BACKGROUND: Transplantation for patients with a high pulmonary vascular resistance (PVR) carries an increased risk of mortality and right heart failure following heart transplantation and continues to be a major problem. We evaluated the use of hearts from patients who underwent heart and lung transplantation for primary pulmonary hypertension (PPH) as part of a domino procedure because these hearts have hypertrophied right ventricles used to increased pulmonary pressures, but could have a compromised left ventricle or irreversible damage of the right ventricle. METHODS: We reviewed 12 patients with PVR >4 Wood units who underwent orthotopic heart transplantation between 1989 and 1998 using hearts from donors with PPH as part of a domino procedure. RESULTS: We studied 10 men and 2 women, mean age 42.9 years. Mean PVR was 5.3 (range, 4-9) Wood units. Mean ischemia time was 85.3 minutes, and mean donor age was 32 years. Actuarial survival was 75% at 1 year and 75% at 5 years. In the early post-operative period, 3 patients had temporary arrhythmias, 2 required permanent pacemaker implantation, 1 had atrial fibrillation, and 1 had ventricular tachycardia that required defibrillator implantation. At a mean follow-up of 7.8 years, 2 patients had developed asymptomatic transplant coronary disease (both at 8.5 years after transplantation), 1 moderate and 1 very mild; the rest had none. Mean left ventricular ejection fraction at latest follow-up was 70.1% (range, 63%-78%). Right ventricular function assessed clinically and by echocardiography was adequate in the short and long term. CONCLUSIONS: Our results suggest that heart and lung recipients with PPH can provide useful donor hearts to patients with increased PVR and that these hearts function well in the intermediate and long term. 相似文献

用BA-ELISA斑点法检测痢疾杆菌免疫小鼠GALT中的特异性抗体分泌细胞(ASC) 总被引:1,自引:0,他引:1
改进的BA-ELISPOT法使免疫酶斑更为清晰,保存时间延长。用此法检测了痢疾杆菌福氏2a经口及腹腔免疫后,小鼠派伊尔氏(PP)淋巴结、肠系膜淋巴结(MLN)及脾脏(SPL)中特异性IgA、IgG、IgM抗体分泌细胞(AntibodySecretingcell,ASC)的动态变化,得到有规律的结果:两种免疫途径均能在PP及MLN中诱导出3类特异ASC的显著升高,但口服导致的升高其持续时间较腹腔途径为短。此外,腹腔途径还能诱导SPL中3种ASC升高。 相似文献

Relief of cough and nasal symptoms associated with allergic rhinitis by mometasone furoate nasal spray. 总被引:7,自引:0,他引:7

BACKGROUND: Cough commonly occurs as a symptom of seasonal allergic rhinitis (SAR), an inflammatory condition of the nasal mucous membranes that results in rhinorrhea, nasal stuffiness/congestion, nasal itching, and sneezing. Mometasone furoate nasal spray (MFNS, Nasonex, Schering, Kenilworth, NJ), an anti-inflammatory nasal corticosteroid, has been shown to be safe and effective in reducing the nasal inflammation of SAR. OBJECTIVE: To examine the effectiveness of MFNS in relieving SAR-associated cough, in addition to nasal symptoms. METHODS: This was a multicenter, randomized, double-blind study. Patients 12 years of age or older with > or = 1-year history of SAR symptoms, positive skin test to a prevailing seasonal allergen, moderate nasal symptoms, and moderate cough were treated for 14 days with MFNS 200 microg daily (n = 122) or placebo (n = 123). RESULTS: The group treated with MFNS showed significant improvement in the daytime cough severity score at endpoint compared with placebo (P = 0.049). Improvement in the nighttime cough severity score showed a trend in favor of MFNS treatment. Treatment with MFNS significantly improved total nasal symptoms in both the daytime and nighttime compared with placebo at endpoint (P < or = 0.017). Overall daytime symptom scores (cough + total nasal) improved significantly compared with placebo at endpoint (P = 0.005). Overall nighttime symptom scores improved significantly compared with placebo at endpoint (P = 0.028). Treatments were well tolerated, with no significant differences in the incidence of adverse events. CONCLUSIONS: MFNS is effective and well tolerated in the treatment of daytime cough associated with SAR. 相似文献

The UK government had intended to introduce a comprehensive Electronic Health Record (EHR) system in England by 2020. These EHRs would run across primary, secondary, and social care, linking data in a single digital platform. The objectives of this systematic review were to identify studies that compare EHR in terms of direct comparison between systems and to evaluate them using System and Software Quality Requirements and Evaluation (SQuaRE) ISO/IEC 25010. A systematic review was performed by searching Embase and Ovid MEDLINE databases between 1974 and April 2021. All original studies that appraised EHR systems and their providers were included. The main outcome measures were EHR system comparison and the eight characteristics of SQuaRE: functional suitability, performance efficiency, compatibility, usability, reliability, security, maintainability, and portability. A total of 724 studies were identified using the search criteria. After a review of titles and abstracts, this was filtered down to 40 studies as per the exclusion and inclusion criteria set out in our study. Seven studies compared more than one EHR. The following number of studies looked at the various aspects of the SQuaRE, respectively − 19 studies: functional suitability, performance efficiency: 18 studies, compatibility: 12 studies, usability: 25 studies, reliability: 6 studies, security: 2 studies, maintainability: 16 studies, portability: 13 studies. Epic was the most studied EHR system and one of the most implemented systems in the US market and one of the top ten in the UK. It is difficult to assess which is the most advantageous EHR system when they are assessed by SQuaRE''s 8 characteristics for software evaluation. 相似文献

The increasing availability of biosimilar medicines in Middle Eastern regions may provide an opportunity to increase the number of rheumatology patients who have access to traditionally more expensive biologic medicines. However, as well as a lack of real-world data on the use of biosimilar medicines in practice, the availability of intended copies in the region may undermine physician confidence in prescribing legitimate biosimilar medicines. There is a need for regional recommendations for healthcare professionals to ensure that biosimilar drugs can be used safely. Therefore, a literature search was performed with the aim of providing important recommendations for the regulation and use of biosimilar medicines in the Middle East from key opinion leaders in rheumatology from the region. These recommendations focus on improving the availability of relevant real-world data, ensuring that physicians are aware of the difference between intended copies and true biosimilars and ensuring that physicians are responsible for making any prescribing and switching decisions. 相似文献
