001), and all of them had developed complex SAS at titration night requiring other modes of positive airway pressure therapy than the continuous mode (P = 0.004). Curve estimation models showed that the change from mixed apneas to central apneas was highly significant in patients developing complex SAS (r2 = 0.501; P = 0.022).

Our study showed that the summation of mixed apneas with the obstructive events conventionally underestimates the central components and the diagnosis of central SAS, which are fundamental in the risk stratification of complex SAS.

Recently, a large body of evidence suggested that the innate immune response and its soluble mediators may play a more important role during solid allograft rejection than originally thought. This review will highlight the role of novel soluble mediators that are involved in the activation of innate immunity during alloimmune response and solid allograft rejection. We will also discuss emerging strategies to alleviate the aforementioned events. Hence, novel, feasible and safe clinical therapies are needed in order to prevent allograft loss in solid organ transplantation. Fully understanding the role of soluble mediators of innate immune system activation may help to mitigate solid allograft rejection and improve transplanted recipients' outcomes.
Air pollution is associated with cardiopulmonary disease and death in the general population. Fine particulate matter (PM2.5) is particularly harmful due to its ability to penetrate into areas of gas exchange within the lungs. Persons with advanced lung disease are believed to be particularly susceptible to PM2.5 exposure but few studies have examined the effect of exposure on this population. Here we investigate the association between PM2.5 exposure and adverse waitlist events among lung transplant (LT) candidates.

US registry data were used to identify LT candidates listed between 1/1/2010-12/31/2016. Annual PM2.5 concentration at year of listing was estimated for each candidate's ZIP Code using NASA's SEDAC Global Annual PM2.5 Grids. We estimated crude and adjusted hazard ratios for adverse waitlist events, defined as death or removal, using Cox proportional hazards regression.

Of the 15,075 included candidates, median age at listing was 60, 43.8% were female and 81.7% were non-Hispanic white. Median ZIP Code PM2.5 concentration was 9.06µg/m3. When compared to those living in ZIP Codes with lower PM2.5 exposure (PM2.5 <10.53µg/m3), candidates in ZIP Codes in the highest quartile of PM2.5 exposure (≥10.53µg/m3) had 1.14-fold (95%CI 1.04-1.25) risk of adverse waitlist events. PF-8380 concentration The result remained significant after adjusting for demographics, education, insurance, smoking, lung allocation score, BMI, and blood type (HR=1.17; 95%CI 1.07-1.29).

Elevated ambient PM2.5 concentration was associated with adverse waitlist events among LT candidates. These findings highlight the impact of air pollution on clinical outcomes in this critically ill population.

Primary sclerosing cholangitis (PSC) is an indication for liver transplantation, but recurrence after liver transplantation is associated with poor outcomes often requiring repeat transplantation. We investigated whether autologous hematopoietic stem cell transplantation (aHSCT) could be used to stop progression of recurrent PSC and promote operational tolerance.

Twelve patients with recurrent PSC were fully evaluated and 5 were selected for aHSCT. Autologous hematopoietic stem cells were collected, purified by CD34 immunomagnetic selection and cryopreserved. Immunoablation using busulfan, cyclophosphamide and rabbit anti-thymocyte globulin was followed by aHSCT. The primary endpoint of the study was the establishment of operational tolerance defined as lack of biochemical, histologic and clinical evidence of rejection while off immunosuppression at 2 years post-aHSCT.

Two of the 5 patients achieved operational tolerance with no clinical or histological evidence of PSC progression or allo-rejection. A third patient developed sinusoidal obstruction syndrome following aHSCT requiring repeat liver transplantation but has no evidence of PSC recurrence while on sirolimus monotherapy now more than 3 years after aHSCT. A fourth patient was weaned off immunosuppression but died 212 days after aHSCT from pericardial constriction. A fifth patient died from multiorgan failure. Immunosuppression-free allograft acceptance was associated with deletion of T cell clones, loss of autoantibodies and increases in regulatory T cells, transitional B cells, and programmed cell death protein-1 expressing CD8+ T cells in the 2 long-term survivors.

Although operational tolerance occurred following aHSCT, the high morbidity and mortality observed renders this specific protocol unsuitable for clinical adoption.

Kidney transplant recipients are at increased risk of developing and dying from keratinocyte cancer. Risk factors for keratinocyte cancer death have not been previously described.

In a cohort of kidney transplant recipients transplanted in Queensland 1995-2014, we identified keratinocyte cancer deaths by searching national transplant and state death registries to March 2020. Standardized keratinocyte cancer mortality rates and mortality ratios were calculated. We used a competing risks model to identify factors associated with keratinocyte cancer death and calculated relative risks (RRs) and 95% confidence intervals (CIs).

There were 562 deaths in 1866 kidney transplant recipients (62% males; 86% Caucasian) with 25 934 person-years of follow-up, of which 36 were due to squamous cell carcinoma (SCC) and 1 to basal cell carcinoma (BCC) with standardized mortality rates of 78 (95% CI 53-111) and 2 (95% CI 0.1-11) per 100,000 person-years respectively. The standardized mortality ratio for keratinocyte cancer was 23 (95% CI 23-24).
