Background
Oligoryzomys longicaudatus (colilargo) is the rodent responsible for hantavirus pulmonary syndrome (HPS) in Argentine Patagonia. In past decades (1967–1998), trends of precipitation reduction and surface air temperature increase have been observed in western Patagonia. We explore how the potential distribution of the hantavirus reservoir would change under different climate change scenarios based on the observed trends. 相似文献85.
BACKGROUND: Factors influencing alloimmunization to transfused red blood cells (RBCs) are not well understood. Utilizing a murine model, we have recently reported that RBC alloimmunization is enhanced by recipient treatment with viral‐like polyinosinic polycytidylic acid (poly(I:C)). To determine whether a different subtype of inflammation also enhances RBC alloimmunization, we investigated the effects of the bacterial endotoxin lipopolysaccharide (LPS) on alloimmunization. STUDY DESIGN AND METHODS: Mice were treated with poly(I:C) or LPS; in select experiments, the precursor frequency of naïve antigen‐specific CD4+ T cells was increased using T cells from T‐cell receptor transgenic mice. Recipients were transfused with leukoreduced RBCs expressing the membrane‐bound hen egg lysozyme (mHEL) antigen, and alloimmunization was measured by anti‐HEL immunoglobulin G responses using enzyme‐linked immunosorbent assay and flow cytometric cross‐match. Costimulatory molecule expression was examined on antigen‐presenting cells (APCs) by flow cytometry. RESULTS: Increased expression of costimulatory molecules on APCs was seen after treatment with either poly(I:C) and LPS. In contrast to the enhancement of RBC alloimmunization observed after treatment with poly(I:C), LPS not only failed to enhance but also actively suppressed alloimmunization, even in the presence of increased mHEL‐specific CD4+ T cells (p < 0.001 LPS vs. control). CONCLUSIONS: These data demonstrate that the regulation of RBC alloimmunization by inflammatory stimuli is complex, including enhancement by a viral‐like stimulus and suppression by a bacterial‐type stimulus. The mechanism(s) are unlikely to involve variation in the costimulatory molecules studied, because only subtle differences on APCs were observed after treatment with poly(I:C) and LPS. 相似文献

Unique issues in blood donation and blood transfusion regarding African Americans (AA) in the United States span the donation process, manufacturing of products, and hospital transfusion service. As AAs become a growing population, a constant supply of blood donated by AAs is necessary to support this growth. Nationally, AAs are underrepresented in blood collection, which may be secondary to AAs having higher rates of anemia and other deferrable conditions or unique motivators as well as other barriers to blood donation. When investigating blood transfusion practices, blood utilization for different races and ethnicities is unknown. AAs may receive more red blood cell (RBC) transfusions because they have a higher proportion of diseases that require transfusion. Patients with sickle cell disease are at increased risk of RBC alloimmunization likely due to the predominance of RBC units from white donors in the existing blood supply, but it is not known if all AA recipients experience increased alloimmunization rates compared with whites. In conclusion, there is a need to increase donation by AAs, which can only be achieved by conducting studies to understand racial differences in donor recruitment and to better understand blood utilization and adverse events as a factor of race and ethnicity. 相似文献

Treatment options for a suspicious renal mass in a renal allograft include radical nephrectomy or nephron‐sparing surgery (NSS). To our knowledge robotic‐assisted laparoscopic partial nephrectomy (RPN) as treatment for a renal mass in a transplant kidney has not been previously reported. We report the case of RPN for a 7‐cm renal mass in a transplanted kidney. A 35‐year‐old female with reflux nephropathy received a living‐related donor kidney transplant in 1986. At 24 years after transplantation she had a 7‐cm Bosniak III cystic mass of the allograft detected on computerized tomography (CT) scan. Preoperative creatinine was 2.2 mg/dL with an estimated glomerular filtration rate (eGFR) of 25 mL/min/1.73 m2. RPN was performed with bulldog clamping of the renal vessels, the graft was left in situ and immunosuppression was maintained postoperatively. Tumor diameter was 7.3 cm with a nephrometry score of 10a. Warm ischemia time (WIT) was 26.5 min. Estimated blood loss was 100 mL. There was no change between pre‐ and postoperative eGFR. There were no operative complications. Histology was papillary renal cell carcinoma type 1, nuclear grade 2. Margins were negative. RPN is a technically feasible treatment option for a suspicious renal mass in renal allografts. 相似文献

The EuroQoL EQ-5D and MOS SF-36 are two generic quality of life measures that differ significantly in their design (the former being an index and the latter a profile). Both have been extensively used in evaluating interventions in acute disease. This study tested their comparative performance in a survey of patients with relapsing-remitting multiple sclerosis (MS).
METHODS: 309 patients with diagnosed relapsing-remitting MS were identified through the records of 5 specialist centers in North West England. Patients were contacted by telephone by a specialist MS nurse and asked to complete a set of questionnaires distributed by mail. The questionnaire booklet reproduced the English version of SF-36, together with the EQ-5D and a self completion form of the Barthel. Minimal additional background information was obtained from all respondents; 4 weeks following their completion of the initial booklet, a second identical booklet was sent to the first 200 initial respondents. Patients in this re-test sub-group were asked whether their health status had improved, deteriorated, or remained unchanged over the intervening period.
RESULTS: Of the 200 patients in the test/re-test subgroup, 144 (72%) replied on both occasions. Paired t-tests for the PCS, MCS, and general health perception scores on the SF-36 failed to generate comprehensive evidence of reliability. The weighted index form of the EQ-5D and the visual analogue scale self-ratings provided superior evidence of reliability. Standardized response means for both measures confirmed this general pattern.
CONCLUSION: EQ-5D performs satisfactorily as a generic measure of health-related quality of life in patients with MS. 相似文献
