Postoperative PSA And PSA Velocity Identify Presence Of Prostate Cancer After Various Surgical Interventions For Benign Prostatic Hyperplasia
UroToday.com - Men undergoing surgical interventions for BPH are still at risk for subsequent development of prostate cancer (CaP) due to residual tissue. It is suggested that PSA decreases approximately 0.1-0.3ng/ml for every 1g of prostate tissue removed. In the online edition of Urology, Dr. Brian Helfand and associates determined the PSA values and PSAV in patients who had undergone TURP, holmium laser resection of the prostate (HoLRP), or open prostatectomy (OP) for treatment of BPH and compare these values in patients with histologic BPH only with the values in those with incidentally found CaP.

DNA Computation Gets Logical At The Weizmann Institute Of Science
Biomolecular computers, made of DNA and other biological molecules, only exist today in a few specialized labs, remote from the regular computer user. Nonetheless, Tom Ran and Shai Kaplan, research students in the lab of Prof. Ehud Shapiro of the Weizmann Institute"s Biological Chemistry, and Computer Science and Applied Mathematics Departments have found a way to make these microscopic computing devices "user friendly," even while performing complex computations and answering complicated queries.

Rep. Schwartz Introduces Legislation To Establish AAMC-Proposed Health Care Innovation Zones

The AAMC (Association of American Medical Colleges) applauds Rep. Allyson Schwartz (D-Pa.) for introducing legislation (H.R. 3134) to establish pilot "health care innovation zones" (HIZs) building on the strengths of academic medical centers (AMCs). The legislation creates and tests these zones around the country with the goal of improving patient outcomes, while slowing the growth of health care costs. "Our nation faces a complex health care crisis of access, quality and cost, and there is an urgent need to design and test large scale, innovative models to transform the way we deliver and pay for care," said AAMC President and CEO Darrell G. Kirch, M.D. "The AAMC wants to thank Rep. Schwartz for introducing this legislation, which will enable providers to truly reform delivery systems and improve the health of communities." The HIZs would include an academic medical center-a medical school, faculty physicians, and teaching hospitals-and community partners that provide the full spectrum of health care, such as inpatient, outpatient, post-acute, and preventive services to patients, as well as Medicare beneficiaries. Within the zones, alternative payment structures that reward quality and outcomes, rather than units of service, would be promoted. Planning grants would first be awarded to design innovation zones that improve quality, decrease costs, and train the next generation of physicians, nurses, and other health professionals in new models of cost-effective, quality health care. The HHS secretary would then establish innovation zones in communities across the country to test the ability of HIZs to increase provider integration, improve health care services, and reduce costs. The demonstration projects would operate for a period of at least three years, subject to renewal. Association of American Medical Colleges
