RESUMO

Ethicists and guidelines have suggested that potential living kidney donors who withdraw from evaluation be offered an 'alibi.' We sought to determine what potential living kidney donors are told about their ability to opt out, alibi availability and postwithdrawal confidentiality. We reviewed 148 consent forms for living kidney donor evaluation from US transplant centres that performed >5 living kidney transplants in 2010-2011 (response rate 87%). We found that while 98% of centres used evaluation consent forms that indicated that the donor could withdraw, only 21% of these documents offered an alibi. Another 23% of centres' consent forms indicated that the transplant team would be willing to inform the intended recipient that an individual was not a potential donor. Relatively few consent documents explicitly addressed the confidentiality of the donor's health information (31%), candidacy status (18%), decision (24%) or reasons (23%) following withdrawal. To preserve potential donors' autonomy and relationships, we advocate that all transplant centres offer general alibis in their evaluation consent forms. We conclude by offering recommendations for evaluation consent discussions of opting out, alibis and postwithdrawal confidentiality.

RESUMO

UNLABELLED: Osseous genioplasty is a versatile technique to improve chin and facial aesthetics. It carries several benefits compared to an alloplastic implant, but the downsides of an intersegmental gap and lateral stepoffs must be weighed. These areas are typically left open, despite being subject to unpredictable resorption or incomplete osseous healing. We describe the strategy of using a combination of demineralized bone matrix (DBM) and fibrin glue to promote bone fill while smoothing contours and transitions along the genioplasty. Our retrospective study included 32 patients who underwent genioplasty with the DBM-fibrin sandwich. There were no genioplasty-related complications at the 6 months follow-up. Our results indicate that this technique is safe and is a valuable addition to possible graft material for genioplasty.

RESUMO

We examined written informed consent forms for living liver donor evaluations to determine whether they incorporated elements required by the Centers for Medicare and Medicaid Services (CMS) and suggested by the Organ Procurement and Transplantation Network (OPTN). We contacted each of the 41 US centers that performed at least 1 living donor liver transplant in 2011; 37 centers reported active living donor evaluation programs. Twenty-six centers shared their consent form for living donor evaluation (response rate = 70%). Each document was double-coded for consent element content. We found that 57% of the centers included the 9 mandated CMS elements. Although the OPTN guidelines are non-binding, 78% of the centers used consent forms that addressed at least two-thirds of the elements recommended by OPTN. Only 17% of the centers provided written offers of an alibi to donors who withdrew from the evaluation. On the basis of our findings, we offer suggestions that may be relevant to ongoing revisions to the OPTN living liver donor consent policy and may help centers to improve the clarity of their written consent forms.

RESUMO

The theme of the 2013 Yale Healthcare Conference was "Partnerships in Healthcare: Cultivating Collaborative Solutions." The April conference brought together leaders across several sectors of health care, including academic research, pharmaceuticals, information technology, policy, and life sciences investing. In particular, the breakout session titled "Taking R&D Back to School: The Rise of Pharma-Academia Alliances" centered on the partnerships between academic institutions and pharmaceutical companies. Attendees of the session included members of the pharmaceutical industry, academic researchers, and physicians, as well as graduate and professional students. The discussion was led by Dr. Thomas Lynch of Yale University. Several topics emerged from the discussion, including resources for scientific discovery and the management of competing interests in collaborations between academia and the pharmaceutical industry.

RESUMO

RNA silencing in Caenorhabditis elegans is transmitted between cells by the transport of double-stranded RNA (dsRNA). The efficiency of such transmission, however, depends on both the cell type and the environment. Here, we identify systemic RNAi defective-3 (SID-3) as a conserved tyrosine kinase required for the efficient import of dsRNA. Without SID-3, cells perform RNA silencing well but import dsRNA poorly. Upon overexpression of SID-3, cells import dsRNA more efficiently than do wild-type cells and such efficient import of dsRNA requires an intact SID-3 kinase domain. The mammalian homolog of SID-3, activated cdc-42-associated kinase (ACK), acts in many signaling pathways that respond to environmental changes and is known to directly associate with endocytic vesicles, which have been implicated in dsRNA transport. Therefore, our results suggest that the SID-3/ACK tyrosine kinase acts as a regulator of RNA import into animal cells.
