Context And Objective: Being born small or large for gestational age and intrauterine exposure to gestational diabetes (GDM) increase the risk of type 2 diabetes (T2D) in the offspring, however, the potential combined deleterious effects of size at birth and GDM exposure remains unknown. We aimed to examine the independent effect of size at birth as well as the influence of GDM exposure in utero on cardio-metabolic traits, body composition, and puberty status in children.

Design, Participants And Methods: This study is a longitudinal birth cohort study. Read More

Analysis of a lectin microarray identifies altered sialylation of mouse serum glycoproteins induced by whole-body radiation exposure.

J Radiat Res 2018 Dec 6. Epub 2018 Dec 6.

Department of Experimental Oncology, Research Institute for Radiation Biology and Medicine, Hiroshima University, 1-2-3, Kasumi, Minami-ku, Hiroshima, Japan.

Microarrays containing 45 different lectins were analyzed to identify global changes in the glycosylation of serum glycoproteins from mice exposed to whole-body γ-radiation. The results showed that radiation exposure increased and decreased the relative amounts of α-2,3- and α-2,6-sialic acids, respectively. The expression of α-2,3- and α-2,6-sialyltransferase genes in the liver was analyzed to determine whether changes in their expression were responsible for the sialic acid changes. Read More

Short communication: rapid quantitation of flecainide in human plasma for therapeutic drug monitoring using liquid chromatography and time-of-flight mass-spectrometry.

Ther Drug Monit 2018 Dec 4. Epub 2018 Dec 4.

Analytical Services International (ASI), St George's-University of London, Cranmer Terrace, London SW17 0RE, UK.

Background: Measurement of flecainide is useful to optimize dosage and minimize risks of toxicity. Further, there is a need for urgent sample analysis when flecainide is used in transplacental therapy for fetal tachycardia. To this end, we have developed and validated a rapid assay for the measurement of flecainide in human plasma or serum, using a small sample volume (50 µL). Read More

Low serum trough concentrations and high vancomycin MIC in methicillin-sensitive Staphylococcus aureus from hemodialysis patients in Brazil.

Ther Drug Monit 2018 Dec 4. Epub 2018 Dec 4.

Department of Pathology, Health Sciences Center, Federal University of Espírito Santo (UFES), Marechal Campos Ave., 1468, 29040-090 Vitória, Espírito Santo, Brazil.

Background: The empiric antimicrobial therapy for bacteremia of long-term hemodialysis (HD) outpatients is currently based on the combination of vancomycin and gentamicin because of the high frequency of isolated Staphylococcus species. The vancomycin trough level range from 15 to 20 µg/mL is expected for therapeutic success against methicillin-resistant S. aureus with vancomycin MIC ≥ 1. Read More

Diagnosis and Management of Fungal Periprosthetic Joint Infections.

J Am Acad Orthop Surg 2018 Dec 4. Epub 2018 Dec 4.

From the Sinai Hospital of Baltimore, Baltimore, MD (Dr. Nace), the Philadelphia College of Osteopathic Medicine, Philadelphia, PA (Dr. Siddiqi), the New England Baptist Hospital, Boston, MA (Dr. Talmo), and the Brigham and Women's Hospital, Boston, MA (Dr. Chen).

Fungal periprosthetic joint infection (PJI) is a devastating complication because it can be difficult to diagnose, manage, and eradicate. Fungal PJI treatment requires a systematic approach. Increased awareness is essential when patients with painful arthroplasties present with immunosuppression, significant comorbidities, multiple surgeries, and history of drug use. Read More

Thrombospondin-1 and Vitamin D in Children With Sickle Cell Anemia.

J Pediatr Hematol Oncol 2018 Dec 4. Epub 2018 Dec 4.

Department of Pediatrics, Faculty of Medicine, Kuwait University, Kuwait.

Background: Thrombospondin-1 (TSP-1) and 25-hydroxyvitamin D (25-OHD) play significant roles in the pathogenesis of sickle cell anemia (SCA). TSP-1 enhances cellular adhesion/inflammation, hence contributing to vaso-occlusive crisis (VOC); vitamin D, in contrast, retards inflammation and may lower rate of pain episodes. We determined serum levels of TSP-1 and 25-OHD in Nigerian children with SCA and their matched hemoglobin AA controls; and assess the relationship between the 2 biomarkers. Read More

Overexpression of IL-11 promotes premalignant gastric epithelial hyperplasia in isolation from germline gp130-JAK-STAT3 driver mutations.

Am J Physiol Gastrointest Liver Physiol 2018 Dec 6. Epub 2018 Dec 6.

Murdoch Childrens Research Institute, Australia.

Expression of the cytokine IL-11 is elevated in human Helicobacter pylori infection and progressively increases with worsening gastric pathology. Additionally, IL-11 is required for tumour development in STAT3 dependent murine models of gastric cancer (GC) and, when administered acutely, causes resolving atrophic gastritis. However, it is unclear whether locally elevated IL-11 ligand expression can, in isolation from oncogenic gp130-JAK-STAT pathway mutations, initiate GC pathogenesis. Read More
