EVALUATING THE INFLUENCE OF FRAILTY IN SURVIVAL ANALYSIS OF CANCER PATIENTS IN NORTH-WESTERN NIGERIA

Not much is known about the influence of frailty along side otherexplanatory variables on cancer patients’ survival in the north-western Nigeria. In this work, the impact of variables; age sex cancer type, and frailty on patient survival has been estimated using Cox proportional hazards model. Fitting the model to the cancer data obtained from Ahmadu Bello University Teaching Hospital (ABUTH) Zaria, Cancer Registry Center, the results indicate that the covariates studied are relevant prognostic factors to patients’ survival. Also, presence of frailty has impact on the estimates. Female patients were found to be slightly more prone to failure than the male patients. Key words:Cancer Survival, Covariates, Frailty, Cox Proportional Hazards

DELINEATION OF FLOOD PLAIN EXTENSION

Floodplain delineation is an effective approach in either avoiding of water crisis or making pragmatic decisions in terms of water management strategies. In this study a flood plain extension has been developed in ArcGIS and HE-CRAS models and a comparison has been made within three different scenarios of discharge. The results showed in low and medium discharge scenarios the buffer zone acts as a safety factor zone to adjacent infrastructure either agricultural or residential, but in high discharge condition buffer zone is entirely filled with stream water hence yet more safety regulation should be considered in order to avoid human and resource loss or damage within adjacent areas.
