Summary: Cognitive affective biases refer to the preference for processing negative or positive information. This study investigated the association between 5-HTT levels, measured using positron emission tomography, and affective biases in healthy individuals. The findings suggest that higher 5-HTT levels are associated with a more negative bias.

Summary: This study aimed to develop a novel method to quantify the uptake of dopamine transporter (DAT) and serotonin transporter (SERT) in different brain regions and improve image quality. A prospective study was conducted using SPECT-CT technology in patients with Parkinsonism. The results showed that SPECT-CT provided more accurate quantification, improved image quality, and enabled absolute quantification of extra-striatal regions.

Summary: This study investigated the potential relationship between human character traits (self-directedness, cooperativeness, and self-transcendence) and serotonergic activity, specifically the availability of serotonin transporter (5-HTT) in certain brain regions. The results showed significant positive correlations between self-directedness and 5-HTT availability in specific brain regions, suggesting that a goal-oriented, self-confident, and resourceful character may be related to higher serotonergic neurotransmission. In addition, cooperativeness was significantly negatively correlated with 5-HTT availability in the median raphe nucleus, and self-transcendence was significantly negatively correlated with 5-HTT availability in the right MTG and ITG.

Summary: The purpose of this study was to determine if the image acquisition time for the salivagram can be shortened without significantly reducing the sensitivity in detecting aspiration. It was found that evidence of aspiration could be detected within the first 40 minutes of dynamic imaging, therefore the originally described 60-minute protocol can be safely shortened to 40 or even 30 minutes.

Summary: Idiopathic pulmonary fibrosis (IPF) is a progressive fibrosing interstitial pneumonia that results in declining lung function and quality of life. This study compares the pulmonary vessel-like volume (PVV) in IPF patients with healthy individuals aged over 50, and shows that IPF patients have 2-3 times higher PVV despite relatively low fibrosis extent. The findings suggest that a standardized PVV calculation method considering tree connectivity could be a promising tool for early diagnosis or prognosis in IPF and other interstitial lung diseases.

Summary: This study evaluated the clinical efficacy and safety of botulinum toxin (BTX) injection for chronic parotitis, showing initial improvement in symptoms at 1 month post-injection, but a slight increase at 6 months. However, all subjective symptoms were determined to be better than before injection at the 6-month mark.

Summary: MRI-derived brain measures have been widely studied in bipolar disorder (BD) and provide insights into the connections between genes, the environment, and behavior. The ENIGMA Bipolar Disorder Working Group is a collaborative effort that aims to generate consensus findings and improve the replicability of studies on BD. Through large-scale neuroimaging studies, the working group has discovered patterns of brain alterations associated with BD, as well as the effects of medications and clinical risk profiles.

Summary: Brain imaging techniques allow visualization of SERT occupancy with antidepressant dose. Studies show a hyperbolic relationship between dose and occupancy, plateauing around 80% at minimum recommended dose. Limitations include fragmented data, small sample sizes, and short study durations. Future research should standardize methods and investigate lower dose occupancy.

Summary: The study found that cognitive reactivity (CR) and mindfulness were associated with relapse in remitted major depressive disorder (MDD) patients before the initiation of Mindfulness-based cognitive therapy (MBCT). Higher CR and lower mindfulness were found to increase the risk of relapse, while self-compassion and rumination were not associated with relapse. Particularly, for rumination, there was a significant interaction with the use of maintenance antidepressant medication, impacting its relationship with relapse.

Summary: Defining reference models for population variation and studying individual deviations is crucial for understanding inter-individual variability and its relation to medical conditions. This study constructed a reference cohort of neuroimaging data and used normative modeling to analyze the lifespan trajectories of cortical thickness and subcortical volume. The models were validated and applied to a psychiatric sample, demonstrating their clinical value.

Summary: This study aimed to determine the prevalence of and risk factors for treatment dropout in a large outpatient sample. The analysis of data from 2235 outpatients with MDD revealed that 14.5% of patients dropped out of treatment. Results showed that higher scores on the Measure for Quantification of Treatment Resistance in Depression were associated with lower dropout odds.

Summary: This study provides the first indication that polyunsaturated fatty acids (PUFAs) are associated with the efficacy of electroconvulsive therapy (ECT). The results suggest that PUFAs may affect ECT outcomes by influencing neuronal electrochemical properties and neurogenesis. PUFAs could potentially serve as a modifiable factor predicting ECT outcomes and further investigation is warranted in other ECT cohorts.

Summary: In this study, we extended the normative model repository introduced in Rutherford et al., 2022a to include normative models for lifespan trajectories of structural surface area and brain functional connectivity. We used two resting-state network atlases (Yeo-17 and Smith-10) and an updated online platform to transfer these models to new data sources. Through benchmarking tasks, we demonstrated the value of normative modeling features compared to raw data features, especially in group difference testing and classification tasks. These accessible resources are intended to promote the broader adoption of normative modeling in the neuroimaging community.

Summary: 《Dynamic Changes in Brain Network Connectivity during Recurrence of Major Depressive Disorder》This study investigated the dynamic changes in brain connectivity during the transition from remission to recurrence in major depressive disorder (MDD) patients. The findings showed that during recurrence, there was increased activity in the basal ganglia-anterior cingulate cortex and visuo-attentional networks, as well as a longer duration of activation in the default mode network. Additionally, the synchrony between the reward network and the rest of the brain was significantly reduced during recurrence. These results provide initial evidence of altered dynamical exploration of functional networks during a recurrent depressive episode.

Summary: This study found that patients with major depressive disorder (MDD) have altered reward circuit connectivity during reward anticipation and delivery. The differences were mainly observed in MDD patients who were using antidepressants. This finding expands on existing literature and may contribute to diagnostic and therapeutic efforts for depression-related reward dysfunctions.
