Long-Term Results of Femorodistal Sequential Composite-Bypass Combining Heparin-Bonded PTFE-Prosthesis and Autologous Vein Using the Deutsch Bridge Technique in Critical Limb-Threatening Ischemia.

Background: Autologous vein bypass provides excellent long-term results in critical limb-threatening ischemia (CLTI), but a substantial portion of patients have insufficient vein length. In limbs with two distal outflow vessels and limited vein length, a vascular prosthesis may be combined with autologous vein for a sequential composite bridge bypass (SCBB). Results regarding graft function, limb salvage and reinterventions are presented.

Prevalence of Mental Disorders and Impact on Quality of Life in Patients With Pulmonary Arterial Hypertension.

Mental health may affect the quality of life (QoL) in patients with pulmonary arterial hypertension (PAH). However, mental disorders have not been systematically assessed in these patients. We examined the prevalence of mental disorders using structured interviews and determined their impact on QoL in patients with PAH.

Exploring the sequence variability of polymerization-involved residues in the production of levan- and inulin-type fructooligosaccharides with a levansucrase.

The connection between the gut microbiome composition and human health has long been recognized, such that the host-microbiome interplay is at present the subject of the so-called "precision medicine". Non-digestible fructooligosaccharides (FOS) can modulate the microbial composition and therefore their consumption occupies a central place in a strategy seeking to reverse microbiome-linked diseases. We created a small library of Bacillus megaterium levansucrase variants with focus on the synthesis of levan- and inulin-type FOS.

Balloon-Expandable Vascular Covered Stent in the Treatment of Iliac Artery Occlusive Disease: 9-Month Results from the BOLSTER Multicenter Study.

Purpose: This study sought to assess the performance of the LIFESTREAM balloon-expandable covered stent for the treatment of iliac artery atherosclerotic lesions.

Methods: A total of 155 patients were treated in a prospective, single-arm study at 17 centers in the United States, Europe, and New Zealand. The primary endpoint was a composite of device- or procedure-related death or myocardial infarction (MI) over the course of 30 days, or target lesion revascularization (TLR), major amputation of the target limb, or re-stenosis through 9-months.

Treatment with low-dose tacrolimus inhibits bleeding complications in a patient with hereditary hemorrhagic telangiectasia and pulmonary arterial hypertension.

Pulmonary arterial hypertension (PAH) can be found in patients suffering from a loss-of-function mutation of the gene encoding for the activin receptor-like kinase 1 (ALK-1), a bone morphogenetic protein (BMP) type 1 receptor. Interestingly, ALK-1 mutations also lead to hereditary hemorrhagic telangiectasia (HHT), an autosomal dominant disease characterized by arteriovenous malformations (AVMs) leading to potentially life-threatening bleeding complications such as epistaxis. Current therapeutic options for both diseases are limited and often only temporary or accompanied by severe side effects.
