Klinik und Poliklinik für Orthopädie und Sportorthopädie, Klinikum rechts der Isar, Technische Universität München.

In addition to their outstanding significance in the field of tumor orthopaedics, megaprostheses are becoming increasingly important for revision arthroplasty. Despite their wide application, the reported complication and failure rates remain high. The analysis of failure mechanisms roughly allows a breakdown into mechanical and non-mechanical causes; soft-tissue failure, loosening and periprosthetic infection play outstanding roles. Read More

Ventilator-associated pneumonia remain frequent and serious diseases since they are associated with considerable crude mortality. Pathophysiology is centered on modifications of regional bacterial flora, especially tracheobronchial tree and oropharyngeal sphere. Bacterial migration from an anatomical area to another seems to be the main explanation of these alterations which are called "transcolonization". Read More

Sex-Specific Association between Prenatal Life Stress Exposure and Infant Pro-Inflammatory Cytokine Levels during Acute Respiratory Infection.

Brain Behav Immun 2018 Dec 11. Epub 2018 Dec 11.

Department of Medicine, Division of Allergy, Pulmonary, and Critical Care Medicine, Vanderbilt University Medical Center, Nashville, Tennessee, 37232-2650, USA.

Background: Prenatal life stress exposure is linked to dysregulated immune function and chronic inflammatory disease in offspring, but we know little about its effects on infant immune response during viral infection.

Method: To address this issue, we examined associations between prenatal life stress exposure and infant upper-airway inflammatory markers during acute respiratory infection (ARI) using data from a prospective, population-based birth-cohort study (N=180). Infant inflammation was measured as a continuous latent factor within a structural equation modeling framework using nasal wash concentrations of interleukin-1β, interleukin-6, and tumor necrosis factor-α.

The helix-to-sheet transition of an HIV-1 fusion peptide derivative changes the mechanical properties of lipid bilayer membranes.

Biochim Biophys Acta Biomembr 2018 Dec 11. Epub 2018 Dec 11.

Forschungszentrum Jülich GmbH, Jülich Centre for Neutron Science at SNS, Oak Ridge National Laboratory, Oak Ridge, TN 37831, United States of America.

A short sequence on the gp41 envelope protein of HIV-1 is integral to infection by the virus. Without this sequence, termed the fusion peptide (FP), the virus is far less effective at fusing with the cellular membrane. One of the interesting features of the isolated FP is that it transitions between an α-helical conformation and a β-sheet conformation in lipid bilayer membranes as a function of lipid composition and concentration, and the transition correlates with fusion.

Department of Microbiology, Faculty of Advanced Sciences, Medical Sciences University Islamic Azad, Tehran, Iran.

Legionella pneumophila causes a severe form of pneumonia known as Legionnaires' disease especially in patients with impaired cellular immune response. In order to prevent the disease, immunogenicity and the level of the induction of protective immunity from the recombinant peptidoglycan-associated lipoprotein (rPAL) against Legionella pneumophila in BALB/c mice was examined. Mice immunized with (rPAL) rapidly increased an antibody response in serum and also displayed a strong activation of both innate and adaptive cell-mediated immunity as determined by antigen-specific splenocyte proliferation, an early production of pro-inflammatory cytokines in the serum and in the splenocyte cultures.

Department of Medicine, Division of Hematology, Stanford University School of Medicine, Stanford, CA, USA. Electronic address:

In vitro cancer cultures, including three-dimensional organoids, typically contain exclusively neoplastic epithelium but require artificial reconstitution to recapitulate the tumor microenvironment (TME). The co-culture of primary tumor epithelia with endogenous, syngeneic tumor-infiltrating lymphocytes (TILs) as a cohesive unit has been particularly elusive. Here, an air-liquid interface (ALI) method propagated patient-derived organoids (PDOs) from >100 human biopsies or mouse tumors in syngeneic immunocompetent hosts as tumor epithelia with native embedded immune cells (T, B, NK, macrophages).

Safety of endoscopy in cancer patients with thrombocytopenia and neutropenia.

Gastrointest Endosc 2018 Dec 11. Epub 2018 Dec 11.

The University of Texas MD Anderson Cancer Center, Department of Gastroenterology, Hepatology and Nutrition. Electronic address:

Background And Aims: Cancer patients are prone to thrombocytopenia and neutropenia, which increase the risk of bleeding and infection. We assessed the safety of endoscopic procedures in cancer patients with thrombocytopenia and/or neutropenia.

Methods: We studied consecutive cancer patients with thrombocytopenia and/or neutropenia who underwent endoscopic procedures from 2010 through 2015. Read More

A structural and functional perspective on the enzymes of Mycobacterium tuberculosis involved in the L-rhamnose biosynthesis pathway.

Prog Biophys Mol Biol 2018 Dec 11. Epub 2018 Dec 11.

School of Chemistry, University of Hyderabad, Hyderabad, Telangana, 500046, India. Electronic address:

Tuberculosis is one of the leading causes of death from bacterial infections. The multi-drugresistant strain has warranted the development of new drug molecules which can inhibit the growth of Mycobacterium tuberculosis. Most of the known drugs inhibit the enzymes in the cell wall biosynthesis. Read More

Predictor of Slower Gastric Emptying in Gastroesophageal Reflux Disease-Survey of An Asian-Pacific Cohort.

J Gastroenterol Hepatol 2018 Dec 14. Epub 2018 Dec 14.

Department of Medicine, College of Medicine, Kaohsiung Medical University, Kaohsiung, Taiwan.

Background: Asian populations have relatively lower prevalence of gastroesophageal reflux disease and tend to exhibit symptoms of prolonged gastric retention. However, it remains unknown if slower gastric empting influences its features in Asian countries.

Aim: We prospectively assessed the potential implications of slower gastric emptying in an Asian-Pacific cohort of gastroesophageal reflux disease by a hospital-based survey. Read More

Interferon-gamma production in Lyme arthritis synovial tissue promotes differentiation of fibroblast-like synoviocytes into immune effector cells.

Cell Microbiol 2018 Dec 14:e12992. Epub 2018 Dec 14.

Center for Immunology & Inflammatory Diseases, Division of Rheumatology, Allergy, & Immunology, Massachusetts General Hospital and Harvard Medical School, Boston, MA, USA.

Lyme arthritis (LA), a late disease manifestation of Borrelia burgdorferi infection, usually resolves with antibiotic therapy. However, some patients develop proliferative synovitis lasting months to several years after spirochetal killing, called post-infectious LA. In this study, we phenotyped hematopoietic and stromal cell populations in the synovial lesion ex vivo and used these findings to generate an in vitro model of LA using patient-derived fibroblast-like synoviocytes (FLS).

Translating preventive chemotherapy prevalence thresholds for Schistosoma mansoni from the Kato-Katz technique into the point-of-care circulating cathodic antigen diagnostic test.

PLoS Negl Trop Dis 2018 Dec 14;12(12):e0006941. Epub 2018 Dec 14.

Swiss Tropical and Public Health Institute, Basel, Switzerland.

Background: Intervention guidelines against Schistosoma mansoni are based on the Kato-Katz technique. However, Kato-Katz thick smears show low sensitivity, especially for light-intensity infections. The point-of-care circulating cathodic antigen (POC-CCA) is a promising rapid diagnostic test detecting antigen output of living worms in urine and results are reported as trace, 1+, 2+, and 3+.
