Introduction: Research indicates that individuals with generalized anxiety disorder (GAD) may experience deficits in positive affect (PA), and tend to dampen or intentionally suppress PA. Despite the presence of PA-related pathology in GAD, little is known about change in PA during GAD treatment.
Objective: This study examines changes in PA, negative affect (NA) and worry in seven participants during cognitive behavioral therapy (CBT) for GAD.
Method: Intensive repeated measures (i.e., time series) data were subjected to person-specific regression analysis to delineate individual change trajectories.
Results: Significant improvement in worry was observed in all but one participant. Fear and irritability - indices of NA - each improved in 5/7 participants while sadness improved in 4/7 participants (worsening in one). Of all symptom domains, PA had the poorest treatment response: PA improved in only 2/7 participants and actually significantly worsened in 5/7 individuals even as NA and worry improved during therapy.
Conclusion: These findings indicate that treatment gains from traditional CBT for GAD may not generalize to improvements in PA regulation, or even emotional functioning more broadly. This evidence is a call to increase the focus on PA regulation in treatment for GAD; perhaps PA could be a missing piece in our understanding of ways to bolster GAD treatment outcomes.

Maternal Western Diet Programmes Bile Acid Dysregulation and Hepatic Fibrosis in Fetal and Juvenile Macaques.
Liver Int
February 2025
Department of Pediatrics, University of Colorado Anschutz Medical Campus, Aurora, Colorado, USA.
Background And Aims: Maternal obesity increases the risk of the paediatric form of metabolic dysfunction-associated steatotic liver disease (MASLD), affecting up to 30% of youth, but the developmental origins remain poorly understood.
Methods: Using a Japanese macaque model, we investigated the impact of maternal Western-style diet (mWSD) or chow diet followed by postweaning WSD (pwWSD) or chow diet focusing on bile acid (BA) homeostasis and hepatic fibrosis in livers from third-trimester fetuses and 3-year-old juvenile offspring.
Results: Juveniles exposed to mWSD had increased hepatic collagen I/III content and stellate cell activation in portal regions.
Assessment of tree-associated atypical myopathy risk factors in Acer pseudoplatanus (sycamore) seeds and leaves.

Comparative Neuromuscular Diseases Laboratory, Department of Clinical Science and Services, The Royal Veterinary College, London, UK.
Background: Sycamore tree-derived hypoglycin A (HGA) toxin causes atypical myopathy (AM), an acute, equine pasture-associated rhabdomyolysis but incidence fluctuates.
Objectives: Investigate whether tree or environmental factors influence HGA concentration in sycamore material and are associated with AM relative risk.
Study Design: Retrospective and experimental prospective study.
A rare intersection: squamous cell carcinoma of the tonsil and the anti-TIF1 syndrome masquerade.
BMC Rheumatol

Department of Rheumatology, Overton Brooks VA Medical Center, Shreveport, LA, USA.
Background: Dermatomyositis is a chronic inflammatory condition affecting muscles and skin, often associated with an increased risk of cancer. Specific autoantibodies, including anti-TIF1 (Transcription Intermediary Factor 1), have been linked to this risk. We present a case of dermatomyositis in a male patient positive for anti-TIF1 antibodies, subsequently diagnosed with squamous cell carcinoma of the tonsil, a novel association not previously documented.

Background: Obstructive sleep apnea (OSA) is linked to brain alterations, but the specific regions affected and the causal associations between these changes remain unclear.
Methods: We studied 20 pairs of age-, sex-, BMI-, and education- matched OSA patients and healthy controls using multimodal magnetic resonance imaging (MRI) from August 2019 to February 2020. Additionally, large-scale Mendelian randomization analyses were performed using genome-wide association study (GWAS) data on OSA and 3935 brain imaging-derived phenotypes (IDPs), assessed in up to 33,224 individuals between December 2023 and March 2024, to explore potential genetic causality between OSA and alterations in whole brain structure and function.

Digital transformation (DT) has become vital for companies trying to remain competitive in the recent ever-changing technological environment. DT is the integration of digital technologies into all disciplines of business from regular activities to strategic decision making. Risk management planning requires projects to assess possible risks that may negatively or positively affect a DT project.
