Donation‐after‐Determination‐of‐Cardiac‐Death (DDCD) donor lungs can potentially increase the pool of lungs available for Lung Transplantation (LTx). This paper presents the 5‐year results for Maastricht category III DDCD LTx undertaken by the multicenter Australian National DDCD LTx Collaborative. The Collaborative was developed to facilitate interaction with the Australian Organ Donation Authority, standardization of definitions, guidelines, education and audit processes. Between 2006 and 2011 there were 174 actual DDCD category III donors (with an additional 37 potentially suitable donors who did not arrest in the mandated 90 min postwithdrawal window), of whom 71 donated lungs for 70 bilateral LTx and two single LTx. In 2010 this equated to an “extra” 28% of donors utilized for LTx. Withdrawal to pulmonary arterial flush was a mean of 35.2 ± 4.0 min (range 18–89). At 24 h, the incidence of grade 3 primary graft dysfunction was 8.5%[median PaO2/FiO2 ratio 315 (range 50–507)]. Overall the incidence of grade 3 chronic rejections was 5%. One‐ and 5‐year actuarial survival was 97% and 90%, versus 90% and 61%, respectively, for 503 contemporaneous brain‐dead donor lung transplants. Category III DDCD LTx therefore provides a significant, practical, additional quality source of transplantable lungs. 相似文献

An antiviral containment strategy for foot‐and‐mouth disease (FMD) outbreaks could support or replace current contingency plans in case of an outbreak in Europe and could spare many healthy animals from being pre‐emptively culled. Recently, substantial progress has been made towards the development of small molecule drugs that inhibit FMD virus (FMDV) replication in vitro. For the initial in vivo evaluation of antiviral lead molecules, a refined FMDV‐infection model in guinea pigs (GP) is herewith described. This GP model was validated by demonstrating the antiviral effect of T‐1105 (an influenza virus inhibitor with reported activity against FMDV). Sixteen animals were orally administered with T‐1105 twice daily (400 mg/kg/day) for five consecutive days and inoculated intraplantarly with 100 GPID50 of the GP‐adapted FMDV strain O1 Manisa 1 h after the first administration. The efficacy of T‐1105 was compared with that of prophylactic vaccination with a highly potent double‐oil emulsion‐inactivated O1 Manisa vaccine. Ten animals received a single, full (2 ml) cattle vaccine dose and were inoculated 3 weeks later. Fourteen T‐1105‐treated and all vaccinated GP were completely protected from generalization of vesicular lesions. At 2 dpi, viral RNA was detected in serum of 9/16 T‐1105‐treated and of 6/10 vaccinated animals. At 4 dpi, viral RNA was detected in serum, organs and oral swabs of half of the T‐1105‐treated animals and only in the serum of 1/10 of the vaccinated animals. Mean viral RNA levels in serum and organs of T‐1105‐treated and vaccinated animals were reduced compared to untreated controls (P < 0.01). T‐1105 conferred a substantial clinical and virological protection against infection with O1 Manisa, similar to the protection afforded by vaccination. These results validate the suitability of the enhanced GP model for the purpose of initial evaluation of inhibitors of FMDV replication and illustrate the potential of selective inhibitors of viral replication to control FMD outbreaks. 相似文献

Inducible expression of a prostate cancer-testis antigen, SSX-2, following treatment with a DNA methylation inhibitor 总被引:1,自引:0,他引:1
BACKGROUND: Active immunotherapies are one approach being developed as novel treatments for prostate cancer. Critical to the success of these therapies is the identification of appropriate target antigens. We have been seeking to identify immunologically recognized proteins, cancer-testis antigens (CTA) in particular, in patients with prostate cancer that would be rational target antigens. METHODS: Using a previously reported panel of 29 different CTA, we used sera from 98 patients with prostate cancer and 50 healthy male blood donor controls to detect CTA-specific IgG. We then further evaluated the expression of one antigen, SSX-2, in prostate cancer cell lines and tissues. RESULTS: We identified IgG specific for NY-ESO-1, LAGE-1, NFX-2, and SSX-2 in at least 1/98 individuals with prostate cancer. We demonstrated that SSX-2 is a prostate CTA, and its expression is associated with metastatic prostate cancer. In addition, we report that the treatment of at least two human prostate cancer cell lines with the DNA methylation inhibitor 5-aza-2'-deoxycytidine induced the expression of SSX-2. In contrast, treatment of a normal prostate epithelial cell line (RWPE-1) with 5-aza-2'-deoxycytidine did not induce SSX-2 expression. CONCLUSIONS: Our findings suggest that SSX-2 could be further pursued as an immunotherapeutic target in prostate cancer, and that treatment with 5-aza-2'-deoxycytidine could be exploited to modulate antigen expression in combination with immunotherapeutic approaches. 相似文献

This study examined the role of negative cognitions in emotional problems following relationship dissolution. Seventy‐nine undergraduate students who experienced a relationship break‐up completed measures of break‐up related complicated grief, depression and anxiety, together with an adjusted version of the Grief Cognitions Questionnaire (GCQ) that assesses four types of global negative beliefs, negative cognitions about self‐blame and the responses of others, and three types of negative interpretations of one's own grief reactions. Results showed that all cognitive variables tapped by the GCQ were significantly associated with complicated grief, and—except for global beliefs about life—with depression and anxiety. Most of these associations remained significant when controlling for the influence of initiator status, variables linked with the ended relationship (e.g. duration) and personality factors (e.g. attachment anxiety, neuroticism). Catastrophic misinterpretations about one's own reactions, global negative beliefs about the self and cognitions reflecting self‐blame were the strongest cognitive correlates of break‐up related emotional problems. Overall, the findings are in keeping with cognitive models of trauma and loss, and suggest that changing negative cognitions could be a useful intervention for those who fail to recover from a relationship break‐up.

Ceramic‐on‐ceramic and metal‐on‐metal bearing surfaces are often employed for total hip replacement because of their resistance to wear. However, they have some limits: brittleness is a major concern for ceramic, and ion release is a drawback for metal. To reduce the effect of these limitations, a hybrid coupling of ceramic‐on‐metal has been proposed. The theoretical advantage of this new coupling might lead orthopedic surgeons to use it indiscriminately. We asked whether the wear rate of this innovative solution was comparable with that of ceramic‐on‐ceramic, which is considered to be the gold standard for wear resistance. In a hip simulator study, we tested the wear pattern of a hybrid ceramic‐on‐metal coupling supplied by the same distributor; in particular, three different configurations were tested for 5 million cycles: 36‐mm ceramic‐on‐ceramic, 32‐mm and 36‐mm ceramic‐on‐metal. These combinations were gravimetrically and geometrically evaluated. After 5 million cycles, the volumetric loss for the metal acetabular cups (Φ 36‐mm) was 20‐fold greater than that of the ceramic cups of the same size (Φ 36‐mm); a volumetric loss of 4.35 mm3 and 0.26 mm3 was observed, respectively, for ceramic‐on‐metal and ceramic‐on‐ceramic combinations. Significant statistical differences were observed between all 36‐mm different combinations (P < 0.0001). The increased diameter of the 36‐mm ceramic‐on‐metal configuration resulted in a lower volumetric loss compared with that of the 32‐mm ceramic‐on‐metal configuration. Our findings showed an increase in wear for the proposed hybrid specimens with respect to that of the ceramic‐on‐ceramic ones. This confirms that even in the case of ceramic‐on‐metal bearings, mixing and matching could not prove effective wear behavior, not even comparable with that of the ceramic‐on‐ceramic gold standard. 相似文献

Cutaneous damage is one of the characterized manifestations in chronic graft‐versus‐host disease (cGVHD). When local effective immunity in the skin is altered to a dysimmune reaction, cutaneous injuries occur. Toll‐like receptor 4 signaling is regarded as a central mediator of inflammation and organ injury. In this study, we found that TLR4 mRNA in peripheral blood from patients with cutaneous cGVHD was markedly increased compared with that from non‐GVHD patients and healthy controls. In addition, NF‐κB expression, TLR4 downstream signaling, and TLR4‐mediated cytokines, including IL‐6 and ICAM‐1, were upregulated. Moreover, ICAM‐1 was widely distributed in skin biopsies from patients with cutaneous cGVHD. We also found that LPS induced TLR4‐mediated NF‐κB activation and IL‐6 and ICAM‐1 secretion in human fibroblasts in vitro. Thus, TLR4, NF‐κB, IL‐6, and ICAM‐1 contribute to the inflammatory response that occurs in cutaneous cGVHD, indicating the TLR4 pathway may be a novel target for cutaneous cGVHD therapy. 相似文献

Aim The aim of this study was to evaluate systematically the efficacy and safety of oral uracil‐tegafur (UFT) plus leucovorin (LV) compared with infusional fluorouracil (5‐FU) plus LV for advanced colorectal cancer. Method Eligible studies were identified from Medline, Embase and the Cochrane Library. The end‐points included overall survival and overall tumour response rate, and toxicity including leucopenia, febrile neutropenia, stomatitis/mucositis and diarrhoea. Results Five randomized controlled trials were identified. Pooled data demonstrated no difference in overall survival between the oral UFT plus LV regimen and the 5‐FU bolus plus LV regimen [hazard ratio 1.013; 95% confidence interval (CI) 0.911–1.127].The fixed‐effect pooled estimate for overall tumour response rate showed no significant difference between the two regimens (relative risk 0.893; 0.672–1.187). Grade 3–4 leucopenia [odds ratio (OR) 0.126; 955 CI 0.048–0.326], grade 1–4 leucopenia (OR 0.089; 95% CI 0.067–0.119) and grade1–4 febrile neutropenia (OR 0.020; 95% CI 0.004–0.102) were significantly less prominent in the oral UFT regimens. For nonhaematological toxicities, grade 3–4 stomatitis/mucositis (OR 0.075; 95% CI 0.039–0.146), grade 3–4 infection (OR 0.484; 95% CI 0.310–0.758), grade 1–4 infection (OR 0.672; 95% CI 0.547–0.826, P < 0.001), grade 1–4 diarrhoea (OR 0.743; 95% CI 0.626–0.881) were also less likely to happen in patients in the oral UFT plus LV regimen, while there was no significant difference between the two treatment regimens with respect to grade 1–4 stomatitis/mucositis (OR 0.278; 95% CI 0.053–1.456) and grade 3–4 (OR 1.174; 95% CI 0.983–1.403) diarrhoea. Conclusion Oral UFT or 5‐FU bolus combined with LV results in similar overall survival and tumour response rates for advanced colorectal cancer. The former treatment regimen is greatly superior in terms of toxicity, especially haematological toxicity. 相似文献

Foot‐and‐Mouth Disease (FMD) is a clinical syndrome in animals due to FMD virus that exists in seven serotypes, whereby recovery from one sero‐type does not confer immunity against the other six. So when considering intervention strategies in endemic settings, it is important to take account of the characteristics of the different serotypes in different ecological systems. FMD serotypes are not uniformly distributed in the regions of the world where the disease still occurs. For example, the cumulative incidence of FMD serotypes show that six of the seven serotypes of FMD (O, A, C, SAT‐1, SAT‐2, SAT‐3) have occurred in Africa, while Asia contends with four sero‐types (O, A, C, Asia‐1), and South America with only three (O, A, C). Periodically there have been incursions of Types SAT‐1 and SAT‐2 from Africa into the Middle East. This paper describes the global dynamics for the seven sero‐types and attempts to define FMD epidemiological clusters in the different regions of the world. These have been described on a continent by continent basis. The review has reaffirmed that the movement of infected animals is the most important factor in the spread of FMD within the endemically infected regions. It also shows that the eco‐system based approach for defining the epidemiological patterns of FMD in endemic, which was originally described in South America, can apply readily to other parts of the world. It is proposed that any coordinated regional or global strategy for FMD control should be based on a sound epidemiological assessment of the incidence and distribution of FMD, identifying risk sources as either primary or secondary endemic eco‐systems. 相似文献

A systematic vaccination programme is ongoing in India to control the three prevailing serotypes (A, O, Asia1) of foot‐and‐mouth disease (FMD) virus. Under the programme, more than 120 million bovine (term bovine applicable to both cattle and buffalo in this study) population of 221 of the 666 districts in the country are being bi‐annually vaccinated with trivalent vaccine since 2010. Although clinical disease has reduced in these districts because of the systematic vaccinations, an abrupt increase in the number of FMD cases was recorded in 2013. Hence, a longitudinal field study was conducted in the year 2014 to estimate the serological herd immunity level in bovines, the impact of systematic vaccinations and field efficacy of the vaccines used. Serum samples (n = 115 963) collected from 295 districts of the 18 states of the country were analysed to estimate antibody titres against structural proteins of the three serotypes. The efficacy of the vaccine was demonstrated in the control group (group‐D) where animals of the group were identified by ear tags for the purpose of repeated sampling after vaccination. Progressive building of the herd immunity in the field after systematic vaccination was demonstrated. The mean antibody titre against the serotypes O, A and Asia1 was estimated as log10 1.93 (95% CI 1.92–1.93), 2.02 (2.02–2.02) and 2.02 (2.02–2.02), respectively, in the states covered under the control programme. However, in other states herd immunity was significantly low [mean titre log10 1.68 (95% CI 1.67–1.69), 1.77 (1.76–1.78) and 1.85 (1.84–1.86) against the three serotypes]. Inverse relationship between the herd immunity and FMD incidences was observed the states following different vaccination practices. The study helped in demarcation of FMD risk zones in the country with low herd immunity. Estimation of herd immunity kinetics in the field helped in refining the vaccination schedule under the control programme. 相似文献

BACKGROUND: Few studies have used multiple assays to examine the functionality of mutant p53 in prostate cancer (CaP). We employed seven functional assays to study 16 representative mutant p53 alleles, six from localized and ten from metastatic CaP. METHODS: Yeast assays were employed to determine loss of function (LOF), partial function (PF), and dominant-negative status. Assays using p53-null Saos2 cells were used to determine whether mammalian cells transfected with mutant p53 could up-regulate the MDR-1 or PCNA promoters, alter IL-6 expression or confer the ability to grow in soft agar. As a further test of gain of function (GOF), p53-null PC3 cells stably transfected with these mutant p53 alleles were examined for cell cycle distributions. RESULTS: All 16 mutant p53 alleles demonstrated either total or partial LOF. All but one allele also had at least one gain of function; however, the pattern of GOF was different for each mutant allele. Alleles derived from both localized and metastatic CaP had similar GOF characteristics; however, only alleles from metastatic disease had significantly increased S-phase fractions. CONCLUSIONS: Different mutant p53 alleles from CaP had different, complex functional profiles. The lack of predictable patterns for these alleles suggest that each mutation may uniquely affect p53 function. 相似文献

The purpose of this study was to evaluate the effects and outcome of continuous‐flow left ventricular assist device (cf‐LVAD) therapy in patients with preoperative acute hepatic failure. The study design was a retrospective review of prospectively collected data. Included were 42 patients who underwent cf‐LVAD implantation (64.3% HeartMate II, 35.7% HeartWare) between July 2007 and May 2013 with preoperative hepatic failure defined as elevation of greater than or equal to two liver function parameters above twice the upper normal range. Mean patient age was 35 ± 12.5 years, comprising 23.8% females. Dilated cardiomyopathy was present in 92.9% of patients (left ventricular ejection fraction 17.3 ± 5.9%). Mean support duration was 511 ± 512 days (range: 2–1996 days). Mean preoperative laboratory parameters for blood urea nitrogen, serum creatinine, total bilirubin, and alanine aminotransferase were 9.5 ± 5.4 mg/dL, 110.3 ± 42.8 μmol/L, 51.7 ± 38.3 mmol/L, and 242.1 ± 268.6 U/L, respectively. All parameters decreased significantly 1 month postoperatively. The mean preoperative modified Model for Endstage Liver Disease excluding international normalized ratio score was 16.03 ± 5.57, which improved significantly after cf‐LVAD implantation to 10.62 ± 5.66 (P < 0.001) at 7 days and 5.83 ± 4.98 (P < 0.001) at 30 days postoperatively. One‐year and 5‐year survival was 75.9 and 48.1%, respectively. 21.4% of the patients underwent LVAD explantation for myocardial recovery, 16.7% were successfully transplanted, and 7.1% underwent LVAD exchange for device failure over the follow‐up period. Patients with preexisting acute hepatic failure are reasonable candidates for cf‐LVAD implantation, with excellent rates of recovery and survival, suggesting that cf‐LVAD therapy should not be denied to patients merely on grounds of “preoperative elevated liver enzymes/hepatopathy.” 相似文献

In this study, we evaluated the feasibility of our graft-versus-host disease (GVHD) prophylaxis with tacrolimus, methotrexate, and prednisolone in non-T-cell-depleted haploidentical hematopoietic stem cell transplantation (HSCT) for children. Twenty-one consecutive patients including those with hematological malignancies (n = 11), solid tumors (n = 7), and non-malignancies (n = 3) were analyzed. Myeloablative and reduced intensity conditionings were carried out in 5 and 16 patients, respectively, and both of the regimens contained anti-human T-lymphocyte immunoglobulin. Twenty (95%) of the 21 patients achieved primary engraftment. Acute GVHD of grades II-IV and III-IV were observed in nine (47%) and one (5%) patient, respectively, all of which were controllable by steroids. Chronic GVHD was observed in eight (51%) of the 17 evaluable patients, and one of them developed steroid refractory chronic GVHD. Treatment-related mortality occurred in three patients (15%), as a result of acute pancreatitis, chronic GVHD, and EB virus associated lymphoproliferative disease. The median follow-up of the 13 survivors was 24 months, and the two-yr probability of overall survival was 68%. The Karnofsky performance scale score of the 13 survivors was 100%. These results indicated the feasibility of our GVHD prophylaxis in non-T-cell-depleted haploidentical HSCT for children. 相似文献

Data from the US National Study of the Changing Workforce (a nationally representative sample of working adults) were used to test the hypothesis that employees with time‐flexible work policies reported less stress, higher levels of commitment to their employer, and reduced costs to the organization because of fewer absences, fewer days late, and fewer missed deadlines. The model provides persuasive findings for the hypothesized relationship and offers important suggestions to employers who can translate reduced illness into savings and increased commitment into better employees. Contrary to expectations, there were no gender differences in how employees responded to flexible work policies, showing that gender‐neutral work policies make financial sense. By showing that time‐flexible work policies provide employer benefits, we can hasten the change to a new worker model—one that is family and employer friendly. The business case for family‐friendly work policies may prove to be the best tool we have in changing how we live and work. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献

Formation of interleukin-6 (IL-6) in osteoblasts and bone marrow stromal cells is believed to regulate osteoclast recruitment. The anti-inflammatory cytokines interleukin-4 and -13 (IL-4 and IL-13) stimulate IL-6 production in human osteoblasts. We investigated the relative potencies, and synergistic effects, between IL-4, IL-13 and interleukin-1 (IL-1) on IL-6 formation in human osteoblast-like cells. Isolated human osteoblast-like cells were incubated for 72 h in the presence of various concentrations of IL-4, IL-13 and IL-1, and IL-6 secretion was measured by ELISA. All cytokines stimulated the secretion of IL-6. The rank order of potency was IL-1>IL-4>IL-13. There were no additive or synergistic effects between IL-4 and IL-13. However, co-stimulation with IL-1 and IL-4 resulted in a marked synergistic effect on IL-6 secretion. Co- stimulation with IL-1 and IL-13 gave a minor synergistic effect. In conclusion, IL-4/13 synergistically potentiates IL-1 induced secretion of IL-6 in human osteoblast-like cells. 相似文献

BACKGROUND: Prostate cancer is the most common cancer of men in the Western world. Despite the over-expression of tumor-associated antigens, like PSA or PSMA, immune activation is inefficient. The goal of this investigation was to assess in situ characteristics of prostate cancer-infiltrating lymphocytes and to determine their activation status and effector function. METHODS: We compared 17 carcinoma containing tissues, four benign prostatic hyperplasia tissues and eight healthy prostate tissues regarding lymphocyte subset composition, locoregional distribution, and functional status using immunohistological staining of cryopreserved tissues. For determination of lymphocyte subsets, serial sections were stained with CD3, CD4, and CD8 antibodies. Activation status and effector function were studied using CD69, interferon-gamma (IFN gamma), perforin, and CD3 zeta chain antibodies. T-cell-receptor repertoire (TCR) analysis was made to determine the complexity of infiltrating lymphocytes. RESULTS: CD3+, CD4+, and CD69+ T lymphocytes were prominent in tissues derived from patients with prostate carcinoma. CD8+ lymphocytes were significantly less than CD4+ lymphocytes. IFN gamma and perforin were downregulated on infiltrating lymphocytes compared to cells of healthy prostate tissue. Very few lymphocytes were detected within cancerous lesions whereas surrounding tissues showed extensive lymphocyte cluster formation. The TCR repertoire of infiltrating lymphocytes was broad and similar to that of healthy prostate tissue, giving no evidence for specific lymphocyte recruitment. CONCLUSIONS: In the prostate cancer microenvironment, CD4+ T lymphocytes dominated while CD8+ T cells were sparse. The lymphocytes exhibited signs of disturbed effector function. Consequently, the immune response against autologous tumor cells is likely to be inefficient in controlling tumor growth. 相似文献
