Inthe number of overdose deaths involving opioids was five times higher than in On average, Americans die every day from an opioid overdose.
Cellular cell phones first became widely available in the United States in the s, but their use has increased dramatically since then. Along with the large and still growing number of cell phone users both adults and childrenthe amount of time people spend on their phones has also risen sharply in recent decades.
Cell phones including smartphones give off a form of energy known as radiofrequency RF wavesso some concerns have been raised about the safety of cell phone use. With respect to cancer, concern focuses on whether cell phones might increase the risk of brain tumors or other tumors in the head and neck area.
How do cell phones work? Cell phones work by sending signals to and receiving them from nearby cell towers base stations using RF waves. This is a form of electromagnetic energy that falls between FM radio waves and microwaves.
Like FM radio waves, microwaves, visible light, and heat, RF waves are a form of non-ionizing radiation. RF waves are different from stronger ionizing types of radiation such as x-rays, gamma rays, and ultraviolet UV light, which can break the chemical bonds in DNA.
At very high levels, RF waves can heat up body tissues.
This is the basis for how microwave ovens work. But the levels of energy given off by cell phones are much lower, and are not enough to raise temperatures in the body.
How are people exposed? The RF waves from cell phones come from the antenna, which is part of the body of a hand-held phone.
The waves are strongest at the antenna and lose energy quickly as they travel away from the phone. The phone is typically held against the side of the head when in use. The body tissues closest to the phone absorb more energy than tissues farther away.
Many factors can affect the amount of RF energy to which a person is exposed, including: The amount of time the person is on the phone.
Whether or not the person is using the speaker mode on the phone or a hands-free device. Using one of these allows the phone to be held away from the head. The distance and path to the nearest cell phone tower. Cell phones adjust their power to use the minimum amount for a good signal.
Congratulations! You have taken your first step into the world of professional case management with the oldest and largest case management membership organization in the world. The Medical Services Advisory Committee (MSAC) is an independent non-statutory committee established by the Australian Government Minister for Health in Student Case Study Competition Tuesday, March 26, in Salt Lake City. This competition gives undergraduate and graduate students of health education the opportunity to display their developing expertise.
Being farther away from the tower requires more energy to get a good signal, as does being inside a building. The amount of cell phone traffic in the area at the time.Case Study Competition The Health Issue: The Centers for Disease Control and Prevention states that opioid-involved deaths continue to increase in the United States, and opioids are involved in the majority of drug overdose deaths (66%).
The case studies that follow were commissioned by the Secretary's Advisory Committee on Genetics, Health, and Society (SACGHS), US Department of Health and Human Services.

Fiber is a type of carbohydrate that the body can’t digest. Though most carbohydrates are broken down into sugar molecules, fiber cannot be broken down into sugar molecules, and instead it passes through the body undigested.
