A semiparametric bivariate probit model for joint modeling of outcomes in STEMI patients
No full textIn this work we analyse the relationship among in-hospital mortality and a treatment effectiveness outcome in patients affected by ST-Elevation myocardial infarction. The main idea is to carry out a joint modeling of the two outcomes applying a Semiparametric Bivariate Probit Model to data arising from a clinical registry called STEMI Archive. A realistic quantification of the relationship between outcomes can be problematic for several reasons. First, latent factors associated with hospitals organization can affect the treatment efficacy and/or interact with patient’s condition at admission time. Moreover, they can also directly influence the mortality outcome. Such factors can be hardly measurable. Thus, the use of classical estimation methods will clearly result in inconsistent or biased parameter estimates. Secondly, covariate-outcomes relationships can exhibit nonlinear patterns. Provided that proper statistical methods for model fitting in such framework are available, it is possible to employ a simultaneous estimation approach to account for unobservable confounders. Such a framework can also provide flexible covariate structures and model the whole conditional distribution of the response

Efficiency of deep core muscles training on patients with low back pain.
No full textEfficiency of Deep Core Muscles Training on Patients with Low Back Pain Vilnius University Faculty of Medicine Department of Rehabilitation, Physical and Sports Medicine Bachelor Degree of Physiotherapy Efficiency of Deep Core Muscles Strengthening Exercises on Patients with Low Back Pain Physiotherapy Bachelor's Thesis The Author: Ieva Povilauskaitė Academic advisor: Lecturer dr. Ieva Eglė Jamontaitė The aim of research work: measure the efficiency of come muscles strengthening exercises in treating lower back pain Tasks of work: 1. Compare deep core muscles strengthening exercises with conventional physiotherapy for lower back muscles strengthening. 2. Compare deep core muscles strengthening exercises with conventional physiotherapy for developing lower back range of motion. 3. Compare deep core muscles strengthening exercises with conventional physiotherapy for lowering lower back pain. Materials and methods: The research took place in Vilnius university Medicine faculty rehabilitation, physical and sport medicine cathedral and Public Enterprise VUL Santariškių clinic ambulatory rehabilitation department. The research included 20 people who were separated in two groups (10 people each). Group one was trained using deep core muscles strengthening exercises program, group two was trained using conventional physiotherapy. The parameters of research were taken at the beginning of the treatment and after 10 procedures. The parameters were compared to each other. Parameters of the treatment were taken using Dr. Wolff machine used to determine the strength of lower back muscles; Digital analog scale (SAS) used to determent the intensity of pain; Inclinometers for evaluating range of motion about a joint. Results: Muscles engaged in lower back movement in intervention group got significantly stronger (p0,05). Conclusions: Deep core muscles exercises are reliable method for lowering lower back pain. It is also a good method for strengthening muscles engaged in lower back movement and rage of motion. Both engaged group and control group methods works equally well for lowering lower back pain. Conventional physiotherapy is a better method for strengthening lower back muscles. However, deep core muscles works better for recovering lower back’s range of motion. In conclusion, deep core muscles exercises is a good method for lower back pain rehabilitation but in order to have well rounded rehabilitation it should be used combined with conventional physiotherapy

No full textAuthor of bachelor thesis: Gabija Sadauskaitė Bachelor thesis title: Young artist image creation in social media: Ieva Grigienė example The purpose of this paper work is to create young artists and her personal brand image, identity in social media. Young and unknown artist – Ieva Grigienė is keen on making her identity visible for her old and potencial clients. Also, she has the urge to tell everyone about jewelry particularity. After the theory part, which examined brand identity, social media, luxury brands, jewelry creation exceptions, a communication plan was made. 2019 on December, Ieva created her Facebook page according to communication plan. Quality analysis showed if artists aim to create her identity as young, creative and friendly person, has succeeded. During this social experiment communication experts had open questions, which required their opinion about Griga juvelyrika brand and young artist – Ieva Grigienė. Hypothesis that social media users can misunderstand or read completely different brand and jewellrer identity, wasn’t fully denied. All research participats thought that Ieva is creative and warmly communicating person but no one answered that Griga juvelyrika is a luxury brand. Though a lot luxury features were assigned to Grigienė personal brand. Analysis showed that Ieva created good impression and her personal brand provokes good emotions. Respondents gave few ideas and reccomendations how to make this brand and artists identity better, how to expand clients and followers circle. Communication plan helped Ieva Grigienė to create her and Griga juvelyrika brand identity in social media and the analysis showed how to make things better

Outlier detection for training sets in an unsupervised functional classification framework: an application to ECG signals
No full textA new method for unsupervised classification of multivariate functional data is proposed, and its application to ECG signals of PROMETEO (PROgetto sull’area Milanese Elettrocardiogrammi Teletrasferiti
dall’ Extra Ospedaliero) project is performed and discussed. In fact, classification is a challanging task
when data are curves, as well as outlier detection [1]. In particular, in the application to ECG signals
it makes possible a semi automatic diagnosis of cardiovascular diseases, based only on ECG traces morphology,
then not dependent on clinical evaluations. In [2], a real time procedure consisting of preliminary steps like reconstructing signals, wavelets denoising and removing biological variability in the signals through data registration is tuned and tested. Then, a multivariate functional k-means clustering of reconstructed and registered data is performed. Since the performances of classification method are to be validated through cross validation, it is mandatory a suitable training of the algorithm on data. Functional boxplots [4] and a multivariate extension of depth for functional data [3] are then used to detect outliers. The main focus of this work is then the application of these procedures to increase the algorithm predictive power robustifying selection criteria of data to be included in the training set, and then to perform an unsupervised multivariate functional
classification of ECG signals, based on the sole ECG’s morphology
Designing and Mining a Multicenter Observational Clinical Registry Concerning Patients with Acute Coronary Syndromes
No full textIn this work we describe design, aims, and contents of the ST-segment Elevation Myocardial Infarction (STEMI) Archive, which is a multicenter observational clinical registry planned within the Strategic Program “Exploitation, integration and study of current and future health databases in Lombardia for Acute Myocardial Infarction.” This is an observational clinical registry that collects clinical indicators, process indicators, and outcomes concerning STEMI patients admitted to any hospital of the regional district, one of the most advanced and intensive-care area in Italy. This registry is arranged to be automatically linked to the Public Health Database, the ongoing administrative datawarehouse of Regione Lombardia. Aims and perspectives of this innovative project are discussed, together with feasibility and statistical analyses which are to be performed on it, in order to monitor and evaluate the patterns of care of cardiovascular patients
