y of a given clinical test refers to the ability of a test to accurately classify those patients with disease while specificity refers to the ability of the test to correctly identify patients without the disease. Consequently, Lovallo et al (2010) noted that specificity and sensitivity are inversely related in that the higher the sensitivity in a test, the lower the specificity of the same test. Therefore, a test having high sensitivity and lower specificity will accurately indicate higher percentage of patients as having a disease while limitedly identifying patients without the disease. Therefore, the use of high sensitivity and lower specificity is best suited in screening a severe but curable disease. On the contrary, the second test with a high specificity and low sensitivity will accurately identify higher percentage of patients without the diseases but inadequately provide information on those patients suffering from the diseases.
Therefore, in the case of a deadly disease that is curable, it is essential that clinical tests apply the first test since it will accurately identify a higher percentage of patients having the disease and hence facilitate mitigation of the disease. Prompt and accurate identification of individuals suffering from the disease will enable early detection and issuance of medical treatment. The screening process should hence apply test one.

The increasing ethnic diversity in the United States has caught the attention of the healthcare community. Cultural differences affect how individuals access health care. Cultural disparities that exist between the healthcare recipients and providers have led to problems including unsatisfactory results, wrong diagnostics, and now patients are keener.
Ventilator acquired pneumonia (VAP) is pneumonia that occurs in patients on endotracheal intubation or tracheostomy tube after 48 hours or more which was not originally present before the ventilation. It is the most common ICU infection and the most fatal of all.
In the writing of this paper the subject was to mimic the style of the scientific article as closely as possible. A short list of changes made to the APA style of writing includes the title, lack of a title page, and numbered references. The style of writing in all of these articles appears to mimic that of major journal articles presenting data on the subject up front and following with the methodology.
Magnetic resonance Imaging involves the use of powerful magnetic fields and radio frequencies to produce computerized and detailed images of soft tissues, organs and bones, as well as any other internal body structure. Unlike some imaging techniques, such as X-ray or computed tomography, MRI does not require the use of ionizing radiation.
Antigens introduced into the tissue will bind to labeled antibodies acting as specially designed reagents, and this technique allows one to assess the presence of specific antigen or protein. This binding event is visualized and examined under a microscope
An approval from a Research Ethics Committee as well as Research Governance approval were not obtained as the researcher does not plan to do further testing. Besides, all the results for the use of this study were gathered from routine tests.
The confirmed approval for the Project Proposal rests with the University, and such approval cannot be used in other situations (eg for a Research Ethics Committee etc.) without the permission of the University, via the relevant etutor, or for full-time students, their academic supervisor.
