recommendations! Published in 2023 at "Magnetic Resonance in Medicine"

DOI: 10.1002/mrm.29639

Abstract: Cardiac‐related intracranial pulsatility may relate to cerebrovascular health, and this information is contained in BOLD MRI data. There is broad interest in methods to isolate BOLD pulsatility, and the current study examines a deep learning… read more here.

DOI: 10.1007/5584_2018_155

Abstract: In the cerebrospinal fluid (CSF) circulation, two components can be distinguished: bulk flow (circulation) and pulsatile flow (back and forth motion). CSF pulsatile flow is generated by both cardiac and respiratory cycles. Recent years have… read more here.

DOI: 10.1007/s00246-021-02599-w

Abstract: It is unclear whether residual anterograde pulmonary blood flow (APBF) at the time of Fontan is beneficial. Pulsatile pulmonary flow may be important in maintaining a compliant and healthy vascular circuit. We, therefore, wished to… read more here.

DOI: 10.1007/s00246-022-02839-7

Abstract: Infants with congenital heart disease are known to have higher rates of necrotizing enterocolitis (NEC) which is associated with poorer outcomes. Although the etiology is recognized as distinct from the premature neonatal population, there is… read more here.

DOI: 10.1016/j.avsg.2020.07.030

Abstract: INTRODUCTION Neuromuscular electrical stimulator (NMES) devices increase blood flow to the lower limb by a process of intermittent muscular contraction initiated by a transdermal stimulus to the common peroneal nerve. However, its effects on localised… read more here.

DOI: 10.1016/j.bbe.2020.07.008

Abstract: Abstract The neural baroreflex, which regulates mean arterial pressure (MAP) via the action of the brain, consists of baroreceptors which measure MAP, and actuators that can produce a change in MAP, such as the heart… read more here.

DOI: 10.1016/j.exger.2021.111459

Abstract: BACKGROUND Elevated renal flow pulsatility may contribute to the pathogenesis of chronic kidney disease (CKD). The purpose of this study was to investigate the associations among age, renal flow pulsatility, and CKD biomarkers in non-CKD… read more here.

DOI: 10.1016/j.jacc.2018.02.075

Abstract: BACKGROUND The main risk factor for bleeding in patients with continuous-flow mechanical circulatory support (CF-MCS) is the acquired von Willebrand factor (VWF) defect related to the high shear-stress forces developed by these devices. Although a… read more here.

DOI: 10.1016/j.neurobiolaging.2021.05.002

Abstract: Aging is accompanied by global brain atrophy occurring unequally across the brain. Cortical thinning is seen with aging with a larger loss in the frontal and temporal subregions. We explored the link between regional cortical… read more here.

DOI: 10.1093/icvts/ivx236

Abstract: OBJECTIVES Continuous-flow left ventricular assist devices (CF-LVADs) are widely used to treat patients with end-stage heart failure. Although continuous flow is different from physiological flow, patients show improved outcomes after CF-LVAD implantation. A novel rotational… read more here.
