Maternal and infant gut microbiome

open access: yesiMeta, EarlyView.
The maternal–infant continuum involves critical windows of host–microbiota co‐adaptation. Preconception, maternal and paternal microbiomes modulate immunity and reproduction. During pregnancy, a gut–placenta axis emerges, where microbial metabolites influence fetal growth or contribute to complications like gestational diabetes mellitus (GDM ...

Normothermic Machine Perfusion vs. Static Cold Storage for DBD Liver Transplantation in High‐MELD Recipients: A Single‐Center Retrospective Study

open access: yesJournal of Hepato-Biliary-Pancreatic Sciences, EarlyView.
ABSTRACT Background and Purpose While normothermic machine perfusion (NMP) has benefits over static cold storage (SCS), its efficacy in high‐acuity recipients with high Model for End‐Stage Liver Disease (MELD) scores, particularly using a back‐to‐base application model, is not well established.

Time-dependent effects of prone position on ventilation-perfusion matching assessed by electrical impedance tomography in patients with COVID-19 ARDS: sub-analysis of a prospective physiological study

open access: yesAnnals of Intensive Care
Background Prone positioning (PP) has been shown to improve oxygenation in patients with acute respiratory distress syndrome (ARDS); with a focus on its early physiological effects. However, the time-dependent effects of PP on ventilation-perfusion (V/Q)

Complaints Involving Sonographers: What Three Decades of Cases From A Public New Zealand Database Can Teach Us

open access: yesJournal of Medical Radiation Sciences, EarlyView.
Health consumer complaints to the New Zealand Health and Disability Commissioner involving sonographers are rare, totalling 15 in the last 31 years and averaging 1.5 cases per year over the last decade. A large proportion of complaints involve an undetected finding, obstetric examination and private setting.

Kaempferol Attenuates Myocardial Ischemia–Reperfusion Injury by Suppressing Ferroptosis via the KEAP1–Nrf2–GPX4 Axis

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Myocardial ischemia/reperfusion (I/R) injury is characterized by cardiomyocyte death, excessive oxidative stress, inflammation, and ferroptosis, which collectively limit the efficacy of reperfusion therapy. In this study, we investigated whether kaempferol (KAE), a natural flavonol with antioxidative and antiinflammatory properties, could ...

“Two‐For‐One”: 4D Cardiac and Pulmonary MR Imaging From a Single Acquisition Using bSTAR

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To generate 4D (3D+time) images of both the heart and lungs using a single volumetric radial free‐breathing bSSFP dual echo acquisition (bSTAR) with two image reconstructions within a single pipeline deployed inline at 0.55 and 1.5 T.

Correlating Pulmonary Hemodynamics With HP 129Xe Dissolved‐Phase MRSI in a Controlled Porcine Intervention Study

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Pulmonary hypertension is related to a 1‐year mortality ranging from < 5% to > 20% in low‐ and high‐risk groups. Right heart catheterization is the diagnostic gold standard, associated with a 1.1% rate of severe adverse events, posing the need for a non‐invasive diagnostic tool.

Calibration‐Free Estimation of Cerebrovascular Reactivity From Resting‐State BOLD fMRI Using Reconstructed Respiratory Fluctuations

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Cerebrovascular reactivity (CVR) provides an important index of vascular health and is conventionally quantified using a hypercapnic gas or breath‐hold challenge in conjunction with blood‐oxygen‐level‐dependent functional magnetic resonance imaging (BOLD‐fMRI).
