Self-everting ileostomy

OBJECTIVE

Self-everting ileostomy.

METHOD

After delivering the small bowel through the trephine wound the bowel is opened and with time the mucosa migrates to the skin edge forming a spouted ileostomy.

RESULTS

Five patients underwent the self-everting ileostomy with no stomal complications experienced. The end result is indistinguishable from a primarily sutured stoma.

CONCLUSION

The self-everting ileostomy can be a useful technique to get out of a difficult situation.

Barriers to participation in breast cancer trials

6593

Background: Clinical cancer trials allow investigators to test the effectiveness and safety of new cancer drugs and treatments. Historically, fewer that 5% of cancer patients have participated in clinical trials. The purpose of this study was to assess attitudes, beliefs, and practical barriers to clinical trial recruitment. Methods: Women were recruited in the Herbert Irving Comprehensive Cancer Center while waiting for routine breast screening or for oncology care in connection with a diagnosis of breast cancer. The 29-item survey questionnaire covered demographic factors, prior cancer diagnosis or risk factors, past experience with clinical trials if any, willingness to participate in different types of trials, and attitudinal and practical barriers to participation. Results: Of 329 respondents, 48.9% were non- Hispanic white, 10.9% non-Hispanic black, 34.9% Hispanic, and 5.30% other/unknown. The mean age of participants was 52.5 (SD=12.1). Of 131 (39.8%) participants reporting that they had been asked to participate in clinical trial, 82 were white, 17 black and 32 Hispanic. Of those who enrolled, 64 were white, 14 were black, and 19 Hispanic. Of those asked to participate 56/63 breast cancer patients (88.9%) and 44/68 others (64.7%) enrolled (P=0.002). Of 48 who reported that they had child care responsibilities, 33 enrolled (68.8) compared to 67/83 (80.7%) of those without such responsibilities (P=0.07). Of the total sample, 88/220 (40.0%) of those without childcare responsibilities but only 32/109 (29.4) said they would be willing to participate in a placebo-controlled trial. Respondents were twice as likely to say they would participate in a trial comparing two active agents as a placebo-controlled trial. Conclusion: Our findings suggest that being asked to participate in a clinical trial may be associated with demographic factors, and that specific circumstances, such as child care responsibilities, may also affect trial participation. Awareness of these barriers may help investigators to develop effective strategies for overcoming them and for improving trial participation overall.

The NCI pediatric central institutional review board (PedCIRB) initiative: Progress and impact

6632

NCI has developed a central IRB (PedCIRB) to review NCI-sponsored pediatric clinical trials conducted by the Children's Oncology Group (COG). COG comprises ∼200 U.S. medical institutions and protocol activation traditionally requires separate protocol review by each local IRB (LIRB) and, subsequently, a review of each protocol amendment and significant adverse event. The PedCIRB model seeks to increase patient protection by improving the expertise of protocol reviewers and making their review available to all PedCIRB participating institutions. The PedCIRB consists of experts in pediatric oncology, pediatric medicine, nursing, pharmacy, bioethics, biostatistics, as well as patient advocates and childhood cancer survivors. The PedCIRB model also eliminates redundant reviews, reduces administrative burdens on local COG investigators and LIRBs, and can accelerate the pace of local protocol activation, thus increasing the availability of clinical trials to children with cancer. The PedCIRB conducts a full board protocol review that is available via a confidential website to participating LIRBs. LIRBs can choose to perform a facilitated review, using PedCIRB materials, that focuses on local concerns, rather than a full LIRB protocol review. If the LIRB accepts the PedCIRB review, the PedCIRB becomes the IRB of record for that protocol and takes responsibility for the review of subsequent protocol amendments, adverse events and continuing reviews. Since starting in November 2004, the PedCIRB has reviewed 59 protocols. Initial reviews resulted in 44 approvals pending modification and 15 protocols being tabled for further information. The time from protocol submission to final approval by the PedCIRB has ranged from 3 to 28 weeks with an average time of 16.9 weeks during year one and 12.7 weeks during year two of the project. As of November 2006, 117 of a possible 197 U.S. COG institutions (59%) have signed on to the PedCIRB initiative and 70% of the participating institutions have conducted facilitated reviews (total 750) for the 30 protocols available on the PedCIRB website. The PedCIRB's influence on protocol development and patient accrual timelines will be discussed.

Comparison Between Clinical and Histopathological Scoring in Cadaveric Kidney Transplantation and Its Correlation With Posttransplant Evolution

INTRODUCTION

There are several scoring systems, both clinical (Deceased Donor Score [DDS]) and histopathological (Remuzzi [REM]), that attempt to determine acceptability criteria for deceased donor kidney transplant. A retrospective study was performed among a group of kidney transplant recipients to evaluate posttransplant evolution with clinical and histopathological scores.

MATERIALS AND METHODS

Among 107 first deceased donor kidney transplant patients, 95 had undergone a pretransplant biopsy. Donor age was 38.46 +/- 16.9 years; recipient age: 49.2 +/- 16.3 years; DDS was 15.58 +/- 7.29. REM was 2.89 +/- 1.7. Delayed graft function was 64.2%. Induction therapy was administered to 49.5%. Cold ischemia time (CIT) was 1364 +/- 348 minute. Time on dialysis was 2275 +/- 1501 days. Induction therapy, immunosuppressive regimens, CIT, and time on dialysis were not significantly different among the groups. One-year patient and graft survival were 94.5% and 86%, respectively and 2-year values, 92.6% and 81%, respectively.

CONCLUSION

DDS showed a significant correlation with serum creatinine values over 1 and 2 years. REM did not show a significant association with any events. The differences were sustained after adjusting for other variables. Graft survival maintained a strong correlation with DDS categories and no association with REM. The clinical characteristics of a deceased donor appeared to be of greater importance than the biopsy findings in terms of posttransplant events.
