The Carbomedics Prosthetic Heart Valve is a new bileaflet pyrolite carbon prosthesis. This paper reports the preliminary results in 40 patients who underwent mitral valve replacement (MVR) using the Carbomedics Valve in 1988. The operative mortality rate was 5% and the early results have been encouraging, with no valve related complications observed in the first post-operative year. 相似文献

The recommended dose of Vitamin E in human pregnancy is 22-30 mg/day. High doses of Vitamin E (>or=400 IU/day) have been shown to attenuate or even prevent the damaging effect of ethanol and diabetes on the fetus in experimental animal models. The Motherisk program prospectively enrolled, and followed-up on, 82 pregnant women exposed to high doses (>or=400 IU/day) of Vitamin E during the first trimester of pregnancy. Pregnancy outcome was compared to a matched control group. The study group (n=82) was exposed to Vitamin E at doses ranging from 400-1200 IU/day. There was one pregnancy with major malformation (omphalocele) in study group. There was an apparent decrease in mean birth weight (3173+/-467 g) in Vitamin E group as compare to control (3417+/-565 g; P=0.0015); however, there were no significant differences in rates of live births, preterm deliveries, miscarriages and stillbirths. Therefore, it is concluded that consumption of high doses of Vitamin E during the first trimester of pregnancy does not appear to be associated with an increased risk for major malformations, but may be associated with decrease in birth weight. 相似文献

Thrombophilia associated with anti-CD154 monoclonal antibody treatment and its prophylaxis in nonhuman primates 总被引:6,自引:0,他引:6

BACKGROUND: The authors previously reported thromboembolic complications associated with anti-CD154 monoclonal antibody (mAb) treatment in nonhuman primates. The underlying mechanisms of this complication and its management have not been established. METHODS: Eighty cynomolgus monkey renal allograft recipients treated with anti-CD154 mAb were studied for the incidence of thrombosis and its prophylaxis. RESULTS: Without anticoagulation prophylaxis, thromboembolic complications were seen in 5 of 11 recipients. With addition of perioperative heparin, the incidence was decreased to 2 of 10. No further improvement was observed by adding intraoperative prostaglandin (PG) E1. However, addition of ketorolac tromethamine to PGE1 and heparin decreased the incidence of thrombosis (one of eight). Most recently, the authors have found that ketorolac administration alone resulted in no thrombosis in 25 consecutive recipients. CONCLUSIONS: Ketorolac is remarkably effective in preventing thromboembolism associated with anti-CD154 mAb treatment, suggesting the mechanism underlying this complication may be related to platelet activation leading to enhanced aggregation. 相似文献

Aspirin consumption during the first trimester of pregnancy and congenital anomalies: a meta-analysis 总被引:5,自引:0,他引:5

OBJECTIVE: The purpose of this study was to determine, on the basis of published reports, whether aspirin use during the first trimester of pregnancy is associated with an increased risk of congenital malformations. STUDY DESIGN: We reviewed the literature for published studies that reported exposure to aspirin during the first trimester of pregnancy and congenital malformations. Two reviewers independently determined whether a study should be included in the final analysis and extracted the data. We calculated the pooled odds ratio and 95% CI. RESULTS: Twenty-two studies met the inclusion criteria. In the eight studies that reported an overall risk, the risk of congenital malformations in offspring of women who were exposed to aspirin was not significantly higher than that in control subjects (odds ratio, 1.33; 95% CI, 0.94-1.89). However, a significantly increased risk of gastroschisis (odds ratio, 2.37; 95% CI, 1.44-3.88) was found. CONCLUSION: We found no evidence of an overall increase in the risk of congenital malformations that could be associated with aspirin. Aspirin exposure during the first trimester may be associated with an increased risk of gastroschisis. 相似文献

Long-term outcome and alloantibody production in a non-myeloablative regimen for induction of renal allograft tolerance 总被引:9,自引:0,他引:9
Kawai T Poncelet A Sachs DH Mauiyyedi S Boskovic S Wee SL Ko DS Bartholomew A Kimikawa M Hong HZ Abrahamian G Colvin RB Cosimi AB 《Transplantation》1999,68(11):1767-1775
BACKGROUND: Multilineage chimerism and long-term acceptance of renal allografts has been produced in non-human primates conditioned with a nonmyeloablative regimen. Our study was undertaken to evaluate the immunological and pathological status of long-term survivors and to define the role of splenectomy and of the primarily vascularized kidney in the regimen. METHOD: Monkeys were treated with the basic regimen, including: total body irradiation, thymic irradiation, antithymocyte globulin, donor bone marrow transplantation, and a 4-week course of cyclosporine after which no further immunosuppression was given. They were divided into four groups according to the timing of kidney transplantation (KTx) and splenectomy as follows; group A (n=13): KTx and splenectomy on the day of donor bone marrow transplantation (day 0); group B (n=3): KTx on day 0 without splenectomy; group C (n=7): splenectomy on day 0 but delayed KTx until 3 to 16 weeks post-donor bone marrow transplantation; group D (n=3): both splenectomy and KTx delayed until day 120 post-donor bone marrow transplantation. RESULTS: In group A, 11 of 13 monkeys developed chimerism and 9 monkeys achieved long-term survival of 4 to 70 months without evidence of chronic vascular rejection. Alloantibodies were detected in only one long-term survivor. In contrast, all three monkeys in group B developed alloantibodies and rejected their allografts. In group C, long-term survival without alloantibody production was observed in two of three monkeys that had developed chimerism. In group D, all three recipients were sensitized and rejected the kidney allografts rapidly after transplantation. CONCLUSIONS: 1) Production of anti-donor antibody was prevented in most recipients that developed mixed chimerism in the regimens with splenectomy at the time of donor bone marrow transplantation. 2) If splenectomy is not included in the initial conditioning regimen, induction of B cell tolerance is less likely and the result is late onset of alloantibody production and allograft rejection. 3) Immediate transplantation of the kidney at the time of recipient conditioning is not essential for induction of donor specific hyporesponsiveness by bone marrow transplantation. 相似文献
