Summary: This study quantitatively assessed the accuracy of a commercially available deformable image registration (DIR) algorithm in generating prostate contours, showing high consistency between auto-generated and manually drawn contours, as well as good robustness of radiomic features to differing contours. The majority of DIRs were within recommended tolerance, indicating promising potential for auto contour usage in radiomic feature analysis.

Summary: The emerging field of radiomics aims to reveal hidden information in standard-of-care images by transforming them into quantifiable statistical data. This study proposes a novel pipeline that uses the Wasserstein metric to deal with spatial texture features in radiomic studies and incorporates them into a supervised image classification pipeline using support vector machine algorithm and Bayesian optimization. The proposed technique shows great potential in classifying COVID-19 CT images and provides MATLAB code for further use.

Summary: Emerging evidence suggests that activity flow over resting-state network topology can predict task activations. In this study, the authors propose a probabilistic functional connectivity (FC) estimation derived from a dynamic framework as a new activity flow route. They test the activity flow mapping using between- and within-network connections and tight task contrasts. The results show that probabilistic FC routes substantially improve individual-level activity flow prediction, particularly in higher-order cognitive control systems. The study also demonstrates divergent influences of connectional topology and task contrasts on activity flow prediction across brain systems with different functional hierarchies.

Summary: This study investigates the ability of MRI radiomic features to discriminate different image textures under different volumes of analysis regions. The results indicate that a too-small volume can impair the discriminative ability of radiomic features. Additionally, the study proposes a methodology that can be applied to other imaging modalities and clinical scenarios. This is important for the design of MRI radiomic studies and the extraction of quantitative biomarkers for clinical diagnosis and treatment.

Summary: Despite good agreement for most radiomic features across different software programs, there is relatively poor agreement for morphology features. Significant differences were also found in programs that use different gray-level discretization approaches. The inconsistency in evaluating morphological features among software programs highlights the need for further studies to standardize radiomic feature extraction workflows.

Summary: This study examines the feasibility of using radiomics for differentiating between the three most common malignant brain tumor types with varying MRI sequence combinations. The results show that T1 contrast enhanced MRI sequence performs comparably to multiparametric MRI, and model performance is influenced by tumor subregions and the chosen model/feature selection methods.

Summary: A model-free approach is proposed to detect changes in BOLD signals in white matter (WM) by measuring task-evoked increases of BOLD signal synchrony in WM fibers. The results demonstrate that neural activity can be reliably detected as increases in fMRI signal synchrony within WM fibers that are engaged in a task with high sensitivities and reproducibility.

Summary: Integrative tumor characterization linking radiomic profiles to gene expression in endometrial cancer patients was explored in this study. A high RPI based on MRI was associated with poor survival outcomes and revealed significant transcriptional alterations. Key genes such as COMP and DMBT1 were identified as potential prognostic markers in this context.

Summary: This study investigated the use of radiomics models derived from enhanced MRI images to predict Ki-67 expression in hepatocellular carcinoma. The arterial phase radiomics model showed better predictive performance, with the combined model including AP Rad-score and serum AFP levels improving the predictive accuracy further. The findings suggest that a combined model based on enhanced MRI can accurately predict Ki-67 expression in HCC preoperatively.

Summary: The current treatment strategy for pilonidal sinus disease (PSD) in Germany mainly consists of primary excision and open wound healing. However, the use of flap procedures and off-midline techniques has increased over the past 20 years. Despite this increase, minimally invasive approaches are still underutilized. Compliance with national guidelines for PSD treatment remains poor.

Summary: This study aimed to predict survival outcomes in peritonitis patients treated with open abdomen surgery using a multidomain prediction model. The results indicated that the surgical predictor skin closure, along with the physiological predictors SAPS-II and MPI, were key factors in predicting survival. The integrative prediction model outperformed individual predictors in predicting survival outcomes.

Summary: The purpose of this study is to provide guidelines for clinicians on treating patients with brain metastases from solid tumors. The study conducted a systematic review of the literature and found that surgery is a reasonable option for patients with brain metastases. Local therapy should be given to patients with symptomatic brain metastases, regardless of the systemic therapy used. For patients with asymptomatic brain metastases, local therapy should not be deferred unless specifically recommended. Several regimens were recommended for different types of cancer. For patients with no systemic therapy options, stereotactic radiosurgery (SRS) alone should be offered. Memantine and hippocampal avoidance should be considered for patients receiving whole brain radiation therapy. Patients with low Karnofsky Performance Status and no systemic therapy options do not benefit from radiation therapy.

Summary: This is the first modern surgical series providing long term follow-up for patients undergoing surgical resection of pineal region tumors. Obtaining a gross total resection of these challenging tumors is beneficial for improving progression free survival and overall survival. Higher grade tumors have decreased survival rates and are often treated with adjuvant chemotherapy and/or radiotherapy.

Summary: Postcraniotomy headache (PCH) is a common and underappreciated adverse event. The use of opioids for pain relief may interfere with neurologic evaluation and should be minimized. Special attention should be given to pain control for both acute and chronic PCH, particularly in neurosurgical settings.

Summary: Endothelial progenitor cells (EPC) have the potential to influence the integrity and stability of the vascular endothelium, but their role and applicability as biomarkers in clinical settings are still uncertain. Evaluating endothelial dysfunction remains a major challenge, largely due to the heterogeneity of this cell population. To use EPC levels as biomarkers for vascular function and cardiovascular risk, defining their phenotype accurately and updating current isolation methods are urgent priorities.

Summary: Surgical evacuation of chronic subdural hematoma (SDH) is often contraindicated in cancer patients with refractory thrombocytopenia. Middle meningeal artery embolization (MMAE) has emerged as a potential alternative for these patients. This study evaluates the safety and efficacy of MMAE for chronic SDH in cancer patients with refractory thrombocytopenia.
