Polysomnographic titration of non-invasive ventilation in motor neurone disease (3TLA): study protocol for a randomised controlled trial.

Background: Non-invasive ventilation (NIV) uses positive pressure to assist people with respiratory muscle weakness or severe respiratory compromise to breathe. Most people use this treatment during sleep when breathing is most susceptible to instability. The benefits of using NIV in motor neurone disease (MND) are well-established.

Molecular basis of proton sensing by G protein-coupled receptors.

Three proton-sensing G protein-coupled receptors (GPCRs)-GPR4, GPR65, and GPR68-respond to extracellular pH to regulate diverse physiology. How protons activate these receptors is poorly understood. We determined cryogenic-electron microscopy (cryo-EM) structures of each receptor to understand the spatial arrangement of proton-sensing residues.

User-centred design of a patient portal for persons living with home mechanical ventilation and long-term tracheostomy: a mixed methods study.

Patient portals are secure online platforms that offer patients access to various functions such as personal health information. While patient portals are being increasingly offered by health services, there are limited data on their use for persons living with home mechanical ventilation (HMV) and/or long-term tracheostomy. This study, conducted at an Australian hospital's home mechanical ventilation and long-term tracheostomy services, aimed to explore the perspectives and attitudes of patients and carers regarding the introduction of a patient portal.

Do Factors Influencing Acceptance of Kidney Stone Formers as Donors Predict Subsequent Stone Events?

Purpose: This study aimed to assess whether kidney stone burden and risk factors at the time of kidney donor evaluation were associated with a symptomatic stone event post-donor evaluation.

Methods: We identified adults evaluated at Mayo Clinic (two sites) (2000-2011) for living kidney donation and had either a personal history or radiological evidence of kidney stone disease. We analyzed demographics, stone risk factors, stone number/size, and the committee's donation decision and reasons.

Assessing the impact of the COVID-19 pandemic on uptake and experiences of gestational diabetes mellitus screening in Ontario: A parallel convergent mixed-methods study.

Objective: Gestational diabetes mellitus (GDM) is a common medical complication of pregnancy that leads to adverse outcomes for both infants and pregnant people. Early detection and treatment can mitigate these negative outcomes. The COVID-19 pandemic strained healthcare and laboratory services, including GDM screening programs.
