What are 3 structural and behavioral characteristics that might confer selective advantages to human

This Education Dive article provides a brief overview of a new report from Georgia Tech that considers five initiatives to address the higher education needs of students in The author notes other reports and writers who have addressed one or more of these topics.

What are 3 structural and behavioral characteristics that might confer selective advantages to human

The medical literature does not support the utility of the above tests for screening, diagnosis, or management of CHD. Homocysteine Testing Aetna considers homocysteine testing experimental and investigational for assessing CHD or stroke risk and for evaluating women with recurrent pregnancy loss see CPB - Recurrent Pregnancy Loss.


Homocysteine testing may be medically necessary for the following indications: Measurement of Carotid Intima-media thickness Aetna considers measurement of carotid intima-media thickness experimental and investigational for assessing CHD risk because its effectiveness has not been established.

Noninvasive Measurement of Arterial Elasticity Aetna considers noninvasive measurements of arterial elasticity by means of blood pressure waveforms e. Peripheral Arterial Tonometry Aetna considers peripheral arterial tonometry e.

The Corus CAD is considered experimental and investigational for all other indications.

Understanding Evolution: History, Theory, Evidence, and Implictions

Stress Echocardiography Aetna considers stress echocardiography experimental and investigational for cardiovascular disease risk assessment in asymptomatic low risk individuals.

Venous Ultrasound Aetna considers venous ultrasound experimental and investigational for screening of persons without signs or symptoms of peripheral venous disease. Background Cardiovascular disease CVD risk testing is utilized to indicate the chances of having a coronary event.

The most common tests to determine cardiac risk are high-density lipoprotein HDLlow-density lipoprotein LDLtotal cholesterol and triglycerides often referred to as a basic or standard lipid panel.

Non-traditional risk factors for coronary heart disease CHD are used increasingly to determine patient risk, in part because of an assumption that many patients with CHD lack traditional risk factors e.

The authors conclude that current evidence does not support the notion that non-traditional risk assessment adds overall value to traditional risk assessment.


Follow-up ranged from 21 to 30 years. The assessment explained that the strongest evidence of the value of such a test is direct evidence that its measurement to assess cardiovascular disease risk results in improved patient outcomes.

In the absence of such evidence, the assessment of the potential clinical utility of a test lies in understanding a chain of logic and the evidence supporting those links in the chain. The potential for clinical utility of a test for assessing cardiovascular disease risk lies in following a chain of logic that relies on evidence regarding the ability of a measurement to predict cardiovascular disease beyond that of current risk prediction methods or models, and evidence regarding the utility of risk prediction to treatment of cardiovascular disease.

In order to assess the utility of a test in risk prediction, specific recommendations regarding patient management based on the test results should be stated. In a report on the use of non-traditional risk factors in CHD risk assessment, the U. Treatment to prevent CHD events by modifying risk factors is currently based on the Framingham risk model.

Risk factors not currently part of the Framingham model i. They said there is insufficient evidence to determine the percentage of intermediate-risk individuals who would be re-classified by screening with non-traditional risk factors, other than hs-CRP and ABI.

For individuals re-classified as high-risk on the basis of hs-CRP or ABI scores, data are not available to determine whether they benefit from additional treatments.

In addition, there is not enough information available about the benefits and harms of using non-traditional risk factors in screening.

Potential harms include lifelong use of medications without proven benefit and psychological and other harms from being mis-classified in a higher risk category. An elevated CRP level may be indicative of inflammation nonspecific location. It has been theorized that certain markers of inflammation -- both systemic and local -- may play a role in the development of atherosclerosis.

Of current inflammatory markers identified, hs-CRP has the analyte and assay characteristics most conducive for use in practice.

For these patients, the results of hs-CRP testing may help guide considerations of further evaluation e. The Writing Group noted, however, that the benefits of such therapy based on this strategy remain uncertain. The Writing Group stated that hs-CRP also may be useful in estimating prognosis in patients who need secondary preventive care, such as those with stable coronary disease or acute coronary syndromes and those who have underdone percutaneous coronary interventions.

The Writing Group posited that this information may be useful in patient counseling because it offers motivation to comply with proven secondary preventive interventions. However, the Writing Group noted that the utility of hs-CRP in secondary prevention is more limited because current guidelines for secondary prevention generally recommend, without measuring hs-CRP, the aggressive application of secondary preventive interventions.The MacArthur Foundation Research Network on Law and Neuroscience.
