Devices for the capture of rare cells from biological samples for diagnostic purposes
2022
The chance of surviving to a disease often depends on early diagnosis and effective therapy. In the field of early prenatal diagnosis, micromanipulation is a reliable technique for manual selection and isolation of rare fetal cells in maternal biological fluids for molecular or cytogenetic analysis. This technique allows obtaining pure cell populations for analysis, but it is expensive and time consuming, as it requires qualified and experienced staff and specific equipment [1]. This research aims at making the prenatal diagnosis more economical and reproducible in the hospital environment, by creating a device that allows selecting rare cells from biological samples in a semi-automated way…

MicroRNAs: Promising New Antiangiogenic Targets in Cancer
2014
[EN] MicroRNAs are one class of small, endogenous, non-coding RNAs that are approximately 22 nucleotides in length; they are very numerous, have been phylogenetically conserved, and involved in biological processes such as development, differentiation, cell proliferation, and apoptosis. MicroRNAs contribute to modulating the expression levels of specific proteins based on sequence complementarity with their target mRNA molecules and so they play a key role in both health and disease. Angiogenesis is the process of new blood vessel formation from preexisting ones, which is particularly relevant to cancer and its progression. Over the last few years, microRNAs have emerged as critical regulat…
Epigenetics and precision medicine in lung cancer
2022
Abstract Lung cancer is one of the most common types of cancer and the leading cause of cancer-related deaths worldwide. A major factor related with the high mortality rate of lung cancer patients is the late diagnosis of the disease. So, the identification and characterization of new epigenetic marks and mechanisms may contribute to better diagnose and treat lung cancer. In this chapter we review the epigenetic mechanisms involved in lung cancer, including DNA methylation, histone posttranslational modification and noncoding RNAs. The chapter focuses on biomarkers for diagnostic, prognostic and response to treatment. Finally, thanks to the reversible nature of epigenetic marks, we provide …
Recent advances of HCI in decision-making tasks for optimized clinical workflows and precision medicine.
2020
The ever-increasing amount of biomedical data is enabling new large-scale studies, even though ad hoc computational solutions are required. The most recent Machine Learning (ML) and Artificial Intelligence (AI) techniques have been achieving outstanding performance and an important impact in clinical research, aiming at precision medicine, as well as improving healthcare workflows. However, the inherent heterogeneity and uncertainty in the healthcare information sources pose new compelling challenges for clinicians in their decision-making tasks. Only the proper combination of AI and human intelligence capabilities, by explicitly taking into account effective and safe interaction paradigms,…
Effects of comprehensive geriatric assessment and targeted intervention on mobility in persons aged 75 years and over: a randomized controlled trial
2011
Objective: To assess the effect of a comprehensive geriatric assessment and individually tailored intervention on mobility in older people. In addition, the effectiveness of the geriatric intervention was evaluated among a subgroup of persons with musculoskeletal pain. Design: Three-year geriatric development project with randomized assignment to intervention and control group. Setting: Research centre, community and assisted living facilities. Participants: Seven hundred and eighty-one Finnish persons aged 75–98 years were assigned to an intervention ( n = 404) or control ( n = 377) group. Intervention: A comprehensive geriatric assessment with a multifactorial intervention lasting two ye…
ESMO Consensus Guidelines for management of patients with colon and rectal cancer. A personalized approach to clinical decision making
2012
Contains fulltext : 111010pub.pdf (Publisher’s version ) (Closed access) Colorectal cancer (CRC) is the most common tumour type in both sexes combined in Western countries. Although screening programmes including the implementation of faecal occult blood test and colonoscopy might be able to reduce mortality by removing precursor lesions and by making diagnosis at an earlier stage, the burden of disease and mortality is still high. Improvement of diagnostic and treatment options increased staging accuracy, functional outcome for early stages as well as survival. Although high quality surgery is still the mainstay of curative treatment, the management of CRC must be a multi-modal approach pe…
Colorectal cancer: pharmacogenetics support for the correct drug prescription
2019
Pharmacogenetics (PGx) in clinical practice is a tool that the clinician can use to guide, in a personalized way, the most suitable treatment that will be administered to the patient. The objective of this review is to summarize in a practical and accessible rational way, the advances that currently exist for the application of PGx in colorectal cancer chemotherapy management through the study of the patients’ germline polymorphisms. To define the polymorphisms that can be applied, we rely on three fundamental cornerstones: the recommendations of drug regulatory agencies; the implementation guidelines prepared by expert consortia in PGx and information from clinical annotations (the drug/p…
Tools for optimising pharmacotherapy in psychiatry (therapeutic drug monitoring, molecular brain imaging and pharmacogenetic tests): focus on antidep…
2021
Contains fulltext : 238693.pdf (Publisher’s version ) (Open Access) Objectives: More than 40 drugs are available to treat affective disorders. Individual selection of the optimal drug and dose is required to attain the highest possible efficacy and acceptable tolerability for every patient.Methods: This review, which includes more than 500 articles selected by 30 experts, combines relevant knowledge on studies investigating the pharmacokinetics, pharmacodynamics and pharmacogenetics of 33 antidepressant drugs and of 4 drugs approved for augmentation in cases of insufficient response to antidepressant monotherapy. Such studies typically measure drug concentrations in blood (i.e. therapeutic …
Non-coding RNAs and Coronary Artery Disease
2020
Coronary artery disease (CAD) is the leading death cause worldwide. Non-coding RNA (ncRNA) are key regulators of genetic expression and thus can affect directly or indirectly the development and progression of different diseases. ncRNA can be classified in several types depending on the length or structure, as long non-coding RNA (lncRNA), microRNA (miRNA) and circularRNA (circRNA), among others. These types of RNA are present within cells or in circulation, and for this reason they have been used as biomarkers of different diseases, therefore revolutionizing precision medicine. Recent research studied the capability of circulating ncRNA to inform about CAD presence and predict the outcome …
