposing currently approved drugs or those already in clinical development to treat other indications is a more practical approach. Moreover, combinatorial therapeutics are often more efficacious than single agent therapeutics because the former can simultaneously target multiple pathways that mitigate tumor aggressiveness and induce cancer cell death...

BACKGROUND: This study aimed to investigate the expression levels and relationship of bone morphogenetic proteins (BMPs) signaling molecules and microRNA-140 (miR-140) in human osteoarthritis (OA) chondrocytes. MATERIALS AND METHODS: Different stage chondrocytes (normal cartilage, mid-stage OA and advanced-stage OA) were isolated from cartilage samples according to Kellgren and Lawrence criteria. The effect of miR-140 on BMPs signaling was evaluated by transfecting miR-140 mimic or inhibitor into chondrocytes...

Atrial fibrillation (AF) is associated with high risk of systemic thromboembolism leading to significant morbidity and mortality. Warfarin, previously the mainstay for stroke prevention in AF, requires close monitoring because of multiple food and drug interactions. In recent years, food and drug administration has approved several direct oral anticoagulants (DOACs) for use in patients with nonvalvular AF. These agents have not been studied in patients with valvular AF who are at an even higher risk of systemic thromboembolism...

BACKGROUND: Egypt is one of the largest epidemic areas of hepatitis C virus (HCV) in the world. Its prevalent genotype is 4 with a majority of subtype 4a. In 2013, the Food and Drug Administration approved a new direct-acting antiviral drug (sofosbuvir) to treat patients with chronic HCV infection. In Egypt, the patients are already being treated with sofosbuvir in conjunction with ribavirin and pegylated interferon alfa-2a (PEG-IFNα-2a) for 12 weeks since 2015. The present study was planned to explain the efficacy of this treatment regimen against the HCV genotype 4a in Egyptian patients and its pretreatment predictive factors of virological response...

BACKGROUND: Oxidative stress occuring in patients diagnosed with inflammatory bowel disease (IBD), but the relationship between oxidative stress, disease activity and inflammatory markers has not been well established. MATERIALS AND METHODS: A total of 30 patients diagnosed with IBD and 30 volunteers who had normal colonoscopies, selected as controls, were used for this study. The serum levels of antioxidant enzymes (catalase and glutathione peroxidase) and oxidative markers (malondialdehyde [MDA] and total antioxidant capacity) were compared between the 2 groups...

BACKGROUND: This study was designed to comparatively assess the effects of add-on pentoxifylline to losartan versus increasing the dose of losartan on serum N-terminal pro-brain natriuretic peptide (NT-proBNP), serum highly sensitive C-reactive protein (hsCRP) and the urinary albumin excretion (UAE) rate in patients with type 2 diabetes and nephropathy. METHODS: In an open-label, single-center, parallel-group, randomized clinical trial (NCT03006952), 30 patients received b...

Chun-Wu Tung, Yung-Chien Hsu, Ya-Hsueh Shih, Pey-Jium Chang, Chun-Liang Lin
BACKGROUND: Osteoporosis is associated with a poor quality of life and mortality. Proteinuria contributes to vitamin D deficiency and osteoblast dysfunction. The correlation between estimated glomerular filtration rate (eGFR) and bone density still remains elusive. Therefore, we sought to investigate whether reduced eGFR or proteinuria are independently associated with the osteoporotic risk. METHODS: We conducted a cross-sectional study using community-based health survey data from January 2004 to December 2008 in southern Taiwan...

Çağdaş Kalkan, Irfan Soykan
BACKGROUND: Gastric emptying (GE) of solids is delayed and autonomic dysfunction is detected in autoimmune gastritis (AIG). The goals of this study were to: (1) compare serum levels of ghrelin and motilin in subjects with delayed and normal GE and (2) investigate whether circulating antimyenteric antibodies (CAA), serum ghrelin levels and motilin levels have any effect on autonomic function. MATERIALS AND METHODS: Noninvasive cardiovascular reflex tests were used in order to evaluate the autonomic function...

BACKGROUND: Epidemiologic studies suggest reduced cardiovascular disease (CVD) events with moderate alcohol consumption. However, heavy and binge drinking may be associated with higher CVD risk. Utilizing the Nationwide Inpatient Sample, we studied the association between a troublesome alcohol history (TAH), defined as those with diagnoses of both chronic alcohol syndrome and acute withdrawal history and CVD events. METHODS: Patients >18 years with diagnoses of both chronic alcohol syndrome and acute withdrawal using the International Classification of Diseases-Ninth Edition-Clinical Modification (ICD-9-CM) codes 303...

BACKGROUND: There is a lack of research on the effect of low dose of angiotensin receptor blockers combined with spironolactone, and the effect of high dose of angiotensin receptor blockers alone on the urinary albumin excretion rate (UAER) in elderly patients with early type 2 diabetic nephropathy (DN). METHODS: We conducted a prospective, randomized, open-label, parallel-controlled study that included 244 elderly patients with early DN and mild-to-moderate essential hypertension...
