Filter by:It is known that Bisphenol-A (BPA) is the endocrine disrupting chemical that is most exposed by oral intake in daily life. Critical life periods when the sensitivity to these substances is known to be maximum; prenatal, postnatal and adolescence periods. The aim of this study is to compare the effects of plastic-free nutrition program, interactive education and BPA exposure feedback on urinary Bisphenol-A levels in adolescents with high use of packaged products.
Although the ban on indoor smoking has greatly reduced secondhand smoke (SHS) exposure in public spaces, the home environment is still the primary source of exposure to SHS, particularly in children under the age of five. Although attempts are often made to prevent or reduce children's exposure to SHS, such as education, counseling, and exposure feedback to parents, exposure remains. Although using materials such as brochures, messages, posters and reminders that will minimize the harms such as protecting children from SHS will reduce the exposure, exposure continues in the long term.The aim of this study is to compare the effect of giving exposure feedback to the parents according to the zero tolerance program (SToP) on the urinary cotinine level of the children. In this study with active control group, single-blind (participant), randomized control, stratified block randomization (1:1) will be performed. Totally 58 participants including STOP intervention group (n:29) and the exposure feedback group (n:29), which is the active control group, were planned to be included in the study, which was planned to be conducted between January and September 2023. Cotinine-sensitive dipstick test kits will be used for the primary outcome (urine cotinine). Cotinine-sensitive dipstick test kit is a simple, cost-effective test to determine smoking status. It is an easy-to-read test strip that can be used with either a saliva or a urine sample. Secondary outcomes will be evaluated by information form on exposure to second-hand smoke, an attitude form on exposure to second-hand smoke, and a scale of beliefs towards third-hand smoke. This protocol will demonstrate whether SToP interventions, a sustainable program for children at high risk of secondhand tobacco exposure, are a viable intervention for parents on how to reduce exposure.
The aim of this study is to investigate and possibly validate urinary biomarkers for prostate cancer. During this study the focus will be on aberrations of selected genes as prognostic or predictive value has been shown for these genes in tissue, CTC or blood derived cfDNA. Proteins will be explored in urine as well. This is a prospective study in which urine samples will be collected from healthy volunteers and urine samples and a blood sample from cancer patients with prostate cancer. The participants will be asked to provide a urine sample collected with the ColliPee® device and fill out an online questionnaire to collect usability data. Thereafter, the urine sample will be aliquoted to be used in the study to investigate the different urinary analytes.
The aim of this study is to evaluate and optimize protocols for the isolation and analysis of analytes in urine (cell-free nucleic acids, extracellular vesicles and proteins). The following factors will be evaluated (1) volumetric collection with Colli-Pee®, a collection device developed by Novosanis for standardized collection of urine, and (2) stabilization methods. This is a prospective study in which urine samples will be collected from healthy volunteers, urine samples and a blood sample from pregnant women and cancer patients with solid tumors with emphasis on breast- and prostate cancer. The participants will be asked to provide a urine sample collected with the Colli-Pee® device and fill out an online questionnaire to collect usability data. Thereafter, the urine sample will be aliquoted to be used in different pilot studies for the protocol optimization. For the pilot study where the effect of volume will be assessed, participants will be requested to collect multiple samples with different Colli-Pee® variants and fill out questionnaires accordingly.

Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and in infected patients, it produces symptoms which range from completely asymptomatic to those expressing severe illness. Early recognition of those developing severe manifestations allows for rapid and appropriate intervention, including admission to intensive care unit and intensive care therapy, such as mechanical ventilation. A current problem is that only limited data exist predicting the clinical course of COVID-19. This study will determine whether non-invasive urinalysis is useful in assessing and predicting the severity or clinical course of patients with COVID-19.
The goal of the overall CASUS project is to develop the first fully molecular integrated cervical cancer screening approach, based on first-void urine as an easily accessible and non-invasive source of biomarkers. In contrast to current screening modalities, the CASUS approach will identify women with clinically relevant disease in need of treatment using only a single sample that can be collected at home (one-step triage).

This study is part of the current global emergency scenario due to infection with Coronavirus, SARS-CoV-2 as indicated by the international taxonomy. Study aim is to investigate the possibility of the presence of the virus within the seminal fluid and in the urine of infected patients, both during the acute phase and remotely. Current evidences show that Coronaviruses can be present inside the testicle and sperm in other species, such as in feline and avian models. In human beings, current researches have mixed results regarding the presence of SARSCoV-2 in urine, as several studies with a large sample found no traces of the same with Real-Time Reverse method Transcriptase - Polymerase Chain Reaction or with method of nucleic acid amplification. By contrast, in just over 6% of 58 patients with Real Time Polymerase Chain Reaction method have found the presence of SARS-CoV-2 in the urine, even at a distance from the last negative nasopharyngeal swab. Given the topicality of the problem, our study has the objective of specifically researching the presence and possible persistence over time of SARS-CoV-2 in seminal fluid and urine. A saliva sample will also be collected as a control. At the moment there are no studies in literature that tested this possibility. If confirmed, it would lead to find out another potential method of transmission, the sexual one, in asymptomatic patients or apparently no longer infectious with negative buffer. The rationale for our study is the evidence that in other species this type of transmission by coronaviruses is possible and that at present it has not been verified in mankind. The relevance of the study would be both in the case of a negative result, as the first study in its generally, both in the case of a positive result, due to the possibility of introducing new prevention measures in the long run.
DNA biomarkers in urine are important diagnostic and prognostic indicators for bladder cancer. Many genetic alterations have been identified in the urinary DNA. However, not all bladder tumors harbor mutations in the most commonly altered oncogenes. Thus, to reach satisfactory sensitivity and specificity a new diagnostic test should include multiple biomarkers. The investigators will conduct a prospective evaluation of a panel of mutations in urine-DNA test for the detection of urothelial bladder carcinoma in patients with gross hematuria for cystoscope.
