AI-Native Scoping Reviews & Evidence Mapping

Impella is not a simple “more support means better outcome” device: across 194 references and 432 original studies, the evidence shows a constant trade-off between ventricular unloading, survival signals, and complications such as bleeding, hemolysis, thrombocytopenia, vascular injury, and acquired von Willebrand syndrome. The full ☸️SAIMSARA evidence map shows where Impella appears strongest — early AMI-cardiogenic shock support, high-risk PCI, bridge-to-transplant/LVAD pathways, and selected RV failure scenarios — and where the evidence remains fragile, observational, or safety-limited.

Alcohol and depression are not a simple “alcohol causes depression” story: across 185 references and 3,711 original studies, the evidence separates moderate-use signals from the consistent harms of heavy drinking, AUD, coping-motivated use, suicidality, relapse, and mortality. The full ☸️SAIMSARA evidence map gives a reference-linked view of where causality remains uncertain, which mechanisms matter clinically, and why integrated screening and treatment are needed instead of treating alcohol and depression as separate problems.

Electronic health records are not won by one “best” vendor: the evidence shows that usability, clinical decision support, interoperability, analytics readiness, workflow fit, and governance decide whether an EHR actually improves care. Built from 57 references and 130 original studies, the full ☸️SAIMSARA evidence map gives a practical, reference-linked view of what makes EHR systems work — and where they fail in real clinical settings.
