Vascular Biology | Pulmonary, Allergy, Sleep & Critical …

Posted: Published on November 16th, 2018

Mission Statement: Pulmonary vascular disease is a growing problem in many systemic diseases. In disease states, such as systemic sclerosis and hemolytic anemias, in which patient survival has increased dramatically in recent years, pulmonary complications, especially vascular ones, have become the leading cause of morbidity and mortality. The mechanisms involved in development of pulmonary hypertension (PH) regardless of etiology is not well-understood. The object of our studies is to define pathogenic mechanisms, essential for the development of these vascular abnormalities and use them to try to direct new therapies. Lastly, each of these entities can be associated with relative or absolute hypoxemia; thus, we have been investigating the effects of hypoxia on pulmonary vascular endothelium and methods to mitigate its effect. The projects in our research group are linked by the underlying pulmonary vascular abnormalities they engender: Approximately 6-10% of adults with sickle cell disease have pulmonary hypertension which is an independent risk factor for mortality. We have been interested in studying genetic modulators of sickle cell disease that place patients at risk for the development of PH. We are in the process of performing genome wide association studies of the largest cohort of prospectively collected SCD patients with cardiopulmonary … Continue reading →

Pros and Cons of Stem Cell Research – The Balance

Posted: Published on November 16th, 2018

Debates over the ethics of embryonic stem cell research have divided scientists, politicians, and religious groups for years. However, promising developments in other areas of stem cell research have led to solutions that help bypass these ethical barriers and win more support from those against embryonic stem cell research; the newer methods don't require the destruction of blastocysts. In 1998, the first published research paper on the topic reported that stem cells could be taken from human embryos. Subsequent research led to the ability to maintain undifferentiated stem cell lines (pluripotent cells) and techniques for differentiating them into cells specific to various tissues and organs. The debates over the ethics of stem cell research began almost immediately in 1999, despite reports that stem cells cannot grow into complete organisms. In 20002001, governments worldwide were beginning to draft proposals and guidelines to control stem cell research and the handling of embryonic tissues and reach universal policies. The Canadian Institutes of Health Research (CIHR) drafted a list of recommendations for stem cell research in 2001. In the U.S., the Clinton administration drafted guidelines for stem cell research in 2000. Australia, Germany, the United Kingdom, and other countries followed suit and formulated their … Continue reading →

Spinal Cord Injury Types of Injury, Diagnosis and Treatment

Posted: Published on November 16th, 2018

According to the National Spinal Cord Injury Association, as many as 450,000 people in the U.S. are living with a spinal cord injury (SCI). Other organizations conservatively estimate this figure to be about 250,000. The spinal cord is about 18 inches long, extending from the base of the brain to near the waist. Many of the bundles of nerve fibers that make up the spinal cord itself contain upper motor neurons (UMNs). Spinal nerves that branch off the spinal cord at regular intervals in the neck and back contain lower motor neurons (LMNs). Types and Levels of SCI The severity of an injury depends on the part of the spinal cord that is affected. The higher the SCI on the vertebral column, or the closer it is to the brain, the more effect it has on how the body moves and what one can feel. More movement, feeling and voluntary control are generally present with injuries at lower levels. Tetraplegia (a.k.a. quadriplegia) results from injuries to the spinal cord in the cervical (neck) region, with associated loss of muscle strength in all four extremities. Paraplegia results from injuries to the spinal cord in the thoracic or lumbar areas, resulting in … Continue reading →

Heart Disease – Closer Look at Stem Cells

Posted: Published on November 15th, 2018

Cardiovascular disease is the number one cause of death worldwide in men, women and children, claiming more than 17 million lives each year. The effects of congestive heart failure and acute myocardial infarction (heart attack) present great challenges for doctors and researchers alike. In this section: Heart attacks cause damage to the heart muscle, making it less efficient at pumping blood throughout the circulatory system. Your heart is constructed of several types of cells. For mending damaged heart tissue, researchers generally focus on three specific heart cell types: Gladstone Institutes. Close up of a mouse heart stained to reveal the important structural protein that helps heart muscle cells to contract (red). The cell nuclei are labeled in magenta. Despite major advances in how heart disease is managed, heart disease is progressive. Once heart cells are damaged, they cannot be replaced efficiently, at least not as we understand the heart today. There is evidence that the heart has some repair capability, but that ability is limited and not yet well understood. Heart failure is a general term to describe a condition in which the hearts blood-pumping action is weaker than normal. How much weaker varies widely from person to person, but … Continue reading →

Heart Attack (Myocardial Infarction) Symptoms | Cleveland Clinic

Posted: Published on November 15th, 2018

What are the symptoms of a heart attack? If you are having any one of the symptoms described below that lasts for more than 5 minutes, SEEK EMERGENCY TREATMENT (CALL 911) WITHOUT DELAY. These symptoms could be the signs of a heart attack (also called myocardial infarction or MI) and immediate treatment is essential. Although most women and men report symptoms of chest pain with a heart attack, women are slightly more likely than men to report unusual symptoms. Those who have more vague or less typical "heart" symptoms have reported the following: In a multi-center study of 515 women who had an acute myocardial infarction (MI), the most frequently reported symptoms were unusual fatigue, sleep disturbances, shortness of breath, indigestion and anxiety. The majority of women (78%) reported at least one symptom for more than one month before their heart attack. Lessons learned: Some people have a heart attack without having any symptoms (a "silent" myocardial infarction). A silent MI can occur among all patients, though it is more common among women or people with diabetes. A silent MI may be diagnosed during a routine doctor's exam. If You Take Nitroglycerin If you have been prescribed nitroglycerin and you … Continue reading →

Myocardial Infarction (Heart Attack) Ischemia Pathophysiology, ECG, Nursing, Signs, Symptoms Part 1

Posted: Published on November 15th, 2018

Myocardial infarction (heart attack or MI) ischemia lecture on the pathophysiology, ECG, nursing role, complications, signs and symptoms. This video on myocardial infarction will help students prepare for the NCLEX exam. Myocardial infarction is when blood supplied to the heart muscle is limited which causes injury to the heart tissue. Injury from an MI causes complications such as pericarditis, cardiac rupture, cardiogenic shock, arrhythmias, ventricular aneurysm, heart failure, and depression. Signs of symptoms of an MI include: chest pain that radiates, is heavy/intense, and is not relieved by nitroglycerin or rest, nausea/vomiting, cold sweat, anxiety, increased heart rate or blood pressure, irregular heart rate. Tools used to diagnose a myocardial infarction include: cardiac markers (troponins, myoglobin, CK or CK-MB levels), EKG, echocardiogram, stress test with myocardial perfusion imaging, or heart catheterization. As the nurse it is important you know the basics about how to read an EKG during a possible myocardial infarction. You must know what areas of the leads reflect which heart wall and what type of EKG changes you are looking for: ST-segment depression or elevation, T-wave inversion or hyperacute, or pathological Q-wave.

Often called dermatitis, eczema can affect anyone in any age group. While there are good eczema treatments, there is no eczema cure. But what causes eczema? Everyday things in your environment cigarette smoke, pollen, and even your clothes can be what causes eczema to flare. This is a recurring, long-term inflammation of the skin thats related to sensitivity to allergens in the environment that may not cause the same rash in other people. There are two major types:atopicand contact eczema.Atopicis the most common form, and it's linked to asthma and hay fever (allergic rhinitis). Then there is contact eczema, in which something from the outside contacts the skin. Contact eczema can be allergic; for example, some people have a nickel allergy and they get eczema rashes from their belt, earrings, or other items. The second form of contact eczema is irritant, and it affects everyone to a certain degree. This is the type of eczema you may see from bandage adhesives, soaps, and detergentsand is commonly … Continue reading →
