Week 11 Class Notes Tuesday, 5 April 2016 Announcements: • Exam on Tuesday, 12 April (next Tuesday!) th th • In the event of the strike, Thursday (14 ) and Tuesday (19 ) will be cancelled • Research paper is due Thursday, 21 April I. Inherent Risk Factors (Ethnicity) a. Cancer Health Disparities i. Defined by the NCI as: 1. …differences in the incidences, prevalence, mortality, and burden of cancer and related adverse health conditions that exist among specific population groups in the United States ii. The American Cancer Society (ACS) defines these population groups in terms of: 1. Socioeconomic Status 2. Race/Ethnicity 3. Residence 4. Sex 5. Sexual orientation b. EXAMPLE: Health Disparities in Breast Cancer i. Caucasian women have higher breast cancer incidence ii. African American women have higher mortality rate iii. Discussion Point: What might explain these differences? 1. White women tend to have better access to health care in general before the cancer may develop a. Better preventative resources available on average II. Environmental Carcinogens a. Air Pollution i. Consists of solid particles and gasses in the air from car emissions, industrial pollutants, dust, pollen, etc ii. Exhaust from vehicles accounts for 30% of cancer risk from air pollutants 1. Ex: Benzene (known carcinogen) in vehicle emissions b. Air Pollution Globally i. Measurement: concentration of fine particulate matter in the air 1. Measurement instruments and scales vary widely 2. US: 18 ug/m^3 a. Micrograms per cubic meter of air 3. Concentration of fine particulate matter, that is particles smaller than 10 or 2.5 microns - called PM10 and PM2.5. 4. Average: 71 ug/m3 ii. Data released by WHO 1. Issues: some differences in measurement across countries a. (e.g: frequency and location) c. Air Pollution in China i. 98 ug/m^3 1. Data is unsure of where the number came from 2. It most likely is much higher III. Endocrine Disrupting Chemicals (EDCS): Bisphenol A (BPA) a. Found in numerous products, including baby bottles and food and beverage can liners b. Acts as a weak estrogen c. Linked to i. Breast cancer ii. Obesity iii. Early puberty iv. Diabetes d. 93% of Americans have BPA in their Urine e. Consumer concerns have led some companies to eliminate use of BPA, although safety profile of BPA substitutes is unknown f. Companies can label products BPA free, but there is usually still one or more products similar to it in the products g. BPA: Recommendations i. Reduce use od plastics 1. Substitute with glass ii. If you do use plastic, don’t heat it 1. BPA leaches into foods when plastic is heated h. Discussion Point: Difficult to establish link between environmental carcinogens and cancer. i. Why? 1. It’s hard to pinpoint a specific cause 2. Everyone has hundreds of behaviors a day 3. Hard to isolate or control for everything since humans are so complicated 4. We DO KNOW that eating right and exercising, and reducing sun exposure will decrease risk of cancer IV. Behavioral Risk Factors a. Cancer Risk Factors i. Lifestyle factors such as diet, physical activity, and smoking account for about 2/3 of all cancer deaths in the US b. Smoking i. Implicated cancers in 1. Kidney 2. Head 3. Neck 4. Lungs 5. And Leukemia ii. Men who smoke are 23.3x more likely to die from lung cancer than those who do not smoke c. UV Exposure i. Exposure to UVA and UVB radiation from the sun and tanning beds is the major cause of melanoma, squamous cell carcinoma, and basal cell carcinoma 1. Skin cancers are on the rise! ii. Total protection is also harmful 1. UVB facilitates production of vitamin D a. Recommendations: 5-10 minutes of sun exposure 3 times per week V. Protective Factors a. Protective Diets and Foods: Green Tea i. Green tea acts against cancer cells in cell cultures ii. Regular green tea though 1. Black tea is helpful; just not as effective iii. Acts as an ant-inflammatory, which slows cancer cell ability to spread iv. Clinical trial among early CLL leukemia patients found reduction in cancer cells v. Epidemiological findings are inconclusive b. Protective Diets and Food: Bottom Line i. Very difficult to isolate specific effects of specific food and nutrients ii. “Synergy of Foods” 1. How certain foods work together for benefits 2. Your best bet: Eat them all and incorporate into your everyday diet! Thursday 7 April 2016 ****** EXAM NEXT TUESDAY (4/12) ****** Tobacco Smoking I. Cigarettes a. Why so many additives? i. Over 500 additives 1. Range from coconut oil to ammonia 2. Many reasons a. Enhances taste b. Camouflage smoke ordor c. Enhance nicotine delivery d. Mask throat irritation i. And other symptoms caused by smoking ii. One significant issue is that while all these chemical compounds have been approved as additives to food, they were not tested by burning. iii. In 1984, the US Department of Health and Human Services began requiring tobacco companies to submit annually a confidential, aggregated list of ingredients added to cigarettes manufactured in or imported into the United States. In 1994, 1. National Public Radio reported on a number of these ingredients, which caused a public outcry. a. Subsequently, in that same year, the 6 major US tobacco companies made the list public. b. This was the only time the list was made public, and there is no current public list of tobacco additives. b. When burned, creates 4,000 compounds i. Anything that burns will produce a number of carcinogens 1. Marijuana smoking is not actually better due to still having the burning aspect ii. Over 60 carcinogens 1. Formaldehyde – linked to lung cancer 2. Arsenic – used in rat poison 3. Carbon Monoxide – linked to lung cancer 4. Benzene – linked to leukemia iii. Compounds found in cigarettes 1. Cadmium = Batteries 2. Stearic Acid = Candle Wax 3. Hexamine = Barbecue Lighter 4. Toluene = Industrial Solvent 5. Nicotine = Insecticide 6. Butane = Lighter Fluid 7. Acetic Acid = Vinegar 8. Methane = Sewer Gas 9. Arsenic = Poison 10. Carbon Monoxide = Car Exhaust 11. Methanol = Rocket Fuel 12. Ammonia = Toilet Cleaner 13. Paint c. What’s so addicting about them? i. Nicotine is addicting ii. Added chemicals may also increase addictive properties 1. E.G: Chemicals added to decrease metabolism of nicotine a. Ethanol is metabolized to acetaldehyde II. Nicotine a. Nicotine acts as a stimulant in moderate doses b. Binds to a particular type of acetylcholine receptor known as the nicotinic receptor c. Activates reward system i. Release of endorphins (endogenous opioids) and dopamine (among others) d. The main types of catecholamines (produced in brain and adrenal gland) are dopamine, norepinephrine, and epinephrine. e. Acetylcholine- in PNS, acetylcholine activates muscles, and is a major neurotransmitter in the autonomic nervous system. f. Decrease in the levels of monoamineoxidase (MAO), an enzyme responsible for breaking down dopamine (probably caused by some tobacco smoke ingredient other than nicotine, since nicotine itself does not dramatically alter MAO levels). g. Ever having smoked cigarettes was associated with a reduced risk of PD (odds ratio (OR) = 0.5, h. Nicotine produces rewarding effects by interacting with nAChRs on neurons in the brain’s mesolimbic reward system. i. Nicotine acts quickly on the brain i. 7 seconds j. Short half-life i. 40 minutes k. Withdrawal symptoms occur a few hours after last cigarette smoked Cigarette Smoking: Historical Roots and Prevalence I. Smoking in the US a. 21% = percentage of US adults who are current smokers i. Compared to 44% in 1966 b. Declines in smoking following 1964 i. Reported by the Surgeon General’s Report on Smoking c.

Indirect reference groups such as the media, considered secondary. iii. Modeling of smoking in the media (movies, t.v.) 1. Children who spend more time viewing movies which positively portray smoking, are more likely to take up smoking (Sargent et al, 2001). 2. Control variables? a. Controlled for numerous factors including age, sex, parent education, sensitive seeking, smoking by friends, family. ii. Once a teenager has begun using tobacco, experiences with the new behavior become increasingly important in whether or not the behavior persists, and observation of others’ use or non-use decreasingly so. 1. Experiences with tobacco serve to modify the youth’s definition of cigarette smoking, with positive experiences fostering more favorable attitudes. 2. Experiences with smoking also provide youth with first- hand information about rewards and punishments associated with tobacco use, including those that are social in nature and those that are internal to the person II.
