Home-Based Exercise and Self-Management After Lung Cancer Resection: A Randomized Clinical Trial.

Importance: Patients with lung cancer have poor physical functioning and quality of life. Despite promising outcomes for those who undertake exercise programs, implementation into practice of previously tested hospital-based programs is rare.

Objective: To evaluate a home-based exercise and self-management program for patients after lung resection.

Modeling sex-specific whole-body metabolic responses to feeding and fasting.

Men generally favor carbohydrate metabolism, while women lean towards lipid metabolism, resulting in significant sex-based differences in energy oxidation across various metabolic states such as fasting and feeding. These differences are influenced by body composition and inherent metabolic fluxes, including increased lipolysis rates in women. However, understanding how sex influences organ-specific metabolism and systemic manifestations remains incomplete.

Study protocol for a single-site feasibility study evaluating the adoption and fidelity of Prep-4-RT: prehabilitation for head and neck cancer patients undergoing radiotherapy.

Introduction: Prep-4-RT is a co-designed stepped-care multimodal prehabilitation program for people scheduled to receive radiotherapy for head and neck cancer (HNC). Prehabilitation, which occurs between diagnosis and treatment commencement, aims to improve a patient's health to reduce the incidence and severity of current and future impairments. HNC treatment can be distressing and has detrimental impacts on function and quality of life.

"How Do I Test the Waters? How Do I Go Forward?": Codesigning a Supportive Pathway after Critical Illness.

Long-term recovery after critical illness can be affected by post-intensive care syndrome (PICS), a significant burden, which can impact return to activities and work. There is a need for streamlined support for intensive care unit (ICU) patients in their recovery while enduring PICS symptoms. To explore critical illness recovery from the experiences, perspectives, and beliefs of former ICU patients, their caregivers, and multidisciplinary clinicians to design a future rehabilitation intervention prototype to support ICU patients.

Sexual Dimorphism in Substrate Metabolism During Exercise.

During aerobic exercise, women oxidize significantly more lipids and less carbohydrates than men. This sexual dimorphism in substrate metabolism has been attributed, in part, to the observed differences in epinephrine and glucagon levels between men and women during exercise. To identify the underpinning candidate physiological mechanisms for these sex differences, we developed a sex-specific multi-scale mathematical model that relates cellular metabolism in the organs to whole-body responses during exercise.
