A highly efficient and environmentally benign procedure for the synthesis of quinazoline derivatives via the condensation of carbonyl compounds with 2-aminobenzamide using zirconium tetrakis(dodecyl-sulfate) [Zr(DS)4] as a highly efficient, reusable Lewis acid-surfactant-combined catalyst is described. A broad range of substrates including aldehydes and ketones are successfully condensed with 2-aminobenzamide and all reactions are completed in short times and the products are obtained in good to excellent yields. The catalyst could be recycled and reused several times without any loss of efficiency. Moreover, presented procedure has been applied successfully for the synthesis of spiro-quinazolinones and fused ring-quinazolinone derivatives.

OBJECTIVES: The survival rate of thalassemia patients has not been conclusively established, and the factors associated with survival remain unclear. This study aimed to determine the survival rate of thalassemia among patients in southern Iran and to identify the factors associated with mortality from thalassemia. METHODS: This retrospective cohort study was conducted based on a retrospective review of the medical records of 911 beta-thalassemia patients in 2014. Data analysis was conducted using the Kaplan-Meier method and Cox regression analysis. RESULTS: Overall, 212 patients (23.3%) died, and 26.8% had thalassemia intermedia. The 20-year, 40-year, and 60-year survival rates were 85%, 63%, and 54%, respectively. Both crude and adjusted analyses found that education, marital status, ferritin levels, and comorbidities were related to mortality. CONCLUSIONS: Sociodemographic and hematological factors were found to be significantly associated with the survival rate of thalassemia. Addressing these factors may help healthcare providers and physicians to provide the best possible care and to improve the survival rate.
