<b>Background and aim: </b>Some studies suggest that narrow-band imaging (NBI) can be more accurate at diagnosing gastric intestinal metaplasia dysplasia than white-light endoscopy (WLE) alone. We aimed to assess the real-time diagnostic validity of high resolution with without NBI in diagnosis premalignant conditions derive a classification for endoscopic grading (EGGIM). <b>Methods: </b>A multicenter prospective study (five centers: Portugal, Italy, Romania, UK, USA) was performed...
Mitochondrial DNA (mtDNA), the circular molecule inside mitochondria of all eukaryotic cells, has been shown to be under effect purifying selection in several species. Traditional testing based simply on ratios nonsynonymous synonymous mutations, without considering relative age each mutation, which can determined by phylogenetic analysis this non-recombining molecule. The incorporation a mutation time-ordering from phylogeny and predicted pathogenicity scores for mutations allow...
This work proposes an architecture to treat georeferenced data from the OpenStreetMap plan routes. The methodology considers following steps: collecting data, incorporating into a manager, importing model, executing routing algorithms, and visualizing Our proposal incorporates features characterizing each street segment: safety & security, comfort, accessibility, air quality, time, distance. Routes can be calculated considering any specified weighting system of these features. outcome...
Abstract Background The impact of coexistent IBD and PSC on disease progression prognosis is unclear. This study evaluates outcomes in patients with both conditions, using the novel Risk Estimate Tool (PREsTO) for prognosis. Methods A retrospective multicentric identified IBD-PSC through a national survey. PREsTO was calculated to predict PSC-related liver decompensation, tracked via composite outcome measures. Results Among 77 from six nationwide participating centres, 59 were included,...
Due to an increase in population, urban centers are currently seeing traffic, resulting negative consequences such as pollution and congestion. Efforts have been made promote a modal shift towards the use of more sustainable means transport, walking cycling, but several deterrents influence citizens’ perceptions safety, security comfort, discouraging their choice active modes transport. This study focuses on importance providing meaningful information vulnerable road users (VRUs) support...
Background Aging of the global population is slowly paving way for new markets care products and services. The desire older people to maintain their independence while remaining at home boosting development ambient assisted living (AAL) solutions. Lack user awareness AAL solutions paired with an insufficient use user-centered participatory design approaches in these has hindered uptake by end users. Objective This study aims describe usability users’ experiences within a novel platform,...
This article presents a framework to assist in the design of technology-based interactive services for active mobility, which allows data collected from sensors be made available citizens. The proposed was developed based on focus group sessions held with potential stakeholders and related models frameworks. It consists 8 steps, namely: strategy, scope, structure, skeleton, aesthetics execution. will enable presentation relevant information that help users modes transport decision making...
It has been proved that pharmacovigilance benefits from the analysis and extraction of user generated data blogs, medical forums or other social networks, regarding adverse effect mentions complaints occur taking certain drugs. Data mining, machine learning, pattern recognition, content summarization natural language processing techniques are often used in this field with promising results. However, there still several difficulties concerning extraction, as highly domain-specific vocabulary...
Public transport services play an important role in the mobility of population urban centers, allowing a decrease number private vehicles circulation and contributing to more sustainable mobility. However, emergence COVID-19 pandemic had serious impact on habits population, with substantial reduction public passengers due fear contagion, which raises questions about future sustainability cities. Thus, it is essential restore confidence travelers feel safe comfortable using services. Taking...
Gastric cancer is a serious disease that most people usually do not know they have until start to get symptoms. Gastroenterology imaging an essential tool for this battle, since early diagnosis typically leads good prognosis. However, rapidly evolving technological area with novel devices such as capsule, narrow-band or high-definition endoscopy. Adapting these technologies has high time-price cost, even experienced clinicians, motivating the appearance of interactive environments can...
Nowadays, online route planners for soft modes are provided by several platforms such as Google Maps, OpenStreetMap, Here, or Waze. Itineraries usually built using Shortest Path Problem algorithms that minimize the travel time distance. In this work, we aim to identify and quantify main features influence itineraries’ choice users in urban areas, able support multi-objective routing, simulated scenarios. We propose a set of 21 indicators, grouped into five dimensions: Safety-Security,...
The gastroenterology specialty could benefit from the introduction of Computer Assisted Decision (CAD) systems, since gastric cancer is a serious concern in which an accurate and early diagnosis usually leads to good prognosis. Still, way doctors interact with these systems very important because it will often determine its embracement or rejection, as any gains productivity frequently hinge on how comfortable they are it. Using other types interaction paradigms such voice motion control,...

The rising number of people living in city centers is connected to an increase private vehicles, traffic, and associated harmful effects. Efforts have been made promote a modal shift the use more sustainable transportation means, such as walking cycling, but several factors hinged safety, comfort, accessibility, still hinder this goal. Current route planners often focus on two particular dimensions, time distance, which might not be enough support other personal perceptions. We need consider...
