Safyral Side Effect News:

Before a prothrombotic state is sought in patients with recurrent pregnancy loss, structural, cytogenetic, and endocrinological abnormalities should be ruled out. If no other cause for the pregnancy loss can be discerned, an antiphospholipid antibody should be sought. It remains controversial whether other causes of a prothrombotic condition should be investigated such as the factor V Leiden muta­tion, the prothrombin gene mutation, or hyperhomocysteinemia.

There are many published reports of strategies used for the prevention of fetal loss in patients with APS. However, only a few present data derived from well- designed and executed clinical trials. To provide the most rigorous possible con­clusions, we have limited this review to treatment recommendations derived from studies in which all patients had a persistently positive antiphospholipid antibody and two or more first-trimester pregnancy losses or one or more second- or third- trimester losses. We excluded studies including patients with secondary APLA, such as those with SLE, to eliminate confounding effects of the underlying dis­ease on the likelihood of successful pregnancy outcome, and we excluded nonran­domized studies with less than 10 patients because of the potential for bias in these small case series.

One recently reported study is relevant to this review, but is not included in the analysis because it did not satisfy the inclusion criteria. The randomized controlled trial published by the Pregnancy Loss Study Group (59) enrolled 16 patients, 9 of whom received heparin and ASA, and 7 of whom received heparin, ASA, and IVIG administered in a dose of 2 g/kg monthly from documentation of pregnancy until 36 weeks gestation. All 16 patients enrolled in this study delivered successfully. However, it was not clear whether the antiphospholipid antibody titer was confirmed on at least two occasions.

Low-molecular-weight heparins are an attractive alternative to standard heparin for many indications because, in animal models, they produce less osteo­porosis than standard heparin, yet they appear to be at least as effective as standard heparin. This suggests that low-molecular-weight heparins would be an excellent choice for anticoagulation during pregnancy. However, until good-quality evidence exists for the effectiveness of the low-molecular- weight heparins in patients with an antiphospholipid antibody and recurrent preg­nancy loss, their routine use cannot be recommended.

In summary, based on currently available literature, it appears that the treat­ment of choice for the prevention of pregnancy loss in women with APS is low- dose heparin and aspirin. Although we cannot confidently exclude the possibility that prednisone plus ASA therapy is as, or more, effective than heparin plus aspirin therapy, prednisone-containing regimens are associated with a higher risk of maternal and obstetric toxicity. In addition, based on our analysis, we conclude that rigorous clinical trials designed to determine the optimal type and duration of treatment to enhance the likelihood of live birth are urgently needed.

Safyral Side Effect : As with all other areas in this field, there remain many unanswered questions. Although one small study suggests that low-dose unfractionated heparin increases the likelihood of successful pregnancy outcome, there are no independent, ran­domized studies to support this conclusion. Low-molecular-weight heparins have replaced unfractionated heparin in many clinical circumstances; whether low- molecular-weight heparin can replace unfractionated heparin in this patient popu­lation has never been tested in a randomized clinical trial. Aspirin therapy is widely accepted in this patient population, yet its efficacy has never been proven in a methodologically rigorous study. Finally, the role of anticoagulants or immu­nosuppressant therapy has never been tested in women who are unable to con- cieve, or those with pregnancy loss at less than 8 weeks gestation.

Furthermore, the response of patients with anti­phospholipid antibody-associated thrombocytopenia to immunomodulatory therapy supports the hypothesis that the thrombocytopenia is due to immune plate­let destruction. No large prospective studies of therapy for antiphospholipid anti­body-associated thrombocytopenia have been reported. However, based on anec­dotal experience, therapy with corticosteroids, intravenous immunoglobulin, immunosuppressive agents, and, ultimately, splenectomy for patients with severe, refractory thrombocytopenia may be effective. Galindo and colleagues re­ported their experience with 11 patients who underwent splenectomy for severe, refractory thrombocytopenia. Nine patients had a good clinical response, as de­fined by platelet counts in excess of 100 X 10⁹/L without pharmacological ther­apy. Many patients with immune platelet destruction will have markedly low platelet counts (30 to 50 X 10⁹) yet be asymptomatic; such patients are best treated with careful monitoring, rather than potentially toxic interventions. If therapy for thrombocytopenia is required, platelet counts can usually be temporarily increased with corticosteroids or intravenous immunoglobulin.

Considerable evidence supports a relation between postmenopausal hormone therapy and cardiovascular disease. Specifically, long-term use of hormone ther­apy is associated with substantial protection against heart disease. This protection, observed largely in observational epidemiological studies, may be due, in part, to self-selection bias. Women who take hormones may not be completely compa­rable to those who do not; women on hormone therapy see a physician regularly and may lead generally healthier lifestyles. However, adjustment for known car­diac risk factors in many of the large studies of homogeneous populations had little impact on their results, implying an equivalent risk status for users and nonusers. To date, however, no randomized trial data in primary prevention have been presented. The effect of progestin added to estrogen therapy has not been adequately assessed, but initial evidence suggests that most of the coronary bene­fit is probably retained. Considerable controversy exists regarding the effect of hormones in women with established coronary disease, although, like the studies of primary prevention, existing data suggest long-term benefits. On the other hand, the only randomized trial in secondary prevention, the HERS study, failed to show the expected benefits of this approach over a 4-year period of observation.

Cardiovascular diseases (CVD) remain the leading cause of death in women. The role of hormone therapy in CVD remains a controversial topic, de­spite clear evidence from randomized clinical trials that hormone use improves the lipid profile, enhances blood flow, and has numerous other beneficial effects on intermediate endpoints. This chapter summarizes the epidemiological investi­gations regarding the association between postmenopausal hormone therapy and cardiovascular disease, including primary and secondary prevention of coronary heart disease, stroke, and pulmonary embolism. For coronary heart disease, sub­stantial evidence on primary prevention has accumulated from numerous observa­tional studies. Less consistent information is available on the relationship between stroke and hormone therapy. Finally, few studies have examined the relation of hormone use to second coronary events or to pulmonary embolism, but the only completed large-scale clinical trial of hormone therapy addresses these issues.

Safyral Side Effect : Overwhelming evidence from epidemiological studies indicates an inverse rela­tion between hormone use and heart disease in healthy women. Several observa­tional study designs have been used to examine this association: hospital and community-based case-control studies; cross-sectional studies; and prospective studies; virtually all report a lower risk of heart disease for women who take hormones than those who do not. In addition, results from all the studies have been combined in several meta-analyses, with summary relative risk esti­mates in all these indicating approximately a 35% lower rate of coronary heart disease (CHD) for hormone users than nonusers. However, many studies suggest that current hormone users enjoy greater protection against heart disease than past users. Thus, combining investigations of current, past, and ever use in a summary estimate is misleading because the results will be directly affected by the proportion of past and current use in the studies included. As expected, summary estimates based on analyses of current use are lower than those derived by combining studies of any hormone use. For all studies of current use.

Of the studies included in the meta-analyses, the Nurses’ Health Study is the largest prospective cohort to investigate hormone use and heart disease. The study was established in 1976 when 121,700 married female registered nurses aged 30 to 55 years completed a mailed questionnaire. Information on coronary risk factors and hormone use was updated with follow-up questionnaires sent every 2 years. Reports of coronary disease are confirmed by medical record review, and data on hormones and other possible risk factors are likely to be reliable since all subjects are registered nurses, with a demonstrated interest in medical research. In the analysis of hormones and heart disease, a total of 70,543 postmenopausal women without prior coronary heart disease were followed for up to 20 years; 945 nonfatal myocardial infarctions and 186 confirmed coronary deaths were documented.

Preliminary data released from the Women’s Health Initiative, an ongoing, large randomized clinical trial of hormone therapy and cardiovascular disease in healthy women, suggested that there may be a slight rise in the risk of heart disease, stroke, and venous thrombosis during the initial 1 to 2 years of hormone use, followed by a decrease in risk with continued use. Unfortunately, there is very little additional evidence available on this issue; most of the observational studies mentioned above primarily consist of long-term hormone users, and very few investigations have specifically examined the short-term effects of hormone therapy on CVD. In the Leisure World Study, a large prospective observa­tional cohort, the relative risk of CHD was 0.73 (95% CI, 0.46-1.16) for recent hormone users of 3 or fewer years duration compared to nonusers; although this estimate of duration was based on a single assessment of hormone use at baseline. In the Nurses’ Health Study, current hormone users of less than 2 years had a relative risk of CHD of 0.53 (95% CI, 0.31-0.93); but, since information is collected biennially, the actual duration of use would be underestimated.

In a small prospective study, Avilaetal found little relation between less than 1 year of current hormone use (RR = 0.9; 95% CI, 0.4-1.9) and MI. In case-control studies, Sidney etal observed no association between current hormone use of less than 1 year and MI (RR = 0.95; 95% CI, 0.37-2.45), and Heckbert also reported that current hormone use of less than 1.8 years was not related to myocardial infarction (RR = 0.91; 95% CI, 0.60-1.38). In the latter study, there was a trend of decreasing risk of MI with increasing duration of hormone use (RR = 0.55; 9% CI, 0.34-0.88 for 8.2 years or more), similar to that reported in the information released by the Women’s Health Initiative. Clearly additional data are necessary.

Safyral Side Effect : Currently, progestins are prescribed along with estrogen in women with a uterus to reduce or eliminate the excess risk of endometrial cancer due to unopposed estrogen. However, progestin use was quite uncommon during the period that most of the epidemiological studies were conducted. Hence, most of the data are related directly to use of estrogen alone. In studies of intermediate endpoints, randomized clinical trials report significant decreases in LDL and increases in HDL for women assigned to estrogen combined with progestin, but for HDL, the elevation among users of estrogen with medroxyprogesterone acetate (the most commonly used progestin in the U.S.) is significantly less than that for users of estrogen alone. In addition, while estrogen therapy improves blood flow, limited studies suggest that this benefit may be diminished with the addition of progestin. Thus, progestin might be hypothesized to detract from the overall bene­ficial effects of estrogen on heart disease.

Nonetheless, in the few observational epidemiological studies of primary prevention which separately examine combined hormone therapy, virtually all strongly suggest a similar impact of estrogen combined with progestin and estro­gen alone. In a follow-up study in Uppsala, Sweden, the relative risk of MI was 0.64 (95% CI, 0.45-0.90) for women taking estrogen with progestin. In the Nurses’ Health Study, the relation of hormone use to CHD was similar for users of estrogen alone (RR = 0.56; 95% CI, 0.46-0.68) and estrogen com­bined with progestin (RR = 0.66; 95% CI, 0.49-0.87), after adjusting for an array of coronary risk factors.

Although limited data are available regarding hormone therapy and secondary prevention of CHD, the only published, large-scale randomized clinical trial on hormones and CVD included only women with established CHD. The Heart and Estrogen/progestin Replacement Study (HERS) (10) randomized 2763 women with coronary disease to 0.625 mg of oral conjugated estrogen combined with 2.5 mg of continuous medroxyprogesterone acetate (n = 1380) or placebo (n = 1383). Surprisingly, there was no overall protection against second coronary events for women assigned to treatment, compared to those given placebo (RR = 0.99; 95% CI, 0.80-1.22). However, as also suggested by the preliminary results released from the Women’s Health Initiative, there was a strong trend of decreas­ing risk of heart disease with increasing duration of hormone use (p-trend = 0.009). In the first year of the trial, the risk of major coronary disease increased 52% among treated women; in the second year, there was no relation between treatment and disease (RR = 1.00), and in the third year the relative risk was 0.87.

Recent data from the Nurses’ Health Study report similar results to the HERS trial. Among 2489 postmenopausal participants with previous coronary disease, we identified 213 cases of recurrent nonfatal myocardial infarctions or coronary deaths. We also observed a trend of decreasing risk of recurrent events with increasing time since initiation of current hormone use (p-trend = 0.002). For users of less than 1 year, the multivariate-adjusted relative risk of major CHD was 1.25 (95% CI, 0.78-2.00), compared to never users. After 2 or more years since beginning hormone use, we found a significantly lower rate of CHD events in current hormone users than in never users (RR = 0.38; 95% CI, 0.22-0.66). Overall, with up to 20 years of follow-up, the relative risk of a second event for current hormone users was 0.65 (95% CI, 0.45-0.95); one can only speculate whether the HERS results may also have indicated overall protection had the follow-up been extended for a longer period of time.

Pradaxa Lawsuit News – 2/14/2012: If you were prescribed Pradaxa and have suffered negative side effects, please contact us today so that we can put you in touch with an attorney to advise you of your legal rights.

Pradaxa Lawsuit: There are over 795,000 new and recurrent strokes each year. Someone in the United States has a stroke every 40 seconds. Stroke is the third leading cause of death in America today— and a leading cause of long-term adult disability. Approximately 160,000 people die from stroke every year— and 5.5 million survivors continue to suffer its aftermath. One out of every ten families is touched by stroke.

The American Stroke Association’s definition says it all: “A stroke occurs when blood flow to the brain is interrupted by a blocked or burst blood vessel.” Period. But this sudden disruption can be years in the making. It can be the result of clogged blood vessels in the brain, the buildup over time of the fatty cholesterol deposits that translate into atherosclerosis. This disruption also can be created from a blood clot that travels to the brain from another part of the body, a clot that can become lodged in the blood vessels and, acting like a dam, stop”ping the blood supply from getting through to hungry cells.

Or, less commonly, a stroke can be caused by a weakness in blood vessel walls. This vulnerability, present from birth or from uncontrolled high blood pressure, eventually can cause a blowout in the vessel. The blood then will hemorrhage, or leak out, into the brain. But whatever the disruption, the result is the same: the area beyond the clogged blood vessel, beyond the clot, beyond the hem”orrhaging blowout, is not getting the blood supply that it needs. Like a lawn that isn’t watered in a drought, this area of the brain begins to dry up, to shrivel. The brain cells that aren’t “watered” will die very quickly.

TIA is a name to remember. It stands for transient ischemic at”tack and it can save your life. Sudden blurred vision, numbness or weakness, or difficulty in speaking that lasts only a few min”utes or less than twenty-four hours can be a sign that things are amiss—and that it’s time to take immediate care of yourself. In fact, if you experience these transient symptoms, you should call 911, immediately go to the emergency room, and hopefully pre”vent a stroke.

Whoever coined “There’s more here than meets the eye” could very well have been a neurologist. Frankly, it’s not much to look at. A brain looks like a well-used sponge. But appearances lie. The brain is bursting with energy. It consists of billions of nerve cells called neurons. And these neu”rons are settled in specific locales that are responsible for every”thing from the way we eat to the food we like. And this so-called “sponge” can soak up so much information that nothing, not even the most sophisticated computer in the world, can compare to it. Nothing. As with most things, organization, delegation, and record keeping are crucial factors in its success. Despite its lumpy ap”pearance, the brain is very active and very well organized—and in touch with all its “employees.”

Pradaxa Lawsuit: Veins, arteries, and nerves—all are intertwined, all are intricately spread throughout our bodies. When we touch a hot plate with our fingers, when we step on a nail, when we bang into the corner of a table, when we sip an ice-cold glass of champagne, when”ever our senses are involved, so is our peripheral nervous system, sending our sensations, or stimuli, to our brain for responses. In normal brain functioning, the brain sends messages back down to those nerve endings, telling us to move our fingers from the hot plate or feel the pain of the nail, the table corner, the ice-cold ache of sipping a drink. The peripheral nervous system is like a vast messenger service, the adjunct staff so important to any suc”cessful organization.

The brain feeds on oxygen, which is extracted from red blood cells. It’s assured a constant supply from the high-speed pumping action of the heart, which, despite the soul-searching words of poets and philosophers, is actually a “hard-body” muscle that is about the size of a fist. This “fist,” however, can squirt a jet of life-sustaining blood several feet. You can feel this jet of blood surging through your body by taking your pulse. Each beat of your pulse pushes out about one cup of blood into your bloodstream. But quality is more important than quantity. Believe it or not, our bodies contain only about twelve pints—or twenty-four cups—of blood. This is equivalent to approximately six quarts of milk or the weight of one Thanksgiving turkey.

The twelve pints of blood pumped by the heart are, in effect, used over and over again. They go around and around in an endless circle throughout our bodies, delivering the blood’s oxygen to all our organs and taking away their wastes. This process is called circulation. Briefly, here’s how it works: The heart is divided into four chambers, the. right and left atrium and the right and left ventricle. The oxygen-filled blood from the lungs comes into the left atrium of the heart. It moves into the left ventricle and is pumped out into the bloodstream through the aorta, the “king” of all arteries. From the aorta, blood, carrying our body’s fuel and food, travels through its passageways called arteries. The walls of the arteries are very elastic; they are muscular tubes that branch out, becom”ing smaller and smaller, until they are only one cell thick.

Fuel and oxygen can pass through them. These tiny arteries are called capillaries. The hungry cells in the body, from the muscles to the brain, from the kidneys to the liver, “eat” their fill and deposit carbon dioxide through their cell walls. The depleted, waste-carrying blood now begins its journey home through the veins. The blood is now more sluggish. The heart has used most of its energy to pump oxygen-rich blood into the body; it has less “oomph” for the return trip. Thus, the veins have little “pockets” or valves that catch any “back”flow” to make sure the blood keeps moving toward the heart and doesn’t get backed up. The veins get bigger and bigger until they reach the right atrium of the heart. As the heart pumps and clenches, this blood is pushed into the right ventricle, where it travels to the lungs and fills up once again with oxygen. This oxygen-rich blood journeys back to the left side of the heart, and the cycle begins anew.

Pradaxa Lawsuit: Like the water in your house, circulation needs pressure to keep moving. Your blood pressure is what keeps your blood flowing and moving in a rhythmic way through your arteries. When you get your blood pressure taken, the upper num”ber in the reading, called the systolic pressure, reflects how hard your heart has to squeeze and contract to push the blood through your arteries. A high reading means that your heart is having to squeeze too hard to keep your blood moving. The lower number, or the diastolic pressure, reflects the pressure in your arteries while the heart rests between beats. A high number here means that the pressure remains elevated even when your heart is resting between beats.

Blood flow, its rhythm and pressure, can be affectedby hered”itary factors, kidney disease, weight gain, and cholesterol, a waxy substance that is carried through the bloodstream. As it builds up, cholesterol is deposited on the arterial walls. Eventually, the walls of the arteries thicken to the point where blood may not get through. If these deposits occur in the arteries feeding the heart, this can result in a heart attack. If they accumulate in the arteries feeding the brain, this can result in a stroke.

The brain has a hungry man’s appetite. It needs 20 percent of the total blood supply to get the oxygen and food that it needs. The crucial arteries through which the heart pumps blood up to the hungry brain are called the carotid arteries. Both the right and the left carotid arteries are all-important, branching out into a series of arteries in the front of the neck and into the brain. These arteries grow smaller and smaller as they travel, allowing all the areas of the brain, from the thalamus to the hippocam”pus, from the frontal to the temporal lobes, to get “served” with oxygen-rich blood.

Pradaxa Lawsuit: Blood. We can be upset by the sight of it or donate it to save a life. But whatever the “gut feeling,” blood is literally a carrier—of life. Think of it as a highly reputable moving van, a transporter that carries necessary food to our cells. And there is much more than meets the eye in its red color. If you put a drop of blood under a microscope, you’d see all of the following: Plasma is the liquid that holds the blood cells; it gives the blood its consistency. The red blood cells (or corpuscles) hold the food. They contain the oxygen and the other nutrients (in the chemical form of glucose) that the body needs to survive. After the various organs finish their “meal,” these red blood cells head for the veins, carrying back the “empty plates” to the heart. Red blood cells also give the blood its red color.

The white blood cells are the “superheroes.” They respond to “foreign invaders/’ both by fighting infection and by increasing in number when infection or inflammation threatens the body. The platelets are responsible for clotting. When you cut yourself, platelets “rush in” and begin to create a web, a microscopic gauze of fiber, that traps other blood cells to stop the flow of blood. Problems can arise, however, in the most well-oiled ma”chine—and the human body is no exception. Clotting is crucial if you fall and hurt your knee, if you step on that ever-present nail. However, especially as we get older, our arteries can narrow and develop rough areas, which draw the attention of the platelets.

Tysabri Brain Infection Lawsuit News – 2/22/2012: Please contact us today if you took Tysabri and suffered unusual side effects or other injuries.

Tysabri Brain Infection Lawsuit: The brain directs every voluntary activity in the body (motor functions and the musculoskeletal system), stimulates respiration, oversees digestion, manages growth and development, ensures tissue repair, and serves as Grand Central Station for the nervous system. (The brain contains 6 mil­lion nerve cells, fully half of the body’s entire supply.) The brain is our in­terpreter of the outside world, monitoring information supplied by our five senses. It is also, of course, the center of our thoughts, feelings, and emo­tions. In fact, it is specially constructed for processing that complex mix.

The human brain is divided into two sections—a newer, outer layer called the neocortex or the cerebral cortex, and a more primitive interior re­gion known as the Old Brain or archipallium. The neocortex, called “neo” because it is believed to have evolved more recently, is the seat of percep­tion, learning, cognition, conscience, and morality. The Old Brain, includ­ing the hippocampus and brain stem, is where our moods and emotions dominate—fear, anxiety, happiness, love, excitement, and so on. All mam­mals have the equivalent of our Old Brain, but the large, overdeveloped, multi-wrinkled outside (the neocortex) sets humans apart.

Specialized nerve cells called neurons are the fundamental structure of the brain. The human brain has 100 billion neurons, and each one has as many as 100,000 links to other neurons. It transmits billions of messages between neurons every second. To get over the gap, or synapse, between neurons, those messages rely on chemicals known as neurotransmitters. Neurons store neurotransmitters, releasing them in response to electri­cal signals. The neurotransmitter then attaches to receptors on nearby neu­rons, triggering another electrical signal. This is the way moods, thoughts, emotions, and impulses move throughout the brain. Receptors on neurons are specific to certain neurotransmitters—like a lock and key.

Tysabri Brain Infection Lawsuit: You never get any more neurons than you are born with. In fact, the brain loses nerve cells as it ages (and in the event of brain injury). Aging also cuts down on the number of extensions from the neu­rons (dendrites) that connect to other neurons, so communication between brain cells gets more difficult the older you get. Levels of some of the neurotransmitters charged with carrying positive feel­ings decrease. In addition, by age forty-five, levels of a powerful enzyme that is responsible for breaking down several types of neurotransmitters increase. The stepped-up breakdown can throw your brain chemistry out of balance and lead to, among many other things, a decrease in the general level of brain activity, inter­ference with the ability to think and remember, and depression.

Certainly, none of this has to mean senility or the loss of mental function that we (wrongly) associate with getting older. You have plenty of neurons to keep you mentally strong for your entire life if you care for them well; and providing the materials for all the neu­rotransmitters you need is within your control. But aging can mean that your brain chemistry tips out of balance more easily if you don’t provide proper nutrition. Looking at it another way, people may get away with sloppy eating habits in their youth, but those habits eventually catch up with them.

The disproportionate opportunities for failure, rather than success, make it that much more crucial that our brains get a constant supply of the correct neurotransmitters, and the raw materials for making them, in order to keep working smoothly. By and large, neurotransmitters become inactive once they’re delivered a message, and they need to be replenished. Though they exist throughout the body, they cannot move into the brain from out­side it, in order to protect it from fluctuations of neurotransmitters in the blood. Instead, they are made “on site”—in the brain, where and when they are needed. (It is also possible to have too much of a particular neurotrans­mitter, and breakdown is an important step in controlling this. Your body will make only what it needs from available materials.)

Tysabri Brain Infection Lawsuit: Neurotransmitters are made from amino acids (the building blocks of all proteins), which we get from the food we eat. Poor diet, then, can leave us without the ability to make the chemical messengers necessary for healthy brain function. Optimal nutrition, through high-quality food and, as necessary, supplements, maintains balance in the brain, which allows for a plentiful supply of the appropriate neurotransmitters and a general mood of well-being and comfort. Your brain physically changes in response to your experiences. Neu­rons develop new connections thanks to new sensations and even thoughts. While you learn something, or try something new, or go through something for the first time, your brain actually grows or alters its structure to accommodate that information.

An electron microscope is an imposing instrument, about six feet high, housed inside a small darkened room designed exclusively for this instrument and the support equipment it requires—high voltage trans­formers, vacuum pumps, and a liquid nitrogen tank. A heavy steel col­umn about ten inches in diameter rises up to the ceiling from a workstation console, encrusted with buttons, switches, knobs, flashing indicator lights, digital numerical displays, and video monitors. Sprout­ing out of the top of the column is a heavy, two-inch-diameter electrical cable, which delivers 100,000 volts to the electron gun at the top of the column. Liquid nitrogen billows out a white cold fog spilling down from the top of the column in the darkened room like liquid oxygen from a rocket on the launchpad at dawn.

After placing the sample in the microscope and energizing the electron gun, Morest sees shadowy patterns come into focus on a phos­phorescent screen. Anyone not trained in interpreting these shadowy patterns would see nothing more than grey doodles on a glowing yel- low-green background. But the electron microscopist, with his head pressed against the column to look at the glowing screen through a thick glass window, is transported inside a cell of this rat’s brain. The tiny slice is now expanded into an immense new universe. Turning wheels simul­taneously with both hands he moves the grid, scanning acres of cellular territory for hours, completely absorbed in the new world he is seeing. Hours later he emerges from the room with a telltale flat spot embossed into the center of his forehead from pressing it against the column.

Increasing the magni­fication in an electron microscope is like seeing the ground spinning below as you descend swinging from a parachute, bringing greater and greater detail as you approach the ground. Mo rest must keep his bear­ings through all of these dizzying twists, maintaining a conceptual thread back through the slicing process to the way the tissue was ori­ented in the brain of the rat He will have to analyze hundreds of sections to reconstruct the three-dimensional cellular structure correctly, a pro­cess requiring months or years of work.

Tysabri Brain Infection Lawsuit:

Some research­ers suggest that augmenting these beneficial actions of microglia would be the best therapy Microglia do indeed target and kill neurons that are infected with the disease-causing prions and thus they do damage neu­ral circuitry, but in doing so they may protect the brain by limiting the spread of the diseased prion. Microglia also engulf the deposits of PrP outside neurons, thus eliminating or slowing the accumulation of PrP plaques. Once infected by prion, however, the ability of microglia to consume particles of PrP becomes impaired. Dysfunctional microglia might even contribute to the disease, making some people more suscep­tible to prion infection than others.

This is essential for synaptic transmission and to prevent glu­tamate from rising to toxic levels. In CJD, microglia transform to take over this vital function as astrocytes become infected and die. The trans­porter molecule in the cell membrane that absorbs the n euro transmitter glutamate into astrocytes starts to be synthesized in microglia during prion infection. Now equipped with the glutamate transporter of astro­cytes, microglia step in for their fallen glial comrades to lower the toxic levels of this neurotransmitter in damaged brain tissue. This protects neurons from death due to overstimulation by the excess glutamate.

Finally, microglia could be helpful in diagnosing prion disease. Microglia develop distinct cellular changes in response to prion infec­tion, and these alterations can be detected with appropriate diagnostic techniques. Much as monitoring changes in blood cell count informs doctors of the type and severity of infections in the body, one can imag­ine that careful monitoring of changes in microglia could provide criti­cal insight into infection in the brain. Interestingly, current evidence suggests that oligodendrocytes are not capable of supporting replication of the infectious prion protein. Tin’s resistance sets them apart from both neurons and astrocytes. However, oligodendrocytes and myelin suffer damage in prion disease. Other studies indicate that oligodendrocytes are killed by oxidative injury ac­companying prion infection.

Tysabri Class Action Lawsuit: Recall that PrP is a normal protein in neurons that becomes mutated and infectious in prion disease. The biological role of the normal PrP in cells is still mysterious. In 2005 it was reported that normal PrP is found in purified myelin and in oligodendrocytes. In 2007, Frank Baumann and colleagues from the University Hospital of Zurich, Switzerland, re­ported that a mutation in a particular part of PrP caused myelin break­down in both the central and peripheral nervous systems of mice. This study suggests that myelin integrity must be maintained by some un­known action of the normal PrP in myelin. By studying the role of PrP in myelin, we may learn more about the normal function of this protein in cells.

How do the 100 billion neurons in our brain allow us to remember who we are; to learn, think, and dream; to be stirred by passion or rage; to ride a bike or conjure meaning from inked patterns on paper; or to pluck out instantly a mothers voice from the muddle of a noisy crowd? What goes wrong with neural circuits in schizophrenia or depression, or in dreadful diseases like Alzheimer’s, multiple sclerosis, chronic pain, or paralysis?

We are on the cusp of a new understanding of the brain that trans­forms a century of conventional thinking about the brain, specifically the role of the brains neurons. Crowding around the computer screen in a darkened room in 1990, scientists watched information passing through peculiar brain cells, bypassing neurons and communicating without using electrical impulses. Until this discovery scientists had presumed that information in the brain flowed only through neurons by using electricity. In fact, a mere 15 percent of the cells in our brain are neurons. The rest of our brain cells—called glia—have been over­looked as little more than packing material stuffed between the electric neurons. “Housekeeping cells” they were called. Dismissed as cellular domestic servants, glia were neglected for more than a century after they were discovered.

A neuron from the brain of a genius was indistinguishable from one taken from a typical brain. And on average, there were just as many neurons in Einstein’s creative cerebral cortex as in the cortex of men not noted for being unusually creative. But there was one difference in the data. The number of cells that were not neurons was off the charts in all four areas of Einsteins brain. On average, the samples from normal brain tissue had one cell that was not a neuron for every two neurons counted, but the samples from Einsteins brain had nearly twice as many nonneuronal cells, about one for every neuron. The biggest difference was seen in the sample of parietal cortex from the dominant side of Einsteins brain, the region where abstract concepts, visual imagery, and complex thinking take place. Was this a fluke? Diamond calculated the mathematical odds that this difference could have happened by chance, considering the range of variation in the control tissue samples. In all the regions sampled from Einsteins brain the odds that the difference could have occurred by chance were small.

Tysabri Class Action Lawsuit: The rest of the brain is white matter. This glistening-white brain tissue is a mass of millions of tightly bundled communication lines connecting neurons between distant points in the brain. These vital communication lines are packed beneath the grey matter cortex, much like tightly wound fibers beneath the leather skin of a baseball. White matter in the brain, like white space on paper, is easily dismissed as something defining the areas between the functional components, but recently this naive view has been changing. Unraveling this part of the brain is such a daunting task that only in the last few years have new brain imaging techniques allowed scientists to venture into the white matter realm. As we will see later, these new findings are changing fundamental concepts about how the brain processes and stores information—how we learn. Here inside the blank white regions of brain, glia are the heart of the mechanism.

A revolution in our understanding of how the brain is built, how it functions, how it fails in mental illness and disease, and how it is repaired has been ignited with the recent exploration of these long- neglected brain cells. Glia are the key to understanding this new view of the brain. There is little or no information available about these cells to nonscientists, so we can begin our inquiry with about as much knowl­edge as the pioneering scientists who discovered these various odd brain cells. Since the answers are known to only a few specialists, we can ex­perience the same puzzles, clues, and revelations as the scientists who sleuthed out these peculiar cells in the brain. When these clues are as­sembled, will they reveal another brain working in parallel with our neuronal brain?

Before venturing further, it is essential that we proceed from a common base of knowledge about how the brain operates at the level of cells and circuits. The nervous system works by sending electrical impulses down a wire-like axon at top speeds of 200 miles per hour. Impulses travel through some axons, such as pain fibers, much more slowly—only 2 miles per hour, the pace of our footsteps in a slow walk. This explains the build-up to the full painful sensation when you accidentally hit your thumb with a hammer. The reason for the hundred-fold increase in transmission speed through our high-speed nerve fibers is that they are wrapped with electrical insulation, called myelin. In contrast, pain fibers are uninsulated thread-like axons.

Neurons are not fused to one another like copper wires soldered in a circuit; instead, each neuron in your brain is an island unto itself. Each of these neuronal islands communi­cates by sending a message to another neuron across a tiny gulf of the saltwater that bathes every cell in your body. Because of this gulf of separation, information is not passed on to the next neuron in a circuit by electricity. Instead, the neuron floats chemical messages across the gulf to reach the neuron on the other side. This gulf is the synapse, and the neurons on either side are called presynaptic or postsynaptic neu­rons, depending on whether they are the sending or receiving shore of the gulf. The presynaptic neuron is always the one sending the message from its axon tip; the postsynaptic neuron receives messages across the synapse through its root-like dendrites.

Tysabri Class Action Lawsuit News: News and Information

Tysabri Class Action Lawsuit: The messages are sent in the form of a chemical substance called a neurotransmitter. Microscopic “bottles” inside neurons, called synaptic vesicles, are filled with neurotransmitter molecules. Each synaptic vesi­cle is a tiny sphere too small to see with a light microscope; they are visible only under the high-power magnification of an electron micro­scope. The messages are not floated across the synaptic gulf in these spherical bottles, as you might expect; instead, their contents are dumped into the gulf and diffuse across to the opposite shore. Synaptic vesicles accumulate inside the axon right next to the cell membrane at the tip.

Like cellular water balloons, one or more synaptic vesicles are smashed against the cell membrane of the axon by the force of the electrical im­pulse when it arrives, releasing the vesicles contents into the cellular sea. The neurotransmitter then flows across the synaptic gulf to reach the postsynaptic neuron on the other side.

Sentinel molecules along the shore of the postsynaptic neuron are specially designed to detect the neurotransmitter substance in the syn­aptic gulf. These neurotransmitter receptors are large protein molecules acting as biological nanomachines. In each neurotransmitter receptor there is a passageway that can open into the dendrite of the receiving neuron when neurotransmitter is detected. When the tunnel through the receptor opens briefly, charged ions floating in solution leak out, reducing the voltage inside the postsynaptic neuron. This brief drop in voltage in the postsynaptic neuron is the receiving signal, called the postsynaptic potential. If the synaptic voltage change is big enough, the voltage drop triggers the postsynaptic neuron to fire an impulse out its own axon to signal the next neuron in the circuit. This may seem an awkward way to design a nervous system, but consider the engineering challenge facing Nature: to build a powerful, high-speed biological com­puter using nothing other than cells—tiny bags of saltwater.

So the nerve impulse speeds down an axon, releasing neurotrans­mitter when it reaches the end. The neuro transmitter flows across the synaptic gulf and activates neurotransmitter receptors on the postsyn­aptic neuron, causing a voltage drop in the recipient neuron that will make it fire an electric impulse down its own axon to release neurotrans­mitter onto dendrites of the next neuron in the circuit in relay fashion. To reduce the time it takes for neuro transmitter to diffuse across the syn apse, the gulf of separation is infinitesimally narrow (25 billionths of a meter). The synaptic cleft is so narrow, in fact, it is impossible to see the separation through the most powerful light microscopes. This fact caused decades of controversy in the field of neuroscience until the elec­tron microscope proved that every synapse in the body has a gulf of separation between the pre- and postsynaptic neurons. A message passes across the synapse in about one-tenth of an eye blink, but compared with the two hundred mile per hour speed of the neural impulse, the synapse slows information flow much like a toll booth on a turnpike.

Tysabri Class Action Lawsuit: When your doctor taps his rubber mallet below your knee to test your knee-jerk reflex, you are seeing a circuit in action that controls the vital coordination crucial for you to walk. Should you stub your toe as you are walking, this misstep will jerk the tendon below your kneecap, just as your doctor does with his mallet. To avoid stumbling, you must now quickly swing your lower leg forward to catch your fall mid-stride. It is vital that this entire sensory-motor reflex is executed in a split sec­ond of time, otherwise you will trip and fall.

To execute this lightning-speed response, there is only one synapse in the entire circuitry controlling the vital reflex that keeps you on your toes. When nerve endings in your kneecap tendon sense a sudden tug from a stubbed toe (or doctor’s mallet), they shoot impulses at two hun­dred miles per hour up the axon from the nerve endings into your spine. There is no time to send signals to your brain; instead, there in your spinal cord a single synapse separates this sensory neuron (bringing information about your leg motion into your spine) from a motor neu­ron that will fire electrical impulses down to your leg muscle to jerk your lower leg forward in a flash—one synapse separating us from falling on our face. (The messages will be relayed by other nerve circuits to your brain, but they arrive after your leg muscles have already responded, and you have no conscious control over what has happened. This is why the doctors mallet triggering the knee-jerk reflex always delights us with surprise as we watch our leg react automatically.)

Synapses do much more than connect neurons; they enable flexibility of information processing. Synapses permit adjustments in functional connections based on experience. The process of learning is more finely regulated than simply making and breaking synapses: the strength of a synaptic connection can be finely tuned in a process called synaptic plas­ticity. How? The molecular changes that strengthen or weaken a synaptic connection are intensely studied by neuroscientists interested in memory and learning, but in principle, the mechanisms are quite simple. Either by releasing a bit more neurotransmitter from the pre-synaptic ending when an impulse arrives, or by adjusting the sensitivity of the postsynaptic neuron receiving the neurotransmitter signal, the same input to a syn­apse can produce greater or lesser voltage change in the postsynaptic neuron, thereby weakening or strengthening the connection.

But there is one additional crucial aspect to this process of synaptic transmission: cleanup. Communication across a synapse would fail if the synaptic gulf were not cleared of n euro transmitter quickly to permit another message to be sent. It was long understood that glia bordering the synaptic cleft carried out this cleanup operation. Protein molecules in the glial membrane pump the neurotransmitter out of the synaptic cleft and into the astrocyte—one of the four major kinds of glial cells— where it is reprocessed. After filtering out the neurotransmitter and re­cycling it into an inert form that cannot be confused as a signal, the astrocyte surrounding a synapse delivers the reprocessed substance back to the presynaptic nerve terminal. The neuron then carries out a simple chemical reaction to convert the inert neurotransmitter back into active neurotransmitter and repackages it into synaptic vesicles.

If neurotransmitter is not taken up efficiently, communication across a synapse will fail because the gulf will become saturated with stale mes­sages. If neurotransmitter is taken up too quickly, the message will ap­pear too briefly to have full effect on the postsynaptic cell. If the energy requirements of the neuron cannot be met by the nutrients supplied by astrocytes, the neuron will run out of gas. Astrocytes are thus in a posi­tion of control.

Tysabri Lawyers: Like sponges, astrocytes absorb discarded potassium ions from the space around neurons, sucking them into their own cytoplasm. Potas­sium ions are released by neurons when they fire an electrical impulse. Accumulating these excess positive charges inside astrocytes does not create a problem for glial function, because glia do not communicate by firing electrical impulses. Removing the excess potassium is essential for recharging neurons.

How do astrocytes collect and dispose of the excess potassium ions? Astrocytes are connected to one another in avast multicellular network through protein channels called gap junctions. Gap junctions not only couple astrocytes together like snaps on a jacket, they allow potassium to flow freely through the channels and between adjacent glial cells. These gap-junction connections between astrocytes allow them to si­phon off potassium from around a neuron that is actively dumping po­tassium ions as it fires impulses, dispersing the excess positive ions into the network of astrocytes, The community of glial cells, coupled by gap junctions, works cooperatively to maintain the proper potassium ion concentration outside neurons. To dispose of the excess potassium, spe­cialized astrocytes have structures called end feet. These cellular exten­sions grasp small blood vessels like the clinging feet of a bat. Through these end feet, astrocytes dump the accumulated potassium into the bloodstream, as if it were ridding the brain of the waste generated by neuronal activity.

The consequences of glia failing to maintain potassium ions at the proper concentration outside neurons are obvious. During high states of neuronal activity—the extreme being a brain seizure—the potassium concentration builds up around neurons quickly, and its removal by astrocytes is crucial. Without astrocytes sopping up potassium ions, the brain will run out of electrical power. When it is unable to fully recharge its neuronal batteries, the brain waves go flat. In comparison to normal brain waves, these flattened brain waves, called spreading depression, are much like the dim flash of a camera strobe, too feeble to work prop­erly. These depressed waves are seen in EEG recordings accompanying many pathological conditions.

Tysabri Lawyers : Recent research has found that astrocytes markedly change their calcium signaling in animals in which seizures have been induced ex­perimentally. Normally the amount of calcium signaling between astro­cytes in brain cortex is relatively moderate, but after a seizure these astrocytes typically show large oscillations in calcium signals. They sweep through the cortex in strong waves, presumably releasing more glutamate and tipping the brain toward seizure. The evidence suggests that these changes in astrocyte calcium signaling are permanent changes following repeated seizures, rather than echoes in the wake of increased calcium signaling in astrocytes induced during the seizure itself. Possi­bly this change in astrocyte calcium signaling after seizure could be beneficial, but early research suggests that damping the excessive astro­cyte signaling with drugs improves the outcome and limits the death of neurons in animal models of epilepsy.

As mentioned previously, interesting new research reveals that patients with bipolar disorder and schizophrenia also have fewer oligo­dendrocytes, the myelinating cell of the brain. These glial cells wrap axons with myelin, but they are not thought to be involved in glutamate regulation. Nevertheless, too much glutamate can be just as toxic to myelinating glia as it is for neurons. This could be another way glia par­ticipate in mental illness, because when the myelin insulation becomes frayed, so does mental function.

Excess glutamate in the brain may be one of the main causes of death of myelinating glia in the brains of people suffering overproduction of this neurotransmitter. The effects of glutamate on myelinating glia might influence cognitive function even though these cells are not associated with synapses. When one considers that prefrontal lobotomy works by severing the connections to the forebrain, and seeing how the process completely changes a persons personality, it is not difficult to imagine how a pathological loss of myelinating glial cells in these forebrain tracts could lead to psychiatric disorders such as schizophrenia and other mental impairments. Breaking the insulation 011 critical communication cables in the brain will disrupt communication as effectively as severing the cable.

Electroconvulsive shock has a therapeutic effect on clinical depres­sion and schizophrenia by resetting brain waves, but electroconvulsive shock therapy may also activate a beneficial injury response in the brain. Since astrocytes and microglia are the first line of defense in any brain injury, it is obvious why altered glia would be seen in regions of the brain giving rise to seizures. This injury response of glia to brain seizure may also be one of the cellular mechanisms that explains the changed brain function induced by electroshock therapy. Both microg­lia and astrocytes release growth factors in response to brain stress and injury. These growth factors sustain neurons under neurotoxic condi­tions that would normally kill them, and in the healthy brain these glial- derived growth factors promote neuronal growth and health. Both microglia and astrocytes release many different natural inflammatory agents to aid in the healing process, and all of these glial responses prob­ably contribute to the therapeutic effect of electroshock treatment.

Tysabri Lawyers: This neurovascular unit, as the astrocyte-capillary-neuron group is now called, is also intimately involved in another form of pain and disability suffered by millions of people. Migraines are debilitating vascular head­aches originating within the brain. Electrical impulses spreading to other regions of the brain change nerve cell activity and together with the resulting disturbances in local blood flow cause symptoms that can include visual disturbance, numbness, tingling, and dizziness. This spreading depression of brain waves was described previously in asso­ciation with epilepsy. The same phenomenon occurs in migraine, and here too, astrocytes have a role in the process.

These vascular headaches are caused by blood vessels in the brain dilating excessively and triggering pain and inflammation in the sur­rounding regions. The inflammation triggers the trigeminal nerve, re­sulting in a severe throbbing headache originating in the meninges, the skin-like cells that cover the brain. The senses become hypersensi­tive, so that normal sound and light cause excruciating pain. Nausea, vomiting, loss of appetite, and mood disturbances can accompany mi­graine attacks, and patients often experience auras, visual halos and hallucinations caused by abnormal nerve cell activity in blood-starved cortical regions where vision is processed.

Migraines occur on a periodic basis and they disproportionately affect women. Hormonal effects are thus suspected to have a role in migraine, but it is also in part an inherited disorder. Once we know more about the molecular mechanisms astrocytes use to sense neural activity and control brain waves and local blood flow, new treatments may be devised to control the problem at its source rather than simply trying to blunt the painful aftereffects when the intricate cooperation between neuron, glia, and blood vessel goes awry.

Still, it is surprising that the long-held and well-accepted role of glia as first responders to neuronal injury did not stimulate more vigorous research into exploiting glia for new investigative methods and treat­ments for brain disease and injury. Neuroscientists and the scientific establishment (research funding agencies, editors at scientific journals, and even biomedical companies) were slow to move in this promising direction. Few who marvel at the wondrous new imaging of functional activity in the human brain appreciate that they are seeing the power of glia at work in the brain, both in health and in sickness, as they promote information processing and sustain neuronal function.

Tysabri Lawyers: People with Ashlyns congenital condition, called CIPA (congenital insensitivity to pain with anhidrosis), usually die before the age of twenty-five. Injury or infection will take them. They have no gag reflex, never feel the tickle to sneeze or the scratchy throat to cough. Never—no matter how severe her injury or what the cause—can Ashlyn tell the doctor where it hurts. Such children are insensible to an inflamed ap­pendix or an ear infection, so the infections rage undetected. As babies they never cry out in pain or develop the alarm and panic reflex at the sight of their own blood. To these babies blood is merely a curiosity. Sadly, grotesquely, but understandably, her own blood was a gruesome plaything for baby Ashlyn. These people, normal in every other respect, suffer painlessly and die prematurely because of a genetic defect that weakens and kills their pain neurons before birth.

In contrast to this puzzle of injury without pain, many people suffer the converse: pain without injury. Chronic pain is not the warning slap of acute pain that saves us from further injury. That pain subsides on its own. Strangely, chronic pain often develops after an injury has healed. It intensifies when there are no longer any noxious or injurious signals to excite pain neurons, yet these neurons scream out in gut-wrenching pain nevertheless. The ceaseless intense pain controls the lives of such chronic sufferers. Pain robs them of sleep and blots out all pleasure from their lives by imposing constant misery. A normally pleasant touch or sensation ignites raging flames of pain. Putting on a pair of socks may be unbearable.

Some patients are forced to accumulate and consume such large quantities of painkillers that the police become suspicious. Doctors who treat patients suffering chronic pain can attract scrutiny from the au­thorities for the high volume of narcotic drugs they must dispense to relieve these patients’ agonies—doses of narcotic drugs that could be fatal for a person without tolerance. At the risk of drawing unwanted attention from police and health insurance companies, many doctors are compelled to limit the dosage of pain medications to levels they know are no longer effective for the patient grown tolerant to them.

With an increasing appreciation of glia in nervous system function, some pain researchers have begun examining the most improbable of suspects, and they have found the culprit. These scientific sleuths were awakened to the improbable realization that the source of chronic pain is not in pain neurons themselves, but rather in glia. This insight is not only leading to new treatments for chronic pain; it is cracking the case of drug addiction to heroin and other narcotics.
