When Regulation Travels: Distrust and Disrespect

open access: yesRegulation &Governance, EarlyView.
ABSTRACT Endeavoring to avoid the pitfalls of being too trusting of regulated entities' compliance claims, regulators sometimes create regulatory systems with elaborate requirements for verification. But as these accountability and verification regimes attempt to circumvent one set of problems, they may inadvertently create others.

An Update on Invasive Fungal Infections in Solid Organ Transplant Recipients

open access: yesTransplant Infectious Disease, EarlyView.
ABSTRACT Invasive fungal infections (IFI) remain a significant infection‐related complication in solid organ transplant recipients (SOTRs), the incidence of which has not changed overtime. With a focus on studies and data published after 2019, this narrative review provides an update on the epidemiology and prevention of IFIs in SOTRs and highlights ...

Cerebral oxygen extraction across different exercise intensities: Role of arterial PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$

open access: yesExperimental Physiology, EarlyView.
Abstract Stability in cerebral oxygen extraction fraction (OEF) is typically determined by alterations in cerebral blood flow (CBF). At rest, arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$) and OEF exhibit a strong inverse relationship owing to the powerful influence of PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$

Pulmonary arterial mechanoreceptors mediate sustained sympathoexcitation during high altitude hypoxia in humans

open access: yesExperimental Physiology, EarlyView.
Abstract Sympathetic nervous system activation is a hallmark of high‐altitude hypoxia, yet the afferent mechanisms remain incompletely defined. We examined the relative contributions of pulmonary arterial mechanoreceptors and carotid chemoreceptors – two excitatory pathways co‐activated by hypoxia – to sustained sympathoexcitation at altitude.

Daily hot‐water immersion preserves altitude‐induced haemoglobin mass expansion following descent independent of erythropoietin

open access: yesExperimental Physiology, EarlyView.
Abstract High‐altitude exposure increases haemoglobin mass (Hbmass), a key determinant of arterial oxygen‐carrying capacity, but following descent this adaptation can regress toward baseline within 7 days. Long‐term heat acclimation has emerged as an alternative stimulus for Hbmass expansion; however, whether post‐altitude passive‐heat exposure can ...

Maximal exercise at high altitude does not exacerbate inflammation in the human brain

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend This study investigated arterial–internal jugular venous (IJV) exchange of cytokines in response to low‐intensity and maximal cycling exercise at sea level and following 6–8 days at 3800 m a.s.l. There was a shift towards net release of interleukin‐6 (IL‐6), interleukin‐8 (IL‐8), monocyte chemoattractant protein‐1 (MCP‐1) and ...

The role of group III/IV afferent feedback in the ventilatory, pressor and metabolic responses to exercise in normoxia and hypoxia

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Participants completed cycling exercise with (placebo) and without (25 µg intrathecal fentanyl) intact group III/IV muscle afferent feedback in three settings: normoxia, acute hypoxia and chronic hypoxia after 7–9 days of acclimatisation (∼3800 m). Blocking afferent feedback suppressed exercise hyperpnoea across all environments,
