"Expectancy-Mood Neural Dynamics Predict Mechanisms of Short- and Long-Term Antidepressant Placebo Effects".
Biol Psychiatry Cogn Neurosci Neuroimaging

Department of Psychiatry, University of Pittsburgh. Electronic address:
Objective: Acute experimental models of antidepressant placebo effects suggest that expectancies, encoded within the salience network (SN), are reinforced by sensory evidence and mood fluctuations. However, whether these dynamics extend to longer timescales remains unknown. To answer this question, we investigated how SN and default mode network (DMN) functional connectivity during the processing of antidepressant expectancies facilitates the shift from salience attribution to contextual cues in the SN to belief-induced mood responses in the DMN, both acutely and long-term.

Aim: This study investigates the effects of transcranial direct current stimulation (tDCS) on brain network connectivity in individuals with obsessive-compulsive disorder (OCD).
Methods: In a randomized, double-blind, sham-controlled experimental design anodal tDCS (vs. sham) was applied in a total of 43 right-handed patients with OCD, targeting the right pre-supplementary motor area (pre-SMA).
Effectiveness of the User-Centered "Healthcare CEO" App for Patients With Type 1 Diabetes Transitioning From Adolescence to Early Adulthood: Protocol for a Randomized Controlled Trial.

Background: Young patients aged 16 to 25 years with type 1 diabetes (T1D) often encounter challenges related to deteriorating disease control and accelerated complications. Mobile apps have shown promise in enhancing self-care among youth with diabetes. However, inconsistent findings suggest that further evidence is necessary to confirm the effectiveness of app-based interventions.

Introduction: Sports injuries involving bi-articular muscles like the hip flexors, hamstrings, quadriceps, and gastrocnemius significantly affect athletes' performance and quality of life. Comprehensive rehabilitation is crucial for a pain-free return to play (RTP). Over the past 15 years, platelet-rich plasma (PRP) has emerged for its potential in tissue regeneration.

Article Synopsis
- Ongoing efforts aim to enhance glycemic control in type 1 diabetes, focusing on semaglutide as a potential adjunct to automated insulin delivery therapy in adults.
- A randomized, double-blind crossover trial was conducted with 28 participants, where semaglutide or placebo was used, showing a significant increase in the time spent within the target glucose range by an average of 4.8 percentage points.
- No severe complications like diabetic ketoacidosis or hypoglycemia were reported, indicating that semaglutide is a safe and effective option for improving blood sugar levels in this context.
