BACKGROUND Adjuvant sorafenib may enhance the efficacy of transarterial radioembolization with yttrium-90 in hepatocellular carcinoma patients. The aim of this study is to assess the efficacy and safety of radioembolization plus sorafenib in comparison to radioembolization alone. METHODS Out of 175 hepatocellular carcinoma (HCC) patients treated with radioembolization between 2011 and 2018, after propensity score matching, two groups were compared a group of 45 patients that underwent radioembolization while being on sorafenib (Group 1) and a second group of 90 patients that underwent radioembolization alone (Group 2). RESULTS Baseline characteristics of the two groups were well balanced concerning liver function and tumor burden. No significant differences in survival outcomes were identified (median overall survival 10 vs. 10 months; p = 0.711), median progression-free survival 6 vs. 7 months (p = 0.992) in Group 1 and Group 2). The objective response rate in Group 1 vs. Group 2 was 45.5% vs. 42.8% (p = 1) according to mRECIST. No differences in toxicity nor in liver decompensation rates were registered. CONCLUSIONS The association of sorafenib does not prolong survival nor delay progression in patients treated with radioembolization. Liver toxicity does not differ among the two therapeutic schemes.Heparin-induced thrombocytopenia (HIT) is an adverse drug reaction characterized by thrombocytopenia and a high risk for venous or arterial thrombosis. HIT is caused by antibodies that recognize complexes of platelet factor 4 and heparin. The pathogenic mechanisms of this condition are not fully understood. In this study, we used flow cytometry, fluorimetry, and Western blot analysis to study the direct effects of pathogenic immune complexes containing platelet factor 4 on human platelets isolated by gel-filtration. HIT-like pathogenic immune complexes initially caused pronounced activation of platelets detected by an increased expression of phosphatidylserine and P-selectin. This activation was mediated either directly through the FcγRIIA receptors or indirectly via protease-activated receptor 1 (PAR1) receptors due to thrombin generated on or near the surface of activated platelets. The immune activation was later followed by the biochemical signs of cell death, such as mitochondrial membrane depolarization, up-regulation of Bax, down-regulation of Bcl-XL, and moderate activation of procaspase 3 and increased calpain activity. The results show that platelet activation under the action of HIT-like immune complexes is accompanied by their death through complex apoptotic and calpain-dependent non-apoptotic pathways that may underlie the low platelet count in HIT. Deregulation of the transcribed ultra-conserved regions (T-UCRs) Uc160, Uc283, and Uc346 has been reported in colorectal cancer (CRC) recently. Here, we investigated promoter methylation of these T-UCRs during the adenoma-carcinoma sequence and their clinical significance in CRC patients. Methylation levels were assessed in CRC, adenomas, infiltrated lymph nodes, and metastatic tissue specimens. In situ hybridization was performed in representative tissue specimens. T-UCRs expression levels were also evaluated in HT-29 colon cancer cells before and after the acquired resistance to 5-fluorouracil (5-FU) and oxaliplatin. A gradual increase in T-UCRs methylation levels from hyperplastic polyps to adenomas and to in situ carcinomas (ISC) and a gradual decrease from ISC to infiltrative and metastatic carcinomas was observed (p less then 0.001 for Uc160 and Uc283, p = 0.018 for Uc346). UNC8153 chemical Uc160 and Uc283 methylation was associated with the grade of dysplasia in adenoma specimens (p = 0.034 and p = 0.019, respectively). Furthermore, higher Uc160 methylation, mainly in stage III and IV patients, was related to improved overall survival (OS) in univariate (p = 0.009; HR, 0.366) and multivariate analysis (p = 0.005; HR, 0.240). Similarly, higher methylation of Uc283 was associated with longer OS (p = 0.030). Finally, T-UCRs expression was significantly reduced in HT-29 cells after resistance to chemotherapy. This study suggests that promoter methylation of Uc160, Uc283, and Uc346 is altered during CRC development and that Uc160 and Uc283 methylation may have prognostic significance for CRC patients.Healthy lifestyle factors, such as physical activity (PA) and Mediterranean diet (MD), decrease the likelihood of developing metabolic syndrome (MetS). The aim of this study was to report main lifestyle components and related factors according to the MetS severity. Cross-sectional analysis was done of baseline lifestyle factors from 5739 participants with overweight/obesity and MetS features (aged 55-75 years) included in the PREDIMED-PLUS primary cardiovascular prevention randomized trial. Participants were categorized in tertiles according to a validated MetS severity score (MetSSS). Anthropometrics, visceral adiposity index, dietary nutrient intake, biochemical marker levels, as well as a Dietary Inflammatory Index and depression symptoms (Beck Depression Inventory-II) were measured. Diet quality was assessed using a 17-item energy-restricted MD questionnaire. Duration and intensity of PA was self-reported using the Minnesota-REGICOR Short Physical Activity Questionnaire. Sedentary behaviours were measured using the Spanish version of the Nurses' Health Study questionnaire. The 30 s chair stand test was also assessed. Participants with highest MetSSS showed higher values of cardiovascular risk factors (except for total cholesterol and LDL cholesterol), depression risk, sedentary and TV viewing time, and lower moderate and vigorous leisure-time physical activity (LTPA). Highest MetSSS participants tended to a pro-inflammatory dietary pattern and tended to lower MD adherence. In addition, they showed lower carbohydrate and nut intake and higher intake of protein, saturated and trans fatty acids, cholesterol, iodine, sodium, red and processed meat products, other oils different from olive oil and spirit alcoholic drinks. The highest MetS severity score was associated with lower moderate and vigorous LTPA and higher sedentary time and depression risk, as they tended to a pro-inflammatory dietary pattern and lower MD adherence.
