CONSENT TO PARTICIPATE IN A RESEARCH STUDY

I. You are being asked to participate in a research study of respiratory illness among microwave popcorn and flavoring workers. The purpose of this study is to investigate the spectrum of lung disease occurring among flavoring-exposed workers.

II. The study will include the following:

A. Questionnaire: This will include questions about respiratory symptoms, work history, and health history. The questionnaire will be given by a NIOSH representative. This will take approximately 20 minutes.

B. Spirometry (breathing test): You will be asked to breathe in as deeply as you can and then forcefully blow out as quickly and completely as possible through a tube that you place in your mouth. You will be asked to do this at least 3 times, and possibly several more times. This test may be tiring, and you may feel momentary lightheadedness or chest discomfort. If, at any time, you feel unable to continue, the test will be terminated. This test takes about 10 minutes.

C. Bronchodilator test: Depending on the results of your spirometry test, you may be asked to inhale 4 puffs of a medicine that will open your airways if they are at all narrowed. After you have received this medication, you will be asked to blow in the spirometer again to see if your airways have responded. This medicine may make your heart beat fast or make you feel jittery for about 30 minutes. This test takes about 20 minutes.

Public reporting burden of this collection of information is estimated to average 10 minutes per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. An agency may not conduct or sponsor, and a person is not required to respond to a collection of information unless it displays a currently valid OMB control number. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden to CDC/ATSDR Reports Clearance Officer, 1600 Clifton Road NE, MS D-74, Atlanta, Georgia 30333; ATTN: PRA (0920-XXXX).

D. Diffusing capacity test: You will be asked to breathe in a harmless gas mixture containing helium and a very small amount of carbon monoxide, hold your breath for 10 seconds, and then breathe out. This will be repeated 2 or 3 times to measure how well your lungs transfer oxygen. You may feel momentary lightheadedness. This test takes about 20 minutes.

E. Total lung capacity: You will be asked to breathe oxygen that contains a tracer gas (nitrogen) through a tube. Then you will be asked to breathe regular air while the tracer gas (nitrogen) you breathe out is measured. You may experience a feeling of dryness in your mouth during inhalation. This test takes about 10 minutes.

F. High-resolution computed tomography (HRCT) of the chest: This is an X-ray test. You will be requested to wear a gown and remove metallic objects such as jewelry. You will be asked to lie down on the scanner table. You will then be asked to take a deep breath and hold it and then blow out. The test will take about 15 minutes.

This X-ray test exposes you to radiation. Radiation is a risk factor for cancer. The risk of cancer is related to radiation dose. The radiation dose you will receive during the scan is between 3 and 4 millisieverts (mSv). For comparison, the radiation dose associated with chest X-ray is 0.1 to 0.2 mSv, and the natural background radiation dose from sources in the environment is between 2 and 3 mSv per year.

G. Blood draw: You will be asked to provide a blood sample from a vein in your arm. We will draw 30 milliliters, or about six teaspoons, of blood that we will store frozen at NIOSH. The blood draw may cause mild discomfort, local swelling, and bruising at the blood draw site, and rarely fainting. The blood draw will take about 5 minutes. We may use this blood in the future for tests related to flavoring-related lung disease risk only. Some tests may reflect inflammation in the lungs. Other tests may be developed to see if you have genes related to how your body processes flavoring chemicals. If you give permission, this sample will be stored with a unique number so that we know it is yours and can link it with your other information. Once we know the specific blood tests we will be using in this study, we will contact you to describe the tests and ask for your written permission to perform the tests on your blood sample. We will also ask you at that time if you would like to receive a written copy of your blood test results. We will store this sample until the end of 2020 at which time the blood will be destroyed.

H. If you are pregnant or may be pregnant, you will not be allowed

To have the HRCT scan (section F) due to the potential risks of

radiation to the fetus. Although the diffusing capacity test (section D) is not specifically prohibited for pregnant women, out of an

abundance of caution, we will not administer this test to women

who are pregnant or may be pregnant.

III. Altogether, your participation in this study will take approximately 3 to 3.5 hours, which includes the time spent traveling and waiting for your tests. Transportation to and from the HRCT facility is free and will be by taxi service. You do not need to make any arrangements for the HRCT scan or the transportation to the radiology center.

IV. The benefits to you from participating include the free medical tests. NIOSH will provide you and your doctor (if you wish) with the results of your breathing tests and HRCT scan. One disadvantage, besides the slight discomfort and inconvenience described above, is that a test result may be outside the range of “normal” even though nothing is wrong. This could result in further medical evaluation that may not have been necessary.

V. These procedures are standard medical procedures (except for the possible blood tests as described above). For all but the HRCT scan, there are no alternative procedures. An alternative to the HRCT scan is a standard chest X-ray. However, HRCT scans have been found to be more effective in detecting lung disease than standard chest X-rays.

VI. Injury from participation is unlikely. However, if injury results, medical care is not provided, other than emergency treatment. If you are injured through negligence of a NIOSH employee you may be able to obtain compensation under Federal Law. If you want to file a claim against the Federal government, your contact point is: General Law Division of OGC Claims Office: (201) 233-0233. If you are injured through the negligence of a NIOSH contractor, your claim would be against the contractor, not the federal government. If an injury or harm should occur to you as the result of your participation, you should contact Rachel L. Bailey, DO, MPH, at (800) 232-2114 or Mark Toraason, PhD, (513) 533-8591, the chair of the NIOSH Institutional Review Board.

VII. If you have any reaction to the tests or procedures, you should contact Jean Cox-Ganser, PhD or Rachel Bailey, DO, at (800) 232-2114. You should also call Dr. Bailey if you have any questions concerning this study or your participation. If you have questions about your rights as a member of this research study, contact Mark Toraason, PhD, (513) 533-8591.

VIII. Your participation is voluntary, and you may withdraw your consent and your participation in this study at any time without penalty or loss of benefits to which you are otherwise entitled.

For your participation in one or more parts of the research study, you will receive a gift card to a local merchant for $50. Gift cards will be given at the completion of medical testing.

IX. USE OF INFORMATION

This study is being done by the National Institute for Occupational Safety and Health (NIOSH). NIOSH is part of the Centers for Disease Control and Prevention (CDC), a government agency in the Department of Health and Human Services. We collect this information in order to learn about various kinds of work hazards that may influence the health of the American worker.
