Article Synopsis
  • Diabetic retinopathy is a major cause of blindness among adults, but AI diagnostic solutions can help early detection and prevention.
  • The review identified key ethical concerns about AI in diagnostics, including patient data protection, bias in algorithms, informed decision-making, and minimizing negative clinical impacts.
  • While AI advancements are promising for reducing blindness, more research is needed on equitable access and safeguards to ensure ethical implementation in healthcare.

Article Synopsis
  • - Research indicates that 12 lifestyle factors could account for up to 40% of dementia cases, but how these factors affect individuals specifically is unclear.
  • - Traditional ethical principles like beneficence and autonomy don't definitively guide whether to share these risk factors with cognitively unimpaired people in research.
  • - The authors propose evaluating the sharing of modifiable risk factors based on how changes in behavior and lifestyle can improve current brain health, rather than just predicting future dementia risk.

The UK government has recently committed to adopting a new policy-dubbed 'Martha's Rule'-which has been characterised as providing patients the right to rapidly access a second clinical opinion in urgent or contested cases. Support for the rule emerged following the death of Martha Mills in 2021, after doctors failed to admit her to intensive care despite concerns raised by her parents. We argue that framing this issue in terms of patient rights is not productive, and should be avoided.

To evaluate the transdermal delivery of six analgesic drugs (i.e., ketamine, gabapentin, clonidine, lidocaine, ketoprofen, and amitriptyline) that were compounded into three commercially available bases, Salt Stable LS Base, Transdermal Pain Base, and Lipoderm ActiveMax Base, the Franz finite dose model was used for an in vitro penetration study using porcine skin over 48 hours.

Objective: Functional neuroimaging may provide a viable means of assessment and communication in patients with Guillain-Barré Syndrome (GBS) mimicking the complete locked-in state. Functional neuroimaging has been used to assess residual cognitive function and has allowed for binary communication with other behaviourally non-responsive patients, such as those diagnosed with unresponsive wakefulness syndrome. We evaluated the potential application of functional neuroimaging using a clinical-grade scanner to determine if individuals with severe GBS retained auditory function, command following, and communication.

A general obligation to make aggregate research results available to participants has been widely supported in the bioethics literature. However, dementia research presents several challenges to this perspective, particularly because of the fear associated with developing dementia. The authors argue that considerations of respect for persons, beneficence, and justice fail to justify an obligation to make aggregate research results available to participants in dementia research.

Neuroimaging research regularly yields "incidental findings": observations of potential clinical significance in healthy volunteers or patients, but which are unrelated to the purpose or variables of the study.

Disorders of consciousness (DOC) continue to profoundly challenge both families and medical professionals. Once a brain-injured patient has been stabilized, questions turn to the prospect of recovery. However, what "recovery" means in the context of patients with prolonged DOC is not always clear.

Patients with severe disorders of consciousness are thought to be unaware of themselves or their environment. However, research suggests that a minority of patients diagnosed as having a disorder of consciousness remain aware. These patients, designated as having "cognitive motor dissociation" (CMD), can demonstrate awareness by imagining specific tasks, which generates brain activity detectable via functional neuroimaging.

Powered by 'big health data' and enormous gains in computing power, artificial intelligence and related technologies are already changing the healthcare landscape. Harnessing the potential of these technologies will necessitate partnerships between health institutions and commercial companies, particularly as it relates to sharing health data. The need for commercial companies to be trustworthy users of data has been argued to be critical to the success of this endeavour.

Background: Social media has an increasingly important role in scientific communication, clinical discussions and knowledge distribution. While several surgical disciplines have taken to internet for increased connectivity, there is currently little knowledge about the social media activity in the field of hepatopancreatobiliary surgery. We aimed to evaluate the implementation and use of a specific HPB hashtag and Twitter handle.

Article Synopsis
  • The study aimed to review existing patient-reported outcome measures (PROMs) for colorectal cancer and inflammatory bowel disease (IBD), while also creating a plan to develop a core outcome set through social media engagement.
  • It involved collaborative input from various stakeholders—including patients, healthcare professionals, and organizations—gathering insights via Twitter, and ultimately presented and discussed five commonly used PROMs in the field.
  • A new general psycho-physical well-being score was proposed, with survey results indicating strong agreement on its importance, demonstrating innovative ways to involve patients in clinical research despite some limitations of this initial exploratory study.

Many are calling for concrete mechanisms of oversight for health research involving artificial intelligence (AI). In response, institutional review boards (IRBs) are being turned to as a familiar model of governance. Here, we examine the IRB model as a form of ethics oversight for health research that uses AI.

Background: Social media may provide a tool, when coupled with a patient-included™ conference, to enhance the engagement among the general public. We describe authors and potential readers of Twitter content surrounding a patient-included™ scientific congress, the International Consortium for Prevention and Infection Control (ICPIC) 2019.

Methods: Retrospective observational analysis of Twitter users posting with the #ICPIC2019 hashtag during the conference.

The COVID-19 pandemic raised considerable challenges to obtain reliable guidance to help occupational health practitioners, workers, and stakeholders building up efficient prevention strategies at the workplace, between the constant increase of publications in the domain, the time required to run high-quality research and systematic reviews, and the urgent need to identify areas for prevention at the workplace. Social Media and Twitter, in particular, have already been used in research and constitute a useful source of information to identify community needs and topics of interest for prevention in the meatpacking industry. In this commentary, we introduce the methods and tools we used to screen relevant posts on Twitter.

A rapidly growing proportion of health research uses 'secondary data': data used for purposes other than those for which it was originally collected. Do researchers using secondary data have an obligation to disclose individual research findings to participants? While the importance of this question has been duly recognised in the context of primary research (ie, where data are collected from participants directly), it remains largely unexamined in the context of research using secondary data. In this paper, we critically examine the arguments for a moral obligation to disclose individual research findings in the context of primary research, to determine if they can be applied to secondary research.

Background: The randomised controlled trial (RCT) design is increasingly common among studies seeking good-quality evidence to advance educational neuroscience, but conducting RCTs in schools is challenging. Fit to Study, one of six such trials funded by the Education Endowment Foundation and Wellcome Trust, tested an intervention to increase vigorous physical activity during PE lessons on maths attainment among pupils aged 12-13. This review of designing and conducting an RCT in 104 schools is intended as a resource on which researchers might draw for future studies.
