Cell cycle control by cell-matrix interactions.

Cell adhesion to the extracellular matrix (ECM) is required for normal cell cycle progression and accurate cell division. However, how cell adhesion to the wide range of ECM proteins found in human tissues influences the cell cycle is not fully understood. The composition and physical properties of the ECM can have profound effects on cell proliferation but can also promote cell cycle exit and quiescence.

Threat Appraisal, Recovery Operations, and PTSD Symptoms Among US Air Force Rescue Personnel.

Background: Research among military personnel and veterans indicates that subjective appraisal of warzone stressors explains the relation of combat exposure to posttraumatic stress disorder (PTSD), but not the relation of exposure to injury and death to PTSD. Studies have primarily been limited to conventional forces using aggregate measures of warzone stressor exposure. Threat appraisal may play a different role in the emergence of PTSD among military personnel for whom dangerous deployment experiences are more closely associated with exposure to injury and death, such as US Air Force Pararescuemen and Combat Rescue officers.

Prenatal marijuana exposure and neonatal outcomes: a retrospective cohort study.

Objectives: Previous literature on the effects of marijuana exposure on neonatal outcomes has been limited by the reliance on maternal self-report. The objective of this study was to examine the relationship of prenatal marijuana exposure on neonatal outcomes in infants with marijuana exposure confirmed with meconium drug testing.

Design: Retrospective cohort study.

A Survey of Single-Scene Video Anomaly Detection.

This article summarizes research trends on the topic of anomaly detection in video feeds of a single scene. We discuss the various problem formulations, publicly available datasets and evaluation criteria. We categorize and situate past research into an intuitive taxonomy and provide a comprehensive comparison of the accuracy of many algorithms on standard test sets.

Early warning score independently predicts adverse outcome and mortality in patients with acute pancreatitis.

Purpose: The aim of this study was to compare the prognostic value of established scoring systems with early warning scores in a large cohort of patients with acute pancreatitis.

Methods: In patients presenting with acute pancreatitis, age, sex, American Society of Anaesthesiologists (ASA) grade, Modified Glasgow Score, Ranson criteria, APACHE II scores and early warning score (EWS) were recorded for the first 72 h following admission. These variables were compared between survivors and non-survivors, between patients with mild/moderate and severe pancreatitis (based on the 2012 Atlanta Classification) and between patients with a favourable or adverse outcome.

Clinical risk scores in the current era of neoadjuvant chemotherapy for colorectal liver metastases.

Background: Clinical risk scores (CRS) within the context of neoadjuvant chemotherapy for colorectal liver metastases (CRLM) has not been validated. The predictive value of clinical risk scoring in patients administered neoadjuvant chemotherapy prior to liver surgery for CRLM is evaluated.

Methods: A prospective database over a 15-year period (April 1999 to March 2014) was analysed.

Prognostic performance of inflammation-based prognostic indices in patients with resectable colorectal liver metastases.

A range of prognostic cellular indices of the systemic inflammatory response, namely the neutrophil-lymphocyte ratio (NLR), derived NLR (dNLR), platelet-lymphocyte ratio (PLR), lymphocyte-monocyte ratio (LMR), combination of platelet count and neutrophil-lymphocyte ratio (COP-NLR) and prognostic nutritional index (PNI), have been developed and found to have prognostic utility across varied malignancies. The current study is the first to examine the prognostic value of these six inflammatory scores in patients with resectable colorectal liver metastases (CRLM). Data from 302 consecutive patients undergoing surgery for resectable CRLM were evaluated.
