Further, it highlights the novel application of immune checkpoint inhibitors in the treatment of advanced posttransplant malignancy, in particular when the allograft is removed and the tumor is possibly of donor origin.Primary nonfunction (PNF) in the early postoperative period following liver transplantation is fatal if not managed appropriately with early retransplantation. Severe early allograft dysfunction can mimic PNF. The identification of treatable causative factors such as sepsis, hepatic artery, or portal vein thrombosis is essential to distinguish it from PNF, and their early management may avoid the need for retransplantation. In this article, we describe a case of sepsis-induced severe liver dysfunction from a contaminated graft perfused with normothermic machine perfusion (NMP), which presented in a manner similar to PNF. The implications of graft contamination are poorly described. To our knowledge, this is the first report of bacterial contamination of a graft that underwent NMP and subsequently caused severe sepsis in the recipient. The conditions created with NMP may be optimal for certain micro-organisms to thrive. The role of the liver in the immune system is complex as it provides an essential barrier to enterically derived portal venous pathogens and produces numerous acute phase proteins that augment the systemic immune response. Additionally, the liver is also known to restrain harmful and excessive systemic immune responses such as those that occur with the sepsis syndrome.

No patient of the 129 included reported suspected symptoms; 3 isolated themselves in auto-quarantine for flu-like symptoms. All treated patients regularly continued their therapies; 8 missed one infusion 3 for self-isolation with 2 relatives, and 3 refused to receive nurse at home. All elective procedures were deferred and telemedicine was adopted.
F508del is prototypical of Class 2 CFTR mutations associated with protein misprocessing and reduced function. Corrector compounds like lumacaftor partially rescue the processing defect of F508del-CFTR whereas potentiators like ivacaftor, enhance its channel activity once trafficked to the cell surface. We asked if emerging modulators developed for F508del-CFTR can rescue Class 2 mutations previously shown to be poorly responsive to lumacaftor and ivacaftor.

Rescue of mutant CFTRs by the correctors AC1, AC2-1 or AC2-2 and the potentiator, AP2, was studied in HEK-293 cells and in primary human nasal epithelial (HNE) cultures, using a membrane potential assay and Ussing chamber, respectively.

In HEK-293 cells, we found that a particular combination of corrector molecules (AC1 plus AC2-1) and a potentiator (AP2) was effective in rescuing both the misprocessing and reduced function of M1101K and G85E respectively. These findings were recapitulated in patient-derived nasal cultures, although another corrector combination, AC1 plus AC2-2 also improved misprocessing in these primary tissues. Interestingly, while this corrector combination only led to a modest increase in the abundance of mature N1303K-CFTR it did enable its functional expression in the presence of the potentiator, AP2, in part, because the nominal corrector, AC2-2 also exhibits potentiator activity.

Strategic combinations of novel modulators can potentially rescue Class 2 mutants thought to be relatively unresponsive to lumacaftor and ivacaftor.

To determine the deception rate or concordance between the interview on smoking and cooximetry in COPD patients from a monographic consultation.

Prospective observational study to evaluate the concordance between the values of cooximetry and the response to a clinical interview on smoking.

COPD monographic consultation, Pneumology, Seville.

Patients with a confirmed diagnosis of COPD in any degree.

Clinical interview and measurement of carbon monoxide by cooximetry.

Cooximetry values, responses on smoking, sociodemographic variables.

n 169. 107 patients presented values less than or equal to 6 ppm compared to 62 with values greater than 6 ppm, determining a prevalence of active smoking of 36.7%. The deception rate was 19.5% of the total sample (24.3% of all those who claimed not to smoke), with a Cohen kappa of 0.48 and p < 0.000. 40% of patients confessed not having told the truth. No relationship of this data was found with age, accumulated tobacco consumption or FEV1. A significant relationship with sex was found (deception rate 31.8% in women vs. 15.2% in men, p 0.017).

In spite of our attempts to make patients stop smoking, a considerable deception rate was found in our consultation; higher among women, recent ex-smokers or in the process of abandonment, so it would be essential to incorporate objective measures such as the cooximeter in the approach of this type of patient.

To assess the effects of plerixafor on function and endothelial regeneration of endothelial progenitor cells (EPCs).

The proliferation and adhesion capacity of EPCs were evaluated in vitro. Furthermore, the expression levels of CXC chemokine receptor-7 (CXCR7) were detected before and after treatment with plerixafor. The CXCR7 expression of EPCs was knocked-down by RNA interference to evaluate the role of CXCR7 in regulating function of EPCs. A rat carotid artery injury model was established to assess the influences of plerixafor on endothelial regeneration.

Plerixafor stimulated adhesion capacity of EPCs, associating with upregulation of CXCR7 and activation of LFA-1 and VLA-4 molecules. Knockdown of CXCR7 slightly impaired proliferation capacity but significantly attenuated adhesion capacity of EPCs. Plerixafor facilitated endothelial repair at 7days, while reduced neointimal hyperplasia at 7 and 14days via recruiting more EPCs participating in endothelial reparation.

Plerixafor can positively regulate adhesion capacity of EPCs to HUVECs via elevating the expression level of CXCR7 and stimulating LFA-1 and VLA-4 molecules activation.
