US Preventive Services Task Force
The United States Preventive Services Task Force (USPSTF) is "an independent panel of experts in primary care and prevention that systematically reviews the evidence of effectiveness and develops recommendations for clinical preventive services". The task force, a volunteer panel of primary care clinicians (including those from internal medicine, pediatrics, family medicine, obstetrics and gynecology, nursing, and psychology) with methodology experience including epidemiology, biostatistics, health services research, decision sciences, and health economics, is funded, staffed, and appointed by the U.S. Department of Health and Human Services' Agency for Healthcare Research and Quality. Intent The USPSTF evaluates scientific evidence to determine whether medical screenings, counseling, and preventive medications work for adults and children who have no symptoms. Methods The methods of evidence synthesis used by the Task Force have been described in detail. In 2007, their methods ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evidence-based Medicine
Evidence-based medicine (EBM) is "the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients". The aim of EBM is to integrate the experience of the clinician, the values of the patient, and the best available scientific information to guide decision-making about clinical management. The term was originally used to describe an approach to teaching the practice of medicine and improving decisions by individual physicians about individual patients. Background, history and definition Medicine has a long history of scientific inquiry about the prevention, diagnosis, and treatment of human disease. The concept of a controlled clinical trial was first described in 1662 by Jan Baptist van Helmont in reference to the practice of bloodletting. Wrote Van Helmont: The first published report describing the conduct and results of a controlled clinical trial was by James Lind, a Scottish naval surgeon who conducted re ...

American Cancer Society
The American Cancer Society (ACS) is a nationwide voluntary health organization dedicated to eliminating cancer. Established in 1913, the society is organized into six geographical regions of both medical and lay volunteers operating in more than 250 Regional offices throughout the United States. Its global headquarters is located in the American Cancer Society Center in Atlanta, Georgia. The ACS publishes the journals ''Cancer'', '' CA: A Cancer Journal for Clinicians'' and '' Cancer Cytopathology''. History The society was founded on May 22, 1913, by ten physicians and five businessmen in New York City under the name "American Society for the Control of Cancer" (ASCC). The current name was adopted in 1944. At the time of founding, it was not considered appropriate to mention the word "cancer" in public. Information concerning this illness was cloaked in a climate of fear and denial. Over 75,000 people died each year of cancer in just the United States. The top item on the fou ...

The federal government, sometimes simply referred to as Washington, is composed of three distinct branches: legislative, executive, and judicial, whose powers are vested by the U.S. Constitution in the Congress, the president and the federal courts, respectively. The powers and duties of these branches are further defined by acts of Congress, including the creation of executive departments and courts inferior to the Supreme Court. Naming The full name of the republic is "United States of America". No other name appears in the Constitution, and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prostate Cancer Screening
Prostate cancer screening is the screening process used to detect undiagnosed prostate cancer in men without signs or symptoms. When abnormal prostate tissue or cancer is found early, it may be easier to treat and cure, but it is unclear if early detection reduces mortality rates. Screening precedes a diagnosis and subsequent treatment. The digital rectal examination (DRE) is one screening tool, during which the prostate is manually assessed through the wall of the rectum. The second screening tool is the measurement of prostate-specific antigen (PSA) in the blood. The evidence remains insufficient to determine whether screening with PSA or DRE reduces mortality from prostate cancer. A 2013 Cochrane review concluded PSA screening results in "no statistically significant difference in prostate cancer-specific mortality...". The American studies were determined to have a high bias. European studies included in this review were of low bias and one reported "a significant reduction in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prostate-specific Antigen
Prostate-specific antigen (PSA), also known as gamma-seminoprotein or kallikrein-3 (KLK3), P-30 antigen, is a glycoprotein enzyme encoded in humans by the ''KLK3'' gene. PSA is a member of the kallikrein-related peptidase family and is secreted by the epithelial cells of the prostate gland. PSA is produced for the ejaculate, where it liquefies semen in the seminal coagulum and allows sperm to swim freely. It is also believed to be instrumental in dissolving cervical mucus, allowing the entry of sperm into the uterus. PSA is present in small quantities in the serum of men with healthy prostates, but is often elevated in the presence of prostate cancer or other prostate disorders. PSA is not uniquely an indicator of prostate cancer, but may also detect prostatitis or benign prostatic hyperplasia. Medical uses Prostate cancer Screening Clinical practice guidelines for prostate cancer screening vary and are controversial, in part due to uncertainty as to whether the benefits of ...

Politicization Of Science
The politicization of science for political gain occurs when government, business, or advocacy groups use legal or economic pressure to influence the findings of scientific research or the way it is disseminated, reported or interpreted. The politicization of science may also negatively affect academic and scientific freedom, and as a result it is considered taboo to mix politics with science. Historically, groups have conducted various campaigns to promote their interests in defiance of scientific consensus, and in an effort to manipulate public policy."Some bills seek to discredit evolution by emphasizing so-called "flaws" in the theory of evolution or "disagreements" within the scientific community. Others insist that teachers have absolute freedom within their classrooms and cannot be disciplined for teaching non-scientific "alternatives" to evolution. A number of bills require that students be taught to "critically analyze" evolution or to understand "the controversy." But th ...

Clinical Effectiveness
Efficacy is the ability to perform a task to a satisfactory or expected degree. The word comes from the same roots as ''effectiveness'', and it has often been used synonymously, although in pharmacology a distinction is now often made between efficacy and effectiveness. The word ''efficacy'' is used in pharmacology and medicine to refer both to the maximum response achievable from a pharmaceutical drug in research settings, and to the capacity for sufficient therapeutic effect or beneficial change in clinical settings. Pharmacology In pharmacology, efficacy () is the maximum response achievable from an applied or dosed agent, for instance, a small molecule drug. Intrinsic activity is a relative term for a drug's efficacy relative to a drug with the highest observed efficacy. It is a purely descriptive term that has little or no mechanistic interpretation. In order for a drug to have an effect, it needs to bind to its target, and then to affect the function of this target ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
