Challenges and advances for the treatment of renal cancer patients with brain metastases: From immunological background to upcoming clinical evidence…
2021
The introduction of checkpoint inhibitors (ICIs) in renal cell carcinoma (RCC) treatment landscape, resulted in improvements in overall survival (OS) in metastatic patients. Brain metastases (BMs) are a specific metastatic site of interest representing a predictive factor of poor prognosis. Patients with BMs were usually excluded from prospective clinical trials in the past. Despite recent evidence suggest the efficacy and safety of ICIs, the BMs treatment remains a challenge; the immunotherapy responsiveness seems to be multifactorial and dependent on several factors, such as the genetic intratumor heterogeneity and the immunosuppressive role of the brain tumor microenvironment. This revie…
Genomic landscape analyses in cervical carcinoma and consequences for treatment.
2020
Where we are on the road to ‘tailor-made’ precision medicine for drug-resistant cervical carcinoma? We explored studies about analyses of viral and human genomes, epigenomes and transcriptomes, DNA mutation analyses, their importance in detecting HPV sequences, mechanisms of drug resistance to established and targeted therapies with small molecule or therapeutic antibodies, to radiosensitivity and to chemoradiotherapy. The value of repurposing of old drugs initially approved for other disease indications and now considered for cervix cancer therapy is also discussed. The microbiome influences drug response and survival too. HPV genomic integration sites were less significant. Nomograms (Lee…
Is immunohistochemical evaluation of p16 in oropharyngeal cancer enough to predict the HPV positivity?
2016
Abstract Aim Our goal was to determine the expression levels of p16 in the cohort of the OPSCC patients and evaluation of the pathological and clinical differences between these two groups including patients’ survival. Background HPV infection is the main causative factor of oropharyngeal cancer (OPSCC). Identification of HPV status in OPSCC requires positive evaluation of viral DNA integration into host cell however, p16 accumulation in the proliferating cell layers has been accepted as an alternative marker for HPV infection. Material and Methods The IHC staining for p16 has been performed in tumor tissue from 382 OPSCC patients. The sample was considered positive based on more than 70% o…
Optimization of Lead Placement in the Right Ventricle During Cardiac Resynchronization Therapy. A Simulation Study
2019
[EN] Patients suffering from heart failure and left bundle branch block show electrical ventricular dyssynchrony causing an abnormal blood pumping. Cardiac resynchronization therapy (CRT) is recommended for these patients. Patients with positive therapy response normally present QRS shortening and an increased left ventricle (LV) ejection fraction. However, around one third do not respond favorably. Therefore, optimal location of pacing leads, timing delays between leads and/or choosing related biomarkers is crucial to achieve the best possible degree of ventricular synchrony during CRT application. In this study, computational modeling is used to predict the optimal location and delay of p…
Developmental transcriptomics in Atlantic haddock: Illuminating pattern formation and organogenesis in non-model vertebrates.
2016
Gadiforms such as Atlantic haddock comprise some of the world's most economically important fisheries. Understanding the early life history of these fish is a prerequisite for predicting effects of a changing environment and increased human activities. Robust assessment of the effects of environmental impacts on the embryos of non-model vertebrates is hampered by a lack of molecular resources and detailed knowledge regarding the regulation of genes and pathways in early development. Here we used mRNA sequencing to link transcriptional changes to developmental processes in haddock, specifically, pattern formation and organogenesis. Temporal expression of key developmental genes was tightly a…
PD-1 and PD-L1 expression in pulmonary carcinoid tumors and their association to tumor spread
2019
Pulmonary carcinoid (PC) tumors are rare tumors that account for approximately 1% of all lung cancers. The primary treatment option is surgery, while there is no standard treatment for metastatic disease. As the number of PCs diagnosed yearly is increasing, there is a need to establish novel therapeutic options. This study aimed to investigate programmed death protein 1 (PD-1) and programmed death ligand 1 (PD-L1) expression in PC tumors since blocking of the PD-1/PD-L1 pathway is a promising therapeutic option in various other malignancies. A total of 168 PC patients treated between 1990 and 2013 were collected from the Finnish biobanks. After re-evaluation of the tumors, 131 (78%) were cl…
Legume consumption and risk of all-cause, cardiovascular, and cancer mortality in the PREDIMED study.
2018
BACKGROUND & AIMS: Limited prospective studies have examined the association between legumes consumption and mortality, whereas scarce, if at all, previous studies have evaluated such associations taking into consideration specific grain legumes. We aimed to investigate the association between total legumes consumption and grain legumes species (dry beans, chickpeas, lentils, and fresh peas) with all-cause, cardiovascular disease (CVD), cancer and other-cause mortality among elderly Mediterranean individuals at high CVD risk. METHODS: We prospectively assessed 7216 participants from the PREvención con DIeta MEDiterránea study. Dietary intake was assessed at baseline and yearly during follow…
Plasma Metabolites Associated with Coffee Consumption: A Metabolomic Approach within the PREDIMED Study
2019
Few studies have examined the association of a wide range of metabolites with total and subtypes of coffee consumption. The aim of this study was to investigate associations of plasma metabolites with total, caffeinated, and decaffeinated coffee consumption. We also assessed the ability of metabolites to discriminate between coffee consumption categories. This is a cross-sectional analysis of 1664 participants from the PREDIMED study. Metabolites were semiquantitatively profiled using a multiplatform approach. Consumption of total coffee, caffeinated coffee and decaffeinated coffee was assessed by using a validated food frequency questionnaire. We assessed associations between 387 metabolit…
Substantial fat mass loss reduces low-grade inflammation and induces positive alteration in cardiometabolic factors in normal-weight individuals
2019
AbstractThe accumulation of fat, especially in visceral sites, is a significant risk factor for several chronic diseases with altered cardiometabolic homeostasis. We studied how intensive long-term weight loss and subsequent weight regain affect physiological changes, by longitudinally interrogating the lipid metabolism and white blood cell transcriptomic markers in healthy, normal-weight individuals. The current study examined 42 healthy, young (age: 27.5 ± 4.0 years), normal-weight (body mass index, BMI: 23.4 ± 1.7 kg/m2) female athletes, of which 25 belong to the weight loss and regain group (diet group), and 17 to the control group. Participants were evaluated, and fasting blood samples…
