Abstract

Background: Migraine is a recurrent disease which its definitive mechanism is still unknown. Thus mitochondrial dysfunction and neurovascular damage are two hypothetical underlying mechanisms for migraine headaches. The effectiveness of some possibly effective compounds such a CoQ10 has been studied. In this study, we evaluated the efficacy of coenzyme Q10 in migraine headache prophylaxis.
Methods: This study was performed as a double-blinded randomized clinical trial on 112 patients with a diagnosis of migraine who were referred to the Neurology Clinic of Imam Reza Hospital in Kermanshah from March to September 2018. Then the patients were randomly divided into two equal groups (control and intervention). Both groups received propranolol 20 mg twice daily (totally 40 mg/d). The intervention group was treated by CoQ10 60 mg once daily, additionally. Finally, the quantitative and qualitative characteristics of migraine headaches such as nausea and vomiting, photophobia, phonophobia, severity, frequency and duration of attacks were evaluated by Student's t-test, Mann-Whitney U test and Wilcoxon tests.
Results: At the end, it was concluded that CoQ10 supplement of 60 mg daily with propranolol 40 mg daily in patients with migraine headaches improves symptoms more than receiving propranolol 40 mg alone. The results also showed that in the intervention group, nausea and vomiting, photophobia and the severity of headache in patients significantly improved compared to the control group (P values of 0.001, 0.114 and 0.001, respectively). However, the symptoms of phonophobia, frequency and duration of headache attack in the intervention group were not significantly different from the control group (P values were 0.062, 0.853 and 0.106, respectively).
Conclusion: In conclusion considering the main goal of this study, consumption of CoQ10 60 mg daily with propranolol 40 mg daily significantly improves symptoms such as nausea and vomiting, photophobia and severe headache compared to propranolol 40 mg daily. In conclusion, CoQ10 is a suitable choice in patients who do not respond adequately to the standard drug regimen.

Abstract
Background: Although cervical cancer in adult women with early diagnostic tests has better treatment ability and disease management, precise and fast diagnosis of any signs of cervical intraepithelial neoplasia (CIN) I-III and high-risk dysplasia is vital. If any precancerous/abnormal suspicious cells are not detected in the routine diagnostic process (pathology), they cannot be treated before the lesion turns into cervical cancer, consequently help increasing the patient’s survival rate.
Methods: In this clinical study, the efficiency and diagnostic accuracy of the electrochemical measuring device of glycolysis metabolism in cancer cells (HEA: Hypoxia electrochemical assay) on in-vitro human fresh cervical samples were studied. The samples were prepared from 40 candidates of conization through a history of abnormal cell presentation in their pap smear results. The study was conducted at the Gynecology Department, Yas Hospital, Tehran University of Medical Sciences, and assistant hospitals from August 2018 to June 2021. Patients provided consent according to an ethically approved protocol. A CIN-based scoring of HEA responses was proposed by considering the pathology reports of HEA-tested regions.
Results: The diagnostic calibration of the sensor was achieved by comparing the ROS/H2O2 electrochemical current related to cell glycolysis with the presence of cancer cells in the samples' histology. The current diagnostic threshold obtained by the sensor to differentiate cancerous areas from others showed an accuracy of 95% (P<0.0001). The accuracy and sensitivity of the sensor were 95% and 100%, respectively. Therefore, a matched clinical diagnostic classification between the pathological results of tested tissues and the sensor's electrochemical ROS/H2O2 response was proposed based on CIN categorization.
Conclusion: Further pathological evaluation of the tested samples showed that electrochemical detection of glycolysis metabolism in cervical conization specimens could detect 10% of CIN lesions missed by conventional pathology of assayed patients, which was confirmed in the pathology re-examination. Therefore, as a complementary method, it can help better diagnose CIN lesions in the conization.
