The use of social media for reproductive health advocacy among physicians: a content analysis of tweets by physicians engaged in reproductive health care.

Background: Physician voices on social media are important for health policy advocacy. However, the extent to which physicians use best practices around health communications strategy is unknown.

Methods: We implemented a content analysis of 1373 tweets from 12 physicians who specialize in reproductive health care and participated in a reproductive health-related advocacy training program, to describe their reproductive health advocacy tweets in terms of levels of engagement, tone, framing and target audience.

Approaches to Research Ethics in Health Research on YouTube: Systematic Review.

Background: YouTube has become a popular source of health care information, reaching an estimated 81% of adults in 2021; approximately 35% of adults in the United States have used the internet to self-diagnose a condition. Public health researchers are therefore incorporating YouTube data into their research, but guidelines for best practices around research ethics using social media data, such as YouTube, are unclear.

Objective: This study aims to describe approaches to research ethics for public health research implemented using YouTube data.

Ethical considerations and methodological uses of Facebook data in public health research: A systematic review.

Objective: Since 2016, around seven in 10 adults in the United States (U.S.) actively use Facebook.

Ethical and Methodological Considerations of Twitter Data for Public Health Research: Systematic Review.

Background: Much research is being carried out using publicly available Twitter data in the field of public health, but the types of research questions that these data are being used to answer and the extent to which these projects require ethical oversight are not clear.

Objective: This review describes the current state of public health research using Twitter data in terms of methods and research questions, geographic focus, and ethical considerations including obtaining informed consent from Twitter handlers.

Methods: We implemented a systematic review, following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, of articles published between January 2006 and October 31, 2019, using Twitter data in secondary analyses for public health research, which were found using standardized search criteria on SocINDEX, PsycINFO, and PubMed.

Immune responses of sheep to microdissected parts of Haemonchus contortus.

Adult specimens of Haemonchus contortus were microdissected into four body fragments: oesophagus, cuticle of oesophagus, gut and cuticle with adjacent muscle layer. The antigenicity of these different body fragments was analysed in comparison to total (whole) worm extracts with immunoblotting and ELISA using sera of H. contortus-infected sheep.
