Turnover concepts in state-of-the-art global vegetation models (GVMs) account for various processes, but are often highly simplified and may not include an adequate representation of the dominant processes that shape vegetation carbon turnover rates in real forest ecosystems at a large spatial scale. Here we evaluate vegetation carbon turnover processes in GVMs participating in the Inter-Sectoral Impact Model Intercomparison Project (ISI-MIP; including HYBRID4, JeDi, JULES, LPJml, ORCHIDEE, SDGVM, and VISIT) using estimates of vegetation carbon turnover rate (k) derived from a combination of remote sensing based products of biomass and net primary production (NPP)...

Inferior vena cava (IVC) thrombosis is a rare complication of abdominal aortic aneurysm (AAA). A 70-year-old male patient of Italian origin presented with a 9.3 x 8.4 cm infrarenal AAA, which was treated by endovascular aortic repair (EVAR). He reported a history of ulcerative colitis and was on prednisolone 80 mg daily. Seven weeks postoperatively the patient was readmitted with a deep vein thrombosis including both iliac veins and IVC, and bilateral pulmonary embolism. Venous thrombectomy and decompression of the IVC was performed by partial resection of the aneurysm sac...

The management of venous compression syndromes has historically been reliant on surgical treatment when conservative measures fail. There are, however, several settings in which endovascular therapy can play a significant role as an adjunct or even a replacement to more invasive surgical methods. We explore the role of minimally invasive treatment options for three of the most well-studied venous compression syndromes. The clinical aspects and pathophysiology of Paget-Schroetter syndrome (PSS), nutcracker syndrome, and May-Thurner syndrome are discussed in detail, with particular emphasis on the role that interventionalists can play in minimally invasive treatment...

Venous compression syndromes are a unique group of disorders characterized by anatomical extrinsic venous compression, typically in young and otherwise healthy individuals. While uncommon, they may cause serious complications including pain, swelling, deep venous thrombosis (DVT), pulmonary embolism, and post-thrombotic syndrome. The major disease entities are May-Thurner syndrome (MTS), variant iliac vein compression syndrome (IVCS), venous thoracic outlet syndrome (VTOS)/Paget-Schroetter syndrome, nutcracker syndrome (NCS), and popliteal venous compression (PVC)...

BACKGROUND: Intravascular ultrasound (IVUS) allows intraluminal imaging of blood vessels rather than the one-dimensional luminal outline depicted by digital subtraction angiography (DSA). Despite extensive literature in multiple adult vascular diseases, IVUS has not been directly compared to DSA in pediatric and adolescent vascular pathologies. OBJECTIVE: The purpose of this manuscript is to compare absolute luminal diameter measurements obtained via IVUS and DSA during a variety of pediatric endovascular procedures...

Modern, minimally invasive techniques used to treat deep venous thrombosis, such as percutaneous mechanical thrombectomy (PMT) and catheter-directed thrombolysis, have gained worldwide acceptance. PMT has the advantage of speed and is also associated with improved outcomes, shortened hospital stays, and low complication rates. The main complications associated with PMT have been primarily due to iatrogenic vascular damage resulting in perforation, embolic occlusion, and arteriovenous fistula formation; to date, there has been no publication in the literature describing complications resulting from device failure...

Since progranulin (PGRN) is a natural ligand of TNF receptors, we assessed whether serum PGRN levels predict and/or reflect responsiveness of RA patients to TNF-antagonist therapy. TNF-antagonist-naïve RA patients (N = 35) were started on TNF-antagonist therapy. At baseline and at follow-up visits, DAS28-ESR, DAS28-CRP, and CDAI were calculated, and venous blood was collected for serum PGRN determination. Disease activity and clinical response were based on EULAR criteria. Baseline serum PGRN levels varied considerably and correlated with ESR and CRP...

PURPOSE: To report a single-center experience in regard to the technique, safety, and clinical outcomes of endovascular therapy for treatment of May-Thurner syndrome (MTS) in adolescent patients. MATERIALS AND METHODS: A retrospective review identified 10 patients (6 female; mean age, 16 y; range, 12-18 y; mean weight, 73 kg; range, 50-116 kg) treated by endovascular therapy for MTS from 1998 to 2015. Clinical presentations consisted of acute thrombotic MTS (n = 6) and nonthrombotic MTS (n = 4)...

Abdominal vascular syndromes are rare diseases. Although such syndromes vary widely in terms of symptoms and etiologies, certain imaging findings are characteristic. Depending on their etiology, they can be categorized as congenital-including blue rubber bleb nevus syndrome, Klippel-Trenaunay syndrome, and hereditary hemorrhagic telangiectasia (Rendu-Osler-Weber syndrome)-or compressive-including "nutcracker" syndrome, median arcuate ligament syndrome, Cockett syndrome (also known as May-Thurner syndrome), and superior mesenteric artery syndrome...

AIM: There is firm evidence of a relation between type 2 diabetes (T2DM) and increased risks of cancer at various sites, but it is still unclear how different antihyperglycaemic therapies modify site-specific cancer risks. The aim of this study was to provide a complete characterization of all possible associations between individual T2DM therapies, statin use and site-specific cancers in the Austrian population. METHODS: Medical claims data of 1 847 051 patients with hospital stays during 2006-2007 were used to estimate age- and sex-dependent co-occurrences of site-specific cancer diagnoses and treatment with specific glucose-lowering drugs and statins...

Spontaneous iliac vein rupture resulting in a retroperitoneal hematoma is extremely rare and can present as a life-threatening emergency. There is often a delay in diagnosis with no established treatment recommendations. We report the case of a 39-year-old woman who presented with hypovolemic shock, a large left retroperitoneal hematoma, and left lower extremity phlegmasia in the setting of a previously asymptomatic May-Thurner syndrome. She was successfully treated with a combined open and endovascular approach...

May-Thurner syndrome is the condition of the left common iliac vein being compressed between the right common iliac artery and the associated vertebral body. This condition has been linked to spontaneous episodes of deep vein thrombosis (DVT), especially in women aged 20-50, and it may contribute to the slightly higher tendency to develop left-sided (~56%) versus right-sided DVTs. A 50-year-old morbidly obese (BMI 42.7 kg/m(2)) female presented to the emergency room with acute left leg pain. Past medical history included asthma...

STUDY DESIGN: Cross-sectional study. OBJECTIVE: To explore the underlying anatomy of May-Thurner syndrome (MTS) using computed tomography (CT) and discuss its clinical significance for typing diagnosis. SUMMARY OF BACKGROUND DATA: Because the anatomical position of the corpse cannot fully illustrate the actual clinical situation in vivo, the diversity of MTS has not been fully elucidated yet. METHODS: We retrospectively analyzed the data of 69 patients with MTS...

The purpose of this study was to determine the prevalence of May-Thurner syndrome (MTS) in patients with cryptogenic stroke and to determine the incidence of patent foramen ovale. Magnetic resonance venography of 214 patients with cryptogenic stroke and 50 control patients with abdominopelvic computed tomography scans were evaluated for MTS. Incidence of patent foramen ovale and MTS in the stroke group were significantly greater than the control group (P = 0.0001, P = 0.0023, respectively). In addition, there was significantly greater compression of the left common iliac vein in the stroke group (32%) compared with the control group (13%) (P < 0...
