Survival Analysis of Factor Affects Survival Time of Hypertension Patients
TL;DR: The results indicate that the baseline age of the patient, place of residence, family history of hypertension, khat intake, blood cholesterol level of the patients, hypertension disease stage, adherence to the treatment and related disease were significantly associated with survival time of hypertension patients.

Improved Integrated Risk Assessment of Geogenic Arsenic: Exposure and Attributable Health Risks
TL;DR: Evidence is provided that species based risk assessment requires a greater understanding of exposure matrix, toxicological thresholds and metabolic reactions from ingestion to potential endpoints, and is suitable to support future regulatory processes for species based arsenic limits in water together with staple foods.
