45, 95%CI, 1.11-1.90). TST-QFT+ results were associated with increasing age, male sex, smoking, and diagnosed diabetes. Compared to participants with TST-QFT- results, QFT+ and TST+QFT+ participants were 6.3 (95%CI, 1.9-20.4) and 7.5 (95%CI, 2.3-25.1) times more likely to progress to tuberculosis. CONCLUSIONS In this population-based study of over 5000 participants from a medium tuberculosis burden region, test agreement between QFT and TST was fair overall, and we found multiple novel predictors of discordant QFT/TST test results. QFT provides a substantial improvement to the TST among these populations and was multi-fold better predictive of progression to tuberculosis. © The Author(s) 2020.

OBJECTIVE We hypothesized that tomato or lycopene products would reduce the emergence of CRPC. METHODS Transgenic adenocarcinoma of the mouse prostate (TRAMP) mice were castrated at 12-13 wk and the emergence of CRPC was monitored by ultrasound in each study. In Study 1, TRAMP mice (n = 80) were weaned onto an AIN-93G-based control diet (Con-L, n = 28), a 10% tomato powder diet (TP-L, 10% lyophilized w/w, n = 26), or a control diet followed by a tomato powder diet after castration (TP-Int1, n = 26). In Study 2, TRAMP mice (n = 85) were randomized onto a control diet with placebo beadlets (Con-Int, n = 29), a tomato diet with placebo beadlets (TP-Int2, n = 29), or a control diet with lycopene beadlets (Lyc-Int, n = 27) following castration (aged 12 wk). Tumor incidence and growth were monitored by ultrasound beginning at an age of 10 wk. Mice were euthanized 4 wk after tumor detection or aged 30 wk if no tumor was detected. Tissue weights were compared by ANOVA followed by Dunnett's test. Tumor volumes were compared using generalized linear mixed model regression. RESULTS Ultrasound estimates for the in vivo tumor volume were strongly correlated with tumor weight at necropsy (R2 = 0.75 and 0.94, P less then 0.001 for both Studies 1 and 2, respectively). Dietary treatments after castration did not significantly impact cancer incidence, time to tumor detection, or final tumor weight. CONCLUSIONS In contrast to studies of de novo carcinogenesis in multiple preclinical models, tomato components had no significant impact on the emergence of CRPC in the TRAMP model. It is possible that specific mutant subclones of prostate cancer may continue to show some antiproliferative response to tomato components, but further studies are needed to confirm this.

Leaks are prevented by contractile actin filaments surrounding the diapedesis-pore keeping this opening tightly closed around the transmigrating neutrophils. Here, we have identified the receptor system which is responsible for this. BGJ398 We show that silencing, or gene inactivation of endothelial Tie-2 each result in leak formation in postcapillary venules of the inflamed cremaster at sites of neutrophil extravasation as visualized by fluorescent microspheres. Leakage was dependent on neutrophil extravasation, since it was absent upon neutrophil depletion. As downstream target of Tie-2 we identified the Cdc42 GTPase exchange factor FGD5 as essential for leakage prevention during neutrophil extravasation. Seeking for the Tie-2 agonist and its source we found that platelet derived Angiopoietin-1 was required to prevent neutrophil-induced leaks. Intriguingly, blocking von Willebrand Factor (VWF) resulted in vascular leaks during transmigration, indicating that platelets interacting with endothelial VWF activate Tie‑2 by secreting Angiopoietin-1, thereby preventing diapedesis-induced leakiness.

The aim of the present 6-months follow-up convenience-sampled cohort study was to assess the efficacy of LLLT as an adjunct to NSMD in the treatment of peri-implantitis. A questionnaire was used to collect demographic information. Patients with peri-implantitis in the test-and control groups underwent NSMD with and without adjunct LLLT, respectively. Randomization was done by tossing a coin. In the test group, the laser was applied perpendicularly to the periodontal pocket for 20 seconds at a constant distance of 15 mm and with a continuous wavelength (3.41 J/cm2 delivery with a 1.76 cm2 spot and average output of 0.3 W). In both groups, peri-implant probing depth, bleeding upon probing and crestal bone resorption were assessed at baseline and at 3- and 6-months' follow-up. Group comparisons were performed and P less then 0.05 was considered statistically significant. Sixty-seven individuals with peri-implantitis were included. The mean age of individuals that underwent NSMD with adjunct LLLT and NSMD alone 46.5±3.4 and 45.3±1.1 years, respectively. At 3 and 6-months' follow-up, peri-implant PI (P less then 0.05), BUP (P less then 0.05) and PrD (P less then 0.05) were significantly higher among patients that underwent NSMD alone compared with individuals that underwent NSMD with adjunct LLLT. There was no significant difference in CBR in all patients up to 6-months' follow-up. In the short-term, NSMD with adjunct LLLT is a useful treatment protocol for the treatment of peri-implant soft-tissue inflammation.The objective of this study is to assess alterations in buccal soft tissue contour after alveolar ridge preservation (ARP) using either a collagen matrix seal (CMS) or a collagen sponge (CS) as barriers with freeze-dried bone allograft (FDBA). Participants (28 total) were randomly assigned into the CMS group or the CS group (14 each). The same clinical steps were used in both barriers. Cast models were taken at the baseline and at 4 months, then both models were optically scanned and digitally superimposed. Volumetric, surface, and distance-adjusted measurements were calculated to assess buccal soft tissues alterations. Surface area and volume loss in the CMS group were observed to be 71.44±1189.09 mm 2 and 239.58±231.89 mm 3 . The CS group showed measurements of 139.56±557.92 mm 2 and 337.23±310.18 mm 3, . Mean buccal soft tissue loss and minimum-maximum distance loss were less in the CMS (0.88±0.52 mm, and 0.2-2.15 mm respectively), compared with the CS group (1.63±1.03 mm and 0.3-3.68 mm respectively) with no statistically significant difference between the groups (p=0.
