A Tool for Optimizing De-Identified Health Data for Use in Statistical Classification

Abstract:

When individual-level health data is shared in biomedical research the privacy of patients and probands must be protected. This is typically achieved with methods of data de-identification, which transform data in such a way that formal guarantees about the degree of protection from re-identification can be provided. In the process it is important to minimize loss of information to ensure that the resulting data is useful. A typical use case is the creation of predictive models for knowledge discovery and decision support, e.g. to infer diagnoses or to predict outcomes of therapies.

A Recall Analysis of Core Word Lists over Children’s Utterances for Augmentative and Alternative Communication

Abstract:

The vocabulary definition is of paramount importance in the customization of AAC devices, and it can be based on core word lists proposals. However, despite having the same purpose, there is no consensus among these core word lists. Therefore, in order to present evidence that helps to decide which list has a better recall, in this paper, 9 core word lists for children were reviewed; in addition, a Super List by merging these 9 lists was made.

Computational Analysis of BRCA1 Mutations in Pediatric Patients with Malignancies and Their Mothers

Abstract:

Breast and ovarian cancers are the most prevalent amongst women. Similar incidence appear in childhood malignancies, where the basic ontogenetic mechanisms still remain to be elucidated. Such approaches, of relating mother’s cancer mutations with the prevalence of childhood cancer in their offspring could prove useful in the prognosis, early detection and therapy of childhood malignancies. The aim of the present study was to use computational and bioinformatics tools to investigate the incidence of mutations in mothers with children suffering from neoplasms.

Multi-Label Modality Classification for Figures in Biomedical Literature

Abstract:

The figures found in biomedical literature are a vital part of biomedical research, education and clinical decision. The multitude of their modalities and the lack of corresponding meta-data, constitute search and information retrieval a difficult task. We present multi-label modality classification approaches for biomedical figures. In particular, we investigate using both simple and compound figures for training a multi-label model to be used for annotating either all figures, or only those predicted as compound by an initial compound figure detection model.

Personalization of Infectious Disease Risk Prediction: Towards Automatic Generation of a Bayesian Network

Abstract:

Infectious diseases have been a major cause of human morbidity, but most are avoidable. A relevant and accurate risk prediction is expected to alert people to the risk of getting exposed to infectious diseases. However, current approaches are limited to the contexts and static risk prediction model. Thus, a dynamic and growing prediction model, based on Bayesian Network (BN), is proposed to overcome these limitations.

BREATH: Heat Maps Assisting the Detection of Abnormal Lung Regions in CT Scans

Abstract:

Computed Tomography (CT) scans are often employed to diagnose lung diseases, as abnormal tissue regions may indicate whether proper treatment is required. However, detecting specific regions containing abnormalities in a CT scan demands time and effort of specialists. Moreover, different parts of a single lung image may present both normal and abnormal characteristics, what makes inaccurate the classification of a single lung as healthy (normal) or not.

iManageCancer:Empowering patients and strengthening self-management in cancer diseases

Abstract:

Cancer research has led to more cancer patients being cured, and many more enabled to live with their cancer. As such, some cancers are now considered a chronic disease, where patients and their families face the challenge to take an active role in their own care and in some cases in their treatment. To this direction the iManageCancer project aims to provide a cancer specific self-management platform designed according to the needs of patient groups while focusing, in parallel, on the wellbeing of the cancer patient.

The Design of a Mobile App for Promotion of Physical Activity and Self-Management in Prostate Cancer Survivors: Personas, Feature Ideation and Low-Fidelity Prototyping

Abstract:

"Most prostate cancer survivors are confronted with disease-related and treatment-related side effects that impact their quality of life. A tool that combines specific physical activity coaching with the promotion of a healthy lifestyle and self-management guidance might be a successful method to enhance a lifestyle change in these patients. As a prerequisite for useful health technology, it is important to consider a design process centred in the patients.

The application of neuromuscular electrical stimulation (NMES) technologies in cancer care

Abstract:

Despite the increase in long term cancer survivors, successful treatment is associated with significant sequelae. As a result, participation in voluntary exercise becomes difficult highlighting the need for pragmatic alternatives. Neuromuscular electrical stimulation (NMES) has been shown as effective in pathological conditions for improving muscle strength. However, its use in cancer care is sparse and has provided equivocal results. This paper outlines a proposed approach to the design, development, evaluation and implementation of NMES technology into cancer pathways.

An Error Aware SSVEP-based BCI

Abstract:

ErrPs have been used lately in order to improve several existing BCI applications. In our study we investigate the contribution of ErrPs in a SSVEP based BCI. An extensive study is presented in order to discover the limitations of the proposed scheme. Using Common Spatial Patterns and Random Forests we manage to show encouraging results regarding the incorporation of ErrPs in a SSVEP system. Finally, we provide a novel methodology (ICRT) that can measure the gain of a BCI system by incorporating ErrPs in terms of time efficiency.

Analyzing the Impact of Cognitive Load in Evaluating Gaze-based Typing

Abstract:

Gaze-based virtual keyboards allow people with motor disability a method for text entry by eye movements. The effectiveness and usability of these keyboards have traditionally been evaluated with conventional text entry performance measures such as words per minute, keystroke saving, error rate, accuracy, etc. However, in comparison to the conventional text entry approaches, gaze-based typing involves natural eye movements that are highly correlated with human brain cognition.

Assessing the Usability of Gaze-Adapted Interface against Conventional Eye-Based Input Emulation

Abstract:

In recent years, eye tracking systems have greatly improved, beginning to play a promising role as an input medium. Eye trackers can be used for application control either by simply emulating the mouse device in the traditional graphical user interface, or by customized interfaces for eye gaze events. In this work we evaluate these two approaches to assess their impact in usability. We present a gaze-adapted Twitter application interface with direct interaction of eye gaze input, and compare it to the Twitter in a conventional browser interface with gaze-based mouse and keyboard emulation.

EEG Signal Analysis of Real-word Reading and Nonsense-word Reading between Adults with Dyslexia and without Dyslexia

Abstract:

The evolution in technology plays a major role in improving diagnostic accuracies. Pattern recognition and classification are techniques that may help uncover answers that are not always obvious. This paper attempts to discover such patterns found in brain wave signals in people with dyslexia using classifiers. Electroencephalogram (EEG) signals captured during real-word and nonsense-word reading activities from individuals with dyslexia are compared with normal controls.

Emotional state recognition using advanced machine learning techniques on EEG data

Abstract:

This study investigates the discrimination between calm, exciting positive and exciting negative emotional states using EEG signals. Towards this direction, a publicly available dataset from eNTERFACE Workshop 2006 was used having as stimuli emotionally evocative images. At first, EEG features were extracted based on literature review. Then, a computational framework is proposed using machine learning techniques, performing feature selection and classification into two at a time emotional states.

Exploiting active microRNA interactions for diagnosis from expression profiling experiments

Abstract:

In silico diagnosis through microRNA expression profiling experiments is a promising direction in the clinical practices of bioinformatics science. The task is computationally defined as a classification problem where a query experiment is required to be assigned into one of the predefined diseases using a learned model from previously labeled samples. While several powerful machine learning models exist to perform this task, the challenging issue is how to feed these models by effectively encoded samples. This encoding requires a sensible representation of experiment content.

The Effect of Mammogram Preprocessing on Microcalcification Detection with Convolutional Neural Networks

Abstract:

"Microcalcifications are an early mammographic indicator of breast cancer. To assist screening radiologists in reading mammograms, machine learning techniques have been developed for the automated detection of microcalcifications. In the last few years, Convolutional Neural Networks (CNNs) have achieved state-of-the-art performance in many computer vision and medical image analysis applications. A key step in CNN-based detection is image preprocessing, including brightness and contrast variations.

Secure Database Outsourcing to the Cloud: Side-Channels, Counter-Measures and Trusted Execution

Abstract:

"Outsourcing data processing and storage to the cloud is a persistent trend in the last years. Cloud computing offers many advantages like flexibility in resource allocation, cost reduction and high availability. However, when sensitive information is handed to a third party, security questions are raised since the cloud provider and his employees are not fully trusted. Standard security mechanisms like transport encryption and regular audits alone can't solve the issue of insider attacks. Additional cryptographic techniques are required. In this paper we build upon an existing

Ontological Templates for Regulating Access to Sensitive Medical Data in the Cloud

Abstract:

By embracing the cloud computing paradigm for storing and processing electronic medical records (EMRs), modern healthcare providers are able to realise significant cost savings. However, relinquishing control of sensitive medical data by delegating their storage and processing to third-party cloud providers naturally raises significant security concerns. One way to alleviate these concerns is to devise appropriate policies that infuse adequate access controls in cloud services.

HealthShare: Using Attribute-Based Encryption for Secure Data Sharing Between Multiple Clouds

Abstract:

"In this paper, we propose HealthShare –a forwardlooking approach for secure ehealth data sharing between multiple organizations that are hosting patients’ data in different clouds. The proposed protocol is based on a Revocable Key-Policy Attribute-Based Encryption scheme and allows users to share encrypted health records based on a policy that has been defined by the data owner (i.e. patient, a member of the hospital, etc). Furthermore, access to a malicious or compromised user/organization can be easily revoked without the need to generate fresh encryption keys."

Security in a Distributed Key Management Approach

Abstract:

Cloud computing offers many advantages as flexibility or resource-efficiency and can significantly reduce costs. However, when sensitive medical data is outsourced to a cloud provider, classified records can leak. To protect the patients and application providers from a privacy breach data must be encrypted before it is uploaded. In this work, we present a distributed key management scheme that handles user-specific keys in a single-tenant scenario. The underlying database is encrypted and the secret key is only reconstructed temporarily in memory.

The proposed lecture will present advanced achievements in the field of affective computing towards more enhanced human-computer-interaction interfaces, presenting advanced signal processing techniques and implementations applied to Electroencephalogram (EEG) recordings. In particular, the way emotions are 'reflected' in our brain signals and the way actions (both in explicit and implicit way, e.g., gestures in music) are combined with internal representations in our brain (involving mirror neuron system activation), will be presented and discussed. Moreover, potential implementations of the findings in the field of human assistive technology will be shown, including innovative ways of pain management, bullying identification, and Parkinson’s and Alzheimer's community support.

There are many diagnosis and treatment guidelines for certain conditions, but there are others, especially undifferentiated complaints, the problem of diagnosis is wide open. A team from NorthShore, Case Western Reserve, Carnegie Mellon, Weill Cornell, and Johns Hopkins is working on a joint project to study the diagnostic process in the case of several undifferentiated complaints, including (a) Abdominal Pain, and (b) Dizziness. There are many different approaches to the problem of discovery of good diagnostic pathways from the electronic health record. I will discuss several approaches and show some results from each. The problem of finding optimal pathways -- i.e. courses of action that would minimize time to diagnosis without an unacceptable risk of diagnostic error -- remains elusive, so it would give us something to discuss further.
