Background: Safety concerns have been expressed regarding the use of immature non-ejaculated spermatozoa for ICSI. Therefore, adverse health outcomes, birth parameters, major anomaly rates and chromosomal aberrations in children born after ICSI using testicular and epididymal sperm were investigated. Methods: Questionnaire data and Results: of physical examinations of 530 children born after ICSI with testicular sperm and of 194 children born after ICSI with epididymal sperm were compared with data on 2516 ICSI children born using ejaculated sperm. Results: Birth parameters, stillborn rates, prematurity rates and rates of low birthweight and very low birthweight were comparable between the non-ejaculated and the ejaculated sperm groups. The perinatal death rate was higher for twins but not for singletons in the non-ejaculated sperm group in comparison to the control cohort of children born using ejaculated sperm. A non-significant increase in major anomalies was reported in the non-ejaculated sperm group in comparison to the ejaculated sperm group. No more anomalies were observed in pre- and post-natal karyotypes from viable pregnancies established using non-ejaculated sperm versus ejaculated sperm.CONCLUSIONOverall neonatal health in terms of birth parameters, major anomalies and chromosomal aberrations in our large cohort of children born by the use of non-ejaculated sperm seems reassuring in comparison to the outcome of children born after the use of ejaculated sperm. © 2011 The Author.

BACKGROUND: Patients facing decisions should be told about their options, have the opportunity to discuss the pros and cons, and have their preferences reflected in the final decision. OBJECTIVES: To learn how decisions were made for two major preference-sensitive interventions. DESIGN: Mail survey of probability samples of patients who underwent the procedures. PARTICIPANTS: Fee-for-service Medicare beneficiaries who had surgery for prostate cancer or elective coronary artery stenting in the last half of 2008. MAIN MEASUREMENTS: Patients' reports of which options were presented for serious consideration, the amount of discussion of the pros and cons of the chosen option, and if they were asked about their preferences. RESULTS: The majority (64%) of prostate cancer surgery patients reported that at least one alternative to surgery was presented as a serious option. Almost all (94%) said they and their doctors discussed the pros, and 63% said they discussed the cons of surgery "a lot" or "some". Most (76%) said they were asked about their treatment preferences. Few who received stents said they were presented with options to seriously consider (10%). While most (77%) reported talking with doctors about the reasons for stents "a lot" or "some", few (19%) reported talking about the cons. Only 16% said they were asked about their treatment preferences. CONCLUSIONS: While prostate cancer surgery patients reported more involvement in decision making than elective stent patients, the reports of both groups document the need for increased efforts to inform and involve patients facing preference-sensitive intervention decisions. © Society of General Internal Medicine 2012.

Background. Transplantation rates are very low for the broadly sensitized patient (panel reactive antibody [PRA]980%; HS). Here, we examine the efficacy, outcomes, and cost-effectiveness of desensitization using high-dose intravenous immunoglobulin (IVIG) and rituximab to improve transplantation rates in HS patients. Methods. From July 2006 to December 2011, 207 HS (56 living donors/151 deceased donors) patients (donor-specific antibody positive, PRA980%) were desensitized using IVIG and rituximab. After desensitization, responsive patients proceeded to transplantation with an acceptable crossmatch. Cost and outcomes of desensitization were compared with dialysis. Results. Of the 207 treated patients, 146 (71%) were transplanted. At 48 months, patient and graft survival by KaplanYMeier were 95% and 87.5%, respectively. The total 3-year cost for patients treated in the desensitization arm was $219,914 per patient compared with $238,667 per patient treated in the dialysis arm. Thus, each patient treated with desensitization is estimated to save the U.S. healthcare system $18,753 in 2011 USD. Overall, estimated patient survival at the end of 3 years was 96.6% for patients in the desensitization arm of the model (based on Cedars-Sinai survival rate) compared with 79.0% for an age, end-stage renal disease etiology, and PRA matched group of patients remaining on dialysis during the study period. Conclusions. We conclude that desensitization with IVIG+rituximab is clinically and cost-effective, with both financial savings and an estimated 17.6%greater probability of 3-year survival associated with desensitization versus dialysis alone. However, the benefits of desensitization and transplantation are limited by organ availability and allocation policies. © 2013 Lippincott Williams & Wilkins.

In a previous study, meiotic activity was observed in human intratesticular xenografts from peripubertal patients. However, full spermatogenesis could not be established. The present study aimed to evaluate whether the administration of recombinant human FSH could improve the spermatogonial survival and the establishment of full spermatogenesis in intratesticular human xenografts. Human testicular tissue was obtained from six boys (aged 2.5-12.5 years). The testicular biopsy was fragmented and one fragment of 1.5-3.0 mm3 was transplanted to the testis of immunodeficient nude mice. Transplanted mice were assigned to different experimental groups to enable evaluation of the effects of FSH administration and freezing. The structural integrity of the seminiferous tubules, the spermatogonial survival and the presence of differentiated cells were evaluated by histology and immunohistochemistry. Freezing or administration of FSH did not influence tubule integrity and germ cell survival in human xenografts. Meiotic germ cells were observed in the xenografts. More tubules containing only Sertoli cells were observed in frozen-thawed grafts, and more tubules with meiotic cells were present in fresh grafts. There was no clear influence of FSH treatment on meiotic differentiation. Administration of FSH did not improve the establishment of full spermatogenesis after intratesticular tissue grafting. © 2012, Reproductive Healthcare Ltd. Published by Elsevier Ltd.

Liver transplant in the US remains a successful life-saving procedure for patients with irreversible liver disease. In 2012, 6256 adult liver transplants were performed, and more than 65,000 people were living with a transplanted liver. The number of adults who registered on the liver transplant waiting list decreased for the first time since 2002; 10,143 candidates were added, compared with 10,359 in 2011. However, the median waiting time for active wait-listed adult candidates increased, as did the number of candidates removed from the list because they were too sick to undergo transplant. The overall deceased donor transplant rate decreased to 42.3 per 100 patient-years, and varied geographically from 18.9 to 228.0 per 100 patient-years. Graft survival continues to improve, especially for donation after circulatory death livers. The number of new active pediatric candidates added to the waiting list also decreased. Almost 75% of pediatric candidates listed in 2009 underwent transplant within 3 years; the 2012 rate of deceased donor transplants among active pediatric wait-listed candidates was 136 per 100 patient-years. Graft survival for deceased donor pediatric transplants was 92.8% at 30 days. Medicare paid for some or all of the care for more than 30% of liver transplants in 2010.
