31P-magnetic resonance (MR) spectra of the heart can be obtained from well-defined myocardial regions by combined MR imaging and variable selected volumes for spectroscopy. 31P-spectra of 33 volunteers and of 43 patients with dilated and hypertrophic cardiomyopathy and with coronary artery disease were quantified using a curve-fitting routine. To optimize our technique, we recorded unsaturated and partially saturated spectra in several volunteers. Relative peak areas and signal-to-noise ratios showed significant changes with varying pulse repetition times. Saturation factors were applied to correct spectra from volunteers and patients for the effects of partial saturation. Under resting conditions, peak areas of volunteers and patients from the various groups were statistically indistinct.

Introduction And Objectives: High flow nasal cannula (HFNC) therapy is an increasingly popular mode of non-invasive respiratory support for the treatment of patients with acute hypoxemic respiratory failure (AHRF). Previous experimental studies in healthy subjects have established that HFNC generates flow-dependent positive airway pressures, but no data is available on the levels of mean airway pressure (mP) or positive end-expiratory pressure (PEEP) generated by HFNC therapy in AHRF patients. We aimed to estimate the airway pressures generated by HFNC at different flow rates in patients with AHRF, whose functional lung volume may be significantly reduced compared to healthy subjects due to alveolar consolidation and/or collapse.

Background: During COVID-19 pandemic, a rapid readjustment to continued delivery of healthcare was required. Redeployment is an intentional process to mobilise human resources by reassigning a healthcare worker to a new role or new work location, to achieve sustainable delivery of patient care. We report redeployment experiences of staff from a specialist children's hospital during first and second waves of the United Kingdom COVID-19 pandemic.

Patients: Three residents of a long-term care home volunteered to participate in a rehabilitation program involving a virtual reality blowgun game. The participants played the game 5 days a week as a new exercise routine. After 4 weeks of intervention, tongue pressure and forced expiratory volume in 1 s improved in all participants.

Ultra-rapid insulin lispro is an innovative insulin analogue designed to achieve rapid onset and short duration of action, aimed at optimizing glycemic control in patients with diabetes. This was a double-blind, randomized, 2-period, crossover clamp study to evaluate the pharmacokinetics (PK) and pharmacodynamics (PD), along with safety profiles, of a potential biosimilar ultra-rapid insulin lispro compared to the reference product in healthy White men. A total of 35 healthy volunteers completed hyperinsulinemic euglycemic clamp procedures across both study periods.

Aim: To determine the views and experiences of inpatient nurses receiving care.
Background: Switching from the care provider role to being a patient allows nurses to realise patients' real care expectations and to test their colleagues' care practices. Nurses' experience as inpatients is essential for understanding patients' care-related expectations and improving care quality by reflecting on their practices.
