The aim of this IRB-approved study was to analyze prospectively quality of life (QOL) and psychological changes in 30 ESRD patients before and after kidney transplantation (KT). Semi-structured interviews were conducted after inclusion on the waiting list (A). Follow-up interviews were performed 6 months later with patients still awaiting KT (B6, n= 15), and with transplant recipients 6, 12 and 24 months after KT (C6, n=15; C12, n=15; C24, n=14). Qualitative thematic analysis was performed. A: All patients reported loss of freedom, 87% tried to maintain normality; 57% modified medical directives. All mentioned emotional fragility, negative thoughts (43%), and suicidal thoughts (20%) related to loss of QOL from dialysis (D), and professional tension (26%). B6: 40% reported no change compared to baseline, while 60% mentioned increase of illness intrusiveness, 46% D side effects, 40% communication problems, and 33% concerns about the waiting list handling. Fear of emotional breakdown (40%), couple problems (47%), and worsened professional difficulties (20%) were reported. C6: All patients reported recovery of QOL and concerns about acute rejection. 73% were anxious about laboratory results. 93% felt dependent on immunosuppressants (IS), 47% reported difficulties coping with their regimen, and 47% were concerned about side effects; 67% had resumed work, but medical constraints led 40% to professional stigmatization. C12: All enjoyed good QOL. Adherence to IS was mandatory (100%). All were aware of the limited long-term graft survival and 47% anxious about a possible return to D. 60% underlined positive life value; 47% resumed a full time job; 40% were on social security. C24: Good QOL was underlined (86%). Patients stated they would prefer re-TX to resuming D (71%). Post-TX health problems were mentioned (64%); increase of creatinine levels induced fear (36%). 79% complained about side effects. 64% reported changes in life values. This study reveals positive QOL and psychological transformations after KT, which are associated with positive changes related to graft survival and freedom from D. Psychological follow-up should be offered to patients who face relapsing ESRD or post-TX co-morbidities.

Objectives : The FREEDOM trial1 open-label extension is designed to evaluate the long-term efficacy and safety of denosumab for up to 10 years. We report the results from the first 2 years of the extension, representing up to 5 years of denosumab exposure.Materials/Methods : Postmenopausal women enrolled in the extension previously completed FREEDOM. During the extension, all women receive denosumab (60 mg) every 6 months and calcium and vitamin D daily. For the FREEDOM denosumab group, the data reflect 5 years of denosumab treatment (long-term group). For the FREEDOM placebo group, the data reflect 2 years of denosumab treatment (de novo group). P-values are descriptive.Results : There were 4550 (70.2%) FREEDOM women enrolled in the extension (2343 long-term; 2207 de novo). During the 4th and 5th years of denosumab treatment, the long-term group had further 1.9% and 1.7% increases in lumbar spine BMD and further 0.7% and 0.6% increases in total hip BMD (all P<0.0001 compared with extension baseline). Total BMD increases with 5-year denosumab treatment were 13.7% (lumbar spine) and 7.0% (total hip). In the de novo group, BMD increased during the first 2 years of denosumab treatment by 7.9% (lumbar spine) and 4.1% (total hip) (all P<0.0001 compared with extension baseline). After denosumab administration, serum CTX was rapidly and maximally reduced in both groups with the characteristic attenuation observed at the end of the dosing interval, as previously reported.2 Incidences of new vertebral and nonvertebral fractures were low and below rates observed in the FREEDOM placebo group. Adverse event reports were similar for both groups: in the long-term group, 83.4% reported AEs and 18.9% were serious. In the de novo group, the percentages were 82.8% and 19.4%, respectively. In FREEDOM, the respective percentages were 92.8% and 25.8% in the denosumab group and 93.1% and 25.1% in the placebo group. Two subjects in the de novo group had AEs adjudicated to ONJ which healed without further complications ; one resolved within the 6-month dosing interval and denosumab was continued. There were no atypical femoral fractures.Conclusions : Denosumab treatment for 5 years was well-tolerated and continued to significantly reduce CTX and significantly increase BMD.

Calcineurin is the only known serine-threonine phosphatase under calcium-calmodulin control and key regulator of the immune system. Treatment of patients with calcineurin-inhibitory drugs like cyclosporin A and FK506 to prevent graft rejection dramatically increases the risk of cutaneous squamous cell carcinoma, which is a major cause of death after organ transplants. Recent evidence indicates that suppression of calcineurin signaling, together with its impact on the immune system, exerts direct tumor-promoting effects in keratinocytes, enhancing cancer stem cell potential. The underlying mechanism involves interruption of a double negative regulatory axis, whereby calcineurin and nuclear factors of activated T-cell signaling inhibits expression of ATF3, a negative regulator of p53. The resulting suppression of keratinocyte cancer cell senescence is of likely clinical significance for the many patients under treatment with calcineurin inhibitors and may be of relevance for other cancer types in which altered calcium-calcineurin signaling plays a role.

1. As trees in a given cohort progress through ontogeny, many individuals die. This risk of mortality is unevenly distributed across species because of many processes such as habitat filtering, interspecific competition and negative density dependence. Here, we predict and test the patterns that such ecological processes should inscribe on both species and phylogenetic diversity as plants recruit from saplings to the canopy. 2. We compared species and phylogenetic diversity of sapling and tree communities at two sites in French Guiana. We surveyed 2084 adult trees in four 1-ha tree plots and 943 saplings in sixteen 16-m2 subplots nested within the tree plots. Species diversity was measured using Fisher's alpha (species richness) and Simpson's index (species evenness). Phylogenetic diversity was measured using Faith's phylogenetic diversity (phylogenetic richness) and Rao's quadratic entropy index (phylogenetic evenness). The phylogenetic diversity indices were inferred using four phylogenetic hypotheses: two based on rbcLa plastid DNA sequences obtained from the inventoried individuals with different branch lengths, a global phylogeny available from the Angiosperm Phylogeny Group, and a combination of both. 3. Taxonomic identification of the saplings was performed by combining morphological and DNA barcoding techniques using three plant DNA barcodes (psbA-trnH, rpoC1 and rbcLa). DNA barcoding enabled us to increase species assignment and to assign unidentified saplings to molecular operational taxonomic units. 4. Species richness was similar between saplings and trees, but in about half of our comparisons, species evenness was higher in trees than in saplings. This suggests that negative density dependence plays an important role during the sapling-to-tree transition. 5. Phylogenetic richness increased between saplings and trees in about half of the comparisons. Phylogenetic evenness increased significantly between saplings and trees in a few cases (4 out of 16) and only with the most resolved phylogeny. These results suggest that negative density dependence operates largely independently of the phylogenetic structure of communities. 6. Synthesis. By contrasting species richness and evenness across size classes, we suggest that negative density dependence drives shifts in composition during the sapling-to-tree transition. In addition, we found little evidence for a change in phylogenetic diversity across age classes, suggesting that the observed patterns are not phylogenetically constrained.

PURPOSE: Epithelial cell adhesion molecule (Ep-CAM) recently received increased attention not only as a prognostic factor in breast cancer but also as a potential target for immunotherapy. We examined Ep-CAM expression in 402 consecutive node-negative breast cancer patients with long-term follow-up not treated in the adjuvant setting. EXPERIMENTAL DESIGN: Ep-CAM expression was evaluated by immunostaining. Its prognostic effect was estimated relative to overexpression/amplification of HER-2, histologic grade, tumor size, age, and hormone receptor expression. RESULTS: Ep-CAM status was positive in 106 (26.4%) patients. In multivariate analysis, Ep-CAM status was associated with disease-free survival independent of age, pT stage, histologic grade, estrogen receptor (ER), progesterone receptor (PR), as well as HER2 status (P = 0.028; hazard ratio, 1.60; 95% confidence interval, 1.05-2.44). Recently, so-called triple-negative (HER-2, ER, and PR) breast cancer has received increased attention. We noticed a similar association of Ep-CAM with disease-free survival in the triple-negative group as for the entire cohort. CONCLUSION: In this study of untreated breast cancer patients, Ep-CAM overexpression was associated with poor survival in the entire cohort and in the subgroup of triple-negative breast cancer. This suggests that Ep-CAM may be a well-suited target for specific therapies particularly in HER-2-, ER-, and PR-negative tumors.

The finding of an eosinophilic aseptic meningitis in IV drug abuse is usually suggestive of an opportunistic infection or an allergic reaction. However, HIV-negative patients are at lower risk for developing these complications. Two young HIV-negative patients, with previous intravenous polytoxicomany, developed cystic arachnoiditis over the spinal cord associated with eosinophilic meningitis. Histology of the meningeal spinal cord lesions revealed a vasculocentric mixed inflammatory reaction. In one patient prednisone led to marked clinical improvement. Since infection, vasculitis, sarcoidosis and previous myelography were ruled out, we believe that the syndrome of eosinophilic aseptic arachnoiditis may be related to an hyperergic reaction in the meniges toward drug-adulterants inoculated through the intravenous route.

The aim of this IRB-approved study was to prospectively analyze psychological transformations in ESRD patients before and after transplantation (KT). Semi-structured interviews were conducted in 30 patients (mean age = 53±10) after their inclusion on the waiting-list (Gr. A). Follow-up interviews were performed 6 months later in 15 patients still awaiting KT (Gr. B6), and in 15 patients 6 months (Gr. C6) and 12 months (Gr. C12) after KT. Qualitative analysis was performed. Gr: A:All patients underlined loss of freedom, 87% devoted much energy to maintain normality, 57% modified medical directives. All reported emotional fragility related to dialysis and loss of quality of life (QOL), negative (43%) or suicidal thoughts (20%). Professional stigma was underlined (26%). Gr: B6:40% reported no change, 60% mentioned increase of illness intrusiveness, 46% dialysis side-effects, 40% communication problems, 33% tension with medical staff and waiting list handling. Fear of emotional breakdown (40%), couple problems (47%) and worsened professional difficulties (20%) were reported. Gr: C6:All patients mentioned improved QOL and freedom recovery (87%). All expressed concerns about possible acute rejection, 73% were anxious about laboratory results, 93% experienced dependence to immunosuppressants, 47% reported difficulties in handling medication, 21% feared to forget them, 47% were concerned about side-effects, 67% had resumed work but medical constraints led to professional tension (40%). Gr: C12:All mentioned recovered QOL. Medical controls were accepted as a routine (87%) and adherence to medication was mandatory (100%). All mentioned the limited long-term graft survival and 47% were anxious about possible return to dialysis, especially younger patients (27%). Positive identity and existential changes were reported (60%). This prospective qualitative study identifies psychological modifications in the course of KT. It provides a basis to adequately address concerns, but it shows also that KT is clearly associated with positive psychological transformations.

BACKGROUND: Up to 10% of the patients in whom suspected betalactam hypersensitivity (HS) has been excluded by skin and challenge tests report suspected allergic reactions during subsequent treatments with the same or very similar betalactams. It has been suggested that the reactions may result from a resensitization induced by the challenge performed at the time of the allergological work-up. However, most patients did not undergo a second allergological work-up, to determine if the reactions resulted from betalactam HS or not. OBJECTIVES: We aimed to determine if children diagnosed nonallergic to betalactams have tolerated subsequent treatments with the initially suspected and/or other betalactams, and, in case of a reaction, if the reaction resulted from betalactam HS. Methods: We sent a questionnaire concerning the clinical history of their children to the parents of 256 children previously diagnosed nonallergic to betalactams. A second allergological work-up was performed in the children reporting suspected allergic reactions during subsequent treatments with the same and/or other betalactams. Skin tests were performed with the soluble form of the suspected (or very similar) betalactams and other betalactams from the same and other classes. Skin test responses were assessed at 15-20 min (immediate), 6-8 h (semi-late) and 48-72 h (late). Oral challenge (OC) was performed in children with negative skin tests, either at the hospital (immediate and accelerated reactions), or at home (delayed reactions). RESULTS: A response was obtained from 141 children (55.3%). Forty-eight (34%) of those children had not been treated with the betalactams for whom a diagnosis of allergy had been ruled out previously. Seven (7.5%) of the 93 children who had been treated again reported suspected allergic reactions. Skin tests and OC were performed in six of those children, and gave negative results in five children. In one child previously diagnosed nonallergic to amoxicillin associated with clavulanic acid, we diagnosed a delayed HS to clavulanic acid and a serum sickness-like disease to cefaclor. Thus, the frequency of reactions resulting from betalactam HS in children with negative skin and challenge tests is very low, and does not exceed 2.1% (2/93) if we consider that the child which refused a second allergological work-up is really allergic to betalactams. CONCLUSION: Our results in a very large number of children show that reactions presumed to result from betalactam HS are rare in children in whom the diagnosis of betalactam allergy has been ruled out previously. Moreover, they suggest that, as shown for the initial reactions, most of the reactions during subsequent treatments are rather a consequence of the infectious diseases for whom betalactams have been prescribed than a result of betalactam HS. Finally, they suggest that the risk of resensitization by OC is very low, and do not support the notion that skin testing should be repeated in children diagnosed nonallergic to betalactams.

This paper reconsiders the empirical evidence on the asymmetricoutput effects of monetary policy. Asymmetric effects is a common feature ofmany theoretical models, and there are many different versions of suchasymmetries. We concentrate on the distinctions between positive andnegative money-supply changes, big and small changes in money-supply, andpossible combinations of the two asymmetries. Earlier research has foundempirical evidence in favor of the former of these in US data. Using M1 asthe monetary variable we find evidence in favor of neutrality of big shocksand non-neutrality of small shocks. The results may, however, be affected bystructual instability of M1 demand. Thus, we substitute M1 with the federalfunds rate. In these data we find that only small negative shocks affectreal aggregate activity. The results are interpreted in terms of menu-costmodels.

Experiments in which subjects play simultaneously several finite prisoner's dilemma supergames with and without an outside optionreveal that: (i) subjects use probabilistic start and endeffect behaviour, (ii) the freedom to choose whether to play the prisoner's dilemma game enhances cooperation, (iii) if the payoff for simultaneous defection is negative, subjects' tendency to avoid losses leads them to cooperate; while this tendency makes them stick to mutual defection if its payoff is positive.
