Stem cells from fat used to repair damaged skull
Surgeons in Germany have used stem cells derived from fat to regenerate nearly 19 square inches of damaged skull in a 7-year-old girl. Doctors at the Justus-Liebig-University Medical School in Giessen, Germany, recovered bone from the girl’s pelvis, milled it into chips about 0.1 inch long, placed the chips in the missing area of the skull, and added stem cells extracted from fat tissue in her buttocks. 
   

Stress contributes to skin cancer development in mice
Mice irradiated with ultraviolet B rays and then exposed to stress 14 days later developed skin cancer after just eight weeks, compared with 21 weeks for mice exposed to ultraviolet rays alone. The report, published in the December issue of the Journal of the American Academy of Dermatology, also showed that 35 percent of the stressed mice developed at least one tumor, compared with 7 percent of the control mice.
 

 
Protein discovered that causes stem cells to differentiate
Researchers at the University of California, San Diego, have discovered a protein in mice that allows embryonic stem cells to divide indefinitely while avoiding the duplication of genetically damaged cells that can lead to cancer. The report, published Dec. 26 in the online edition of the journal Nature Cell Biology, showed that this protein is activated by DNA damage and suppresses a gene that is necessary for stem cell self-renewal. 
     
South Korea allowing human stem cell research
Effective Jan. 1, researchers in South Korea are able to use fertilized eggs left over at fertility clinics to harvest stem cells for research, as authorized by guidelines passed by the South Korean cabinet. Scientists plan to use stem cell research to find cures for 18 diseases, including diabetes, Alzheimer’s disease, and cerebral palsy.
 

A Word from President Armand Keating, M.D.

I’m sure that over the years you’ve used algorithms to solve problems. But have you ever helped construct an algorithmic formula for others to use?

Let’s see if, together, we can create one that addresses the challenge of measuring quality outcomes in hematopoietic stem cell transplant programs. This algorithm will be for use by transplant physicians.

1. For the first box of our algorithm, we’ll use the statement, “Quality outcomes in  hematopoietic stem cell transplants (HSCT) are important,” and we’ll allow the user to choose YES or NO.

2. If YES is selected, an arrow will point to the next box that holds the statement, “Third-party payers for HSCT have an obligation to know whether the therapies they reimburse are achieving quality outcomes.” Again, we’ll permit a YES or NO answer.

3. The YES response, if chosen, can have an arrow pointing to a third box with the opinion, “Payers, sooner or later, can be expected to devise measures of quality outcomes for the purpose of differentiating contracted HSCT facilities from other facilities.” YES or NO.

4. The YES response will have an arrow leading to a final box that presents the statement, “Medical professionals who provide HSCT therapies are in the best position to develop measures of quality.” YES or NO.

Answer YES, and an arrow points to the conclusion: “You have an opportunity to assume a leadership role in defining quality outcomes that are meaningful to you and your patients.”

Or, answer NO and the arrow points to an alternative conclusion: “You risk all the hazards of inactivity, including compliance with outcomes criteria developed outside the HSCT community.”

In hematopoietic stem cell transplantation, the development of criteria for measuring quality outcomes is a thorny topic ... partly because our therapies are used across a diversity of malignancies, inherited diseases and bone marrow failure ... and partly because of the dramatic variations in patient variables, such as disease stage, co-morbidities and patient age. Also, the relatively small number of patients at individual transplant centers can make interpretation of outcomes data a daunting statistical challenge.

All these issues factor into a session planned for the Tandem BMT Meetings next month in Keystone, Colorado. In recent years, our annual meeting has included a session for BMT medical directors that takes up challenging topics. This year, the topic will be the search for definitions of quality outcomes and strategies for assuming the leadership role that the arrows point to in our algorithm.

The session begins at 1:30 p.m. on Sunday, Feb. 13. Although designed for BMT center medical directors, the session is open to all interested registrants.

The chair for the session, Dr. Roy Jones, already has a declared position: “It is my belief that we soon will be required to report aggregate outcomes data to an increasing variety of third-party and federal agencies. I believe now is the time to begin planning for how we will respond to those requests. If we leave the planning until the requests are made, we lose the opportunity to guide the nature and structure of such reporting.”

Roy treats patients at a large academic center. Other panelists will be clinicians from a smaller community center and a pediatric program. The session also will have input representing the solid organ transplant community, where outcomes reporting already is standard procedure.

Hearing what these speakers have to say is half of what the session is about. The other half is hearing from you. You’ll want to come prepared to give your thoughts about measuring outcomes of therapy and the strategies and pathways for addressing this most important and challenging issue.

– Cheers, Armand

  Highlights of ASH meeting in San Diego
Among the headlines of the American Society of Hematology annual meeting last month in San Diego were:
       • An update on umbilical cord blood transplantation
       • “Tregs” may hold a key to GvHD
       • New immunotherapy approaches may help in myeloid leukemias
       • Stroke Prevention II trial halted
       • New treatments heralded for multiple myeloma 

  Scientists stimulate stem cells to differentiate into red blood cells
A technique that involves exposing hematopoietic stem cells to stromal cells to provide an environment that mimics that of bone marrow, then adding erythropoietin, signals the stem cells to become red blood cells. According to a report published Dec. 26 in the online edition of the journal Nature Biotechnology, this technique, develop in mice by researchers at the University of Paris in France, could be applied in humans.


  Scientists create embryonic stem cell-like cells from neonatal mouse testes
Researchers at Kyoto University in Japan have established a line of multipotent cells similar to stem cells using cultures from neonatal mouse testes. According to a report published Dec. 29 in the online edition of the journal Cell, these cells can transform into blood-forming cells, vascular cells and beating heart muscle cells.


  Inhibiting the Hedgehog pathway may not be effective treatment for basal cell carcinoma
In mice, deactivating the Gli2 component of the Hedgehog signaling pathway in basal cell carcinoma did not stop the growth of all tumor cells, according to an advance online report in the journal Genes & Development. In addition, once Gli2 is reactivated, tumor growth sometimes resumes, indicating not all tumors die when the pathway is interrupted.

  FDA approves therapy for severe oral mucositis
Based on a priority review, the FDA has approved Kepivance (palifermin) for decreasing the incidence and duration of severe oral mucositis in patients with hematologic cancers undergoing high-dose therapy, with or without radiation, followed by a blood stem cell transplant. Kepivance was shown to be safe and well-tolerated in a Phase 3 study published in the Dec. 16 issue of the New England Journal of Medicine. 
  Genzyme Corp. completes acquisition of ILEX Oncology Inc.
Genzyme Corp. in Cambridge, Mass., has acquired cancer drug developer ILEX Oncology Inc. in San Antonio, Texas, in a stock-for-stock deal valued at $1 billion. ILEX’s products include Campath for treating B-cell chronic lymphocytic leukemia, and clofarabine, which is nearing FDA approval.

  Agencies coordinate bioterrorism emergency response
ASBMT convened a meeting of representatives of public sector agencies and health professional associations for coordination in the event of a bioterrorist strike involving radiological or nuclear mass casualties. The meeting, held during last month’s American Society of Hematology convention in San Diego, considered the role, capabilities and responsibilities of each participating organization and agency and decided on several next steps for joint planning.  

  Today is the housing deadline for Keystone
The housing deadline is today for the 2005 Tandem BMT Meetings in Keystone, Colo. Registration and housing information are available on the ASBMT Web site, or click the link below. Some categories of housing already are full as pre-registration indicates another year of record attendance. After today, special group rates will be honored, but on a space-available basis. Remember that most of the housing at Keystone is rented condominiums. Meeting registrants often achieve savings by jointly reserving two-, three- and four-bedroom units.

  ASBMT voices strong support for embryonic stem cell research
The ASBMT Board of Directors has adopted policy strongly supporting federal funding for embryonic stem cell research. “The advantages and limitations of these cells are poorly understood, and their therapeutic role compared with adult stem cells, which have been studied in greater detail, is unknown,” the Society policy statement said.  

  Deadline for annual mail ballot is Jan. 14
Ballots have been mailed to ASBMT members for the annual election of officers and directors. As customary, at least two candidates have been nominated for each open position, which this year are vice president and three directors. Ballots must be received in the ASBMT Executive Office by the close of business on Jan. 14.

  86 applicants accepted for membership in December
The largest-ever class of applicants was brought into ASBMT membership when the Board of Directors met last month in San Diego. Included were 13 members, two associate members, 16 affiliate members and 55 in-training members -- bringing the Society’s total enrollment to 1,155. Effective Jan. 1 this year, dues have been reduced by $50 in the member, associate and affiliate categories. The society’s membership application is online at the ASBMT Web site.  

  Free ASBMT membership for trainees
Post-doctoral fellows and physicians-in-training for blood and marrow transplantation are eligible for free ASBMT membership. The annual dues are being waived for trainees who apply for membership in the Society, a program made possible by a grant from ESP Pharma.

  Medical directors to consider quality outcomes measurements
The annual conference of BMT medical directors is scheduled for 1:30 p.m. to 3 p.m. Feb. 13, during the 2005 Tandem BMT Meetings in Keystone, Colo. The topic this year will be strategies for measuring quality of treatment outcomes in transplant programs. Panelists will include representatives of academic and community-based transplant programs, both adult and pediatric. The program is open to all Tandem BMT Meeting registrants.

  Panel will examine FDA’s new ‘Good Tissue Practice’ rule
The Food and Drug Administration’s recently published Good Tissue Practice rule will be the focus of an intensive one-hour examination from 3 p.m. to 4 p.m. Feb. 13, at the 2005 Tandem BMT Meetings in Keystone, Colo. Richard Champlin, M.D., will moderate a panel that includes representatives of FDA staff and BMT laboratory and clinical practice.

  Record number of symposia scheduled for Keystone
A record 14 satellite symposia will be held in conjunction with the 2005 Tandem BMT Meetings, Feb. 10-14, in Keystone, Colo. A list of the symposia, dates and sponsors is online. 

  Travel grants announced for Tandem BMT Meetings
The ASBMT Board of Directors has awarded 31 travel grants of $1,000 each to the young investigators invited to give oral presentations at the 2005 Tandem BMT Meetings. This year, 31 of the 57 oral abstracts will be presented by young investigators -- those not more than five years past an M.D. or PhD degree.

  Special session for trainees at Tandem BMT Meetings
A workshop for physicians-in-training and post-doctoral fellows in blood and marrow transplantation will be held on the first day at the 2005 Tandem BMT Meetings in Keystone, Colo. The first part of the workshop will be a “user’s guide” for trainees attending the meetings for the first time. Recommendations will be offered on which sessions to attend, how to participate and what to take away from the sessions. The workshop will also include small-group discussions with senior transplanters on career opportunities and alternatives. The session is scheduled for 2 p.m. to 3:30 p.m. on Feb. 10.

  First joint American-Israeli conference on cancer
ASBMT is a co-sponsor of the inaugural Joint American-Israeli Conference on Cancer that will be held March 16-18 in Jerusalem. The conference is being organized by the University of Miami Sylvester Comprehensive Cancer Center and Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins. The deadline for abstracts is Jan. 15. 

  12 new appointments to Editorial Board
The ASBMT Board of Directors has appointed 12 new members to the Editorial Board for Biology of Blood and Marrow Transplantation, replacing a similar number of retiring board members. Announcing the new board members was Editor-in-Chief Robert Korngold, Ph.D. 

  BBMT features study of cytokines and engraftment
This month’s issue of Biology of Blood and Marrow Transplantation presents a study of cytokines and cytotoxic pathways in engraftment resistance to purified allogeneic hematopietic stem cells (HSC). Christian Scheffold, M.D., and colleagues at Stanford University School of Medicine show in mouse research that elimination of selected cytokines does not alter allogeneic hematopoietic resistance. The chimerism data reinforce the importance of competition for HSC niches in conjunction with immune mechanisms on resistance to long-term HSC engraftment. 

  Aid for humanitarian crisis in Southeast Asia
Many organizations are mobilizing to provide emergency assistance to victims of the earthquake and tsunami that has devastated parts of Southeast Asia. The American Institute of Philanthropy, a charity watchdog, rates nonprofit groups with a letter grade of A+ to F. Eight of the relief organizations providing aid to Southeast Asia victims have earned an “A” or “A+” grade, based on the portion of their budget going to program services and their fundraising efficiency.
