Microresonator frequency comb-based high-speed data transmission provides a pathway towards augmented data capacity without increasing the number of laser sources. Their use with intensity-modulated direct detection modulation (IMDD) formats is especially pertinent in data center communications where minimizing cost, latency and complexity is paramount. This however implies that the same extent of digital signal processing techniques commonly used in coherent detection for the management of fiber impairments including chromatic dispersion are not available.

- Cardiac complications, known as stroke-heart syndrome (SHS), can occur after ischemic stroke, increasing mortality risk in patients.
- In a study involving 15,054 ischemic stroke patients, 11.8% developed SHS, with significant death rates linked to when SHS symptoms appeared, especially 10 to 30 days post-stroke.
- The most common SHS manifestation, ECG abnormalities, along with acute myocardial injury and heart failure, presented the highest 90-day death risk in affected patients.
Background: The prediction of ischaemic stroke in patients with heart failure with reduced ejection fraction (HFrEF) but without atrial fibrillation (AF) remains challenging. Our aim was to evaluate the performance of machine learning (ML) in identifying the development of ischaemic stroke in this population.
Methods: We performed a post-hoc analysis of the WARCEF trial, only including patients without a history of AF.
Article Synopsis
- * An observational study of 74,372 pwMS over 5 years found that 9% had deficient and 18% had inadequate vitamin D levels, both associated with a higher incidence of major adverse cardiovascular events (MACE).
- * Vitamin D supplementation (cholecalciferol) did not reduce the elevated CVD risk in pwMS with deficient or inadequate vitamin D levels compared to those with adequate levels.
Orbital cellulitis is an infection of the orbital tissue behind the orbital septum. We report a case of a 71-year-old Malay lady, a passive smoker for 20 years, presenting with recurrent orbital cellulitis at the same site. She initially presented with right periorbital swelling, redness, and reduced vision worsening over two weeks, along with a firm swelling over the right temple.
