Anapol Schwartz Attorneys at Law LINKS TO CONTENTS: CABG - CORONARY ARTERY BYPASS WHAT IS CABG? (PRONOUNCED: CABBAGE) CABG is a surgical procedure used to treat patients with coronary artery block- ages. During the procedure, a heart surgeon creates an alternate path for blood to flow to the heart muscle by going around, or bypassing, a blocked section of an artery. Hence, the phrase, heart bypass surgery. CABG is typically recommended for severe blockages that are not treatable by other The surgeon typically gains access to the heart by cutting the sternum (breast bone). Often blood vessels are removed from the patient's leg or detached from the chest wall and grafted to the blocked artery. Once the grafts have been attached, oxygen rich blood will flow through the new bypass vessel, avoiding the blockage completely.
CABG is performed by a cardiothoracic surgeon under general anesthesia and generally takes between two and six hours depending on the number of bypasses to be completed. Patients might have more than one blockage, so several bypasses may be needed. After the procedure is completed, most patients stay in the hospital for several days and face a rehabilitation period of one to two months.

Anapol Schwartz Attorneys at Law WHO IS ELIGIBLE FOR CABG SURGERY? Not everyone is a candidate for CABG — the decision to prescribe cardiac bypass surgery depends on several factors including the extent of cardiovascular disease, the severity of symptoms, your age, and other medical conditions. The heart specialist and surgeon will determine the best method of treatment and your WHAT HAPPENS DURING CABG SURGERY? The surgery generally lasts from two to six hours, depending on the number of arteries being bypassed. After general anesthesia is administered, the surgeon removes the veins or prepares the arteries for grafting. GRAFT PREPARATION
There are several types of bypass grafts that can be used. The decision to use which grafts depends on the location of the blockage,
the amount of the blockage, and the size of the patient's coronary arteries.
Internal mammary arteries or internal thoracic arteries are the most common bypass grafts because they show the best long-term
results. In most cases, these arteries can be kept intact at their origin because they have their own oxygen-rich blood supply, and are then sewn to the coronary artery below the site of the blockage. If the surgeon removes the mammary artery from its origin, it is called a free mammary artery. Over the last decade, more than 90 percent of all patients received at least one internal artery graft.
The radial (arm) artery is another common type of arterial graft. There are two arteries in the arm, the ulnar and radial arteries. Most
people receive blood to their arm from the ulnar artery and will not have any side effects if the radial artery is used. Careful preoperative and intra-operative tests determine if the radial artery can be used. If the radial artery is used as the graft, the patient may be required to take a calcium channel blocker medication for several months after surgery. This medication helps keep the artery open. Some people report numbness in the wrist after surgery. However, long-term sensory loss or numbness is uncommon.
The gastroepiploic artery to the stomach and the inferior epigastric artery to the abdominal wall are less commonly used for grafting.
Saphenous (leg) veins can be used as bypass grafts. Minimally invasive saphenous vein removal does not require a long incision. One
to two incisions are made at the knee and a small incision is made at the groin. This results in less scarring and a faster recovery. Guide to Causes of Renal Failure and Strokes Following Coronary Surgery by Anapol Schwartz Law Firm. 2007 All Rights Reserved.

Anapol Schwartz Attorneys at Law SURGICAL PROCEDURE To bypass the blockage, the surgeon makes a small opening just below the blockage in the diseased coronary artery. If a saphenous (leg) or radial (arm) vein is used, one end is connected to the coronary artery and the other to the aorta. If a mammary artery is used, one end is connected to the coronary artery while the other remains attached to the aorta. The graft is sewn into the opening, redirecting the blood flow around this blockage.
The procedure is repeated until all affected coronary arteries are treated. It is common for three or four coronary arteries to be bypassed during surgery. HEART-LUNG MACHINE / ON-PUMP SURGERY The heart-lung machine maintains life despite the lack of a heartbeat, removing carbon dioxide from the blood and replacing it with oxygen before pumping it around the body. During surgery, the heart-lung bypass machine (called on-pump surgery) is used to take over for the heart and lungs, allowing the circulation of blood throughout the rest of the body. The heart's beating is stopped so the surgeon can perform the bypass procedure on a still heart. The heart-lung machine has saved countless lives.
OFF-PUMP OR BEATING HEART BYPASS SURGERY Off-pump or beating CABG surgery allows surgeons to perform surgery on the heart while it is still beating; thusly, the heart-
lung machine is not used. The surgeon uses advanced operating equipment to stabilize portions of the heart and bypass the blocked
artery in a highly controlled operative environment. Meanwhile, the rest of the heart keeps pumping and circulating blood to the body.
Off-pump coronary artery bypass graft surgery may be performed in certain patients with coronary artery disease. With present
technology, all arteries on the heart can be bypassed off-pump. It may be ideal for certain patients who are at increased risk for compli-
cations from cardiopulmonary bypass, such as those who have heavy aortic calcification, carotid artery stenosis, prior stroke, or
compromised pulmonary or renal function. Not all patients are a candidate. Who undergoes off-pump surgery is made at the time of
surgery when the patient's heart and arteries are evaluated more closely.
The goal of off-pump bypass surgery is to decrease the morbidity of CABG surgery, such as stroke, renal failure, and the need
for blood transfusion.
Also of great interest is the possibility that the off-pump approach may lessen the risk of what are called cogni-
tive changes that have been seen in many patients who underwent CABG with cardiopulmonary bypass. These short-term changes
include memory loss, difficulty thinking clearly, and problems concentrating for lengthy periods. They usually improve over the months
following surgery.

Anapol Schwartz Attorneys at Law HOW SUCCESSFUL IS CABG SURGERY? Studies have shown in 80 to 95 percent of patients, bypasses made with segments of the mammary artery still performed efficiently 10 years after surgery. Two-thirds to 75 percent of patients who received grafts from leg veins still had satisfactorily unrestricted blood flow after 10 years. Even if your graft becomes blocked, you may not need additional bypass surgery. However, you may be a candidate for balloon angioplasty and insertion of a stent.
DRUG ELUTING STENTS (DES) A stent is a small, lattice-shaped, metal tube that is inserted permanently into an artery. The stent helps hold open an artery so that blood can flow through it. Drug- eluting stents are stents that contain drugs that potentially reduce the chance that arteries will become blocked again.

Anapol Schwartz Attorneys at Law BRIEF HISTORY OF STENTINGThe concept of the stent grew directly out of interventional cardiologists' experience with angioplasty balloons in the first decade of use (1977-87). Sometimes the wall of the coronary artery became weakened after balloon dilatation. Although the artery would be opened successfully using a balloon, in a small percentage of cases, the artery would collapse after the balloon was deflated when the patient had been moved to the recovery room. Since there was no interventional fix available, the only option was emergency bypass graft surgery to repair the problem.
Another problem soon became evident as well. Approximately 30 percent of all coronary arteries began to close up again after balloon angioplasty. By the mid 1980s various radiologists and cardiologists were working on solutions to these problems, designing new devices in hopes they would provide more safety and durability to the procedures. Lasers, tiny shavers, rotational polishers — many tools were miniaturized to be delivered via catheter.
One such device was the stent — a metal tube or scaffold that was inserted after balloon angioplasty. The stent itself was mounted on a balloon and could be opened once inside the coronary artery. In 1986, working in Toulouse, France, Jacques Puel and Ulrich Sigwart inserted the first stent into a human coronary artery. In 1994, the first Palmaz-Schatz stent was approved for use in the United States. Over the next decade, several generations of bare metal stents were developed, with each succeeding one being more flexible and easier to deliver to the narrowing.
STENT WARS Heart disease is here to stay. Let the stent wars begin. The status and availability of drug- eluting stents is the subject of many legal disputes. Stents have been adopted so quickly that they have doubled the world market for stents usage to $5 billion annually. It is easy to under- stand the flurry of activity among and between all of the competing device manufacturers.
Currently only two drug-eluting stents, the Cordis CYPHER™ sirolimus-eluting stent and the Boston Scientific TAXUS™ paclitaxel-eluting stent system, have received FDA approval for sale in the United States (the Cypher stent in April 2003; the Taxus stent was approved a year later in March 2004) as well as the CE mark for sale in Europe. In addition, Medtronic's Endeavor stent which uses ABT-578, a drug made by Abbott, was approved in Europe in April 2005. Abbott had its own Zomaxx stent in clinical trials, but cancelled its development in the fall of 2006, opting instead to market the Xience stent, which it co-acquired as part of the Boston Scientific/Guidant/Abbott merger agreement. Boston Scientific has launched its second generation Taxus Liberte stent in Europe and is also going to be marketing the Xience, under the brand name Promus.

Anapol Schwartz Attorneys at Law Meanwhile, a number of new second and third generation stent technologies are in research, clinical trial phases, or have achieved marketing approval outside the United States. A new stent design by Conor MedSystems was approved in Europe in February 2006. Conor's CoStar stent utilizes a bioresorbable polymer to deliver the anti- restenosis drug, so that after a few months of drug elution, the stent in effect becomes a bare metal stent — which may eliminate the concern of late stent throm- bosis present in permanent polymer stents. And both Abbott and Germany-based Biotronik are testing a completely bioabsorable stent which will totally disappear after it has done its work. FDA WARNING: STENT THROMBOSIS The issue of stent thrombosis also is being examined in more depth. In October 2003, the FDA issued a warning regarding cases of sub-acute thrombosis (blood clotting) with the CYPHER stent that resulted in some deaths. Upon further study, it seemed that the incidence of thrombosis was no greater than that with bare metal Late stent thrombosis was one of the major issues discussed at the FDA scheduled a public meeting in early December 2006 on the issue. For the first time since their CARDIAC SURGERY - introduction, the use of drug-eluting stents began to decrease slightly in late 2006, RISKS AND BENEFITS due to these concerns.

Guide to Causes of Renal Failure and Strokes Following Coronary Surgery by Anapol Schwartz Law Firm. 2007 All Rights Reserved. Anapol Schwartz Attorneys at Law DRUG ELUTING STENTS: WHAT CAN GO WRONG? Stent placement can cause infection, blood clots, and bleeding at the site of the stent. Other rare complications of coronary stents include chest pain, heart attack, or tearing of blood vessel. The stent can move out of place (stent migration). In some cases, plaque can reappear in the stented artery (stent restenosis). Ask your doctor about the additional risks and restrictions associated with stents and drug eluting stents.
The types of adverse events seen with the drug-eluting stent were similar to those that occurred with the uncoated stent. Patients who are allergic to sirolimus or to stainless steel should not receive a Cypher stent. Caution is also recommended for people who have had recent cardiac surgery and for women who may be pregnant or who are nursing. Patients who receive the drug-eluting stent will likely need to take certain kinds of anti-platelet drugs for at least several months. A failure to do so can result in the formation of clots.
The risk in some cases is a failure of the doctor to keep a patient on anti-platelet drugs (Plavix, Ticlid, Aspirin) for the correct time period. If a patient is taken off of those drugs too soon, there is an increased potential for clots causing heart attack or stroke. In those situations, where a stroke or heart attack occurred after a doctor has taken the patient off of the anti-platelet medication, one should consider consulting a lawyer about whether or not this medical decision constituted a deviation of the proper standards of medical care.
CABG SURGERY: WHAT CAN GO WRONG?During heart bypass surgery, Aprotinin/Trasylol is an injection used to prevent excessive blood loss. Aprotinin has been linked to encephalopathy and degenerative brain diseases. Aprotinin/Trasylol doubles the risk of kidney failure and stroke and increases the risk of heart failure or heart attack by 55 percent. There are risks of renal failure with CABG even without Trasylol, related to how long a patient is on the heart lung machine.
There are other generic alternatives to be used in CABG surgeries. Among them are Amicar (aminocaproic acid) and Cyklokapron (tranexamic acid. Also studied, these generic drugs were confirmed to be both safe and effective. Some researchers estimated that if hospitals stopped using Trasylol and instead used the above generic drugs, it would save 9,000 to 11,000 people every year from kidney dialysis. The differences in bypass surgery drug costs are also alarming:
• Trasylol (aprotinin) costs $1,300 per dose (manufactured by Bayer AG) • Amicar costs only $11 per dose (generic, off-label use) • Cyklokapron costs $44 per dose (generic, off-label use) Guide to Causes of Renal Failure and Strokes Following Coronary Surgery by Anapol Schwartz Law Firm. 2007 All Rights Reserved.

Guide to Causes of Renal Failure and Strokes Following Coronary Surgery by Anapol Schwartz Law Firm. 2007 All Rights Reserved. Anapol Schwartz Attorneys at Law WHAT IS DIALYSIS?
There are two kinds of dialysis: hemodialysis and peritoneal.
Hemodialysis cleans and filters your blood using a machine to temporarily rid your body of harmful wastes, extra salt, and extra water. Hemodialysis helps control blood pressure and helps your body keep the proper balance of important chemicals such as potassium, sodium, calcium, and bicarbonate.
Hemodialysis uses a special filter called a dialyzer that functions as an artificial kidney to clean your blood. During treatment, your blood travels through tubes into the dialyzer, which filters out wastes and extra water. Then the cleaned blood flows through another set of tubes back into your body. The dialyzer is connected to a machine that monitors blood flow and removes wastes from the blood. Hemodialysis is usually needed three times a week. Each treatment lasts from three to five or more hours. During treatment, you can read, write, sleep, talk, or watch TV. Patients on hemodialysis must follow a strict, limited diet. Hemodialysis can be done at the dialysis center or at home with training. Peritoneal dialysis is another procedure that removes extra water, wastes, and chemicals from your body. This type of dialysis uses the lining of your abdomen to filter your blood. This lining is called the peritoneal membrane and acts as the artificial kidney.
With peritoneal dialysis, a mixture of minerals and sugar dissolved in water, called dialysis solution, travels through a soft tube into your abdomen. The sugar, called dextrose, draws wastes, chemicals, and extra water from the tiny blood vessels in your peritoneal mem- brane into the dialysis solution. After several hours, the used solution is drained from your abdomen through the tube, taking the wastes from your blood with it. Then you fill your abdomen with fresh dialysis solution, and the cycle is repeated. The process of draining and refilling is called an exchange.
There are two types of peritoneal dialysis and both are usually performed by the patient without help from a partner. CAPD is a form of self-treatment that needs no machine. However, with CCPD, you need a machine to drain and refill your abdomen. The most common problem with peritoneal dialysis is peritonitis, a serious abdominal infection. This infection can occur if the opening where the catheter enters your body becomes infected or if contamination occurs as the catheter is connected or disconnected from the bags.
Unfortunately, dialysis does not cure kidney failure. Hemodialysis and peritoneal dialysis are treatments that help replace the work your kidneys did. These treatments help you feel better and live longer. Although patients with kidney failure are now living longer than ever, over the years kidney disease can cause problems such as heart disease, bone disease, arthritis, nerve damage, infertility, and malnutri- tion. These problems won't go away with dialysis. Guide to Causes of Renal Failure and Strokes Following Coronary Surgery by Anapol Schwartz Law Firm. 2007 All Rights Reserved.

Mach Learn (2010) 81: 333–357DOI 10.1007/s10994-010-5185-8 Learning to rank on graphs Received: 31 July 2008 / Revised: 27 December 2009 / Accepted: 28 March 2010 /Published online: 29 May 2010© The Author(s) 2010 Abstract Graph representations of data are increasingly common. Such representationsarise in a variety of applications, including computational biology, social network analysis,web applications, and many others. There has been much work in recent years on developinglearning algorithms for such graph data; in particular, graph learning algorithms have beendeveloped for both classification and regression on graphs. Here we consider graph learningproblems in which the goal is not to predict labels of objects in a graph, but rather to rankthe objects relative to one another; for example, one may want to rank genes in a biologicalnetwork by relevance to a disease, or customers in a social network by their likelihood ofbeing interested in a certain product. We develop algorithms for such problems of learningto rank on graphs. Our algorithms build on the graph regularization ideas developed in thecontext of other graph learning problems, and learn a ranking function in a reproducing ker-nel Hilbert space (RKHS) derived from the graph. This allows us to show attractive stabilityand generalization properties. Experiments on several graph ranking tasks in computationalbiology and in cheminformatics demonstrate the benefits of our framework.
