Background: Cancer control outcomes of lung cancer are hypothesized to be affected by several confounding factors, including tumor heterogeneity and patient history, which have been hypothesized to mitigate the dose delivery effectiveness when treated with radiation therapy. Providing an accurate predictive model to identify patients at risk would enable tailored follow-up strategies during treatment.

Purpose: Our goal is to demonstrate the added prognostic value of including tumor displacement amplitude in a predictive model that combines clinical features and computed tomography (CT) radiomics for 2-year recurrence and survival in non-small-cell lung cancer (NSCLC) patients treated with curative-intent stereotactic body radiation therapy.

Nasogastric tube placement is frequently performed in various medical settings. While generally deemed safe in patients without risk factors, complications may occur due to malposition, justifying the need of systematic confirmation of position with chest radiographs. We present the case of a critically ill male adult patient for whom the tube position was initially deemed very unusual on postinsertion radiographs, prompting further workup which ultimately confirmed an oropharyngeal perforation with a left parapharyngeal, left visceral, retrotracheal, and right retrodiaphragmatic course, and resulting in a recurrent pneumothorax and empyema treated by surgical decortication.

Introduction: NSCLC is the leading cause of cancer-related mortality. Although immune-checkpoint inhibitors (ICIs) have improved survival in patients with advanced NSCLC, treatment resistance remains a challenge. Cryoactivation, a technique inducing cell death by cycles of freezing and thawing, has the potential to augment tumor responses when combined with ICIs.

Article Synopsis
  • Social anxiety disorder (SAD) often occurs alongside first-episode psychosis (FEP), which can worsen cognitive issues; this study investigates whether group cognitive remediation (CR) is more effective than group cognitive-behavioral therapy (CBT) for improving cognition in FEP+SAD patients.
  • Participants with FEP+SAD were divided into two groups, receiving either CR or CBT, and their cognitive performance was measured at various points, showing significant improvement in executive functions and visual memory for those in the CR group.
  • While 44% of participants completed the CR sessions, the study found challenges in engagement and acceptability, suggesting the need for future research to enhance participation in CR programs.

The diagnosis of central nervous system tumours has been transformed in recent years from a microscopic morphology-based process to one dominated by the identification of somatic genetic alterations in tumour cells. This switch requires implementing radically different methods, for which appropriate training and financial resources must be allocated. The Canadian Association of Neuropathologists (CANP) has followed a process based on the scientific literature and consensus to develop recommendations for molecular testing of tumours of the brain and spinal cord, aiming to balance the need for treatment-determinant accurate diagnosis and the current limitations inherent in the transition to a new paradigm.

Article Synopsis
  • Cannabis use is common among individuals with psychotic disorders and can lead to negative outcomes; this study updates previous research on technology-based psychological interventions aimed at reducing cannabis use in this population.
  • The review included 5083 records and found three studies; two quantitative studies indicated that interventions using cognitive behavioral therapy and motivational techniques effectively reduced cannabis use, while one qualitative study explored opinions on these approaches from patients and clinicians.
  • Despite the growth of mobile health solutions, there is a lack of research on internet and app-based interventions for cannabis use in psychosis, highlighting the need for more qualitative studies in developing these technology-based approaches.

Article Synopsis
  • Intrinsic activation MR elastography (iMRE) uses heartbeats to evaluate tissue stiffness in focal liver lesions, aiming to better distinguish between malignant and benign types compared to extrinsic MR elastography (eMRE).
  • In a study with 55 participants, both iMRE and eMRE were performed, revealing that malignant lesions had significantly higher shear stiffness and damping ratio than benign ones, especially observed in measurements at various frequencies.
  • The effectiveness of iMRE and eMRE in differentiating lesions was quantified, with areas under the receiver operating characteristic curves (AUC) indicating strong overall diagnostic performance for both techniques, particularly with iMRE and eMRE's shear stiffness values.
