The Doppler Radar derived rainfall data for over 150 candidate storms during 1997-2015 period, for the County of San Bernardino, California, was assessed. Eleven most significant storms were identified for detailed analysis. for these significant storms, Depth-Area Reduction factors (“DARf”) curves were developed and compared with the published curves developed and adapted by several flood control agencies for this study area. More rainfall data need to be pursued and analyzed before any correlation hypothesis is proposed.

Background: The mortality due to mechanical thrombectomy (MT) in the acute treatment of intracranial arterial occlu- sions can be up to 45%. The SWIfT (Solitaire fR with the Intention for Thrombectomy) and Multi MERCI (mechani- cal embolus removal in cerebral ischemia) trials have evaluated the safety and efficacy of MT. It may be important to determine pre-procedural factors that help predict post-intervention prognosis. We sought to determine if admission medical research council (MRC) motor strength grade along with other factors can be used as predictor of mortality after MT for acute ischemic stroke. Methods: Retrospective analysis of stroke database assessing outcomes in all 62 patients who underwent MT as an intervention for acute ischemic stroke, with or without concurrent intravenous thrombolysis was done. five baseline variables were included in univariate and multivariate analyses to define the in- dependent predictors of mortality during current hospitalization. The medical research council (MRC) motor grade (0 - 5);modified collateral flow (CS) grading (0 - 3);age;acute and chronic co-morbidities were used as the baseline vari- ables. If motor strength grade were different in upper and lower extremities, then the lower grade was used. Age was analyzed independently as well as dichotomized using 80 as cut-off value. Relevant stroke related acute and chronic co-morbidities were given 1 point each and mean calculated. Results: In the univariate analysis, low (0 - 1) motor strength grade (OR, 0.11;95% CI, 0.021 - 0.33;p = 0.001) and age (OR, 1.06;95% CI, 1.02 - 1.12;p = 0.011) was sig- nificantly associated with mortality. The presence of collateral flow, acute and chronic co-morbidities were not signifi- cantly associated with mortality. In the multivariate analysis, motor grade retained its statistical significance for morta- lity (OR, 0.09;95% CI, 0.01 - 0.32;p = 0.003) along with chronic co-morbidity (OR, 1.52;95% CI 1.05 - 2.43;

AIM: To investigate whether regional geography influences ethnic and gender trends for the development of gastric cancer(GC).METHODS: This retrospective analysis of the INVISION patient database at Louisiana State University Health Sciences Center-Shreveport(LSUHSC-S), a southern United States regional hospital, was performed from 2005-2011. Using the international statistical classification of diseases 9(ICD-9), inpatient, day surgery outpatient, and emergency outpatient diagnosis codes entered into medical records were used to identify GC patients. for each study year, the patients were evaluated for age, ethnicity, and gender, and each patient was counted only once throughout the study. Subsequent patient encounters were counted as visits and separated by inpatient and clinic visits. Complex or severe disease may require more frequent and intensive clinical management; therefore, we evaluated annual clinic visits as "surrogate markers" of disease severity. finally, we studied the primary diagnosis for Helicobacter pylori(H. pylori) infection(ICD-9 code 41.86) as an additional factor that might increase the risk of ***: A total of 285 patients were diagnosed with GC at LSUHSC-S between 2005 and 2011. African Americans(181 patients, 89 males and 92 females, 63.5% of total patients) had significantly higher frequencies of GC diagnosis compared with non-Hispanic whites(104 patients, 54 males and 50 females, 36.5% of total patients), at a ratio of 1.74(P = 0.002). Within each ethnic group, men and women were diagnosed at approximately equal annual rates. Our findings differed significantly from United States national trends, which found that African American females and white females had lower risks for GC than their corresponding male counterparts. The United States national trend between 2005 and 2011 showed that African Americans males had a higher incidence of GC, with an annual mean(per 100000) of 16.31 ± 0.76 compared with white males(9 ± 0.1, P < 0.001),
