As such, patients that live at a considerable distance of those specialized centers often require rapid interhospital emergent evacuation with Helicopter Emergency Medical Services (HEMS) to be considered for MT. It is not known whether the use of HEMS is equitable across different groups of patients. Read More

Simultaneous Loss of Both Atypical Protein Kinase C Genes in the Intestinal Epithelium Drives Serrated Intestinal Cancer by Impairing Immunosurveillance.

Immunity 2018 Dec 1. Epub 2018 Dec 1.

Cancer Metabolism and Signaling Networks Program, Sanford Burnham Prebys Medical Discovery Institute, La Jolla, CA 92037, USA. Electronic address:

Serrated adenocarcinoma, an alternative pathway for colorectal cancer (CRC) development, accounts for 15%-30% of all CRCs and is aggressive and treatment resistant. We show that the expression of atypical protein kinase C ζ (PKCζ) and PKCλ/ι was reduced in human serrated tumors. Simultaneous inactivation of the encoding genes in the mouse intestinal epithelium resulted in spontaneous serrated tumorigenesis that progressed to advanced cancer with a strongly reactive and immunosuppressive stroma.

Electron injection from mitochondrial transcription factor A to DNA associated with thymine dimer photo repair.

Bioorg Med Chem 2018 Nov 29. Epub 2018 Nov 29.

Department of Chemistry, Graduate School of Science, Kyoto University, Kitashirakawa-Oiwakecho, Sakyo, Kyoto 606-8502, Japan; Institute for Integrated Cell-Material Sciences, Institute for Advanced Study, Kyoto University, Sakyo-ku, Kyoto 606-8501, Japan. Electronic address:

Electron transfer through π-stacked arrays of double-stranded DNA contributes to the redox chemistry of bases, including guanine oxidation and thymine-thymine dimer repair by photolyase. 5-Bromouracil is an attractive photoreactive thymine analogue that can be used to investigate electron transfer in DNA, and is a useful probe for protein-DNA interaction analysis. In the present study using U we found that UV irradiation facilitated electron injection from mitochondrial transcription factor A into DNA. Read More

The Rear Tip Extender for Inflatable Penile Prostheses: Introduction of "Rigidity Factor" and Review of the Literature.

Sex Med Rev 2018 Dec 11. Epub 2018 Dec 11.

Advanced Urological Care, New York, NY, USA.

Introduction: Rear tip extenders (RTEs) are often used in penile prosthesis surgery, and their value and use have varied with the evolution of penile prostheses.

Aim: To review the literature addressing RTEs and to introduce a new term, rigidity factor, which quantifies the ratio of inflatable to non-inflatable component of the cylinders.

Methods: The urologic literature was reviewed for all mention of RTEs. Read More

Survival benefits associated with surgery for advanced non-small cell lung cancer.

J Thorac Cardiovasc Surg 2018 Nov 14. Epub 2018 Nov 14.

UC Davis Comprehensive Cancer Center, UC Davis Health, Sacramento, Calif.

Objective: Overall survival (OS) for advanced stage (IIIA-IV) non-small cell lung cancer (NSCLC) is highly variable, and retrospective data show a survival advantage for patients receiving therapeutic intent pulmonary resection. We hypothesized that this variability in OS can be modeled separately by stage to allow a personalized estimate of OS.

Methods: In a cohort of patients with advanced-stage NSCLC from the National Cancer Database, we assessed the accuracy of Surgical Selection Score (SSS) to predict OS using Cox proportional hazards models and determined by stage the effect of surgery on survival among people with similarly high levels of SSS.

Second-line treatment efficacy and toxicity in older vs. non-older patients with advanced gastric cancer: A multicentre real-world study.

J Geriatr Oncol 2018 Dec 11. Epub 2018 Dec 11.

Department of Oncology, University and General Hospital, Udine, Italy; Department of Oncology, San Bortolo General Hospital, ULSS8 Berica - East District, Vicenza, Italy. Electronic address:

Objectives: Although gastric cancer (GC) incidence rises with age, older patients are poorly represented in clinical trials, whose results are therefore difficult to translate into standard management of older patients. Purpose of this study was to compare clinico-pathological features and survival outcomes between older and non-older patients with advanced GC treated with at least two chemotherapy lines.

Materials And Methods: Clinico-pathological characteristics, basal values, and treatment data of older (≥70 years at second-line start) and non-older patients were compared using chi-square test or 2-tailed Fisher exact test. Read More

Pro Re Nata Drug Use in Nursing Home Residents: A Systematic Review.

J Am Med Dir Assoc 2018 Dec 11. Epub 2018 Dec 11.

Carl von Ossietzky University Oldenburg, Department of Health Services Research, Oldenburg, Germany.

Objectives: In addition to routinely administered long-term medication, complex drug regimens of nursing home residents often include as needed or pro re nata (PRN) medication. However, there has been no systematic evaluation of the frequency and concomitants of PRN medication in nursing homes. The main objective of this systematic review was to provide a current assessment of PRN drug use in nursing homes. Read More

Functional Swallowing Units (FSUs) as organs-at-risk for radiotherapy. PART 2: Advanced delineation guidelines for FSUs.

Radiother Oncol 2018 Dec 11. Epub 2018 Dec 11.

Department of Radiation Oncology, University of Groningen, University Medical Center Groningen, The Netherlands.

Background And Purpose: In a separate article (PART 1), a rationale and explanation of the physiology-and-anatomy-based concept of Functional Swallowing Units (FSUs) was presented. FSUs are swallowing muscles not included in the set of commonly defined swallowing organs at risk (SWOARs). They are involved in three crucial swallowing components: hyolaryngeal elevation (HLE), tongue base retraction (TBR) and tongue motion. Read More

Design and assessment of an active anti-epidermal growth factor receptor (EGFR) single chain variable fragment (ScFv) with improved solubility.

Biochem Biophys Res Commun 2018 Dec 11. Epub 2018 Dec 11.

Department of Biotechnology and Life Science, Tokyo University of Agriculture and Technology, 2-24-16 Nakamachi, Koganei-shi, Tokyo, 184-8588, Japan. Electronic address:

ScFv is emerging as a therapeutic alternative to the full-length monoclonal antibodies due to its small size and low production cost, but its low solubility remains a limiting factor toward wider use. Here, we increased the solubility of an Anti-epidermal growth factor receptor ScFv (Anti-EGFR ScFv) by attaching, a short 12-residue solubility enhancing peptide (SEP) tag at its C terminus. We first estimated the solubility increase by running 500-ns Brownian dynamics (BD) simulations. Read More
