The Arteriovenous Access Stage (AVAS) classification simplifies information about suitability of vessels for vascular access (VA). It's been previously validated in a clinical study. Here, AVAS performance was tested against multiple ultrasound mapping measurements using machine learning.

This case report details a 65-year-old Black male patient with a history of hypertension and smoking who presented with a myocardial infarction. Despite no significant abnormalities apart from the infarction, invasive coronary angiography revealed a dominant right coronary artery (RCA) and an anomalous left main coronary artery (LMCA) originating from the right coronary sinus, bifurcating into the left anterior descending artery and circumflex artery.

It divides patients into classes within three main groups: suitable for native fistula (AVAS1) or prosthetic graft (AVAS2), and patients not suitable for conventional native or prosthetic VA (AVAS3). We validated this system on a prospective dataset.

- Substantial sleep impairment is increasingly recognized in Alzheimer's disease (AD), with early sleep-wake cycle alterations noted even in individuals without cognitive decline.
- This review investigates the complex relationship between sleep disturbances and AD, highlighting how sleep issues may contribute to the disease's development and vice versa.
- The findings suggest that addressing sleep homeostasis could be a modifiable risk factor for AD, emphasizing the need for non-pharmacological interventions and further research to improve outcomes for those affected.
Article Synopsis
- The study explores the use of coronofrontal rhytidectomy (CFR) to treat severe eyelid issues in dogs, specifically pseudoptosis and superior entropion, while offering guidelines for surgical techniques based on individual cases.
- Data was collected from medical records of 20 dogs over 21 years, with key findings including a high prevalence of entropion, conjunctivitis, and other eye conditions, alongside successful outcomes from various surgical methods.
- The results indicate that CFR is highly effective, achieving over 90% success in correcting eyelid positioning, with no reported complications post-surgery.
