Single cell combined with laser ablation ICP-MS to study cisplatinum (IV) loaded nanoparticles penetration pathways in osteosarcoma spheroids.

Background: 3D cellular structures have been considered the following step in the evaluation of drugs penetration after 2D cultures since they are more physiologically representative in cancer cell biology. Here the penetration capabilities of Pt (IV)-loaded ultrasmall iron oxide nanoparticles in 143B osteosarcoma multicellular spheroids of different sizes is conducted by a multidimensional quantitative approach. Single cell (SC) and imaging techniques (laser ablation, LA) coupled to inductively coupled plasma-mass spectrometry (ICP-MS) are used to visualize their penetration pathways and distribution in comparison to those of cisplatin.

Searching for variables representing the response to cold stress in mediterranean Geotrupinae reveals an association between heat and cold tolerances.

The study of cold tolerance is imperative for understanding insect activity across spatial and temporal gradients. Here, we assessed various physiological variables to discern the response to cold stress in Mediterranean earth-boring dung beetles, utilizing an infrared thermography protocol initially developed for detecting heat stress variables. Subsequently, we conducted a joint analysis of heat and cold stress variables to explore the extent of congruence between their responses.

Real-World Implementation of Simulation-Free Radiation Therapy (SFRT-1000): A Propensity Score-Matched Analysis of 1000 Consecutive Palliative Courses Delivered in Routine Care.

Purpose: The feasibility of simulation-free radiation therapy (SFRT) has been demonstrated but information regarding its routine care impact and scalability is lacking.

Methods And Materials: In this single-institution, retrospective cohort study, all patients receiving palliative radiation therapy at an Australian tertiary cancer center were eligible for consideration of SFRT unless mask immobilization, a stereotactic technique, or a definitive dose was indicated. Coprimary endpoints were SFRT utilization, impact on consultation-to-RT time, and on-couch treatment duration.

When metabolic comorbidities and risk of malnutrition coexist: The new era of inflammatory bowel disease.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) and risk of malnutrition can coexist in patients with inflammatory bowel disease (IBD). We performed a malnutrition risk assessment as part of the standard follow-up of IBD patients and studied the potential risk factors for being at risk of malnutrition based on the presence or absence of MASLD.

Methods: The Malnutrition Universal Screening Tool (MUST) was used to screen malnutrition risk (MUST ≥1) and controlled attenuation parameter (CAP ≥248 dB/min) to assess MASLD.

Factors associated with electroconvulsive therapy treatment for adults with serious psychiatric conditions in Australia.

Objective: To identify factors associated with receiving electroconvulsive therapy (ECT) for serious psychiatric conditions.

Methods: Retrospective observational study using hospital administrative data linked with death registrations and outpatient mental health data in New South Wales (NSW), Australia. The cohort included patients admitted with a primary psychiatric diagnosis between 2013 and 2022.
