Rhomboid Intercostal and Subserratus Plane Block for Acute Pain Management after Abdominal Surgeries: A Narrative Review.

Purpose Of Review: The rhomboid intercostal and subserratus plane (RISS) block is an effective, safer alternative for managing postoperative acute pain following abdominal surgeries. The RISS block offers several advantages over traditional approaches, including reduced incidence of puncture-related complications, lower rates of systemic opioid consumption, and more consistent analgesic coverage of lower thoracic dermatomes.

Recent Findings: Despite a favorable safety profile, the RISS block carries potential risks, such as pneumothorax and local anesthetic systemic toxicity, particularly when long-acting anesthetics such as bupivacaine or ropivacaine are used.

Basic Science and Pathogenesis.

Background: Tau aggregates, a hallmark of Alzheimer's disease (AD) and other tauopathies, spread throughout the brain, contributing to neurodegeneration. How this propagation occurs remains elusive. Previous research suggests that tau-seed interactors play a crucial role.

Basic Science and Pathogenesis.

Background: Close to 80 to 90% of subjects with AD also present cerebral amyloid angiopathy (CAA) a disease in which amyloid accumulation damages the vasculature an impairs blood flow. Since current AD therapies are targeting the disease focusing on amyloid, we are interested on determine how to decrease the accumulation of amyloid in the vasculature observed in CAA and our aim is to determine the impact of tau reduction in CAA pathogenesis.

Method: We crossed the Tg-FDD mice CAA model with Mapt mice to decrease tau levels and analyzed the disease pathogenesis in the different genotypes though behavioral tests, histological and morphometric assays and transcriptomic analysis using the nCounter neuroimmflamation panel from Nanostring.

Basic Science and Pathogenesis.

Background: Tau aggregation is the major cause of several neurodegenerative tauopathies. Tau interaction with other proteins affects the formation of tau aggregates with seeding activity but less is known about its effects on tau-seed properties. Our previous study revealed that Bassoon (BSN), a presynaptic protein, interacts with tau-seed, exacerbating its toxicity in vivo.
