About this study

This crossover study is designed to compare the gastric layering and rates of emptying and by inference rates of digestion of two different porridge meals prepared from either finely milled or flaked oats. On each of two study days, a total of 9 MRI scans will be taken, I baseline and 8 post meal, to assess gastric layering and emptying over three hours. Blood samples will also be taken periodically over the same period in order to determine changes in concentrations of circulating glucose, insulin and key gastrointestinal hormones. Participants will also be asked to complete a questionnaire at predetermined times to assess feelings of satiation.

Read the detailed description

Eight participants will be recruited onto the study via the Human Nutrition Unit (HNU) Volunteer Database, advertising fliers and social media. Potential participants will be invited to IFR for a talk about the study, followed by health screening if they wish to participate. Written, informed consent will be taken by a member of the research team prior to undertaking any study related procedures.

Each participant will undergo 2 study days (min.7 days apart) and they will eat 2 types of porridge in a random order. Allocation of the order of the porridge meals will be done before the participants are recruited onto the study, using an online randomizer. On one occasion participants will consume porridge made from milled oats and on the other occasion porridge made from flaked oats. Participants will undergo 9 MRI scans of the stomach over a 3h post ingestion period, and after each scan a 4 ml blood sample will be collected via an intravenous cannula. Feelings of satiety will be assessed using a short VAS questionnaire at 9 intervals during the study day.

Study day participants will not be able to eat any food after 10.00pm on the evening prior to each study day, but they will be allowed water until they go to bed. Participants will be asked to record what they have eaten on the evening prior to study day 1, and they will be asked to eat the same foods on the evening before the second study day. Participants must not consume any breakfast on the morning of the study day, but they can drink up until 7 am. The study day will start at 9 am at the Radiology Department at the Norfolk and Norwich University Hospital. After cannulation and blood sampling, initial baseline MRI scans and VAS questionnaires, the participants will eat the allocated porridge (264 g) and drink the water provided (175 ml). They will then undergo 8 more MRI scans, have blood taken 8 more times and complete 8 satiety questionnaires at specific time points.

After completion of all MRI scans, blood sampling and satiety questionnaires, participants will be provided with a 500 ml bottle of water and a packed lunch.

What is being measured

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

  1. Volume of gastric content

    Three dimensional MRI data will be used to determine the volume of gastric content at each time point and thus allow the calculation of gastric emptying rate

    Measured: 3 hours

Secondary outcomes (1)
  1. Satiety response

    A visual analogue scale questionnaire will be used to assess satiety response at each time point.

    Measured: 3 hours

Questions about this trial

What is this clinical trial studying?

A study testing Flaked oats and Milled oats in people with Metabolic Syndrome, run by Quadram Institute Bioscience at 1 site in United Kingdom.

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 8 inclusion and 42 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 2 Sep 2016. 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 United Kingdom. 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?

Volume of gastric content (time frame: 3 hours). 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 2 Sep 2016.
