In both experiments we found that attention was more often captured by the distractor signalling the valuable (non-sated) outcome, replicating previous studies using this paradigm with monetary rewards. We also found that those scoring high on eating restraint (as measured with the Dutch Eating Behavior Questionnaire) were better at controlling reflexive orienting of attention to desirable food rewards. This paradigm offers a novel approach for understanding how reflexive attention and control relate to conflicts in everyday life around distracting food cues, and the moderating role of dietary restraint.

The cystic fibrosis transmembrane conductance regulator (CFTR) potentiator, ivacaftor, was first approved for people with CF and the G551D CFTR mutation. This study describes the long-term clinical effectiveness of ivacaftor in this population.

We conducted a multicenter, prospective, longitudinal, observational study of people with CF ages ≥6 years with at least one copy of the G551D CFTR mutation. Measurements of lung function, growth, quality of life, and sweat chloride were performed after ivacaftor initiation (baseline, 1 month, 3 months, 6 months, and annually thereafter until 5.5 years).

Ninety-six participants were enrolled, with 81% completing all study measures through 5.5 years. This cohort experienced significant improvements in percent predicted forced expiratory volume in 1second (ppFEV1) of 4.8 [2.6, 7.1] (p<0.001) at 1.5 years, that diminished to 0.8 [-2.0, 3.6] (p=0.57) at 5.5 years. Adults experienced larger improvements in ppFEV1 (7.4 [3.6, 11.3], p<0.001 at 1.5 years and 4.3 [0.6, 8.1], p=0.02 at 5.5 years) than children (2.8 [0.1, 5.6], p=0.04 at 1.5 years and -2.0 [-5.9, 2.0], p=0.32 at 5.5 years). Rate of lung function decline for the overall study cohort from 1 month after ivacaftor initiation through 5.5 years was estimated to be -1.22 pp/year [-1.70, -0.73]. Significant improvements in growth, quality of life measures, sweat chloride, Pseudomonas aeruginosa detection, and pulmonary exacerbation rates requiring antimicrobial therapy persisted through five years of therapy.

These findings demonstrate the long-term benefits and disease modifying effects of ivacaftor in children and adults with CF and the G551D mutation.

Previous in vitro organoid data showed A455E-CFTR, a rare CFTR mutation with 4.1% prevalence in the Netherlands, responds to lumacaftor/ivacaftor (LUM/IVA). We explored LUM/IVA's clinical efficacy in people with CF and ≥1 A455E-CFTR mutation.

Participants aged ≥12 years were randomized to 1 of 2 treatment sequences (LUM/IVA→placebo or placebo→LUM/IVA) with an 8-week washout period between. Primary endpoint was absolute change in ppFEV

from study baseline through 8 weeks. Additional endpoints were change in sweat chloride concentration (SwCl) and CFQ-R respiratory domain score. Correlations between organoid-based measurements and clinical endpoints were investigated.

Twenty participants were randomized at 2 sites in the Netherlands. Mean absolute change in ppFEV

from study baseline through Week 8 showed a treatment difference of 0.1 percentage points (95% CI, -2.5 to 2.7; P=0.928) between LUM/IVA (within-group mean change, 2.7) and placebo (within-group mean change, 2.6). The mean absolute change in cipants with CF and ≥1 A455E-CFTR mutation. The primary endpoint (ppFEV1) did not show a statistically significant difference between LUM/IVA and placebo; correlations between in vitro and in vivo responses were not established (NCT03061331).Despite continuous exertion made, colon cancer still represents a major health problem and its incidence continues being high worldwide. There is growing evidence in support of the cancer stem cells (CSCs) being central in the initiation of this cancer, and CSCs have been the focus of various studies for the identification of new ways of treatment. Lately, the proprotein convertases (PCs) were reported to regulate the maturation and expression of various molecules involved in the malignant phenotype of colon cancer cells, however, the identity of the molecules regulated by these serine proteases in CSCs is unknown. 2,6-Dihydroxypurine purchase In this study, we used the general PCs inhibitor, the Decanoyl-RVKR-chloromethylketone (Decanoyl-RVKR-CMK) that inhibits all the PCs found in the secretory pathway, and analyzed its effect on CSCs using RNA-seq analysis. Remarkably, from the only 9 up-regulated genes in the human SW620-derived sphere-forming cells, we identified 7 of the 11 human metallothioneins, all of them localized on chromosome 16, and zinc related proteins as downstream effectors of the PCs. The importance of these molecules in the regulation of cell proliferation, differentiation and chemoresistance, and their reported potential tumor suppressor role and loss in colon cancer patients associated with worse prognosis, suggests that targeting PCs in the control of the malignant phenotype of CSCs is a new potential therapeutic strategy in colon cancer.Urinary albumin is one of the main markers used in clinical practice to assess kidney damage. It is usually measured in laboratories through immunological assays, but these assays may not detect molecules with conformational changes, such as carbamylated albumin/proteins. Therefore, this study aimed to investigate the impact of albumin carbamylation on the measurement of albuminuria by an immunoturbidimetric assay. The addition of the carbamylating agent to PBS buffer and urine pool promoted a lower quantification of albumin measured by the immunoturbidimetric method, indicating that this process may be responsible for an underestimation of the results in clinical practice.

Mediastinitis is a serious complication of open-heart surgery associated with high mortality, considerable healthcare costs and prolonged hospital stay. We examined characteristics and incidence of mediastinitis during 29 years when indications and patient material have been in a process of change.

A retrospective population-based study comprising all mediastinitis patients over 16 years of age after open-heart surgery between 1990-2018 from a population of 1.7 million. Patient records of 50 mediastinitis patients from 2004-2014 were reviewed and compared to 120 patients from 1990-1999.

Annual mediastinitis rate varied 0-1.5 % with a decreasing trend - from a level exceeding 1.2 % to about 0.3 % - over the study period. In 2004-2014 patients with mediastinitis were older, more often smokers, had more often diabetes and renal insufficiency than in 1990-1999. No difference in length of hospital treatment, antibiotic prophylaxis or treatment, ICU treatment or mortality was observed between 1990-1999 and 2004-2014. CABG became less common and valve replacement and hybrid operations more common among operations leading to mediastinitis. Staphylococcus aureus increased (from 25% to 56%, p = 0.005) while coagulase negative staphylococci (46% to 23%, p < 0.001) and Gram-negative bacteria (18% to 12%, p = 0.033) decreased as causative agents. Surgery for mediastinitis remained similar except introduction of vacuum assisted closure treatment.

The rate of mediastinitis decreased during these 29 years. No difference in 30-day mortality in mediastinitis was seen, 0.9 % in 1990-1999 and 2.0 % in 2004-2014.

Cerebral malperfusion and carotid artery dissection in patients with acute type A aortic dissections (TAAD) carry high morbidity and mortality. There are limited data on outcomes of concomitant carotid artery replacement with total arch replacement in the setting of a TAAD.

All patients with acute TAAD who underwent a total arch replacement (TAR) between 2007 and 2018 were included. Data were retrospectively collected from a prospectively maintained database. Baselines variables were compared, and Kaplan-Meier estimates were used for long term survival. Cox multivariable regression analysis was used to identify predictors of mortality.

A total of 161 patients underwent TAR for acute TAAD. Of these, 111 underwent conventional total arch reconstruction, while 50 had a concomitant carotid artery replacement. Baseline characteristics were similar between both cohorts apart from the carotid replacement cohort having a higher rate of preoperative cerebral malperfusion (48% vs 10.81%; p<0.01) and pre-operative stroke (28% vs 11.71%; p=0.02). There was no difference in (operative) 30-day mortality between the carotid replacement and conventional TAR groups (22% vs 18.9%; p=0.81), 1-year mortality (28% vs 27.9%; p=0.99) or 5-year (32% vs 29.7%; p=0.917) mortality. Postoperative stroke was 0% vs 4.5% (p=0.301) for the carotid vs conventional TAR cohort.

Concomitant carotid artery replacement is a feasible and safe technique to address perioperative cerebral malperfusion, carotid dissection and neurologic dysfunction associated with carotid artery dissection, with no difference in long term survival or postoperative stroke when compared to conventional TAR.

The prognostic role of PD-L1 in malignant pleural mesothelioma (MPM) is incompletely understood. Our objectives were to evaluate the evidence for tumor PD-L1 as a prognostic biomarker in MPM through meta-analysis and to determine if tumor PD-L1 expression is associated with survival in MPM patients undergoing macroscopic complete resection.

Meta-analysis was performed to determine the association of PD-L1 with overall survival (OS) in MPM (n=1,655) from fourteen studies containing OS and tumor PD-L1 expression. Univariable and multivariable analyses tested the relationship of tumor PD-L1 with OS and recurrence-free survival (RFS) in an institutional cohort of MPM patients treated by macroscopic complete resection (n=75). To validate the association of PD-L1 with OS, we utilized two independent MPM cohorts (n=284).

Meta-analysis demonstrated that high tumor PD-L1 expression was associated with poor OS. Among 75 patients undergoing macroscopic complete resection, 49 tumors (65%) expressed PD-L1 (≥1%), and high PD-L1 (≥50%) was more commonly expressed on non-epithelial (29%) compared with epithelial tumors (14%). High tumor PD-L1 expression was independently associated with poor OS (P<0.001, HR=5.67) and RFS (P=0.003, HR=3.28). The association of PD-L1 overexpression with unfavorable survival was more significant in epithelial MPMs than non-epithelial MPMs. These findings were validated in RNA sequencing analyses in two independent cohorts. Exploratory transcriptome analysis revealed that MPM tumors with PD-L1 overexpression displayed co-expression of other immune regulatory molecules, PD-L2 and TIM-3.

Tumor PD-L1 expression is a prognostic biomarker in patients undergoing surgical resection for MPM and may be useful in perioperative decision making.
