COVID-Twitter-BERT: A natural language processing model to analyse COVID-19 content on Twitter.

Introduction: This study presents COVID-Twitter-BERT (CT-BERT), a transformer-based model that is pre-trained on a large corpus of COVID-19 related Twitter messages. CT-BERT is specifically designed to be used on COVID-19 content, particularly from social media, and can be utilized for various natural language processing tasks such as classification, question-answering, and chatbots. This paper aims to evaluate the performance of CT-BERT on different classification datasets and compare it with BERT-LARGE, its base model.

Categorizing Vaccine Confidence With a Transformer-Based Machine Learning Model: Analysis of Nuances of Vaccine Sentiment in Twitter Discourse.

Background: Social media has become an established platform for individuals to discuss and debate various subjects, including vaccination. With growing conversations on the web and less than desired maternal vaccination uptake rates, these conversations could provide useful insights to inform future interventions. However, owing to the volume of web-based posts, manual annotation and analysis are difficult and time consuming.

"Vaccines for pregnant women…?! Absurd" - Mapping maternal vaccination discourse and stance on social media over six months.

Objective: To understand the predominant topics of discussion, stance and associated language used on social media platforms relating to maternal vaccines in 15 countries over a six-month period.

Background: In 2019, the World Health Organisation prioritised vaccine hesitancy as a top ten global health threat and recognized the role of viral misinformation on social media as propagating vaccine hesitancy. Maternal vaccination offers the potential to improve maternal and child health, and to reduce the risk of severe morbidity and mortality in pregnancy.

Differences in Emotional and Pain-Related Language in Tweets About Dentists and Medical Doctors: Text Analysis of Twitter Content.

Background: Social media provides people with easy ways to communicate their attitudes and feelings to a wide audience. Many people, unfortunately, have negative associations and feelings about dental treatment due to former painful experiences. Previous research indicates that there might be a pervasive and negative occupational stereotype related to dentists and that this stereotype is expressed in many different venues, including movies and literature.

Controversial Ebola vaccine trials in Ghana: a thematic analysis of critiques and rebuttals in digital news.

Background: Communication is of paramount importance in responding to health crises. We studied the media messages put forth by different stakeholders in two Ebola vaccine trials that became controversial in Ghana.

A Proposed Framework to Enrich Norwegian EHR System with Health-trusted Information for Patients and Professionals.

In the era of social media, semantic web and big data, a huge amount of health-related information, knowledge and resources exist on the Web. Patients and healthcare professionals should spend enormous effort and time in order to find health-trusted information, while the appropriate technologies to interlink and retrieve this type of information already exist. In this paper we propose a framework to enrich DIPS, the most deployed Norwegian EHR System, with health-trusted information for patients and state-of-the-art resources for healthcare professionals.

Media preferences in scenarios involving relationship closeness and information valence: evidence of strategic self-presentation and sex differences.

The study investigated strategic self-presentation (relationship closeness, information valence, and sex) on hypothetical choice of media used. 145 participants (73 women, 72 men; M age = 22.3 yr.

Health information accessed on the internet: the development in 5 European countries.

The aim of this study was to summarize and analyse findings from four prior studies on the use of the Internet as a source of health information in five European countries (Norway, Denmark, Germany, Greece, and Portugal). A cross-study comparison of data was performed. All the studies included fit with a trend of a sharp and continuous growth in the use of the Internet for health information access in the major part of the last decade.

Using noninferiority tests to evaluate telemedicine and e-health services: systematic review.

Background: An increasing number of studies within the field of telemedicine and e-health are designed as noninferiority studies, aiming to show that the telemedicine/e-health solution is not inferior to the traditional way of treating patients.

Objective: The objective is to review and sum up the status of noninferiority studies within this field, describing advantages and pitfalls of this approach.

Methods: PubMed was searched according to defined criteria, and 16 relevant articles were identified from the period 2008-June 2011.

Physician response time when communicating with patients over the Internet.

Background: Patients want to use electronic communication to access health services more easily. Health authorities in several countries see this as a way to improve health care. Physicians appear to have conflicting opinions regarding the suitability of electronic communication in clinical settings.

Online communication between doctors and patients in Europe: status and perspectives.

Background: Use of the Internet for health purposes is steadily increasing in Europe, while the eHealth market is still a niche. Online communication between doctor and patient is one aspect of eHealth with potentially great impact on the use of health systems, patient-doctor roles and relations and individuals' health. Monitoring and understanding practices, trends, and expectations in this area is important, as it may bring invaluable knowledge to all stakeholders, in the Health 2.

eHealth trends in Europe 2005-2007: a population-based survey.

Background: In the last decade, the number of Internet users worldwide has dramatically increased. People are using the Internet for various health-related purposes. It is important to monitor such use as it may have an impact on the individual's health and behavior, patient-practitioner roles, and on general health care provision.

Communicating textual health information to the mobile phones of visually-impaired users.

We investigated how short messages communicating health information would best be distributed to people with vision difficulties using mobile phones. Twelve visually-impaired persons who were unable to read short message service (SMS) messages directly compared three methods of presenting text messages as speech: (1) ordinary SMS messages were sent to the users and converted into speech by the mobile phone; (2) multimedia messages were sent to the users with prerecorded speech-synthesized information; and (3) mobile phone calls were placed to the users and prerecorded speech-synthesized messages were streamed to them. The latter two approaches used server-generated sound files.

Patients who use e-mediated communication with their doctor: new constructions of trust in the patient-doctor relationship.

The introduction of information and communication technology (ICT) into the patient-doctor relationship represents a significant change in modern health care. Communication via computers-e-mediated communication-is affecting the context of patient-doctor interaction, touching core elements of the relationship. Based on data from a qualitative study conducted among Norwegian patients who had used ICT to communicate with their doctors, the authors argue that patients' use of ICT and the element of trust in the patient-doctor relationship influence each other.

Electronic patient-provider communication: will it offset office visits and telephone consultations in primary care?

Background And Aim: Electronic patient-provider communication promises to improve efficiency and effectiveness of clinical care. This study aims to explore whether a secure web-based messaging system is an effective way of providing patient care in general practices.

Method: We conducted a randomised controlled trail and recruited 200 patients from the waiting area in one primary clinic in Norway.

"Is Cybermedicine Killing You?"--The story of a Cochrane disaster.

This editorial briefly reviews the series of unfortunate events that led to the publication, dissemination, and eventual retraction of a flawed Cochrane systematic review on interactive health communication applications (IHCAs), which was widely reported in the media with headlines such as "Internet Makes Us Sick," "Knowledge May Be Hazardous to Web Consumers' Health," "Too Much Advice Can Be Bad for Your Health," "Click to Get Sick?," and even "Is Cybermedicine Killing You?". While the media attention helped to speed up the identification of errors, leading to a retraction of the review after only 13 days, a paper published in this issue of JMIR by Rada shows that the retraction, in contrast to the original review, remained largely unnoticed by the public. We discuss the three flaws of the review, which include (1) data extraction and coding errors, (2) the pooling of heterogeneous studies, and (3) a problematic and ambiguous scope and, possibly, some overlooked studies.

[Patient-physician interaction over the internet].
