Abstract INTRODUCTION Neurodegenerative diseases often involve overlapping alpha‐synuclein (asyn), amyloid beta, and tau proteinopathies, yet the mechanisms, impact, and directionality of their interactions remain unclear. METHODS We induced brain‐wide neuronal asyn/tau pathologies via viral expression of wild‐type asyn, mutant asyn E46K , mutant tau A152T , or both asyn E46K /tau A152T in adult amyloidosis knock‐in mice and controls, either post‐plaque deposition (6 months old) or pre‐plaque (3 months old). Open‐field behavior was assessed baseline and 3 and 6 months post‐transduction, followed by neuropathology and neuroinflammation analyses. RESULTS Post‐plaque induction in amyloid mice increased asyn/tau total and phosphorylated levels and exacerbated amyloid‐related hyperlocomotion/anxiety. Pre‐plaque induction produced robust phosphorylated pathologies irrespective of amyloid, while causing similar amyloid‐dependent behavioral synergy. Tau pathology drove LGALS3 + inflammatory glial responses in white‐matter fibers. DISCUSSION Amyloid context gates vulnerability, with certain synergies manifesting across stages. White‐matter gliosis is a novel mechanism of tau A152T risk. Together, our data argue for the development of stage‐aware, multitarget interventions and biomarkers.

Objective: Battlefield acupuncture (BFA) has gained widespread clinical use for patients presenting to emergency departments (EDs). This systematic review of randomized controlled trials (RCTs) aims to assess the efficacy and safety of BFA in ED settings. Methods: A literature search was conducted in OVID and Scopus databases for RCTs involving BFA applied in ED settings. The risk of bias was evaluated using the Cochrane Collaboration risk of bias tool, while the methodological quality of RCTs was assessed using the Jadad score. Due to the heterogeneity of the included studies, a qualitative analysis was performed. Results: Seven studies involving 758 patients met the eligibility criteria. Among these, five studies evaluated traditional BFA in conjunction with standard analgesia care, while two studies assessed modified BFA alongside standard care. Most of the included studies were found to have a high risk of bias, leading to an overall classification of low quality according to the Jadad criteria. A descriptive analysis was performed due to heterogeneity in the interventions, observational timepoints, and outcomes reported in the included studies. Positive results were demonstrated in 71% of the studies. The most common conditions documented as the primary ED presentation included back pain, acute abdominal pain, lower extremity pain, neck pain, and acute sore throat. Notably, no severe adverse events were reported. Conclusion: BFA may offer a safe adjunct to standard care for pain management in ED settings. However, the limited methodological rigor and small number of existing RCTs reduce confidence in the current evidence. Well-designed, robust studies are needed to clarify their effectiveness and support stronger clinical recommendations.
