Plasma somatostatin response to food and the administration of the long-acting somatostatin analogue SMS 201-995, as well as pituitary responses to insulin-induced hypoglycemia, growth hormone-releasing hormone (GHRH) and thyrotropin-releasing hormone (TRH), were assessed in a 60-year-old woman with biopsy-proven metastatic somatostatinoma. SMS 201-995 alone did not change plasma somatostatin-like immunoreactivity (SRIF), but levels of low-molecular-weight forms (SRIF-14 and SRIF-28) more than doubled in response to a standard meal. This postprandial response was not affected by pretreatment with SMS 201-995. Although a growth hormone response to insulin-induced hypoglycemia and supramaximal GHRH was absent, the patient's thyroid-stimulating hormone response to TRH was normal. These results suggest that somatostatin analogues may not influence tumor autonomy and that a SRIF response to food may contribute to early satiety in patients with somatostatinoma. In addition, the long-term use of somatostatin analogues to suppress hormone production by other peptide-secreting tumors may not have predictable results. 相似文献

Lepidapedon sereti n. sp. is described from the macrourid Coelorinchus sereti from the deep water off Vanuatu. It is placed in the Elongatum group and Elongatum subgroup. It differs from the other species described in this subgroup by the distinctly dorsally subterminal excretory pore. It also differs from other species in combinations of size, excretory vesicle length, proportions of forebody, post-testicular region and other metric features. This constitutes the first record of a Lepidapedon (sensu stricto) from the Central Western Pacific Ocean. 相似文献

Objectives
The conference objectives included educating patients and advocates about clinical trials, educating the clinical research community about patient perspectives on participating in clinical trial design, and identifying strategies to increase participation in clinical trial design for neurological disorders.Design
Observations were noted during a 1‐day conference attended by patients, patient advocates, clinical trial staff, and investigators. The conference offered didactic sessions, small, and large group discussions.Participants
Conference participants were patients, patient advocates, clinical trial staff, students, and investigators interested in engaging patients in clinical trial design for neurological disorders.Measures
Conference participants were asked to consider lessons learned that could increase patient engagement in clinical trial design.Results
We found that there is growing interest in including patients in the design of clinical trials for neurological disorders. Several themes emerged on how to move forward: networking; the multifaceted roles of advocates in research; training and education; creating patient–researcher partnerships; and clinical trials regulation issues.Conclusions
The conference provided a forum for dialogue regarding stakeholder engagement in the design of clinical trials for neurological disorders. This experience provides a template for replication and dissemination of this conference and informs next steps to accelerate the pathway from dialogue to action. 相似文献68.

Vascularized composite allotransplantation (VCA) has emerged as a viable limb replacement strategy for selected patients with upper limb amputation. However, allograft rejection has been seen in essentially all reported VCA recipients indicating a requirement for substantial immunosuppressive therapy. Calcineurin inhibitors have served as the centerpiece agent in all reported cases, and CNI‐associated complications associated with the broad therapeutic effects and side effects of calcineurin inhibitors have been similarly common. Recently, belatacept has been approved as a calcineurin inhibitor replacement in kidney transplantation, but to date, its use in VCA has not been reported. Herein, we report on the case of a hand transplant recipient who developed recurrent acute rejection with alloantibody formation and concomitant calcineurin inhibitor nephrotoxicity, all of which resolved upon conversion from a maintenance regimen of tacrolimus, mycophenolate mofetil and steroids to belatacept and sirolimus. This case indicates that belatacept may be a reasonable maintenance immunosuppressive alternative for use in VCA, providing sufficient prophylaxis from rejection with a reduced side effect profile, the latter being particularly relevant for nonlife threatening conditions typically treated by VCA. 相似文献
