Lower DI (intended or relative) was associated with inferior survival in 7 of 9 studies reporting crude survival analyses. Multivariable analysis using DI as a covariate was performed in 10 studies. Six showed an association (P less then .05) with adjustment for other covariates, and 4 did not. Most studies and those larger studies of higher quality showed poorer outcomes associated with reduced DI. In subgroups aged ≥80 years, survival was not consistently affected by reduced DI. DI-specific randomized trials are warranted, but these data support full-dose R-CHOP in elderly and fit patients aged less then 80 years with DLBCL, but not in those aged ≥80 years, where dose-reduced R-CHOP does not appear to compromise survival.Circulating cardiac troponin proteins are associated with structural heart disease and predict incident cardiovascular disease in the general population. However, the genetic contribution to cardiac troponin I (cTnI) concentrations and its causal effect on cardiovascular phenotypes is unclear. We combine data from two large population-based studies, the Trøndelag Health Study and the Generation Scotland Scottish Family Health Study and perform a genome-wide association study of high-sensitivity cTnI concentrations with 48 115 individuals. We further use two-sample Mendelian randomization to investigate the causal effects of circulating cTnI on acute myocardial infarction (AMI) and heart failure (HF). We identified 12 genetic loci (8 novel) associated with cTnI concentrations. Associated protein-altering variants highlighted putative functional genes CAND2, HABP2, ANO5, APOH, FHOD3, TNFAIP2, KLKB1 and LMAN1. selleck kinase inhibitor Phenome-wide association tests in 1688 phecodes and 83 continuous traits in UK Biobank showed associations between a genetic risk score for cTnI and cardiac arrhythmias, metabolic and anthropometric measures. Using two-sample Mendelian randomization we confirmed the non-causal role of cTnI in AMI (5948 cases, 355 246 controls). We found indications for a causal role of cTnI in HF (47 309 cases and 930 014 controls), but this was not supported by secondary analyses using left ventricular mass as outcome (18 257 individuals). Our findings clarify the biology underlying the heritable contribution to circulating cTnI and support cTnI as a non-causal biomarker for AMI and HF development in the general population. Using genetically informed methods for causal inference helps inform the role and value of measuring cTnI in the general population.
To investigate survival of interleukin (IL)-1 inhibitors in monogenic autoinflammatory disorders (mAID) through drug retention rate (DRR) and identify potential predictive factors of drug survival from a real-life perspective.
Multicentre retrospective study analyzing patients affected by the most common mAID treated with anakinra or canakinumab. Survival curves were analyzed with the Kaplan-Meier method. Statistical analysis included a Cox-proportional hazard model to detect factors responsible for drug discontinuation.
Seventy-eight patients for a total of 102 treatment regimens were enrolled. The mean treatment duration was 29.59 months. The estimated DRR of IL-1 inhibitors at 12, 24, and 48 months of follow-up was 75.8%, 69.7% and 51.1%, respectively. Patients experiencing an adverse event had a significantly lower DRR (p = 0.019). In contrast, no significant differences were observed between biologic-naïve patients and those previously treated with biologic drugs (p = 0.985) Patients carrying high- given its impact on treatment continuation. Special attention should be paid to molecular diagnosis and mutation penetrance, as patients carrying low-penetrance variants are more likely to interrupt treatment.Dasatinib is a multi-target protein tyrosine kinase inhibitor. Due to its potent inhibition of Src, Abl, the platelet-derived growth factor receptor (PDGFR) family kinases, and other oncogenic kinases, it has been investigated as a targeted therapy for a broad spectrum of cancer types. However, its efficacy has not been significantly extended beyond leukemia. The mechanism of resistance to dasatinib in a wide array of cancers is not clear. In the present study, we investigated the effect of dasatinib on hepatocellular carcinoma cell growth and explored the underlying mechanisms. Our results showed that dasatinib potently inhibited the proliferation of SNU-449 cells, but not that of other cell lines, such as SK-Hep-1, even though it inhibited the phosphorylation of Src on both negative and positive regulation sites in all these cells. Dasatinib activated the phosphoinositide-dependent protein kinase1 (PDK1)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) signaling pathway in SK-Hep-1 cells, but not in SNU-449 cells. Blocking the Akt/mTOR signaling pathway strongly promoted the efficacy of dasatinib in SK-Hep-1 cells. In SNU-449 cells, dasatinib promoted apoptosis and the cleavage of caspase-3 and caspase-7, induced cell cycle arrest in the G1 phase, and inhibited the expression of Cyclin-dependent kinase (CDK4)/6/CyclinD1 complex. These findings demonstrate that dasatinib exerts its anti-proliferative effect on hepatocellular cell proliferation by blocking the Src family kinases; however, it causes Akt activation, which compromises dasatinib as an anti-cancer drug.
To report the 10-year outcome of an inception cohort of patients with early rheumatoid arthritis (RA), the ESPOIR cohort, and predictors of outcome.
From 2003 to 2005, 813 patients were included if they had early arthritis (< 6 months) with a high probability of RA and had never been prescribed DMARDs. Multivariate analysis was used to evaluate predictors of outcome.
In total, 521 (64.1%) RA patients were followed up for 10 years; 35 (4.3%) died which appears similar to the French general population. Overall, 480 (92.1%) patients received a DMARD; 174 (33.4%) received at least one biologic DMARD, 13.6% within 2 years. At year 10, 273 (52.4%) patients were in DAS28 remission, 40.1% in sustained remission, 14.1% in drug-free remission, 39.7% in CDAI remission. Half of the patients achieved a HAQ-DI < 0.5. SF-36 physical component and pain were well controlled. Structural progression was weak, with a mean change from baseline in modified Sharp score of 11.0 ± 17.9. Only 34 (6.5%) patients required major joint surgery.
