About this study

Official title: Investigation of Nicotine in Umbilical Cord Tissue: Immunohistochemical and Biochemical Analysis of Cancer Stem Cell Markers

The umbilical cord is generally an organ that clinicians and pathologists do not pay sufficient attention to. The absence of significant pathology in the umbilical cords, along with the lack of association between certain placental pathologies and perinatal mortality and morbidity, have led both clinicians and pathologists to inadequately evaluate the placenta and umbilical cord. In our study, İnvestigators aimed to perform immunohistochemical and biochemical analysis by comparing two groups, one consisting of women who smoked throughout their pregnancy and the other of those who never smoked, including different markers in accordance with the literature.

Method: The pregnant women included in the study were categorized according to their smoking status as follows:

Group I: Non-smokers (smoking -) Group II: Smokers (smoking +) during pre-pregnancy and throughout the pregnancy In this study, 40 pregnant women who smoked during their pregnancy (between 37 and 42 weeks of gestation) and 37 age- and parity-matched healthy non-smoking pregnant women with full-term births between 37 and 42 weeks of gestation were selected as the control group. Umbilical cord samples (2 ml of blood and a 5 cm tissue sample) were collected from both groups without delay and fixed in 10% formalin. The tissue samples were processed for histological analysis with routine hematoxylin and eosin (H\&E) staining following fixation in 10% formalin solution and routine paraffin embedding.

İnvestigators aimed to examine the presence of oncological factors such as CD44, CD34, CD90, and ALDH molecules in the umbilical cord tissue of smokers during pregnancy through immunohistochemistry, and to explore the biochemical relationship of these molecules with their counterparts, CD34, CD44, CD90, and ALDH, found in the umbilical cord blood.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Hospitalized pregnant women's with smokers and nonsmokers 80%umblical cord tissues 3x3 cm collected while birth during the study .umblical tissues staining will be Measured by Cd34, Cd44, Cd90 and ALDH immunohistochemistry technique.

    Measured: Baseline

  2. Hospitalized pregnant women's with smokers and nonsmokers 80% umblical blood 5-7 ml collected while birth during the study. Bloods will be measured by Cd34, Cd44, Cd90 and ALDH biochemistry elisa technique.

    Measured: Baseline

Questions about this trial

What is this clinical trial studying?

An observational study of Umbilical Cord Issue and Nicotine Addiction, run by Manisa Celal Bayar University at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 27 Jan 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Hospitalized pregnant women's with smokers and nonsmokers 80%umblical cord tissues 3x3 cm collected while birth during the study .umblical tissues staining will be Measured by Cd34, Cd44, Cd90 and ALDH immunohistochemistry technique. (time frame: Baseline). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jan 2025.
