Investigation of the international comparability of population-based routine hospital data set derived comorbidity scores for patients with lung cancer.
Thorax
April 2018
National Cancer Registration and Analysis Service, Skipton House, Public Health England, London, UK.
Article Synopsis
- - The study examines variations in lung cancer survival across countries involved in the International Cancer Benchmarking Partnership (ICBP) and explores how comorbid diseases might affect these differences but highlights a lack of quantifiable data on this impact.
- - Researchers analyzed lung cancer registry and hospital data from nine jurisdictions, using three different comorbidity scores (Charlson, Elixhauser, and inpatient bed day) related to patients' health prior to their diagnosis, involving over 233,000 individuals.
- - Findings suggest that while it was possible to create valid comorbidity scores for each jurisdiction, the differences in coding and admission practices limit the comparability of this data internationally, indicating a need for a standardized comorbidity index before assessing its
The formation of Charon's red poles from seasonally cold-trapped volatiles.
Nature
November 2016
Lunar and Planetary Institute, Houston, Texas, USA.
A unique feature of Pluto's large satellite Charon is its dark red northern polar cap. Similar colours on Pluto's surface have been attributed to tholin-like organic macromolecules produced by energetic radiation processing of hydrocarbons. The polar location on Charon implicates the temperature extremes that result from Charon's high obliquity and long seasons in the production of this material.

Addict Behav

Department of Psychology, Loyola Marymount University, Los Angeles, CA 90045, United States.
Studies examining representations of college drinking on social media have almost exclusively focused on Facebook. However, recent research suggests college students may be more influenced by peers' alcohol-related posts on Instagram and Snapchat, two image-based platforms popular among this demographic. One potential explanation for this differential influence is that qualitative distinctions in the types of alcohol-related content posted by students on these three platforms may exist.

PLoS One
January 2013
Dalla Lana School of Public Health, University of Toronto, Toronto, Ontario, Canada.
Background: Research has shown that people from higher socioeconomic status (SES) have better hepatocellular carcinoma (HCC) survival outcomes, although no such research has been carried out in Canada. We aimed to assess if an association between SES and HCC survival existed in the Canadian context.
Methodology/principal Findings: We conducted a population-based cohort study linking HCC cases identified in the Ontario Cancer Registry between 1990 and 2009 to administrative and hospital data.
Shortfalls in imputing sarcoidosis to occupational exposures.
Am J Ind Med
April 2013
Thoracic Oncology Program, Earle A Chiles Research Institute, Portland, OR, USA.
The cause of sarcoidosis remains elusive. Reports of elevated sarcoidosis incidence in New York City firefighters and World Trade Center disaster responders have been advanced to support a causal relationship. This inference is open to question due to methodological differences in assessing and computing sarcoidosis incidence in populations versus putative occupational exposures.
