BACKGROUND AND OBJECTIVE: Raynaud's phenomenon (RP) is characterized by transient digital ischemia and is commonly associated with connective tissue disease. Treatment remains unsatisfactory. Here we evaluate the efficacy, safety, and pharmacokinetics of a single dose of the soluble guanylate cyclase stimulator riociguat in RP. METHODS: DIGIT was a double-blind, randomized, placebo-controlled pilot study. Patients with primary or secondary RP were randomized to a single oral dose of riociguat 2 mg or placebo in a cross-over design (7 ± 3 days)...

A 40-year-old gentleman was diagnosed with anti-topoisomerase-I antibody positive diffuse cutaneous systemic sclerosis (SSc). Raynaud's phenomenon, diffuse skin sclerosis and severe interstitial lung disease (ILD) were the onset features causing digital ischemia, disability and dyspnea. He subsequently developed inflammatory polyarthritis (IA) with hands and wrists involvement. His brother had psoriasis. Physical examination showed fingertip pitting scars, subcutaneous calcinosis, skin sclerosis with hyper- and hypopigmentation, flexion and extension contractures and shortened fingers (Figure 1...

INTRODUCTION: Raynaud's phenomenon is the earliest manifestation of systemic sclerosis. Nitroglycerin gel is the only proven topical therapy. METHODS: A 53-year-old woman with systemic sclerosis had topical Rosamarinus officinalis (rosemary) oil, often used in anthroposophic medicine, applied to her hands over 3days and then, separately, olive oil. RESULTS: Thermography images showed significant warming of fingers after rosemary oil, but not after olive oil, coinciding with the patient's subjective experience...

Genomic instability is a major driver of intra-tumor heterogeneity. However, unstable genomes often exhibit different molecular and clinical phenotypes, which are associated with distinct mutational processes. Here, we algorithmically inferred the clonal phylogenies of 6,000 human tumors from 32 tumor types to explore how intra-tumor heterogeneity depends on different implementations of genomic instability. We found that extremely unstable tumors associated with DNA repair deficiencies or high chromosomal instability are not the most intrinsically heterogeneous...

Digital ischemia is associated with atherosclerotic, thromboembolic, or connective tissue diseases. Less often, it can be related to malignancy. Paraneoplastic vascular acrosyndromes (Raynaud's syndrome, acrocianosis, and acronecrosis) are associated with adenocarcinoma and less frequently with hematological malignancies. We report the case of a 45-year-old male, smoker, with a 10-day history of pain, cyanosis, and progressive digital necrosis in both hands. In the previous four months, he noticed painless mass in the right axillary gap, drenching night sweats, and weight loss...

The purpose of this study was to investigate the use of photoacoustic imaging for quantifying fingertip oxygenation as an approach to diagnosing and monitoring Raynaud's phenomenon. After 30 min of acclimation to room temperature, 22 patients (7 patients with secondary Raynaud's associated to Scleroderma and 15 healthy controls) provided informed consent to undergo fingertip Doppler imaging and high-frequency photoacoustic imaging before and 5, 15 and 30 min after cold stimulus (submerged hand in a 15 °C water bath for 1 min)...

Developing a commercial process for the biological production of n-butanol is challenging as it needs to combine high titer, yield, and productivities. Here we engineer Clostridium acetobutylicum to stably and continuously produce n-butanol on a mineral media with glucose as sole carbon source. We further design a continuous process for fermentation of high concentration glucose syrup using in situ extraction of alcohols by distillation under low pressure and high cell density cultures to increase the titer, yield, and productivity of n-butanol production to the level of 550 g/L, 0...

Monopolar spindle 1 (MPS1) occupies a central role in mitosis and is one of the main components of the spindle assembly checkpoint. The MPS1 kinase is an attractive cancer target, and herein, we report the discovery of the clinical candidate BOS172722. The starting point for our work was a series of pyrido[3,4- d]pyrimidine inhibitors that demonstrated excellent potency and kinase selectivity but suffered from rapid turnover in human liver microsomes (HLM). Optimizing HLM stability proved challenging since it was not possible to identify a consistent site of metabolism and lowering lipophilicity proved unsuccessful...

Systemic sclerosis (SSc) is a rare connective tissue disease characterized by autoimmunity, vasculopathy, and progressive fibrosis typically affecting multiple organs including the skin. SSc often is a lethal disorder, because effective disease-modifying treatment still remains unavailable. Vasculopathy with endothelial dysfunction, perivascular infiltration of mononuclear cells, vascular wall remodeling and rarefaction of capillaries is the hallmark of the disease. Most patients present with vasospastic attacks of the digital arteries referred to as 'Raynaud's phenomenon,' which is often an indication of an underlying widespread vasculopathy...

PURPOSE: Primary open angle glaucoma (POAG) patients constitute a heterogeneous group. Identification of phenotypic subtypes among these patients may provide a deeper understanding of the disease and aid associations with genotypes. We describe a phenotype of POAG patients associated with a constellation of systemic disorders; patients with this phenotype appear to be vulnerable to optic nerve damage at low intraocular pressures. MATERIALS AND METHODS: In this retrospective study, we evaluated the medical records of active Jules Stein Eye Institute glaucoma patients from January 1996 to January 2017 and included subjects with POAG, acquired pits of the optic nerve (APON) and at least one of the following: systolic blood pressure persistently ≤100▒mmHg, history of migraine headaches or migraine variant, and Raynaud's syndrome...

Current knowledge on biomarkers of intra-pancreatic fat deposition (IFD) is limited. We aimed to analyse comprehensively body composition and insulin traits as biomarkers of IFD in healthy normoglycaemic individuals as well as individuals with new-onset prediabetes and diabetes after acute pancreatitis (NODAP). A total of 29 healthy and 34 NODAP individuals took part in this cross-sectional study. The studied biomarkers belonged to the following domains: body composition (anthropometry and magnetic resonance imaging (MRI)-derived variables), indices of insulin secretion, indices of insulin sensitivity, incretins and related peptides, as well as pancreatitis-related factors...

Vasospastic disorders in the hand have been treated with surgical sympathectomy and recently with botulinum toxin A (BTX) injections in the palm. The purpose of this study was to evaluate if it is possible to obtain precise administration of BTX around the radial artery using a single ultrasound-guided injection. We present a novel technique using 1 single ultrasound-guided BTX injection around the radial artery to treat vasospastic symptoms. Ten patients were included in a pilot study. All patients were referred by a rheumatologist after been diagnosed with primary or secondary Raynaud...

Raynaud's phenomenon (RP) is a microvascular condition in which reversible ischemic attacks occur in the extremities. Due to the unpredictable nature of these attacks, pharmacologic agents that can be administered on as-needed basis are currently being sought after. Topical nitrates are well suited for as-needed use, and several different formulations have been studied for the treatment of RP, including ointments, gels, patches, and tapes. However, these different dosage forms are not all equal in terms of safety and efficacy, and not every one is commercially available for use in clinical practice...

Myositis-specific (MSAs) or-associated autoantibodies (MAAs) have been linked to particular clinical phenotypes of idiopathic inflammatory myopathies (IIM) and appear to aid diagnosis. The objective of this study was to analyze the prevalence of MSAs and MAAs and their possible clinical associations in Greek IIM patients. This study comprised 95 IIM patients classified based on the 2017 EULAR/ACR classification criteria. All patients had MSAs and MAAs measured in their sera by line immunoblot assay. Dermatomyositis was the most prevalent IIM clinical subtype...
