Multi-Object Tracking and Segmentation via Neural Message Passing
Graphs offer a natural way to formulate Multiple Object Tracking (MOT) and
Multiple Object Tracking and Segmentation (MOTS) within the
tracking-by-detection paradigm. However, they also introduce a major challenge
for learning methods, as defining a model that can operate on such structured
domain is not trivial. In this work, we exploit the classical network flow
formulation of MOT to define a fully differentiable framework based on Message
Passing Networks (MPNs). By operating directly on the graph domain, our method
can reason globally over an entire set of detections and exploit contextual
features. It then jointly predicts both final solutions for the data
association problem and segmentation masks for all objects in the scene while
exploiting synergies between the two tasks. We achieve state-of-the-art results
for both tracking and segmentation in several publicly available datasets. Our

Continuous positive airway pressure therapy is associated with improvement in overactive bladder symptoms in women with obstructive sleep apnea syndrome
Introduction To evaluate the impact of continuous positive airway pressure (CPAP) therapy on overactive bladder (OAB) symptoms in women with obstructive sleep apnea syndrome (OSAS).
Material and methods One-hundred and fifty women underwent an overnight polysomnography study between May 2014 and September 2014. Their voiding symptoms were evaluated using the OAB symptom score (OABSS) and International Consultation on Incontinence Questionnaire Short-Form at OSAS diagnosis and approximately 3-months after CPAP therapy. OSAS severity was assessed according to the apnea-hypopnea-index.
Results We evaluated 140 women and 111 of them (79.3%) reported symptoms consistent with OAB. There were no statistically significant differences between OSAS severity with a prevalence of OAB (p = 0.92). The prevalence of urinary incontinence (UI) was 35.7% (n = 50) and 39.6% (n = 44) in all patients and patients with OAB, respectively. There were no statistically significant differences between UI with OAB (p = 0.58). Baseline OABSS is comparable between OSAS severity (p = 0.143). After 3-months CPAP therapy, OABSS and ICIQ-SF sum scores were significantly decreased in patients with severe and moderate OSAS (p < 0.01), however, change of OABSS sum score was insignificant in patients with mild OSAS (p = 0.44).
Conclusions CPAP therapy improves the OAB, OABSS and ICIQ-SF scores in women with severe and moderate OSAS. OSAS-induced OAB may be alleviated following CPAP therapy
