Decreased numbers of circulating endothelial progenitor cells are associated with hyperglycemia in patients with traumatic brain injury.

Neural Regen Res 2019 Jun;14(6):984-990

Department of Neurosurgery, Tianjin Medical University General Hospital; Tianjin Neurological Institute; Key Laboratory of Post-trauma Neuro-repair and Regeneration in Central Nervous System, Ministry of Education; Tianjin Key Laboratory of Injuries, Variations and Regeneration of Nervous System, Tianjin, China.

Hyperglycemia reduces the number of circulating endothelial progenitor cells, accelerates their senescence and impairs their function. However, the relationship between blood glucose levels and endothelial progenitor cells in peripheral blood of patients with traumatic brain injury is unclear. In this study, 101 traumatic brain injury patients admitted to the Department of Neurosurgery, Tianjin Medical University General Hospital or the Department of Neurosurgery, Tianjin Huanhu Hospital, China, were enrolled from April 2005 to March 2007.

Application of a peripheral vein illumination device to reduce saphenous structure injury caused by screw insertion during arthroscopic ankle arthrodesis.

J Orthop Sci 2019 Jan 7. Epub 2019 Jan 7.

Department of Orthopaedic Surgery, Graduate School of Biomedical & Health Sciences, Hiroshima University, 1-2-3 Kasumi Minamiku, Hiroshima city, 734-8551, Japan.

Background: Arthroscopic ankle arthrodesis (AAA) is minimally invasive surgery, whereby percutaneous screw fixation is used through the medial aspect of the distal tibia to fusion the ankle, but it carries the risk of the saphenous vein and nerve injuries. The near-infrared (NIR) vascular imaging system, the VeinViewer Flex, projects an image of the vein onto the skin, and the visualization of the vein may reduce the vein and nerve injuries. The purpose of this study is to investigate the risk of the saphenous vein injury by the percutaneous screw insertion during AAA, and to evaluate the effectiveness of the NIR vascular imaging system in the reduction of the saphenous vein injury.

Thromboangiitis obliterans episode: autoimmune flare-up or reinfection?

Vasc Health Risk Manag 2018 28;14:247-251. Epub 2018 Sep 28.

Immunology Research Center, Inflammation and Inflammatory Diseases Division, School of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran,

Background: The possible role of infectious pathogens in the development of thromboangiitis obliterans (TAO) was considered soon after the disease was first described. However, it is not yet known whether infectious pathogens induce thrombotic vasculitis or if they cause a type of autoimmune disease. To investigate whether TAO relapses are more likely due to reinfection or autoimmune flare, the serum levels of toll-like receptor (sTLR) 4, sTLR2, C-reactive protein (CRP), and neopterin were evaluated in TAO patients during both the acute and quiescent phases of the disease as well as in a gender-, age-, and smoking habit-matched control group.

Vasodilator function is impaired in burn injury survivors.

Am J Physiol Regul Integr Comp Physiol 2018 Nov 26;315(5):R1054-R1060. Epub 2018 Sep 26.

University of Texas Southwestern Medical Center and Institute for Exercise and Environmental Medicine, Texas Health Presbyterian Hospital , Dallas, Texas.

The effect of severe burn injury on vascular health is unknown. We tested the hypothesis that, compared with nonburn control subjects, vasodilator function would be reduced and that pulse-wave velocity (a measure of arterial stiffness) would be increased in individuals with prior burn injuries, the extent of which would be associated with the magnitude of body surface area having sustained a severe burn. Pulse-wave velocity and macrovascular (flow-mediated dilation) and microvascular (reactive hyperemia) dilator functions were assessed in 14 nonburned control subjects and 32 age-matched subjects with well-healed burn injuries.

Injury-induced perivascular niche supports alternative differentiation of adult rodent CNS progenitor cells.

Elife 2018 09 17;7. Epub 2018 Sep 17.

Laboratory of Molecular Neurobiology, Neurobiology Center, Nencki Institute of Experimental Biology, Polish Academy of Sciences, Warsaw, Poland.

Following CNS demyelination, oligodendrocyte progenitor cells (OPCs) are able to differentiate into either remyelinating oligodendrocytes (OLs) or remyelinating Schwann cells (SCs). However, the signals that determine which type of remyelinating cell is generated and the underlying mechanisms involved have not been identified. Here, we show that distinctive microenvironments created in discrete niches within demyelinated white matter determine fate decisions of adult OPCs. Read More

Infrared Thermographic Analysis of Surface Temperature of the Hands During Exposure to Normobaric Hypoxia.

High Alt Med Biol 2018 Dec 22;19(4):388-393. Epub 2018 Aug 22.

1 Warwick Medical School, University of Warwick , Coventry, United Kingdom .

Frostbite and other cold-related injuries commonly develop during prolonged exposure to the low environmental temperatures of polar and mountainous regions. Hypoxia is a potent sympathetic stimulus that causes vasoconstriction of the peripheral blood vessels, which may further compound the risk of developing a cold-related injury during high-altitude exposure. To investigate this, we utilized portable infrared thermographic technology to quantitatively measure changes in the surface temperature of the hands during exposure to increasing levels of normobaric hypoxia in a temperature-controlled high-altitude simulation.
