Thrombocytopenic patients requiring invasive surgery have few options to improve their platelet count preoperatively. This is a single-centre, retrospective review of thrombocytopenic patients receiving the thrombopoietin receptor agonist romiplostim perioperatively to allow for surgical interventions. Patient characteristics, romiplostim use, and surgical and safety outcomes (bleeding, thrombosis, transfusions) were collected and analysed. Forty-seven patients underwent 51 surgical procedures (ranging from total hip arthroplasty to open cardiac surgery) with romiplostim support...

Central venous (CV) catheterization is not only an invaluable diagnostic modality but also an essential therapeutic tool for the treating physician, enabling rapid and reliable intravenous administration of drugs and fluids, providing venous access to patients undergoing long-term continuous or repeated intravenous treatment such as chemotherapy or it can be used for haemodialysis in patients suffering from acute or chronic renal disease. On the other hand, CV catheterization can lead to a wide range of life-threatening complications for the patient especially if left untreated or become late-diagnosed...

Acute mesenteric ischemia is a rare life-threatening condition that accounts for approximately one in 1000 hospital admissions. The mortality rate is 50%-69% owing to the absence of specific symptoms and laboratory data, which makes early detection of this condition difficult. If the use of contrast material is possible, biphasic contrast material-enhanced multidetector computed tomography (CT) is the first-line imaging test for early diagnosis of the disease and for differentiation from other causes of acute abdomen...

BACKGROUND: Whereas chronic venous insufficiency and varicose veins (VVs) are a universally recognized problem, they are frequently underappreciated as major contributors to long-term morbidity in the elderly despite the increasing prevalence with age. Previous studies have demonstrated that chronic venous insufficiency and VV treatments in patients ≥65 years old yield an overall benefit; however, there have been few data as to whether octogenarians are undergoing these procedures and with what success...

BACKGROUND: Worldwide, at least 200 million people are affected by peripheral vascular diseases (PVDs), including peripheral arterial disease (PAD), chronic venous insufficiency (CVI) and deep vein thrombosis (DVT). The high prevalence and serious consequences of PVDs have led to the development of several diagnostic tools and clinical guidelines to assist timely diagnosis and patient management. Given the increasing number of diagnostic methods available, a comprehensive review of available technologies is timely in order to understand their limitations and direct future development effort...

Chemoreflex sensitization produced by chronic intermittent hypoxia (CIH) in rats is attenuated by angiotensin II type 1 receptor (AT1 R) blockade. AT1 R blockade and xanthine oxidase inhibition both ameliorate CIH-induced endothelial dysfunction. We hypothesized treatment with losartan and allopurinol would reduce chemoreflex sensitivity and improve hypoxic vasodilation in patients with obstructive sleep apnoea (OSA). Eighty-six hypertensive patients with apnoea-hypopnoea index ≥25 events/hr and no other cardiovascular, pulmonary, renal, or metabolic disease were randomly assigned to receive allopurinol, losartan, or placebo for 6 weeks...

BACKGROUND: Recent reports have demonstrated the adverse effects of venous congestion on renal function in patients with heart failure. None of these trials, however, has evaluated the effect of acute myocardial ischemia on the occurrence of acute kidney injury (AKI). METHODS: We conducted a retrospective study of 1336 ST segment elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PCI) between June 2012 and June 2016...

BACKGROUND: Primary aldosteronism (PA) is the most common cause of secondary hypertension and bilateral adrenal hyperplasia (BAH) and aldosterone-producing adenoma (APA) seem to be the most common causes of PA. Unilateral adrenalectomy (UA) is the preferred treatment for APA, although the benefits are still difficult to assess. CASE REPORT: We present a case report of a 69-year old man with a 30 year history of hypertension and probably long-standing PA due to APA, with typical organ complications...

INTRODUCTION: Several histologic features have been identified in the upper-extremity arteries and veins of patients with advanced chronic kidney disease, which may affect arteriovenous fistula maturation. However, it is unclear whether these chronic kidney disease vascular features are abnormal. METHODS: We obtained upper-extremity arterial and venous specimens from 125 advanced chronic kidney disease patients undergoing arteriovenous fistula creation and from 15 control subjects...

Background: Carbapenem-nonsusceptible Klebsiella pneumoniae (CnSKP) is rapidly emerging as a life-threatening nosocomial infection. The efficacy of tigecycline in the treatment of bloodstream infections (BSIs) remains controversial. Methods: Data from a total of 428 patients with carbapenem-susceptible Klebsiella pneumoniae (CSKP) and CnSKP BSIs were collected at a single center between January 2013 and December 2015. A three-part analysis was conducted to identify the risk factors associated with CnSKP, explore prognosis, and evaluate treatments...

OBJECTIVE: The middle hepatic vein reconstruction is one of the crucial parts in adult living donor liver transplantation. Numerous techniques had been reported by using cadaveric iliac vessel or synthetic graft. The limitations of reported techniques are availability of the vessel and complication of synthetic graft. We report the technique of using explanted portal vein and inferior mesenteric vein graft in sequential fashion. PATIENTS AND METHODS: The recipient was a 54-year-old man with chronic hepatitis B cirrhosis and multiple hepatocellular carcinomas...

BACKGROUND: Interleukin-6 (IL-6) production facilitates a shift from acute to chronic inflammation that may induce the development of some diseases and aging. Several studies have suggested that adiposity is closely related to serum IL-6 level, but their authors examined relatively young older adults (aged 60-80 years), so it is not clear whether this association would also occur in people at a more advanced age. OBJECTIVE: to assess whether in elderly women without inflammation the widely used anthropometric obesity indices are associated with serum IL-6 level and, if so, to determine the best anthropometric predictor of this inflammatory biomarker...

Chronic exposure of inorganic arsenic compounds is responsible for the manifestation of various tumours as well as other diseases. The principal mechanism behind arsenic toxicity is the induction of a strong oxidative stress with production of free radicals in cells. The present study was aimed to explore the shielding effect of anethole against oxidative damage induced by arsenic in cultured human peripheral blood lymphocytes and the effect of GSTO1 polymorphism. Sister chromatid exchange (SCE) frequency, comet tail moment and lipid peroxidation levels were used as biomarkers to assess the oxidative damage...

BACKGROUND: Fibroblast growth factor 23 (FGF-23), an osteocyte hormone involved in the regulation of phosphate metabolism, is associated with incident and progressive chronic kidney disease. We aimed to assess the association of FGF-23 with renal parameters, vascular function and phosphate metabolism in a large cohort of young and healthy individuals. METHODS: Healthy individuals aged 25-41 years were included in a prospective population-based study. Fasting venous blood and morning urinary samples were used to measure plasma creatinine, cystatin C, endothelin-1, phosphate and plasma FGF-23 as well as urinary creatinine and phosphate...

Venous thrombosis is a common condition affecting 1 - 2% of the population, with an annual incidence of 1 in 500. Venous thrombosis can lead to death through pulmonary embolism or results in the post-thrombotic syndrome, characterized by chronic leg pain, swelling, and ulceration, or in chronic pulmonary hypertension resulting in significant chronic respiratory compromise. This is the most common cardiovascular disease after myocardial infarction and ischemic stroke and is a clinical challenge for all medical disciplines, as it can complicate the course of other disorders such as cancer, systemic disease, surgery, and major trauma...

INTRODUCTION: Creating and maintaining a functional vascular access(VA) is a critical factor in the survival of a dialysis patient. However, it will not function forever, implying a creative attitude from the vascular surgeon either to maintain its functionality or built a new one wherever possible, being it autologous or synthetic. METHODS: Describe the VA history of a 59years-old male with morbid obesity and end-stage chronic kidney disease. RESULTS: His VA construction started in2012 with failed attempts in both forearms until a functional brachiocephalic artery-venous fistula(AVF) in the right upper limb was achieved, but was deemed to ligation as severe venous hypertension secondary to central venous disease related to CVC use...
