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.

Abstract
Background: Nowadays, understanding healthy treatment strategies is crucial in the post-COVID era where immunocompromised patients are more likely to get exposure to fungal infections. The aim of the research was to investigate studies of fungal infections after COVID-19.
Methods: The systematic review study was conducted from 11 July 2023 to 04 February 2024 in Zahedan, Iran. To extract articles on fungal infections, the vocabulary of selected Medical Subjects Headings (Mesh), other specialized literature was determined and a search strategy was formulated in three databases, Web Science, Scopus, and PubMed, without any time limitation. In addition, the articles were analyzed according to the research objectives, types of fungal infections encountered in immunocompromised patients, their incidence in different immunocompromised patient groups, diagnostic and detection strategies, treatment methods and other background information.
Results: A 15 number of related articles were included. The most common type of study was case report. From the lens of Aspergillus and mucormycosis fungal infections, they were given more attention, and in terms of the type of immunodeficiency, patients with a history of diabetes, including groups of diabetic patients, cancer groups, AIDS patients, and some groups with genetic disorders, were investigated in the studies. Appropriate treatment methods; particularly the use of corticosteroid drugs such as methylprednisolone as intravenous injection, systemic antifungal drugs such as liposomal amphotericin B, Antifungal treatment using high-dose amphotericin B, the use of prophylactic drugs, and isolation of the damaged tissue are recommended as the best treatment strategies. In order to prevent fungal infections in groups of Immunocompromised Patients, it is recommended to use simple hygiene Recommendations.
Conclusion: Analyzing the conditions of cocvid-19 patients and recognizing effective treatment strategies is inevitable, especially in the post- COVID era. A review of the literature showed that prevention and control of fungal infections after covid-19 was critical among immunodeficiency patients and the use of the recommended treatment method for their lifecycle continuity should be more considered by health care providers, health system managers and health policy makers.
