Department of Neurosurgery, Center for Malignant Brain Tumors, National Glioma MDT Alliance, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, 100730, China.

Brain tumors are associated with a dismal prognosis, and the diagnosis often evokes significant psychological distress. However, the progression of emotional well-being throughout the clinical course of brain tumors remains poorly understood. This study aims to assess the prevalence of anxiety and depression in brain tumor patients and to identify the risk factors associated with postoperative emotional derangement in glioma and metastatic groups seperately.

Radiomics is a method that extracts many features from medical images using various algorithms. Medical nomograms are graphical representations of statistical predictive models that produce a likelihood of a clinical event for a specific individual based on biological and clinical data. The radiomic nomogram was first introduced in 2016 to study the integration of specific radiomic characteristics with clinically significant risk factors for patients with colorectal cancer lymph node metastases.

Ossification of the ligamentum flavum (OLF) is the main causative factor of spinal stenosis, but how to accurately and efficiently identify the ossification region is a clinical pain point and an urgent problem to be solved. Currently, we can only rely on the doctor's subjective experience for identification, with low efficiency and large error. In this study, a deep learning method is introduced for the first time into the diagnosis of ligamentum flavum ossificans, we proposed a lightweight, automatic and efficient method for identifying ossified regions, called CDUNeXt.

Cleft lip and palate anomalies constitute both aesthetic and functional impairments for affected individuals. While an individual with an unrepaired cleft palate may adjust somewhat to the associated feeding challenges as he or she gets older, the consequent speech impairment is amenable primarily to surgery. It is pertinent to assess how well speech function is restored in individuals with cleft after surgical repairs.

Detection of Retinal and Choriocapillaris Microvascular Changes in Retinal Vein Occlusion and Fellow Eyes by Optical Coherence Tomography Angiography: A Systematic Review and Meta-Analysis.

Ophthalmol Ther

December 2024

Department of Ophthalmology, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences, No.1 Shuaifuyuan, Wangfujing, Dongcheng District, Beijing, 100730, China.

Introduction: This study aims to summarize the retinal and choroidal microvascular features detected by optical coherence tomography angiography (OCTA) in the affected and fellow eyes of patients with retinal vein occlusion (RVO).

Methods: A comprehensive search of the PubMed, Embase, and Ovid databases was conducted to identify studies comparing OCTA metrics among RVO, RVO-fellow, and control eyes. Outcomes of interest included parameters related to foveal avascular zone (FAZ) and fovea- and optic nerve head (ONH)-centered perfusion measurements of superficial capillary plexus (SCP), deep capillary plexus (DCP), and choriocapillaris layer.

Employing advanced machine learning models, we aim to identify biomarkers for urolithiasis from 24-h metabolic urinary abnormalities and study their associations with urinary stone diseases. We retrospectively recruited 468 patients at Peking Union Medical College Hospital who were diagnosed with urinary stone disease, including renal, ureteral, and multiple location stones, and had undergone a 24-h urine metabolic evaluation. We applied machine learning methods to identify biomarkers of urolithiasis from the urinary metabolite profiles.

Transcranial Magnetic Stimulation-Electroencephalography (TMS-EEG) is a non-operative technique that allows for magnetic cortical stimulation (TMS) and analysis of the electrical currents generated in the brain (EEG). Despite the regular utilization of both techniques independently, little is known about the potential impact of their combination in neurosurgical practice. This scoping review, conducted following PRISMA guidelines, focused on TMS-EEG in epilepsy, neuro-oncology, and general neurosurgery.

Background: Although cervical cancer (CC) is highly preventable through appropriate screening methods like the Papanicolaou (Pap) test, which enables early detection of malignant and precancerous lesions, access to such screening has not been equitable across social groups. Sex workers and people with records of incarceration are among the most under-screened populations in Ontario. Little is known about the acceptability and feasibility of HPV self-sampling (HPV-SS) as an alternative cervical cancer screening method for these groups.

Context: Lower Urinary Tract Symptoms (LUTS) are defined by their distressing effect on patients' day-to-day life. Given the pressures on secondary care resources, LUTS may be overlooked or inadequately assessed and therefore patients may be burdened for an extended period before treatment.

Methods: In a debate held at the International Consultation on Incontinence Research Society (ICI-RS) meeting in Bristol in June 2024, we considered how new technologies might contribute to an expedited, dignified and effective investigation of LUTS.

Article Synopsis
  • This study used computational fluid dynamics (CFD) to explore how blood flow dynamics in the draining veins of arteriovenous malformations (AVMs) relate to whether they rupture or not.
  • Researchers analyzed data from computed tomography angiography (CTA) and found that while the shape of the veins was similar in ruptured and unruptured cases, ruptured AVMs had significantly higher intravascular pressure and wall shear stress (WSS) in specific vein segments.
  • The findings suggest that ruptured AVMs are associated with higher blood flow velocity and pressure, particularly in the posterior segments of the draining veins, which may help in understanding AVM rupture mechanisms.
