Despite SGD's socioecological salience, few peer-reviewed, empirical studies document the distribution of positive and negative effects. The City of Denton, Texas has ~280 active gas wells and over a decade of SGD. Here we use an environmental justice framework to analyze the distribution of SGD's costs and benefits within Denton. Using data on mineral property values from 2002 to 2013 and gas well locations, we ask: who owns Denton's mineral rights (i.e. the greatest financial beneficiaries) and how does this ownership pattern relate to who lives near gas wells (i.e. those who shoulder the nuisances and health impacts)? Our results showthat Denton's mineral wealth is widely distributed around the U.S., residents own 1% of the total value extracted, and the city government is a large financial beneficiary. In addition to distributional inequities, our analysis demonstrates that split estate doctrine, legal deference to mineral owners, and SGD's uniqueness in urban centers create disparities in municipal SGD decision-making processes. The environmental justice issues associated with fracking in Denton also provide one possible explanation for residents' November 2014 vote to ban hydraulic fracturing.

D. Anderson Cancer Center between 1979 and 2007. We identified 45 patients with penile cancer and nodal metastasis who underwent lymphadenectomy with curative intent. Lymph node density was analyzed as a categorical variable by grouping patients into 2 or 3 categories based on equal percents. We explored the prognostic value of lymph node density for predicting disease specific survival in this cohort.Median followup was 23.7 months in all patients. By the time of analysis 22 patients had died, including 18 (82%) of penile cancer and 4 (18%) of other causes. Median lymph node density in patients alive or dead of other causes was 3.4% (IQR 2.9–5.9) compared to 43.3% (IQR 15.6–80) in those dead of disease (p <0.001). Median lymph node density in all patients was 6.7%. Estimated 5-year disease specific survival in patients with lymph node density 6.7% or less was significantly better than that in patients with lymph node density greater than 6.7% (91.2%, 95% CI 53.9–98.8 vs 23.3%, 95% CI 7.0–45.1, p <0.001). In models comparing lymph node density to known prognostic features lymph node density remained statistically significant, while the other factors were no longer statistically associated with disease specific survival.Lymph node density proved to be a significantly better prognosticator of disease specific survival than the current TNM nodal staging system in patients with penile cancer and nodal involvement. Further independent validation is required to determine the clinical usefulness of lymph node density in this patient population.
