Article Synopsis
  • Skin cancer diagnosis relies heavily on image quality, particularly the impact of HDR-enhanced images, on clinicians' and AI models' accuracy.
  • A study with 18 dermatology clinicians assessed 303 skin lesion images classified into low, high, and enhanced quality, finding the best diagnostic performance with high-quality images.
  • While clinicians outperformed a CNN model in diagnosing low and enhanced quality images, the CNN excelled in multiclass classification with high-quality images, showing the varying effectiveness of image quality in diagnostics.

Sociotechnical imaginaries of gene editing in food and agriculture reflect and shape culturally particular understandings of what role technology should play in an ideal agrifood future. This study employs a comparative media content analysis to identify sociotechnical imaginaries of agricultural gene editing and the actors who perform them in five countries with contrasting regulatory and cultural contexts: Canada, Japan, New Zealand, the Netherlands, and the United States. We find that news media in these countries reinforce a predominantly positive portrayal of the technology's future, although variations in which imaginaries are most mobilized exist based on the regulatory status of gene editing and unique histories of civil society engagement around biotechnology in each country.

Objective: Fat embolism syndrome and cerebral fat emboli are rare yet serious conditions arising from systemic distribution of bone marrow emboli. Emboli are known to produce high-intensity transient signals (HITS) in a Doppler signal. We hypothesized that both intramedullary nailing in pigs and median sternotomy in human infants cause bone marrow release, that some of these cause cerebral emboli, and that these were detectable by a new cerebral doppler ultrasound monitoring system (NeoDoppler).

Background: Electrogram dispersion identifies putative atrial fibrillation (AF) drivers in first time ablation procedures, with high acute termination rates and long-term outcomes akin to extensive ablation approaches. Its use in a population that had undergone repeat ablation is unknown, particularly where the pulmonary veins are already isolated.

Objective: This purpose of this study was to assess electrogram dispersion mapping during repeat ablation procedures for persistent AF.

Objective: The objective of this review was to identify and synthesize the best available evidence on how adult patients experience living with depression-related insomnia, and their experiences related to pharmacological and non-pharmacological interventions aimed at improving sleep.

Introduction: Insomnia affects 80% to 90% of patients with depression. The costs of insomnia are considerable for the individual and society alike.
