Agent-based model for the rescheduling of Individual and collective daily activities under uncertainties
2020
Daily activity schedule are popular for people duringdaily life. While, when executing the schedule on the real road network, there are always some disruptions disturbing the planned schedule. To deal with this problem, daily activity rescheduling is necessary. This thesis regards the disruptions from the activity schedule execution environment as unexpected events (uncertainties). It establishes agent-based models to simulate the activity rescheduling decision process from the aspects of individual activity rescheduling and joint trip renegotiating.For the individual activity rescheduling, the model in this thesis wants to explore the relationship between a pair of episodes (two connected …
Spatio-temporal log-Gaussian Cox processes on eartquake events
2017
In this paper we aim at studying some extensions of complex space-time models, useful for the description of earthquake data. In particular we want to focus on the Log-Gaussian Cox Process (LGCP) model estimation approach, with some results on global informal diagnostics. Indeed, in our opinion the use of Cox processes that are natural models for point process phenomena that are environmentally driven could be a new approach for the description of seismic events. These models can be useful in estimating the intensity surface of a spatio-temporal point process, in constructing spatially continuous maps of earthquake risk from spatially discrete data, and in real-time seismic activity surveil…
Bone metastases in soft tissue sarcoma: a survey of natural history, prognostic value and treatment options
2013
Abstract Background We surveyed the natural history of bone metastases in patients affected by soft tissue sarcoma (STS). Methods This multicenter retrospective observational study included 135 patients. Histological subtype, characteristics of bone metastases, treatment, skeletal related events (SREs) and disease outcome were recorded. Results The most represented histological subtypes were leiomyosarcoma (27%) angiosarcoma (13%) and undifferentiated sarcoma (8%). Axial skeleton was the most common site for bone involvement (70%). In 27% of cases, bone metastases were present at the time of diagnosis. Fifty-four (40%) patients developed SREs and the median time to first SRE was 4 months (r…
Latvijas Bibliotekāru biedrība: vēsturiskie notikumi un jaunāko gadu norises
2022
Maģistra darba mērķis ir izpētīt ar Latvijas Bibliotekāru biedrību (LBB) un tās valdi saistītus vēsturiskos notikumus, to veidus un pārmaiņu tendences laika posmā no LBB dibināšanas 1923. gadā līdz 2014. gadam un izstrādāt biedrības notikumu hronoloģiju, kā arī pētīt viedokļus par LBB jaunāko gadu (2014.–2021. gada) norisēm, jo līdz šim informācija bijusi pieejama tikai izkliedētā vai daļēji apkopotā veidā. Pētījums izstrādāts, pētot vēsturiskos un sociālos procesus skaidrojošas teorijas (vēsturiskuma metateorija un sociālās apmaiņas teorija), veicot arhīva dokumentu, rakstu periodikā un citu publikāciju analīzi un ekspertu – LBB valdes locekļu un biedru – anketēšanu. Darba rezultātā apkopo…
A Genetic and Metabolic Staging System for Predicting the Outcome of Nonalcoholic Fatty Liver Disease
2022
Nonalcoholic fatty liver disease (NAFLD) is an emerging cause of liver-related events (LREs). Here, we have assessed the ability of a composite score based on clinical features, metabolic comorbidities, and genetic variants to predict LREs. A total of 546 consecutive patients with NAFLD were recruited and stratified according to the fibrosis-4 (FIB-4) index. LREs were defined as occurrence of hepatocellular carcinoma or hepatic decompensation. Cox regression multivariate analysis was used to identify baseline variables associated with LREs. The UK Biobank was used as the validation cohort, and severe liver disease (incidence of cirrhosis, decompensated liver disease, hepatocellular carcinom…
A cholestatic pattern predicts major liver-related outcomes in patients with non-alcoholic fatty liver disease
2022
NAFLD patients usually have an increase in AST/ALT levels, but cholestasis can also be observed. We aimed to assess in subjects with NAFLD the impact of the (cholestatic) C pattern on the likelihood of developing major liver-related outcomes (MALO).
Stress and neuroticism in Spanish nursing students: A two-wave longitudinal study
2012
The aim of this study was to clarify the direction of the stress� neuroticism relationship in a sample of 200 nursing students from three Spanish universities before their entry into the work force using a twowave longitudinal design. The Stressful Life Events Scale and NEO-FFI Neuroticism subscale were administered at the beginning (T1) and end (T2) of nursing studies. Female students reported higher scores in both perceived stress due to life events and neuroticism than males. Older students scored higher in life events stress than younger ones. High neuroticism was associated with a high level of stress. Finally, neuroticism scores rose in the group in which stress increased from T1 to T…
Effect of Rivaroxaban and Aspirin in Patients With Peripheral Artery Disease Undergoing Surgical Revascularization: Insights From the VOYAGER PAD Tri…
2021
Background: Patients with peripheral artery disease requiring lower extremity revascularization (LER) are at high risk of adverse limb and cardiovascular events. The VOYAGER PAD trial (Vascular Outcomes Study of ASA [Acetylsalicylic Acid] Along With Rivaroxaban in Endovascular or Surgical Limb Revascularization for PAD) demonstrated that rivaroxaban significantly reduced this risk. The efficacy and safety of rivaroxaban has not been described in patients who underwent surgical LER. Methods: The VOYAGER PAD trial randomized patients with peripheral artery disease after surgical and endovascular LER to rivaroxaban 2.5 mg twice daily plus aspirin or matching placebo plus aspirin and followed …
Impact of frailty and atrial fibrillation in elderly patients with acute coronary syndromes
2021
Background: There is scarce information on the prognostic role of frailty and Atrial Fibrillation (AF) in elderly patients Acute Coronary Syndrome (ACS). Methods: The aim was to analyse the management of elderly patients with frailty and AF who suffered an ACS using data of the prospective multicentre LONGEVO-SCA registry. We evaluated the predictive performance of FRAIL, Charlson scores and AF status for adverse events at 6 months follow-up. Results: A total of 531 unselected patients with ACS and above 80 years old [mean age 84.4 (SD=3.6) years; 322 (60.6%) male] were enrolled, of whom 128 (24.1%) with AF and 145 (27.3%) with frailty. Mutually exclusive number of patients were as follows:…
Management of Oral Anti-Coagulation in Patients with Heart Failure-Insights from the ThrombEVAL Study
2018
AbstractPatients with heart failure (HF) are frequently anti-coagulated with vitamin K-antagonists (VKAs). The use of long-acting VKA may be preferable for HF patients due to higher stability of plasma concentrations. However, evidence on phenprocoumon-based oral anti-coagulation (OAC) therapy in HF is scarce. The aim of this study was to assess the impact of the presence of HF on quality of phenprocoumon-based OAC and the subsequent clinical outcome. Quality of OAC therapy and the incidence of adverse events were analysed in a cohort of regular care (n = 2,011) from the multi-centre thrombEVAL study program (NCT01809015) stratified by the presence of HF. To assess the modifiability of outc…
