Objectives: It has been shown that monitoring temporary threshold shift (TTS) after exposure to noise may have a predictive value for susceptibility of developing permanent noise-induced hearing loss. The aim of this study is to present the assumptions of the TTS predictive model after its verification in normal hearing subjects along with demonst...

Background Hearing loss (HL) affects 466 million people of all ages worldwide, with a rapidly increasing prevalence, and therefore requires appropriate public health policies. Multi-disciplinary approaches that make use of eHealth services can build the evidence to influence public policy. The European Union-funded project EVOTION developed a platf...

Abstract Language, socio-emotional and cognitive development in children and adolescents with mental health issues is getting increased attention over the last years. Establishing communication patterns and addressing behavioural diversities among this population should be of priority, along with a better understanding in a large variety of patient...

As the financial cost of electronics is constantly decreasing and new electronic modules are being introduced to the market, the development of many healthcare applications becomes easier, cheaper and more prospects are created for various healthcare related fields. Some of these fields are the pre-hospital care and the telemedicine, which have a l...

General Systems Theory (GST), as it was introduced by Karl Ludwig von Bertalannfy, had a significant, yet mostly unacknowledged influence on systems theory. The purpose of the current review is to highlight and assess the application of the aforementioned theory in the healthcare field and suggest a new approach to the public hearing healthcare sec...

Purpose The EU-funded research project EVOTION has brought together clinical, technical, and public health experts with the aim to offer a solution for the holistic management of hearing loss. This report presents the challenges, strengths, and key take-home messages of working in this multidisciplinary consortium. Method Fifteen consortium members...

The main objective of the article is to employ cloud computing technology in order to develop the decision support system of an integrated platform aimed to aid decision makers in natural disaster incidents. This specific platform refers to the most commonly occurred natural disasters in Europe. The decision support system included in the cloud-bas...

Purpose: The scarcity of health care resources calls for their rational allocation, including within hearing health care. Policies define the course of action to reach specific goals such as optimal hearing health. The process of policy making can be divided into 4 steps: (a) problem identification and issue recognition, (b) policy formulation, (c...

Hearing loss is a huge and increasing global problem; public health methods are needed to address hearing loss on a large scale within countries. For this purpose, good public health policy decisions are essential in order to develop and implement cost-effective programmes. WHO has recently urged Countries to “improve data on ear diseases and heari...

The evaluation and control algorithms for the necessity of medical prescription testing, comprises useful tool for health professionals. It is beyond doubt that a connection between illness, symptoms, medical tests and prescriptions is essential and thus algorithms facilitating such approaches should be available to health professionals. Such infor...

The concept of Information, is probably one of the most difficult physical (or maybe not) quantities to be comprehended. This is true not only due to the definition and physical meaning of Information, but also due to the difficulty in quantifying Information. It has been an intense field of study, especially in the 20th century, due to the revolut...

Given the great potential of mHealth applications as far as chronic diseases management is concerned, we investigated the level of intervention provided by mobile applications for the case of diabetes. Online stores (Google Play Store, App Store, Windows Phone Store) and mHealth-related databases were used as our investigation field and application...

Infrasonic waves, or simply infrasound, are sound waves with frequencies lower than 20Hz, which are not audible to humans. Although there are many sources of infrasound in the environment, either natural or man-made, whose related research is ongoing for many years, a strong concern has emerged over the last decade about whether infrasound poses a...

As Decision Support Systems start to play a significant role in decision making, especially in the field of public-health policy making, we present an initial attempt to formulate such a system in the concept of public health policy making for hearing loss related problems. Justification for the system's conceptual architecture and its key function...

The ageing process of EU population has played a key role raising the prevalence of chronic disease, with more than 80% of people in the last age group (65-74) reported to be having three or more long-term Multimorbidity or Multiple Chronic Conditions (MCCs). The main problem is that currently, clinicians have limited guidance, as well as evidence...

The current paper summarises the research investigating associations between physiological data and hearing performance. An overview of state-of-the-art research and literature is given as well as promising directions for associations between physiological data and data regarding hearing loss and hearing performance. The physiological parameters in...

Human neoplasms are considered to be diseases whose pathogenesis is attributed to genomic aberrations. Yet, it has been previously reported that genomic stability is probably not the sole “player” in tumor ontogenesis. Several genes have been identified that are considerd to be the “oncogenic drivers”. In that sense the present work manifests a hyp...

A Finite Element Model (FEM) of middle ear was used to simulate the pathology of otosclerosis (OS) and tympanosclerosis (TS). Several aspects regarding the two diseases were examined, the results of which are hereby presented, connecting OS and TS with significant hearing loss, depending on the position of the OS and TS plaque accordingly.

The present work aims to develop a fundamentally novel computational model for reconstructing complex software systems, following some massive internal failure or external infrastructure damage. The present model mimics the biological process of information transmission in terms of transcription and subsequent translation, introducing novel terms s...

According to W.H.O., 360 million people worldwide have disabling hearing loss [1]. However, a number of patients are afraid to consider hearing loss a problem and subsequently are afraid to seek medical help for the hearing loss. This may potentially lead hearing impaired individuals to a further level of disability and handicap. [2] In the concept...
