Article Synopsis
- The study explores the growing use of deep learning algorithms in radiology for diagnostic support, emphasizing the need for Explainable AI (XAI) to enhance transparency and trust among healthcare professionals.
- A user study evaluated two visual XAI techniques (Grad-CAM and LIME) in diagnosing pneumonia and COVID-19 from chest images, achieving high accuracy rates of 90% and 98%, respectively.
- Despite generally positive perceptions of XAI systems, participants showed limited awareness of their practical benefits, with Grad-CAM being favored for coherency and trust, though concerns about its usability in clinical settings were noted.
Background: The TANDEM multicentre, pragmatic, randomised controlled trial evaluated whether a tailored psychological intervention based on a cognitive behavioural approach for people with COPD and symptoms of anxiety and/or depression improved anxiety or depression compared with usual care (control).
Methods: People with COPD and moderate to very severe airways obstruction and Hospital Anxiety and Depression Scale subscale scores indicating mild to moderate anxiety (HADS-A) and/or depression (HADS-D) were randomised 1.25:1 (242 intervention and 181 control).
Fathers' involvement in care and early initiation of cognitive development activities have a positive impact on a child's social-behavioral, cognitive-academic and emotional-psychological development. This research study, conducted in Tamil Nadu in south India (2017-19), employed a Cluster Randomized Trial to test the impact of techno-social innovations in improving the involvement of fathers in child-care on child development outcomes. Qualitative studies were used to inform the trial and provide insights into pathways of change.

Cryptogenic fibrosing alveolitis (CFA) is known to have a poor longterm prognosis, and we compared the 2 conditions through a longitudinal prospective study.
Methods: We previously compared baseline clinical, physiological, and radiological characteristics in 18 RA-ILD patients with 18 case controls with CFA.
