Predictors of stent thrombosis and their implications for clinical practice.

Nat Rev Cardiol 2018 Dec 5. Epub 2018 Dec 5.

Kardiologie I, Zentrum für Kardiologie, University Medical Center Mainz and DZHK Standort Rhein-Main, Mainz, Germany.

Stent thrombosis (ST) is a rare but severe complication of coronary procedures with high mortality, high relapse rate and a very complex pathophysiology. An individual's susceptibility to ST is multifactorial and results from interactions between clinical factors, endothelial biology, hypersensitivity and/or inflammatory reactions, blood rheology, platelet reactivity, clotting factors, physical and mechanical properties of the stent and from the effects of these different factors on the fluid dynamics of blood flow. Since the introduction of stents 32 years ago, continuous improvements in our understanding of the pathophysiology of ST have triggered important advances, including new therapies, new technologies and an increased awareness of the implications of implantation techniques.

Leucine-rich repeat extensin proteins regulate plant salt tolerance in .

Proc Natl Acad Sci U S A 2018 Dec 4. Epub 2018 Dec 4.

Shanghai Center for Plant Stress Biology and Center of Excellence in Molecular Plant Sciences, Chinese Academy of Sciences, 200032 Shanghai, China;

The perception and relay of cell-wall signals are critical for plants to regulate growth and stress responses, but the underlying mechanisms are poorly understood. We found that the cell-wall leucine-rich repeat extensins (LRX) 3/4/5 are critical for plant salt tolerance in The LRXs physically associate with the RAPID ALKALINIZATION FACTOR (RALF) peptides RALF22/23, which in turn interact with the plasma membrane-localized receptor-like protein kinase FERONIA (FER). The triple mutant as well as mutant plants display retarded growth and salt hypersensitivity, which are mimicked by overexpression of / Salt stress promotes S1P protease-dependent release of mature RALF22 peptides.

Spontaneous and stimulus-evoked respiratory rate elevation corresponds to development of allodynia in spinal cord injured rats.

J Neurotrauma 2018 Nov 29. Epub 2018 Nov 29.

Respiratory complications frequently accompany spinal cord injury (SCI), and slowed breathing has been shown to mitigate pain sensitivity. It is possible that elevated respiratory rates (RRs) signal the emergence of chronic pain after SCI. We previously validated the use of remote electric field sensors to non-invasively track breathing in freely behaving rodents. Read More

Experience with generic pegylated L-asparaginase in children with acute lymphoblastic leukemia and monitoring of serum asparaginase activity.

Pediatr Hematol Oncol 2018 Nov 29:1-10. Epub 2018 Nov 29.

b Department of Research , Sir Ganga Ram Hospital , New Delhi , India.

Background: Pegylated asparaginase (P-Asp) though integral to acute lymphoblastic leukemia (ALL) therapy is often not accessible to patients in developing countries. We share our clinical experience with generic P-Asp along with monitoring of asparaginase activity.

Methods: In this prospective observational study, patients ≤18 years of age with ALL were assigned to receive either generic P-Asp or native asparaginase (N-Asp) in a non-randomized manner. Read More

Anaphylactic shock with methylprednisolone, Kounis syndrome and hypersensitivity to corticosteroids: a clinical paradox.

Ital J Pediatr 2018 Nov 28;44(1):143. Epub 2018 Nov 28.

Krankenhaus der Barmherzigen Brüder, Trier, Germany.

Corticosteroids are widely used for the treatment of allergic reactions but paradoxically themselves may induce acute, delayed, local or systemic allergic reactions and even anaphylaxis with Kounis syndrome. They can suppress the release of arachidonic acid from mast cell membranes, via phospholipase A2 and eicosanoid biosynthesis inhibition. Corticosteroids can promote cell apoptosis and mediate in annexin or lipocortin synthesis, substances that modulate inflammatory cell activation, adhesion molecule expression, transmigratory and phagocytic functions.

Pterostilbene Attenuates Hexavalent Chromium-Induced Allergic Contact Dermatitis by Preventing Cell Apoptosis and Inhibiting IL-1β-Related NLRP3 Inflammasome Activation.

J Clin Med 2018 Nov 27;7(12). Epub 2018 Nov 27.

Department of Food Safety/Hygiene and Risk Management, College of Medicine, National Cheng Kung University, Tainan 70101, Taiwan.

Hexavalent chromium (Cr(VI)) is widely used in many industries but can induce contact dermatitis especially in cement industries. Many cement workers suffer from Cr(VI)-induced allergic contact dermatitis (ACD), and prevention and therapeutic strategies are still lacking. Pterostilbene (PT) is a natural compound predominantly found in blueberries. Read More

Immediate-Type Hypersensitivity Cross-Reactions to Proton Pump Inhibitors: A Descriptive Study of Data from the French National Pharmacovigilance Database.

Int Arch Allergy Immunol 2018 Nov 28:1-8. Epub 2018 Nov 28.

Clinical Pharmacology Department, Institute of Biology, CHU Nantes, Nantes, France.

Background: Proton pump inhibitors (PPIs) can trigger immediate-type hypersensitivity reactions (HSRs). Three main patterns of cross-reactivity have been identified: reactions to a single PPI, selective cross-reactions, and cross-reactions with all PPIs. Several hypotheses have been advanced, but no consensus has been reached. Read More

Transcription factor MafB contributes to the activation of spinal microglia underlying neuropathic pain development.

Glia 2018 Nov 28. Epub 2018 Nov 28.

Department of Life Innovation, Graduate School of Pharmaceutical Sciences, Kyushu University, Fukuoka, Fukuoka, Japan.

Microglia, which are pathological effectors and amplifiers in the central nervous system, undergo various forms of activation. A well-studied microglial-induced pathological paradigm, spinal microglial activation following peripheral nerve injury (PNI), is a key event for the development of neuropathic pain but the transcription factors contributing to microglial activation are less understood. Herein, we demonstrate that MafB, a dominant transcriptional regulator of mature microglia, is involved in the pathology of a mouse model of neuropathic pain. Read More

DRESS/DIHS caused by levofloxacin in a patient with systemic scleroderma, rheumatoid arthritis, and Sjogren syndrome.

Contact Dermatitis 2018 Nov 28. Epub 2018 Nov 28.

Department of Endocrinology, Metabolism and Nephrology, Kochi Medical School, Nankoku, Kochi, Japan.

Drug-induced hypersensitivity syndrome (DIHS) or drug reaction with eosinophilia and systemic symptoms (DRESS) is a rare, severe skin disease with manifestations such as fever, eosinophilia, lymphadenopathy and internal organ damage that typically develops 2 to 6 weeks after drug intake. DRESS/DIHS follows a prolonged course involving frequent flare-ups and relapses over weeks or months after treatment discontinuation. Read More
