Evaluation of Patients With Non-obstructive Coronary Arteries
Recruiting
Patients with angina and non-obstructive CAD are common within clinical practice, but remain a challenge with regard to diagnosis and treatment. When these patients undergo a comprehensive evaluation at the time of invasive coronary angiography, occult coronary abnormalities are frequently found. We hope to learn the overall prevalence and presentation of these occult coronary abnormalities and its long term outcome in this patient population.

Milk Volume Outcomes Following Oral Nicotinamide Riboside Supplementation in Mothers of Extremely Preterm Infants
Recruiting
Breastfeeding has well-established immunity and developmental benefits for newborns, yet mothers of preterm infants often struggle to provide sufficient breast milk. The investigators hypothesize that supplementing mothers of preterm infants with nicotinamide riboside (NR) during early postpartum will result in increased milk production. NR is a unique precursor to NAD+, which functions in whole-body metabolism, including that which supports the elevated energy demands of lactation. In lactating... Read More

Fluoroscopic Versus Ultrasound Guidance for Cooled Radiofrequency Ablation of Geniculate Nerves in Knee Osteoarthritis: A Randomized Control Trial
Recruiting
Cooled radiofrequency ablation (cRFA) of the knee geniculate nerves is a promising treatment option for knee osteoarthritis, but has variable efficacy. Fluoroscopy is the typical guidance of choice, but uses bony landmarks to target these nerves which have variable positions around the knee. Alternatively, ultrasound allows for targeting based on visualization of bony landmarks, the nerves, and their accompanying vascular structures, and thus may offer greater accuracy. However, there are few st... Read More

Polyphenols and Cognitive Decline
Recruiting
Globally, populations are aging thereby increasing healthcare burden, overall cognitive impairment, and dementia including Alzheimers diseases (AD). The lack of effective treatments makes it essential to develop new strategies for healthy cognitive aging, including interventions to slow or prevent cognitive decline. A traditional Mediterranean diet, rich in polyphenols (PPs), may prevent or delay the onset of cognitive dysfunction in older adults, preserving healthy brain structure and function,... Read More
