Catch-AF-Early Diagnosis of Symptomatic Arrythmias in the Waiting Period Prior to Seeing a Cardiologist in Victoria, British Columbia.

Background: Atrial fibrillation (AF) is the most common cardiac arrhythmia. Given its often-paroxysmal nature, screening at a single time point, using a 12-lead electrocardiogram (ECG) or a Holter monitor, has limited benefit. The AliveCor KardiaMobile device is a validated ECG recorder that can be used for patient-directed arrhythmia diagnosis and symptom-rhythm correlation.

Variational Hirshfeld Partitioning: General Framework and the Additive Variational Hirshfeld Partitioning Method.

We introduce the general mathematical framework of variational Hirshfeld partitioning, wherein the best possible approximation to a molecule's electron density is obtained by minimizing the -divergence between the molecular density and a non-negative linear combination of (normalized) basis functions. This framework subsumes several existing methods that variationally optimize their pro-atoms, like (Gaussian) iterative stockholder analysis (ISA and GISA) and minimal basis iterative stockholder partitioning (MBIS), and provides a solid foundation for developing mathematically rigorous partitioning schemes. In this paper, we delve into the mathematical underpinnings of Hirshfeld-inspired partitioning schemes and show that among all the valid -divergence measures only the extended Kullback-Leibler is a suitable choice.

Triple therapy: Three departments collaborating to train medical students in rural settings.

The primary healthcare (PHC) rotation places medical students in rural district hospitals for 4 weeks during their 4th or 5th year. This rotation is a collaboration among three academic units at Stellenbosch University's Faculty of Medicine and Health Sciences. Learning activities during this rotation include participation in a longitudinal community-oriented primary care project, conducting rehabilitation-oriented home visits to persons with disabilities, and assessing and treating patients presenting with undifferentiated problems on an in- and outpatient basis.
