Importance: Clinical practice guidelines support home-based exercise for patients with peripheral artery disease (PAD), but no randomized trials have tested whether an exercise intervention without periodic medical center visits improves walking performance.

Telemedicine and telehealth are the practices of medicine at a distance. Performing the equivalent of a complete clinical examination by telemedicine would be unusual. However, components of a more traditional clinical examination are part of the telemedicine workup for specific conditions.

INTRODUCTION: Mobile technology, when included within multicomponent interventions, could contribute to more effective weight loss.

RATIONALE: Video-based treatment in telemedicine is a potential alternative to face-to-face treatment. We describe our trial use of telemedicine to treat a patient with primary headache.

Telemedicine use in urology is an evolving practice. In this article, the authors review the early experience of telemedicine specifically as it relates to urologic practice and discuss the future implications and the utility of telemedicine as it applies to other fields.

BACKGROUND: There has been a tremendous surge in stroke prevalence in sub-Saharan Africa. Hypertension (HTN), the most potent, modifiable risk factor for stroke, is a particular challenge in sub-Saharan Africa.

BACKGROUND: Ileostomies are a routine part of the care of patients with rectal cancer, but are associated with significant risk for dehydration, readmission, and acute kidney injury.

Echocardiography is the primary imaging modality for diagnosing cardiac conditions.

BACKGROUND: Gaps in the HIV care continuum contribute to poor health outcomes and increase HIV transmission. A combination of interventions targeting multiple steps in the continuum is needed to achieve the full beneficial impact of HIV treatment.
