Image Guided Percutaneous Robotic Interventions for Solid Organs.
Tech Vasc Interv Radiol
December 2024
Robotic systems for minimally invasive procedures, particularly in interventional oncology, have advanced significantly, especially for percutaneous interventions guided by CT, Cone-beam CT, and MRI. These systems, which include needle-guiding and needle-driving robots, enhance the precision of procedures like biopsy and tumor ablation. Needle-guiding robots plan and align the needle, while needle-driving robots autonomously advance it, improving needle placement accuracy, enabling out-of-plane insertion, and reducing radiation exposure.

Purpose: A single-center retrospective study was performed to evaluate the safety and efficacy of minimally invasive irreversible electroporation (IRE) to treat metastatic adrenal tumors.
Materials And Methods: This single-center study, approved by the Institutional Review Board, retrospectively analyzed six patients who underwent image-guided percutaneous IRE for adrenal metastases. Pre-procedural imaging included CT, MRI and/or F-FDG PET-CT scans.
A large treatment gap exists for substance use disorders (SUDs) in India. Among other factors, personality vulnerabilities are widely implicated in the initiation and maintenance of SUDs leading to poor outcomes. Available brief interventions do not adequately address this.

Article Synopsis
- This study investigates the effects of specific genetic mutations (FLT3-ITD, NPM1, WT1) on the outcomes of patients with Cytogenetically Normal Acute Myeloid Leukemia (CN-AML), finding notable survival differences based on NPM1 mutation status.
- Out of 150 patients analyzed, 12.6% had WT1 mutations, and relationships were identified between mutation presence and certain clinical factors, like LDH and hemoglobin levels; however, correlations with overall survival were not consistently significant.
- The results indicate that assessing NPM1 and FLT3-ITD mutations at diagnosis can help predict patient prognosis in AML; further research with larger groups could provide deeper insights
Evidence Synthesis for the Development of National Nursing-Sensitive Indicators in Malaysia: A Literature Review and Stakeholder Engagement Approach.
SAGE Open Nurs
October 2024
Introduction: Nursing-sensitive indicators measure and evaluate nursing care quality and its contribution to patient care. The identification of indicators that demonstrate nursing care contribution and the quality of care delivered locally is of paramount importance, and national indicators that demonstrate this are essential. This paper aims to provide an evidence base of nursing-sensitive indicators that can facilitate the conceptualization of local nursing national indicators.
