Article Synopsis
- Body dysmorphic disorder (BDD) is a serious problem that isn't treated enough, and using online therapy could help people get better access to treatment like cognitive behavioral therapy (CBT).
- In a study with 77 adults using a 12-week guided smartphone program for BDD, they sent a lot of messages to their coaches to get support.
- The researchers found three main ways people interacted with their coaches and discovered that younger users tended to communicate less while older users communicated more, and this affected how well they followed the treatment.
Background: With a rapidly expanding gap between the need for and availability of mental health care, artificial intelligence (AI) presents a promising, scalable solution to mental health assessment and treatment. Given the novelty and inscrutable nature of such systems, exploratory measures aimed at understanding domain knowledge and potential biases of such systems are necessary for ongoing translational development and future deployment in high-stakes healthcare settings.
Methods: We investigated the domain knowledge and demographic bias of a generative, AI model using contrived clinical vignettes with systematically varied demographic features.
Article Synopsis
- Smartpsychotherapy apps are becoming more popular, but we don't know much about how people like to use them or what counts as good engagement.
- A study looked at data from a trial using a phone app to help people with body dysmorphic disorder for 12 weeks, analyzing how people engaged with the app.
- They found three types of users (deep, sampler, and light) and discovered that different ways of using the app can still lead to improvement, especially for deep users.
Background: Modulation of novel cardiorenal and inflammatory markers may provide insight into the disease process and outcomes of patients with acute decompensated heart failure.
Methods And Results: In this open-labeled, prospective, randomized study, 89 patients received either nesiritide (NES) or nitroglycerin (NTG) infusion by standard protocol. The serum or plasma concentrations of cystatin-C and inflammatory markers (high-sensitivity C-reactive protein, tumor necrosis factor-α, transforming growth factor-β1, and interleukin-6) were measured in 66 patients with acute decompensated heart failure at baseline and during drug infusion.
Background: Rises in serum creatinine and efficacy have been reported as dose-related effects of nesiritide and nitroglycerin in acute decompensated heart failure (ADHF). However, no study has evaluated the comparative safety, efficacy, and biomarkers of optimally dosed nesiritide versus nitroglycerin in ADHF.
Methods And Results: Eighty-nine ADHF patients were prospectively randomized to receive either nesiritide (0.
