Background: Targeted therapies have been associated with potential risk of malignancy, which is a common concern in daily rheumatology practice in patients with inflammatory arthritis (IA) and a history of cancer.

Objectives: To perform a systematic literature review to inform a Task Force formulating EULAR points to consider on the initiation of targeted therapies in patients with IA and a history of cancer.

Methods: Specific research questions were defined within the Task Force before formulating the exact research queries with a librarian.

Background: Potential associations between targeted therapies and a new cancer in patients with inflammatory arthritis (IA) and a previous malignancy are a frequent concern in daily rheumatology practice.

Objectives: To develop points to consider (PTC) to assist rheumatologists when initiating a targeted therapy in the context of a previous malignancy.

Methods: Following EULAR standardised operating procedures, a task force met to define the research questions for a systematic literature review and to formulate the overarching principles (OPs) and the PTC.

Ovariohysterectomy (OVH) is a common procedure in bitches, where ovarian suspensory ligament (OSL) rupture facilitates hemostasis but may also have adverse effects. Given the importance of minimizing the surgical stress response, this study aimed to evaluate the impact of OSL rupture in 20 healthy bitches undergoing elective open OVH; a celiotomy via the ventral midline was performed, and hemostasis achieved using bipolar coagulation, either with OSL rupture (OSL-R) or without (OSL-NR). Pain was assessed over 24 h post-surgery using the Visual Analogue Scale and the Short Form of the Glasgow Composite Measure Pain Scale.

Article Synopsis
  • The study investigates how the age-related microRNA miR156 influences the development of extrafloral nectaries (EFNs) in two species of passion flower.
  • Results show that manipulation of miR156 affects both leaf maturation and EFN formation, with overexpression leading to smaller and fewer EFNs, while reduced activity results in larger EFNs in one species.
  • This research highlights a connection between miR156 activity, nectar sugar profiles, and the ecological interactions between EFNs and ants, underscoring the role of the miR156/SPL module in regulating these traits based on leaf age.

Background And Objectives: Early detection of cognitive impairment is crucial for timely clinical interventions aimed at delaying progression to dementia. However, existing screening tools are not ideal for wide population screening. This study explores the potential of combining machine learning, specifically, one-class classification, with simpler and quicker motor-cognitive tasks to improve the early detection of cognitive impairment.
