Screening and Early Detection for Colorectal Cancer Early detection and the removal of precancerous polyps can prevent the development of more than 50% of colorectal cancers (American College of Gastroenterology 2015). Screening is an integral part of preventing colorectal cancer. Screening is the process of looking for cancer or precancer in individuals who do not have symptoms of the disease. Physicians recommend that average-risk individuals get screened every 10 years starting at age 50.…

About HOSA Health Occupations Students of America, also known as HOSA, was established in 1976. HOSA is a student organization that has a goal of preparing students to enter the healthcare field. HOSA’s mission statement is to “Enhance the delivery of compassionate, quality healthcare by providing opportunities for knowledge, skill and leadership development of all health science technology education students, therefore, helping students to meet the needs of the healthcare community.” Members…

This case review involved a 19-year-old male football play who is currently a freshman in college. He came into the athletic training room complaining of right wrist pain. This athlete has had pain in this wrist for a couple of mouths and had only every taped the wrist two weeks prior to coming into the athletic training room for his first treatment. Even before coming in, he was able to do every drill or exercise at practice to completion. He only reported feeling pain during practice when he…

To diagnosis AS a transthoracic echocardiogram (TTE) is completed, with two dimensional doppler (2D). An Echocardiogram is a diagnostic study that uses ultrasound waves transmitted through a transducer using a conducting gel to create an image of the heart. Ultrasound waves are cyclic in nature and at a frequency that are not audible within the parameter of human hearing (Fridman, V., 2013). The transthoracic approach provides visualization of the heart and its structures. Throughout TTE the…

A mass is a lump that either your caregiver found during an examination or you found before seeing your caregiver. The colon is a major part of the large intestine. There are many possible reasons why a lump has appeared. Testing will help determine the cause and the steps to a solution. CAUSES Before complete testing is done, it may be difficult or impossible for your caregiver to know if the lump is truly in the colon or comes from one of the organs that are next to the colon. Problems in…

These sound pulses are usually in the order of 1-5 megahertz. The probe is a transducer that uses an array of piezoelectric crystals. When an electrical current from the machine is applied to these crystals, they rapidly change shape. The changes in shape cause vibrations of the crystals, producing ultrasound waves that travel outward…

Introduction: The use of electromyography (EMG) to monitor muscle tissue from surface skin provides important information about the components of electrical activity—namely motor unit (MU) activation—during a muscle contraction (Cashaback, Cluff & Potvin, 2013). Observing electrical activity of a muscle with EMG is a user friendly and non-invasive tool researchers use when investigating muscle physiology (Camata et al., 2009). EMG is commonly used to correlate EMG signal with fatigue by…

appears to be slightly more sensitive but less specific than MRI for detecting tendinosis and significantly more sensitive for detecting calcific tendonitis (Hodgson, O’Connor and Grainger, 2012). In addition, in ultrasound, operator experience and transducer frequency can markedly affect accuracy and it has an advantage over MRI because of the superior spatial resolution of ultrasound imaging (Hodgson, O’Connor and Grainger, 2012; Scott et…

Have you ever thought that one day you will be able to move a computer cursor, an artificial limb, or a mobile robot just by the power of your thoughts!? For normal people and people with disabilities like paralysis and limbs loss, this is a dream coming true. The goal of this research paper is to address the question of whether implantable devices can be the bright future of not only disabled people but also normal people. The paper also discusses the ethical concerns and the physical impacts…

The first and foremost procedure for this lab is to be familiarized with the lab equipment. The principle components to be interacted in this lab is the work station, the wind tunnel, the AOA adjusting handle, the airfoil with tufts, and the wind tunnel frequency controller. Switch the control mode for the tunnel frequency controller to be LOC or local of local control would be used instead of remote control. Make sure that the tubes are connected in a way such that the air and pressure should…
