Signs and Symptoms

The objective of this study is to assess the safety and efficacy of the Freesolve resorbable magnesium scaffold (RMS) in the treatment of subjects with up to two de novo lesions in native coronary arteries compared to the Xience coronary drug-eluting stent (DES) system

This registry prospectively collects anonymized free-text symptom descriptions submitted voluntarily by adults through the OpenGenome platform at opengenome.bio. For each submission, the system retrieves real biomedical literature from PubMed and ClinicalTrials.gov in parallel, applies a constrained reasoning model operating under a strict output schema, and returns a structured biological signal report. The study evaluates the internal consistency of extracted signals, the calibration of confidence scores relative to dataset size and symptom specificity, and the distribution of biological signal categories across a large anonymous population. No intervention is assigned. No participant contact occurs. All data is anonymized at the point of collection.

Adrenomedullin is a neuropeptide implicated in the pathogenesis of migraine. This study investigates whether its administration, after pre-treatment with erenumab (a CGRP-receptor blocking monoclonal antibody), can trigger migraine attacks in individuals with migraine without aura.

Pramlintide is a peptide analogue of human amylin which is a vasoactive substance involved in the pathogenesis of headache. This study investigates whether pramlintide induces migraine-like headache in people with persistent post-traumatic headache (PTH) attributed to mild traumatic brain injury (mTBI).

Anesthesia is a drug induced, reversible, comatose state that facilitates surgery and it is widely assumed that cognition returns to baseline after anesthetics have been eliminated. However, many patients have persistent memory impairment for weeks to months after surgery. Cardiac surgery appears to carry the highest risk of postoperative cognitive dysfunction (POCD). These cognitive deficits are associated with increased mortality, prolonged hospital stay and loss of independence. The investigators propose to investigate the role of Dexmedetomidine (DEX) in preventing long-term POCD after cardiac surgery and enhancing early postoperative recovery. It is anticipated that DEX will be the first effective preventative therapy for POCD, improve patient outcomes, and reduce length of stay and healthcare costs.
