LorDist: a novel method for calculating the distance based on functional data analysis with application to longitudinal microbial data [PDF]

Microbiology Spectrum
Longitudinal human microbial data offer insights into microbiome dynamics over time. Traditional methods usually overlook temporal relationships among samples from the same subject.

Functional data analysis of heart rate variability from continuous ECG monitoring in older adults with and without mild cognitive impairment [PDF]

Frontiers in Aging Neuroscience
BackgroundReduced heart rate variability (HRV) has been associated with cognitive decline in older adults. However, prior research relied on brief in-clinic electrocardiography (ECG) recordings to measure HRV.

Semi-automated thrombin dynamics applying the ST Genesia thrombin generation assay

Frontiers in Cardiovascular Medicine, 2022
BackgroundThe haemostatic balance is an equilibrium of pro- and anticoagulant factors that work synergistically to prevent bleeding and thrombosis.

Assessing the individual roles of FII, FV, and FX activity in the thrombin generation process

Frontiers in Cardiovascular Medicine, 2022
Thrombin generation (TG) is known as a physiological approach to assess the hemostatic function. Although it correlates well with thrombosis and bleeding, in the current setup it is not sensitive to the effects of fluctuations in single coagulation ...

Longitudinal functional data analysis [PDF]

Stat, 2015
We consider dependent functional data that are correlated because of a longitudinal‐based design: each subject is observed at repeated times and at each time, a functional observation (curve) is recorded. We propose a novel parsimonious modelling framework for repeatedly observed functional observations that allows to extract low‐dimensional features ...

Tailoring the effect of antithrombin-targeting therapy in haemophilia A using in silico thrombin generation

Scientific Reports, 2021
Factor (F) VIII deficiency causes bleeding in haemophilia A patients because of the reduced formation of procoagulant enzyme thrombin, which is needed to make the blood clot.

Coagulation parameters predict COVID-19-related thrombosis in a neural network with a positive predictive value of 98%

Frontiers in Immunology, 2022
Thrombosis is a major clinical complication of COVID-19 infection. COVID-19 patients show changes in coagulation factors that indicate an important role for the coagulation system in the pathogenesis of COVID-19.

Abacavir use is associated with increased prothrombin conversion

Frontiers in Immunology, 2023
There is ongoing debate as to whether abacavir (ABC) increases the risk for cardiovascular disease(CVD) in people living with HIV (PLHIV) and the mechanisms underlying this possible association.
