Purpose of review: This article presents an overview of the main technologies used to estimate gait parameters, focusing on walking speed (WS).

Recent findings: New wearable and environmental technologies to estimate WS have been developed in the last five years. Wearable technologies refer to sensors attached to parts of the patient's body that capture the kinematics during walking. Alternatively, environmental technologies capture walking patterns using external instrumentation. In this review, wearable and external technologies have been included.From the different works reviewed, external technologies face the challenge of implementation outside controlled facilities; an advantage that wearable technologies have, but have not been fully explored. Additionally, systems that can track WS changes in daily activities, especially at-home assessments, have not been developed.

Summary: Walking speed is a gait parameter that can provide insight into an individual's health status. Image-based, walkways, wearable, and floor-vibrations technologies are the most current used technologies for estimating WS. In this paper, research from the last five years that explore each technology's capabilities on WS estimation and an evaluation of their technical and clinical aspects is presented.

Purpose of the review: Iron deficiency in heart failure has been associated with impaired functional capacity and quality of life. The purpose of this paper is to review mechanisms of iron homeostasis and current clinical data exploring mechanisms of iron repletion in heart failure.

Recent finding: Multiple international societies now advise iron repletion for symptomatic heart failure patients with iron deficiency. Due to the chronic inflammation in heart failure, iron deficiency in heart failure is classically defined as ferritin < 100 µg/L or ferritin 100-300 µg/L and transferrin saturation < 20%. Multiple randomized clinical trials have demonstrated benefit from intravenous iron repletion, though studies have predominantly focused on functional capacity and quality of life. A recent study, AFFIRM-AHF, supports the treatment of iron deficiency identified during acute heart failure admissions, noting a reduction in future heart failure hospitalizations. Studies examining iron repletion in patients with heart failure with preserved ejection fraction are currently in process.

Summary: Iron homeostasis is maintained predominantly through the regulation of iron absorption, keeping iron levels tightly controlled in the normal state regardless of iron intake. In chronic heart failure however, iron homeostasis becomes dysregulated with resulting iron deficiency in many patients, with and without associated anemia. Iron is a critical element not only for erythropoiesis and oxygen carrying, but also for energy production at the level of the mitochondria and in other cell processes. We thus propose a standardized approach be utilized to screen and treat heart failure patients with iron deficiency.

Purpose of review: Most aging Americans lack access to specialist palliative care aimed at those experiencing serious illness and/or high symptom burden at end of life. The curricula used by training programs for all healthcare professions should focus on helping learners develop the primary palliative care skills and competencies necessary to provide compassionate bias-free care for adults with serious illness. We believe there is much opportunity to improve this landscape via the incorporation of palliative care competencies throughout generalist healthcare professional programs.

Recent findings: Several recent publications highlight multiple issues with recruitment and retention of diverse students and faculty into healthcare professional training programs. There are also concerns that the curricula are reinforcing age, race, and gender biases. Due to these biases, healthcare professionals graduate from their training programs with socialized stereotypes unquestioned when caring for older adult minority patients and caregivers.

Summary: Important lessons must be incorporated to assure that bias against age, race, and gender are discovered and openly addressed in healthcare professional's education programs. This review highlights these three types of bias and their interrelationships with the aim of revealing hidden truths in the education of healthcare professionals. Ultimately, we offer targeted recommendations of focus for programs to address implicit bias within their curricula.
