The effect of counseling based on health promotion awareness on self-care needs and reproductive and sexual health literacy of newly married women: a randomized controlled clinical trial study Fereshteh Kohansal, Roghaiyeh Nourizadeh, Niloufar Sattarzadeh Jahdi, Mahdie Arab Bafrani, Esmat Mehrabi BMC Women S Health, 2024 Background Despite the importance of health literacy and the self-care skills in improving individual and social health and health costs reduction, scientific evidence indicates women’s poor awareness of self-care needs and low health literacy concerning reproductive and sexual health in most societies. The present study was conducted to specify the effect of health awareness promotion on self-care needs and reproductive and sexual health literacy of newly married women. Methods This randomized controlled clinical trial was conducted on 64 newly married women aged 15–45 in Tehran, Iran from August 2021 to the end of December 2021. The participants were randomly assigned into the intervention (n = 32) and control (n = 32) groups. The intervention group received four individual health awareness-promotion education sessions. The reproductive and sexual self-care needs, and sexual health literacy questionnaires, were completed before and 4-week after the intervention through interview. The data were analyzed using SPSS26 software. The independent t-tests and ANCOVA were used to comparison the mean scores and a significance level of P < 0.05 was considered. Results The results of this study indicated that after counseling, the average overall score of perceived reproductive and sexual self-care needs significantly decreased in the intervention group [Mean (standard deviation(SD)): 125.70 (24.70)] compared to the control group [Mean (SD): 87.1 (23.42)][P = 0.001]. Also, the mean score of sexual and reproductive health literacy significantly increased in the intervention group [Mean (SD): 125.50 (14.09)] compared to the control group [Mean (SD): 97.15 (14.90)] after intervention [P = 0.01]. Conclusions The results indicated the positive effect of health promotion awareness educations on reproductive and sexual self-care needs and health literacy among newly married women. Therefore, health promotion interventions should be incorporated in health services provision programs for newly married women in comprehensive health centers to improve the health of women and families.

Nanobiosensors for procalcitonin (PCT) analysis Ahmad Mobed, Mohammad Darvishi, Amir Tahavvori, Iraj Alipourfard, Fereshteh Kohansal, et al. Journal of Clinical Laboratory Analysis, 2024 BackgroundProcalcitonin (PCT) is a critical biomarker that is released in response to bacterial infections and can be used to differentiate the pathogenesis of the infectious process.ObjectiveIn this article, we provide an overview of recent advances in PCT biosensors, highlighting different approaches for biosensor construction, different immobilization methods, advantages and roles of different matrices used, analytical performance, and PCT biosensor construction. Also, we will explain PCT biosensors sensible limits of detection (LOD), linearity, and other analytical characteristics. Future prospects for the development of better PCT biosensor systems are also discussed.MethodsTraditional methods such as capillary electrophoresis, high‐performance liquid chromatography, and mass spectrometry are effective in analyzing PCT in the medical field, but they are complicated, time‐consuming sample preparation, and require expensive equipment and skilled personnel.ResultsIn the past decades, PCT biosensors have emerged as simple, fast, and sensitive tools for PCT analysis in various fields, especially medical fields.ConclusionThese biosensors have the potential to accompany or replace traditional analytical methods by simplifying or reducing sample preparation and making field testing easier and faster, while significantly reducing the cost per analysis.
An Innovative Electrochemical Immuno-Platform for Monitoring Chronic Conditions Using the Biosensing of Hyaluronic Acid in Human Plasma Samples Ahmad Mobed, Fereshteh Kohansal, Sanam Dolati, Mohammad Hasanzadeh, Seyed Kazem Shakouri Chemosensors, 2023 Hyaluronic acid (HA) is the main non-sulfated glycosaminoglycan of the extracellular matrix that is synthesized by fibroblasts and other specialized connective tissue cells. The accumulation of HA on different tissues is a characteristic of disorders that are associated with progressive tissue fibrosis. HA is also known to play a critical role in tumorigenesis and tumor metastasis. It is overproduced by many types of tumors and promotes tumor progression and multidrug resistance. There is a great necessity for the development of an easy and cost-effective detection method for the monitoring of HA for both the diagnosis and efficient treatment of related disorders. In the present study, an innovative immune device was designed for the rapid and sensitive recognition of HA in human plasma samples. For this purpose, an efficient alloy (Pt@Au) was fabricated on the surface of the gold electrode. Thus, a novel substrate was used for the preparation of an efficient transducer, which is necessary for the immobilization of biotinylated antibodies. CHA was applied for the electrochemical deposition of Pt@Au nano-alloy on Au electrodes. Additionally, the morphological study of the used nanocomposite was assessed using FESEM at a working voltage of 3 kV, and the chemical structures of the electrode were analyzed using the EDS apparatus. For the first time, a biocompatible alloy-based substrate was prepared for the study of antigen–antibody identification. The developed immunosensor has a linear response within the range of 0.156–160 ng.mL−1 with a limit of detection of 0.039 ng.mL−1 in human plasma samples. This research study offers a novel promising technique for HA analyses and is anticipated to be used in the early diagnosis of some disorders related to abnormal levels of HA in human bio-fluids. Thus, a constructed (pt@Au) nano-alloy provides a useful interface for the dense loading of AB. This excellent design loads high sensations of the biosensor for the selective detection of HA in real samples (human bio-fluids).
Label-free immunosensing of telomerase using bio-conjugation of biotinylated antibody to poly(chitosan) gold nanoparticles Ahmad Mobed, Fereshteh Kohansal, Sanam Dolati, Mohammad Hasanzadeh Bioanalysis, 2023 Aim: This study aimed to establish a label-free electrochemical biosensor for telomerase detection in human biofluid. Method: Synthesized green nanocomposite (poly[chitosan] decorated by gold nanoparticles) was used for the efficient immobilization of biotinylated antibody of telomerase and immunocomplex of antigen-antibody. Poly(chitosan) was decorated by gold nanoparticles on the surface of a glassy carbon electrode using an electrochemical coating technique. Results: The constructed immunosensor exhibited wide dynamic range (0.078–160 IU/ml-1) with a low limit of quantification of 0.078 IU/ml-1, which present a unique manner for telomerase assays in early prognosis for cancers. Conclusion: This study encourages scientists and scholars to design and develop new biosensor platforms for point-of-care diagnostics for telomerase management, an interesting reference for future research.
