Background: To compare the effectiveness of four surveillance strategies for detecting SARS-CoV-2 within the homeless shelter population in Hamilton, ON and assess participant adherence over time for each surveillance method.
Methods: This was an open-label, cluster-randomized controlled trial conducted in eleven homeless shelters in Hamilton, Ontario, from April 2020 to January 2021. All participants who consented to the study and participated in the surveillance were eligible for testing by self-swabbing.

Study Question: Are live birth rates (LBRs) per woman following flexible progestin-primed ovarian stimulation (fPPOS) treatment non-inferior to LBRs per woman following the conventional GnRH-antagonist protocol in expected suboptimal responders undergoing freeze-all cycles in assisted reproduction treatment?
Summary Answer: In women expected to have a suboptimal response, the 12-month likelihood of live birth with the fPPOS treatment did not achieve the non-inferiority criteria when compared to the standard GnRH antagonist protocol for IVF/ICSI treatment with a freeze-all strategy.
What Is Known Already: The standard PPOS protocol is effective for ovarian stimulation, where medroxyprogesterone acetate (MPA) is conventionally administered in the early follicular phase for ovulatory suppression. Recent retrospective cohort studies on donor cycles have shown the potential to prevent premature ovulation and maintain oocyte yields by delaying the administration of MPA until the midcycle (referred to as fPPOS), similar to GnRH antagonist injections.
Discrimination of benign, atypical, and malignant peripheral nerve sheath tumours in neurofibromatosis type 1 - intraindividual comparison of positron emission computed tomography and diffusion-weighted magnetic resonance imaging.

Background: To intraindividually compare the diagnostic performance of positron emission computed tomography (F-18-FDG-PET/CT) and diffusion-weighted magnetic resonance imaging (DW-MRI) in a non-inferiority design for the discrimination of peripheral nerve sheath tumours as benign (BPNST), atypical (ANF), or malignant (MPNST) in patients with neurofibromatosis type 1 (NF1).
Results: In this prospective single-centre study, thirty-four NF1 patients (18 male; 30 ± 11 years) underwent F-18-FDG-PET/CT and multi-b-value DW-MRI (11 b-values 0 - 800 s/mm²) at 3T. Sixty-six lesions corresponding to 39 BPNST, 11 ANF, and 16 MPNST were evaluated.
Cine-MRI of Deglutition: A Systematic Review.

Videofluoroscopy, recognized as the gold standard for dysphagia exploration, has inherent limitations, including poor soft tissue discrimination, radiation exposure, and aspiration risk. In response to these challenges, cine-MRI of swallowing has evolved over the past three decades, yielding diverse methodologies and results across various studies.This systematic review, conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, meticulously outlines cine-MRI protocols, applications, advantages, and limitations.
