Effects of repetitive transcranial magnetic stimulation (rTMS) on cognitive impairment in depression: A systematic review and meta-analysis.

Objective: Cognitive dysfunction is a core symptom of depression and contributes significantly to functional and psychosocial impairment. However, pharmacotherapy has shown limited efficacy in alleviating these cognitive deficits. This study aimed to systematically evaluate the efficacy of repetitive transcranial magnetic stimulation (rTMS) in improving cognitive impairments in patients with depression.

Aberrant patterns of spontaneous brain activity in schizophrenia: A resting-state fMRI study and classification analysis.

Background: Schizophrenia is a prevalent mental disorder, leading to severe disability. Currently, the absence of objective biomarkers hinders effective diagnosis. This study was conducted to explore the aberrant spontaneous brain activity and investigate the potential of abnormal brain indices as diagnostic biomarkers employing machine learning methods.

Association of anhedonia with brain-derived neurotrophic factor and interleukin-10 in major depressive disorder.

Background: Anhedonia, a core symptom of major depressive disorder (MDD), manifests in two forms: anticipatory and consummatory, reflecting a diminished capacity to anticipate or enjoy pleasurable activities. Prior studies suggest that brain-derived neurotrophic factor (BDNF) and interleukin-10 (IL-10) may play key roles in the emergence of anhedonia in MDD. The specific relationships between these biomarkers and the two forms of anhedonia remain unclear.

Circ_0020123, a New Circular RNA Biomarker for Deep Vein Thrombosis in Pregnant Women.

Background: Deep vein thrombosis (DVT) commonly occurs among vascular diseases globally, for which circular RNAs (circRNAs) are becoming a promising option by mediating functions of human umbilical vein endothelial cells (HUVECs). Therefore, this study focuses on whether circ_0020123 plays a role in HUVECs.

Methods: Pregnant women with DVT (n = 39) and without DVT (n = 39) were selected as the observation group and control group, respectively.

Robustness of VMAT to setup errors in postmastectomy radiotherapy of left-sided breast cancer: Impact of bolus thickness.

Background: Volumetric modulated arc therapy (VMAT) with varied bolus thicknesses has been employed in postmastectomy radiotherapy (PMRT) of breast cancer to improve superficial target coverage. However, impact of bolus thickness on plan robustness remains unclear.

Methods: The study enrolled ten patients with left-sided breast cancer who received radiotherapy using VMAT with 5 mm and 10 mm bolus (VMAT-5B and VMAT-10B).

A practical method to improve the performance of knowledge-based VMAT planning for endometrial and cervical cancer.

Purpose: The aim of this work was to demonstrate a practical and effective method to improve the performance of RapidPlan (RP) model.

Methods: 203 consecutive clinical VMAT plans (P) for cervical and endometrial cancer were used to train an RP model (M). The plans were then reoptimized by M to generate 203 new plans (P).

Temporary pacemaker protected transjugular intrahepatic portosystemic shunt in a patient with acute variceal bleeding and bradyarrhythmia: A case report.

Background: Esophagogastric varices are a common complication of cirrhosis with portal hypertension and endoscopic treatment has been recognized as a primary preventive and therapeutic option for such patients; however, it should be noted that bradyarrhythmia is regarded as one of the contraindications to endoscopic examination. Meanwhile, acute variceal bleeding may result in a high mortality rate in cirrhotic patients with portal hypertension accompanied by bradyarrhythmia. At present, there is an absence of reports concerning the treatment of such group of patients who underwent transjugular intrahepatic portosystemic shunt (TIPS).

Computed Tomography-Based Evaluation of Volume and Position Changes of the Target Region and Organs at Risk During Radiotherapy for Esophageal Cancer: A Pilot Study.

Objective: To analyze changes in volume and position of target regions and organs at risk (OARs) during radiotherapy for esophageal cancer patients.

Methods: Overall, 16 esophageal cancer patients who underwent radiotherapy, including 10 cases of intensity-modulated radiation therapy (IMRT) and six of three-dimensional conformal radiotherapy (3D-CRT), were enrolled. The prescription doses for the planning target volumes (PTVs) were as follows: PTV1, 64 Gy/32 fractions; and PTV2, 46 Gy/23 fractions.

Ga-fibroblast activation protein inhibitor PET/CT on gross tumour volume delineation for radiotherapy planning of oesophageal cancer.

Background And Purpose: To compare Ga-fibroblast activation protein inhibitor (FAPI) and F-FDG PET/CT in imaging locally advanced oesophageal cancer, and evaluate the potential usefulness of Ga-FAPI PET/CT on gross target volume (GTV) delineation aimed at radiotherapy planning for oesophageal cancer as compared with contrast-enhanced CT (CE-CT) and F-FDG PET/CT.

Materials And Methods: Twenty-one patients with newly diagnosed oesophageal cancer who underwent both F-FDG and Ga-FAPI PET/CT scans were selected. GTVs of the primary tumours based on CE-CT (GTV), PET/CT, and CE-CT plus PET/CT were delineated.

Dosimetric superiority of IMRT with jaw tracking technique for whole esophagus and T-shaped field radiotherapy in advanced esophageal cancer.

Purpose: For whole esophagus and T-shaped field radiotherapy using intensity modulated radiotherapy (IMRT) technique in advanced esophageal cancer, lower absorbed doses to lung and heart remains a challenge. The aim of this study was to investigate the dosimetric superiority in IMRT plans with jaw tracking technique for whole esophagus radiotherapy.

Methods And Materials: Thirty-two patients with esophageal cancer were subjected to IMRT treatment plans using Eclipse treatment planning system.

The Effect of Flattening Filter Free on Three-dimensional Conformal Radiation Therapy (3D-CRT), Intensity-Modulated Radiation Therapy (IMRT), and Volumetric Modulated Arc Therapy (VMAT) Plans for Metastatic Brain Tumors from Non-small Cell Lung Cancer.

Flattening filter free (FFF) may affect outcome measures of radiotherapy. The objective of this study is to compare the dosimetric parameters in three types of radiotherapy plans, three-dimensional conformal radiation therapy (3D-CRT), intensity-modulated radiation therapy (IMRT), and volumetric modulated arc therapy (VMAT), with or without the flattening filter (FF), developed for the treatment of metastatic brain tumors from non-small cell lung cancer (NSCLC). From July 2013 to October 2013, 3D-CRT, IMRT, and VMAT treatment plans were designed using 6 MV and 10 MV, with and without FF, for 10 patients with brain metastasis from NSCLC.
