Pressure ulcers (PUs) are common debilitating complications of traumatic spinal cord injury (SCI) and tend to occur in soft tissues around bony prominences. There is, however, little known about the impact of SCI on skin wound healing due to the lack of suitable animal models for studies in controlled experimental settings. Herein we describe a reproducible and clinically relevant mouse model of PUs in the context of complete SCI. Adult male mice (BALB/c) were subjected to thoracic (T9-T10) complete SCI. Immediately after, a skin fold on the back of the mice was lifted and sandwiched between two magnetic discs held in place for 12 hours, thus creating an ischemic area that developed into a PU over the following days...

OBJECTIVE: To report 2 cases of superficial siderosis of central nervous system (SS-CNS) and a review of the literature. METHODS: We have analyzed the clinical data and relevant features of two patients with SS-CNS who were presented with ataxia and slurred speech. Both patients undertook blood tests, lumbar puncture, head CT (computer tomography) scans, and brain and spinal cord magnetic resonance (MR) scans. In addition, the first patient also undewent enhanced susceptibility-weighted angiography (ESWAN) and the second patient undertook susceptibility weighted imaging (SWI) scan...

BACKGROUND: Preclinical evidence suggests that general anesthetics can dose dependently induce neurodegeneration in the developing brains of animals which can be reliably determined by measurement of blood S100β, but this correlation remains unclear in humans. We hypothesized that S100β would not be increased in cord arterial blood of fetuses exposed briefly to general anesthetics during a C-section, compared with epidural anesthesia. METHODS: A prospective observational clinical study comparatively measured changes of brain damage biomarker S100β ratio of umbilical artery over vein (changes after fetus circulation) immediately after delivery under C-section with either epidural or general anesthesia...

BACKGROUND/OBJECTIVE: The term macrosomia is used to describe neonates with a birth weight of 4000 g or more. Macrosomia is a potential risk factor for obesity and metabolic syndromes in postnatal and adult life, yet little is known about its associations with metabolic difference in the early-age. We performed metabolic profiling of umbilical cord blood to discover differential metabolites of macrosomia. METHODS: We conducted a case-control study of full-term singletons with normal maternal glucose tolerance [50 cases (macrosomia, birth weight ⩾4000 g); 50 controls (normal weight, birth weight 2500-3999 g)]...

OBJECTIVE: As survival increases at earlier gestational ages, the optimal mode of delivery, especially in cases of breech presentation, is of increasing importance. The objective of this study was to compare outcomes of vaginal delivery (VD) and cesarean section (CS) births for infants in breech presentation at borderline viability. STUDY DESIGN: A retrospective chart review of live breech births between 23 + 0 and 25 + 6 weeks gestation at a tertiary university center from 2003 to 2013 was conducted...

Transfusion-dependent thalassemia (TDT) is an inherited disorder characterized by absent or defective production of α- or β-hemoglobin chains. If untreated, the disease invariably culminates in death in early infancy due to cardiac failure or overwhelming infection. Although there is clear evidence of good health-related quality of life and return to normal life style, the choice to undergo hematopoietic stem cell transplantation (HSCT) remains a challenge because of the potential risk of transplant-related mortality (TRM) in TDT...

Induced pluripotent stem cells (iPSCs) offer the potential to generate tissues with ethnic diversity enabling toxicity testing on selected populations. Recently, it has been reported that endothelial progenitor cells (EPCs) derived from umbilical cord blood (CB) or adult peripheral blood (PB) afford a practical and efficient cellular substrate for iPSC generation. However, differences between EPCs from different blood sources have rarely been studied. In the current study, we derived EPCs from blood mononuclear cells (MNCs) and reprogrammed EPCs into iPSCs...

The nature of traumatic spinal cord injury (SCI) often involves limited recovery and long-term quality of life complications. The initial injury sets off a variety of secondary cascades, which result in an expanded lesion area. Ultimately, the native tissue fails to regenerate. As treatments are developed in the laboratory, the management of this secondary cascade is an important first step in achieving recovery of normal function. Current literature identifies four broad targets for intervention: inflammation, oxidative stress, disruption of the blood-spinal cord barrier, and formation of an inhibitory glial scar...

We previously published results of 70 children who received treosulfan with cyclophosphamide (30) or fludarabine (40) before haematopoietic stem cell transplantation (HSCT) for Primary Immunodeficiency (PID). Toxicity was lower and T cell chimerism better in those receiving fludarabine, but numbers were relatively small and follow-up short. We now report outcome of 160 children who received homogeneous conditioning with treosulfan, fludarabine mostly with alemtuzumab (n=124). Median age at transplant was 1...

BACKGROUND CONTEXT: Aggressive (Enneking Stage 3, S3) vertebral hemangiomas (VHs) are rare, which might require surgery. However, the choice of surgery for S3 VHs remains controversial because of the rarity of these lesions. PURPOSE: We reported our experience of treating S3 VHs, and evaluated the effectiveness and safety of intraoperative vertebroplasty during decompression surgery for S3 VHs. STUDY DESIGN: This is a retrospective study. PATIENT SAMPLE: Thirty-nine patients with a definitive pathological diagnosis of aggressive VHs who underwent primary decompression surgery in our department were included in this study...

Aquaporin-4 (AQP4) is abundantly expressed in the central nervous system and is involved in the water balance in the cellular environment. Previous studies have reported that AQP4 expression is upregulated in rat models of amyotrophic lateral sclerosis (ALS), a fatal disease that affects motor neurons in the brain and spinal cord. In this study, we report that astrocytic AQP4 overexpression is evident during the course of disease in the spinal cord of an ALS mouse model, as well as in tissue from patients with ALS...

A 64-year-old man with acute myeloid leukemia underwent umbilical cord blood transplantation (UCBT). After 11 months of complete remission (CR) following UCBT, the bone marrow showed 7.5% myeloblasts. CR was obtained after a single course of azacitidine monotherapy, but the myeloblasts gradually increased in the blood. We made a diagnosis of acute megakaryoblastic leukemia derived from donor cell with a fluorescence in situ hybridization (FISH) analysis of the sex chromosomes and an immunophenotypic analysis...

Hematopoietic stem cell transplantation has been considered a risk factor for development of platelet transfusion refractoriness. The objective of this study was to assess the platelet transfusion refractoriness rate in patients undergoing allogeneic hematopoietic stem cell transplantation from different sources. We retrospectively reviewed the charts and transfusion records of patients who underwent allogeneic stem cell transplantation at our institution between 2013 and 2015. The evaluation of post-transfusion platelet count was assessed for each transfusion given, from day of progenitor infusion to day 30 after transplantation...

Methylmercury (MeHg) is a neurotoxicant known to affect the developing fetal brain as a sensitive target organ. As most mercury (Hg) in blood is MeHg, total mercury (THg) levels in blood are used to estimate the body burden of MeHg. The nutrients selenium (Se), vitamin E, and docosahexaenoic acid (DHA) are protective against MeHg toxicity. We compared maternal and cord blood concentrations of biochemical substances, THg and Se, vitamin E, DHA, and other elements, fatty acids, and amino acids in 54 Japanese mother-newborn pairs to elucidate the fetal risk of MeHg toxicity...

Preterm birth infants are more susceptible to oxidative stress and aftermaths unwanted outcomes such as DNA damage due to hyperoxic stress. In this study, we compared the DNA strand breaks as one of the results of DNA oxidation in white blood cells, malondialdehyde (oxidative stress marker), catalase and superoxide dismutase activity, and total antioxidant capacity (markers of antioxidant defense) in a cord blood plasma of a group of preterm (n=25) and full term births (n=25). The primary DNA damage and plasma oxidative stress markers were significantly higher in a preterm group (p<0...

BACKGROUND: Mycolactone is a macrolide produced by the skin pathogen Mycobacterium ulcerans, with cytotoxic, analgesic and immunomodulatory properties. The latter were recently shown to result from mycolactone blocking the Sec61-dependent production of pro-inflammatory mediators by immune cells. Here we investigated whether mycolactone similarly affects the inflammatory responses of the nervous cell subsets involved in pain perception, transmission and maintenance. We also investigated the effects of mycolactone on the neuroinflammation that is associated with chronic pain in vivo...

Previous research indicated the association between hepatitis B virus (HBV) infection/vaccination and the onset of demyelinating diseases. However, most of these studies were single case reports, and comprehensive data are still scarce. Here we present a comprehensive analysis of 10 patients with neuromyelitis optica spectrum disorder (NMOSD) combined with chronic hepatitis B (CHB) infection and seropositive for anti-aquaporin-4 antibody (AQP4-Ab). Demographic, clinical, laboratory, neuroimaging, outcome, and follow-up data of the 10 patients were retrospectively analyzed...
