Researchers Announce Medical Breakthrough With Simple, Inexpensive Blood Test For Colon Cancer

Medical researchers with EDP Biotech Corporation (EDP) have captured national attention with their revolutionary new technology for a simple blood test to detect early-stage colon cancer.


Following the success of its pre-clinical trials for the ColoMarker(TM) assay, EDP has filed a patent on the biomarker, CA11-19, and all aspects of its use. Via an inexpensive blood test, ColoMarker(TM) will detect colon cancer in its earliest, most curable stages.


"American Cancer Society statistics show that when colon cancer is detected in its early stages, more than 90% of patients will survive. If not detected until the later stages, fewer than 10% will survive. ColoMarker(TM) detects colon cancer in these early, highly curable stages," says Kevin Jones, Ph.D., Chief Scientific Officer of EDP.


According to American Cancer Society statistics, fewer than 20% of Americans over the age of 50 who should be screened for colon cancer, actually are. With the use of ColoMarker(TM), a simple and inexpensive blood test, the number of people being screened would likely increase dramatically, leading to a decline in deaths due to colon cancer.


In pre-clinical trials, ColoMarker(TM) successfully detected the early stages (I, II, and III) of colon cancer. In tests of 2,370 blood samples, ColoMarker(TM) showed an accuracy rate of >99% for detecting colon cancer in these early stages. "ColoMarker(TM) could lead to a radical shift in the way we detect colon cancer," adds Dr. Jones.


National researchers who study colorectal cancer are closely monitoring emerging technologies such as ColoMarker(TM). Their findings are encouraging; just last week, the American Cancer Society, the National Cancer Institute, the Centers for Disease Control and Prevention and the North American Association of Central Cancer Registries released an optimistic report about the expected decline in deaths from colon cancer due to anticipated improvements in early screening methods.


Dr. Jones states, "The use of ColoMarker(TM) as a screening test could save tens of thousands of American lives every year and billions of dollars in healthcare costs." EDP Biotech is now moving forward expeditiously to get ColoMarker(TM) through the Food and Drug Administration clearance process.

St. Jude Medical Announces U.S. Launch Of TigerWire Steerable Guidewire

St. Jude Medical, Inc. (NYSE:STJ) announced U.S. launch of the TigerWire(TM) Steerable Guidewire. The newest member of the St. Jude Medical GuideRight(TM) family of steerable guidewires, the TigerWire Steerable Guidewire is designed to enhance physicians' ability to steer through challenging peripheral arteries, the vessels that supply blood to the legs and arms.


A guidewire is a thin, flexible wire that physicians use to help guide and steer a catheter (a flexible tube) through the arteries. Catheters are used to assist in diagnosing and treating blockages caused by a build-up of plaque inside artery walls. Plaque build-up can block blood flow and lead to heart attack or stroke.


The TigerWire Guidewire's tip is designed with enhanced flexibility to aid in navigation through the vessels. Its supportive design provides distinct zones of flexibility that make it easier for physicians to track and position the guidewire through challenging anatomy.


"The TigerWire Steerable Guidewire has been engineered for improved steerability," said Frank Callaghan, president of the St. Jude Medical Cardiovascular Division. "It gives physicians a tool that can ease access to difficult-to-reach vessels when performing complex diagnostic and interventional procedures."


The insertion of a guidewire is a first step in interventional procedures in which physicians thread catheters through the arteries to diagnose the severity of disease or deliver treatments, including devices such as stents that open blockages and restore blood flow.


Each year, an estimated 4 million cardiovascular catheterization procedures are performed in the U.S., according to IMV, a research and publishing firm specializing in the medical imaging and clinical diagnostic instruments markets.

MOM, Metal Ions And Lymphopenia

Metal-on-metal hip replacement and resurfacing have become the most commonly used type of procedure in the United Kingdom for patients who are < 60 years of age with osteoarthritis. Therefore, this research consisted of a cross-sectional study with analysis of demographic, clinical and laboratory characteristics of patients who had undergone metal-on-metal hip resurfacing, ceramic-on-ceramic and metal-on-polyethylene hip replacement to assess whether there was a relationship between MOM replacements and circulating metal ions in the blood, and absolute numbers of circulating lymphocytes.


There were 164 patients in the study, of which 106 had MOM hips, all were aged < 65 years and had pre-operative diagnosis of osteoarthritis and no pre-existing immunological disorders. Patients were excluded if their replacement had taken place less than six months previously, thereby avoiding the high-wearing, bedding-in phase. Blood samples were taken using a plastic needle cannula to avoid metal contamination.


The results showed that 'there were significant differences in the levels of metal ions in the whole blood and in the absolute lymphocyte counts'. A group of 10 patients of the 106 from the MOM group had circulating levels of chromium greater than 5 parts per billion. Therefore, the authors conclude that 'patients with MOM hips had reduced peripheral blood counts of T-lymphocytes in particular and B-lymphocytes when compared with control subjects with hip replacements which did not produce metal wear debris'. Although the effect of reduced lymphocytes is unknown, there has been a link between high levels of cobalt and chromium and DNA damage of lymphocytes and the authors recommend that long-term studies need to be conducted to determine whether the moderate lymphopenia associated with MOM hip replacements is detrimental or even beneficial to longevity of the replacement.

Racial Differences In Risk Factors For Venous Thromboembolism And Pulmonary Embolism

A new study of 1,960 White-Americans and 368 Black-Americans with objectively diagnosed venous thromboembolism (VTE) showed that, compared to Whites, Blacks had a significantly higher proportion with pulmonary embolism (PE), including idiopathic PE among Black women, and a significantly higher proportion of Blacks with VTE were women (71% vs 61% for Whites) The study is published in the American Journal of Hematology.



VTE is blood clots in veins and consists of deep vein thrombosis (DVT), a blood clot in the "inner" or "deep" vein, typically of the leg or pelvis, and its complication, PE, a dislodged DVT that has traveled with the returning blood to the heart and become lodged in the lungs. Most epidemiologic studies of VTE risk factors have been conducted within White-American and -European populations. However, compared to Whites, Black-Americans appear to have a higher risk and incidence of VTE. Two single nucleotide polymorphisms (DNA sequence variations), factor V Leiden (G1691A) and prothrombin (G20210A), have been identified as risk factors for DVT and PE in Europeans and White-Americans, but not Black- Americans.



"VTE appears to be more common in Blacks than Whites, but while we have identified many inherited causes for VTE in Whites, no such inherited causes in Blacks have been identified," said lead researcher Prof. John Heit, of the Mayo Clinic College of Medicine, Minnesota, USA. "We wondered whether Blacks were more likely to have VTE related to common exposures that can cause VTE, such as major surgery, hospitalization for acute medical illness, trauma, fracture, or birth control pills, to account for VTE being more common in Blacks, but this does not appear to be the case. Thus, we now question whether Blacks may have some as yet unidentified inherited cause for VTE."



The researchers found that, compared to Whites with VTE, Blacks with VTE have a higher proportion of PE events, a lower proportion of VTE related to transient risk factors and a higher proportion with idiopathic VTE, i.e. from a seemingly unknown or unrelated cause.



Blacks had a significantly higher mean BMI, and a significantly lower proportion with recent surgery, trauma or infection, family history of VTE and documented thrombophilia. Conversely, Blacks had a significantly higher proportion with hypertension, diabetes mellitus, chronic renal disease and dialysis, HIV and sickle cell disease. Compared to White women, Black women had a significantly lower proportion with recent oral contraceptive use or hormone therapy



"Given the poor survival after PE, our finding of an increased prevalence of PE among Blacks (particularly idiopathic PE) is disturbing, especially when coupled with previous reports of increased complications after VTE and higher PE case-fatality among Blacks," added Heit.



The study is accompanied by an editorial by Dr. Samuel Goldhaber of Brigham and Women's Hospital and Harvard Medical School, Boston, USA.

New Clinical Study Shows RyMed InVision-Plus&reg; IV Connector Dramatically Reduced Catheter-Related Bloodstream Infections By Over 92%

Georgia Health Sciences University, Augusta, GA exhibited a poster at the recent 11th National Conference on Cancer Nursing Research in Los Angeles, in which their clinical study showed RyMed Technologies' zero displacement InVision-Plus® IV Connector significantly decreased the incidence of catheter-related bloodstream infections (CR-BSIs) by 92.6% on average when compared to a simple split septum with negative displacement IV connector (Becton-Dickinson Q-Syte®) and a reversed split-septum device with negative displacement IV connector (ICU Medical Clave®). No clinical studies have been published comparing different types of connectors in oncology patients on CR-BSIs. CR-BSIs can cause treatment delays, add time to nursing care, increase costs, increase mortality and decrease quality of life for the patient and family.


The purpose of the study was to determine infection rates for a split septum valve, a negative reversed split-septum valve and an intraluminal protection device (IPD) with zero displacement in both critical care and medical in-patient oncology patients.


Detailed results:



-- CR-BSI incidences decreased 96.3%, from 2.9 to 0.1 infections per 1,000 catheter days, when the RyMed InVision-Plus® needleless IV connector was used compared to the Becton-Dickinson's Q-Syte® product.



-- CR-BSI incidences decreased 88.9%, from 3.7 to 0.4 infections per 1,000 catheter days, when the RyMed InVision-Plus® needleless IV connector was used compared to the ICU Medical Clave® product.



-- Overall, 92.6% decrease in infection rate was found when using the RyMed InVision-Plus® with Neutral Advantage™ technology.


Leading the study was Dr. Cynthia C. Chernecky PhD, RN, AOCN, FAAN, Jennifer Waller, PhD both from Georgia Health Sciences University; and Denise Macklin, BSN, RNC.


Dr. Chernecky stated, "Decreasing infections is essential to quality nursing care in oncology. The use of best product when added to other nursing interventions is essential as it can enable best outcomes for treatments and ultimately quality of life and a decrease in mortality".


"This new clinical data continues to demonstrate the superior design features of RyMed's InVision-Plus® needleless IV connector technology and how they have a significant positive patient safety impact among the cancer patient population," said Dana Wm. Ryan, President & CEO, RyMed Technologies, Inc.


This poster presentation by Dr. Chernecky was preceded by another in which she highlighted similar success by the RyMed product in decreasing intraluminal thrombotic occlusions compared to a negative displacement mechanical valve. Additionally, Chernecky also delivered a podium presentation discussing new data on the apparent ineffectiveness of other silver coated needleless IV connectors.


Catheter-related bloodstream infection (CR-BSI) continues to be one of the most frequent hospital acquired infections (HAIs) reported by hospitals nationwide. It has been reported that a patient that develops a CR-BSI could die up to 25% of the time, and the industry is discovering that RyMed's InVision-Plus® technology with zero fluid displacement is going to save many lives.
