Summary: The study found significant differences in cerebello-cortical functional connectivity between PD patients and normal controls, particularly in the somatomotor network. Cognitive function was found to be associated with connectivity of the cerebellar SMN and dorsal attention network. Altered cerebellar connectivity with frontoparietal and default mode networks was also correlated with the severity of motor function in PD.

Summary: In this study, different sub-phenotypes of Parkinson's disease (PD) were identified based on electrophysiological profiles obtained from resting-state electroencephalography (RS-EEG). These sub-phenotypes showed distinct disruptions in various brain networks and were predictive of disease outcome. EEG features were also able to predict cognitive evolution of PD patients. The identification of these novel PD subtypes based on electrical brain activity signatures has important clinical implications and can support the development of brain-based therapeutic strategies.

Summary: This study aimed to investigate changes in the inherent connectivity pattern of global functional networks in Parkinson's disease (PD) patients with fatigue. Voxel-wise degree centrality (DC) and seed-based functional connectivity (FC) analysis were conducted on 18 PD patients with fatigue (PD-F), 20 PD patients without fatigue (PD-NF), and 23 healthy controls (HCs). The results showed that PD-F patients had reduced DC values in the left postcentral gyrus and increased DC values in the bilateral precuneus. Altered FC was predominantly located in the sensorimotor network in the PD-F group. Cortical thickness did not differ significantly between the three groups.

Summary: This study proposes a temporal dynamics learning (TDL) method for network-based brain disease identification using rs-fMRI time-series data. By integrating network feature extraction and classifier training into a unified framework, it addresses the issues of previous studies paying less attention to the evolution of global network structures over time and treating feature extraction and training as separate tasks.

Summary: The reliability and robustness of rs-fcMRI depend on minimizing the influence of head motion on brain signals. This study examined the impact of head motion on newborn brain connectivity using a large dataset. The findings revealed that head motion significantly affected connectivity, with specific effects observed in sensory-related and default mode networks. Implementing a motion correction strategy helped reduce the confounding effects of head motion on neonatal rs-fcMRI.

Summary: Around 50% of stroke patients have deficits in proprioception, but our understanding of the neurological mechanisms behind these deficits is limited. This study used resting-state functional magnetic resonance imaging (fMRI) to investigate changes in functional brain networks associated with proprioception deficits in stroke patients. The results showed reduced connectivity in specific brain regions, including the supplementary motor area and the supramarginal gyrus, in stroke patients compared to healthy controls. Functional connectivity of these regions, as well as the primary somatosensory cortex and the parietal opercular area, was significantly associated with proprioceptive function. The parietal lobe of the lesioned hemisphere was identified as an important node for proprioception after stroke, and evaluating the functional connectivity of this region could help predict recovery. The study also identified potential targets for therapeutic neurostimulation to aid in stroke recovery.

Summary: This study investigated the pathological interaction of sensory and cognitive function in schizophrenia and its relationship to system-level imbalance. The results revealed a compression of the cortical hierarchy organization, leading to a diminished separation between sensory and cognitive systems. Furthermore, the analysis showed reduced connectivity within unimodal regions and increased connectivity between unimodal regions and other areas. These findings suggest that disruptions in the somatosensory-motor system and inefficient integration of sensory information contribute to high-level cognitive deficits in schizophrenia.

Summary: This study used T1-weighted and T2-weighted MRI to investigate the myelination changes in temporal lobe epilepsy (TLE) patients. The mSCN analysis showed decreased myelination in frontotemporal regions, amygdala, and thalamus in both patient groups compared to healthy controls. Left TLE patients also had lower myelination in left medial temporal regions. The findings suggest that myelination alterations in TLE are related to epileptic seizures.

Summary: This study investigated the expression and prognostic significance of ITGB2 in glioma. The results showed that ITGB2 can be a potential marker for mesenchymal molecular subtype gliomas and an independent predictive marker of overall survival in malignant glioma patients. In addition, ITGB2 is closely related to glioma immune-related activities. Methylation of ITGB2 negatively regulates its expression in low-grade glioma tissues and can be used to predict the overall survival of low-grade glioma patients.

Summary: In this study, an AI-assisted multistrategy image enhancement technique was developed to improve the accuracy of COVID-19 classification on chest X-ray (CXR) images. The new strategy consisted of three parts: segmentation, bone signal suppression, and super-resolution reconstruction. Comparative experiments showed that the multistrategy enhanced CXR images had better performance in terms of peak signal-to-noise ratio and root mean square error. The classification accuracy of COVID-19 was improved using the improved CXR images.

Summary: This study investigates the spatiotemporal dynamics of schizophrenia and its relationship with psychiatric symptoms. A total of 98 patients with schizophrenia underwent resting-state functional magnetic resonance imaging, and the variations in functional connectivity density were evaluated. The findings show that patients exhibit altered temporal and spatial variations in different brain networks, and the variations in perceptual and attentional systems are associated with symptom severity. Moreover, the differences between patients and healthy subjects are related to the densities of dopamine, serotonin and mu-opioid receptors, as well as the densities of serotonin reuptake transporter, dopamine transporter, and dopamine synthesis capacity. Overall, this study highlights the importance of brain dynamics in understanding the pathological mechanism of schizophrenia.

Summary: In this study, the features of theta oscillations and the functional interactions among activation/deactivation networks during the n-back working memory (WM) task were examined in patients with idiopathic generalized epilepsy (IGE) using simultaneous EEG-fMRI. The results showed enhanced frontal theta power and increased activations in high-load WM tasks in IGE patients, as well as decreased counteraction between the activation network and deactivation network. These findings suggest the important role of the interactions between activation and deactivation networks in WM processing and provide insights into the pathophysiological mechanism of cognitive dysfunction in generalized epilepsy.

Summary: Anti-PD-1 therapy shows effective outcomes in both liver cancer patients and non-liver cancer patients infected with HBV. Through a retrospective multicenter study, it is found that HBV+ non-liver cancer patients have better responses to anti-PD-1 therapy compared to HBV- non-liver cancer patients. Additionally, in HBV+ ESCC patients, the cytotoxicity score of T cells and MHC score of B cells significantly increase after anti-PD-1 therapy. CX3CR1(high) T-EFF, a subset of CD8(+) T-EFF, is also associated with better clinical outcomes in HBV+ ESCC patients.

Summary: This study identified shared genetic signatures and immune microenvironment between multiple sclerosis (MS) and non-small cell lung cancer (NSCLC) and revealed the molecular mechanisms underlying their relationship. Phosphodiesterase 4A (PDE4A) was identified as the most significant shared gene, and its high expression was associated with poor prognosis in NSCLC patients. Therefore, PDE4A may serve as a potential therapeutic target and immune-related biomarker for patients with both MS and NSCLC.

Summary: The purpose of this study was to assess the optimal characteristics of monoenergetic image (MEI (+)) from dual-energy CT (DECT) and its diagnostic performance for T staging in patients with thoracic esophageal cancer (EC). The results showed that MEI (+) at 40 keV in the venous phase had the best tumor delineation. The MEI (+) images had significantly higher signal-to-noise ratio (SNR) and tumor contrast-to-noise ratio (CNR) compared to the polyenergetic image (PEI). The agreement between MEI (+) (40 keV) and pathological T categories reached 81.63%.
