Objective The sudden outbreak of COVID-19 has caused major health problems, including anxiety in cancer patients worldwide. Spiritual health and mindfulness are considered as factors affecting anxiety. This study addressed the relationship between COVID-19 anxiety, spiritual health and mindfulness in patients with cancer.Methods One hundred and eighty-four cancer patients participated in this cross-sectional study. The data were collected with convenience sampling method from two oncology centers from 15 June to 15 July 2020 in the southeast Iran. Patients completed the Demographic and Clinical Characteristics Form, Corona Disease Anxiety Scale (CDAS), The Freiburg Mindfulness inventory-Short Form (FMI-SF) and Spiritual Health Scale.Results According to the psychological symptom subscale (CDAS), 61.4% of the participants had moderate to severe anxiety. According to the physical symptom subscale, 38% of the participants had moderate to severe anxiety. No significant association was found between corona disease anxiety and mindfulness/spiritual health (p>0.05).Conclusion The results of this study showed high levels of mental and physical anxiety and worries about COVID-19 disease in cancer patients, which led to challenges in their lives. It is necessary to review and implement effective interventions in future studies to prevent anxiety and its consequences in cancer patients.
A convenient and rapid one-pot method for the synthesis of iodoarenes is developed which involves the sequential diazotization-iodination of aromatic amines with sodium nitrite, silica sulfuric acid and potassium iodide under solvent-free conditions at room temperature. Various aromatic amines possessing electron-withdrawing groups or electron-donating groups are converted into the corresponding aryl iodides in good yields.
In this study, the possibility of 5-substituted 1-H-tetrazoles synthesis using clays as catalyst was investigated. The reaction of a series of aromatic nitriles with sodium azide was catalyzed by montmorillonite K-10 or kaolin clays in water or DMF as solvent. Conventional heating or ultrasonic irradiation was used to promote reaction. The amount of nitrile to sodium azide mole ratio, amount of catalyst, reaction time, and solvent type were optimized. The versatility of this method was checked by using various nitriles, which showed reasonable yields of tetrazole formation. It was found that using nitriles with electron-withdrawing groups result in both higher yields and lower reaction times. The catalysts could be reused several times without significant loss of their catalytic activity. Compared to conventional heating, ultrasonic irradiation reduced reaction times and increased catalyst activity. The present procedure is green and offers advantages, such as shorter reaction time, simple workup, and recovery and reusability of catalyst.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
