Tuskegee Syphilis Study
The Tuskegee Study of Untreated Syphilis in the Negro Male (informally referred to as the Tuskegee Experiment or Tuskegee Syphilis Study) was a study conducted between 1932 and 1972 by the United States Public Health Service (PHS) and the Centers for Disease Control and Prevention (CDC) on a group of nearly 400 African Americans with syphilis. The purpose of the study was to observe the effects of the disease when untreated, though by the end of the study medical advancements meant it was entirely treatable. The men were not informed of the nature of the experiment, and more than 100 died as a result. The Public Health Service started the study in 1932 in collaboration with Tuskegee University (then the Tuskegee Institute), a historically Black college in Alabama. In the study, investigators enrolled a total of 600 impoverished African-American sharecroppers from Macon County, Alabama. Of these men, 399 had latent syphilis, with a control group of 201 men who were not infected ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tuskegee, Alabama
Tuskegee () is a city in Macon County, Alabama, United States. It was founded and laid out in 1833 by General Thomas Simpson Woodward, a Creek War veteran under Andrew Jackson, and made the county seat that year. It was incorporated in 1843. It is the largest city in Macon County. At the 2020 census the population was 9,395, down from 9,865 in 2010 and 11,846 in 2000. Tuskegee has been important in African-American history and highly influential in United States history since the 19th century. Before the American Civil War, the area was developed for cotton plantations, dependent on enslaved African-American people. After the war, many freedmen continued to work on plantations in the rural area, which was devoted to agriculture, primarily cotton as a commodity crop. In 1881 the Tuskegee Normal School (now Tuskegee University, a historically black college) was founded by Lewis Adams, a former slave whose father, Jesse Adams, a white slave owner, had allowed him to be educat ...

Penicillin
Penicillins (P, PCN or PEN) are a group of β-lactam antibiotics originally obtained from ''Penicillium'' moulds, principally '' P. chrysogenum'' and '' P. rubens''. Most penicillins in clinical use are synthesised by P. chrysogenum using deep tank fermentation and then purified. A number of natural penicillins have been discovered, but only two purified compounds are in clinical use: penicillin G ( intramuscular or intravenous use) and penicillin V (given by mouth). Penicillins were among the first medications to be effective against many bacterial infections caused by staphylococci and streptococci. They are still widely used today for different bacterial infections, though many types of bacteria have developed resistance following extensive use. 10% of the population claims penicillin allergies but because the frequency of positive skin test results decreases by 10% with each year of avoidance, 90% of these patients can tolerate penicillin. Additionally, those w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cardiovascular System
The blood circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of a human or other vertebrate. It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek ''kardia'' meaning ''heart'', and from Latin ''vascula'' meaning ''vessels''). The circulatory system has two divisions, a systemic circulation or circuit, and a pulmonary circulation or circuit. Some sources use the terms ''cardiovascular system'' and ''vascular system'' interchangeably with the ''circulatory system''. The network of blood vessels are the great vessels of the heart including large elastic arteries, and large veins; other arteries, smaller arterioles, capillaries that join with venules (small veins), and other veins. The circulatory system is closed in vertebrates, which means that the blood never leaves the network of blood vessels. Some invertebrates such as ar ...

Prospective Study
A prospective cohort study is a longitudinal cohort study that follows over time a group of similar individuals ( cohorts) who differ with respect to certain factors under study, to determine how these factors affect rates of a certain outcome. For example, one might follow a cohort of middle-aged truck drivers who vary in terms of smoking habits, to test the hypothesis that the 20-year incidence rate of lung cancer will be highest among heavy smokers, followed by moderate smokers, and then nonsmokers. The prospective study is important for research on the etiology of diseases and disorders. The distinguishing feature of a prospective cohort study is that at the time that the investigators begin enrolling subjects and collecting baseline exposure information, none of the subjects have developed any of the outcomes of interest. After baseline information is collected, subjects in a prospective cohort study are then followed "longitudinally," i.e. over a period of time, usually for ...

Retrospective Study
A retrospective cohort study, also called a historic cohort study, is a longitudinal cohort study used in medical and psychological research. A cohort of individuals that share a common exposure factor is compared with another group of equivalent individuals not exposed to that factor, to determine the factor's influence on the incidence of a condition such as disease or death. Retrospective cohort studies have existed for approximately as long as prospective cohort studies. Design The retrospective cohort study compares groups of individuals who are alike in many ways but differ by a certain characteristic (for example, female nurses who smoke and ones who do not smoke) in terms of a particular outcome (such as lung cancer). Data on the relevant events for each individual (the form and time of exposure to a factor, the latent period, and the time of any subsequent occurrence of the outcome) are collected from existing records and can immediately be analyzed to determine the ...

Pathology
Pathology is the study of the causes and effects of disease or injury. The word ''pathology'' also refers to the study of disease in general, incorporating a wide range of biology research fields and medical practices. However, when used in the context of modern medical treatment, the term is often used in a narrower fashion to refer to processes and tests that fall within the contemporary medical field of "general pathology", an area which includes a number of distinct but inter-related medical specialties that diagnose disease, mostly through analysis of tissue, cell, and body fluid samples. Idiomatically, "a pathology" may also refer to the predicted or actual progression of particular diseases (as in the statement "the many different forms of cancer have diverse pathologies", in which case a more proper choice of word would be " pathophysiologies"), and the affix ''pathy'' is sometimes used to indicate a state of disease in cases of both physical ailment (as in card ...

Institutional Review Board
An institutional review board (IRB), also known as an independent ethics committee (IEC), ethical review board (ERB), or research ethics board (REB), is a committee that applies research ethics by reviewing the methods proposed for research to ensure that they are ethical. Such boards are formally designated to approve (or reject), monitor, and review biomedical and behavioral research involving humans. They often conduct some form of risk-benefit analysis in an attempt to determine whether or not research should be conducted. The purpose of the IRB is to assure that appropriate steps are taken to protect the rights and welfare of humans participating as subjects in a research study. Along with developed countries, many developing countries have established national, regional or local Institutional Review Boards in order to safeguard ethical conduct of research concerning both national and international norms, regulations or codes. A key goal of IRBs is to protect human su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Office For Human Research Protections
The Office for Human Research Protections (OHRP) is a small office within the United States Department of Health and Human Services (DHHS), specifically the Office of the Assistant Secretary for Health in the Office of the Secretary of DHHS, that deals with ethical oversights in clinical research conducted by the department, mostly through the National Institutes of Health (NIH). The office's primary duty is the implementation of , a set of regulations for Institutional Review Boards (IRBs) that mirrors the U.S. Food and Drug Administration (FDA) regulation that covers clinical research conducted by pharmaceutical companies as well as other regulations under the guidance of the Federal Policy for the Protection of Human Subjects, which is also known as the " Common Rule". Institutions that conduct DHHS-sponsored research must have a "Federal-Wide Assurance" (FWA), an agreement with OHRP regarding ethical oversight. OHRP also provides education for IRBs, gives guidance on researc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belmont Report
The ''Belmont Report'' is a report created by the National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research. Its full title is the ''Belmont Report: Ethical Principles and Guidelines for the Protection of Human Subjects of Research, Report of the National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research''. The report was issued on September 30, 1978 and published in the Federal Register on April 18, 1979. The report took its name from the Belmont Conference Center where the document was drafted in part. The Belmont Conference Center, once a part of the Smithsonian Institution, is in Elkridge, Maryland, 10 miles south of Baltimore, and until the end of 2010 was operated by Howard Community College. The ''Belmont Report'' summarizes ethical principles and guidelines for research involving human subjects. Three core principles are identified: respect for persons, beneficence, and justice.
