Spatio‑temporal modelling of high‑throughput phenotyping data
(2023-10-13)
High throughput phenotyping (HTP) platforms and devices are increasingly used to characterise growth and developmental processes for large sets of plant genotypes. This dissertation is motivated by the need to accurately ...
Derivative curve estimation in longitudinal studies using P-splines
(2023-09-18)
The estimation of curve derivatives is of interest in many disciplines. It allows the extraction of important characteristics to gain insight about the underlying process. In the context of longitudinal data, the derivative ...
Competing risk modelling for in-hospital length of stay
(2023-07)
In this study, we propose a framework for analysing in-hospital patient data from electronic health records. We transform longitudinal sparse vital signs measurements into cross-sectional data via descriptive statistics, ...
Competing risk models in early warning systems for in-hospital deterioration: the role of missing data imputation
(2023-06)
Early Warning Systems (EWS) are useful and very important tools for evaluating the health deteriorating of hospitalised patients, using vital signs (such as heart rate, temperature, etc.) as the main input, based on ...
Impact of outdoor air pollution on severity and mortality in COVID-19 pneumonia
(2023-06)
The relationship between exposure to air pollution and the severity of coronavirus disease 2019 (COVID-19) pneumonia and other outcomes is poorly understood. Beyond age and comorbidity, risk factors for adverse outcomes ...
Automated location of orofacial landmarks to characterize airway morphology in anaesthesia via deep convolutional neural networks
(2023-04)
Background:A reliable anticipation of a difficult airway may notably enhance safety during anaesthesia. In current practice, clinicians use bedside screenings by manual measurements of patients’ morphology.
Objective:To ...
Five-year follow-up mortality prognostic index for colorectal patients
(2023)
Purpose: To identify 5-year survival prognostic variables in patients with colorectal cancer (CRC) and to propose a survival prognostic score that also takes into account changes over time in the patient's health-related ...
Variable selection with LASSO regression for complex survey data
(2023)
Variable selection is an important step to end up with good prediction models. LASSO regression
models are one of the most commonly used methods for this purpose, for which
cross-validation is the most widely applied ...
Age or lifestyle-induced accumulation of genotoxicity is associated with a length-dependent decrease in gene expression
(2023)
DNA damage has long been advocated as a molecular driver of aging. DNA dam-
age occurs in a stochastic manner, and is therefore more likely to accumulate in longer genes. The length-dependent accumulation of transcripti ...
Clinical prediction rules for adverse evolution in patients with COVID-19 by the Omicron variant
(2023)
Objective: We identify factors related to SARS-CoV-2 infection linked to hospitalization, ICU admission, and mortality and develop clinical prediction rules.
Methods: Retrospective cohort study of 380,081 patients with ...
