    Objective: This research aims to (i) examine the effects of nutrition on urine biochemistry and (ii) compare the two different measurement methods (laboratory and commercial strip). This means it is desired to bring a new direction to the literature. Methods: The study involved 42 women aged 20-30 from Turkey and examined the urinary excretion of calcium, vitamin C (smoker and non-smoker), sodium, and magnesium based on nutritional status. The collected urine samples were applied onto commercial urine strips, and the resulting color changes were recorded by smartphone; at the same time, it was sent to the laboratory for comparative analysis. The obtained data were used in regression and correlation statistical analysis. All statistical analyzes were performed using IBM SPSS 28.0. Results: While evaluating the regression analysis results in which the excretion due to nutrition was examined, each nutritional level was compared to the restricted intake. ANOVA sig values <.001, t values 1.96 <, in all metabolites (calcium, vitamin C, sodium, magnesium) evaluations. The following rates (R2 values) were obtained restricted/optimal nutrition in calcium, vitamin C, sodium, and magnesium: .636, .575, .386, and .209 respectively; restricted/high nutrition in calcium, vitamin C (non-smoker), vitamin C (smoker), sodium, magnesium: .442, .308, .482,.413 and .337 respectively; restricted/supplement in calcium, vitamin C, magnesium: .273, .698 and .799. Calcium and magnesium strips correlated strongly with lab results, correlation coefficients are .679 and .59 respectively. Sodium and creatinine strips correlated very strongly with lab results, correlation coefficients are .876 and .884 respectively. Conclusion: The study revealed that nutrition significantly affected urine excretion levels for calcium, vitamin C, sodium, and magnesium. Additionally, the results showed that urine strips had a correlation with laboratory results indicating their usefulness for pre-diagnosis purposes.

    Innovative biosensor technologies in the diagnosis of urinary tract infections: a comprehensive literature review
    (Springer, 2024) Çelik, Haluk; Caf, Balım Bengisu; Çebi, Gizem
    Urinary tract infections (UTIs) are prevalent bacterial infections globally, posing significant challenges due to their frequency, recurrence, and antibiotic resistance. This review delves into the advancements in UTI diagnostics over the past decade, particularly focusing on the development of biosensor technologies. The emergence of biosensors, including microfluidic, optical, electrochemical, immunosensors, and nanotechnology-based sensors, offers enhanced diagnostic accuracy, reduced healthcare costs. Despite these advancements, challenges such as technical limitations, the need for cross-population validation, and economic barriers for widespread implementation persist. The integration of artificial intelligence and smart devices in UTI diagnostics, highlighting the innovative approaches and their implications for patient care. The article envisions a future where multidisciplinary research and innovation overcome current obstacles, fully leveraging the potential of biosensor technologies to transform biosensor-based UTIs diagnosis. The ultimate goal is to achieve rapid, accurate, and non-invasive diagnostics, making healthcare more accessible and effective.

    Smartphone-Based Point-of-Care Urinalysis Vivoo App: A Validation Study
    (International Society of Academicians, 15 Nisan 2024) Caf, Balım Bengisu; Çebi, Gizem; Çelik, Haluk; Noroozi, Aliasghar; Atasever, Ali; Tayfun, Miray
    Point-of-care (POC) analysis has emerged as a pivotal approach in providing rapid and convenient medical diagnostics. Smartphone-based solutions further augment the accessibility and ease of POC, enabling efficient on-the-go analysis. The integration of smartphone technology with POC has paved the way for innovative applications such as the Vivoo App, which empowers users to monitor various health parameters conveniently. Our study validated the accuracy and reliability of the smartphone-based POC urinalysis Vivoo mobile application. A comparative approach was followed wherein artificial urine samples were analyzed using both the Vivoo and traditional laboratory methods. A diverse range of health parameters were assessed. A total of 2618 strips were used over the course of this study to evalate the accuracy of Vivoo. The test strips results appeared to match exactly the expected measurement results. In addition, when the ±1 color block acceptance criterion was applied, 2608 of 2618 measurements of the tested strips were found to have met the expected measurement results completely. Based on the results, the 95% confidence interval for the exact match agreement proportion of Vivoo is 87.55% ± 1.27% and 99.62% ± 0.24%. As a wellness product, this study thus concludes that the Vivoo is appropriate in terms of both device reliability and performance. The app's ability to provide accurate and timely health results offers promising opportunities to improve individual health management.
