Subsurface flow in a southern Illinois fragipan soil

In an eight-year study of precipitation and water-yield relationships on the Lake Glendale Watershed, Boggess et al (1965) suggested that the nature of the underlying fragipan soil had a significant effect on the flow characteristics of the drainage. The outflow hydrographs were characterized by sustained recession legs, indicating a substantial amount of detained or delayed flow. The authors stated, "Water yield was composed of both surface (overland) and subsurface flow. ...subsurface flow was a major contributor to total yield, due both to the presence of the slowly permeable fragipan and the relatively low moisture storage capacities of the soil profiles." Subsurface flow was believed to be largely made up of downslope seepage along the top of the fragipan, since a perched water table formed there during prolonged periods of wet weather. No attempt was made in their study to determine the relative amounts of surface and subsurface f low. Research reported in this paper was directed toward determining the contribution of each of these flow components in the total water yield from the Grantsburg soiIs.U.S. Department of the InteriorU.S. Geological SurveyOpe

Preoperative quality of life and surgical outcomes in gynecologic oncology patients: A new predictor of operative risk?

Quality of life (QoL) for women with gynecologic malignancies is predictive of chemotherapy related toxicity and overall survival but has not been studied in relation to surgical outcomes and hospital readmissions. Our goal was to evaluate the association between baseline, pre-operative QoL measures and 30-day post-operative morbidity and health resource utilization by gynecologic oncology patients

Preoperative quality of life and surgical outcomes in gynecologic oncology patients: A new predictor of operative risk?

OBJECTIVE: Quality of life (QoL) for women with gynecologic malignancies is predictive of chemotherapy related toxicity and overall survival but has not been studied in relation to surgical outcomes and hospital readmissions. Our goal was to evaluate the association between baseline, pre-operative QoL measures and 30-day post-operative morbidity and health resource utilization by gynecologic oncology patients. METHODS: We analyzed prospectively collected survey data from an institution-wide cohort study. Patients were enrolled from 8/2012 – 6/2013 and medical records data was abstracted (demographics, comorbid conditions, and operative outcomes). Responses from several validated health-related QoL instruments were collected. Bivariate tests and multivariable linear and logistic regression models were used to evaluate factors associated with QoL scores. RESULTS: Of 182 women with suspected gynecologic malignancies, 152 (84%) were surveyed pre-operatively and 148 (81%) underwent surgery. Uterine (94; 63.5%), ovarian (26; 17.5%), cervical (15; 10%), vulvar/vaginal (8; 5.4%), and other (5; 3.4%) cancers were represented. There were 37 (25%) cases of postoperative morbidity (PM), 18 (12%) unplanned ER visits, 9(6%) unplanned clinic visits, and 17 (11.5%) hospital readmissions(HR) within 30 days of surgery. On adjusted analysis, lower functional well-being scores resulted in increased odds of PM (OR 1.07, 95%CI 1.01-.1.21) and HR (OR 1.11, 95%CI 1.03-1.19). A subjective global assessment score was also strongly associated with HR (OR 1.89, 95%CI 1.14, 3.16). CONCLUSION: Lower pre-operative QoL scores are significantly associated with post-operative morbidity and hospital readmission in gynecologic cancer patients. This relationship may be a novel indicator of operative risk
