ISTRATION EudraCT 2016-001110-19 (registered 2016-08-08).PURPOSE We analysed quantitative biomarkers derived from both baseline whole-body imaging and blood serum to identify prognostic markers in patients treated within the lutetium-177 prostate-specific membrane antigen (LuPSMA) phase 2 trial. METHODS PET image analysis was carried out using whole-body segmentation quantifying molecular tumour volume (SUV > 3 threshold for PSMA, SUV > liver+2sd for fluorodeoxyglucose (FDG) including SUVmax and SUVmean. For baseline bone scans, EXINI bone scan index (BSI) was used to calculate the percentage of involved bone. Baseline alkaline phosphatase (ALP), lactate dehydrogenase (LDH), prostate specific antigen (PSA) and PSA doubling time were also used in this analysis. We used univariate cox regression analysis and log-rank comparison with optimised cut-offs to find suitable biomarkers prognostic of overall survival from time of enrolment. RESULTS This analysis identified FDG-positive tumour volume (FDGvol; HR 2.6; 95% CI, 1.4-4.8), mean intensity of PSMA-avid tumour uptake (PSMAmean; HR 0.89; 95% CI, 0.8-0.98), bone scan index (BSI; HR 2.3; 95% CI, 1.2-4.4), ALP (HR 1.1; 95% CI, 1-1.2) and LDH (HR 1.2; 95% CI, 1-1.5) as biomarkers prognostic of overall survival. CONCLUSIONS In addition to established biomarkers, both FDG and PSMA PET/CT parameters have prognostic significance for survival in men undergoing LuPSMA therapy.Rheumatoid arthritis (RA) is an inflammatory polyarthritis that typically affects the small joints but can also involve the manubriosternal joint (MSJ). Although cases of MSJ involvement in RA are rare, such cases present with chest pain, a mass-like lesion, and subluxation. These cases can also be diagnosed incidentally, while patients are asymptomatic. It is important to differentiate RA involving the MSJ from other diseases such as ankylosing spondylitis that can affect the MSJ. Several cases of RA affecting the MSJ have been reported in Western countries, but none have been reported to date in Asia, especially with disease activity of RA. Here, we report a case of RA in the MSJ that was confirmed by imaging and histological investigation in a middle-aged Asian woman.Brain donations are imperative for research; understanding possible barriers to entry is required to improve brain donation rates. While a few surveys have studied attitudes towards brain banking in patients with neurodegenerative disorders, none have surveyed patients with chronic neurological disorders but without neurodegeneration. This cross-sectional study was conducted on 187 participants, with both neurodegenerative (n = 122) and non-neurodegenerative disorders (n = 65), to compare their attitudes and preferences towards brain donation. Encouragingly, patients with non-neurodegenerative disorders were just as likely to consider brain donation as those with neurodegenerative diseases. Approximately half of each group were willing to consider brain donation, and majority of participants across both groups would not be offended if asked to participate in brain donation (71%). Across both groups, altruistic reasons such as desire to advance medical knowledge and benefit to other patients were the main motivating factors for brain donation, while perceived stress for family members, fears of body disfigurement and religious reasons were the main reasons against brain donation. Of note, nearly two-thirds of all participants were agreeable to allow their family to decide on their behalf. Overall, participants with non-neurodegenerative disorders appeared equally likely to consider brain donation as participants with neurodegenerative disorders. This is an important finding as they represent a significant population seen in specialist neurology clinics who may be overlooked in brain donor recruitment and awareness efforts. Healthcare professionals involved in brain banking should consider actively approaching these potential donors and involving their family members in these discussions.To examine whether free fatty acid receptor 4 (FFAR4) activation can protect against choroidal neovascularization (CNV), which is a common cause of blindness, and to elucidate the mechanism underlying the inhibition, we used the mouse model of laser-induced CNV to mimic angiogenic aspects of age-related macular degeneration (AMD). Laser-induced CNV was compared between groups treated with an FFAR4 agonist or vehicle, and between FFAR4 wild-type (Ffar4+/+) and knock out (Ffar4-/-) mice on a C57BL/6J/6N background. The ex vivo choroid-sprouting assay, including primary retinal pigment epithelium (RPE) and choroid, without retina was used to investigate whether FFAR4 affects choroidal angiogenesis. Western blotting for pNF-ĸB/NF-ĸB and qRT-PCR for Il-6, Il-1β, Tnf-α, Vegf, and Nf-ĸb were used to examine the influence of FFAR4 on inflammation, known to influence CNV. RPE isolated from Ffar4+/+ and Ffar4-/- mice were used to assess RPE contribution to inflammation. The FFAR4 agonist suppressed laser-induced CNV in C57BL/6J mice, and CNV increased in Ffar4-/- compared to Ffar4+/+ mice. We showed that the FFAR4 agonist acted through the FFAR4 receptor. The FFAR4 agonist suppressed mRNA expression of inflammation markers (Il-6, Il-1β) via the NF-ĸB pathway in the retina, choroid, RPE complex. The FFAR4 agonist suppressed neovascularization in the choroid-sprouting ex vivo assay and FFAR4 deficiency exacerbated sprouting. Inflammation markers were increased in primary RPE cells of Ffar4-/- mice compared with Ffar4+/+ RPE. In this mouse model, the FFAR4 agonist suppressed CNV, suggesting FFAR4 to be a new molecular target to reduce pathological angiogenesis in CNV.PURPOSE To compare the risk of cardiovascular events between patients with two CYP2C19 loss-of-function alleles who were prescribed ticagrelor or clopidogrel after percutaneous coronary intervention (PCI). METHODS Patients with two loss-of-function alleles based on the CYP2C19 genotype were selected from patients enrolled in a retrospective institutional registry. Propensity score matching using logistic regression was performed to adjust for bias between patients prescribed ticagrelor or clopidogrel. Multivariate Cox regression was used to compare the risk of adverse events in the ticagrelor and clopidogrel groups. AUZ454 order The primary outcome was the incidence of major adverse cardiac events plus any repeat target vessel revascularization within 12 months after PCI. The safety outcomes were minor and major bleeding events. RESULTS From 1518 patients carrying two loss-of-function alleles based on the CYP2C19 genotype who underwent PCI, 638 patients treated with ticagrelor or clopidogrel were successfully propensity-score matched.
